The provision of adequate soft tissue cover for a complex hand and forearm wound-dirty, infected and exposed bone can be a challenging problem. Conventionally, a distant flap or free flap have been used, but these have been associated with several problems such as joint stiffness, risk of microsurgical procedures, negligible donor site morbidity, prolonged operation time and economic restriction. As well, fasciocutaneous flap has been the limitation of infection control. In these situations, the ipsilateral muscle flap provides the ideal cover with its rich blood supply and single operative field. Previously described by Lendrum(1980), by Lae et al.(1981), and later by McGeorge(1991), the brachioradilis muscle is the most superficial muscle on the radial side of the forearm. Its flap is based on the radial artery and venae comitantes. From August 1996 to October 1997, we performed branchioradialis muscle flap in seven patients. Despite the sacrifice of the major hand artery, brachioradialis muscle flap has many advantages including the reliability of flap survival, easy dissection, early mobilization and absence of functional and aesthetic problems at the donor site. It is a relatively simple and rapid method for resurfacing soft tissue defect in the hand and forearm. We obtained satisfactory and reliable results.

The purpose of this study is to investigate the effect of job stress and social support on the organizational effectiveness of hospital employees and to examine the role of social support in the experience of job stress among the employees. Previous studies have yielded mixed results regarding the role of social support. Some studies provide supporting evidence for the buffering effect of social support, while others do not. Still others report findings about reverse buffering effects. These inconsistent findings are, in part, accounted for by methodological problems such as poor measurement, small sample size, and the existence of high multicollinearity. To examine more rigorously the role of social support in relation to the negative effects of job stress, this study was carefully designed to overcome methodolgical shortcomings found in the past research. In addition, unlike the previous studies, which were concerned mostly with health-related variables as consequences of job stress, in this study, three work-related variables (job satisfaction, organizational commitment, and intent to stay) which had close relationships with organizational effectiveness were examined as output variables. The sample used in this study consisted of 353 employees from a university hospital in the suburbs of seoul. Data were collected with self-administered questionnaires and analyzed using canonical analysis and hierarchical regression analysis. The results of this study indicate that; (l) job stress has negative main effects on job satisfaction, organizational commitment, and intent to stay; (2) social support has positive main effects on the same three output variables, (3) social support does not moderate the harmful effects of job stress on the three outcome variables, and (4) the three-way interaction effects of (social support * job stress * gender) and of (social support * job stress * education) are not supported The implications of these findings for the management of human resources are discussed.

Respiratory syncytial virus (RSV) and Influenza virus are the most common pathogen for causing severe upper respiratory infection in all age groups. A multiplex reverse transcription polymerase chain reaction (RT-PCR) has been developed to detect and subtype influenza A (H3N2 and H1N1), B virus and RSV simultaneously in one tube reaction. Amplification with primers derived from conserved sequences within the nucleocapsid for RSV and hemagglutinin subunit for Influenza A (H3N2 and H1N1) and B viruses yielded a 384 bp, a 300 bp, a 236 bp and a 151 bp, respectively. Assay specificity was confirmed by pulse field gel electrophoresis and autosequencing method. Assay sensitivity was 3 PFU/ml of RSV, 22 PFU/ml, 45 PFU/ml of Influenza type A (H3N2 and H1N1) and 6.6 PFU/ml of Influenza B virus by plaque assay. A rapid and sensitive detection method of a one-tube with multiplex RT-PCR capable of identifying more than one viral template as well as synchronizing reverse transcription and PCR had the potential to produce considerable savings of time and cost effectiveness in the diagnostic laboratory.

PURPOSES: We analysed the five-year outcomes and associated complications of transscleral diode laser photocoagulation (TSDLP), used to treat acute proliferative retinopathy of prematurity (ROP), to evaluate the efficacy and safety of this therapy. METHODS: We performed a retrospective analysis of the records of 163 eyes of 82 infants with acute ROP, who were treated with TSDLP by a single surgeon. Follow-up periods ranged from 15 to 278 weeks. RESULTS: The outcome was favorable in 158 eyes (96.9%) and unfavorable in 5 eyes (3.1%) of the 163 eyes that were treated. Vitreous hemorrhage was found to be an indicator of poor prognosis. Of the complications noted, symblepharon was observed in three eyes, hyphema was observed in four eyes, and a complicated cataract was observed in one eye. CONCLUSIONS: The results suggest that TSDLP is a safe and effective in the treatment of ROP. Vitreous hemorrhage should be regarded as a sign of poor prognosis.

Intraocular pressures (IOP)were measured following Neodymium (Nd): YAG laser posterior capsulotomy in 51 pseudophakic eyes which had been treated with phacoemulsification and intraocular lens in the bag.Group 1 was no medical treated, group 2 was treated with 0.5%apraclonidine preoperatively, group 3 was treated with fluorometholone postoperatively, and group 4 was treated with 0.5%apraclonidine preoperatively and with fluorometholone postoperatively.IOP was measured preoperatively and 1, 3, 24 hours and 1 week postoperatively.Four eyes (7.8%)had greater than 5 mmHg elevation of IOP (1 eye in group 1, 3 eyes in group 3)and all of them decreased IOP to normal level within 3 hours.In summary, there was no or little IOP elevation without any medical treatment in eyes which had been treated with phacoemulsification and intraocular lens in the bag and had intact posterior lens capsule.

PURPOSE: To compare the clinical outcomes between patients undergoing argon laser trabeculoplasty (ALT) and those undergoing selective laser trabeculoplasty (SLT). METHODS: Sixty-one eyes of 61 patients with primary open-angle glaucoma who were treated with more than 1 kind of antiglaucoma medication eye drop were enrolled in this study. Thirty-five eyes of 35 patients were treated with argon laser trabeculoplasty (ALT). Twenty-six eyes of 26 patients were treated with selective laser trabeculoplasty (SLT). The mean IOP at 1, 3, 6, and 12 months and the success rate of treatment at the 12-month follow-up period were evaluated in all patients. RESULTS: At 12 months postoperative, the ALT group had a mean IOP of 16.53+/-2.58 mmHg with a mean IOP reduction of 35.27%, while the SLT group had a mean IOP of 18.40+/-5.61 mmHg with a mean IOP reduction of 17.37%. The success rates of treatment defined as definition 1 were 62.85% in ALT and 62.50% in SLT, and the success rates defined as definition 2 were 51.42% in ALT and 46.15% in SLT. CONCLUSIONS: There were no significant differences in the IOP lowering effect or success rates between the ALT and SLT patients at 12 months postoperatively.
