Abstract
BACKGROUND The relationship of airway hyperresponsiveness to airway remodeling and inflammation in infants with wheeze is unclear. OBJECTIVE To investigate airway hyperresponsiveness, remodeling and inflammation in infants with wheeze and troublesome breathing. METHODS Inclusion criteria were as follows: full-term, 3-23 months of age; doctor -diagnosed wheeze and persistent recurrent troublesome breathing; without obvious structural defect, suspicion of ciliary dyskinesia, cystic fibrosis, immune deficiency or specified use of corticosteroids. Airway hyperresponsiveness (AHR) was evaluated by performing a methacholine bronchial challenge test combined with whole body plethysmography and rapid thoracoabdominal compression. Endobronchial biopsies were analysed for remodeling (thickness of reticular basement membrane and amount of airway smooth muscle) and for inflammation (numbers of inflammatory cells). Correlation analyses were performed. RESULTS Forty-nine infants fulfilled the inclusion criteria for the present study. Median age was 1.06 years (IQR 0.6; 1.5). Lung function was impaired in 39/49 (80%) children, at the median age of 1.1 years. Methacholine challenge was successfully performed in 38/49 children. Impaired baseline lung function was correlated with AHR (P = .047, Spearman). In children with the most sensitive quartile of AHR, the percentage of median bronchial airway smooth muscle % and the number of bronchial mast cells in airway smooth muscle were not significantly higher compared to others (P = .057 and 0.056, respectively). No association was found between AHR and thickness of reticular basement membrane or inflammatory cells. Only a small group of children with both atopy and AHR (the most reactive quartile) had thicker airway smooth muscle area than non-atopics with AHR (P = .031). CONCLUSIONS AND CLINICAL RELEVANCE These findings do not support the concept that AHR in very young children with wheeze is determined by eosinophilic inflammation or clear-cut remodeling although it is associated with impaired baseline lung function. The possible association of increased airway smooth muscle area among atopic children with AHR remains to be confirmed.

Abstract
BACKGROUND Associations between early deficits of lung function, infant airway disease, and outcome at school age in symptomatic infants are still unclear. OBJECTIVE To report follow-up data on a unique cohort of children investigated invasively in infancy to determine predictive value of airway disease for school-aged respiratory outcomes. METHODS Fifty-three infants previously studied using bronchoscopy and airway conductance were approached at 8 years of age. Symptoms, lung volumes, and airway responsiveness were reassessed. Data on lifetime purchase of asthma medication were obtained. Lung function was compared with that of 63 healthy nonasthmatic children. RESULTS Forty-seven children were reevaluated. Physician-diagnosed asthma was present in 39 children (83%). Twenty-five children (53%) had current and 14 children (30%) had past asthma. No pathologic feature in infancy correlated with any outcome parameter. As expected, study children had significantly reduced lung function and increased airway responsiveness compared with healthy controls, and very early symptoms were risk factors for reduced lung function. Current asthma was associated with reduced infant lung function and parental asthma. Reduced lung function in infancy was associated with purchase of inhaled corticosteroids when 6 to 8 and 0 to 8 years of age. CONCLUSION The lack of predictive value of any pathologic measure in infancy, reported here for the first time to our knowledge, demonstrates that pathologic processes determining the inception of asthma, which are as yet undescribed, are different from the eosinophilic inflammation associated with ongoing disease.

Abstract
BACKGROUND Few data are available about the inflammatory cytokine profile of bronchoalveolar lavage (BAL) from young children with frequent wheeze. The first aim was to investigate the BAL cellular and cytokine profiles in infants with recurrent lower respiratory symptoms in whom bronchoscopy was indicated for clinical symptom evaluation. The second aim was to relate the BAL results with the histological findings of the endobronchial carina biopsies. METHODS Thirty-nine infants (median age 0.9 years) underwent lung function testing by whole-body plethysmography prior to the bronchoscopy. The BAL differential cell counts and cytokine levels were quantified. These findings were compared with the histological findings of the endobronchial carina biopsies. RESULTS The differential cytology reflected mainly that described for healthy infants with lymphocyte counts at the upper range level. A positive association between BAL CD8+ lymphocytes and neutrophils and endobronchial reticular basement membrane was found. Detectable levels of pro-inflammatory cytokine proteins IL-1β, IL-17A, IL-18, IL-23, and IL-33 were found, whereas levels of Th2-type cytokine proteins were low. Frequent wheeze was the only clinical characteristic significantly related to detectable combined pro-inflammatory cytokine profile. Lung function did not correlate with any cytokine. CONCLUSIONS A positive association between BAL CD8+ lymphocytes and neutrophils and endobronchial reticular basement thickness was found. Detectable production of pro-inflammatory cytokines associated positively with frequent wheeze.

Abstract
OBJECTIVE Few reports on choledochal malformations (CMs) in European populations exist. MATERIALS AND METHODS The medical records of pediatric CM patients managed in our nationwide referral center for pediatric hepatobiliary surgery between 1976 and 2013 (n = 38; 71% females) were reviewed. RESULTS Over follow-up time, the relative proportion of fusiform CMs increased significantly (p = 0.007) and the estimated total incidence rose from 1:128,000 to 1:38,000 (p = 0.017). Cystic CMs (42%) presented at younger age than fusiform CMs (47%) (0.8 vs. 4.6 years, p = 0.001). Two-thirds had abdominal pain and half were cholestatic at presentation. Pancreatitis had occurred in 16%. In addition to ultrasound, 71% underwent magnetic resonance cholangiopancreatography and 39% underwent endoscopic retrograde cholangiopancreatography. Median CM dilatation was 15 (10-28) mm and a 12 (9-13) mm long common pancreaticobiliary channel was confirmed in 61%, increasingly during recent years. Intrahepatic biliary tree was dilated in 19%, whereas main ducts were dilated in 50%. Apart from two operated in the 1970s and one with choledochocele, patients underwent resection of extrahepatic bile ducts with Roux-en-Y hepaticojejunostomy at age of 4.2 (0.8-9.2) years. Postoperative bile leakage and hemorrhage required reoperations in two. At last follow-up 4.8 (1.3-13.2) years postoperatively, none had dilated intrahepatic biliary ducts or elevated plasma bilirubin (5 [3-7] µmol/l). Single cholangitis episodes had occurred in two, whereas others were asymptomatic. CONCLUSION CM incidence has increased significantly in Finland, being currently over threefold higher than previous estimates in the Western world would suggest. Removal of the extrahepatic biliary tree with hepaticojejunostomy for type I and IV CMs yielded excellent results.

Abstract
OBJECTIVES To analyse retrospectively population-based results of congenital tracheal stenosis (CTS) repair in infants in Finland. METHODS Data on infants who were operated on for CTS in Helsinki Children's Hospital between August 1988 and May 2013 were analysed retrospectively. Fibreoptic bronchoscopy was performed perioperatively and in follow-up of all the surviving patients. The median follow-up time was 7 (range 1-20) years. RESULTS Thirteen infants were operated on for CTS. Resection of the stenotic segment with individually tailored anastomosis was used in 12 patients and slide tracheoplasty in 1 patient. The median age at the operation was 2.9 (range 0.2-19) months. Eight (62%) patients had associated cardiovascular defects, which were corrected during the same operation. The median length of stenosis was 35% (range 25-60%) of the total length of the trachea. The median length of time of postoperative mechanical ventilation was 10 (range 5-19) days. The median length of time of intensive care treatment was 15 (range 7-40) days. One patient died from hypoplastic lung tissue and fibrosis, and multiorgan failure. One patient required reoperation, and 3 other patients received balloon bronchodilatations postoperatively. There was no late mortality. All of the 12 survivors had a good outcome. CONCLUSION Resection with individually tailored anastomosis with up to 55% of the stenotic segment of the trachea presented a good long-term outcome.

