1/121. pancreatic polypeptide hyperplasia causing watery diarrhea syndrome: a case report.Neuroendocrine tumours of the pancreas can secrete numerous peptides, leading to various recognizable clinical syndromes. The secretion of pancreatic polypeptide has been used as a marker for neuroendocrine tumours but is considered to be a biologically inert peptide. A 37-year-old woman had watery diarrhea syndrome from pancreatic polypeptide hyperplasia. Only 2 other reported cases in the literature have described pancreatic polypeptide hyperplasia; however, this is the first reported case in which the patient was successfully treated by surgical resection, with a 2-year follow-up. This report and review of the literature illustrate that pancreatic polypeptide hypersecretion may present as a clinical endocrinopathy.- - - - - - - - - - ranking = 1keywords = diarrhea syndrome, watery diarrhea, diarrhea (Clic here for more details about this article) |
2/121. Treatment of metastatic vipoma by liver transplantation.We report the first case of metastatic vipoma treated by orthotopic liver transplantation. A woman with explosive secretory diarrhea causing hypokalemic acidosis was diagnosed as having a vasoactive intestinal peptide secreting tumor with widespread hepatic metastases. The symptoms were initially controlled for 9 months with increasing doses of long-acting somatostatin analogue (Sandostatin, Sandoz Ltd, UK). Alpha interferon was not tolerated, causing an acute paranoid psychosis. Eventually orthotopic liver transplantation was performed with the removal of the primary tumor from the distal pancreas. Postoperatively, complications were associated with the distal pancreatectomy. The patient has no evidence of tumor recurrence on imaging or serum VIP level 12 months posttransplantation.- - - - - - - - - - ranking = 0.00087860803279387keywords = diarrhea (Clic here for more details about this article) |
3/121. Long-term survival after diagnosis of hepatic metastatic vipoma: report of two cases with disparate courses and review of therapeutic options.This report describes two patients with pancreatic cholera caused by vasoactive intestinal polypeptide (VIP)-producing tumors, which originated in the pancreas and showed metastases in both hepatic lobes at time of diagnosis. However, the two tumors displayed remarkably disparate clinical courses. Due to the protracted but progressive course over more than 10 years, a multifaceted therapeutic approach was performed to control symptoms and to improve quality of life. The long-acting somatostatin analog octreotide was the most effective treatment for relieving symptoms and correcting fluid and electrolytes disturbances. The effects of complementary treatments, including systemic chemotherapy and hyperselective chemoembolization, as well as concurrent application of octreotide and prednisolone or interferon with respect to clinical symptoms, VIP levels, and tumor growth are reviewed. Our experience, although small, emphasizes the need for an expert, well-planned, adaptive, and multidisciplinary approach in the care of these complex patients.- - - - - - - - - - ranking = 0.59394615335968keywords = pancreatic cholera, cholera (Clic here for more details about this article) |
4/121. Microscopic colitis syndrome: lymphocytic colitis and collagenous colitis.Microscopic colitis is a syndrome consisting of chronic watery diarrhea, a normal or near-normal gross appearance of the colonic lining, and a specific histological picture described as either lymphocytic colitis or collagenous colitis. Since its initial descriptions a quarter of a century ago, microscopic colitis has become a frequent diagnosis in patients with chronic diarrhea. Understanding of the cause and pathogenesis of microscopic colitis remain incomplete, but potentially important clues have been discovered that shed light on predisposing factors. In particular, specific HLA-DQ genotypes may be permissive for the development of microscopic colitis, and suggest a linkage to the pathogenesis of celiac sprue. Although the differential diagnosis of chronic watery diarrhea is broad, the diagnosis of microscopic colitis is straightforward, involving endoscopic inspection of the colonic mucosa and proper pathologic interpretation of biopsy specimens. As the limitations of drugs ordinarily used for other forms of inflammatory bowel disease are being recognized, new approaches, such as the use of bismuth subsalicylate, are being evaluated. The prognosis of patients with microscopic colitis syndrome remains good, and symptomatic improvement can be expected in most patients.- - - - - - - - - - ranking = 0.16445458729412keywords = watery diarrhea, diarrhea (Clic here for more details about this article) |
5/121. Carcinoid syndrome caused by an atypical carcinoid of the uterine cervix.neuroendocrine tumors of the cervix are rare and are often under- or misdiagnosed. Because these tumors are very aggressive, early diagnosis and subsequent treatment are warranted. We describe a 46-yr-old woman with carcinoid syndrome caused by an atypical carcinoid of the uterine cervix. At age 44, she had dysplasia on Pap smear and underwent total abdominal hysterectomy with the diagnosis of adenocarcinoma. Fourteen months postoperatively, she developed the carcinoid syndrome and was found to have numerous liver metastases. Histological and immunohistochemical investigations of biopsy specimens from the patient's liver lesions and original cervical lesion ("adenocarcinoma") suggested that this woman had a primary atypical carcinoid of the uterine cervix with metastases to the liver. Treatment with octreotide and alkylating agents decreased the episodes of flushing and diarrhea within 8 weeks. If an adenocarcinoma of the uterine cervix is diagnosed, atypical carcinoid should be in the differential diagnosis. Symptoms of the carcinoid syndrome should be pursued and, if present, a urinary 5-hydroxyindolacetic acid level should be obtained. Timely diagnosis of a neuroendocrine tumor of the cervix may improve survival.- - - - - - - - - - ranking = 0.00087860803279387keywords = diarrhea (Clic here for more details about this article) |
