The Medicine Forum

CASE PRESENTATION

A 72-year-old man with a past medical history of pancreatic adenocarcinoma status post biliary and duodenal stent placement presented to the emergency department for one week of cramping abdominal pain in the setting of a surveillance abdominal/pelvis computed tomography (CT) scan done two days prior to admission that showed massive pneumoperitoneum (Figure 1). The patient felt bloated but otherwise had no complaints on presentation. His physical exam was significant for marked abdominal distension with mild diffuse tenderness on palpation, normal bowel sounds, and no peritoneal findings of guarding or rebound. Given concern for perforated viscus causing pneumoperitoneum, he …

Results From A 78-Week, Single-Arm, Open-Label Phase 2 Study To Evaluate Ux007 In Pediatric And Adult Patients With Severe Long-Chain Fatty Acid Oxidation Disorders (Lc-Faod)., Jerry Vockley, Barbara Burton, Gerard T Berry, Nicola Longo, John Phillips, Pranoot Tanpaiboon, +Several Additional Authors

Pediatrics Faculty Publications

Long-chain fatty acid oxidation disorders (LC-FAOD) are rare disorders characterized by acute crises of energy metabolism and severe energy deficiency that may present with cardiomyopathy, hypoglycemia, and/or rhabdomyolysis, which can lead to frequent hospitalizations and early death. An open-label Phase 2 study evaluated the efficacy of UX007, an investigational odd-carbon medium-chain triglyceride, in 29 subjects with severe LC-FAOD. UX007 was administered over 78 weeks at a target dose of 25-35% total daily caloric intake (mean 27.5%). The frequency and duration of major clinical events (hospitalizations, emergency room visits, and emergency home interventions due to rhabdomyolysis, hypoglycemia, and cardiomyopathy) occurring during …

Ca2+, Astrocyte Activation And Calcineurin/Nfat Signaling In Age-Related Neurodegenerative Diseases, Pradoldej Sompol, Christopher M. Norris

Sanders-Brown Center on Aging Faculty Publications

Mounting evidence supports a fundamental role for Ca²⁺ dysregulation in astrocyte activation. Though the activated astrocyte phenotype is complex, cell-type targeting approaches have revealed a number of detrimental roles of activated astrocytes involving neuroinflammation, release of synaptotoxic factors and loss of glutamate regulation. Work from our lab and others has suggested that the Ca²⁺/calmodulin dependent protein phosphatase, calcineurin (CN), provides a critical link between Ca²⁺ dysregulation and the activated astrocyte phenotype. A proteolyzed, hyperactivated form of CN appears at high levels in activated astrocytes in both human tissue and rodent tissue around regions of amyloid and …

Enzyme Replacement Therapies: What Is The Best Option?, Azam Safary, Mostafa Akbarzadeh Khiavi, Rahimeh Mousavi, Jaleh Barar, Mohammad Rafi

Department of Neurology Faculty Papers

Despite many beneficial outcomes of the conventional enzyme replacement therapy (ERT), several limitations such as the high-cost of the treatment and various inadvertent side effects including the occurrence of an immunological response against the infused enzyme and development of resistance to enzymes persist. These issues may limit the desired therapeutic outcomes of a majority of the lysosomal storage diseases (LSDs). Furthermore, the biodistribution of the recombinant enzymes into the target cells within the central nervous system (CNS), bone, cartilage, cornea, and heart still remain unresolved. All these shortcomings necessitate the development of more effective diagnosis and treatment modalities against LSDs. …

A Case Report Of An Enlarged Suboccipital Nerve With Cutaneous Branch., Sasha Lake, Joe Iwanaga, Rod J Oskouian, Marios Loukas, R Shane Tubbs

