Abstract
BACKGROUND Our objective is to present the Peripheral Intravascular Lithotripsy (IVL) System in the treatment of calcific renal artery stenosis (RAS) during Chimney Endovascular Aneurysm Repair (Ch-EVAR). The Ch-EVAR technique is a bail out procedure in treating aortic aneurysms with challenging anatomy regarding the proximal sealing zone. RAS typically involves varying degrees of calcification, and final treatment can be fraught with risk of vessel's damages and suboptimal results, particularly when renal angioplasty represents the only feasible course of action in Ch-EVAR. METHOD We present a case of a patient with a complex juxtarenal abdominal aortic aneurysm and a pre-obstructive chalky stenosis of the right renal artery who underwent mono ChEVAR associated to visceral Intravascular Lithotripsy shockwave angioplasty. CONCLUSION IVL is an attractive modality for the treatment of challenging, heavily calcified renal arteries that combines the calcium-disrupting capability of lithotripsy with the familiarity of balloon catheters to facilitate proper stent deployment. RESULT We propose the IVL system as an additional tool in the vascular surgeon's armamentarium not only to obtain large-bore access to enable Transaortic Valve Replacement (TAVR) and EVAR but also to perform angioplasty of severely calcified visceral arteries during Ch-EVAR.

Abstract
Background This study investigated prevalence and correlates of anemia and uncontrolled anemia in chronic hemodialysis patients. Methods A cross-sectional analysis was performed on registry data for 2,746 chronic (<6 months) hemodialysis patients aged 25–84. Data collection included years of dialysis, hours of dialysis/wk, disease causing hemodialysis, body mass index (BMI), erythropoietin (EPO) treatment, hemoglobin, markers of viral hepatitis, serum albumin, calcium, and phosphorus. Results Prevalence was 88.7% for anemia (hemoglobin <11 g/100 mL and EPO treatment at any Hb level), 39.4% for uncontrolled anemia (hemoglobin<11 g/100 mL). Gender, years of dialysis, hereditary cystic kidney disease (HCKD), and low BMI (<24 kg/m2) were independent correlates of anemia (P<0.001). Gender, HCKD, low BMI, serum albumin and calcium were independent correlates of uncontrolled anemia (P<0.05). An interaction was found between age (not correlated with anemia and uncontrolled anemia) and the association of gender with uncontrolled anemia (P<0.05). EPO doses were higher in patients with high prevalence of uncontrolled anemia than in patients with low prevalence (i.e., women vs men, other diseases vs HCKD, low vs not-low BMI, P<0.01). Gender, years of dialysis, HCKD, BMI, serum albumin, and calcium were independent correlates of the hemoglobin/EPO dose ratio in patients on EPO treatment (P<0.05). Conclusion Anemia and uncontrolled anemia are more frequent in hemodialysis patients with short-term dialysis, diseases other than HCKD, low BMI, and female gender. Gender effect was lower in elderly patients. Uncontrolled anemia was also associated with low serum albumin and calcium, suggesting that these parameters are indices of EPO resistance.

Abstract
Women with bulimia nervosa (BN) frequently have co-occurring alcohol use disorders (AUDs). Studies of shared genetic transmission of these disorders have been mixed. Personality heterogeneity among individuals with BN may explain discrepant findings. Cluster analysis has characterized women with BN in groups on the basis of personality profiles. One group, the Dysregulated cluster, characterized largely by behavioural disinhibition and emotional dysregulation may be more closely linked etiologically to AUDs. This study examined whether genetic associations between BN and AUDs are the strongest among the Dysregulated cluster. Symptoms of BN and AUDs were assessed in female twins at ages 17 and 25 years from the Minnesota Twin Family Study. Personality clusters were defined using the Multidimensional Personality Questionnaire. Twin moderation models suggested small-to-moderate common genetic transmission between BN and AUDs. However, shared genetic effects did not differ by personality cluster. Findings suggest that personality clusters are unlikely to account for inconsistent findings regarding their shared aetiology.

Abstract
Analogously to a spin glass, a large-scale signed social network is characterized by the presence of disorder, expressed in this context (and in the social network literature) by the concept of structural balance. If, as we have recently shown, the signed social networks currently available have a limited amount of true disorder (or frustration), it is also interesting to investigate how this frustration is organized, by exploring the landscape of near-optimal structural balance. What we obtain in this paper is that while one of the networks analyzed shows a unique valley of minima, and a funneled landscape that gradually and smoothly worsens as we move away from the optimum, another network shows instead several distinct valleys of optimal or near-optimal structural balance, separated by energy barriers determined by internally balanced subcommunities of users, a phenomenon similar to the replica-symmetry breaking of spin glasses. Multiple, essentially isoenergetic, arrangements of these communities are possible. Passing from one valley to another requires one to destroy the internal arrangement of these balanced subcommunities and then to reform it again. It is essentially this process of breaking the internal balance of the subcommunities which gives rise to the energy barriers.

