[Streptococcus pneumoniae endocarditis in a child: a case report].

Introduction: the incidence of invasive infections caused by pneumococcus (Streptococcus pneumoniae) has declined since generalized vaccination with pneumococcal conjugated vaccine, but it is still a prevalent pathogen in children. Amongst pneumococcal invasive infections, IE (infectious endocarditis) is rare, with an incidence between 1 and 7%.

Case Report: We describe the case of a previously healthy 4 year old boy, who had received one dose of 10-valent pneumococcal conjugate vaccine who presents with fever, a new heart murmur and heart failure.

Frailty prevalence and slow walking speed in persons age 65 and older: implications for primary care.

Background: Frailty in the elderly increases their vulnerability and leads to a greater risk of adverse events. According to various studies, the prevalence of the frailty syndrome in persons age 65 and over ranges between 3% and 37%, depending on age and sex. Walking speed in itself is considered a simple indicator of health status and of survival in older persons.

Retraction and triangulation with neodymium magnetic forceps for single-port laparoscopic cholecystectomy.

Introduction: There have been attempts to minimize the invasiveness of laparoscopic cholecystectomy by reducing the size and/or the number of the operating ports and instruments. These attempts create technical challenges related principally to retraction and triangulation necessary to expose the surgical field for a safe surgery. A new technique based on retraction and triangulation with magnetic instruments for single port laparoscopic surgery is presented.

Prevalence of HIV-1 non-B subtypes, syphilis, HTLV, and hepatitis B and C viruses among immigrant sex workers in Madrid, Spain.

Sexually transmitted disease (STD) remains a major public health challenge in developed countries, exacerbated by the advent of the HIV epidemic. The objectives of this study were to assess the prevalence of serological markers of syphilis, HIV-1/2, HTLV-I/II, HBV, and HCV infections among immigrant sex workers in Madrid, Spain and to characterize the HIV-1 variants in seropositive individuals. Sera from 762 immigrant commercial sex workers (75.

Replacement of protease inhibitors by nevirapine or efavirenz in simplification and rescue interventions: which works better?

The outcome of 162 patients replacing protease inhibitors (PIs) by nonnucleoside reverse transcriptase inhibitors (NNRTIs) was retrospectively assessed. After 48 weeks of follow-up, nevirapine (NVP) and efavirenz (EFV) performed similarly well in simplification interventions in patients with undetectable viremia, while EFV provided significantly better results in rescue interventions after PI failure. Previous suboptimal exposure to nucleoside analogs conditioned lower chances of virologic success using either NVP or EFV.
