REVIEW
Karl Egil Malterud
The ethnopharmacology, chemistry and pharmacology of four Malian medicinal plants, Biophytum umbraculum, Burkea africana, Lannea velutina and Terminalia macroptera are reviewed. These plants are used by traditional healers against numerous ailments: malaria, gastrointestinal diseases, wounds, sexually transmitted diseases, insect bites and snake bites, etc. The scientific evidence for these uses is, however, limited. From the chemical and pharmacological evidence presented here, it seems possible that the use in traditional medicine of these plants may have a rational basis, although more clinical studies are needed...

The main challenges facing efforts to prevent the transmission of human immunodeficiency virus (HIV) are the lack of access to sexual education services and sexual violence against young women and girls. Vaginal formulations for the prevention of sexually transmitted infections are currently gaining importance in drug development. Vaginal mucoadhesive tablets can be developed by including natural polymers that have good binding capacity with mucosal tissues, such as chitosan or guar gum, semisynthetic polymers such as hydroxypropylmethyl cellulose, or synthetic polymers such as Eudragit(®) RS...

Attempts to produce a vaccine to protect against Chlamydia trachomatis (C. trachomatis) induced trachoma were initiated more than 100 years ago and continued for several decades. Using whole organisms protective responses were obtained. However, upon exposure to C. trachomatis, disease exacerbation developed in some immunized individuals precluding the implementation of the vaccine. Evidence of the role of C. trachomatis as a sexually transmitted pathogen started to emerge in the 1960's and soon became evident that it can cause acute infections and long term-sequelae in women, men and newborns...

African-American males ages 13 through 24 are disproportionately affected by sexually transmitted infections (STIs) and human immunodeficiency virus (HIV), accounting for over half of all HIV infections in this age group in the United States. Clear communication between African-American parents and their youth about sexual health is associated with higher rates of sexual abstinence, condom use, and intent to delay initiation of sexual intercourse. However, little is known about African-American fathers' perceptions of what facilitates and inhibits sexual health communication with their preadolescent and adolescent sons...

PURPOSE OF REVIEW: The purpose of this article is to review what is currently known about Zika virus (ZIKV) disease and associated neurologic complications. RECENT FINDINGS: ZIKV is a mosquito-borne or sexually transmitted flavivirus rapidly spreading throughout the Americas. While ZIKV infection is usually asymptomatic, it may cause a non-specific illness with fever, rash, myalgia, headache, and/or non-purulent conjunctivitis. Additionally, ZIKV has been associated with a number of neurologic complications including microcephaly and other birth defects, Guillain-Barré syndrome, meningoencephalitis, myelitis, and various ophthalmologic abnormalities...

The aim of this study was to identify risk perceptions after human papillomavirus (HPV) vaccination among HIV-infected young men who have sex with men. On average, participants appropriately perceived themselves to be at lower than neutral risk for HPV (mean subscale score 4.2/10), at higher than neutral risk for other sexually transmitted infections (7.0/10), and that safer sexual behaviors were still important (8.5/10). Higher perceived risk of HPV was associated with African-American race (p = .03); higher perceived risk of other sexually transmitted infections with White race (p = ...

Somatic symptom disorder (SSD) often leads to frequent doctor visit not only to psychiatrists but also to various kinds of physicians. We encountered four cases of SSD, particularly associated with sexual intercourse and fear of sexually transmitted diseases (STDs). To best of our knowledge, there is no independent clinical entity assigned to this phenomenon. Here, we propose a variation of SSD called four STD as an independent clinical entity since the presentation of this disorder is very distinctive, and lack of awareness of it may lead to unnecessary laboratory workup and antimicrobial prescription as well as augmented anxiety of the patients with potential "doctor shopping...

Chlamydia trachomatis is the leading cause of bacterial sexually transmitted infections (STIs) and preventable blindness. Untreated, asymptomatic infection as well as frequent re-infection are common and may drive pelvic inflammatory disease, ectopic pregnancy, and infertility. In vivo models of chlamydial infection continue to be instrumental in progress toward a vaccine and further elucidating the pathogenesis of this intracellular bacterium, however significant gaps in our understanding remain. Chlamydial host cell exit occurs via two mechanisms, lysis and extrusion, although the latter has yet to be reported in vivo and its biological role is unclear...

