Incidencia y factores asociados a sepsis en victimas quemadas internadas en un hospital brasileño / Incidence and factors associated with sepsis in burned victims admitted to a Brazilian hospital

OBJETIVO: Conocer la incidencia de sepsis y los factores asociados en las víctimas de quemaduras. MÉTODO: Estudio retrospectivo, en que el diagnóstico de sepsis fue confirmado por los criterios de definición de sepsis de la Asociación Americana de Quemaduras. Se investigó la asociación entre sepsis y las características del paciente, las quemaduras y el tiempo de hospitalización. RESULTADOS: La incidencia de sepsis fue 14,5% (n=27) de los pacientes y 77,7% (n=21) evolucionaron para alta hospitalaria. La incidencia de sepsis fue asociada con el porcentaje de superficie corporal quemada mayor que 10% (p<0,001) y una estadía hospitalaria mayor que 10 días (p<0,001). La mortalidad fue mayor en pacientes con sepsis (p=0,002). Hubo un cambio en la frecuencia de prescripción de antimicrobianos con el diagnóstico de sepsis, algunos foram prescritos solamente antes (ciprofloxacina, cefalotina, ceftriaxona, amoxicilina y gentamicina) y otros solamente durante el episodio de sepsis (tigeciclina, piperacilina y tazobactam, fluconazol y linezolida). CONCLUSIÓN: La incidencia de sepsis fue baja y está asociada con muerte. Se identifico que, el porcentaje de superficie corporal quemada y la duración de la estadía hospitalaria, están significativamente asociados con la incidencia de sepsis. La sepsis cambió el perfil del uso de antimicrobianos.

OBJECTIVE: To assess the incidence of sepsis and factors associated with casualties of burns. METHODS: This is a retrospective study, in which the diagnosis of sepsis was confirmed by the criteria for definition of sepsis of the American Association of Burns. If we investigate the association between sepsis and patient characteristics, burns and hospitalization time. RESULTS: The incidence of sepsis was 14.5% (n=27) of patients and 77.7% (n=21) evolved to hospital discharge. The incidence of sepsis was associated with a body surface area percentage greater than 10% (p<0.001) and a greater state than 10 days (p <0.001). Mortality was higher in patients with sepsis (p=0.002). There was the change of antimicrobial profile. Same medicines was used only before the diagnosis (ciprofloxacin, cephalothin, ceftriaxone, amoxicillin and gentamicin) and other only after the sepsis diagnosis (tigecycline, piperacillin and tazobactam, fluconazol and linezolida). CONCLUSION: The incidence of sepsis is low and is associated with the disease. It has been found that the percentage of body surface burned and the length of hospital stay is significantly associated with the incidence of sepsis. The sepsis causes the change of antimicrobial use profile.

CHYLOTHORAX IN PARACOCCIDIOIDOMYCOSIS.

A previously healthy, 52-year-old woman presented with a nine months history of low fever and weight loss (> 30 kg). Physical examination disclosed generalized lymphadenopathy, skin lesions, abdominal distension, mild tachypnea and a left breast mass. Laboratory tests showed anemia; (prerenal) kidney injury, low serum albumin level; and negative serology for HIV and viral hepatitis. Computed tomography (neck/chest/abdomen) showed generalized lymph node enlargement, splenomegaly, pleural effusion and ascites. We performed thoracocentesis and paracentesis, and the findings were consistent with chylothorax and chylous ascites (with no neoplastic cells). Biopsies of the breast mass, skin and lymph nodes were performed and all of them showed large round yeast cells with multiple narrow-based budding daughter cells, characteristic of Paracoccidioides brasiliensis. Consequently, paracoccidioidomycosis was diagnosed, and liposomal amphotericin B was prescribed, as well as a high protein and low fat diet (supplemented with medium chain triglycerides). Even so, her clinical status worsened, requiring renal replacement therapy. She evolved with pneumonia, septic shock and respiratory failure and subsequently died. To our knowledge, this is the first description of a case with chylothorax and breast mass due to paracoccidioidomycosis. Additionally, we discuss: 1- the importance of the inclusion of this mycosis in the differential diagnosis of chylothorax and breast mass (breast cancer), especially in endemic areas; and 2- the possible mechanism involved in the development of chylous effusions.

Surgical Site Infection Rates in Four Cities in Brazil: Findings of the International Nosocomial Infection Control Consortium.

BACKGROUND: There are no data on surgical site infection (SSI) rates stratified by surgical procedures (SPs) in Brazil, and our objective was to report such rates. METHODS: From January 2005 to December 2010 we conducted a surveillance study on SSIs in four hospital members of the International Nosocomial Infection Control Consortium (INICC) in four Brazilian cities. We applied the U.S. Centers for Disease Control and Prevention's National Healthcare Safety Network's (CDC-NHSN's) surveillance methods. Surgical procedures were classified into following types following International Classification of Diseases (ICD-9) criteria. RESULTS: We recorded 349 SSIs, associated to 61,863 SPs (0.6%; [CI], 0.5-0.6). SSI rates per type of SP were compared with INICC and CDC-NHSN reports, respectively: 2.9% for cardiac surgery (vs. 5.6%, p = 0.001 vs. 1.3%, p = 0.001); 0.4% for cesarean section (vs. 0.7%, p = 0.001 vs. 1.8%, p = 0.001); 5.4% for craniotomy (vs. 4.4% p = 0.447 vs. 2.6% p = 0.005) and 1.1% for vaginal hysterectomy (vs. 2.0% p = 0.102 vs. 0.9% p = 0.499.) CONCLUSIONS: Our SSI rates were greater in two of the four analyzed types of SPs compared with CDC-NHSN, but similar to most INICC rates. These findings on the epidemiology of SSI in Brazil will enable us to introduce targeted interventions for infection control.
