We used a simple questionnaire to determine the presence or absence of symptoms of gastroesophageal reflux disease (GERD) among control (n=531) and diabetic patients (n=629). Of 531 controls, 24.3% reported having symptoms, while 24.9% of 629 diabetic patients had symptoms. Symptomatic diabetic patients (n=157) were then asked to complete a supplemental questionnaire (QUEST) to determine the frequency, severity, and duration of GERD symptoms; a total diagnostic score > or =4 was considered to be positive for GERD. Diabetic patients whose QUEST score was > or =4 had a significantly higher BMI (26.9+/-0.4* vs. 24.4+/-0.4), higher HbA1c (7.5+/-0.2* vs. 7.2+/-0.1), longer duration of diabetes (113.5+/-8.7* vs. 94.0+/-10.6 months), and a higher prevalence of diabetic complications (retinopathy, 24.8%* vs. 21.3%; nephropathy, 32.6%* vs. 19.4%; neuropathy, 30.4%* vs. 23.6%) than diabetic patients whose QUEST score was <4 (*p<0.05). In diabetic patients with GERD, therapy should include not only proton pump inhibitor therapy and other specific measures for GERD, but also appropriate therapy for the diabetes, particularly blood glucose control and weight reduction.

Patients with diabetes often have gastrointestinal symptoms, but the extent and severity of this problem and the specificity of the symptoms are not nearly as well defined as frequently assumed. Any part of the gastrointestinal tract can be affected, and the presenting symptoms depend on the composite of dysfunctional elements. Gastroesophageal reflux, Candida esophagitis, gastroparesis, diarrhea and constipation are among the many common gastrointestinal complications of diabetes. No specific risk factor for the development of these complications has been identified and their etiology is most likely to be multifactorial, involving both reversible and irreversible processes. Treatment should be directed at tighter glycemic and symptom control, which can bring about clinical improvement for many patients. For other patients, however, effective clinical management is problematic because no therapies are available to prevent or correct the underlying disease mechanisms. Studies now suggest that reduced levels of key trophic factors cause transdifferentiation of pacemaker interstitial cells of Cajal into a smooth-muscle-like phenotype. If this really is the case, therapies directed at restoring the normal milieu of trophic signals could correct the dysfunction of the interstitial cells of Cajal and resolve many gastrointestinal complications. Advances in stem cell technology also hold promise to provide a cure for diabetes and to correct abnormalities in gastrointestinal pathology.

Although the concept of purinergic signalling arose from experiments designed to find the identity of the non-adrenergic, non-cholinergic (NANC) inhibitory neurotransmitter in the gut, it has taken many years for the more general importance of the various roles of ATP as a physiological messenger in the gut to be recognized. Firstly, vasoactive intestitial polypeptide (VIP) and later nitric oxide (NO) were considered the NANC transmitter and it was only later, after the concept of cotransmission was established, that ATP, NO and VIP were recognized as cotransmitters in NANC nerves, although the proportions vary in different gut regions. Recently, many purinoceptor subtypes have been identified on myenteric, submucosal motor, sensory and interneurons involved in synaptic neurotransmission and neuromodulation and reflex activity of several kinds, including ascending excitatory and descending inhibitory reflex pathways. Nucleotide receptors have been shown to be expressed on enteric glial cells and interstitial cells of Cajal. Purinergic mechanosensory transduction, involving release of ATP from mucosal epithelial cells during distension to stimulate subepithelial nerve endings of intrinsic and extrinsic sensory nerves to modulate peristalsis and initiate nociception respectively, is attracting current attention. Exciting new areas of interest about purinergic signalling in the gut include: involvement of purines in development, ageing and regeneration, including the role of stem cells; studies of the involvement of nucleotides in the activity of the gut of invertebrates and lower vertebrates; and the pathophysiology of enteric purinergic signalling in diseases including irritable bowel syndrome, postoperative ileus, oesophageal reflux, constipation, diarrhoea, diabetes, Chaga's and Hirschprung's disease.

