Trends in the prevalence of intellectual disability among children in Taiwan.

BACKGROUND: Intellectual disability (ID) is a major developmental disability. However, data on changes in the prevalence over time at the national level are limited. METHOD: Using data from the national disability registry, we conducted an ecological study to evaluate the time trends of ID among children in Taiwan. We calculated the prevalence of ID by age, sex and severity, from 2000 to 2011, and assessed the time trends. RESULTS: During the study period, the overall prevalence of ID in children aged 3-17 years increased from 3.60 to 5.91 per 1000 (ß = 0.22, P < 0.001, r2  = 0.97). The prevalence of mild ID (MID, intelligence quotient: 50-69) increased from 1.30 to 3.60 per 1000 (ß = 0.21, P < 0.001, r2  = 0.98). However, the prevalence of severe ID (SID, intelligence quotient: <50) was relatively constant, between 2.22 and 2.38 per 1000 (ß = 0.01, P = 0.076, r2  = 0.96). Boys had a higher prevalence than girls, and the average boy-to-girl prevalence ratio was 1.42 for MID and 1.31 for SID. The boy-to-girl prevalence ratios of MID and SID decreased over time (ß = -0.01, P < 0.001, r2  = 0.99 for MID; ß = -0.01, P < 0.001, r2  = 1.00 for SID). CONCLUSION: The prevalence of ID in Taiwanese children increased from 2000 to 2011 and was largely attributable to increases in MID. Boys had a higher prevalence of ID and were more likely to have MID.

Cognitive and affective perspectives on formation and maintenance of grandiose delusions of a patient with schizophrenia.

We report on a woman with first-episode schizophrenia with grandiose delusions. She developed a bizarre delusion that she was 'Jesus', who had special powers to talk to animals and predict the future. The grandiose delusions were maintained by her positive emotions, positive imagery of becoming an extraordinary person, and cognitive biases. With the application of cognitive and affective model for formulation of an intervention plan, it was found that the patient had improvement in lowered shamefulness about herself and skills of setting appropriate expectations. The assessment and treatment process of this patient shows the value of applying theory to case formulation and making a care plan for the case management service for patients with first-episode psychosis. This report has clear limitations in that it is a discussion of a single patient, and the case formulation is speculative at this time. The formation and maintenance of grandiose delusions are discussed from the cognitive and affective perspectives.

Developments in early intervention for psychosis in Hong Kong.

The year 2011 marked the 10-year milestone of early intervention for psychosis in Hong Kong. Since 2001, the landscape of early psychosis services has changed markedly in Hong Kong. Substantial progress has been made in the areas of early intervention service implementation, knowledge generation, and public awareness promotion. Favourable outcomes attributable to the early intervention service are supported by solid evidence from local clinical research studies; early intervention service users showed improved functioning, ameliorated symptoms, and decreased hospitalisation and suicide rates. Continued development of early intervention in Hong Kong over the decade includes the introduction and maturation of several key platforms, such as the Hospital Authority Early Assessment Service for Young People with Psychosis programme, the Psychosis Studies and Intervention Unit by the University of Hong Kong, the Hong Kong Early Psychosis Intervention Society, the Jockey Club Early Psychosis Project, and the postgraduate Psychological Medicine (Psychosis Studies) programme. In this paper, we reviewed some of the major milestones in local service development with reference to features of the Hong Kong mental health system. We describe chronologically the implementation and consolidation of public early intervention services as well as recent progresses in public awareness work that are tied in with knowledge generation and transfer, and outline the prospects for early intervention in the next decade and those that follow.

Factors related to outcome of salvage therapy for isolated cervical recurrence of squamous cell carcinoma in the previously treated neck: a multi-institutional study.

OBJECTIVE: The goal was to identify factors associated with the outcome of salvage therapy for patients with isolated cervical recurrences of squamous cell carcinoma in the previously treated neck (ICR-PTN). STUDY DESIGN AND SETTINGS: A tumor registry search for ICR-PTN patients was performed at 7 participating institutions, and the charts were reviewed. Kaplan-Meier plots for survival and time until re-recurrence were used to evaluate the significance of associated variables. RESULTS: Median survival and time until re-recurrence were both 11 months. Survival was better in patients with the following characteristics: nonsurgical initial neck treatment, negative initial disease resection margins, no history of prior recurrence, ipsilateral location of the ICR-PTN relative to the primary, and use of surgical salvage. CONCLUSIONS: By pooling the experience of 7 US tertiary care medical centers, we have identified 5 factors that are associated with outcome of salvage therapy for ICR-PTN. SIGNIFICANCE: Consideration of these factors, as well as the reviewed literature, should facilitate patient selection for salvage protocols.
