Hyperreactivity of the skin to intracutaneous injection or needle prick (the pathergy test) is a unique feature of Behçet's disease. This phenomenon has been demonstrated to be highly sensitive and even specific in patients with Behçet's disease from Turkey, Japan, and Israel. A lack of positive reaction to this test has been reported in British and(More)
Falls are common in the elderly, and fear of falling is widely prevalent. This review emphasizes some of the defensive adaptations that occur in relation to concern about balance, and the phenomenon of cautious gait and fear of falling. Fear of falling affects those who never fall as well as those who do. Anxiety and fear can profoundly influence motor(More)
The present study investigated the incidence, characteristics, and risk factors predictive of falls in different patient populations hospitalized in a geriatric rehabilitation hospital. Overall 84 fallers and 84 control patients were enrolled in this study. The patients were analyzed into three subgroups: patients hospitalized for stroke rehabilitation, hip(More)
BACKGROUND Knowledge of the prevalence of methicillin-resistant Staphylococcus aureus (MRSA) colonization, and the frequency of transmission is vital for the implementation of MRSA infection control measures in hospitals. We assessed risk factors for and rates of colonization of MRSA upon admission to a geriatric rehabilitation hospital, and studied the(More)
BACKGROUND Risk factors for injurious falls among elderly people differ from those for falls in general. The characteristics of falls play an important role in determining the risk of hip fracture. OBJECTIVE To investigate the risk factors associated with the fall characteristics known to be associated with the majority of hip fractures, e.g., a lateral(More)
OBJECTIVES Smoking causes premature wrinkling and is one of the more potent risk factors for atherosclerosis. The aims of the present study were to verify: (i) whether there is a difference between the wrinkling appearance in aged smokers and the nonsmoking population; and (ii) whether the systemic effects of smoking, such as atherothrombotic disease and(More)
BACKGROUND Dysphagia is a common disorder among the elderly population. As many as 50% of nursing home residents suffer from dysphagia. It is important to identify patients at increased risk for colonization of dental and denture plaque by pathogenic organisms in order to prevent associated disease. OBJECTIVES To quantify the prevalence and evaluate the(More)
BACKGROUND AND DESIGN Decreased sensitization and elicitation of contact allergens in vitiliginous skin has been described. This may be related to altered epidermal Langerhans cell migration with bound hapten to dermis and draining lymph nodes. The aim of the present study was to detect the potential ability of vitiliginous skin to respond to an in vivo(More)
BACKGROUND Alteration of innate and acquired immunity can play a role in the mechanism involved in the development of dementia. Epidemiologic studies indicate that the use of non-steroidal anti-inflammatory drugs can delay the onset or slow progression of Alzheimer disease. OBJECTIVES To determine whether the use of NSAIDs is associated with natural(More)
