Abstract
Cell-free DNA (cfDNA) is increasingly recognized as a promising biomarker candidate for disease monitoring. However, its utility in neurodegenerative diseases, like amyotrophic lateral sclerosis (ALS), remains underexplored. Existing biomarker discovery approaches are tailored to a specific disease context or are too expensive to be clinically practical. Here, we address these challenges through a new approach combining advances in molecular and computational technologies. First, we develop statistical tools to select tissue-informative DNA methylation sites relevant to a disease process of interest. We then employ a capture protocol to select these sites and perform targeted methylation sequencing. Multi-modal information about the DNA methylation patterns are then utilized in machine learning algorithms trained to predict disease status and disease progression. We applied our method to two independent cohorts of ALS patients and controls (n=192). Overall, we found that the targeted sites accurately predicted ALS status and replicated between cohorts. Additionally, we identified epigenetic features associated with ALS phenotypes, including disease severity. These findings highlight the potential of cfDNA as a non-invasive biomarker for ALS.

Abstract
Computer-assisted design and computer-assisted modeling (CAD/CAM), virtual surgical planning (VSP) and augmented/virtual reality (AR/VR) aid our ability to plan and perform complex craniofacial procedures. This study seeks to define the role of the aforementioned techniques in the separation of craniopagus conjoined twins. Six teams were identified who had successfully performed craniopagus twin separation with the use of CAD/CAM, VSP and/or AR/VR. Surgeons involved in separating craniopagus twins have increasingly utilized tools such as CAD/CAM models, VSP and AR/VR to plan and execute successful separation, and these tools are associated with higher success rates than historical controls.

Abstract
OBJECTIVE Cerebral ventricular shunt failure is common and presents with symptoms that range from headaches to death. The combination of Diamox (acetazolamide), Decadron (dexamethasone), and Zantac (ranitidine) (DDZ) is used at our institution to medically stabilize pediatric patients presenting with symptomatic shunt failure before shunt revision. We describe our experience of this drug combination as a temporizing measure to decrease symptoms associated with shunt failure. METHODS We performed a single-center retrospective chart review of patients younger than 18 years with ventricular shunt failure who underwent a shunt revision between January 2015 to October 2017 and received DDZ before surgery. The outcome variables evaluated included pre-DDZ and post-DDZ clinical symptoms, pain scores, and vital signs. RESULTS There were 112 cases that received DDZ before shunt revision. The 4 most commonly reported symptoms were analyzed. Headache was observed in 42 cases pre-DDZ, and post-DDZ there was a 71% reduction in headache (P < 0.0001); emesis was reported pre-DDZ in 76 cases, and post-DDZ there was an 83% reduction (P < 0.0001); irritability was noted pre-DDZ in 30 cases, and post-DDZ there was a 77% reduction (P = 0.0003); lethargy pre-DDZ was observed in 60 cases, and post-DDZ 73% demonstrated improvement (P < 0.0001). Maximum pain scores significantly decreased post-DDZ (P < 0.0001). Heart rate, systolic, and diastolic blood pressures significantly decreased post-DDZ (P < 0.0001, P < 0.0001, P = 0.0002, respectively). CONCLUSIONS The combination of Decadron, Diamox, and Zantac is a novel treatment for ventricular shunt failure that may temporarily improve symptoms in patients awaiting shunt revision. Future studies could compare efficacy with other medical treatments.

Abstract
As the diagnosis of Spina Bifida (SB) is often made prenatally, SB-specific prenatal counseling is needed. It is essential to provide information about medical care and lifelong impact of this diagnosis, treatment options available to women carrying fetuses affected, and resources that will assist in the care of individuals with SB. This article outlines the SB Prenatal Counseling Guidelines from the 2018 Spina Bifida Association's Fourth Edition of the Guidelines for the Care of People with Spina Bifida and acknowledges that further research in SB prenatal counseling is warranted.

Abstract
BACKGROUND 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. METHODS 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. RESULTS 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. CONCLUSIONS 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.

