ReviewSoy formula for prevention of allergy and food intolerance in infants.
Allergies and food reactions in infants and children are common and may be associated with foods including adapted cow's milk formulas. Soy based formulas have been used to treat infants with allergy or food intolerance. However, it is unclear whether they can be advocated for the prevention of allergy and food intolerance in infants without clinical evidence of allergy or food intolerance. ⋯ Feeding with a soy formula should not be recommended for the prevention of allergy or food intolerance in infants at high risk of allergy or food intolerance.

Review Meta AnalysisPercutaneous transluminal angioplasty and stenting for carotid artery stenosis.
Carotid artery stenosis may be treated endovascularly by percutaneous transluminal balloon angioplasty with or without stent insertion or by primary stenting. Endovascular treatment may be a useful alternative to carotid endarterectomy (CEA), particularly for lesions not suitable for surgery. ⋯ Data from randomised trials comparing endovascular treatment for carotid artery stenosis with carotid endarterectomy suggest that the two treatments have similar early risks of death or stroke and similar long term benefits. However, the substantial heterogeneity renders the overall estimates of effect somewhat unreliable. Furthermore, two trials were stopped early because of safety concerns, so perhaps leading to an over-estimate of the risks of endovascular treatment. On the other hand, endovascular treatment appears to avoid completely the risk of cranial neuropathy. There is also uncertainty about the potential for restenosis to develop and cause recurrent stroke after endovascular treatment. The current evidence does not support a widespread change in clinical practice away from recommending carotid endarterectomy as the treatment of choice for suitable carotid artery stenosis. There is a strong case to continue recruitment in the current randomised trials comparing carotid stenting with endarterectomy.

Review Meta AnalysisSingle dose oral paracetamol (acetaminophen) for postoperative pain.
Paracetamol (acetaminophen) and non-steroidal anti-inflammatory drugs (NSAIDs) are widely used for the relief of mild and moderate pain arising from headache, musculoskeletal conditions and dysmenorrhoea. A prior Cochrane systematic review concluded that paracetamol is also effective for postoperative pain, but additional trials have since been published. This review sought to evaluate the efficacy and safety of paracetamol using current data, and to compare the findings with other analgesics evaluated in the same way. ⋯ Single doses of paracetamol are effective analgesics for acute postoperative pain and give rise to few adverse effects.

Review Meta AnalysisIntravenous immunoglobulin for Guillain-Barré syndrome.
Guillain-Barré syndrome is an acute, paralysing, inflammatory peripheral nerve disease. Intravenous immunoglobulin purified from donated blood is beneficial in other autoimmune diseases. ⋯ Although there are no adequate comparisons with placebo, intravenous immunoglobulin hastens recovery from Guillain-Barré syndrome as much as plasma exchange. Giving intravenous immunoglobulin after plasma exchange is not significantly better than plasma exchange alone. Randomised trials are needed to decide the effect of intravenous immunoglobulin in children, in adults with mild disease and in adults who start treatment after more than two weeks.

Sore throat is a very common reason for people to seek medical care. It is a disease that remits spontaneously, that is, 'cure' is not dependent on treatment. Nonetheless primary care doctors commonly prescribe antibiotics for sore throat and other upper respiratory tract infections. ⋯ Antibiotics confer relative benefits in the treatment of sore throat. However, the absolute benefits are modest. Protecting sore throat sufferers against suppurative and non-suppurative complications in modern Western society can be achieved only by treating with antibiotics many who will derive no benefit. In emerging economies where rates of for example acute rheumatic fever are high, the number needed to treat may be much lower. Antibiotics shorten the duration of symptoms by a mean of one day about half way through the illness (the time of maximal effect), and by about sixteen hours overall.
