Purpose:
To assess the clinical outcomes of scleral buckling (SB) without subretinal fluid drainage (SRFD) on primary rhegmatogenous retinal detachment (RRD).
Methods:
The medical records of patients with RRD treated via SB without SRFD from March 2009 to Feb 2018 were retrospectively reviewed. Cases with histories of previous intraocular surgery (except cataract removal) were excluded. The primary and final surgical success rates were the main outcome measures. Pre- and post-operative visual acuity and intraocular pressure (IOP), factors that might affect the surgical success rate, secondary operative procedures, re-operation rates, and complications were analyzed.
Results:
A total of 66 eyes of 66 patients were included. The mean patient age was 38.9 ± 18.6 years and the mean symptom duration 19.23 ± 25.14 days. The retinae were reattached after single surgeries on 57 eyes (success rate 86.36%); the final success rate was 100% after a second operation (when necessary). Of the nine eyes requiring additional surgery, seven required vitrectomy and two vitrectomy combined with buckle revision. The mean preoperative logMAR visual acuity of 0.578 ± 0.647 improved to 0.518 ± 0.512 at 1 month after surgery (p < 0.001) and to 0.262 ± 0.372 at the last follow-up visit (p < 0.001). The postoperative IOP was higher than the preoperative IOP at 3 months (p = 0.024).
Conclusions
Scleral buckling without SRFD used to treat primary RRD afforded a high reattachment rate (compared to those of previous reports employing vitrectomy or scleral buckling with SRFD). Given the possible complications of SRFD, our method may be a safe and feasible surgical option, affording good results with few complications in patients with primary RRD.

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.

BACKGROUND: Community-acquired pneumonia(CAP) remains a leading cause of morbidity and mortality worldwide. Recently, the evolution of drug-resistant microorganisms has become a serious problem in CAP management. Specific antimicrobial therapy is the cornerstone of CAP management. However, obtaining an accurate etiologic diagnosis clinically is not easy and empirical antimicrobial treatment is usually administered prior to the correct microbiologic diagnosis. In this study, the clinical usefulness of empirical CAP treatment was investigated. METHODS: A total 35 cases were studied prospectively over a 16-month period in Mokpo Catholic Hospital from Dec. 1995 to Mar. 1997. The microbiologic diagnosis was made by sputum, blood culture, a specific serum antibody test and an immunologic study. RESULTS: The causative organisms were isolated in 10 (30%) out of 33 cases: 8 cases and 1 case on the sputum culture and blood culture respectively, and 1 case by an indirect hemagglutinin test. 12 cases had underlying diseases: pulmonary tuberculosis 4, alcoholism 4, diabetes mellitus 3, and liver cirrhosis 1. Antimicrobial treatment was given empirically and all cases recovered. CONCLUSION: A definite microbiologic diagnosis before commencing the appropriate treatment in CAP is not straightforward. Empirical therapy according to a clinical assessment is important and helpful. However, every effort to make the correct etiologic diagnosis should be taken.

OBJECTIVES: To evaluate the association of upper extremity musculoskeletal disorders with job demand-control and effort-reward related job stress. METHODS: Questionnaires concerning symptoms, psychosocial factors and work conditions were completed by 436 workers from a refrigerator assembly line, mobile phone assembly line, and an office, musculoskeletal conditions of the upper extremities were defined by the frequency, duration, and intensity of symptoms. A walk-through survey was performed to evaluate various physical work factors. Data were analyzed with the use of logistic regression. RESULTS: A total of 382 workers completed the survey, for whom neck and shoulder symptoms were the most frequently reported, followed by finger and wrist, and then elbow symptoms. Both awkward working posture and forceful exertion were associated with an increase in shoulder/neck and finger/wrist symptoms. In addition, job stress factors such as monotony, low job clarity, low job control, low promotion prospect, economic issues, and retirement pressures were associated with increased neck/shoulder, elbow, and finger/wrist conditions. Women were more likely to report symptoms, and the association between musculoskeletal conditions and job stress factors was stronger in female assembly line workers and office workers than in male assembly line workers. CONCLUSIONS: The results suggest that musculoskeletal conditions of the upper extremities are associated with not only physical work factors but also job stress factors. In particular, economic issues and career development factors are important influences on workers in Korea.

Purpose: To retrospectively compare the fixation methods for reattaching a trochanteric fragment in a pertrochanteric fracture treated with bipolar hemiarthroplasty. Materials and methods: Forty cases of an unstable femur pertrochanteric fracture were analyzed and followed up for average of 19(6~40) months. There were 18 cases fixed with tension band wiring (group 1), 7 cases treated using modified tension band wiring with K-wires (group 2) and 15 cases treated with the GTRD (Greater Trochanteric Reattachment Device) (group 3). Result: Group 1 was treated with simple a surgical procedure and the results were good. The second group had firm fixation postoperatively but required additional surgery in two cases to remove the K-wires because of wire migration after ambulation. Group 3 had relatively good results but required more dissection and a longer operating time. Conclusion: Tension band wiring or GTRD are good fixation methods for reattaching trochanteric fragments in pertrochanteric fractures. Moreover, tension band wiring is recommended for old osteoporotic patients due to a simple procedure and firm fixation. The use of modified tension band wiring using K-wire or a Steinmann-pin should not be used due to the possibility of distant migration.

Carcinoid tumors arising in the extrahepatic bile duct are very rare, accounting for only 0.2%~2% of all gastrointestinal carcinoid tumord. We experienced one case of a carcinoid tumor in the common bile duct. A 43-years-old man was unexpectedly found to have a carcinoid tumor of the common bile duct. This patient had no obstructive jaundice, yet we thought that this tumor was a clinically malignant tumor, so we performed pylorus preserving pancreatoduodenectomy. Pathologically, an ill-demarcated mass that measured 1.5x1.5cm in size had invaded into the pancreas. Immunohistochemically, the mass was founded to be chromogranin, synaptophysin and CD56 positive. The patient who underwent curative resection is alive and disease-free at time of this publication. This report also reviews the relevant literature on carcinoid tumors in the common bile duct.
