Congenital synostosis of the proximal ends of the radius and ulna is a rare malformation which often completely prevents pronation and supination of the forearm. The evidence for a genetic etiology is provided by noting its presence in a Klinefelter's syndrome and its positive familial history. Two cases of congenital radioulnar synostosis occurred in brothers have been experienced and are to be reported with review of references.

Squamous cell carcinoma from the draining sinus of chronic osteomylitis has been recognized as a rare complication. The incidence of this complication is between 0.23% and 1.6% in cases of osteomyelitis. The cause of development of carcinoma at the site of chronic osteomyelitis is not well understood. This is a disease of middle aged men, and tibia is the most common site. Biopsy of squamous cell carcinoma which arises in the proliferating edge of the cutaneous ulcer and invades the bone, should include tissues from all sites of ulcer and bone marrow spaces. Histological diagnosis may be difficult because of preexisting metaplasia and pseudoepitheliomatous hyperplasia. Amputation at the adequate level is the treatment of choice. Four cases of squamous cell carcinoma involving tibia, metatarsal bone or calcaneus are reported with review of literatures.

A case of xanthogranulomatous oophoritis is presented in a patient who had a 3-month history of intrapelvic mass protruding into the vagina. The sonographic findings are a well defined mass shadowing lower echogenicity than the echo of the uterus at the posteosuperior aspect of the uterus. The CT findings are an enhancing solid mass with central necrosis containing a multiseptated cystic component.

In modem medical industries as in others, it has been emphasized by many experts such as Dr. Mayer and Dr. Donabedean that there should be quality assurance activities applying statistical knowledges in the processes of medical management and medical staff themselves for the better medical care and customer satisfaction. Three of our quality assurance programs for the purpose of shortening the treatment time In the department of emergency medicine in Keimyung University, Dong-San Medical Center had been carried out during the period of June 94 through December 95. Our methodology was mainly the process emphasized ; finding the causes of delaying factors in various processes related to the works of nurses, doctors, laboratory services, radiology services etc. in the emergency room, holding various meetings among the related groups with genuine discussions, notifying the new results in each step, encouraging the positive ones and also applying the new leadership technics. During the period of June 94 through December 95(for 1.5 years), the average E.R. patient treatment time from registrations to dispositions had been reduced by about 2 hours (from 5 hours 3 minutes to 2 hours 5 minutes) and its variations among the different specialities had been narrowed down to significant degree (p<0.05) revealing the preprogram base line standard deviation of 2.43 to 1.28 in post program through continuous quality assurance programs. It was also noted that the successful results of Q/A program have been closely related to the fact that the process should be designed and redesigned repeatly as needed and that all the participants related were actively involved in the planning and redesigning processes.

The magnetic resonance images (MRI) of 30 patients with surgically or biochemically confirmed pituitary adenomas (20 macroadenomas, 10 microadenomas) were retrospectively evaluated. Ten patients had hyperprolactinemia, another eight had acromegaly, another eight had nonfunctioning adenoma and four had Cashing disease. The examination were performed at a 1.5-T superconducting MR system using a multisection spin-echo technique with 3mm-thick sections and a 256×224 matrix. TI weighted sagittal and coronal images were obtained before and within 30 minutes after the administration of Gd-DTPA (0.1mmol/kg). Analysis of the MRI was focused on the signal intensity and enhamcement patterns of the pituitary adenoma before and after Gd-DTPA administration. Compared with endocrinologic diagnosis, macroadenoma showed heterogeneous enhacement in 55%, rim enhancement in 35% and homogeneous enhancement in 10%, Conclusively, the enhancement patterns of the pituitary adenoma did not correlate with the subtypes made according to hormone production.

As the incidence of acute myocardial infarction been increasing with prolongation of life spans, improvement in foods and life styles in Korea, rapid diagnosis and treatment is critical in survival of acute myocardial infarction patient. Most of the acute myocardial infarction result from atherosclerotic plaque forming thrombus and occlusion of coronary artery. Because early thrombolytic therapy is important to maintain the left ventricular function and survival rate, there have been many trials to reperfuse the occluded coronary artery. We have studied the many aspects of acute myocardial infarction such as sex, age, infarction site, chief complaints, change of ECG, change of serum enzyme, time delay on emergency room arrival, and compared the effectiveness of thrombolytic therapy. Total number of patient was 212, and males were 141(66.5%) and females were 71(33.5%). The most common infarction site was ant, fuel wall(102 cases,48%)of the heart and the most common chief complaint was chest pain(204 cases,97%). Among the 106 patients who received thrombolytic therapy, 101 patients(95%) had survived and 5 patients(5%) had died. Among the 64 patients who didn't receive thrombolytic therapy, 56 patients (87.5%) were alived and 8 patients(12.5%) were dead.

Secondary osteoarthritis of hip joints is a common disease and is frequently followed by chronic sublexation and dislocation. Twenty four case of the secondary osteoarthritis associated with chronic subluxation and dislocation of the hip joints were evaluated with plain radiography and computed tomography. We retrospectively analyzed 1) the ossification and calcification of the acetabular labrum, 2) the thickeness of the quadrilateral plate of the ilium, and 3) anteroposterior diameter of the acetabulum. The changes of the hip joints in subluxation (n=14) revealed ossification of the acetabular labrum in 12 cases (86%), thickening of the quadrilateral plate of the ilium in 11 cases (78%) but anteroposterior diameter of the acetabulum was not changed. The changes of the hip joints in dislocation (n=10) revealed no evidence of the ossification of the acetabular labrum, thickening of the quadrilateral plate of the ilium in 10 cases (100%) and decreased anteroposterior diameter of the acetabulum. We conclude that CT findings of subluxation and dislocation of the hip joints can be helpful in the evaluation of the secondary osteoarthritis of the hip joints.
