PTSD or not PTSD? Comparing the proposed ICD-11 and the DSM-5 PTSD criteria among young survivors of the 2011 Norway attacks and their parents.

BACKGROUND: The conceptualization of post-traumatic stress disorder (PTSD) in the upcoming International Classification of Diseases (ICD)-11 differs in many respects from the diagnostic criteria in the Diagnostic and Statistical Manual for Mental Disorders, fifth edition (DSM-5). The consequences of these differences for individuals and for estimation of prevalence rates are largely unknown. This study investigated the concordance of the two diagnostic systems in two separate samples at two separate waves. METHOD: Young survivors of the 2011 Norway attacks (n = 325) and their parents (n = 451) were interviewed at 4-6 months (wave 1) and 15-18 months (wave 2) after the shooting. PTSD was assessed with the UCLA PTSD Reaction Index for DSM-IV adapted for DSM-5, and a subset was used as diagnostic criteria for ICD-11. RESULTS: In survivors, PTSD prevalence did not differ significantly at any time point, but in parents, the DSM-5 algorithm produced significantly higher prevalence rates than the ICD-11 criteria. The overlap was fair for survivors, but amongst parents a large proportion of individuals met the criteria for only one of the diagnostic systems. No systematic differences were found between ICD-11 and DSM-5 in predictive validity. CONCLUSIONS: The proposed ICD-11 criteria and the DSM-5 criteria performed equally well when identifying individuals in distress. Nevertheless, the overlap between those meeting the PTSD diagnosis for both ICD-11 and DSM-5 was disturbingly low, with the ICD-11 criteria identifying fewer people than the DSM-5. This represents a major challenge in identifying individuals suffering from PTSD worldwide, possibly resulting in overtreatment or unmet needs for trauma-specific treatment, depending on the area of the world in which patients are being diagnosed.

Increased headache prevalence in female adolescents and adult women with early menarche. The Head-HUNT Studies.

BACKGROUND: Age at menarche is associated with cardiovascular events and lifestyle factors such as body mass index (BMI), certain women's diseases like breast cancer and endometriosis and with occurrence of certain physical symptoms during puberty. It is unclear whether age at menarche is an independent determinant of headache. OBJECTIVES: The aim of the study was to explore age of menarche in relation to headache prevalence in a large population-based study of both adolescents and adult women (HUNT). METHODS: In the Nord-Trøndelag Health Study in Norway 1995-97 (HUNT 2), a total of 26,636 (57%) of 46,506 invited women responded to questions regarding menarche and headache (Head-HUNT). In the youth part of HUNT 2, 3196 female students were interviewed about their headache complaints and 2766 (87%) responded to questions regarding menarche. All the final analyses were adjusted for age, use of oral contraceptives and BMI, and for adults also for educational level. RESULTS: Headache was more prevalent amongst females with menarche ≤ 12 years, both amongst adolescents (OR=1.3, 95% CI=1.1-1.5) and adults (OR=1.1, 95% CI=1.1-1.2), evident for migraine and non-migrainous headache. CONCLUSION: Headache, both migraine and non-migrainous headache, was more prevalent amongst both adolescents and adult females with early menarche. Early menarche may increase headache susceptibility, or be a consequence of a common pathogenetic factor, e.g., sensitivity to estrogens.

An unfavorable lifestyle and recurrent headaches among adolescents: the HUNT study.

OBJECTIVES: To examine the relationship between recurrent headache disorders (i.e., migraine and tension-type headache) and lifestyle factors (overweight, low physical activity, and smoking) in an unselected population study among adolescents. METHODS: In this cross-sectional study from Norway, a total of 5,847 students were interviewed about headache complaints and completed a comprehensive questionnaire including items concerning physical activity and smoking. In addition, they underwent a clinical examination with height and weight measurements. Adolescents with high physical activity who were not current smokers and not overweight were classified as having a good lifestyle status. These students were compared to those with 1 or more of the negative lifestyle factors present in regard to headache diagnosis and headache frequency. RESULTS: In adjusted multivariate analyses, recurrent headache was associated with overweight (odds ratio [OR] = 1.4, 95% confidence interval [CI] 1.2-1.6, p < 0.0001), low physical activity (OR = 1.2, 95% CI 1.1-1.4, p = 0.002), and smoking (OR = 1.5, 95% CI 1.3-1.7, p < 0.0001). The prevalence of OR increased with more than 1 negative lifestyle factor present, evident for headache diagnoses and frequency. CONCLUSION: The results from the present study show that overweight, smoking, or low physical activity are independently and in combination associated with recurrent headache among adolescents. The associations observed and the additive effect of these negative lifestyle factors on the prevalence of recurrent headache indicates possible targets for preventive measures.

Traumatic head injury in infants and toddlers.

