Journal of Community Hospital Internal Medicine Perspectives

Background: Extrapulmonary tuberculosis (EPTB) accounts for ~20% of Mycobacterium tuberculosis infections in Pakistan. Diagnostic delays are common and may worsen outcomes. We evaluated whether empiric treatment initiation improves outcomes among patients with EPTB at a large public hospital in Islamabad, Pakistan. Methods: Retrospective cohort of consecutive EPTB cases at Pakistan Institute of Medical Sciences (January–June 2016). Patients were categorized as clinically diagnosed (symptoms/radiology) or laboratory-supported (histology, microbiology, or biochemical tests). Standard Directly Observed Therapy Short-course (DOTS) based regimens were used. Outcomes were treatment success, failure, loss to follow-up, and mortality; groups were compared using chi-square testing. Results: Of 317 EPTB …

A Case Report Of Mesalazine-Induced Pulmonary Injury In A Patient With Ulcerative Colitis, Vasileios Paraschou, Vasileios Papavasileiou, Ilektra Voulgareli, Vasilios Tzilas

HCA Healthcare Journal of Medicine

Introduction

Mesalazine (5-aminosalicylic acid) is widely used as a first-line therapy for ulcerative colitis (UC) due to its efficacy and safety profile. Rarely, it can cause pulmonary toxicity with variable clinical and radiologic manifestations, making diagnosis challenging.

Case Presentation

We report the case of a 52-year-old woman with UC who developed persistent fever and progressive exertional dyspnea following escalation of mesalazine dosage. Imaging revealed diffuse bilateral ground-glass opacities, while infectious and UC-related pulmonary causes were excluded. Pulmonary function testing demonstrated restriction and markedly reduced diffusing capacity. Following mesalazine discontinuation and initiation of corticosteroid therapy, the patient experienced rapid symptomatic, functional, …

Beta2-Agonist And Anti-Inflammatory Combination Therapy For Asthma Rescue: A Paradigm Shift In Asthma Care, Neil Skolnik, Jessica Stieritz, Julie Akers, Timothy Hudd, Wendy L. Wright, Ileen Gilbert, Nazrin Yusufova, Bill Cook, Emily Robb, Henry Naddaf

Abington Jefferson Health Papers

The Global Initiative for Asthma (GINA) report and national and international guidelines have shifted away from short-acting beta2-agonist (SABA)-only bronchodilators as first-line asthma rescue therapy, recognizing that both bronchoconstriction and inflammation underlie the increase in symptoms preceding an exacerbation. Instead, the GINA Committee supports strategies to reduce inflammation, such as anti-inflammatory reliever (AIR) therapy (as-needed, low-dose inhaled corticosteroid [ICS]–formoterol or SABA–ICS for symptom relief) and single maintenance and reliever therapy (SMART) or maintenance and reliever therapy (MART; i.e., ICS–formoterol used as both maintenance and as-needed rescue therapy). This narrative review discusses the rationale behind the move toward AIR and SMART …

Lungs And Beyond: Seizures As Presenting Symptom In A Patient With Mycobacterium Chimaera Infection, Samar Mehyar, Tripti Adhikari, Shweta Kambali, Harneet K. Ghumman, Avneet K. Ghumman, Parul Sud, Mehrshad Fathian Sabet, Elizabeth Mikhail, Sohrab Singh

Journal of Community Hospital Internal Medicine Perspectives

Mycobacterium chimaera is a slow-growing, non-tuberculous mycobacterium (NTM) that belongs to the Mycobacterium avium complex (MAC). It first emerged as a pathogen after being associated with infections in patients who underwent cardiothoracic surgery when patients were getting exposed to heater cooler units, especially those requiring extracorporeal membrane oxygenation (ECMO) or prosthetic valve placement. We report an atypical presentation of M. chimaera infection in a patient with COPD, but no prior history of cardiac surgery or immunosuppression.

