左氧氟沙星为基础的三联疗法根除幽门螺旋杆菌的疗效探讨

目的：探讨左氧氟沙星为基础的三联疗法根除幽门螺旋杆菌的临床治疗效果。方法方便选择2013年9月—2015年3月期间该院收治的120例Hp感染者作为实验对象，随机数字表法将患者分为对照组（n=60例）和观察组（n=60例），对照组采用标准三联法治疗，观察组采用以左氧氟沙星为基础的三联疗法治疗，观察两组患者Hp根除情况及恶心呕吐、腹部不适等不良反应发生情况。结果观察组Hp根除率显著高于对照组，差异有统计学意义（P<0.05），观察组总不良反应发生率为8.33%（5/60)，对照组总不良反应发生率为13.33%（8/60)，观察组不良反应发生率低于对照组，差异不具有统计学意义（P>0.05）。结论 Hp患者采用以左氧氟沙星为基础的三联疗法治疗，临床疗效较好，能够有效提高Hp根除率，并且不良反应发生率低，安全可靠，值得临床推广使用。     

阿奇霉素序贯给药辅助治疗小儿大叶性肺炎的效果及对患儿血清炎症因子水平的影响

目的探讨阿奇霉素序贯给药辅助治疗小儿大叶性肺炎的效果及对患儿血清炎症因子水平的影响。方法回顾性分析我院2014年10月至2019年10月收治的120例大叶性肺炎患儿的临床资料,根据治疗方式的不同将其分为对照组(60例,阿奇霉素静脉滴注治疗)和观察组(60例,阿奇霉素序贯给药治疗)。比较两组的治疗效果、不良反应情况、血清炎症因子及肺功能指标水平。结果观察组的治疗总有效率显著高于对照组,不良反应总发生率显著低于对照组(P<0.05)。治疗后,两组的TNF-α、PCT、IFN-γ、TM水平均降低,FVC、TLC、Cdyn水平均升高,且观察组显著优于对照组(P<0.05)。结论阿奇霉素序贯给药辅助治疗小儿大叶性肺炎的效果显著,可有效改善患儿血清炎症因子水平和肺功能指标水平,降低不良反应发生率,值得临床推广应用。     

Cardiac-type total anomalous pulmonary venous return is not benign

ObjectiveThe objective of this study was to investigate the association between morphological variation and postsurgical pulmonary vein (PV) stenosis (PPVS) in patients with cardiac total anomalous pulmonary venous connection (TAPVC).MethodsThis single-center, retrospective study included 168 pediatric patients who underwent surgical repair of cardiac TAPVC from 2013 to 2019 (connection to the coronary sinus [CS], n = 136; connection directly to the right atrium [RA], n = 32). Three-dimensional computed tomography modeling and geometric analysis were performed to investigate the morphological features; their relevance to the PPVS was examined.ResultsThe connection type had no association with PPVS (CS type: 18% vs right atrial type: 19%; P = .89) but there was a higher incidence of PPVS in patients with a single PV orifice than > 1 orifice (P < .001). Confluence-to-total PV area ratio (hazard ratio, 4.78, 95% CI, 1.86-12.32; P = .001) and length of drainage route (hazard ratio, 1.22; 95% CI, 1.14-1.31; P < .001) had a 4- and 1-fold increase in the risk for PPVS in the CS type after adjustment for age and preoperative pulmonary venous obstruction. In the right atrial type, those with anomalous PV return to the RA roof were more likely to develop PPVS than to the posterior wall of the RA (P < .001).ConclusionsThe number of inter-junction PV orifice correlated with PPVS development in cardiac TAPVC. The confluence-to-total PV ratio, length of drainage route, and anomalous PV return to the RA roof are important predictors for PPVS. Morphological subcategorization in this clinical setting can potentially assist in surgical decision-making.     

Factors influencing choice of medical vs. surgical treatment of pediatric appendicitis

PurposeTo examine what proportion of caregivers, if given a choice, would choose medical versus surgical treatment of appendicitis and what factors would be important in their decision.MethodsA survey was devised and given to the caregivers of children presenting to the pediatrician for a routine visit in community and academic pediatric clinics. The survey presented a summary of outcomes after medical (non-operative) and surgical treatment of uncomplicated appendicitis. Participants were then asked to choose medical versus surgical treatment if their child were to develop appendicitis. They were also asked to rate the importance of certain factors in their decision ? 1 being “not important” and 5 being “very important”.ResultsFour hundred surveys were distributed with an 86.2% (345/400) response rate. Six percent (21/342) of respondents reported a history of appendicitis and 49.4% (168/340) reported having known someone who had appendicitis. The majority of respondents, 85.3% (284/333), were mothers. A minority of respondents, 41.7% (95% CI: 36.7, 47.0), chose medical treatment over surgery for appendicitis. There was no statistical difference in the proportion of mothers (41.6%) versus fathers who chose medical treatment (41.3%). Caregivers who chose medical treatment were more likely to rate time in hospital (p = .008) and time out of school (p = 05) as important in decision making when compared with those who chose surgery. Those who chose surgical treatment were more likely to rate risk of recurrent appendicitis (p < .001) as important to decision making. In the multivariate analysis, those who rated time in hospital as very important had more than twice the odds of choosing medical therapy (OR 2.20, p = 0.02) when compared with those who rated it as less important. Not knowing someone who has had appendicitis was significantly associated with choosing medical therapy when compared with those who do know someone who has had appendicitis, OR 2.3, p = .002. Rating pain as very important was also significantly associated with choosing medical therapy, when compared to those rating pain 1–3, OR 3.38, p = .03.ConclusionsIn this survey of caregivers of children presenting for routine care, 41.7% would choose medical, or non-operative, therapy for their children with acute appendicitis. The risk of recurrence, time in hospital, and time out of school, pain, and knowing someone who has had appendicitis were all important factors that families may consider when making a decision. These data may be useful for surgeons counseling patients on which treatment to pursue.     

Cuantificación y tratamiento de la congestión en insuficiencia cardíaca: una visión clínica y fisiopatológica

Renal sodium and water retention with resulting extracellular volume expansion and redistribution are hallmark features of heart failure syndromes. However, congestion assessment, monitoring, and treatment represent a real challenge in daily clinical practice. This document reviewed historical and contemporary evidence of available methods for determining volume status and discuss pharmacological aspects and pathophysiological principles that underlie diuretic use.
