Abstract
Gonorrhoea cases increased steeply in women aged 20 to 24 years across 15 EU/EEA countries in July to December 2022 and January to June 2023 with, respectively, 73% and 89% more cases reported than expected, based on historical data from 2015 to 2019. Smaller increases among men due to heterosexual transmission were observed in nine EU/EEA countries. Interventions to raise awareness among young people about sexually transmitted infection risks are needed, emphasising the benefit of safe sexual practices and testing.

Abstract
BACKGROUND Congenital diaphragmatic hernia (CDH) accounts for 8% of all major congenital anomalies. Neonates who are small for gestational age (SGA) generally have a poorer prognosis. We sought to identify risk factors and variables associated with outcomes in neonates with CDH who are SGA in comparison to neonates who are appropriate for gestational age (AGA). METHODS We used the multicenter Diaphragmatic Hernia Research & Exploration Advancing Molecular Science (DHREAMS) study to include neonates enrolled from 2005 to 2019. Chi-squared or Fisher's exact tests were used to compare categorical variables and t tests or Wilcoxon rank sum for continuous variables. Cox model analyzed time to event outcomes and logistic regression analyzed binary outcomes. RESULTS 589 neonates were examined. Ninety were SGA (15.3%). SGA patients were more likely to be female (p = 0.003), have a left sided CDH (p = 0.05), have additional congenital anomalies and be diagnosed with a genetic syndrome (p < 0.001). On initial single-variable analysis, SGA correlated with higher frequency of death prior to discharge (p < 0.001) and supplemental oxygen requirement at 28 days (p = 0.005). Twice as many SGA patients died before repair (12.2% vs 6.4%, p = 0.04). Using unadjusted Cox model, the risk of death prior to discharge among SGA patients was 1.57 times the risk for AGA patients (p = 0.029). There was no correlation between SGA and need for ECMO, pulmonary hypertensive medication at discharge or oxygen at discharge. After adjusting for confounding variables, SGA no longer correlated with mortality prior to discharge or incidence of unrepaired defects but remained significant for oxygen requirement at 28 days (p = 0.03). CONCLUSION Infants with CDH who are SGA have worse survival and poorer lung function than AGA infants. However, the outcome of SGA neonates is impacted by other factors including gestational age, genetic syndromes, and particularly congenital anomalies that contribute heavily to their poorer prognosis.

Abstract
Following the report of a non-travel-associated cluster of monkeypox cases by the United Kingdom in May 2022, 41 countries across the WHO European Region have reported 21,098 cases and two deaths by 23 August 2022. Nowcasting suggests a plateauing in case notifications. Most cases (97%) are MSM, with atypical rash-illness presentation. Spread is mainly through close contact during sexual activities. Few cases are reported among women and children. Targeted interventions of at-risk groups are needed to stop further transmission.

Abstract
BACKGROUND/PURPOSE As survival rates for patients with congenital diaphragmatic hernia (CDH) increase, long-term sequelae become increasingly prevalent. We present the outcomes of patients who underwent CDH repair at our institution and discuss standardization of follow-up care in our long-term multidisciplinary follow-up clinic. METHODS A retrospective review of patients followed in multidisciplinary clinic after CDH repair at our institution from January 1, 2005 to December 1, 2020. RESULTS A total of 193 patients met inclusion criteria, 73 females (37.8%) and 120 males (62.2%). Left-sided defects were most common (75.7%), followed by right-sided defects (20.7%). Median age at repair was 4 days (IQR 3-6) and 59.6% of all defects required patch repair. Median length of stay was 29 days (IQR 16.8-50.0). Median length of follow up was 49 months (IQR 17.8-95.3) with 25 patients followed for more than 12 years. Long-term outcomes included gastroesophageal reflux disease (42.0%), diaphragmatic hernia recurrence (10.9%), asthma (23.6%), neurodevelopmental delay (28.6%), attention deficit hyperactivity disorder (7.3%), autism (1.6%), chest wall deformity (15.5%), scoliosis (11.4%), and inguinal hernia (6.7%). CONCLUSION As survival of patients with CDH improves, long-term care must be continuously studied and fine-tuned to ensure appropriate surveillance and optimization of long-term outcomes.

