Streptococcus pyogenes is a Gram-positive beta-hemolytic bacteria, also known as group A streptococci, that causes a range of infections. The most common presentation is acute pharyngitis; however, it is also implicated in skin and soft tissue infections, and less commonly bacteremia, osteomyelitis, pneumonia, otitis media and sinusitis. Group A streptococci infections of the central nervous system are exceedingly rare in the antibiotic era. The mechanism of infection is typically contiguous spread from existing infection or via direct inoculation...

OBJECTIVES: Sepsis guidelines recommend obtaining blood cultures before starting anti-infective therapy in patients with sepsis. However, little is known how antibiotic treatment prior to sampling affects bacterial growth. The aim of this study was to compare the results of blood cultures drawn prior to and under antibiotic therapy. METHODS: Prospective clinical cohort study of septic patients. Adult ICU patients with 2 or 3 blood culture (BC) sets at the beginning of sepsis between 2010 and 2017 were included...

Current evidence reveals that surgical patients are more prone to adverse events when compared to any other population in the acute care setting. In a military training hospital, handoff communication between surgical intensive care unit (SICU) nurses, physicians, and anesthesia providers (certified registered nurse anesthetists and anesthesiologists) about patients being prepared for surgery was identified as a problem by an initial inquiry of the staff. This article discusses an evidence-based project (EBP) that utilized a standardized multidisciplinary Situation, Background, Assessment, Recommendation (SBAR) tool to improve communication, teamwork, and the perception of a patient safety culture between the SICU nurses and physicians and the anesthesia providers in preparation for surgery...

Acute-on-chronic liver failure (ACLF) is a newly recognized clinical syndrome characterized by preexisting chronic liver disease or cirrhosis with organ failure and high 28-day mortality (50-90%). Bacterial infections (BIs) play pivotal roles in the development and progression of ACLF either as a main precipitating event or a specific complication. The main organisms isolated as triggering ACLF are Gram-positive bacteria, followed by Gram-negative bacteria. Spontaneous bacterial peritonitis, pneumonia, urinary tract infections, and skin infections are prevalent infections that trigger and complicate ACLF...

OBJECTIVES: Overuse of broad-spectrum antibiotics in emergency departments(EDs) results in antibiotic resistance. We determined if procalcitonin(PCT)-guided therapy can be used to reduce antibiotic regimens in EDs by investigating efficacy, safety and accuracy. METHODS: This was a noninferiority multicenter randomized clinical trial, performed in two Dutch hospitals. Adult patients with fever ≥38.2°C(100.8°F) in triage were randomized between standard diagnostic workup(control group) and PCT-guided therapy, defined as standard workup with addition of one single PCT measurement...

BACKGROUND: In randomised controlled trials, procalcitonin (PCT)-guided antibiotic treatment has been proven to significantly reduce length of antibiotic therapy in intensive care unit (ICU) patients. However, concern was raised on low protocol adherence and high rates of overruling, and thus the value of PCT-guided treatment in real clinical life outside study conditions remains unclear. In this study, adherence to a PCT protocol to guide antibiotic treatment in patients with severe sepsis and septic shock was analysed...

BACKGROUND: During the conflicts in Iraq and Afghanistan, more than 52,000 U.S. military members were wounded in action. The battlefield mortality rate was lower than in past conflicts, however, those surviving often had complex soft tissue and bone injuries requiring multiple surgeries. This report describes the rates, types, and risks of infections complicating the care of combat casualties. PATIENTS AND METHODS: Infection and microbiology data obtained from the Trauma Infectious Disease Outcomes Study (TIDOS), a prospective observational study of infections complicating deployment-related injuries, were used to determine the proportion of infection, types, and associated organisms...

BACKGROUND: Necrotizing soft tissue infections (NSTIs) are severe and rapidly spreading soft tissue infections of the subcutaneous tissue, fascia, or muscle, which are mostly caused by bacteria. Associated rates of mortality and morbidity are high, with the former estimated at around 23%, and disability, sequelae, and limb loss occurring in 15% of patients. Standard management includes intravenous empiric antimicrobial therapy, early surgical debridement of necrotic tissues, intensive care support, and adjuvant therapies such as intravenous immunoglobulin (IVIG)...

Empyema necessitans (EN) is a rare phenomenon that refers to an insidious extension of the empyema through parietal pleura and subsequent dissection into subcutaneous tissue of the chest wall. A 29-year-old man presented to the hospital with fever and chills a few days after an inadvertent needle stick while injecting heroin. His left forearm was warm with an area of fluctuance. He underwent incision and drainage of the left forearm abscess with fluid submitted for Gram stain and culture. His condition rapidly deteriorated due to sepsis, and he required transfer to the intensive care unit...

Background: Meeting antibiotic stewardship goals in the neonatal intensive care unit (NICU) is challenging because of the unique nature of newborns and the lack of specificity of clinical signs of sepsis. Antibiotics are commonly continued for 48 hours pending culture results and clinical status. The goal of this study was to examine if the implementation of a 48-hour automatic stop (autostop) order during NICU admissions would decrease antibiotic use at UnityPoint Health-Meriter. Methods: An observational double-cohort study was performed in a level 3 NICU...

BACKGROUND: Sepsis remains a significant cause of morbidity and mortality in the United States, leading to the implementation of the Severe Sepsis and Septic Shock Early Management Bundle (SEP-1). SEP-1 identifies patients with "severe sepsis" via clinical and laboratory criteria and mandates interventions, including lactate draws and antibiotics, within a specific time window. We sought to characterize the patients affected and to study the implications of SEP-1 on patient care and outcomes...
