Beyond Drainage: Can Pleural Effusion Naturally Tamponade Tumor Hemorrhage? Literature Review Of Hypotheses For Possible Mechanisms, Pratyush Kumar, Kumar Abhishek, Pankti Shah, Amelia Goslin, Archana Machavarapu, Catherine Joyce, Michael J. Waxman, Kari Nilsen

HCA Healthcare Journal of Medicine

Background

Malignant pleural effusion (MPE) is a common complication of advanced lung cancer and is typically treated with therapeutic drainage to relieve symptoms. Although this is a well-established palliative approach, removing pleural fluid—especially in cases of necrotic or post-radiation tumors—may disturb the fragile pressure balance within the thoracic cavity. The question of whether pleural effusion can act as a natural tamponade against tumor-related vascular fragility has not been thoroughly investigated.

Case Presentation

We report a case of a 49-year-old man with stage IIIB non–small cell lung cancer (NSCLC) who experienced a catastrophic hemorrhage shortly after pleural fluid removal via a …


From Molars To Bronchus; The Tale Of An Aspirated Dental Instrument, Yisroel Grabie, Sudeep Acharya, Fasih Sami Siddiqui, Gabriel A. Chavez Reyna, Michel Chalhoub Apr 2025

From Molars To Bronchus; The Tale Of An Aspirated Dental Instrument, Yisroel Grabie, Sudeep Acharya, Fasih Sami Siddiqui, Gabriel A. Chavez Reyna, Michel Chalhoub

HCA Healthcare Journal of Medicine

Background

Aspiration of dental instruments is a rare event that carries potentially serious complications when it occurs, especially in older patients, where protective reflexes are diminished. Clinical management may be difficult because of the risk of granulation tissue and different retrieval strategies according to the object’s characteristics. In this report, we describe the case of an 84-year-old man who aspirated a dental bur during a routine dental procedure, necessitating immediate intervention. Timely and precise management was essential to avert severe complications.

Case Presentation

During a routine dental procedure, an 84-year-old man aspirated a bud-shaped cross-cut carbide dental bur. Despite initial …


Utility Of Incorporating Radiological Findings Of Right Heart Strain In Patients With Acute Pulmonary Embolism For Risk Stratification Of Adverse Outcomes: A Retrospective Analysis, Joshua Amaya, Sameer Allahabadi, Daniel L.

Utility Of Incorporating Radiological Findings Of Right Heart Strain In Patients With Acute Pulmonary Embolism For Risk Stratification Of Adverse Outcomes: A Retrospective Analysis, Joshua Amaya, Sameer Allahabadi, Daniel L.

HCA Healthcare Journal of Medicine

Background

Right heart (RH) strain in the setting of pulmonary embolisms can significantly increase the risk of mortality. Thus, screening for risk of complications in these patients is crucial. The goal of our study was to assess the strength of specific diagnostic findings of RH strain for predicting adverse outcomes including mortality, hospital length of stay, and the requirement of advanced interventions.

Methods

A single-center, retrospective cohort study of 81 patients diagnosed with acute pulmonary embolism with RH strain on computed tomography pulmonary angiogram (CTPA) from September 12, 2019, to August 30, 2023. Data were collected on patient computed tomography …


The Black Fungus: A Rare Case Of Pulmonary Mucormycosis, Stephanie Wong, Elsa Lesley Tchouambou Pougoue, Joanna Polanco, Betty Kirimi, Choudhry Poonam Feb 2025

The Black Fungus: A Rare Case Of Pulmonary Mucormycosis, Stephanie Wong, Elsa Lesley Tchouambou Pougoue, Joanna Polanco, Betty Kirimi, Choudhry Poonam

HCA Healthcare Journal of Medicine

Background

Mucormycosis, commonly known as the "black fungus," is a severe infection affecting multiple organ systems, including the skin, brain, lungs, and gastrointestinal tract. This case report is focused on pulmonary mucormycosis, which is frequently observed in organ transplant recipients. Diagnostic challenges arise from nonspecific symptoms.

