Parents’ knowledge of and opinions about healthcare laws and technology in primary care

Purpose Historically, parents have demonstrated poor understanding of adolescent healthcare laws. This study assessed US parents’ current knowledge and opinions about technology facilitated physician–adolescent communication and applicable laws to enhance transition to adult health care.Methods A brief survey in two low-income academic paediatric clinics asked parents about their knowledge of health care and laws, and their opinions about technology facilitated contact between physicians and adolescents.Results Almost all parents (96.7%) have internet access at home, work or via a mobile device. Only 44.1% approved of having a physician directly contact their child about annual examinations, immunisations or to discuss issues of sexuality. Half (55.4%) were aware that adolescents could receive confidential sexuality information and treatment without parents’ permission. Only one-third (32.2%) approved of a specific technology for direct communication.Conclusions Parents are divided about direct physician–adolescent contact. Future plans to engage adolescents to understand their health will require parental education and involvement on the value of physician–adolescent communication

Genotyping the GGGCGG Tandem Repeat Promoter Polymorphism in the 5-Lipoxygenase Enzyme Gene (ALOX5) by Pyrosequencing Assay

Aims: Efficient genotyping methods for many biologically significant repeat genetic polymorphisms, particularly in GC-rich regions of the genome, are limited. In particular, a short tandem repeat polymorphism [GGCGGG] in the promoter region of ALOX5 has been implicated as an important marker for inflammatory diseases. We developed a pyrosequencing assay to genotype the ALOX5 short tandem repeat polymorphism using pyrosequencing technology that will make assessing this important genetic marker in large, diverse populations more accessible than using current methods. Materials and Methods: We used a nested polymerase chain reaction approach to amplify DNA for pyrosequencing. Population allele frequencies were assessed in two cohorts of previously collected human DNA samples with 188 and 1032 samples, respectively. Sixteen genetic samples with known genotypes were used to confirm the accuracy of the method. Results and Discussion: Genotypes were 100% concordant with samples of known genotype. Genotype frequencies in European American, Hispanic, and African American agreed with previously published results (wild-type homozygotes 66%, 64%, and 19%, respectively). The method presented here will facilitate both genetic association and pharmacogenomic research on this polymorphism in large samples that are ethnically and/or racially admixed
