Abstract Background Cerebral palsy (CP) has been identified as one of the most important and common causes of childhood disabilities worldwide and is often accompanied by multiple comorbidities. CP is defined as a group of disorders of the development of movement and posture, causing activity limitation that are attributed to non-progressive disturbances that occurred in the developing fetal or infant brain. The objective of our study was to describe main clinical pattern and motor impairments of our patients, and to evaluate the presence of risk factors and if there is a relation to the type of cerebral palsy. Methods Children with cerebral palsy were retrospectively enrolled over 2 years from the neurology outpatient clinics. Cerebral palsy risk factors and motor impairments were determined through caregiver interviews, review of medical records, and direct physical examination. Results One thousand children with cerebral palsy were enrolled. Subjects were 64.4% male, with a median age of 2.5 years. The risk factors for cerebral palsy in our study were antenatal (21%), natal and post-natal (30.5%), post-neonatal (17.1%), and unidentified (31.4%). Antenatal as CNS malformation (26.6%), maternal DM (17.6%), prolonged rupture of membrane (11.9%), maternal hemorrhage (10.4%), and pre-eclampsia (4.7%). Natal and post-natal as hypoxic ischemic encephalopathy (28.5%), infection (16.3%), hyperbilirubinemia (12.7%), cerebrovascular accidents (8.8%), meconium aspiration (6.2%), and intracranial hemorrhage. Post-neonatal as CNS infection (34.5%), cerebrovascular accidents (28.6%), sepsis (23.9%), and intracranial hemorrhage (8.7%). Conclusions Cerebral palsy has different etiologies and risk factors. Further studies are necessary to determine optimal preventative strategies in these patients.

Abstract Background Oral antimicrobial therapy for Enterobacteriales bloodstream infection (EB-BSI) is advantageous to reduce the risk of central line complications, cost of care, and length of stay. Fluoroquinolones (FQ) given their high bioavailability have been utilized as the standard for stepdown therapy (SDT) for EB-BSI. Given the recent increased warnings around FQ use including Clostridioides difficile infection (CDI) and the increasing FQ resistance alternative oral options for treatment are warranted. Recent literature has suggested beta-lactams (BLM) may be an option for EB-BSI. To enhance the antimicrobial stewardship goal of reducing FQ use, our team began recommending de-escalation to a BLM for EB-BSI and the objective of this study is to evaluate the outcomes of this approach. Methods This study was a retrospective chart review of patients with EB-BSI due to ceftriaxone sensitive monomicrobial E. coli, Klebsiella spp., or P. mirabilis who received a BLM or a FQ as SDT. Patients were excluded if < 18 years of age; pregnant; ANC < 1000 cells/µL; had endocarditis, a bone/joint, or a CNS infection; discharged to hospice or expired prior to discharge; anaphylactic BLM allergy; or prior kidney transplant. SDT was defined as a switch to a definitive oral antibiotic after empiric IV therapy. The primary outcome was clinical cure defined as completion of therapy without signs of infection (increase in WBC > 2000 cells/mL if WBC was ≥ 12,000 cells/mL, fever (>38°C), or change in antibiotic due to failure). Secondary outcomes included 30 day re-admission rates, reinfection rate defined as positive culture within 30 days of completion of therapy, antibiotic associated adverse events defined as side effects leading to discontinuation and/or CDI within 90 days from start of treatment. Results A total of 159 patients were included in the study (Figure 1). The BLM patients had a higher median age (78 vs 72, p=0.008), higher median PITT bacteremia score (2 vs 1, p=0.037), were less likely to be immunosuppressed (9% vs 25%, p=0.045), and had shorter median duration of therapy (13 vs 14, p=0.034). There was no difference in the primary or secondary outcomes (Table 2). Conclusion BLM may enhance stewardship efforts as a FQ sparing option for treatment of EB-BSI; however, prospective studies in this area are warranted.

IntroductionCutibacterium acnes is a Gram positive, anaerobic bacterium of low pathogenic potential that forms part of the normal cutaneous flora. Although most often identified as a contaminant in culture of microbiological specimens, it is commonly implicated in both postoperative wound and implantable device infection. Neurosurgical device infections secondary to C. acnes are well recognised and are likely secondary to bacterial contamination from the skin during surgery. Indolent infection characterised by delayed presentation of weeks to months following intervention is common. C. acnes infection involving the central nervous system (CNS) in the absence of previous neurosurgical intervention is rare, but has been described following dental or mastoid infections and following facial trauma. A further case series has reported de novo C. acnes CNS infection occurring in the absence of these recognised risk factors, but with clinical features of meningitis being common to all.Methods and resultsWe describe a unique case of primary C. acnes extra-dural collection in a previously well patient with no neurosurgical history presenting with sub-acute focal seizures and progressive focal leptomeningeal thickening on MRI.ConclusionC. acnes CNS infection can occur in the immunocompetent and in the absence of neurosurgical intervention.

The elderly comprise less than 13 percent of world population. Nonetheless, they represent nearly half of all hospitalized adults. Acute change in mental status from baseline is commonly seen among the elderly even when the main process does not involve the central nervous system. The term “geriatric syndrome” is used to capture those clinical conditions in older people that do not fit into discrete disease categories, including delirium, falls, frailty, dizziness, syncope, and urinary incontinence. Despite the growing number of elderly population, especially those who require hospitalization and the high burden of common infections accompanied by encephalopathy among them, there are several unresolved questions regarding the optimal management they deserve. The questions posed in this systematic review concern the need to rule out CNS infection in all elderly patients presented with fever and altered mental status in the routine management of febrile encephalopathy. In doing so, we sought to identify all potentially relevant articles using searches of web-based databases with no language restriction. Finally, we reviewed 93 research articles that were relevant to each part of our study. No prospective study was found to address how should AFE in the aged be optimally managed.

