background: asthma is a chronic multifactorial disease with a high prevalence. among asthma risk factors, the effect of baking in wood tenor ovens (traditional form of baking) on bronchial asthma is still debated. the aim of this study was to determine the association between baking in wood tenor ovens and incidence and control of bronchial asthma. materials and methods: this descriptive study ...

purpose: to determine the incidence and prevalence of clinical keratoconus (kcn) in yazd province. methods: in this population-based survey, a surveillance program was established in yazd province (population size=990,818). all new clinically diagnosed cases of kcn were registered and referred for topographic imaging during one year (2008-2009) by all local ophthalmologist and optometrists. peo...

background: evaluating the tuberculosis (tb) status of theeconomic cooperation organization (eco) member countriesrelation to goal 6-c of the third millennium, which includes thattb incidence, prevalence, and death rates should be halved by2015, compared with their level in 1990.methods: in 2009, we have critically reviewed the countries’millennium development goals (mdgs) reports and extracted...

it is estimated that one third of the world's population is latently infected with tuberculosis (tb). the hiv epidemic fuels the tb epidemic by increasing the risk of reactivation of latent tb infection and by facilitating a more rapid progression of tb disease. although the incidence of tb is constant or decreasing in many regions of the world, rates remain high in developing countries as a co...

demographic changes in germany show the fastest progress of all european countries and are not only influencing socioeconomic issues but also the management of patients with their individual risc profile. especially severely injured elderly constitute a group of patients who need specific attention due to their individual age related pathophysiological processes. 21% of the german population we...

purpose: to determine the incidence, concurrent factors and clinical results of re-operation after corneal refractive surgeries. methods: in this retrospective descriptive study records of all patients undergoing corneal refractive surgeries including prk, lasik, and lasek between april 2005 and december 2006 were assessed. patients who had undergone re-operations entered the study; visual acui...

this article was aimed to provide an overview and a perspective on the changing impact of cancers with increasing age on three age groups. a population based cancer registry was undertaken to register all new cancers cases from march 2006 to march 2007. during one year, 2023 (41.1%) of 4922 patients with cancer were ≥65 years. the five most common cancers (excluding skin cancer) were stomach, b...

Direct or Eley-Rideal reactions between energetic N^{+} and O^{+} projectiles and O atoms, adsorbed onto Pt and Pd surfaces, are studied experimentally at incidence energies between 20 and 200 eV. The exit energies of the diatomic molecular products NO and O_{2} depend linearly on the incidence energy of the corresponding projectiles. A reaction mechanism is proposed, where the incident project...
