    High-grade vesicoureteral reflux (VUR) in children is associated with recurrent urinary tract infection (UTI) and renal damage. Breakthrough UTI despite continuous antibiotic prophylaxis (CAP) during the first years of life is a matter of concern and evokes early intervention. We investigated whether early endoscopic treatment (ET) of VUR grade 4-5 can reduce the risk of UTI recurrence and renal scarring. This prospective, randomized, controlled, multicentre, 1-year follow-up trial comprised 77 infants, UTIs were reported. There were 27 recurrent febrile UTIs in 6 (16%) children in the ET group and in 10 (26%) in the CAP group (p = 0.43), in eight (36%) girls and eight (15%) boys (p = 0.039). Successful VUR outcome (VUR 0-2) was seen in 22 (59%) in the ET and eight (21%) in the CAP group (p = 0.0014). Multiple recurrences were only seen in patients with persistent dilating reflux at follow-up (p = 0.019). Deterioration on scintigraphy was seen in eight children (9 kidneys) with no difference between treatment groups (p = 0.48) or sex (p = 0.17). Renal deterioration was associated with high bladder capacity (BC) and large residual volume (PVR) at 1 year (p = 0.0092 and p = 0.041). Six of the eight children with renal deterioration had a recurrent UTI (p = 0.0032). Seven of nine renal units with deterioration were seen in children with persistent VUR 3-5 at follow-up. Univariable logistic regression identified female sex and high PVR as positive predictors for recurrent UTI (p = 0.039 and 0.034) and high PVR tended to predict renal deterioration (p = 0.053). No differences between the treatment groups regarding recurrent UTI and renal deterioration could be found. Increased PVR and female sex were positive predictors for UTI recurrences. VUR grade at follow-up was correlated to UTI recurrence and renal deterioration. This study did not show any difference between ET and CAP in reducing the risk of UTI recurrence or renal deterioration. The rate

    BACKGROUND AND OBJECTIVE: Vesicoureteral reflux (VUR) is diagnosed in ∼30% to 40% of children who have imaging studies after urinary tract infections (UTIs). Our goal is to characterize children enrolled in the Randomized Intervention for Children with Vesicoureteral Reflux (RIVUR) trial and to compare our study cohort with those from previously published studies. METHODS: RIVUR investigators from 19 pediatric sites in the United States recruited 607 children with grade I through IV VUR. Children were enrolled after a first or second UTI. This cross-sectional report of baseline data includes extensive clinical, parental report, and imaging study results. RESULTS: RIVUR recruited 607 children (558 girls, 49 boys) with grade I (11%), II (42%), III (38%), or IV (8%) reflux. The median age was 12 months, and most children (91%) were enrolled after their first UTI. The UTI leading to enrollment was both febrile and symptomatic for 323 children, febrile only in 197 children, and symptomatic only in 86. Renal involvement at baseline as documented by a 99mTc dimercaptosuccinic acid scan was uncommon with cortical defects identified in 89 (15%) children. Bladder and bowel dysfunction was identified in 71 (56%) of 126 toilet-trained subjects assessed. CONCLUSIONS: RIVUR is the largest prospective, randomized trial for children with primary VUR to date, comparing prophylaxis with placebo. The study sample comprises patients from 19 pediatric clinical sites in the United States, whose demographic and clinical characteristics may differ from those of children enrolled in previous trials from other countries.

    Gastroesophageal reflux disease lowers the quality of life and increases medical costs. Electroacupuncture has been used to ease symptoms and improve gastrointestinal motility in patients with gastroesophageal reflux disease. The main purposes of this study are to evaluate the efficacy and safety of this procedure. This is a protocol for a randomized, patient-blinded, assessor-blinded, sham-controlled trial. Sixty participants with symptoms of gastroesophageal reflux disease, who have previously undergone standard treatment, will be recruited from August 2015 at Kyung Hee University Korean Medicine Hospital. The participants will be allocated to either the electroacupuncture (n = 30) or the sham electroacupuncture group (n = 30); the allocation will be concealed from both the participants and the assessors. The EA group will undergo penetrating acupuncture at 18 fixed points and two optional points chosen using the pattern identification for gastroesophageal reflux disease. Electrical stimulation will be applied at some of the acupoints. The sham electroacupuncture group will undergo nonpenetrating acupuncture without electrical stimulation at 18 nonspecific points, each of which will be only 2 cm away from the true acupoints used in the electroacupuncture group. In both groups, the procedure will be performed using the Park device. The treatment will last for 6 weeks (with two sessions each week), and the outcome will be evaluated at baseline, 3 weeks, and 6 weeks. The primary outcome will be the proportion of responders with adequate symptom relief, whereas the secondary outcomes will comprise the results of the Nepean dyspepsia index; the Korean gastrointestinal symptom rating scale; the EQ-5D™; levels of gastrin, motilin, and inflammatory cytokines; the perceived stress scale; the qi-stagnation questionnaire; the patient global impression of change; and the spleen qi deficiency questionnaire. The results of this trial will provide information

    Objectives To determine the long term clinical effectiveness of laparoscopic fundoplication as an alternative to drug treatment for chronic gastro-oesophageal reflux disease (GORD). Design Five year follow-up of multicentre, pragmatic randomised trial (with parallel non-randomised preference groups). Setting Initial recruitment in 21 UK hospitals. Participants Responders to annual questionnaires among 810 original participants. At entry, all had had GORD for >12 months. Intervention The surgeon chose the type of fundoplication. Medical therapy was reviewed and optimised by a specialist. Subsequent management was at the discretion of the clinician responsible for care, usually in primary care. Main outcome measures Primary outcome measure was self reported quality of life score on disease-specific REFLUX questionnaire. Other measures were health status (with SF-36 and EuroQol EQ-5D questionnaires), use of antireflux medication, and complications. Results By five years, 63% (112/178) of patients randomised to surgery and 13% (24/179) of those randomised to medical management had received a fundoplication (plus 85% (222/261) and 3% (6/192) of those who expressed a preference for surgery and for medical management). Among responders at 5 years, 44% (56/127) of those randomised to surgery were taking antireflux medication versus 82% (98/119) of those randomised to medical management. Differences in the REFLUX score significantly favoured the randomised surgery group (mean difference 8.5 (95% CI 3.9 to 13.1), Preflux-related operations—most often revision of the wrap. Long term rates of dysphagia, flatulence, and inability to vomit were similar in the two randomised groups. Conclusions After five years, laparoscopic fundoplication continued to provide better relief of GORD symptoms than medical management. Adverse effects of surgery were uncommon and generally observed soon after surgery. A small proportion had re-operations. There was no evidence of long term adverse

    Lesogaberan (AZD3355) is a novel γ-aminobutyric acid B-type receptor agonist designed to treat gastro-oesophageal reflux disease (GERD) by inhibiting transient lower oesophageal sphincter relaxations. A randomised, double-blind, placebo-controlled, multi-centre phase IIb study was performed to assess the efficacy and safety of lesogaberan as an add-on to proton pump inhibitor (PPI) therapy in patients with GERD who are partially responsive to PPI therapy (ClinicalTrials.gov reference: NCT01005251). In total, 661 patients were randomised to receive 4 weeks of placebo or 60, 120, 180 or 240 mg of lesogaberan twice daily, in addition to ongoing PPI therapy. Symptoms were measured using the Reflux Symptom Questionnaire electronic Diary. Response to treatment was defined as having an average of ≥ 3 additional days per week of not more than mild GERD symptoms during treatment compared with baseline. In the primary analysis, 20.9%, 25.6%, 23.5% and 26.2% of patients responded to the 60, 120, 180 and 240 mg twice daily lesogaberan doses, respectively, and 17.9% responded to placebo. The response to the 240 mg twice daily dose was statistically significantly greater than the response to placebo using a one-sided test at the predefined significance level of p < 0.1. However, the absolute increases in the proportions of patients who responded to lesogaberan compared with placebo were low. Lesogaberan was generally well tolerated, although six patients receiving lesogaberan developed reversible elevated alanine transaminase levels. In patients with GERD symptoms partially responsive to PPI therapy, lesogaberan was only marginally superior to placebo in achieving an improvement in symptoms.

    Despite encouraging results from screening trials the efficacy of mammography in reducing mortality remains somewhat controversial. Five studies have been done in Sweden. This overview, reveals a 24% significant reduction of breast cancer mortality among those invited to mammography screening compared with those not invited. To avoid the potential risk of differential misclassification causes of death were assessed by an independent end-point committee after a blinded review of all fatal breast cancer cases. The mortality reduction was similar, irrespective of the end-point used for evaluation (breast cancer as underlying cause of death or breast cancer present at death). There was a consistent risk reduction associated with screening in all studies, although the point estimate of the relative risk for all ages varied non-significantly between 0.68 and 0.84. The cumulative breast cancer mortality by time since randomization was estimated at 1.3 per 1,000 within 6 years in the invited group compared with 1.6 in the control group. The corresponding figures after 9 years are 2.6 and 3.3 and after 12 years 3.9 and 5.1

    Objectives To investigate the effects of Helicobacter pylori infection and its eradication on heartburn and gastro-oesophageal reflux. Design Cross sectional study, followed by a randomised placebo controlled trial. Setting Seven general practices in Bristol, England. Participants 10 537 people, aged 20-59 years, with and without H pylori infection (determined by the 13C-urea breath test). Main outcome measures Prevalence of heartburn and gastro-oesophageal acid reflux at baseline and two years after treatment to eradicate H pylori infection. Results At baseline, H pylori infection was associated with increased prevalence of heartburn (odds ratio 1.14, 95% confidence interval 1.05 to 1.23) but not reflux (1.05, 0.97 to 1.14). In participants with H pylori infection, active treatment had no effect on the overall prevalence of heartburn (0.99, 0.88 to 1.12) or reflux (1.04, 0.91 to 1.19) and did not improve pre-existing symptoms of heartburn or reflux. Conclusions H pylori infection is associated with a slightly increased prevalence of heartburn but not reflux. Treatment to eradicate H pylori has no net benefit in patients with heartburn or gastro-oesophageal reflux. PMID:15126313

    Full Text Available Abstract Background Epidemiological studies suggest that smokeless tobacco in the form of Swedish snus has been used by many smokers in Scandinavia to quit smoking, but the efficacy of snus has so far not been evaluated in controlled clinical trials. Methods We conducted a randomized, double-blind, placebo-controlled, clinical trial aimed at assessing the efficacy of snus to help adult cigarette smokers in Serbia to substantially reduce, and, eventually, completely stop smoking. The study enrolled 319 healthy smokers aged 20-65 years at two occupational health centers in Belgrade, Serbia. Most of them (81% expressed an interest to quit rather than just reduce their smoking. Study products were used ad libitum throughout the 48-week study period. The main study objective during the first 24 weeks was smoking reduction. The primary end-point was defined as a biologically verified reduction of ≥ 50% in the average number of smoked cigarettes per day during week 21-24 compared to baseline. During week 25-48 participants were actively instructed to stop smoking completely. Outcome measures of biologically verified, complete smoking cessation included 1-week point prevalence rates at clinical visits after 12, 24, 36, and 48 weeks, as well as 4-, 12- and 24-week continued cessation rates at the week 36 and 48 visits. Results At the week 24 visit, the proportion of participants who achieved the protocol definition of a ≥ 50% smoking reduction was similar in the two treatment groups. However, the proportion that reported more extreme reductions (≥ 75% was statistically significantly higher in the snus group than in the placebo group (p Conclusions Swedish snus could promote smoking cessation among smokers in Serbia, that is, in a cultural setting without traditional use of oral, smokeless tobacco.

    A randomized controlled trial conducted in patients with gastroesophageal reflux disease compared optimized medical therapy using proton pump inhibitor (n = 52) with laparoscopic Nissen fundoplication (n = 52). Patients were monitored for 1 year. The primary end point was frequency of gastroesophageal reflux dis-ease symptoms. Surgical patients had improved symptoms, pH control, and overall quality of life health index after surgery at 1 year compared with the medical group. The overall gastroesophageal reflux disease symptom score at 1 year was unchanged in the medical patients, but improved in the surgical patients. Fourteen patients in the medical arm experienced symptom relapse requiring titration of the proton pump inhibitor dose, but 6 had satisfactory symptom remission. No surgical patients required additional treatment for symptom control. Patients controlled on long-term proton pump inhibitor therapy for chronic gastroesophageal reflux disease are excellent surgical candidates and should experience improved symptom control after surgery at 1 year.

    Purpose: The Swedish Rectal Cancer Trial (SRCT) demonstrated that a short-term regimen of high-dose fractionated preoperative radiotherapy (5 x 5 Gy) reduced the local recurrence rates and improved overall survival. This has had an impact on the primary treatment of rectal cancer. The current study investigated the cost-effectiveness of the new combined approach. Methods and Materials: After an 8-year follow-up, in-hospital and outpatient costs related to the treatment of rectal cancer and its complications were analyzed for 98 randomly allocated patients who participated in the SRCT from a single Swedish health care region. The costs were then related to the clinical data from the SRCT regarding complications, local and distant recurrences, and survival. Results: The total cost for a nonirradiated patient was US$30,080 compared with US$35,268 for an irradiated patient. The surgery-alone group had increased costs related to local recurrences, and the radiotherapy group had increased costs for irradiation and complications. With a survival benefit of 21 months (retrieved from the SRCT), the cost for a saved year was US$3654. Sensitivity analyses for different rates of local recurrences, the costs related to complications and less marked survival benefit showed that this figure could vary up to US$15,228. Conclusion: The cost for a life-year saved in these data was US$3654. This figure could reach US$15,228 in the most pessimistic setting of the sensitivity tests, a cost still comparable with other well-accepted medical interventions

    Despite promising evidence that laparoscopic fundoplication provides better short-term relief of gastro-oesophageal reflux disease (GORD) than continued medical management, uncertainty remains about whether benefits are sustained and outweigh risks. To evaluate the long-term clinical effectiveness, cost-effectiveness and safety of laparoscopic surgery among people with GORD requiring long-term medication and suitable for both surgical and medical management. Five-year follow-up of a randomised trial (with parallel non-randomised preference groups) comparing a laparoscopic surgery-based policy with a continued medical management policy. Cost-effectiveness was assessed alongside the trial using a NHS perspective for costs and expressing health outcomes in terms of quality-adjusted life-years (QALYs). Follow-up was by annual postal questionnaire and selective hospital case notes review; initial recruitment in 21 UK hospitals. Questionnaire responders among the 810 original participants. At entry, all had documented evidence of GORD and symptoms for > 12 months. Questionnaire response rates (years 1-5) were from 89.5% to 68.9%. Three hundred and fifty-seven participants were recruited to the randomised comparison (178 randomised to surgical management and 179 randomised to continued medical management) and 453 to the preference groups (261 surgical management and 192 medical management). The surgeon chose the type of fundoplication. Primary: disease-specific outcome measure (the REFLUX questionnaire); secondary: Short Form questionnaire-36 items (SF-36), European Quality of Life-5 Dimensions (EQ-5D), NHS resource use, reflux medication, complications. The randomised groups were well balanced. By 5 years, 63% in the randomised surgical group and 13% in the randomised medical management group had received a total or partial wrap fundoplication (85% and 3% in the preference groups), with few perioperative complications and no associated deaths.

    This paper deals with detection and quantification of gastroesophageal reflux. Gastroesophageal reflux (GER) generally refers to a symptom complex consisting of heartburn, regurgitation, and chest pain, the latter of which is often confused with pain of cardiac origin. Gastroesophageal reflux occurs when gastric or duodenal contents enter the esophagus. This phenomenon of symptomatic gastroesophageal reflux has been attributed to a variety of anatomic abnormalities, including loss of the acute cardioesophageal Angle of Hiss, widening of the diaphragmatic hiatus, loss of a normal gastric rosette formed by apposition of the gastric mucosal folds, disruption of the phrenoesophageal ligament, and conversion of the distal paraesophageal pressure from an intra-abdominal to an intrathoracic level. Lower esophageal sphincter (LES) dysfunction has been suggested as a major determinant of gastroesophageal competence. Quantitative scintigraphic studies of gastroesophageal reflux suggest that the LES pressure is the important determinant of gastroesophageal reflux, although some investigators have failed to confirm this role of the LES in gastroesophageal competence

    Many reflux patients remain symptomatic on a standard dose of proton pump inhibitor (PPI). Alginates decrease the number of reflux events by forming a raft on top of the stomach content and thus offer a supplemental mechanism of action to acid suppression. To assess the efficacy of an alginate (Gaviscon Advance, Reckitt Benckiser, Slough, UK) on reflux symptoms in patients with persistent symptoms despite once daily PPI. This was a multicentre, randomised, placebo-controlled, 7-day double-blind trial preceded by a 7-day run-in period. Reflux symptoms were assessed using the Heartburn Reflux Dyspepsia Questionnaire (HRDQ). Based on symptom score during run-in, eligible patients were randomised to Gaviscon Advance 10 mL four times a day or placebo in addition to a once daily PPI. The primary endpoint was change in HRDQ score post-treatment compared to baseline. One hundred and thirty-six patients were randomised. Change in HRDQ reflux score was significantly greater for Gaviscon Advance (mean: -5.0, s.d.: 4.7) than for placebo (mean: -3.5, s.d.: 5.5) with an LS mean difference of 1.6 [95% CI -3.1 to -0.1], P = 0.03. A decrease in the mean (s.d.) number of nights with symptoms was observed from 3.6 (2.8) to 3.0 (3.0) in the placebo group and from 3.9 (2.8) to 2.2 (2.7) for the Gaviscon Advance group. This reduction was significantly greater in the Gaviscon Advance group than in the placebo group [LS mean difference = -0.9, 95% CI (-1.6 to -0.2), P < 0.01]. In patients with residual reflux symptoms despite PPI treatment, adding an alginate offers additional decrease in the burden of reflux symptoms (EudraCT/IND Number: 2011-005486-21). © 2016 John Wiley & Sons Ltd.

    Full Text Available Background: Gastroesophageal reflux disease (GERD is one of the most common problems in neonates. The main clinical manifestations of neonatal GERD are frequent regurgitation or vomiting associated with irritability, crying, anorexia or feeding refusal, failure to thrive, arching of the back and sleep disturbance.Aims: As no study has compared metoclopramide plus ranitidine with metoclopramide plus omeprazole in the management of neonatal GERD resistant to conservative and monotherapy, this study was carried out.Study design: This study was a randomized clinical trial of term neonates with GERD resistant to conservative and monotherapy admitted to the neonatal ward of Bahrami Children Hospital during 2013-2015. Totally, 116 term neonates (mean age 10.53 ± 8.17 days; girls 50.9% were randomly assigned to a double blind trial with either oral omeprazole plus metoclopramide (group A or oral ranitidine plus metoclopramide (group B. The changes of the symptoms and signs were recorded after one week and one month.Results: There was no significant difference in demographic and baseline characteristics between the two groups. The response rate of “omeprazole plus metoclopramide” was significantly higher than “ranitidine plus metoclopramide” (93.74% ± 7.28% vs. 75.43% ± 23.24%, p = 0.028. All clinical manifestations recovered significantly in group A while the response rate of irritability and wheezing was not significant in group B (primary outcome. There were no side effects in either group after one week and one month of treatment (secondary outcome.Conclusions: The response rate was > 70% in each group, but it was significantly higher in group A (> 90%. Combination of each acid suppressant with metoclopramide led to higher response rate in comparison with monotherapy used before intervention.

    Full Text Available It is unclear whether the benefits that some patients derive from complementary and integrative medicine (CIM are related to the therapies recommended or to the consultation process as some CIM provider visits are more involved than conventional medical visits. Many patients with gastrointestinal conditions seek out CIM therapies, and prior work has demonstrated that the quality of the patient-provider interaction can improve health outcomes in irritable bowel syndrome, however, the impact of this interaction on gastroesophageal reflux disease (GERD is unknown. We aimed to assess the safety and feasibility of conducting a 2 x 2 factorial design study preliminarily exploring the impact of the patient-provider interaction, and the effect of an over-the-counter homeopathic product, Acidil, on symptoms and health-related quality of life in subjects with GERD.24 subjects with GERD-related symptoms were randomized in a 2 x 2 factorial design to receive 1 either a standard visit based on an empathic conventional primary care evaluation or an expanded visit with questions modeled after a CIM consultation and 2 either Acidil or placebo for two weeks. Subjects completed a daily GERD symptom diary and additional measures of symptom severity and health-related quality of life.There was no significant difference in GERD symptom severity between the Acidil and placebo groups from baseline to follow-up (p = 0.41, however, subjects who received the expanded visit were significantly more likely to report a 50% or greater improvement in symptom severity compared to subjects who received the standard visit (p = 0.01. Total consultation length, perceived empathy, and baseline beliefs in CIM were not associated with treatment outcomes.An expanded patient-provider visit resulted in greater GERD symptom improvement than a standard empathic medical visit. CIM consultations may have enhanced placebo effects, and further studies to assess the active components of this

    The aim of this study was to compare the therapeutic efficacy of alginate-based reflux suppressant and magnesium-aluminium antacid gel for treatment of heartburn in pregnancy. A double-blinded, randomized, controlled trial was conducted. One hundred pregnant women at less than 36 weeks gestation with heartburn at least twice per week were randomized to either alginate-based reflux suppressant or to magnesium-aluminium antacid gel. Details of heartburn were recorded before beginning the treatment and the second week of study. Primary outcome measure was the improvement of heartburn frequency after treatment and secondary outcome were the improvement of heartburn intensity, quality of life, maternal satisfaction, maternal side effects, pregnancy and neonatal outcomes. There was no difference between treatment and control groups in improvement of heartburn frequency (80% vs 88%, p = 0.275), 50% reduction of frequency of heartburn (56% vs 52%, p = 0.688), improvement of heartburn intensity (92% vs 92%, p = 1.000) and 50% reduction of heartburn intensity (68% vs 80% cases, p = 0.075). There were also no significant differences in quality of life, maternal satisfaction, maternal side effects, pregnancy and neonatal outcomes. Alginate-based reflux suppressant was not different from magnesium-aluminium antacid gel in the treatment of heartburn in pregnancy. PMID:28317885

    Full Text Available Objective. The purpose of this pilot study was to investigate and compare the effects of reflexology and Swedish massage therapy on physiologic stress, pain, and mood in older cancer survivors residing in nursing homes. Methods. An experimental, repeated-measures, crossover design study of 18 nursing home residents aged 75 or over and diagnosed with solid tumor in the past 5 years and following completion of cancer treatments. The intervention tested was 20 minutes of Swedish Massage Therapy to the lower extremities, versus 20 minute Reflexology, using highly specified protocols. Pre- and post-intervention levels of salivary cortisol, observed affect, and pain were compared in the Swedish Massage Therapy and Reflexology conditions. Results. Both Reflexology and Swedish Massage resulted in significant declines in salivary cortisol and pain and improvements in mood. Conclusions. Preliminary data suggest that studies of Swedish Massage Therapy and Reflexology are feasible in this population of cancer survivors typically excluded from trials. Both interventions were well tolerated and produced measurable improvements in outcomes. Further research is needed to explore the mechanisms underlying the potential benefits of these CAM modalities in this patient population.

    To investigate the clinical response of gastro-esophageal reflux disease (GERD) symptoms to exclusion diets based on food intolerance tests. A double blind, randomized, controlled pilot trial was performed in 38 GERD patients partially or completely non-responders to proton pump inhibitors (PPI) treatment. Fasting blood samples from each patients were obtained; leukocytotoxic test was performed by incubating the blood with a panel of 60 food items to be tested. The reaction of leukocytes (rounding, vacuolization, lack of movement, flattening, fragmentation or disintegration of cell wall) was then evaluated by optical microscopy and rated as follows: level 0 = negative, level 1 = slightly positive, level 2 = moderately positive, and level 3 = highly positive. A "true" diet excluding food items inducing moderate-severe reactions, and a "control" diet including them was developed for each patient. Then, twenty patients received the "true" diet and 18 the "control" diet; after one month (T1) symptoms severity was scored by the GERD impact scale (GIS). Hence, patients in the "control" group were switched to the "true" diet, and symptom severity was re-assessed after three months (T2). At baseline (T0) the mean GIS global score was 6.68 (range: 5-12) with no difference between "true" and control group (6.6 ± 1.19 vs 6.7 ± 1.7). All patients reacted moderately/severely to at least 1 food (range: 5-19), with a significantly greater number of food substances inducing reaction in controls compared with the "true" diet group (11.6 vs 7.0, P < 0.001). Food items more frequently involved were milk, lettuce, brewer's yeast, pork, coffee, rice, sole asparagus, and tuna, followed by eggs, tomato, grain, shrimps, and chemical yeast. At T1 both groups displayed a reduction of GIS score ("true" group 3.3 ± 1.7, -50%, P = 0.001; control group 4.9 ± 2.8, -26.9%, P = 0.02), although the GIS score was significantly lower in "true" vs "control" group (P = 0.04).

    Partial fundoplications provide similar reflux control with fewer post-fundoplication symptoms compared with Nissen fundoplication for gastro-oesophageal reflux disease (GORD). The best choice of procedure for partial fundoplication remains unclear. The aim of this study was to compare the outcome of two different types of partial fundoplication for GORD. A double-blind RCT was conducted between 2012 and 2015 in two hospitals specializing in antireflux surgery. Patients were randomized to undergo either a laparoscopic 270° posterior fundoplication (Toupet) or a laparoscopic 180° anterior fundoplication. The primary outcome was postoperative dysphagia at 12 months, measured by the Dakkak score. Subjective outcome was analysed at 1, 3, 6 and 12 months after surgery. Objective reflux control was assessed before and 6 months after surgery. Ninety-four patients were randomized to laparoscopic Toupet or laparoscopic 180° anterior fundoplication (47 in each group). At 12 months, 85 patients (90 per cent) were available for follow-up. Objective scores were available for 76 (81 per cent). Postoperative Dakkak dysphagia score at 12 months was similar in the two groups (mean 5·9 for Toupet versus 6·4 for anterior fundoplication; P = 0·773). Subjective outcome at 12 months demonstrated no significant differences in control of reflux or post-fundoplication symptoms. Overall satisfaction and willingness to undergo surgery did not differ between the groups. Postoperative endoscopy and 24-h pH monitoring showed no significant differences in mean oesophageal acid exposure time or recurrent pathological oesophageal acid exposure. Both types of partial fundoplication provided similar control of GORD at 12 months, with no difference in post-fundoplication symptoms.

    Full Text Available Background: In 4–10 % of patients with gastroesophageal reflux (GER some atypical symptoms are found (cough, hoarseness, globus pharyngeus, dyspnea which are characteristic for laryngopharyngeal reflux (LPR. The signs of LPR can be detected in more than 50 % of dysphonic patients. In the diagnostics of LPR, a meticulous history and a videoendoscopy of the larynx and pharynx are the most important procedures. The diagnosis of LPR can be confirmed by the 24-hour double probe pH monitoring and the treatment test with proton pump inhibitors. The best diagnostic results can be obtained with a combination of several diagnostic procedures.Conclusions: An otorhinolaryngologist can start a treatment test with proton pump inhibitors in a patient in whom a laryngopharyngeal reflux is suspected on the basis of history and laryngopharyngeal endoscopy. A successful treatment requires at least 12 weeks regimen with high doses 20 mg twice a day. In the case of alarm signs and unsuccessful treatment a gastroenterologic intervention is necessary.

    The Swedish Nuclear Power Inspectorate (SKI) and the US Department of Energy (DOE) sponsored work on a Remote Monitoring System (RMS) that was installed in August 1994 at the Barseback Works north of Malmo, Sweden. The RMS was designed to test the front end detection concept that would be used for unattended remote monitoring activities. Front end detection reduces the number of video images recorded and provides additional sensor verification of facility operations. The function of any safeguards Containment and Surveillance (C/S) system is to collect information which primarily is images that verify the operations at a nuclear facility. Barseback is ideal to test the concept of front end detection since most activities of safeguards interest is movement of spent fuel which occurs once a year. The RMS at Barseback uses a network of nodes to collect data from microwave motion detectors placed to detect the entrance and exit of spent fuel casks through a hatch. A video system using digital compression collects digital images and stores them on a hard drive and a digital optical disk. Data and images from the storage area are remotely monitored via telephone from Stockholm, Sweden and Albuquerque, NM, USA. These remote monitoring stations operated by SKI and SNL respectively, can retrieve data and images from the RMS computer at the Barseback Facility. The data and images are encrypted before transmission. This paper presents details of the RMS and test results of this approach to front end detection of safeguard activities

    1985-01-01

    Vesicoureteral reflux (VUR) is mainly a primary phenomenon due to incompetence of the ureterovesical junction, mostly affecting a pediatric population. During micturition cystourethrography (MCU) reflux into the kidney - intrarenal reflux (IRR) - is occasionally seen. In areas with IRR the kidney surface may subsequently be depressed and the papillae retracted (reflux nephropathy (RN)). VUR may lead to hypertension and/or end-stage renal failure. Most commonly, VUR is discovered during evaluation for urinary tract infection, but it may also be present in patients with hypertension, toxemia of pregnancy, chronic renal failure and proteinuria, and it may be found in siblings of patients with VUR. For the time being VUR is demonstrated at radiographic MCU, whereas RN is diagnosed by demonstration of focal scars and of abnormal parenchymal thickness at urography. In children with VUR and no abnormalities of calyces or parenchymal defects standardized measurement of the parenchymal thickness at three sites may identify kidneys which are likely to develop focal scars. Quantitation of focal scarring should be performed in connection with a measure of the overall kidney size. The occurrence of IRR is dependent of the papillary morphology, intrapelvic pressure and urine flow. There may be an important relationship between renal ischemia and IRR in producing a 'vicious circle of deleterious effects' which, combined with parenchymal extravasation, may lead to RN. Treatment of VUR includes medical and surgical management. Since renal scarring may occur in infancy, prevention should focus on infants and young children. Infants and young children with severe VUR may have normal urograms. Therefore a MCU should also be performed, preferably with the recommended standardized technique. (orig.)

    2015-08-01

    Gastroesophageal reflux (GER) can cause respiratory symptoms and may trigger, drive and/or worsen airway disorders, interstitial lung diseases and lung allograft dysfunction. Whether lifestyle changes and acid suppression alone can counter and prevent the adverse effects of GER on the respiratory tract remains unclear. Recent data suggest that antireflux surgery may be more effective in preventing lung disease progression in patients with idiopathic pulmonary fibrosis or lung transplant recipients who have evidence of allograft dysfunction associated with the presence of excessive GER. Additional research and clinical trials are needed to determine the role of GER in various lung disorders and identify which interventions are most efficacious in preventing the respiratory consequences of gastroesophageal reflux disease. In addition, measuring biomarkers that indicate that gastric refluxate has been aspirated into the lower respiratory tract (e.g., pepsin and bile acid concentrations in bronchoalveolar lavage fluid) may prove helpful in both diagnosis and therapeutic decision making.

    Pantoprazole magnesium (pantoprazole-Mg) may display extended inhibition of the proton pump with the potential for improved clinical efficacy in gastro-oesophageal reflux disease (GERD). To compare the efficacy of pantoprazole-Mg and esomeprazole in GERD. Gastro-oesophageal reflux disease (Los Angeles grades A-D) patients were randomised to 4 weeks of treatment with pantoprazole-Mg (n = 290) or esomeprazole (n = 288), both 40 mg once daily, in this multicentre (14 Brazilian sites in 9 cities), double-blind study, with an additional 4 weeks' treatment in nonresponding patients. Severity of oesophagitis (at endoscopy) and GERD-related symptoms (ReQuest-GI) were assessed. The primary end point was the proportion of patients in complete remission (ReQuest-GI score <1.73 plus endoscopic healing) at week 4. Complete remission occurred in 61% of patients in each treatment group at 4 weeks (primary endpoint) and in 81% and 79% of patients in the pantoprazole-Mg and esomeprazole groups at 8 weeks, with no significant differences. Mucosal healing rates were high and not significantly different. At 8 weeks, symptom relief with pantoprazole-Mg was significantly greater than that with esomeprazole (91.6% vs. 86.0%, P = 0.0370) because of continued improvement in symptoms with pantoprazole-Mg from week 4 to week 8 (P = 0.0206). Pantoprazole-Mg 40 mg was at least as effective as esomeprazole 40 mg for complete remission and the mucosal healing rate was high. Symptom relief with pantoprazole-Mg continued to improve from 4 to 8 weeks and was greater than that with esomeprazole at week 8, suggesting an extended period of treatment effect (ClinicalTrials.gov identifier: NCT01132638). © 2013 John Wiley & Sons Ltd.

    Bariatric surgery is the only treatment option that achieves sustained weight loss in obese patients and that also has positive effects on obesity-related comorbidities. Laparoscopic sleeve gastrectomy (LSG) seems to achieve equal weight loss as laparoscopic Roux-en-Y gastric bypass (LRYGB), but there is still much debate about the quality of life (QOL) after LSG, mainly concerning the association with gastroesophageal reflux. Our hypothesis is that QOL after LSG is comparable with QOL after LRYGB. Between February 2013 and February 2014, 150 patients were randomized to undergo either LSG or LRYGB in our clinic. Differences in QOL were compared between groups by using multiple QOL questionnaires at follow-up moments preoperatively and 2 and 12 months after surgery. After 12 months of follow-up, 128 patients had returned the questionnaires. Most QOL questionnaires showed significant improvement in scores between the preoperative moment and after 12 months of follow-up. The Gastroesophageal Reflux Disease Questionnaire (GerdQ) score deteriorated in the LSG group after 2 months, but recovered again after 12 months. After 2 months of follow-up, the mean GerdQ score was 6.95 ± 2.14 in the LSG group versus 5.50 ± 1.49 in the LRYGB group (p < 0.001). After 1 year, the mean GerdQ score was 6.63 ± 2.26 in the LSG group and 5.60 ± 1.07 in the LRYGB group (p = 0.001). This randomized controlled trial shows that patients who underwent LSG have significantly higher GerdQ scores at both 2 and 12 months postoperatively than patients who underwent LRYGB, whereas overall QOL did not differ significantly.

  20. A Meta-Analysis of Randomized Controlled Trials to Compare Long-Term Outcomes of Nissen and Toupet Fundoplication for Gastroesophageal Reflux Disease.

    Full Text Available In recent years, several studies with large sample sizes and recent follow-up data have been published comparing outcomes between laparoscopic Nissen fundoplication and laparoscopic Toupet fundoplication. It is now timely to be re-evaluated and synthesized long-term efficacy and adverse events of both total and partial posterior fundoplication.Electronic searches for RCTs comparing the outcome after laparoscopic Nissen fundoplication and laparoscopic Toupet fundoplication were performed in the databases of MEDLINE, EMBASE, and the Cochrane Center Register of Controlled Trials. The data of evaluation in positive and adverse results of laparoscopic Nissen fundoplication and laparoscopic Nissen fundoplication were extracted and compared using meta-analysis.13 RCTs were ultimately identified involving 814 (52.05% and 750 (47.95% patients who underwent laparoscopic Nissen fundoplication and laparoscopic Toupet fundoplication, respectively. The operative time, perioperative complications, postoperative satisfaction, recurrence, and the rates of medication adoption or re-operation due to recurrence were not significantly different between two groups. The two types of fundoplication both reinforced the anti-reflux barrier and elevated the lower esophageal sphincter pressure. However, rates of adverse results involving dysphasia, gas-bloat syndrome, inability to belch and re-operation due to severe dysphasia were significantly higher after LNF. In the subgroup analysis of wrap length≤2 cm, laparoscopic Nissen fundoplication was associated with a significantly higher incidence of postoperative dysphagia. However, in the subgroup wrap length>2 cm, the difference was not statistically significant.Laparoscopic Toupet fundoplication might be the better surgery approach for gastroesophageal reflux disease with a lower rate of postoperative adverse results and equal effectiveness as Laparoscopic Nissen fundoplication.

    Nighttime heartburn, common among patients with gastro-oesophageal reflux disease (GERD), is associated with substantial clinical effects. GERD-related sleep disturbances are underappreciated and undertreated. To evaluate the efficacy of esomeprazole on GERD-related nighttime heartburn and associated sleep disturbances. In this multicentre, randomized, double-blind, placebo-controlled study, patients with moderate-to-severe nighttime heartburn and GERD-related sleep disturbances (endoscopies not required) received esomeprazole 20 mg or placebo each morning for 4 weeks. Heartburn symptoms and GERD-related sleep disturbances were evaluated using the validated Pittsburgh Sleep Quality Index and validated Work Productivity and Activity Impairment Questionnaire. The analysis included 262 patients (esomeprazole, n = 137; placebo, n = 125). Significantly more patients receiving esomeprazole achieved nighttime heartburn relief (primary end point) than those receiving placebo (34.3% vs. 10.4%; P heartburn and GERD-related sleep disturbances, improving heartburn symptoms, sleep quality, work productivity and functionality.

  2. Endoscopic and laparoscopic treatment of gastroesophageal reflux.

    2010-04-01

    Gastroesophageal reflux is extremely common in Western countries. For selected patients, there is an established role for the surgical treatment of reflux, and possibly an emerging role for endoscopic antireflux procedures. Randomized trials have compared medical versus surgical management, laparoscopic versus open surgery and partial versus total fundoplications. However, the evidence base for endoscopic procedures is limited to some small sham-controlled studies, and cohort studies with short-term follow-up. Laparoscopic fundoplication has been shown to be an effective antireflux operation. It facilitates quicker convalescence and is associated with fewer complications, but has a similar longer term outcome compared with open antireflux surgery. In most randomized trials, antireflux surgery achieves at least as good control of reflux as medical therapy, and these studies support a wider application of surgery for the treatment of moderate-to-severe reflux. Laparoscopic partial fundoplication is an effective surgical procedure with fewer side effects, and it may achieve high rates of patient satisfaction at late follow-up. Many of the early endoscopic antireflux procedures have failed to achieve effective reflux control, and they have been withdrawn from the market. Newer procedures have the potential to fashion a surgical fundoplication. However, at present there is insufficient evidence to establish the safety and efficacy of endoscopic procedures for the treatment of gastroesophageal reflux, and no endoscopic procedure has achieved equivalent reflux control to that achieved by surgical fundoplication.

    Only a few reports focused on esophageal motility in patients with proton pump inhibitor (PPI)-refractory nonerosive reflux disease (NERD) and there has been no established strategy for treatment. To clarify the characteristics of esophageal motility in patients with PPI-refractory NERD, we evaluated esophageal function using combined multichannel intraluminal impedance and esophageal manometry (MII-EM). In addition, we evaluated the efficacy of rikkunshito (RKT), which is a gastrointestinal prokinetic agent. Thirty patients with NERD were enrolled and underwent MII-EM. After 8 weeks of RKT (7.5 g/d) treatment, MII-EM was repeated on patients with PPI-refractory NERD. Symptoms were assessed by the Gastrointestinal Symptom Rating Scale. In patients with PPI-refractory NERD, measures of complete bolus transit, peristaltic contractions, and residual pressure of the lower esophageal sphincter during swallowing deviated from the standard values and esophageal clearance was found to be deteriorated. RKT significantly improved the peristaltic contractions ( P esophageal sphincter ( P disorders of esophageal and lower esophageal sphincter motility that were improved by RKT. Further studies examining esophageal motor activity of RKT in PPI-refractory NERD are required.

    The alginate-antacid, Gaviscon Double Action (Gaviscon DA; Reckitt Benckiser, Slough, UK) suppresses reflux after meals by creating a gel-like barrier that caps and displaces the acid pocket distal to the oesophago-gastric junction. The effect of Gaviscon DA on reflux and dyspepsia symptoms has not yet been demonstrated with a modern trial design. A pilot study to assess the efficacy and safety of Gaviscon DA compared with matched placebo for decreasing upper gastrointestinal symptoms in symptomatic gastro-oesophageal reflux disease (GERD) patients. A randomised, double-blind, parallel group study was performed in 110 patients with symptoms of GERD. Patients received Gaviscon DA or placebo tablets for 7 consecutive days. The primary endpoint compared the change in overall Reflux Disease Questionnaire (RDQ) symptom score (combined heartburn/regurgitation/dyspepsia). Secondary endpoints assessed individual dimensions, GERD dimension (heartburn and regurgitation) and overall treatment evaluation (OTE). There was a greater decrease in overall RDQ symptom score in the Gaviscon DA group compared with the placebo group (Least Squares Mean difference -0.55; P = 0.0033), and for each of the dimensions independently. Patients in the Gaviscon DA group evaluated their overall treatment response higher than patients in the placebo group [mean (standard deviation) OTE 4.1 (2.44) vs. 1.9 (3.34); P = 0.0005]. No differences in the incidence of adverse events were observed between treatment groups. Gaviscon DA decreases reflux and dyspeptic symptoms in GERD patients compared with matched placebo and has a favourable benefit-risk balance. Larger scale clinical investigations of medications targeting the acid pocket are warranted. (EudraCT, 2012-002188-84). © 2014 John Wiley & Sons Ltd.

    A randomized controlled trial (RCT) investigated patients with gastroesophageal reflux disease (GERD) who were stable and symptomatically controlled with long-term medical therapy to compare ongoing optimized medical therapy with laparoscopic Nissen fundoplication (LNF). Of the 180 patients eligible for randomization, 104 gave informed consent, and 3 withdrew from the study immediately after randomization. The patients randomized to medical therapy received optimized treatment with proton pump inhibitors (PPIs) using a standardized management protocol based on best evidence and published guidelines. The surgical patients underwent LNF by one of four surgeons using a previously published technique. The patients underwent symptom evaluation using the GERD symptom scale (GERSS) and the global visual analog scale (VAS) for overall symptom control. They had 24-h esophageal pH monitoring at baseline and after 3 years. The medical patients were evaluated receiving PPI, and the surgical patients were evaluated not receiving PPI. For the 3-year follow-up assessment, 93 patients were available. At 3 years, surgery was associated with more heartburn-free days, showing a mean difference of -1.35 days per week (p = 0.0077) and a lower VAS score (p = 0.0093) than medical management. Surgical patients reported improved quality of life on the general health subscore of the Medical Outcomes Survey Short Form 36 (SF-36) at 3 years, with a mean difference of -12.19 (p = 0.0124). The groups did not differ significantly in terms of GERSS or acid exposure on 24-h esophageal pH monitoring at 3 years. There were six treatment failures (11.8%) in the surgical group and eight treatment failures (16%) in the medical group by 3 years. For patients whose GERD symptoms are stable and controlled with PPI, continuing medical therapy and laparoscopic antireflux surgery are equally effective, although surgery may result in better symptom control and quality of life.

    Very few randomized controlled trials (RCTs) have compared laparoscopic Nissen fundoplication (LNF) to proton pump inhibitors (PPI) medical management for patients with chronic gastroesophageal reflux disease (GERD). Larger RCTs have been relatively short in duration, and have reported mixed results regarding symptom control and effect on quality of life (QOL). Economic evaluations have reported conflicting results. To determine the incremental cost-utility of LNF versus PPI for treating patients with chronic and controlled GERD over 3 years from the societal perspective. Economic evaluation was conducted alongside a RCT that enrolled 104 patients from October 2000 to September 2004. Primary study outcome was GERD symptoms (secondary outcomes included QOL and cost-utility). Resource utilization and QOL data collected at regular follow-up intervals determined incremental cost/QALY gained. Stochastic uncertainty was assessed using bootstrapping and methodologic assumptions were assessed using sensitivity analysis. No statistically significant differences in GERD symptom scores, but LNF did result in fewer heartburn days and improved QOL. Costs were higher for LNF patients by $3205/patient over 3 years but QOL was also higher as measured by either QOL instrument. Based on total costs, incremental cost-utility of LNF was $29,404/QALY gained using the Health Utility Index 3. Cost-utility results were sensitive to the utility instrument used ($29,404/QALY for Health Utility Index 3, $31,117/QALY for the Short Form 6D, and $76,310/QALY for EuroQol 5D) and if current lower prices for PPIs were used in the analysis. Results varied depending on resource use/costs included in the analysis, the QOL instrument used, and the cost of PPIs; however, LNF was generally found to be a cost-effective treatment for patients with symptomatic controlled GERD requiring long-term management.

    There is a paucity of large-scale studies evaluating the clinical benefit of the Gaviscon Double Action (DA) alginate-antacid formulation for treating gastroesophageal reflux disease (GERD) symptoms. Randomised double-blind placebo-controlled parallel-group study to evaluate efficacy and safety of Gaviscon DA in reducing heartburn, regurgitation and dyspepsia symptoms in individuals with mild-to-moderate GERD in China. Participants with symptomatic GERD (n = 1107) were randomised to receive Gaviscon DA or placebo (two tablets four times daily) for seven consecutive days. The primary endpoint compared the change in Reflux Disease Questionnaire (RDQ) score for the GERD (heartburn + regurgitation) dimension between Gaviscon DA and placebo. Secondary endpoints compared the change in RDQ scores for individual heartburn, regurgitation and dyspepsia dimensions, overall treatment evaluation (OTE) scores and incidence of adverse events (AEs). Mean RDQ GERD scores: 2.51 for Gaviscon DA and 2.50 for placebo at baseline; 1.25 for Gaviscon DA and 1.46 for placebo post treatment. Gaviscon DA was statistically superior to placebo in reducing GERD and dyspepsia RDQ scores [least-squares mean (LSM) difference: GERD -0.21, P GERD symptoms was observed both in those with non-erosive and those with erosive reflux disease (LSM difference -0.14 [P = 0.038] and -0.29 [P GERD.

    Full Text Available Vesicoureteral reflux (VUR management must be tailored based on the risk for further infections and renal scarring, gender, likelihood of spontaneous resolution, and parental preferences. Because we now understand that sterile VUR is benign and most reflux spontaneously resolves over time, the initial approach in majority of children is non-surgical with continuous antibiotic prophylaxis (CAP and correction of bladder and bowel dysfunction. Despite increasing utilization of CAP over the past four decades, the efficacy of antibiotic prophylaxis has been questioned due to conflicting results of studies plagued with design flaws and inadequate subject sample size. The Randomized Intervention for Children with Vesicoureteral Reflux (RIVUR trial, which was designed to address many of the limitations from previous studies, provided much needed answers. In this review, we sought to describe the controversy surrounding VUR management, highlight the results of RIVUR trial, and discuss how the RIVUR findings impact our understanding of CAP in the management of VUR.

