Over a 2-year period, 34 children were referred to the division of pediatric gastroenterology at the University of Virginia with chronic upper gastrointestinal symptoms whose symptoms rapidly and completely resolved when their unrecognized constipation was treated. The average age at presentation was 8.24 (SD 0.78) years and average duration of upper intestinal symptoms was 15.6 (SD 3.5) months. Twenty-six of 34 had experienced recurrent vomiting, 6 complained of chronic nausea, 17 had chronic symptoms of gastroesophageal reflux, and 20 complained of chronic or recurrent abdominal pain, most often in the epigastric region. Smaller numbers had experienced early satiety, choking, gagging, dysphagia, or intermittent diarrhea. Given the prevalence of constipation in childhood, it seems likely that many children who experience chronic upper intestinal symptoms may be suffering from chronic unrecognized constipation as the cause of their upper intestinal symptoms.

The clinical efficacy of probiotics and prebiotics has been proved in several clinical settings. The authors review their proved or potential side effects. Probiotics as living microorganisms may theoretically be responsible for 4 types of side effects in susceptible individuals: infections, deleterious metabolic activities, excessive immune stimulation, and gene transfer. Very few cases of infection have been observed. These occurred mainly in very sick patients who received probiotic drugs because of severe medical conditions. Prebiotics exert an osmotic effect in the intestinal lumen and are fermented in the colon. They may induce gaseousness and bloating. Abdominal pain and diarrhea only occur with large doses. An increase in gastroesophageal reflux has recently been associated with large daily doses. Tolerance depends on the dose and individual sensitivity factors (probably the presence of irritable bowel syndrome or gastroesophageal reflux), and may be an adaptation to chronic consumption.

When no organic cause for dyspepsia is found, the condition generally is considered to be functional, or idiopathic. Nonulcer dyspepsia can cause a variety of symptoms, including abdominal pain, bloating, nausea, and vomiting. Many patients with nonulcer dyspepsia have multiple somatic complaints, as well as symptoms of anxiety and depression. Extensive diagnostic testing is not recommended, except in patients with serious risk factors such as dysphagia, protracted vomiting, anorexia, melena, anemia, or a palpable mass. In these patients, endoscopy should be considered to exclude gastroesophageal reflux disease, peptic or duodenal ulcer, and gastric cancer. In patients without risk factors, consideration should be given to empiric therapy with a prokinetic agent (e.g., metoclopramide), an acid suppressant (histamine-H2 receptor antagonist), or an antimicrobial agent with activity against Helicobacter pylori. Treatment of patients with H. pylori infection and nonulcer dyspepsia (rather than peptic ulcer) is controversial and should be undertaken only when the pathogen has been identified. Psychotropic agents should be used in patients with comorbid anxiety or depression. Treatment of nonulcer dyspepsia can be challenging because of the need to balance medical management strategies with treatments for psychologic or functional disease.

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.

Gastroesophageal reflux disease (GERD) presents in different ways in children, most commonly with vomiting, or with esophageal symptoms such as regurgitation, heartburn, or dysphagia. Extraesophageal symptoms and signs also frequently occur. Less well recognized is that abdominal pain is a relatively common mode of presentation. Although abdominal pain is common in school-aged children, GERD and other acid-related disorders such as peptic ulcer disease are relatively uncommon causes of such. A careful history will usually determine whether an acid-related disorder is in the differential diagnosis of abdominal pain. Early detection and treatment of GERD in children may prevent, attenuate, or heal complications such as failure to thrive or feeding refusal as well as pulmonary, ear-nose-and-throat disorders, erosive esophagitis, and peptic stricture. In children with persistent or severe symptoms and/or complications of GERD such as erosive esophagitis, the major treatment options are pharmacologic management with acid-suppressing medication, specifically proton pump inhibitors (PPIs), or antireflux surgery. For many patients, PPI treatment offers advantages over surgery. When given in adequate doses, PPIs can safely effect relief of GERD symptoms and healing of esophagitis in children. Antireflux surgery may work well in selected patients, but it carries significant risk of morbidity, including high failure rates, even in the short term. Some postoperative studies report that more than 60% of patients are back on medical treatment with proton pump inhibitors for recurrence of GERD symptoms, and a similar percentage have new symptoms that were not present before surgery. Death is uncommon but does occur and is an unacceptable risk in an otherwise healthy, low-risk individual. Laparoscopic surgery may have some disadvantages compared with open surgery, including a higher rate of redo operations. Studies show that many children undergo surgery for unclear indications, often with few preoperative diagnostic studies. The availability of highly effective medical therapy, together with more careful selection of patients for surgery, may result in better patient outcomes, with much lower operative rates.

