Esophageal food bolus impaction in pediatric age. J Pediatr Gastroenterol Nutr 2024. [PMID: 38623937 DOI: 10.1002/jpn3.12222] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/13/2023] [Revised: 02/02/2024] [Accepted: 02/08/2024] [Indexed: 04/17/2024]
Abstract
OBJECTIVES Esophageal food impaction (EFI) is the sudden onset of dysphagia that occurs when a food bolus becomes lodged in the esophagus, requiring endoscopic removal. Scientific data on the prevalence and causes of EFI in children is lacking. The aim of this study was to provide further insights into EFI episodes in children. METHODS We have prospectively enrolled all children admitted for a first episode of EFI between March 2018 and March 2023. A fluoroscopic contrast study was performed in all patients to confirm the boluses and assess their position. Boluses were extracted by esophagogastroduodenoscopies, and esophageal biopsies were routinely obtained for histologic evaluation. RESULTS Over the study period, 41 children were admitted for a first episode of food impaction. Drooling was the most commonly reported symptom. Half children experiencing a first episode of food bolus were diagnosed with EoE (20/41, 48.8%). Almost a fourth of the episodes subtended a different condition, such as esophageal anastomotic, peptic or congenital strictures, stricturing caustic esophagitis, esophageal duplication, and achalasia. In the last fourth of patients the cause of EFI was not identified and thus probably related to quick eating and inadequate chewing of food. DISCUSSION Our study represents the largest known series of pediatric patients evaluated for food bolus impaction. Our main finding is the high frequency of EoE, which accounts for a half of EFI episodes in pediatric age, especially in older children. This finding highlights the importance of obtaining esophageal biopsies after the endoscopic bolus removal in children with EFI to provide a complete diagnostic evaluation.

Italian guidelines for the management of irritable bowel syndrome in children and adolescents : Joint Consensus from the Italian Societies of: Gastroenterology, Hepatology and Pediatric Nutrition (SIGENP), Pediatrics (SIP), Gastroenterology and Endoscopy (SIGE) and Neurogastroenterology and Motility (SINGEM). Ital J Pediatr 2024; 50:51.

Abstract
The irritable bowel syndrome (IBS) is a functional gastrointestinal disorder (FGID), whose prevalence has widely increased in pediatric population during the past two decades. The exact pathophysiological mechanism underlying IBS is still uncertain, thus resulting in challenging diagnosis and management. Experts from 4 Italian Societies participated in a Delphi consensus, searching medical literature and voting process on 22 statements on both diagnosis and management of IBS in children. Recommendations and levels of evidence were evaluated according to the grading of recommendations, assessment, development, and evaluation (GRADE) criteria. Consensus was reached for all statements. These guidelines suggest a positive diagnostic strategy within a symptom-based approach, comprehensive of psychological comorbidities assessment, alarm signs and symptoms' exclusion, testing for celiac disease and, under specific circumstances, fecal calprotectin and C-reactive protein. Consensus also suggests to rule out constipation in case of therapeutic failure. Conversely, routine stool testing for enteric pathogens, testing for food allergy/intolerance or small intestinal bacterial overgrowth are not recommended. Colonoscopy is recommended only in patients with alarm features. Regarding treatment, the consensus strongly suggests a dietary approach, psychologically directed therapies and, in specific conditions, gut-brain neuromodulators, under specialist supervision. Conditional recommendation was provided for both probiotics and specific fibers supplementation. Polyethylene glycol achieved consensus recommendation for specific subtypes of IBS. Secretagogues and 5-HT4 agonists are not recommended in children with IBS-C. Certain complementary alternative therapies, antispasmodics and, in specific IBS subtypes, loperamide and rifaximin could be considered.