Quantifying Black Carbon Concentrations in Georgia and Analyzing Associated Public Health Risks

One of the most daunting challenges of the industrial world is air pollution. Within this broad spectrum, there is an inhalable particle group named PM2.5, which contains black carbon. Black carbon has evidence that supports the generation and worsening of adverse health impacts, which may include birth complications, cognitive deficits in children, pulmonary aggravation, asthma, cardiovascular issues, neurological degenerative patterns, and cancer risk. This is especially seen in vulnerable populations, like children, elderly, and those who already suffer from weakened health, many of which reside in the southern …

A Case Of Successful Survival In A High-Risk Elderly Patient With Copd After Endotracheal Intubation, Julia Cueto Oms-Ii

Rowan-Virtua Research Day

Exacerbations of chronic obstructive pulmonary disease (COPD) leading to acute respiratory failure (ARF) is one of the major causes of mortality worldwide, thus typically having poor outcomes. Risk factors such as the need for invasive mechanical ventilation (IMV), severity of disease, comorbidities, and increased age are predictors of increased mortality rates in COPD patients. Noninvasive ventilation (NIV), like bilevel positive airway pressure (BiPAP) or high flow nasal cannula (HFNC), is the initial standard of care for acute exacerbations of COPD. However, longer periods of NIV and failure of NIV therapy can lead to delayed endotracheal intubation and higher mortality rates. …

We evaluated the association between GLP-1 agonist use and fractures, osteoporosis, vitamin D deficiency, falls, hospitalizations, and mortality in OSA patients without baseline fractures, osteoporosis, vitamin D deficiency, or alcohol use disorder.

Methods: A retrospective cohort study was conducted using the TriNetX Global Collaborative Network. Adults (≥50 years) with OSA and BMI ≥18.5 kg/m² …

Case Report: Bilateral Pneumothorax Following T2–T5 Medial Branch Nerve Block, Jenna Rapone Md

Rowan-Virtua Research Day

Bilateral pneumothorax is an uncommon but clinically significant complication of thoracic spinal interventions. We report the case of a 20-year-old female with underlying scoliosis who developed acute pleuritic chest pain, dyspnea, and persistent cough immediately following bilateral T2–T5 medial branch nerve block injections performed in an outpatient pain management setting.  Thoracic medial branch blocks are generally considered low-risk procedures; however, the proximity of the pleura to posterior thoracic elements places patients at risk for iatrogenic pleural injury, particularly in individuals with altered spinal anatomy such as scoliosis. This case underscores the importance of maintaining a high index of suspicion for …

Case Report: Necrotizing Pneumonia, Veroneka Mikhail Md

Rowan-Virtua Research Day

Necrotizing pneumonia is an uncommon but severe complication of community-acquired pneumonia (CAP), characterized by progressive parenchymal liquefaction, cavitation, and destruction of normal lung architecture, and associated with significant morbidity and mortality. Clinicaly, early presentations may be indistinguishable from uncomplicated pneumonia (pna), with fever, cough, pleuritic chest pain, and dyspnea, which can delay recognition in the emergency department. Differential diagnosis for these symptoms is broad and includes uncomplicated pneumonia, septic emboli, lung abscesses, and pleural effusion. However, patients effected with necrotizing pneumonia often exhibit more severe systemic toxicity, rapid progression of respiratory failure, and hemodynamic instability. In this case report, we …

Wildfires And Emergency Department Respiratory Surge: Brief Review, Systems Forecasting Implications And Recommendations For Research, James Espinosa, Alan Lucerna

Rowan-Virtua Research Day

Background: Wildfire smoke produces abrupt increases in PM2.5 and Air Quality Index (AQI) levels. Event-based and multi-season studies demonstrate short-term increases in asthma-related Emergency Department (ED) visits, with additional evidence supporting increased utilization for broader respiratory disease and chronic lower respiratory disease (including COPD) (Reid et al., 2016; Liu et al., 2015; Stowell et al., 2025; CDC, 2023).

