Background Cleft lip and palate(CL/P)is the most common orofacial malformation affecting one in every 700–1000 newborns worldwide. The aim of the study wasto evaluate the impact of CL/P on health- related quality of life (OHRQoL) in Sudanese children and the level of concordance between caregivers' and children and to investigate correlates of the caregivers' perceptions of OHRQoL with that of their children. Methods The sample consisted of 75 children with clefts (age range 8–16 years), (46 male, 29 female) and their caregivers' attending University of Science and Technology Dental Teaching Hospital. The children and their caregivers' were interviewed separately. The interview consisted of 38 questions adopted from the COHIP (Arabic version).The level of concordance between caregivers' and children was compared using paired t-tests and intraclass correlations. Predictive validity was assessed using Pearson correlations and linear regression analyses. Results The translated COHIP and its subscales, had Cronbach' alphas score ranged between (0.65 and 0.75) for caregivers' and children with cleft. COHIP scores for children and caregivers' were (89.41 ± 19.97) and (94.34 ± 19.52) respectively. Caregivers' and children differed significantly in the overall COHIP and oral symptoms subscale. There were high correlations between caregivers' and children ranged from (0.63 to 0.87). The correlation between all subscales was statistically significant (p = 0.05). Conclusions Caregivers' had higher perceptions of oral symptoms and overall COHIP compared to their children using the Arabic version of the COHIP. Caregiver's reports have to be considered complementary to the reports of their children themselves.

ObjectivesFrom the first description by Leo Kanner [1], autism has been an enigmatic neurobehavioral phenomenon. The new genetic/genomic technologies of the past decade have not been as productive as originally anticipated in unveiling the mysteries of autism. The specific etiology of the majority of cases of autism spectrum disorder (ASD) is unknown, although numerous genetic/genomic variants and alterations of diverse cellular functions have been reported. Prompted by this failure, we have investigated whether the metabolomics approach might yield results which could simultaneously lead to a blood-based screening/diagnostic test and to treatment options. Methods Plasma samples from a clinically well-defined cohort of 100 male individuals, ages 2-16+ years, with ASD and 32 age-matched typically developing (TD) controls were subjected to global metabolomic analysis. ResultsWe have identified more than 25 plasma metabolites among the approximately 650 metabolites analyzed, representing over 70 biochemical pathways, that can discriminate children with ASD as young as 2 years from children that are developing typically. The discriminating power was greatest in the 2-10 year age group and weaker in older age groups. The initial findings were validated in a second cohort of 83 children, males and females, ages 2-10 years, with ASD and 76 age and gender-matched TD children. The discriminant metabolites were associated with several key biochemical pathways suggestive of potential contributions of increased oxidative stress, mitochondrial dysfunction, inflammation and immune dysregulation in ASD. Further, targeted quantitative analysis of a subset of discriminating metabolites using tandem mass spectrometry provided a reliable laboratory method to detect children with ASD. Conclusion Metabolic profiling appears to be a robust technique to identify children with ASD ages 2-10 years and provides insights into the altered metabolic pathways in ASD, which could lead to treatment strategies. ObjectivesTo uncover novel traits associated with nicotine and alcohol use genetics, we performed a phenome-wide association study in a large multi-ethnic cohort. Methods We investigated 7,688 African-Americans (AFR), 1,133 Asian-Americans (ASN), 14,081 European-Americans (EUR), and 3,492 Hispanic-Americans (HISP) from the Women's Health Initiative, analyzing risk alleles located in the CHRNA5-CHRNA3 locus (rs8034191, rs1051730, rs12914385, rs2036527, and rs16969968) for nicotine-related traits and ADH1B (rs1229984 and rs2066702) and ALDH2 (rs671) for alcohol-related traits with respect to anthropometric characteristics, dietary habits, social status, psychological circumstances, reproductive history, health conditions, and nicotine-and alcohol-related traits. ResultsThe investigated loci resulted associated with novel traits: rs1229984 were associated with family income (p=4.1*10 −12 ), having a pet (p=6.5*10 −11 ), partner education (p=1.8*10 −10 ), "usually expect the best" (p=2.4*10 −7), "felt calm and peaceful" (p=2.6*10 ), and num...

Objective: This study compared the oral health-related quality of life (OHRQoL) among children with a cleft lip with or without a cleft palate (CL±P) and a group of their peers. The reliability of the Arabic version of the Child Oral Health Impact Profile Questionnaire (COHIP) was also assessed. Design: A cross-sectional study. Settings: Cleft clinic in a private dental college in Omdurman City, Sudan. Patients: In all, 75 children (mean age 11.3 ± 2.5 years) with a history of CL±P and a group of 150 school children without CL±P (mean age 11.4 ± 2.6 years). Main Outcome Measures: Overall and subscale scores on the Arabic version of the COHIP. Results: Test–retest reliability of COHIP in Arabic was high with an interclass correlation coefficient >0.8. Cronbach α value internal consistency was 0.8 for the total scale and between 0.7 and 0.8 for the subscales. The COHIP score was 89.41 ± 19.97 in children with CL±P and 122.82 ± 9.45 for the control group. Children with CL±P had significantly lower scores on the overall and all subscales when compared to children without CL±P ( P ≤ .001). Among the children with CL±P, there were no statistically significant differences on the COHIP based on age and/or gender ( P ≥ .05). Conclusions: Children with CL±P had a relatively high OHRQoL, which was lower than that of their peers without CL±P in both the overall scale and all subscales. Gender and age differences had no significant impact on the OHRQoL. The COHIP Arabic version showed appropriate reliability.
