Neurosurgical infections

Guillain-Barré syndrome (GBS), an acute immune-mediated neuropathy, occurs following immunological stimulation, such as infection, with complement-mediated neuropathy implicated in the pathophysiology of this condition. Glycolipid antibodies produced by molecular mimicry are detected in approximately 60% of cases. Recent studies have suggested the role of cell-mediated immunity in the pathogenesis of GBS. Intravenous immunoglobulin and plasma exchange are established immunotherapies. In this article, based on the latest knowledge, we describe the pathophysiology, diagnosis, treatment, prognosis, and prognostic prediction of GBS...

OBJECTIVES: To determine the effectiveness and safety of Hemopatch® as a primary dural sealant in preventing CSF leakage following cranial surgery. Cerebrospinal fluid (CSF) leaks occur in cranial operations and are associated with significant patient burden and expense. The use of Hemopatch® as a dural sealant in cranial neurosurgical procedures is described and analyzed in this study. METHODS: Data were retrospectively collected from all patients who underwent a craniotomy for various neurosurgical indications where Hemopatch® was used as the primary dural sealant between June 2017 and June 2022...

INTRODUCTION: Brain tumors pose a major challenge in low- and middle-income countries (LMICs) due to limited resources and high costs, resulting in an hampered service delivery of neurosurgical care and significant disparities in patient outcomes compared to high-income nations. Therefore, our systematic review aims to identify barriers to service delivery in providing adequate surgical care for the management of brain tumors in LMICs. METHODS: We searched Scopus, PubMed, Google Scholar, and CINAHL, from inception to October 20, 2022...

BACKGROUND: Cerebrospinal fluid (CSF) shunts allow children with hydrocephalus to survive and avoid brain injury (J Neurosurg 107:345-57, 2007; Childs Nerv Syst 12:192-9, 1996). The Hydrocephalus Clinical Research Network implemented non-randomized quality improvement protocols that were shown to decrease infection rates compared to pre-operative prophylactic intravenous antibiotics alone (standard care): initially with intrathecal (IT) antibiotics between 2007-2009 (J Neurosurg Pediatr 8:22-9, 2011), followed by antibiotic impregnated catheters (AIC) in 2012-2013 (J Neurosurg Pediatr 17:391-6, 2016)...

OBJECTIVE: The insertion of a ventriculoperitoneal shunt (VPS) is a common neurosurgical procedure, but the optimal entry site of the ventricular catheter is still under debate. In this study, the authors compare the parietal (Keen's) and frontal (Kocher's) entry sites in terms of the rate of revision surgery due to ventricular catheter misplacement, VPS dysfunction, and VPS infection. METHODS: The authors retrospectively analyzed the data on consecutive adults (age ≥ 18 years) who had undergone primary VPS insertion between 2010 and 2020 at two neurosurgical centers...

OBJECTIVE: Infection after carotid artery stenting (CAS) is rare. We report two dialysis cases of delayed stent infection associated with a carotid dual-layer stent (DLS), which occurred several months after deployment of the stent. CASE PRESENTATIONS: Case 1 : A 74-year-old man receiving dialysis underwent CAS with DLS. Three months after CAS, the patient developed a high fever, neck pain, and neck swelling. Neck CT and carotid ultrasonography (CUS) indicated an abscess around the inserted DLS...

OBJECTIVE: Otitis media and sinusitis are common childhood infections, typically mild with good outcomes. Recent studies show a rise in intracranial abscess cases in children, raising concerns about a link to COVID-19. This study compares a decade of data on these cases before and after the pandemic. METHODS: This retrospective comparative analysis includes pediatric patients diagnosed with otitis media and sinusitis, who later developed intracranial abscesses over the past decade...

Surgery and endovascular therapy are the primary treatment options for spinal dural arteriovenous fistula (SDAVF). Due to the absence of a consensus regarding which therapy yields a superior outcome, we conducted a comparative analysis of the surgical and endovascular treatment of SDAVF through a multicenter case series and a systematic literature review. Patients with SDAVF, surgically or endovascularly treated at four neurosurgical centers from January 2001 to December 2021, were included in this study. Level of SDAVF, primary treatment modality, baseline and post-procedural neurological status were collected...

