Polydactyly is the most common congenital anomaly of the upper limb. Polydactyly is classified as preaxial polydactyly(thumb), central polydactyly(index, middle and ring fingers), and postaxial polydactyly(little finger) by the site of the extra digit. A 3-day-old female newborn had a 1.5 * 1.0cm sized flesh color ed pedunculated sac like mass on the proximal phalanx of her right thumb since birth. A roentgenogram on the hand revealed no bony abnormalities of the digit and the mass contained no bony structures. The stalk of the mass was cut by the CO2 laser. On histopathological examination, a cartilage structure was found in the loosely arranged, edematous dermis and the overlying epidermis was flattened. The clinical and histological findings support the diagnosis of preaxial polydactyly. We report this interesting case of preaxial polydactyly with a review of the literature.

The incidence of skin diseases in the hospital practice cannot give a true picture of their prevalence in the population served. Nevertheless the hospital incidence figures usually offer the only available means of assessing prevalence, and therefore provide us with a potentially valuable source of information on the ecology of many skin disorders.

A 53-year-old man developed some erythematous follicular macules accompanied with tingling sensation on both shoulders. Histologic finding showed a dense lymphocytic infiltrate around the infundibular portion of the follicle, where separation of the dermoepidermal junction was seen. The insect, obtained from the skin lesion, was identified as a larva of an Ap- hid

BACKGROUND: Langerhans cells (LC), keratinocytes and Thy-1+ dendritic epidermal cells(DEC) are epidermal cells which are known to have important roles in inflammatory or immunologic skin disorders. Allergic contact dermatitis(ACD) is a prototype of a delayed hypersensitive reaction in which LC, keratinocytes and T lymphocytes play an important role. The role of LC in ACD is well known, but the role of Thy-1+ DEC is not yet fully revealed. Futhermore, the mechanism of irritant contact dermatitis(ICD) is not known and more study is required on the interaction between these epidermal cells in ICD. OBJECTIVE: The aim of this study is to observe the changes of these cells in ACD and ICD and to discuss their possible roles in the disease precess. MEHTODS: We evoked ACD with DNFB and ICD with croton oil in BALB/c mice and observed the morphologic changes of LC, Ia+ keratinocytes, and Thy-1+ DEC by immunoperoxidase staining when the inflammation was at its peak and at the resolution state. RESULTS: 1. In the control group, LC were evenly distributed and their average number was 1147+/-132/mm*. Thy-1+ DEC were slightly bigger than LC and showed uneven distribution. The average number of Thy-1+ DEC was 57+/-69/mm* Ia+ keratinocytes did not appeared. 2. On the 1st day of DNFB challenge, the number of LC was significantly decreased and their size and dendritic processes were increased when compared to those of the control group. Most of the keratinocytes showed Ia antigen expression on their surfaces. 3. On the 12th day of DNFB challenge, no significant changes in the number and morphologyof LC were noted when compared to the cotrol group, Ia+ keratinocytes were not observed. 4. there were no significant changes in the number and morphology of Thy-1+ DEC in ACD on the 1st and 12th day after DNFB challenge. 5. On the 2nd day after croton oil application, the number of LC was significantly decreased but the morphology not significantly changed. Ia+ keratinocytes were not observed. 6. On the 20th day after croton oil application, the number of LC was significantly increased but the morphology was not significantly changed. Ia+ keratinocytes were not observed. 7. There were no significant changes in th number and morphology of Thy-1+ DEC in ICD on the 2nd and 20th day after application of croton oil. Ia+ keratinocytes were not observed. CONCLUSION: In can be deduced that the LC have important roles in the mechanisms of both ACD and ICD reactions. Ia+ keratinocytes have an important role mainlyin the inflammatory precess of ACD. In addition, since the changes of the number of Langerhans cells in ACD and ICD showed different time courses and Ia+ keratinocytes appeared only in ACD, we hypothesized that different pathways of inflammation exist in ACD and ICD, and different cytokines may be responsible. It is probable that Thy-1+ DEC does not have any significant role in the inflammatory process of both ACD and ICD.

