Bladder Distension As A Cause Of Abdominal Compartment Syndrome, Muhammad Yasir, Muhammad Qamarul Hoda, Tauseef Ahmed

Department of Anaesthesia

Abdominal compartment syndrome (ACS) is increasingly identified in critically ill patient and its harmful effects are well documented. The disparity among the pressure, volume in abdominal cavity and its contents, results in ACS. The actual incidence of ACS is not known. However, it has been observed predominantly in patients with severe blunt and penetrating abdominal trauma, ruptured abdominal aortic aneurysms, retro- and intra-peritoneal hemorrhage, pneumoperitoneum, neoplasm, pancreatitis, ascites and multiple bone fracture. We present a case of 40-year female who underwent emergency cesarean section and developed abdominal compartment syndrome due to urinary bladder distension secondary to blockade of urinary catheter …

A Practicality Analysis Pertaining To Minimally Invasive Robot-Assisted Urologic Surgery, Chase Cavayero

The Pegasus Review: UCF Undergraduate Research Journal

Minimally invasive robot-assisted surgery is a technological development that has changed the field of medicine in the past decade. The introduction of the da Vinci® by Intuitive Surgical Inc. has opened up many interesting options in several different fields. Specifically, the field of urology has seen increased utilization of the robotic technique due to the precision allowed by the technology. Although many perioperative and postoperative benefits have been documented within the literature pertaining to robotic surgery, some surgeons contend that the extra cost associated with the procedures is not practical. To this point the extra cost has not been prohibitive, …

Androgen deprivation therapy (ADT) is palliative and prostate cancer (CaP) recurs as lethal castration-recurrent/resistant CaP (CRPC). One mechanism that provides CaP resistance to ADT is primary backdoor androgen metabolism, which uses up to four 3α-oxidoreductases to convert 5α-androstane-3α,17β-diol (DIOL) to dihydrotestosterone (DHT). The goal was to determine whether inhibition of 3α-oxidoreductase activity decreased conversion of DIOL to DHT. Protein sequence analysis showed that the four 3α-oxidoreductases have identical catalytic amino acid residues. Mass spectrometry data showed combined treatment using catalytically inactive 3α-oxidoreductase mutants and the 5α-reductase inhibitor, dutasteride, decreased DHT levels in CaP cells better than dutasteride alone. Combined blockade …

Pedunculated And Obstructive Wilms' Tumor: A Rare Presentation In A 2 Year- T Old Male, Leor T. Arbel, Morris Jessop, Osama Al-Omar

Faculty & Staff Scholarship

Wilms' tumor manifesting as an obstructing ureteral mass is extremely rare. Herein, we report an unusual case in which a child presented with a clinical picture concerning for and suggestive of ureteropelvic junction ob- struction (UPJO), but was instead found to have an intrapelvic pedunculated Wilms' tumor with extension into the proximal ureter. We discuss the patient's diagnostic workup, radiographic, operative and pathologic findings, as well as important lessons learned from this unusual case.

Efficacy Of Multi-Detector Computed Tomography For The Diagnosis Of Medullary Sponge Kidney, G. S. Gaunay, R. G. Berkenblit, C. H. Tabib, J. R. Blitstein, M. Patel, D. M. Hoenig

Journal Articles

© 2018 S. Karger AG, Basel. Objective: To expand the diagnostic armamentarium for medullary sponge kidney (MSK), we evaluate the use of high-resolution multidetector computed tomography (MDCT) for MSK diagnosis and compare to the standard intravenous urography (IVU). Despite a significant prevalence amongst stone formers, diagnosis of this well described condition has declined. IVU, the gold standard in MSK diagnosis, has largely been replaced by CT, which has previously been shown unable to demonstrate signs of MSK. Methods and Materials: Patients with known history of MSK based on IVU underwent limited MDCT urogram. Control group patients, without MSK, also had …

