Normal C3WHeN strain mice exposed to topical 8inethoxypsomlen plus long wave ultraviolet (PUVA) showed a reduction in contact hypersensitivity, (CH) which was localized to the skin in the area of PUVA treatment (local suppression), whereas systemic PUVA treatment caused diffuse suppression of CH reaction, regardless of the application site of 2,4-dinitro-1-fluorobenzene (DNFB). There seem to be two different mechanisms responsible for CH reduction by PUVA. Local suppression by topical PUVA treatment was thought to be a result of blocking the afferent phase of immune response, it was associated with a lack of CH effector cells in the peripheral lymph nodes and could not be reversed by indomethacin treatment. Diffuse suppression induced by systemic PUVA treatment seemed to be associated with blocking of egress of effector cells from the regional lymph nodes, this depressed CH response was prevented when indomethacin was administered before PUVA treatment.

Pneumomediastinum, pneumothorax and subcutaneous emphysema are uncommon in pediatric practice, but they may be rarely ocured in association with respiratory distress and excessive ressusciation in the neonatal period, and as a complication of bronchial asthma, measles in childhood. And also, there was a report of a few cases that developed to pneumomediastinum and subcutaneous emphysema caused by vomiting in patient of diabetic coma. It is rare so far in this country that above events are complicated by miliary tuberculosis, but they may lead the patient to fatal and lifethreatening conditions, even though we perform a considerable medical treatment for that. We presnted 3 cases of 6 month 20 days old female infant, and each 10 year and 11 year old boys, developed to pneumomediastinu, pneumothorax and subcutaneous emphysema, and suddenly expired during hospital treatment of miliary tuberculosis. And, we reviewed the literatures, too.

Inferior sinus venosus defect is a rare lesion in which there is a large interatrial communication adjacent to the atrial connection of the inferior caval vein. The defect is located posteriorly and inferiorly, outside the confines of the true atrial septum, and partial anomalous pulmonary venous connections are the rule. We underwent surgical repair in four patients with inferior sinus venosus defect and partial anomalous pulmonary venous return. There were three males and one female with an age range from four months to 25 years. A cross-sectional echocardiogram and cardiac catheterization had been performed preoperatively in all patients, but the correct diagnosis had been made in only one case. Surgical repair was indicated due to congestive heart failure, and one patient of 4-month-old needed urgent operation. The repair was accomplished by suturing a untreated autologous pericardial patch to the right of the pulmonary veins, so that the defect was closed and all the pulmonary venous blood was directed to the left atrium. The preoperative knowledge of the unusual anatomy allows the surgeon to repair the anomaly without difficulties. For the patients in whom interatrial communication and anomalous pulmonary venous return are suggested, surgeon has to pay careful attention to the anatomical landmarks to avoid incorrect placement of the patch.

Tsutsugamushi fever is a serious febrile disease outwardly similar to malaria and various arboviral infections. The endemic area is Asia-Pacific. This disease are generally associated with disturbed habitats favoring large populations of vector larval trombiculid mites. Therapy with tetracycline, chloramphenicol or ciprofloxacin is currently recommanded. Unfortunately these drugs is suboptimal for children and pregnant women. Recently, azithromycin has been proven to be effective in therapy of scrub typhus. There is no evidence that azithromycin causes adverse reaction to developing fetus or children. We report four cases of tsutsugamushi fever in children successfully treated with azithromycin. This is the first report describing clinical application of azithromycin to tsutsugamushi fever in Korean children.

Adenocarcinoma of small intestine is rare disease, but its incidence of iluem is the least of small intestinal adenocarcinoma. Its rarity and vague symptoms results in delayed diagnosis, treatment and poor prognosis, Recently we experienced a 65 years old man of ileal adenocarcinoma with liver metastasis, which does not obstuct intestinal lumen, We treat the metastatic tumor with chemoembolization(lipiodol and doxorubicin) through the hepatic artery and so we report the case with review of literature.

In this study, trends in the sales of antimicrobials for use in livestock facilities and fisheries from 2003 to 2012 were investigated with regard to antimicrobial group, antimicrobial usage, and animal species. The overall amount of antimicrobials sold each year from 2003 to 2007 was 1,500 tons, after which they decreased, with the lowest sales being 936 tons in 2012. The total volume of antimicrobials used for feed additives decreased markedly by 94% from 2003 to 2012, which was mainly attributed to banning of feed additives. However, antimicrobial consumption through self prescription by farmers for disease prevention and treatment increased by 25% from 2003 to 2012. The largest volume of antimicrobials sold was for use in pigs (48~57%), followed by poultry (18~24%), fisheries (11~25%), and cattle (5~8%). Tetracycline was the highest selling antimicrobial, followed by penicillins and sulfonamides, although the overall sale of all three antimicrobials gradually decreased over the study period. This study demonstrated that the total consumption of antimicrobials has gradually decreased since 2008. Nevertheless, usage by nonprofessionals increased, which can ultimately cause emergence and spread of antimicrobial resistance. Thus, early establishment of veterinary prescription guidelines for prudent use of antimicrobials is urgently needed in Korea.

PURPOSE: The aim of this study was to describe the experience of teaching emergency management and cardiopulmonary resuscitation to medical students in Busan. METHODS: Study participants were 59 medical students in Busan. An eight-day curriculum in the emergency management and cardiopulmonary resuscitation was developed. They completed all class sessions and two drill/practical examinations taught by our interdisciplinary team from July 21 through 30, 2003. Each class is approximately 2 hours and reading assignments are given at the end of each class. Also included are practical, table-top and team-building exercises. The participants completed self-reported questionnaires for the education. RESULTS: About establishment and environment of the education, respondents answered with `very good' were 14%. About overall theoretical lecture, respondents answered with `very helpful' were lower than 40%. Especially, favorable evaluation for the medical lectures was lower than that of other lectures. Students generally enjoyed their emergency medicine experience as it is often their first opportunity to assume primary responsibility for patient care. About overall practices, respondents answered with 'very helpful' were higher than 60%. CONCLUSION: The authors found that medical students prefer opportunities to hone procedural skills than to hear theoretical lectures. Also, medical students are welcome to hear theoretical lectures that consists of emergency management related contents, not academically medical contents. This curriculum should be tailored to fulfill learner's requirements.

The purpose of this study was to investigate the prevalence of Brachyspira species and antimicrobial susceptibility of Brachyspira (B.) hyodysenteriae isolates in Korea. A total of fifty-five Brachyspira species were isolated; five (1.0%) beta-hemolytic Brachyspira species and 50 (10.4%) weak hemolytic Brachyspira species from 116 different diarrheic pig samples and 367 apparently normal pig samples. In farm level, beta hemolytic and weak hemolytic Brachyspira species were detected in 7.4% (5/68) and 19.1% (13/68) of tested pig farms, respectively. By phenotypic and genotypic characterization, all beta hemolytic Brachyspira isolates was classified as group I (B. hyodysenteriae), whereas weak hemolytic Brachyspira species isolates were group III (B. innocens or B. murdochii). B. hyodysenteriae isolates showed high level of minimum inhibition concentrations to macrolide antimicrobials. This study shows that the prevalence of pathogenic B. hyodysenteriae in pigs is low but antimicrobial resistance of the pathogens is high in Korea. This is the first report of the prevalence of Brachyspira group III and antimicrobial susceptibility of B. hyodysenteriae in pigs in Korea. Our results could provide basic data for the management and treatment guidelines of Brachyspira infection.
