Anaphylaxis Refractory to intra‐muscular adrenaline
Anaphylaxis Refractory to intra‐muscular adrenaline during in‐hospital food challenges: a case series and proposed management: AbstractBackgroundAnaphylaxis is a severe, systemic hypersensitivity reaction, that can be potentially life threatening. Anaphylaxis during oral food challenge is not uncommon and can usually be effectively managed with intramuscular adrenaline as first line treatment. Although very rare, fatal anaphylaxis during in‐hospital food challenge has been reported.ObjectiveWe describe...

A simple automated approach to measure mouse whole gut transit
A simple automated approach to measure mouse whole gut transit: AbstractBackgroundGastrointestinal (GI) motility is a complex physiological process that is critical for normal GI function. Disruption of GI motility frequently occurs in GI diseases or as side effects of therapeutics. Whole gut transit measurements, like carmine red leading‐edge transit, in mice form the cornerstone of in vivo preclinical GI motility studies.MethodWe have developed an easily achievable, labor‐saving method to measure...

Global 3D parameter of the spine: application of Călugăreanu–White–Fuller theorem in classification of pediatric spinal deformity
Global 3D parameter of the spine: application of Călugăreanu–White–Fuller theorem in classification of pediatric spinal deformity: AbstractSeveral classification systems of the spinal curves in adolescent idiopathic scoliosis (AIS) have been developed to guide surgical decision-making. The current classification systems are based on the spinal deformity patterns or deformity magnitudes in one or two anatomical planes. Considering the 3D nature of the spinal deformity in AIS, these classifications...

 SARS-CoV-2 samples may escape detection because of a single point mutation in the N geneWe found that a single nucleotide polymorphism (SNP) in the nucleoprotein gene of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) from a patient interfered with detection in a widely used commercial assay. Some 0.2% of the isolates in the EpiCoV database contain this SNP. Although SARS-CoV-2 was still detected by the other probe in the assay, this underlines the necessity of targeting two independent...
