A condition caused by prolonged exposure to excessive HUMAN GROWTH HORMONE in adults. It is characterized by bony enlargement of the FACE; lower jaw (PROGNATHISM); hands; FEET; HEAD; and THORAX. The most common etiology is a GROWTH HORMONE-SECRETING PITUITARY ADENOMA. (From Joynt, Clinical Neurology, 1992, Ch36, pp79-80)
A 191-amino acid polypeptide hormone secreted by the human adenohypophysis (PITUITARY GLAND, ANTERIOR), also known as GH or somatotropin. Synthetic growth hormone, termed somatropin, has replaced the natural form in therapeutic usage such as treatment of dwarfism in children with growth hormone deficiency.
A pituitary tumor that secretes GROWTH HORMONE. In humans, excess HUMAN GROWTH HORMONE leads to ACROMEGALY.
Neoplasms which arise from or metastasize to the PITUITARY GLAND. The majority of pituitary neoplasms are adenomas, which are divided into non-secreting and secreting forms. Hormone producing forms are further classified by the type of hormone they secrete. Pituitary adenomas may also be characterized by their staining properties (see ADENOMA, BASOPHIL; ADENOMA, ACIDOPHIL; and ADENOMA, CHROMOPHOBE). Pituitary tumors may compress adjacent structures, including the HYPOTHALAMUS, several CRANIAL NERVES, and the OPTIC CHIASM. Chiasmal compression may result in bitemporal HEMIANOPSIA.
A potent, long-acting synthetic SOMATOSTATIN octapeptide analog that inhibits secretion of GROWTH HORMONE and is used to treat hormone-secreting tumors; DIABETES MELLITUS; HYPOTENSION, ORTHOSTATIC; HYPERINSULINISM; hypergastrinemia; and small bowel fistula.
A 14-amino acid peptide named for its ability to inhibit pituitary GROWTH HORMONE release, also called somatotropin release-inhibiting factor. It is expressed in the central and peripheral nervous systems, the gut, and other organs. SRIF can also inhibit the release of THYROID-STIMULATING HORMONE; PROLACTIN; INSULIN; and GLUCAGON besides acting as a neurotransmitter and neuromodulator. In a number of species including humans, there is an additional form of somatostatin, SRIF-28 with a 14-amino acid extension at the N-terminal.
The condition of accelerated and excessive GROWTH in children or adolescents who are exposed to excess HUMAN GROWTH HORMONE before the closure of EPIPHYSES. It is usually caused by somatotroph hyperplasia or a GROWTH HORMONE-SECRETING PITUITARY ADENOMA. These patients are of abnormally tall stature, more than 3 standard deviations above normal mean height for age.
A well-characterized basic peptide believed to be secreted by the liver and to circulate in the blood. It has growth-regulating, insulin-like, and mitogenic activities. This growth factor has a major, but not absolute, dependence on GROWTH HORMONE. It is believed to be mainly active in adults in contrast to INSULIN-LIKE GROWTH FACTOR II, which is a major fetal growth factor.
A polypeptide that is secreted by the adenohypophysis (PITUITARY GLAND, ANTERIOR). Growth hormone, also known as somatotropin, stimulates mitosis, cell differentiation and cell growth. Species-specific growth hormones have been synthesized.
A benign epithelial tumor with a glandular organization.
A semisynthetic ergotamine alkaloid that is a dopamine D2 agonist. It suppresses prolactin secretion.
A benign tumor, usually found in the anterior lobe of the pituitary gland, whose cells stain with acid dyes. Such pituitary tumors may give rise to excessive secretion of growth hormone, resulting in gigantism or acromegaly. A specific type of acidophil adenoma may give rise to nonpuerperal galactorrhea. (Dorland, 27th ed)
A peptide of 44 amino acids in most species that stimulates the release and synthesis of GROWTH HORMONE. GHRF (or GRF) is synthesized by neurons in the ARCUATE NUCLEUS of the HYPOTHALAMUS. After being released into the pituitary portal circulation, GHRF stimulates GH release by the SOMATOTROPHS in the PITUITARY GLAND.
A tripeptide that stimulates the release of THYROTROPIN and PROLACTIN. It is synthesized by the neurons in the PARAVENTRICULAR NUCLEUS of the HYPOTHALAMUS. After being released into the pituitary portal circulation, TRH (was called TRF) stimulates the release of TSH and PRL from the ANTERIOR PITUITARY GLAND.
Cell surface proteins that bind GROWTH HORMONE with high affinity and trigger intracellular changes influencing the behavior of cells. Activation of growth hormone receptors regulates amino acid transport through cell membranes, RNA translation to protein, DNA transcription, and protein and amino acid catabolism in many cell types. Many of these effects are mediated indirectly through stimulation of the release of somatomedins.
A series of structurally-related alkaloids that contain the ergoline backbone structure.
Peptides whose amino and carboxy ends are linked together with a peptide bond forming a circular chain. Some of them are ANTI-INFECTIVE AGENTS. Some of them are biosynthesized non-ribosomally (PEPTIDE BIOSYNTHESIS, NON-RIBOSOMAL).
A benign tumor of the anterior pituitary in which the cells do not stain with acidic or basic dyes.
A pituitary adenoma which secretes PROLACTIN, leading to HYPERPROLACTINEMIA. Clinical manifestations include AMENORRHEA; GALACTORRHEA; IMPOTENCE; HEADACHE; visual disturbances; and CEREBROSPINAL FLUID RHINORRHEA.
Increased levels of PROLACTIN in the BLOOD, which may be associated with AMENORRHEA and GALACTORRHEA. Relatively common etiologies include PROLACTINOMA, medication effect, KIDNEY FAILURE, granulomatous diseases of the PITUITARY GLAND, and disorders which interfere with the hypothalamic inhibition of prolactin release. Ectopic (non-pituitary) production of prolactin may also occur. (From Joynt, Clinical Neurology, 1992, Ch36, pp77-8)
A small, unpaired gland situated in the SELLA TURCICA. It is connected to the HYPOTHALAMUS by a short stalk which is called the INFUNDIBULUM.
The presence of an excessively large tongue, which may be congenital or may develop as a result of a tumor or edema due to obstruction of lymphatic vessels, or it may occur in association with hyperpituitarism or acromegaly. It also may be associated with malocclusion because of pressure of the tongue on the teeth. (From Jablonski, Dictionary of Dentistry, 1992)
An irregular unpaired bone situated at the SKULL BASE and wedged between the frontal, temporal, and occipital bones (FRONTAL BONE; TEMPORAL BONE; OCCIPITAL BONE). Sphenoid bone consists of a median body and three pairs of processes resembling a bat with spread wings. The body is hollowed out in its inferior to form two large cavities (SPHENOID SINUS).
Chemical substances having a specific regulatory effect on the activity of a certain organ or organs. The term was originally applied to substances secreted by various ENDOCRINE GLANDS and transported in the bloodstream to the target organs. It is sometimes extended to include those substances that are not produced by the endocrine glands but that have similar effects.
A regressive change of teeth characterized by excessive development of secondary cementum on the tooth surface. It may occur on any part of the root, but the apical two-thirds are most commonly affected. (Dorland, 27th ed)
FIBROUS DYSPLASIA OF BONE affecting several bones. When melanotic pigmentation (CAFE-AU-LAIT SPOTS) and multiple endocrine hyperfunction are additionally associated it is referred to as Albright syndrome.
A test to determine the ability of an individual to maintain HOMEOSTASIS of BLOOD GLUCOSE. It includes measuring blood glucose levels in a fasting state, and at prescribed intervals before and after oral glucose intake (75 or 100 g) or intravenous infusion (0.5 g/kg).
Chemical substances which inhibit the function of the endocrine glands, the biosynthesis of their secreted hormones, or the action of hormones upon their specific sites.
Surgical removal or destruction of the hypophysis, or pituitary gland. (Dorland, 28th ed)
Surgery performed on any endocrine gland.

