Hospital aquired infections

While most episodes of community-acquired pneumonia are caused by Streptococcus pneumoniae and respiratory viruses, other atypical pathogens can also be responsible for lung infections. The Infectious Diseases Service of the Lausanne University Hospital (CHUV) organizes an annual meeting aimed at general practitioners, during which interesting clinical cases are presented. In this article, we summarize five cases of community-aquired respiratory infection due to atypical pathogens that were presented during the 2023 meeting, each with a particular teaching point...

BACKGROUND: The present study was conducted to study the prevalence of HAIs in a newly established MICU, common microorganisms causing HAIs and their antibiotic-sensitivity profile, and antimicrobial utilization and mortality rate. METHODS: The present retrospective cohort study was carried out at AIIMS, Bhopal (2015-2019). The prevalence of HAIs was determined; sites of HAIs and common causative microorganisms were identified, and their antibiotic-sensitivity profiles were studied...

Objectives Immunocompromised patients, specifically those with solid organ transplants or cancer on chemotherapy, are at particularly high risk of severe pneumonia and opportunistic infections. In select patients, bronchoalveolar lavage (BAL) is performed to provide high-quality samples for analysis. We compare BioFire® FilmArray® Pneumonia Panel (BioFire Diagnostics, Salt Lake City, Utah, United States), a multiplex polymerase chain reaction (PCR) assay, with standard of care diagnostics in BAL samples from immunocompromised patients to identify opportunities for this test to affect clinical decision making...

BACKGROUND: The impact of environmental hygiene on the occurrence of hospital-acquired infections (HAIs) remains a subject of debate. We determined the effect of three different surface-cleaning strategies on the incidence of HAIs. METHODS: Between June 2017 and August 2018 we conducted a pragmatic, cluster-randomized controlled crossover trial at 18 non-ICU wards in the university hospital of Berlin, Germany. Surfaces in patient rooms on the study wards were routinely cleaned using one of three agents: Soap-based (reference), disinfectant and probiotic...

Central line-associated bloodstream infections (CLABSI) are a significant risk factor for poor patient outcomes. It is important to correctly diagnose and treat these infections to ensure the best chance of recovery. Kocuria rosea is a novel bacteria that is native to the human flora and has been on the rise as a culprit in recent nosocomial infections. However, due to its characteristics, it is often misclassified by commonly used hospital tests. We present a case of a 55-year-old female with sickle cell disease who developed a K...

BACKGROUND: Hospital-acquired conditions (HACs) are increasingly scrutinized as markers of hospital quality and are subject to increasing regulatory and financial pressure. Despite this, there is little evidence that HACs are associated with poor outcomes in traumatically injured patients, or that lower HAC rates are a marker of a better quality of care. Our study compares mortality rates in hospitals with high versus low rates of HAC. Our hypothesis is that high HAC trauma centers have higher mortality...

Background Nosocomial infections are a significant health concern. Following surgery, infections are most commonly associated with the surgical site, yet there are other potential sources for infections after surgical interventions. Identification of the source of infections can be very challenging. Methodology An outbreak of postoperative infections following surgery led to intensive care unit (ICU) admission of patients immediately after the surgical procedure. The blood cultures of two patients were positive for Citrobacter freundii ...

BACKGROUND: Children with life-limiting conditions have a high risk of colonisation with a multidrug-resistant organism (MDRO). To avoid the spread of hospital-aquired infections to other patients, children with a MDRO are moved to an isolated room or ward. However, such isolation prevents social participation, which may reduce the child's quality of life (QoL). To overcome this challenge of conflicting interests on a paediatric palliative care inpatient unit, a hygiene concept for patients colonised with MDRO, called PALLINI, was implemented...

AIM: To define the outcomes of persons with diabetes and foot ulcers (DFUs) managed through a specific triage pathway during the COVID-19 crisis. METHODS: Patients who had an active DFU during the COVID-19 emergency were included. All participants were managed using a specific triage system driven both by ulcer'severity and concomitant co-diseases. Subjects with severely complicated DFUs were urgently referred to hospital regardless of the concomitant comorbidities...

BACKGROUND: This is the first review to analyze literature identifying risk factors for a multidrug-resistant urinary tract infection (MDR UTI). Risk factors for other infections involving multidrug-resistant organisms have been evaluated in other reviews, but they do not assess urinary tract infections. The purpose of this study is to collect currently published data to determine the most commonly and consistently identified risk factors for UTIs. MATERIAL AND METHODS: For this study, 3 independent researchers searched PubMed, Embase, and Cochrane database from 1966 to February 2016 for articles identifying risk factors for MDR UTI...

