Dengue fever is an acute febrile viral disease, which frequently presents with high fever, headache, bone pain and skin rash. Acute pancreatitis and seizure are rare manifestations of dengue virus infection. A 66-year-old woman with diabetes mellitus presented with epigastralgia, nausea, vomiting, diarrhea and fever. Acute pancreatitis, abnormal liver function and thrombocytopenia were diagnosed at a local hospital. After persistent fever, thrombocytopenia and seizure developed she was transferred to our medical center. Dengue virus infection was confirmed by serology study and dengue hemorrhagic fever grade II was diagnosed. No further neurological symptoms occurred and pancreatitis improved gradually after supportive care. She recovered and had no sequelae at 1 year follow-up. Acute pancreatitis and seizure may be manifestations of dengue virus infection, especially in patients with delayed diagnosis, prolonged fever and thrombocytopenia.

Forty-three hemophiliacs with AIDS or ARC received a daily dose of 334 or 500 mg didanosine (2',3'-dideoxyinosine or ddI) orally in 2 divided doses in phase I/II, open-label clinical trial conducted in Japan. Twenty-eight patients completed 6 months of therapy. There was an increase in circulating CD4(+) cells in 19 valuable patients from 91 +/- 25 (mean +/- SE) at entry to 131 +/- 38 at 24 weeks of therapy P = 0.01; Wilcoxon signed rank). Fourteen of 37 patients met the criteria for CD4 rise >/= 50/mm3 rise or >/= 50% increase from entry values) for more than 4 consecutive weeks. Twenty patients were p24 positive at entry. Nine out of the 10 evaluable patients (90%) showed a decline in p24 antigen at weeks 20-24 (P = 0.02). Thirty-five patients had symptoms related to HIV-1 infection at entry. Twenty-seven patients reported improvements in constitutional symptoms during therapy. Nine patients presented with possible drug-related adverse effects, and didanosine was discontinued in 6 patients (one each with edema; abdominal pain with anorexia; hematuria with edema and rash; sense of abdominal distension with anorexia; diarrhea and abdominal pain; and irritability). One patient had a transient increase in serum amylase level to twice the upper limit of normal, but he continued to receive the drug. These data suggest that didanosine was generally well tolerated in hemophiliacs with AIDS or ARC, and its administration correlated with improvement in constitutional symptoms and laboratory findings. The adverse effects of didanosine seen in this population were moderate to mild, and no complications related to hemorrhagic diathesis were observed, although the relative risk of acute pancreatitis in this population (while not seen in the present study to date) requires more study.

We reviewed the medical records of 62 patients with systemic small and medium-sized vessel vasculitides and gastrointestinal tract involvement followed at our institution between 1981 and 2002. This group included 46 men and 16 women (male:female ratio, 2.9), with a mean age of 48 +/- 18 years. Vasculitides were distributed as follows: 38 polyarteritis nodosa (21 related to hepatitis B virus), 11 Churg-Strauss syndrome, 6 Wegener granulomatosis, 4 microscopic polyangiitis, and 3 rheumatoid arthritis-associated vasculitis. Gastrointestinal manifestations were present at or occurred within 3 months of diagnosis in 50 (81%) patients and were mainly abdominal pain in 61 (97%), nausea or vomiting in 21 (34%), diarrhea in 17 (27%), hematochezia or melena in 10 (16%), and hematemesis in 4 (6%). Gastroduodenal ulcerations were detected endoscopically in 17 (27 %) patients, esophageal in 7 (11%), and colorectal in 6 (10%), but histologic signs of vasculitis were found in only 3 colon biopsies. Twenty-one (34%) patients had a surgical abdomen; 11 (18%) developed peritonitis, 9 (15%) had bowel perforations, 10 (16%) bowel ischemia/infarction, 4 (6%) intestinal occlusion, 6 (10%) acute appendicitis, 5 (8%) cholecystitis, and 3 (5%) acute pancreatitis. (Some patients had more than 1 condition.) Sixteen (26%) patients died.The respective 10-month and 5-year survival rates were 71% (95% confidence interval [CI], 52-90) and 56% (95% CI, 35-77) for the 21 surgical patients; and 94% (95% CI, 87-101) and 82% (95% CI, 70-94) for the 41 patients without surgical abdomen (p = 0.08). Peritonitis (hazard ratio [HR] = 4.3, p < 0.01), bowel perforations (HR = 5.7, p < 0.01), gastrointestinal ischemia or infarctions (HR = 4.1, p < 0.01), and intestinal occlusion (HR = 5.5, p < 0.01) were the only gastrointestinal manifestations significantly associated with increased mortality in multivariate analysis. For this subgroup of 15 patients, 6-month and 5-year survival rates were 60% (95% CI, 35-85) and 46% (95% CI, 19-73), respectively (p = 0.003). None of the other gastrointestinal or extraintestinal vasculitis-related symptoms, or angiographic abnormalities (seen in 67% of the 39 patients who underwent angiography), was predictive of surgical complications or poor outcome. However, prognosis has dramatically improved during the past 30 years, probably owing to better management of these more severely ill patients, with prompt surgical intervention when indicated, and the combined use of steroids and immunosuppressants.

