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: The effect of 0.2% cyclosporin A (CsA) as an adjuvant therapy after glaucoma-filtering surgery was the focus of this study. METHODS: A posterior lip sclerotomy was performed in 16 eyes of 8 rabbits, and 0.2% CsA was administered into the right eyes. The left eyes served as controls. The intraocular pressure (IOP) was measured 1, 3, 5, 7, 14, and 28 days after surgery. Hematoxylin-eosin (HE) and anti-bromodeoxyuridine (BrdU) immunocytochemical staining were performed at 1, 2, 4, and 8 weeks. RESULTS: The IOP at 7 and 14 days after surgery was lower in the 0.2% CsA group and statistically significant (P=0.047, P=0.48; respectively). HE staining did not show any difference between experimental and control eyes, but anti-BrdU staining showed a lower number of positive cells in the experimental eyes at 1 week. The fibroblast proliferation rate was significantly lower 1 week after surgery in the 0.2% CsA group (P=0.003). CONCLUSIONS: An effect of 0.2% CsA on early wound healing was observed. The data suggest that a low concentration of CsA can be useful when employed as adjuvant therapy in glaucoma filtering surgery.

Magnetic resonance (MR) imaging of thirteen patients with tuberous sclerosis were reviewed. Seven patients underwent computed tomography (CT). The characteristic MR finding of tuberous sclerosis was those of subependymal nodules which were best seen on short repetition time (TR) spin-echo images. Hypointensities within the nodules consistent with calcification were most evident on long TR images. Contrast enhancing lesions, indicative subependymal giant cell astrocytoma, occurred in four cases. Cortical tubers (n=11) and white matter lesions(n=8) exhibited long T1 and T2 relaxation characteristics although reversed pattern was noted in one newborn patients. Cortical tubers and white matter lesions had more irregular shapes in early childhood patients. MR imaging is the sensitive method in detection of gyral tubers and white matter lesions and also valuable in detecting giant all astrocytoma.

Commonly, the lateral canthus is located higher than medial canthus and many people are often shown short lateral palpebral fissure. This seemed to be shown as wild, anxious, and pierced eye. Many surgeons have made desperate efforts to improve this by anchoring lateral canthus to lower part of orbital bone. But, authors would like to show the two-third portion of the lateral lower eyelid by anchoring to capsulopalpebral fascia via transconjunctival approach. Authors performed this operation since 2009 and first named it by "Nun-Mit-Teuim" in Korean. Key of this operation is that anchoring of the lower tarsus and capsulopalpebral fascia via transconjunctival approach without resection of skin. It is not necessary to remove a redundant conjunctiva. Commonly, the lateral canthoplasty is performed simultaneously to descend a lower eyelid easily. After the operation, it can be observed that the lower eyelid lift up a little bit for 1~2 weeks and redundant conjunctiva will be constricted in several months. The operation is defined as anchoring the lower tarsus to capsulopalpebral fascia. The limit of the operation is it cannot change the position of the lateral canthus. Over-lowering the lower eyelid to increase palpebral fissure, results in scleral show and unfavorable line. Thus, it is important that surgeons should remind the purpose and limitation of this operation.

Eisenmenger's syndrome is defined as pulmonary hypertension with right-to-left or bidirectional shunting of blood through an intracardiac or aorto-pulmonary commumication. It can occur with complex congenital cardiac malformations, such as septal defect and patent ductus arteriosus. Parturients with Eisenmenger's syndrome are at high risk for peripartum morbidity and mortality. We experienced a case of parturient for cesarean section with Eisenmenger's syndrome and performed epidural anesthesia with fractionated doses of 2% lidocaine and fentanyl. The sensory block reached to T10 level and blood pressure was maintained with intravenous phenylephrine. After baby out, sudden hypotension with severe bradycardia developed and arterial oxygen saturation dropped. Immediate intubation and resuscitation was done, but cardiac rhythm disturbance, hypoxemia, and acidosis did not corrected. Cardiac standstill developed and stopped resuscitation. The neonate's Apgar score was 7 and he was transferred to pediatric ICU.

The aim of this study is to review the protective effect of a bicycle helmet on each facial location systematically. PubMed was searched for articles published before December 12, 2014. The data were summarized, and the odds ratio (OR) between the locations of facial injury was calculated. A statistical analysis was performed with Review Manager (The Nordic Cochrane Centre). Bicycle helmets protect the upper and middle face from serious facial injury but do not protect the lower face. Non-wearers had significantly increased risks of upper facial injury (OR, 2.07; P<0.001) and of middle facial injury (OR, 1.97; P<0.001) as compared to helmet users. In the case of lower facial injury, however, only a slightly increased risk (OR, 1.42; 95% confidence interval (CI), 0.67-3.00, P=0.36) was observed. The abovementioned results can be attributed to the fact that a helmet covers the head and forehead but cannot cover the lower face. However, helmets having a chin cap might decrease the risk of lower facial injury.
