Systematic review of acceptability,cardiovascular, neurological,bone health and HRT outcomes following risk reducing surgery in BRCA carriers

Primary surgical prevention in the form of risk-reducing salpingo-oophorectomy (RRSO) is the most effective option and the gold standard for ovarian cancer (OC) risk-reduction, particularly given the absence of an effective national OC screening programme. However, premenopausal RRSO leads to premature surgical menopause with detrimental long-term health sequelae particularly in women who do not/are unable to take hormone replacement therapy (HRT). HRT uptake in women undergoing pre-menopausal oophorectomy appears low and is dependent on informed counselling, the safety of HRT and efficacy in mitigating the health sequelae of premature menopause. Acceptance of a central role for the fallopian tube in OC etiopathogenesis, coupled with the detrimental consequences of premature menopause, has led to the attractive proposal of early-salpingectomy with delayed oophorectomy as an alternative OC surgical prevention strategy in premenopausal women who have completed childbearing but decline or wish to delay RRSO. The successful implementation of risk reducing surgery for OC prevention depends on the acceptability of surgery to both, recipients (e.g. BRCA1/BRCA2 carriers) and intervention deliverers (healthcare professionals/researchers). Acceptability is also informed by an understanding of health outcomes following risk reducing surgery and the safety of HRT. It is therefore vital to understand the effects of surgery on important health outcomes such as cardiovascular health, neurological function and bone health. We present a comprehensive review of acceptability, the selected health outcomes mentioned above and HRT safety following risk reducing surgery.     

经乙状窦后道上结节入路切除岩斜区脑膜瘤

目的 探讨经乙状窦后道上结节入路切除岩斜区脑膜瘤的手术技巧、疗效及适应证。方法 回顾性分析2016年5月—2019年3月采用该入路切除的15例岩斜区脑膜瘤患者的临床特征、手术方法及术后并发症。结果 15例术前均表现头痛、5例面部感觉减退、2例面部疼痛、1例听力下降。SimpsonⅡ级切除11例，Ⅲ级切除3例，Ⅳ级切除1例。平均随访15个月，无死亡，术后远期生活质量评估（KPS）评分80~90分。术后头痛15例均缓解，面部感觉减退3例缓解、2例加重、新增2例，面部疼痛2例缓解，听力下降1例未缓解，新增复视2例、6个月后均缓解。结论 掌握好适应证，经乙状窦后道上结节入路是切除岩斜脑膜瘤的较好途径。     

目标教学在前列腺超声诊断技术带教中的应用价值研究

目的探讨目标教学在前列腺超声诊断技术带教中的应用效果。方法选择2017年1月-2018年12月于我院进行前列腺超声诊断技术培训的影像学专业学生80例,根据入院时间先后顺序分为研究组与对照组,每组40例。对照组医学生采用常规教学法带教,研究组医学生采用目标教学法带教,比较两组带教效果。结果研究组医学生的超声诊断仪使用(94.12±2.73)分、超声扫查技巧(92.81±5.06)分、操作技能(90.83±5.11)分、超声图像表现掌握(91.96±3.67)分均高于对照组(P<0.05)。研究组医学生的总体满意度CEQ评分(8.22±0.24)分高于对照组的(5.25±0.30)分,两组比较差异具有统计学意义(P<0.05)。结论目标教学在前列腺超声诊断技术带教中的应用效果良好,可有效提高医学生的操作能力,提高医学生对带教模式的肯定度。     

How to stich? 90 degrees: The perfect angle

ObjectiveThis is a discussion about correct suturing techniques and implications that follow inappropriate suturing. We deconstruct the suturing needle angles and methods to be adopted to acquire the perfect needle angle to the tissue being sutured. A study of angles confirms that 90° is perceptible to the naked eye and easy to identify, making it an appropriate foundation to explain, communicate and teach the concepts in the wet-lab and the operating room.BackgroundThere is a lack of robust teaching regarding entry of the needle orthogonal to the tissue planes. In addition, objective methods of assessing angles of the needle relative to the tissue and consequences of inaccuracy are lacking. The authors aim to deconstruct the steps of suturing with the aim of demonstrating ninety degrees is the perfect suturing angle.Study designWe conducted a study to identify 90° (the perfect suturing angle) as an angle easy to identify with the naked eye. Angles from 86° to 94° and 41° to 49° were printed and presented to volunteers with the instruction to identify the angles of 90° and 45°.ResultsFifty-one volunteers replied to the 90° angle study and sixty-five volunteers replied to the 45° study. 92% correctly identified at least one 90° angle and 72% identified both the 90° angles. 63% identified at least one 45° angle and only 27% identified both the 45° angles presented to them. This supported our hypothesis that 90° is an angle that is readily identifiable to the human eye.ConclusionsObjective assessment of surgical skills and training should focus on the basic needle skills with particular emphasis on suturing angles, progressing to higher skills using low and intermediate fidelity models and correlating practice alongside the trainees' operative progress.
