Monkeypox: What the Dermatologist Needs to Know.

Monkeypox, an endemic disease in some African countries, has provoked public health activeness on a global scale that even the World Health Organization (WHO), invoking international health regulations, declared it a public health emergency of international concern (PHEIC). The WHO called attention of member states to exert maximum surveillance over the disease, its patients, and contact persons in order to standardize control measures. A need was directed to provide complete knowledge about the disease, allowing the administration of prior diagnoses as well as isolation and more effective epidemiologic control measures. An updated review on monkeypox emphasized upon having the fundamental aspects of the lesions caused by the disease, and appropriate management of patients upon clinical and epidemiologic evaluation.

Heparin-Induced Bullous Hemorrhagic Dermatosis: A Report of an Exceptionally Exuberant Case and Literature Review.

INTRODUCTION: Heparin-induced bullous hemorrhagic dermatosis (HBHD) is an unusual cutaneous adverse reaction to heparin characterized by acute onset of hemorrhagic bullae. METHODOLOGY: An exuberant case of HBHD is reported, and a revision of previously reported cases indexed on PubMed is provided. Cases were tabulated to the following parameters: sex, age, type of heparin and route of administration, associated medical procedure, number of days between heparin start and onset of lesions, site of the lesions, level of blister on histopathology, inflammatory infiltrate on histopathology, direct immunofluorescence findings, heparin-related intervention, number of days to resolution of skin lesions, associated hemorrhagic event, and outcome. CASE REPORT: A 21-year-old woman with end-stage renal disease was receiving intravenous unfractioned heparin (UFH) during hemodialysis section for the past 3 months. Four hours after using for the first time an arteriovenous fistula punctured on her right wrist, the patient noticed the onset of vesicles and blisters on the right forearm containing citrus or serohemorrhagic exudate, which became overt hemorrhagic in 24 hours. Histopathology depicted a nonacantholytic subcorneal blister containing erythrocytes and plasma without any significant dermal inflammatory infiltrate. RESULTS: Sixty cases of HBHD were included. HBHD affected predominantly men, with a male/female rate of 2.75. The age range was from 21 to 94 years, with an average of 70.8 and a median of 72 years. Nine patients used UFH, and 54 patients used low molecular weight heparins (3 patients used both). The lapse of time between the start of heparin and the onset of skin lesion varied from 6 hours to 240 days, with an average of 17.3 days and a median of 7 days. Limbs were affected in most of the cases. The level of the blister was subcorneal in 10 patients, intraepidermal in 30, subepidermal in 8, and both intraepidermal and subepidermal in 1. In 33 cases, there was no significant dermal inflammatory infiltrate. Pure lymphocytic inflammatory infiltrate was present in 10 cases. Eosinophils were found within the dermal inflammatory infiltrate in 2 cases, neutrophils in 2, and a mixture of eosinophils and neutrophils in other 2. Direct immunofluorescence was performed in 18 cases, all of them with negative results. DISCUSSION: We hypothesize that mechanical trauma, skin fragility, and the anticoagulation effect of heparin might contribute concomitantly to the development of the lesions and speculate that subepidermal blisters in HBHD could be formed by rupture of the floor of a former intraepidermal blister.

Adverse effects of polychemotherapy for leprosy in 13 years of follow-up at a university hospital

Abstract Leprosy is one of the neglected diseases in the world and Brazil is the second country with more cases. A retrospective study was conducted based on the medical records of 196 leprosy patients diagnosed during the course of 13 years at a university hospital. The aim was to describe the adverse effects of polychemotherapy, as well the most prevalent and most vulnerable populations. In the study, dapsone was the most implicated drug, especially in women, and the risk increased with age. The authors conclude that with this patient profile, greater vigilance should be taken regarding possible adverse effects, especially anemia.

Erythema Nodosum Leprosum: Update and challenges on the treatment of a neglected condition.

