Betel Nut Use And Hyperglycemia, Edward Nabrinsky, Badar Hasan, Talal Asif, Rebecca R. Pauly

Marshall Journal of Medicine

Betel nut chewing previously has not been common in North America, yet it is the fourth major source of addiction and abuse worldwide. Approximately 700 million individuals, or 10 % of the global population, chew beetle nut on regular basis. It is important for patient safety and improved quality to recognize its use in uncontrolled diabetes. Our case is of a 49 year-old Burmese female with PMH of DM2, HTN, and benign paroxysmal positional vertigo (BPPV) who presented with a complaint of dizziness. Patient denied alcohol or tobacco use, but reported a 20-year history of betel nut chewing (4-5 times/day). …

Bronchopleural Fistula Resolution With Endobronchial Valve Placement And Liberation From Mechanical Ventilation In Acute Respiratory Distress Syndrome: A Case Series, Haris Kalatoudis, Nikhil Meena, Fuad Zeid, Yousef Shweihat

Internal Medicine

Patients who have acute respiratory distress syndrome (ARDS) with persistent air leaks have worse outcomes. Endobronchial valves (EBV) are frequently deployed after pulmonary resection in noncritically ill patients to reduce and eliminate bronchopleural fistulas (BPFs) with persistent air leak (PAL). Information regarding EBV placement in mechanically ventilated patients with ARDS and high volume persistent air leaks is rare and limited to case reports. We describe three cases where EBV placement facilitated endotracheal extubation in patients with severe respiratory failure on prolonged mechanical ventilation with BPFs. In each case, EBV placement led to immediate resolution of PAL. We believe endobronchial valve …

Internal Medicine

Sarcoid like reaction is a well-known entity that occurs as a consequence to several malignancies or their therapies. Immunotherapy has gained a lot of interest in the past few years and has recently gained approval as first line therapy in multiple advanced stage malignancies. Pneumonitis has been described as complication of such therapy. Granulomatous inflammation has been only rarely reported subsequent to immunotherapy. We describe a case of granulomatous inflammation reactivation affecting the lungs in a patient previously exposed to Pembrolizumab and have evidence of a distant granulomatous infection. We discuss potential mechanisms of the inflammation and assert the importance …

Systematic Analysis Of Whole Exome Sequencing Determines Ret G691s Polymorphism As Germline Variant In Melanoma, Brent J. Smith Jr, Jennifer D. Hintzsche, Carol M. Amato, Aik-Choon Tan, Keith R. Wells, Allison J. Applegate, Rita T. Gonzalez, Jodie R. Barr, William A. Robinson

Marshall Journal of Medicine

Abstract

The RET proto-oncogene encodes a receptor tyrosine kinase that is activated by glial cell derived neutrotrophic factor (GDNF). Previous studies have found that a single nucleotide polymorphism (SNP), RETp (G691S), in the juxtamembrane domain enhances the signaling pathway and promotes tumor growth by GDNF in pancreatic and thyroid cancer in addition to melanoma. It is uncertain however whether this SNP is a germline variant or somatic mutation. A prior study reported that the RETp variant was a germline SNP in desmoplastic and non-desmoplastic melanomas. In the present study, we examined both melanoma tissue samples and matching peripheral blood DNA …

Hpv Vaccination Among Females With Mental And Physical Limitation, Melissa Rowe, Audra L. Pritt, Amanda J. Stratton, Jennie L. Yoost

Marshall Journal of Medicine

Introduction

Adolescent HPV vaccination rates lag behind other vaccinations, partly due to missed opportunities for vaccination and lack of provider recommendation. This study evaluated the rates of HPV vaccination among adolescents with physical and mental limitation and controls, and evaluated differences in parental knowledge and reasons for nonvaccination between groups.

Materials and Methods

A retrospective chart review was performed on female patients age 12-18 presenting to pediatric or gynecology clinics in 2012. Those subjects with a diagnosis of mental or physical limitation were classified as “affected”. HPV vaccination rates were compared between affected and control groups. Parents of affected subjects …

Angiosarcoma Of The Lower Extremity Presenting As Bilateral Pneumothoraces, Mark H. Cooper

Marshall Journal of Medicine

Abstract

Spontaneous pneumothorax usually presents as unilateral disease. Bilateral spontaneous pneumothoraces are less common and are more likely to be secondary than primary. We describe a case of bilateral spontaneous pneumothoraces that were resistant to conventional treatment, and found ultimately to be secondary to angiosarcoma of the lower extremity. A previously well 49 year old white female was referred to our institution in London with bilateral pneumothoraces. A left video assisted thoracoscopic procedure was undertaken, and the wedge resection of the lung specimen contained an area of metastatic tumor. Talc was placed into the left pleural cavity; talc was also …

