RESUMEN
AIM: Given the demographic shifts and needs of cost rationalization, it is of high priority to organize health care on the basis of ambulatory outpatients models. The aim of this study was to examine activity at the gastro-hepatology outpatients clinic of the Molinette Hospital. In this facility, the management is based on a work team organization that follows cohorts of patients with specific pathologies. METHODS: All services, consultations and urea breath test (UBT) for the diagnosis of Helicobacter pylori infection, carried out from January 2003 to December 2006, were extrapolated from the computerized system. Consultations were divided into first examination and controls. Furthermore, the destination of the patients after each consultation was considered. RESULTS: During the year 2003, 8 842 consultations and 4 071 UBT were carried out, in the year 2004, 11 342 consultations and 2 409 UBT, in the year 2005, 12 474 consultations and 2 510 UBT, in the year 2006, 12 249 consultations and 2 357 UBT. No further specialistic management was required for 25% of patients, while 2% had been hospitalized in the bed unit, 3% in the short hospitalization unit or the day-hospital. The remaining 70% were included in work teams or monitored thereafter. The comparison with consultations from 1994 shows an increase due to both first examination (+300%) and controls (+83%). CONCLUSIONS: The burden of the requests from the population and primary care structures addressed to the outpatients clinic of gastro-hepatology is relevant. The activity of this facility leads to a low rate of hospitalization as well as of cost reduction.

Paraoxonase, an enzyme associated with high-density lipoprotein (HDL-PON), exerts a protective effect against oxidative damage of circulating cells and lipoproteins, modulates the susceptibility of HDL to atherogenic modifications such as glycation and homocysteinylation, and even exerts an antiinflammatory role. The aim of the present study was to investigate the relationship between lipoprotein oxidative stress and the activity of HDL-PON in healthy and obese subjects. Therefore, the activity of HDL-PON and the levels of lipid hydroperoxides in HDL and low-density lipoprotein (LDL) isolated from plasma of obese females (n = 12) and age-sex-matched controls (n = 31) were compared. Our results demonstrated for the first time that the activity of HDL-PON in obese subjects was significantly lower compared with that in controls (P < 0.001). Moreover, our results showed a significant increase in the levels of lipid hydroperoxides in HDL and LDL isolated from obese subjects (P < 0.001). The negative correlations established between HDL-PON activity and the levels of lipid hydroperoxides associated with HDL and LDL confirm the relationship between paraoxonase activity and lipid peroxidation of lipoproteins. Plasma levels of leptin correlated negatively with HDL-PON activity and positively with levels of lipid hydroperoxides in HDL and LDL of obese subjects, suggesting a relationship between leptin and oxidative damage of lipoproteins. In conclusion, our study demonstrated that the increase in oxidative stress in LDL and HDL of obese subjects is associated with a decrease in HDL-PON activity. The lower paraoxonase activity and the compositional changes in HDL and LDL could contribute to the greater risk of cardiovascular disease associated with obesity.

Urea urinary nitrogen (UUN) and total urinary nitrogen (TUN) were determined in 15 patients to study their relationship mainly in highly catabolic patients. The subjects were: 7 multiple trauma, 3 autologous bone-marrow transplant, 1 tetanus, 4 postcholecystectomy patients; 180 determination were made, 111 of which in highly catabolic phase (TUN > 15 g/day). TUN and UUN are well correlated (r = 0.9742; p < 0.001) in the range 3 to 52 g/ day of TUN. Urea represents the 83.2 +/- 9.4% (M +/- SD). A double-linear formula to calculate TUN from UUN is proposed (for UUN 15 g/ day: TUN = UUN x 1.17 + 0.7; for UUN > 15 g/ day: TUN = UUN + 4). The least square procedure was used to compare the differences between measured and calculated TUN, and the results obtained with the proposed double-linear formula were compared with that obtained employing pre-existing formulas (Lee's and Mackenzie's). Considering all ranges of values studied (3-52 g of TUN) the results obtained were significantly different (p < 0.005); dividing the levels of TUN in 15 g; 16-29 g and 30 g, the results were always better, but the statistical significancy was not always reached.
RESUMEN
OBJECTIVE: Viral infections of the mesenteric microvascular endothelium have been hypothesized as pathogenetic factors in inflammatory bowel diseases. The aim of this study was to determine whether immunoglobulin M (IgM) antibody against measles virus is associated with disease. PATIENTS AND METHODS: The IgM antibody was detected by indirect antibody test in 36 patients with evidence of Crohn's disease (23 males and 13 females, median age 40 years, range 20-66), 22 patients with ulcerative colitis (14 males and 8 females, median age 42 years; range 19-65), 59 patients with a chronic active hepatitis (35 males and 24 females, median age 56 years, range 38-77) and 30 blood donors (20 males and 10 females, median age 45 years, range 29-62). RESULTS: Twenty-eight of 36 patients (78%) with Crohn's disease and 13 of 22 patients (59%) with ulcerative colitis tested positive as compared to only 3 of 89 (3.3%) controls (P < or = 0.001). CONCLUSION: The detection of IgM anti-measles virus in the majority of patients with Crohn's disease and in about half of ulcerative colitis patients as compared to a very low prevalence in patients with other chronic inflammatory disease is consistent with the hypothesis that the measles virus has pathogenetic implications in inflammatory bowel diseases.

