Background. There is a mismatch between presenting concerns of adolescents to GPs and behaviours that lead to adolescent morbidity and mortality. Better understanding of health concerns of this target group would enhance communication between health professionals and adolescent patients.

Objective. To explore and categorize the health concerns of adolescent girls sending unsolicited emails to a teenage girls’ magazine.

Method. We conducted a content analysis of 1000 systematic randomly selected unsolicited emails submitted to the health column of an Australian adolescent girls’ magazine over a 6-month period.

Results. Three main foci of concern were identified: Context of Concern, Health Issue of Concern and Advice Sought for Concern. Within Health Issue of Concern, there were five categories: body (47.5%), sex (31.9%), relationship (14.7%), mind (4.7%) and violence and/or safety (1.2%). Concerns within the body and sex categories ranged enormously, but frequently expressed intimate descriptions of anatomy, feelings, sexual practices and relationships. Many concerns occurred in the context of adolescents’ relationships with others. The proportion of concerns about physical or psychological symptoms or health issues commonly associated with the adolescent age group (such as health risk behaviours, mental health, pregnancy and sexually transmitted infections) was relatively small.

Conclusions. GPs and other health professionals might engage more readily with adolescent patients with a deeper understanding of the concerns that adolescents have about their bodies, relationships and overall health. Seemingly ‘trivial’ issues, such as normal puberty, could be used as discussion triggers in health consultations to help alleviate anxiety and build rapport.

X-linked deafness type 3 (DFN3), the most prevalent X-linked form of hereditary deafness, is caused by mutations in the POU3F4 locus, which encodes a member of the POU family of transcription factors. Despite numerous reports on clinical evaluations and genetic analyses describing novel POU3F4 mutations, little is known about how such mutations affect normal functions of the POU3F4 protein and cause inner ear malformations and deafness. Here we describe three novel mutations of the POU3F4 gene and their clinical characterizations in three Korean families carrying deafness segregating at the DFN3 locus. The three mutations cause a substitution (p.Arg329Pro) or a deletion (p.Ser310del) of highly conserved amino acid residues in the POU homeodomain or a truncation that eliminates both DNA-binding domains (p.Ala116fs). In an attempt to better understand the molecular mechanisms underlying their inner ear defects, we examined the behavior of the normal and mutant forms of the POU3F4 protein in C3H/10T1/2 mesodermal cells. Protein modeling as well as in vitro assays demonstrated that these mutations are detrimental to the tertiary structure of the POU3F4 protein and severely affect its ability to bind DNA. All three mutated POU3F4 proteins failed to transactivate expression of a reporter gene. In addition, all three failed to inhibit the transcriptional activity of wild-type proteins when both wild-type and mutant proteins were coexpressed. Since most of the mutations reported for DFN3 thus far are associated with regions that encode the DNA binding domains of POU3F4, our results strongly suggest that the deafness in DFN3 patients is largely due to the null function of POU3F4.