    This study investigated the effectiveness of diaphragm biofeedback training (DBT) for patients with gastroesophageal reflux disease (GERD). A total of 40 patients with GERD treated at the Peking Union Medical College Hospital between September 2004 and July 2006 were randomized to receive DBT and rabeprazole proton pump inhibitor (PPI) or rabeprazole alone. The DBT + rabeprazole group received DBT during the 8-week initial treatment; the rabeprazole group did not. During the 6-month follow up, all patients took acid suppression according to their reflux symptoms, and the patients in the DBT + rabeprazole group were required to continue DBT. The primary outcome (used for power analysis) was the amount of acid suppression used at 6 months. Secondary outcomes were reflux symptoms, health-related quality of life (HRQL), and esophageal motility differences after the 8-week treatment compared with baseline. Acid suppression usage significantly decreased in the DBT + rabeprazole group compared with the rabeprazole group at 6 months (P reflux symptoms and GERD-HRQL were significantly improved in both groups (P gastroesophageal junction pressure (GEJP) significantly increased in the DBT + rabeprazole group (P reflux barrier, providing a non-pharmacological maintenance therapy and reducing medical costs for patients with GERD. © 2015 International Society for Diseases of the Esophagus.

    Ability to predict freedom from heartburn relapse during maintenance therapy for healed reflux oesophagitis may facilitate optimal treatment choices for individual patients. To determine factors predicting freedom from heartburn relapse during maintenance proton pump inhibitor therapy in patients with healed reflux oesophagitis. This post-hoc analysis used data from the maintenance phase of the EXPO study (AstraZeneca study code: SH-NEG-0008); 2766 patients with healed reflux oesophagitis and resolved heartburn received once-daily esomeprazole 20 mg or pantoprazole 20 mg for 6 months. Multiple logistic regression analysis determined factors associated with freedom from heartburn relapse. Heartburn relapse rates were lower with esomeprazole than pantoprazole in all subgroups analysed. Esomeprazole treatment was the factor most strongly associated with freedom from heartburn relapse (odds ratio 2.08; P heartburn relapse were Helicobacter pylori infection, greater age, non-obesity, absence of epigastric pain at baseline, pre-treatment nonsevere heartburn and GERD symptom duration heartburn relapse during maintenance proton pump inhibitor therapy for healed reflux oesophagitis, the strongest being choice of proton pump inhibitor. These findings outline the importance of optimizing acid control and identifying predictors of relapse for effective long-term symptom management in reflux oesophagitis patients.

    Objective: To evaluate the efficiency of percutaneously placed bioprosthetic bicuspid venous valve (BVV) in the treatment of deep vein insufficiency in animal experiments and clinical trials. Methods: BVV was made of two pieces of lyophilized porcine small intestinal submucosa(SIS) which were attached to a stent frame. Three kinds of BVVs (BVV1, BVV2, BVV3) was developed using different kinds of stent frames and different methods of attachment. BVV1, BVV2 and BVV3 were percutaneously placed into ovine's jugular veins acrossed the nature valves. Ascending and descending angiography were performed before and after' BVVs placement. The patency of veins and the function of valves was evaluated during 5 weeks to 6 months follow-up. In clinical trial, BVV1 and BVV3 were percutaneously placed into 3 and 15 patients with chronic venous insufficiency (CVI) respectively. The patency of veins and the function of valves was also evaluated during 1 to 3 years' follow-up. Results: In animal experiment, BVV1, BVV2, and BVV3 were placed to 24, 26 and 12 ovine's jugular veins respectively. During 5 weeks to 6 months follow- up period, 22 (88.0%), 24(92.3%) and 12 of the BVVs exhibited good function. Endothelium of both surfaces of SIS leaflets was complete in approximately 3 months. SIS was gradually reabsorbed and replaced by the host's own cells. Three BVV1 were placed into 3 patients with CVI. At the third years follow-up, symptoms relieved in 2 cases and no change of clinical symptoms was found in 1 patient. BVV3 were percutaneously placed into 15 patients with advanced symptomatic CVI. At one month and 3 months' follow- up after BVV3 placement, all BVV3 functioned well. However, BVV3 were flexible and functioned well in only 4 cases at 1 year' s follow-up. Intravascular ultrasound revealed thickened rigid cusps with valve leakage of different levels and no symptom resolved in 11 cases. Conclusions: Percutaneous implantation of bioprosthetic BVV is a promising method in the

  20. Gastro-oesophageal reflux. Part 1: smoking and alcohol reduction.

    Science.gov (United States)

    Al Talalwah, Narmeen; Woodward, Sue

    Gastro-oesophageal reflux disease (GORD) is defined as an abnormal reflux of the stomach contents into the oesophagus, which provokes symptoms and impairs the quality of life. GORD has a high prevalence and incurs costs to the healthcare system. This is the first paper in a series of three exploring the conservative, medical and surgical treatment of GORD. This first paper presents a review of the effect of smoking and alcohol on reflux symptoms and the impact of smoking and alcohol reduction on symptoms of GORD. A search for English language studies on adults was conducted using three databases, MEDLINE, Embase and the Cochrane Central Register of Controlled Trials (CENTRAL). Eleven relevant studies were included in the review. The effect of alcohol on the stimulation of reflux has been debated over the years in different studies. Some studies state that alcohol consumption induces reflux and moderate amounts exacerbate nocturnal gastro-oesophageal heartburn reflux. However, other studies have found no association between alcohol consumption and reflux. Most reflux occurs during smoking because nicotine causes the lower oesophageal sphincter to relax, which increases the risk of reflux. Similarly, the number of cigarettes smoked is associated with the risk of reflux. Nurses need to be aware of the effect of smoking and alcohol on reflux to provide evidence-based advice to empower patients to change their lifestyle, which results in increased therapeutic compliance and a better clinical status. There is no evidence that reducing alcohol consumption decreases symptoms and only limited evidence on the effectiveness of smoking cessation. Further research into the effectiveness of these lifestyle modifications is therefore required.

    Motivational interviewing (MI) is a client-centred, directive counselling style for helping people to explore and resolve ambivalence about behaviour change and shown to decrease drug and alcohol use. A five-session semi-structured MI intervention [Beteende, Samtal, Förändring (BSF; Behaviour, Counselling, Change)] was implemented in Swedish prisons. To examine whether, in a real-life implementation of semi-structured MI, staff receiving ongoing MI training, based on audio-recorded feedback in peer groups (BSF+), possess greater MI skill compared with staff receiving workshop-only MI training (BSF), and staff conducting usual prison planning interviews (UPI). Prisoners were randomised to one of the three interventions. The fi rst sessions between staff and prisoner with complete data were assessed with the Motivational Interviewing Treatment Integrity Code 3.0. Content analysis of 45 staff: prisoner sessions revealed that counsellors in the BSF+ group were significantly more competent in MI than those in the UPI group, but there was no difference in MI competency between the BSF and UPI groups. Overall, staff were rated as not having achieved beginning proficiency. Our findings suggest that staff delivering motivational interviewing programmes for substance-misusing prisoners in Sweden are not being given sufficient training for the task. Previous literature has suggested that staff need more than a basic 3- to 5-day workshop training, but our findings suggest that they may need longer-term continuing supervision and support than previously recognised.

    2015-08-01

    The prevalence of gastroesophageal reflux disease (GERD) in South Korea has increased over the past 10 years. Patients with erosive reflux disease (ERD) shows better response to proton pump inhibitors (PPIs) than those with non-erosive reflux disease (NERD). NERD is a heterogeneous condition, showing pathological gastroesophageal reflux or esophageal hypersensitivity to reflux contents. NERD patients with pathological gastroesophageal reflux or hypersensitivity to acid may respond to PPIs. However, many patients with esophageal hypersensitivity to nonacid or functional heartburn do not respond to PPIs. Therefore, careful history and investigations are required when managing patients with refractory GERD who show poor response to conventional dose PPIs. Combined pH-impedance studies and a PPI diagnostic trial are recommended to reveal underlying mechanisms of refractory symptoms. For those with ongoing reflux-related symptoms, split dose administration, change to long-acting PPIs or PPIs less influenced by CYP2C19 genotypes, increasing dose of PPIs, and the addition of alginate preparations, prokinetics, selective serotonin reuptake inhibitors, or tricyclic antidepressants can be considered. Pain modulators, selective serotonin reuptake inhibitors, or tricyclic antidepressants are more likely to be effective for those with reflux-unrelated symptoms. Surgery or endoscopic per oral fundoplication may be effective in selected patients.

    Expression of WRAP53 protein has oncogenic properties and it is up regulated in several types of tumors. We examined expression of WRAP53 protein in rectal cancers and analyzed its relationship to the response to preoperative radiotherapy and patient survival. The WRAP53 protein was examined by immunohistochemistry in normal mucosa, primary tumors and lymph node metastases from 143 rectal cancer patients participated in a Swedish clinical trial of preoperative radiotherapy. Frequency of WRAP53 protein expression was increased in primary rectal cancer compared to the normal mucosa (p < 0.05). In non-radiotherapy group positive WRAP53 in primary tumors (p = 0.03, RR, 3.73, 95% CI, 1.13-11.89) or metastases (p = 0.01, RR, 4.11, 95% CI, 1.25-13.14), was associated with poor prognosis independently of stages and differentiations. In radiotherapy group, positive WRAP53 in the metastasis correlated with better survival (p = 0.04). An interaction analysis showed that the correlations of WRAP53 with the prognostic significance with and without radiotherapy in the metastasis differed (p = 0.01). In the radiotherapy group, expression of WRAP53 in metastases gave a better outcome (p = 0.02, RR, 0.32, 95% CI, 0.13-0.84), and an interaction analysis showed significance between the two groups (p = 0.01). WRAP53 may be a new biomarker used to predict prognosis and to select suitable patients for preoperative radiotherapy

None of the subjects had gout at baseline. An endpoint on gout incidence was created based on information on gout diagnosis and use of gout medications through national registers and questionnaires. Median follow-up for the incidence of gout was about 19 years for both groups. Moreover, the incidence of hyperuricaemia over up to 20 years was examined in a subgroup of participants having baseline uric acid levels gout compared with usual care (adjusted HR 0.60, 95% CI 0.48 to 0.75, pgout event was 32 (95% CI 22 to 59). The effect of bariatric surgery on gout incidence was not influenced by baseline risk factors, including body mass index. During follow-up, the surgery group had a lower incidence of hyperuricaemia (adjusted HR 0.47, 95% CI 0.39 to 0.58, pgout and hyperuricaemia in obese subjects. NCT01479452; Results.

    The origin and significance of cardiac mucosa at the gastro-oesophageal junction are controversial. In the prospective Central European multicentre histoGERD trial, we aimed to assess the prevalence of cardiac mucosa, characterized by the presence of glands composed of mucous cells without parietal cells, and to relate its presence to features related to gastro-oesophageal reflux disease (GORD). One thousand and seventy-one individuals (576 females and 495 males; median age 53 years) were available for analysis. Overall, in biopsy specimens systematically taken from above and below the gastro-oesophageal junction, cardiac mucosa was observed in 713 (66.6%) individuals. Its presence was associated with patients' symptoms and/or complaints (P = 0.0025), histological changes of the squamous epithelium (P gastro-oesophageal junction. Its association with reflux symptoms, histological changes indicating GORD and the endoscopic diagnosis of oesophagitis suggests that injury and repair related to GORD contribute to its development and/or expansion. © 2014 John Wiley & Sons Ltd.

    Laparoscopic Nissen fundoplication (LNF) is the most common surgical procedure for the surgical management of gastro-esophageal reflux disease (GERD). Laparoscopic Toupet fundoplication (LTF) has been reported to have a lower prevalence of postoperative complications yet still obtain a similar level of reflux control. We conducted a meta-analysis to confirm the value of LNF and LTF. PubMed, Medline, Embase, Cochrane Library and Springerlink were searched for randomized controlled trials (RCTs) comparing LNF and LTF. Data regarding the benefits and adverse results of two techniques were extracted and compared using a meta-analysis. Eight eligible RCTs comparing LNF (n = 625) and LTF (n = 567) were identified. There were no significant differences between LNF and LTF with regard to hospitalization duration, perioperative complications, patient satisfaction, postoperative heartburn, regurgitation, postoperative DeMeester scores, or esophagites. A shorter operative time and higher postoperative lower esophageal sphincter pressure were associated with LNF. Prevalence of postoperative dysphagia, gas-bloating, inability to belch, dilatation for dysphagia and reoperation were higher after LNF, but subgroup analyses showed that differences with respect to dysphagia between LNF and LTF disappeared over time. Subgroup analyses did not support "tailored therapy" according to preoperative esophageal motility. LNF and LTF have equivalently good control of GERD and result in a similar prevalence of patient satisfaction. Based on current evidence, it is not rational or advisable to abandon LNF when choosing a surgical procedure for GERD.

    Gastroesophageal reflux disease is a chronic condition with a high prevalence in western countries. Transient lower esophageal sphincter relaxation episodes and a decreased lower esophageal sphincter pressure are the main mechanisms involved. Currently used drugs are efficient on reflux symptoms, but only as long as they are administered, because they do not modify the reflux barrier. Certain nutrients or foods are generally considered to increase the frequency of gastroesophageal reflux symptoms, therefore physicians recommend changes in diet and some patients avoid bothering foods. This review summarizes current knowledge regarding food and gastroesophageal reflux. For example, fat intake increases the perception of reflux symptoms. Regular coffee and chocolate induce gastroesophageal reflux and increase the lower esophageal exposure to acid. Spicy foods might induce heartburn, but the exact mechanism is not known. Beer and wine induce gastroesophageal reflux, mainly in the first hour after intake. For other foods, like fried food or carbonated beverages data on gastroesophageal reflux is scarce. Similarly, there is few data about the type of diet and gastroesophageal reflux. Mediterranean diet and a very low carbohydrate diet protect against reflux. Regarding diet-related practices, consistent data showed that a "short-meal-to-sleep interval" favors reflux episodes, therefore some authors recommend that dinner should be at least four hours before bedtime. All these recommendations should consider patient's weight, because several meta-analysis showed a positive association between increased body mass index and gastroesophageal reflux disease.

    2016-01-01

    Background Attendance in the cervical cancer screening programme is one of the most important factors to lower the risk of contracting the disease. Attendance rates are often low in areas with low socioeconomic status. Charging a fee for screening might possibly decrease attendance in this population. Screening programme coverage is low in low socio-economic status areas in Gothenburg, Sweden, but has increased slightly after multiple interventions in recent years. For many years, women in the region have paid a fee for screening. We studied the effect of abolishing this fee in a trial emanating from the regular cervical cancer screening programme. Method Individually randomised controlled trial. All 3 124 women in three low-resource areas in Gothenburg, due for screening during the study period, were randomised to receive an offer of a free test or the standard invitation stating the regular fee of 100 SEK (≈11 €). The study was conducted during the first six months of 2013. Attendance was defined as a registered Pap smear within 90 days from the date the invitation was sent out. Results Attendance did not differ significantly between women who were charged and those offered free screening (RR 0.93; CI 0.85–1.02). No differences were found within the districts or as an effect of age, attendance after the most recent previous invitation or previous experience of smear taking. Conclusion Abolishment of a modest screening fee in socially disadvantaged urban districts with low coverage, after previous multiple systematic interventions, does not increase attendance in the short term. Other interventions might be more important for increasing attendance in low socio-economic status areas. Trial Registration ClinicalTrials.gov NCT02378324 PMID:26986848

    Management of gastroesophageal reflux disease (GERD) commonly starts with an empiric trial of proton pump inhibitor (PPI) therapy and complementary lifestyle measures, for patients without alarm symptoms. Optimization of therapy (improving compliance and timing of PPI doses), or increasing PPI dosage to twice daily in select circumstances, can reduce persistent symptoms. Patients with continued symptoms can be evaluated with endoscopy and tests of esophageal physiology, to better determine their disease phenotype and optimize treatment. Laparoscopic fundoplication, magnetic sphincter augmentation, and endoscopic therapies can benefit patients with well-characterized GERD. Patients with functional diseases that overlap with or mimic GERD can also be treated with neuromodulators (primarily antidepressants), or psychological interventions (psychotherapy, hypnotherapy, cognitive and behavioral therapy). Future approaches to treatment of GERD include potassium-competitive acid blockers, reflux-reducing agents, bile acid binders, injection of inert substances into the esophagogastric junction, and electrical stimulation of the lower esophageal sphincter.

    Laparoscopic 180° anterior fundoplication has been shown to achieve similar reflux control to Nissen fundoplication, with fewer side-effects, up to 5 years. However, there is a paucity of long-term follow-up data on this technique and antireflux surgery in general. This study reports 12-year outcomes of a double-blind RCT comparing laparoscopic Nissen versus 180° laparoscopic anterior fundoplication for gastro-oesophageal reflux disease (GORD). Patients with proven GORD were randomized to laparoscopic Nissen or 180° anterior fundoplication. The 12-year outcome measures included reflux control, dysphagia, gas-related symptoms and patient satisfaction. Measures included scores on a visual analogue scale, a validated Dakkak score for dysphagia and Visick scores. Of the initial 163 patients randomized (Nissen 84, anterior 79), 90 (55·2 per cent) completed 12-year follow-up (Nissen 52, anterior 38). There were no differences in heartburn, dysphagia, gas-related symptoms, patient satisfaction or surgical reintervention rate. Use of acid-suppressing drugs was less common after Nissen than after 180° anterior fundoplication: four of 52 (8 per cent) and 11 of 38 (29 per cent) respectively (P = 0·008). The proportion of patients with absent or only mild symptoms was slightly higher after Nissen fundoplication: 45 of 50 (90 per cent) versus 28 of 38 (74 per cent) (P = 0·044). The two surgical procedures provided similar control of heartburn and post-fundoplication symptoms, with similar patient satisfaction and reoperation rates on long-term follow-up. © 2017 BJS Society Ltd Published by John Wiley & Sons Ltd.

    Attendance in the cervical cancer screening programme is one of the most important factors to lower the risk of contracting the disease. Attendance rates are often low in areas with low socioeconomic status. Charging a fee for screening might possibly decrease attendance in this population. Screening programme coverage is low in low socio-economic status areas in Gothenburg, Sweden, but has increased slightly after multiple interventions in recent years. For many years, women in the region have paid a fee for screening. We studied the effect of abolishing this fee in a trial emanating from the regular cervical cancer screening programme. Individually randomised controlled trial. All 3 124 women in three low-resource areas in Gothenburg, due for screening during the study period, were randomised to receive an offer of a free test or the standard invitation stating the regular fee of 100 SEK (≈11 €). The study was conducted during the first six months of 2013. Attendance was defined as a registered Pap smear within 90 days from the date the invitation was sent out. Attendance did not differ significantly between women who were charged and those offered free screening (RR 0.93; CI 0.85-1.02). No differences were found within the districts or as an effect of age, attendance after the most recent previous invitation or previous experience of smear taking. Abolishment of a modest screening fee in socially disadvantaged urban districts with low coverage, after previous multiple systematic interventions, does not increase attendance in the short term. Other interventions might be more important for increasing attendance in low socio-economic status areas. ClinicalTrials.gov NCT02378324.

    This study estimated the long-term health outcomes, healthcare costs, and cost-effectiveness of rosuvastatin 20 mg therapy in primary prevention of major cardiovascular disease (CVD) in a Swedish population. Based on data from the JUPITER trial, long-term CVD outcomes with rosuvastatin vs no active treatment were estimated for patients with an elevated baseline CVD risk (Framingham CVD score >20%, sub-population of JUPITER population) and for a population similar to the total JUPITER population. Using a decision-analytic model, trial CVD event rates were combined with epidemiological and cost data specific for Sweden. First and subsequent CVD events and death were estimated over a lifetime perspective. The observed relative risk reduction was extrapolated beyond the trial duration. Incremental effectiveness was measured as life-years gained (LYG) and quality-adjusted life-years (QALYs) gained. Treating 100,000 patients with rosuvastatin 20 mg was estimated to avoid 14,692 CVD events over the lifetime (8021 non-fatal MIs, 3228 non-fatal strokes, and 4924 CVD deaths) compared to placebo. This translated into an estimated gain of 42,122 QALYs and 36,865 total life years (LYG). Rosuvastatin was both more effective and less costly over a lifetime perspective, and rosuvastatin is subsequently a dominant alternative compared to no treatment in the assessed population. Using the overall JUPITER population, rosuvastatin was dominant for the lifetime horizon. In the sensitivity analysis, rosuvastatin was the dominant treatment strategy over a 20-year time horizon, and cost-effective with an incremental cost-effectiveness ratio (cost per QALY) of SEK 1783 over a 10-year time horizon. Some model inputs were derived from literature or other data sources, but uncertainty was controlled by sensitivity analyses. Results indicate that rosuvastatin 20 mg treatment is a cost-effective option vs no-treatment in patients with Framingham CVD risk >20% in Sweden and might even be

    Gastroesophageal reflux disease is a highly frequent disorder classically characterized by the presence of heartburn and/or acid regurgitation that improves with drug therapy that reduces acid content in the stomach. However, especially in patients with non-erosive disease, response to proton pump inhibitors is unsatisfactory in approximately 1 out of 3 patients, and consequently, in these patients, it is important to establish a definitive diagnosis and an alternative therapeutic strategy. In the last few years, advances have been made in knowledge of the physiopathology of reflux, such as identification of the role of the acid pocket in producing reflux, technological advances that allow differentiation among acid reflux, non-acid reflux and slightly acid reflux, and advances in the treatment of reflux with drugs that attempt to act on the barrier function of the esophagogastric junction.

    Radionucleotide scintigraphy and esophagoscopy with biopsy were carried out in 101 patients with symptoms strongly suggestive of gastroesophageal reflux (GER) disease. GER was visualized by scintigraphy in 86.1% of the patients. Endoscopic and histologic esophagitis were found in 68.1% and 58.4% of the patients, respectively, whereas both examinations taken together showed evidence of esophagitis in 82%. Histologic evidence of esophagitis was found in nearly all patients with severe endoscopic changes, and in 43.7% of the patients with no endoscopic abnormality. Scintigraphic reflux was demonstrated more frequently (p<0.05) in the patients with severe endoscopic esophagitis (97.5%) than in those with no or only mild endoscopic changes (78.6%). Scintigraphic reflux was found in 91.5% and 78.5% of the patients with and without histologic evidence of esophagitis (p=0.07). 15 of the 18 patients (83.3%) without endoscopic and histologic abnormalities in the esophagus had scintigraphic evidence of reflux. The present study strongly supports the clinical significance of scintigraphy in GER disease and confirms that esophageal biopsy specimens increase the sensitivity of endoscopic evaluation

    2013-01-01

    Gastro-oesophageal reflux disease is generally considered to be one of the commonest causes of chronic cough, however randomised controlled trials of proton pump inhibitors have often failed to support this notion. This article reviews the most recent studies investigating the mechanisms thought to link reflux and cough, namely laryngo-pharyngeal reflux, micro-aspiration and neuronal cross-organ sensitisation. How recent evidence might shed light on the failure of acid suppressing therapies and suggest new approaches to treating reflux related cough are also discussed. PMID:23590893

    Contrast-enhanced voiding urosonography (ceVUS) is widely used outside the United States to diagnose vesicoureteral reflux (VUR) in children and is highly sensitive while avoiding exposure to ionizing radiation. At the onset of this study, two ultrasound (US) contrast agents were available in the United States. Pediatric safety data for intravenous administration was published for one, Optison™. This study aimed to evaluate the diagnostic performance and safety of ceVUS using Optison™ and compare its diagnostic efficacy with voiding cystourethrogram (VCUG) for VUR detection and grading in children. The United States Food and Drug Administration and institutional Investigational New Drug authorizations were obtained to conduct a prospective comparative study of ceVUS with Optison™ and VCUG. CeVUS was performed with intravesical administration of 0.2% Optison™/normal saline solution. A standard VCUG followed. Safety assessment included physical examination, and heart rate, pulse oximetry and adverse reactions monitoring before, during and immediately after the examinations. A follow-up questionnaire was completed by telephone 48-h after the studies. Sixty-two pelviureteric units were studied in 30 patients with a mean age of 3.5 years (range: 0.1-17 years) including 21 girls and 9 boys. No severe adverse events occurred. All patients had normal heart rate and blood oxygenation saturation prior to, during and after the studies. At the 48-h follow-up, one patient (3.3%) reported transient dysuria. Taking the VCUG as the reference standard, ceVUS had a sensitivity of 91.7% (95%; confidence interval [CI]: 61.5%-99.8%) and specificity of 98% (95%; CI: 89.4%-99.9%). The concordance between ceVUS and VCUG for VUR detection and grading was 84.3% and 81.8%, respectively. VUR grades were discrepant in 4/11 refluxing pelviureteric units, with VCUG upgrading VUR in 2. Detection of VUR with Optison™ ceVUS was comparable to VCUG without exposure to ionizing radiation

    Gastroesophageal reflux disease (GERD) is a condition that develops when the reflux of stomach contents into the esophagus causes troublesome symptoms, esophageal injury, and/or complications. Use of proton pump inhibitors (PPI) remains the standard therapy for GERD and is effective in most patients. Those whose symptoms are refractory to PPIs should be evaluated further and other treatment options should be considered, according to individual patient characteristics. Response to PPIs could be total (no symptoms), partial (residual breakthrough symptoms), or absent (no change in symptoms). Patients experiencing complete response do not usually need further management. Patients with partial response can be treated surgically or by using emerging endoscopic therapies. Patients who exhibit no response to PPI need further evaluation to rule out other causes. PMID:25274499

Cricopharyngeal muscle incoordination, assessed cineradiographically, was revealed in 5 of 41 patients (12%) without and 17 of 43 patients (40%) with gastroesophageal reflux assessed clinically (p<0.05). Thus, there was a postive correlation between dysfunction of the cricopharyngeal muscle and gastroesophageal reflux. There was no correlation with other types of pharyngeal dysfunction. Our results support the assumption of a positive relationship between gastroesophageal reflux and pharyngeal function in terms of cricopharyngeal dysfunction. The pathogenesis of this relation was, however, not revealed. (orig.)

    2014-01-01

    Full Text Available Introduction Laryngopharyngeal reflux (LPR is a highly prevalent disease and commonly encountered in the otolaryngologist's office. Objective To review the literature on the diagnosis and treatment of LPR. Data Synthesis LPR is associated with symptoms of laryngeal irritation such as throat clearing, coughing, and hoarseness. The main diagnostic methods currently used are laryngoscopy and pH monitoring. The most common laryngoscopic signs are redness and swelling of the throat. However, these findings are not specific of LPR and may be related to other causes or can even be found in healthy individuals. Furthermore, the role of pH monitoring in the diagnosis of LPR is controversial. A therapeutic trial with proton pump inhibitors (PPIs has been suggested to be cost-effective and useful for the diagnosis of LPR. However, the recommendations of PPI therapy for patients with a suspicion of LPR are based on the results of uncontrolled studies, and high placebo response rates suggest a much more complex and multifactorial pathophysiology of LPR than simple acid reflux. Molecular studies have tried to identify biomarkers of reflux such as interleukins, carbonic anhydrase, E-cadherin, and mucin. Conclusion Laryngoscopy and pH monitoring have failed as reliable tests for the diagnosis of LPR. Empirical therapy with PPIs is widely accepted as a diagnostic test and for the treatment of LPR. However, further research is needed to develop a definitive diagnostic test for LPR.

    Background Obesity is a risk factor for asthma. Obese asthmatics often have poor asthma control and respond poorly to therapy. It has been suggested that co-morbidities associated with obesity, such as reflux and obstructive sleep apnea, could be important factors contributing to poor asthma control in obese patients. Objectives The purpose of this study was to determine if (i) reflux and/or (ii) symptoms of sleep apnea contribute to poor asthma control in obesity. Methods We studied asthmatic subjects participating in a trial of reflux treatment. Participants underwent baseline evaluation of asthma symptoms and lung function. 304 participants underwent esophageal pH probe testing. 246 participants were evaluated for obstructive sleep apnea symptoms. Results Of 402 participants in this trial, 51% were obese. Role of reflux in asthma control Those with higher body mass index reported a higher prevalence of reflux symptoms, but the prevalence of pH probe acid reflux was similar in all groups. Reflux was not associated with measures of asthma control in obese patients. Role of obstructive sleep apnea in asthma control Symptoms and self-report of obstructive sleep apnea were more common with increasing body mass index and associated with worse asthma control as measured by the Juniper Asthma Control Questionnaire and Asthma Symptom Utility Index. Conclusions Our data suggest that obstructive sleep apnea, but not gastroesophageal reflux disease may contribute significantly to poor asthma control in obese patients. PMID:21819338

    Full Text Available Aim: This study aimed to identify the differences between primary and secondary vesicoureteric reflux (VUR and the effect of associated bladder abnormalities on kidney function. Patients and Methods: We retrospectively reviewed the medical records of children with VUR who were followed up at King Abdulaziz University Hospital from January 2005 to December 2010. The review included results of radiological investigations and kidney function tests. We used Chi-square test for statistical analysis and paired t-test to compare group means for initial and last creatinine levels. Results: Ninety-nine children were included in this study. Twenty (20.2% had primary VUR, 11 had high-grade VUR, while 9 had low-grade reflux. All children with low-grade VUR had normal dimercaptosuccinic acid (DMSA. Renal scars were present in 72% of the children with high-grade VUR. The mean creatinine levels (initial and last for both groups were normal. Seventy-nine (79.8% children had secondary VUR, which was due to posterior urethral valves (PUV (46.8%, neurogenic bladder caused by meningomyelocele (25.3%, non-neurogenic neurogenic bladder (NNB (21.5%, or neurogenic bladder associated with prune belly syndrome (6.3%. Children with NNB, meningomyelocele and PUV had high creatinine at presentation with no considerable worsening of their kidney functions during the last visit. Renal scars were present in 49.4% of the children with secondary VUR. Conclusion: Children with primary VUR and normal bladder had good-functioning kidneys, while those with secondary VUR associated with abnormal bladder caused by NNB, spina bifida or PUV had abnormal kidney functions. DMSA scans were useful in predicting higher grades of VUR in children with primary reflux.

The role of the intra-renal reflux ( Hodson ) and the Big Bang Theory ( Ransley ) are discussed as the data from animal experiments. The role of the sterile reflux and of the segmental hypoplasia is relatively less important. The actual management of vesico-ureteric reflux treatment is questioned.

    There continues to be significant controversy related to diagnostic testing for gastroesophageal reflux disease (GERD). Clearly, barium contrast fluoroscopy is superior to any other test in defining the anatomy of the upper gastrointestinal (UGI) tract. Although fluoroscopy can demonstrate gastroesophageal reflux (GER), this observation does not equate to GERD. Fluoroscopy time should not be prolonged to attempt to demonstrate GER during barium contrast radiography. There are no data to justify prolonging fluoroscopy time to perform provocative maneuvers to demonstrate reflux during barium contrast UGI series. Symptoms of GERD may be associated with physiologic esophageal acid exposure measured by intraesophageal pH monitoring, and a significant percentage of patients with abnormal esophageal acid exposure have no or minimal clinical symptoms of reflux. Abnormal acid exposure defined by pH monitoring over a 24-h period does not equate to GERD. In clinical practice presumptive diagnosis of GERD is reasonably assumed by substantial reduction or elimination of suspected reflux symptoms during therapeutic trial of acid reduction therapy.

    When patients have symptomatic gastroesophageal reflux disease, their symptoms usually respond to conventional therapeutic measures. In some patients, however, the symptoms may persist despite the application of standard treatment regimens. It is in these instances that the clinician may employ extensive diagnostic tests to determine the cause of the patient's complaints. Because the introduction of gastroesophageal scintigraphy, a number of other techniques were employed to evaluate gastroesophageal reflux. These include barium esophagography, barium cineesophagography; endoscopy; esophageal mucosal biopsy; esophageal manometry; the acid-clearance test; and acid-reflux testing. Each of the nonscintigraphic techniques has a limitation either in its sensitivity or in the requirement for endogastric intubation. In addition, with the exception of the scintigraphic method, none of the tests permits quantitation of reflux

    By means of esophageal transit scintigram using 99m Tc-DTPA, 15 patients (13 esophageal carcinomas and 2 cardia carcinomas) were studied, in whom esophagogastric anastomosis was done according to the posterior invagination anastomosis technique we had devised. In all 8 patients with anastomosis at cervical region, gastroesophageal reflux was not seen on both scintigrams before and after meals, and the average pressure gradient of high pressure zone at anastomosis was 39.8 cmH 2 O. In 2 of 7 patients with intrathoracic anastomosis, the scintigram before meals showed severe reflux. and the endoscopic findings showed diffuse and moderate erosion in the esophageal mucosa. The average pressure gradient across the anastomosis was 6.5 cmH 2 O. In these 2 patients, the new fornix with a sharp angle of His was not formed. In the remaining 5 patients with intrathoracic anastomosis, reflux was not seen on the scintigram before meals. However, in 2 of them, the scintigram after meal and endoscopic examination revealed mild reflux and mild esophagitis respectively. Furthermore in one patient very mild reflux was observed only on the scintigram after meals but the endoscopic findings showed the normal esophageal mucosa. In these 5 patients, the average pressure gradient across the anastomosis was 17.0 cmH 2 O, which was significantly higher (p<0.01) than that in 2 patients with severe reflux and was significantly lower (p<0.01) than the mean value of high pressure zone in 8 patients with cervical anastomosis. In conclusion, it is presumed that the formation of a large fornix enough to store food and a sharp angle of His are important factors in maintaining an anti-reflux mechanism. The esophageal transit scintigram was proved to be an excellent technique in detecting and evaluating quantitatively gastroesophageal reflux. (author)

Their size, shape, and distribution provide a variable radiographic appearance that must be distinguished from other causes of intrarenal reflux. When reflux filling of dysplastic structures is incomplete, the radiographic findings do not fully represent the severity of anatomic abnormality

    Despite the frequency with which antireflux procedures are performed, decisions about gastroesophageal reflux disease treatment remain challenging. Several factors contribute to the difficulties in managing gastroesophageal reflux. First, the distinction between physiologic and pathologic gastroesophageal reflux (gastroesophageal reflux disease-GERD) is not always clear. Second, measures of the extent of gastroesophageal reflux often poorly correlate to symptoms or other complications attributed to reflux in infants and children. A third challenge is that the outcome of antireflux procedures, predominately fundoplications, are relatively poorly characterized. All of these factors contribute to difficulty in knowing when to recommend antireflux surgery. One of the manifestations of the uncertainties surrounding GERD is the high degree of variability in the utilization of pediatric antireflux procedures throughout the United States. Pediatric surgeons are frequently consulted for GERD and fundoplication, uncertainties notwithstanding. Although retrospective series and anecdotal observations support fundoplication in some patients, there are many important questions for which sufficient high-quality data to provide a clear answer is lacking. In spite of this, surgeons need to provide guidance to patients and families while awaiting the development of improved evidence to aid in these recommendations. The purpose of this article is to define what is known and what is uncertain, with an emphasis on the most recent evidence. Copyright © 2016 Elsevier Inc. All rights reserved.

    Proton pump inhibitors and histamine H2 receptor antagonists are two of the most commonly prescribed drug classes for pediatric gastroesophageal reflux disease, but their efficacy is controversial. Many patients are treated with these drugs for atypical manifestations attributed to gastroesophageal reflux, even that causal relation is not proven. To evaluate the use of proton pump inhibitors and histamine H2 receptor antagonists in pediatric gastroesophageal reflux disease through a systematic review. A systematic review was performed, using MEDLINE, EMBASE and Cochrane Central Register of Controlled Trials databases. The search was limited to studies published in English, Portuguese or Spanish. There was no limitation regarding date of publication. Studies were considered eligible if they were randomized-controlled trials, evaluating proton pump inhibitors and/or histamine H2 receptor antagonists for the treatment of pediatric gastroesophageal reflux disease. Studies published only as abstracts, studies evaluating only non-clinical outcomes and studies exclusively comparing different doses of the same drug were excluded. Data extraction was performed by independent investigators. The study protocol was registered at PROSPERO platform (CRD42016040156). After analyzing 735 retrieved references, 23 studies (1598 randomized patients) were included in the systematic review. Eight studies demonstrated that both proton pump inhibitors and histamine H2 receptor antagonists were effective against typical manifestations of gastroesophageal reflux disease, and that there was no evidence of benefit in combining the latter to the former or in routinely prescribing long-term maintenance treatments. Three studies evaluated the effect of treatments on children with asthma, and neither proton pump inhibitors nor histamine H2 receptor antagonists proved to be significantly better than placebo. One study compared different combinations of omeprazole, bethanechol and placebo for the

    This relationship between gastroesophageal reflux and airway disorders is complex, possibly bidirectional, and not clearly defined. The tools used to investigate gastroesophageal reflux are mostly informative about involvement of gastroesophageal reflux within the gastrointestinal tract, although they are often utilized to study the relationship between gastroesophageal reflux and airway issues with are suspected to occur in relation to reflux. These modalities often lack specificity for reflux-related airway disorders. Co-incidence of gastroesophageal reflux and airway disorders does not necessarily infer causality. While much of our focus has been on managing acidity, controlling refluxate is an area that has not been traditionally aggressively pursued. Our management approach is based on some of the evidence presented, but also often from a lack of adequate study to provide further guidance. Copyright © 2018 Mosby, Inc. All rights reserved.

  17. Gastroesophageal Reflux Disease and Tooth Erosion

    Full Text Available The increasing prevalence of gastroesophageal reflux disease (GERD in children and adults, and of “silent refluxers” in particular, increases the responsibility of dentists to be alert to this potentially severe condition when observing unexplained instances of tooth erosion. Although gastroesophageal reflux is a normal physiologic occurrence, excessive gastric and duodenal regurgitation combined with a decrease in normal protective mechanisms, including an adequate production of saliva, may result in many esophageal and extraesophageal adverse conditions. Sleep-related GERD is particularly insidious as the supine position enhances the proximal migration of gastric contents, and normal saliva production is much reduced. Gastric acid will displace saliva easily from tooth surfaces, and proteolytic pepsin will remove protective dental pellicle. Though increasing evidence of associations between GERD and tooth erosion has been shown in both animal and human studies, relatively few clinical studies have been carried out under controlled trial conditions. Suspicion of an endogenous source of acid being associated with observed tooth erosion requires medical referral and management of the patient as the primary method for its prevention and control.

    Gastro-oesophageal reflux, either singly or in association with postnasal drip and/or asthma is considered to be a cause of chronic cough. The amount and nature of gastro-oesophageal reflux however is often normal with acid suppression having very little, if any therapeutic effect in these patients. This review examines the challenges posed when exploring the reflux-cough link, and discusses the merits and limitations of the proposed mechanisms of reflux leading to cough.

    Background/Aims Available data about reflux patterns and symptom determinants in the gastroesophageal reflux disease (GERD) subtypes off proton pump inhibitor (PPI) therapy are lacking. We aimed to evaluate reflux patterns and determinants of symptom perception in patients with GERD off PPI therapy by impedance-pH monitoring. Methods We retrospectively reviewed the impedance-pH data in patients diagnosed as GERD based on results of impedance-pH monitoring, endoscopy and/or typical symptoms. The characteristics of acid and weakly acidic reflux were evaluated. Symptomatic and asymptomatic reflux were compared according to GERD subtypes and individual symptoms. Results Forty-two patients (22 males, mean age 46 years) were diagnosed as GERD (17 erosive reflux disease, 9 pH(+) non-erosive reflux disease [NERD], 9 hypersensitive esophagus and 7 symptomatic NERD). A total of 1,725 reflux episodes were detected (855 acid [50%], 857 weakly acidic [50%] and 13 weakly alkaline reflux [reflux was more frequently symptomatic and bolus clearance was longer compared with weakly acidic reflux. In terms of globus, weakly acidic reflux was more symptomatic. Symptomatic reflux was more frequently acid and mixed reflux; these associations were more pronounced in erosive reflux disease and symptomatic NERD. The perception of regurgitation was related to acid reflux, while that of globus was more related to weakly acidic reflux. Conclusions In patients not taking PPI, acid reflux was more frequently symptomatic and had longer bolus clearance. Symptomatic reflux was more frequently acid and mixed type; however, weakly acidic reflux was associated more with globus. These data suggest a role for impedance-pH data in the evaluation of globus.

    To analyze our series of primary congenital diverticula (PCD) and their association with vesicoureteral reflux. We have taken care of 23 children with PCD. Eleven of them had big diverticula (> 2 cm) and twelve small. In the first group, 4 children had vesicoureteral reflux and 5 in the second group. In group A, ureteral reimplantation was performed at the time of diverticulum excision. Nor diverticula neither refluxes were operated in group B. We analyze separately results in both groups. Group A: Patients were operated including diverticulum excision. There were not recurrences except in one case with Ehler-Danlos Syndrome. No reimplanted ureter showed postoperative reflux. Nevertheless, one case with multiple bladder diverticula without reflux presented reflux after the excision of several diverticula without reimplantation. Group B: Small diverticula did not undergo surgery Spontaneous outcome of reflux was similar to that of the general population without diverticula. Bladder diverticula are frequently associated with vesicoureteral reflux. The presence of reflux is not an absolute condition for surgical or endoscopic treatment. When diverticula are big in size (Group A) the indication for surgery comes from recurrent infection or voiding disorders, not from reflux. If they undergo surgery, ureteral reimplantation is performed in the case they had reflux or for technical reasons like bladder wall weakness. When diverticula are small (Group B) the presence of reflux does not condition treatment, being the rate of spontaneous resolution similar to the general population.

    2017-08-01

    Asthma and gastroesophageal reflux (GORD) are widespread and potentially coexisting diseases. Incidence and prevalence of concomitant asthma and GORD are highly variable among studies. This is mainly due to the heterogeneity of study designs. To explain a potential link, some pathophysiological anomaly has been proposed such as the altered pressure gradient between thorax and abdomen, the parasympathetic reflex, the heightened bronchial reactivity and chemical effects of microaspired gastric juice. An accurate diagnosis of asthma and GORD is pivotal in order to lead effective treatment and to reach a significant positive outcome, in terms of quality of life and respiratory function amelioration. Gastroenterological evaluation of GORD includes the empiric proton pump-inhibitors (PPIs) trial, the esophageal pH monitoring and endoscopic evaluation. Besides spirometric investigations, pulmonologist have more specific examens such as bronchoalveolar lavage and exhaled breath condensate. Actually, international recommendations regarding the management of asthma suggest the assessment of potential comorbidities, including the presence of GORD, mostly in children, only in patients with normal pulmonary functional tests with frequent respiratory symptoms, and in case of uncontrolled asthma. Symptomatic gastro-esophageal reflux patients should be treated, but those with uncontrolled asthma should not be treated with anti-reflux drugs unless they are symptomatic for reflux. This review explores the state of the art about the pathogenesis and the management of the relationship between asthma and GORD.

    Full Text Available Background Gastroesophageal reflux disease (GERD is very common in developed world, with the prevalence of disease is between 6 and 20%. Pathologic reflux can provoke not only typical symptoms (heartburn and regurgitation but also atypical symptoms and diseases of extraoesophageal organs (pulmonary, ENT, mouth. High prevalence of GERD in patients with unexplained chest pain, asthma, chronic cough, chronic laryngitis, hoarsness and dental erosions is not a proof of causality. GERD can cause these diseases with reflux of acid and pepsin into pharynx, larynx, lungs and mouth (reflux theory or through vasovagal mechanisms (reflex theory. Conclusions Good therapeutic success with medical or operative treatment in early methodologically not well conducted studies has not been completely proven in double-blind placebo controlled studies. GERD is an ethyological reason for these extraoesophageal symptoms and diseases in an approximately one third of patients. With diagnostic modalities that we have now, we cannot clearly define in which patient is GERD is an ethyologic factor or a contributer, before we start the treatment. In patients suspected of having GERD, there is therapeutic option of a trial with high dose of proton pump inhibitor for 3 to 6 months. In other patients with low clinical suspicion of GERD, 24-hour pH testing should be done first.

    To compare the cost-effectiveness of therapy of gastroesophageal reflux disease with esomeprazole and other proton pump inhibitors (PPIs) in Poland. Studies comparing esomeprazole with other PPIs in the treatment of erosive esophagitis, non-erosive reflux disease and gastroesophageal reflux disease maintenance therapy were systematically reviewed. 9 randomized clinical trials were selected, meta-analyses were conducted. Cost data derived from Polish Ministry of Health and Pharmacies in Wroclaw. In the treatment of erosive esophagitis esomeprazole was significantly more effective than other PPIs. Both for 4- and 8-week therapy respective incremental cost-effectiveness ratio values were acceptably low. Differences in effectiveness of non-erosive reflux disease therapy were not significant. The replacement of pantoprazole 20 mg with more effective esomeprazole 20 mg in the 6-month maintenance therapy was associated with a substantially high incremental cost-effectiveness ratio.

  12. Radiologic diagnosis of gastro-oesophageal reflux

    In 149 patients, a standardized radiologic method for the detection of gastro-oesophageal reflux was applied and compared with the results obtained at endoscopy and by a manometric reflux test. Radiologic reflux was recorded in 53 patients, of whom 25 had reflux without abdominal compression and 51 with compression. At least one of the other two types of examination disclosed pathologic conditions in all but 2 of 53 patients. Oesophagitis was significantly more severe among the patients with reflux observed at radiography. The presence of hiatal incompetence with reflux only to the hiatal hernia but not to the oesophagus was not a strong indicator of gastro-oesophageal reflux disease. Hiatal hernia was present in a significantly larger number of the patients with reflux at radiography than in those without reflux. Increased width of the hiatus gave stronger evidence for reflux disease than in patients with a normal hiatus. Thus, the width of the hiatus also had a bearing on the diagnosis of gastro-oesophageal reflux disease.

