The emergency arteriography have been performed in a total of 13 patiens with extermity trauma, including 9fractures, 3 blunting traumas, and 1 penetrating injury. over 17 months period. The indications were as follows:absent or diminishe pulse, swelling, sensory or motor deficit , and hypotension. Patients with an absent pulse,the most reliable indication of arterial injury, should have immediate arteriography. The superficial femoralartery was commonly injured especially with distal femoral shaft fracture. The most common arteriographic findingswas arterial occlusion.

Few cases of ichthyosis bullosa of Siemens(IBS) have been reported since 1939, as a distinct entity from bullous congenital ichthyosiform erythroderma(BCIE). IBS can be differentiated from BCIE by the absence of congenital erythroderma and a different distribution of involved skin area. It's characteristic features include blistering, superficial erosion or moulting of the outer skin. Histological features are tonofilaments aggregation confined to the granular and upper spinous layer of the epidermis. However, in BCIE these findings are present in the whole suprabasal compartment. The original reports of Siemens and cases from other authors showed an autosomal dominant inheritance. Our patient developed IBS sporadically without a familial background.

PURPOSE: Pseudohypoparathyroidism(PHP) is caused by a defect of G protein and receptor despite of normal parathyroid hormone(PTH) secretion. It is a rare disorder characterized by hypocalcemia, hyperphophatemia, elevated PTH levels and albright hereditory osteodystrophy(AHO). We retrospectively reviewed the clinical characteristics of PHP. METHODS: We reviewed clinical features, laboratory findings, and outcome to treatment of 8 PHP patients, diagnosed at Seoul National University Hospital from 1988 to rool. RESULTS: Male to Female ratio was 1.7:1 and mean age at diagnosis was 11.8 years old. The initial average height SDS was 0.13+/-.08 and the average weight SDS was 0.43+/-.31. The most common symptom was seizure. Only one patient had typical AHO, three patients had mental retardation. Brain MRI or CT showed basal ganglia calcification in 3 patients. All patients treated with vitamin D and calcium supplementation could maintained normal serum levels of calcium and phophorus. CONCLUSION: PHP should be suspected in patient with seizure of unknown origin, aged above 5 year-old. AHO and mental retardation could be adjuvant signs to the diagnosis of PHP. But definite diagnosis could be made by laboratory work up.

BACKGROUND: It is well known that ischemic preconditioning protects the heart against infarction or arrhythmias from a subsequent ischemic injury. Recent laboratory data indicate that the adenosine during the ischemic period may trigger protection via A1 or A3 adenosine receptor and also protein kinase C(PKC) plays a central role. This study was designed to determine the role of adenosine receptor subtypes and PKC in the preconditioning protection. METHODS: All cat heart groups were subjected to 40min ischemia and 30min reperfusion. The preconditioning protocol consists of 4min ischemia and then 10min of reperfusion 4 times. The effects of ischemic preconditioning, nonselective adenosine receptor blocker(SPT), an A1 specific antagonist(DPCPX) and protein kinase C inhibitor(Polymyxin B), on ischemic preconditioning were determined by infarction size. There were 5 groups : (1) control group (Group 1, n=10)(2) Ischemic preconditioned group(Group 2, n=9)(3) DPCPX pretreatment group(Group 3, n=6)(4) SPT preteatment group(Group 3, n=6)(5) Polymyxin B pretreatment group(Group 5, n=6). SPT and DPCPX were given intravenously 5 min before ischemic preconditioning. Polymyxin B was administered to cats for 30min during ischemic preconditioning period. RESULTS: Ischemic preconditioning only or pretreatment with DPCPX prior to preconditioning demonstrated a significant reduction in infarct size(22.6+/-1.5, 25.4+/-0.9% infarction of the risk zone, respectively, p<0.05) with respect to control, SPT-pretreatment, and polymyxin B-pretreatment groups(44.0+/-1.7, 43.0+/-2.0 and 40.3+/-0.4% infarction of the risk zone, respectively). CONCLUSIONS: Ischemic preconditioning protects heart from subsequent ischemia. Protection was blocked by SPT and protein kinase C inhibitor(polymyxin B), but not by A1 antagonist DPCPX. The cardioprotective effects by ischemic preconditioning in the in vivo cat heart appear to be dependent on A3 adenosine receptors and activation of protein kinase C.

