Development and predictors of psychological outcomes following the 2008 earthquake in Iceland: a longitudinal cohort study.

AIMS: On 29 May 2008, an earthquake struck in South Iceland. The aim of this study was to explore the trajectories of post-traumatic stress, depressive and anxiety symptoms among exposed inhabitants during the first year following the earthquake, as well as predictors for symptomology. METHODS: This was a longitudinal cohort study based on a sample that was randomly selected from the earthquake-stricken area ( n = 1301). Participants answered a questionnaire assessing demographic and disaster-related factors 2 months after the earthquake. In addition, symptoms of post-traumatic stress disorder (PTSD), depression and anxiety were assessed 2, 4, 8 and 12 months post-disaster. RESULTS: Two months after the earthquake, 5.2% of the participants reported PTSD symptoms, 6.7% depression and 6.4% anxiety symptoms. When comparing first and last time points only, we found a significant decrease in anxiety ( p = 0.05), particulary among females ( p = 0.05), those with a primary education ( p = 0.01), prior history of accidents/disasters ( p = 0.02) and those experiencing damage to their home ( p = 0.02). No significant trends were found when the development of other symptoms between the four time points was assessed. CONCLUSIONS: Findings indicate a reduction in anxiety symptoms between 2 and 12 months post-disaster, with PTSD and depression symptoms remaining fairly constant across time. No trends in symptomology were observed over time. The results highlight the need for continued monitoring of those affected by disasters and the identification of subgroups at risk in the aftermath of natural disasters.

Prevalence and characteristics of epilepsy in the Belgian shepherd variants Groenendael and Tervueren born in Denmark 1995-2004.

BACKGROUND: The Belgian shepherd Groenendael and Tervueren is believed to be at higher risk of developing epilepsy than dogs of the common population. This epidemiological study was designed to estimate the prevalence of epilepsy in the Danish population of Groenendael and Tervueren born between 1995 and 2004. Furthermore, it was the intention to describe the clinical manifestation (seizure types and phenomenology) of epilepsy and to identify risk factors for euthanasia once the dog was diagnosed as having epilepsy. METHODS: All owners of Groenendael and Tervueren dogs born between January 1995 and December 2004 and registered in the Danish Kennel Club (1,248 dogs) were contacted and asked to answer a mailed questionnaire concerning epilepsy. Positive responders were subsequently validated in a follow-up interview conducted by telephone using a standardized questionnaire. Owners were questioned about age at first seizure, seizure frequency, seizure duration, a detailed description of seizure phenomenology, post-ictal signs and if a veterinarian had diagnosed the dog with epilepsy. RESULTS: Prevalence of epilepsy was estimated at 9.5%. Mean age of epilepsy debut was 3.3 years (range 0.5-8.0 years). There was an almost equal number of Groenendael (25) and Tervueren (24). The distribution of females and males was 31 and 18 respectively. Twenty-five per cent experienced focal seizures, 53% experienced focal seizures with secondary generalization and 18% experienced primary generalized seizures. In four percent seizures were unclassifiable. The most commonly reported focal seizure phenomenology included ataxia, crawling, swaying, fearful behavior, salivation, excessive attention seeking and disorientation. In 16% of the cases, epilepsy led to euthanasia. Intact dogs with epilepsy had a significantly increased risk of being euthanized because of epilepsy compared to neutered dogs with epilepsy. In 22% of the cases the owners reported that anxiety/hyperactivity/stress could act as a seizure provoking factor. CONCLUSION: A high prevalence of epilepsy appears to be present in the Danish Groenendael and Tervueren population. The relatively late debut age of epilepsy in this breed contributes greatly to the increased prevalence of epileptic individuals, because dogs developing epilepsy late in life are used for breeding unintended.

PTSD and psychological distress in Icelandic parents of chronically ill children: does social support have an effect on parental distress?

The purpose of the study was to investigate psychological distress and the prevalence of PTSD among Icelandic parents of chronically ill children, and the potential effects of social support on distress, at two points in time. The Impact on Family scale (IFS), the Trauma Symptom Checklist (TSC), the Harvard Trauma Questionnaire (HTQ) and the Crisis Support Scale (CSS) were completed by 105 parents of children with various diseases (69 mothers and 36 fathers). Despite the heterogeneity of the sample in terms of disease type, PTSD was present in 13.2% of the parents and an additional 28.6% had subclinical PTSD. Time since diagnosis, length of hospitalizations and disease-related daily care predicted 40% of the HTQ total score.
