Systemic immune inflammation index in patients with recurrent aphthous stomatitis

ObjectivesRecurrent Aphthous Stomatitis (RAS) a chronic idiopathic oral mucosal disease. But yet the etiology and pathogenesis of RAS are not exactly known, it is thought that inflammation play an important role in the pathogenesis. The aim of this study is to demonstrate the role of systemic inflammation among the possible etiological factors of RAS and to find the possible diagnostic correlation between Systemic Immune Inflammation Index (SII).MethodsPatients who were consulted the otolaryngology outpatient clinic and diagnosed with RAS between 2019–2021 were retrospectively analyzed. Neutrophil/Lymphocyte Ratio (NLR), Platelet/Lymphocyte Ratio (PLR) and SII values were calculated based on the results of complete blood count. Demographic and hematological parameters between control and RAS groups were compared. The statistical significance level was considered as <0.05.ResultsThere was no statistically significant difference between the control and RAS groups in terms of sex and age distributions (p = 0.566 and p = 0.173, respectively). SII, NLR and PLR values were significantly higher in the RAS group compared to the controls (p < 0.001, p < 0.001 and p = 0.001, respectively). A very strong correlation between SII and NLR, moderately strong correlation between SII and PLR and moderate correlation between NLR and PLR values were detected (respectively ρ: 0.813, 0.719, 0.532; p-values <0.001).ConclusionSII, NLR and PLR has significantly higher levels in the RAS group compared to the control group, that it supports the role of systemic inflammation in the etiopathogenesis of RAS. In addition, the results show that SII is a valuable marker for inflammation.Level of evidence4.     

The retrospective study for effectiveness of cervical cerclage in preventing recurrent preterm birth

ObjectiveThis study aimed to clarify the effectiveness of cervical cerclage in preventing recurrent preterm births.Materials and methodsA retrospective study was conducted using the perinatal registration database of the Japan Society of Obstetrics and Gynecology for the Perinatal Center from 2014 to 2016. The efficacies of history-indicated, ultrasound-indicated, and physical examination-indicated cerclage as preventive treatments for women with a history of preterm birth were evaluated by comparing cerclage and non-cerclage cases. Fisher's exact test was performed to evaluate any significant differences in patient backgrounds. Prior to the evaluation, propensity score matching was performed for history-indicated and ultrasound-indicated cerclage patients.ResultsFor this study, 6060 multiparous women with a history of preterm birth were reviewed. After excluding 17 patients with unknown indications for cervical cerclage, 6043 patients were included in the study. History-indicated and ultrasound-indicated cerclage did not reduce the risk of preterm birth in subsequent pregnancies for any of the pregnancy periods (p = 0.413, p = 1.000). In contrast, physical examination-indicated cerclage significantly reduced the risk of subsequent preterm births for all pregnancy periods (p < 0.001).ConclusionSubsequent preterm births were effectively prevented only in physical examination-indicated cerclage cases. For history- or ultrasound-indicated cerclage, statistically significant differences in subsequent preterm births were not evident.     

Fine particulate matter and incidence of metabolic syndrome in non-CVD patients: A nationwide population-based cohort study

Background

It has been reported that particulate matter (PM) is associated with cardiovascular diseases (CVD) while metabolic syndrome is also an important risk factor for CVD. However, few studies have investigated the epidemiological association between PM and metabolic syndrome.

复发性流产患者病因构成分析

背景　复发性流产（RSA）发病率呈逐年上升趋势，严重影响妇女身心健康，目前现代医学对RSA的病因和发病机制尚未完全明确。目的　了解RSA病因的分布情况，以及流产孕周与流产次数和RSA病因之间的关系。方法　选取2018年在新疆医科大学第二附属医院确诊为RSA的患者198例，收集患者的一般资料包括年龄、自然流产次数、流产孕周，并筛查患者的病因：染色体异常、生殖道解剖结构异常、内分泌系统异常、生殖道感染、自身免疫异常等，并对这些资料进行回顾性分析。根据患者的流产孕周，分为早期RSA组（<12周）（155例）和晚期RSA组（≥12周）（43例）；根据流产次数分为2次组（123例）和≥3次组（75例）。分析RSA患者各病因所占比例，以及RSA病因在不同流产孕周组和不同流产次数组间的差异。结果　198例RSA患者，染色体异常9例（4.55%），生殖道解剖结构异常11例（5.56%），内分泌系统异常36例（18.18%），生殖道感染14例（7.07%），自身免疫异常30例（15.15%），不明病因98例（49.49%）。晚期RSA组患者生殖道解剖结构异常发生率大于早期RSA组，不明病因发生率低于早期RSA组（P<0.05）；早期RSA组与晚期RSA组患者染色体异常、内分泌系统异常、生殖道感染、自身免疫异常发生率比较，差异均无统计学意义（P>0.05）。流产次数2次组和流产次数≥3次组患者染色体异常、生殖道解剖结构异常、内分泌系统异常、生殖道感染、自身免疫异常、不明病因发生率比较，差异均无统计学意义（P>0.05）。结论　导致RSA的病因有多种，包括染色体异常、生殖道解剖结构异常、内分泌系统异常、生殖道感染、自身免疫异常及不明病因等多种因素，其中不明病因的RSA占多数；生殖道解剖结构异常对妊娠晚期的影响大于妊娠早期。     

局部复发鼻咽癌的外科挽救治疗CSCD

鼻咽癌放疗后约10%~36%的患者复发。复发病灶通常对放疗不敏感,再程放疗疗效不佳,且会导致严重并发症,而外科治疗可以根治性切除癌灶并避免二次照射,成为复发鼻咽癌理想的挽救治疗方法。鼻外入路挽救手术创伤较大,且均存在不同程度的手术并发症。经鼻内镜鼻咽切除术因微创、切除范围不亚于鼻外入路,逐步成为rT1~2及部分rT3期患者的首选方案,相应的外科分期为复发鼻咽癌的分层治疗提供了科学依据。颈内动脉栓塞术、颅内外血管搭桥术等新技术的运用正在扩大挽救手术适应证,但广泛的外科切除是否优于二程放疗仍需更多实践验证。