Percutaneous endoscopic gastrostomy (PEG) is the preferred method of long-term tube feeding, but only a few studies describe a long-term follow-up. The purpose of this study is to analyze the follow-up of PEG enteral feeding patients in the long term, and to report on the complication and survival rates. Between January 1991 and June 1995, we studied 136 patients (49% cancer and 51% non-cancer patients; male = 68%, female = 32%) after PEG insertion. One hundred twenty-eight patients had a long-term follow-up of over 31 d. The mean duration of PEG feeding was 277 +/- 358 d (range 31-1590): 17% of patients returned to oral feeding, 34% continued enteral nutrition, and 49% died. Major complications occurred in 3% of the patients: 1 aspiration pneumonia, 1 subcutaneous abscess. 2 buried bumper syndrome. Minor complications arose in 14% of our cases: 8 tube blockages, 4 tube dislodgements, 6 site infections. For the whole group of 136 patients, survival probabilities after PEG insertion at 1, 6, 12, and 24 mo were 90.5%, 52%, 42%, and 35%, respectively. After 180 d, the difference in survival probabilities between cancer and non-cancer patients became significant (P < 0.02). Median survival probability was 64% for non-cancer and 39% for cancer patients, and this trend did not change over 2 y.

BACKGROUND: Extrapyramidal syndrome and alterations in brain magnetic resonance images are described in patients undergoing long-term home parenteral nutrition (HPN) and in cholestatic patients. These abnormalities have been correlated to basal ganglia manganese (Mn) accumulation. METHODS: A longitudinal 1-year study was conducted on 15 patients undergoing HPN (median duration, 3.8 years; range, 1.7-10; median Mn parenteral supplementation, 0.1 mg/d). Whole-blood, plasma, intra-erythrocytes, and urinary Mn concentrations were measured and brain magnetic resonance was performed at the beginning (time 0) and after 1 year of Mn intravenous supplementation withdrawal (time 1). No patients showed psychosis, extrapyramidal syndrome, or cholestasis. RESULTS: At time zero, 10 of 15 patients (67%) showed paramagnetic accumulation on cerebral magnetic resonance images; at time 1 there was a reduction of cerebral Mn accumulation. In all patients, blood-Mn levels were significantly reduced after 1 year of Mn intravenous supplementation withdrawal. CONCLUSIONS: Patients receiving long-term HPN showed an elevated incidence of alterations in brain magnetic resonance images with a median Mn intravenous supplementation of 0.1 mg/d. Mn supplementation withdrawal significantly decreased metal levels in blood and brain storage. We noticed that the intra-erythrocyte Mn level was a good index of Mn status.

