Erupción fija por luz solar, una serie de 13 casos en Bogotá, Colombia / Fixed Sunlight Eruption: A Series of 13 Cases in Bogotá, Columbia

Desde 1975 se han publicado algunos casos que asocian la radiación ultravioleta como un desencadenante de erupciones cutáneas fijas (erupción o exantema fijo por luz solar o síndrome de fotosensibilidad localizada de amplio espectro). Describimos los casos de 13 pacientes con esta dermatosis, 4 varones (30,8%) y 9 mujeres (69,2%), con edades comprendidas entre los 28 y los 56 años, atendidos en un centro de referencia en dermatología en Bogotá, Colombia. Las lesiones se localizaron en la cara interna de los muslos, los glúteos, la región poplítea, la axilar anterior y posterior y el dorso de los pies. La prueba de fotoprovocación logró la reproducción de las lesiones en todos los casos en las áreas afectadas y la histopatología reveló cambios similares a los descritos en los eritemas fijos por medicamentos. Esta enfermedad podría corresponder a un subtipo de erupción fija, aunque no se descarta que sea una dermatosis diferente con una patogenia común.(AU)

Few reports describing an association between UV radiation and fixed skin eruptions have been published since 1975. These reactions have received various names, including fixed sunlight eruption, fixed exanthema due to UV radiation, and broad-spectrum abnormal localized photosensitivity syndrome. We present a series of 13 patients (4 men [30.8%] and 9 women [69.2%]) aged between 28 and 56 years who were evaluated for fixed eruptions induced by UV radiation at a dermatology referral hospital in Bogotá, Colombia. The lesions were located on the inner thighs, buttocks, popliteal region, anterior and posterior axilla, and dorsum of the feet. Photoprovocation reproduced lesions in all the affected areas, and histopathology showed changes similar to those seen in fixed drug eruptions. While these UV-provoked reactions may be a type of fixed skin eruption, we cannot rule out that they may also be a distinct condition that simply shares a pathogenic mechanism with fixed eruptions.(AU)

Exantema en enfermedad por virus de inmunodeficiencia humana, ¿manifestación de infección o reacción alérgica?

Paciente varón que presentó exantema maculopapular, no pruriginoso, sin afectación palmoplantar, luego de recibir tratamiento con trimetoprim/sulfametoxazol por siete días debido a sintomatología gastrointestinal. Tras realizar historia clínica completa y con pruebas de cuarta generación se confirmó infección por VIH. Al quinto día de tratamiento antirretroviral presentó nuevas lesiones eritematosas con descamación gruesa, pruriginosas, edema facial y eosinofilia. Se realizó una biopsia de piel que reportó una dermatitis liquenoide, con espongiosis, degeneración vacuolar de la capa basal, queratinocitos necróticos e infiltrado de eosinófilos, características que favorecen la reacción por drogas. El tratamiento consistió en interrumpir la terapia combinada, uso de corticoides sistémicos, antihistamínicos y ya que, no se trató de un cuadro severo, se reinició el tratamiento antirretroviral sin complicaciones.

A male patient presented with a maculopapular, non-pruritic rash, without palmoplantar involvement, after receiving treatment with trimethoprim/sulfamethoxazole for seven days due to gastrointestinal symptoms. After taking a complete medical history and using fourth-generation tests confirmed HIV infection. On the fifth day of antiretroviral treatment, he presented new erythematous lesions with thick, pruritic scaling, facial edema and eosinophilia. A skin biopsy reported lichenoid dermatitis, with spongiosis, vacuolar degeneration of the basal layer, necrotic keratinocytes and eosinophil infiltrate, characteristics that favor drug reaction. The treatment consisted of interrupting the combined therapy, using systemic corticosteroids, antihistamines and since it was not a severe condition, antiretroviral treatment restarted without complications.