The risk factors of cardiovascular disease and other disease comorbidities appear to be more common in patients with psoriasis compared with the general population. To support this concept, the association between psoriasis and cardiovascular disease and other comorbidities was analyzed using data collected from 40 730 patients in the National Health and Wellness Survey (NHWS) during May and June 2004. A case-control study was conducted with data from 1127 patients with psoriasis and a matched cohort of nonpsoriasis patients. Psoriasis patients were significantly more likely to have cardiovascular comorbidities, including hypertension, hypercholesterolemia, and diabetes, compared with nonpsoriasis patients. Other comorbidities significantly associated with psoriasis were arthritis, depression, sleep disorder/insomnia, chronic obstructive pulmonary disease, and gastroesophageal reflux disease. Responses to this large survey confirm that patients with psoriasis have a higher rate of cardiovascular risk factors and other comorbidities compared with patients without psoriasis.

The prevalence of hyponutrition in cystic fibrosis is high although it may vary according to the different studies. Detection of hyponutrition should be done by combining different methods, depending on their availability. However, the simplest and most validated criterion is to measure at each visit the weight (and height in children) in order to calculate the body mass index and categorizing hyponutrition according to absolute criteria: in adults < 18.5 kg/m(2), and in children as percentiles of the body mass index. Worsening of the nutritional status is directly related with the decrease in lung function parameters and it has been proposed as a morbidity (and even mortality) predictive factor in people with cystic fibrosis, independently of the level of pulmonary dysfunction. Exocrine pancreatic insufficiency is present is approximately 70-90% of the patients with cystic fibrosis and the genotype-phenotype correlation is high. Most of the patients with exocrine pancreatic insufficiency tolerate a high-fat diet provided that they are treated with pancreatic enzymes at appropriate doses. The prevalence of diabetes increases with age, reaching up 40% of the cases in patients older than 30 years. Clinical liver involvement is less prevalent (it approximately affects 1/3 of the patients). Other intestinal complications such as meconial ileus, gastroesophageal reflux, obstruction of the distal intestine, or fibrosing colon disease may also condition malnourishment. In patients with cystic fibrosis, a usual high-fat diet providing 120%-150% of the recommended calories is advised. If the nutritional goals are not achieved or maintained with diet modifications, artificial supplements may be added, although the recommendation for their use has not been endorsed by solid scientific evidences. The most frequently used preparations usually are polymeric or hypercaloric. The indications for enteral (through a tube, especially gastrostomy) or parenteral nutritional support are similar to those used in other pathologies. Dietary and nutritional control should be included in a multidisciplinary program allowing the improvement of the functional capacity and the quality of life and reducing, at least from a theoretical viewpoint, the morbimortality associated to malnourishment in these patients.

Laparoscopic Roux-en-Y gastric bypass (LGB) is one of the most popular surgeries for morbid obesity. Robotic use is also on the rise. Data concerning outcomes is limited, hence the need for more information. The first 100 robotic-assisted bypasses by one surgeon in one institution were studied. Data obtained from clinic notes and hospital records included all who underwent the procedure. There were 79 females and 21 males. Mean age and body mass index were 42 years and 48 kg/m2, respectively. Comorbidities included diabetes, 22 per cent; hypertension, 47 per cent, gastroesophageal reflux disease, 40 per cent; obstructive sleep apnea, 53 per cent; dyslipidemia, 17 per cent; and heart disease, 8 per cent. Prior surgeries included cesarean -section, 26 per cent; cholecystectomy, 17 per cent; hysterectomy, 3 per cent; hernia, 1 per cent, and other abdominal surgery, 27 per cent. Intraoperatively procedures included adhesiolysis, 22 per cent; cholecystectomy, 16 per cent; and herniorrhaphy, 3 per cent. Average time was 177.7 minutes. Mean stay was 1.51 days. Thirty-day mortality was 0. Emergency department re-evaluations included 13. Most were minor problems. There was one gastrojejunal leak. Early complications included leak, thrombosis, and bleeding requiring transfusion in four patients. There were four strictures. Overall follow up was greater than 90 per cent. Average weight loss was 21.2 per cent of excess body weight by Month 1, 33.8 per cent by Month 3, and 50.7 per cent by Month 6. Learning curves for time and major complications were 30 and 50 cases, respectively (P = 0.03, 0.04). Robotic use in bariatrics is possible in community hospitals. Although technologies are still in their infancy, complication rates and weight loss are comparable to nonrobotic procedures.