Complications of acute pancreatitis usually occur in pancreas and its contiguous organs. The prevalence of colonic invasion is rare, however, the consequence is fatal, with mortality above 50%. The initial symptoms and onset times are variable and major affected sites are transverse colon and splenic flexure. The spread of inflammatory exudates into the colon is the main mechanism of colonic invasion. If the colonic stenosis develops, it is necessary to manage it surgically. We report a case who arrived at the hospital with watery diarrhea and abdominal distension in the recovery period of acute alcoholic pancreatitis and was diagnosed as a colonic obstruction in the splenic flexure. The patient underwent loop ileostomy instead of the resection of the lesion because of severe adhesion around the splenic flexure. The patient died due to sepsis 5 days after the operation.

We are reporting a forty-seven year old female who had three attacks of acute pancreatitis after having; eaten bananas. She was treated with a light diet and intravenous fluids during each of her admissions. The treatment concluded with the disappearance of clinical symptoms such as epigastralgia, nausea, vomiting and diarrhea within a few days. In addition, elevated serum and urine amylase levels returned to normal values in parallel with the clinical symptoms. The data during her three attacks of acute pancreatitis were as follows: serum total IgE level = 644 IU/mL, specific IgE to bananas = 2.18 UA/ml. No remarkable abnormalities were present in sonography, computed tomography, magnetic resonance imaging of the abdomen, and magnetic resonance cholangiopancreatography. Endoscopic examination of the upper digestive tract showed the ampulla of Vater swollen and edematous, thus a biopsy was performed. Toluidine blue staining and immunohistochemical staining against human mast cell tryptase with the biopsy specimens showed mast cells accumulating in mucosa and submucosa. By avoiding consumption of bananas, she has not suffered from any additional attacks of pancreatitis since the third attack in the last thirty-four months up to this day of December 10, 2004.

Primary pancreatic lymphomas are extremely rare. Clinically, primary pancreatic lymphomas usually present with symptoms of carcinoma of the pancreatic head. Patients with primary pancreatic lymphomas are between 35 and 75 years of age and with a strong male predominance. Common clinical manifestations include abdominal pain, jaundice, acute pancreatitis, small bowel obstruction, and diarrhea. An accurate cytopathologic diagnosis by fine-needle aspiration (FNA) is imperative because the primary treatment is non-surgical. Cytomorphologic features include hypercellularity with discohesive cells with round nuclei, often prominent nucleoli, mitoses, and karyorrhexis. Flow cytometry analysis demonstrates a monoclonal pattern of immunoglobulin light chain expression. FNA coupled with flow cytometry analysis appears to be highly accurate in the diagnosis of primary pancreatic lymphomas. Fluorescence in-situ hybridisation technique has been established its role in the diagnosis of lymphoid malignancies, including primary pancreatic lymphomas. LDH and beta-2 microglobulin are important diagnostic and prognostic tumor markers. The differential diagnoses of primary pancreatic lymphomas include secondary lymphoma, pancreatic endocrine neoplasm, and florid chronic pancreatitis. The role of surgery is limited to the rare occasions when initial FNA and flow cytometry analysis are non-diagnostic. Treatment usually consists of a combination of chemotherapy and radiation therapy, or stem cell transplantation. Primary pancreatic lymphomas has a much better prognosis than adenocarcinoma of the pancreas.

This article revises the concepts of prebiotics, probiotics and symbiotics, and their use in different situations of daily clinical practice. With a high level of evidence, it is concluded that the use of certain strains of probiotics significantly reduces the risk for antibiotic-induced diarrhea. Although further studies are needed, the use of probiotics, prebiotics, and symbiotics in people suffering from inflammatory bowel disease (particularly ulcerative colitis, and pouchitis) might improve the rates of remission induction/maintenance. The administration of probiotics and symbiotics to patients with liver transplant, severe acute pancreatitis, and intensive and surgical care patients, emerges as a promising therapeutic option that seems to reduce the number of infections; however, it is currently no possible to establish evidence-based recommendations, with a need for a higher number of better designed works. About safety of probiotics and symbiotics, the benefits/risks ratio clearly favors the former since the risk for infection is low, even in immunosuppressed patients. There are, however, selected groups of patients in which caution is advised.

