To our knowledge, MR findings of neuroshistosomiasis has not been reported in Korea. A case of neuroshistosomiasis involving cerebellum and presumably spinal cord is reported. A 40 year old man who had lived in Middle East complained of low back pain and progressive paraparesis for 6 months, and subsequently developed headache, dizziness and diplopia. On cervical spine MRI, there was diffuse enlargement of cervical cord with increased signal intensity on T2 weighted image and nodular heterogenous enhancement after Gd-DTP^ administration. Brain MR imaging obtained 4 months later showed ill-defined, irregularly enhancing heterogenous mass in cerebellar vermis which was proved to be a granulomatous lesion containing shistosomiasis mansoni ova.

Congenital lipoid adrenal hyperplasia, the most severe form of congenital adrenal hyperplasia, is caused by mutations in the steroidogenic acute regulatory protien (StAR). It is characterized by failure of synthesis of all three classes of adrenal steroids and massive accumulation of lipids and cholesterol in the adrenal cortex. The computed tomography (CT) unequivocally delineated massively enlarged adrenal glands of fat-tissue attenuation, enabling early diagnosis and replacement therapy. We report a case of congenital lipoid adrenal hyperplasia, in which CT established that lipoid deposition at the adrenal cortex disappeared after the adrenal hormone replacement therapy.

A pair of eyes of a 18 year-old girl with advanced congenital glaucoma was examined by light and electron microscopy. Results were as follows: 1. Trabecular meshwork and iris root showed fibrosis. 2. Schlemm's canal was absent. 3. Endothelium of the trabecular meshwork was degenerated. 4. Ciliary body was atrophied. 5. Inner layer of retina showed degeneration with the loss of nerve fiber layer and ganglion cell layer, which was replaced by Mueller cells. 6. Optic nerve showed atrophy from a loss of nerve fibers and there was proli feration of collagen tissue.

A study of effect of local hypothermia upon the spinal cord was performed in cats. With a cuff, a cooler, to which was attached connecting tubes to a refrigerator, the experimental technique was deviced to cool the spinal cord locally at midthoracic level. Cold liquid, saline at a temperature of +/-1.1 degrees C, was circulated in closed system through the tubing into the cuff which was snugly rested on the dorsal surface of the spinal cord as a heat exchanger. The temperatures were measured with thermocouples at various sites in the spinal cord before, during, and after the cooling every two minutes upto twenty minutes. In the cord underneath the cuff, the mean precooling temperature of 35.4 degrees C in normal control group was lowered to 11.0 degrees C during the first two minutes of cooling. After this in initial rapid drop in temperature, there was a further gradual reduction of 4.5 degrees C upto 20 minutes cooling to be 6.5 degrees C. The lowest mean temperatures recorded throughout cooling were 4.3 degrees C at dorsal surface and 6.9 degrees C at center of the cord. And the temperature lowering was nearly not noted beyond the cord 1 cm apart from an edge of cuff in rostral and caudal directions. For comparison, the temperature in the cord that had not been injured was also measured. The rate of cooling in the cord underneath the cuff seemed to be faster than in the control group of animal in which the cord was not injured. Another design of this experiment was an evaluation of the protective effect of local hypothermia with respect to cord edema and injury associated cord hemorrhage. Immediately after intravenous administrations of fluorescin the spinal cords were contused with impaction injury. These injured cords were removed ar different time intervals after trauma, and spread or distribution of fluorescin in frozen sectioned specimens was observed under ultraviolet illumination with fluorescence microscope. In all cooling groups, pathological pictures were reduced in its degree and extent more than those in the control group, and that, earlier the cooling after the injury to the cord, better the result was outcome. It would be well to say that local hypothermia might be within the margin of safety and beneficial in the management of spinal cord injury in this experiment.

BACKGROUND: Many non-invasive, continuous-monitoring blood culture systems have introduced technology that reduces the time and labor. There is a report that terminal subculture is necessary to decrease false negative. The purpose of this study is to evaluate the terminal subcultures for blood cultures monitored by VITAL system and to determine the clinical significance of positive blood cultures not detected by VITAL system. METHODS: From June to August 1996, a total of 3,988 blood culture bottles were processed by VITAL system and terminal subcultures were performed on consecutive 5 day blood culture. Any culture that was instrument positive but negative upon terminal subculture was considered to be false positive. Any culture that was instrument negative but positive upon terminal subculture was considered to be false negative. And false negative were categorized into minor and major errors. RESULTS: Two-hundred and nineteen (5.5%) out of 3,988 blood culture bottles were signaled as positive by VITAL system. Twenty-four bottles out of 219 were VITAL positive but negative upon terminal subcultures (false positive rate, 0.8%). And seven of the 3,988 terminal subcultures were false negative (0.2%). Four out of seven were major error and three were minor error. The isolates of major error bottles were Staphylococcus spp. and minor error bottles were Escherichia coli and Candida tropicalis. These isolates were clinically significant pathogens, but there were no changes on antimicrobial chemotherapy after reporting the positive blood culture reports. CONCLUSIONS: These results suggest that using VITAL system, terminal subculture of 5 day instrument-negative blood culture bottles is not necessary and the VITAL system provides for the rapid and convenient tool for detecting bacteremia.