Abstract
BACKGROUND Lymphoid aggregates are normally found throughout the small and large intestine. Known as lymphoid nodular hyperplasia (LNH), these aggregates are observed especially in young children and are not associated with clinical symptoms being considered 'physiological'. In children presenting with gastrointestinal symptoms the number and size of the lymphoid follicles are increased. Patients suffering from gastrointestinal symptoms (i.e. recurrent abdominal pain) should systematically undergo gastroduodenoscopy and colonoscopy. With these indications LNH, especially of the upper but also of the lower gastrointestinal tract has been diagnosed, and in some children it may reflect a food hypersensitivity (FH) condition. AIM To review the literature about the relationship between LNH and FH, particularly focusing on the diagnostic work-up for LNH related to FH. METHODS We reviewed literature using Pubmed and Medline, with the search terms 'lymphoid nodular hyperplasia', 'food hypersensitivity', 'food allergy' and 'food intolerance'. We overall examined 10 studies in detail, selecting articles about the prevalence of LNH in FH patients and of FH in LNH patients. RESULTS Collected data showed a median of 49% (range 32-67%) LNH in FH patients and a median of 66% (range 42-90%) FH in LNH patients. Literature review pointed out that the most important symptom connected with LNH and/or FH was recurrent abdominal pain, followed by diarrhoea and growth retardation. Both LNH and FH are associated with an increase in lamina propria γ/δ+ T cells, but the mechanisms by which enhanced local immune responses causing gastrointestinal symptoms still remain obscure. CONCLUSIONS When assessing FH, we rely on clinical evaluation, including elimination diet and challenge tests, and endoscopic and immunohistochemical findings. Considering the possible co-existence of duodenal and ileo-colonic LNH, upper endoscopy can be recommended in children with suspected FH, especially in those presenting with additional upper abdominal symptoms (i.e. vomiting). Likewise, lower endoscopy might be additionally performed in patients with suspected FH and LNH of the duodenal bulb, also presenting with lower abdominal symptoms (i.e. recurrent abdominal pain).

Abstract
PURPOSE To evaluate the usefulness of abdominal ultrasound examination (US) for the diagnostic workup of cases of suspected CD involving negative serum antibodies and difficult diagnosis. MATERIALS AND METHODS 524 consecutive patients with symptoms of suspected CD underwent an extensive diagnostic workup. 76 (14 %) were excluded since they were positive for serum anti-tTG and/or EmA antibodies. 377 were excluded since they were diagnosed with something other than CD or did not have the alleles encoding for HLA DQ 2 or DQ 8. A diagnosis of CD with negative serum antibodies was probable in 71 patients who underwent abdominal US and duodenal biopsy for histology evaluation. RESULTS Intestinal histology and subsequent clinical and histological follow-up confirmed the CD diagnosis in 12 patients (GROUP 1) and excluded it in 59 subjects (GROUP 2). Abdominal US showed that the presence of dilated bowel loops and a thickened small bowel wall had a sensitivity of 83 % and a negative predictive value (NPV) of 95 % in CD diagnosis. Furthermore, in 11 of the 12 CD seronegative patients there was at least one of these two abdominal US signs. Therefore, considering the presence of one of these two signs, abdominal US sensitivity increased to 92 % and NPV to 98 %. CONCLUSION Abdominal US is useful in the diagnostic workup of patients with a high clinical suspicion of CD but with negative serology.

Abstract
In 2009 and 2010, approximately 2% of plants had disease symptoms, including initial leaflet chlorosis that later developed into necrotic spots and general necroses along the leaflet. Fruit production on affected plants was substantially reduced and necroses were also present. Total RNA was extracted from five symptomatic plant samples using the RNeasy Plant Mini Kit (Qiagen, Hilden, Germany) and analyzed by reverse transcription (RT)-PCR with specific primer pair: TR2F (5' GAAGGACGAAGAGCGACTG 3'), and TR2R (5' AAGGTAGGTATGCGTTTGC 3') (1). The primers amplified a 575-bp fragment within the coat protein Vp23 of Tomato torrado virus (ToTV). No RT-PCR products were observed when water or asymptomatic tomato plants were used as controls. The RT-PCR products were purified and directly sequenced in both directions. Pair-wise similarity analysis confirmed the presence of ToTV with 99% similarity to isolate PRI-ToTV0301 (GenBank Accession No. DQ388880) and 98% similarity to isolate Kra (Accession No. EU652402). A representative sequence was deposited with GenBank (Accession No. GU903899). To further confirm the presence of ToTV, dsRNA analysis was conducted on all five symptomatic plants and one healthy tomato plant (2). Electrophoresis of dsRNA showed two bands of approximately 5,400 and 7,800 nucleotides long, typical of ToTV in all samples, while a third band between the other two (approximately 6,400 nt) was detected. Serological testing using double-antibody sandwich-ELISA was also conducted on the five symptomatic and 25 additional plants from the same greenhouse that displayed typical Pepino mosaic virus (PepMV) symptoms only. Antibodies used for serological testing screened for the presence of PepMV, Tomato spotted wilt virus, Cucumber mosaic virus, and Tomato mosaic virus (Loewe Biochemica, Sauerlach, Germany). These tests detected PepMV in all samples with disease symptoms typical of PepMV, and in three of the five samples with the newly described symptoms. To our knowledge, this is the first report of ToTV in Italy, and in some plants, co-infection with PepMV was likely. All ToTV-infected tomato plants in the greenhouse were destroyed.

Abstract
The authors use ideas from graph theory in order to determine how distant is a given biological network from being monotone. On the signed graph representing the system, the minimal number of sign inconsistencies (i.e. the distance to monotonicity) is shown to be equal to the minimal number of fundamental cycles having a negative sign. Suitable operations aiming at computing such a number are also proposed and shown to outperform all algorithms that are so far existing for this task. [Includes supplementary material].