Multiple Roles Of Aryloxide Leaving Groups In Enantioselective Annulations Employing Α,Β-Unsaturated Acyl Ammonium Catalysis, M. D. Greenhalgh, S. Qu, A. M. Slawin, A. D. Smith

Journal Articles

© 2018 The Royal Society of Chemistry. An isothiourea-catalysed Michael addition-annulation process using β-fluoroalkyl-substituted α,β-unsaturated aryl esters and a range of 2-acylbenzazoles is reported for the enantioselective synthesis of dihydropyranone and dihydropyridinone products bearing polyfluorinated stereocenters (29 examples, up to 98% yield, >99:1 er). The choice of aryl group of the aryl ester proved essential in determining reaction enantioselectivity and dihydropyranone:dihydropyridinone product selectivity. The aryloxide leaving group is shown to play a number of essential additional roles, operating (i) as a Brønsted base, circumventing the need for an auxiliary base; and (ii) as a Lewis base to catalyse the isomerisation …

Testosterone And The Adult Male, Alex Straftis

Calvert Undergraduate Research Awards

Abstract

In the last 15 years, prescription testosterone sales have increased almost threefold. Testosterone is a powerful hormone, which has both physiological and behavioral effects on the adult male. These effects vary over a man’s life course and social ecology. In a natural setting, testosterone reaches a peak during early adulthood, declines gradually over midlife, and has exponential drops after the age of 70. Increasing testosterone, through testosterone replacement therapy (TRT), past early adulthood, is an evolutionary novel circumstance for an adult male. To gauge these effects, and the motivations that initiated them, this study conducted a preliminary text analysis …

Measuring The Prevalence Of Intradialytic Hypotension In A Satellite Dialysis Clinic: Are We Too Complacent?, Ulrich Steinwandel, Nick Gibson, Mandy Towell-Barnard, Richard Parsons, James J. R. Rippey, Johan Rosman

Research outputs 2014 to 2021

Aims and objectives

To measure the prevalence of symptomatic (S‐IDH) and asymptomatic intradialytic hypotension (A‐IDH) or postdialysis overhydration in a satellite haemodialysis clinic in Western Australia.

Background

Intradialytic hypotension is one of the most common side effects of haemodialysis caused by ultrafiltration provoking a temporary volume depletion. The prevalence of asymptomatic hypotension during dialysis has been rarely reported, but is considered to have the same negative consequences as symptomatic hypotension on various end organs like the brain and the gastrointestinal tract.

Design

Observational study on a retrospective 3‐month period of nursing recorded fluid‐related adverse events.

Methods

Percutaneous Externally Assembled Laparoscopic (Peal) Donor Nephrectomy: A Cohort Pain Comparison, Tyler Miskin, Isaac Kelly, Matthew Pierce, Samuel Abourbih, Duane D. Baldwin

Loma Linda University Student Journal

Donor nephrectomies can be technically demanding. Donors also may not be fully psychologically prepared for their post-operative pain or cosmetic outcome. A novel Percutaneous Externally Assembled Laparoscopic (PEAL) paradigm was developed to decrease incisional pain and laparoscopic scars. The aim of this study is to compare the post-operative outcomes between donor nephrectomies performed with and without the PEAL instruments.

The Feasibility Of Percutaneous Externally Assembled Laparoscopic Nephrectomy: A New Surgical System, Benjamin West, Jerry Thomas, Mohamed Keheila, Nazih Khater, Samuel Abourbih, Salim Cheriyan, Matthew Pierce, Duane D. Baldwin, Jim Shen

Loma Linda University Student Journal

Laparoendoscopic single-site (LESS) nephrectomy provides excellent cosmetic outcomes, but is technically challenging due to loss of triangulation and increased instrument collision. A novel Percutaneous Externally Assembled Laparoscopic (PEAL) surgical system was developed to simplify minimally invasive surgery while providing a nearly scarless outcome. In this study, the feasibility of the PEAL system for nephrectomy was determined.
