[Kallman's syndrome combined with aortic valve anomaly and epilepsy].

Kallman's syndrome is defined clinically as hypogonadotropic hypogonadism associated with anosmia and other congenital abnormalities. There is no report on Kallman's syndrome coexisting with aortic valve anomaly and epilepsy in the available literature. Therefore, the authors considered worthy presenting a case of a 36-years male [correction of female] patient with Kallmann's syndrome combined with aortic valve anomaly, epilepsy and hyperostosis frontalis. Disease history data, clinical examination, the results of hormonal tests and USG helped to establish the diagnosis. Diagnostic and therapeutical problems in such cases have also been discussed.

Pharmacokinetic parameters of thiamazole in hyperthyroid patients responding rapidly and slowly to the treatment.

Pharmacokinetic parameters of thiamazole were compared in two groups of patients with hyperthyroidism due to Graves-Basedow disease, differing in the period required to achieve clinical euthyrosis (less than 28 days, group R, n = 23, and not less than 35 days, group D, n = 18) after treatment with the "full" dose of the drug. The drug absorption from the GI tract in both groups was similar, but the serum concentrations of the drug (Cmax and AUC) were higher, and distribution volume and total clearance lower in the R than in D group. No evidence was found for the importance of initial plasma levels of thyroxine or triiodothyronine on pharmacokinetic parameters of thiamazole.

[Pharmacokinetics of phenazone in patients with fast and slow euthyroidism after methimazole treatment].

Hyperthyroidic patients treated with methimazole were retrospectively divided into two groups, depending on the period of time required for euthyreosis: these attaining euthyreosis up to 28 days of therapy (A) and these in whom thyroid gland functioning is normalized after a 35-day therapy with full dose of methimazole (B). The study aimed at investigating whether clinical euthyreosis is related to the activity of microsomal enzymes in the liver using phenazone elimination test for this purpose. Phenazone elimination test was performed just before the treatment and after 8 weeks of methimazole administration. A decrease in kel and Clt as well as an increase in AUC were noted. These changes were more pronounced in patients of group A than those of group B. It might be concluded that phenazone pharmacokinetics is different in patients quickly attaining euthyreosis. The difference is probably due to the difference in biotransformation of methimazole in the liver in which microsomal enzymes play some role.

[Cytoplasmic islet-cell antibodies (ICA) and cytoplasmic complement- fixing antibodies (CF-ICA) in patients with newly detected and short-lasting diabetes mellitus type 1].

The study aimed at assessing ICA and CF-ICA in the serum of patients with newly diagnosed and short-lasting diabetes mellitus type 1. Sixty patients with newly diagnosed diabetes type 1 (39 patients) and short-lasting diabetes of the same type (21 patients) aged between 2 and 34 years were classified. Anti-islet antibodies were detected with indirect immunoflourescence in specimens of fresh, frozen human pancreast in the tested group ICA were found in 53% of cases. At the time of diagnosis, ICA were found in 76% of children and in 14% of adult patients whereas respective data for diabetes mellitus lasting up to 2 years were 40% and 64%. Complement-fixing islet cytoplasmatic antibodies were found only in patients with ICA (47% of such cases). These antibodies were found in children with newly diagnosed diabetes mellitus (36%). In case of adults CF-ICA were detected in 7% of newly diagnosed diabetes mellitus cases and in 45% of cases with the disease lasting for 2 years. Titres of ICA ranged from 1:1 to 1:128 whereas titres CF-ICA from 1:1 to 1:8. No correlation between ICA titre and CF-ICA titre was noted.

[Effect of furosemide on the plasma level of atrial natriuretic peptide (ANP) in healthy persons and in patients with uncomplicated primary arterial hypertension].

The study included 15 healthy individuals aged 37.3 +/- 7.7 years and 27 patients with the primary uncomplicated blood hypertension (stages I and II according to WHO classification) of the comparable age, untreated and given a diet containing 100-120 nM Na+ daily. Plasma ANP concentrations were measured prior to and after 30, 60, and 90 minutes following 40 mg furosemide intravenously. An increase in 1-minute urine output and 1-minute Na+ excretion in the urine were determined during 90 minutes following furosemide administration. A significant decrease in ANP plasma levels was noted in all examined individuals following furosemide administration in all time intervals comparing with baseline values. An increase in 1-minute urine output and 1-minute sodium excretion with the urine significantly correlated with plasma ANP decrease during 90 minutes following furosemide administration. The obtained results suggest that furosemide inhibits ANP secretion in the patients with uncomplicated primary hypertension similarly to healthy individuals.

[Diagnostic value of electrophysiologic studies in diabetics in our experience].

Twenty two patients (44 eyes) with diabetes of the type I aged 18-60 were examined. Duration of diabetes--at least 10 years. Performed were routine ophthalmological, general medical and electrophysiological examinations (EOG, ERG, with registration of oscillatory potentials, visual evoked potentials). It was evidenced that the most accurate method demonstrating the disturbances of the retinal function--independently of the visual acuity, fundus changes and other signs and complications--are the oscillatory potentials. Evoked visual potentials enable us in a majority of cases to evidence the central and subclinical disturbances of the optic nerve.
