Bromocriptine-associated ototoxicity

Three patients treated with bromocriptine for chronic hepatic encephalopathy showed audiometric evidence of bilateral sensori-neural hearing-loss. Audiometrically, the hearing improved in all three patients when the bromocriptine dosage was reduced, thus suggesting that this drug may produce a reversible ototoxicity

Use of Medicines by Community Dwelling Elderly in Ontario

OBJECTIVE: Prescription medicine use by the elderly is of growing concern as indicated by a large literature focused on rising costs, patient compliance and the appropriateness of use. However, prescriptions account for only a portion of medicines used by the elderly, who have increasing access to non-prescription medicines and natural health products. The objective of this paper is to describe overall medicine use among the elderly in Ontario. METHODS: Using the National Population Health Survey (1996/97), we describe self-reported use of prescription, non-prescription and alternative medicines among elderly Ontarians aged 65+, and we compare use among four age sub-groups and by gender. Analysis is focused on the prevalence of, and the relative balance of use of different types of medicines. RESULTS: About one quarter of the respondents reported using no prescription or non-prescription medicines in the two days prior to being surveyed; a large majority reported using two or fewer medicines only, and use of non- prescription medicines was reported more often than prescription medicines (56% vs 48%). Use of natural health products by seniors is relatively low, but we observe a trend toward increased use in younger age groups. DISCUSSION: The findings place the consumption of prescription medicines by the elderly into a broader context that reveals that much of medicine use by the elderly involves non-prescribed products. We highlight the need to better understand seniors' decision-making regarding the different types of medicines available, and the financial costs and health risks of the medicine regimes of elderly persons.elderly, medicine-use, prescription medicines, over-the-counter medicines, natural health products, NPHS

The I in Autism:severity and social functioning in Autism is related to self-processing

It is well established that children with autism spectrum disorder (ASD) show impaired understanding of others and deficits within social functioning. However, it is still unknown whether self-processing is related to these impairments and to what extent self impacts social functioning and communication. Using an ownership paradigm, we show that children with ASD and chronological- and verbal-age-matched typically developing (TD) children do show the self-referential effect in memory. In addition, the self-bias was dependent on symptom severity and socio-communicative ability. Children with milder ASD symptoms were more likely to have a high self-bias, consistent with a low attention to others relative to self. In contrast, severe ASD symptoms were associated with reduced self-bias, consistent with an ‘absent-self’ hypothesis. These findings indicate that deficits in self-processing may be related to impairments in social cognition for those on the lower end of the autism spectrum

Monolithically integrated active optical devices

Considerations relevant to the monolithic integration of optical detectors, lasers, and modulators with high speed amplifiers are discussed. Some design considerations for representative subsystems in the GaAs-AlGaAs and GaInAs-InP materials systems are described. Results of a detailed numerical design of an electro-optical birefringent filter for monolithic integration with a laser diode is described, and early experimental results on monolithic integration of broadband MESFET amplifiers with photoconductive detectors are reported
