概括
用质子或光子进行乳房切除术后放射治疗 (PMRT) 对立即乳房重建 (IBR) 显示出良好的结果. 预防性Mepitel膜的使用减少了IBR患者的手术部位感染和重新手术.
科学领域:
- 在瘤学瘤学.
- 整形外科 整形外科 整形外科
- 放射治疗 物理 物理
背景情况:
- 乳房切除术后的立即乳房重建 (IBR) 是一个常见的程序.
- 乳腺切除术后的放射治疗 (PMRT) 对于患有晚期乳腺癌的患者来说通常是必要的.
- 需要进一步调查PMRT对IBR结果的影响,特别是比较质子和光子疗法.
研究的目的:
- 评估乳房切除术后放射治疗 (PMRT) 对立即乳房重建 (IBR) 结果的影响.
- 在接受IBR的患者中比较质子和光子放射治疗之间的结果.
- 为了确定手术部位感染 (SSI),未计划的重新手术和PMRT后重建失败的风险因素.
主要方法:
- 对接受乳腺切除术,IBR和PMRT的患者进行了回顾性分析.
- 包括231名妇女,包括放射治疗类型 (质子与光子),分化和手术结果的数据.
- 用于评估SSI,再手术和重建失败的风险因素的单变量和多变量Cox模型.
主要成果:
- 两年的累积风险:SSI 17.83%,计划外的重新手术 16.19%,重建失败 7.60%.
- 预防性梅皮特膜使用显著减少了SSI (HR:0.35) 和无计划的重新手术 (HR:0.39).
- 胸壁或淋巴结增强与重建失败的风险增加有关 (单变分析).
结论:
- 大多数患者通过PMRT获得成功的IBR结果,无论是质子或光子疗法.
- 虽然SSI和重新运行率很高,但重建失败率很低.
- 降低SSI和Mepitel Film的重新运营费率需要进一步调查.

Pneumothorax-II
1.7K
Pneumothorax is a medical condition defined by the buildup of air in the pleural space between the lungs and the chest wall. This accumulation of air can lead to partial or complete lung collapse, resulting in a range of clinical manifestations. Understanding the clinical presentation and effective management strategies is crucial for healthcare professionals in providing timely and appropriate care to individuals with pneumothorax.

Radiological Investigation III: Pulmonary Angiogram and PET Scan
722
Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Diagnosing and managing appendicitis requires a structured and comprehensive approach that spans from initial assessment to postoperative care. Here is an overview of the process:
Diagnosing Appendicitis
It requires a multifaceted approach, starting with a detailed physical examination to pinpoint the location and nature of the pain and identify any associated symptoms. Laboratory tests play a crucial role. A complete Blood Count (CBC) typically reveals leukocytosis (an increased number of...
