Background: Candidemia is a nosocomial infection of increasing importance, associated with high morbidity and mortality. The aim of this study is to describe the species distribution, risk factors, management and outcomes of patients with candidemia.

Panton-Valentine leukocidin-producing Staphylococcus aureus (PVL-SA) is associated with relapsing multifocal skin and soft tissue infections (SSTI), necrotizing pneumonia (NP) and severe musculoskeletal infections. Epidemiology is underknown and underdiagnosis is likely. Recent travel abroad, case clustering and relapsing disease are often reported. We reviewed all cases of PVL-SA infection diagnosed at our center, and found 21 cases over a 43-month period. Most patients were adult males, had relevant travel history, reported recurrent disease and presented with SSTI. Etiologic diagnosis took up to five years; meanwhile, 42% of patients had antibiotic treatments. Draining procedures were required in 43% of patients and intensive care support in 19%. All patients recovered. Methicillin-resistance prevalence was 24%. Only 2/13 decolonized patients had posterior relapsing SSTI, both with likely infected contacts. PVL-SA infection’s severity and impact are clear, even in small case series as ours. Physician awareness and active PVL-gene search are crucial for an adequate management.

The spectrum of Neisseria meningitidis-associated clinical entities involves mild forms of disease, without neurological involvement or sepsis, and asymptomatic carrier states. Rarely, N. meningitidis bacteremia can be associated with a prolonged fever with or without arthritis, which we designate as chronic meningococcemia. Chronic meningococcemia is an uncommon entity, usually associated to serogroup B N. meningitidis. Diagnosis is frequently delayed as blood cultures collected outside febrile periods can be negative. We present a case of chronic meningococcemia in a 22-year-old woman with no relevant clinical background, presenting with fever, arthralgia and exanthem. Due to the potential for progression to more severe disease and the risk of N. meningitidis transmission and development of secondary cases, a high degree of clinical suspicion is required to ensure prompt recognition and adequate treatment. Our patient had a favorable outcome probably due to early recognition and adequate treatment, which is critical for the resolution of the disease without complications.
