Basic guidelines for cancer pain treatment can be found in many different handbooks published in the last years. Particularly those of the World Health Organisation published in 1986 and revised in 1996, furnish useful indication for cancer pain treatment. The authors therefore focused on resuming the most recent development in this field. In the research regarding alternative routes of administration of opioids in alternative to the oral route, the rectal administration of morphine and methadone and the transdermal route for fentanyl have proved to be efficacious. The subcutaneous route (for morphine) as well as the intravenous, peridural and subaracnoid routes, being known for some time are not taken in consideration in this paper. Various studies suggest that alternative routes are necessary in 53-70% of patients in their last days or months of live. The most frequent causes for the need to stop oral administration are dysphagia, nausea, and uncontrollable vomiting, bowel obstruction, malabsorption, cognitive failure, coma, and pain syndromes requiring anaesthetics which need be administered via the spinal route. Among the drugs, tramadol seems to be effective in the control of moderate pain. Tramadol is a centrally acting analgesic drug; it has an agonist effect on mu 1 receptors of opioids and acts also by inhibiting the re-uptake of noradrenaline and serotonine which activates descending monoaminergic inhibitory pathways. Recent clinical studies revealed that pamidronate has an analgesic effect in pain due to bone metastasis. Pamidronate is part of the biphosphonates, which are active on bone metabolism and are usually being used for the treatment of hypercalcaemia in cancer. The authors also describe briefly the indication of ketamin in association with morphine for the treatment of neuropathic pain.

A case of congenital short small bowel associated with malrotation and malabsorption in a baby girl is presented. Clinical manifestations developed in the first days after birth and consisted of diarrhea, vomiting and poor weight increase. Congenital short small bowel was suspected on radiological examination, which showed an associated malrotation. The diagnosis was confirmed by exploratory laparotomy. The length of the small intestine was only 50 cm. The intensive work of maintaining nutrition and controlling infection is described.

Since severe obesity is frequently associated with serious metabolic, cardiovascular and psychological co-morbid conditions, and given the usually unsuccessful results of conservative therapeutic approaches, surgical treatment based on gastric restriction procedures is increasingly recognized as a treatment of choice for morbidly obese persons. Among several surgical approaches designed to promote a substantial loss of weight, two gastric restriction procedures, i.e. the vertical banded gastroplasty and the gastric bypass, have been increasingly used during the past years. Both techniques induce an impressive loss of weight, and are surprisingly well tolerated, even by severely obese persons. The usual 50-75% reduction of initial weight excess, is followed by a clear-cut reduction, or even disappearance of, obesity-related co-morbidity, such as hypertension, diabetes mellitus or sleep apnea syndrome. While serious peri- and postoperative risks are very limited, the intractable vomiting occurring after gastroplasty, and potential sequelae related to iron and calcium malabsorption after the gastric bypass, represent much more frequent complications of the surgical treatment of obesity. There is also a tendency towards a late regain of weight, but the benefit in terms of improvement in the obesity-associated co-morbidity is in general maintained despite this partial increase in weight. Gastric procedures are, therefore, an effective treatment of severe obesity and of its co-morbid conditions. However, careful medical and nutritional supervision is necessary during the follow-up after surgery, to prevent potential nutritional or digestive complications.

