Dyspepsia in infants and children

Asymptomatic Duodenitis and Helicobacter pylori associated Dyspepsia in 2-Year-Old Chronic Malnourished Bangladeshi Slum-Dwelling Children: A Cross-Sectional Study

AIM

There is insufficient knowledge on the * duodenal histology and Helicobacter pylori infection in malnourished Bangladeshi children. Therefore, we attempted to explore the prevalence of H. pylori infection and duodenal histopathology in 2-year-old chronic malnourished Bangladeshi slum-dwelling children and investigate their association with dyspeptic symptoms.

METHODS

This cross-sectional study was conducted using the data of the Bangladesh Environmental Enteric Dysfunction study in an urban slum of Dhaka, Bangladesh. With a view to address the association of environmental enteric dysfunction (EED) with stunting, upper gastrointestinal endoscopy was performed on 54 chronic malnourished children {31 stunted [length-for-age Z-scores (LAZ) <-2] and 23 at risk of stunting (LAZ <-1 to -2)} aged between 12-24 months and the mucosal biopsies were subjected to histopathological examination after obtaining proper clinical history. Stool antigen for H. pylori (HpSA) was assessed to determine H. pylori status.

RESULTS

In all, 83.3% (45/54) of the children had histopathological evidence of duodenitis. Chronic mild duodenitis was found to be the most prevalent form of duodenitis (53.7%) in the children. Only 8.9% (4/45) of the children with duodenitis had dyspepsia (p < 0.05). The 14.8% (8/54) of the children were found positive for H. pylori infection. Logistic regression analysis revealed children positive for HpSA had significant association with dyspepsia (OR 9.34; 95% CI 1.54-56.80).

CONCLUSIONS

The number of chronic malnourished children suffering from duodenitis was found to be very high. Majority of these children was asymptomatic. Children positive for HpSA had significant association with dyspeptic symptoms.

Multidimensional measure for gastroesophageal reflux disease (MM-GERD) symptoms in children: a population-based study

BACKGROUND

Gastroesophageal reflux disease (GERD) symptoms are very common in children with major presenting symptoms of abdominal pain, heartburn and regurgitation. The presence of GERD symptoms often result in an impaired health-related quality of life for both the patients and their parents. Evaluation of children with GERD symptoms continues to challenge physicians due to the lack of a validated measure for GERD symptoms.

AIMS

To develop and test a multidimensional measure for GERD symptoms in children and to evaluate the responses of the measure among children attending pediatric gastroenterology (GI) clinics.

METHODS

We conducted a cross-sectional study that enrolled children with GERD symptoms from pediatric GI clinic. All children and parents received a standardized questionnaire concerning socio-economic parameters, GERD symptoms, duration, frequency, intensity and missed activities due to GERD symptoms. Each child and parent pair was interviewed by a physician to complete baseline information for the multidimensional measure that consisted of four scales: symptoms scale (10 items), pain intensity scale (3 items); disability scale (3 items) and satisfaction scale (2 items).

RESULTS

One hundred and thirty-three children participated in the study; 59% girls, ages 4 to 18 years, mean age = 10 +/- 3, 50%, 10 years and younger. There was an excellent correlation between the four-scales measure among children 7 years and younger (R = 0.70, p = 0.0001) and children >7 years (R = 0.74, p = 0.0001). The inter-item consistency (Cronbach's co-efficient alpha) for the symptoms items, pain intensity items, disability items and satisfaction items were 0.71, 0.74, 0.78 and 0.60, respectively, demonstrating adequate reliability of the measure.

CONCLUSION

Children with GERD symptoms have good responses to the multidimensional measure for GERD symptoms, showing that the measure performed well across populations. The measure is reliable and specific for assessing the symptoms of GERD in children and is an appropriate outcomes measure for clinical trials involving GERD symptoms in children.

Infusionstherapie und Ernährung von Risikogruppen

Besondere Situationen erfordern ein besonderes Vorgehen. Während bisher das »Standardvorgehen« bezüglich der Ernährung von pädiatrischen Patienten dargestellt wurde, beschäftigt sich das vorliegende Kapitel mit »Sondersituationen« der pädiatrischen Infusionstherapie und Ernährung. Behandlungssituationen, die ein besonderes Vorgehen bei der Therapie oder spezielle Aufmerksamkeit bei der Anpassung der Ernährung erfordern, entstehen in der Regel durch 4 mögliche Situationen:

spezifische Physiologie von Patientengruppen (z. B. Früh- oder Neugeborene),

Auswirkungen von therapeutischen Maßnahmen (z. B. Operationen),

Pathophysiologie von Erkrankungen (z. B. angeborene Stoffwechselerkrankungen, Erkrankungen des onkologischen, rheumatischen oder atopischen Formenkreises, Anorexia nervosa, Bulimie oder Adipositas) oder

besondere körperliche Belastungen [z. B. (Leistungs-)Sport].

