A statistical comparison of pulmonary artery and pulmonary venous wedge pressure has been made by the correlation coefficient method in 24 children with various congenital heart disease. None of them had pulmonary hypertension above the normal range. During the systolic phase, pulmonary arterial pressure was 2.02+/-2.64mmHg greater than pulmonary venous wedge pressure with poor correlation(r=0.57). During the diastolic phase, pulmonary venous wedge pressure was 2.08+/-2.47mmHg greater than pulmonary aetery pressure with poor correlation(r=-.63). Mean pulmonary arterial pressure was 0.79+/-1.02mmHg greater than pulmonary venous wedge pressure with good correlation (r=0.96). Therefore, it is concluded that if pulmonary artery is not entered, a pulmonary vein wedge pressure is a useful indication of pulmonary artery mean pressure in selected cases of congenital heart disease.

Long-standing intestinal inflammation in patients with inflammatory bowel disease (IBD) induces dysplastic change in the intestinal mucosa and increases the risk of subsequent colorectal cancer. The evolving endoscopic techniques and technologies, including dye spraying methods and high-definition images, have been replacing random biopsies and have been revealed as more practical and efficient for detection of dysplasia in IBD patients. In addition, they have potential usefulness in detailed characterization of lesions and in the assessment of endoscopic resectability. Most dysplastic lesions without an unclear margin, definite ulceration, non-lifting sign, and high index of malignant change with suspicion for lymph node or distant metastases can be removed endoscopically. However, endoscopic resection of dysplasia in chronic IBD patients is usually difficult because it is often complicated by submucosal fibrosis. In patients with dysplasias that demonstrate submucosa fibrosis or a large size (≥20 mm), endoscopic submucosal dissection (ESD) or ESD with snaring (simplified or hybrid ESD) is an alternative option and may avoid a colectomy. However, a standardized endoscopic therapeutic approach for dysplasia in IBD has not been established yet, and dedicated specialized endoscopists with interest in IBD are needed to fully investigate recent emerging techniques and technologies.

Traumatic anterior shoulder dislocation combined with scapular fracture in elderly patients is relatively rare. In this case, a patient visited Emergency Room of Dong-A University Hospital for shoulder pain after falling off a ladder. Radiographs demonstrated anterior shoulder dislocation with displaced Ideberg type IIb scapula (glenoid fossa) fracture combined with a large rotator cuff tear on magnetic resonance imaging. We performed arthroscopic rotator cuff repair, but a large fragment in the inferior glenoid was left untreated. At the 1 year follow-up visit, the pain visual analogue scale of the patient was 2, the American Shoulder and Elbow Society score was 88 and the patient had gained nearly full range of motion without any apprehension.

Ultrasound has been shown to be effective in the diagnosis of a variety of scrotal abnormalities. We performed ultrasound of the scrotum in 22 patients with conventional 3.75 MHz real time scanner. There were 6 intratesticular lesions-3 spermatic cord torsion, 1 malignant lymphoma,1 leukemic infiltration and l yolk sac tumor. Extratesticular abnormalities included acute epididymitis, chronic epididymitis, Tb epididymitis, epididymal cyst peritesticular abscess, spermatocele, hematocele and infected hydrocele. Sonography accurately distinguished between testicular and extratesticular masses in all cases and pathologic correlation were obtained for operated scrotal lesions. The results were as follows. l. Out of 22 patients, chief complaints of 9 were acute sctotum and 13 were scrotal mass. 2. Of 9 cases with acute scrotum, ultrasonography detected 5 cases with acute epididymitis, 3 cases with spermatic cord torsion and l case with hematocele. 3. Of 13 cases with scrotal mass, surgical exploration was done in 1O cases. 9 cases were confirmed same as post-operative finding (90% accuracy). One case with hematoma was confirmed to infected hydrocele after operation. 4. Ultrasound characteristics of 22 patients were classified as follows. 13 were hypoechoic, 4 were anechoic, 3 were mixed and 2 were hyperechoic.

In spite of prevalence of diphtheria, there were scant reports about immunity to diphtheria Korea. The Schick tests were done in the admitted patients to the pediatric department of the SUNH and in the children at the Bupyung area. Among the total children, 22.5% were Schick-positive. The positive rate of the patients of SUNH is 19.7%, which is different form that of the BuPyung children, i.e., 26.4%. The highest positive rate is in six to ten age group. The peak positive age at the SUNH patients is older than that of Bupyung Children. But there was no significant between two groups in eleven to fifteen age group. The positive rates of the primary &/or booster immunized group are much lower than that of the others. Among the nonimmunized 28 infants, 8 were Schick-positive. All of them are above 2m of age. The Positive rate of them imcreases they become older.
