Obstructive sleep apnoea is the periodic reduction (hypopnoea) or cessation (apnoea) of airflow during sleep. The syndrome is associated with loud snoring, disrupted sleep and observed apnoeas. Beside conservative treatments there are a range of 8 broad categories of operative treatments for this condition. Surgical treatments aim to relieve the obstruction by either increasing the surface area ⋯ There is an urgent need for high quality randomised controlled trials to be carried out in the field of surgery for obstructive sleep apnoea. More research should also be undertaken to identify and standardise techniques to determine the site of airways obstructions.

Fibrinogen depleting agents reduce fibrinogen in blood plasma, reduce blood viscosity and hence increase blood flow. This may help remove the blood clot blocking the artery and re-establish blood flow to the affected area of the brain after an ischaemic stroke. The risk of haemorrhage may be less than with thrombolytic agents. ⋯ Although ancrod appears to be promising, it is not possible to draw reliable conclusions from the available data.

To estimate the short-term efficacy and toxicity of sulfasalazine for the treatment of rheumatoid arthritis (RA). ⋯ Sulfasalazine appears to have a clinically and statistically significant benefit on the disease activity of patients with RA. Its effects on overall health status and radiological progression are not clear at this time, but would appear to be modest.

ReviewPostoperative caffeine for preventing apnea in preterm infants.
Growing ex-preterm infants who undergo general anesthesia for surgery at about term-equivalent age may have episodes of apnea, cyanosis and bradycardia during the early postoperative period. Caffeine treatment given at the time of operation might prevent these episodes. ⋯ Implications for practice. Caffeine can be used to prevent postoperative apnea/bradycardia and episodes of oxygen desaturation in growing preterm infants if this is deemed clinically necessary. In view of the small numbers of infants studied in these trials and uncertainty concerning the clinical significance of the episodes, caution is warranted in applying these results to routine clinical practice. Implications for research. There is a need to determine which infants might benefit most by this treatment. Studies confined to those most at risk of apnea (prior history, younger postmenstrual age) and those that might require mechanical ventilation (chronic lung disease) would be of value.

ReviewCo-ordinated multidisciplinary approaches for inpatient rehabilitation of older patients with proximal femoral fractures.
Hip fracture is a major cause of morbidity in older people and its impact, both on the individual and to society, is substantial. ⋯ The trials reviewed had different aims, interventions and outcomes. As a consequence, results were heterogeneous and the question of effectiveness of different types of co-ordinated inpatient rehabilitation after hip fracture cannot be answered conclusively. There is a trend to effectiveness when combined outcome variables (death and institutional care, death and deterioration in function) are considered. Future trials of postsurgical care involving inpatient rehabilitation, or other models such as 'early supported discharge' and 'hospital at home' schemes, should aim to establish both effectiveness and cost effectiveness of multidisciplinary rehabilitation overall, rather than attempt to evaluate its components.