BACKGROUND: Indication for home parenteral nutrition (HPN) in cancer patients is controversial because intestinal failure and malnutrition are often only two of the many problems found in such patients that may deserve priority of treatment. METHODS: This was a retrospective study of 75 cancer patients from nine institutions included in the Italian HPN Registry. The patients had a mean weight loss of 12.5%, serum albumin of 3.1 g/dL, lymphocyte count of 1150/mm3, and serum total iron-binding capacity of 190 micrograms/dL. The main indication for HPN was intestinal obstruction (66%); 72% of the patients had metastatic disease. A series of demographic, oncologic, and nutritional characteristics were analyzed in an attempt to predict a possible benefit of HPN. RESULTS: A total of 9897 days of HPN were delivered to 75 cancer patients, for a median of 4 months (range 1 to 15 months) per patient. Sixty-nine patients died while receiving HPN, five had a remission of their intestinal failure, and one chose to stop the treatment. Complications related to parenteral nutrition were as follows: 19 cases of sepsis, 6 catheter occlusions, 4 catheter dislocations, and 2 metabolic imbalances. HPN preserved nutritional status and slightly improved weight, lymphocyte count, serum albumin, and Karnofsky performance status in patients who survived > 3 months. Quality of life during HPN was judged by the clinicians to have improved in only 9% of those who survived < 3 months, but in 68% of the patients who survived for > 3 months. Karnofsky performance status > 50 at the start of HPN was correlated with longer survival (p = .02). CONCLUSIONS: Our study demonstrated a positive effect of HPN on nutritional status and quality of life in patients who survived > 3 months and suggests that HPN should be avoided when Karnofsky performance status is < 50.

Little is known about body composition in Parkinson's disease (PD). We studied 35 patients (20 male, 15 female subjects; mean age 69.7+/-5.8 years) with advanced PD by anthropometry, dual-energy X-ray absorptiometry (DEXA), and serum 25-OH vitamin D measurement. Over 70% of patients had a disease duration of more than 4 years; all were on L-dopa treatment. Low levels of serum 25-OH vitamin D were present in 41% of the patients. The mean body mass index (BMI) was 25.3+/-4.3 kg/m(2) (range 17.1-37.3). Mid-arm muscle circumference was below the 10th percentile in 23%. For whole-body mean (+/-SD) bone mineral density, the T score was below -1 SD in 35% of patients, and the Z score was below -1 SD in 24%. Percent fat mass measured with DEXA was 30.6+/-11.4% (range 10.1-45.5) in the overall sample; it was 21.1+/-8.8% (range 10.1-30.4) in male subjects and 38.1+/-9.2% (range 25.8-45.5) in female subjects. We conclude that advanced-stage PD may show excess adiposity coexisting with depletion of lean body mass (sarcopenic obesity), in addition to decreased whole-body bone mineral density associated with low serum 25-OH vitamin D. A low level of physical activity and inadequate exposure to sunlight are likely to be among the putative causes.

Sixty four patients, following severe acute brain injury were fed according to a strict dietetic therapy at the Intensive Care Unit at the Institute of Neurological Surgery, University of Turin. We used mixtures composed of simple nutritional elements consisting of carbohydrate as glucose polymers from 7 to 15 units, free aminoacids and MCT oil, integrated with natural elements. The solutions were administered via a nasogastric tube with the maximum caloric intake of 6.000 Kcal and 186 grams proteins/24 hr. After recording a series of hematochemical and clinical parameters we obtained the following results: 1) the average blood sugar level was always found to be pathological among the 11 patients who eventually died during their hospitalization, while 30% of the discharged patients had normal blood sugar values; 2) kidney function was significantly more affected among eventually deceased patients than among discharged ones; 3) the hospitalization time had a negative influence on the hepatic functions. Total serum albumins and proteins cease their decline respectively at average values of 2 and 5.5% gr, cholesterol maintains a constant level between 180 and 200% gr, calcium between 8 and 9 mg% and phosphorous around 3 mg%. Alkaline phosphatase in all patients rose significantly to pathological values only after a week of hospitalization. All other tests presented an irregular course. The survival period of our group of patients was significantly longer than that of control group. Within our group the survival rate was better among patients who received, within 10 days from cerebral damages, a hypercaloric and hyperprotein diet of more than 5.000 Kcal and 120 grams of proteins in 24 h, as compared to those whom the same diet was administered more gradually or following a longer period of time after having sustained cerebral damage.