Neurosurgery restores late GH rise after glucose-induced suppression in cured acromegalics. (1/672)

OBJECTIVE AND DESIGN: A decrease of GH levels below 2 microg/l after an oral glucose tolerance test (OGTT) is still currently accepted as the gold standard for assessing cure in surgically treated acromegaly. Whether glucose-induced suppression of GH is accompanied by a restoration of normal GH late rebound has not yet been evaluated in this disease. In order to assess the restoration of normal GH regulation after removal of a pituitary adenoma, we have evaluated GH changes after an OGTT in a series of selected acromegalic patients (transsphenoidal surgery and lack of pituitary failure). METHODS: Twenty-nine patients (13 male, 16 female, age range 27-70 years) entered the study. Their neuroradiological imaging before neurosurgery showed microadenoma in 7, intrasellar macroadenoma in 8 and macroadenoma with extrasellar extension in 14. Plasma GH levels were assayed up to 300 min after glucose administration (75 g p.o.) and IGF-I on basal samples. RESULTS: Basal GH levels were below 5 microg/l in 20 patients and below 2 microg/l in 5 of these. Normal age-adjusted IGF-I levels were observed in 12 patients. GH values were suppressed below 2 microg/l during an OGTT in 13 patients, and below 1 microg/l in 7 of these. In 9 patients out of these 13, a marked rise in GH levels occurred after nadir. Baseline and nadir GH values of these 9 patients were not different from the corresponding values of the other 4 patients without OGTT-induced late GH peaks. CONCLUSIONS: GH rebound after GH nadir occurs in acromegalic patients considered as cured on the basis of OGTT-induced GH suppression and/or IGF-I normalization. The restoration of this physiological response could be regarded as a marker of recovered/preserved integrity of the hypothalamic-pituitary axis. Even though the reason for this GH rebound has not yet been elucidated (GHRH discharge?/end of somatostatin inhibition?), the lack of late GH peak in the patients regarded as cured by the usual criteria could be due to injury to the pituitary stalk caused by the adenoma or by surgical manipulation.  (+info)

Kleine-Levin and Munchausen syndromes in a patient with recurrent acromegaly. (2/672)

Hypothalamic disease often affects the patients' personality and this also applies to pituitary tumors with suprasellar extension. We report on a patient with a 12-year history of recurrent acromegaly, treated with three transphenoidal operations, single field radiation therapy and bromocriptine/octreotide administration. During the course of follow-up she presented with self-inflicted anemia and Kleine-Levin syndrome (hypersomnia, hyperphagia and hypersexuality). Furthermore, she developed post-radiation necrosis within the right temporal lobe. Whether her neurological and personality disorders result - at least partially - from the acromegaly or the temporal lobe necrosis remains unclear.  (+info)

Growth in Sotos syndrome. (3/672)

Although there are several reports on infant and childhood growth in patients with Sotos syndrome, there is little information on the final height achieved and puberty. Growth data on 40 patients (20 female and 20 male) aged 2-31 years were collected. These showed that patients with Sotos syndrome are excessively tall at birth, during infancy, and during childhood. Disproportionately long limbs constitute much of the increase in stature. However, the combination of advanced bone age and early onset of menarche led to a mean (SD) final height of 172.9 (5.7) cm in women. This is within the normal range for the population. Most of the men also attained a final height (mean, 184.3 cm; SD, 6.0) within the normal range, although exceptions were more likely in men than in women. Therefore, these results show that most patients with Sotos syndrome do not require intervention to limit their adult height.  (+info)

Cell death in acromegalic cardiomyopathy. (4/672)

BACKGROUND: Prolonged untreated acromegaly leads to a nonspecific myopathy characterized by ventricular dysfunction and failure. However, the mechanisms responsible for the alterations of cardiac pump function remain to be defined. Because cell death is implicated in most cardiac disease processes, the possibility has been raised that myocyte apoptosis may occur in the acromegalic heart, contributing to the deterioration of ventricular hemodynamics. METHODS AND RESULTS: Ten acromegalic patients with diastolic dysfunction and 4 also with systolic dysfunction were subjected to electrocardiography, Holter monitoring, 2-dimensional echocardiography, cardiac catheterization, and biventricular and coronary angiography before surgical removal of a growth hormone-secreting pituitary adenoma. Endomyocardial biopsies were obtained and analyzed quantitatively in terms of tissue scarring and myocyte and nonmyocyte apoptosis. Myocardial samples from papillary muscles of patients who underwent valve replacement for mitral stenosis were used for comparison. The presence of apoptosis in myocytes and interstitial cells was determined by confocal microscopy with the use of 2 histochemical methods, consisting of terminal deoxynucleotidyl transferase (TdT) assay and Taq probe in situ ligation. Acromegaly was characterized by a 495-fold and 305-fold increase in apoptosis of myocytes and nonmyocytes, respectively. The magnitude of myocyte apoptosis correlated with the extent of impairment in ejection fraction and the duration of the disease. A similar correlation was found with the magnitude of collagen accumulation, indicative of previous myocyte necrosis. Myocyte death was independent from the hormonal levels of growth hormone and insulin-like growth factor-1. Apoptosis of interstitial cells did not correlate with ejection fraction. CONCLUSIONS: Myocyte cell death, apoptotic and necrotic in nature, may be critical for the development of ventricular dysfunction and its progression to cardiac failure with acromegaly.  (+info)

