Meta AnalysisManagement of drainage for malignant ascites in gynaecological cancer.
Ascites is the accumulation of fluid within the abdominal cavity. Most women with advanced ovarian cancer and some women with advanced endometrial cancer need repeated drainage for ascites. Guidelines to advise those involved in the drainage of ascites are usually produced locally and are generally not evidence-based. Managing drains that improve the efficacy and quality of the procedure is key in making recommendations that could improve the quality of life (QoL) for women at this critical period of their lives. ⋯ Currently, there is insufficient evidence to recommend the most appropriate management of drainage for malignant ascites among women with gynaecological cancer, as there was only very low-certainty evidence from one small RCT at overall high risk of bias.

Epilepsy is a common neurologic disorder, affecting approximately 50 million people worldwide; nearly a third of these people have epilepsy that is not well controlled by a single antiepileptic drug (AED) and they usually require treatment with a combination of two or more AEDs. In recent years, many newer AEDs have been investigated as add-on therapy for focal epilepsy; losigamone is one of these drugs and is the focus of this systematic review. This is an update of a Cochrane Review first published in 2012 and updated in 2018. ⋯ The results of this review showed that losigamone did reduce seizure frequency but was associated with more treatment withdrawals when used as an add-on therapy for people with focal epilepsy. However, the included studies were of short-term duration and uncertain quality. Future well-designed randomized, double-blind, placebo-controlled studies with a longer-term duration are needed. We did not find any new studies since the last version of this review. We judged the overall quality of the evidence for the outcomes assessed as moderate.

Spinal muscular atrophy (SMA) is caused by a homozygous deletion of the survival motor neuron 1 (SMN1) gene on chromosome 5, or a heterozygous deletion in combination with a point mutation in the second SMN1 allele. This results in degeneration of anterior horn cells, which leads to progressive muscle weakness. By definition, children with SMA type I are never able to sit without support and usually die or become ventilator dependent before the age of two years. There have until very recently been no drug treatments to influence the course of SMA. We undertook this updated review to evaluate new evidence on emerging treatments for SMA type I. The review was first published in 2009 and previously updated in 2011. ⋯ Based on the very limited evidence currently available regarding drug treatments for SMA type 1, intrathecal nusinersen probably prolongs ventilation-free and overall survival in infants with SMA type I. It is also probable that a greater proportion of infants treated with nusinersen than with a sham procedure achieve motor milestones and can be classed as responders to treatment on clinical assessments (HINE-2 and CHOP INTEND). The proportion of children experiencing adverse events and serious adverse events on nusinersen is no higher with nusinersen treatment than with a sham procedure, based on evidence of moderate certainty. It is uncertain whether riluzole has any effect in patients with SMA type I, based on the limited available evidence. Future trials could provide more high-certainty, longer-term evidence to confirm this result, or focus on comparing new treatments to nusinersen or evaluate them as an add-on therapy to nusinersen.

Halitosis or bad breath is a symptom in which a noticeably unpleasant breath odour is present due to an underlying oral or systemic disease. 50% to 60% of the world population has experienced this problem which can lead to social stigma and loss of self-confidence. Multiple interventions have been tried to control halitosis ranging from mouthwashes and toothpastes to lasers. This new Cochrane Review incorporates Cochrane Reviews previously published on tongue scraping and mouthrinses for halitosis. ⋯ We found low- to very low-certainty evidence to support the effectiveness of interventions for managing halitosis compared to placebo or control for the OLT and patient-reported outcomes tested. We were unable to draw any conclusions regarding the superiority of any intervention or concentration. Well-planned RCTs need to be conducted by standardising the interventions and concentrations.

Primary delusional infestation (DI) is a primary psychiatric disorder characterised by delusions and abnormal tactile sensations. The pathophysiology is undecided and treatment includes both pharmacological and non-pharmacological options. There is currently no Cochrane Review of the treatments used. Primary DI is a diagnosis often encountered by both dermatologists and psychiatrists, with a large associated disease burden. ⋯ Currently there is no evidence from RCTs available to compare treatment of primary DI with placebo. We cannot, therefore, make any conclusions regarding the effects of treatments (pharmacological or non-pharmacological) for primary DI. This lack of evidence for treatment of primary DI has implications for research and practice. Robust randomised trials are indicated.
