Dosing for IgG and especially IgG2 anti-TIF1γ in adult dermatomyositis would refine cancer risk assessment
Anti-transcription intermediary factor 1 γ (TIF1γ) autoantibodies are associated, in adults with dermatomyositis, with an excess risk of cancer. A French study involving clinicians from the Institute of Myology had shown in 2019 that anti-TIF1γ of IgG2 subtype could be a biomarker of this tumor risk. A result confirmed by a retrospective international study conducted … [Read more]
The surgical treatment of myopathic ptosis remains complex

Neonatal screening for Pompe disease in Italy shows higher than expected incidence
The largest European study of newborn screening for Pompe disease was conducted in north-eastern Italy over a seven-year period and found: an incidence of 1 in 18,795 (i.e. 39 newborns with Pompe disease out of 206,741 tested). As in other countries (Taiwan, Japan, United States, etc.), newborn screening has revealed an increasing incidence of the … [Read more]
