Recurrent coarctation of the aorta in patients with hypoplastic left heart syndrome requires timely intervention to limit ventricular dysfunction and atrioventricular valve regurgitation. Current strategies include catheter-based intervention in adequately sized patients or surgical arch augmentation at the time of a concomitant operation. We report an open-hybrid surgical technique with placement of a balloon-expandable stent that can later be expanded to an adult size as the patient grows. Limiting the arch dissection reduces the risk to the left recurrent laryngeal nerve and shortens anterograde cerebral perfusion time.

Background

Biologic mesh is often used in complex hernia repair, but there has been limited clinical evidence to date to support this practice. The aim of this study was to compare clinical and patient-reported outcomes of biologic versus synthetic mesh for complex open ventral hernia repair (OVHR) at 3 years.

Methods

Patients from a single center, randomized, controlled, pilot trial comparing biologic versus synthetic mesh in complex OVHR were followed for 3 years. The primary outcome focused on major complications, namely mesh infections, hernia recurrences, reoperations, and deaths. Secondary outcomes included surgical site infections, surgical site occurrences, and patient-reported outcomes. …

Androgen Receptor Ubiquitination Links Kctd13 To Genitourinary Tract Defects, Ahmed Chahdi, Carolina Jorgez, Jill A Rosenfeld, Neetu Neetu, Abhishek Seth

Faculty, Staff and Students Publications

The potassium channel tetramerization domain containing 13 (KCTD13) protein is a substrate-specific adapter for cullin3-based E3 ubiquitin ligase. Patients with copy number variants at this locus exhibit genitourinary tract anomalies. In this study, we show that decreased androgen receptor (AR) protein level correlated with increased AR ubiquitination in the testis of Kctd13-deficient mice, suggesting that KCTD13 inhibits AR ubiquitination. KCTD13 increased CUL3-dependent AR ubiquitination but had no effect on CUL3 binding to AR, confirming the role of KCTD13 as an adaptor of CUL3 ligase. Recombinant KCTD13 directly binds to recombinant AR, and the BTB domain of KCTD13 is critical for …

Post-surgical spinal infection occurs in up to 20 % of patients, despite aggressive peri-operative antibiotic treatments. To improve prophylaxis, we have designed and evaluated an ultrasound-activated prophylactic antibiotic release system to combat post-surgical bacterial survival. Polylactic acid (PLA) clips (1 cm³) were 3D-printed with an interior reservoir (0.8 cm³) for carrying drug payload, specifically vancomycin (VAN). Under IACUC approval, clips were surgically implanted into the spines of sheep (n = 9) and swine (n = 2) by removing the spinous process at several levels of the lumbar spine. In the sheep, clips were insonated and the …

A Narrative Review Of Barriers To Utilization Of Surgical Risk Assessment Calculators, Jacob Lahti, Kaiya A. Noe, Abigail Veenstra, Sarah Gallitto, Victoria I. De Leon, Thomas C. Varkey, Nimit Agarwal

Annual Research Symposium

Over the last several decades, it has become the desire of surgical and medical teams to decrease risk levels involved for patients undergoing surgery. However, despite the advent of risk assessment calculators to help physicians obtain more accurate and objective judgements for postoperative complications, these tools are underutilized in standard clinical practices in comparison to other methods of risk assessment. This is likely due at least in part to certain barriers that decrease their functionality and ease of use. This review discusses the major barriers to the utilization of current risk calculators so as to allow for a better understanding …

High-Output Cardiac Failure Caused By Large Coronary Artery Fistulas Treated With Coil Embolization, Nawal Mustafa, Blain Tafaesse, Hajra Nadeem, Muhammad Mustafa

The VAD Journal

There are many causes of high-output cardiac failure. We present a unique case of high-output cardiac failure caused by multiple coronary-to-pulmonary artery (PA) fistulas, which, to our knowledge, is a rare finding that has not been previously researched. The purpose of our case report is to highlight the importance of considering coronary-to-PA fistulas in the differential diagnosis of patients presenting with high-output cardiac failure. Our patient presented to the emergency department with shortness of breath and underwent nuclear stress testing, which, through cardiac catheterization, revealed coronary-to-PA fistulas as the cause of the high-output cardiac failure. These fistulas were successfully treated …