    In a prospective study, 26 patients with symptoms of reflux oesophagitis underwent a barium examination for gastro-oesophageal reflux after food stimulation, and endoscopy with biopsy from different levels of the oesophagus. Radiologic grading of the gastro-oesophageal reflux depending on the height of the reflux into the oesophagus was performed, and this was correlated to the microscopic appearance at different levels in the oesophagus. Complete agreement between the radiologic grading and the histology was found in 69 per cent of the cases, and when gastro-oesophageal reflux was demonstrated the agreement was 75 per cent. Accordingly, the results showed a good accordance between the two variants, indicating that the height of the reflux during the food stimulated test may be truly indicative of the reflux height under non-test conditions.

    Duodenogastric and gastroesophageal refluxes can be accurately detected by hepatobiliary and gastroesophageal scintigraphy. These procedures are non-invasive and easy to perform. Practical details and evaluation are described. Subsequent to a review of diagnostic results, indications are discussed. Both techniques should be applied in cases where morphological examinations did not yield any pathologic result and clinical symptoms are suggestive for functional disturbances.

    Gastroesophageal reflux disease (GERD) is an emerging disease, and can impair quality of life and sleep. This study aimed to investigate whether GERD patients with different timings of reflux symptoms have different clinical characteristics. This study prospectively enrolled individuals who underwent upper gastrointestinal endoscopy during a health checkup. Each participant completed all questionnaires including Reflux Disease Questionnaire, Nighttime GERD questionnaire, Pittsburg Sleep Quality Index, Taiwanese Depression Questionnaire, and State-Trait Anxiety Inventory. Combined reflux was defined as the timing of reflux symptoms occurring at both daytime and nighttime. A total of 2604 participants were enrolled. Of them, 651 symptomatic GERD patients, according to the Reflux Disease Questionnaire score, were recruited for final analysis. Of them, 224 (34.4%) had erosive esophagitis on endoscopy. According to the timing of reflux symptoms, 184 (28.3%) were assigned to the daytime reflux group, 71 (10.9%) to the nighttime reflux group, and 396 (60.8%) to the combined reflux group. In post hoc analysis, the combined reflux group had a significantly higher Reflux Disease Questionnaire score than the daytime reflux group (p reflux groups had higher body mass index and longer duration (> 12 years) of education than the daytime reflux group (p reflux of have more troublesome symptoms than those with daytime reflux. GERD patients with different timings of reflux symptoms have different clinical characteristics in terms of body mass index and duration of education, but not in terms of esophageal inflammation, quality of sleep, and psychosocial status.

    in males and females. Bilateral reflux prevalence is similar to unilateral reflux. Grade I-II reflux is estimated to be present in 16.7% and grade III-V reflux in 9.8% of screened patients. The estimate for renal cortical abnormalities overall is 19.3%, with 27.8% having renal damage in cohorts of symptomatic and asymptomatic children combined. In asymptomatic siblings only the rate of renal damage is 14.4%. There are presently no randomized, controlled trials of treated vs untreated screened siblings with vesicoureteral reflux to evaluate health outcomes as spontaneous resolution, decreased rates of urinary infection, pyelonephritis or renal scarring. In screened populations with prenatal hydronephrosis the prevalence of vesicoureteral reflux is 16.2%. Reflux in the contralateral nondilated kidney accounted for a mean of 25.2% of detected cases for a mean prevalence of 4.1%. In patients with a normal postnatal renal ultrasound the prevalence of reflux is 17%. The prenatal anteroposterior renal pelvic diameter was not predictive of reflux prevalence. A diameter of 4 mm is associated with a 10% to 20% prevalence of vesicoureteral reflux. The prevalence of reflux is statistically significantly greater in females (23%) than males (16%) (p=0.022). Reflux grade distribution is approximately a third each for grades I-II, III and IV-V. The estimate of renal damage in screened infants without infection is 21.8%. When stratified by reflux grade renal damage was estimated to be present in 6.2% grade I-III and 47.9% grade IV-V (p <0.0001). The risk of urinary tract infection in patients with and without prenatal hydronephrosis and vesicoureteral reflux could not be determined. The incidence of reported urinary tract infection in patients with reflux was 4.2%. The meta-analysis provided meaningful information regarding screening for vesicoureteral reflux. However, the lack of randomized clinical trials for screened patients to assess clinical health outcomes has made evidence

    Introduction Low back pain (LBP) is a major health problem commonly requiring healthcare. In Sweden, there is a call from healthcare practitioners (HCPs) for the development, implementation and evaluation of a best practice primary healthcare model for LBP. Aims (1) To improve and understand the mechanisms underlying changes in HCP confidence, attitudes and beliefs for providing best practice coherent primary healthcare for patients with LBP; (2) to improve and understand the mechanisms underlying illness beliefs, self-care enablement, pain, disability and quality of life in patients with LBP; and (3) to evaluate a multifaceted and sustained implementation strategy and the cost-effectiveness of the BetterBack☺ model of care (MOC) for LBP from the perspective of the Swedish primary healthcare context. Methods This study is an effectiveness-implementation hybrid type 2 trial testing the hypothesised superiority of the BetterBack☺ MOC compared with current routine care. The trial involves simultaneous testing of MOC effects at the HCP, patient and implementation process levels. This involves a prospective cohort study investigating implementation at the HCP level and a patient-blinded, pragmatic, cluster, randomised controlled trial with longitudinal follow-up at 3, 6 and 12 months post baseline for effectiveness at the patient level. A parallel process and economic analysis from a healthcare sector perspective will also be performed. Patients will be allocated to routine care (control group) or the BetterBack☺ MOC (intervention group) according to a stepped cluster dogleg structure with two assessments in routine care. Experimental conditions will be compared and causal mediation analysis investigated. Qualitative HCP and patient experiences of the BetterBack☺ MOC will also be investigated. Dissemination The findings will be published in peer-reviewed journals and presented at national and international conferences. Further national dissemination and

    Medical therapy of gastroesophageal reflux disease (GERD) is based on the use of proton pump inhibitors (PPIs) as first choice treatment. Despite their effectiveness, about 20-30% of patients report an inadequate response and alternative drugs are required. Areas covered: This review provides an overview of current pharmacotherapy for treating GERD by showing the results of PPIs, reflux inhibitors, antidepressants and mucosa protective medications. Expert opinion: Medical therapy of GERD does not definitely cure the disease, because even PPIs are not able to change the key factors responsible for it. However, they remain the mainstay of medical treatment, allowing us to alleviate symptoms, heal esophagitis and prevent complications in the majority of cases. Nevertheless, many patients do not respond, because acid does not play any pathogenetic role. Prokinetics and reflux inhibitors have the potential to control motor abnormalities, but the results of clinical trials are inconsistent. Antidepressant drugs are effective in specific subgroups of NERD patients with visceral hypersensitivity, but larger, controlled clinical studies are necessary. Protective drugs or medical devices have been recently adopted to reinforce mucosal resistance and preliminary trials have confirmed their efficacy either combined with or as add-on medication to PPIs in refractory patients.

  20. The management of gastro-oesophageal reflux disease.

    2016-02-01

    If there are no features of serious disease, suspected gastro-oesophageal reflux disease can be initially managed with a trial of a proton pump inhibitor for 4-8 weeks. This should be taken 30-60 minutes before food for optimal effect. Once symptoms are controlled, attempt to withdraw acid suppression therapy. If symptoms recur, use the minimum dose that controls symptoms. Patients who have severe erosive oesophagitis, scleroderma oesophagus or Barrett's oesophagus require long-term treatment with a proton pump inhibitor. Lifestyle modification strategies can help gastro-oesophageal reflux disease. Weight loss has the strongest evidence for efficacy. Further investigation and a specialist referral are required if there is no response to proton pump inhibitor therapy. Atypical symptoms or signs of serious disease also need investigation.

    In a prospective study a barium examination combined with food stimulation was compared with the acid reflux test in 30 consecutive patients with symptoms of gastro-oesophageal reflux. Both methods were further compared with endoscopy and histology. Gastro-oesophageal reflux could be demonstrated by the radiologic examination in 22 patients and by the acid reflux test in 23 patients. By combining the two methods gastro-oesophageal reflux could be demonstrated in 27 patients. Comparing the two methods with symptoms, endoscopy, and histology they seemed to be of equal value. Accordingly, a food-stimulated barium examination is recommended as the first method for demonstrating gastro-oesophageal reflux because it is simple and well-tolerated by the patient. (orig.)

    Associations of gastroesophageal reflux disease (GERD) with extraesophageal manifestations, such as chronic cough, asthma, and laryngitis, are reported frequently, and there is a strong evidence of biological plausibility in support of this relationship. On the other hand, extraesophageal reflux disease (EERD) is usually multifactorial in nature with reflux being just one of the several potential contributing cofactors. Moreover, the accuracy of currently available diagnostic tests for EERD is suboptimal, and therefore the causal relationship between GERD and EERD remains far from being conclusively proven. In addition, there is a general paucity of data supporting a beneficial effect of anti-reflux treatments on symptoms of patients with suspected EERD. Therefore, diagnostic as well as therapeutic management of EERD remains largely empirical. Current guidelines suggest an initial empiric trial of proton pump inhibitors in patients without alarm features, who present also typical GERD symptoms. For those patients who improve with PPIs, GERD is presumed to be the etiology. In patients with refractory reflux, combined impedance/pH monitoring might provide the single best strategy for evaluating reflux symptoms. In this context, as symptoms ascribable to GERD may depend on other causes, investigations that excludes GERD can help to redirect the diagnostic and treatment efforts to other pathological conditions. The present review intends to discuss the current state of knowledge regarding the challenging diagnostic and therapeutic management of patients with suspected EERD, emphasizing the points of strengths and limitations of currently available diagnostic options, and to provide an update on major diagnostic innovations in this area.

    AIM: To clarify the pathogenesis of gastroesophageal reflux disease symptoms in non-erosive reflux disease (NERD) patients. METHODS: Thirty-five NERD patients with persistent symptoms, despite taking rabeprazole 10 mg twice daily for at least 8 wk, were included in this study. All patients underwent 24 h combined impedance - pH on rabeprazole. The symptom index (SI) was considered to be positive if ≥ 50%, and proximal reflux episodes were determined when reflux reached 15 cm above the proximal margin of the lower esophageal sphincter. RESULTS: In 14 (40%) SI-positive patients, with liquid weakly acid reflux, the occurrence rate of reflux symptoms was significantly more frequent in proximal reflux episodes (46.7%) than in distal ones (5.7%) (P acid reflux, there were no significant differences in the occurrence rate of reflux symptoms between proximal reflux episodes (38.5%) and distal ones (20.5%) (NS). With mixed liquid-gas weakly acid reflux, the occurrence rate of reflux symptoms in proximal reflux episodes was significantly more frequent (31.0%) than in distal reflux ones (3.3%) (P acid reflux, there were no significant differences in the occurrence rate of reflux symptoms between proximal reflux episodes (29.4%) and distal ones (14.3%) (NS). CONCLUSION: The proximal extent of weakly acidic liquid and mixed liquid-gas reflux is a major factor associated with reflux perception in SI-positive patients on proton pump inhibitor therapy.

    Sixty-five symptomatic infants and children underwent radionuclide gastroesophagography, acid reflux testing, and barium esophagography with water-siphon testing to evaluate the clinical efficacy of the scintigraphic technique in detecting gastroesophageal reflux. After ingesting /sup 99m/Tc sulfur colloid in fruit juice, patients rested beneath the gamma camera for 30 to 60 min while esophageal activity was monitored continuously. By using the acid reflux test as a standard of comparison, the senstivity of radionuclide gastroesophagography was 75%. Because of its physiologic nature, low radiation exposure, and convenience, radionuclide gastroesophagography warrants further evaluation as a screening test for gastroesophageal reflux

    The γ-aminobutyric acid type B-receptor agonist lesogaberan (AZD3355) has been developed for use in patients with gastroesophageal reflux disease (GERD) symptoms despite proton pump inhibitor (PPI) therapy (partial responders). This study aimed to explore the dose-response effect of lesogaberan on reflux episodes in partial responders. In this randomized, single-centre, double-blind, crossover, placebo-controlled study, partial responders taking optimised PPI therapy were given 30, 90, 120 and 240 mg doses of lesogaberan. Each dose was given twice (12 h apart) during a 24-h period, during which impedance-pH measurements were taken. Twenty-five patients were included in the efficacy analysis and 27 in the safety analysis. The effect of lesogaberan on the mean number of reflux episodes was dose-dependent, and all doses significantly reduced the mean number of reflux episodes relative to placebo. Lesogaberan also dose-dependently reduced the mean number of acid reflux episodes (except the 30 mg dose) and weakly acid reflux episodes (all doses) significantly, relative to placebo. Regardless of dose, lesogaberan had a similar effect on the percentage of time with esophageal pH < 4 [mean reduction: 68.5% (30 mg), 54.2% (90 mg), 65.9% (120 mg), 72.1% (240 mg); p < 0.05 except 90 mg dose]. No adverse events led to discontinuation and no serious adverse events occurred during active treatment. Lesogaberan inhibited reflux in a dose-dependent manner in partial responders taking optimised PPI therapy, and these effects were significant versus placebo. All lesogaberan doses were well tolerated and were not associated with clinically relevant adverse events. ClinicalTrials.gov identifier: NCT01043185.

    To identify which technique is better for avoiding biliary reflux and gastritis between uncut Roux-en-Y and Billroth II reconstruction. A total of 158 patients who underwent laparoscopy-assisted distal gastrectomy for gastric cancer at the First Hospital of Jilin University (Changchun, China) between February 2015 and February 2016 were randomized into two groups: uncut Roux-en-Y (group U) and Billroth II group (group B). Postoperative complications and relevant clinical data were compared between the two groups. According to the randomization table, each group included 79 patients. There was no significant difference in postoperative complications between groups U and B (7.6% vs 10.1%, P = 0.576). During the postoperative period, group U stomach pH values were lower than 7 and group B pH values were higher than 7. After 1 year of follow-up, group B presented a higher incidence of biliary reflux and alkaline gastritis. However, histopathology did not show a significant difference in gastritis diagnosis ( P = 0.278), and the amount of residual food and gain of weight between the groups were also not significantly different. At 3 mo there was no evidence of partial recanalization of uncut staple line, but at 1 year the incidence was 13%. Compared with Billroth II reconstruction, uncut Roux-en-Y reconstruction is secure and feasible, and can effectively reduce the incidence of alkaline reflux, residual gastritis, and heartburn. Despite the incidence of recanalization, uncut Roux-en-Y should be widely applied.

    Vesicoureteral reflux (VUR) remains the most interesting topic of pediatric urology due to the dynamic nature of recent controversial publications. Starting from the need for a diagnosis to the necessity and effectiveness of treatment in preventing scars, VUR remains in the mist. Although recent strong evidence helped as fog lights in this blurriness, more data are required for achieving crystal clearance. This article aims to summarize and discuss the current state of the evidence regarding VUR management. To provide a comprehensive synthesis of the main evidence in the literature on the current and contemporary management of VUR in children; to discuss conservative management with continuous antibiotic prophylaxis (CAP), especially its effectiveness and safety; and to review the current evidence regarding contemporary surgical techniques. We conducted a nonsystematic review of the literature using the recent guidelines and PubMed database regarding surveillance, CAP, endoscopic, open, laparoscopic, and robot-assisted ureteral surgical treatment. Despite the striking results of previous studies revealing the ineffectiveness of CAP, more recent studies and their two fresh meta-analyses revealed a positive role for CAP in the contemporary management of VUR. One of the most interesting findings is the redundant rising of endoscopic correction and its final settlement to real indicated cases. Patient individualization in the contemporary management of VUR seems to be the keyword. The evidence in the literature showed a safe and effective use of laparoscopic and robot-assisted laparoscopic reimplantations. The goal of VUR treatment is to prevent the occurrence of febrile urinary tract infections and formation of scars in the renal parenchyma. The approach should be risk adapted and individualized according to current knowledge. Individual risk is influenced by the presentation age, sex, history of pyelonephritis and renal damage, grade of reflux, bladder bowel

    Full Text Available Abstract Background The total number of cardiovascular (CVD deaths accounted for almost a third of all deaths globally in 2013. Population based randomised controlled trials, managed within primary care, on CVD risk factor interventions are scarce. The aim of the study was to evaluate the effects of a health dialogue intervention in a primary care setting offered to a population at the age of 55 years, focusing on CVD risk factors. Methods The study was performed in five primary health care centres in the county of Västmanland, Sweden between April 2011 and December 2012. Men and women were randomly assigned to intervention (n = 440 and control groups (n = 440. At baseline, both groups filled in a health questionnaire and serum cholesterol, fasting plasma glucose, glycated haemoglobin (HbA1c, weight, height, waist (WC and hip circumference, waist hip ratio (WHR and systolic/diastolic blood pressure were measured. Intervention group attended a health dialogue, supported by a visualised health profile, with a possibility for further activities. Participation rates at baseline were 53% and 52% respectively. A 1-year follow-up was carried out. Results The intervention group (n = 165 showed reductions compared to the control group (n = 177 concerning body mass index (BMI (0.3 kg/m2, p = .031, WC (2.1 cm, p ≤ .001 and WHR (.002, p ≤ .001 at the 1-year follow-up. No differences between the intervention and control groups were found in other variables. Intervention group, compared to baseline, had reduced weight, BMI, WC, WHR, HbA1c, and diet, while the men in the control group had reduced their alcohol consumption. Conclusions A health dialogue intervention at the age of 55 years, conducted in ordinary primary care, showed a moderate effect on CVD risk factor levels, in terms of BMI, WC and WHR.

    The mechanisms that cause acid reflux in patients with non-erosive reflux disease (NERD), including those that determine how acid extends proximally, are not yet clear. Concurrent esophageal manometry and pH monitoring were performed for 3 h after a meal in 13 patients with NERD, 12 with mild reflux esophagitis (RE), and 13 healthy subjects (HS). Transient lower esophageal sphincter (LES) relaxation (TLESR) was the major mechanism of acid reflux in all three groups. LES pressure did not differ between the groups. At 2 cm above the LES, there were no differences between the three groups in the number of TLESR-related acid reflux episodes, rate of TLESRs and rate of acid reflux during TLESR. However, at 7 cm above the LES, the rate of acid reflux during TLESRs was significantly higher in patients with NERD (mean ± SEM 42.3 ± 4.8) than in those with mild RE (28.0 ± 3.8) and HS (10.8 ± 2.5). TLESRs are the sole motor events underlying acid reflux episodes in patients with NERD. Acid extends proximally more readily in patients with NERD than in HS and those with mild RE.

    To investigate the association between esophageal motility and acid reflux in patients with gastroesophageal reflux disease (GERD). A total of 94 patients with typical reflux symptoms such as heartburn, regurgitation and chest pain, whose score (Sc) of reflux diagnostic questionnaire (RDQ) was greater than or equal to 12 were enrolled in the study. Each participant was evaluated by upper gastrointestinal endoscopy, high resolution manometry (HRM) of esophagus and 24 h esophageal pH monitoring. The participants were divided into groups of reflux esophagitis (RE) and non-erosive reflux disease (NERD) on the basis of endoscopy findings. The 24 h esophageal pH monitoring categorized participants into physiologic reflux (pH) and pathologic reflux (pH+). The characteristics of esophageal motility and acid reflux were compared between the two groups of participants. Lower but non-significant differences (P > 0.05) were found in pressure of lower esophageal sphincter (LESP), length of lower esophageal sphincter (LESL), esophageal contraction amplitude (CA), distal contractile integral (DCI) and effective peristalsis proportion (EPP) in the participants in the RE group compared with those in the NERD group. Participants in the RE group had significantly higher prevalence of reduced LESP (63.0% vs. 31.7%, P 0.05). RE is closely associated with acid reflux and hiatus hernia. Esophageal dysmotility is more likely to appear in patients with pH+. The interaction of acid reflux and esophageal dysmotility may play a role in GERD.

    Full Text Available Tafazzin (TAZ, a transmembrane protein contributes in mitochondrial structural and functional modifications through cardiolipin remodeling. TAZ mutations are associated with several diseases, but studies on the role of TAZ protein in carcinogenesis and radiotherapy (RT response is lacking. Therefore we investigated the TAZ expression in rectal cancer, and its correlation with RT, clinicopathological and biological variables in the patients participating in a clinical trial of preoperative RT.140 rectal cancer patients were included in this study, of which 65 received RT before surgery and the rest underwent surgery alone. TAZ expression was determined by immunohistochemistry in primary cancer, distant, adjacent normal mucosa and lymph node metastasis. In-silico protein-protein interaction analysis was performed to study the predictive functional interaction of TAZ with other oncoproteins.TAZ showed stronger expression in primary cancer and lymph node metastasis compared to distant or adjacent normal mucosa in both non-RT and RT patients. Strong TAZ expression was significantly higher in stages I-III and non-mucinious cancer of non-RT patients. In RT patients, strong TAZ expression in biopsy was related to distant recurrence, independent of gender, age, stages and grade (p = 0.043, HR, 6.160, 95% CI, 1.063-35.704. In silico protein-protein interaction study demonstrated that TAZ was positively related to oncoproteins, Livin, MAC30 and FXYD-3.Strong expression of TAZ protein seems to be related to rectal cancer development and RT response, it can be a predictive biomarker of distant recurrence in patients with preoperative RT.

    Background/Aims Impedance-pH monitoring allows detailed characterization of gastroesophageal reflux and esophageal activity associated with reflux. We assessed the characteristics of nocturnal reflux and esophageal activity preceding and following reflux. Methods Impedance-pH tracings from 11 healthy subjects and 76 patients with gastroesophageal reflux disease off acid-suppressive therapy were analyzed. Characteristics of nocturnal supine reflux, time distribution and esophageal activity seen on impedance at 2 minute intervals preceding and following reflux were described. Results Patients had more nocturnal reflux events than healthy subjects (8 [4-12] vs 2 [1-5], P = 0.002), with lower proportion of weakly acidic reflux (57% [35-78] vs 80% [60-100], P = 0.044). Nocturnal reflux was mainly liquid (80%) and reached the proximal esophagus more often in patients (6% vs 0%, P = 0.047). Acid reflux predominated in the first 2 hours (66%) and weakly acidic reflux in the last 3 hours (70%) of the night. Most nocturnal reflux was preceded by aboral flows and cleared by short lasting volume clearance. In patients, prolonged chemical clearance was associated with less esophageal activity. Conclusions Nocturnal weakly acidic reflux is as common as acid reflux in patients with gastroesophageal reflux disease, and predominates later in the night. Impedance-pH can predict prolonged chemical clearance after nocturnal acid reflux. PMID:21602991

    there are many questions and little evidence regarding the diagnosis and treatment of gastroesophageal reflux disease (GERD) in children. The association between GERD and cow's milk protein allergy (CMPA), overuse of abdominal ultrasonography for the diagnosis of GERD, and excessive pharmacological treatment, especially proton-pump inhibitors (PPIs) are some aspects that need clarification. This review aimed to establish the current scientific evidence for the diagnosis and treatment of GERD in children. a search was conducted in the MEDLINE, PubMed, LILACS, SciELO, and Cochrane Library electronic databases, using the following keywords: gastroesophageal reflux; gastroesophageal reflux disease; proton-pump inhibitors; and prokinetics; in different age groups of the pediatric age range; up to May of 2013. abdominal ultrasonography should not be recommended to investigate gastroesophageal reflux (GER). Simultaneous treatment of GERD and CMPA often results in unnecessary use of medication or elimination diet. There is insufficient evidence for the prescription of prokinetics to all patients with GER/GERD. There is little evidence to support acid suppression in the first year of life, to treat nonspecific symptoms suggestive of GERD. Conservative treatment has many benefits and with low cost and no side-effects. there have been few randomized controlled trials that assessed the management of GERD in children and no examination can be considered the gold standard for GERD diagnosis. For these reasons, there are exaggerations in the diagnosis and treatment of this disease, which need to be corrected. Copyright © 2013 Sociedade Brasileira de Pediatria.

    Background: Dark skin and low exposure to sunlight increase the risk of vitamin D insufficiency in children. Objective: The aim of the study was to evaluate the amount of vitamin D needed to ascertain that most children >4 y of age attain sufficient serum 25-hydroxyvitamin D [S-25(OH)D; i.e., ≥50 nmol/L] during winter regardless of latitude and skin color. Design: In a longitudinal, double-blind, randomized, food-based intervention study, 5- to 7-y-old children from northern (63°N) and southern (55°N) Sweden with fair ( n = 108) and dark ( n = 98) skin were included. Children, stratified by skin color by using Fitzpatrick's definition, were randomly assigned to receive milk-based vitamin D 3 supplements that provided 2 (placebo), 10, or 25 μg/d during 3 winter months. Results: Mean daily vitamin D intake increased from 6 to 17 μg and 26 μg in the intervention groups supplemented with 10 and 25 μg, respectively. In the intention-to-treat analysis, 90.2% (95% CI: 81.1%, 99.3%) of fair-skinned children randomly assigned to supplementation of 10 μg/d attained sufficient concentrations, whereas 25 μg/d was needed in dark-skinned children to reach sufficiency in 95.1% (95% CI: 88.5%, 100%). In children adherent to the study product, 97% (95% CI: 91.3%, 100%) and 87.9% (95% CI: 76.8%, 99%) of fair- and dark-skinned children, respectively, achieved sufficient concentrations if supplemented with 10 μg/d. By using 95% prediction intervals for 30 and 50 nmol S-25(OH)D/L, intakes of 6 and 20 μg/d are required in fair-skinned children, whereas 14 and 28 μg/d are required in children with dark skin. Conclusion: Children with fair and dark skin require vitamin D intakes of 20 and 28 μg/d, respectively, to maintain S-25(OH)D ≥50 nmol/L, whereas intakes of 6 and 14 μg/d, respectively, are required to maintain concentrations ≥30 nmol/L during winter.

    Five patients initially presenting with symptomatic gastro-oesophageal reflux, proven by radiology or pH monitoring, subsequently developed achalasia, confirmed by radiology and manometry, after an interval of 2-10 years. During this period dysphagia, present as a mild and intermittent symptom accompanying the initial reflux in 3 of the 5, became severe and resulted in oesophageal stasis of food in all. Three of the 5 had a demonstrable hiatal hernia. In none was reflux a troublesome symptom after Rider-Moeller dilatation or cardiomyotomy undertaken for the achalasia. Gastro-oesophageal reflux does not protect against the subsequent development of achalasia. It is suggested that the autonomic damage eventually leading to achalasia may in its initial phases cause gastro-oesophageal reflux. Images Figure 1. A Figure 1. B Figure 2. PMID:3950898

    Fluoroscopic esophagography is a widely available, safe, and inexpensive test for detecting gastroesophageal reflux disease. In this article, we review the technique for performing a high-quality esophagram, including upright, double-contrast views of the esophagus and cardia with high-density barium; prone, single-contrast views of the esophagus with low-density barium; and evaluation of gastroesophageal reflux. We then discuss the radiographic findings associated with gastroesophageal reflux disease, including esophageal dysmotility, reflux esophagitis, peptic strictures, and Barrett's esophagus. Finally, we consider the differential diagnosis for the various radiographic findings associated with this condition. When carefully performed and interpreted, the esophagram is a useful test for evaluating gastroesophageal reflux disease and its complications.

  7. Reflux Revisited: Advancing the Role of Pepsin

    Directory of Open Access Journals (Sweden)

    Karna Dev Bardhan

    2012-01-01

    Full Text Available Gastroesophageal reflux disease is mediated principally by acid. Today, we recognise reflux reaches beyond the esophagus, where pepsin, not acid, causes damage. Extraesophageal reflux occurs both as liquid and probably aerosol, the latter with a further reach. Pepsin is stable up to pH 7 and regains activity after reacidification. The enzyme adheres to laryngeal cells, depletes its defences, and causes further damage internally after its endocytosis. Extraesophageal reflux can today be detected by recognising pharyngeal acidification using a miniaturised pH probe and by the identification of pepsin in saliva and in exhaled breath condensate by a rapid, sensitive, and specific immunoassay. Proton pump inhibitors do not help the majority with extraesophageal reflux but specifically formulated alginates, which sieve pepsin, give benefit. These new insights may lead to the development of novel drugs that dramatically reduce pepsinogen secretion, block the effects of adherent pepsin, and give corresponding clinical benefit.

    Otolaryngological manifestations of acid reflux include a wide range of pharyngeal and laryngeal symptoms; and the constellation of symptoms has been called laryngopharyngeal reflux. This is a prospective study in a cohort of patients with various throat symptoms suggestive of laryngopharyngeal reflux (LPR) who underwent flexible oesophago-gastroscopy, as a principal investigation. The aims were to look at the most reliable symptom(s) and sign(s), the diagnostic role of flexible oesophago-gastroscopy and the treatment response in these patients. The endoscopy score of 0 to 3 was based on endoscopic findings and the treatment response was measured from 0 to 100 per cent improvement of symptoms, as described by the patients. There were a total of 303 patients, 174 females and 129 males with ages ranging from 19 to 88 years. Seventy-five per cent had had symptoms for more than a year. Fifteen per cent were smokers. Globus, voice change, sore throat, dysphagia and cough were the predominant symptoms. Most patients, however, presented with a complex of various other secondary symptoms. The endoscopic findings were abnormal in 98 per cent of patients. Apart from the finding of non-specific hyperaemia, usually of the posterior larynx (13 per cent), lesions of the larynx and vocal folds were surprisingly uncommon. Proton pump inhibitors (PPI) were prescribed in 90 per cent of patients. A total of 233 (76.8 per cent) responded to treatment. The improvement of symptoms ranged from 25 per cent in 36 (23 per cent), 50 per cent in 60 (20 per cent), 75 per cent in 59 (19 per cent) and 100 per cent in 78 (26 per cent) patients. Accumulative analysis of variance showed a significant difference between treatment responders and non-responders (p <0.04). In a logistic regression model patients with globus, voice change and gastric prolapse were more likely to respond to treatment (p <0.04). It can be concluded that voice change, sore throat, globus and cough choking are the most

    Current imaging modalities such as magnetic resonance imaging and computed tomography provide anatomic resolution far beyond that achievable with the current methods of scintigraphic imaging. Consequently, the strength of nuclear medicine has shifted and now lies in its ability to provide physiologic data noninvasively and simply. This ability is well illustrated by the scintigraphic techniques developed for evaluation of the alimentary tract. Studies of esophageal transit, gastroesophageal reflux, and gastric emptying are now widely available. Evaluation of small and large intestinal transit have also been investigated. These techniques are discussed in the present chapter

    Gastroesophageal reflux (GER) may be defined as a dysfunction of the distal esophagus causing return of gastric contents into the esophagus. GER is a rather common problem during infancy, with an incidence estimated as 1 in 500 infants. Several methods are available to diagnose and quantitate GER. These include fluoroscopy after barium feedings, in conjunction with an upper gastrointestinal series; esophageal manometry; endoscopy; pH probe monitoring, in conjunction with a Tuttle Test; and extended pH probe evaluation for a 24-h period. Gastroesophageal scintigraphy has been advocated as an alternative noninvasive study requiring no sedation. Scintigraphy offers the advantages of prolonged observation, high sensitivity, and low radiation exposure

    Twice-daily dosing of proton pump inhibitor (PPI), the standard therapy for gastro-oesophageal reflux disease (GERD), is an effective therapy for GERD in SSc. The aim of this study was to compare the efficacy of omeprazole in combination with domperidone vs in combination with algycon in reducing the severity and frequency of reflux symptoms of PPI partial response (PPI-PR) GERD in SSc. Adult SSc patients having PPI-PR GERD were randomly assigned to receive domperidone plus algycon placebo or algycon plus domperidone placebo in a 1:1 ratio plus omeprazole for 4 weeks. The assessment included severity of symptom grading by visual analogue scale, frequency of symptoms by frequency scale for symptoms of GERD and quality of life (QoL) by EuroQol five-dimensions questionnaire scoring. One hundred and forty-eight SSc-GERD patients were enrolled, of whom 88 had PPI-PR. Eighty cases were randomized for either domperidone (n = 38) or algycon (n = 37) therapy. The majority in both groups had the diffuse SSc subset. At the end of the study, no significant difference in symptom grading was found between groups. After treatment and compared with baseline, the severity of symptoms, frequency scale for symptoms of GERD and QoL significantly improved in both groups. Five (13.2%) and 8 (21.6%) respective cases in the domperidone and algycon groups did not respond. The prevalence of PPI-PR GERD is common. Domperidone and algycon are equally effective treatments in combination with omeprazole. However, ∼17% of patients were non-responsive, so the effectiveness of domperidone, algycon and PPI combination therapy should be further investigated. https://clinicaltrials.gov (NCT01878526). © The Author 2016.

    Vesicoureteral reflux (VUR) is frequently found after transplantation, but its impact on graft function, urine tract infection, and graft loss remains uncertain. Therefore our objective was to evaluate the effects of VUR on the outcome of renal transplantation. We included 1008 adult renal transplant recipients of whom a 1-week posttransplant voiding cystourethrogram was available. Study end points included occurrence of bacteriuria, renal function, and graft survival. In total, 106 (10.5%) of 1008 graft recipients had a diagnosis of VUR on voiding cystography. The incidence of bacteriuria was comparable in the reflux and nonreflux group (17% vs 17.4%, P = .91). There was no significant difference in renal function at 3 months and 1 year in patients with and without VUR. One- and 5-year graft survival in patients with VUR was 85.8% and 82.1% compared to 87.3% and 83.0% in patients without VUR ( P = .68 and P = .80). Posttransplant VUR has no correlations with early bacteriuria, renal function, and graft survival.

    During the preschool years, children develop abilities and skills in areas crucial for later success in life. These abilities include language, executive functions, attention, and socioemotional skills. The pedagogical methods used in preschools hold the potential to enhance these abilities, but our knowledge of which pedagogical practices aid which abilities, and for which children, is limited. The aim of this paper is to describe an intervention study designed to evaluate and compare two pedagogical methodologies in terms of their effect on the above-mentioned skills in Swedish preschool children. The study is a randomized control trial (RCT) where two pedagogical methodologies were tested to evaluate how they enhanced children's language, executive functions and attention, socioemotional skills, and early maths skills during an intensive 6-week intervention. Eighteen preschools including 28 units and 432 children were enrolled in a municipality close to Stockholm, Sweden. The children were between 4;0 and 6;0 years old and each preschool unit was randomly assigned to either of the interventions or to the control group. Background information on all children was collected via questionnaires completed by parents and preschools. Pre- and post-intervention testing consisted of a test battery including tests on language, executive functions, selective auditive attention, socioemotional skills and early maths skills. The interventions consisted of 6 weeks of intensive practice of either a socioemotional and material learning paradigm (SEMLA), for which group-based activities and interactional structures were the main focus, or an individual, digitally implemented attention and math training paradigm, which also included a set of self-regulation practices (DIL). All preschools were evaluated with the ECERS-3. If this intervention study shows evidence of a difference between group-based learning paradigms and individual training of specific skills in terms of

    After the introduction of a law prohibiting the start-up of any new nuclear power plant until the utility had shown that the waste produced by the plant could be taken care of in an absolutely safe way, the Swedish nuclear utilities in December 1976 embarked on the Nuclear Fuel Safety Project, which in November 1977 presented a first report, Handling of Spent Nuclear Fuel and Final Storage of Vitrified Waste (KBS-I), and in November 1978 a second report, Handling and Final Storage of Unreprocessed Spent Nuclear Fuel (KBS II). These summary reports were supported by 120 technical reports prepared by 450 experts. The project engaged 70 private and governmental institutions at a total cost of US $15 million. The KBS-I and KBS-II reports are summarized in this document, as are also continued waste research efforts carried out by KBS, SKBF, PRAV, ASEA and other Swedish organizations. The KBS reports describe all steps (except reprocessing) in handling chain from removal from a reactor of spent fuel elements until their radioactive waste products are finally disposed of, in canisters, in an underground granite depository. The KBS concept relies on engineered multibarrier systems in combination with final storage in thoroughly investigated stable geologic formations. This report also briefly describes other activities carried out by the nuclear industry, namely, the construction of a central storage facility for spent fuel elements (to be in operation by 1985), a repository for reactor waste (to be in operation by 1988), and an intermediate storage facility for vitrified high-level waste (to be in operation by 1990).

    Esophageal motility abnormalities are among the main factors implicated in the pathogenesis of gastroesophageal reflux disease. The recent introduction in clinical and research practice of novel esophageal testing has markedly improved our understanding of the mechanisms contributing to the development of gastroesophageal reflux disease, allowing a better management of patients with this disorder. In this context, the present article intends to provide an overview of the current literature about esophageal motility dysfunctions in patients with gastroesophageal reflux disease. Esophageal manometry, by recording intraluminal pressure, represents the gold standard to diagnose esophageal motility abnormalities. In particular, using novel techniques, such as high resolution manometry with or without concurrent intraluminal impedance monitoring, transient lower esophageal sphincter (LES) relaxations, hypotensive LES, ineffective esophageal peristalsis and bolus transit abnormalities have been better defined and strongly implicated in gastroesophageal reflux disease development. Overall, recent findings suggest that esophageal motility abnormalities are increasingly prevalent with increasing severity of reflux disease, from non-erosive reflux disease to erosive reflux disease and Barrett’s esophagus. Characterizing esophageal dysmotility among different subgroups of patients with reflux disease may represent a fundamental approach to properly diagnose these patients and, thus, to set up the best therapeutic management. Currently, surgery represents the only reliable way to restore the esophagogastric junction integrity and to reduce transient LES relaxations that are considered to be the predominant mechanism by which gastric contents can enter the esophagus. On that ground, more in depth future studies assessing the pathogenetic role of dysmotility in patients with reflux disease are warranted. PMID:24868489

    Gastroesophageal reflux disease is a chronic disease with a high incidence worldwide. The various symptoms have substantial impact on the quality of life of affected individuals. A long-term self-management program can increase the ability of patients to make behavioral changes, and health outcomes can improve as a consequence. This study's aim was to evaluate the effectiveness of a self-management program for gastroesophageal reflux disease. A total of 115 patients with gastroesophageal reflux disease were allocated to the experimental group and the control group. The former received self-management intervention along with conventional drug therapy, whereas the latter received standard outpatient care and conventional drug therapy. After the clinical trial, the control group also received the same self-management intervention. The levels of self-management behaviors, self-efficacy, gastroesophageal reflux disease symptoms, and psychological condition were compared. Those in the experimental group demonstrated significantly higher self-efficacy for managing their illness, showed positive changes in self-management behaviors, and had comparatively better remission of symptoms and improvement in psychological distress. The program helped patients with gastroesophageal reflux disease self-manage their illness as possible.

    2017-09-01

    A magnetic implant for the treatment of gastroesophageal reflux disease (GERD) was Food and Drug Administration-approved in 2012 and has been extensively evaluated. The device is a ring of magnets that are placed around the gastroesophageal junction, augmenting the native lower esophageal sphincter and preventing reflux yet preserving lower esophageal sphincter physiologic function and allowing belching and vomiting. Magnetic force is advantageous, being permanent and precise, and forces between magnets decrease with esophageal displacement. Multiple patient cohorts have been studied using the magnetic device, and trials establish consistent, long-term improvement in pH data, GERD symptom scores, and proton-pump inhibitor use. A 5-year Food and Drug Administration trial demonstrated that most patients achieved normal pH scores, 85% stopped proton-pump inhibitors, and GERD health-related quality of life symptom scores improved from 27 to 4 at 5 years. Seven studies have compared magnetic augmentation with laparoscopic Nissen fundoplication and demonstrated that the magnetic device achieved comparable efficacy with regard to proton-pump inhibitor cessation, GERD symptom score improvement, and heartburn and regurgitation scores. However, to date there have been no randomized, controlled trials comparing the 2 techniques, and the study cohorts are not necessarily comparable regarding hiatal hernia size, severity of reflux, body mass index scores, or esophagitis scores. Dysphagia incidence was similar in both groups. Reoperation rates and safety profiles were also comparable, but the magnetic device demonstrated significant beneficial differences in allowing belching and vomiting. The magnetic device is safe, with the main adverse event being dysphagia with an approximate 3%-5% chronic incidence. Device removals in clinical trials have been between 0% and 7% and were uneventful. There have been no erosions, perforations, or infections in FDA clinical trials

    Non-erosive reflux disease (NERD) patients are more sensitive than erosive esophagitis patients to weakly acidic reflux and to the presence of gas in the refluxate. Intra-esophageal acid perfusion sensitizes esophageal receptors to mechanical and chemical stimuli. To establish whether acid sensitization plays a role in the perception of weakly acidic and mixed reflux episodes, 29 NERD patients, responders and 14 non-responders to proton pump inhibitors (PPIs), underwent pH-impedance monitoring. Non-responders repeated the study while on PPIs. To assess the effect of acid exposure on symptom perception, the time period with pH below 4 was measured in 15- and 30-minute time-windows preceding the onset of each reflux episode. Considering weakly acidic and mixed refluxes, both in responder and non-responder patients (off PPIs), the symptomatic refluxes were preceded by a significantly higher cumulative acid exposure than the asymptomatic refluxes. In all patients, following acid reflux, the percentage of symptomatic weakly acidic reflux episodes was significantly higher than that of asymptomatic refluxes. Non-responder patients, off-treatment, were characterized by a lower proportion of weakly acidic reflux and mixed reflux episodes. In the non-responder patients on PPI, only mixed and weakly symptomatic reflux episodes were preceded by a higher cumulative acid exposure. In NERD patients, spontaneous acid reflux enhances subsequent reflux perception, regardless of acidity or liquid/mixed composition of episodes; in non-responder patients on PPIs, only the perception of mixed and weakly acidic reflux episodes seems to be mediated by a preceding acid exposure. © 2013 John Wiley & Sons Ltd.

  4. Reflux esophagitis and gastroesophageal reflux disease: a cross-sectional study of gastroesophageal reflux disease patients by age group

    Full Text Available The purpose of this study was to explore the relationship between the intensity of acid reflux and severity of esophageal tissue damage in a cross-sectional study of patients with gastroesophageal reflux disease (GERD. Seventy-eight patients with were selected in accordance with the strict 24-hour ambulatory esophageal pHmetry (24h-pHM criteria and distributed into three age groups: Group A: 14 - 24 years of age. Group B: 25 - 54; and Group C: 55 - 64. The 24h-pHM was carried out in accordance with DeMeester standardization, and the Savary-Miller classification for the diagnosis of reflux esophagitis was used. The groups were similar in 24h-pHM parameters (p > 0.05, having above normal values. For the study group as a whole, there was no correlation between age group and intensity of acid reflux, and there was no correlation between intensity of acid reflux and severity of esophageal tissue damage. However, when the same patients were sub-grouped in accordance with the depth of their epithelial injury and then distributed into age groups, there was a significant difference in esophagitis without epithelial discontinuity. Younger patients had less epithelial damage than older patients. Additionally, although there was a significant progression from the least severe to the moderate stages of epithelial damage among the age groups, there was no apparent difference among the age groups in the distribution between the moderate stages and most severe stages. The findings support the conclusion that the protective response of individuals to acid reflux varies widely. Continued aggression by acid reflux appears to lead to the exhaustion of individual mechanisms of epithelial protection in some patients, but not others, regardless of age or duration of the disease. Therefore, the diagnosis and follow-up of GERD should include both measurements of the quantity of refluxed acid and an assessment of the damage to the esophageal epithelium.

    A more prominent role for the youth healthcare physician: Youth Healthcare physicians reflect on the Dutch Paediatric Association (NVK) guideline entitled 'Gastro-oesophageal reflux (disease) in children aged 0-18 years'. This guideline states that medicinal treatment is given to these children too often. Dutch Youth Healthcare physicians see a large number of children with gastro-oesophageal reflux, with or without additional symptoms. The most common symptoms (crying and diminished weight gain) might be present even in the absence of reflux. Parents should be given advice and support when they are worried about reflux, crying or low weight gain. A lower weight gain curve on the growth chart is normal in breastfed children, and crying might be due to factors such as lack of routine or stimulus reduction. Overfeeding might also be the cause. Parents should be supported and followed up, with or without treatment, as necessary. Youth Healthcare professionals could perform this task.

    Scintigraphic techniques are the only quantitative methods for the evaluation of esophageal transit and gastroesophageal reflux. By comparison, other techniques are not quantitative and are either indirect, inconvenient, or less sensitive. Methods, such as perfusion techniques, which measure flow, require the introduction of a tube assembly into the gastrointestinal tract with the possible introduction of artifacts into the measurements due to the indwelling tubes. Earlier authors using radionuclide markers, introduced a method for measuring gastric emptying which was both tubeless and quantitative in comparison to other techniques. More recently, a number of scintigraphic methods have been introduced for the quantitation of esophageal transit and clearance, the detection and quantitation of gastroesophageal reflux, the measurement of gastric emptying using a mixed solid-liquid meal, and the quantitation of enterogastric reflux. This chapter reviews current techniques for the evaluation of esophageal transit and gastroesophageal reflux

    Thirty-six children with urinary tract infection aged 6 months to 14 years (mean age 4 1/2 years) were studied sequentially using direct radionuclide (RNC) and conventional voiding cystourethrography (VCU). Vesicoureteral reflux (VUR) was detected equally well by both methods. Twenty-seven refluxing ureters were found by RNC, 23 by VCU and 22 by both methods. Radiologic grade of reflux may be determined approximately with the isotope technique from the volume of regurgitating urine und duration of reflux, at a much decreased radiation exposure. Residual urine was also measured by RNC and found to be higher in children with VUR. RNC is a reliable method for detecting and grading VUR and should effectively replace VCU as the follow-up examination of choice. (orig.)

