Review Meta AnalysisShort term benefits for laparoscopic colorectal resection.
Colorectal resections are common surgical procedures all over the world. Laparoscopic colorectal surgery is technically feasible in a considerable amount of patients under elective conditions. Several short-term benefits of the laparoscopic approach to colorectal resection (less pain, less morbidity, improved reconvalescence and better quality of life) have been proposed. ⋯ Under traditional perioperative treatment, laparoscopic colonic resections show clinically relevant advantages in selected patients. If the long-term oncological results of laparoscopic and conventional resection of colonic carcinoma show equivalent results, the laparoscopic approach should be preferred in patients suitable for this approach to colectomy.

Sertindole is an atypical antipsychotic, which is thought to give a lower incidence of extrapyramidal side effects at clinically effective doses than typical antipsychotic drugs. In December 1998, Lundbeck Ltd., the manufacturers of sertindole, voluntarily suspended the availability of the drug due to concerns about cardiac arrhythmia and sudden cardiac death associated with its use. However, based on the advice of an appointed expert group, the Committee for Proprietary Medicinal Products (CPMP) lifted the suspension of sertindole in October 2001, a decision that was ratified by the European Commission on the 26th of June 2002. Lundbeck have committed to the CPMP to carry out two post-marketing surveillance (PMS) studies (which were initiated in July 2002) to provide additional epidemiological data under conditions of normal drug usage. Initial marketing of the product will be restricted and Lundbeck is currently in discussions with the US health authorities (FDA) to investigate whether, and if so when, it would be possible to launch Serdolect in the US market. ⋯ Sertindole at a dose of 20mg/day was found to be more antipsychotic than placebo. When used at 8, 12 or 20mg/day it appears to be as acceptable as placebo (in terms of various adverse events including movement disorders and somnolence), but seems to be associated with more cardiac problems (8, 12 or 20mg/day) and an increase in weight gain (20mg/day) than placebo. Sertindole at a dose of 24mg/day was better tolerated than haloperidol (in terms of participants leaving the study early). It was also found to be was associated with fewer movement disorders (at 8, 16, 20 or 24mg/day) and sedation (8 or 24mg/day) than haloperidol. However, it was shown to cause more cardiac anomalies (16, 20 or 24mg/day), weight gain (all doses combined), rhinitis (16 or 24mg/day), and problems with sexual functioning (24mg/day) than haloperidol. One short term study reported that sertindole 16mg/day was the most optimal dose.

Review Meta AnalysisHigh dose chemotherapy and autologous bone marrow or stem cell transplantation versus conventional chemotherapy for women with metastatic breast cancer.
There is a hypothesis that high dose chemotherapy with autologous bone marrow or peripheral stem cell transplantation (autograft) may improve survival for women with metastatic breast cancer. ⋯ Although there is statistically significant evidence that high dose chemotherapy and autograft improves event free survival compared to conventional chemotherapy, there is no statistically significant evidence of benefit in overall survival for women with metastatic breast cancer. High dose chemotherapy with bone marrow or stem cell transplantation should not be given to women with metastatic breast cancer outside of clinical trials.

Review Meta AnalysisMultiple versus single lumen umbilical venous catheters for newborn infants.
Multiple lumen umbilical venous catheters (ML-UVCs) instead of single lumen UVCs (SL-UVCs) may decrease the need for additional venous lines. Although it seems self-evident that ML-UVCs would reduce the need of additional venous lines, the rates of associated complications might be different. ⋯ The use of ML-UVCs in comparison to SL-UVCs in neonates is associated with decrease in the usage of PIVs in first week of life, but an increase in catheter malfunctions. As the quality of included randomized studies is poor and the estimates of clinically important complications are imprecise, no firm recommendations can be made regarding the choice of UVC. Adequately powered, properly randomized and properly blinded controlled trials are needed that address the effectiveness and safety of ML-UVCs (double and triple lumen) in comparison to SL-UVCs. These studies should also address the impact of type of catheter material.

Review Meta AnalysisCombination injectable contraceptives for contraception.
Combination injectable contraceptives provide a highly effective, reversible method of preventing pregnancy, and they do not require daily administration or use at the time of coitus. Although they are used in many countries, their acceptability could be limited by method characteristics, such as the need to obtain a monthly injection or bleeding pattern changes. ⋯ While discontinuation rates can be viewed as a measure of method acceptability, the findings should be interpreted with caution since discontinuation rates are dependent on many other factors. Future research should be directed toward interventions to improve the acceptability of combination injectable contraceptives, such as providing injections in settings more convenient than clinical sites, methods for women to administer their own injections, and counseling about possible bleeding pattern changes.
