A prospective 1-year follow-up study in patients with functional or organic dyspepsia: changes in gastrointestinal symptoms, mental distress and fear of serious illness.

BACKGROUND: Psychosocial factors are common among patients with functional gastrointestinal disorders (FGIDs). Whether they affect the course of the disease remains unresolved. AIM: To evaluate whether reassuring investigations of primary care patients with functional dyspepsia (FD) and organic dyspepsia (OD) influence gastrointestinal (GI) symptoms and psychological factors, and to assess whether these changes are correlated. METHODS: Four hundred consecutive patients with dyspepsia were referred for thorough examinations. Patients completed questionnaires screening symptoms at baseline and on 1-year follow-up. RESULTS: At baseline, there was no difference in GI symptoms, prevalence of mental distress or fear of serious illness between patients with FD or OD. On follow-up, the patients with FD had more GI symptoms, but there was no difference in mental distress or fear of serious illness. Relevant GI symptom reduction related to alleviation of mental distress (53.4% vs. 20.5%, P < 0.001) and fear of serious illness (56.5% vs. 23.7%, P = 0.002), but reached statistical significance only in patients with OD. CONCLUSIONS: Gastrointestinal symptoms in FD patients are long lasting compared with those with organic diseases. Reassuring investigations could lower mental distress and fear of serious illness in these patients. Psychological factor change correlates with the change in GI symptom severity and is not specific to FGIDs.

Mental distress in patients with functional or organic dyspepsia: a comparative study with a sample of the general population.

BACKGROUND: It has been argued that patients with functional gastrointestinal disorders have mental disorders more often than healthy controls and patients with organic disease. Most studies surveying psychological factors at the population level have relied on symptom questionnaires to diagnose functional dyspepsia. However, the symptom patterns alone are unable to adequately discriminate organic from functional dyspepsia. AIM: To evaluate the frequency of mental distress in primary care patients with organic or functional dyspepsia and compare the findings with a sample of the Finnish general population. METHODS: Four-hundred consecutive, unselected dyspeptic patients were referred for upper gastrointestinal endoscopy and other diagnostic examinations. All patients compiled a self-administered questionnaire including the 12-item General Health Questionnaire to detect cases of recent mental disorders. RESULTS: The prevalence of mental distress among patients with functional and organic dyspepsia was 38 and 36.4% respectively. The sex- and age-adjusted risk of having mental distress was nearly fourfold higher among patients with dyspepsia than in the general population. CONCLUSION: Mental distress is common among patients with functional or organic dyspepsia. Nevertheless, there is no difference between patients with functional or organic dyspepsia in the prevalence or risk of mental distress.

High success rate and low incidence of headache and neurological symptoms with two spinal needle designs in children.

BACKGROUND: In children, only a few trials have evaluated the use of spinal needles with special tip designs. In this study, we compared the success rate and incidence of post-dural puncture complaints of two small-gauge spinal needle designs used in children undergoing spinal anaesthesia (SA). METHODS: Three hundred and three children aged 9 months to 17 years presenting for subumbilical surgery were randomly assigned to have a 26G Atraucan (n = 156) or 27G Whitacre (n = 147) spinal needle for SA. The number of attempts to obtain successful cerebrospinal fluid (CSF) return and the success rate of SA were recorded. The first week of recovery was recorded by a diary. RESULTS: Both groups had a similar one-attempt success rate: 80% in the Atraucan group and 81% in the Whitacre group. Failure to obtain CSF occurred in one patient in the Atraucan group and in two patients in the Whitacre group. Paraesthesia was observed more commonly in the Whitacre group (10%) than in the Atraucan group (2%) (P = 0.004). The success rate of SA was 96%, with no differences between the two needles; one child was given general anaesthesia and 11 children (3%) a single dose of supplemental analgesia for the skin incision. Forty-one children (15%) developed a headache, 13 of which were classified as post-dural puncture headache (PDPH), seven cases (5%) in the Atraucan group and six (4%) in the Whitacre group; none of the children required a blood patch. Fifteen children (10%) in the Atraucan group and nine (7%) in the Whitacre group developed low back pain. Two children (1%) in the Atraucan group and four (3%) in the Whitacre group developed transient neurological symptoms (TNSs). CONCLUSION: Both needles were associated with a high success rate and a low incidence of complaints.