Características epidemiológicas de pacientes con viruela símica y su relación con eventos de hospitalización en Colombia / Epidemiological characteristics of patients with monkeypox and their relationship with hospitalization events in Colombia

Fundamentos: Desde inicio de 2022 se ha presentado un brote inusual de viruela símica en países no endémicos que ha alertado a la comunidad internacional. En Colombia, no existen trabajos recientes sobre la epidemiología de los pacientes en esta nueva epidemia. Por tanto, el objetivo del presente trabajo fue establecer las características epidemiológicas de pacientes con viruela símica y su relación con la frecuencia de hospitalización y otras variables de notificación clínica. Métodos:Se realizó un estudio observacional, analítico y transversal sobre los casos de viruela símica en Colombia entre mayo y septiembre de 2022. Se aplicó la prueba U de Mann-Whitney para el contraste de hipótesis entre hospitalización y variables sociodemográficas y de notificación cuantitativas; se usó la prueba exacta de Fisher para el contraste con las cualitativas. Resultados: Entre mayo y septiembre de 2022 se presentaron 1.260 casos de viruela símica en Colombia, el 75% de estos se registraron en Bogotá D.C. El 99% (1.248) de los contagiados eran de sexo masculino, con mediana de 32 años. El 82% de los pacientes eran de estratos 2 y 3 (ingresos bajo a medio-bajo). La fuente de infección era desconocida en poco más del 80% de los casos. Menos del 1% pertenecían a grupos étnicos. Solo el 3% requirió hospitalización. Se encontró asociación estadística significativa entre frecuencia de hospitalización, ser mujer (p=0,038), afrocolombiano (p=0,024) y régimen subsidiado (p=0,009). No se encontró asociación de hospitalización con la edad, pero sí con los días desde el inicio de síntomas/exantema hasta la notificación/diagnóstico (p<0,05). Conclusiones: Los casos de viruela símica se concentran en la capital y otros departamentos andinos de Colombia. La mayoría de estos cursan sin gravedad, sin fallecimientos. Los hombres son el grupo poblacional más afectado...(AU)

Background: Since the beginning of 2022, there has been an unusual outbreak of monkeypox in non-endemic countries that has alerted the international community. In Colombia, there are no recent studies on the epidemiology of patients in this new epidemic. Therefore, aim of this article was to establish the demographic and clinical characteristics of patients with monkeypox and their relationship with the frequency of hospitalization and other variables of clinical notification. Methods: An observational, analytical, and cross-sectional study on monkeypox cases in Colombia between May and September 2022 was executed. Mann-Whitney U test was applied to contrast hypotheses between hospitalization and sociodemographic and quantitative notification variables; Fisher’s exact test was used to contrast with the qualitative ones. Results: Between May and September 2022, there were 1,260 cases of monkeypox reported in Colombia, 75% of the these were registered in Bogotá D.C. 99% (1,248) of those infected were male with a median age of 32.82% of the patients were from strata 2 and 3 (low to medium-low income). The source of infection was unknown in just over 80% of cases. Less than 1% belonged to ethnic groups. Only 3% required hospitalization. A significant statistically association was found between the frequency of hospitalization, being a woman (p=0.038), Afro-Colombian (p=0.024) and subsidized regime (p=0.009). No association of hospitalization was found with age, but it was found with the days from the onset of symptoms/rash to notification/diagnosis (p<0.05). Conclusions: Monkeypox cases are concentrated in the capital and other Andean departments of Colombia. Most of these progress without seriousness, without deaths. Men are the most affected population group. Women, afro-colombians and subsidized patients deserve special attention because they are more prone to hospitalization...(AU)

Toxicidad muco-cutánea: un desafío en el tratamiento oncológico / Mucocutaneous toxicity: a challenge in oncological treatment

El tratamiento combinado con inhibidores de tirosina quinasa e inmunoterapia en el cáncer de pulmón avanzado con mutación del EGFR es un enfoque emergente en la investigación clínica. Algunos estudios preliminares han mostrado resultados prometedores, con mejorías en la respuesta tumoral y la supervivencia global en comparación con la monoterapia. Sin embargo, esta combinación puede aumentar el riesgo de eventos adversos, por lo que se requiere un se-guimiento estrecho y una atención médica especializada. Se presenta el caso de un varón de 57 años con adenocarcinoma de pulmón que manifestó exantema generalizado grado 3 con lesiones pápulo-pustulosas, paroniquia y tricomegalia secundario al tratamiento con la-zertinib-amivantamab. Además, el paciente desarrolló una proctalgia crónica con mal control álgico debido a la aparición de úlceras anales e hipertonía del esfínter anal. (AU)

The combined treatment with tyrosine kinase inhibitors and immunotherapy in advanced lung cancer with EGFR mutation is an emerging approach in clinical research. Some preliminary studies have shown promising results, with improvements in tumor response and overall survival compared to monotherapy. However, this combination may increase the risk of adverse events, necessitating close monitoring and specialized medical attention. We present the case of a 57-year-old male with lung adenocarcinoma who manifested grade 3 generalized exanthema with papulopustular lesions, paronychia and trichomegaly secondary to treatment with lazertinib-amivantamab. Additionally, the patient developed chronic proctalgia with poorly controlled pain due to the presence of anal ulcers and anal sphincter hypertonia. (AU)

