Bilateral uveitis in silent ulcerative colitis: case report

Silent or subclinical inflammatory bowel diseases (IBD) is a relatively new term that has been used to describe individuals with asymptomatic active mucosal bowel inflammation, often unaware of their disease due to either the lack of or mild inflammatory symptoms. These patients are at risk for gastrointestinal and extra-gastrointestinal manifestations, with more advanced complications. In this article we intend to describe a case report of a patient with chronic history of many organ involvements including ocular, skin, and musculoskeletal, which was later placed under the umbrella of silent ulcerative colitis.

ABSTRACT Objective: to identify the locoregional adverse effects of administering intravenous oncologic therapy in women with advanced breast cancer. Method: this was an integrative literature review using the PubMed/MEDLINE, CINAHL, LILACS, and EMBASE databases, without a time cut, in addition to a reverse search of the selected articles updated until May 2022. The population included women with advanced breast cancer undergoing intervention with intravenous oncologic therapy with chemotherapy, hormone therapy, or monoclonal antibody, and the outcome assessed locoregional adverse effects. Results: 2,789 studies were identified, and the final sample consisted of 8 clinical trials and 1 retrospective observational study, all of which were international studies published from 1986 to 2018. Predominantly, patients with stage IV breast cancer, were aged 50 years or older, and had multiple metastases. Locoregional adverse effects were phlebitis, ulceration and/or necrosis, pain, erythema, and unspecified injection site reaction. The studies did not detail the type of venous catheter, the osmolarity of the drugs, and preventive care to reduce these adverse effects. Conclusion: the evidence from these articles showed that locoregional adverse effects are present in efficacy research of oncologic drugs in women with advanced breast cancer. Nonetheless, the safety of administering cancer drugs is not elucidated in this review, indicating the need for follow-up studies of adverse effects.

Screening complications in the postoperative period of orthopedic surgeries by video arthroscopy

To analyze the prevalence and characteristics of late postoperative complications of orthopedic surgeries by video arthroscopy.This was a descriptive cross-sectional study that evaluated, through its own instrument, local and systemic postoperative complications of patients undergoing orthopedic surgeries by video arthroscopy. The study included 270 patients, who were evaluated on days 30(without prosthesis) and 90(with prosthesis placement) of the postoperative period, by telephone service. The selection of participants occurred sequentially and population-based, within the data collection period, from February to July 2020, in a large hospital for medium and high complexity surgeries. Of the 270 procedures performed in the period, 4.4% (n = 12) presented late postoperative infection. The most frequent complications were erythema (83%), edema (75%) and secretion (67%) in the surgical wound. Most used antibiotic therapy (92%) and anti-inflammatory drugs (67%). Hospital readmission was not necessary concerning the complications. Only 50% required medical evaluation before the scheduled time.The need for practices that ensure the quality of perioperative care and improve the active search to assess surgical outcomes is reinforced.

Enfermedad invasiva por Streptococcus pyogenes con celulitis de manos bilateral: A propósito de un caso / Invasive Streptococcus pyogenes disease with bilateral cellulitis of the hands: A case report

El Streptococcus pyogenes o estreptococo B hemolítico Grupo A (EßHGA) suele ser una causa poco habitual de enfermedad invasiva en pediatría, la cual ha presentado un aumento en su incidencia en los últimos años. Se define como cualquier infección asociada al aislamiento de dicha bacteria de un sitio normalmente estéril y cuya presentación más frecuente es la bacteriemia. Los pacientes con EßHGA habitualmente se presentan con un sindrome febril asociado a manifestaciones clínicas relacionadas con el sitio primario de infección. Se presenta el caso de una paciente de 10 años, sin comorbilidades, que desarrolló enfermedad invasiva por EßHGA con bacteriemia e impacto secundario de piel y partes blandas resultando en una celulitis de manos bilateral

Streptococcus pyogenes or Group A Streptococcus (GAS) is an infrequent cause of invasive disease in pediatrics. Its incidence has increased in the last few years. It is defined as any infection associated with the isolation of GAS in a normally sterile site and its most frequent presentation is bacteremia. Patients with GAS bacteremia usually present with a febrile syndrome associated with clinical manifestations related to the primary site of infection. We present the case of a previously healthy, 10-year-old patient, who developed an invasive disease due to GAS with bacteremia and secondary impact of skin and soft tissues that developed in bilateral cellulitis of the hands