A survey of advanced practice nurses in the Association of Pediatric Gastroenterology and Nutrition Nurses (APGNN) was conducted to assess role diversity in anticipation of sharing these results with our international colleagues at the World Congress in 2004. A single-page, 14-item survey was sent via e-mail or fax to 79 APGNN advanced practice nurses identified by their credentials (MS, PNP, FNP) in the membership database. Forty surveys were returned via e-mail or fax for an overall response rate of 51%. Most reported working full time as nurse practitioners in an outpatient gastrointestinal clinic, yet almost one third were hospital based. Additional job titles included clinical nurse specialist, researcher, and case manager or clinical coordinator. Slightly more than one half reported seeing any patients in their outpatient practice, whereas 43% saw specific populations, with constipation, gastroesophageal reflux, and abdominal pain being the most common diagnoses. Seventy percent had prescriptive privileges. Billing practices were the most diverse, with 30% always billing under their own number, 23% sometimes billing under their own number, and 40% never billing under their own number (5% not applicable). Overall, most advanced practice nurses in APGNN are pediatric nurse practitioners with a primary focus on outpatient care but also are involved in patient and family teaching, nutrition support, home care, and research. Only a few were involved with procedures, which may be surprising to our adult counterparts.

As an update to previously published recommendations for the management of Helicobacter pylori infection, an evidence-based appraisal of 14 topics was undertaken in a consensus conference sponsored by the Canadian Helicobacter Study Group. The goal was to update guidelines based on the best available evidence using an established and uniform methodology to address and formulate recommendations for each topic. The degree of consensus for each recommendation is also presented. The clinical issues addressed and recommendations made were: population-based screening for H. pylori in asymptomatic children to prevent gastric cancer is not warranted; testing for H. pylori in children should be considered if there is a family history of gastric cancer; the goal of diagnostic interventions should be to determine the cause of presenting gastrointestinal symptoms and not the presence of H. pylori infection; recurrent abdominal pain of childhood is not an indication to test for H. pylori infection; H. pylori testing is not required in patients with newly diagnosed gastroesophageal reflux disease; H. pylori testing may be considered before the use of long-term proton pump inhibitor therapy; testing for H. pylori infection should be considered in children with refractory iron deficiency anemia when no other cause has been found; when investigation of pediatric patients with persistent or severe upper abdominal symptoms is indicated, upper endoscopy with biopsy is the investigation of choice; the 13C-urea breath test is currently the best noninvasive diagnostic test for H. pylori infection in children; there is currently insufficient evidence to recommend stool antigen tests as acceptable diagnostic tools for H. pylori infection; serological antibody tests are not recommended as diagnostic tools for H. pylori infection in children; first-line therapy for H. pylori infection in children is a twice-daily, triple-drug regimen comprised of a proton pump inhibitor plus two antibiotics (clarithromycin plus amoxicillin or metronidazole); the optimal treatment period for H. pylori infection in children is 14 days; and H. pylori culture and antibiotic sensitivity testing should be made available to monitor population antibiotic resistance and manage treatment failures.

