BACKGROUND: To evaluate the efficacy of Fibrin glue to decrease recurrence in video-assisted thoracoscopic surgery(VATS) for a treatment of spontaneous penumothorax. MATERIAL AND METHOD: All medical records of 17 patients who underwent a thoracoscopic wedge resections of bullae with stapling device with Fibrin glue in our institute between May 1998 and December 1999 were reviewed. variables analyzed include affected sites primary indication of VATS. duration from admission to discharge duration of postoperative stay duration of chest tube drainage recurrence and complication. There were 16 men and 1 woman. RESULT: There was no evidence of hemodynamic instability or arterial blood gas abnormalities encountered during the procedure. Mean age at the time of the VATS was 26.9 years (range 15 to 61 years) The mean duration from admission to discharge was 7.8 days and mean postoperative stay was 5.1days mean chest tube indwelling period was 4..0 days. There was no recurrence of pneumothorx. CONCLUSION: Thoracoscopic wedge resections with introduction of fibrin glue are safe and effective and requires only a short hospital stay. We believe that this thoracoscopic technique will further simplify the surgical treatment of pneumothorax.

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.

PURPOSE: Concurrent chemoradiation treatment (CCRT) for locally advanced rectal cancer is an important modality for curative resection, but its tumor response shows wide spectrum. The aim of study is to investigate any correlation between a related genetic mutations, proliferative index and tumor response after CCRT. METHODS: A twenty three patients with rectal cancer, which preoperatively staged as over T3N1 or T4 determined by transrectal ultrasonography and MRI. Enrolled patients were given 5 FU 450 mg/m2 and leucovorin 20 mg/m2 intravenously for 5 days during the first and fifth weeks of radiation therapy (45~54 Gy). 4 weeks after completion of scheduled treatment, surgical resection was performed. Tumor response was classified into CR (complete remission), PR (partial response: 50% of diminution of tumor volume and downstaging), NR (no response). Paraffin-embedded tissues obtained before chemoradiation treatment were studied with immunohistochemical staining of p53, Bcl-2 and Ki-67. The extent of tumor response was correlated with proliferative activity as measured by immunostaining of Ki-67 proliferative antigen and expression of p53 and bcl-2 oncoproteins (less than 10%: negative, 10~25%: , 25~50%: , more than 50%: , Ki-67: to count a labeled cells per 1,000 cells). RESULTS: All patients were resectable. CR was obtained in 4 (17.4%), PR in 10 (43.3%) and NR in 9 (39.2%). p53 mutation was noted in 16 (70%). p53 mutation was found in NR: 5 (31.3%), PR: 9 (56.2%), CR: 2 (12.5%), respectively. Bcl-2 expression was noted in 11 (48%). NR as in 4 (36.3%), PR: 3 (28.4%) and CR: 4 (36.3%), respectively. Ki-67 labeling index was NR: 615.4 446.2, PR: 663.2 296.4, CR: 765.5 188.3, respectively (CR PR Vs NR, p=0.029). CONCLUSIONS: Immunohistochemical Expression of p53 and bcl-2 does not correlate with tumor response after CCRT, but Ki-67 labeling may be useful parameters for good radiosensitive tumor selected for CCRT.

OBJECTIVES: If teeth are missing, super-eruption of teeth in the opposing arch can occur in the area and can change the occlusal plane. When missing teeth are replaced with implants, the oral surgeon must determine whether or not the super-erupted teeth need to be treated in order to normalize the occlusal plane. In this study, we evaluated the clinical prognosis of dentition after implant placement and prosthetic treatment were completed in an occlusal plane altered by super-erupted teeth in the opposing arch without additional treatment of the super-erupted teeth. MATERIALS AND METHODS: Twenty-two patients (9 males, 13 females) were treated with implants and prosthetics without addressing the super-erupted opposing dentition from April 2004 to August 2012 at Seoul National University Bundang Hospital. A total of 33 implants were placed. Values of crestal bone loss, survival rates, and surgical and prosthetic complications for an average of 29.6 months after prosthetic loading were recorded. RESULTS: In one case, the cover screw was exposed after implant surgery. The mean crestal bone loss was 0.09±0.30 mm. Of the 33 implants, 31 survived, a survival rate of 93.94%. A prosthetic complication occurred in one case but functioned well after correction. CONCLUSION: Favorable clinical results from prosthetic complications, crestal bone loss, and implant survival rates were exhibited in implants next to a super-erupted opposing tooth.

