AIM The aim of the present study was to develop a functional oral health literacy (OHL) instrument for adults, including new measures of literacy skills (OHL Adults Questionnaire: OHL-AQ). METHODS An item pool was provided, and an expert panel evaluated the items by assessing the content validity index and content validity ratio. The reliability analysis,(More)
BACKGROUND The majority of young children receive no early dental examination while attending primary health care for routine check-ups. Our aim was to study primary care nurses' knowledge of oral health care (OHC) and their attitudes toward delivering OHC, as well as to assess their willingness to obtain OHC information. METHODS We conducted a(More)
Selective immunoglobulin A deficiency (SIgAD) is the most common predominantly antibody deficiency, with a wide range of presentations from asymptomatic to severe manifestations. Although many studies have investigated different aspects of SIgAD, no study has yet presented a comprehensive classification of this disease. Based on clinical manifestation of(More)
BACKGROUND Schools can be an important setting for health education programmes, controlling the growing burden of oral diseases and promoting oral health. Aim. The aim of this study was to evaluate the short-term effect of school-based educational intervention on oral cleanliness and gingival health of 15-year-olds in Tehran, Iran. DESIGN The present(More)
A large number of sequence-specific SSRs were screened by using electrophoresis on metaphore agarose gels with the bands visualized by ethidium bromide staining. Many SSRs appeared as codominant and many as dominant markers, with presence or absence of bands. A simple Mendelian inheritance pattern for most codominant and dominant SSR loci was found. For(More)
Common variable immunodeficfiiency (CVID) is a primary immunodeficiency syndrome representing a heterogeneous set of disorders resulting mostly in antibody deficiency and recurrent infections. However, inflammatory and autoimmune disorders and some kinds of malignancies are frequently reported as a part of the syndrome. Although it is one of the most(More)
Selective immunoglobulin A deficiency (SIgAD) is the most common primary antibody deficiency. Although more patients with SIgAD are asymptomatic, selected patients suffer from different clinical complications such as pulmonary infections, allergies, autoimmune diseases, gastrointestinal disorders and malignancy. Pathogenesis of SIgAD is still unknown;(More)
BACKGROUND Common variable immunodeficiency (CVID) is characterized by a deficiency in the immune system with a heterogeneous collection of disorders resulting in antibody deficiency and recurrent infections. T helper 17 (Th17) cells promote B-cell survival and synergize with the B-cell activating factor to induce their differentiation into the plasma(More)
Primary immunodeficiency diseases (PID) are a genetically heterogeneous group of more than 270 disorders that affect distinct components of both humoral and cellular arms of the immune system. Primary T cell immunodeficiencies affect subjects at the early age of life. In most cases, T-cell PIDs become apparent as combined T- and B-cell deficiencies.(More)
Asthma is a reversible airway obstruction that is characterized by constriction of airway smooth muscle, hyper secretion of mucus, edema and airway hyper responsiveness (AHR), mucus secretion and thickening of the basement membrane underlying the airway epithelium. During the process of airway inflammation, complex interactions of innate and adaptive immune(More)
