PURPOSE: To identify the four layers based on intranodular vascular nature visible in multiphase incremental bolus dynamic CT and to determine any differential points according to various factors of liver abscess with this vascular nature or not. MATERIALS AND METHODS: We categonized 29 cases of confirmed liver abscess into three different groups according to presence of four layers visible in early phase(arterial phase) of CT. Three groups were compared in regard to the results of antiamebic antibody test and bacteriologic study and presense of cholangitic abscess and internal septation. RESULTS: We could separate four layers, innermost hypodense central cavitary lesion, hyperdense granular tissue, hypodense abscess wall and outermost hyperdense compensatory hypervascular zone in 18 cases(62%), only two layers, cavity and wall in six cases(21%), and characteristically we could find three layers without innermost cavitary lesion in five cases(17%). But we couldn't find significant correlations between various clinical factors of liver abscess and our vascular groups. CONCLUSION: Our method of CT could represent four layers based on vascularity in 62% of cases. And also could find the unusual inflammatory mass containing three layer which must be differentiated from other malignant solid mass. But we couldn't find differential point between various clinical factor of liver abscess and imaging diagnosis. We think that with the improvement of hardware such as spiral CT, identification of four layers will be earier and will be very helpful in early detection and proper treatment planning of liver abscess.

A 12-year-old girl presented with a 1-week duration of hair loss associated with splitting of the hair ends and whitish dots on the occipital hairs. On microscopic examination, a longitudinal splitting of the hair shaft with reconstitution of the normal hair distal to the fracture, nodular swellings, with the appearance of broomsticks pushed into one another, at the site of whitish swellings, and the flattening and twisting of the hair shaft around the long axis were demonstrated. Minor trauma to injury-prone hair is a common cause of hair shaft defects, however the reports with the combined conditions are insufficient in the literature. We describe a patient with central trichoptilosis associated with localized trichorrhexis nodosa and pili torti.

Chronic subdural hematoma usually occurs as a consequence of minor trauma. But, chronic subdural hematoma of occupational origin has not been reported yet in Korea. We experienced a case of chronic subdural hematoma induced by repeated trauma to the head. The patient was a 45-year-old male. He complained of repeated headache and nausea. By the computed tomogram, he diagnosed as chronic subdural hematoma and took the operation. He was not an alcoholism and had no intracranial disease nor coagulopathy. We studied all possibilities through working environment and personal environment survey. As a result, we decided the case as an example of cumulative trauma disorder to the head by occupational origin. We report a case of chronic subdural hematoma in the worker exposed repeated head trauma of occupational origin.

From January 1995 to December 1997, a total of 219 cases pelviscopic surgery was performed at Il Sin Christian Hospital. To evaluate the safty and efficacy of pelviscopic surgery, we reviewed indication of operation, mean age, parity, history of abdominal operation, type of operation, duration of hospitalization and complication retrospectively. The number of pelviscopic surgery have risen from 33 cases in 1995 to 53 cases in 1996 and 133 cases in 1997. The most common indications were 118 cases for ectopic pregnancy (53.9%) and 42 cases for ovarian cyst (19.2%), 20 cases for infertility (9.1%) in order. Among the ovarian cyst, endometrioma was the most common. The mean age of patients was 31+/-6.7 years old and mean parity was 0.77. In most cases, mean blood loss was lesser than 100 cc except 500 cc in LAVH, 150 cc in CISH, 106.7 cc in ectopic mass removal. The postoperative hospital stay was varied from 0 day to 10 days, but usually 2 days. The 26 cases had complicated and the most common complication was fever above 38degrees C. In conclusion, it is evident that pelviscopic surgery is lesser invasive technique, has lower complication rate and shorter the length of hospitalization. So, we expect the number and indication of pelviscopic surgery will be increased in future.

Nine-month-old female infant was seen with a 7-month history of a nodule on the right temporal scalp, which had gradually increased in size. Stroking of the lesion resulted in urtication and blistering and there were no other cutaneous lesions. The histology showed subepidermal bulla formation and a dense infiltration of mast cells in the papillary and reticular dermis. We present an infant with solitary mastocytoma on the scalp, a rare site.

Twenty-one patients of the adult Japanese encephalitis, who had been admitted in National Medical Center during recent two years, were investigated to evaluate their epidemiological features and clinical courses. Male patients were more frequently affected than female, and forty-three percepts of patients were third decade. The peripheral leukocytosis and mild pleocytosis and non specific inflammatory findings in cerebrospinal fluid were observed, all case had positive titer in hemoagglutination inhibition test. The incidence of neuropsychiatric sequelas of Japanese encephaltis was about 67%, and among them speech disturbance was most frequent. Further epidemiological and microbiological studies should be necessary to evaluate the tendency of recent increment in incidence of adult type of Japanese encephalitis.

Craniofacial clefts are rare among facial anomalies with an incidence of 1.5 to 5 per 100,000 births, and 1 per 100 cases of cleft lip and palate. The Tessier No. 7 clefts are unusual lesions that result from failure of the embryonic mandibular and maxillary processes to properly fuse and form the corners of the mouth. We experienced a case of Tessier No. 7 craniofacial cleft in a 1 day-old female patient who presented with a macrostomia and auricular malformation. The diagnosis was established by clinical and radiographic findings. A brief review of literature was made.