Lung disease in advanced stages is often accompanied by multiple comorbidities. Often, these processes lead to significant morbidity and occasionally mortality. Symptoms of pulmonary comorbidities, including pulmonary embolus, pulmonary hypertension, sleep-disordered breathing, and lung malignancy, may be intertwined with symptoms of advancing lung disease. However, the occurrence of extrapulmonary processes, including depression, diabetes mellitus, osteoporosis, and gastroesophageal reflux disease, may be subtle. Clinicians caring for advanced lung disease should be aware of the many comorbid processes that may accompany advancing lung disease.

Dietary fiber intake provides many health benefits. However, average fiber intakes for US children and adults are less than half of the recommended levels. Individuals with high intakes of dietary fiber appear to be at significantly lower risk for developing coronary heart disease, stroke, hypertension, diabetes, obesity, and certain gastrointestinal diseases. Increasing fiber intake lowers blood pressure and serum cholesterol levels. Increased intake of soluble fiber improves glycemia and insulin sensitivity in non-diabetic and diabetic individuals. Fiber supplementation in obese individuals significantly enhances weight loss. Increased fiber intake benefits a number of gastrointestinal disorders including the following: gastroesophageal reflux disease, duodenal ulcer, diverticulitis, constipation, and hemorrhoids. Prebiotic fibers appear to enhance immune function. Dietary fiber intake provides similar benefits for children as for adults. The recommended dietary fiber intakes for children and adults are 14 g/1000 kcal. More effective communication and consumer education is required to enhance fiber consumption from foods or supplements.

Careful selection of bariatric patients is critical for successful outcomes. In 1991, the NIH first established patient selection guidelines; however, some surgeons operate on individuals outside of these criteria, i.e., extreme age groups. We developed appropriateness criteria for the spectrum of patient characteristics including age, BMI, and severity of eight obesity-related comorbidities. Candidate criteria were developed using combinations of patient characteristics including BMI: > or =40 kg/m(2), 35-39, 32-34, 30-31, <30; age: 12-18, 19-55, 56-64, 65+ years old; and comorbidities: prediabetes, diabetes, hypertension, dyslipidemia, sleep apnea, venous stasis disease, chronic joint pain, and gastroesophageal reflux (plus severity level). Criteria were formally validated on their appropriateness of whether the benefits of surgery clearly outweighed the risks, by an expert panel using the RAND/UCLA modified Delphi method. Nearly all comorbidity severity criteria for patients with BMI > or =40 kg/m(2) or BMI = 35-39 kg/m(2) in intermediate age groups were found to be appropriate for surgery. In contrast, patients in the extreme age categories were considered appropriate surgical candidates under fewer conditions, primarily the more severe comorbidities, such as diabetes and hypertension. For patients with a BMI of 32-34, only the most severe category of diabetes (Hgb A1c >9, on maximal medical therapy), is an appropriate criterion for those aged 19-64, whereas many mild to moderate severity comorbidity categories are "inappropriate." There is overwhelming agreement among the panelists that the current evidence does not support performing bariatric surgery in lower BMI individuals (BMI <32). This is the first development of appropriateness criteria for bariatric surgery that includes severity categories of comorbidities. Only for the most severe degrees of comorbidities were adolescent and elderly patients deemed appropriate for surgery. Patient selection for bariatric procedures should include consideration of both patient age and comorbidity severity.

We reviewed articles on the epidemiology and clinical characteristics of gastroesophageal reflux disease (GERD) in Japan to clarify these features of GERD in this country. Although the definition of GERD depends on the individual study, the prevalence of GERD has been increasing since the end of the 1990s. The reasons for the increase in the prevalence of GERD may be due to increases in gastric acid secretion, a decrease in the Helicobacter pylori infection rate, more attention being paid to GERD, and advances in the concept of GERD. More than half of GERD patients had non-erosive reflux disease, and the majority (87%) of erosive esophagitis was mild type, such as Los Angeles classification grade A and grade B. There were several identified risk factors, such as older age, obesity, and hiatal hernia. In particular, mild gastric atrophy and absence of H. pylori infection influence the characteristics of GERD in the Japanese population. We also discuss GERD in the elderly; asymptomatic GERD; the natural history of GERD; and associations between GERD and peptic ulcer disease and H. pylori eradication. We examined the prevalence of GERD in patients with specific diseases, and found a higher prevalence of GERD, compared with that in the general population, in patients with diabetes mellitus, those with obstructive sleep apnea syndrome, and those with bronchial asthma. We provide a comprehensive review of GERD in the Japanese population and raise several clinical issues.
