We report the case of a 34-year-old woman with severe post-infectious gastroparesis who was transferred from an outside medical facility for a second opinion regarding management. This patient had no prior history of gastrointestinal symptoms. However, in the aftermath of a viral illness, she developed two months of intractable nausea, vomiting, and oral intake intolerance that resulted in numerous hospitalizations for dehydration and electrolyte disturbances. A solid-phase gastric emptying scan had confirmed delayed emptying, confirming gastroparesis. Unfortunately, conventional pro-kinetic agents and numerous anti-emetic drugs provided little or no relief of the patient’s symptoms. At our institution, the patient experienced a cessation of vomiting, reported a significant reduction in nausea, and tolerated oral intake shortly after taking mirtazapine. Based on mirtazapine’s primary action as a serotonin (5-HT) 1a receptor agonist, we infer that this receptor system mediated the clinical improvement through a combination of peripheral and central neural mechanisms. This report highlights the potential utility of 5-HT1a agonists in the management of nausea and vomiting. We conclude that mirtazapine may be effective in treating symptoms associated with non-diabetic gastroparesis that are refractory to conventional therapies.

Endoscopic ultrasound (EUS) has become an essential tool for the study of pancreatic diseases. Specifically, EUS plays a pivotal role evaluating patients with a known or suspected pancreatic mass. In this setting, differential diagnosis remains a clinical challenge. EUS-guided fine-needle aspiration (FNA) and fine-needle biopsy (FNB) have been proven to be safe and useful tools in this setting. EUS-guided FNA and FNB, by obtaining cytological and/or histological samples, are able to diagnose pancreatic lesions with high sensitivity and specificity. In this context, several methodological features, trying to increase the diagnostic yield of EUS-guided FNA and FNB, have been evaluated. In this review, we focus on the role of rapid on-site evaluation (ROSE). From data reported in the literature, ROSE may increase diagnostic yield of EUS-FNA specimens by 10%-30%, and thus, diagnostic accuracy. However, we should point out that many recent studies have reported adequacy rates of > 90% without ROSE, indicating that, perhaps, at high-volume centers, ROSE may not be indispensable to achieve excellent results. The use of ROSE can be considered important during the learning curve of EUS-FNA, and also in hospital with diagnostic accuracy rates < 90%.

AIM： To evaluate the diagnostic accuracy of histological evaluation of pancreatic tissue samples obtained by a modified method for recovering and processing the endoscopic ultrasound （EUS）-guided fine needle aspiration （FNA） material in the differential diagnosis of pancreatic solid masses. METHODS： Sixty-two consecutive patients with pancreatic masses were prospectively studied. EUS was performed by the linear scanning Pentax FG-38UX echoendoscope. Three FNAs （22G needle） were carried out during each procedure. The materials obtained with first and second punctures were processed for cytological study. Haterials of the third puncture were recovered into 10% formol solution by careful injection of saline solution through the needle, and processed for histological study. RESULTS： Length of the core specimen obtained for histological analysis was 6.5±5.3 mm （range 1-22 mm）. Cytological and histological samples were considered as adequate in 51 （82.3%） and 52 cases （83.9%）, respectively. Overall sensitivity of both pancreatic cytology and histology for diagnosis of malignancy was 68.4%. Conbary to cytology, histology was able to diagnose tumours other than adenocarcinomas, and all cases of inflammatory masses. Combination of cytology and histology allowed obtaining an adequate sample in 56 cases （90.3%）, with a global sensitivity of 84.21%, specificity of 100% and an overall accuracy of 90.32%. The complication rate was 1.6%.CONCLUSION： Adequate pancreatic core specimens for histological examination can be obtained by EUS-guided FNA. This technique is mainly useful for the diagnosis of different types of pancreatic tumours and evaluation of benign diseases.

本研究旨在调查顾客对奥罗米亚保险公司(OIC)人寿保险购买态度。为此,该研究的目的是调查顾客对购买人寿保险政策的态度,哪些因素显着影响购买者对购买人寿保险政策的态度,以及衡量经济和社会人口因素之间的关系和顾客对于人寿保险购买政策的态度。原始数据通过问卷收集。调查问卷分发给74名购买OIC人寿险保单样本客户,其中只有71人完成并退回。多元回归模型(MRM)方法被用来分析和测试变量之间的关系。研究发现,宗教,性别,婚姻状况,性别和职业地位等因素对奥罗米亚保险公司的寿险保单持有人的态度具有显着影响,但其他因素如教育,年龄和薪水对消费者对人寿保险购买政策的态度影响不显著。奥罗米亚保险公司可以利用本研究发现的有关影响人寿保险购买政策态度的社会人口和经济因素进行进一步研究来衡量所采用的营销策略的有效性。本研究主要采用卡方检验独立性检验(α=0.05),根据受访者的数据和检验结果,本研究发现人口因素在不同程度上对顾客购买人寿保险的态度有一定的影响。特别是购买者的年龄、教育程度、收入水平和工作状态等都会对人们购买人寿保险的态度在不同程度上产生显着影响。意外的性行为,除穆斯林宗教外的宗教信仰以及买家所拥有的财务支持都证明对购买者购买人寿保险态度没有显著影响。

Active lifestyle and qualitative and quantitative diets are the best way to lose weight. In our study we have assessed the effectiveness and tolerability of a soluble powder rich in fibers and at low glycemic index and used, with a portion of fresh fruit, as replacement meal (for a total calorie intake ranging from a minimum of about 130 kcal to a maximum of 260 kcal) in 52 overweight/obese subjects of the outpatient clinic of the Italian National Research Council (CNR) of Rome already in treatment with a low-fat low-carbohydrates qualitative diet. The study was a parallel, prospective trial of two randomized sample groups, “intervention” (26 subjects) and “control” (26 subjects). After 8 weeks, the treatment based on the replacement meal has improved the results obtained through the qualitative diet alone above all in the overweight subjects: 11/16, versus only 2/16 in the control group, became ranged within normal weight. On the contrary, the majority of obese subjects didn’t change their BMI classification suggesting that, in case of obesity, a controlled quantitative correction with weighing food portions could be a better strategy than low-calorie replacement meal.

Supratentorial cortical ependymoma is a rare primary brain tumor in adults. Only 50 cases are reported in the literature including pediatric and adult patients. We report a 30-year-old male with sensory-type seizures who was found to have a right posterior frontal cortical lesion with large cystic component. The lesion was resected completely and histopathology and immunohistochemistry examinations confirmed anaplastic ependymoma WHO grade III. The patient received radiotherapy treatment post-surgery, and he was tumor free one year after treatment.
