Four patients with a long history of abdominal swelling, colic pains and diarrhoea were cured by a fructose-free diet. They were all given an oral load of (14C) fructose and their expiratory excretion of 14CO2 was found to be significantly lower than that of control patients with similar symptoms. It is concluded taht the patients cured by a fructose-free diet might have a partial fructose malabsorption.

In this review I have described the pathophysiology of allergic disorders of the gastrointestinal tract. Situations where the intestine cannot be a complete barrier to foreign allergens and antigens were discussed and etiological factors of gastrointestinal allergy were detailed. Clinical features of gastrointestinal allergy include diarrhea, vomiting, abdominal pain and colic, intestinal hemorrhage and malabsorption as well as symptoms and signs outside the gastrointestinal tract such as chronic rhinitis and asthma in the respiratory system, urticaria, angioedema and eczema as dermatological signs, headache, insomnia, hyperkinesis as central nervous system manifestations, failure to thrive and anaphylaxis as constitutional reactions. Milk allergy was discussed as an example of food allergy. Immunology of the gastrointestinal tract was presented, with examples of four types of hypersensitivity reactions, and gastrointestinal disturbances of immunodeficiency disorders and syndromes were named. Lastly, the autoimmune mechanism and the gut were described, with particular discussion of ulcerative colitis as an example of an autoimmune disease.

Of 59 infants with jejunoileal atresia, seven presented with absence of mesentery, the main superior mesenteric artery ceasing to exist beyond the origin of the right colic or ileocolic artery, and a helical ileum. This distinctive form of jejunal atresia has been recognized with increasing frequency in recent years. Distal to the atresia, the small bowel receives its blood supply retrograde from an artery derived from the ileocolic or right colic arcades, and the ileum coils around its nutrient artery in an "apple peel" or "Christmas tree" deformity. The first three patients in this report died. The lastion, but they recovered as their malabsorption gradually disappeared. The treatment includes resection of the dilated bowel, as in other atresias. Resection of part of the distal bowel may be required for additional atresias or for poor vascularity with questionable viability. Postoperative malabsorption generally requires intravenous hyperalimentation.

Aspecific chronic diarrhea is one of the most common causes of protracted diarrhea in infancy. The pathology is characterised by an increased frequency of daily bowel movement with half-formed feces; it is not associated to malabsorption syndrome or enteric infections and appears to be correlated to an unbalanced diet and changes in microflora involved in the fermentation processes. A controlled randomised single-blind clinical trial was performed, using commercially available crystalline lactulose and lactic enzymes, in order to normalise the modified intestinal ecosystem. Twenty-four children (mean age 21.76 months) affected by aspecific chronic diarrhea were studied; weight and height parameters were not influenced. Patients were first divided by age and then randomly divided into two groups of 12. Group 1 received treatment with crystalline lactulose (Laevolac crystals, BBR) and Group 2 received lyophilised Lactipan. In both cases treatment continued for 15 days. At the end of the trial all subjects showed a complete remission of intestinal disorders. Children in Group 1 showed more fully formed feces following treatment. Fecal pH values were considerably reduced only in those subjects treated with crystalline lactulose. In the latter subjects H2 excretion diminished during the trial, a fact which may probably be attributed to reduced colic pH values. On the basis of these results, it is possible to conclude that both treatments proved efficacious. The re-establishment of a balanced intestinal ecosystem remains the choice treatment for subjects affected by aspecific chronic diarrhea.

