(Dorland, 27th ed)Histamine Release: The secretion of histamine from mast cell and basophil granules by exocytosis. This can be initiated by a number of factors, all of which involve binding of IgE, cross-linked by antigen, to the mast cell or basophil's Fc receptors. Once released, histamine binds to a number of different target cell receptors and exerts a wide variety of effects.Adenoma, Villous: An adenoma of the large intestine.

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.Adrenocortical Adenoma: A benign neoplasm of the ADRENAL CORTEX. It is characterized by a well-defined nodular lesion, usually less than 2.5 cm. Most adrenocortical adenomas are nonfunctional. The functional ones are yellow and contain LIPIDS.

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)Cell Degranulation: The process of losing secretory granules (SECRETORY VESICLES). This occurs, for example, in mast cells, basophils, neutrophils, eosinophils, and platelets when secretory products are released from the granules by EXOCYTOSIS.Cushing Syndrome: A condition caused by prolonged exposure to excess levels of cortisol (HYDROCORTISONE) or other GLUCOCORTICOIDS from endogenous or exogenous sources. It is characterized by upper body OBESITY; OSTEOPOROSIS; HYPERTENSION; DIABETES MELLITUS; HIRSUTISM; AMENORRHEA; and excess body fluid. Endogenous Cushing syndrome or spontaneous hypercortisolism is divided into two groups, those due to an excess of ADRENOCORTICOTROPIN and those that are ACTH-independent.Filarioidea: A superfamily of nematodes of the suborder SPIRURINA. Its organisms possess a filiform body and a mouth surrounded by papillae.Genes, APC: Tumor suppressor genes located in the 5q21 region on the long arm of human chromosome 5.

Most of these drugs act by preventing the release of inflammatory mediators or inhibiting the actions of released mediators on their target cells. (From AMA Drug Evaluations Annual, 1994, p475)Hyperparathyroidism: A condition of abnormally elevated output of PARATHYROID HORMONE (or PTH) triggering responses that increase blood CALCIUM. It is characterized by HYPERCALCEMIA and BONE RESORPTION, eventually leading to bone diseases. PRIMARY HYPERPARATHYROIDISM is caused by parathyroid HYPERPLASIA or PARATHYROID NEOPLASMS.

An R201H activating mutation of the GNAS1 (Gsalpha) gene in a corticotroph pituitary adenoma. (1/9)

In the pituitary gland, activating mutations of the GNAS1 (Gsalpha) gene at Gln227 have been identified in adrenocorticotrophin secreting, growth hormone secreting, and prolactin secreting adenomas. To date, mutations at the codon encoding R201, typically underlying the McCune-Albright syndrome and isolated fibrous dysplasia of bone, have been demonstrated only in growth hormone secreting pituitary adenomas. In this study, a polymerase chain reaction amplified target sequence in exon 8 of the GNAS1 gene was sequenced, identifying the first R201 mutation seen in an isolated basophilic adenoma which generated Cushing's disease in a child. This case adds Cushing's disease to the range of human diseases caused by R201 mutations of the GNAS1 gene.  (+info)

A 2-year dose-response study of lesion sequences during hepatocellular carcinogenesis in the male B6C3F(1) mouse given the drinking water chemical dichloroacetic acid. (2/9)

Dichloroacetic acid (DCA) is carcinogenic to the B6C3F(1) mouse and the F344 rat. Given the carcinogenic potential of DCA in rodent liver and the known concentrations of this compound in drinking water, reliable biologically based models to reduce the uncertainty of risk assessment for human exposure to DCA are needed. Development of such models requires identification and quantification of premalignant hepatic lesions, identification of the doses at which these lesions occur, and determination of the likelihood that these lesions will progress to cancer. In this study we determined the dose response of histopathologic changes occurring in the livers of mice exposed to DCA (0.05-3.5 g/L) for 26-100 weeks. Lesions were classified as foci of cellular alteration smaller than one liver lobule (altered hepatic foci; AHF), foci of cellular alteration larger than one liver lobule (large foci of cellular alteration; LFCA), adenomas (ADs), or carcinomas (CAs). Histopathologic analysis of 598 premalignant lesions revealed that (a)) each lesion class had a predominant phenotype; (b)) AHF, LFCA, and AD demonstrated neoplastic progression with time; and (c)) independent of DCA dose and length of exposure effects, some toxic/adaptive changes in non-involved liver were related to this neoplastic progression. A lesion sequence for carcinogenesis in male B6C3F(1) mouse liver has been proposed that will enable development of a biologically based mathematical model for DCA. Because all classes of premalignant lesions and CAs were found at both lower and higher doses, these data are consistent with the conclusion that nongenotoxic mechanisms, such as negative selection, are relevant to DCA carcinogenesis at lower doses where DCA genotoxicity has not been observed.  (+info)

Analysis of pituitary hormones and chromogranin A mRNAs in null cell adenomas, oncocytomas, and gonadotroph adenomas by in situ hybridization. (3/9)

