The reliability of emergency ultrasonographic(US) detection of hemoperitoneum and solid organ injury in blunt abdominal trauma was evaluated retrospectively. From October 1,1995 to August 31,1996,90 patients were included in the study. Ultra- sonographic findings showed a sensitivity, specificity, and accuracy of 97.6%, 97.9%, and 98.1%, respectively, in detecting intraabdominal fluid collection. We believe that US in an emergency center is a quick, safe screening method in the evaluation of blunt abdominal trauma. In our department, US has replaced diagnostic peritonaeal lavage(DPL) and computed tomography(CT) as the screening study of first choice.

Chronic postirradiation changes of skin reflect the injury of dermal structures particularly the vasculature and connective tissue. The clinical signs include atrophy, partial or complete destruc tion of cutaneous appendatges, telangiectasis, sclerosis of underlying tissue, pigrnentary changes, and in rare instances, ulceration with or without var ious premalignant and malignant neoplasms. The patient, was a 65-year-old man, who had been exposed to a large amount. of X-ray irradi- ation on his hands incidentally or accidentally for a long time. The skin changes of his hand were thickening and hardening of all digits loss or focal consttict,ion of digits, and keratotic papules. Epidermal hyperplasia and fibrous thickening of collagen bundles were found on skin biopsy. Gradual narrowingal of the bony caliber with eventual resorption was noticed on radiologic examination. It has been rarely reported in the literature that chronic radiation dermatitis develops severe and unusal manifestions such as acrosclerosis and loss of digit due to osteoradionecrosis.

The authors have presented 44 cases of chronic subdural hematoma which were diagnosed by brain computerized tomographic (CT) scan at the Department of Neurosugery, Keimyung University, School of Medicine from May 1980 to July 1982. There were 42 men and 2 women. The common incidence of age was between fourth and fifth decade. Most of the cases(80%) had a history of head injury and nearly all cases complained headache(93%). The most common sign was papilledema(71%) in relatively young age patients and mental change(62%) in old age patients. All cases performed brain CT scan, which showed hypodense(41%), isodense(21%), hyperdense(21%) and mixed dense(18%) lesion. The thickness of hematoma which was measured by brain CT scan revealed 10 mm-30mm in most cases and showed the tendency of increase in old age patients. Of 44 cases, 23 cases were treated with craniotomy and membranectomy, 18 cases with burr hole and drainage, and 3 cases which were bilateral lesion with both methods. There was not any different result in both methods and most of all cases showed good postoperative course except 3 cases of poor preoperative state.

PURPOSE: The spontaneous seroconversion rate of hepatitis B e antigen (HBeAg)-positive chronic hepatitis B (CHB) virus infection in children is lower than that in adults. However, few studies have investigated the rate of transition from the immune-tolerant to the early immune-clearance phase in children. METHODS: From February 2000 to August 2011, we enrolled 133 children aged <18 years who had visited the Department of Pediatrics, Kyungpook National University Hospital. All subjects were in the immune-tolerant phase of HBeAg-positive CHB virus infection. The estimated transition rate into the early immune-clearance phase was calculated using the Kaplan-Meier method. RESULTS: Among the 133 enrolled pediatric CHB virus infection patients in the HBeAg-positive immune-tolerant phase, only 21 children (15.8%) had converted to the early immune-clearance phase. The average age at entry into active hepatitis was 10.6+/-4.8 years. The incidence of transition from the immune-tolerant to the early immune-clearance phase in these children was 1.7 episodes/100 patient-years. When analyzed by age, the estimated transition rate was 4.6%, 7.1%, and 28.0% for patients aged <6, 6-12, >12 years, respectively. CONCLUSION: In children with CHB virus infection, the estimated rate of entry into the early immune-clearance phase was 28.0% for patients aged 12-18 years, which was significantly higher than that observed for children aged <12 years (11.7%; p=0.001).
