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 ...

Two pregnancies at risk for X-linked recessive Duchenne's muscular dystrophy were studied at 18 and 20 weeks. Fetal blood was obtained by placental aspiration for measurement of plasma creatine phosphokinase activity. Activity in the first fetus was 96 IU per liter, as compared to a control range of 0 to 150 IU per liter in 16 pregnancies not at risk for the disorder. The pregnancy continued, a...

Serum and plasma myoglobin and creatine kinase-MB catalytic activity were analysed in 157 patients admitted within 2 hours of the onset of chest pain (58 were retrospectively recognized as acute myocardial infarction). Serum and plasma values were highly correlated for both myoglobin and creatine kinase-MB. Plasma myoglobin appeared to be more sensitive than creatine kinase-MB for the early dia...

Context: Oral squamous cell carcinomas develop from a premalignant lesion or condition, which are due to a variety of aetiological factors. Early detection of these are necessary to prevent them from developing into carcinomas which can increase the mortality and morbidity. There are a variety of possible aids like histopathology, Hstiochemistry and Enzyme assays in diagnosing these lesions. Hi...

Objective: A number of different hormone changes have been described during the acute myocardial infarction (AMI), including those of the non-thyroidal illness syndrome (NTIS). Design and methods: We assessed the alterations of serum thyroid hormones, cytokines and cortisol levels in 30 patients with a first episode of AMI 4, 24, 48 h and 10 days (240 h) after the onset of the chest pain and we...
