Filter by:Complicated appendicitis, characterized by the presence of an abscess or perforation, involves acute inflammation of the peritoneum secondary to an infection of the appendix, presenting additional challenges for management. Traditionally, the standard treatment for complicated appendicitis has been surgical intervention. However, conservative management, involving antibiotics and drainage, has emerged as a viable alternative for selected patients. Recent studies emphasize the importance of selecting appropriate antibiotics based on local resistance patterns and the patient's clinical condition. Broad-spectrum antibiotics, including those targeting anaerobic bacteria, are often preferred. In addition, advances in imaging technology, such as ultrasound-guided drainage, have improved the precision and success rates of percutaneous abscess drainage. This minimally invasive approach helps manage localized infections and can prevent the need for immediate surgery. One factor that has gained significant attention in determining the success of conservative treatment for acute complicated appendicitis is the presence of appendicoliths-calcified deposits within the appendix. This study aims to investigate the clinical significance of appendicoliths in the conservative management of acute complicated appendicitis with abscesses.
The purpose of this study is to evaluate if neuraxial anesthesia (epidural or intradural anesthesia) used during childbirth is associated with more frequent infectious complications in patients with primary immunodeficiencies (PID).
Pilonidal disease is a common disease characterized by the presence of abscess in the intergluteal groove. During periods of abscess, current recommendations are to make a simple incision with daily wicking of the abscess. Direct excision at this time is not recommended because there is a risk of incomplete excision. The principle of directed healing after incision of the abscess results in an average dressing period of 21 days. A definitive resection is recommended after 4 to 6 weeks, when healing has been achieved, in order to limit the risk of infectious recurrence. An alternative has recently been proposed, consisting of a puncture of the abscess, aimed at emptying it under antibiotic coverage. The major advantage of this treatment is that patients no longer need general anesthesia to flatten the abscess. Although this technique is promising, it is currently not the subject of any published or ongoing randomized controlled study registered on Clinicaltrials.gov. The research hypothesis is that the two techniques have the same results in terms of recurrence before definitive surgical treatment but that drainage puncture would imply a faster healing time, a lower cost of treatment, a quality of superior support, reduced support time and reduced work stoppage.
Allotransplantation is the process of transferring organ(s), tissue(s) or cell(s) from a healthy donor to a recipient. The two main applications of allotransplantation are solid organ transplantation and allogeneic hematopoietic stem cell transplantation. For several reasons, including the need to use immunosuppressive drugs after transplantation, recipients of allografts carry a high risk of infectious complications. Central nervous system infections are dreadful complications of transplantation, which can be divided into brain abscesses, meningitis, and encephalitis. In particular, brain abscesses pose major diagnostic and therapeutic challenges to transplant physicians, and are frequently fatal in transplant recipients. As compared with immunocompetent patients, transplant recipients and other immunocompromised patients have an increased risk of brain abscesses due to opportunistic pathogens, including fungi, parasites, bacteria, and mycobacteria. Determining the epidemiology of brain abscesses is critical to guide transplant teams regarding the diagnosis and management of brain abscesses in transplant recipients. Because the incidence of brain abscesses is low after transplantation, transplant teams often have limited clinical experience in the management of these infections. Similarly, most publications focusing on post-transplant brain abscesses are either case reports, small case series, or review articles. We therefore aim to conduct a multicentre retrospective study on the epidemiology, the characteristics, and the outcome of brain abscesses in transplant recipients in the era of new diagnostic tools and progress in prophylaxis.
assessment of healing potentiality of peri apical lesions using different doses of trypsin and alpha chemo trypsin in mandibular molars with chronic apical abscess
The goal of this cluster randomised controlled trial (cRCT) is to to evaluate the effectiveness of an educational intervention combining training in hand-washing with the supply of MONO-RUBs on the reduction of skin abscesses (both observed and self-reported) in people who inject drugs (PWID). The main questions it aims to answer are: - does an educational intervention change the incidence of injection-related skin and soft tissue infection (SSTI) like abscesses in PWID? - does the educational hand-washing intervention improve injection practices in terms of hand-hygiene in PWID? According to cluster randomisation, PWID will be assigned to: - Standard harm reduction (HR) services to reduce abscesses plus an educational hand-washing intervention (intervention arm) - Standard HR services only (control arm) To measure the effectiveness of the educational hand-washing intervention, the primary outcome will be the reduction in abscess prevalence compared in both groups. Statistical analyses for the primary outcome will involve comparing the reduction in abscess prevalence in the intervention arm with that in the control arm. This prevalence will be measured from observed and self-declared data, collected from the injection-site photographs and the face-to-face injection-related SSTI questionnaire, respectively.