Abstract
The American Academy of Pediatrics recently released its new Technical Report and Policy Statement on male circumcision, concluding that current evidence indicates that the health benefits of newborn male circumcision outweigh the risks. The technical report is based on the scrutiny of a large number of complex scientific articles. Therefore, while striving for objectivity, the conclusions drawn by the 8 task force members reflect what these individual physicians perceived as trustworthy evidence. Seen from the outside, cultural bias reflecting the normality of nontherapeutic male circumcision in the United States seems obvious, and the report's conclusions are different from those reached by physicians in other parts of the Western world, including Europe, Canada, and Australia. In this commentary, a different view is presented by non-US-based physicians and representatives of general medical associations and societies for pediatrics, pediatric surgery, and pediatric urology in Northern Europe. To these authors, only 1 of the arguments put forward by the American Academy of Pediatrics has some theoretical relevance in relation to infant male circumcision; namely, the possible protection against urinary tract infections in infant boys, which can easily be treated with antibiotics without tissue loss. The other claimed health benefits, including protection against HIV/AIDS, genital herpes, genital warts, and penile cancer, are questionable, weak, and likely to have little public health relevance in a Western context, and they do not represent compelling reasons for surgery before boys are old enough to decide for themselves.

Abstract
OBJECTIVE We aimed to study the voice, voice-related quality of life (VRQoL) and health-related quality of life (HRQoL) of children who in early infancy underwent a laryngeal split (cotton plasty operation) at the Helsinki University Central Hospital between January 1990 and December 2005. METHODS A retrospective review identified 17 children, of whom 10 fulfilled the inclusion criteria and participated in the study. Age- and gender-matched volunteers formed a control group. We used generic 16D and 17D questionnaires to assess HRQoL; the Pediatric Voice Outcomes Survey (PVOS) and the pediatric voice-related quality of life (PVRQoL) instrument served to assess VRQoL. The children underwent indirect laryngoscopy and perceptual voice assessment. RESULTS HRQoL and PVRQoL scores did not differ between subjects and controls. The subjects had lower PVOS scores than did the controls (P<0.01). Perceptual assessment revealed that the subjects' voices were worse off according to the following dimensions: voice is strained, voice is hoarse or husky, and voice is weak/does not resonate (P<0.05). CONCLUSIONS This study adds to the knowledge on the long-term effects of laryngeal split on children through assessment of their HRQoL and PVRQoL. The study subjects' lower PVOS scores and findings of perceptual assessment point to the effect of cotton plasty on VRQoL and voice.

Abstract
BACKGROUND Relationships between early deficits of lung function, infant airway pathology and outcome in symptomatic infants are unclear. A study was undertaken to determine the associations between early lung function, airway histology and inflammation in symptomatic infants with the continuance of respiratory symptoms, lung function and subsequent use of inhaled asthma medication at the age of 3 years. METHODS 53 children who underwent lung function measurements and bronchoscopy following referral to a specialist children's hospital for recurrent lower respiratory symptoms at a mean age of 1 year were followed up at 3 years of age. Assessments were made of respiratory symptoms during the previous year, lung function by oscillometry and atopy by skin prick testing. Individual data on the purchase of asthma medications were obtained from the Social Insurance Institution for the 12 months preceding the follow-up visit. RESULTS 50 children (94%) were re-evaluated, of whom 40 had ongoing airway symptoms. 11/39 (28%) who underwent successful oscillometry had reduced lung function, 31/50 (62%) used inhaled corticosteroids (ICS) regularly and 12/50 (24%) used ICS intermittently. Abnormal lung function at infancy was associated with ongoing airway symptoms (p<0.001) and with the purchase of ICS (p=0.009) and β agonists (p=0.002). Reticular basement membrane thickness in infancy and the numbers of mucosal mast cells, but not eosinophils, correlated significantly with the amount of ICS purchased at 3 years (p=0.003 and p=0.018, respectively). CONCLUSIONS Reduced lung function, thickening of the reticular basement membrane and increased density of mucosal mast cells in infancy are associated with respiratory morbidity and treatment needs at age 3 years in this highly selected group of children.

Abstract
OBJECTIVE Esophageal atresia (EA) predisposes to gastroesophageal reflux that is associated with intestinal metaplasia and may result in development of adenocarcinoma of the esophagus. To date, the literature has reported 5 cases of esophageal cancer in adult patients treated for EA. The aim of this study was to find out the incidence of esophageal cancer in adult patients with repaired EA. PATIENTS AND METHODS Five hundred two consecutive patients treated for EA from 1949 to 1978 were followed-up for cancer through the files of the population-based countrywide cancer registry from 1967 to 2004. The number of cancer cases observed and person-years at risk were counted, and the expected number of cancer cases estimated from the national cancer incidence rates. The standardized incidence ratios (SIRs) were calculated by dividing the number of cancer cases observed by the expected numbers. RESULTS None of the 502 patients were lost to follow-up; 230 patients who died before 1967 younger than the median age of 8 days were excluded from further analysis. The 272 remaining patients (142 males) were eligible for follow-up (median age, 35 years; range, 2 days to 56 years). Three cases of cancer were found (SIR, 1.0; 95% confidence interval, 0.20-2.8). One was lymphoma in small intestine, 1 was leukemia, and 1 carcinoma of the uterus but no cases of esophageal cancer. CONCLUSIONS Our study is able to exclude long-term risk for esophageal cancer after repair of EA 500-fold higher than that of the normal population. Considering the relatively young age of the survivors, further studies and continued follow-up are warranted to elucidate risk for esophageal cancer and need for endoscopic surveillance after repair of EA.

Abstract
BACKGROUND In early childhood, the ability to mount protective immune responses in the airways is impaired, with increased risk of allergic sensitisation to inhaled allergens. Antigen presenting cells (APC) and regulatory T cells (Treg) are important modifiers of T cell immunity but little is known about their distribution in bronchial mucosa at this age. Here the subset distribution of APC and the appearance of Foxp3(+) Treg and bronchus associated lymphoid tissue (BALT) were examined immunohistochemically in children less than 2 years of age with chronic asthma-like symptoms of the lower airways. METHODS Immunophenotyping was performed in situ on bronchial biopsy specimens obtained from 45 infants, 4-23 months of age, under investigation for airway disease. RESULTS A well developed HLA-DR(+) network of APC was present in all samples, approximately 50% of the cells being CD68(+) macrophages and the remainder various subsets of dendritic cells. The density of HLA-DR(+) cells increased significantly with age but was not related to atopy, clinical symptoms or lung function. Comparing the density of APC subsets and clinical parameters, only the number of intraepithelial CD1a(+) dendritic cells was significantly increased in infants who had recently suffered a respiratory infection. BALT structures were identified in 22 children, with no relation to lung function, atopic status or human rhinovirus positivity. Plasmacytoid dendritic cells and Foxp3(+) Treg were located primarily within these isolated lymphoid follicles. CONCLUSION A bronchial network of dendritic cells and macrophages develops quite rapidly after birth, apparently independent of clinical symptoms or atopy. The high frequency of BALT structures containing putative tolerogenic dendritic cells and Treg suggests that these lymphoid follicles play an important role in bronchial immune homeostasis during infancy.

Abstract
Before the closure of an enterostomy, a distal loop contrast radiograph (DLCR) is widely used to disclose pathology which may affect the performance of the procedure. We studied whether DLCR of paediatric patients caused actual alterations in the surgical plan and whether it predicted postoperative complications. Between 1991 and 2006, 105 patients (small bowel enterostomy, SBE; n = 51), (colostomy, CO; n = 54) underwent closure of an enterostomy. All 105 patients had preoperative DLCR. The indications for enterostomy included anorectal malformation (n = 38), neonatal intestinal perforation (n = 25), J-Pouch ileoanal anastomosis (n = 20), anorectal trauma (n = 5), and miscellaneous (n = 17). We recorded sensitivity, specificity, and positive and negative predictive value (PPV and NPV) of DLCR for complications within 6 postoperative weeks. DLCR was considered complete and interpreted as normal in 94 (90%) and abnormal (incomplete n = 3 or pathological n = 8) in 11 (10%) patients. None of the 11 abnormal findings caused cancellation of surgery, but in three (27%) patients it was possible to surgically correct a stricture seen in DLCR. The frequency of surgical complications was 17/105 (16%), SBE (15/51,29%) and CO (2/54, 4%), (P < 0.05). Most common complications (9/17, 53%) were those associated with the intestinal anastomosis. For postoperative complications DLCR had sensitivity, specificity, and PPV and NPV of 47, 97, 73 and 90% (SBE and 47, 97, 88 and 81%), (CO 50, 96, 33 and 98%). The pathology seen in DLCR, however, seldom directly hinted the complications which actually occurred. Abnormal DLCR changed the surgical plan in less than one-fifth of the cases. For surgical complications DLCR had poor sensitivity, good specificity and NPV, and moderate PPV. The pathology suggested by DLCR, however, correlated poorly with the actual complications. Poor sensitivity reflects the high frequency of anastomotic complications, which are practically unpredictable by preoperative radiographs.