Manejo de reações adversas dermatológicas em pacientes submetidos à terapia quimioterápica antineoplásica / Management of dermatological adverse reactions in patients undergoing antineoplastic chemotherapy

Objetivo: o presente estudo tem como objetivo reunir recomendações de cuidados considerando a prevenção e tratamento de lesões de pele induzidas pelo tratamento com quimioterápicos antineoplásicos, de acordo com os estudos e consensos atuais. Metodologia: realizou-se um estudo bibliográfico para levantamento das relações entre os principais fármacos antineoplásicos e suas intercorrências dermatológicas, bem como seus respectivos manejos, para subsidiar a orientação e aconselhamento aos profissionais de saúde que acompanham o paciente oncológico. Resultado: os principais problemas dermatológicos decorrentes do uso de antineoplásicos correspondem às lesões de pele, tais como a descoloração, hiperpigmentação, fotossensibilidade, eritemas, descamação e prurido. Também são recorrentes os efeitos adversos que acometem os pelos e cabelos, resultando em alopecia, e a modificação do crescimento e lesões nas unhas. Tratamentos específicos para cada caso são capazes de amenizar ou reverter os problemas. Conclusão: as reações adversas aos medicamentos envolvendo quimioterapia são frequentes na prática oncológica, e variam em termos de frequência e gravidade, atingindo diversos anexos cutâneos. O adequado manejo destes efeitos melhora a integridade da pele e demais estruturas, proporcionando a esses pacientes a melhoria da autoestima e da qualidade de vida.

Objective: the present study aims to gather care recommendations considering the prevention and treatment of skin lesions induced by treatment with antineoplastic chemotherapy, according to current studies and consensus. Methodology: a bibliographical study was carried out to survey the relationships between the main antineoplastic drugs and their dermatological intercurrences, as well as their respective management, to subsidize the guidance and counselling of health professionals who treat cancer patients. Result: the main dermatological problems arising from the use of antineoplastic agents correspond to skin lesions, such as discoloration, hyperpigmentation, photosensitivity, erythema, scaling and pruritus. Adverse effects that affect hair and body hair are also recurrent, resulting in alopecia, and the modification of growth and lesions on the nails. Specific treatments for each case can alleviate or reverse the problems. Conclusion: adverse drug reactions involving chemotherapy are frequent in oncology practice, and vary in terms of frequency and severity, affecting various skin appendages. Proper management of these effects improves the integrity of the skin and other structures, providing these patients with improved self-esteem and quality of life.

Fixed Sunlight Eruption: A Series of 13 Cases in Bogotá, Columbia. / Erupción fija por luz solar, una serie de 13 casos en Bogotá, Colombia.

Few reports describing an association between UV radiation and fixed skin eruptions have been published since 1975. These reactions have received various names, including fixed sunlight eruption, fixed exanthema due to UV radiation, and broad-spectrum abnormal localized photosensitivity syndrome. We present a series of 13 patients (4 men [30.8%] and 9 women [69.2%]) aged between 28 and 56 years who were evaluated for fixed eruptions induced by UV radiation at a dermatology referral hospital in Bogotá, Colombia. The lesions were located on the inner thighs, buttocks, popliteal region, anterior and posterior axilla, and dorsum of the feet. Photoprovocation reproduced lesions in all the affected areas, and histopathology showed changes similar to those seen in fixed drug eruptions. While these UV-provoked reactions may be a type of fixed skin eruption, we cannot rule out that they may also be a distinct condition that simply shares a pathogenic mechanism with fixed eruptions.

Introduction: Molluscum contagiosum is a common skin disease inchildren. The infection is caused by the molluscum contagiosumvirus. It presents as single or multiple spherical, shiny, pearlywhite papules with a central dimple. In some cases, it can producesecondary inflammatory reactions that it is necessary to recognizesuch as molluscum dermatitis or Gianotti-Crosti-like syndrome. Case report: A four year old patient with a history of molluscumcontagiosum infection developed erythematous lesions in the elbows and knees, suggestive of a secondary inflammatory reaction,Gianotti-Crosti-like syndrome. Treatment with topical corticosteroids was administered with full resolution of the skin lesions. Comments: Gianotti-Crosti-like syndrome secondary to molluscumcontagiosum is a rare inflammatory reaction that pediatriciansneed to be aware of for a proper diagnosis and treatment. Thissyndrome tends to resolve spontaneously, although in symptomaticcases treatment with topical corticosteroids and oral antihistaminemay be required.(AU)