    Mechanisms of gastro-oesophageal reflux were studied by oesophageal manometry and pH monitoring in 33 children: nine controls, 15 with gastro-oesophageal reflux alone, and nine with reflux oesophagitis. A total of 122 episodes of reflux were analysed in detail: 82 (67%) were synchronous with swallowing and 40 (33%) asynchronous. Infants with trivial symptoms had gastro-oesophageal reflux synchronous with swallowing, whereas those with serious symptoms had slower acid clearance and asynchronous reflux. There were significant differences in lower oesophageal sphincter pressure and amplitude of oesophageal contractions between controls and patients with both gastro-oesophageal reflux and reflux oesophagitis. In reflux oesophagitis there was a decrease in lower oesophageal sphincter pressure and the contractions had a bizarre waveform suggesting a neuropathic process. PMID:3202640

    Gastroesophageal reflux disease is a worldwide prevalent condition that exhibits a large variety of signs and symptoms of esophageal or extra-esophageal nature and can be related to the esophagic adenocarcinoma. In the last few years, greater importance has been given to the influence of physical exercises on it. Some recent investigations, though showing conflicting results, point to an exacerbation of gastroesophageal reflux during physical exercises. To evaluate the influence of physical activities in patients presenting with erosive and non erosive disease by ergometric stress testing and influence of the lower esophageal sphincter tonus and body mass index during this situation. Twenty-nine patients with erosive disease (group I) and 10 patients with non-erosive disease (group II) were prospectively evaluated. All the patients were submitted to clinical evaluation, followed by upper digestive endoscopy, manometry and 24 h esophageal pH monitoring. An ergometric testing was performed 1 h before removing the esophageal pH probe. During the ergometric stress testing, the following variables were analyzed: test efficacy, maximum oxygen uptake, acid reflux duration, gastroesophageal reflux symptoms, influence of the lower esophageal sphincter tonus and influence of body mass index in the occurrence of gastroesophageal reflux during these physical stress. Maximum oxigen consumption or VO 2 max, showed significant correlation when it was 70% or higher only in the erosive disease group, evaluating the patients with or without acid reflux during the ergometric testing (p=0,032). The other considered variables didn't show significant correlations between gastroesophageal reflux and physical activity (p>0,05). 1) Highly intensive physical activity can predispose the occurrence of gastroesophageal reflux episodes in gastroesophageal reflux disease patients with erosive disease; 2) light or short sessions of physical activity have no influence on reflux, regardless of body

    Acid changes in gastroesophageal reflux with vary component in the food have less been studied, especially carbohydrate. We plan to clarify the effect of different carbohydrate density on low esophageal acid and reflux symptoms of patients with gastroesophgeal reflux disease. Twelve patients (52 ± 12 years old; five female) with gastroesophageal reflux disease were recruited for the prospective crossover study. Each patient was invited for panendoscope, manometry and 24 h pH monitor. The two formulated liquid meal, test meal A: 500 ml liquid meal (containing 84.8 g carbohydrate) and B: same volume liquid meal (but 178.8 g carbohydrate) were randomized supplied as lunch or dinner. Reflux symptoms were recorded. There are significant statistic differences in more Johnson-DeMeester score (p = 0.019), total reflux time (%) (p = 0.028), number of reflux periods (p = 0.026) and longest reflux (p = 0.015) after high carbohydrate diet than low carbohydrate. Total reflux time and number of long reflux periods more than 5 min are significant more after high carbohydrate diet. More acid reflux symptoms are found after high carbohydrate diet. High carbohydrate diet could induce more acid reflux in low esophagus and more reflux symptoms in patients with gastroesophageal reflux disease. Copyright © 2018. Published by Elsevier B.V.

I am also since some years a member of the local ethics advisory board in a mostly rural area serving 180.000 people. From that position I advise on what types of local project applications will have to be sent further to the regional ethics committee, REPN in Sweden. With that background I will try to give a brief Swedish perspective on research ethics reviews in general and regarding CGT (classic grounded theory studies using qualitative data in particular.The most famous Swedish example of unethical research is the 1947-1951 Vipeholm sugar trial (Krasse, 2001. Several hundred intellectually and mentally challenged persons at the Vipeholm institution were for years given an excess amount of sugar, mostly in the shape of candy. This resulted in caries that totally ruined the teeth of 50 persons. Of course participants did not give informed consent. Yet, at the time the research was not considered unethical. At least there was no debate about it.

    The mechanisms underlying symptoms in non-erosive reflux disease (NERD) remain to be elucidated. Non-erosive reflux disease patients appear to be more sensitive to intraluminal stimula than erosive patients, the proximal oesophagus being the most sensitive. In order to assess regional oesophageal changes in reflux acidity and sensitivity to reflux, according either to the acidity or the composition of the refluxate, combined multiple pH and multiple pH-impedance (pH-MII) was performed in 16 NERD patients. According to multiple pH-metry, 29% and 12% of reflux events reached the middle and proximal oesophagus respectively, and 35% and 19% according to conventional pH-MII (P acid reflux became weakly acidic at the proximal oesophagus. In all patients, the frequency of symptomatic refluxes, both acid and weakly acidic, was significantly higher at the proximal, compared with distal oesophagus (25 +/- 8%vs 11 +/- 2% for acid reflux and 27 +/- 8%vs 8 +/- 2% for weakly acidic reflux; P reflux. As approximately 30% of acid reflux becomes weakly acidic along the oesophageal body, to better characterize proximal reflux, in clinical practice, combined proximal pH-impedance monitoring should be used. In NERD patients, the proximal oesophagus seems to be more sensitive to both acid and weakly acidic reflux.

    An investigation to detect food-stimulated gastro-oesophageal (GE) reflux was carried out in 54 consecutive fasting patients, 35 of whom experienced reflux while 19 did not. All patients then received a standard meal (566 kcal), and the investigation was repeated 1 h afterward. Of the 35 with GE reflux in the fasting state, 33 also had GE reflux in the postprandial state, and 17 of the 19 patients with no GE reflux while fasting also had none in the postprandial state. It is concluded that the radiological method can identify most patients in whom food-stimulated GE reflux could be of clinical significance. (orig.).

    This study is to determine the association of ambulatory pH monitoring (24hr pH) with symptoms of gastroesophageal reflux and its other investigations. The clinical and epidemiological profiles of subjects referred for reflux disorders are also studied. Symptoms or group of symptoms, profiles and prior investigations of 1259 consecutive pediatric subjects (with 1332 24hr pH studies performed) referred for evaluation of reflux disorders between 1988 and 2012 were retrospectively studied. Chi-square or fisher exact test was used for hypothesis testing, student t-test for the comparison of means and the Wilcoxon rank-sum test for comparing medians of continuous variables. Gastroesophageal reflux disease (GERD), defined as reflux causing major symptoms and complications, was diagnosed in 57.5% subjects of the total sample. Forty-three percent were girls and 56.7% were boys. The most common age group was between 4 months and 2 years (51.2%). Vomiting (64.4%) and irritability (74%) were the most common symptoms with the neurological conditions (23.2%) being the most frequent underlying condition. The parameters used in 24hr pH were significantly higher in those diagnosed with GERD (P reflux disorders. 24hr pH is reliable and should be considered routine in reflux disorders, as it identifies patients with pathologic reflux and avoids a needless surgery. © 2016 International Society for Diseases of the Esophagus.

    To analyse the association between 24-hour multichannel intraluminal impedance-pH (24-h MII-pH) parameters and each item of the reflux finding score (RFS) to determine whether the laryngoscopic findings of the RFS could reflect the characteristics of reflux in patients with laryngopharyngeal reflux (LPR). Prospective cohort study. Tertiary care referral medical centre. Patients complaining of LPR symptoms were evaluated via a 24-hour MII-pH. Among them, 99 patients whose LPR was confirmed via 24-hour MII-pH were enrolled in this study. Correlations between RFS ratings and 24-hour MII-pH parameters were evaluated and compared between patients with or without each laryngoscopic finding used in the RFS. Subglottic oedema had a statistically significant positive correlation with number of non-acid LPR and non-acid full column reflux events. Ventricular obliteration and posterior commissure hypertrophy showed a significant correlation with non-acid exposure time and total reflux exposure time. We also found a significant correlation between granuloma/granulation score and number of acid LPR events. The numbers of non-acid LPR and full column reflux events in patients with subglottic oedema were significantly higher than those without subglottic oedema. Among the laryngoscopic findings used in the RFS, subglottic oedema is specific for non-acid reflux episodes, and granuloma/granulation is specific for acid reflux episodes. © 2017 John Wiley & Sons Ltd.

The clinical picture of gastroesophageal reflux disease is usually composed by heartburn and regurgitation (typical manifestations. Atypical manifestations (vocal disturbances and asthma may also be complaint. OBJECTIVE: To analyse the clinical, endoscopic, manometric and pHmetric aspects of patients suffering from gastroesophageal reflux disease associated with vocal disturbances. METHODS: Fifty patients with gastroesophageal reflux disease were studied, including 25 with vocal disturbances (group 1 - G1 and 25 without these symptoms (group 2 - G2. All patients were submitted to endoscopy, manometry and esophageal pHmetry (2 probes. The group 1 patients were submitted to videolaryngoscopy. RESULTS: Endoscopic findings: non-erosive reflux disease was observed in 95% of G1 patients and 88% of G2. Videolaryngoscopy: vocal fold congestion, asymmetry, nodules and polyps were observed in G1 patients. Manometric findings: pressure in the lower esophageal sphincter (mm Hg: 11.6 ± 5.2 in G1 and 14.0 ± 6.2 in G2 (P = 0.14; pressure in the upper esophageal sphincter (mm Hg: 58.4 ± 15.9 in G1 and 69.5 ± 30.7 in the controls. pHmetric findings: De Meester index: 34.0 ± 20.9 in G1 and 15.4 ± 9.4 in G2 (P<0.001; number of reflux episodes in distal probe: 43.0 ± 20.4 in G1 and 26.4 ± 17.2 in G2 (P = 0.003; percentage of time with esophageal pH value lower than 4 units (distal sensor: 9.0% ± 6.4% in G1 and 3.4% ± 2.1% in G2 (P<0.001; number of reflux episodes in proximal probe: 7.5 ± 10.9 in G1 and 5.3 ± 5.7 in G2 (P = 0.38; percentage of time with esophageal pH values lower than 4 units (Proximal probe: 1.2 ± 2.7 in G1 and 0.5 ± 0.7 in G2 (P = 0.21.

    Alginates form a raft above the gastric contents, which may suppress gastro-oesophageal reflux; however, inconsistent effects have been reported in mechanistic and clinical studies. To visualise reflux suppression by an alginate-antacid [Gaviscon Advance (GA), Reckitt Benckiser, UK] compared with a nonraft-forming antacid using magnetic resonance imaging (MRI), and to determine the feasibility of pH-impedance monitoring for assessment of reflux suppression by alginates. Two studies were performed: (i) GA and antacid (Alucol, Wander Ltd, Switzerland) were visualised in the stomach after ingestion in 12 healthy volunteers over 30 min after a meal by MRI, with reflux events documented by manometry. (ii) A randomised controlled, double-blind cross-over trial of post-prandial reflux suppression documented by pH-impedance in 20 patients randomised to GA or antacid (Milk of Magnesia; Boots, UK) after two meals taken 24 h apart. MRI visualized a "mass" of GA form at the oesophago-gastric junction (OGJ); simple antacid sank to the distal stomach. The number of post-prandial common cavity reflux events was less with GA than antacid [median 2 (0-5) vs. 5 (1-11); P < 0.035]. Distal reflux events and acid exposure measured by pH-impedance were similar after GA and antacid. There was a trend to reduced proximal reflux events with GA compared with antacid [10.5 (8.9) vs. 13.9 (8.3); P = 0.070]. Gaviscon Advance forms a 'mass' close to the OGJ and significantly suppresses reflux compared with a nonraft-forming antacid. Standard pH-impedance monitoring is suitable for clinical studies of GA in gastro-oesophageal reflux disease patients where proximal reflux is the primary outcome. © 2013 Blackwell Publishing Ltd.

    Patients with symptoms compatible with gastroesophageal reflux (GER) disease and asymptomatic controls were evaluated three times for GER by gastroesophageal reflux scintigraphy (GES) at intervals ranging from 6 h to 15 days and after various periods of fasting. Similarly, in patients and controls, pH monitoring at the distal esophagus was conducted three times by applying the standard reflux test (SART) at intervals ranging from 4 h to 3 days after different fasting periods. In 18 of 19 patients and 14 of 15 controls the results of SART were indentical on all three occations. A similar agreement was found for GES in 23 of 25 patients and 20 of 21 controls. The reproducibility of the induced type of reflux after ingestion of acidified organic juce was significantly better than that of the spontaneous types or the induced type of reflux after ingestion of saline. It is concluded that the reproducibility of GES and SART is similatly good

    Full Text Available Obstetric thromboprophylaxis is difficult. Since 10 years Swedish obstetricians have used a combined risk estimation model and recommendations concerning to whom, at what dose, when, and for how long thromboprophylaxis is to be administrated based on a weighted risk score. In this paper we describe the background and validation of the Swedish guidelines for obstetric thromboprophylaxis in women with moderate-high risk of VTE, that is, at similar or higher risk as the antepartum risk among women with history of thrombosis. The risk score is based on major risk factors (i.e., 5-fold increased risk of thromboembolism. We present data on the efficacy of the model, the cost-effectiveness, and the lifestyle advice that is given. We believe that the Swedish guidelines for obstetric thromboprophylaxis aid clinicians in providing women at increased risk of VTE with effective and appropriate thromboprophylaxis, thus avoiding both over- and under-treatment.

    Full Text Available CONTEXT: Although the high incidence of gastroesophageal reflux disease (GERD in the population, there is much controversy in this topic, especially in the surgical treatment. The decision to use of a total or partial fundoplication in the treatment of GERD is still a challenge to many surgeons because the few evidence found in the literature. OBJECTIVE: To bring more clear evidence in the comparison between total and partial fundoplication. DATA SOURCES: A systematic review of the literature and metaanalysis with randomized controlled trials accessed from MEDLINE, LILACS, Cochrane Controlled Trials Database was done. The outcomes remarked were: dysphagia, inability to belch, bloating, recurrence of acid reflux, heartburn and esophagitis. For data analysis the odds ratio was used with corresponding 95% confidence interval. Statistical heterogeneity in the results of the metaanalysis was assessed by calculating a test of heterogeneity. The software Review Manager 5 (Cochrane Collaboration was utilized for the data gathered and the statistical analysis. Sensitive analysis was applied using only trials that included follow-up over 2 years. RESULTS: Ten trials were included with 1003 patients: 502 to total fundoplication group and 501 to partial fundoplication group. The outcomes dysphagia and inability to belch had statistical significant difference (P = 0.00001 in favor of partial fundoplication. There was not statistical difference in outcomes related with treatment failure. There were no heterogeneity in the outcomes dysphagia and recurrence of the acid reflux. CONCLUSION: The partial fundoplication has lower incidence of obstructive side effects.

    The spectrophotometric probe, which uses bilirubin as a marker for the detection of duodenoesophagic reflux is subject to interference from strongly colored foods, which can cause erroneously high bilirubin absorbance readings. To overcome this problem it is necessary to ingest a diet that is free from such substances. To test the absorbance of 48 different food substances in an in vitro environment. Dry foods were blended with water or milk and non-dry solid foods were blended undiluted. It was utilized the proper calibration recipient to test them. The absorbance of weakly colored foods was usually lesser than the commonly accepted threshold of 0.14, and the absorbance of strongly colored foods was usually above this. Thirty-two from the 48 substances tested are suitable when the absorbance threshold is set at 0.14, but scrambled eggs, lacteous flour mush, green beans, beetroot, carrot, chayote, squash, "baroa" potato, boiled corn, orange, cashew, purple grape, avocado, mango, papaya and peach can alter the results and must be avoided. From the foods evaluated, enough are suitable at the 0.14 threshold to enable a suitable diet to be constructed for most patients during Bilitec studies.

  14. Bladder Dysfunction and Vesicoureteral Reflux

    Full Text Available In this overview the influence of functional bladder disturbances and of its treatment on the resolution of vesicoureteral reflux (VUR in children is discussed. Historically both bladder dysfunction entities, the overactive bladder (OAB and the dysfunctional voiding (DV, have been described in conjunction with VUR. Treatment of the dysfunction was also considered to influence spontaneous resolution in a positive way. During the last decades, however, papers have been published which could not support these results. Regarding the OAB, a prospective study with treatment of the bladder overactivity with anticholinergics, did not influence spontaneous resolution rate in children with a dysfunction including also the voiding phase, DV and DES (dysfunctional elimination syndrome, most studies indicate a negative influence on the resolution rate of VUR in children, both before and after the age for bladder control, both with and without treatment. However, a couple of uncontrolled studies indicate that there is a high short-term resolution rate after treatment with flow biofeedback. It should be emphasized that the voiding phase dysfunctions (DV and DES are more severe than the genuine filling phase dysfunction (OAB, with an increased frequency of UTI and renal damage in the former groups. To be able to answer the question if treatment of bladder dysfunction influence the resolution rate of VUR in children, randomized controlled studies must be performed.

  15. Radiologic quantitation of gastro-oesophageal reflux. Correlation between height of food stimulated gastro-oesophageal reflux and level of histologic changes in reflux oesophagitis

    Energy Technology Data Exchange (ETDEWEB)

    Christiansen, T.; Funch-Jensen, P.; Jacobsen, N.O.; Thommesen, P.

    In a prospective study, 26 patients with symptoms of reflux oesophagitis underwent a barium examination for gastro-oesophageal reflux after food stimulation, and endoscopy with biopsy from different levels of the oesophagus. Radiologic grading of the gastro-oesophageal reflux depending on the height of the reflux into the oesophagus was performed, and this was correlated to the microscopic appearance at different levels in the oesophagus. Complete agreement between the radiologic grading and the histology was found in 69 per cent of the cases, and when gastro-oesophageal reflux was demonstrated the agreement was 75 per cent. Accordingly, the results showed a good accordance between the two variants, indicating that the height of the reflux during the food stimulated test may be truly indicative of the reflux height under non-test conditions.

    Patients with peptic esophagitis or typical complaints with respect to reflux without esophagitis and control persons (n = 68) were comparatively examined for gastroesophageal reflux by means of scintigraphy (after administration of test solutions labelled with /sup 99m/Tc-DTPA or after intravenous application of /sup 99m/Tc-pertechnetate) and by means of continuous intraesophageal p/sub H/ measurement. The scintigraphic test of the reflux was successful for very few patients only with reflux disease and a reflux detectable by measuring the p/sub H/. The application of pentagastrin failed in improving the scintigraphic detection of the reflux. The cause of the unsuccessful scintigraphic evidence for the majority of the reflux patients seems to be the relatively small reflux volume.

    Gastro-oesophageal reflux disease (GORD) is a complex problem in children. Suspected respiratory manifestations of GORD, such as asthma, chronic cough and laryngitis, are commonly encountered in the paediatric practice, but continue to be entities with more questions than answers. The accuracy of diagnostic tests (ie, pH or pH-impedance monitoring, laryngoscopy, endoscopy) for patients with suspected extraoesophageal manifestations of GORD is suboptimal and therefore whether there is a causal relationship between these conditions remains largely undetermined. An empiric trial of proton pump inhibitors can help individual children with undiagnosed respiratory symptoms and suspicion of GORD, but the response to therapy is unpredictable, and in any case what may be being observed is spontaneous improvement. Furthermore, the safety of these agents has been called into question. Poor response to antireflux therapy is an important trigger to search for non-gastro-oesophageal reflux causes for patients' symptoms. Evidence for the assessment of children with suspected extraoesophageal manifestations of GORD is scanty and longitudinal studies with long-term follow-up are urgently required. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    Atrial fibrillation (AF) is the most common sustained arrhythmia and is associated with significant morbidity and mortality. Multiple conditions like hypertension, heart failure, diabetes, sleep apnoea, and obesity play a role for the initiation and perpetuation of AF. Recently, a potential association between gastroesophageal reflux disease (GERD) and AF development has been proposed due to the close anatomic vicinity of the oesophagus and the left atrium. As an understanding of the association between acid reflux disease and AF may be important in the global multimodal treatment strategy to further improve outcomes in a subset of patients with AF, we discuss potential atrial arrhythmogenic mechanisms in patients with GERD, such as gastric and subsequent systemic inflammation, impaired autonomic stimulation, mechanical irritation due to anatomical proximity of the left atrium and the oesophagus, as well as common comorbidities like obesity and sleep-disordered breathing. Data on GERD and oesophageal lesions after AF-ablation procedures will be reviewed. Treatment of GERD to avoid AF or to reduce AF burden might represent a future treatment perspective but needs to be scrutinized in prospective trials.

    2015-09-01

    Full Text Available Gastro-oesophageal reflux disease (GERD is a disorder in which reflux of stomach contents causes troublesome symptoms and/or complications and which affects health-related quality of life. It is one of the commonest disorders and appears to be increasing in incidence. The mechanisms leading to reflux are complex and multifactorial. The lower oesophageal sphincter (LES is an important part of the gastro-oesophageal barrier. Transient LES relaxations (TLESRs lead to reflux as these vagally mediated motor patterns cause relaxation of the LES and also result in oesophageal shortening and inhibition of the crural diaphragm. Heartburn and regurgitation are the characteristic symptoms of GERD. A clinical diagnosis of GERD can be made with typical symptoms. Oesophagitis is seen in a minority of patients with GERD. Lifestyle modification is widely advocated for patients with GERD. For short-term relief of symptoms of mild GERD, antacids/alginates are frequently used but they do not heal oesophagitis. Both histamine 2 receptor antagonists (H2RA and proton pump inhibitors (PPI have been shown to heal and prevent relapse of oesophagitis, although PPIs have been shown to be superior. The PPIs are the recommended first-line therapy for erosive oesophagitis and initial management of non-erosive reflux disease. Maintenance PPI therapy should be given to patients with oesophagitis, those who have recurrence of symptoms after discontinuation of medication and for those with complications of GERD.

    Gastroesophageal reflux disease is one of the most common disorders of the gastrointestinal tract. The prevalence of this disease ranges from 5% to 20% in Asia, Europe, and North America. The aim of this study was to estimate the burden of gastroesophageal reflux disease in Iran. Burden of gastroesophageal reflux disease in Iran was estimated for one year from 21 March 2006 to 20 March 2007. The definition was adjusted with ICD-code of K21. Incident-based disability-adjusted life year (DALY) was used as the unit of analysis to quantify disease burden. A simplified disease model and DisMod II software were used for modeling. The annual incidence for total population of males and females in Iran was estimated 17.72 and 28.06 per 1000, respectively. The average duration of gastroesophageal reflux disease as a chronic condition was estimated around 10 years in both sexes. Total DALYs for an average of 59 symptomatic days per year was estimated 153,554.3 (60,330.8 for males and 93,223.5 for females).   The results of this study showed that reflux imposes high burden and high financial costs on the Iranian population. The burden of this disease in Iran is more similar to that of European countries rather than Asian countries. It is recommended to consider the disease as a public health problem and make decisions and public health plans to reduce the burden and financial costs of the disease in Iran.

    Follicular tracheitis (also known as tracheal cobblestoning) is an entity that is poorly described and of unclear significance. The objective of this study was to better define follicular tracheitis and determine the association between the clinical finding of follicular tracheitis on bronchoscopy and objective evidence of gastroesophageal reflux disease. Retrospective chart review of children with recurrent croup having undergone a rigid bronchoscopy and an investigation for gastroesophageal reflux between 2001 and 2013. 117 children with recurrent croup children age 6-144 months were included in the study. Follicular tracheitis was noted on 41% of all bronchoscopies. Fifty-nine percent of all children who underwent bronchoscopy were diagnosed with gastroesophageal reflux on at least one investigation. Forty-nine of 117 children underwent a pH probe study, and 51% were found to have evidence of reflux on this study. Nine children were diagnosed with eosinophilic esophagitis. Three patients underwent a biopsy of the follicular tracheitis lesions, which revealed chronic inflammation. There was no evidence of an association between findings of follicular tracheitis and a positive test for gastroesophageal reflux (p=0.52) or a positive pH probe study (p=0.64). There was no association between follicular tracheitis and subglottic stenosis (p=0.33) or an history of asthma and/or atopy (p=0.19). In children with recurrent croup, follicular tracheitis remains an unspecific finding associated with an inflammatory disorder of unknown etiology. Copyright © 2015 Elsevier Ireland Ltd.

    2012-01-01

    Gastroesophageal reflux disease is mediated principally by acid. Today, we recognise reflux reaches beyond the esophagus, where pepsin, not acid, causes damage. Extraesophageal reflux occurs both as liquid and probably aerosol, the latter with a further reach. Pepsin is stable up to pH 7 and regains activity after reacidification. The enzyme adheres to laryngeal cells, depletes its defences, and causes further damage internally after its endocytosis. Extraesophageal reflux can today be detected by recognising pharyngeal acidification using a miniaturised pH probe and by the identification of pepsin in saliva and in exhaled breath condensate by a rapid, sensitive, and specific immunoassay. Proton pump inhibitors do not help the majority with extraesophageal reflux but specifically formulated alginates, which sieve pepsin, give benefit. These new insights may lead to the development of novel drugs that dramatically reduce pepsinogen secretion, block the effects of adherent pepsin, and give corresponding clinical benefit."For now we see through a glass, darkly."-First epistle, Chapter 13, Corinthians.

    OBJECTIVE Our goal is to determine if antimicrobial prophylaxis with trimethoprim/sulfamethoxazole prevents recurrent urinary tract infections and renal scarring in children who are found to have vesicoureteral reflux after a first or second urinary tract infection. DESIGN, PARTICIPANTS, AND METHODS The Randomized Intervention for Children With Vesicoureteral Reflux (RIVUR) study is a double-blind, randomized, placebo-controlled trial. Six hundred children aged 2 to 72 months will be recruited from both primary and subspecialty care settings at clinical trial centers throughout North America. Children who are found to have grades I to IV vesicoureteral reflux after the index febrile or symptomatic urinary tract infection will be randomly assigned to receive daily doses of either trimethoprim/sulfamethoxazole or placebo for 2 years. Scheduled follow-up contacts include in-person study visits every 6 months and telephone interviews every 2 months. Biospecimens (urine and blood) and genetic specimens (blood) will be collected for future studies of the genetic and biochemical determinants of vesicoureteral reflux, recurrent urinary tract infection, renal insufficiency, and renal scarring. RESULTS The primary outcome is recurrence of urinary tract infection. Secondary outcomes include time to recurrent urinary tract infection, renal scarring (assessed by dimercaptosuccinic acid scan), treatment failure, renal function, resource utilization, and development of antimicrobial resistance in stool flora. CONCLUSIONS The RIVUR study will provide useful information to clinicians about the risks and benefits of prophylactic antibiotics for children who are diagnosed with vesicoureteral reflux after a first or second urinary tract infection. The data and specimens collected over the course of the study will allow researchers to better understand the pathophysiology of recurrent urinary tract infection and its sequelae. PMID:19018048

  9. Gastroesophageal Reflux Disease and Alkaline Reflux: the Mechanisms of the Development and Therapeutic Approach

    Directory of Open Access Journals (Sweden)

    T.D. Zviahintseva

    2016-11-01

    Full Text Available The article deals with gastroesophageal reflux disease (GERD — a pathology, which occupies a leading place among all acid-related diseases. The main mechanism of GERD is a violation of the motor-evacuation function of the stomach — slowing gastric emptying and duodenogastric reflux. Slow gastric emptying contributes to more frequent reflux, and the presence of duodenal contents in refluxate — alkaline reflux — is aggressive for the esophageal mucosa (EM. This is due to the presence of bile acids, lysolecithin and pancreatic enzymes in the esophageal refluxate. A long existing contact of aggressive factors in the stomach and the esophagus leads to the development of inflammatory and destructive lesions of the mucous membrane of these organs. According to many researchers, bile acids play a key role in the pathogenesis of the damaging effects on the EM. Drug correction of GERD with alkaline reflux includes, along with the administration of proton pump inhibitors, prokinetics (itopride hydrochloride and ursodeoxycholic acid preparations.

    This study was conducted to investigate whether there is a direct association between subjective sleep quality and esophageal acid reflux in patients with gastroesophageal reflux disease. We enrolled patients with classic reflux symptoms for endoscopy and ambulatory pH monitoring. The severity of esophageal mucosal injury was assessed by upper endoscopy. Distal esophageal acid exposure was determined by ambulatory 24-hour pH monitoring. Sleep disturbance was assessed by using the Pittsburgh Sleep Quality Index. In total, 103 patients (53 patients without sleep dysfunction and 50 patients with sleep dysfunction) were studied. Erosive esophagitis was found more in patients with sleep disturbance than in those without sleep disturbance (45% versus 31%, P = 0.04). Abnormal esophageal pH was found more in patients with dysfunction (22%) than in patients without sleep dysfunction (5.7%, P = 0.03). Recumbent acid contact time (%) was greater in patients with sleep disturbance than in those without sleep disturbance (3.7 ± 2.4 versus 1.9 ± 0.9, P = 0.04). Sleep quality score positively correlated with acid contact time (r = 0.32, P = 0.02), prolonged reflux events (r = 0.45, P = 0.008) and longer reflux event (r = 0.28, P = 0.03) during recumbent period. Patients with gastroesophageal reflux disease along with sleep dysfunction are characterized with greater nocturnal acid reflux and more erosive esophagitis. Our study suggests that increased nocturnal acid reflux may play a role in inducing sleep disturbance in patients with gastroesophageal reflux disease.

    When a child is sick, parents want answers. They want to know what is wrong, what they can do, and how to get their child healthy--pronto. Regrettably, there are some puzzling illnesses affecting children that are surrounded by mystery. One of them is gastroesophageal reflux (GER), otherwise known as acid reflux--or "reflux" for short. Reflux…

    This article describes an environmental assessment of Swedish agriculture, including upstream and downstream effects. The analysis is based on environmentally extended input-output analysis, but it is also supplemented with data from other sources. The analysis shows that direct effects by the Swedish agriculture are the most important, while indirect effects from other sources including mobile and impacts abroad are also considerable. The most important impacts from Swedish agriculture according to the analysis are eutrophication, global warming and resource use. The agricultural sector produces a large share of the Swedish emissions causing both global warming and eutrophication. In addition, current agricultural practice causes problems with loss of biodiversity. The most important actors in the sector are agriculture itself, but also all actors using fossil fuels: primarily the transport sector and the energy sector. In addition, consumers are important since they can influence the composition of agricultural production. The analysis shows the importance of including upstream and downstream effects when analysing the environmental impacts from a sector. (author)

    Extravesical detrusorrhaphy is a simple and safe approach to antireflux surgery; however, its use in Taiwan has seldom been reported. We report the outcomes of 15 patients (23 ureters) with primary vesicoureteral reflux who underwent extravesical detrusorrhaphy between January 1995 and April 1996, and describe the surgical technique. Overall, vesicoureteral reflux was cured in 22 of 23 ureters. Postoperative morbidity and complications were minimal. None of the patients had obstruction or significant hematuria. The discomfort related to bladder spasms during the postoperative period was subjectively decreased compared to the conventional transvesical technique. There was transient voiding inefficiency in three patients, as well as urinary retention in one, which resolved spontaneously after 4 weeks of Foley catheter drainage. Our experience showed that detrusorrhaphy is an effective way to correct vesicoureteral reflux with minimal morbidity and discomfort. Proper patient selection and strict adherence to the surgical principle are important for high success rates.

    The vesical-ureteral reflux is the most frequent uropathy in children. The diagnosis is made by uretero-cystography, often after pyelonephritis, sometimes after ante-natal diagnosis from echographic abnormalities. Spontaneous recovery is possible in 50 to 80% of cases. This is especially true in grade 1, 2 and 3, however complications may occur. They are more frequent in the case of reflux nephropathy with a resulting risk of hypertension and chronic renal failure. The therapeutic choice is between the conservative management with urinary antiseptics ad the surgical treatment with ureters re-implantation or endoscopic treatment. The therapeutic indications take into account vesical-ureteral reflux grades, the child's age, the associated diseases and the child's and parents' compliance. (authors). 22 refs., 2 figs

    It is increasingly accepted that the effects of gastro-oesophageal reflux are not limited to the gastrointestinal tract. The adjacent respiratory structures are also at risk from material ejected from the proximal oesophagus as a result of the failure of anatomical and physiological barriers. There is evidence of the influence of reflux on several respiratory and otorhinological conditions and although in many cases the precise mechanism has yet to be elucidated, the association alone opens potential novel avenues of therapy to clinicians struggling to treat patients with apparently intractable respiratory complaints. This review provides a description of the airway reflux syndrome, its effects on the lung and current and future therapeutic options. PMID:23251752

    A group of 97 individuals with typical symptoms of gastroesophageal reflux disease (GERD) was submitted to gastroesophageal reflux scintigraphy (GES) and compared to the results obtained from endoscopy, histopathology and 24 hours pHmetry. Twenty-four healthy individuals were used as a control group and they have done only the GERS. The results obtained showed that: a) the difference int he reflux index (RI) for the control group and the sick individuals was statistically significant (p < 0.0001); b) the correlation between GERS and the other methods showed the following results: sensitivity, 84%; specificity, 95%; positive predictive value, 98%; negative predictive value, 67%; accuracy, 87%. We have concluded that the scintigraphic method should be used to confirm the diagnosis of GERD and also recommended as initial investiative procedure. (author)

    Upper gastrointestinal endoscopy and radiologic examination were performed in 101 patients with symptoms strongly suggestive of gastroesophageal reflux (GER) disease. Hiatus hernia (HH) was found in 50 patients diagnosed by radiography or endoscopy, or both, in 22, 19, and 9 patients respectively. Severe endoscopic esophagitis (grades III and IV) was found more often in the patients with HH than in those without. The same was true for the early positive timed acid perfusion tests. Furthermore, the patients with HH more often had reflux by the standard acid reflux test (42 og 50 versus 28 of 51, gastroesophageal scintigraphy (47 of 50 versus 40 of 51; and radiography (20 of 50 versus 2 of 51; than the patients without HH. The results show that severe GER disease can occur without an associated HH and indicate that patients with symptoms of GER disease and associated HH are likely to have a more severe GER disease than those without HH.

    Severe symptoms of heartburn and retrosternal pain consistent with gastro-esophageal reflux (GER) developed in a patient following placement of a conventional self-expanding 16-24-mm-diameter x 12-cm-long esophageal stent across the gastroesophageal junction to treat an obstructing esophageal carcinoma. A second 18-mm-diameter x 10-cm-long esophageal stent with anti-reflux valve was deployed coaxially and reduced symptomatic GER immediately. Improvement was sustained at 4-month follow-up. An anti-reflux stent can be successfully used to treat significant symptomatic GER after conventional stenting

    Proton pump inhibitors are the most effective medical therapy for gastroesophageal reflux disease, but their onset of action may be slow. To assess the available literature regarding the efficacy of omeprazole/sodium bicarbonate in gastroesophageal reflux patients. A systematic review was conducted. A systematic literature search starting from 2000. Reviewed manuscripts concerning the effectiveness of omeprazole/sodium bicarbonate treatment in gastroesophageal reflux disease were reviewed and the data were extracted. Data were subsequently analyzed with descriptive statistics. This review included information of four studies. Two trials compared the efficacy of omeprazole/sodium bicarbonate versus omeprazole. One study compared the efficacy of once-daily morning or nighttime dosing. And another study compared omeprazole/sodium bicarbonate/alginate versus omeprazole. In total, there was no difference between omeprazole/sodium bicarbonate and omeprazole. However, there is a trend towards more sustained response and a greater proportion of patients with sustained total relief by 30 minutes with omeprazole/sodium bicarbonate. Omeprazole/sodium bicarbonate therapy is not more effective than omeprazole in the treatment of gastroesophageal reflux disease. However, data obtained suggest that it can have a more sustained response and sustained total relief.

    Full Text Available Purpose. In recent years, endoscopic injection became the procedure of choice for the correction of vesicoureteral reflux in the majority of the centers. Unfortunately, endoscopic treatment is not always successful and sometimes requires more than one trial to achieve similar results to that of an open reimplantation surgery. Our aim of this study is to evaluate the feasibility and success rate of open ureteral reimplantation following failed endoscopic procedure. Patients and Methods. During 2004–2010, we evaluated 16 patients with persistent vesicoureteral reflux (grades II–IV following failed endoscopic treatment. All patients underwent open ureteral reimplantation. All patients were followed with an ultrasound 6 weeks following surgery and every 6 months thereafter for an average of 22 months. Voiding cystography was performed at 3 months after surgery. Results. During unilateral open ureteral reimplantation, the implanted deposit from previous procedures was either excised, drained, or incorporated into the neotunnel with the ureter. Vesicoureteral reflux was resolved in all patients with 100% success rate. No new hydronephrosis or signs of obstruction developed in any of the patients. qDMSA renal scan was available in 8 patients showing improvement of function in 5 and stable function in 3, and no new scars were identified. Conclusions. Open ureteral reimplantation is an excellent choice for the correction of failed endoscopic treatment in children with vesicoureteral reflux.

    The objective of this study is to determine the efficacy of adding a prokinetic agent to proton pump inhibitors (PPI) for the treatment of laryngopharyngeal reflux (LPR) disease. A prospective, randomized open trial comparing lansoprazole plus itopride to lansoprazole single therapy was performed for 12 weeks. Sixty-four patients with a reflux finding score (RFS) >7 and a reflux symptom index (RSI) >13 were enrolled and received either lansoprazole 30 mg once daily with itopride 50 mg three times daily or lansoprazole 30 mg once daily for 12 weeks. RSI and RFS were completed at baseline, after 6 weeks, and after 12 weeks. During the treatment period, RSI and RFS were significantly improved compared with the pretreatment scores in both study groups. Reductions of total RSI and globus symptom were significantly higher in the lansoprazole plus itopride group compared to the lansoprazole group. In the RFS, however, there were no significant differences between the two groups. In conclusion, itopride in addition to PPI did not show any superior RFS improvement compared to PPI single therapy, but was helpful in speeding up relief of reflux symptoms in LPR patients. Thus, itopride may be considered as the secondary additive agent in the PPI treatment of LPR patients.

  4. Sulfur problems in Swedish agriculture

    1959-01-01

    The present paper deals with some aspects of the sulfur situation in Swedish agriculture with special emphasis on the importance of and relationships among various sources of sulfur supply. An inventory of the sulfur content of Swedish soils and hay crops includes 649 soil samples and a corresponding number of hay samples from 59 locations. In a special investigation the samples were found to be representative of normal Swedish farm land. It is concluded that the amount of sulfur compounds in the air is the primary factor which determines the amount of sulfur added to the soil from the atmosphere. Compared with values obtained in other countries, the amount of sulfur added by the precipitation in Sweden is very low. The distribution in air and precipitation of sulfur from an industrial source was studied in a special investigation. An initial reason for the present study was the damage to vegetation caused by smoke from an industrial source. It was concluded that the average conditions in the vicinity of the industrial source with respect to smoke constituents in the air and precipitation were unfavorable only to the plants directly within a very narrow region. Relationships among the sulfur contents of air, of precipitation, of soils and of plants have been subject to special investigations. In the final general discussion and conclusions it is pointed out that the results from these investigations indicate evident differences in the sulfur status of Swedish soils. The present trend toward the use of more highly concentrated fertilizers poor in sulfur may be expected to cause a considerable change in the sulfur situation in Swedish agriculture. 167 references, 40 figures, 44 tables.

    To examine the relationship between nocturnal bruxism and gastroesophageal reflux. Controlled descriptive study and double-blind, placebo-controlled, clinical study. Portable pH monitoring, electromyography, and audio-video recordings were conducted during the night in the subjects' home. Ten patients with bruxism and 10 normal subjects were matched for height, weight, age, and sex. They did not have symptoms of gastroesophageal reflux disease. Medication with a proton pump inhibitor (ie, a gastric-acid-inhibiting drug). The bruxism group showed a significantly higher frequency of nocturnal rhythmic masticatory muscle activity (RMMA) episodes (mean +/- SD: 6.7 +/- 2.2 times per hour) and a higher frequency and percentage of time of gastroesophageal reflux episodes with a pH less than 4.0 and 5.0 (0.5 +/- 0.9 and 3.6 +/- 1.6 times per hour and 1.3% +/- 2.5% and 7.4% +/- 12.6%, respectively) than the control group (RMMA episodes: 2.4 +/- 0.9 times per hour; gastroesophageal reflux episodes: 0.0 +/- 0.0 and 0.1 +/- 0.3 times per hour and 0.0% +/- 0.0% and 0.0% +/- 0.0%, respectively). In the bruxism group, 100% of the gastroesophageal reflux episodes with a pH less than 3.0 and 4.0 included both an RMMA episode and an electromyographic burst, the duration of which was approximately 0.5 to 1.0 seconds, probably representing swallowing of saliva. The majority of gastroesophageal reflux episodes with a pH of 4.0 to 5.0 also included both an RMMA episode and an electromyographic burst in the control and bruxism groups (100% +/- 0.0% vs 70.7% +/- 16.5%), again probably due to swallowing of saliva. The remaining minority of gastroesophageal reflux episodes with a pH of 4.0 to 5.0 contained only an electromyographic burst (swallowing of saliva). The frequency of RMMA episodes after the release of the medication from the proton pump inhibitor, which increased the gastric and esophageal pH, was significantly lower than that after administration of the placebo in the control

    Gastroesophageal reflux disease (GERD) is one of the most common problems treated by primary care physicians. Almost 20% of the population in the United States experiences occasional regurgitation, heartburn, or retrosternal pain because of GERD. Reflux disease is complex, and the physiology and pathogenesis are still incompletely understood. However, abnormalities of any one or a combination of the three physiologic processes, namely, esophageal motility, lower esophageal sphincter function, and gastric motility or emptying, can lead to GERD. There are many diagnostic and therapeutic approaches to GERD today, but more studies are needed to better understand this complex disease process. Copyright © 2015 Elsevier Inc. All rights reserved.

    Gastroesophageal reflux (GER) is common in infancy and mainly treated through nonpharmacological interventions. Knowing the early warning signs of GER is important for nursing assessment. Untreated GER can become acute when an infant fails to gain weight and has recurrent, forceful vomiting. Further investigation of gastroesophageal reflux disease (GERD) is indicated when failure to gain weight, irritability, swallowing difficulties, regurgitation, and respiratory complications occur and should trigger referral to pediatric specialists. This article will share information about uncomplicated GER, GERD, and symptoms of these diagnoses, common screening tests, and treatment options. Copyright © 2017 Elsevier Inc. All rights reserved.

    The association of gastroesophageal reflux disease and its pulmonary manifestation is well known however the exact underlying mechanism is unclear. The medical literature is deluged with studies on relationship between Gear and its pulmonary manifestations. The aim of this study was to 1) determine prevalence of GER in children with rLRTI, wheezing and asthma. 2) determine prevalence of asymptomatic respiratory anomalies in children with clinical reflux 3) determine effectiveness of anti-reflux therapy in clinical control of asthma, wheezing and rLRTI. Children were included in the study if they presented either with rLRTI, wheezing, Bronchial asthma or Clinical suspicion of GER without any respiratory symptoms. The GER study comprised esophageal transit, gastroesophageal reflux and lung aspiration studies. Acquisition and processing were according to predetermined protocol. Segmental and global esophageal transit times, GER according to duration of episode and volume of refluxed liquid, Reflux severity, Gastric retention at 30 minutes, Gastric emptying time, Presence of lung aspiration were calculated for each study. All children underwent Barium studies on a separate day. Clinical follow-up was done every 3 months and GER study was repeated every 6 months up to one year. The patient's therapy was determined by local protocols at discretion of clinicians. GER scintigraphy was performed in 43 patients (age range 5 months -12 years). Gastroesophageal reflux of varying degrees was observed in 10 children (23.25%) in all groups. The severity of clinical symptoms was directly related to severity of GER. The direct correlation was found between GER and reflux index. The results of GER scintigraphy were compared with Barium studies and results were found to be superior in terms of sensitivity, specificity and accuracy in detecting disease. It was possible to objectively evaluate and monitor response to therapy after medical treatment in few cases with help of follow

For the clinical examinations, he referred to patients complaining the reflux difficulties or patients who had had a Balanced Operation because of a reflux disease. The main concern was to clarify the special characteristics and the reliability of reflux scintiscanning and to compare them to conventional methods of radiological and endoscopic reflux diagnostics.

