STATEMENT OF PROBLEM: Many dental clinicians are concerned about immediate loading of inserted implants. However, there have been few clinical studies surveying the success rates of immediate loading, based on Korean implant systems. PURPOSE: The aim of this study was to evaluate the outcome of immediate functional loading of the implant (SinusQuick(TM) EB, Neobiotech Co., Seoul, Korea) in partially edentulous maxilla or mandible. MATERIAL AND METHODS: Total 15 implants were placed. Within 2 weeks after implant insertion, provisional implant-supported fixed partial dentures were delivered to the patients. Quantitatively, marginal bone loss was measured at the time of immediate loading, after 3-months of continued loading and at the last follow-up. The mean follow-up period was 4.8 months. RESULTS: Mean marginal bone loss from implant surgery to early loading, 3-months follow-up and last follow-up was 0.03 +/- 0.07 mm, 0.16 +/- 0.17 mm and 0.29 +/- 0.19 mm. No implant failed up to 6 months after insertion, resulting in a 100% survival rate. CONCLUSION: Immediate loading exhibited high success rate in partial edentulism for up to 6 months. Well-controlled long term clinical studies with large sample size are necessary to confirm this finding.

BACKGROUND: The rate of suicide of adolescents is recently significantly increasing in South Korea. Suicide is the first leading cause of death of adolescents aged 15 to 19 years in South Korea and the mortality rate due to suicide of adolescents is 8.9 per 100,000. The aims of this study is to investigate factors that affect suicidal ideation through inventory and scale. METHODS: A questionnaire was conducted to 820 high school students in a city, and 776 subjects who finished questionare were included in this study. Suicidal ideation, school bullying, excessive sexual thought and family conflict were checked by adolescent mental health and problem behavior screening questionnaire-II (AMPQ-II). Internet addiction degrees and depression was evaluated by internet addiction scale (IAS) and Beck's depression inventory (BDI), respectively. RESULTS: AMPQ-II, IAS, BDI, school bullying, suicidal ideation, and family conflict were closely related to each other. Binary logistic analysis showed that victims of school bullying (odds ratio [OR], 2.3; 95% confidence Interval [CI], 1.439-3.816), AMPQ-II high risk (OR 4.9; CI 2.546-9.433) and depression of all grade (OR 1.8 [mild], 2.2 [moderate], 6.4 [severe]) were related to suicidal ideation. CONCLUSIONS: Presence of school bullying, depression, and AMPQ-II high risk were closely related to suicidal ideation of high school students. Thus, AMPQ-II and BDI score can use as a screening tool for adolescent suicide ideation.

Heterotopic pregnancy is defined as simultaneous intrauterine and extrauterine pregnancy. The incidence of heterotopic pregnancy was about 1 to 30,000 pregnancies, but it has been increased. This increased incidence is explained by the rise in PID, pelvic surgery, IUD and assisted reproductive technologies-in vitro fertilization/gamate intrafallopian insemination/intrauterine insemination. Thus careful pelvic examination combined with serial beta-hCG determinations and transvaginal sonography to evaluate the adnexal region are necessary prerequisites for early diagnosis. We report a case of heterotopic pregnancy following in ovulation induction and intrauterine insemination with a brief review of literature.

The simultaneous occurrence of a renal cell carcinoma and a urothelial carcinoma in the same kidney is uncommon. Here we report the case of a 79-year-old woman with ipsilateral synchronous renal cell carcinoma and urothelial carcinoma. She was referred to our hospital for gross hematuria and right flank pain. A computed tomography scan showed a 15x20 mm enhanced lesion on the upper calyx and a 12x15 mm mass on the lateral aspect of the right kidney. We thus suspected a renal pelvis tumor and performed right hand assisted laparoscopic nephroureterectomy with bladder cuff excision (HALSNU). Gross findings were multiple, pale yellowish papillary masses on the upper and lower major calices, of which the largest one measured 16x20 mm. A separated solid mass measuring 12x16 mm was also noted on the anterior midportion of the kidney. The former was a urothelial carcinoma and the latter was a chromophobe renal cell carcinoma. We present a rare case of a chromophobe renal cell carcinoma and a urothelial carcinoma in the same kidney.

