Dengue en paciente de 32 días de vida. Reporte de un caso poco habitual / Dengue fever in a 32-day-old patient. A rare case report

El dengue es una enfermedad viral transmitida por la picadura del mosquito Aedes aegypti. El comportamiento del dengue en Argentina es epidémico; la mayoría de los casos se observan en los meses de mayor temperatura. Hasta la semana epidemiológica (SE) 20/2023, se registraron en Argentina 106 672 casos; se vieron afectadas 18 de las 24 provincias que conforman el país. Dentro de los principales grupos de riesgo, se incluyen los menores de 2 años. Reconocer los signos, síntomas e identificar los factores de riesgo es fundamental para el manejo de casos con mayor riesgo de gravedad. Presentamos el caso de una paciente de 32 días de vida que se internó por síndrome febril sin foco, con diagnósticos diferenciales de meningitis viral y sepsis, evolucionó con leucocitosis, plaquetopenia, hipoalbuminemia, asociado a exantema y edemas. Se llegó al diagnóstico de dengue por la clínica, epidemiologia e IgM positiva.

Dengue fever is a viral disease transmitted by the Aedes aegypti mosquitoes. In Argentina, dengue fever is an epidemic disease; most cases are reported during the hot months.Until epidemiological week (EW) 20/2023, 106 672 cases were reported across 18 of the 24 provinces of Argentina. Children younger than 2 years are among the main groups at risk. Recognizing signs and symptoms and identifying risk factors is fundamental for the management of cases at a higher risk of severity. Here we describe the case of a 32-day-old female patient who was hospitalized due to febrile syndrome without a source, who had a differential diagnosis of viral meningitis and sepsis and progressed to leukocytosis, thrombocytopenia, hypoalbuminemia in association with rash and edema. The diagnosis of dengue fever was established based on clinical, epidemiological, and positive IgM data.

Relationship between sacroiliitis and inflammatory markers in familial Mediterranean fever

SUMMARY OBJECTIVE: Familial Mediterranean fever is the most common monogenic autoinflammatory disease. This study aimed to evaluate the relationship between sacroiliitis observed in familial Mediterranean fever and hematological inflammatory markers. METHODS: In this study, 168 familial Mediterranean fever patients were examined. A total of 61 familial Mediterranean fever patients who had sacroiliac magnetic resonance imaging due to waist and hip pain were included in the study. According to the magnetic resonance imaging findings, patients were divided into two groups: with and without sacroiliitis. The relationship between hematological inflammatory markers and sacroiliitis was investigated. RESULTS: The frequency of sacroiliitis was found to be 13.6% in all familial Mediterranean fever patients and 37.8% in patients with low back pain who underwent sacroiliac magnetic resonance imaging. Neutrophil count, neutrophil/lymphocyte ratio, monocyte/lymphocyte ratio, and systemic immune-inflammatory index were significantly higher in the sacroiliitis group than in the other group, and this difference was found to be statistically significant (p<0.05). As a result of the receiver operating characteristic analysis, it was observed that neutrophil/lymphocyte ratio, monocyte/lymphocyte ratio, and systemic immune-inflammatory index were very sensitive parameters in determining sacroiliitis in patients with familial Mediterranean fever. CONCLUSION: It was observed that the frequency of sacroiliitis was increased in familial Mediterranean fever patients. It is predicted that hematological inflammatory markers such as neutrophil/lymphocyte ratio, monocyte/lymphocyte ratio, and systemic immune-inflammatory index can be used in the diagnosis of sacroiliitis.

Estimated annual costs of Chikungunya fever in the municipality of Rio de Janeiro, Brazil / Estimativa dos custos anuais da febre chikungunya no município do Rio de Janeiro

ABSTRACT Objective: To estimate the cost of illness of Chikungunya in the municipality of Rio de Janeiro, Brazil, in 2019. Methods: The study is a partial economic evaluation carried out with secondary data with free and unrestricted access. Direct outpatient and indirect costs of the acute, post-acute, and chronic phases of Chikungunya fever were estimated, in addition to hospital costs. The estimate of direct costs was performed using the notified cases and the standard treatment flowchart in the state of Rio de Janeiro. The indirect ones consist of loss of productivity and disability, using the burden of disease indicator (Disability-adjusted life year - DALY). Results: The total number of reported cases was 38,830. Total costs were calculated at BRL 279,807,318, with 97% related to indirect costs. Conclusion: The chronic phase and indirect costs were the most expensive. The inability and permanence of Chikungunya differentiate the disease and increase the costs of its treatment.

