RESUMO

ABSTRACT Waste pickers constitute a marginalized demographic engaged in the collection of refuse, facing considerable occupational hazards that heighten their susceptibility to contract infectious diseases. Moreover, waste pickers contend with societal stigmatization and encounter barriers to accessing healthcare services. To explore the viral profile of waste pickers potentially linked to their occupational environment, we conducted a metagenomic analysis on 120 plasma specimens sampled from individuals employed at the Cidade Estrutural dumpsite in Brasilia city, Brazil. In total, 60 blood donors served as a comparative control group. Specimens were pooled and subjected to Illumina NextSeq 2000 sequencing. Viral abundance among waste pickers revealed the presence of significant pathogens, including HIV, HCV, and Chikungunya, which were not detected in the control group. Additionally, elevated levels of anelloviruses and Human pegivirus-1 were noted, with a comparable incidence in the control group. These findings underscore the utility of metagenomics in identifying clinically relevant viral agents within underserved populations. The implications of this study extend to informing public health policies aimed at surveilling infectious diseases among individuals facing socioeconomic disparities and limited access to healthcare resources.

RESUMO

Abstract Monkeypox is an emerging infection that has spread to all continents since May 2022. It is caused by the zoonotic monkeypox virus, consisting of double-stranded DNA, belonging to the Orthopoxvirus genus of the Poxviridae family, which has high transmissibility, especially by contact with the skin, favoring its sexual transmission. This case report describes a same-sex male couple, both aged 28 years old, without comorbidities. In the index case, perioral and penile lesions started ten days before the consultation, with rapid progression and a high fever that started eight days after the appearance of the lesions. In the second case, the perioral lesions started three days after the partner; however, he remained afebrile. Both were isolated, treated with symptomatic measures, and, after ulceration, the lesions completely regressed in 14 days. Dermatologists should be aware of manifestations of monkeypox, which may include vesiculopustular lesions in areas of sexual contact, as well as oligosymptomatic cases or cases with few skin lesions.

RESUMO

Abstract In addition to the infestations and bacterial infections reported in part I, the study of entomodermoscopy also involves descriptions of dermoscopic findings of a growing number of viral and fungal infections, among others. In this article, the main clinical situations in viral infections where dermoscopy can be useful will be described, that is in the evaluation of viral warts, molluscum contagiosum, and even in recent scenarios such as the COVID-19 pandemic. As for fungal infections, dermoscopy is particularly important, not only in the evaluation of the skin surface, but also of skin annexes, such as hairs and nails. The differential diagnosis with skin tumors, especially melanomas, can be facilitated by dermoscopy, especially in the evaluation of cases of verruca plantaris, onychomycosis and tinea nigra.

RESUMO

Abstract Anogenital warts are a worldwide public health problem. They consist of epithelial proliferations caused by HPV, whose transmission occurs mainly through sexual intercourse. In this study, we evaluated their impact on the quality of life of adult males. We interviewed 88 men in an outpatient clinic for sexually transmitted diseases at a Brazilian public institution, using the DLQI-BRA questionnaire. Most patients (81%) presented mild or no impairment of quality of life. The main dimensions affected were sex life, symptoms, and embarrassment. The low impact on quality of life may well justify the delay in seeking medical treatment, favoring the spread of the disease.

RESUMO

JUSTIFICATIVA E OBJETIVOS: O herpes zoster tem como principal complicação a neuralgia pós-herpética (NPH). Utiliza-se para o tratamento a carbamazepina (CXB), um anticonvulsivante bem tolerado, porém frequentemente associado a reações Cutâneas graves, como, por exemplo, a síndrome de Stevens-Johnson (SSJ) e a necrólise epidérmica tóxica (NET). O objetivo deste trabalho é relatar um caso de SSJ/NET secundário ao uso de CBZ em paciente com NPH. RELATO DO CASO: Paciente do sexo feminino, com dor contínua em região torácica e dorso, intensa, em queimação, fisgada, choque, alteração de força de membro superior ipsilateral e sudorese. Apresentava lesões crostosas e eritematosas em região dorsal do tórax, com alodinia e disestesias em dermátomo acometido. Iniciou-se CBZ 300 mg.dia-1, amitriptilina (AMT) 12,5 mg à noite e infiltração com anestésico local na região afetada. Após 15 dias, referia mal-estar, febre, dores musculares e artralgias com rash cutâneo leve e inespecífico. Retirou-se a carbamazepina imediatamente. Uma semana depois, foi internada com urticária e exantema generalizados, erupções Cutâneas eritematosas, bolhosas e máculas purpúricas por todo o corpo. A impressão era de SSJ/NET induzida por carbamazepina. Houve progressiva piora do quadro, com aumento do número e do tamanho das lesões Cutâneas, além de rash eritematoso macular generalizado, áreas de necrose e erosões, com destacamento simétrico da epiderme em face, pescoço, tórax, dorso e membros acometendo mais de 50 por cento da área de superfície, além de envolvimento da mucosa bucal, conjuntival e genital com erosões vesiculares. Apresentou piora funcional progressiva, evoluindo com choque séptico e falência múltipla de órgãos, indo a óbito. CONCLUSÕES: A SSJ/NET é uma reação Cutânea grave com potencial para morbidade e mortalidade elevadas e que demanda intervenção rápida e tratamento adequado. Fica também o alerta para o uso da carbamazepina, que deve sempre ser supervisionado, ...

