Sexually transmitted diseases of the anus and rectum: Causal agents, coinfections, HIV infection and high-risk sexual behaviour.

Introduction And Objective: Sexually transmitted infections of the rectum and anus (STI-RA) mainly affect men who have sex with men (MSM). The incidence of STI-RA among them has increased in recent years.

Material And Methods: Retrospective study in patients with diagnoses of STI-RA in an STI unit during the years 2014 and 2015.

Risk factors for antimicrobial-resistant Neisseria gonorrhoeae and characteristics of patients infected with gonorrhea.

Background: There are very few data available regarding risk factors associated with antibiotic resistant-Neisseria gonorrhoeae.

Methods: A study was conducted on 110 samples from 101 patients with gonococcal infection, in order to describe their characteristics and compare them with the antimicrobial susceptibility profile of their samples.

Results: An association was observed between resistant infections and heterosexual men, older age, concurrent sexually transmitted infection, and unsafe sexual behaviors.

[Streptococcus agalactiae late-onset neonatal infections in Barcelona (1996-2010)].

Objetive: To study the characteristics and evolution of group B Streptococcus (GBS) late-onset diseases, over a period of 15years in 8hospitals the Barcelona area and analyze the possible impact of prophylactic measures for the prevention of early-onset neonatal infections.

Methods: Retrospective review of all patients diagnosed with late-onset neonatal disease due to GBS from 1996 to 2010.

Results: A total of 143 patients were diagnosed.

[Toxoplasmosis and pregnancy. Multicenter study of 16,362 pregnant women in Barcelona].

Background And Objective: The aim of this study was to know: 1) the prevalence of antibodies against toxoplasma in pregnant women, 2) the incidence of primary infection during pregnancy and 3) the prevalence of congenital toxoplasmosis.

Subjects And Method: Seroprevalence was prospectively analyzed in 16,362 pregnant women visited in 8 hospitals and 2 day care centers in Barcelona during 1999. Each participant laboratory included their own assays to detect toxoplasma-specific immunoglobulins IgM, IgA, IgG and IgG avidity antibodies.

[Comparative study of three culture media for detecting group B Streptococcus colonization in pregnant women].

Objective: To compare the efficacy of three culture media to detect vaginal and rectal colonization by group B streptococci (GBS) in pregnant women.

Methods: We processed 1334 samples from 861 pregnant women: in 388 patients only vaginal swab was cultured (Group A) and in 473 vaginal and rectal swabs were cultured (Group B). Samples were inoculated on blood agar with colistin-nalidixic acid (BA-CNA), on plates with Granada medium, and on Todd-Hewitt broth (THB) with amikacin followed by subculture in BA-CNA.
