Abstract
Congenital diarrheal disorders (CDDs) are a collection of rare, heterogeneous enteropathies with early onset and often severe outcomes. Here, we report a family of Ashkenazi Jewish descent, with 2 out of 3 children affected by CDD. Both affected children presented 3 days after birth with severe, intractable diarrhea. One child died from complications at age 17 months. The second child showed marked improvement, with resolution of most symptoms at 10 to 12 months of age. Using exome sequencing, we identified a rare splice site mutation in the DGAT1 gene and found that both affected children were homozygous carriers. Molecular analysis of the mutant allele indicated a total loss of function, with no detectable DGAT1 protein or activity produced. The precise cause of diarrhea is unknown, but we speculate that it relates to abnormal fat absorption and buildup of DGAT substrates in the intestinal mucosa. Our results identify DGAT1 loss-of-function mutations as a rare cause of CDDs. These findings prompt concern for DGAT1 inhibition in humans, which is being assessed for treating metabolic and other diseases.

Abstract
Celiac disease (CD) is an autoimmune disorder occurring in genetically susceptible subjects. The incidence of CD is around 1%, and it is much more common in first-degree relatives of CD patients, 10%-18%. However, the pattern of the genetic inheritance is still obscure. Environmental factors are undoubtedly affecting the disease's clinical presentation, time at presentation, and may have an effect on the characteristics of the disease. The clinical presentation of CD has shifted during the previous decades from the classical presentation in which the toddler suffers from diarrhea, constipation, vomiting, failure to thrive, abdominal distension, etc., to the child with a monosymptomatic presentation, such as anemia, as well as an enlarged list of extra-intestinal disorders. The diagnosis of CD is being established by symptoms consistent with CD and positive serology. The ultimate diagnosis should be made upon histological evaluation of the small bowel mucosa. The treatment of CD is a lifelong, strict gluten-free diet (GFD). Compliance with a GFD is quite difficult. Therefore, new strategies for prevention and treatment modalities other than GFD are greatly needed. Recently several promising therapeutic modalities have been developed; these include resuming traditional baking techniques. Another methodology is using probiotic-driven prolylendopeptidase. Another pathway to tackle the therapeutic option in CD is by down-regulation of the activity of zonulin-the active pump enabling gluten to enter the enterocytes. We are facing an era where other modalities beyond a GFD might allow CD patients to be able to tolerate occasionally a small amount of gluten in their diet.

Abstract
OBJECTIVE Diagnostic criteria for coeliac disease (CD) from the European Society for Paediatric Gastroenterology, Hepatology, and Nutrition (ESPGHAN) were published in 1990. Since then, the autoantigen in CD, tissue transglutaminase, has been identified; the perception of CD has changed from that of a rather uncommon enteropathy to a common multiorgan disease strongly dependent on the haplotypes human leukocyte antigen (HLA)-DQ2 and HLA-DQ8; and CD-specific antibody tests have improved. METHODS A panel of 17 experts defined CD and developed new diagnostic criteria based on the Delphi process. Two groups of patients were defined with different diagnostic approaches to diagnose CD: children with symptoms suggestive of CD (group 1) and asymptomatic children at increased risk for CD (group 2). The 2004 National Institutes of Health/Agency for Healthcare Research and Quality report and a systematic literature search on antibody tests for CD in paediatric patients covering the years 2004 to 2009 was the basis for the evidence-based recommendations on CD-specific antibody testing. RESULTS In group 1, the diagnosis of CD is based on symptoms, positive serology, and histology that is consistent with CD. If immunoglobulin A anti-tissue transglutaminase type 2 antibody titers are high (>10 times the upper limit of normal), then the option is to diagnose CD without duodenal biopsies by applying a strict protocol with further laboratory tests. In group 2, the diagnosis of CD is based on positive serology and histology. HLA-DQ2 and HLA-DQ8 testing is valuable because CD is unlikely if both haplotypes are negative. CONCLUSIONS The aim of the new guidelines was to achieve a high diagnostic accuracy and to reduce the burden for patients and their families. The performance of these guidelines in clinical practice should be evaluated prospectively.

Abstract
An organized intervention program in pre-pubertal children based on increased physical education and activity together with nutritional advice to the children and their families may prevent obesity. Children aged 9 to 11 received double hours of weekly physical education lessons and additional nutritional advice for 2 years. They were compared with a similar group who received standard physical education lessons only. A total of 82 study and 26 control children completed the 2 years of the project. Boys in the control group gained significantly more weight than the corresponding study group (8.4 kg vs 3.2 kg, respectively (P<0.016)), control delta body mass index (BMI) 1.02 vs study 0.44 (P<0.012). There was no significant change in the weight or BMI in the girls. We conclude that the prevention of obesity may be attained by similar programs. Hormonal effects and compliance at this age may be responsible for the sex differences in this study.

