Meta Analysis Comparative Study
Breast-conserving therapy vs mastectomy in early-stage breast cancer: a meta-analysis of 10-year survival.
The randomized trials comparing breast-conserving therapy (BCT), i.e., surgery and radiation to the breast, with mastectomy in early-stage breast cancer use a variety of protocols. Meta-analysis may assist in understanding the impact of these differences on survival. ⋯ Patients allocated to BCT have survival rates at least as high as patients allocated to mastectomy. When all protocols were combined, nodal status and tumor size did not significantly alter the relative survival rates. However, under some conditions, particularly for node-positive patients, BCT may confer a relative survival advantage over mastectomy. In particular, mastectomy without adjuvant radiation appears to be inferior to BCT for node-positive patients.

Meta AnalysisPrehospital care, importance of early intervention on outcome.
The improvement of rescue systems and on-scene therapy has lead to a significant reduction of early posttraumatic death. It was the goal of this study to critically analyse the value of prehospital care in respect to early but also to delayed complications (single = SOF or multiple organ failure = MOF) In a retrospective analysis 1223 polytraumatized patients treated during 1984 and 1994, with an injury severity of more than 20 points according to the Injury Severity Score = ISS, on-scene therapy ("field stabilization") was evaluated. We could show that a sufficient preclinical airway management has major influence on late prognosis (MOF). ⋯ Thus for severe blunt trauma the question is still open: "field stabilization" or "load and go" (Krausz 1992). A decision that always has to be related to the definite rescue time (Smith 1985). It was the goal of this study to critically analyse the value of prehospital care in respect to early but also to delayed complications (single = SOF or multiple organ failure = MOF).

To evaluate whether laxatives and fiber therapies improve symptoms and bowel movement frequency in adults with chronic constipation. ⋯ Both fiber and laxatives modestly improved bowel movement frequency in adults with chronic constipation. There was inadequate evidence to establish whether fiber was superior to laxatives or one laxative class was superior to another.

Meta Analysis Comparative StudyThe efficacy of nonopioid analgesics for postoperative dental pain: a meta-analysis.
The evidence for the efficacy of nonopioid analgesics in the dental pain model was examined by conducting a meta-analysis. Studies were obtained by searching the literature from August 1996 back to 1975 using the terms pain, analgesics, and dentistry. This led to the review of 294 articles, of which 33 studies met the inclusion criteria. ⋯ Collectively, therapeutic doses of the nonsteroidal anti-inflammatory drugs (NSAIDs) commonly used in dentistry were significantly more efficacious than the combination of acetaminophen (600 or 650 mg) with codeine (60 mg). Similarly, specific doses of each of diflunisal, flurbiprofen, ibuprofen, and ketorolac were significantly more efficacious than the commonly used acetaminophen-codeine combination. These quantitative results show that particular NSAIDs may be more efficacious than the acetaminophen-codeine combination for relief of postoperative dental pain.
