Background. Excisional treatment of preinvasive cervical dysplasia has been associated with adverse pregnancy outcomes. We aimed to examine trends in the rate of excisional treatment in reproductive age women in the era of HPV vaccination.Methods. National data for Australia regarding histological diagnoses of cervical dysplasia and excisional treatment for the period from 2004 to 2013 inclusive were obtained from two datasets and used to calculate age-stratified incidence rates of excisional treatment and of excisional treatments per diagnosis of dysplasia.Results.The incidence of low-grade squamous dysplasia fell in all age groups, while the incidence of high-grade dysplasia fell in the 20-to-24-year group but rose slightly for older age groups. The rate of excisional treatment fell in women aged under 35 but there was no significant change for women 35 years or older. The rate of all excisional treatments (loop excision + cone biopsy) per high-grade diagnosis (CIN2 + CIN3 + adenocarcinomain situ) fell across all three age-bands in both datasets.Conclusion. To ensure that the use of excisional treatment is appropriate, with lower rates for younger HPV-vaccinated women, close surveillance, audit, and ongoing education will be required.

Abstract Background Increasing evidence suggests that 1-dose human papillomavirus (HPV) vaccination may protect significantly against HPV-related disease. We provide nationwide, real-world data on the risk of genital warts (GWs) after <3 vaccine doses. Methods All Danish women born in 1985–2003 were identified, and individual-level vaccination data were retrieved. The cohort was followed up for first occurrence of GWs until 31 December 2016. Using Poisson regression, we calculated incidence rates (IRs) of GWs per 100 000 person-years and IR ratios (IRRs) with corresponding 95% confidence intervals (CIs) for GWs, according to vaccination status, age at first dose, and calendar time. Results The cohort comprised 1 076 945 girls and women, of whom 485 408 were vaccinated. For girls initiating vaccination at age 12–14 years and 15–16 years, 1-dose vaccine effectiveness (VE) was 71% (IRR = 0.29; 95% CI, .22–.38) and 62% (0.38; .29–.49), respectively, compared with unvaccinated girls. In the same age groups, 2-dose VE was 78% (IRR, 0.22; 95% CI, .18–.26) and 68% (0.32; .26–.38), respectively. After 2009, the IRRs for 3 versus 1 dose and 2 versus 1 dose increased towards unity over calendar time, being 0.69 (95% CI, .57–.84) and 0.86 (.68–1.08) in 2016, respectively. Conclusions In this study, 1 or 2 doses of quadrivalent HPV vaccine was associated with substantial protection against GWs in girls vaccinated at age ≤16 years. The 1-dose VE approached that of 3 or 2 doses over calendar time, probably reflecting the impact of herd protection.

Background: Clinicians commonly perform colposcopy directed biopsies on patients with low grade squamous intraepithelial lesion (LSIL) on PAP cytology even when not consistent with clinical guidelines. Objective: We study the association of PAP cytology screening results with cervical intra-epithelia neoplasia (CIN) 2-3 high-grade dysplasia, as confirmed by colposcopy-directed biopsy. Methods: A retrospective study of 263 women with an abnormality on the PAP smear. Multinomial logistic regression was performed with predictors of PAP cytology screening results with the outcome variable of colposcopy-directed biopsy. Results: High grade squamous intraepithelial lesion (HSIL) had significantly increased relative risk for CIN 2-3 (RR: 9.85, 95% CI: 1.84, 52.79, p=0.008). LSIL was not significantly associated with CIN 2-3. In the comparisons of negative with CIN-1, both HSIL and LSIL were not significantly associated with a negative biopsy. Conclusion: HSIL is associated with cervical dysplasia of CIN 2-3 while LSIL is not associated with cervical dysplasia of CIN 2-3. We do not recommend routine biopsies in patients with LSIL cytologic abnormalities unless additional compelling factors exist.

