Skin cancer and HIV.

The risk of skin cancer in persons living with HIV (PLWH) is an evolving subject area shaped by the use of antiretroviral therapy. Keratinocyte carcinomas, including basal cell carcinoma and squamous cell carcinoma, have a high incidence in the general population as well as in PLWH. PLWH may have a higher risk of squamous cell carcinoma when compared to the general population.

Global monkeypox outbreak 2022: First case series in Singapore.

Monkeypox is a global health emergency. Prior to 2022, there were few reports of monkeypox outside of endemic countries, which were mostly travel-related. Since May 2022, an exponential increase in monkeypox infections in previously non-endemic countries has been reported.

Effect of a Popular Web Drama Video Series on HIV and Other Sexually Transmitted Infection Testing Among Gay, Bisexual, and Other Men Who Have Sex With Men in Singapore: Community-Based, Pragmatic, Randomized Controlled Trial.

Background: Gay, bisexual, and other men who have sex with men (GBMSM) are at disproportionately higher risk of acquiring HIV and other sexually transmitted infections (STI). While HIV/STI testing rates among GBMSM are increasing worldwide, they remain suboptimal in a variety of settings. While many studies have attempted to evaluate the efficacy of a variety of community-based campaigns, including peer and reminder-based interventions on HIV/STI testing, however few have attempted to do so for a web drama series.

Potential interactions between the pathways to diagnosis of HIV and other STIs and HIV self-testing: insights from a qualitative study of gay, bisexual and other men who have sex with men in Singapore.

Objectives: This study draws on qualitative insights on the barriers and facilitators to HIV testing, as well as perceptions of HIV self-testing (HIVST), to propose a framework to understand not only the benefits but also potential knock-on implications of introducing HIVST in the context of other STI testing.

Methods: We conducted semistructured, in-depth interviews with 30 gay, bisexual and other men who have sex with men aged 18 and 39 years old in Singapore. Interview topics included barriers and facilitators to HIV and other STI testing, as well as perceptions of HIVST.

Mycoplasma genitalium in Singapore is associated with Chlamydia trachomatis infection and displays high macrolide and Fluoroquinolone resistance rates.

Background: Mycoplasma genitalium is an emerging sexually transmitted infection, with increasing rates of resistance to fluroquinolones and macrolides, the recommended treatments. Despite this, M. genitalium is not part of routine screening for Sexually Transmitted Infections (STIs) in many countries and the prevalence of infection and patterns of disease remain to be determined in many populations.

Effect of a web drama video series on HIV and other sexually transmitted infection testing among gay, bisexual and queer men: study protocol for a community-based, pragmatic randomised controlled trial in Singapore: the People Like Us (PLU) Evaluation Study.

Introduction: Gay, bisexual and queer (GBQ) men are at disproportionately higher risk of acquiring HIV and other sexually transmitted infections (STI). While HIV/STI testing rates among GBQ men are increasing worldwide, they remain suboptimal in a variety of settings.

Methods And Analysis: The study is a pragmatic randomised controlled trial designed to evaluate an online video series developed by a community-based organisation in Singapore for GBQ men.

Acceptability of HIV Pre-exposure Prophylaxis (PrEP) and Opinions on PrEP Service Delivery Among Men Who Have Sex With Men in Singapore: A Qualitative Study.

PrEP is effective in preventing HIV transmission among at-risk HIV-negative MSM. A qualitative descriptive study with five focus group discussions (N = 33) involving a purposively recruited sample of Singaporean MSM was conducted from August 2016 to April 2017 to understand local perspectives on potential barriers and motivators to the adoption of PrEP, prior to the implementation of PrEP services in Singapore. Knowledge of PrEP was high, and many viewed PrEP as an attractive alternative to condoms for HIV prevention.

Chemsex among gay, bisexual, and other men who have sex with men in Singapore and the challenges ahead: A qualitative study.

Background: Sexualised substance use, or 'chemsex' has been shown to be a major factor driving the syndemic of HIV/AIDS in communities of gay, bisexual, and other men who have sex with men (GBMSM) around the world. However, there is a paucity of research on chemsex among GBMSM in Singapore due to punitive drug laws and the criminalisation of sexual behaviour between men. This qualitative descriptive study is the first to explore perceptions towards, motivators to engaging in, and the barriers to addressing the harms associated with chemsex among GBMSM in Singapore.