BACKGROUND: Severe perioperative hyperglycemia (SH) is a proven risk factor for postoperative complications after craniotomy. To reduce this risk, it has been proposed to implement the standardized clinical protocol for scheduled perioperative blood glucose concentration (BGC) monitoring. This would be followed by intravenous (IV) insulin infusion to keep BGC below 180 mg/dl in the perioperative period. The aim of this prospective observational study was to assess the impact of this type of protocol on the postoperative infection rate in patients undergoing elective craniotomy...

BACKGROUND: Aneurysms located in the distal middle cerebral artery (MCA) are relatively rare and lack an established treatment strategy. For distal MCA (DMCA) aneurysms, we performed a one-stage combined procedure of endovascular parent artery occlusion (PAO) with coils and superficial temporal artery to middle cerebral artery (STA-MCA) bypass in a hybrid operating room (HOR). The aim of this study was to evaluate the safety and efficacy of this procedure. METHODS: Cases of unruptured DMCA aneurysms treated with the one-stage combined PAO and STA-MCA bypass in HOR were retrospectively examined, and patients' and aneurysmal backgrounds, surgical procedures, and treatment outcomes were analyzed...

OBJECTIVE: There is limited consensus regarding management of spinal epidural abscesses (SEA), particularly in patients without neurologic deficits. Several models have been created to predict failure of medical management in patients with SEA. We evaluate the external validity of five predictive models in an independent cohort of patients with SEA. METHODS: 176 patients with SEA between 2010 and 2019 at our institution were identified, and variables relevant to each predictive model were collected...

INTRODUCTION: Dural closure is an important part of neurosurgery, failure which may lead to wound infection, pseudomeningoceles, meningitis, severe morbidity to a patient, and even mortality. In cases where primary dura closure is not possible, a bovine pericardial patch is a good alternative with the benefits of suturability and the ability to provide watertight closure, hence preventing Cerebrospinal Fluid (CSF) leak. The present study demonstrates the use of the bovine pericardial patch in both cranial and spinal disorders for dural closure as well as for transposition technique in microvascular decompression...

BACKGROUND/AIM: Dural reconstruction is a critical process after neurosurgical procedures. Improper dural repair leads to serious side-effects, such as cerebrospinal fluid leakage or infection. This is why it is important to properly repair the dura using a dural substitute, and research into dural substitutes is ongoing. The ideal dural substitute should be non-toxic, biocompatible, and capable of maintaining adequate tension and preventing cerebrospinal fluid leakage for extended periods in vivo...

BACKGROUND AND IMPORTANCE: Basal encephaloceles are the result of a concomitant cranial and dural defect that allows for inferior displacement of cerebral tissue, meninges, and cerebrospinal fluid into the paranasal sinuses and outside the cranial vault. This work illustrates a step-by-step surgical approach of a successful single-stage, endoscopic repair of a congenital basal encephalocele in a 10-year-old child, using a free mucosal middle turbinate graft that provided effective results without utilization of traditional open reconstructive techniques or vascularized flaps...

OBJECTIVE: We evaluated the contributions of chronological age, comorbidity burden, and/or frailty in predicting 90-day readmission in patients undergoing degenerative scoliosis surgery. METHODS: Patients were identified through the Healthcare Cost and Utilization Project Nationwide Readmissions Database. Frailty was assessed using the Johns Hopkins Adjusted Clinical Groups frailty-defining indicator. Comorbidity was assessed using the Elixhauser Comorbidity Index (ECI)...

BACKGROUND: Debate persists over the relative merits of Neuroendoscopic Surgery (NS) compared to Stereotactic Aspiration (SA) for treating supratentorial intracerebral hemorrhage (ICH). Consequently, we undertook this meta-analysis to assess the efficacy and safety of NS versus SA. METHODS: We searched for the all-relevant studies systematically from English databases including PubMed, Embase, Web of Science and the Cochrane Library. Three independent researchers identified and selected these literatures that met the inclusion criteria...

Meningitis and ventriculitis, due to carbapenem-resistant Enterobacterales , are frequently associated with significant morbidity and mortality. In the case of multi-drug-resistant pathogens, it is necessary to consider the limited susceptibility profile as well as the penetration of the antimicrobials into the brain. Limited data are available regarding the treatment of central nervous system infections caused by carbapenem-resistant Enterobacterales . We report a study of a patient treated with meropenem-vaborbactam in the case of post-neurosurgical meningitis due to carbapenemase-producing Klebsiella pneumoniae ( CPKP )...