Abstract
BACKGROUND In the last decade the frequency of celiac disease diagnosis has increased in adults. OBJECTIVES To determine disease prevalence (including silent and potential disease) in this population group. METHODS We performed serologic screening of celiac disease in a representative and homogenous sample of a young adult general population in Israel, namely, 18 year old military conscripts, in 2003. Serologic screening was performed on serum samples randomly obtained from 850 healthy recruits (male/female = 1.1). Immunoglobulin A anti-tissue transglutaminase was determined by enzyme-linked immunosorbent assay. In cases of IgA deficiency, lgG anti-endomysial antibodies were determined. A small intestinal biopsy was offered to all patients with positive serology. RESULTS The prevalence of overt CD diagnosed prior to recruitment was 0.12% (0.1% in men and 0.14% in women). The overall prevalence based on positive serology was 1.1%. Six of nine subjects with positive serology agreed to undergo endoscopy and intestinal biopsies. In all cases, biopsies were compatible with celiac disease (five biopsies were graded as Marsh 3a and one as Marsh 3b). One subject previously reporting irritable bowel-like symptoms was diagnosed with overt atypical CD. The prevalence of overt CD diagnosed by screening was 0.12%. The ratio, of overt to silent CD was 1:8. No cases of potential CD were encountered. CONCLUSIONS Our findings suggest that CD is highly prevalent in the young adult population in Israel. Serologic screening for CD is a reliable and simple method for diagnosing this disease before symptoms or complications develop.

Abstract
BACKGROUND Changes in the scope of the field of paediatrics and the variability in primary paediatric care (PPC) and practice throughout Europe motivated the European Paediatric Association and Union of National European Paediatric Societies and Associations (EPA/UNEPSA) to establish a working group to discuss definitions of paediatric coverage in terms of age limits, find common denominators in the provision of PPC and examine the challenges and goals of 21st century paediatrics relevant to the continent. These issues were presented at the 2008 Europaediatrics in Istanbul, where a consensus declaration was drawn up and accepted by the EPA/UNEPSA Executive Committee. AIM To present an outline of the essential elements of the 2008 EPA/UNEPSA Executive Committee consensus declaration. CONCLUSION The definition of basic characteristics and the establishment of requirements for optimal PPC and practice are important steps in overcoming the differences among European countries and pave the way for an acceptable formulation of standardized high-quality paediatric medical care in Europe.

Abstract
UNLABELLED Very-low-birthweight (VLBW) infants suffer marked growth delay despite well-intentioned efforts at combining enteral and parenteral nutrition. Fear of necrotizing enterocolitis (NEC) has traditionally influenced neonatologists toward delaying and progressing slowly with enteral feeding, while supporting the infant with parenteral nutrition. Current evidence suggests significant benefits of enteral feeding that is started early and advanced at rates of 20-35 ml/kg/d. CONCLUSION We conclude that fear of inadequate growth should replace the fear of NEC in guiding nutritional strategies for these infants.

Abstract
OBJECTIVE To determine whether electronic counter-related pseudoleukopenia is a rare phenomenon or a systematic underestimation in children with acute infection/inflammation. METHODS We have used a simple slide test and image analysis to reveal the number of white blood cells and their degree of aggregation. The number of leukocytes counted by an electronic cell analyzer was divided by the number of cells counted on the slides creating an electronic cell-to-slide leukocyte count ratio. RESULTS A significant (P < 0.0005) negative (r = -0.314) correlation between the above mentioned ratios and the percent of aggregated leukocytes in the peripheral blood was found in a group of 239 children with various acute infections. Thus elevated leukocyte aggregation is associated with a relatively lower electronic analyzer cell count. CONCLUSIONS The appearance of aggregated leukocytes in the peripheral blood during acute infections might be associated with pseudoleukopenia. This phenomenon has been extensively described in the adult population and seems to exist in children as well.

Abstract
CONTEXT The identification and quantitation of the intensity of the acute-phase response at the point of care might be of clinical relevance. OBJECTIVE To report the possibility of automatic screening of unstained peripheral blood slides by using a 3-dimensional image analysis system. DESIGN Peripheral venous blood was obtained from children with acute inflammation/infection and examined by an automatic 3-dimensional image analyzer to detect the number of white blood cells as well as to reveal the degree of erythrocyte aggregation, a marker of the humoral phase response. RESULTS We included 66 children with acute bacterial infections and 59 with nonbacterial inflammation/infection; mean ages of the 2 groups were 4.3 +/- 3.9 years and 4.2 +/- 3.7 years, respectively (P = .91). The percentages of correct classifications based on discriminant analysis in predicting between bacterial and nonbacterial inflammation/infection were 61.3% by using the white blood cell count, 64.5% by using the percentage of granulocytes, 61.6% by using the degree of erythrocyte aggregation, and 59.2% by using the number of leukocytes counted on the unstained slides. The results of the receiver-operated characteristic curve analysis yielded an area under the curve of 0.714 (P < .001) for the number of granulocytes, 0.699 (P < .001) for the white blood cell count, 0.685 (P < .001) for the number of leukocytes on the slides, and 0.685 (P = .001) for the degree of erythrocyte aggregation. The correlation between the number of leukocytes by the electronic cell analyzer and the number of cells counted on the slides was highly significant (r = 0.85, P < .001). CONCLUSIONS It is feasible to use an automatic 3-dimensional image analyzer to reveal the different intensities of the acute-phase response between a group of children with an acute bacterial infection and another with nonbacterial inflammation/infection. These findings might be relevant for potential application at the point of care.

