Over the past years, hydrocolloid dressings have been introduced routinely in the treatment of various types of wounds. They provide a moist environment promoting autolytic debridement, and stimulate angiogenesis. However, long-term application often leads to inflammation of the skin in the immediate area of the ulcer, causing irritant dermatitis in many cases, but sometimes also leads to contact sensitization. A 32 year-old woman burnt herself by an iron, and presented to our clinic and was treated with Duoderm extrathin(R). Nine days later, she again presented with an erythematous oozing patch with edema, and allergic contact dermatitis was suspected. A patch test (TRUE test) was performed and a positive reaction to colophonium was obtained. Duoderm extrathin(R) contains hydrogenated rosin (colophonium) as the tackifying agent, so we could diagnose this case as allergic contact dermatitis due to the hydrogenated rosin in Duoderm extrathin(R). We report another case of allergic contact dermatitis due to Duoderm extrathin(R) in a 32 year-old woman.

PURPOSE: Survival outcome of locally advanced pancreatic cancer has been poor and little is known about prognostic factors of the disease, especially in locally advanced cases treated with concurrent chemoradiation. This study was to analyze overall survival and prognostic factors of patients treated with concurrent chemoradiotherapy (CCRT) in locally advanced pancreatic cancer. MATERIALS AND METHODS: Medical records of 34 patients diagnosed with unresectable pancreatic cancer and treated with definitive CCRT, from December 2003 to December 2012, were reviewed. Median prescribed radiation dose was 50.4 Gy (range, 41.4 to 55.8 Gy), once daily, five times per week, 1.8 to 3 Gy per fraction. RESULTS: With a mean follow-up of 10 months (range, 0 to 49 months), median overall survival was 9 months. The 1- and 2-year survival rates were 40% and 10%, respectively. Median and mean time to progression were 5 and 7 months, respectively. Prognostic parameters related to overall survival were post-CCRT CA19-9 (p = 0.02), the Eastern Cooperative Oncology Group (ECOG) status (p < 0.01), and radiation dose (p = 0.04) according to univariate analysis. In multivariate analysis, post-CCRT CA19-9 value below 180 U/mL and ECOG status 0 or 1 were statistically significant independent prognostic factors associated with improved overall survival (p < 0.01 and p = 0.02, respectively). CONCLUSION: Overall treatment results in locally advanced pancreatic cancer are relatively poor and few improvements have been accomplished in the past decades. Post-treatment CA19-9 below 180 U/mL and ECOG performance status 0 and 1 were significantly associated with an improved overall survival.

CD4+/CD56+ hematodermic neoplasm is a rare and aggressive lesion that affects many organs, and skin involvement is highly characteristic. It is also termed blastic natural killer cell lymphoma in the World Health Organization classification. Several origins of tumor cells have been proposed, but recent studies have shown a relationship with plasmacytoid dendritic cells. A 2-year-old boy presented with multiple bruise-like violaceous subcutaneous nodules and plaques on the trunk, upper and lower extremities. Histological examination showed small-to-medium-sized blastoid cellular infiltration in the dermis and subcutaneous tissue. Tumor cells were positive for CD4, CD56 and TdT, and negative for CD8, CD20 and MPO. It primarily affects elderly patients, but, in this case, occurred in an infant. Due to its rarity, we present a case of CD4+/CD56+ hematodermic neoplasm affecting a pediatric patient.