Perfil epidemiológico dos casos suspeitos de sarampo e rubéola notificados no SINAN, Brasil, 2007 a 2016 / Epidemiological profile of suspected cases of measles and rubella notified on SINAN, Brazil, 2007 to 2016

Descrever os casos suspeitos de sarampo e rubéola notificados no Sistema de Informação de Agravos de Notificação (Sinan), Brasil, 2007 a 2016. Métodos: Os dados foram extraídos do Sinan, referentes aos anos de 2007 a 2016. As variáveis utilizadas foram os números de notificações de casos de sarampo e rubéola por regiões e ano, idade, sexo, hospitalização, estado gestacional, histórico vacinal, realização de bloqueio vacinal, coletas sorológicas (S1 e S2), sinais e sintomas, investigação adequada, critério de confirmação ou descarte e classificação final do caso. Resultados: Entre 2007 e 2016 houve 127.802 casos suspeitos de sarampo e rubéola notificados. Aproximadamente 92% dos casos foram investigados, a maioria em menores de cinco anos. Os sintomas mais frequentes foram tosse (40%) e coriza (38%). Como instrumento de vigilância foi coletado sangue para confirmação laboratorial em 87% das notificações. A maioria dos casos de sarampo ocorreu entre os anos de 2011 e 2015, relacionados a casos importados, totalizando 1.443 casos; para rubéola, 10.125 casos foram confirmados. Foram descartados 1,3% (1.698/127.802) e 5,1% (6.555/127.802) das notificações de sarampo e rubéola, respectivamente. Foram ignorados 9% (11.523/127.802) para sarampo e 49% (62.978/127.802) para rubéola. Conclusão: A vigilância dos casos de doenças exantemáticas permitiu demonstrar a situação dos casos de doenças exantemáticas circulantes no país como importante ferramenta de saúde pública. O grande número de casos descartados classificados como ignorados merece atenção, no sentido de melhorar o encerramento dos casos suspeitos notificados

To describe the suspected cases of measles and rubella notified in the Notifiable Diseases Information System (Sinan), Brazil, from 2007 to 2016. Methods: Data were extracted from Sinan referring to the years 2007 to 2016. The variables used were the number of notifications of measles and rubella cases by region and year, age, gender, hospitalization, gestational status, vaccination history, vaccination blockade, serological collections (S1 and S2), signs and symptoms, adequate investigation, confirmation criteria or disposal and final case classification. Results: Between 2007 and 2016, there were 127,802 suspected cases of measles and rubella reported. Approximately 92% of cases were investigated, mostly in children under five years of age. The most frequent symptoms were cough (40%) and runny nose (38%). As a surveillance tool, blood was collected for laboratory confirmation in 87% of notifications. Most Measles cases occurred between 2011 and 2015, related to imported cases, totaling 1,443 cases; for Rubella 10,125 cases were confirmed. 1.3% (1,698/127,802) and 5.1% (6,555/127,802) of measles and rubella notifications, respectively, were discarded. 9% (11,523/127,802) for measles and 49% (62,978/127,802) for rubella were ignored. Conclusion: Surveillance of cases of exanthematous diseases allowed demonstrating the situation of cases of exanthematous diseases circulating in the country as an important public health tool. The large number of discarded cases classified as ignored deserves attention, in order to improve the closing of notified suspected cases

Eritema Multiforme, Una Rara Presentación De Exantema En Población Pediátrica. A Propósito De Un Caso. / Erythema Multiforme, A Rare Occurrence Of Exanthema In The Pediatric Population. On The Subject Of A Case.

