[Thyrotropin-secreting adenomas of the hypophysis].

Thyrotropin secreting pituitary adenomas are scarce. They may cause an extremely rare form of hyperthyroidism. The diagnosis is often delayed because the clinical symptoms are attributed to common types of hyperthyroidism.

[Octreotide in the treatment of thyrotropin-secreting pituitary adenomas].

The authors detected in a 30-year-old patient a very rare type of hyperthyroidism caused by a thyrotropin secreting pituitary adenoma. Scintigraphic examination of the pituitary by means of 111In radiolabelled octreotide revealed an increased accumulation of the radiopharmaceutical preparation in the tumour, which confirmed the high density of somatostatin receptors. After onset of octreotide treatment (Sandostatin, Sandoz, Switzerland) 3 x 100 ug/day by the s.

Comparative screening for thyroid disorders in old age in areas of iodine deficiency, long-term iodine prophylaxis and abundant iodine intake.

Objective: To investigate the effect of varying amounts of iodine intake on the prevalence of thyroid dysfunction, autoimmunity and goitre in old age.

Design: The first screening study where elderly subjects with varying amounts of iodine supply but from the same geographical and ethnographical region (Carpathian basin) were compared, and all hormone measurements and ultrasonography were performed by the same laboratory or person.

Patients: Nursing home residents were screened for thyroid disorders from: (A) an iodine-deficient area, Northern Hungary (n = 119; median age 81 years; median iodine excretion (MIE) 0.

Adrenal incidentalomas--analysis of 23 cases discovered by ultrasound.

Frequent use of abdominal ultrasonography (USG) increases discovery of incidental adrenal tumors. Our experience and concise review of recent opinions on management of adrenal incidentalomas is presented. In four out of 23 patients with adrenal incidentalomas false positivity of USG was found (all on the left side), 4 cases were identified as pseudoadrenal masses.

[Therapeutic approach in patients in hypertensive crisis].

The clinical picture of a hypertensive crisis is not determined only by the blood pressure reading but mainly by the associated symptoms of acute organ damage: neurological, cardiovascular and renal symptoms. The approach to the patient depends on the fact whether an emergency or urgent condition is involved. The authors review at first general principles of treatment of hypertensive crises.
