Sequential Cross-Sectional Surveys in Orange Farm, a Township of South Africa, Revealed a Constant Low Voluntary Medical Male Circumcision Uptake amo…
2016
Background WHO recommends a male circumcision (MC) prevalence rate higher than 80% to have a substantial impact on the HIV-AIDS epidemic in Eastern and Southern Africa. Orange Farm, a township in South Africa, has a free-for-service voluntary medical male circumcision (VMMC) clinic in operation since 2008. Following an intense campaign from 2008 to 2010, MC prevalence rate increased to 55.4% (ANRS-12126). Ongoing and past VMMC campaigns focused on youths, through school talks, and adults at a community level. The main objective of the study was to assess the change in MC prevalence rate among adults aged 18–19 and 18–49 years in the past 5 years. Methods A cross-sectional survey (ANRS-12285…
[Current developments and perspectives on the diagnosis and treatment of urinary incontinence and genital prolapse in women].
2012
As a key area of gynaecology, urogynaecology has undergone impressive changes in the past few years. Together with the high prevalence of functional pelvic floor disorders, modern anaesthesia procedures and the introduction of new, innovative minimally invasive operation techniques have led to a dramatic increase in the number of operations for incontinence and prolapses. The increasingly subtle diagnostic options, such as, e. g., 2D and 3D sonography of the pelvic floor provide unambiguous findings and facilitate decision making. Tension-free vaginal slings in retro-pubic, trans-obturator or single-incision techniques show a high success rate with few complications and have almost complete…
Evaluating diagnostic indicators of urogenital Schistosoma haematobium infection in young women: A cross sectional study in rural South Africa
2018
BackgroundUrine microscopy is the standard diagnostic method for urogenital S. haematobium infection. However, this may lead to under-diagnosis of urogenital schistosomiasis, as the disease may present itself with genital symptoms in the absence of ova in the urine. Currently there is no single reliable and affordable diagnostic method to diagnose the full spectrum of urogenital S. haematobium infection. In this study we explore the classic indicators in the diagnosis of urogenital S. haematobium infection, with focus on young women.MethodsIn a cross-sectional study of 1237 sexually active young women in rural South Africa, we assessed four diagnostic indicators of urogenital S. haematobium…
Mapping schistosoma haematobium for novel interventions against female genital schistosomiasis and associated HIV risk in kwazulu-natal, South Africa
2021
Abstract.Women with female genital schistosomiasis (FGS) have been found to have genital symptoms and a three-fold higher risk of HIV infection. Despite WHO recommendations, regular antischistosomal mass drug administration (MDA) has not yet been implemented in South Africa possibly because of the lack of updated epidemiological data. To provide data for future prevention efforts against FGS and HIV, this study explored Schistosoma haematobium prevalence in girls and young women and the effects of antischistosomal MDA, respectively. Urinary schistosomiasis and genital symptoms were investigated in 70 randomly selected secondary schools in three districts within KwaZulu-Natal and 18 primary …
Sexual Selection Within the Female Genitalia in Lepidoptera
2015
The genitalia of male and female Lepidoptera are complex organs, composed of several structures that exhibit great diversity of shapes, sizes, and positions, suggesting that they have evolved in a relatively rapid and divergent way. In this chapter, we explore the selective pressures responsible for the evolution of genital morphology in the Lepidoptera , emphasizing the possible role of post-copulatory intersexual selection (PCIS) mechanisms (cryptic female choice and sexual conflict). Our exploration is in great extent speculative because knowledge on the functional morphology of genitalia in this group is limited. We start by describing the complexity and diversity of genitalia in Lepido…
The Peculiarities of Gonad Transformation in Teleosts
1983
In teleosts the problem of sex determination and sex differentiation is more puzzling than in other vertebrates. It is not known whether the intriguing variety in the conditions of sex results from the position of these fishes within the vertebrate pedigree. They represent the final products of actinopterygian evolution toward the end of the age of reptiles, that is late in the Jurassic era. However, with that evolutionary fact in mind it is more plausible that teleosts deviate in many ways from the pattern that we are used to attribute to vertebrates in general. The following features of sex differentiation are striking examples of teleost peculiarity: (1) In both sexes there is no morphol…
Complementary and Innovative Method in Genital HPV Testing for Cervical Cancer Prevention
2020
Abstract Considering actual SARS-COV 2 pandemic, the comfort and time of the female patient’ trend is to minimize the time spent in the doctor’s office, so that auto-testing is a solving problem in this context. This paper aims at the importance of self-collected urine and vaginal samples, since actual studies are showing that is a complementary method in HPV-testing and a screening method for prevention of cervical cancer. Genital HPV infection is responsible for approximately 99% of cervical cancers, and is considered a sexually transmitted disease. Given that eight out of ten patients have at least one episode of HPV infection in their lifetime, there is a need for a method of early dete…
Association of Urogenital Symptoms with History of Water Contact in Young Women in Areas Endemic for S. haematobium. A Cross-Sectional Study in Rural…
2016
Female genital schistosomiasis is a neglected tropical disease caused by Schistosoma haematobium. Infected females may suffer from symptoms mimicking sexually transmitted infections. We explored if self-reported history of unsafe water contact could be used as a simple predictor of genital schistosomiasis. In a cross-sectional study in rural South Africa, 883 sexually active women aged 16–22 years were included. Questions were asked about urogenital symptoms and water contact history. Urine samples were tested for S. haematobium ova. A score based on self-reported water contact was calculated and the association with symptoms was explored while adjusting for other genital infections using m…
Spontaneous extrusion of male genital pearling
2021
Pearling is a practice of inserting small beads beneath the skin of the genitalia. Patients generally underwent this practice believing that this would have made their penis bigger and able to better satisfy their partners during intercourse. Pearling can cause complications. We report a case of spontaneous extrusion of genital pearling exiting in a granuloma of the inner face of the foreskin.
S. haematobium as a Common Cause of Genital Morbidity in Girls: A Cross-sectional Study of Children in South Africa
2013
Background Schistosoma (S.) haematobium infection is a common cause of genital morbidity in adult women. Ova in the genital mucosal lining may cause lesions, bleeding, pain, discharge, and the damaged surfaces may pose a risk for HIV. In a heterogeneous schistosomiasis endemic area in South Africa, we sought to investigate if young girls had genital symptoms and if this was associated with urinary S. haematobium. Methodology In a cross-sectional study of 18 randomly chosen primary schools, we included 1057 schoolgirls between the age of 10 and 12 years. We interviewed assenting girls, whose parents had consented to their participation and examined three urines from each of them for schistos…
