Review Meta AnalysisAntibiotics for preventing complications in children with measles.
Measles is the leading killer among vaccine-preventable diseases; it is responsible for an estimated 44% of the 1.7 million vaccine-preventable deaths among children annually. ⋯ The studies reviewed were of poor quality and used older antibiotics. This review suggests a beneficial effect of antibiotics in preventing complications such as pneumonia, purulent otitis media and tonsillitis in children with measles. On the basis of this review, it is not possible to recommend definitive guidelines on the type of antibiotic, duration or the day of initiation. There is a need for more evidence from high-quality RCTs to answer these questions.

Review Meta AnalysisPostnatal phenobarbital for the prevention of intraventricular haemorrhage in preterm infants.
Intraventricular haemorrhage (IVH) is a major complication of preterm birth. Large haemorrhages are associated with a high risk of disability and hydrocephalus. Instability of blood pressure and cerebral blood flow are postulated as causative factors. Another mechanism may involve reperfusion damage from oxygen free radicals. Phenobarbital has been suggested as a safe treatment that stabilises blood pressure and may protect against free radicals. ⋯ Postnatal administration of phenobarbital cannot be recommended as prophylaxis to prevent IVH in preterm infants and is associated with an increased need for mechanical ventilation.

Review Meta AnalysisAntimicrobial therapy for chronic bacterial prostatitis.
Chronic bacterial prostatitis (CBP) is frequently diagnosed in men of fertile age, and is characterized by a disabling array of symptoms, including pain in the pelvic area (for example, perineum, testicles), voiding symptoms (increased frequency and urgency, also at night; pain or discomfort at micturition), and sexual dysfunction. Cure of CBP can be attempted by long-term therapy with antibacterial agents, but relapses are frequent. Few antibacterial agents are able to distribute to the prostatic tissue and achieve sufficient concentrations at the site of infection. These agents include fluoroquinolones, macrolides, tetracyclines and trimethoprim. After the introduction of fluoroquinolones into clinical practice, a number of studies have been performed to optimize the antimicrobial treatment of CBP, and to improve eradication rates and symptom relief. ⋯ The microbiological and clinical efficacy, as well as the adverse effect profile, of different oral fluoroquinolones are comparable. No conclusions can be drawn regarding the optimal treatment duration of fluoroquinolones in the treatment of CBP caused by traditional pathogens.Alternative antimicrobial agents tested for the treatment of CBP caused by traditional pathogens are co-trimoxazole, beta-lactams and tetracyclines, but no conclusive evidence can be drawn regarding the role of non-fluoroquinolone antibiotics in the treatment of CBP caused by traditional pathogens.In patients with CBP caused by obligate intracellular pathogens, macrolides showed higher microbiological and clinical cure rates compared to fluoroquinolones.

Review Meta Analysis'Mediterranean' dietary pattern for the primary prevention of cardiovascular disease.
The Seven Countries study in the 1960s showed that populations in the Mediterranean region experienced lower cardiovascular disease (CVD) mortality probably as a result of different dietary patterns. Later observational studies have confirmed the benefits of adherence to a Mediterranean dietary pattern on CVD risk factors. Clinical trial evidence is limited, and is mostly in secondary prevention. ⋯ The limited evidence to date suggests some favourable effects on cardiovascular risk factors. More comprehensive interventions describing themselves as the Mediterranean diet may produce more beneficial effects on lipid levels than those interventions with fewer dietary components. More trials are needed to examine the impact of heterogeneity of both participants and the intervention on outcomes.

Percutaneous balloon angioplasty is an endovascular technique for restoring blood flow through an artery that has become narrowed or blocked by atherosclerosis. Narrowing of the artery following angioplasty (restenosis) is the major cause of long-term failure. Cryoplasty offers a different approach to improving long-term angioplasty results. It combines the dilation force of balloon angioplasty with cooling of the vessel wall. This systematic review evaluated cryoplasty in peripheral arterial disease and provides focus for further research in the field. This is an update of a review first published in 2007. ⋯ The benefit of cryoplasty over conventional angioplasty cannot be established as the number of randomised controlled trials is small and their quality is not sufficiently high. The technical success and primary patency rates seen in these trials are inconsistent and do not necessarily suggest a future role for cryoplasty in the treatment of PAD, but they cannot be reliably interpreted. Currently there are insufficient data to support the routine use of cryoplasty over conventional balloon angioplasty in the treatment of PAD.