BACKGROUND: Healthcare associated infection (HAI) is alarmingly increasing in low income settings. In Ethiopia, the burden of HAI is still not well described. METHODS: Longitudinal study was conducted from May to September, 2016. All wards of Jimma University Medical Centre were included. The incidence, prevalence and risk factors of healthcare associated infection were determined. A total of 1015 admitted patients were followed throughout their hospital stay. Biological specimens were collected from all patients suspected to have hospital aquired infection...

BACKGROUND: The incidence of Clostridium difficile infection (CDI) in nursing home residents is believed to be high because of the prevalence of predisposing factors such as decreased immune response, multiple comorbidities, medications, increased risk of infection, close proximity of residents, and recent hospitalization. Yet, specific information on CDI in this population is scarce.  OBJECTIVES: To investigate differences in clinical and demographic characteristics, treatment, and underlying comorbidities in residents who acquired CDI preadmission (non-nursing home-acquired [NNH-Acquired]) compared with those who acquired CDI after admission to a nursing home (nursing home-acquired [NH-Acquired]) and matched controls...

OBJECTIVE: To investigate the incidence, pathogens, and clinical features of infection in consecutive cases from 2010 to 2012 in Peking Union Medical College Hospital. METHOD: The incidence, pathogen, treatment, and outcomes of patients with hematological diseases who had positive findings of bacterium in their samples from 2010 to 2012 were retrospectively analyzed. RESULTS: There were 449 positive samples (5.8%) from 4 890 patients during this period, among which 388 were proved to be with pathogenic bacteria...

OBJECTIVE: To investigate the change of pathogen distribution and antibiotic resistance of pathogens isolated from in-patients with hospital acquired pneumonia (HAP) in the Department of Respiratory Medicine Intensive Care Unit (RICU) of Xiangya Hospital in 2005 and in 2011, and to provide reasonable anti-infectious strategy. METHODS: The positive susceptibility test of sputum (bronchial secretions) culture was done in patients with HAP in RICU of Xiangya Hospital in 2005 and in 2011, and the distribution feature and antibiotic resistance were compared...

According to the WHO pneumonia are the third leading cause of death in low-and middle-income countries. In these countries, an important issue are also HIV/AIDS infections and tuberculosis. The clinical picture of severe pneumonia - outside hospital (community aquired pneumonia - CAP) and in-hospital (hospital-associated pneumonia - HAP & ventilator-associated pneumonia - VAP) is different similarly to laboratory examines results. In the etiology of infections the biological warfare pathogens were also included...

Human babesiosis has been documented in many countries. It is a zoonotic protozoan disease of medical, veterinary and economic importance. In this study, a twelve years old boy was referred to the hospital with intermittent fever of unknown origin. On clinical, parasitological and serological bases the case proved to be babesiosis. The boy acquired the infection from his pet dog which was heavily infested with Rhipicephalus sanguineus and suffered a mild feature of animal babesiosis. The patient was successfully treated with Atovaquone plus Azithromycin without relapse for one month follow up...

BACKGROUND: Aquired immune deficiency syndrome (AIDS) presents a challenge to medical researchers because of its unique pathological and clinical picture. The clinical data, particularly autopsy evidence, from China have failed to provide enough pathological and etiological evidence for AIDS diagnosis, which impairs the reliability of the diagnosis and our full understanding of the occurrence and development of AIDS complications. The purpose of this study was to investigate the imaging and pathologic characteristics of AIDS...

Chronic neutropenia is a decrease in circulating neutrophils in the peripheral blood lasting over 6 months. Values need to be refered with the age and race. In children aged 2 weeks to 12 months reffered values are above 1000/03BCL. There are congenital and aquired reasons of neutropenia in infancy. The most common type of chronic neutropenia in infants is chronic, benign neutropenia (AIN). Authors present ten infants between three and six months with chronic, benign neutropenia. The reason of ordering laboratory tests at outpatient clinic were benign upper respiratory tract infections (four cases), pallor (four cases) and on parental demand (one case)...

Clostridium difficile-associated diarrhea (CDAD) is common among hospital-acquired bacterial diarrhea, its mortality and morbidity show an increasing trend in recent years. Improper antimicrobial drug use is one of the key reasons. Adequate hand hygiene of healthcare workers, thorough disinfection of hospital environment, and appropriate isolation of patients are effective measures to prevent the outbreak of hospital-aquired CDAD.