Glutamine is a non essential amino acid. Nevertheless it has to be considered a "conditionally essential" amino acid for several metabolic reactions in which it is involved. Glutamine is the most abundant amino acid in human plasma and muscle. Because glutamine is highly unsteady, it was never used for enteral and parenteral nutrition in the past. It appears to be a unique amino acid for rapidly proliferating cells serving as a preferred fuel compared to glucose. It seems to be essential for cellular replication such as a "nitrogen carrier" between the tissues. A deficiency state of glutamine causes morphology and functional changing and negative nitrogen metabolism. The need for glutamine is particularly high when metabolism is increased as in the critically ill (surgical stress, sepsis, inflammatory states, fasten, burns) especially in the tissues with a rapid cell turn-over. In these conditions the body requirements of glutamine appear to exceed the individual's muscle deposits (muscle is the most important place of synthesis and storage), causing an increased synthesis with a high energy waste and loss of muscle mass. Glutamine is essential for bowel mucosa trophism and its deficiency in all the catabolic states allows bacterial translocation. In these cases feeding is not sufficient to restore basal conditions. At present enteral or parenteral glutamine supplementations are of high interest for the feeding of critically ill patients.

The results of restructuring the meals service in Ivrea Hospital are reported. 7 diet-sheets with food prepared by the central kitchen composed: 2 of normal nutritional content (the first cooked with normal ingredients; the second using special recipes for the bed-ridden); one hypoprotein (50 g/24 hrs of protein), one hypoglycidic (145-170-210 g/24 hrs of glycides), 1 hyposodic (0.6-1.4 g of N/24 hrs), one semiliquid and one divided into 6 small meals. Special diets were needed for 0.5-6-12-2-0.1% of the patients. The amount of uneaten food fell (from 30% to 10%) and there was a real increase in calories (1390 leads into 1870 cals/24 hrs) and protein consumption (70-95 g/24 hrs). The cost remained the same (2079-2176 lire/per day/per capita).

The aim of the study was to evaluate the effectiveness of dietetic-behavioural and pharmacological treatment on 32 patients with high level hypercholesterolemia (LDL-c greater than 160 mg/dl) over 14 months. Clinical and laboratory tests were performed at time 0 (enrollment), at time 1 (after 2 months dietetic-behavioural treatment only), at time 2 and time 3 (after 6 and 12 months respectively of combined dietetic-behavioural and pharmacological treatment). The dietetic-behavioural treatment consist of reduced intake of saturated fatty acids, cholesterol and rapidly absorbed glycid; increased intake of omega-3 fatty acids and fiber; reduced overall calorie intake. The patients were also advised to take light daily exercise. The pharmacological treatment (sinivastatin 20 mg/die) was given to patients whose total cholesterol levels were over 250 mg/dl after 60 days of dietetic-behavioural only treatment and then continued for the whole study. The result showed an average reduction of 20% (p less than 0.01) in LDL-c in all patients after dietetic-behavioural only treatment and a further 20% (p less than 0.01) reduction after 12 months of combined treatment. There was therefore confirmation of the validity of dietetic-behavioural and pharmacological treatment during our study.

Wilson's disease is a hereditary disorder of biliary copper excretion. Most often the disease presents with hepatic and neurological involvement. In the hepatic forms, hypocerulo-plasminemia, the determination of eye copper and the dosage of copper in serum, urine and liver tissue are all leads to diagnosis. The presentation and the biochemistry may direct the diagnosis of the acute forms. Treatment differs according to the clinical patterns. Early diagnosis in the asymptomatic patient leads to chelating therapy to prevent copper overload. Chronic disease may benefit from chelation and liver transplant. Transplantation is the cure for fulminant forms. We report three young women with Wilson's disease; one had a fulminant form and was transplanted and the other two responded to chelation therapy. Family screening allowed the identification of an asymptomatic sibling.