AIM: To describe the presenting characteristics, type of injury and hospital course in young children with traumatic head injury, and to identify characteristics indicating that the trauma was inflicted. METHODS: A retrospective medical record review of 91 children less than 3 years of age who were admitted to a tertiary teaching hospital in Norway from 1995 through 2005 with a traumatic head injury. Patients were identified by diagnostic codes, and categorized by type of injury as skull fractures (n = 39), epidural haemorrhage (EDH) (n = 12), subdural haemorrhage (n = 27) and parenchymal brain injury (n = 13). Further the cases were classified as inflicted injury (n = 17), accident (n = 35) or indeterminate (n = 39). RESULTS: The mechanism of injury was similar for EDHs and isolated skull fractures, and none were classified as inflicted. Sixty-three percent of the cases with subdural haematoma were classified as inflicted. When compared to the accident group, children in the inflicted group more frequently had subdural haemorrhage without a skull fracture (OR = 6.9, CI = 1.7-28.2), and seizures (OR = 9.5, CI = 2.1-43.3). CONCLUSIONS: Inflicted and accidental head injuries differed in presenting characteristics and injury type. Nearly two-third of the subdural haemorrhages were classified as inflicted, but none of the epidural EDHs or skull fractures. Inflicted injuries tended to present with seizures.

Analgesic overuse among subjects with headache, neck, and low-back pain.

OBJECTIVES: To examine the prevalence of chronic headache (> or =15 days/month) associated with analgesic overuse in relation to age and gender and the association between analgesic overuse and chronic pain (i.e., migraine, nonmigrainous headache, neck and low-back pain). METHODS: In the Nord-Trøndelag Health Study 1995 to 1997 (HUNT-2), a total of 51,383 subjects responded to headache questions (Head-HUNT), of which 51,050 completed questions related to musculoskeletal symptoms and 49,064 questions regarding the use of analgesics. RESULTS: The prevalence of chronic headache associated with analgesic use daily or almost daily for > or =1 month was 1% (1.3% for women and 0.7% for men) and for analgesic overuse duration of > or =3 months 0.9% (1.2% for women and 0.6% for men). Chronic headache was more than seven times more likely among those with analgesic overuse (> or =1 month) than those without (odds ratio [OR] = 7.5, 95% CI: 6.6 to 8.5). Upon analysis of the different chronic pain subgroups separately, the association with analgesic overuse was strongest for chronic migraine (OR = 10.3, 95% CI: 8.1 to 13.0), intermediate for chronic nonmigrainous headache (OR = 6.2, 95% CI: 5.3 to 7.2), and weakest for chronic neck (OR = 2.6, 95% CI: 2.3 to 2.9) and chronic low-back (OR = 3.0, 95% CI: 2.7 to 3.3) pain. The association became stronger with increasing duration of analgesic use for all groups and was most evident among those with headache, especially those with migraine. CONCLUSIONS: Chronic headache associated with analgesic overuse is prevalent and especially chronic migraine is more strongly associated with frequent intake of analgesics than other common pain conditions like chronic neck and chronic low-back pain.

The prevalence of migraine and tension-type headaches among adolescents in Norway. The Nord-Trøndelag Health Study (Head-HUNT-Youth), a large population-based epidemiological study.

The aim of this study was to examine the prevalence of headache and primary headache disorders like migraine and tension-type headaches among adolescents, and to explore the differences in headache prevalence and frequency by gender and age. This cross-sectional study was conducted in Nord-Trøndelag county, Norway, during the years 1995-97. In total, 8984 (88%) out of 10 202 invited adolescents aged 12-19 years participated in the youth part of the Nord-Trøndelag Health Study [Helseundersøkelsen i Nord-Trøndelag (HUNT)]. The total study population in this study consisted of 8255 individuals after exclusion of invalid questionnaires and students outside the target range of 13-18 years of age. The students completed a comprehensive questionnaire, and one of the questions was whether the students had experienced any headaches during the last 12 months. In addition, 5847 of these students were also subject to an interview in which they were asked whether they had experienced recurring headaches during the last year and, if so, were they classified as migraine (MI), tension-type headache (TTH) or non-classifiable headache. In the total questionnaire-based population, 76.8% reported having had headaches during the last 12 months (69.4% boys and 84.2% girls). Among those who also were interviewed, 29.1% reported having recurrent headaches (21.0% boys and 36.5% girls). The overall 1-year prevalence of migraine was 7%, of tension-type headache 18%, and of non-classifiable headache 4.8%. Higher prevalence rates were found for girls in all age groups and for all headache categories. The overall frequency of recurrent headaches did not vary significantly with age, but girls had significantly more frequent headaches than boys. We concluded that headache in general, and recurrent primary headache disorders like migraine and tension-type headaches, are common somatic complaints among Norwegian adolescents, especially among girls.

Analgesic use: a predictor of chronic pain and medication overuse headache: the Head-HUNT Study.

