Oculopharyngeal myopathy with distal and cardiomyopathy.

Two patients are described with distinctive clinical features including an insidious onset, slow progression, bilateral ptosis, weakness of facial muscles, dysphagia, muscle atrophy, and weakness with a distal distribution in the extremities, and cardiomopathy with conduction system disorders. Electromyographic studies and muscle biopsy showed features highly suggestive of a myopathic disorder. One case is considered to be sporadic. The other seems to be a familial disorder, because of the presence of a mild atrioventricular block and right incomplete bundle branch block in the patient's son and the presence of eyelid ptosis in his sister. This may be a variant of oculopharyngeal myopathy with distal and cardiomyopathy. It will be necessary to perform long-term follow-up studies in these families.

A case of gamma heavy chain disease associated with autoimmune haemolytic anaemia: clinical, haematological, immunological and pathological details.

A 76-year-old Japanese man, presented with a case of gamma heavy chain disease associated with autoimmune haemolytic anaemia. The clinical course progressed rapidly, accompanied by fever, lymphadenopathy, erythematous palate and hepatosplenomegaly. As the disease progressed, haemoglobin level gradually reduced, and jaundice occurred. A complication of autoimmune haemolytic anaemia was deduced from the laboratory data obtained at this time. The patient's serum and urine contained an M-component with electrophoretic and antigenic properties resembling those of the Fc-fragment of G1 globulin. Microscopic and electron microscopic findings on the tumor cells infiltrating in lymphnodes indicated all types of transitional forms from small lymphocytes to large lymphoplasmoblastic cells.

Studies of sensory conductions. Comparison of latencies of orthodromic and antidromic sensory potentials.

Latencies of orthodromic and antidromic sensory potentials were compared in 16 normal median nerves. Peak latency was longer in the antidromic sensory response in every case. The peak latency of the antidromic sensory response depended on the distance between the recording electrodes; with shorter interelectrode distances it was similar to that of orthodromic sensory response.

Toxic polyneuropathy due to glue sniffing.

Four cases of toxic polyneuropathy due to glue-sniffing were reported. Neurological examination revealed motor predominant mixed type polyneuropathy. The cause of polyneuropathies in these cases was considered to be due to the inhalation of the vaporized elements of the adhesive agent, which contain mainly n-hexane and toluene. N-hexane is considered to be chiefly responsible for the polyneuropathy, though toluene also could have some influence on the illness.
