RESUMO
Sexually Transmitted Infections (STIs) are a critical global health concern, with low- and middle-income countries carrying the highest burden. The development of rapid point-of-care STI tests has enabled screening in settings without laboratory access. Yet, high-need settings face unique challenges that may influence the implementation and uptake of STI screening. This piece discusses lessons learned from the implementation of STI screening in a rural, low-resource setting in Chiapas, Mexico. Despite minimal privacy and a low staff-to-patient ratio, a streamlined approach was developed to destigmatize and maximize STI screening. The clinic team developed strategies through practice, including incorporating screening into triage procedures and offering screening to family members. This protocol led to an average screening rate of 37% within three months and acceptance of screening by family units. It was observed that access to treatment was necessary to alleviate patient hesitation to screening due to fears of a positive result. As STI screening increases globally, healthcare systems must develop robust access to treatment to effectively prevent and treat STIs worldwide.
RESUMO
BACKGROUND: Transactional sex relationships (TSRs) create financial and emotional support for men and women, as well as an increased sexual risk. Studies have reported high HIV and STI transmission rates among young women in transactional sex relationships. However, little is known about TSR prevalence in Jamaica and risky sexual practices among participants. This study investigates the sexual behaviour of Jamaicans in TSR. METHODS: Secondary data analysis of a national survey revealed that 586 participants (38%) self-reported being in at least one TSR in the last 12 months. We also identified a third category called "Benefluids", who play both roles of benefactor and beneficiary in transactional sex relationships. RESULTS: 59 percent of male Benefluids had two to five transactional sex relationship partners in the last 12 months, compared to 40% of female Benefluids. Twenty-eight percent of female Benefluids reported sexually transmitted infection symptoms in the last 12 months compared to 13.5% of male Benefluids. While females reported more sexually transmitted infection symptoms, young men had the highest sexual risk precursors. CONCLUSIONS: People in transactional sex relationships often play the role of beneficiaries and benefactors to meet material and sexual needs but this increases the risk of STI symptoms.

Monkeypox is a zoonotic viral disease caused by a virus of the genus Orthopoxvirus. As of January 1, 2022, it has been reported in 110 WHO Member States. It presents with fever, fatigue, painful lymphadenopathy, and rash. It lasts between 2 and 4 weeks. It is usually self-limited, but severe cases have been described in immunocompromised people. This study describes cases of monkeypox in women, diagnosed between June 2022 and February 2023, and it reports epidemiology, clinical aspects, and complications after infection. A retrospective observational study was carried out in the Febrile Emergency Unit (UFU), reviewing positive cases (RT-PCR) for monkeypox and the population with female biological sex was selected. They were questioned about gynecological complications, menstrual pattern, dyspareunia and pelvic pain. 340 consultations for monkeypox were made, 214 (63%) were positive, 211 cases (99%) male and 3 cases (1%) female. Among these cases is a trans woman, who was not included. The average age is 31 years, immunocompetent, with a negative serology report for HIV, syphilis, hepatitis B and C. Both cases had sexual intercourse without a barrier method. The most frequent symptoms are asthenia and skin lesions, especially in the upper and lower limbs, perianal and genital region. As a risk factor they presented unprotected sexual contact. Within the differential diagnoses, other sexually transmitted infections (STIs) should be considered. There were no gynecological complications reported during follow-up.
La viruela símica es una enfermedad viral zoonótica debida a un virus del género Orthopoxvirus. Desde el 1 de enero de 2022, se ha notificado en 110 Estados Miembros de la OMS. Se presenta con fiebre, astenia, linfoadenopatías dolorosas y exantema. Dura entre 2 y 4 semanas. Suele ser autolimitada y se han descrito casos graves en personas inmunocomprometidas. El presente trabajo describe casos de viruela símica en mujeres, diagnosticados entre junio del 2022 y febrero del 2023 Se realizó un estudio observacional retrospectivo en la Unidad Febril de Urgencias (UFU), revisando casos positivos (RT-PCR) para viruela símica y se seleccionó la población con sexo biológico femenino. Se consultó sobre complicaciones ginecológicas, patrón menstrual, dispareunia y dolor pélvico. Se realizaron 340 consultas por viruela símica, 214 (63%) fueron positivos, 211 casos (99%) de sexo masculino y 3 casos (1%) femeninos. Dentro de estos casos se encuentra una mujer trans, la cual no se incluyó. La edad promedio es de 31 años, inmunocompetentes, con reporte de serologías negativas para HIV, sífilis, hepatitis B y C. Ambos casos mantuvieron relaciones sexuales sin método de barrera. Los síntomas más frecuentes fueron astenia y lesiones en piel, sobre todo en miembros superiores e inferiores, región perianal y genital. Como factor de riesgo presentaron contacto sexual sin protección. Dentro de los diagnósticos diferenciales, debe tenerse en cuenta otras infecciones de transmisión sexual (ITS). En seguimiento epidemiológico no refirieron complicaciones ginecológicas.

