Dextrocardia With Situs Inversus Totalis: Coronary Artery Bypass Grafting, Salila Hashmi, Mariam Anis, Umer Darr

Section of Cardiothoracic Surgery

Dextrocardia with situs inversus is a rare congenital abnormality involving a left-handed mal rotation of the visceral organs. The incidence of coronary artery disease is the same as that in the general population. Performing coronary artery bypass surgery on patients with dextrocardia poses a more challenging task. It is recommended that the right internal mammary artery be the first choice of graft for the anterior descending artery for a "situs inversus" situation. We report 2 cases of patients with Dextrocardia who developed coronary artery disease and underwent coronary artery bypass grafting. Also mentioned is the slight difference in our technique.

BACKGROUND: One-fifth of patients with seemingly 'curable' pancreatic ductal adenocarcinoma (PDA) experience an early recurrence and death, receiving no definable benefit from a major operation. Some patients with advanced stage tumors are deemed 'unresectable' by conventional staging criteria (e.g. liver metastasis), yet progress slowly. Effective biomarkers that stratify PDA based on biologic behavior are needed. To help researchers sort through the maze of biomarker data, a compendium of ∼2500 published candidate biomarkers in PDA was compiled (PLoS Med, 2009. 6(4) p. e1000046).

METHODS AND FINDINGS: Building on this compendium, we constructed a survival tissue microarray (termed s-TMA) comprised of short-term …

Department of Surgery Faculty Papers

BACKGROUND: Where population coverage is limited, the exclusive use of Cancer Registries might limit ascertainment of incident cancer cases. We explored the potentials of Nationwide hospital discharge records (NHDRs) to capture incident breast cancer cases in Italy.

METHODS: We analyzed NHDRs for mastectomies and quadrantectomies performed between 2001 and 2008. The average annual percentage change (AAPC) and related 95% Confidence Interval (CI) in the actual number of mastectomies and quadrantectomies performed during the study period were computed for the full sample and for subgroups defined by age, surgical procedure, macro-area and singular Region. Re-admissions of the same patients were separately …

Sigmoid Volvulus In Pregnancy And Puerperium: A Surgical And Obstetric Catastrophe Report Of A Case And Review Of The World Literature, Muhammad R. Khan, Sameer Ur Rehman

Department of Surgery Docs

Sigmoid volvulus is a rare surgical complication occurring in pregnancy and puerperium. Only 84 cases of sigmoid volvulus in pregnancy have been reported in the English literature so far. We have reviewed the available literature on this subject and present another case recently managed at our institution. The available literature suggests that over the years, there has been an improvement in the maternal and fetal outcome for this critical condition, but delay in presentation and a further delay in diagnosis remain a challenge for the treating physicians. Our patient was a 30-week pregnant lady, who presented late with 6days history …

Kimmel Cancer Center Faculty Papers

INTRODUCTION:

The incidence of melanoma is dramatically increasing worldwide. We hypothesized that the ratio of metastatic to examined lymph node ratio (LNR) would be the most important prognostic factor for stage III patients.

METHODS:

We retrospectively reviewed our institutional database of melanoma patients and identified 168 patients who underwent lymph node dissection (LND) for stage III disease between 1993 and 2007. Patients were divided into three groups based on LNR (≤10%, n = 93; 10-≤25%, n = 45; and >25%, n = 30). Univariate and multivariate analysis was performed using Cox proportional hazards model.

RESULTS:

The median survival time of …

She’S A Survivor: Post-Operative Counseling And Its Importance To The Recovery Of A Woman Victimized By Female Genital Mutilation, Jacent Wamala

McNair Poster Presentations

The prevalence of Female Genital Mutilation and the difficulty in preventing its practice call for a fresh way of resolving the problem. As the availability of medical professionals equipped with the ability to correct clitoral mutilation grows, there is also an increasing need for professionals that can help the victims after the reconstructive surgery. Post-operative therapy for victims that have opted to receive reconstructive surgery is necessary in order to fully recover. Furthermore, more research in this area is needed to support the findings of this review and will fill the physical and emotional gap exhibited in prior studies related …

The Genetics Of Neuroendocrine Prostate Cancers: A Review Of Current And Emerging Candidates, M Hammad Ather, Tahmeena Siddiqui

Department of Surgery Docs

Prostate cancer (PC) displays a strong familial link and genetic factors; genes regulating inflammation may have a pivotal role in the disease. Epigenetic changes control chromosomal integrity, gene functions, and, ultimately, carcinogenesis. The most widely studied epigenetic event in PC is aberrant DNA methylation (hypo- and hypermethylation); besides this, chromatin remodeling and micro RNA (miRNA) are other studied alterations in PC. These all lead to genomic instability and inappropriate gene expression. Causative dysfunction of histone modifying enzymes results in generic and locus-specific changes in chromatin remodeling. miRNA deregulation also contributes to prostate carcinogenesis, including interference with androgen-receptor signaling and apoptosis. …

Primary Closure Without Diversion In Management Of Operative Blunt Duodenal Trauma In Children, Katherine Smiley, Tiffany Wright, Sean Skinner, Joseph A. Iocono, John M. Draus

Surgery Faculty Publications

Background. Operative blunt duodenal trauma is rare in pediatric patients. Management is controversial with some recommending pyloric exclusion for complex cases. We hypothesized that primary closure without diversion may be safe even in complex (Grade II-III) injuries. Methods. A retrospective review of the American College of Surgeons' Trauma Center database for the years 2003-2011 was performed to identify operative blunt duodenal trauma at our Level 1 Pediatric Trauma Center. Inclusion criteria included ages < 14 years and duodenal injury requiring operative intervention. Duodenal hematomas not requiring intervention and other small bowel injuries were excluded. Results. A total of 3,283 hospital records were reviewed. Forty patients with operative hollow viscous injuries and seven with operative duodenal injuries were identified. …

Correlates Of Morbidity And Mortality In Severe Necrotizing Pancreatitis, K. M. Pal, Pashtoon Murtaza Kasi, Mohammad Tayyeb, S. M. Faisal Mosharraf, Zafar Fatmi

Community Health Sciences

Acute severe pancreatitis is associated with a high morbidity and mortality and frequently is accompanied by underlying pancreatic parenchymal necrosis. Patients with pancreatic necrosis must be identified, because the morbidity and mortality rate in this subgroup is much higher. Our objective was to compare the clinical outcomes of these patients based on the degree of pancreatic necrosis. A total of 35 patients were noted to have pancreatic necrosis. These were divided into 2 groups based on extent of necrosis: group A had less than 50% necrosis and group B had more than 50% necrosis. The rate of mortality (5% versus …

Right Ventricular Rupture And Tamponade Caused By Malposition Of The Avalon Cannula For Venovenous Extracorporeal Membrane Oxygenation., Hitoshi Hirose, Kentaro Yamane, Gregary D. Marhefka, Nicholas C. Cavarocchi

Department of Surgery Faculty Papers

Placement of the Avalon Elite bicaval dual lumen cannula for venovenous extracorporeal membrane oxygenation (VV-ECMO) via the internal jugular vein requires precise positioning of the cannula tip in the inferior vena cava with echocardiography or fluoroscopy guidance. Correct guidewire placement is clearly the key first step in assuring proper advancement of the cannula. We report a case of unexpected wire migration into the right ventricle at the time of final cannula advancement, resulting in right ventricular rupture and tamponade. Transesophageal echocardiography is an important monitoring modality for appropriate placement of the VV-ECMO guidewire and Avalon cannula, and in particular, for …
