Flexor Tenosynovitis After Bite By Sugar Glider, Dominick Siconolfi, James Espinosa, Alan Lucerna, Russell Mordecai

Rowan-Virtua Research Day

Flexor tenosynovitis is one of the few orthopedic emergencies, often first identified in the emergency department. Pyogenic flexor tenosynovitis is an infection of the flexor tendon sheath of a finger causing local inflammation and tissue destruction. The pathognomonic symptoms of flexor tenosynovitis are known as Kanavel’s signs, a constellation of symptoms that include: pain with passive extension of the finger, tenderness over the flexor tendon sheath, fusiform swelling of the affected finger, and the finger held in passive flexion. The most common cause of flexor tenosynovitis is penetrating trauma into the flexion tendon sheath. Our case involves a 59-year-old male …

Spontaneous Conus Medullary Infarction In The Absence Of Cardiovascular Risk Factors, Bavica Gummadi, Jaffer Ahmed, Swarna Rajagopalan

Spinal cord infarction (SCI) is rare and most often occurs in individuals with predisposing cardiovascular risk factors and traumatic injuries

As there are no distinct diagnostic criteria for SCI, diagnosis is difficult in patients presenting without predisposing factors and is often mistaken for transverse myelitis.

Delay in early diagnosis contributes to the high case fatality rate of SCI.

This case highlights the importance of including SCI in the differential of a patient with acute paraparesis even in the absence of co-existing risk factors.

Phyllodes Tumor Containing Invasive Ductal Carcinoma: A Rare Case Description & Review Of Literature, Kathryn Eckert, John Ground, Alyssa Imperatore, Victoria Tiedemann, Linda Szczurek

Rowan-Virtua Research Day

Phyllodes tumors are uncommon, often benign, malignancies of the breast and account for approximately 0.5% of all breast malignancies. These tumors were first described in 1838 by Johannes Muller as cystosarcoma phyllodes and were later more aptly renamed phyllodes tumors (as they were neither cystic nor sarcomatous).(1) As a mixed connective tissue and epithelial tumor, these behave similar to benign fibroadenomas, though their growth is much more rapid and they tend to occur in older patients.(2) Hallmarked by their large size at presentation, these tumors average between 4 and 7 cm at the time of diagnosis. The only known risk …

Long-Term Impacts Of Acute Stressor Exposure On Locus Coeruleus Function And Anxiety-Like Behavior In Rats, Olga Borodovitsyna

Graduate School of Biomedical Sciences Theses and Dissertations

Stress is a physiological state characterized by behavioral arousal that occurs during exposure to harmful or threatening stimuli, and usually facilitates an adaptive behavioral response. The persistence of stress sometimes causes it to become maladaptive, potentially contributing to disease development, including physiological complications with altered neuroendocrine signaling and impaired function of organ systems, and psychological conditions including depression and anxiety. Anxiety disorders in particular are associated with a history of stress and are the most common class of mental disorders, with a lifetime prevalence of 33.7% in the general population. The locus coeruleus (LC) is a major node in the …

A High-Throughput Approach To Characterizing Arv1 On The Regulation Of Lipid Homeostasis Uncovers A Novel Interaction With Epidermal Growth Factor Receptor, Nicholas Anthony Wachowski

Graduate School of Biomedical Sciences Theses and Dissertations

Acyl-CoA cholesterol acyl transferase related enzyme-2 required for viability 1 (ARV1) was first recognized in Saccharomyces cerevisiae in a study done in 2000 by Tinkelenberg et al. In yeast, the deletion of ARV1 results in numerous defects including abnormal sterol trafficking [1], the reduction of sphingolipid metabolism [2], synthesis of glycosylphosphatidylinositol (GPI) anchor [3], ER stress [4], and hypersensitivity of fatty acids leading to lipoapoptosis [5]. Arv1 germline deletion in mice displayed a lean phenotype with increased energy [6]. In humans, ARV1 mutations lead to epileptic encephalopathy [7].
