PTA is a collection of pus located between the tonsillar capsule and the pharyngeal constrictor muscle. It is considered a complication of acute tonsillitis and is the most prevalent deep neck infection (approximately 2000 cases annually in Denmark) and cause of acute admission to Danish ENT departments. Teenagers and young adults are most commonly affected and males may predominate over females. However, no studies of age- and gender-stratified incidence rates have previously been published. Furthermore, smoking may be associated with increased risk of peritonsillar abscess (PTA) development, although the magnitude of the association has not been estimated...

BACKGROUND: The current recommendation regarding the management of a term newborn delivered of a mother with an intrapartum fever or a diagnosis of clinical chorioamnionitis is that the neonate should have baseline laboratory work drawn along with blood cultures and be universally treated with antibiotics until culture results return. These guidelines report that the rate of intrapartum fever is about 3%; however, a few large studies suggest that the rate is higher at about 7%. OBJECTIVE: We sought to prospectively evaluate the rate of fever during labor in a large number of deliveries and determine the rate of early-onset neonatal sepsis in newborns delivered from mothers with an intrapartum fever compared with newborns delivered from mothers without intrapartum fever...

INTRODUCTION: Given the major impact in terms of morbidity and mortality that episodes of early neonatal sepsis (ENS) have on both newborns and health systems, this study aimed to identify the etiological profile of early neonatal bacterial sepsis by a multiplex quantitative real-time polymerase chain reaction (qPCR). METHODOLOGY: Blood samples from newborns diagnosed with clinical ENS and hospitalized in neonatal intensive care units (NICUs) were collected and analyzed using the multiplex qPCR method to detect Streptococcus agalactiae, Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, Enterobacter sp...

BACKGROUND: Infections by group B streptococci (GBS), e.g. Streptococcus agalactiae, presenting as early-onset disease (EOD) or late-onset disease (LOD), are leading causes of severe infections in newborn and premature patients. Although screening and intra partum antibiotic prophylaxis are frequently performed, vertically transmitted GBS remain a challenge for pediatrics. AIMS: In order to prevent or reduce potential life-threatening events, this study retrospectively investigated epidemiological, microbiological and clinical aspects of infants admitted to the Division of Neonatology at the Department of Pediatrics at the University Hospital Frankfurt, Germany (UHF)...

INTRODUCTION: Group B streptococcus (GBS) is the most common infectious agent responsible for early-onset bacterial sepsis (EOS) in term newborns. French prevention of perinatal GBS disease guidelines recommend screening for maternal vaginal GBS colonization at the 9th month of pregnancy, and use of intrapartum antibiotic prophylaxis (IAP) in case of detected GBS vaginal colonization. Peripheral bacterial sampling (gastric aspiration, ear, or meconium) and measurement of C-reactive protein (CRP) are performed in asymptomatic newborns in case of infectious risk factors and/or incomplete IAP...

OBJECTIVES: The objectives were to evaluate and compare the diagnostic accuracy of a rapid real-time PCR assay at the onset of labor with those of the current antenatal culture-based test at 34-38 weeks gestation for group B Streptococcus (GBS) screening. MATERIALS AND METHODS: A prospective study including all pregnant women admitted for delivery after a 34-week gestation period was conducted in October 2012 at the Grenoble University Hospital Centre. A first culture-based GBS screening test was performed between 34 and 38 weeks of gestation followed by a second screening test at the onset of labor, using a real-time PCR Assay and a culture-based method (gold standard) in order to calculate the diagnostic accuracy...

Group B Streptococci (GBS) are ß-hemolytic, gram-positive bacteria that are typically associated with infections in human newborns or immunocompromised adults. However, mutation in the two-component regulator CovR/S relieves repression of hemolysin, potentially increasing virulence of GBS. We report the isolation of hyperhemolytic/hyperpigmented GBS strain from an adolescent patient who presented to the University of Washington clinic with symptoms of sore throat. While the patient also tested positive for mononucleosis, a GBS strain with increased hemolysis was isolated from the throat swab obtained from the patient...

AIMS: Group B streptococcal (GBS) disease is the leading cause of early-onset neonatal sepsis in New Zealand. Disease follows vertical transmission of GBS from the mother, which can largely be prevented by intravenous intrapartum antibiotics. A 2004 New Zealand guideline recommended using clinical risk factors to identify mothers who would qualify for intrapartum antibiotics. An expert multidisciplinary group met to reconsider these guidelines in the light of a two year survey of the incidence of early onset GBS neonatal sepsis...