Usefulness of dermoscopy in the evaluation of patch test reactions

Abstract Background: Despite being widely used in different areas of dermatology, there have been few studies evaluating the benefit of dermoscopy in the interpretation of patch tests, especially in weak and doubtful reactions. Objectives: To evaluate the role of dermoscopy in the interpretation of patch tests and describe the main findings of the reactions. Method: Prospective study, carried out in dermatology reference centers in southern Brazil, which evaluated the final results of patch tests analyzed with the aid of dermoscopy. Results: 77 patients and 160 reactions were included. The most prevalent substances were nickel sulphate (23.8%), kathon CG (9.4%), and perfume mix (8.8%). The main dermoscopic findings were reaction area greater than half of the chamber site (90%), homogeneous erythema (86.9%), vesicles (30%), crusts (21.3%), perifollicular erythema (35%), pore reaction (19.4%) and pustules (8.8%). Dermoscopy was found to facilitate the definition of erythema in reactions on black skin and when due to substances with deposition of pigment. Of the 64 weak or doubtful reactions, 36 (56.25%) showed a change in the final result after dermoscopy evaluation; of the 36 doubtful reactions, 33 (91.6%) showed a change in the final result after dermoscopy evaluation (p < 0.001). Study limitations: The probable limitation of the study is its sample size. Though certain significance levels have been reached, other possible relationships may not have been observed. Conclusion: Dermoscopy improves significantly the interpretation of patch tests, especially in weak and doubtful reactions.

Reativação da BCG após vacina contra COVID-19: relato de caso / BCG reactivation after COVID-19 vaccine: case report

A reativação da BCG pode ocorrer em diversos contextos: associada a quadros infecciosos, imunossupressão, autoimunidade e pós-vacinações. Além disso, especialmente em crianças abaixo de 5 anos de idade, deve ser valorizada como um achando presente em cerca de 50% dos casos de Doença de Kawasaki. Neste artigo, relatamos o primeiro caso publicado na literatura de uma paciente adulta jovem, a qual manifestou uma reativação de BCG após receber a primeira dose de vacina contra COVID-19 (AztraZeneca/Oxford/Biomanguinhos). Dentro das primeiras 24h após a administração da vacina, a paciente desenvolveu febre alta, sudorese, dor local, mialgia difusa e cefaleia. Após dois dias, iniciou eritema e enduração no local da cicatriz da vacina BCG. Ela tem como comorbidade a urticária crônica espontânea, porém estava assintomática sem crises há mais de 1 ano. Tem como antecedente familiar relevante o óbito materno por síndrome complexa de sobreposição de autoimunidade (lúpus eritematoso sistêmico, síndrome de Sjögren e síndrome do anticorpo antifosfolípide). Após ser medicada com anti-inflamatórios não esteroides (AINE) e corticoterapia tópica de moderada potência por 3 dias, houve resolução completa da reativação da BCG. A paciente, após 3 meses, recebeu a segunda dose da vacina e não manifestou nenhum sintoma. Acredita-se que a reativação da BCG ocorra devido a um mecanismo de reação cruzada entre HSP do indivíduo, elicitadas como mediadores da imunidade inata frente à inflamação vacinal, com alguns epítopos do M. bovis. Recomendase que seja investigada alguma condição imunossupressora ou autoimune nos pacientes que manifestem reativação da BCG, principalmente em adultos, na qual a doença de Kawasaki é bastante rara. As vacinas, incluindo as contra COVID-19, também podem desencadear o surgimento deste fenômeno imunológico ainda pouco compreendido.

BCG reactivation can occur in different contexts: associated with infectious conditions, immunosuppression, autoimmunity and post-vaccinations. Also, especially in children below of 5 years of age, should be valued as a finding present in about 50% of cases of Kawasaki disease. In this article, we report the first case published in the literature of a young adult patient, who manifested a reactivation of BCG after receiving the first dose of vaccine against COVID-19 (AztraZeneca/Oxford/Biomanguinhos). Within the first 24 hours after the administration of the vaccine, the patient developed high fever, sweating, local pain, diffuse myalgia and headache. After 2 days, erythema and induration at the site of the BCG vaccine scar began. she has how comorbidity to chronic spontaneous urticaria, but she was asymptomatic without crises for more than 1 year. The relevant family history is maternal death due to the complex syndrome of autoimmunity overlap (systemic lupus erythematosus, Sjögrens syndrome, and anti-phospholipid antibody). After being medicated with NSAID and moderate topical corticosteroid therapy potency for 3 days, there was complete resolution of BCG reactivation. The patient, after 3 months, received the 2nd dose of the vaccine and had no symptoms. It is believed that the reactivation of BCG occurs due to a cross-reaction mechanism between the individuals HSP, elicited as mediators of innate immunity against vaccine inflammation, with some epitopes of M. bovis. It is recommended that any immunosuppressive or autoimmune condition be investigated in patients that manifest BCG reactivation, especially in adults, in which Kawasaki disease is quite rare. Vaccines, including those against COVID-19, can also trigger of this immunological phenomenon still poorly understood.