Abstract
INTRODUCTION The ICH S7A and S7B guidelines require that effects of test substances on the cardiovascular system be assessed with respect to blood pressure, heart rate and electrocardiogram intervals. Where adverse effects are identified additional supplemental studies, including ventricular contractility, should be conducted as deemed appropriate. However, there is an absence of definitive guidance regarding when to pursue supplementary studies, in part due to ill-defined criteria of what constitutes an adverse effect and to surgical/technical monitoring limitations of study designs. However with advances in technology it is now feasible to develop models for assessing LVP and contractility in conjunction with standard assessments. The objectives of this study were to 1) develop a model for chronic evaluation of LVP and contractility, 2) illustrate changes in LV contractility without concurrent proportional changes in heart rate and/or systemic blood pressure and 3) determine if the QA interval, the time between the Q on the ECG and the beginning of the upstroke on the arterial blood pressure, can be used as a indicator of altered LV contractility. METHODS Dogs (N=4) were implanted with a telemetry transmitter. LVP, contractility, ECG and BP were assessed prior to and up to 24 h following administration of Atenolol (10 mg/kg) and Pimobendan (0.45 mg/kg). RESULTS Atenolol caused an approximately 30% decrease in HR, followed by a sustained decrease in maximum left ventricular contractility (+dP/dt mmHg/s). No effects were noted on blood pressure. Pimobendan caused a 100% increase in contractility (+dP/dt mmHg/s) which remained elevated for approximately 4 h. No effects were noted on blood pressure. Heart rate was highly variable initial decreasing, followed by a highly variable increase until 4 h postdose. Following administration of both compounds changes in maximum left ventricular contractility correlated with reverse changes in QA interval duration. DISCUSSION This model demonstrates that evaluation of LV contractility complements measurements of heart rate and blood pressure as part of a more complete cardiovascular safety assessment strategy. Furthermore, we demonstrate an apparent correlation between dP/dt and QA interval and concluded that QA interval can be utilized as an indicator of a potential inotropic effect. However further confirmation should be assessed through additional in-vivo measurements of LVP and contractility.

Abstract
AIMS Oral mucosal lesions may be markers of chronic gastrointestinal disorders, such as those causing malabsorption. Our objectives were to assess the prevalence of recurrent oral aphthous-like ulcers in coeliac disease patients living in the Mediterranean area, and to evaluate the impact of a gluten-free diet. METHODS A test group of 269 patients (age range 3-17 years) with coeliac disease confirmed both serologically and histologically was compared with a control group of 575 otherwise clinically healthy subjects for the presence, or a positive history of aphthous-like ulcers. Coeliac disease patients with aphthous-like ulcers were re-evaluated 1-year after starting a gluten-free diet. RESULTS Aphthous-like ulcers were found significantly more frequently in coeliac disease, in 22.7% (61/269) of patients with coeliac disease versus 7.1% (41/575) of controls (p=<0.0001; chi-square=41.687; odds ratio=4.3123; 95% confidence interval=2.7664:6.722). Most coeliac disease patients with aphthous-like ulcers and adhering strictly to gluten-free diet (71.7%; 33/46) reported significant improvement on gluten-free diet, with no or reduced episodes of aphthous-like ulcers (p=0.0003; chi-square=13.101; odds ratio=24.67; 95% confidence interval=2.63:231.441). CONCLUSIONS The epidemiological association found between coeliac disease and aphthous-like ulcers suggests that recurrent aphthous-like ulcers should be considered a risk indicator for coeliac disease, and that gluten-free diet leads to ulcer amelioration.

Abstract
BACKGROUND Many coeliac disease patients with atypical symptoms remain undiagnosed. AIM To examine the frequency of oral lesions in coeliac disease patients and to assess their usefulness in making coeliac disease diagnosis. PATIENTS AND METHODS One hundred and ninety-seven coeliac disease patients and 413 controls were recruited and the oral examination was performed. RESULTS Forty-six out of 197 coeliac disease patients (23%) were found to have enamel defects vs. 9% in controls (P < 0.0001). Clinical delayed eruption was observed in 26% of the pediatric coeliac disease patients vs. 7% of the controls (P < 0.0001). The prevalence of oral soft tissues lesions was 42% in the coeliac disease patients and 2% in controls (P < 0.0001). Recurrent aphthous stomatitis disappeared in 89% of the patients after 1 year of gluten-free diet. Multi-logistic analysis selected the following variables as the most meaningful in coeliac disease patients: dental enamel defects (OR = 2.652 CI = 1.427-4.926) and soft tissue lesions (OR = 41.667, CI = 18.868-90.909). Artificial Neural Networks methodology showed that oral soft tissue lesions have sensitivity = 42%, specificity = 98% and test accuracy = 83% in coeliac disease diagnosis. CONCLUSIONS The overall prevalence of oral soft tissue lesions was higher in coeliac disease patients (42%) than in controls. However, the positive-predictive value of these lesions for coeliac disease diagnosis was low.

Abstract
BACKGROUND Previous studies have demonstrated that serum anti-actin antibodies are a reliable marker of intestinal damage severity in coeliac disease. AIMS To validate in a multicentre study the clinical usefulness of serum IgA anti-actin antibody ELISA and its possible use in monitoring intestinal mucosa lesions during gluten-free diet. PATIENTS AND METHODS Four centres recruited 205 newly diagnosed coeliac disease patients with villous atrophy, 80 healthy controls and 81 "disease" controls. Twelve coeliac disease patients on gluten-free diet but with persistent symptoms underwent serum IgA anti-actin antibody assay and intestinal histology evaluation. IgA anti-actin antibody ELISA was performed with a commercial kit. All coeliac disease patients underwent intestinal histology study. RESULTS IgA anti-actin antibodies showed a sensitivity of 80% and a specificity of 85% in the diagnosis of coeliac disease patients with villous atrophy. The area under the receiving operator curve for anti-actin antibodies was 0.873 [95% C.I. 0.805-0.899]. Serum anti-actin antibodies values were significantly higher in coeliac disease patients than in healthy or "disease" controls (P<0.0001). Serum anti-actin antibodies were positive in 41 of the 60 coeliac disease patients with mild intestinal histology lesions (69%) and in 123 of the 145 with severe lesions (85.3%) (P<0.05). There was a significant inverse correlation between anti-actin antibody values and the villi/crypts ratio (r=-0.423; P<0.0001). In the 12 coeliac disease patients on gluten-free diet who underwent re-evaluation as they were persistently symptomatic, intestinal histology showed three cases with persistent villous atrophy: all of these were positive for serum anti-actin antibodies ELISA, whereas both serum anti-tTG and EmAs were negative. The other nine patients showed normal intestinal villi and were negative for serum anti-actin antibodies. CONCLUSIONS Anti-actin antibodies are a reliable marker of severe intestinal mucosa damage in coeliac disease patients and a simple ELISA technique offers an accurate method for their determination. These antibodies seem to be a very reliable marker of persistent intestinal damage in coeliac disease patients.