Dislodging Anchored Diagnoses: An Unusual Presentation Of Acute Appendicitis, Talal Asif, Ravali Gummi, Zara Wadood, Kristy E. Steigerwalt, Rebecca R. Pauly

Marshall Journal of Medicine

Cognitive errors are the most common cause of diagnostic errors in the process of clinical decision making. Recently, there has been an immense focus on the new science of error prevention in health care. Anchored thinking or heuristics is a form of cognitive error that portrays shortcuts or abbreviated thinking in the light of diagnostic uncertainty. The risk is of comfort in a typical scenario and not being able to adapt to a new situation. Here we present an intriguing case of acute appendicitis in a patient who was initially admitted and treated for hypothermia and alcohol withdrawal. As the …

Cigarette Smoking And Cardio-Renal Events In Patients With Atherosclerotic Renal Artery Stenosis, Christopher A. Drummond, Pamela S. Brewster, Wencan He, Kaili Ren, Yanmei Xie, Katherine R. Tuttle, Steven T. Haller, Kenneth Jamerson, Lance D. Dworkin, Donald E. Cutlip, Timothy P. Murphy, Ralph B. D'Agostino Sr., William L. Henrich, Jiang Tian, Joseph I. Shapiro Md, Christopher J. Cooper

Biochemistry and Microbiology

Cigarette smoking causes cardiovascular disease and is associated with poor kidney function in individuals with diabetes mellitus and primary kidney diseases. However, the association of smoking on patients with atherosclerotic renal artery stenosis has not been studied. The current study utilized data from the Cardiovascular Outcomes in Renal Atherosclerotic Lesions (CORAL, NCT00081731) clinical trial to evaluate the effects of smoking on the risk of cardio-renal events and kidney function in this population. Baseline data showed that smokers (n = 277 out of 931) were significantly younger at enrollment than non-smokers (63.3±9.1 years vs 72.4±7.8 years; p<0.001). In addition, patients who smoke were also more likely to have bilateral renal artery stenoses and peripheral vascular disease (PVD). Longitudinal analysis showed that smokers experienced composite endpoint events (defined as first occurrence of: stroke; cardiovascular or renal death; myocardial infarction; hospitalization for congestive heart failure; permanent renal replacement; and progressive renal insufficiency defined as 30% reduction of GFR from baseline sustained for ≥ 60 days) at a substantially younger age compared to non-smokers (67.1±9.0 versus 76.1±7.9, p<0.001). Using linear regression and generalized linear modeling analysis controlled by age, sex, and ethnicity, smokers had significantly higher cystatin C levels (1.3±0.7 vs 1.2±0.9, p<0.01) whereas creatinine and estimated glomerular filtration rate (eGFR) were not different from non-smokers. From these data we conclude that smoking has a significant association with deleterious cardio-renal outcomes in patients with renovascular hypertension.

Prospect Of The Use Of Checkpoint Inhibitors In Hepatocellular Cancer Treatments, Ali Raufi Feb 2017

Prospect Of The Use Of Checkpoint Inhibitors In Hepatocellular Cancer Treatments, Ali Raufi

Internal Medicine

Hepatocellular cancer (HCC) is a very fatal disease due to limited therapeutic options as well as due to its association with underlying chronic liver disease in the majority of cases. The immune evasion in HCC signifies a major barrier to the delivery of effective immunotherapy. Sorafenib is the only Food and Drug Administration-approved drug available with an overall response rate of 2%–3% and overall survival of 2.8 months. Chemotherapy has not been used routinely because of the relative refractoriness of advanced HCC. The introduction of immune checkpoint inhibitors (cytotoxic T-lymphocyte antigen 4, programmed death 1, and programmed death-ligand 1) has …

Orthopaedic Surgeon Density In West Virginia, Franklin D. Shuler, Grant S. Buchanan, Zachary Sanford, Milad Modarresi, James Timothy Reagan, Kelly Scott, Chad Fisher, Ali Oliashirazi

Marshall Journal of Medicine

Abstract

West Virginia (WV) has many healthcare disparities and access barriers. For bone and joint disorders, WV has some of the highest rates of musculoskeletal problems, including the highest reported rate of adult arthritis in the nation (36.2%). We hypothesized that WV has one of the lowest Orthopaedic surgeon densities in the country, which can negatively impact the delivery of musculoskeletal care. Using the WV Board of Medicine practitioner databank, the Veterans Administration practitioner data, and national Orthopaedic surgeon census data, we demonstrated a considerably low Orthopaedic surgeon density in WV (7.71/100,000 population versus the national average of 8.51/100,000 population) …