    Gastro-oesophageal reflux (GOR) is a common disorder, characterised by regurgitation of gastric contents into the oesophagus. GOR is a very common presentation in infancy in both primary and secondary care settings. GOR can affect approximately 50% of infants younger than three months old (Nelson 1997). The natural history of GOR in infancy is generally that of a functional, self-limiting condition that improves with age; gastro-oesophageal reflux disease (GORD) and its precise distinction from GOR are debated, but consensus guidelines from the North American Society of Gastroenterology, Hepatology and Nutrition (NASPGHAN-ESPGHAN guidelines 2009) define GORD as 'troublesome symptoms or complications of GOR.' This Cochrane review aims to provide a robust analysis of currently available pharmacological interventions used to treat children with GOR by assessing all outcomes indicating benefit or harm. We sought to identify relevant published trials by searching the Cochrane Central Register of Controlled Trials (CENTRAL) (2014, Issue 5), MEDLINE and EMBASE (1966 to 2014), the Centralised Information Service for Complementary Medicine (CISCOM), the Institute for Scientific Information (ISI) Science Citation Index (on BIDS-UK General Science Index) and the ISI Web of Science. We also searched for ongoing trials in the metaRegister of Controlled Trials (mRCT) (www.controlled-trials.com).Reference lists from trials selected by electronic searching were handsearched for relevant paediatric studies on medical treatment of children with gastro-oesophageal reflux, as were published abstracts from conference proceedings (published in Gut and Gastroenterology) and reviews published over the past five years.No language restrictions were applied. Abstracts were reviewed by two review authors, and relevant RCTs on study participants (birth to 16 years) with GOR receiving a pharmacological treatment were selected. Subgroup analysis was considered for children up to 12 months of age

    Background The role of sexual activity on gastroesophageal reflux disease (GERD) is an under-recognized concern of patients, and one rarely assessed by physicians. Objective The objective of this article is to determine the influence of sexual activity on the intraesophageal acid exposure and acid reflux events in GERD patients. Methods Twenty-one patients with the diagnosis of GERD were prospectively enrolled. Intraesophageal pH monitoring was recorded for 48 hours with a Bravo capsule. All patients were instructed to have sexual intercourse or abstain in a random order two hours after the same refluxogenic dinner within two consecutive nights. Patients were requested to have sex in the standard “missionary position” and women were warned to avoid abdominal compression. The patients completed a diary reporting the time of the sexual intercourse and GERD symptoms. The percentage of reflux time and acid reflux events were compared in two ways: within 30 and 60 minutes prior to and after sexual intercourse on the day of sexual intercourse and in the same time frame of the day without sexual intercourse. Results Fifteen of 21 GERD patients were analyzed. The percentage of reflux time and number of acid reflux events did not show a significant difference within the 30- and 60-minute periods prior to and after sexual intercourse on the day of sexual intercourse and on the day without sexual intercourse, as well. Conclusion Sexual activity does not predispose to increased intraesophageal acid exposure and acid reflux events. Larger studies are needed to confirm our findings in patients who define reflux symptoms during sexual intercourse. PMID:25452843

    Laparoscopic sleeve gastrectomy (LSG) has gained significant popularity in the USA, and consequently resulted in patients experiencing new-onset gastroesophageal reflux disease (GERD) following this bariatric procedure. Patients with GERD refractory to medical therapy present a more challenging situation limiting the surgical options to further treat the de novo GERD symptoms since the gastric fundus to perform a fundoplication is no longer an option. The aim of this study is to determine if the LINX® magnetic sphincter augmentation system is a safe and effective option for patients with new gastroesophageal reflux disease following laparoscopic sleeve gastrectomy. This study was conducted at the University Medical Center. This is a retrospective review of seven consecutive patients who had a laparoscopic LINX® magnetic sphincter device placement for patients with refractory gastroesophageal reflux disease after laparoscopic sleeve gastrectomy between July 2014 and April 2015. All patients were noted to have self-reported greatly improved gastroesophageal reflux symptoms 2-4 weeks after their procedure. They were all noted to have statistically significant improved severity and frequency of their reflux, regurgitation, epigastric pain, sensation of fullness, dysphagia, and cough symptoms in their postoperative GERD symptoms compared with their preoperative evaluation. This is the first reported pilot case series, illustrating that the LINX® device is a safe and effective option in patients with de novo refractory gastroesophageal reflux disease after a laparoscopic sleeve gastrectomy despite appropriate weight loss.

    Reflux of bile and digestive enzymes from the small bowel and duodenum into stomach has been observed in patients with various gastroduodenal diseases. Tc-99m iminodiacetic acid derivatives hepatobiliary scan has been used as a noninvasive method to detect duodenogastric reflux. Sometimes, gastric reflux can be observed incidentally on routine Tc-99m DISA hepatobiliary scintigraphy. To evaluate the clinical meaning of gastric reflux on routine Tc-99m DISIDA hepatobiliary scan, we analyzed 36 patients showed gastric reflux incidentally on the routine Tc-99m-DISIDA hepatobiliary scintigraphy from December 1991 to June 1995 in Chungnam National University Hospital. The results were as follows: 1) The gastric reflux was observed in 2.3% of 1,553 cases of routine Tc-99m DISIDA Hepatobiliary scintigraphy for 43 months. 2) Nineteen percent of patients with gastric reflux had the past medical history of operations on stomach or biliary system. And that history was more prevalent in patients with reflux than those without reflux, significantly (p<0.01). 3) On fiberoptic gastroduodenpscopic examination, 87% of the patients with gastric reflux had the gastroduodenal diseases such as gastritis, gastric ulcer, duodenal ulcer, gastric cancer, duodenal cancer and ampullary diverticulosis. We thought that the gastric reflux can be observed considerably in patients without any operation history on stomach or duodenum, although the operation history is more prevalent in patients with gastric reflux than those without reflux, significantly and most of patients with gastric reflux on routine Tc-99m DISIDA scan has various gastroduodenal diseases.

    Reflux of bile and digestive enzymes from the small bowel and duodenum into stomach has been observed in patients with various gastroduodenal diseases.

    Gastric emptying has an important role in the pathophysiology of gastroesophageal reflux disease. The effect of metoclopramide, a gastric prokinetic agent, in gastroesophageal reflux patients with normal as well as delayed emptying was investigated. Twenty-six patients with subjective and objective evidence of gastroesophageal reflux ingested an egg salad sandwich meal labeled with /sub 99m/technetium-DTPA for a baseline study, and then again on a separate day after receiving oral metoclopramide, 10 mg, 30 min prior to the test meal. The mean percent isotope remaining in the stomach after 90 min improved significantly from 70.3 +/- 3.9% (SEM) to 55.2 +/- 4.2% after metoclopramide. Fourteen (54%) had a basal emptying in the normal range of 34-69% retention of isotope at 90 min, (means +/- 2 SD), while it was slow in 12 (46%). For those with delayed basal gastric emptying, the mean retention of 88.9 +/- 2.9% at 90 min was significantly decreased by metoclopramide to 68.6 +/- 6.1%. In those patients with a normal basal gastric emptying and a mean retention of 54.4 +/- 2.3% at 90 min, there was also significant improvement (P less than 0.025) to 43.6 +/- 3.6% after metoclopramide. These data indicate that metoclopramide increased gastric emptying in gastroesophageal reflux patients with normal as well as delayed gastric emptying. Therefore on a patient management level a trial of metoclopramide is warranted in patients with gastroesophageal reflux disease and is not limited by the gastric emptying status of the patient.

    Between 1949 and 1957, 10 engineers of the Mining research and exploitation department of the CEA visited 17 Swedish mines during 5 field trips. This paper presents a compilation of the information gathered during these field trips concerning the different underground mining techniques used in Swedish iron mines: mining with backfilling (Central Sweden and Boliden mines); mining without backfilling (mines of the polar circle area). The following techniques are described successively: pillar drawing and backfilled slices (Ammeberg, Falun, Garpenberg, Boliden group), sub-level pillar drawing (Grangesberg, Bloettberget, Haeksberg), empty room and sub-level pillar drawing (Bodas, Haksberg, Stripa, Bastkarn), storage chamber pillar drawing (Bodas, Haeksberg, Bastkarn), and pillar drawing by block caving (ldkerberget).

    1997-12-31

    This thesis studies the separation of gas mixtures in a reflux condenser. also called a dephlegmator. Reflux condensation is separation of a gas mixture, in reflux flow with condensing liquid, under continuous heat removal. A numerical model of a dephlegmator for binary mixtures was developed. The model may readily be extended to multi-component mixtures, as the solution method is based on a matrix solver. Separation of a binary mixture in a reflux condenser test rig is demonstrated. The test facility contains a single-tube test section that was designed and built as part of the project. Test mixtures of propane and n-butane were used, and a total of 15 experiments are reported. Limited degree of separation was achieved due to limited heat transfer area and narrow boiling point range of the test mixture. The numerical model reproduces the experimental data within reasonable accuracy. Deviation between calculated and measured properties is less than 6% of the measured temperature and less than 5% of the measured flow rate. The model is based on mechanistic models of physical processes and is not calibrated or tuned to fit the experimental data. The numerical model is applied to a number of separation processes. These case studies show that the required heat transfer area increases rapidly with increments in top product composition (light component). Flooding limits the amount of reflux liquid. The dephlegmator is suitable for separation of feed mixtures that are rich in light components. The gliding temperature in the dephlegmation process enables utilization of top product as refrigerant, with subsequent energy saving as a result. 61 refs., 50 figs., 34 tabs.

    2009-01-01

    Full Text Available Objectives: The aim of this review was to systematically examine the available evidence for the effectiveness of prophylactic antibiotics in cases of vesicoureteric reflux (VUR. Materials and Methods: We searched the relevant data on medical management of VUR and the date of last search was June 2008. The search included both randomized controlled trials as well as the nonrandomized trials and the data sources were; MEDLINE, online peer reviewed journals, Cochrane database and abstracts from conference proceedings. Results: Barring few most of the studies published on medical management were nonrandomized. Besides being small in number many of these studies were of poor-quality and poorly designed eventually failing in giving a reliable answer in this regard. Few of the studies suggest that the children with low grade VUR might do well even without antibiotic prophylaxis. Conclusions : In the absence of properly designed, randomized controlled trials and long-term follow-up the question of antibiotic prophylaxis in cases of VUR remains unanswered in large part of it. Whether to give prophylactic antibiotics or not would ultimately need a shared decision-making involving both the treating physician and the parents assessing both the risks and the benefits.

  12. Swedish earthquakes and acceleration probabilities

    International Nuclear Information System (INIS)

    Slunga, R.

    1979-03-01

    A method to assign probabilities to ground accelerations for Swedish sites is described. As hardly any nearfield instrumental data is available we are left with the problem of interpreting macroseismic data in terms of acceleration. By theoretical wave propagation computations the relation between seismic strength of the earthquake, focal depth, distance and ground accelerations are calculated. We found that most Swedish earthquake of the area, the 1904 earthquake 100 km south of Oslo, is an exception and probably had a focal depth exceeding 25 km. For the nuclear power plant sites an annual probability of 10 -5 has been proposed as interesting. This probability gives ground accelerations in the range 5-20 % for the sites. This acceleration is for a free bedrock site. For consistency all acceleration results in this study are given for bedrock sites. When applicating our model to the 1904 earthquake and assuming the focal zone to be in the lower crust we get the epicentral acceleration of this earthquake to be 5-15 % g. The results above are based on an analyses of macrosismic data as relevant instrumental data is lacking. However, the macroseismic acceleration model deduced in this study gives epicentral ground acceleration of small Swedish earthquakes in agreement with existent distant instrumental data. (author)

  13. Energy efficiency in Swedish industry

    2016-01-01

    This paper assesses energy efficiency in Swedish industry. Using unique firm-level panel data covering the years 2001–2008, the efficiency estimates are obtained for firms in 14 industrial sectors by using data envelopment analysis (DEA). The analysis accounts for multi-output technologies where undesirable outputs are produced alongside with the desirable output. The results show that there was potential to improve energy efficiency in all the sectors and relatively large energy inefficiencies existed in small energy-use industries in the sample period. Also, we assess how the EU ETS, the carbon dioxide (CO_2) tax and the energy tax affect energy efficiency by conducting a second-stage regression analysis. To obtain consistent estimates for the regression model, we apply a modified, input-oriented version of the double bootstrap procedure of Simar and Wilson (2007). The results of the regression analysis reveal that the EU ETS and the CO_2 tax did not have significant influences on energy efficiency in the sample period. However, the energy tax had a positive relation with the energy efficiency. - Highlights: • We use DEA to estimate firm-level energy efficiency in Swedish industry. • We examine impacts of climate and energy policies on energy efficiency. • The analyzed policies are Swedish carbon and energy taxes and the EU ETS. • Carbon tax and EU ETS did not have significant influences on energy efficiency. • The energy tax had a positive relation with energy efficiency.

    Gastroesophageal reflux disease (GERD) is diagnosed based on typical symptoms in clinical practice. It can be divided into two groups using endoscopy: erosive and nonerosive reflux disease (NERD). This study aims to determine the risk factors of reflux symptoms and mucosal injury. This was a two-step case-control study derived from a cohort of 998 individuals having the data of reflux disease questionnaire (RDQ) and endoscopic findings. Those with minor reflux symptoms were excluded. The first step compared symptomatic GERD patients with healthy controls. The 2(nd) step compared patients with erosive esophagitis with healthy controls. In this study, the prevalence of symptomatic GERD and erosive esophagitis were 163 (16.3%) and 166 (16.6%), respectively. A total of 507 asymptomatic individuals without mucosal injury of the esophagus on endoscopy were selected as healthy controls. Compared with healthy controls, multivariate analyses showed that symptomatic GERD patients had a higher prevalence of hypertriglyceridemia [odds ratio (OR), 1.83; 95% confidence interval (CI) 1.13-2.96] and obesity (OR, 1.85; 95% CI 1.08-3.02). By contrast, male sex (OR, 2.24; 95% CI 1.42-3.52), positive Campylo-like organism (CLO) test (OR, 0.56; 95% CI 0.37-0.84), and hiatus hernia (OR, 14.36; 95% CI 3.05-67.6) were associated with erosive esophagitis. In conclusion, obesity and hypertriglyceridemia were associated with reflux symptoms. By contrast, male sex, negative infection of Helicobacter pylori, and hiatus hernia were associated with mucosal injury. Our results suggested that risk factors of reflux symptoms or mucosal injury might be different in GERD patients. The underlying mechanism awaits further studies to clarify. Copyright © 2015.

  17. Systematic review: relationships between sleep and gastro-oesophageal reflux.

    Gastro-oesophageal reflux disease (GERD) adversely impacts on sleep, but the mechanism remains unclear. To review the literature concerning gastro-oesophageal reflux during the sleep period, with particular reference to the sleep/awake state at reflux onset. Studies identified by systematic literature searches were assessed. Overall patterns of reflux during the sleep period show consistently that oesophageal acid clearance is slower, and reflux frequency and oesophageal acid exposure are higher in patients with GERD than in healthy individuals. Of the 17 mechanistic studies identified by the searches, 15 reported that a minority of reflux episodes occurred during stable sleep, but the prevailing sleep state at the onset of reflux in these studies remains unclear owing to insufficient temporal resolution of recording or analysis methods. Two studies, in healthy individuals and patients with GERD, analysed sleep and pH with adequate resolution for temporal alignment of sleep state and the onset of reflux: all 232 sleep period reflux episodes evaluated occurred during arousals from sleep lasting less than 15 s or during longer duration awakenings. Six mechanistic studies found that transient lower oesophageal sphincter relaxations were the most common mechanism of sleep period reflux. Contrary to the prevailing view, subjective impairment of sleep in GERD is unlikely to be due to the occurrence of reflux during stable sleep, but could result from slow clearance of acid reflux that occurs during arousals or awakenings from sleep. Definitive studies are needed on the sleep/awake state at reflux onset across the full GERD spectrum. © 2013 John Wiley & Sons Ltd.

  19. Respiratory and laryngeal symptoms secondary to gastro-oesophageal reflux

    Science.gov (United States)

    Rafferty, G; Mainie, I; McGarvey, L P A

    2011-01-01

    Gastro-oesophageal reflux may cause a range of laryngeal and respiratory symptoms. Mechanisms responsible include the proximal migration of gastric refluxate beyond the upper oesophageal sphincter causing direct irritation of the larynx and lower airway. Alternatively, refluxate entering the distal oesophagus alone may stimulate oesophageal sensory nerves and indirectly activate airway reflexes such as cough and bronchospasm. Recognising reflux as a cause for these extraoesophageal symptoms can be difficult as many patients do not have typical oesophageal symptoms (eg, heartburn) and clinical findings on laryngoscopy are not very specific. Acid suppression remains an effective treatment in the majority of patients but there is growing appreciation of the need to consider and treat non-acid and volume reflux. New opinions about the role of existing medical and surgical (laparoscopic techniques) treatment are emerging and a number of novel anti-reflux treatments are under development. PMID:28839612

  20. Gastroesophageal Reflux and Idiopathic Pulmonary Fibrosis: A Review

    Directory of Open Access Journals (Sweden)

    Ahmed Fahim

    2011-01-01

    Full Text Available The histological counterpart of idiopathic pulmonary fibrosis is usual interstitial pneumonia, in which areas of fibrosis of various ages are interspersed with normal lung. This pattern could be explained by repeated episodes of lung injury followed by abnormal wound healing responses. The cause of the initiating alveolar epithelial injury is unknown, but postulated mechanisms include immunological, microbial, or chemical injury, including aspirated gastric refluxate. Reflux is promoted by low basal pressure in the lower oesophageal sphincter and frequent relaxations, potentiated by hiatus hernia or oesophageal dysmotility. In susceptible individuals, repeated microaspiration of gastric refluxate may contribute to the pathogenesis of IPF. Microaspiration of nonacid or gaseous refluxate is poorly detected by current tests for gastroesophageal reflux which were developed for investigating oesophageal symptoms. Further studies using pharyngeal pH probes, high-resolution impedance manometry, and measurement of pepsin in the lung should clarify the impact of reflux and microaspiration in the pathogenesis of IPF.

    Adolescents' alcohol consumption is a public health concern in Sweden as well as in many other countries. Underage drinking is associated with increased risks of alcohol-related injuries, risky sexual behaviours and dependence later in life. Different strategies have been used in the effort to prevent this behaviour, and to postpone the onset of alcohol. The Strengthening Families Programme 10-14 (SFP 10-14) from the USA has been highlighted as one of the more effective prevention programmes. The aim of the present article was to evaluate the effectiveness of a culturally adapted Swedish version of the SFP 10-14. This was a cluster randomized controlled trial including 587 sixth-grade students (age 12) and their parents in 19 elementary schools in Stockholm. Schools were randomly assigned to either control (9 schools, 216 students) or to the family skills training intervention (10 schools, 371 students). The SFP Swedish version consisted of two parts with seven and five sessions, respectively, held separately for youths and parents except two joint family sessions. Measures of students' self-reported episodes of drunkenness, smoking, illicit drug use and other norm-breaking behaviours were collected at baseline (March 2003) and at three subsequent yearly surveys. Data were analysed using multilevel models with an intention-to-treat approach. No preventive effects were found for smoking, alcohol and illicit drug use and other norm-breaking behaviours, nor did moderators affect the outcome. The Swedish version of the SFP 10-14 was not effective in preventing youths' substance use in a Swedish context. © The Author 2013.

    Gastroesophageal reflux disease (GERD) and/or hiatus hernia (HH) are one of the most common disorders of the upper gastrointestinal tract. Despite the positive effect of sleeve gastrectomy (SG) regarding weight loss and improvement in obesity co-morbidities, there are concerns about the development of de novo gastroesophageal reflux disease or worsening the existing GERD after this bariatric operation. Furthermore, controversy exists on the consequences of SG in lower esophageal sphincter function and about the ideal procedure when a hiatus hernia is preoperatively diagnosed or discovered during the laparoscopic SG. This review systematically investigates the incidence, the pathophysiology of GERD and/or HH in morbidly obese individuals before and after SG, and the treatment options for concomitant HH repair during laparoscopic sleeve gastrectomy.

    Full Text Available Gastro-esophageal reflux (GER is common in infants and children and has a varied clinical presentation: from infants with innocent regurgitation to infants and children with severe esophageal and extra-esophageal complications that define pathological gastro-esophageal reflux disease (GERD. Although the pathophysiology is similar to that of adults, symptoms of GERD in infants and children are often distinct from classic ones such as heartburn. The passage of gastric contents into the esophagus is a normal phenomenon occurring many times a day both in adults and children, but, in infants, several factors contribute to exacerbate this phenomenon, including a liquid milk-based diet, recumbent position and both structural and functional immaturity of the gastro-esophageal junction. This article focuses on the presentation, diagnosis and treatment of GERD that occurs in infants and children, based on available and current guidelines.

    Twenty-five infants and children with proved gastroesophageal reflux were studied by radionuclide gastroesophagography to determine its sensitivity in detecting reflux. Patients swallowed an inert radiotracer (Tc-99m sulfur colloid) and gamma camera images of the stomach and esophagus were made with and without abdominal pressure. The test was easy to perform and was well tolerated. Reflux was demonstrated in 20 patients (80%); this compared favorably with barium gastroesophagography

    Our main objective was to study gastritis associated to duodeno-gastric reflux. It is about a longitudinal study case/witness, paired according to the sex and the age. It was unrolled from February 2005 to January 2006 in the digestive diseases department of the hospital Gabriél Touré, and endoscopic centers of Promenade des Angevins, and clinique Farako. The patients profited from an upper digestive endoscopy to appreciate endoscopic aspect of gastritis associated to bile in the stomach mucus lake. The gastric biopsies were systematic. This study included 50 patients having gastritis associated to bile in gastric mucus lake compared to 50 patients having gastritis associated to clearly gastric mucus lake. The sex-ratio was 1.26 in favour of men. The average age of the patients was of 41.30 +/- 15.43 years. On the symptomatic hand, fetid breath was significantly met in duodeno-gastric reflux (p = 0.013). Potash consumption in the "tô" (millet cake) was significantly reported in gastritis associated to bile in gastric mucus lake (p = 0.042). The endoscopic aspects were comparable. Histological aspects of nonatrophic chronic gastritis were significantly mint in witnesses as well into the antrum as into the fundus (p = 0.0001 and p = 0.00023). The reactional gastritis aspect was the prerogative of duodenogastric reflux (p ranging between 10(-6) and 3.10 (-6). Helicobacter pylori infection was found comparable in the two groups (p = 0.297). Dysplasia although rare was found only in gastritis associated to duodeno-gastric reflux. Gastritis associated to bile in gastric mucus does not se,nm to have specific clinical, endoscopic and histological presentation. However the presence of dysplasia must have an attentive monitoring.

    Full Text Available Objective: to evaluate cellular energy metabolism in children with pathological gastroesophageal reflux, by determining the levels of free and bound carnitine in dry blood spot specimens and lactate and pyruvate in plasma.Characterization of children and methods. A total of 49 patients from the Diagnostic Department, Republican Children’s Clinical Hospital, Ministry of Health of the Republic of Tatarstan, were examined. A study group included 29 patients diagnosed as having reflux esophagitis. A control group consisted of 20 somatically healthy children without signs of gastrointestinal tract diseases. The investigators determined the levels of lactate and pyruvate in plasma by the Umbreit method and those of free and bound carnitine in the dried blood spot specimens by liquid chromatography-tandem mass spectrometry.Results. There were significant changes in the lactate-to-pyruvate ratio in children with reflux esophagitis accompanied by motility disorders. The values of free carnitine were higher than normal in 41% of the study group representatives. The mean values of lactate, pyruvate, and carnitines were within the acceptable range in the examined groups with significantly high values in the children with pathological gastroesophageal reflux.Conclusion. Gastrointestinal tract motility disorders are an indication for the detection of  energy-deficient diathesis in children and the early correction with energy-rich medications that will potentially affect the rate of recurrences and the severity of clinical manifestations of the disease.

    Full text: The Swedish mutation research programme in barley began about 50 years ago and has mainly been carried out at Svaloev in co-operation with the institute of Genetics at the University of Lund. The collection has been produced from different Swedish high-yielding spring barley varieties, using the following mutagens: X-rays, neutrons, several organic chemical compounds such as ethyleneimine, several sulfonate derivatives and the inorganic chemical mutagen sodium azide. Nearly 10,000 barley mutants are stored in the Nordic Gene Bank and documented in databases developed by Udda Lundquist, Svaloev AB. The collection consists of the following nine categories with 94 different types of mutants: 1. Mutants with changes in the spike and spikelets; 2. Changes in culm length and culm composition; 3. Changes in growth types; 4. Physiological mutants; 5. Changes in awns; 6. Changes in seed size and shape; 7. Changes in leaf blades; 8. Changes in anthocyanin and colour; 9. Resistance to barley powdery mildew. Barley is one of the most thoroughly investigated crops in terms of induction of mutations and mutation genetics. So far, about half of the mutants stored at the Nordic Gene Bank, have been analysed genetically; They constitute, however, only a minority of the 94 different mutant types. The genetic analyses have given valuable insights into the mutation process but also into the genetic architecture of various characters. A number of mutants of two-row barley have been registered and commercially released. One of the earliest released, Mari, an early maturing, daylength neutral, straw stiff mutant, is still grown in Iceland. The Swedish mutation material has been used in Sweden, but also in other countries, such as Denmark, Germany, and USA, for various studies providing a better understanding of the barley genome. The collection will be immensely valuable for future molecular genetical analyses of clone mutant genes. (author)

  10. Diagnosis and treatment of gastroesophageal reflux disease

    Badillo, Raul; Francis, Dawn

    2014-01-01

    Gastroesophageal reflux disease (GERD) is a common disease with a prevalence as high as 10%-20% in the western world. The disease can manifest in various symptoms which can be grouped into typical, atypical and extra-esophageal symptoms. Those with the highest specificity for GERD are acid regurgitation and heartburn. In the absence of alarm symptoms, these symptoms can allow one to make a presumptive diagnosis and initiate empiric therapy. In certain situations, further diagnostic testing is needed to confirm the diagnosis as well as to assess for complications or alternate causes for the symptoms. GERD complications include erosive esophagitis, peptic stricture, Barrett’s esophagus, esophageal adenocarcinoma and pulmonary disease. Management of GERD may involve lifestyle modification, medical therapy and surgical therapy. Lifestyle modifications including weight loss and/or head of bed elevation have been shown to improve esophageal pH and/or GERD symptoms. Medical therapy involves acid suppression which can be achieved with antacids, histamine-receptor antagonists or proton-pump inhibitors. Whereas most patients can be effectively managed with medical therapy, others may go on to require anti-reflux surgery after undergoing a proper pre-operative evaluation. The purpose of this review is to discuss the current approach to the diagnosis and treatment of gastroesophageal reflux disease. PMID:25133039

    Upper gastrointestinal endoscopy and radiologic examination were performed in 101 patients with symptoms strongly suggestive of gastroesophageal reflux (GER) disease. Hiatus hernia (HH) was found in 50 patients diagnosed by radiography or endoscopy, or both, in 22, 19, and 9 patients respectively. Severe endoscopic esophagitis (grades III and IV) was found more often (p<0.05) in the patients with HH than in those without. The same was true for the early positive timed acid perfusion tests (p<0.02). Furthermore, the patients with HH more often had reflux by the standard acid reflux test (42 og 50 versus 28 of 51; p<0.01), gastroesophageal scintigraphy (47 of 50 versus 40 of 51; p<0.05), and radiography (20 of 50 versus 2 of 51; p<0.001) than the patients without HH. The results show that severe GER disease can occur without an associated HH and indicate that patients with symptoms of GER disease and associated HH are likely to have a more severe GER disease than those without HH

    In order to evaluate the possibility of detecting intra-renal reflux (IRR) with a more sensitive procedure, 48 children with recurrent urinary tract infections underwent intravenous urography (IVU) and voiding cystourethrogram (VCU) using a solution containing contrast medium and sup(99m)Tc-sulfur colloid particles which are known to persist in the renal parenchyma for a long time. Scintigraphic images were taken at 5 and 20 hours after VCU. 18 children had no vesico-ureteral reflux, 11 showed unilateral and 19 bilateral VUR, which was therefore present in 49 renal units. Among the 49 renal refluxing units (RRUs) IRR was detected radiologically in 8; of these isotopic activity in the renal area was present in all 6 RRUs who were examined at 20 hours. Of the remaining 41 RRUs with no radiologically detectable IRR 24 were evaluated at 20 hours and 5 (21%) showed renal radioactivity. Renal scars were significantly more frequent in kidneys with radioisotopic activity at 20 hours. The results of this study indicate that radionuclide cystography using sup(99m)Tc-sulfur colloid is a reliable procedure for demonstrating IRR, and to this end is more sensitive than X-ray VCU. Radionuclide cystography with sulfur colloid particles should therefore be considered a simple and useful complementary procedure, which is more sensitive than X-ray VCU in the diagnosis and follow-up of IRR

New projects are planned for studies of auroral electrodynamics using high altitude rockets, investigations of noctilucent clouds, and active release experiments. These will require increased technical capabilities with respect to payload design, rocket performance and ground support as compared with the current program. Coordination with EISCAT and the planned Viking satellite is essential for the future projects. (Auth.)

    The prevalence of gastroesophageal reflux disease (GERD) has mirrored the increase in obesity, and GERD is now recognized as an obesity-related comorbidity. There is growing evidence that obesity, specifically central obesity, is associated with the complications of chronic reflux, including erosive esophagitis, Barrett's esophagus, and esophageal adenocarcinoma. While fundoplication is effective in creating a competent gastroesophageal junction and controlling reflux in most patients, it is less effective in morbidly obese patients. In these patients a bariatric operation has the ability to correct both the obesity and the abnormal reflux. The Roux-en-Y gastric bypass is the preferred procedure.

    The Gastroesophageal Reflux Disease has a prevalence of ∼12% of the urban population in Brazil. Koufman proposed the term to designate Laryngeal Pharyngeal Reflux (LPR) symptoms, signs or tissue damage resulting from aggression of the gastrointestinal contents in the upper aerodigestive tract. Belafsky et al proposed a score that points to inflammatory laryngeal signs through videolaryngoscopic findings, the Reflux Finding Score (RFS). Moreover, in 2002, they published the Reflux Symptom Index (RSI). The objective of this study is to provide a comparison between the Reflux Finding Score and the Reflux Symptom Index in the practice of Otorhinolaryngology. Our study involved a total of 135 patients who visited the Ear, Nose, and Throat (ENT) clinic Núcleo de Otorrinolaringologia e Cirurgia de Cabeça e Pescoço de São Paulo between April 2014 and May 2015 with suspected LPR. We excluded nine patients and the study group was 126 patients. All patients were ranked by their RSI and RFS scores. The study group consisted of 126 patients (88 women and 38 men). Their main complaints were cough (40.4%), globus (21.4%), dysphonia (19.8%), throat clearing (15.8%), postnasal drip (3.17%), snoring (1.5%), dysphagia (1.5%), cacosmia (0.7%), and regurgitation (1.5%). The RSI ranges from 13 to 42 with a mean of 20.7 (SD = 6.67). The RFS ranged from 3 to 19 with a mean of 9.53 (SD = 2.64). The RSI and RFS can easily be included in ENT routines as objective parameters, with low cost and high practicality. Based on the clinical index, the specialist can evaluate the need for further tests.

    Gastroesophageal reflux disease is one of the most common comorbidities in patients with asthma. Gastroesophageal reflux disease can be linked to difficult-to-control asthma. Current management includes gastric acid suppression therapy and surgical antireflux procedures. The LINX® procedure is a novel surgical treatment for patients with gastroesophageal reflux disease refractory to medical therapy. To the best of our knowledge, we report the first case of successful treatment of refractory asthma secondary to gastroesophageal reflux disease using the LINX® procedure. Our patient was a 22-year-old white woman who met the American Thoracic Society criteria for refractory asthma that had remained poorly controlled for 5 years despite progressive escalation to step 6 treatment as recommended by National Institutes of Health-National Asthma Education and Prevention Program guidelines, including high-dose oral corticosteroids, high-dose inhaled corticosteroid plus long-acting β2-agonist, leukotriene receptor antagonist, and monthly omalizumab. Separate trials with azithromycin therapy and roflumilast did not improve her asthma control, nor did bronchial thermoplasty help. Additional consultations with two other university health systems left the patient with few treatment options for asthma, which included cyclophosphamide. Instead, the patient underwent a LINX® procedure after failure of maximal medical therapy for gastroesophageal reflux disease with the additional aim of improving asthma control. After she underwent LINX® treatment, her asthma improved dramatically and was no longer refractory. She had normal exhaled nitric oxide levels and loss of peripheral eosinophilia after LINX® treatment. Prednisone was discontinued without loss of asthma control. The only immediate adverse effects due to the LINX® procedure were bloating, nausea, and vomiting. LINX® is a viable alternative to the Nissen fundoplication procedure for the treatment of patients with

    The prevalence of gastroesophageal reflux disease (GERD) symptoms has not been investigated in patients on maintenance hemodialysis in Japan, and few studies have reported the effect of proton pump inhibitors (PPIs) in hemodialysis patients with GERD symptoms. Here, we investigated the prevalence of GERD symptoms and the effects of the PPI esomeprazole on the quality of life related to reflux and dyspepsia in patients on maintenance hemodialysis. This was a cross-sectional/cohort study of hemodialysis outpatients implemented in 10 Japanese medical facilities from October 2012 to March 2014. The trial was registered in the UMIN Clinical Trial Registry (UMIN000009124). Forty-one of 385 patients (11%) reported GERD symptoms on the Global Overall Symptom (GOS) questionnaire. Multivariate logistic regression analysis identified the independent prognostic factors for GERD symptoms as a history of gastric ulcer and use of sevelamer hydrochloride or calcium polystyrene sulfonate. Participants with GERD symptoms completed the Quality of Life in Reflux and Dyspepsia, Japanese version (QOLRAD-J) questionnaire and were assigned to receive 4-week esomeprazole treatment (20 mg/day). This PPI therapy significantly improved all QOLRAD-J domains in the full analysis set (n = 28) and improved the GERD symptoms listed in the GOS questionnaire. Significantly impaired disease-specific quality of life (QOL) in the QOLRAD-J domains was observed in 44.4-74.1% of patients who had symptoms before treatment. The mean GOS and QOLRAD-J scores correlated significantly. Therapy with 20 mg/day esomeprazole appears to be efficacious for improving disease-specific QOL and GERD symptoms in Japanese patients on maintenance hemodialysis.

    The aim of this work was to study the correlation between the reflux timing and the presence of esophagitis, an inconstant but serious complication of gastro-esophageal reflux (GER). The hypothesis was that reflux occurring late after meal can be incriminated more than early reflux in esophagitis genesis. 32 children with GER (mean age = 10.5 months, 2 to 30 months) had esophagoscopy and scintigraphy in the same week. The children were classified in two groups according to esophagoscopy: group 1 (n = 18) no esophagitis, group 2 (n = 14) esophaqgitis. The scintigraphy involved the ingestion of 0.5 mCi Tc-99m sulfur colloid milk mixture, followed by esophageal and gastric activity recording (one image per minute for 1 hour). The reflux was assessed from contrast enhanced images and esophageal time activity curves. Reflux intensity was quantitated by reflux index (Re). Mean reflux time was calculated as the mean esophageal activity peaks time (t-bar). Finally a composite parameter was calculated as the mean reflux time weighted by the relative intensity of each reflux peak (t-barw). Re was not found to be different between the two groups. t-bar was significantly higher in group 2: t-bar = 29.6 +- 3.0 mn (mean +- SD) than in group 1: t-bar = 24.5 +- 6.8 mn; rho <0.02. The difference between the two groups was enhanced by intensity weighting: group 1: t-barw = 16.6 +- 6.3 mn, group 2: t-barw = 33.5 +- 7.1 mn rho <0.001. t-barw value was not correlated to esophagitis grade. These results suggest that late reflux is more likely responsible of esophagitis

    Supraesophageal reflux of gastric contents can contribute to perennial nasopharyngitis, cough, and asthma. However, effective treatment strategies for supraesophageal reflux disease (SERD) remain inadequately defined. The purpose of this study is to assess the prevalence and timing of SERD and to investigate the efficacy of head-of-bed elevation in its treatment. A retrospective chart review of patients seen at Scripps Clinic Division of Allergy, Asthma and Immunology was performed who had undergone overnight nasopharyngeal pH monitoring with a commercially available nasopharyngeal pH-monitoring device, Dx-pH Measurement System from Restech, San Diego, Calif. Subjects with reflux were classified based on the position of reflux as either supine only, upright only, or both supine and upright. In a subset of subjects with supine-only reflux, pH monitoring was compared before and after elevating the head of bed 6 inches. Adequate nasopharyngeal pH-monitoring data were obtained for 235 patients. Reflux was detected in 113 (48%) patients. The pattern of reflux observed was 62 (55%) supine only, 4 (4%) upright only, and 47 (42%) upright and supine. Sequential overnight nasopharyngeal pH monitoring before and after head-of-bed elevation was obtained in 13 individuals with supine-only reflux. Ten subjects demonstrated significant improvement, 8 of whom demonstrated complete resolution of supine reflux with 6 inches of head-of-bed elevation. This study provides new evidence that SERD frequently occurs in the supine position and that 6 inches of head-of-bed elevation is effective in reducing supine SERD.

    Gastro-oesophageal reflux (GOR) is common in infants, and feed thickeners are often used to manage it in infants as they are simple to use and perceived to be harmless. However, conflicting evidence exists to support the use of feed thickeners. To evaluate the use of feed thickeners in infants up to six months of age with GOR in terms of reduction in a) signs and symptoms of GOR, b) reflux episodes on pH probe monitoring or intraluminal impedance or a combination of both, or c) histological evidence of oesophagitis. We used the standard search strategy of the Cochrane Neonatal Review Group to search the Cochrane Central Register of Controlled Trials (CENTRAL 2016, Issue 2), MEDLINE via PubMed (1966 to 22 November 2016), Embase (1980 to 22 November 2016), and CINAHL (1982 to 22 November 2016). We also searched clinical trials databases, conference proceedings, and the reference lists of retrieved articles for randomised controlled trials. We included randomised controlled trials if they examined the effects of feed thickeners as compared to unthickened feeds (no treatment or placebo) in treating GOR in term infants up to six months of age or six months of corrected gestational age for those born preterm. Two review authors independently identified eligible studies from the literature search. Two review authors independently performed data extraction and quality assessments of the eligible studies. Differences in opinion were resolved by discussion with a third review author, and consensus was reached among all three review authors. We used the GRADE approach to assess the quality of the evidence. Eight trials recruiting a total of 637 infants met the inclusion criteria for the systematic review. The infants included in the review were mainly formula-fed term infants. The trials were of variable methodological quality. Formula-fed term infants with GOR on feed thickeners had nearly two fewer episodes of regurgitation per day (mean difference -1.97 episodes per day

    Abstract Background: Laparoscopic Nissen fundoplication (LNF) has been the gold standard for the surgical management of Gastro-esophageal reflux disease (GERD). Laparoscopic anterior 180° fundoplication (180° LAF) is reported to reduce the incidence of postoperative complications while obtaining similar control of reflux. The present meta-analysis was conducted to confirm the value of the 2 techniques. Methods: PubMed, Medline, Embase, Cochrane Library, Springerlink, and China National Knowledge Infrastructure Platform databases were searched for randomized controlled trials (RCTs) comparing LNF and 180° LAF. Data regarding the benefits and adverse results of 2 techniques were extracted and compared using a meta-analysis. Results: Six eligible RCTs comparing LNF (n = 266) and 180° LAF (n = 265) were identified. There were no significant differences between LNF and 180° LAF with regard to operating time, perioperative complications, length of hospital stay, patient satisfaction, willingness to undergo surgery again, quality of life, postoperative heartburn, proton pump inhibitor (PPI) use, postoperative DeMeester scores, postoperative lower esophageal sphincter (LES) pressure, postoperative gas-bloating, unable to belch, diarrhea, or overall reoperation. LNF was associated with a higher prevalence of postoperative dysphagia compared with 180° LAF, while 180° LAF was followed by more reoperation for recurrent reflux symptoms. Conclusion: LNF and 180° LAF are equally effective in controlling reflux symptoms and obtain a comparable prevalence of patient satisfaction. 180° LAF can reduce the incidence of postoperative dysphagia while this is offset by a higher risk of reoperation for recurrent symptoms. The risk of recurrent symptoms should need to be balanced against the risk of dysphagia when surgeons choose surgical procedures for each individual with GERD. PMID:28906412

    The prokinetic agent cisapride is effective for the treatment of gastroesophageal reflux disease (GERD) in infants and children, but is no longer used for this purpose because of safety concerns. Therefore, other pharmacological agents need to be investigated for efficacy in GERD treatment. In this study, we examined the effectiveness and safety of mosapride for the treatment of neurologically impaired children and adolescents with GERD. Mosapride (0.3 mg/kg/day) was administered to 11 neurologically impaired patients with GERD (five male; median age, 12.3 years). Esophageal acid exposure was measured using esophageal pH monitoring before and at >5 days after the start of mosapride treatment. The pressure and length of the lower esophageal sphincter were compared before and after mosapride treatment. In the 11 patients, median reflux index (percentage of the total monitoring period during which recorded pH was reflux (range, 0.5-2.1 min/reflux) before and 0.7 min/reflux (range, 0.4-1.2 min/reflux) after treatment with mosapride (P = 0.02). The median number of reflux episodes before (219) and after (122) drug treatment did not differ significantly. The decreased reflux index in neurologically impaired patients with GERD is due to mosapride, therefore mosapride may be a candidate for GERD treatment. © 2016 Japan Pediatric Society.

    Helicobacter pylori is associated with gastritis, peptic ulcers and gastric malignancies. Little attention has been paid to the possibility that it may also have a role in the pathogenesis of reflux oesophagitis. This is especially true in elderly patients who have life-long infection and provide an ideal group to study the mucosal changes associated with the organism. The aim of this study was to determine if H pylori is associated with reflux oesophagitis in elderly patients. Consecutive gastroscopy patients were recruited. Multiple biopsies were taken from oesophagus, stomach, antrum and duodenum for histology and rapid urease tests. Patients also had IgG ELISA antibodies and 13C-urea breath tests performed. Patients with macroscopic or microscopic evidence of reflux oesophagitis were compared to patients with macroscopically normal upper gastrointestinal tracts and no microscopic evidence of reflux. A total of 114 patients were recruited, average age 78.9 years (+/- 5.4). There were 37 refluxers and 33 non-refluxers. We found no evidence for an association between the presence of H pylori and reflux oesophagitis in elderly patients. The high prevalence of H pylori in patients with reflux oesophagitis can be explained by the presence of incidental gastritis. PMID:8733530

    To determine whether a pH probe or multichannel intraluminal impedance (MII) more frequently detected gastro-oesophageal reflux and test the hypothesis that acid reflux was associated with lower baseline impedance. A prospective study of infants in whom reflux was suspected and evaluated using combined pH and multichannel impedance. Studies were considered abnormal if the acid index was >10% or there were >79MII reflux events in 24 hours. The acid index was the percentage of total study time with a pHacid clearance time (ACT) the time from the pH falling below four to rising above four. Forty-two infants [median gestational age 31 (range 23-42) weeks] were assessed. Only nine infants (21%) had abnormal studies, seven detected by pH monitoring, one by MII monitoring and one by both techniques (p = 0.04). After correcting for gestational age and post-natal age, baseline impedance remained negatively correlated with the acid index (r = -0.34, p = 0.038) and the maximum ACT (r = -0.44, p = 0.006). Clinical suspicion of reflux was frequently incorrect, and reflux was more frequently detected by a pH probe. The inverse relationship of acid reflux to baseline impedance suggests that mucosal disruption may result from acid reflux in this population. ©2018 Foundation Acta Paediatrica.

    Asthma and recurrent bronchopneumopathies in children are often associated with gastroesophageal reflux. Cine-esogastroscintigraphy is proposed for demonstrating reflux and establishing its direct or indirect responsibility in respiratory disease. 133 patients aged 5 months to 16 years were studied. Reflux was found in 65.5% of cases, either severe (44.4% of cases) or minor (21.1%). Episodes of reflux produced respiratory manifestations in 7% of patients. Inhalation of refluxed material was proved in 3% by demonstration of pulmonary contamination. Sensitivity of cine-esophagogastroscintigraphy is comparable to that of esophageal pH measurement for detection of reflux. It does not require positioning of a probe in the esophageal lumen. It provides quantitative parameters on esophageal transit, reflux and gastric voiding, and demonstrates pulmonary contamination. It is easy to perform and can be readily included in an outpatient clinic workup. Its sensitivity and reliability make it a useful tool for evaluation of therapeutic efficiency. The interlocking of various physiopathologic factors contributes to the polymorphism of respiratory manifestations of reflux.

    Development from chronic inflammation to Barrett's adenocarcinoma is known as one of the inflammation-related carcinogenesis routes. Gastroesophageal reflux disease induces regurgitant esophagitis, and esophageal mucosa is usually regenerated by squamous epithelium, but sometimes and somewhere replaced with metaplastic columnar epithelium. Specialized columnar epithelium, so-called Barrett's epithelium (BE), is a risk factor for dysplasia and adenocarcinoma in esophagus. Several experiments using rodent model inducing duodenogastroesophageal reflux or duodenoesophageal reflux revealed that columnar epithelium, first emerging at the proliferative zone, progresses to dysplasia and finally adenocarcinoma, and exogenous carcinogen is not necessary for cancer development. It is demonstrated that duodenal juice rather than gastric juice is essential to develop esophageal adenocarcinoma in not only rodent experiments, but also clinical studies. Antireflux surgery and chemoprevention by proton pump inhibitors, nonsteroidal anti-inflammatory drugs, selective cyclooxygenase-2 inhibitors, green tea, retinoic acid and thioproline showed preventive effects on the development of Barrett's adenocarcinoma in rodent models, but it remains controversial whether antireflux surgery could regress BE and prevent esophageal cancer in clinical observation. The Chemoprevention for Barrett's Esophagus Trial (CBET), a phase IIb, multicenter, randomized, double-masked study using celecoxib in patients with Barrett's dysplasia failed to prove to prevent progression of dysplasia to cancer. The AspECT (Aspirin Esomeprazole Chemoprevention Trial), a large multicenter phase III randomized trial to evaluate the effects of esomeprazole and/or aspirin on the rate of progression to high-grade dysplasia or adenocarcinoma in patients with BE is now ongoing

    This paper discusses different gender aspects of the Swedish Armed Forces with specific references to sexual harassment and prostitution. By using the concept of Hegemonic Masculinity, sexual harassment of the women in the Swedish Armed Forces is explained in terms of a need of the men within...... the organisation to reinforce the notion of women as inferior and subordinate to men, whereby the external hegemony is believed to be restored. Likewise, male Swedish peacekeepers’ demand for prostitution during international peacekeeping missions is explained in terms of a need to confirm manhood and as homo...

  1. Esophageal Mucosal Impedance Pattern is Distinct in Patients With Extraesophageal Reflux Symptoms and Pathologic Acid Reflux.

    Current diagnostic tests for gastroesophageal reflux disease (GERD) do not consistently measure chronicity of reflux. Mucosal impedance (MI) is a minimally invasive measurement to assess esophageal conductivity changes due to GERD. We aimed to investigate MI pattern in patients with symptoms of extraesophageal reflux (EER) in a prospective longitudinal cohort study. Patients with potential symptoms of EER undergoing esophagogastroduodenoscopy (EGD) with wireless pH monitoring were studied. Participants included those with erosive esophagitis (E+), normal EGD/abnormal pH (E-/pH+), and normal EGD/normal pH (E-/pH-). MI was measured from the site of injury in patients with E+, as well as at 2, 5, and 10 cm above the squamocolumnar junction (SCJ) in all participants. Forty-one patients with symptoms of EER were studied. MI measurements at 2 cm above the SCJ were significantly (P = 0.04) different among the three groups, with MI lowest for E+ and greatest for E-/pH- patients. Although not statistically significant, there is a graded increase in median (interquartile range) MI axially along the esophagus at 5 cm (P = 0.20) and at 10 cm (P = 0.27) above the SCJ, with those with reflux (E+ and E-/pH+) having a lower MI than those without. Patients with symptoms of EER and evidence of acid reflux have an MI lower than those without at 2 cm above the SCJ, with a trend at 5 cm and 10 cm as well. MI may be a tool to assess presence of GERD in patients presenting with EER symptoms. Copyright © 2017 The Voice Foundation. Published by Elsevier Inc. All rights reserved.

