De Quervain's subacute thyroiditis presenting as a painless solitary thyroid nodule. (1/65)
We describe a 39-year-old woman presenting with a painless solitary thyroid nodule, initially without signs suggesting thyroiditis. The serum level of thyrotropin was suppressed whereas those of thyroxine and triiodothyronine were normal. Fine needle aspiration cytology showed no signs of inflammation or malignancy. One week later, the patient felt pain and tenderness on her neck, and erythrocyte sedimentation rate and C-reactive protein were markedly elevated. Thyroid scintigraphy showed a suppressed thyroid pertechnetate uptake. At that time, the diagnosis of subacute thyroiditis was made. Upon treatment with steroids the patient's symptoms as well as the thyroid nodule resolved. This case illustrates that subacute thyroiditis de Quervain may present as a solitary, painless nodule with suppressed thyrotropin and should therefore be considered in the differential diagnosis of such lesions. (+info)Thyroiditis: differential diagnosis and management. (2/65)
Thyroiditis is a group of inflammatory thyroid disorders. Patients with chronic lymphocytic thyroiditis (also referred to as Hashimoto's thyroiditis) present with hypothyroidism, goiter, or both. Measurement of serum thyroid autoantibodies and thyroglobulin confirms the diagnosis. Subacute granulomatous thyroiditis (sometimes referred to as de Quervain's disease) is a self-limited but painful disorder of the thyroid. Physical examination, elevated erythrocyte sedimentation rate, elevated thyroglobulin level and depressed radioactive iodine uptake (RAIU) confirm the diagnosis. Subacute lymphocytic thyroiditis (silent thyroiditis) is considered autoimmune in origin and commonly occurs in the postpartum period. Symptoms of hyperthyroidism and depressed RAIU predominate. Acute (suppurative) thyroiditis is a rare, infectious thyroid disorder caused by bacteria and other microbes. The rare, invasive fibrous thyroiditis (Riedel's thyroiditis) presents with a slowly enlarging anterior neck mass that is sometimes confused with a malignancy. (+info)Sweet's syndrome and subacute thyroiditis. (3/65)
A 63 year old woman developed biopsy documented lesions of acute febrile neutrophilic dermatosis (Sweet's syndrome) one week after the onset of subacute thyroiditis. This is only the second reported case of such an association. The role of cytokines in the development of both subacute thyroiditis and Sweet's syndrome may be the link between these two conditions. (+info)Historical perspective of foamy virus epidemiology and infection. (4/65)
Foamy viruses (FV) are complex retroviruses which are widespread in many species. Despite being discovered over 40 years ago, FV are among the least well characterized retroviruses. The replication of these viruses is different in many interesting respects from that of all other retroviruses. Infection of natural hosts by FV leads to a lifelong persistent infection, without any evidence of pathology. A large number of studies have looked at the prevalence of primate foamy viruses in the human population. Many of these studies have suggested that FV infections are prevalent in some human populations and are associated with specific diseases. More recent data, using more rigorous criteria for the presence of viruses, have not confirmed these studies. Thus, while FV are ubiquitous in all nonhuman primates, they are only acquired as rare zoonotic infections in humans. In this communication, we briefly discuss the current status of FV research and review the history of FV epidemiology, as well as the lack of pathogenicity in natural, experimental, and zoonotic infections. (+info)Cytomegalovirus pneumonitis, activated prothrombin time prolongation and subacute thyroiditis after unrelated allogeneic bone marrow transplantation. (5/65)
A 22-year-old female with acute myeloid leukemia (AML) in complete remission received a conditioning regimen containing antithymocyte globulin for an unrelated bone marrow transplant (BMT). After BMT, the patient suffered from cytomegalovirus (CMV) pneumonitis with markedly high levels of CMV antigenemia, activated prothrombin time (APTT) prolongation, and subacute thyroiditis. Recovery of CD4+ cells was delayed as long as 1 year after BMT. An association between these three episodes and viral infection due to the delayed recovery of CD4+ cells is suggested. (+info)Evaluation of recurrence in 36 subacute thyroiditis patients managed with prednisolone. (6/65)
OBJECTIVE: The incidence of subacute thyroiditis (SAT) is low and there are a few reports of recurrence of subacute thyroiditis. Current treatment protocols for SAT are not uniform. Prednisolone (PSL) is chosen more often for treatment than nonsteroidal anti-inflammatory drugs. This study was undertaken to confirm the recurrence rate of SAT managed by PSL, and to compare the initial laboratory data between the recurrent and the non-recurrent groups. METHODS: After diagnosis, all patients were treated with PSL (starting at 30 mg or 25 mg per day, tapered by 5 mg per week) for 5 or 6 weeks. We evaluated data and symptoms at the first visit and during the therapy. PATIENTS: Thirty-six patients who received only PSL for SAT at our hospital between January 1997 and December 1998 were referred. These patients asked to visit every 2 weeks for the monitoring of symptoms and laboratory data. RESULTS: SAT symptoms recurred in eight patients (22%), most upon cessation of PSL. There was no difference in initial serum sialic acid, erythrocyte sedimentation rate, C-reactive protein, thyroglobulin, serum free thyroxine and free triiodothyronine before PSL treatment between the recurrent and non-recurrent patient populations. CONCLUSIONS: The recurrence rate of SAT with treated PSL is about 20%. There was no difference in the laboratory data before starting the therapy between recurrent and non-recurrent groups. Therefore, a modified protocol of PSL administration may be needed to decrease the early recurrent rate of SAT. (+info)Familial occurrence of subacute thyroiditis. (7/65)
Although subacute thyroiditis (de Quervain's thyroiditis) is presumed to be caused by a viral infection, only 2 familial occurrences of subacute thyroiditis have been reported in the literature. Typical and severe subacute thyroiditis was diagnosed in an older sister who was hospitalized for 8 days. During this period her younger sister nursed her. Three weeks after, the same clinical picture occurred in the younger sister. We postulate that subacute thyroiditis might occur by transmission of possible viral infection in genetically predisposed individuals. (+info)CT and MR imaging findings associated with subacute thyroiditis. (8/65)
Subacute granulomatous thyroiditis is an uncommon disease that occurs most often in women in their second to fifth decades of life. This disease usually presents with thyroid tenderness, a low grade fever, and occasional dysphagia. The disease resolves spontaneously, usually without thyroid function abnormalities. We herein present the CT and MR imaging findings of two cases of subacute granulomatous thyroiditis. (+info)Autoimmune thyroiditis, also known as Hashimoto's disease, is a chronic inflammation of the thyroid gland caused by an autoimmune response. In this condition, the immune system produces antibodies that attack and damage the thyroid gland, leading to hypothyroidism (underactive thyroid). The thyroid gland may become enlarged (goiter), and symptoms can include fatigue, weight gain, cold intolerance, constipation, dry skin, and depression. Autoimmune thyroiditis is more common in women than men and tends to run in families. It is often associated with other autoimmune disorders such as rheumatoid arthritis, Addison's disease, and type 1 diabetes. The diagnosis is typically made through blood tests that measure levels of thyroid hormones and antibodies. Treatment usually involves thyroid hormone replacement therapy to manage the symptoms of hypothyroidism.
Subacute thyroiditis, also known as de Quervain's thyroiditis or granulomatous thyroiditis, is a inflammatory disorder of the thyroid gland. It is characterized by the presence of granulomas, which are collections of immune cells, within the thyroid tissue. The condition often follows an upper respiratory infection and is more common in women than men.
Subacute thyroiditis typically presents with pain and tenderness in the front of the neck, along with systemic symptoms such as fatigue, weakness, and low-grade fever. The disorder can cause hyperthyroidism (overactive thyroid) initially, followed by hypothyroidism (underactive thyroid) as the gland becomes damaged and inflamed. In some cases, the thyroid function may return to normal on its own after several months. Treatment typically involves anti-inflammatory medications to reduce pain and inflammation, and beta blockers to manage symptoms of hyperthyroidism.
Hashimoto's disease, also known as chronic lymphocytic thyroiditis, is an autoimmune disorder in which the immune system mistakenly attacks and damages the thyroid gland. The resulting inflammation often leads to an underactive thyroid gland (hypothyroidism). It primarily affects middle-aged women but can also occur in men and women of any age and in children.
The exact cause of Hashimoto's disease is unclear, but it appears to involve interactions between genetic and environmental factors. The disorder tends to run in families, and having a family member with Hashimoto's disease or another autoimmune disorder increases the risk.
