Thirteen patients, following a bilio-pancreatic diversion procedure for obesity, developed severe nutritional complications such as protein deficiency, anemia, hypocalcemia and/or gastrointestinal problems (uncontrollable diarrhea). They were subjected to a new therapeutic approach-the administration of pancreas extract tablets Viokase, containing protease, lipase and amylase. This, together with protein-rich food resulted after 2-4 weeks of treatment in a drastic reduction in the number of daily stools: from 10-12 per day to 4-6 per day, as well as the disappearance of the accompanying foul smell and the malodorous gas emissions. After a further 4-8 weeks of treatment of those patients with protein deficiency, the serum protein-albumin levels as well as the Hgb and Ca levels rose to near normal values: protein from 4.8-5.5 g % to 6-6.5 g %; albumin from 1.8-3 g % to 3.4 g % and above; Hgb from 7-9 g/di to 11-12 g/di; and Ca from 7.5-7.8 mg% to 8-9 mg%. None of the patients treated with pancreas extract for protein deficiency required rehospitalization for intravenous protein replacement, nor was there any need observed for operative revision or takedown in these patients.

A probiotic is a viable microbial dietary supplement that beneficially affects the host through its effects in the intestinal tract. Probiotics are widely used to prepare fermented dairy products such as yogurt or freeze-dried cultures. In the future, they may also be found in fermented vegetables and meats. Several health-related effects associated with the intake of probiotics, including alleviation of lactose intolerance and immune enhancement, have been reported in human studies. Some evidence suggests a role for probiotics in reducing the risk of rotavirus-induced diarrhea and colon cancer. Prebiotics are nondigestible food ingredients that benefit the host by selectively stimulating the growth or activity of one or a limited number of bacteria in the colon. Work with prebiotics has been limited, and only studies involving the inulin-type fructans have generated sufficient data for thorough evaluation regarding their possible use as functional food ingredients. At present, claims about reduction of disease risk are only tentative and further research is needed. Among the claims are constipation relief, suppression of diarrhea, and reduction of the risks of osteoporosis, atherosclerotic cardiovascular disease associated with dyslipidemia and insulin resistance, obesity, and possibly type 2 diabetes. The combination of probiotics and prebiotics in a synbiotic has not been studied. This combination might improve the survival of the bacteria crossing the upper part of the gastrointestinal tract, thereby enhancing their effects in the large bowel. In addition, their effects might be additive or even synergistic.

The purpose of this case-control study was to identify predictors of obesity among Puerto Rican children from Hartford, CT. The study included 53 prepubertal children, 31 girls and 22 boys, between 7 and 10 y of age. Children were classified as obese [n = 29, body mass index (BMI) >/= 85th percentile] or controls (n = 24, BMI < 85th percentile). Multivariate logistic regression analyses indicated that frequency of fruit juice consumption [odds ratio (OR), 95% confidence interval (CI); 4.02, 1.48-10.95], hours of daily TV viewing (1.86, 1.02-3.42), maternal BMI (1.39, 1.10-1.77) and lower dairy product intake (0.41, 0.19-0.93) were associated with obesity. Television viewing was correlated (P < 0.05) with lower physical activity in girls, and with higher snacking frequency and sweets consumption in boys. Obese children were more likely than controls to have higher systolic and diastolic blood pressures and to have experienced more ear infections and diarrhea during the previous year. Results provide evidence of the multifactorial nature of childhood obesity in this community.

From 1984 in N.N. Burdenko Surgical clinic of I.M. Sechenov MMA more than 500 horizontal gastroplasties (HGP) were performed for the treatment of patients with extreme degree of alimentary-constitutional obesity. In 1996 for the first time in our country HGP was performed, including laparoscopic method, with use of regulated silicon bandage "Lap-Band" (LB) made by "Bioenterics", USA. Laparoscopic HGP was performed in 29 patients (7 males, 22 females), aged from 23 to 60 years, mean age was 34.2 +/- 10 years. Minimal body weight was 85 kg, maximal--180 kg, mean--131 +/- 27.2 kg. Mean body mass index was 47 +/- 9.9 kg/m2. Open operations were performed in 14 cases, laparoscopic operations--in 15 cases. 11 laparoscopies were performed in initial stages in very stout patients and in the absence of laparoscopic equipment. In 3 cases the conversion from laparoscopic to open operation was necessary: in 1st case because of hemorrhage from lesser omentum's vessels, when hemostasis cannot be performed by laparoscopy; in 2nd case as a result of bronchospasm associated with tense pneumoperitoneum in the patient with bronchial asthma; in 3rd case because of significant enlargement and rigidity of liver left lobe, which didn't permit to create the space for manipulations in cardial portion of the stomach. The mean bed day turnover after traditional HGP with LB and after laparoscopic HGP was 12.2 and 5.4 respectively. Intraoperative complication was observed in one case--hemorrhage from lesser omentum's vessels. One complication was observed in immediate postoperative period, on the 6th day after traditional HGP: the eventration as a result of hard diarrhea due to antibacterial treatment was diagnosed. One more complication was observed in a year after traditional HGP: small stomach evacuatory function disorders as a result of its significant dilatation. These disorders occurred because of gastric mucosa inflammatory edema, decrease of anastomosis diameter and frequent vomiting due to aspirin taking. In this case the repeated operation--bandage's reposition was performed. There were no other complications. The rate of repeated operations was 4% which agrees with literature data.

