Filter by:The study consist of a retrospective analysis of the etiologies, investigations and outcomes of patients presenting between 2005 to 2010 with hemoptysis in a North-American Tertiary center.
Comparison of microbiological yield from Bronchoalveolar Lavage Fluid (BALF) for the two common-used volume bronchoalveolar lavages(60ml and 120ml)in patients with different types of lower respiratory tract infection. Assessment of the safety of two common-used volume bronchoalveolar lavages(60ml and 120ml), including the incidence of hospital-acquired pneumonia within 14 days after bronchoscopy, and other bronchoalveolar lavage related adverse events.
Acute viral respiratory infections are among the most common causes of hospitalization in the pediatric population. The usual presentation of viral respiratory tract infections (VRTI) includes fever, malaise, wheezing and or coughing, rhinorrhea and loss of appetite. Up to 50% of children will have at least one viral-induced wheezing illness by school age. Currently treatment of VRTI is essentially supportive and no specific and efficient treatments are known. Given the lack of effective medications, current treatment for severe viral lower respiratory tract infection (LRTI) in infants relies on supportive measures only. These measures include supplementation of oxygen, monitoring of apnea, nasal/gastric tube feeding or intravenous fluids, and, if required, respiratory support with nasal bi-level positive-airway pressure. VTRI therefore represent an important unmet need for improved treatment strategies. Acupuncture's effect on has also been studied. Acupuncture has been shown to be a safe and effective in various respiratory tract inflammations. A review published in 2011 have found that acupuncture is safe for pediatric patients. Acupuncture's effect on acute viral induced wheezing and cough in hospitalized children has yet to be studied. Since the current standard of care is supportive care only, using acupuncture as an additional treatment may provide benefit in reducing wheezing, respiratory distress, and shorten hospitalization.
It is advocated that prolonged infusion of beta-lactamic antibiotics provides better bactericidal effect. The aim of the present study is to randomize patients a to extended cefepime infusion regimen (lasting four hours) or to a usual infusion regimen (not lasting more than thirty minutes) and evaluate the clinical efficacy of this theoretical pharmacokinetic advantage.
The aim of this study is to compare the efficacy of intralesional bevacizumab, a monoclonal antibody against vascular endothelial growth factor, versus the antiviral drug cidofovir in patients with recurrent respiratory papillomatosis.

Objectives of Study：This study aims to evaluate effectiveness, safety and cost-effectiveness on Jinyebaidu granule in treating patients with acute upper respiratory infection. Study design：multi-center double-blind, double-dummy, randomized, controlled trial
This is a multi-centre, prospective, short period incidence observational study of patients in participating hospitals and intensive care units (ICUs) with SARI. The study period will occur, in both Northern and Southern hemispheric winters. The study period will comprise a 5 to 7-day cohort study in which patients meeting a SARI case-definition, who are newly admitted to the hospitals / ICUs at participating sites, will be included in the study. The study will be conducted in 20 to 40-hospital/ ICU-based research networks globally. All clinical information and sample data will only be recorded if taken as part of the routine clinical practice at each site and only fully anonymised and de-identified data will be submitted centrally. The primary aim of this study is to establishing a research response capability for a future epidemic / pandemic through a global SARI observational study. The secondary aim of this study is to investigate the descriptive epidemiology and microbiology profiles of patients with SARI. The tertiary aim of this study is to assess the Ethics, Administrative, Regulatory and Logistic (EARL) barriers to conducting pandemic research on a global level.
The purpose of this study is to investigate the effectiveness of oral procaterol in treatment of non-asthmatic patients who suffer from persistent cough following upper respiratory tract infection (URTI).
Premature infants (born before 34 wk) are routinely vaccinated against RSV but vaccination rate against influenza are low in spite of national programs. Study goal is to evaluate the effectiveness of short intervention during RSV prophylaxis visit, planned to educate parents about the importance of influenza vaccination.
Poor Ecuadorian older people suffer from chronic dietary deficiencies of zinc, iron, copper, vitamins C, B6, B12, D, and folic acid. The investigators have previously shown that these deficiencies are associated with impaired immune function and increased incidence of respiratory infections (RI). The hypothesis is that correction of these specific nutrient deficiencies will improve immune response and thereby enhance resistance to respiratory infections. To test this hypothesis this study will evaluate the effect of supplementation with specific vitamins and minerals found to be deficient in poor elderly Ecuadorians on markers of immune function and the incidence of RI. A randomized, double-blind, placebo-controlled trial in 320 older people (≥65 y)will be carried out in Quito, Ecuador. Participants will receive multivitamin and mineral supplements or placebo tablets daily for 12 months. Nutrients will be provided at US Recommended Daily Allowance (RDA) levels, except for vitamin C and zinc doses, which will be 5 times and 1.25 times higher than the RDA, respectively. Incidence of respiratory infections (the primary outcome) will be assessed weekly by field nurses and physicians from the study team. Secondary outcomes include delayed-type hypersensitivity (DTH) skin test, cathelicidin production by mucosa respiratory cells, and serum C-reactive protein (CRP) as measures of immune function. Blood micronutrient levels and haemoglobin status will be collected as measures of adherence to the trial regimen. Incidence rate of RI and rate ratio (RR) will be calculated to quantify the effect of the intervention on the incidence of respiratory infection. This will be the first trial of its kind conducted specifically in a population of older people known to have poor micronutrient status. The findings of the study may be important for similar populations in other low- and middle-income countries.
