introduction: several mechanisms were introduced as causes of serum creatinine phosphokinase (cpk) raise in intoxicated patients. this study aimed to assess the relationship between serum cpk level in the first 24 hours and baseline characteristics as well as outcomes of these patients. methods: this one year retrospective cross-sectional study was conducted on all intoxicated patients, who wer...

OBJECTIVES: (1) To investigate the significance of assessment of serum levels of cardiac troponin I (cTnI) and interleukin-8 (IL-8) beside other biomarkers of myocardial injury in scorpion envenomed children. (2) To find the correlation between these biochemical indices with clinical status, prognosis and outcome of these cases. METHODS: Forty-one children in Upper Egypt were admitted to Pediat...

To study the frequency and examine the role of rhabdomyolysis in the acute renal failure in tetanus 18 patients with the diagnosis of generalized tetanus consecutively admitted to the infectious disease hospital were evaluated. Of these 14 were male and 4 female with mean age of 31.8 +/- 2.0 years. Except for mild proteinuria recorded in 9 patients, the urinalysis were unremarkable. Serum creat...

The specificity of serum CPK-MB for acute myocardial infarction was examined by retrospective analysis of 401 consecutive patients admitted to a Coronary Care Unit over a three and one-half year period with suspected infarction in whom the isoenzyme was subsequently detected. Four patients (1% ) who died during the hospital admission had no autopsy evidence of acute myocardial infarction. All f...

Process capability index Cpk has been widely used in the manufacturing industry as a process performance measure. In this paper, we investigate the natural estimator of the index Cpk, and show that under the assumption of normality its distribution can be expressed as a mixture of the chi-square and the normal distributions. We also implement the theory of hypothesis testing using the natural e...

A 19-year-old white man with familial hypokalemic periodic paralysis developed evidence of cardiac dysfunction during a episode of flaccid paralysis. This consisted of elevated total creatine phosphokinase (CPK), an increased myocardial fraction of CPK (myocardial band), alteration in the lactic dehydrogenase isoenzyme pattern, severe bradycardia, and evidence of left ventricular dysfunction. T...

− μ + σ − = μ = process mean T = process target This edition of Tech Topics takes a close look at the quality measure Cpk and related indices. Through its general acceptance, Cpk has established its value. It is important, however, to keep its limitations in mind. Jim Marshall, the author, has held numerous quality, process and development engineering positions during his career at KEMET. Dr. J...
