Abstract
Children undergoing surgical removal of tumors in the posterior cranial fossa can encounter a varied and complex constellation of neurological symptoms, called cerebellar mutism, defined as a disturbance in the planning and programming of motor language with preserved understanding, behavioral disorders such as inattention, visual-spatial disorganization, personality change, as well as ataxia and dysmetria. In the last years, several groups have been trying to establish risk factors or even predictive scores in order to be able at least in part to predict the appearance of speech disorders before surgery. We report on a child with pilocytic astrocytoma of the cerebellar vermis who had already been diagnosed with developmental linguistic delay two years earlier. This disorder initially worsened after surgery and later improved in the following 12 months. The aim of this paper is to emphasize the importance of preoperative neuropsychological evaluation. The present case, along with those reported in the literature, suggests that the risk of long-term cerebellar mutism is higher in children with preoperative speech disorders. In these patients a thorough assessment of cognitive and linguistic functions is therefore necessary to better evaluate the risk of cerebellar mutism after surgery.

Abstract
Low plasma concentrations of docosahexaenoic acid (DHA) are reported in unsupplemented cystic fibrosis (CF) patients. Forty-one CF patients aged from 6 to 12 years were randomized to receive high-dose DHA (100 mg/kg/day in the first month and 1g per day thereafter through a 12-month supplementation) or placebo (germ oil). Primary outcome was percentage change in plasma AA:DHA ratio. Secondary outcomes were changes in the number of pulmonary exacerbations compared to previous year, lung function, BMI, skinfold thicknesses, and body composition assessed by DXA and in serum concentrations of C-reactive protein, cytokines and vitamin (α-tocopherol and retinol). Compared to the control group plasma AA:DHA ratio decreased in the intervention group after 6 months (median percentage changes: -73% in the intervention group vs. -10% in the control group, P=0.001). No differences were detected between groups for secondary outcomes. Despite a decrease of the AA/DHA ratio, DHA supplementation for one year did not induce any significant biochemical and clinical improvement in CF patients.

Abstract
Intestinal function in children with very short bowel syndrome and related intestinal failure may improve after isolated liver transplantation. An infant with an ultrashort gut, ileo-cecal valve, and whole colon received total parenteral nutrition from the first days of life. Enteral feeding failed because of the progressive dilatation of the jejunal portion and motility disorders. He developed early severe cholestatic liver disease (aspartate transferase 186, alanine transferase 103 U/L, serum bilirubin 8.4 mg/dL) and subsequent liver failure. At 8 months of age, he benefited from isolated liver transplantation (left segment graft from living donor). His early posttransplant evolution was characterized by recovery of oral alimentation, improvement of digestive and absorption functions, but he did not achieve TPN-independence. At 20 months, 50% to 60% of his energy needs were covered by parenteral nutrition and he has satisfactory growth indices (3rd percentile for weight and height), reduced stool volume, and frequency. Isolated liver transplantation allowed, in this particular case, time for further intestinal adaptation thereby avoiding the need for intestinal transplantation early in life.

Abstract
Several reports have indicated that fecal elastase-1 (EL-1) determination is a new, sensitive, and specific noninvasive pancreatic function test; however, very few patients with malabsorption due to small intestine diseases have been included in the previous studies. The aim of the study was to compare the diagnostic accuracy of fecal EL-1 and fecal chymotrypsin (FCT) in distinguishing between pancreatic maldigestion and intestinal malabsorption. Three groups of subjects were studied: group A included 49 patients with known cystic fibrosis (25 males, median age 5 years); group B included 43 subjects with various small intestine diseases (17 males, median age 6 years); and group C included 45 children without any history of gastrointestinal disease (22 males, median age 5 years). In all patients, stools were collected for 72 h on a standard diet and fecal EL-1, FCT, and steatocrit tests were performed. Both EL-1 and FCT were below normal limits in all CF patients with pancreatic maldigestion not treated with pancreatic enzyme (100% sensitivity for both assays); El-1, but not FCT, was also below normal in all the CF patients with pancreatic maldigestion treated with pancreatic extracts. Both EL-1 and FCT values in the CF group were significantly lower than in subjects with various small intestinal diseases and in children without any history of gastrointestinal disease (P < 0.0001). FCT, but not EL-1, values showed an inverse statistically significant correlation with steatocrit values in the whole CF group (P < 0.001); FCT was below normal in three of four CF patients with steatorrhea on pancreatic enzyme therapy. Both EL-1 and FCT had 100% specificity when calculated in children without any history of gastrointestinal disease; in contrast, specificity was 86% for EL-1 and 76% for FCT if we considered the control group with small intestinal diseases: low EL-1 was observed in two cases of intestinal giardiasis, two cases of short bowel syndrome, one case of celiac disease, and one case of intestinal pseudobstruction; FCT was abnormal in four cases of intestinal giardiasis, three cases of celiac disease, one case of short bowel syndrome, one case of Crohn's disease, and one case of intestinal pseudobstruction. Diagnostic accuracy was 92% for fecal EL-1 and 82% for FCT. Steatocrit values were over the normal limit in 11 patients with small intestine diseases; in 7/11 of these patients at least one of the pancreatic test results was below the normal limit. In conclusions, in patients with CF, fecal EL-1 determination is not more sensitive than FCT in identifying pancreatic maldigestion; however, fecal EL-1 assay is more specific than FCT determination in distinguishing pancreatic maldigestion from intestinal malabsorption.