Symptoms of hypothyroidism include fatigue, weight gain, constipation, cold intolerance, joint and muscle pain, dry skin, thinning hair, irregular menstrual periods, and depression. However, some people with Hashimoto's disease may have no symptoms for many years.
Diagnosis is typically based on a combination of symptoms, physical examination findings, and laboratory test results. Treatment usually involves thyroid hormone replacement therapy, which can help manage symptoms and prevent complications of hypothyroidism. Regular monitoring of thyroid function is necessary to adjust the dosage of medication as needed.
Suppurative thyroiditis is a rare type of thyroid gland inflammation that is caused by a bacterial infection. It is characterized by the formation of pus (suppuration) within the thyroid tissue. The infection can result from a direct spread of bacteria from adjacent structures, such as the upper respiratory tract or neck, or through the bloodstream due to an underlying infection elsewhere in the body.
Suppurative thyroiditis primarily affects people with pre-existing conditions that weaken the immune system, making them more susceptible to bacterial infections. These conditions may include diabetes, HIV/AIDS, or alcoholism. Additionally, it can occur in individuals who have recently undergone surgical procedures on the thyroid gland or after a traumatic injury to the area.
Symptoms of suppurative thyroiditis include fever, chills, painful swallowing, neck pain and swelling, difficulty breathing, hoarseness, and symptoms related to bacteremia (bacterial infection in the blood) if the infection spreads. Diagnosis typically involves a combination of clinical evaluation, imaging studies like ultrasound or CT scan, and laboratory tests to identify the causative organism. Treatment usually consists of antibiotics to eliminate the bacterial infection and possible surgical drainage of the infected thyroid tissue in severe cases.
Thyroglobulin is a protein produced and used by the thyroid gland in the production of thyroid hormones, primarily thyroxine (T4) and triiodothyronine (T3). It is composed of two subunits, an alpha and a beta or gamma unit, which bind iodine atoms necessary for the synthesis of the thyroid hormones. Thyroglobulin is exclusively produced by the follicular cells of the thyroid gland.
In clinical practice, measuring thyroglobulin levels in the blood can be useful as a tumor marker for monitoring treatment and detecting recurrence of thyroid cancer, particularly in patients with differentiated thyroid cancer (papillary or follicular) who have had their thyroid gland removed. However, it is important to note that thyroglobulin is not specific to thyroid tissue and can be produced by some non-thyroidal cells under certain conditions, which may lead to false positive results in some cases.
The thyroid gland is a major endocrine gland located in the neck, anterior to the trachea and extends from the lower third of the Adams apple to the suprasternal notch. It has two lateral lobes, connected by an isthmus, and sometimes a pyramidal lobe. This gland plays a crucial role in the metabolism, growth, and development of the human body through the production of thyroid hormones (triiodothyronine/T3 and thyroxine/T4) and calcitonin. The thyroid hormones regulate body temperature, heart rate, and the production of protein, while calcitonin helps in controlling calcium levels in the blood. The function of the thyroid gland is controlled by the hypothalamus and pituitary gland through the thyroid-stimulating hormone (TSH).
Postpartum thyroiditis is a condition that affects the thyroid gland in women after childbirth. It is characterized by inflammation of the thyroid gland, which can lead to dysfunction of the gland and abnormal levels of thyroid hormones in the body. Postpartum thyroiditis typically occurs in two phases:
1. Hyperthyroid phase: In this phase, which can last for up to 3 months after childbirth, the inflamed thyroid gland releases excess thyroid hormones into the bloodstream, leading to hyperthyroidism. Symptoms of hyperthyroidism may include anxiety, irritability, rapid heart rate, tremors, weight loss, and heat intolerance.
2. Hypothyroid phase: After the hyperthyroid phase, some women may develop hypothyroidism as the thyroid gland becomes damaged and is no longer able to produce sufficient amounts of thyroid hormones. This phase can last for several months and may be followed by a return to normal thyroid function or chronic hypothyroidism. Symptoms of hypothyroidism include fatigue, weight gain, cold intolerance, constipation, dry skin, and depression.
Postpartum thyroiditis is thought to affect up to 10% of women after childbirth, and it is more common in women with a history of thyroid disease or other autoimmune disorders. It is important for women who experience symptoms of postpartum thyroiditis to seek medical attention, as proper diagnosis and treatment can help manage the condition and prevent complications.
Graves' disease is defined as an autoimmune disorder that leads to overactivity of the thyroid gland (hyperthyroidism). It results when the immune system produces antibodies that stimulate the thyroid gland, causing it to produce too much thyroid hormone. This can result in a variety of symptoms such as rapid heartbeat, weight loss, heat intolerance, and bulging eyes (Graves' ophthalmopathy). The exact cause of Graves' disease is unknown, but it is more common in women and people with a family history of the disorder. Treatment may include medications to control hyperthyroidism, radioactive iodine therapy to destroy thyroid tissue, or surgery to remove the thyroid gland.
Thyroxine (T4) is a type of hormone produced and released by the thyroid gland, a small butterfly-shaped endocrine gland located in the front of your neck. It is one of two major hormones produced by the thyroid gland, with the other being triiodothyronine (T3).
Thyroxine plays a crucial role in regulating various metabolic processes in the body, including growth, development, and energy expenditure. Specifically, T4 helps to control the rate at which your body burns calories for energy, regulates protein, fat, and carbohydrate metabolism, and influences the body's sensitivity to other hormones.
T4 is produced by combining iodine and tyrosine, an amino acid found in many foods. Once produced, T4 circulates in the bloodstream and gets converted into its active form, T3, in various tissues throughout the body. Thyroxine has a longer half-life than T3, which means it remains active in the body for a more extended period.
Abnormal levels of thyroxine can lead to various medical conditions, such as hypothyroidism (underactive thyroid) or hyperthyroidism (overactive thyroid). These conditions can cause a range of symptoms, including weight gain or loss, fatigue, mood changes, and changes in heart rate and blood pressure.
Thyrotoxicosis is a medical condition that results from an excess of thyroid hormones in the body, leading to an overactive metabolic state. It can be caused by various factors such as Graves' disease, toxic adenoma, Plummer's disease, or excessive intake of thyroid hormone medication. Symptoms may include rapid heart rate, weight loss, heat intolerance, tremors, and increased sweating, among others. Thyrotoxicosis is not a diagnosis itself but a manifestation of various underlying thyroid disorders. Proper diagnosis and management are crucial to prevent complications and improve quality of life.
Thyrotropin, also known as thyroid-stimulating hormone (TSH), is a hormone secreted by the anterior pituitary gland. Its primary function is to regulate the production and release of thyroxine (T4) and triiodothyronine (T3) hormones from the thyroid gland. Thyrotropin binds to receptors on the surface of thyroid follicular cells, stimulating the uptake of iodide and the synthesis and release of T4 and T3. The secretion of thyrotropin is controlled by the hypothalamic-pituitary-thyroid axis: thyrotropin-releasing hormone (TRH) from the hypothalamus stimulates the release of thyrotropin, while T3 and T4 inhibit its release through a negative feedback mechanism.
Autoantibodies are defined as antibodies that are produced by the immune system and target the body's own cells, tissues, or organs. These antibodies mistakenly identify certain proteins or molecules in the body as foreign invaders and attack them, leading to an autoimmune response. Autoantibodies can be found in various autoimmune diseases such as rheumatoid arthritis, lupus, and thyroiditis. The presence of autoantibodies can also be used as a diagnostic marker for certain conditions.
Iodide peroxidase, also known as iodide:hydrogen peroxide oxidoreductase, is an enzyme that belongs to the family of oxidoreductases. Specifically, it is a peroxidase that uses iodide as its physiological reducing substrate. This enzyme catalyzes the oxidation of iodide by hydrogen peroxide to produce iodine, which plays a crucial role in thyroid hormone biosynthesis.
The systematic name for this enzyme is iodide:hydrogen-peroxide oxidoreductase (iodinating). It is most commonly found in the thyroid gland, where it helps to produce and regulate thyroid hormones by facilitating the iodination of tyrosine residues on thyroglobulin, a protein produced by the thyroid gland.
Iodide peroxidase requires a heme cofactor for its enzymatic activity, which is responsible for the oxidation-reduction reactions it catalyzes. The enzyme's ability to iodinate tyrosine residues on thyroglobulin is essential for the production of triiodothyronine (T3) and thyroxine (T4), two critical hormones that regulate metabolism, growth, and development in mammals.