A estimativa dos custos diretos foi realizada através dos casos notificados e do fluxograma padrão de tratamento do estado do Rio de Janeiro. Os indiretos consistem na perda de produtividade e da incapacidade, utilizando o indicador de carga de doença (DALY). Resultados: O número total de casos notificados foi de 38.830. Os custos totais foram calculados em R$ 279.807.318, sendo 97% relacionados aos custos indiretos. Conclusão: A fase crônica e os custos indiretos foram os mais onerosos. A incapacidade e a permanência da chikungunya diferenciam a doença e aumentam os custos de seu tratamento.

Estado reaccional de enfermedad de Hansen como causa de fiebre de origen desconocido

Los fenómenos reaccionales de la lepra son complicaciones inflamatorias que a menudo se presentan como verdaderas emergencias médicas durante el curso del tratamiento o incluso después de culminarlo. A menudo, los síntomas sistémicos como la fiebre pueden aparecer antes que las manifestaciones cutáneas y desconcertar al médico. Se realiza la presentación del caso de un paciente masculino, 39 años, sano, que acude con cuadro de 2 meses de evolución de fiebre, pérdida de peso, con posterior aparición de manchas rojas en todo el cuerpo. Se realizaron biopsia de piel y baciloscopia, con los cuales se pudieron llegar al diagnóstico de lepra.

The reactional phenomena of leprosy are inflammatory complications that often present as true medical emergencies during treatment or even after completion. Often, systemic symptoms such as fever can appear before skin manifestations and baffle the doctor. The case presented is a 39-year male patient, healthy, who consult with a 2-month history of fever, and weight loss, with subsequent appearance of red spots all over the body. A skin biopsy and smear microscopy were performed, with which leprosy was diagnosed.

Egg allergy and yellow fever vaccination

Abstract Objective Evaluate biomarkers capable of safely guiding Yellow fever vaccine (YFV) vaccination among individuals suspicious of hen's egg allergy, and identify factors associated with a higher risk for adverse events after immunization (AEAI). Methods Patients underwent skin prick test (SPT) for standardized allergens: whole egg, egg white, egg yolk; YFV (1:10 dilution; Biomanguinhos-Fiocruz), and intradermal test (IDT; YFV 0.02 mL, 1:100 dilution) and positive and negative controls. Serum levels of specific IgE (sIgE) for a whole egg, egg white, egg yolk, egg albumin, ovomucoid, lysozyme, and conalbumin (ImmunoCap®; ThermoFisher®) were obtained. Patients sensitized to YFV were submitted to YFV desensitization, and those negatives received YFV (0.5mL) and remained under surveillance for at least one hour. Results 103 patients were enrolled, 95% under 12 years old. 71% (81/103) of patients had reactions: 80% immediate, 11% mixed, and 9% delayed. There was an association between positive skin test results with YFV and the severity of the reaction (OR:7.64; 95%CI:1.61-36.32; p =0,011). Only the presence of sIgE to ovomucoid was associated with clinical symptoms (p =0,025). Thirty patients underwent the YFV desensitization protocol. Conclusion There is a relationship between the positivity of the egg's components and the severity of the clinical reaction. Furthermore, the relationship between the positivity of the tests with the YFV and egg's components may show a tendency to look at ovomucoid and conalbumin, but it is not a certainty. Therefore, further studies are needed to confirm these associations, and for now, the authors still recommend using the vaccine for testing when necessary.

When the fever will not stop, stop the pills! A case report

ABSTRACT Neuroleptic malignant syndrome (NMS) is a neurologic emergency potentially fatal. This rare side effect is most commonly associated with first-generation antipsychotics and less frequently with atypical or second-generation antipsychotics. The diagnosis relies on both clinical and laboratory criteria, with other organic and psychiatric conditions being ruled out. CASE REPORT: A 39-year-old female patient, who is institutionalized and completely dependent, has a medical history of recurrent urinary infections and colonization by carbapenem-resistant Klebsiella pneumoniae. Her regular medication regimen included sertraline, valproic acid, quetiapine, risperidone, lorazepam, diazepam, haloperidol, baclofen, and fentanyl. The patient began experiencing dyspnea. Upon physical examination, she exhibited hypotension and a diminished vesicular murmur at the right base during pulmonary auscultation. Initially, after hospitalization, she developed high febrile peaks associated with hemodynamic instability, prompting the initiation of antibiotic treatment. Despite this, her fever persisted without an increase in blood inflammatory parameters, and she developed purulent sputum, necessitating antibiotherapy escalation. The seventh day of hospitalization showed no improvement in symptoms, suggesting NNMS as a differential diagnosis. All antipsychotic and sedative drugs, as well as antibiotherapy, were discontinued, after which the patient showed significant clinical improvement. CONCLUSION: Antipsychotic agents are commonly employed to manage behavioral changes linked to various disorders. However, their severe side effects necessitate a high degree of vigilance, the cessation of all medications, and the implementation of supportive care measures. A prompt and accurate diagnosis of NMS is crucial to alleviating the severe, prolonged morbidity and potential mortality associated with this syndrome.

