Background The aim of this study was to identify independent risk factors for cerebrospinal fluid shunt infection. Methods The medical records of all patients aged 0–18 years who underwent shunt‐related surgery for the treatment of hydrocephalus at the present institution between January 1996 and December 2015 were reviewed. For each case, two randomly selected controls with no shunt infection, matched for year of surgery, were chosen. Demographic clinical and microbiological data were abstracted. Results A total of 1,570 shunt‐related procedures met the inclusion criteria, yielding 68 infections (in 63 patients). The control group consisted of 132 infection‐free patients. The average annual infection rate was 4.2% cases per year. The median time between shunt procedures to infection was 19 days (range, 1–2,181). On multivariate analysis, risk factors associated with increased risk for developing an infection included a history of two or more previous revisions (OR, 4.8; 95%CI: 1.5–15.9); and age <5 years (OR, 4.5; 95%CI 1.5–13.4). A neoplastic etiology for hydrocephalus was found to be a protective factor for shunt infection (P = 0.001). Conclusions A history of shunt revision was the most significant risk factor in the development of subsequent shunt infection. Age >5 years was a protective factor. Future efforts should focus on modalities to optimize revision procedures and reduce the risk of subsequent infection.
Background: Pott’s puffy tumor (PPT) is a rare complication of frontal sinusitis. Although it may occur at any age, the incidence is higher during adolescence. Methods: We report a series of 10 pediatric patients (9–17 years of age) who presented with PPT in 2 tertiary care pediatric hospitals in central Israel between January 2018 and August 2022 and review the published literature on pediatric PPT. Results: The most common clinical presentations included headache (10 cases), frontal swelling (6 cases) and fever (5 cases). Symptom duration before admission was between 1 and 28 days (median 10 days). The diagnosis of PPT was made by imaging studies at a median of 1 day after admission. All 10 patients underwent computed tomography studies, and 6 patients also underwent magnetic resonance imaging. The overall rate of intracranial complications was 70%. All 10 children were treated with systemic antibiotics and surgical interventions. Streptococcus constellatus group was the most common causal bacteria. All 10 patients recovered uneventfully. Conclusions: Our findings show that a high index of suspicion for PPT should be applied to adolescents presenting with prolonged headache and frontal swelling. Contrast-enhanced computed tomography is an appropriate first tool for the evaluation; however, an magnetic resonance imaging should be performed to determine the necessity of intracranial interventional treatments if there is any suspicion of intracranial involvement. Complete recovery can be expected with appropriate antibiotic treatment and surgical intervention in most of the cases.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
