Sera and synovial fluids from children with rheumatoid arthritis (RA) were examined for antibody to some viral and mycoplasmal antigens. Blood sera from the patients were found to have a selective excess of antibody to rubella virus as compared with the age norm. Antibody of this specificity was found in synovial fluids in titers significantly higher than those in the blood. Titers of other antibodies in the synovial fluids were, as a rule, slightly lower than in sera. In the time course of intercurrent respiratory diseases, despite the lack of rubella introduction into the wards, children with RA showed variations in the levels of antibody to rubella virus much more frequently than to other infectious agents. The foregoing data are discussed from the point of view of the etiological association of juvenile RA with rubella virus persistence. The antigen of the latter was found in snyovial membrane cells of 4 children by means of immunofluorescence procedure.

Rubella Virus, Cytomegalovirus (CMV), Herpes Simplex Virus-2 (HSV-2), Hepatitis B (HBV) and Hepatitis C virus (HCV) can cause serious fetal disease. The seropositivity rates of these agents vary among countries and geographic regions. This study aimed to analyze the prevalence rates and diagnostic methods used in studies investigating the seroprevalence of viral pathogens in the TORCH group among pregnant women in Turkey between 2005 and 2024.

Background and objective Viral infections caused by cytomegalovirus, lymphocytic choriomeningitis virus, varicella-zoster virus, herpes simplex type 1 and type 2, rubella, measles, rubeola, HIV, West Nile virus, Lassa virus, and mumps are known to be associated with hearing loss. There have been reports of inner ear involvement in coronavirus disease 2019 (COVID-19) patients but the extent and variations in cochlear involvement of symptomatic and asymptomatic patients has not been adequately described. This study aimed to evaluate the hearing status among symptomatic and asymptomatic COVID-19 patients to address the prospects for routine screening for hearing loss in COVID-19 patients.

The Société de Pathologie Infectieuse de Langue Française released in 2024 a new national recommendation for clinical practice on the prevention and management of varicella zoster virus (VZV) infection during pregnancy and the perinatal period. The previous recommendation was issued in 1998, at a time of anti-VZV immunoglobulins shortage; it has hence become obsolete. This recommendation is a formalized expert consensus focusing on infectious diseases management; it is drawn up by a multidisciplinary working group (infectiologists, obstetricians, pediatricians, microbiologists, midwives, hygienists).

Description: The aim of this American Gastroenterological Association (AGA) Clinical Practice Update (CPU) is to provide best practice advice (BPA) statements for gastroenterologists and other health care providers who provide care to patients with inflammatory bowel disease (IBD). The focus is on IBD-specific screenings (excluding colorectal cancer screening, which is discussed separately) and vaccinations. We provide guidance to ensure that patients are up to date with the disease-specific cancer screenings, vaccinations, as well as advice for mental health and general wellbeing.
