Large volume plastic spacers in asthma.
describes the setting up of a district wide diabetic register (p 627).6 Disease registers restricted to general practice lists are more limited in their applicability7 in not having a natural population base except where efforts are made to achieve representativeness .8 The subject of a register will usually reflect its intended uses. Registers have thus been classified as preventive (for examp...
متن کاملSafety of inhaled corticosteroids delivered by plastic and metal spacers.
BACKGROUND Because of its non-electrostatic properties the metal Nebuchamber (NC) valved holding chamber (VHC) delivers a greater mass of aerosol to the mouth than the polypropylene Aerochamber (AC) VHC. Delivery of more aerosol to the lungs may also increase systemic absorption of inhaled corticosteroids (ICS) and hypothalamo-pituitary-adrenal (HPA) suppression. METHODS Thirty children (mean...
متن کاملDevelopment of a Plastic Embedding Method for Large-Volume and Fluorescent-Protein-Expressing Tissues
Fluorescent proteins serve as important biomarkers for visualizing both subcellular organelles in living cells and structural and functional details in large-volume tissues or organs. However, current techniques for plastic embedding are limited in their ability to preserve fluorescence while remaining suitable for micro-optical sectioning tomography of large-volume samples. In this study, we q...
متن کاملSpirometry with bronchodilator test: effect that the use of large-volume spacers with antistatic treatment has on test response.
OBJECTIVE To evaluate whether the use of inhaled albuterol via a metered-dose inhaler with a large-volume spacer with antistatic treatment modifies the bronchodilator test results when compared with the usual technique (no spacer). METHODS A prospective study involving 24 patients, 18-45 years of age, clinically suspected of having asthma, and under treatment at the Outpatient Pulmonary Clini...
متن کاملFactors affecting the efficiency of aerosol therapy with pressurised metered-dose inhalers through plastic spacers.
AIM The main objective of this study was to compare the in vitro delivery of salbutamol from a chlorofluorocarbon(CFC)-propelled pressurised metered-dose inhaler (pMDI) versus a newly developed hydrofluoroalkane(HFA)-propelled pMDI through various spacers. In addition, we aimed to study the effect on bronchodilator response when using an optimal pMDI/spacer combination for aerosol delivery comp...
