Detection of high-grade cervical disease among women referred directly to colposcopy after a positive HPV screening test varies with age and cytology findings

Australia's new HPV-based cervical screening program is based on an algorithm that incorporates reflex cytology to guide decisions about further follow-up with colposcopy and, if indicated, biopsy. We reviewed results for 2300 women referred directly for colposcopy after their first positive HPV screening test, to determine the proportion that had underlying histological high-grade abnormality (HGA). Overall, HGA was detected in 24.3% of women. Among HPV16/18 positive women, 18.0% had HGA, increasing from 6.6% among women with negative cytology to 79.7% among women with high-grade squamous lesion or worse, or any glandular lesion on cytology (HSIL+; P-trend < .001). For this latter group, the proportion with HGA was higher among HPV16/18 positive women than among those positive for other oncogenic types (68.8%; P = .029). Among women with ASC-H cytology, 51.8% had HGA, with no difference between HPV groups (P = .314). In analyses by age-groups, detection of HGA was highest, at 36.4%, among women younger than 35 years, then decreased significantly to 5.9%, among women aged 65 to 74 years (P-trend < .001). The relationship of decreasing HGA detection with increasing age was strong for women with negative cytology, and those with ASC-H cytology (P-trend < .001 for each). For women with HSIL+ cytology, detection of HGA was high and stable, regardless of age (P-trend = .211). This report describes the first follow-up colposcopy findings in Australia's new HPV-based cervical screening program. The results demonstrate the additional value of reflex cytology in managing HPV positive women and suggest that further refinement of the risk-based algorithm to account for age may be warranted.     

SU11274抑制人子宫内膜癌细胞增殖的分子机制

目的:探索HGF/c-met传导通路抑制剂SU11274抑制子宫内膜癌细胞增殖的分子机制。方法:使用不同浓度SU11274（0.5 μmol/L、1.0 μmol/L、1.5 μmol/L）作用ishikawa 和HEC-1B 两种细胞株1小时后，加入40 ng/ml的HGF，继续培养48小时，然后使用RT-PCR检测c-met、Survivin、XIAP水平以及Western blot检测细胞中Survivin、XIAP蛋白表达水平。结果:ishikawa细胞c-met低表达，而HEC-1B细胞c-met明显高表达，HEC-1B细胞中c-met mRNA表达量为ishikawa中的2.5倍。SU11274可以使HEC-1B、ishikawa细胞的Survivin、XIAP蛋白表达下调，呈现剂量依赖性，并且在HEC-1B细胞中，该下调作用明显强于ishikawa细胞（P<0.05）。结论:SU11274可以通过下调HGF/c-met传导通路中Survivin、XIAP的表达来抑制人子宫内膜癌细胞增殖。     

Human papillomavirus and urinary bladder cancer revisited

This review aims to present data on the association between human papillomavirus (HPV) and urinary bladder cancer (BC), especially of the subtype squamous cell carcinoma (SCC). Furthermore, the current data on the relation between p16, HPV, and BC are reviewed. PubMed was searched for ‘Humans’ [MESH] AND ‘Papillomaviridae’ [MESH] AND ‘Urinary Bladder Neoplasms’ [MESH], resulting in 157 potential articles. After profound reviewing, 18 articles were included in this review. Only original articles in English were included. A variable number of HPV genotypes in a small number of cases have been investigated in several studies with various methodology. HPV was present in 0–100% of cases depending on inclusion and exclusion criteria. SCC studies are mostly hampered by low number of cases whereas the few studies with a high number show a slightly higher prevalence of different HPV genotypes compared to pure urothelial carcinoma. Studies on p16 status in HPV positive cases are even more scarcely reported and show conflicting results. Most studies fail to prove clear-cut relevance of HPV in BC irrespectively of histological subtype. Negative p16 staining cannot rule out positive HPV status.     

The contribution of HERV-E clone 4-1 and other HERV-E members to the pathogenesis of rheumatic autoimmune diseases

Human endogenous retroviruses (HERV)-E consist of a family of more than 1300 elements, stably integrated in the human genome. Some of them are full-length proviruses able to synthesize the viral proteins gag, pol and env. The reactivation of HERV-E elements has been associated to placentation, cancer and autoimmunity. In this narrative review, we aimed to report the status of the art concerning the involvement of HERV-E in rheumatic autoimmune diseases. Following a research on PubMed database, a total of 87 articles were selected. The highest amount of evidence derives from studies on systemic lupus erythematosus (SLE), whereas a few to no data are available on other immune-mediated diseases. In SLE, the hyper-expression of HERV-E clone 4-1 in peripheral blood mononuclear cells or differentiated lymphocytes has been associated with disease activity and autoantibody production. It is likely that HERV-E take part to the pathogenesis of rheumatic autoimmune diseases but additional research is needed.

