The aim of this retrospective study was to review the diagnostic accuracy of real-time polymerase chain reaction (PCR) testing of cerebrospinal fluid (CSF) samples for Streptococcus pneumoniae DNA in comparison with traditional bacterial culture. The hypothesis was that PCR is more sensitive than culture and would detect more cases of pneumococcal meningitis, particularly in children treated with antimicrobials before CSF sampling occurred. Patients younger than 16 years who had a CSF sample tested for S.pneumoniae DNA by PCR between 2004 and 2015 were included...

REVIEW
Adam Corey, Tsz-Yin So
The rate of antibiotic resistance in children continues to rise requiring the use of new antibiotics. Ceftaroline fosamil, a newer-generation cephalosporin, was recently approved for the treatment of acute bacterial skin and skin structure infections and community-acquired bacterial pneumonia in children aged >2 months. Ceftaroline provides coverage against staphylococcal and streptococcal infections, including methicillin-resistant Staphylococcus aureus and penicillin-resistant Streptococcus pneumoniae...

BACKGROUND: Although sickle cell disease (SCD) children are highly susceptible to bacterial infections (BIs), there is a dreadful lack of data related to the burden and spectrum of BIs in sub-Saharan Africa (SSA), the highest affected region with SCD. This study aimed to determine the burden and spectrum of BIs among SCD children hospitalized in a pediatric reference hospital in Cameroon, a SSA country. METHODS: We conducted a retrospective analysis of records of children hospitalized from November 2012 to August 2015 in the SCD unit of the Mother and Child Centre of the Chantal Biya Foundation, Cameroon...

Spontaneous acute subarachnoid hemorrhage (SAH) from lumbar ependymoma in children is rare. We report a case of a14-year-old boy who developed sudden radicular low back pain while playing baseball. He was initially managed conservatively in a local hospital for suspected lumbar disc herniation, but later developed meningeal symptoms and fever before being referred to our hospital. There he underwent a diagnostic lumbar puncture in the emergency room; his cerebrospinal fluid suggested an SAH. Physical examination showed meningeal signs and cauda equina features...

REVIEW
Andrew Janowski, Jason Newland
In the past century, advances in antibiotics and vaccination have dramatically altered the incidence and clinical outcomes of bacterial meningitis. We review the shifting epidemiology of meningitis in children, including after the implementation of vaccines that target common meningitic pathogens and the introduction of intrapartum antibiotic prophylaxis offered to mothers colonized with Streptococcus agalactiae. We also discuss what is currently known about the pathogenesis of meningitis. Recent studies of the human microbiome have illustrated dynamic relationships of bacterial and viral populations with the host, which may potentiate the risk of bacterial meningitis...

BACKGROUND: In sub-Saharan Africa, systematic surveillance of young children with suspected invasive bacterial disease (e.g., septicemia, meningitis) has revealed non-typhoidal Salmonella (NTS) to be a major pathogen exhibiting high case fatality (~20%). Where infant vaccination against Haemophilus influenzae type b (Hib) and Streptococcus pneumoniae has been introduced to prevent invasive disease caused by these pathogens, as in Bamako, Mali, their burden has decreased markedly. In parallel, NTS has become the predominant invasive bacterial pathogen in children aged <5 years...

BACKGROUND: Endogenous bacterial endophthalmitis is a rare but potentially devastating intraocular infection that can have severe sight-threatening complications. Most patients with endogenous bacterial endophthalmitis have underlying infectious conditions, such as diabetes or malignancy, which predispose them to infection. CASE REPORT: A 1-year-old girl presented with cloudiness of the right eye. Ocular examination showed a cloudy cornea in the right eye with conjunctival injection and hypopyon...

Central nervous system (CNS) tuberculosis (TB) is the most severe form of extra-pulmonary TB and disproportionately affects young children where the developing brain has a unique host response. New Zealand white rabbits were infected with Mycobacterium tuberculosis via subarachnoid inoculation at postnatal day 4-8 and evaluated until 4-6 weeks post-infection. Control and infected rabbit kits were assessed for the development of neurological deficits, bacterial burden, and postmortem microbiologic and pathologic changes...

Streptococcus pneumoniae is the main causative organism of acute media otitis in children and meningitis and bacterial pneumonia in the community. Since 2008 in Tuscany, central Italy, the pneumococcal conjugate vaccine (7-valent vaccine, switched to 13-valent vaccine in 2010) was actively offered free of charge to all newborns. Aim of the study is to evaluate the impact of pneumococcal pediatric vaccination in the Tuscan population on hospitalizations potentially caused by S. pneumoniae, during pre-vaccination (PVP, 2002-2007) and vaccination period (VP, 2009-2014)...

BACKGROUND: Meningococcal disease (MD) is a medical emergency and a serious public health problem. As new meningococcal vaccines become available, MD surveillance is crucial to provide baseline epidemiologic data before implementing preventive measures. We estimated MD incidence and epidemiology in Argentina using hospital-based surveillance. METHODS: Three-year prospective active surveillance in patients ≤15 years of age was conducted at 6 pediatric hospital sentinel units (March 2012 to February 2015)...

Neisseria meningitidis is one of the leading global causes of bacterial meningitis. Here, we discuss the draft genome sequences of two N. meningitidis strains, isolated from bloodstream infections in two pediatric patients at a tertiary care hospital in South India. The sequence data indicate that strains VB13856 and VB15548 encode genomes of ~2.09 Mb in size with no plasmids.

Among 831 cases of neonatal bacterial meningitis occurring from 2001 to 2013, Neisseria meningitidis was the third most frequent bacterial species found. All cases occurred only in term neonates and were mainly late onset. Serogroup B accounted for 78% of cases. At diagnosis, 27% of cases had at least one sign of disease severity. All strains were susceptible to cefotaxime, but 12% showed intermediate susceptibility to penicillin G and to aminopenicillin.

Meningitis is a life-threatening infection associated with a high mortality and morbidity worldwide. Neisseria meningitidis, Haemophilus influenzae, and Streptococcus pneumoniae are the most prevalent infectious agents that cause bacterial meningitis (BM). The objective of this study was to determine the frequencies of these three bacteria using bacterial cultures and polymerase chain reaction (PCR). In our cross-sectional study, cerebrospinal fluid (CSF) specimens were obtained from 196 patients who were suspected of having BM and referred to the pediatric ward of Abuzar Hospital (Ahvaz, Iran)...
