Pharmaceutical industry interactions of psychiatric trainees from 20 European countries.

BACKGROUND: Interactions between the pharmaceutical industry (PI) and psychiatrists have been under scrutiny recently, though there is little empirical evidence on the nature of the relationship and its intensity at psychiatry trainee level. We therefore studied the level of PI interactions and the underlying beliefs and attitudes in a large sample of European psychiatric trainees. METHODS: One thousand four hundred and forty-four psychiatric trainees in 20 European countries were assessed cross-sectionally, with a 62-item questionnaire. RESULTS: The total number of PI interactions in the preceding two months varied between countries, with least interactions in The Netherlands (M (Mean)=0.92, SD=1.44, range=0-12) and most in Portugal (M=19.06, SD=17.44, range=0-100). Trainees were more likely to believe that PI interactions have no impact on their own prescribing behaviour than that of other physicians (M=3.30, SD=1.26 vs. M=2.39, SD=1.06 on a 5-point Likert scale: 1 "completely disagree" to 5 "completely agree"). Assigning an educational role to the pharmaceutical industry was associated with more interactions and higher gift value (IRR (incidence rate ratio)=1.21, 95%CI=1.12-1.30 and OR=1.18, 95%CI=1.02-1.37). CONCLUSIONS: There are frequent interactions between European psychiatric trainees and the PI, with significant variation between countries. We identified several factors affecting this interaction, including attribution of an educational role to the PI. Creating alternative educational opportunities and specific training dedicated to PI interactions may therefore help to reduce the impact of the PI on psychiatric training.

A controlled follow-up study of adolescents exposed to a school shooting--psychological consequences after four months.

BACKGROUND: In November 2007, a student shot eight people and himself at Jokela High School, Finland. This study aims to evaluate the long-term effects of exposure to a school shooting among adolescents. METHOD: Associations between psychological outcomes and background factors were analysed and compared with "comparison students" four months after the incident. A questionnaire including Impact of Event Scale (IES) and General Health Questionnaire (GHQ-36) was used. RESULTS: Half of the females and a third of the males suffered from posttraumatic distress. High level of posttraumatic distress (IES≥35), predicting PTSD, was observed in 27% of the females and 7% of the males. The odds ratio was 6.4 (95% confidence interval 3.5-10.5) for having high levels of posttraumatic distress. Severe or extreme exposure and female gender were found to increase the risk. Forty-two percent of the females and 16% of the males had psychiatric disturbance (GHQ≥9). Severe or extreme exposure, older age and female gender increased the risk. Perceived support from family and friends was found to be protective. CONCLUSIONS: The observed risk and protective factors were similar to earlier studies. Follow-up will be essential in identifying factors predicting persisting trauma-related symptoms in adolescence.

Zaspopathy in a large classic late-onset distal myopathy family.

Distal myopathies have been associated with mutations in titin, dysferlin, GNE, desmin and myosin. Of these, only titin mutations were previously known to cause dominant late-onset distal myopathy. Recent findings, however, have indicated that patients affected with myofibrillar myopathy have a more distal than proximal muscle phenotype and a proportion of these may have mutations in myotilin, ZASP or filamin C, besides previously known desmin and alphaB-crystallin. Here we report that the disorder in one of the well-characterized autosomal dominant distal myopathy families, the Markesbery et al. family, first reported in 1974, is caused by ZASP mutation A165V. Previous linkage to the titin locus 2q31 proved incorrect. ZASP expression by immunoblotting shows normal presence of the main 32 and 78 kDa bands and immunohistochemistry in patients reveals normal Z-disc localization except for moderate accumulations together with myotilin, desmin alphaB-crystallin and alpha-actinin. Muscle imaging reveals involvement in both the posterior and anterior compartments of the lower leg and considerable affection of proximal leg muscles at later stages. Haplotype studies in this family and in five other unrelated families with European ancestry carrying the identical A165V mutation share common markers at the locus suggesting the existence of a founder mutation.

A distinct phenotype of distal myopathy in a large Finnish family.

OBJECTIVES: The authors carried out clinical, histopathologic, immunocytochemical, electrophysiologic, and imaging investigations and molecular genetic analysis in seven patients with distal myopathy belonging to a Finnish family. RESULTS: The disease showed autosomal dominant inheritance. Age at onset ranged from 32 to 45 years. The first symptoms for referral were clumsiness with the hands and frequent stumbling from a steppage gait. Muscle weakness was characterized by early involvement of the small muscles of the hands, gluteus medium, and both anterior and posterior muscle compartments of the legs. The disease progressed to involve other intrinsic muscles of the hands, as well as the forearm muscles, triceps and infraspinatus, and proximal lower limbs. Asymmetry of muscle involvement was common. EMG showed myopathic features, serum CK was normal or slightly elevated, and muscle biopsy showed many rimmed vacuoles and dystrophic changes. There was no evidence of linkage to Welander distal myopathy or tibial muscular dystrophy loci. CONCLUSION: These patients may have a distinct distal myopathy. Genome-wide scan is undertaken in order to identify the disease locus.