Abstract
BACKGROUND Pancreatic exocrine insufficiency is a common condition in patients with cystic fibrosis. Large amounts of pancreatic enzyme supplements are required to reduce malabsorption but patient compliance is not always optimal. AIMS To compare patients' preference and the efficacy of two enteric coated microsphere preparations in patients with cystic fibrosis. PATIENTS Patients with pancreatic exocrine insufficiency due to cystic fibrosis. METHODS Patients were assigned to the crossover treatment with Creon or Pancrease for 1 week and then to the alternative treatment. Patients had to follow a fixed diet (at least 2 g fat/kg) and had to assume 1000 units lipase/g fat. The evaluation parameters were: patients' preference, acceptance of therapy, stool fat excretion, stool weight, gastrointestinal symptoms, and tolerance. RESULTS AND CONCLUSIONS Of the 33/60 patients who expressed a preference for one of the two treatments, 30 preferred Creon while only 3 patients preferred Pancrease (p<0.001). No difference between the two treatments was observed regarding stool characteristics, gastrointestinal symptoms and tolerance. The mean number of capsules taken daily was reduced by 35% with Creon. The results of this study showed a preference in favour of Creon probably due to the reduction of daily capsule intake of 35%, supporting digestion as well as Pancrease.

Abstract
BACKGROUND The majority of patients with cystic fibrosis today reach adulthood. During adolescence, however, many ask themselves questions regarding their possible future realisation. AIMS The aim of this study, which was performed using the Rorschach test, was to identify areas of particular problems in a group of CF adolescents monitored by the Pneumology Division of Regina Margherita Children's Hospital in Turin: 26 subjects aged between 14 and 18, including 11 females and 15 males. METHODS The analysis of the test was based on the use of thought, interior resources, instincts and interpersonal relations. The type of intimate resonance was also taken into account and, lastly, a study of the contents was performed using a self-representation grid. RESULTS The results obtained show a dishomogeneous profile of the development and quality of intellectual processes faced with the intensity of anxiety, mainly loss anxiety, linked to the disease, even if unrelated to its severity. The integration of emotive and instinctual aspects is difficult: mental development towards adult life appears to be impeded by the predominance of regressive modalities. CONCLUSIONS On the basis of the study performed, it is possible to hypothesise the need for psychological help aimed at achieving a more evolved psychic organisation, possible as part of an overall management programme by the medical and nursing team.

Abstract
BACKGROUND AND AIMS The recent positive evolution in the development of cystic fibrosis, resulting in the current prospect of survival, has led to the formation of a new population of chronic patients. The characteristics of the disease and treatment (hereditary, early onset, affecting the alimentary tract and airways) may interfere with personality structuring processes. The aim of the study was to identify the psychopathological risk. METHODS The study was performed using the Rorschach test in a population of children with cystic fibrosis monitored by the Pneumology Division of the Ospedale Infantile Regina Margherita in Turin: 20 children aged between 7 and 13 years old were included in the study, most of whom had been diagnosed before the age of 2. The analysis of tests was focused on the use of thought, interior resources, instincts and interpersonal relations. A study of the contents was also made using a self-representational grid. RESULTS The results obtained highlight an inhibitory attitude which cannot be attributed to intellectual insufficiency, but rather to the failed attempt to invest in the intellectual sphere, typical of this age range, owing to the intensity of anguish. Children with cystic fibrosis appear to be at an earlier stage of development, marked by emotive coarctation and the use of adult-type defensive methods, tending towards rationalisation. CONCLUSIONS Oh the basis of this study, it is possible to detect a danger of disharmonious organisation in the personality structuring process of these children. The hospital must therefore offer adequate psychological support for their psychic evolution.