The series of physiopathologic consequences and the adaptive response that appears in the residual intestine following intestinal by-pass surgery has been widely studied. The same is not true for the ascending colon. Having demonstrated the adaptive changes this organ undergoes after a massive enterectomy, we carried out the present study to evaluate the compensatory reaction after an intestinal by-pass. A total of 115 Wistar rats weighing 350-550 g were used. Twenty animals made up group 0 (control), 30 underwent intestinal section (group II) and 65 received a jejuno-ileal by-pass (group III), with latero-lateral anastomosis. After weight control was performed the animals were sacrificed at 15, 30, 45 and 60 days, and samples were taken from the ascending colon for optical microscopy (OM), scanning electronic microscopy (SEM) and transmission electronic microscopy (TEM). All objective data were quantified and statistical studies carried out. The by-pass animals showed statistically significant ponderal drops (p less than 0.001), an expression of the malabsorption disorder the by-pass produced. Groups 0 (control) and I (IS) showed no macroscopic, microscopic or ultrastructural changes. The by-pass animals, however, manifested colic dilatation with a significant increase in thickness, to the detriment of the muscularis and mucosa, and greater crypt depth with a relative decrease in the number of goblet cells. Enterocytes increased in number and size. These changes were statistically significant in relation to groups 0 and I. The above findings were confirmed ultrastructurally. In the scanning electronic microscopy after 30 days, the colic mucosa had an irregular appearance, with elevations but no foliated appearance.(ABSTRACT TRUNCATED AT 250 WORDS)

A patient with isolated fructose malabsorption presented with diarrhoea and colic during the first year of life and subsequently responded to a fructose free diet. Fructose malabsorption has been implicated in some cases of irritable bowel syndrome in adults and may also be an infrequently recognised cause of gastrointestinal symptoms in children.

In 122 healthy newborn infants, we studied the relationship between breath hydrogen (H2) production after feedings containing lactose (human milk or commercial formula) in colicky and noncolicky infants at 6 weeks and 3 months. Eighty-three infants (68%) developed colic (mild, moderate, or severe) by 2.6 +/- 1.8 weeks of age (mean +/- SD). Zero time (baseline) breath H2 values were significantly higher in colicky compared with noncolicky infants at both 6 weeks (40.6 +/- 41.4 vs 14.8 +/- 32.9 ppm) and 3 months (27.7 +/- 38.1 vs 8.5 +/- 18.2 ppm). There were significantly more positive breath H2 tests in colicky compared with noncolicky infants at 6 weeks (78% vs 36%) and 3 months (89% vs 45%). Failure to produce H2 throughout the breath H2 test was significantly more frequent in noncolicky compared with colicky infants at 6 weeks (50% vs 18%) and 3 months (43% vs 4%). These findings remained significant even when infants with mild colic (at 6 weeks and 3 months) were included in the noncolicky group. We conclude that colicky infants produce more breath H2 in the fasting state and in response to feedings containing lactose than noncolicky infants produce. This may represent increased lactose malabsorption, differences in colonic bacterial fermentation conditions, or differences in the handling of colonic gas produced.

Surgery does not cure Crohn's disease, but only its complications, as the recurrence rate that requires a new intervention is 6% per year. The resections performed by the surgeon should be as limited as possible, in order to avoid the consequent malabsorption. The identification of two forms of Crohn's disease, with different aggressiveness, has found that the stricturoplastic is an encouraging way of treatment for those forms with a prevalent stenotic component. A lot of studies have evaluated the relationships between recurrences and resections on margins microscopically free or affected by the disease. The aim of this study was a retrospective verification of the influence of any possible microscopical residue of the disease on the recurrence rate, evaluating whether the two different forms of aggressiveness of the disease (presence of stenosis or fistula) can influence the rate and precocity of the recurrence onset. In 37 patients operated for the first time of ileal or ileocolic resection, the overall recurrence rate was 18.9%; neither the presence of microscopically affected margins nor the presence of fistulas or stenosis has showed to have an influence on the onset of the recurrences. The only data that emerged is a greater precocity of the onset of recurrence in those patients whose disease was characterised by the presence of enteric fistulas. The forms in which fistulas and perforations were evident showed a recurrence rate not significantly higher than that of forms with stenosis only, but the period of time free from the disease was notably longer for the latter. In the end, patients in which typical granulomas were present showed a recurrence rate of just 9%, compared to 23% of patients in which granulomas were absent. MATERIALS AND METHODS. From 1980 through 1992, 61 patients affected by Crohn's disease were operated. There were 39 men and 22 women (mean age: 40.4 years). The mean length of the follow-up was 55.5 months. It was the first operation for 43 patients, while 9 had already undergone surgery in other hospitals; 9 patients showed anorectal complications. The operations performed on the patients for the first time have been ileal resection in the following localizations: duodenum-jejunum 4, jejunum and ileal 34, colic 5; the recurrences treated have been ileal-jejunum in 7 cases and colic in 2. In 2 cases of recurrence a stricturoplastic has been performed. RESULTS. The operative mortality was of 3 patients: 2 due to sepsis for anastomotic dehiscence and 1 to systemic mycosis. Four postoperative fistulas were observed. Recurrence of the disease occurred in 13 patients (26.5%), specifically in 21.4% of the patients operated for the first time and in 57.1% of those that were operated for recurrences. DISCUSSION AND CONCLUSIONS. In the treatment of Crohn's disease, it is important to identify any possible group with high risk of recurrence in order to undertake an appropriate medical prophylaxis. The results concerning the presence of microscopical disease on the resection margins are today still controversial. Some groups of authors prefer wide resection margins, some others are in favour of restricted resections. Our considerations let us assert that in those patients in which the resections have been performed on margins with microscopic presence of the disease, the interval before the recurrence occurs is not significantly shorter than that of patients with free margins. But the patients suffering from Crohn's disease with fistulae, probably need medical post-operative therapy to delay recurrences onset.

