Colon Cancer Metastasis To Spermatic Cord Presenting As An Inguinal Hernia, Jessica G. Laenger, Eamon Ff Rooney, Patrick F. Dial, Candie T. Le, Sanda A. Tan

HCA Healthcare Journal of Medicine

Introduction

Inguinal hernias are very common. Their pathology and treatment are typically strait forward. Metastatic cancer can sometimes present as an inguinal hernia, but this presentation is often local metastasis.

Case Presentation

Herein we describe the case of a 68-year-old man who presented with a 2-month history of an inguinal hernia. Intraoperatively, the hernia sac was found to contain a mass attached to the spermatic cord, which was later determined to be a metastatic lesion from a locally advanced proximal transverse colon adenocarcinoma.

Conclusion

A spermatic cord mass can be a rare presentation of colon cancer metastasis. Colon cancer should …

Cross-Contamination Of Crispr Guides And Other Unrelated Nucleotide Sequences Among Commercial Oligonucleotides, Hiroshi Arakawa, Hiromi Miura, Rolen M. Quadros, Masato Ohtsuka, Channabasavaiah B. Gurumurthy

Journal Articles: Genetics, Cell Biology & Anatomy

Custom oligonucleotides (oligos) are widely used reagents in biomedical research. Some common applications of oligos include polymerase chain reaction (PCR), sequencing, hybridization, microarray, and library construction. The reliability of oligos in such applications depends on their purity and specificity. Here, we report that commercially available oligos are frequently contaminated with nonspecific sequences (i.e. other unrelated oligonucleotides). Most of the oligos that we designed to amplify clustered regularly interspersed palindromic repeats (CRISPR) guide sequences contained nonspecific CRISPR guides. These contaminants were detected in research-grade oligos procured from eight commercial oligo-suppliers located in three different geographic regions of the world. Deep sequencing …

Anterior Cruciate Ligament Hybrid Remnant Preservation Reconstruction Demonstrates Similar Outcomes As Traditional Reconstruction After 6 Months: A Randomized Control Trial, Joshua P. Castle, Eleftherios L. Halkias, Brittaney Pratt, Ashley Frei, Matthew A. Gasparro, Vasilios Moutzouros

Medical Student Research Symposium

Background

The anterior cruciate ligament (ACL) is often debrided during reconstruction (ACLR) to improve visualization. However, remnant ACL tissue contains nerve fibers and including remnant tissue in ACLR could provide benefit. Therefore, a technique was developed that preserves the tibial remnant and incorporates it into ACLR: Hybrid Remnant Preservation Reconstruction (HRPR) ACLR. This study compares HRPR-ACLR to traditional reconstruction by comparing patient reported outcomes and complications.

Methods

Patients presenting to one surgeon's clinic with an ACL injury are screened. Exclusion criteria are patient age<14 years, multi-ligament injury, chronic tears, and revision ACLR. Patients are consented and randomized to HRPR or traditional ACLR. Demographics, patient-reported outcomes, range of motion (ROM) and complications were collected.

Results

Thirty-three patients were included, 20 HRPR and 13 controls. No demographic differences were noted. PROMIS-PF, …

Six-Month Report Assessing The Feasibility And Effectiveness Of Amniotic Membrane Injections In Patients With Short, Anterior, Urethral Strictures, Nicholas Pryde, Jack Vernocke, Aron Liaw, Michael Sessine, Nivedita Dhar

Medical Student Research Symposium

Introduction: Urethral stricture treatment has high recurrence rates and adjunct injectable agents have been explored. Amniotic membranes (AM) promote apoptosis of pro-inflammatory cells, prevent differentiation of pro-fibrotic cells, and decrease scar formation. These tissues generated interest in reconstructive urethral surgery. Thus, we performed urethral dilation combined with micronized AM injection in urethral scar tissue for treatment of urethral stricture.

