Reactive perforating collagenosis, first described by Mehregan et al in ]967, is a skin disorder characterized by transepidermal eliniination of altered collagen fibers. This rare disease appears as recurrent, umbilicated, crusted papules in response to minor trauma. We report here a case of reactive perforating collagenosis in a 21-year-old man. Examination of the skin revealed a number of centrally umbilicated, asymptomatic papules filled with keratotic plugs in various development and regression. The lesions were distributed on the dorsa of the hands, face, and neck. The biopsy spccimen showed a few of thin bundles of collagen which v ere extruded from the dermis through the atrophic epidermis and the turinels within the epidermis, reaching the buttom of the plug.

Purpose: To evaluate and introduce the technique of C-arm guided aspiration and an injection of a mixture of corticosteroid and local anesthesia for the treatment of calcific tendinitis of the rectus femoris around the hip joint. Materials and Methods: Between March 2003 and May 2005, C-arm guided aspiration and an injection of a mixture of corticosteroid and local anesthesia were performed on 5 patients and a local excision were performed in 1 patient for the treatment of calcific tendinitis of the rectus femoris. The minimum follow-up period was 6 months. The radiology evaluation revealed the presence and size of the calcification. The clinical evaluation involved checking the level of pain relief, range of motion, recurrence, complications. Results: The hip pain improved immediately after treatment. There were no recurrences or complications. Conclusion: The combined treatment of C-arm guided aspiration and an injection of a mixture of corticosteroid and local anesthesia is an effective method for treating calcific tendinitis of the rectus femoris, which can induce rapid symptom relief without any surgical morbidity.

BACKGROUND: In patients with mitral stenosis, the degree of pulmonary hypertension is expected to be related to the severity of mitral valve obstruction. However, some patients with severe mitral stenosis do not develop reactive pulmonary hypertension. MATERIALS AND METHODS: We evaluated 34 patients with symptomatic mitral stenosis undergoing percutaneous mitral valvuloplasty by clinical, echocardiographic, and invasive hemodynamic(cardiac cathrterization) data. Prevalvuloplasty data were available in 34 subjects[mean age 38+/-9 year ; women 74% ; NYHA class 1 (6 patients), class 2 (17 patients), class 3 (7 patients), class 4 (4 patients) ; in electrocardiography, NSR(23 patients), Atrial fibrillation(11 patients)]. RESULTS: 1) The pulmonary vascular bed gradient was significantly correlated with pulmonary vascular resistance(r=0.91), mean pulmonary artery pressure(r=0.82), transmitral mean pressure gradient(r=0.64) and mitral valve area(r=-0.48). The pulmonary vascular resistance was significantly correlated with mena pulmonary artery pressure(r=0.77), transmiral mean pressure gradient(r=0.61) and mitral valve area(r=-0.54), NYHA functional classification(r=0.36). However, the pulmonary vascular bed gradient and pulmonary vascular resistance was not significantly correlated with age, sex, cardiac output, the severity of mitral regurgitation and mean left atrial pressure. 2) The mean pulmonary artery pressure was significantly correlated with mean left atrial pressure(r=0.80), transmitral mean pressure gradient(r=0.72) and mitral valve area(r=-0.47). 3) When patients were divided into those with a pulmonary vascular bed gradient > 12mmHg and Atrial Pressure ; Cardiac Output ; Echocardiography ; Electrocardiography ; Female ; Heart Diseases ; Humans ; Hypertension, Pulmonary* ; Mitral Valve ; Mitral Valve Insufficiency ; Mitral Valve Stenosis* ; Pulmonary Artery ; Vascular Resistance

We present a case of medial malleolus and deltoid ligament loss with extensive overlying soft tissue defect from crushing injury. The resultant gross medial ankle instability necessitated deltoid ligament reconstruction using a bone-patellar tendon graft.

The practice of adding antibiotics to anterior chamber-irrigating solutions as a prophylaxis for endophthalmitis has been used recently.To evaluate corneal endothelial toxicity of different concentrations of antibiotics in irrigating solutions, rabbit corneas were mounted in the in-vitro dual-cham-bered specular microscope and the endothelium was perfused with glu-tathione-bicarbonate Ringer solution (GBR)containing antibiotics such as ofloxacin, vancomycin or cephapirin.Mate corneas were perfused with GBR alone and used as control.Corneal thickness was measured every 15 minutes throughout the perfusion period and corneal swelling rates were calculated. Swelling rates of corneas perfused with 2 /ml or 5 /ml ofloxacin, 60 microgram/ml or1 0 /ml vancomycin, and 10 /ml or 20 /ml cephapirin was not significantly different from that of control (p>0.05).The corneas perfused with 20 /ml cephapirin deswelled probably due to high osmolarity of it.Perfusion with 10 /ml vancomycin plus 5 /ml ofloxacin did not show corneal swelling compared to control (p>0.05).This study demonstrates that the above concentra-tions of antibiotics in irrigating solutions do not affect endothelial function of the rabbit cornea.

PURPOSE: The purpose of this study is to assess the clinical utility of multiplanar reformation images of helical CT in the evaluation of pancreatic diseases. MATERIALS AND METHODS: Helical CT scans of the pancreas were obtained in 30 patients with pancreatic diseases. Helical CT was performed with 5mm collimation at 5mm/sec table speed during rapid injection of intravenous contrast agent using power injector. After scanning, helical volume data were reconstructed at 2mm interval and then multiplanar reformation of the pancreas and adjacent structures was done. In both prospective reconstructed axial images and multiplanar reformation images, detection of pancreatic lesion, extent of lesion, and vascular and bile ductal changes were analyzed with a grading system of 1,2, 3. RESULTS: The mean grade of detection of pancreatic lesions was 2.37 in the prospective axial image and 2.83 in multiplanar reformation image, extent of diseases was 2.40 in prospective axial image and 2.97 in multiplanar reformation image, and vascular and bile ductal changes was 2.00 in the prospective axial image and 2.97 in multiplanar reformation image. All the differences were statistically significant (P<0.0001). CONCLUSION: Multiplanar reformation images of helical CT are useful in the evaluation of pancreatic diseases and especially in the demonstratibn of complex anatomic relationships between the pancreas and surrounding structures.
