(3) This case was diagnosed as the Sotos syndrome based on the following symptoms and findings, acromegaloid features, hypertrophic changes in the hands and feet, a history of epileptic episodes, a low IQ, a normal growth hormone value, and no tumor lesion in the pituitary gland.
(4) These GH values and responses helped to differentiate acromegaloidism from treated and untreated acromegaly.
(5) Affected persons have a progressively coarse, acromegaloid-like facial appearance and thickening of the lips and intraoral mucosa.
(6) Children with Sotos syndrome have growth acceleration, macrocephaly, acromegaloid features and delay in neuropsychomotor development during infancy.
(7) Acromegaloidism is a condition which resembles acromegaly by its clinical manifestations but is not due to pituitary or hypothalamic dysfunction.
(8) It has been proposed that the acromegaloid features result from the interaction of insulin at concentrations encountered in vivo, with a functionally intact insulin-like growth factor-I (IGF-I) receptor closely related to the insulin receptor.
(9) In 37 patients with endosellar pituitary adenoma attended by the acromegaloid syndrome, a plasma STH level determined by a radioimmunoassay against a background of an insulin test was compared with EEG findings before and at varying time (up to 7 yrs.)
(10) The pathogenesis of acromegaloidism was not determined, but somatomedin studies may prove helpful in further defining this disorder.
(11) The data suggest that over a short period of time the relatively high doses of growth hormone given in TS are unlikely to induce acromegaloid hand growth.
(12) These in vitro data do not explain the acromegaloid features observed in vivo, suggesting that acromegaloid features are mediated by other mechanisms.
(13) The five affected persons showed a striking resemblance to the patients previously reported, including progressively coarse acromegaloid-like facial appearance, narrow palpebral fissures, bulbous nose, and thickening of the lips and intraoral mucosa, resulting in exaggerated rugae and frenula.
(14) In this report we describe the first case of a girl with acromegaloidism in Japan.
(15) We conclude that in some patients with acanthosis nigricans and acromegaloid features, IGF-I receptors of cultured fibroblasts may share the inherent defects of insulin receptor function.
Acromegaly
Definition:
(n.) Chronic enlargement of the extremities and face.
Example Sentences:
(1) The changes in cell mass, body fat and extracellular water observed in acromegaly suggest different dose-response relationships between GH and these parameters.
(2) Biochemical evaluation demonstrated characteristic changes typical of acromegaly, and an unusual pattern of delayed somatotropin response to hGHRH40, not previously described in this syndrome.
(3) We have attempted to investigate a relationship between the paradoxical GH secretion with the abnormal glucose tolerance test present in some cases of acromegaly.
(4) Body composition determination by bioelectrical impedance analysis (BIA) has been compared with measurement of total body water (TBW) by tritiated water dilution and estimation of body fat (BF) by measurement of TBW and total body potassium (TBK) in a four-compartment model, in patients with acromegaly.
(5) Thus, lack of response to exogenous GHRH in untreated acromegaly may indicate the presence of an ectopic GHRH producing tumor.
(6) Immunoreactive digoxin-like substance was determined in 52 subjects: 17 healthy ones, 15 patients with essential hypertension, 10 cases of chronic renal failure and 10 patients with acromegaly.
(7) In this situation, insulin binding at low hormone concentrations was further reduced to one-half of that in the control group, and the sensitivity of insulin-induced antilipolysis was markedly decreased in acromegaly.
(8) Ectopic GHRH is a relatively uncommon cause of acromegaly, which should be differentiated from pituitary adenoma, in order to avoid damage to the pituitary gland from unnecessary interventions.
(9) At the pituitary level, it has been shown that the number of binding sites was negatively correlated to growth hormone levels in acromegaly.
(10) We measured 695 sera obtained in short stature children (GH deficiency or normal GH secretory) and adults (normal, hypopituitarism or acromegaly).
(11) Acromegaly is caused by GH-secreting pituitary adenomas and, in rare cases, by ectopic production of GRH with resultant hypersecretion of GH.
(12) We conjecture that postmenopausal and involutional osteoporosis were far advanced before the development of acromegaly, explaining the coexistence of the two conditions.
(13) In conclusion, SMS is a useful clinical tool for treatment of acromegaly, and a multiple sc injection method seems to be preferable.
(14) A patient with acromegaly was shown to have obstructive sleep apnoea by polygraphic recordings.
(15) A young woman presented with acromegaly and amenorrhea-galactorrhea with hypersomatotropinemia and hyperprolactinemia.
(16) The authors report 3 cases of acromegaly diagnosed while the patients were in hospital for cardiovascular disease: arterial hypertension in two and hypertrophic myocardiopathy in all three.
(17) Serum-prolactin concentrations were measured in 111 patients who had radiological abnormalities of the pituitary but no evidence of acromegaly, Cushing's syndrome, or Nelson's syndrome.
(18) There was no difference in diastolic function between patients with active acromegaly and those with treated acromegaly.
(19) The increased risk of colon cancer in acromegaly is consistent with previous clinical reports and suggests opportunities for etiologic research and early cancer detection.
(20) We have observed an apparent hypoglobulinemia in 17 of 35 patients (48.6%) with acromegaly.