Rotaviruses are the commonest cause of diarrhea and are responsible for more than 25% of all deaths from diarrhea worldwide. Children become infected early in life and most infections in infants older than 3 months are symptomatic. These viruses account for 18 million cases of moderate or severe disease and 900,000 deaths each year. The incidence of rotaviral disease is similar in developed and developing countries but the number of deaths is higher in developing countries. Infections occur throughout the year in developing countries but are seasonal in developed countries, occurring mainly between October and March. The mean age at first infection is 6 to 9 months in developing countries and 9 to 15 months in developed countries. The greater severity of infections in developing countries is associated with malnutrition, lower hygiene standards and the lactose malabsorption and deficiencies of zinc and vitamin A that accompany diarrhea. Many mixed infections also increase the severity of the rotavirus infection. The clinical symptoms of the disease in hospitalized patients are diarrhea, vomiting and dehydration. There is more vomiting than with bacterial infections. The severity of the clinical symptoms depends on the virulence of different strains. The disease is more severe and persistent in patients with reduced immunity. Age also has an effect. All children may have rotavirus in their feces but the percentage of children developing diarrhea is highest at an age of 3 to 6 months and decreases steadily thereafter. Rotaviruses can survive in air and may remain on surfaces for several hours. They are thus often responsible for nosocomial infections. Rotavirus was first identified in cattle in 1969. The virulence of the strain and the age of the calf at infection are important in the pathogenesis of rotaviral infection in cattle. Replacement of villous enterocytes is slow in newborn calves. This means that newborn calves are susceptible to disease caused by strains that are only moderately virulent. They are, however, protected during the first days of life by antibodies transmitted via the colostrum. There is competition between the rate of replication of rotavirus and replacement of enterocytes in older animals so only more virulent strains cause diarrhea in six-week-old calves. Adult animals become resistant to disease, but not to infection. The rotavirus genome consists of 11 segments of double-stranded RNA. Genetic recombination between these segments occurs naturally and can be reproduced in vitro. Recombinants between human and bovine strains have been identified but the epidemiological importance of this is unknown. The genomic segments encode 6 structural proteins (VP) and 5 non-structural proteins (NSP). VP6, the major capsid antigen, present can be used to identify groups of rotaviruses. The presence of VP7 indicates that the virus belongs to the G (glycoprotein) group of serotypes. There are 14 G serotypes, 10 of which can infect humans. The four main G serotypes are G1 to G4, with G1 accounting for 60% of human serotypes. The presence of VP4 identifies the P (protease-sensitive) serotype. The serotypes have different geographic distributions with G1P8 responsible for more than 50% of epidemics worldwide. The WHO project for the control of rotaviral infections focuses on avoiding fecal contamination. This is achieved by ensuring high standards of food hygiene, sewage treatment and chlorinated running water and by introducing vaccination when vaccines become available. Recombinant animal (bovine or simian) and human rotaviruses are currently being tested in phase III studies. Attenuated live human viruses, including cold-adapted strains are being tested in phase I trials. The quadrivalent recombinant rhesuslhuman vaccine had only mild side-effects in children and was effective, giving 82-92% protection against severe diarrhea over two years and 50% protection on average.

Nutritional insult after bone marrow transplantation (BMT) is complex and its nutritional management challenging. Enteral nutrition is cheaper and easier to provide than parenteral nutrition, but its tolerance and effectiveness in reversing nutritional depletion after BMT is poorly defined. Nutritional status, wellbeing, and nutritional biochemistry were prospectively assessed in 21 children (mean age 7.5 years; 14 boys) who received nasogastric feeding after BMT (mean duration 17 days) and in eight children (mean age 8 years, four boys) who refused enteral nutrition and who received dietetic advice only. Enteral nutrition was stopped prematurely in eight patients. Greater changes in weight and mid upper arm circumference were observed in the enteral nutrition group, while positive correlations were found between the duration of feeds and increase in weight and in mid upper arm circumference. Vomiting and diarrhoea had a similar incidence in the two groups, while fever and positive blood cultures occurred more frequently in the dietetic advice group. Diarrhoea occurring during enteral nutrition was not associated with fat malabsorption, while carbohydrate malabsorption was associated with rotavirus infection only. Enteral feeding did not, however, affect bone marrow recovery, hospital stay, general wellbeing, or serum albumin concentrations. Hypomagnesaemia, hypophosphataemia, zinc and selenium deficiency were common in both groups. In conclusion, enteral nutrition, when tolerated, is effective in limiting nutritional insult after BMT. With existing regimens nutritional biochemistry should be closely monitored in order to provide supplements when required.