A case report of a young patient (born in 1980) with a 2-year history of chronic ulcerative proctocolitis was described. Checking colonoscopy 6 months from the beginning of disease showed multiple and even confluent polypoid lesions in transverse gut starting from hepatic flexure in addition to diffuse inflammatory rectosigmoideal changes. Biopsy found only colic mucosa without any tumorous structures. Five months later the patient's state got worse accompanied instantly by vomiting, weight loss and malabsorption symptoms. A duodenocolic fistula was supposed according to gastroduodenoscopy and biopsy. Because of progressive suffering of the patient colectomy with ileoduodenoanastomosis and ileosigmoidoanastomosis was performed. Polypous lesions were observed from the blind gut up to descendent colon and a transversoduodenal fistula was proved. The removed part of gut was completely changed into a dense network of elongated polypous lesions. In microscopy, bigger polyps showed an inner stromal part often with bands of smooth muscle cells covered by nearly normal gut mucosa. Smaller polyps were formed by hypertrophic gut mucosa only. At the base of polyps, a stagnation of gut contents was found as well as ulcerous defects of various depth. Macroscopy and microscopy of polypoid lesions formed by non-neoplastic gut mucosa were those of so called bizzare ("giant") inflammatory polyposis of the gut. Up to now the patient's clinical picture and local finding in the stump of resected gut have been typical for chronic ulcerous colitis and polypous lesions were not revealed by checking investigations.

Giardiasis is a cosmopolitan parasitosis. Diarrhea, abdominal colic, and flatulence are the main clinical symptoms, however, malabsorption, and impairment of growth of children may occur. The 5-nitroimidazoles are the drugs of choice in the treatment of giardiasis. Methods: The efficacy and tolerability of secnidazole and tinidazole were evaluated in a randomized, open-label, clinical trial performed with 267 Giardia lamblia-positive children. Secnidazole, in a new gel formulation, and tinidazole suspension were prescribed as single oral doses of 30mg/kg and 50mg/kg, respectively. Clinical and parasitological follow-up was carried out before, and at 7, 14, and 21 days after treatment. Results: Clinical cure was observed in 77.3% and 75.7% of the patients in the secnidazole and tinidazole groups, respectively. Parasitological cure was obtained in the 91.3% and 89.6% in the secnidazole and tinidazole groups, respectively. A metallic taste after drug ingestion was more commonly reported in the tinidazole group than in the secnidazole group (p<0.05). Conclusions: The authors conclude that both secnidazole gel and tinidazole administered as a single oral dose are effective treatments for children with giardiasis since both high cure rates and good tolerability were observed.