Case Presentation

Our case involved a 61-year-old male with a history of renal transplantation. The patient initially presented with a persistent cough and bloody sputum and was treated unsuccessfully for a presumed fungal infection. A lung biopsy confirmed pulmonary mucormycosis, emphasizing the heightened vulnerability of immunocompromised individuals.

Conclusion

This case highlights the intricate nature …


Acute Exacerbation Of Idiopathic Pulmonary Fibrosis In The Setting Of Acute Eosinophilic Pneumonia, Duncan A. Mckinney, Noah R. Kosnik, Shahzeib Syed, Gretchen Junko Feb 2025

Acute Exacerbation Of Idiopathic Pulmonary Fibrosis In The Setting Of Acute Eosinophilic Pneumonia, Duncan A. Mckinney, Noah R. Kosnik, Shahzeib Syed, Gretchen Junko

HCA Healthcare Journal of Medicine

Idiopathic pulmonary fibrosis (IPF) is a progressive disease characterized by gradual destruction and replacement of pulmonary parenchyma with fibrous tissue, which occurs in conjunction with chronic inflammation. It is often considered a prototypical interstitial lung disease and is both the most prevalent and perhaps the most dangerous in that family. Although the disease is uncommon in the general population, its prevalence increases with age and is typically diagnosed around the age of 65. This does not preclude the development of IPF in younger individuals, and the mean survival is 2 to 5 years post-diagnosis regardless of age. Contemporary studies have …


A Rare Case Of C3 Glomerulonephritis Presenting As Pulmonary Renal Syndrome, Gerardo Mederos, Harsh Patel, Menalee Hapuarachchi, Machaiah Madhrira, Ranjit Nair, Dana Ciobanu Dec 2020

A Rare Case Of C3 Glomerulonephritis Presenting As Pulmonary Renal Syndrome, Gerardo Mederos, Harsh Patel, Menalee Hapuarachchi, Machaiah Madhrira, Ranjit Nair, Dana Ciobanu

HCA Healthcare Journal of Medicine

C3 glomerulonephritis (C3GN) is a rare disease that falls under the umbrella of C3 glomerulopathy (C3G). Classic manifestations of C3G include acute renal failure, proteinuria, and hematuria. In some cases, extrarenal manifestations can include ocular drusen. Until recent reports, C3G manifesting with pulmonary symptoms has not been reported. In this report, we describe a patient that initially presented with hemoptysis and acute renal failure, eventually leading to a diagnosis of pulmonary renal syndrome. Renal biopsy showed C3GN. The patient’s symptoms improved with pulse dose steroids, plasmapheresis and mycophenolate mofetil. C3G presenting with pulmonary symptoms is rare. Further research is needed …


Innovative Conservation Of Inhaled Medication Devices During The Covid-19 Pandemic Through A Canister Reassignment Process, Mandelin K. Cooper, L. Hayley Burgess, Karla Miller, Theresa Baltz, Julia Moody, Elizabeth Wiggins, Jeffrey Guy Nov 2020

Innovative Conservation Of Inhaled Medication Devices During The Covid-19 Pandemic Through A Canister Reassignment Process, Mandelin K. Cooper, L. Hayley Burgess, Karla Miller, Theresa Baltz, Julia Moody, Elizabeth Wiggins, Jeffrey Guy

HCA Healthcare Journal of Medicine

Background: The ideal practice for patients requiring metered-dose inhalers (MDI) with coronavirus disease 2019 (COVID-19) is to use patient specific MDIs. However, this practice may not be possible during a time of increased usage throughout the country and limited availability of the medication. Nebulized medications are a concern due to the potential for aerosolized virus and increased exposure for health care workers. An alternative program of canister reassignment is proposed to address concerns for infection prevention, cross-contamination of MDI canisters and the shortage of MDI’s due to the COVID-19 pandemic.

Methods: A comprehensive MDI canister reassignment process was developed for …