Abstract
Congenital diaphragmatic hernia (CDH) is a severe congenital anomaly that is often accompanied by other anomalies. Although the role of genetics in the pathogenesis of CDH has been established, only a small number of disease-associated genes have been identified. To further investigate the genetics of CDH, we analyzed de novo coding variants in 827 proband-parent trios and confirmed an overall significant enrichment of damaging de novo variants, especially in constrained genes. We identified LONP1 (lon peptidase 1, mitochondrial) and ALYREF (Aly/REF export factor) as candidate CDH-associated genes on the basis of de novo variants at a false discovery rate below 0.05. We also performed ultra-rare variant association analyses in 748 affected individuals and 11,220 ancestry-matched population control individuals and identified LONP1 as a risk gene contributing to CDH through both de novo and ultra-rare inherited largely heterozygous variants clustered in the core of the domains and segregating with CDH in affected familial individuals. Approximately 3% of our CDH cohort who are heterozygous with ultra-rare predicted damaging variants in LONP1 have a range of clinical phenotypes, including other anomalies in some individuals and higher mortality and requirement for extracorporeal membrane oxygenation. Mice with lung epithelium-specific deletion of Lonp1 die immediately after birth, most likely because of the observed severe reduction of lung growth, a known contributor to the high mortality in humans. Our findings of both de novo and inherited rare variants in the same gene may have implications in the design and analysis for other genetic studies of congenital anomalies.

Abstract
The diaphragm is critical for respiration and separation of the thoracic and abdominal cavities, and defects in diaphragm development are the cause of congenital diaphragmatic hernias (CDH), a common and often lethal birth defect. The genetic etiology of CDH is complex. Single-nucleotide variants (SNVs), insertions/deletions (indels), and structural variants (SVs) in more than 150 genes have been associated with CDH, although few genes are recurrently mutated in multiple individuals and mutated genes are incompletely penetrant. This suggests that multiple genetic variants in combination, other not-yet-investigated classes of variants, and/or nongenetic factors contribute to CDH etiology. However, no studies have comprehensively investigated in affected individuals the contribution of all possible classes of variants throughout the genome to CDH etiology. In our study, we used a unique cohort of four individuals with isolated CDH with samples from blood, skin, and diaphragm connective tissue and parental blood and deep whole-genome sequencing to assess germline and somatic de novo and inherited SNVs, indels, and SVs. In each individual we found a different mutational landscape that included germline de novo and inherited SNVs and indels in multiple genes. We also found in two individuals a 343 bp deletion interrupting an annotated enhancer of the CDH-associated gene GATA4, and we hypothesize that this common SV (found in 1%-2% of the population) acts as a sensitizing allele for CDH. Overall, our comprehensive reconstruction of the genetic architecture of four CDH individuals demonstrates that the etiology of CDH is heterogeneous and multifactorial.

Abstract
BACKGROUND Current practice patterns and opinions regarding subspecialization within pediatric surgery are not well known. We aimed to characterize the prevalence of and attitudes surrounding subspecialization within pediatric surgery. METHODS An anonymous survey regarding subspecialization was distributed to all nonresident members of the American Pediatric Surgical Association. RESULTS Of 1118 surveys, we received 458 responses (41%). A majority of respondents labeled themselves 'general pediatric surgeons' (63%), while 34% considered themselves general surgeons with a specific clinical focus, and 3% reported practicing solely within a specific niche. Subspecialists commonly serve as consultants for relevant cases (52%). Common niches included oncology (10%) and anorectal malformations (9%). Subspecialists felt to be necessary included transplant (79%) and fetal (78%) surgeons. Opinions about subspecialization were variable: 41% felt subspecialization improves patient care while 39% believe it is detrimental to surgeon well-roundedness. Only 10% felt subspecialists should practice solely within their subspecialty. Practicing at an academic hospital or fellowship program correlated with subspecialization, while length of time in practice did not. CONCLUSION While pediatric surgeons report that subspecialization may benefit patient care, concerns exist regarding the unfavorable effect it may have on the individual surgeon. A better understanding of how subspecialization affects quality and outcomes would help clarify its utility. TYPE OF STUDY Review article. LEVEL OF EVIDENCE Level V.

