Filter by:A study to evaluate the role of forced oscillations in diagnosis of bronchiolitis obliterans syndrome in patients after bone marrow transplantation. The force oscillations technique will be compared with classical spirometry.
Abnormal respiratory sounds (wheezing and/or crackles) are diagnosis criteria of acute bronchiolitis. One third of these infants will develop recurrent episodes, leading to the diagnosis of infant asthma. Nowadays, no available treatment shortens the course of bronchiolitis or hastens the resolution of symptoms, thus, therapy is supportive. Our hypothesis is that the diagnosis of wheezing during bronchiolitis (~60% of infants) will help to select infants who will benefit from anti-asthma therapy. In this setting the diagnosis of wheezing is crucial, and an objective tool for recognition of wheezing is of clinical value. The investigators developed a wheezing recognition algorithm from recorded respiratory sounds with a Smartphone placed near the mouth (Bokov P, Comput Biol Med, 2016). The objectives of the present cross sectional, observational study are 1/ to further validate our approach in a larger sample of infants (1 to 24 months) admitted to hospital for a respiratory complaint during the period of viral bronchiolitis, and 2/ to use gold standard diagnosis of wheezing by respiratory sound recording (Littmann) and subsequent analysis by two experienced pediatricians.
The diagnosis of bronchiolitis, the most frequent lung infectious disease in infancy, is based on clinical examination. Chest X-ray is proposed when a lung parenchymal condensation is suspected. Chest ultrasound is supposed to be a useful tool in the diagnosis of these complication but is poorly evaluated. We aim to compare chest X-ray and chest ultrasound for the diagnosis of parenchymal condensation in infant with bronchiolitis.
A cohort observational study to characterise baseline Structured Light Plethysmography (SLP) outputs in infants with bronchiolitis and examine response to treatment using the Thora3DiTM
Electrical impedance tomography (EIT) is non-invasive and provides functional imaging of the lung and it could be a useful tool to diagnose chronic lung allograft dysfunction (CLAD) and specially Bronchiolitis Obliterans Syndrome (BOS). Hence, for this study, the investigators aim to show that EIT would provide an accurate diagnostic CLAD with an ability to to distinguish BOS from Restrictive Allograft Syndrome (RAS) and to stage BOS accurately when compared to FEV1 the current gold standard. The investigators are also aiming to provide physiological data in lung transplant recipients with chronic rejection.
Epidemics and infectious diseases in general, punctuate much of the activity of an emergency service. The impact of winter infections is particularly important to vulnerable populations such as infant during bronchiolitis epidemics and the elderly during seasonal influenza. Each year, these epidemic phenomena lead to disorganization of emergency services and healthcare teams by lack of anticipation and organizational measures in particular to manage the approval of emergency services for the most vulnerable populations requiring hospitalization. For 2 years, the pediatric emergency department of St Etienne University Hospital has a decision support tool for the periods of winter epidemics. Through a retrospective analysis of Passages of Emergency summary, this tool provides an estimate of infants with bronchiolitis flow day to day, and the availability in real time of an abnormally high flow of patients to pediatric emergencies. These data can help to affirm that the epidemic begins in this hospital.
Over the last decade, high-flow nasal oxygen therapy (HFN) has emerged as a new method to provide respiratory support in children with moderate to severe bronchiolitis. However, any randomized clinical trial (RCT) have demonstrated that earlier support with HFN is superior to standard care including low -flow nasal oxygen therapy to reduce the risk of acute respiratory failure requiring non invasive (or tracheal) ventilation and subsequently the need of PICU transfer.
The purpose of this research is to determine the effect of prolonged slow expiration techniques, provoked coughing and standard therapy compared to chest wall manual vibration and standard therapy in infants between 0 and 12 months old with confirmed diagnosis of acute bronchiolitis SRV (+). The effect will be measured on respiratory insufficiency and use of supplementary oxygen.
The purpose of this study is to determine whether nebulized 3% hypertonic saline is more effective than the current standard of care in the treatment of viral bronchiolitis in children.
The purpose of the study is to evaluate prospectively the clinical benefits of 2 different flow with High flow nasal canula (HFNC: 2l/kg/min) versus (HFNC: 2l/kg/min) in the initial management of bronchiolitis in infants. Design: Prospective, controlled, randomized, multi-center. Design: Infants less than 6 month admitted in pediatric intensive care unit for respiratory distress (mWCAS >3) secondary to bronchiolitis but not requiring mechanical ventilation will be randomized in two groups:HFNC "2l/min/kg" or HFNC "3l/min/kg" during 24 hours. Conditions of measurements: Primary endpoint: Proportion of failure in both arms during the first 24 hours. Failure criteria: A raise of the Clinical score for respiratory distress (mWCAS) (1 point) or respiratory rate (10/min /H0 and above 60/min) or discomfort (EDIN) (1point /H0 and above 4) or apnea. Secondary outcomes: Assessment at H1, H12, H24 of mWCAS, respiratory and heart rate, EDIN score, skin lesions, FiO2 required to achieve an oxygen saturation between 94 and 97%, transcutaneous PCO2 (correlated to an initial gas analysis), Report SpO2 / FiO2 Statistic: Intention to treat Analysis. Expected number of patients: 135 per arm: 270 children.
