RESUMEN
Neurologic complications have been associated with multisystem inflammatory syndrome in children, possibly involving autoimmune mechanisms. Here, we report a 6-year-old girl who developed myasthenia 11 weeks after severe acute respiratory syndrome coronavirus 2 infection and 8 weeks after the onset of severe multisystem inflammatory syndrome in children.

Multiple-drug-resistant enterococcal infections canbe a serious problem in pediatric patients particularly concomitance with severe underlying diseases and lead to significant morbidity and mortality. The treatment options in children are limited compared with adults. We report a 3-year old-boy with acute myeloid leukemia (AML)-M7 and vancomycin-resistant enterococcus bacteremia successfully treated with daptomycin. Daptomycin may be an alternative therapy for VRE infections in children; more studies are needed for extended usage.
Las infecciones enterocócicas multirresistentes pueden ser un problema serio en los pacientes pediátricos y causarles complicaciones importantes o la muerte, en particular, en los casos de enfermedades subyacentes graves concomitantes. Las opciones de tratamiento en los niños son limitadas en comparación con las de los adultos. En este artículo, presentamos el caso de un niño de 3 años con leucemia mieloide aguda (LMA)-M7 y bacteriemia por Enterococcus resistente a la vancomicina, que se trató satisfactoriamente con daptomicina. La daptomicina puede ser un tratamiento alternativo para las infecciones por Enterococcus resistente a la vancomicina (ERV) en los niños. Se necesitan más estudios para ampliar su uso.

Abstract Objective The potential role of procalcitonin (PCT) in the diagnosis of catheter-related bloodstream infection (CRBSIs) is still unclear and requires further research. The diagnostic value of serum PCT for the diagnosis of CRBSI in children is evaluated here. Method This study was conducted between October 2013 and November 2014, and included patients with suspected CRBSI from 1 month to 18 years of age who were febrile, with no focus of infection, and had a central venous catheter. Levels of PCT and other serum markers were measured, and their utility as CRBSI markers was assessed. Additionally, the clinical performance of a new, automated, rapid, and quantitative assay for the detection of PCT was tested. Results Among the 49 patients, 24 were diagnosed with CRBSI. The PCT-Kryptor and PCT-RTA values were significantly higher in proven CRBSI compared to those in unproven CRBSI (p = 0.03 and p = 0.03, respectively). There were no differences in white blood cell count and C-reactive protein (CRP) levels between proven CRBSI and unproven CRBSI. Among the 24 patients with CRBSI, CRP was significantly higher among those with Gram-negative bacterial infection than in those with Gram-positive bacterial infections. PCT-Kryptor was also significantly higher among patients with Gram-negative bacterial infection than in those with Gram-positive bacterial infections (p = 0.01 and p = 0.02, respectively). Conclusions The authors suggest that PCT could be a helpful rapid diagnostic marker in children with suspected CRBSIs.
Resumo Objetivo O possível papel da procalcitonina (PCT) no diagnóstico de infecções de corrente sanguínea relacionadas a cateter (ICSRCs) ainda não está claro e precisa ser mais pesquisado. O valor diagnóstico da PCT sérica para o diagnóstico de ICSRC em crianças é avaliado neste estudo. Método Este estudo foi feito entre outubro de 2013 e novembro de 2014 e incluiu pacientes com suspeita de ICSRC de um mês a 18 anos que estavam febris, não tinham foco de infecção e tinham cateter venoso central. Foram medidos os níveis de PCT e de outros marcadores séricos, cuja utilidade como marcadores de ICSRC foi avaliada. Adicionalmente, foi testado o desempenho clínico de um novo ensaio quantitativo automatizado e rápido para a detecção de PCT. Resultados Dentre 49 pacientes, 24 foram diagnosticados com ICSRC. Os valores de PCT-Kryptor e PCT-RTA foram significativamente maiores em ICSRCs comprovadas do que em ICSRCs não comprovadas (p = 0,03 e p = 0,03, respectivamente). Não houve diferença na contagem de glóbulos brancos e nos níveis de proteína C reativa (PCR) entre ICSRCs comprovadas e ICSRCs não comprovadas. Dentre os 24 pacientes com ICSRC, a PCR era significativamente maior entre aqueles com infecção bacteriana gram-negativa do que naqueles com infecção bacteriana gram-positiva. O PCT-Kryptor também foi significativamente maior entre pacientes com infecção por bactérias gram-negativas do que naqueles com infecção por bactérias gram-positivas (p = 0,01 e p = 0,02, respectivamente). Conclusões Sugerimos que a PCT pode ser um marcador de diagnóstico rápido útil em crianças com suspeita de ICSRCs.

La sarcoidosis, un trastorno multiorgánico de etiología desconocida que afecta varios órganos, es poco frecuente en los niños. Se desconocen la incidencia y la prevalencia reales de la sarcoidosis infantil. Al igual que en los adultos, muchos niños con sarcoidosis tal vez no presentan síntomas y la enfermedad cursa sin diagnosticarse. Es fundamental realizar una evaluación completa y sistemática del paciente para establecer el diagnóstico de sarcoidosis en los niños. Se describe el caso de una nina de 12 años con uveítis y hepatoesplenomegalia de dos años de evolución. Mediante una tomografía computarizada del tórax, se hallaron nódulos pulmonares periféricos dispersos y linfadenopatía hiliar bilateral. La aspiración de médula ósea y la biopsia de hígado no fueron diagnósticas. La biopsia de pulmón mostró granulomas de células epitelioides no necrosantes. A la paciente se le diagnosticó sarcoidosis en virtud del hallazgo de inflamación granulomatosa y de la exclusión de entidades confusoras.
Sarcoidosis, a multisystem disorder of unknown etiology that involves multiple organs, is rare in children. The true incidence and prevalence of childhood sarcoidosis is unknown. As in adults, many children with sarcoidosis may be asymptomatic; the disease may remain undiagnosed. A complete and systematic evaluation of the patient is essential for the sarcoidosis diagnosis in children. Here, we describe a case of 12-year-old female who presented with 2 years history of uveitis and hepatosplenomegaly. A chest computerized tomography revealed scattered peripheral pulmonary nodules and bilateral hiliar lymphadenopathy. Bone marrow aspiration and liver biopsy were not diagnostic. A lung biopsy showed non-necrotizing epithelioid cell granulomas. She was diagnosed with sarcoidosis according to demonstration of granulomatous inflammation and the exclusion of confusable entities
