BACKGROUND: Eosinophilic cholangitis (EC) is a rare benign disorder of the biliary tract which can cause biliary obstruction. Similar to other disease processes involving the bile ducts, this disorder can pose a difficult diagnostic challenge as it can mimic cholangiocarcinoma.
METHODS: A systematic search of the scientific literature was carried out using PubMed to access all publications related to EC. Search keywords that were utilized included "eosinophilic cholangitis," "etiology," "treatment," and "obstructive jaundice." Results. Twenty-three cases of EC have been reported. Nineteen patients (82.6%) who presented with EC remain disease-free; 15 of these 19 patients (78.9%) with followup time remain …

Abstract
Background
Sulforaphane (SFN), an isothiocyanate phytochemical present predominantly in cruciferous vegetables such as brussels sprout and broccoli, is considered a promising chemo-preventive agent against cancer. In-vitro exposure to SFN appears to result in the induction of apoptosis and cell-cycle arrest in a variety of tumor types. However, the molecular mechanisms leading to the inhibition of cell cycle progression by SFN are poorly understood in epithelial ovarian cancer cells (EOC). The aim of this study is to understand the signaling mechanisms through which SFN influences the cell growth and proliferation in EOC.
Results
SFN at concentrations of 5 - 20 …

Abstract
Background
We recently reported a lymphatic cerebrospinal fluid (CSF) absorption deficit in a kaolin model of communicating hydrocephalus in rats with ventricular expansion correlating negatively with the magnitude of the impediment to lymphatic function. However, it is possible that CSF drainage was not significantly altered if absorption at other sites compensated for the lymphatic defect. The purpose of this study was to investigate the impact of the lymphatic absorption deficit on global CSF absorption (CSF outflow resistance).
Methods
Kaolin was injected into the basal cisterns of Sprague Dawley rats. The development of hydrocephalus was assessed using magnetic resonance imaging …

Section of Ophthalmology
Blepharophimosis-ptosis-epicanthus inversus syndrome (BPES) is a rare developmental ocular disorder. We report this condition affecting 4 members of a Pakistani family across three generations. A 2-year-old girl was brought to the clinic by her father for the correction of her shortened palpebral fissures. Examination findings were consistent with BPES. The girl's father, paternal grandfather and paternal aunt also had identical features. The distance between the medial canthi of the index case was 30 mm, and the lengths of vertical and horizontal palpebral fissure were 6 mm and 20 mm, respectively. BPES must be considered an important differential diagnosis in patients …

Abstract
Background
CARP-1/CCAR1, a perinuclear phospho-protein, regulates signaling by adriamycin, steroids, or growth factors. However, intracellular events that regulate CARP-1-dependent cell growth are not fully understood.
Results
Here we investigated whether CARP-1 is involved in signaling induced by the protein kinase A inhibitor H89. Treatments of human breast cancer cells with H89 resulted in apoptosis that involved enhanced CARP-1 threonine phosphorylation and expression. Depletion of CARP-1, on the other hand, abrogates apoptosis induced by H89. CARP-1 binds with signal transducer TAZ and over-expression of TAZ inhibits apoptosis by CARP-1. CARP-1 (651-759) interacts with a novel, N-terminal epitope of TAZ. H89 …

Access For Laparoendoscopic Single Site Surgery, Sharona B. Ross, C. Whalen Clark, Connor A. Morton, Alexander S. Rosemurgy
Surgery Faculty Publications
Laparoscopic surgery is the standard of care for many abdominal and pelvic operations and is widely applied today. LESS (Laparo-Endoscopic Single Site) surgery, originally attempted in the 1990s, is an advanced minimally invasive approach that allows laparoscopic operations to be undertaken through a small (<15 mm) incision in the umbilicus, a preexisting scar. The presence of a preexisting scar allows LESS surgery to be essentially scarless, which is the key benefit to LESS operations. Herein, we review our experience with over 500 LESS operations and discuss the key techniques to establishing access to the peritoneal cavity. We review the options for obtaining access, available instrumentation, common challenges and solutions for access. We conclude that LESS surgery is safe and provides outcomes with superior cosmesis relative to conventional laparoscopy. LESS surgery should be embraced, as patient demand is rapidly increasing.

Department of Surgery Faculty Papers
BACKGROUND: Esophageal carcinoma is an aggressive disease that is often treated with neoadjuvant therapy followed by surgical resection. Diabetes mellitus (DM) has been associated with reduced efficacy of chemoradiation (CRT) in other gastrointestinal cancers. The goal of this study was to determine if DM affects response to neoadjuvant CRT in the management of gastroesophageal carcinoma.
METHODS: We retrospectively reviewed the esophageal cancer patient databases and subsequently analyzed those patients who received neoadjuvant CRT followed by surgical resection at two institutions, Thomas Jefferson University (TJUH) and Fox Chase Cancer Center (FCCC). Comparative analyses of rates of pathologic complete response rate (pCR) …

Abstract
Background
A variety of pathways target CDKI p21WAF1/CIP1 expression at transcriptional, post-transcriptional as well as translational levels. We previously found that cell growth suppressing retinoid CD437 enhanced expression of p21WAF1/CIP1 and DNA damage inducible GADD45 proteins in part by elevating their mRNA stability.
Results
Here, we investigated molecular mechanisms of CD437-dependent post-transcriptional regulation of p21WAF1/CIP1 expression. By utilizing MDA-MB-468 HBC cells expressing chimeric rabbit β-globin-p21WAF1/CIP1 transcripts we mapped multiple CD437-responsive sequences located within positions 1195 to 1795 of the 3'-untranslated region of p21WAF1/CIP1 mRNA. Several cytoplasmic proteins present in MDA-MB-468, MCF-7 HBC as well …
