Association Of Perioperative Factors With Lymph Node Positivity In Bladder Cancer Following Radical Cystectomy, Alyssa Laguerta, Kimberly Toumazos, Virgil Kevin Demario, Vaishnavi Patel, Balaji Reddy, Mark Quiring, Evan Jones, Young Son, Ronald Clearie, Thomas Mueller

Rowan-Virtua Research Day

Introduction and objectives: The treatment of bladder carcinoma relies on a multimodal approach, including chemotherapy, radical cystectomy, and lymph node dissection, but clear guidelines for the optimal strategy remain ambiguous. Radical cystectomy is complex, with high morbidity and mortality, yet limited research has focused on its short-term implications for lymph node-positive bladder cancer. This study aims to address these gaps by identifying perioperative factors linked to lymph node positivity and comparing outcomes between lymph node-positive and negative patients.

Methods: We conducted a retrospective analysis of 4382 bladder cancer patients who underwent radical cystectomy, collecting comprehensive clinical and surgical data. Clinical …

Ultrasonographic Appearance Of Suspected Zinner Syndrome, Wen Hao Luo, Jared Garfinkle, Jack Hennen, Robert Martin, Kathleen Deiling

Rowan-Virtua Research Day

Zinner syndrome (ZS) is a rare congenital condition characterized by the triad of unilateral renal agenesis, ipsilateral seminal vesicle cyst, and ipsilateral ejaculatory duct obstruction. ZS is suspected to be caused by the malformation of the mesonephric duct during embryogenesis. The incomplete migration of the ureteric bud results in ipsilateral renal agenesis and ejaculatory duct obstruction. The remaining gonad develops with inadequate seminal fluid drainage, leading to the formation of seminal vesicle cysts. ZS is often asymptomatic, leading to challenges in diagnosis, particularly in adolescents. Symptoms can include pain, dysuria, pollakisuria, perineal pain, epididymitis, and pain after ejaculation. Imaging plays …

Hydralazine-Induced Vasculitis Resulting In Large Pleural Effusion And Progressive Renal Dysfunction, Michael A. Acevedo, Hammad Choudhry

Rowan-Virtua Research Day

Hydralazine is a vasodilator commonly used to treat high blood pressure. Even with the safety profile of Hydralazine, it is necessary to know that it may lead to Hydralazine-Induced Vasculitis. Here, we discuss how this rare side effect can present in an 80-year-old female with a past medical history of hypertension who presented to the emergency department with complaints of progressive shortness of breath on exertion and while lying supine. Further evaluation revealed a large right-sided pleural effusion with consolidation at the right lower lobe. The patient’s dyspnea worsened, and the surgical team placed a chest tube. The patient also …

Impact Of Fluid Composition On Mortality And Kidney Injury In Sepsis: A Literature Review, Kush C. Patel, Simran Gandhi, Harmann Singh, Abdullah Noory, Akash M. Patel

Rowan-Virtua Research Day

Background

Fluid resuscitation is a cornerstone of early sepsis management. While normal saline (NS) has been widely used, emerging evidence suggests that balanced crystalloids such as lactated Ringer’s and Plasma-Lyte may offer improved renal outcomes and reduced mortality by avoiding hyperchloremic metabolic acidosis.

Hypothesis

In adult patients with sepsis, initial resuscitation with balanced crystalloids reduces mortality and the incidence of acute kidney injury (AKI) compared to normal saline.

Methods

A literature review was conducted using PubMed and MEDLINE databases focusing on randomized controlled trials and meta-analyses published from 2010–2024. Key studies included the SMART, SALT-ED, BaSICS, and PLUS trials. The …

A Systematic Review On Cinacalcet’S Effect In Reducing Pth Serum Levels In Peritoneal Dialysis Patients, Akhil Gumidyala, Youssef Daoud, Mark Hanna, Han Jie Liu, Rikita Doshi

