It has been reported in autopsy that most of the patients with Korean hemorrhagic fever had necrotic areas inthe anterior lobe of the pituitary gland. The high resolution CT of sella was performed to demonstrate thepossible pituitary necrosis in consecutive 13 patients with Korean hemorrhagic fever. Only 3 patients demonstrate normal sellar findings. Ten (77%) out of 13 cases reveal abnormal findings; 2 patients show typical empty sellar and the rest (8 patients) reveal localized low denstiy area in the anterior portion of the sella turcica, which may be from partial empty sella, pituitary infarction or other unknown pathology. The low denisties within the sella will be discussed.

Four patients were treated who had limited flexion of the hips and various degrees of contracture of the abduction and external rotator muscles because of fibrosis of the gluteus maximus muscle. Each patient had a typical restriction of motion such that an affected hip could not be flexed in the usual sagittal plane, but had to be flexed in abduction. Genetic, congenital and postnatal factors have been suggested as the cause of fibrosis of gluteus maximus muscle. Three of the 4 patients reported here are of congenital origin and another one is of postnatal factor repeated intramuscular injections. Excellent correction of the hip contracture was achieved in all patients by division of the fibrotic bands.

OBJECTIVES: It is suggested that frequency of low turnover bone disease is much higher in diabetic renal osteodystrophy. We tried to find out whether bone scan images show less 99mTc-MDP uptake in diabetic renal ostwdystrophy. METHODS: We compared bone scan images of renal failure patients with and without diabetes. The number of patients studied was 134 (43 patients had diabetes and 91 patients did not). Two experienced nuclear physicians read Tc-99m-MDP bone scan twice separately and gave the score either 1 or 0 on 6 areas; axial skeleton, long bone, skull and mandible, periarticular areas, costochondral junction and sternum. The means of summed scores were compared using Students t-test. To exclude the effects of sex, age and serum creatinine concentration, we analysed these factors together with the effect of diabetes using analysis of covariance. We also interpreted on bone scan images, as classical renal osteodystrophy, renal failure and normal. RESULTS: The intra- and interobserver variations were very low. Patients of diabetes group showed significantly lower mean of summed score(2.0+/-0.95) compared to patients of non-DM group(3.3+/-1.2). Analysis of covariance revealed that lower score of diabetes group was independent of sex, age and serum creatinine level. of diabetes group, 2 nuclear physicians interpreted bone scans as classical renal osteodystrophy in 60% and 56%, However, they interpreted bone scans of non-DM group in 80%, 88%(between-observer k: 0.74). Chi-square test showed that this difference was statistically significant (p<0.05). CONCLUSION: Bone scan image of diabetic renal osteodystrophy showed less 99mTc-MDP uptake, which meant low osteoblastic activity. This influence of diabetes upon bone uptake was significant after considering other confounding factors.

OBJECTIVE: The purpose of our study is to find out the therapeutic effectiveness, reproductive outcome, and the diagnostic pathologic findings of the patients treated with resectoscopy. METHODS: We examined 110 patients who complained infertility, abnormal uterine bleeding and menorrhagia from May. 1995 to Dec. 2000 via office. Among the infertility and abnormal uterine bleeding patients with abnormal endometrial lesion, resectoscopy was performed and then the resected tissues was sended for pathologic examination, except IUA, uterine septum, and double uterus. After resectoscopy, we inserted Lippes loop and medicated premarin 2.5 mg, 54 days and medroxyprogesterone acetate 10 mg, 10 days to the IUA patients. In AUB patients, we only injected methergin for bleeding control. They visited office after 1 month, and the follow up for endometrial state was done through TVS, HSG, or hysteroscopy. RESULTS: Among the 44 infertility, 41 (93%) had normal endometrium findings. Of twenty pregnancy (48.8%), seven (35%) ended in a second trimester abortion, thirteen (65%) in a full-term infant. Among the 66 with abnormal uterine bleeding, the 62 (93%) had normal endometrial finding and normal menstruation pattern. But 2 patients recurred their symptom, then hysterectomy was done 3, 5 years later respectively. Most of the patients who performed histopathologic study were diagnosed as leiomyoma (59.4%), and then endometrial or endocervical polyp (25.3%) and residual placenta tissue (3.8%) respectively. CONCLUSION: The 101 patients (91.8%) improved their symptoms and intrauterine lesion. we suggest this technique which of diagnostic accuracy, cost safety, convenience, operation time, and patient's satisfaction.

