“…Comparing with the normal weight group (32%), the prevalence was higher in overweight children (39%; odds ratio [OR] 1.35, 95% confidence interval [CI] 0.51‐3.61) and even higher in the obese group (52%; OR 2.25, 95% CI 0.99‐5.12). Metabolic syndrome was found in 25%, and patients with the syndrome did not have higher prevalence of headache (52% vs 45%); (3) In adults, the metabolic syndrome does not appear to influence headache prevalence in obese patients; (4) A score to differentiate migraine from tension‐type headache was established, using 536 headache attacks reported by 121 nurses during a 2‐month follow‐up; (5) 14 new cases of corpalgia in migraine patients were described; (6) The continuous prophylactic use of propranolol, amitryptiline, or simvastatin in migraineurs decreases both the frequency of headache attacks and the production of nitric oxide in the blood; (7) Vitamin B6 has a preventive effect on menstrual migraine when used at a dose of 600 mg/day from the 14th day until menstruation; (8) Clinical symptomatology of the postdural puncture headache and risk factors were evaluated in 640 raquianesthesias; (9) Melatonin‐induced analgesia in addition to inhibiting neoplasic growth using a mouse or rat as the animal model; (10) The history of primary headache is a risk factor of headache related to hemodialysis (52% vs 12%); (11) A descriptive, comparative, cross‐sectional study with 110 postmenopausal women (recent [<5 years] vs late [≥5 years]) showed that the recent postmenopausal group presented highest average scores in the memory/concentration, vasomotor symptoms, and attractiveness domains in the Women's Health Questionnaire for assessment of their quality of life; (12) Prior history of headache is a risk factor of postmastectomy pain (OR 1.92; 95% CI: 1.10‐3.34); (13) Sentinel headache, as warning sign of subarachnoid hemorrhage due to ruptured intracranial aneurysm, was present in 18% of the patients; (14) The characteristics of head pain in response to an experimental cold stimulus to the palate in 414 volunteers were described; (15) Chronic posttraumatic headache after mild traumatic brain injury is similar to migraine in women; (16) There was migraine remission in 35%, 77%, 79%, respectively, in the first, second, and third trimesters among migraine without aura sufferers during pregnancy, and exclusive breastfeeding was associated with a lower chance of migraine recurrence at the first postpartum month; (17) Perfumes, paints, gasoline, and bleach are the most frequent odorants that trigger migraine attacks; Osmophobia predominated in patients with migraine and may be a specific maker to differentiate migraine from tension‐type headache; (18) In a population of 726 children and adolescents, headache was significantly associated with myopia (OR 2.67), hyperopia (OR 3.10), astigmatism (1.86), and strabismus (5.21); (19) Water deprivation is associated with increase of pain in the head in rats; (20) In a study involving 417 university students, 53% of them mentioned they ha...…”
