This study investigated the distribution and chemical coding of neurons in intramural ganglia of the urinary bladder trigone (UBT-IG) and cervix (UBC-IG) in the male pig using combined retrograde tracing and double-labelling immunohistochemistry. Additionally, immunoblotting was used to confirm the presence of marker enzymes for main populations of autonomic neurons. Retrograde fluorescent trac...
BACKGROUND Behcet's disease (BD) is a multisystem disease of unknown etiology. There are several clues which may indicate an ethiopathogenesis role for Helicobacter pylori infection in this disease. METHODS In a case control study in an out patient department, 48 patients with BD were compared to age, sex matched controls regarding presence of H. pylori infection by serology and urea breath t...
We present a two-parameter survival distribution that has an upside-down bathtub (UBT, or humped-shaped) hazard function. This distribution provides biostatisticians, reliability engineers, and other statisticians with a second two-parameter UBT model whose closedform survivor function simplifies the analysis of right-censored data sets. We develop the distribution’s probabilistic and statistic...
Patients with atrophic corpus gastritis and elevated Helicobacter pylori antibody titers but 13C-urea breath test (13C-UBT) and histology results negative for H. pylori were randomized into eradication therapy or follow-up only. Antibody levels decreased significantly in six out of seven patients in the eradication group, while in the follow-up group, the titers declined in only one out of eigh...
The prevalence of Helicobacter pylori infection in a population-based sample of 477 children (mean age plus minus standard deviation, 5.8 plus minus 0.5 years) determined by the [(13)C]urea breath test ([(13)C]UBT) was 10.7% (95% confidence interval [CI], 8.1 to 13.8%), and that determined by salivary enzyme-linked immunosorbent assay (ELISA) was 11.9% (95% CI, 9.2 to 15.2%). Compared to the [(...
OBJECTIVES Rural Alaska Natives have a high prevalence of iron deficiency and Helicobacter pylori infection. The objective of this study was to estimate the prevalence of iron deficiency, iron-deficiency anemia, and active H pylori infection among school-aged children in rural Alaska. METHODS We enrolled 68% (688) of the 7- to 11-year-old children from 10 predominantly Alaska Native villages ...
BACKGROUND Gastric Helicobacter pylori is extremely common worldwide. OBJECTIVES The aim of this study was to assess the effectiveness of combination of Nigella sativa and honey (Dosin) in eradication of gastric H. pylori infection. PATIENTS AND METHODS Nineteen patients who had positive result for H. pylori infection by urea breath test (UBT) without a past history of peptic ulcer, gastric...
OBJECTIVE To compare the current non-invasive tests for Helicobacter pylori infection in children and adolescents. STUDY DESIGN This multicenter, multinational study investigated the sensitivity, specificity, and positive and negative predictive values of four non-invasive tests: urea breath test (UBT), stool antigen test, and antibody detection in serum and urine, in comparison with biopsy-b...
INTRODUCTION This study consisted in the comparison of the prevalence of Helicobacter pylori (H. pylori) present in the stomach and in saliva of a sample of Portuguese adolescents and the assessment of the association between H. pylori infection with socio-demographic variables and prevalence of dental caries. MATERIALS AND METHODS A cross-sectional study was designed including a sample of 44...
BACKGROUND Current diagnostic tests for Helicobacter pylori are invasive (endoscopy) or indirect (urea breath test, serology). AIMS To evaluate a new enzyme immunoassay (EIA) which detects H pylori antigens in faeces, by comparing its sensitivity and specificity in children with the (13)C urea breath test (UBT). METHODS A total of 119 children underwent a UBT and provided a faecal sample fo...
