腹腔镜手术与开腹手术治疗异位妊娠比较研究

目的：探讨腹腔镜手术治疗与开腹手术治疗异位妊娠的临床疗效对比。方法：选择近5年来腹腔镜与开腹手术治疗66例异位妊娠病例,根据实施手术的方式把患者分为观察组36例,和对照组30例,进行全方位比照分析情况分析。结果：腹腔镜组术后自主排尿时间、术后住院时间患者康复时间,均明显短于开腹组,差异常显著性（P〈0.001）。腹腔镜组手术时间也短于开腹组（P〈0.05）。结论：腹腔镜手术治疗异位妊娠手术安全,具有手术时间短,创伤小,术后恢复快,住院时间短等优点,值得推广。     

Inferior alveolar and mental nerve injuries associated with open reduction and internal fixation of mandibular fractures: A Seven Year retrospective study

PurposeTo document adverse neurosensory changes in the inferior alveolar nerve (IAN) and mental nerve (MN) after surgical mandibular fracture treatment and to identify risk factors associated with these changes.Materials and methodsA retrospective study of patients surgically treated for mandibular fractures. The primary study variable was the postoperative change in IAN/MN neurosensory examination after fracture fixation. Risk factors were categorized as demographic, anatomic, experience of the operator, fracture displacement and number of miniplates placed at each fracture site. Appropriate statistics were computed.Results209 patients with 293 fractures were analysed. One hundred twenty fractures (41%) were located between the lingula and mental foramen, and 173 fractures (59%) were located distal to the mental foramen. Two hundred seventeen (41%) were displaced by 5 mm or more. In 38 fractures (13%), the IAN/MN neurosensory status worsened after treatment. In a multivariate model, fracture displacement, operator inexperience and two plate fixation were associated with a statistically significant risk (P ≤ 0.05) for postoperative deterioration of IAN/MN sensation.ConclusionFixation with two miniplates, fracture displacement of 5 mm or more and operator inexperience were associated with an increased risk for deterioration of the IAN/MN neurosensory status after treatment of mandibular fractures.     

SHR、WKY大鼠与SD大鼠注意缺陷多动障碍模型行为学特征的比较

目的 比较SHR、WKY、SD大鼠行为学特征，探寻研究SHR大鼠注意缺陷多动障碍（ADHD）理想的对照模型。方法 运用旷场实验统计大鼠运动距离、运动速度、穿格数及理毛次数来评价SHR、WKY、SD大鼠自主运动情况；运用水迷宫实验检测三组大鼠的学习记忆能力。结果 旷场实验结果显示，SHR大鼠在总运动量、平均运动速度及穿格次数上较WKY及SD大鼠均显著增加（P<0.01）；与WKY大鼠相比，SD大鼠运动距离显著高于WKY组（P<0.01），其运动速度及穿格数略高于WKY组（P<0.05）；水迷宫隐匿站台实验中，与SHR大鼠相比，SD大鼠潜伏期较长（P<0.05），在潜伏期运动距离上，SD大鼠在训练第1天、第3天及第4天运动距离较SHR大鼠延长（P<0.05或P<0.01）；比较WKY组，SD大鼠潜伏期及潜伏期运动距离较WKY在各个训练时间均有不同程度的下降（P<0.05或P<0.01）。在空间探索阶段，SD大鼠穿台次数及目标象限运动时间、距离比率等均较SHR大鼠有所减少（P<0.05），而较WKY大鼠则有不同程度的升高（P<0.05或P<0.01）。结论 WKY大鼠与SHR大鼠行为学差异过大，两者的比较存在一定的不足，增设SD大鼠作为SHR大鼠的对照组能够提升SHR大鼠行为学特征的可比性，更为客观的反映SHR大鼠的行为学特征。     

腹腔镜手术治疗103例非腹腔型隐睾

目的探讨腹腔镜手术对于非腹腔型隐睾的治疗优势。方法回顾性研究2004年1月至2009年1月所收治的103例非腹腔型隐睾患儿(腹腔镜手术45例,传统开放手术58例)的住院及随访资料,比较两种手术方式手术时间、术中出血量、术后住院时间及术后并发症等各项临床指标的差异。结果两组在手术时间、术中出血量及并发症等方面差异均有统计学意义(P<0.05),腹腔镜组比开放式手术组手术时间短、术中出血少、术后恢复快、住院时间短,双侧隐睾不需增加切口。结论治疗非腹腔型隐睾腹腔镜手术与传统开放式手术相比具有较明显优势,可替代传统开放手术作为首选手术方式。     

The burden of predatory journal and congress requests in foot and ankle surgery

IntroductionIn recent years the proportion of predatory invitations by email of the total number of emails received has grown dramatically. The aim of the current study was to objectify the increase in predatory journal and congress requests per email over a 5.5-year period and their relatedness to the receivers’ speciality in Foot and Ankle surgery.Material and methodA comprehensive Microsoft Outlook^® analysis of 5.5 years’ worth of junk email from one surgical Foot & Ankle specialist working at a Level-1 trauma centre was evaluated. The topic of each email from the last year was scored according to the ‘degree-of-relatedness’.ResultsBetween July 1^st 2013 and December 31^th 2018 a total of 41,687 emails were collected in the junk email folder of Microsoft Outlook^®. A total of 17.0 percent was attributed to emails from predatory journals and congresses. Over the 5.5-year period the percentage of total emails that consisted of invitations from predatory journals and congresses rose from 4.5% to 40.8%. Only an insignificant amount (2.3%) was directly related to the authors medical sub-speciality of Foot and Ankle surgery.ConclusionThis is the first study showing the individual burden of unsolicited emails from predatory publishers and journals. The authors acknowledge the risk that this publication, like all others, will likely result in yet even more invitations from predatory journals and congress invitations. All should be warned of a huge increase in emails from predatory journals and congresses, which has likely not peaked yet. Appropriate action is needed, as we urge foot–ankle interested scientists to publish in indexed journals with proper peer review.     

The heavy price of conversion from laparoscopic to open procedures for emergent cholecystectomies

Background

Laparoscopic cholecystectomy (LC) is the standard operative intervention for gallbladder disease. Complications may necessitate conversion to an open cholecystectomy (OC). This study aims to determine the cost-consequences of laparoscopic-to-open conversion using a nationally-representative sample.