The Magenstrasse and Mill (M&M) procedure for obesity is designed to preserve normal gastric emptying mechanisms. The hypothesis investigated in this study was that gastric emptying would be normal after the M&M gastroplasty. Gastric emptying studies were performed using both liquid and solid test meals, in ten morbidly obese patients (MO group) and in 13 patients after the M&M procedure (MM group). Seven people of normal weight served as controls and were matched for age, sex and height to the M&M and MO groups. Three years after the M&M procedure, mean (SD) weight loss was 42 (19) kg, with a mean loss of excess weight of 58% (20%). Gastric emptying half-times (t 1/2) are expressed in minutes, as median values (25th and 75th percentiles). The t 1/2 for solids was 97 (85-110) min in the control group, 140 (86-220) min in the MO group and 79 (46-150) min in the MM group. Median gastric emptying for solids was 0.7% (0.6%-0.8%) per minute in the control group, 0.5% (0.3%-0.8%) in the MO group and 0.9% (0.4%-1.4%) in the M&M group. There were no statistically significant differences in the emptying times of the three groups. It is concluded that the M&M procedure achieves acceptable weight loss, while preserving gastric emptying mechanisms and thus minimising possible side-effects such as vomiting, dumping and diarrhoea, which are common complications of gastric bypass procedures.

In the past year there have been many advances in the area of small bowel physiology and pathology and therapy. In preparation for this review, over 1500 papers were assessed. The focus is on presenting clinically useful information for the practising gastroenterologist. Selected important clinical learning points include the following: (1) glucose absorption mediated by SGLT1 is controlled by mRNA abundance, as well as by posttranscriptional processes including protein trafficking; (2) inducers of cytochrome P-450 decrease glucose and fructose absorption and increase glucose consumption in the intestine; (3) the regulated release of nutrients from the stomach into the upper intestine ensures that the modest intestinal transport reserve capacity is not exceeded; (4) hepatocyte growth factor and short-chain fatty acids may enhance intestinal adaptation and prevent the atrophy seen when total parenteral nutrition is infused; (5) inhibitors of pancreatic lipase and phospholipase H2 may be useful clinically to reduce absorption as part of a treatment program for obesity and hyperlipidemia; (6) several membrane-bound and cytosolic proteins have been identified in the enterocyte as well as in the hepatocyte and may be the target for the future therapeutic manipulation of bile acid metabolism and control of hyperlipidemia; (7) suspect bile acid malabsorption in the patient with otherwise unexplained chronic diarrhea; (8) a proportion of lipid absorption is protein-mediated, and this opens the way to targeting these proteins and thereby therapeutically modifying lipid absorption; (9) a high protein diet may be useful to increase the intestinal absorption of drugs transported by the H+/dipeptide cotransporter; (10) a metal transporter DCT1 has been identified, and this may open the way to a better understanding of disorders of, for example, iron and zinc metabolism; (11) the nutrient transporters such as SGLT1 are responsible for a portion of the intestinal absorption of water; (12) the influence of nitric oxide on intestinal water absorption and secretion depends on its concentration; (13) a trial of bile acid-sequestering agent may prove useful in the treatment of the patient who experiences diarrhea while taking an enteral diet; (14) a proteolytic extract from pineapple stems may prove to be useful to treat diarrhea, although the mechanism of this effect remains to be established; and (15) the antisecretory effect of the new peptide, sorbin, needs to be tested in a clinical situation on patients with diarrhea. Other new and promising antidiarrheal agents include bromelain, an extract from pineapple stems, and igmesine, a final sigma ligand.

