ReviewNew Pharmacotherapeutic Approaches for Chronic Obstructive Pulmonary Disease.
The last 5 years have seen a proliferation of data about the best way to treat chronic obstructive pulmonary disease (COPD). New long-acting inhaled β-agonist and antimuscarinic drugs have been developed as a once-daily inhaled corticosteroid. ⋯ New data are beginning to define which patients benefit from which treatments and this will help us develop more appropriate treatment regimes. These topics are considered in this review which provides an overview of the latest data and some direction as to how these findings can be applied in practice.

Quantitative sensory testing is widely used in human research to investigate the state of the peripheral and central nervous system contributions in pain processing. It is a valuable tool to help identify central sensitization and may be important in the treatment of low back pain. The aim of this study was to evaluate changes in local and segmental hypersensitivity and endogenous pain inhibition in people with chronic nonspecific low back pain. ⋯ During CPM, people with chronic low back pain have significantly lower PPT than controls in lumbar region [118.6 kPa (mean difference) 95 % CI 77.9-159.2 kPa]. Women had significantly lower PPTs than men in both lumbar region [101.7 kPa (mean difference) 95 % CI 37.9-165.7 kPa] and over the TA [189.7 kPa (mean difference) 95 % CI 14.2-145.2 kPa]. There was no significant difference in PPTs in men between healthy controls and those with low back pain, suggesting the significant differences are mediated primarily by difference between women.

Lymphangioleiomyomatosis (LAM) is a manifestation of tuberous sclerosis complex (TSC) that causes destruction of the lung and chronic respiratory failure. Population-based estimates of demographics, clinical outcomes, and health-care utilization are lacking for TSC and LAM. ⋯ The prevalence of TSC in Quebec, Canada, is similar to estimates from previously published surveys. LAM is likely underreported, perhaps due to suboptimal case identification or referral. Health-care utilization and mortality for LAM are high, suggesting that timely diagnosis and therapy could be beneficial. Mental health disorders may be an unrecognized clinical feature of LAM. These results provide a population-based background for policymakers and researchers to better address the needs of patients with TSC and LAM.

Primary ciliary dyskinesia (PCD) is characterised by chronic suppurative lung disease, rhino-sinusitis, hearing impairment and sub-fertility. We have developed the first multidimensional measure to assess health-related quality of life (HRQoL) in adults with PCD (QOL-PCD). Following a literature review and expert panel meeting, open-ended interviews with patients investigated the impact of PCD on HRQoL in the UK and North America (n=21). ⋯ Cognitive testing confirmed that content was comprehensive and the items were well-understood by respondents. Content validity and cognitive testing supported the items and structure. QOL-PCD has been translated into other languages and is awaiting psychometric testing.

ReviewThe Role of Noninvasive Ventilation in the Hospital and Outpatient Management of Chronic Obstructive Pulmonary Disease.
Positive pressure noninvasive ventilation (NIV) has become widely accepted in the treatment of both hospitalized and outpatient subjects with chronic obstructive pulmonary disease (COPD). The support has evolved over the past two decades to be part of first-line management in acute exacerbations of COPD and is also instrumental in discontinuing mechanical ventilation in COPD patients with acute respiratory failure. It is also suitable for treatment of COPD with other associated conditions including pneumonia, following lung resectional surgery, with concomitant obstructive sleep apnea and as part of end-of-life care. ⋯ However, an approach with higher pressures with a goal of significant reduction in daytime PaCO2 may be an effective strategy. NIV can also facilitate exercise training in pulmonary rehabilitation. A portable device which can augment tidal volume during ambulation and other activities of daily living may further expand the use of NIV in COPD patients.