Abstract
The irritable bowel syndrome (IBS) is a chronic disorder of gut-brain interaction. IBS is still associated with areas of uncertainties, especially regarding the optimal diagnostic work-up and the more appropriate management. Experts from 7 Italian Societies conducted a Delphi consensus with literature summary and voting process on 27 statements. Recommendations and quality of evidence were evaluated using the grading of recommendations, assessment, development, and evaluation (GRADE) criteria. Consensus was defined as >80% agreement and reached for all statements. In terms of diagnosis, the consensus supports a positive diagnostic strategy with a symptom-based approach, including the psychological comorbidities assessment and the exclusion of alarm symptoms, together with the digital rectal examination, full blood count, C-reactive protein, serology for coeliac disease, and fecal calprotectin assessment. Colonoscopy should be recommended in patients with alarm features. Regarding treatment, the consensus strongly supports a dietary approach for patients with IBS, the use of soluble fiber, secretagogues, tricyclic antidepressants, psychologically directed therapies and, only in specific IBS subtypes, rifaximin. A conditional recommendation was achieved for probiotics, polyethylene glycol, antispasmodics, selective serotonin reuptake inhibitors and, only in specific IBS subtypes, 5-HT3 antagonists, 5-HT4 agonists, bile acid sequestrants.

Pediatric emergency care admissions for somatic symptom disorders during the COVID-19 pandemic. Eur J Pediatr 2023; 182:957-964. [PMID: 36459226 PMCID: PMC9716529 DOI: 10.1007/s00431-022-04687-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/17/2022] [Revised: 10/25/2022] [Accepted: 10/31/2022] [Indexed: 12/03/2022]
Abstract
During the COVID-19 pandemic, children and adolescents with psychiatric disorders experienced an exacerbation of their symptoms with more access to the emergency department (ED). However, little is known about the experience of somatic symptom disorders (SSDs) during the COVID-19 pandemic in children. Therefore, we aimed to compare the rates of pediatric ED admissions for SSDs before and during the COVID-19 pandemic and to understand whether the relative risk of ED admissions for SSDs changed between the two periods. We retrospectively enrolled all children between 4 and 14 years admitted for SSDs in the pediatric ED of Santobono-Pausilipon Hospital, Naples, Italy, from March 11th, 2020, to March 11th, 2021 (pandemic period), and in the same time period of the previous year (pre-pandemic period). We identified 205/95,743 (0,21%) children with SSDs presenting in ED in the pre-pandemic year and 160/40,165 (0,39%) in the pandemic year (p < 0.05). Considering the accesses for age, we observed a relative decrease of the accesses for SSDs over 12 years old (IRR 0,59; CI 0,39-0,88), while we found no differences under 12 years old (IRR 0,87; CI 0,68-1,10). Conclusion: In this study, we found that despite the massive decrease in pediatric admissions due to the COVID-19 pandemic, somatic symptom disorders' admissions to the pediatric ED increased, suggesting an impact of the pandemic also on pediatric psychiatric disorders. What is Known: • During the COVID -19 pandemic, children and adolescents with a psychiatric disorder experienced exacerbation of their symptoms with more accesses in Emergency Department. What is New: • We found that despite the massive decrease of the pediatric admissions due to the COVID-19 pandemic, somatic symptom disorders admissions in healthy children to the pediatric Emergency Department increased ,suggesting an impact of the pandemic also on the pediatric psychiatric disorders.

