Polymyositis and Dermatomyositis: (Second of Two Parts)
Abstract
Laboratory FeaturesElevation of sarcoplasmic enzymes in serum (creatine phosphokinase, aldolase, transaminases and lactic dehydrogenase) is valuable both for diagnosis and for following the clinical activity and response to treatment. Although some state that the transaminases are the most reliable,31,33,35 most authorities favor the creatine phosphokinase.2These serum enzymes are not infallible guidelines, for occasionally they remain entirely within the normal range despite active myositis1,51; likewise, when muscle atrophy is extensive in long standing disease, the enzymes may be normal despite active myositis. Motor-neuron diseases, Duchenne muscular dystrophy and other dystrophies, metabolic disorders, endocrinopathies, toxins . . .

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