Abstract
OBJECTIVE Evaluation and follow-up of infants with cholelithiasis and pseudolithiasis in a pediatric ward. PATIENTS & METHODS Prospective study from April 1990 to October 2003 identified hospitalized infants younger than 2 years with ultrasonographic findings of cholelithiasis, choledocholithiasis or pseudolithiasis. Associated abnormalities or contributory factors were recorded and patients were followed for from 6 months to 13 years (mean, 4 years). RESULTS Thirty-four patients were diagnosed between the age of 3 weeks and 24 months. Thirteen (38%) had been treated with third-generation cephalosporins. Other associated factors were dehydration in 10 (29%), urinary tract infection in two (6%) and one each for cholestatic liver disease, total parenteral nutrition, immunoglobulin A deficiency and prematurity. Six infants (17%) had no known risk factor. Six additional patients were diagnosed by antenatal ultrasound. CONCLUSIONS Cholelithiasis in infants hospitalized for a variety of common pediatric conditions is not rare. Dehydration and treatment with third-generation cephalosporins are important associated factors. The classic risk factors of hemolysis and previous gastrointestinal surgery, were not found in our group. The overall prognosis was good. Pseudolithiasis disappeared in all infants. Of the 21 infants with cholelithiasis, only two developed cholecystitis. In nine infants, spontaneous resolution occurred. In the absence of other clinical or imaging evidence of biliary tract disease, conservative management is advised.

Abstract
Traumeel® S (Traumeel), a mixture of highly diluted
(10-1-10-9) extracts from
medicinal plants and minerals is widely used in humans to relieve trauma, inflammation
and degenerative processes. However, little is known about its possible effects on
the behavior of immune cells. The effects of Traumeel were examined in vitro on the ability
of resting and PHA-, PMA- or TNF-α-activated human T cells, monocytes, and gut epithelial
cells to secrete the prototypic pro-inflammatory
mediators IL-1β, TNF-α and IL-8 over a period
of 24-72 h. Traumeel inhibited the secretion of all three agents in resting, as well as
activated
immune cells. IL-β secretion was reduced by up to 70% in both resting and activated cells;
TNF-α secretion was reduced by up to 65 and 54%, respectively,
and IL-8 secretion was
reduced by 50% in both resting and activated cells (P<0.01 for all cells). Interestingly,
the effect appeared to be inversely dose-related; maximal inhibition (usually 30-60%
inhibition; P<0.01) was seen with dilutions of
10-3-10-6 of the Traumeel stock material. This
finding suggests that Traumeel does not inhibit immune cells functions by exerting a toxic
effect. Indeed, Traumeel did not affect T cell and monocyte proliferation. Although
additional studies are needed to clarify the mode of action of Traumeel and to demonstrate
causative relationship between the inhibition of cytokine/chemokine secretion in cell culture
and the reported clinical effects of the preparation, our in vitro results offer a mechanism for
the anti-inflammatory effects of Traumeel observed in clinical use.

Abstract
Acute Otitis Media (AOM) is the most common reason for pediatrician's visits and for antibiotic prescription in childhood. A significant rise in bacterial resistance to antibiotic treatment has been detected in recent years. Accordingly, the attitude towards antibiotic treatment for AOM has been re-evaluated. Due to various difficulties in ear examination, physicians overdiagnosis Otitis Media with Effusion (OME) as AOM, leading to unnecessary prescription of antibiotics. The natural history of AOM shows spontaneous improvement without complications. Studies that have examined antibiotic treatment versus placebo in AOM have shown only minimal advantage for the antibiotic therapy in symptom reduction. Critical appraisal of the literature according to Evidence-based Medicine (EBM) criteria has led to several meta-analyses that showed only a minor advantage for antibiotics over placebo in AOM. In the Netherlands, the approach to AOM is that of delayed prescribing: symptomatic therapy is given for the first 24-72 hours and an antibiotic drug is prescribed only if symptoms persist after this initial period. This review examines the difficulties in reaching an accurate diagnosis of AOM and describes the natural history of AOM and evaluates the studies and meta-analyses comparing antibiotics to placebo. The Dutch approach to AOM will be discussed as an option and a recommended basis for reduction in antibiotic prescriptions for AOM.

Abstract
OBJECTIVES To define the incidence of congenital cytomegalovirus (CMV) infection in a defined population in Israel as diagnosed by urine polymerase chain reaction (PCR), and to assess the utility of this method for screening for congenital CMV infection. DESIGN A convenient sample of urine specimens from asymptomatic newborns were subjected to CMV PCR. Positive results were validated by urine tube culture and by determination of serum CMV IgM antibodies. Maternal CMV IgG was determined in a representative sample of mothers. Newborns with positive urine specimens underwent full clinical evaluation. Epidemiological characteristics of the mothers were extracted from the medical records. SETTINGS Two medical centres in Israel with different population characteristics. PATIENTS A total of 2000 newborns (1000 in each medical centre). MAIN OUTCOME MEASURE Presence of CMV DNA in the urine. RESULTS Despite significant epidemiological differences between the populations in the two hospitals, the CMV seroprevalence was similar, 80.5% and 85%. Fourteen of the 2000 newborns screened (0.7%) were PCR positive. Urine culture was positive in nine of 10 specimens; IgM was positive in only two of 13 newborns with positive PCR. Eleven newborns underwent full or partial evaluation, and only one (9%) was symptomatic. CONCLUSIONS The incidence of congenital CMV infection in the study population was 0.7%; over 90% were asymptomatic. Urinary CMV PCR is a reliable, rapid, and convenient method, and thus may serve as a screening tool for the detection of congenital CMV infection.

