The enteric nervous system is involved in most of the physiological and pathophysiological processes in the gastrointestinal tract. This Minireview is part two of three and describes the role of the enteric nervous system in gastrointestinal functions (motility, exocrine and endocrine secretions, blood flow, and immune processes) in health and some disease states. In this context, the functional importance of the enteric nervous system for food intake, the gall bladder, and pancreas will be addressed. In specific, dysmotility, diarrhoea, constipation, non-occlusive intestinal ischaemia (intestinal angina), inflammation, cholelithiasis, cholecystitis, postcholecystectomy syndrome, and pancreatitis can be treated with neuroactive pharmacological agents. For example, serotonin receptor type four agonists can be used for the treatment of constipation, while nitric oxide synthesis inhibitors can be employed for the treatment of intestinal angina.

Acute abdominal pain in children occurs often and requires rapid clarification. Hints as to the condition are often given by the first impression and the case history of the patient. When the clinical examination and laboratory results do not lead to a clear finding, imaging methods such as a sonography can clarify the case. The most common cause for abdominal pain in infants is acute enteritis, mostly brought about by rotaviruses. Additional diagnoses are abdominal hernia, malrotation, hypertrophic pyloric stenosis, invagination or gastroesophageal reflux. In school-age children, the classic finding is "appendicitis". This should be differentiated from constipation, gastritis, pancreatitis, sigmoid volvulus, bowel and intestinal obstruction or, perhaps, gallstone trouble.

Colonic involvement in patients with severe acute pancreatitis or chronic pancreatitis is common and complications such as paralytic ileus, segmental necrosis and pancreatic-colonic fistulae have been described. However, mechanical occlusion of the colon due to pancreatitis is infrequent. We present the case of a 45-year-old man with occlusion of the colon secondary to asymptomatic pancreatitis mimicking a locally advanced stenosing neoplasm of the splenic angle. Ten years prior to the present episode the patient had presented acute alcoholic pancreatitis complicated by a pseudocyst requiring surgery. The current reason for admission was abdominal colic pain and constipation with onset 5 days previously. Contrast enema was administered showing colonic occlusion caused by stenosis at the splenic flexure, suggesting the presence of a neoplasm. Urgent laparotomy showed the presence of a tumor originating in the colon that infiltrated the splenic hilum. Subtotal colectomy and en-bloc splenectomy were performed. Histopathological analysis showed pericolonic inflammation and fibrosis secondary to pancreatitis; the colonic mucosa showed no tumoral infiltration. To date, fewer than 30 cases of this infrequent complication have been published.

With the ever-growing armamentarium of pharmacological agents, the gastrointestinal drug-induced side effects of dyspepsia, nausea, vomiting, diarrhoea and constipation are increasingly seen. They are often self-limiting and without serious sequelae, but of greater concern is drug-induced mucosal ulceration that can manifest as gastrointestinal haemorrhage, stricture and perforation. These complications are mainly attributable to NSAIDs and aspirin, which can injure the mucosa anywhere along the gastrointestinal tract. These iatrogenic serious side effects can be reduced with co-prescription of a proton pump inhibitor, substitution of a COX-2 inhibitor and eradication of Helicobacter pylori when the bacterium is present. Other recognised gastrointestinal complications include small intestinal diaphragm, microscopic colitis, a range of hepatotoxic effects and pancreatitis. The introduction of new classes of drugs has resulted in new adverse effects that require consideration in patients presenting with gastroenterological symptoms. These include pill oesophagitis from bisphosphonates and ischaemic colitis relating to serotonin antagonists. Here, the authors review the literature on drug-induced complications of the gastrointestinal tract and present the pertinent management issues relevant to clinical practice.