  2. Diagnostic tests in gastroesophageal reflux disease (GERD)

    The true prevalence of gastroesophageal reflux disease (GERD) is difficult to establish despite that an estimated 11% of the U.S. population experiencing heartburn daily or 30% every three days (1), perhaps due to that the disease can cause many symptoms, both typical and atypical as heartburn or chest pain, among others. Multiple techniques for measuring reflux have been used, and many authors (1-3) have asked why this situation, possibly because the techniques measure and quantify the basic pathophysiologic problem disease, the time of exposure of the esophagus distal to the gastric juice, because the measures are quantitatively related to the degree of esophageal mucosal injury, or because the episodes of exposure to gastric juice correlated with the patient's symptoms. As said Richter (4) m any times these studies are unnecessary because the history is sufficiently revealing to identify the presence of GERD. But the clinician must decide which test you choose to carry a diagnosis of a reliable, timely and cost-effective . But we cannot rely on the presence of symptoms to diagnosis, because we incur the overdiagnosis in a considerable number of individuals, the sensitivity set for the typical symptoms as heartburn is 68% and specificity was 63% (2), which leads us to conclude that atypical symptoms should be investigated as they may relate to functional dyspepsia rather than GERD. It is also clear that the severity and frequency of symptoms in any way correlates with the presence or absence of esophagitis, patients with erosive esophagitis are more severe disease and increased risk of developing complications. The persistent exposure of the esophagus to gastric juice does not cause mucosal injury in all individuals, therefore, it is possible to define the disease by the presence of mucosal injury, while endoscopy is able to define the mucosal injury caused by the reflux can also lead to false conclusions, such as those patients with symptoms of GERD who have no

    The therapeutical approach to vesicoureteral reflux (VUR) depends on assessment of the renal involvement. The effective renal plasma flow (ERPF) and parenchymal mean transit time of radiotracer (pMTT) of the affected kidney are sensitive functional parameters. We investigated the association of these functional indices with the volume of refluxed urine. In 64 children (mean age 6.4 yrs) the presence of VUR was confirmed with direct radionuclide cystography in 80 ureters (48 unilateral and 32 bilateral) and the maximal volume of refluxed urine (MVRU) was determined for each uretero-renal unit. All patients also underwent dynamic renal scintigraphy with I-131-hippuran, providing the values of pMTT and relative renal hippuran clearances of the respective kidneys by deconvolution analysis. In 37 of the affected kidneys ERPF was also determined by combining the latter results with total ERPF, determined by plasma clearance of hippuran. Using the borderline value of MVRU of 4 ml, the group with higher MVRU exhibited significantly lower ERPF of the affected kidney (194±93 vs. 270±77 ml/min/1.73 m2, p=.002) and significantly higher proportion of pMTT's over 3.5 min (31/33 vs. 17/47, p=.003). The negative linear correlation between MVRU and ERPF was found (r=-.45, p=.006). We conclude that quantitative radionuclide cystography, aside from diagnosis and follow-up of VUR, may also provide insight in the function of the affected kidney and thus contribute in designing the therapeutical approach.

  4. Role of endoscopy in gastroesophageal reflux disease

    2015-01-01

    Full Text Available Gastroesophageal reflux disease is a condition due to reflux of stomach content in the esophagus causing trouble symptoms or complications or both. GERD is a clinical diagnosis and typically presents with a heartburn and/or regurgitation and a positive response to antacid secretory medications. GERD is the leading outpatient diagnosis among all gastrointestinal disorders in the United States. Approximately 40% of population report occasional symptoms of GERD whereas 10-20% of patients will have symptoms at least once in a week. Recent guidelines from gastrointestinal societies such as American College of Gastroenterology, American Society for Gastrointestinal Endoscopy and American College of Physicians have laid out specific indications regarding role of esophagogastroduodenoscopy in GERD. Despite these recommendations, studies have revealed that one-fifth to two-fifth EGDs may not be clinically indicated, especially where open access endoscopy referral system is used. Traditionally, GERD has been thought to be a disease of the western world. Prevalence rates had been estimated to be lower in Asia when compared to that of the Western Countries. Few recent epidemiological studies in India showed the prevalence of reflux disease in India to be between 8-24%, which is comparable to the western world. The use of EGDs becomes more critical for developing countries such as India where prevalence of GERD and BE is comparable to the western countries but have limited resources. In addition to direct cost for an EGD, it burdens economy with indirect costs such as time off from the work, transportation and any procedural complications. Risk stratifying patients with GERD may therefore prevent unnecessary procedures, harms and costs. The aim of this paper is to review the existing evidence on the role of endoscopy in GERD.

    Bile reflux may occur after a variety of reconstructive procedures in the gastro-intestinal tract and biliary system. The present paper deals with reflux into the duodenum, jejunum, stomach, oesophagus and into blind loops. The demonstration of reflux by sup(99m)Tc labelled IDA acid derivatives, and a possible quantitative approach, are discussed. The advantages of isotope methods are: 1. Direct demonstration of bile reflux without any intervention in the physiological process and with little trouble to the patient. 2. The ability to use the method for various reconstructive procedures and 3. the additional information obtained which may help in the differential diagnosis of blind loops, biliary obstruction, cholecystitis or liver metastases if there has been a gastrectomy for a malignant tumour. In combination with a second administration of a radio-isotope tracer, one may be able to demonstrate abnormalities in the motility of the stomach or gut, or pyloric stenosis or gastro-oesophageal reflux.

    Gastro-oesophageal reflux disease (GORD) develops when reflux of gastric content causes troublesome symptoms or complications. The main symptoms are heartburn and acid regurgitation and complications include oesophagitis, strictures, Barrett's oesophagus and oesophageal adenocarcinoma. In addition to hereditary influence, GORD is associated with lifestyle factors, mainly obesity. Tobacco smoking is regarded as an aetiological factor of GORD, while alcohol consumption is considered a triggering factor of reflux episodes and not a causal factor. Yet, both tobacco smoking and alcohol consumption can reduce the lower oesophageal sphincter pressure, facilitating reflux. In addition, tobacco smoking reduces the production of saliva rich in bicarbonate, which is important for buffering and clearance of acid in the oesophagus. Alcohol also has a direct noxious effect on the oesophageal mucosa, which predisposes to acidic injury. Tobacco smoking cessation reduces the risk of GORD symptoms and avoidance of alcohol is encouraged in individuals where alcohol consumption triggers reflux. Copyright © 2017 Elsevier Ltd.

  7. Proton Pump Inhibitors in Gastroesophageal Reflux Disease: Friend or Foe.

    2017-09-01

    Proton pump inhibitor (PPI) use in gastroesophageal reflux disease (GERD) has been redefined, in light of recent advances highlighting GERD phenotypes that respond to PPIs, and fresh revelations of potential risks of long-term PPI therapy. Erosive esophagitis predicts excellent response to PPI therapy, but non-erosive reflux disease (NERD) with abnormal reflux parameters on ambulatory reflux monitoring also demonstrates a similar response. In contrast, response is suboptimal in the absence of abnormal reflux parameters. In this setting, if an alternate appropriate indication for PPI therapy does not coexist, risks may outweigh benefits of PPI therapy. Adverse events from long-term PPI therapy continue to be reported, most based on association rather than cause-and-effect. Appropriate indications need to be established before embarking on long-term PPI therapy. Future research will define true risks of long-term PPI therapy, and develop alternate management options for acid peptic diseases.

    Thirty-six (36) patients with symptomatic gastroesophageal reflux were studied. Symptoms of heartburn, regurgitation, and dysphagia were scored as to their severity and compared to quantitative tests of gastroesophageal reflux. Patients were studied with the acid reflux test, fiberoptic endoscopy, exophageal mucosal biopsy with a pinch forceps, esophageal manometry, and radioisotopic gastroesophgeal scintigraphy. Symptoms were scored according to an arbitrary grading system as mild, moderate, or severe. There were significant correlations between symptoms scores and both the degree of endoscopic esophagitis and the gastroesophageal reflux indices as measured by the radioisotopic scintiscan, but not with the degree of histologic esophagitis or lower esophageal sphincter pressure. Review of the findings suggest the following profile for patients who might require antireflux surgery: severe symptoms; presence of endoscopic esophagitis; resting lower esophageal sphincter pressure below 10 mmHg; and gastroesophageal reflux index above 10%

    To study the correlation of obstructive sleep apnoea (OSA) and laryngopharyngeal reflux (LPR). A descriptive study. Suez Canal University Hospital, Ismailia, Egypt. 62 patients with polysomnography confirmed OSA. Patients were evaluated with ambulatory 24-h double channel pH monitoring. Mean reflux symptom index in the study group was 9 ± 5.5, and it was > 13 in all patients with severe OSA. Signs of LPR reflux were present in 34 (55%) patients. Abnormal reflux was detected in the distal oesophagus in 41 patients (66%) and in the proximal oesophagus in 21 patients (34%). Patients with severe OSA had significantly higher nocturnal LPR reflux episodes compared to patients with mild disease (P .05). LPR is common in patients with OSA. Patients with severe OSA have significantly higher nocturnal LPR. This should be considered when treating this group of patients. © 2016 John Wiley & Sons Ltd.

  10. The Swedish wood fuel market

    In Sweden, wood fuels are traditionally used in the Swedish forest products industry and for heating of single-family houses. More recently they are also become established as an energy source for district heating and electricity production. Energy policy, especially the energy taxation system, has favoured wood fuels and other biofuels, mainly for environmental reasons. There is now an established commercial market for wood fuels in the district heating sector, which amounts to 45 PJ and is growing 20 per cent annually. Price levels have been stable in current prices for a decade, mainly because of good access to wood fuels. Price levels are dominated by production costs on a market that is largely governed by the buyer. It is expected that the use of wood fuels will increased in Sweden in the future, which will push a further development of this section on the market and bring about technological changes in the area.

    I very much enjoyed reading Jim Fleming’s article on Carl-Gustaf Rossby and the seminal contributions Rossby made to meteorology. Furthermore, the otherwise excellent article has two errors. Something must have gotten lost in translation to cause Fleming to claim that “Rossby pursued numerical weather prediction in Sweden in an era in which there was no Swedish word for digital computer.” With applied mathematician Germund Dahlquist, Rossby developed a weather model for the Binär Elektronisk Sekvens Kalkylator (BESK; Binary Electronic Sequence Calculator). Designed and built in Sweden, BESK was the world’s fastest computer when it became operational in 1953. From September 1954, BESK weather simulations enabled routine 24-hour national forecasts.

  12. Studies in Swedish Energy Opinion

    the 1970s, energy production was politicized big time in the industrialized world. The birth of the environmental movement, the oil crises in 1973 - 74 and the beginning conflict surrounding civilian nuclear power, put energy issues center stage on the political agenda. Energy policies - especially related to the development of nuclear power - came to dominate election campaigns, like in Sweden in 1976 or be the subject of referendums, like in Austria in 1978 or in Sweden in 1980. Critical voices toward the peaceful use of nuclear power - having started in America before being exported to Europe - gained real strength and public support all over the Western world by the nuclear accident at the Three Mile Island plant in Harrisburg, Pennsylvania in 1979. The energy genie was out of the bottle and out to stay. Fueled by the nuclear meltdowns in Chernobyl in 1986 and in Fukushima in 2011 and supplemented by conflicts over how to reduce the use of oil and coal, how to sensibly exploit the waste gas reserves, and how to develop renewable energy sources based on sun, wind and waves – have made all kinds of energy issues the focal point of political contentions ever since the early 1970s. In Sweden, as in many other countries, energy policies - often with nuclear power in the center - have been one of the most fought-over policy areas during the last thirty-forty years. And the contentious character of energy policies is not limited to the elite level of politics - to politicians, to media pundits or to lobbyists. It is also manifest among ordinary citizens. Energy issues - nuclear power and wind power in particular - are highly polarizing among voters as well.

    Full Text Available Abstract Background Our aim in the present study was to compare patients presenting with gastroesophageal reflux disease in the presence or absence of mild-grade esophagitis (grade I or II according to the Savary-Miller classification. Methods Between 2005 and 2007, 215 patients with gastroesophageal reflux disease (67 with reflux associated with grade I or II esophagitis and 148 without esophagitis were evaluated at the Department of Surgery, University Hospital Tor Vergata, Rome, and were included in the present study. The evaluations consisted of clinical interviews, endoscopy of the high digestive tract, esophageal manometry and pH monitoring. Results There was no significant difference between the two groups with regard to age, sex or symptoms. The incidence of heartburn associated with noncardiac chest pain was greater in the esophagitis group than in the dysphagia group. The incidence of hiatal hernia was similar in both groups. Although the motor pattern was similar in both groups, the length of the abdominal esophagus was greater in patients without esophagitis (1.6 cm vs 1.1 cm; P  Conclusions Gastroesophageal reflux without esophagitis must be regarded not as a milder form of the disease but as part of a single disease. Furthermore, these patients often demonstrate lower rates of symptom improvement after antireflux treatment in comparison with patients with erosive esophagitis. Therefore, further trials to assess the treatment algorithm for these patients are warranted.

  14. Biomass and Swedish energy policy

    International Nuclear Information System (INIS)

    2001-01-01

    The use of biomass in Sweden has increased by 44% between 1990 and 1999. In 1999 it was 85 TWh, equivalent to 14% of the total Swedish energy supply. The existence of large forest industry and district heating systems has been an essential condition for this expansion. The tax reform in 1991 seems, however, to have been the most important factor responsible for the rapid bioenergy expansion. Through this reform, the taxation of fossil fuels in district heating systems increased by approximately 30-160%, depending on fuel, whereas bioenergy remained untaxed. Industry is exempted from the energy tax and pays reduced carbon tax. No tax is levied on fossil fuels used for electricity production. Investment grants have existed for biomass-based electricity production but these grants have not been large enough to make biomass-based electricity production economically competitive in a period of falling electricity prices. Despite this, the biomass-based electricity production has increased slightly between 1990 and 1999. A new taxation system aiming at a removal of the tax difference between the industry, district heating and electricity sectors has recently been analysed by the Swedish government. One risk with such a system is that it reduces the competitiveness for biomass in district heating systems as it seems unlikely that the taxes on fossil fuels in the industry and electricity sectors will increase to a level much higher than in other countries. A new system, based on green certificates, for supporting electricity from renewable energy sources has also been proposed by the government.

    The most common extraesophageal manifestations of gastroesophageal reflux disease (GERD) include chronic cough, asthma and laryngitis. There are two mechanisms proposed to explain extraesophageal syndromes caused by GERD. The first one is a direct way via irritation and/or microaspiration and the second one is an indirect, vagally mediated way. The investigation of extraesophageal manifestations of GERD is difficult and the empirical therapy with proton pump inhibitors usually double dose for at least three months is still the most common approach.

    To assess an effectiveness of surgical treatment of gastroesophageal reflux disease (GERD) combined with hiatal hernia (HH). The trial included 96 patients with GERD and HH who were divided into 2 groups. The principal difference between groups was the use of surgery in the main group and therapeutic treatment in the comparison group. The effectiveness of surgical treatment is superior to therapeutic treatment of GERD by more than 2.5 times. HH combined with GERD is an indication for surgical treatment.

    This prospective multicenter investigation was conducted to define the repeatability of duplex-based identification of venous reflux and the relative effect of key parameters on the reproducibility of the test. Repeatability was studied by having the same technologist perform duplicate tests, at the same time of the day, using the same reflux-provoking maneuver and with the patient in the same position. Reproducibility was examined by having two different technologists perform the test at the same time of the day, using the same reflux-provoking maneuver and with the patient in the same position. Facilitated reproducibility was studied by having two different technologists examine the same patients immediately after an educational intervention. Limits of agreement between two duplex scans were studied by changing three elements of the test: time of the day (morning vs afternoon), patient's position (standing vs supine), and reflux initiation (manual vs automatic compression-decompression). The study enrolled 17 healthy volunteers and 57 patients with primary chronic venous disease. Repeatability of reflux time measurements in deep veins did not significantly differ with the time of day, the patient's position, or the reflux-provoking maneuver. Reflux measurements in the superficial veins were more repeatable (P ultrasound detection of venous reflux. Reports should include information on the time of the test, the patient's position, and the provoking maneuver used. Adopting a uniform cut point of 0.5 second for pathologic reflux can significantly improve the reliability of reflux detection. Implementation of a standard protocol should elevate the minimal standard for agreement between repeated tests from the current 70% to at least 80% and with more rigid standardization, to 90%.

    To evaluate the diagnosis and management of reflux and gastro-oesophageal reflux disease (GORD) in infants aged reflux and GORD and their management including prescribing of acid-suppressant medicines (proton pump inhibitors (PPIs) and histamine receptor antagonists (H2RAs)) and counselling, advice or education. Of all infants' visits, 512 (2.7%) included a diagnosis of reflux (n=413, 2.2%) or GORD (n=99, 0.5%). From 2006 to 2016, diagnostic rates decreased for reflux and increased for GORD. Prescribing of acid suppressants occurred in 43.6% visits for reflux and 48.5% visits for GORD, similar to rates of counselling, advice or education (reflux: 38.5%, GORD: 43.4% of visits). Prescribing of PPIs increased (statistically significant only for visits for reflux), while prescribing of H2RAs decreased. Overprescribing of acid suppressants to infants may be occurring. In infants, acid-suppressant medicines are no better than placebo and may have significant negative side effects; however, guidelines are inconsistent. Clear, concise and consistent guidance is needed. GPs and parents need to understand what is normal and limitations of medical therapy. We need a greater understanding of the influences on GP prescribing practices, of parents' knowledge and attitudes and of the pressures on parents of infants with these conditions. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    Full Text Available Mental Retardation (MR is a developmental disability characterized by impairments in adaptive daily life skills and difficulties in social and interpersonal functioning. Since multiple causes may contribute to MR, associated clinical pictures may vary accordingly. Nevertheless, when psychiatric disorders as Treatment Resistant Depression (TRD and/or alcohol abuse co-exist, their proper detection and management is often troublesome, essentially due to a limited vocabulary MR people could use to describe their symptoms, feelings and concerns, and the lack of reliable screening tools. Furthermore, MR people are among the most medicated subjects, with (over prescription of antidepressants and/or typical antipsychotics being the rule rather than exception. Thus, treatment resistance or even worsening of depression, constitute frequent occurrences. This report describes the case of a person with MR who failed to respond to repetitive trials of antidepressant monotherapies, finally recovering using aripiprazole to fluvoxamine augmentation upon consideration of a putative bipolar diathesis for “agitated” TRD. Although further controlled investigations are needed to assess a putative bipolar diathesis in some cases of MR associated to TRD, prudence is advised in the long-term prescription of antidepressant monotherapies in such conditions.

    Gastro-oesophageal reflux disease is a particularly common condition in preterm and low birth weight infants. These infants are also more likely to have excessive regurgitation, as they do not have a fully developed antireflux mechanism. Preterm and low birth weight infants who are unable to suck oral feeds are required to be fed via an intragastric tube for varying lengths of time. Intragastric tube feeding can be delivered by the intermittent bolus or continuous feeding method. Use of continuous or intermittent bolus intragastric feeding may have a positive or negative effect on the incidence or severity of gastro-oesophageal reflux disease. To determine whether continuous or intermittent bolus intragastric tube feeding reduces the number of episodes and the duration of gastro-oesophageal reflux disease (GORD) in preterm and low birth weight infants.We intended to perform subgroup analyses for gestational age; birth weight; age in days from birth at full enteral feeding via intragastric tube (breast vs bottle); frequency of intermittent bolus feed; and type of medication for treatment of GORD (only if medication prescribed and given similarly to both intervention groups). We used the standard search strategy of the Cochrane Neonatal Group as described in The Cochrane Library (www.thecochranelibrary.com) to search for randomised controlled trials (RCTs) in the Cochrane Central Register of Controlled Trials (CENTRAL) (2013, Issue 9), MEDLINE (1966 to September 2013), EMBASE (1980 to September 2013) and the Cumulative Index to Nursing and Allied Health Literature (CINAHL) (1982 to September 2013). We also searched previous reviews, including cross-references, abstracts and conference and symposia proceedings of the Perinatal Society of Australia and New Zealand and the Pediatric Academic Societies (American Pediatric Society/Society for Pediatric Research and European Society for Paediatric Research) from 1990 to 2012.

    Swedish massage is one of the common treatments to provide optimal start and readiness of athletes. The ability of kinesthetic differentiation (KD) is crucial in sport performance. This skill allows to adapt demanded muscle forces to optimize the motor tasks, and it is responsible for the precision. In the literature, there is no evidence how Swedish massage influences the kinesthetic differentiation. The objective of the study was to evaluate the impact of Swedish massage on the kinesthetic differentiation and muscle strength of hand grip. Thirty participants took part in this investigation (17 women and 13 men). The assessment consisted of KD tests conducted on the dominant (DH) and nondominant hand (NDH) after 15 minutes of hand and forearm Swedish massage. The procedure consisted of 13 trials for each extremity. The first three were done for 100% of the participants' capabilities (Fmax), the next five trials were done using 50% of maximum force (50% of Fmax), and in the last five trials, the participants tried to use only 50% of their previous force (1/2 of 50%). Finally, the absolute force production error (FPE) was calculated for 50% (FPE_50%) and 25% (FPE_25%). The two-way repeated measure analysis of variance ANOVA did not reveal any statistically significant changes in maximal strength grip and KD between pre- and postmassage intervention in both DH and NDH hand. Correlations showed strong relationship between pre- and postmassage for maximum force (r = 0.92, p = .01 for DH, and r = 0.94, p = .01 for NDH), and only for the FPE_50% (r = 0.67, p = .01 for DH, and r = 0.71, p = .01 for NDH). The results obtained indicated that the application of the Swedish massage did not affect the kinesthetic differentiation in this particular young adult group.

    Despite the undoubted benefit of proton pump inhibitors (PPIs), they have several shortcomings, such as a slow onset of action and a remarkable inter-individual variability, that limit the complete success of these drugs. Recently, a new PPI, ilaprazole, has been developed and used in GERD patients. The present review provides an update on the following points: current knowledge of GERD mechanisms; limitations of actual therapies; pharmacokinetic profile and metabolism of ilaprazole; initial studies on the therapeutic efficacy of ilaprazole in GERD. Compared with all other approved PPIs, ilaprazole has shown an extended plasma half-life, a metabolism not significantly influenced by CYP2C19 genetic polymorphism and similar safety. This characteristics account for a low inter-individual variability, particularly in Asian populations, a higher suppression of gastric acid secretion, a more rapid acid control and consequent quicker symptom relief and a better effect on nocturnal acidity. However, clinical investigations assessing the efficacy of ilaprazole in the management of GERD are lacking and therefore the potential improvements achievable with ilaprazole in the current standard of care for acid-suppressing treatment must be confirmed in large and randomly controlled clinical trials enrolling patients with both erosive and non-erosive reflux disease.

    Gastro-oesophageal reflux disease (GORD) is on the rise with more than 20% of the western population reporting symptoms and is the most common gastrointestinal disorder in the United States. This increase in GORD is not exactly clear but has been attributed to the increasing prevalence of obesity, changing diet, and perhaps the decreasing prevalence of H. pylori infection. Complications of GORD could be either benign or malignant. Benign complications include erosive oesophagitis, bleeding and peptic strictures. Premalignant and malignant lesions include Barrett's metaplasia, and oesophageal cancer. Management of both the benign and malignant complications can be challenging. With the use of proton-pump inhibitors, peptic strictures (i.e., strictures related to reflux) have significantly declined. Several aspects of Barrett's management remain controversial including the stage in the disease process which needs to be intervened, type of the intervention and surveillance of these lesions to prevent development of high grade dysplasia and oesophageal adenocarcinoma.

    To study the relationship between esophageal motor functional disorder [decreased lower esophageal sphincter pressure (LESP)and ineffective motility (IEM)] and gastroesophageal reflux disease (GERD). Totally 89 patients with GERD were enrolled in this study. All of them underwent 24-hour pH monitoring with dual-channel probe and stationary esophageal manometry. In addition, 77 of these patients underwent upper endoscopy. IEM and LES, 10 mmHg were common disturbances in patients with GERD (54% and 48%, respectively). The number of the acid reflux events of distal esophagus and prevalence of moderate or severe erosive esophagitis (EE) were significantly higher in patients with low LESP and IEM than patients without low LESP ( Pesophagus was significantly correlated with the severity of esophagitis, distal esophagus amplitude, and LESP, while no such correlation was found between IEM and degree of esophageal acid exposure or esophagitis. The pathophysiology of GERD is probably multifactorial. Lower LESP or IEM is not a independent pathophysiological factor for GERD. However,one single factor is insufficient to explain all the pathogenic mechanism of GERD.

    The development of lipid aspiration pneumonia after chronic nasopharyngeal installation of mineral oil was first described in 1925 by Laughlin. Since that time this entity has been well recognized and numerous substances have been identified or implicated as the aspirated material. The classic radiographic appearance of severe chronic lipid aspiration pneumonia has been described as consisting of intense perihilar infiltrates. However, the radiographic findings are more often non-specific and usually consist of varying degrees of diffuse interstitial infiltrates that tend to be more prominent in the perihilar regions and the right lung. We are reporting a case of biopsy-proven lipid aspiration pneumonia in an infant with known gastro-esophageal reflux (GER) who had medium-chain triglyceride oil administered via nasogastric tube. Serial roentgenograms demonstrated a changing pulmonary pattern from diffuse bilateral interstitial infiltrates initially to a diffuse alveolar pattern at the time of the lung biopsy. Modern medicine has developed new methods for providing nourishment to sick newborns and infants to improve their nutritional status and help them to grow. One such method involves the administration of medium-chain triglycerides (MCT oil) into the GI tract via a nasogastric or nasoenteral tube. The purpose of this report is to describe a significant complication of this method of providing nutrition to an infant with gastroesophageal reflux (GER) and the diagnostic dilemma it presented.

  14. How useful is gastroesophageal reflux scintigraphy in suspected childhood aspiration

    1988-05-01

    It has been suggested that gastroesophageal reflux scintigraphy might be useful in assisting one in determining therapy for patients suspected of aspirating or becoming apneic secondary to gastroesophageal reflux. This, however, has not been our experience and in reviewing 23 patients with recurrent pneumonia and/or apnea who had gastroesophageal reflux scintigraphy, we were able to detect aspiration in only one. This was especially significant since 13 (59%) of these patients had demonstrable reflux, and of these, eight were treated successfully for suspected aspiration even though none was demonstrated isotopically. To be sure, the demonstration of pulmonary aspiration with gastroesophageal reflux scintigraphy had little influence on patient selection and response to therapy. For this reason we feel there is little justification in depending on the GRS for the specific purpose of trying to document pulmonary aspiration in infants and children who are refluxing. One of the more serious complications of gastroesophageal (GE) reflux is aspiration leading to recurrent pulmonary infections and/or apnea. However, it always has been difficult to demonstrate actual aspiration into the lungs, and to be sure, barium studies of the upper GI tract seldom reveal this complication. Recently, however, considerable interest has been generated in gastroesophageal scintigraphy (GRS) as a possible means of documenting such aspiration. Rationale for this stems from the fact that suspected patients can be studied over a longer period of time and in addition, delayed and overnight images can be obtained. However, our experience does not support GRS as being an adequate method for demonstrating aspiration.

    Full Text Available Abstract Background Collaboration between providers of conventional care and complementary therapies (CTs has gained in popularity but there is a lack of conceptualised models for delivering such care, i.e. integrative medicine (IM. The aim of this paper is to describe some key findings relevant to the development and implementation of a proposed model for IM adapted to Swedish primary care. Methods Investigative procedures involved research group and key informant meetings with multiple stakeholders including general practitioners, CT providers, medical specialists, primary care administrators and county council representatives. Data collection included meeting notes which were fed back within the research group and used as ongoing working documents. Data analysis was made by immersion/crystallisation and research group consensus. Results were categorised within a public health systems framework of structures, processes and outcomes. Results The outcome was an IM model that aimed for a patient-centered, interdisciplinary, non-hierarchical mix of conventional and complementary medical solutions to individual case management of patients with pain in the lower back and/or neck. The IM model case management adhered to standard clinical practice including active partnership between a gate-keeping general practitioner, collaborating with a team of CT providers in a consensus case conference model of care. CTs with an emerging evidence base included Swedish massage therapy, manual therapy/naprapathy, shiatsu, acupuncture and qigong. Conclusion Despite identified barriers such as no formal recognition of CT professions in Sweden, it was possible to develop a model for IM adapted to Swedish primary care. The IM model calls for testing and refinement in a pragmatic randomised controlled trial to explore its clinical effectiveness.

Thirteen of the twenty two children present a pathologic reflux (ERGE); in 16 we found SEGD that show reflux; three of them had an abnormal EM, the other 13 were normal. Seven patients showed alteration of the intraesophageal pH measurement. In conclusion the intraesophageal pH measurement in short period of time (4 hours) is a good method in the diagnosis of patients with ERGE.

    A case of malacoplakia involving the lower urinary tract of a young black boy, with associated bilateral vesicoureteral reflux, hydronephrosis and selective immunoglobulin A deficiency is reported. Reflux was caused by the malacoplakia. Reflux and hydronephrosis persisted despite elimination of bacterial infection and malacoplakia by drug therapy. These abnormalities were corrected by a conventional antireflux operation. Malacoplakia appears to be related to immunologic incompetence and diminished levels of intracellular cyclic 3',5' guanine monophosphate. Cholinergic agonists reverse or prevent the pathological changes of malacoplakia.

    Some patients with gastroesophageal reflux disease experience persistent reflux symptoms despite proton pump inhibitor therapy. These symptoms reduce their health-related quality of life. Our aims were to evaluate the relationship between proton pump inhibitor efficacy and health-related quality of life and to evaluate predictive factors affecting treatment response in Japanese patients. Using the gastroesophageal reflux disease questionnaire, 145 gastroesophageal reflux disease patients undergoing proton pump inhibitor therapy were evaluated and classified as responders or partial-responders. Their health-related quality of life was then evaluated using the 8-item Short Form Health Survey, the Pittsburgh Sleep Quality Index, and the Hospital Anxiety and Depression Scale questionnaires. Sixty-nine patients (47.6%) were partial responders. These patients had significantly lower scores than responders in 5/8 subscales and in the mental health component summary of the 8-item Short Form Health Survey. Partial responders had significantly higher Pittsburgh Sleep Quality Index and Hospital Anxiety and Depression Scale scores, including anxiety and depression scores, than those of responders. Non-erosive reflux disease and double proton pump inhibitor doses were predictive factors of partial responders. Persistent reflux symptoms, despite proton pump inhibitor therapy, caused mental health disorders, sleep disorders, and psychological distress in Japanese gastroesophageal reflux disease patients.

  2. Estimating Swedish biomass energy supply

    Biomass is suggested to supply an increasing amount of energy in Sweden. There have been several studies estimating the potential supply of biomass energy, including that of the Swedish Energy Commission in 1995. The Energy Commission based its estimates of biomass supply on five other analyses which presented a wide variation in estimated future supply, in large part due to differing assumptions regarding important factors. In this paper, these studies are assessed, and the estimated potential biomass energy supplies are discusses regarding prices, technical progress and energy policy. The supply of logging residues depends on the demand for wood products and is limited by ecological, technological, and economic restrictions. The supply of stemwood from early thinning for energy and of straw from cereal and oil seed production is mainly dependent upon economic considerations. One major factor for the supply of willow and reed canary grass is the size of arable land projected to be not needed for food and fodder production. Future supply of biomass energy depends on energy prices and technical progress, both of which are driven by energy policy priorities. Biomass energy has to compete with other energy sources as well as with alternative uses of biomass such as forest products and food production. Technical progress may decrease the costs of biomass energy and thus increase the competitiveness. Economic instruments, including carbon taxes and subsidies, and allocation of research and development resources, are driven by energy policy goals and can change the competitiveness of biomass energy

    We compared newly developed radionuclide cystography with conventional contrast voiding cystography (VCG) with regard to their diagnostic usefulness of intrarenal reflux (IRR) in children. Based on the imaging findings, we assessed the role of IRR in the pathogenesis of reflux nephropathy (RN). Among the ureters which revealed IRR diagnosed by radionuclide cystography, 38.9% (7 out of 18 ureters) of the cases examined by VCG had IRR. In the case of VCG, the sensitivity and specificity of IRR detection were 33.3% and 100%, respectively. There was a statistical correlation between the presence/absence of IRR and vesicoureteral reflux (VUR). RN was significantly correlated with advanced grade of VUR associated with IRR. Among 9 kidneys of the subjects who had suffered from urinary tract infection (UTI) only once, IRR was detected in 33.3% (3/9) and RN in 66.7% (2/3). From these findings, conventional contrast VCG is considered not effective for the diagnosis of IRR. Moreover, it is suggested that VUR complicated with IRR is deeply associated with the development of RN. In addition, it is suggested that UTI might be related to the onset of IRR. (author)

    Purpose: To study the long-term development of urographic renal morphology in adults with vesicoureteral reflux, to investigate the relationship between renal damage and reflux grade, and to analyse the association between the long-term urographic outcome and the occurrence of acute pyelonephritis and reflux during follow-up. The purpose was also to try to distinguish between acquired and developmental renal damage, based on analyses of renal histological specimens and urographic features, and to analyse associated congenital urogenital abnormalities and family history of reflux, reflux nephropathy, urological malformation or death from end-stage renal disease. Material and Methods: Renal damage was identified in 100 (83 women) of 115 adults, selected because of documented reflux. Eighty-seven patients had two urographies done (median interval 14.3 years). The extent and progression of renal damage were assessed and features of developmental renal damage were determined. Histological renal specimens were available in 23 patients with renal damage. Results and Conclusions: The extent of renal damage correlated positively with the severity of reflux. No renal damage developed during the follow-up in 45 previously undamaged kidneys and progression of renal damage was rare (4 of 120 previously damaged kidneys), despite persisting reflux in half of the cases and episodes of acute pyelonephritis during follow-up. Thus, repeated renal imaging is rarely justified in adults with reflux nephropathy. Histological examination showed 'chronic pyelonephritis' in all 23 cases and co-existing renal dysplasia in 1 case. The detailed urographic analysis did not reveal support for developmental renal damage. High frequencies of associated congenital urogenital abnormalities and of a positive family history were found. Thus, congenital and/or hereditary factors cannot be discarded as background factors for the development of renal damage

    Alginate rafts (polysaccharide polymers that precipitate into a low-density viscous gel when they contact gastric acid) have been reported to form at the acid pocket, an unbuffered pool of acid that floats on top of ingested food and causes postprandial acid reflux. We studied the location of an alginate formulation in relation to the acid pocket and the corresponding effects on reflux parameters and acid pocket positioning in patients with gastroesophageal reflux disease (GERD). We randomly assigned patients with symptomatic GERD and large hiatal hernias to groups who were given either (111)In-labeled alginate-antacid (n = 8, Gaviscon Double Action Liquid) or antacid (n = 8, Antagel) after a standard meal. The relative positions of labeled alginate and acid pocket were analyzed for 2 hours by using scintigraphy; reflux episodes were detected by using high-resolution manometry and pH-impedance monitoring. The alginate-antacid label localized to the acid pocket. The number of acid reflux episodes was significantly reduced in patients receiving alginate-antacid (3.5; range, 0-6.5; P = .03) compared with those receiving antacid (15; range, 5-20), whereas time to acid reflux was significantly increased in patients receiving alginate-antacid (63 minutes; range, 23-92) vs those receiving antacid (14 minutes; range, 9-23; P = .01). The acid pocket was located below the diaphragm in 71% of patients given alginate-antacid vs 21% of those given antacid (P = .08). There was an inverse correlation between a subdiaphragm position of the acid pocket and acid reflux (r = -0.76, P acid pocket and displaces it below the diaphragm to reduce postprandial acid reflux. These findings indicate the importance of the acid pocket in GERD pathogenesis and establish alginate-antacid as an appropriate therapy for postprandial acid reflux. Copyright © 2013 AGA Institute.

    Full Text Available Abstract Background In a cross-sectional community based study, as part of a randomised controlled trial of eradication of Helicobacter pylori infection, the association between blood pressure and symptoms of gastro-oesophageal reflux was examined. Methods Linear regression was used to examine the association between systolic and diastolic blood pressure and the frequency of heartburn and acid regurgitation in 4,902 of 10,537 participants aged 20–59 years. Results In multivariable analyses, adjusted mean systolic blood pressure was 4.2 (95% confidence interval 1.5 to 7.0 mm Hg lower in participants with daily acid regurgitation compared to those with less frequent symptoms. Similarly, for diastolic blood pressure, a reduction of 2.1 (0.0 to 4.3 mm Hg wasobserved. Conclusion People who experience daily symptoms of gastro-oesophageal reflux have lower blood pressure than people with less frequent or no symptoms. It is possible that factors influencing nitric oxide concentrations both at the lower oesophageal sphincter and within the vasculature may be involved. This hypothesis requires confirmation.

    The objective of this study was to evaluate the validity of the Heartburn Reflux Dyspepsia Questionnaire (HRDQ), a newly developed measure of gastro-oesophageal reflux disease (GORD) symptoms. Specifically, the HRDQ was developed for patients, who still experience symptoms with proton pump inhibitor (PPI) treatment. The psychometric properties of HRDQ were evaluated based on data from two clinical trials of patients with GORD with a partial response to PPIs, one from the UK and one from Denmark and Germany. The HRDQ had good internal consistency (Cronbach's alpha range .83-.88) and test-retest reliability (intraclass correlation coefficient range .71-.90). Convergent and discriminant validity were supported by high correlations with ReQuest™ and ability to differentiate between groups based on ReQuest™ cut-off values. Responsiveness of HRDQ was demonstrated by moderate to high correlations with ReQuest™ change scores and time with symptoms. An HRDQ cut-off value of 0.70 for definition of 'bad day' was also evaluated. Based on existing evidence, the HRDQ is a valid and reliable measure of GORD symptoms that can be used as a study outcome in clinical trials.

    The patients treated for oesophageal atresia present a correlation between the clinical sintomatology after recanalization characterized by disfagia, dispnea, recurrent cough, chronic pneumopaties and oesophageal anomalies. Where morphological alterations accounting for the presence of gastro-oesophageal reflux (GOR) were not evident, possible functional alterations of the motility were considered. The incidence of GOR was considerably high and, expression of a congenital alteration of the lower oesophageal sphincter and of oesophageal peristalsis, becomes even more severe due to further stretching of the gastro-esophageal junction. The authors underline that the early demonstration of histological changes, even before recanalization, and the motility disorders of the oesophagus have to be well studied, while the LES is normalized, in order to prevent and treat the possible appearance of the well-known complications of GOR.

    Chronic gastroesophageal reflux disease was diagnosed in a 22-year-old female Tennessee Walking Horse that had signs of bruxism and ptyalism. Esophageal ulceration was detected via endoscopy. Compared with the damage to the proximal portions of the esophagus, the severity of the ulceration increased toward the gastroesophageal junction. Esophageal ulceration attributable to chronic gastric acid reflux is usually secondary to pyloric outflow obstruction in horses. In the horse of this report, there was no evidence of either a chronic pyloric or duodenal obstruction that could have resulted in esophageal ulceration. Esophageal ulceration in this horse was attributed to gastroesophageal reflux disease, a common condition in humans in which the underlying abnormality is functional incompetence of the gastroesophageal junction. Treatment is directed at decreasing gastric acidity and protecting the ulcerated mucosa. In the horse of this report, treatment was unsuccessful and the horse was euthanatized; a physical cause of gastroesophageal reflux disease was not identified during an extensive postmortem examination.

    A wide variety of symptoms and diseases of the upper aerodigestive tract are associated to gastro-oesophageal reflux disease (GORD). These disorders comprise a large variety of conditions such as asthma, chronic otitis media and sinusitis, chronic cough, and laryngeal disorders including paroxysmal laryngospasm. Laryngo-pharyngeal reflux disease is an extraoesophageal variant of GORD that can affect the larynx and pharynx. Despite numerous research efforts, the diagnosis of laryngopharyngeal reflux often remains elusive, unproven and controversial, and its treatment is then still empiric. Aim of this paper is to review the current literature on upper aerodigestive tract disorders in relation to pathologic gastro-oesophageal reflux, focusing in particular on the pathophysiology base and results of the surgical treatment of GORD.

    Approximately 20-30% of patients with gastro-esophageal reflux symptoms report inadequate symptom relief while on proton-pump inhibitor therapy. The mechanisms involved are failure of the antireflux barrier (transient lower esophageal sphincter relaxations), high proximal extent of the refluxate, esophageal hypersensitivity and impaired mucosal integrity. Persisting acid or nonacid reflux can be demonstrated in 40-50% of cases, suggesting that there is room for antireflux therapy in these patients. New antireflux compounds have been shown to decrease the occurrence of transient lower esophageal sphincter relaxations. The most promising classes of compounds are GABA type B agonists and metabotropic glutamate receptor 5 antagonists, which can reduce both reflux episodes and symptoms, but the development of these compounds has been abandoned for either safety issues or lack of efficacy. Esophageal hypersensitivity and impaired mucosal integrity may prove to be relevant therapeutic targets in the future.

    After the reactor accident at Three Mile Island, the Swedish nuclear power plants were equipped with filtered venting of the containment. Several types of accidents can be identified where the filtered venting has no effect on the radioactive release. The probability for such accidents is hopefully very small. It is not possible however to estimate the probability accurately. Experiences gained in the last years, which have been documented in official reports from the Nuclear Power Inspectorate indicate that the probability for core melt accidents in Swedish reactors can be significantly larger than estimated earlier. A probability up to one in a thousand operating years can not be excluded. There are so far no indications that aging of the plants has contributed to an increased accident risk. Maintaining the safety level with aging nuclear power plants can however be expected to be increasingly difficult. It is concluded that the 12 Swedish plants remain a major threat for severe radioactive pollution of the Swedish environment despite measures taken since 1980 to improve their safety. Closing of the nuclear power plants is the only possibility to eliminate this threat. It is recommended that until this is done, quantitative safety goals, same for all Swedish plants, shall be defined and strictly enforced. It is also recommended that utilities distributing misleading information about nuclear power risks shall have their operating license withdrawn. 37 refs.

    Gastroesophageal reflux disease is common in adult patients with interstitial lung disease. However, no data currently exist regarding the prevalence and characteristics of the disease in pediatric patients with interstitial lung disease. The aim of the present study was to prospectively assess the incidence of gastroesophageal reflux disease and characterize its features in children with interstitial lung disease. Gastroesophageal reflux disease was established based on 24 h pH-impedance monitoring (MII-pH). Gastroesophageal reflux episodes (GERs) were classified according to widely recognized criteria as acid, weakly acid, weakly alkaline, or proximal. Eighteen consecutive patients (15 boys, aged 0.2-11.6 years) were enrolled in the study. Gastroesophageal reflux disease was diagnosed in a half (9/18) of children. A thousand GERs were detected by MII-pH (median 53.5; IQR 39.0-75.5). Of these, 585 (58.5 %) episodes were acidic, 407 (40.7 %) were weakly acidic, and eight (0.8 %) were weakly alkaline. There were 637 (63.7 %) proximal GERs. The patients in whom gastroesophageal reflux disease was diagnosed had a significantly higher number of proximal and total GERs. We conclude that the prevalence of gastroesophageal reflux disease in children with interstitial lung disease is high; thus, the disease should be considered regardless of presenting clinical symptoms. A high frequency of non-acid and proximal GERs makes the MII-pH method a preferable choice for the detection of reflux episodes in this patient population.

    2008-01-01

    Imaging of children with a clinical diagnosis of pyelonephritis is performed to characterize the extent of the infection, to identify associated renal injury and to uncover risk factors for future infections and renal damage. Although there is general agreement regarding the need for parenchymal imaging and the need to exclude processes that are either functionally or anatomically obstructive, there is controversy regarding the need for routine cystography, especially when parenchymal involvement has not been documented. A protocol that limits the use of cystography for evaluation of urinary tract infections must assume that the diagnosis of reflux is at least of variable clinical significance. It is now clear that vesicoureteral reflux and reflux nephropathy represent a diverse population that includes both congenital and acquired processes. MR imaging will improve our understanding of vesicoureteral reflux, pyelonephritis and renal scarring and might help us to identify and manage those patients most at risk for recurrent infections and renal injury. To recognize the potential contributions of this newer imaging technique it is helpful to look at our understanding of the pathophysiology of pyelonephritis, reflux and reflux nephropathy. (orig.)

    Gastro-oesophageal reflux is common and benign in children, especially during infancy. Distinguishing between gastrooesophageal reflux, gastro-oesophageal reflux disease and other illnesses presenting as chronic vomiting can be difficult. The general practitioner has a key role to play in identifying if a child requires referral for further investigation. This article outlines the main differential diagnoses to be considered in children presenting with chronic vomiting and/ or regurgitation. We also discuss key management decisions regarding gastro-oesophageal reflux disease in children and when to refer to a specialist for further investigation. Chronic vomiting and regurgitation frequently occurs in infancy and is most commonly due to simple, benign gastrooesophageal reflux, which is usually self limiting without requirement for further investigation. In contrast, gastrooesophageal reflux disease requires considered management and may be a presenting symptom of food allergy requiring more intensive therapy than simple acid suppression. Regular review by the general practitioner to ascertain warning signs will ensure that other serious illnesses are not overlooked and that appropriate investigation and specialist referral are made.

