Pulmonary Alveolar Microlithiasis Diagnosed With Radiography, Ct, And Bone Scintigraphy, Emad Alkankan, Hasan Yamin, Hazim Bukamur, Fadi Alkhankan, Yousef Shweihat, Fuad Zeid

Internal Medicine

Pulmonary alveolar microlithiasis is rare disease characterized by accumulation of calcium phosphate microlithis in the alveoli. The pathogenesis relates to mutation in the gene SLC34A2 (solute carrier family 34 member 2) located on chromosome 4p15.2, which produces a defective sodium-phosphate cotransporter in alveolar epithelial type-2 cells, making these cells unable to clear phosphorus released during recycling of surfactant.

Pick’S Disease And Subdural Haematoma: A Diagnostic Red Herring, Philip Adebayo, Funmilola Taiwo, Fatma Bakshi, Sunham Nur

Internal Medicine, East Africa

Frontotemporal dementia (FTD), otherwise known as Pick’s disease, is a clinically heterogeneous group of sporadic and familial neurodegenerative diseases. These conditions are characterized by dementia, behavioural and language dysfunction and loss of executive skills resulting from the degeneration of the frontal and temporal lobes. Although reversible causes of dementia are always sought during the evaluation of patients with progressive cognitive decline, the occurrence of a reversible aetiology may distract from evaluating for neurodegenerative causes of dementia. This report is about a 66-year old man with features of FTD and superimposed chronic subdural haematoma.

Tumor Heterogeneity As A Predictor Of Response To Neoadjuvant Chemotherapy In Locally Advanced Rectal Cancer, Alissa Greenbaum, David R. Martin, Therese J. Bocklage, Ji-Hyun Lee, Scott A. Ness, Ashwani Rajput

Pathology and Laboratory Medicine Faculty Publications

BACKGROUND: Neoadjuvant chemoradiotherapy (nCRT) is the standard of care for locally advanced adenocarcinoma of the rectum, but it is currently unknown which patients have disease that will respond. This study tested the correlation between response to nCRT and intratumoral heterogeneity using next-generation sequencing assays.

PATIENTS AND METHODS: DNA was extracted from formalin-fixed, paraffin-embedded biopsy samples from a cohort of patients with locally advanced rectal adenocarcinoma (T3/4 or N1/2 disease) who received nCRT. High read-depth sequencing of > 400 cancer-relevant genes was performed. Tumor mutations and variant allele frequencies were used to calculate mutant-allele tumor heterogeneity (MATH) scores as measures of intratumoral …

Aminophylline Shortage And Current Recommendations For Reversal Of Vasodilator Stress: An Asnc Information Statement Endorsed By Scmr, Aiden Abidov, Vasken Dilsizian, Rami Doukky, W Lane Duvall, Christopher Dyke, Michael D Elliott, Fadi G Hage, Milena J Henzlova, Nils P Johnson, Ronald G Schwartz, Gregory S Thomas, Andrew J Einstein

Pharmacologic reversal of serious or intolerable side effects (SISEs) from vasodilator stress is an important safety and comfort measure for patients experiencing such effects. While typically performed using intravenous aminophylline, recurrent shortages of this agent have led to a greater need to limit its use and consider alternative agents. This information statement provides background and recommendations addressing indications for vasodilator reversal, timing of a reversal agent, incidence of observed SISE with vasodilator stress, clinical and logistical considerations for aminophylline-based reversal, and alternative non-aminophylline based reversal protocols.

Prevalence And Outcome Of Asymptomatic Cryptococcal Antigenemia In Art Naive And Art Experienced Hiv Patients In Dar Es Salaam, Tanzania, Charles Mandela Makakala

Master of Medicine in Internal Medicine

Introduction: Cryptococcal meningitis (CM) is a highly fatal disease and contributes to about 20% of all-cause mortality in HIV/AIDS. Sub-Saharan Africa is facing substantial challenges in the treatment of the disease; the focus has been shifted towards prevention of the condition in ART-naive patients with CD4 counts of less than 100 cells/μL. Most studies and interventions have been conducted on ART-naive HIV patients despite there being cases and deaths due to cryptococcal meningitis among ART-experienced patients. Recent studies have shown that although there is an increase in ART coverage among HIV patients, this has not affected the incidence of cryptococcal …

