Clonorchiasis is known to be closely related with the development of recurrent pyogenic cholangitis and carcinoma of the bile ducts. In order to ascertain the cholangiographic signs for recurrent pyogenic cholangitis or carcinoma of the bile ducts arising in patients with clonorchiasis. we reviewed cholangiograms in 42 patients with proven clonorchiasis. The population consisted of 29 patients with clonorchiasis alone, six patients with clonorchiasis and recurrent pyogenic cholangitis, and seven patients with clonorchiasis and carcinoma of the bile ducts. Cholangiographic abnormalities in 29 patients with clonorchiasis alone, six patients with clonorchiasis and recurrent pyogenic cholangitis, and seven patients with clonorchiasis and carcinoma of the bile ducts. Cholangiographic abnormalities in 29 patients with clonorchiasis alone were intrahepatic multiple, oval, or elliptic filling defects measuring 2-10 mm in size, representing adult flukes (n=24). The peripheral bile duct were obstructed (n=18), and the margins were ragged (n=20) and hazy (n=12) the intrahepatic bile ducts were dilated diffusely (n=27), and the dilated peripheral small tributaries gave the impression of "too many ducts appearance" (n=7) and dilatation was mid (n=17) In six patients with clonorchiasis and recurrent pyogenic cholangitis, there were filling defects of stones, and the extrahepatic ducts and larger intrahepatic ducts were predominantly dilated. In seven patients with clonorchiasis and cholangiocarcinoma all the biliary tree proximal to the tumor was markedly and diffusely dilated In the latter two groups, filling defects of flukes and associated findings were less prominent, but there was disproportionately severe dilatation of too many intrahepatic ducts. In patients with recurrent pyogenic cholangitis or cholangiocarcinoma, clonorchiasis should be considered as a underlying cause when cholangiogram shows "disproportionately" severe dilatation of too many intrahepatic ducts. intrahepatic ducts.

Although there has been recently noted a nation-wide spread of Trichophyton verrucosum infection in cattle associated with promoted stock raising and dairy farming, there were no case reports in Korean dermatologic literature describing the characteristic clinical features of tinea barbae caused by that particular fungus. We report 3 cases of tinea barbae due to T. verrucosum that developed in male stock farmers breeding cattle. One Patient acted 37, experienced acutely inflamed bo99y tumors on the chin and sub-mandible. The others aged 43 and 46 experienced inflammatory lesions with multiple follicular pustules, crusts and loss of hairs on their upper lips. They were successfully treated with oral griseofulvin and local antifungal ointment combined with short-term oral antibiotics or corticosteroid for about one month.

Purpose: The coronavirus disease 2019 (COVID-19) pandemic has significantly disrupted cancer screening services worldwide. We aimed to measure the impact of COVID-19 on gastric cancer screening rates based on age, sex, household income, and residential area. Materials and Methods: We analyzed data from the Korean National Cancer Screening Survey from 2017 to 2021 for adults aged 40–74 years. We evaluated the gastric cancer screening rate within two years in accordance with the National Cancer Screening Program protocol recommendations and that within the previous year. We compared the trends in the pre- and post-COVID-19 outbreak periods. Results: Before the COVID-19 outbreak, there was little change in the gastric cancer screening rates until 2019. After the COVID-19 outbreak, the screening rate as per recommendation decreased from 70.8% in 2019 to 68.9% in 2020 and that for one year decreased from 32.7% in 2019 to 27.2% in 2020. However, as the COVID-19 pandemic continued after 2020, both gastric cancer screening rates as per recommendations and for one year rebounded. Although a similar trend was observed for the upper endoscopy screening rate, the upper gastrointestinal series screening rate decreased from 7.8% in 2020 to 3.1% in 2021. During the pandemic, the screening rate decreased among younger adults (40–49), those residing in metropolitan regions, and those with high incomes. Conclusions Despite a decline in gastric cancer screening rate during the COVID-19 pandemic, the rate surged in 2021. Further studies are needed to estimate the impact of cancer screening delays on future cancer-related mortalities.