El Eritema multiforme (EM) o eritema polimorfo es una enfermedad aguda de la piel de naturaleza inmunológica con o sin compromiso de mucosas, que puede comportarse como crónica recurrente. Se presenta con lesiones cutáneas en diana distintivas, a menudo acompañado de úlceras o bullas en mucosas (oral, genital u ocular). Entre sus formas clínicas se distingue: una forma menor caracterizado por un síndrome cutáneo leve y su forma mayor que se manifiesta como una afectación cutánea con daño mucoso marcado. Entre sus principales diagnósticos diferenciales se encuentran el Síndrome de Stevens-Johnson (SSJ) y Síndrome de Lyell (Necrólisis epidérmica tóxica (NET)). Tiene una incidencia estimada < 1%, siendo su forma mayor levemente más frecuente que su forma menor (0.8-6 por millón/año). Puede darse a cualquier edad, presentando un peak de incidencia entre los 20 y 30 años, predominando ligeramente el sexo masculino con una proporción 3:2, sin predilección racial. Su presentación en edad pediátrica es rara, más aún en la primera infancia. En esta población es más frecuente el EM menor recurrente. En el presente texto se reporta un caso de EM en población pediátrica como una rara forma de presentación exantemática, abordado en el Servicio de Pediatría del Complejo Asistencial Dr Victor Rios Ruiz (CAVRR)en la ciudad de Los Ángeles, Chile en el presente año.

Erythema multiforme (EM) also known as polymorph erythema is an acute skin disease of immunological nature with or without mucous membrane involvement, which may behave as chronic recurrent. It presents with distinctive targets like skin lesions, often together with ulcers or bullae in mucous membranes (oral, genital or ocular). Among its clinical forms are: a minor form characterized by a mild skin syndrome and its major form that manifests as a skin disease with marked mucosal damage. Among its main differential diagnoses are Stevens-Johnson Syndrome (SJS) and Lyell Syndrome (Toxic Epidermal Necrolysis (TEC)). It has an estimated incidence < 1%, with its major form being slightly more frequent than its minor form (0. 8-6 per million/year). It can occur at any age, presenting a peak incidence at the age between 20 and 30 years, with a slight predominance of males with a 3:2 ratio, without racial predilection. Its presentation in pediatric age is rare, even more so in early childhood. Minor recurrent EM is more common in this population. This paper reports a case of EM in the pediatric population as a rare form of exanthematic presentation, addressed at the Department of Pediatrics of the Complejo Asistencial Victor Rios Ruiz (CAVRR) in the city of Los Angeles, Chile this year.

Análise das Doenças Exantemáticas de Notificação Compulsória no Estado de Santa Catarina Entre 2009 e 2019 / Analysis of Exanthematous Diseases of Compulsory Notification in the State of Santa Catarina from 2009 to 2019

Introdução: Doenças exantemáticas (DE) são patologias infecciosas agudas, que têm como característica principal a manifestação dermatológica. Entre elas, sarampo e rubéola são de notificação compulsória. A permanência da circulação destes vírus no mundo tem causado surtos em diversas regiões, como em SC, embora sejam doenças evitáveis por meio da imunização. Métodos: Trata-se de um estudo de delineamento ecológico, constituído de casos notificados por DE em SC no período de 2009 a 2019. Os dados foram coletados no Sistema Nacional de Agravos e Notificações (SINAN/DATASUS). Resultados: Foram notificados 190 casos de DE, 41,57% na faixa etária de 20 a 29 anos, 55,91% masculinos, 88,70% brancos e 2,15% gestantes. Houve confirmação laboratorial em 85,16%, e 72,72% foram causados pelo vírus sarampo selvagem. Exantema predominou em novembro em 46,77%, e febre em outubro, em 41,93%. Tosse esteve presente em 89,24%, coriza em 67,20% e conjuntivite em 50,53%. A macrorregião com maior média de cobertura vacinal foi a Grande Oeste, com 86,85%, e a menor, a Grande Florianópolis, com 72,07%. A maior incidência de sarampo ocorreu em 2019 no Nordeste e Planalto Norte com 11,34, e a de rubéola 0,13 no Grande Oeste no mesmo ano. Foi realizado bloqueio vacinal em 95,34% dos casos, e 64,28% foram autóctones. Conclusão: Observou-se que as DE acometem indistintamente ambos os sexos, etnias e idades, sendo a vacinação a forma mais eficaz de prevenir surtos. A reemergência ocorrida no estado foi consequência das baixas taxas de cobertura vacinal, apontando para a necessidade de melhorias nas ações de imunização.

