Some teratomas can be transformed

Some teratomas can be transformed to cranyopharyngiomas and cosecrete in chorionic Gonadotropinum. Since the first report on premature puberty at the boy with a tumour of an epiphysis [69], communication of these phenomena causes appreciable interest, but at an objective view it is possible to conclude, that only small percent skelaxin 800 of such tumours causes premature puberty [70, 71]. As a rule, it is observed only at tumours which extend far beyond epiphysis area, and the reason of endocrine disturbances, most likely, is the destruction of other areas of a brain which in the period have tonic brake an effect on secretion LG-RG and Gonadotropinums. Not parenchymatous tumours of an epiphysis are more often accompanied by premature puberty, than parenchymatous [72], and on this basis consider, that the destruction of an epiphysis a tumour leads to the termination of secretion of any product (possibly, , or any other factor) which in norm the puberty beginning brakes. There are also indicatings on the endocrine function, at least some tumours of an epiphysis, and production them of the antigonadotrophic factor could be one of explanations of often observable delay of puberty. Preliminary data, however, do not contain indicatings on level rising in blood at patients with pinealomas. Though the further researches are necessary for the decision of this question, it is quite possible to admit existence of plural mechanisms of disturbance of sexual function at patients with epiphysis tumours.
By the moment of occurrence of clinical semiology and an establishment of the diagnosis the majority of tumours of an epiphysis appears already inoperable. For specification of character of a lesion of a tissue the craniotomy if the tumour belongs to type of germinomas can be demanded, with success radial therapy is applied. BRAIN PSEUDONEOPLASM This syndrome known also under the name of a good-quality intracranial hypertensia, is characterised by a headache, a papilledema and rising of intracranial pressure for lack of focal damages or an obstructive hydrocephaly. In most cases illness develops , and in 90 of cases - at corpulent women [74]. The disease beginning usually acute, and at 35 of patients appears a headache or sight disturbances such, as sudden loss or misting of sight or a diplopia. Can become perceptible also drowsiness and . Spontaneous treatment meets in 25 of cases. In other cases disease recovers or robaxin muscle relaxer only after repeated spinal punctures, or after their application in a combination to corticosteroid therapy. At small percent of patients observed communication of this disease with obstruction of venous sine, an intoxication vitamin A, an iron deficiency anaemia, cancellation of steroid therapy, illness, pregnancy or reception of contraceptives. In some cases, especially at long existence of symptoms, the augmentation of a Turkish saddle with signs of an "empty" saddle became perceptible. Results of the endocrinologic researches including definition of initial level of Prolactinum, , and , and also reactions of a hydrocortisone and on an insulinic hypoglycaemia, circadian fluctuations, concentration of corticosteroids and hydrocortisone reaction on , have appeared within norm though in one of researches reaction change on has been noted, normalised during remission [75]. CEREBRAL GIGANTISM This disease of children's age is characterised by growth acceleration (though final growth usually does not exceed normal borders), augmentation of osteal age, absence of changes of a Turkish saddle and not progressing mental retardation [76]. At a pneumoencephalography find out expansion of ventricles without signs of focal lesions . Results of definition of initial function of glands of internal secretion remain within norm; it is not observed risings of level in plasma though researches of its secretion throughout days were not spent. The variants of this condition bound to a lipodystrophy, pigmentation, a hypertrichosis, , by egestion rising 17-KS and 17-ketogennyh steroids, tolerance disturbance to a glucose, a lipidemia and in one case with rising of insulinoid activity of plasma [77] are described also. The cerebral gigantism in these cases differs, possibly, and from a gigantism observed at a neurofibromatosis (with involving in hypothalamus process) [78] at which paradoxical hypersecretion [79 is described, 80]. CHOREA In a hypothalamus sick of chorea observe pathological changes [81, 82]. Some authors consider as a cause of illness metabolism disturbance substances [83], others do not confirm this point of view [84]. A number of researches of initial both stimulated levels and Prolactinum is spent. Rising of initial concentration of
