Endovascular Management And The Risk Of Late Failure In The Treatment Of Ureteroarterial Fistulas, George Titomihelakis, Anthony Feghali, Tuong Nguyen, Dawn Salvatore, Paul Dimuzio, Babak Abai

Department of Medicine Faculty Papers

Ureteroarterial fistula (UAF) is a rare and life-threatening source of hematuria. A high index of suspicion is warranted for early diagnosis and timely intervention. Because of high perioperative risk and comorbidities in UAF patients, the endovascular approach has become preferred for repair. Infection can complicate this mode of therapy, and treatment with antibiotics is important. Herein we present five cases of secondary UAFs treated with stent graft alone or stent graft and embolization.

Use Of Gastric Bypass Surgery For The Treatment Of Type 2 Diabetes Mellitus, Kaitlin A. Sanders, Jenna L. Schaffner, Leslie M. Hart, Whitney N. Detillion, Anne Gentry

Pharmacy and Wellness Review

Over the past decade, the incidence of type 2 diabetes mellitus (T2DM) has increased significantly. Evidence has shown that a clear association exists between obesity and diabetes development. This association has inspired researchers to explore bariatric surgery as an option for diabetes management and possible disease reversal. Improvement of T2DM using Roux-En-Y gastric bypass (RYGB) is thought to result from from a combination of weight loss, decreased caloric intake, hormonal changes and rearrangement of the gastrointestinal anatomy. Positive outcomes resulting from the procedure include decreased mortality rates, normalization of HbA1c levels, decreased dependence on diabetic medications, and increased insulin sensitivity. …

Perioperative Use Of Renin-Angiotensin System Inhibitors And Outcomes In Patients Undergoing Cardiac Surgery., Qian Ding, Zugui Zhang, Hong Liu, Huang Nie, Mark Berguson, Jordan E. Goldhammer, Nilas Young, Douglas Boyd, Rohinton Morris, Jianzhong Sun

Department of Anesthesiology Faculty Papers

It remains disputable about perioperative use of renin-angiotensin system inhibitors (RASi) and their outcome effects. This multicenter retrospective cohort study examines association between use of perioperative RASi and outcomes in patients undergoing coronary artery bypass graft and/or valve surgery. After the exclusion, the patients are divided into 2 groups with or without preoperative RASi (PreRASi, n = 8581), or 2 groups with or without postoperative RASi (PostRASi, n = 8130). With using of propensity scores matching to reduce treatment selection bias, the study shows that PreRASi is associated with a significant reduction in postoperative 30-day mortality compared with without one …

Incidence Of Intraocular Lens Exchange After Cataract Surgery, Maram E. A. Abdalla Elsayed, Khabir Ahmad, Abdulelah A. Al-Abdullah, Rizwan Malik, Rajiv Khandekar, Hernan Martinez-Osorio, Marco Mura, Patrik Schatz

Department of Surgery Docs

Intraocular lens (IOL) exchange after cataract surgery is unusual but may be associated with suboptimal visual outcome. The incidence of IOL exchange has not been consistently estimated. Such information is invaluable when counseling patients prior to cataract surgery. We examined the incidence of, and indications and risk factors for, IOL exchange after cataract surgery. We also assessed visual outcome of eyes that had an IOL exchange. A cohort design was used to estimate the incidence of IOL exchange and a case-control design to identify factors associated with it. All phacoemulsification surgeries with IOL (n = 17415 eyes) during 2010-2017 and …

The aim of this study was to evaluate the effects and underlying mechanisms of irisin on malignant growth of pancreatic cancer cells.

Materials and methods: The anti-proliferative effect of irisin was examined using the CCK-8 assay. Irisin-induced apoptosis was determined by the annexin V-FITC/PI staining assay. The effects of irisin on cell migration and invasion were assessed using …

Geriatric Hepatology: The Hepatic Diseases Of The Elderly And Liver Transplant, Shima Ghavimi, Hamed Azimi, Neel Patel, Oleg Shulik

Internal Medicine

Introduction: With the aging US population, chronic liver diseases are becoming more commonly diagnosed in the geriatric population. Advanced age leads to changes in liver blood flow, volume, morphology and normal physiology. This predisposes elderly patients to develop certain chronic liver diseases. Also, the clinical course and management differ in an older patient when compared to a younger patient. Some causes of chronic liver disease in the geriatric population include Hepatitis A, B, C, Non-Alcoholic Fatty liver disease, prolonged alcohol use and inflammation. Many chronic liver diseases are characterized by a slow, indolent course of progression with non-specific symptoms and …

Surgical Stress And Cancer Progression: The Twisted Tango., Zhiwei Chen, Peidong Zhang, Ya Xu, Jiahui Yan, Zixuan Liu, Wayne Bond Lau, Bonnie Lau, Ying Li, Xia Zhao, Yuquan Wei, Shengtao Zhou

Department of Emergency Medicine Faculty Papers

Surgical resection is an important avenue for cancer treatment, which, in most cases, can effectively alleviate the patient symptoms. However, accumulating evidence has documented that surgical resection potentially enhances metastatic seeding of tumor cells. In this review, we revisit the literature on surgical stress, and outline the mechanisms by which surgical stress, including ischemia/reperfusion injury, activation of sympathetic nervous system, inflammation, systemically hypercoagulable state, immune suppression and effects of anesthetic agents, promotes tumor metastasis. We also propose preventive strategies or resolution of tumor metastasis caused by surgical stress.

Pituitary Adenoma With Calcifications: A Case Report, Yakoot Khan, Noor Malik, Saba Iqbal Awan, Syed Hassan Khalid, Altaf Ali Laghari

Section of Neurosurgery

Pituitary adenomas and Rathke’s cleft cyst with calcification are rarely seen and craniopharyngioma still remains the common sellar suprasellar space occupying lesion with calcification. Presence of calcification is reported in pituitary adenoma in only 0.2% to 8% cases. The pituitary adenoma with calcification is a rare radiological finding and it must be distinguished from other lesions of the pituitary gland as the management and prognosis differs significantly. We report a case of a 29-year-old gentleman presented electively with the complaints of deterioration of vision for four months. CT-scan without contrast examination revealed pituitary adenoma with calcification. The patient underwent transsphenoidal …

Optimal Timing And Route Of Nutritional Support After Esophagectomy: A Review Of The Literature., Richard Zheng, Courtney L. Devin, Michael J. Pucci, Adam C. Berger, Ernest L. Rosato, Francesco Palazzo

Department of Surgery Faculty Papers

Some controversy surrounds the postoperative feeding regimen utilized in patients who undergo esophagectomy. Variation in practices during the perioperative period exists including the type of nutrition started, the delivery route, and its timing. Adequate nutrition is essential for this patient population as these patients often present with weight loss and have altered eating patterns after surgery, which can affect their ability to regain or maintain weight. Methods of feeding after an esophagectomy include total parenteral nutrition, nasoduodenal/nasojejunal tube feeding, jejunostomy tube feeding, and oral feeding. Recent evidence suggests that early oral feeding is associated with shorter LOS, faster return of …
