RESUMEN
Carpal tunnel syndrome (CTS), majority of cases are considered to be idiopathic, is the most commonly encountered peripheral neuropathy causing disability. We asserted that thick and big hands may more prone to idiopathic CTS (ICTS) than others. The study included 165 subjects admitted to our electrophysiology lab with pre-diagnosis of CTS between May 2014 and April 2015. Eighty-five of the subjects were diagnosed as ICTS. The parameters analyzed were: age, gender, occupation, BMI, hand dominance, grade of ICTS, wrist circumference, proximal/distal width of palm, hand/palm length, hand volume and palm length/proximal palm width. Female gender was significantly higher in both groups. The mean age of study group was 44.02 ± 9.11 years, and control group was 41.25 ± 9.94 years. BMI, wrist circumference and hand volume were significantly higher in the study group (p < 0.05). However, palm length/prox.palm width ratio was higher in the control group (p = 0.00). There were also significant differences among CTS groups in terms of age (p = 0.001). Mean age was higher in severe CTS group. Female gender, older age and high BMI are risk factors for ICTS. Higher hand volume, wrist circumference and lower palm length/prox. palm width ratio can also be anthropometric risk factors. Large hand volumes, big and coarse hands are more prone to ICTS.

OBJECTIVE: This case is a patient with tongue myokymia following radiation therapy 12 years earlier, documented using video and EMG. CASE REPORT: A 68-year-old woman with a history of nasopharyngeal carcinoma presented with subacute onset of difficulty in speaking and involuntary movements of her tongue approximately 12 years after radiation therapy to head and neck. Electromyography displayed myokymic discharges. There was no evidence of recurrent malignancy. SIGNIFICANCE: Delayed effects of radiation therapy might be seen decades later. Myokymic discharges may reveal radiation-induced neuropathy.
RESUMEN
Endothelin-1 (ET-1) is a vasoconstrictor peptide derived from endothelium. Many authors have shown that ischemic stroke is associated with elevated plasma ET-1 levels. Also, the present findings related to plasma ET-1 levels with clinical status, size of the infarction, location of the infarction, and prognosis of the cerebral infarction were contradictory. In this study, plasma ET-1 levels in 30 patients with cerebral infarction within 72 hours after the onset of focal neurologic deficit and at their seventh day postinfarction were measured by a microplate enzyme immunoassay. Thirty sex- and age-matched healthy subjects were accepted as a control group. The mean plasma ET-1 concentrations in patients on admission, in patients at day 7, and in control subjects were 1.93 +/- 1.79, 1.03 +/- 1.02, and 0.65 +/- 0.32 fmol/mL, respectively. The mean plasma ET-1 level of patients on admission was found to be significantly higher than in patients at day 7 and in control subjects (p < 0.05). No significant difference in ET-1 levels was observed between the patients at day 7 and control subjects. Furthermore, there was no correlation between plasma ET-1 concentration and size of infarction, location of infarction, degree of clinical neurologic deficit, or prognosis of cerebral infarction. It was concluded that plasma ET-1 levels shortly after ischemic stroke were increased, which may be associated with the acute-phase reaction of cerebral infarction and may have deleterious effects on development of neuronal injury.
