Cystitis as a correlate of female urinary incontinence

The objectives of the research were to study the association between prevalent urge and stress urinary incontinence (UI) and a history of cystitis in adult females. A cross-section of the adult female population, aged 30–59 years, in the Municipality of Aarhus, Denmark, was studied, using self-reported data based on postal questionnaires. The sample consisted of 3114 women, out of whom 2613 (84%) delivered the information requested. The main outcome measures were period prevalence in 1987 of episodes of UI provoked by physical stress and UI associated with a feeling of urge, prevalence of experience of episodes of cystitis and UI related to cystitis in adult life, and prevalence of relative risks, as indicated by odds ratio (OR), of UI conditional on cystitis experience. Results indicated that the 1987 period prevalences of UI provoked by physical stress and UI associated with a feeling of urge were 15% and 9%, respectively. Forty-five per cent reported a history of cystitis and 10% of UI during episodes of cystitis. Both UI provoked by stress and UI associated with a feeling of urge were significantly correlated to cystitis (OR 2.1, P<0.0001, and 1.8, P<0.0001, respectively) and to UI during episodes of cystitis (OR 7.1, P<0.0001, and 5.7, P<0.0001, respectively). When corrected for the stress aspect, UI being associated with a feeling of urge showed no association of its own to a history of cystitis. However, stress and urge aspects were both correlated to the experience of UI during episodes of cystitis. The prevalence of experience of cystitis increased with increasing number of urologic (per operation OR 2.1, P<0.0001) and gynecologic operations (per operation OR 1.5, P<0.0001), e.g. curretage (per operation OR 1.2, P<0.001), but not with the number of abdominal operations or the number of childbirths. It was concluded that cystitis may be an important component of UI etiology. Stress and not urge UI seems to be the key type related to a history of cystitis in general. The experience of UI during cystitis is connected to both stress and urge UI. A history of cystitis may possibly itself by initiated by surgery.     

经阴道无张力吊带术治疗女性压力性尿失禁的体会

目的探讨经阴道无张力吊带术(TVT)治疗女性压力性尿失禁(SUI)的疗效及安全性。方法对2002年5月至2004年12月施行TVT的114例女性SUI患者资料进行回顾性研究。根据Stamey尿失禁分级系统评价TVT手术的有效性。术后较术前尿失禁等级评分改善2级或2级以上为显著改善,1级为改善,无改善甚至加重为无效。术后尿失禁等级为0~1级为完全控尿,2级为有效控尿,3~4级为无效。评估术前、术后的24h尿垫试验及尿动力学检查结果。并对并发症进行统计和分析。结果随访110例(96.5%),随访时间6~30个月。24h尿垫试验术前(38.3±10.4)g,术后(8.8±7.4)g;尿失禁症状评分从术前42.3±11.4,术后20.4±9.2;尿失禁等级评分显著改善者94例(85.5%),改善者12例(10.9%),无效者4例(3.6%)。术后完全控尿者89例(80.9%),有效控尿者14例(12.7%),无效者7例(6.4%)。术中发生膀胱穿孔2例(1.8%),出血14例(12.7%)。术后1个月内有排尿不畅者9例(8.2%),尿频、尿急者12例(10.9%),尿潴留者1例(0.9%);术后6个月后有耻骨上不适者8例(7.3%),排尿不尽者2例(1.8%),尿频、尿急者3例(2.7%)。1例反复尿潴留患者经保守治疗无效,最终将吊带切断。术后未出现吊带处阴道黏膜糜烂和明显盆腔血肿。结论TVT术是目前治疗女性SUI的一种有效、安全的微创手术。     

Reduced peripheral blood mitochondrial DNA content is not a risk factor for Type 2 diabetes.

AIMS: Mitochondrial depletion in pancreatic beta cells is known to reduce glucose stimulated insulin secretion. We aimed to determine whether the offspring of patients with early onset Type 2 diabetes had reduced peripheral blood mitochondrial content relative to control subjects and whether this could lead to a predisposition to type 2 diabetes in later life. METHODS: We measured the levels of mitochondria relative to a single copy genomic target by real time polymerase chain reaction in a series of peripheral blood samples taken from the offspring of Caucasian patients with Type 2 diabetes and matched controls. Measures of insulin sensitivity and beta cell function were also taken. RESULTS: In contrast with previous studies, mitochondrial DNA content was not decreased in the offspring of patients with Type 2 diabetes relative to matched controls in our cohort. Conversely, we noted a small proliferation in mitochondrial numbers in our case subjects. In agreement with these findings, no correlations with either insulin sensitivity or beta cell function were noted. CONCLUSIONS: Our results indicate that reduced mitochondrial DNA content in peripheral blood is not a risk factor for the development of Type 2 diabetes in the offspring of patients with early onset Type 2 diabetes.