To study the relationship between null cell adenomas, oncocytomas and gonadotroph adenomas, we analyzed 32 surgically removed formalin-fixed paraffin-embedded pituitary tumors for the expression of pituitary hormone messenger RNAs (mRNAs) by in situ hybridization (ISH). Most tumors were also analyzed for chromogranin A mRNA. To identify the cell type constituting the tumors and to assess hormone content, all tumors were investigated by histology, transmission electron microscopy and immunohistochemistry. Most null cell adenomas (6/11) and gonadotroph adenomas (9/10) expressed the mRNAs for alpha-subunit of glycoprotein hormones whereas only 2/11 oncocytomas expressed alpha-subunit mRNA. FSH beta and/or LH beta mRNA were present in most null cell and gonadotroph adenomas but only in a few oncocytomas. Prolactin (PRL) mRNA was detected in two null cell tumors and in one gonadotroph adenoma, whereas GH and POMC mRNA were present in one null cell adenoma. Chromogranin A mRNA, which codes for the major secretory granule protein, was present in 25/26 tumors including all tumors that were negative for pituitary hormone mRNAs, indicating adequate preservation of specific mRNA transcripts in the paraffin-embedded sections of tumor cells. These results indicate that null cell adenomas and gonadotroph adenomas are closely related neoplasms and that oncocytomas may represent a functionally defective form of null cell adenoma characterized by mitochondrial abundance, which has retained the capacity to synthesize the major secretory granule protein chromogranin A. Although the cytogenesis of null cell adenomas and oncocytomas is not clear, it can be suggested that these two tumor types are derived from a pluripotential precursor cell that is capable of undergoing multidirectional differentiation and synthesizing various hormones, mainly glycoproteins.  (+info)

Transcranial management of pituitary tumours with suprasellar extension. (4/9)

A consecutive series of 101 pituitary tumours treated in the 10 year period 1968-78 has been examined, giant lesions being excluded. There were 48 female cases and 53 male, women predominating in the ratio of three to two in the age group 40-50 years and men showing a slight predominance in the age group 50-60 years. Most cases presented with visual deterioration which in 22 cases had been present for between one and two years, and in a further 22 for an even longer period, between two and 10 years. All patients underwent subfrontal craniotomy with mainly radical excision of the tumour followed by radiotherapy. The operative mortality was 0.99%. A system of grading of visual field defect has been described and used to compare preoperatively visual loss with postoperative visual recovery. Fifty-six per cent of cases returned to normal vision over the first two years, and a further 37% showed appreciable improvement in visual fields or acuity or both. Six per cent of cases showed no improvement in visual fields, and one patient died of postoperative deep vein thrombosis and pulmonary embolism. The degree of visual improvement has been correlated with the extent of visual defect, length of visual complaint, and size of the tumour. The importance of central and peripheral visual field analysis is emphasised yet again.  (+info)

Gonadotroph adenomas of the human pituitary: sex-related fine-structural dichotomy. A histologic, immunocytochemical, and electron-microscopic study of 30 tumors. (5/9)

Thirty pituitary tumors, removed from 14 men and 15 women, were diagnosed as gonadotroph adenomas on the basis of their immunocytochemical and/or ultrastructural features. Serum follicle-stimulating hormone (FSH), but not luteinizing hormone (LH), was elevated in 8 men, whereas none of the women had gonadotropin levels, as measured by radioimmunoassay, inappropriately high for their age. Immunoreactive FSH (sometimes also LH) was present in 13 of 15 tumors in men but only 6 of 13 adenomas in women. By electron microscopy, gonadotroph adenomas in men had uncharacteristic features often similar to those of null-cell adenomas with poorly or moderately developed cytoplasmic organelles. In women, all tumors were well differentiated, with a highly distinctive vesicular dilatation of the Golgi complex ("honeycomb Golgi") as a diagnostic marker present in 14 of 15 adenomas. To the author's knowledge, this is the first example of sex-linked dichotomy within a tumor type expressed as the markedly different ultrastructural appearance of cytoplasmic organelles, especially the Golgi apparatus.  (+info)

Cytoplasmic filaments of Crooke's hyaline change belong to the cytokeratin class. An immunocytochemical and ultrastructural study. (6/9)

Crooke's hyaline change was studied by immunocytochemistry using an anti-adrenocorticotropic hormone (ACTH) antiserum and five different antisera against cytokeratins. Crooke's hyaline appears in basophil cells of the adenohypophysis in patients with hypercortisolism, presumably as a part of the negative feedback on corticotropin secretion. Previous studies have identified the hyaline material as a simple protein, apparently unrelated to ACTH, and electron microscopy has revealed a loss of secretory granules and an accumulation of 6-9-nm filaments in the cytoplasm of affected cells. In this study, the secretory granules in adenohypophysial cells exhibiting Crooke's hyaline change were labeled by anti-ACTH antibodies, while the hyaline material was positive for cytokeratin with each of the five antisera used. The results suggest that high levels of glucocorticoids may stimulate elaboration of cytokeratins in basophils while they suppress the production and release of ACTH.  (+info)