This study was conducted to draw out prevalence and the risk factors of diabetes mellitus and impaired fasting glucose for adults,(age 30-69). The subjects were 2096 adults, who had regular health examinations between January and December of 1999 at K Hospital in Seoul. The data was analyzed using chi-square test, unpaired t-test and logistic regression. Diabetes Mellitus and impaired fasting glucose were diagnosed by ADA (American Diabetes Association, 1997) criteria. The results were as follows: 1. Mens' prevalence of Diabetes Mellitus was 7.9% and womens' prevalence of Diabetes Mellitus was 3.8%. Mens' prevalence of impaired fasting glucose was 10.4% and womens' prevalence of impaired fasting glucose was 6.5%. Prevalences of Diabetes Mellitus and impaired fasting glucose increased with age. 2. Prevalence of Diabetes Mellitus and impaired fasting glucose of obese subjects (relative body weight>=162) was higher than that of overweight subjects (110<=relative body weight<=119) in men and women. 3. The diagnoses of Diabetes Mellitus and impaired fasting glucose increased with systolic blood pressure and triglyceride. 4. Significant factors associated with diabetes in the logistic regression best gut model were age, relative body weight, systolic blood pressure, triglyceride in men, and systolic blood pressure in women. In conclusion, as age, weight, systolic blood pressure and triglyceride get higher, Diabetes Mellitus and impaired fasting glucose prevalence also increases, porportionally.

BACKGROUND: Cell death is divided into two types, cell necrosis and apoptosis. In contrast to cell necrosis, an apoptotic cell is ingested by phagocytes and apoptosis is not accompanied by local inflammatory cells. Recently, apoptosis is considered to be involved in the pathogenesis of autoimmune diseases. OBJECTIVE: We investigated the presence of apoptotic cells in discoid lupus erythematosus, lichen planus, and psoriasis which are cutaneous autoimmune diseases, and also in erythema multiforme, which is not an autoimmune disease and of which characteristic in histopathologic features is necrotic keratinocytes. METHODS: A total of forty-six skin biopsy specimens were chosen. The specimen is made up of ten of each discoid lupus erythematosus, lichen planus, psoriasis, erythema multiforme and six of normal skin. We performed TUNEL stain on each specimen to observe apoptotic cells in the epidermis and dermis. The mean numbers of apoptotic cells were compared using the Kruskal-Wallis test and post hoc according to Conover. RESULTS: In discoid lupus erythematosus, apoptotic cells were observed as the most common disease in the epidermis and also in the dermis. In lichen planus, apoptosis was rarely observed in the epidermis, but was observed as the second common disease in the dermis. In psoriasis, apoptosis was rarely observed in both the epidermis and dermis. In erythema multiforme, apoptosis was observed in both the epidermis and dermis, and especially observed as the second common disease in the epidermis among four diseases. CONCLUSION: Apoptosis may contribute to pathogenesis of discoid lupus erythematosus and also in part to lichen planus and erythema multiforme. However, in psoriasis, apoptosis was rarely observed and resistance to apoptosis may be involved in the pathogenesis of psoriasis.

Lichen planus pigmentosus (LPP) is an uncommon variant of lichen planus, which manifests as hyperpigmented dark brown macular hyperpigmentations chiefly involving the face and upper extremities. The histopathologic changes consist of vacuolar degeneration of the basal layer, presence of dermal melanophages, and lichenoid lymphocytic infiltrations. LPP with exclusive localization in intertriginous areas is named as LPP-inversus, and is infrequently reported in previous dermatologic literature. A 16-year-old girl presented with several brownish to dark grayish patches on both axilla for 7 months. The lesions were asymptomatic and did not have preceding erythema. The patient had not come into contact with any chemicals and denied existence of previous allergy episodes, and her medical history was non-contributory. A skin biopsy from a brownish patch revealed vacuolar alteration of the basal layer, and band-like lymphocytic infiltration with pigment incontinence. We report a typical case of LPP-inversus with relevant literature.

Infectious mononucleosis(IM) is a benign self-limiting disease and result from a polyclonal B cell proliferation secondary to Epstein-Barr virus (EBV) infections. The infection is controlled by cytotoxic T cells triggered by EBV infected B cells. However, rare cases develop severe or fatal IM accompanied by hemophagocytic syndrome. We report a case of a 4-year-old girl who presented with high fever, hepatosplenomegaly, hepatic failure, pancytopenia and coagulopathy. Despite intensive treatment, the patient's condition deteriorated rapidly and died 3 days after admission. At autopsy, there was prominent infiltration of atypical lymphocytes with hemophagocytosis in multiple organs, especially liver, spleen and lymph nodes. Atypical lymphocytes were immunopositive for T cell markers and showed positive signal in EBV in situ hybridization.

