Role of pinaverium bromide in south Indian patients with irritable bowel syndrome.

The effect of pinaverium bromide in controlling gastrointestinal symptoms in 61 patients with irritable bowel syndrome was studied, as an open trial. Individually, there was significant relief in abdominal discomfort/pain as well as in bowel symptoms in most of the patients. Abdominal pain was reduced in 49%, stool consistency improved in 74%, straining and urgency decreased in 71% and mucus decreased in 64%. Tolerance to the drug administered was good and side-effects reported were few.

The effects of chronic ill health and treatment with sulphasalazine on fertility amongst men and women with inflammatory bowel disease in Leicestershire.

The aims of the study were to ascertain whether patients have similar a fertility rate to the background population in Leicestershire and whether they have a similar rate of congenital malformations compared to the background population in Leicestershire. Over 1400 patients were invided to participate with an overall response rate of 81% after three successive mailings. The response rate was similar for both sexes and between the disease groups. The crude infertility rate for the group was 21%. The mean number of children for the whole group was 1.7 +/- 1.3 but both men and women with Crohn's disease had significantly less children than would be expected, (men with Crohn's disease 1.5, women with Crohn's disease 1.2). There were 39 children (2% of overall births) with congenital abnormalities reported by patients with inflammatory bowel disease and in 29 cases the parents reported taking sulphasalazine (Table 3). Although this figure compares well with the 1.8% reported congenital abnormality rate for Leicestershire within the patient group in this study congenital malformations were significantly related to sulphasalazine use, z = 4.3, P < 0.0001. In conclusion sulphasalazine not only as causes morphological abnormalities in spermatozoa but may increase the chances of having congenitally abnormal offspring amongst men with IBD. The effects of other 5-aminosalacylic acids have yet to be studied in detail.

Epidemiology of inflammatory bowel disease in different ethnic and religious groups: limitations and aetiological clues.

We present a review of epidemiological studies of inflammatory bowel disease and abdominal tuberculosis in various migrant communities in the United Kingdom. The differences between various South Asian groups such as Gujaratis, Bangladeshis and Punjabis are discussed in the context of age standardisation of incidence data and various dietary and social activities.

Long-term therapy with sulphasalazine protects against colorectal cancer in ulcerative colitis: a retrospective study of colorectal cancer risk and compliance with treatment in Leicestershire.

OBJECTIVES: The aims of this study were to (i) estimate the prognosis of a 10-year cohort as expressed by risk of colectomy and risk of development of colorectal cancer, and (ii) assess the impact of long-term sulphasalazine on the natural course of ulcerative colitis. PATIENTS: One hundred and seventy-five patients diagnosed between 1972 and 1981 with either total colitis (n = 143) or with limited ulcerative colitis but deceased (n = 32) were identified. Overall there was 98% case ascertainment and verification. RESULTS: A total of 49 patients underwent a colectomy, 6 as emergency laparotomies, 36 for failed medical management and 7 for known colorectal cancer, giving a crude colectomy rate of 23.2%. The colectomy rate was 7.2% in the year of diagnosis, decreasing in frequency over the next 4 years, then reaching a steady state of approximately 1.7% per year. In the total cohort, colorectal cancer occurred in 10 patients within the study period. The cumulative incidence of colorectal cancer 10 years after diagnosis was 2.1% and at 20 years 7.4% for the total group of patients excluding those with a colectomy. The mean duration of ulcerative colitis before diagnosis was 7.9 years (range 5-12). The crude proportions developing cancer were 5/152 (3%) in the group who took long-term sulphasalazine but 5/16 (31%) in the those who had had their treatment stopped or who did not comply with therapy. This is highly significant using a simple chi 2 test (chi 2 = 20.2, df = 1, P < 0.001). Two methods were used for survival analyses, the log-rank and the generalized Wilcoxon methods. Both give highly significant values for the crude effect of compliance (P < 0.001). CONCLUSION: Patients with ulcerative colitis who were not on long-term sulphasalazine or 5-aminosalicylic acid therapy (either because a doctor stopped it or they did not comply with treatment) were significantly more likely to develop colorectal cancer than their compliant counterparts.

