ReviewRewarming from hypothermia. Newer aspects on the pathophysiology of rewarming shock.
The fatal circulatory derangements often observed when resuscitating victims of accidental hypothermia by rewarming are recognized as a falling cardiac output and a sudden drop in blood pressure, termed "rewarming shock". The real cause of this rewarming shock, or rewarming collapse, is, so far, unknown. ⋯ Cellular calcium overload, disturbed calcium homeostasis, changes in myocardial myofilament responsiveness to intracellular calcium as well as impaired high energy phosphate homeostasis could all be proposed as important factors leading to the changes observed in the hypothermic heart. Together with alteration of capillary function, increased capillary leakage of plasma protein, changes in intra- and extravascular volume-homeostasis and alteration of autonomous vascular control they all contribute to a maintained low cardiac output during and after rewarming which is associated with a fatal outcome.

The Harstad injury prevention study: the characteristics and distribution of fractures amongst elders--an eight year study.
To do a complete survey of hospital-treated fractures in the aged (65+ years old) and to report the characteristics and distribution of all fractures occurring within this defined population. ⋯ Nine out of ten fractures in the aged were caused by falls. Although the fracture risk for the elderly living in a nursing home was four times as high as those living in private homes, the volume of fractures occurring in private homes and traffic areas make them a prime target for interventions. Continuous prospective hospital recording of fractures in a community of aged is feasible and provides a tool for targeting interventions and evaluating the outcome of a community fall-fracture prevention programme.

ReviewPrimer on food-borne pathogens for subsistence food handlers.
Subsistence food preparations may lead to human illnesses caused by pathogenic bacteria and viruses. Little is known about the incidence of food-borne illnesses other than botulism in circumpolar indigenous populations. ⋯ This overview covers the major food-borne pathogens, their sources, transmission, growth parameters, and prevention. Examples of indigenous peoples' food preparations that may be susceptible to pathogenic bacterial growth and toxin formation are described.