The residual tense false lumen following surgical repair of aortic dissection remains one of the most difficult and challenging postsurgical problems. Percutaneous fenestration of the dissecting membrane under the guidance of intravascular ultrasound has been recently introduced to depressurize the tense false lumen. A 63-year-old woman who underwent repair of acute type I dissection was readmitted because of claudication and numbness of the left lower extremity. Angiography, computed tomography, and magnetic resonance imaging clearly showed a dissection flap starting from the thoracic aorta distal to the left subclavian artery. Compressed true lumen by the markedly enlarged tense false lumen was also noted in the double-channeled descending thoracoabdominal aorta. Under intravascular ultrasound guidance, the intimal flap was punctured with a Brockenbrough needle advanced to the true lumen through a femoral artery, and then, a balloon catheter was introduced over the guidewire which was placed across the dissection flap. Desired fenestration was obtained successfully by inflation of the balloon without complications. After procedure, symptoms resolved promptly and she is currently(clinical follow-up of 12 months postfenestration) ambulating without claudication. In conclusion, percutaneous fenestration of the intimal flap is a technically feasible and an effective alternative procedure to surgical repair for restoration of perfusion to an ischemic extremity in selected patients complicated with aortic dissection.

PURPOSE: To investigate the nature of edematous lesions seen on MR images during acute episodes of hypertensive encephalopathy(HTE) with particular attention to the findings of diffusion-weighted imaging (DWI). MATERIALS AND METHODS: A total of 17 MR examinations in fourteen patients with hypertensive encephalopathy were performed. The diagnoses were idiopathic HTE in eight cases, eclampsia in three, and cyclosporin-induced HTE in three. The apparent diffusion coefficients(ADCs) of edematous lesions and normal white matter revealed by DWI were assessed and compared, and the changes observed at follow-up MR imaging were analysed. RESULTS: DWI obtained within one week of the appearance of acute neurological symptoms revealed the edema as iso-intense in all patients with eclampsia and cyclosporin-induced HTE, and in five of eight patients with idiopathic HTE. In the other three patients with idiopathic HTE, DWI demonstrated slightly hyperintense edema. The ADCs of edematous lesion in patients with idiopathic HTE, eclampsia and cyclosporin-induced HTE were 1.21 +/-0.34, 1.08 +/-0.28, and 1.28 +/-0.22 mm 2 /ms, respectively, while for normal white matter the corresponding figures were 0.77 +/-0.25, 0.71 +/-0.22, and 0.68 +/-0.27mm 2 /ms The differences in ADCs between edema and normal white matter were thus significantly different between the three patient groups (p<0.05), while the ADCs of edematous lesions showed no sisgnificant variation between these groups (p<0.05). Follow-up MRI revealed that in three cases, edematous lesions were reversible and there were no residual signal changes. CONCLUSION: Vasogenic rather than cytotoxic edema is present during the acute stage of HTE.

Spinal hemangioma is the uncommon, slowly growing benign tumor that arises from the blood vessels and commonly located in thoracic spine. We have recently experienced a caseof capillary Hemangioma in intradural extramedullary space of thoracic spine level. The patient presented with a slowly progressive weakness of both lower extremities and hypesthesia below T6 dermatome. The plain X-ray films, thoracic spine myelography and CT scan disclosed an intradural mass at T5 level. The mass was surgically removed and conformed by histological examination.

OBJECTIVE: Primary intraventricular hemorrhage(PIVH) is uncommon and accounts for only 3.1 % of all non-traumatic intracerebral hemorrhage. The aim of this study is to analyze clinical characteristics, image features, etiology and prognostic factors of outcome in patients with PIVH. METHODS: We identified 25 patients with PIVH during 9-year period between 1994 and 2002 at our institute. The clinical data, complimentary examination, outcome and computed tomographic blood amounts were reviewed. RESULTS: Major symptoms included sudden decreased level of consciousness, headache, nausea/vomiting and neck stiffness. Cerebral angiography was performed in 12 patients(48%) and revealed vascular malformation in 6 patients(24%). The positive result of angiography was more common in young patients and among vascular malformation the incidence of Moyamoya disease was relatively high(4 patients). Other causative factors were coagulation disorder, arterial hypertension, tumor bleeding. Outcome were death in 9 patients(36%): 7 patients(28%) died by direct consequence of bleeding and 2 patients died after other adverse events(sepsis, hepatic failure) but prognosis of survivor was good. Factors correlating with the outcome were the presence of coagulopathy, initial Glasgow Coma Scale(GCS), obstruction of 4th ventricle and ventricular blood amount including hemorrhagic dilatation of temporal horn of lateral ventricle, 3rd and 4th ventricle. CONCLUSION: The poor prognosis factors of PIVH are the presence of coagulopathy, low initial GCS, obstruction of 4th ventricle and large ventricular blood amount. Additionally patients whose initial clinical condition is not serious need an appropriate work up including cerebral angiography, because cause of bleeding is vascular malformation especially in young patients.
