Review Meta AnalysisThyroid hormone replacement for subclinical hypothyroidism.
Subclinical hypothyroidism is defined as an elevated serum thyroid-stimulating hormone (TSH) level with normal free thyroid hormones values. The prevalence of subclinical hypothyroidism is 4% to 8% in the general population, and up to 15% to 18% in women who are over 60 years of age. There is considerable controversy regarding the morbidity, the clinical significance of subclinical hypothyroidism and if these patients should be treated. ⋯ In current RCTs, levothyroxine replacement therapy for subclinical hypothyroidism did not result in improved survival or decreased cardiovascular morbidity. Data on health-related quality of life and symptoms did not demonstrate significant differences between intervention groups. Some evidence indicates that levothyroxine replacement improves some parameters of lipid profiles and left ventricular function.

Review Meta AnalysisAntipsychotic medications for cocaine dependence.
Cocaine dependence is a public health problem characterized by recidivism and a host of medical and psychosocial complications. Cocaine dependence remains a disorder for which no pharmacological treatment of proven efficacy exists, although considerable advances in the neurobiology of this addiction could guide future medication development ⋯ Although caution is needed when assessing results from a limited number of small clinical trials there is no current evidence, at the present , supporting the clinical use of antipsychotic medications in the treatment of cocaine dependence. Furthermore, most of the included studies did not report useful results on important outcomes such as side effects, use of cocaine during the treatment and craving. Aiming to answer the urgent demand of clinicians, patients, families, and the community as a whole for an adequate treatment for cocaine dependence, larger randomised investigations should be designed investigating relevant outcomes and reporting data to allow comparison of results between studies. Moreover some efforts should be done also to investigate the efficacy of other type medications, like anticonvulsant, currently used in clinical practice.

Review Meta AnalysisBehavioural interventions for primary and secondary dysmenorrhoea.
Dysmenorrhoea refers to the occurrence of painful menstrual cramps of uterine origin and is a common gynaecological condition with considerable morbidity. The behavioural approach assumes that psychological and environmental factors interact with, and influence, physiological processes. Behavioural interventions for dysmenorrhoea may include both physical and cognitive procedures and focus on both physical and psychological coping strategies for dysmenorrhoeic symptoms rather than modification of any underlying organic pathology. ⋯ There is some evidence from five RCTs that behavioural interventions may be effective for dysmenorrhoea however results should be viewed with caution as they varied greatly between trials due to inconsistency in the reporting of data, small trial size, poor methodological quality and age of the trials.

When pregnant women near term lie in the supine position the uterus can compress the inferior vena cava, interfering with venous return to the heart. This can result in hypotension, reduced placental perfusion and decreased fetal oxygenation. ⋯ There is not enough evidence from these trials to evaluate use of lateral tilt during caesarean section.

Review Meta AnalysisSurgical management of pelvic organ prolapse in women.
Pelvic organ prolapse may occur in up to 50% of parous women. A variety of urinary, bowel and sexual symptoms may be associated with prolapse. ⋯ Abdominal sacrocolpopexy is associated with a lower rate of recurrent vault prolapse and dyspareunia than the vaginal sacrospinous colpopexy. These benefits must be balanced against a longer operating time, longer time to return to activities of daily living and increased cost of the abdominal approach. The use of mesh or graft inlays at the time of anterior vaginal wall repair may reduce the risk of recurrent cystocele. Posterior vaginal wall repair may be better than transanal repair in the management of rectoceles in terms of recurrence of prolapse. The addition of a continence procedure to a prolapse repair operation may reduce the incidence of postoperative urinary incontinence but this benefit needs to be balanced against possible differences in costs and adverse effects. Adequately powered randomised controlled clinical trials are urgently needed.
