[The diagnostic value of magnetic resonance imaging on neuromuscular diseases].

The article concentrated on the study of skeletal muscles of four extremities in 12 cases of different kinds of neuromuscular diseases and 4 volunteers with MRI. The results revealed: MRI could clearly display individual muscle, muscle groups or abnormal muscles morphologically. It could also demonstrate the difference between the neurogenic and myogenic changes. In patients with progressive muscular dystrophy (PMD), the gracilis m. and sartorius m. were relatively intact. In patients with primary myopathies, the severity of MRI changes was consistent with the severity of the illness and the EMG changes. The results indicated that MRI examination was helpful in the diagnosis of neuromuscular disorders. It can define the distribution and the severity of impaired muscles. In addition, MRI could be used to select the appropriate muscles for EMG examinations or muscle biopsies. Selective muscular impairments might be the characteristics of patients with PMD.

Cepholosporium acremonium. A new strain of fungus causing white piedra.

A strain of fungus (CZ408) was isolated from white piedra of a female child. Mycological identification showed that it is the first case in the world. Asymptomatic white nodules were noted on the hair of the scalp, and they were distributed irregularly along the shaft 4-10 cm from the scalp. The nodules, hard, not easily broken or removed, consist of hyphae, spores and metabolic materials around the hair. Oral antimycotic drugs are effective in treating this disease.

[Uremic neuropathy].

Two autopsy cases of uremic neuropathy were reported. The chief clinical features were progressive peripheral sensory impairment, especially of the deep sensation, and the distal weakness of the four extremities. Histopathological findings revealed not only marked segmental demyelination and axonal degeneration of the peripheral nerves, but also severe damage of the skeletal muscles, including the necrosis of the myofibers, streaming of the Z-band, aggregation of glycogen, and the presence of membranous bodies under the electron microscope. It indicated that both the peripheral nerves and the skeletal muscles were involved in some metabolic diseases.

[A 3 to 6-year follow-up study of 414 cases of cerebral infarction and cerebral hemorrhage].

To study the long-term prognosis, we performed annual follow-up examinations on 414 patients who had survived cerebrovascular accidents, including 334 cases of cerebral infarction and 80 cases of cerebral hemorrhage. All patients had been admitted to the Neurological Service of our hospital from January 1, 1976 to December 31, 1980, and were followed up for 3-6 years. The life-table method, the log rank test, and the rank sum test were used to determine the cumulative marked improvement rate, the cumulative recovery rate of pathological reflexes, the cumulative survival rate, and the cumulative recurrence rate. The results revealed the marked improvement rate in cerebral infarction was 81.98%, while in cerebral hemorrhage 89.87% at the end of 3 years after discharge. The recovery rate of pathological reflexes was 52.59% in cerebral infarction, 54.75% in cerebral hemorrhage at the end of 4 years. The cumulative survival rate was 58.67% in cerebral infarction, 53.36% in cerebral hemorrhage at the end of 6 years. The cumulative recurrence rate was 49.39% in cerebral infarction, 49.81% in cerebral hemorrhage at the end of 6 years.
