Distal radial fractures are recognized as very complex injuries with a variable prognosis that depends upon the fracture type and the treatment method. The purpose of this study is to compare radiological and clinical result between external fixation and external fixation with primary bone graft in intraarticular comminuted fracture of distal radius. From January 1993 to December 1995, 32 patients with comminuted intraarticular fractures of the distal radius were treated using a external fixation. 15 cases were treated with ligamentotaxis without bone graft and 17 cases were treated with additional primary bone graft. In last follow-up examination, the mean loss of radial length, radial inclination and volar tilt were less in with bone graft group than without bone graft group. According to Demerit point system Excellent to good results were obtained in 88.2% in cases of external fixation and bone graft group, 66.6% in cases of only extemal fixation group. External fixation combined with primary bone graft is more useful method for the reconstruction and treatment of comminuted intraarticular fractures of the distal radius than closed reduction and external fixation because cancellous bone graft not only provides early mechanical stability but also helps to reduce and supports the depressed intraarticular fragments. Furthermore, this method not only prevents late collapse of fracture but also enhance fracture healing.

The most commonly used graft source for anterior cruciate ligament reconstruction is the autogenous bone- patellar tendon-bone graft unit. Despite a good success record, intraoperative technical errors and postoperative complications have been known. Author analyzed intraoperative technical errors and postoperative complications, in 44 patients who were treated at the department of orthopaedic surgery, chosun university hospital from Jan. 1994 to Jun. 1996. The most common intraoperative technical errors was screw graft divergency in 5 cases. Other intraoperative technical errors were too anteriorly location of femoral tunnel in 1 case, too anteriorly location of tibial k femora) tunne.l both in 1 case, graft tunnel mismatching in 1 case, graft pullout in 1 case and partial destruction of posterior cortex of femoral tunnel in 1 case, fracture of the bone plug in 1 case. The most common postoperative complication was patellar tendinitis in 20 cases (45.5%). Other postoperative complications were anterior knee pain in 14 case. (31.8%), patellar crepitation in 12 cases (27.3%), quadriceps atrophy in 9 cases (20.5%), arthrofibrosis in 3 cases and graft failure in 2 cases. Author concluded the causes of intraoperative complications were technical errors, and anteriorly location of graft tunnel is most influenced factor to final fuctional results. To eliminate the postoperative complications, intraoperative technical errors should be avoided and also accelerated rehabilitation should be done.

Nevus sebaceus of Jadassohn is a hamartoma of the skin with the potential to develop benign and malignant neoplasms. This case was characterixed by multiple basal cell epitheliomas, clinically one reddish nodule and multiple pigmented papules, arising in the nevus sebaceus. Histologically, epithelial papillomatous hyperplasia and high-positioned hyperplastic sebaceous glands were found, and tumor nests consisting of basaloid cells with peripheral palisading arrangements were mainly situated in the upper dermis without significant infiltrative growth. We report a rare case of nevus sebaceus with multiple basal cell epitheliomas in the right cheek of a 49-year-old woman.

PURPOSE: To determine the usefulness of MR urography technique for the evaluation of urinary systems in patients with obstructed urinary tract and normal volunteers with non-obstructed urinary tract after intravenous normal saline and diuretic injection. MATERIALS AND METHODS: Three normal volunteers and 12 patients with urinary tract obstruction [ureteral calculi(n=8), extraurinary mass(n=1), ureteral tumor invasion(n=3)] underwent MR urography using a 1.0T scanner and a 2D non-breath-hold heavily T2-weighted fast spin-echo sequence. These acquisition were postprocessed with a maximum intensity projection (MIP) algorithm. Two acquisitions were performed, the first prior to saline solution infusion following standard MR urography procedures, and the second, within 2-3 minutes of the infusion of 250 ml saline solution followed by 20 mg of Lasix administered intravenously. For this latter, drug-induced MR urography procedures were followed. RESULTS: In healthy volunteers (n=3) and those experiencing partial obstruction (n=4) by a urinary stone, drug-induced MR urography provided better images of the urinary tract than did standard MR urography. In those in whom a urinary stone or tumor had caused complete obstruction (n=8), standard MR urography provided good images, as did drug-induced MR urography. CONCLUSION: In patients with a partially or non-obstructed urinary tract, drug-induced MR urography provided better anatomic and functional details of the kidney and urinary tract than did standard MR urography. In those experiencing complete obstruction of the urinary tract, however, standard or drug-induced MR urography permitted very adequate evaluation of the tract, and drug-induced MR urography was unnecessary.

