Objectives: To estimate burnout prevalence among pediatric residents and to evaluate the impact of a brief intervention aimed at controlling burnout. Methods:A randomized controlled trial was conducted on 74 pediatric residents. The Maslach Burnout Inventory was administered to all subjects, and demographic information was gathered (age, gender, children, cohabitants, and residency year). The experimental group (n = 37) participated in self-care workshops over the course of 2 months, and the control group (n = 37) did not receive any intervention. After the intervention, the Maslach Burnout Inventory was administered again to all participants. All potential predictors of burnout were included in a logistic regression model. The efficacy of the intervention was evaluated by the chi-square test. P values < 0.05 were considered significant. Results:The burnout prevalence among pediatric residents was 66%. After controlling for age, gender, children, and cohabitants, the prevalence of burnout was significantly higher among third-year residents (odds ratio = 11.8; 95% confidence interval 2.3-59.3; p = 0.003). There were no significant differences regarding burnout prevalence in the experimental group between the baseline and post-intervention periods (p = 0.8) or between the two groups after intervention (p = 0.8). The only difference observed was an improvement regarding "depersonalization" in the experimental group (p = 0.031). Conclusions:The burnout prevalence among pediatric residents was 66% and was higher among third-year residents. A brief intervention was not effective in reducing burnout prevalence, despite the achievement of an improvement in "depersonalization."J Pediatr (Rio J). 2011;87(6):493-8: Burnout, professional Resultados: A prevalência de burnout entre residentes pediátricos foi de 66%. Após controle para idade, gênero, filhos e coabitantes, a prevalência de burnout foi maior entre residentes do terceiro ano (razão de chances = 11,8; intervalo de confiança de 95% 2,3-59,3; p = 0,003). Não foram encontradas diferenças significativas na prevalência de burnout no grupo experimental entre os períodos inicial e pós-intervenção (p = 0,8) ou entre os dois grupos após a intervenção (p = 0,8). A única diferença observada foi uma melhora quanto à "despersonalização", no grupo experimental (p = 0,031). Conclusões:A prevalência de burnout entre residentes pediátri-cos foi de 66%, sendo maior entre os residentes do terceiro ano. Uma intervenção breve não foi eficaz na redução da prevalência de burnout, apesar da melhora no quesito "despersonalização".J Pediatr (Rio J). 2011;87(6):493-8: Burnout, internato e residência, qualidade de vida. Impact of a brief intervention on the burnout levels of pediatric residents IntroduçãoA síndrome de burnout foi definida como uma resposta negativa ao estresse interpessoal e emocional crônico no ambiente de trabalho, caracterizado por exaustão física, emocional e mental em decorrência da exposição do indivíduo a situações emocionalmente exigentes durante um longo p...

Aim This case report demonstrates a positive outcome of the adjuvant use of fragile fracture (FF), which is a technique used to harvest dental pulp stem cells (DPSCs), and platelet‐rich plasma (PRP) in a mandibular premolar (tooth 44) with a completely formed root that was transplanted into a surgically created socket and which maintained pulp vitality and function. Summary After virtual surgical planning, a 3D tooth replica of tooth 44 was fabricated. A surgical socket was created in the position of tooth 14; then, tooth 44 was extracted and the root dentine was abraded using a turbine diamond bur 3 mm from the apex until a circular groove was prepared around the outer circumference of the root; and then, an FF was performed without damaging the pulp tissue. PRP was placed in the socket, after which the donor tooth was inserted in the recipient area. At 2 weeks post‐treatment, orthodontic traction was applied. At 3‐year follow‐up, the tooth had adequate alignment and was asymptomatic. Response to pulp testing was positive, and the presence of pulp canal obliteration was observed as a sign of pulpal healing. Key learning points Autotransplantation is a good alternative for replacing missing teeth, with repair of tissues and pulp revascularization. Revascularization of an autotransplanted mature tooth using the fragile fracture technique and PRP scaffold is a feasible option and might have positive effects on the long‐term outcome of the procedure. Including completely formed teeth as donors in autotransplantation, maintaining vitality and their functions is an option that warrants further study.

Background: Although there are reports on COVID-19 in pediatrics, it is possible that the characteristics of each population, their health systems and how they faced the pandemic made the disease show distinctive features in different countries. We aimed to describe the characteristics of patients hospitalized for COVID-19 in a tertiary pediatric hospital in the City of Buenos Aires, Argentina. Methods: Descriptive study, including all patients hospitalized for COVID-19 in a tertiary pediatric hospital, from 04/26/2020 to 10/31/2020. Demographic, clinical and epidemiological characteristics of the patients are described. Results: In the studied period 578 children and adolescents were hospitalized for COVID-19. The median age was 4.2 years and 83% had a history of close contact with a confirmed COVID-19 case. Regarding severity, 30.8% were asymptomatic, 60.4% mild, 7.4% moderate, and 1.4% severe. Among those with symptoms, the most frequent was fever, followed by sore throat and cough. Conclusion: We reported 578 cases of children and adolescents hospitalized for COVID-19, most of them showed a mild or asymptomatic condition.

The use of the BPS allowed to reduce antibiotic use in the initial management of patients with pneumonia vaccinated against pneumococcal disease, without increasing the probability of an unfavorable course of the disease.

Introducción: Debido a ambigüedades en la nomenclatura, las infecciones respiratorias agudas bajas (IRAB) en la infancia frecuentemente no son debidamente registradas, especialmente durante las consultas ambulatorias. Contar con una herramienta que las identifique con precisión, permitirá evaluar el impacto en la salud respiratoria de noxas de alcance masivo y diseñar las políticas para prevenirlas o mitigar sus efectos. Nuestro objetivo fue construir un algoritmo que permita identificar niños con IRAB a partir de los datos de la historia clínica electrónica (HCE) del Gobierno de la Ciudad de Buenos Aires (GCBA). Métodos: Utilizando la HCE-GCBA, se seleccionaron aleatoriamente 1000 consultas ambulatorias de pacientes menores de 2 años. Se buscaron términos que hicieran referencia a que la consulta era motivada por IRAB, con los que se desarrolló un algoritmo basado en reglas duras. Se utilizó otro set de datos de 800 consultas para ajustar el algoritmo y, finalmente, se validó su desempeño en un tercer set de 800 consultas correspondientes a todo el año 2018. Resultados: En el set de validación, la herramienta desarrollada identificó IRAB con sensibilidad 88,24%, especificidad 97,5%, VPP 86,07% y VPN 97,93%. Conclusión: El algoritmo de búsqueda desarrollado permite identificar con aceptable precisión las consultas ambulatorias relacionadas con IRAB en niños menores de 2 años.
