- Background Darier disease is an autosomal dominant skin disorder caused by mutations in the ATP2A2 gene. Anecdotal reports suggest a relationship between Darier disease and intellectual disabilities, but these reports are based on small clinical samples and limited by absence of control populations. Objectives To examine the risk of intellectual disability and subclinical impairments in cognitive ability in Darier disease. Methods We conducted a matched cohort study based on Swedish Population-, Patient-and Conscript Registers. The risk of being diagnosed with intellectual disability was estimated in 770 individuals with Darier disease, compared with matched comparison individuals without Darier disease. Associations were examined with risk ratios from conditional logistic regressions. In addition, we analysed test-based cognitive ability data (i.e. IQ data) from the Swedish conscript examination, for a subset of patients without diagnosed intellectual disability. Results Individuals with Darier disease had a sixfold increased risk of being diagnosed with intellectual disability (risk ratio 6.2, 95% confidence interval 3.1-12.4). For conscripted individuals with Darier disease but no diagnosed intellectual disability, mean cognitive ability scores were about half a standard deviation lower than for comparison subjects. Conclusions Darier disease is associated with intellectual disability and subclinical impairments in cognitive ability. The Darier-causing mutations merit further attention in molecular genetic research on intellectual disability and cognitive ability.

- Background: Gender differences in treatment that are not supported by empirical evidence have been reported in several areas of medicine. Here, the aim was to evaluate potential gender differences in the treatment for bipolar disorder. Methods: Data was collected from the Swedish National Quality Assurance Register for bipolar disorder (BipolaR). Baseline registrations from the period 2004-2011 of 7354 patients were analyzed. Multiple logistic regression analysis was used to study the impact of gender on interventions. Results: Women were more often treated with antidepressants, lamotrigine, electroconvulsive therapy, benzodiazepines, and psychotherapy. Men were more often treated with lithium. There were no gender differences in treatment with mood stabilizers as a group, neuroleptics, or valproate. Subgroup analyses revealed that ECT was more common in women only in the bipolar l subgroup. Contrariwise, lamotrigine was more common in women only in the bipolar II subgroup. Limitations: As BipolaR contains data on outpatient treatment of persons with bipolar disorder in Sweden, it is unclear if these Findings translate to inpatient care and to outpatient treatment in other countries. Conclusions: Men and women with bipolar disorder receive different treatments in routine clinical settings in Sweden. Gender differences in level of functioning, bipolar subtype, or severity of bipolar disorder could not explain the higher prevalence of pharmacological treatment, electroconvulsive therapy, and psychotherapy in women. Our results suggest that clinicians' treatment decisions are to some extent unduly influenced by patients' gender. (C) 2014 Elsevier B.V. All rights reserved.

- ObjectiveTo investigate whether persons with bipolar disorder and their siblings have leadership traits and are overrepresented in executive professions. MethodA nested case-control study based on longitudinal Swedish total population registries. Data from officer suitability interviews (n=1126519), and information on occupations were collected. Bipolar patients (n=68915) and their healthy siblings were compared with controls. ResultsBipolar patients without comorbidity (pure; n=22980) were overrepresented in both the highest and lowest strata of officer suitability; their healthy siblings in the highest strata only. Patients with pure bipolar disorder were underrepresented in executive professions, whereas their siblings were overrepresented in these professions (particularly political professions). Patients with general bipolar disorder (including those with comorbidities) and their healthy siblings were overrepresented only in the lowest strata of officer suitability ratings. General bipolar patients were underrepresented in executive professions, whereas their siblings had similar rates of executive professions as controls. Adjusting results for IQ slightly attenuated point estimates, but resulted in pure bipolar patients and their siblings no longer being significantly overrepresented in superior strata of officer suitability, and siblings no longer being overrepresented in executive professions. ConclusionResults support that traits associated with bipolar disorder are linked to superior leadership qualities.
