Bacteroides thetaiotaomicron in posthysterectomy infection

We report a patient with clinically significant vaginal posthysterectomy infection due to Bacteroides thetaiotaomicron. The microorganism isolated from the vaginal cuff abscess was beta-lactamase producer and the antibiotic susceptibility pattern showed its resistance to piperacillin-tazobactam and cefoxitin, while the susceptibility to amoxicillin associated with clavulanic acid, metronidazole, and the newer fluoroquinolone moxifloxacin was confirmed.     

Non-closure of peritoneum after abdominal hysterectomy for uterine carcinoma does not increase late intestinal radiation morbidity

Background/AimTo evaluate whether non-closure of the visceral peritoneum after total abdominal hysterectomy (TAH) and bilateral salpingo-oophorectomy (BSO) in patients with uterine corpus carcinoma influences the volume of the small intestine within the irradiated volume during adjuvant radiotherapy or late radiation intestinal toxicity.Materials and methodsA total of 152 patients after TAH + BSO with adjuvant pelvic radiotherapy were studied. The state of peritonealization was retrospectively evaluated based on surgical protocols. The volume of irradiated bowels was calculated by CT-based delineation in a radiotherapy planning system. The influence of visceral peritonealization upon the volume of the small intestine within the irradiated volume and consequent late morbidity was analyzed.ResultsVisceral peritonealization was not performed in 70 (46%) of 152 studied patients. The state of peritonealization did not affect the volume of the irradiated small intestine (p = 0.14). Mean volume of bowels irradiated in patients with peritonealization was 488 cm³ (range 200–840 cm³, median 469 cm³); mean volume of bowels irradiated in patients without peritonealization was 456 cm³ (range 254–869 cm³, median 428 cm³). We did not prove any significant difference between both arms. Nor did we observe any influence of non-peritonealization upon late intestinal morbidity (p = 0.34).ConclusionNon-closure of the visceral peritoneum after hysterectomy for uterine corpus carcinoma does not increase the volume of the small intestine within the irradiated volume, with no consequent intestinal morbidity enhancement.

子宫切除术后患者生活质量的变化及家庭关怀度的影响因素分析

摘要 目的：探讨子宫切除术后患者生活质量的变化及家庭关怀度的影响因素。方法：选取2017年1月~2020年1月期间在我院行子宫切除术的158例患者为研究对象,采用生活质量评价量表（SF-36）、家庭关怀度指数问卷（APGAR）对子宫切除术后患者的生活质量、家庭关怀度进行评估。根据患者的APGAR评分分为家庭功能良好组（123例）和家庭功能障碍组（35例）,采用多因素Logistic回归分析子宫切除术后患者家庭关怀度的影响因素。结果：158例子宫切除术后患者的SF-36中得分最高的维度为生理功能（PF）（88.97±9.28）分,最低为心理健康（MH）（62.39±7.93）分,而术前评分中最高为PF（90.89±8.97）分,最低为MH（74.83±8.87）分,术后患者的MH评分有显著下降（P<0.05）。158例患者APGAR总得分为（7.37±2.32）分,其中家庭功能良好（7~10分）患者123例、中度障碍（4~6分）28例、重度障碍（0~3分）7例。经单因素分析显示：两组患者年龄、手术切除方式、原发疾病类型、居住地、文化程度对比无统计学差异（P>0.05）,而两组在切除时长、家庭年收入、婚姻状况、家庭关系方面对比有统计学差异（P<0.05）。经多因素Logistic回归分析显示：切除时长、婚姻状况、家庭关系及家庭年收入均是子宫切除术后患者家庭关怀度的影响因素。结论：子宫切除术后患者生活质量及家庭关怀度均处于中等水平。其家庭关怀度受多种因素的影响,临床中应结合患者实际情况和其可能存在的相关因素进行适当干预,以减少家庭功能障碍的发生风险。     

不同术式对雌兔内分泌和骨代谢的影响

目的观察不同子宫、卵巢切除术式对兔术后早期内分泌激素和骨代谢的影响。方法45只健康成年雌兔随机分为5组,Ⅰ组：单纯子宫全切除组;Ⅱ组：子宫全切＋单侧卵巢切除组;Ⅲ组：子宫全切＋双侧卵巢切除组;Ⅳ组：双侧卵巢切除组;Ⅴ组：对照组。测量术前、术后1、2、3个月的体重、雌二醇（E2）、甲状旁腺素（PTH）、血钙、血清碱性磷酸酶（ALK）和骨密度（BD）。结果术后第2、3个月,Ⅲ组、Ⅳ组出现烦躁不安和体重减轻的实验兔要显著高于Ⅰ组和Ⅱ组;术后第2个月,Ⅱ组E2浓度（17．66±6．06）pg／mL,显著降低,术后第3个月,血钙增高（3．86±0．11）mmol／L,第2椎骨骨密度显著降低,与对照组相比（P〈0．05）,有显著差异;Ⅱ组术后第3个月PTH增高,但与对照组相比无显著差异（P〉0．05）。Ⅲ组、Ⅳ组术后第2个月起,E2、PTH、血钙、ALT和BD,与对照组相比均有显著改变。结论子宫切除术会影响雌兔内分泌的变化,只保留单侧卵巢时不能维持相应的正常生理功能。     

Hysterectomy and risk of epithelial ovarian cancer by histologic type,endometriosis, and menopausal hormone therapy

