Pelvic Incidence as a Predictor of Proximal Junctional Failure in Patients Undergoing Anterior Column Realignment with Anterior Longitudinal Ligament Release to Restore Lordosis in Adult Spinal Deformity: A Retrospective Cohort Study.

Objective: To identify variables that may contribute to the development of proximal junctional failure (PJF) in patients with long lumbo-sacral and thoraco-lumbo-pelvic constructs undergoing anterior column realignment (ACR) with anterior longitudinal ligament release (ALLR).

Methods: Data of patients with adult spinal deformity who underwent ACR with ALLR at L3-4 were collected retrospectively from medical records and a prospectively maintained spine research database between 2016 and 2022.

Results: Eleven (41%) developed PJF at a mean of 24 ± 21 months from the index surgery.

Biochemical Markers of Early Renal Dysfunction in Patients with β-thalassemia Major: A Systematic Review and Meta-analysis.

Background: Early diagnosis of renal dysfunction in β-thalassemia major (β- TM) may help take specific measures to delay irreversible damage and renal failure. Therefore, the present meta-analysis aimed to compare biochemical markers of premature renal dysfunction between β-TM and healthy subjects and identify renal issues' prevalence in patients with β-TM.

Methods: We searched PubMed, Cumulative Index of Nursing and Allied Health Literature (CINAHL), Medline, Scopus, Web of Science, ScienceDirect, ProQuest, Google Scholar, and State Inpatient Databases (SIDs) without any language constraints for all relevant articles published up to April 2019.

Malignant Spinal Tumors.

Malignant spinal tumors constitute around 22% of all primary spinal tumors. The most common location of metastases to the spinal region is the extradural compartment. The molecular and genetic characterization of these tumors was the basis for the updated WHO classification of CNS tumors in 2016, where many CNS tumors are now diagnosed according to their genetic profile rather than relying solely on the histopathological appearance.

Vein of Galen Malformations in adults.

Objective: Vein of Galen Malformations (VoGM) are rare vascular malformations, typically seen in pediatric age groups. Even more rarely, VoGM's may be seen later in adulthood. In this case report and systematic review, we provide a thorough description of the current literature as well as provide a case example exploring the diagnosis, imaging, treatment, and management of VoGM in adults.

The Role of Oxidative Stress in the Progression of Secondary Brain Injury Following Germinal Matrix Hemorrhage.

Germinal matrix hemorrhage (GMH) can be a fatal condition responsible for the death of 1.7% of all neonates in the USA. The majority of GMH survivors develop long-term sequalae with debilitating comorbidities.

Predictive Value of K -67 Index in Evaluating Sporadic Vestibular Schwannoma Recurrence: Systematic Review and Meta-analysis.

 K -67 is often used as a proliferation index to evaluate how aggressive a tumor is and its likelihood of recurrence. Vestibular schwannomas (VS) are a unique benign pathology that lends itself well to evaluation with K -67 as a potential marker for disease recurrence or progression following surgical resection.  All English language studies of VSs and K -67 indices were screened.

Postoperative magnetic resonance imaging signal changes in middle cerebral peduncle after vestibular schwannoma surgery.

Background And Purpose: Preoperative compression of middle cerebellar peduncle (MCP) is often observed in vestibular schwannomas. Its re-expansion is expected after tumour resection, however, frequently its thickness remains unchanged or undergoes further atrophy. Similarly, increased MCP FLAIR signal is often observed and thought to be associated with intraoperative MCP injury.

Modern Appraisal of Patency and Complications in Cerebral Bypass Surgery: A Single Institution Experience.

Background: Cerebral bypass is a valuable surgical technique in well-selected patient populations. Updated clinical guidelines and improved surgical techniques warrant a contemporary reevaluation of the complications and patency to inform clinical practice and enhance postoperative patient care.

Objective: To assess the complication rates and postoperative graft patency for the 3 most common indications for bypass surgery: moyamoya disease, intracranial atherosclerosis, and intracranial aneurysms.

Improved Outcomes with Concurrent Instrumentation and Fusion of the Sacroiliac Joint in Patients with Long Lumbosacral Constructs.

Study Design: Retrospective Cohort Study.

Objective: Spinal fusion, specifically constructs connected to pelvic bones, has been consistently reported as a predisposing factor to sacroiliac joint (SIJ) pain. The aim of this study is to compare SIJ outcomes in patients with constructs to the pelvis following instrumentation vs instrumentation plus fusion of the SIJ.

Neuroendoscopic Transventricular Approach for Cystic Craniopharyngioma.

The literature is rich with many studies reporting different treatment modalities and approaches for cystic craniopharyngioma (CC), including microsurgery, neuroendoscopic transventricular approach, endoscopic transnasal surgery, stereotactic drainage, and Ommaya reservoir insertion. The goals of this manuscript are to report the successful treatment of an atypical case of CC using the neuroendoscopic transventricular approach (NTVA) as well as discuss the different surgical modalities for these tumors following a comprehensive review of the literature. Our patient is a nine-year-old female with a large CC who was managed using the NTVA.

Complex craniosynostosis in the context of Carpenter's syndrome.

Carpenter's syndrome or acrocephalopolysyndactyly type II is a rare genetic autosomal recessive disease, with an incidence estimated at 1 per 1 million births. Common findings of a brachydactyly, polysyndactyly, and a trefoil-like skull with extreme brachycephaly due to fusion of the bilateral coronal, sagittal and lambdoid sutures. We report a 12-month-old male who was referred to our care for evaluation of a craniofacial deformity-a trefoil-like skull, flattened and receding forehead, bulging of temporal bones, hypertelorism, exorbitism, and polysyndactyly in the upper and lower limbs and psychomotor delay.

