Eosinophilic granuloma of bone well-documented in the literature. This lytic bone disease most commonly occurs in children, but a fraction of the cases does occurs in adult. When the disease occurs in adults, the bone most often affected include the skull, ribs, mandible, clavicle, pelvis, and long bone of the extremities. We report the case of a 31-year old woman with isolated eosinophilic granuloma of the thoracic spine. She had a 1-month history of progressive back pain that radiated to the right anterior chest. Authors performed resection of vertebral body lesion and soft tissue lesion and anterior fusion from T7 to T9. Immunochemical staining showed a positive S100 protein stain. EM demonstrated characteristic Birbeck granule. Postoperatively, the patient underwent a 5-day course of RT to the T6-T10 spine with 200cGY fractions (total dose 1000cGY). Postoperatively, the patient's back and chest pain had disappeared. There is no evidence of local recurrence or distant metastasis at 18 months follow-up. Though rare, eosinophilic granuloma of the adult spine could be considered in the differential diagnosis of osteolytic lesions.

Open reduction and internal fixation of the displaced fractures of the acetabulum represents one of the greatest challenge in fracture surgery. The purpose of our study is to report the results of operative treatment and establish the guideline for the operative treatment of the displaced acetabular fractures with the analysis of the clinical and radiological results. This retrospective study reports the results of 21 fractures in 21 patients(19 male and 3 female) treated by open reduction and internal fixation from January 1990 to July 1994. The patients were followed up more than 1 year and mean length of follow-up was 2.3 years. According to Letournel's classification, we had 9 elementary fractures(42.8%) and 12 associated fractures(57.2%). Among the elementary fractures, the posterior wall fracture was the most common type(7 cases, 33.3%) and the transverse-posterior wall fracture was the most common type among associated fractures(4 cases, 19.0%). Surgical approaches were 14 Kocher-Langenbeck, 6 Ilioinguinal and 1 extended iliofemoral. Indirect reduction and specially designed reduction method using C-arm and radiolucent operating table were also helpful to achieve satisfactory reduction. Overall quality of clinical results was graded according to the D'Aubigne and Postel rating score. Satisfactory reduction was gained in 16 cases(76.1%). Unsatisfactory reduction was gained in 5 cases(23.8%). Among the cases within category of satisfactory reduction, there were 7 excellent and 8 good clinical results. But among unsatisfactorily reduced 5 cases, there were 2 good clinical results. It seems that the satisfactory operative reduction of the fracture is the factor that correlates with a satisfactory clinical result. There were complications such as 3 secondary osteoarthritis(14.2%), 3 wound infection(14.2%, 2 superficial and 1 deep), 2 iatrogenic nerve palsy(9.5%, 1 sciatic and 1 obturator nerve) and 1 intrapelvic protrusion acetabuli(4.7%) and no postoperative ectopic ossification.

BACKGROUND: Cladosporium spp. are dematiaceous fungi that are commonly isolated from indoor and outdoor environments, including hospital air. This fungus is rarely pathogenic to humans, but has been reported to cause infections of the skin and toenails, as well as sinusitis and pulmonary infections. The monitoring of culture results was conducted to identify the outbreak of an unknown black fungal infection between January and March 2006 in a University hospital, and infection control activity was performed to identify the cause of the outbreak. METHODS: An epidemiological investigation of 22 patients with infections caused by an unknown black fungus was conducted. Microscopic examination and molecular analysis on the internal transcript spacer (ITS) region was performed to identify the black fungus. To detect the source of contamination, a culture of environmental specimens was performed, and then, disinfection of the laboratory was implemented. RESULTS: The patients with black fungi belonged to various departments and wards. No symptoms of fungal infection were recognized on the basis of the survey. The black fungus was identified as Cladosporium spp. on the basis of morphological features and ITS region sequencing. Culturing of environmental specimens was performed in the laboratory. Black fungi were isolated from a specimen from a rack and had the same morphological features with Cladosporium spp. from clinical specimens. After the rack was autoclaved, Cladosporium spp. from clinical specimens was no longer isolated. CONCLUSION: Epidemiological investigation, microscopic examination, and molecular analysis revealed that the sudden increase in the isolation rate of Cladosporium spp. from clinical specimens was the result of a pseudo-outbreak caused by the contamination of a rack. To our knowledge, this is the first report of a pseudo-outbreak of Cladosporium spp. Continuous monitoring of culture results is important to avoid unnecessary labor for nosocomial infection control.