Rowan-Virtua Research Day

Background: Patients with Chronic Kidney Disease (CKD) have low calcium levels. Low blood calcium triggers the parathyroid gland to constantly secrete parathyroid hormone (PTH) in an attempt to raise blood calcium levels back to normal. One way PTH tries to do this is by removing calcium from bone. Chronically high PTH levels leads to increased bone resorption and increases the risk for bone fractures and mortality risk. This phenomenon is called secondary hyperparathyroidism (SHPT). Calcimimetics, like cinacalcet (sensipar), act similarly to calcium by binding allosterically to Calcium-Sensing Receptors (CaSR) on the parathyroid gland, thereby reducing PTH levels. The effect of …

He noted that he took a supplement which he purchased over the internet called Epimedium, also known as Horny Goat Weed, for the purpose of improving his mood and sense of energy and reducing his sense of anxiety. He noted that he started this supplement one month prior to ED presentation, coincident with the first episodes of muscle cramps. In the ED, he had elevations of his CK and creatinine and required hospital …

A Rare Case Of Diffuse Alveolar Hemorrhage In The Setting Of Iga Nephropathy, Vasculitis And Atypical Hemolytic Uremic Syndrome In A Previously Healthy Young Adult, Karl Schlicht, Nancy Kaura

Rowan-Virtua Research Day

IgA Nephropathy, also known as Berger disease, can precipitate acute renal failure in patients. IgA Nephropathy (IgAN) is deposition of protein from IgA into the renal tissue with subsequent renal dysfunction. IgA vasculitis (IgAV) is another condition where similarly the protein of IgA is deposited into the vessels. There are some cases of co-existing atypical hemolytic uremic syndrome (aHUS) with IgAN. However, rare combinations seen with all three IgAN, IgAV, and aHUS without any pre-existing conditions nor medical history. Patients that develop any one of these conditions are looking at life long changes with hemodialysis (HD) and organ transplants being …

Unveiling The Impact Of Phosphate On Skeletal Muscle Dysfunction In Chronic Kidney Disease, Hiram Garcia, Sowmya Duddu, Erik Hinojosa, Model Zerfu, Nathaniel L. Alvarez, Mohammad Razzaque, Alex Zuo

Research Colloquium

Background: Chronic Kidney Disease (CKD) is characterized by progressive decline in renal function that ultimately culminates in the inability of the kidneys to effectively maintain homeostasis. The kidneys are a key regulator of phosphate, with other organs assisting in regulation including the skeletal system. In CKD, reduced kidney function leads to hyperphosphatemia. While its impact on the skeletal system is moderately studied, its effects on skeletal muscle are less reviewed. In our literature review, we aim to describe the effects of phosphate in the context of patients who have CKD while providing clinical context for this deserving population. We describe …

Renal Mass Imaging Modalities: Does Body Mass Index (Bmi) Matter?, Young Son, Mark E Quiring, Raeann M Dalton, Brian Thomas, Noah Davidson, Dayna Devincentz, Collin Payne, Sahil H Parikh, Benjamin A Fink, Thomas Mueller, Gordon Brown

Rowan-Virtua School of Osteopathic Medicine Departmental Research

PURPOSE: Accurate measurement of renal mass size is crucial in the management of renal cancer. With the burdensome cost of imaging yet its need for management, a better understanding of the variability among patients when determining mass size remains of urgent importance. Current guidelines on optimal imaging are limited, especially with respect to body mass index (BMI). The aim of this study is to discern which modalities accurately measure renal mass size and whether BMI influences such accuracy.

METHODS: A multi-institutional chart review was performed for adult patients undergoing partial or radical nephrectomy between 2018 and 2021, with 236 patients …

The loss of contact inhibition is a key step during carcinogenesis. The Hippo-Yes-associated protein (Hippo/YAP) pathway is an important regulator of cell growth in a cell density-dependent manner. However, how Hippo signaling senses cell density in this context remains elusive. Here, we report that high cell density induced the phosphorylation of spectrin α chain, nonerythrocytic 1 (SPTAN1), a plasma membrane-stabilizing protein, to recruit NUMB endocytic adaptor protein isoforms 1 and 2 (NUMB1/2), which further sequestered microtubule affinity-regulating kinases (MARKs) in the plasma membrane and rendered them inaccessible for phosphorylation and inhibition of the Hippo kinases sterile 20-like kinases MST1 and …