Prolonged large bowel transit increases serum deoxycholic acid: a risk factor for octreotide induced gallstones. (5/672)

BACKGROUND: Treatment of acromegaly with octreotide increases the proportion of deoxycholic acid in, and the cholesterol saturation of, bile and induces the formation of gallstones. Prolongation of intestinal transit has been proposed as the mechanism for the increase in the proportion of deoxycholic acid in bile. AIMS: To study the effects of octreotide on intestinal transit in acromegalic patients during octreotide treatment, and to examine the relation between intestinal transit and bile acid composition in fasting serum. METHODS: Mouth to caecum and large bowel transit times, and the proportion of deoxycholic acid in fasting serum were measured in non-acromegalic controls, acromegalic patients untreated with octreotide, acromegalics on long term octreotide, and patients with simple constipation. Intestinal transit and the proportion of deoxycholic acid were compared in acromegalic patients before and during octreotide. RESULTS: Acromegalics untreated with octreotide had longer mouth to caecum and large bowel transit times than controls. Intestinal transit was further prolonged by chronic octreotide treatment. There were significant linear relations between large bowel transit time and the proportion of deoxycholic acid in the total, conjugated, and unconjugated fractions of fasting serum. CONCLUSIONS: These data support the hypothesis that, by prolonging large bowel transit, octreotide increases the proportion of deoxycholic acid in fasting serum (and, by implication, in bile) and thereby the risk of gallstone formation.  (+info)

Pituitary tumours in the elderly: a 20 year experience. (6/672)

The proportion of the elderly in the population is increasing, and the appreciation and management of medical problems in this age group will therefore become more important. We therefore decided to determine the clinical features and types of pituitary tumour presenting in the elderly, and to examine the treatment and outcome in this group. We conducted a retrospective case-note review from a specialist endocrine and neurosurgical unit in a tertiary referral centre. Eighty-four patients aged 65 years and over on diagnosis of a pituitary tumour were referred to the unit between 1975 and 1996. There were 45 males and 39 females, and the mean age was 72.4 years (range 65-86). Over half of the pituitary lesions were non-functioning adenomas (NFAs) (60.7%). GH-secreting tumours were present in 11 (13.1%) and macroprolactinomas in 7 (8.1%). Four patients had microadenomas and 17 had miscellaneous pituitary-related lesions. Visual deterioration was the commonest mode of presentation in 33 (39.3%), but 54 (64.3%) had evidence of visual impairment on detailed examination. Despite the majority of patients (80.8%) having coexisting medical conditions, trans-sphenoidal surgery was performed in 60 (71.4%) and was well tolerated with a zero peri- and post-operative mortality rate, and post-operative complications in 11 (13.1%). Pituitary tumours in the elderly are most frequently NFAs that present with visual deterioration and hypopituitarism. The fact that 46.5% were pan-hypopituitary on diagnosis and that 64.3% of patients had visual impairment suggests a delay in diagnosis in this age group. Despite significant coexisting medical pathology in this large series of patients, surgery was safe and successful in the majority.  (+info)

Octreotide suppresses the incretin glucagon-like peptide (7-36) amide in patients with acromegaly or clinically nonfunctioning pituitary tumors and in healthy subjects. (7/672)

OBJECTIVE: To study the effect of octreotide on glucagon-like peptide (7-36) amide (GLP-1) and insulin secretion in patients with pituitary tumors during preoperative treatment and in healthy subjects. DESIGN: Open design prospective clinical study. METHODS: Eighteen patients with pituitary macroadenomas (13 clinically nonfunctioning (NFA; 11/13 had GH insufficiency), 5 GH secreting (GHA)) received preoperative octreotide treatment: 3x100 microg/day s. c. for 3 months, and 3x500 microg/day s.c. for an additional 3 months. Seven healthy subjects received (for ethical reasons) only 3x100 microg/day for 10 days. A standardized meal (St-M) test, oral glucose test (oGTT) and i.v. glucose test (ivGTT) were done before octreotide therapy, on days 1, 2 and 3 (D1,2,3), after 3 months (M3) and 6 months (M6) of octreotide treatment in the patients, and before treatment, on D1,2,3 and on D8,9,10 of octreotide treatment in the healthy subjects. Serum GLP-1, insulin and GH as well as plasma glucose were determined for 180 min (oGTT, St-M) or 120 min (ivGTT). RESULTS: Pretreatment fasting GLP-1 concentrations as well as integrated responses (area under the curve 0-180 min) to oGTT and St-M were not significantly different between NFA, GHA and healthy subjects. During the oGTT, octreotide initially almost abolished the early (0-60 min) and diminished the late (60-180 min) GLP-1 and insulin responses in patients and healthy subjects. At M6 integrated insulin responses had significantly recovered, while the increase in GLP-1 response failed to reach significance (GLP-1: 56.5% of pretreatment at D2 versus 93.5% at M6 and 41.2 versus 63.1% in NFA and GHA respectively; insulin: 50.2 versus 71.2% and 35.5 versus 70. 4%). An escape of GLP-1 and insulin in healthy subjects (D2 versus D9) was not significant. Intestinal glucose absorption was apparently not reduced, since the early glucose rise was similar before and during octreotide treatment. During the St-M the GLP-1 and insulin responses were similarly suppressed by octreotide and recovered during ongoing treatment (GLP-1: 49.6% of pretreatment at D1 versus 79.0% at M6 in NFA and 46.9 versus 52.9% in GHA. Insulin: 27.6 versus 83.9% and 23.5 versus 54.4%). The escape was significant in NFA but not in GHA. In the healthy subjects the escape was already significant on D8 (GLP-1: 39.5% of pretreatment at D1 versus 68.3% at D8; insulin: 36.6 versus 53.8%). During the ivGTT GLP-1 did not increase. The early insulin response (0-30 min) was abolished by octreotide, followed by a reduced peak at 60 min. The reduction of the integrated insulin response during ivGTT was similar to that during oGTT. An insulin escape reached significance only for NFA (52. 6% of pretreatment at D3 versus 66.7% at M6). Glucose tolerance (KG value) deteriorated and did not improve during ongoing treatment. Octreotide suppressed the median GH concentration (8h profile) of the GHA patients from 10.3 microg/l (pretreatment) to 5.8, 6.3 and 3. 7 microg/l at D4, M3 and M6 with no escape. GH was 1.5 microg/l postoperatively. CONCLUSIONS: Octreotide abolishes the early and diminishes the late GLP-1 and insulin responses to oGTT and St-M in NFA and GHA patients and in healthy subjects. In contrast to GH, both hormones partially escape from suppression during ongoing therapy. During treatment with our conventional octreotide doses suppression of insulin secretion is maximal. Under these conditions an effect of the additional loss of GLP-1 is not apparent. Basal GLP-1 concentrations and integrated responses to oGTT and St-M were similar in healthy subjects and in patients with GH excess or GH insufficiency.  (+info)

