AIM To determine the prevalence of Chlamydia trachomatis (CT) and Neisseria gonorrhea (GC) in young men seeking care in the emergency department (ED) for non-sexually transmitted infection (STI) related symptoms. METHODS This was a prospective, cross-sectional study in an urban ED. The main outcome was the rate of positive CT and GC on urine nucleic acid amplification testing in males aged 16...

Objective To highlight the pattern of sexually transmitted infections (STIs) and the profile of patients with HIV infection in STI patients as seen at our hospital. Methods A retrospective analysis of records of patients attending the STD clinic during the period of September 2013 till August 2014 was done. Results A total of 90 patients attended the STD clinic, out of which 63 were males and 2...

We de ne a time-stepping procedure to integrate the equations of motion of sti multibody dynamics with contact and friction. The friction and non-interpenetration constraints are modelled by complementarity equations. Sti ness is accommodated by a technique motivated by a linearly implicit Euler method. We show that the main subproblem, a linear complementarity problem, is consistent for a su c...

BACKGROUND Sexually transmitted infections (STIs) remain a major public health problem in Zimbabwe. In Zvishavane, STI increased from 66 per 1,000 in 2002 to 97 per 1,000 in 2005, a 31% increase in cases. OBJECTIVE To determine the factors associated with contracting sexually transmitted infections (STI) among patients in Zvishavane. METHODS A frequency matched case control study was conduc...

Background While the conditions in emergency humanitarian and conflict-affected settings often result in significant sex work economies, there is limited information on the social and structural conditions of sex work in these settings, and the impacts on HIV/STI prevention and access to sexual and reproductive health (SRH) services for sex workers. Our objective was to comprehensively review e...

BACKGROUND In Germany, local public health departments (LPHD) are required to offer low-threshold access to confidential counselling and testing for sexually transmitted infections (STI) for sex workers. We collected data from LPHD in Germany to estimate the number of performed STI tests and the proportion of positive STI tests among attending female sex workers (FSW) in order to formulate reco...
