Approaching Quantum-Limited Electrometry In The Single-Photon Regime, Sisira Kanhirathingal

Dartmouth College Ph.D Dissertations

Mesoscopic quantum systems currently serve as essential building blocks in many quantum information and metrology devices. This thesis investigates the potential of quantum-limited detection in a mesoscopic electrometer named the cavity-embedded Cooper pair transistor (cCPT). As one application, this charge detector can act as the basis for an optomechanical system in the single-photon strong coupling regime. The realization of this scheme would entail near quantum-limited, ultra-sensitive electrometry at the single-photon level, the feasibility of which is studied at length in this thesis.

On the one hand, we approach this question using a fundamental, first-principles study, where an operator scattering model …

While polygenic risk scores (PRSs) enable early identification of genetic risk for chronic obstructive pulmonary disease (COPD), predictive performance is limited when the discovery and target populations are not well matched. Hypothesizing that the biological mechanisms of disease are shared across ancestry groups, we introduce a PrediXcan-derived polygenic transcriptome risk score (PTRS) to improve cross-ethnic portability of risk prediction. We constructed the PTRS using summary statistics from application of PrediXcan on large-scale GWASs of lung function (forced expiratory volume in 1 s [FEV1] and its ratio to forced vital capacity [FEV1/FVC]) in the UK Biobank. We examined prediction performance and …

A Case Report Of Suspected Choledocholithiasis 20 Years After Cholecystectomy, Maleeha Memon, Dhara Rana, Chandni Patel, Christine Leroy, Bijal Sheth

Rowan-Virtua Research Day

Gallstones are a common prevalence in western societies where approximately 15% of Americans have gallstones. The mainstay treatment for symptomatic cholelithiasis is laparoscopic cholecystectomy. It is estimated approximately 650,000 to 700,000 cholecystectomies are performed every year. Most patients feel relief after a laparoscopic cholecystectomy, but a small number of patients experience post cholecystectomy syndrome, which presents as biliary colic pain. Although the pathophysiology of the post cholecystectomy syndrome is unclear, one theory proposes that it is due to the alteration in bile flow after the removal of the gallbladder, which serves as a reservoir for bile. This bile is thought …

A Case Of Intracranial Empyema After Bacterial Sinusitis, Eric Doane, Bhumi Shah, Robert Belfer

Rowan-Virtua Research Day

Acute sinusitis in the pediatric population is a common presentation in the emergency department. Most cases are viral and can be managed conservatively and will resolve spontaneously in 7-10 days. Even in cases of bacterial sinusitis, patients can typically be discharged with oral antibiotics and close follow up with the pediatrician.

There is however a small subset of patients who will develop a rare lethal complication, an intracranial empyema. While the incidence in the developed world has decreased as antibiotics become more available, it is still estimated to occur in up to 5% of severe cases requiring hospitalization (1) . …

A Case Of Acute Disseminated Encephalomyelitis In An Adult Male With Bipolar Disorder, Jinisha Patwa, Tracey Harris

Rowan-Virtua Research Day

Acute disseminated encephalomyelitis (ADEM) is a rare demyelinating disease characterized by inflammation of the brain and spinal cord. The rapidly progressive inflammation in the central nervous system is known to occur in response to a prior infection or immunization.

The clinical signs of ADEM may manifest up to 60 days post illness or vaccination. Some develop encephalopathy and neurologic symptoms which include confusion, psychosis, and tetraparesis. Paresthesia of the limbs and muscular atrophy indicate a worse prognosis and higher risk of relapse as opposed to those with only CNS involvement. A predominantly psychiatric presentation is also possible.

Risk factors include …

With the new development of the SARS-CoV vaccine and the majority of the population receiving this vaccine, it is important to recognize some of the rare side effects associated with it.

VITT is a rare complication of the COVID vaccine

Diagnostic criteria: COVID vaccine 4-24 days prior to symptom onset, any venous or arterial thrombosis, thrombocytopenia < 150, positive PF4 HIT ELISA, markedly elevated D-dimer >4x ULN.

Vaccine Induced Thrombosis with Thrombocytopenia is a potentially life-threatening diagnosis that must be recognized and treated correctly to prevent poor outcomes.

A Review Of The Effectiveness Of Osteopathic Manipulative Medicine At Alleviating Pregnancy-Related Pain, Alexandria Lomanno, Olivia Choi, Danielle Cooley

Rowan-Virtua Research Day

Globally, more than a quarter of pregnant patients experience low back pain (LBP) during pregnancy with additional complaints of pelvic girdle pain (PGP) and other somatic dysfunctions. Though the standard of care for LBP in pregnancy is often analgesics, concerns about potential side effects that may cause lasting harm to the fetus may preclude pregnant patients from taking pain medications. Osteopathic Manipulative Medicine (OMM) is a nonpharmacologic treatment option that is routinely used for LBP in non-pregnant patients. Given the low risk of adverse effects, OMM may prove to be beneficial for pregnant patients suffering from LBP or PGP.