OBJECTIVE: To examine the relation between analgesic use at baseline and the subsequent risk of chronic pain (> or =15 days/month) and the risk of analgesic overuse. METHODS: In total, 32, 067 adults reported the use of analgesics in 1984 to 1986 and at follow-up 11 years later (1995 to 1997). The risk ratios (RR) of chronic pain and RR of analgesic overuse in the different diagnostic groups (i.e., migraine, nonmigrainous headache, neck pain, and low-back pain) were estimated in relation to analgesic consumption at baseline. RESULTS: Individuals who reported use of analgesics daily or weekly at baseline showed significant increased risk for having chronic pain at follow-up. The risk was most evident for chronic migraine (RR = 13.3, 95% CI: 9.3 to 19.1), intermediate for chronic nonmigrainous headaches (RR = 6.2, 95% CI: 5.0 to 7.7), and lowest for chronic neck (RR = 2.4, 95% CI: 2.0 to 2.8) or chronic low-back (RR = 2.3, 95% CI: 2.0 to 2.8) pain. Among subjects with chronic pain associated with analgesic overuse, the RR was 37.6 (95% CI: 21.3 to 66.4) for chronic migraine, 14.4 (95% CI: 10.4 to 19.9) for chronic nonmigrainous headaches, 7.1 for chronic neck pain (95% CI: 5.5 to 9.2), and 6.4 for chronic low-back pain (95% CI: 4.9 to 8.4). The RR for chronic headache (migraine and nonmigrainous headache combined) associated with analgesic overuse was 19.6 (95% CI: 14.8 to 25.9) compared with 3.1 (95% CI: 2.4 to 4.2) for those without overuse. CONCLUSION: Overuse of analgesics strongly predicts chronic pain and chronic pain associated with analgesic overuse 11 years later, especially among those with chronic migraine.

The validity of 'recognition-based' headache diagnoses in adolescents. Data from the Nord-Trøndelag Health Study 1995-97, Head-HUNT-Youth.

The aim of this study was to evaluate the validity of the headache diagnoses (migraine and tension-type headache) obtained from short interviews by nurses, where the subjects were asked to identify their headache(s) based on recognition of typical headache descriptions. All students in junior high schools and high schools aged 12-19 years in Nord-Trøndelag county, Norway, were invited to participate in the youth part of the Nord-Trøndelag Health Study ('Helseundersøkelsen i Nord-Trøndelag'-HUNT), 1995-1997. In this cross-sectional study a total of 8984 students (88%) completed a comprehensive questionnaire with different health-related items. Of these, 6149 were also interviewed by nurses about their headache complaints by giving them two alternative headache descriptions in accordance with either migraine or tension-type headache (Head-HUNT-Youth). The headache diagnoses obtained from nurse interviews were validated in a stratified random sample enriched with headache subjects from the interviewed population. Out of 159 invited individuals, 112 (70%) participated in extensive semistructured interviews by neurologists. The overall chance-corrected agreement (kappa) was 0.76 (confidence interval (CI) 0.66-0.86), which is considered good. For migraine, the positive and negative predictive values were 89% and 90%, respectively, and the chance-corrected agreement (kappa) was 0.72 (CI 0.58-0.87). For tension-type headache, positive and negative predictive values were 83% and 91%, respectively, and chance-corrected agreement (kappa) was 0.74 (CI 0.62-0.87). There was good agreement between the headache diagnoses obtained from the short interviews by nurses and the extensive interviews by neurologists. Short interviews based on recognition of typical headache descriptions seem to be an alternative and efficient way to identify migraine and tension-type headache sufferers among adolescents. The method can be useful in epidemiological research, e.g. in estimation of headache prevalence.

Depression and anxiety disorders associated with headache frequency. The Nord-Trøndelag Health Study.

The aim of this large cross-sectional population-based study was to examine the association between migraine, non-migrainous headache and headache frequency with depression, and anxiety disorders. From 1995 to 1997, all 92 566 inhabitants aged 20 years and above in Nord-Trøndelag County in Norway were invited to participate in the Nord-Trøndelag Health Study ('Helseundersøkelsen i Nord-Trøndelag' = HUNT-2). A total of 64 560 participated, whereof 51 383 subjects (80%) completed a headache questionnaire that was included. Of these 51 383 individuals, 47 257 (92%) completed the depression subscale items and 43 478 (85%), the anxiety subscale items of the Hospital Anxiety and Depression Scale (HADS). Associations were assessed in multivariate analyses, estimating prevalence odds ratios (OR) with 95% confidence intervals (CI). Depression and anxiety disorders as measured by HADS, were significantly associated with migraine (OR = 2.7, 95% CI 2.3-3.2; OR = 3.2, 95% CI 2.8-3.6) and non-migrainous headache (OR = 2.2, 95% CI 2.0-2.5; OR = 2.7, 95% CI 2.4-3.0) when compared with headache-free individuals. The association was stronger for anxiety disorders than for depression. The ORs for depression and anxiety disorders amongst both migraine and non-migrainous sufferers increased with increasing headache frequency. Depression and anxiety disorders are associated with both migraine and non-migrainous headache, and this association seems more dependent on headache frequency than diagnostic category.

[Group work with children and their parents--a support after suspected sexual abuse in a day care center]. / Arbeid i gruppe med barn og foreldre--et hjelpetiltak etter mistanke om seksuelle overgrep i en barnehage.

After alleged sexual abuse in a day care centre, 50 children were referred to the Department of child- and adolescent psychiatry in Trondheim. The children showed symptoms of emotional distress at referral. Group work was offered to the children and their parents. This article describes the group model used to help 36 children and their parents, and the clinical experiences. Group work with children and parents may be a good alternative to individual treatment in similar situations.