Articles, Abstracts, and Reports

Variations of the suboccipital nerve are infrequently reported. This nerve derived from the C1 spinal nerve is usually a small branch that primarily innervates the short suboccipital muscles. During the routine dissection of the occipital region in an adult cadaver, a vastly enlarged left-sided suboccipital nerve was identified. The nerve innervated the short suboccipital muscles and overlying semispinalis capitis in normal fashion. However, it continued cranially to end in the overlying skin of the occiput. Although not normally thought to have a cutaneous branch, recalcitrant occipital neuralgia might be due to such a variant branch. Future studies are necessary to …

Mooney Face Stimuli For Visual Perception Research, Caspar M. Schwiedrzik, Lucia Melloni, Aaron Schurger

Psychology Faculty Articles and Research

In 1957, Craig Mooney published a set of human face stimuli to study perceptual closure: the formation of a coherent percept on the basis of minimal visual information. Images of this type, now known as "Mooney faces", are widely used in cognitive psychology and neuroscience because they offer a means of inducing variable perception with constant visuospatial characteristics (they are often not perceived as faces if viewed upside down). Mooney's original set of 40 stimuli has been employed in several studies. However, it is often necessary to use a much larger stimulus set. We created a new set of over …

Background: Health care and public health professionals rely on accurate, real-time monitoring of infectious diseases for outbreak preparedness and response. Early detection of outbreaks is improved by systems that are comprehensive and specific with respect to the pathogen but are rapid in reporting the data. It has proven difficult to implement these requirements on a large scale while maintaining patient privacy.

Objective: The aim of this study was to demonstrate the automated export, aggregation, and analysis of infectious disease diagnostic test …

Superior Cerebellar Arteries Originating From The Posterior Cerebral Arteries But Normal Course Of The Oculomotor Nerves., Dominic Dalip, Joe Iwanaga, Marios Loukas, Rod J Oskouian, R Shane Tubbs

Articles, Abstracts, and Reports

The posterior cerebral artery (PCA) is a branch of the terminal part of the basilar artery and perfuses the temporal lobes, midbrain, thalamus, and the posterior inferior portion of the parietal lobes. It is divided into P1-P4 segments. Variations in the P1 segment of the PCA are important to neurosurgeons when performing surgery, for example, on basilar tip aneurysms. We report bilateral superior cerebellar artery (SCA) arising from the P1 segment of the PCA. Such a configuration appears to be uncommon but should be kept in mind by neurosurgeons, neurointerventionalists, and neuroradiologists.

The Effect Of Abnormal Vitamin D Levels In Athletes., Jakub Sikora-Klak, Steven J Narvy, Justin Yang, Eric Makhni, F Daniel Kharrazi, Nima Mehran

Articles, Abstracts, and Reports

Vitamin D is a lipophilic prohormone integral to musculoskeletal, autoimmune, oncologic, cardiovascular, and mental health. Of particular importance to the orthopedic surgeon is the role of vitamin D in the regulation of bone mass, muscle strength, and physical performance. Although vitamin D-related skeletal pathologies are rare in industrialized nations, emerging research in the field has shown that most American adults have inadequate levels of vitamin D. Even among athletes, there is a high prevalence of vitamin D deficiency, which may place competitors at risk of stress fractures, illness, and delayed muscle recovery. Adequately identifying vitamin D-deficient individuals in need of …

Cancer Prevalence In Pakistan: Meta-Analysis Of Various Published Studies To Determine Variation In Cancer Figures Resulting From Marked Population Heterogeneity In Different Parts Of The Country, Romana Idress, Saira Fatima, Jamshid Abdul Ghafar, Ahmed Raheem, Zubair Ahmad

Department of Pathology and Laboratory Medicine

Background: Pakistan’s population is ethnically diverse with distinct ethnic groups inhabiting various parts of the country. Cancer statistics obtained from specific regions populated by distinct ethnic groups may vary considerably. There is no national cancer registry. To determine whether there are indeed significant statistical differences in cancer incidence and prevalence, data was recorded from different parts of Pakistan based on the ethnic composition of the population in those parts.
Methods: Ten papers (original articles) on cancer incidence and prevalence in Pakistan published in the last two decades were selected from PubMed and Google Scholar. Meta-analysis of findings of these studies …

Frequency Of Cd19, Qianzi Zhao, Lawrence K Jung

Medicine Faculty Publications

BACKGROUND: To understand the relationship between regulatory B cells (Bregs) and juvenile idiopathic arthritis (JIA), we analyzed the percentages of Bregs and their function in peripheral blood (PB) and synovial fluid (SF) of JIA patients.