PURPOSE: The purpose of this study is to assess the 5-year outcome of patients considering surgery for complaint of cervical and radiating pain treated by selective nerve root block (SNRB). MATERIALS AND METHODS: Between January 2001 and December 2007, 39 cases were selected from patients who underwent SNRB before the operation and were followed-up for more than five years. The mean follow-up period was 64.3 months and the mean age was 57.7 years. The patients were divided into the operation group and the only cervical SNRB group. The groups were compared for gender, age, duration, disease, single or multi-level, and root compression rate on magnetic resonance imaging. The clinical results were analyzed using the neck disability index (NDI) and the visual analogue scale (VAS) score. RESULTS: Among the 39 cases scheduled for the operation, 20 cases (51.3%) did not proceed to the operation and 13 cases among them were treated with additional conservative treatment. The average VAS score for the operation group and the cervical SNRB group was 8.1 points and 7.5 points at the preoperative state and the pre-injection state. After surgical treatment and cervical nerve root block, the scores were 3.0 points for all. The NDI for the operation group was 11.3 points at the last follow-up. The NDI for the cervical nerve root block group was 13.6 at the last follow-up. There was no significant difference between the two groups. Shorter duration and younger age tended to show a higher operation rate. At the last follow-up, 7 cases (17.9%) after cervical SNRB had persistent symptom relief without other treatment. CONCLUSION: Cervical SNRB is considered an effective treatment for patients with cervical disease with radiating pain and who are scheduled for an operation.

PURPOSE: The prevalence of atopic diseases has been increasing remarkably. The less frequent opportunities for infection early in life, especially mycobacteria exposure, parallel this higher prevalence of atopic diseases. Bacille Calmette-Gu rin (BCG), a potent inducer of Th1 immune response, has been suggested to suppress Th2 response which is known to mediate IgE-mediated atopic disorders. This study was done to investigate whether there is any relation between the number of BCG scars and the prevalence of atopic disorders in early childhood. METHODS: We surveyed 393 parents with a children who were given percutaneous multi- puncture BCG vaccination within four weeks after birth. The main questions concerned the past history and present illness of physician-diagnosed atopic diseases (atopic dermatitis, bronchial asthma, and allergic rhinitis), the number of BCG scars (range; 0-18), and potential confounders such as gender, parental atopy, maternal smoking and environmental cofactors. The prevalence rate of each atopic disease was measured and analysed according to the number of BCG scars. RESULTS: Each prevalence rate was 18.1% for atopic dermatitis, 9.4% for bronchial asthma, 14.6% for allergic rhinitis, and 32.3% for any of them. All of them had received BCG vaccination during the first four weeks of life. The children with 15 or more BCG scars had a significantly lower prevalence of any atopic disease (22/99, 22.2%) as compared to those with four scars or less (51/125, 40.8%) by simple regression analysis. (P value=0.02) But this association was not significant after controlling for potential confounders. (P value= 0.26) CONCLUSION: This survey demonstrated a weak relation between a larger number of BCG scars and less atopy development at early childhood. But the relation was not so significant. Further studies are needed.

PURPOSE: The aims of this study were to investigate the incidence of rehospitalization for very low birth weight (VLBW) infants due to respiratory illness during the first year of life, and to examine the association between rehospitalization with respiratory distress syndrome (RDS) and duration of mechanical ventilation. METHODS: Twenty-three VLBW infants admitted to neonatal intensive care unit (NICU) at Dae-Dong Hospital from January 1996 to December 2002 were studied. Twenty-three of full-term infants born from January 2001 to December 2002 at Dae-Dong Hospital were studied as control group. Parental questionnaire were collected and hospital records of VLBW infants and control group were reviewed retrospectively. RESULTS: The rate of rehospitalization for respiratory illness in VLBW infants (16/23, 69%) was greater than that of term infants (6/23, 26%) (P< 0.05). Ventilated group with RDS (14/ 19, 73%) in VLBW infants had more rehospitalization compared to non-ventilated group (2/4, 50%) (P< 0.05). Those with ventilator care longer than 7 days (7/7, 100%) had more rehospitalization than those with ventilator care less than seven days (7/12, 58%) (P< 0.05). Fifty nine percent of rehospitalization occurred from December to March. Sixty five percent of rehospitalized infants required admissions between 5 and 8 months after NICU discharge. CONCLUSION: VLBW infants are more likely to have rehospitalization with respiratory illness during first year, especially VLBW infants with RDS and prolonged care of mechanical ventilation. It is important to prevent these susceptible infants from respiratory infections and to follow-up them periodically because VLBW infants tend to show decreased pulmonary function subsequently.
