In order to identify the correlations between clinical results and quantitative data of gait analysis, we analyzed the results of 20 cases of total knee joint replacement arthroplasty in 15 patients with degenerative arthritis. We also evaluated the gait analysis of ten age-matched healthy candidates as a control group. Mean follow-up periods were 30 months. Clinical results included post-operative HSS (Hospital for Special Surgery) knee rating scores and the changes of the tibiofemoral angles. The three dimensional gait analysis included clinical assessment, video-taping, three dimensional kinematics and kinetics. The three dimensional kinematics were obtained using a 5 camera VICON system, and the three dimensional kinetic data was collected using two AMTI force plates. There was no statistical difference in linear parameters between the patient and control group. In patients group, however, double support time decreased as the HSS score increased, and range of knee motion and maximum knee flexion increased in accordance with the increase of pain score. Kinematic data of the patients group revealed that some parameters, such as knee flexion during loading response, knee flexion in swing phase, and knee varus during swing phase, were decreased. On the other hand, internal rotation of the knee from initial contact to initial swing was increased when compared with that of control group. There was no significant correlation between the degrees of tibiofemoral angle and coronal plane moment in the patients group. In three cases which showed mild varus instability post-operatively, knee flexion during loading response decreased and valgus moment in midstance increased as compared with the cases without instability. We believe that three dimensional gait analysis will be a good modality for evaluation of the results after total knee arthroplasty. With further accumulation of long term. follow-up data of gait analysis, we might be able to predict the long term results of total knee arthroplasty including possibility of loosening.

The incidence of Congenital diaphragmatic hernia is 1 in 2000-5000 live births and hiatal hernia is even rarer especially in neonates. We experienced a case of congenital hiatal hernia (mixed type) in a week old female. Upon confirmation of the diagnosis, the surgery was done. Through the right thoracotomy, Belsey-Mark IV fundoplication was performed after the reduction of herniated viscera. The patient was fed 3 days after operation. there has been no complaint for 6 months after discharge. Therefore, we present this case with overall review of the literature.

Children with abnormal sex development may present with ambiguous genitalia in the newborn period or lacking of secondary sexual characteristics in puberty. Clinicians should make a prompt and accurate diagnosis and counsel parents on therapeutic options to minimize or avoid medical and psychological complications. 5alpha-reductase deficiency is a rare autosomal recessive disorder of sex development caused by a mutation of the 5alpha-reductase type 2 gene. As a result, there is an abnormality in conversion of testosterone (T) to dihydrotestosterone (DHT) and children with 5alpha-reductase deficiency are born with ambiguous genitalia. Here, we report identical twins who presented with ambiguous genitalia with a 46,XY karyotype and were diagnosed as 5alpha-reductase deficiency.

In order to examine the neurotoxic mechanism of oxygen radicals on cultured bovine oligodendrocytes, cytoxic effect of oxygen radicals was examined when cultures were treated with various concentrations of xanthine oxidase (XO) and hypoxanthine (HX) in culture medium. In addition, the neuroprotective effect of iron-chelators against the neurotoxicity induced by oxygen radicals was evaluated by MTT assay. Cell viability was remarkably decreased in a time-dependent manner after exposure of cultured bovine oligodendrocytes to 20mU/ml XO and 0.1mM HX for 4 hours. In the neuroprotective effect of iron-chelators on oxidant-induced neurotoxicity, tetrakis (2-pyridylmethyl)ethylenediamine (TPEN) blocked the neurotoxicity induced by oxygen radicals, while DFX was not effective in blocking oxidant-induced neurotoxicity in these cultures. These results suggest that oxygen radicals are toxic in cultured bovine oligodendrocytes, and also selective iron-chelators such as TPEN are effective in blocking the neurotoxicity induced by oxygen radicals.

Three cases of synchronous carcinomas of endometrium-fallopian tube, endometrium-cervix and endometrium-ovary are reported. Case 1 is endometrial endometrioid adenocarcinoma with FIGO stageIb, Grade 2 and tubal serous adenocarcinoma with FIGO stage Ib, Grade 2. Case 2 is endometrial serous carcinoma with FIGO stage Ilb and squamous cell carcinoma with FIGO stage Ial. Case 3 is endometrial endometrioid adenocarcinoma with FIGO stage Ia, Grade 1 and ovarian mucinous adenocarcinoma with FIGO stage IIIa, Grade 2. There is much confroversy with respect to staging and management of such cases since these tumors may represent either two synchronously occuring primaries or single primary with metastases. It is suggested that when each tumor is different histological subtype the tumors may be considered as two separate primaries and treatment may be less aggressive. It may be a favorable prognosis. The authors present three cases of synchronous carcinomas with a review of literature.

The present study was performed to evaluate the effect of Tetracycline-HCl on the change of implant surface microstructure according to application time. Anodic oxidation surface were utilized. Implant surface was rubbed with 50mg/ml Tetracycline-HCl solution for 1/2min., 1min., 1 1/2min., 2min., 2 1/2min. and 3min. respectively in the test group. Then, specimens were processed for Ra Value test and scanning electron microscopic observation. The results of this study were as follows. 1. The anodic oxidation surface roughness tests don't show significant difference on conditioning with saline and Tetracycline-HCl. 2. The anodic oxidized surfaces showed the craterous structures. The surface conditioning with Tetracycline-HCl didn't influence on its micro-morphology. In conclusion, Anodic oxidation implant surface is stable to detoxificate with 50mg/ml Tetracycline-HCl of implant surface.
