Excessive amount of sodium in the blood. (Dorland, 27th ed)
Benign and malignant tumors of the HYPOTHALAMUS. Pilocytic astrocytomas and hamartomas are relatively frequent histologic types. Neoplasms of the hypothalamus frequently originate from adjacent structures, including the OPTIC CHIASM, optic nerve (see OPTIC NERVE NEOPLASMS), and pituitary gland (see PITUITARY NEOPLASMS). Relatively frequent clinical manifestations include visual loss, developmental delay, macrocephaly, and precocious puberty.

Increased insensible water loss in newborn infants nursed under radiant heaters. (1/165)

Urine osmolality was studied in 38 babies nursed in conventional incubators or cots and 18 nursed under an overhead radiant heat shield. Among 50 babies receiving a similar fluid intake in the first 48 hours of life mean urinary osmolality was significantly higher in the radiant heater group. In babies weighing less than 1500 g a trend towards higher urinary osmolalities was recorded in those nursed under radiant heaters even though they had received amost double the fluid intake of the incubator group. Severe hypernatraemia occurred in four of the five babies weighing less than 1000 g who were nursed under radiant heaters but in none of the seven babies of similar birth weight nursed in incubators. These findings are consistent with previous observations of an increase in insensible water loss in babies nursed under radiant heaters and emphasise the importance of providing enough extra water for these infants and the need for close monitoring of their fluid balance. The latter may be done at the bedside by measuring urinary specific gravity with a hand refractometer.  (+info)

Acute and chronic dose-response relationships for angiotensin, aldosterone, and arterial pressure at varying levels of sodium intake. (2/165)

We examined the acute and chronic dose-response relationships between intravenously infused angiotensin II (A II) and the resulting changes in arterial pressure and plasma aldosterone concentration at varying levels of sodium intake. Sequential analysis of plasma aldosterone at each A II infusion rate resulted in an acute dose-related increase in plasma aldosterone which was markedly attenuated after the first 24 hours of infusion, the final level being directly related to the dose of A II and inversely related to sodium intake. A II infused at 5,15, and 23 ng/kg per min was associated with an initial increase (2nd to 8th hour) in plasma aldosterone to 2,6, and 9 times control values, respectively, in dogs receiving 40 mEq Na+/day. But, after the 1st day, aldosterone averaged only 1, 1.7, and 3 times control values for the next 2 weeks at the same rates of A II infusion. Dogs receiving 120 mEq Na+/day during A II infusion exhibited only a transient increase in plasma aldosterone during the 1st day. Sustained hypertension developed over a period of a week at all doses of A II at normal and high sodium intake, but did not occur at any dose of A II in sodium-depleted dogs. Increasing sodium intake from 40 to 120 mEq/day resulted in higher levels of hypertension, 125% compared to 140% of ocntrol values for dogs infused with A II, 5.0 ng/kg per min. We conclude that primary angiotensin-induced hypertension need not be associated with increased levels of plasma aldosterone, which appears to remain elevated only with amounts of A II greater than those required to sustain a significant degree of hypertension.  (+info)

Hypercalcemia accompanied by hypothalamic hypopituitarism, central diabetes inspidus and hyperthyroidism. (3/165)

We present here a case of prominent hypercalcemia accompanied by hypothalamic tumor and Graves' disease. A 24-year-old man with hypothalamic tumor showed hypopituitarism, central diabetes inspidus (DI) and hyperthyroidism. Nausea, loss of thirst and appetite, and general fatigue were found with the unveiling of hypercalcemia and hypernatremia. Parathyroid hormone (PTH) and 1alpha-dihydroxyvitamin D levels were suppressed with a normal range of PTH-related protein values. One-desamino-(8-D-arginine)-vasopressin (DDAVP) and half-saline administration normalized hypernatremia, while hypercalcemia was still sustained. Administration of cortisone acetate and thiamazole reduced the elevated serum Ca level. In the present case, concurrent hyperthyroidism was assumed to accelerate skeletal mobilization of calcium into the circulation. Hypocortisolism and central DI was also considered to contribute, to some extent, to the hypercalcemia through renal handling of Ca.  (+info)

