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.

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.

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

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.

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).

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.

Pitiriasis rosada como manifestación dermatológica de infección por SARS-CoV-2: a propósito de un caso / Pityriasis rosea as a cutaneous manifestation associated with SARS-CoV-2 infection: case report

Las manifestaciones cutáneas relacionadas a la infección por el coronavirus SARS-CoV-2, causante de COVID-19, se han descrito entre el 0,2% y 20,4% de las personas que cursan con esta enfermedad. Las más frecuentemente descritas son: lesiones maculopapulares (47%), lesiones acrales eritematosas con vesículas o pústulas (pseudoperniosis) (19%), urticariales (19%), lesiones vesiculosas (9%) y livedo/necrosis (6%). En particular, la pitiriasis rosada es una dermatosis autolimitada de etiología desconocida, sin embargo, se ha visto asociada a la infección por SARS-CoV-2, con algunos reportes de casos en la literatura. El mecanismo fisiopatológico de las lesiones cutáneas en COVID-19 no es claro, y se han planteado algunas teorías, entre las cuales está el papel que juega la enzima convertidora de angiotensina 2 (ACE2) utilizada por el virus para infectar las células, los infiltrados linfocíticos, los depósitos de factores del complemento en la piel, y la reactivación de virus latentes como los herpes virus humanos. Se presenta el caso de una paciente con pitiriasis rosada asociada a COVID-19 y se describen los casos reportados hasta la fecha

Atypical pityriasis rosea in a young colombian woman. case report

ABSTRACT Introduction: Pityriasis rosea is an acute and self-limited exanthem first described by Gilbert in 1860. Its treatment is symptomatic, and although there is no conclusive evidence, it has been associated with the reactivation of the human herpesviruses 6 and 7 (HHV-6 and HHV-7). Case presentation: A 28-year-old woman, from Bogotá, Colombia, a health worker, attended the emergency room due to the onset of symptoms that began 20 days earlier with the appearance of punctiform lesions in the left arm that later spread to the thorax, abdomen, opposite arm, and thighs. The patient reported a history of bipolar II disorder and retinal detachment. After ruling out several infectious diseases, and due to the evolution of the symptoms, pityriasis rosea was suspected. Therefore, treatment was started with deflazacort 30mg for 21 days, obtaining a favorable outcome and improvement of symptoms after 2 months. At the time of writing this case report, the patient had not consulted for recurrence. Conclusion: Primary care physicians should have sufficient training in dermatology to recognize and treat dermatological diseases since many of them are diagnosed based on clinical findings. This is an atypical case, in which the patient did not present with some of the pathognomonic signs associated with pityriasis rosea.

RESUMEN Introducción. La pitiriasis rosada es un exantema agudo y autolimitado que fue descrito formalmente por Gilbert en 1860. Su tratamiento es sintomático y, aunque faltan pruebas concluyentes, su aparición se ha asociado a la reactivación de los herpevirus humanos 7 y 6 (HHV6 y HHV7). Presentación del caso. Mujer de 28 años procedente de Bogotá, Colombia, quien se desempeñaba como trabajadora de la salud y consultó al servicio de urgencias por un cuadro clínico de 20 días de evolución que inició con la aparición de lesiones punteadas en el brazo izquierdo que se expandieron posteriormente a tórax, abdomen, brazo contralateral y muslos. La paciente informó antecedente de trastorno bipolar tipo II y desprendimiento de retina. Después de descartar varias enfermedades infecciosas, y debido a la evolución del cuadro clínico, se sospechó pitiriasis rosada, por lo que se instauró tratamiento con 30mg de deflazacort por 21 días, con el cual se logró una evolución favorable y la mejoría total de los síntomas a los 2 meses. Hasta el momento de la elaboración del presente reporte de caso la joven no había consultado por recurrencia. Conclusión. Es indispensable que los médicos de atención primaria tengan una educación adecuada en dermatología para poder reconocer y tratar la pitiriasis rosada, pues su diagnóstico es eminentemente clínico y puede tener múltiples presentaciones atípicas, como en el caso aquí reportado donde la paciente no tuvo algunos de los signos patognomónicos característicos.