A case of acromegaly accompanied by adrenal preclinical Cushing's syndrome. (8/672)

We encountered a 58-year-old woman with acromegaly accompanied by a cortisol-secreting adrenal tumor without clinical features of hypercortisolism. The simultaneous occurrence of these two endocrinopathies in one individual is extremely rare. She was diagnosed as having diabetes mellitus 8 years ago. Afterwards, in spite of insulin therapy, her hyperglycemia could not be well controlled. Her acromegaly and preclinical Cushing's syndrome were histopathologically proven to be due to a pituitary adenoma and an adrenocortical adenoma, respectively. Successful treatment for these endocrinopathies resulted in greatly improved blood sugar control because of a reduction in insulin resistance. In this case of preclinical Cushing's syndrome, replacement therapy with glucocorticoid was able to be discontinued at only 8 weeks after adrenalectomy, so that the period of necessary replacement was much shorter than that for overt Cushing's syndrome. This is the first report describing insulin resistance before and after treatment in a case of acromegaly accompanied by adrenal preclinical Cushing's syndrome.  (+info)

Acromegaly is a rare hormonal disorder that typically occurs in middle-aged adults. It results from the pituitary gland producing too much growth hormone (GH) during adulthood. The excessive production of GH leads to abnormal growth of body tissues, particularly in the hands, feet, and face.

The term "acromegaly" is derived from two Greek words: "akros," meaning extremities, and "megaly," meaning enlargement. In most cases, acromegaly is caused by a benign tumor (adenoma) of the pituitary gland, which results in overproduction of GH.

Common symptoms include enlarged hands and feet, coarse facial features, deepened voice, joint pain, and sweating. If left untreated, acromegaly can lead to serious complications such as diabetes, hypertension, heart disease, and arthritis. Treatment usually involves surgical removal of the tumor, radiation therapy, or medication to control GH production.

Human Growth Hormone (HGH), also known as somatotropin, is a peptide hormone produced in the pituitary gland. It plays a crucial role in human development and growth by stimulating the production of another hormone called insulin-like growth factor 1 (IGF-1). IGF-1 promotes the growth and reproduction of cells throughout the body, particularly in bones and other tissues. HGH also helps regulate body composition, body fluids, muscle and bone growth, sugar and fat metabolism, and possibly heart function. It is essential for human development and continues to have important effects throughout life. The secretion of HGH decreases with age, which is thought to contribute to the aging process.

A Growth Hormone-Secreting Pituitary Adenoma (GH-secreting pituitary adenoma, or GHoma) is a type of benign tumor that develops in the pituitary gland and results in excessive production of growth hormone (GH). This leads to a condition known as acromegaly if it occurs in adults, or gigantism if it occurs in children before the closure of the growth plates.

Symptoms of GH-secreting pituitary adenoma may include:

1. Coarsening of facial features
2. Enlargement of hands and feet
3. Deepened voice due to thickening of vocal cords
4. Increased sweating and body odor
5. Joint pain and stiffness
6. Sleep apnea
7. Fatigue, weakness, or muscle wasting
8. Headaches
9. Vision problems
10. Irregular menstrual periods in women
11. Erectile dysfunction in men

Diagnosis typically involves measuring the levels of GH and insulin-like growth factor 1 (IGF-1) in the blood, along with imaging tests like MRI or CT scans to locate and characterize the tumor. Treatment options include surgical removal of the tumor, radiation therapy, and medication to control GH production. Regular follow-ups are necessary to monitor for potential recurrence.

Pituitary neoplasms refer to abnormal growths or tumors in the pituitary gland, a small endocrine gland located at the base of the brain. These neoplasms can be benign (non-cancerous) or malignant (cancerous), with most being benign. They can vary in size and may cause various symptoms depending on their location, size, and hormonal activity.

Pituitary neoplasms can produce and secrete excess hormones, leading to a variety of endocrine disorders such as Cushing's disease (caused by excessive ACTH production), acromegaly (caused by excessive GH production), or prolactinoma (caused by excessive PRL production). They can also cause local compression symptoms due to their size, leading to headaches, vision problems, and cranial nerve palsies.

The exact causes of pituitary neoplasms are not fully understood, but genetic factors, radiation exposure, and certain inherited conditions may increase the risk of developing these tumors. Treatment options for pituitary neoplasms include surgical removal, radiation therapy, and medical management with drugs that can help control hormonal imbalances.

Octreotide is a synthetic analogue of the natural hormone somatostatin, which is used in medical treatment. It is a octapeptide with similar effects to somatostatin, but with a longer duration of action. Octreotide is primarily used in the management of acromegaly, gastroenteropancreatic neuroendocrine tumors (GEP-NETs), and diarrhea and flushing associated with carcinoid syndrome.

