Non-pharmacologic approach to pediatric constipation

Functional constipation (FC) is a pervasive problem in pediatrics. Although pharmaceuticals are commonly used for FC, parents and patients show reluctance or find dissatisfaction with available medications at times. Further, patients often have interest in utilizing nutraceutical supplements and botanicals that are available over the counter. This literature review aims to summarize research studies performed on non-pharmacologic approaches to constipation and to evaluate the safety and efficacy of these modalities. Overall data on non-pharmacologic treatments for childhood constipation were sparse, and though some studies were available for adult populations, pediatrics studies were generally limited, lacking or flawed. Certain supplements, such as prebiotics, probiotics and fiber, are safe and are without significant side effects. Though fiber supplements such as glucomannan, green banana mass, cocao husk and various fiber blends have emerging evidence in children, evidence for psyllium, cellulose and flaxseed only have supportive studies in adults. Other than senna, studies of botanicals indicate significant safety concerns (in particular with Aloe vera with aloin and Cascara sagrada) and insufficient evidence. For patients with a significant behavioral or anxiety component to their FC and exhibit dyssynergia, mind-body interventions (e.g. diaphragmatic breathing, biofeedback, cognitive behavioral therapy, and behavioral modifications) are certainly safe and effective. Finally, movement and manipulative interventions such as abdominal massage, reflexology, acupuncture and transcutaneous nerve stimulation show promise in the field of pediatric constipation, and data is accumulating for efficacy. These modalities require further study to determine mechanisms of action and which populations may benefit the most from these therapies.

人为提高儿童肱骨髁上骨折外侧克氏针出针点的可行性及置针经验分析

目的初步探讨人为提高儿童肱骨髁上骨折外侧克氏针出针点的可行性及其相应的置入方法。方法本研究分为两个阶段。第一阶段:收集2016年3月至2016年12月中国医科大学附属盛京医院161例儿童伸直型肱骨髁上骨折外侧针构型病例术中透视图像中最外侧针的出针点和入针点位置,测量最外侧针冠状面和矢状面钢针角度。第二阶段(2017年1月至2017年12月)基于第一阶段的研究结果,由中国医科大学附属盛京医院两名小儿骨科医生尝试人为提高最外侧针的出针位置(预期组),另外两名外科医生继续按照常规流程置针(对照组),对两组各项治疗参数进行比较。结果第一阶段参与回顾性研究的161例患者中,47例(29.2%)最外侧针出针点位于骨干-干骺端交界区(metaphyseal-diaphyseal junction,MDJ)上边界线以上,其中40例最外侧针(85.1%)由肱骨小头骨化中心(ossific nucleus of the capitellum,ONC)外侧或骨化中心外1/3置入(正位像),于骨化中心后1/3或骨化中心后方置入(侧位像)。冠状面和矢状面钢针平均角度分别为58.4°和90.5°。第二阶段,预期组中有47例(65.3%,47/72)患者的最外侧针出针点位于MDJ上边界线以上,而对照组中仅32例(36%,32/89)出针点位于MDJ上边界线以上。两组比较差异有统计学意义(χ2=16.134,P<0.05)结论在单纯外侧针构型中,人为提高最外侧针出针点可行。钢针路径位于正位像肱骨小头骨化中心外侧、外1/3及侧位像在肱骨小头后方或后1/3位置时更容易获得高位的出针点。

新疆心脑血管疾病治疗费用核算与住院费用影响因素分析

目的 综合分析新疆心脑血管疾病总治疗费用现状，为医疗资源的合理配置提供理论依据。方法 通过多阶段分层随机抽样，收集2017年新疆心脑血管疾病患者样本信息。在SHA 2011框架下，采用自上而下的分摊方法，核算心脑血管疾病的治疗费用。建立线性回归模型，用以分析住院费用的影响因素。结果 心脑血管疾病总治疗费用达105.74亿元；占比67.22%的治疗费用发生在综合医院；排名前三位的疾病分别为冠心病、高血压和脑梗塞，占比达74.20%；65岁及以上老年人群花费占比为43.51%；县（区）级机构（t = - 218.362，P＜0.001）、市级机构（t = - 103.65，P＜0.001）、住院天数（t = 233.297,P＜0.001）、65岁以上人群（t = 58.422，P＜0.001）、手术情况（t = 101.514，P＜0.001）均是影响住院费用的主要因素。结论 新疆心脑血管疾病消耗大量医疗资源；防控工作重点关注老年人群；治疗费用机构流向有待优化，应强化基层医疗机构在防治慢病工作中的主导作用；缩短住院时间是有效控制治疗费用的直接途径。     

Milestones in the discovery of hepatitis C

The discovery of hepatitis C has been a landmark in public health as it brought the opportunity to save millions of lives through the diagnosis, prevention and cure of the disease. The combined work of three researchers, Alter H, Houghton M and Rice C, which set the basis for the diagnosis, treatment and prevention of hepatitis C apart from laying the ground work for a new approach to study infections in general and developing new antiviral agents. This is a story of a transfusion-associated infection. A series of clinical studies demonstrated the existence of an infectious agent associated with hepatitis. That was followed by the identification of what was later known to be the hepatitis C virus (HCV) and the development of diagnostic tests. It all preceded the full molecular identification and demonstration of a causal effect. Finally it ended up with the development and discovery of a new class of therapeutic drugs, the direct acting antivirals, which are now used not only to cure the disease but most probably, to eliminate the problem. This work started with Dr Alter H who demonstrated that a new virus was responsible for the majority of post-transfusion hepatitis followed by Houghton M who cloned the virus and developed the blood test to identify those cases that carried the virus. Finally, the work of Rice C demonstrated that a cloned HCV produced after applying molecular biology techniques could cause long-standing infection and cause the same disease as the one observed in humans.     

Gastrectomía vertical como técnica quirúrgica en cirugía bariátrica: análisis de resultados de seguridad y efectividad

IntroductionThe aim of this study is to evaluate the safety and effectiveness results of sleeve gastrectomy as a bariatric technique.MethodsObservational follow-up study of a cohort of patients who underwent sleeve gastrectomy in our center between 2008 and 2017. A total of 223 patients were included: 166 as a primary technique (group 1) and 57 as a hypothetical first stage (group 2).ResultsIn group 1, the postoperative morbidity is 12.6%, with a fistula rate of 4.2%; 5.4% required reoperation and mortality was 0.6%. In group 2, postoperative morbidity is 14%, with a fistula rate of 5.3%; 10.5% required reoperation and mortality was 5.3%. In group 1, 79.6% and 62.5% of patients at 2 and 5 years respectively managed to achieve a % EBMIL>50%. In group 2, the second stage was completed only in 8 patients (14.0%). Of the patients who did not complete the second stage, 32.2% and 5.9% achieved a % EEBMIL>100% at 2 and 5 years. Analyzing those who completed the second stage, the mean EEBMIL% was 90.5% and 93.4% at 2 and 5 years.ConclusionsSleeve gastrectomy is a safe technique in patients with BMI<45 and effective in terms of weight loss in the short-medium term. In patients with BMI>55, a preoperative optimization aimed at reducing morbidity and mortality is necessary, as well as adequately planning the second stage, without which it is clearly insufficient.
