We measured the bone ingrowth rate on 22 retrieved human cementless porous coated acetabular cups by the help of computer graphics. All the acetabular cups had functioned well, and had had evidence of radiologic bony ingrowth before revising the acetabular cup. The reason for retrieval of the acetabular cups were: one with habitual dislocation, who with stem loosening, and 19 with polyethylene cup wearing. The period from initial surgery to retrieval surgery was 28 months to 108 months(average 56.1 months). All the retrieved porous coated acetabular cups showed macroscophic bony ingrowth, and the ratio of the whole porous surface to bony ingrowth area was showed 1.14% to 92.27% (average 36%).

A study was made of the respiratory effects of acute carbon monoxide poisoning in mongrel dogs. In this study the dogs were divided into two groups, namely the control and the experimental. In the experimental group, carbon monoxide poisoning was induced by the rebreathing of about 2% carbon monoxide gas mixture for 15 minutes, and the respiratory functions in this group were compared to those in the control group. A significant increase in the minute ventilation was noted in both the control and the experimental groups, and in the latter there was an increase in the respiratory rate and a decrease in the tidal volume compared to those in the control group. In both groups, oxygen consumption showed no significant change and there was a fall in the arterial carbon dioxide tension, but the carbon dioxide elimination was slightly lower in the experimental group.

PURPOSE: This study aimed to determine whether deep vein thrombosis (DVT) predominantly occurred on a particular side in the pelvic and lower extremity veins. MATERIALS AND METHODS: Among 259 consecutive patients with leg swelling, 65 were confirmed to have DVT in the pelvis and lower extremities, and enrolled in this study. The serum levels of initial D-dimer, antithrombin III, tissue plasminogen activator, factor VIII, proteins C and S, anticardiolipin antibodies immunoglobulin (Ig) G and IgM and lupus anticoagulant were measured and analyzed retrospectively. Lower extremity venous system was divided into 11 anatomic segments on each side, and thrombotic involvement in each segment was recorded to determine the laterality of thrombotic involvement for each patient. The presence of thrombus in a specific vein was assigned using a Thrombus Scoring System (TSS) score of 1. Predominant direction was determined based on the TpSS score for each side. RESULTS: Left-side predominat DVT (57%) was most frequent. Patients with both-side equivalent DVT had the highest total TSS score (P=0.022). The predominant side was significantly different between men (right 44.1%) and women (left 74.2%) (P=0.022). Patients with both-side equivalent DVT had the highest mean age (69.3+/-9.9 years) as well as the highest mean levels of initial D-dimer (13.8+/-20.7 microg/mL) and anticardiolipin antibody IgM (13.4+/-22.8 MPL) indicating increased coagulability. CONCLUSION: In the current study, left-side predominant DVT is most frequent in pelvis and lower extremities, and this phenomenon is more apparent in women. And both-side equivalent DVT is associated with the most advanced age and hypercoagulability.

Percutaneous method of Al pulley release for the trigger fingers using hypodermic needle or small sharp scalpel has been described by some authors. In our experience, however, these methods had some difficulties in handling the instruments and not easy to utilize proper technique. Therefore we designed a special scalpel for easy and safe percutaneous release of the Al pulley. The scalpel has a hook shaped end with a blade on the inner side. Insertion site through the skin should be 0.5cm distal to the Al pulley, and the hooked end is located at the proximal margin of the Al pulley followed by longitudinal cut of the pulley distally. We performed this procedure in 44 trigger fingers of 41 patients in our out-patient clinic. There were 9 males and 32 females with a mean age of 54.4 years (range, 24 to 83 years). Affected digits were 23 thumbs, 1 index, 13 middle, 5 ring and 2 little fingers. 9 of them were locked in flexion or extension. The duration of symptom was an average of 7.9 months. After a mean follow up of 11.3 months, 42 fingers (95.4%) were completely free of symptoms including triggering. One had mild residual triggering due to incomplete release of the pulley and another had re-release of the pulley for remaining flexion limitation. One finger showed mild bowstringing after release, which subsided in 3 months. One patient complained of persistent pain and tenderness over the release site. There were no injuries of nerves or vessels and no infections. The duration of discomfort after release ranged from 3 to 70 days (av. 18.5 days). All patients, except one, were satisfied with the treatment method and their results. We think that percutaneous release of trigger fingers using our special scalpel is a very effective and convenient procedure both to surgeons and patients. It can be easily and safely performed in out-patient clinic with successful results.

