Haemophilus influenzae serotype A is a rare cause of meningitis and invasive disease in pediatric patients. A six-month-old infant presented to the emergency room with fever, cough and nasal drip. On admission, the infant was alert and hemodynamically stable but progressively became more lethargic with bulging of the fontanelle.

Evaluating altered mental status and suspected meningeal disorders in children often begins with imaging, typically before a lumbar puncture. The challenge is that meningeal enhancement is a common finding across a range of pathologies, making diagnosis complex. This review proposes a categorization of meningeal diseases based on their predominant imaging characteristics.

The functional specialization of CD4 T lymphocytes into various subtypes, including T1 and T cells, is crucial for effective immune responses. T cells facilitate B cell differentiation within germinal centers, while T1 cells are vital for cell-mediated immunity against intracellular pathogens. Integrin α4, a cell surface adhesion molecule, plays significant roles in cell migration and co-stimulatory signaling.

Miller Fisher syndrome (MFS) is a rare variant of Guillain-Barré syndrome (GBS) characterized by a classic triad of external ophthalmoplegia, ataxia, and areflexia, often following a recent infection. Understanding atypical presentations of MFS is crucial for timely diagnosis and management, as the syndrome may be mistaken for other neurological disorders. This report aims to highlight the clinical journey of the patient, including symptom onset, diagnostic challenges, and therapeutic interventions, with a discussion of the broader implications of such atypical cases in the context of MFS.

Background: Group A Streptococci (GAS) may cause infections of the pharynx and soft tissues and invasive infections in children (iGAS). A significant increase in severe iGAS infections has been reported in Europe since the fall of 2022.
Objectives: This retrospective study aims to analyse clinical data of children with invasive and non-invasive GAS infections in the post-COVID-19 pandemic era, searching for predisposing factors to developing invasive infections.

Fever among infants in the first months of life is a common clinical conundrum facing all clinicians who treat children. Most well-appearing febrile young infants have viral illnesses. However, it is critical to identify those at risk of invasive bacterial infections, specifically bacteremia and bacterial meningitis.

Oropouche fever, a mosquito- or midge-borne emerging zoonotic disease endemic to South and Central America, manifests as a dengue-like acute febrile illness with occasional occurrences of meningitis or meningoencephalitis. The causative agent, Oropouche virus (OROV), belongs to the genus Orthobunyavirus within the family Peribunyaviridae. Its tripartite negative-sense RNA genome comprises small (S), medium (M), and large (L) segments, encoding structural N, Gn/Gc, and L proteins, respectively.

Unlabelled: Viral aseptic meningitis is a neuroinflammatory condition that occurs when viruses gain access to the central nervous system (CNS) and induce inflammation. The blood-brain barrier (BBB) is comprised of brain endothelial cells (BECs) that stringently regulate the passage of molecules, toxins, and pathogens from the circulation into the CNS. Through their unique properties, such as complex tight junctions, reduced rates of endocytosis, expression of efflux transporters, and restricted expression of leukocyte adhesion molecules, the BBB is often able to limit pathogen entry into the brain; however, certain neurotropic pathogens, such as coxsackievirus B3 (CVB3) are able to infect the CNS.

Western equine encephalitis is a zoonotic viral disease transmitted by the bite of an infected mosquito. Humans are terminal hosts and since they develop a very low and short lasting viremia, they are incapable of transmitting the disease. Most cases are asymptomatic, but it can present with high fever, myalgia and encephalitis or meningitis.

During chronic infection or tumorigenesis, persistent antigen stimulation contributes to the exhaustion of CD8 T cells. Nevertheless, exhausted CD8 T (T) cells still preserve certain effector function, and maintaining a reservoir of exhausted cells is of vital importance for virus elimination and tumor eradiation. Despite considerable work interrogating the rejuvenation of T cells, mechanisms underpinning the clonal deletion of T cells remain largely unexplored over the past decade.

Fever is the most common complaint for children of all ages who present to an emergency department (ED) for evaluation and treatment. Although most children with fever have a self-limiting viral illness, the infant less than 60 days of age with fever poses a higher risk for an underlying serious bacterial illness (SBI) including urinary tract infections, bacteremia and bacterial meningitis, or an invasive bacterial infection (IBI) including bacteremia. This case is a discussion of a high-risk febrile infant that was evaluated in the emergency department and was ultimately diagnosed with Streptococcus B meningitis.

Background: Nigeria adapted the WHO package of care for Advanced HIV Disease (AHD) in 2020. The package includes CD4 + cell count testing to identify People Living with HIV (PLHIV) with AHD, screening and treatment of opportunistic infections, rapid antiretrovirals (ART) initiation, and intensive adherence follow-up. The national program adopted a phased approach in the rollout of the AHD package of care to learn lessons from a few representative health facilities before scaling up across the country.

We describe the proportion of VZV infection in central nervous system (CNS) infectious syndromes in a single Israeli medical center. An observational cohort study was conducted in Kaplan Medical Center (a secondary hospital, Israel) between July 1, 2014, and March 31, 2019. Included were adult patients (≥ 16 years old) with CNS infection with an aseptic CSF profile that were subjected to molecular tests for herpes viruses, HSV either 1 or 2, VZV, enteroviruses, and IgM for West Nile virus (WNV).

Neonates who develop fever have a high risk for serious infection, and while the standard of care involves performing a full sepsis evaluation, current guidelines do not include viral polymerase chain reaction (PCR) testing of the cerebrospinal fluid as a standard of care, which means that cases of viral meningitis can be missed. This case presentation discusses a neonate who had a fever at four days of life who then underwent a full sepsis evaluation. A respiratory viral panel demonstrated rhino/enterovirus positivity.

Enterovirus A71 (EV-A71) is a major cause of hand-foot-and-mouth disease (HFMD), particularly in cases that involve complications affecting the nervous system or cardiopulmonary function. In South America, EV-A71 has primarily been identified through studies of acute flaccid paralysis (AFP) and other neurological disorders. In September 2022, two children from a small city in Uruguay were hospitalized with presumptive rhombencephalitis, exhibiting symptoms of HFMD.

An increase in the number of herpes zoster patients has been reported since universal varicella immunization was introduced, perhaps because of reduced opportunities for varicella patients to experience the natural booster effect caused by reexposure. We investigated recent trends of varicella zoster virus (VZV)-related central nervous system (CNS) infections at a university hospital in Japan. We enrolled patients with suspected CNS infection during 2013-2022 and tested cerebrospinal fluid samples by real-time PCR for DNA from 7 human herpesviruses.

Objectives: Acute central nervous system (CNS) infections in children can lead to neurological complications and mortality. This study aimed to identify the clinical manifestations, laboratory parameters, and cerebrospinal fluid characteristics indicative of CNS infections and define the risk factors that lead to pediatric intensive care unit (PICU) admission in the pediatric population of Şanlıurfa, a city in southeastern Turkey.
Methods: This retrospective analysis included patients aged 1 month to 18 years who were treated for acute CNS infections in the Şanlıurfa Training and Research Hospital between January 2020 and May 2023.

The Arenaviridae family of segmented RNA viruses contains nearly 70 species with several associated with fatal haemorrhagic fevers, including Lassa, Lujo and Junin viruses. Lymphocytic choriomeningitis arenavirus (LCMV) is associated with fatal neurologic disease in humans and additionally represents a tractable model for studying arenavirus biology. Within cultured cells, a high proportion of LCMV spread is between directly neighbouring cells, suggesting infectivity may pass through intercellular connections, bypassing the canonical extracellular route involving egress from the plasma membrane.
