Our study included 27 polyurethane foam workers exposed to MDI only at low concentrations (ranging from 0.0005 to 0.001 ppm) and 27 clerks from the same factory matched by age. Respiratory function tests were performed on a Monday and Friday of the same week at shift onset, 4 h later and at shift end. The subjects under study were asymptomatic for asthma.(More)
BACKGROUND Occupational allergic respiratory symptoms in coffee workers have been frequently reported, but the ultimate cause of sensitization is still debated, castor bean being considered besides green coffee beans. Atopy and cigarette smoking have been suggested as promoting factors of sensitization for several occupational allergens. OBJECTIVE This(More)
We examined the effects of chest wall strapping (CWS) on the response to inhaled methacholine (MCh) and the effects of deep inspiration (DI). Eight subjects were studied on 1 day with MCh inhaled without CWS (CTRL), 1 day with MCh inhaled during CWS (CWSon/on), and 1 day with MCh inhaled during temporary removal of CWS (CWSoff/on). On the CWSon/on day, MCh(More)
OBJECTIVE Surgical resection is the treatment of choice to cure patients with non-small-cell lung cancer (NSCLC); nevertheless, the assessment of the lower limit of surgical tolerance remains difficult. Ventilatory inefficiency (measured as the ventilation to CO(2) production ratio (V'(E)/V'(CO2) slope) is a survival predictor in pulmonary hypertension (PH)(More)
BACKGROUND Nontoxic goiters can cause extrathoracic upper airway obstruction and, if large, may extend into the thorax, causing intrathoracic airway obstruction. Although patients with goiter often report orthopnea, there are few studies on postural changes in respiratory function in these subjects. PURPOSE The aim of this study was to investigate the(More)
Thirty railway workers executed maximal, or near maximal, stress tests with and without the use of a half mask air-purifying respirator (Spasciani 85 A1 P1) fitted with two combined filters for simultaneous protection from organic vapours and particulate matter. The pressure-flow characteristics of inspiratory and expiratory resistance at airflows in the(More)
Ten subjects with occupational asthma who, were either no longer exposed or had minimal exposure, were controlled every three months after cessation of exposure. All subjects showed airway responsiveness to metacholine, complained of mild symptoms and had minor lung function abnormalities. The subjects underwent inhalation therapy with beclomethasone(More)
SUMMARY This case report focuses on a 71-year old patient affected by unknown dyspnea and erythrocytosis referred by his general practitioner to our center for specialist advice after a hematological examination had excluded polycythemia vera on grounds of negative test for JAK2 V617F/exon 12 mutation. An accurate clinical history and physical examination(More)
Nasal and sinusal complaints are considered common among swimmers. Aim of the present study was to evaluate the nasal and bronchial functions, before and after swimming, and the relationship between nasal resistances and FEV1 in competitive swimmers. A group of 30 competitive swimmers were examined: spirometry and nasal respiratory tests were carried out(More)