The association between long haul travel and the risk of venous thromboembolism are suspected for long time. Mostly air travel related thrombosis series have been reported in the literature. Risk factors can be classified as: 1. travel related factors (coach position, immobilization, prolonged air travel, narrow seat and room, diuretic effect of alcohol, insufficient fluid intake, dehydration, direct pressure on leg veins, rare inspiration). 2. air plane related risk factors (low humidity, relative hypoxia, stress). 3. patient related factors (hereditary and acquired thrombophylia, previous deep venous thrombosis, age over 40, recent surgery or trauma, gravidity, puerperium, oestrogen containing pills, varicosity, chronic heart disease, obesity, fever, diarrhoea, vomiting, smoking). No patient related factors were found in some cases. To reduce the hazards air travellers are rightly concerned to know the level of the risk and the airlines should be responsible for this information. People should discuss with their physician what prophlylactic measures should be taken, such as compression stockings or low molecular weight heparin. Not only flight but car, bus and train travellers are also at risk of developing venous thromboembolism. Long haul travel alone is a separate risk factor for venous thromboembolism.

Three decades ago, the observations of Trowell and Burkitt gave rise to the "fibre theory", in which it was contended that there was a link between the consumption of a diet rich in fibre and non-processed carbohydrates and the level of protection against many of the "first world diseases" such as constipation, diverticulosis, cancer of the colon, diabetes, obesity and cardiovascular disease. Since that time, numerous studies have been presented to analyze the relationship between fibre and disorders of the gastrointestinal tract and other processes with severe health implications. The present revision looks at the experience accumulated over this period regarding the importance of the consumption of fibre for certain phatologies. It not only deals with the epidemiological relationship existing between fibre intake and the development of diseases such as cancer of the colon or cardiovascular disorders but also reviews the interest of fibre a therapeutic agent, in view of the current information available on its different mechanism of action. Thus the possibility of using soluble fibre has taken on renewed interest for the treatment of inflammatory intestinal disease, for control of diarrhoea, in irritable bowel syndrome or no modulate the concentrations of glycaemia or cholesterol. Three is a discussion of the discrepancies found between the consumption of fibre and diverticular disease, the treatment of constipation and the association with obesity and cardiovascular disease. Despite the accumulated evidence on the consumption of fibre, there is currently no consensus as to recommendations on what type of fibre and the optimal amount that should be consumed. A high fibre intake (> 25-30 g/day) based on a variety of food sources (fruit, vegetable, legumes, cereals) is the only way to avoid many of the disorders mentioned. The consumption of a particular type of fibre (soluble or insoluble) is limited to the treatment of certain processes, because its individual relationship with many disorders is still pending determination.

In the last few decades, the consumption of soft drinks (fruit juices and beverages) in Spain has increased considerably. From 1991 to 2001, consumption of soft drinks increased by 41.5 %, that of extract-based drinks by 62.1 % and that of juices by 26.7 %. Consumption increases with age, with teenagers drinking twice as much (740 ml/day) as pre-school children (388 ml/day). High consumption of soft drinks may lead to underconsumption of foods and drinks of high nutritional quality, such as milk. Multiple studies relate this phenomenon with the risk of growth retardation, failure of non-organic growth, diarrhea produced by alterations in carbohydrate absorption, allergy, pharmacological interactions, obesity, atherothrombotic lipidic profile, alterations in glucose and bone mineral metabolism and negative effects on dental health. Because excessive consumption of soft drinks favors a diet of low nutritional quality, intervention and prevention strategies should be established to promote water and milk as the basic drink in children's and teenagers' diets while soft-drinks should be consumed only occasionally.

Galanin, a 29-30 amino-acid neuropeptide is distributed in the central and peripheral nervous systems, the pituitary gland, the gastrointestinal tract and also in the pancreas. The endogenous and exogenous effects of galanin are mediated by three receptor subtypes, which are termed: GALR1, GALR2, and GALR3. Galanin has a significant role in physiological and pathological processes in adults as well as in children. It has an ability to contract smooth muscles in GI (facilitation and inhibition), stimulates reflexes in the CNS, decreases pancreatic amylase secretion, changes transport of electrolytes Na+ and CL-. It takes part in etiopathogenesis of depression, Alzheimer's disease and diarrhoea, exerts tonic inhibition of nociceptive input to the central nervous system and regulates a function of hypothalamic-pituitary system. Galanin decreases insulin and somatostatin secretion, increases glucagon secretion, takes part in prolactin release, stimulates growth hormone-releasing hormone, hypothalamic gonadotropin releasing hormone and corticotropin releasing hormone. It causes increase of somatotropin secretion, luteinizing hormone and foliculotropin release and adrenocorticotropin secretion. The hypothalamic galanin takes part in etiopathogenesis of obesity not only in human reproductive period, but also in adolescence, increasing the appetite and changing fat metabolism. This variety of actions emphasizes the potential importance of this peptide in the regulation of cells function and the need to understand the mechanism by which they act.
