RESUMO
Objectives: The objectives of this study were to determine the prevalence of attention deficit hyperactivity disorder [ADHD] and specific parental risk factors that may contribute to the development of ADHD in children
Methods: The study was conducted in Oman among fourth-grade students [aged nine to 10 years]. A standardized Arabic version of the National Initiative for Children's Health Quality Vanderbilt Assessment Scale [Teachers questionnaire] was used to determine the presence of ADHD. Parental factors such as socioeconomic status, education, and occupation were documented
Results: The prevalence rate of ADHD was 8.8%. Poor maternal education status, low familial socioeconomic status, and paternal occupation were significantly associated with an increased risk of ADHD
Conclusions: This was the first study that examined familial and parental characteristics of children with ADHD as potential risk factors for the condition. Such psychosocial factors could be employed to further the development of more proficient preventative measures and remedial services
RESUMO
To determine the frequency of different HLA- antigens in patients with plaque psoriasis in the Omani Arab population. Fifty four Omani patients clinically diagnosed with plaque psoriasis attending the dermatology outpatient clinic in Al-Nahdah Hospital [the tertiary dermatology centre in Oman] were selected for HLA studies. HLA-B52 was present in 20.4% of patients 11/54 and in 5% of controls without psoriasis 5/100. For the association p was <0.004 and the relative risk [RR] was 4.86. Psoriasis does not appear to be associated universally with the same HLA antigens. The association of HLA-B52 with plaque psoriasis in Omani patients compares with the HLA- Cw6, -Bw57 and -DR7 preponderance in most other ethnic groups