BACKGROUND: Sexually transmitted infections (STIs) and STI treatment remain a challenge in public health. There is little understanding of related factors influencing health seeking behaviour and delay of care among clinic attendees in Jamaica. AIM: To determine socio-demographic profile of clinic attendees with STI and identify factors associated with delay in seeking care for STI-related symptoms. METHODS: A cross-sectional study was done. 201 adult patients presenting with STI symptoms from four health centres in Kingston and St Andrew were selected. A 24-item interviewer-assisted questionnaire was used to obtain data on socio-demographic characteristics, patients' symptoms and duration, previous STIs, knowledge of complications and seriousness of STIs, and factors influencing decision to seek medical care. RESULTS: Almost 75% delayed seeking care for STIs. Recurrent STIs was identified in 41% of patients. 'Could not find time' was the most commonly reported reason for delay in seeking care (36%). Females were 3.4 times more likely to delay seeking care for STI symptoms than males (OR 3.42, 95% CI: 1.73-6.73). Those with primary level education and below were 5 times more likely to delay seeking care for STI symptoms than those with at least secondary level education (OR 5.05, 95% CI: 1.09-23.46). Participants viewed staff as confidential (68%) and 65% thought health-care workers spent adequate time during consultations. CONCLUSION: Lower education level and the female gender are associated with delay in seeking care for STI-related symptoms. These factors should be considered when developing interventions to reduce delay in care for STI-related symptoms.

ABSTRACT Background: Syphilis is associated with social and behavioral factors. Methods: This cross-sectional study determined the prevalence of syphilis and its associated risk factors among recyclable waste collectors in Central Brazil. Results: A lifetime syphilis prevalence rate of 7.91% (95% confidence interval: 5.25-11.75) was found among 278 participants. Low educational level, history of sexually transmitted infection, and age ≥ 36 years were associated with a high prevalence of lifetime syphilis. Conclusions: These findings emphasize the need for syphilis prevention, screening, and treatment among recyclable waste collectors, highlighting the potential for the spread of infection in vulnerable populations.
RESUMO
Resumen Antecedentes: Las infecciones de transmisión sexual son un problema de salud pública mundial. El análisis rutinario incluye solo pruebas microbiológicas y serológicas para el diagnóstico de patógenos. Los microorganismos atípicos como Chlamydia trachomatis y micoplasmas no son identificados debido a los requerimientos. Además, no es incluida Gardnerella vaginalis, aunque se asocia a la vaginosis bacteriana. Objetivo: Desarrollar una PCR múltiplex para el diagnóstico de C. trachomatis, micoplasmas y G. vaginalis. Método: Se estandarizó la PCR múltiplex utilizando oligonucleótidos para C. trachomatis (gen ompA, orf6 plasmídico), Mycoplasma/Ureaplasma y G. vaginalis (genes rRNA16s). Resultados: Se estandarizaron pruebas de PCR múltiplex para los microorganismos estudiados, optimizándose las concentraciones y condiciones de las reacciones múltiplex. Se obtuvieron PCR dúplex para C. trachomatis (ompA, orf6), Chlamydia/Gardnerella y Chlamydia/micoplasmas y tríplex para Chlamydia/Mycoplasma/Ureaplasma. También un cuádruplex para Chlamydia/Mycoplasma/Ureaplasma/Gardnerella. Los resultados fueron verificados por PCR e hibridación automática (HybriSpot 12) y análisis in silico. Conclusión: Se desarrollaron pruebas de PCR múltiplex con una alta sensibilidad y especificidad para la identificación de C. trachomatis, micoplasmas y G. vaginalis.