Fixed pigmented erythema to secnidazole / Eritema pigmentar fixo à secnidazol

Rare description of drug fixed eruption induced by secnidazole.

Descrição rara de eritema pigmentar fixo induzido por secnidazol.

Erupção pigmentar fixa à nimesulida comprovada por teste de contato / Fixed pigmented erythema from nimesulide proven by patch testing

A erupção pigmentar fixa (EPF) é uma reação cutânea adversa a drogas relativamente comum, envolvendo cerca de 10% de todas as reações de hipersensibilidade a medicamentos (RHM). Envolve uma reação imunológica não imediata, mediada por células T CD8+ sensibilizadas, relacionada ao mecanismo do tipo IVc na classificação de Gell e Coombs. Um dos grupos mais frequentemente implicados nesse tipo de reação é o dos antiinflamatórios. Relatamos o caso de um homem que, 24 horas após iniciar tratamento com nimesulida para lombalgia, apresentou um quadro de lesões cutâneas tipo máculas eritemato-violáceas bem delimitadas e disseminadas pelo corpo. A nimesulida é um fármaco anti-inflamatório não esteroidal (AINE) pertencente à classe das sulfonanilidas, que atua como inibidor seletivo da enzima da síntese de prostaglandina, a ciclo-oxigenase, inibindo preferencialmente a COX-2. O diagnóstico foi comprovado pela realização do teste de contato, também conhecido como patch test, que traduziu positividade na segunda leitura realizada após 72 horas da sua colocação.

Fixed pigmented erythema (FPE) is a relatively common adverse drug reaction, consisting of approximately 10% of all drug hypersensitivity reactions. It involves a non-immediate immune reaction mediated by sensitized CD8+ T cells and related to the type IVc mechanism in the Gell-Coombs classification. One of the groups most frequently involved in this type of reaction is that of anti-inflammatory drugs. We report the case of a man who, 24 hours after starting treatment with nimesulide for low back pain, presented with well-defined cutaneous lesions consisting of erythematous-violaceous macules and spread throughout the body. Nimesulide is a non-steroidal anti-inflammatory drug (NSAID) belonging to the sulfonanilide class that acts as a selective inhibitor of the prostaglandin synthesis enzyme, cyclooxygenase (COX), preferentially inhibiting COX-2. The diagnosis was confirmed by a patch test, which translated positively in the second reading performed 72 hours after its placement.

Atrofia branca de Milian / Atrofie blanche

A vasculopatia livedoide é uma doença cutâneo-vascular que surge devido à oclusão trombogênica de vasos da derme. Apresenta-se por meio de máculas ou pápulas eritematosas e purpúricas, em membros inferiores, que podem levar à ulceração dolorosa crônica e recorrente. Com a evolução, pode haver cicatrização, o que leva ao aparecimento de áreas de fibrose e cicatrizes atróficas, irregulares e esbranquiçadas, dando nome à patologia. Relata-se o caso de uma paciente com vasculopatia livedoide de acometimento de membros inferiores. (AU)

Livedoid vasculopathy is a vascular skin disease resulting from thrombogenic occlusion of dermal blood vessels. It presents with erythematous, purpuric macules or papules on the lower limbs, which can lead to chronic and recurrent painful ulceration. With its progression, there may be scarring leading to the appearance of areas of fibrosis and atrophic, irregular, and whitish scars, which gave this name to the pathology. The case of a patient with livedoid vasculopathy affecting the lower limbs is reported. (AU)

Harlequin syndrome: a case report / Síndrome de arlequín: reporte de un caso

El síndrome de Arlequín es una condición neurológica poco común, la mayoría de las veces benigna. Por lo general la mayor parte de los casos son de causa idiopática (aunque existen causas secundarias). Esta afección consiste en la aparición de eritema e hiperhidrosis facial unilateral desencadenado por el ejercicio, calor, emociones o estrés, la que se produce debido a una disfunción contralateral de la vía simpática vasodilatadora y sudomotora. Se presenta el caso de un paciente de sexo masculino de 49 años, que relata presentar un cuadro de 15 años de evolución caracterizado por la aparición de eritema y sudoración excesiva de la hemicara derecha, la cual termina abruptamente en la línea media de la cara, gatillado por el ejercicio y el calor en verano, mientras que la hemicara izquierda presenta anhidrosis sin eritema.