The profile of leg symptoms, clinical disability and reflux in legs with previously operated varicose disease.

PURPOSE: It is difficult to assess the severity and location of venous insufficiency in legs with recurrent varicose disease. This present purpose was to evaluate the distribution of reflux and the diagnostic role of current classifications in a consecutive series of legs with previously operated varicose disease. METHODS: A total of 90 legs in a cohort of 66 patients were included. The examination comprised CEAP clinical class, clinical disability score (CDS) and leg symptoms. Colour-flow duplex imaging (CFDI) was used to observe reflux in deep and superficial veins. Details of prior surgery were assessed. RESULTS: The site of superficial reflux was at the groin in 58% (recurrent or residive vein trunk or unoperated great saphenous vein), and the rate in the popliteal fossa was 11% (unoperated short saphenous vein). In 58% of the legs presenting superficial reflux at groin level, previous surgery at the saphenofemoral junction was noted. A sensation of pain was observed in 74% of the legs, sensation of oedema in 64%, itching in 26 %, and night cramps in 8%, respectively. Only itching was significantly infrequent in uncomplicated (CEAP C 2-3) legs, and in legs with local reflux was restricted to vein tributaries. Higher CDS (classes 2-3) were significantly more frequent among complicated legs (CEAP clinical class C2-3: 22% versus CEAP clinical class C4-6: 77%; p < 0.005). A similar situation was noted when legs with only local reflux were compared to those with more severe reflux (local reflux: 7% versus severe reflux: 48%; p < 0.005). CONCLUSIONS: Superficial reflux is frequently detected at groin level despite prior surgery. Unstructured evaluation of leg symptoms is not beneficial. Clinical disability scores associate well with the severity of the venous disease.

Long-term outcome after internal sphincter myectomy for internal sphincter achalasia.

Anal internal sphincter achalasia is a rare cause of refractory constipation. It is usually treated by internal sphincter myectomy (ISM). The aim of this study was to evaluate the long-term outcome of patients who had undergone ISM for internal sphincter achalasia. Bowel habits, fecal continence, and quality of life were evaluated using a questionnaire. Fecal continence was quantitatively assessed by a score described by Holschneider. A questionnaire was sent to 13 patients (11 male, two female) operated on by ISM for intractable constipation caused by internal sphincter achalasia between 1983 and 1993. Ten patients responded and were included in the study. At the time of the study, three of the 10 patients required oral medication for constipation and had one to three bowel movements per week. One of the 10 patients had three to five bowel movements per day, and the others had one to two bowel movements per day. Four patients had normal and six patients had good continence scores. Four of the patients reported mild social problems, and one had problems associated with sports. Refractory constipation in the majority of patients with internal sphincter achalasia can be treated by ISM. However, in the long term, a significant number of patients suffer from soiling-related social problems.

Primary Helicobacter pylori resistance to metronidazole and clarithromycin in the Finnish population.

AIM: To systematically determine Helicobacter pylori primary antimicrobial resistance in Finland and the associated demographic and clinical features. METHODS: A total of 342 adult patients referred for gastroscopy at 23 centres in different parts of Finland and positive for the rapid biopsy urease test were recruited. Clinical and demographic data were collected via a structured questionnaire. Patients with positive H. pylori culture and successful antibiotic sensitivity determination by the E-test method (n = 292) were included in the present analysis. RESULTS: The study population consisted of 134 men and 158 women, mean age 56 years (95% CI, 55-58 years). Resistance to metronidazole was 38% (110 of 292) and to clarithromycin 2% (seven of 292). Resistance to metronidazole was higher in women than in men (48% vs. 25%, P < 0.001). Previous use of antibiotics for gynaecological infections predicted metronidazole resistance (P = 0.01), and previous use of antibiotics for respiratory (P = 0.02) and dental infections (P = 0.02) the clarithromycin resistance. We observed no major geographical variations in metronidazole resistance. CONCLUSIONS: The primary metronidazole resistance of H. pylori was 38% and was common in women previously treated for gynaecological infections. Primary clarithromycin resistance was uncommon (2%) and may associate with previous dental and respiratory infections.

Glasgow Aneurysm Score as a predictor of immediate outcome after surgery for ruptured abdominal aortic aneurysm.

