Although migraine is a neurological disorder known since long, its physiopathology remains unclear. Recent studies suggest that migraine is associated with oxidative stress; however, they report divergent results. The aim of the present study was to evaluate total antioxidant status (TAS), total oxidant status (TOS), oxidative stress index (OSI), and serum thiol level in migraine patients with or without aura. The study group consisted of 141 migraine patients. The control group included 70 healthy subjects. TAS, TOS, OSI were evaluated using a method developed by Erel. Serum thiol level was measured using the Hu method. No difference was found in TAS, TOS, OSI between the patients and controls. The level of thiol was significantly lower in patients than in controls. Negative correlations were detected between thiol level and Migraine Disability Assessment score in patients. Although TAS, TOS, and OSI were similar to those of the control group, serum thiol level, an important marker of antioxidant capacity, was significantly lower in migraines compared with controls, and caused more serious disability. Novel treatment approaches may be developed based on these data, and compounds containing thiol, such as alpha lipoic acid and N-acetyl cysteine, may be used in prophylaxis.

The average RNFL thickness in the migraine patients was found to be thinner than that in the control group. In addition, we found a negative weak correlation between length of migraine history and the average RNFL thickness, supporting the possible association between these pathologies.

We evaluated swallowing function in patients with myasthenia gravis (MG) with or without dysphagia symptoms using different evaluation parameters and compared the results with those of healthy subjects. A total of 36 patients with MG and 25 healthy volunteers were included in the study. The subjects were classified into three groups; patients without dysphagia (group 1), patients with dysphagia (group 2), and healthy participants (group 3). The presence and severity of dysphagia, the oropharyngeal, pharyngeal, pharyngoesophageal, and esophageal phases were assessed using a screening test, manometric test, electrophysiologic studies [electroneuromyography (EMG)], fiberoptic endoscopic evaluation of swallowing (FEES), and barium swallow pharyngeal esophagography (BSPE), respectively. There was a significant difference between group 1 and group 3 in terms of BSPE (p = 0.001) and manometry tests (p = 0.001). A significant difference was found in all methods between group 2 and group 3 (p = 0.001, for all). In the comparison of the patient groups, although the number of patients with dysphagia in group 2 was significantly higher in the clinical tests (p = 0.007), FEES (p = 0.001), and EMG (p = 0.043) than in group 1, no difference was detected for BSPE (p = 0.119) and manometry (p = 0.644). Swallowing functions in patients with MG may be affected even without symptoms. This condition should be considered in their follow-up.

In our study, the prevalence of hypercementosis has been found 2.4% in the Turkish population. Besides, the lesion has been found more in the mandible than the maxilla, in the molars than the premolars and in the unilateral distribution than the bilateral distribution.
