Insulinoma is the most frequent endocrine tumor of the pancreas and the first of the endocrine-secreting tumor of the gut to be recognized by Nicholls in 1902. Recurrent episodes of hypoglycemia is the main cause of the symptoms and signs which were sweating, pallor, dizziness, habitual change, convulsion and coma. In 1935, Whipple and Frants were described so-called “Whipple's triad”: the patient's symptoms occur with fasting or exercise; at the time of symptoms, the serum glucose in 50mg/dl or less; and the symptoms are relieved by the administration of glucose. While these criteria were timely, they proved to be rather nonspecific and may be found in other conditions that result in fasting hypoglycemia. We experienced a 44-year-old female patient who had repeated attacks of convulsion, unconsciousness and coma for 3 years. Although she has been treated with anticonvulsant, the symptoms and signs were not disappeared. At the time of administration, she was a full coma state due to hypoglycemia and was dramatically reversed by intravenous administration of the glucose solution. The preoperative test such as provocative test, abdominal CT and celiac angiography revealed insulinoma and after enucleation the pathologic diagnosis was the same. We like to report an adult female patient with insulinoma and the review of literatures briefly.

Hemangiopericytoma is a rare vascular tumor arising from pericytes. The tumor usually develops in the skin or subcutaneous tissue, particularly in the extremities.4 pulmonary origin of hemangiopericytoma is known to be quite rare. It has the potential to become a highly malignant lesion, so wide excision is the treatment of choice. We present a case of primary malignant hemangiopericytoma of the lung and discuss the clinical symptoms, diagnosis, therapy and prognosis within the context of a brief review.

PURPOSE:It is important to evaluate the healing process of avascular necrosis (AVN) involving femoral head after treatment. The purpose of this study was to assess the usefulness of pinhole bone scintigraphy in the AVN of femoral head after surgery. MATERIALS AND METHODS: We analyzed the changing pattern of pinhole bone scintigram in 21 femoral heads of 16 patients (14 lesions/11 male, 7 lesions/5 female, mean age: 39.4 yrs) before and after multiple drilling or vascularized bone grafting for AVN of the femoral head. In all patients, pre-operative scintigrams were obtained at 1 to 3 months before treatment and the first post-operative scintigrams were obtained at 1 to 3 months after treatment. All patients were followed for 2 to 4 years after operation. RESULTS: The findings of the pinhole scintigrams were divided into three patterns: 1) curvilinear, 2) scattered spotty and 3) undetermined. The 10 of 11 lesions with curvilinear pattern had good postoperative clinical and radiological follow-up findings. However, all 6 lesions with scattered spotty pattern showed poor postoperative findings, which necessitated total hip joint replacement. Of the 4 lesions with undetermined pattern, 2 required total hip joint replacement. There was significant difference in postoperative prognosis between the curvilinear and scattered spotty patterns (p<0.05). CONCLUSION: We conclude that the pattern of pinhole bone scintigram obtained within 1 to 3 months after multiple drilling or vascularized bone graft operation is a useful prognostic indicator in the AVN of femoral head.

Local control is the important prognostic factor in cancer treatment because local control decrease the relative risk of metastatic spread and increse distant metastasis free survival. IORT is the modality which could increase local control without incressing complication, combined with curative operation. Eventhough we could achieve significant deacreased local failure by IORT and curative resection, it should not be committed as a main treatment modality without proving acceptable complications. Therapeutic Radiology Department of Yeungnam University Medical Center have tried 58 IORT from June 15, 1988, and performed 53 IORT in patients with gastric cancer. No local failure has been reporte? by regular follow up so far. Nine cases(17%) of treatment related complifaiton were reported including intestinal obstrution, hemorrhage, sepsis, and bone marrow depression. These complications could be comparable to Jo's 25.2% (chemotherapy + operation), Kim's 18% (chemotherapy only in inoperable patients), because our treatment regimen is consisted of IORT (1500 cGy), external irradiation(--4500 cGy) and extensive chemotherapy (FAM, 5FU+MMC, BACOP). Our data encouraged us to re-inforce further IORT in stomach cancer treatment.