Objective: To report the experiences of triplet pregnancies complicated by twin-to-twin transfusion syndrome (TTTS) treated with fetoscopic laser coagulation at a single center. Methods: Herein, we conducted a retrospective analysis to investigate the management and perinatal outcomes of triplet pregnancies with TTTS treated at a single institution between 2017 and 2022. Results: Seven of the 98 triplet pregnancies (7.1%) encountered were complicated by TTTS, and all were dichorionic triamniotic triplets. Of the seven triplet pregnancies complicated by TTTS, four were treated with fetoscopic laser coagulation at our center, at a median gestational age of 20 weeks. No procedure-related complications or maternal complications were observed. The survival rate was higher and perinatal outcomes were better in fetoscopic laser coagulation cases than in other management cases. Four donor and four recipient triplets survived, with a median gestational age of 33 weeks at delivery. Although there were no cases of poor neonatal outcomes, one case was diagnosed with white matter injury, suspected to be hypoxic-ischemic encephalopathy on postnatal investigation. Conclusion Fetoscopic laser coagulation is a feasible treatment option for triplet TTTS, provided the attending specialists have extensive experience with this technique.

Smoking is the most important environmental risk factor for the initiation and progression of periodontitis. However, its effect on periodontopathic Porphyromonas gingiavalis with respect to changes in physicochemical characteristics and prevalence of the pathogen in periodontitis patients remain to be elucidated. The present study was performed to examine the effect of cigarette smoking on the growth, protein profile, and prevalence of P. gingivalis genotypes in smoker and non-smoker periodontitis patients. The growth of P. gingivalis strains 2561 and 9-14K-1 in cigarette puffdissolved culture medium (CM) for 24 and 48 h was inhibited approximately 40% as compared to their growth in non-CM, but the growth of strains A7A1-28 and W50 was inhibited in CM by approximately 15%, revealing that they were relatively resistant to cigarette puff. In contrast, the growth of P. gingivalis HNA-99 was enhanced in CM by 11% after the 24-h incubation. However, its growth after the 48-h incubation decreased by 11% in CM. SDS-polyacrylamide gel electrophoresis and immunoblot analyses demonstrated that the expression of fimbriae in P. gingivalis strains 2561 and 9-14K-1, which were sensitive to cigarette puff, was reduced. On the other hand, the expression of fimbriae was rather increased in the cigarette puff-resistant strains A7A1-28 and W50. Decrease in autoagglutination of P. gingivalis 2561 grown in CM supported the fact that fimbrial expression in the cigarette puff-sensitive strain 2561 had been diminished. Genotypes of P. gingivalis in the subgingival plaque from 22 smoker and 32 non-smoker periodontitis patients was examined by 16S rRNA fimA gene-directed PCR. The prevalence of P. gingivalis was higher in the smokers (95.5%) than in the non-smokers (81.3%). Among the 5 fimA genotypes of P. gingivalis, genotype V, to which the cigarette puff-resistant strain HNA-99 belongs, was most prevalent in the non-smokers (57.4%). Although genotype V was found in 59.1% of the smokers, its prevalence in the smokers was second to that of genotype II. Genotype II, of which A7A1-28 is a representative, was observed to be predominant and seemed to be more closely related to smoking since its occurrence in the smokers was 63.6%, but only 21.9% in the non-smokers. The overall results suggest that cigarette smoking may directly affect physicochemical characteristics of P. gingivalis including the expression of fimbriae, which may play an important role in the resistance of the bacterium to cigarette puff. Therefore, P. gingivalis strains that can express fimbriae under cigarette puff-conditions may be favored to survive the conditions.