Abstract
BACKGROUND Complementary medicine is gaining in public popularity, yet medical school curricula usually ignore it. OBJECTIVES To determine whether senior medical students are interested in learning principles of complementary or alternative medicine, to check their degree of familiarity with it, and to suggest a format for such studies in the medical curriculum. METHODS Senior medical students (n = 117) were surveyed by an anonymous questionnaire. RESULTS Seventy-nine percent of the senior medical students were interested in studying complementary or alternative medicine in medical school, and 65% were interested in applying these techniques to treat patients. Eighty-seven percent of students were familiar with some techniques of complementary medicine. CONCLUSIONS Senior medical students are interested in studying complementary and alternative medicine in medical school and in applying these techniques in practice.

Abstract
BACKGROUND There is substantial genetic variation among different isolates of Helicobacter pylori, which may affect the clinical outcome. The aims of this study were to find the common H. pylori genotypes in Israeli children and to look for a possible genotype-phenotype correlation. METHODS Ninety-eight H. pylori cultures were isolated from antral biopsy specimens of symptomatic Israeli children and were analyzed for vacA and iceA genotype and cagA and cagE status by polymerase chain reaction. RESULTS cagA and cagE genes were present in only 25.5% and 24.5%, respectively. The common vacA genotype was s2m2, which was found in 65%. Eleven specimens (11%) contained multiple vacA genotypes. iceA1 was found in 37% and iceA2 in 52% of cases. Both iceA alleles were found in 11%. Increased prevalence of iceA1 and cagE were observed in children with duodenal disease, although it did not reach significance. CONCLUSIONS The low prevalence of cagA and the high prevalence of vacA genotype s2m2 in Israeli pediatric patients are different from the genotype prevalence reported globally. However, similar findings have been reported in Egypt, indicating a possible geographic influence. There is a possible correlation between duodenal ulcer and cag E and ice A1 genotype, but the power of the study was too low to prove it.

Abstract
The objective of this study was to document the reduced acute phase response that appears in children with viral as opposed to bacterial infections. The white blood cell count (WBCC), the erythrocyte sedimentation rate (ESR), and leukocyte and erythrocyte adhesiveness/aggregation were determined in 36 children with acute bacterial infection, 29 children with viral infection, and 19 controls. A significant reduced WBCC, ESR, and leukocyte and erythrocyte adhesiveness/aggregation was noted in the children with acute viral infection as opposed to those with bacterial infection: 10,800 +/- 3600 and 20,000 +/- 10,000 cells/cm2, 29 +/- 21 and 53 +/- 35 mm Hg, 23 +/- 9 and 41 +/- 15%, and 3.4 +/- 5.1 and 9.8 +/- 13.6 microns, respectively. The results indicate that a reduced acute phase response can be observed in children with an acute viral infection. This can have diagnostic implications and pathophysiological consequences in terms of less flow impairment in the microcirculation due to less red and white blood cell aggregation.

Abstract
OBJECTIVES Oral budesonide has been found to be efficacious for mild to moderate Crohn's disease in adults, with equal improvement rates for budesonide and prednisone. We report the results of a retrospective study of budesonide treatment in mild to moderate Crohn's disease in children. STUDY DESIGN Charts of patients treated with budesonide (n = 62) with a pediatric Crohn's Disease Activity Index of 12.5 to 40 were compared with a cohort of 58 age-matched patients treated with prednisone. RESULTS Among children treated with budesonide, 48% had remission compared with 77% of the children treated with prednisone (P =.001). Among patients who had failed previous medical therapy with mesalamine, 59% had remission with budesonide (9 mg/day). Remission with prednisone occurred in 73% of children who failed to achieve remission with budesonide. Patients responding to budesonide had significantly milder disease compared with nonresponders who had remission while taking prednisone. CONCLUSIONS Budesonide is useful in mild to moderate Crohn's disease in children. It is more effective than mesalamine and antibiotics but less effective than prednisone. Budesonide should be considered for first-line therapy in mild to moderate Crohn's disease.

Abstract
BACKGROUND Stomatitis is a common consequence of chemotherapy and a condition for which there is little effective treatment. Although the management of patients with other chemotherapy-related toxicities has improved in recent years, the incidence of stomatitis is increasing because of more intensive treatment and is often a dose limiting factor in chemotherapy. The authors assessed the efficacy of a homeopathic remedy, TRAUMEEL S(R), in the management of chemotherapy-induced stomatitis in children undergoing bone marrow transplantation. METHODS A randomized, placebo-controlled, double-blind clinical trial was conducted in 32 patients ages 3-25 years who had undergone allogeneic (16 patients) or autologous (16 patients) stem cell transplantation. Of the 30 evaluable patients, 15 were assigned placebo, and 15 were assigned TRAUMEEL S both as a mouth rinse, administered five times daily from 2 days after transplantation for a minimum of 14 days, or until at least 2 days after all signs of stomatitis were absent. Stomatitis scores were evaluated according to the World Health Organization grading system for mucositis. RESULTS A total of five patients (33%) in the TRAUMEEL S treatment group did not develop stomatitis compared with only one patient (7%) in the placebo group. Stomatitis worsened in only 7 patients (47%) in the TRAUMEEL S treatment group compared with 14 patients (93%) in the placebo group. The mean area under the curve stomatitis scores were 10.4 in the TRAUMEEL S treatment group and 24.3 in the placebo group. This difference was statistically significant (P < 0.01). CONCLUSIONS This study indicates that TRAUMEEL S may reduce significantly the severity and duration of chemotherapy-induced stomatitis in children undergoing bone marrow transplantation.