It works by inhibiting the release of several hormones, including growth hormone, insulin, glucagon, and gastrin. This results in a decrease in symptoms caused by excessive hormone secretion, such as reduced growth hormone levels in acromegaly, decreased tumor size in some GEP-NETs, and improved diarrhea and flushing in carcinoid syndrome.

Octreotide is available in several forms, including short-acting subcutaneous injections (Sandostatin®), long-acting depot intramuscular injections (Sandostatin LAR®), and a slow-release formulation for the treatment of diarrhea associated with AIDS (Mycapssa™).

The medical definition of Octreotide is:

A synthetic octapeptide analogue of somatostatin, used in the management of acromegaly, gastroenteropancreatic neuroendocrine tumors (GEP-NETs), and diarrhea and flushing associated with carcinoid syndrome. Octreotide inhibits the release of several hormones, including growth hormone, insulin, glucagon, and gastrin, leading to symptomatic improvement in these conditions. It is available as short-acting subcutaneous injections, long-acting depot intramuscular injections, and a slow-release formulation for diarrhea associated with AIDS.

Somatostatin is a hormone that inhibits the release of several hormones and also has a role in slowing down digestion. It is produced by the body in various parts of the body, including the hypothalamus (a part of the brain), the pancreas, and the gastrointestinal tract.

Somatostatin exists in two forms: somatostatin-14 and somatostatin-28, which differ in their length. Somatostatin-14 is the predominant form found in the brain, while somatostatin-28 is the major form found in the gastrointestinal tract.

Somatostatin has a wide range of effects on various physiological processes, including:

* Inhibiting the release of several hormones such as growth hormone, insulin, glucagon, and gastrin
* Slowing down digestion by inhibiting the release of digestive enzymes from the pancreas and reducing blood flow to the gastrointestinal tract
* Regulating neurotransmission in the brain

Somatostatin is used clinically as a diagnostic tool for detecting certain types of tumors that overproduce growth hormone or other hormones, and it is also used as a treatment for some conditions such as acromegaly (a condition characterized by excessive growth hormone production) and gastrointestinal disorders.

Gigantism is a rare medical condition characterized by excessive growth and height significantly above average. This occurs due to an overproduction of growth hormone (GH), also known as somatotropin, during the growth phase in childhood. The pituitary gland, a small gland located at the base of the brain, is responsible for producing this hormone.

In gigantism, the pituitary gland releases too much GH, leading to abnormal bone and tissue growth. This condition is different from acromegaly, which is characterized by excessive GH production in adulthood after the growth phase has ended. In both cases, the excess GH can lead to various health complications, including cardiovascular disease, diabetes, hypertension, and joint problems.

Gigantism is typically caused by a benign tumor called a pituitary adenoma that presses against and stimulates the production of GH from the anterior pituitary gland. Treatment usually involves surgical removal of the tumor or medication to control GH levels, depending on the severity and progression of the condition. Early diagnosis and treatment are crucial for managing the symptoms and preventing long-term health complications associated with gigantism.

Insulin-like growth factor I (IGF-I) is a hormone that plays a crucial role in growth and development. It is a small protein with structural and functional similarity to insulin, hence the name "insulin-like." IGF-I is primarily produced in the liver under the regulation of growth hormone (GH).

IGF-I binds to its specific receptor, the IGF-1 receptor, which is widely expressed throughout the body. This binding activates a signaling cascade that promotes cell proliferation, differentiation, and survival. In addition, IGF-I has anabolic effects on various tissues, including muscle, bone, and cartilage, contributing to their growth and maintenance.

IGF-I is essential for normal growth during childhood and adolescence, and it continues to play a role in maintaining tissue homeostasis throughout adulthood. Abnormal levels of IGF-I have been associated with various medical conditions, such as growth disorders, diabetes, and certain types of cancer.

Growth Hormone (GH), also known as somatotropin, is a peptide hormone secreted by the somatotroph cells in the anterior pituitary gland. It plays a crucial role in regulating growth, cell reproduction, and regeneration by stimulating the production of another hormone called insulin-like growth factor 1 (IGF-1) in the liver and other tissues. GH also has important metabolic functions, such as increasing glucose levels, enhancing protein synthesis, and reducing fat storage. Its secretion is regulated by two hypothalamic hormones: growth hormone-releasing hormone (GHRH), which stimulates its release, and somatostatin (SRIF), which inhibits its release. Abnormal levels of GH can lead to various medical conditions, such as dwarfism or gigantism if there are deficiencies or excesses, respectively.

An adenoma is a benign (noncancerous) tumor that develops from glandular epithelial cells. These types of cells are responsible for producing and releasing fluids, such as hormones or digestive enzymes, into the surrounding tissues. Adenomas can occur in various organs and glands throughout the body, including the thyroid, pituitary, adrenal, and digestive systems.

Depending on their location, adenomas may cause different symptoms or remain asymptomatic. Some common examples of adenomas include:

1. Colorectal adenoma (also known as a polyp): These growths occur in the lining of the colon or rectum and can develop into colorectal cancer if left untreated. Regular screenings, such as colonoscopies, are essential for early detection and removal of these polyps.
2. Thyroid adenoma: This type of adenoma affects the thyroid gland and may result in an overproduction or underproduction of hormones, leading to conditions like hyperthyroidism (overactive thyroid) or hypothyroidism (underactive thyroid).
3. Pituitary adenoma: These growths occur in the pituitary gland, which is located at the base of the brain and controls various hormonal functions. Depending on their size and location, pituitary adenomas can cause vision problems, headaches, or hormonal imbalances that affect growth, reproduction, and metabolism.
4. Liver adenoma: These rare benign tumors develop in the liver and may not cause any symptoms unless they become large enough to press on surrounding organs or structures. In some cases, liver adenomas can rupture and cause internal bleeding.
5. Adrenal adenoma: These growths occur in the adrenal glands, which are located above the kidneys and produce hormones that regulate stress responses, metabolism, and blood pressure. Most adrenal adenomas are nonfunctioning, meaning they do not secrete excess hormones. However, functioning adrenal adenomas can lead to conditions like Cushing's syndrome or Conn's syndrome, depending on the type of hormone being overproduced.

