“…1,3,8 According to other studies, persistent bacteremia after the fifth day and sepsis on admission are associated with an increased risk for morbidity and mortality. 9 In the clinical case described here, the early search for metastatic infections led to a timely treatment, considering the persistence of positive blood cultures and the patient's age as factors associated with a greater morbidity. 1 Regarding the search for deep sites of infection or metastatic infections, although ancillary tests -such as an echocardiogram and fundus oculi-were requested, it is important to note the higher frequency of pulmonary involvement in pediatric patients; therefore, it was relevant to search for this source of infection with an X-ray and computed tomography of the chest.…”

Bacteremia due to Staphylococcus aureus is defined as the isolation of this microorganism in at least one blood culture. A metastatic infection is caused by the hematogenous dissemination and subsequent location of the microorganism in a site other than the one where the infection started. The prevalence of these secondary sources of infection is low in the pediatric population, which is a diagnostic challenge.Here we describe the case of a pediatric patient with facial cellulitis due to Staphylococcus aureus, with metastatic infection and torpid course.

“…1,3,8 Según otros estudios, la persistencia de bacteriemia después del quinto día y la sepsis al ingreso se asocian con mayor riesgo de morbimortalidad. 9 En el caso clínico presentado, la búsqueda precoz de metástasis infecciosas arribó a un tratamiento oportuno, considerando la persistencia de los hemocultivos positivos y la edad del paciente como factores asociados a mayor morbilidad. 1 En cuanto a la búsqueda de focos profundos o metástasis infecciosas, si bien se solicitaron exámenes complementarios tales como ecocardiograma y fondo de ojo, es importante subrayar la frecuencia de compromiso pulmonar en pacientes pediátricos, por lo cual, fue pertinente la búsqueda de dicho foco a través de radiografía y tomografía de tórax.…”

La bacteriemia por Staphylococcus aureus se define como el aislamiento de dicho germen en al menos un cultivo de sangre. Las metástasis infecciosas se originan por diseminación hematógena y su posterior localización en un sitio distinto al órgano en donde se originó el proceso infeccioso. La prevalencia en la presentación de estos focos infecciosos secundarios es baja en la edad pediátrica, por lo que representa un desafío diagnóstico.Se presenta el caso de un paciente pediátrico con una celulitis facial por Staphylococcus aureus, con metástasis infecciosas y evolución tórpida.

“…In general, the most isolated microorganisms from patients with pneumonia are: Staphylococcus aureus, Pseudomonas aeruginosa, Acinetobacter baumannii and Klebsiella pneumoniae [4,5]. Among the factors that lead to infection, hospitalization for long periods, chronic disease, immunodeficiency, contact with contaminated hospital materials and exposure to antibiotics for a long period are the most common [6]. The risk group is formed by children, elderly ( (ITU) [7].…”

Nosocomial infections have been common in health services in Brazil. Among them, pneumonia is very highlighted due to the comorbidity that usually affects intensive treatment unit (ITU) patients, and due to the need for endotracheal intubation. The aim of this study was to determine the resistance profile of bacteria isolated from ITU patients with pneumonia in a public hospital in Sã o Luis, an important city in the Brazilian pre-Amazon region. Bacteria strains were obtained from tracheal aspiration and collected for diagnosis as well for phenotypic characterization. Standards culture media, such as blood and MacConkey agar, were used to isolate clinical strains. Automatized Vitek 2 method was used to identify strains and disc diffusion method (Kirby-Bauer) was performed to determine the antimicrobial susceptibility profile. During study, eighty-eight patients were diagnosed with pneumonia, caused by more than 20 different bacteria. Among them, P. aeruginosa (28%), Acinetobacter baumannii (20%), Coagulase-negative Staphylococci (19%), Staphylococcus aureus (8%) and Klebsiella pneumoniae (7%) were the most prevalent microorganisms. Regarding to the resistance, antimicrobial susceptibility test showed that majority of Gram-negative bacteria presented resistance to ampicillin. In Gram-positive bacteria there was a high resistance to ampicillin, penicillin, ciprofloxacin, clindamycin and erythromycin. This study showed a high prevalence of bacteria resistance in ITU patients in a public hospital. Although P. aeruginosa was the most frequent pathogen, it was possible to find other pathogens that were not recurrent, such as Enterobacter spp., Proteus mirabilis and Providencia stuartii. Regarding antimicrobials, the results showed a high resistance to several antimicrobials.
