The purpose of this study was to investigate the causes of food impaction and to explore solutions as well. For this study, 39 patients with food impaction wee selected. 77 contact areas in these patients were investigated mobility, tightness of contact area, gingival index, plaque index, attachment loss, alveolar bone loss, proximal caries, marginal ridge distance and occlusal relationships. The results were as follows ; 1. Teeth without distal support were found to be the most frequent site of food impaction (41.6%). Food impaction was found to be more frequent in the upper teeth (66.2%) than the lower teeth (33.8%). 2. Food impaction was found in tight contact cases (71.4%). Alveolar bone loss was not found in the early stage of food impaction (83.1%) 3. The distance between the marginal ridges of food impaction sites (mean=0.48mm) was shorter than that of the control group. (mean=0.77mm) (p<0.001) 4. In 18.2% of t he cases, proximal carries were found at the food impaction site. 5. Food impaction affected patient's occlusion with the following frequencies ; cusp to marginal ridge relationship (72.7%), cusp to fossa relationship (3.9%) and stepped relationship (23.4%).

PURPOSE: This study was performed to compare the radiographic results of femoral tunnels made through the tibial tunnel and through the anteromedial portal. MATERIALS AND METHODS: From March 1996 to September 1997, fifty-five reconstructions of anterior cruciate ligament were performed. Group I (femoral tunnel through tibial tunnel) was composed of 30 cases and group II (femoral tunnel through anteromedial portal) was consisted 25 cases. On postoperative anteroposterior and lateral radiographs of knees, five angles were measured : APD/LD (angle between longitudinal axis of femoral bone block of patella tendon bone graft and that of interference screw in anteroposterior view/ lateral view), AFT (the angle between longitudinal axis of femoral tunnel and that of tibial tunnel in anteroposterior view), APFT/LFT (the angle between longitudinal axis of femoral tunnel and that of femoral shaft in anteroposterior view/ lateral view) and the graft tunnel mismatch was evaluated. RESULTS: Average APD was 1.30+/-3.13 degree in group I and 0.52+/-1.85 degree in group II (P>0.05), average LD was 4.97+/-7.62 degree and 1.48+/-3.30 degree (P<0,05), average AFT was 12.40+/-7.29 degree and 19.48+/-8.49 degree (P<0.05), average APFT was 15.33+/-6.95 degree and 14.32+/-7.33 degree (P>0.05), and average LFT was 36.57+/-5.20 degree and 39.64+/-6.48 degree (P>0.05), respectively. CONCLUSIONS: We concluded that making a femoral tunnel through the anteromedial portal decreased the divergence between the femoral interference screw and femoral bone block of patella tendon-bone autograft.

Interleukin-6(IL-6) is a multifunctional cytokine, and deregulated IL-6 gene expression has been implicated as being involved in the pathogenesis of a number of diseaaes. So we measured the serum level of IL-6 to find a relationahip between uterine cervical cancer and serum IL-6 level. The serum levels of IL-6 were meesured m 54 patients adrnitted to the Severance hospital, from August, 1992 to February, 1993, of whom 27 patients were diagnosed as invasive cancer of cervix, 17 as CIN, and also utilizing 10 patiente diagnosed as uterine myoma as a control group for matched age and parity. The average serum level of IL-6 in invasive cancer, CIN, and uterine myoma were respectively 30.33pg/ml, 37.27pg/ml, and 12.45pg Jml. In 22% af cervical cancer patients (6 of 27), and 27% of CIN patients (4 of 17) studied blood levels of II-6 were detected whereas only 10% of uterine myoma (1 of 10) shorved the same result. However, the difference does not seem to be statistically significant, There was no statistically significant difference among any of the groups, and age and stage did not show any significant cmrelation, and the results need furt,ber investigations.

Generalized plane xanthoma is less common and usually involves the eyelids, lateral side of the neck, upper trunk, and extremities. Lesions, however, may appear on any portion of the body. Cutaneous xanthomas may occur in hyperlipidemic and in normolipidemic states. Generalized normolipidemic plane xanthoma is often associated with multiple myeloma, other reticulo-endothelial malignancies and monoclonal gammopathy with unknown significance(MGUS). We wish to report two eases of generalized plane xanthoma associated with IgG monoclonal gammopathy of unknown significance.

Ganglioneruroblastoma and neuroblastoma are among commonest types of childhood malignancy and a number of unique paraneoplastic syndromes have associated with both localized and disseminated neuroblastoma. The coincidence of neuroblastoma and myoclonic encephalopathy or other paraneoplastic syndromes occurs relatively rare, and therefore, failure to recognize this association could result in delays in both diagnosis and treatment, and the result could prove to be unfortunately fatal. The mechanism which underlies the remote damaging effect of neural crest tumor, especially neuroblastoma, on the nervous system resulting in myoclonic encephalopathy is by no means clear. In addition the nature and the extent of the pathologic lesion are inconsistent. We experienced a case of myoclonic encephalopathy associated with an occult mediastinal ganglioneuroblastoma in a 22-month-old girl who was hospitalized for inability to walk without support and tilting of the head to the left side. She became increasingly ataxic, and during the hospitalization myoclonic jerks of upper extremities and head along with chaotic, rapidly flickering, multidirectional spontaneous eye movements, were noted. Laboratory data included normal complete blood count, urinalysis, BUN and creatinine, electrolytes and bone marrow. Chest X-ray and chest CT revealed a relatively well marginated right posterior mediastinal mass. In a 24 hours urine excretion test, VMA and catecholamines were increased. Over the next 2 weeks, a surgical exploration revealed a right posterior mediastinal mass. Microscopically the mass proved to be a ganglioneuroblastoma, extending to right innominate artery and right axillary lymph nodes. Within 2 weeks after the surgery, radiotherapy (2,400 rads) and chemotherapy (CTX, DTIC, VCR) were started, but corticosteroid was not used. She has been free of tumor and abnormal neurological systemic symptoms and signs for 1 1/2 year since the completion of chemotherapy. In the 3 1/2 years follow-up period, her neurologic symptoms has completely resolved by the completion of 2 years chemotherapy. We report a case of mycoclonic encephalopathy associated with hidden ganglioneuroblastoma in 22-month-old girl.

This study was undertaken for the clinical analysis and evaluation on 121 patients with incompetent internal os of the cervix, who were admitted and treated with McDonald operation or Shirodkar operation at the Soonchounhyang Medical Center from January 1991 to December 1995. The results of this study were as follows : 1. The incidence of this IIOC was 1.1% of 11,116 cases of total delivery. 2. The mean age of IIOC was 31.7 years old. 3. The average number of gravida was 3.2. 4. The most common contributary factor was previous history of artificial abortion (51.2 %), and midtrimester abortion (17.4 %), cervical laceration due to previous vaginal delivery (8.3 %) etc. was followed. 5. The success rate of operation was 76 %, and the highest success rate (85.7 %) was reveald with period from 15th weeks to 16th weeks of gestation. 6. When cervical dilatation was abscent or small, the success rate of operation was high. 7. The factors of failed operation were preterm labor (58.7 %), PROM (34.5 %), and PIH, bleeding. 8. The delivery method after operation was vaginal delivery in 83 cases (68.6%) and cesarean section in 38 cases (31.4 %).
