[Staphylococcus aureus bacteremia at a general hospital]. / Bacteriemias por Staphylococcus aureus en un hospital general.

70 cases of bacteremia caused by Staphylococcus Aureus were studied. 49 (70%) males, and 21 (30%) females; 45 (64.5%) cases being nosocomial and 25 (35.4%) community acquired. The complications were significantly associated to the community acquired bacteremia (p less than 0.001), endocarditis and cutaneous abscesses being the most frequent (4). The group of cases with rapidly lethal prognosis was significantly associated to an increase of mortality (p less than 0.001), while lethal and non-lethal groups showed a decrease in mortality (p less than 0.001). We did not find a statistically significant association between nosocomial and community acquired bacteremias nor between antibiotic therapy and the mortality rate, chi 2 = 1.747.303 (N.S.), chi 2 = 1.323.806 (N.S.).

[Sepsis at an internal medicine department]. / Sepsis en un departamento de medicina interna.

185 cases of bacteremia admitted at the internal medicine department of "C.S. Virgen de la Arrixaga" in Murcia from 1977 to 1986, were studied retrospectively. The common infection was significantly associated to Staphylococcus aureus, Streptococcus pneumoniae, Streptococcus A group and Neisseria meningitidis and the nosocomial infection was associated to Klebsiella Pneumoniae, Serratia Marcescens y Pseudomonas aeruginosa, Staphylococcus epidermidis and Enterobacter. We did not find significant differences between the common and nosocomial infection caused by E. Coli and Proteus mirabilis. These factors were associated to an increase of mortality: age greater than 40 years, nosocomial infection, Pseudomonas aeruginosa, other associated rapidly lethal diseases, acute clinical state at the beginning of bacteremia, shock and non-correct antibiotic therapy.