Abstract
BACKGROUND Prevention of cigarette smoking is an important issue in public health policy. Since most adult smokers began smoking in childhood, understanding behavorial factors associated with smoking initiation would contribute to smoking initiation programs. Health-related behavior may vary between different ethnic groups. OBJECTIVES To determine the prevalence of smoking among Jewish and Arab adolescents in Jerusalem, and whether there are differences in smoking initiation between the two ethnic groups. METHODS We carried out a cross-sectional survey of all students in the 6th to 11th grades (age range 11-17 years) of a Jewish school and an Arab school in the Jerusalem area, using an anonymous self-completion questionnaire. A total of 791 questionnaires was analyzed, 479 from the Jewish students and 312 from the Arab students. RESULTS The lowest prevalence of smoking was found among Arab female students and the highest among Jewish female students (9% vs. 41%, P < 0.001). The prevalence of smoking among Jewish and Arab males was similar. More Arab female students smoked than their mothers. Peer pressure seemed to be a more important factor among Jewish students. CONCLUSIONS This study demonstrated the presence of ethnic differences in smoking prevalence and the reasons for smoking among adolescents in Israel. These results suggest the need for specific smoking prevention policies for different ethnic groups.

Abstract
OBJECTIVES We previously noted that white blood cells (WBC) have increased adhesive properties during bacterial infections. Here, we aim to explore the possibility of using the different adhesive properties of WBC as a means of differentiating between viral and bacterial infections, a common problem in paediatrics. METHODS The adhesive properties of WBC in the peripheral blood of 25 children with documented bacterial infections, 15 with documented viral infections and 36 with probable viral infections, were studied by means of a leukocyte adhesiveness/aggregation slide test (LAAT). The results of the LAAT were compared with those of the other acute phase reactants, namely WBC, differential count and erythrocyte sedimentation rate (ESR), which were taken in the same blood sample in each patient. RESULTS The sensitivity, specificity and positive predictive value were 92%, 96%, and 92%, respectively for the LAAT; 83%, 87% and 80% for the ESR; 56%, 78% and 56% for the white blood cell count; and 54%, 74% and 50% for the differential count. CONCLUSIONS The presence of bacterial infections in children can be tested using a simple slide test to reveal the increased state of leukocyte adhesiveness/aggregation in the peripheral blood. The LAAT is a reliable, rapid and inexpensive test, and it can be a useful laboratory tool for the paediatrician treating a child with acute febrile illness.

Abstract
Scientific and expert advisory committees responsible for food products often have the advantage of being relatively unhindered by rigid regulations and the simultaneous disadvantage of having few guidelines to clarify their role in directing the research and approval process. Committees can thus miss opportunities to function in a proactive advisory capacity, and to assist in predetermining what research and documentation are necessary for regulatory approval of a particular food product. This paper examines the ways scientific and expert committees for nutritional products can contribute to formulation of procedures for effective hypothesis and study design development, preparation of well-structured, complete dossiers for product approval, and transparent interactions with petitioners.

Abstract
BACKGROUND Intestinal ischemia-reperfusion (IR) injury results in cell destruction, which may be mediated by the generation of reactive oxygen species, potentially toxic metabolites of xanthine oxidase. Pentoxifylline (PTX) possesses a variety of biochemical and antioxidant properties that can improve capillary flow and tissue oxygenation. Because of these combined effects, it has been hypothesized that pentoxifylline would protect against intestinal IR. METHODS Young adult rats were randomly assigned to one of four experimental groups: IR/Placebo (n = 12) in which superior and inferior mesenteric arteries were clamped for 45 minutes and then reopened; IR/PTX (n = 11) in which IR was induced as in the Placebo group, but with 25 mg/kg PTX at 0, 30, and 60 minutes; No IR/Placebo (n = 12); and No IR/PTX (n = 6) in which placebo and PTX were applied with no IR. Blood and intestinal samples were taken for serial thiobarbituric acid-reducing substances (TBARS; index of lipid peroxidation), for xanthine oxidase-xanthine dehydrogenase ratios, glutathione, myeloperoxidase, and histopathology. RESULTS Animals in the IR/PTX group had lower TBARS and the least severe histopathologic injury. Xanthine oxidasexanthine dehydrogenase ratios were elevated only in IR/ Placebo (0.67+/-0.22 vs. 0.45+/-0.14 in IR/PTX; 0.42+/-0.22 in No IR/Placebo; and 0.40+/-0.11 in No IR/PTX; p = 0.0009). Reduced glutathione was diminished in IR/PTX animals (38.9 +/-1.35 vs. 46.1+/-7.0 in IR/Placebo; 41.1+/-2.5 in No IR/ Placebo; 43.6+/-1.0 in No IR/PTX; p = 0.048). No differences were recorded in myeloperoxidase levels among groups. CONCLUSIONS Pentoxifylline ameliorates histopathologic signs of injury and decreases lipid peroxidation (TBARS). Normal xanthine oxidase-xanthine dehydrogenase ratios in the treated compared with IR-only animals imply that the protective effect of PTX is at least partially mediated through inhibition of xanthine oxidase.

