Effect of corneal stromal pocket irrigation in small-incision lenticule extraction

ObjectivesTo investigate the effect of corneal stromal pocket irrigation after small-incision lenticule extraction (SMILE) on visual acuity, intraocular pressure (IOP), corneal parameters and complications after surgery.MethodsA total of 242 eyes of 121 patients undergoing SMILE were enrolled in this prospective controlled study, and it was designed for one eye to randomly undergo SMILE with balanced salt solution irrigation of the corneal stromal pocket, while the other eye was not. The uncorrected distance visual acuity (UDVA) and slit lamp examination were recorded at 1 hour, 1 day, 1 week, and 1 month. Postoperative corneal density, corneal biomechanical, corneal endothelial cell number, and anterior OCT images were compared at 1 day, 1 week, and 1 month.ResultsCompared with the nonirrigation group, the irrigation group showed significantly higher UDVA at 1 day postoperatively (P < 0.05), but there was no significant difference during the rest of the postoperative period (1 hour, 1 week, and 1 month). In addition, no significant differences were found in IOP, corneal density, corneal biomechanics, corneal endothelial cells, and corneal morphology. No visual decline or severe postoperative complications were found in the patients in this study.ConclusionsInterlamellar irrigation did not affect IOP, corneal parameters, morphology, complications, or UDVA at 1 hour, 1 week, and 1 month after the operation, but it may promote UDVA 1 day after the operation.Subject terms: Refractive errors, Outcomes research, Surgery     

Rupture of the long head of the biceps brachii tendon near the musculotendinous junction in a young patient: A case report

We report an unusual case of the long head of the biceps brachii tendon rupture near the musculotendinous junction in a young patient. The injury occurred in a young athlete during sports competition. The clinical presentation, surgical treatment, and technique with tenodesis using a unicortical button of the ruptured tendon were presented. The post-surgical recovery was uneventful, and the patient returned to sports in 6 mo. The treatment approach and surgical technique of the long head of biceps brachii rupture was reviewed and discussed. In conclusion, surgical treatment of the long head of the biceps brachii tendon rupture with unicortical button tenodesis resulted in a favorable outcome in a young athlete.     

听神经瘤术后面神经功能损伤危险因素分析

目的分析影响听神经瘤患者术后短期及长期面神经功能的危险因素。 方法回顾性分析厦门大学附属第一医院神经外科自2015年1月至2018年6月收治的62例听神经瘤患者的临床资料。于术后7 d及术后6个月对所有患者的面神经功能进行评估。收集可能与患者术后早期及长期面神经功能障碍存在相关性的因素，采用Logistic单因素与多因素回归对相关因素与患者术后短期及长期面神经功能的关系进行分析。 结果术后7 d，21例（33.9%）患者面神经功能正常，41例（66.1%）患者出现面神经功能损伤；术后6个月，49例（79.0%）患者面神经功能为正常，13例（21.0%）患者面神经功能损伤。Logistic单因素回归分析结果显示：肿瘤最大直径越大、肿瘤与面神经黏连越紧密，患者术后7 d发生面神经功能损伤的可能性越大（P=0.002、0.002）；术前临床症状持续时间为患者术后6个月面神经功能障碍的危险因素（P=0.035）。Logistic多因素回归分析结果显示：肿瘤与面神经的黏连程度、肿瘤最大直径为患者术后7 d面神经功能障碍的独立危险因素（P=0.003、0.014）；术前临床症状持续时间、肿瘤最大直径为患者术后6个月面神经功能障碍的独立危险因素（P=0.010、0.030）。 结论肿瘤与面神经的黏连越紧密、肿瘤最大直径越大，患者术后7 d发生面神经功能损伤的可能性越大。患者术前临床症状持续时间越长、肿瘤最大直径越大，术后6个月发生面神经功能损伤的可能性越大。     

住院双相障碍与精神分裂症患者自知力水平的保护性因素

目的 探讨住院双相障碍与精神分裂症患者自知力水平及其保护性因素。方法 在广州市4家精神科住院部连续入组符合《国际疾病分类（第10版）》（ICD-10）双相障碍或精神分裂症诊断标准的患者465例。采用自编人口学及临床特征问卷、自知力与治疗态度问卷（ITAQ）进行调查，比较不同自知力水平患者的人口学和临床特征，采用两分类Logistic回归分析探讨自知力的保护因素。结果 年龄小（OR=0.977）、男性（OR=1.705）、曾经结婚或同居（OR=1.677）、诊断为双相障碍（OR=2.185）、最近一个月有悲观厌世（OR=2.663）、每天睡眠时间≥7小时（OR=1.620）、每周运动1~2次（OR=1.770）是住院双相障碍和精神分裂症患者自知力的保护因素。结论 住院双相障碍和精神分裂症患者自知力水平与多种人口学特征及临床特征相关。     

3D打印在功能性鼻整形手术中的应用

功能性鼻整形手术是一种恢复或改善鼻的形状和功能的手术,在术中常用到植入或非植入性材料。3D打印是材料制造行业的一次技术革新,近年来在包括生命医学的多个科学领域发展迅猛。3D打印具有个性定制、精确制作的特点,这恰好与个体化需求明显的功能性鼻整形手术契合。本文就3D打印在功能性鼻整形手术术前规划和学习、术中辅助操作和引导、植入物等方面的研究和应用进行综述,并将应用3D打印与传统方法的功能性鼻整形手术进行对比,同时展望3D打印在该领域的未来发展。