Faculty, Staff and Student Publications

The European Society of Gastrointestinal Endoscopy (ESGE) together with the United European Gastroenterology (UEG) recently developed a short list of performance measures for small-bowel endoscopy (i.e. small-bowel capsule endoscopy and device-assisted enteroscopy) with the final goal of providing endoscopy services across Europe with a tool for quality improvement. Six key performance measures both for small-bowel capsule endoscopy and for device-assisted enteroscopy were selected for inclusion, with the intention being that practice at both a service and endoscopist level should be evaluated against them. Other performance measures were considered to be less relevant, based on an assessment of their overall importance, …

T cells in chronic viral infections are featured by premature aging with accelerated telomere erosion, but the mechanisms underlying telomere attrition remain unclear. Here, we employed human CD4 T cells treated with KML001 (a telomere-targeting drug) as a model to investigate the role of telomere integrity in remodeling T cell senescence. We demonstrated that KML001 could inhibit cell proliferation, cytokine production, and promote apoptosis via disrupting telomere integrity and DNA repair machineries. Specifically, KML001-treated T cells increased dysfunctional telomere-induced foci (TIF), DNA damage marker γH2AX, and topoisomerase cleavage complex (TOPcc) accumulation, leading to telomere attrition. Mechanistically, KML001 compromised telomere integrity …

Aortic Valve Calcium Score Indexed To Transaortic Valve Gradient: A Novel Hemodynamic And Anatomic Index For Patients With Low Gradient Aortic Stenosis., Ramy Mando, George S Hanzel, Francis Shannon, Ashish Chaddha, Craig Tucker, Michael Gallagher, Robert D Safian, Amr E Abbas

Conference Presentation Abstracts

Background Aortic valve calcium score (AVCS) is a marker for aortic stenosis (AS) severity. We sought to evaluate the effect of aortic valve (AV) variables of flow defined by stroke volume index (SVI), area (AVA), and gradient (MG) on AVCS and study the role of AVCS/MG ratio in patients with low gradient AS.

Methods We retrospectively studied patients undergoing transcatheter aortic valve replacement (TAVR) for severe AS (defined by Echo, Cath, and multimodality team consensus) at our institution from January 1, 2014 through September 1, 2018. AVCS was compared among patient groups defined by their MG (low < or high ≥40 mmHg), echocardiographic SVI (low < or normal ≥35 mL/m2), and AVA (< 0.8 or ≥0.8 cm2) using a three-way factorial ANOVA. The AVCS/MG ratio was developed and compared to AVCS and AVCS/cm2 (annular area) to identify severe AS in patients with low gradient. AVCS/MG was developed based on AVSC (AU) 2000 in males, and 1600 in females/ 40 mmHg (50 and 30, retrospectively)

Should A Fully Covered Self-Expandable Biliary Metal Stent Be Anchored With A Double-Pigtail Plastic Stent? A Retrospective Study, Saad Emhmed Ali, Wesam M. Frandah, Leon Su, Cory Fielding, Houssam Mardini

Internal Medicine

Background: The migration rate of fully covered self-expandable metal stents (FCSEMSs) has been reported to be between 14% to 37%. Anchoring of FCSEMSs using a double-pigtail plastic stent (DPS) may decrease migration. Aim: To compare stent migration rates between patients who received FCSEMS alone and those who received both an FCSEMS and anchoring DPS. Methods: We conducted a retrospective analysis of endoscopy reporting system and medical records of 1366 patients who underwent endoscopic retrograde cholangiopancreatography (ERCP) with FCSEMS placement at the University of Kentucky health care. Between July 2015 and April 2017, 203 patients with FCSEMS insertion for the treatment …

The Effect Of Home Blood Pressure Monitoring And Self-Titration On Achieving Blood Pressure Targets, Katina A. Varner

Evidence-Based Practice Project Reports

One-third of U.S. adults over the age of 20 are hypertensive, with an estimated cost of $47.5 billion in direct medical expenses and increased individual CVD risk (CDC, 2018). Routine office visits afford primary care providers a means of managing hypertension; however, time constraints limit the ability to accurately assess and track BP in most patients (Jung, 2015). The purpose of this project was to determine if implementation of HBPM and an algorithm for selftitration of antihypertensive medications increased the number of participants at guideline recommended BP goal over a 90-day period. The Health Promotion Model provided the theoretical framework …
