Supracondylar Fractures of the femur are not as cammon as femoral neck or intertrochanteric fractures, but their treatment may be just as difficult. Few surgeons have had extensive experience with this complex fractures of uncommon frequency. Until a few years ago, conservative treatment was considered superior to internal fixation of supracondylar fractures of the femur in adults. However, the development of new fixation devices and techniques has, according to several investigations, improved the results of the treatment of these fractures. The following clinical results were shown by analysis of 27 cases of femoral supracondylar fractures experienced in the Department of Orthopedic Surgery, Capital Armed Forces General Hospital in the past 3 years from Jan. 1977 to Oec. 1979. 1. The most common cause of these fractures were traffic accidents. 2. Of 27 cases, 11 cases were treated by conservative method, 16 cases were treated by open reduction and internal fixation. 3. Anatomical reduction and rigid internal fixation led to 80% of good to excellent results whereas only 33.4% of good to excellent results were obtained in patients in whom the fixation was not absolutely rigid. 4. In the treatment of supracondylar fractures of the femur, anatomical reduction and rigid internal fixation (80% of good to excellent results) resulted in better functional recovery after union of fractures than conservative treatment (45.5%).

PURPOSE: To evaluate the role of CT in early detection, location, and extent of osteochondritis dissecans (OCD) of the elbow joint. MATERIALS AND METHODS: We reviewed surgically proved 27 cases of 22 patients with osteochondritis dissecans in elbow joint retrospectively. We compared simple x-ray(elbow AP & lateral) with CT on the basis of staging of OCD of talus by simple x-ray. RESULTS: The frequency of location was as follows:fourteen cases of capitellum, 5 cases of olecranon tip, 5 cases of medial epicondyle, 2 cases of trochlea, and 1 case of olecranon base. Among the 4 cases of normal finding on simple x-ray, CT showed 1 case each of stage I, II, III, and IV OCD and among the 8 cases of stage I on simple x-ray, CT showed 2 cases of stage I, 1 case of stage II, and 5 cases of stage III. Among the 3 cases of stage II on simple x-ray, CT showed 1 case of stage II and 2 cases of stage III. Among the 5 cases of stage III on simple x-ray, CT showed 1 case of stage II, 2 cases of stage III, and 2 cases of stage IV, but it was difficult to detect the presence or absence of attachment between the articular cartilage of mother bone and osteochondral fragment. CT was more accurate than simple x-ray in detection of loose body. CONCLUSION: CT might be an useful imaging modality in early diagnosis of OCD and evaluation of its anatomic location and extent in elbow joint.

PURPOSE: To evaluate and compare the diagnostic findings and usefulness of MRI and MR arthrogram in recurrent anterior dislocation of the shoulder. MATERIALS AND METHODS: MRI and MR arthrogram of thirty-two cases of thirty patients with recurrent anterior dislocation of the shoulder were retrospectively analyzed to evaluate glenohumeral ligaments, pattern of labral injury, bony Bankart lesion, capsular stripping, Hill-Sachs lesion, and loose body. RESULTS: Labral abnormalities was detected on MRI in 23 cases(72%) and MR arthrogram in 22 cases(69%) as labral tear, detachment, and deficiency. All cases involved anteroinferior labrum. On MR arthrogram, labral abnormalities was confined to anteroinferior portion in 4 cases(18%), extended into midglenoid level in 13 cases(59%), and that into anterosuperior portion in 5 cases(23%). Capsular stripping was noted on MRI in 6 cases(19%) and MR arthrogram in 12 cases(38%). Loose body was detected only on MR arthrogram in 5 cases (16%). Bony Bankart lesion and Hill-Sachs lesion was detected equally on MRI and MR arthrogram in 2 cases (6%) and 21 cases(66%) respectively. We obtained identical findings on both MR arthrogram and operation field in 6 patients. CONCLUSION: MRI with its excellent soft tissue contrast resolution and multiplanar imaging capafility helps detection of labral injury in recurrent anterior dislocation of the shoulder. MR arthrogram is slightly invasive, but shows good artatomic details of labral-ligamentous-capsular relationship and thus provides accurate detec- tion of pattern of labral injury, capsular stripping, and loose body.

Low-grade nasopharyngeal papillary adenocarcinoma is an unusual nasopharyngeal tumor. This malignant tumor originates in the epithelium and exhibits adenocarcinomatous differentiation and indolent behavior. Macroscopically, these tumors are pedunculated polypoid masses that arise on the roof of the nasopharynx. Microscopically, they are characterized by papillary and glandular epithelial proliferation. We report a case of a 25-year-old woman who presented with a papillary adenocarcinoma on the roof of nasopharynx; in describing the case, we have focused on the histological features and endoscopic management of the tumor. The tumor was completely excised via nasal endoscopic approach. Immunohistochemical analysis of the tumor was performed based on a differential diagnosis of metastatic papillary thyroid carcinoma. The testing involved thyroid transcription factor-1, thyroglobulin, and epithelial membrane antigen analysis. The patient remained disease-free for over 6 months after the surgical excision performed via nasal endoscopic approach.

OBJECTIVE: To investigate the expression of apoptosis related proteins and apoptotic cells on the human ovarian follicles. MATERIALS AND METHODS: Thirty five Formalin-fixed paraffin-embedded human ovarian tissue blocks were selected from the surgical pathology files of the department of pathology, College of Medicine, Yonsei University, for the period from 1996 to 1998. All specimen were from premenopausal women aged from 32~45. Ovarian tissues were collected from the patients performing hysterectomy for benign uterine diseases. Immunohistochemical staining was performed for the detection of DNA fragmented cell, Bcl-2, Bax, Fas and Fas-ligand. RESULTS: Bcl-2 and bax were not expressed on the surrounding cells and oocyte of the primary, primordial and preantral follicles. Fas and Fas-ligand (Fas-L) were not expressed on the surrounding cells on the primordial and primary follicles. But expressed on the surrounding granulosa cells and oocyte in the primordial and primary follicles. In the healthy follicles, Bcl-2 was expressed on the granulosa cells, however, Bax was not expressed. DNA fragmented cells were expressed on the inner granulosa cell layer of atretic follicles. CONCLUSION: Fas, Fas-ligand, and Bax may be responsible for the follicular atresia and Bcl-2 may be involved in the follicular survival in the human ovary.

Pheochromocytoma is one of the surgically curable hypertensive syndrome and may arise wherever chromaffin cells are located. A case of a left large adrenal pheochromocytoma developed in a 49 year old male is presented with brief review of literatures.