It is essential to monitor and manage benign tumors like adenomas to prevent potential complications, such as rupture, bleeding, or hormonal imbalances. Treatment options may include surveillance with imaging studies, medication to manage hormonal issues, or surgical removal of the tumor in certain cases.

Bromocriptine is a dopamine receptor agonist drug, which means it works by binding to and activating dopamine receptors in the brain. It has several therapeutic uses, including:

* Treatment of Parkinson's disease: Bromocriptine can be used alone or in combination with levodopa to help manage the symptoms of Parkinson's disease, such as stiffness, tremors, spasms, and poor muscle control.
* Suppression of lactation: Bromocriptine can be used to suppress milk production in women who are not breastfeeding or who have stopped breastfeeding but still have high levels of prolactin, a hormone that stimulates milk production.
* Treatment of pituitary tumors: Bromocriptine can be used to shrink certain types of pituitary tumors, such as prolactinomas, which are tumors that secrete excessive amounts of prolactin.
* Management of acromegaly: Bromocriptine can be used to manage the symptoms of acromegaly, a rare hormonal disorder characterized by abnormal growth and enlargement of body tissues, by reducing the production of growth hormone.

Bromocriptine is available in immediate-release and long-acting formulations, and it is usually taken orally. Common side effects of bromocriptine include nausea, dizziness, lightheadedness, and drowsiness. Serious side effects are rare but can include hallucinations, confusion, and priapism (prolonged erection).

An adenoma is a benign tumor that forms in glandular tissue. When referring to "acidophil," it describes the appearance of the cells under a microscope. Acidophils are cells that take up acidic dyes, giving them a distinct appearance. In the context of an adenoma, an acidophil adenoma would be a benign tumor composed of acidophil cells.

Acidophil adenomas are most commonly found in the pituitary gland and are also known as lactotroph or mammosomatotroph adenomas. These tumors can produce and release prolactin, growth hormone, or both, leading to various endocrine disorders such as hyperprolactinemia, acromegaly, or gigantism. Treatment options typically include surgical removal of the tumor or medical management with dopamine agonists or somatostatin analogs.

Growth Hormone-Releasing Hormone (GHRH) is a hormone that is produced and released by the hypothalamus, a small gland located in the brain. Its primary function is to stimulate the anterior pituitary gland to release growth hormone (GH) into the bloodstream. GH plays a crucial role in growth and development, particularly during childhood and adolescence, by promoting the growth of bones and muscles.

GHRH is a 44-amino acid peptide that binds to specific receptors on the surface of pituitary cells, triggering a series of intracellular signals that ultimately lead to the release of GH. The production and release of GHRH are regulated by various factors, including sleep, stress, exercise, and nutrition.

Abnormalities in the production or function of GHRH can lead to growth disorders, such as dwarfism or gigantism, as well as other hormonal imbalances. Therefore, understanding the role of GHRH in regulating GH release is essential for diagnosing and treating these conditions.

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.

Somatotropin receptors are a type of cell surface receptor that binds to and gets activated by the hormone somatotropin, also known as growth hormone (GH). These receptors are found in many tissues throughout the body, including the liver, muscle, and fat. When somatotropin binds to its receptor, it activates a series of intracellular signaling pathways that regulate various physiological processes such as growth, metabolism, and cell reproduction.

Somatotropin receptors belong to the class I cytokine receptor family and are composed of two subunits, a homodimer of extracellular glycoproteins that bind to the hormone and an intracellular tyrosine kinase domain that activates downstream signaling pathways. Mutations in the somatotropin receptor gene can lead to growth disorders such as dwarfism or gigantism, depending on whether the mutation results in a decrease or increase in receptor activity.

Ergolines are a group of ergot alkaloids that have been widely used in the development of various pharmaceutical drugs. These compounds are known for their ability to bind to and stimulate specific receptors in the brain, particularly dopamine receptors. As a result, they have been explored for their potential therapeutic benefits in the treatment of various neurological and psychiatric conditions, such as Parkinson's disease, migraine, and depression.

However, ergolines can also have significant side effects, including hallucinations, nausea, and changes in blood pressure. In addition, some ergot alkaloids have been associated with a rare but serious condition called ergotism, which is characterized by symptoms such as muscle spasms, vomiting, and gangrene. Therefore, the use of ergolines must be carefully monitored and managed to ensure their safety and effectiveness.

Some specific examples of drugs that contain ergolines include:

* Dihydroergotamine (DHE): used for the treatment of migraine headaches
* Pergolide: used for the treatment of Parkinson's disease
* Cabergoline: used for the treatment of Parkinson's disease and certain types of hormonal disorders

It is important to note that while ergolines have shown promise in some therapeutic areas, they are not without their risks. As with any medication, it is essential to consult with a healthcare provider before using any drug containing ergolines to ensure that it is safe and appropriate for an individual's specific needs.

Cyclic peptides are a type of peptides in which the N-terminus and C-terminus of the peptide chain are linked to form a circular structure. This is in contrast to linear peptides, which have a straight peptide backbone with a free N-terminus and C-terminus. The cyclization of peptides can occur through various mechanisms, including the formation of an amide bond between the N-terminal amino group and the C-terminal carboxylic acid group (head-to-tail cyclization), or through the formation of a bond between side chain functional groups.

Cyclic peptides have unique structural and chemical properties that make them valuable in medical and therapeutic applications. For example, they are more resistant to degradation by enzymes compared to linear peptides, which can increase their stability and half-life in the body. Additionally, the cyclic structure allows for greater conformational rigidity, which can enhance their binding affinity and specificity to target molecules.

Cyclic peptides have been explored as potential therapeutics for a variety of diseases, including cancer, infectious diseases, and neurological disorders. They have also been used as tools in basic research to study protein-protein interactions and cell signaling pathways.

A chromophobe adenoma is a type of benign (non-cancerous) tumor that typically arises in the pituitary gland, which is a small endocrine gland located at the base of the brain. The term "chromophobe" refers to the appearance of the cells under a microscope - they lack pigment and have a characteristic appearance with abundant clear or lightly stained cytoplasm.

Chromophobe adenomas are slow-growing tumors that can vary in size, and they may cause symptoms due to pressure on surrounding structures or by producing excess hormones. The most common hormone produced by chromophobe adenomas is prolactin, leading to symptoms such as menstrual irregularities, milk production (galactorrhea), and decreased sexual function in women, and decreased libido, erectile dysfunction, and infertility in men.