METHODS: Twenty-one JIA patients and 11 children with growing pain but without known rheumatic diseases as controls were included. The B cell phenotype and intracellular production of IL-10 of Bregs were assessed by flow cytometry. Mononuclear cells from PB and SF were stimulated to produce IL-10 in vitro for the identification of IL-10- producing regulatory B cells.

RESULTS: The percentage of CD24

CONCLUSIONS: The inability …

Psoriasiform Sarcoidosis Presenting In Pregnancy And Treatment Considerations, Christian A. Albornoz, Jordan Wang, Matthew Keller

Department of Dermatology and Cutaneous Biology Faculty Papers

Cutaneous sarcoidosis is a common presentation for patients with sarcoidosis. Rarely, patients can present with psoriasiform lesions mimicking chronic plaque psoriasis. Here, we present a case of psoriasiform sarcoidosis in a pregnant patient. Pregnancy represents a unique challenge to systemic treatments if topical management fails. Tumor necrosis factor alpha inhibitors warrant special consideration during pregnancy.

Discriminating Radiation Injury From Recurrent Tumor With [18f]Parpi And Amino Acid Pet In Mouse Models, Patrick L. Donabedian, Susanne Kossatz, John A. Engelbach, Stephen A. Jannetti, Brandon Carney, Robert J. Young, Wolfgang A. Weber, Joel R. Garbow, Thomas Reiner

Publications and Research

Background

Radiation injury can be indistinguishable from recurrent tumor on standard imaging. Current protocols for this differential diagnosis require one or more follow-up imaging studies, long dynamic acquisitions, or complex image post-processing; despite much research, the inability to confidently distinguish between these two entities continues to pose a significant dilemma for the treating clinician. Using mouse models of both glioblastoma and radiation necrosis, we tested the potential of poly(ADP-ribose) polymerase (PARP)-targeted PET imaging with [¹⁸F]PARPi to better discriminate radiation injury from tumor.

Results

In mice with experimental radiation necrosis, lesion uptake on [¹⁸F]PARPi-PET was similar to …

Consensus On Molecular Subtypes Of High-Grade Serous Ovarian Carcinoma, Gregory M. Chen, Lavanya Kannan, Ludwig Geistlinger, Victor Kofia, Zhaleh Safikhani, Deena Ma Gendoo, Giovanni Parmigiani, Michael Birrar, Benjamin Haibe-Kains, Levi Waldron

Publications and Research

Purpose: The majority of ovarian carcinomas are of high-grade serous histology, which is associated with poor prognosis. Surgery and chemotherapy are the mainstay of treatment, and molecular characterization is necessary to lead the way to targeted therapeutic options. To this end, various computational methods for gene expression-based subtyping of high-grade serous ovarian carcinoma (HGSOC) have been proposed, but their overlap and robustness remain unknown.

Experimental Design: We assess three major subtype classifiers by meta-analysis of publicly available expression data, and assess statistical criteria of subtype robustness and classifier concordance. We develop a consensus classifier that represents the subtype classifications of …

The VAD Journal

Many studies have described differences in in-hospital outcomes and length of stay between patients treated for major cardiac conditions on weekdays versus weekends.¹ Our study aimed to explore the “weekend effect” on in-hospital care among patients with left ventricular assist devices.