Thyroid diseases are a group of conditions that affect the function and structure of the thyroid gland, a small butterfly-shaped endocrine gland located in the base of the neck. The thyroid gland produces hormones that regulate many vital functions in the body, including metabolism, growth, and development.
Thyroid diseases can be classified into two main categories: hypothyroidism and hyperthyroidism. Hypothyroidism occurs when the thyroid gland does not produce enough hormones, leading to symptoms such as fatigue, weight gain, cold intolerance, constipation, and depression. Hyperthyroidism, on the other hand, occurs when the thyroid gland produces too much hormone, resulting in symptoms such as weight loss, heat intolerance, rapid heart rate, tremors, and anxiety.
Other common thyroid diseases include:
1. Goiter: an enlargement of the thyroid gland that can be caused by iodine deficiency or autoimmune disorders.
2. Thyroid nodules: abnormal growths on the thyroid gland that can be benign or malignant.
3. Thyroid cancer: a malignant tumor of the thyroid gland that requires medical treatment.
4. Hashimoto's disease: an autoimmune disorder that causes chronic inflammation of the thyroid gland, leading to hypothyroidism.
5. Graves' disease: an autoimmune disorder that causes hyperthyroidism and can also lead to eye problems and skin changes.
Thyroid diseases are diagnosed through a combination of physical examination, medical history, blood tests, and imaging studies such as ultrasound or CT scan. Treatment options depend on the specific type and severity of the disease and may include medication, surgery, or radioactive iodine therapy.
Hypothyroidism is a medical condition where the thyroid gland, which is a small butterfly-shaped gland located in the front of your neck, does not produce enough thyroid hormones. This results in a slowing down of the body's metabolic processes, leading to various symptoms such as fatigue, weight gain, constipation, cold intolerance, dry skin, hair loss, muscle weakness, and depression.
The two main thyroid hormones produced by the thyroid gland are triiodothyronine (T3) and thyroxine (T4). These hormones play crucial roles in regulating various bodily functions, including heart rate, body temperature, and energy levels. In hypothyroidism, the production of these hormones is insufficient, leading to a range of symptoms that can affect multiple organ systems.
Hypothyroidism can be caused by several factors, including autoimmune disorders (such as Hashimoto's thyroiditis), surgical removal of the thyroid gland, radiation therapy for neck cancer, certain medications, and congenital defects. Hypothyroidism is typically diagnosed through blood tests that measure levels of TSH (thyroid-stimulating hormone), T3, and T4. Treatment usually involves taking synthetic thyroid hormones to replace the missing hormones and alleviate symptoms.
Thyroid function tests (TFTs) are a group of blood tests that assess the functioning of the thyroid gland, which is a small butterfly-shaped gland located in the front of the neck. The thyroid gland produces hormones that regulate metabolism, growth, and development in the body.
TFTs typically include the following tests:
1. Thyroid-stimulating hormone (TSH) test: This test measures the level of TSH, a hormone produced by the pituitary gland that regulates the production of thyroid hormones. High levels of TSH may indicate an underactive thyroid gland (hypothyroidism), while low levels may indicate an overactive thyroid gland (hyperthyroidism).
2. Thyroxine (T4) test: This test measures the level of T4, a hormone produced by the thyroid gland. High levels of T4 may indicate hyperthyroidism, while low levels may indicate hypothyroidism.
3. Triiodothyronine (T3) test: This test measures the level of T3, another hormone produced by the thyroid gland. High levels of T3 may indicate hyperthyroidism, while low levels may indicate hypothyroidism.
4. Thyroid peroxidase antibody (TPOAb) test: This test measures the level of TPOAb, an antibody that attacks the thyroid gland and can cause hypothyroidism.
5. Thyroglobulin (Tg) test: This test measures the level of Tg, a protein produced by the thyroid gland. It is used to monitor the treatment of thyroid cancer.
These tests help diagnose and manage various thyroid disorders, including hypothyroidism, hyperthyroidism, thyroiditis, and thyroid cancer.
Goiter is a medical term that refers to an enlarged thyroid gland. The thyroid gland is a small, butterfly-shaped gland located in the front of your neck below the larynx or voice box. It produces hormones that regulate your body's metabolism, growth, and development.
Goiter can vary in size and may be visible as a swelling at the base of the neck. It can be caused by several factors, including iodine deficiency, autoimmune disorders, thyroid cancer, pregnancy, or the use of certain medications. Depending on the underlying cause and the severity of the goiter, treatment options may include medication, surgery, or radioactive iodine therapy.
Immunoglobulins, Thyroid-Stimulating (TSI), are autoantibodies that bind to the thyroid-stimulating hormone receptor (TSHR) on the surface of thyroid cells. These antibodies mimic the action of TSH and stimulate the growth and function of the thyroid gland, leading to excessive production of thyroid hormones. This results in a condition known as Graves' disease, which is characterized by hyperthyroidism, goiter, and sometimes ophthalmopathy (eye problems). The presence and titer of TSIs are used in the diagnosis of Graves' disease.
Iodine is an essential trace element that is necessary for the production of thyroid hormones in the body. These hormones play crucial roles in various bodily functions, including growth and development, metabolism, and brain development during pregnancy and infancy. Iodine can be found in various foods such as seaweed, dairy products, and iodized salt. In a medical context, iodine is also used as an antiseptic to disinfect surfaces, wounds, and skin infections due to its ability to kill bacteria, viruses, and fungi.
A goiter is an abnormal enlargement of the thyroid gland, which is a butterfly-shaped endocrine gland located in the front of the neck. Goiters can be either diffuse (uniformly enlarged) or nodular (lumpy with distinct nodules). Nodular goiter refers to a thyroid gland that has developed one or more discrete lumps or nodules while the remaining tissue is normal or may also be diffusely enlarged.
Nodular goiters can be classified into two types: multinodular goiter and solitary thyroid nodule. Multinodular goiter consists of multiple nodules in the thyroid gland, while a solitary thyroid nodule is an isolated nodule within an otherwise normal or diffusely enlarged thyroid gland.
The majority of nodular goiters are benign and do not cause symptoms. However, some patients may experience signs and symptoms related to compression of nearby structures (such as difficulty swallowing or breathing), hyperthyroidism (overactive thyroid), or hypothyroidism (underactive thyroid). The evaluation of a nodular goiter typically includes a physical examination, imaging studies like ultrasound, and sometimes fine-needle aspiration biopsy to determine the nature of the nodules and assess the risk of malignancy. Treatment options depend on various factors, including the size and number of nodules, the presence of compressive symptoms, and the patient's thyroid function.
Autoimmune diseases are a group of disorders in which the immune system, which normally protects the body from foreign invaders like bacteria and viruses, mistakenly attacks the body's own cells and tissues. This results in inflammation and damage to various organs and tissues in the body.
In autoimmune diseases, the body produces autoantibodies that target its own proteins or cell receptors, leading to their destruction or malfunction. The exact cause of autoimmune diseases is not fully understood, but it is believed that a combination of genetic and environmental factors contribute to their development.
There are over 80 different types of autoimmune diseases, including rheumatoid arthritis, lupus, multiple sclerosis, type 1 diabetes, Hashimoto's thyroiditis, Graves' disease, psoriasis, and inflammatory bowel disease. Symptoms can vary widely depending on the specific autoimmune disease and the organs or tissues affected. Treatment typically involves managing symptoms and suppressing the immune system to prevent further damage.
Thyroid neoplasms refer to abnormal growths or tumors in the thyroid gland, which can be benign (non-cancerous) or malignant (cancerous). These growths can vary in size and may cause a noticeable lump or nodule in the neck. Thyroid neoplasms can also affect the function of the thyroid gland, leading to hormonal imbalances and related symptoms. The exact causes of thyroid neoplasms are not fully understood, but risk factors include radiation exposure, family history, and certain genetic conditions. It is important to note that most thyroid nodules are benign, but a proper medical evaluation is necessary to determine the nature of the growth and develop an appropriate treatment plan.
Thyrotropin receptors (TSHRs) are a type of G protein-coupled receptor found on the surface of cells in the thyroid gland. They bind to thyroid-stimulating hormone (TSH), which is produced and released by the pituitary gland. When TSH binds to the TSHR, it activates a series of intracellular signaling pathways that stimulate the production and release of thyroid hormones, triiodothyronine (T3) and thyroxine (T4). These hormones are important for regulating metabolism, growth, and development in the body. Mutations in the TSHR gene can lead to various thyroid disorders, such as hyperthyroidism or hypothyroidism.
