[Clinical picture and pathogenesis of the Refsum syndrome].

The author reports of 2 cases (sisters of 13 and 15 years old) with the Refsum syndrome. The disease had its onset at the age of 12 and 5 years with a progressive development and remissions. The clinical picture was characterized by a recurrent syndrome of polyradiculoneurites with a slight protein cellular dissociation in the CSF, an expressed sensitive ataxia with elements of cerebellar disorders, a drop in the acuity of sight, audition, intellectual level and a deformation of the talipes of the Friedreich type. In a single examination of fatty acids in the blood serum by the method of gas chromotography there were no data pointing to the existence of 3, 7, 11, 15-tetra metylhexadecone acids. On the basis of an immunological study the author discusses the role of autoimmune reactions in the pathogenesis of the diseases. A differential diagnosis was conducted between acanthocytosis and porphyria with recommendations in regard to treatment.

[McArdle's disease (a familial case)].

The author describes a family (48 year old mother and 15 year old son) with the muscular variant of glycogenosis-McArde's metabolic myopathy. The mother has been ill since 22 years old, the son--since 7. The disease had a slowly progressive development. The clinical picture was characterized by convulsions of the type of cramps following physical loadings on muscles of the body and extremities. Convulsions were accompanied by pain, an induration and enlargment of the muscles, muscle fatigue and increased significantly in an artifical ischemia of the extremities. A histochemical study of the muscle revealed a pathological accumulation of glycogen. The content of lactic and pyruvic acid in the blood after work in ischemic conditions did not change significantly. A study of the sugar curve in the blood with a loading with glucose and a parallel determination of insulin by a radioimmune method found hyperinsulinemia and a dysfunction of the pancreas.
