Active clinical trials for "Communicable Diseases"

Routine antibiotics for the intravenous and oral prophylaxis of colorectal surgery will be used. Experimental group: Patients undergoing elective colorectal surgery that involves, colonic resection. The antibiotic prophylaxis in this group will be composed of: An oral antibiotic pattern of ciprofloxacin (750mg / 12h, 2 doses) and metronidazole (250mg / 8h, 3 doses) the day before surgery. + Control group: Patients undergoing elective colorectal surgery that involves, colonic resection. The antibiotic prophylaxis in this group will be composed of: An intravenous antibiotic pattern of cefuroxime 1g and metronidazole 1,5gr during anesthetic induction. In both groups a second intravenous dose of cefuroxime (750mg) will be administered if the intraoperative time elongates more than three hours or there is an intraoperative bleeding over 1000cc. There won´t be a placebo treatment. Subject compliance will be evaluated according to the usual practice in surgical care field

Total joint replacement is a common clinical practice for patients suffering from disabling arthritis, since it provides significant pain relief and functional recovering. Nevertheless, its outcome is compromised by complications such as periprosthetic joint infection (PJI), which is reported to occur in 1 to 4% of primary total knee arthroplasties (TKA), and approximately 1% of primary total hip replacements (THR). Despite all efforts to restrain PJI, its prevalence may reach even higher proportions if patients undergo a resection arthroplasty or irrigation and débridement for infected prosthesis. That said, timely diagnosis and early isolation of the infected microorganism is utterly important, if proper care is to be delivered. The gold standard for the diagnosis of PJI is the isolation of a microorganism from the intraoperative cultures, combined with the sonication from retrieved joint implants1. This technique applies sound energy to agitate and disrupt biofilm, dislodging adherent bacterias to the bone cement, which has been proved to be a more sensitive method than conventional intraoperative cultures. False-negative percentages were reported to be 15% in patients who did not receive extended antibiotic prophylaxis and 60% if extended antibiotic therapy was administered. Regardless of an adequate clinical, radiographic and surgical suspicion confirming PJI, an organism is not always successfully isolated from the intraoperative cultures, which increases false negatives results. This fact has been trying to be explained by several authors, some of which postulate that antibiotic prophylaxis could interfere with the isolation of the microorganism from the intraoperative cultures. As a result, and acting accordingly to this hypothesis, preoperative antibiotics are often withheld until intraoperative cultures are obtained, hoping that tissues are not loaded with antibiotics. Nevertheless, one should be aware of the adverse consequences of this practice that may result in systemic dissemination of infection. Moreover, Ghanem and Stephen recently concluded that antibiotic prophylaxis does not interfere with the isolation of the microorganism from intraoperative cultures, despite being studies that lack statistical power. Therefore, it is clear that reported studies in this field support both preoperative antibiotic prophylaxis administration, as well its withdrawal, until intraoperative cultures are obtained. This decision in the department study depends exclusively on the treating surgeon judgment. In fact, 48% of all patients admitted at the study hospital with PJI receive preoperative antibiotic prophylaxis, which could be related to higher false-negative intraoperative culture and sonication results. Thus, the investigators add substances with chelation properties to hemoculture containers and then inoculate sonication samples. This practice offsets antibiotic interference with intraoperative cultures and has proved to enhance microorganism detection rates. That said, and given the lack of scientific evidence about this clinical practice the investigators are willing to engage a prospective randomized double-blind clinical trial, that will allow us to determine whether intraoperative cultures and sonication samples are affected by antibiotic prophylaxis.

Community-Acquired Pneumonia (CAP) of children are a recurrent pathology with multiple severity scores. The etiology is never really identified, and the initial treatment is always based on probabilistic antibiotics, in the case of an bacterial infection, and by the way, potentially severe. Molecular tests ("multiplex") allow the simultaneous detection of a huge number of pathogenic agents, virus and bacteria, are now available. This project is based on a new strategy of diagnostic, using a multiplex PCR with quick results, coupled to an antigenic urinary test to allow a complete, quick, etiologic diagnostic as soon as children are supported in emergency. Children are randomized in two groups during inclusions : quick diagnostic strategy versus usual practice. Analyse will be centralized on anti-infectious treatment optimization, with the aim to better treat patients, minimize the costs, and decrease selection pressure of multi-resistant bacteria.

The patients were randomized into 3 groups: those patients undergoing a ionic silver-containing dressing (ISD) (Group 1), those undergoing a Mupirocin ointment application (MOA) (Group 2) and those using a conventional dressing (Group 3) in the surgical wound after finishing an elective colorectal surgery.

The purpose of the study is to investigate additional clinical uses for the polymer, which is a FDA approved, 510k, medical device, but has not been approved for use on patients with pin track sites as a way to lower the infection rate and is investigational for this purpose. The approved uses include wound care and post-operative care. About 13 subjects will take part in this study.

The purpose of this study is to determine if closure of deep neck infection incisions at the time of extraoral drain removal has any impact on rates of reinfection and to determine if this treatment will have any impact on scar formation and qualitative measures of pain or impact on quality of life during the post-operative healing period.

The aim of this study is to evaluate the serologic response in patients with S. stercoralis infection after treatment with a regimen of two single doses of 200 µg/kg of ivermectin given 2 weeks apart versus a regimen of two single doses of 200 µg/kg of ivermectin given in two consecutive days.

From the profiles of antibiotic susceptibility data following eradication therapy, tetracycline, amoxicillin and levofloxacin are all good candidates of antibiotics used in the rescue treatment.

This investigational study will be conducted to evaluate the performance of the NeuMoDx™ CT/NG Assay on the NeuMoDx™ 288 Molecular System and NeuMoDx™ 96 Molecular System (collectively referred to as NeuMoDx™ CT/NG Assay test system).

Investigators designed an open, two-arm study to compare fecal microbiota transplant by oral capsules (FMT-c ) versus FMT-c enriched with Lactobacillus for treatment of C. difficile recurrent infection
