Pancreatic islet cell adenoma is a benign tumor of pancreatic beta-cell and a rare cause of hyperinsulinemic hypoglycemia in children. The authors experienced a case of pancreatic islet cell adenoma(Insulinoma)in a 11 year and 8 month old male who had frequent loss of consciousness and seizure. Enucleation was done after localization of tumor by selective celiac artery angiography and abdominal computed tomography. Diagnosis was confirmed by histologic findings as pancreatic-adenoma, gyriform growth pattern. A brief review of related literature was made.

The purpose of this study was to evaluate the prevalence rate of low back pain (LBP) in the high school students and to analyze the differences and correlations with the spinal-pelvic structural variations and disability index with LBP. The subjects are 499 high school students (236 males, 263 females: mean age, 16.38 years). They were assessed for LBP with the numerical rating scale (NRS) and for disability with the Korean version Oswestry disability index (KODI). All subjects were to take the plain radiographic examination for spinal-pelvic structural variations including thoracic, lumbar, thoracolumbar Cobb's angle, lumbar lordotic curve, sacral slope, pelvic tilt and pelvic incidence. All subjects were divided into two groups by NRS scores (0, 1=no/minimum pain group [NMP group], 2-10=low back pain group [LBP group]). The prevalence rate of LBP of all subjects was 56.7% (n=283). NRS and total KODI scores were higher in the LBP group (3.38 cm/11.83%) than NMP group (0.07 cm/2.74%) (p<0.001). In the spinal-pelvic structural variations analysis, the thoracic Cobb's angle was significantly high in LBP group (p<0.05), but others were shown no differences between the both groups (p>0.05). NRS had significantly positive correlation with KODI (p<0.001). NRS and KODI did not demonstrate any correlations with spinal-pelvic structural variations (p>0.05). In conclusion, this study showed high prevalence rate of LBP in the high school students, but did not show significant correlations with the spinal-pelvic structural variations and disability index.

A 21-year-old woman presented with bilateral optic neuritis, combined with central retinal vein occlusion. General physical examination and neurologic consultation revealed no other findings. Laboratory investigation yielded an elevated erythrocyte sedimentation rate, positive LE preparation, elevated ANA titer, and elevated blood urea nitrogen and creatinine levels. Diagnosis of systemic lupus erythematosus (SLE) was made. Renal failure developed quickly and she was treated with hemodialysis, transfusion and subsequently systemic corticosteroid. Anti-phospholipid antibody was positive to lupus anti-coagulant and the titer was normalized after 2-month steroid therapy at which time the visual outcome differed between the eyes. The right eye showed improvement in visual acuity and visual field, but the left eye was not improved and retained a central scotoma. SLE needs to be considered in young women with optic neuritis when other causes of optic neuritis have been excluded, and serologic tests including anti-phospholipid antibody should be conducted.

Percutaneous transthoracic fine needle aspiration(PCNA) and biopsy(PCNB) are well-accepted methods for thediagnosis of various intrathoracic lesions. Implantation of cancer cells along the needle tract is one of therarest complications of these techniques, but was found along the needle tract in a patient who underwent PCNB forlung cancer.

PURPOSE: We evaluated the feasibility of extracting pure left ventricular blood pool and myocardial time-activity curves (TACs) and of generating factor images from human dynamic N-13 ammonia PET using factor analysis. The myocardial blood flow (MBF) estimates obtained with factor analysis were compared with those obtained with the user drawn region-of-interest (ROI) method. MATERIALS AND METHODS: Stress and rest N-13 ammonia cardiac PET imaging was acquired for 23 min in 5 patients with coronary artery disease using GE Advance tomograph. Factor analysis generated physiological TACs and factor images using the normalized TACs from each dixel. Four steps were involved in this algorithm: (a) data preprocessing; (b) principal component analysis; (c) oblique rotation with positivity constraints; (d) factor image computation. Area under curves and MBF estimated using the two compartment N-13 ammonia model were used to validate the accuracy of the factor analysis generated physiological TACs. The MBF estimated by factor analysis was compared to the values estimated by using the ROI method. RESULTS: MBF values obtained by factor analysis were linearly correlated with MBF obtained by the ROI method (slope=0.84, r=0.91). Left ventricular blood pool TACs obtained by the two methods agreed well (Area under curve ratio: 1.02 (0~1 min), 0.98 (0~2 min), 0.86 (1~2 min)). CONCLUSION:: The RESULTS of this study demonstrates that MBF can be measured accurately and noninvasively with dynamic N-13 ammonia PET imaging and factor analysis. This method is simple and accurate, and can measure MBF without blood sampling, ROI definition or spillover correction. KW: N-13 ammonia, PET, Myocardial blood flow, Factor analysis

Gastrointesinal polyp is a premalignant lesion, it is recommanded to be removed. Endoscopic polypectomy has long been considered as a safe and effective method for removal of polyps. One hundred forty eight endoscopic gastrointestinal polypectomy were done in 111 patients who visited Chungnam National University Hospital from January in l991 to August in l993, and clinical character including histopathology were evaluated.