BACKGROUND: The aim of the study was to assess the value of the Glasgow Aneurysm Score in predicting postoperative death after repair of a ruptured abdominal aortic aneurysm (AAA). METHODS: Between 1991 and 1999, 836 patients underwent surgery for ruptured AAA. Their operative risk at presentation was evaluated retrospectively using the Glasgow Aneurysm Score, based on data from the nationwide Finnvasc registry. RESULTS: The operative mortality rate was 47.2 per cent (395 of 836); 164 patients (19.6 per cent) had cardiac complications and 164 (19.6 per cent) required intensive care treatment for more than 5 days. Predictors of postoperative death in univariate analysis were: coronary artery disease (P = 0.005), preoperative shock (P < 0.001), age (P < 0.001), and the Glasgow Aneurysm Score (P < 0.001). In multivariate analysis the predictors were: preoperative shock (odds ratio (OR) 2.13 (95 per cent confidence interval (c.i.) 1.45 to 3.11); P < 0.001) and the Glasgow Aneurysm Score (for an increase of ten units: OR 1.81 (95 per cent c.i. 1.54 to 2.12); P < 0.001). Receiver-operator characteristic (ROC) curves showed that the best cut-off value of the Glasgow Aneurysm Score in predicting postoperative death was 84 (area under the curve 0.75 (95 per cent c.i. 0.72 to 0.78), standard error 0.17; P < 0.001). The operative mortality rate was 28.2 per cent (114 of 404) in patients with a Glasgow Aneurysm Score of 84 or less, compared with 65.0 per cent (281 of 432) in those with a score greater than 84 (P < 0.001). CONCLUSION: The Glasgow Aneurysm Score predicted postoperative death after repair of ruptured AAA in this series.

Prognostic significance of antrum-predominant gastritis in functional dyspepsia.

BACKGROUND: The role of Helicobacter pylori infection in functional dyspepsia is still controversial, and subgroups of patients with functional dyspepsia who may benefit from H. pylori eradication should be identified. Patients with functional dyspepsia and antrum-predominant H. pylori-positive chronic gastritis, it has been argued, have fewer symptoms after eradication therapy. In the present study, we analysed the clinical significance of antrum-predominant gastritis on the long-term prognosis of functional dyspepsia. METHODS: Consecutive unselected dyspeptic patients were investigated in primary care and the patients with functional dyspepsia were enrolled in this long-term follow-up study. Altogether 182 patients were recruited: 65 with normal histology of the stomach, 36 with antrum-predominant gastritis, 21 with corpus-predominant gastritis and 60 with pangastritis. Patients' medical histories were reviewed after 6 to 7 years, with total number and outcome of repeated investigations analysed. At the end of follow-up, all patients were invited for voluntary gastroscopy. RESULTS: At the end of follow-up, the proportion of asymptomatic patients ranged from 21% (normal histology) to 26% (antrum-predominant gastritis). No statistically significant differences between groups appeared in regard to re-visits or to proportion of patients examined by sigmoideo- or colonoscopy during follow-up. Patients with antrum-predominant gastritis less often underwent upper endoscopy. Peptic ulcer was more frequent (P = 0.05) in patients with antrum gastritis than in other groups, but no other differences existed among any organic gastrointestinal findings. No significant differences between subgroups appeared among the 30% of patients using drugs for upper abdominal complaints during the previous year. CONCLUSIONS: Functional dyspepsia has an excellent long-term prognosis. Antrum-predominant gastritis in functional dyspepsia seems to carry an increased risk for peptic ulcer, and for this group in particular, H. pylori eradication should be considered. This finding requires confirmation in future studies performed in primary care.

What is the long-term outcome of the different subgroups of functional dyspepsia?

BACKGROUND: Functional dyspepsia is often a long-lasting disorder that accounts for substantial healthcare costs. It has been classified into subgroups assuming that it can guide management of dyspepsia. AIM: To evaluate the clinical significance of subgrouping functional dyspepsia in a long-term perspective study. METHODS: Consecutive patients with dyspepsia identified by general practitioners were investigated. Those patients with functional dyspepsia (n=201) were enrolled in this study. Initially, patients were divided into five subgroups (ulcer-like, dysmotility-like, reflux-like, unspecified, and irritable bowel syndrome-like). Patients' medical histories were reviewed after 6-7 years, and the number and outcome of repeated investigations were analysed. At the end of follow-up, patients filled in a questionnaire similar to that at baseline, and were invited for gastroscopy. RESULTS: Only 2% of patients developed peptic ulcer during follow-up, none of them were in the ulcer-like subgroup. When referrals to hospital and examinations during follow-up were registered, no statistically significant differences existed between subgroups. Patients with reflux-like dyspepsia made fewer revisits than others (P=0.02), but had used antidyspepsia drugs during the previous year more often (P=0.036). Stability of the subgroups over time was poor. CONCLUSIONS: Functional dyspepsia is a long-lasting disorder with a very good prognosis. Subgroups of functional dyspepsia play only a minor role in prediction of the long-term outcome, and their usefulness in clinical practice is also hampered by subgroup instability over time.

