- Abstract
Background: As a potential indicator of equity in research partnerships, we conducted a bibliometric analysis of author affiliations and author order in publications about sub-Saharan Africa published in the journal Sexually Transmitted Diseases ., Methods: We identified articles in the journal Sexually Transmitted Diseases that were about sub-Saharan Africa and published from 2011 to 2020. Medical Subject Heading terms in PubMed were used to identity articles about sub-Saharan Africa. Authors with at least 1 affiliation in sub-Saharan Africa were characterized as sub-Saharan Africa-affiliated authors., Results: Of the 1439 articles that were published in Sexually Transmitted Diseases from 2011 to 2020, 148 (10%) had a Medical Subject Heading term for a sub-Saharan African country. Of the 604 authors of these 148 articles, 53 (36%) of the first authors, 493 (53%) of the middle authors, and 58 (40%) of the last authors had a sub-Saharan African affiliation; 13 (8.8%) of the articles had no authors with a sub-Saharan African affiliation. The proportions of sub-Saharan African-affiliated authors in first and last authorship positions did not change significantly from 2011-2015 (77 articles) to 2016-2020 (71 articles)., Conclusions: The underrepresentation of Africans in first and last authorship positions suggests power imbalances in global scientific partnerships. Funders, researchers, editors, publishers, and grant and manuscript reviewers each have roles in promoting equity in global health research. This study may serve as an example for journals to establish benchmarks and monitor progress toward a more equitable research environment., Competing Interests: Conflict of Interest and Sources of Funding: None declared., (Copyright © 2023 Written work prepared by employees of the Federal Government as part of their official duties is, under the U.S. Copyright Act, a “work of the United States Government” for which copyright protection under Title 17 of the United States Code is not available.

- Abstract
Introduction: Acquired epidermodysplasia verruciformis (EV) is a skin disorder that has been described in individuals with perinatally acquired HIV. Many cases have been identified in sub-Saharan Africa in keeping with the epidemiology of HIV infection compared to the rest of the world, where cases are rare. Epidermodysplasia verruciformis skin lesions may undergo malignant transformation. There are few documented cases of malignant transformation of these skin lesions. We describe a patient with an EV-like skin rash who developed cutaneous squamous cell carcinoma (SCC)., Patient Presentation: A 25-year-old man, on antiretroviral treatment for 12 years, presented with a generalised skin rash since the age of 11 years, and a 7-month history of a persistent scalp ulcer. He had no history of trauma, radiation or other chronic conditions. Despite an undetectable HIV viral load, he had failed to immune reconstitute (CD4 42 cells/µL). Physical examination revealed a generalised hypopigmented, papular skin rash resembling verruca plana and a 3 cm × 3 cm ulcer with rolled edges on the right parietal region of the scalp. There were no palpable lymph nodes in the head and neck areas. Biopsy of the ulcer revealed moderately differentiated SCC., Management and Outcome: Wide local excision of the lesion was done under local anaesthesia and histological analysis confirmed completely excised moderately differentiated SCC. Further examination four weeks later revealed two, smaller, histologically similar scalp lesions which were completely excised., Conclusion: Patients with acquired EV require thorough, frequent examination for skin lesions with possible malignant transformation. Early identification of malignant transformation and treatment with surgical intervention is curative., Competing Interests: The authors declare that they have no financial or personal relationships that may have inappropriately influenced them in writing this article., (© 2022.