Secondary calpain3 deficiency in 2q-linked muscular dystrophy: titin is the candidate gene.

BACKGROUND: Tibial muscular dystrophy (TMD), a late-onset dominant distal myopathy, is caused by yet unknown mutations on chromosome 2q, whereas MD with myositis (MDM) is a muscular dystrophy of the mouse, also progressing with age and linked to mouse chromosome 2. For both disorders, linkage studies have implicated titin as a potential candidate gene. METHODS: The authors analyzed major candidate regions in the titin gene by sequencing and Southern blot hybridization, and performed titin immunohistochemistry on TMD patient material to identify the underlying mutation. Western blot studies were performed on the known titin ligands in muscle samples of both disorders and controls, and analysis of apoptosis was also performed. RESULTS: The authors identified almost complete loss of calpain3, a ligand of titin, in the patient with limb-girdle MD (LGMD) with a homozygous state of TMD haplotype when primary calpain3 gene defect was excluded. Apoptotic myonuclei with altered distribution of transcription factor NF-kB and its inhibitor IkBalpha were encountered in muscle samples of patients with either heterozygous or homozygous TMD haplotype. Similar findings were confirmed in the MDM mouse. CONCLUSIONS: These results imply that titin mutations may be responsible for TMD, and that the pathophysiologic pathway following calpain3 deficiency may overlap with LGMD2A. The loss of calpain3 could be a downstream effect of the deficient TMD gene product. The significance of the secondary calpain3 defect for the pathogenesis of TMD was emphasized by similar calpain3 deficiency in the MDM mouse, which is suggested to be a mouse model for TMD. Homozygous mutation at the 2q locus may thus be capable of producing yet another LGMD.

The first European family with tibial muscular dystrophy outside the Finnish population.

We report the first European tibial muscular dystrophy (TMD) family outside the Finnish population. Clinical examination showed late onset distal leg myopathy similar to the description of TMD. A molecular genetic study was made owing to the very recent TMD linkage findings on chromosome 2q31. All five clinically affected patients segregated a specific haplotype for the locus, whereas two unaffected patients had different haplotype. The results of this family without Finnish ancestors show that TMD exists outside the Finnish population.

Tibial muscular dystrophy--from clinical description to linkage on chromosome 2q31.

A genome scan with highly polymorphic markers has established linkage for tibial muscular dystrophy (TMD), a recently described late onset distal myopathy, to a novel myopathy locus on chromosome 2q31. The mode of inheritance in TMD is autosomal dominant and the typical symptom of ankle dorsiflexion weakness appears in the fourth to seventh decade. Weakness of lower leg muscles is slowly progressive eventually causing a moderate foot drop. Overall disability usually remains mild even in elderly patients and walking ability is preserved throughout the patient's lifetime. The main target of the disease, the tibial anterior muscle, shows progressive dystrophic changes with rimmed vacuoles at the early stages and complete replacement pathology at later stages of the disease. The linkage studies in four different TMD families revealed a common core haplotype with a set of markers on the chromosome 2q31 locus. This indicates one major ancient founder mutation for TMD in Finland. There is one superior candidate gene on the 2q31 locus, the gene encoding a giant protein titin, expressed in heart and skeletal muscle.

Assignment of the tibial muscular dystrophy locus to chromosome 2q31.

Tibial muscular dystrophy (TMD) is a rare autosomal dominant distal myopathy with late adult onset. The phenotype is relatively mild: muscle weakness manifests in the patient's early 40s and remains confined to the tibial anterior muscles. Histopathological changes in muscle are compatible with muscular dystrophy, with the exception that rimmed vacuoles are a rather common finding. We performed a genomewide scan, with 279 highly polymorphic Cooperative Human Linkage Center microsatellite markers, on 11 affected individuals of one Finnish TMD family. The only evidence for linkage emerged from markers in a 43-cM region on chromosome 2q. In further linkage analyses, which included three other Finnish TMD families and which used a denser set of markers, a maximum two-point LOD score of 10.14 (recombination fraction of .05) was obtained with marker D2S364. Multipoint likelihood calculations, combined with the haplotype and recombination analyses, restricted the TMD locus to an approximately 1-cM critical chromosomal region without any evidence of heterogeneity. Since all the affecteds share one core haplotype, the dominance of one ancestor mutation is obvious in the Finnish TMD families. The disease locus that was found represents a novel muscular dystrophy locus, providing evidence for the involvement of one additional gene in the distal myopathy group of muscle disorders.
