  ABSTRACT: The aim of this research was to determine the risk for family appearance of the recurrent headache (non-migraine and migraine). The research was conducted in Vojvodina, the Northern Province of Serbia. The population of Vojvodina is around 2 million people belonging to more than 20 different ethnic groups. During the 20-year period (1988-2008), 30,363 children aged 3 to 17 years were tested, independent of their place of birth. The presence of headaches similar to those tested was compared among all the members of the family within three generations. Positive family data of the recurrent headaches were detected among 98.6% children with migraine headaches, 64.7% children with non-migraine headaches, and 32.4% children without recurrent headaches. The relation among the members of the nuclear family (contingency quotient of 0.429) was significantly stronger than the relation to the members of wider family (contingency quotient of 0.338). The probability of a child having the migraine headache rather than the non-migraine one was very high for parents and high for father's mother, while it was not significant for mother's mother, mother's father and father's father, having similar recurrent headaches.

  ABSTRACT: The purpose of this study was to investigate the effects of treatment with water, n-butanol and ether extracts of Hypercom perforatum L. on epileptogenesis in rabbits. Animals from the control group received solvent-ethanol, and the kindling model of epilepsy was used. Epileptic focus was induced in Chinchilla rabbits by stimulation of the hippocampus. The following parameters were determined: the minimum current strength necessary to induce after-discharge (AD) - discharges appearing after cessation of stimulation; AD duration; the number of stimulations necessary to induce spontaneous kindling; and the latency time for the development of full kindling. The results obtained indicate that epileptogenesis is influenced by Hypericum perforatum L. extract treatment. Animals treated with an ether extract of Hypericum perforatum L. required significantly weaker minimum current strengths for the development of epileptogenic focus, and displayed longer AD times, while the number of electro-stimulations necessary for full kindling was less. In contrast, animals treated with water and n-butanol extracts required increased electro-stimulations for the development of epileptic discharge, and displayed shortened AD durations versus controls.

  ABSTRACT: To assess the incidence of children with various types of migraine, an investigation was carried out from 1988 to 2008, on 30636 children (50.38% male, 49.62% female), in nine towns of the north province of Serbia. Migraine was reported in 8.63% children aged 3 to 17 (8.0% male, 9.6% female) as well as in 3.87% children aged 3-7 (4.2% boys, 3.57% girls). The proportion of children with either migraine or non-migraine headaches increased with their age, from 2.65% to 11.72% in boys, and from 2.71% to 15.86% in girls. Such increasing trend was also found for migraine with aura (from 1.8% to 32.7%). Children with migraine with aura showed their pick at the age of 9, while other migraine syndromes had the most frequent appearance at the age of 5 years. Migraine with aura accounted for 25.55%, migraine without aura for 67.21% and other migraine syndromes for 7.23% of investigated subjects with migraine. The average age of the migraine diagnosis was 5 years 1.8 months, while it was 4 years 11.4 months for migraine with aura, 5 years 7.2 months for migraine without aura and 3 years 7.2 months for other migraine syndromes. Migraine is much more frequent in second born children and in these from incomplete families. Migraine with aura appeared mostly in children coming from family with median socioeconomic welfare, while poor family welfare was predominant in children with migraine without aura. The length of breast-feeding influenced the appearance of the migraine in general, showing reciprocal influence of the length of breast-feeding on the appearance of migraine. Migraine was more often found (39.4%) among children who earlier joined nursery schools on a whole-day stay basis. Children with migraine have been diagnosed and treated by neuropaediatricians or neurologists in 55.4% cases (70.0% migraine with aura, 42.7% migraine without aura and 92.4% children with other migraine syndromes).