Materials and Methods: Adult males with strictures ≤12Fr in diameter and ≤2 cm in length, International Prostate Symptom Score (IPSS) ≥11 and maximum flowrate <15 ml/s. Reconstituted 100mg micronized AM was injected at the time of urethral dilation. Primary study end point was anatomical success (≥14Fr by cystoscopy) at 6 months. Secondary end points were questionnaires, flow rate, and post void residual. Outcomes assessed at baseline, 5 days, 14 days, 3 months, and 6 months post-injection. Safety was analyzed.

Results: Ten men, mean age of 52 ± 15 years, were included. There were 7 patients with …


Piriformis Syndrome With A Variant Presentation, Roberto Chuapoco, Ryan E. Linford 2024 Touro University Nevada

Piriformis Syndrome With A Variant Presentation, Roberto Chuapoco, Ryan E. Linford

Annual Research Symposium

Piriformis syndrome has long been a diagnostic quandary due to its tendency to present as other nerve-related conditions. Piriformis syndrome is commonly caused by entrapment of the sciatic nerve as it travels through the greater sciatic foramen due to hypertrophy of the piriformis muscle. However, its constellation of symptoms, including radiating pain down the thigh, can easily be mistaken for lumbosacral radiculopathy. This case report aims to address the misdiagnosis of piriformis syndrome which has prolonged pain for many patients and increased the cost of medical care. It demonstrates a 76-year-old female with a confounding presentation of piriformis syndrome: buttock …

Adolescent alcohol use is a strong predictor for the subsequent development of alcohol use disorders later in life. Additionally, adolescence is a critical period for the onset of affective disorders, which can contribute to problematic drinking behaviours and relapse, particularly in females. Previous studies from our laboratory have shown that exposure to adolescent intermittent ethanol (AIE) vapour alters glutamatergic transmission in the bed nucleus of the stria terminalis (BNST) and, when combined with adult stress, elicits sex-specific changes in glutamatergic plasticity and negative affect-like behaviours in mice. Building on these findings, the current work investigated whether BNST stimulation could substitute …

Myocarditis is one of the major causes of heart failure in children and young adults and can lead to dilated cardiomyopathy. Lymphocytic myocarditis could result from autoreactive CD4+ and CD8+ T cells, but defining antigen specificity in disease pathogenesis is challenging. To address this issue, we generated T cell receptor (TCR) transgenic (Tg) C57BL/6J mice specific to cardiac myosin heavy chain (Myhc)-α 334-352 and found that Myhc-α-specific TCRs were expressed in both CD4+ and CD8+ T cells. To investigate if the phenotype is more pronounced in a myocarditis-susceptible genetic background, we backcrossed with A/J mice. At …

Understanding The Effects Of Hormone Treatments On The Transgender Singer: A Pedagogical Study And Voice Studio Guide, Erin M. Hannon

Theses and Dissertations--Music

Transitioning from one gender to another can be an arduous and emotionally charged experience, accompanied by many physical and mental transformations. The journey of self-discovery and vocal explorations is both unique and deeply personal. Modifications that emerge in an individual's vocal characteristics have a profound influence on their capacity to communicate and express themselves.

Transgender vocal students and professional singers must navigate the delicate balance between their vocal and gender identities while considering the possible risks of Gender Affirming Hormone Therapy. Though these therapies may significantly alter one's appearance and overall well-being, they are also capable of causing notable declines …


Quality Improvement Of X-Ray Imaging For Unspecified Chronic Knee Pain And Suspected Knee Osteoarthritis In The Primary Care Setting, Ty E. Bever 2024 The Robert Larner, M.D. College of Medicine at The University of Vermont

Quality Improvement Of X-Ray Imaging For Unspecified Chronic Knee Pain And Suspected Knee Osteoarthritis In The Primary Care Setting, Ty E. Bever

Family Medicine Clerkship Student Projects

Although a comprehensive history and physical exam are the mainstays of initial evaluation, plain X-rays are clinically indicated for chronic knee pain of greater than 6 weeks duration and acute traumatic pain in patients who meet specific evidence-based criteria, according to the American Academy of Family Physicians (AAFP). However, there remains significant variation in what radiographic protocols are used in clinical practice, specifically in terms of what radiographic views are ordered and whether the imaging is performed with the patient weight-bearing (WB) or non-weight-bearing (NWB). In fact, several studies have shown that non-weight-bearing knee radiographs are frequently ordered by general …

