Unexpected results found in larvae samples from two postmortem forensic cases

Forensic Toxicology - In forensics, entomological specimens can be used as additional/alternative matrices to detect xenobiotics when human specimens are limited in their application. Despite some...     

The financial burden of an influenza outbreak in a small rehabilitation centre

We report an influenza outbreak in a 75‐bed rehabilitation centre and present the detailed microeconomic impact that it had during the season 2016/2017. The direct medical, direct non‐medical and indirect costs were calculated. The outbreak included 18 patients with influenza and 8 contact patients, leading to 86 days with isolation precautions. During the outbreak month, 25 (15%) employees were absent from work for 89 days (mean 3.6 days, SD ± 1.8), and during the entire influenza season 33 for 175 (5.3 ± SD 4.6) days, respectively. The economic burden related to the outbreak was 114 373 CHF (106 890 €, 112 131 $).     

B‐cell modulation of dendritic‐cell function: Signals from the far side

An appropriate immune response against a specific pathogen requires finely orchestrated interactions between the various cell populations within the immune system. At the same time, immunological tolerance to self must be maintained. DCs play an essential role in achieving these dual requisites. They coordinate adaptive immunity by integrating signals directly emanating from both infectious agents and cells of the immune system. Many such signals, especially those from innate cells and T cells, have been extensively characterized. In contrast, little is known about how B cells modulate function of DCs. B cells produce a variety of cytokines, including IL‐10 and IL‐6, which are known to influence DC function. In addition, Igs constitute the major secretory products of terminally differentiated B cells (plasma cells). DCs express various types of receptors for binding Ig, such as Fc receptors and C‐type lectin receptors. In accordance, Igs can regulate DC function depending on the receptors engaged. Here, we review the emerging immunomodulatory role of cytokines and Ig secreted by B cells. We discuss the evidence for how these B‐cell‐derived factors may shape the adaptive immune response by directly acting on DCs.     

Neurocognitive outcome in patients with hypertyrosinemia type I after long-term treatment with NTBC

Objective  

The implementation of NTBC into treatment of hypertyrosinemia type I (HT I) greatly improved survival by prevention of acute liver failure and hepatocellular carcinoma. However, there are first reports of cognitive impairment in patients with elevated plasma tyrosine concentrations.