Abstract Background Pediatric central nervous system (CNS) infections are potentially life-threatening and may incur significant morbidity. Identifying a pathogen is important, both in terms of guiding therapeutic management, but also in characterizing prognosis. Usual care testing by culture and PCR is often unable to identify a pathogen. We examined the systematic application of metagenomic next-generation sequencing (mNGS) for detecting organisms and transcriptomic analysis of cerebrospinal fluid (CSF) in children with CNS infections. Methods We conducted a prospective multi-site study that aimed to enroll all children with a CSF pleocytosis and suspected CNS infection admitted to one of three tertiary pediatric hospitals during the study timeframe. After usual care testing had been performed, the remaining CSF was sent for mNGS and transcriptomic analysis. Results We screened 221 and enrolled 70 subjects over a 12-month recruitment period. A putative organism was isolated from CSF in 25 (35.7%) subjects by any diagnostic modality. mNGS of the CSF samples identified a pathogen in 20 (28.6%) subjects, which were also all identified by usual care testing. The median time to result was 38 hours. Conclusion Metagenomic sequencing of CSF has the potential to rapidly identify pathogens in children with CNS infections.

Cns Infection

Sepsis associated encephalopathy (SAE) is a common but poorly understood neurological complication of sepsis. It is characterized by diffuse brain dysfunction secondary to infection elsewhere in the body without overt CNS infection. The pathophysiology of SAE is complex and multifactorial including a number of intertwined mechanisms such as vascular damage, endothelial activation, breakdown of the blood brain barrier, altered brain signaling, brain inflammation, and apoptosis. Clinical presentation of SAE may range from mild symptoms such as malaise and concentration deficits to deep coma. The evaluation of cognitive dysfunction is made difficult by the absence of any specific investigations or biomarkers and the common use of sedation in critically ill patients. SAE thus remains diagnosis of exclusion which can only be made after ruling out other causes of altered mentation in a febrile, critically ill patient by appropriate investigations. In spite of high mortality rate, management of SAE is limited to treatment of the underlying infection and symptomatic treatment for delirium and seizures. It is important to be aware of this condition because SAE may present in early stages of sepsis, even before the diagnostic criteria for sepsis can be met. This review discusses the diagnostic approach to patients with SAE along with its epidemiology, pathophysiology, clinical presentation, and differential diagnosis.

Background: Risk factors for nosocomial infections and their impact on ICH outcomes are unclear. We hypothesized that factors present on admission are associated with developing infection, and patients who develop infections have worse outcomes. Methods: We determined prevalence of infections among patients in ERICH, a multicenter, triethnic case-control study of ICH. Exclusion criteria specific to this analysis were incomplete CT data and death/withdrawal of care <72 hours after admission. Patients with infection <two weeks before ICH were excluded from risk factor analyses, but included for outcomes assessments. We compared prevalence of risk factors for infections using chi-square and non-parametric tests, and performed multivariate logistic regression for risk of infection. Results: We enrolled 1397 individuals, 144 of whom died/had withdrawal of care within 72 hours and 210 with incomplete CT data, leaving 1043 patients. Nosocomial infections occurred in 300 patients (29%). Factors associated with presence of infections included ICH volume (13mL vs. 7mL, p <0.0001), GCS on admission (13 vs. 15, p <0.0001), WBC > 10 (42% vs. 32%), and higher CRP levels (4.9 vs. 1.8, p=0.01). Blacks had higher infection rates versus whites and Hispanics (33% vs. 27% and 24%, p=0.06). Procedural factors associated with infection included ventriculostomy, intrathecal-tPA, and intubation, while major neurosurgical procedures were associated with a 10-fold increase in CNS infection (all p <0.001). Infections were associated with bowel-bladder dysfunction, CHF/pulmonary edema, decubiti, DVT, dysphagia requiring PEG, and MI. Patients with infection were more likely to have DNR/DNI orders or to be dead at discharge (12.3% vs. 6.5%, p=0.0017). In a multivariate model for factors associated with infection, ICH volume, HIV history, intubation, CHF/pulmonary edema, and dysphagia requiring PEG were all associated with infection. Conclusion: There are identifiable risk factors associated with nosocomial infection after ICH, and infections are associated with mortality. Identification of patients at risk for infections may improve outcomes after ICH.

Acute Form

A review was made of the available literature on central nervous system (CNS) involvement in Chagas' disease. Thirty-one works concerning the acute nervous form and 17 others dealing with the chronic nervous form, all presenting neuropathologic studies, were critically analysed. Based on this analysis, an attempt was made to establish the possible natural history of CNS involvement in Chagas' disease. Among others, the following facts stand out: 1) the initial, acute phase of Trypanosoma cruzi infection is usually asymptomatic and subclinical; 2) only a small percentage of cases develop encephalitis in the acute phase of Chagas' disease; 3) the symptomatic acute forms accompanied by chagasic encephalitis are grave, with death ensuing in virtually all cases as a result of the brain lesions per se or of acute chagasic myocarditis, this being usually intense and always present; 4) individuals with the asymptomatic acute form and with the mild symptomatic acute form probably have no CNS infection or, in some cases, they may have discrete encephalitis in sparse foci. In the latter case, regression of the lesions may be total, or residual inflammatory nodules of relative insignificance may persist. Thus, no anatomical basis exists that might characterize the existence of a chronic nervous form of Chagas' disease; 5) reactivation of the CNS infection in the chronic form of Chagas' disease is uncommon and occurs only in immunosuppressed patients.