Abstract
STUDY OBJECTIVES The incidence and prevalence of pertussis in adults have increased in recent years. It has been shown that previously immunized adults and adolescents are the main sources of transmission of Bordetella pertussis. The aim of this study was to describe the clinical presentation and the clinical course of pertussis in children and young adults who were immunized previously against B pertussis. DESIGN Retrospective study. SUBJECTS Children and young adults who were reported by local physicians to the Department of Epidemiology in the Israeli Ministry of Health with serologically confirmed pertussis and who were immunized previously were included. Information sought included personal data, epidemiologic data, signs and symptoms, laboratory results, initial diagnosis, and treatment. RESULTS In the 95 previously immunized patients with serologically confirmed pertussis (mean age [+/- SD], 8.9 +/- 4.4 years old; range, 5 to 30 years old), the mean duration from onset of symptoms until the final diagnosis of pertussis was 23 +/- 15 days. The disease was usually atypical and generally mild. All the described patients had cough, usually prolonged, lasting 4 +/- 3.6 weeks. Only 6% had the classic whoop. The mean WBC count was 8.7 +/- 2.6 cells/mm6, and the lymphocyte count was 40 +/- 12%. Two patients were admitted to the hospital for severe pneumonia. Among the reported cases, the proportion of patients between the ages of 10 and 45 years increased from 6.5% during the period from 1971 to 1980, to 26% during the period from 1980 to 1990, and to 38% during a 1989 outbreak. CONCLUSIONS Pertussis in previously immunized individuals is usually characterized by an atypical and relatively mild clinical course. Patients suffer mainly from a prolonged and persistent cough. Early diagnosis may lead to prompt administration of therapy. Prophylaxis of exposed persons might be effective in decreasing both severity and transmission of the disease.

Abstract
BACKGROUND Right lower quadrant abdominal pain may pose a diagnostic problem in patients with cystic fibrosis. Abdominal ultrasound examination, used commonly in the diagnostic work-up, may reveal abnormalities of the appendix. However, interpretation of such findings is problematic, because the appearance of the gastrointestinal system during routine examination has not been documented in patients with cystic fibrosis. The purpose of this study was to investigate the findings during routine abdominal ultrasound scans in our cohort of patients with cystic fibrosis and in control subjects. METHODS Abdominal ultrasound scans were performed prospectively during routine clinic visits in a cohort of patients with cystic fibrosis. RESULTS Fifty patients aged 10+/-6 years, (range, 0.5-28 years) were examined; 45 had pancreatic insufficiency. Four patients (3 with pancreatic insufficiency) reported right lower quadrant pain at the time of the scan. According to standard ultrasound criteria, the appearance of the appendix was abnormal in 8 patients (16%), 6 had a mucoid appendix, and 2 had a pathologically thickened appendiceal wall. Only 1 of these 8 patients mentioned abdominal pain at the time of the study. Other incidental findings included gallstones (3 patients), intussusception (2 patients), and pancreatic cyst (1 patient). CONCLUSIONS Abnormalities can be observed during routine abdominal ultrasonographic studies in cystic fibrosis. These findings may not be associated with abdominal pain; their clinical relevance needs further investigation.

Abstract
OBJECTIVE The aim of this study was to define the role of possible risk factors for the development of cystic fibrosis (CF)-related liver disease and to analyze the association between liver disease and the different genotypes present in the Israeli CF patient population. PATIENTS AND METHODS All patients followed at the seven CF centers in Israel were included in this study. Liver disease was determined by persistently elevated serum liver enzymes and/or bilirubin, and/or significant ultrasonographic changes suggestive of chronic liver disease. The following clinical parameters were evaluated: ethnic origin, age at assessment of liver function, sex, history of meconium ileus, pancreatic function, history of distal intestinal obstruction syndrome, pulmonary function, and cystic fibrosis transmembrane conductance regulator mutation analysis. RESULTS Of the 288 patients screened, 80 (28%) had liver disease. Of the 256 patients with pancreatic insufficiency, 80 (31%) had liver disease compared with none of the 32 patients with pancreatic sufficiency. Genotype-phenotype correlation was performed on 207 patients carrying identified mutations that were previously classified according to phenotype severity. Liver disease was found in 56 (32%) of 173 patients carrying mutations associated with a severe phenotype and in 6 (38%) of 16 patients carrying at least one mutation associated with a variable genotype (G85E and/or 5T allele). None of the 18 patients carrying the 3849+10kb C->T mutation had liver disease. Prevalence of liver disease increased with age. No correlation was found between liver disease and severity of lung disease, nutritional status, history of meconium ileus, or distal intestinal obstruction syndrome. CONCLUSION CF patients who have pancreatic insufficiency and carry mutations associated with a severe or a variable genotype are at increased risk to develop liver disease.

Abstract
BACKGROUND Programmed cell death refers to the genetically determined processes by which cells die in response to physiologic extracellular and intracellular signals, morphologically described as apoptosis. In physiologic and pathologic circumstances this process may involve effector and target cells. METHODS To identify serine esterase granules in intraepithelial lymphocytes, fresh-frozen human small intestine mucosal sections from normal and celiac-affected mucosa were incubated with substrate-specific N-alpha-benzyloxy-carbonyl-L-lysine thiobenzyl (BLT) and a chromogen (4 Benzoylamino-2,5-diethoxybenzene-dazonium chloride hemi [zinc chloride] salt as capture agent and were examined by light microscopy. RESULTS Normal mucosa showed an occasional intraepithelial lymphocyte with BLT-positive intracytoplasmic granules. Some large mononuclear cells of the lamina propria were similarly stained. Many more intraepithelial lymphocytes were BLT-positive among the surface enterocytes of untreated celiac mucosa. Lamina propria mononuclear cells close to the basal layer of crypt cells also appeared to be increased. CONCLUSIONS The histochemical identification of BLT-positive esters within intraepithelial lymphocytes suggests their involvement in enterocyte death under physiologic conditions. The increased BLT-positive intraepithelial lymphocytes found in the celiac mucosa may be related to the known increase in cytotoxic intraepithelial lymphocytes in untreated celiac disease.

