Surgical Outcomes Of Hidradenitis Suppurativa Excision: Factors Impacting Wound Healing Time, Christina Huang, Scott H. Koeneman, Sherry Yang, Sami Tannour

Department of Surgery Faculty Papers

Hidradenitis suppurativa (HS) can be treated surgically to excise recurrent and recalcitrant regions of disease activity. However, surgical outcomes are highly variable depending on closure method, concomitant medical management and area of excision. In this study, we aim to characterise the healing courses from HS excision in a case series. To reduce operator variability, we opted to conduct a case series from a single surgeon. Surgeries conducted from June 2024-December 2025 by surgeon S.T. were included, and the postoperative course was followed until February 2026. Surgical details and postoperative course for 34 sites of HS across 20 patients were analysed. …

Cryoneurolysis Of Auriculotemporal Nerve For Treatment Of Otalgia, Nikit Patel, Shireen Rabiei, Daniel Moon, Yevgeniya Sergeyenko

Moss-Magee Rehabilitation Papers

Otalgia in adults is often secondary to non-otologic pathology, particularly with normal otoscopic examination. Auriculotemporal neuralgia (ATN) is a rare and overlooked cause of secondary otalgia. We present a case of an Army veteran with chronic right otalgia and dizziness following blast-related mild traumatic brain injury who was initially diagnosed with vestibular migraine. Despite significant improvement in headache symptoms with migraine-directed preventive and abortive treatments, otalgia persisted. Auriculotemporal nerve block produced complete but short-lived pain relief, confirming ATN. Cryoneurolysis of the auriculotemporal nerve resulted in complete resolution of otalgia for 2-3 months after first and second treatments. However, transient worsening …

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.

Case Report: Primary Appendiceal Cancer Presenting As Acute Appendicitis, Armeet Singh, Wayne Tamaska, James Espinosa, Alan Lucerna

Rowan-Virtua Research Day

We report a case of a 46‐year‐old male who presented to the emergency department with right lower quadrant abdominal pain and was initially suspected to have acute appendicitis. Further evaluation and surgical pathology revealed primary appendiceal adenocarcinoma. Appendiceal cancer is rare and often presents with nonspecific symptoms that mimic common abdominal conditions such as appendicitis or diverticulitis. Early diagnosis can be challenging, and many cases are discovered incidentally during surgery or imaging for suspected appendicitis. This case highlights the importance of maintaining a broad differential diagnosis for right lower quadrant pain.

Extraparotid Warthin Tumor Presenting As A Cervical Lymph Node Mass: A Case Report., Kristen E. Bowman, Colin Bashline, Konstantinos C. Mantzios, Jack Kelly, David Maki, David Webb

Marshall Journal of Medicine

A Warthin tumor is a salivary gland neoplasm that arises in the parotid gland which is frequently benign. This case study presents a rare instance of a Warthin tumor occurring in an extraparotid location; specifically, within the left-sided cervical lymph nodes of a 64-year-old male patient. The patient initially presented with fluctuating cervical adenopathy. Although an initial ultrasound-guided biopsy was inconclusive,  a computed tomography (CT) scan revealed a well-demarcated, heterogeneous lesion in an atypical location between the parotid gland and the sternocleidomastoid muscle. Surgical excision of the mass was performed and the specimen was sent to pathology for further analysis. …

Biomechanical Effects Of Bilateral Torsion And Skeletal Fusion: A Case Study, Linnéa Forbes

Honors Projects

As part of both a personal endeavor and an academic project, I have investigated the aetiology and treatment of seemingly idiopathic and debilitating leg pain in a patient over the past 10 years. Via collaboration with medical professionals at Cincinnati Children’s Hospital, Cincinnati Premier Physical Therapy, and Cincinnati Women’s TriHealth, I have identified sources of pain at the anatomical level. The combination of internal femoral torsion, external tibial torsion, pes planus, and bony fusions appear to be major perpetuators of the pain. An effective treatment continues to be evasive. To date, I have attempted to find answers through genetic approaches, …

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. …

Transcranial Alternating Current Stimulation As An Adjuvant For Nonfluent Aphasia: A Proof-Of-Concept Study, Lynsey M. Keator, Lisa Johnson, Roger Newman-Norlund, Kyler Spell, Samaneh Nemati, Leigh Ann Spell, Dirk B. Den Ouden, Christopher Rorden, Julius Fridriksson

Department of Speech-Language Pathology Faculty Papers

Effective rehabilitation tools are essential for improving language outcomes in chronic aphasia. Speech entrainment is a behavioral treatment that has shown promise in enhancing speech output in nonfluent aphasia, potentially by acting as an external mechanism to synchronize anterior and posterior language regions in the left hemisphere. Transcranial alternating current stimulation has been hypothesized to enhance functional connectivity between brain regions by amplifying endogenous oscillations. This proof-of-concept study explored whether high-definition tACS (HD-tACS) could improve speech fluency in nonfluent aphasia when paired with speech entrainment. In a double-blind, pseudorandomized study, 1 mA of HD-tACS at 7 Hz was applied to …
