Filter by:The goal of this study is to determine if Echinacea purpurea stimulates the immune system. For the study, 20 healthy adults will be randomized to receive Echinacea purpurea or placebo for 10 days. Blood will be drawn to assess immune markers just before beginning the study medication, during the 10 day course of medication and after completing the course of medication. It is postulated that adults receiving the Echinacea will have evidence of immune stimulation and those receiving placebo will not.
The purpose of this study is to determine if a commercially available homeopathic cold remedy for children is effective in providing relief from cold symptoms in children 2-5 years old. It is postulated that children will have relief of symptoms after receiving a dose of the cold remedy
Many children with "non-severe pneumonia" (cough and fast breathing) have neither clinical pneumonia as assessed by physicians nor pneumonia on chest radiographs. Inappropriate use of antibiotics for these cases is leading to resistant strains of bacteria in the community. Evidence shows that almost 50% of antibiotic prescription is unnecessary.As over half of antibiotic prescription for ARI are not necessary since most of these infections are viral and do not respond to antibiotic therapy which will be source of resistance in the community. To address this issue the investigators conducted this randomized, double blind placebo controlled clinical trial of oral Amoxicillin versus placebo in children with non-severe pneumonia taking into account all the necessary safety precautions for their well being. The study hypothesis was that the clinical outcome of children 2 to 59 months of age with cough and fast breathing (WHO defined non-severe pneumonia) with or without wheezing is equivalent, whether they are treated with amoxicillin or placebo.
The purpose of this study is to determine whether probiotic treatment improves the protection against respiratory infections after influenza vaccination in elderly living in nursing homes.
The purpose of this study is determine if topical oral application of a chlorhexidine antimicrobial spray will significantly reduce pneumonia and respiratory infections, and improve oral health compared to a placebo solution in nursing home residents.
The purpose of this study is to determine if administration of the HPV quadrivalent vaccine in patients diagnosed with RRP has a therapeutic effect on their clinical course. More specifically, does administration of the vaccine decrease the size and number of papillomas, severity of disease (i.e. hoarseness, inspiratory vs. biphasic stridor, airway obstruction) using the LCAS and time interval between required surgical debulking will be analyzed.
To assess effectiveness of Trulimax (Azithromycin) in Acute Bacterial Upper Respiratory Tract Infections (URTIs).
Observation of the initial Procalcitonin values and the clinical course of consecutively included patients with Acute Respiratory Tract Infections at general medical practices in greater Hannover.
Improved hand hygiene is known to reduce transmission of both respiratory (RTI) and gastrointestinal infections (GTI) under "semi-closed" conditions such as hospitals, day-care centres and schools. It is not known if similar interventions would have the desired effect in a regular office work. This study is aiming to investigate this possibility by recruiting volunteers from several companies in the Helsinki Region. The two intervention groups will receive detailed instructions e.g. for proper coughing and sneezing, and for regular cleaning of hands with either standard liquid soap or with alcohol-based gel rubbing. Third group will serve as the control and is advised not to change their previous behaviour in this respect. The participants will report weekly possible RTI or GTI symptoms and related days off through internet. The study is planned to run about 18 months to cover the seasonal variation of the epidemics of the causative different viruses.
The purpose of this study is to compare the safety and efficacy of dexibuprofen syrup and ibuprofen syrup in patients with fever due to common cold.
