Bronchial challenges with ultrasonic mist, histamine and carbachol: A comparison in 87 asthmatic subjects
No full textThe aim of the present investigation is to compare a physical bronchial challenge with two pharmacological tests based on the inhalation of histamine and carbachol solutions in order to assess the discriminative effectiveness of the procedure in asthmatic patients. Moreover, baseline pulmonary function and severity of symptoms are compared to the responses to each test
Oral deflazacort decreases bronchial reactivity to ultrasonically nebulized water in mild asthmatics.
No full textOral deflazacort, a corticosteroid drug with less adverse effects, is effective in reducing bronchial obstruction and reactivity to inhaled methacholine in mild asthmatics
L'ascoltazione del polmone.
No full textL’ascoltazione dell’apparato respiratorio ha un'elevata resa diagnostica quando viene correttamente eseguita e se i reperti ottenuti sono adeguatamente categorizzati. La percezione e la valutazione dei fenomeni acustici polmonari sono tuttavia soggette ad un'elevata variabilità soggettiva, che si traduce in una ridotta concordanza interpretativa tra osservatori diversi, al punto da far ritenere che praticamente ogni singolo Medico faccia riferimento ad una propria classificazione personale. Attualmente la disponibilità di apparecchiature di registrazione e di analisi dei suoni e l'impiego di supporti informatici e telematici consente, attraverso la visualizzazione e l'analisi oggettiva dei pattern grafici dei suoni polmonari, di superare la variabilità di interpretazione inter- ed interindividuale tipica dell'ascoltazione convenzionale del torace, con utili implicazioni nel campo della diagnostica differenziale, della ricerca e della didattica medica

No full textThe oxygen delivery to the diabetic foot may be investigated with transcutaneous oximetry and by the measurement of venous blood oxygen level drawn from the foot dorsal vein
Autonomic Neuropathy Influences Great Toe Blood Pressure.
No full textautonomic neuropathy influences great toe blood pressure without influencing the oxygen peripheral level
L'interesse del minore fra paradigmi (e stereotipi) sostanziali e profili processuali
No full textThe paper aims to reflect on some of the problematic aspects posed by the recent reform regarding the unitary family trial rite and in particular the relationship between measures to ensure the best interest of child involved in the conflict and trial. The author doubt that the trial, based on an adversarial logic, can really be the ground or pacifying the conflict. After analyzing some critical issues confirmed by
practice, the A. suggests a convinced separation between measures aimed
at individuals and possible procedural repercussions, in the belief that the
possible consequences at the procedural level depower the role of supportive
interventions, risking distorting the institutional function of the social welfare service system
Airway disease: Anatomopathologic patterns and functional correlations
No full textAirways represent a serial and parallel branched system, through which the alveoli are connected with the external air. They participate in the mechanical and immune defense against noxious agents, regional flow regulation to optimize the perfusion/ventilation ratio and provide lung mechanical support. Functional exploration of central airways is based on resistance measurement, flow-volume curve or spirometry, while peripheral airways influence parameters as the upstream resistance, the slope of phase III nitrogen washout and the residual volume. Bronchodypamic tests supply important information on airway reversibility and nonspecific reactivity. Anatomopathologic alterations of obstructive chronic bronchitis, pulmonary emphysema and bronchial asthma account for their specific functional and bronchodynamic alterations. There is a growing interest for bronchiolitis in the clinical, radiologic and functional field. This type of lesion, always present in COPD, asthma and interstitial disease, becomes relevant when isolated or predominant. The most useful anatomofunctional classification separates the 'constrictive' forms, the cause of obstruction and hyperinflation, from 'proliferative' forms where an intraluminal proliferation more or less extended to alveolar air spaces as in BOOP (bronchiolitis obliterans organizing pneumonia) results in restrictive dysfunction. Constrictive bronchiolitis obliterans represents a severe and frequent complication of lung and bone marrow transplantation. Idiopathic BOOP may occur with cough or flue-like symptoms. In other cases, constrictive and proliferative forms may have a toxic (gases or drugs), postinfective or immune etiology (rheumatoid arthritis, LES, etc). Respiratory bronchiolitis or smokers' bronchiolitis, an often asymptomatic lesion, rarely associated to an interstitial lung disease, should be considered separately. The relationships between respiratory bronchiolitis, COPD and initial centriacinar emphysema is still to be elucidated. The diagnostic combination of the more sensitive functional tests with HRCT will allow a better understanding of the natural history of the various forms of bronchiolitis
Respiratory physiology of obstructive sleep apneas.
No full textThe effects of obstructive sleep apnea, in terms of hypoxemia, hypercapnia, and added resistance to breathing, are discussed. The reservoirs of oxygen and carbon dioxide, as well as the relevance of the oxyhemoglobin dissociation curve play an important role in the severity of the recurrent derangements of the blood gas exchanges typical of OSAS