Does Crohn's disease need differentiation from tuberculosis?

Crohn's disease (CD) and tuberculosis (TB) of the gastrointestinal tract pose major diagnostic problems for clinicians where these conditions coexist. Clinically and radiologically, the diseases are similar. In the West, TB is considered in the differential diagnosis of all suspected cases of CD, particularly among Asian migrants. Earlier age of presentation, perianal disease and enteric fistulae favour a diagnosis of CD. Aphthoid ulceration, pseudopolyps and filiform mucosa at endoscopy are suggestive of CD and a negative tuberculin test us useful. The final diagnosis depends largely on histopathology and the presence or absence of acid fast bacilli. Tuberculosis is more common in developing countries and intestinal TB frequently coexists with pulmonary tuberculosis. TB is known to affect all age groups and fistulous communication, although uncommon, does occur. In addition to radiology and endoscopy, laparotomy may be required to establish the diagnosis. In developing countries, CD is uncommon and remains largely a diagnosis of exclusion. A trial of anti-tuberculosis therapy may often be prescribed before definitely diagnosing CD. The development of molecular biology techniques had led to a revival of interest in mycobacteria as a possible aetiological agent in CD. DNA from Mycobacterium paratuberculosis and Mycobacterium kansaii have both been identified in CD cases but the significance of this finding has not been established. However, in the near future polymerase chain reaction will become increasingly useful in differentiating CD from intestinal TB because it allows the amplification and identification of very small quantities of mycobacterium DNA.

Investigation for the prevalence of Helicobacter pylori infection in patients with gastric carcinoma in Madras, India.

The most common type of gastric carcinoma, namely the intestinal type, has been proposed to result from a precancerous process in which chronic gastritis, atrophy, intestinal metaplasia and dysplasia develop in a sequential manner. Helicobacter pylori is considered as the main cause of chronic atrophic gastritis and thus may play a role in the gastric carcinogenesis process. The present study was aimed at investigating the prevalence of H. pylori in the gastric carcinoma cases. Urease tests and ELISA developed in our laboratory and culture were used to assess the prevalence of H. pylori in the study group. The positivity of H. pylori by various tests ranged from 56.0 to 62.6% in the gastric carcinoma group and 37.3 to 46.6% in the control subjects, the difference being statistically significant. This suggests that H. pylori infection could be associated with an increased risk for gastric carcinoma, but only a very small percentage of the infected persons develops gastric carcinoma. Therefore, it is suggested that along with other critical risk factors, H. pylori may act as a cofactor in the pathogenesis of gastric carcinoma.

Comparative evaluation of cine-esophagogram with esophageal manometry in assessing esophageal motility in progressive systemic sclerosis.

BACKGROUND: Esophageal manometry is considered the gold standard in the diagnosis of esophageal motility disorders. Cine-esophagogram using barium is also a good investigation to screen patients for motor disorders of the esophagus. Comparison between these two investigations has not often been reported in patients with progressive systemic sclerosis (PSS). AIM: To determine relative merits of cine-esophagogram and esophageal manometry in detecting esophageal motor dysfunction in PSS patients. METHODS: Thirty-five patients with PSS irrespective of esophageal symptoms underwent esophageal manometry and cine-esophagogram, results and their were compared. RESULTS: Sensitivity and specificity of cine-esophagogram as compared to manometry were 96.1% (95% CI 88.7%-100%) and 55.5% (95% CI 23%-87.9%) respectively. Its positive predictive value was 86%. CONCLUSION: While esophageal manometry can identify esophageal motor disorder in PSS, cine-esophagogram can be resorted to in doubtful situations, for confirmation of diagnosis.

Incidence of chromosomal abnormalities in 153 pregnancies with ultrasound detected fetal abnormalities.

One hundred and fifty-three patients with fetal abnormalities diagnosed on ultrasound were karyotyped between January 1992 and December 1993. There were 19 (12.4%) fetuses with chromosomal abnormalities. The risk of chromosomal aberrations in the malformed fetuses were increased in the presence of intrauterine growth retardation (15.4%), oligohydramnios (20%) and polyhydramnios (25%). Fetal karyotyping is thus essential in the management of such pregnancies.
