Adrenalectomy For Solitary Metastasis Of Hepatocellular Carcinoma Post Liver Transplantation: Case Report And Literature Review, Imran K. Jalbani, Nazim Syed Muhammad, Usman Tariq Siddiqui, Farahat Abbas

Department of Surgery Docs

Abstract

Liver transplantation (LT) is the treatment of choice for localized hepatocellular carcinoma (HCC) associated with cirrhosis. Extra hepatic metastasis is the most common cause of death in these patients. There is very little evidence regarding the natural history and treatment options for patients developing HCC recurrence after LT. Surgical resection offers a unique opportunity for solitary metastasis. We report a 61 year old male with solitary right adrenal metastasis 15 months post LT which was managed with open adrenalectomy. The patient is alive and disease free 24 months after the surgery. The case, histo-pathological findings and literature review is …

Primary Melanotic Schwannoma With Typical Histology, Usman B. Mahmood, Fazal Wahab Khan, Benish Fatima, Muhammad Usman Tariq, Saulat Hasnain Fatimi

Department of Surgery Docs

Abstract

We present a case of a 17-year male with a soft tissue density spreading from the neural foramina (T3) of the spinal cord and involving the right upper thoracic cavity. We managed the patient through surgical intervention and resected the complete tumor. Gross definition and microscopic findings of the resected tissue revealed the definitive diagnosis of melanotic schwannoma. The histological characteristics in this case were very specific and harbour an important diagnostic clue for this rare disease. Malignant melanoma was ruled out on the basis of histological findings. The patient recovered completely and was healthy on one-year follow-up.

Manufacturer Perspectives On Content Transparency And Material Health In The Us Building Products Industry, Alexandra A. Muller

Open Access Theses

Flawed U.S. federal regulation of chemicals has resulted in a materials market that undervalues human and environmental health in favor of the more traditional attributes of price, performance and aesthetics. In the building products industry, global, dynamic supply chains and proprietary information concerns further complicate the task of assessing the material health of products.

Voluntary material health programs in the green building industry are intended to incentivize the manufacture and selection of safer products by getting companies to gather and assess ingredient, hazard and risk information from their supply chain. Building product manufacturers considered early adopters of the main material …

The Interactive Effects Of Pesticide Exposure And Infectious Disease On Amphibian Hosts, Katherine M. Pochini

Open Access Theses

Natural systems are home to a multitude of natural and anthropogenic stressors, which draw an array of effects on ecological communities. While these effects have been investigated individually, it is important, given the routine co-occurrence of these stressors, to understand their interactive effects. Pesticide exposure and infectious disease are two common, co-occurring stressors that each have documented detrimental effects on species and, as evidence suggests, may have interactive effects. Moreover, existing research suggests that these interactive effects are highly context dependent, eliciting different results based on species, disease agent, toxin, and environment. Given the variability with which species may experience …

Traumatic Posterior Tibial Pseudoaneursym: A Rare Late Complication Repaired Conventionally, Farzad Amiri, Md, Zachary Sanford, Constantinous Constantinou, Md

Marshall Journal of Medicine

Posterior tibial artery pseudoaneurysms are extremely rare. They commonly present as a late complication of trauma or iatrogenic injury. Diagnosis can be elusive. Treatment has been described in the context of open primary repair, endovascular stenting, and coil embolization. There has been increasing interest in the use of endovascular treatment options for this type of injury. If left untreated, pseudoaneurysms can rupture, partially thrombose, expand and cause adjacent local compression and compartment syndrome. The following case presented is of a young gentleman with a posterior tibial pseudoaneurysm incidentally discovered after stepping on glass and the management of his posterior tibial …

Could There Be Light At The End Of The Tunnel? Mesocaval Shunting For Refractory Esophageal Varices In Patients With Contraindications To Transjugular Intrahepatic Portosystemic Shunt., Jessica Davis, Albert K Chun, Marie L Borum

Surgery Faculty Publications

Cirrhotic patients with recurrent variceal bleeds who have failed prior medical and endoscopic therapies and are not transjugular intrahepatic portosystemic shunt candidates face a grim prognosis with limited options. We propose that mesocaval shunting be offered to this group of patients as it has the potential to decrease portal pressures and thus decrease the risk of recurrent variceal bleeding. Mesocaval shunts are stent grafts placed by interventional radiologists between the mesenteric system, most often the superior mesenteric vein, and the inferior vena cava. This allows flow to bypass the congested hepatic system, reducing portal pressures. This technique avoids the general …

Transoral Incisionless Fundoplication: Current Status., Karim Sami Trad

Surgery Faculty Publications

Purpose of review

Transoral incisionless fundoplication (TIF) performed with the EsophyX device (Redmond, Washington, USA) is a totally endoscopic procedure with the objectives to mechanically repair a defective gastroesophageal valve and to reduce small hiatal hernias. The recent publication of randomized controlled trials and long-term follow-up data offers the opportunity to reevaluate this treatment modality and its role in the management of patients with chronic gastroesophageal reflux disease (GERD).

Recent findings

Randomized controlled trials have confirmed the ability of TIF to eliminate troublesome GERD symptoms, heal esophagitis, and improve distal esophageal acid exposure in appropriately selected patient populations. These studies …

In-Vitro Comparison Of Micro-Leakage Between Nanocomposite And Microhybrid Composite In Class V Cavities Treated With The Self-Etch Technique, Syeda Mahvish Hussain, Farhan Raza Khan

Department of Surgery Docs

Abstract

BACKGROUND:

When a light cure composite resin is used to restore a class V lesion, certain stresses are generated at the tooth-restoration interface. If these stresses exceed the bond strength of the restorative material, microscopic gaps are formed which eventually cause micro-leakage at the tooth-restoration interface. The objective of the present study was to compare the micro-leakage values at the tooth-restoration interface using dye penetration method between a Nano filled and a Micro hybrid light cured composite resin in class V cavities using the self-etch technique.

