Spectral Changes Caused By Radiofrequency Ablation Of Cardiac Tissue, Mohammed Aljishi, Huda Asfour, Luther Swift, Narine Muselimyan, Marco A. Mercader, Narine Sarvazyan
GW Research Days 2016 - 2020
New diagnostic catheters can be developed by delivering and acquiring light through a small fiberoptic bundle. This can provide a useful real time feedback guidance to observe tissue damage caused by thermal injury used to treat cardiac arrhythmias. Yet, little is known about the exact spectral changes caused by radiofrequency ablation (RFA) in different types of cardiac tissue. We hypothesized that the most sensitive optical ranges for characterizing thermal injury can be revealed by comparing spectral information from different areas of the heart before and after RF ablation. Freshly excised porcine hearts were used to acquire and analyze excitation emission …

Otolaryngology For Internal Medicine: Increasing Exposure To Otolaryngology Using Computer Assisted Instruction, Arielle Thal, Philip Zapanta
GW Research Days 2016 - 2020
It has been well identified in previous literature that there is a lack of otolaryngology teaching for general practitioners. There is not currently a standardized curriculum for otolaryngology in undergraduate medical education or during residency for those pursuing a general field such as Emergency Medicine, Internal Medicine, Pediatrics or Family Medicine. While the need for more exposure to otolaryngology within these fields has been well documented, as 25% of primary care complaints are otolaryngology related, little has been done to identify the best method for educational intervention. Important topics for inclusion in such a curriculum have been identified and methods …

GW Research Days 2016 - 2020
Chronic wounds that have failed to heal after 3 months of appropriate wound care affect approximately 6.5 million people in the US with a prevalence of 1% and costs estimated at $25 billion per year. Medical students currently receive limited wound care training, yet to effectively manage chronic wounds, providers must both understand the biology of healing, and also remain up-to-date with wound care guidelines published by the Agency for Healthcare Research and Quality (AHRQ). The purpose of this student-led project was to investigate medical students' knowledge and comfort with wound care guidelines.
Severity Of Pain Is Not Associated With Urgency Of Diagnosis In Ed Patients With Abdominal Pain, Ryan Brunetti, Caitlin David, Lorna Richards, Melissa J. Mccarthy, Andrew C. Meltzer
Severity Of Pain Is Not Associated With Urgency Of Diagnosis In Ed Patients With Abdominal Pain, Ryan Brunetti, Caitlin David, Lorna Richards, Melissa J. Mccarthy, Andrew C. Meltzer
GW Research Days 2016 - 2020
Background
Abdominal Pain is the most common cause of visits to US Emergency Departments (EDs) and the causes range from urgent to non-urgent diagnoses. Distinguishing urgent versus non-urgent causes of abdominal pain is done through the use of clinical exam, lab studies and diagnostic imaging such as CT scans. There are no validated clinical decision rules to assist physicians in discriminating urgent from non-urgent causes of abdominal pain or which patient needs a CT scan. There is controversy regarding the use of CT scans for patients with abdominal pain due to the increased cost, radiation exposure and length of stay. …

GW Research Days 2016 - 2020
Studies on the pathophysiology and comorbidities associated with alopecia areata (AA) are limited. The purpose of this study was to determine the prevalence of androgen excess in AA and its subtypes, in relation to demographics and comorbidities. Medical records of 1,587 Patchy AA, AT, AU, and ophiasis patients seen in the Department of Dermatology at the Cleveland Clinic Foundation in Ohio between 2005 and 2015 were reviewed. Out of this cohort, 226 patients met the inclusion criteria. There is evidence that patients with AA had significantly greater prevalence of polycystic ovary syndrome (PCOS) than the general population (p<0.001). Androgen excess was identified in 42.5% (n=96) of the 226 patients with AA or any subtype (p<0.001). The androgen excess group was significantly more likely to present with irregular menses, hirsutism, adult acne, PCOS, and/or ovarian cysts (p<0.001). This study was limited by being retrospective. Our study demonstrated that AA is associated with androgen excess.