Pedunculated lipofibroma is a rare disorder characterized by ectopic deposits of mature adipose tissue in the dermis. It is a dorne shaped or sessile papule which occurs at any site and develops later in life. We, herein, report two cases of pedunculated lipofibroma which have developed on the chin of a 64-year-old man and the buttock of a 47-year-old woman.

We report a case of primary transitional cell carcinoma developed in bladder vdiverticulum with brief review of literatures. Patient was a 71 year-old man who had painless gross hematuria for 10 days. Excretory urogram showe a large diverticulum in the bladder. At cystoscopy a 0.5 x 0.5cm sized papillary mass was seen on diverticular mucosa. Urine cytology revealed class V transitional cell carcinoma. At pelvic CT, metastatic evidence was not seen. We carried out partial cystectomy involving diverticulum under the diagnosis of primary transitional cell carcinoma developed in vesical diverticulum. The histopathologic diagnosis was grade III, stage A transitional cell carcinoma combining with carcinoma in situ.

This study assessed the effect of vasodilator papaverine for the occlusive mesenteric ischemia in rats. Papaverine has been used for the treatment of nonocclusive mesenteric ischemia(NOMI), but its peripheral administration for the occlusive mesentric ischemia is known hazardous. This experiment was performed to confirm the detrimental effect of the peripheral administration of papaverine for the occlusive mesenteric ischemia in rats. The experimental animals were assigned to one of three groups. In the control group, laparotomy and thoracotomy were performed and blood samples were obtained from right atria of the rats. In one experimental group, after laparotomy and SMA ligation, papaverine was injected into the parietal peritoneum and the abdomens were closed. In the other experimental group, after laparotomy and SMA ligation, abdominal closures were performed. It is known that mesenteric infarction causes elevation of total serum creatine phosphokinase(CPK) and each of its three isoenzymes and it is also known that CPK BB isoenzyme is the earliest isoenzyme of the three. In this experiment, although there were no statistical significances, total CPK and all its three isoenzymes showed higher levels after 1hour in SMA ligation with papaverine treated group than those in SMA ligation alone group. And especially CPK BB isoenzyme revealed higher levels after 30 minutes in SMA ligation with papaverine treated group than that in SMA ligation alone. Therefore it is supposed that peritoneal injection of vasodilator papaverine might be hazardous for the occlusive mesenteric ischemia in rats.

This is a long term follow-up study to clarify whether arthroscopic synovectomy would be able to prevent further destruction of the articular cartilage in rheumatoid joints. Three hundred and eighteen rheumatoid joints of 94 patients who had surgery in the multiple joints(average 3.4 joints per person) and was followed for an average 39.9 months (range, 24-126 months) were selected. Diagnosis of rheumatoid arthritis was made according to the 1987 revised criteria of the American College of Rheumatology. The preoperative roentgenographic narrowing of cartilage space (modified classification of ARA) and the arthroscopic findings (grading of Outerbridge) were recorded. The points of investigation were 1) further destruction of articular cartilage on X-ray, postoperatively, and 2) reaccumulation of effusion. The results were as follows; 1) Knee Joint: Among 103 knee joints there were 92 (89.3%) Stage I, G-0 knees, 8 Stage II (G-2: 1, G-3: 3, G-4: 4 joints), and 3 Stage IIIB, G-4, preoperatively. The 3 Stage IIIB, G-4 knees showed progression of narrowing of joint space and were replaced by artificial joints two years after the synovectomy. 2) Wrist joint: Fifteen joints (28.3%) out of 53 joints were Stage II, G-4, and 2 joints joints (3.8%) were Stage I, G-3, preoperatively. They were progressed to Stage IIIB at final follow-up. 3) Other Joints: There was no further narrowing of the joint space following surgery in 22 fingers, 2 toes, 34 elbows, 34 shoulders and 70 ankles. 4) Prognosis seemed to depend upon postoperative medication. From these results it would be suggested that the rate and severity of recurrence of synovitis and further destruction of articular cartilage can be decreased with early synovectomy so long as proper anti-rheumatic medication is followed, although the surgery can not halt the disease process.