Faculty, Staff and Student Publications

Clear cell carcinomas of Müllerian origin have a strong female predominance and only extremely rarely will arise within the kidney, presumably due to ectopic Müllerian embryogenesis. Herein, we report a unique case of metastatic Müllerian type clear cell carcinoma in a 37-year-old patient who had previously received a transplanted kidney from his father at age 11 (due to severe bilateral vesicoureteral reflux) and remained on chronic immunosuppression. The tumor was highly aggressive and demonstrated somatic mutations in NF2 and SETD2. Imaging of the transplanted kidney did not reveal any clear evidence of malignancy. However, targeted multigene sequencing and short tandem …

Hepatitis A Virus And Hepatitis E Virus As Food- And Waterborne Pathogens—Transmission Routes And Methods For Detection In Food, Katalin Nemes, Sofia Persson, Magnus Simonsson

Faculty, Staff and Student Publications

Foodborne viruses are an important threat to food safety and public health. Globally, there are approximately 5 million cases of acute viral hepatitis due to hepatitis A virus (HAV) and hepatitis E virus (HEV) every year. HAV is responsible for numerous food-related viral outbreaks worldwide, while HEV is an emerging pathogen with a global health burden. The reported HEV cases in Europe have increased tenfold in the last 20 years due to its zoonotic transmission through the consumption of infected meat or meat products. HEV is considered the most common cause of acute viral hepatitis worldwide currently. This review focuses …

Brash Syndrome Case Report And Brief Review, Kelly Schuitema

Rowan-Virtua Research Day

BRASH syndrome is an acronym that stands for bradycardia, renal failure, AV node blocker, shock and hyperkalemia. The syndrome is precipitated by synergism from AV nodal blocking agents and hyperkalemia. The combination of the AV nodal blockade and renal failure leads to a cycle of severe bradycardia and hyperkalemia. We will discuss a case of BRASH syndrome with a 68 year old female who presented with generalized weakness and was found to be hypotensive, bradycardia, in acute renal failure with hyperkalemia likely related to metoprolol and amlodipine use.

The Lawnmower And The Pediatric Lower Extremity: A Catastrophic Combination, Alvaro Tamayo-Gutierrez, Hassan N Ibrahim

Faculty, Staff and Student Publications

Heart failure can lead to renal impairment, an interaction now termed "cardiorenal syndrome." The prevalent physiological explanation for the renal impairment that accompanies heart failure centers around the forward failure hypothesis, which emphasizes the role of left ventricular dysfunction in causing edema, and the backward failure hypothesis, which singles out venous congestion as the dominant mechanism of edema and reduced glomerular filtration rate. In this review, we provide an appraisal on venous congestion, an extremely important contributor that has received little attention. We also summarize the pharmacology of loop diuretics, explain current understanding of diuretic resistance, and address controversies regarding …

Digoxin Toxicity And Acute Renal Failure In A 75 Year-Old Female, Daniel Zaayenga, Andrew Caravello, Nicholas Tomasello

Rowan-Virtua Research Day

Digoxin toxicity can present with varying manifestations. While pathognomonic symptoms such as xanthopsia (object appearing yellow) are a board favorite it is not a required finding and is in fact not seen with most patients. Rather digoxin toxicity presents with more non-specific symptoms such as GI distress (anorexia, N/V) neurological distress (lethargy, fatigue, delirium, confusion, disorientation, weakness. EKG findings are varied and include premature ventricular contractions, bradycardia, atrial tachyarrhythmias with AV block, ventricular bigeminy, junctional rhythms, various degrees of AV nodal blockade, ventricular tachycardia, and ventricular fibrillation. Although rarely seen, digoxin is one of the only causes of bidirectional ventricular …

Case Study Of Metformin-Induced Lactic Acidosis, Kajel Patel, Kishan B. Patel

Rowan-Virtua Research Day

Metformin induced lactic acidosis is when high levels of metformin cause dangerously high levels of lactic acid. Here is a case report of a 72-year-old female who came in for nausea, vomiting, and diarrhea found to have a high suspicion for metformin induced lactic acidosis. She stabilized in the emergency department, nephrology and ICU was contacted, and she went for emergent dialysis. For many patients the prognosis of metformin induced lactic acidosis is poor. This patient was made comfort care by her family.

