A verified spider bite and a review of the literature confirm Indian ornamental tree spiders (Poecilotheria species) as underestimated theraphosids of medical importance.

Literature on bird spider or tarantula bites (Theraphosidae) is rare. This is astonishing as they are coveted pets and interaction with their keepers (feeding, cleaning the terrarium or taking them out to hold) might increase the possibility for bites. Yet, this seems to be a rare event and might be why most theraphosids are considered to be harmless, even though the urticating hairs of many American species can cause disagreeable allergic reactions.

Identifying a cut-off point for normal mobility: a comparison of the timed 'up and go' test in community-dwelling and institutionalised elderly women.

Background: physical mobility testing is an essential component of the geriatric assessment. The timed up and go test measures basic mobility skills including a sequence of functional manoeuvres used in everyday life.

Objectives: to create a practical cut-off value to indicate normal versus below normal timed up and go test performance by comparing test performance of community-dwelling and institutionalised elderly women.