Abstract
Enteral nutrition is increasingly used in the management of sick children. Malnutrition may frequently complicate chronic illness in children and nutritional support may be a primary treatment. Particularly children with malnutrition due to certain chronic disorders may need long term enteral nutrition not only in hospital but also at home. We report our experience on home enteral nutrition of 14 patients, aged from 3 months to 15 years. Eleven had a serious weight deficit (< 3 degrees percentile), but none had severe alteration of the biohumoral nutritional parameters. The indication for EN were: in 7 patients cerebral palsy, in 2 cystic fibrosis, and in the other 5 patients congenital heart disease, multiple food intolerance, oesophageal athresia, Werding-Hoffman disease, Costello's Syndrome. Nutritional support was given by nasogastric tube in 6 patients, through gastrostomy in 3 patients and by mouth in 5 patients. We did not see any severe complication due to home enteral nutrition. The practicalities of this nutritional approach are discussed. Although home enteral nutrition was evaluated in a low number of patients, it may have a role in promoting growth of children with inadequate dietary intake or malnutrition and in improving their quality of life.

Abstract
Cystic fibrosis (CF) is the most common lethal autosomal recessive disorder among Caucasians, occurring with a frequency of 1/2000 newborn babies. This editorial will consider the clinical features of CF as well as the genomic structure of the CFTR gene and the functional properties of its product, mutations of the gene, correlations between genotypes and phenotypes, strategies for carrier screening, and recent advances in gene therapy. After isolation and cloning of the CFTR gene, different laboratories have characterized over 350 mutations responsible for CF, the most frequent being the delta F508 which accounts for 70% of all CF chromosomes. Studies on correlations between genotypes and phenotypes have confirmed that patients with the homozygous delta F508/delta F508 genotype are severely affected, with major involvement of pancreatic function. Patients with the delta F508/R117H genotype, on the other hand, evidence a mild phenotype with pancreatic sufficiency. Several pilot studies for carrier detection are now in progress. As recent experiments with somatic gene therapy, performed on knock-out mice for the CFTR gene have given satisfactory results, it is hoped that the same approach can soon be used for humans.

Abstract
The authors consider the different strategies in long term enzyme replacement therapy in relation to the complex mechanics at the basis of pancreas exocrine insufficiency. This condition occurs in chronic pancreatitis and is present in Cystic Fibrosis, the most common potentially lethal inherited disorder of Caucasians. Pancreatic exocrine insufficiency occurs in the vast majority of cystic fibrosis affected children and is now becoming a frequent pathology in adults for the better life expectancy and the recent acknowledgements in this disease. The principal aims of research in enzyme replacement therapy have been directed at the formulation of products with high enzyme concentration, to the prevention of gastric acid inactivation of enzymes and to the better mixing of the preparations with meals. The authors consider all the different enzyme preparations from pancreatin powder to the 1st. generation of enteric coated tablets and examine the advantages of administering H-2 receptor antagonists or antacids and the possibility of stimulating bicarbonate secretion as an adjunct to pancreatic enzyme replacement therapy. Significant benefits in pancreatic insufficiency therapy have derived from the introduction of enteric coated microspheres which ensure a consistent level of enzymes to reach the duodenum mixed with the meal and which are resistant to gastric acid inactivation as well.

Abstract
In 20 Italian families with cystic fibrosis (CF), restriction fragment length polymorphisms were detected by five linked markers; a strong linkage disequilibrium is observed between the haplotype B (alleles 2/1 with respect to KM19/XV2c) and CF. The frequency of the delta F508 deletion in CF chromosomes of this sample is 50%. A significant correlation is found between the absence of the delta F508 mutation and pancreatic sufficiency.

