PURPOSE: Venous thromboembolism (VTE) is a common life-threatening illness with significant morbidity and mortality rates. In recent years, the incidence of VTE has gradually increased in Korea. In this study, we evaluated the current trends in the management of acute deep vein thrombosis (DVT) in Korea. MATERIALS AND METHODS: A 20-item questionnaire was prepared and sent to 48 members of the Korean Society for Vascular Surgery. Each member worked in a different hospital. Twenty-two members participated in this study. RESULTS: The vascular surgery departments were primarily responsible for managing DVT. Ultrasound and computed tomography (CT) venography were chosen as the most common initial diagnostic tools. Eighty-two percent of participants routinely used the coagulation factor assay. Thrombolysis and inferior vena cava (IVC) filter insertion were performed mainly in the radiology departments. Seventy-seven percent of participants performed thrombolysis only if the thrombus age was less than 21 days. During thrombolysis, IVC filter was routinely inserted by 50% of respondents and removed within 14 days by 64% of respondents. Nearly all participants followed the 2012 American College of Chest Physicians guidelines for anticoagulation therapy. CONCLUSION: The majority of Korean vascular surgeons followed the guidelines. However, CT was frequently used. Thrombolysis and IVC filter insertion were more frequently performed than recommended by the guidelines.

In 1978, Bjornberg and Friis reported 32 patients with persistent pusi ulosis(PP) on distal extremities, of whom 13 patients were initially diagnosed as scabies. In 1984, Elpern described 7 patients with infantile acropustulosis(IA), of whom 4 patients had antecedant scabies. We report herein a case of PP, which was found in a 18 month-old mal who was treated for scabies at the age of 5 month and 12 month. The pruritic vesicopustules dev',lo ed 2 months after the second treatment for scabies and relapsed for 4 months. We also discuss the relationship between scabies and PP and also between PP and IA.

A 37-year-old female presented with a lobulated 2.5 x 1.5cm sized tumor with several sat ellite papules on the left lateral malleolar area for 27 years. Hiopsy specimens from hoth the lobulated lesion and the satellite lesion showed findings similar with features of intradermal nevus.

OBJECTIVE: To investigate the conduction velocity of sympathetic skin response(SSR) in normal adults. METHOD: The latency of SSR was measured in 41 normal healthy subjects by the simultaneous recordings from three sites of the hand. And we also measured the distance and conduction time between the recording sites of the hand. The conduction velocity of SSR was calculated by dividing the distance by conduction time. RESULTS: The SSR was obtainable in all subjects from three sites of the hand. The mean latencies of SSR recorded from wrist, midpalm and index finger were 1.29, 1.40 and 1.54 seconds respectively. And the mean latency showed a significant increase from wrist to index finger(p<0.05). The conduction velocity of the SSR from wrist to index was 0.57 m/sec, and segmental conduction velocities from wrist to palm and palm to index were 0.62 and 0.66 m/sec respectively. The conduction velocity of SSR in the distal segment was slightly faster than in the proximal segment with no statistical significance. CONCLUSION: The conduction velocity of SSR by the simultaneous recordings at two or more sites of the hand can be easily obtained and offers a useful parameter along with the amplitude and latency of SSR.

The congenital absence of the extensor indicis proprius tendon was never reported but authors experienced one case of bilateral absence of the extensor indicis proprius tendon and treated by transfer of the extensor digiti quinti with good result.

Hydrofluoric acid is one of the strongest irritating, corrosive and poisonous inorganic chemicals. The most significant chronic consequence of excessive fluoride exposure is the disorder of skeletal system and connective tissue. The first stage of osteofluorosis consists of an increase in the density of flatbone such as pelvic bone and vertebral bones, with coarseness and blurring of bone trabecular. Therefore we wanted to observe the change of the bone density among workers exposed to hydrofluoric acid. Questionnaires and radiological investigations were performed for 39 hydrofluoric acid manufacturing factory worker sexposed to hydrofluoric acid. And then authors checked urinary fluoride level by fluoride ion method. the radiographs were doubly read by two radiologists for reliability. The results were as follows; 1. There was a significant difference in urinary fluoride level (p<0.01), but not in age, in tenure(p>0.05) among workers by the job title. 2. By the two radiologists, eight cases were read as bone fluorosis. The prevalence rate of bone fluorosis was 20.5%. 3. There was not a significant difference in general characteristic such as age, tenure and in muculoskeletal signs and symptoms between the fluorosis group and the normal group. 4. However, a close relationship between the occurence of the change of bone density and the degree of fluorde exposure such as burn was found. The difficulties in diagnosing fluorosis result from the questionable sensitively of x-ray techniques and from the non-specific associated signs and symptoms. A quantitative method such as densitometry to assessosteosclerosis and bone structure alteration and a follow-up study are needed.

PURPOSE: To evaluate the major radiologic features of chronic focal pancreatitis in various imaging studies, with special emphasis on CT and ERCP findings. MATERIALS AND METHODS: From 1991 to 1995, twelve patients were pathologically proved to be suffering from focal chronic pancreatitis after pancreatico-duodenectomy ; for retrospective evaluation, imaging studies were available for eight(seven men, one woman ; mean age 58.9+/-6.6, range 47 to 67). Clinical, surgical, and radiological findings, including CT(n=8), ultrasound(n=7), ERCP(n=8) andUGI(n=3) were analysed. RESULTS: Seven male patients had suffered from chronic alcoholism for between 20 and 50years. Serum bilirubin levels were normal in eight patients and alkaline phosphatase levels were normal in seven patients. Serum CA 19-9 levels were normal in all five patients who had undergone preoperative evaluation. Seven patients(87.5%) showed focal enlargement without definable margin on CT, and five of the six lesions detectable on ultrasound(83.3%) were ill defined hypoechoic nodules. Dilated side branches within lesions were seen in five ofeight patients(83.3%) on CT and ERCP. Double duct signs were observed in siven(87.5%) patients, and dilated intrahepatic ducts in six(75%), with diameters ranging from 5 to 8mm(average : 5.42+/-1.96mm). The average ratio ofpancreatic duct caliber to gland width was 0.33+/-0.19. None of the patients had calcification within the lesionand one case showed intraductal calcification. None showed perivascular fat obliteration around the superiormesenteric artery or celiac axis. The average biductal distance between abnormal common bile duct and theimmediately adjacent pancreatic duct was 4.0+/-1.15mm. One of three cases who under went a UGI examination showed severe luminal narrowing and mucosal thickening in the second portion of the duodenum, another showed double contour, and the other merely showed widening of the C-loop of the duodenum. CONCLUSION: Chronic focalpancreatitis mostly demonstrated ill defined focal enlargement and double ductal dilatation. Dilated side brancheswithin the lesion, no vascular encasement, a mild degree of intrahepatic ductal dilatation, a ratio of pancreatic duct to parenchymal width of less than 0.5, and clinical findings including chronic alcoholism and normal CA 19-9serum level may be reliable indicators for differentiating chronic focal pancreatitis from pancreatic cancer.