6/121. Pancreatic tumors in children: report of three cases.From 1981 to 1996, we experienced 3 cases of pancreatic tumors in children--two pancreatoblastomas (PB) and one solid and cystic tumor (SCT). The ages were 1 month, 4 years, and 13 years of age respectively. The two cases of pancreatoblastoma initially presented as chronic diarrhea with failure to thrive, the other case presented with abdominal mass. All of them were studied by laboratory examination, ultrasonography, computed tomography and pathology. Increasing alpha- fetoprotein (AFP) levels were found in the 2 pancreatoblastoma cases, however, the level in the SCT case was normal. Abdominal sonography showed pancreatic masses with or without calcification, and the echogenicity may be solid and/or cystic. All patients underwent total excision of the tumors. We have reviewed the literature and find no pancreatoblastoma with chronic diarrhea was reported in young children, especially in neonate. Therefore, we suggest that young children presenting with an abdominal mass and/or weight loss should undergo imaging studies for the possibility of pancreatic tumors.- - - - - - - - - - ranking = 0.0017572160655877keywords = diarrhea (Clic here for more details about this article) |
7/121. Nonfunctioning pancreatic tumor manifestated as abdominal mass in a child.This report concerns a 9-year-old girl with a nonfunctioning pancreatic tumor presented as an abdominal mass. An encapsulated tumor, measuring approximately 8 x 7 cm, was found during operation, and debulking surgery was done. Histopathologic studies proved that it was a pancreatic tumor, compatible with non-functioning islet cell tumors. She displayed neither clinical picture of jaundice, nor excessive hormonal manifestations such as diarrhea or flushing. No evidence would suggest its association with multiple endocrine neoplasia type I. To our knowledge, it has never been reported in children in taiwan.- - - - - - - - - - ranking = 0.00087860803279387keywords = diarrhea (Clic here for more details about this article) |

9/121. Different response to the long-acting somatostatin analogues lanreotide and octreotide in a patient with a malignant carcinoid.INTRODUCTION: somatostatin (SST) analogues are cornerstones in the symptomatic management of patients suffering from carcinoid tumors, and antiproliferative activity has also been reported for these agents. The most commonly applied SST analogues are octreotide (OCT) and lanreotide (LAN), which are both available in a slow release formulation. To the current knowledge, both OCT and LAN are thought to be equally effective for the management of various disorders. We report the case of a patient with a disseminated carcinoid, who progressed during dose-intensified treatment with slow-release LAN in combination with interferon-alpha, but developed a pronounced response after treatment was switched to the application of a depot formulation of OCT. CASE REPORT: A 46-year-old woman was admitted to our department for the evaluation of persistent flushing, diarrhea and dyspnea. After a diagnosis of metastatic carcinoid had been established, treatment with LAN (30 mg i.m. every 10 days) along with interferon-alpha 3 x 5 MU/week was initiated. In spite of successful blocking of tumoral SST receptors as judged by SST receptor scintigraphy and subjective improvement of symptoms, the patient had progressive disease. As she refused chemotherapy, treatment was switched to a depot formulation of OCT (20 mg i.m. every 4 weeks), resulting both in a disappearance of symptoms as well as tumor regression as seen on CT scanning. CONCLUSION: To our knowledge, this is the first case demonstrating both a symptomatic as well as objective response to OCT following progression during therapy with LAN in a patient with a carcinoid tumor. Our results suggest that refractoriness to treatment including a long-acting SST analogue does not automatically imply resistance to a related agent and should alert clinicians to the potential of non-cross-resistance between SST analogues in neuroendocrine malignancies.- - - - - - - - - - ranking = 0.00087860803279387keywords = diarrhea (Clic here for more details about this article) |
10/121. Surgical treatment of pancreatic vasoactive intestinal polypeptide-secreting tumor: a case report.A 68-year-old woman presented with secretory watery diarrhea causing hypokalimia, hypoalbuminemia and dehydration for 5 years. Subsequent investigations including abdominal ultrasonography and computed tomography scanning revealed a mass measuring 7 x 6 cm in the pancreatic tail. The diagnosis of pancreatic VIPomas was suspected on the basis of clinical symptoms. The patient underwent distal pancreatectomy and splenectomy after resuscitation of electrolyte imbalance, dehydration and malnutrition. The pathological examination with histoimmunochemical stain confirmed the diagnosis. Postoperative course is uneventful and the patient does not have symptoms any longer during the follow-up period.- - - - - - - - - - ranking = 0.081787989630661keywords = watery diarrhea, diarrhea (Clic here for more details about this article) |