Abstract
Purpose Congenital diaphragmatic hernia (CDH) is associated with significant mortality and long-term morbidity in some but not all individuals. We hypothesize monogenic factors that cause CDH are likely to have pleiotropic effects and be associated with worse clinical outcomes. Methods We enrolled and prospectively followed 647 newborns with CDH and performed genomic sequencing on 462 trios to identify de novo variants. We grouped cases into those with and without likely damaging (LD) variants and systematically assessed CDH clinical outcomes between the genetic groups. Results Complex cases with additional congenital anomalies had higher mortality than isolated cases (P=8×10−6). Isolated cases with LD variants had similar mortality to complex cases and much higher mortality than isolated cases without LD (P=3×10−3). The trend was similar with pulmonary hypertension at 1 month. Cases with LD variants had an estimated 12–17 points lower scores on neurodevelopmental assessments at 2 years compared to cases without LD variants, and this difference is similar in isolated and complex cases. Conclusion We found that the LD genetic variants are associated with higher mortality, worse pulmonary hypertension, and worse neurodevelopment outcomes compared to non-LD variants. Our results have important implications for prognosis, potential intervention and long-term follow up for children with CDH.

Abstract
BACKGROUND Congenital diaphragmatic hernia (CDH) occurs in 1 out of 2500-3000 live births. Right-sided CDHs (R-CDHs) comprise 25% of all CDH cases, and data are conflicting on outcomes of these patients. The aim of our study was to compare outcomes in patients with right versus left CDH (L-CDH). METHODS We analyzed a multicenter prospectively enrolled database to compare baseline characteristics and outcomes of neonates enrolled from January 2005 to January 2019 with R-CDH vs. L-CDH. RESULTS A total of 588, 495 L-CDH, and 93 R-CDH patients with CDH were analyzed. L-CDHs were more frequently diagnosed prenatally (p=0.011). Lung-to-head ratio was similar in both cohorts. R-CDHs had a lower frequency of primary repair (p=0.022) and a higher frequency of need for oxygen at discharge (p=0.013). However, in a multivariate analysis, need for oxygen at discharge was no longer significantly different. There were no differences in long-term neurodevelopmental outcomes assessed at two year follow up. There was no difference in mortality, need for ECMO, pulmonary hypertension, or hernia recurrence. CONCLUSION In this large series comparing R to L-CDH patients, we found no significant difference in mortality, use of ECMO, or pulmonary complications. Our study supports prior studies that R-CDHs are relatively larger and more often require a patch or muscle flap for repair. TYPE OF STUDY Prognosis study LEVEL OF EVIDENCE: Level II.

Abstract
Choledochal cysts (CDCs) and biliary atresia (BA) are rare pediatric hepatobiliary anomalies that require surgical intervention due to increased risk of malignancy and liver failure, respectively. The underlying disease and operative procedures place patients at risk for long-term complications, which may continue to affect them into adulthood. Lack of a transitional care model in the health-care system potentiates the challenges they will face following aging out of their pediatric providers' care. We sought to elucidate the long-term complications and challenges patients with CDCs and BA face, review the current literature regarding transitioning care, and propose guidelines aiding adult providers in continued care and surveillance of these patients. A literature review was performed to assess short-term and long-term complications after surgery and the current standards for transitioning care in patients with a history of CDCs and BA. While transitional programs exist for patients with other gastrointestinal diseases, there are few that focus on CDCs or BA. Generally, authors encourage medical record transmission from pediatric to adult providers, ensuring accuracy of information and compliance with treatment plans. Patients with CDCs are at risk for developing biliary malignancies, cholangitis, and anastomotic strictures after resection. Patients with BA develop progressive liver failure, necessitating transplantation. There are no consensus guidelines regarding timing of follow up for these patients. Based on the best available evidence, we propose a schema for long-term surveillance.

Abstract
Congenital diaphragmatic hernia (CDH) is a severe birth defect that is often accompanied by other congenital anomalies. Previous exome sequencing studies for CDH have supported a role of de novo damaging variants but did not identify any recurrently mutated genes. To investigate further the genetics of CDH, we analyzed de novo coding variants in 362 proband-parent trios including 271 new trios reported in this study. We identified four unrelated individuals with damaging de novo variants in MYRF (P = 5.3x10(-8)), including one likely gene-disrupting (LGD) and three deleterious missense (D-mis) variants. Eight additional individuals with de novo LGD or missense variants were identified from our other genetic studies or from the literature. Common phenotypes of MYRF de novo variant carriers include CDH, congenital heart disease and genitourinary abnormalities, suggesting that it represents a novel syndrome. MYRF is a membrane associated transcriptional factor highly expressed in developing diaphragm and is depleted of LGD variants in the general population. All de novo missense variants aggregated in two functional protein domains. Analyzing the transcriptome of patient-derived diaphragm fibroblast cells suggest that disease associated variants abolish the transcription factor activity. Furthermore, we showed that the remaining genes with damaging variants in CDH significantly overlap with genes implicated in other developmental disorders. Gene expression patterns and patient phenotypes support pleiotropic effects of damaging variants in these genes on CDH and other developmental disorders. Finally, functional enrichment analysis implicates the disruption of regulation of gene expression, kinase activities, intra-cellular signaling, and cytoskeleton organization as pathogenic mechanisms in CDH.

