Juvenile spinal AVM consists of an abnormal tangle of vessels fills the spinal cord at involved levels. Contains neural parenchyma within the nidus of the AVM and is fed by mult ple medullary arteries. We report a case of juvenile spinal AVM treated with conventional radiation therapy instead of embolization or surgery because of its location(from C-2 to C-7) and multiple feeding arteries.

It is generally known that moyamoya disease is a disease showing typical angiographic findings such as bilateral stenosis or occlusion of the distal internal carotid arteries and the major branches with extensive parenchymal, leptomeningeal or transdural anastomosis. However, its etiology is still unknown. Chief clinical manifestations are transient ischemic attack, motor paresis, headache, altered mentality and seizure. Twelve angiographically proven cases of moyamoya disease in chonnam National University Hospital from 1983 to 1990 were analyzed with respect to clinical manifestations, findings of brain computed tomography, cerebral angiographic findings and outcomes. The results were as follows: 1) Sex ratio was 1:2 as 4 males to 8 females. 2) They were 2 juvenile form(aged 8-13 yrs) and 10 adult form(aged l9-59 yrs). 3) Transient ischemic attack(2 cases), hemiparesis (5 cases), headache(6 cases), altered mentality(4 cases), facial palsy(2 cases), aphasia(1 case) and neck stiffness(1 case) were shown as clinical anifestations. 4) In brain computed tomography, intraventricular hemorrhage(5 cases), intracerebral emorrhage(2 cases), subarachnoid hemorrhage(1 case), infarction(4 cases including 2 old infarction combined with hemorrhage), contrast enhanced tortuous moyamoya vessels only in brain base(1 case) and suprasellar tumor(1 case) were noted. 5) Brain magnetic resonance imaging was perfomed in 1 case. It revealed characteristic collateral vessels in brain base. 6) All cases showed the characteristic angiographic findings of moyamoya disease with different stage of the progression, In addition to moyamoya vessels, 2 cases of aneurysm and 1 case of diffuse internal carotid artery hypoplasia were found. 7) Some neurologic sequales were noted in two cases. One case expired due to recurret intraventricular hemorrhage.

Background: By analyzing small bowel capsule endoscopy (SBCE) performed in two large hospitals in Kazakhstan, we aimed to explore the characteristics of patients representative of Central Asia and the technical characteristics of SBCE. Methods: SBCE cases were retrospectively analyzed. A descriptive analysis was conducted on the patients’ demographic data, diagnosis, and clinical symptoms. The results of SBCE, such as the lesions found, transit time and retention rate in the stomach and small bowel, and bowel visualization quality, were analyzed. Complications related to SBCE were investigated. Results: SBCE was performed in 123 patients. Abdominal pain (81.3%) and chronic diarrhea (66.7%) were the most common symptoms, followed by weight loss (25.2%) and gastrointestinal bleeding (15.4%). The most common disease was Crohn’s disease (52.0%). Definite lesions, such as ulcers, polyps, and bleeding, were identified in 55.3% of patients. SBCE was successfully completed in all cases except for 11 (9.1%). The average small bowel transit time was 4 hours and 28 minutes. Excellent visualization (>75% of mucosa) was reported in 82.5% of patients. No patients experienced complications. Conclusions SBCE performed in Kazakhstan showed a high diagnostic yield with high-quality patient selection and no complications.

BACKGROUND AND OBJECTIVES: We assessed the ability of portable echocardiography (with contrasts) to clearly delineate the cardiac structure, and evaluated the impact of its use on the diagnosis and management of critically ill patients in Korea. SUBJECTS AND METHODS: We prospectively enrolled 123 patients (mean age 66+/-16 years), who underwent portable transthoracic echocardiography (with contrast) for image enhancement at 12 medical centers. The quality of the global left ventricular (LV) images, the number of the regional LV segments visualized, the ability to visualize the LV apex and the right ventricle (RV), and any changes in the diagnostic procedure and treatment strategy were compared before and after the contrast. RESULTS: Of the 123 patients, 52 (42%) were using mechanical ventilators. The amount of poor or uninterpretable images decreased from 48% to 5% (p<0.001), after the contrast. Before the contrast, 15.6+/-1.1 of 16 LV segments were seen, which improved to 15.9+/-0.6 segments (p=0.001) after the contrast. The ability to visualize the LV apex increased from 47% to 94% (p<0.001), while the inability to clearly visualize the RV decreased from 46% to 19% (p<0.001). Changes in the diagnostic procedure (for example, not requiring other types of imaging studies) were observed in 18% of the patients, and the treatment plan (medication) was altered in 26% of patients after the contrast echocardiography. CONCLUSION: The use of a contrast agent during the portable echocardiography, in intensive care settings, can improve the image quality and impact the diagnostic procedures and treatment for Korean patients.

Purpose: The clinical significance of margin status in pancreatic head cancer is still controversial due to the nonstandardized definition of R status and pathologic reporting. This study aims to evaluate the impact of the margin status including location and the role of radiation therapy in pancreatic head cancer. Methods: A total of 314 patients who underwent curative-intent surgery for pancreatic head cancer between 2010 and 2017 were analyzed. Demographics, survival, and local recurrences were compared according to 2 definitions: 0-mm R1 as direct involvement and 1-mm R1 as close resection margin less than 1 mm. The specific margins were divided into 4 groups according to the location around the pancreas: pancreas transection, anterior surface, posterior surface, and vessel (superior mesenteric artery/superior mesenteric vein) margin. Results: The 0-mm R1-rate was 15.6%, and increased to 36.3% in 1-mm R1. The median overall survival rate of 0-mm R0 vs. R1 was 26 months vs. 16 months (P = 0.052) and that of 1-mm R0 vs. R1 was 27 months vs. 18 months, respectively (P = 0.016). In individual margins, posterior, anterior surface, and pancreas transection margin involvement were associated with poor outcome, and the 1 mm posterior surface involvement was an independent risk factor for disease-free survival (hazard ratio, 1.63). Adjuvant radiation therapy had oncologic benefits, especially in R1 patients (P = 0.011) compared to R0 patients (P = 0.088). Conclusion Margin status, especially 1-mm R1 status is an important predictive factor, and involved posterior surface has a clinical impact. Patients with positive margins should be considered adjuvant radiation therapy.

Opisthorchis viverrini infection was found to be highly prevalent in 3 riverside villages (Ang Svay Chek A, B, and C) of the Prey Kabas District, Takeo Province. This area is located in the southern part of Cambodia, where the recovery of adult O. viverrini worms was recently reported. From May 2006 until May 2010, fecal examinations were performed on a total of 1,799 villagers using the Kato-Katz thick smear technique. In the 3 villages, the overall positive rate for helminth eggs ranged from 51.7 to 59.0% (av. 57.4%), and the percentage positive for O. viverrini was 46.4-50.6% (47.5%). Other helminths detected included hookworms (13.2%), echinostomes (2.9%), Trichuris trichiura (1.3%), Ascaris lumbricoides (0.6%), and Taenia spp. (0.06%). The prevalence of O. viverrini eggs appeared to reflect a lower infection in younger individuals (<20 years) than in the adult population (>20 years). Men (50.4%) revealed a significantly higher (P=0.02) prevalence than women (44.3%). The Ang Svay Chek villages of the Prey Kabas District, Takeo Province, Cambodia have been confirmed to be a highly endemic area for human O. viverrini infection.
