The present study is a follow-up of 34 cases admitted to a paediatric department with recurrent abdominal pain (RAP) in 1942 and 1943. 45 persons without a history of RAP were selected at random and included as controls. Using a questionnaire, there was a higher incidence of gastrointestinal symptoms among persons with a history of RAP during childhood than among controls (P less than 0.05). 18 of the original 34 cases who still had symptoms were re-examined; 11 had a clinical picture consistent with a diagnosis of irritable colon, 5 had a picture compatible with both irritable colon and peptic ulcer/gastritis, and 2 had duodenal ulcer. Abdominal pains occurred no more frequently among children of parents who had had RAP during childhood than among children of parents without such a history. However, there was a higher incidence of abdominal pain among children of parents who were complaining of abdominal discomfort at the time of the investigation than among children whose parents were without such symptoms (P less than 0.005).

The association of diverticulosis with a thickened muscle wall in the pelvic colon is well known. There appeared to be a possibility that this muscular thickening might give rise to the rectosigmoidal mucosal puckering often seen through a sigmoidoscope. In 278 colonic motility studies, mucosal puckering was correlated with patient age, diverticulosis, and the symptomatology of the irritable colon syndrome. The prevalence of mucosal puckering increased with age at the same rate as that of diverticulosis, but the different percentage levels were reached some 25 years earlier in life. Mucosal puckering, which persisted in all subsequent examinations, showed no correlation with the clinical characteristics of irritable colon syndrome. Resistance of the bowel wall to distention was significantly greater in association with puckered rectosigmoidal mucosa than when the mucosa appeared smooth. It is concluded that rectosigmoidal mucosal puckering is probably caused by thickening of the underlying muscle; it is a precursor of diverticulois, and patients who have it should be kept on a high-residue diet.

Differential measurements of small and large bowel transit times were performed in 13 subjects iwth a radiotelemetering pressure-sensitive capsule incorporating less than 10mugCi of 51-Cr. Six patients had constipation. The other seven patients had diarrhoea due to the irritable bowel syndrome (3), following vagotomy and pyloroplasty (3), or due to laxative abuse (1). This new method enables the gastric, small intestinal, and colonic transit times to be measured differentially in the same subject. The capsule can be localized in the gut lumen by reference to the characteristic pressure pattern and in relation to bony landmarks by the radioactive marker as frequently as desired without recourse to radiographs. The results show that gastric emptying and small intestinal transit did not differ in constipation and diarrhoea. By contrast the mean colonic transit was significantly faster (P smaller than 0.01) in diarrhoea whatever the cause (17.5 plus or minus 4.1 hours) than in constipation (118 plus or minus 4.1 hours).

The irritable bowel syndrome is one of the commonest conditions seen in gastroenterology clinics. The diagnosis is suggested by the presence of longstanding colonic symptoms without any deterioration in the patient's general condition but depends essentially on the exclusion of any underlying organic disease. Particular care is required before attaching this label to middle-aged and elderly patients presenting with bowel symptoms for the first time. The most important aspects of treatment are firm reassurance, a simple explanation of symptom production and sympathetic follow-up. Drug therapy plays a comparatively minor role although a variety of preparations are helpful in individual cases. Reinvestigation is rarely indicated unless the symptom complex changes or the patient loses weight.

The 'irritable bowel syndrome' is a disorder of civilisation, in which a low-residue fibre-deficient diet is probably the major aetiological factor. This is illustrated by the first 2 Black patients presenting with this syndrome. They represent a population which has only recently changed from a rural to an urban way of life.