Pericardial effusion associated with DRESS syndrome. Case report / Derrame pericárdico asociado con síndrome de DRESS. Reporte de caso

Abstract Introduction: The DRESS (drug reaction with eosinophilia and systemic symptoms) syndrome is a rare but serious and potentially lethal occurrence of a set of signs and symptoms associated with the use certain types of drugs. This syndrome is characterized by a heterogeneous clinical manifestation that, in many cases, results in multisystemic involvement. Case presentation: A 24-year-old man from Calarcá, Colombia, visited the emergency department of the local hospital due to a three-day history of unquantified intermittent fever associated with asthenia, adynamia, anorexia, headache, myalgia, odynophagia, and upper abdominal pain. Due to his condition and based on laboratory findings, he was referred to the Clínica Central del Quindío. The patient, 20 days before the initial assessment, had been prescribed a pharmacological treatment with non-steroidal anti-inflammatory drugs and phenytoin due to a severe cranioencephalic trauma; he also presented with generalized skin rash, elevated transaminases, and moderate eosinophilia. Complementary studies reported mild pericardial effusion, so DRESS syndrome was suspected, and corticosteroid therapy was started, achieving the complete remission of the syndrome. Conclusion: Although the DRESS syndrome has a low incidence, it should always be suspected, especially in patients with cardiac and pericardial involvement. In this case, pericardial involvement was evident, demonstrating that individuals with this syndrome may present with rare symptoms that have a serious impact on their health, as they may significantly increase adverse outcomes and mortality risk.

Resumen Introducción. El síndrome de DRESS (Drug Reaction with Eosinophilia and Systemic symptoms) consiste en la ocurrencia, si bien poco frecuente, pero grave y potencialmente mortal, de un conjunto de signos y síntomas asociados al consumo de cierto tipo de medicamentos. Este síndrome se caracteriza por tener una manifestación clínica heterogénea que, en muchos casos, causa compromiso multisistémico. Presentación del caso. Hombre de 24 años de Calarcá, Colombia, que asistió al servicio de urgencias del hospital local por presentar fiebre intermitente no cuantificada durante 3 días, junto con astenia, adinamia, anorexia, cefalea, mialgias, odinofagia y dolor abdominal superior, y que, debido a su condición y resultados de laboratorio, fue remitido a la Clínica Central del Quindío. El paciente, 20 días antes de la valoración inicial, había recibido tratamiento farmacológico con antiinflamatorios no esteroides y fenitoína por traumatismo craneoencefálico severo; además presentó rash cutáneo generalizado, elevación de transaminasas y eosinofilia moderada. En los estudios complementarios se reportó derrame pericárdico leve, por lo que se sospechó síndrome de DRESS y se inició corticoterapia, lográndose así la remisión completa de la enfermedad. Conclusión. Aunque el síndrome de DRESS tiene una baja incidencia, siempre debe sospecharse, en especial en pacientes que presentan compromiso cardiaco y pericárdico. En este caso se destaca la afectación pericárdica, demostrando que en este síndrome se pueden presentar ma -nifestaciones poco frecuentes, pero con un gran impacto en su salud, ya que pueden aumentar considerablemente los desenlaces adversos y la mortalidad en estos pacientes.

Síndrome Baboon-like asociado a Parvovirus B19: A propósito de un caso en edad pediátrica / Baboon-like syndrome induced by Parvovirus B19: report of a pediatric case

Resumen El Parvovirus B19 constituye un agente viral frecuente como causa de exantemas en edad pediátrica. Responsable clásicamente del eritema infeccioso, en los últimos años se lo asoció también a erupciones cutáneas atípicas. Recientemente se ha descrito una forma de exantema periflexural asociado a distintos agentes virales, conocido como síndrome Baboon-like. Presentamos el caso de una niña de 9 años con evidencia serológica de infección aguda por Parvovirus 19 que desarrolló una erupción máculo-pápulo-petequial con lesiones acentuadas en grandes pliegues. Se realiza búsqueda de la literatura disponible en relación a los exantemas inusuales por Parvovirus y se describe el caso como síndrome simil Baboon, una manifestación cutánea de esta infección viral.

Abstract Parvovirus B19 is a common viral cause of exanthem in pediatric patients. Classically responsible for infectious erythema, in the last few years it has also been associated with atypical rashes. A form of periflexural eruption associated with viral agents has been recently described as Baboon-like syndrome. We present the case of a 9-years-old girl with serological evidence of acute Parvovirus B19 infection that developed a maculopapular-petechial rash with lesions in large folds. A review of the available literature in relation to unusual Parvovirus exanthem is performed and the case is described as Baboon - like syndrome, a cutaneous manifestation of this viral infection.