Thyroidectomy is a surgical procedure where all or part of the thyroid gland is removed. The thyroid gland is a butterfly-shaped endocrine gland located in the neck, responsible for producing hormones that regulate metabolism, growth, and development.
There are different types of thyroidectomy procedures, including:
1. Total thyroidectomy: Removal of the entire thyroid gland.
2. Partial (or subtotal) thyroidectomy: Removal of a portion of the thyroid gland.
3. Hemithyroidectomy: Removal of one lobe of the thyroid gland, often performed to treat benign solitary nodules or differentiated thyroid cancer.
Thyroidectomy may be recommended for various reasons, such as treating thyroid nodules, goiter, hyperthyroidism (overactive thyroid), or thyroid cancer. Potential risks and complications of the procedure include bleeding, infection, damage to nearby structures like the parathyroid glands and recurrent laryngeal nerve, and hypoparathyroidism or hypothyroidism due to removal of or damage to the parathyroid glands or thyroid gland, respectively. Close postoperative monitoring and management are essential to minimize these risks and ensure optimal patient outcomes.
Sodium iodide is a chemical compound with the formula NaI. It is a white, crystalline solid that is widely used in medicine, particularly as a radiocontrast agent for imaging procedures such as CT scans and X-rays. Sodium iodide is also used in the treatment of thyroid disorders because it contains iodine, which is an essential nutrient for proper thyroid function.
In medical applications, sodium iodide may be combined with a radioactive isotope such as technetium-99m or iodine-131 to create a radiopharmaceutical that can be used to diagnose or treat various conditions. The radiation emitted by the isotope can be detected by medical imaging equipment, allowing doctors to visualize and assess the function of organs and tissues within the body.
It's important to note that sodium iodide should only be used under the supervision of a qualified healthcare professional, as it may have potential side effects and risks associated with its use.
Hyperthyroidism is a medical condition characterized by an excessive production and release of thyroid hormones from the thyroid gland, leading to an increased metabolic rate in various body systems. The thyroid gland, located in the front of the neck, produces two main thyroid hormones: triiodothyronine (T3) and thyroxine (T4). These hormones play crucial roles in regulating many bodily functions, including heart rate, digestion, energy levels, and mood.
In hyperthyroidism, the elevated levels of T3 and T4 can cause a wide range of symptoms, such as rapid heartbeat, weight loss, heat intolerance, increased appetite, tremors, anxiety, and sleep disturbances. Some common causes of hyperthyroidism include Graves' disease, toxic adenoma, Plummer's disease (toxic multinodular goiter), and thyroiditis. Proper diagnosis and treatment are essential to manage the symptoms and prevent potential complications associated with this condition.
Triiodothyronine (T3) is a thyroid hormone, specifically the active form of thyroid hormone, that plays a critical role in the regulation of metabolism, growth, and development in the human body. It is produced by the thyroid gland through the iodination and coupling of the amino acid tyrosine with three atoms of iodine. T3 is more potent than its precursor, thyroxine (T4), which has four iodine atoms, as T3 binds more strongly to thyroid hormone receptors and accelerates metabolic processes at the cellular level.
In circulation, about 80% of T3 is bound to plasma proteins, while the remaining 20% is unbound or free, allowing it to enter cells and exert its biological effects. The primary functions of T3 include increasing the rate of metabolic reactions, promoting protein synthesis, enhancing sensitivity to catecholamines (e.g., adrenaline), and supporting normal brain development during fetal growth and early infancy. Imbalances in T3 levels can lead to various medical conditions, such as hypothyroidism or hyperthyroidism, which may require clinical intervention and management.
Thyroid hormones are hormones produced and released by the thyroid gland, a small endocrine gland located in the neck that helps regulate metabolism, growth, and development in the human body. The two main thyroid hormones are triiodothyronine (T3) and thyroxine (T4), which contain iodine atoms. These hormones play a crucial role in various bodily functions, including heart rate, body temperature, digestion, and brain development. They help regulate the rate at which your body uses energy, affects how sensitive your body is to other hormones, and plays a vital role in the development and differentiation of all cells of the human body. Thyroid hormone levels are regulated by the hypothalamus and pituitary gland through a feedback mechanism that helps maintain proper balance.
Antithyroid agents are a class of medications that are used to treat hyperthyroidism, a condition in which the thyroid gland produces too much thyroid hormone. These medications work by inhibiting the production of thyroid hormones in the thyroid gland. There are several types of antithyroid agents available, including:
1. Propylthiouracil (PTU): This medication works by blocking the enzyme that is needed to produce thyroid hormones. It also reduces the conversion of thyroxine (T4) to triiodothyronine (T3), another thyroid hormone, in peripheral tissues.
2. Methimazole: This medication works similarly to propylthiouracil by blocking the enzyme that is needed to produce thyroid hormones. However, it does not affect the conversion of T4 to T3 in peripheral tissues.
3. Carbimazole: This medication is converted to methimazole in the body and works similarly to block the production of thyroid hormones.
Antithyroid agents are usually taken orally, and their effects on thyroid hormone production begin within a few hours after ingestion. However, it may take several weeks for patients to notice an improvement in their symptoms. These medications can have side effects, including rash, hives, and joint pain. In rare cases, they can cause liver damage or agranulocytosis, a condition in which the body does not produce enough white blood cells.
It is important to note that antithyroid agents do not cure hyperthyroidism; they only treat the symptoms by reducing thyroid hormone production. Therefore, patients may need to take these medications for several months or even years, depending on their individual circumstances. In some cases, surgery or radioactive iodine therapy may be recommended as alternative treatments for hyperthyroidism.
Puerperal disorders are a group of medical conditions that can affect women during the period following childbirth, also known as the puerperium. The puerperium typically lasts for six to eight weeks after delivery. These disorders can be complications of childbirth or postpartum infections and include:
1. Puerperal fever: This is a febrile illness that occurs during the puerperium, usually caused by a bacterial infection. The most common causative organisms are group A streptococcus, Staphylococcus aureus, and Escherichia coli.
2. Puerperal sepsis: This is a severe form of puerperal fever characterized by the presence of bacteria in the blood (bacteremia) and widespread inflammation throughout the body. It can lead to organ failure and even death if not treated promptly with antibiotics.
3. Puerperal endometritis: This is an infection of the lining of the uterus (endometrium) that occurs during the puerperium. Symptoms may include fever, abdominal pain, and foul-smelling vaginal discharge.
4. Puerperal mastitis: This is an inflammation of the breast tissue that can occur during lactation, often caused by a bacterial infection. It is more common in women who are breastfeeding but can also occur in non-lactating women.
5. Puerperal psychosis: This is a rare but serious mental health disorder that can occur after childbirth. It is characterized by symptoms such as delusions, hallucinations, and disorganized thinking.
6. Puerperal thromboembolism: This is a blood clot that forms during the puerperium, usually in the deep veins of the legs (deep vein thrombosis) or in the lungs (pulmonary embolism). It can be a serious complication of childbirth and requires prompt medical attention.
Overall, puerperal disorders are a significant cause of maternal morbidity and mortality worldwide, particularly in low-income countries where access to healthcare is limited. Prompt diagnosis and treatment are essential for improving outcomes and reducing the risk of long-term complications.
Oxyphil cells, also known as oncocytes, are large granular cells with abundant mitochondria. They can be found in various organs, including the thyroid gland, parathyroid gland, salivary glands, and skin. In the thyroid gland, oxyphil cells are often observed in the context of follicular adenomas or follicular carcinomas, where they can make up a significant portion of the tumor. The exact function of oxyphil cells is not well understood, but it is thought that they may play a role in the production and metabolism of hormones or other substances. In general, the presence of oxyphil cells in a tumor is not considered to be indicative of a specific type or behavior of the tumor, but rather a histological feature that can be observed in a variety of contexts.
A thyroid nodule is a growth or lump that forms within the thyroid gland, a small butterfly-shaped endocrine gland located in the front of your neck. Thyroid nodules can be solid or fluid-filled (cystic) and vary in size. Most thyroid nodules are benign (noncancerous) and do not cause symptoms. However, some thyroid nodules may be cancerous or overproduce hormones, leading to hyperthyroidism. The exact cause of thyroid nodules is not always known, but factors such as iodine deficiency, Hashimoto's disease, and family history can increase the risk of developing them. A healthcare professional typically diagnoses a thyroid nodule through physical examination, imaging tests like ultrasound, or fine-needle aspiration biopsy to determine if further treatment is necessary.
