1.A Case of Giant Sertoli-Leydig Cell Tumor of the Ovary with Masculinization.
Korean Journal of Gynecologic Oncology and Colposcopy 2001;12(1):63-67
Sertoli-Leydig cell tumor is a rare sex-cord stromal tumor of the ovary and accounts for less than 0.5% of all ovarian tumors. It is among the most fascinating from pathologic and clinical viewpoints in masculinization. We experience an unusual case of a poorly differentiated Sertoli-Leydig cell tumor in 60-year-old woman who showed masculinization and present it with brief review of literature.

The purposes of this clinical study are to observe the clinical findings of the high lumbar disc herniation, to analyze the of the posterior approach and to define the surgical indications of the high lumbar disc herniation. We analyzed the 13 cases which were treated at the Deparment of the Orthopaedic Surgery, National Medical Center from March 1988 to December 1992(Mean follow up rate : 17. 2 months). 1. We operated 10 cases by posterior approach and 1 case by anterior approach due to marked degenerative osteophyte. 2. We evaluated the post-operative results by modified Macnab criteria, the 2 cases showed no symptomatic improvement because of respectively associated high lumbar osteophyte and lower lumbar spinal stenosis. 3. On conclusion, suspicion is important in cases of incompatible clinical symptoms and signs of the intervertebral disc herniation. MRI is the most recommended diagnostic tool, because it can provide the high lumbar levels with saggital section image and differentiate herniation from degenerative osteophyte. As for the surgical indications of high lumbar disc herniations, we suggest marked dural compression by disc or sequestered disc materials in MRI, definite neurological complications such as ankle clonus, increased DTR, weakness of quadriceps and hip flexor muscle and severe radiating pain on the anterior thigh. We recommended the posterior approach for the surgical intervention of high lumbar disc herniation except cases marked degenerative osteophytes.

This study was undertaken to investigate mineral changes in weathered scalp hair after burial. EDX (energy dispersive X-ray spectroscopy) analysis was performed to measure the presence of minerals on the hair surface. Twelve scalp hairs, buried for 5-40 years, were chosen from deceased individuals buried in tombs in Soha-Ri, Kyonggi-Do, and other regions in Korea. Three normal hairs were used as the control group. EDX data showed that carbon, oxygen, and sulfur were detected in hair collected from all three burial grounds. In contrast, calcium was only detected in hair collected from tombs in Soha-ri. The amounts of calcium and sulfur were found to decrease with time for hair collected from tombs in Soha-ri. Similar results were observed with sodium for hair collected from other regions. These results show region specific mineral detection and a decrease in the concentration of minerals with time. Consequently, it is suggested that changes in minerals concentration in weathered hair could be used as basic data in the field of forensic medicine.

The transpedicular screw fixation is known to be capable of providing more secure correctional, force and rigid fixation to the spine. But it is often accompanied by various complications, including stress shield effects, loosening in osteoporotic spine, pseudoarthrosis, hardware problems and long-term change in motion behaviors at the adjacent motion segment and etc. The purpose of this study is to compare the flexible and rigid rods system in terms of complications and problems for various degenerative lumbar diseases. From September 1991 to November 1994, 41 patients were operated with the flexible rods system (group A) and 39 patients with the rigid rods system (group B). They were followed up for more than 4 years. The flexible rods system was composed of 41 cases of Wiltse system and the rigid rods system was composed of 29 cases of Diapason, 8 cases of TSRH and 2 cases of CD instrument. The resuits of the study were as follows: 1. By standard Cobb lateral measurement, 7 cases in group A and 10 cases in group B showed significant loss of sagittal angle (>4), post-operatively. 2. Hardware failure was noted in 7 cases in group A and 10 cases in group B. In group A, rod bending was seen in 4 cases, rod breakage in 2 and screw loosening in one. In group B, screw loosening was observed in 5 and screw-rod locking mechanism failure in 5 cases. 3. In spondylolisthesis patients, 10 cases in group A and 14 in group B, there was no statistically significant differences between the two groups in the reduction rate immediately after surgery and loss of reduction at the last follow up. 4. Clinical results were good to excellent in 85.4% of patients in group A and 82.1% of group B. No statistically significant differences between the two groups were found, 5. No statistically significant differences between the two groups were found with respect to degenerative changes at the adjacent motion segment to the fused level and pseudoarthrosis.