Treatment for chromophobe adenomas typically involves surgical removal of the tumor, often through a transsphenoidal approach (through the nose and sphenoid sinus). In some cases, radiation therapy or medical management with hormone-blocking drugs may also be necessary. Regular follow-up with an endocrinologist is important to monitor for any recurrence or hormonal imbalances.

A prolactinoma is a type of pituitary tumor that produces an excess amount of the hormone prolactin, leading to various symptoms. The pituitary gland, located at the base of the brain, is responsible for producing and releasing several hormones that regulate different bodily functions. Prolactin is one such hormone, primarily known for its role in stimulating milk production in women during lactation (breastfeeding).

Prolactinoma tumors can be classified into two types: microprolactinomas and macroprolactinomas. Microprolactinomas are smaller tumors, typically less than 10 millimeters in size, while macroprolactinomas are larger tumors, generally greater than 10 millimeters in size.

The overproduction of prolactin caused by these tumors can lead to several clinical manifestations, including:

1. Galactorrhea: Unusual and often spontaneous milk production or leakage from the nipples, which can occur in both men and women who do not have a recent history of pregnancy or breastfeeding.
2. Menstrual irregularities: In women, high prolactin levels can interfere with the normal functioning of other hormones, leading to menstrual irregularities such as infrequent periods (oligomenorrhea) or absent periods (amenorrhea), and sometimes infertility.
3. Sexual dysfunction: In both men and women, high prolactin levels can cause decreased libido and sexual desire. Men may also experience erectile dysfunction and reduced sperm production.
4. Bone loss: Over time, high prolactin levels can lead to decreased bone density and an increased risk of osteoporosis due to the disruption of other hormones that regulate bone health.
5. Headaches and visual disturbances: As the tumor grows, it may put pressure on surrounding structures in the brain, leading to headaches and potential vision problems such as blurred vision or decreased peripheral vision.

Diagnosis typically involves measuring prolactin levels in the blood and performing imaging tests like an MRI (magnetic resonance imaging) scan to assess the size of the tumor. Treatment usually consists of medication to lower prolactin levels, such as dopamine agonists (e.g., bromocriptine or cabergoline), which can also help shrink the tumor. In some cases, surgery may be necessary if medication is ineffective or if the tumor is large and causing severe symptoms.

Hyperprolactinemia is a medical condition characterized by abnormally high levels of prolactin, a hormone produced by the pituitary gland. In women, this can lead to menstrual irregularities, milk production outside of pregnancy (galactorrhea), and infertility. In men, it can cause decreased libido, erectile dysfunction, breast enlargement (gynecomastia), and infertility. The condition can be caused by various factors, including pituitary tumors, certain medications, and hypothyroidism. Treatment typically involves addressing the underlying cause and may include medication to lower prolactin levels.

The pituitary gland is a small, endocrine gland located at the base of the brain, in the sella turcica of the sphenoid bone. It is often called the "master gland" because it controls other glands and makes the hormones that trigger many body functions. The pituitary gland measures about 0.5 cm in height and 1 cm in width, and it weighs approximately 0.5 grams.

The pituitary gland is divided into two main parts: the anterior lobe (adenohypophysis) and the posterior lobe (neurohypophysis). The anterior lobe is further divided into three zones: the pars distalis, pars intermedia, and pars tuberalis. Each part of the pituitary gland has distinct functions and produces different hormones.

The anterior pituitary gland produces and releases several important hormones, including:

* Growth hormone (GH), which regulates growth and development in children and helps maintain muscle mass and bone strength in adults.
* Thyroid-stimulating hormone (TSH), which controls the production of thyroid hormones by the thyroid gland.
* Adrenocorticotropic hormone (ACTH), which stimulates the adrenal glands to produce cortisol and other steroid hormones.
* Follicle-stimulating hormone (FSH) and luteinizing hormone (LH), which regulate reproductive function in both males and females.
* Prolactin, which stimulates milk production in pregnant and lactating women.

The posterior pituitary gland stores and releases two hormones that are produced by the hypothalamus:

* Antidiuretic hormone (ADH), which helps regulate water balance in the body by controlling urine production.
* Oxytocin, which stimulates uterine contractions during childbirth and milk release during breastfeeding.

Overall, the pituitary gland plays a critical role in maintaining homeostasis and regulating various bodily functions, including growth, development, metabolism, and reproductive function.

Macroglossia is a medical term that refers to an abnormally large tongue in relation to the size of the oral cavity. It can result from various conditions, including certain genetic disorders (such as Down syndrome and Beckwith-Wiedemann syndrome), hormonal disorders (such as acromegaly), inflammatory diseases (such as amyloidosis), tumors or growths on the tongue, or neurological conditions. Macroglossia can cause difficulties with speaking, swallowing, and breathing, particularly during sleep. Treatment depends on the underlying cause but may include corticosteroids, radiation therapy, surgery, or a combination of these approaches.

The sphenoid bone is a complex, irregularly shaped bone located in the middle cranial fossa and forms part of the base of the skull. It articulates with several other bones, including the frontal, parietal, temporal, ethmoid, palatine, and zygomatic bones. The sphenoid bone has two main parts: the body and the wings.

The body of the sphenoid bone is roughly cuboid in shape and contains several important structures, such as the sella turcica, which houses the pituitary gland, and the sphenoid sinuses, which are air-filled cavities within the bone. The greater wings of the sphenoid bone extend laterally from the body and form part of the skull's lateral walls. They contain the superior orbital fissure, through which important nerves and blood vessels pass between the cranial cavity and the orbit of the eye.

The lesser wings of the sphenoid bone are thin, blade-like structures that extend anteriorly from the body and form part of the floor of the anterior cranial fossa. They contain the optic canal, which transmits the optic nerve and ophthalmic artery between the brain and the orbit of the eye.

Overall, the sphenoid bone plays a crucial role in protecting several important structures within the skull, including the pituitary gland, optic nerves, and ophthalmic arteries.

