乳腺癌前哨淋巴结活检的研究进展

目的总结乳腺癌前哨淋巴结活检（SLNB）的研究现状和进展。方法复习近年来国内外的相关文献,对乳腺癌SLNB的概念、适应证、活检技术、提高检出准确率的方法、病理学检查方法、转移灶类型、临床应用等进行综述。结果 SLNB的适应证在不断扩大。示踪剂、影像学检查和病理学检查技术的发展有助于对乳腺癌前哨淋巴结（SLN）状态的评估。乳腺癌SLNB的操作方法还没有统一的标准,对其能否指导选择性的腋窝淋巴结清扫的争议较大,且SLNB的SLN检出率及假阴性率变化范围较大。结论 SLNB已成为乳腺癌外科治疗的重要辅助手段,但其操作尚需进一步规范,其临床应用范围还需要大量前瞻性、多中心的随机试验进一步论证。     

MAPK信号通路在骨关节炎发病机制中的研究进展

丝裂原活化蛋白激酶（mitogen—activated proteinkinase,MAPK）真核细胞信号传递的重要途径之一,在调节控制细胞结构和功能活动中发挥关键作用。在真核生物中MAPK信号通路包括p38、ERK、JNK、ERK5等多个亚家族。随着研究的不断深入,发现p38、ERK、JNK信号转导途径的活化与骨关节炎（osteoarthritis,OA）软骨损伤密切相关,诱导软骨细胞产生基质金属蛋白酶,加速关节软骨病理性降解,并参与软骨细胞增殖、凋亡与分化等一系列反应,明确MAPK信号通路在OA中的发生发展机制已成为研究的新热点。     

Distally based perforator flaps for reconstruction of post-traumatic defects of the lower leg and foot. A review of the anatomy and clinical outcomes

Study aims

To report the surgical anatomy of the perforator arteries at the lower leg, analyse clinical outcomes in previous studies, and forward methodological recommendations for future studies of post-traumatic perforator flap reconstructions.

Methods

A study sample of 640 human patients drawn from 24 clinical reports was included for review. The sample comprised of four subsets: sural flap reconstructions (n = 257), saphenous flaps (n = 122), supramalleolar flaps (n = 92), and propeller flaps (n = 169).

Results

Statistical analysis of samples from anatomical studies documents significant differences in the perforator distribution from the tibial and peroneal artery; peroneal perforator arteries are randomly organised whereas tibial artery perforators are clustered at three definite levels. The failure rates in clinical studies ranged from 0% to 6%, being lowest for supramalleolar flap reconstructions and highest for saphenous flaps; however, differences between the four subsets were not statistically significant at the 95% confidence level. Due to methodological flaws, outcome comparisons in the actual study sample should be interpreted cautiously; in most clinical studies both risk variables and outcome indicators are poorly defined. The outcome of Dynamic Infrared Thermography imaging of post-transposition changes of flap perfusion is reported.

Summary

Fasciocutaneous perforator flaps seem to have high survival rates and represent a feasible approach to post-traumatic reconstructions, especially in low-resource settings. A template for data gathering is recommended for higher accuracy in future comparative studies, and for scientific analysis of success and risk factors. New imaging techniques indicate a promising potential of micro-circular angiogenesis during the first two weeks after flap transpose.

A primer for workers' compensation

Background contextA physician's role within a workers' compensation injury extends far beyond just evaluation and treatment with several socioeconomic and psychological factors at play compared with similar injuries occurring outside of the workplace. Although workers' compensation statutes vary among states, all have several basic features with the overall goal of returning the injured worker to maximal function in the shortest time period, with the least residual disability and shortest time away from work.PurposeTo help physicians unfamiliar with the workers' compensation process accomplish these goals.Study designReview.MethodsEducational review.ResultsThe streamlined review addresses the topics of why is workers' compensation necessary; what does workers' compensation cover; progression after work injury; impairment and maximum medical improvement, including how to use the sixth edition of American Medical Association's (AMA) Guides to the evaluation of permanent impairment (Guides); completion of work injury claim after impairment rating; independent medical evaluation; and causation.ConclusionsIn the “no-fault” workers' compensation system, physicians play a key role in progressing the claim along and, more importantly, getting the injured worker back to work as soon as safely possible. Physicians should remain familiar with the workers' compensation process, along with how to properly use the AMA Guides.

Micropapillary bladder cancer: Current treatment patterns and review of the literature

ObjectivesNo guidelines exist for the management of micropapillary bladder cancer (MPBC) and most reports of this variant of urothelial carcinoma are case series comprising small numbers of patients. We sought to determine current practice patterns for MPBC using a survey sent to the Society of Urologic Oncology (SUO) and to present those results in the setting of a comprehensive review of the existing literature.Materials and methodsA survey developed by the Translational Science Working Group of the Bladder Cancer Advocacy Network–sponsored Think Tank meeting was distributed to members of the SUO. The results from 118 respondents were analyzed and presented with a literature review.ResultsMost survey respondents were urologists, with 80% considering bladder cancer their primary area of interest. Although 78% of the respondents reported a dedicated genitourinary pathologist at their institution, there were discrepant opinions on how a pathologic diagnosis of MPBC is determined as well as variability on the proportion of MPBC that is clinically significant. Among them, 78% treat MPBC differently than conventional urothelial carcinoma, with 81% reporting that they would treat cT1 MPBC with upfront radical cystectomy. However, the respondents had split opinions regarding the sensitivity of MPBC to cisplatin-based chemotherapy, which affected utilization of neoadjuvant chemotherapy in muscle-invasive disease.ConclusionsThe management of MPBC is diverse among members of the SUO. Although most favors early cystectomy for cT1 MPBC, there is no consensus on the use of neoadjuvant chemotherapy for muscle-invasive MPBC.     

Evaluation of Non Diseased Specified Outcome Measures in Hand Injuries to Assess Activity and Participation Based on ICF Content

The objective of the study is to provide information about non disease specified outcome measures which evaluate disability in patients who have impairments in hand and upper extremity and to find the extent to which they are evaluating “disability” based on ICF hand Core Set (activity limitation and participation restriction). MEDLINE, CINAHL, GOOGLE SCHOLAR , OVID and SCIENCE DIRECT databases were systematically searched for studies on non disease specified outcome measures used to evaluate upper extremity function; only studies written in English were considered. We reviewed titles and abstracts of the identified studies to determine whether the studies met predefined eligibility criteria (eg, non disease specified out come measures used in hand injured patients). All the outcome measures which had eligibility included. After full text review ,7 non disease specified outcome measures in hand were identified. Studies were extracted, and the information retrieved from them. All the outcome measures which had incuded, were linked with ICF hand core set disability part (activity and participation). All of them only linked to 16 (42 %) components of ICF hand Core Set, which were most activity and less participation from ICF. None of the non disease specified out come measures in hand injuries cover all domains of disability from the ICF Hand Core Set.