In those who are infected with human immunodeficiency virus, poor nutritional status can result from numerous causes, including anorexia, catabolism, chronic infection, fever, poor nutrient intake, nausea, vomiting, diarrhea, malabsorption, metabolic disturbances, lack of access to food, depression, and side effects of drug, radiation, and chemotherapy treatments. A compromised immune system may not be reversed by any medical treatments at this time, but malnutrition may be prevented and reversed by using current therapies, including medical nutrition therapy that includes nutrition assessment, the development of an individualized nutrition therapy plan, and implementation of the therapy. There is substantial evidence that medical nutrition therapy saves lives, reduces morbidity, improves health outcomes, reduces costs, and shortens hospital stays.

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.

The clinical phenotype of Schimke immunoosseous dysplasia (SID) is characterized by growth retardation, renal failure, recurrent infections, cerebral infarcts, and skin pigmentation beginning in childhood. We report here on a 4-year-old male child who had all characteristic symptoms of SID, and, in addition, vomiting and prolonged diarrhea. The study results suggest that malabsorption, demonstrated as increased serum immunoglobulin A anti-gliadin antibody, steatorrhea and partial villous atrophy of the jejunal small bowel, is a previously unrecognized feature of SID.

In 1990 Scopinaro's technique of biliopancreatic diversion with distal gastrectomy (DG) and gastroileostomy was modified. A sleeve gastrectomy with duodenal switch (DS) was used instead of the distal gastrectomy; and the length of the common channel was made 100 cm instead of 50 cm. A questionnaire and a prescription for blood work were sent to 252 patients who underwent DG a mean 8.3 years ago (range 6-13 years) and 465 patients who underwent DS 4.1 years ago (range 1.7-6.0 years). The questionnaire response rate was 93%, and laboratory work was completed for 65% of both groups. The mean weight loss after DG was 37 +/- 21 kg and after DS 46 +/- 20 kg. There were fewer side effects after DS: The number of daily stools was lower (p < 0.0002), as was the prevalence of diarrhea (p < 0.01), vomiting (p < 0.001), and bone pain (p < 0.001). Greater benefits related to several aspects of life were reported after DS than DG (p < 0.0001). The mean serum levels of ferritin, calcium, and vitamin A were higher (p < 0.001), and parathyroid hormone was lower. The yearly revision rate for excessive malabsorption was 1.7% per year after DG and 0.1% per year after DS. The two procedures were equally efficient for treating co-morbid conditions such as diabetes, hypertension, and hypercholesterolemia. Biliopancreatic diversion with sleeve gastrectomy/duodenal switch and a 100-cm common limb was shown to produce greater weight loss with fewer side effects.

The authors present their experience at the Centre for the surgical treatment of morbid obesity at Milano University where since 1974, 603 obese patients underwent surgery: 312 jejuno-ileal bypass (JIB), 70 bilio-intestinal bypass (BIB), 102 horizontal gastroplasties (HGP), 44 silastic ring vertical gastroplasties (SRVGP) and 75 adjustable silastic gastric banding (ASGB). Average follow-up for these procedures is 16, 6, 11, 4 years and 24 months respectively. Weight loss is satisfactory in all cases even though the percentages vary in the different procedures. The most serious complications (severe hepatic failure, oxalic interstitial nephritis, persisting malabsorption) occurred in patients submitted to JIB. The best clinical outcome with the lowest complications rate was obtained with BIB compared to other intestinal bypasses. The most frequent complication observed in patients submitted to gastroplasties was incoercible vomiting while the most severe complications were diffuse peritonitis, secondary to gastric perforation, and peripheric neuropathy. Our experience confirms that surgical treatment of morbid obesity refractory to medical therapy is today a safe and effective treatment. BIB has still a role in super-obese young patients (BMI over 50) refusing dietary restriction lifetime. The gastric procedures, especially laparoscopic ASGB, seem to be the best option. The excellent outcome of bariatric surgery can be obtained only in specialized centers where various specialists work together.
