A Clinical Assessment: Counseling Families On Timing Of Colorectal Cancer Screening, Bertilia Tavarez, Md, Hamzah Shariff, Md, Breanne Mcdermott, Bs, Sanjna Shelukar, Md, Limi Jamma, Md, Sonali Shah, Md, Akash Patel, Do, Christopher Henry, Md, Aaron Martin, Md

The Medicine Forum

Colorectal cancer (CRC) remains the second most common cause of cancer mortality in the United States. Current recommendations advise initiating colonoscopy at age 40, or 10 years earlier than the youngest affected first-degree relative (FDR), in individuals with a family history of CRC or advanced polyps (AP). Despite these guidelines, their translation into routine clinical counseling is not well defined. This study examines how often patients with CRC or AP receive guidance about early screening for FDRs.

A retrospective review was performed using electronic health records from an urban academic center. Patients diagnosed with CRC or AP between January 2019 …

Commentary On The Withdrawal-Af Trial And Its Applicability In Select Patient Populations, David Zhang, Md

The Medicine Forum

Segan et al. report that 90% of patients with atrial fibrillation- mediated cardiomyopathy (AFCM) maintained left ventricular ejection fraction (LVEF) ≥50% af ter withdrawing heart failure therapy following successful rhythm control.¹ While these results challenge the current practice of indefinite guideline-directed medical therapy (GDMT) in patients with improved ejection fraction, two important questions remain before these findings can be applied more broadly: which patients are appropriate candidates for withdrawal, and how should they be monitored?

The trial excluded patients with coronary disease, structural heart disease, and AF duration exceeding one year. This approach reveals a fundamental challenge, distinguishing pure …

Sudden Syncope Due To Intra Hisian Block With Severely Prolonged His–Ventricular Interval Diagnosed On Electrophysiology Study, Sheraz Qamar, Md, Meiqi Luo, Md

The Medicine Forum

Syncope is a common cause of emergency department evaluation in older adults, when sudden loss of consciousness without prodromal symptoms raises concern for cardiac etiology. We present this case of an 80 year old woman with a prior history of vasovagal syncope who presented after a collapse. Initial evaluation, including electrocardiogram, telemetry, echocardiogram, and ambulatory monitoring, was unrevealing. Given the high risk clinical features such as lack of prodromal symptoms and sudden collapse, an inpatient electrophysiology (EP) study was pursued and demonstrated severe intra Hisian conduction disease with split His bundle electrograms and a markedly prolonged His–ventricular interval. A permanent …

A Strain On The Heart: The Hidden Threat Of Ventricular Tachycardia, Sheraz Qamar, Md, Meiqi Luo, Md, Naila Ijaz, Md, Behzad Pavri, Md, Facc, Praveen Mehrotra, Md, Facc

The Medicine Forum

Mitral valve prolapse (MVP) is increasingly recognized to have an arrhythmic phenotype associated with ventricular arrhythmias and sudden cardiac death independent of mitral regurgitation severity. Mitral annular disjunction (MAD) is a key structural abnormality implicated in abnormal myocardial mechanics and myocardial fibrosis. We describe a patient with MVP and MAD who developed recurrent non-sustained ventricular tachycardia in association with markedly abnormal basal lateral wall longitudinal strain and progressive myocardial fibrosis on cardiac magnetic resonance imaging. Surgical mitral valve repair performed for MAD resulted in resolution of annular disjunction, improvement in regional myocardial strain, and elimination of ventricular arrhythmias. This case …

Lvad Patient With Delayed Family Involvement Due To Incarceration, J. Marco Cipriaso, Md, Kathleen Mechler, Md

The Medicine Forum

Left ventricular assist device (LVAD) placement requires an extensive support system for success. Patients who are incarcerated face unique challenges in achieving this due to prison rules. We describe a case in which an LVAD patient suffered a massive intracranial hemorrhage, leaving him unable to make his own decisions. Medical teams did not involve his family in admissions for his slow chronic decline, but family were asked to make decisions for him at this acute change causing them significant distress. We advocate that families of incarcerated patients be more routinely involved in provider communications and education related to their chronic …

Isolated Left Ventricle Apical Non-Compaction- A Diagnostic Conundrum, Trisha Sindhu, Md, Ranjita Sengupta, Md

The Medicine Forum

Left ventricular non-compaction (LVNC) cardiomyopathy is a rare myocardial disorder characterized by abnormal morphogenesis of the left ventricle (LV). It is typically associated with additional cardiac abnormalities and is most often diagnosed in childhood.¹ We present a unique case of isolated LVNC in a 42-year-old, physically active African American police officer. This case highlights an uncommon presentation of LVNC and underscores the variable specificity of current diagnostic criteria across diverse patient populations.³