A mixed methods study of non-occupational post-exposure prophylaxis at an STI clinic in Singapore: Five-year retrospective analysis and providers' perspectives.

Background: This mixed methods study aims to describe 1) characteristics of the population treated with non-occupational post-exposure prophylaxis (nPEP), 2) predictors of loss to follow-up (LTFU) and nPEP adherence, and 3) to evaluate the nPEP prescribing practices against current management guideline.

Methods: This study was conducted at the Department of Sexually Transmitted Infections Control Clinic in Singapore using clinical data from 2010 to 2016. Explanatory sequential mixed method design was adopted.

An Abstinence and Safer Sex Intervention for Adolescents Attending the Public Sexually Transmitted Infection Clinic in Singapore.

Purpose: The objective of this study was to evaluate the efficacy of a behavioral intervention in increasing secondary abstinence and safer sex among heterosexually active adolescents aged 16-19 years.

Methods: This was a randomized controlled trial conducted at the only national sexually transmitted infection clinic in Singapore. The intervention focused on information giving, motivation, and skills building to abstain or practice safer sex.

Subungual Squamous Cell Carcinoma: The Diagnostic Challenge and Clinical Pearls.

Subungual squamous cell carcinoma is a rare entity and difficult to diagnose as its clinical presentation may resemble benign conditions. This case report highlights the need to maintain a high clinical index of suspicion, and recommends a practical approach for subungual conditions. Dermoscopy and a biopsy for histology are important adjuncts to clinch the diagnosis.

Determinants of Chlamydia, Gonorrhea, and Coinfection in Heterosexual Adolescents Attending the National Public Sexually Transmitted Infection Clinic in Singapore.

Background: Amidst recent trends in rising rates of chlamydia and gonorrhea among Singaporean adolescents, there are limited data on risk factors associated with these infections that may inform prevention strategies in this population.

Methods: A cross-sectional study of chlamydia and gonorrhea positivity was conducted among 1458 sexually active heterosexual adolescents between 14 and 19 years old attending the national public sexually transmitted infection clinic from 2006 to 2013. The association with demographic and behavioral characteristics was assessed by crude prevalence ratio, and negative binomial regression modeling was used to obtain adjusted prevalence ratios (aPRs).

A prospective study on the use of teledermatology in psychiatric patients with chronic skin diseases.

Background: To compare the use of live interactive teledermatology versus conventional face-to-face consultation in long-term, institutionalised psychiatric patients with chronic skin diseases.

Methods: All institutionalised psychiatric patients at the Institute of Mental Health with follow-up appointments at the National Skin Centre were assessed for eligibility and invited to participate. Recruited patients were first seen by a dermatologist via videoconferencing, and then by another dermatologist in person, within 1 week.

Background/objectives: Cutaneous metastases occur in up to 10% of all visceral malignancies. This study aims to determine the clinico-epidemiological characteristics of patients diagnosed with cutaneous metastases at a leading Asian tertiary dermatological centre.

Methods: A retrospective chart review was carried out on all patients diagnosed with cutaneous metastases from 2001 to 2010, identified through the National Skin Centre's clinical and histological databases.

Assessment of psychosocial impact of genital warts among patients in Singapore.

Unlabelled: Background Genital warts (GW) are a common sexually transmissible infection (STI) among young adults and are associated with poor quality of life (QoL). We investigated the functional and psychosocial effect of GW on Singaporean patients and evaluated for any variations in QoL between genders.

Methods: Patients with GW completed a standard questionnaire containing the Short Form-36 (SF-36) health survey and the Cuestionario Específico para Condiloma Acuminado in a cross-sectional survey.

Development and clinical validation of a multiplex real-time PCR assay for herpes simplex and varicella zoster virus.

Herpes simplex virus (HSV) and varicella zoster virus (VZV) are related members of the Herpesviridae family and are well-documented human pathogens causing a spectrum of diseases, from mucocutaneous disease to infections of the central nervous system. This study was carried out to evaluate and validate the performance of a multiplex real-time polymerase chain reaction (PCR) assay in detecting and differentiating HSV1, HSV2, and VZV from clinical samples. Consensus PCR primers for HSV were designed from the UL30 component of the DNA polymerase gene of HSV, with 2 separate hydrolysis probes designed to differentiate HSV1 and HSV2.
