PURPOSE: We performed this study to evaluate the changes of gallbladder ejection fraction (GBEF) in diabetic patients with or without autonomic neuropathy. MATERIALS AND METHODS: This study included 37 diabetic patients (25 women, 12 men, mean age 51 years) and 24 normal controls (10 women, 14 men, mean age 38 years). After intravenous injection of 185 MBq of 99mTc-DISIDA, serial anterior abdominal images were acquired before and after fatty meal. Regions of interest were applied on gallbladder and right hepatic lobe on 60 and 90 minute images to calculate GBEF. RESULTS: GBEF was significantly reduced in diabetes with autonomic neuropathy (43+/-12.3%) and without autonomic neuropathy (57.5+/-13.2%) compared with normal controls (68+/-11.6%, p <0.05). And also, GBEF was significantly reduced in diabetes with autonomic neuropathy compared with diabetes without autonomic neuropathy (p <0.05). Fasting blood glucose level, age, sex, hemoglobin A1c, body mass index, serum lipid level were not different in these two diabetic patient groups (p>0.05). When 50.2% of GBEF was used as the criteria for diabetic autonomic neuropathy, the sensitivity and specificity were 80%, 76.5%, respectively. The area under receiver operating characteristic curve was 0.846. CONCLUSION: GBEF of diabetic patients with autonomic neuropathy was significantly reduced than that of diabetic patients without autonomic neuropathy.

Psoriasis has been known to have various humoral and cellular immune abnormalities. And adenosine deaminase (ADA) activities are known to be decreased in immune deficiency diseases. The present study was designed to measure the activities of ADA in sera and erythrocytes of psoriasis patients by Giustiss method. There were no significant differences in the erythrocytes ADA activities between normal subjects (9, Gp+4 43 units/10 cells) and psoriasis patients (7, 29+3. 64 units /10 cells). The ADA activities in sera of the psoriasis patients (13. 15+3. 43 units/ L) showed lowered activities than those of normal subjects (20. 44-2, 07 units/L).

Congenital scoliosis is defined as a lateral curvature of the spine caused by congenital anomalies of the vertebral development. In this study seventeen congenital scoliosis patients seen and treated by either Milwaukee brace or surgical intervention at Department of Orthopedic Surgery, Seoul National University Hospital from December 1972 to April 1978 were evaluated according to frequency of the curve pattern, character of the deformity, method of treatment and its correctability. The following results were obtained in this study. 1. Age distribution was from 2 to 39 years and mean age was 13.4 years. 2. The most common deformity pattern was hemivertebra in 8 cases (47.1%), unilateral unsegmented bar in 4 (23.6%) and mixed type in 3 (17.6%). 3. The most common curve level was thoracic in 6 cases (35.3%), followed by thoracolumbar in 4 (23.5%) and lumbar in 4 (23.5%). 4. The best corrected type by Milwaukee brace was trapezoid vertebra (29.4%) and then mixed type(26.1%), followed by block type (20%) and hemivertebra(2.3%). 5. The operative treatment was performed in the cases of unilateral bar and progressive type with Milwaukee brace. In terms of the correctability of the curvature, the surgical intervention was better than the conservative treatment, with the result of its average correction of 33.5% that is compared with 15.9% of Milwaukee brace. 6. Halofemoral traction was effectively applied in the cases of rigid and severe curve; the initial curve 76.3 degress with 21.3% of flexibility. 7. Loss of correction in operative treatment was 2.3 degrees (6.5%).

Tuberculous spondylitis is not rare disease. Today the posterior instrumentation and posterior or posterolateral fusion concomitant with the anterior decompression and anterior interbody fusion have been used for the treatment of spinal tuberculosis. The authors experienced a case of tuberculous spondylitis complicated with descending aortic pseudoaneurysm. An aneurysm is defined as a localized dilatation of an artery that is at least one-half the size greater than is expected for that artery. Pseudoaneurysm occurring after previous operation, trauma, and infection. Erosion of the thoracic aorta with the development of an fistula in the presence of infection is an unusual and difficult problem to manage. We report a case and review related articles briefly.

Although the management of fractures of the calcaneus still remains controversial, open reduction and internal fixation is gaining in popularity as the method of choice for the treatment of displaced intraarticular calcaneal fractures. However, open methods can make several complications such as neurovascular injury and infection. Thus we have performed the new technique of arthroscopic reduction and minimal internal fixation for displaced intraarticular calcaneal fractures in 5 cases. The results were evaluated between 12 and 16 months after surgery. A Bohler angle was restored to 25degrees-40degrees in all cases. Anatomical reduction of articular surface were obtained from 4 cases out of 5. No complications were found except 1 peroneal tendinitis. The clinical results by Creighton-Nebraska health foundation assessment for fractures of the calcaneus were 3 excellent, 1 good and 1 fair. Even though this was a few case and a short term follow-up study, the arthroscopic assisted management of displaced intraarticular calcaneal fracture induced a little complications and satisfactory results.

PURPOSE: This study intended to examine the effect of pamidronate, when it was administrated in early estrogen deficiency period, by examining biomechanically bone mass generated in trunkal and extremity bone with bone strength examination. MATERIALS AND METHODS: 17-weeks-old 95 mice of Sprague-Dawley lines were divided into 1st group 28mice, 2nd group 25mice and 3rd group 42mice. The 1st group was sham-operated group, 2nd group underwent bilateral ovariectomy and then injected intravenously normal saline 0.05cc, and 3rd group underwent bilateral ovariectomy and then injected intravenously pamidronate 0.1mg/Kg. RESULTS: The strength of femur, tibia and spine was surveyed with Young' modulus. Femur and spine had a statistically significant difference between 1 and 2 group, 2 and 3 group, and tibia had between 2 and 3 group. CONCLUSION: In early osteoporosis, pamidronate administration is supposed to prevent or decrease osteoporosis and fracture resulting from osteoporosis.

BACKGROUND AND OBJECTIVES: Chronic sinusitis is a common disease in otolaryngology, but its pathologic mechanism has not been clearly known. Also, the evaluation method for the severity of chronic sinusitis is not established. The aim of this study was to analyze possible factors associated with the correlation between the radiological and pathological severity of chronic sinusitis. In addition, we assessed the profiles of inflammatory cells in the sinus mucosa and peripheral blood eosinophils in relation to the overall pathologic grades and OMU CT findings. SUBJECTS AND METHOD: Fifty specimens of pathologic sinus mucosa, obtained during endoscopic sinus surgery were stained with hematoxylin and eosin. Total inflammatory cells, plasma cells, neutrophils, lymphocytes and eosinophils were quantified. The preoperative OMU CT scans were scored by the staging system of Lund-Mackay. Also, the preoperative percentage of eosinophils in peripheral white blood cells were obtained with the complete blood count with differentiation. RESULTS: The count of total inflammatory cells, lymphocytes and eosinophils infiltrated in the diseased sinus mucosa correlated significantly with the severity of the pathologic grades and OMU CT scores. In addition, the CT scores assessed by Lund-Mackay system correlated significantly with the severity of the pathologic grades. CONCLUSION: The important indicators of the severity of the chronic inflammation in chronic sinusitis were OMU CT scores, overall pathologic grades, and total inflammatory cells, lymphocytes and eosinophils infiltrated in sinus mucosa.