A Dose Of Trouble: A Case Of Furosemide Exacerbating Amiodarone-Induced Hypothyroidism, Muneeba Ali, Md, Enad Haddad, Md, Warda Naqvi, Md, Ayesha Afzal, Md, Eddy Mizrahi, Md

The Medicine Forum

Heart failure with reduced ejection fraction is a clinical condition that often requires the concurrent use of multiple medications. Unfortunately, cross reactivity between multiple drugs occurs frequently. Today, we present the case of a 79-year-old male with heart failure and atrial fibrillation on long term amiodarone therapy. His furosemide dose was increased from 40 milligrams (mg) to 80 mg after he developed bilateral lower extremity swelling. The patient eventually developed generalized joint pains, weakness, difficulty maintaining balance, and frequent falls. He reported to the Emergency Department (ED), where he was noted to be suffering from severe acute kidney injury (AKI), …

Ascending Aortic Thrombus With Systemic Embolization: Implications For Risk Stratification And Management, Warda Naqvi, Md, Moses Morgan, Md, Muneeba Ali, Md, Enad Haddad, Md, Zaineb Alhassani, Md

The Medicine Forum

Ascending aortic thrombus is an uncommon clinical finding, particularly in the absence of significant underlying aortic disease, yet it poses a substantial risk for systemic embolization. We describe a 53-year-old woman with a history of cocaine use who presented with acute neurologic deficits and was found to have a left middle cerebral artery occlusion requiring mechanical thrombectomy. Cross-sectional imaging incidentally identified a 1.8 cm thrombus within the ascending aorta. Anticoagulation with intravenous heparin was initiated, however, her clinical course was complicated by recurrent embolic phenomena, including renal infarction and bowel perforation consistent with mesenteric ischemia. Ongoing deterioration with multiorgan failure …

Approximately 1.3 billion adults worldwide have hypertension.¹ Between 2006 and 2013, there was a two-fold increase in Emergency Department visits for hypertensive emergency.² The prevalence of hypertensive emergency ranges from 0.08% to 0.76% in patients presenting to the Emergency Department.^1,3-6 The estimated incidence of hospitalization with a hypertensive emergency is 111 per 100,000 patients.^1,7 Hypertensive emergency is also associated with significant morbidity and mortality, often leading to ischemic stroke, pulmonary edema, acute heart failure.^3-6 In-hospital mortality among patients with hypertensive emergency varies between 0.48% and 12.5%.^5,7 This retrospective cohort study aims to further clarify …

Using United States Medicare Program Claims To Identify Reliable Measures Of Low Value Services Influenced By Primary Care Physician Decisions, Chris Fleming, Dmitriy Poznyak, Rhea E. Powell, Claire Erba, Eunhae Shin, Rui Wang, Claire Burkhart, Arkadipta Ghosh, Eugene C. Rich

Division of Internal Medicine Faculty Papers & Presentations

BACKGROUND: Low-value services (LVS) are those that “… provide little to no benefit to patients….”¹ Among an existing set of 31 LVS are invasive procedures not typically performed by primary care physicians (PCPs), and other LVS that may be commonly provided by specialists. To facilitate research on the role of primary care physicians in low-value care, we sought to identify the reliability of two subsets of LVS measures that are more directly subject to PCPs’ decisions. We refer to these as primary care adjacent (“PCA”) LVS measures.

METHODS: Retrospective observational cohort study to identify which of a 31-item LVS …

Targeting Inequities: Addressing Lung Cancer Care Challenges In Africa Through Drug Access, Radiotherapy, And Surgical Innovations, Elvis Obomanu, Chidiebube Ugwu, Muluken Megiso, Tarfa Verinumbe, Colton Jones, Verna Vanderpuye, Nazik Hammad

Division of Internal Medicine Faculty Papers & Presentations

Lung cancer remains one of the leading causes of cancer-related mortality in Africa, with survival rates starkly lagging behind global benchmarks because of systemic inequities in prevention, diagnosis, and treatment access. Despite representing only 6% of global smokers, the continent faces a disproportionate burden driven by environmental and occupational carcinogens, aggressive tobacco marketing, and fragmented health care infrastructure. Key challenges include prohibitive delays in accessing targeted therapies like epidermal growth factor receptor inhibitors and immunotherapies, a dire shortage of radiotherapy infrastructure-0.12 megavoltage units per million people versus the International Atomic Energy Agency's recommended five megavoltage units per million, and a …

Polymorphic Ventricular Tachycardia, Sarcoidosis, And The Ultimate Unmasking Of A Pheochromocytoma, Anusha U. Saga, Elizabeth Clark, Isaac R. Whitman

Department of Medicine Faculty Papers

The pitfall of anchoring bias may contribute to diagnostic conundra. In this case, a patient with a history of systemic sarcoidosis presented to the electrophysiology clinic with palpitations. Rhythm monitoring revealed polymorphic ventricular tachycardia (PMVT). A diagnosis of cardiac sarcoidosis was presumed and pursued even though repeat cardiac imaging was negative. In the interim, the patient developed new hypertension, and the patient’s primary care provider screened the patient for pheochromocytoma. Despite the initial pursuit of a misdiagnosis in a patient with a high pretest probability for the wrong diagnosis, the pheochromocytoma was resected and the PMVT and hypertension was cured.

