The lateral meniscus is morphologically more variable than the medial meniscus. An abnormal lateral meniscus also varies with respect to its size, shape and stability, and such variations can occur in any patient of any age. The most common variant is a discoid lateral meniscus. We recently encountered a patient with a discoid lateral meniscus for which the anterior horn of the meniscus was anomalously inserted into the anterior ACL. The patient was forty five years old women who had persistent pain for three to four years without any specific trauma history. She was preoperatively diagnosed as having discoid lateral meniscus by MRI, and was confirmed the presence of the complex tear and anomalous insertion of the anterior horn of the discoid lateral meniscus into the anterior ACL by arthroscopic examination. Arthroscopic subtotal meniscectomy was performed and the symptoms were improved after surgery.

Background: Little information is available concerning the value of bronchoscopy in patients with a lymphocytic exudative pleural effusion in which percutaneous pleural biopsy have been regarded as cornerstone in investigating the etiology. Recently, a few reports suggest that bronchoscopy may be more effective diagnostic method in patients with unexplained pleural effusion accompanied by hemoptysis or other roentgenographic abnormalities, such as mass, infiltrate, atelectasis. Method: Mter initial examinations of sputum and pleural fluid through thoracentesis in 112 patients(male 75 cases, female 37 cases, mean age 53.2 years) who were admitted for evaluation of the cause of pleural effusion, we performed bronchoscopy and closed pleural biology in most patients with undiagnosed lymphocytic exudate and compared the diagnostic yield of both invasive methods according to hemoptysis or other roentgenographic abnormalities, and investigated the sole diagnostic contribution of bronchoscopy. Results: Tuberculosis(57 cases, 51%) was the most common cause of pleural effusion. Percutaneous pleural biopsy showed more diagnostic yield than bronchoscopy regardless of presence or absence of other clinical or radiologic abnormalities. In 25 cases with unknown etiology after pleural biopsy, additional diagnostic yield by bronchoscopy was 36 % (4/11) in patients with associated features and only 7 % (1/14) with lone effusion, and, as the sole mean for diagnsosis in all patients with pleural effusion, was only 4.5%(5/12). Conclusion : In a region of high prevalence of tuberculosis as a cause of pleural effusion, percutaneous pleural biospy is more effective method when invasive method is required for confirmative diagnosis of unexplained lymphocytic exudative pleural effusion, and bronchoscopy is unlikely to aid in the diagnosis of lone pleural effusion.

Purpose: The bone defects that are associated with shoulder anterior instability may be the causes of failure of arthroscopic surgery. For the treatment of traumatic shoulder instability, we tried to determine the arthroscopic techniques that can be used for the bone defect of the glenoid and the humeral head. The purpose of this study is to assess the surgical techniques for the arthroscopic reconstruction of the shoulder with anterior instability and bone defects. Materials and Methods: We analyzed the articles that have been recently published on anterior shoulder instability and we assessed the arthroscopic surgical techniques. We compared the articles and the methods of arthroscopic surgical techniques for treating bone defects of the anteroinferior glenoid and the posterolateral humeral head, which were considered as the causes of recurrence of shoulder instability. Results: There are the anteroinferior bone defects of the glenoid and Hill-Sachs lesions in the bone defects that appear in patients with anterior shoulder instability. These bone defects are currently the causes of failure of arthroscopic surgery. Conclusion: Open shoulder surgery may be the treatment of the choice for a shoulder with instability and significant bone defects of the glenoid and the humeral head. But efforts are being made to overcome the weaknesses of open surgery by the use of arthroscopy.

Background : The incidence of pulmonary tuberculosis has been reducing, but endobronchial tuberculosis continues to be a signigicant heath problem. We performed prospectively bronchoscopy in patients diagnosed with pulmonary tuberculosis in order to evaluate the frequency of endobronchial tuberculosis and its related findings. Follow-up bronchoscopy was also performed after treatment to evaluate the incidence of endobronchial complications such as stenosis and remaining lesions. Methods : From January, 1999 to December, 2003, bronchoscopy was performed on patients newly diagnosed with pulmonary tuberculosis. Results : 458 patients were enrolled in this study, out of 699 patients with pulmonary tuberculosis from 1999 to 2003. 234(51%) had endobronchial tuberculosis. The frequency was 40.3% in males and 66.3% in females, The most common symptom was nonspecific cough and sputum, and the main radiologiy finding was patchy infiltration. The most common subtype of endobronchial tuberculosis was the edema-hyperemic form. The right lung was involved more frequently than the left, and the left upper lobe was the most commonly involved site. 58 patients underwent follow-up bronchoscopy and most of been cured without major sequels. However, 8 patients had a stenosis of trachea and main bronchus, and 6 patients had still had endobronchial lesions. Therefore the treatment was prolonged for 3 months. Conclusion : Endobronchial tuberculosis of pulmonary tuberculosis has been remained of high incidence. bronchoscopic and follow-up bronchoscopy examination needs to evaluate the incidence of endobronchial tuberculosis and its related findings and major complication despite of treatment.

