Journal of the Korean Radiological Society 1994;30(4):647-650
PURPOSE: To draw attention to the radiological findings of a benign variant of cerebral astrocytoma in a young patient. MATERIALS AND METHODS: A 24-year-old man with generalized tonic-clonic seizure of 7 years' duration and normal neurological examination was examined with plain skull series, brain CT and MRI, and cerebral angiography. MR imaging was performed with a 0.5 Tesla Toshiba MRT-50A scanner (TIWI, PDWI, T2WI, 0.1 mmol/kg of Gd- DTPA, SE). RESULTS: 1 ) Plain skull series: A radiolucent lesion with a partial radiopaque rim of about 2.5 x 3 cm size in the right anterior parietal bone.2) B rain CT scan: A cystic mass in the right frontoparietal cortex of midconvexity with pressure erosion on the adjacent skull and partial enhancement at outer and anterior portion.3) Brain MRI:A hypointense mass containing a small, intensely enhancing isointensity anterolaterally on Tl-weighted images, which was hyperintense with better delineation of bulging cortical-based appearance on T2-weithted images. No peritumoral edema.4) Cerebral anglography: An avascular mass. CONCLUSION: The diagnosis of pleomorphic xanthoastrocytoma(PXA) should be entertained in patients in whom a superticially placed enhancing intracerebral tumor containing cystic portion that seems to be in contact with the meninges develops during juvenile years.

Granulocytic sarcoma, a rare extramedullary solid tumor arising from early myeloid precursors, is capable of invading the meninges or the rain parenchyma. The tumor may occur during or after the onset of systemic myelogenous leukemia. On rare occasions, the tumor may evolve before the onset of systemic myelogenous leukemia. Children are affected more often than adults, but sex is not related. Although no definite target area of the brain can be demonstrated, there may be some predilection of the tumor for the posterior fossa. The authors report a case of 4-year-old-boy with granulocytic sarcoma occurring in the posterior fossa presenting with gait disturbance and torticollis. The patient was treated by surgical removal of the tumor, there by avoiding the potentially lethal complication of a posterior fassa mass. This rare case is reported together a review of the literature.

5.A Clinical Study of Calcipotriol Ointment in the Treatment of Psoriasis Vulgaris.
Korean Journal of Dermatology 1994;32(1):65-74
BACKGROUND: Calcipotriol, a new vitamin D3 analogue, is a potent growth inhibitor for human keratinocytes and has been shown to be effective in the topical treatment of psoriasis with no major disturbances of calcium homeostasis. OBJECTIVE: An open multicenter trial was conducted to assess the efficacy, safety, and tolerability of topical calcipotriol ointment(50ug/g) twice daily in the treatment of psoriasis vulgaris. METHODS: Op patients recruited from the Department of Dermatology of 30 universities and raining hospitals in Korea, 108 patients who could be followed up at the end of study were evaluated. Efficacy, as measured by the Psoriasis Area and Severity Index(PASI), and safety were assessed at 2, 4, and 6 week. RESULTS: Reduction of PASI score was stastically significant at all time points of treatment(p<0.01). At the completion of 6 weeks of treatment, the mean PASI reduction was 76.7%. The scores of thickness and scale decrease more than that of erythema. An analysis of patient and clinician overall self-assessment at 6 weeks showed cleared, marked improvement and moderate improvement in 65.2% and 62.9% at each. Some patients developed minimal irritation of lesional or perilesional skin. Laboratory tests did not show any significant changes particularly, serum calcium levels. CONCLUSION: Calcipotriol ointment was effective as measured by PASI score and the self-assessment in patients with psoriasis vulgaris and was well tolerated.

The associations between storm events, urban runoff and costal water quality have not been well investigated in Korea. A temporal and spatial analysis during summer, 2015 was conducted to determine associates between urban runoff and fecal indicator bacteria (Escherichia coli, Enterococcus) levels at two popular coastal beaches (Gwanganri beach and Haundae beach) in Busan. In this study, a clear relationship between rainfall and elevated number of indicators was observed. Two beaches met the costal beach water health standards after less than 3.0 mm of rain. Only for storms less than 2.5 mm was no observable rainfall effect. Our results revealed that exceedances were greatest in 5 hours following 41.0~45.5 rainfall, then declined the bacterial concentrations in 8 hours after the storm and they generally returned to levels below water health standards within 10~14 hours. But it took 2.7 days to get the level of water quality of dry days. The time required for water quality recovery depends on the intensity and duration of rainfall. In the event of intense rainfall issuance of beach closure by public authorities is warranted to protect public health.

BACKGROUNDTyphoid/paratyphoid fever (TPF) is endemic in Guizhou. We conducted wavelet analysis and Spearman's rank correlation analysis to explore the impact of meteorological variations on TPF infection in Guizhou, in an attempt to assess the risk factors associated with TPF epidemics.
METHODSWe examined the association between TPF incidence in Guizhou and temperature, precipitation and relative humidity using 24 years of data from 1984 to 2007. Periodicities of TPF incidence and the impact of climate factors on the TPF were detected by Spearman's rank correlation and wavelet analysis,
RESULTSTemperature and precipitation with a 1-month lag were positively correlated with the monthly incidence of TPF. The multiyear incidence pattern of TPF in Guizhou was explicitly periodic. Moreover, the association and driving effect of precipitation on TPF were observed, and the results showed that the incidence of TPF in Guizhou had a closer correlation with precipitation than with temperature.
CONCLUSIONSSafe water supply is the key issue for TPF control in Guizhou. Moreover, climate variation might impact the enteric infections, which may inform policy assessment for TPF control in Guizhou.
