Is the pancreas affected in patients with septic shock? A prospective study

Hyperamylasemia can be observed anecdotally during the course of severe sepsis or septic shock. This study aimed to investigate the possibility of pancreatic involvement in patients with septic shock using serum pancreatic enzyme determinations and imaging techniques in 21 consecutive patients with septic shock and 21 healthy subjects as controls. METHODS: The serum activity of pancreatic amylase and lipase was assayed initially in all subjects and 24 and 48 hours after the initial observation in the 21 patients with septic shock. All patients also underwent radiological examination to detect pancreatic abnormalities. RESULTS: The serum activity of pancreatic amylase was significantly higher in the 21 patients with septic shock than in the 21 control subjects during the study period, while the serum activity of lipase was similar to that of the control subjects. Amylase and lipase serum activity did not significantly changed throughout the study period in the 21 patients with septic shock. None of the patients with pancreatic hyperenzymemia had clinical signs or morphological alterations compatible with acute pancreatitis. CONCLUSION: The presence of pancreatic hyperenzymemia in septic shock patients is not a biochemical manifestation of acute pancreatic damage, and the management of these patients should be dependent on the clinical situation and not merely the biochemical result

Plasma concentrations of angiogenetic factors and angiogenetic inhibitors in patients with ductal pancreatic neoplasms. A pilot study

The aim of the study was to evaluate the circulating concentrations of vascular endothelial growth factor (VEGF), vascular endothelial growth factor receptor-2 (VEGFR-2), vascular endothelial growth factor-D (VEGF-D) and endostatin in patients with intraductal papillary mucinous neoplasm (IPMN), and in those with ductal adenocarcinomas. METHODS: Sixty patients (32 males, 28 females, mean age 69.3\ub111.3 years) were enrolled: 31 (51.7%) had IPMNs and 29 (48.3%) had histologically confirmed pancreatic adenocarcinomas. Thirty blood donors were also studied as controls. In all study subjects, the concentrations of VEGF, VEGF-D, VEGFR-2, and endostatin were determined using enzyme-linked immunosorbent assays. RESULTS: Serum concentrations of VEGF, VEGF-D, and VEGFR-2 were significantly higher in patients with pancreatic ductal adenocarcinoma and those with IPMNs compared with healthy subjects, while endostatin was significantly higher only in patients with pancreatic ductal adenocarcinoma compared with healthy subjects. Within the group of patients, VEGFR-2 was significantly higher in patients with ductal adenocarcinoma compared to those with IPMNs. The sensitivity and the specificity of VEGFR-2 in differentiating patients with ductal adenocarcinomas from those with IPMN at a cut-off range of 4003-4034 pg/mL was 86.2% and 54.8%, respectively. CONCLUSIONS: IPMNs have serum VEGFR-2 concentrations different from those in patients with ductal adenocarcinomas. However, serum VEGFR-2 cannot be routinely utilized to differentiate IPMNs from pancreatic ductal adenocarcinoma

Fecal calprotectin levels in patients with colonic polyposis

Context: The usefulness of stool calprotectin determination in diagnosis of inflammatory disease of the colon has been reported; information about its usefulness for patients with polyposis are scarce, however. Objective: To evaluate the significance of stool calprotectin concentrations for patients affected by colonic polyposis. Patients: Sixty-three consecutive patients (35 males, 28 females, mean age 60.3 years, range 39-78 years) were enrolled: 26 patients (41.3%) with polyps, 17 patients (27.0%) with asymptomatic diverticular disease, and 20 subjects (31.7%) with normal endoscopic appearance of the colon. Results: Stool calprotectin concentrations were 17.4 \ub1 24.5 \u3bcg g-1 for patients with colonic polyposis, significantly higher than concentrations for patients with diverticulosis (7.1 \ub1 5.7 \u3bcg g -1; P = 0.026) or for patients with normal appearance of the colon (calprotectin 6.0 \ub1 5.8 \u3bcg g-1; P = 0.003). For patients with a single polyp, stool calprotectin concentrations were similar to those for patients with multiple polyps. Calprotectin fecal concentrations for patients with sessile polyps and those with flat polyps were not significantly different. Calprotectin concentrations were not significantly related to the size of the polyps. Conclusion: Our data show that colonic polyposis may cause an increase in stool calprotectin values and that these colonic lesions should be suspected when elevated stool calprotectin concentrations are found

Pancreatic Ductal Adenocarcinoma Associated with Autoimmune Pancreatitis

Autoimmune pancreatitis (AIP), in contrast to other benign chronic pancreatic diseases, can be cured with immunosuppressant drugs, thus the differentiation of AIP from pancreatic cancer is of particular interest in clinical practice. There is the possibility that some patients with AIP may develop pancreatic cancer, and this possibility contributes to increasing our difficulties in differentiating AIP from pancreatic cancer. We herein report the case of a 70-year-old man in whom pancreatic adenocarcinoma and AIP were detected simultaneously. We must carefully monitor AIP patients for the simultaneous presence of pancreatic cancer, even when a diagnosis of AIP is confirmed

PREVALENCE AND DISTRIBUTION OF MUSCULAR METASTASES IN 55 DOGS WITH HEMANGIOSARCOMA. A WHOLE BODY COMPUTED TOMOGRAPHIC STUDY STUDY.

Hemangiosarcoma (HSA) is a neoplasm arising from vascular endothelium with a high metastatic rate. The purpose of the study was to determine the prevalence, localization and clinical signs of muscular metastases (MM). diagnosis of HSA, which underwent whole body CT within the time period from 2013 was reached by histology and/or cytology. The CT studies were reviewed by 2 of the authors (MP, MV). Signalment, clinical signs, localisation of the primary lesion and metastasis were retrieved. The chi-square and the Fisher exact tests were applied. The prevalence of MM in dogs with HSA is higher in comparison with previously published studies about MM in human and veterinary literature. The presence of MM signs could be confused with different health condition or metastatic spread to other organ systems. Whole body CT is recommended in dogs with HSA for staging of the oncologic patient

Observational prospective study comparing mucoactive and antibiotic treament in the management of acute cough from upper respiratory tract infections

Since the efficacy of antibiotics in the management of cough from upper respiratory tract infections (URTI) is unclear, we conducted an observational study to evaluate the efficacy of antibiotic compared to symptomatic treatment in adults with productive cough from URTI in a real life setting