Purpose: This study evaluated the differences in associated shoulder lesions on complete rotator cuff tear patients regarding ages and gender. Materials and Methods: Between June 2003 and March 2006, 109 patients (59 males, 50 females) who received arthroscopic shoulder surgery for their complete rotator cuff tear were selected and their associated shoulder lesions were analyzed. Ages were between 24 years, the youngest, and 75 years, the oldest. Groups by age were under 59 years group and over 60 years group, and associated lesions of patients to be analyzed were Acromioclavicular arthritis, SLAP(shoulder labrum anterior and posterior) lesion, and biceps tendinitis, and statistic analysis were performed by Khai-square method. Results: For acromioclavicular joint arthritis, over 60 years old group showed higher association rate compared to under 59 years young group, and for SLAP lesions, under 59 years young group showed higher association rate compared to over 60 years old group only in men. Conclusion: For diagnosis and treatment of complete rotator cuff tear patient, associated shoulder lesions in different ages should be considered, especially associations of SLAP lesions in young male patients, and acromioclavicular joint arthritis in old age patients should be verified.

SLAP(Superior labrum anterior to posterior) lesion is found in superior labrum injury alone and also combined with extension of the Bankart lesion(anteroinferior labral tear) in recurrent shoulder dislocation patients and rarely accompanied by the posterior Bankart lesion. There have been reports about SLAP lesions associated with various lesions, however, posterior type II SLAP lesion associated with posterior Bankart lesion has been rarely reported. In such a case, there are important technical tips in inserting anchors and suturing during arthroscopic repair. We experienced a rare case of posterior type II SLAP lesion associated with posterior Bankart lesion, occurred not after repetitive throwing(common mechanism) but after trauma in slipping down with the arm stretched during riding a bicycle. The satisfactory result was obtained after arthroscopic repair in this case.

Purpose : Renal cystic diseases comprise a mixed group of heritable, developmental and acquired disorders. Recently the use of imaging modalities such as ultrasonography and radionuclide scanning has increased the detection rate of renal cystic diseases. We studied to review the clinical features and treatment of renal cystic diseases in children. Methods : This study was performed in 95 children with renal cystic diseases in the Department of Pediatrics, Asan Medical Center from October 1989 to June 2001. Results : In 95 patients, there were 55 cases(58.0%) with multicystic dysplastic kidney(MCDK), 19 cases(20.0%) with simple renal cysts, 13 cases(13.7%) with hereditary polycystic kidney diseases( 7 with autosomal recessive type, 5 with autosomal dominant type, 1 with undetermined), 6 cases(6.3%) with renal cysts in tuberous sclerosis and 1 case(1.0%) with medullary cystic disease. All MCDK patients had no renal dysfunction and hypertension during the follow-up period. Three out of 13 with polycystic kidney diseases had progressed to end-stage renal disease during the follow-up period. One case with a simple cyst underwent laparoscopic malsupialization for decompression. Conclusion : Renal cystic diseases have diverse clinicopathologic features and variable prognosis. We emphasize that routine follow-up should be performed to prevent and to detect early treatable complication in renal cystic diseases. Therefore, their natural history and treatment need further investigation and long term follow-up is required.

Purpose: Non-alcoholic fatty liver disease (NAFLD) has been recognized as an important childhood liver disease, especially where the prevalence of childhood obesity is increasing. The purpose of this study is to clarify the usefulness of elevated serum aminotransferase activities and their ratio for predicting the presence of fatty liver and its severity in obese children. Methods: Forty-four children (M/F 29/15, age 4 to 16 years) with obesity (weight excess>20%) were analyzed retrospectively with medical records based on degree of obesity, bioelectrical impedence, serum aminotransferase activities, lipid profiles and ultrasonography. Results: 1) Ultrasonography was carried out in 34 cases. Elevated serum ALT was found in 89.7% (26/29) of the patients diagnosed as fatty liver by ultrasonography and decreased AST/ALT ratio (<1) was found in 96.6% (28/29). There was a strong correlation between elevated serum ALT (>45 IU/L) or decreased AST/ALT ratio (<1) and the fatty liver in obese children (p<0.05). 2) There was no significant correlation between the serum ALT or AST/ALT ratio and the degree of fatty liver (p>0.05). 3) There was a significant correlation between total cholesterol, triglyceride and fatty liver (p<0.05). Conclusion: Serum ALT activity and AST/ALT ratio were useful to predict the presence of fatty liver diagnosed by ultrasonography in obese children, whereas they were not useful to predict the degree of fatty liver. Therefore, to prevent fatty liver progressing to advanced liver disease, it is necessary to manage and monitor the obese children continuously, especially those who have predicting factors of fatty liver.

We present a case of coronary artery fistula originating from the proximal left anterior descending artery draining into the main pulmonary artery, which was associated with atrial septal defect. The patient was a 56 year old male who was admitted for exertional dyspnea and abdominal distension. Echocardiogram and selective coronary arteriogram revealed a atrial septal defect and fistulous connection. The patient underwent surgery under the cardiopulmonary bypass with fibrillating heart. The pericardial patch closure of atrial septal defect and internal obliteration of the fistula termination site in the main pulmonary artery were performed. Postoperative hospital courses were uneventful without any specific complication and the patient was discharged without problem.