Prevalence and features of delirium in older patients admitted to rehabilitation facilities: a multicenter study. Aging Clin Exp Res 2022; 34:1827-1835. [PMID: 35396698 DOI: 10.1007/s40520-022-02099-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2022] [Accepted: 02/16/2022] [Indexed: 11/01/2022]
Abstract
BACKGROUND Delirium is thought to be common across various settings of care; however, still little research has been conducted in rehabilitation. AIM We investigated the prevalence of delirium, its features and motor subtypes in older patients admitted to rehabilitation facilities during the three editions of the "Delirium Day project". METHODS We conducted a cross-sectional study in which 1237 older patients (age ≥ 65 years old) admitted to 50 Italian rehabilitation wards during the three editions of the "Delirium Day project" (2015 to 2017) were included. Delirium was evaluated through the 4AT and its motor subtype with the Delirium Motor Subtype Scale. RESULTS Delirium was detected in 226 patients (18%), and the most recurrent motor subtype was mixed (37%), followed by hypoactive (26%), hyperactive (21%) and non-motor one (16%). In a multivariate Poisson regression model with robust variance, factors associated with delirium were: disability in basic (PR 1.48, 95%CI: 1.17-1.9, p value 0.001) and instrumental activities of daily living (PR 1.58, 95%CI: 1.08-2.32, p value 0.018), dementia (PR 2.10, 95%CI: 1.62-2.73, p value < 0.0001), typical antipsychotics (PR 1.47, 95%CI: 1.10-1.95, p value 0.008), antidepressants other than selective serotonin reuptake inhibitors (PR 1.3, 95%CI: 1.02-1.66, p value 0.035), and physical restraints (PR 2.37, 95%CI: 1.68-3.36, p value < 0.0001). CONCLUSION This multicenter study reports that 2 out 10 patients admitted to rehabilitations had delirium on the index day. Mixed delirium was the most prevalent subtype. Delirium was associated with unmodifiable (dementia, disability) and modifiable (physical restraints, medications) factors. Identification of these factors should prompt specific interventions aimed to prevent or mitigate delirium.

The association between low skeletal muscle mass and delirium: results from the nationwide multi-centre Italian Delirium Day 2017. Aging Clin Exp Res 2022; 34:349-357. [PMID: 34417734 PMCID: PMC8847195 DOI: 10.1007/s40520-021-01950-8] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/10/2021] [Accepted: 07/31/2021] [Indexed: 01/22/2023]
Abstract
Introduction Delirium and sarcopenia are common, although underdiagnosed, geriatric
syndromes. Several pathological mechanisms can link delirium and low skeletal muscle mass, but few studies have investigated their association. We aimed to investigate (1) the association between delirium and low skeletal muscle mass and (2) the possible role of calf circumference mass in finding cases with delirium. Methods The analyses were conducted employing the cross-sectional “Delirium Day” initiative, on patient 65 years and older admitted to acute hospital medical wards, emergency departments, rehabilitation wards, nursing homes and hospices in Italy in 2017. Delirium was diagnosed as a 4 + score at the 4-AT scale. Low skeletal muscle mass was operationally defined as calf circumference ≤ 34 cm in males and ≤ 33 cm in females. Logistic regression models were used to investigate the association between low skeletal muscle mass and delirium. The discriminative ability of calf circumference was evaluated using non-parametric ROC analyses. Results A sample of 1675 patients was analyzed. In total, 73.6% of participants had low skeletal muscle mass and 24.1% exhibited delirium. Low skeletal muscle mass and delirium showed an independent association (OR: 1.50; 95% CI 1.09–2.08). In the subsample of patients without a diagnosis of dementia, the inclusion of calf circumference in a model based on age and sex significantly improved its discriminative accuracy [area under the curve (AUC) 0.69 vs 0.57, p < 0.001]. Discussion and conclusion Low muscle mass is independently associated with delirium. In patients without a previous diagnosis of dementia, calf circumference may help to better identify those who develop delirium.

Use of the functional luminal imaging probe in pediatrics: A comparison study of patients with achalasia before and after endoscopic dilation and non-achalasia controls. Neurogastroenterol Motil 2021; 33:e14133. [PMID: 33871917 PMCID: PMC8523575 DOI: 10.1111/nmo.14133] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/30/2020] [Revised: 03/08/2021] [Accepted: 03/09/2021] [Indexed: 01/02/2023]
Abstract
BACKGROUND Achalasia is an esophageal motility disorder characterized by esophagogastric junction (EGJ) dysfunction and impaired esophageal peristalsis with significant impact on quality of life. While the functional luminal imaging probe (FLIP) has been used to assess EGJ distensibility in achalasia, its clinical utility in pediatrics is limited due to absence of normative values and correlations with clinical outcomes in children. Thus, we sought to evaluate FLIP's use in a pediatric achalasia cohort undergoing dilations and non-achalasia controls. METHODS We conducted a retrospective study of pediatric patients with achalasia who underwent FLIP before and immediately after balloon dilations and compared to a non-achalasia cohort. KEY RESULTS Thirty patients with achalasia (mean age, 15.2 years; 40% female), including fourteen treatment-naïve and thirteen controls (mean age, 7.9 years; 61% female) were identified. Median EGJ distensibility index (EGJ-DI) 2.07 mm2 mmHg-1 and diameter (9.23 mm) in treatment-naïve patients were significantly lower compared to controls (EGJ-DI 6.8 mm2 mmHg-1 ; diameter 18.61 mm; (p < 0.001). Balloon dilations resulted in a significant increase in EGJ-DI immediately after the dilation, particularly in treatment-naïve patients (p < 0.001), and a significant improvement in Eckardt scores (p < 0.001). CONCLUSIONS & INFERENCES Functional luminal imaging probe measurements of EGJ-DI in pediatric patients with achalasia are mostly consistent with adult findings. However, normal EGJ-DI is seen in symptomatic patients, including treatment-naive, highlighting the need for pediatric reference data. Balloon dilations achieve a significant increase in EGJ-DI with improvement in Eckardt scores, confirming the therapeutic value of dilations in achalasia management.

