Despite the continually improving results of total knee arthroplasty, infection remains the most debilitating complication. The treatments of infected total knee arthroplasty were variable, but initially we removed infected implants and inserted antibiotic containing cemented spacer. Postoperatively, patients were mobilized in a 30 knee flexion state and treated with parenteral antibiotics. After control of infection was clinically and radiologically determined, we inserted PCL substitute total knee prosthesis. Five days postoperatively, patient began touch down standing exercise. We observed two cases in whom infected total knee arthroplasty had been salvaged successfully with two-stage implantation using cement spacers containing antibiotics.

Purpose: The goal of study was to evaluate the clinical and radiographic performance of the proximal modular cementless femoral stem for use in revision total hip arthroplasty. Material and method: Fifty seven patients (57 hips) were followed for longer than 24 months or up to 8.4 years after performing revision total hip arthroplasty with using the proximal modular cementless femoral stem between January 1997 and December 2002. The preoperative diagnosis included 45 cases of aseptic loosening, 5 cases of septic loosening (re-revision operation), 6 cases of periprosthetic fracture and 1 case of recurrent dislocation. The bone deficiencies were classified according to the Paprosky classification: there were 27 cases of Type I and II, 19 cases of Type IIIA, 9 cases of Type IIIB and 2 cases of Type IV. Results: The average Harris hip score improved from 47 to 87.6. Clinically satisfactory results were noted in 50 patients (87.7%). Radiographically, distal stable fixation was observed in 54 patients (94.7%). Intraoperative complications included two greater trochanteric fractures and two proximal femur fractures. Postoperative complications included 5 femoral stem subsidences (2hips< 5mm, 3 hips>20mm), 4 deep infections, 2 non-unions of the greater trochanter and the osteotomy site and set screw dissociation was noted in 1 case. 5 proximal component changes were done due to progressive subsidence in two cases, non-union at the osteotomy site and trochanteric displacement in two cases and set screw dissociation in one hip. For the infection cases, the proximal segment was removed and re-revised with a 2nd stage operation. (Ed note: check this.) The subsidence of the femoral stems was showed in 3 Paprosky grade IIIA cases and in 2 cases of grade IIIB or more. There was no postoperative periprosthetic fracture observed at the last follow-up. Conclusion: Revision total hip arthroplasty using the proximal modular cementless femoral stem showed good results in the face of the infection of the proximal component and deficient proximal bony support. This procedure appears to be convenient for the surgeon to correct anteversion of the femoral head and leg length discrepancy.

Intra-abdominal desmoplastic small round cell tumor has been described in the literature since 1989. It is characterized by the occurrence in ages less than 40 with male predominance, an intra-abdominal location, and small round to oval shaped tumor cells with divergent differentiation in the background of the desmoplastic stroma. We recently experienced this tumor in an inguinal lymph node of a 36-year-old man. It is suspected that it metastasized from a lower intra-abdominal tumor. Immunohistochemical stains for keratin, epithelial membrane antigen, vimentin, S-100 protein and neuron specific enolase were positive. This is the first documented case in Korea. Herein, we report on this tumor with a review of literature.

BACKGROUND: Using c-fos expression one of the immediate early gene, as a marker of altered neuronal response, we investigated the effect of superior cervical ganglion block (SCGB) exhibiting the same effect of SGB of human on the activity of several brain regions which are considered as located on autonomic neural pathway and neuroendocrine axis in rat. METHOD: The 48 Sprague-Dawley strain rats were divided into 4 groups, as saline/stress (control) group, SCGB/stress (tested) group, saline group, SCGB group. Superior cervical ganglion block was conducted in the SCGB/stress group and SCGB group while saline/stress and saline group were sham operated. After then restraint stress was imposed on the animals of SCGB/stress group and saline/stress group. And 2 hour after injection (saline, SCGB group) or restraint stress (saline/stress, SCGB/stress group), c-fos protein (Fos) was localized by immunocytochemistry. RESULTS: Much stronger Fos immunoreactivity was induced in the several brain region of control group rats compared to other three groups and the numbers of Fos positive cell count of tested group were significantly decreased in paraventricular hypothalamic nucleus (p<0.01), A5 (p<0.01), raphe pallidus (p<0.05), nucleus tractus solitaius (p<0.01) compared to control group. CONCLUSION: This study demonstrate that superior cervical ganglion block attenuates stress induced neuronal activities of paraventricular hypothalamic nucleus, A5, raphe pallidus, nucleus tractus solitarius.

The incidence of diphtheria is markedly decreased in the developed countries. But in Korea, since 1970, there has been an increased incidene of diphtheria and some clinical modifications of the classical picture were seen, such as less incidence of preudomembrane, milder constitutional symptoms and fewer positive culture of C. diphtheriae. With this in mind we reviewed the 40 cases of diphtheria, who were admitted to Ped. Dept. of PMMC during the period of past 5 years period(Feb. 1972-Dec. 1976). Thus this study is based on the clinical manifestations, the findings of routine lab. And EKG, localization of diphtheric lesions, relationship between the first visit to hospital and death rate, and the various complications of the disease esp. toxic myocarditis. The results of this study are as follow: 1. Number of patients had been increased since 1974. The 70% of diphtheric cases was developed in Winter season. 2. The age incidence was highest in the 4~8 years range and 14 cases (35%) were before 6 years of age. The sex ratio of male to female was 1.5:1. Primary DPT vaccination had been done in only 1 case. 3. The average time coming to the hospital was 5.4 days of illness. Patients with laryngeal type visited hospital earlier than patients with pharyngeal type. 4. The site of localization of diphtheria was larynx (42.5%), pharynx (37.5%), and pharyngolarynx (20%). 5. The chief clinical findings on admission was dyspnea (70%), fever (67.5%) and pseudomembrane (30%). There were marked difference in clinical manifestations with the site of localization of the disease. 6. Leucocytosis was found in almost every case. Culture studies for Corynebacterium diphtheriae were positive in 72.5% of cases. 7. The order of EKG abnormalities were S-T segment and T-wavechanges, complete A-V block, A-V dissociation, P-R interval prolongation, and right bundle branch block. 8. Complications of the disease were as follows : Bull neck (20%), myocarditis (30%), peumonia (27.5%), and proteinuria (42.5%). 9. Mortality rate was 15% of the total, 20% in pharyngeal type, 25% in pharyngolaryngeal type and 7% in laryngeal type. The cause of death was myocarditis in 5 case and pneumonia in 1 case. The mortality rate of myocarditis was 42% ( 5/12).