Abstract Background: Sexually transmitted infections are a global public health problem. Routine analysis includes microbiological and serological tests for the diagnosis of pathogens. Atypical microorganisms such as Chlamydia trachomatis and mycoplasmas are not determined due to the requirements for their identification. Furthermore, Gardnerella vaginalis is not included despite being associated with bacterial vaginosis. Objective: To develop a multiplex PCR to diagnose Chlamydia, mycoplasmas, and Gardnerella. Method: Standardization of multiplex PCR tests was carried out using oligonucleotides for the identification of Chlamydia (ompA gene, plasmid orf6), Mycoplasma/Ureaplasma and Gardnerella (rRNA16s genes). Results: Multiplex PCR tests were standardized for the microorganisms studied, optimizing the concentrations and conditions of the multiplex reactions. Duplex PCR was obtained for Chlamydia (ompA, orf6), Chlamydia/Gardnerella, and Chlamydia/mycoplasmas, and triplex PCR for Chlamydia/mycoplasmas. Also, a quadruplex for Chlamydia, Mycoplasma/Ureaplasma and Gardnerella. PCR and automatic hybridization verified the results obtained (HybriSpot 12) and in silico analysis. Conclusion: Multiplex PCR tests with high sensitivity and specificity were developed to identify C. trachomatis, mycoplasmas, and G. vaginalis.
RESUMO
Objectives: The study aims to identify the correlation between human papillomavirus (HPV) infection and sociodemographic and sexual reproductive health factors in Ecuadorian women from March to August 2019. Methods: 120 women were randomly selected from two gynecological clinics to complete a questionnaire and provide a biospecimen. PCR-Hybridization was used to genotype 37 HPV serotypes in samples obtained by endo-cervical brushing for liquid-based cytology. Sociodemographic and sexual health data were collected through a validated questionnaire during a medical consultation. Mathematical modeling of HPV infection was done using bivariate logistic regression. Results: 65.0% of the women sampled had an HPV infection; 74.3% of these women had co-infections with other HPV genotypes. Out of the women who were HPV positive, 75.6% were diagnosed with high-risk genotypes from HPV strains 18, 35, 52, and 66. Parity, immunosuppression, and use of oral contraception/intrauterine devices (IUDs) were identified as associated variables. The explanatory model had a sensitivity of 89.5% and a specificity of 73.8%. Conclusion: The predominant strains of HPV among Ecuadorian women are diverse. The risk of HPV infection is a complex phenomenon where biological and psychosocial variables are integrated into a model. In populations with limited access to health services, low socioeconomic status, and negative sociocultural beliefs about sexually transmitted infections (STIs), surveys can be used as a pre-screening step for HPV infections. The diagnostic value of the model should be tested in multicenter studies that include women from all over the country.

The world is heading towards an era of intractable and impending untreatable N. gonorrhoeae, thereby underlining the significance of rapid and accurate prediction of drug resistance as an indispensable need of the hour. In the present study, we optimized and evaluated a stable isotope labeling-based approach using the MALDI-TOF MS (Matrix-Assisted Laser Desorption/Ionization-Time of Flight Mass Spectrometry) for rapid and reliable detection of ciprofloxacin and azithromycin resistance in N. gonorrhoeae. All the isolates were cultured under three varied condition setups viz. medium supplemented with normal lysine, heavy lysine (isotope), and heavy lysine along with the antibiotics (ciprofloxacin/azithromycin), respectively. After incubation, spectra were acquired using the MALDI-TOF MS which were further screened for unique patterns (media-specific spectra) to differentiate drug-susceptible and resistant isolates. The results of the stable isotope labeling assay were comparable to the results of phenotypic methods used for susceptibility testing.