Predicting neurosurgical clearance in the polytrauma patient with concomitant traumatic brain injury.

The goal of this study is to develop a model based on previously used prognostic predictors in traumatic brain injury (TBI) patients with polytrauma, which will facilitate the decision-making of whether to clear these patients for non-cranial surgery. Data of eligible patients was obtained from a trauma database at a Level I trauma and academic tertiary referral center in the United States. The number of days seen by the neurosurgical service prior to clearance, injury severity score (ISS), post-trauma day 0 (PTD 0) of Glasgow Coma Score (GCS), intracranial pressure (ICP) score and computed tomography (CT) score, as well as the changes in GCS, ICP score and CT score between PTD 0 and day of clearance were the variables used in developing the model.

Pediatric mild head trauma: is outpatient follow-up imaging necessary or beneficial?

Objective: Pediatric traumatic brain injury (TBI) is the leading cause of death among children and is a significant cause of morbidity. However, the majority of injuries are mild (Glasgow Coma Scale score 13-15) without any need for neurosurgical intervention, and clinically significant neurological decline rarely occurs. Although the question of repeat imaging within the first 24 hours has been discussed in the past, the yield of short-term follow-up imaging has never been thoroughly described.

Subarachnoid Hemorrhage and Internal Carotid Artery Dissection and Occlusion Following Self-Enucleation.

Self-enucleation is an uncommon type of major self-injury, which may lead to severe neurological deficits and life-threatening complications, such as subarachnoid hemorrhage (SAH) and internal carotid artery (ICA) dissection and occlusion. Our patient is a 53-year-old man with a history of bipolar disorder and schizophrenia who presented with SAH, intraventricular hemorrhage, ICA dissection and occlusion, and right cerebral infarct following self-enucleation. Despite a Glasgow Coma Score of 6 on initial presentation, he improved with conservative management.

Sacroiliac joint arthropathy in adult spinal deformity patients with long constructs to the pelvis.

Objective: Sacroiliac joint (SIJ) arthropathy is an increasingly recognized problem in adult spinal deformity patients undergoing long construct surgery. S2-alar-iliac (S2AI) screw instrumentation is thought to reduce morbidity from pelvic fixation in these patients. The goal of this study is to assess the overall incidence of SIJ arthropathy in patients with long constructs to the pelvis as well as compare SIJ outcomes of partially threaded (PT) versus fully threaded (FT) S2AI screws.

Transpalpebral transorbital neuroendoscopic (TONES) repair of orbital meningoencephalocele: a technical note.

Purpose: Intraorbital encephalocele (OMEC) is a rare entity in adults, usually secondary to an orbital pathology or prior trauma, in particular orbital roof fractures. Treatment of the OMEC is warranted to alleviate the pulsating exophthalmos and prevent potential visual decline. OMEC and orbital roof fractures have been predominantly treated via a craniotomy with a reconstruction of the orbital roof using various implants.

Spontaneous regression of multiple intracranial capillary hemangiomas in a newborn-long-term follow-up and literature review.

Background: Intracranial capillary hemangiomas (ICHs) have a natural history and behavior that is very different from intracranial cavernous malformations. The literature is not consistent as to the best management strategy for ICHs.

Case Description: Our patient is a 40-day-old male infant who presented with progressive increase in head circumference and multiple cutaneous capillary and ICHs.

Adolescent Disc Disease: Risk Factors and Treatment Success-Related Factors.

Objective: A paucity of literature is available discussing the associated risk factors, treatment options (including the use of minimally invasive surgery), and outcomes related to lumbar disc herniation (LDH) in children. We have discussed the risk factors for disc disease among pediatric patients and evaluated the efficacy of the minimally invasive approach.

Methods: A retrospective review of pediatric patients with lumbar disc disease who had undergone microdiscectomy at our institution from 2005 to 2016 was conducted.

Teflon versus Ivalon in Microvascular Decompression for Trigeminal Neuralgia: A 2-Center 10-Year Comparison.

Background: Trigeminal neuralgia features jolts of pain along the distribution of the trigeminal nerve. If patients fail conservative management, microvascular decompression (MVD) is typically the next step in treatment. MVD consists of implanting a separating material, often Teflon, between the nerve and compressive lesions.

Spontaneous Regression Followed by Rupture of an Untreated Brain Arteriovenous Malformation.

Background: Brain arteriovenous malformations (AVMs) are dynamic lesions. Unlike the recruitment of additional vessels and the growth of the nidus over time, which are well reported in the literature, spontaneous regression is much less frequent. Only a handful of cases reporting recanalization of spontaneously regressed AVMs have been published.

Management of Thoracic Disc Herniation Using the Mini-Open Retropleural Approach: Technique Illustration and Clinical Outcomes of 33 Patients From a Single Academic Center.

Background: Conventional surgical approaches used in the management of thoracic disc herniation (TDH) are associated with high morbidity. The development of minimally invasive and mini-open approaches has consistently improved patient outcomes.

Objective: To report our experience and outcomes of patients with symptomatic TDHs who underwent discectomy and partial corpectomy using the mini-open retropleural (MORP) approach as well as provide a detailed and illustrated technical description of the approach.

A glimpse into the history of description of the antiphospholipid syndrome.

Prior to 1983, several landmark reports prepared the stage for a detailed description of the Antiphospholipid (Hughes) syndrome (APS). Formerly depicted as lupus-like, APS exhibits a wide spectrum of symptoms that overlap with Sjogren's, Hashimoto, and other autoimmune diseases. In this review, we take a glimpse into the history of description of APS, discussing the events that led to its recognition as one of the most common autoimmune diseases and the enormous impact of that recognition in the rheumatology field.