Strongylodiasis is universal in distribution but is most abundant in countries with a tropical climate. Although infestation by Strongyloides stercoralis is usually limited to the intestines, dessemination of this helminth in debilitated host can be lead to death with various clinical disorders. characterized by profound malabsorption, diarrhea, electrolyte imbalance, gram negative or opportunistic fungal sepsis, coma and death. Cell-mediated immunity contributing significantly to the control of helminthic infections, may be suppressed by carcinoma, immunosuppressive chemotherapy and use of corticosteroids. Diagnosis of Strongyloidiasis is achieved by an examination of samples of feces, duodenal aspirates and sputum of patients for Strongyloides stercoralis. Treatment of strongyloidiasis is twofold : correction of the immunosuppressive state by withdrawal of immunosuppressive drug, if possible, and vigorous treatment with thiabendazole. Testing for strongyloidiasis is especially recommanded before treating a patients should be monitored for infection by Strongyloides stercoralis and other opportunistic infection. We are reporting a case patient with Strongyloides stercoralis hyperinfection and pulmonary tuberculosis who had been. used corticosteroid for persisting polyarthritis.

We herein describe a case of a 55-year-old healthy woman with localized primary thymic amyloidosis presented as a mediastinal mass, found incidentally by chest radiography. Computed tomography revealed a 4.1 cm soft tissue lesion with nodular calcification in the left anterior mediastinum. The resected specimen was a well-defined lobulating mass with calcification. Microscopically, the mass was consisted of amorphous eosinophilc hyalinized substances involving the thymus and intrathymic lymph nodes. These eosinophilic substances showed apple-green bi-refringence under polarized light after staining with Congo red. In immunohistochemical study, they were positive for kappa and lambda light chains and negative for amyloid A. There was no evidence of systemic amyloidosis in clinical investigations. A final diagnosis of localized primary thymic amyloidosis was made.

BACKGROUND: Dimethyl sulfoxide (DMSO) is a strong urticariogenic agent and a primary irritant. A DMSO test which measures erythema and wheal responses in skin after exposure for 5 min could be a simple and easy method in evaluating cutaneous irritation. Several non-invasive bioengineering methods for the evaluation of skin irritancy have been developed in recent decades. OBJECTIVE: To evaluate whether the DMSO test using filter paper discs instead of the open well with measurements of transepidermal water loss (TEWL) and erythema index (E-index) could be useful to study skin irritancy. METHODS: Twenty healthy volunteers (19-29 years, 10 males and 10 females) with no history of atopic dermatitis were included. DMSO solutions (90%, 95%, and 100%) of 60l were applied to the left volar forearm for 5 min using filter paper discs (12mm) for large Finn chamber. Visual scores (whealing scores and erythema), TEWL and E-index were measured at 30 min after removal of the filter papers. RESULTS: The number of subjects showing erythema and wheals after DMSO exposure were: 6 (30%), 8 (40%) with 90% DMSO solution; 14 (70%), 15 (75%) with 95% DMSO solution; and 20 (100%), 20 (100%) with 100% DMSO solution, respectively. Whealing scores were 0.5±0.6 (90%), 1.4±1.1 (95%), 3.5±0.9 (100%), and erythema ones were 2.9±4.9 (90%), 7.7±7.2 (95%), 20.0±6.5 (100%). E-index results were 10.0±3.4 (90%), 10.9±3.1 (95%), 12.3±2.7 (100%), and TEWL values were 14.6±4.9 (90%), 21.0±8.8 (95%), 44.9±15.3 (100%). As the DMSO concentrations were increased, there were significant increases in whealing scores, and erythema and TEWL values. E-index results were not significant, but showed a rising score tendency. There were no significant differences between the males and the females. CONCLUSION: DMSO testing may be a quick and simple method to assess cutaneous irritation. Also, TEWL measurements may be more accurate and sensitive than those of E-index measurement in the assessment of erythema and wheals. DMSO testing using filter paper discs with TEWL measurement could be a useful method in the study of cutaneous irritation.
