Serum creatine phosphokinase in normal newborns.

Serum Levels of Creatine Phosphokinase.

Increasing interest in serum enzyme levels in various conditions has led to recognition of the value of the estimation of creatine phosphokinase activity in muscular disorders. Interpretation of the results obtained has been hampered by the lack of adequate information about the ;normal range'. Data for the normal levels of creatine phosphokinase in cord blood, children, and adults are presented.

Assessment of The Diagnostic Capability of Serum Creatine Phosphokinase and Its Isoenzyme in Ectopic Pregnancy

Creatine phosphokinase values and myalgia during isotretinoin therapy

Background: Systemic isotretinoin is a very effective medication for the treatment of acne, but it has some side effects. One of its side effects is musculoskeletal problems such as increased levels of creatine phosphokinase (CPK), myalgia, and serious muscle damage such as rhabdomyolysis. The aim of this study was to evaluate the incidence of myalgia and its relationship with the elevation of ...

Cerebrospinal fluid creatine kinase in acutely psychotic patients.

Significantly elevated serum creatine phosphokinase concentrations have been demonstrated in 70% of patients with acute psychosis. Elevations in spinal fluid creatine phosphokinase (CPK) activity have been reported in several neurological diseases, often in association with otherwise normal routine spinal fluid studies. Spinal fluid and serum were obtained simultaneously from 11 patients with a...

Phenothiazine-induced dystonia associated with an increase in serum creatine phosphokinase.

A transient but considerable rise in serum creatine phosphokinase (CPK) levels occurred in six boys aged between 8 and 11 years and suffering from phenothiazine-induced dystonia. In one boy (Case 4), after the CPK level had returned to normal after withdrawal of the drug, its reintroduction orally at lower dosage caused a slight increase in the level of CPK in the absence of any recurrence of t...