Síndrome de reacción a fármacos con eosinofilia y síntomas sistémicos inducido por carbamazepina de liberación prolongada: reporte de un caso

El síndrome de reacción a fármacos con eosinofilia y síntomas sistémicos es una reacción de hipersensibilidad a fármacos poco común, pero con una alta mortalidad, por ello se requiere un diagnóstico precoz y un manejo oportuno. Presentamos el caso de una mujer de 32 años con diagnóstico de epilepsia y trastorno esquizofreniforme orgánico, secundarios a encefalitis viral, y que ha recibido tratamiento con múltiples fármacos. Tres semanas después de añadir carbamazepina de liberación prolongada a su terapia habitual, la paciente presentó una erupción cutánea difusa tipo habón, edema facial, fiebre, linfadenopatía, leucocitosis con eosinofilia y elevación de las transaminasas. La administración de la carbamazepina fue suspendida, se administró antihistamínicos y glucocorticoides por vía oral, y la paciente mejoró.

The drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome is a rare but highly lethal drug hypersensitivity reaction. Thus, it requires an early diagnosis and timely management. We present the case of a 32-year-old female patient with a diagnosis of epilepsy and organic schizophreniform disorder, secondary to viral encephalitis, who was treated with multiple drugs. Three weeks after the addition of extended-release carbamazepine to her usual therapy, the patient presented a diffuse welt-type skin rash, facial edema, fever, lymphadenopathy, leukocytosis with eosinophilia and elevated transaminases. Carbamazepine administration was discontinued, antihistamines and glucocorticoids were administered orally, and the patient showed a remarkable improvement.

Síndrome DRESS asociado a fenitoína: informe de caso / DRESS syndrome associated with phenytoin: case report

El síndrome DRESS es una reacción adversa dermatológica que puede presentarse debido a diversos medicamentos, y constituye uno de los diagnósticos más importantes por encima del síndrome de Stevens-Johnson. Se trata de un caso relacionado con una reacción adversa de muy baja frecuencia, que está documentada en la literatura científica, a varios medicamentos, entre ellos la fenitoína. Por lo mencionado, la publicación de estos casos resulta escasa y limitada. Las principales preocupaciones del paciente relacionadas con su cuadro clínico radicaban en el gran compromiso cutáneo que lo llevó a hospitalización, dolor e incomodidad, por el cual recurrió al manejo tópico generalizado con vaselina. Los hallazgos clínicos relevantes fueron: eosinofilia severa, ulceraciones cutáneas, hepatitis química y fiebre. Con los hallazgos del cuadro clínico y la evaluación de la escala RegiSCAR se hace el diagnóstico de síndrome DRESS inducido por fenitoína. Se suspende la fenitoína, se inicia levetiracetam y se administran corticosteroides y acetaminofén con evolución favorable. (AU)

DRESS syndrome is a dermatological adverse reaction can occur due to various medications, being one of the most important diagnoses above Steven-Johnson syndrome. This is a case related to a very low frequency adverse reaction that is documented in the scientific literature to several medicines among those, the phenytoin. Therefore, the publication of these cases is scarce and limited. The main concerns of the patients related to their clinical picture were due to the great cutaneous compromise that lead to hospitalization, pain and discomfort for which they resorted to generalized topical management with vaseline (petrolatum). Relevant clinical findings were severe eosinophilia, skin ulcerations, chemical hepatitis and fever. With clinical picture findings and evaluation of the RegiSCAR scale, the diagnosis of Phenytoin-induced DRESS syndrome is made. Phenytoin is discontinued, levetiracetam is started and corticosteroids and acetaminophen are administrated with favorable evolution. (AU)

Síndrome de GianottiCrosti:diagnóstico a considerar en pacientes pediátricos con exantemas acrales / Gianotti Crosti syndrome: a diagnosis to consider in pediatric patients with acral exanthema

Resumen Los exantemas virales en la infancia,son motivo deconsulta frecuente, en los Servicios de Dermatología, Pediatría, y Urgencias. Usualmente, son autolimitados y pueden ser difíciles de diagnosticar. Es importante reconocerlos y diferenciarlos de otras enfermedades severas que requieran un tratamiento inmediato. El síndrome de Gianotti-Crosti, también conocido como acrodermatitispapulosa de la infancia, es un exantema poco frecuente, secundario a la respuesta inmune del huésped frente a infecciones, especialmente virales o luego de inmunizaciones. La primera asociación descrita fue con la infección por el virus de hepatitis B, sin embargo, con la introducción de la vacuna contra este virus, aumentó la incidencia de otros virus relacionados con este síndrome. Presentamos el caso de un paciente de 4 años de edad con diagnóstico clínico de síndrome de Gianotti-Crosti.