Glasgow Aneurysm Score in patients undergoing elective open repair of abdominal aortic aneurysm: a Finnvasc study.

OBJECTIVE: To use Finnvasc to determine whether the Glasgow Aneurysm Score predicts postoperative outcome after open repair of abdominal aortic aneurysm (AAA). DESIGN: Retrospective study. MATERIAL AND METHODS: The operative risk of 1911 patients undergoing open repair of AAA was retrospectively graded according to the Glasgow Aneurysm Score. RESULTS: At 30 days 100 (5%) patients had died and 21% had developed severe postoperative complications. Receiver operating characteristics (ROCs) curve analysis showed that the Glasgow Aneurysm Score was predictive of postoperative mortality (area under the curve (AUC): 0.668, p<0.0001), severe complications (AUC: 0.654, p<0.0001), cardiac complications (AUC: 0.689, p<0.0001) and intensive care unit stay >5 days (AUC: 0.634, p<0.0001). Patients scoring >76 had significantly higher mortality (9% vs. 3%, p<0.0001), severe (31% vs. 15%, p<0.0001) and cardiac complications (12% vs. 4%, p<0.0001) and intensive care unit stay >5 days (12% vs. 6%, p<0.0001). CONCLUSIONS: The Glasgow Aneurysm Score is a rather good predictor of immediate postoperative mortality and morbidity after elective open repair of AAA.

Primary vascular access surgery in a well defined geographical region: long-term results of autogenous arteriovenous fistulas.

BACKGROUND AND AIMS: Autogenous fistula should be constructed in a minimum of 50% of all new ESRD patients scheduled for haemodialysis. The radio-cephalic fistula described by Brescia and colleagues in 1966 is considered to be the access of choice due to its good patency and low complication rate. The aim of this study was to evaluate the outcome of primary access surgery in a well-defined geographical region in Finland. MATERIAL AND METHODS: All primary vascular access procedures between 1990-1999 were selected in the local vascular registry. Additional data was collected from patients' case records. Kaplan-Meier method was used to calculate fistula patency. Multivariate analysis of four variables (age, gender, diabetes mellitus, smoking) was done to determine their association with primary success RESULTS: 407 primary procedures were done during the 10-year period including 405 (99.5%) autogenous fistulas and two prosthetic grafts (0.5%). 230 (56.8%) fistulas were used for haemodialysis during the study. Cumulative primary functional patency at one year was 84.1%, at two years 75.2% and at five years 50.1%. An attempt to salvage a failing or failed fistula was done in only 15 (6.5%) cases with insignificant impact on outcome. None of the tested variables was associated with poor functional success. CONCLUSIONS: The strategy of using native radio-cephalic fistula as a first access site results in excellent early and long-term functional patency for ESRD patient.

Spousal resemblance for history of major depressive episode in the previous year.

BACKGROUND: There is discrepancy in findings on spousal concordance for major depression. Here we report the risk of depression and its determinants in spouses of persons with or without depression, taking into account several known risk factors for major depression. METHODS: A random sample of non-institutionalized Finnish individual aged 15-75 years was interviewed in the 1996 National Health Care Survey. The sample included 1708 male-female spouse pairs. Major depressive episode (MDE) during the last 12 months was assessed using the Short Form of the University of Michigan version of the Composite International Diagnostic Interview (the UM-CIDI Short Form). Risk factors were assessed in the same interview. RESULTS: Factors associating with MDE were spouse's MDE, own alcohol intoxication at least once a week and own chronic medical conditions. In addition, there was a strong association between female's current smoking and male's MDE, independently of other risk factors and spousal MDE. The association of MDE with spouses's MDE was not affected by taking into account other assessed risk factors (own or spouse's). CONCLUSIONS: The results indicate elevated spouse concordance for MDE independent of the risk factors assessed in the present study.