Incidental Finding Of Unusually Large Renal Cyst During Point Of Care Ultrasound, David Ho, Jeffrey Gardecki

Rowan-Virtua Research Day

Renal cysts are common, and their frequency and size increase as patients age. Renal cysts are derived primarily from tubules and can occur anywhere between Bowman’s capsule to the renal papilla. The cysts are composed of abnormally differentiated epithelial cells encapsulating a cavity of fluid. These abnormally differentiated cells are due to defects in the structure and function of cilia, the structures responsible for detecting urine flow as well as the epithelial composition of the epithelial architecture and repair. According to Campbell Urology, there are three processes in which renal cysts increase in their size – proliferation of epithelial cells …

Long-Term Lithium Use In The Younger Population: Do The Benefits Outweigh The Risks? - A Case Report, Seema Shekar, Alexander Garcia, Rachel Shmuts

Rowan-Virtua Research Day

For decades lithium has been the mainstay treatment for bipolar disorder. While its side effect profile is extensive and varied its most notable adverse effect, and one most feared by treating clinicians, is nephrotoxicity/ end-stage renal disease (ESRD). While the link between long-term lithium use and ESRD has been accepted by the medical community at large for many years, more recent scientific studies call the association into question. In fact, newer studies on the association between Li use and ESRD have shown a negative/inconclusive correlation. Despite this controversy the consensus still remains that ESRD secondary to long-term Li use is …

Kidney Disease After Heart And Lung Transplantation, Carlos M Zapata, Hassan N Ibrahim

Faculty, Staff and Student Publications

Chronic kidney disease (CKD) is not only common after lung and heart transplantation but also is associated with increased morbidity and mortality due to multiple pre-, peri- and post-transplant factors. While the exact incidence of CKD in this population is not well-defined, it seems to have gradually increased over the years as older recipients are more frequently considered. The increasing success of the procedure and expanding transplant candidate pool has allowed many with comorbid conditions to receive a transplant, which was considered prohibitive in the past. This review presents risk factors that have been linked to CKD as well as …

Chronic Renal Failure, But Why? A Case Report., Palak Patel, Michael Rothberg

Rowan-Virtua Research Day

Renal failure, both acute and chronic, can present from many different etiologies and if diagnosed with diabetes mellitus, it is commonly assumed to be due to diabetic nephropathy. Monoclonal gammopathy of renal significance (MGRS) is a disorder that combines monoclonal gammopathy of undetermined significance with end stage renal disease. Monoclonal immunoglobulins are secreted by B or plasma cells leading to deposition in the kidney causing end organ damage. Several different subtypes fall under this category of renal diseases including, but not limited to, amyloidosis, C3 glomeruopathy, and light chain proximal tubulopathy, or better known as Fanconi syndrome1. Fanconi syndrome, which …

A Case Of Atraumatic Posterior Thigh Compartment Syndrome, Nailah Mubin, Brian Katt

Rowan-Virtua Research Day

Compartment syndrome(CS) occurs when intra-compartmental pressures exceeds to a point where arterial, venous and lymphatic circulation of local tissues, muscles and nerves is compromised. CS is most common after a traumatic injury and usually occurs in the leg or forearm and less commonly in the thigh. Thigh compartment syndrome is rare due to its larger size and more compliant borders. We present a case of nontraumatic compartment syndrome in the posterior thigh associated with rhabdomyolysis and a sciatic nerve palsy which then required emergent fasciotomy. The patient's course was further complicated by acute renal failure due to the rhabdomyolysis and …