PURPOSE: MR findings of the spinal metastasis and the tuberculosis are well known, but sometimes it might be difficult to differentiate these lesions. Therefore we reviewed and analyzed the MR findings which would be useful for the differentiation. MATERIALS AND METHODS: T1- and T2-weighted spin echo images and gadolinium-enhanced Tl-weighted images were obtained with 1. 5T and 1. 0T superconductive MR imager. We reviewed MR findings in 16 cases of spinal metastases and 24 cases of spinal tuberculosis in terms of signal intensity, contrast enhancement pattern, disc space involvement, spinal canal compressing feature and paraspinal soft tissue mass. RESULTS: The signal intensities of both lesions were hypointense on T1WI and hyperintense on T2WI except those of the metastatic lesions from the prostatic carcinoma. Heterogeneous enhancement was noted in 63% of metastasis, whereas peripheral rim enhancement was noted in 83% of spinal tuberculosis(p (.001). Spinal canal compression by collapsed vertebra was only noted in spinal metastasis, and that by paraspinal soft tissue was noted in both spinal metastasis and tuberculosis(p (.001). Disc space invasion was noted in 19% of spinal metastasis and 88% of spinal tuberculosis. Spinal tuberculosis was common at lower thoracic spine(T10) and typically involved two or more adjacent vertebral bodies(96%). CONCLUSION: The important differential point between spinal metastasis and tuberculosis was the enhancement pattern, involvement of two or more contiguous vertebral bodies and the feature of spinal canal compressing. The secondary importance was the disc space involvement pattern.

BACKGROUND: In spite of the development of diagnostic tools, gallbladder carcinoma is often diagnosed at a late stage because of the lack of symptomatic awareness of patients in early stage. Early diagnosis and proper resectional treatment is, therefore, the most important factor for the prognosis. This study aims at the analysis of clinical characteristics and the effect of various modes of surgical treatment on long-term survival. METHODS: From January 1989 to December 1997 we operated on 132 patients with gallbladder carcinoma. Age, sex, stage distribution, clinical manifestations and mode of operations were analyzed. The cumulative survival rates were also analyzed for 107 patients who had been finally followed up, and the significance of survival difference was tested (p<0.05). RESULTS: The average age of 132 patients was 64 years old, and female patients suffered more frequent incidence than male patients by a ratio of 1.7:1. The distribution of patients according to the pathologic TNM staging showed early stage (stage 0 & I) accounted for only 9.8% whereas the advanced stages (stage II, III, IVa, IVb) accounted for the majority of the patients (90.2%). The chief complaints were abdominal pain (84.8%), indigestion, weight loss, palpable mass and so forth in a decreasing frequency order. Among the patients, 30 cases (22.7%) were irresectable, 50 cases (38%) were curative resected, and 52 cases (39%) were palliative resected. The overall cumulative survival rates of 107 patients were 53.7%, 41.7% and 30.1% for 1-year, 2-year and 5-year survival respectively. Although the 5-year survival rate of curative resected patients showed a significantly better survival rate (p<0.005) than that of non-curative resected patients, the different modes of combined radical surgery did not affect the survival rates. CONCLUSION: Combined curative resection ameliorated long-term survival of patients with gallbladder carcinoma. For the further evaluation of the efficacy of combined radical surgery on survival, more extensive data needs to be accumulated.

PURPOSE: Ingested foreign bodies present a common clinical problem. It is well known that most of them pass uninterrupted through the gastrointestinal tract. We evaluated the role of endoscopy and Foley catheter for removal of foreign bodies in the gastrointestinal tract. METHODS: We investigated retrospectively 60 cases with foreign bodies in the gastrointestinal tract. They had been treated at Wonju Christian Hospital, Yonsei University of Korea, from January, 1996 through December, 1999. RESULTS: The age of the patients ranged from 7 months to 13 years. Patients under 5 years were 57 cases (97%) and there was no significant difference in sex (M : F=1.07 : 1). 45 cases of the patients had no symptom. The most common foreign bodies were coins (43 cases). The most common location was esophagus (31 cases). The number of foreign body removal using flexible endoscopy and Foley catheter was 22 (36.7%) and 18 (30.0%) cases, respectively. In 18 cases (30.0%), foreign bodies passed spontaneously. Only 1 case (1.7%), curtain pin impaction at ileocecal region, required surgery. CONCLUSION: Early foreign body removal from esophagus and stomach is recommended to lessen the morbidity and complication. Fluoroscopic foley catheter technique and flexible endoscopy for removal of esophageal foreign bodies in children is safe and effective.
