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.

Myotonia dystrophica(Synonym: Myotonia atrophica, Dystrophia myotonia, Steinert's disease) is a autosomal dominant hereditary multisystemic disorder involving several organs besides skeletal muscle, and commonly called with myotonia congenita, paramyotonia congenita as myotonia. Although most cases are of adult onset, where a mother has the disease, neonatal dystrophia myotonia can occur in her offspring. The main feature is a steadily progressive muscle dystrophy, complicated by myotonia, which is a failure of muscles to relax normally after a forceful contraction. Steinert in 1909 was the first to report the finding of atrophic testes and baldness in patients with myotonia dystrophica, and the other clinical feature of myotonia dystrophica were reported by many authors after that time. We are reporting a case of myotonia dystrophica, which showing familial history with brief review of literature.

PURPOSE: Although, urgent intubation is commonly thought to be associated with a high complication rate and poor outcome, early intubation before deterioration and airway compromise is recommended. We designed a study to evaluate the factors associated with the mortality rate of non-traumatic patients intubated in an emergency department (ED). METHODS: Data were retrieved retrospectively from the patient registry for patients >15-years-of-age who had received ED intubation from June 1, 2007 to June 30, 2008. Patient demographic data, clinical and laboratory findings, vital signs, and specific data concerning intubation procedures were included. Acute physiologic and chronic health evaluation (APACHE) II scores were calculated for every patient. RESULTS: From the initial 241 non-traumatic ED intubated patients, 115 were excluded for out-of-hospital arrests, inadequate data, and undetected esophageal intubation. The remaining 126 patients were enrolled in this study. Sixty (47.6%) patients died during hospital treatment. From multivariate logistic regression analysis, respiratory rate and the time from ED arrival to intubation were associated with increased mortality, which showed an odds ratio (95% Cl) of 1.081 (1.026~1.141) and 1.428 (1.066~1.91), respectively. CONCLUSION: The increase in respiratory rate and the time interval of intubation from ED arrival to intubation in non-traumatic patients are related to increased in-hospital mortality.

Purpose: To report a case of subacute methicillin-resistant coagulase-negative Staphylococcus hominis endophthalmitis after re-operation for penetrating keratoplasty in a patient who had a penetrating keratoplasty rejection.Case summary: A 74-year-old man with underlying diabetes and hypertension who underwent bilateral penetrating keratoplasty at another hospital underwent penetrating keratoplasty reoperation due to corneal transplant rejection in the right eye. He had a history of end-stage glaucoma in the right eye and the visual acuity was finger counting at 30 cm. About 25 days postoperatively, the corneal epithelial defect was first found. Treatment based on suspicion of herpes simplex virus infection did not result in improvement and endophthalmitis was suspected in the right eye about 35 days after surgery. Anterior chamber irrigation, pars planar vitrectomy, and intravitreal antibiotic injection were performed. Culture revealed methicillin-resistant coagulase negative Staphylococcus hominis. After 2 months of treatment, the anterior chamber and vitreous inflammation decreased and best corrected visual acuity in the right eye recovered to 0.06. Conclusions Subacute endophthalmitis caused by methicillin-resistant coagulase-negative Staphylococcus may occur after penetrating keratoplasty. Transplant failure due to infection can be avoided with vitrectomy and antibiotic treatment at the right time.

This study was conducted to fine out the preventive effects of chitosan and chitosan oligomer on the disorders of hepatic functions and lipid metabolism induced by 2, 3, 7, 8-tetrachlorodibenzo-p-dioxin (TCDD), using adult male rats (SD) for four weeks. Rats were fed chitosan (4%) or chitosan oligomer (4%) diets respectively before 3weeks of TCDD treatment (50 ug/kg BW) by intraperitoneal injection and then continually supplied these diets for one week until being sacrificed. The elevation of serum total and LDL cholesterol levels induced by TCDD treatment was significantly reduced in the rats fed chitosan diets. The increment of liver triglyceride levels caused by TCDD treatment was tended to suppress in all rats fed chitosan and chitosan oligomer diets. Fecal total lipid and cholesterol excretion were high levels in the rats fed chitosan diets. The hepatic cytosolic catalase activities significantly decreased by TCDD treatment appeared recovering trend by chitosan diets. In hepatic microsomal cytochrome p-450, NADPH cytochrome p-450 reductase, ethoxycoumarin-o-deethylase (ECOD) and benzphetamin N-demethylase (BPND), chitosan than chitosan oligomer diets apparently decreased the increasing levels by TCDD treatment. In histochemical observation, the fat droplets and apoptosis of hepatocytes by TCDD treatment were markedly alleviated by chitosan and chitosan oligomer diets. These results indicate that chitosan, more than chitosan oligomer can exert preventive effects on some disorders of hepatic functions and lipids accumulation by TCDD.

Congenital pulmonary lymphangiectasia (CPL) is a rare lymphatic pulmonary abnormality. CPL with respiratory distress has a poor prognosis, and is frequently fatal in neonates. We report a case of pneumonectomy for CPL in a newborn. An infant girl, born at 39 weeks' after an uncomplicated pregnancy, exhibited respiratory distress 1 hr after birth, which necessitated intubation and aggressive ventilator care. Right pneumonectomy was performed after her symptoms worsened. Histologic examination indicated CPL. She is currently 12 months old and developing normally. Pneumonectomy can be considered for treating respiratory symptoms for improving chances of survival in cases with unilateral CPL.

PURPOSE: We evaluated three blood glucose self-monitoring for measuring whole blood glucose levels in preterm and low-birth-weight infants. METHODS: Between December 1, 2012 and March 31, 2013, 230 blood samples were collected from 50 newborns, who weighed, < or =2,300 g or were < or =36 weeks old, in the the neonatal intensive care unit of Eulji University Hospital. Three blood glucose self-monitoring (A: Precision Pcx, Abbott; B: One-Touch Verio, Johnson & Johnson; C: LifeScan SureStep Flexx, Johnson & Johnson) were used for the blood glucose measurements. The results were compared to those obtained using laboratory equipment (D: Advia chemical analyzer, Siemens Healthcare Diagnostics Inc.). RESULTS: The correlation coefficients between laboratory equipment and the three blood glucose self-monitoring (A, B, and C) were found to be 0.888, 0.884, and 0.900, respectively. For glucose levels< or =60 mg/dL, the correlation coefficients were 0.674, 0.687, and 0.679, respectively. For glucose levels>60 mg/dL, the correlation coefficients were 0.822, 0.819, and 0.839, respectively. All correlation coefficients were statistically significant. And the values from the blood glucose self-monitoring were not significantly different from the value of the laboratory equipment , after correcting for each device's average value (P>0.05). When using laboratory equipment (blood glucose < or =60 mg/dL), each device had a sensitivity of 0.458, 0.604, and 0.688 and a specificity of 0.995, 0.989, and 0.989, respectively. CONCLUSION: Significant difference is not found between three blood glucose self-monitoring and laboratory equipment. But correlation between the measured values from blood glucose self-monitoring and laboratory equipment is lower in preterm or low-birth-weight infants than adults.
