BACKGROUND: A clinical study of rosacea has never been reported in Korea. OBJECTIVE: The purpose of this study was to elucidate the clinical observations of rosncea. METHODS: During a 5-year-period from Jan. 1990 to Dec. 1994, 133 patients were evaluated with regard to age, sex, location of skin lesions, clinical type, duration, and precipitating factors. RESULTS AND CONCLUSIONS: 1. Of the 7,787 cases amongst outpatients, 133 cases(1.7% ) were dignosed with rosacea. Of there 46 were male patients and 87 females, giving a sex ratio of 1:1.9 in favor of females. 2. The most common type of rosacea was vascular rosacea(60.2%) 3. The average duration of rosacea was 3.4 years. 4. Rosacea afflict persons aged 40-49 most frequently. 5. The predilection sites of the rosacea were : cheek(42.9%), nose(23.3%), entire face(11.3%), cheek & nose(9%), zygomatic area(6.8%), extra-facial area(3.8%), forehead(2.9%). 6, The aggravating factors of rosacea were : unknown cause(32.3%), coffee & tea(18%), alcohol(13.5%), emotional stress(10.5%), sun exposure(9.8%), multi-factoral(7.5%), drugs(steroids)4.6%).

Ecthyma Gangrenosum is a rapidly progressing skin infection charact,erized by edema, hemorragic bullae and necrosis. Ecthyma Gangrenosum occurs almost exclusively in severely imrnunocompromised patients during the course of pseudomanas aeruginosa septisemia. A 5 month-old boy was transferred to our department because of multiple well defined central necrotic black-colored large erythematous bullae. In the bacterial cultures of skin, stool and liver aspiration fluid, Pseudomonas aeruginosa was grown. In the abdominal ultrasonogram and computed tomogram, the multiple liver abscess, hepatomegaly and ascites were shown on both hepatic lobes. Herein we report a case of ecthyma gangrenosum associated with liver abscess.

In the summer of 1969 from July through October, authors carried out a study of susceptibility in adult female bed bug(Cimex lectularius) in order to ascertain any development of resistance to insecticides in Korea. The test to DDT and Dieldrin was performed in laboratory by the continuous exposure of residues method, with standard impregnated paper used for adult mosqitoes. Some results so far obtained can be summarised as follows: LC(50) were 2.839% in DDT and 0.167% in Dieldrin. The resistance has been arisen 2.4-2.9 times in DDT and 1.6-2.4 times in Dieldrin as compared with London laboratory strain, but they were susceptible 1.4 times in DDT and 180 times in Dieldrin as compared to Israel resistance strain.

The clinicopathologic features of a Korean patient with adult T-cell leukemia/lymphoma(ATLL) are presented. A 51-year-old man, who has lived in Korea since birth, had multiple cutaneous nodules and multiple lymphadenopathy for the previous two months. A histopathologic study of the lymph node and skin lesion revealed T-cell non-Hodgkin's lymphoma of pleomorphic type, medium and large cell type. Peripheral blood examination showed leukemic features with 30% of abnormal lymphoid cells. HTLV-I proviral DNA pX region was detected in the DNA from peripheral blood mononuclear cells(PBMC) and the specific gag, pol, and env HTLV-I sequences were detected in the lymph node using polymerase chain reaction technique. Human T-cell leukemia/lymphoma type I(HTLV-I) antibodies were present in the serum. An immunophenotypic study of the lymph node revealed CD4 positive and CD8 negative helper/inducer T cell type surface markers. This case is the acute type, i.e. prototypic ATLL. He was treated with an intensive chemotherapy including cyclophosphamide, etoposide, doxorubicin, vincristine, and prednisone. Despite initial transient improvement, the tumor progressed after three cycles of the regimen and became refractory to further chemotherapy. These clinicopathologic findings, including the immunophenotypic analysis, established with certainty the diagnosis of HTLV-I-induced adult T-cell leukemia/lymphoma.

BACKGROUND: In Korea, the incidence of varicella has increased despite the introduction of a universal one-dose vaccination for children aged 12–15 months in 2005. A previous study demonstrated that the vaccine effectiveness was insufficient to prevent against varicella. We assessed the effect of the varicella vaccination on disease severity. METHODS: Epidemiologic investigation of varicella cases in Seoul metropolitan area from 2015 to 2017 were used. Varicella-related symptoms such as rash were determined by the clinical practitioners. Disease severity of patients was assessed by the number of skin lesions and divided into mild (≤ 50) and moderate (51–249) to severe (≥ 250). Unconditional logistic regression analysis was performed and age was controlled. RESULTS: Among a total of 1,008 varicella cases reported, 869 cases were breakthrough cases and 139 were unvaccinated cases. The risk for occurrence of moderate-to-severe disease in the breakthrough group was 0.57 times less than that of the unvaccinated group. CONCLUSION: These data suggest that national varicella vaccination may have a significant effect on attenuation of disease severity in children.

Glucocorticoid receptor (GR) functions as a suppressor of inflammation by inhibiting the expression of many cytokine gene activated by NF-κB. The goal of this study is to investigate the mechanism by which GR repress NF-κB activation in lung epithelial cells. We used A549 and BEAS-2B lung epithelial cell lines. Using IgGκ-NF-κB luciferase reporter gene construct, we found that dexamethasone significantly suppressed TNF-α-induced NF-κB activation and the overexpression of GR showed dose-dependent reduction of TNF-α-induced NF-κB activity in both cell lines. However, DNA binding of NF-κB induced by TNF-α in electromobility shift assay was not inhibited by dexamethasone. Super shift assay with anti-p65 antibody demonstrated the existence of p65 in NF-κB complex induced by TNF-α Western blot showed that IκBα degradation induced by TNF-α was not affected by dexamethasone and IκBκ was not induced by dexamethasone, neither. To evaluate p65 specific transactivation, we adopted co-transfection study of Ga14-p65TA1 or TA2 fusion protein expression system together with 5xGa14-luciferase vector. Co-transfection of GR with Ga14-p65TA1 or TA2 repressed luciferase activity profoundly to the level of 10-20% of p65TA1- or TA2-induced transcriptional activity. And this transrepressional effect was abolished by co-transfection of CBP or SRC-1 expression vectors. These results suggest that Gr-mediated transrepression of NF-κB in lung epithelial cells is through competing for binding to limiting amount of transcriptional coactivators, CBP or SRC-1.

We report a case of a 13-year-old girl with acute lymphoblastic lymphoma-leukemia, who presented with a cardiac metastasis in the right ventricle, resulting in a pulmonary embolism. At the time of her leukemia diagnosis, a cardiac mass was incidentally found. The differential diagnosis for this unusual cardiac mass included cardiac tumor, metastasis, vegetation, and thrombus. Empirical treatment was initiated, including anticoagulation and antibiotics. She underwent plasmapheresis and was administered oral prednisolone for her leukemia. Five days later, she experienced sudden hemodynamic collapse and required extracorporeal membrane oxygenation insertion and emergency surgery. These interventions proved futile, and the patient died. Pathology revealed that the cardiac mass comprised an aggregation of small, round, necrotic cells consistent with leukemia. This is the first known case of acute lymphoblastic leukemia presenting as a right ventricular mass, with consequent fatal acute pulmonary embolism. A cardiac mass in a child with acute leukemia merits investigation to rule out every possible etiology, including vegetation, thrombus, and even a mass of leukemic cells, which could result in the fatal complication of pulmonary embolism.
