Active clinical trials for "Communicable Diseases"

The purpose of this study is to compare urinary tract infection rates among women undergoing urogynecological procedures with a silver-alloy suprapubic catheter compared to the standard suprapubic catheter.

Approximately 10-27% of patients undergoing gynecologic surgeries develop a catheter associated urinary tract infection (CAUTI) in the post operatory period, as bladder catheterization is a common practice in gynecologic surgery. Cranberry products provide alternative means for preventing CAUTI and could result in decreased use of antimicrobials. In this pilot study we will enroll 200 women post gynecologic surgery and randomize them to take either cranberry powder capsules or placebo powder capsules. The low risk of harm associated with using cranberry to reduce UTI coupled with its potential benefit makes it a desirable intervention for the prevention of CAUTI. The conduct/ results of this pilot /feasibility study will prepare us for the conduct of a large scale clinical trial.

Infectious pleural effusion is a classic complication of pneumonia and often require pleural drainage. There is no consensus between surgical drainage and medical drainage indication in first intention to treat an empyema. Usually surgery is proposed in second intention after failure of medical drainage. Videothoracoscopy is well accepted in diagnosis and treatment of pleural pathologies. The morbidity of this approach is very low with good results and become the gold standard in different pleural diseases. The medical drainage can be also very efficient but its results depends of the evolution of the pleural effusion. The rate of failure is estimated around 25%. Then, the aim of our study is to compare surgical drainage and medical drainage in first intention. The first end-point will be the hospital stay (day). Hospital discharge will be strict, following different objective criteria of healing allowing comparison between these two approaches of drainage. To answer this question we will randomized 50 patients in 2 years with a multicenter recruitment.

Ten healthy volunteers will be recruited to receive either an autologous stool transplant or a saline enema to determine if autologous fecal microbiota therapy will be able to rapidly, and safely, restore a patient's fecal microbiome after antimicrobial exposure.

The objective of the study is to compare infection rates between primary, delayed primary and vacuum assisted closures in contaminated and dirty/infected laparotomy wounds.

At the University Hospital Basel, Switzerland, a simplified screening for group B streptococci (GBS) of vagina and perineum has been performed since several years. Reliable detection of GBS is critical to prevent GBS transmission during delivery with antimicrobial prophylaxis. Transmission of GBS to the neonate may otherwise lead to severe infection and complications in the neonate. Centers for Disease Control and Prevention (CDC) and other international organizations recommend a vaginal and additional rectal swab.We therefore aim to test this simplified screening against the international gold standard. Antibiotic resistant bacteria may reside in the genital tract of an expected mother and may be transmitted to the new-born during delivery. In case of infection of the pregnant woman or the neonate, application of standard antimicrobial treatment will insufficiently cover these extended spectrum beta-lactamase (ESBL) producing bacteria. Therefore, colonization with ESBL in pregnancy needs to be known to potentially deliver adequate antimicrobial treatment.

With aging of the general population and broadening indications, the number of pacemaker recipients is steadily increasing. The incidence of infections of the implanted material, a dreaded major complication, is also rising. The diagnosis is evident in presence of an abscessed pocket, cutaneous breakthrough of the pulse generator or vegetations attached to the lead. On the other hand, a proportion of patients present with less specific clinical manifestations and a pacemaker recipient may be recurrently hospitalized for an infectious disorder of unknown origin despite detailed investigations. Without proof of lead infection, removal of the system without confirmation of its infection is usually proposed, despite the known morbidity and mortality associated with the extraction procedure (0.5 to 2%). Positive culture of the leads implies that the leads were involved in the infectious process. In recent years, 18FDG-PET-CT scan has made promising contributions in different areas including imaging to detect infection at different organ sites. Absence of hyperfixation of the lead, identified by 18FDG-PET/CT scan may be an accurate sign of absence of pacing system infection. The extraction of intracardiac implanted material, when it is indicated by the current standard strategy, may result in negative bacteriological cultures in 10 to 25% of patients, even when they did not receive antibiotics before extraction. The hypothesis of the study is that a new strategy adding 18FDG-PET-CT to the current strategy may avoid or reduce these false-positives. Therefore it is hypothesized that the sensitivity of 18FDG-PET-CT will be high enough to avoid unnecessary extractions of uninfected leads, resulting in a high negative predictive value of the new diagnostic strategy incorporating 18FDG-PET-CT. The present study aims at providing valid estimates of diagnostic accuracy parameters of 18FDG-PET-CT, especially its sensitivity. For this clinical study, firstly, 18FDG-PET-CT exam will be performed in patients, with suspicion of pacing or defibrillation lead infection, hospitalized in cardiology unit; secondarily, an intervention for the extraction of the intra-cardiac material, under general anesthesia, will be practiced and then a bacteriological culture for extracted material will be required. The end of study visit is complete the last day of material extraction. The follow up will last 2 to 7 days.

Patients presenting with pelvic organ prolapse will be offered the use of a pessary. Vaginal estrogen cream treatment with the pessary will be randomized amongst the patients and patient satisfaction and complication rates will be assessed during follow-up.

The investigators earlier clinical study in 754 young Finnish men demonstrated a significant negative association of serum 25-OHD concentration with acute respiratory tract infections. The present study aimed to determine whether vitamin D supplementation may decrease the incidence of acute respiratory tract infections.

The present study was to evaluate the usefulness of a whole-blood interferon-r release assays (IGRAs) as diagnostic tool of the latent tuberculosis infection for healthcare workers.
