Diagnostic value of disaccharide tolerance tests in children. Acta Paediatr Scand, 64:693, 1975.--The diagnostic value of oral lactose and sucrose tolerance tests was investigated in 61 children. A total of 105 oral disaccharide tests were carried out. When the rise in blood sugar was low, the same disaccharide was, as a control measure, instilled directly into the small intestine through a tube. This was carried out in 40 cases. In 21 patients the rise in blood sugar following the two forms of administration was correlated with the disaccharidase activity in a peroral small-intestine biopsy. The incidence of false-positive oral lactose tests was between 23 and 30%, that of false-positive oral sucrose tests between 24 and 33%. A border value of 20 mg per 100 ml in the rise of blood glucose within the first hour following a direct intra-intestinal administration affords a very satisfactory distinction between patients with and without disaccharide malabsorption. Blood glucose determinations exceeding one hour were found to be without diagnostic value.

Malnutrition is common among alcoholics because alcohol displaces protein-, vitamin-, and mineral-containing foods in the diet, and chronic alcohol consumption results in maldigestion and malabsorption of essential nutrients. In addition, alcohol exerts direct toxic effects on both the liver and gut, resulting in structural alterations in the intestine and the development of fatty liver, alcoholic hepatitis, and cirrhosis. Liver injury is preceded by an adaptive phase characterized by accelerated metabolism of drugs (including ethanol), and hyperlipemia, secondary to hypertrophy and hyperactivity of the smooth endoplasmic reticulum. Side effects include enhanced hepatotoxicity of CCI4 and possibly energy wastage. Alcoholics should not be led to beleive that correction or prevention of nutritional deficiency will prevent liver damage in the face of continued alcohol abuse.

Idiopathic late-onset immunoglobulin deficiency in a young man was associated with achlorhydria and a severe intestinal malabsorption syndrome that did not respond to conventional therapy. Combined therapy with high doses of prednisone and tetracycline hydrochloride resulted in weight gain, cessation of diarrhea, improved absorption of water, fat, and vitamin B12, and production of gastric acid after stimulation with histamine. Serum immunoglobulin levels, however, did not increase.

This report deals with the onset of Giardia-induced, primary malabsorption in patients with chronic pancreatitis. To our knowledge, this association has been reported only once previously. A further review of the literature suggests that malnourished patients with chronic pancreatitis may be susceptible to G lamblia infection. Therapy for giardiasis rapidly reverses the diarrhea, malabsorption, and edema seen in these patients.

Breath hydrogen tests were performed after a rice meal (3 g of cooked rice/kg of body weight, equivalent to 1 g of carbohydrate/kg of body weight) on 256 village children (age range 1-59 months) who were known hydrogen (H2) producers. Anthropometric measurements were made every three months and growth rates were calculated. A breath H2 excretion pattern that suggested small bowel bacterial overgrowth (SBBO), which was recognized as a transient maximum level of 10 ppm or more at 20-, 40-, or 60-min breath samples following the rice meal, was present in 53 (20.7%) children, and was more frequent in children 36-47 and 48-59 months old. This breath H2 excretion pattern was detected in 48 (33.3%) of 144 children who were rice malabsorbers (greater than 10 ppm H2 above baseline values in one of the breath samples taken between 90 and 240 min), and in only five (4.5%) of 112 rice absorbers. Children who had SBBO had a high relative risk (10.7) of being rice malabsorbers. Rice malabsorbers have a high relative risk (59.7) of having faltered growth, accompanied by a large etiologic fraction (94%). This same risk (6.68) and an etiologic fraction of 62% exist in children with untreated SBBO. These findings emphasize the need for interventions aimed at reducing the prevalence of SBBO or similar conditions as detected by the breath H2 excretion pattern to prevent rice malabsorption and growth faltering.