Abstract
The purpose of this report is to present an overview on vitamin E distribution, requirements, absorption and biochemical and nutritional aspects. A continuous interest in biochemical functions is recently developed and vitamin E certainly plays an important role throughout the body. The best known of its effects and still actively considered in recent years is the role as an important biological antioxidant. The red blood cell is an ideal model for studying the antioxidant role of vitamin E in cell membranes. Nutritional deprivation is a rare occurrence in developed countries. In prematurely delivered newborns the deficiency is due to marginal stores and to transient malabsorption but it can also be iatrogenic. In infants and adults vitamin E deficiency does occur in syndromes characterized by increased consumption or reduced absorption. Various gastrointestinal disorders induce, with steatorrhoea, marked alteration of vitamin E levels. Cystic fibrosis (CF), the commonest cause of pancreatic insufficiency during the first decades of life, is of particular interest. The fat malabsorption, often severe, may not well respond to pancreatic therapy and the hepatobiliary disease, increased in frequency with improved survival, induce a further reduction in intestinal bile salt concentration. Several manifestations have been attributed to vitamin E deficiency in CF and, although overt neurological complications seem to be relatively uncommon, it is recommended to maintain an adequate supplementation.

Abstract
The irritable bowel syndrome (IBS) is the most common chronic functional gastroenterological disorder both in adults and in children. In this study we evaluate the different aspects of this syndrome, comparing our observations on 332 children with other studies. Epidemiological data (frequency, sex, age) are examined so as the family histories of gastroenterological disorders. We take in account several pathogenic hypotheses, especially with reference to the alterations of gastrointestinal motility, which could be caused by several factors (psychological, prostaglandins, bile acids, etc.). The clinical picture is very variable, variations depending on the age of children and on the time of onset of IBS. The colic of neonate, caused by retention of air, is the main symptom in the first months of life, followed by chronic diarrhoea, also defined as toddler's diarrhoea, sometime alternating with constipation. In later childhood, recurrent abdominal pain represents a common complaint, in association with diarrhoea or constipation. The principal steps for a proper diagnosis so as the main differential diagnosis are defined. We explain the most important features of management (reassuring parents, free diet), excluding prescription of drugs, that produce only a transitory and symptomatic relief, so as elimination diets, that cause only a failure to thrive without any improvement of symptoms.

Abstract
Fasting serum pepsinogen 1 level was determined by radioimmunoassay in 30 patients with cystic fibrosis and in on equal number of age-matched healthy children. Serum pepsinogen 1 basal levels were significantly higher (49 +/- 18 ng/ml; p less than 0.01) in cystic fibrosis patients than in controls (38 +/- 12 ng/ml). The increased pepsinogen 1 level did not correlate with the levels of Po2 and Pco2 tensions, fat balance or basal and maximum acid outputs. It is concluded that the mechanisms which lead to a rise of serum pepsinogen 1 in cystic fibrosis are unknown. However these findings could provide useful information with regard to the biology of a disease whose physiopathology is still unknown.

Abstract
The association of HLA-A,B,C, DR polymorphisms and of Bf and GLO with coeliac disease was analysed in 100 Italian children. Primary involvement of HLA-DR3 and DR7 is apparent, while specificities of nearby loci are probably associated secondarily, because of linkage disequilibrium. Direct assessment of D/DR genotype through family studies and mixed lymphocyte cultures led to the recognition of two high risk genotypes DR3/3 and DR3/7, and of two lower risk genotypes DR3/X and DR7/X. The different weight of the HLA-dependent genetic factors is to some extent correlated with the clinical and immunological parameters, suggesting that the low-risk genotypes induce a milder expression of coeliac disease. Furthermore, other genetic factors, such as sex, appear to contribute to the penetrance of the disease, especially in the case of DR3/X and DR7/X.

Abstract
The replacing therapy in the treatment of pancreatic insufficiency is considered the first and most important step. At present, the choice is between highly concentrate or enteric-coated enzymatic compounds. Their administration before or during each meal has to be the one able to reduce fecal fat and nitrogen, allowing a satisfactory growth. A long term therapy even at low dosage with antacids or cimetidine must be considered with caution and evaluated in each case. In CF children the nutritional care has now been emphasized for the possible relationship between malnutrition and lung disease; the caloric intake must be higher than normal. The limitation of fat intake is not so important any more when the enzymes replacement is adequate. The vitamins requirement is usually satisfied doubling the normal daily requirement. An increase of vitamins and/or minerals must be considered when clinical or laboratory signs of deficiency are found.