Introduction: Exanthematous diseases (ED) are acute infectious pathologies that present mainly dermatological manifestations. Among them, measles and rubella demand compulsory notification. The continued circulation of these viruses has caused outbreaks in several regions, such as Santa Catarina, although they are preventable diseases through immunization. Methods: This is a study of ecological design consisting of cases notified of ED in SC from 2009 to 2019. Data collection from the National System of Diseases and Notifications (SINAN/DATASUS). Results: 190 cases of ED were notified, 41.57% in the age group 20 to 29 years, 55.91% male, 88.70% white, and 2.15% pregnant women. Laboratory confirmation occurred in 85.16%, and the wild measles virus was the cause in 72.72%. Exanthema predominated in November with 46.77% and fever in October with 41.93%. Cough was present in 89.24%, coryza in 67.20%, and conjunctivitis in 50.53%. The macro-region with the highest average vaccination coverage was the great west, 86.85%, and the lowest was greater Florianópolis, 72.07%. The highest incidence of measles occurred in 2019. Northeast and North Plateau scored 11.34, and rubella at 0.13 in the Great West in the same year. Vaccine block occurred in 95.34% of cases, and 64.28% were autochthonous. Conclusions: The study observed that EDs affect both sexes, ethnicities, and ages indistinctly, and vaccination is the most effective way to prevent outbreaks. The re-emergence that occurred in the state was a consequence of low rates of vaccination coverage, pointing to the need for improvements in immunization activities

Características de los primeros casos reportados como sospechosos de Monkeypox en el Perú / Characteristics of the first cases reported as suspected Monkeypox in Peru

RESUMEN Se presenta el caso de 9 pacientes reportados en el contexto de la alerta sanitaria por el aumento de casos de infección por el virus de Monkeypox en el mundo en países no endémicos. Es importante conocer de forma práctica los criterios epidemiológicos y clínicos más importantes para el descarte de viruela símica en el actual contexto de trasmisión en el Perú. Se discute los criterios de los casos confirmados respecto a otras enfermedades que son parte del diagnóstico diferencial como varicela, síndrome mano pie boca, entre otros.

ABSTRACT The case of 9 patients reported in the context of the health alert due to the increase in cases of Monkeypox virus infection in the world in non-endemic countries is presented. It is important to know in a practical way the most important epidemiological and clinical criteria that make us think about ruling out Monkeypox in the current context of transmission in Peru. The characteristics of the confirmed cases are discussed versus those of other diseases that are part of the differential diagnosis such as chickenpox, hand-foot-mouth syndrome, etc.

Enfermedad de Kawasaki en pediatría: caso clínico

la enfermedad de Kawasaki (EK) es una vasculitis multisistémica que se presenta en la infancia. Por lo general es una afección aguda, febril, autolimitada, de etiología desconocida y puede desarrollar alteraciones cardiovasculares; su expresión clínica es variable: presenta inflamación de los vasos de mediano calibre y de múltiples tejidos: pulmonar, meníngeo, cardiaco, urinario, gastrointestinal, musculoesquelético, neurológico o linfático. El diagnóstico y el tratamiento buscan disminuir la duración de los síntomas y prevenir la presencia de aneurismas coronarios.

Kawasaki disease (KD) is a multisystemic vasculitis that presents in childhood. It is usually an acute, febrile, self-limited disease of unknown etiology and may develop cardiovascular alterations; its clinical expression is variable as it presents inflammation of medium caliber vessels and multiple tissues: pulmonary, meningeal, cardiac, urinary, gastrointestinal, musculoskeletal, neurological or lymphatic. Diagnosis is clinical, and treatment aims to reduce the duration of clinical symptoms and prevent the presence of coronary aneurysms. Objective: to describe the clinical case of an infant patient with KD, in which clinical criteria characteristic of this pathology were identified. Case report: a 22-month-old male patient was admitted to the emergency room with a 14-day evolutionary clinical picture consisting of fever, emetic episodes, abdominal pain, unresponsive to acetaminophen, and diarrheal episodes. Two days later, he manifested generalized exanthema in the inguinal region that spread to the right testicle, back, and thorax. Subseguently, he presented bilateral nonpurulent conjunctivitis for three days. He received treatment with topical steroids and oral antihistamines; partial improvement with subseguent evolution in right testicularedema and bilateral desquamation in hands and feet. KD was suspected, a transthoracic echocardiogram was sent without coronary aneurysmal dilatations, and treatment with ASA was started without indication, given the evolution of immunoglobulin. Conclusions: KD is infrequent in childhood and should be suspected in patients with prolonged febrile symptoms unresponsive to conventional treatments and in whom the presence of other pathologies is ruled out.

