Filter by:The purpose of the investigators project is to examine if the investigators may affect a reduction in respiratory infections in a pediatric long term care facility by institution of a comprehensive oral care program. The investigators wish to base their project on work such as of Yoneyama et al 2002, which hypothesized and showed that "silent" aspiration of oropharyngeal contents is a causative factor in development of respiratory infection in elderly institutionalized clients. It was found that an advanced oral hygiene program greatly reduced the incidence of respiratory infection. Although no similar research projects were found to have involved children, the investigators hope that a similar program of oral care will allow the investigators to likewise reduce the incidence of respiratory infection among the pediatric clients in our facility. The investigators propose to examine two groups of children which are fed by gastrostomy feedings only. One group will continue to receive oral care as performed today. The study group will have their teeth brushed three times a day by the nursing staff by using a suction connected toothbrush, daily examination of the oropharynx by the nursing staff, and use of chlorhexidine varnish or another suitable antibacterial agent in the oropharynx. The investigators will retrospectively examine our records (a 12 month period) for febrile days, antibiotic use and hospitalization days due to respiratory causes. The investigators will then compare these to the febrile days, antibiotic use and hospitalizations to the 12 month period [post implementation of the oral care program. The importance of this program is to examine whether by implementation of a relatively inexpensive and low-tech intervention may meaningfully reduce the morbidity and mortality due to respiratory infection among our clients (which from our experience is the main cause of morbidity and mortality in the investigators institution). The investigators expect that by reducing the incidence of respiratory disease among our clients that the investigators will greatly reduce suffering among the children and their families, improve their quality of life and ease the financial and organizational burdens as a result of caring for respiratory infections. As was noted before, no prior research was found which studied the pediatric population in a long term care facilities. It is our belief that this project represents a unique research opportunity which may bring great benefit to the children and caregivers.
The primary goal of this study is to characterize the pharmacokinetics of doxylamine succinate in children ages 2 to < 18 years. Once characterized, these pediatric pharmacokinetic data will be pooled with historical adult PK data from other studies to assess whether the existing Over-the-Counter (OTC)doses provide comparable systemic drug exposure as that associated with efficacy in adults.
The purpose of this study is to determine the safety, tolerability and pharmacokinetics of PF-04287881 after a single oral dose in healthy adult volunteers.
The goal of the this study is to determine if Echinacea purpurea stimulates the immune system in children. For the study, 40 healthy children, 6-11 years old will be randomized to receive Echinacea purpurea or placebo for 10 days in 3 consecutive months. Blood samples will be obtained in the children just before starting study medication, during the first course of medication and either just prior to starting the second course of medication or 50 days following the last of the three courses of medication. Markers of immune activity in children receiving Echinacea or placebo will be compared.
The purpose of this study is to determine the effectiveness of probiotics (popularly referred to as 'live active culture' or 'good bacteria') in preventing illnesses and consequent absences from school/daycare centers of children two to four years old that attend daycare at least 3 days per week. Two yogurt drinks will be administered, one containing a specific strain of probiotic, Bb-12. It is hypothesized that children receiving the Bb-12 drink will experience fewer illnesses and absences from daycare. In this study, participants will be asked to: 1. Give their child 4 oz. of the test yogurt each day for 90 days 2. Keep a daily diary of their child's health 3. Collect 3 stool samples from their child at the start, middle, and end of the study 4. Speak with research personnel on a bi-weekly basis regarding their child's health 5. Ensure that their child to consume any yogurts or probiotic-containing products for 110 days of the study
Aging is associated with a variety of changes in the immune system. These changes result in a less effective immune response, which places the elderly at a greater risk for infection and disease. Respiratory infections cause a great number of morbidity and mortality in the elderly population. Vitamin E has been known to improve the immune response of the elderly and has been suggested for use in preventative strategies for this population. The purpose of this study is to examine the effect of one year vitamin supplementation on respiratory infection in the elderly population residing in nursing homes. This study was conducted using a randomized, double blind, placebo controlled clinical trial at 33 long-term care facilities in the greater Boston area. A total of 617 subjects over the age of 65 were enrolled in the study, with 451 completers. The participants were supplemented wit either 200 IU of vitamin E per day or placebo. The primary outcomes consisted of respiratory tract infection, number of sick days, and antibiotic use. The study involved use of questionnaires, standard anthropometrics measurements, non-invasive body composition, blood and urine sample collection, and delayed type test (DTH) using the Mantoux method. This study has been closed since August 2000 and is in the stage of data analysis only.
RATIONALE: American ginseng extract may prevent or reduce acute respiratory illness in patients with chronic lymphocytic leukemia. It is not yet known whether American ginseng extract is more effective than a placebo in preventing respiratory infections. PURPOSE: This randomized trial is studying the side effects of American ginseng extract and to see how well it works compared with a placebo in preventing respiratory infection and in reducing antibiotic use in patients with chronic lymphocytic leukemia.
The purpose of this study is to evaluate the safety, effectiveness, and side effects of the CryoSpray AblationTM System (CryoSpray AblationTM, "CSA" or "cryospray therapy") to treat benign airway disease in the lung using liquid nitrogen sprayed through a catheter via flexible fiber optic bronchoscopy (FFB)
Background In preparation for a global influenza pandemic, there is an urgent need for representative data from populations and settings where the pandemic is most likely to arise. There are no data on oseltamivir efficacy from Asian urban slum populations concerning duration of illness and viral shedding, nor whether efficacy depends on starting treatment < 48 hours or ≥ 48 hours after illness onset. Finally, there are no data on the capacity of the drug, in such settings, to affect household and community transmission rates. Aims and Objectives This proposal aims to compare the duration of clinical illness among patients treated with oseltamivir vs placebo < 48 hours and ≥ 48 hours after illness onset. It will compare the duration of viral shedding among all treatment groups vs placebo, risk of transmission to household contacts by treatment group and whether neuraminidase inhibitor use creates resistance. Secondarily it aims to measure the effect on influenza. Design and Methods A double-blind placebo controlled clinical trial design among a population in an urban slum under current influenza disease burden surveillance will be enrolled. Infection status will be confirmed by rRT-PCR. Patients ≥ 1 year old will be randomised to < 48 hour and ≥ 48 hour treatment arms. Family members and neighbours will also be assessed by PCR and a basic reproductive number calculated (R0). Relevance These findings will address whether oseltamivir can affect illness duration and severity, affect transmission, incidence and resistance in high risk urban Asian settings where a pandemic is most likely to arise.
This study will test the hypothesis that constitutionally poorer Eustachian tube function predisposes to middle-ear pathology during a viral upper respiratory infection.