Abstract
BACKGROUND Antiendomysial (EmA) and antitransglutaminase (anti-tTG) antibodies are the most specific indirect marker of coeliac disease (CD). It is not known whether the oral mucosa of patients with CD is able to produce these antibodies or not. AIMS To evaluate the ability of the oral mucosa of patients with CD to produce antibodies in an in vitro culture system. PATIENTS AND METHODS Twenty-eight patients with new diagnosis of CD (15 adults and 13 children) and 14 adult subjects with other diseases (controls) were studied. All underwent oral mucosa biopsy and subsequent EmA and anti-tTG assays on the mucosa culture medium. RESULTS Sensitivity and specificity of EmA and anti-tTG assayed in the oral mucosa culture medium for CD diagnosis were 54% and 100% and 57% and 100%, respectively. The CD clinical presentation, such as the presence of oral mucosa lesions, did not influence the results of the EmA and anti-tTG assays in the oral mucosa culture medium. There was an association between positivity of antibodies and greater severity of the oral mucosa lymphocyte infiltration. CONCLUSION This study demonstrates that the oral mucosa contributes to EmA and anti-tTG production in untreated patients with CD.

Abstract
BACKGROUND Chronic constipation is common in the general population. Some studies have shown that in children cow's milk protein hypersensitivity can cause chronic constipation unresponsive to laxative treatment. AIMS To review the literature and summarize the data that point to a relationship between refractory chronic constipation and food hypersensitivity, and to discuss the hypothesis that the pathogenesis of constipation due to food hypersensitivity. METHODS A search in the U.S. National Library of Medicine was performed, matching the key words 'chronic constipation, food intolerance and allergy'. RESULTS Thirty-three papers were found but only 19 of them were related to the topic of this review. Most of the data indicated a relationship between constipation and food allergy in a subgroup of paediatric patients with 'idiopathic' constipation unresponsive to laxative treatment. There was only one study in adults that demonstrated the resolution of chronic constipation on hypoallergenic diet in four patients. CONCLUSIONS An increasing number of reports suggest a relationship between refractory chronic constipation and food allergy in children. Similar data in adults are scarce and need to be confirmed. Further studies should be performed to obtain firmer evidence for the role of allergy in constipation and clarify the pathogenetic mechanisms involved.

Abstract
Coeliac disease, daily more frequently diagnosed in our population, involves many organs also in oligosymptomatic patients and with an adequate nutritional regime. Possible endocrine implications include failure to thrive, pubertal delay and reproduction diseases due to deregulation of GH, FSH and LH secretion. Leptin, an adipose tissue hormone, can be decreased as well and its deficiency could be related to growth and puberty anomalies. We studied 14 asymptomatic coeliac patients in peripubertal age (7.5-13.8 years) and tested their leptin levels in order to correlate them with endocrine and anthropometric data. Before the diet was started leptinaemia (M+/-DS) was: 4.94+/-5.53 ng/ml. In 10/14 patients (71%) leptinaemia was<or=2 DS for gender and age. In all the patients, after a period of 6-12 months of gluten-free diet, Leptin levels appreciably raised to 10.8+/-7.9 ng/ml, with a significant correlation to the time of the diet. Leptinaemia was actually lower in patients with a severe mucosal atrophy, and in these patients it increased more significantly after the diet was started. The removal of gluten itself may reduce immunological hit to adipose tissue and the 'malnutrition' of adipocytes: leptin can hence increase despite no significant increase of body mass index occurs. This study could partially explain the correlation between body mass index, Coeliac disease and the deregulation of puberty and fertility, mainly in patients who started the diet late. It could also explain the reversibility of this alteration if the cause is removed.

Abstract
BACKGROUND Sevelamer hydrochloride, a major phosphate binder for patients on maintenance hemodialysis (MHD) is associated with reduced serum bicarbonate concentration due to hydrochloric acid release in the gut and to the binding of short chain fatty acids in the large intestine. Since metabolic acidosis can be deleterious, a study was devised to compare the time course of serum bicarbonate concentration during treatment with sevelamer hydrochloride or calcium carbonate. METHODS Sixteen well nourished patients on MHD who were in excellent clinical conditions and achieving target levels for blood pressure (BP) and hemoglobin (Hb), while on a protein intake of 1.1g/kg body weight (bw), were enrolled in the study. After a 2-week washout period, the patients were divided into two groups, each consisting of eight patients, and randomized either to 24 weeks of sevelamer followed by 24 weeks of calcium carbonate (group A) or to 24 weeks of calcium carbonate followed by 24 weeks of sevelamer (group B). Protein intake, n-protein catabolic rate (nPCR), serum concentrations of calcium, phosphate, calcium x phosphate (Ca x P) product, bicarbonate, intact parathyroid hormone (iPTH) and albumin were monitored. Time course changes in serum bicarbonate concentrations in relation to short and long dialytic intervals (48 vs. 72 hr) were also investigated. RESULTS Both sevelamer and calcium carbonate effectively controlled serum phosphate and the Ca x P product. During calcium carbonate treatment plasma phosphate concentrations were significantly below those of patients on sevelamer. Plasma bicarbonate concentration fell within target DOQI values during calcium carbonate administration both in group A and in group B, a goal which was not achieved under sevelamer administration. After a long dialytic interval in patients on sevelamer, serum bicarbonate concentration averaged 17.3 +/- 1.1 mEq/L, whereas it averaged 21.1 +/- 0.7 mEq/L in patients on calcium carbonate (p<0.01). Finally, a 24-week sevelamer administration caused a statistically significant (p<0.05) reduction (0.8 g/dL) in serum albumin concentration, without affecting iPTH. Taken together, these results indicate that sevelamer worsens metabolic acidosis, which needs to be corrected.