Purpose: To analyze the clinical results of cementless total hip arthroplasty (THA) for the treatment for osteonecrosis of the femoral head in renal transplant recipients. Materials and Methods: Twenty-one cementless THA were performed in 15 renal transplant recipients with advanced osteonecrosis of the hip. The average interval from the transplant to arthroplasty was 43 months (range, 7-122 months). The mean age at the time of arthroplasty was 35 years (range, 25-58 years). The average preoperative Harris hip score was 40 points (range, 31-57 points). The mean follow-up period was 45 months (range, 24-101 months).The articulations were metal-on-polyethylene bearing in 1 case, metal-on-metal in 6 cases, and ceramic-on ceramic in 14 cases. Results: The average postoperative Harris hip score was 91 points (range, 82-94 points), and there were no problems such as wound healing or infections despite the immunosuppressed state. Radiographically, there was one case of femoral and acetabular osteolysis, which had used metal on polyethylene articulation, 80 months after surgery. There was neither aseptic loosening nor dislocation after an average 45 months. Heterotopic ossification was detected in 1 case. Conclusion: The early results of a cementless THA in this young group of renal transplant recipients is encouraging.

Schwannomas are benign tumors derived from the Schwann cells of the nerve sheath. These are rare tumors that can be found in any part of the body although fewer than 4% of these tumors involve the nasal cavity and paranasal sinuses. Here, we present three cases of sinonasal schwannoma. The tumor masses were removed by endoscopic excision under general anesthesia. Pathological examination of the excised specimens confirmed schwannoma and the tumor cells were immunoreactive for S-100 protein. The patients are doing well with no evidence of recurrence.

PURPOSE: To compare the effect of humidified high flow nasal cannula (HHFNC) with that of nasal continuous positive airway pressure (NCPAP) as the mode of extubation in very low birth weight infants (VLBWI). METHODS: Medical records were retrospectively reviewed for 219 VLBWI who were admitted to the neonatal intensive care unit of Ajou University Hospital from January 2009 through December 2012; 87 were supported by noninvasive ventilation (NIV) after extubation (HHFNC n=47, NCPAP n=40). Extubation failure was defined as the need for reintubation within 1 week of extubation. RESULTS: (1) There were no significant differences between the groups in demographic data such as gestational age, birth weight, and age at extubation. (2) There were no significant differences in fraction of inspired oxygen (FiO2) (HHFNC 0.23+/-0.03 vs. NCPAP 0.23+/-0.03, P-value .937) and peak inspiratory pressure (HHFNC 11+/-6.6 cmH2O vs. NCPAP 10.3+/-3.4 cmH2O, P-value .559) before extubation. (3) The rate of extubation failure and FiO2 values after extubation were similar in the 2 groups (extubation failure, HHFNC 5/47 vs. NCPAP 5/40, P-value 1.000; FiO2, HHFNC 0.24+/-0.05 vs. NCPAP 0.25+/-0.04, P-value .399). (4) Among patients who received NIV after extubation once but did not receive further intubation, the duration of NIV or duration of oxygen supply were not significantly different between the groups (NIV, HHFNC 12.4+/-9.1 days vs. NCPAP 8.7+/-12.3 days, P-value .159, oxygen supply, HHFNC 49.0+/-40.3 days vs. NCPAP 50.9+/-41.3 days, P-value .844) or bronchopulmonary dysplasia rate (HHFNC 24.3% vs. NCPAP 34.4%, P-value .430). CONCLUSION: HHFNC is as effective as NCPAP for weaning VLBWIs from invasive mechanical ventilation.

BACKGROUND AND OBJECTIVE: Abciximab has been shown to have beneficial effects beyond the improvement in the patency of an infarct-related artery and the microvascular integrity. However, it remains uncertain whether abciximab may lead to beneficial effects on the left ventricular remodeling in patients with an acute myocardial infarction, treated with primary percutaneous coronary intervention (PCI). Therefore, whether abciximab is effective in the left ventricular remodeling in patients with acute myocardial infarction, treated with primary PCI, was investigated. SUBJECTS AND METHODS: The study included 28 patients with an acute myocardial infarction (1 vessel disease) that had received either a primary PCI alone (group A, n=14) or an abciximab+primary PCI (group B, n=14). The baseline characteristics of the two groups were similar, with the exception of a thrombusburden lesion. All patients were examined by echocardiography within 72 hours, and at an average 11.7 months after the acute myocardial infarction. The change in the left ventricular end-diastolic volume index, end-systolic volume index and ejection fraction, between the two groups, were compared. RESULTS: At an average follow-up of 11.7 months, the left ventricular volume indices were smaller, and the left ventricular ejection fraction higher, compared with those at the baseline in each group. The change of the left ventricular end-diastolic volume index (-7+/-3 mL/m2 vs. -9+/-2 mL/m2, p=0.56), the left ventricular end-systolic volume index (-8+/-3 mL/m2 vs. -9+/-2 mL/m2, p=0.73) and the left ventricular ejection fraction (7+/-3% vs. 9+/-2%, p=0.49) did not show significant differences between groups A and B. CONCLUSION: These results suggest that abciximab does not improve the left ventricular remodeling in patient with an acute myocardial infarction, treated with primary PCI.
