The majority of previous studies on headache in children and adolescents have focused mainly on migraine. There is a paucity of population-based studies investigating the prevalence of tension-type headache (TTH). The objectives of the present study were to estimate the prevalence of migraine and TTH in adolescents using the 2004 International Headache Society (IHS) criteria and to determine the sociodemographic and clinical differences between the migraine and TTH. ⋯ Migraine and TTH were found to be common types of headaches in adolescents. It was thought that, with the use of modified IHS criteria, the number of undiagnosed patients with headache will decrease.

The purpose of the present paper was to investigate the relationship between Helicobacter pylori infection and clinical symptomatology, breast-feeding and socioeconomic level. The relationship between H. pylori and iron-deficiency anemia (IDA) and the effect of H. pylori infection on growth were also investigated. ⋯ Low socioeconomic status seems to be an important risk factor for H. pylori infection. Exclusive breast-feeding at least for 4 months can have a protective role against H. pylori infection. Increased frequency of growth retardation and IDA in H. pylori-infected patients in the present study supports similar findings in the literature, although there is still need for detailed studies to clarify the causative mechanisms.
