  Another rare disorder linked to CPT II deficiency is manifest in infancy as hypoketotic hypoglycemia, hepatomegaly and hepatic failure, cardiomegaly and arrhythmias, lethargy, seizure, and coma. [emedicine.com]

  Hepatomegaly, macroglossia, cardiomegaly and early respiratory muscle involvement are common in infantile and childhood varieties. Infantile form is fatal before 2 years of age. [annalsofneurosciences.org]

  My main complaints are cramping and hyper-toned muscles, muscle spasms, exercise intolerance, pain due to these and also minor soft tissue injuries, some fasciculations and sleep disturbances. [doctorslounge.com]

  In young patients who play baseball or softball, the “home run” sign (Haller sign), inability to sprint around the bases due to exercise-induced muscle spasms, is a typical complaint in patients with glycogenoses, such as McArdle disease. [neupsykey.com]

Seven of 19 patients with elevated CK consented to neurologic workup. Two of the 7 had elevated resting lactate. [ncbi.nlm.nih.gov]

Because these symptoms may be nonspecific and lack any clear temporal or anatomic pattern, their workup may entail costly and uninformative tests. [the-rheumatologist.org]

However, a key diagnostic feature is the absence of a rise in serum venous lactate during the Forearm ischemic exercise test in Workup. Also, the cramp, when recorded by needle EMG, is silent (contracture). [emedicine.com]

Treatment varies greatly depending on the biochemical nature of the disease, and unfortunately no definitive treatments exist for metabolic myopathy. [ncbi.nlm.nih.gov]

When present, seizures may be intractable and associated with a poor prognosis. A 10-month-old child presented with focal status epilepticus in association with a viral infection and a normal brain MRI. [bcmj.org]

Not all muscle cramps, however, are related to metabolic muscle diseases and can be due to benign etiologies. When benign entities are ruled out and metabolic myopathy is suspected, the first diagnostic step is to perform an electromyogram. [bcm.edu]

Accordingly, metabolic myopathies can be etiologically classified into three broad categories: glycogen storage diseases (GSDs), fatty acid oxidation (FAO) disorders, and mitochondrial diseases. [neupsykey.com]

Discussion The etiology of this entity is still unknown, and no general agreement exists regarding its pathogenesis. 1, 4, 6, 7 In a review by Smack et al, 3 121 cases of TC were identified. [nature.com]
