Neuropsychological functions in the follow-up of transient global amnesia.

Sixteen patients, who had suffered only one episode of transient global amnesia and showed no clinically evident abnormalities in their follow-up, were examined with psychometric and memory tests. Deficits in verbal long-term memory and in verbal IQ were found. These observations seem to demonstrate that in transient global amnesia patients regarded as being 'normal' in their follow-up there is no complete recovery and the sequelae seem to conform to a definite pattern. Problems of nosology and localization are discussed.

Transient hemiballismus and subclavian steal syndrome. Case report.

Transient hemiballismus was observed in a 74-year-old man, displaying subclavian steal syndrome. Such a correlation has not been previously reported in the literature. In this case, transient hemiballismus seemed to depend on hemodynamic factors, but other mechanisms possibly explaining early recovery of the hyperkinesias are discussed. In particular, stress is laid upon the role of preexisting pathological changes of the central nervous system (diffuse cerebral atrophy) associated to the "releasing" lesion.

Analysis of natural corticosteroids in adrenal extracts and in biological fluids by high-performance liquid chromatography.

A liquid chromatographic procedure is described for the analysis of the principal natural corticosteroids in extracts of adrenal glands. Microparticulate silicic acid columns and gradients of methanol in chloroform are used: conditions are described for the quantitative analysis of the single principal steroidal components of adrenal extracts for pharmaceutical use and of adrenal extracts of rats. In the last case, the use of a 5-micron silica column with the appropriate gradient allows the determination of corticosterone and of 18-hydroxydeoxycorticosterone, which were identified by means of mass spectrometry on their eluates. A single analysis can be performed on the extract of 15 mg of rat adrenal tissue. For the last type of analysis, isocratic conditions on a 10-micron LiChrosorb Diol column are also described. The application of the gradient elution procedure to the analysis of steroidal compounds in human plasma is also described.

[Total atrophy of the villi during primary agammaglobulinemia in adults. Therapeutic problems (author's transl)].

A 21-year-old man presented with a 10-year history of a malabsorption syndrome of moderate severity, splenomegaly, and recurrent respiratory infections. Investigations revealed total atrophy of the villi and primary agammaglobulinemia. A gluten-free diet was ineffective. In spite of the absence of lambliasis, treatment with metronidazole produced objective clinical improvement and biological signs of healing of the malabsorption syndrome, but no alteration in the agammaglobulinemia. The authors discuss the relationship between total villous atrophy and primary agammaglobulinemias and the mode of action of metronidazole.

[Doppler observations in migraine patients (author's transl)].

The Authors have subjected 14 migraine patients to Doppler ultrasonic technique. Examinations have been performed on both common carotid arteries, either in headache phase or in pain-free periods. Results in each case suggest variable hemodynamic patterns during migraine attacks. Possible pathogenic mechanisms are discussed.

Testosterone metabolism in basal cell epitheliomas.

In basal cell epitheliomas the testosterone metabolism pattern differs from that of the normal surrounding skin. There is a significant reduction in 5 alpha-reductase activity with a consequent decrease in production of dihydrotestosterone and androstanediols. By contrast the 17 beta-hydroxysteroid dehydrogenase activity shows no consistent change.

[Voluminous hypernephroma of intermittent development. Diagnostic difficulties (author's transl)].

The authors report a case of cancer of the kidney of intermittent development for which nephro-urotomography was negative. They stress the interest of: --preliminary echotomography in patients with palpable masses in the left hypochondrium; --pharmaco-angiography for improved visualization of masses that are only weakly opaque; --a rapid infusion technique, proposed by various authors, which appears to be the most appropriate for the study of this type of mass which is mainly intermittent in its development.

[Hormones and hair growth in man].

A literature review tries to diminish the ambiguity between hormones and hairs. Therefore the hormonal action in general (regulation of the protein synthesis indirectly by enzymatical regulation of the AMP-system or directly by hormones as active metabolites) and the methods to explore hormones-hair-interaction are discussed. Hormones pertaining to the pituitary-adrenal-gonadal axis are regarded as the paramount hormones; therefore the results of research in testosterone, 5-alpha-dihydrotestosterone, estrogens, progesterone, glucocorticoids, the hypophysis and its tropins are recapitulated. The main disorders of hair-growth, pattern baldness and "idiopathic" hirsutism, which would be dependent on a similar disturbance of androgen metabolism, are discussed. Pathology in hair-growth may arise in any point of the cascade of hormone action.
