Background And Aims: Bleeding from diffuse esophageal ulcerations can be difficult to treat. Hemospray is a hemostatic powder, and its mechanism of hemostasis is thought to be through concentrating clotting factors and forming mechanical plugs on bleeding vessels.
Methods: The authors present 3 consecutive cases of diffusely ulcerated esophagus with clinically significant bleeding.
This pictorial essay describes the most characteristic lesions and radiologic signs of Crohn disease of the small bowel: nodular lymphoid hyperplasia, abnormal mucosal folds, villous pattern, aphthous ulcerations, linear ulcerations, cobblestone pattern, string sign, target sign, comb sign, creeping fat, sinus tracts, fistulas, and abscesses. Each description includes the definition, a correlation with the pathologic findings, an explanation of the possible physiopathologic mechanism, sample radiologic images with air enteroclysis or MDCT, the correspondence with the endoscopic findings when possible, and a list of differential diagnoses.

The medical history, especially when it reveals the use of salicylates, is critical when considering this diagnosis. Unfortunately, the neurologic and systemic effects of salicylate toxicity may hinder the ability to obtain a reliable medical history.

Aim: Three strains of lactic acid bacteria were studied for their pharmacokinetics in the human gastrointestinal tract.
Methods: The survival of the strains was studied up to the ileum in six subjects each, after ingestion of 150 g of fermented milk.
Lactose maldigestion has been under intensive research since its discovery in the 1960's. We know the prevalence of lactose maldigestion in a great number of countries and ethnic groups. However, there is often no provision made for the secondary type of maldigestion, and the study populations have sometimes been selected rather than picked at random.

We examined the relations among IBS, demographic factors, living habits, and lactose intolerance. On the basis of a lactose tolerance test with ethanol, 101 of the 427 healthy subjects studied were lactose maldigesters and 326 were lactose digesters.

It is not known whether lactose-intolerant subjects should consume full-fat or high energy milk instead of half-skimmed milk. In this study, breath 13CO2 and hydrogen (H2) measurements were combined to assess simultaneously the effect of increasing milk energy content on gastric emptying, digestion, and tolerance of lactose.

Design: Subjects recorded intolerance symptoms using a visual analogue scale (VAS) following ingestion of three test milks for varying fat content for a two-day period.
Subjects/setting: The subjects were thirty adult volunteers, patients of two Estonian out-patient clinics with diagnosed lactose intolerance.
The possibility of delaying gastric emptying and improving lactose digestion and tolerance by increasing milk viscosity was studied in 13 lactose maldigesters who ingested three test milks with different viscosities (range: 33-1892 mPa.s) in random order at intervals of 1 wk. Each test portion was 500 mL and provided approximately equal to 1900 kJ and 18 g lactose.

Design: Measurement of breath hydrogen (H2) concentration and of clinical symptoms after consumption of the test meals.
Setting: Metabolic ward for healthy volunteers, INSERM U290, Hôpital St.
In this study we examined whether small doses of lactose induced symptoms in 39 lactose maldigesters and 15 lactose digesters in a randomized, crossover, double-blind design. The test doses were 200 mL fat-free, lactose-free milk to which 0, 0.5, 1.