Abstract
A rare but serious adverse event of total hip replacement (THR) is periprosthetic femoral fracture. The aim of the present study was to assess whether there was an excess mortality due to such a fracture and to estimate the probability of death caused by the fracture. We studied primary total hip replacement in 27,652 men and 35,930 women with osteoarthritis from The Swedish National Hip Arthroplasty Register operated from 1979 to 2000. From the same register we also studied 392 men and 344 women with periprosthetic fracture from 1979 to 2000, all with osteoarthritis as the primary diagnosis. By the special method applied, it was possible to perform the estimation of death due to the fracture event though we could not determine in the individual case whether the fracture caused the death. Compared to the total population of patients operated with a primary THR there was a higher mortality rate immediately after the surgery for patients with periprosthetic fracture and in the longer run for patients below the age of 70 years. At the age of 70 years the estimated probability of death due to the fracture was 2.1% for men and 1.2% for women. At the age of 80 years at fracture the corresponding probabilities were 3.9% and 2.2% for men and women, respectively.

Abstract
BACKGROUND Functional outcomes after treatment of low anorectal anomalies remain controversial. To address this, we conducted a controlled, prospective single-center long-term follow-up study of functional outcome in boys treated for perineal fistula with anoplasty. PATIENTS AND METHODS Twenty-four consecutive boys treated exclusively for perineal fistula from 1992 to 2001 underwent prospective follow-up after completion of toilet training. All of the patients had identical surgical treatment. Functional outcome was assessed according to a previously validated bowel function score (7 questions, maximum score of 20). Daytime and nighttime wetting, as well as the age at toilet training, were also recorded. Thirty-seven age-matched boys served as healthy controls. An independent nurse specialist interviewed caregivers. RESULTS Age of the patients (9.1 +/- 2.6 years) and controls (9.0 +/- 2.9 years) were similar. Seven patients (32%) had bowel function scores below the 10th percentile (17.2) of the controls, which was chosen as a lower limit of normality. The overall mean bowel function score was significantly lower (P < 0.01) among the patients (17.9 +/- 1.9) compared with the controls (19.1 +/- 1.2). The difference was attributed mainly to significantly lower scores (0-3) among patients in questions assessing constipation (2.4 +/- 0.8 vs 2.9 +/- 0.3; P < 0.05) and soiling (2.5 +/- 0.5 vs 2.8 +/- 0.4; P = 0.05). Constipation and soiling were significantly more common (P < 0.05) among patients (41% and 55%, respectively) compared with controls (8% and 24%, respectively). CONCLUSIONS Overall long-term bowel function is impaired in one third of boys with perineal fistula. The main reasons for impaired functional outcome are constipation and soiling, which affect as many as half the patients.

Abstract
BACKGROUND Human rhinoviruses (HRVs) are a common cause of upper respiratory tract infections. There is growing evidence that HRVs are also important in lower respiratory tract infections and often induce asthma exacerbations. OBJECTIVE We evaluated the presence of HRV in the lower respiratory tract by obtaining bronchial biopsies from infants with recurrent asthmalike respiratory symptoms. METHODS A total of 201 steroid-naive infants age 3 to 26 months with recurrent respiratory symptoms for at least 4 weeks within the preceding 2 months were studied for lung function using body plethysmography. Bronchoscopy was performed in 68 children, and bronchial biopsies were available from 59 infants for HRV detection with in situ hybridization. RESULTS Human rhinovirus was detected in 21 of 47 (45%) specimens. Abnormal lung function (decreased airways conductance) was found in 18 of 21 (86%) HRV(+) infants and in 15 of 26 (58%) HRV(-) infants (P = .037). Occurrence of a respiratory infection in the 6 weeks preceding bronchoscopy correlated with HRV positivity (P = .036). CONCLUSION Human rhinovirus is frequently found in the lower airways in infants with recurrent respiratory symptoms, and the majority of these HRV(+) infants also showed increased airway resistance. CLINICAL IMPLICATIONS Human rhinovirus is a common pathogen causing upper and lower respiratory symptoms. Follow-up of these infants will reveal whether the presence of HRV in the bronchial biopsy and abnormal lung function with recurrent respiratory symptoms predicts subsequent asthma.

Abstract
OBJECTIVE Fecal calprotectin is a promising marker for the assessment of gastrointestinal inflammation. Fecal calprotectin levels were followed-up in children with inflammatory bowel disease (IBD) who were introduced to glucocorticoid therapy. The aim of this study was to assess whether the changes in fecal calprotectin levels reflect therapeutic responses. MATERIAL AND METHODS Fecal calprotectin was measured by enzyme immunoassay in 57 children (mean age 9.8 years, range 0.9-18 years) who underwent colonoscopies (IBD n=31, non-IBD disease n=13, normal n=13) and followed-up in 15 children (mean age 13 years, range 3.6-18 years) who were introduced to glucocorticoid therapy because of active IBD at 0, 2, and 4 weeks and at 4-week intervals until one month after discontinuation of the therapy. RESULTS Fecal calprotectin was <100 microg/g in 70% of the children with normal findings on colonoscopy or a non-IBD disease. Fecal calprotectin was >100 microg/g in all but one child with active IBD and in 13/15 of those children who were introduced to glucocorticoids by the clinicians. Fecal calprotectin values decreased within 4 weeks in line with clinical improvement in 7 children and normalized in 4/15 children during the follow-up. Fecal calprotectin increased in 5/8 of the non-steroid-dependent children after discontinuation of glucocorticoids. CONCLUSIONS Fecal calprotectin is a sensitive marker for chronic colitis. In active disease treated with glucocorticoids, fecal calprotectin levels declined in line with the clinical improvement but seldom fell within the normal range, which suggests ongoing inflammation in a clinically silent disease. The measurement of fecal calprotectin may provide new tools for the assessment of the level of gut inflammation in children with chronic colitis in the follow-up of clinical responses.

Abstract
Periprosthetic fracture of the femur is an uncommon complication after total hip replacement, but appears to be increasing. We undertook a nationwide observational study to determine the risk factors for failure after treatment of these fractures, examining patient- and implant-related factors, the classification of the fractures and the outcome. Between 1979 and 2000, 1049 periprosthetic fractures of the femur were reported to the Swedish National Hip Arthroplasty Register. Of these, 245 had a further operation after failure of their initial management. Data were collected from the Register and hospital records. The material was analysed by the use of Poisson regression models. It was found that the risk of failure of treatment was reduced for Vancouver type B2 injuries (p = 0.0053) if revision of the implant was undertaken (p = 0.0033) or revision and open reduction and internal fixation (p = 0.0039) were performed. Fractures classified as Vancouver type B1 had a significantly higher risk of failure (p = 0.0001). The strongest negative factor was the use of a single plate for fixation (p = 0.001). The most common reasons for failure in this group were loosening of the femoral prosthesis, nonunion and re-fracture. It is probable that many fractures classified as Vancouver type B1 (n = 304), were in reality type B2 fractures with a loose stem which were not recognised. Plate fixation was inadequate in these cases. The difficulty in separating type B1 from type B2 fractures suggests that the prosthesis should be considered as loose until proven otherwise.