Abstract
BACKGROUND High-resolution anorectal manometry (HR-ARM) is expected to be better than conventional manometry. Our aim was to characterize HR-ARM pressures in children with functional constipation (FC), with or without fecal incontinence (FI). METHODS Children with diagnosis of FC, with or without FI, according to Rome-IV criteria, were enrolled. All patients underwent HR-ARM using 24-channel water-perfused catheter. RESULTS Twenty-nine consecutive children (M/F: 21/8; mean age ± SD: 9.5 ± 3.1 years; range 4-15), of whom 21 affected by FC without FI (mean age ± SD: 9.3 ± 3.23 years) and 8 affected by FC with FI (mean age ± SD: 10.2 ± 3.08 years), were enrolled. No significant differences were found regard to gender and age. The analysis of HR-ARM 3D plots demonstrated asymmetry of the anal canal, with higher pressures in distal halves. Comparing pressures between the two groups, we found lower values in FC with FI than in FC without FI group, with a statistically significance for maximum and mean resting pressures (P = .032 and P = .008, respectively). When evaluating our study population respect to asymptomatic children, we found lower resting pressures, lower maximum squeeze pressure, and higher rectoanal inhibitory reflex (RAIR) values. CONCLUSIONS Our data demonstrate that HR-ARM pressures at rest and during squeezing in FC with FI children are lower than FC without FI subjects, particularly in anteroposterior quadrants. Compared to children without lower gastrointestinal symptoms, children with FC with or without FI show lower pressures and higher values of RAIR.

Abstract
BACKGROUND & AIMS We aimed to compare the efficacy of a partially hydrolysed formula (pHF) with reduced lactose content and Lactobacillus reuteri DSM 17938 (L. reuteri) with a standard formula in infant colic (IC). METHODS We performed a double blind, parallel-group randomized active-controlled. Inclusion criteria were: exclusively formula fed, full term infants, aged <4 months, diagnosis of IC. All the enrolled infants were randomized to receive either pHF with reduced lactose content and L. reuteri (Group A) or standard formula (Group B). The treatment duration was 4 weeks and children were followed-up to 8 weeks. The primary outcome was the mean infant crying duration at 28 days. RESULTS Two-hundred-forty-one children were randomized to the treatments' group (Group A = 124; Group B = 117). Mean daily crying time at 28th day was significantly lower in Group B when compared to Group A [104.7 (87-122.4) versus 146.4 min (129.2-163.7), treatment effect -41.8 (95% C.I.: -66.5 to -17.1), p = 0.001]. No significant adverse event was reported in both groups. CONCLUSIONS Standard formula showed a lower overall crying time respect to the intervention formula (ClinicalTrials.govNCT02813772).

Peritoneal tuberculosis mimicking carcinomatous ascites in a child living in a low prevalence country: a case report. Ital J Pediatr 2020; 46:49.