Neonatal intensive care units have been present in Korea since the past 30 years, after their introduction in the 1980s. Neonatal and infant mortality rates have remarkably reduced with improvement in the survival rates of high-risk infants such as very-low-birth-weight infants and early preterm infants, as a result of recent advance in therapeutic modalities, equipment, and support systems. It may be useful to summarize the statistical changes that have occurred over the past 30 years in neonatal outcomes with respect to neonatal epidemiology. The present review aims to summarize these outcomes with respect to neonatal epidemiology, such as analysis of the number of births; crude birth rate; incidence of preterm-birth, multiple-birth, and low-birth-weight infants; neonatal and infant mortality; survival rate and morbidity of very-low-birth-weight-infants; and changes in neonatal causes of death. This review is intended to contribute to further development in neonatal intensive care as well as normal nursery care by summarizing the the historical neonatal epidemiologic data for the last 3 decades in Korea.

PURPOSE: Pulmonary surfactants for preterm infants contain mostly animal-derived surfactant proteins (SPs), which are essential for lowering surface tension. We prepared artificial pulmonary surfactants using synthetic human SP analogs and performed in vitro and in vivo experiments. MATERIALS AND METHODS: We synthesized peptide analogues that resemble human SP-B (RMLPQLVCRLVLRCSMD) and SP-C (CPVHLKRLLLLLLLLLLLLLLLL). Dipalmitoylphosphatidylcholine (DPPC), phosphatidylglycerol (PG), and palmitic acid (PA) were added and mixed in lyophilized to render powdered surfactant. Synsurf-1 was composed of DPPC:PG:PA:SP-B (75:25:10:3, w/w); Synsurf-2 was composed of DPPC:PG:PA:SP-C (75:25:10:3, w/w); and Synsurf-3 was composed of DPPC:PG:PA:SP-B:SP-C (75:25:10:3:3, w/w). We performed in vitro study to compare the physical characteristics using pulsating bubble surfactometer and modified Wilhelmy balance test. Surface spreading and adsorption test of the surfactant preparations were measured. In vivo test was performed using term and preterm rabbit pups. Pressure-volume curves were generated during the deflation phase. Histologic findings were examined. RESULTS: Pulsating bubble surfactometer readings revealed following minimum and maximum surface tension (mN/m) at 5 minutes: Surfacten® (5.5±0.4, 32.8±1.6), Synsurf-1 (16.7±0.6, 28.7±1.5), Synsurf-2 (7.9±1.0, 33.1±1.6), and Synsurf-3 (7.1±0.8, 34.5±1.0). Surface spreading rates were as follows: Surfacten® (27 mN/m), Synsurf-1 (43 mN/m), Synsurf-2 (27 mN/m), and Synsurf-3 (27 mN/m). Surface adsorption rate results were as follows: Surfacten® (28 mN/m), Synsurf-1 (35 mN/m), Synsurf-2 (29 mN/m), and Synsurf-3 (27 mN/m). The deflation curves were best for Synsurf-3; those for Synsurf-2 were better than those for Surfacten®. Synsurf-1 was the worst surfactant preparation. Microscopic examination showed the largest aerated area of the alveoli in the Synsurf-3 group, followed by Synsurf-1 and Surfacten®; Synsurf-2 was the smallest. CONCLUSION: Synsurf-3 containing both SP-B and SP-C synthetic analogs showed comparable and better efficacy than commercially used Surfacten® in lowering surface tension, pressure-volume curves, and tissue aerated area of the alveoli.

Of the many potential source of free radial generation, the enzyme xanthine oxidase has been shown to be important in ischemia in non-cerebral tissues. Oxygen-derived free radicals have been implicated in various pathological conditions including ischemia. Xanthine oxidase serve as a source of oxidizing agents such as superoxide radical and hydrogen peroxide. It is investigated that the effect of a specific xanthine oxidase inhibitor, allopurinol, on infarct size in a model of continuous partial cerebral ischemia in rats. Infarct volume was measured by triphenyl tetrazolium chloride staining of brains removed 24 hours after middle cerebral arterial occlusion. Cortical tissue was more effectively protected than basal tissue, especially in allopurinol pretreated group. On histological examinations, hemispheric swelling, PMN cell infiltration and endothelial damage were noted irrespective of allopurinol treatment. It was speculated that free radicals are important in infarction secondary to partial continuous cerebral ischemia and that xanthine oxidase may by the primary source of these radicals.
