Filter by:Application of isolation (=contact precautions) in hospitalized patients is recommended when patient is colonized (or infected) by micro-organism known for its outbreak capacity or high pathogenicity. It allows the reinforcement of universal precautions (=standard precautions) in order to control patient-to-patient micro-organisms transmission. Recently, the efficacy of this measure is questioned and its impact on patient care seems deleterious. In a particular context of Infectious Disease Unit, where standard precautions are handled (favorable architecture and appropriate practice for hand hygiene), assessment of contact precautions to reduce the incidence of acquired bacteria during hospitalization would be of interest. The investigators design a non-inferiority comparative study to measure the colonization pressure in patients hospitalized in two different parts of the department: one unit only with standard precautions applied (intervention) and one unit with contact precautions (control) as current routine care.
The investigators examined the outcome of patients with severe Enterohaemorrhagic E. Coli (EHEC) O104:H4 infection suffering from bloody diarrhoea that were at risk to develop hemolytic uremic syndrome and underwent repetitive whole bowl lavage during hospitalization.
This study will test the safety and tolerability of HCV Entry Inhibitor ITX 5061 in Liver Transplant Recipients with Hepatitis C infection. The investigators hypothesize that ITX 5061 oral monotherapy will be safe in adults during and after liver transplantation and that therapy will also inhibit HCV infection of newly transplanted livers in adults with prior HCV infection.
Corneal diseases are a major cause of blindness worldwide, and corneal infections are a substantial cause of blindness in Asia. The aim of the Asia Cornea Society Infectious Keratitis Study (ACSIKS) is to study infectious keratitis (corneal infections) in Asian countries, so as to improve strategies for prevention and treatment, and to reduce the burden of blindness in Asia. The first phase of ACSIKS is an 18-month observational study involving 11 eye hospitals in 8 Asian countries; these hospitals manage more than 6700 cases of corneal infections every year. From the first quarter of 2012, all patients with a corneal infection will be recruited and a standard ACSIKS protocol will be applied; this protocol includes the use of a common set of study forms and a suggested panel of microbiological examinations. However, each centre will be continue to treat their patients with the anti-infective therapy standard for their centre. Data will be recorded for each patient for a period of six months, including their medical and surgical management, the final clinical outcome and vision. Bacterial and fungal growths from patients will also be stored for further research during a second phase of ACSIKS. These studies will focus on evaluating the resistance of the most common bacterial infections to the current available antibiotics, performing DNA testing to compare our strains with bacterial infections in the West, and to developing new diagnostic tests and anti-infective therapies tailored to corneal infections in Asia.
Objectives: This study aims to characterize severe skin and soft tissue infections (SSTIs) in the emergency department through the acquisition of ultrasound images. A wide range of SSTIs will be imaged and recorded, leading to a registry of these infections. The registry will show whether ED (emergency department) sonographers can accurately characterize these infections, as compared to the final hospital diagnosis. The registry will also provide data for a case-control study comparing ultrasonographic characteristics of necrotizing skin and soft tissue infections (NSTIs) to those of non-necrotizing SSTIs. Research procedures: In this study, the investigators will approach patients who present to the Emergency Department with a possible skin and/or tissue infection. Study subjects must be ED patients requiring admission to the hospital for the primary problem of an SSTI due to the need for follow-up. If the patient consents to participating in the study, the investigator will obtain and record an ultrasound image of the infected area. An ultrasound image of an uninfected area of skin will also be recorded for comparison. Patient information regarding personal history, physical examination, blood tests and x-rays will also be gathered from participants.
The purpose of this study is to evaluate the effectiveness of bacteria called Lactobacillus GG, a Probiotic, in preventing the growth of resistant bacteria in the digestive tract in patients on a ventilator.
This is a feasibility double-blind randomised controlled trial in 32 participants. It evaluates the feasibility of a full trial which will examine the efficacy of weekly supplementation of cholecalciferol (vitamin D3) relative to placebo on the subsequent frequency and severity of objectively-verified symptomatic acute respiratory tract infection, overall and as a proportion of detected colonisations of the upper respiratory tract by 9 of the most common aetiologic viral pathogens.
Background: - Lymphatic filariasis is an infection that is caused by small, thread-like worms. It is spread by mosquitoes, and causes fever, chills, and headaches. If untreated, it can also cause elephantiasis, a condition that leads to swelling of the arms, legs, breasts, and scrotum. Treatment can eliminate the worms from the blood and reduce the risk of developing elephantiasis. Researchers want to study people with latent tuberculosis (TB) who may or may not be infected with filariasis. This study will look at the way that people with latent TB fight infection with these worms. Objectives: - To study how the immune systems of people with latent TB react to filarial infection. Eligibility: - Individuals between 18 and 65 years of age who have latent TB and may or may not have filarial infection. Design: - Participants will be screened with a physical exam and medical history. They will provide a blood and stool sample to test for infection. - Participants who do not have lymphatic filariasis but have another kind of intestinal worm will be treated for the parasite. This will be their last study visit. - Participants who have latent TB and lymphatic filariasis will be treated with the standard treatment for the disease. They will come back for a second visit 6 months later, and will provide another blood sample.
The purpose of this study is to determine rates of sexually transmitted infections (STIs) among African American women who have sex with women (AAWSW). In addition, the study is interested in better understanding the types of risk behaviors that place AAWSW at risk for STIs. The investigators hypothesis is that AAWSW experience high rates of STIs, similar to heterosexual African American women. Knowledge gained from this study will guide development of interventions to reduce women's risk for these types of infections and will improve how AAWSW are screened for STIs.
In neutropenic cancer patients, catheter-related bloodstream infections may cause severe infections and even death. To assess the prophylactic effect of a chlorhexidine coated catheter securement dressing on the incidence of catheter-related bloodstream infections, this open, randomized trial is being carried out. CHG iv Tegaderm securement dressing will be randomized in a 1:1 fashion against Tegaderm Advanced iv securement dressing.