Neonatal hypernatremic dehydration associated with breast-feeding malnutrition: a retrospective survey. (4/165)

BACKGROUND: Hypernatremic dehydration in neonates is a potentially devastating condition. Recent reports have identified breast-feeding malnutrition as a key factor in its pathophysiology. METHODS: Using a theoretical framework for breast-feeding kinetics, a retrospective chart review of all neonates less than 28 days of age who were seen at either British Columbia's Children's Hospital or the Vancouver Breastfeeding Centre between 1991-1994 was conducted to identify and classify possible causes of breast-feeding malnutrition among neonates who developed hypernatremic dehydration. RESULTS: Twenty-one cases hypernatremic dehydration were identified. Infant weight loss ranged from 8% to 30% of birth weight, and serum sodium levels ranged from 146 mmol/L to 207 mmol/L. In each case, maternal or infant factors (e.g., poor breast-feeding technique, lactation failure following postpartum hemorrhage and infant suckling disorders associated with cleft palate or ankyloglossia) that could interfere with either lactation or breast-feeding dynamics and account for insufficient breast milk intake were identified. INTERPRETATION: Prenatal and in-hospital screening for maternal and infant risk factors for breast-feeding malnutrition combined with early postpartum follow-up to detect excessive infant weight loss are important for the prevention of neonatal hypernatremic dehydration.  (+info)

Hyponatremia and hypernatremia in the elderly. (5/165)

Management of abnormalities in water homeostasis is frequently challenging. Because age-related changes and chronic diseases are often associated with impairment of water metabolism in elderly patients, it is absolutely essential for clinicians to be aware of the pathophysiology of hyponatremia and hypernatremia in the elderly. The sensation of thirst, renal function, concentrating abilities and hormonal modulators of salt and water balance are often impaired in the elderly, which makes such patients highly susceptible to morbid and iatrogenic events involving salt and water. Clinicians should use a systematic approach in evaluating water and sodium problems, utilizing a comprehensive history and physical examination, and a few directed laboratory tests to make the clinical diagnosis. Furthermore, clinicians should have a clear appreciation of the roles that iatrogenic interventions and lapses in nutrition and nursing care frequently play in upsetting the homeostatic balance in elderly patients, particularly those who are in longterm institutional and inpatient settings.  (+info)

Isosorbide in treatment of infantile hydrocephalus. (6/165)

This paper reports the experiences of the second clinical trial in the use of isosorbide in the treatment of 34 selected cases of infantile hydrocephalus of all types. Subject to careful biochemical monitoring of serum electrolyte, urea, and acid-base balance, treatment with 2 g/kg body weight 6-hourly is safe. Side effects are immediately eliminated by interrupting therapy. With lower dosage, prolonged maintenance therapy was possible, for as long as 11 months, without side effects and with need for much less frequent biochemical monitoring. Isosorbide effectively prevented the need for shunt therapy in 10 of 34 patients, including 3 infants with uncomplicated congenital hydrocephalus of moderate degree and infants whose hydrocephalus was associated with spina bifida and whose cerebral mantle was between 20 to 25 mm. In posthaemorrhagic and postmeningitic hydrocephalus valuable time was gained before shunt therapy until the infant and his CSF were fit for operation.  (+info)

Successful treatment in the patient with serum sodium level greater than 200 mEq/L. (7/165)

Hypernatremia developing in nonhospitalized adults is predominantly a disease of the elderly and mentally handicapped patients, possibly revealing inadequate nursing care of these patients. It has long been claimed that the duration of hypernatremia and its rate of correction are correlated with improvement in patients' neurologic status. Since there are only a handful of cases with serum sodium levels greater than 200 mEq/L until recently, it is not clear at what rate plasma sodium concentration can be safely normalized in severe hypernatremic patients. We report a case of severe hypernatremia with survival. This patient underwent rapid correction of serum sodium concentration during the management of this metabolic derangement using isotonic solution.  (+info)

Hypokalaemia and paralysis. (8/165)

