Přihlášení Registrace

The effect of voluntary hyperventilation was assessed in 22 cluster headache patients (8 in a cluster period and 14 in a remission) and 19 healthy individuals. Using an ear oximeter and a capnograph with a nasal probe, the oxygen saturation (SaO2) and the end-tidal CO2 were monitored continuously.

The comparison of two groups of migrainous patients with or without hyperventilation syndrome (HS) provided the conclusions that HS provokes more severe migrainous attacks and psychovegetative symptoms in migrainous cephalalgia (MC). The findings also support the existence of stem structure

Twenty-eight cluster headache patients were examined either in remission (n = 10), in the interparoxysmal period ("cluster phase") (n = 12), or during spontaneously occurring (n = 7), or nitroglycerin provoked (n = 7) attacks. Fourteen healthy controls participated in the study. Oxygen saturation

Using the method of rheoencephalography 182 children aged 8 to 16 years and suffering from functional headaches were examined. With regard to the clinical criteria they were divided into two groups: patients with migraine, and those with vasomotor headache. The control group consisted of 345

Widespread reduction of regional cerebral blood flow during hyperventilation-induced EEG slowing ('buildup'). Observation from subtraction of brain imaging with single photon emission computed tomography using technetium-99m hexamethyl-propyleneamine oxime.

To study the pathophysiological mechanisms of hyperventilation-induced EEG showing, i.e., the so-called 'buildup' phenomenon, changes in regional cerebral blood flow (rCBF) were investigated before and during the phenomenon in a 16-year-old woman with headache, thought to be of neurotic origin, by

The author describes three observations characterized by the following similar features: 1. Children, between 2 and 9 years, suffering from attacks of sterotyped headaches. 2. EEG with bursts of high- voltage paroxysmal discharges, mainly during hyperventilation. 3. Efficiency of antiepileptic drugs

Hyperventilation (HV) is an important activating procedure in clinical EEG. Paroxysmal HV slowing is associated with hypoglycemia and is common in children. Paroxysmal slowing in adults is sometimes interpreted as indicating cerebral instability or paroxysmal tendencies. We investigated the clinical

Ten cluster headache patients and 10 healthy controls were subjected to electrocardiographic and pupillometric procedures in a search for cardiac and pupillary sympathergic asymmetry. Sympathergic stimulation was provoked by hyperventilation and by instilling tyramine into both eyes. In the control

In cluster headache an adrenergic dysfunction of the pupillary sympathetic system can be demonstrated even during pain-free periods by instillation of tyramine in the conjunctival sac. In this study 10 patients with typical cluster headache syndrome exhibited a positive tyramine conjunctival test

Hyperventilation syndrome (HVS) often occurs under stressful conditions, and has been reported during or after anesthesia and operation. HVS, characterized by multiple somatic symptoms and electrolyte imbalances induced by inappropriate hyperventilation, should be managed as an emergency. We report
