Different cervical cancer screening approaches in a Chinese multicentre study
To evaluate alternative cervical cancer screening methods, digital colposcopy and collection of cervical exfoliated cells for liquid-based cytology (LBC) and hybrid capture 2 (HC2) testing were performed among 2562 women aged 15–59 years in three study sites in the People's Republic of China (rural Shanxi province, Shenyang city in Liaoning province and Shenzhen city in Guangdong province). Visual inspection with acetic acid (VIA) was also evaluated independently from colposcopy. A total of 74 cases of histologically confirmed cervical intraepithelial neoplasia grade 2 or worse (CIN2+) were identified, and 16 CIN2+ cases were imputed among unbiopsied women to correct for verification bias. Corrected sensitivity for CIN2+ was 37% for VIA, 54% for colposcopy, 87% for LBC with a threshold of atypical cells of undetermined significance (LBC⩾ASCUS), 90% for HC2, 84% for LBC using HC2 to triage ASCUS and 96% for positivity to LBC⩾ASCUS or HC2. For VIA, sensitivity was much lower among women ⩾40 years (12%) than those aged ⩽39 years (50%). Specificity varied from 77% for positivity to LBC⩾ASCUS or HC2, up to 94% for LBC using HC2 to triage ASCUS. In conclusion, LBC, HC2 and their combinations performed well, whereas VIA missed a majority of CIN2+, particularly in older women. Digital colposcopy performed better than VIA, but still missed nearly half of CIN2+ in this study
Lifestyle and socio-demographic factors associated with high-risk HPV infection in UK women
The world age-standardised prevalence of high-risk HPV (hrHPV) infection among 5038 UK women aged 20–59 years, with a low-grade smear during 1999–2002, assessed for eligibility for TOMBOLA (Trial Of Management of Borderline and Other Low-grade Abnormal smears) was 34.2%. High-risk HPV prevalence decreased with increasing age, from 61% at ages 20–24 years to 14–15% in those over 50 years. The age-standardised prevalence was 15.1, 30.7 and 52.7%, respectively, in women with a current normal, borderline nuclear abnormalities (BNA) and mild smear. In overall multivariate analyses, tertiary education, previous pregnancy and childbirth were associated with reduced hrHPV infection risk. Risk of infection was increased in non-white women, women not married/cohabiting, hormonal contraceptives users and current smokers. In stratified analyses, current smear status and age remained associated with hrHPV infection. Data of this type are relevant to the debate on human papillomavirus (HPV) testing in screening and development of HPV vaccination programmes
Immediate Breast Reconstruction with a Latissimus Dorsi Flap Has No Detrimental Effects on Shoulder Motion or Postsurgical Complications up to 1 Year after Surgery
Coordenação de Aperfeiçoamento de Pessoal de NÃvel Superior (CAPES)Background: Mastectomy negatively affects scapulothoracic and glenohumeral kinematics. Breast reconstructive methods such as the latissimus dorsi flap can result in anatomical modifications that may in theory further affect the shoulder apparatus. The purpose of this study was to examine the effects of latissimus dorsi flap reconstruction on the recovery of shoulder motion and other postsurgical problems during the first year after mastectomy. Methods: This was a prospective cohort study of 104 consecutive mastectomies (47 with immediate latissimus dorsi flaps). Shoulder range of motion was assessed before and at 1, 3, 6, and 12 months after surgery. Pain, tissue adhesion, scar enlargement, and web syndrome were assessed during follow-up. Results: There was a 30 percent decrease of shoulder range of motion 1 month after surgery, with gradual recovery over time. However, mean abduction and flexion capacities did not reach baseline levels and were on average 5 to 10 percent lower than baseline, even after 1 year. Over time, the latissimus dorsi flap was not associated with restriction of flexion or abduction. Scar enlargement (at the first month, p = 0.009) and tissue adhesion (at month 12, p = 0.032) were significantly less common in the latissimus dorsi flap group. Conclusions: The authors' study clearly suggests that the additional anatomical manipulation required for the latissimus dorsi flap procedure does not further affect shoulder kinematics and is associated with a lower incidence of tissue adhesion.1315673E680ECoordenação de Aperfeiçoamento de Pessoal de NÃvel Superior (CAPES)Coordenacao de Aperfeicoamento de Pessoal de Ensino Superior, BrazilCoordenação de Aperfeiçoamento de Pessoal de NÃvel Superior (CAPES
Immediate Breast Reconstruction With Transverse Latissimus Dorsi Flap Does Not Affect the Short-term Recovery of Shoulder Range of Motion After Mastectomy
Immediate breast reconstruction, depending on the surgical strategy, can result in anatomic modifications that may affect the shoulder apparatus. This study compares the recovery of shoulder range of motion (ROM), after mastectomy, in women with and without immediate breast reconstruction with latssimus dorsi flap (LDF). This was a prospective study with 87 women who underwent mastectomy (41 with LDF). Shoulder ROM was assessed with goniometry, with a universal full-circle manual goniometer, prior to surgery, and on a weekly basis during the first 4 weeks postoperatively. Reconstruction with LDF was not associated with a decrease in shoulder ROM (P = 0.84). By the end of the 4-week assessment program, women in both groups still had an average reduction of 30 degrees in their shoulder ROM compared with baseline. Factors significantly associated with a reduction in shoulder ROM during the recovery period were complete dissection of the axilla, current smoking behavior, and presence of painful axillary cords. It is likely that breast reconstruction with LDF has little or no effect on shoulder ROM in the immediate postoperative period. It is also possible that LDF effects (if any) are overridden by the major reduction (over 30% in the immediate postoperative period, subsiding partially during the first weeks postoperatively) in shoulder ROM caused by mastectomy.64440240
Performance of Pap smear and human papilloma virus testing in the follow-up of women with cervical intraepithelial neoplasia grade 1 managed conservatively
Background. Conservative management (follow-up) of cervical intraepithelial neoplasia grade 1 (CIN1) is acceptable, but evidence on performance of follow-up tools, such as Pap smear and human papilloma virus (HPV) test, is still needed. Methods. A cohort of 78 women with histologically confirmed CIN1, referred because of atypical squamous cell or low-grade squamous intraepithelial lesion in their Pap smear, was enrolled between August 2000 and September 2002 and was prospectively followed-up at 6 and 12 months, until September 2003. Follow-up examinations included Pap test and Hybrid Capture II (HCII) with high-risk HPV, colposcopy, and cervical biopsies in patients with persistent abnormalities. Odds ratios and performance indicators (with 95% confidence interval) were calculated for HPV and Pap test results in detecting biopsy-confirmed CIN during the follow-up. Results. Thirty-seven (47%) of the women were HPV-positive at baseline. At first follow-up visit, 30 women had persistent CIN1 and one woman progressed to CIN2; 15 patients had CIN1 and one patient CIN2 at the second follow-up visit. Women with persistent CIN1 (or progression) during follow-up had a significantly higher HPV detection rate and abnormal Pap tests, compared to women with regressive disease. Cytology had a far better sensitivity in detecting CIN than HCII at the first follow-up visit (81 versus 52%, respectively), whereas both examinations had equivalent sensitivities at the second follow-up visit (69 and 56%, respectively). Cytology had a superior negative predictive value at the first follow-up visit and better positive predictive value, in addition, at the second visit. Conclusions. Because cytological abnormalities correlated generally better with the persistence of biopsy-confirmed CIN1 in this follow-up protocol, HCII test is the second-hand option to Pap test, but the use of both Pap and HCII together seems an unnecessary waste of resources.85444445
