Panhypopituitarism as first manifestation of a lung cancer

Pituitary metastases of solid tumours are infrequent, specially as a first manifestation. When they happen, they are usually due to breast or lung cancer and are asymptomatic or produce diabetes insipidus. It is very strange that they produce hormonal deficiency. We present a case report of a bronchogenic adenocarcinoma in a 65-year-old man which began with panhypopituitarism, diabetes insipidus and visual alterations. Magnetic resonance imaging revealed a large sellar mass, with clivus infiltration and invading the right cavernous sinus. The biopsy result was adenocarcinoma metastases from lung cancer.     

Erosive gastropathy not associated with duodenal ulcer]

There was a study of 422 in-patient subjects of the therapeutic profile. Endoscopy enabled to discover mucous coat erosions of the antral part of the stomach associated with Helicobacter pylori and absence of ulcer in the anamnesis in 8.7% of them (more frequently in women). As many as 81% of such patients belonged to patients with the ischemic heart disease. Erosive gastropathy is accompanied by the activity of the chronic inflammation response in the duodenum mucous coat that is most evident in IHD patients.     

Surgical treatment of extensive hemangiomas of the liver

The results of treatment of 7 patients with extensive hepatic hemangiomas are analysed. In 6 patients the diagnosis was established before the operation. The liver was resected in 4 patients. One patients with malignant degeneration of the hemangioma was inoperable, in another the hemangioma was not removed because of his old age, and still in another because the process had spread. The authors conclude that in large hemangiomas of the liver in young and middle-aged patients resection of the organ is indicated, especially if there is a destruction cavity and a rapid growth of hemangioma. The operation is not indicated in capillary, surface hemangiomas of a small size, old age of the patient, extension of the process in to the main vascular structures of the other hepatic lobe.     

Use of heparin in the prevention of thrombotic complications in aged oncologic patients

A method for the prevention of thrombotic complications with heparin was developed during examination of 30 elderly and old-aged patients who underwent operation for gastric carcinoma. It was established that the therapeutic activity of heparin in plasma is maintained for 6 hours after a single subcutaneous injection of 5,000 u. Four injections of this dose of heparin ensures its continuous therapeutic activity for 24 hours in elderly oncological patients. Heparin prevention in a daily dose of 20,000 u is safe from the standpoint of hemorrhagic complications. Under clinical conditions, control of plasma heparin activity may be accomplished by means of activated partial thromboplastin time.     

Thyroid stimulating hormone response to thyrotropin in prepubertal depression

In an effort to evaluate whether differences exist in the hypothalamic-pituitary-thyroid axis of depressed children, a thyrotropin releasing hormone (TRH) stimulation test was administered to 55 prepubertal subjects who were divided into three groups matched for age and sex: a depressed group (endogenous N = 15, nonendogenous N = 15), a psychiatric nondepressed control group (N = 16), and a normal control group (N = 9). Each subject was tested at two dosages of TRH, 2 micrograms/kg and 7 micrograms/kg. Increasing age and female sex were positively correlated with a greater thyroid stimulating hormone (TSH) response. TSH response to TRH was examined with subjects reclassified by severe suicidal ideation, severe aggression, and parental history of alcoholism. Results of this study are contrasted with the adult psychiatric literature.     

Long-term cognitive deficits in patients after surgery on aneurysms of the anterior communicating artery.

The long term recovery of a series of 27 patients who had undergone rupture and repair of an aneurysm of the anterior communicating artery was assessed using a number of neuropsychological measures. Testing took place 12 to 84 months post surgery. On the basis of the results from tests of intellect, memory, and conceptual learning, three subgroups of patients were identified: those with persuasive cognitive defects, those with evidence of residual frontal lobe damage and those who showed no evidence of dysfunction. The occurrence of cerebral vasospasm was the most consistent predictor of long term cognitive deficit.