Abstract Viralexanthemsin childhood are a frequent consultation both outpatient and in emergency services. They are usually self-limited and can be difficult to diagnose. It's important to recognize and differentiate them from other severe diseases that require immediate treatment. GianottiCrosti syndrome, also known as papularacrodermatitis of childhood, is an infrequent exanthema secondary to the host's immune response to infections, especially viral, or vaccines. The first association described was with hepatitis B virus infection, however, with the introduction of the vaccine against this virus,the incidence of other viruses related to this syndrome has increased. We present the case of a 4-year-old patient with a clinical diagnosis of GianottiCrosti syndrome.

Cutaneous manifestations in a patient with COVID-19 treated at a hospital in the Peruvian jungle. A case report / Manifestaciones cutáneas en un paciente con COVID-19 atendido en un hospital de la selva peruana. Reporte de un caso

Abstract Introduction: Most patients infected with the coronavirus disease 2019 (COVID-19) experience mild to moderate symptoms. This condition may affect multiple organs and systems, including the skin, and cutaneous manifestations are varied. Although several studies on COVID-19 have been conducted in Peru, to date, this type of manifestation has not been described in the Peruvian population, especially in environments with high prevalence of viral diseases that cause similar dermatological lesions, such as the Peruvian jungle. Case presentation: A 16-year-old male patient with no relevant medical history was admitted to a hospital in the Peruvian jungle due to headache, chills, general malaise, and respiratory distress. On physical examination, oxygen saturation was 89-90%, and a skin rash was observed; it was characterized by non-evanescent, confluent, pruritic, and symmetrical morbilliform lesions in the limbs, abdomen, thorax, and face, without mucous membrane involvement. Due to the shortage of molecular tests in the region where he was treated, he was diagnosed with COVID-19 based on serological (serological tests for SARS-CoV-2 (IgM+ and IgG+)) and radiological criteria (imaging findings compatible with COVID-19 atypical pneumonia). The initial treatment included the administration of ceftriaxone, azithromycin, dexamethasone, cetirizine, as well as the use of oxygen by binasal cannula. After 5 days and given the persistence of symptoms and respiratory and skin signs, treatment with ivermectin was started. 48 hours after the introduction of this treatment, the cutaneous and respiratory manifestations had completely resolved. Conclusions: Patients with COVID-19 may develop several cutaneous manifestations similar to those produced by other viruses or adverse drug reactions. Therefore, it is necessary to appropriately interview the patient and establish the chronological order of symptom onset to diagnose this disease correctly.

Resumen Introducción. La mayoría de los pacientes con COVID-19 experimentan síntomas leves a moderados. Esta enfermedad puede afectar varios órganos y sistemas, entre ellos la piel, siendo las manifestaciones cutáneas muy variadas. A pesar de que en Perú existen varios estudios sobre COVID-19, a la fecha este tipo de manifestaciones no se han descrito en población peruana, lo cual llama la atención debido a que en el país existen varias zonas donde coexisten enfermedades virales que producen lesiones dermatológicas similares, tales como la selva peruana. Presentación del caso. Varón de 16 años sin antecedentes médicos relevantes quien ingresó a un hospital de la selva peruana con cefalea, sensación distérmica y dificultad respiratoria. Al examen físico, el paciente presentó una saturación de oxígeno de 89-90% y se observó erupción cutánea caracterizada por lesiones morbiliformes no evanescentes, confluentes, pruriginosas y simétricas en extremidades, abdomen, tórax y cara, sin compromiso de mucosas. Debido a la escasez de pruebas moleculares en la región donde fue atendido, al paciente se le realizó el diagnóstico de COVID-19 con base en criterios serológicos (pruebas serológicas para SARS-CoV-2 (IgM+ e IgG+)) y radiológicos (hallazgos de imagen compatibles con neumonía atípica por COVID-19). El manejo inicial incluyó la administración de ceftriaxona, azitromicina, dexametasona y cetirizina, así como el uso de oxígeno por cánula binasal. Después de 5 días, y ante la persistencia de los síntomas y signos respiratorios y cutáneos, se inició tratamiento con ivermectina; 48 horas después de haber instaurado este tratamiento se evidenció la resolución completa de las manifestaciones cutáneas y respiratorias. Conclusiones. Los pacientes con COVID-19 pueden desarrollar manifestaciones cutáneas similares a las producidas por otros virus o por reacciones adversas a medicamentos; por lo tanto, para realizar un diagnóstico apropiado de la enfermedad, es necesario hacer una adecuada entrevista al paciente y establecer el orden cronológico de aparición de los síntomas.