Abstract Background Household surveys remain important sources of stillbirth data, but omission and misclassification are common. Classifying adverse pregnancy outcomes as stillbirths requires accurate reporting of vital status at birth and gestational age or birthweight for every pregnancy. Further categorisation, e.g. by sex, or timing (intrapartum/antepartum) improves data to understand and prevent stillbirth. Methods We undertook a cross-sectional population-based survey of women of reproductive age in five health and demographic surveillance system sites in Bangladesh, Ethiopia, Ghana, Guinea-Bissau and Uganda (2017–2018). All women answered a full birth history with pregnancy loss questions (FBH+) or a full pregnancy history (FPH). A sub-sample across both groups were asked additional stillbirth questions. Questions were evaluated using descriptive measures. Using an interpretative paradigm and phenomenology methodology, focus group discussions with women exploring barriers to reporting birthweight for stillbirths were conducted. Thematic analysis was guided by an a priori codebook. Results Overall 69,176 women reported 98,483 livebirths (FBH+) and 102,873 pregnancies (FPH). Additional questions were asked for 1453 stillbirths, 1528 neonatal deaths and 12,620 surviving children born in the 5 years prior to the survey. Completeness was high (> 99%) for existing FBH+/FPH questions on signs of life at birth and gestational age (months). Discordant responses in signs of life at birth between different questions were common; nearly one-quarter classified as stillbirths on FBH+/FPH were reported born alive on additional questions. Availability of information on gestational age (weeks) (58.1%) and birthweight (13.2%) was low amongst stillbirths, and heaping was common. Most women (93.9%) were able to report the sex of their stillborn baby. Response completeness for stillbirth timing (18.3–95.1%) and estimated proportion intrapartum (15.6–90.0%) varied by question and site. Congenital malformations were reported in 3.1% stillbirths. Perceived value in weighing a stillborn baby varied and barriers to weighing at birth a nd knowing birthweight were common. Conclusions Improving stillbirth data in surveys will require investment in improving the measurement of vital status, gestational age and birthweight by healthcare providers, communication of these with women, and overcoming reporting barriers. Given the large burden and effect on families, improved data must be made available to end preventable stillbirths.

Introduction: Our previous studies showed elevated levels of Semaphorin3a (Sema3A) in the urine of patients with urothelial cancer compared to healthy patients. The aim of this study was to analyze the extent of Sema3A expression in normal and malignant urothelial tissue using immune-staining microscopic and morphometric analysis. Materials and Methods: Fifty-seven paraffin-embedded bladder samples were retrieved from our pathology archive and analyzed: 14 samples of normal urothelium, 21 samples containing low-grade urothelial carcinoma, 13 samples of patients with high-grade urothelial carcinoma, 7 samples containing muscle invasive urothelial carcinoma, and 2 samples with pure urothelial carcinoma in situ. All samples were immunostained with anti Sema3A antibodies. The area of tissue stained with Sema3A and its intensity were analyzed using computerized morphometry and compared between the samples’ groups. Results: In normal bladder tissue, very light Sema3A staining was demonstrated on the mucosal basal layer and completely disappeared on the apical layer. In low-grade tumor samples, cells in the basal layer of the mucosa were also lightly stained with Sema3A, but Seama3A expression intensified upon moving apically, reaching its highest level on apical cells exfoliating to the urine. In high grade urothelial tumors, Seama3A staining was intense in the entire thickness of the mucosa. In samples containing carcinoma in situ, staining intensity was high and homogenous in all the neoplastic cells. Conclusions: Sema3A may be serve as a potential non-invasive marker of urothelial cancer.

