Airborne particles are small, solid particles projected into the air either by natural forces, or by mechanical or man-made processes, and include fibers and dusts. Their toxicity is usually subsequent to inhalation and can lead to pulmonary dysfunctions and diseases, including cancer. Cytochalasin B blocked micronucleus assay in lymphocytes (L-CBMN) has been shown as a sensitive and reliable technique in assessing genotoxic exposure, An extensive search of the PubMed and Web of Science databases allowed retrieval of 18 articles on occupational or environmental exposure evaluating L-CBMN in subjects exposed to fibers or dusts (asbestos, silica, rockwool, beryllium, tobacco, and wood)...

OBJECTIVE: Pharmacists play a relevant role in the real-life management of asthma because they are a first-line referral for patients. In fact, the role of pharmacies has been underlined and evidenced also in guidelines. Nonetheless, the true effect of pharmacy-based management of asthma has been assessed in only a few studies. We review the available literature on asthma management in a territorial pharmacy setting. DATA SOURCES: The literature was searched for the keywords pharmacy, bronchial asthma, control, and management...

BACKGROUNDS: To date adult-onset asthmatic patients who lack a clear stridor and show prolonged coughs and chest discomfort caused by small-airways dysfunction have increased. We examined the small-airways function of these cases and the effectiveness of slow and deep inhalation of FP/FM-pMDI. METHODS: 62 adult-onset asthmatic patients who had prolonged coughs and chest discomfort with the middle or high dose of ICS/LABA combination agents under well technique (32 of BUD/FM-DPI group and 30 of FP/SM-pMDI group) were included into this study...

The usefulness of the forced oscillation technique (FOT) for predicting the treatment outcomes in untreated asthmatic patients is unknown. We investigated whether FOT could predict an improvement in FEV1 following treatment. FOT, spirometry, and fractional exhaled nitric oxide were performed in 31 outpatients before and after undergoing a minimum of two months combination therapy of inhaled corticosteroids and long-acting β2-agonists. The patients were classified as responders or nonresponders to treatment based on the presence or absence of a 10% improvement in the FEV1...

Making an accurate diagnosis of occupational asthma (OA) is, generally, important. The condition has not only significant health consequences for affected workers, but also substantial socio-economic impacts for workers, their employers and wider society. Missing a diagnosis of OA may lead to continued exposure to a causative agent and progressive worsening of disease; conversely, diagnosing OA when it is not present may lead to inappropriate removal from exposure and unnecessary financial and social consequences...

OBJECTIVES: Mobile technology for childhood asthma can provide real-time data to enhance care. What real-time adherence information clinicians want, how they may use it, and if the data meet their clinical needs has not been fully explored. Our goal was to determine whether pediatric primary care and pulmonary clinicians believe a sensor-based mobile intervention is useful in caring for patients with asthma. METHODS: We recruited participants from 3 urban, primary care and 1 pulmonary practice from July to September 2015 in Hartford, CT...

BACKGROUND: Surgery improves symptoms for the majority of chronic rhinosinusitis (CRS) patients; however, physiological changes in the sinus cavities remain poorly characterized. Direct measurement of changes in airflow, pressure, temperature, humidity, and intranasal spray distribution following surgery is technically challenging. Accordingly, we have used computational fluid dynamic modeling to quantify how these parameters change postoperatively. METHODS: Computed tomography images from a normal control, a patient with CRS preoperatively and postoperatively, and a patient following an endoscopic Lothrop procedure (ELP) were used to create 4 three-dimensional models of the sinus cavities...

INTRODUCTION: Inhaled therapy is the mainstay of asthma treatment due to its local and rapid action. However, its efficiency relies on the teaching of a good inhalation technique by health care providers. We assessed health care providers' knowledge and practical skills in the use of inhalation devices. METHODS: An observational multicenter study was conducted in the pulmonology and paediatric wards in Marseille. The departments' common practices, theoretical knowledge and practical skills were assessed through a questionnaire and a demonstration using a spacer device...

Cooled oxygen inhalation was hypothesized as a novel hypothermia technique in a previous study. In the current study, we aimed to determine the optimal temperature of oxygen for this method. This is a prospective, randomized, controlled, examiner-blinded experimental study conducted with 45 healthy, adult, Wistar Hannover male rats. Rats were randomly divided into five groups; group 1: +4°C intubated group (n = 7), group 2: +4°C nonintubated group (n = 9), group 3: +8°C intubated group (n = 9), group 4: +8°C nonintubated group (n = 9), and group 5: control group (n = 9)...

Liposomes are established drug carriers for inhalation owing to their safety and ability to provide controlled drug release in the lung. These carriers can entrap a wide range of therapeutic molecules for delivery in large volumes to the peripheral airways using medical nebulizers. Pressurized metered inhalers (pMDIs), soft mist inhalers (SMIs) and dry powder inhalers (DPIs) can deliver relatively small quantities of medication to the lung when compared to medical nebulizers which can deliver large volumes using simple liposome preparation techniques...

Volatile anesthetics alter the physical properties of inhaled gases, such as density and viscosity. We hypothesized that the use of these agents during mechanical ventilation would yield systematic biases in estimates of flow ([Formula: see text]) and tidal volume (V T) for two commonly used flowmeters: the pneumotachograph (PNT), which measures a differential pressure across a calibrated resistive element, and the hot-wire anemometer (HWA), which operates based on convective heat transfer from a current-carrying wire to a flowing gas...

Pulmonary drug delivery is becoming a favored route for administering drugs to treat both lung and systemic diseases. Examples of lung diseases include asthma, cystic fibrosis and chronic obstructive pulmonary disease (COPD) as well as respiratory distress syndrome (ARDS) and pulmonary fibrosis. Special respiratory drugs are administered to the lungs, using an appropriate inhaler device. Next to the pressurized metered-dose inhaler (pMDI), the dry powder inhaler (DPI) is a frequently used device because of the good drug stability and a minimal need for patient coordination...

BACKGROUND: Asthma is a common problem in children and, if inadequately controlled, may seriously diminish their quality of life. Inhaled short-acting beta2 agonists such as salbutamol are usually prescribed as 'reliever' medication to help control day-to-day symptoms such as wheeze. As with many medications currently prescribed for younger children (defined as those aged 2 years 6 months to 6 years 11 months), there has been no pre-licensing age-specific pharmacological testing; consequently, the doses currently prescribed (200-1000 μg) may be ineffective or likely to induce unnecessary side effects...

BACKGROUND: Little work has been done on identifying the impact of educational materials developed by immigrant patients themselves, along with their caregivers and health professionals in terms of inhaler use technique. The purpose of this study was to evaluate understanding of physicians' instructions on asthma management and inhaler techniques in Punjabi and Chinese subjects using educational interventions in their native languages. METHODS: Eighty-seven subjects with asthma were randomly assigned to either one of 3 experimental groups (physician-led video, subject-generated community video, or both) or a control group (educational pamphlet)...

Chronic inhalation of silica in various occupational settings results in the development of silicosis, a disease characterized by lung fibrosis. Uptake of silica particles by alveolar macrophages results in cell death and this is one of the contributing factors to the development of silicosis. We have characterized the uncoated or protein-coated (non-opsonized) and Fc receptor-mediated (antibody-opsonized) routes of silica phagocytosis and toxicity. Numerous microscopy techniques and fluorescent probes are outlined in this chapter to carefully measure particle uptake, by macrophages, phagosome maturation, phagosomal reactive oxygen species generation, phagolysosomal leakage, and cell death...