The detrimental effects of cigarette use during pregnancy are well documented. Studies have shown that cigarette smoking while pregnant is associated with multiple adverse outcomes including: pre-term birth, placental abruption, placenta previa, fetal growth restriction, stillbirth, increased rate of birth defects, and increased risk of sudden infant death syndrome. Cotinine is the primary metabolite of nicotine and allows for measurement of active as well as passive exposure. Cotinine freely cross the placental barrier and maternal concentrations are closely correlated with newborn plasma levels. The aim of this study was to compare maternally reported rates of tobacco use to fetal umbilical …

Inferior Stemi Complicated By Retroperitoneal Hemorrhage Due To Ruptured Aaa, Farley B. Neasman Iii, Melissa D. Lester, Nepal C. Chowdhury

Marshall Journal of Medicine

When patients present with life threatening conditions, a rapid cost-benefit analysis prioritizes care and commits treatment to a certain course that, in the case of ST Elevation Myocardial Infarction (STEMI) treated with drug-eluting stents (DES), could be fatal if there is any deviation. Antiplatelet therapy is vital and secondary concerns (i.e. bleeding diatheses) may accept suboptimal outcomes – in rare cases, another life-threatening condition may be unmasked, the treatment for which runs directly counter to the first. We present a case of STEMI with high clot burden treated with multiple DES, complicated by retroperitoneal hemorrhage due to a ruptured abdominal …

Complete Esophageal Obstruction After Endoscopic Variceal Band Ligation In A Patient With A Sliding Hiatal Hernia, Munthir Mansour Md, Yousef Abdel-Aziz Md, Hesham Awadh, Nihar Shah Md, Akash Ajmera

Gastroenterology

Complete esophageal obstruction is a rare complication of endoscopic variceal banding, with only 6 cases in the English literature since the introduction of endoscopic variceal banding in 1986. We report a case of complete esophageal obstruction following esophageal banding due to entrapment of part of a sliding hiatal hernia. To our knowledge, our case is one of few with esophageal obstruction post-banding, and the first associated with a hiatal hernia. We recommend caution when performing esophageal banding on patients with a hiatal hernia.

Employing The Enzyme Cofactor Function Of Ascorbic Acid To Affect Oncogenic Pathways In Human Melanoma: Modulating Hypoxia Inducible Factor-1Α And Dna Demethylation To Reduce Malignant Potential, Adam Patrick Fischer Jan 2017

Employing The Enzyme Cofactor Function Of Ascorbic Acid To Affect Oncogenic Pathways In Human Melanoma: Modulating Hypoxia Inducible Factor-1Α And Dna Demethylation To Reduce Malignant Potential, Adam Patrick Fischer

Theses, Dissertations and Capstones

Dioxygenase enzymes such as the HIF hydroxylases (PHD1-3, FIH) and the Ten-eleven translocation (TET1-3) enzymes regulate the activity of the hypoxia inducible factor-1a (HIF1a) transcription factor and the DNA methylation status of cells, respectively. Aberrant accumulation and activation of HIF-1a can allow malignant cells to acquire attributes that promote progression, chemotherapy resistance, and survival, while aberrant hypermethylation of gene promoters can silence the expression of tumor suppressor genes essential to preventing tumorigenesis. Inadequate levels of intracellular ascorbic acid (AA), a necessary cofactor for optimal dioxygenase enzyme function, could potentiate these tumorigenic conditions. In fact, plasma levels …

The Influence On Morbidity And Mortality When Blood Products Are Transfused Using Conventional Coagulation Tests Versus Teg Or Rotem In Trauma Patients Perioperatively, Teresa Diana Kelley

Theses, Dissertations and Capstones

Abstract: Coagulopathy in trauma patients occurs due to tissue injury, hemodilution (dilution of hematocrit and clotting factors), infusion of hypo-coagulable blood products (e.g., packed red blood cells), acidosis, hypothermia, continued blood loss, and depletion of clotting factors. The onset of coagulopathy begins with the initial tissue injury and evolves rapidly. Many factors need consideration when determining resuscitative treatment for the trauma victim. These factors include the amount of time for extraction from the field, transport time to a trauma center, associated weather, and treatment provided in route. This study compared two clinical laboratory pathways (Conventional Coagulation test and Rotational Thromboelastometry …
