  • Suppurative Intracranial Complications of Pediatric Sinusitis: A Single-Center Experience. Journal of the Pediatric Infectious Diseases Society Otto, W. R., Paden, W. Z., Connors, M., Joerger, T., Buzi, A., Rizzi, M., Huh, J., Storm, P., Heuer, G., Kennedy, B., McGuire, J., Swami, S., Lang, S. S. 2021; 10 (3): 309-316

    Abstract

    Suppurative intracranial complications of sinusitis are rare events in children and can lead to harmful neurologic sequelae and significant morbidity. We sought to review the presentation and management of patients admitted at our hospital with these conditions.This was a retrospective study of pediatric patients admitted to a quaternary children's hospital from 2007 to 2019 for operative management of sinusitis with intracranial extension. Clinical characteristics, including surgical and microbiological data, were collected and analyzed.Fifty-four patients were included; the median age was 11.0 years, and there was a male predominance. Eighty-nine percent of patients had prior healthcare visits for the current episode of sinusitis; 46% of patients had an abnormal neurologic exam on admission. Epidural abscess and subdural empyema were the most common complications, and subdural empyema was associated with repeat surgical intervention. The dominant pathogens were Streptococcus anginosus group organisms (74%). The majority of patients completed treatment parenterally, with a median duration of therapy of 35 days. Neurological sequelae, including epilepsy or ongoing focal deficits, occurred in 22% of patients. History of seizure or an abnormal neurological exam at admission were associated with neurological sequelae.Clinicians should consider intracranial complications of sinusitis in patients with symptoms of sinusitis for >1 week. Patients should undergo urgent neuroimaging, as neurosurgical intervention is essential for these patients. Subdural empyema was associated with repeat neurosurgical intervention. Neurological sequelae occurred in 22% of patients, and new onset seizure or an abnormal neurological exam at admission were associated with neurological sequelae.

  • Murine macrophage inflammatory cytokine production and immune activation in response to Vibrio parahaemolyticus infection. Microbiology and immunology Waters, S., Luther, S., Joerger, T., Richards, G. P., Boyd, E. F., Parent, M. A. 2013; 57 (4): 323-8

    Abstract

    Vibrio parahaemolyticus is the most common cause of bacterial, seafood-related illness in the USA. Currently, there is a dearth of published reports regarding immunity to infection with this pathogen. Here, production of both pro- and anti-inflammatory cytokines by V. parahaemolyticus-infected RAW 264.7 murine macrophages was studied. It was determined that this infection results in increased concentrations of IL-1α, IL-6, TNF-α and IL-10. Additionally, decreases in cell surface TLR2 and TLR4 and increases in T-cell co-stimulatory molecules CD40 and CD86 were discovered. The data presented here begin to identify the immune variables required to eliminate V. parahaemolyticus from infected host tissues.

    Abstract

    Few of the proteins isolated and characterized from snake venom have proven to be more chemically diverse, exquisitely specific or promiscuously active than the family known as disintegrins. These small proteins have shown structural homology with hundreds of cell surface molecules from plants and animals other than snakes, and their precise mimicry of native receptor ligands speaks to evolutionary niches related to survival and geographic locale. Over 100 disintegrins have been named and studied, with the most recent efforts into molecular techniques providing significant clues to taxonomic relationships among four different snake families. Investigators have evaluated disintegrin applications in therapies for cancer, asthma, osteopenia and inappropriate angiogenesis. Crystal and NMR studies have confirmed hypotheses regarding ligand-receptor interactions while illuminating the complexities of structure-function evidence. Disintegrin chimeras with viruses, microbubbles and fluorescent labels have become useful tools in many investigations. While many disintegrin studies still involve platelets, previously unexplored interactions with glial cancer, T lymphocytes and the bacteria Yersinia have blazed new trails for this field. This review will summarize disintegrin investigations since 2003.