Medical records of 38 horses less than 1 year of age and diagnosed as having a fracture of the femoral diaphysis, metaphysis or distal physis were evaluated. Twenty-six foals had fractures of the femoral diaphysis or metaphysis with the most common fracture configuration being comminuted. Twelve foals had distal physeal fractures with the most common fracture configuration being a Salter-Harris type II. Twenty-one foals with fractures of the capital femoral physis, neck or greater trochanter during the same time period were excluded from this study. Surgical repair was attempted in 16 diaphyseal and 2 distal physeal fractures. Most of the diaphyseal fractures were repaired by placing plates on the lateral and cranial surfaces of the bone. Dynamic condylar screw plates or angle blade plates were used for increased bone purchase in 4 foals with short distal fragments. Five foals with distal physeal fractures were treated; 2 were surgically treated by placing an angle blade plate on the lateral cortex, and 3 foals with minimally displaced distal physeal fractures were managed with stall confinement. Eight of the 16 surgically repaired diaphyseal fractures healed. Fracture location and configuration was not a determinant of outcome, but the mean age of foals with successfully repaired diaphyseal fractures was 2 months compared with 4 months for the unsuccessful cases, indicating that the age and size of the foal was important. Long-term follow up revealed that 6 of the 8 successfully repaired diaphyseal fractures had no residual effects of the fracture observed during performance of the horse for its intended use. Only 1 of the 2 surgically repaired distal physeal fractures healed, but this horse was eventually killed because of unthriftiness related to a malabsorption syndrome. Some form of complication developed in 13 of the 18 surgically repaired fractures. Infection was the primary cause of failure. The greatest determinant associated with infection was the inability to control post-surgical seroma formation.

A 30 year old woman with recurrent anaemia due to folate deficiency had evidence of sarcoid granuloma on small bowel biopsy but was presumed to have Crohn's disease. The diagnosis of small bowel sarcoidosis was not seriously considered until she developed systemic manifestations of sarcoidosis (cutaneous and pulmonary lesions) over the following 20 years. Sarcoidosis of the gastrointestinal tract, particularly the small bowel, is rare and this case is unusual because bowel pathology preceded more generalised lesions. As far as is known it is also the first case to be described presenting with malabsorption of folic acid.

Mild to moderate fat malabsorption is frequently present in patients with liver cirrhosis. We investigated the influence of lactulose or lactitol treatment on fecal fat excretion in 18 patients with liver cirrhosis. All patients were Child Pugh class A or B and had not taken any therapy that could have affected intestinal absorption in the previous months. The dose of lactulose or lactitol was individually adjusted to maintain two semiliquid bowel movements per day. Steatorrhea was determined before and after a minimum of 7 days, when the cathartic effect was stabilized. Treatment with nonabsorbable disaccharides induced mild to moderate steatorrhea in 50% of patients. No differences were observed between the effects of lactulose and lactitol, but fecal fat excretion exceeded 10 g/day in two patients taking lactulose. These findings indicate that treatment with nonabsorbable disaccharides may increase fecal fat excretion in patients with liver cirrhosis. This factor should be taken into consideration when a cirrhotic patient has to take these drugs for a long time.

Individual components of milk from humans and other mammalian species may influence the severity, duration, and nutritional outcome of childhood diarrhea in different ways. Nonetheless, empirical data from clinical trials can be used to assess children's responses to specific milk-containing diets. Factors modifying the response to milk include its source, amount, frequency of feeding, type of processing, and accompanying foods, as well as the type and severity of enteric infection and specific characteristics of the host. Whereas breast-fed infants have less severe diarrhea when breast milk is continued rather than interrupted, infants and children fed with non-human milks tend to have more severe illness than those receiving milk-free or lactose-limited formulas or milk-cereal mixtures. Fermentation of milk may reduce the severity of lactose malabsorption, but additional information regarding the efficacy of yogurt in acute, childhood diarrhea is still needed.

The alpha-glucosidase inhibitors acarbose and miglitol have been successfully used to control postprandial hyperglycaemia in diabetics. They probably work by slowing carbohydrate digestion and absorption, but their effect on mouth to caecum transit time has not been studied. The effect acarbose (100 mg), miglitol (100 mg), and placebo on mouth to caecum transit time (380 kcal breakfast with 20 g of lactulose) was investigated in 18 normal volunteers using breath hydrogen analysis. Both miglitol and acarbose significantly increased breath hydrogen excretion (F2,34 = 6.31, p = 0.005) and shortened the mouth to caecum transit time (F2,34 = 3.49, p = 0.04) after breakfast compared with placebo. There was a significant negative correlation between breath hydrogen excretion and mouth to caecum transit time suggesting that with shorter transit times significantly more carbohydrates were spilled into the colon. These results indicate that alpha-glucosidase inhibitors accelerate mouth to caecum transit time by inducing carbohydrate malabsorption.