The Harlequin syndrome is a rare neurological condition, most of the time benign. In general, most cases are idiopathic (although there are secondary causes). This condition consists in the appearance of unilateral facial erythema and hyperhidrosis triggered by exercise, heat, emotions or stress, which occurs due to a contralateral dysfunction of the sympathetic vasodilator and sudomotor pathway. We present the case of a 49-year-old male patient, with no relevant morbid history, who reports a medical history of 15 years of evolution, characterized by the appearance of erythema and excessive sweating of the right side of his face, which ends abruptly in the middle line of the face, triggered by exercise and heat during the summer. While the left side presents anhidrosis without erythema.

Estudio del efecto citotóxico e irritativo de jabones para la limpieza cutánea / Study of the cytotoxic and irritant effects of skin cleansing soaps

Resumen Introducción: El jabón para el aseo cutáneo es de empleo común entre la población, sin embargo, es posible que cause daño a las células de la piel y modifique la barrera cutánea. Objetivo: Determinar el efecto citotóxico de los jabones en queratinocitos cultivados in vitro y correlacionarlo con la irritación clínica. Método: Se realizó una encuesta para conocer los jabones comerciales más utilizados y su cantidad; posteriormente, se evaluó su citotoxicidad en cultivos de queratinocitos humanos mediante el método de resazurina. Los jabones con mayor y menor citotoxicidad se aplicaron en piel de voluntarios sanos para evaluar su efecto en la barrera cutánea mediante ensayos de colorimetría y pérdida transepidérmica de agua. Resultados: De los jabones analizados, 37 % demostró ser tóxico para los queratinocitos in vitro. El jabón con mayor toxicidad indujo el mayor índice de eritema y pérdida transepidérmica de agua, en comparación con el jabón menos tóxico y el vehículo empleado como solución control. Conclusión: Los jabones comercializados para el aseo cutáneo pueden incluir ingredientes químicos que dañan los queratinocitos humanos y causan irritación subclínica de la barrera cutánea. Su utilización puede agravar dermatosis preexistentes, generar dermatitis xerósica o de contacto irritativa y causar atrofia y dermatoporosis.

Abstract Introduction: The use of soap for skin cleansing is common among the population. However, it is possible that it causes damage to skin cells and disrupts the skin barrier. Objective: To determine the cytotoxic effect of soaps on in vitro-cultured keratinocytes and to correlate it with clinical irritation. Method: A survey was conducted to find out the most widely used commercial soaps and their number. Subsequently, their cytotoxicity was evaluated in human keratinocyte cultures using the resazurin assay. The soaps with the highest and lowest cytotoxicity were applied to the skin of healthy volunteers to assess their effect on the skin barrier using colorimetry and transepidermal water loss (TEWL) assays. Results: Of the analyzed soaps, 37 % were shown to be toxic to keratinocytes in vitro. The soap with the highest toxicity induced the highest rate of erythema and TEWL, in comparison with the least toxic soap and the vehicle used as the control solution. Conclusion: Soaps marketed for skin cleansing can contain chemical ingredients that damage human keratinocytes and cause skin barrier subclinical irritation. Their use can worsen preexisting dermatoses, generate xerotic or irritant contact dermatitis, and cause atrophy and dermatoporosis.

Systemic sporotrichosis in an alcoholic patient

Abstract A 44-year-old male patient presented with nodules that evolved with inflammation, following drainage of seropurulent secretion and ulceration. The patient had a 6 year-history of alcohol addiction and reported contact with cats. At the physical examination, the patient had skin-colored and erythematous nodules, and ulcers covered with thick, blackened crusts on the face, trunk and limbs. A culture of a nodule fluid revealed growth of Sporotrix sp. He also had pulmonary involvement and therefore the disease was classified as systemic sporotrichosis, a rare form that usually affect patients infected with HIV. Chronic alcohol abuse was considered the factor of immunosuppression for the patient.