Rowan-Virtua Research Day

Ashwagandha is a popular Ayurvedic herb that is derived from the extracts of the roots of Withania somnifera, an evergreen shrub endemic to India and Southeast Asia. It is generally utilized as a tonic to increase one’s energy and reduce stress levels. Often referred to as “Indian ginseng”, it provides neuroprotective and anti-inflammatory properties that address stress, pain, and fatigue. Additionally, it may assist in dealing with rashes, diabetes, and arthritis. It has also been shown to counteract the effects of aging. Though these properties have not been shown in prospective studies, it has become a popular product among western …

Alternate Site Pacing And The Impact On Intracellular Calcium Handling During The Post-Extrasystolic Cardiac Cycle, Kent Ozcan, Lawrence Mulligan

Rowan-Virtua Research Day

Objective: Previous work has shown that alternate site (RV apex) results in myocardial dysfunction. With the development of tools to place endocardial pacing leads in locations that create physiological pacing activation, we sought to evaluate how ventricular trans-septal or left ventricular apical placement pacing differs from right atrial pacing. We will evaluate how these chronic pacing modes impact the PR and RF at baseline, 0, and 16 weeks in the canine heart.

Methods: Quantitative analysis will be performed on previously generated data. The data set includes pacing of 15 dogs total (8 with trans-septal leads & 7 with left ventricular …

Purpose: Establish if early adequate pain control is protective in the development of chronic pain syndromes.

Data collected via survey to patients being treated for chronic pain at the Neuromuscular Institute at RowanSOM

Data (small n) suggests patients with chronic pain have poorly controlled pain levels at the time of the acute event.

Anticipate with increased sample size will see a correlation between chronic pain prevalence and severity and perceived early adequate analgesia following the acute event.

Assessing The Impact Of The Covid-19 Pandemic On Adolescent Mental Health, Vanessa Pizutelli, Yanil Morales, Christina Copeland, Archana Salek

Rowan-Virtua Research Day

Adolescence is a crucial period in which adverse childhood experiences, social relationships, and habits can influence mental wellbeing. According to the CDC, the onset of mental illness is 14.5 years old, which is why it is imperative that individuals with mental health conditions receive early intervention. Since the start of the Covid-19 pandemic, research has shown a dramatic decline in adolescent mental health. Specifically in New Jersey, it has been reported that individuals ages 18-23 have the highest levels of stress and depressive symptoms since the start of the pandemic. In light of these findings, it is vital that more …

Bells Palsy: A Late Complication Of Sars-Cov-2 Infection, Rohan Umrani, Sameer Akhtar, Sean Coulson, Brian Thomas, Yvette Wang

Rowan-Virtua Research Day

A 60 year old male with a PMH of SARS-CoV-2, OSA and primary hypogonadism presented with a chief complaint of left sided facial numbness and weakness.

Bells Palsy is commonly caused by HSV, VZV, Lyme disease and less commonly ischemia or local compression. It presents with facial paralysis and loss of taste in anterior 2/3 of tongue.

In the absence of definitive Lyme serologies despite history of tick bite, it is likely that this patient had Bell’s Palsy as a late manifestation of COVID-19.

Bilateral Teratomas In Pediatric Patient With Unilateral Ovarian Torsion, David Ho, Maya Borowczak, Archana Verma

Rowan-Virtua Research Day

Ovarian torsion is a surgical emergency found in both pediatric and adult populations. It involves the full or partial rotation of the vessels that supply the ovary, resulting in ischemia. In this report, we present the case of a pediatric patient arriving to the Pediatric Emergency Department (PED) for evaluation of right lower quadrant (RLQ) abdominal pain, who was found to have an ovarian torsion. In this particular case, the patient’s ovarian torsion was due to a teratoma, and imaging would later identify an additional smaller teratoma on the contralateral side. This case shows the importance of considering ovarian pathologies …

A Rare Case Of Acute Appendicitis In A 21-Year-Old Male With Midsternal Chest Pain, Muhammad Noman, James Espinosa, Alan Lucerna, Andrew Caravello

Rowan-Virtua Research Day

Acute appendicitis is inflammation of the vestigial vermiform appendix. It is one of the leading causes of emergency department visits due to abdominal pain. The vermiform appendix is located at the base of cecum. The attachment does not change; however the tip may migrate to the retrocecal, subcecal, preileal, postileal and pelvic positions. Considering these normal anatomical positions, the pain presentation may vary in patients.