Objective: To synthesize current evidence linking wildfire smoke to ED respiratory surge and to propose a systems forecasting model that translates environmental signals into structured operational stabilization within a complex adaptive system (CAS).

Methods (Review & Model Development): Narrative synthesis of event-based …

Quantification Of Mouse Tracheal Epithelial Cell Differentiation With Cilia Defects, Olivia V. Allen

Honors Thesis

Primary Ciliary Dyskinesia (PCD) is an autosomal recessive disorder that affects 1 in every 7,500 live births. PCD results from motile cilia defects, impairing mucociliary clearance and causing chronic respiratory infections. Our lab studies include three PCD mouse lines — bgh (Spef2), nm1054 (Cfap221), and Cfap54^gt/gt (Cfap54). Prior transcriptomic data led us to hypothesize that PCD mutant mouse tracheal epithelial cells (MTECs) exhibit reduced differentiation into ciliated cells. MTECs from the trachea of the Wild Type (WT) and the PCD mutant mouse lines were cultured at an Air Liquid Interface (ALI) to start …

Signaling Response Of Epinephrine Treated Cards Toxin-Infected Thp-1 Macrophages, Trinity Martinez

Posters - 2026

Aspiration pneumonia is a common mild case of pneumonia, a disease where the lungs are inflamed and filled with fluid, compromising respiration and gas exchange. One common cause of mild pneumonia is bacterial infection via a pathogen known as Mycoplasma pneumoniae. M. pneumoniae causes a variety of respiratory illness- ranging from pharyngitis, tracheobronchitis, mild pneumonia- and in rare cases encephalitis. M. pneumoniae produces the CARDS toxin, which participates in ADP-ribosylation and vacuolization (Kannan et al., 2006)1. The CARDS toxin causes aspiration pneumonia by paralyzing the cilia that lines the respiratory tract. Epinephrine, or Adrenaline- is a hormone that is medically …

Effects Of Mycoplasma Pneumoniae Cards Toxin On Lung Fibroblast Function, Shuri Magdalene

Posters - 2026

Mycoplasma pneumoniae is a common respiratory pathogen whose virulence depends largely on the community-acquired respiratory distress syndrome (CARDS) toxin, a 591-amino-acid ADP-ribosylating protein¹. CARDS toxin induces immune responses²˒³, causes vacuolation in lung epithelial cells, and contributes to the inflammatory and pathological features of pneumonia. IMR-90 fibroblasts. IMR-90 cells are human fetal lung fibroblasts widely used to study responses to inflammatory signals, extracellular matrix production, and lung injury or repair. Rationale. Fibroblasts are key drivers of tissue remodeling and fibrosis during lung injury. Defining how CARDS toxin influences fibroblast programs in inflammation, cell-cycle control, and matrix remodeling²˒³ will clarify how M. …

Hyperglycemia And Mycoplasma Pneumoniae Cards Toxin Impacts On Lung Epithelial And Fibroblast Injury And Recovery, Alejandra Y. Delgado, Naila Villagomez, Shuri Magdalene

Posters - 2026

Mycoplasma pneumoniae CARDS toxin induces cytotoxicity and inflammation in lung epithelial cells²·¹⁰·¹¹, while hyperglycemia independently elevates ROS and disrupts fibroblast repair¹·⁵·⁸, contributing to the heightened respiratory infection severity seen in diabetic patients¹. However, the interaction between hyperglycemic conditions and CARDS toxin-induced lung injury remains unexplored.

This study investigates how increasing high-glucose (HG) pre-conditioning modifies CARDS toxin-induced injury and recovery in A549⁶ and IMR-90⁷ cells compared to normal glucose (NG ≈ 5mM) controls. We hypothesized that increasing glucose pre-conditioning concentrations would produce a dose-dependent increase in CARDS toxin-induced oxidative stress¹² and inflammatory cytokine production¹⁵ in IMR-90 and A549 compared with normal …