Abstract
Serum trypsinlike immunoreactivity (TLI) was measured in 42 children with cystic fibrosis (CF) and related to age and steatorrhea. The mean TLI value in 106 age- and sex-matched control subjects was 22 +/- 7.2 ng/mL. In patients with CF, TLI showed a widespread distribution (range, 0.3 to 214 ng/mL), and an exponential inverse correlation between TLI and age was found. The same trend in the decline in TLI values with increasing age was evident in patients who were followed up. Reduced TLI concentrations were associated with fat malabsorption, but in younger patients with CF, normal or elevated TLI values did not exclude steatorrhea. Elevated serum TLI levels in patients with CF at an early age might reflect pancreatic ductal obstruction. Tendency for TLI to decrease with advancing age and in patients who are followed up can reflect ongoing degenerative destruction within the pancreatic gland. Serum TLI estimation in patients with CF should be used to monitor the progression of pancreatic impairment.

Abstract
During the past ten years 220 pediatric proctosigmoidoscopies with the rigid instrument in 182 infants and children, and 71 colonoscopies in 62, were performed. Advantages and limits of these two instruments are discussed. The indications and results of the different procedures are presented. Positive diagnoses were obtained in 81% with both techniques while the histological examination was positive in 85% of specimens obtained by colonoscopy and only in 51% of the proctosigmoidoscopical ones. Colonoscopy has increasingly became a complementary method for colonic pathology in children, in comparison with adult medicine, however, pediatric indications have been handled mostly with the shorter instrument for two main reasons: 1) Pediatric colonic pathology affects predominantely the lower tract; 2) Neoplastic lesions, in which total colonoscopy with biopies at different levels is mandatory, are extremely rare in children.

Abstract
Little attention has been given to the gastric secretion of pepsin in children. The purpose of this paper is to define the behaviour of peptic concentration (UI/ml) and Basal (BPO) and Stimulated (SPO) Peptic Outputs in children with normal and altered gastric acid secretion. 54 children, aged 15 months to 12 years, were studied: 20 of them were normal, 20 had gastric hypersecretion and 14 were hyposecretors. In the normal subjects the BPO is inversely correlated with age, while the SPO increases with the body weight, but this increment diminishes after the age of 6 years. From these data one can assume that the gastric principal cells reach their functional maturity around the age of 6 years. In the hypersecretors peptic and acid secretions are not correlated in basal conditions, while after pentagrastrin stimulation peptic secretion is greater than in normal subjects but not as the acid one. The SPO is correlated with body weight and height. The different behaviour of hydrochloric acid and pepsin is probably due to the use of pentagrastrin, which is a specific stimulant of oxyntic but not of principal cells. In the hyposecretors both BPO and SPO are lower than in normal children and no correlation was found with age, body weight and acid secretion.

Abstract
A group of 45 children affected with Coeliac Disease (CD) was typed for HLA-A, B, C, D, and DR specificities. The most significant associations were found with two alleles of the D series, with both cellular and serological typing. It is suggested that the susceptibility to CD is determined by two different genes within the HLA region, the first in common with organ-specific autoimmune diseases and associated with DW3, the second possibly specific for CD and associated with Dw7.

Abstract
Of 80 children with proved coeliac disease, 2 presented with an associated disease of the distal portion of the large intestine. In one child the family history and the extension, localisation, and characteristics of intestinal lesions made us suspect ulcerative colitis; in the other we made a diagnosis of milk-induced colitis.

Abstract
The incidence of connective tissue antibodies was assessed in 3,000 adults and in 388 pediatric patients with gastroenterological disorders. Following a previous classification, connective tissue antibodies were distinguished in 5 different types, R1 and R2 reacting with reticulin components, KC with Kupffer cells, AC and Rs with intra- and extracellular mesenchymal antigens. R1 predominated in children and was observed only in patients with malabsorption; the great majority of them had celiac disease and an abnormal small bowel mucosa. Ac was rarely seen in children and occurred in several unrelated gastrointestinal diseases of the adult; its incidence, however, was significantly higher in disorders with idiopathic and secondary malabsorption. R2, KC and Rs were seen only occasionally in unrelated gastroenterological disorders without malabsorption. R1, therefore, seems to be strongly suggestive of a malabsorption syndrome with abnormal small bowel mucosa and AC is a nonspecific reaction occuring predominantly in primary and secondary malabsorption; the other connective tissue antibodies have no clinical significance in gastroenterological disorders.
