1. Many design features including suture type, anchor size and geometry, and anchor material, play a role in the overall strength of the anchor. In addition, technical considerations such as implant orientation, pattern, and location may affect the ultimate success of the repair. 2. Multiple fixation points provide a biomechanically sounder construct in Bankart repair. The size of the glenoid and its rim make anchor size a critical consideration in implant selection and implementation.

Early recognition, vigorous preoperative preparation, sophisticated supportive care, control of sepsis, and intensive care nursing have produced remarkably improved results in the management of esophageal atresia. Successful surgery for esophageal atresia and tracheoesophageal fistula was carried out recently. Two neonates with esophageal atresia and distal tracheoesophageal fistula were type C. Transpleural end-to-end repair was carried out after gastrostomy due to low birth weight in case I associated with ventricular septal defect. Case 2 underwent primary retropleural end-to-end repair. A simple one-layer anastomosis with the sutures passing through all layers of`the esophagus was performed in all cases.

견관절 상완순 전후방(SLAP: Superior labrum anterior to posterior) 병변은 상부 관절와순 단독 손상으로 발견되기도 하고, 견관절 재발성 탈구 환자에서 전하방 관절와순의 파열, 즉 Bankart 병변의 연장으로 상부 관절와순까지 파열이 진행된 동반 손상으로 발생하기도 하며, 드물게 후방 Bankart 병변을 동반하는 경우도 있다. 여러 가지 병변과 동반된 SLAP 병변이 보고되어 왔으나 그 중 후방 Bankart 병변과 동반하여 발생한 후방 II형 SLAP 병변에 대한 보고는 미미하고 그 병변에 대한 관절경적 복원술 시 봉합 나사(suture anchor)의 삽입과 봉합에 주의할 점이 있다. 저자들은 투구 동작과 같은 흔한 손상 기전이 아닌 팔을 뻗친 상태에서 넘어지면서 발생한 외상으로 야기된 본 증례에 대해 관절경적 복원술을 시행하여 만족할 만한 결과를 얻었기에 보고하는 바이다.

During the period from March, 1963, to November, 1977, forty-eight patients with secundum type atrial septal defects have undergone surgical repair using cardiopulmonary bypass with a pump oxygenator at the Seoul National University Hospital. Twenty-six [55 percent] of the patients were females and Twenty-two [45 percent] were males. The patients varied in age from 3 years to 51 years. We have divided secundum defects into three types. These are: 1] the high defect; 2] Ovale type defect; and 3] low defect including the defect in the area of the coronary sinus. An ovale type defect was present in forty-one cases [85 percent]. Partial anomalous pulmonary venous connections were present in two patients in the high defect group. All of the forty-eight patients had had right heart catheterization before operation. The pulmonary to systemic flow ratio [Qp/Qs] was determined in our 38 patients. The Qp/Qs was less than 1.5/1 in only five of the 38 patients. Among the 33 patients with moderate and severe left-to-right shunts [Qp/Qs 1.6-3.5/1], the systolic pulmonary artery pressures. ranged from 30 to 80 mm Hg. Large left-to-right shunts [Qp/Qs>3.6/1] were present in 13 patients. The postoperative complications occurred in 13 patients [27. 1 percent]. Postoperative wound infections were the most frequent complications being present in 6 patients [12.5%]. Forty-six of the patients with secundum atrial septal defects survived surgical repair of their defects. Thus the hospital mortality of surgery was 4.2 percent. The causes of death in the early postoperative period were: 1] low cardiac output syndrome related to severe pulmonary hypertension in one case; and 2] postoperative several bleeding in one case.