a doença de Kawasaki (DK) é uma vasculite multissistêmica que ocorre na infância. Geralmente é uma doença aguda, febril, autolimitada, de etiologia desconhecida, podendo desenvolver alterações cardiovasculares; sua expressão clínica é variável, apresentando inflamação de vasos de médio porte e de múltiplos tecidos: pulmonar, meníngeo, cardíaco, urinário, gastrointestinal, musculoesquelético, neurológico ou linfático. O diagnóstico é clínico e o tratamento visa reduzir a duração dos sintomas clínicos e prevenir a presença de aneurismas coronábanos. Objetivo: descrever o caso clínico de um paciente infantil com DK, no qual foram identificados critérios clínicos característicos dessa patologia. Caso clínico: paciente do sexo masculino, 22 meses de idade meses de idade, admitido no departamento de emergência com um curso clínico de 14 dias, consistindo em febre, episódios eméticos e dor abdominal, sem resposta ao acetaminofeno, além de episódios diarreicos. Dois dias depois, ele desenvolveu uma erupção cutánea generalizada na região inguinal que se espalhou para o testículo direito, costas e tórax. Posteriormente, ele apresentou conjuntivite bilateral não purulenta por três dias. Ele foi tratado com esferoides tópicos e anti-histamínicos orais; houve melhora parcial com posterior evolução do edema testicular direito, descamação bilateral nas mãos e nos pés. Suspeitou-se de DK, portanto foi realizado ecocardiograma transtorácico sem dilatações aneurismáticas coronarianas e iniciado tratamento com AAS, sem indicação devido ao tempo de evolução da imunoglobulina. Conclusões: a DK não é frequente na infância e deve ser suspeitada em pacientes com sintomas febris prolongados que não respondem aos tratamentos convencionais e nos quais a presença de outras patologias é descartada.

Manifestaciones cutáneas en pacientes con COVID-19. Estudio prospectivo / Skin manifestations in patients with COVID-19. A prospective study

Resumen Desde marzo 2020 se describieron lesiones cutáneas asociadas a COVID-19. Los objetivos del estudio fueron caracterizar las lesiones cutáneas en estos pacientes, analizar su relación temporal, asociación con la gravedad de la enfermedad, los síntomas extracutáneos y parámetros de laboratorio. Es un estudio prospectivo, observacional, analítico y de corte transversal, en internados con diagnóstico de COVID-19. Se catalogaron las dermatosis en primarias y secundarias. Se incluyeron 45 pacientes, 44.4% con dermatosis primarias y 53.3% con lesiones secundarias. La edad media fue de 46 años (DS: 17), con predominio del sexo masculino (68.9%). Las lesiones primarias aparecieron luego de una mediana de 5 días (RIC: 3-10) del inicio de los síntomas de COVID-19 y las secundarias luego de 14.5 días (RIC: 7-20). Las dermatosis primarias fueron: exantema maculopapuloso (65%), urticariforme (20%, la mitad con lesiones vesiculosas), livedo reticular (10%) y púrpura (5%). Las dermatosis secundarias más frecuentes fueron reacciones adversas a fármacos (37.1%) y dermatosis infecciosas (25.9%). El exantema maculopapuloso se asoció a COVID-19 moderado y las lesiones por presión a COVID-19 grave (p < 0.05). El hallazgo de neutrofilia fue mayor entre aquellos con dermatosis infecciosas secundarias (p < 0.05). No se encontraron diferencias significativas al evaluar otros parámetros de laboratorio, ni síntomas extracutáneos. Este trabajo muestra las manifestaciones cutáneas en internados con COVID-19. El patrón más prevalente fue el exantema maculopapuloso que se asoció con la forma moderada de la enfermedad. La aparición de lesiones luego de las 2 semanas del inicio de los síntomas de COVID-19 se asoció a dermatosis secundarias.

Abstract As of March 2020, skin lesions associated with COVID-19 have been described. The objectives of the study were to char acterize the skin lesions in these patients, analyze their temporal relationship, association with the severity of the disease, extracutaneous symptoms and laboratory parameters. A prospective, observational, analytical and cross-sectional study was conducted in hospitalized patients diagnosed with COVID-19. Dermatoses were clas sified as primary and secondary. Forty-five patients were included, 44.4% with primary dermatoses and 53.3% with secondary lesions. The mean age was 46 years (SD: 17), with a male predominance (68.9%). The primary lesions appeared after a median of 5 days (IQR: 3-10) from the onset of COVID-19 symptoms and the secondary ones after 14.5 days (IQR: 7-20). The primary dermatoses found were maculopapular rash (65%), urticarial (20%, half with vesicular lesions), livedo reticular (10%) and purpura (5%). The most frequent secondary dermatoses were adverse drug reactions (37.1%) and infectious dermatoses (25.9%). Maculopapular rash was associated with moderate COVID-19 and pressure injuries with severe COVID-19 (p < 0.05). The finding of neutrophilia was higher among those with secondary infectious dermatoses (p < 0.05). No significant differences were found when evaluating other laboratory parameters. This work shows the skin manifestations in patients hospitalized with COVID-19 in our environment. The most prevalent pattern was the maculopapular rash that was associated with the moderate form of the disease. The appearance of lesions 2 weeks after the onset of COVID-19 symptoms was associated with secondary dermatoses.

