SUMMARYA 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.

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.

The present study sought to assess the rational use of antimicrobial agents in a Brazilian intensive care unit (ICU) and its association with antimicrobial resistance in elderly patients admitted to the unit. Results: Choice of empiric and sensitivity-guided therapy was inadequate in > 80% and 59% of cases respectively. Inadequate antimicrobial therapy, whether empiric or sensitivity-guided, was positively correlated with bacterial resistance (r = 0.316; p = 0.001). Sensitivity testing revealed a 46.5% resistance rate to eight out of the ten most commonly used antibiotics.