The aim of this investigation was to compare, in a randomized short-term study the effects on some parameters evaluating lipid metabolism, nutritional status and immune function of two different patients. Particularly, the influence of the intravenous (i.v.) infusion of a fat emulsion on above-mentioned parameters was evaluated. The two regimens (G and GL) were isocaloric (about 30 kcal.kg-1.d-1 non protein energy) and isonitrogenous (about 0.27 g.kg-1.d-1 nitrogen); the only difference was the source of non-protein calories administered. Regimen G consisted of glucose-based TPN (100% of non-protein energy as glucose) whereas, in regimen GL (glucose-lipid-based TPN), the 55% of non-protein caloric supply was given as glucose and 45% as lipids. 9 of the patients were randomly assigned to receive regimen GL (group GL) and 8 to receive regimen G (group G). TPN was delivered through a central vein catheter for 8 days; during this period no hepatic or metabolic complications have been observed. Clinical and laboratory tests were performed at day 0 (enrollment), at day 4 (after 4 days of TPN) and at day 8 (at the end of TPN). Both regimens of TPN were able to induce an improvement of the nutritional status and serum prealbumin (TBPA) significantly increased in all patients (p < 0.05). The results of the immune measurements showed that no significant change in immune function during the administration of either regimen occurred. However, in group GL, we observed a slight, non significant change in the percentage numbers of T-cells subpopulations that resulted in a decrease in the ratio of helper to suppressor T-cells (H:S). Serum lipids and lipoprotein profile didn't change significantly in group GL. On the contrary, in group G, we observed a significant decrease in serum concentrations of HDL cholesterol (p < 0.05), LDL cholesterol and apo A1 (p < 0.01) while total cholesterol remained unchanged; a non significant rise in serum triglyceride also occurred, These results show that the two regimens had a similar impact on nutritional status in both groups. The i.v. infusion of the fat emulsion didn't alter lipid profile and was not associated with an impairment of some aspects of the immune function. In conclusion, our results confirm that fat emulsions represent an important component of i.v. nutritional support regimens and should continue to be used when and where indicated in short-term TPN. However, long-term effects of i.v. infusion of fat emulsions on the immune systems should be further investigated, in a more substantial number of patients.

UNLABELLED: 50 patients suffering from dysphagia and oesophageal stenosis were treated in the period 1975-77. Of these 31 had renutrition of longer than two weeks and are the subject of the present study. Three nutrition systems were employed: 1) total parenteral feeding (7 patients), 2) feeding by naso-gastric tube or gastric fistula (15 patients), 3) feeding per os with semiliquid foods (9 patients). The patients were suffering from benign cicatricial stenosis (5), tumours of the cardia (7), tumours of the oesophagus (19). Short-term survival, weight behaviour and the course of certain blood parameters (Hb, GR, cholesterol, albumin, total proteins) are reported. CONCLUSIONS: --in benign cicatricial stenosis and tumours of the cardia, a normal protein-caloric amount (2000-3500 KCal., 80-120 g/24 h of proteins) is sufficient to obtain weight increase and stabilization of blood examinations. The administration route is unimportant; --in malignant stenosis, 4000-6000 KCal. and 100-130 g of protein/24 h must be provided to obtain the same result. In patients treated with total parenteral nutrition the weight loss persists. The reason for this behaviour is not known; it is likely that enzymatic blocks exist in substrate utilization; --further study is needed to improve results obtained and to clarify the reasons for such behaviour.

A study was made of 20 patients with "resistant" obesity selected from a series of about 4000 observed between 1970 and 1976 in an assessment of the possible existence of features distinguishing such patients from those who respond to treatment and display a satisfactory decrease in weight. The group was marked by a higher incidence of familial obesity, earlier onset of overweight, and certain personality features (evaluated by psychometric tests). Their blood sugar and insulin curves, blood cholesterol and uric acid, adipose tissue cellularity, and blood pressure (LHAP) were similar to those in the general series. Whereas their blood triglyceride values were normal, however, those in the general series were up by 21%. It is therefore felt that the clinical tests used at present do not enable the "resistant" obese subject to be distinguished. "Resistant" obesity may well constitute a distinct nosological entity, but one that is only identifiable via the patient's response to treatment.

The collateral effects of antineoplastic therapy often lead to a deterioration of the cachectic condition induced by the presence of the tumour itself. This study analysed the effects of a programme of dietary surveillance/support in patients with non-Hodgkin's lymphoma undergoing a cycle of MACOP-B polychemotherapy. During the entire course of therapy patients were followed weekly by a nutritional specialist and a dietician in order to assess and if necessary modify food intake, also in relation to the onset of collateral effects. Using this programme it was observed that a satisfactory nutritional state was maintained during the entire cycle, with an increased food intake compared to the start of the cycle and to conditions of good health.