Small intestinal lactase activity in the health adult is either the same as in early infancy or may drop to very low levels. The behavior of the enzymatic state varies with the ethnic group studied. In those adults with low lactase activity little information is availalbe as to the age at which the lactase decreases. We attempted to determine a) the frequency of low intestinal lactase activity and b) the age at which the change occurs. For this purpose we reviewed in a large number of intestinal biopsies both histologically as well as for disaccharidase activities. The biopsies were obtained from a heterogeneous group of Caucasians, including patients, their siblings and parents. The patients were those with failure to thrive in whom no organic cause could be elicited, and those with the irritable colon syndrome. Patients ranged in age from 6 weeks to 50 years and out of a total of 1, 077 jejunal biopsies, 172 morphologically normal biopsies were selected. The milk drinking habits of 118 subjects and their families were elicited and 31 oral lactose tolerance tests performed. The mucosal lactase activity and sucrase-to-lactase ratio in those 172 individuals were plotted against age. In the first 3 years the mean lactase activity was 32.1 plus or minus 10.1 mumoles/g protein per min and the sucrase-to-lactase ratio was 1.7 plus or minus 0.5 with no change from year to year. However, after age 5 two separate groups emerge. A small group (24.6% of the population) with low lactase activity, and a second group possessing the same mean value for lactase activity as noted in the first 3 years. The low lactase activity group included children and adults with clinical lactose intolerance. These individuals consumed relatively small amounts of milk and when 12 of them were tested with an oral lactose tolerance test the result was a "flat" curve with a maximum rise in blood glucose of 9 plus or minus 3.2 mg/100 ml. The second group consumed more milk averaging 1 quart/day with no discomfort and when 19 were tested with oral lactose tolerance tests the values were normal. This study indicates that low lactase activity in the Caucasian population may make its appearance at the age of 5 years.

Constipation and diarrhea are usually defined in terms of frequency of defecation and consistency of stool. However, the subjective component in these symptoms is so great that the objective criteria cannot be satisfactory. An important additional aspect is provided by the analysis of sensations and postures in the three phases of the act of defecation (announcing, emptying, subsequent phase). Taking account of the subjective aspects may contribute to a better differentiation and classification not only of constipation and diarrhea but also of such disturbances as organic rectal disease and irritable colon.

The author states that aside from two major digestive psychosomatic conditions, peptic ulcer and ulcero-hemorragic colitis, one only encounters in the adult a widespread psychosomatic pathology, that is to say: 1 degree phenomena of hysterical conversion (gravidic vomiting for example); 2 degrees digestive phenomena concomitant with emotional reactions (diarrhea and anxiety, hypersecretion and anger, constipation and depression etc.); 3 degrees digestive manifestations accompanying anxiety neurosis; 4 degrees authentic functional diseases, such as the irritable colon corresponding to a well defined personality structure. The author concludes this article by some considerations of psychosomatic symptoms observed by the psychoanalyst; he specifically relates the role of the body barrier, the implication of reality and finally the very particular fantasies found in these psychosomatic patients.

The 14C-glycocholate breath test was performed in 15 normal subjects and 134 patients clinically suspected of bacterial overgrowth in the proximal small intestine, with functional impairment of the ileum and chologenic diarrohea as well as other forms of diarrhoea. In addition, faecal weight, faecal fat excretion and faecal bile-acid excretion were measured. Early and highest 14CO2 expiration peaks were found as an expression of increased deconjugation of bile acids in patients with fistulae between proximal small intestine and colon, and in 13 of 24 patients with Billroth II gastric resection or duodenopancreatectomy. Bile-acid deconjugation was not increased in sprue, chronic pancreatitis with steatorrhoea, ulcerative colitis, irritable colon, Whipple's disease, Salmonella enteritis, non-specific enteritis, or laxative abuse. In six of twelve patients with Crohn's disease of the ileum there was an increase in deconjugation of bile acids.

Twenty-nine consecutive outpatients with irritable bowel syndrome were given structured psychiatric interviews, as were 33 consecutive medical controls who did not have irritable bowel syndrome. All were from an internal medicine group practice. Seventy-two percent of irritable bowel syndrome subjects had psychiatric illness, with hysteria and depression the most prevalent syndromes. Only 18% of controls had psychiatric illness. The primary physician made an accurate psychiatric assessment in only 28% of the subjects. An awareness of his patient's psychiatric illness is necessary for the physician to provide effective treatment, as for depression, and to spare the patient needless medications, hospitalizations, and surgery, as with hysteria.