A 59 year-old woman who had suffered daily headaches was diagnosed with leptomeningeal metastasis. Leptomeningeal metastasis is uncommon but devastating form of metastatic spread. Cerebral venous thrombosis is a disease sometimes associated with systemic cancer. Rarely, cerebral sinus occlusion accompanies leptomeningeal cancer. We report a patient who had cerebral sinus thrombosis and leptomeningeal metastasis.

Diaphragmatic eventration is a rare disease and is caused by congenital etiology. We operated on a patient who had had preexisting left diaphragmatic eventration which was complicated by a right diaphragmatic paralysis and a persistent respiratory insufficiency due to a traffic accident. This was a very rare case and there has not yet been any case reports worldwide. We were able to abtain good surgical results from plication of left diaphragm in this case and thus report it.

BACKGROUND: With the advent of thoracoscopy, there has been increasing interest in less invasive surgical bullectomy and pleurodesis. The recurrence rate, however, has been reported higher in surgery with thoracoscopy than with open thoracotomy and it is thought to be caused by inappropriate mechanical pleurodesis during thoracoscopic surgery. MATERIALS AND METHODS: We compared the short-term recurrence rates according to the intensities of pleural abrasion in 62 patients who underwent VATS for treatment of spontaneous pneumothorax from April 1996 to August 1997. The patients were divided into 2 groups: group A (n=32) included patients who received relatively weak pleural abrasion using Endo-forcep instrument for grasping the gauze, and group B (n=30) received strong pleural abrasion using conventional instrument wrapped tightly with gauze. Each intensity of pleural abrasion allowed petechia on the parietal pleura in group A, and some tearing and bleeding in group B. RESULTS: Indications for operation, sex distribution, and age were comparable in both groups. There were no differences in chest tube indwelling time (3.78+/-3.35 vs 3.80+/-2.49 days), hospital stay (4.72+/-1.87 vs 4.67+/-2.20 days), and the amount and duration of analgesics required postoperatively. Persistent air-leak more than 7 days after surgery occurred in 4/32 (12.5%) and 2/30 (6.7%) in group A and B, respectively. No bleeding-related complication occured. Pneumothorax recurred 12.5% (4/32) and 0% (0/30) of patients at a mean follow-up of 9.7 and 9.6 months in group A and B, respectively, and it was statistically significant (p<0.05). CONCLUSIONS: Proper intensity of pleural abrasion is very important factor to reduce recurrence after VATS for spontaneous pneumothorax. During short-term follow-upafter surgery, we could achieve excellent result in reducing recurrence rate with VATS and strong pleural abrasion which is comparable to thoracotomy.

BACKGROUND: Multi-loculated empyema makes treatment difficult, and more so when thoracentesis or chest tube drainage fails. MATERIALS AND METHODS: From December 1991 to December 1997, we performed closed rib resectional drainage for 18 cases of loculated empyema on the fibrinopurulent or early chronic phase. RESULTS: Surgery was performed on patients with loculated empyema complaining of persistent symptoms due to failure of treatment by thoracentesis (8 cases) or chest tube drainage (10 cases). Predisposing factors of empyema were pneumonia in 13 cases, clotted hemothorax in 3 cases, cholecystectomy, and tuberculous pleurisy in 1 case. Causal organisms were cultured in 8 cases (42.1%), and methicillin-resistant staphylococcus aureus was found in 3 cases, pseudomonas aeruginosa in 2 cases, and enterococcus aerogens, alpha-hemolytic streptococcus, and acinetobacter baumannii were found in 1 case. Size of loculations was various, and computed chest tomogram showed multiple loculations of empyema numbering 1~4 (mean 1.78+/-1.00). Operating time was relatively short, about 55~140 mins (mean 102.8+/-30.8). All toxic symptoms including fever disappeared postopratively and general conditions improved very quickly in all patients. Length of chest tube indwelling time and hospital stay after surgery were 3~42 days (mean 11.4+/-11.5) and 6~36 days (mean 12.9+/-8.1), respectively. Complications of prolonged drainage occurred in 2 cases and no death occurred. There were no recurrences and chest x-rays taken 3~6 months after surgery showed normal findings in 14 cases and slight pleural thickening in 4 cases. CONCLUSIONS: Closed rib resectional drainage requires very simple techniques and has excellent outcomes and little complications, therefore, we think that it is the choice of operation for patients with loculated empyema on the fibrinopurulent or early chronic phase.