Abstract
BACKGROUND/PURPOSE Mutations of the RET proto-oncogene are responsible for the development of inherited multiple endocrine neoplasia type 2 and familial medullary thyroid carcinoma (MTC). RET mutations are encountered in patients with Hirschsprung's disease (HD). We hypothesized that the incidence of MTC is increased in patients with HD. METHODS Patients treated for HD at the Children's Hospital, University of Helsinki, during 1939 and 1986 were surveyed for cancer using the population-based countrywide Finnish Cancer Registry from 1967 to 2000. The number of observed cancer cases and that of person-years at risk were counted. The expected number of cancer cases was extrapolated from national cancer incidence rates. To calculate the standardized incidence ratios (SIRs), the observed number of cancer cases was divided by the expected number of cancer cases. RESULTS One hundred fifty-six patients (132 males) with HD were identified. The mean length of patient follow-up was 30.9 years. Seven cases of cancer were observed (SIR, 3.5; 95% CI, 1.4-7.3). Two patients developed MTC (SIR, 550; 95% CI, 67-2000). The cases of MTC occurred in male patients at the ages of 34 and 37 years. No patient developed pheochromocytoma. CONCLUSIONS In this study, we report for the first time an increased risk of MTC occurring in patients treated for HD. The increased risk may be attributed to mutations of the RET proto-oncogene shared by MTC and HD. These findings warrant further studies concerning screening for MTC-type RET mutations in patients with HD.

Abstract
BACKGROUND AND AIM Long-term respiratory, gastrointestinal, and vertebral sequelae are common after repair of congenital diaphragmatic defects (CDDs). The aim of this study was to assess the effect of these sequelae on the health-related quality of life (HRQoL) of adult survivors after CDD repair. MATERIALS AND METHODS A questionnaire, including 36-Item Health Survey Form (SF-36), 36-item Gastrointestinal Quality of Life Index (GIQLI), 55-item Psychosocial Survey, 9-item survey for Respiratory Symptoms-Related Quality of Life Index, and a symptoms query, was sent to 94 adult survivors of CDD and to 400 healthy control subjects. One SD lower than the age-adjusted national average in the 36-Item Health Survey Form score for physical or mental health was considered as low HRQoL. RESULTS Sixty-nine patients with CDD (72%) and 162 (41%) control subjects returned the questionnaire. The initial presentation was critical in less than 10% of patients with CDD. Forty-five patients with diaphragmatic hernia had primary closure; in 1 patient with diaphragmatic hernia, a patch was used. Twenty-four patients had plication of diaphragmatic eventration. The incidence of gastroesophageal reflux (20% vs 2%), recurrent intestinal obstruction (7% vs 0%), and recurrent abdominal pain (12% vs 2%) was significantly higher in patients with CDD than in control subjects, whereas no difference in the incidence of respiratory, musculoskeletal, or other health problems not associated with CDD was found. Scores in GIQLI, Psychosocial Survey, and Respiratory Symptoms-Related Quality of Life Index did not differ between patients with CDD and control subjects. Health-related quality of life was low in 17 (25%) of 69 patients with CDD, which exceeded 1.5 times the expected value. There was no correlation between the type or severity of the primary defect and HRQoL at the time of the study. CONCLUSION Most adults with repaired CDD have good or satisfactory HRQoL. Congenital diaphragmatic defect-associated symptoms with or without acquired diseases significantly impair HRQoL in one fourth of the patients.

Abstract
RATIONALE We hypothesized that the epithelial reticular basement membrane (RBM) thickening and eosinophilic inflammation characteristic of asthma would be present in symptomatic infants with reversible airflow obstruction. METHODS RBM thickness and numbers of inflammatory cells were determined in ultrathin sections of endobronchial biopsies obtained from 53 infants during clinical bronchoscopy for severe wheeze and/or cough. Group A: 16 infants with a median age of 12 months (range 3.4-26 months), with decreased specific airway conductance (sGaw) and bronchodilator reversibility; Group B: 22 infants with a median age of 12.4 months (5.1-25.9 months), with decreased sGaw but without bronchodilator reversibility; and Group C: 15 infants with a median age of 11.5 months (3.4-24.3 months) with normal sGaw. Additional comparisons were made with the following groups. Group D: 17 children, median age 10.3 years (6-16 years), with difficult asthma; Group E: 10 pediatric control subjects without asthma, median age 10 years (6-16 years); and Group F: nine adult normal, healthy control subjects, median age 27 years (21-42 years). MAIN RESULTS There were no significant differences in RBM thickness or inflammatory cell number between the infant groups. RBM thickness was similar in the infants and Groups E and F. However, the RBM in all infant groups (Group A: median 4.3 microm [range 2.8-9.2 microm]; Group B: median 4.15 microm [range 2.7-5.8 microm]; Group C: median 3.8 microm [range 2.7-5.5 microm]) was significantly less thick than that in the older children with asthma (Group D: median 8.3 microm [range 5.3-12.7 microm]; p < 0.001). CONCLUSION RBM thickening and the eosinophilic inflammation characteristic of asthma in older children and adults are not present in symptomatic infants with reversible airflow obstruction, even in the presence of atopy.

Abstract
Anal internal sphincter achalasia is a rare cause of refractory constipation. It is usually treated by internal sphincter myectomy (ISM). The aim of this study was to evaluate the long-term outcome of patients who had undergone ISM for internal sphincter achalasia. Bowel habits, fecal continence, and quality of life were evaluated using a questionnaire. Fecal continence was quantitatively assessed by a score described by Holschneider. A questionnaire was sent to 13 patients (11 male, two female) operated on by ISM for intractable constipation caused by internal sphincter achalasia between 1983 and 1993. Ten patients responded and were included in the study. At the time of the study, three of the 10 patients required oral medication for constipation and had one to three bowel movements per week. One of the 10 patients had three to five bowel movements per day, and the others had one to two bowel movements per day. Four patients had normal and six patients had good continence scores. Four of the patients reported mild social problems, and one had problems associated with sports. Refractory constipation in the majority of patients with internal sphincter achalasia can be treated by ISM. However, in the long term, a significant number of patients suffer from soiling-related social problems.

Abstract
BACKGROUND/PURPOSE Long-term sequelae caused by associated anomalies or respiratory and gastrointestinal disorders are common after the repair of esophageal atresia (EA). The aim of this study was to assess the effect of these sequelae on the health-related quality of life (HRQoL) of patients with EA. METHODS A questionnaire including a 36-item Gastrointestinal Quality of Life Index, a 15-item Respiratory Symptoms-Related Quality of Life Index, and a 36-item psychosocial survey and a symptoms query was sent to 159 patients with EA with or without tracheoesophageal fistula (TEF), who were operated on between 1949 and 1979, and to 400 healthy control subjects. A 36-item Health Survey Form was sent to patients with EA only and the results were compared with values of the general Finnish population. RESULTS A total of 128 patients with EA (80%) and 162 control subjects (41%) returned the questionnaire. Median age [patients with EA, 38 (range, 24-54) years; control subjects, 36 (20-56) years] and sex distribution (M/F of patients with EA, 57:70; control subjects, 63:99) were comparable. Of the 128 patients, 115 (91%) had EA with a distal TEF, 8 (6%) had EA without TEF, 3 (2%) had EA with proximal and distal TEF, and 2 (1%) had TEF without EA. The types of esophageal repair were distributed as follows: primary end-to-end anastomosis (n = 112), colon interposition (n = 10), gastric tube (n = 3), thoracic skin tube (n = 1), and fistula closure only (n = 2). Thirty-eight patients had significant associated anomalies. Gastrointestinal Quality of Life Index scores did not differ statistically between patients with EA and control subjects. However, the incidence of regurgitation (17% vs 10%) and dysphagia (10% vs 2%) was significantly higher in patients with EA (P < .5). Low Respiratory Symptoms-Related Quality of Life Index was found in 10 of 128 patients with EA and in 3 of 163 control subjects (P < .05). Psychosocial survey scores and the incidence of acquired diseases did not differ between the groups (P = NS). The 36-item Health Survey Form indicated low HRQoL in 19 (15%) of patients with EA (expected value, 16%). Of the 19 patients with EA with low HRQoL, 8 (42%) had significant congenital or EA-associated diseases and 11 (58%) had acquired diseases. The type of EA or esophageal conduit was not related to HRQoL. CONCLUSIONS Most adult survivors of EA or TEF repair have a normal quality of life. Morbidity from esophageal functional disorders and respiratory disorders with or without acquired diseases impairs HRQoL in 15% of patients with EA.