Abstract
BACKGROUND Ascites can develop as a consequence of a number of diseases in childhood. Despite chronic liver disease is the most common cause, several conditions can lead to ascites also in the absence of liver dysfunction. As non-cirrhotic ascites shows a high degree of overlapping sign and symptoms it is still a challenge for physicians. CASE PRESENTATION A 8-year-old Caucasian girl was referred for fever, vomit and diarrhea occurred over the past few weeks. Physical examination showed timpanitic distension of the abdomen with marked tenderness and increased abdominal wall rigidity. Abdominal imaging showed diffuse ascites and thickened omentum and bowel wall. Blood tests showed increased C- reactive protein levels and decreased lymphocyte count. Specific treatment for inflammatory bowel disease was started. Persisting of ascites required additional investigations. Positive tuberculin skin test and Interferon Gamma release assay (IGRA) as well as increased Ca125 serum concentrations were found. Computed tomography scan showed mediastinal and mesenteric adenopathies and diffuse smooth thickening of the omentum with significant enhancement (omental cake-like). Ascitic fluid analysis revealed high leucocytes and protein levels. Presumptive diagnosis of peritoneal tuberculosis (PTB) was made. Antituberculous treatment resulted in the resolution of ascites and normalization of lymphocyte count and Ca125 serum concentrations. CONCLUSIONS PTB is still possible in low-prevalence countries. As it is a great mimicker of other abdominal pathology whose treatment might worsen tuberculosis progression, clinical suspicion and adequate screening are required to avoid unnecessary interventions and delayed treatment. Ca125 is a non-specific marker of peritoneal inflammation but it might be helpful in monitoring the treatment response.

Abstract
OBJECTIVE This narrative review aimed to provide practitioners a synthesis of the current knowledge on the role of a low Fermentable Oligosaccharides Disaccharides Monosaccharides and Polyols diet in reducing symptoms associated with functional abdominal pain disorders in children. This review is focused on the pathophysiology, efficacy and criticism of low Fermentable Oligosaccharides Disaccharides Monosaccharides and Polyols diet in children. SOURCES Cochrane Database, Pubmed and Embase were searched using specific terms for Fermentable Oligosaccharides Disaccharides Monosaccharides and Polyols diet interventions and functional abdominal pain disorders. SUMMARY OF THE FINDINGS In children, only one Randomized Control Trial and one open-label study reported positive results of low Fermentable Oligosaccharides Disaccharides Monosaccharides and Polyols diet; one Randomized Control Trial showed exacerbation of symptoms with fructans in children with Irritable Bowel Syndrome; no effect was found for the lactose-free diet whilst fructose-restricted diets were effective in 5/6 studies. CONCLUSIONS In children there are few trials evaluating low Fermentable Oligosaccharides Disaccharides Monosaccharides and Polyols in functional abdominal pain disorders, with encouraging data on the therapeutic efficacy particularly of fructose-restricted diet. Additional efforts are still needed to fill this research gap and clarify the most efficient way for tailoring dietary restrictions based on the patient's tolerance and/or identification of potential biomarkers of low Fermentable Oligosaccharides Disaccharides Monosaccharides and Polyols efficacy, to maintain nutritional adequacy and to simplify the adherence to diet by labeling Fermentable Oligosaccharides Disaccharides Monosaccharides and Polyols content in commercial products.

Does a low FODMAPs diet reduce symptoms of functional abdominal pain disorders? A systematic review in adult and paediatric population, on behalf of Italian Society of Pediatrics. Ital J Pediatr 2018; 44:53.

