The new millennium has seen distinct changes in the pattern of gastrointestinal disease in the Asia-Pacific region. These changes are important as more than half of the world's population come from the region and therefore impact significantly on the global disease burden. The highest incidence of gastric cancer (GCA) has been reported from Asia and GCA remains a very important cancer. However time-trend studies have shown a decrease in GCA incidence in several countries in Asia. A rise in cardio-esophageal cancers as seen in the West has not been reported. On the other hand, colorectal cancer has been steadily increasing in Asia with age-standardized incidence rates of some countries approaching that of the West. The pattern of acid-related diseases has also changed. Gastroesophageal reflux disease is a fast emerging disease with an increasing prevalence of reflux esophagitis and reflux symptoms. The prevalence of peptic ulcer disease has at the same time declined in step with a decrease in H. pylori infection. Many of the changes taking place mirror the Western experience of several decades ago. Astute observation of the epidemiology of emerging diseases combined with good scientific work will allow a clearer understanding of the key processes underlying these changes. With rapid modernization, lifestyle changes have been blamed for an increase in several diseases including gastroesophageal reflux disease, nonalcoholic fatty liver disease and colorectal cancer. A worrying trend has been the increase in obesity among Asians, which has been associated with an increase in metabolic diseases and various gastrointestinal cancers. Conversely, an improvement in living conditions has been closely linked to the decrease in GCA and H. pylori prevalence.

Sandifer's syndrome is a gastrointestinal disorder with neurological features. It is characterized by reflex torticollis following deglutition in patients with gastroesophageal reflux and/or hiatal hernia. The authors believe that neurological manifestations of the syndrome are the consequence of vagal reflex with the reflex center in nucleus tractus solitarii (NTS). Three models for the neuroanatomical basis of the hypothetic reflex arc are presented. In the first one the hypothetic reflex arc is based on the classic hypothesis of two components nervus accessorius (n.XI) - radix cranialis (RC) and radix spinalis (RS) The nervous impulses are transmitted by nervus vagus (n.X) general visceral afferent (GVA) fibers to NTS situated in medulla oblongata, then by interneuronal connections on nucleus ambiguus (NA) and nucleus dorsalis nervi vagi (NDX). Special visceral efferent fibers (SVE) impulses from NA are in part transferred to n.XI ramus externus (RE) (carrying the majority of general somatic efferent (GSE) fibers) via hypothetic anastomoses in the region of foramen jugulare. This leads to contraction of trapezius and sternocleidomastoideus muscles, and the occurrence of intermittent torticollis. In the second suggested neuroanatomical model the hypothetic reflex arc is organized in the absence of n.XI RC, the efferent part of the reflex arc continues as NA, which is motor nucleus of nervus glossopharyngeus (n.IX) and n.X in this case while distal roots of n.XI that appear at the level of the olivary nucleus lower edge represent n.X roots. In the third presented model the hypothetic reflex arc includes no jugular transfer and could be realized via interneuronal connections directly from NTS to the spinal motoneurons within nucleus radicis spinalis nervi accessorii (NRS n.XI) or from NA to NRS n.XI. The afferent segment of the postulated reflex arc in all three models is mediated via n.X. We conclude that Sandifer's syndrome is a clinical manifestation of another vagal reflex that could be termed a "vagocervical" or "esophagocervical" reflex, based on the neuroanatomical hypotheses elaborated in this paper.

Functional dyspepsia (FD) is a highly prevalent gastrointestinal disorder characterized by symptoms originating from the gastroduodenal region in the absence of underlying organic disease that readily explains the symptoms. The Rome II consensus, which defined FD as the presence of unexplained pain or discomfort in the epigastrium, had a number of drawbacks, including an unjustified focus on pain, inclusion of a large number of nonspecific symptoms, and an unclear position on overlap with gastroesophageal reflux disease (GERD) and irritable bowel syndrome (IBS). The Rome III consensus redefined FD as the presence of epigastric pain or burning, postprandial fullness or early satiation in the absence of underlying organic disease. Frequent overlap with GERD and IBS is acknowledged but does not exclude a diagnosis of FD. A subgroup classification into postprandial distress syndrome and epigastric pain syndrome was proposed. Ongoing studies will clarify the impact of this subdivision on clinical management and treatment outcomes.