Myxedema is not a term used in modern medicine to describe a specific medical condition. However, historically, it was used to refer to the severe form of hypothyroidism, a condition characterized by an underactive thyroid gland that doesn't produce enough thyroid hormones. In hypothyroidism, various body functions slow down, which can lead to symptoms such as fatigue, weight gain, cold intolerance, constipation, and dry skin.
Myxedema specifically refers to the physical signs of severe hypothyroidism, including swelling (edema) and thickening of the skin, particularly around the face, hands, and feet, as well as a puffy appearance of the face. The term myxedema coma was used to describe a rare but life-threatening complication of long-standing, untreated hypothyroidism, characterized by altered mental status, hypothermia, and other systemic manifestations.
Nowadays, healthcare professionals use more precise medical terminology to describe these conditions, such as hypothyroidism or myxedematous edema, rather than the outdated term myxedema.
Methimazole is an anti-thyroid medication that is primarily used to treat hyperthyroidism, a condition in which the thyroid gland produces excessive amounts of thyroid hormones. It works by inhibiting the enzyme thyroperoxidase, which is essential for the production of thyroid hormones. By blocking this enzyme, methimazole reduces the amount of thyroid hormones produced by the thyroid gland, helping to restore normal thyroid function.
Methimazole is available in oral tablet form and is typically taken two to three times a day. Common side effects of methimazole include nausea, vomiting, skin rashes, and joint pain. In rare cases, it can cause more serious side effects such as liver damage or agranulocytosis (a severe decrease in white blood cell count).
It is important to note that methimazole should only be used under the close supervision of a healthcare provider, as regular monitoring of thyroid function and potential side effects is necessary. Additionally, it may take several weeks or months of treatment with methimazole before thyroid function returns to normal.
Thymectomy is a surgical procedure that involves the removal of the thymus gland. The thymus gland is a part of the immune system located in the upper chest, behind the sternum (breastbone), and above the heart. It is responsible for producing white blood cells called T-lymphocytes, which help fight infections.
Thymectomy is often performed as a treatment option for patients with certain medical conditions, such as:
* Myasthenia gravis: an autoimmune disorder that causes muscle weakness and fatigue. In some cases, the thymus gland may contain abnormal cells that contribute to the development of myasthenia gravis. Removing the thymus gland can help improve symptoms in some patients with this condition.
* Thymomas: tumors that develop in the thymus gland. While most thymomas are benign (non-cancerous), some can be malignant (cancerous) and may require surgical removal.
* Myasthenic syndrome: a group of disorders characterized by muscle weakness and fatigue, similar to myasthenia gravis. In some cases, the thymus gland may be abnormal and contribute to the development of these conditions. Removing the thymus gland can help improve symptoms in some patients.
Thymectomy can be performed using various surgical approaches, including open surgery (through a large incision in the chest), video-assisted thoracoscopic surgery (VATS, using small incisions and a camera to guide the procedure), or robotic-assisted surgery (using a robot to perform the procedure through small incisions). The choice of surgical approach depends on several factors, including the size and location of the thymus gland, the patient's overall health, and the surgeon's expertise.
"CBA" is an abbreviation for a specific strain of inbred mice that were developed at the Cancer Research Institute in London. The "Inbred CBA" mice are genetically identical individuals within the same strain, due to many generations of brother-sister matings. This results in a homozygous population, making them valuable tools for research because they reduce variability and increase reproducibility in experimental outcomes.
The CBA strain is known for its susceptibility to certain diseases, such as autoimmune disorders and cancer, which makes it a popular choice for researchers studying those conditions. Additionally, the CBA strain has been widely used in studies related to transplantation immunology, infectious diseases, and genetic research.
It's important to note that while "Inbred CBA" mice are a well-established and useful tool in biomedical research, they represent only one of many inbred strains available for scientific investigation. Each strain has its own unique characteristics and advantages, depending on the specific research question being asked.
I'm sorry for any confusion, but "Rats, Inbred BB" is not a widely recognized medical term or abbreviation in human or veterinary medicine. The term "inbred" is used in genetics to describe an organism that has resulted from many generations of mating between closely related individuals, which can lead to a higher incidence of homozygosity (the same allele inherited from both parents) and expression of recessive traits.
The "BB" strain could refer to a specific inbred rat strain, but without more context, it's difficult to provide a precise definition. The BB Wistar rat strain is sometimes used in research, and it has been used as a model for studying various medical conditions such as diabetes and hypertension.
If you are looking for information about a specific scientific study or medical condition related to an "Inbred BB" rat strain, I would be happy to help you if you could provide more context or details.
Carcinoma, papillary is a type of cancer that begins in the cells that line the glandular structures or the lining of organs. In a papillary carcinoma, the cancerous cells grow and form small finger-like projections, called papillae, within the tumor. This type of cancer most commonly occurs in the thyroid gland, but can also be found in other organs such as the lung, breast, and kidney. Papillary carcinoma of the thyroid gland is usually slow-growing and has a good prognosis, especially when it is diagnosed at an early stage.
Autoimmunity is a medical condition in which the body's immune system mistakenly attacks and destroys healthy tissues within the body. In normal function, the immune system recognizes and fights off foreign substances such as bacteria, viruses, and toxins. However, when autoimmunity occurs, the immune system identifies self-molecules or tissues as foreign and produces an immune response against them.
This misguided response can lead to chronic inflammation, tissue damage, and impaired organ function. Autoimmune diseases can affect various parts of the body, including the joints, skin, glands, muscles, and blood vessels. Some common examples of autoimmune diseases are rheumatoid arthritis, lupus, multiple sclerosis, type 1 diabetes, Hashimoto's thyroiditis, and Graves' disease.
The exact cause of autoimmunity is not fully understood, but it is believed to involve a combination of genetic, environmental, and lifestyle factors that trigger an abnormal immune response in susceptible individuals. Treatment for autoimmune diseases typically involves managing symptoms, reducing inflammation, and suppressing the immune system's overactive response using medications such as corticosteroids, immunosuppressants, and biologics.
Polyendocrinopathies, autoimmune refers to a group of disorders that involve malfunction of multiple endocrine glands, caused by the immune system mistakenly attacking and damaging these glands. The endocrine glands are responsible for producing hormones that regulate various functions in the body.
There are several types of autoimmune polyendocrinopathies, including:
1. Autoimmune Polyendocrine Syndrome Type 1 (APS-1): Also known as Autoimmune Polyglandular Syndrome Type 1 or APECED, this is a rare inherited disorder that typically affects multiple endocrine glands and other organs. It is caused by mutations in the autoimmune regulator (AIRE) gene.
2. Autoimmune Polyendocrine Syndrome Type 2 (APS-2): Also known as Schmidt's syndrome, this disorder typically involves the adrenal glands, thyroid gland, and/or insulin-producing cells in the pancreas. It is more common than APS-1 and often affects middle-aged women.
3. Autoimmune Polyendocrine Syndrome Type 3 (APS-3): This disorder involves the presence of autoimmune Addison's disease, with or without other autoimmune disorders such as thyroid disease, type 1 diabetes, or vitiligo.
4. Autoimmune Polyendocrine Syndrome Type 4 (APS-4): This is a catch-all category for individuals who have multiple autoimmune endocrine disorders that do not fit into the other types of APS.
Symptoms of autoimmune polyendocrinopathies can vary widely depending on which glands are affected and the severity of the damage. Treatment typically involves replacing the hormones that are no longer being produced in sufficient quantities, as well as managing any underlying immune system dysfunction.
Carbimazole is an antithyroid medication that is primarily used to manage hyperthyroidism, a condition characterized by an overactive thyroid gland that produces excessive amounts of thyroid hormones. The drug works by inhibiting the enzyme responsible for producing these hormones, thereby reducing their levels in the body and alleviating symptoms associated with the disorder.
Hyperthyroidism can manifest as various signs and symptoms, including rapid heartbeat, weight loss, heat intolerance, tremors, anxiety, and sleep disturbances. Common causes of hyperthyroidism include Graves' disease, toxic adenoma, and thyroiditis.
Carbimazole is a prodrug that gets converted to its active metabolite, methimazole, in the liver. Methimazole inhibits the activity of thyroperoxidase, an enzyme involved in the synthesis of thyroid hormones triiodothyronine (T3) and thyroxine (T4). By blocking this enzyme, carbimazole reduces the production of T3 and T4, ultimately helping to control hyperthyroidism.
