There is a growing body of evidence implicating inflammatory cytokines and brain-derived neurotropic factor (BDNF) in the generation of migraine pain. No previous study evaluated BNDF levels during migraine attacks and there are conflicting results regarding tumor necrosis factor-alpha (TNF-alpha) serum levels. This study compared serum levels of TNF-alpha, soluble TNF receptors 1 and 2 (sTNF-R1 and sTNF-R2), and BDNF during migraine attacks and in headache-free periods. ⋯ BDNF serum levels were significantly higher during migraine attack than in pain-free period. This is the first report showing that BDNF serum levels increase during migraine attack. This reinforces the view that BDNF may be implicated in the physiopathology of migraine.

No guidelines for performing and presenting the results of studies on patients with medication overuse headache (MOH) exist. The aim of this study was to review long-term outcome measures in follow-up studies published in 2006 or later. We included MOH studies with >6 months duration presenting a minimum of one predefined end point. ⋯ Medication days/month and change in headache index at the end of follow-up were reported in only one and two of nine studies, respectively. The present review demonstrated a lack of uniform end points used in recently published follow-up studies. Guidelines for presenting follow-up data on MOH are needed and we propose end points such as headache days/month, medication days/month, relapse rate and responder rate defined as ≥50% reduction of headache frequency and/or headache index from baseline.

Pheochromocytoma is a well known, catecholamine-producing tumor characterized by hypertension, headache, hyperglycemia, hypermetabolism, and hyperhydrosis. Approximately 65% of cases of pheochromocytoma were shown to be associated with hypertension. A case of pheochromocytoma that presented with thunderclap headache (TCH) and palpitations is reported. ⋯ According to the International Classification of Headache Disorders (ICHD)-II, headache attributed to pheochromocytoma usually develops concomitantly with an abrupt increase in blood pressure. In our case, however, hypertension was never observed, even when the patient was symptomatic. This is the first report of a case of pheochromocytoma with TCH without hypertension.

In a controlled trial to evaluate the effectiveness of a simple educational and physical program administered to a large cohort of public servants, we previously found that 6 months following treatment the monthly frequency of headache and neck and shoulder pain and drug intake was reduced by 40% in the experimental compared with controls. These results were stable at a 12-month follow up. The program consists of brief shoulder and neck exercises to be performed several times a day, a relaxation exercise, and instructions on how to reduce parafunction and hyperfunction of the craniofacial and neck muscles during the day. ⋯ Days per month with headache at the baseline and at the end of intervention period were 6.40 and 4.58 (mean change -1.81, p < 0.0001), respectively; days with neck and shoulder pain were 7.48 and 6.18 (mean change -1.30, p = 0.0179); days of analgesic consumption were 1.67 and 1.17 (mean change -0.50, p = 0.0222). The responder rate was 42.3% for headache, 42% for neck and shoulder pain and 58.3% for drug consumption. In conclusion, this study adds further evidence on the efficacy of our program and its high acceptability in a large, unselected, working population.