目的探讨派特灵与奥平栓用于宫颈高危型、低危型人乳头瘤病毒(HPV)感染中的疗效及对免疫功能的影响。方法选取于无锡市第五人民医院就诊的HPV感染患者,根据HPV检测结果,分别按照随机数字表法分为高危型的观察组和对照组各54例和低危型的观察组和对照组各30例。对照组予奥平栓治疗,观察组在对照组基础上联合使用派特灵,对比患者HPV病毒载量、治疗有效率、免疫因子表达水平及不良反应发生情况。结果经治疗,各组HPV病毒载量水平均较治疗前明显下降(P<0.05),且高危型和低危型观察组的HPV病毒载量均明显低于对照组,差异均有统计学意义(P<0.05);高危型与低危型观察组患者治疗有效率普遍高于对照组,差异均有统计学意义(χ^2=2.170,P=0.030;χ^2=2.160,P=0.031);经治疗,各组Th17、Treg、骨髓来源的抑制性细胞(MDSC)水平均较治疗前明显下降(P<0.05),且高危型与低危型观察组Th17、Treg、MDSC水平均明显低于对照组,差异均有统计学意义(P<0.05);高危型与低危型观察组患者不良反应总发生率普遍低于对照组,差异均有统计学意义(χ^2=2.110,P=0.035;χ^2=2.050,P=0.040)。结论派特灵与奥平栓可提高宫颈高危型、低危型HPV感染患者治疗效果,提高免疫功能。     

Definición de continencia y factores pronósticos para la recuperación temprana de la continencia urinaria en la prostatectomía radical robótica con reconstrucción posterior del rabdoesfínter. Análisis post hoc de un ensayo clínico aleatorizado

IntroductionUrinary incontinence after radical prostatectomy (RP) is an adverse event with high impact on patient's quality of life. Nowadays there is no standardized method for urinary continence measurement. Posterior rhabdosphincter reconstruction (PRR) is a surgical step that can improve early urinary continence after RP. Our objective was to analyse different continence definitions and predictors of urinary continence recovery after robot-assisted RP (RARP).Materials and methodsWe conducted a double-blind, randomised controlled trial (NCT03302169) including 152 consecutive patients with localized prostate cancer subjected to RARP. Patients were randomised to single urethrovesical anastomosis (control arm) or PRR before urethrovesical anastomosis (PRR arm). Urinary continence was measured with the EPIC-26 and ICIQ-SF validated questionnaires, and pad use (0-1 pads and no pads), at 7, 15, 30, 90, 180 and 365 days after catheter removal. Prognostic factors for early urinary continence recovery were analysed.Results72 patients were included in the control arm and 80 in the PRR arm. Baseline characteristics were similar between arms, except body mass index, which was higher in PRR arm. “No pad” was the only definition assessing the benefit of PRR at 30 days, 33.8% in PRR arm and 18.1% in control arm, p = 0.022; and at 90 days, 58.8 and 43.1% respectively, p = 0.038. Questionnaires did not detect differences in terms of continence recovery. PRR was the only predictor for early continence recovery, p = 0.03.ConclusionsPRR increased early urinary continence recovery after RARP. Continence definition was critical to assess benefit. The only predictive factor for early continence recovery was PRR.     

Aortitis and periaortitis: The puzzling spectrum of inflammatory aortic diseases

Aortitis and periaortitis are inflammatory diseases of the aorta and its main branches; they differ in the extension of inflammation, which is confined to the aortic wall in aortitis, and spreads to the periaortic space in periaortitis. Aortitis is classified as non-infectious or infectious. Non-infectious aortitis represents a common feature of large-vessel vasculitides but can also be isolated or associated with other rheumatologic conditions. Periaortitis can be idiopathic or secondary to a wide array of etiologies such as drugs, infections, malignancies, and other proliferative diseases. Notably, both aortitis and periaortitis may arise in the context of IgG4-related disease, a recently characterised fibro-inflammatory systemic disease. Prompt recognition, correct diagnosis and appropriate treatment are essential in order to avoid life-threatening complications.