Up to 79% of IBS patients report gastroesophageal reflux disease (GERD) symptoms, and up to 71% of GERD patients report irritable bowel syndrome (IBS) symptoms. There are two principal hypotheses for the common presence of IBS symptoms in GERD patients. The first theory suggests that GERD and IBS overlap in a significant number of patients. The second theory suggests that IBS-like symptoms are part of the spectrum of GERD manifestation. The first theory is supported by genetic studies and similarities in gastrointestinal sensory-motor abnormalities potentially due to general gastrointestinal disorder of smooth muscle or sensory afferents. The other theory is primarily supported by studies demonstrating improvement of IBS-like symptoms in GERD patients receiving anti-reflux treatment. The close relationship between GERD and IBS could be explained by either GERD affecting different levels of the GI tract or a high overlap rate between GERD and IBS due to similar underlying GI dysfunction.

It is known that the predisposition to human disease is a mixture of inherited susceptibility and acquired exposure to environmental factors. Understanding gastrointestinal disease has indicated that germline adenomatous polyposis coli mutations predispose with a 99% certainty to colorectal cancer, whereas squamous esophageal cancer is caused by a combination of environmental exposures (including alcohol consumption, cigarette smoke, ingestion of contaminated preserved food) and/or infection (specifically with human papilloma virus), in most cases. Until now, despite the reasonably strong evidence for genetic risk from monozygotic twin studies for gastro-esophageal reflux disease (GERD), there have been no documented genetic targets in GERD. In this edition of the Journal, there is intriguing evidence that a common, single base-pair change in the secondary messenger gene GNbeta3 (i.e., a single-nucleotide polymorphism) may be important, perhaps through promoting abnormal perception of visceral pain in the esophagus. Other works link this genetic factor to functional dyspepsia, and these exciting preliminary lines of evidence are reviewed.

GERD is a common chronic gastrointestinal disorder, and its prevalence in Asia is increasing. Classical symptoms of heartburn and regurgitation are common presentations. There is no standard criterion for the diagnosis of GERD, and 24-h pH monitoring lacks sensitivity in NERD. Furthermore, diagnostic studies for gastroesophageal reflux disease have several limitations. A short course of PPI is often used in clinical practice as a diagnostic test for gastroesophageal reflux disease. Elderly patients with GERD usually present with atypical manifestations, and they tend to develop more severe disease. PPI remains the mainstay of treatment for GERD. In a subset of patients who wish to discontinue maintenance treatment, anti-reflux surgery is a therapeutic option.

Recent data suggest that, contrary to initial expectations with improvements in perinatal medicine, the prevalence of cerebral palsy has not decreased over the last 20 years. Gastrointestinal disorders are a major chronic problem in most of children with cerebral palsy and in children with neurodevelopmental disabilities. A multidisciplinary approach, with input from neurologists, gastroenterologists, nurses, dieticians and other specialists, can make a major contribution to the medical wellbeing and quality of life of these children and their caregivers. This article focuses on diagnostic methods and therapeutic options available for major nutritional and gastrointestinal problems in patients with neurological disabilities: gastroesophageal reflux, constipation and swallowing disorders.

Gastroesophageal reflux disease (GERD) is the most common upper gastrointestinal disorder seen in the elderly. The worldwide incidence of GERD is increasing as the incidence of Helicobacter pylori is decreasing. Although elderly patients with GERD have fewer symptoms, their disease is more often severe. They have more esophageal and extraesophageal complications that may be potentially life threatening. Esophageal complications include erosive esophagitis, esophageal stricture, Barrett's esophagus and adenocarcinoma of the esophagus. Extraesophageal complications include atypical chest pain that can simulate angina pectoris; ear, nose, and throat manifestations such as globus sensation, laryngitis, and dental problems; pulmonary problems such as chronic cough, asthma, and pulmonary aspiration. A more aggressive approach may be warranted in the elderly patient, because of the higher incidence of severe complications. Although the evaluation and management of GERD are generally the same in elderly patients as for all adults, there are specific issues of causation, evaluation and treatment that must be considered when dealing with the elderly.
