[Schwannoma, a rare swelling of the tongue].

A 65-year-old woman presented with progressively increasing swelling on the right lateral side of her tongue. Further investigation confirmed it to be a schwannoma. Surgical excision of the tumour was performed, resulting in an uncomplicated postoperative recovery with complete preservation of the tongue function.

Induction of Cure in Early Arthritis (I CEA): study protocol for an investigator-initiated randomized single-blind clinical trial with open-label extension to compare three treatment strategies in patients with newly diagnosed undifferentiated arthritis.

Background: Undifferentiated arthritis (UA) is a term used to describe patients with inflammatory arthritis that has not differentiated into a specific rheumatic disease. UA may be a pre-stage of rheumatoid arthritis (RA) or another inflammatory disease or remain undifferentiated, but a substantial proportion of patients may also achieve spontaneous remission. As UA may be an early presentation of RA, rheumatologists often start methotrexate (or another csDMARD) as early as possible.

Alternative for HPC22 after repairs in the drinking water distribution system.

There is a risk of contamination by (pathogenic) microorganisms from the outside environment into the drinking water during maintenance or pipe breaches in the drinking water distribution system (DWDS) and, consequently, the drinking water distributed to consumers may result in possible detrimental effects on public health. Traditional time-consuming microbiological testing is, therefore, performed to confirm drinking water is not microbially contaminated. This is done by culturing methods of the faecal indicators Escherichia coli, intestinal enterococci and the technical parameters coliform bacteria and heterotrophic plate counts at 22 °C (HPC22).

Epstein-Barr virus nuclear antigen EBNA3A modulates IRF3-dependent IFNβ expression.

Epstein-Barr virus (EBV), the causative agent of infectious mononucleosis, persistently infects over 90% of the human adult population and is associated with several human cancers. To establish life-long infection, EBV tampers with the induction of type I interferon (IFN I)-dependent antiviral immunity in the host. How various EBV genes help orchestrate this crucial strategy is incompletely defined.

Regional variation in the interpretation of contact precautions for multi-drug-resistant Gram-negative bacteria: a cross-sectional survey.

Background: Contact precautions are recommended when caring for patients with carbapenemase-producing Enterobacterales (CPE), carbapenemase-producing Pseudomonas aeruginosa (CPPA), and extended-spectrum β-lactamase-producing Enterobacterales (ESBL-E).

Aim: Our aim was to determine the interpretation of contact precautions and associated infection prevention and control (IPC) measures in the non-ICU hospital setting for patients with CPE, CPPA or ESBL-E in 11 hospitals in the Southwest of the Netherlands.

Methods: A cross-sectional survey was developed to collect information on all implemented IPC measures, including use of personal protective equipment, IPC measures for visitors, cleaning and disinfection, precautions during outpatient care and follow-up strategies.
