The correct use of inhaler devices is an inclusion criterion for all studies comparing inhaled treatments. However, in real life patients make many errors when inhaling their medication which may negate the benefits observed in clinical trials. A recently published observational study evaluated inhaler handling in 3811 patients for at least 1 month using the Aerolizer, Autohaler, Diskus, pressurised metered dose inhaler (pMDI) or Turbuhaler devices. ⋯ Ninety per cent of GPs felt that participation in the study would improve error detection. Compliance may be improved by educating patients and physicians in the correct use of inhaler devices. Inhalers should be easy to use correctly, and have multiple feedback and control mechanisms which would reduce physician over-estimation of a correct inhalation, allow compliance to be monitored, facilitate patient self-education and give reassurance to patients in the real life setting.

To review clinical trial evidence supporting treatment of patients to a near-normal HbA(1c) target level and outline therapeutic strategies that optimize glycemic control. ⋯ The results of clinical trials confirm that stringent levels of glycemic control can be attained through the use of intensive multiple-injection insulin regimens (administration of insulin 3 or more times daily by injection or an external pump with dosage adjustments as needed), oral monotherapy or combination therapy, or a combination of insulin and oral therapy. The expanded choices for oral agents and the availability of insulin analogs now provide physicians with the tools to tailor therapy to prevent or delay the devastating complications of diabetes. Indeed, newer insulin analogs, both short-acting (insulin lispro, insulin aspart) and long-acting (insulin glargine), are an important part of a treatment strategy to circumvent diabetes complications and overcome the shortcomings of conventional insulin preparations.

Nursing home-acquired pneumonia (NHAP) is a leading cause of morbidity, hospitalization, and mortality among older nursing home residents. Too often, these patients are erroneously grouped with cases of community-acquired and hospital-acquired pneumonia. Yet, they differ in terms of most common pathogens, significant underlying disease, impaired functional and cognitive status, and poor nutrition. ⋯ This decision often is based on the facility's ability to administer parenteral antibiotics, and care for co-morbidities and complications. Cephalosporins are the foundation of initial treatment of NHAP in the ED, and are combined with other antibiotics in anticipation of the most likely pathogens and treatment variables discussed here. It is hoped the NHAP treatment algorithm will contribute to improved outcomes.

Bisphosphonates (BPs) are widely used in osteoporosis and other bone diseases. Treatment of osteoporosis would, in many instances, involve continued use of BP for a number of years, so it is pertinent to examine skeletal consequences of long-term BP use. Through a non-systematic review of the literature, this commentary considers the reduction in bone turnover and retention in the skeleton with regard to the long-term safety of BP use. ⋯ The amount of BP retained in bone after 10 years of alendronate treatment was estimated at 75 mg per 2 kg mineral, using a pharmacokinetic model for a dose of 10 mg per day. This small fraction, which is unevenly distributed between cancellous and cortical bone, seems unlikely to change bone mechanical properties. Taken together, the known mechanism of action of potent BPs and the experience accrued from treating a large number of patients, including up to 10 years follow-up in controlled trials, have identified only beneficial BP effects on bone.

Bipolar disorder greatly impacts health-related quality of life (HRQoL), physical and social functioning, employment, and work productivity, and greatly increases health-care utilization and costs. Our objective was to characterize how bipolar disorder impacts HRQoL, work impairment, and health-care utilization and costs. ⋯ Bipolar disorder imposes a tremendous burden on patients and the health-care system, resulting in decreased HRQoL and increased medical and work impairment costs. Limited data suggest that appropriate management can improve HRQoL and functioning while reducing utilization and cost.
