The pathologies of oculopharyngeal muscular dystrophy (OPMD) and oculopharyngodistal myopathy (OPDM) are indistinguishable. We found that p62-positive intra-nuclear inclusions (INIs) in myonuclei (myo-INIs) were significantly more frequent in OPMD (11.4 {+/-} 4.1%, range 5.0- 17.5%) than in OPDM and other rimmed vacuolar myopathies (RVMs) (1-2% on average, range 0.0-3.5%, p<0.0001). In contrast, INIs in nonmuscle cells (nonmuscle-INIs) were present in OPDM, but absent in other RVMs, including OPMD. These results indicate that OPMD can be differentiated from OPDM and other RVMs by the frequent presence of myo-INIs ([&ge;]5%) and the absence of nonmuscle-INIs in muscle pathology.

"Similar papers" are the closest papers from that journal in the model's embedding space. They show what the match is built on, but the ranking comes mostly from a classifier over the whole training set, not from these examples alone.