BACKGROUND: Worldwide, a significant proportion of head and neck cancers is attributed to the Human papillomavirus (HPV). It is imperative that we acquire a solid understanding of the natural history of this virus in head and neck squamous cell carcinoma (HNSCC) development. Our objective was to investigate the role of sexual behaviour in the occurrence of HNSCC in the French West Indies. Additionally, we evaluated the association of high risk of HPV (Hr-HPV) with sexual behaviour in risk of cancer. METHODS: We conducted a population-based case-control study (145 cases and 405 controls). We used logistic regression models to estimate adjusted odds-ratios (OR), and their 95% confidence intervals (CI). RESULTS: Compared to persons who never practiced oral sex, those who practiced at least occasionally had a lower HNSCC risk. First sexual intercourse after the age of 18 year was associated with a 50% reduction of HNSCC risk, compared to those who began before 15 years. HNSCC risk was significantly reduced by 60% among persons who used condoms at least occasionally. The associations for ever condom use and oral sex were accentuated following the adjustment for high-risk HPV (Hr-HPV). Oral Hr-HPV was associated with several sexual behaviour variables among HNSCC cases. However, none of these variables were significantly associated with oral HPV infections in the population controls. CONCLUSION: First intercourse after 18 years, short time interval since last intercourse and ever condom use were inversely associated with HNSCC independently of oral Hr-HPV infection. Sources of transmission other than sexual contact and the interaction between HPV and HIV could also play a role in HNSCC etiology.

Introduction: Maternal and child health are essential to public health, especially during pregnancy, where urogenital infections can affect mothers and fetuses. Sexually transmitted infections (STIs) increase obstetric risks and have complex connections with the human immunodeficiency virus HIV. In Brazil, pregnant women with HIV are a growing concern, requiring focus and appropriate interventions. Objective: This study aimed to examine the clinical and epidemiological characteristics of urogenital infections in pregnant women with and without HIV and to assess whether there are notable differences between these groups. Methods: A scoping review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR) and Joanna Briggs Institute guidelines. Databases such as Medical Literature Analysis and Retrieval System Online (MEDLINE), Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS), and Scientific Electronic Library Online (SciELO) were explored using relevant terms. Inclusion/exclusion criteria selected nine studies for analysis. A Population, Intervention, Comparison, Outcome, and Study Design (PICOS) approach directed the search. Results: Pregnant women with HIV had a high prevalence of STIs, including Chlamydia trachomatis, Neisseria gonorrhoeae, Trichomonas vaginalis, and bacterial vaginosis. HIV infection appears to influence the risk and severity of urogenital infections. Pregnancy increases the risk of STIs, regardless of HIV status. Male partners may also influence the presence of STIs in pregnant women, especially those with HIV. Conclusion: This study highlights the association between HIV status and urogenital infections in pregnant women, indicating the need for appropriate screening and care. Prevention and treatment of STIs in pregnant women are essential for maternal and child health, regardless of HIV status. An in-depth understanding of these issues can improve public policies, clinical practices, and preventive interventions that target the overall health of these vulnerable populations.Keywords: HIV. Signs and symptoms. Female urogenital diseases and pregnancy complications. Pregnant women. Sexually transmitted infections
Introdução: A saúde materna e infantil é essencial na saúde pública, especialmente durante a gravidez, quando infecções urogenitais podem afetar mães e fetos. Infecções sexualmente transmissíveis (IST) aumentam riscos obstétricos e têm conexões complexas com o vírus da imunodeficiência humana (HIV). No Brasil, gestantes com HIV são uma preocupação crescente, requerendo foco e intervenções adequadas. Objetivo: Este estudo teve como objetivo examinar as características clínicas e epidemiológicas das infecções urogenitais em mulheres grávidas com e sem HIV, avaliando se há diferenças notáveis entre esses grupos. Métodos: Uma revisão de escopo foi conduzida, seguindo as diretrizes Preferred Reporting Items for Systematic Reviews and Meta-Analyses - Extension for Scoping Reviews(PRISMA-ScR) e Joanna Briggs Institute. Bases de dados como Medical Literature Analysis and Retrieval System Online (MEDLINE), Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS), and Scientific Electronic Library Online (SciELO) foram exploradas com termos relevantes. Os critérios de inclusão/exclusão selecionaram nove estudos para análise. Uma abordagem do tipo População, Intervenção, Comparação, Desfecho e Desenho do Estudo (PICOS) direcionou a pesquisa. Resultados: Mulheres grávidas com HIV apresentaram alta prevalência de IST, incluindo Chlamydia trachomatis, Neisseria gonorrhoeae, Trichomonas vaginalis e vaginose bacteriana. A infecção por HIV parece influenciar o risco e a gravidade das infecções urogenitais. A gravidez aumentou o risco de IST, independentemente do status de HIV. Os parceiros masculinos também podem influenciar a presença de IST em mulheres grávidas, especialmente aquelas com HIV. Conclusão: A associação entre o status de HIV e as infecções urogenitais em mulheres grávidas indica a necessidade de rastreamento e cuidado adequado. A prevenção e o tratamento de IST em gestantes são essenciais para a saúde materno-infantil, independentemente do status de HIV

