Congenital hyperinsulinism (CHI) is the most common cause of persistent hypoglycaemia in childhood (Horm Res 70:65-72, 2008; J Clin Endocr Metab 93:869-875, 2008). 18-Fluoro-L-dihydroxy-phenylalanine (18F-DOPA) positron emission tomography (PET) can detect areas of increased activity in the pancreas and may differentiate focal from diffuse CHI (J Clin Endocr Metab 93:869-875, 2008; Radiology 253:216-222, 2009). We here report the case of a girl who complained of recurrent episodes of severe hypoglycaemia despite previous partial pancreatectomy...

Adoptive therapy with chimeric antigen receptor (CAR)-redirected T cells has achieved remarkable efficacy in the treatment of hematopoietic malignancies. However, eradicating large solid tumors in advanced stages of the disease remains challenging. We explored augmentation of the anti-tumor immune reaction by establishing an acute inflammatory reaction. Systematic screening indicates that IL-18 polarizes CAR T cells toward T-bethigh FoxO1low effectors with an acute inflammatory response. CAR T cells engineered with inducible IL-18 release exhibited superior activity against large pancreatic and lung tumors that were refractory to CAR T cells without cytokines...

BACKGROUND: Pancreatic schwannoma is a rare tumor. Preoperative diagnosis of pancreatic schwannoma is challenging due to its tendency to mimic other lesions of the pancreas. We describe a case of pancreatic schwannoma and present a review of the cases currently reported in the English literature to identify characteristics of pancreatic schwannoma on imaging. CASE PRESENTATION: A 53-year-old male presented with a history of intermittent periumbilical abdominal pain and lower back pain for 1 week...

The Keap1-Nrf2 system contributes to the maintenance of homeostasis by regulating oxidative stress responses in normal tissues and organs, and is exploited in various cancers for proliferation, survival and acquisition of therapy resistance. Pancreatic cancer remains one of the intractable cancers, despite the improved clinical outcomes of other types of cancer, due to its invasive and refractory nature to therapeutic intervention. The current study aimed to clarify the contribution of Nrf2 to pancreatic carcinogenesis using a pancreas-specific mutant K-ras and p53 (KPC) mouse model...

Pseudomesotheliomatous carcinoma is a malignant tumor that extends along the pleura mimicking malignant mesothelioma. An 81-year-old male patient presented to our hospital with epigastralgia, and abdominal computed tomography (CT) showed a 36-mm tumor in the pancreatic tail. The laboratory data revealed a high leukocyte count (>44 000/μL). Chest CT showed left pleural thickening with pleural effusion. The cancer showed a poor response to chemotherapy, and the patient died of respiratory failure at 5 months after the onset of disease...

Multiple endocrine neoplasia type 1 syndrome can feature pancreatic neuroendocrine lesions that have the potential to degenerate into malignancies (pancreatic neuroendocrine tumors [PNETs]). Resection is required in selected cases and aims to cure patients and to prevent metastasis. Preoperative imaging is important to assess the number, size, and location of PNETs. However, sensitivity of preoperative imaging modalities to detect small lesions can be rather disappointing. This makes intraoperative reassessment of the pancreas crucial...

Accumulation of advanced glycation end products (AGEs) contributes to ageing and age-related diseases, especially type 2 diabetes. The NLRP3 inflammasome, as a vital component of the innate immune system, is implicated in the pathogenesis of type 2 diabetes. However, the role of the NLRP3 inflammasome in AGE-induced pancreatic islet damage remains largely unclear. Results showed that administration of AGEs (120 mg/kg for 6 weeks) in C57BL/6J mice induced an abnormal response to glucose (as measured by glucose tolerance and insulin release), pancreatic β-cell ultrastructural lesion, and cell death...

Objectives: To investigate the effects of region of interest (ROI) sizes on apparent diffusion coefficient (ADC) measurements for the differentiation of normal pancreas (NP), pancreatic ductal adenocarcinoma (PDAC) and mass-forming chronic pancreatitis (MFCP). Results: There were no significant differences for the mean ADCs measured by 12 different-size ROIs for MFCP, or PDAC and NP (P = 0.858-1.0). With the increase of ROI size (≥ 55 mm2), ADCs of PDAC were significantly lower than those of NP (all P < 0...

Introduction Central venous catheterisation is an essential component of patient care in hospital. A forgotten complete guide-wire is a rare complication, although the reported incidence has increased rapidly over the last decade. Case report We report a 72-year-old man with a complete guide-wire inadvertently overlooked during catheter insertion. A central venous catheter had been inserted for total parental nutrition during treatment for pancreatitis. Five years later, the patient was readmitted with a painful lesion on his neck and the sensation of a sharp object under his skin...

Efforts for the early diagnosis of the pancreatic ductal adenocarcinoma (PDAC) have recently been driven to one of the precursor lesions, namely intraductal papillary mucinous neoplasm of the pancreas (IPMN). Only a few studies have focused on IPMN molecular biology and its overall progression to cancer. Therefore, IPMN lacks comprehensive characterization which makes its clinical management controversial. In this study, we characterized plasma proteins in the presence of IPMNs in comparison to healthy controls, chronic pancreatitis, and PDAC by a proteomics approach using data-independent acquisition based mass spectrometry...

Pancreatic ductal adenocarcinoma (PDAC) is becoming the second leading cause of cancer-related death in the Western world. The mortality is very high, which emphasizes the need to identify biomarkers for early detection. As glutamine metabolism alteration is a feature of PDAC, its in vivo evaluation may provide a useful tool for biomarker identification. Our aim was to identify a handy method to evaluate blood glutamine consumption in mouse models of PDAC. We quantified the in vitro glutamine uptake by Mass Spectrometry (MS) in tumor cell supernatants and showed that it was higher in PDAC compared to non-PDAC tumor and pancreatic control human cells...

A 65-year-old male was referred to our hospital 2 years ago for a multilocular cyst accompanied with a protein plug in the pancreas tail. He was diagnosed as having branch duct-type intraductal papillary mucinous neoplasm and was followed-up. Two years later, endoscopic ultrasonography revealed a hypoechoic lesion, 10mm in diameter, near the cyst-like lesion. Finally, he was diagnosed with small pancreatic adenocarcinoma concomitant with intraductal papillary mucinous neoplasm and underwent radical distal pancreatectomy with splenectomy...