GW Research Days 2016 - 2020
Myasthenia gravis (MG) is an autoimmune neuromuscular disorder caused by antibodies directed against proteins present at the post-synaptic surface of neuromuscular junction (NMJ). A characteristic pathology of patients with early onset MG is thymic hyperplasia with ectopic germinal centers (GC). However, mechanisms that trigger and maintain thymic hyperplasia are poorly characterized. Micro-RNAs (miRNA) are small, non-coding RNAs that are increasingly appreciated to be involved in the pathology of several autoimmune diseases. In order to determine the central mechanisms involved in the pathology, thymus samples from MG patients were assessed by histology and grouped based on appearance of GC compared to …

Perioperative Aspirin Recommendations In Children With Fenestrated Fontan Undergoing Adenotonsillectomy, Mariam Ashraf, Pamela A. Mudd, Jamie Mcelrath Schwartz, Karen Thompson
GW Research Days 2016 - 2020
Objective: Pediatric patients who have undergone the Fontan procedure are often on a long term aspirin regimen which can complicate perioperative management. In high risk procedures such as adenotonsillectomy, hemorrhage can be a significant complication and aspirin use may increase the risk. There is a need for evidence-based protocol on how to manage aspirin intake in the perioperative period for Fontan patients. We report the case of a patient with Fontan palliation who underwent adenotonsillectomy and presented with postoperative hemorrhage.
Methods: PubMed was searched for guidelines, case reports, and reviews on pediatric Fontan patients, adenotonsillectomy, and perioperative aspirin …

Department of Surgery Gibbon Society Historical Profiles
In the mid-19th century, the Vienna School of Anatomy was at the epicenter of the rapidly growing field of anatomy. One of the school’s most distinguished professors, Hungarian-born anatomist Emil Zuckerkandl was instrumental in transforming anatomy from a descriptive science to one of practical and clinical value. A prolific researcher interested in nearly all areas of morphology and most famously, the chromaffin system, Zuckerkandl’s discoveries from more than a century ago still provide a foundation for surgeons to this day.

An extensive literature links circadian irregularities and/or sleep abnormalities to mood disorders. Despite the strong genetic component underlying many mood disorders, however, previous genetic associations between circadian clock gene variants and major depressive disorder (MDD) have been weak. We applied a combined molecular/functional and genetic association approach to circadian gene polymorphisms in sex-stratified populations of control subjects and case subjects suffering from MDD. This approach identified significant sex-dependent associations of common variants of the circadian clock genes hClock, hPer3 and hNpas2 with major depression and demonstrated functional effects of these polymorphisms on the expression or activity of the hCLOCK …

School of Medicine Faculty Publications
Kaposi's Sarcoma-associated Herpesvirus (KSHV) is the etiologic agent of several malignancies, including Kaposi's Sarcoma (KS), which preferentially arise in immunocompromised patients such as HIV+ subpopulation and lack effective therapeutic options. Heme oxygenase-1 (HO-1) has been reported as an important regulator of endothelial cell cycle control, proliferation and angiogenesis. HO-1 has also been found to be highly expressed in KSHV-infected endothelial cells and oral AIDS-KS lesions. We previously demonstrate that the multifunctional glycoprotein CD147 is required for KSHV/LANA-induced endothelial cell invasiveness. During the identification of CD147 controlled downstream genes by microarray analysis, we found that the expression of HO-1 is significantly …

BACKGROUND: Fear acquisition and extinction are central constructs in the cognitive-behavioral model of obsessive-compulsive disorder (OCD), which underlies exposure-based cognitive-behavioral therapy (CBT). Youth with OCD may have impairments in fear acquisition and extinction that carry treatment implications. We examined these processes using a differential conditioning procedure.
METHODS: Forty-one youth (19 OCD, 22 community comparisons) completed a battery of clinical interviews, rating scales, and a differential conditioning task that included habituation, acquisition, and extinction phases. Skin conductance response (SCR) served as the primary dependent measure.
RESULTS: During habituation, no difference between groups was observed. During acquisition, differential fear conditioning was observed …

Department of Obstetrics & Gynaecology
Ovarian malignancy is a serious disease affecting women of all ages, more so above 50 years, and they are still difficult to treat, partly because no truly effective therapy has yet been developed although presentation is often vague and non-specific, the symptoms are definitely present. It is important to recognize the symptoms so far, there is no test yet available, which is truly specific and suitable for screening and early detection of epithelial ovarian carcinoma. So, it is concluded that for prognosis and patient survival, early detection and treatment is mandatory.

We examined the pharmacokinetic properties of vancomycin conjugated to a bone-targeting agent (BT) with high affinity for hydroxyapatite after systemic intravenous administration. The results confirm enhanced persistence of BT-vancomycin in plasma and enhanced accumulation in bone relative to vancomycin. This suggests that BT-vancomycin may be a potential carrier for the systemic targeted delivery of vancomycin in the treatment of bone infections, potentially reducing the reliance on surgical debridement to achieve the desired therapeutic outcome.

