Tuberous sclerosis complex: clinical features, diagnosis, and prevalence within Northern Ireland

Tuberous sclerosis complex (TSC) is an autosomal dominant disorder caused by mutations in the TSC1 and TSC2 genes on chromosomes 9 and 16 respectively. Diagnosis is based on clinical features but can be difficult as a result of variable phenotypic expression. With the advantage of mutation analysis in making a diagnosis of TSC, and improved identification of the associated clinical features, there have been few new data on its prevalence and on the proportion of cases due to new mutations. We have performed a retrospective epidemiological study on the prevalence of TSC, the clinical features attributed to it, and the availability of mutational analysis. We identified 73 known patients with TSC (5 deceased): 39 were female and 34 male. Ages ranged from 10 months to 69 years, with a mean age of 27 years 11 months (SD 16y 10mo). The point prevalence of TSC in our study was estimated at I out of 24 956 on the prevalence day (30 April 2004). The majority of patients (42.5%) were diagnosed at less than 15 months of age; 25% were not given a diagnosis on first developing symptoms. In all, 93.2% had epilepsy and 71.2% had a learning disability.* A mutation was identified in 95.8% of those tested (26% TSC1 and 74% TSC2). TSC2 mutations were correlated with a more severe phenotype. The new mutation rate was calculated at 64%. We conclude that the prevalence of TSC is higher than previously calculated. We recommend that all children with epilepsy be assessed for features of TSC. Larger studies will be required to assess the prevalence of mutations in each gene, and genotype-phenotype correlation.

War, peace and suicide: The case of Northern Ireland

Durkheim’s idea that war reduces suicide through greater social and political integration has been used to explain suicide trends during the Northern Ireland conflict and in the period of peace. The applicability of Durkheim is critically evaluated through a case study of suicide trends by age, gender and cause of death over a forty year period. The key finding is that the cohort of children and young people who grew up in the worst years of violence during the 1970s, have the highest and most rapidly increasing suicide rates, and account for the steep upward trend in suicide following the 1998 Agreement. Contrary to Durkheim, the recent rise in suicide involves a complex of social and psychological factors. These include the growth in social isolation, poor mental health arising from the experience of conflict, and the greater political stability of the past decade. The transition to peace means that externalised aggression is no longer socially approved. It becomes internalised instead.

Intimate Mixing - Bridging the Gap? Catholic-Protestant Relationships in Northern Ireland

For many years Northern Ireland has been a divided society where members of the two main religious groups, Catholics and Protestants, have limited opportunities to interact due to segregation in their social lives. Attempts have been made to encourage religious mixing through integration in schools, housing and workplaces predicated on the theory that bringing people together can improve community relations and remove prejudices – known as the ‘contact hypothesis’. However, little is known about those who enter into mixed-religion partnerships often against the wishes of their families and communities. This paper examines the characteristics and attitudes of mixed-religion couples and suggests that they differ in their socio-demographic characteristics and in their attitudes from those who marry within their own religion. These findings add to the weight of evidence from other countries in conflict suggesting that intermarriage has a role to play in contributing to less sectarian views and improved community relations.

Barriers to increasing fruit and vegetable intakes in the older population of Northern Ireland: low levels of liking and low awareness of current recommendations

Objective: To investigate barriers to increasing fruit and vegetable (f + v) intakes in a large sample of the older population of Northern Ireland (NI), in relation to current intakes.
