OBJECTIVES: The aim of this study was to analyze the value of performing laboratory tests, taking cultures, and imaging, a diagnostic approach for febrile seizures (FSs) still routinely performed despite the American Academy of Pediatrics recommendations not to. Another aim of this study was to identify the most common sources of fever in patients with FSs and to determine whether the occurrence of FSs correlates with the seasons of the year. METHODS: This is a retrospective study that included all patients diagnosed with simple or complex FSs who were seen in the emergency room or inpatient unit from January 2004 to December 2009. RESULTS: Of the 219 patients included in the study, 135 (61.4%) cases had the etiology of the FS diagnosed. Upper respiratory tract infection, otitis media, urinary infection, and pneumonia were the most common diagnoses attributed to the fever. Leukocytosis was present in 48 (24%) of 219, and neutrophilia in 199 (91%) of 219 cases. Low bicarbonate levels were common among every age group. Only 1 blood culture was positive for Salmonella. The incidence of FS was higher during the winter (49.3% of the cases), and it closely paralleled the seasonal variation of viral infections. CONCLUSIONS: Even though laboratory tests, taking cultures, and imaging are performed in daily practice when approaching FSs, the association of FSs with serious infectious disease is rare and usually overestimated. The diagnostic approach should be individualized to each case and correlated with available data like that shown in this study. Parents should be educated with the knowledge that the occurrence of FSs tends to be higher in winter.

Community-acquired methicillin-resistant Staphylococcus aureus has become a well-established pathogen with alarming rates during the last decade. The current situation of this bacteria in pediatric infections is very limited and motivated us to conduct this study. This is a retrospective and analytical study including patients less than 18 years of age with the diagnosis of skin or soft tissue infections in 2008 and 2009 meeting the criteria of Community-acquired infection. A prevalence of 41.9% among skin and soft tissue infections was found. Inducible resistance to clindamycin was detected in 1.3% of the strains and the infection shows a seasonal predilection for summer (P=0.003); 57.8% of the cases required hospitalization with a mean stay of 3.3+/-2.5 days. The susceptibility to clindamycin and co-trimoxazole is 88 and 97% respectively. The resistance to erythromycin has reached 92%. The main diagnoses at presentation was gluteal abscess plus cellulitis (34.2%).The prevalence of CA-MRSA is trending up and seems to become a large burden for the health system in our community. Clindamycin is still an excellent option in the community setting since inducible clindamycin resistance is extremely low in this community. Co-trimoxazole should be kept as a reserved drug to avoid the rapid resurgence resistance in the community.
