The posterior meningeal artery (PMA) usually originates from the third segment of the vertebral artery. Many variations in its origin and course have been observed;however, as far as we know, the association of true aneurysm of the PMA and its anomalous origin from the internal carotid artery has not been reported previously. We reported the case of a 59-year-old woman who suddenly presented a loss of consciousness without head trauma, computed tomography (CT) revelated intracerebellous hematoma associated with a subarachnoid hemorrhage of the posterior cerebral fossa. Cerebral angiography demonstrated a true aneurysm of the PMA which originated from the internal carotid artery.

Background/purpose: Noninvasive assessment of esophageal varices (EVs), their size and bleeding stigmata may reduce endoscopic burden, cost and drawbacks. We aimed to evaluate the diagnostic performance of noninvasive fibrosis scores (AAR, APRI, FIB-4, King and VITRO scores) in predicting the presence of EVs and high risk varices needing treatment (VNT) in HCV-related cirrhosis of Egyptian patients. Methods: This prospective study included 154 HCV-related advanced compensated cirrhotic patients with no history of bleeding who underwent screening endoscopy for EVs. AAR, APRI, FIB-4, King and VITRO scores were assessed. Results: Esophageal varices were found in 120 patients (77.9%) and VNT in 92 patients (59.7%). Apart from AAR, all scores demonstrated statistically significant correlations with the presence and the size of EVs. Using area under receiver operating characteristic curve (AUC), these scores were good predictors for the presence of EVs and VNT, where VITRO score had the highest AUC (0.920 and 0.900) and accuracy (97.1% and 87%), sensitivity (75, 82.6%), specificity (100, 93.5%), PPV (100, 95%) and NPV (53.2, 78.4%) with cutoffs >1.3 and >1.8 respectively. Conclusion: Noninvasive fibrosis scores can predict the presence of EVs and VNT. VITRO score was the best predictor with higher accuracy for clinical applicability than studied scores.

Spontaneous cholecystocutaneous fistula is a rare complication of chronic calculous cholecystitis, because currently gallstones are diagnosed and treated at an early stage. This occurrence is possible even if it seems actually to be rare. We report a case of spontaneous cholecystocutaneous fistula of Anterior Abdominal Wall with subcutaneous gallstones admitted in the medical oncology unit of HASSAN II University Hospital. An 64-year-old woman, presented with a large subcutaneous abscess in the right subcostal area with swelling. An abdominal computed tomography scan showed a subcutaneous gallstone and communication between the abscess and the gallbladder. Cholecystectomy was performed and the abdominal wall abscess was drained externally. This case report demonstrates that maintaining a high degree of suspicion of this rare entity is helpful in achieving correct preoperative diagnosis, and that computed tomography scan should be performed in all cases of unexplained abdominal wall suppuration.

屈服应力是高浓度非牛顿膏体的关键流变参数,是膏体充填输送系统设计的基础。工程应用中采用塌落度这一经验参数评判其流动性,却无法获取准确的屈服应力参数值。通过构建圆柱和圆锥2种理论模型并利用模型与流变仪的测试结果对比,明确塌落度与屈服应力的反比例关系;通过模型计算屈服应力,在较低屈服应力,圆柱比圆锥模型计算结果准确。尾砂膏体塌落度试验表明增大塌落筒的尺寸可以提高模型计算结果的准确性。添加胶结剂的塌落度试验,因胶结剂的物理化学作用,颗粒间产生絮网结构形成悬浊液,料浆更加均质,却增加了料浆的内摩擦力,屈服应力升高。不同粗砂比的塌落度试验显示:因添加的粗颗粒降低了物料整体的比表面积,物料吸附水的能力下降,使大量水分子由吸附态转变为游离态,增强料浆的可流动性使料浆屈服应力显著降低。

Background and objective: The aim of this study was to evaluate the association between dietary intake and bone mineral density in children with juvenile idiopathic arthritis (JIA). Methods: A cross-sectional study carried out in Morocco between May 2010 and June 2011, covering out patients with JIA. The characteristics of patients were collected. The nutritional status was assessed by a food questionnaire including data of food intake during 7 consecutive days using 24-hour dietary recall. Food intake was quantified using the software Bilnut (Bilnut version 2.01, 1991). Bone mineral density (BMD in g/cm2) was measured by DXA method (X-ray absorptiometry) on a Lunar Prodigy. Results: The study consisted of 33 patients with JIA (4 - 16 years old). The median age of patients was 10.4 ± 4.3 years. Median disease duration was 2 (1 - 4.5) years. The group of patients with low dietary intake of proteins was associated with low BMD (p = 0.03). Low BMD was related with low intake of magnesium (p = 0.007) and vitamin C (p = 0.04) in children aged between 4 and 9 years. Low intake of vitamin E and folate was associated with high BMD in the other range of children (p < 0.001). Conclusion: This study suggests that low intake of protein and of some micronutrients (magnesium, vitamin C, vitamin E and folate) influence bone mass in children with JIA. Prospective studies with a larger number of patients seem to be necessary in order to confirm our findings.
