[Determining risk factors associated with falling among elderly at residential care facilities in Tehran]

Falling is a serious and common problem among old people .Falls may lead to pain, slight or sever injuries, increased duration of hospital stay, and discomfort in patients, thus affecting the quality of life. The purpose of this study was to assess the risk factors associated with falling among elderly at residential care facilities and also to determine the gait and balance statuses of old people living in such institutions. This was a descriptive analytical study in which one hundred adults aged 65 or higher with the ability to walk were investigated in 2005. Demographic variables, cognitive and functional status, previous and current medical history, and drug intake were investigated. Balance and gait statuses were evaluated by Tinetti Performance Oriented Mobility Assessment Tool [POMA]. The results showed that the total score for gait and balance tests on POMA were 19-24 among 31% of cases [high risk] and 25-28 in 37% of cases [low risk] whereas 32% of cases were not at risk of falling. The data demonstrated a statistically significant correlation between age and the scores obtained for balance and gait tests and also the sum of scores for both tests [p=0/002, p=0/303]. Furthermore, significant correlations were found between the current physical and psychological diseases, pervious physical diseases, and use of aid devices with the scores obtained for balance and gait tests and also the sum of scores for both tests [p =0]. Considering our data, it is obvious that the elderly who live in institutions are at risk of falling, hence, the application of standard assessment tool used in our study could be suggested as an easy and rapid technique in identifying the risk factors associated with falling at elderly residential care facilities through a targeted multiple intervention

hematological changes in severe burn patients hospitalizing in Tehran burn centers

The hematological changes in burn patients can at times manifest as severe complications. Investigating the hematological changes in hospitalized severe burn patients. In this descriptive study, 120 patients with severe burn were chosen by convenience sampling from 3 burn centers: Towhid, Shahid Motahary and 15[th] Khordad hospitals during the period of 2002 - 2003. The cases were surveyed during first, third and seventh days following burn injury. A single specialist evaluated the complete blood count [CBC] profiles at 3 time intervals. WBC was increased on the first post-burn day; however, it was decreased on the 3[rd] and 7[th] post-burn days, although within normal limits. RBC, hemoglobin and hematocrit were gradually reduced during the mentioned time intervals. Platelet counts were changed drastically, as on the 3rd post-burn day; the presence of thrombocytopenia was evident while on the 7[th] day the count was increased. The correlation between WBC and band cells on the first and 7[th] post-burn days were significant [P=0.001], while it was insignificant on the 3[rd] day [P>0.001]. Since following the severe burns the occurrence of a noticeable change in platelet counts was considerable, the evaluation of MPV for differential diagnosis of thrombocytopenia is recommended