It is not uncommon for patients to present to the emergency room with severe weakness and a markedly low plasma potassium concentration. We attempted to identify useful clues to the diagnosis of hypokalaemic periodic paralysis (HPP), because its acute treatment aims are unique. We retrospectively reviewed charts over a 10-year period: HPP was the initial diagnosis in 97 patients. Mean patient age was 29+/-1.1 and the male:female ratio was 77:20. When the final diagnosis was HPP (n=73), the acid-base state was normal, the urine K(+) concentration was low, and the transtubular K(+) concentration gradient (TTKG) was <3. In patients with thyrotoxic periodic paralysis (TPP) (n=39), hypokalaemia was very commonly accompanied by hypophosphataemia (1.9+/-0.1 mg/dl). A clinical diagnosis of sporadic periodic paralysis (SPP) was made if hyperthyroidism and a family history of HPP were both absent (n=29). One subgroup of patients with HPP had a severe degree of hypernatraemia (167+/-5.0 mmol/l, n=3). There were only two patients with familial periodic paralysis (FPP). In 24 patients, the initial diagnosis was HPP, but subsequent studies failed to confirm this diagnosis. Each of these patients had an acid-base disorder, a high rate of renal K(+) excretion in the presence of hypokalaemia, and a TTKG of close to 7. With respect to therapy, much less K(+) was given to patients with HPP, yet 1:3 subsequently had a plasma K(+) concentration that eventually exceeded 5.0 mmol/l. Using plasma acid-base status, phosphate and K(+) excretion parameters allows a presumptive diagnosis of HPP with more confidence in the emergency room.  (+info)

Hypernatremia is a medical condition characterized by an abnormally high concentration of sodium (na+) in the blood, specifically a serum sodium level greater than 145 mEq/L. Sodium is an essential electrolyte that helps regulate water balance in and around your cells. It's crucial for many body functions, including the maintenance of blood pressure, regulation of nerve and muscle function, and regulation of fluid balance.

Hypernatremia typically results from a deficit of total body water relative to solute, which can be caused by decreased water intake, increased water loss, or a combination of both. Common causes include dehydration due to severe vomiting or diarrhea, excessive sweating, burns, kidney diseases, and the use of certain medications such as diuretics.

Symptoms of hypernatremia can range from mild to severe and may include thirst, muscle weakness, lethargy, irritability, confusion, seizures, and in extreme cases, coma or even death. Treatment typically involves correcting the underlying cause and gradually rehydrating the individual with intravenous fluids to restore normal sodium levels.

Hypothalamic neoplasms refer to tumors that originate in the hypothalamus, a small region of the brain that is located at the base of the brain and forms part of the limbic system. The hypothalamus plays a critical role in regulating many bodily functions, including hormone release, temperature regulation, hunger, thirst, sleep, and emotional behavior.

Hypothalamic neoplasms can be benign or malignant and can arise from various cell types within the hypothalamus, such as neurons, glial cells, or supportive tissue. These tumors can cause a variety of symptoms depending on their size, location, and rate of growth. Common symptoms include endocrine disorders (such as diabetes insipidus or precocious puberty), visual disturbances, headaches, behavioral changes, and cognitive impairment.

The diagnosis of hypothalamic neoplasms typically involves a combination of clinical evaluation, imaging studies (such as MRI or CT scans), and sometimes biopsy or surgical removal of the tumor. Treatment options depend on the type, size, and location of the tumor but may include surgery, radiation therapy, chemotherapy, or a combination of these approaches. Regular follow-up care is essential to monitor for recurrence or progression of the tumor.

Thirst, also known as dry mouth or polydipsia, is a physiological need or desire to drink fluids to maintain fluid balance and hydration in the body. It is primarily regulated by the hypothalamus in response to changes in osmolality and volume of bodily fluids, particularly blood. Thirst can be triggered by various factors such as dehydration, excessive sweating, diarrhea, vomiting, fever, burns, certain medications, and medical conditions affecting the kidneys, adrenal glands, or other organs. It is a vital homeostatic mechanism to ensure adequate hydration and proper functioning of various bodily systems.