The medication is typically administered orally in tablet form, with dosages varying depending on individual patient needs and response to treatment. Common side effects of carbimazole include gastrointestinal disturbances such as nausea, vomiting, and diarrhea. Rare but severe adverse reactions may include agranulocytosis (a severe decrease in white blood cells), aplastic anemia (a condition where the bone marrow fails to produce sufficient numbers of blood cells), and hepatotoxicity (liver damage).
Patients taking carbimazole should be closely monitored for signs of adverse reactions, and regular blood tests are necessary to assess thyroid hormone levels and potential side effects. Pregnant women should avoid using carbimazole due to the risk of birth defects in the developing fetus. In such cases, alternative antithyroid medications like propylthiouracil may be prescribed instead.
In summary, carbimazole is an antithyroid medication used primarily for managing hyperthyroidism by inhibiting thyroperoxidase and reducing the production of thyroid hormones T3 and T4. While effective, it carries potential risks and side effects that necessitate close monitoring during treatment.
Sodium Pertechnetate Tc 99m is a radioactive pharmaceutical preparation used in medical diagnostic imaging. It is a technetium-99m radiopharmaceutical, where technetium-99m is a metastable nuclear isomer of technetium-99, which emits gamma rays and has a half-life of 6 hours. Sodium Pertechnetate Tc 99m is used as a contrast agent in various diagnostic procedures, such as imaging of the thyroid, salivary glands, or the brain, to evaluate conditions like inflammation, tumors, or abnormalities in blood flow. It is typically administered intravenously, and its short half-life ensures that the radiation exposure is limited.
A fine-needle biopsy (FNB) is a medical procedure in which a thin, hollow needle is used to obtain a sample of cells or tissue from a suspicious or abnormal area in the body, such as a lump or mass. The needle is typically smaller than that used in a core needle biopsy, and it is guided into place using imaging techniques such as ultrasound, CT scan, or MRI.
The sample obtained during an FNB can be used to diagnose various medical conditions, including cancer, infection, or inflammation. The procedure is generally considered safe and well-tolerated, with minimal risks of complications such as bleeding, infection, or discomfort. However, the accuracy of the diagnosis depends on the skill and experience of the healthcare provider performing the biopsy, as well as the adequacy of the sample obtained.
Overall, FNB is a valuable diagnostic tool that can help healthcare providers make informed decisions about treatment options and improve patient outcomes.
Addison disease, also known as primary adrenal insufficiency or hypocortisolism, is a rare endocrine disorder characterized by the dysfunction and underproduction of hormones produced by the adrenal glands, specifically cortisol and aldosterone. The adrenal glands are located on top of the kidneys and play a crucial role in regulating various bodily functions such as metabolism, blood pressure, stress response, and immune system function.
The primary cause of Addison disease is the destruction of more than 90% of the adrenal cortex, which is the outer layer of the adrenal glands responsible for hormone production. This damage can be due to an autoimmune disorder where the body's immune system mistakenly attacks and destroys the adrenal gland tissue, infections such as tuberculosis or HIV, cancer, genetic disorders, or certain medications.
The symptoms of Addison disease often develop gradually and may include fatigue, weakness, weight loss, decreased appetite, low blood pressure, darkening of the skin, and mood changes. In some cases, an acute crisis known as acute adrenal insufficiency or Addisonian crisis can occur, which is a medical emergency characterized by sudden and severe symptoms such as extreme weakness, confusion, dehydration, vomiting, diarrhea, low blood sugar, and coma.
Diagnosis of Addison disease typically involves blood tests to measure hormone levels, imaging studies such as CT scans or MRIs to assess the adrenal glands' size and structure, and stimulation tests to evaluate the adrenal glands' function. Treatment usually involves replacing the missing hormones with medications such as hydrocortisone, fludrocortisone, and sometimes mineralocorticoids. With proper treatment and management, individuals with Addison disease can lead normal and productive lives.
Iodine radioisotopes are radioactive isotopes of the element iodine, which decays and emits radiation in the form of gamma rays. Some commonly used iodine radioisotopes include I-123, I-125, I-131. These radioisotopes have various medical applications such as in diagnostic imaging, therapy for thyroid disorders, and cancer treatment.
For example, I-131 is commonly used to treat hyperthyroidism and differentiated thyroid cancer due to its ability to destroy thyroid tissue. On the other hand, I-123 is often used in nuclear medicine scans of the thyroid gland because it emits gamma rays that can be detected by a gamma camera, allowing for detailed images of the gland's structure and function.
It is important to note that handling and administering radioisotopes require specialized training and safety precautions due to their radiation-emitting properties.
Inbred NOD (Nonobese Diabetic) mice are a strain of laboratory mice that are genetically predisposed to develop autoimmune diabetes. This strain was originally developed in Japan and has been widely used as an animal model for studying type 1 diabetes and its complications.
NOD mice typically develop diabetes spontaneously at around 12-14 weeks of age, although the onset and severity of the disease can vary between individual mice. The disease is caused by a breakdown in immune tolerance, leading to an autoimmune attack on the insulin-producing beta cells of the pancreas.
Inbred NOD mice are highly valuable for research purposes because they exhibit many of the same genetic and immunological features as human patients with type 1 diabetes. By studying these mice, researchers can gain insights into the underlying mechanisms of the disease and develop new treatments and therapies.
Antibodies are proteins produced by the immune system in response to the presence of a foreign substance, such as a bacterium or virus. They are capable of identifying and binding to specific antigens (foreign substances) on the surface of these invaders, marking them for destruction by other immune cells. Antibodies are also known as immunoglobulins and come in several different types, including IgA, IgD, IgE, IgG, and IgM, each with a unique function in the immune response. They are composed of four polypeptide chains, two heavy chains and two light chains, that are held together by disulfide bonds. The variable regions of the heavy and light chains form the antigen-binding site, which is specific to a particular antigen.
Sweet syndrome, also known as acute febrile neutrophilic dermatosis, is a skin condition characterized by the rapid onset of painful, red, and swollen skin lesions. The lesions are often accompanied by fever and elevated white blood cell count, particularly an increase in neutrophils.
The medical definition of Sweet syndrome includes the following criteria:
1. Abrupt onset of painful, erythematous (red), and edematous (swollen) papules, plaques, or nodules.
2. Fever greater than 38°C (100.4°F).
3. Leukocytosis with a predominance of neutrophils in the peripheral blood.
4. Histopathological evidence of a dense dermal infiltrate of neutrophils without evidence of vasculitis.
5. Rapid response to systemic corticosteroids.
Sweet syndrome can be associated with various medical conditions, such as infections, malignancies, and inflammatory diseases, or it can occur without an identifiable underlying cause (idiopathic).
Endocrine tuberculosis (TB) is a form of extrapulmonary tuberculosis that involves the endocrine glands, such as the thyroid, pituitary, and adrenal glands. The infection can cause inflammation, granulomatous lesions, and tissue damage in these glands, leading to hormonal imbalances and various clinical manifestations.
Tuberculosis bacilli (Mycobacterium tuberculosis) reach the endocrine glands through hematogenous spread from a primary or secondary focus, usually in the lungs. The most common form of endocrine TB is adrenal TB, which can lead to adrenal insufficiency due to destruction of the adrenal cortex. Thyroid TB is rare and typically presents as a cold abscess or a thyroid mass. Pituitary TB is also uncommon but can cause hypopituitarism and visual impairment due to compression of the optic chiasm.
Diagnosis of endocrine TB often involves imaging studies, such as CT or MRI scans, hormonal assessments, and microbiological or histopathological examination of tissue samples obtained through biopsy. Treatment typically consists of a standard anti-tuberculous chemotherapy regimen, which may need to be adjusted based on the patient's hormonal status and clinical response.
Vocal cord paralysis is a medical condition characterized by the inability of one or both vocal cords to move or function properly due to nerve damage or disruption. The vocal cords are two bands of muscle located in the larynx (voice box) that vibrate to produce sound during speech, singing, and breathing. When the nerves that control the vocal cord movements are damaged or not functioning correctly, the vocal cords may become paralyzed or weakened, leading to voice changes, breathing difficulties, and other symptoms.
The causes of vocal cord paralysis can vary, including neurological disorders, trauma, tumors, surgery, or infections. The diagnosis typically involves a physical examination, including a laryngoscopy, to assess the movement and function of the vocal cords. Treatment options may include voice therapy, surgical procedures, or other interventions to improve voice quality and breathing functions.