Background: The foot transit of migrant peoples originating from the Caribbean, South America, Asia, and Sub-Saharan Africa through the Darién Forest (DF) in Eastern Panamá towards North America has increased in recent years from approximately 30,000 people/year to >133,000 in 2021. In the DF, there is no food/housing provision nor healthcare access. Very little is known of sexual and reproductive health (SRH) among this population. This study used rapid epidemiological methods to describe the SRH situation among migrant peoples in transit through the DF. Methods: This cross-sectional study randomly selected migrant people in transit (men and women) at a Migrant Reception Station in Darién, Panamá, between January 4-11, 2022. Data collection included a self-applied questionnaire (≥18 years); clinical screening (≥12 years); and HCG, treponemal antibodies, and HIV(I/II) lateral-flow tests with blood samples (≥12 years). Descriptive analyses were used to report findings. Results: In all, 69 men and 55 women participated in the self-applied questionnaire, 70 men and 51 women in clinical screening; 78 men and 63 women in HCG, treponemal antibody and HIV testing. Overall, 26.1% (18/69) men and 36.4% (20/55) women reported sexual intercourse within the past month. The last sex partner was casual among 43.0% (21/49) of men and 27.8% (10/36) of women; of those, 42.9% (9/21) of men and 80.0% (8/10) of women reported this sex was condomless. Among women, 20.0% (11/55) tested positive for pregnancy; 5 of these pregnancies were planned. Of those screened, a reproductive tract infection symptom was reported by 5.7% (4/70) of men and 58.8% (30/51) of women. A total of 32.7% (18/55) of men and 18.2% (8/44) of women reported no prior HIV testing. Of 78 men, HIV and treponemal antibodies were found among 1.3% (n = 1) and 2.6% (n = 2), and among 63 women, 3.2% (n = 2) and 3.2% (n = 2), respectively. Conclusions: This rapid epidemiological assessment found high recent sexual activity, low condom use with casual partners, and a need for increased HIV and syphilis testing and treatment. There is a need for increased testing, condom provision, and SRH healthcare access at migrant reception stations that receive migrant peoples in transit through Panamá.
RESUMO
OBJECTIVE: To determine the prevalence of HPV and investigate factors associated with the infection in women in the city of Francisco Beltrão, southwest Paraná, attending the public health system. METHODS: This cross-sectional study included 324 women, aged between 18 and 65 years, who were attending public health services for routine gynecological consultation. Interviews were conducted to obtain information about socioeconomic, sexual, gynecological, and life habits. After performing the Papanicolaou test, endocervical brush was employed to detect HPV by polymerase chain reaction with the primers MY09-MY11. RESULTS: The prevalence of HPV was 6.8%, out of which 58.3% presented with cytopathologic alterations. And the presence of current cervical alterations can increase the chances of having HPV by almost 33 times (ORadj: 32.688; p < 0.001), recent vaginal infection increased the chances of HPV infection by 2.7 times (ORadj: 2.773; p = 0.04). The non-white ethnicity increased HPV infection chances threefold (ORadj: 3.058; p = 0.039). CONCLUSION: The main finding was low prevalence of HPV infection. Factors that may be linked to HPV infection were cervical alterations, recent vaginal infection, and women's ethnicity.

Syphilis, a sexually transmitted infection caused by the spirochete Treponema pallidum, has seen a resurgence over the past years. T. pallidum is capable of early dissemination and immune evasion, and the disease continues to be a global healthcare burden. The purpose of this study was to design a multi-epitope immunogen through an immunoinformatics-based approach. Multi-epitope immunogens constitute carefully selected epitopes belonging to conserved and essential bacterial proteins. Several physico-chemical characteristics, such as antigenicity, allergenicity, and stability, were determined. Further, molecular docking and dynamics simulations were performed, ensuring binding affinity and stability between the immunogen and TLR-2. An in silico cloning was performed using the pET-28a(+) vector and codon adaptation for E. coli. Finally, an in silico immune simulation was performed. The in silico predictions obtained in this work indicate that this construct would be capable of inducing the requisite immune response to elicit protection against T. pallidum. Through this methodology we have designed a promising potential vaccine candidate for syphilis, namely Tpme-VAC/LGCM-2022. However, it is necessary to validate these findings in in vitro and in vivo assays.
