Borderline oxacillin-resistant Staphylococcus aureus carriage among healthcare workers at neonatal intensive care unit and paediatric ward.

Background: During a meticillin-resistant Staphylococcus aureus contact tracing and screening investigation, two borderline oxacillin-resistant Staphylococcus aureus (BORSA)-positive screening cultures were encountered among neonatal intensive care unit (NICU) healthcare workers (HCWs). This finding led to further investigations.

Aim: To assess the likelihood of an outbreak with direct transmission among HCWs.

Abnormalities suggestive of latent tuberculosis infection on chest radiography; how specific are they?

Background: Several radiological features have been reported in association with latent tuberculosis infection (LTBI) but it has not been studied which are specific. The aim of this study was to evaluate allegedly characteristic abnormalities on chest radiography (CXR) in patients with LTBI compared to uninfected controls.

Methods: From 236 patients tested with QuantiFERON-TB Gold In-Tube (QFT), the CXR was re-evaluated in a blinded fashion for fibrotic scarring, (non-)calcified nodules and pleural thickening.

Establishment and first experiences of the National Serum Depot in the Netherlands.

Since 2008, a National Serum Depot is operational in the Netherlands, guaranteeing antivenom supply, 24 h per day, during medical emergencies. In this article the organisation structure, choice of antivenoms, problems encountered during the establishment, and the results from establishment in 2008 till December 2011 are discussed. The Serum Depot is organised by the National Institute for Public Health and the Environment in cooperation with the Dutch National Poisons Information Center.

Immunologic effects of background prenatal and postnatal exposure to dioxins and polychlorinated biphenyls in Dutch infants.

Immunologic effects of pre- and postnatal polychlorinated biphenyl (PCB)/dioxin exposure in Dutch infants from birth to 18 mo of age are explored. The total study group consisted of 207 healthy mother-infant pairs, of which 105 infants were breast-fed and 102 children were bottle-fed. Prenatal PCB exposure was estimated by the PCB sum (PCB congeners 118, 138, 153, and 180) in maternal blood and the total toxic equivalent (TEQ) level in human milk (17 dioxin and 8 dioxin-like PCB congeners).