    The National Ambulatory Medical Care Survey (NAMCS) database was utilized to understand evolving national trends in diagnosis and management of reflux. The NAMCS database was queried for visits related to gastroesophageal reflux diagnosis and management. Analysis performed for time periods 1998-2001, 2002-2005, and 2006-2009 was weighted to provide national estimates of care. Results were compared to previously reported time periods from 1990 to 2001 to evaluate patterns in overall visits, age and ethnicity of patients, provider type, and prescriptions provided. The number of ambulatory visits for reflux increased from 8 684 000 in 1998-2001 to 15 750 000 in 2006-2009. Visits increased across each time period for internal medicine, family, and gastroenterology physicians. Among otolaryngologists, absolute visits increased from 1998-2001 to 2002-2005 but decreased in 2006-2009; difference between these time periods did not reach statistical significance. From 1998-2001 to 2006-2009, reflux medication use increased 233%, with continuing trends toward increased proton pump inhibitor use. Reflux visits have increased across all demographic subgroups studied. Knowledge of these trends may inform further paradigm shifts in diagnosis and management of reflux.

    This paper investigates the redistributive effects of the Swedish health care financing system in 1980 and 1990 for four different financial sources: county council taxes, payroll taxes, direct payments and state grants. The redistributive effects are decomposed into vertical, horizontal and 'reranking' segments for each of the four financial sources. The data used are based on probability samples of the Swedish population, from the Level of Living Survey (LNU) from 1981 and 1991. The paper concludes that the Swedish health care financing system is weakly progressive, although direct payments are regressive. There is some horizontal inequity and 'reranking', which mainly comes from the county council taxes, since those tax rates vary for each county council. The implication is that, to some extent, people with equal incomes are treated unequally.

    Multichannel impedance pH monitoring has shown that weakly acidic refluxes are able to generate heartburn. However, data on the role of different pH values, ranging between 4 and 7, in the generation of them are lacking. The aim of this study was to evaluate whether different pH values of weakly acidic refluxes play a differential role in provoking reflux symptoms in endoscopy-negative patients with physiological esophageal acid exposure time and positive symptom index and symptom association probability for weakly acidic refluxes. One hundred and forty-three consecutive patients with gastroesophageal reflux disease, nonresponders to proton pump inhibitors (PPIs), were allowed a washout from PPIs before undergoing: upper endoscopy, esophageal manometry, and multichannel impedance pH monitoring. In patients with both symptom index and symptom association probability positive for weakly acidic reflux, each weakly acidic reflux was evaluated considering exact pH value, extension, physical characteristics, and correlation with heartburn. Forty-five patients with normal acid exposure time and positive symptom association probability for weakly acidic reflux were identified. The number of refluxes not heartburn related was higher than those heartburn related. In all distal and proximal liquid refluxes, as well as in distal mixed refluxes, the mean pH value of reflux events associated with heartburn was significantly lower than that not associated. This condition was not confirmed for proximal mixed refluxes. Overall, a low pH of weakly acidic reflux represents a determinant factor in provoking heartburn. This observation contributes to better understand the pathophysiology of symptoms generated by weakly acidic refluxes, paving the way toward the search for different therapeutic approaches to this peculiar condition of esophageal hypersensitivity. © 2014 International Society for Diseases of the Esophagus.

    Abstract To determine the relationship between baseline impedance levels and gastroesophageal reflux, we retrospectively enrolled 110 patients (54 men and 56 female; mean age, 51 ± 14 years) with suspected gastroesophageal reflux disease (GERD) who underwent 24-h multichannel intraluminal impedance and pH monitoring. Patients were stratified according to symptom (typical or atypical) and reflux types (acid reflux, nonacid reflux [NAR], or no abnormal reflux). Mean nocturnal baseline impedance (MNBI) were measured 3 cm (distal esophagus) and 17 cm (proximal esophagus) above the lower esophageal sphincter. Median distal esophageal MNBI was lower in the acid reflux group (1244 Ω; 647–1969 Ω) than in the NAR (2586 Ω; 1368–3666 Ω) or no abnormal reflux groups (3082 Ω; 2495–4472 Ω; all P < .05). Distal MNBI were negatively correlated with DeMeester score and acid exposure time. Atypical symptoms were more frequently associated with NAR than typical symptoms (P < .01). Among patients with positive symptom-association probability (SAP) for NAR, median proximal MNBI tended to be lower in patients with typical symptoms (median, 3013 Ω; IQR, 2535–3410 Ω) than in those with atypical symptoms (median, 3386 Ω; IQR, 3044–3730 Ω, P = .05). Thus, atypical GERD symptoms were more likely to be associated with NAR. The mucosal integrity of the proximal esophagus might be relatively impaired in GERD patients with typical symptoms for NAR.

    The aim of this study is to evaluate the usefulness of gastroesophageal reflux (GER) scintigraphy using the knee-chest (KC) position for the diagnosis of gastroesophageal reflux disease (GERD). The study subjects were 37 patients with GERD and 8 healthy volunteers (control group). Endoscopically observed esophageal mucosal breaks were evaluated with the Los Angeles classification. For GER scintigraphy, the subjects ingested liquid yogurt labeled with 99m Tc-diethylene triamine pentaacetic acid ( 99m Tc-DTPA) and water. Imaging was performed in the supine and KC position, and GER was graded as 1-4 according to the extent of GER assessed by scintigraphy. GER scintigraphy revealed no reflux in the control group (specificity: 100%). In the supine position, gastroesophageal reflux was observed in 49% of the patients with GERD, compared to 76% in the KC position. 21 of 23 (91%) patients with erosive esophagitis were shown to have GER with scintigraphy. GER scintigraphy revealed severe reflux (grade 3 or 4) (83%, 10/12) in the patients who had severe mucosal breaks (the Los Angels classification grade C or D). GER scintigraphy detected grade 1 or 2 reflux in 7 of the 14 patients who were endoscopically negative. There was a correlation between the endoscopically determined severity of mucosa and the reflux grade which was determined with GER scintigraphy. GER scintigraphy can detect gastroesophageal reflux with a high sensitivity in the KC position and might be a useful method in the screening and assessment of the severity of this disease. This method would be useful for the diagnosis of GERD in endoscopically negative patients. (author)

    Background: Risk management has always been a complex topic, especially when it comes to hedge funds. Since hedge funds are able to utilize many kinds of financial instruments it is difficult to find a risk management strategy that goes well with them. Not much research regarding the Swedish hedge fund industry and its risk management has been done; hence we find it an interesting topic to focus this thesis on. Purpose: The purpose of this thesis is to increase the knowledge of how Swedish he...

    Doses to about 1000 Swedish patients in 13 hospitals and several photofluorographic and dental installations were measured. The measurements comprised radiation quality, exposure-area product and doses to a few parts of the body where dosimeters could be placed. Calculations yielded energy imparted as well as doses to the thyroid, mammae, lungs, bone marrow, ovaries and testes. The possibility of reducing patientdoses is discussed. The radiation risk to the Swedish population isestimated,based on mean annual collective dose per individual for different body organs.(K.K.)

    Literature has addressed the increased prevalence of gastroesophageal reflux disease (GERD) in obstructive sleep apnea (OSA). Significant improvement of GERD has been found after OSA treatment. However, precise mechanisms underlying this correlation remain unclear. We examined the association between nocturnal gastroesophageal reflux (GER) and sleep events in patients with coexisting OSA and GERD. A case-crossover study among 12 patients with coexisting moderate-severe OSA and GERD was conducted. Participants underwent simultaneous polysomnography and esophageal impedance and pH monitoring. GER subtypes (ie, acid reflux, non-acid reflux) were defined as outcomes. Respective control time points were selected in all eligible control periods. Each sleep event was assessed individually. Estimated odds ratios (ORs) and 95% confidence intervals (CIs) were analyzed. A p-value of reflux and 28 non-acid reflux. Arousals and awakenings were significantly associated with subsequent GER events. The OR for GER following an arousal was 2.31 (95% CI 1.39-3.68; p  0.05). Both awakening and arousal appear to precipitate any subtype of GER events in patients with coexisting GERD and moderate to severe OSA. However, GER events were significantly less likely to occur after other respiratory events and did not appear to cause sleep-related events. Copyright © 2016 Elsevier B.V. All rights reserved.

    Highlights: • Behavior of a reflux condensation heat transfer was investigated for SBLOCA tests. • Behavior of the reflux condensate in HL, SG inlet plenum, and U-tubes were evaluated. • Concept of a steam moisturizing phenomenon was introduced and discussed. • Test data and MARS calculations were compared and discussed on the reflux condensate. - Abstract: The behavior of the reflux condensation heat transfer in a hot side steam generator (SG) U-tubes during a cold leg (CL) pipe and a direct vessel injection (DVI) line break in small break loss-of-coolant accident (SBLOCA) tests of the ATLAS facility was investigated including MARS code calculations. Among the SBLOCA tests, a 6″-CL pipe and 50%-DVI line break SBLOCA test were selected to investigate the behavior of the reflux condensation. A reflux condensation heat transfer seemed to occur from the time the SG U-tubes were half-empty to near the loop seal clearing (LSC). It was found that a transition regime existed between the reflux condensation heat transfer and reverse heat transfer. The remaining reflux condensate in SG U-tubes owing to the counter-current flow limit (CCFL) phenomenon and a separating effect of liquid carry-over and/or entrainment with steam moisturizing seemed to affect the thermal-hydraulic behavior of the transition regime. It was also found that the steam flowrate of the loop pipings and SG U-tubes seemed to have a strong effect on the duration time of the transition regime, e.g., a larger steam flowrate results in a longer duration. From a comparison of the reflux condensation behavior between the ATLAS tests and MARS code calculations, overall qualitative agreements were found between the two cases. The largest discrepancies were found in the SG inlet plenum water level between the two cases, and the authors suggest that the combination effects of the remaining reflux condensate in SG U-tubes and a separating effect of liquid carry-over and/or entrainment with steam

    Gastroesophageal reflux disease (GERD) can be classified into erosive reflux disease (ERD) and nonerosive gastroesophageal reflux disease (NERD). We aimed to compare the recurrence rates of ERD and NERD and determine the risk factors related to the recurrence. This prospective study comprised 337 consecutive adults who completed questionnaires on their GERD symptoms, height, weight, sleeping position, dinner time, and bedtime. During upper gastrointestinal endoscopy, the presence of a hiatal hernia and mucosal breaks in the low esophagus, esophageal length (the distance between the Z-line and the incisors), and the esophageal length-to-height ratio were recorded. Recurrence was diagnosed when the patient required additional proton pump inhibitor medication after initial recovery with 4-8 weeks of treatment. Recurrence was experienced by 47 (26.0%) of 181 GERD patients. The recurrence rate did not differ between the 48 ERD (27.1%) and 133 NERD (25.6%) patients (P = 0.849). Of the various factors studied, recurrence was found to be correlated with a dinner-to-bedtime interval of less than 3 h (P = 0.002), globus sensation (P = 0.031), and old age (P = 0.047). Logistic regression analysis revealed that a short interval between dinner and bedtime was the only factor significantly related to the recurrence (P = 0.002). Both ERD and NERD patients who sleep within 3 h after eating have a higher risk of GERD recurrence. Our findings highlight the impact of a short dinner-to-bedtime interval on the recurrence of GERD (ClinicalTrials.gov ID: KCT0000134). © 2013 Journal of Gastroenterology and Hepatology Foundation and Wiley Publishing Asia Pty Ltd.

    Manipulation of the blood's oxygen carrying capacity (CaO(2)) through reinfusion of red blood cells, injections of recombinant erythropoietin or by other means results in an increased maximal oxygen uptake and concomitantly enhanced endurance performance. Therefore, there is a need to establish a system--"A Blood Pass"--through which such illegal and unethical methods can be detected. Venous blood samples were taken under standardized conditions from 47 male and female Swedish national and international elite endurance athletes four times during the athletic year of the individual sport (beginning and end of the preparation period and at the beginning and during peak performance in the competition period). In these samples, different hematological values were determined. ON(hes) and OFF(hre) values were calculated according to the formula of Gore et al. A questionnaire regarding training at altitude, alcohol use and other important factors for hematological status was answered by the athletes. There were some individual variations comparing hematological values obtained at different times of the athletic year or at the same time in the athletic year but in different years. However, the median values of all individual hematological, ON(hes) and OFF(hre), values taken at the beginning and the end of the preparation or at the beginning and the end of the competition period, respectively, as well as median values for the preparation and competition periods in the respective sport, were all within the 95% confidence limit (CI) of each comparison. It must be mentioned that there was no gender difference in this respect. This study shows that even if there are some individual variations in different hematological values between different sampling times in the athletic year, median values of important hematological factors are stable over time. It must be emphasized that for each blood sample, the 95% CI in each athlete will be increasingly narrower. The conclusion is that

    Recent tracer investigations in Swedish steel plants have mainly dealt with problems concerning uon-metallic inclusions, slag weight determination and - labelling of special steel qualities for identification. Suspected inclusion sources, such as furnace slag, ladle-bottom mortar and some brick materials as stopper, nozzle.and channel bricks have been labelled radioactively in different ways. The labelling technique has been studied for the different systems and a new method was developed for brick materials. This includes vacuum impregnation with an aqueous solution of the inactive tracer, reheating to 1300 Degree-Sign C and neutron-irradiation in a reactor. A sufficiently homogeneous labelling of the material was obtained in this way. The tracer used was terbium, which was added as the nitrate and then decomposed to oxide during the heating process. The oxide is strongly bound to the ceramic material. The number of radioactive inclusions was determined by.autoradiography, and related to the total number pf inclusions, obtained by visual slag-counting, to give the percentage of inclusions originating from the labelled object. Some investigations have been made using simultaneous labelling of two or more sources. It seems to be difficult, however, to measure separately more than two tracers: one short-lived (e.g. 140La) and one long-lived (e.g. {sup 160}Tb). The slag weight determinations were made using the isotope dilution technique with {sup 131}Ba and {sup 140}La as tracers. A difference in slag weight is sometimes obtained. An attempt is made to explain these deviations. The material transport through a blast furnace has been followed by using a piece of graphite, labelled with {sup 140}La{sub 2}O{sub 3}, and measuring the radiation intensity outside the furnace walls and in the tuyere. Studies have been made to determine suitable radiotracers for labelling of steel for subsequent identification. Up to three different isotopes can be used simultaneously

    We reviewed the characteristics of 25 pediatric patients (41 ureters) with primary vesico-ureteral reflux (VUR) who underwent anti-reflux surgery. The patients comprised 14 males and 11 females. The median age at diagnosis and at operation was 5 years 3 months and 6 years 5 months, respectively. VUR grade comprised grade I, 4 cases, grade II, 3 cases, grade III, 11 cases, grade IV, 11 cases and grade V, 12 cases. We utilized the Cohen method as the anti-reflux surgery technique. VUR recurrence was detected in 1 case (2.9%) during follow-up. Moreover, there were no cases with progressive renal dysfunction or breakthrough infection. The rate of kidney with renal scar on scintigraphy before the operation was 48.9%, and the rate of kidney with renal dysfunction before the operation was 60.0%. As a result of Fisher's exact probability test, the risk factors of breakthrough infection (BTI) were high grade VUR and renal scar on scintigraphy. Based on our clinical results, our future strategy for the management of pediatric patients with primary VUR is proposed as follows. In all patients younger than 1 year old, antibacterial prophylaxis should be applied. For patients younger than 6 years old, the initial treatment should be antibacterial prophylaxis, but for patients with VUR of grade III or more, in cases of breakthrough infection or in cases with progressive renal dysfunction, surgical treatment should be considered. For patients older than 6 years with VUR of grade III or more, surgical treatment is strongly recommended. (author)

    A noninvasive scintigraphic technique was used to estimate enterogastric reflux and subsequent gastric evacuation of refluxate in 35 normal, healthy subjects and 55 patients previously treated by vagotomy or partial gastrectomy. Reflux was provoked by a milk drink and quantitated by counting 99Tcm-EHIDA activity within the gastric area during gamma camera imaging. Seven normal subjects (20%) showed reflux of 5-18% of initial activity (mean: 10%), with peak values occurring at 5-30 minutes (mean: 14 minutes) following the milk. Gastric evacuation of activity in these subjects was monoexponential (r = 0.993, T1/2 = 24.1 minutes). Reflux occurred more frequently than normal in patients with truncal vagotomy and drainage (22/28 patients) and partial gastrectomy (20/21 patients). All of 16 patients with Billroth II anastomoses exhibited reflux, which was excessive compared with refluxing normal subjects (mean: 25%; p less than 0.01) and occurred later into the study (mean: 34 minutes; p less than 0.01). Ten of 11 asymptomatic patients showed reflux of similar amounts of activity (mean: 21%) compared with 16 patients who complained of bile vomiting (mean: 22%). However, asymptomatic patients exhibited gastric evacuation of refluxate at a rate similar to that of refluxing normal subjects, while bile vomiters showed significant gastric retention of refluxate at 25-30 minutes following peak gastric activity (p less than 0.05). This result confirms that post-operative bile vomiting is essentially a problem of gastric emptying

    Gastro-oesophageal reflux (GOR) is commonly diagnosed in the neonatal population (DiPietro 1994), and generally causes few or no symptoms (Vandenplas 2009). Conversely, gastro-oesophageal reflux disease (GORD) refers to GOR that causes troublesome symptoms with or without complications such as damage to the oesophagus (Vandenplas 2009). Currently there is no evidence to support the range of measures recommended to help alleviate acid reflux experienced by infants. Non-nutritive sucking (NNS) has been used as an intervention to modulate neonatal state behaviours through its pacifying effects such as decrease infant fussiness and crying during feeds (Boiron 2007; Pickler 2004). To determine if NNS reduces GORD in preterm infants (less than 37 weeks' gestation) and low birth weight (less than 2500 g) infants, three months of age and less, with signs or symptoms suggestive of GORD, or infants with a diagnosis of GORD. We performed computerised searches of the electronic databases of the Cochrane Central Register of Controlled Trials (CENTRAL) (Issue 9, 2013), MEDLINE (1966 to September 2013), CINAHL (1982 to September 2013), and EMBASE (1988 to September 2013). We applied no language restrictions. Controlled trials using random or quasi-random allocation of preterm infants (less than 37 weeks' gestation) and low birth weight (less than 2500 g) infants three months of age and less with signs or symptoms suggestive of GORD, or infants with a diagnosis of GORD. We included studies reported only by abstracts, and cluster and cross-over randomised trials. Two review authors independently reviewed and selected trials from searches, assessed and rated study quality and extracted relevant data. We identified two studies from the initial search. After further review, we excluded both studies. We identified no studies examining the effects of NNS for GORD in preterm and low birth weight infants There was insufficient evidence to determine the effectiveness of NNS for GORD

Interpretation of 31 of 57 examinations done with usual scintiscan was not possible because of too high esophageal tracer retention. Only one case could not be interpreted with the modified technique. Gastroesophageal reflux was detected and quantified in this manner in 8 patients, 6 more than with the usual scintiscan. 7 of these 8 patients have had Heller procedure, 1 patient even combined with fundoplasty.

    It has been suggested that gastroesophageal reflux scintigraphy might be useful in assisting one in determining therapy for patients suspected of aspirating or becoming apneic secondary to gastroesophageal reflux. This, however, has not been our experience and in reviewing 23 patients with recurrent pneumonia and/or apnea who had gastroesophageal reflux scintigraphy, we were able to detect aspiration in only one. This was especially significant since 13 (59%) of these patients had demonstrable reflux, and of these, eight were treated successfully for suspected aspiration even though none was demonstrated isotopically. To be sure, the demonstration of pulmonary aspiration with gastroesophageal reflux scintigraphy had little influence on patient selection and response to therapy. For this reason we feel there is little justification in depending on the GRS for the specific purpose of trying to document pulmonary aspiration in infants and children who are refluxing. One of the more serious complications of gastroesophageal (GE) reflux is aspiration leading to recurrent pulmonary infections and/or apnea. However, it always has been difficult to demonstrate actual aspiration into the lungs, and to be sure, barium studies of the upper GI tract seldom reveal this complication. Recently, however, considerable interest has been generated in gastroesophageal scintigraphy (GRS) as a possible means of documenting such aspiration. Rationale for this stems from the fact that suspected patients can be studied over a longer period of time and in addition, delayed and overnight images can be obtained. However, our experience does not support GRS as being an adequate method for demonstrating aspiration. (orig.)

  5. Sex and Gender Differences in Gastroesophageal Reflux Disease

    It is important to understand sex and gender-related differences in gastroesophageal reflux disease (GERD) because gender-related biologic factors might lead to better prevention and therapy. Non-erosive reflux disease (NERD) affects more women than men. GERD symptoms are more frequent in patients with NERD than in those with reflux esophagitis. However, men suffer pathologic diseases such as reflux esophagitis, Barrett’s esophagus (BE), and esophageal adenocarcinoma (EAC) more frequently than women. The prevalence of reflux esophagitis is significantly increased with age in women, especially after their 50s. The mean age of EAC incidence in women is higher than in men, suggesting a role of estrogen in delaying the onset of BE and EAC. In a chronic rat reflux esophagitis model, nitric oxide was found to be an aggravating factor of esophageal injury in a male-predominant way. In addition, the expression of esophageal occludin, a tight junction protein that plays an important role in the esophageal defense mechanism, was up-regulated in women. This explains the male predominance of reflux esophagitis and delayed incidence of BE or EAC in women. Moreover, the symptoms such as heartburn, regurgitation, and extra-esophageal symptoms have been more frequently reported by women than by men, suggesting that sex and gender play a role in symptom perception. Differential sensitivity with augmented symptoms in women might have diagnostic and therapeutic influence. Furthermore, recent studies have suggested that hormone replacement therapy has a protective effect against esophageal cancer. However, an anti-inflammatory role of estrogen remains compelling, which means further study is necessary in this area. PMID:27703114

    Gastro-esophageal reflux (GER), particularly non-acid reflux, is common in infants and is a known cause of chronic respiratory symptoms in infancy. Recent guidelines recommended empirical acid suppression therapy and the head-up position in patients with suspected GER. However, the efficacy of the upright position in relieving GER and reflux-related respiratory symptoms in infants is unclear. We conducted this study to investigate the efficacy of the upright position on GER and reflux-related respiratory symptoms in infants with chronic respiratory symptoms. Thirty-two infants (21 male; median age, 5 months; range, 0 to 19 months) with unexplained chronic respiratory symptoms underwent multi-channel intraluminal esophageal impedance and pH monitoring. We retrospectively compared the frequencies of GER and reflux-related symptoms according to body position. A mean of 3.30 episodes of reflux per hour was detected. Overall, refluxes were more frequent during the postprandial period than the emptying period (3.77 vs. 2.79 episodes/hour, respectively; P=0.01). Although there was no significant difference in the total refluxes per hour between the upright and recumbent positions (6.12 vs. 3.77 episodes, P=0.10), reflux-related respiratory symptoms per reflux were significantly fewer in infants kept in an upright position than in a recumbent position during the postprandial period (3.07% vs. 14.75%, P=0.016). Non-acid reflux was the predominant type of reflux in infants, regardless of body position or meal time. The upright position may reduce reflux-related respiratory symptoms, rather than reflux frequency. Thus, it may be a useful non-pharmacological treatment for infantile GER disease resistant to acid suppressants.

    Proton pump inhibitors and laparoscopic anti-reflux surgery (LARS) offer long-term symptom control to patients with gastro-oesophageal reflux disease (GERD). To evaluate the process of 'normalisation' of the squamous epithelium morphology of the distal oesophagus on these therapies. In the LOTUS trial, 554 patients with chronic GERD were randomised to receive either esomeprazole (20-40 mg daily) or LARS. After 5 years, 372 patients remained in the study (esomeprazole, 192; LARS, 180). Biopsies were taken at the Z-line and 2 cm above, at baseline, 1, 3 and 5 years. A severity score was calculated based on: papillae elongation, basal cell hyperplasia, intercellular space dilatations and eosinophilic infiltration. The epithelial proliferative activity was assessed by Ki-67 immunohistochemistry. A gradual improvement in all variables over 5 years was noted in both groups, at both the Z-line and 2 cm above. The severity score decreased from baseline at each subsequent time point in both groups (P refluxate seems to play the predominant role in restoring tissue morphology. © 2017 John Wiley & Sons Ltd.

  15. SWEDISH CRIME FICTION AS SOCIALLY INVOLVED LITERATURE

    Directory of Open Access Journals (Sweden)

    Monika Samsel-Chojnacka

    2011-01-01

    Full Text Available Swedish crime novel has been transforming for many years to become more socially involved. The ambition of many writers is not only to entertain the readers but also to participating in the social debate, criticizing the political and economical system, focusing on important issues such as violence against women, exploitation of working class by the privileged ruling class, the problems of a modern family and the situation of immigrants. Since the moment when in the mid 60’s two journalists Maj Sjöwall and Per Wahlöö decided to use popular literature to spread social matters many other Swedish writers have decided to follow their way. Some of them are journalists – like Liza Marklund, Börge Hellström and Anders Roslund or Stieg Larsson. Their novels as well as the ones written by Henning Mannkel on Kurt Wallander have become crucial evidence of changes of Swedish society in the past twenty years. Modern Swedish crime fiction illustrates the population in the model fashion that is the reason why it can become one of the interests of the sociology of literature.

    2000-01-01

    Objective: The relationship between gastroesophageal reflux disease (GERD) and gastric emptying rate was investigated. Results of endoscopy, 24-hour esophageal pH monitoring were also evaluated. Methods: 15 patients were evaluated with endoscopy, pH monitoring and radionuclide gastric emptying. The results were compared with that of 17 control subjects. Correlations of gastric emptying rate and esophagitis, 24-hour pH monitoring between GERD patients and control subjects were also analyzed. Results: Liquid gastric emptying rate of GERD patients was significantly lower than that of control subjects at 15 and 30 min (P 0.05), but there exhibited a linear correlation between 50% solid emptying time and esophagus pH total score (r=0.643, P<0.05). Conclusions: The results indicate a delayed liquid and solid gastric emptying in GERD patients. There is a linear correlation between 50% solid emptying time and esophagus pH total score. Delayed gastric emptying may be an important factor in the pathogenesis of GERD

  17. Gastroesophageal Reflux Disease: Medical or Surgical Treatment?

    2009-01-01

    Full Text Available Background. Gastroesophageal reflux disease is a common condition with increasing prevalence worldwide. The disease encompasses a broad spectrum of clinical symptoms and disorders from simple heartburn without esophagitis to erosive esophagitis with severe complications, such as esophageal strictures and intestinal metaplasia. Diagnosis is based mainly on ambulatory esophageal pH testing and endoscopy. There has been a long-standing debate about the best treatment approach for this troublesome disease. Methods and Results. Medical treatment with PPIs has an excellent efficacy in reversing the symptoms of GERD, but they should be taken for life, and long-term side effects do exist. However, patients who desire a permanent cure and have severe complications or cannot tolerate long-term treatment with PPIs are candidates for surgical treatment. Laparoscopic antireflux surgery achieves a significant symptom control, increased patient satisfaction, and complete withdrawal of antireflux medications, in the majority of patients. Conclusion. Surgical treatment should be reserved mainly for young patients seeking permanent results. However, the choice of the treatment schedule should be individualized for every patient. It is up to the patient, the physician and the surgeon to decide the best treatment option for individual cases.

    1986-01-01

    An acid perfusion test, isotope scanning, endoscopy, and esophageal biopsy were performed in 101 patients with symptoms strongly suggestive of gastroesophageal reflux (GER) disease. A positive acid perfusion test within 30 min (APT) and within 5 min (TAPT) was found in 70.2% and 37.6% of the patients, respectively. A positive APT was found significantly more often in patients with than without endoscopic esophagitis, whereas a positive TAPT was found significantly more often in patients with severe symptoms than in patients with moderate symptoms, and in a significantly higher proportion of patients with than without GER by scintigraphy. Neither the APT nor the TAPT showed any dependency on the presence of histologic esophagitis. Most (97%) patients with a negative acid perfusion test, in addition to typical symptoms, also presented with scintigraphic, endoscopic, or histologic evidence of GER disease. Although it shows that the acid perfusion test, particularly when early positive, may serve as a weak predictor of the severity of GER disease, the present study gives little support to the test's clinical usefulness.

    Full Text Available Abstract Background Gastro-oesophageal reflux disease (GORD symptoms are common in asthma and have been extensively studied, but less so in the Asian continent. Reflux-associated respiratory symptoms (RARS have, in contrast, been little-studied globally. We report the prevalence of GORD symptoms and RARS in adult asthmatics, and their association with asthma severity and medication use. Methods A cross-sectional analytical study. A validated interviewer-administered GORD scale was used to assess frequency and severity of seven GORD symptoms. Subjects were consecutive asthmatics attending medical clinics. Controls were matched subjects without respiratory symptoms. Results The mean (SD composite GORD symptom score of asthmatics was significantly higher than controls (21.8 (17.2 versus 12.0 (7.6; P P Conclusions GORD symptoms and RARS were more prevalent in a cohort of Sri Lankan adult asthmatics compared to non-asthmatics. Increased prevalence of RARS is associated with both typical and atypical symptoms of GORD. Asthma disease and its severity, but not asthma medication, appear to influence presence of GORD symptoms.

  20. Processing Relative Clause Extractions in Swedish

    Full Text Available Relative clauses are considered strong islands for extraction across languages. Swedish comprises a well-known exception, allegedly allowing extraction from relative clauses (RCE, raising the possibility that island constraints may be subject to “deep variation” between languages. One alternative is that such exceptions are only illusory and represent “surface variation” attributable to independently motivated syntactic properties. Yet, to date, no surface account has proven tenable for Swedish RCEs. The present study uses eyetracking while reading to test whether the apparent acceptability of Swedish RCEs has any processing correlates at the point of filler integration compared to uncontroversial strong island violations. Experiment 1 tests RCE against licit that-clause extraction (TCE, illicit extraction from a non-restrictive relative clause (NRCE, and an intransitive control. For this, RCE was found to pattern similarly to TCE at the point of integration in early measures, but between TCE and NRCE in total durations. Experiment 2 uses RCE and extraction from a subject NP island (SRCE to test the hypothesis that only non-islands will show effects of implausible filler-verb dependencies. RCE showed sensitivity to the plausibility manipulation across measures at the first potential point of filler integration, whereas such effects were limited to late measures for SRCE. In addition, structural facilitation was seen across measures for RCE relative to SRCE. We propose that our results are compatible with RCEs being licit weak island extractions in Swedish, and that the overall picture speaks in favor of a surface rather than a deep variation approach to the lack of island effects in Swedish RCEs.

  1. Prevalence of footrot in Swedish slaughter lambs

    2011-04-01

    Full Text Available Abstract Background Footrot is a world-wide contagious disease in sheep and goats. It is an infection of the epidermis of the interdigital skin, and the germinal layers of the horn tissue of the feet. The first case of footrot in Swedish sheep was diagnosed in 2004. Due to difficulties in distinguishing benign footrot from early cases of virulent footrot and because there is no possibility for virulence testing of strains of Dichelobacter nodosus in Sweden, the diagnosis is based of the presence or absence of clinical signs of footrot in sheep flocks. Ever since the first diagnosed case the Swedish Animal Health Service has worked intensively to stop the spread of infection and control the disease at flock level. However, to continue this work effectively it is important to have knowledge about the distribution of the disease both nationally and regionally. Therefore, the aims of this study were to estimate the prevalence of footrot in Swedish lambs at abattoirs and to assess the geographical distribution of the disease. Methods A prevalence study on footrot in Swedish lambs was performed by visual examination of 2000 feet from 500 lambs submitted from six slaughter houses. Each foot was scored according to a 0 to 5 scoring system, where feet with score ≥2 were defined as having footrot. Moreover, samples from feet with footrot were examined for Dichelobacter nodosus by culture and PCR. Results The prevalence of footrot at the individual sheep level was 5.8%, and Dichelobacter nodosus was found by culture and PCR in 83% and 97% of the samples from feet with footrot, respectively. Some minor differences in geographical distribution of footrot were found in this study. Conclusions In a national context, the findings indicate that footrot is fairly common in Swedish slaughter lambs, and should be regarded seriously.

  2. The evaluation of gastroesophageal reflux before and after medical therapies

    Gastroesophageal scintigraphy is a quantitative technique that can be employed to detect and quantitate gastroesophageal reflux before and after the application of therapeutic modalities, including change in body position, bethanechol, atropine, antacids, and antacid-alginate compounds. Five groups of 10-15 patients each were studied before and after using each therapeutic modality and before and after atropine. The results were compared to the patient's symptomatology and to the acid reflux test. Gastroesophageal scintigraphy was performed following oral administration of 300 microCi 99mTc-sulfur colloid in 300 ml acidified orange juice. Thirty-second gamma camera images were obtained as the gastroesophageal gradient was increased from approximately 10 to 35 mm Hg at 5 mm Hg increments using an inflatable abdominal binder. Data were processed using a digital computer. Reflux was reduced by change in position from recumbent to upright, and by the use of subcutaneous bethanechol, oral antacid, or oral antacidalginate compound. Atropine increased reflux. Gastroesophageal scintigraphy is more sensitive than fluoroscopy, correlates well with clinical symptomatology, and is a reliable and convenient technique for the quantitative estimation of reflux before and after therapy

    Gastroesophageal reflux disease is one of the commonest chronic conditions in the western world and its prevalence is increasing worldwide. The discovery of the acid pocket explained the paradox of acid reflux occurring more frequently in the postprandial period despite intragastric acidity being low due to the buffering effect of the meal. The acid pocket was first described in 2001 when it was detected as an area of low pH immediately distal to the cardia using dual pH electrode pull-through studies 15 minutes after a meal. It was hypothesized that there was a local pocket of acid close to the gastroesophageal junction that escapes the buffering effect of the meal, and that this is the source of postprandial acidic reflux. The presence of the acid pocket has been confirmed in other studies using different techniques including high-resolution pHmetry, Bravo capsule, magnetic resonance imaging, and scintigraphy. This review aims to describe what we know about the acid pocket including its length, volume, fluid constituents, and its relationship to the lower esophageal sphincter and squamocolumnar junction. We will discuss the possible mechanisms that lead to the formation of the acid pocket and examine what differences exist in patients who suffer from acid reflux. Treatments for reflux disease that affect the acid pocket will also be discussed.

    Lung transplantation is one of the highest risk solid organ transplant modalities. Recent studies have demonstrated a relationship between gastroesophageal reflux disease (GERD) and lung transplant outcomes, including acute and chronic rejection. The aim of this review is to discuss the pathophysiology, evaluation, and management of GERD in lung transplantation, as informed by the most recent publications in the field. The pathophysiology of reflux-induced lung injury includes the effects of aspiration and local immunomodulation in the development of pulmonary decline and histologic rejection, as reflective of allograft injury. Modalities of reflux and esophageal assessment, including ambulatory pH testing, impedance, and esophageal manometry, are discussed, as well as timing of these evaluations relative to transplantation. Finally, antireflux treatments are reviewed, including medical acid suppression and surgical fundoplication, as well as the safety, efficacy, and timing of such treatments relative to transplantation. Our review of the data supports an association between GERD and allograft injury, encouraging a strategy of early diagnosis and aggressive reflux management in lung transplant recipients to improve transplant outcomes. Further studies are needed to explore additional objective measures of reflux and aspiration, better compare medical and surgical antireflux treatment options, extend follow-up times to capture longer-term clinical outcomes, and investigate newer interventions including minimally invasive surgery and advanced endoscopic techniques.

    Gastroesophageal reflux disease is a common disorder affecting children worldwide. The objective of this study is to report our experience on the accuracy of tests used for the diagnosis ofgastroesophageal reflux disease with emphasis on the advantages and disadvantages of each of them. This study took place in the Pediatric Gastroenterology Division, Department of Pediatrics, College of Medicine and King Khalid University Hospital, Riyadh, Kingdom of Saudi Arabia, during the period of 1994 through to 1999. Results of barium meal, 24-hour esophageal pH monitoring, endoscopy, and gastrointestinal scintigraphy are analyzed and compared in children with and without gastroesophageal reflux disease. One hundred and forty-four children were investigated. The diagnosis was confirmed in 85 and excluded in 59 children, who will be considered as patients without gastroesophageal reflux disease. The results of barium meal, 24 hour pH monitoring, endoscopy, and gastrointestinal scintigraphy were positive in 80%, 78%, 92%, and 70% of the patients with gastroesophageal disease. The same studies were falsely positive in 29%, 9%, 19%, and 0% of those without gastroesophageal reflux disease. Esophageal pH was the most specific diagnostic study (91%), whereas endoscopy was the most sensitive (92%) and had the best positive predictive value (95%). The results of this study are similar to reports from other parts of the world. It is stressed that all procedures have important advantages and disadvantages indicating that the selection of procedures should be individualized and based on the clinical situation. (author)

    Although gastroesophageal reflux disease (GERD) is a common disorder in Western countries, with a significant impact on quality of life and healthcare costs, the mechanisms involved in the pathogenesis of symptoms remain to be fully elucidated. GERD symptoms and complications may result from a multifactorial mechanism, in which acid and acid-pepsin are the important noxious factors involved. Prolonged contact of the esophageal mucosa with the refluxed content, probably caused by a defective anti-reflux barrier and luminal clearance mechanisms, would appear to be responsible for macroscopically detectable injury to the esophageal squamous epithelium. Receptors on acid-sensitive nerve endings may play a role in nociception and esophageal sensitivity, as suggested in animal models of chronic acid exposure. Meanwhile, specific cytokine and chemokine profiles would appear to underlie the various esophageal phenotypes of GERD, explaining, in part, the genesis of esophagitis in a subset of patients. Despite these findings, which show a significant production of inflammatory mediators and neurotransmitters in the pathogenesis of GERD, the relationship between the hypersensitivity and esophageal inflammation is not clear. Moreover, the large majority of GERD patients (up to 70%) do not develop esophageal erosions, a variant of the condition called non-erosive reflux disease. This summary aims to explore the inflammatory pathway involved in GERD pathogenesis, to better understand the possible distinction between erosive and non-erosive reflux disease patients and to provide new therapeutic approaches.

    While delayed solid gastric emptying (GE) has been reported in patients with gastroesophageal reflux (GER), the relationship of GE to daytime and/or nighttime reflux patterns, and the severity of endoscopic esophagitis are unknown. The authors measured GE in a study population of symptomatic patients (n=33) with abnormal 24 hour pH monitoring (24 hr pH). The study population was divided into two groups by esophagoscopy; those with (E+=22); and 2) those without (E-=11) erosive esophagitis and/or Barrett's esophagus. GE was measured in all patients and in 15 normal volunteers (NL) by the in vivo labelling of chicken liver with Tc-99m-SC, which was in turn diced into 1 cm. cubes and given in 7 1/2 oz. of beef stew. Upright one minute anterior and posterior digital images were obtained every 15 min. for 2.5 hours. 24 hour pH was divided into daytime (upright) and nighttime (supine) segments, and acid exposure was defined as % time pH < 4 for that posture. There was no correlation between GE T 1/2 and acid exposure, daytime or nighttime, for the patient population as a whole. However, patients with the longest GE T1/2 tended to have severe daytime reflux. The authors rarely found delayed solid food gastric emptying in patients with reflux; moreover, they found no association between GE and either diurnal reflux patterns on 24 hr pH or the severity of endoscopic esophagitis

    This study was designed to determine the protective effect of Rumex Aquaticus Herba extracts containing quercetin-3-β-D-glucuronopyranoside (ECQ) on experimental reflux esophagitis. Reflux esophagitis was induced by surgical procedure. The rats were divided into seven groups, namely normal group, control group, ECQ (1, 3, 10, 30 mg/kg) group and omeprazole (30 mg/kg) group. ECQ and omeprazole groups received intraduodenal administration. The Rats were starved for 24 hours before the experiments, but were freely allowed to drink water. ECQ group attenuated the gross esophagitis significantly compared to that treated with omeprazole in a dose-dependent manner. ECQ decreased the volume of gastric juice and increased the gastric pH, which are similar to those of omeprazole group. In addition, ECQ inhibited the acid output effectively in reflux esophagitis. Significantly increased amounts of malondialdehyde (MDA), myeloperoxidase (MPO) activity and the mucosal depletion of reduced glutathione (GSH) were observed in the reflux esophagitis. ECQ administration attenuated the decrement of the GSH levels and affected the MDA levels and MPO activity. These results suggest that the ECQ has a protective effect which may be attributed to its multiple effects including anti-secretory, anti-oxidative and anti-inflammatory actions on reflux esophagitis in rats.

    Although exhaled breath condensate (EBC) pH has been identified as an "emerging" biomarker of interest for asthma clinical trials, the clinical determinants of EBC pH remain poorly understood. Other studies have associated acid reflux-induced respiratory symptoms, for example, cough, with transient acidification of EBC. We sought to determine the clinical and physiologic correlates of EBC acidification in a highly characterized sample of children with poorly controlled asthma. We hypothesized that (1) children with asymptomatic gastroesophageal reflux determined by 24-hour esophageal pH monitoring would have a lower EBC pH than children without gastroesophageal reflux, (2) treatment with lansoprazole would alter EBC pH in those children, and (3) EBC acidification would be associated with increased asthma symptoms, poorer asthma control and quality of life, and increased formation of breath nitrogen oxides (NOx). A total of 110 children, age range 6 to 17 years, with poor asthma control and esophageal pH data enrolled in the Study of Acid Reflux in Children with Asthma (NCT00442013) were included. Children submitted EBC samples for pH and NOx measurement at randomization and at study weeks 8, 16, and 24. Serial EBC pH measurements failed to distinguish asymptomatic gastroesophageal reflux and was not associated with breath NOx formation. EBC pH also did not discriminate asthma characteristics such as medication and health care utilization, pulmonary function, and asthma control and quality of life both at baseline and across the study period. Despite the relative ease of EBC collection, EBC pH as a biomarker does not provide useful information of children with asthma who were enrolled in asthma clinical trials.

    2006-01-01

    There are many articles about the role of barium esophagography for the diagnosis of gastroesophageal reflux disease. However, there are only rare articles reporting on laryngopharyngeal reflux disease. The purpose of this study is to evaluate the usefulness of performing esophagography with the water-siphon test as an initial screening test for patients with suspected laryngopharyngeal reflux. From October 2002 to December 2004, barium esophagography with the water-siphon test was performed for 707 patients who had the typical symptoms and telescopic findings of laryngopharyngeal reflux. The results of the 707 esophagograms (the group with laryngopharyngeal reflux) were compared with those of 122 patients who were confirmed as having gastroesophageal reflux upon performing pH-metry (the group with gastroesophageal reflux) and the 324 patients without laryngopharyngeal reflux symptoms (the control group). The results of the water-siphon test were classified into normal, mild, moderate and severe degrees of gastroesophageal reflux. On the water-siphon test for the laryngopharyneal reflux group patients, 71 patients had normal (10.0%), 207 had mild (29.2%), 201 had moderate (28.4%) and 228 had severe (32.2%) degrees of reflux. The positive rates of the water-siphon test were 90.0%, 89.3% and 54.6% for the groups with laryngopharyngeal reflux, gastroesophageal reflux and the control group, respectively. A statistically significant difference was observed between the group with laryngopharyngeal reflux and the control group, and between the group with gastroesophageal reflux and the control group, respectively (ρ < 0.05). Esophagography with the water-siphon test is useful as an initial screening test for laryngopharyngeal reflux disease

A statistically significant difference was observed between the group with laryngopharyngeal reflux and the control group, and between the group with gastroesophageal reflux and the control group, respectively ({rho} < 0.05). Esophagography with the water-siphon test is useful as an initial screening test for laryngopharyngeal reflux disease.

    Esophageal reflux symptom has been reported as common in patients with subtotal gastrectomy. Management of postoperative esophageal reflux symptom is not satisfactory. The aim of this study is to investigate prevalence of esophageal reflux symptom after subtotal gastrectomy and assess factors affecting esophageal reflux symptom in subtotal gastrectomy patients. We prospectively enrolled 100 consecutive patients with subtotal gastrectomy who were regularly followed up by endoscopic examination. Acid secretory capacity was assessed by measuring messenger RNA (mRNA) expression of H + /K + -adenosine triphosphatase (ATPase) via real-time polymerase chain reaction (PCR) in biopsy specimens. In total, 47 % of patients had typical esophageal reflux symptom, where heartburn or regurgitation was experienced at least weekly. Age, sex, body mass index, and type of reconstruction did not differ between esophageal reflux and non-esophageal-reflux groups. The esophageal reflux group had longer duration from time of operation until study (median 5.0 versus 3.6 years; P = 0.017). Hill grade for gastroesophageal (GE) flap valve was higher in the esophageal reflux group than in the non-esophageal-reflux group (P = 0.027). H + /K + -ATPase mRNA expression was higher in the esophageal reflux group than in the non-esophageal-reflux group [3967.6 (± 7583.7) versus 896.2 (± 1456.0); P = 0.006]. Multivariate analysis revealed that postoperative duration, H + /K + -ATPase mRNA expression level, and GE flap valve disruption were significantly associated with esophageal reflux symptom development. Esophageal reflux symptom is common in patients after subtotal gastrectomy, possibly because of anti-reflux-barrier impairment and preservation of acid secretory capacity following surgery. Optimal acid suppression may be helpful in managing postoperative esophageal reflux symptom.

    The objective of the present study was to determine if there is correlation between signs of reflux laryngitis (RL) and reflux oesophagitis (RE) in patients with gastro-oesophageal reflux disease (GORD) symptoms. Laryngeal photography obtained from patients during oesophagogastroduodenoscopy were examined by two otolaryngologists experienced in the field of extra-oesophageal reflux regarding the presence and severity of RL. The presence of RE was evaluated by gastroenterologist. Smokers, heavy drinkers and patients with bronchial asthma were excluded from the statistical analysis. A total of 681 patients were analysed. RL was diagnosed in 367 (53.9%) cases, of whom 182 patients had mild, 118 moderate and 67 severe (Reflux Finding Score > 7) RL. RE was diagnosed in 103 (28.1%) patients with RL and in 80 (25.7%) patients without RL. Neither the difference between the overall group of patients with RL and those without (OR 1.141, 95% CI 0.811-1.605, p = 0.448), nor the differences between the respective subgroups of patients with mild, moderate and severe RL and those without RL were statistically significant. The OR and 95% CI for mild, moderate and severe RL were 1.042, 95% CI 0.712-1.526, p = 0.834, 1.182, 95% CI 0.764-1.831, p = 0.453 and 1.0, 95% CI 0.566-1.766, p = 0.999 respectively. It can be concluded that there is no correlation between RL and RE in patients with GORD symptoms. © Copyright by Società Italiana di Otorinolaringologia e Chirurgia Cervico-Facciale, Rome, Italy.