Even though this patient presented with midsternal chest pain, which was suspicious for GERD, it was crucial to perform a thorough head-to-toe exam to discover incidental findings that the patient did not report. In this …

A Case Of Akinetic Mutism In Patient With Unilateral Anterior Communicating Artery Stroke, David Ho, Or Shachar, James Espinosa, Alan Lucerna, James Lee

Rowan-Virtua Research Day

Akinetic mutism, a rare neurological condition involving sensory, motor, language, behavior, and emotional changes, mimicking locked-in syndrome, should be considered in acute stroke patients presenting with speech deficits. This condition, although debilitating initially, does have prospects for recovery. In this case report, we present the case of a patient presenting to the ER for altered mental status, found to be in DKA, NSTEMI, suspected narcotic overdose, and unilateral acute ischemic stroke of the left anterior communicating artery (ACA), who was found to have Akinetic Mutism. In stroke patients presenting with aphasia and dysarthria, it is worth considering akinetic mutism in …

Case Report: Glioblastoma Tumor Presenting With Mild Changes In Memory, Samuel Thalathoti, Nicholas Palladino, James Espinosa, Alan Lucerna

Rowan-Virtua Research Day

We report a case of a 66-year-old female who presented to the ED with generalized headache and mild confusion, who was diagnosed with high-grade glial neoplasm. The differential diagnosis of headache is vast, but without red flags or symptoms is generally from a benign cause and easily treatable. However, even in the context of a normal neurologic physical exam, symptoms such as confusion, forgetfulness, and behavioral changes should merit imaging in the workup. Glioblastoma is the most common brain tumor, accounting for 47.7% of all cases, with an incidence of 3.21 per 100,000 population. Median age of diagnosis is 64 …

Case Report: A Patient With Gait Dysfunction With Acute Inflammatory Demyelinating Polyneuropathy Masquerading As Diabetic Polyneuropathy, David Parkes, Russell Mordecai

Rowan-Virtua Research Day

New onset gait dysfunction often prompts admission to the hospital for further evaluation. The typical patient is an elderly person who normally is self-sufficient but had recently experienced a decline in their ability to care for themselves. Sometimes, however, those who present with gait dysfunction do not fit the expected demographic. These individuals raise concern for less common “zebra” presentations of neurological dysfunction. We describe one such rare case of a 39-year-old female with a new onset of type 2 diabetes mellitus and recent COVID-19 infection that presented to the emergency department with a sensation of bilateral lower extremity burning …

Spontaneous coronary artery dissection (SCAD) is a rare cause of acute coronary syndrome or sudden death. SCAD has a high incidence in a younger, female population with an association with peripartum or postpartum status. Connective tissue disorders and vasculitides are also associated with SCAD. The purpose of this poster will be to examine the presentation and risk factors associated with SCAD and to discuss optimal treatment strategies.

Case Report: Thyrotoxic Hypokalemic Periodic Paralysis, Kelly Schuitema, Wayne Tamaska, Robin Lahr

Rowan-Virtua Research Day

Thyrotoxic crisis, or thyroid storm, is an acute, life threatening event caused by hyperthyroidism with mortality up to 8-25% that can present with multi-system organ involvement. It is a rare, but well studied complication in the emergency department but can lead to further, less common complications. In this study we will discuss a case of thyrotoxic hypokalemic periodic paralysis. Thyrotoxic hypokalemic periodic paralysis (TPP) most commonly affects Asian men. The key features of the syndrome include acute onset of hypokalemia and paralysis. The hypokalemic aspect of the disorder is secondary to the shift intracellularly by thyroid hormones’ sensitization of Na+/K+-ATPase …

Case Report: Epigastric Abdominal Pain From Beverage Ingestion Of Freshly Squeezed Juice Of The Hardy Orange Flying Dragon Plant (Poncirus Trifoliata), James Espinosa, Alan Lucerna, David Ho

Rowan-Virtua Research Day

We report the case of a 25 year old male who presented to the ED with epigastric abdominal pain after ingesting a freshly squeezed beverage form of Flying Dragon Hardy Orange plant (Poncirus trifoliata). Poison control was contacted and recommended symptomatic treatment only. The patient’s pain resolved while in the emergency department. Seed and rind preparations have been used as an herbal remedy in East Asia. Freshly squeezed Poncirus trifoliata can cause significant abdominal pain.

Diaphragmatic Adjacencies: Pulmonary Embolism Presenting As Abdominal Pain, Joseph Piraneo, Christopher Schwartz, Russell Mordecai

Rowan-Virtua Research Day

Pulmonary embolism is a common yet potentially life-threatening diagnosis that should not be missed in the Emergency Department. Common presenting symptoms include dyspnea, pleuritic chest pain, cough, hemoptysis, syncope or pre-syncope. Less often, however, presenting symptoms can include abdominal pain. A clinician should recognize that pain adjacent to the diaphragm (including the lower chest and upper abdomen), can be secondary to underlying pathology either above or below the diaphragm. Here we describe an unusual case of pleuritic, post-prandial, right upper quadrant abdominal pain that was a result of pulmonary embolism.

Case Report: The Heart Breaking Tale Of Takotsubo In The Ed, Richard Baluyot, James Espinosa, Alan Lucerna, Sergey Medlenov, Joseph Pagano, Bhumi Shah

Rowan-Virtua Research Day

Chest pain is one of the most common chief complaints that emergency room physicians deal with on a daily basis. Here we present a rare cause of chest pain on a patient diagnosed with takotsubo cardiomyopathy. This is a condition that has been on the rise since its initial discovery and therefore clinicians should consider this on their differential when assessing patients with chest pain, especially postmenopausal women.