Arsenic trioxide (ATO) induces remission in 85% of adults with refractory acute promyelocytic leukemia (APL). We conducted a phase 1 trial of ATO in children (median age 13 y, range, 2-19) with refractory leukemia. ATO was administered intravenously over 2 hours, 5 d/wk for 20 doses/cycle. Patients with APL (n=13) received 0.15 mg/kg per day, and patients with other types of leukemia received 0.15 mg/kg per day (n=2) or 0.2 mg/kg per day (n=4). Nineteen of the 24 enrolled patients were fully evaluable for toxicity. At 0.15 mg/kg per day, 2 of 15 patients experienced dose-limiting corrected QT interval (QTc) prolongation, pneumonitis, or neuropathic pain. At 0.2 mg/kg per day, 2 of 4 patients had dose-limiting QTc prolongation or pancreatitis. Non-dose-limiting toxicities included elevated serum transaminases, nausea, vomiting, abdominal pain, constipation, electrolyte imbalance, hyperglycemia, dermatitis, and headache. At 0.15 mg/kg per day, the median (range) plasma arsenic maximum concentration (Cmax) was 0.28 microM (0.11-0.37 microM) and at 0.2 mg/kg per day, Cmax was 0.40 and 0.46 microM; area under the concentration times time curve (AUC0-24) was 2.50 microM-hr (1.28-3.85 microM-hr) and 4.37 microM-hr and 4.69 microM-hr, respectively. Morphologic complete response (CR) was achieved in 85% of patients with APL; no responses were observed in non-APL patients. ATO is well-tolerated in children at the recommended dose of 0.15 mg/kg per day. The response rate in children with relapsed APL is similar to the response rate in adults. This trial was registered as #NCT00020111 at www.ClinicalTrials.gov.

Gastrin and cholecystokinin (CCK) are two of the oldest hormones and within the past 15 years there has been an exponential increase in knowledge of their pharmacology, cell biology, receptors (CCK1R and CCK2R), and roles in physiology and pathological conditions. Despite these advances there is no approved disease indication for CCK receptor antagonists and only a minor use of agonists. In this review, the important factors determining this slow therapeutic development are reviewed. To assess this it is necessary to briefly review what is known about the roles of CCK receptors (CCK1R and CCK2R) in normal human physiology, their role in pathologic conditions, the selectivity of available potent CCKR agonists/antagonists as well as to review their use in human conditions to date and the results. Despite extensive studies in animals and in humans, recent studies suggest that monotherapy with CCK1R agonists will not be effective in obesity, nor CCK2R antagonists in panic disorders or CCK2R antagonists to inhibit growth of pancreatic cancer. Areas that require more study include the use of CCK2R agonists for imaging tumors and radiotherapy, CCK2R antagonists in hypergastrinemic states especially with long-term PPI use and for potentiation of analgesia as well as use of CCK1R antagonists for a number of gastrointestinal disorders [motility disorders (irritable bowel syndrome, dyspepsia, and constipation) and pancreatitis (acute and chronic)].

Gastrointestinal complications are common in patients undergoing various forms of cancer treatment, including chemotherapy, radiation therapy, and molecular-targeted therapies. Many of these complications are life-threatening and require prompt diagnosis and treatment. Complications of oncologic therapy can occur in the esophagus (esophagitis, strictures, bacterial, viral and fungal infections), upper gastrointestinal tract (mucositis, bleeding, nausea and vomiting), colon (diarrhea, graft-versus-host disease, colitis and constipation), liver (drug hepatotoxicity and graft-versus-host disease), and pancreas (pancreatitis). Treatment of the different gastrointestinal complications should be tailored to the individual patient and based on the underlying pathophysiology of the complication.

