Perianal disease is a particularly morbid phenotype of Crohn's disease, affecting up to one third of patients, with a significantly diminished quality of life. Conventional medical therapy and surgical interventions have limited efficacy. Medical…

Surgical training does not end at the conclusion of residency training. Expansions in medical technology and surgical technique have created a steep learning curve for the young attending surgeon. The emergence of intraoperative telementoring has…

Metastasis to the penis is an extremely rare entity. Malignant priapism is defined as a persistent, nonsexual erection that is refractory to pharmacologic treatment, corporal aspiration, and surgical shunts. Furthermore, it is typically a hallmark of…

In this report, the case of a 24-year-old Caucasian female with type 2 membranoproliferative glomerulonephritis status-post living donor kidney transplant managed on triple regimen immunosuppressive therapy who developed shingles is discussed. With…

Spontaneous renal hemorrhage is an uncommon entity with potentially serious consequences. We present a 68-year-old female with a three-day history of progressively worsening left-sided flank pain due to spontaneous left renal hemorrhage without a…

Antipsychotic medications are frequently prescribed to assisted living (AL) residents who have dementia, although there is a lack of information about the potential side effects and adverse events of these medications among this population.…

OBJECTIVE: Laser interstitial thermal therapy (LITT) provides a minimally invasive alternative to open brain surgery, making it a powerful neurosurgical tool especially in pediatric patients. This systematic review aimed to highlight the …

Highlights •Case Sequence of robotic prostatectomy was not associated with worse surgical outcomes including surgical margin rate.•Factors associated with increased rate of positive surgical margin include higher pre-operative PSA, higher percent…

Background: The Brain Injury Guidelines (BIG) provide a validated framework for categorizing patients with small intracranial haemorrhages (ICH) who could be managed by acute care surgery without neurosurgical consultation or repeat head computed…

An understanding of adult day service centers' (ADC) impacts on clients' health and well-being has been hampered by a lack of large-scale data. Standardizing data collection is critical to strengthening ADC programs, demonstrating their …

Despite good overall outcomes in most patients undergoing ileal pouch–anal anastomosis (IPAA), there is still hesitation about performing an IPAA in older patients due to the comorbidity burden and concern about incontinence. The aim of this work was…

Objective: To evaluate the experiences and preferences of ophthalmology residency applicants and program directors (PDs), with emphasis on the effect of COVID-19 as well as recent changes on the application process. Design: Cross-sectional, online…

Background: Spinal ventral epidural arteriovenous fistulas (EDAVFs) are rare and underdiagnosed entities and usually present with benign symptoms such as radiculopathy. To the best of our knowledge, EDAVFs presenting with massive vertebral body…

AIM: Despite good overall outcomes in most patients undergoing ileal pouch anal anastomosis (IPAA), there is still hesitation in performing an IPAA in older patients due to comorbidity burden and concern for incontinence. We aimed to identify…

Body composition is associated with risk of disease progression and treatment complications in a variety of conditions. Therefore, quantification of skeletal muscle mass and adipose tissues on Computed Tomography (CT) and/or Magnetic Resonance…

BACKGROUND CONTEXT: We developed the New England Spinal Metastasis Score (NESMS) as a simple, informative, scoring scheme that could be applied to both operative and non-operative patients. The performance of the NESMS to other legacy scoring…

BACKGROUND: To quantitatively evaluate the brain MRI morphological abnormalities in patients with cyclin-dependent kinase-like 5 deficiency disorder (CDD) on a group level and longitudinally. METHODS: We performed surface-based MRI analysis on …

Obesity is associated with inflammation and insulin resistance (IR), but the regulation of insulin sensitivity (IS) and connections between IS and inflammation remain unclear. We investigated the role of miR-467a-5p, a miRNA induced by…

The inferolateral triangle is a surgical skull base triangle used as a neurosurgical landmark. There are few reports of its measurements with little attention paid to anatomical variations. The inferolateral triangle was measured in ten adult human …

Background Abnormalities of right ventricular (RV) strain have been shown to occur prior to impairment of global right ventricular function, measured by global RV ejection fraction (RVEF) in patients with increased RV afterload, such as pulmonary…

Breech presentation complicates as many as 4% of all deliveries. External cephalic version (ECV) is a procedure that involves the external rotation of the fetus through the mother's abdomen from a breech position into a cephalic position. It provides…

Adult day centers (ADCs) are nonresidential settings that support the health and social needs of vulnerable older adults. Due to ADCs' congregate nature and participants' compromised health status, many ADCs have been forced to close during the…

This manuscript describes the abrupt pivot of VQI physician members away from standard clinical practice to a restrictive phase of emergent and urgent vascular procedures in response to the pandemic. The Society for Vascular Surgery Patient Safety…

In response to the pandemic, an abrupt pivot of VQI physician members away from standard clinical practice to a restrictive phase of emergent and urgent vascular procedures occurred. The Society for Vascular Surgery Patient Safety Organization …

OBJECTIVES: To determine whether current guidelines emphasizing antibiotic stewardship in pediatrics have been associated with reduced prevalence of antibiotic allergies in children severely affected by otitis media undergoing bilateral myringotomy…

PURPOSE: To assess for a positive results bias in recently published randomized controlled trials (RCTs) in the field of vitreoretinal disease.Methods: A bibliometric analysis was conducted examining RCTs published in the field of retina between…
