BACKGROUND: The usage of appropriate disinfectants is essential for infection control in a hospital. Inadequate use of disinfectants is the cause of human or environmental toxicity and is a waste of cost. The objective of this study was to describe the status of the usage of disinfectants in Korean hospitals. METHOD: One hundred and eighty three hospitals of over 300 beds were investigated by a questionnaire distributed by mall. Data collection was done on November 1999. The questionnaire was made by the Association of Infection Control Nurses in Korea, based on references and protocols of the Korean Society of Nosocomial Infection Control. Numerical and percentage data were analyzed by SPSS. RESULTS: The collection rate of the questionnaire was 43.7% (80/300). Thirty five hospitals (46.7%) had an official process in selecting disinfectants in their hospitals. Regarding skin antiseptics, 10% povidone iodine and 70% alcohol were commonly used in skin preparation for intravenous catheterization or pre-operative skin disinfection, For disinfection of mucosal membranes such as mouth and periurethral area, 3% boric acid solution or 3% H202 were used. Most of the hospitals decontaminated contaminated medical instruments manually with dodecyl diamino ethyl glycine (20.8%). glutaraldehyde (15.6%). quaternary ammonium compounds (13.8%), virkon (12.3%) and sodium hypochlorites (11.7%). Glutaraldehyde and virkon were frequently used for disinfection of endoscopes. Sodium hypochlorites (48.9%) and quaternary ammonium compounds (19.8%) were the most commonly used environmental disinfectants. Some noticeable problems in disinfectants were as follows. First, for mouth care, many hospitals (41.7%) over-used boric acid, which has cumulative toxicity for humans. Second, many hospitals had an incorrect protocol of disinfecting endoscopes. Third, for environmental decontamination and instrument cleaning, some hospitals used high level disinfectants such as glutaraldehyde, which is too costly and provides unnecessary safety problems. Fourth, after patient discharge, many hospitals did not use disinfectants at all. Considering the specific Korean medical environment of high incidence of multi-drug resistant microorganisms, use of disinfectants for discharged environments may be warranted. CONCLUSION: This study included only hospitals of over 300 beds, which has a limitation in representing the status of disinfectants usage in a country. However, significant problems from misunderstanding the basic principles of disinfectants and misusages of disinfectants were observed in this investigation. These observations will provide useful information for designing a guideline for the appropriate uses and for efficient education of disinfectants, and also for planning a national control program for proper disinfectants usage in this country.

OBJECTIVE: This study was designed to evaluate the effect of nasogastric tube on swallowing function in stroke patients with dysphagia. METHOD: Twelve stroke patients with dysphagia were included in this study. We evaluated the Functional Dysphagia Scale using videofluoroscopic swallowing study. Swallowing tasks were composed of swallowing 5 cc of thick food and same volume of fluid on nasogastric tube insertion state and then nasogastric tube removal state. RESULTS: As the result of measuring oral phase score before and after removing nasogastric tube, all of 12 patients showed no significant difference. There was statistically significant increase in score of residue in piriform sinuses on thick food swallowing after removing nasogastric tube (p<0.05). After removing nasogastric tube, aspiration was decreased on fluid swallowing in cases of 2 patients, while aspiration on thick food swallowing was increased in cases of 2 patients, compared with nasogastic tube insertion state. CONCLUSION: As the result of this study, the stroke patients with dysphagia on nasogastric tube were increased on fluid aspiration due to rapid descending and inhibition of epiglottic closure compared with the removal state of nasogastric tube. And there was significant increased in scores of residue in piriform sinuses on thick food swallowing and aspiration pneumonia after removing nasogastric tube.

Neurofibromatosis is a complex hereditary disease involving many organs and systems. The incidence in pregnancy is less frequent and has been reported as 1/5000 to 1/18500 deliveries. Therefore, little is known about the interactions between neurofibromatosis and pregnancy. A survey of relevant literature suggests that patients with NF have an increased risk of perinatal complications (pregnancy induced hypertension, IUGR, preterm labor, abortion, stillbirth, high cesarean section rate) and maternal disease aggravation (rupture of an aneurysm, sarcomatous degeneration of neurofibroma, activation of pheochromocytoma). Refined ultrasound, flow studies and fetal monitoring allow us to provide improved pregnancy care for neurofibromatosis. However, It should be remembered that even now, neurofibromatosis places pregnant women and their fetuses in a high risk group with the potential to develop life threatening complications. We report a case of vertebral artery aneurysm and preeclampsia complicating a pregnancy with neurofibromatosis."

If orthodontists and restorative dentists establish the interdisciplinary approach to esthetic dentistry, the esthetic and functional outcome of their combined efforts will be greatly enhanced. This article describes satisfying esthetic results obtained by the distribution of space for restoration by orthodontic treatment and porcelain laminate veneers in uneven space between maxillary anterior teeth. It is proposed that the use of orthodontic treatment for re-distribution of the space and the use of porcelain laminate veneers to alter crown anatomy provide maximum esthetic and functional correction for patients with irregular interdental spacing.

OBJECTIVES: Traditional nonparametric efficiency analysis was based on the relationship between the quantitative input and output measures. This study performed nonparametric efficiency analysis, which uses the results of dental hospital accreditation with quantitative output measures. METHODS: Data came from 35 hospitals between 2008 and 2010 that participated in the demonstration projects of dental hospital accreditation. The study employed two-stage double bootstrapping (TSDB) method to overcome the shortcomings and biased results of the traditional Data Envelope Analysis (DEA). Input measures included staffs, dental hygienists, other chair-side assistants, and administrative personnel, as well as dental equipment (dental chairs). Production measures were total revenues and the number of patients that visited the participating hospitals. We considered the environmental variables, which would affect the efficiency score of dental hospitals, dental hospital types, accreditation scores, and patients' satisfaction scores. RESULTS: There was a large split between the traditional DEA scores and TSDB scores. A total of 22 out of 35 hospitals had perfect efficiency in the traditional method, but none of those showed 100% efficiency in the TSDB. Overall efficiency score was the highest in the dental facility of general hospitals (71% mean efficiency), and dental teaching hospitals were the lowest (55% mean efficiency score). The factors that affected the efficiency of dental hospitals were the types of the dental hospital and the accreditation score. CONCLUSIONS: Traditional DEA scores had biased estimates and tended to be higher. The study found that organizational efforts for improving service qualities and patient safety would affect the efficiency, as well as the accreditation results.