Section of Gastroenterology
Primary Hepatic Carcinoid Tumor (PHCT) represents an extremely rare clinical entity with only a few cases reported to date. These tumors are rarely associated with metastasis and surgical resection is usually curative. Herein, we report two cases of PHCT associated with poor outcomes due to late diagnosis. Both cases presented late with non-specific symptoms. One patient presented after a 2-week history of symptoms and the second case had a longstanding two years symptomatic interval during which he remained undiagnosed and not properly worked up. Both these cases were diagnosed with hepatic carcinoid tumor, which originates from neuroendocrine cells. Case 1 …

A Randomised Controlled Trial Comparing The Effect Of Adjuvant Intrathecal 2 Mg Midazolam To 20 Micrograms Fentanyl On Postoperative Pain For Patients Undergoing Lower Limb Orthopaedic Surgery Under Spinal Anaesthesia, Francis Codero, Vitalis Mung’Ayi, Sharif Thikra
Anaesthesiology, East Africa
Background: Intrathecal adjuvants are added to local anaesthetics to improve the quality of neuraxial blockade and prolong the duration of analgesia during spinal anaesthesia. Used intrathecally, fentanyl improves the quality of spinal blockade as compared to plain bupivacaine and confers a short duration of post-operative analgesia. Intrathecal midazolam as an adjuvant has been used and shown to improve the quality of spinal anaesthesia and prolong the duration of post-operative analgesia. No studies have been done comparing intrathecal fentanyl with bupivacaine and intrathecal 2 mg midazolam with bupivacaine.
Objective: To compare the effect of intrathecal 2mg midazolam to intrathecal 20 micrograms …
Role Of Slit2 In Reducing Complications After Surgical Brain Injury, Prativa Sherchan
Role Of Slit2 In Reducing Complications After Surgical Brain Injury, Prativa Sherchan
Loma Linda University Electronic Theses, Dissertations & Projects
Surgical brain injury (SBI) is the inadvertent injury to brain tissue at the perisurgical site which occurs due to neurosurgical maneuvers such as incision, retraction, and electrocoagulation that can result in post-operative complications. Blood brain barrier (BBB) disruption and neuroinflammation are major pathophysiological consequences after neurosurgical injury. Blood brain barrier dysfunction leads to increased influx of water and plasma proteins as well as peripheral immune cell infiltration into the brain parenchyma that further potentiates brain edema and worsens post-operative neurological function. Activated resident immune cells and infiltrated peripheral immune cells release inflammatory mediators and promote oxidative stress and cell death …

Objective: Extracorporeal membrane oxygenation (ECMO) in our institution resulted in near total mortality prior to the establishment of an algorithm-based program in July 2010. We hypothesized that an algorithm based ECMO program improves the outcome of patients with acute myocardial infarction complicated with cardiogenic shock.
Methods: Between March 2003 and July 2013, 29 patients underwent emergent catheterization for acute myocardial infarction due to left main or proximal left anterior descending artery occlusion complicated with cardiogenic shock (defined as systolic blood pressure < 90mmHg despite multiple inotropes, +- balloon pump, lactic acidosis). Of 29 patients, 15 patients were before July 2010 (Group 1, old program), 14 patients were after July 2010 (Group 2, new program).
Results: There were no significant differences in the baseline characteristics, including age, sex, coronary risk factors …

Evaluations Of Neurologists By Their Patients And Residents Are Inversely Correlated, Michael R. Dobbs, Jonathan H. Smith
Neurology Faculty Publications
Objective and Background: We hypothesized that evaluation scores for attending neurologists by patients and residents would parallel one another. Additionally, we hypothesized that provider productivity would be also be associated with performance evaluations by patients and residents. Methods: In a university neurology department, we collected individual Clinician and Group Consumer Assessment of Healthcare Providers and Systems patient satisfaction scores and standardized resident evaluation scores (n = 22 faculty members). We performed bivariate analysis of doctor–patient satisfaction versus resident evaluation scores. Results: Attending neurologists with higher patient satisfaction received lower resident evaluation scores (P < .05). There seem to be disproportionate neurologists with low evaluations not meeting clinical productivity targets. Conclusion: Finding a significant inverse correlation …
