The prevalence of primary headache disorders in the adult population of Estonia.

OBJECTIVE: To estimate the one-year prevalence of primary headaches, most importantly migraine and tension type headache, but also other primary headaches, in Estonia. METHODS: A population-based random sample of 2162 subjects in Tartu City and Tartu County were interviewed by telephone or face to face using a previously validated questionnaire. RESULTS: Of the 2162 contacted participants, 1215 (56%) fully completed the study. Of these, 502 (41.3%) reported headache during the previous year. The prevalences adjusted by weighting by age, gender, education, marital status and habitat were the following: All headaches 41.0%, all migraine 17.7%, all tension-type headache 18.0%, trigeminal autonomic cephalalgias 0.4%, other primary headaches 2.5%, and chronic headaches 2.7%. CONCLUSION: The 1-year prevalences of primary headache disorders in Estonia are comparable to the previous findings in other European countries.

Symptomatic Neonatal Arterial Ischemic Stroke With Prenatal and Postnatal Neuroimaging.

The authors report a girl born at term via planned cesarean delivery. Three days earlier, an antenatal magnetic resonance imaging study, showing no cerebral lesions in the fetus, was performed. Ten minutes after delivery, signs of progressive respiratory failure developed and the infant was transferred to the intensive care unit. On the next day, a computed tomography (CT) scan showed acute ischemic lesions in the areas of the left middle and posterior cerebral arteries. The exact mechanism of stroke remained unidentified. It is possible that emboli occluded the left middle cerebral artery and left posterior cerebral artery. At the age of 1 year and 4 months, the patient demonstrated a slight right-sided hemiparesis more pronounced in the hand. To our knowledge, there are no prior published case studies reporting a healthy fetal brain, which then undergoes an acute neonatal arterial infarction near or during birth following an elective cesarean delivery.