Background: DNA polymerase is a single-copy gene that is considered to be part of the DNA repair machinery in mammalian cells. The encoded enzyme is a key to the base excision repair (BER) pathway. It is evident that pol beta has mutations in various cancer samples, but little is known about ovarian cancer. Aim: Identification of any variant form of $pol{\beta}$ cDNA in ovarian carcinoma and determination of association between the polymorphism and ovarian cancer risk in Indian patients. We used 152 samples to isolate and perform RT-PCR and sequencing. Results: A variant of polymerase beta (deletion of exon 4-6 and 11-13, comprising of amino acid 63-123, and 208-304) is detected in heterozygous condition. The product size of this variant is 532 bp while wild type pol beta is 1 kb. Our study of association between the variant and the endometrioid type shows that it is a statistically significant factor for ovarian cancer [OR=31.9 (4.12-246.25) with p<0.001]. The association between variant and stage IV patients further indicated risk (${\chi}^2$ value of 29.7, and OR value 6.77 with 95% CI values 3.3-13.86). The correlation study also confirms the association data (Pearson correlation values for variant/stage IV and variant/endometrioid of 0.44 and 0.39). Conclusion: Individuals from this part of India with this type of variant may be at risk of stage IV, endometrioid type ovarian carcinoma.

From January 1962 to March 1987, 97 patients underwent operation for mitral valve disease. Of these patients, 61 [62.9%] required mitral valve replacement. Thirty-six patients [37.1%] had mitral valve repair. The mean age was 26.9*11.6 years [range 5 months to 48 years]. There were 32 [88.9%] cases of rheumatic valve disease, 4 [11.1%] cases of congenital mitral valve disease. Valve dysfunction was classified into three types: type I [normal leaflet motion], 6 patients; type II [prolapsed leaflet], 1 patient; type III [restricted leaflet motion], 29 patients. Twenty-nine patients [80.6%] had pure or predominant stenosis and 7[19.4%] had pure regurgitation. No patient was in NYHA functional class I. Three patients [16.7%] were in functional class II, 15[83.3%] were in functional class II. The techniques used included closed mitral commissurotomy [16 patients], open mitral commissurotomy [13 patients], localized Wooler type annuloplasty [4 patients], suture repair of leaflet defect [3 patients], chordal shortening [1 patient], Carpentier ring annuloplasty [1 patient], and fenestration of fused chordae [1 patient]. There were two perioperative deaths [5.6%], related to left ventricular failure and reoperation. The survivors were followed up for 94 patient-years [mean 4.68*5.54 years]. One late death [1.1*1.1% per patient-year] occurred and was valve related. Reoperation was required in 3 patients, of whom 2 were deaths. There was 1 case [1.1*1.1% per patient-year] of thromboembolism. No patient received anticoagulant after operation. At 10 year, 92*7.4% of the patients were still alive. The actuarial survival rate of patients free of valve-related complication was 79*6.4% at 6 years, 27*12.1% at 11 years. After surgery, 18 patients [88.9%] were in NYHA functional class I or II.

We reviewed the results of arthroscopic surgery in patients with rotator cuff disease. Arthroscopic subacromial decompression(ASD) was performed on 22 patients with rotator cuff disease who had not responded to nonoperative measures. In the patients who had a complete tear of the rotator cuff(four of ten Neer's stage III patients), mini-open repair also was performed. Results were determined by questioning patients about their satisfaction with the outcome of surgery and by functional assessment of the shoulder with the parameters of pain, function, and range of motion according to the UCLA shoulder rating scale. The average follow-up was 21 months. The results were sixteen(72%) excellent, three(14%) good, two(9%) fair, and one(5%) poor. The following variables were analyzed to assess their influence on final outcome; duration of preoperative symptoms, Neer's stage(extent of damage to the cuff), type of acromion. Satisfactory results were achieved in thirteen of fourteen patients(93%) who had duration of preoperative symptoms below one year, and in four of six(67%) above 2 years. And satisfactory results were achieved in eleven of twelve patients(92%) who had Neer's stage II and in eight of ten(80%) stage III and achieved in six of seven patients(86%) who had Bigliani's acromion type I, in nine of eleven(82%) type II, and in four of four(100%) type III. There are multiple factors that may influence the recovery after ASD or the eventual outcome. However, although there is still a controversy about the pathogenesis of rotator cuff disease, We found that arthroscopic subacromial decompression and mini-open repair in patients with rotator cuff disease were well enough documented to be considered a standard treatment.