Ruptured abdominal aortic aneurysm in a well-defined geographic area.

OBJECTIVE: Despite an increasing number of elective operations on abdominal aortic aneurysms (AAAs), the age- and sex-standardized mortality rate of ruptured AAA (RAAA) continues to increase. In the Pirkanmaa region, population 440,000, all aortic surgery is performed at Tampere University Hospital (TAUH). Procedures have been collected into the vascular registry. The purpose of this study was (1) to establish the incidence, modes of treatment, and mortality of RAAA in a defined geographic area; (2) to evaluate the prerupture history to determine if there are any ways to prevent rupture; and to make a forecast about the increase of RAAAs in the next decades. METHODS: Population and outcome data in the Pirkanmaa region and information on all patients who died of RAAA during 1990-1997 were provided by Statistics Finland. All operated RAAAs that underwent procedures during 1990 to 1999 were identified from the local vascular registry. To make a forecast for the next decades, an incidence of RAAA was calculated separately for each age group in 5-year intervals. RESULTS: From 1990 to 1997, 221 patients presented with RAAA. The mean incidence was 6.3/100,000 inhabitants. The incidence in the population over 65 years was 35.5/100,000. The total RAAA mortality was 76.9%. A total of 139 patients reached TAUH and 111 underwent emergency surgery. The overall hospital mortality in TAUH was 63.3%. The calculated annual number of RAAA will increase 49.6% in the next 2 decades, and the overall incidence will increase from 6.3 to 8.9/100,000 inhabitants. According to the vascular registry, 166 patients were operated on for RAAA during 1990 to 1999 in TAUH. The 30-day mortality was 50.6%. A minority of the patients (n = 18, 10.8%) had a previously documented AAA. The median diameter at the time of rupture was 7 cm. Seven (5.0%) men and six (24.0%) women had a diameter of less than 5.5 cm. CONCLUSION: The incidence of RAAA in the Pirkanmaa region in 1990s was the Finnish average. In the next two decades, the number of individuals with RAAA will increase significantly. One quarter of women had a diameter of AAA at the time of rupture that was under the current threshold indicator for elective operation.

Long-term outcome of functional dyspepsia: effect of Helicobacter pylori infection. A 6- to 7-year follow-up study.

BACKGROUND: Dyspepsia accounts for substantial healthcare costs from medication use and expensive investigations, because most patients with upper abdominal complaints have functional dyspepsia. The role of Helicobacter pylori infection in functional dyspepsia is still controversial. The aim of this study was to investigate the effect of H. pylori infection on the natural history of functional dyspepsia and to evaluate the diagnostic yield of repeat examinations. METHODS: Unselected patients with dyspepsia in general practice were thoroughly investigated at baseline. Patients with functional dyspepsia were enrolled in this long-term follow-up study. The medical history of each patient was reviewed after 6 to 7 years, and the total number and outcome of repeat investigations recorded. Study patients filled in a dyspepsia questionnaire and were invited for voluntary gastroscopy at the end of follow-up. RESULTS: Of 205 eligible patients, 201 were finally enrolled in this study (118 H. pylori-positive and 83 H. pylori-negative). No malignancies explaining the patients' symptoms were found during follow-up. Only four cases of peptic ulcer disease were found in H. pylori-infected patients, i.e. an annual incidence of less than 1%. During the follow-up period, H. pylori-positive patients were investigated by endoscopy more often (47%) than H. pylori-negative patients (29%) (P = 0.011) with comparable findings in follow-up examinations. CONCLUSION: Functional dyspepsia is a long-lasting disorder with an excellent prognosis regardless of H. pylori infection.

No harm from five year ingestion of oats in coeliac disease.