Abstract
Background Despite the rising of the Functional Gastrointestinal Disorders (FGIDs)’ incidence in the last years, the etio-pathogenesis of FGIDs remains unclear. The diet seems to play an important role in these disorders. Indeed, at least two thirds of adult patients with Irritable Bowel Syndrome (IBS) and of children with FGIDs perceive their GI symptoms to be food-related. In particular, in the last years, more interest has been focused in the low Fermentable Oligosaccharides, Disaccharides, Monosaccharides, and Polyol (FODMAPs) diet. Aims To provide a systematic review on the efficacy of a low FODMAPs diet in reducing symptoms associated with functional abdominal pain disorders. Methods Cochrane Library, MEDLINE (via Pubmed), and EMBASE databases from inception to June 2017 were searched. We included randomized controlled trials (RCTs), prospective and retrospective studies, systematic reviews and meta-analyses, reporting the efficacy of the FODMAPs diet intervention in FGIDs patients. Results Nineteen studies were eligible. A FODMAPs-restricted diet is beneficial in 12/13 intervention trials. The low FODMAPs diet improves overall GI symptoms, especially abdominal pain and bloating. In children, only one study reported positive results of a low FODMAPs diet. No effect was found for the lactose free diet whilst fructose-restricted diet was effective in 3/4 studies. The duration of the intervention was very different among the studies, ranging from 2 days to 16 months, and from 3 and 9 weeks for the RCTs. The majority of the trials presented differences in symptoms scoring scales, diet, food diaries, and food frequencies questionnaire. Conclusions The FODMAPs-restricted diet may be an effective dietary intervention for reducing IBS symptoms in adults. In children, there are promising data, although only one randomized double-blind study exists and further data are needed to better clarify the role of FODMAPs and fructose-restricted diet in IBS. The current evidence does not support the use of a lactose-restricted diet in children with FGIDs.

Abstract
UNLABELLED A score for identifying post-hip-fracture surgery patients at various levels (high, medium, and low) of risk for unsuccessful recovery of pre-fracture walking ability was developed. Three hundred ninety-eight HF patients were enrolled in the study. The score significantly and independently predicted failure to walk independently at discharge, failure to walk independently after 12 months, and death after 12 months. The score may be useful for clinicians and healthcare administrators to target populations for rehabilitative programs. INTRODUCTION To develop a model predicting at the time that elderly hip-fracture (HF) patients undergo rehabilitation if they will have recovered walking independence at discharge. METHODS Data from all patients admitted to a Department of Rehabilitation in Italy between January 2001 and June 2008 after HF surgery were used. Variables concerning cognitive, clinical, functional, and social parameters were evaluated. Predominant measures were identified through correspondence analysis, and a variable score was defined. Three risk classes (minimum, moderate, and high) were identified and univariate and multivariate logistic regressions were used to assess the model's predictivity and risk classes for the various outcomes. RESULTS Three hundred ninety-eight HF patients were enrolled. The variables selected to construct the score were age, gender, body mass index, number of drugs being taken, the Mini Mental State Examination, the Instrumental Activity of Daily Living, and the pre-fracture Barthel index. According to univariate analysis, the score was not better than the pre-fracture Barthel's index, but, according to multivariate analysis, it was an independent predictor for all the outcomes, while the pre-fracture Barthel index predicted only outcomes at discharge. In particular, the score significantly predicted failure to walk independently at discharge, failure to walk independently after 12 months, and death after 12 months. CONCLUSIONS A method of identifying post-HF surgery patients at various levels (high-, medium-, and low-) of risk for unsuccessful recovery of pre-fracture walking ability has been designed. The method may be useful for clinicians and healthcare administrators to target populations for rehabilitative programs.

Abstract
BACKGROUND An association between coeliac disease (CD) and functional gastrointestinal disorders (FGIDs) has at present only been demonstrated in adults. AIMS To assess the prevalence of FGIDs at 1 year and the role of psychological aspects on the development of FGIDs in CD children. METHODS One-hundred consecutive CD children (36M and 64F) were followed up for 1 year. Fifty-six children (25M and 31F) represented the control group. All children and/or their parents completed validated questionnaires for GI symptoms, depression, and anxiety. GI symptoms at diagnosis and after 1 year of gluten-free diet (GFD) were compared. RESULTS Twenty-three/82 (28%) CD patients followed up prospectively, on GFD from at least 1 year, fulfilled the Rome III criteria for FGIDs compared with 5/56 (8.9%) controls (P = 0.008; χ² = 6.8; OR: 3.97; 95% CI: 1.40-11.21). Children complaining with GI symptoms alone [21/52 (40.3%)] more likely fulfilled Rome III criteria for FGIDs after 1 year of GFD than children with extra-intestinal symptoms (P = 0.045). CD children with FGDIs presented significantly higher anxiety and depression compared to CD children without FGIDs and controls (P = 0.02). CONCLUSIONS This study demonstrates that children with CD on a GFD for a year have a much higher prevalence of functional GI symptoms than do controls. Whether the risk is due to the residua of a chronic inflammatory process, and/or due to psychological factors remains to be further tested.

