The fractures of base of the skull

The fractures of base of the skull accompanied by rupture of a leg of a pituitary body, can cause development and a panhypopituitarism. It is recently described 7 patients who are in a coma at whom level has been lowered in plasma , 4, , and Testosteron-Depotum, and at 6 from them fractures of bones of a skull with subdural hematomas or without them have been taped. After an exit from a coma level of Testosteron-Depotum and 4 in plasma colchicine buy was normalised. Application of the big doses of dexamethasone, however, could affect results during a coma and steroid cancellation at condition improvement, that in certain degree leaves opened a question on the reason of endocrine disturbances [13]. Internal hydrocephaly Changes of endocrine functions were observed and at an internal hydrocephaly [15, 16], they varied from a primary amenorrhea, depression of braking effect of dexamethasone and absence of reaction to an insulinic hypoglycaemia to a panhypopituitarism. At some patients reduction of expression of a hydrocephaly was accompanied by normalisation of endocrine disturbances. Vascular pathology Vascular damages to a hypothalamus are caused usually by rupture an aneurysm forward or back arteries. Hemorrhagic damages [17] were observed both ischemic, and. Microhemorrhages in and kernels became perceptible also. Though there are no publications about results of research of secretion of a vasopressin at such patients, at patients with subarachnoidal hemorrhages observed reaction disturbance on and disappearance of a daily rhythm of secretion of a hydrocortisone [18]. The damages caused by an irradiation Radial therapy concerning intracranial neoplasms (, ependymomas, medulloblastomas and pituitary body tumours),
and also concerning a cancer of a nasopharynx and genyantrums can cause occurrence of signs and hypopituitarism symptoms. The interval between an irradiation and development of hormonal insufficiency fluctuates from 1 year till 10 years and more. The growth inhibition with depression of reaction , a hypogonadotrophic hypogonadism and a hypothyrosis was observed, and conservation at some patients of reaction hormones on stimulation by rilizing-factors specified that a damage place was the hypothalamus. Children, apparently, are more sensitive to an irradiation, than adults, and a critical dose at them consider about 40 Dzh/kg [19]. Other implications of a radiative necrosis include a papilledema, a dementia and local neurologic signs. At some patients observed development of sarcomas. Till now there are no reports that the standard preventive irradiation of area go - (240 Dzh/kg) at children with causes any changes of neurologic indicators though long observations over neuroendocrinal functions were spent only in the limited number of cases. While there is no other treatment of hormonal insufficiency, except replaceable therapy. DISTURBANCES OF FUNCTIONS OF THE PITUITARY BODY OWING TO THE HYPOTHALAMUS PATHOLOGY Hypothalamus dysfunction can result both to quantitative, and in qualitative change of secretion of hormones of a pituitary body. Earlier published ultracet online reports on the endocrine disturbances bound to tumours of a hypothalamus [20], concerned in The-core to and to disturbances of function of sexual glands (usually a hypogonadism at damage of a forward hypothalamus or premature sexual development at a lesion of a back hypothalamus or an epiphysis). In many of these cases safety of histology and pituitary body function was not checked. Secretion depression the hormones, caused by disturbance influences, can imitate a hypopituitarism though its expression usually is less, than at a primary lesion of a pituitary body. However at the patient with the bronchogenic cancer of lungs metastasizing in radical lymphonoduses and a brain, observed a panhypopituitarism [21]. At autopsy not changed pituitary body has been found out, but at a hypothalamus was present two small a hemorrhagic necrosis in diameter of 2-3 mm located on either side of III ventricle immediately over a median eminence. Secretion intensifying hormones is registered mainly concerning , Prolactinum, Adrenocorticotrophinum () and a vasopressin, and not always it is possible to differentiate these cases from a primary pathology of a pituitary body. In process of revealing of patterns of subthalamic regulation of function of a forward share of a pituitary body it became clear, that endocrine disturbances can be shown not only change of initial level of hormones, but also feedback disturbance, secretion or circadian periodicity (that is clinically less obvious). From here follows, that disturbance of regulation of endocrine functions from party TSNS can proceed without obvious signs of change of activity of endocrine system.
