BackgroundSince people with chromosome 22q11 deletion (CATCH 22 syndrome) have unexpectedly high incidence of major psychosis it has been suggested that 22q area might be involved in the pathogenesis of schizophrenia and bipolar disorders.MethodA single case report.ResultsA 32-year-old male patient with CATCH 22 syndrome and schizophrenia had extensive midline anomalies of the brain in the regions relevant to psychotic disorders.Conclusions22q11-dependent abnormalities in the midline structures of the brain may cause dysfunction in the limbic system and interfere with the interhemispheric information exchange thus predisposing people with CATCH 22 syndrome to psychotic disorders.

The incidence of psychotic disorders is increased, to varying extents, in many migrant and minority ethnic populations in several countries. This chapter briefly reviews the evidence on disparities in incidence between minority and majority populations and then discusses possible explanations. It is unlikely that methodological artifact, including misdiagnosis, can fully account for the high incidence rates observed in some populations. Further, there is no evidence that established neurodevelopmental risk factors for psychosis explain disparities among ethnic groups. It is, then, most likely—and there is growing evidence to support this—that the high rates are a consequence of greater exposure to adverse social conditions and experiences, particularly those involving threat and violence, over the life course among minority ethnic groups. In other words, psychosis occurs more often in some minority populations via a socio-developmental pathway.

IntroductionThere are complex associations between work and mental health. Self-efficacy, experience of own abilities and appropriate challenges are important prerequisites of mental health. Availability of these factors is specifically decreased in the elder long term unemployed and results in higher vulnerability for mental impairment.ObjectivesInvestigation on mental health of elder long term unemployed personsAimsTo examine incidence of mental disorders in elder long term unemployed personsMethodsSenior long term unemployed participants in a vocational reintegration program were examined. Clients were allocated by choice to the study by their placement officers. An extensive psychiatric examination including structured clinical interviews (SKID) and clinical and personality questionnaires (BDI, STAI, MSWS, SCL 90-R, SF36, AUDIT, FTNA) was performed with each subject.Results90 subjects were included into the study so far and 42 completed the psychiatric examination. The mean age was 54.7 years and gender ratio was balanced. 94% were diagnosed with a psychiatric disorder and 80% were diagnosed with more than one disorder according to ICD-10. In particular, 78.6% of the subjects had depression, 40.5% anxiety disorders, 35.7% combined personality disorders, 26.2% posttraumatic disorders, 21.4% addiction disorders, 16.7% single personality disorders and 7.1% psychotic disorders.ConclusionA large proportion of the long term unemployed persons examined is affected by mental disorders. Along with the high incidence of depressive, anxiety and addiction disorders there was a considerable number of personality and specifically trauma-related disorders. Accordingly, personality disorders may be a risk factor for unemployment in elder people too.

The crystalline perfection of bulk CdTe substrates plays an important role in their use in infrared device technology. The application of chemical etchants to determine crystal polarity or the density and distribution of crystallographic defects in (100) CdTe is not well understood. The lack of data on (100) CdTe surfaces is a result of the apparent difficulty in growing (100) CdTe single crystal substrates which is caused by a high incidence of twinning. Many etchants have been reported to predict polarity on one or both (111) CdTe planes but are considered to be unsuitable as defect etchants. An etchant reported recently has been considered to be a true defect etchant for CdTe, MCT and CdZnTe substrates. This etchant has been reported to reveal crystalline defects such as dislocations, grain boundaries and inclusions in (110) and (111) CdTe. In this study the effect of this new etchant on (100) CdTe surfaces is investigated.The single crystals used in this study were (100) CdTe as-cut slices (1mm thickness) from Bridgman-grown ingots.

Purpose This article reviews the psychosocial risks associated with 22q11.2 deletion syndrome, a relatively common genetic condition associated with a range of physical and psychiatric problems. Risks associated with developmental stages from infancy through adolescence and early adulthood are described, including developmental, learning, and intellectual disabilities as well as psychiatric disorders including anxiety, mood, and psychotic disorders. Other risks related to coping with health problems and related treatments are also detailed for both affected individuals and their families. Conclusion The article ends with strategies for addressing psychosocial risks including provision of condition-specific education, enhancement of social support, routine assessment of cognitive abilities, regular mental health screening, and referrals for empirically supported psychiatric and psychological treatments.

Abstract Chapter 14, Mental and Behavioral Disorders, in the AMA Guides to the Evaluation of Permanent Impairment (AMA Guides), Sixth Edition, defines a process for assessing permanent impairment, including providing numeric ratings, for persons with specific mental and behavioral disorders. These mental disorders are limited to mood disorders, anxiety disorders, and psychotic disorders, and this chapter focuses on the evaluation of brain functioning and its effects on behavior in the absence of evident traumatic or disease-related objective central nervous system damage. This article poses and answers questions about the sixth edition. For example, this is the first since the second edition (1984) that provides a numeric impairment rating, and this edition establishes a standard, uniform template to translate human trauma or disease into a percentage of whole person impairment. Persons who conduct independent mental and behavioral evaluation using this chapter should be trained in psychiatry or psychology; other users should be experienced in psychiatric or psychological evaluations and should have expertise in the diagnosis and treatment of mental and behavioral disorders. The critical first step in determining a mental or behavioral impairment rating is to document the existence of a definitive diagnosis based on the current edition of the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders. The article also enumerates the psychiatric disorders that are considered ratable in the sixth edition, addresses use of the sixth edition during independent medical evaluations, and answers additional questions.
