*Septic arthritis of the hip in an infant can lack fever, but presents with pseudo paralysis (due to pain), elevated WBCs, elevated CRP, and effusion. *Legg-Calvé-Perthes disease (idiopathic avascular necrosis of the hip) occurs in children aged 3-8, is insidious in onset, and does not have elevated inflammatory markers.

*Myotonic dystrophy is autosomal dominant, caused by CTG repeats with genetic anticipation. Classic form presents in adulthood with muscle weakness and myotonia (impaired muscular relaxation). Infantile presentation includes respiratory failure, hypotonia, inverted V upper lip, cataracts, poor feeding, and clubbed foot. Diagnosis is via genetic testing.
