[Penile Flexiflate® Surgitek prosthesis explant and simultaneous three-component hydraulic Titan® Alpha 1 prosthesis implantation, with double incisi…

2010

Introduction and Objectives We treated a 45 years old patient, suffering from diabetes mellitus since childhood, with retinal, neurovascular and kidney complications. In 1988, for erectile dysfunction (ED) resistant to medical injective treatment, the patient underwent ligation of the dorsal vein of the penis without any result. In 1989 a Flexiflate® hydraulic prosthesis was implanted with resolution of ED. In 2005 the patient underwent simultaneous kidney and pancreas transplant with a trans-laparotomic approach for end stage renal disease and diabetes mellitus. In 2009, because of the Flexiflate® Surgitek malfunction, the patient underwent explantation of the Flexiflate® prosthesis and si…

Failure to detect genomic viral sequences in pancreatic tissues from two children with acute-onset diabetes mellitus.

1994

Two cases of fatal, acute-onset, insulin-dependent diabetes mellitus (IDDM) in children were diagnosed. Epidemiologic and serologic studies, as well as histologic analysis of pancreatic tissue in fatal viral infections, support the contention that a viral infection could cause beta cell destruction, leading to IDDM. The presence of nucleic acid sequences from viral agents considered to be potentially diabetogenic, specifically, cytomegalovirus and mumps, rubella, and coxsackie viruses, were investigated in the pancreatic tissues by reverse transcription followed by polymerase chain reaction (RT-PCR) and Southern blot hybridization. Total pancreatic RNAs extracted from five children who died…

Focal Pancreatic Lesions: Role of Contrast-Enhanced Ultrasonography.

2021

The introduction of contrast-enhanced ultrasonography (CEUS) has led to a significant improvement in the diagnostic accuracy of ultrasound in the characterization of a pancreatic mass. CEUS, by using a blood pool contrast agent, can provide dynamic information concerning macro- and micro-circulation of focal lesions and of normal parenchyma, without the use of ionizing radiation. On the basis of personal experience and literature data, the purpose of this article is to describe and discuss CEUS imaging findings of the main solid and cystic pancreatic lesions with varying prevalence.

New Imidazo[2,1-b][1,3,4]Thiadiazole Derivatives Inhibit FAK Phosphorylation and Potentiate the Antiproliferative Effects of Gemcitabine Through Modu…

2020

Background/aim A new class of imidazo[2,1-b][1,3,4]thiadiazole compounds have recently been evaluated as inhibitors of phosphorylation of focal adhesion kinase (FAK) in pancreatic cancer. FAK is overexpressed in mesothelioma and has recently emerged as an interesting target for the treatment of this disease. Materials and methods Ten imidazo[2,1-b][1,3,4]thiadiazole compounds characterized by indole bicycle and a thiophene ring, were evaluated for their cytotoxic activity in two primary cell cultures of peritoneal mesothelioma, MesoII and STO cells. Results Compounds 1a and 1b showed promising antitumor activity with IC50 values in the range of 0.59 to 2.81 μM in both cell lines growing as …

Obese rats exhibit high levels of isoprostanes in acute pancreatitis

2012

s / Pancreatology 12 (2012) 502–597 538 interference of Sam68 and SRSF1 expression cause a partial recovery of drug sensitivity. Conclusions: Our results show that chronic exposure of PDAC cells to gemcitabine leads to selection of a drug-resistant subpopulation overexpressing Sam68 and SRSF1. Importantly, the depletion of these proteins leads to a partial recovery of the sensibility to gemcitabine, suggesting that they may represent suitable molecular-targets to overcome drug resistance in PDAC.

Pancreatic T cell protein-tyrosine phosphatase deficiency ameliorates cerulein-induced acute pancreatitis.

2014

Background Acute pancreatitis (AP) is a common clinical problem whose incidence has been progressively increasing in recent years. Onset of the disease is trigged by intra-acinar cell activation of digestive enzyme zymogens that induce autodigestion, release of pro-inflammatory cytokines and acinar cell injury. T-cell protein tyrosine phosphatase (TCPTP) is implicated in inflammatory signaling but its significance in AP remains unclear. Results In this study we assessed the role of pancreatic TCPTP in cerulein-induced AP. TCPTP expression was increased at the protein and messenger RNA levels in the early phase of AP in mice and rats. To directly determine whether TCPTP may have a causal rol…

Non‐bacterial thrombotic endocarditis in a patient with pancreatic carcinoma

2021

Nonbacterial thrombotic endocarditis (NBTE) is a rare condition that most often accompanies a malignant disease and involves a hypercoagulable state. We report the incidental finding of a rare case of an NBTE affecting the tricuspid valve in a patient with metastatic pancreatic carcinoma complicated by severe venous and arterial thromboembolisms.

Thymidine-dependent Staphylococcus aureus small-colony variants: human pathogens that are relevant not only in cases of cystic fibrosis lung disease.

2008

ABSTRACT We report the isolation of thymidine-dependent small-colony variants (TD-SCVs) of Staphylococcus aureus from unusual infection sites of patients with chronic soft tissue infection, tympanitis, bronchitis, peritonitis, and septicemia. Furthermore, we provide evidence that the essential growth factor for TD-SCVs, i.e., thymidine, and its metabolite dTMP are present in various human specimens.

Donor-derived Strongyloides stercoralis hyperinfection syndrome after simultaneous kidney/pancreas transplantation

2016

Most cases of strongyloidiasis associated with solid organ transplantation have been due to the reactivation of a latent infection in the recipient as a result of the immunosuppressive therapy; however, donor-derived infections are becoming increasingly frequent. The case of a patient who nearly died of a Strongyloides stercoralis hyperinfection after receiving simultaneous kidney/pancreas transplants is described herein. No specific parasitological tests were performed pre-transplantation, despite the fact that both the recipient and the donor originated from endemic areas. Serological analysis of the donor's serum performed retrospectively revealed the origin of the infection, which if it…
