OBJECTIVES: Continuous positive airway pressure (CPAP) is effective in the treatment of obstructive sleep apnea syndrome (OSAS), but the major limitation of CPAP may be poor compliance. The aims of the study were to investigate the compliance and side effects of CPAP, and to evaluate the efficacy of CPAP in patients with OSAS. METHODS: This study enrolled 106 patients with OSAS who took the CPAP treatment. The severity of daytime sleepiness was measured using Epworth Sleepiness Scale (ESS), and sleep quality and depressive symptoms were assessed by Pittsburgh Sleep Quality Index (PSQI) and Beck Depression Inventory (BDI), respectively. RESULTS: During 29 months of the study period, 41.5% of patients were using CPAP and 38.7% of patients stopped using it. Compared to non-compliant patients, compliant patients had a higher PSQI score and obstructive apnea index. Among non-compliant patients, 51.2% of them stopped using CPAP within 1months. 85.7% of non-compliant patients were discomforted by the CPAP, but much more nasopharyngeal symptoms were reported in the compliant group. ESS (p<0.01), PSQI (p<0.01) and BMI (p<0.01) were reduced significantly after CPAP treatment but not BDI (p=0.86). CONCLUSIONS: We concluded that CPAP can reduce the daytime sleepiness, nocturnal sleep disturbance, and body mass index. To increase the compliance of CPAP, we suggested that some education and support is needed at the early stage of the CPAP treatment.

PURPOSE: To evaluate the value of fast field echo(FE) technique in accesing temporOmandibular joint(TMJ) dynamics. MATERIALS AND METHODS: A series of 120 TMJ MRI examinations of 60 symptomatic patients was performed. The fast FE technique was used to provide dynamic images of the TMJs in various phase of mouth opening with a step-bite-block. RESULTS: Among 120 cases, there were 30 cases which were normal, 21 cases of anterior displacement with reduction, 66 cases of anterior displacement without reduction, 11 cases of deformity of menisci, 23 cases of bony deformity, and 3 cases of medial displacement. The menisci and condyles were clearly delineated and the motions of the menisci during jaw opening were well evaluated in both normal and pathologic conditions. CONCLUSION: The dynamic TMJ MRI scan using fast FE technique permits both fast scanning and study of joint dynamics as well as TMJ anatomy.

PURPOSE: This study was done to examine the awareness and management practice of operating room nurses, to prevent nosocomial infection, to identify problems and to propose solutions. METHOD: The research tools used were the hospital infection control guideline and a modified version of the measurment tools used in the study of Cho (1998). The questionnaire consisted of questions on hand washing, personal hygiene and clothes control, cleaning and environment control, sterilizing supplies and disposal of contaminated materials. The collected data were analysed with the SPSS program. RESULTS: The mean score for domain-specific awareness of nosocomial infection control was 4.81 out of a possible 5 points. The highest score was for sterilizing supplies and disposal of contaminated materials. The mean score for domain-specific practices of nosocomial infection control was 4.40, out of a possible 5 points. Sterilizing supplies and disposal of contaminated materials had the highest scores. The mean score for awareness in all domains was higher than mean score for practice. Among the general characteristics of the nurses, high awareness was found only in the provision of infection control guidelines and it had shown statistically significant difference. Examination of relation of general characteristics to practice showed that for age, career, the provision of infection control guidelines, and experience in infection control education there were statistically significant differences in the scores. For the relation between awareness of nosocomial infection control and practice, positive correlation was found in all domains, thus high awareness leads to high practice. CONCLUSION: Considering the result of this research, plans are needed that promote virtual practice of hospital infection control.

BACKGROUND: Laryngoscopy and tracheal intubation for general anesthesia are potent stimuli to the cardiovascular system due to sympathetic stimulation. The aim of this study was to compare the hemodynamic responses with different administration routes of lidocaine on blood pressure and heart rate changes associated with tracheal intubation. METHODS: Sixty patients were randomly assigned to spray group (Group 1, n=20) received 10% lidocaine 1.5 mg/kg spray to intratracheally immediately before tracheal intubation, IV group (Group 2, n=20) received 2% lidocaine 1.5 mg/kg intravenously before 90 sec tracheal intubation and control group (Group 3, n=20). Anesthesia was induced with thiopental 5 mg/kg IV, vecuronium 0.1 mg/kg and 50% N2O-O2- 2vol % enflurane. After 5 minutes, tracheal intubation was performed. Mean arterial pressure and heart rate were measured at preintubation and immediately postintubation, 1, 3, 5 mins after tracheal intubation. RESULTS:The differences of mean arterial pressure which were measured at preintubation and immediately postintubation and 1 minute after intubation in group 1 were significantly lower than those in other group (p<0.05). The differences of heart rate which measured at preintubation and 1 minute after intubation were lower than those in group 3 (p<0.05). CONCLUSIONS: For the suppression of sympathetic stimulation following tracheal intubation, 10% lidocaine spray to the laryngotrachea is an effective method to suppress cardiovascular response.

It is hard to advice for fitting contact lens in the case of monocular lens extraction in rural area because of exposure to dust laden air and elderly people in most cases. Questionares for comfortability, Side effects and the method of visual correction were obtained in 200 cases of cataract operation in rural area. Most of the advanced age group replyed that the unsatisfactory and difficulty for fitting contact lens, therefore it is desirable method to obtain good adaptation and binocualr vision with P-A (Phakic and Aphakic) spectacles by intensive training.

BACKGROUND: Cine MR imaging has been found to bo a non-invasive technique in evaluation cardiac anatomy and cardiovascular function in a variety of cardiac diseases. The capability of this technique for quantatively estimating the severity of regurgitation has not been tested in newborns. The purpose of this study is to compare the degees of tricuspid regurgitation by echorcardiography with those by cine MRI, and verify the utility of MRi in evaluating tricuspid regurgitation. METHODS: Fifty-one newborns with tricuspid regurgitation were evaluated on the same day by echocardiography and cine MRI. Area and regurgitant fraction of area were estimated at four chamber view by two techniques. RESULTS: The area of tricuspid regurgitation was similar by two techniques. The correlation for the area(r=0.66, p<0.025) and the regurgitant area fraction(r=0.647, p<0.025) of tricuspid regurgitation obained by cine MRI with echocardiographic data was good. CONCLUSION: Cine MR imaging can provide quantative data estimating for evaluation of tricuspid regurgitation in newborns.