Abstract
BACKGROUND/PURPOSE The aim of this study was to determine whether routine dilatation of the anastomosis after repair of an esophageal atresia with distal fistula (EADF) is superior to a wait-and-see policy with dilatation only when symptoms arise. METHODS The records of 100 consecutive patients operated on for EADF in 2 European pediatric surgical centers (A [n = 63], B [n = 37]) were reviewed. In center A, dilatation of the anastomosis was carried out in symptomatic cases only, whereas in center B dilatation was begun 3 weeks postoperatively and repeated every 1-3 weeks until a stable diameter of 10 mm was reached. Particular attention was paid to the number of dilatations per patient, dilatation-related complications, and differences in results after 2 years. RESULTS The patient materials of both centers did not differ with respect to the incidence of prematurity, tracheomalacia, gastroesophageal reflux (GER), and major postoperative complications. The incidence of associated anomalies was higher in center B (P < .05). In center A, 26 of 63 patients underwent dilatation; in center B, all 37 patients were dilated (P < .05). Median number of dilatations per patient was 4 in center A and 7 in center B (P < .05). In center A, 23 of 26 and in center B, 20 of 37 of the patients received medical treatment for GER at the time of the dilatations. Dilatation-related complications developed in 7 of 26 patients of center A and in 3 of 37 patients in the center B (P value, not significant). The median primary hospital stay was 24 days in center A and 33 days in center B (P < .05), median secondary hospital stay for dilatation was 6 days in center A and 13 days in center B (P < .05). After 2 years of follow-up, the incidence of dysphagia, respiratory problems, or bolus obstruction did not differ significantly between the 2 centers. CONCLUSIONS A wait-and-see policy and dilatations based on clinical indications for patients with repaired EADF is superior to routine dilatations. It appears that more than half of the patients do not require dilatations at all.

Abstract
BACKGROUND/AIMS Adult-type hypolactasia (primary lactose malabsorption) affects most of world's human population and limits the use of fresh milk due to lactose intolerance. The diagnosis of adult-type hypolactasia has been difficult to establish because of unsatisfactory diagnostic methods. C/T(-13910) single nucleotide polymorphism residing 13910 base pairs from the 5' end of the lactase gene has been shown to be associated with lactase persistence. The aim of the study was to assess the applicability of the C/T(-13910) variant as a diagnostic test for adult-type hypolactasia during childhood. METHODS Intestinal biopsies were obtained from 329 children and adolescents of African, Finnish, and other White origins aged 0.1-20 years undergoing upper gastrointestinal endoscopy because of abdominal complaints. The biopsies were assayed for lactase, sucrase, and maltase activity and genotyped for the C/T(-13910) variant using polymerase chain reaction minisequencing. RESULTS The frequency of the C/C(-13910) genotype defining lactase non-persistence was well in agreement in this study with published figures for the prevalences of adult-type hypolactasia in Africans and Whites. The C/C(-13910) genotype was associated with very low lactase activity (<10 U/g protein) in the majority of children tested at 8 years of age and in every child older than 12 years of age giving a specificity of 100% and sensitivity of 93% for the genetic test. The decline of lactase activity was somewhat earlier in African compared with Finnish children with C/C(-13910) genotype (p<0.03). CONCLUSIONS Genetic test of C/T(-13910) polymorphism can be used as a first stage screening test for adult-type hypolactasia.

Abstract
An ideal operation for necrotising enterocolitis (NEC) would be quick and reliable, remove all nonviable bowel, minimise the loss of intestinal length, permit early restoration of intestinal continuity, and minimise the need for secondary operations. No operation currently meets all these needs. In this study we review our experience with the Santulli enterostomy in NEC. From 1992 to 1998, 19 patients (16 males, three females) underwent a Santulli enterostomy for Bell grade III NEC. The median gestational age at birth (GA) was 26 weeks (range 23-30), and the median birth weight 755 g (range 600-1095). The median patient age at operation was 10 days (range 3-59), and the median operative time was 55 min (range 25-90). Sixteen (84%) patients survived. Complications included leakage of the Santulli anastomosis in four cases, stomal necrosis in two cases, additional intestinal necrosis in two cases, leakage of a concurrent intra-abdominal anastomosis in two cases, and intestinal obstruction in four cases. Twelve patients underwent relaparotomy. Enteral feeding was started at a median of 5 days postoperatively (range 2-9), with full oral feeding possible at a median of 21 days (range 10-128). The median time until closure of the enterostomy was 48 days and the median hospital stay 87 days (range 19-197). After stomal closure, obstructive symptoms necessitated a new Santulli enterostomy in two patients and a revision of the anastomosis in one patient. Santulli enterostomy can be used to treat NEC even in very small premature babies. It enables rapid recovery of intestinal continuity and early stomal closure. However, the operation is technically demanding and carries significant morbidity.

Abstract
Gastroesophageal reflux (GER) is common after repair of esophageal atresia with a distal tracheoesophageal fistula (EATOF). In a retrospective study we assessed whether early 18-h pH monitoring can predict the development of EATOF-associated gastroesophageal reflux. During 1980-1997, 90 consecutive patients had primary repair for EATOF. Development of GER was classified as favorable if the patient developed no esophagitis or mild esophagitis and needed no antireflux medication, and as unfavorable if the patient developed moderate or secondary esophagitis or required an antireflux procedure. Patients who developed unfavorable GER outcome before pH monitoring or needed secondary reconstruction or those whose endoscopic follow-up data were insufficient were excluded. Eighteen-hour pH monitoring was considered pathologic if esophageal pH was <4 more than 10% of the recorded time or 5% of the recorded time minus 2 h after each meal, or if there were more than three preprandial reflux periods lasting longer than 5 min. A total of fifty patients were included into the study. pH monitoring was performed at the median age of 9.2 (range 2.5-95.0) months and classified as pathologic in 10 and normal in 40 patients. After a median follow-up of 59 (0.3-217.6) months, nine of 10 (90%) patients with pathologic pH monitoring and five of 40 (12.5%) patients with normal pH monitoring developed unfavorable outcomes ( p<.05). We conclude that early pH monitoring predicts the development of significant GER, but because 12.5% of patients with normal early pH monitoring also developed significant GER, early pH monitoring alone does not rule out the development of significant GER.

Abstract
Intestinal immunopathology was studied after allogeneic stem cell transplantation (SCT) in a common clinical setup in 20 children with malignant (n=17) or nonmalignant diseases (n=3) receiving grafts from siblings (7) and unrelated donors (13). In all, 19 had total body irradiation. Duodenal biopsies at 6 and 12 weeks post transplant were evaluated by histology, immunohistochemistry, and ISEL for the detection of T-lymphocytes, inflammatory cytokines, proliferation, and apoptosis. The controls were 12 healthy children and three patients with proven intestinal graft-versus-host disease. An increased rate of apoptosis and proliferation with upregulated expression of HLA-DR antigen was detected up to 3 months post transplant in the SCT patients, even in those with a histologically normal small intestine. A low level of IFNgamma and TNFalpha was observed in the lamina propria. The initial low density of gammadelta-positive T cells had recovered to normal by the time of the second endoscopy at 12 weeks post transplant. We conclude that inflammatory activity and T cell infiltration detected by immunohistochemistry may not belong to the 'normal' recovery of the small intestine after SCT. Increased cell turnover in the intestinal crypts continues until 3 months after SCT, suggesting either an unexpectedly long-lasting effect of transplant-related toxicity or, preferably, an ongoing subclinical alloreactive process, also present in the patients without intestinal symptoms.