Percepções da dengue na perspectiva de uma comunidade rural da costa caribenha na Colômbia / Perceptions of dengue fever from the perspective of a rural community on the Caribbean coast in Colombia / Percepciones del dengue desde la perspectiva de una comunidad rural de la costa Caribe en Colombia

O estudo buscou compreender as percepções sobre a dengue em uma comunidade rural de Córdoba, Colômbia, com o objetivo de orientar ações específicas de enfermagem comunitária voltadas para o cuidado e a educação em saúde de pessoas, famílias e comunidades rurais. Foram realizadas 20 entrevistas semiestruturadas com chefes de família (13 homens e 7 mulheres), selecionados com base nos critérios de serem membros da comunidade há mais de 20 anos, se autoidentificarem como camponeses e terem no mínimo 18 anos de idade. O número de participantes foi determinado após alcançar a saturação teórica. As entrevistas foram transcritas e organizadas em uma matriz de análise para codificação, categorização e análise dos dados. Os achados revelaram três categorias analíticas: busca pelo conhecimento sobre a doença, práticas in situ e cuidados do passado e do presente. As famílias entrevistadas possuem conhecimento básico sobre a doença e o vetor causador, mantendo práticas familiares relacionadas ao uso de plantas medicinais para cuidados familiares e automedicação nas fases iniciais, devido à baixa percepção do risco. As famílias camponesas constroem representações socioculturais baseadas em solidariedade, apoio familiar e respeito pelo conhecimento dos idosos. A enfermagem é apresentada como ator essencial na coleta de práticas de cuidado para a elaboração e aplicação de planos de cuidado contextualizados de acordo com as necessidades do território. A pesquisa foi aprovada com o código SI-FCS-02-22, autorizando sua implementação.

The study sought to understand perceptions about dengue fever in a rural community in Córdoba, Colombia, with the aim of guiding specific community nursing actions aimed at health care and education for people, families and rural communities. 20 semi-structured interviews were carried out with heads of families (13 men and 7 women), selected based on the criteria of being members of the community for more than 20 years, self-identifying as peasants and being at least 18 years of age. The number of participants was determined after reaching theoretical saturation. The interviews were transcribed and organized into an analysis matrix for coding, categorization and data analysis. The findings revealed three analytical categories: search for knowledge about the disease, in situ practices and past and present care. The families interviewed have basic knowledge about the disease and the causative vector, maintaining family practices related to the use of medicinal plants for family care and self-medication in the early stages, due to low risk perception. Peasant families build sociocultural representations based on solidarity, family support and respect for the knowledge of the elderly. Nursing is presented as an essential actor in the collection of care practices for the elaboration and application of care plans contextualized according to the needs of the territory. The research was approved with code SI-FCS-02-22, authorizing its implementation.

Autoinflammatory diseases: a Latin American multicenter study according to age and sex / Doenças autoinflamatórias: um estudo multicêntrico latino-americano de acordo com o sexo e a idade

ABSTRACT Objective: To evaluate autoinflammatory diseases (AID) according to age at diagnosis and sex, and response to therapy in a large population. Methods: This is a cross-sectional observational study of a Latin American registry using a designed web system for data storage, collected between 2015 and 2018. Any altered findings during follow-up were recorded. The forms were translated into Portuguese and Spanish, including demographic, clinical, laboratory, genetic and treatment characteristics. Results: We included 152 patients, 51.3% male and 75% Caucasian. The median age at disease onset was 2.1 years (0-15.6 years) and median age at diagnosis 6.9 years (0-21.9 years); 111 (73%) were children (0-9 years old), and 41 (27%) were adolescents and young adults (AYA) (10-21 years old). Periodic fever, aphthous stomatitis, pharyngitis, and adenitis syndrome (PFAPA) occurred in 46/152 (30%), chronic non-bacterial osteomyelitis (CNO) in 32/152 (21%), and familial Mediterranean fever (FMF) in 24/152 (15.7%). PFAPA was significantly higher in young children than in AYA (38.7% vs. 7.3%, p<0.001), while CNO were lower (13.5% vs. 41.5%, p<0.001). The frequency of females was significantly higher in CNO (28.4% vs. 14.1%, p=0.031) and lower in FMF (8.1% vs. 23.1%, p=0.011). The most used drugs were glucocorticoids, non-steroidal anti-inflammatory drugs (NSAID), and colchicine. Glucocorticoids and colchicine treatment were used in all AID with good to moderate response. However, cryopyrin-associated periodic syndromes (CAPS) seemed unresponsive to glucocorticoids. NSAIDs and methotrexate were the main medications used to treat CNO. Conclusions: Differences among AID patients were observed in the LA population regarding sex and age at disease diagnosis.