RESUMO
Resumen El linfogranuloma venéreo (LGV) es una infección de transmisión sexual (ITS) causada por Chlamydia trachomatis. En los últimos años, ha emergido principalmente en hombres que tienen sexo con hombres (HSH). Es frecuente su asociación con otras ITS como el virus de inmunodeficiencia humana (VIH) y la sífilis. Si bien el compromiso genital es la forma de presentación clásica, el síndrome anorrectal constituye el principal cuadro clínico en la actualidad. Presentamos el caso de un HSH con infección por VIH en terapia anti-retroviral, herpes genital recurrente y sífilis latente tratada, sin viajes recientes al extranjero, con adenopatías inguinales fistulizadas a piel, asociada a una úlcera genital dolorosa, sin síntomas anorrectales ni sistémicos, refractario a múltiples tratamientos antibacterianos y antivirales. El estudio con RPC de secreción de la fístula fue positiva a C. trachomatis. Se trató con doxiciclina por seis semanas, con buena respuesta clínica, sin complicaciones.
Abstract Lymphogranuloma venereum (LGV) is a sexually transmitted infection caused by Chlamydia trachomatis bacteria. In the past years, it has emerged as a relevant infectious agent, mainly affecting men who have sex with men (MSM), frequently associated with other sexually transmitted infections as human immunodeficiency virus (HIV) and syphilis. Even though genital lesions correspond to the classical presentation of LGV, nowadays anorectal syndrome is more frequently reported. We present a MSM patient, HIV infected, being treated with antiretroviral drugs, with a history of recurrent genital herpes, also recently treated for a syphilis in a latent stage. He had no recent trips. He referred inguinal fistulized enlarged lymph nodes, associated with a painful genital ulcer, he denied anorectal or systemic symptoms. He had been treated with multiple antibiotic and antiviral drugs, with no clinical response. Molecular studies from the content of the fistulized lymph node identified C. trachomatis. The patient received doxycycline for 6 weeks, showing good clinical response.

Resumen Neisseria meningitidis es una bacteria gramnegativa asociada frecuentemente a enfermedades invasoras de elevada mortalidad. Si bien su reservorio natural es la nasofaringe humana, en los últimos años han aumentado los aislamientos de este agente en la mucosa anorectal, principalmente en hombres que tienen sexo con hombres (HSH). Presentamos el caso de un HSH con infección por VIH, que consultó por un cuadro de uretritis y sifilis primaria, en el cual se aisló N. meningitidis en una muestra anorectal. Fue tratado en forma empírica con ceftriaxona y azitromicina, realizándose un cultivo de control post-tratamiento que fue negativo. A pesar del aumento de las infecciones y colonizaciones anogenitales por N. meningitidis, se desconoce su rol como patógeno genital, en la transmisión de otras infecciones y la necesidad de esquemas terapéuticos específicos.
Abstract Neisseria meningitidis is a Gram-negative bacterium frequently associated with invasive diseases with high mortality. Although its natural reservoir is the human nasopharynx, in recent years there have been increasing reports of isolation of this agent in the anorectal mucosa, mainly in men who have sex with men (MSM). We present the case of an HIV-positive MSM who consulted for urethritis and primary syphilis, in which N. meningitidis was isolated in an anorectal specimen. He was treated empirically with ceftriaxone and azithromycin, and a post-treatment control culture was negative. Despite the increase in anogenital infections and colonization by N. meningitidis, its role is unknown as a genital pathogen and in the transmission of other infections and the need for specific therapeutic regimens.