Dehydration is a condition that occurs when your body loses more fluids than it takes in. It's normal to lose water throughout the day through activities like breathing, sweating, and urinating; however, if you don't replenish this lost fluid, your body can become dehydrated.

Mild to moderate dehydration can cause symptoms such as:
- Dry mouth
- Fatigue or weakness
- Dizziness or lightheadedness
- Headache
- Dark colored urine
- Muscle cramps

Severe dehydration can lead to more serious health problems, including heat injury, urinary and kidney problems, seizures, and even hypovolemic shock, a life-threatening condition that occurs when your blood volume is too low.

Dehydration can be caused by various factors such as illness (e.g., diarrhea, vomiting), excessive sweating, high fever, burns, alcohol consumption, and certain medications. It's essential to stay hydrated by drinking plenty of fluids, especially during hot weather, exercise, or when you're ill.

Hyponatremia is a condition characterized by abnormally low sodium levels in the blood, specifically levels less than 135 mEq/L. Sodium is an essential electrolyte that helps regulate water balance in and around your cells and plays a crucial role in nerve and muscle function. Hyponatremia can occur due to various reasons, including certain medical conditions, medications, or excessive water intake leading to dilution of sodium in the body. Symptoms may range from mild, such as nausea, confusion, and headache, to severe, like seizures, coma, or even death in extreme cases. It's essential to seek medical attention if you suspect hyponatremia, as prompt diagnosis and treatment are vital for a favorable outcome.

Water-electrolyte imbalance refers to a disturbance in the balance of water and electrolytes (such as sodium, potassium, chloride, and bicarbonate) in the body. This imbalance can occur when there is an excess or deficiency of water or electrolytes in the body, leading to altered concentrations in the blood and other bodily fluids.

Such imbalances can result from various medical conditions, including kidney disease, heart failure, liver cirrhosis, severe dehydration, burns, excessive sweating, vomiting, diarrhea, and certain medications. Symptoms of water-electrolyte imbalance may include weakness, fatigue, muscle cramps, seizures, confusion, and in severe cases, coma or even death. Treatment typically involves addressing the underlying cause and correcting the electrolyte and fluid levels through appropriate medical interventions.

A hypertonic saline solution is a type of medical fluid that contains a higher concentration of salt (sodium chloride) than is found in the average person's blood. This solution is used to treat various medical conditions, such as dehydration, brain swelling, and increased intracranial pressure.

The osmolarity of a hypertonic saline solution typically ranges from 1500 to 23,400 mOsm/L, with the most commonly used solutions having an osmolarity of around 3000 mOsm/L. The high sodium concentration in these solutions creates an osmotic gradient that draws water out of cells and into the bloodstream, helping to reduce swelling and increase fluid volume in the body.

It is important to note that hypertonic saline solutions should be administered with caution, as they can cause serious side effects such as electrolyte imbalances, heart rhythm abnormalities, and kidney damage if not used properly. Healthcare professionals must carefully monitor patients receiving these solutions to ensure safe and effective treatment.

Fluid therapy, in a medical context, refers to the administration of fluids into a patient's circulatory system for various therapeutic purposes. This can be done intravenously (through a vein), intraosseously (through a bone), or subcutaneously (under the skin). The goal of fluid therapy is to correct or prevent imbalances in the body's fluids and electrolytes, maintain or restore blood volume, and support organ function.

The types of fluids used in fluid therapy can include crystalloids (which contain electrolytes and water) and colloids (which contain larger molecules like proteins). The choice of fluid depends on the patient's specific needs and condition. Fluid therapy is commonly used in the treatment of dehydration, shock, sepsis, trauma, surgery, and other medical conditions that can affect the body's fluid balance.

Proper administration of fluid therapy requires careful monitoring of the patient's vital signs, urine output, electrolyte levels, and overall clinical status to ensure that the therapy is effective and safe.

Diabetes Insipidus is a medical condition characterized by the excretion of large amounts of dilute urine (polyuria) and increased thirst (polydipsia). It is caused by a deficiency in the hormone vasopressin (also known as antidiuretic hormone or ADH), which regulates the body's water balance.

