The bipolar hemiarthroplasty is one of the treatment methods of the avascular necrosis of the femoral head and the fracture of the femur neck. The mechanism of bipolar hemiarthroplasty is intended to distribute the forces at the site of the inner and outer articulation, and theoritically diminish acetabular wear and produce a painless arthroplasty. The authors analyzed motion of two components in 23 cases of the bipolar hemiarthroplasty, performed at the Department of Orthopaedic Surgery, Korea University Hospital, between January, 1985 and January, 1993 with average 47 months follow up(range 24 to 84 months). The results obtained were as follows: 1. In the motion of the two components, inner bearing motion was average 11.5 degrees(from 1 to 29 degrees) and outer bearing motion was average 21.4 degrees(from 3 to 45 degrees). 2. The inner bearing motion was highest at 12 months with average 16 degrees and outer bearing motion was lowest during the same period with average 15 degrees. During the follow up the inner bearing motion was decreased whereas outer bearing motion was increased. 3. The inner or outer bearing motion of bipolar component was no correlation with age, sex and clinical result.

This study was undertaken at the department of Obstetrics and Gynecology, Chonnam University Medical School, to investigate the association between some of the risk factor and the incidence of intrauterine fetal growth restriction(IUGR). The studied population was selected from patients who admitted at Chonnam University Hospital during January, 1992 through May, 1997, with following criteria, Korean, singletone pregnancy with live birth and known gestational weeks with 28 or more. And then, the risk factors were analyzed in terms of maternal factor, placental factor, and fetal factor. The following results were obtained. 1) The incidence of IUGR was 6.1%. 2) The incidence of IUGR was higher at young aged mother and nullipara. 3) Only 39.1% of etiologic factors for IUGR was found to have known causes. According to the risk factors for IUGR, hypertensive disorder during pregnancy, anemia, cardiac disease, leukemia, and pulmonary tuberculosis were associated with increased incidence of IUGR. 4) The relative risk of IUGR was much higher in neonates born with congenital anomalies. 5) According to the placental causes of IUGR, placenta previa and placenta abruption showed some association with IUGR.

Although the incidence of the Penicillium keratitis increases, there is no available reports from the literature. Dense, gray-whitish infiltration combined with ulceration was observed at the central cornea of 62-y-o-man. Hypopyon was observed also. Colonies on Sabouraud's agar showed light violet pigmentation. On the light microscopic examination of the recipicent cornea after penetrating keratoplasty, proliferation of the fungal hyphae in the deep corneal stroma was observed, but collagen fibers of the superficial stroma were re-formed over the necrotic stromal tissue. Electron microscopy showed a hiypha with triple cell wall.

In order to evaluate the effect of fluconazole on Candida albicans induced keratitis, an experimental study was conducted on 30 rabbits. After 4 days of inoculation with Candida albicans on rabbit cornea, animals were divided into three treatment groups: daily treatment with a single oral dose of 50mg fluconazole(group 1); topical therapy with 0.3% fluconazole solution 6 times a day(group 2); control animals without any medical treatment(group 3). The rabbits were treated for 28 days following completion of Candida albicans inoculation, and the severity of keratitis was examined with a slit lamp biomicroscope every two days throughout the treatment period. After the treatment, animals were sacrified and histopathological study of the corneas were per formed. Animals in group 1 and 2 showed significant improvements in keratitis compared to that of control animals beginning 10 days of treatment(p<0.05). No statistically significant difference between the group 1 and group 2 were noted in response to treatment(p>0.05). Thus, we suggest that fluconazole is effective in treatment of keratitis induced by Candida albicans.

The current paper reports on a case of subdural empyema secondary to frontal sinusitis in an otherwise healthy child. Sinusitis is a common and benign condition in most pediatric cases. Because of the widespread use of antibiotics, intracranial extension of pediatric sinusitis is rarely seen today; however, complications (e.g., cavernous sinus thrombosis, orbital infection, meningitis, and subdural empyema) are potentially life threatening. A 15-year-old right-handed male presented with a 3-day history of fever, headache, and left-sided palsy. Computed tomography revealed right-sided subdural empyema with right frontal sinusitis and maxillary sinusitis. A postoperative inpatient neurological consultation was requested 2 months post-surgery due to motor function deficits. The results suggested that early and accurate diagnosis of subdural empyema leads to prompt treatment and a favorable outcome for the patient.

SUMMARY: The present study was carried out to evaluate whether the coculture system of human embryos with Vero cells can improve the quality of embryo or overcome the repetitive implantation failures in order to obtain pregnancy. From January to December 1996, a total 202 cases which patients with the problems of repetitive implantation failures (group I) or those with the poor embryonic quality in their previous cycles (group II) was analysed. The quality of cocultured embryo, pregnancy, on-going and implantation rates between coculture and control groups were compared. Of 93 cases in group I, coculture was performed in 34 cases and conventional IVF for the rest. Of 109 cases in group II, 36 for coculture and 73 for conventional IVF. In group I, pregnancy, on-going and implantation rates in coculture group (14/34 (41.2%), 9/34 (26.5%), 16/81 (19.8%), respectively) were higher than those of control (11/59 (18.6%), 8/59 (13.6%), 12/152 (7.9%), respectively). There is significance in the pregnancy and implantation rates (p=0.028 and p=0.015). In group II, pregnancy, on-going and implantation rates in coculture group (8/36 (22.2%), 5/36 (13.9%), 8/87 (9.2%), respectively) were higher than those of control (5/73 (6.8%), 3/73 (4.1%), 3/158 (1.9%), respectively). Like the result of group 1, there is significance in the pregnancy and implantation rates (p=0.028 and p=0.022). Coculture system with Vero cells works well in the groups of the two indications. Although the case of 3 day-coculture was small as 15 cases in group II, 3 day-coculture improved pregnancy rate (4/15 (26.7%)). Therefore, 3 day-coculture with assisted hatching is recommended to the patients with poor embryonic quality. In conclusion, coculture system with Vero cells can be suggested as an effective method which improves pregnancy rate in those who have repetitive implantation failures or whose embryonic quality was poor in their previous cycles.