Retroperitoneal fibrosis (RPF) is a rare and progressive condition characterized by the abnormal growth of fibrous tissue in the retroperitoneal space, which is the area behind the peritoneum (the lining that covers the abdominal cavity). This fibrous tissue can encase and compress vital structures such as the ureters, blood vessels, and nerves, leading to various symptoms.
RPF can be idiopathic (without a known cause) or secondary to other conditions like infections, malignancies, autoimmune diseases, or medications. The exact pathogenesis of RPF is not fully understood, but it's believed that an abnormal immune response and inflammation play significant roles in its development.
Symptoms of RPF may include:
1. Flank pain or back pain
2. Renal insufficiency or kidney failure due to ureteral compression
3. Hydronephrosis (dilatation of the renal pelvis and calyces)
4. Deep vein thrombosis (DVT) or pulmonary embolism (PE) due to vascular compression
5. Neurological symptoms due to nerve compression
6. Weight loss, fatigue, and fever (in some cases)
Diagnosis of RPF typically involves imaging studies such as computed tomography (CT) scans or magnetic resonance imaging (MRI), along with laboratory tests and sometimes biopsy for confirmation. Treatment options depend on the underlying cause but generally involve immunosuppressive medications, corticosteroids, and surgical intervention in severe cases.
The pyriform (or piriform) sinus refers to a pair of narrow, funnel-shaped spaces located at the base of the tongue, near the epiglottis, in the upper part of the larynx. These sinuses are lined with respiratory epithelium and are part of the digestive tract, as they connect to the esophagus through the upper esophageal sphincter. The pyriform sinuses play a role in the initial stages of swallowing, directing food and liquids into the esophagus. They can also serve as a potential site for the entrapment and growth of foreign bodies or abnormal tissue, such as in the case of a pyriform sinus fistula or diverticulum.
Vitiligo is a medical condition characterized by the loss of pigmentation in patches of skin, resulting in irregular white depigmented areas. It's caused by the destruction of melanocytes, the cells responsible for producing melanin, which gives our skin its color. The exact cause of vitiligo is not fully understood, but it's thought to be an autoimmune disorder where the immune system mistakenly attacks and destroys melanocytes. It can affect people of any age, gender, or ethnicity, although it may be more noticeable in people with darker skin tones. The progression of vitiligo is unpredictable and can vary from person to person. Treatment options include topical creams, light therapy, oral medications, and surgical procedures, but the effectiveness of these treatments varies depending on the individual case.
Immunoglobulin G (IgG) is a type of antibody, which is a protective protein produced by the immune system in response to foreign substances like bacteria or viruses. IgG is the most abundant type of antibody in human blood, making up about 75-80% of all antibodies. It is found in all body fluids and plays a crucial role in fighting infections caused by bacteria, viruses, and toxins.
IgG has several important functions:
1. Neutralization: IgG can bind to the surface of bacteria or viruses, preventing them from attaching to and infecting human cells.
2. Opsonization: IgG coats the surface of pathogens, making them more recognizable and easier for immune cells like neutrophils and macrophages to phagocytose (engulf and destroy) them.
3. Complement activation: IgG can activate the complement system, a group of proteins that work together to help eliminate pathogens from the body. Activation of the complement system leads to the formation of the membrane attack complex, which creates holes in the cell membranes of bacteria, leading to their lysis (destruction).
4. Antibody-dependent cellular cytotoxicity (ADCC): IgG can bind to immune cells like natural killer (NK) cells and trigger them to release substances that cause target cells (such as virus-infected or cancerous cells) to undergo apoptosis (programmed cell death).
5. Immune complex formation: IgG can form immune complexes with antigens, which can then be removed from the body through various mechanisms, such as phagocytosis by immune cells or excretion in urine.
IgG is a critical component of adaptive immunity and provides long-lasting protection against reinfection with many pathogens. It has four subclasses (IgG1, IgG2, IgG3, and IgG4) that differ in their structure, function, and distribution in the body.
I'm sorry for any confusion, but "Sulfanilic Acids" is not a recognized medical term or a specific medical condition. Sulfanilic acid is a chemical compound with the formula H2SO3NCH2COOH. It is used in various industrial applications such as dye and drug synthesis, but it is not a term that would be commonly used in medical contexts.
If you have any questions related to medical topics or conditions, I'd be happy to help! Please provide more information so I can give you a relevant and accurate response.
A granuloma is a small, nodular inflammatory lesion that occurs in various tissues in response to chronic infection, foreign body reaction, or autoimmune conditions. Histologically, it is characterized by the presence of epithelioid macrophages, which are specialized immune cells with enlarged nuclei and abundant cytoplasm, often arranged in a palisading pattern around a central area containing necrotic debris, microorganisms, or foreign material.
Granulomas can be found in various medical conditions such as tuberculosis, sarcoidosis, fungal infections, and certain autoimmune disorders like Crohn's disease. The formation of granulomas is a complex process involving both innate and adaptive immune responses, which aim to contain and eliminate the offending agent while minimizing tissue damage.
Autoantigens are substances that are typically found in an individual's own body, but can stimulate an immune response because they are recognized as foreign by the body's own immune system. In autoimmune diseases, the immune system mistakenly attacks and damages healthy tissues and organs because it recognizes some of their components as autoantigens. These autoantigens can be proteins, DNA, or other molecules that are normally present in the body but have become altered or exposed due to various factors such as infection, genetics, or environmental triggers. The immune system then produces antibodies and activates immune cells to attack these autoantigens, leading to tissue damage and inflammation.
Thyrotropin-Releasing Hormone (TRH) is a tripeptide hormone that is produced and released by the hypothalamus in the brain. Its main function is to regulate the release of thyroid-stimulating hormone (TSH) from the anterior pituitary gland. TRH acts on the pituitary gland to stimulate the synthesis and secretion of TSH, which then stimulates the thyroid gland to produce and release thyroid hormones (triiodothyronine (T3) and thyroxine (T4)) into the bloodstream.
TRH is a tripeptide amino acid sequence with the structure of pGlu-His-Pro-NH2, and it is synthesized as a larger precursor molecule called preprothyrotropin-releasing hormone (preproTRH) in the hypothalamus. PreproTRH undergoes post-translational processing to produce TRH, which is then stored in secretory vesicles and released into the hypophyseal portal system, where it travels to the anterior pituitary gland and binds to TRH receptors on thyrotroph cells.
In addition to its role in regulating TSH release, TRH has been shown to have other physiological functions, including modulation of feeding behavior, body temperature, and neurotransmitter release. Dysregulation of the TRH-TSH axis can lead to various thyroid disorders, such as hypothyroidism or hyperthyroidism.
Adenocarcinoma, papillary is a type of cancer that begins in the glandular cells and grows in a finger-like projection (called a papilla). This type of cancer can occur in various organs, including the lungs, pancreas, thyroid, and female reproductive system. The prognosis and treatment options for papillary adenocarcinoma depend on several factors, such as the location and stage of the tumor, as well as the patient's overall health. It is important to consult with a healthcare professional for an accurate diagnosis and personalized treatment plan.
Graves' ophthalmopathy, also known as Graves' eye disease or thyroid eye disease, is an autoimmune condition that affects the eyes. It often occurs in individuals with Graves' disease, an autoimmune disorder that causes hyperthyroidism (overactive thyroid gland). However, it can also occur in people without Graves' disease.
In Graves' ophthalmopathy, the immune system attacks the tissue behind the eyes, causing inflammation and enlargement of the muscles, fatty tissue, and connective tissue within the orbit (eye socket). This leads to symptoms such as:
1. Protrusion or bulging of the eyes (exophthalmos)
2. Redness and swelling of the eyelids
3. Double vision (diplopia) due to restricted eye movement
4. Pain and discomfort, especially when looking up, down, or sideways
5. Light sensitivity (photophobia)
6. Tearing and dryness in the eyes
7. Vision loss in severe cases
The treatment for Graves' ophthalmopathy depends on the severity of the symptoms and may include medications to manage inflammation, eye drops or ointments for dryness, prisms to correct double vision, or surgery for severe cases.
HLA-DR3 antigen is a type of human leukocyte antigen (HLA) class II histocompatibility antigen. HLAs are proteins found on the surface of cells that help the immune system distinguish between the body's own cells and foreign substances. The HLA-DR3 antigen is encoded by the DRB1*03:01 gene and is commonly found in individuals with certain autoimmune diseases, such as rheumatoid arthritis, type 1 diabetes, and celiac disease.
