Carvedilol superior to metoprolol for preventing death from CHF
Among white patients with symptomatic systolic dysfunction on stable treatment with diuretics and angiotensin-converting enzyme (ACE) inhibitors, the addition of the nonselective beta-blocker carvedilol extends survival by 17% per year compared with metoprolol. This benefit translates into a number needed to treat (NNT) of 17 for 5 years. This extrapolates to an added 1.4 years of life.
It is unclear whether this benefit holds true for nonwhite patients. Carvedilol should be considered over metoprolol for treating patients with congestive heart failure to improve survival.

Red clover extracts not effective for hot flushes
Both red clover extracts and placebo equally reduce the frequency of hot flushes. Providers should encourage patients to avoid spending money on supplements and instead add soy to their diet. In general, however, if patients are already convinced that something works, don’t discourage them.

Which cytology results predict cervical intraepithelial neoplasia?
For women with cervical cytology results showing atypical squamous cell of undetermined significance (ASCUS) and positive results on DNA testing of a cervical sample for human papillomavirus (HPV) high-risk types, about 1 out of 8 progress to cervical intraepithelial neoplasia (CIN) grades 2 or 3 within 2 years of initial colposcopy results showing not more than CIN 1. Since women with cytology results of lowgrade squamous intraepithelial lesion (LSIL) progress to CIN 2 or 3 in the same proportion, management protocols for HPV-positive ASCUS and LSIL should be identical.

Extended-release oxybutynin and tolterodine treat overactive bladder
Extended-release versions of oxybutynin and tolterodine are similarly effective and tolerable in the treatment of women with overactive bladder. No differences are seen in reduction of weekly episodes of urge incontinence and total incontinence after 3 months of treatment. Extended-release oxybutynin is more effective than extended-release tolterodine in promoting total dryness (no episodes of incontinence) after 12 weeks of treatment. Dry mouth is more common with oxybutynin; however, other side effects are similar.

Local heat decreases renal colic pain
Local heat decreases the pain, anxiety, and nausea of renal colic during emergency transport. Family physicians should offer this to patients as a supplement to routine care of renal colic pain, while watching for other studies that assess its use for different kinds of pain and in settings other than emergency transport.

Educational interventions improve outcomes for children with asthma
Asthma education interventions for children may result in modest improvement in a wide range of clinical outcomes. Interventions should target children with more severe asthma and teach them to use objective measures of lung function, such as peak flow for self-monitoring instead of symptombased self-monitoring.

Oral prednisone prevents relapse in COPD exacerbations
A short course of oral prednisone in the outpatient setting prevents relapse and decreases dyspnea in patients with an exacerbation of chronic obstructive pulmonary disease (COPD). However, physicians should be aware of the potential for weight gain, increased appetite, and insomnia in patients taking this medication.

Negative antigen test misses
For patients with an average risk of having streptococcal pharyngitis, a number of testing strategies can rule out infection, including a single negative rapid strep antigen test, which has a negative predictive value of more than 95%. In patients at higher risk of having strep, based on clinical criteria, all the test strategies being studied are more likely to be falsely negative.
While it is reasonable to rely on a variety of strategies to exclude strep throat in average-risk patients, high-risk patients with a negative rapid antigen test should have an additional rapid strep test or a throat culture to exclude strep with a certainty of greater than 95%.

Thrombolytic therapy for acute ischemic stroke: risks vs benefits
The evidence is not strong enough to recommend routine use of recombinant tissue plasminogen activator (rtPA) in the setting of acute ischemic stroke.
Although independence in activities of daily living 3 to 6 months later is better in those who receive rtPA, acute adverse events (including fatal intracranial hemorrhage) also significantly increase. Given the potentially fatal risks and heterogeneity of results among trials, thrombolytic therapy in the setting of acute ischemic stroke needs more investigation. In the future, we may be able to define a more specific group of patients for whom the potential benefits clearly outweigh the risks.

Estrogen plus progestin may increase incidence of dementia
Estrogen plus progestin does not decrease— and may actually increase—the incidence of dementia, mild cognitive impairment, and cognitive dysfunction in elderly postmenopausal women. The effect of unopposed estrogen on these outcomes is still unknown. With these new findings and the recently reported results of the Women’s Health Initiative, for most women the benefits of estrogen plus progestin do not outweigh the risks.
