Filter by:The investigators are aiming to learn more about respiratory infections in young children in the community. To prepare for a larger project, the investigators are conducting this study to get information about the best way to collect and transport respiratory specimens from young children. The investigators would like to test whether parents are more likely to collect a simple respiratory specimen themselves during a child's illness, compared to the likelihood of specimen collection when a home visit is made by a health care worker. Further, the investigators want to compare the likelihood a virus will be identified in both groups.
Parents with children aged 3-11 will participate in this study. About 500 children will take part in the study. We expect about half of those children will develop symptoms of a respiratory infection. Active participation in this study will last 14 days after a parent reports symptoms of a respiratory infection in a participant. Those children who do meet the study criteria of symptoms will then be randomly placed (like a flip of a coin) into one of 2 groups to take either COLD-FX® or placebo for 3 days. A placebo will look exactly like COLD-FX® but contains no active ingredients. The participant has an equal chance of being placed in either of the above groups. The study is double-blind, so neither the participant nor the study staff will know which study group the participant was placed in until the study is completed. If this information is needed in an emergency at any time throughout the study, it is quickly available from the sponsor. Participation in the study will be for 14 days after symptoms of a respiratory infection are reported to study staff. Your child will take the study product for 3 days, you will complete a daily diary, receive 4 phone calls and be seen for a final study visit to review the diary and complete a final health check of your child.
The purpose of this study is to conduct a Randomized Control Trial (RCT) in a developing country setting in order to evaluate the role of alcohol based hand sanitizers (ABHS) in preventing the transmission of infectious diseases in areas where water is a scarce resource. The investigators want to find out if the use of ABHS reduces the incidence of two leading causes of morbidity and mortality in children under 5 years of age in the developing world: acute diarrheal disease (ADD) and acute respiratory infections (ARI).
The purpose of this study is to determine if a patient education in acute condition about the intake of oral solution antibiotic in children under 6 year-old are effective to improve the satisfaction about the therapeutic education, the knowledge about antibiotics among the patients' families and thereby decrease the misuses of antibiotics.
The objective of this study was to obtain data on the safety, tolerability and compliance with Zithromax in children with bacterial infections of the upper and lower respiratory tract.
The aim of the study is to see if lozenges containing a low dose of interferon-alpha can prevent and/or reduce the severity of colds and flu. Starting about 1 month before the expected start of the winter colds and flu season in Perth, Australia, healthy volunteers will allow a lozenge containing interferon, or a lozenge containing no medicine (a placebo), to dissolve in their mouth once a day for 16 weeks. Blood tests at the start and end of treatment will determine whether interferon was able to prevent infections with cold/flu viruses. Once a week, volunteers will complete a survey about their cold/flu symptoms, medications taken, days of work missed, etc. to see if interferon was able to make their winter colds and flu less severe.
Upper respiratory tract infections (URTIs) are the most common illnesses in primary medical services but there is no established cure for these conditions in Western medicine. In Hong Kong, many patients use Chinese herbal medicine (CHM) for the treatment of URTIs but there is little research evidence on their effectiveness or side effects. The aim of this study is to test whether two commonly used Chinese herbal medicine (CHM) formulae guided by Traditional Chinese medicine (TCM) diagnosis will significantly increase recovery rate, and reduce the duration and/or severity of symptoms, and improve the quality of life of patients with URTIs in primary care. If a patient consents to take part in the study and is found eligible, he/she will be invited by the consulting doctor, and then be assessed by a registered Chinese medicine practitioner for whether the illness satisfies the TCM diagnosis of the two major TCM types of URTIs: Group A (Wind-cold syndrome) and Group B (Wind-heat syndrome). Subjects in Group A (Wind-cold syndrome) will be randomised to receive the Jing Fan Bai Du san or placebo. Subjects in Group B (Wind-heat syndrome) will be randomised to receive Ying Qiao san or placebo. Both group A and B treatments and placebo will be given in sachets of granules that are identical in appearance. Neither the Chinese medicine practitioner, the recruiting doctors, nor patient know whether a subject is taking CHM or placebo. 328 subjects (164 in each diagnosis group) will be recruited from patients consulting the Ap Lei Chau Government General Outpatient clinic for URTIs. Each subject is required to return to the clinic for follow-up assessment by the Chinese medicine practitioner on day 7 post-treatment and all subjects will be contacted by telephone on Day 2, 3, 5, 9, 11, 13,15 and 20 after treatment to assess their symptoms and to find out if they have developed any side effects or adverse reactions. The main outcome measure is any difference in the proportion of subjects who have resolution of the URTI on Day 7 between the treatment and placebo groups. The secondary outcome measures are the reduction in the duration and severity of symptoms, quality of life during the illness and side effects. This study will provide scientific evidence to support or refute the effectiveness of two commonly used CHM formulae in the treatment of URTIs.
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.
