Postoperative pain and time taken to return to normal activities after laparoscopic surgery are significantly shorter. Wound infections still occur and contribute to prolonged hospital stays and morbidity. Typically, port incision sites are covered with a standard dressing (approximating strips and a gauze). Although the umbilical wound infection rate in laparoscopic surgery is considered to be low, a recent study by Muensterer and Keijzer showed that the umbilical wound infection rate after single incision laparoscopic appendectomy in children is approximately 7%. In the same retrospective study, the investigators demonstrated that a simple low cost vacuum dressing can significantly reduce the infection rate. The aim of this prospective randomized controlled trial is to determine if the simple vacuum dressing is superior to a standard dressing in reducing laparoscopic postoperative umbilical wound infections. All patients under 17 years of age undergoing a laparoscopic operation in the Children's Hospital will be randomized to a standard postoperative dressing or a standard postoperative dressing with vacuum applied to it. The vacuum will be applied with a 22g needle on a 10ml syringe passed percutaneously from outside the dressing into the gauze and the air around the gauze is evacuated. The umbilical wounds will be evaluated 8-10 days postoperatively in the clinical research unit of the Manitoba Institute of Child Heath according to a standardized and validated wound evaluation tool from the Canadian Center for Disease Control. Primary outcome measure in this study is postoperative wound infection. A sample size calculation using the retrospective data demonstrated that the investigators need 275 patients in each group for the Chi-squared test to have an 80% chance of detecting a difference in wound infection rate of 6% at the 5% level of significance. Based on the annual number of laparoscopic operations in the Children's Hospital (around 400) the investigators anticipate completing the inclusion of patients within a two-year period.
This is a prospective cohort study of persons tested for latent tuberculosis infection at either high risk for exposure to Mycobacterium tuberculosis or high risk for progression to tuberculosis disease. The study will assess the relative performance and cost of three diagnostic tests for latent tuberculosis infection (tuberculin skin test, QuantiFERON-TB Gold In-Tube, and T-SPOT.TB) and will examine the rates of positive results among the cohort. This study will also determine the risk and rate of progression to active TB disease, overall and by the results of the three tests.
After open colorectal surgery the surgical site infection (SSI) is very high among abdominal surgeries. The goal of the investigators randomized, prospective, multicentric, internet-based study is to compare rate of SSI after surgery of colon and rectum by using triclosan-coated suture for abdominal wall closure. 180-180 cases in seven centres are involved in this study. Two arms are separated by computer randomization at abdominal wall closure: application of triclosan-coated and non-coated PDS suture (PDS versus PDS-Plus). Triclosan is an antiseptic material which the investigators hope will provide better local infection control at the site with reducing the risk of bacterial colonisation.
Infections related to implantable pacemakers or cardioverters defibrillators are sometimes difficult to be diagnosed. Diificulties in the diagnosis include a low sensitivity of standard markers of inflammation such as C-reactive protein or white blood cell count and the diagnosis is mainly based on the clinical presentation. The observational DIRT-study evaluates if new biomarkers may be more suitable to support a diagnosis of device associated infections than the currently available ones.
Impact exerted by intestinal parasitic infections is much higher in developing countries. School-aged children are at higher risk from the burden of disease, because they specially have many parasitic infections. The poor health results in deficits in physical and cognitive development and educational achievements. Nowadays, there is huge commitment among the global community to control intestinal parasitic infections and to improve nutritional status of young children in developing countries. Large-scale anthelminthic drug administration through vertical control programmes is still required for the foreseeable future and is, therefore, recommended by the World Health Organization (WHO). However, due to the inevitability of re-infection in endemic areas, children need to be treated regularly, and once morbidity control is consolidated, the strategy must shift to transmission control emphasising access to clean water and adequate sanitation. To lower dependency on 'drug only' approach and to enhance sustainability, from the onset of control activities, complementary measures should be implemented, that depend on available resources. Therefore, the investigators are proposing to undertake a randomised controlled trial to assess the impact of simple and easy-to-do hand hygiene intervention packages (hand washing with soap and hand finger nail clipping) on intestinal parasitic infection prevalence, intensity and re-infection rates and on haemoglobin concentration and anaemia prevalence rates among 6-15 years old schoolchildren. Our results will provide solid evidence on if and how hand hygiene practice affects infection prevalence and re-infection rates, as well as, anaemia prevalence among the highly vulnerable age group.
The purpose of this trial is to determine if exposure to ARV-containing investigational products in IPM clinical trials will impact the natural history of HIV infection as measured by the virologic, immunologic and clinical outcomes of participants who become HIV-positive during the IPM 027 trial.
Hospital-acquired infections are common complications in preterm infants. The diagnosis has to be fast and accurate. Indeed, the early identification of a suspected infection is very important, since the early administration of antibiotics lowers the risk of septic shock and improves long term outcome in the infected newborns who survive. Besides, a high specificity in the diagnosis of infection allows for the reduction of inappropriate treatment and thus prevents the emergence of antibiotic resistance. The aim of this study is to develop a computer-assisted diagnosis tool, based on the real time analysis of cardio-respiratory signals, to aid the neonatologist in the diagnosis of infection of the preterm infant, at the bedside.
Background: - Tuberculosis (TB) infection is particularly deadly when it happens in people who are also infected with the human immunodeficiency virus (HIV). However, not much is known about how these two infections affect each other. Some people who have HIV or TB infections develop health problems after they start taking either HIV or TB medications or both. These drugs can improve the body s ability to fight infections, but sometimes this sudden improvement can make the infected person initially become sicker. Researchers want to study how these infections affect the immune system and the gene expression of people who have TB and may or may not have HIV, to see if there is a pattern of gene expression that may predict whether people starting treatment may get sicker initially. Objectives: - To study the gene expression and immune systems of people with TB who may or may not also have HIV. Eligibility: - Adults at least 18 years of age who have tuberculosis. - Participants will be drawn from study sites in the United States and China. Design: - Participants will be divided into three study groups. The first group will have TB but not HIV. The second group will have both TB and HIV that have not been treated. The third group will have both TB and HIV that are currently being treated. - All participants will have a single study visit. Blood samples will be collected at this visit. A medical history will also be collected. - No treatment will be provided as part of this study.
This is a retrospective, multicentre, observational study to assess the trends in antibiotic utilization and hospital ecology with respect to susceptibility patterns of selected bacterial isolates to the utilized antibiotics.
