A Case of Anti-Hu Associated Paraneoplastic Subacute Sensory Neuronopathy

Subacute sensory neuronopathy usually occurs as a paraneoplastic syndrome, occurring most frequently in small cell lung cancer. We report a 63-year-old male presenting typical symptoms of subacute sensory neuronopathy. Electrophysiologic studies showed diffuse sensory axonal degeneration and anti-Hu antibody was positive in his serum. We reevaluated pulmonary lesions formerly diagnosed as active pulmonary tuberculosis. Chest computed tomography showed two nodules and hilar lymphadenopathy, and by percutaneous needle biopsy, small cell lung cancer was diag-nosed.

Histochemical Study of Muscle Fibers in Human Vertebral Muscle / 대한정형외과학회잡지

We evaluated the muscle fiber characteristics, the mean proportion of muscle fiber types and its range of individual difference in human vertebral muscle. Muscle samples used were from subjects who had a relatively brief history of spinal dysfunction such as compression fracture, disc hernia etc., and obtained from precisely defined superficial and deep sites on both sides of the vertebral column. In particular, samples were collected from three different levels of the column and flash-frozen sections of biopsied adult vertebral muscles were stained for H–E, trichrome, PAS, regular and reversed myosin ATPase, and SDH. Discrimination of muscle fiber types in H–E and trichrome stained sections was not evident. Three types of muscle fibers were, however, evident in PAS-stained sections according to the degree of positivity in observed vertebral muscles. The mean proportion of musele fiber types was different in regular and reversed myosin ATPase, and SDH stains and the majority of fiber types in human vertebral muscles was type I in three different levels of vertebral clumn. There was a decreasing tendency in percentage of type I fibers at both superficial and deep levels as the vertebral column descended. The size of muscle fibers was relatively larger in deep levels than in superficial levels of vertebral muscles. The human vertebral muscle showed moderately individual and regional differences in the mean size of fiber types. The evaluation for the combination patterns of various enzyme histochemical activities showed that the common musele fiber types(type I, II A and II B) were moderately reduced in the mean proportions and unusual rare muscle fiber types increased in number. And the decreasing tendency in the mean proportion of type as the vertebral column descended was not evident in the combination patterns of histochemical activities

Increase of Femoral Anteversion after Experimental Induction of Avascular Necrosis of Femoral Head / 대한정형외과학회잡지

An experimental study on the effect of the induced avascular necrosis of the femoral head on the femoral anteversion was made in the hips of 74 three to four-week-old rabbits. The results were as follows; l. In 18 of the 74 operated rabbits, a relative increase of anteversion was observed on the operated side, as compared with the nonoperated femur, the differences ranging from 10 to 75°(average increase was 25.9°). 2. Anteversion increase was actually internal rotation of femoral shaft starting from the subtrochanteric level and progressively increasing downward with spiral fashion. 3. The cause of anteversion increase was not proved in this experiment, but anteversion increase was a result of avascular necrosis.
