ReviewLimited (information only) patient education programs for adults with asthma.
A key component of many asthma management guidelines is the recommendation for patient education and regular medical review. A number of controlled trials have been conducted to measure the effectiveness of asthma education programmes. These programmes improve patient knowledge, but their impact on health outcomes is less well established. At its simplest level, education is limited to the transfer of information about asthma, its causes and its treatment. This review focused on the effects of limited asthma education. ⋯ Use of limited asthma education as it has been practiced does not appear to improve health outcomes in adults with asthma. However the use of information in the emergency department may be effective, but this needs to be confirmed.

ReviewMycobacterium vaccae immunotherapy for treating tuberculosis.
Mycobacterium vaccae has been advocated for immunotherapy in the treatment of tuberculosis and other infections caused by mycobacteria. ⋯ Immunotherapy with Mycobacterium vaccae does not appear to benefit patients with tuberculosis.

Endotracheal tubes are foreign bodies that may injure the upper airway causing laryngeal edema. This in turn may result in failure of extubation in preterm infants. Corticosteroids have been used prophylactically to reduce upper airway obstruction and facilitate extubation. ⋯ Implications for practice Dexamethasone reduces the need for endotracheal reintubation of neonates after a period of IPPV. In view of the lack of effect in low risk infants and the documented and potential side effects, it appears reasonable to restrict its use to infants at increased risk for airway edema and obstruction, such as those who have received repeated or prolonged intubations. Implications for research Issues of dosage and applicability to the extremely low birthweight population could be addressed in future trials. Longer term outcomes such as chronic lung disease, duration of assisted ventilation and length of hospital stay should also be examined.

To determine the effects of allopurinol in the treatment of chronic prostatitis ⋯ One small trial of allopurinol for treating chronic prostatitis showed improvements in patient-reported symptom improvement, investigator-graded prostate pain, and biochemical parameters. However, the data provided, the measures used, and the statistics presented do not make these findings convincing that changes in urine and prostatic secretion composition regarding purine and pyrimidine bases resulted in the relief of symptoms. Further studies of allopurinol treatment using standardized and validated outcomes measures and analyses are necessary to determine whether allopurinol is effective.

Betamimetic drugs may promote fetal growth by increasing the availability of nutrients and by decreasing vascular resistance. They may also induce adverse effects via their effects on carbohydrate metabolism. ⋯ There is not enough evidence to evaluate the use of betamimetics in promoting fetal growth. Larger studies are needed to investigate possible adverse effects of long-term betamimetic administration.