Abington Jefferson Health Papers

Introduction: Community-acquired pneumonia (CAP) is one of the leading causes of death globally. Changing antibiotic resistance profiles, paucity of reliable CAP mortality prediction models, and ageing populations will increase its burden. This study aims to evaluate adherence to CAP management guidelines as well as develop an ML-based mortality prediction model.

Methods: This retrospective, chart review included all CAP cases between 2016 and 2021. Variables collected included patients' demographics, comorbidities, vitals, laboratory, imaging, and culture findings, as well as initial and targeted antibiotic regimens. Data was pre-processed and analysed in python-3. Adherence to the American thoracic society/infectious diseases society of America …

Atrial Fibrillation In Athletes: Mechanisms, Management, And Future Directions, Ibrahim Alameh, Ghina Al Fout, Michael D. Ezekowitz, Mohammed Kamareddine

Department of Medicine Faculty Papers

BACKGROUND: High-volume endurance training may shift exercise from cardioprotective to arrhythmogenic, increasing the risk of atrial fibrillation (AF) in healthy athletes.

CASE SUMMARY: A 38-year-old marathon runner with a 15-year history of high-intensity endurance training presented with episodic palpitations and reduced athletic performance. Electrocardiogram showed paroxysmal AF; echocardiography revealed mild left atrial enlargement without structural heart disease. Symptoms worsened during the recovery phase after runs, suggesting vagally mediated AF. After unsuccessful flecainide therapy, he underwent pulmonary vein isolation. Twelve months later, he remained free of recurrent AF on Holter monitoring and successfully resumed endurance training following an 8-week recovery period. …

Infectious Aortitis Secondary To Gastrointestinal Pathogens: A Case Series And Syndromic Review, Natasa Kostic, Ilana Goldberg, Devin Weber

Division of Internal Medicine Faculty Papers & Presentations

Aortitis is a rare but serious complication of infection that results in high morbidity and mortality. The most common location is in preexisting aneurysmal disease in a patient with multiple chronic comorbidities. The pathogens often reflect gastrointestinal bacteria, the classic example being Salmonella spp., but also include other enteric flora, Staphylococcus aureus, Streptococcus spp., and more. Herein, we describe 2 cases of aortitis caused by gastrointestinal bacteria and review management of this complex syndrome.

Defining A Multi-Omic, Ai-Enabled Stool Screening Paradigm For Colorectal Cancer: A Consensus Framework For Clinical Translation, Arturo Loaiza-Bonilla, Yan Leyfman, Viviana Cortiana, Rhys Crawford, Shivani Modi

Einstein Health Papers

Colorectal cancer (CRC) develops through both conventional adenoma-carcinoma and serrated neoplasia pathways, yet noninvasive screening still under-detects the advanced precursor lesions that enable true cancer prevention. Stool-based screening reduces CRC mortality, but its preventive impact remains constrained by limited detection of advanced precancerous lesions (APLs), including advanced adenomas and sessile serrated lesions. Next-generation multitarget stool DNA assays (mt-sDNA; e.g., Cologuard Plus) have established high sensitivity for CRC and specificity approaching 94%, leaving improved APL detection as the principal opportunity for innovation. This review presents a consensus framework for a multi-omic stool screening paradigm that integrates host epigenetic markers (DNA methylation) …

A Novel Laparoscopic Renal Denervation System In A Preclinical Swine Model, Linwei Zhao, Wei Yang, Binbin Zhu, Yahui Liu, Peng Tian, Xinyu Guo, Yang Dong, Zhiqiang Fan, Huiping Li, Yu Feng, Lijie Zhu, Minfu Bai, Qiuping Zhao, Xingkun Zhang, Chenchen Si, Qianqian Cheng, Gan-Xin Yan, Chuanyu Gao

Department of Medicine Faculty Papers

Laparoscopic renal denervation (RDN) represents a specialized approach for hypertension, particularly when conventional methods face limitations. While catheter-based RDN has demonstrated significant efficacy in recent large-scale clinical trials and has been integrated into international guidelines, its effectiveness can be constrained by complex renal anatomy or incomplete ablation. We developed a novel laparoscopic RDN system, comprising an integrated radiofrequency (RF) clamp, RF generator, and cooling pump, to achieve more controlled adventitial ablation. This study aims to evaluate the safety, feasibility, and optimal parameters of this new system in a preclinical swine model. Sixteen pigs were divided into an immediate group ( …

