BACKGROUND: Cleaning and disinfection of fiberoptic bronchoscope requires careful attention, especially to mycobacterium species because the contamination of mycobacteria could raise confusion on diagnosis. Recently, we detected contamination of Wydex(R) solution used in bronchoscope washer with Mycobacterium chelonae. In this study, we evaluated the mycobactericidal effect of 12 kinds of disinfectants for M. chelonae. METHOD: To evaluate the bactericidal effect of Wydex(R) 2%, Cidex(R) 2.25%, Cidex(R) 3%, Bacteriokiller (BK) disinfectant, Perasafe(R), HICLO-S(R), Lamicine(R), ethanol, Instrusept(R), Virkon(R), Betadine(R), and Vipon(R) against M. chelonae, culture was performed after exposure of two M. chelonae strains (ATCC 35749, the type strain and the strain isolated from contaminated Wydex(R) solution) to each disinfectant solution. The growth of organism was examined for up to 8 weeks. RESULTS: Growth of M. chelonae (reference strain of ATCC 35749 and isolated strain) was observed after a week incubation for Wydex(R) 2%, Cidex(R) (2.25%, 3%) and control. For BK disinfectant and Perasafe(R), they grew after 2-3 weeks, and 3-4 weeks, respectively. For HICLO-S(R) and Lamicine(R), only the contaminated strain grew after two and three weeks, respectively. For ethanol, Virkon(R), Betadine(R), Vipon(R), and Instrusept(R) , growth was not observed from either strain. CONCLUSIONS: On the basis of these results, Instrusept(R), virkon(R), ethanol, Betadine(R), and Vipon(R) were effective for the disinfection of M. chelonae. Especially, Instrusept(R) was thought to be useful as a disinfectant for bronchoscopes because it has advantages including non-corrosiveness, chemical stability, and non-irritativeness. And additional washing with ethanol might be effective. The finding that strain isolated from contaminated bronchoscopes was more resistant to disinfectants than reference strain suggested that the more resistant strains are selected throughout the improper disinfection.

Zipper entrapment injuries require a technique to safely and promptly release the entrapped tissues to prevent complications. Herein, we report an 8-year-old girl whose eyelid wassuccessfully released from an entrapping zipper. She presented to the pediatric emergency department with her right upper eyelid entrapped in a zipper while getting dressed. Shewas distressed, anxious, and crying in pain. We have successfully removed the zipper using a lubricating gel, which provides local anesthesia. This case report will increase emergencyphysicians’ awareness of the technique of removing an entrapped zipper on the eyelid using a lidocaine gel.

Staphylococcus aureus coagulase serotype I to VIII isolated from clinical samples could be classified into two groups, methicillin-sensitive S. aurues (MSSA) and methicilln-resistant S. aurues (MRSA), by antibiotics susceptibility and existence of mecA which is a gene related with methicillin resistance. Coagulase serotype I, VI, and VIII were MSSA which showed different antimicrobial susceptibility. Coagluase serotype II-V and VII were MRSA in which mecA and SCCmec were detected. To analyze Sau1 restriction and modification (R-M) complex types by coagulase type and SCCmec type, sau1hsdR, sau1hsdM and sau1hsdS genes involved in Sau1 R-M complex were detected by PCR, we found five complex types such as M1, R2M2, R2M2, R2M2S1, and R2M2S2. Coagulase serotype I, VI, and VIII of MSSA were M1, R2M2 and R2M2, respectively. SCCmec type II and coagulase serotype II, SCCmec type III and coagulase serotype III, SCCmec type IV and coagulase serotype V, and SCCmec type IV and coagulase serotype IV, VII of MRSA were Sau1 R-M complex type R2M2S1, R2M2, R2M2, and R2M2S2, respectively. Taken together, correlation between Sau1 R-M complex types and coagulase or SCCmec types of S. aureus was found.

Henoch-Sh nlein Purpura(HSP) is an immuologically mediated systemic vasculitis of small blood vessels affecting predominantly the skin, gastrointestinal tract, joints, and kidneys. Clinical neurological manifestations such as headaches, behavioral changes, mental changes, seizures, and visual loss are described, but neurological complication are rare during the course of HSP. We experienced a case of an 8 year-old male with HSP who presented with seizures. Magnetic resonance imaging(MRI) showed multiple high signal intensity in both cortical and subcortical areas of frontal and parieto-occipital lobes and magnetic resonance(MR) angiogram showed stenosis of cerebral arteries, compatible with MRI and MR angiogram findings of cerebral vasculitis. We report this case with related literature.

