Filter by:General Objective : To evaluate the outcome of non surgical periodontal therapy with local drug delivery adjunct to scaling and root planning Specific Objective : To determine the effect of intra-pocket application of hyaluronic acid /chlorohexidine gel in non surgical periodontal treatment on clinical periodontal parameters and microbiological level .
The aim of this study is determining the additional effect of a 2-week home usage of chlorhexidine in periodontitis patients undergoing scaling and root planing supplemented with a dual-strain probiotic lozenge.
Hospital-acquired infections (HAI) have been shown to increase length of hospital stay and mortality. Infections acquired during a hospital stay have been shown to be preventable. The skin of patients is considered a major reservoir for pathogens associated with hospital-acquired infections, and has been suggested as a potential target for interventions to reduce bacterial burden and subsequent risk of infection. The use of daily Chlorhexidine (CHG) bathing in intensive care patients has been advocated to reduce many of the infections in critically ill patients. However, the effectiveness of CHG bathing to reduce ICU infections has varied considerably among published trials, making the effectiveness of CHG bathing in ICU patients uncertain.
PENGUIN is a pragmatic multi-center trial investigating the effects of pre-operative mouthwash and perioperative oxygen on the incidences of pneumonia and surgical site infection (SSI) following major abdominal surgery. Patients will be recruited from low and middle income countries and randomly assigned to a trial treatment arms: a) pre-operative chlorhexidine mouthwash and 80-100% FiO2; b) no pre-operative mouthwash and 80-100% fraction of inspired oxygen (FiO2); c) pre-operative chlorhexidine mouthwash and 21- 30% FiO2; or d) no pre-operative mouthwash and 21-30% FiO2.
The primary objective of this 6 month study is to compare the effectiveness of oral health promotion interventions on both clinical oral health, and oral opportunistic respiratory pathogens in institutionalized elders. Secondary objectives are to investigate changes in oral health-related quality of life, incidence of adverse side effects, pneumonia, as well as subject acceptability. Elders residing in nursing homes in Hong Kong will be recruited into the clinical trial. Patients will be randomly allocated into one of the following groups: 0.2% chlorhexidine spray, 0.1% pH-balanced chlorine dioxide spray, or sterile water spray (placebo control), once daily. Dental plaque, gingival bleeding, oral opportunistic respiratory pathogens, oral health-related quality of life (OHRQoL), and pneumonia incidence will be assessed at baseline, 3 months and 6 months. Subject acceptability of the interventions will be assessed at the end of the clinical trial.
This study will assess the utility of different chlorhexidine mouthwash concentrations on ICU patients to decolonize their oral cavities from gram-negative bacteria, since this is a non-desirable condition that leads to higher mortality rates and longer hospitalization times. One group will receive the 0.12% chlorhexidine mouthwash and the other group will receive the 2% chlorhexidine mouthwash.
Ventilator-associated pneumonia (VAP) is the most frequent life-threatening nosocomial infection in the ICU. Oropharyngeal colonization with bacterial pathogens is the first step toward lung infection. Oral hygiene with Chlorhexidine mouth wash (CMW) is among the most widespread preventive measure to prevent VAP. Precise microbial documentation of CMW efficacy on oropharyngeal colonization is lacking. Investigators wish to determine CMW antimicrobial efficacy in ICU ventilated patients and to measure chlorhexidine residual concentration in patients' saliva at the same time-points after CMW.
Recent meta-analysis have suggested that the safety of oral care with chlorhexidine in patients under mechanical ventilation could be questionable. Whatever the hypothetical mechanisms involved (direct cellular toxicity, underdiagnosis of Ventilator-Associated Pneumonia), presence of chlorhexidine in tracheal secretions after routine oral care is the cornerstone of this potential side effect of the routine oral care with chlorhexidine gluconate. The DEMETER study assessing the medico-economical impact of the subglottic secretions drainage study (NCT02515617) provides the opportunity to perform this proof of concept study (detection of chlorhexidine in tracheal secretions after routine oral care with chlorhexidine gluconate) and to evaluate the impact of the subglottic secretion drainage on this potential detection of chlorhexidine. This ancillary study will be performed in one of the centers participating to the DEMETER study.
Background (brief): 1. Burden: Neonatal death still unacceptably high in low income countries. The common causes of neonatal death are pneumonia, sepsis and omphalitis. Many neonatal infections occur because the mother's hands or the hands of the person who attended the birth are unclean. Our previous study found that there was substantial concern about excessive exposure of the mother or the neonate to water during handwashing because of the perception that frequent contact with water could lead to respiratory illness. 2. Knowledge gap: Chlorhexidine has been evaluated for use in hand hygiene applications in high-income countries, particularly in healthcare, but it has not been evaluated or promoted for hand cleansing at the household level in low- and middle-income countries. 3. Relevance: A waterless hand cleanser employing chlorhexidine would overcome important barriers to handwashing with soap, perceptions of cold resulting from exposure to water, and the time limitations perceived by mothers. Hypothesis: Mothers who are exposed to a chlorhexidine-based hand cleansing intervention will clean their hands (with chlorhexidine or soap and water) more frequently than mothers who are not exposed to the chlorhexidine-based hand cleansing program. Objectives: The primary objective 1. To demonstrate the behavioural impact of chlorhexidine-based hand hygiene intervention on hand cleansing of mothers during the neonatal period The secondary objectives 2. To demonstrate the impact of chlorhexidine-based hand hygiene intervention on hand cleansing of other family members, visitors to the neonate, and birth attendants during the neonatal period 3. To evaluate the acceptability of chlorhexidine for hand cleansing in the neonatal period among mothers, other family members, and birth attendants Methods: We propose a randomized controlled trial in a rural area of Bangladesh, with an active control. Randomization will be at the level of the participating pregnant woman. Each arm will include 150 participants. All intervention visits will follow baseline data collection. A trained health and hygiene promoter will carry out two visits in the antenatal period and one postnatal visit to deliver intervention messages. Outcome measures: 1. Observed hand cleansing behavior of mother with chlorhexidine or soap and water at critical times. 2. Observed hand cleansing behavior of other household members and visitors to home with chlorhexidine or soap and water at critical times.