Abstract
PURPOSE The aim of this study was to find out how long it is necessary to follow-up esophageal atresia patients endoscopically to prevent irreversible mucosal changes. METHODS Seventy-four of 79 long-term survivors with esophageal atresia and primary anastomosis underwent a total of 322 esophagogastroduodenoscopies during a follow-up period of 0.5 to 19 years (mean, 10.3) after the primary operation. For analysis, the biopsy findings were divided into 2 groups: good, histologically normal or only mildly inflamed mucosa; unfavorable, moderate or severe esophagitis or gastric metaplasia. Fundoplication irrespective of indications was considered unfavorable. The results were analyzed using actuarial survival analysis; the changing point was when a "good" turned into "unfavorable." RESULTS Forty-five patients (61%) remained in the "good" group throughout the study period; 15 of those (20%) had completely normal findings. Nine patients (12%) had moderate, one (1%) had severe esophagitis, and 13 patients (18%) had gastric metaplasia. Fundoplication was performed on 21 patients (28%). CONCLUSIONS About 40% of esophageal atresia patients eventually have significant esophageal mucosal pathology or need to have a fundoplication. The majority of these changes appear before the age of 3 years. Routine endoscopic follow-up of esophageal atresia patients is recommended at least to the age of 3 years.

Abstract
Data on the use of Helicobacter pylori serology in children are limited. We studied the serum antibodies of 105 H. pylori-infected children (median age 9.1 y, range 1.5-17.5 y) using an in-house enzyme immunoassay. At diagnosis of the biopsy-verified infection, IgG antibodies to H. pylori were elevated in 98/105 children (93%) but were at a normal level in 7 children, 5 of whom were < 5 y of age. Serum IgA antibodies to H. pylori were elevated in 40/105 children (38%). The levels of IgG and IgA antibody titers to H. pylori correlated with age (p < 0.001 and p < 0.02, respectively). IgG titers were reduced by > or = 50% in 85% (83/98; median follow-up 0.6 y) of children after therapy. In 56 such children eradication was verified by negative histology or urea breath test but I such child showed Helicobacters on histologic examination. Of the 15 children whose IgG titers dropped by < 50%, 7 were considered positive and 4 negative on the basis of histology or urea breath test. In 3 children, IgG titers returned to pretreatment levels 1 y after a 50% drop was seen. Serology is 1 alternative for monitoring H. pylori infection in children, although its sensitivity is lower in very young children. The length of follow-up needed after eradication, however, is unclear.

Abstract
An intraluminal casein model (ICM) of necrotizing enterocolitis (NEC) is able to produce small-bowel changes reminiscent of human NEC in neonatal animals. We studied bacterial translocation (BT) in NEC induced by using the ICM in neonatal piglets. We also studied whether allopurinol (AL) and N-acetylcysteine (NAC) have an effect on BT and mucosal changes in the ICM of NEC. Twenty-eight neonatal piglets were randomized into four groups. NEC was induced in 21 by injecting casein-d-gluconate into a loop of terminal ileum: group Cas (n = 7) had no premedication, in group Cas/AL (n = 7) intravenous (i.v.) Al (100 mg/kg), and in group Cas/NAC (n = 7) i.v. NAC (200 mg/kg) was given. Group Sham (n = 7) had the ileum injected with 0.9% saline with no premedication. Immediately after the injection a mesenteric lymph node (MLN) adjacent to the loop was harvested for quantitative aerobic bacterial culture; 4 h after the injection another MLN and samples of spleen, liver, kidney, and lung were harvested and cultured. Comparison of the incidence of samples with positive bacterial cultures and the number of colony-forming units (CFU) in samples was made between groups. The severity of NEC in the ileum was graded from 0 to 3 according to macroscopic and histologic findings. NEC changes in the bowel were most severe in Cas piglets, less severe in Cas/NAC piglets ( P < 0.5), and sham piglets had the least severe changes ( P < 0.05). piglets with NEC changes in the ileum had a higher incidence of BT into the MLN than piglets without NEC changes ( P < 0.05), but the difference in CFU was not significant ( P > 0.05). In Cas and Cas/NAC piglets a high incidence of BT into the MLN was noted as early at -5 min after casein injection. The incidence of BT into the MLN was significantly higher in Cas and Cas/NAC piglets than in Sham piglets ( P < 0.05), the difference in CFU being not significant ( P > 0.05). BT in Cas/Al piglets was not significantly different from that of Cas piglets ( P > 0.05), but less than in Cas/NAC piglets ( P < 0.05). Four hours after casein injection into the ileum there was significant BT into the MLN. Premedication with NAC was associated with less severe NEC changes, but neither NAC nor AL significantly affected BT.

Abstract
BACKGROUND In children with congenital abdominal wall defects (CAWD), surgical treatment of the abdominal defect and the associated anomalies cause considerable morbidity in the first years of life. Afterward, most of the CAWD patients with correctable anomalies develop as other children. The morbidity and quality of life (QoL) of CAWD patients who have reached their adulthood is less well known and the subject of this study. METHODS A 3-part questionnaire was sent to 75 former patients with CAWD, aged 17 years or more. The first part included questions about health, symptoms, and education; the second part consisted of 3 tests of psychosocial functioning; and the third part was a SF-36 questionnaire measuring the QoL. RESULTS Of the 75 patients, 57 (76%) answered: (25 males, 32 females); omphalocele (n = 16) gastroschisis (n = 11); median age, 27 (range, 17 to 48) years. With the exception of rheumatoid arthritis (in 7% of patients), the prevalence of acquired diseases in CAWD patients was comparable with that of the general population; 50 of 57 (88%) considered their health good. The most frequent causes of morbidity were disorders in the abdominal scar in 21 (37%) patients, and functional gastrointestinal disorders in 29 (51%) of patients. Low self-esteem was found in 12% of patients, but the QoL and educational level of CAWD patients were not different from that of the general population. CONCLUSIONS In CAWD patients the morbidity from acquired disorders is similar to morbidity in the general population. Disorders with the abdominal scar and various functional gastrointestinal disorders are common, but they rarely cause serious problems. The majority of CAWD patients have a quality of life not different from the general population.

Abstract
Childhood factors such as low socioeconomic status are risk factors for Helicobacter pylori infection and Streptococcus mutans-related dental caries. We examined whether H. pylori infection and dental caries are present today in the same group of children examined previously. We reviewed the public dental health service files of 21 H. pylori-positive children (upper gastrointestinal endoscopy at a median age of 13.5 y) and 27 H. pylori-negative children (endoscopy at a median age of 12.5 y) examined during 1995-98 at the Helsinki University Central Hospital, Finland. All H. pylori-positive children had experienced dental caries in their primary or permanent teeth or in both whereas among H. pylori-negative children the respective proportion was 70% (p < 0.01). At the age of 7 y, 18% (3/17) of the H. pylori-positive children had experienced caries in permanent teeth as compared to 0% among H. pylori-negative children (0/24; p < 0.05). At the age of 12 y, H. pylori-positive children had more decayed, missing or filled permanent teeth than H. pylori-negative children (80% vs. 38%; p < 0.05). Although a causal relationship between H. pylori and dental caries is unlikely, it is possible that H. pylori-infected children have an increased risk of other health problems, such as dental caries, for which proper treatment is needed.

Abstract
BACKGROUND Liver transplantation (Tx) has become an alternative treatment of malignant childhood liver tumors, and the importance of careful pretransplantation evaluation has been emphasized. Anti-alpha-fetoprotein (AFP) imaging has been suggested for evaluation of adult patients with AFP-positive tumors. METHODS Antibody imaging utilizing Tc-99 m-labeled monoclonal anti-AFP Fab' fragments was used to demonstrate pathologic uptake in hepatoblastoma (HB). RESULTS Radical operation or liver Tx was not possible after four cycles of chemotherapy in a child with HB because of a single extrahepatic metastasis. Chemotherapy was continued, and reevaluation with anti-AFP imaging demonstrated a pathologic uptake only in the liver. Subsequently, a right liver lobe resection was performed. Along with a new rise in serum AFP, repeated anti-AFP imaging revealed active liver tumor but no metastases. A liver Tx was performed, and the child is well with a normal serum AFP level 18 months after the operation. CONCLUSION This is the first case of pediatric HB in which anti-AFP imaging has been successfully used for patient management.

