Article: A comparison of F waves in peripheral nerve disorders.
[show abstract] [hide abstract]
ABSTRACT: F waves have become integral parts of nerve conduction studies in particular. F minimum (Fmin), the most commonly assessed latency, represents the largest and the fastest conducting fibers. The diagnostic yields of other F wave parameters are not obvious. In the present study, we aimed to determine the value of F wave parameters in commonly seen peripheral nerve disorders. We studied the F responses in 118 patients who had been diagnosed with different types of neuropathies, clinically and electrodiagnostically, and 68 individuals were used as controls: A total of 470 motor nerve conduction studies and related F-wave parameters were analyzed. F maximum (Fmax) was the most commonly seen abnormal parameter in the present study, although Fmin has until now been the most commonly studied parameter in clinics routinely. Abnormalities of F waves were more frequently seen in the patients compared to those in the control group and the differences were significant for carpal tunnel syndrome and upper extremity radiculopathies. This large database showed that F wave evaluations should include not only Fmin but also Fmax.Electromyography and clinical neurophysiology 01/2006; 45(7-8):417-23. -
Article: C-reactive protein is an indicator for fatal outcomes in first-time stroke patients.
[show abstract] [hide abstract]
ABSTRACT: The causal relation of high sensitivity C-reactive protein (hsCRP) to ischemic cerebrovascular disease remains unclear, though an inflammatory effect has been suggested in many studies. The aim of our study was to evaluate serum hsCRP levels in ischemic stroke patients and in a control group, and to correlate the values with other generally known risk factors. A total of 47 patients with ischemic stroke and 26 control subjects were recruited. The cases were well-matched to controls for age and sex. Peripheral blood samples from stroke patients were obtained between 12-24 hours after the stroke. Serum levels of hsCRP were determined by chemoluminescence assay. The mean serum levels of hsCRP were found to be significantly higher in patients (3.12 +/- 4.4 mg/dL) than controls (0.39 +/- 0.6 mg/dL, p=0.0001). The level of hsCRP was above the risk limit in 39 patients (83.0%) and 7 controls (26.9%). The hsCRP values were not related to the presence of other vascular risk factors, except for cholesterol level. The correlation analysis of hsCRP revealed a linear correlation with death within six months and the presence of hypertension. Our results suggest that elevated serum hsCRP levels may be an indicator of fatal outcome in first-time stroke patients.Medical science monitor: international medical journal of experimental and clinical research 12/2005; 11(11):CR540-4. · 1.70 Impact Factor