    The oesophago-gastric junction functions as an anti-reflux barrier preventing increased exposure of the oesophageal mucosa to gastric contents. Failure of this anti-reflux barrier results in gastro-oesophageal reflux disease, and may lead to complications such as oesophagitis, Barrett's oesophagus

    Thirty-seven adults with gastroesophageal reflux were explored by oesophageal scintigraphy and pH monitoring (three hours postprandial). Scintigraphy was less frequently positive than pH test in gastroesophageal reflux (81% versus 57%) with a significant difference. It is suggested that postprandial pH monitoring is reliable in the initial assessment of symptomatic gastroesophageal reflux.

    Gastro-oesophageal reflux disease (GORD) is a common condition with 3% to 33% of people from different parts of the world suffering from GORD. There is considerable uncertainty about whether people with GORD should receive an operation or medical treatment for controlling the condition. To assess the benefits and harms of laparoscopic fundoplication versus medical treatment for people with gastro-oesophageal reflux disease. We searched the Cochrane Upper Gastrointestinal and Pancreatic Diseases Group (UGPD) Trials Register (June 2015), Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library Issue 6, 2015), Ovid MEDLINE (1966 to June 2015), and EMBASE (1980 to June 2015) to identify randomised controlled trials. We also searched the references of included trials to identify further trials. We considered only randomised controlled trials (RCT) comparing laparoscopic fundoplication with medical treatment in people with GORD irrespective of language, blinding, or publication status for inclusion in the review. Two review authors independently identified trials and independently extracted data. We calculated the risk ratio (RR) or standardised mean difference (SMD) with 95% confidence intervals (CI) using both fixed-effect and random-effects models with RevMan 5 based on available case analysis. Four studies met the inclusion criteria for the review, and provided information on one or more outcomes for the review. A total of 1160 participants in the four RCTs were either randomly assigned to laparoscopic fundoplication (589 participants) or medical treatment with proton pump inhibitors (571 participants). All the trials included participants who had had reflux symptoms for at least six months and had received long-term acid suppressive therapy. All the trials included only participants who could undergo surgery if randomised to the surgery arm. All of the trials were at high risk of bias. The overall quality of evidence was low or very low.

    In a study comprising 100 patients referred to a surgical clinic with symptons suggestive of gastro-oesophageal reflux disease, the value of different diagnostic procedures was investigated. Positive acid perfusion and 24-h pH tests were the commonest findings. Forty-nine per cent showed normal oesophageal mucosa or diffuse oesophagitis at endoscopy. The severity of heartburn and regurgitation did not differ between patients with normal oesophageal mucosa and oesophagitis of various severities. The severity of macroscopic oesophagitis was significantly corelated to the total reflux time, the presence of reflux or a hiatal hernia at radiology, an open cardia or reflux at endoscopy, pressure transmission or reflux, and low lower oesophageal sphincter pressure at manometry. Gastric hypersecretion was found in 66% of the patients. Gastric acid secretion was not correlated to the severity of oesophagitis or to the findings at 24-h pH test. In patients with severe oesophagitis the sensivity for radiologic, manometric and endoscopic signs of incompetence of the gastro-oesophageal junction was 94%.

    MR urography has the potential to significantly improve our understanding of the relationship between reflux nephropathy, pyelonephritis, vesicoureteric reflux and renal dysplasia. MR urography utilizes multiple parameters to assess both renal anatomy and function and provides a more complete characterization of acquired and congenital disease. Pyelonephritis and renal scarring can be distinguished by assessing the parenchymal contours and signal intensity. Characteristic imaging features of renal dysplasia include small size, subcortical cysts, disorganized architecture, decreased and patchy contrast enhancement as well as a dysmorphic pelvicalyceal system. Because of its ability to subdivide and categorize this heterogeneous group of disorders, it seems inevitable that MR urography will replace DMSA renal scintigraphy as the gold standard for assessment of pyelonephritis and renal scarring. MR urography will contribute to our understanding of renal dysplasia and its relationship to reflux nephropathy. (orig.)

    Full Text Available The clinical presentation of noncystic fibrosis bronchiectasis may be complicated by concomitant conditions, including gastro-oesophageal reflux (GOR. Increased acidic GOR is principally caused by gastro-oesophageal junction incompetence and may arise from lower oesophageal sphincter hypotension, including transient relaxations, hiatus hernia, and oesophageal dysmotility. Specific pathophysiological features which are characteristic of respiratory diseases including coughing may further increase the risk of GOR in bronchiectasis. Reflux may impact on lung disease severity by two mechanisms, reflex bronchoconstriction and pulmonary microaspiration. Symptomatic and clinically silent reflux has been detected in bronchiectasis, with the prevalence of 26 to 75%. The cause and effect relationship has not been established, but preliminary reports suggest that GOR may influence the severity of bronchiectasis. Further studies examining the implications of GOR in this condition, including its effect across the disease spectrum using a combination of diagnostic tools, will clarify the clinical significance of this comorbidity.

    A detailed critique of objective measurements of gastroesophageal reflux disease (GERD) would improve management of patients suspecting of having reflux, leading to rational selection of treatment and better outcomes. Many diagnostic tests for GERD have been developed over the past decades. We analyze their development, positive- and negative-predictive values, and ability to predict response to treatment. These features are important for development of medical, surgical, and endoscopic therapies for GERD. We discuss the value of available diagnostic tests and review their role in management of patients with persistent reflux symptoms despite adequate medical or surgical treatment. This is becoming a significant health economic problem, due to the widespread use of proton pump inhibitors. GERD is believed to cause nonesophageal symptoms, such as those provoked by ear, nose, throat, or respiratory disorders. We analyze the value of GERD diagnostic tests in evaluation of these troublesome, nonesophageal symptoms. Copyright © 2018 AGA Institute. Published by Elsevier Inc. All rights reserved.

    Gastroesophageal reflux disease (GERD) is prevalent in Asia as well as in Western countries. Sleep disturbance and breathing disorders during sleep are becoming increasingly prevalent, and they are commonly associated with GERD. The relationship between GERD and obstructive sleep apnea (OSA) is still questionable, and it has expanded to include Barrett's esophagus. Nocturnal gastroesophageal reflux (nGER) symptoms might be clinically important in the explanation of this association. The therapy for reflux symptoms has resulted in improved subjective sleep parameters and enhanced sleep quality, thus supporting a direct relationship between GERD and sleep disturbance. This review discusses the epidemiology of sleep disturbances in GERD patients; the causative relationship between GERD and OSA, even though it remains an area of controversy; and the possible role of nGER in sleep problems. It also provides an update on the current state of knowledge linking GERD and sleep. © 2016 New York Academy of Sciences.

    The voiding cystourethrogram (VCUG) is a widely used study to define lower urinary tract anatomy and to diagnose vesicoureteric reflux (VUR) in children. We examine the technical advances in the VCUG and other examinations for reflux that have reduced radiation exposure of children, and we give recommendations for the use of imaging studies in four groups of children: (1) children with urinary tract infection, (2) siblings of patients with VUR, (3) infants with antenatal hydronephrosis (ANH), and (4) children with a solitary functioning kidney. By performing examinations with little to no radiation, carefully selecting only the children who need imaging studies and judiciously timing follow-up examinations, we can reduce the radiation exposure of children being studied for reflux.

    The paper describes a project carried out at Dawes Lane coking plant (in Scunthorpe, UK) to access current performance of the batch reflux system with respect to the operation of personnel and to recommend a solution to eliminate naphthalene blockage and problems previously caused by the use of hot debenzolised oil (DBO) as make-up. A successful solution was found and implemented. The benzole product now being produced is within specification and regularly achieves the composition produced by the previous hot reflux system (83% benzole, 7% naphthalene) with an addition reduction in wash oil usage of 20%. Problems of naphthalene blockages in reflux pipework have been cured. The expenses on the project were small. The paper was presented at a COMA meeting at Monckton Coke Ovens on 19 May 2005. 6 figs.

    1998-01-01

    Full Text Available Symptomatic gastroesophageal reflux is a common complication of pregnancy and lactation. However, the safety of many effective medical therapies, including oral proton pump inhibitors, has not been well defined. The administration of oral omeprazole to a 41-year-old female during the third trimester of pregnancy, after ranitidine and cisapride failed to control her refractory gastroesophageal reflux, is reported. No adverse fetal effects were apparent, and the patient elected to continue omeprazole therapy (20 mg/day while breastfeeding. Peak omeprazole concentrations in breast milk (58 nM, 3 h after ingestion were less than 7% of the peak serum concentration (950 nM at 4 h, indicating minimal secretion. Although omeprazole is a potentially useful therapy for refractory gastroesophageal reflux during pregnancy and lactation, further data are needed to define better its safety and efficacy.

    2015-01-01

    Comprehensive guidelines for the diagnosis and management of gastro-esophageal reflux (GER) and GER disease (GERD) were developed by the European and North American Societies for Pediatric Gastroenterology, Hepatology and Nutrition. GERD is reflux associated with troublesome symptoms or complications. The recognition of GER and GERD is relevant to implement best management practices. A conservative management is indicated in infants with uncomplicated physiologic reflux. Children with GERD may benefit from further evaluation and treatment. Since the publications of the European and North American Societies for Pediatric Gastroenterology, Hepatology and Nutrition guidelines in 2009, no important novelties in drug treatment have been reported. Innovations are mainly restricted to the management of regurgitation in infants. During the last 5 years, pros and cons of multichannel intraluminal impedance have been highlighted. However, overall 'not much has changed' in the diagnosis and management of GER and GERD in infants and children.

    Full Text Available Vesicoureteral reflux (VUR is a common congenital renal tract anomaly in children. Reports from Sudan are scanty. We report the characteristics, presentation and outcome of primary VUR in a tertiary care hospital. The records of 30 patients (16 males; 53% followed-up between January 2004 and December 2010 were reviewed. The mean age at the time of diagnosis was 4 ± 3.9 years and 47% were <2 years of age. Renal ultrasound scan (USS failed to predict VUR in 17% of the patients. On voiding cysturethrogram (VCUG, VUR was bilateral in 57% and severe grade in 64%. Grades were not significantly associated with age, gender or site of VUR. Initial dimercaptosuccinic acid radionuclide scan showed renal damage in 61.5% of the patients. Renal damage was significantly associated with female gender and severe VUR, but not with age of onset or history of urinary tract infection (UTI. Thirteen patients (43.3% presented with acute UTI, eight (26.6% with non-specific urinary tract symptoms and nine (30% with persistently elevated serum creatinine. Urine cultures were positive in 73% of patients, and E. coli was the most common pathogen. Renal impairment at presentation was significantly associated with bilateral severe VUR and history of UTI but not age or gender. After a mean follow-up period of 1.78 years (6 months to 5 years, 70% of patients remained with normal renal function and 30% progressed to chronic kidney disease; two of them died. In conclusion, our data is different from many studies. Features of primary VUR in Sudanese children are late age of onset, equal gender affection and predominance of severe grade. Presentation is associated with a high rate of UTI, renal damage and advanced renal impairment. Measures to improve early detection and treatment of VUR may reduce the risk of kidney damage.

Randomized controlled study. Suez Canal University Hospital, Ismalia, Egypt. A total of 212 patients with symptoms of LPRD. Patients were evaluated by laryngoscopy, ambulatory pH monitoring for 24 hours, and HPSA testing. Esomeprazole magnesium as a monotherapy was evaluated vs triple therapy in patients with HP infection. To determine the incidence of HPSA in patients with LPRD, and to make a comparison of 2 treatment regimens that have been used based on the presence or absence of HPSA positivity in patients with LPRD. Persistent dry cough and a feeling of a lump in the throat (globus sensation) were the most frequent symptoms of LPRD, while posterior laryngeal inflammation was the main laryngoscopic finding. Results from the HPSA test were positive in 57% of the studied group. Patients with negative HPSA were treated with esomeprazole as single modality with a reported improvement score of 96.6%. Patients with positive HPSA test results were divided into 2 groups: 1 received only esomeprazole, with reported improvement in 40%, whereas the second group was treated with esomeprazole, plus amoxicillin sodium and clarithromycin (triple therapy) and reported a 90% incidence of symptom improvement. The incidence of HP infection in patients with LPRD in our study was 57%. Triple therapy showed a higher cure rate in patients with HPSA-positive test results.

    A prospective randomized study was done on 45 patients to evaluate the effectiveness of the Hill, Nissen or Belsey anti-reflux procedure. All patients had symptoms of GE reflux unresponsive to medical therapy, a + standard acid reflux test (SART), and esophagitis (38/45) or + Burnstein test (7/45). Esophageal symptomatic, radiographic, manometric and pH (SART and 24-hr monitoring) evaluation was done pre- and 154 days (ave.) postsurgery. All procedures improved the symptoms of pyrosis. The best improvement was seen after the Nissen repair. All procedures increased the distal esophageal sphincter (DES) pressures over preoperative levels. The Nissen and Belsey increased it more than the Hill. Sphincter length and dynamics remained unchanged. The Nissen procedure placed more of the manometric sphincter below the respiratory inversion point in the positive pressure environment of the abdomen. The esophageal length was increased by the Nissen and Hill repairs. This was thought to account for the high incidence of temporary postsurgery dysphagia following the Nissen and Hill repairs and the lower incidence following the Belsey repair. Reflux was most effectively prevented by the Nissen repair, as shown by the SART and the 24-hr esophageal pH monitoring, a sensitive measurement of frequency and duration of reflux. The average length of hospital stay was 20 days for Belsey and 12 days for both Nissen and Hill procedure. Postsurgery complications were more common following the thoracic than the abdominal approach. Ability to vomit postrepair was greatest with the Hill and least with the Belsey and Nissen repair. All procedures temporarily increased amount of flatus. It is concluded that the Nissen repair best controls reflux and its symptoms by providing the greatest increase in DES pressure and placing more of the sphincter in the positive abdominal environment. This is accomplished with the lowest morbidity but at the expense of temporary postoperative dysphagia and a 50

    Most patients with gastroesophageal reflux disease experience symptomatic relapse after stopping acid-suppressive medication. The aim of this study was to compare willingness to continue treatment with esomeprazole on-demand versus continuous maintenance therapy for symptom control in patients with non-erosive reflux disease (NERD) after 6 months. This multicenter, open-label, randomized, parallel-group study enrolled adults with NERD who were heartburn-free after 4 weeks' treatment with esomeprazole 20 mg daily. Patients received esomeprazole 20 mg daily continuously or on-demand for 6 months. The primary variable was discontinuation due to unsatisfactory treatment. On-demand treatment was considered non-inferior if the upper limit of the one-sided 95 % confidence interval (CI) for the difference between treatments was reflux esophagitis versus none in the continuous group (P Reflux dimension was also improved for continuous versus on-demand treatment. Esomeprazole was well tolerated. In terms of willingness to continue treatment, on-demand treatment with esomeprazole 20 mg was non-inferior to continuous maintenance treatment and reduced medication usage in patients with NERD who had achieved symptom control with initial esomeprazole treatment.

    - Gastroesophageal reflux disease is the most common esophageal disorder in pediatrics. - The aim of this study was to compare reflux parameters of typical and atypical symptoms of gastroesophageal reflux disease using 24-hour esophageal pH monitoring and multichannel intraluminal impedance in pediatric population. - In this prospective study, 43 patients aged less than 18 year with suspected gastroesophageal reflux disease were enrolled. The patients were divided into two groups based on the main presenting symptoms (typical versus atypical). Twenty four-hour pH monitoring and multichannel intraluminal impedance were performed in all the patients for comparing these two group regarding association of symptoms and reflux. Number of refluxes, pH related reflux, total reflux time, reflux more than 5 minutes, longest time of the reflux, lowest pH at reflux, reflux index were recorded and compared. Data comparison was done using SPSS. - The mean age of the patients was 5.7±3.4 years and 65.1% were male. Out of 43 patients 24 cases had typical symptoms and 19 had atypical symptoms. The mean reflux events detected by multichannel intraluminal impedance was more than mean reflux events detected by pH monitoring (308.4±115.8 vs 69.7±66.6) with P value of 0.037, which is statistically significant. The mean symptom index and symptom association probability were 35.01% ± 20.78% and 86.42% ± 25.79%, respectively in multichannel intraluminal impedance versus 12.73% ± 12.48% and 45.16% ± 42.29% in pH monitoring (P value reflux was 46.26±47.16 and 30.9±22.09 for atypical and typical symptoms respectively. The mean symptom index was 18.12% ± 13.101% and 8.30% ± 10.301% in atypical and typical symptoms respectively (P=0.034). Bolus clearance was longer in atypical symptoms compared typical symptoms(Preflux was found in children with atypical symptoms of reflux. Longer duration of bolus clearance was found in group with atypical symptoms of reflux.

    The relationship between chronic obstructive pulmonary disease (COPD) exacerbations and gastroesophageal reflux (GER) has been investigated less than asthma-GER. We aimed to evaluate the presence of GER in patients with COPD and its impact on exacerbations. We included 24 patients with stable mild-moderate stage COPD and 19 volunteers as the control group. We conducted a gastroesophageal reflux disease (GERD) symptom questionnaire, gastroscopy, manometry, and an ambulatory 24-h pH-impedance study. According to the GERD questionnaire, only 5 (20.8%) patients with COPD had typical GER symptoms. According to the 24-h pH-impedance study, the mean DeMeester score (DMS) was 38.1 ± 34.6 in the COPD group and 13.3 ± 16.8 in the control group (p = 0.01). The acid reflux (DMS > 14.7) rate was higher in patients with COPD than in controls (73.9% vs 26.3%, p = 0.01). The symptom association probability positivity rate was 17.4% (n = 4) in the COPD group, which was similar to the controls (p = 0.11). The mean proximal extension rate of reflux (Z 17 cm) was 26.4 ± 12.9% in the COPD group. The proximal extent of reflux was positively correlated with the number of COPD exacerbations per year (p = 0.03, r = 0.448). In the motility results, only 2 (20%) patients in the control group had a minor motility disorder. Seventeen (70.8%) patients in the COPD group had a minor motility disorder, and 4 (16.7%) had major motility disorders (p gastroesophageal reflux was frequent in patients with COPD, but only a quarter had typical reflux symptoms. The proximal extent of reflux may trigger frequent exacerbations of COPD. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Gastroesophageal reflux disease (GERD) is a highly prevalent gastrointestinal disorder. Proton pump inhibitors have profoundly revolutionized the treatment of GERD. However, several areas of unmet need persist despite marked improvements in the therapeutic management of GERD. These include the advanced grades of erosive esophagitis, nonerosive reflux disease, maintenance treatment of erosive esophagitis, refractory GERD, postprandial heartburn, atypical and extraesophageal manifestations of GERD, Barrett’s esophagus, chronic protein pump inhibitor treatment, and post-bariatric surgery GERD. Consequently, any future development of novel therapeutic modalities for GERD (medical, endoscopic, or surgical), would likely focus on the aforementioned areas of unmet need. PMID:26130628

    Full Text Available This paper describes a shortcut procedure for batch distillation simulation with a variable reflux policy. The procedure starts from a shortcut method developed by Sundaram and Evans in 1993 and uses an iterative cycle to calculate the reflux ratio at each moment. The functional relationship between the concentrations at the bottom and the dome is evaluated using the Fenske equation and is complemented with the equations proposed by Underwood and Gilliland. The results of this procedure are consistent with those obtained using a fast method widely validated in the relevant literature.

    Full Text Available Idiopathic pulmonary fibrosis (IPF is a dreaded disease of uncertain etiology and no available cure. It is still unclear if a causal relationship exists between gastro-esophageal reflux (GER and IPF, but studies have shown an increased prevalence of acid reflux in patients with IPF. We describe a patient with achalasia and GER who went on to develop IPF. She underwent a rapidly worsening course punctuated by acute exacerbations of IPF, despite best efforts to manage the acid GER. We also reviewed the literature on the role of GER in the etiology and progression of IPF and the impact of antireflux measures on its course.

    2017-12-01

    Gastroesophageal reflux disease (GERD), which is common in many communities, is associated with structural factors, eating habits, and the use of certain drugs. The use of such drugs can lead to the emergence of GERD and can also exacerbate existing reflux symptoms. These drugs can contribute to GERD by directly causing mucosal damage, by reducing lower esophageal sphincter pressure (LESP), or by affecting esophagogastric motility. In this article, we report our investigation of the relationships between GERD and medications within the scope of the "Turkish GERD Consensus Group." For the medication groups for which sufficient data were obtained (Figure 1), a systematic literature review in English was conducted using the keywords "gastroesophageal reflux" [MeSH Terms] and "anti-inflammatory agents, non-steroidal" [MeSH Terms], "gastroesophageal reflux" [MeSH Terms] and "acetylsalicylic acid" [MeSH Terms], "gastroesophageal reflux" [All Fields] and "estrogenic agents" [All Fields], "gastroesophageal reflux" [All Fields] and "progesterones" [All Fields], "gastroesophageal reflux" [All Fields] and "hormone replacement therapy" [All Fields], "gastroesophageal reflux" [MeSH Terms] and "diphosphonates" [MeSH Terms] OR "diphosphonates" [All Fields], "calcium channel blockers" [MeSH Terms] and "gastroesophageal reflux" [MeSH Terms], "gastroesophageal reflux" [MeSH Terms] and "nitrates" [MeSH Terms], "gastroesophageal reflux" [MeSH Terms] and "antidepressive agents" [MeSH Terms], "gastroesophageal reflux" [MeSH Terms] and "benzodiazepines" [MeSH Terms] and "hypnotic drugs" [MeSH Terms], "gastroesophageal reflux" [MeSH Terms] and "cholinergic antagonists" [MeSH Terms], "gastroesophageal reflux" [MeSH Terms] and "theophylline" [MeSH Terms], and "gastroesophageal reflux [MeSH Terms] AND "anti-asthmatic agents" [MeSH Terms].

    Full Text Available Aim: We retrospectively reviewed videourodynamic outcomes in children with primary vesicoureteral reflux. The aim of this study to evaluate the relationship between vesicoureteral reflux grade and bladder compliance. Material and Method: Videourodynamic traces of 53 children with primary vesicoureteral reflux investigated between January 2004 and January 2012 were reviewed. The detrusor pressures of the point when the reflux started were recorded. The detrusor pressures 10 cmH2O or less at that point was accepted as normal compliance (Group 1, the detrusor pressures more than10 cm H2O was accepted as hipocompliance (Group 2. The reflux grades were divided into two grades, low-grade reflux (grades 1 and 2, high-grade reflux (grades 3, 4 and 5. Data were analyzed using the chi-square test. Results: Patients’ ages ranged between 5 and 11 years (mean 7.09±1.81 years. Of the 53 patients, 29 (54.7% had normal compliance (Group 1, 24 (45.3% had hipocompliance (Group 2. Twenty-four (82.8% patients in-group 1 had a low-grade reflux, 5 (17.2% patients had a high-grade reflux. In group 2, 8 (33.3% patients had a low-grade reflux, 16 (66.7% patients had a high-grade reflux. The detected high-grade reflux in-group 2 was significantly higher than in-group 1 (p<0.001. Discussion: The physicians should be considering the bladder compliance at the point when the reflux started in primary vesicoureteral reflux cases. The bladder hipocompliance may play a secondary role in reflux grade.

    There is a known association between nonneurogenic lower urinary tract conditions and vesicoureteral reflux. Whether reflux is secondary to the lower urinary tract condition or coincidental is controversial. We determined the rate of reflux resolution in patients with lower urinary tract dysfunction using targeted treatment for the underlying condition. Patients diagnosed and treated for a lower urinary tract condition who had concomitant vesicoureteral reflux at or near the time of diagnosis were included. Patients underwent targeted treatment and antibiotic prophylaxis, and reflux was monitored with voiding cystourethrography or videourodynamics. Vesicoureteral reflux was identified in 58 ureters in 36 females and 5 males with a mean age of 6.2 years. After a mean of 3.1 years of treatment reflux resolved with targeted treatment in 26 of 58 ureters (45%). All of these patients had a history of urinary tract infections before starting targeted treatment. Resolution rates of vesicoureteral reflux were similar for all reflux grades. Resolution or significant improvement of reflux was greater in the ureters of patients with dysfunctional voiding (70%) compared to those with idiopathic detrusor overactivity disorder (38%) or detrusor underutilization (40%). Vesicoureteral reflux associated with lower urinary tract conditions resolved with targeted treatment and antibiotic prophylaxis in 45% of ureters. Unlike the resolution rates reported in patients with reflux without a coexisting lower urinary tract condition, we found that there were no differences in resolution rates among grades I to V reflux in patients with lower urinary tract conditions. Patients with dysfunctional voiding had the most improvement and greatest resolution of reflux. Additionally grade V reflux resolved in some patients.

    Full Text Available Evaluation of the relative merits of medical versus surgical management of vesicoureteral reflux (VUR has been limited by the few prospective studies comparing these strategies. Among those trials that have been reported, the only consistent positive finding has been that incidence of febrile UTI is lower among children undergoing surgical treatment in comparison with medical treatment. Studies have not found significant differences in overall incidence of UTI, or in rates of new renal scarring or progression of existing scarring. It is likely that there is a subset of children with VUR who do benefit from aggressive treatment of their VUR, but we are not yet able to fully determine which children these are. It is hoped that future research will further clarify which treatments are useful in which children.

    Full Text Available Gastroesophageal reflux disease (GERD is a common chronic disease of the gastrointestinal tract that occurs in 3.1% of the Chinese population [1]. Heartburn, acid regurgitation and epigastric pain are typical clinical symptoms of GERD. These symptoms can affect patients' work productivity, sleep, diet and daily activities, thus resulting in a reduced quality of life (QOL [2]. Although patient QOL is increasingly being considered as a medical outcome index in the evaluation of the impact of GERD symptoms on patients' health status, measuring patient QOL in clinical trials can be challenging due to the lack of a standard assessment tool. Therefore, we aim to review the commonly used generic, disease-specific and hybrid QOL questionnaires to evaluate patients with GERD to provide a reference for clinical nursing work.

    Sweden has a population of a little more than 9.4 million. The rapid growth of immigration in Sweden has resulted in an increased number of minority ethnic patients and minority ethnic nurses in the Swedish healthcare system. This also applies to paediatric care. The purpose of this study was to explore how parents with ethnic Swedish backgrounds experience minority ethnic nurses' cultural competence and the care the nurses provide in a Swedish paediatric care context. This exploratory qualitative study is of 14 parents with an ethnic Swedish background whose child was in a ward at a children's hospital in Stockholm County Council. Data were collected using semi-structured interviews to identify parents' perceptions and experiences of minority ethnic nurses' cultural competence. The interviews were analysed by qualitative content analysis. The analyses of the interviews led to four main categories: influence of nurses' ethnicity; significance of cross-cultural communication; cross-cultural skills; and the importance of nursing education. Nurses' ethnicity did not have much impact on parents' satisfaction with their child's care. The parents attached importance to nurses' language skills and to their adaptation and awareness of Swedish culture. They also attached weight to nurses' professional knowledge and personal attributes. The role of nursing education to increase nurses' cultural awareness was highlighted too. © 2013 Nordic College of Caring Science.

    BACKGROUND: Patient satisfaction is increasingly regarded as an important aspect of measuring treatment success in individuals with gastroesophageal reflux disease (GERD). OBJECTIVE: To review how satisfied patients with GERD are with their medication, and to analyze the usefulness of patient satisfaction as a clinical end point by comparing it with symptom improvement. METHODS: Systematic searches of the PubMed and EMBASE databases identified clinical trials and patient surveys published between 1966 and 2009. RESULTS: Twelve trials reported that 56% to 100% of patients were ‘satisfied’ or ‘very satisfied’ with proton pump inhibitor (PPI) treatment for GERD. Patient satisfaction levels were higher for PPIs than other GERD medications in two trials. The sample-size-weighted average proportion of patients ‘satisfied’ with their PPI after four weeks of treatment in trials was 93% (95% CI 87% to 99%), with 73% (95% CI 62% to 83%) being ‘very satisfied’. In four surveys, the average proportion of patients ‘satisfied’ with their PPI treatment was 82% (95% CI 73% to 90%) and 62% (95% CI 48% to 75%) were ‘very satisfied’. Seven trials found a positive association between patient satisfaction and symptom improvement, and two surveys between satisfaction and improved health-related quality of life. Three trials found that continuous treatment yielded higher rates of satisfaction than on-demand therapy. CONCLUSIONS: More than one-half of patients were satisfied with their PPI medication in trials, and more patients were satisfied with PPIs than other medication types. An association between patient satisfaction and symptom resolution was found, suggesting that patient satisfaction is a useful end point for evaluating GERD treatment success. PMID:22506259

    To date, most concepts on the frequency of gastro-oesophageal reflux episodes and the efficiency of the antireflux barrier have been based on inferences derived from measurement of oesophageal pH. The development of intraluminal impedance monitoring has highlighted the fact that pH monitoring does not detect all gastro-oesophageal reflux events when little or no acid is present in the refluxate, even if special pH tracing analysis criteria are used. In November 2002, a workshop took place at which 11 specialists in the field of gastro-oesophageal reflux disease discussed and criticised all currently available techniques for measurement of reflux. Here, a summary of their conclusions and recommendations of how to achieve the best results from the various techniques now available for reflux measurement is presented. PMID:15194656

    Since the development of ambulatory esophageal pH monitoring test to diagnose gastroesophageal reflux disease (GERD), several parameters have been introduced. The aim of this study was to assess whether using the symptom index (SI), symptom sensitivity index (SSI), and symptom association probability (SAP), in addition to the DeMeester score (DS), would be useful for interpreting the Bravo pH monitoring test. A retrospective study, which included 68 patients with reflux symptoms refractory to proton pump inhibitor (PPI) therapy who underwent a Bravo capsule pH test between October 2006 and May 2015, was carried out. Acid reflux parameters and symptom reflux association parameters were analyzed. The median percent time of total pHvariation in percent time of total pHpH test, diagnosis of GERD, including reflux hypersensitivity, can be improved by performing an analysis of the symptom-reflux association and of the day-to-day variation.

    One of the things that makes life both very frustrating and also very interesting is that accomplishing one objective frequently means backpedaling on another. Since economics is the study of tradeoffs, this means that there is generally plenty for economists to do. William Nordhaus is one of the best economists anywhere, and he has written a wonderful book about the tradeoffs faced by one country--Sweden--if and as it acts on a decision its citizens made in 1980 to phase out the use of nuclear power there. The author adds that this decision has been reaffirmed by the Swedish Parliament on several occasions since the 1980 referendum, though with some elusive qualifications. What will be both the environmental and also the economic implications of a Swedish phaseout of the use of nuclear power to generate electricity there. These are the two issues Nordhaus addresses in this book

    The environmental monitoring programme for the nuclear facilities has shown that the radioactive discharges increase the concentrations of some radionuclides in the local marine environment around the Swedish nuclear facilities. Samples from the terrestrial environment rarely show increased radionuclide concentrations. From a radiological point of view the most important nuclide in the environmental samples usually is CS-137. However, the largest part of the present concentrations of Cs-137 in the Swedish environment originate from the Chernobyl accident. The concentrations of radionuclides that can be found in biota around the nuclear facilities are much lower than the concentration levels that are known to give acute damage to organisms. The total radiation doses from the discharges of radionuclides are small. (au)

    2017-06-01

    We present demographic differences across the gastro-oesophageal reflux disease (GORD) spectrum in a UK District General Hospital. Data were prospectively collected over 37 years. At endoscopy patients were categorized as: erosive oesophagitis (EO), Barrett's oesophagus (BO) or nonerosive reflux disease (NER). Analysis 1: comparison of EO, BO and NER 1977-2001 when the database for GORD without BO closed. Analysis 2: demographic differences in oesophageal adenocarcinoma (OAC) in total BO population diagnosed 1977-2011. GORD 1977-2001 (n=11 944): sex, male predominance in EO and BO but not NER; male : female ratios, 1.81, 1.65, 0.87, respectively (P<0.0001); mean age at presentation, EO 54 years, BO 62 years, NER 50 years; women were older than men by 10, 7 and 6 years, respectively.BO 1977-2011: prevalent OAC, 87/1468 (6%); male : female ratio, 4.1 (P<0.0001); incident OAC, 54/1381 (3.9%); male : female ratio, 3.5 (P<0.0001). Among all BO, more men developed OAC (3 vs. 0.9%). Within each sex, proportion of OAC higher among men (4.9 vs. 2.3%); at OAC diagnosis women were slightly but not significantly older (69.9 vs. 72.3 years, P=0.322). Two views may explain our findings. First, women have either milder reflux, or reduced mucosal sensitivity hence reflux remains silent for longer. Alternatively, women genuinely develop reflux later, that is, are more protected and for longer from developing GORD and its complications. Early evidence is emerging that female sex hormones may indeed have a protective role in GORD during the reproductive period. We suggest reflux and its consequences may be an example of 'protection' conferred on Eve.

  15. Prevalence of gastro-oesophageal reflux disease symptoms and reflux-associated respiratory symptoms in asthma

    2010-01-01

    Background Gastro-oesophageal reflux disease (GORD) symptoms are common in asthma and have been extensively studied, but less so in the Asian continent. Reflux-associated respiratory symptoms (RARS) have, in contrast, been little-studied globally. We report the prevalence of GORD symptoms and RARS in adult asthmatics, and their association with asthma severity and medication use. Methods A cross-sectional analytical study. A validated interviewer-administered GORD scale was used to assess frequency and severity of seven GORD symptoms. Subjects were consecutive asthmatics attending medical clinics. Controls were matched subjects without respiratory symptoms. Results The mean (SD) composite GORD symptom score of asthmatics was significantly higher than controls (21.8 (17.2) versus 12.0 (7.6); P < 0.001) as was frequency of each symptom and RARS. Prevalence of GORD symptoms in asthmatics was 59.4% (95% CI, 59.1%-59.6%) versus 28.5% in controls (95% CI, 29.0% - 29.4%). 36% of asthmatics experienced respiratory symptoms in association with both typical and atypical GORD symptoms, compared to 10% of controls (P < 0.001). An asthmatic had a 3.5 times higher risk of experiencing a GORD symptom after adjusting for confounders (OR 3.5; 95% CI 2.5-5.3). Severity of asthma had a strong dose-response relationship with GORD symptoms. Asthma medication use did not significantly influence the presence of GORD symptoms. Conclusions GORD symptoms and RARS were more prevalent in a cohort of Sri Lankan adult asthmatics compared to non-asthmatics. Increased prevalence of RARS is associated with both typical and atypical symptoms of GORD. Asthma disease and its severity, but not asthma medication, appear to influence presence of GORD symptoms.

    In a follow-up after fundoplication, 61 patients underwent a double contrast examination of the stomach and a radiologic examination to detect any gastro-oesophageal reflux. The radiologic findings were compared with pH reflux test and symptoms. Gastro-oesophageal reflux was found in 7 patients at radiologic examination. None of these patients had an adequate fundoplication at a double contrast examination of the stomach and all had symptoms indicating reflux. Recurrence of gastro-oesophageal reflux may be shown at the radiologic examination and predicted by the morphologic appearances at the double contrast examination. (orig.)

    The influence of Cisapride on food-stimulated gastro-oesophageal reflux meachanisms was studied in a double-blind cross-over investigation in 24 consecutive patients selected by endoscopy, 12 with microscopical evidence of gastro-oesophageal reflux and 12 with additional macroscopic oesoghagitis. 63% had food-stimulated gastro-oesophageal reflux, and Cisapride significantly reduced the tendency to gastro-oesophageal reflux and mucosal contact time between gastric content and the oesophageal mucosa in 73% of these patients. It is concluded that Cisapride could be valuable in the treatment of gastro-oesophageal reflux. (orig.) [de

    This paper examines the development of taxation in Sweden from 1862 to 2013. The examination covers six key aspects of the Swedish tax system: the taxation of labor income, capital income, consumption, inheritance and gift, wealth and real estate. The importance of these taxes varied greatly over time and Sweden increasingly relied on broad-based taxes (such as income taxes and general consumption taxes) and taxes that were less visible to the public (such as payroll taxes and social security...

    Relative clauses are considered strong islands for extraction across languages. Swedish comprises a well-known exception, allegedly allowing extraction from relative clauses (RCE), raising the possibility that island constraints may be subject to “deep variation” between languages. One alternative is that such exceptions are only illusory and represent “surface variation” attributable to independently motivated syntactic properties. Yet, to date, no surface account has proven tenable for Swed...

    This paper investigates the entrepreneurial spirit in Swedish listed family firms. We associate family firms with entrepreneurship in the sense that there is an identifiable person that takes the uninsurable risk in the sense of Knight. This paper analysis two questions: Do entrepreneurial family firms have a higher rate of growth and do they invest in a more profit maximizing fashion than other listed firms? The analysis shows that entrepreneurial family firms in general are smaller in terms...

    The Organization of Estonian energetic economy is aimed at cutting the usage of oil, gas and coal and increasing the local resources firewood, oil-shale and peat for fuel. The resources of low-valued firewood-brushwood, fallen deadwood etc. are available during the following 10-15 years, but in the future the cultivation of energy forest (willow) plantations will be actual. During the last 20 years the Swedish scientists have been extensively studying the willow forest selection, cultivation and use in energetics and waste water purification systems. A Swedish-Estonian energy forest research project was started in 1993 between the Swedish Agricultural University on one hand and Toravere Observatory, Institute of Zoology and Botany, Estonian Academy of Sciences and Estonian Potato Processing Association on the other hand. In spring 5 willow plantations were established with the help of Swedish colleagues and obtained from Sweden 36000 willow cuttings. The aim of the project: a) To study experimentally and by means of mathematical modelling the biogeophysical aspects of growth and productivity of willow plantations in Sweden and Estonian climatological conditions. b) To study the possibility of using the willow plantations in waste waters purification. c) To study the economical efficiency of energy forest as an energy resource under the economic and environmental conditions of Estonia. d) To study the economic efficiency of willow plantations as a raw material for the basket industry in Estonia. e) To select the most productive and least vulnerable willow clones for practical application in energy plantations. During 1993 in all five plantations detailed analysis of soil properties has been carried out. In the plantation at Toravere Observatory phytometrical measurements were carried out - the growth of plant biomass leaf and stem area, vertical distribution of dry matter content, biomass and phyto area separately for leaves and stems has been performed.

    We compared the ability of laparoscopic antireflux surgery (LARS) and esomeprazole to control esophageal acid exposure, over a 5-year period, in patients with chronic gastroesophageal reflux disease (GERD). We also studied whether intraesophageal and intragastric pH parameters off and on therapy were associated with long-term outcomes. We analyzed data from a prospective, randomized, open-label trial comparing the efficacy and safety of LARS vs esomeprazole (20 or 40 mg/d) over 5 years in patients with chronic GERD. Ambulatory intraesophageal and intragastric 24-hour pH monitoring data were compared between groups before LARS or the start of esomeprazole treatment, and 6 months and 5 years afterward. A secondary aim was to evaluate the association between baseline and 6-month pH parameters and esomeprazole dose escalation, reappearance of GERD symptoms, and treatment failure over 5 years in patients receiving LARS or esomeprazole. In the LARS group (n = 116), the median 24-hour esophageal acid exposure was 8.6% at baseline and 0.7% after 6 months and 5 years (P acid exposure was 8.8% at baseline, 2.1% after 6 months, and 1.9% after 5 years (P acidity was stable in both groups. Patients who required a dose increase to 40 mg/d had more severe supine reflux at baseline, and decreased esophageal acid exposure (P acidity after dose escalation. Esophageal and intragastric pH parameters, off and on therapy, did not predict long-term symptom breakthrough. In a prospective study of patients with chronic GERD, esophageal acid reflux was reduced greatly by LARS or esomeprazole therapy. However, patients receiving LARS had significantly greater reductions in 24-hour esophageal acid exposure after 6 months and 5 years. Esophageal and gastric pH, off and on therapy, did not predict long-term outcomes of patients. Abnormal supine acid exposure predicted esomeprazole dose escalation.

    Global health education is increasingly acknowledged as an opportunity for medical schools to prepare future practitioners for the broad health challenges of our time. The purpose of this study was to describe the evolution of global health education in Swedish medical schools and to assess students' perceived needs for such education. Data on global health education were collected from all medical faculties in Sweden for the years 2000-2013. In addition, 76% (439/577) of all Swedish medical students in their final semester answered a structured questionnaire. Global health education is offered at four of Sweden's seven medical schools, and most medical students have had no global health education. Medical students in their final semester consider themselves to lack knowledge and skills in areas such as the global burden of disease (51%), social determinants of health (52%), culture and health (60%), climate and health (62%), health promotion and disease prevention (66%), strategies for equal access to health care (69%) and global health care systems (72%). A significant association was found between self-assessed competence and the amount of global health education received (pcurriculum. Most Swedish medical students have had no global health education as part of their medical school curriculum. Expanded education in global health is sought after by medical students and could strengthen the professional development of future medical doctors in a wide range of topics important for practitioners in the global world of the twenty-first century. © 2015 the Nordic Societies of Public Health.

    Full Text Available Introduction: Gastroesophageal reflux is a common gastrointestinal disorder among infants, which can cause complications, such as esophagitis and Barrett's esophagus if its diagnosis and treatment are delayed. On the other hand, similarity of Gastro esophageal Reflux symptoms with symptoms of other childhood diseases makes its diagnosis and treatment difficult. So a proper tool for early screening and diagnostic test is essential. Methods: This study was conducted on 221 infants(2 to 12 months with initial symptoms of gastro esophageal reflux(frequent vomiting, restlessness after feeding, no weight gain, coughing repeatedly and refusing to eat that referred to pediatric Clinic of Rajai Hospital in Tonekabon. Data was collected with demographic and infant gastro esophageal reflux questionnaire by use of the information in records and interview with parents. Then the samples were examined via sonography for gastroesophagial reflux. Results: After initial screening based on infants gastro esophageal reflux tool, gastro esophageal reflux by ultrasound was positive in 63/3% of infants. The mean esophageal diameter was (20/73±2/54mm in infants with gastro esophageal reflux and (23/71±2/35mm in infants without gastro esophageal reflux. Conclusion: Due to the similarity of gastro esophageal Reflux symptoms with clinical symptoms of other childhood diseases, use of an initial screening measurement for early assessment of gastro esophageal reflux in infants is necessary. Moreover, appropriate, available and low costs diagnostic method with little complication seems essential such as ultrasonography for confirm diagnosis and early treatment.

    The study and clinical assessment of enterogastric bile reflux has been restricted for want of a simple non-invasive test for its detection and quantification. This paper describes such a test in which biliary excretion scintigraphy has been combined with a milk meal provocation. Two of 10 healthy volunteers studied showed probable reflux of approximately 5 per cent of total initial abdominal field activity. Among 73 patients studied, 37 patients showed definite reflux of up to 47 per cent. Reflux occurred in 19 of 22 post-gastric surgery patients and in 7 of 22 patients with peptic ulcer disease, gastritis or gastro-oesophageal reflux. None of 7 patients with 'non-specific' abdominal pain showed any reflux, but 11 of 22 patients with gallstone disease or previous cholecystectomy showed reflux of up to 35 per cent, including 9 of 11 patients with loss of gallbladder reservoir function.

    The hypothesis that GER can trigger or exacerbate asthma is supported by several clinical trials that have shown amelioration in asthma symptoms and/or an improvement in pulmonary function after antireflux therapy. To investigate the prevalence of GER in patients with difficult to control asthma and to determine the effect of omeprazole on asthma symptoms, reflux symptoms, pulmonary function and on the requirement of asthma medications. Patients with difficult to control asthma were recruited into the study. All patients underwent esophageal manometry and 24 hour esophageal pH monitoring. Pulmonary function tests were done before and after treatment. The severity of asthma and reflux was assessed by a 1 week pulmonary symptom score(PSS) and reflux symptom score(RSS) respectively before and after treatment. Those who had an abnormal pH study (pH 5% of the time) underwent anti-GER treatment with lifestyle changes, and a proton pump inhibitor (omeprazole 40 mg, bid) for 3 months. Asthma medications were added or deleted based on severity of asthma. Out of 250 asthmatic patients screened, forty patients fulfilled the inclusion criteria. Twenty eight of 40 patients(70%) were diagnosed to have GERD. Of the patients 28 with GER, 8 patients(28.5%) had no reflux symptoms. On 24 hr pH metry, the percentage time pH reflux symptom score(RSS) improved from 22.39 ± 14.99 to 1.04 ± 1.07, pulmonary symptom score(PSS) improved from 27.14 ± 7.49 to 13.82 ± 4.21 and night time asthma symptom score(NASS) improved from 6.71 ± 1.80 to 3.04 ± 1.23 (p-value <0.0001). After treatment, FEV1 and PEFR increased from 1.38 ± 0.57 and 4.14 ± 1.97 to 1.47 ± 0.54 and 5.56 ± 1.72, respectively (p-value 0.00114). PPI therapy improves nocturnal asthma symptoms, daytime asthma symptoms, pulmonary function and decreases requirement of asthma medications in these patients.

    In the Swedish nuclear power industry staff, very few newly employed have a deep education in reactor technology. To remedy this, a joint education company, Nuclear Training and Safety Center (KSU), has been formed. To ensure that nuclear competence will be available also in a long-term perspective, the Swedish nuclear power industry and the Swedish Nuclear Power Inspectorate (SKI) have formed a joint center for support of universities, the Swedish Nuclear Technology Center (SKC). The activities of these organisations, their links to universities, and their impact on the competence development for the nuclear power industry will be outlined. (author)
