Birt‐Hogg‐Dubé syndrome‐associated renal cell carcinoma: Histopathological features and diagnostic conundrum

Birt‐Hogg‐Dubé (BHD) syndrome is associated with the development of hereditary renal cell carcinoma (RCC) and is caused by a germline mutation in the folliculin gene. Most cases of BHD syndrome‐associated RCC (BHD‐RCC) are less aggressive than sporadic clear cell RCC and multifocal. Therefore, it is critical to distinguish BHD‐RCC from its sporadic counterparts to identify and monitor affected families and to preserve renal function for as long as possible. The World Health Organization/International Society of Urological Pathology consensus classification defined distinct entities for certain hereditary RCC; however, BHD‐RCC was not included in this classification. Although the clinical features and molecular mechanisms of BHD‐RCC have been investigated intensively over the last two decades, pathologists and urologists occasionally face difficulties in the diagnosis of BHD‐RCC that require genetic testing. Affected patients usually have miscellaneous benign disorders that often precede renal carcinogenesis. In the present review, we summarize the current understanding of the histopathological features of BHD‐RCC based on our epidemiological studies of Japanese families and a literature review. Pathological diagnostic clues and differential diagnosis of BHD‐RCC from other hereditary RCC are also briefly discussed.

Ospemifene plus fractional CO2 laser: a powerful strategy to treat postmenopausal vulvar pain

Abstract

This study is a single-center, retrospective analysis of postmenopausal women presenting with dyspareunia and vulvar pain, aiming to evaluate relative effectiveness of vestibular CO₂ laser therapy as a treatment. Three monthly sessions of laser were performed to each patient and thereafter a three-months follow-up was stablished. A total number of 72 patients undergoing vestibular laser treatment were recruited from patient files in the period between 2016 and 2018. Among these, 39 women also received a concomitant treatment with ospemifene (60?mg/day) during the study period. There was a statistically significant reduction of all the symptoms in both groups up to the three month follow-up. Regarding dryness and dyspareunia, the relief tent to be more prominent in the ospemifene?+?laser group at all follow-ups and remained statistically significant at three-month follow-up. Specifically, vestibular dryness was significantly lower in the ospemifene?+?laser group compared with the laser treatment group (?87% vs???34%, respectively), and the vestibular health score started declining faster in the ospemifene?+?laser group. Although, additional research is needed to understand the mechanism of action, our data shows that a combination regimen of laser and ospemifene may improve clinical effectiveness for long-term treatment of symptoms associated with the under-recognized genitourinary syndrome of menopause.

目的探讨针刺京骨穴联合推拿治疗背肌筋膜炎的临床疗效。方法将2016年10月—2018年10月收治的背肌筋膜炎患者86例纳入研究,采用随机数字表法分组。对照组43例予以推拿治疗,观察组43例予以针刺京骨穴联合推拿治疗。比较2组患者的治疗总有效率、VAS评分及Oswestry功能障碍指数、痊愈所用时间。结果观察组治疗总有效率为95.3%,而对照组仅为81.4%,差异有统计学意义(P<0.05);2组治疗后VAS评分、Oswestry功能障碍指数均有下降,观察组上述指标低于对照组,差异有统计学意义(P<0.05);观察组痊愈所用时间短于对照组,差异有统计学意义(P<0.05)。结论针刺京骨穴联合推拿治疗背肌筋膜炎的临床疗效突出,可缓解背部疼痛、恢复功能活动,并缩短了愈合时间,提高了生活质量,值得一定的临床推广。     

肠炎清合剂治疗慢性复发型溃疡性结肠炎大肠湿热证的临床观察

外周血miR-150-5p、SOCS1 mRNA对类风湿关节炎“病”“证”诊断意义的初步探讨＊

目的 探讨类风湿关节炎患者外周血miR-150-5p、细胞因子信号抑制因子1（suppressor of cytokine signaling 1，SOCS1）mRNA的表达及对类风湿关节炎（Rheumatoid Arthritis，RA）疾病诊断、中医证型判断的意义。方法 纳入符合诊断标准的RA患者57例及健康对照组19例，根据《22个专业95个病种中医诊疗方案》有关RA的中医证候诊断标准，判断RA的中医证型。qPCR检测RA患者及健康对照组miR-150-5p、SOCS1mRNA的相对表达水平，同时检测血常规、肝功能、肾功能等常规指标。双荧光素酶分析方法判断两者是否存在靶向关系。统计分析miR-150-5p、SOCS1 mRNA对RA疾病的诊断意义及其与中医证型的相关性。结果 RA患者外周血miR-150-5p的相对表达水平下调，低于正常人群（t = -19.019，P < 0.05）；其表达水平随疾病活动度升高，有下降趋势；患者外周血SOCS1 mRNA的相对表达水平上调，低于正常人群（t = 5.333，P < 0.05）；其表达水平随疾病活动度升高，有上升趋势。MiR-150-5p与SOCS1 mRNA有靶向结合关系（P < 0.05）。通过AUC曲线比较，miR-150-5p的相对表达水平区分RA的敏感性及特异性分别为98.1%、92.1%（AUC = 0.972，P < 0.05）；SOCS1 mRNA的相对表达水平无法区分RA（AUC = 0.472，P > 0.05）。RA患者中miR-150-5p的相对表达水平低于3.06，RA患者风湿痹阻证、寒湿痹阻证的相对风险分别为8.33、250.00（P < 0.05）。结论 miR-150-5p、SOCS1 mRNA在RA患者中有差异性表达，且有靶向结合关系。miR-150-5p可能是RA的疾病诊断及中医风湿痹阻证、寒湿痹阻证证型诊断的潜在生物标志物。