Abstract Background Persistent infection by high-risk Human Papillomavirus (hrHPV) are the major cause of cervical cancer. Studies report disparities in the incidence of infection and the various genotypes of this virus in different age groups, suggesting a higher frequency of hrHPV in young women and low-risk subtypes being predominant in older women. This study aimed to investigate the incidence and distribution of hrHPV genotypes in postmenopausal women as well as the correlation with the cytological findings. Methods 16 859 women, aged 50–64 years, performed cervical cancer screening test in Friuri Venezia Giulia region, Italy. The infection was evaluated by the Polymerase Chain Reaction methodology and the positive samples were evaluated by Liquid Based Cytology according to the Bethesda System from 2014. A statistical analysis was performed to study the molecular and cytological data of this population. Results hrHPV infection were found in 5.8% of the women and 78.3% of these were caused by hrHPV other than HPV16 and HPV18 (). Also, 65.7% of the positive samples were negative for intraepithelial lesion or malignancy while low grade squamous intraepithelial lesion was the most frequent (22.4%). There was an increase in the number of high-grade intraepithelial lesions in the presence of HPV16 compared to that recorded when this genotype was absent (20.8% vs. 8.5%). No cervical cancers were detected. Conclusions Infection with hrHPV is uncommon in postmenopausal women and it is mostly caused by subtypes less associated with the development of cervical cancer. Yet, HPV16 infection triggers the development of high-grade lesions.

Abstract BACKGROUND Congenital (<3 months) and infant (3 to 11 months) brain tumors are biologically different from tumors in older children, but epidemiology of these tumors has not been studied comprehensively. Insight into epidemiological differences could help tailor treatment recommendations by age and increase overall survival (OS). METHODS Population-based data from the SEER 18 registries was obtained for 14,493 0-19-year-olds diagnosed with CNS tumors between 1990 and 2015. Incidence, treatment, and survival were analyzed using Chi-square and Kaplan-Meier analyses. RESULTS Between the <3 month, 3–5 month, 6–11 month, and 1–19 year age groups, tumor type distribution differed significantly (p<0.001); high-grade glioma (HGG) was most common in the <3-month-olds, while low-grade glioma (LGG) was most common in the other groups. 5-year OS for all tumors was 36.7% (<3 months), 56.0% (<3–5 months), 63.8% (6–11 months), and 74.7% (1–19 years) (log rank p<0.001). OS by tumor type was worst for <3-month-olds with LGG, medulloblastoma, and other embryonal tumors; OS was worst for 3-5-month-olds with ependymoma, <1-year-olds collectively with atypical teratoid-rhabdoid tumor, and 1-19-year-olds with HGG (log rank p<0.02 for all tumor types). <3-month-olds were least likely to receive any treatment for each tumor type and least likely to undergo surgery for all except HGG. <1-year-olds were far less likely than 1-19-year-olds to undergo radiation for embryonal tumors, as expected, but were also less likely to undergo chemotherapy. CONCLUSIONS Congenital/infant CNS tumors differ pathologically, therapeutically, and prognostically from those in older children. Treatment changes could help address poorer outcomes for these young patients.

The study has been done on 36 samples of biopsies which drawn from patients suffered from ulcerative colitis, the samples were taken from female & male of different ages. The goal was to observe the gene expression of the suppresser tumor gene P53, & the suppresser apoptosis gene Bcl-2, by using in situ hybridization technique. The results showed that there were relationships between both genes (P53 & Bcl-2) in patients suffered from ulcerative colitis compared with healthy individuals. The suppresser gene P53 gave 63% in the high grade(3) , 29 % in the intermediate stage (2) & 8% in the low grade (1) .While for the suppresser apoptosis gene Bcl-2 , the results showed increasing in the activity of this gene , which gave 66% in the high grade(3) , 27% in the intermediate stage (2) , & 7% in the low grade (1) . These results indicate accumulated mutations in the gene P53 & increase in the activity of gene Bcl-2 in inflamed colonic tissue of chronic ulcerative colitis. This gave an indication of early detection for diagnostic, therapeutic and monitoring purposes.