METHODS:

Sixty class V cavities were made coronal to the cemento-enamel junction in …

Objective: The aims were to compare outcome variables in children with gastroesophageal reflux disease (GERD) and one Nissen fundoplication to children with redo fundoplications and define the pediatric redo population. Methods: After IRB approval (#5100277), a case control study was conducted of children younger than 18 years, from two children’s hospitals, with one Nissen fundoplication (control group) or a redo performed between January 1995 and March 2011. Complete data were collected by phone calls to caregivers in December 2012. Only redo operations performed after recurrence of GERD symptoms and wrap herniation into the mediastinum confirmed by contrast radiograph were included. …

Outcomes Of External Repair Of Heartmate Ii™ Lvad Percutaneous Leads, Jay D. Pal, Claudius Mahr, Jason W. Smith, Todd F. Dardas, Jay Pinette, David J. Farrar, Nahush A. Mokadam

The VAD Journal

Background: The HeartMate II Left Ventricular Assist Device (LVAD) receives power via a percutaneous lead connected to an external controller and batteries. At times, this lead can be damaged during normal wear, as well as by traumatic fracture, which may jeopardize the functionality of the LVAD. If there is significant internal damage, surgical replacement of the LVAD is required. However it is possible to repair externally damaged leads by replacing the distal portion of the lead to avoid pump replacement. We report the overall experience and outcomes in patients with external lead repairs.

Methods: A procedure for full …

Cannabinoid Receptor Type-2 Modulates Nociceptive Signaling Molecules In A Model Of Post-Concussion Headache, Jarred M. Stratton, Lan Cheng, Ashley L. Tyburski, Jessica Perino, Melanie B Elliott

Department of Neurosurgery Posters

Abstract

The goal of this study was to investigate the role of the cannabinoid receptor type-2 (CB₂R) in the trigeminal pain pathway in a model of post-concussion headache. Sprague Dawley rats were randomized to receive either a repeated mild closed head injury (CHI) or served as incision controls. Changes in CGRP, nNOS, and IBA-1 were assessed in the trigeminal nucleus caudalis (TNC) and trigeminal ganglia via IHC. A subset of CHI rats received either a cannabinoid receptor type 2 (CB₂R) anti-inflammatory agonist (JWH133), an NSAID (Ketorolac), or vehicle and underwent von Frey testing for trigeminal allodynia. …

Medicare Reimbursement For Total Joint Arthroplasty: The Driving Forces., Eric M. Padegimas, Kushagra Verma, Benjamin Zmistowski, Richard H. Rothman, James J. Purtill, Michael Howley

Department of Orthopaedic Surgery Faculty Papers

BACKGROUND: Total joint arthroplasty is a large and growing part of the U.S. Medicare budget, drawing attention to how much providers are paid for their services. The purpose of this study was to examine the variables that affect total joint arthroplasty reimbursement. Along with standard economic variables, we include unique health-care variables. Given the focus on value in the Affordable Care Act, the model examines the relationship of the quality of care to total joint arthroplasty reimbursement. We hoped to find that reimbursement patterns reward quality and reflect standard economic principles.

METHODS: Multivariable regression was performed to identify variables that …

Outcomes And National Trends For The Surgical Treatment Of Lumbar Spine Trauma., Doniel Drazin, Miriam Nuno, Faris Shweikeh, Alex R. Vaccaro, Eli Baron, Terrence T. Kim, J. Patrick Johnson

Department of Orthopaedic Surgery Faculty Papers

Introduction. Operative treatment of lumbar spine compression fractures includes fusion and/or cement augmentation. Our aim was to evaluate postoperative differences in patients treated surgically with fusion, vertebroplasty, or kyphoplasty. Methods. The Nationwide Inpatient Sample Database search for adult vertebral compression fracture patients treated 2004-2011 identified 102,316 surgical patients: 30.6% underwent spinal fusion, 17.1% underwent kyphoplasty, and 49.9% underwent vertebroplasty. Univariate analysis of patient and hospital characteristics, by treatment, was performed. Multivariable analysis was used to determine factors associated with mortality, nonroutine discharge, complications, and patient safety. Results. Average patient age: fusion (46.2), kyphoplasty (78.5), vertebroplasty (76.7) (p < .0001). Gender, race, household income, hospital-specific characteristics, and insurance differences were found (p ≤ .001). Leading comorbidities were hypertension, osteoporosis, and diabetes. Risks for higher mortality (OR 2.0: CI: 1.6-2.5), nonroutine discharge (OR 1.6, CI: 1.6-1.7), complications (OR 1.1, CI: 1.0-1.1), and safety related events (OR 1.1, CI: 1.0-1.1) rose consistently with increasing age, particularly among fusion patients. Preexisting comorbidities and longer in-hospital length of stay were associated with increased odds of nonroutine discharge, complications, and patient safety. Conclusions. Fusion patients had higher rates of poorer outcomes compared to vertebroplasty and kyphoplasty cohorts. Mortality, nonroutine discharge, complications, and adverse events increased consistently with older age.