Abstract
OBJECTIVE To evaluate frequency, causes and results of conversion to Open repair (OR) after endovascular repair (EVAR) in a single centre during an 8-year period. DESIGN Six hundred and forty-nine consecutive patients undergoing EVAR were followed up prospectively for endograft-related complications. OUTCOMES Early conversion was any OR during or within 30 days from the primary EVAR. Late conversion was any OR with removal of the endograft after 30 days since a completed EVAR procedure. RESULTS Median patient follow-up was 38 months (1-93 months). Conversion to OR was performed in 38 patients; nine early and 29 late. Most (7/9) early conversions were due to extensive vessel calcification. Peri-operative mortality was 22% (2/9). Late conversions occurred at a median of 33 months after primary EVAR: 29 were elective and 4 urgent. During the same interval, 79 secondary endovascular interventions were performed, 7 of which failed. The risk of conversion to OR was 9% at 6 years. At multivariate logistic regression analysis, no single factor (short, large or angulated neck, suprarenal fixation, large pre-operative diameter, iliac aneurysms, ASA score risk) was associated with the risk of late failure requiring conversion to OR. CONCLUSION The risk of death after early conversion should be recognized, to avoid forcing morphological indications for primary EVAR. Occurrence of late conversion after EVAR is not negligible, affecting almost 1 out of 10 patients after 6 years. In the presence of an expanding aneurysm after EVAR, especially after a failed secondary endovascular correction, an aggressive attitude in fit patients allows outcomes at similar to those of primary OR.

Abstract
BACKGROUND During the first months of life, infants can suffer from many 'minor' gastroenterological disturbances. However, little is known about the frequency of these problems and the factors which predispose or facilitate their onset. AIMS (a) To ascertain the frequency of the most common gastrointestinal symptoms in infants during the first 6 months after birth; (b) to evaluate the influence of some variables on the onset of the symptoms. STUDY DESIGN AND PATIENTS Each of the 150 paediatricians distributed throughout Italy followed 20 consecutive infants from birth to 6 months. 2879 infants (1422 f, 1457 m) concluded the study. The presence of the following symptoms was evaluated: constipation, diarrhoea, vomiting, regurgitation, failure to thrive and prolonged crying fits (colic). Symptoms were recorded whenever the parents requested a clinical check-up or during a set monthly examination. RESULTS 1582/2879 (54.9%) infants suffered from one of the gastrointestinal symptoms. Regurgitation was the most common disturbance (present in 23.1% of infants), followed by colic (20.5%), constipation (17.6%), failure to thrive (15.2%), vomiting (6%) and diarrhoea (4.1%). Low birth weight was the factor most frequently associated with the onset of gastrointestinal symptoms, followed by low gestational age. Feeding habits did not influence the onset of symptoms, with the exception of constipation, which was linked to a low frequency of breast-feeding. Ninety-three infants (3.2%) were hospitalised for one or more of the gastrointestinal symptoms which were considered. During the whole study period the type of formula-milk was changed in 60% of the infants with one or more gastrointestinal symptoms, and in 15.5% of the infants who did not suffer from any gastrointestinal troubles. CONCLUSIONS Gastrointestinal symptoms are very common in infants during the first 6 months after birth. These symptoms required hospitalisation only in a small percentage of cases, but led to the prescription of a 'dietary' milk formula in approximately 60% of the cases. Low birth weight and low gestational age were the main factors influencing the onset of the symptoms.

Abstract
BACKGROUND Although anti-endomysial antibodies (EmA) have been found in the supernatants of cultured intestinal mucosa from patients with coeliac disease (CD), in no study has the clinical reliability of this new diagnostic tool been investigated. Our aims were to evaluate the clinical usefulness of the in vitro production of EmA in CD diagnosis in consecutive patients with suspected CD, and to evaluate the reliability of the in vitro challenge in CD patients on a gluten-free diet (GFD). METHODS For the former aim, consecutive patients who were due to undergo intestinal biopsy for suspected diagnosis of CD were enrolled: according to the final diagnosis, these patients were divided into two groups: Group 1 comprised 91 newly diagnosed CD patients (40 males; age range 7 months to 84 years), Group 2 included 100 subjects with diseases other than CD (44 males; age range 9 months to 76 years). For the latter aim, we also studied 21 CD patients on a gluten-free diet after 16-123 months (8 males; age range 3-51 years), with normal intestinal architecture (Group 3) and 22 patients who served as controls (12 males; age range 4-60 years) with gastroesophageal reflux disease-like symptoms (Group 4). All patients underwent determination of serum anti-gliadin (AGA) and EmA antibodies, histology evaluation of the intestinal biopsies and EmA assay in the supernatants of in vitro gliadin-challenged duodenal mucosa. RESULTS EmA assay in the supernatants showed a sensitivity and specificity of 96% and 100%, respectively; these were not significantly different from those observed for serum EmA (88% and 99%, respectively). However, EmA assay in the supernatants was useful in CD patients with mild intestinal histology lesions (infiltrative/hyperplastic type): in this subgroup it was positive in 9/12 of cases, but serum EmA was positive in only 2/12. As regards the reliability of the in vitro gliadin challenge, EmA production in supernatants was recorded only in 10/21 CD patients on a gluten-free diet. The patients with a positive in vitro challenge had a higher number of intra-epithelial lymphocytes than patients with a negative challenge. CONCLUSIONS 1) EmA assay in the medium of cultured intestinal biopsy can detect gluten-sensitive enteropathy, characterized by an infiltrative/hyperplastic histological pattern, which is often associated with negative serum EmA. 2) The in vitro challenge in CD patients on a gluten-free diet detects EmA production in the culture medium only in half of the cases and other studies must be performed to evaluate whether EmA production after in vitro challenge can be considered a reliable test for confirming CD diagnosis.

