School of Dentistry Faculty Publications

Introduction: The rubber dam has been a standard in endodontic practice for over 140 years, providing critical isolation to prevent microbial contamination during root canal therapy. However, studies indicate that microleakage between the rubber dam and tooth structure may still occur, potentially leading to bacterial infiltration. Various resin-based barriers have been introduced to enhance isolation and minimize leakage. This study aimed to evaluate the efficacy of four resin-based barriers in reducing microleakage during endodontic procedures. Methods: Forty extracted human mandibular molars were selected, stored in distilled water, and standardized for experimental conditions. Standard endodontic access was created, and the mesiobuccal …

School of Medicine Faculty Publications

Epilepsy is a neurological disorder characterized by recurrent, unprovoked seizures, affecting millions worldwide. While anti-seizure medications serve as first-line treatment, approximately one-third of patients develop drug-resistant epilepsy (DRE), necessitating alternative interventions. Deep brain stimulation (DBS) has emerged as a promising therapy for DRE, particularly for patients who are ineligible for resective surgery. DBS involves stereotactic implantation of electrodes into target brain regions, such as the anterior nucleus of the thalamus (ANT), centromedian nucleus (CMT), and hippocampus (HC), to modulate aberrant neural activity and to reduce seizure frequency. Anesthesia plays a critical role in DBS implantation, influencing both patient safety and …

Morphological And Immunohistochemical Support For The Origin Of The Carcinoid Component In Strumal Carcinoids: A Case Report And Literature Review, Yu Liu, Asra Feroze, Liz Yang, Ridin Balakrishnan

School of Medicine Faculty Publications

Strumal carcinoid tumors of the ovary are rare neoplasms composed of an intimate mixture of thyroid and carcinoid tissues. Although various theories regarding their histogenesis have been proposed, evidence confirming the origin of the carcinoid component has been lacking. We report a case of a 40-year-old female with an ovarian strumal carcinoid arising in the background of a mature cystic teratoma. Morphological and immunohistochemical findings support the hypothesis that the carcinoid component originates from the thyroid follicular epithelium, undergoing neuroendocrine differentiation. A single-cell growth pattern was also identified, expanding the known histological spectrum of strumal carcinoids. Our case provides additional …

Supercharged And Delayed Thoracodorsal And Dorsal Intercostal Artery Perforator Flaps For Autologous Breast Reconstruction, Adeem M. Nachabe, Mohammed S. Rais, Mark A. Maier, Hugo St Hilaire, Robert J. Allen

School of Medicine Faculty Publications

In patients seeking total autologous breast reconstruction following mastectomy, prior abdominal surgery can present as a contraindication to utilizing traditional abdominal-based free flaps. The thoracodorsal artery perforator (TDAP) flap has emerged as a suitable alternative, providing adequate tissue and minimal donor site morbidity. This case report demonstrates further improvement to this technique by utilizing the dorsal intercostal artery perforator vessels to supercharge this pedicled flap, along with a surgical delay of the TDAP and dorsal intercostal artery perforator. This adaptation can provide added bulk and improved perfusion to the traditional TDAP-based total autologous breast reconstruction.