BackgroundThis nationwide, register-based case-control study investigated the association between hysterectomy and risk of epithelial ovarian cancer according to histology and by history of endometriosis and menopausal hormone therapy (MHT) use.MethodsFrom the Danish Cancer Registry, all women registered with epithelial ovarian cancer at age 40–79 years during 1998–2016 were identified (n = 6738). Each case was sex- and age-matched to 15 population controls using risk-set sampling. Information on previous hysterectomy on benign indication and potential confounders was retrieved from nationwide registers. Conditional logistic regression was used to calculate odds ratios (ORs) with 95% confidence intervals (CIs) for the association between hysterectomy and ovarian cancer according to histology, endometriosis, and use of MHT.ResultsHysterectomy was not associated with risk of epithelial ovarian cancer overall (OR=0.99; 95% CI 0.91 –1.09) but was associated with reduced risk of clear cell ovarian cancer (OR=0.46; 95% CI 0.28–0.78). In stratified analyses, decreased ORs associated with hysterectomy were seen in women with endometriosis (OR=0.74; 95% CI 0.50–1.10) and in non-users of MHT (OR=0.87; 95% CI 0.76–1.01). In contrast, among long-term MHT users, hysterectomy was associated with increased odds for ovarian cancer (OR=1.20; 95% CI 1.03–1.39).ConclusionHysterectomy was not associated with epithelial ovarian cancer overall but with reduced risk of clear cell ovarian cancer. Our findings may suggest a reduced risk of ovarian cancer after hysterectomy in women with endometriosis and in MHT non-users. Interestingly our data pointed to an increased ovarian cancer risk associated with hysterectomy among long-term users of MHT.     

Declining hysterectomy prevalence and the estimated impact on uterine cancer incidence in Scotland

AimThe prevalence of hysterectomy is decreasing worldwide. It is not clear whether changes in the population at risk (women with intact uteruses) have contributed to an increased uterine cancer incidence. This study aims to assess the effect of changing trends in hysterectomy prevalence on uterine cancer incidence in Scotland.MethodsThe population of women aged ≥25 years with intact uteri was estimated using the estimated hysterectomy prevalence in 1995 and the number of procedures performed in Scotland (1996–2015). Age-standardized uterine cancer incidence was estimated using uncorrected (total) or corrected (adjusted for hysterectomy prevalence) populations as denominators and the number of incident cancers as numerators. Annual percentage change in uterine cancer was estimated.ResultsHysterectomy prevalence fell from 13% to 10% between 1996–2000 and 2011–2015, with the most marked decline (from 20% to 6%) in the 50–54-year age group. After correction for hysterectomy prevalence, age-standardized incidence of uterine cancer increased by 20–22%. Annual percentage change in incidence of uterine cancer remained stable through the study period and was 2.2% (95%CI 1.8–2.7) and 2.1% (95%CI 1.7–2.6) for uncorrected and corrected estimates, respectively.ConclusionUterine cancer incidence in Scotland corrected for hysterectomy prevalence is higher than estimates using a total female population as denominator. The annual percentage increase in uterine cancer incidence was stable in both uncorrected and corrected populations despite a declining hysterectomy prevalence. The rise in uterine cancer incidence may thus be driven by other factors, including an ageing population, changing reproductive choices, and obesity.     

宫颈癌患者行根治性子宫切除术且保留盆腔自主神经的效果观察

目的:探讨宫颈癌患者行保留盆腔自主神经的根治性子宫切除术的临床效果。方法:按照随机数字表法将入选的48例宫颈癌患者随机分为对照组和试验组两组,每组患者各24例,其中对照组患者均采用传统的宫颈癌根治手术治疗,而试验组患者则采用保留盆腔自主神经的根治性子宫切除术进行治疗,比较两组患者的术中情况和术后恢复情况等。结果:两组患者的子宫切除出血量和术中总出血量以及术中输血率均无明显差异(均P0.05),但是试验组患者的子宫切除时间和手术总时间显著长于对照组患者(t=2.934,P0.05;t=3.121,P0.05)。两组患者之间的术后排气、排便时间均无明显差异(均P0.05),提示两组患者术后直肠功能无明显差异;对照组患者的术后残余尿量100ml时间与术后残余尿量50ml时间均显著高于试验组患者(t=2.891,P0.05;t=3.092,P0.05)。术后试验组患者的首次排尿感和急迫排尿感以及最大腹压等均显著低于对照组患者(t=4.283,P0.05;t=4.027,P0.05;t=3.137,P0.05);而最大膀胱压和最大尿流量以及最大逼尿肌压等则显著高于对照组(t=3.192,P0.05;t=2.938,P0.05;t=3.572,P0.05)。结论:采取保留盆腔自主神经的根治性子宫切除术能够较好地减少宫颈癌患者临床并发症的出现,具有较好的治疗效果,值得加以推广和运用。     

胎盘多肽对子宫肌瘤患者T 淋巴细胞亚群、NK细胞及炎症因子水平的影响

目的:探讨胎盘多肽对子宫肿瘤切除术后患者血清炎症因子变化和免疫功能的影响。方法:收集我院收治的子宫肿瘤切除术后患者57例,根据就诊先后顺序不同分为对照组和实验组,实验组采用胎盘多肽治疗,对照组采用常规治疗。检测两组患者CD3~+、CD4~+、CD8~+、NK细胞、CRP及IL-6水平,并比较两组的临床效果。结果:治疗后,两组患者血清CRP及IL-6水平均低于治疗前,且实验组明显低于对照组,差异具有统计学意义(P0.05)。治疗后,两组患者CD3~+、CD4~+、CD4~+/CD8~+、NK细胞均高于治疗前,而CD8~+低于治疗前,差异具有统计学意义(P0.05);实验组患者治疗后CD3~+、CD4~+、CD4~+/CD8~+、NK细胞显著高于对照组,而CD8~+低于对照组,差异具有统计学意义(P0.05)。与对照组相比,实验组患者的首次排气和排便时间明显较短,差异具有统计学意义(P0.05)。结论:胎盘多肽能够明显改善子宫肌瘤切除患者的免疫功能,降低炎症反应,有助于患者术后康复。