Abstract
BACKGROUND Proton pump inhibitors (PPIs) and H(2) receptor antagonists (H(2)RAs) may play an important role on the onset of Clostridium difficile-associated disease (CDAD) in adults. The impact of Clostridium difficile on children treated with gastric acid-suppressing agents remains unknown. AIM To investigate the relationship between CDAD and exposure to acid suppressive therapy in hospitalized paediatric patients. METHODS We reviewed the medical records of children, with a diagnosis of protracted diarrhoea and abdominal pain, whose stool was analysed for C. difficile toxins. We identified 68 patients with CDAD. For each patient, we randomly selected one control subjects with stool analysis negative for C. difficile. Comorbid illnesses, previous hospitalizations, antibiotics, corticosteroids, immunosuppressants and gastric acid suppressing exposures were recorded. RESULTS The use of PPI was significantly higher in C. difficile positive group compared with C. difficile negative group [odds ratio (OR): = 4.5; 95% confidence interval (CI) = 1.4-14.4]. We also found a trend for the use of H(2)RAs in patients infected by C. difficile compared with C. difficile negative comparison group (OR: = 3.8; 95% CI = 0.7-18.9). CONCLUSIONS Children exposed to PPIs therapy seem to be at higher risk for the development of Clostridium difficile-associated disease.

Abstract
Functional Gastrointestinal Disorders (FGIDs) are defined as a variable combination of chronic or recurrent gastrointestinal symptoms, age dependent, not explained by structural or biochemical abnormalities. Recurrent gastrointestinal disorders, especially abdominal pain, are one of the most common reasons for medical consultation among children and adolescents. A population-based study demonstrated that 28-46% of school age children complain of abdominal pain each week. Only in 10% of the cases an organic cause can be identified, while most of the children and adolescents who present these symptoms have a functional disorder without any evidence of disease. FGIDs significantly influence the quality of life of affected children and have a big social impact related to socialization, school absences and could have long-term psychological implications. A complete understanding of the pathophysiology of FGIDs remains elusive. FGIDs are a multifactorial condition and diverse pathophysiologic mechanisms appear to contribute to them, including altered motility, visceral hyperalgesia, brain-gut disturbances, genetic and environmental factors, and psychosocial upsets, among others. In 2006 the new version of the Questionnaire on Pediatric Gastrointestinal Symptoms (QPGS) based on Rome III Criteria (QPGS-RIII) was created, in order to validate such criteria and to facilitate the diagnosis of FGDIs in children and adolescents. The Italian translation of the QPGS-RIII has been realized by our research group to spread a valid and universal method to screen the children potentially affected by FGDIs.

Abstract
AIMS To assess the presence of virulence genes in environmental and foodborne Escherichia coli isolates using the TaqMan PCR system. METHODS AND RESULTS Three TaqMan pathogen detection kits called O157:H7, StxI and StxII were used to investigate the presence of virulence genes in Escherichia coli isolates. All 54 foodborne E. coli O157:H7 isolates showed expected results using these kits. Ninety (15%) of 604 environmental isolates gave positive amplification with an O157:H7-specific kit. TaqMan PCR amplification products from these 90 isolates were analysed by agarose gel electrophoresis, and 90% (81 of 90) of the environmental samples contained the expected PCR product. Sixty-six of these 90 were chosen for serotyping tests and only 35% (23 of 66) showed agglutination with both anti-O157 and anti-H7 antibodies. Further ribotyping of 16 sero-positive isolates in an automated Riboprinter did not identify these to be O157:H7. Multiplex PCR with primers for eaeA, stxI and stxII genes was used to confirm the TaqMan results in 10 selected environmental isolates. CONCLUSIONS All three TaqMan pathogen detection kits were useful for virulence gene analysis of prescreened foodborne O157:H7 isolates, while the O157:H7-specific kit may not be suitable for virulence gene analysis of environmental E. coli isolates, because of high false positive identification. SIGNIFICANCE AND IMPACT OF THE STUDY The ability to rapidly identify the presence of pathogenic E. coli in food or environmental samples is essential to avert outbreaks. These results are of importance to microbiologists seeking to use TaqMan PCR to rapidly identify pathogenic E. coli in environmental samples. Furthermore, serotyping may not be a reliable method for identification of O157:H7 strains.

