Background and Purpose Anterior palatal reconstruction using vomer flaps has been described during primary cleft lip repair. In this procedure, the mucoperiosteal tissue of the vomer is elevated to reconstruct the nasal mucosa overlying the cleft of the hard palate. Here the authors, evaluate the efficacy of a technique in which a superiorly based...

Diabetic cheiroarthropathy (DCA) is a relatively uncommon and underdiagnosed complication of poorly controlled diabetes. It is caused by non-enzymatic glycation of collagen that ultimately leads to microvascular damage and polyarticular stiffness. If diagnosed early, optimal management of serum glucose levels may lessen joint stiffness and prevent...

Background In plastic surgery academia, research output is heavily used as a metric of accreditation, from assessing residency applicants to evaluating faculty for promotion. The h index, defined as an author's h papers with at least h citations, is commonly used as a measure of academic success. However, the index itself disfavors junior researche...

Background There is limited information about minority representation throughout the plastic and reconstructive surgery (PRS) pipeline. The aim of this study was to examine trends in representation among minorities at different stages of the PRS training pathway, starting with potential candidates in high school through practicing physicians. Meth...

Sinus pneumocele is a rare condition marked by pathologic expansion of a paranasal sinus with concomitant bone loss. Here, we describe the case of a 24-year-old male who first presented with a 2×3 cm bony projection of his right medial forehead. Exam and history were notably absent for any skin tethering, prior trauma, inflammation, or neurological...

OBJECTIVE Studies have demonstrated the benefits of diversity in neurosurgery. However, recruitment of minoritized groups within the neurosurgical workforce consistently lags other surgical specialties. While racial and gender demographics of neurosurgical residents are well documented, there has been minimal exploration into the multidimensional n...

Inherited retinal diseases (IRDs) are progressive degenerative diseases which cause gradual vision loss or complete blindness. As over 270 gene mutations have been identified in the underlying pathology of IRDs, gene therapy as a treatment modality has been an increasingly active realm of investigation. Currently, the most common vehicle of ocular...

INTRODUCTION Ultrasound (US) imaging is cheap, portable, and widely available. It has been used in multiple medical disciplines, both as a means of diagnosis and therapy. Developing US as a platform for spinal cord perfusion monitoring in patients with spinal cord injury (SCI) would provide a cheap, accessible, and real-time platform for managing s...

Background: Elevated systolic blood pressure (SBP) has been linked to pre-procedural rebleeding risk and poor outcome in patients with aneurysmal subarachnoid hemorrhage (aSAH). However, the relationship between blood pressure parameters including mean arterial pressure (MAP) with rebleeding both prior to and during aneurysm securement remains uncl...

Elijah Malik Persad-Paisley is the winner of the third annual Rising Black Scientists Award for a graduate/postdoctoral scholar in the life and health sciences. For this award, we asked emerging Black scientists to tell us about their scientific vision and goals, experiences that sparked their interest in science, how they want to contribute to a m...

Objective To accurately examine the trends in the racial and gender composition of medical students applying and matriculating to urology residency programs. Methods Reports on race/ethnicity and gender for medical school graduates, and urology residency applicants and matriculants were obtained for years 2010-2018. The proportions of individuals...

Background: Cerebral vasospasm (cVSP) is a common complication in aneurysmal subarachnoid hemorrhage (aSAH) and is associated with worse outcomes. However, clinical significance of asymptomatic cVSP is poorly understood. We sought to determine the association of asymptomatic cVSP with functional outcome and hospital length of stay (LOS). Methods:...

OBJECTIVE US allopathic medical schools have experienced improvements in racial and ethnic diversity among matriculants in the past decade. It is not clear, however, whether better representation of historically excluded racial and ethnic groups at medical school entry impacts subsequent stages of the medical training pipeline leading into a specif...

Background Delayed cerebral ischemia (DCI) and poor functional outcome are common complications in patients who suffer from aneurysmal subarachnoid hemorrhage (aSAH). It has been proposed that pre-admission beta-blocker therapy may lower cerebral vasospasm (cVSP) risk after aSAH; however, this association with other antihypertensives is unknown. We...

Cerebral vasospasm (cVSP) is a common complication in patients with aneurysmal subarachnoid hemorrhage (aSAH) and is associated with worse outcomes. However, clinical significance of asymptomatic cVSP remains poorly understood. We sought to determine the association between asymptomatic cVSP and hospital length of stay (LOS), duration of external v...

Objective Intraoperative computed tomography and navigation (iCT-Nav) is increasingly used to aid spinal instrumentation. We aimed to document the accuracy and revision rate of pedicle screw placement across many screws placed using iCT-Nav. We also assess patient-level factors predictive of high-grade pedicle breach. Methods Medical records of pa...

OBJECTIVE Spinal fusion surgery is increasingly common; however, pseudarthrosis remains a common complication affecting as much as 15% of some patient populations. Currently, no clear consensus on the best bone graft materials to use exists. Recent advances have led to the development of cell-infused cellular bone matrices (CBMs), which contain liv...
