The Rowing Spine: A Review of Biomechanics, Injury, and Treatment.

OBJECTIVE: We aimed to describe spinal biomechanics and injury patterns in rowing. METHODS: In this systematic literature review, a Google and PubMed literature search was undertaken using keywords "rowing," "biomechanics," and "spine." RESULTS: Relevant articles were reviewed and synthesized to describe biomechanics, injury patterns, treatment options, and techniques for injury prevention. CONCLUSIONS: Rowing has increased in popularity throughout the United States. Up-to-date knowledge of rowing biomechanics and spinal injury patterns is necessary for prompt diagnosis and appropriate treatment of the injured rowing athlete.

Risk Factors for Blood Transfusions in Primary Anatomic and Reverse Total Shoulder Arthroplasty for Osteoarthritis.

Background: The purpose of this study was to determine risk factors for blood transfusion in primary anatomic and reverse total shoulder arthroplasty (TSA) performed for osteoarthritis. Methods: Patients who underwent anatomic or reverse TSA for a diagnosis of primary osteoarthritis were identified in a national surgical database from 2005 to 2018 by utilizing both CPT and ICD-9/ICD-10 codes. Univariate analysis was performed on the two transfused versus non-transfused cohorts to compare for differences in comorbidities and demographics. Independent risk factors for perioperative blood transfusions were identified via multivariate regression models. Results: 305 transfused and 18,124 nontransfused patients were identified. Female sex (p<0.001), age >85 years (p=0.001), insulin-dependent diabetes mellitus (p=0.001), dialysis dependence (p=0.001), acute renal failure (p=0.012), hematologic disorders (p=0.010), disseminated cancer (p<0.001), ASA ≥ 3 (p<0.001), and functional dependence (p=0.001) were shown to be independent risk factors for blood transfusions on multivariate logistic regression analysis. Conclusion: Several independent risk factors for blood transfusion following anatomic/reverse TSA for osteoarthritis were identified. Awareness of these risk factors can help surgeons and perioperative care teams to both identify and optimize high-risk patients to decrease both transfusion requirements and its associated complications in this patient population. Level of Evidence: III.

The history of neurosurgery at the University of Rochester.

The Department of Neurosurgery at the University of Rochester has a long legacy of excellent patient care and innovation in the neurosciences. The department's founder, Dr. William Van Wagenen, was a direct pupil of Harvey Cushing and the first president of the Harvey Cushing Society. His successor, Dr. Frank P. Smith, was also a leader in organized neurosurgery and helped to permanently memorialize his mentor with an endowed fellowship that today is one of the most prestigious training awards in neurosurgery. The first 2 chiefs are honored every year by the department with memorial invited lectureships in their names. The department is home to a thriving multidisciplinary research program that fulfills the lifelong vision of its founder, Dr. Van Wagenen.

September 2001: 51-year-old man with seizures since childhood.

The September 2001 COM. A 51 year old man with refractory seizures presented with a recent seizure while at work but no other neurologic deficit. Imaging studies demonstrated a solid and cystic lesion of the right temporal lobe. Microscopic and immunohistochemical studies demonstrated an atypical ganglioglioma due to the presence of neurofibrillary tangles within the neoplastic ganglion cell component. This is the fifth case reported in the literature. Neoplastic ganglion cells and neurofibrillary tangles are discussed both separately and as integral components of this rare tumor.
