Knowing which factors influence restoration longevity can help clinicians make sound treatment decisions. The authors analyzed data from The National Dental Practice-Based Research Network to identify predictors of early failures of amalgam and resin-based composite (RBC) restorations.
In this prospective cohort study, the authors gathered information from clinicians and offices participating in the network. Clinicians completed a baseline data collection form at the time of restoration placement and annually thereafter. Data collected included patient factors, practice factors and dentist factors, and the authors analyzed them by using mixed-model logistic regression.
A total of 226 practitioners followed up 6,218 direct restorations in 3,855 patients; 386 restorations failed (6.2 percent) during the mean (standard deviation) follow-up of 23.7 (8.8) months. The number of tooth surfaces restored at baseline helped predict subsequent restoration failure; restorations with four or more restored surfaces were more than four times more likely to fail. Restorative material was not associated significantly with longevity; neither was tooth type. Older patient age was associated highly with failure (P

The study evaluates the prevalence and diagnoses of abdominal complaints in general practice, and compares characteristics and symptoms of patients with functional gastrointestinal disorders (FGIDs) and organic diseases.
A cross-sectional study.
Nine centres with 26 participating general practitioners (GPs) in Norway.
3097 out of 3369 consecutive adult patients answered a questionnaire regarding abdominal complaints IN the last 3 months. Those who consulted for the complaints were eligible for this study.
The GPs' diagnoses and patients' characteristics were reported in questionnaires.
460 out of 1499 patients with abdominal complaints consulted for these complaints; 392 were included in this study. The GPs diagnosed an FGID in 167 (42.6%) patients, organic disease in 145 (37.0%), and made no diagnosis in 80 (20.4%). Stress-related symptoms were a statistically significant predictor of a FGID (OR 1.95) and weight loss predicted in addition organic disease (OR 2.7) in 128 patients with a verified diagnosis.
Abdominal complaints are a common problem in general practice. The distinction between FGID, which accounted for half of the diagnoses, and organic disease was difficult. The only significant predictor for FGID was stress-related symptoms.

It has become clear that nursing is a high-risk occupation with regards to stress-related diseases. In this study, we were interested in nurses' experiences of stress and the emotions arising from stress at work. Results showed that nurses experienced negative stress which was apparently related to the social environment in which they worked. Four nurses were interviewed. The method used was grounded theory. Analysis of the interviews singled out absence of response as the core category. Recurring stressful situations obviously caused problems for the nurses in their daily work. Not only did they lack responses from their supervisors, they also experienced emotions of frustration, powerlessness, hopelessness and inadequacy, which increased the general stress experienced at work. Our conclusion is that the experience of absence of response leads to negative stress in nurses.
To test whether academic centers (ACs) are more successful than nonacademic centers (NACs) in immunohistochemistry (IHC) external quality assessment challenges in the Canadian Immunohistochemistry Quality Control (CIQC) program.
Results of 9 CIQC challenges for breast cancer marker (BM) and various non-breast cancer marker (NBM) tests were examined. Success rates were compared between AC/NAC laboratories and those located in small or large cities. Performance was also correlated with annual IHC case volumes.
There was no statistically significant difference in performance in any of the comparisons. However, overall performance on BM was significantly better (P
The main purpose of the study was to investigate the prevalence of perceived symptoms of musculoskeletal disorders (MSD) among workers on large-scale dairy and pig farms in Sweden (herd size more than 300 cows and 450 sows) and to identify potential risk factors in the development of MSD. A study based on questionnaires was carried out among 42 workers on 10 large dairy farms and among 37 workers on 10 large pig farms in Southern Sweden during the autumn of 2002. Most importantly, the study showed that 86% of the dairy workers and 78% of the pig workers reported some kind of MSD during a period of 12 months prior to the study. The most frequently reported MSD among both the dairy and the pig workers were in the "upper extremities" (52% and 62%, respectively) especially in the shoulders and in "the back" (60% and 57%, respectively) especially in the lower back. Furthermore, being of short stature, doing repetitive work, working in awkward positions and being exposed to dust were significant risk factors in having MSD among the workers in this study. Thus, working with many cows and sows on large-scale farms in Sweden can be considered as a high risk job with regard to MSD.
A total of 3,727 in-patients with acute abdominal symptoms were identified during the first quarter of 1995 at the surgical clinics of the nine hospitals with emergency departments in the county of Stockholm. The diagnoses were: non-specific abdominal pain 24%; cholecystitis 9%; appendicitis 8%; bowel obstruction 7%; intra-abdominal malignancy, diseases of the urinary tract and peptic ulcer 6% each; gastrointestinal hemorrhage, diverticulitis of the colon and pancreatitis 5% each; other diseases as a cause of abdominal symptoms, 19%. 1,601 operations were performed of which 47% were endoscopic procedures. The mean duration of hospital stay was 4.8 days. The length of stay increased significantly with age. The age-related relative frequency of hospitalization due to acute abdominal pain was also dramatically higher in the elderly cohorts. These facts and the prognosis of an 18% increase of inhabitants 50 years of age or older until 2010 in Greater Stockholm signal an increased need of hospital resources for this large group of patients in the coming years.
