We sought to prospectively characterize and compare the symptoms of children > or = 5 years of age with recurrent abdominal pain to previously established criteria for irritable bowel syndrome (IBS) in adults. For all eligible subjects, a detailed questionnaire concerning characteristics of abdominal pain and defecatory pattern was completed at presentation. In addition, a battery of screening tests was performed and additional evaluation was done at the discretion of their physician. In all, 227 subjects fulfilled the entrance criteria, but 56 were subsequently excluded because of diagnoses of inflammatory bowel disease (nine cases), lactose malabsorption (46 cases), or celiac disease (one case). Of the remaining 171 patients, 117 had IBS symptoms. In the IBS subjects, lower abdominal discomfort (p < 0.001), cramping pain (p < 0.0009), and increased flatus (p < 0.0003) were more common, whereas dyspeptic symptoms such as epigastric discomfort (p < 0.003), pain radiating to the chest (p < 0.009), and regurgitation (p < 0.02) were more common in the non-IBS subjects. Our study not only confirms the clinical heterogeneity of children with recurrent abdominal pain but also concomitantly demonstrates that most children with this disorder have symptoms that fulfill the standardized criteria for IBS in adults. The identification of subgroups of children with recurrent abdominal pain can provide a framework for the diagnosis of functional bowel disease as well as establish the need for invasive and expensive tests.

Helicobacter pylori is present in up to 87% of patients with nonulcer dyspepsia. This study assessed the effect of eradicating Helicobacter pylori infection on the symptoms of nonulcer dyspepsia at four weeks and one year after treatment. Dyspepsia was assessed on the frequency and severity of six symptoms [epigastric pain (night and day), nausea and vomiting, upper abdominal discomfort, and regurgitation] where each symptom was scored from 0 to 4. Helicobacter pylori status was assessed before treatment and four weeks after treatment with histology and microbiology, and at one year with a carbon-13 urea breath test. Eighty-three patients (23 males, 60 females; mean age 56.3 years; mean symptom duration 3.6 months) with nonulcer dyspepsia and Helicobacter pylori infection entered the study. Seventy-five were available at one year follow-up. Four weeks after treatment, the mean symptom score improved in those with eradication (6.95-2.3, P = 0.01, N = 41) or persistent infection (6.69-3.0, P = 0.015, N = 42). At one year, those with persistent Helicobacter pylori infection (N = 38, score 5.24) had a higher score than those remaining clear of infection (N = 24, score 1.4, P < 0.0001) and those with reinfection (N = 13, score 2.2, P < 0.0001). In addition, persistent Helicobacter pylori infection was associated with more additional treatments than those with eradication (34/38 versus 4/37, P < 0.001). These results suggest that Helicobacter pylori plays an important role in the symptoms of nonulcer dyspepsia.

A 46-year-old Chinese woman was admitted to our hospital because of presence of space-occupying lesions in the liver for 2 months in April, 2015. She had a family history of multiple endocrine neoplasia type 1 (MEN1) and physical examination is unremarkable. Previously, she has performed surgery for primary pituitary tumor in 2002 and radiosurgery for its recurrence. Around December 2014, she suffered from abdominal discomfort associated with regurgitation and gastroscopy revealed "gastroduodenal ulcers", along with elevated gastrin. Next, both magnetic resonance and computed tomography imaging showed multiple intrahepatic lesions, the PET-CT unveiled uptake pattern of 18F-FDG in duodenum and multiple intrahepatic lesions, resembling the appearance of metastatic gastrinoma. The octreotide scan gave identical results. The parathyroid SPECT scans showed abnormal concentrations of radioactivity in right parathyroid. She also had an elevated serum chromogranin A (CgA) level. There was medical evidence to show that she is metastatic MEN1. Although multiple liver metastases, they were considered to be resectable after MDT consultation. The intraoperative exploration found a 1.5 cm tumor on the surface of the tail of the pancreas, a 12 cm retroperitoneal lipoma and two liver metastases, sized 3.5 cm and 1.5 cm, respectively. All these tumors were completely removed. For pancreatic tumor, pathological findings met the diagnostic criteria of neuroendocrine tumor (NET) (G2). Immunohistochemistry revealed neuroendocrine areas were diffusely positive for ATRX, DAXX, SSR2, SSR5 and CgA. For lipoma, the FISH results were negative for CDK4 and MDM2 genes. Postoperatively, adjuvant therapy with octreotide was applied. This case suggested that, as for metastatic gastrinoma, a potentially curative surgical debulking should be considered when a resection of complete or more than 90% of metastatic lesions along with the primary site could be achieved, which is helpful to control symptoms and delay the subsequent need for therapy.

BACKGROUND Carcinoid tumor, benign, low-grade malignant, and high-grade malignant, can be associated with the release of vasoactive substances that cause symptoms including cutaneous flushing, diarrhea, and bronchospasm. In 50-60% of patients with carcinoid syndrome, the vasoactive substances cause fibrosis of the pulmonary and tricuspid heart valves which lead to regurgitation and right-sided heart failure. The right side of the heart is usually affected because monoamine oxidases in the lungs usually inactivate the vasoactive substances. CASE REPORT A 62-year-old woman presented with a four-month history of diarrhea and abdominal discomfort. The patient had bilateral pelvic masses and elevated serum CA125 and an elevated urinary 5-hydroxyindoleacetic acid (5-HIAA). Total abdominal hysterectomy (TAH) and bilateral salpingo-oophorectomy (BSO) identified a primary appendiceal carcinoid tumor with bilateral ovarian metastases. Post-operatively, a computed tomography (CT) scan showed cardiomegaly. Transthoracic echocardiography showed morphologic changes that affected all four heart valves, consistent with carcinoid heart disease but without a patent foramen ovale (PFO). The patient was evaluated for valve replacement surgery, but surgery was not performed due to the degree of heart failure. CONCLUSIONS This report describes a rare case of carcinoid heart disease with involvement of all four cardiac valves, but without the presence of a PFO, possibly due to a large amount of vasoactive substances in the patient's circulation, as supported by the patient's elevated urinary 5-HIAA. This rare presentation highlights the importance of early diagnosis and treatment with tumor resection and, if possible, Cardiac valve replacement to prevent irreversible heart failure.