Abstract
BACKGROUND/PURPOSE Chronic or recurring enterocolitis is a rare but perplexing complication of Hirschsprung's disease affecting especially patients with altered immune defense such as those with Down's syndrome. Sodium cromoglycate (SCG) is a nonabsorbable mast cell stabilizing agent that has been documented to be effective in the treatment of inflammatory bowel disease. The authors studied the effect of SCG in Hirschsprung patients with refractory chronic or recurrent enterocolitis. METHODS Eight patients (4 with Down's syndrome, 2 with other chromosomal aberrations, 2 otherwise healthy; age range from 4 to 22 years) with chronic (5 patients) or recurrent (>6 episodes/year, 3 patients) enterocolitis received 100 to 200 mg of SCG 4 times a day depending on the age of the patient. The chronic diarrhea or recurrent bouts of enterocolitis in the patients were refractory to dietary management and enteral antibiotics. Before the treatment all patients had ileocolonoscopy, the results of which showed macroscopic and histological chronic inflammation in all cases. No neuronal abnormalities were detected in biopsy results. None of the patients had colonic dilatation or increased anorectal resting pressures suggesting outlet obstruction. RESULTS The follow-up of the patients ranges from 8 months to 26 months. Three of the 5 patients with chronic enterocolitis responded favorably. In these 3 patients the median number of daily bowel movements decreased from 6 to 3, and none experienced bouts of abdominal distension. Diarrhea-related soiling decreased also significantly. Two of the 3 patients with recurrent enterocolitis have remained asymptomatic, and none has required antibiotics after the onset of SCG treatment; one patient had an episode of enterocolitis after 12 months treatment. Two patients with chronic enterocolitis did not respond to SCG. No side effects of SCG were encountered. CONCLUSIONS This preliminary and nonrandomized study suggests that SCG is an effective treatment modality for chronic or recurrent enterocolitis in patients with Hirschsprung's disease. Because SCG is not absorbed From the intestinal tract there are no systemic side effects.

Abstract
BACKGROUND/PURPOSE Gastric or rectosigmoid intramural pH (pHi) is considered a reliable indicator of splanchnic perfusion. The aim of this study was to evaluate whether rectosigmoid pHi reflects the severity of bowel damage in experimental necrotizing enterocolitis (NEC). METHODS A total of 36 neonatal piglets, (median age, 3; range, 1 to 11 days; median weight, 2.5; range, 1.2 to 3.8 kg), were anesthetized, ventilated mechanically, and had invasive monitoring of hemodynamics. A sigmoid tonometer was inserted into the rectosigmoid colon. Enterocolitis was induced in 27 piglets by intraluminal injection of casein-d-gluconate (16.0 mL/kg) into terminal 100 cm of the ileum. Nine control piglets received an equal amount of intraluminal saline. NEC was graded macroscopically as follows: 0, no changes; 1, mild; 2, moderate; and 3, severe. Histology was evaluated according to Chiu scale from 0 to 5. RESULTS The macroscopical bowel injury in caseine-injected piglets was as follows: grade 3 (n = 6), grade 2 (n = 9), grade 1 (n = 12). All control piglets showed macroscopically normal bowel (grade 0). All affected bowels showed histologic changes (Chiu's scale 2 to 4). All study animals had an initial drop of pHi after injection of casein or saline. In control piglets and those with mild NEC (grade 1) pHi tended to return to preinjection level. In animals with moderate or severe NEC (grade 2 to 3) the initial drop was deeper and the pHi continued to decrease significantly throughout the experiment (P < .05). In the arterial pH and mean blood pressure there were no statistically significant differences between piglets with no NEC and mild NEC, and these with moderate or severe NEC. CONCLUSION Drop in rectosigmoid pHi was the most sensitive and earliest sign of severe mucosal necrosis of ileum in this experimental NEC model.

Abstract
cagA, vacA s and m genotypes and iceA alleles were analyzed from Helicobacter pylori strains isolated from 17 Finnish children and 32 children of non-Finnish origin living in Finland. Twelve children in the latter group were eastern European and 15 were of African origin. Only three children of non-Finnish origin were born in Finland. The vacA sla subtype was more prevalent in the isolates from Finnish children than African children (76% vs. 7%, P<0.001); vacA s1b frequencies were 5% and 67%, respectively (P<0.001). The iceA1 allele was significantly more prevalent in African than Finnish isolates (93% vs. 35%, P< 0.01). Considerable variation was noted in the frequency of vacA s1 subtypes and iceA alleles in children originating from different geographic regions, but the geographic variation of s1 subtypes resembled that described in other reports.

Abstract
BACKGROUND/PURPOSE Transanal mucosal proctectomy with low coloanal anastomosis has been used widely in the treatment of rectal malignancies, ulcerative colitis, and familial polyposis. The use of this technique for Hirschsprung's disease is a relatively new concept. The aim of this study was to evaluate and compare the results of transanal endorectal coloanal anastomosis (TECA) for Hirschsprung's disease from 2 centers. METHODS All children who underwent TECA for Hirschsprung's disease at Alder Hey Children's Hospital, Liverpool, England from January 1995 to December 1998 (n = 41) and the Children's Hospital, Helsinki, Finland from June 1988 to December 1998 (n = 95) were evaluated. Patient demographics, age at diagnosis, initial management, length of aganglionic segment, and age at operation were documented. Postoperative complications and functional outcome were analyzed. RESULTS Patient demographics were similar in the 2 centers. Age at diagnosis was less than 1 month in 71% of children at Liverpool, compared with 53% at Helsinki. Sixteen (39%) patients in Liverpool and 75 (79%) patients in Helsinki underwent primary TECA without colostomy. Postoperative enterocolitis occurred in 14 of 136 patients (10%). An ischemic stricture of the colon was documented in 4 children in the Liverpool series, 2 of whom had TECA as a salvage procedure after a previously failed Duhamel pull-through operation. Frequency of bowel movements, seen in the immediate postoperative period in most patients gradually improved with time from a median of 5 (range, 2 to 12) bowel movements a day at 3 months after TECA to 2 (range, 1 to 6) bowel movements a day at 2 years' follow-up. Assessment of continence was possible in 51 of 136 patients (37%) over the age of 4 years. Thirty-nine children had normal bowel function giving an overall success rate of 76%. CONCLUSIONS Transanal endorectal coloanal anastomosis is a good technique for treatment of Hirschsprung's disease with few operation-related complications. Based on the data emerging from these 2 centers the functional outcome is highly satisfactory and comparable with other established procedures.

Abstract
BACKGROUND/PURPOSE Gastroesophageal reflux (GER) is considered common in patients with congenital abdominal wall defects (CAWD). The aim of this study was to find out the frequency of GER in children with CAWD and, in particular, whether there is difference between patients with omphalocele and gastroschisis. METHODS Forty-two children, 19 with gastroschisis and 23 with omphalocele were examined for GER at the median age of 12.0 months (range, 1 to 132). Esophagoduodenoscopy with biopsies was performed on all patients. Eighteen patients underwent 18-hour esophageal pH-monitoring. RESULTS GER was detected in 13 patients. All but one patient of the 13 had either macroscopic or microscopic esophagitis. One patient had pathological pH monitoring only. In children with omphalocele, the incidence of GER was 43% (10 of 23), whereas in gastroschisis patients the incidence was 16% (3 of 19), (P value, not significant). The median age of omphalocele patients with GER was significantly lower (7 months) than the median age of those without GER (72 months; P = .01). In patients with gastroschisis age made no difference. Six of 32 patients (19%) with primary fascial closure (small defects) had GER, whereas 7 of 10 patients (70%) in which primary fascial closure was impossible (large defects) had GER (P < .01). CONCLUSION CAWD patients, especially those with omphalocele and a large defect have a high incidence of GER complicated by esophagitis during the first few years of life.

