We present the case of a 32-year-old woman with a left empyema and T12 osteomyelitis resulting from group B Streptococcus infection occurring 3 weeks after instrumental delivery of a healthy boy. Empyema is a rare complication of instrumental delivery, and this patient highlights the maternal risk resulting from group B Streptococcus bacteremia.

Background: Streptococcus mutans is recognized as a key pathogen responsible for the development of dental caries. With the advancement of research on dental caries, the understanding of its pathogenic mechanism has gradually shifted from the theory of a single pathogenic bacterium to the theory of oral microecological imbalance. Acidogenic and aciduric microbial species are also recognized to participate in the initiation and progression of dental caries.

Introduction: Group B Streptococcus (GBS) is an opportunistic pathogen that can induce chorioamnionitis (CA), increasing the risk of neurodevelopmental disorders (NDDs) in the offspring. The placenta facilitates maternal-fetal communication through the release of extracellular vesicles (EVs), which may carry inflammatory molecules such as interleukin (IL)-1. Although the role of EVs in immune modulation is well established, their specific characterization in the context of GBS-induced CA has not yet been investigated.

Background: Pneumococcal conjugate vaccines (PCVs) introduced in childhood national immunization programs lowered vaccine-type invasive pneumococcal disease (IPD), but replacement with non-vaccine-types persisted throughout the PCV10/13 follow-up period. We assessed PCV10/13 impact on pneumococcal meningitis incidence globally.
Methods: The number of cases with serotyped pneumococci detected in cerebrospinal fluid and population denominators were obtained from surveillance sites globally.

Purpose To study the incidence, clinical features, microbiology, and visual outcome of endophthalmitis associated with glaucoma surgery in children at a tertiary care eye hospital in Saudi Arabia. Methods The medical records of patients <18 years of age who presented with endophthalmitis following glaucoma surgery between January 2008 and October 2018 were reviewed retrospectively. Results Endophthalmitis after glaucoma surgery was observed in 20 eyes, or 18 out of 853 eyes that underwent glaucoma surgery at our institution (2.