Bekannte Strategien werden systematisch und prägnant dargestellt und diskutiert.

Die Beschäftigung mit der Ernährung von »Risikogruppen« übt das Erkennen und den Umgang von potenziellen Gefahrensituationen bei der Verordnung von bilanzierter Ernährung. So sollte auch derjenige von dem Kapitel profitieren, der sich mit den behandelten Patientengruppen, Situationen, Erkrankungen üblicherweise nicht beschäftigen muss.

[Biliary lithiasis in childhood: therapeutic approaches]

Until recently, biliary lithiasis was considered infrequent in childhood. According to their composition, gallstones can be classified into cholesterol stones and pigment stones. The latter are mainly composed of calcium salts of unconjugated bilirubin and are divided into hard black and soft brown stones. In children, up to 75 % of gallstones are pigment stones. Their etiology is often unknown. Biliary lithiasis in children differs from that in adults and there is very little scientific evidence on the most suitable therapeutic procedures. Symptom-free stones usually have a benign course and do not require medical or surgical treatment. Symptoms are often nonspecific and include dyspepsia and chronic abdominal pain. These symptoms are an indication for ultrasonographic scan to rule out the presence of gallstones. Cholecystectomy is the definitive treatment for gallstones but is not always indicated. Medical treatment with ursodeoxycholic acid is indicated in oligosymptomatic and asymptomatic lithiasis with transparent, soft, cholesterol-rich stones and a functional bladder and in patients with a high surgical risk.

Gastro-oesophageal reflux in infants: an evidence-based approach

Gastro-oesophageal reflux (GOR) is present in most infants, but is usually a benign condition that resolves by the age of 6 to 12 months as the gastrointestinal tract develops. While it lasts, however, reflux symptoms can be very worrying for parents, and community nurses are well placed to provide them with reassurance, support and advice on practical measures that will improve symptoms in most cases. Nurses also have an essential role in monitoring infants for possible progression of symptoms to complicated GOR or gastro-oesophageal reflux disease (GORD), and in ensuring that such babies, and those with a possible underlying abnormality, receive appropriate referral for further investigation and medical or surgical treatment.

Abdominal migraine: evidence for existence and treatment options

There is evidence to suggest that, in children, episodic abdominal pain occurring in the absence of headache may be a migrainous phenomenon. There are four separate strands of evidence for this: the common co-existence of abdominal pain and migraine headaches; the similarity between children with episodic abdominal pain and children with migraine headaches, with respect to social and demographic factors, precipitating and relieving factors, and accompanying gastrointestinal, neurological and vasomotor features; the effectiveness of nonanalgesic migraine therapy (such as pizotifen, propanolol, cyproheptadine and the triptans) in abdominal migraine; and the finding of similar neurophysiological features in both migraine headache and abdominal migraine. Abdominal migraine is rare, but not unknown, in adults. Many families are content with a diagnosis and reassurance that the episodes, though distressing, are not the result of serious pathology. Some patients respond to simple dietary and other prophylactic measures. There is scant evidence on which to base recommendations for the drug management of abdominal migraine. What little literature exists suggests that the antimigraine drugs pizotifen, propanolol and cyproheptadine are effective prophylactics. Nasal sumatriptan (although not licensed for pediatric use) may be effective in relieving abdominal migraine attacks.

Techniques for the evaluation of dyspepsia in children

Dyspepsia can describe a subset of children with episodic or persistent abdominal symptoms--often related to feeding--that are thought to be caused by disorders of the proximal part of the digestive tract. Symptoms, such as vomiting, early satiety, postprandial epigastric abdominal pain, heartburn, abdominal fullness, poor weight gain, and/or anorexia, have been incorporated into the definition of dyspepsia. Unfortunately, presenting signs and symptoms in children with dyspepsia are nonspecific and can occur as a result of many diseases, such as parasitic infections, esophagitis, eosinophilic gastroenteritis, Helicobacter pylori infection, Crohn's disease, biliary tract or hepatic disease, pancreatitis, and lactose intolerance. This lack of specificity makes the evaluation of dyspepsia more difficult. Here, we describe an approach for the evaluation of dyspepsia that correlates in part with the child's presenting symptoms.
