Abstract: Lichen planopilaris is a disease that appears with lymphocytic cicatricial alopecia. It is considered a follicular variant of lichen planus. The examination of affected areas shows alopecia with perifollicular erythema and scaling, revealing a predilection for hair follicles. The involvement of children is uncommon, with few reports in this population in the literature. This study presents a clinical case of a male patient of 15 years of age with characteristic lesions of lichen planopilaris.

Abstract:Afro-ethnic hair is different from Caucasian and Asian hair and has unique features. Ethnic hair is more prone to certain conditions or diseases. Such diseases are not only related to the fragile inner structure of the hair, but also to the cultural habits of hairstyles that often exert traction forces upon the pilosebaceous follicle. Women with African hair subject their hair to chemical treatments such as hair straightening and relaxing, and thus modify the structure of their hair shaft, making it more susceptible to damage. For this reason, hair complaints are common among black women and represent a diagnostic challenge to the dermatologist, requiring a thorough clinical examination of the hair and scalp, and a detailed medical history of the patient. The purpose of this review is to warn of the potential side effects and sequelae related to hairstyles and hair treatments used by black women, and to highlight the major diseases that affect this ethnicity.

Abstract Drug-induced lupus is a rare drug reaction featuring the same symptoms as idiopathic lupus erythematosus. Recently, with the introduction of new medicines in clinical practice, an increase in the number of illness-triggering implicated drugs has been reported, with special emphasis on anti-TNF-α drugs. In the up-to-date list, almost one hundred medications have been associated with the occurrence of drug-induced lupus. The authors present two case reports of the illness induced respectively by hydralazine and infliximab, addressing the clinical and laboratorial characteristics, diagnosis, and treatment.

Tuberculosis continues to draw special attention from health care professionals and society in general. Cutaneous tuberculosis is an infection caused by M. tuberculosis complex, M. bovis and bacillus Calmette-Guérin. Depending on individual immunity, environmental factors and the type of inoculum, it may present varied clinical and evolutionary aspects. Patients with HIV and those using immunobiological drugs are more prone to infection, which is a great concern in centers where the disease is considered endemic. This paper aims to review the current situation of cutaneous tuberculosis in light of this new scenario, highlighting the emergence of new and more specific methods of diagnosis, and the molecular and cellular mechanisms that regulate the parasite-host interaction.

As infecções fúngicas superficiais dos cabelos, pele e unhas representam uma causa importante de morbidade no mundo. O tratamento nem sempre é simples, havendo dificuldade na escolha dos esquemas terapêuticos disponíveis na literatura, assim como suas possíveis interações medicamentosas e efeitos colaterais. A segunda parte do trabalho aborda os principais esquemas terapêuticos das micoses superficiais - ceratofitoses, dermatofitoses, candidíase -, possibilitando a consulta prática das drogas tópicas e sistêmicas mais utilizadas, sua dosagem e tempo de utilização. Novas possibilidades terapêuticas antifúngicas também são ressaltadas, assim como as apresentações disponíveis no mercado brasileiro e mundial.

Superficial fungal infections of the hair, skin and nails are a major cause of morbidity in the world. Choosing the right treatment is not always simple because of the possibility of drug interactions and side effects. The first part of the article discusses the main treatments for superficial mycoses - keratophytoses, dermatophytosis, candidiasis, with a practical approach to the most commonly-used topical and systemic drugs , referring also to their dosage and duration of use. Promising new, antifungal therapeutic alternatives are also highlighted, as well as available options on the Brazilian and world markets.

As doenças sexualmente transmissíveis (DSTs) apresentam prevalência significativa tanto na população geral quanto nas gestantes. Nestas, em especial, devem-se considerar as alterações fisiológicas em seu organismo que podem, inclusive, alterar o curso dessas doenças. Complicações obstétricas e neonatais podem ocorrer em decorrência delas, acarretando aumento da morbimortalidade materno-infantil. Abordam-se, neste artigo, as particularidades da história natural e terapêutica no período gestacional das principais DSTs: cancro mole, donovanose, gonorreia, clamidíase, hepatites virais, herpes genital, infecção pelo papilomavírus humano (HPV), linfogranuloma venéreo, sífilis e vulvovaginites. As DSTs devem ser enfrentadas com extrema atenção e conscientização por parte dos profissionais de saúde, principalmente, no tocante ao diagnóstico, que deve ser o mais precoce possível, e ao tratamento, que apresenta limitações na terapêutica durante a gestação, pela toxicidade de muitos dos medicamentos comumente empregados. A prevenção e o tratamento do parceiro são importantes para que as ações sejam efetivas.

Sexually transmitted diseases (STDs) have a significant prevalence in both the general population and pregnant women. Accordingly, we consider the physiological changes of the maternal organism that can alter the clinical course of these diseases. In addition, obstetric and neonatal complications may occur, resulting in increased maternal and infant morbidity and mortality. We explore features of the natural course and treatment during pregnancy of the major STDs: soft chancre, donovanosis, gonorrhea, chlamydia, viral hepatitis, genital herpes, human papillomavirus (HPV) infection, lymphogranuloma venereum, syphilis, and vulvovaginitis. We believe that health professionals should pay careful attention to STDs, particularly in relation to early diagnosis and precautions on the use of drugs during pregnancy. Prevention and partner treatment to achieve effective results are also extremely relevant.