BACKGROUND AND OBJECTIVES: Post-herpetic neuralgia (PHN) is the main complication of herpes zoster. Carbamazepine (CBZ), a well-tolerated anticonvulsant, but frequently associated with severe cutaneous reactions, such as the Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) is used in the treatment of this complication. The objective of this article was to report a case of SJS/TEN secondary to CBZ in a patient with PHN. CASE REPORT: This is a female patient with continuous severe, burning, chock-like pain in the thoracic region and dorsum associated with reduced strength in the ipsilateral upper limb and diaphoresis. She had crusty and erythematous lesions in the dorsal region of the thorax with allodynia and dysesthesia in the affected dermatome. She was treated with CBZ 300 mg.day-1, amitriptyline (AMT) 12.5 mg at bedtime, and infiltration with local anesthetic in the affected region. After 15 days, she developed malaise, fever, muscle pain, and arthralgia with a mild non-specific cutaneous rash. Carbamazepine was discontinued immediately. One week later, she was hospitalized with urticaria, generalized exanthema, erythematous cutaneous eruptions, bullae, and purpuric maculae all over her body. The impression was of carbamazepine-induced SJS/TEN. She evolved with progressive worsening of her symptoms, with increase in the number and size of cutaneous lesions, besides generalized erythematous macular rash, areas of necrosis, and erosions with symmetrical loosening of the epidermis in face, neck, thorax, dorsum, and limbs, affecting more that 50 percent of her body surface, besides involvement of buccal, conjunctival, and genital mucosa with vesicular erosions. She had progressive functional worsening, evolving to septic shock and multiple organ failure followed by death. CONCLUSIONS: Stevens-Johnson syndrome and toxic epidermal necrolysis are severe cutaneous reaction with potential for elevated morbidity and mortality ...

El objetivo de este trabajo es relatar un caso de SSJ/NET secundario al uso de CBZ en paciente con NPH. RELATO DEL CASO: Paciente del sexo femenino, con dolor continuo e intenso en la región torácica y dorso, ardor, punzada, descarga eléctrica, alteración de fuerza del miembro superior ipsilateral y sudoración. Presentaba lesiones de postillas y eritemas en la región dorsal del tórax, con alodinia y disestesias en el dermatoma acometido. Se inició CBZ 300 mg.día-1, amitriptilina (AMT)12,5 mg por la noche e infiltración con anestésico local en la región afectada. Después de 15 días, el paciente decía sentir un fuerte malestar, fiebre, dolores musculares y artralgias con rash cutáneo ligero e inespecífico. Se le retiró la carbamazepina inmediatamente. Una semana después fue ingresado con urticaria y exantema generalizados, erupciones cutáneas eritematosas, burbujas y marcas purpúricas por todo el cuerpo. La impresión era de SSJ/NET inducida por carbamazepina. Hubo un progresivo empeoramiento del cuadro, con aumento del número y del tamaño de las lesiones cutáneas, además de rash eritematoso macular generalizado, áreas de necrosis y erosiones simétricas de la epidermis en la cara, cuello, tórax, dorso y miembros, llegando a más del 50 por ciento del área de superficie, además de la involucración de la mucosa bucal, conjuntival y genital con erosiones vesiculares. Presentó un empeoramiento funcional progresivo, evolucionando con choque séptico y fracaso multiorgánico, lo que produjo finalmente su deceso. CONCLUSIONES: La SSJ/NET es una reacción cutánea grave con potencial para la ...