Erythema Nodosum Leprosum (ENL) occurs due to the immunological complication of multibacillary leprosy and is characterized by painful nodules and systemic compromising. It is usually recurrent and/or chronic and has both physical and economic impact on the patient, being a very important cause of disability. In addition, ENL is a major health problem in countries where leprosy is endemic. Therefore, adequate control of this condition is important. The management of ENL aims to control acute inflammation and neuritis and prevent the onset of new episodes. However, all currently available treatment modalities have one or two drawbacks and are not effective for all patients. Corticosteroid is the anti-inflammatory of choice in ENL but may cause dependence, especially for chronic patients. Thalidomide has a rapid action but its use is limited due the teratogenicity and neurotoxicity. Clofazimine and pentoxifylline have slow action and have important adverse effects. Finally, there is no pattern or guidelines for treating these patients, becoming more difficult to evaluate and to control this condition. This review aims to show the main drugs used in the treatment of ENL and the challenges in the management of the reaction.

Type 2 leprosy reaction with Sweet's syndrome-like presentation.

Leprosy is a chronic disease characterized by manifestations in the peripheral nerves and skin. The course of the disease may be interrupted by acute phenomena called reactions. This article reports a peculiar case of type 2 leprosy reaction with Sweet's syndrome-like features as the first clinical manifestation of leprosy, resulting in a delay in the diagnosis due to unusual clinical presentation. The patient had clinical and histopathological features reminiscent of Sweet's syndrome associated with clusters of vacuolated histiocytes containing acid-fast bacilli isolated or forming globi. Herein, it is discussed how to recognize type 2 leprosy reaction with Sweet's syndrome features, the differential diagnosis with type 1 leprosy reaction and the treatment options. When this kind of reaction is the first clinical presentation of leprosy, the correct diagnosis might be not suspected clinically, and established only with histopathologic evaluation.

Cutaneous involvement by cytomegalovirus in a renal transplant recipient as an indicator of severe systemic infection.

Cytomegalovirus is an opportunistic virus that commonly affects immunosuppressed patients. Cutaneous involvement by this virus is rare and occurs in significantly immunocompromised hosts, with a poor prognosis. Skin ulcers may represent the first sign of systemic infection by cytomegalovirus in these patients. Herein, a case of a systemic infection by Cytomegalovirus presenting as genital and oral ulcers in a kidney-transplant recipient is reported.

Do you know this syndrome? / Voce conhece esta sindrome?

Berardinelli-Seip syndrome is a rare autosomal recessive disease characterized by inadequate metabolism and inefficient storing of lipids in fat cells, generating accumulation of fat in organs such as the liver, spleen, pancreas, heart, arterial endothelium and skin. Classically, patients manifest generalized lipoatrophy at birth or until 2 years of age, and in adolescence usually develop marked insulin resistance with rapid progression to diabetes and dyslipidemia. We report the case of a 17-year-old Berardinelli-Seip syndrome patient with eruptive xanthoma associated with severe hypertriglyceridemia. It is worth noting Eruptive xanthoma as a dermatological manifestation that is not generally highlighted in the reports of cases of this genetic metabolic disorder.

Síndrome de Berardinelli-Seip é doença genética autossômica recessiva rara, caracterizada por ineficiência em metabolizar e estocar material lipídico adequadamente nos adipócitos, gerando acúmulo de gordura em órgãos não habituais, como fígado, baço, pâncreas, coração, endotélio arterial e pele. Classicamente, os portadores nascem ou manifestam lipoatrofia generalizada até os 2 anos e, geralmente na adolescência, desenvolvem marcada resistência insulínica com rápida progressão para diabetes e dislipidemia. Relatamos um caso de portadora da síndrome de Berardinelli-Seip, de 17 anos, com xantoma eruptivo associado à hipertrigliceridemia grave. Ressalta-se o xantoma eruptivo como manifestação dermatológica não enfatizada nos casos relatados sobre esse distúrbio metabólico genético.