Early onset sepsis (EOS) is a worrisome, life-threatening condition in newborns with onset during the first week of life. Evaluation can be challenging due to the dynamic nature of the condition as the infant transitions to life ex-utero. Symptoms/signs can be nonspecific, thus, a high index of suspicion is warranted for subtle changes in condition including poor feeding, respiratory distress, or decreased activity. Common risk factors include chorioamnionitis, maternal fever, group B strep (GBS) colonization and preterm delivery...

BACKGROUND & OBJECTIVES: One of the important infectious factors in pregnant mothers and newborns is Group B Streptococcus (GBS). There is no perfect report about prevalence of GBS in Iran and in the case of preterm rupture of amniotic membrane or preterm labor all patients are treated by antibiotics without culture so this has led to adverse taking antibiotics and drug resistance. The present study is intended to determine the frequency of colonization of GBS in the pregnant mother (35-37 weeks), referred to medical centers of Shahed University...

INTRODUCTION: Early-onset neonatal infection remains a major cause of morbidity and mortality in neonates. Both universal vaginal screening for group-B streptococcus (GBS) and intrapartum antibiotic prophylaxis have decreased the incidence of early-onset GBS disease. Almost 12 years after the implementation of the French recommendations, we assessed the practices around screening, diagnosis, and treatment of early-onset neonatal infection in the Île-de-France region. PATIENTS AND METHODS: We conducted a prospective, multicenter, observational study in 14 volunteer maternity wards from 18 to 31 March 2013...

Universal screening for maternal group B Streptococcus (GBS) in the prenatal period has led to administration of intrapartum antibiotic prophylaxis (IAP). Although IAP decreased the rate of early neonatal GBS disease, exposure of childbearing women to penicillin and other beta-lactam antibiotics has increased. Beta-lactam-induced anaphylaxis in the breastfeeding woman during the postpartum period illustrates risk factors for beta-lactam allergy and anaphylaxis. Treatment and nursing implications for this adverse reaction are suggested...

Group B Streptococcus (GBS) is responsible for two distinct clinical syndromes in the newborn period categorised as either early- or late-onset GBS disease. Maternal GBS colonization of gastrointestinal tract or vaginal is the major risk factor for GBS diseases. There are two main strategies for identifying women at risk of giving birth to a GBS-infected infant: universal screening strategy and risk-based assessment. In the United States and other countries, the implementation of maternal intrapartum antibiotic prophylaxis policies has significantly reduced the incidence of early-onset neonatal GBS disease, but has little effect on the incidence of late-onset GBS disease...

UNLABELLED: Since the 1950s, beta hemolytic streptococcus group B have constituted the major etiological factor of perinatal infections. GBS colonization of the genital tract among pregnant women is diagnosed between 35 and 37 weeks of gestation, and is associated with approximately 25% risk of neonatal early-onset infections (EOD). The infection is severe among 1-3% of the newborns, and usually results in sepsis or pneumonia. beta-lactam antibiotics are drugs of choice to prevent vertical infection of group B streptococcus...

Group B streptococcus (GBS) remains worldwide a leading cause of severe neonatal disease. Since the end of the 1990s, various strategies for prevention of the early onset neonatal disease have been implemented and have evolved. When a universal antenatal GBS screening-based strategy is used to identify women who are given an intrapartum antimicrobial prophylaxis, a substantial reduction of incidence up to 80% has been reported in the USA as in other countries including European countries. However recommendations are still a matter of debate due to challenges and controversies on how best to identify candidates for prophylaxis and to drawbacks of intrapartum administration of antibiotics...

Group B Streptococcus (GBS) infections remain an important cause of perinatal complications, despite advanced preventive measures. The most common clinical symptoms of early-onset disease, diagnosed in neonates up to 7 days of life, are sepsis and pneumonia. Late-onset disease is diagnosed in children between 7 and 89 days of life and presents also in forms of other infections. As a result of collaborative efforts of clinicians, researchers and many organizations, various recommendations for intrapartum prevention of perinatal GBS disease have been issued so far...