Abstract
Corticosteroids continue to be used by many physicians to treat infants with bronchiolitis. The aim of this study was to examine the short-term and long-term efficacy of oral corticosteroid therapy when added to beta2-agonists in infants with mild to moderate bronchiolitis (defined as the first episode of wheezing associated with low grade fever, rhinitis, tachypnea, and increased respiratory effort in a previously healthy infant during the winter months). Infants with mild to moderate bronchiolitis, were randomly assigned to receive either oral prednisone (2 mg/kg/day) or placebo for 3 days. All patients received nebulized albuterol q.i.d. during this period. Upon admission and after 3 days of therapy, a clinical score was assigned based on respiratory rate, use of accessory muscle, and the presence of wheeze. Oxygen saturation (SaO2) was also measured. On day 7, we inquired as to the well-being of each child. Two years later, the development of chronic respiratory symptoms was assessed. Thirty-eight infants were enrolled in the study; 20 received prednisone and 18 received placebo. Both groups were similar in terms of age, duration of illness prior to enrollment, pretrial medication use, clinical severity of bronchiolitis, history of atopy, and family history of atopy. After 3 and 7 days of treatment, both groups showed similar clinical improvement and there were no statistically significant differences between the two groups in the clinical score or in the SaO2. No major side effects were observed. Two years later, 32% of the infants continued to suffer from chronic respiratory symptoms, with a similar prevalence in both groups. We conclude that a 3-day course of oral corticosteroids is of no benefit to infants with mild to moderate bronchiolitis who are also treated with an inhaled beta2-agonist.

Abstract
Gallbladder (GB) abnormalities are rarely reported in children, but involvement of the GB has been demonstrated in various inflammatory disorders. Thirty-nine children hospitalized with hepatitis A virus infection were evaluated by ultrasound. Pseudosurgical gallbladder wall of 10 mm or more with striation was found in 10. Pathological echographic findings were found in the pancreas of three patients, one with frank pancreatitis. Ascitic fluid was noted in eight. Pediatricians and pediatric surgeons alike should be familiar with this gallbladder and pancreatic involvement, which might avoid unnecessary procedures or surgery.

Abstract
During the last decade significant changes have occurred in our concepts of celiac disease. As a result of the implementation of sensitive and specific serologic tests, the epidemiology and clinical presentation of affected patients have been radically reconsidered. Extraintestinal manifestations of celiac disease have been radically reconsidered. Extraintestinal manifestations of celiac disease have been increasingly recognized, and the strict association with diseases recognized as autoimmune disorders is well established; celiac disease itself has many aspects of an autoimmune condition. Celiac disease is of interest to clinicians and scientists because it represents a valuable model for the comprehension of diseases in which environmental, genetic, and immunologic factors interplay.

Abstract
BACKGROUND Concern over the adequacy of histologic diagnosis of endoscopic duodenal biopsies in children prompted this comparative study on the histologic quality of endoscopic versus capsule biopsies. We found this problem addressed in only six previous reports. METHODS Blind examinations of the histologic sections of 48 duodenal biopsies obtained by gastrointestinal endoscopy in children aged 2-18 years were compared to 52 biopsies obtained by the small bowel suction method (from children aged 1-16 years). RESULTS Although 87.5% of endoscopic biopsies and 94.2% of capsule biopsies were adequate for histologic diagnosis, fragmentation or squashing was seen in 83.3% of endoscopic biopsies and only in 25% of capsule biopsies. CONCLUSIONS Biopsies obtained by suction are of better quality than those obtained by endoscopy. If endoscopy is preferred for technical reasons, the following conditions should be observed: the patients should be aged over 2 years, and a minimum of four biopsies should be obtained with forceps of a diameter greater than 2 mm. Adequate histologic criteria for diagnosis should include at least one full-thickness mucosal specimen more than 3 mm in length, vertically oriented, and not fragmented. In children under age 2, duodenal or jejunal capsule biopsies are preferred, since the specimens are usually larger and less fragmented. Endoscopy is technically more difficult in the very young patient.

Abstract
Abstract. Kingella kingae is a fastidious Gram-negative rod that since the 1980s has been appreciated as a cause of a variety of human infections, including bone and joint infections, bacteremia, and rarely endocarditis [2, 6, 7, 9]. K. kingae endocarditis is rare, and only a few cases occur in normal, native valves. We report a case of K. kingae endocarditis in a patient with hair-cartilage hypoplasia who had previously undergone bone marrow transplantation. The combination of these rare conditions is discussed.