O adoecimento pode revelar impactos e consequências das desigualdades sociais, econômicas e culturais. Avaliar a soroprevalência da infecção pelo HIV, Hepatites B e C e Sífilis e o comportamento sexual dos moradores do Projeto de Assentamento Nova Amazônia (PANA). Trata-se de estudo observacional, transversal, descritivo, quantitativo e qualitativo, envolvendo 246 moradores do PANA, realizado entre novembro de 2019 e setembro de 2020. Foi aplicado um questionário e realizados testes rápidos para HIV 1 e 2, Sífilis e Hepatites B e C. Foi possível observar a prevalência de 4,1% para infecções sexualmente transmissíveis, estando associada estatisticamente com ser do gênero masculino (p = 0,04), ter mais de 40 anos (p = 0,003) e ter se relacionado com mais de 10 parceiros sexuais ao longo da vida (p = 0,03). Devido à identificação de condutas sexuais de risco, como baixíssima adesão ao uso do preservativo, faz-se necessária a realização de diagnóstico precoce e monitoramento de novos casos.
The illness can reveals impacts and consequences of social, economic and cultural inequalities. To evaluate the seroprevalence of HIV infection, Hepatitis B and C and Syphilis and sexual behavior of residents of the Nova Amazônia Settlement Project (PANA). Observational, cross-sectional, descriptive, quantitative and qualitative study, involving 246 residents of PANA, carried out between November 2019 and September 2020. A questionnaire was applied and rapid tests were performed for HIV 1 and 2, Syphilis and Hepatitis B and C. A prevalence of 4.1% for sexually transmitted diseases was observed, statistically associated with being male (p = 0.04), being over 40 years old (p = 0.003) and having been related with more than 10 sexual partners throughout life (p = 0.03). Due to the identification of risky sexual behaviors, such as very low adherence to condom use, it is necessary to perform an early diagnosis and monitor new cases.
RESUMO
Resumen INTRODUCCIÓN: Las úlceras de Lipschütz son una causa infrecuente de úlcera genital, de alivio espontáneo y casi siempre benignas, aunque en algunas pacientes pueden dejar cicatrices genitales. Lo común es que aparezcan en mujeres jóvenes, antes del inicio de la vida sexual activa, en coincidencia con un cuadro catarral o pseudogripal. CASO CLÍNICO: Paciente de 18 años con una úlcera vulvar dolorosa, coincidente con un episodio de amigdalitis aguda y fiebre de 38 ºC. La paciente negó haber tenido relaciones sexuales. La úlcera alcanzó 3 a 4 cm, profunda, purulenta, con apertura del labio menor derecho y con importante componente necrótico. Para el control del dolor se le indicaron: corticoides, doxiciclina oral, crema con lidocaína y antiinflamatorios. Los análisis de laboratorio descartaron que se tratara de infección de trasmisión sexual. Al término del esquema terapéutico prescrito la evolución fue favorable, con desaparición de los síntomas, pero con una secuela: apertura del labio mayor derecho. CONCLUSIONES: La úlcera de Lipschütz es una causa infrecuente de úlcera vulvar. Su tratamiento consiste en el control de los síntomas y casi siempre se cura en el transcurso de 4 a 6 semanas, sin dejar lesiones. El diagnóstico solo puede establecerse luego de excluir otras causas más frecuentes de úlcera vulvar.
Abstract INTRODUCTION: Lipschütz ulcers are an infrequent cause of genital ulcer, of spontaneous relief and almost always benign, although in some patients they may leave genital scars. They usually appear in young women, before the onset of active sexual life, coinciding with a catarrhal or flu-like condition. CLINICAL CASE: 18-year-old female patient with a painful vulvar ulcer, coinciding with an episode of acute tonsillitis and fever of 38 ºC. The patient denied having had sexual intercourse. The ulcer was 3 to 4 cm, deep, purulent, with opening of the right labium minora and with a significant necrotic component. For pain control she was prescribed corticosteroids, oral doxycycline, lidocaine cream and anti-inflammatory drugs. Laboratory tests ruled out sexually transmitted infection. At the end of the prescribed therapeutic scheme the evolution was favorable, with disappearance of symptoms, but with a sequel: opening of the right labium majus. CONCLUSIONS: Lipschütz ulcer is a rare cause of vulvar ulcer. Its treatment consists of symptom control and it almost always heals within 4 to 6 weeks, leaving no lesions. The diagnosis can only be established after other more frequent causes of vulvar ulceration have been excluded.