- Abstract
Introduction: Sexually transmitted infections (STIs) remain prevalent and are increasing in several populations. Appropriate STI diagnosis is crucial to prevent the transmission and sequelae of untreated infection. We reviewed the diagnostic accuracy of syndromic case management and existing point-of-care tests (POCTs), including those in the pipeline, to diagnose STIs in resource-constrained settings., Methods: We prioritized updating the systematic review and meta-analysis of the diagnostic accuracy of vaginal discharge from 2001 to 2015 to include studies until 2018. We calculated the absolute effects of different vaginal flowcharts and the diagnostic performance of POCTs on important outcomes. We searched the peer-reviewed literature for previously conducted systematic reviews and articles from 1990 to 2018 on the diagnostic accuracy of syndromic management of vaginal and urethral discharge, genital ulcer and anorectal infections. We conducted literature reviews from 2000 to 2018 on the existing POCTs and those in the pipeline., Results and Discussions: The diagnostic accuracy of urethral discharge and genital ulcer disease syndromes is relatively adequate. Asymptomatic Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) infections limit the use of vaginal discharge and anorectal syndromes. The pooled diagnostic accuracy of vaginal syndromic case management for CT/NG is low, resulting in high numbers of overtreatment and missed treatment. The absolute effect of POCTs was reduced overtreatment and missed treatment. Findings of the reviews on syndromic case management underscored the need for low-cost and accurate POCTs for the identification, first, of CT/NG, and, second, of Mycoplasma genitalium (MG) and Trichomonas vaginalis (TV) and NG and MG resistance/susceptibility testing. Near-patient POCT molecular assays for CT/NG/TV are commercially available. The prices of these POCTs remain the barrier for uptake in resource-constrained settings. This is driving the development of lower cost solutions., Conclusions: The WHO syndromic case management guidelines should be updated to raise the quality of STI management through the integration of laboratory tests. STI screening strategies are needed to address asymptomatic STIs. POCTs that are accurate, rapid, simple and affordable are urgently needed in resource-constrained settings to support the uptake of aetiological diagnosis and treatment., (© 2019 World Health Organization; licensed by IAS.)

- Abstract
Many countries in Africa have weak surveillance systems for data collection of sexually transmitted infections, and hardly any programmes for gonococcal antimicrobial susceptibility assessment. The widespread adoption of the syndromic approach to the diagnosis and management of sexually transmitted infections has also meant that the collection of a genital specimen for laboratory analysis is no longer routinely done when patients present with genital complaints, and clinical staff and laboratory technicians have lost the skill to collect genital specimens and processing them for culture and antimicrobial susceptibility testing. Following reports of gonococcal antimicrobial resistance to quinolones, WHO urged countries to monitor gonococcal antimicrobial resistance in a more systematic and regular manner. Although the response in Africa has been slow to take off, a number of studies have been conducted in a few countries and plans for implementation are in place in others. However, the number of isolates studied has been small in nearly all the countries except one, and the barriers to scaling up gonococcal antimicrobial resistance surveys seem overwhelming. In spite of the studies being few and of small sample sizes, enough information can be discerned to indicate that quinolones can no longer be a medicine of choice for the treatment of gonorrhoea in Africa and the threat of antimicrobial resistance developing in Neisseria gonorrhoeae to third-generation cephalosporins is real and imminent.

- Abstract
Objectives: A survey was conducted to assess the adequacy of sexually transmitted infections (STI) prevention and control policies and programmes in the European region (including the central Asian republics)., Methods: An adapted World Health Organization (WHO) model questionnaire was sent to ministry of health officials in all 45 countries of Europe and central Asia. The questionnaire included questions on STI programme structure; STI case management; the different types and levels of services, including public and private service providers; partner notification and screening policies; services for vulnerable populations; monitoring and supervision; surveillance and research., Results: Western European countries largely leave STI prevention and care to individual practitioners. Licensed providers exist at all levels of care, and access to consultations and treatment is usually free of charge. In the newly independent states (NIS), by contrast, programme efforts emphasise state guidance and supervision of local providers rather than individual practitioners. Access to services is limited in that in several NIS, only public sector specialists are licensed to treat STI. Formerly free of charge policies have been severely eroded. While in western Europe access to condoms appears to be good, in the NIS there are many fewer condom outlets. Regionwide, in 40% of countries the distribution of condoms is part of STI consultations., Conclusions: Non-availability of affordable high quality STI services, including STI treatment and condoms, may be one of the causes for the much higher STI prevalence in parts of eastern Europe and NIS than in western Europe.
