Incomplete intestinal absorption of fructose might lead to abdominal complaints such as pain, flatulence and diarrhoea. Whether defect fructose transporters such as GLUT5 or GLUT2 are involved in the pathogenesis of fructose malabsorption is a matter of debate. The hydrogen production by colonic bacteria is used for diagnosis with the hydrogen breath test. However, the appropriate fructose test...
BACKGROUND Hydrogen breath tests are noninvasive procedures frequently applied in the diagnostic workup of functional gastrointestinal disorders. Here, we review hydrogen breath test results and the occurrence of lactose, fructose and sorbitol malabsorption in pediatric patients; and determine the significance of the findings and the outcome of patients with carbohydrate malabsorption. METHOD...
OBJECTIVE To present data on drinking and driving in the city of São Paulo, Brazil, and the effects of the new traffic law (Law 11,705) introduced in 2008. METHODS A cross-sectional study was performed using a questionnaire and passive breath test data to study the prevalence of drinking and driving and the association of drinking and driving with background characteristics and drinking patte...
AIMS To determine the breath alcohol elimination rate (AER) and Widmark factor derived from the maximum breath alcohol concentration (r(peak BrAC)) in Chinese and Indians in Singapore, and to evaluate the contribution of genetic and non-genetic factors to variability of AER and r(peak BrAC). METHODS A total of 180 subjects ingested a vodka-orange juice mixture, together with a standardized me...
Thirty-eight infants and young children with gastroenteritis were investigated for lactose malabsorption. Each of them was given an oral lactose load of either 0.5 g/kg or 2 g/kg after which breath hydrogen excretion was measured, and each was observed to see if he had clinical symptoms of lactose intolerance. Only one patient, given 2 g/kg lactose, had clinical intolerance. His breath hydrogen...
Background/Aims Fructose malabsorption (FM) mimics symptoms of irritable bowel syndrome (IBS), and its prevalence has increased. Diagnosing FM in IBS is challenging because of its overlap with small intestinal bacterial overgrowth (SIBO). We assessed the prevalence of FM by comparing patients with IBS with asymptomatic control individuals after excluding SIBO using the glucose hydrogen breath t...
Measuring the concentration of alcohol in body fluids represents a large part of the workload at forensic science and toxicology laboratories. In traffic-law enforcement, breath-alcohol testing is used worldwide for roadside screening and for evidential purposes. Many jurisdictions have adopted per se laws which make it a crime to drive with a blood- or breath-alcohol concentration above a pres...
UNLABELLED Fructose malabsorption has not been well-defined in Thai populations but there has been increasing consumption of fructose-fortified drinks. OBJECTIVES To assess the incidence of fructose malabsorption and intolerance in Thai normal subjects as well as the facilitating effect of glucose on fructose absorption. METHODS Twenty-five gram of fructose was ingested by 77 subjects (37 m...
BACKGROUND The (13)C-octanoic acid breath test is a convenient method for assessing gastric emptying (GE). Success depends on obtaining a well-characterized time profile of the excretion of label in breath, which may not be the case if GE is delayed. AIMS To use Bayesian techniques in conjunction with hierarchical modelling as a method to increase the success of the modelling process. METHO...
