A case of Lymphangiomatosis of the skeleton and soft tissue in a 23 years old woman is presented. Lymphangiomatosis are benign tumors formed of lymphatic vessel and like hemangiomatosis are probably best thought of as harmatomatous malformation. As term imply, the endothelial space in these lesions are lymph-rather than blood containing. Bone involvement are very rare condition that affect mainly the ilium and features a largely lytic pattern, consisting of tiny elliptical radiolucents slots. Treatment and Prognosis depend on the site and extent of involvement and progression. Although irradiation may be the treatment of choice, the lesions have not been usually successfully treated.

We reviewed 174 total hip arthroplasty (25 were revision procedure) and 65 bipolar hemiarthroplasty procedure followed by more than 6 months at Chungnam National University Hospital from July, 1992 to March, 1995. These were performed on 189 male and 50 female patients. We have followed up average 45.8 months and obtained following results; The dislocation rate is 3.76% (9 of 239 cases) and the dislocation rate of revision arthroplasties (16%: 4 of 25 cases) is higher than those of primary hip arthroplasties (2.6%: 5 of 214 cases). Among Nine dislocations, 8 cases (89%) were between fifth and seventh decade and all cases are men. All dislocations occured within 5 weeks postoperatively. Because 6 of 9 cases were due to poor compliance, the patient's cooperation during postoperative recovery is essential to prevent postoperative dislocation. The capsulectomy, surgical approach, or immobilization of patients after operation are unrelated to dislocaton. For the prosthetic factors, 7 cases dislocated posteriorly is appeared that the plane of the cup was between 3 and 9 degrees of anteversion, and also less than the normal range. Stable outcome without surgical operation was achieved in 7 of 9 dislocation. Among 2 patients who had recurrent dislocation after optimum conservative treatment, one had infected arthroplasty and the other had a impinged anterior thick capsule formation around the head. We concluded that the predisposing factors for dislocation after hip arthroplasty is multifactorial.

We performed a retrospective analysis of twenty-four consecutive hip arthroplasties (Total Hip Arthroplasty 18, Bipolar Arthroplasty 1, Cup revision 5) during which intraoperative frozen sections were analyzed to identify the occult active infection. We also reviewed the data such as laboratory findings (ESR, CRP), intraoperative culture, hip joint sonographic evaluation and permanent histologic section. Among the twenty-four patients those who received hip arthroplasties, 10 cases received revisional hip arthroplasties due to painful hip prosthesis loosening, 9 cases with infected hip prosthesis, 3 cases with infection after open reduction and internal fixation due to hip fracture and 2 cases with septic hip sequelae. Intraoperative frozen section had been obtained during staged revisional hip arthroplasties to determine the presence of active infection. We considered positive for infection if it shows more than 10 PML/HPF (Polymorphonuclear leukocyte /high power field) in at least 5 distinct microscopic fields from intraoperative tissue frozen section and postponed implantation of prosthesis. If it shows less than 5 PML/HPF, we performed revisional hip prosthesis implantation. We decided the implantation based on patient's condition, laboratory findings and intraoperative tissue conditions if it shows between 5 and 10 PML/HPF from intraoperative frozen section. At last follow up, 20 of 21 patients who had a revisional hip arthroplasties as below 10 PML/HPF from intraoperative frozen section remained free of infection (Specificity; 95%). We concluded that analysis of the intraoperative frozen sections is a reliable predictor as a guide to sepsis for the successful hip joint arthroplasties.

BACKGROUND AND OBJECTIVES: An experimental model of bacterial rhinosinusitis is essential to study the pathogenesis of rhinosinusitis. To our knowledge, there hasn't been an experimental model using rats for bacterial rhinosinusitis, where Staphylococcus aureus is directly inoculated to the rat nose. Staphylococcus aureus is also a predominantly isolated bacterial pathogen in the episode of acute rhinosinusitis. The aim of this study was to develop a rat model of rhinosinusitis induced by Staphylococcus aureus, ATCC 25923. SUBJECTS AND METHOD: The infected Sprague-Dawley rats (4-6 week-old male) were applied intranasally with 40 microliter of Staphylococcus aureus, ATCC 25923, which corresponds to 108 colony-forming units per milliliter, which in turn corresponds to a No. 1 McFarland turbidity by spectrophotometer (VITEK, USA). After the 2nd, 5th, and 14th day, the rats were killed respectively. RESULTS: Nasal sinuses were then observed at low power field (x40) for changes in the amount of inflammatory cell clusters in the sinus cavity. There were significant differences in the number of inflammatory cell clusters between the infected and control rats (p<0.05). The infected rats killed at the 5th day had significantly more inflammatory cell clusters within the sinus cavities (p<0.05). CONCLUSION: Staphylococcus aureus induces acute bacterial rhinosinusitis in rats as measured by increased inflammatory cell clusters. This study demonstrates the efficacy of a rat model of acute bacterial rhinosinusitis.

Pneumatosis cystoides intestinalis (PCI) is a rare condition characterized by multiple gas filled cysts in the intestinal wall. The diagnosis of PCI is usually made by colonoscopy, histology, or radiologic findings. We report a case of PCI in a 35-year-old man. The patient initially complained of watery diarrhea and abdominal bloating for 2 weeks. Simple abdominal X-ray demonstrated numerous, small, round, air densities on the right upper abdomen along the ascending and proximal transverse colon. Colonoscopy revealed numerous, 5-20 mm sized, sessile polypoid, balloon-like distended, protruding subepithelial masses covered with normal colonic mucosa from cecum to proximal transverse colon. We performed a CT colonoscopy and confirmed PCI with multiple air-filled cystic masses along the colonic wall from cecum to proximal transverse colon. The patient was treated with antibiotics and oxygen inhalation for 2 weeks. Follow-up CT colonoscopy revealed marked regression in the number and size of the air-filled cystic masses. Herein, we report the first case of the PCI in Korea diagnosed by CT colonoscopy. Follow-up evaluation with CT colonoscopy was performed after the treatment of the PCI. CT colonoscopy is a useful non-invasive diagnostic tool for the diagnosis of pneumatosis cystoides intestinalis.
