Nasopharyngeal angiofibroma is a relatively rare, but is a well known tumor that occurs almost in male, most frequently during the adolescent stage. Its character is histologically benign but clinically malignant because of locally invasive character to the adjascent structures, massive bleeding tendency during surgical procedure and high recurrence rate after treatment. Recently many advancements diagnostic method and surgical technique has reached satisfactory result in treating this difficult tumor. The authors present a case of nasopharyngeal angiofibroma in 16 years old male patient, who was received surgical removal of the tumor through the transpalatal approach after full diagnostic evaluation and preoperative hormonal therapy.

A case of pulmonary alveolar proteinosis is reported. Most of the alveolar spaces were filled with amorphous deep eosinohilic material which revealed strong positive reaction to periodic acid-Schiff staining. Electron microscopic observation of this material showed numerous lamellar bodies in the alveolar spaces and cytoplasms of alveolar macrophages. A part of them were concentric multilamellated type A lamellar bodies and the other were finger printlike type B bodies. Combined type A and type B lamellar bodies were rarely present. From the above features it is suggested that both type A and B lamellar bodies could be transformed one another and those lamellar bodies may be originated from pulmonary surfactant.

Behcets disease is a chronic systemic disease of unknown etiology, which is characterized by the recurrent orogenital ulcers, eye involvement and skin manifestations. In addition to the major symptoms, it includes arthritis, vasculitis, neurologic manifestations and gastrointestinal lesions. We report a case of Behcets disease associated with intestinal ulcers. The patient, a 45-year-old female, who had been treated under the diagnosis of Behcets disease for 4 years, presented with swallowing difficulty, vaginal discharge and persistent right lower abdominal pain. Colonoscopic examination showed multiple ulcers on the ileocecal region which is reported as the most common site of gastrointestinal Behcets disease. Gastrointestinal evaluation can be useful in diagnosis of Behcets disease, especially in a patient with gastrointestinal symptoms.

The purpose of this study was to evaluate the histologic difference that occured after trichloroacetic acid(TCA) chemical peel in an animal model that was pretreated with Tretinoin alone or Tretinoin-based combined pretreatment kit. Eight Hartley white guinea pigs were used in our study. The dorsal skin of the guinea pigs was divided into six equal squares(2x2 cm). Upper two areas of these six were not pretreated, middle two areas were pretreated for 4 weeks with Tretinoin alone and lower two areas were pretreated for 4 weeks with Tretinoin-based combined kit. Each guinea pig underwent chemical peel with 50% TCA. The wounded areas were biopsied at post-peeling 3 weeks and 6 weeks. The histology revealed that those animals pretreated with combined kit healed quicker than the animals pretreated with Tretinoin alone. This study implies that if patients are treated with Tretinoin-based-combined pretreatment kit before undergoing chemical peel, the pretreatment time will be shortened.

Subcutaneous fat necrosis of the newborn is an uncommon disorder characterized by firm b-cutaneous plaques and nodules usually appearing shortly after birth. It runs a relatively be, n course and may completely resolve in a few months without any recurrence. We report a case of subcutaneous fat necrosis in a 15 day-old male suffering from severe p inatal asphyxia and hypoxic cardiomyopathy, who presented with indurated subcutane s nodules and plaques on the both shoulders and the back. Histologically the subcutaneous fat showed focal necrosis with needle-shaped clefts, lymphohistiocytic infiltration and foreign body reactions consistent with subcutaneous fat necrosis of the newborn. In our patient, compromised cardiac output due to cardiomyopathy might have aggravated hypoxic condition and it could be speculated that cardiomyopathy-induced systemic hypoxia gave rise to hypothermia of the skin as a result of peripheral vasoconstriction. This report presents a causal relationship of cardiomyopathy and subcutaneous fat necrosis of the newborn.

BACKGROUND: Since percutaneous mitral valvuloplasty(PMV) using balloon was introduced by Inoue in 1984, this procedure has been accepted as a new non-surgical therapeutic modality for the treatment of selected patients with mitral stenosis. Pregnant women with mitral stenosis has suffered from life threatening complication due to altered hemodynamic changes and heart failure. Surgical valvotomy has been performed after failure of medical therapy with high risk of fetal mortality and teratogenicity. PMV can be an adequate alternative to surgical valvotomy in pregnant women. METHODS: After precise echocardiographic examination of mitral valve and its surrounding structures including thrombi in left artrium was performed, antegrade transseptal procedure was done in all 3 cases with abdominal shield using Inoue balloon technique. RESULTS: Mitral valve area increased over 1.5cm2 and hemodynamic variables improved immediately after PMV. Symptoms subsided soon after PMV in all 3 cases. Healthy normal babies were delivered transvaginally without difficulties in all 3 patients. CONCLUSIONS: Percutaneous mitral valvuloplasty is a safe and effective therapeuteic alternative to surgical valvotomy in a pregnant women with mitral stenosis who failed medical therapy, in a high risk or symptomatic pregnant women.

PURPOSE: Long-term follow-up results of concurrent bilateral or unilateral cementless hip arthroplasty were compared. MATERIALS AND METHODS: Forty eight and 49 patients with concurrent bilateral and unilateral hip artrhoplasties who had more than a 17-year follow-up time were selected. At final follow-up, mean ages were 69.1 and 66.7 years old in the bilateral and unilateral groups, respectively. Mean follow-up times were 21.5 and 22.4 years in the bilateral and unilateral groups, respectively. Clinical results were attained using Harris hip score and standardized anteroposterior and lateral view X-rays. RESULTS: The bilateral group had mean Harris scores of 44.3(standard deviation 3.78) preoperatively, and 81.2 (10.75) at final follow-up. For the unilateral group, the mean scores were 46.5(3.27) preoperatively, and 80.1 (12.05) at final follow-up. At final follow-up, an acetabular cup was securely located in 78.9% and 82.8% of the bilateral and unilateral groups, respectively, and all cases showed firm fixation of the femoral stem in both groups. Osteolysis around the cup and stem were found in 26.3% and 31.4% of the bilateral group and 16.6% and 17.1% of the unilateral group, respectively. Polyethylene wear rate was 0.17 mm/yr and 0.16 mm/yr in the unilateral and bilateral groups, respectively. Using the Kaplan-Meier method, 17-year survival rates for cup and stem were 78% and 89% in the bilateral group, respectively, and 78% and 86% in the unilateral group, respectively. CONCLUSION: In 17-year long-term follow-up, concurrent bilateral hip arthroplasty was insignificantly different clinically and radiologically from the result of unilateral hip arthroplasty.