The clinical and socioeconomic burden of gastro-esophageal reflux disease (GERD) is considerable. The primary symptom of GERD is heartburn, but it may also be associated with extraesophageal manifestations, such as asthma, chest pain and otolaryngologic disorders. The objective of the study was to describe the impact of heartburn on patients' Health-Related Quality of Life (HRQL) in Poland, using validated generic and disease-specific instruments to measure patient-reported outcomes. Patients with symptoms of heartburn completed the Polish versions of the Gastrointestinal Symptom Rating Scale (GSRS), the Quality of Life in Reflux and Dyspepsia questionnaire (QOLRAD), the Short Form-36 (SF-36) and the Hospital Anxiety and Depression (HAD) scale. Frequency and severity of heartburn during the previous 7 days were also recorded. 135 patients completed the assessments (mean age of 44 years, SD = 15; 61% female). 55% of patients had moderate symptoms and nearly two thirds (64%) had symptoms on 5 or more days in the previous week. Patients were most bothered by symptoms of reflux (mean GSRS score of 4.1, on a scale of 1 [not bothered] to 7 [very bothered]), indigestion (3.5) and abdominal pain (3.2). As a result of their symptoms, patients experienced impaired vitality (mean QOLRAD score of 3.8, on a scale of 1 to 7, where 1 represents the most severe impact on daily functioning), problems with food and drink (3.9), emotional distress (4.1) and sleep disturbance (4.7). Using HAD, 32% of heartburn patients were anxious and 10% were depressed. In conclusion it should be stated that there is consistent evidence that GERD substantially impairs all aspects of health-related quality of life.

Two gastroesophageal reflux disease (GERD) symptom questionnaires were developed and tested prospectively in a pilot study conducted in infants (1 through 11 months) and young children (1 through 4 years) with and without a clinical diagnosis of GERD. A pediatric gastroenterologist made the clinical diagnosis of GERD. Parents or guardians at 4 study sites completed the questionnaires, providing information on the frequency and severity of symptoms appropriate to the 2 age cohorts. In infants, symptoms assessed were back arching, choking or gagging, hiccups, irritability, refusal to feed and vomiting or regurgitation. In young children, symptoms assessed were abdominal pain, burping or belching, choking when eating, difficulty swallowing, refusal to eat and vomiting or regurgitation. Respondents were asked to describe additional symptoms. Symptom frequency was the number of occurrences of each symptom in the 7 days before completion of the questionnaire. Symptom severity was rated from 1 (not at all severe) to 7 (most severe). An individual symptom score was calculated as the product of symptom frequency and severity scores. The composite symptom score was the sum of the individual symptom scores. The mean composite symptom and individual symptom scores were higher in infants (P<0.001 and P<0.05, respectively) and young children (P<0.001 and P<0.05, respectively) with GERD than controls. Vomiting/regurgitation was particularly prevalent in infants with GERD (90%). Both groups with GERD were more likely to experience greater severity of symptoms. We found the GERD Symptom Questionnaire useful in distinguishing infants and young children with symptomatic GERD from healthy children.

The available evidence from randomized clinical trials or meta-analyses on the therapeutic efficacy of psychotropic drugs and, specifically, of antidepressants, in functional gastrointestinal disorders (FGD), are recent and still fairly limited. The use of these drugs is based on the frequent association of anxiety and depression or neurosis in patients with FGD who seek medical care and on the demonstrated efficacy of these drugs in relieving chronic pain, whatever its origin or localization, for more than 30 years. Antidepressants, even in doses under the antidepressant range, are antinociceptive due to their central and peripheral neuromodulatory effect, which is completely independent of anticholinergic, spasmolytic or antidepressant effects. This has been demonstrated in both animals and humans and, as occurs with another antinociceptive drugs such as clonidine, is mediated by alpha-adrenoreceptors. The choice of antidepressant depends both on the evidence of its analgesic activity (in general greater with tricyclic antidepressants than with the more modern selective serotonin reuptake inhibitors) and on the presence of drug-related adverse effects, which include not only anticholinergic adverse effects but also the possibility of hypotension or cardiotoxicity, which should be avoided. The main selection criteria are demonstrated efficacy and safety. Antidepressants have been shown to be effective in the specific field of non-coronary chest pain probably originating in the esophagus unrelated to gastroesophageal reflux disease, especially mianserin and trazodone, and the effect is maintained in the long term in nearly three-quarters of treated patients. Tricyclic antidepressants have also been shown to be effective in the treatment of abdominal pain in patients with irritable bowel syndrome, with an OR of 4.2 and an NNT of 3.2 in comparison with placebo. In contrast, there is insufficient evidence to recommend the use of antidepressants in functional dyspepsia.
