[Disabilities and handicaps due to hip fractures in the elderly].

OBJECTIVE: to examine mortality, mobility, pain, institutionalization rates six month after hip fractures. DESIGN: observational study, non-selected consecutive patients, time-set protocol. SETTING: urban area (population n = 116,5000), five hospitals. PARTICIPANTS: hip fracture patients (n = 214), age 65 + years (mean 82.4 years). MEASUREMENTS: age, gender, prefracture status, operative procedures, complications, comorbidity, cognition (MMSE), depression (GDS), fear of falling, ADL (Barthel) and mobility and pain status (SAHFE protocol). RESULTS: the incidence for this age group was 636.9/100,000, 31.8% were institutionalized elderly. 84% of the patients were female. Pre-existing comorbidity showed a high prevalence of neurodegenerative (cognitive deficits 53. 6%, Parkinson's disease/syndrome 11.2%) and cerebrovascular diseases (16.8%). Six month postfracture, the mortality was 17.6%. From those surviving 76.2% did walk indoors, 58.5% did also walk outdoors. Independent to dress were 54.6%. Severe pain was reported by 10.2%, whereas 36.9% described no pain. The institutionalization rate at six month was 19.0%. CONCLUSIONS: the study showed considerable mortality, a significant loss in function and social disintegration. Considerable differences were observed for subgroups of patients. Future treatment should focus on risk stratification and include postdischarge training programs. Moreover, preventive strategies should be implemented for high risk groups, such as ambulating patients with a history of stroke. Parkinson's disease and syndrome, dementia and nursing home residents.

Effect of an alum-containing mouthrinse in children for plaque and salivary levels of selected oral microflora.

The purpose of the study was to assess the effect of daily supervised rinsing with a specially formulated, alum-containing mouthrinse on plaque and salivary levels of S. mutans, S. mitis and S. salivarius in caries susceptible children (12-14 years old) and to monitor the effect on the oral tissues and acceptability to subjects. Forty-five subjects were divided into 3 groups (n = 15). Group I received an experimental group with a mouthrinse containing hydrated aluminum potassium sulfate (alum). Group 2 received a vehicle control group containing the same mouthrinse, but without alum and Group 3 had a treatment control with distilled water. All subjects continued normal oral hygiene habits during the study. Salivary and plaque levels were obtained at base line, 2 weeks and 4 weeks and evaluated for microbiologic procedures. Also, potential adverse effects on oral tissues were performed during every visit. The mean plaque and salivary levels of oral Streptococcus (S. mutans, S. mitis, S. salivarius) for the experimental group were significantly reduced after 2 weeks and 4 weeks compared with baseline. The plaque and salivary levels of oral Streptococcus of experimental and vehicle control group differed statistically from each other after 4 weeks, with the strongest reduction in the experimental group and there was statistically difference between treatment control and vehicle control or experimental groups at each time interval. No evidence of deleterious effects to the oral tissues was observed. Daily use of an alum-containing mouthrinse was safe and produced significant reduction effect on plaque and salivary levels of oral Streptococcus and can be used in children for the preventive dentistry.

Flouride release from various restorative materials.

Fluoride release from six light-activated restorative materials, including two resinmodified glass-ionomers, two composites, and two compomers, was evaluated and compared with one conventional acid-based glass-ionomer cement. The amount and rate of release varied among the tested materials. Both resin-modified glass-ionomers and the conventional acid-base glass-ionomer cements released more fluoride then the composites and compomers (p < 0.05). Additionally, composite materials released less fluoride than compomer materials (p < 0.05). Release of fluoride by the tested materials showed a significant decrease after all the tested time intervals.