Abstract Between 1935 and 1974, 3598 episodes of head trauma among Olmsted County, Minnesota, residents resulted in 1097 skull fractures. Of these, 53% were simple, 16% were depressed, 12% were compound, and 19% were basilar. The age- and sex-adjusted incidence of skull fractures was 44.3 per 100,000 person-years overall, was somewhat greater in the urban than in the rural areas of Olmsted County, and was relatively stable for the final 30 years of the study. Age-specific incidence rates were highest for the very young, and simple linear fractures were the predominant type of skull fracture in this age group and among the elderly. The male:female ratio of incidence rates varied from 2.1:1 to 4.5:1 depending on fracture type. Motor vehicle accidents accounted for 38% of the skull fractures and were a particularly important cause among young males. Falls accounted for 37% of the skull fractures and were the major cause of fractures in the elderly and pediatric age groups. The results of this population-based study may be helpful in formulating recommendations for the evaluation and management of head-injured patients.

Purpose: The question of overtreatment of ductal carcinoma in situ (DCIS) was raised because a significant proportion of especially low-grade DCIS lesions never progress to invasive cancer. The rationale for the present study was to analyze the value of stereotactic vacuum-assisted biopsy (VAB) for complete removal of DCIS, focusing on the relationship between the absence of residual microcalcifications after stereotactic VAB and the histopathological diagnosis of the definitive surgical specimen. Patients and Methods: Data of 58 consecutive patients diagnosed with DCIS by stereotactic VAB in a single breast center between 2012 and 2017 were analyzed. Patient records from the hospital information system were retrieved, and mammogram reports and images as well as histopathology reports were evaluated. The extent of microcalcifications before and after biopsy as well as the occurrence of DCIS in biopsy and definitive surgical specimens were analyzed and correlated. Results: There was no correlation between the absence of residual microcalcifications in the post-biopsy mammogram and the absence of residual DCIS in the final surgical specimen (p = 0.085). Upstaging to invasive cancer was recorded in 4 cases (13%) but occurred only in the group that had high-grade DCIS on biopsy. Low-grade DCIS was never upgraded to high-grade DCIS in the definitive specimen. Conclusions: The radiological absence of microcalcifications after stereotactic biopsy does not rule out residual DCIS in the final surgical specimen. Since upstaging to invasive cancer is seen in a substantial proportion of high-grade DCIS, the surgical excision of high-grade DCIS should remain the treatment of choice.

Abstract Context Gynecomastia, the proliferation of mammary glandular tissue in the male, is a frequent but little-studied condition. Available prevalence data are based on selected patient populations or autopsy cases with their inherent bias. Objective The objective of this work is to evaluate the age-related incidence and secular trends in gynecomastia in the general population. Design An observational, 20-year national registry study was conducted. Setting This population-based study used nationwide registry data. Participants Participants included all Danish males (age 0-80 years) with a first-time diagnosis of gynecomastia. Main Outcome Measures All Danish males (age 0-80 years) were followed up for incident diagnosis of gynecomastia in the Danish National Patient Registry from 1998 to 2017 using the International Codes of Diseases, 10th revision, and the Danish Health Care Classification System. Age-specific incidence rates were estimated. The hypothesis tested in this study was formulated prior to data collection. Results Overall, a total 17 601 males (age 0-80 years) were registered with an incident diagnosis of gynecomastia within the 20-year study period, corresponding to 880 new cases per year and an average 20-year incidence of 3.4 per 10 000 men (age 0-80 years). The average annual incidence was 6.5/10 000 in postpubertal males age 16 to 20 years and 4.6/10 000 in males age 61 to 80 years, with a respective 5- and 11-fold overall increase in these 2 age groups over the 20-year period. Conclusions The incidence of gynecomastia has dramatically increased over the last 20 years, implying that the endogenous or exogenous sex-steroid environment has changed, which is associated with other adverse health consequences in men such as an increased risk of prostate cancer, metabolic syndrome, type 2 diabetes, or cardiovascular disorders.
