ABSTRACT
Multiple sclerosis (MS) is an inflammatory demyelinating disease of the central nervous system and is the most common cause of neurologic disability in young adults. In this study, the coagulation status and biochemical and non-specific inflammatory markers in patients with MS were investigated. Plasma prothrombin time, activated partial thrombin time, fibrinogen, D-dimer, serum high sensitive C-reactive protein, homocysteine, blood urea nitrogen, creatinine, calcium, total protein, albumin, total cholesterol, vitamin B12, folate levels and erythrocyte sedimentation rate were measured in 42 patients with MS and 31 healthy subjects as a control group. There was a positive correlation between homocysteine and D-dimer levels (r=0.84, p<0.01). However, there was no significant correlation between homocysteine, vitamin B12 (r=0.18) and folate (r=0.23) levels. Serum total protein, albumin and calcium levels of MS patients were lower than the control group. There are some alterations in the coagulation and biochemical status in MS patients. These findings may contribute to better understanding of the etiopathogenesis and clinical characteristics of this disease.

OBJECTIVE: This epidemiological survey was conducted to investigate comprehensive characteristic and overlapping features of migraine and tension-type headache (TTH) disorders classified based on International Classification of Headache Disorders-II. METHODS: The stratified cohort of this study was composed of 2504 schoolchildren aged 10 to 17 years. A 38-item questionnaire inquiring all characteristic features of primary headache syndromes mandatory for classification was applied to selected 483 children with recurrent headache in the last 6 months. RESULTS: Migraine was diagnosed in 227 (47.0%) of 483 children and TTH in 154 (31.9%). Out of 125 children with definite migraine, 73 (58.4%) reported tension-type symptoms and 94 (68.1%) of 138 children with definite TTH reported migraine-type symptoms. Pressing pain (21%) and lack of aggravation of pain by physical activity (34%) were the major tension-type features in patients with migraine. Throbbing quality (43%) and aggravation by physical activity (30%) determined the main migraine-type features in patients with TTH. CONCLUSION: The frequent co-occurrence of migraine and TTH symptoms suggests the presence of a common pathogenesis.

Familial hemiplegic migraine (FHM) is a rare autosomal dominantly inherited subtype of migraine, in which hemiparesis occurs during the aura. The majority of the families carry mutations in the CACNA1A gene on chromosome 19p13 (FHM1). About 20% of FHM families is linked to chromosome 1q23 (FHM2), and has mutations in the ATP1A2 gene, encoding the alpha2-subunit of the Na,K-ATPase. Mutation analysis in a Dutch and a Turkish family with pure FHM revealed two novel de novo missense mutations, R593W and V628M, respectively. Cellular survival assays support the hypothesis that both mutations are disease-causative. The identification of the first de novo mutations underscores beyond any doubt the involvement of the ATP1A2 gene in FHM2.

The effects of botulinum toxin have been demonstrated in pain syndromes such as migraine, tension headache, and postherpetic neuralgia. With this background data in hand, the authors planned a randomized, open-ended study to investigate the efficacy of botulinum injections in cases of refractory trigeminal neuralgia. In 8 patients with trigeminal neuralgia, 100 U botulinum toxin was injected into the region of the zygomatic arch. The results of their statistical analyses demonstrated that the medication can be effective in treating trigeminal neuralgia. The patients did not develop any significant adverse effects. Botulinum toxin can be used in the treatment of refractory trigeminal neuralgia.