Silent corticotropic adenomas of the human pituitary gland: a histologic, immunocytologic, and ultrastructural study. (7/9)

Among 300 surgically removed pituitary adenomas, 17 tumors containing immunoreactive 1-39 adrenocorticotropin (ACTH) and/or 19-39 ACTH, beta-lipotropin, and alpha-endorphin but unassociated with clinical signs of Cushing's disease have been detected. These neoplasms were divided into basophilic adenomas with strong periodic acid-Schiff (PAS) and lead-hematoxylin positivity and chromophobic tumors with moderate or no PAS and lead-hematoxylin positivity. The former were densely granulated tumors with a fine structure strikingly similar to that of functioning corticotropic cell adenomas. The latter were sparsely granulated with varying ultrastructural patterns. The marked morphologic diversity suggests that these adenomas, despite their similar immunocytologic characteristics, represent more than one entity. Clinically, the most common finding was a rapidly progressing visual defect. An unusually high incidence of infarction (5 cases) and recurrence (5 cases) was noted, underlining the importance of correct morphologic diagnosis and careful follow-up.  (+info)

Immunohistochemical and immunoelectron-microscopic study of pituitary adenomas associated with Cushing's disease. A report of 13 cases. (8/9)

Thirteen pituitary adenomas were removed from patients with Cushing's disease by the transphenoidal route. All cases demonstrated a typical histochemical and ultrastructural pattern. Immunocytochemical study by means of the immunoperoxidase technique and light or electron microscopy demonstrated 1-24/1-39 adrenocorticotropic hormone (ACTH) in all cases, lipotropin/melanotropin (beta-LPH/beta-MSH) in 10 cases, beta-endorphin in 8 cases, and an absence of calcitonin in all cases. In addition, in 2 cases tumor tissue contained a few antiprolactin immunoreactive cells. These ACTH, beta-LPH, and beta-endorphin immunoreactivities may reflect either the peptides themselves or their precursors or intermediate products. The authors also suggest a possible intermediate-lobe-like processing of beta-LPH leading to beta-endorphin production, which may act on PRL cells. In addition, no positive arguments for the existence of a common precursor for calcitonin and ACTH could be provided from this study.  (+info)

In the latter half of the year 1895, a German scientist called Roentgen was working in his laboratory at the Physical Institute of the University of Wurzburg, Germany, experimenting with a type of discharge tube called Crookes tube. The tube displayed a fluorescent glow when a high voltage current was passed through it. When he shielded the tube with heavy black cardboard, he found that a greenish fluorescent light could be seen on a fluorescent screen kept some 9 feet away. Roentgen concluded that a new type of ray was emitted from the tube that could pass through the black covering. The rays could pass through most substances, including the soft tissues of the body, but left the bones and most metals visible. One of his earliest photographic plates from his experiments was that of a film of his wife, Berthas hand with a ring. Roentgen named the invisible radiations as X-rays (or unknown rays). ...

Shortly after the entry of the United States into the First World War, Cushing was commissioned as a major in the U.S. Army Medical Corps on May 5, 1917. He was director of the U.S. base hospital attached to the British Expeditionary Force in France. Cushing also served as the head of a surgical unit in a French military hospital outside of Paris. During his time at the French military hospital, Cushing experimented with the use of electromagnets to extract fragments of metallic missile shrapnel that were lodged severely within the brain.[8] He was mentioned in a dispatch by Field Marshal Sir Douglas Haig in November 1917.[9] On June 6, 1918, he was promoted to lieutenant colonel and was assigned as senior consultant in neurological surgery for the American Expeditionary Forces in Europe. He attained the rank of Colonel (O-6) on October 23, 1918.[5] In that capacity, he treated Lieutenant Edward Revere Osler, who was fatally wounded during the third battle of Ypres.

Telomerase reverse transcriptase (TERT) expression is a hallmark in tumorigenesis and upregulated due to mutations and methylation of the human (h)TERT promoter. As mutations are rare but methylation is common in pituitary adenomas (PA), we determined promoter methylation and its clinical impact in 85 primary and 15 recurrent PA by methylation-specific PCR. 40 females (47 %) and 45 males (53 %) with a median age of 53 years harboring micro-, macro-, and giant adenomas in 12, 82, and 6 % were included (prolactinomas, corticotroph, somatotroph, gonadotroph, thyreotroph, plurihormonal, and null cell adenomas in 11, 18, 10, 29, 1, 10, and 21 %, respectively). In primary diagnosed tumors, methylation rate was 27 % and higher in males than in females (40 vs. 13 %, p = 0.001) after uni- and multivariate analyses. Methylation differed among PA subtypes (0-42 %, p = n.s.) and was not significantly correlated with tumor size, cavernous sinus invasion, or serum hormone levels. Ki67 labeling index and ...