The use of total parenteral nutrition (TPN) in bone marrow transplant recipients is well recognized. These patients, as a result of treatment with chemotherapy and immunosuppressive agents, undergo catabolic stress. In stressed patients attention has been focused on the optimal calorie: nitrogen ratio of total parenteral nutrition formulations. Theoretically, TPN formulas of low calorie: nitrogen ratio impede body protein catabolism. In bone marrow transplant patients negative nitrogen balance may persist despite high nitrogen intake. The purpose of the present study is to determine the effect of increasing nitrogen intake on nutritional and metabolic parameters in bone marrow transplant patients. The metabolic effect of an increased nitrogen dose during TPN was studied in 33 bone marrow transplant patients, divided into 2 groups. Patients were given total parenteral nutrition formulas providing a protein intake of 1.4 +/- 0.2 g of protein/kg IBW/day for the first group, and 2.3 +/- 0.12 g of protein/kg IBW/day for the II group. Total calories, non protein and protein, were held constant at 40 kcal/kg IBW/day for all patients. Data have been calculated for 4 weeks starting from the first week pretransplant. As we had expected, the patients who are the object of the present study were well nourished at the time of hospital admission, confirming the description of bone marrow transplant recipients published by other transplant centers. Relative body weight, total serum protein, albumin, prealbumin and cholesterol were not significantly different at any study period.(ABSTRACT TRUNCATED AT 250 WORDS)

Elderly is particularly at risk of malnutrition: he is not able to feed himself adequately, it is then important to attain correct intakes using also artificial enteral nutritional techniques (nasogastric tube, gastrostomy, etc.). These techniques may lead to complications (ab ingestis pneumonia, metabolic complications, alvus disorders): the use of artificially nutrition in the elderly must be carefully evaluated. 257 patients (M = 180, F = 77) aged 65 or more, mainly affected by neoplastic diseases (n 195) and by neurological and vascular diseases (n 62). The feeding route were evaluated in this study: 74% by nasogastric tube, 13% by gastrostomy, 11% by jejunostomy. In a group of 55 patients similar concerning clinical and nutritional conditions we evaluated at the beginning of enteral feeding and four months later, caloric/protein intake, body weight and plasmatic albumin. In patients fed by nasogastric tube a mean intake of 1300 +/- 365 Kcal n.p./die, with a protein rate of 58.5 +/- 16.9 g/die was attained; by gastrostomy 1450 +/- 324 Kcal n.p./die and 65.5 +/- 16 g/die; by jejunostomy 1219 +/- 398 Kcal n.p./die and 53.3 +/- 21 g/die. The compliance to enteral nutrition was well in 37% of patients night administration was performed. Clinical complications: nausea and vomiting were observed in 9 patients with nasogastric tube, in 1 patient with gastrostomy and in 3 patients with jejunostomy; diarrhea has been noticed in 6 patients with nasogastric tube and in 1 patient with jejunostomy. Mechanical complications; nasogastric tube (n 189): 35 displacements, 7 breakages, 4 obstructions; pharyngostomy (n 6): 2 displacements and 1 obstruction; gastrostomy (n 33): 3 displacements; jejunostomy (n 29): 2 misplacements.(ABSTRACT TRUNCATED AT 250 WORDS)

Day Bed Unit at the Department of Gastroenterology. Experience of a study group. We analyzed the activity of the Day-Bed Unit at the Department of Gastroenterology of Turin Hospital (Molinette). The quality of the service provided and the days of stay in hospital for each admission were evaluated in terms of cost benefit ratio. The average stay in hospital for each admission was 2.57 days as opposed to 9.3 in the in patient ward. Patients were divided in subsets according to the cause of admission. Stratifying the patients according to diagnosis showed a hospital stay of 2.73 days for liver disease and of 2.81 for pancreas and biliary disease. Among the admissions for liver disease, pre or posttranspiant patients required 2.89 days as opposed to 2.62 days of those who were treated for esophageal varices. Thus, the cause of admission was a factor influencing length of hospital stay. Patients needing non surgical treatment for liver cancer took 2.22 days if treated with percutaneous ethanol injection; those undergoing chemoembolization required 2.93 days. In conclusion, the day bed unit has proven to be able to provide a service with a good cost benefit ratio. Patients admitted to this service may be withdrawn from the waiting list of the in patient ward, thus reducing the waiting time. Optimization of this service needs integration with the surroudings Units within the Department and in the Hospital.
