Tinea pedis is frequently found in those people with poor hygine and in hot and humid environments. The authors investigated the clinical, epidemiologicol a id mycological characteristics of tinea pedis in 138 sewerage workers attending a sewerage plant in Seoul. Tinea pedis was found in 82, with a prevalence of 59.4%. The prevalence of tinea pedis increased with age and the period working at sewerage plant, however, there was no statistical significance. Also there was no difference in the prevalence of tinea pedis between the clerical workers and the field workers. Positive rate for KOH smear was 73.2%, and culture positive rates were 42.7%, producing 35 strains of dermatophytes. Twertyeight strains of Trichophyton Rubrum and 7 strains of Trichophyton mentagrophytes were isolated. Twentyseven yeast-form colonies were isolated, and Trichosporon beigelii was foungl in 19 samples. Most of the yeast forms were found mixed with dermatophytes and moulcis, However, 6 were isolated from direct smear positive cases and yieIded pure colonies of yeast. These included 4 cases of T. beigelii, 1 case of Candida parapsilosis, and 1 case of Candida hormicola. In view of the recent report of these fungi as pathogenic organism, these isolates, rspecially T. beigelii, were considered as a causative agent of tinea pedis in certain groups like sewerage workers.

Toxic shock syndrome (TSS) is a rare but life-threatening illness that is mainly caused by toxigenic strains of Staphylococcus aureus. Although TSS is classically known to be associated with tampon use, the number of TSS cases with non-menstrual causes such as skin and soft tissue infection has been increasing. Tattooing can result in several complications such as localized and systemic infections, inflammatory skin eruptions and neoplasms. We recently experienced a 26-year-old man diagnosed with typical TSS following tattooing. He complained of fever, chills and erythematous rash at tattoo site. Subsequently, the patient developed sign of shock. The skin cultures on the tattoo site were positive for methicillin-sensitive Staphylococcus aureus. The patient was successfully treated with vasopressor infusion and intravenous antibiotics and was discharged without complications. On discharge from the hospital 7 days later, desquamations on the tattoo site, fingers and toes were observed.

PURPOSE: In old age, abdominal aortic aneurysm (AAA) is not a rare disease and potentially fatal. Also, there has been a lack of concern for this disease in the emergency department. Our study investigated the clinical characteristics of AAAs seen in the emergency center to assess the needs of the diagnostic approach to this disease in the emergency center. METHODS: Eighty patients with an AAA between Jan. 1995 and Jul. 2002 were enrolled. Data were obtained from a retrospective review of medical records. We analyzed the clinical characteristics of the AAA on the basis of the patient 's age and sex, risk factors, presenting symptoms and signs, physical findings, diagnostic tools, and findings. RESULTS: AAAs were predominant in males (82.5%). A smoking history (57.5%), old age over 65 (71.3%) and hypertension (50.0%) were the most common risk factors. In this study, the initial diagnosis of a AAA was mostly determined by the existence of a pulsating abdominal mass, and the overall sensitivity of a pulsating abdominal mass was 57.5%. Although the most common presenting symptom was abdominal pain(51.3%), about one third of the patients had no subjective symptoms. Twenty-one of the patients had a ruptured AAA at the time of diagnosis. There was no remarkable difference in the incidence of large AAA (> 5 cm) or ruptured AAA between elderly (> 65years) and the young (< 65 years). CONCLUSION: Because of the absence or vagueness of symptoms and signs, an AAA might be initially excluded without a careful examination. For the early detection and prevention of a ruptured AAA, emergency medical doctors should carefully evaluate and assess patients with risk factors even though they have non-specific symptoms of the gastrointestinal or urinary system.

PURPOSE: The internet is a vast resource for consumers. The internet is a decentralized, global medium, so quality management of health information is difficult for the lay person. Basic Life Support (BLS) is basic information provided for the lay person in the province of emergency medicine. The writers searched for BLS information on Korean and Japanese Web sites and assessed the quality of that information. METHODS: We used the search engine 'Yahoo! Korea' in Korea and 'Yahoo! Japan' in Japan. The search references were 'Basic Life Support' and 'Cardiopulmonary Resuscitation (CPR)'. The assessment was based on three 'Credibility' and seven 'Content' factors. 'Credibility' factors composed of 'Source', 'Context' and 'Currency'. 'Content' factors composed of six factors of accuracy of six course of BLS and one factor of 'Original Source Stated'. We make our own criteria for each factors. And, If the web site fitted the criteria, we give 1 point, if not, give 0point. So, 'Credibility' factors point is 3 points full mark and 'Content' factors point is 7 points full mark. RESULTS: Eight Korean and fifteen Japanese sites were found as a result of the search. No difference in 'Credibility' factors existed between the two nations' web sites. There was, however, a statistical difference in the 'Content' factors between the two nations' web site. The mean of 'Content' factors points is 3.75 and 5.06 in 7 points full mark, Korean web site and Japanese web site respectively. CONCLUSION: Improvement in the quality of BLS on internet web sites is needed, especially BLS on 'Recovery position', 'Assessment of circulation', and 'Cardiac comp ression'.