Abstract
BACKGROUND Patients undergoing cranial expansion including spring-mediated cranioplasty (SMC) and cranial vault remodeling (CVR) receive costly and high acuity post-operative intensive care (ICU) given concerns over neurologic and hemodynamic vulnerability. The authors analyzed perioperative and post-operative events for patients presenting with sagittal craniosynostosis (CS) undergoing SMC and CVR in order to compare complication profiles. METHODS The authors performed a single center retrospective cohort study of patients undergoing SMC and CVR for the treatment of nonsyndromic, isolated sagittal CS from 2011 to 2018. Perioperative and post-operative factors were collected, focusing on hemodynamic instability and events necessitating ICU care. Mann-Whitney U and Fisher exact tests were used to compare data with significance defined as P < 0.05. RESULTS Among 106 patients, 65 (61%) underwent SMC and 41 (39%) CVR. All CVR patients received prophylactic whole blood transfusion at time of scalp incision. Acute blood loss anemia was the most common post-operative complication, prompting n = 6 (9.2%) and n = 7 (17.1%) blood transfusions in the SMC and CVR cohorts, respectively (P < 0.24). Hemodynamic instability requiring blood transfusion was rare, occurring post-operatively in n = 2 (3.1%) and n = 2 (4.9%) patients in the SMC and CVR cohorts, respectively (P < 0.64). Two patients in the CVR cohort exhibited new neurologic symptoms that self-resolved, compared to no patients in the SMC cohort (P < 0.15). CONCLUSION Despite differing degrees of operative invasiveness, post-operative hemodynamic and neurologic decompensation following CVR and SMC for isolated sagittal CS repair remains similarly rare. Indications necessitating post-operative intensive care are infrequent. Post-operative hemoglobin monitoring may enable early prediction for hemodynamic instability.

Abstract
Congenital hydrocephalus (CH), characterized by enlarged brain ventricles, is considered a disease of excessive cerebrospinal fluid (CSF) accumulation and thereby treated with neurosurgical CSF diversion with high morbidity and failure rates. The poor neurodevelopmental outcomes and persistence of ventriculomegaly in some post-surgical patients highlight our limited knowledge of disease mechanisms. Through whole-exome sequencing of 381 patients (232 trios) with sporadic, neurosurgically treated CH, we found that damaging de novo mutations account for >17% of cases, with five different genes exhibiting a significant de novo mutation burden. In all, rare, damaging mutations with large effect contributed to ~22% of sporadic CH cases. Multiple CH genes are key regulators of neural stem cell biology and converge in human transcriptional networks and cell types pertinent for fetal neuro-gliogenesis. These data implicate genetic disruption of early brain development, not impaired CSF dynamics, as the primary pathomechanism of a significant number of patients with sporadic CH.

Abstract
Congenital hydrocephalus (CH), featuring markedly enlarged brain ventricles, is thought to arise from failed cerebrospinal fluid (CSF) homeostasis and is treated with lifelong surgical CSF shunting with substantial morbidity. CH pathogenesis is poorly understood. Exome sequencing of 125 CH trios and 52 additional probands identified three genes with significant burden of rare damaging de novo or transmitted mutations: TRIM71 (p = 2.15 × 10-7), SMARCC1 (p = 8.15 × 10-10), and PTCH1 (p = 1.06 × 10-6). Additionally, two de novo duplications were identified at the SHH locus, encoding the PTCH1 ligand (p = 1.2 × 10-4). Together, these probands account for ∼10% of studied cases. Strikingly, all four genes are required for neural tube development and regulate ventricular zone neural stem cell fate. These results implicate impaired neurogenesis (rather than active CSF accumulation) in the pathogenesis of a subset of CH patients, with potential diagnostic, prognostic, and therapeutic ramifications.

Abstract
This paper is a preliminary communication of several years of research into the life and work of the Austrian psychoanalyst and anarchist Otto Gross (1877-1920). Although he played a pivotal role in the birth of modernity, acting as a significant influence upon psychiatry, psychoanalysis, ethics, sociology and literature, he has remained virtually unknown to this day. Following a biographical sketch and an overview of his main theoretical contributions, the impact of Gross' life and work on the development of analytical theory and practice is described. His relationship with some of the key figures in psychoanalysis is presented, with particular emphasis on his connections to Jung. The paper concludes with an account of relevant contemporary interest in his work: the founding of the International Otto Gross Society, the first edition of The Collected Works of Otto Gross on the Internet, and the 1st and 2nd International Otto Gross Congresses which took place in Berlin in 1999 and at the Burghölzli Clinic, Zürich, in October 2000.