Abstract
BACKGROUND Helicobacter pylori infection is likely to be acquired at an early age. The factors leading to active inflammation in childhood, however, are largely unknown. SUBJECTS AND METHODS We determined the CagA status, the best characterized virulence factor of H. pylori, and serum antibodies of IgG and IgA classes to H. pylori in 39 infected children. RESULTS Mononuclear cell infiltration in the antrum but not in the gastric body was more intense in CagA-positive children than in CagA-negative children. The degree of polymorphonuclear cell infiltration on the other hand was independent of the CagA status. The antibody titers of IgG and IgA classes to H. pylori were higher in CagA-positive than in CagA-negative infections (P<0.001 and P<0.01, respectively). IgG antibody titers to H. pylori correlated directly with the density of mononuclear and polymorphonuclear cell infiltration in the gastric antrum but not in the gastric body. CONCLUSION H. pylori-infected children with CagA antibodies seem to have a more severe inflammation in the gastric antrum than CagA-negative children as shown by an increase in the density of antral mononuclear cells. A finding of higher serum antibody titers to H. pylori in CagA-positive children may be related to this enhancement of inflammation.

Abstract
BACKGROUND Gastritis is a common finding in patients with inflammatory bowel disease. However, the association of gastritis with Helicobacter pylori is unclear in these patients. METHODS The prevalence of antibodies for H. pylori in serum was determined in 47 pediatric patients with inflammatory bowel disease (19 with Crohn's disease, 21 with ulcerative colitis, and 7 with unclassified disease). H. pylori antibodies of the IgG and IgA classes were measured by enzyme immunoassay in 24 patients at the time of diagnosis of inflammatory bowel disease and in 23 more patients during the follow-up of inflammatory bowel disease (mean follow-up, 3.5 years; range 1-10 years). Esophagogastroduodenoscopy was performed on 40 patients during the examination for inflammatory bowel disease. RESULTS In contrast to earlier findings, no patient was determined to be positive for H. pylori, either in serologic or histologic examination. This negative finding was unexpected, because it is known that approximately 10% of asymptomatic Finnish children have antibodies for H. pylori in serum and approximately 10% of analyses of specimens obtained in gastric antral biopsies obtained at the Hospital for Children and Adolescents, Helsinki, Finland, are positive for H. pylori. CONCLUSIONS Permanent colonization of the stomach with H. pylori is unusual in children with inflammatory bowel disease.

Abstract
BACKGROUND Constipation is one of the most important functional sequelae in patients with anorectal malformations. The cause of this motility disorder is unknown. AIM The purpose of this study was to assess total colonic transit time (TCT) and segmental colonic transit time (SCT) in patients with anorectal malformations. METHOD Ninety patients with anorectal malformations (40 low and 50 high; median age, 7 years; range, 3 to 13) and twenty-five healthy children (median age, 8 years; range, 3 to 14 years) underwent measurement of TCT and SCT by the saturation technique. Ten radiopaque markers were ingested daily for 6 days followed by administration of a single abdominal x-ray on day 7. TCT in days was calculated by dividing the number of retained markers in the whole colon by the daily intake. SCT in four colonic segments (right, transverse, left, rectosigmoid) was described as a percentage of TCT (markers in one segment versus total number of retained markers). In high anomalies the degree of rectosigmoid dilatation was assessed by contrast enemas taken before closure of the stoma and later during follow-up. RESULTS TCT was significantly (P < .03) prolonged in patients with anorectal anomalies (median high, 2.1 days; low, 1.9 days versus 1.3 in healthy subjects). In patients with high anomalies right SCT was prolonged when compared with low anomalies and healthy subjects (median high, 24% versus low, 10% and normal subjects, 10%; P < .01). The impairment was more severe in patients with very high anomalies (P < .005). Patients with a low anomaly had prolonged rectosigmoid SCT (median low, 65% versus high, 43% and normal subjects, 49%; P < .05). Prolonged right colonic SCT and TCT correlated with symptomatic constipation in patients with high anomalies (P < .05) but not with those who had low anomalies. Impaired overall functional outcome correlated with prolonged right colonic SCT in patients with high anomalies and with prolonged rectosigmoid SCT in patients with low anomalies. There was no correlation between the degree of rectosigmoid dilatation and SCT or TCT. CONCLUSION Patients with anorectal malformations have abnormal colonic motility. The type of motility disorder in low anomalies is rectosigmoid hypomotility. In patients with high anomalies the motility disturbance is more generalized. The overall functional outcome was strongly related to the degree of these motility disorders.

Abstract
Between 1948 and 1980, 107 of 164 patients survived after repair of a congenital diaphragmatic defect. Sixty of the survivors (mean age, 29.6 years; SD, 9.0 years) underwent clinical examination, chest radiography, spirometry, and diffusing capacity measurement 11 to 41 years after the diaphragmatic repair. Twenty-seven of the 60 had body plethysmography, xenon 133 radiospirometry, and a test of bronchial hyperreactivity. Subjective physical performance was below average for eight patients (13%), seven patients (12%) had asthma, and four patients (7%) reported increased susceptibility to respiratory infections. Thirty-one patients (52%) had ventilatory impairment, which was obstructive in nine (15%), restrictive in seven (12%), and obstructive and restrictive in 15 patients (25%). Nine (35%) of the 26 patients tested had bronchial hyperreactivity. The presence of ventilatory impairment and bronchial hyperreactivity correlated with the initial clinical severity of the affliction. Chest asymmetry (29 patients; 48%) and scoliosis (16 patients; 27%) were more common among patients with ventilatory impairment than among those with normal spirometric findings. Ventilatory impairment and thoracic deformities are common in adults with repaired diaphragmatic defects. Surveillance should begin in infancy and continue into adulthood.

Abstract
Between 1948 and 1980, 107 of 164 patients survived after repair of congenital diaphragmatic defects. To study chest wall and spinal deformities among these patients, 60 survivors (mean age, 29.6 +/- 9.0 years) underwent clinical examination, chest and spinal radiography, spirometry, and diffusing capacity measurements. Twenty-seven of these patients also had body pletysmography, xenon 133 radiospirometry, and a test for bronchial hyperreactivity. Chest asymmetry was present in 29 patients (48%). Eleven patients (18%) had pectus excavatum, and one had a pectus carinatum deformity. Anterior asymmetry, pectus deformities, and a flat chest were more common among the patients who initially had a large diaphragmatic defect. Two patients underwent anterior thoracoplasty because of their deformities. Sixteen patients (27%) had significant scoliosis (Cobb angle > or = 10 degrees). Scoliosis was more common in patients with ventilatory impairment than in those with normal lung function. One patient required spinal stabilization, one with severe kyphoscoliosis remains under observation, and a patient with moderate scoliosis was treated with a spinal brace. The results of this study indicate that chest wall deformities and scoliosis are common among adults with repaired congenital diaphragmatic defects. In most patients the deformity is mild, but some will require surgery. Surveillance until adulthood is appropriate.

Abstract
Recent reports indicate a significant incidence of gastroesophageal reflux (GER) and other nonpulmonary problems after the repair of congenital diaphragmatic defects. Reports of follow-up through adulthood are few and based on a small number of patients. From 1948 to 1982, 107 of 164 patients (65%) treated at the authors' institution survived after repair of congenital diaphragmatic hernia or eventration. Sixty of the 107 survivors (56%) (mean age, 29.6 years; SD, 9.0 years) were interviewed and examined clinically. Forty-one of the sixty (68%) underwent upper gastrointestinal endoscopy. Early postoperative GER was recorded for 11 of the 60 patients (18%). Two of them underwent fundoplication because of an esophageal stricture. At the time of the follow-up study, 38 of the 60 (63%) reported symptoms suggestive of GER. Endoscopic or histological GER (esophagitis, Barrett's esophagus) was present in 22 of 41 patients (54%). No significant correlation between the initial severity of the diaphragmatic defect or neonatal postoperative problems and the late GER could be verified. Intestinal obstruction requiring hospital admission occurred in 12 of the 60 patients (20%), eight of whom had surgical treatment between 1 month and 20 years after repair of the diaphragmatic defect. GER and intestinal obstruction are common among patients who have undergone repair of a congenital diaphragmatic defect. Investigations for GER should be performed routinely during the follow-up of these patients.