This study was conducted to provide basic data on physiological and hematological characteristics, and organ weights of beagle dogs. A total of 237 beagle dogs were used to determine differences in physiological and hematological parameters, and organ weights depending on sex and age. The respiratory rate of both sexes tended to increase as they grew older and the female heart rate was slightly higher than that of males. Male and female body weights increased rapidly to 33 weeks old followed by a gradual increase to 41-weeks-old. The relative weight of the brain was negatively correlated with body weight, whereas the weight of reproductive organs was positively correlated with body weight. The platelet count of female dogs was slightly higher than that of males. The red blood cell, hemoglobin, and hematocrit of both sexes increased non-significantly with age. In the leukocyte differential count, the neutrophils, and eosinophils of both sexes tended to increase as they grew older, whereas basophils, lymphocytes, and monocytes decreased. In the serum biochemical profiles, alkaline phosphatase was slightly higher in males than females, while the total cholesterol of female dogs at 9-months-old was higher than that of males at the same age. Other biochemical components, including alanine aminotransferase, blood urea nitrogen, creatinine, triglyceride, and total protein increased non-significantly with age in both sexes. To conclude, we observe no significant physiological or hematological differences with sex or age, although decreasing and increasing trends were detected with some parameters. These data provide valuable reference indices of the normal physiological and hematological characteristics of beagle dogs, which should prove useful in toxicological and pharmacological studies.

OBJECTIVES: Clinical features according to the frequency of phototherapy and clinical risk factors on the number of phototherapy were investigated in premature births with gestation <35 weeks and birth weight < or =2,500 g. METHODS: The 186 infants with gestation <35 weeks and birth weight < or =2,500 g were admitted to the neonatal intensive care unit of Kosin University Gospel Hospital from March 2009 to August 2010. The 171 infants were alive and had jaundice requiring phototherapy. Phototherapy was usually started to 50-70% of the maximal bilirubin level. They were divided into two groups according to the frequency of phototherapy as single phototherapy group (group I) and multiple phototherapy group (group II). We retrospectively reviewed the medical records of all patients. RESULTS: The mean gestational age and birth weight of group I were 31.0+/-2.9 weeks and 1,596+/-485 g and those of group II were 31.1+/-2.6 weeks and 1,592+/-430 g. Compared with group I, albumin and Apgar score at 1 minute of group II were significantly higher and the day of peak bilirubin was also late. Duration of phototherapy in group II was statistically longer than that group I but duration of ventilator and aminophylline use for apnea was significantly shorter. The frequency of antibiotic use, incidence of bronchopulmonary dysplasia (BPD), and intraventricular hemorrhage (IVH) of group II were significantly lower than those of group I. CONCLUSIONS: The day of peak bilirubin was late and the frequency of antibiotic use, incidence of BPD, and IVH were low in group II. The aggressive phototherapy may be considered in premature births with jaundice.

BACKGROUND: In the diagnosis of acute myocardial infarction, measurement of CK-MB is widely used as an enzyme test, but it needs special instruments, lacks specificity in the presence of concomitant skeletal muscle injuries, and has narrow diagnostic time window. Cardiac specific troponin T-a new marker for the diagnosis of myocardial injury-is now available. Besides the quantitative assay, rapid qualitative asay is also possible with the development of rapid assay Kit. We studied about the efficacy of the Troponin T rapid assay Kit in early doagnosis of actue myocardial infarction in the emergency room. METHODS: Total Ck, Ck-MB, LDH and serum troponin T activities were determined when the patients arrived at the emergency room and at the same time Troponin T rapid assay kit test was done. Final diagnosis was made through the serial measurement of CK, CK-MB and LDH. Diagnostic efficacy of each rest was evaluated. RESULTS: Overall diagnostic sensitivity and specificity of Troponin T rapid assay kit were 0.97 and 0.91. When evaluated only with the initial results, Troponin T rapid assay kit showed sensitivity 0.87, specificity 0.97, serum troponin T 0.75, 0.92, and Ck-Mb 0.81,0.95. In one patient who was finally diagnosed as a septic shock, Ck-MB was elevated but serum troponin T was not and Troponin T rapid assay kit test showed negative result. CONCLUSION: Troponin T rapid assay kit test seems to show nearly the same sensitivity and specificity in diagnosis of acute myocardial infarction compared to CK-MB. This test can be done simply and easily in a short time. Thus, with the use of this test, morbidity, mortality and economic loss due to misdiagnosis and delay of diagnosis of myocardial infarction might be reduced.

Dapsone (4,4'-diaminodiphenylsulfone, DDS), a potent anti-inflammatory agent, is widely used in the treatment of leprosy and several chronic inflammatory skin diseases. Dapsone therapy rarely results in development of dapsone hypersensitivity syndrome, which is characterized by fever, hepatitis, generalized exfoliative dermatitis, and lymphadenopathy. Here, we describe the case of an 11-year-old Korean boy who initially presented with high fever, a morbilliform skin rash, generalized lymphadenopathy, hepatosplenomegaly, and leukopenia after 6 weeks of dapsone intake. Subsequently, he exhibited cholecystitis, gingivitis, colitis, sepsis, aseptic meningitis, disseminated intravascular coagulation, syndrome of inappropriate antidiuretic hormone secretion, pneumonia, pleural effusions, peritonitis, bronchiectatic changes, exfoliative dermatitis, and acute renal failure. After 2 months of supportive therapy, and prednisolone and antibiotic administration, most of the systemic symptoms resolved, with the exception of exfoliative dermatitis and erythema, which ameliorated over the following 4 months. Agranulocytosis, atypical lymphocytosis, aseptic meningitis, and bronchiectatic changes along with prolonged systemic symptoms with exfoliative dermatitis were the most peculiar features of the present case.