Severe sepsis with associated multisystem organ dysfunction is a leading cause of death in patients hospitalized in intensive care units. The gastrointestinal system plays a key role in the pathogenesis of multisystem organ dysfunction owing to a breakdown of intestinal barrier function and increased translocation of bacteria and bacterial components into the systemic circulation. During critical illness, alterations occur in gut microflora owing to several factors, including changes in circulating stress hormones, gut ischemia, immunosuppression, the use of antibiotics, and lack of nutrients. The importance of endogenous strains of probiotic bacteria such as Bifidobacterium and Lactobacillus in maintaining intestinal barrier function and also in modulating mucosal and systemic immune responses is becoming evident from numerous studies. Bacteria in synbiotic (prebiotic and probiotic combinations) and probiotic (mutistrain combinations) preparations are being used experimentally in the treatment of acute pancreatitis, liver transplantation, and in trauma patients. Recent studies have shown treatment of patients with multiple trauma or acute pancreatitis with synbiotic preparations resulted in reduced rates of infection, sepsis, and mortality in patients. Enterally fed patients in the intensive care unit treated with a probiotic compound demonstrated enhanced immune function and decreased incidence of diarrhea. Results from these clinical trials are encouraging, and warrant further investigation to clarify which probiotic bacterial strains are of most benefit to this population.

The management of unresectable metastatic melanoma is a major clinical challenge because of the lack of reliably effective systemic therapies. Blocking cytotoxic T lymphocyte-associated antigen-4 (CTLA-4) has recently been proposed as a strategy to enhance cell-mediated immune responses to cancer, and clinical trials have demonstrated that anti-CTLA-4 therapy can produce durable outcomes with different response patterns than cytotoxic chemotherapy. We enrolled eight out of 155 patients with advanced melanoma in a multicentre phase II trial that evaluated the activity and tolerability of ipilimumab, a fully human, anti-CTLA-4 monoclonal antibody ( www.clinicaltrials.gov ; NCT00289627; CA184-008). Here we report our experience with three of these patients, who experienced progressive disease after a variety of previous therapies, including prior immunotherapies, and who achieved good outcomes with ipilimumab. One patient had a partial response ongoing at 17+ months on ipilimumab despite failure with four prior therapies, and the other two patients showed durable stable disease, both still ongoing at 17+ and 20+ months, respectively. The patient achieving a partial response experienced no side effects while receiving ipilimumab. The other two patients developed immune-related adverse events (irAEs) including rash (one case; grade 2) and diarrhoea (both cases; grades 1 and 2, respectively); the histopathology of colon biopsy samples from both was suggestive of colitis, with an abundant CD8+ T-cell infiltrate. Nausea, vomiting and acute pancreatitis were also observed in one patient. In addition, immunohistochemical findings of a dense CD8+, TIA1+ and granzyme B+ lymphoid infiltrate within a biopsied lesion provide indirect evidence of functional T-cell activation induced by treatment. These case reports highlight the potential for anti-CTLA-4-based therapy in previously treated patients with advanced melanoma. Moreover, because the patterns of response to ipilimumab differ from chemotherapy, we need to understand how and when patients may respond to treatment so that appropriate clinical decisions can be made.

It has been proposed that probiotics can favorably influence the course of critically ill patients. To address this question, a limited systematic review was undertaken (MEDLINE search for articles published in English) to identify randomized, controlled trials that compared a group of critically ill patients taking probiotics with a group that did not. Ten such trials, mostly with high risks of methodologic bias, were identified. When the data were combined, the probiotics did not appear to influence mortality or duration of hospitalization. However, the recipients of the probiotics had fewer infectious episodes (absolute risk difference-21%). This effect was seen particularly in trials employing one combination of probiotic agents (Pediococcus pentosaceus, Leuconostoc mesenteroides, Lactobacillus paracasei, Lactobacillus plantarum). Unfortunately, this effect may be overly optimistic, as methodologic shortcomings could have introduced biases into the trials. Three trials of patients with severe acute pancreatitis were not included in this primary analysis because not all of the patients were in the intensive care unit. The largest of these, and the one with the lowest risk of bias, demonstrated that probiotics increased mortality, in part because of the precipitation of ischemic bowel disease (in patients who were also receiving postpyloric enteral nutrition infusions). Probiotics also appeared to reduce the incidence of antibiotic-associated diarrhea in hospitalized patients, although these trials did not specifically focus only on those who were critically ill. In summary, it is not clear that probiotics are beneficial (and they may even be harmful) in the critically ill patient group.