Educação em saúde e busca ativa de casos de hanseníase em uma escola pública em Ananindeua, Pará, Brasil / Health education and active search for cases of leprosy in a public school in Ananindeua, Pará, Brazil / Educación para la salud y búsqueda activa de casos de lepra en una escuela pública en Ananindeua, Pará, Brasil

Objetivo: Descrever ação para o controle da hanseníase por meio da educação em saúde e da busca ativa de casos na faixa etária escolar, em uma instituição pública de ensino do município de Ananindeua, Pará. Métodos: Trata-se de estudo descritivo, conduzido em uma instituição pública de ensino, incluindo estudantes do ensino fundamental. Em outubro e novembro de 2010 foram realizadas palestras na escola sobre hanseníase e outras dermatoses e, em seguida, foi feita uma triagem com os alunos que apresentaram alguma mancha na pele. No total de 532 alunos envolvidos, foram identificados 55 alunos como casos suspeitos para hanseníase. Esses alunos foram conduzidos para consulta dermatológica, sendo realizados o exame clínico e a aplicação de questionários sociodemográficos. Resultados: A face (49%) e os membros superiores (45%) foram as principais regiões do corpo com lesões. Na maioria dos casos investigados tratava-se de pitiríase alba (42%) e pitiríase versicolor (31%). Entretanto, diagnosticou-se um caso de hanseníase (2%), na forma clínica tuberculóide. Conclusão: Considerando a abrangência do estudo, o número de casos de hanseníase encontrado é significativo e reafirma a alta taxa de detecção de hanseníase em menores de 15 anos no município. Ações de vigilância epidemiológica devem ser intensificadas, no sentido de detectar a doença mais precocemente, contribuindo para a redução de estigmas e da restrição à participação social.

Objectives: To describe action for leprosy control through health education and case active search among school age children in a public school in the municipality of Ananindeua, Pará state. Methods: This is a descriptive study conducted in a public school including elementary school students. In October and November 2010, lectures on leprosy and other skin lesions were given in this school and then screening was performed with students that presented skin spots. From the total of 532 students involved, 55 were identified as suspected to leprosy. These students were taken to dermatological appointment including clinical examination and application of socio-demographic questionnaire. Results: The face (49%) and upper limbs (45%) were the main body areas presenting lesions. In most of the cases investigated, pityriasis alba (42%) and pityriasis versicolor (31%) were diagnosed. However, one case of leprosy (2%) was also found, in tuberculoid clinical form. Conclusion: Considering the scope of the study, the number of leprosy cases found is significant and confirms the high detection rate of leprosy in children under age 15 in the city. Epidemiological surveillance actions should be intensified in order to detect the disease in its early stage, contributing to enhancement in social participation by reducing the disease-related stigma.

Hanseníase em menores de 15 anos: a importância do exame de contato / Leprosy in children under 15 years: the importance of early diagnosis / Enfermedad de Hansen en menores de 15 años: la importancia del examen de contacto

Descrever dois casos de hanseníase em menores de 15 anos, sendo um de paciente com 18 meses de idade e outro de 13 anos, diagnosticados por modos de detecção diferentes, ressaltando a importância de examinar os contatos. DESCRIÇÃO DO CASO: Um dos casos foi diagnosticado precocemente por meio do exame de contatos intradomiciliares, enquanto o outro foi diagnosticado por demanda espontânea após quatro anos de aparecimento das lesões e, apesar de ser contato de um ex-paciente, não foi examinado na época. COMENTÁRIOS: Em países endêmicos, a alta detecção da hanseníase em menores de 15 anos revela a persistência na transmissão do bacilo e as dificuldades dos programas de saúde para o controle da doença. O maior tempo para diagnóstico ocasiona sequelas e deformidades e, dessa forma, a busca dos contatos constitui importante método para o diagnóstico precoce da doença na infância, quando os sinais clínicos nem sempre são fáceis de serem identificados e há grande diversidade de formas clínicas em que a doença pode se apresentar.

To describe two cases of leprosy in children under 15 years old, being one patient aged with 18 months and other 13 years, diagnosed by different modes of detection, emphasizing the importance of examining the contacts. CASE DESCRIPTION: One of the cases was diagnosed early by examining household contacts, while the other was diagnosed by spontaneous demand, after four years of the onset of lesions, although he had been a former patient contact who was not examined at the time. COMMENTS: In endemic countries, the high detection of leprosy in children under 15 years old reveals the persistence of the bacillus transmission and the difficulties encountered by public health programs to control the disease. Delay in leprosy diagnosis leads to sequels and deformities and, thus, the search for contacts is important as an effective method for early diagnosis of the disease in childhood, where clinical signs are not always easy to be identified due to the great variety of clinical forms in which the disease may occur.

