"We retrospectively reviewed the results of 1,850 fine needle aspiration cytology (FNAC) of thyroid nodules performed from 1990 to 1991 in the Department of Pathology, Seoul National University Hospital. Among 1,528 cases and 322 cases aspirated by clinicians and a pathologist, 465 cases (30.4%) and 13 cases (4.0%) of the aspirates were inadequate, respectively. In 227 cases, correlation of the FNAC diagnosis and histologic diagnosis was done. Excluding the inadequate cases, the sensitivity for the detection of neoplasm (malignancy together with follicular adenoma) was 86.4% and the specificity was 70.7%. The overall diagnostic accuracy was 79.0%. There were 16 false-positive cases (7.0%), and 19 false-negative cases (8.4%). The predictive value of each cytologic diagnosis was 92% in papillary carcinoma, and 100% in Hashimoto's thyroiditis. The expectancy of malignancy was 52.8% in ""suspicious malignancy"" and 26.7% in ""atypical lesion""."

Three cases of successful pregnancy outcome after intensive care in the patients with rare mullerian anomaly of complete uterine septum, hypoplastic cervical duplication and longitudinal vaginal septum in infertility clinic are reported. These presented three cases are the reports of supporting the embryologic hypothesis of bidirectional mullerian development which fusion and resorption begins at the isthmus and proceeds simultaneously in both the cranial and caudal directions rather than the classical views of unidirectional(caudal to cranial) mullerian development. Thus, we present here three cases of rare mullerian anomaly and their pregnancy outcomes in an attempt to alert gynecologist to the possible occurrence of such a malformation. In 2 cases, successful pregnancy outcomes were achieved after abdominal or hysteroscopic uterine septotomy before pregnancy and in the last case, successful pregnancy outcome intensive obstetric care was achieved even under uncorrected uterine anomaly and complete removal of uterine septum resulted in uneventful postoperative courses at the same time of cesarean section.

BACKGROUND: Current non-invasive methods for evaluating the mediastinum by computed tomographic(CT) scan have limited sensitivity and specificity. The recently introduced PET was reported to be a more sensitive and specific method for the mediastinal staging of NSCLC(sensitivity:76-100%, specificity:81-100%) than CT or MRI. We assessed the usefulness of PET in the mediastinal staging of NSCLC. METHODS: We reviewed the medical records of NSCLC patients that had undertaken staging work-up by both CT and PET before thoracotomy between January 1997 and December 1998. A total of 23 patients were enrolled in the study(14 males and 7 females) with a mean age of 61±9 years. By comparing the clinical(CT and PET) and pathologic stagings, we evaluated the sensitivity, specificity, positive predictive value, negative predictive value and accuracy of PET in thoracic nodal staging. RESULTS: Sensitivity, specificity, positive predicted value and negative predicted value were 38%, 40%, 25% and 50% respectively for computed tomography, and 50%, 60%, 30% and 69% for PET. The accuracy of FDG-PET in our study was lower than that reported by previous other studies. CONCLUSION: Tne addition of FDG-PET to CT scanning has limited benefit for the thoracic nodal staging of NSCLC, but its value in our study was lower than that observed by others.

BACKGROUND: Shiitake dermatitis has been reported mostly from Japan and characterized by distinctive pattern of itchy skin eruption after the ingestion of raw shiitake mushrooms. OBJECTIVE: The purpose of this study is to investigate clinical, laboratory and histopathologic profiles about shiitake dermatitis occurring in Korea. METHODS: From 1997 to 2001, we had observed 58 patients with shiitake dermatitis and investigated clinical, laboratory and histopathologic aspects. RESULT: Most patients with shiitake dermatitis presented with a very strong itching sensation, which was accompanied with linearly grouped or disseminated small erythematous papules. 53 patients(91%) had noticed their skin eruption within 3 days after eating shiitake mushrooms. The involved sites were trunk, extremities, neck and face in decreasing order of frequency. Laboratory and histopathologic findings were nonspecific. In 33 patients(57%), the eruption occurred after eating boiled or panbroiled shiitake mushrooms. CONCLUSION: In this study, clinical, laboratory and histopathologic findings of shiitake dermatitis were almost consistent with the previous reports. But, contrary to the previous reports in Japan, many cases with shiitake dermatitis occurred on eating sufficiently boiled or cooked shiitake mushrooms. This may imply another eiologic factor different from thermolabile toxin.

OBJECTIVE: To provide epidemiologic data of the pressure sores and to determine the most effective prevention and treatment methods. METHOD: Seventy patients with pressure sores who were admitted to the Rehabilitation Hospital, Yonsei University College of Medicine from 1991 to 1995 were included in this study. RESULTS: The average age of the patients was 36. Traffic accident was the most common(46 cases) cause of injury, followed by falling injury. Thirty-one patients developed pressure sores at home, while 39 patients in various hospitals. According to Frankel's classification, 51 cases were Frankel A, 13 cases were Frankel B, 5 cases were Frankel C and none was Frankel D. Sacrum was the most common site of the sore followed by buttock, ischial tuberosity, greater trochanter, and coccyx. Among many factors investigated, the anemia and hypotension had a significant correlation with the healing time. The treatment methods were variable among the patients depending on the size and severity of the sores. The severe and larger lesions required more surgical managements. CONCLUSION: The results support that an intensive prevention is necessary at homes as well as at the hospitals. More educational programs should be provided not only for the patients, but also for the hospital personnels.