Hormones are defined as chemical messengers that are produced by endocrine glands or specialized cells and are transported through the bloodstream to tissues and organs, where they elicit specific responses. They play crucial roles in regulating various physiological processes such as growth, development, metabolism, reproduction, and mood. Examples of hormones include insulin, estrogen, testosterone, adrenaline, and thyroxine.

Hypercementosis is a dental condition characterized by an excessive deposition of cementum (a hard, calcified tissue) on the root surface of a tooth. This condition often affects the lower molars and is more commonly found in older individuals. The exact cause of hypercementosis is not fully understood, but it has been associated with chronic inflammation, periodontal disease, and some systemic conditions. In many cases, hypercementosis does not cause any symptoms and may be discovered during routine dental X-rays. However, in severe cases, it can lead to problems such as tooth mobility and displacement. Treatment for hypercementosis is typically not necessary unless it is causing discomfort or other dental issues.

Fibrous Dysplasia, Polyostotic is a rare genetic disorder that affects the bone tissue. It is characterized by the replacement of normal bone tissue with fibrous (scar-like) tissue, leading to weak and fragile bones that are prone to fractures and deformities. The term "polyostotic" refers to the involvement of multiple bones in the body.

In this condition, there is an abnormal development of the bone during fetal growth or early childhood due to a mutation in the GNAS gene. This results in the formation of fibrous tissue instead of normal bone tissue, leading to the characteristic features of Fibrous Dysplasia, Polyostotic.

The symptoms of this condition can vary widely depending on the severity and location of the affected bones. Common symptoms include:

* Bone pain and tenderness
* Bone deformities (such as bowing of the legs)
* Increased risk of fractures
* Skin pigmentation changes (cafe-au-lait spots)
* Hearing loss or other hearing problems (if the skull is affected)

Fibrous Dysplasia, Polyostotic can also be associated with endocrine disorders such as precocious puberty and hyperthyroidism. Treatment typically involves a combination of medications to manage pain and prevent fractures, as well as surgical intervention to correct bone deformities or stabilize fractures.

A Glucose Tolerance Test (GTT) is a medical test used to diagnose prediabetes, type 2 diabetes, and gestational diabetes. It measures how well your body is able to process glucose, which is a type of sugar.

During the test, you will be asked to fast (not eat or drink anything except water) for at least eight hours before the test. Then, a healthcare professional will take a blood sample to measure your fasting blood sugar level. After that, you will be given a sugary drink containing a specific amount of glucose. Your blood sugar levels will be measured again after two hours and sometimes also after one hour.

The results of the test will indicate how well your body is able to process the glucose and whether you have normal, impaired, or diabetic glucose tolerance. If your blood sugar levels are higher than normal but not high enough to be diagnosed with diabetes, you may have prediabetes, which means that you are at increased risk of developing type 2 diabetes in the future.

It is important to note that a Glucose Tolerance Test should be performed under the supervision of a healthcare professional, as high blood sugar levels can be dangerous if not properly managed.

Hormone antagonists are substances or drugs that block the action of hormones by binding to their receptors without activating them, thereby preventing the hormones from exerting their effects. They can be classified into two types: receptor antagonists and enzyme inhibitors. Receptor antagonists bind directly to hormone receptors and prevent the hormone from binding, while enzyme inhibitors block the production or breakdown of hormones by inhibiting specific enzymes involved in their metabolism. Hormone antagonists are used in the treatment of various medical conditions, such as cancer, hormonal disorders, and cardiovascular diseases.

Hypophysectomy is a surgical procedure that involves the removal or partial removal of the pituitary gland, also known as the hypophysis. The pituitary gland is a small endocrine gland located at the base of the brain, just above the nasal cavity, and is responsible for producing and secreting several important hormones that regulate various bodily functions.

Hypophysectomy may be performed for therapeutic or diagnostic purposes. In some cases, it may be used to treat pituitary tumors or other conditions that affect the function of the pituitary gland. It may also be performed as a research procedure in animal models to study the effects of pituitary hormone deficiency on various physiological processes.

The surgical approach for hypophysectomy may vary depending on the specific indication and the patient's individual anatomy. In general, however, the procedure involves making an incision in the skull and exposing the pituitary gland through a small opening in the bone. The gland is then carefully dissected and removed or partially removed as necessary.

Potential complications of hypophysectomy include damage to surrounding structures such as the optic nerves, which can lead to vision loss, and cerebrospinal fluid leaks. Additionally, removal of the pituitary gland can result in hormonal imbalances that may require long-term management with hormone replacement therapy.

Endocrine surgical procedures refer to the surgical removal or manipulation of endocrine glands or related structures. Endocrine glands are specialized organs that produce, store, and secrete hormones directly into the bloodstream. These hormones regulate various physiological processes in the body, including metabolism, growth, development, and reproduction.

Some common endocrine surgical procedures include:

1. Thyroidectomy: Surgical removal of all or part of the thyroid gland, which is located in the neck and produces hormones regulating metabolism. Indications for thyroidectomy may include thyroid cancer, benign thyroid nodules, hyperthyroidism, and Graves' disease.
2. Parathyroidectomy: Surgical removal of one or more parathyroid glands, which are located near the thyroid gland and regulate calcium levels in the blood. Indications for parathyroidectomy may include hyperparathyroidism, parathyroid tumors, and kidney stones caused by high calcium levels.
3. Adrenalectomy: Surgical removal of one or both adrenal glands, which are located on top of the kidneys and produce hormones regulating stress response, metabolism, and blood pressure. Indications for adrenalectomy may include adrenal cancer, pheochromocytoma, Cushing's syndrome, and Conn's syndrome.
4. Pancreatectomy: Surgical removal of all or part of the pancreas, which is a gland located behind the stomach and produces hormones regulating blood sugar levels (insulin and glucagon) and enzymes for digestion. Indications for pancreatectomy may include pancreatic cancer, chronic pancreatitis, and insulinoma.
5. Neuroendocrine tumor resection: Surgical removal of neuroendocrine tumors, which are rare tumors that arise from hormone-producing cells in various organs, including the pancreas, lung, and gastrointestinal tract. Indications for neuroendocrine tumor resection may include symptoms caused by hormone excess or risk of metastasis.

These surgical procedures are complex and require specialized training and expertise. Patients should consult with a qualified surgeon to discuss the risks and benefits of each procedure and determine the best course of treatment.