Abstract
Ventilation practices have changed significantly since the initial reports in the mid 1980 of successful use of permissive hypercapnia and spontaneous ventilation [often called gentle ventilation (GV)] in infants with congenital diaphragmatic hernia (CDH). However, there has been little standardization of these practices or of the physiologic limits that define GV. We sought to ascertain among Diaphragmatic Hernia Research and Exploration; Advancing Molecular Science (DHREAMS) centers' GV practices in the neonatal management of CDH. Pediatric surgeons and neonatologists from DHREAMS centers completed an online survey on GV practices in infants with CDH. The survey gathered data on how individuals defined GV including ventilator settings, blood gas parameters and other factors of respiratory management. A total of 87 respondents, from 12 DHREAMS centers completed the survey for an individual response rate of 53% and a 92% center response rate. Approximately 99% of the respondents defined GV as accepting higher carbon dioxide (PCO2) and 60% of the respondents also defined GV as accepting a lower pH. There was less consensus about the use of sedation and neuromuscular blocking agents in GV, both within and across the centers. Acceptable pH and PCO2 levels are broader than the goal ranges. Despite a lack of formal standardization, the results suggest that GV practice is consistently defined as the use of permissive hypercapnia with mild respiratory acidosis and less consistently with the use of sedation and neuromuscular blocking agents. GV is the reported practice of surveyed neonatologists and pediatric surgeons in the respiratory management of infants with CDH.

Abstract
BACKGROUND Congenital diaphragmatic hernia (CDH) is a prevalent major congenital anomaly with significant morbidity and mortality. Thirty to 40% mortality in CDH is largely attributed to pulmonary hypoplasia and pulmonary hypertension (PH). We hypothesized that the underlying genetic risk factors for hereditary PH are shared with CDH associated PH. METHODS Participants were recruited as part of the Diaphragmatic Hernia Research & Exploration; Advancing Molecular Science (DHREAMS) study, a prospective cohort of neonates with a diaphragmatic defect enrolled from 2005 to 2012. PH affected patients with available DNA for sequencing had one of the following: moderate or severe PH on echocardiography at 3months of age; moderate of severe PH at 1month of age with death occurring prior to the 3month echocardiogram; or on PH medications at 1month of age. We sequenced the coding regions of the hereditary PH genes bone morphogenetic protein receptor type II (BMPR2), caveolin 1 (CAV1) and potassium channel subfamily K, member 3 (KCNK3) to screen for mutations. RESULTS There were 29 CDH patients with PH including 16 males and 13 females. Sequencing of BMPR2, CAV1, and KCNK3 coding regions did not identify any pathogenic variants in these genes. TYPE OF STUDY Prognosis study LEVEL OF EVIDENCE: Level IV.

Abstract
Lower-extremity ischemia is a significant complication in children on femoral venoarterial extracorporeal membrane oxygenation (VA ECMO). Our institution currently routinely uses distal perfusion catheters (DPCs) in all femoral arterial cannulations in attempts to reduce ischemia. We performed a single-center, retrospective review of pediatric patients supported with femoral VA ECMO from January 2005 to November 2015. The outcomes of patients with prophylactic DPC placement at cannulation (prophylactic DPC) were compared to a historical group with DPCs placed in response only to clinically evident ischemic changes (reactive DPC). Ischemic complication requiring invasive intervention (fasciotomy or amputation) was the primary outcome. Twenty-nine patients underwent a total of 31 femoral arterial cannulations, 17 with prophylactic DPC and 14 with reactive DPC. Ischemic complications requiring invasive intervention developed in 2 of 17 (12%) prophylactic DPC patients versus 4 of 14 (29%) reactive DPC. In the reactive DPC group, 7 of 14 (50%) had ischemic changes postcannulation, six underwent DPC placement, and three out of six of these patients still required invasive intervention. One of the seven patients had ischemic changes, did not undergo DPC, and required amputation. While a greater percentage of patients in the prophylactic group was cannulated during extracorporeal cardiopulmonary resuscitation (ECPR), statistical significance was not otherwise demonstrated. We demonstrate feasibility of superficial femoral artery (SFA) access in pediatric patients. We note fewer ischemic complications with prophylactic DPC placement, and observe that salvaging a limb with a reactive DPC was only successful 50% of the time. Although there was no statistical difference in the primary outcome between the two groups, limitations and confounding factors include small sample size and a greater percentage of patients in the prophylactic DPC group cannulated with ECPR in progress.