Abstract
BACKGROUND It has been suggested that serological screening for coeliac disease (CD) should be performed in patients with chronic unexplained hypertransaminasaemia. AIMS To evaluate the specificity for CD diagnosis of serum IgA antitissue transglutaminase (tTG) determination in consecutive patients with chronic hypertransaminasaemia using the most widely utilised ELISA based on tTG from guinea pig as the antigen. PATIENTS AND METHODS We studied 98 patients with chronic hypertransaminasaemia, evaluated for the first time in a hepatology clinic. Serum anti-tTG and antiendomysial (EmA) assays were performed. Patients positive for EmA and/or anti-tTG were proposed for intestinal biopsy. Finally, all sera were reassayed for anti-tTG using an ELISA based on human recombinant tTG as the antigen. RESULTS A total of 94/98 hypertransaminasaemic patients were positive for hepatitis virus markers, with 82/98 (83%) positive for anti-hepatitis C virus. Liver histology showed that most patients had mild or moderate chronic hepatitis while severe fibrosis or overt liver cirrhosis was found in 20/98. CD screening showed that 15/98 (16%) hypertransaminasaemic subjects had anti-tTG values in the same range as CD patients; however, IgA EmA were positive in only 2/98 (2%). Distal duodenal biopsy, performed in nine patients, showed subtotal villous atrophy in the two EmA+/anti-tTG+ patients but was normal in 7/7 EmA-/anti-tTG+ subjects. The presence of anti-tTG+ values in EmA- patients was unrelated to particular gastrointestinal symptoms, other associated diseases, severity of liver histology, or distribution of viral hepatitis markers. There was a significantly higher frequency of positive serum autoantibodies (antinuclear, antimitochondrial, antismooth muscle, and anti-liver-kidney microsomal antibodies) in anti-tTG+/EmA- patients than in the other subjects (9/13 v 10/83; p<0.003). Also, a correlation was found between serum gamma globulin and anti-tTG values (p<0.01). When sera were tested with the ELISA based on human tTG as the antigen, no false positive results were observed: only the two EmA+ patients with atrophy of the intestinal mucosa were positive for anti-tTG while all others were negative, including those false positive in the ELISA based on guinea pig tTG as the antigen. CONCLUSIONS In patients with elevated transaminases and chronic liver disease there was a high frequency of false positive anti-tTG results using the ELISA based on tTG from guinea pig as the antigen. Indeed, the presence of anti-tTG did not correlate with the presence of EmA or CD. These false positives depend on the presence of hepatic proteins in the commercial tTG obtained from guinea pig liver and disappear when human tTG is used as the antigen in the ELISA system. We suggest that the commonly used tTG ELISA based on guinea pig antigen should not be used as a screening tool for CD in patients with chronic liver disease.

Abstract
In patients with coeliac disease, a regression of intestinal damage without a gluten-free diet is a very rare event. We describe a young child with diarrhoea, intestinal mucosa atrophy and positive serum anti-endomysial and anti-tissue transglutaminase (anti-tTG) antibodies during intestinal giardiasis infection. He showed normal intestinal mucosa architecture and negative anti-endomysial and anti-tTG antibodies after his giardiasis was cured, although he continued to assume a normal diet. Re-evaluations on a 6-monthly basis showed that he was symptom free, and all haemato-chemical parameters were within normal limits. Three years after the initial diagnosis, a third intestinal biopsy showed: normal mucosa architecture; an increase in the intra-epithelial CD3+ and gamma/delta+ lymphocyte counts; and immunoglobulin-A anti-endomysial antibody detection in the supernatant of the intestinal mucosa culture incubated with gliadin. An active coeliac disease status, with intestinal mucosa atrophy, may regress to a latent coeliac disease status with normal intestinal mucosa histology after removal of the environmental factors that have presumably precipitated mucosa damage. Serum anti-endomysial and anti-tTG antibody behaviour is not a permanent, life-long feature and this must recommend the repetition of anti-endomysial or anti-tTG antibody assays in the same patient whenever coeliac disease diagnosis is again suspected, irrespective of previous negativity.

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 Childhood gastroenteritis is associated with considerable health costs. The natural clay dioctahedral smectite increases intestinal barrier function and is effective against infectious diarrhea in children in developing countries. The purpose of this work was to investigate the efficacy of smectite in Italian children with acute diarrhea of mild to moderate severity. METHODS A national, prospective, randomized, case-controlled study was performed in collaboration with primary care pediatricians. Children seen by pediatricians for acute gastroenteritis were treated with oral rehydration solution (ORS) alone or ORS with smectite. Parents returned a form in which total duration of diarrhea, incidence of vomiting and fever, persistence of diarrhea for more than 7 days and hospital admissions were recorded. RESULTS Eight hundred four children with acute diarrhea were randomly assigned to treated or control groups. Administration of smectite was associated with significant reduction of the duration of diarrhea, as judged by stool frequency and consistency. The incidence and duration of vomiting and fever were not different. Diarrhea lasted more than 7 days in 10% of treated and in 18% of control children (P < 0.01). Hospital admission was necessary in seven treated and six control children. No side effects were observed. CONCLUSIONS Smectite reduces the duration of diarrhea and prevents a prolonged course. It may therefore consistently reduce the costs of gastroenteritis.

