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.

Esophageal carcinoma is a rare malignant neoplasm consisting of about 1.5% of the whole gastrointestinal tract neoplasm and has poor prognosis of which survival rate is below 5%. The squamous cell carcinoma of the esophagus could be multicentric in character and may have occured in 9.5-27% of incidence. The most common site is head and neck region. The metastasis of esophageal carcinoma occur through hematogenous, lymphatic spread, direct invasion and rarely intramural metastasis. Of theses, intramural metastasis has been occured in 7-14.3% of incidence and its presence has been regared to poor prognostic factor due to early regional or distant metastasis. Surgery, chemotherapy, radiotherapy alone or combination of these has been used as treatment modalities of esophageal cancer, but combination chemoradiotherapy with or without operation is prefered method than other at present. Authors report a case of esophageal carcinoma showing intramural metastasis to the gastric wall, which had the complete remission with preoperative chemoradiotherapy.

PURPOSE: The objective of this study was to comparatively assess the bone regenerative capacity of absorbable collagen sponge (ACS), biphasic calcium phosphate block (BCP) and collagenated biphasic calcium phosphate (CBCP) loaded with a low dose of recombinant human bone morphogenetic protein-2 (rhBMP-2). METHODS: The CBCP was characterized by X-ray diffraction and scanning electron microscopy. In rabbit calvaria, four circular 8-mm-diameter defects were created and assigned to one of four groups: (1) blood-filled group (control), (2) rhBMP-2-soaked absorbable collagen sponge (0.05 mg/mL, 0.1 mL; CS group), (3) rhBMP-2-loaded BCP (BCP group), or (4) rhBMP-2-loaded CBCP (CBCP group). The animals were sacrificed either 2 weeks or 8 weeks postoperatively. Histological and histomorphometric analyses were performed. RESULTS: The CBCP showed web-like collagen fibrils on and between particles. Greater dimensional stability was observed in the BCP and CBCP groups than in the control and the CS groups at 2 and 8 weeks. The new bone formation was significantly greater in the BCP and CBCP groups than in the control and CS groups at 2 weeks, but did not significantly differ among the four groups at 8 week. The CBCP group exhibited more new bone formation in the intergranular space and in the center of the defect compared to the BCP group at 2 weeks, but a similar histologic appearance was observed in both groups at 8 weeks. CONCLUSIONS: The dose of rhBMP-2 in the present study enhanced bone regeneration in the early healing period when loaded on BCP and CBCP in rabbit calvarial defects.