This review discusses gastrointestinal manifestations of parathyroid diseases. Parathyroid hormone is the primary regulator of calcium physiology. Hypoparathyroidism can be idiopathic, hereditary, or secondary to surgery in the neck. Hyperparathyroidism is usually from adenomas or hyperplasia. Hypoparathyroidism is associated with steatorrhea that may improve with medium-chain triglycerides, correction of the hypoparathyroidism, or administration of vitamin D. Hyperparathyroidism results in constipation because of reduction in neuromuscular excitability by high calcium levels. According to old literature, the incidence of peptic ulcer disease (PUD) in patients with hyperparathyroidism is 9% compared with autopsy rates of 4% to 5%. Any association is difficult to prove today, as hyperparathyroidism is usually mild due to early detection of cases through routine automated measurements of calcium. In addition, PUD is less prevalent now than before the advent of proton pump inhibitors. The presence of ulcers or ulcer symptoms may correct in some patients after parathyroidectomy, suggesting an association. The incidence of pancreatitis in patients with primary hyperparathyroidism ranges from 1.5% to 12% and may be because of the hypercalcemia. Complicating the issue is secondary hyperparathyroidism in response to hypocalcemia from pancreatitis. Pancreatitis may improve in some individuals after parathyroidectomy. Pancreatitis may follow parathyroid surgery because of an acute rise in calcium levels with manipulation of the parathyroid glands or to a blunted response of calcitonin-producing cells from fatigue. Parathyroid diseases have a few distinct effects on the gut: steatorrhea in hypoparathyroidism, and constipation, PUD, and pancreatitis in hyperparathyroidism.

The objective of this article is to describe adverse drug events related to the liver and gastrointestinal tract in critically ill patients. PubMed and other resources were used to identify information related to drug-induced acute liver failure, gastrointestinal hypomotility, constipation, diarrhea, gastrointestinal bleeding, and pancreatitis in critically ill patients. This information was reviewed, and data regarding pathophysiology, common drug causes, and guidelines for prevention and management were collected and summarized. In cases in which data in critically ill patients were unavailable, data were extrapolated from other patient populations. Drug-induced acute liver failure can be caused by many drugs routinely used in the intensive care unit and may be associated with significant morbidity and mortality. Drug-related hypomotility and constipation and drug-related diarrhea are reported with many drugs, and these are common adverse drug events in critically ill patients that can substantially complicate the care of these patients. Drug-induced gastrointestinal bleeding and drug-induced pancreatitis occur less frequently, can range in disease severity, and can be associated with morbidity and mortality. Many drugs used in critically ill patients are associated with adverse drug events related to the liver and gastrointestinal tract. Critical care clinicians should be aware of common drug causes of drug-induced acute liver failure, gastrointestinal hypomotility, constipation, diarrhea, gastrointestinal bleeding, and pancreatitis, and should be familiar with the prevention and management of these diverse conditions.

Background. The present study sought and compared the utility and safety of endoscopic retrograde cholangiopancreatography (ERCP) in the elderly and younger people in a great sample of Iranian population. Methods. Our study involved 780 patients undergoing diagnostic and therapeutic ERCP at the Taleghani hospital in Tehran between 2010 and 2011; among them, 558 patients were less than 70 years old and others were 70 years old or older. The patients were prospectively identified and data including clinical and biochemical features, ERCP procedures, ERCP diagnosis, and ERCP complications were gathered on them prospectively. Results. Clinical manifestations were comparable in young and older groups except for hepatosplenomegaly and constipation that were more prevalent in the elderly. Laboratory findings were similar in both groups other than mean levels of alkaline phosphatase, hemoglobin and albumin levels, which were higher in the elderly group. Selective biliary cannulation was technically more successful in the younger than in others (89.0% versus 81.8%). Common bile duct stone was the most frequent diagnosis in both young and older groups (36.6% and 45.9%, resp.), whereas ERCP was reported to be normal in 13.4% of the younger and 5.0% of the elderly patients. Post-ERCP complications were observed in 4.8% of patients aged less than 70 years in comparison with 2.3% of patients aged over 70 years. The most frequent complication was pancreatitis that was significantly more developed in young than older patients (3.6% versus 1.5%; OR: 8.216, P = 0.015). Conclusion. Diagnostic ERCP is safe and well tolerated in the elderly and even associated with significantly less risk than the younger.