Abstract
There is a malignant transformation in object relations resulting in an identification with an omnipotent and cruel object resulting in an identity transformation. If the tension, desperation, and dissociation increase, serial murder becomes spree murder. The presence of pathological narcissism and psychopathic tendencies are of diagnostic significance in understanding the murderer's personality functioning and motivation to kill. Meloy (1988) considered the degree of sadism and aggression combined with narcissistic qualities to reflect the "malignancy" of the psychopathic disturbance where gratification (of aggression) occurs in the service of narcissistic functioning--that is, cruelty toward others in the form of a triumphant victory over a rejecting object. Meloy also believes that dissociation is ubiquitious in the psychopath. The initial murder of the serial murderer may reflect a "new identity." The pathological object-relations of narcissism and the malignant narcissism are important diagnostic indicators in the personality functioning of serial killers and the occurrence of these phenomena is a significant factor in the formation of the personalities of serial killers, their inner motivations, and their pattern of commission.

Abstract
The microbial processes that occur in the subsurface under a typical Midwest agricultural soil were studied. A 26-m bore was installed in November of 1988 at a site of the Purdue University Agronomy Research Center. Aseptic collections of soil materials were made at 17 different depths. Physical analysis indicated that the site contained up to 14 different strata. The site materials were primarily glacial tills with a high carbonate content. The N, P, and organic C contents of sediments tended to decrease with depth. Ambient water content was generally less than the water content, which corresponds to a -0.3-bar equivalent. No pesticides were detected in the samples, and degradation of added 14C-labeled pesticides (atrazine and metolachlor) was not detected in slurry incubations of up to 128 days. The sorption of atrazine and metolachlor was correlated with the clay content of the sediments. Microbial biomass (determined by direct microscopic count, viable count, and phospholipid assay) in the tills was lower than in either the surface materials or the aquifer located at 25 m. The biodegradation of glucose and phenol occurred rapidly and without a lag in samples from the aquifer capillary fringe, saturated zone, and surface soils. In contrast, lag periods and smaller biodegradation rates were found in the till samples. Subsurface sediments are rich in microbial numbers and activity. The most active strata appear to be transmissive layers in the saturated zone. This implies that the availability of water may limit activity in the profile.

Abstract
The author presents an initial brief description of several viewpoints regarding object loss. He develops a case history in the course of describing a psychotherapy that provides a view of the patient experiencing a current loss as having the complicated influences of multiple previous losses for which she has felt guilty and experiences a sense of helplessness. The intensity of the current loss is related to the patient's overdetermined needs for attachment and mastery of past losses. The treatment allows the psychological development to unfold with the patient's associations and dreams. The resolution of grief is dealt with in the context of a short term (three month) psychotherapy which allows some insight into the defense mechanisms (repression) and feelings of guilt associated with loss. The transference manifestations were not emphasized in the treatment because of the defined limited nature of the task.

Abstract
This article includes a discussion of several factors in the development of unresolved grief and the emergence of a different state of mind, a self-image that is less able to cope with the stress of loss. Emphasis is placed on the issue of previous sensitization to loss stemming from childhood experiences. A case example is presented to illustrate the treatment of unresolved grief and the need to recognize the importance of developmental experiences in the patient's current mode of dealing with the stress of loss. Some suggestions are presented to assist the busy physician in dealing with patients who have experienced infant loss and in deciding when to refer such patients to psychiatrists.
