[Peripheral neuropathy due to N-hexane in a drug addict (author's transl)].

After voluntary inhalation of a domestic solvent containing N-Hexane and N-Heptane for three months, a 23-year-old woman developed motor deficit of the lower limbs, sensory symptoms and areflexia. Clinical disorders continued to progress after discontinuation of the intoxication, with a parallel aggravation of the E.M.G. disturbances. A nerve biopsy with ultrastructural study showed axon dilatation with accumulation of neurofilaments. The clinical, electrophysiological and pathological features of neuropathies induced by hexacarbon solvents are reviewed and their pathogenesis is discussed.

[Genetic deficiency of thyroxin-binding protein in 4 members of a family (author's transl)].

Four members of the same family (2 male and 2 female) with normal thyroid function were found to have decreased total T3 and total T4, elevated response to the T3 test and low free thyroxin index. Such biological changes result from a deficiency in carrier protein and should be distinguished from nearly similar abnormalities observed in low T3 syndrome and hypothyroidism. Whilst gonosomal transmission through the X chromosome of thyroxin-binding protein deficiency seems well established, our findings show that another mechanism, i.e. dominant autosomal heredity, is practically certain.

[Chronic hepatitis in sex linked agammaglobulinemia. One case (author's transl)].

The authors report the case of a 21 years old man, with sex-linked agammaglobulinemia, who presents a presumed viral hepatitis, followed two years. The evolution, does yet fear a progressive cirrhosis. About this report and analysis of literature, frequency, evolution and pathophysiologic hypothesis, particularly the lymphocyte T role, are also discussed as the problem of hepatitis prevention of these subjects, who receive gammaglobulin injections.
