[Glucagon, growth hormone, and cortisol response to insulin-induced hypoglycemia in insulin-dependent diabetics (IDD) without autonomic neuropathy (author's transl)].

Insulin-induced hypoglycemias are a sign of non-sufficient counterregulation, in which different contra-insulinary hormones participate. The aim of the study was to investigate, whether there exists a difference between IDD and non-diabetics regarding secretion of glucagon, cortisol, and growth hormone during an insulin-induced hypoglycemia and further on pointing out, expecially, the importance of glucagon. Insulin-induced hypoglycemias are counterregulated in non-diabetics, not in IDD.

[Acute hepatic amebiasis (author's transl)].

A case report is given of severe extraintestinal hepatic amebiasis without diarrhea. Formation of an hepatic abscess could be avoided by early institution of appropriate antiamebic treatment, following the diagnosis using sonography and specific serological methods.

[Diagnostic procedures in diencephalo-hypophyseal insufficiency (author's transl)].

A functional diagnosis of the diencephalohypophyseal system was carried out in patients with Sheehan syndrome, chromophobic adenoma, craniopharyngioma, prolactin-producing pituitary tumours, acromegaly, hypothalamo-pituitary dwarfism and constitutional retardation. A combined insulin hypoglycaemia/LH-RH/TSH test was performed to define frequency and extent of anterior pituitary insufficiency. With these illnesses, almost generally, a somatotropic insufficiency (except in acromegaly) was found.