School of Medicine Faculty Publications

Purpose: The carina, located at the bifurcation of the trachea, has been regarded as a part of the trachea. Although clinically useful as an anatomical landmark, studies of its detailed morphology are lacking in the literature. Methods: The distal trachea and left and right main bronchi were harvested from 32 cadavers and the carina studied using microsurgical dissection, endoscopy, micro-CT, and histology. Results: The right bronchial cartilages were most commonly involved in forming the carina (72.41%), and the left bronchial cartilages were the second most commonly involved (37.93%). The carinal cartilages were slightly deviated to the left of midline in …

Estrogen Receptor-Α Ablation Reverses Muscle Fibrosis And Inguinal Hernias, Tanvi Potluri, Tianming You, Ping Yin, John Coon, Jonah J Stulberg, Yang Dai, David J Escobar, Richard L Lieber, Hong Zhao, Serdar E Bulun

Faculty, Staff and Student Publications

Fibrosis of the lower abdominal muscle (LAM) contributes to muscle weakening and inguinal hernia formation, an ailment that affects a noteworthy 50% of men by age 75 and necessitates surgical correction as the singular therapy. Despite its prevalence, the mechanisms driving LAM fibrosis and hernia development remain poorly understood. Using a humanized mouse model that replicates the elevated skeletal muscle tissue estrogen concentrations seen in aging men, we identified estrogen receptor-α (ESR1) as a key driver of LAM fibroblast proliferation, extracellular matrix deposition, and hernia formation. Fibroblast-specific ESR1 ablation effectively prevented muscle fibrosis and herniation, while pharmacological ESR1 inhibition with …

Early Surgical Decompression For The Treatment Of Hourglass-Like Constriction Of The Posterior Interosseus Nerve, Nathan Redlich, Matan Ozery, Adam Haydel, Charles Cush, Rasheed Ahmad

School of Medicine Faculty Publications

Posterior interosseous nerve (PIN) syndrome refers to a rare compressive neuropathy of the PIN resulting in motor dysfunction of the forearm extensor compartment. Often, surgical exploration will reveal extrinsic structures that mechanically compress the nerve. Less frequently, PIN syndrome has been reported with a visible hourglass-like constriction and no identifiable causative adjacent structures. In our report, we describe an adolescent patient with PIN syndrome and associated hourglass-like constriction of the PIN. For diagnosis, we used physical examination, preoperative imaging, nerve studies, and intraoperative findings. To monitor recovery, we performed serial neurological examinations and documented patient-reported functional outcomes. The patient underwent …

Aortoduodenal Syndrome: A Rare Case Of Duodenal Obstruction Due To Endovascular Aneurysm Endoleak., Raksha Adhikari, Parth Patel, Christopher Tait

Rowan-Virtua School of Osteopathic Medicine Departmental Research

Aortoduodenal syndrome results from expansion of an abdominal aortic aneurysm, leading to symptoms of upper gastrointestinal obstruction. Endovascular aneurysm repair of large or symptomatic aortic aneurysms has become an important treatment modality for patients with abdominal aortic aneurysm. However, a large proportion of these grafts are complicated by endoleaks that can lead to a spectrum of significant symptoms. We present a case of rapidly worsening gastrointestinal obstructive symptoms in a patient with an already repaired aortic stent graft and a solitary kidney, found to be due to a type III endoleak that improved after emergent repeat endovascular aneurysm repair.

Spectrum Of Venous Thromboembolism In Adult Patients With Ulcerative Colitis In Pakistan: A Single Center Retrospective Study, Masood Muhammad Karim, , Hafsa Shaikh, Faisal Wasim Ismail

Department of Medicine

Background: Patients with inflammatory bowel disease are at a 2-8-fold higher risk of developing venous thromboembolism (VTE) as compared to the general population. Although the exact pathogenesis is unclear, the literature suggests that increased risk of thromboembolic events in such patients occurs as a result of increased coagulation factors, inflammatory cytokines, and reduction in anticoagulants leading to a prothrombotic state.
Aim: To assess the prevalence, risk factors, management, and outcome of ulcerative colitis (UC) patients who develop VTE.
Methods: This was a retrospective chart review done in The Gastroenterology Department of The Aga Khan University Hospital. Data was collected from …
