The purpose of this study is to evaluate the ventricular conduction abnormalities, especially RBBB, observed electrocardiographically after surgical closure of VSD. The present study population consists of 92 patients with VSD who were surgically corrected at the Hanyang University Hospital during 6 years period from Jan. 1985 to Dec. 1990. We reviewed their clinical records including surgical notes and EKG findings before and after operations. The results of the study were as follows: 1) Male to female ratio was 1.1:1 (48:44) 2) Out of a total of 92 cases of VSD, 65cases(70.7%)were perimembranous type and 27 cases (29.3%)were subarterial type. 3) The normal preoperative EKG findings were seen in 22 patients, LVH in 21 patients, BUH in 47patients, and RVH in 3 patiens. 4) A transatrial approach was performed in 55 cases, right ventriculotomy with or without resection of muscles in right ventricle in 13 cases, and pulmonary arteriotomy alone in 24 cases. 5) The right bundle branch block after operation developed in 33 patients out of the 65 patinets with perimembranous defect and 5 patients out of the 27 patients with subarterial defects. Postoperative RBBB developed more frequently in perimembranous defect than in subarterial defect. 6) Postoperative RBBB occured in 31.8% of the patients with normal preoperative EKG findings, 23.8% with preoperative LVH, 52.1% with BVH and 66.7% with RVH. Postoperative RBBB was more frequently observed in the patients group with preoperative BVH or RVH than the patients with normal or LVH. 7) Postoperative RBBB was observed in 84.6% after right wentriculotomy, in 43.6% after right atriotomy and in 12.5% with pulmonary arteriotomy alone.

BACKGROUND: The cause of idiopathic Parkinson's disease (IPD) is unknown. Recent studies suggest that IPD occurs less frequently in smokers than in non-smokers, but remains a controversial topic. We performed a case-control study to investigate the relationship between IPD and smoking in Korea. METHODS:The smoking histories of 624 IPD patients were compared with 622 age- and sex-matched control subjects at the Asan Medical Center. Detailed informa-tion on smoking behavior was identified from a questionnaire and self report. A conditional logistic regression was used to calculate the odds ratio (OR) and control for potential confounds. RESULTS: With "never-smokers" as the refer-ence category, there was an inverse association between past-smokers and IPD (OR 0.617, p=0.029), and a stronger inverse association of IPD with current-smokers (OR 0.389, p<0.001). When smokers were stratified by the interval "since quitting", there was an inverse association between those who stopped smoking more than 10 years ago and IPD (OR 0.753, p=0.31), and a greater inverse relationship with those who stopped smoking 1 to 10 years (OR 0.489, p=0.017). A significant trend of decreased risk of IPD with pack-years of smoking was detected. CONCLUSIONS: This study suggests that IPD occurs less often in smokers than in non-smokers. The inverse dose-response relationship between smoking and IPD provides indirect evidence that smoking is biologically protective.

A 19-year-old woman presented to our dental clinic with anterior crossbite and mandibular prognathism. She had a concave profile, long face, and Angle Class III molar relationship. She showed disharmony in the crowding of the maxillomandibular dentition and midline deviation. The diagnosis and treatment plan were established by a three-dimensional (3D) virtual setup and 3D surgical simulation, and a surgical wafer was produced using the stereolithography technique. No presurgical orthodontic treatment was performed. Using the surgery-first approach, Le Fort I maxillary osteotomy and mandibular bilateral intraoral vertical ramus osteotomy setback were carried out. Treatment was completed with postorthodontic treatment. Thus, symmetrical and balanced facial soft tissue and facial form as well as stabilized and well-balanced occlusion were achieved.

OBJECTIVE: The patients with spinal cord injury (SCI) suffered by a lot of complications that influence the quality of life both physically and mentally. The purpose of this study was to evaluate the epidemiology of patients with spinal cord injury in incidence of the complication according to the injury level and period. METHOD: Retrospective study was done in 554 patients with SCI who discharged from Yonsei University Medical Center from January, 1987 to December, 1996. We investigated the incidence of each complication such as respiratory, cardiovascular, genitourinary, musculoskeletal, and dermatologic complications according to the neurologic level and each period (1987~1991, 1992~1996). RESULTS: Among the 554 cases, urologic complication (40.3%) was the most common complication followed by dermatologic (39.0%), musculoskeletal (33.6%), cardiovascular (27.1%) and so on. The most common complications of each system were autonomic dysreflexia (13.2%) in cardiovascular, pneumonia (9.6%) in respiratory, contracture (27.8%) in musculoskeletal, urinary tract infection (34.3%) in urologic, hemorrhoid in gastrointestinal, and central pain (24.0%) in neurogenic complications. The most common site of pressure sore was sacral area (58.9%). There was no significant difference in each complication according to the injury period. CONCLUSION: Urologic complication was the most prevalent in patients with SCI followed by dermatologic, musculoskeletal and so on. These basic results would be helpful for prevention and management of the complication of SCI.

BACKGROUND AND PURPOSE: Benign paroxysmal positional vertigo (BPPV) is the most common form of vertigo. Although the repositioning maneuver dramatically improves the vertigo, some patients complain of residual dizziness. We evaluated the incidence and characteristics of persistent dizziness after successful particle repositioning and the clinical factors associated with the residual dizziness. METHODS: We performed a prospective investigation in 49 consecutive patients with confirmed BPPV. The patients were treated with a repositioning maneuver appropriate for the type of BPPV. Success was defined by the resolution of nystagmus and positional vertigo. All patients were followed up until complete resolution of all dizziness, for a maximum of 3 months. We collected data on the characteristics and duration of any residual dizziness and analyzed the clinical factors associated with the residual dizziness. RESULTS: Of the 49 patients, 11 were men and 38 were women aged 60.4+/-13.0 years (mean +/-SD), and 30 (61%) of them complained of residual dizziness after successful repositioning treatment. There were two types of residual dizziness: continuous lightheadedness and short-lasting unsteadiness occurring during head movement, standing, or walking. The dizziness lasted for 16.4+/-17.6 days (range=2-80 days, median=10 days). A longer duration of BPPV before treatment was significantly associated with residual dizziness (p=0.04). CONCLUSIONS: Residual dizziness after successful repositioning was observed in two-thirds of the patients with BPPV and disappeared within 3 months without specific treatment in all cases. The results indicate that early successful repositioning can reduce the incidence of residual dizziness.

An apocrine hydrocystoma is a translucent cystic nodule that looks like adenomatous cystic proliferation of an apocrine gland, which originated from a hair germ. Dermoid cyst is a cystic teratoma that contains developmentally mature skin appendages, such as hair follicles, sweat glands, and other tissues derived from the ectoderm. Many investigators believe that dermoid cysts re originated from the ectoderm, specifically the hair germ cells. A 58-year-old woman was presented with a purple, asymptomatic, dome-shaped nodule on her right lower eyelid that had been slowly increasing in size for several years. Histopathological examination revealed two well-demarcated cysts: one was lined with stratified squamous epithelium with mature hair and sebaceous glands and the other contained large cystic spaces, which papillary projections extended. We report a rare case of a dermoid cyst, combined with an apocrine hydrocystoma, occurring in the right lower eyelid.