Using data from the National Inpatient Sample (NIS) database, with a weighted estimate of more than 35 million admissions per year.² We identified patients 18 years or older with an ICD code signifying presence of a LVAD. Characteristics, comorbidities and clinical outcomes were compared between patients admitted on a weekend versus patients admitted on a weekday. The …

Reversible Manifestations Of Extraparenchymal Neurocysticercosis, Edison M. Campos, Flavius D. Raslau, Robert Salinas, Daniela Di Capua, John T. Slevin, Mauricio F. Villamar

Neurology Faculty Publications

Movement disorders are uncommon manifestations of neurocysticercosis. When present, most are secondary to parenchymal lesions in the basal ganglia. Rarely, movement disorders can occur in racemose/extraparenchymal neurocysticercosis, an aggressive variant frequently associated with cerebrospinal fluid outflow obstruction and hydrocephalus. Appropriate treatment can reverse neurological manifestations.

Journey Interrupted: A Phenomenological Exploration Of Miscarriage, Marit A. Watson, Vanessa D. Jewell, Sarah L. Smith

The Open Journal of Occupational Therapy

Background: Miscarriage is a significant life event that impacts occupational performance, identity, and competence and that influences perceptions of motherhood. Because of the lack of social rituals often attributed to the death of a loved one, miscarriages may result in disenfranchised grief, which impedes coping.

Methods: This phenomenological study explored the impact of miscarriage on relationships, perceptions of motherhood, and the meaning of occupation in the context of grief. Data was collected through semi-structured interviews (N = 4) and completion of a brief demographic questionnaire. The interviews were digitally recorded, transcribed verbatim, and reviewed to ensure accuracy. Using inductive thematic …

Noninvasive Hemodynamic Monitoring In Emergency Trauma Patients, Ryan Boyd

Nurse Anesthesia Student Capstones

Noninvasive hemodynamic monitoring has evolved steadily over the past few decades in response to healthcare providers' preference for less invasive monitoring methods for their patients. Invasive monitoring has its place in the critically ill patient population as witnessed in intensive care units throughout the country. Even in this environment, providers are opting less for the pulmonary artery catheter which has been the gold standard for invasive cardiac output monitoring in the past. Providers are now utilizing less invasive monitoring techniques which offer fewer potential complications to the patient while providing rapid access to critically important hemodynamic data. Examination of different …

The Utilization Of Laryngeal Mask Airways Vs. Endotracheal Tubes In Pediatrics With Upper Respiratory Tract Infection In Reducing Airway Complications, Ruby Foster

Nurse Anesthesia Student Capstones

According to Tait & Malviya, (2005) children typically experience six to eight upper respiratory infections (URIs) per year with ninety-five percent being viral in etiology (Tait & Malvia, 2005). URIs commonly occur in the pediatric population (Bernando-Ocampo, 2012). An issue surrounding the debate on whether a child with upper respiratory infection (URI) should proceed with surgery or cancel surgery is a debate that has been ongoing for several years (Tait el al. 2005). This review examines whether children who have an URI scheduled for surgery are at an increased risk for adverse respiratory complications when the laryngeal mask airway (LMA) …

Opioid Administration And Prescribing In Older Adults In U.S. Emergency Departments (2005-2015)., Erin M Marra, Maryann Mazer-Amirshahi, Peter Mullins, Jesse M Pines

Emergency Medicine Faculty Publications

Introduction: We assess trends in opioid administration and prescribing from 2005-2015 in older adults in United States (U.S.) emergency departments (ED).

Methods: We analyzed data from the National Hospital Ambulatory Medical Care Survey (NHAMCS) survey from 2005 to 2015. ED visits for painful conditions were selected and stratified by age (18-64, 65-74, 75-84, ≥ 85 years). We analyzed trends in opioid administration in the ED and prescribing at discharge to encounters ≥ 65 and assessed predictors of use using survey-weighted chi-square tests and logistic regression. Trends in the use of five commonly prescribed opioids were also explored.

Results: Opioid administration …
