Comparison of two techniques for removing fiber posts.

The purpose of this study was to evaluate the time needed to remove several types of fiber posts using two different bur kits. Estimates refer to the time needed to pass the fiber post until arriving at the gutta-percha. Sixty extracted anterior teeth were treated endodontically. A post space with a standard depth of 10 mm was prepared in each root canal. The sample was randomly divided into 3 groups of 20 specimens each. Three different types of posts were cemented: group 1, Conic 6% tapered fiber posts (Ghimas); group 2, FRC Poster fiber posts (Ivoclar-Vivadent); and group 3, Composipost carbon fiber posts (RTD). To remove the post, for half of each group's specimens the burs from the RTD fiber posts removal kit were used (subgroup A). From the other half of the teeth in each group (subgroup B), posts were removed by using a diamond bur and a Largo bur. Composipost carbon fiber posts (group 3) took significantly less time to remove than the other two types of posts (p < 0.05). For the bur kits, the procedure involving the use of a diamond and a Largo bur (subgroup B) was significantly faster (p < 0.05). The interaction between the type of post and the type of bur kit used was not significant (p > 0.05).

Effects of physical training on straightening-up processes in patients with Parkinson's disease.

PURPOSE: The aim of this study was to evaluate whether motor training could improve the straightening-up sequences in patients with Parkinson's disease and, consequently, could ease the capacity of the patients to change body's position. METHODS: Twenty out-patients with idiopathic Parkinson's disease (12 males, 8 females; mean age 72.9; H-Y, 1. 5-3) were enrolled in a rehabilitation programme which included exercises for the mobility of the trunk, of upper and lower limbs and of each segment of the spine, in order to improve the coordination of movement and to avoid postural disturbances. They received 1 hour of group treatment twice a week for a 5 week consecutive period. No changes were made in the pharmacological treatment received by each patient. The patients were evaluated at the beginning and at the end of the rehabilitation training. The statistical evaluation was made using the Wilcoxon test. RESULTS: Statistically significant differences were observed in all the motor parameters that were evaluated (supine to sitting and sitting to supine, supine rolling, standing from a chair). CONCLUSIONS: The observations demonstrate that physical training can be effective in improving motor performance related to changes in position which affects the simple daily activities of the patients.

Evaluation of Parkinson's disease: a new approach to disability.

Testing the reliability and usefulness of disability scales in Parkinson's disease has been the object of a study carried out by 4 neurologists on 48 patients using 2 rating scales--Hoehn and Yahr staging and Columbia University Rating Scale--and 2 disability scales--Northwestern University Disability Scale and Extensive Disability Scale, a new scale conceived for this purpose, which is more accurate in examining in a different way the physical incapacity and handicap of parkinsonian patients in their daily living. The examiners worked in pairs and did not discuss their rating scores before the end of the study. As far as interobserver agreement is concerned, the results of the disability scales are better than those of the rating scales. The Northwestern Disability Scale and the new scale are similar in reliability and consistency; however, the Extensive Disability Scale has proved to be a better indicator of the functional status. We suggest a more extensive employment of disability scales in clinical studies.

Evaluation of Parkinson's disease: reliability of three rating scales.

We studied the three most commonly used rating scales in Parkinson's Disease (Hoehn and Yahr Clinical Staging, Webster Rating Scale, Columbia University Rating Scale) in order to examine the agreement between observers. Six neurologists, experts at using such scales, evaluated 48 patients suffering from the idiopathic form of Parkinson's Disease. Reliability using the K index was moderate, although a slight superiority was found with the Columbia University Rating Scale. Analysis of the various items used has suggested that scales of disability could be a valid alternative to those examined.

Low dose lisuride in advanced Parkinson disease.

Lisuride was investigated for therapeutic effects in 19 patients with advanced Parkinson disease, no longer satisfactorily responding to routine L-Dopa therapy. The patients were treated with oral Lisuride (0.6-2.5 mg/die) and L-Dopa. The follow-up was at least 6 months. We noted a significant improvement on the Webster Rating Scale at 1st, 3rd and 6th months. Disability and on-off phenomen were reduced. Side effects were few. Lisuride is a valuable tool in this type of patient.
