Filter by:Acute upper respiratory tract infections are the most commmon infections in children and are associated with complications such as acute otitis media, sinusitis and pneumonia. Echinacea is widely used for treatment of upper respiratoty tract infections. The aim of this study is to evaluate its efficacy as prophilaxis in children 1-5 years old.
Validation of Vital Signs and Symptoms for the Diagnosis of Serious Infections in Acutely Ill Children in a High Prevalent Setting: The Paediatric Accidents & Emergencies through prospective observational data collection concerning specific items from the clinical and technical examination in diagnosing serious infections, such as meningitis, sepsis, pneumonia, pyelonephritis, bronchiolitis with hypoxia. Eventually we will attempt to validate a vital signs and symptoms rule derived from multiple low to high prevalent settings of acutely ill children.
Acute respiratory infections are the leading cause of hospitalization in premature infants worldwide. Severity rates are particularly high in developing countries. Numerous viruses can cause severe disease, but the most frequent agent of hospitalization is respiratory syncytial virus (RSV). In a recent study in Argentina, 58% of RSV infected VLBW infants required hospitalization and 19% required mechanical ventilation. One every twenty infected infants died. Unlike industrialized nations, VLBW infants in developing countries often lack access to prophylaxis against RSV with a commercially available monoclonal antibody (palivizumab). No vaccine or preventive intervention is available against any respiratory virus for infants younger than 6 months of age in developing countries and the public sector of most middle-income countries. The protective role of breastfeeding against respiratory infections in developing countries is well established. But while similar beneficial effects have been described for premature infants, the dropout rate for breastfeeding in families exposed to the uncertainties and stress of the early months of life in the neonatal intensive care unit is very high. The World Health Organization recommends the use of Human Milk Donor Banks to feed infants that cannot be breastfed by their own mothers. These banks are established with the purpose of collecting, screening, processing (including pasteurizing), testing and distributing donated human milk. The potential benefit of donated milk against acute disease elicited by RSV is unknown. The investigators propose to study the role of supplemental donated human milk in the prevention of hospitalizations caused by RSV in non-breastfeeding premature infants. Since the investigators expect the benefits of breast milk to extend beyond protection against RSV, the effect of human milk against respiratory infections elicited by other viruses will also be evaluated.
Respiratory virus infections are a common cause of COPD exacerbations and antiviral therapies have potential as treatments for exacerbations. However it is likely that treating patients when they present with an exacerbation with antiviral drugs will be too late to be effective and earlier treatment at the time of the initial upper respiratory tract infection (URTI) will be required. The incidence of exacerbations following URTIs in COPD patients, and whether there are host factors and biomarkers that can identify the risk of this, is unknown. The aims of this study are to establish the proportion of viral URTIs that progress to an acute exacerbation in COPD patients and identify clinical, viral and biological markers that predict risk of an exacerbation following an URTI. In addition we will determine the frequency of, and risk factors for, bacterial infection following viral URTIs in COPD patients. This data will permit development of a model combining baseline patient characteristics, clinical measurements and biomarkers to predict exacerbation risk following viral URTI in COPD patients. The results will open the way for trials of antiviral therapy in COPD exacerbations and targeting of treatment to high risk patients.
Vaccines against human papillomaviruses are now commercially available. One of the commercial vaccine contains antigens of both LR HPV types which cause virtually all cases of RRP. Clinical trials have documented the safety and immunogenicity of this vaccine as well as its effectiveness in prevention of incident and persistent infection of the vaccinal types as well as a development of lesions caused by these types. After vaccination the antibodies level increases dramatically and the high levels of antibodies are present in the blood still after 6 years. Furthermore, the neutralization antibodies to the vaccinal antigens have been detected in the cervical mucus of vaccinated women. The preliminary data are now available showing the presence of HPV-specific antibodies in the oral cavity in women after vaccination. The level of antibodies has been dependent on time since vaccination.
Background: Respiratory endoscopy comprises flexible bronchoscopy and medical thoracoscopy. The diagnostic yield, technical factors and complications for all patient sub-populations is still not clearly defined. This may result in inappropriate or even dangerous application of such procedures. The aim of the study is to collect data on these aspects of respiratory endoscopy and identify important trends, as well as, areas for improvement. This data will also provide baseline comparative data for new bronchoscopic techniques such as endobronchial ultrasound and navigational bronchoscopy. Method: Prospective data collection. Technical details regarding these procedures are currently keyed into the OTM system by the endoscopy operators for documentation and billing. The department of Respiratory and Critical Care Medicine gets monthly downloads of all the fields from the OTM system for audit purposes.(See data collection form) The research project proposes to make the data non identifiable by removing the patient's name and IC number. Additionally the yield of the procedure will be checked by a chart review of the histology and microbiology results. There are no restrictions on patient recruitment because all procedures will be performed for clinical indications only and no patient will be recruited for the sole purpose of the study. Waiver of consent has been approved by the IRB.
The general hypothesis is that delayed antibiotic treatment strategies present similar effectiveness, when compared with non-prescription of antibiotics or the prescription of antibiotics, in the non-complicated acute respiratory tract infections.
Antimicrobial resistance has become a world-wide problem and antibiotic consumption is a major driving force for the development of resistance. Thus optimization of antibiotic prescription and reduction of unnecessary antimicrobial treatment are essential in the prevention and reduction of antimicrobial resistance rates. The goal of this study is the improvement of antibiotic prescription in outpatient care. The study will take place within a Swiss-wide sentinel surveillance network of physicians. The participating physicians will be randomised in a control and intervention group. The intervention group will receive therapeutic guidelines for the treatment of upper and lower respiratory tract infections and lower urinary tract infection as well as regular feed-backs on the prescription pattern of the sentinel physicians during the past months. Sentinel physicians will collect information about each antibiotic prescription, its indication and characteristics of the patient. Our hypothesis is that the prescription pattern in the intervention group will be optimised and unnecessary antibiotic therapy will be reduced compared to the control group.
GSK is conducting a global retrospective chart review of patients treated with zanamivir as part of the Compassionate Use Program (CUP), in an effort to collect as much information as possible on the use of this investigational drug. The retrospective chart review is intended to gain a better understanding of the safety profile of investigational zanamivir and of clinical outcomes in the large number of patients treated outside of a clinical trial setting.
The purpose of this study is to investigate the benefits of giving filled prescription of a medication to be used upon early onset of symptoms of URTI induced asthma. The hope is to reduce the need to present to Health Care centres for treatment.