The objective of this Phase 2 study is to evaluate the efficacy of methylene blue photodynamic therapy (MB-PDT) performed at the time of percutaneous abscess drainage for disinfection of deep tissue abscesses. The study includes three arms: (1) MB-PDT at a fixed drug/light dose plus standard of care abscess drainage , (2) MB-PDT at a patient-specific dose determined by pre-treatment optical measurements plus standard of care abscess drainage , and (3) standard of care abscess drainage. The primary endpoint is reduction in bacterial burden from pre- to post-intervention, quantified by culture of abscess aspirates.
This observational study aims to learn more about complicated infections treated by otorhinolaryngologists. The main questions to answer are: - What is the management of complicated sinonasal infections in Ljubljana, Slovenia, - What is the management of complicated ear and temporal bone infections in Ljubljana, Slovenia, - What is the management of complicated neck soft tissue infections in Ljubljana, Slovenia, - What is the management of complicated laryngeal infections in Ljubljana, Slovenia Participants will receive standard treatment according to the established evidence-based clinical practice.
The goal of this observational study is tolearn the association of gut microflora with the onset of perianal abscesses. The main questions it aims to answer are: Question 1: To understand the structure of rectal microbial community composition and its relationship with pathogenic bacteria in patients with perianal abscess. Question 2: Understand the structure of rectal microbial community composition in healthy people. Participants will be collected with rectal secretions and stool specimens.In addition, patients with perianal abscess should also collect pus samples.
Peritonsillar abscesses are major infections around the tonsils. The abscess is a collection of pus that can cause a large amount of pain and discomfort, which can result in trouble swallowing and drinking. Peritonsillar abscesses must be treated because they can spread to other areas in the throat and neck, which can cause difficulty breathing, can even spread throughout the rest of the body. Over the years, many different treatments have been used for peritonsillar abscesses. In the past, the entire tonsil was removed in the operating room while the patient was asleep. This surgery can cause a large amount of bleeding, and so now smaller surgeries are performed while the patient is awake. Small needles are put through the open mouth and into the abscess to drain it. As well, a small cut can be made to drain the infection. These last two treatments cause less problems than removing the whole tonsil, but there are still risks. The surgeries are uncomfortable for patients and they can cause anxiety and fear. There are also large blood vessels nearby that can be injured. In the last few years, treatment of peritonsillar abscesses without surgery has been studied. Patients receive strong antibiotics and anti-inflammatories (known as steroids) and they may not need surgery. It is not yet known if this treatment works as well as surgery. In order to figure this out, research must look at both options compared against each other in a large study with many patients. However, large research studies require a lot of planning, and so smaller studies are helpful to figure out if the larger study is even possible. The current study would be a small trial to plan for a larger study later on. Patients will be randomly treated with either medications alone or with surgery. The main part of the study will look at issues with planning the future study, such as how long it takes to fill out forms, how many missing results there are at the end of the study, and how patients and doctors feel about taking part in the research study. The future large study will look at how well the treatment options reduce pain, how fast patients are able to swallow normally again, how often patients need to change treatments, and whether there are differences in quality of life with the treatment options. Because these things will be looked at in detail in the future large study, the investigators will also look at them during this small planning study, but the investigators will not be able to tell for certain which treatment is better until the large study is completed. The results of this study are important for planning and performing the larger study, and they are important for getting future funding to do that study. Large studies are very expensive, and major funding organizations, such as the Canadian Institutes of Health Research, look for this early data when deciding who should get funding. The results of both this pilot study and the future larger study could be practice changing for how peritonsillar abscesses are treated, and will benefit both Nova Scotians and potentially the rest of world.