One of the commonest and most serious problems of the injured hand is flexion contractures of the fingers. Such deformities not only functionally impair the digit, but also reduce or restrict the functional capability of the entire hand. We reviewed 150 digits of 73 patients with flexion contractures of the fingers which had been treated at National Medical Center from Jan. 1976 to Dec. 1985. The results were as follows: 1. The duration of flexion contractures which were scattered from 4 months to 17 years and average duration of contracture was 20.6 months. 2. The methods of treatment were Z-plasty, adhesiolysis, capsulotomy, excision of both collateral ligaments, stripping of extensor mechanism and volar plate and release of flexor tendon sheath according to injury mechanism and duration of contracture. 3. The postoperative results showed up 32 (21.3%) excellent, 78 (52%) good, 24 (16%) fair and 16 (10.7%) poor. 4. The postoperative results of burned injury which showed up-8 excellent, 11 good out of 20 cases they are supposed to have satisfactory results. 5. Crushing injury which had intraarticular fracture or comminution show up unsatisfactory results. 6. It seems obvious that the early active motion of interphalangeal joint is important to improve joint function. 7. The arc of motion was retained in a more functional position postoperatively than preoperatively.

In the treatment of elderly hip fracture, early mobilization as a means of reducing early postoperative morbiyt and morbidity is mandatory. Even though Ender nailing have many advantages, most serious problems with use of Ender nailing method are distal migration of nails, subsequent loss of fixation and limited knee joint motion. To prevent these difficult problems, we have used distal wiring technique with Ender nailing since 1988. In operation, we performed Ender nailing as usual manner under image intensifier and for the prevention of the nail migration, we performed circumferential wiring through the each Ender nail eye and above the adducter tubercle of the distal femur. Forty six cases were available with minimum follow-up of six months which were healed radiologically and clinically (Mean follow up: 21 months). The mean age was 74 years (Range: 52 years-88 years)and showed 26 cases of famale and 20 cases of male. The radiological morphometry using Singh index showed poor bone quality: 36 cases were below Grade III and the fracture type was classified by Tronzo criteria. In results, patients who had Ender nailing with distal wiring showed no distal migration, however one case of proximal migration was observed at the beginning stage of this technique. So, in elderly trochanteric fracture, to reduce the complication of the Ender nailing, especially nail migration, the authors recommend the Ender Nailing with distal wiring technique.

Pneumocystis carinii is a pulmonary pathogen of immunocompromised humans or other mammals. Its infection results from activation of organisms involved in latent infection or from new infection through the air. Almost all children are known to be infected within 2 to 4 years of birth, though prenatal transplacental transmission has not yet been demonstrated. In this study we observed experimental P. carinii infection in neonatal rats, thus investigating the possibility of transplacental vertical transmission by Diff-Quik staining of the lung impression smears and in-situ hybridization for lung sections. The positive rate of P. carinii infection in immunosuppressed maternal rats was 100%, but that in normal maternal rats was 0%. Cystic forms of P. carinii were observed in three of six 1-week old neonatal rats born of heavily infected mothers, but none of them was positive by in-situ hybridization. Five weeks after birth, cystic forms were detected in four neonatal rats. In the lobes of the lungs, no predilection site of P. carinii was recognized. Counts of cystic forms on smears and the reactivity of in-situ hybridization in the lungs of neonatal rats were significantly lower than in maternal rats. The present findings suggest that P. carinii is rarely transmitted through the placenta and proliferates less successfully in the lungs of neonatal rats than in mothers.