In normal physiology, vasopressin is released from the posterior pituitary gland in response to an increase in osmolality of the blood or a decrease in blood volume. This causes the kidneys to retain water and concentrate the urine. In Diabetes Insipidus, there is either a lack of vasopressin production (central diabetes insipidus) or a decreased response to vasopressin by the kidneys (nephrogenic diabetes insipidus).

Central Diabetes Insipidus can be caused by damage to the hypothalamus or pituitary gland, such as from tumors, trauma, or surgery. Nephrogenic Diabetes Insipidus can be caused by genetic factors, kidney disease, or certain medications that interfere with the action of vasopressin on the kidneys.

Treatment for Diabetes Insipidus depends on the underlying cause. In central diabetes insipidus, desmopressin, a synthetic analogue of vasopressin, can be administered to replace the missing hormone. In nephrogenic diabetes insipidus, treatment may involve addressing the underlying kidney disease or adjusting medications that interfere with vasopressin action. It is important for individuals with Diabetes Insipidus to maintain adequate hydration and monitor their fluid intake and urine output.

Hyperglycemic Hyperosmolar Nonketotic Coma (HHNC) is a serious complication of diabetes, specifically type 2, that occurs when blood glucose levels rise to extremely high levels, typically above 600 mg/dL. This condition is often accompanied by severe dehydration due to excessive urination and an inability to consume adequate fluids.

The term "hyperosmolar" refers to the high concentration of glucose in the blood, which increases the osmolality (or osmotic pressure) of the blood. This can lead to water moving out of cells and into the bloodstream to try to balance out the concentration, causing severe dehydration.

The term "nonketotic" means that there is no significant production of ketone bodies, which are produced when the body breaks down fat for energy in the absence of sufficient insulin. This differentiates HHNC from diabetic ketoacidosis (DKA), another serious complication of diabetes.

The "coma" part of the term refers to the fact that HHNC can cause altered mental status, ranging from confusion and disorientation to coma, due to the effects of dehydration and high blood glucose levels on the brain.

HHNC is a medical emergency that requires immediate treatment in a hospital setting. Treatment typically involves administering fluids to rehydrate the body, insulin to lower blood glucose levels, and addressing any other underlying conditions or complications. If left untreated, HHNC can be life-threatening.

Water-electrolyte balance refers to the regulation of water and electrolytes (sodium, potassium, chloride, bicarbonate) in the body to maintain homeostasis. This is crucial for various bodily functions such as nerve impulse transmission, muscle contraction, fluid balance, and pH regulation. The body maintains this balance through mechanisms that control water intake, excretion, and electrolyte concentration in various body fluids like blood and extracellular fluid. Disruptions in water-electrolyte balance can lead to dehydration or overhydration, and imbalances in electrolytes can cause conditions such as hyponatremia (low sodium levels) or hyperkalemia (high potassium levels).

Neurogenic diabetes insipidus is a condition characterized by the production of large amounts of dilute urine (polyuria) and increased thirst (polydipsia) due to deficiency of antidiuretic hormone (ADH), also known as vasopressin, which is produced by the hypothalamus and stored in the posterior pituitary gland.

Neurogenic diabetes insipidus can occur when there is damage to the hypothalamus or pituitary gland, leading to a decrease in ADH production or release. Causes of neurogenic diabetes insipidus include brain tumors, head trauma, surgery, meningitis, encephalitis, and autoimmune disorders.

In this condition, the kidneys are unable to reabsorb water from the urine due to the lack of ADH, resulting in the production of large volumes of dilute urine. This can lead to dehydration, electrolyte imbalances, and other complications if not properly managed. Treatment typically involves replacing the missing ADH with a synthetic hormone called desmopressin, which can be administered as a nasal spray, oral tablet, or injection.

Desmopressin, also known as 1-deamino-8-D-arginine vasopressin (dDAVP), is a synthetic analogue of the natural hormone arginine vasopressin. It is commonly used in medical practice for the treatment of diabetes insipidus, a condition characterized by excessive thirst and urination due to lack of antidiuretic hormone (ADH).

