ABSTRACT

Information on the relative incidence of Crohn's disease and ulcerative colitis was obtained by a prospective investigation at six Melbourne teaching hospitals. One hundred and eleven patients who presented with chronic inflammatory bowel diseases between 1980-1981 were admitted to the study. Forty (36%) patients were diagnosed as having Crohn's disease and 63 (57%) patients as having ulcerative colitis. The type of chronic inflammatory bowel disease could not be determined in eight (7%) patients. These findings suggest that the relative frequency of Crohn's disease and ulcerative colitis in Melbourne hospitals is within the range that is reported for northern Europe and the United States.

ABSTRACT

This paper reports a family in which idiopathic megaduodenum occurred. The index case was a 17 year old male with lifelong steatorrhea, episodic vomiting of food consumed days before, offensive belching, and recurrent abdominal pain and distention. The diagnosis was made by a barium meal examination, but only after a failed small bowel biopsy suggested some anatomical abnormality. Direct questioning about family members then revealed that his father, aged 43 years, had similar symptoms and a subsequent barium meal confirmed the diagnosis. Screening of the family revealed megaduodenum in the 20 year old sister who was totally asymptomatic and had normal fecal fat levels but an abnormal breath test. The remainder of the family members were asymptomatic and had normal radiology. This family, in which idiopathic megaduodenum occurred in three of six members, is reported because it illustrates some of the features of idiopathic megaduodenum and chronic idiopathic intestinal pseudo-obstruction. It also demonstrates the need to investigate the families of apparent sporadic cases. Such investigation may uncover additional symptomatic and asymptomatic individuals who may be presenting diagnostic difficulty, and who, by virtue of an early diagnosis, may be spared unnecessary surgery.

ABSTRACT

The influence of smoking on duodenal ulcer healing was examined during a double blind study of 83 patients randomly allocated to oxmetidine or cimetidine treatment. Smoking habits were recorded but patients were not advised to change these. Smokers and nonsmokers were similar clinically and did not differ in compliance with medication. Both H2-receptor antagonists were equally effective and after four weeks of treatment ulcers were healed in 76% of patients. Ulcer healing occurred significantly less frequently in smokers (69%) than nonsmokers (89%). Smokers with healed ulcers consumed fewer cigarettes per day (mean +/- SE: 15.8 +/- 1.4) than those whose ulcers did not heal (22.2 +/- 2.7). When smokers were grouped according to daily cigarette consumption, a direct relationship was found between increasing cigarette consumption and decreasing frequency of ulcer healing. No reduction in ulcer healing was apparent in patients who smoked nine cigarettes a day, or less.

ABSTRACT

There are conflicting reports on the influence of cigarette smoking on healing in patients with duodenal ulcer; some studies show an adverse effect on healing rate and others no effect. This study reports the influence of smoking on short-term healing and relapse rate in 135 patients with duodenal ulcer who were treated with cimetidine (90), ranitidine (25), and oxmetidine (20), all powerful H2-receptor antagonists. Ulcer healing and relapse were documented endoscopically and all studies were performed in a double-blind manner. In the short term, 95% of nonsmokers healed compared with 63% smokers (p less than 0.01) and there was a positive correlation between failure to heal and number of cigarettes smoked. During a 12-mo follow-up examination after healing and on no treatment, 53% of nonsmokers and 84% of smokers relapsed (p less than 0.01). These results show that smoking adversely affects healing of duodenal ulcer with H2-receptor antagonists and that continued smoking leads to a higher relapse rate.

ABSTRACT

The effect of ranitidine, a new H2-receptor antagonist, on the healing of duodenal ulcer has been assessed in a double-blind study. Fifty patients with endoscopically proven duodenal ulcer were randomly assigned to ranitidine 150 mg twice daily or placebo for 4 weeks. Endoscopic examination at this time showed that 20 of 25 patients (80%) on ranitidine healed compared to 4 of 25 patients (16%) on placebo (P less than 0.01). Smoking adversely affected the incidence of healing: 70% of nonsmokers healed compared to 30% of smokers (P less than 0.03). There were no side effects noted on ranitidine. Review at 6 months after cessation of therapy showed relapse of duodenal ulcer in 10 of 20 patients (50%) healed with ranitidine and 1 of 4 patients (20%) healed with placebo. Thus, ranitidine (300 mg/day) produces similar healing rates to those reported for cimetidine (1000 mg/day); also like cimetidine, the incidence of healing on ranitidine is adversely influenced by smoking and the relapse rate on cessation of therapy is high.

ABSTRACT

Fifty consecutive patients with symptomatic endoscopically proven duodenal ulcer were randomized double-blind to Mylanta II or cimetidine treatment schedules. Smoking habits were noted, but patients were not advised to alter these. Healing was determined by reendoscopy at 6 wk. Eighty percent of patients on active cimetidine and 52% on active Mylanta II had healed at 6 wk (not significantly); 85% of nonsmokers healed compared to 44% of smokers (p less than 0.03). In smokers, cimetidine achieved healing in 50%, Mylanta II in 39% (not significantly); while in nonsmokers, cimetidine achieved healing in 100%, Mylanta II in 67% (not significantly). These results indicate a significant and equally adverse effect of smoking on the healing rate of duodenal ulcer achieved by either cimetidine or Mylanta II.

ABSTRACT

During a prospective six year study from 1972-1978 there were 894 admissions to a haematemesis and melaena unit. In 162 admissions bleeding was due to acute gastric ulceration, an incidence of 18%. The group comprised 157 patients, five patients being admitted on two occasions. There were 12 deaths (7%), seven after surgery and five in conservatively treated patients. A significant fall in incidence of admissions was noted in the final two year period of study. The reason for this is unknown as no other cause of haematemesis and melaena showed a similar fall in incidence. In addition over this two year period patients with acute ulceration followed a more benign course and required surgery less often.

ABSTRACT

A prospective study of patients with upper gastrointestinal bleeding admitted to a haematemesis and melaena unit has revealed an incidence of Mallory-Weiss tears of 8% (59 of 762 patients undergoing endoscopy). Prior vomiting was present in 60% and an associated upper gastrointestinal lesion in 44 percent. The majority of patients had a recent ingestion of alcohol and/or analgesics, whilst 34% had chronic heavy alcohol intake. Approximately 50% of patients required no blood transfusion, while 37% had over three units of blood. No patient in the group required surgical intervention, and one patient died because of general debility. This study suggests that the Mallory-Weiss tear accounts for a significant proportion of patients admitted with upper gastrointestinal bleeding, but that the mortality and morbidity are low.