BACKGROUND: Six to 12 months of ingestion of moderate amounts of oats does not have a harmful effect in adult patients with coeliac disease. As the safety of long term intake of oats in coeliac patients is not known, we continued our previous 6-12 month study for five years. AIM: To assess the safety of long term ingestion of oats in the diet of coeliac patients. PATIENTS: In our previous study, the effects of a gluten free diet and a gluten free diet including oats were compared in a randomised trial involving 92 adult patients with coeliac disease (45 in the oats group, 47 in the control group). After the initial phase of 6-12 months, patients in the oats group were allowed to eat oats freely in conjunction with an otherwise gluten free diet. After five years, 35 patients in the original oats group (23 still on an oats diet) and 28 in the control group on a conventional gluten free diet were examined. METHODS: Clinical and nutritional assessment, duodenal biopsies for conventional histopathology and histomorphometry, and measurement of antiendomysial, antireticulin, and antigliadin antibodies. RESULTS: There were no significant differences between controls and those patients consuming oats with respect to duodenal villous architecture, inflammatory cell infiltration of the duodenal mucosa, or antibody titres after five years of follow up. In both groups histological and histomorphometric indexes improved equally with time. CONCLUSIONS: This study provides the first evidence of the long term safety of oats as part of a coeliac diet in adult patients with coeliac disease. It also appears that the majority of coeliac patients prefer oats in their diet.

The fate of AAA patients referred electively to vascular surgical unit.

BACKGROUND: The ideal treatment of abdominal aortic aneurysms (AAA) is to operate aneurysms likely to rupture, without exposing other cases to major surgery. The purpose here was to analyse retrospectively the management of AAA in a well-defined geographical region in the 1990's. METHODS: 194 new vascular surgical outpatient consultations due to AAA were done to the regional vascular centre during the years 1990, 1992, 1994, 1996 and 1998. Data were collected from case records. Statistics Finland provided causes and dates of death. RESULTS: The mean observed annual AAA incidence was 9.0 per 100 000 inhabitants and it rose significantly (33.3%) during the study period. The duration of follow-up varied between 0 and 129 months. The 5/8-year cumulative mortality was 37.3/50.7%. The most common causes of death were AAA-related (31.7%), cardiac (29.1%) or malignancy (19.0%). Twenty-five patients with small AAA were referred to primary health care sector for further follow-up. There were no RAAA (ruptured AAA) deaths in this group. The cumulative 5/8-year mortality was 43.2/49.9%. One hundred patients underwent an elective aneurysm repair with in-hospital mortality of 7.0%. The cumulative 5/8-year mortality was 23.7/35.4%. Twelve patients refused elective treatment. The cumulative 5/8-year mortality was 45.1/ 63.4% and 5/7 deaths were due to RAAA. Twenty-three patients were unfit for elective repair. The cumulative 5/8-year mortality was 87.0%/100% and 5/20 deaths were caused by RAAA. The cumulative 5/8-year RAAA-rate in the patients with AAA more than 5.0 cm in diameter and outside elective aneurysm-repair (n = 23) was 51.9%/100.0%. CONCLUSION: The observed incidence of AAA increased during the 1990's. Half of the patients underwent an elective procedure. Patients unfit for surgery died mainly for other reasons than RAAA. Most patients with AAA over 5.5 cm not subjected to elective procedure, died of rupture.

Regular-dose versus high-dose omeprazole in peptic ulcer bleeding: a prospective randomized double-blind study.

BACKGROUND: It has been suggested that profound acid inhibition along with endoscopic therapy might prevent rebleeding and reduce mortality in patients with peptic ulcer bleeding. The aim of the study was to test the possible equivalence of a high dose and the regular dose of omeprazole in peptic ulcer bleeding. METHODS: We performed a prospective randomized double-blind study involving 142 patients with acute peptic ulcer bleeding (Forrest classification I-II: spurting or oozing bleeding, non-bleeding visible vessel, clot and black base). One-hundred-and-two (71.8%) patients received endoscopic treatment (adrenaline injection and/or heater probe) in pre-entry. Patients were randomly assigned to receive the regular dose of omeprazole intravenously (20 mg once a day for 3 days, i.e. 60 mg/72 h) or a high dose of omeprazole (80 mg bolus + 8 mg/h for 3 days, i.e. 652 mg/72 h). Rebleeding, surgery and death were the outcome measures. RESULTS: Six (8.2%) of the 73 patients receiving the regular dose of omeprazole and 8 (11.6%) of the 69 patients receiving the high dose of omeprazole rebled (P = 0.002 for equivalence, equivalence limit 0.15). Three (4.1%) of the former patients and 5 (7.2%) of the latter group underwent surgery. Four (5.5%) patients in the regular-dose and 2 (2.9%) in the high-dose group died within 30 days. CONCLUSION: Under the defined tolerance limits, the regular dose of omeprazole is as successful as a high dose in preventing peptic ulcer rebleeding.