Abstract
Coeliac disease (CD) is a malabsorptive disorder of the small intestine resulting from ingestion of gluten. The HLA risk factors involved in CD are well known but do not explain the whole genetic susceptibility. Several regions of potential linkage on chromosomes 3q, 5q, 10q, 11q, 15q and 19q have already been reported in the literature. These six regions were analyzed with the Maximum Lod Score method on a dense set of markers. A new sample of 89 Italian sibpairs was available for study. There was no evidence for linkage for any of the regions tested, except for chromosome 5q. For this region, our data, as well as a sample of 93 sibpairs from our first genome screen (Greco et al. 1998), are compatible with the presence of a risk factor for CD with a moderate effect.

Abstract
BACKGROUND Multiple food intolerance in infants, including intolerance to extensively hydrolysed proteins (HP), is often difficult to treat. However, few data have been reported on clinical outcome and dietary treatment of these patients. AIMS To evaluate the clinical characteristics of patients with HP-intolerance and the long-term outcome of treatment with ass' milk. PATIENTS AND METHODS This study included 21 HP-intolerant infants (15 males, median age at diagnosis 2 months) treated with an ass' milk-based diet and 70 cow's milk (CM) intolerant infants (40 males, median age at diagnosis 3 months) treated with casein hydrolysate milk-based diet. All patients were followed-up for a median period of 4 years. Both HP-intolerance and intolerance to other foods were diagnosed according to the double-blind placebo-controlled procedure. Formal CM-challenges were conducted at yearly intervals until tolerance was demonstrated. At diagnosis and after one year of the respective diets, the following growth parameters were determined: relative weight for sex and age, relative weight for height and height z-score. RESULTS During the study period, multiple food intolerance was documented in 21/21 HP-intolerant infants (ass' milk group) and in 20/70 infants with CM-intolerance but tolerating HP (casein hydrolysate group) (P < 0.0001). In the ass' milk group, the more frequent food intolerances were toward soya, oranges, tomatoes and fish; goat's milk intolerance was demonstrated in five out of six patients receiving this food, and sheep's milk derivatives intolerance in four out of seven; these patients tolerated ass' milk. During the study period 3/21 patients in the ass' milk group became ass' milk intolerant; they showed vomiting (one cases) or diarrhoea (two cases). A lower percentage (52%) of patients in the ass' milk group became CM-tolerant during the study period than in the casein hydrolysate group (78%) (P < 0.01) and the age of the children at CM-tolerance was higher in the ass' milk than in the casein hydrolysate-treated children (P < 0.05). At diagnosis, a higher frequency of cases with elevated serum total IgE and specific IgE to CM antigens (P < 0.01) was observed in the ass' milk group. No difference was recorded between the two treatment groups in any of the growth parameters considered either at diagnosis or during the follow-up. CONCLUSIONS HP-intolerant patients showed a higher frequency of persistent food intolerance and of multiple food intolerance than patients tolerating casein hydrolysate. Ass' milk feeding was confirmed as a safe and valid treatment of the most complicated cases of multiple food intolerance.

Abstract
BACKGROUND In patients with cow's milk protein intolerance (CMPI), delayed clinical reactions to cow's milk (CM) ingestion may be misdiagnosed if the clinical symptoms are not "classical" and there is a long time lapse between ingestion of CM and the clinical reaction. The aim was to evaluate the clinical outcome of CMPI in a cohort of CM-intolerant children, with particular attention to the occurrence of clinical manifestations beyond 72 h after CM challenge. METHODS Eighty-six consecutive patients (44 boys, 42 girls) with new CMPI diagnoses were enrolled; median age at diagnosis was 4 months. Patients were followed up for a mean period of 40 months. In all patients, CMPI diagnosis was made on the observation of symptoms, their disappearance after elimination diet, and their reappearance on double-blind CM challenge. At CMPI diagnosis, immunologic tests to demonstrate IgE-mediated hypersensitivity were performed. After 12 months of CM-free diet, CM tolerance was re-evaluated with a CM challenge continued at home for up to 30 days, according to a double-blind, placebo-controlled method. Patients who did not achieve CM tolerance continued a CM-free diet and subsequently underwent yearly CM challenge. RESULTS The percentages of CMPI patients who became CM-tolerant after 1, 2, and 3 years of CM-free diet were 30%, 54.5%, and 70%, respectively. At the end of the follow-up period, 26/86 subjects showed persistent CMPI; these patients had a higher percentage of positivity of total serum IgE (P<0.05), RAST (P<0.01), and cutaneous prick tests for CM antigens (P<0.001) than all the others. At CMPI diagnosis, all patients had a clinical reaction within 72 h from the beginning of the CM challenge; at the subsequent "cure" challenges, we observed patients who first reacted to CM more than 72 h after ingestion. In total, 10 out of 86 patients showed "very delayed reactions"; in these patients, the mean time between the beginning of CM challenge and the onset of a clinical symptom was 13.3 days (range 4-26 days). The number of "very late reactors" increased from the first to the third of the "cure" CM challenges, performed at yearly intervals. The "very delayed" CMPI manifestations in these subjects were constipation (five cases), wheezing (two cases), dermatitis plus constipation (two cases), and dermatitis alone (one case); in 6/10 patients, the symptoms observed at the "cure challenge" were different from those at CMPI onset. CONCLUSIONS Very delayed clinical reactions to reintroduction of CM in the diet can occur in CMPI patients; thus, accurate follow-up and frequent outpatient observation in patients with a long history of CMPI are probably more useful and safer than prolonged CM challenge.

