RESUMEN
According to the 2020 CDC criteria, multisystem inflammatory syndrome in children (MIS-C) due to Coronavirus disease-19 (COVID-19) is diagnosed when all of the following criteria are met: fever for+≥+24 hours, laboratory evidence of inflammation, multisystem (+≥+2) organ involvement, evidence of SARS-CoV-2 infection or exposure, and no alternative plausible diagnoses (CDC, 2020). Alternative diagnosis need to be excluded before coming upon an MIS-C diagnosis since there are plenty of infectious diseases that may mimic MIS-C (Dworsky et al., Pediatr Infect Dis J 2021; 40; e159-e161; Yalçinkaya et al., Pediatr Infect Dis J 2021; 40; e524-e525; Kaneta et al., Pediatr Infect Dis J 2023; 42; 590-593; Stanzelova et al., Pediatr Infect Dis J 2023; 42; e201-e203; Kolsi et al., Arch Pediatr 2023; 30; 521-523). Herein, we present a 6-year-old girl who was preliminarily diagnosed with MIS-C and received intravenous immunoglobulin (IVIG) treatment before referral to our center. She was diagnosed with acute pneumococcal meningitis due to serotype 19 F and ultimately suffered from sensorineural hearing loss (SNHL) as a sequela. We present this case to remind physicians that MIS-C should not be diagnosed unless other infectious causes are excluded.
RESUMEN
INTRODUCTION: Human brucellosis is one of the most common zoonotic infections in the world. The definitive diagnosis of brucellosis is based on cultured Brucella organisms from blood or other tissue samples. We aimed to compare bacteremic and nonbacteremic brucellosis patients with demographical, epidemiological, clinical and laboratory features and determine the predictive factors affecting blood culture positivity. MATERIALS AND METHODS: Children aged 1 month to 18 years who were followed up with the diagnosis of brucellosis between January 2005 and March 2021 were included in this retrospective study. According to the isolation of Brucella melitensis in blood culture, the patients were divided into two groups as bacteremic and nonbacteremic and compared in terms of demographic, clinical and laboratory characteristics. RESULTS: One hundred eighty-nine (116 male, 61.4%) patients diagnosed with brucellosis were included in the study. There were 76 (40.2%) bacteremic and 113 (59.8%) nonbacteremic patients. Bacteremic patients were younger than nonbacteremic patients. Fever, arthralgia, hepatomegaly and splenomegaly were significantly higher in the culture positive group. High levels of C-reactive protein (CRP), aspartate aminotransferase (AST) and alanine aminotransferase (ALT) were found to be significant in the bacteremic group. CONCLUSION: In our study, history of fever and arthralgia, hepatomegaly and splenomegaly in physical examination and high CRP, ALT and AST levels in the biochemical analysis were important factors determining blood culture positivity.

The pathophysiology of multisystem inflammatory syndrome (MIS) in children (MIS-C) is unknown. It occurs several weeks after COVID-19 infection or exposure; however, MIS is rarely reported after COVID-19 vaccination, and cases are mostly in adults. Herein, we present a 12-year-old male who had no prior COVID-19 infection or exposure and developed MIS-C after his first dose of COVID-19 mRNA vaccine.
