Advantages of an Anterior-Based Muscle-Sparing Approach in Transitioning From a Posterior Approach for Total Hip Arthroplasty: Minimizing the Learning Curve

BackgroundEnthusiasm for anterior-based approaches for total hip arthroplasty (THA) continues to increase but there is concern for increased complications during the learning curve period associated. This study aimed to investigate if there was a difference in perioperative variables, intraoperative and immediate postoperative complications, or patient-reported outcomes when transitioning from a mini-posterior approach (mPA) to an anterior-based muscle-sparing (ABMS) approach for THA.MethodsRetrospective cohort study on the first 100 primary THA cases (n = 96 patients) of the senior author (August 2016 to August 2017) using the ABMS approach. These cases were compared to primary THA cases done the year prior (July 2015 to July 2016, n = 91 cases in 89 patients) using an mPA. Data were extracted and analyzed via gamma regression with robust standard errors and using generalized estimating equation regression.ResultsWe found no difference in the estimated blood loss (P = .452) and surgical time (P = .564) between the cohorts. The ABMS cases had a slightly shorter length of stay (P = .001) with an adjusted mean length of stay of 1.53 days (95% confidence interval 1.4-1.6) compared to 1.85 days (95% confidence interval 1.8-1.9) in the mPA cases. There was no difference in the frequency of immediate postoperative complications (all, P > .05). There was no difference in the adjusted mean change in patient-reported outcomes (all P > .05). In the ABMS group, there was no difference in surgical time or physical function computerized adaptive test between the first 20 cases (reference) and each subsequent group of 20 cases (all P > .05).ConclusionThis study demonstrates no associated learning curve for an experienced senior surgeon when switching routine THA approach from mPA to ABMS. We advise careful interpretation of our results, as they may not apply to all surgeons and practices.Level of EvidenceLevel III Therapeutic Study: retrospective comparative study.     

造口肉芽肿两种治疗方法疗效比较

目的观察在造口门诊用硝酸银、电灼两种治疗方法对造口肉芽肿的治疗效果。 方法造口门诊对就诊的52例造口肉芽肿患者，随机分成硝酸银组和电灼组，分别用硝酸银、电灼两种方法进行治疗，观察并分析其疗效。 结果两种治疗方法疗效比较差异无统计学意义（Z=1.646，P=0.100）。有效率回归分析电灼比硝酸银更有效。 结论两种治疗方法对造口肉芽肿均有效，可根据肉芽肿的大小、患者是否方便复诊等情况，选择适当的处理方法，以达到满意的治疗效果。     

Nutrition in pregnancy

Many pregnant women rely on their health professional for nutrition information during routine antenatal visits. This review offers information to assist health professionals with advising pregnant women of the important nutrition considerations during pregnancy. The roles of some of the key nutrients are discussed, including folic acid, iodine, iron, calcium, and vitamin D. Recommendations for each of the key nutrients are covered and examples of how these can be achieved are presented. The review also details additional nutritional considerations that should be discussed during antenatal consults, including energy balance and weight gain recommendations, the importance of food safety during pregnancy, the recommended safe levels of consumption of vitamin A, caffeine, and fish, and the importance of abstaining from alcohol. Educating and supporting women during pregnancy to make healthy food choices to fulfil their needs and the needs of their growing fetus, will help to promote a healthy start to life.     

Inpatient Versus Outpatient Arthroplasty: A Single-Surgeon,Matched Cohort Analysis of 90-Day Complications

Background

Although some prior work supports the safety of same-day arthroplasty performed in a hospital, concerns remain when these procedures are performed in a free-standing ambulatory surgery center. The purpose of this study is to compare 90-day complication rates between matched cohorts that underwent inpatient vs outpatient arthroplasty at an ambulatory surgery center.

Fístulas posquirúrgicas de líquido cefalorraquídeo tras cirugía transesfenoidal de adenomas hipofisarios: análisis de una serie de 302 intervenciones

IntroductionTranssphenoidal surgical removal is the preferred treatment of most pituitary adenomas. Postoperative cerebrospinal fluid (CSF) leakage is the leading cause of morbidity after this procedure, with an incidence rate that varies from 0,5-15% in the main published series.ObjectivesThe primary objective of this study was to establish the incidence of postoperative CSF leakage in a sample of surgeries performed at the University Hospital of La Ribera by the same surgical team. The secondary objectives were to: ascertain the distinctive features between patients with and without postoperative CSF leakage, identify risk factors for their development, evaluate the relationship between the surgical technique for closing the sella turcica and the onset of postoperative CSF leakage and evaluate different treatment regimens for this complication.MethodsThe data of 302 consecutive transsphenoidal surgical procedures for pituitary adenoma removal which were performed between 1999 and 2017 were retrospectively reviewed.Results and conclusionsThe incidence of postoperative CSF leakage in our series was 2,3% (in accordance with similar published studies). It was possible to correlate intraoperative CSF leakage with two variables: pituitary macroadenoma and tumors with suprasellar extension (P < .005). This correlation did not exist for postoperative CSF leakage. We found a statistically significant correlation between intraoperative and postoperative CSF leakage (P < .005). Due to the low incidence of postoperative CSF leakage in our series, it was not possible to identify risk factors for its development.     

Ocular complications of severe corneal abrasions after cosmetic blepharopigmentation

A 53-year-old woman with hemiparesis and poor dexterity, underwent cosmetic blepharopigmentation on the both upper eyelids in the dermatology clinic of a private hospital. She was not asked for any information on her medical history and no informed consent was obtained and the procedure was performed without any protective ocular shields. The patient experienced severe lacrimation, discomfort, and increased sensitivity to light during and after the procedure. She also noticed blurred vision after the procedure. Ophthalmologic examination revealed tender and oedematous eyelids and corneal abrasions in both of her eyes. Topical antibiotics and preservative-free lubricants were able to recover her from her signs and symptoms at 1-week follow-up. It is recommended that cosmetic blepharopigmentation should be applied cautiously with patient’s informed consent after obtaining a thorough medical history and with protective ocular shields to avoid potential complications.     

应用腹腔镜技术治疗阑尾残端瘘5例分析

正阑尾残端瘘是阑尾切除术后严重的并发症之一,其发生率在0.7%～3.7%~([1]),一旦发生,往往不能自愈,治疗周期长,给病人带来严重的身心损害和经济负担。研究认为,70%～80%的病人能够通过冲洗引流、肠内肠外营养支持、内镜下阑尾残端夹闭等方法治愈,但仍有近20%的病人在接受3～6个月的保守治疗仍无法治愈,须接受二次手术~([2])。笔者医院将腹腔镜技术应用于阑尾残端瘘病人的再次手术中。现报告如下。
