Identification of sensory attributes, instrumental and chemical measurements important for consumer acceptability of grilled lamb Longissimus lumborum.

In this study, important eating quality attributes that influence consumer liking for grilled lamb loin have been identified using preference mapping techniques. The eating quality attributes identified as driving the consumer liking of lamb loin steaks were "tenderness", "sweet flavour", "meaty aftertaste", "roast lamb flavour" and "roast lamb aftertaste". In contrast, the texture attribute "rubbery" and the flavour attributes "bitter flavour" and "bitter aftertaste" had a negative influence on consumer perceptions. Associations were observed between eating quality and a number of instrumental and chemical measurements. Warner Bratzler Shear Force showed an association with "rubbery" texture and a negative association with "tenderness" and consumer liking scores. The compounds, glucose, glucose-6-phosphate, inosine, inosine monophosphate and adenosine monophosphate were associated with the attributes, "sweet flavour","meaty aftertaste", "roast lamb flavour", "roast lamb aftertaste" and with consumer scores for liking of lamb which is probably caused by the role some of these compounds play as precursors of flavour and as taste compounds.

Glaucomatous optic neuropathy and field loss in primary empty sella syndrome.

Primary empty sella syndrome is associated with certain visual field defects. Typical glaucomatous field defects, however, have rarely been reported. We reviewed eight cases of primary empty sella syndrome. Seven patients had typical glaucomatous optic disc and visual field changes. Three patients had low-tension glaucoma and four had typical primary open-angle glaucoma. We recommend that in addition to neurologic and endocrinologic assessment, patients with primary empty sella syndrome and visual field loss should have a detailed ophthalmologic examination, particular attention being paid to intraocular pressure and optic disc appearance to rule out glaucoma as a cause of the field loss.

Acanthamoeba keratitis with two species of Acanthamoeba.

We describe a case of Acanthamoeba keratitis related to soft contact lens wear. The patient presented with a 3-week history of severe uniocular pain, radial stromal infiltrates and subepithelial infiltrates with no epithelial defect. Acanthamoeba was cultured from the corneal biopsy specimen, contact lens and lens case. The corneal biopsy culture grew both A. castellani and A. polyphaga as well as Escherichia coli. The patient was treated with topical dibromopropamidine isethionate (Brolene) drops, neomycin and polymyxin B drops and fortified gentamicin drops. Gradual clinical improvement ensued.

Minority ethnic groups in dementia care: a review of service needs, service provision and models of good practice.

Sixty-seven English language articles were obtained for the review, the majority of which (44, 65.7%) had US origins. Broadly, the main issues covered in the literature were the under-utilization of services by minority ethnic groups; the prevalence of dementia in different ethnic groups; the experience of care giving in different racial groups and language as a factor in cognitive assessment. Although it has been argued that the instruments used to assess cognitive function are culturally biased, the available published evidence would seem to suggest that the fundamental issue is language ability, rather than minority group membership per se. Studies into the care giving experience amongst different ethnic or racial groups suffer from theoretical and methodological weaknesses. Studies of help-seeking among various ethnic groups in the US have found that many do not prioritize dementia as a health problem in the face of more pressing concerns. There was little consensus amongst the articles about whether services should be provided specifically for different ethnic groups, reflecting a lack of evidence concerning the efficacy of different models of service provision.

Younger people in dementia care: a review of service needs, service provision and models of good practice.

This paper reviews the literature on younger people (under 65 years of age) with dementia, in dementia care. Seventy-four relevant papers were identified by use of a search strategy derived from the methodology of systematic reviews, the majority of which originated in the UK (69, 93.2%). The need for specialist, flexible, age-appropriate, and dedicated services was a central theme in the literature. A person-centred approach was advocated within an individual or 'tailor made' model of care. However, the available evidence suggests that this model of good practice is not currently reflected in the majority of services provided in the United Kingdom. Overall, the literature argues that the needs of younger people with dementia are best served by inter-agency collaboration, early assessment, and an awareness of individual needs. Clearly, these proposals could usefully serve anybody with dementia, irrespective of age. However, aside from a few prevalence studies, and some exploratory work with small numbers of service users, little in the way of empirical work is available. The recommendations that have been made regarding dementia services for younger people are based largely on the practical experience of professionals and paid carers, rather than scientific evidence.
