Risk factors and mortality of candidemia in a children's public hospital in Sao Paulo, Brazil.

Candida bloodstream infections in children are of special concern in neonatal and pediatric intensive care and patients with comorbidities. This study aimed to estimate the incidence and risk factors associated with mortality in candidemia cases occurring in a public children's hospital in Ribeirao Preto, Brazil. It is a retrospective transversal study. Every patient under the age of 18 admitted to the study facility from January 1, 2013, to December 31, 2019, was considered potentially eligible to be included if they had candidemia. We collected clinical data from medical records. We included 113 blood cultures yielding positive results for Candida. The incidence rate was 2.12 per 1000 admissions. The most common Candida species was Candida parapsilosis. Septic shock during the candidemia episode was the only clinical outcome associated with a relative risk-adjusted (RRa) of 2.77 with an interval >1 (1.12-6.85). Our findings show that the incidence rate and mortality rates of candidemia are in line with those in other children's services in Brazil. We found a global mortality rate of 28.31% (32/113) from candidemia episodes. We highlight the predominance of non-albicans Candida species including C. parapsilosis. Septic shock was the most important factor showing a significant risk of mortality.

Polyarteritis nodosa with central nervous system involvement mimicking meningoencephalitis.

OBJECTIVE: To describe a patient who had polyarteritis nodosa with central nervous system involvement mimicking infectious meningoencephalitis. DESIGN: Case report. SETTING: Pediatric intensive care unit of a university hospital. PATIENT: A 9-yr-old boy with prolonged fever, headache, decreased level of consciousness, neck stiffness, and papilledema. RESULTS: Cerebrospinal fluid examination showed pleocytosis and a high protein level. After neurologic deterioration resulted from the initial treatment with antibiotic, the combination of clinical and laboratory findings with neuroradiologic features led to suspected systemic vasculitis. The patient was treated subsequently with corticosteroid, which resulted in great improvement. Biopsy of a skin lesion confirmed the diagnosis of polyarteritis nodosa. CONCLUSIONS: Critical care physicians must recognize neurologic manifestation patterns of systemic vasculitides because appropriate diagnosis and therapy result in significantly improved morbidity and mortality.