Exantema flexural intertriginoso simétrico relacionado a polivalente tópico / Symmetric intertriginous flexural rash related to topical polyvalent

RESUMEN Se presenta el caso de un paciente de 12 años, que 5 horas después de la aplicación de un polivalente tópico presentó aumento de volumen a nivel de pene y escroto, cursando con eritema en zonas flexurales de ingle, axila, dorso de pies y marcado eritema simétrico en nalgas con piel empastada, refiriendo intenso prurito en escala 9/10 en las lesiones. En los exámenes de laboratorio hemograma sin leucocitosis y eosinófilos 18%. Ecografía doppler testicular normal. Se indicó corticoide tópico y prednisona, con remisión de prurito y eritema siendo dado de alta a los 6 días con escasa descamación en glúteos. Por cumplir con los criterios de exposición a drogas: eritema en forma de V, compromiso flexural, ausencia de repercusión sistémica y afectación simétrica, se reportó como un exantema flexural intertriginoso simétrico relacionado a drogas (SDRIFE).

ABSTRACT The case of a 12-year-old patient is presented, who 5 hours after the application of a topical polyvalent presents an increase in volume at the level of the penis and scrotum, presenting with erythema in flexural areas of the groin, armpit, back of the feet and marked erythema symmetrical in buttocks with pasty skin, referring to intense itching on a 9/10 scale in the lesions. In laboratory tests hemogram without leukocytosis and eosinophils 18%. Normal testicular echo-Doppler. Topical corticosteroid and prednisone were indicated, with remission of pruritus and erythema, being discharged 6 days later. With little desquamation in the buttocks, due to meeting the criteria for drug exposure, V-shaped erythema, flexural compromise, absence of systemic repercussion and symmetric involvement is reported as a drug-related symmetric intertriginous flexural rash (SDRIFE).

Exantema en neonato irritable / Irritable newborn rash

La escabiosis es la infestación cutánea por el parásito Sarcoptes scabiei var. hominis. A diferencia de la forma clásica que afecta a niños y adultos, la escabiosis neonatal presenta una serie de características distintivas que dificultan su diagnóstico. Presentamos un caso de escabiosis neonatal cuyo diagnóstico supuso un reto ante la ausencia de antecedentes epidémicos familiares (AU)

Scabies is the cutaneous infestation by the parasite Sarcoptes scabiei var. hominis. There are some clinical variants, among which the neonatal one stands out, which typically affect the face and scalp, unlike classic variant. We present a case of neonatal scabies that supposed a challenge in the absence of a family epidemic history. (AU)

Síndrome purpúrico de distribución atípica por parvovirus B19 en una adolescente / Atypical involvement of purpuric syndrome caused by parvovirus B19: case report in a 12-year-old female

Resumen El parvovirus B19 es causante de una variedad de enfermedades exantemáticas durante la infancia y adolescencia, como el eritema infeccioso y el síndrome papular purpúrico en guante y calcetín. Este último es una acrodermatitis aguda, inusual y benigna, que puede asociarse a aftas orales, fiebre y otros síntomas constitucionales. Existen casos atípicos como la púrpura febril en otras localizaciones, sin cumplir la distribución característica en guante y calcetín de forma simétrica o con un mayor componente de eritrodermia. Presentamos el caso de una adolescente de 12 años con un síndrome papular purpúrico de distribución atípica por parvovirus B19.

Abstract Parvovirus B19 is the cause of a variety of exanthematous diseases during childhood and adolescence, such as erythema infectiosum and papular purpuric gloves and socks syndrome. This is an unusual, benign and acute acrodermatitis. Aphtous stomatitis, fever and other systemic symptoms can be associated with the eruption of the purpuric rash. Uncommon patterns such as asymmetrical distribution or erythematous involvement llave recently been described as additional features of PVB19-associated purpuric petechial eruption. This is a case report of a 12-year-old female with an atypical involvement of a papular-purpuric syndrome caused by human parvovirus B19.