The HLA-DR3 antigen plays a role in presenting pieces of proteins (peptides) to CD4+ T cells, which are a type of white blood cell that helps coordinate the immune response. The presentation of specific peptides by the HLA-DR3 antigen can lead to an abnormal immune response in some individuals, resulting in the development of autoimmune diseases.
It's important to note that having the HLA-DR3 antigen does not guarantee that a person will develop an autoimmune disease, as other genetic and environmental factors also play a role.
Diabetes Mellitus, Type 1 is a chronic autoimmune disease characterized by the destruction of insulin-producing beta cells in the pancreas, leading to an absolute deficiency of insulin. This results in an inability to regulate blood glucose levels, causing hyperglycemia (high blood sugar). Type 1 diabetes typically presents in childhood or early adulthood, although it can develop at any age. It is usually managed with regular insulin injections or the use of an insulin pump, along with monitoring of blood glucose levels and adjustments to diet and physical activity. Uncontrolled type 1 diabetes can lead to serious complications such as kidney damage, nerve damage, blindness, and cardiovascular disease.
HLA-B35 antigen is a type of human leukocyte antigen (HLA) class I histocompatibility antigen. HLAs are proteins that play an important role in the body's immune system. They are found on the surface of cells and help the immune system distinguish between the body's own cells and foreign substances such as viruses and bacteria.
The HLA-B35 antigen is one of many different types of HLA-B antigens, which are located on chromosome 6 in the major histocompatibility complex (MHC) region. The HLA-B35 antigen is encoded by the HLA-B gene and is expressed as a transmembrane glycoprotein.
The HLA-B35 antigen is found in approximately 15-20% of the Caucasian population, but it is less common in other populations. It has been associated with an increased risk of developing certain diseases, including HIV infection and some types of cancer. However, the presence of the HLA-B35 antigen does not necessarily mean that a person will develop these diseases, as many other factors are also involved.
Endemic goiter refers to a condition of abnormal enlargement of the thyroid gland that is prevalent in a particular geographic area due to deficiency of iodine in the diet or drinking water. The lack of iodine leads to decreased production of thyroid hormones, which in turn stimulates the thyroid gland to grow and attempt to increase hormone production. This results in the visible enlargement of the thyroid gland, known as a goiter. Endemic goiter is preventable through iodine supplementation in the diet or through iodized salt.
Lymphocytes are a type of white blood cell that is an essential part of the immune system. They are responsible for recognizing and responding to potentially harmful substances such as viruses, bacteria, and other foreign invaders. There are two main types of lymphocytes: B-lymphocytes (B-cells) and T-lymphocytes (T-cells).
B-lymphocytes produce antibodies, which are proteins that help to neutralize or destroy foreign substances. When a B-cell encounters a foreign substance, it becomes activated and begins to divide and differentiate into plasma cells, which produce and secrete large amounts of antibodies. These antibodies bind to the foreign substance, marking it for destruction by other immune cells.
T-lymphocytes, on the other hand, are involved in cell-mediated immunity. They directly attack and destroy infected cells or cancerous cells. T-cells can also help to regulate the immune response by producing chemical signals that activate or inhibit other immune cells.
Lymphocytes are produced in the bone marrow and mature in either the bone marrow (B-cells) or the thymus gland (T-cells). They circulate throughout the body in the blood and lymphatic system, where they can be found in high concentrations in lymph nodes, the spleen, and other lymphoid organs.
Abnormalities in the number or function of lymphocytes can lead to a variety of immune-related disorders, including immunodeficiency diseases, autoimmune disorders, and cancer.
Pharyngeal diseases refer to conditions that affect the pharynx, which is the part of the throat that lies behind the nasal cavity and mouth, and above the esophagus and larynx. The pharynx plays a crucial role in swallowing, speaking, and breathing. Pharyngeal diseases can cause symptoms such as sore throat, difficulty swallowing, pain during swallowing, swollen lymph nodes, and earaches.
Some common pharyngeal diseases include:
1. Pharyngitis: Inflammation of the pharynx, often caused by a viral or bacterial infection.
2. Tonsillitis: Inflammation of the tonsils, which are two masses of lymphoid tissue located on either side of the back of the throat.
3. Epiglottitis: Inflammation of the epiglottis, a flap of cartilage that covers the windpipe during swallowing to prevent food and liquids from entering the lungs.
4. Abscesses: A collection of pus in the pharynx caused by a bacterial infection.
5. Cancer: Malignant tumors that can develop in the pharynx, often caused by smoking or heavy alcohol use.
6. Dysphagia: Difficulty swallowing due to nerve damage, muscle weakness, or structural abnormalities in the pharynx.
7. Stridor: Noisy breathing caused by a narrowed or obstructed airway in the pharynx.
Treatment for pharyngeal diseases depends on the underlying cause and may include antibiotics, pain relievers, surgery, or radiation therapy.
Sulfadimethoxine is an antimicrobial agent, specifically a sulfonamide. It is defined as a synthetic antibacterial drug that contains the sulfanilamide nucleus and is used to treat various bacterial infections in both humans and animals. In human medicine, it is used to treat urinary tract infections, bronchitis, and traveler's diarrhea. In veterinary medicine, it is commonly used to treat coccidiosis in animals such as poultry, cattle, and pets.
The drug works by inhibiting the bacterial synthesis of folic acid, which is essential for bacterial growth. It is usually administered orally and is available in various forms, including tablets, capsules, and powder for suspension. As with any medication, it should be used under the guidance of a healthcare professional to ensure its safe and effective use.
Prednisolone is a synthetic glucocorticoid drug, which is a class of steroid hormones. It is commonly used in the treatment of various inflammatory and autoimmune conditions due to its potent anti-inflammatory and immunosuppressive effects. Prednisolone works by binding to specific receptors in cells, leading to changes in gene expression that reduce the production of substances involved in inflammation, such as cytokines and prostaglandins.
Prednisolone is available in various forms, including tablets, syrups, and injectable solutions. It can be used to treat a wide range of medical conditions, including asthma, rheumatoid arthritis, inflammatory bowel disease, allergies, skin conditions, and certain types of cancer.
Like other steroid medications, prednisolone can have significant side effects if used in high doses or for long periods of time. These may include weight gain, mood changes, increased risk of infections, osteoporosis, diabetes, and adrenal suppression. As a result, the use of prednisolone should be closely monitored by a healthcare professional to ensure that its benefits outweigh its risks.
Freund's adjuvant is not a medical condition but a substance used in laboratory research to enhance the body's immune response to an antigen or vaccine. It is named after its developer, Jules T. Freund.
There are two types of Freund's adjuvants: complete and incomplete. Freund's complete adjuvant (FCA) contains killed Mycobacterium tuberculosis bacteria, which causes a strong inflammatory response when injected into the body. This makes it an effective adjuvant for experimental vaccines, as it helps to stimulate the immune system and promote a stronger and longer-lasting immune response.
Freund's incomplete adjuvant (FIA) is similar to FCA but does not contain Mycobacterium tuberculosis. It is less potent than FCA but still useful for boosting the immune response to certain antigens.
It is important to note that Freund's adjuvants are not used in human vaccines due to their potential to cause adverse reactions, including granulomas and other inflammatory responses. They are primarily used in laboratory research with animals.
Pituitary diseases refer to a group of conditions that affect the pituitary gland, a small endocrine gland located at the base of the brain. The pituitary gland is responsible for producing and secreting several important hormones that regulate various bodily functions, including growth and development, metabolism, stress response, and reproduction.
Pituitary diseases can be classified into two main categories:
1. Pituitary tumors: These are abnormal growths in or around the pituitary gland that can affect its function. Pituitary tumors can be benign (non-cancerous) or malignant (cancerous), and they can vary in size. Some pituitary tumors produce excess hormones, leading to a variety of symptoms, while others may not produce any hormones but can still cause problems by compressing nearby structures in the brain.
2. Pituitary gland dysfunction: This refers to conditions that affect the normal function of the pituitary gland without the presence of a tumor. Examples include hypopituitarism, which is a condition characterized by decreased production of one or more pituitary hormones, and Sheehan's syndrome, which occurs when the pituitary gland is damaged due to severe blood loss during childbirth.
Symptoms of pituitary diseases can vary widely depending on the specific condition and the hormones that are affected. Treatment options may include surgery, radiation therapy, medication, or a combination of these approaches.