Abstract
Cow's milk allergy (CMA) and gastroesophageal reflux are considered to be among the most common disturbances in infants less than 1 year of age. In recent years, the relationship existing between these two entities has been investigated and some important conclusions have been reached: In just under half the cases of GER in infants less than 1 year of age there is an association with CMA; in a high proportion of cases, GER is not only CMA-associated but also CMA-induced; the frequency of this association should induce pediatricians to screen for possible concomitant CMA in all infants with GER less than 1 year old; with the exception of some patients with mild typical CMA manifestations (diarrhea, dermatitis, or rhinitis), the symptoms of GER associated with CMA are the same as those observed in primary GER; immunologic tests are useful in a suspected association between GER and CMA; and subjects with GER secondary to CMA show a typical pH-monitoring tracing pattern, characterized by a progressive, slow decrease in esophageal pH between feedings. This article reviews the main features of the two diseases, stressing the aspects in common between them and comments on all the listed points.

Abstract
BACKGROUND Chronic diarrhea is the most common gastrointestinal symptom of intolerance of cow's milk among children. On the basis of a prior open study, we hypothesized that intolerance of cow's milk can also cause severe perianal lesions with pain on defecation and consequent constipation in young children. METHODS We performed a double-blind, crossover study comparing cow's milk with soy milk in 65 children (age range, 11 to 72 months) with chronic constipation (defined as having one bowel movement every 3 to 15 days). All had been referred to a pediatric gastroenterology clinic and had previously been treated with laxatives without success; 49 had anal fissures and perianal erythema or edema. After 15 days of observation, the patients received cow's milk or soy milk for two weeks. After a one-week washout period, the feedings were reversed. A response was defined as eight or more bowel movements during a treatment period. RESULTS Forty-four of the 65 children (68 percent) had a response while receiving soy milk. Anal fissures and pain with defecation resolved. None of the children who received cow's milk had a response. In all 44 children with a response, the response was confirmed with a double-blind challenge with cow's milk. Children with a response had a higher frequency of coexistent rhinitis, dermatitis, or bronchospasm than those with no response (11 of 44 children vs. 1 of 21, P=0.05); they were also more likely to have anal fissures and erythema or edema at base line (40 of 44 vs. 9 of 21, P<0.001), evidence of inflammation of the rectal mucosa on biopsy (26 of 44 vs. 5 of 21, P=0.008), and signs of hypersensitivity, such as specific IgE antibodies to cow's-milk antigens (31 of 44 vs. 4 of 21, P<0.001). CONCLUSIONS In young children, chronic constipation can be a manifestation of intolerance of cow's milk.

Abstract
BACKGROUND In coeliac disease it has been demonstrated that the indirect pancreatic function tests detect a greater percentage of subjects with exocrine pancreatic insufficiency than the secretin-caerulein test. AIMS To evaluate faecal pancreatic elastase-1 assay in monitoring patients with coeliac disease. PATIENTS Thirty patients with coeliac disease (11 m; age range 1-7 years) completed a 2-month follow-up. As controls, we studied two sex-, age-matched patient groups: a) 15 patients with cystic fibrosis, b) 40 surgical patients without gastroenterological disease. METHODS In all coeliac subjects, stools were collected over 24 hours at diagnosis and then 30 and 60 days after commencement of the gluten-free diet; on a sample of the faeces we assayed elastase-1 activity. In the control patients, faeces were collected over 24 hours for elastase-1 assay only once. The coeliac patients only underwent the secretin-caerulein test, at diagnosis. RESULTS Ten out of 30 coeliac patients (33%) had subnormal faecal elastase-1 values at diagnosis, while all the surgical controls had values within the normal range; median values in coeliac patients were significantly lower than those of the surgical controls (median 287 mcg/g, 95% CI 271-430, versus 487 mcg/g, 95% CI 426-538, p < 0.007). Cystic fibrosis patient values (median 10 mcg/g, 95% CI 7-155) were significantly lower than both those of coeliac patients and those of the surgical controls (p < 0.0001). The secretin-caerulein test showed that 7/30 coeliac patients (23%) had a deficiency in one or more pancreatic enzymes; all these subjects had below normal faecal elastase-1 values. During the follow-up, we observed a progressive reduction in the number of coeliacs with pancreatic impairment; however, after 2 months of gluten-free diet, faecal elastase-1 deficiency persisted in 2/30 coeliacs. CONCLUSIONS Faecal elastase-1 determination in coeliac patients reveals a similar frequency and duration of pancreatic impairment to those observed in studies performed using the faecal chymotrypsin assay; a reduction in faecal elastase-1 values can be linked to "non-typical pancreatic diseases".

Abstract
BACKGROUND Recent research has shown that cow's milk protein intolerance (CMPI) often persists beyond 4 years of age. AIMS To evaluate the clinical and immunological characteristics of a group of infants with persistent CMPI. PATIENTS AND METHODS Twelve infants (6 m, 6f) with persistent CMPI were followed up from birth until a median age of 5 years. The patients underwent CMP challenge each year to evaluate CMP-tolerance. As controls we followed 26 infants (12 m, 14 f) with CMPI that resolved within 1-2 years. RESULTS A family history of atopic disease was found in 10/12 patients with persistent CMPI and in 10/26 controls (P<0.01). Clinical presentation changed over time: at onset symptoms were prevalently gastrointestinal, while at the end of the study there was an increased frequency of wheezing and constipation and a higher frequency of delayed reactions to CMP-challenge than at study commencement (9/12 vs 2/12; P<0.007). 11/12 infants with persistent CMPI and 3/26 controls (P<0.0001) presented multiple food intolerance. During the observation period 9/12 infants with persistent CMPI and 2/26 controls showed atopic disease: asthma, rhinitis, eczema (P < 0.0001). CONCLUSIONS Persistent CMPI forms are characterized by: (a) considerable importance of familial atopic disease; (b) change in CMPI manifestations over time and more prolonged delay between CMP consumption and manifestation of symptoms; (c) very high frequency of multiple food intolerance and allergic diseases.