Report of three new leprosy cases in children under fifteen in the municipality of Itaguai, Rio de Janeiro: event alert for epidemiological investigation.

Leprosy is an infectious disease with an average incubation period of two to five years. It is caused by Mycobacterium leprae, mainly affecting skin, mucous membranes and peripheral nerves. When it occurs in children under fifteen, it reflects an intense and long contact period, with a high bacillary load. Therefore, it is considered an important alert sign that points to the challenge of controlling the disease. The authors report three cases of leprosy in children under fifteen that occurred in the Itaguaí district, Rio de Janeiro. The epidemiologic implications of new cases detected at this age and the fundamental role of examining the patients' close contacts and the possible identification of source cases as an effort for leprosy control are discussed.

A hanseníase é uma doença infectocontagiosa, com período de incubação médio de dois a cinco anos, causada pelo Mycobacterium leprae, o qual possui tropismo para a pele, as mucosas e os nervos periféricos. Quando manifestada em crianças abaixo de quinze anos, reflete a intensidade e longo período de exposição à grande carga bacilar. Representa, então, um importante evento de alerta que aponta para uma dificuldade no controle da doença. Os autores relatam três casos de hanseníase, em menores de quinze anos, provenientes do Município de Itaguaí, Rio de Janeiro. Discutem-se as implicações epidemiológicas da detecção de novos casos nessa faixa etária e o papel fundamental do exame de contatos e da busca do caso fonte no controle da Hanseníase.

Dermatomyofibroma: a case report of a rare disease.

Dermato myofibroma is included in the group of benign cutaneous mesenchymal neoplastic lesions of fibroblastic and myofibroblastic lineage. It's a rare disease and there are approximately only one hundred cases described worldwide in the medical literature up to now. The present study reports the case of a young woman with typical clinical cutaneous lesion and histopathological diagnosis of dermato myofibroma. Special stains were carried out which showed preserved collagen fibers and immunohistochemistry was positive for vimentin and negative for actin and S100. As it is a rare disease, the histopathological findings are of great importance but clinical suspicion is possible in typical cases such as this one.

Dermatomiofibroma: relato de caso de doença rara / Dermatomyofibroma: a case report of a rare disease

O Dermatomiofibroma está incluído no grupo de lesões neoplásicas mesenquimais benignas de linhagem fibroblástica e miofibroblástica da pele. É uma doença rara, havendo aproximadamente 100 casos descritos na literatura mundial até o momento. Este artigo relata o caso de uma mulher jovem com apresentação clínica típica e diagnóstico histopatológico de dermatomiofibroma. Foram realizadas colorações especiais que mostraram preservação das fibras colágenas e a imunohistoquímica revelou positividade para vimentina e negatividade para actina e S100. Por se tratar de doença rara, os achados histopatológicos são de grande importância, mas a supeição clínica é possível em casos típicos como este.

Trombose venosa profunda em um paciente com reação hansênica em uso de talidomida e corticóide: um raro efeito adverso? / Deep vein thrombosis in a patient with leprosy reaction in use of thalidomide and corticosteroids: a rare adverse effect?

Após re-introdução no mercado, a Talidomida tornou-se a droga mais eficaz no tratamento do eritema nodoso hânsenico, além de opção terapêutica para diversas doenças, como mieloma múltiplo. Contudo, o crescente uso desta, associado a corticóides sistêmicos e quimioterápicos, resultou em aumento de efeitos adversos pouco reconhecidos, como trombose venosa profunda.

After being reintroduced in the market, thalidomide has become the most effective drug in the treatment of erythema nodosum leprosum and a therapeutic option for several diseases, such as multiple myeloma. However, its increasing use, combined with systemic steroids and chemotherapy has also increased little recognized adverse effects, such as deep vein thrombosis.
