The 4- to 6-year outcome of orthograde retreatment was assessed for Phases I and II of the Toronto Study. In total, 523 teeth in 444 patients were retreated. With 395 teeth lost to follow-up and 25 extracted, 103 teeth (34% recall) were examined by two independent, blinded, calibrated examiners for outcome: "healed" (absence of apical periodontitis, signs, or symptoms) or "diseased" (presence of apical periodontitis, signs, or symptoms). The "healed" rate (81%) differed significantly for preoperative apical periodontitis (absent, 97%; present, 78%) and perforation (absent, 89%; present, 42%). Logistic regression revealed an increased risk of disease for preoperative perforation and adequate root filling quality, and postoperative lack of definitive restoration (odds ratios = 26.5, 6.6, and 14.0, respectively). Without perforation, inadequate intraoperative root filling length was also identified (odds ratio = 6.8). This study suggested that apical periodontitis, although a strong predictor, was secondary to preoperative perforation and root filling quality, and to postoperative restoration, in predicting the outcome of retreatment. 相似文献

INTRODUCTION
The study assessed whether there is a greater incidence of divarication of the recti and whether between-recti distance is greater in patients with abdominal aortic aneurysm (AAA).PATIENTS AND METHODS
The study consisted of two parts: a radiological and a clinical assessment. All patients with a confirmed AAA on computerised tomography were included and compared with patients in whom AAA was excluded with imaging. Between-recti distance was measured using a computerised image viewer and clinical divarication was assessed by a surgical registrar or consultant.RESULTS
In the radiological part of the study, 108 patients with AAA were compared with 84 with colorectal cancer. Median between-recti distance was 38 mm (range, 25–59 mm) in the AAA group and 27 mm (range, 20–44.5 mm) in the non-AAA group (P = 0.006). AAA diameter did not correlate with between-recti distance. The clinical study included 50 patients (25 AAA). The groups were well matched, with only a greater incidence of diabetes in the AAA group (20% vs 0%; P = 0.018). AAA patients were more likely to have clinically detected divarication of the recti (76% vs 36%; P = 0.004).CONCLUSIONS
Patients with AAA have greater radiological and clinical evidence of divarication. It is suggested that patients with divarication be screened for AAA. 相似文献44.

Recently, n-3 fatty acids are in the center of attention for their potent anti-inflammatory effects. Osteoporosis as a chronic
senile disease is associated with inflammation, and the role of inflammatory mediators has been demonstrated in recent years.
The beneficial effects of n-3 fatty acids on bone were proven in many animal studies, while to date, no conclusive data is
available in human. The aim of this study was to evaluate the impact of n-3 fatty acids on bone biomarkers in osteoporotic
postmenopausal women. Twenty-five osteoporotic postmenopausal women were recruited in the study and randomized in treatment
and control groups. The patients received 900 mg n-3 fatty acid capsules or placebo per day for 6 months. Serum levels of
osteocalcin, bone alkaline phosphatase (BALP), calcium, vitamin D, and parathormone and urine concentration of pyridinoline
(Pyd) were measured at baseline, second month, and sixth month in both groups. In the treatment group, compared with baseline,
at the second month, osteocalcin increased slightly; thereafter, it showed decrement trend until the end of the study. In
the control group, it decreased all over the study. None of these changes was significant. BALP showed nonsignificant decrease
from baseline over the time in both groups. Urine level of Pyd decreased significantly (P < 0.05) in the treatment group, while no significant change was seen in the control group. Serum calcium and vitamin D increased
in both groups; however, changes were not significant. No significant changes were seen in calcium clearance and parathormone.
In conclusion, n-3 fatty acids can decrease bone resorption; however, it could not affect bone formation significantly after
6 months treatment. Further investigations are recommended. 相似文献

We report a novel missense mutation (Asp109Tyr) in exon 4 of the Cu/Zn superoxide dismutase (sod1) gene in a woman with apparently sporadic amyotrophic lateral sclerosis (SALS). Signs of motor deficit appeared at the age of 51 years which progressed over the next 6 years to upper and lower motor neuron disease and death occurred by the age of 57 years. In this mutation, the base change of guanine to thymine at codon 109 of sod1 gene leads to the replacement of aspartic by tyrosine in the protein. This amino acid change in the protein however, did not alter the catalytic activity of the SOD1 enzyme as there was no change in the enzymatic activity of purified SOD1 from the patient's erythrocytes compared to control. 相似文献