Sexually transmitted infections (STIs) are caused by a wide variety of bacteria, viruses, and parasites that are transmitted from one person to another primarily by vaginal, anal, or oral sexual contact. Syphilis is a serious disease caused by a sexually transmitted infection. Syphilis is caused by the bacterium Treponema pallidum subspecies pallidum. Treponema pallidum (T. pallidum) is a motile, gram-negative spirochete, which can be transmitted both sexually and from mother to child, and can invade virtually any organ or structure in the human body...

Sexual abuse is a problem of epidemic proportions in the United States. In their practice, pediatric nurse practitioners will likely encounter children who have experienced sexual abuse-both those who have and have not previously been identified as victims. Sexually transmitted infections (STIs) are rare in sexually abused children and adolescents. However, when present, they can be crucial to making the diagnosis of sexual abuse and protecting children. This continuing education article will assist the pediatric nurse practitioner in interpreting the relationship between STIs and sexual abuse, correctly testing for STIs, and treating STIs in children and adolescents...

BACKGROUND: Chlamydia trachomatis is the most common bacterial sexually transmitted infection (STI) in the United States (U.S.) [1] and remains a major public health problem. We determined the cost- benefit of screening all pregnant women aged 15-24 for Chlamydia trachomatis infection compared with no screening. METHODS: We developed a decision analysis model to estimate costs and health-related effects of screening pregnant women for C. trachomatis in a high burden setting (Brooklyn, NY)...

BACKGROUND: A method is outlined for the use of an individual-based stochastic model of parasite transmission dynamics to assess different designs for a cluster randomized trial in which mass drug administration (MDA) is employed in attempts to eliminate the transmission of soil-transmitted helminths (STH) in defined geographic locations. The hypothesis to be tested is: Can MDA alone interrupt the transmission of STH species in defined settings? Clustering is at a village level and the choice of clusters of villages is stratified by transmission intensity (low, medium and high) and parasite species mix (either Ascaris, Trichuris or hookworm dominant)...

OBJECTIVE: The aim was to analyse those syndromes without fever in travellers who return from tropical regions evaluated at our Department of Infectology and Tropical Medicine. Clarifying these conditions intends to reach earlier diagnoses and, perhaps, to avoid the emergence and spread of imported diseases, as well as to establish appropriate preventive measures. METHODS: An observational descriptive transversal study was performed, selecting those patients who returned from tropical regions without fever (n = 281), amongst all travellers evaluated in our department between 1998 and 2013...

BACKGROUND: Human trichomoniasis caused by Trichomonas vaginalis is one of the most common sexually transmitted diseases with more than 200 million cases worldwide. It has caused a series of health problems to patients. For prevention and control of infectious diseases, vaccines are usually considered as one of the most cost-efficient tools. However, until now, work on the development of T. vaginalis vaccines is still mainly focused on the screening of potential immunogens. Alpha-actinin characterized by high immunogenicity in T...

INTRODUCTION: HIV testing and counselling (HTC) interventions are key to controlling the HIV epidemic in East and Southern Africa where HTC is primarily delivered through voluntary counselling and testing (VCT), provider initiated testing and counselling (PITC), and home-based counselling and testing (HBVCT). Decision making processes around uptake of HTC models must be taken into account when designing new interventions. Counselling in HTC aims to reduce post-test risk taking behaviour and to link individuals to care but its efficacy is unclear...

To date there is no commercially-available serodiagnostic for women and men infected with Trichomonas vaginalis. Thirteen epitopes of the immunogenic T. vaginalis α-actinin (106.2-kDa) are detected by sera of women patients, and 5 epitopes, a subset of the 13, are detected by sera of men. A truncated recombinant protein called ACT-P2 (63.5-kDa) encoding the 5 epitopes is used for screening by ELISA for antibody in sera of women and men. Because ACT-P2 is poorly expressed in E. coli, we wanted alternative recombinant α-actinin proteins as serodiagnostic targets...