Reflex sympathetic dystrophy (RSD) is a common rheumatic disorder manifesting painful swelling, discoloration, stiffening and atrophy of the skin. Radiographic alterations include small, spotty subperiosteal bone resorption (SBR) and diffuse porosis, and MR imaging shows bone and soft-tissue edema. The purposes of current investigation were to assess 99mTc HDP pinhole SPECT (pSPECT) findings of RSD, to correlate them with those of radiography and MRI and to speculate about causative mechanism of SBR which characterizes RSD. pSPECT was performed in five patients with RSD of the foot. pSPECT showed small, discrete, spotty hot areas in the subperiosteal zones of ankle bones in all five patients. Diffusely increased tracer uptake was seen in the retrocalcaneal surface where the calcaneal tendon inserts in two patients with atrophic RSD. pSPECT and radiographic correlation showed spotty hot areas, that reflect focally activated bone turnover, to closely match with SBR. Further correlation with MRI showed both spotty hot areas and SBR to coincide in location with the insertions of ligaments and tendons, onto which pulling strain is constantly exerted. In contrast, the disuse osteoporosis in unstrained bones did not show any more significantly increased tracer uptake than normal cancellous bones.

The most proper antibiotic must be selected after antimicrobial susceptibility test. If difference in antimicrobial susceptibility was significant between oral sampling sites, it is rationale to use the most susceptible antibiotic agent respond to dental procedure and object of treatment. This study examined sampling site variation from saliva, supragingival plaque and subgingival plaque of 16 children's oral microbes. The cultured bacterial isolates, which were Streptococcus viridans and Neisseria, were examined for 10 antimicribial drugs with the Bauer-Kirby agar disk diffusion method. The used drugs were Penicillin, Ampicillin, Oxacillin, Cephalothin, Imipenem, Gentamicin, Erythromycin, Vancomycin, Ciprofloxacin, Clindamycin. There was no significant difference between three sampling sites for antimicrobial susceptibility test of S. viridans and Neisseria and the sequence of susceptibility was agreed among them. In conclusion, it was suggested that antimicrobial susceptibility test from saliva, supragingival plaque and subgingival plaque of children have no significant sampling site variation.

PURPOSE: We report on a novel method and outcomes of laparoscopic gastric tubing with pyloromyotomy. METHODS: The abdominal procedure includes laparoscopic gastric mobilization, celiac axis lymph node dissection, formation of the gastric tube, and pyloromyotomy. Between January 2009 and April 2013, our minimally invasive esophagectomy (MIE) was performed on 54 patients with esophageal cancer. The short-term outcomes, including postoperative complications, were analyzed. RESULTS: There were no cases of conversion to open surgery. Of 54 patients, 52 patients had squamous cell carcinoma (SCC) and two had adenocarcinoma. The total operative time was 349.8+/-77.4 minutes, of which 90.6+/-27.6 minutes was required for the abdominal procedure. The mean estimated operative blood loss during the abdominal procedure was 40.0+/-355.5 ml. The postoperative complication rate was 24.1%; three patients died of pneumonia. CONCLUSION: Laparoscopic gastric tubing with pyloromyotomy is a feasible and safe treatm ent option for patients with esophageal cancer.

PURPOSE: We evaluated the usefulness of 24 hour/3 hour radio-uptake ratio, lesion to non-lesion ratio, in differentiating bony metastases from acute (<2 months) and healing ( 2 months) fractures. MATERIALS AND METHODS: Sixty-three patients (age range: 26-81, 32 males, 31 females) having 90 lesions (30 bone metastases, 30 acute fractures, 30 healing fractures) were included. Bone scans were obtained 3 and 24 hours after administration of 740 MBq of 99mTc-MDP. The ratio of radio-uptake in the lesion to normal area was measured as 24/3 hour radio-uptake ratio ([lesion/non-lesion RUR at 24 hour]/[lesion/non-lesion RUR at 3 hour], 24/3 RUR) and analyzed clinical significance in differentiating bone metastases from acute or healing fractures. RESULTS: Mean 24/3 RUR were 1.22+/-0.18 for bone metastases, 1.25+/-0.14 for acute fractures, and 0.99+/-0.15 for healing fractures. 24/3 RUR values of bone metastases and acute fractures were not significantly different. But 24/3 RUR values of bone metastases and healing fractures, and those of acute and healing fractures were found to be significantly different (p<0.001). When 24/3 RUR of 1.0 was considered as the cut off point separating metastases from fracture, a sensitivity of 100% (30/30) was obtained. The specificity was 0% (0/30) in separating metastases from acute fractures, and 47% (14/30) in separating metastases from healing fractures. When 24/3 RUR of 1.2 was considered as the cut off point, sensitivity of 53% (16/30) in the diagnosis of bone metastasis, and specificity of 37% (11/30) in separating metastases from acute fractures, and 100% (30/30) in separating metastases from healing fractures were obtained. CONCLUSION: 24/3 RUR is useful in differentiating bone metastases from healing fractures, but not in differentiating bone metastases from acute fractures. A 24/3 RUR of less than 1.0 suggests healing fractures. A 24/3 RUR of more than 1.2 suggests bone metastases or acute fractures.