BACKGROUND: The Technicon Immuno I utilizes various enzymatic kinetic analysis with colorimetric detection and magnetic particles. We evaluated this fully automated random-access immunoassay system which can perform latex agglutination and magnetic-separation sandwich/ competitive immunoassay. METHODS: We evaluated the assay precision, lower limits of detection, linearity, recovery, sample to sample carry-over, analytical interferences and comparison with other various methods for the following analytes: thyroxine (T4), thyroid stimulating hormone (TSH), free thyroxine (FT4), luteinizing hormone (LH), follicular stimulating hormone (FSH), prostate specific antigen (PSA), alpha-fetoprotein (AFP), carcino-embryonic antigen (CEA), CA 19-9, and digoxin. RESULTS: Satisfactory results were obtained for within-run and between-day precision in most analytes. Lower limits of detection were slightly higher than claimed by the manufacturer. The linearity was acceptable, but there were proportional errors for CEA and FT4. The recovery rates were also good except for PSA. Sample to sample carry-over was not detected. No significant analytical interference was caused by hemoglobin (up to 2,000 mg/L), lipid (up to 85 mmol/L) and bilirubin (up to 325 mol/L) except for digoxin, FT4 and PSA. The Technicon Immuno I assay correlated well with the comparison methods in most analytes, but the proportional biases were found for PSA and LH. CONCLUSIONS: The Technicon Immuno I is a satisfactory system for clinical use in most cases but more study would be requried for FT4. Especially, this system can replace the radioimmunoassay for FSH and LH.

BACKGROUND: Serum high density lipoprotein (HDL)-cholesterol level is used as an assessment of the risk of coronary heart disease. In this study, we evaluated direct measurement of HDL- cholesterol in serum with polyethylene-modified enzymes and sulfated alpha-cyclodextrin. METHODS: We evaluated the precision, the lower limit of detection, the recovery rate, the linearity, the interference for hemoglobin and the comparision with the result of HDL-cholesterol measured by selective precipitation method. We also studied the specificity of this direct method for very low density lipoprotein (VLDL) and low density lipoprotein (LDL). RESULTS: The total imprecision was 3.8% (low), 3.5% (middle), 3.2% (high). The lower limit of detection was 0 mg/L. The recovery rate was satisfactory. The linearity was also (r2=0.99). This method showed a good correlation (r2=0.97) with the selective precipitation method in HDL- cholesterol measurement. VLDL-cholesterol (up to 300 mg/L) increased HDL-cholesterol only less than 3% but increased VLDL-cholesterol to 400 mg/L, more than 750 mg/L caused 5% and 15% of overestimation of HDL-cholesterol, respectively. LDL-cholesterol (142-1,073 mg/L) increased or decreased HDL-cholesterol by some degree (about 15%). Hemoglobin (up to 3,000 mg/L) did not influence this assay. CONCLUSIONS: The direct measurement of HDL-cholesterol is satisfactory method in HDL- cholesterol measurement in good analytical performance and may be anticipated to reduce workload of laboratory because the sample pretreatment is not necessary.

T cell immunity and phagocytic activity were studied in the blood of patients with IgA nephropathy in order to clarify their roles in the pathogenesis of IgA nephropathy. The percentages of total T lymphocytes, helper T cell and suppressor T cells were significantly reduced in patients. A significantly elevated helper T cell/suppressor T cell ratio in patients showed a predominant reduction in suppressor T cells. There was a significant relationship between histologic findings and helper T cell/suppressor T cell ratio in patients. Natural Killer (NK) cell activity was significantly reduced but the lymphocyte response after phytohemagglutinin (PHA) stimulation was not in patients. ConA-induced suppressor cell activity was not depressed despite of a decrease in suppressor T cells in patients. Phagocytic activity of polymorphonuclear leucocytes (PMNs) ingesting yeasts was significantly reduced in patients. Also an inverse correlation was found between serum IgA levels and phagocytic activity of PMN. It is concluded that suppressor T cell defects, depressed phagocytic activity and impaired NK cell activity may play a role in the pathogenesis of IgA nephropathy.

Primary small cell neuroendocrine carcinoma in stomach is known to be very rare and only the twelve cases have been reported in the English literature. This tumor appears to be analogous to small cell carcinoma and carcinoid tumors of the lung, and is characterized by a very aggressive clinical course. Recently, we have experienced a 68-year-old man with primary small cell neuroendocrine carcinoma in the stomach, which had liver metastasis and peritoneal seeding. A positive Grimelius stain was present and immunohistochemical studies revealed positivity for neuron-specific enolase in the tumor. For its rarity, we report this case with review of literatures.

Experimental & Molecular Medicine 2006;38(1):94-99
GITR (glucocorticoid-induced TNF receptor) is a recently identified member of the TNF receptor superfamily. The receptor is preferentially expressed on CD4+CD25+ regulatory T cells and GITR signals break the suppressive activity of the subset. In this study, we wanted to reveal the in vivo function of GITR in chronic graft-versus-host disease (cGVHD), a lupus-like autoimmune disease. A single injection of anti-GITR monoclonal antibody (DTA-1) was effective in blocking the progression of cGVHD in the parent-into-F1 model. Treatment of DTA-1 significantly decreased levels of IgG1 anti-DNA autoantibody, inhibited glomerulonephritis, and increased survival. The DTA-1-mediated inhibition of autoantibody production correlated with deletion of B cells and could occur independently of CD4+CD25+ regulatory T cells. Our results indicate that anti-GITR monoclonal antibody may be used as a potential immunotherapeutic agent for preventing cGVHD.
