Bactibilia and Antibiotic Resistance in Elective Cholecysctectomy: An Updated Ecologic Survey.

Background: The role of bactibilia as a risk factor for an unfavorable outcome during biliary disease or surgical procedures remains obscure. Our aim was to identify possible risk factors for bactibilia and their possible relations to complications after elective cholecystectomy. As secondary aims, composition and antibiotic resistance patterns were studied.

Post traumatic splenic function depending on severity of injury and management.

Because splenectomy has been linked to overwhelming infection years ago, management of splenic traumatisms has become progressively conservative. To assess the immunological function of the spleen in patients with splenic traumatism of different intensity, 43 patients with splenic injury (grades I through V) undergoing either nonoperative management, splenectomy, splenectomy with autotransplantation, or splenic embolization were analyzed for lymphocyte subpopulations and antibody responses to Streptococcus pneumoniae and Haemophilus influenzae vaccinations. Patients treated with splenectomy exhibited a significant decrease in CD4+ T lymphocytes and in Immunoglobulin (Ig) M(high)IgD(low) B cells (related to T-cell independent responses).
