Co-existence of Double Gallbladder and Choledochal Cyst in a Single Patient.

Additional anatomical structures are rare but can be mistaken for other conditions, causing misdiagnoses and poor outcomes for patients. The presence of concurrent anomalies within the extra structures further complicates a rare situation. We present a case of a patient with two gallbladders and a choledochal cyst diagnosed via radiography and confirmed by exploratory laparotomy.

A novel synthetic human insulin super promoter for targeting PDX-1-expressing pancreatic cancer.

Our previous studies have shown that a rat insulin promoter II fragment (RIP) was used to effectively target pancreatic adenocarcinoma (PDAC) and insulinoma that over-express pancreatic and duodenal homeobox-1 (PDX-1). To enhance the activity and specificity of the human insulin promoter, we engineered a synthetic human insulin super-promoter (SHIP). Reporter assay demonstrated that SHIP1 was the most powerful promoter among all of the SHIPs and had far greater activity than the endogenous human insulin promoters and RIP in PDAC expressing PDX-1.

Impact of geriatric consultations on clinical outcomes of elderly trauma patients: A retrospective analysis.

Introduction: The elderly account for a large proportion of morbidity and mortality secondary to trauma, despite lower-energy mechanisms of injury and fewer trauma admissions. The benefit of geriatric trauma consultation services (GTCS) to this population remains unclear.

Methods: We performed a retrospective cohort analysis of a GTCS, which was established in January 2015.

The effect anticoagulation status on geriatric fall trauma patients.

Background: This research study aims to identify the effect of anticoagulation status on hospital course, complications, and outcomes among geriatric fall trauma patients.

Methods: The study design is a retrospective cohort study, looking at fall trauma among patients aged 60 to 80 years from 2009 to 2013 at a university hospital in the United States. The statistical analysis, conducted with SPSS software with a threshold for statistical significance of P < .

Bmi1 enhances tumorigenicity and cancer stem cell function in pancreatic adenocarcinoma.

Background: Bmi1 is an integral component of the Polycomb Repressive Complex 1 (PRC1) and is involved in the pathogenesis of multiple cancers. It also plays a key role in the functioning of endogenous stem cells and cancer stem cells. Previous work implicated a role for cancer stem cells in the pathogenesis of pancreatic cancer.

Long-term follow-up of patients with incidentally discovered pancreatic cystic neoplasms evaluated by endoscopic ultrasound.

Background: The management of incidental pancreatic cysts is not well established because of lack of information on their natural history. International Consensus Guidelines advocate observation of asymptomatic patients with small lesions, despite limited data to support this approach.

Methods: To characterize clinical outcomes in a cohort of asymptomatic patients with incidental pancreatic cysts who underwent endoscopic ultrasound (EUS) evaluation+/-fine needle aspiration (FNA).

Oncogenic function of ATDC in pancreatic cancer through Wnt pathway activation and beta-catenin stabilization.

Pancreatic cancer is a deadly disease characterized by late diagnosis and resistance to therapy. Much progress has been made in defining gene defects in pancreatic cancer, but a full accounting of its molecular pathogenesis remains to be provided. Here, we show that expression of the ataxia-telangiectasia group D complementing gene (ATDC), also called TRIM29, is elevated in most invasive pancreatic cancers and pancreatic cancer precursor lesions.

Early urologic complications after pediatric renal transplant: a single-center experience.

Background: Urologic complications cause substantial morbidity in the pediatric population after renal transplantation, but their impact on graft survival and transplant costs is poorly understood. In this retrospective review, we evaluated the records of all pediatric renal transplant recipients at our center from 1995 to 2004.

Methods: Patient demographics, presence of urinary leak, stricture, compression, or vesicoureteral reflux, and hospital costs were analyzed.

Probing pancreatic disease using tissue optical spectroscopy.

Pancreatic adenocarcinoma, one of the leading causes of cancer death in the United States, has a five-year survival rate of only 4%. Present detection methods do not provide accurate diagnosis in the disease's early stages. To investigate whether optical spectroscopy could potentially aid in early diagnosis and improve survival rates, reflectance and fluorescence spectroscopies were employed for the first time in a limited pilot study to probe freshly excised human pancreatic tissues (normal, pancreatitis, and adenocarcinoma) and in vivo human pancreatic cancer xenografts in nude mice.

Biliary complications following liver transplantation in the model for end-stage liver disease era: effect of donor, recipient, and technical factors.

Biliary complications remain a significant problem following liver transplantation in the Model for End-Stage Liver Disease (MELD) era. We hypothesized that donor, recipient, and technical variables may differentially affect anastomotic biliary complications in MELD era liver transplants. We reviewed 256 deceased donor liver transplants after the institution of MELD at our center and evaluated these variables' association with anastomotic biliary complications.

Total pancreatectomy: indications, operative technique, and postoperative sequelae.

Total pancreatectomy has been used to treat both benign and malignant disease of the pancreas, but its use has been limited by concerns about management of the a-pancreatic state with its attendant total endocrine and exocrine insufficiency. Here, we review the indications for total pancreatectomy, operative technique, and improvements in the postoperative management of patients. Total pancreatectomy remains a viable option in the treatment of intractable pain associated with chronic pancreatitis, multicentric or extensive neuroendocrine tumors, patients with familial pancreatic cancer with premalignant lesions, and in patients with intraductal papillary mucinous neoplasia with diffuse ductal involvement or invasive disease.

Identification of pancreatic cancer stem cells.

Emerging evidence has suggested that the capability of a tumor to grow and propagate is dependent on a small subset of cells within a tumor, termed cancer stem cells. Although data have been provided to support this theory in human blood, brain, and breast cancers, the identity of pancreatic cancer stem cells has not been determined. Using a xenograft model in which primary human pancreatic adenocarcinomas were grown in immunocompromised mice, we identified a highly tumorigenic subpopulation of pancreatic cancer cells expressing the cell surface markers CD44, CD24, and epithelial-specific antigen (ESA).

Comparative serum glycoproteomics using lectin selected sialic acid glycoproteins with mass spectrometric analysis: application to pancreatic cancer serum.

A strategy is developed in this study for identifying sialylated glycoprotein markers in human cancer serum. This method consists of three steps: lectin affinity selection, a liquid separation and characterization of the glycoprotein markers using mass spectrometry. In this work, we use three different lectins (Wheat Germ Agglutinin, (WGA) Elderberry lectin,(SNA), Maackia amurensis lectin, (MAL)) to extract sialylated glycoproteins from normal and cancer serum.