Mild traumatic brain injury (mTBI) accounts for 70-90% of all TBI cases. Lipid metabolites have important roles in plasma membrane biogenesis, function, and cell signaling. As TBI can compromise plasma membrane integrity and alter brain cell function, we sought to identify circulating phospholipid alterations after mTBI, and determine if these changes were associated with clinical outcomes. Patients with mTBI (Glasgow Coma Score [GCS] ≥13 and loss of consciousness <30 >min) were recruited. A total of 84 mTBI subjects were enrolled after admission to a level I trauma center, with the majority having evidence of traumatic intracranial hemorrhage on brain computed tomography …

BACKGROUND: Transgenic (Tg) mice are widely used in biomedical research, and they are typically generated by injecting transgenic DNA cassettes into pronuclei of one-cell stage zygotes. Such animals often show unreliable expression of the transgenic DNA, one of the major reasons for which is random insertion of the transgenes. We previously developed a method called "pronuclear injection-based targeted transgenesis" (PITT), in which DNA constructs are directed to insert at pre-designated genomic loci. PITT was achieved by pre-installing so called landing pad sequences (such as heterotypic LoxP sites or attP sites) to create seed mice and then injecting Cre recombinase or …

Unlike the majority of sauropsids, which breathe primarily through costal and abdominal muscle contractions, extant crocodilians have evolved the hepatic piston pump, a unique additional ventilatory mechanism powered by the diaphragmaticus muscle. This muscle originates from the bony pelvis, wrapping around the abdominal viscera, extending cranially to the liver. The liver then attaches to the caudal margin of the lungs, resulting in a sub-fusiform morphology for the entire ‘‘pulmo-hepatic-diaphragmatic’’ structure. When the diaphragmaticus muscle contracts during inspiration, the liver is pulled caudally, lowering pressure in the thoracolumbar cavity, and inflating the lungs. It has been established that the hepatic piston …

Enhanced Presynaptic Mitochondrial Energy Production Is Required For Memory Formation, Erica L Underwood, John B Redell, Kimberly N Hood, Mark E Maynard, Michael Hylin, M Neal Waxham, Jing Zhao, Anthony N Moore, Pramod K Dash

Journal Articles

Some of the prominent features of long-term memory formation include protein synthesis, gene expression, enhanced neurotransmitter release, increased excitability, and formation of new synapses. As these processes are critically dependent on mitochondrial function, we hypothesized that increased mitochondrial respiration and dynamics would play a prominent role in memory formation. To address this possibility, we measured mitochondrial oxygen consumption (OCR) in hippocampal tissue punches from trained and untrained animals. Our results show that context fear training significantly increased basal, ATP synthesis-linked, and maximal OCR in the Shaffer collateral-CA1 synaptic region, but not in the CA1 cell body layer. These changes were …


Median Arcuate Ligament Syndrome: A Rare Cause Of Abdominal Pain That Is Difficult To Identify, Mark E. Eskander, Matthew Thrall, Joel P. Thompson 2023 Lake Erie College of Osteopathic Medicine

Median Arcuate Ligament Syndrome: A Rare Cause Of Abdominal Pain That Is Difficult To Identify, Mark E. Eskander, Matthew Thrall, Joel P. Thompson

Advances in Clinical Medical Research and Healthcare Delivery

Median arcuate ligament syndrome (MALS) is a rare disease that occurs when the celiac artery is compressed by the median arcuate ligament. Patients with MALS typically present with non-specific symptoms that overlap with more common diseases. As a result, patients may undergo extensive workup and unnecessary treatments before being properly diagnosed with MALS. In this case we present a 23-year-old female with chronic postprandial abdominal pain that persisted despite undergoing a cholecystectomy. This case highlights the symptoms and imaging findings needed to diagnose MALS and thus prevent unnecessary surgical interventions.