RESUMO Objetivo: Avaliar as doenças autoinflamatórias (DAI) de acordo com sexo e idade no momento do diagnóstico e a resposta terapêutica em uma grande população. Métodos: Este é um estudo observacional transversal de um registro latino-americano que usou um sistema de dados coletados entre 2015 e 2018. Quaisquer achados alterados ao longo do acompanhamento foram registrados. Os formulários foram traduzidos para os idiomas português e espanhol, incluindo características demográficas, clínicas, laboratoriais, genéticas e de tratamento. Resultados: Incluímos 152 pacientes, sendo 51,3% do sexo masculino e 75% da raça branca. A média de idade de início da doença foi de 2,1 anos (0-15,6 anos) e a média de idade de diagnóstico 6,9 anos (0-21,9 anos); 111 (73%) eram crianças (0-9 anos) e 41 (27%) adolescentes/adultos jovens (10-21 anos). A síndrome de febre periódica, estomatite aftosa, faringite e adenite (PFAPA) ocorreu em 46/152 (30%), osteomielite não bacteriana crônica (CNO) em 32/152 (21%) e febre familiar do Mediterrâneo (FMF) em 24/152 (15,7%). A PFAPA foi significativamente maior em crianças pequenas (38,7 vs. 7,3%, p<0,001), e a CNO, em adolescentes/adultos jovens (13,5 vs. 41,5%, p<0,001). A frequência do sexo feminino foi significativamente maior na CNO (28,4 vs. 14,1%, p=0,031) e menor na FMF (8,1 vs. 23,1%, p=0,011). Os medicamentos mais utilizados foram glicocorticoides, anti-inflamatórios não esteroidais (AINE) e colchicina. O tratamento com glicocorticoides e colchicina foi usado em todas as DAI com resposta boa a moderada. No entanto, as síndromes periódicas associadas à criopirina (CAPS) pareciam não responder aos glicocorticoides. AINE e metotrexato foram os principais medicamentos utilizados no tratamento da CNO. Conclusões: Diferenças de pacientes com DAI foram observadas na população latino-americana em pacientes agrupados por sexo e idade ao diagnóstico da doença.

Safety of the yellow fever vaccine in people living with HIV: a longitudinal study exploring post-vaccination viremia and hematological and liver kinetics

ABSTRACT Background: Safety data on the yellow fever vaccine 17DD in People Living with HIV (PLWH) are limited. This study explored the occurrence of post-vaccination 17DD viremia and the kinetics of hematological and liver laboratorial parameters in PLWH and HIV-uninfected participants [HIV(-) controls]. Methods: We conducted a secondary analysis of a longitudinal interventional trial (NCT03132311) study that enrolled PLWH and HIV(-) controls to receive a single 17DD dose and were followed at 5, 30 and 365 days after vaccination in Rio de Janeiro, Brazil. 17DD viremia (obtained throughreal-time PCR and plaque forming units' assays), hematological (neutrophils, lymphocytes and platelets counts) and liver enzymes (ALT and AST) results were assessed at baseline and Days 5 and 30 post-vaccination. Logistic regression models explored factors associated with the odds of having positive 17DD viremia. Linear regression models explored variables associated with hematological and liver enzymes results at Day 5. Results: A total of 202 PLWH with CD4 > 200 cells/μL and 68 HIV(-) controls were included in the analyses. 17DD viremia was found in 20.0 % of the participants and was twice more frequent in PLWH than in HIV(-) controls (22.8% vs. 11.8 %, p-value < 0.001). Neutrophils, lymphocytes and platelets counts dropped at Day 5 and returned to baseline values at Day 30. 17DD viremia was associated with lower nadir of lymphocytes and platelets at Day 5. ALT levels did not increase post-vaccination and were not associated with 17DD viremia. Conclusions: 17DD was safe and well-tolerated in PLWH with CD4 > 200 cells/μL. Post-vaccination viremia was more frequent in PLWH than in controls. Transient and self-limited decreases in lymphocytes and neutrophils occurred early after vaccination. 17DD viremia was associated with lower lymphocytes and platelets nadir after vaccination. We did not observe elevations in ALT after 17DD vaccination.

