[Incidence, circumstances and consequences of falls in patients undergoing rehabilitation after a first stroke].

OBJECTIVES: To describe the incidence, circumstances, and consequences of falls in patients admitted in a rehabilitation ward after a stroke. METHODS: Prospective monitoring of falls over four years in a neurological rehabilitation unit. Use of fall registry. INCLUSION CRITERIA: age < 75 years, admission < 45 days after stroke onset, single stroke of 1 cerebral hemisphere (nonlacunar) or of the brain stem. Only falls due to loss of balance were considered; falls caused by a seizure or syncope were not considered. RESULTS: Of 217 consecutive patients with the inclusion criteria, 34 had fallen at least once (15.7%) and 10 twice (4.1%). Fall incidence, defined as the number of falls per patient per day was 2.2 per thousand. Half of the patients fell the first three weeks after admission. Most falls involved getting to or from the wheelchair or the bed; 1 patient had recovered minimal postural abilities at the gym but was not independent. Traumatic lesions were noted in 13 patients: they were minor in nine and severe in four, including three fractures. CONCLUSION: Falls due to loss of balance are a major problem in patients undergoing rehabilitation after a stroke. Getting to and from wheelchairs in the bedroom and bathroom by patients who are not allowed to do so play a key role in many falls. Prevention programs should consider this information.

Experimental induction of rough dermatitic skin in humans.

The response after application of various concentrations of sodium lauryl sulfate (SLS) on human skin is reported. The induced changes associated variable degrees of roughness and erythema characterizing rough dermatitic skin (RDS). These clinical changes were almost invariably (less than 5% experimental error) associated with increased values of transepidermal water loss (TEWL) and increased cutaneous blood flow values (CBFV). A significant positive correlation was found between TEWL and CBFV at all concentrations of SLS. However, values of TEWL higher than those found in 84% of the controls (mean + SD: 8.127 + 2.89 gr/m2/h) were usually significantly correlated with clearcut clinical changes (total clinical score greater than 2 or erythema greater than 1) at all concentrations of SLS, while CBFV (mean + SD of controls: 2.717 + 2.165) which had a wider dispersion, were significantly associated only with erythema after 10% and 1% SLS. This reflects the distinction that is being made between a primary chemical insult, which we identify clinically as roughness and functionally as increased TEWL associated with alterations of barrier function of the skin, and a secondary, delayed inflammatory response, which is clinically recognized as erythema and functionally objectivated by increased CBFV. These results provide a rational basis supporting the use of this experimental model of RDS for testing of preventive and therapeutic efficacy as well as refining the evaluation of tolerance of cosmetics especially designed for use on sensitive skin.