From Stemi To Saddle Pulmonary Embolism: Management Challenges And The Role Of Va-Ecmo, Enad Haddad, Irfan Ahsan, Sudeep Nugooru, Gregary D. Marhefka

Division of Internal Medicine Faculty Papers & Presentations

Acute pulmonary embolism and acute myocardial infarction are critical conditions with overlapping presentations, and their coexistence can be catastrophic. We report a 45-year-old man with prior mid LAD stent who presented with chest pain and ventricular fibrillation arrest, diagnosed with inferior/posterior STEMI. Emergent PCI to the mid RCA restored stability. The patient developed persistent hypoxia over the next two days requiring intubation and mechanical ventilation. Worsening hypoxia and shock prompted urgent transesophageal echocardiography to evaluate for mechanical complications, instead revealing a mobile echo density spanning the right and left main pulmonary arteries, consistent with acute saddle pulmonary embolism, and right …

Rapid Inpatient Methadone Induction In The Fentanyl Era: A Systematic Review Of Safety, Efficacy, And Protocols For Hospitalized Patients With Opioid Use Disorder, Lorik Berisha, Sapan Patel, Charlotte Pirquet, Navina Magesh Kumar, Yousef Soliman, Ahsan Ullah, Daniel M. Matassa

Division of Internal Medicine Faculty Papers & Presentations

Purpose of Review: The potency of illicit fentanyl has rendered standard methadone inductions inadequate for many hospitalized adults with opioid use disorder. Standard protocols often fail to achieve therapeutic doses quickly enough to manage withdrawal and cravings in fentanyl-tolerant individuals, contributing to poor retention and higher self-discharge rates. This review examines emerging evidence on dosing strategies, outcomes, and safety of rapid methadone inductions in acute-care hospitals. Recent Findings: Nine studies (five retrospective cohorts, four case series/reports) encompassing 380 patients met inclusion criteria. Median starting doses were 30–40 mg (range 20–90 mg), with daily or symptom-triggered increases achieving 60–100 mg within …

New Therapies, New Challenges: Cystic Lung Disease After Cancer Immunotherapy, Ananya Venkatesh, David Camacho, Ross Summer, Michael Dong

Division of Internal Medicine Faculty Papers & Presentations

Immunotherapies have reduced reliance on cytotoxic strategies with their associated high toxicity levels, revolutionizing cancer care. However, these targeted therapies have also increased prevalence of previously rare sequelae, impacting patients experiencing longer survival. We describe a case of endometrial adenocarcinoma with lung metastases, in which tumor resolution following immunotherapy created cystic airspaces, leading to a pneumothorax complication. A 49-year-old female with advanced stage endometrial adenocarcinoma and lung metastasis developed cystic lung lesions in areas of previous metastatic lesions after treatment with Pembrolizumab and Bevacizumab. She developed a pneumothorax secondary to the rupture of one of the large lung cysts, leading …

Cytomegalovirus As A Potential Trigger For Acute Coronary Syndrome: A Case Of Nstemi In A Previously Healthy Patient, Hussam Al Hennawi, Muhammad Sabri, David Teng, Maxwell Berman, Botros Shenoda

Abington Jefferson Health Papers

Cytomegalovirus (CMV) infection has been implicated in endothelial dysfunction and atherogenesis, yet its role as a potential trigger for acute coronary syndrome (ACS) remains underrecognized. We present a case of a 32-year-old male with no prior medical history who developed non-ST elevation myocardial infarction (NSTEMI) and was subsequently found to have active CMV infection. The patient had no known history cardiovascular disease, though subsequent testing did reveal additional underlying risk factors. This case highlights the need to consider infectious etiologies, including CMV, as contributors to ACS in young, otherwise apparently healthy individuals. Understanding the interplay between viral infections and atherosclerotic …

A Rare Case Of Chilaiditi Syndrome As A Driver Of Chronic Respiratory Failure, Paige C. Adams, Daniel Kramer

Division of Pulmonary, Allergy, and Critical Care Medicine Faculty Papers

Chilaiditi sign is a rare radiographic finding demonstrating interposition of the colon between the liver and the diaphragm; Chilaiditi syndrome is the manifestation of gastrointestinal or respiratory symptoms secondary to this finding. This syndrome rarely can be associated with acute and chronic respiratory failure. We report a case of a 66-year-old woman with chronic hypercapnic and hypoxemic respiratory failure due to severe restrictive pulmonary mechanics in the setting of Chilaiditi syndrome. Imaging showed an elevated right hemidiaphragm initially concerning for hemidiaphragm paralysis; however a fluoroscopic Sniff test suggested normal diaphragm function. Despite hospitalisation for aggressive bowel decompression combined with noninvasive …