Rickettsia rickettsii and Rickettsia typhi in hospitalized children diagnosed with Pediatric Multisystemic Inflammatory Syndrome in Merida, Yucatan

Abstract Multisystem Inflammatory Syndrome in Children (MIS-C) presents with fever, fatigue, elevated inflammatory markers (acute phase reactants), and a history of exposure to SARS-CoV-2 or positive antibodies to SARS-CoV-2. As the COVID-19 pandemic unfolded, the risk of MIS-C in the pediatric population increased. However, exposure to other viruses and the presence of SARS-CoV-2 positive antibodies in children hospitalized for various pathogen-associated illnesses will also remain common and may complicate differential diagnoses with diseases endemic to the region such as rickettsial diseases. The objective was to highlight the desirability of medical personnel systematically incorporating rickettsiosis as a differential diagnosis for MIS-C when studying a child with fever, non-specific symptoms, and elevated inflammatory markers. In conclusion MIS-C should be considered in children with elevated inflammatory markers when there is a history of COVID-19 and they also meet criteria that have already been established by international agencies, such as CDC and WHO

Neurological manifestation of Brazilian spotted fever in childhood

ABSTRACT Rocky Mountain Spotted Fever is a rickettsial disease caused by the bacteria Rickettsia rickettsii. In Brazil, the disease is known as Brazilian spotted fever (BSF), being the most significant tick-borne disease in the country. Among the affected patients, only 5% of cases occur in children aged one to nine years. Typical symptoms of the disease are fever, rash, headache and digestive symptoms. Neurological manifestations such as seizures, aphasia and hemiparesis have been described in few patients. This study aimed to describe the case of an infant diagnosed with BSF who presented severe signs of neurological manifestation.

Manejo não farmacológico da enfermagem em pacientes pediátricos com febre e hipertermia: uma revisão sistemática / Non-pharmacological nursing management of pediatric patients with fever and hyperthermia: a systematic review / Manejo de enfermería no farmacológico del paciente pediátrico con fiebre e hipertermia: una revisión sistemática

Objetivo: descrever o manejo não farmacológico do enfermeiro frente ao paciente pediátrico com febre ou hipertermia. Método: a revisão seguiu o PRISMA, contou com estudos empíricos, que abordassem o manejo não farmacológico em crianças com febre, estudos entre 2013 e 2023. As bases de dados foram Adolec, BVS, Embase, LILACS, Web of Science e a biblioteca SciELO, com os descritores "criança", "hipertermia", "febre", "enfermagem" e "enfermagem pediátrica". Resultados: selecionado 7 estudos, descrevem que o manejo não farmacológico são massoterapia, compressas, água morna e sabonete com Marshmallow. O uso de antitérmico (paracetamol) e outra medida não farmacológico foi evidenciada como efetiva. Há lacuna de protocolos para guiar os profissionais para o atendimento da criança com febre, além dos profissionais se basearem em suas crenças na assistência. Conclusão: o uso não farmacológico foi eficaz em conjunto com antitérmico. Há necessidade de outros estudos e desenvolvimento de protocolos para guiar os profissionais na assistência.

Objective: to describe the nurse's non-pharmacological management of pediatric patients with fever or hyperthermia. Method: the review followed PRISMA and included empirical studies that addressed non-pharmacological management in children with fever, studies between 2013 and 2023. The databases were Adolec, BVS, Embase, LILACS, Web of Science and the SciELO library, with the descriptors "child", "hyperthermia", "fever", "nursing" and "pediatric nursing". Results: 7 studies were selected, describing non-pharmacological management as massage therapy, compresses, warm water, and soap with Marshmallow. The use of antipyretics (paracetamol) and other non-pharmacological measures were shown to be effective. There is a lack of protocols to guide professionals in caring for children with fever, in addition to professionals relying on their beliefs in care. Conclusion:non-pharmacological use was effective in conjunction with antipyretics. There is a need for further studies and development of protocols to guide professionals in helping.