Abstract
OBJECTIVE Cystic fibrosis (CF) has variable clinical presentation. Disease severity is partially associated with the type of mutation. The aim of this study was to report genotype-phenotype analysis of the G85E mutation. PATIENTS The phenotype of 12 patients (8 were from the same extended family, and 5 of them were siblings from 2 families) carrying at least one copy of the G85E mutation was evaluated and compared with the phenotype of 40 patients carrying the two severe mutations, W1282X and/or DeltaF508 (group 1), and with 20 patients carrying the splicing mutation, 3849+10kb C->T, which was found to be associated with milder disease (group 2). RESULTS A high phenotypic variability was found among the patients carrying the G85E mutation. This high variability was found among patients carrying the same genotype and among siblings. All the studied chromosomes carrying the G85E mutation had the 7T variant in the polythymidine tract at the branch/acceptor site in intron 8. Of the G85E patients, 25% had pancreatic sufficiency and none had meconium ileus, compared with 0% and 32%, respectively, of patients from group 1, and 80% and 0%, respectively, from group 2. Two patients carrying the G85E mutation had sweat chloride levels <60 mmol/L whereas all the others had typically elevated levels >80 mmol/L. Compared with group 2, patients carrying the G85E mutation were diagnosed at an earlier age and had higher sweat chloride levels, with mean values similar to group 1 but significantly more variable. Forced expiratory volume in 1 second (FEV1) was similar in the three groups, with no differences in the slope or in age-adjusted mean values of FEV1. The levels of transcripts lacking exon 9 transcribed from the G85E allele measured in 3 patients were 55%, 49%, and 35% and their FEV1 values were 82%, 83%, and 50% predicated, respectively. CONCLUSIONS The G85E mutation shows variable clinical presentation in all clinical parameters. This variability could be seen among patients carrying on the other chromosome the same CFTR mutation, and also among siblings. This variability is not associated with the level of exon 9 skipping. Thus, the G85E mutation cannot be classified either as a severe or as a mild mutation.

Abstract
Some patients express various features of cystic fibrosis (CF) even though essential characteristics of the disease might be absent. Such patients may suffer from respiratory disease without pancreatic insufficiency and normal sweat chloride levels. Others may present as male infertility because of congenital bilateral aplasia of the vas deferens (CBAVD) with no other signs of CF. The 5T allele, a DNA variant in a noncoding region of the cystic fibrosis transmembrane conductance regulator (CFTR) gene that reduces the level of the normal CFTR transcripts, was found in increased frequency among male patients with CBAVD. The purpose of this study was to investigate the possibility that the 5T allele is associated with dysfunction of organs other than the male reproductive system, leading to CF or atypical CF. Analysis of the 5T allele was performed on 148 subjects (29 with CF, 61 with atypical CF, and 58 with CBAVD) carrying 232 chromosomes with unidentified CFTR mutations, and on 142 non-CF chromosomes from healthy subjects of Ashkenazi origin. The frequency of the 5T allele among chromosomes from patients of Jewish Ashkenazi origin with CF and atypical CF (six of 33; 18%) was significantly higher than the frequency in the normal Ashkenazi population (eight of 142; 6%; p = 0.03). Analysis of the clinical presentation of the five patients with CF and the 12 patients with atypical CF carrying the 5T allele indicated that most patients suffered from respiratory disease presenting as asthma like symptoms, nasal polyposis, chronic sinusitis, chronic bronchitis, or bronchiectasis. Six patients had pancreatic insufficiency, two with meconium ileus. Sweat Cl- levels ranged from normal to elevated. Of the six male patients with respiratory disease who were old enough to be evaluated for fertility status, five were fertile and one had pancreatic insufficiency. Among male patients with CBAVD, 41% suffered from respiratory symptoms. Thus, the 5T allele is a variant with partial penetrance causing disease with an extreme variability of clinical presentation: from normal healthy fertile subjects or male patients with CBAVD to those with atypical or typical clinical phenotype of CF.

Abstract
STUDY OBJECTIVE Cigarette smoking is a major preventable cause of morbidity and mortality worldwide. Most adult smokers start smoking regularly some time before 18 years of age. The aim of this study was to determine the age at which children begin cigarette smoking, to study the environmental factors that influence children to smoke, and to understand the reasons why children smoke. The results of this study may help lead to the development of more effective smoking prevention programs. METHODS We carried out a cross-sectional survey of all students in grades 6 to 11 (ages: 11 to 17 years) in two high schools in the Jerusalem area, using an anonymous self-completion questionnaire. The students were asked questions regarding the age at which they began smoking, initiation, their smoking habits, their reasons for smoking, and their views on children who smoke. In addition, they were asked about the smoking status of their parents, siblings, and friends. Finally they were asked about the health hazards of smoking. RESULTS Of the 847 students who answered the questionnaire, 35% stated that they had smoked at least once and 14% stated that they were currently smoking. The percentage of students who were currently smoking increased gradually with age to 36%. There was a sharp increase in experimental smoking after seventh grade (ages 12 to 13 years). Having a friend who smoked substantially increased the likelihood of smoking, whereas parental smoking or having a sibling who smoked did not increase the likelihood of smoking. The most common reason for starting to smoke was "to try something new" (55%). There was a significant difference between the views of students with different smoking statuses regarding children who smoke: nonsmoking children associated more negative characteristics to smoking. All of the children studied were well aware of the health hazards of cigarette smoking. CONCLUSIONS Smoking is highly prevalent among schoolchildren in Jerusalem. The increase in the rate of smoking at the age of 12 years indicates that smoking prevention programs need to be started at an earlier age. Peer pressure is a very strong stimulus for smoking in children. Since children are aware of the health hazards of smoking, prevention policy should be aimed more at associating smoking with negative images and addressing peer pressure.