OBJECTIVE: The goal of this article is to analyze the clinical characteristics of intramural pregnancy through the review of currently available 36 case reports. METHODS: A comprehensive computer literature search was performed in MEDLINE and EMBASE database from 1966 to 2003. And domestic literature search was preformed in KSOG database. After data collection, we reviewed and analyzed meaningful clinical variables of each case report. RESULTS: 36 articles were included. The age at diagnosis ranged from 20 to 41 years old, and the mean age was 31.2 years (S.D.:5.6). The gestational period at diagnosis ranged from 6th to 30th weeks, more than half of the cases occurred from 6th to 10th week (58.3%). Significant risk factors were history of dilatation and curettage (47.2%) and history of cesarean section (25.0%). Common clinical symptoms and signs were vague abdominal pain (58.3%) and vaginal bleeding (54.2%) in unruptured case, and sudden onset of severe abdominal pain (100%) and muscle guarding (75.0%) in ruptured case. The preoperative diagnostic accuracy was 0% before introduction of ultrasonography into the clinical practice, 48.2% after ultrasonography was available. Of 36 patients, 27 patients (75.0%) were treated with laparotomy, and 5 patients (13.8%) were treated with methotrexate. Survival outcome of fetus was very poor. Only in 1 case, the pregnancy persisted beyond the 30th week, and the fetus survived after cesarean hysterectomy. CONCLUSION: With the advanced diagnostic tools and close monitoring of patients, we can improve the diagnostic accuracy and clinical outcome of intramural pregnancy.

BACKGROUND: The major serious risk of blood transfusion is post-transfusion hepatitis. Currently HBsAg, anti-HCV and serum alanine aminotransferase (ALT) assays are screened for potential blood donors to prevent transfusion associated hepatitis in Korea. But the effectiveness of serum ALT as a surrogate marker for the screening of non-A, non-B hepatitis is controversial. The present study was designed to evaluate the prevalence of hepatitis markers in Korean blood donors and the usefulness of ALT as a surrogate marker. METHODS: The prevalence rates of anti-HCV and HBsAg were analyzed by age, sex and ALT cut-off level in 405,931 blood donors. The current anti-HCV EIA (LG HCD 3.0 ) comparing to anti-HCV confirmatory immunoblot assay (LG HCD confirm ) and ALT test were evaluated. RESULTS: The positive rate of HBsAg was 3.32% and higher in male across all age group (p<0.01). The rate increased as age increases up to thirties and decreased thereafter. The positive rate of anti-HCV was 0.24% in EIA, and higher in female across all age group except for teenage group (p<0.01). The rate increased as age increases up to fifties (p<0.01). Results of immunoblot assay showed 64% disaccordance with that of EIA and the rate of disaccord was high in female and young age group. The rate of mixed infection of hepatitis B and C was 0.003%. ALT level was within normal range in 95.2% of donors, and the prevalences of HBsAg and anti-HCV were higher as ALT increased above normal level (p<0.01). The sensitivity of ALT in identifying hepatitis C was 34.5% at 45 IU/L, and 22.8% at 65 IU/L. The most accurate cut-off level of ALT for hepatitis C was 23 IU/L in Receiver-Operating Characteristic (ROC) plot and the sensitivity and specificity were 65.5% and 79.9% at that level. CONCLUSION: In contrast to HBsAg, the prevalence rate of anti-HCV showed different pattern in that it was higher in female and continuously increased up to fifties. Confirmatory assay for hepatitis C should be done for the high false positivity of current anti-HCV EIA. The sensitivity and positive predictive value of ALT was so poor that ALT was not found to be useful as a surrogate marker for hepatitis C, but the discontinuance of ALT testing of blood donors needs to be evaluated by further studies.