Desmopressin works by binding to V2 receptors in the kidney, which leads to increased water reabsorption and reduced urine production. It also has some effect on V1 receptors, leading to vasoconstriction and increased blood pressure. However, its primary use is for its antidiuretic effects.

In addition to its use in diabetes insipidus, desmopressin may also be used to treat bleeding disorders such as hemophilia and von Willebrand disease, as it can help to promote platelet aggregation and reduce bleeding times. It is available in various forms, including nasal sprays, injectable solutions, and oral tablets or dissolvable films.

Osmolar concentration is a measure of the total number of solute particles (such as ions or molecules) dissolved in a solution per liter of solvent (usually water), which affects the osmotic pressure. It is expressed in units of osmoles per liter (osmol/L). Osmolarity and osmolality are related concepts, with osmolarity referring to the number of osmoles per unit volume of solution, typically measured in liters, while osmolality refers to the number of osmoles per kilogram of solvent. In clinical contexts, osmolar concentration is often used to describe the solute concentration of bodily fluids such as blood or urine.

Sodium is an essential mineral and electrolyte that is necessary for human health. In a medical context, sodium is often discussed in terms of its concentration in the blood, as measured by serum sodium levels. The normal range for serum sodium is typically between 135 and 145 milliequivalents per liter (mEq/L).

Sodium plays a number of important roles in the body, including:

* Regulating fluid balance: Sodium helps to regulate the amount of water in and around your cells, which is important for maintaining normal blood pressure and preventing dehydration.
* Facilitating nerve impulse transmission: Sodium is involved in the generation and transmission of electrical signals in the nervous system, which is necessary for proper muscle function and coordination.
* Assisting with muscle contraction: Sodium helps to regulate muscle contractions by interacting with other minerals such as calcium and potassium.

Low sodium levels (hyponatremia) can cause symptoms such as confusion, seizures, and coma, while high sodium levels (hypernatremia) can lead to symptoms such as weakness, muscle cramps, and seizures. Both conditions require medical treatment to correct.

The term "drinking" is commonly used to refer to the consumption of beverages, but in a medical context, it usually refers to the consumption of alcoholic drinks. According to the Merriam-Webster Medical Dictionary, "drinking" is defined as:

1. The act or habit of swallowing liquid (such as water, juice, or alcohol)
2. The ingestion of alcoholic beverages

It's important to note that while moderate drinking may not pose significant health risks for some individuals, excessive or binge drinking can lead to a range of negative health consequences, including addiction, liver disease, heart disease, and increased risk of injury or violence.

Diabetes insipidus can strike in one of four different forms. There are two types of this disorder, however, that are more common than others. Central diabetes insipidus is caused by a reduction of the anti-diuretic hormone vasopression, causing the kidneys to continue pulling water out of the body because it is registering an excessive amount. This form is usually caused by an injury or tumor that involves the hypothalamus or the pituitary gland, but surgeries in that area may also cause this disorder.. The other common form of diabetes insipidus is called nephrogenic. This refers to the fact that the kidneys are failing to recognize the hormones that are present in the body. There is enough vasopressin being produced, but the kidneys dont respond to the hormones at all. The end result is that excessive urination is created and excessive thirst occurs as a result. This may be caused by an injury or may be genetic in nature.. The two uncommon types of diabetes insipidus are gestational and ...

The most common reason for decreased urine osmolality is an excessive level of fluids being consumed. This may also be achieved with high levels of caffeine intake throughout the day. When fluids are being regularly consumed or forced out of the body because of the action of a diuretic, this can dramatically lower urine osmolality without their being a health issue involved.. Diabetes insipidus urine osmolality is also typically much lower that the normal averages that are reported in this guide. Generally anything under 300 mOsm/kg of water is going to point toward this health condition, but results in the 200 mOsm/kg range is considered a hallmark for diabetes insipidus diagnosis.. Nephrogenic diabetes insipidus will typically have urine osmolality results that are less than 200 mOsm/kg of water even if the clinical signs are pointing toward hypovolemia, which is a decreased blood volume. Central diabetes insipidus will see similar results with water deprivation testing, but will correct ...