Abstract
Survival is significantly compromised in infants born with congenital diaphragmatic hernia and major cardiac anomalies. Mortality is highest when congenital diaphragmatic hernia occurs in association with d-transposition of the great arteries. We present three infants with congenital diaphragmatic hernia associated with d-transposition of the great arteries from a single institution. All three infants survived to discharge after surgical repair/palliation of both the diaphragmatic hernia and heart defect and are doing well at last follow-up. The clinical course and management of these three patients are described.

Abstract
BACKGROUND Children with heterotaxy syndrome and intestinal rotational anomalies (IRA) are at risk for midgut volvulus and ischemia. Controversy exists regarding risks and benefits of prophylactic Ladd procedures. The purpose of this study is to assess the impact of Ladd procedures on adverse events for children with heterotaxy and IRA. METHODS A retrospective cohort study using the Pediatric Health Information System (PHIS) database was performed. All children with heterotaxy and IRA admitted at age ≤ 30 days and discharged between 1/1/2004 and 1/1/2011 were included with a minimum 2-year follow-up period. The primary outcome was major morbidity, defined as a composite variable for intestinal obstruction/volvulus, ischemia, or resection, or inhospital mortality. Univariable and multivariable analyses were performed. RESULTS There were 325 patients who met the inclusion criteria, including 92 (28%) patients with single ventricles. Mean gestational age was 38.0 ± 2.1 weeks and birth weight was 3.1 ± 0.6 kg. Ladd procedure was performed during initial hospitalization on 188 (58%) children. In multivariable analyses, Ladd procedure on initial hospitalization was associated with a 2.2 times increased odds of adverse events on subsequent admissions (95% CI 1.3-4.0, p = 0.007). CONCLUSIONS Ladd procedure is associated with increased odds of adverse events for children with heterotaxy and IRA.

Abstract
Congenital diaphragmatic hernia (CDH) is a serious birth defect that accounts for 8% of all major birth anomalies. Approximately 40% of cases occur in association with other anomalies. As sporadic complex CDH likely has a significant impact on reproductive fitness, we hypothesized that de novo variants would account for the etiology in a significant fraction of cases. We performed exome sequencing in 39 CDH trios and compared the frequency of de novo variants with 787 unaffected controls from the Simons Simplex Collection. We found no significant difference in overall frequency of de novo variants between cases and controls. However, among genes that are highly expressed during diaphragm development, there was a significant burden of likely gene disrupting (LGD) and predicted deleterious missense variants in cases (fold enrichment = 3.2, P-value = 0.003), and these genes are more likely to be haploinsufficient (P-value = 0.01) than the ones with benign missense or synonymous de novo variants in cases. After accounting for the frequency of de novo variants in the control population, we estimate that 15% of sporadic complex CDH patients are attributable to de novo LGD or deleterious missense variants. We identified several genes with predicted deleterious de novo variants that fall into common categories of genes related to transcription factors and cell migration that we believe are related to the pathogenesis of CDH. These data provide supportive evidence for novel genes in the pathogenesis of CDH associated with other anomalies and suggest that de novo variants play a significant role in complex CDH cases.

Abstract
OBJECTIVES This study evaluates the safety and efficacy of thoracoscopic lobectomy in infants and children. MATERIALS AND METHODS From January 1994 to November 2013, 347 patients underwent video-assisted thoracoscopic lobe resection at two institutions. All procedures were performed by or under the direct guidance of a single surgeon. Patients' ages ranged from 1 day to 18 years, and weights ranged from 2.8 to 78 kg. Preoperative diagnosis included sequestration/congenital pulmonary airway malformation (n=306), severe bronchiectasis (n=24), congenital lobar emphysema (n=13), and malignancy (n=4). RESULTS Of the 347 procedures, 342 were completed thoracoscopically. Operative times ranged from 35 minutes to 240 minutes (average, 115 minutes). Average operative time when a trainee was the primary surgeon was 160 minutes. There were 81 upper, 25 middle, and 241 lower lobe resections. There were four intraoperative complications (1.1%) requiring conversion to an open thoracotomy. The postoperative complication rate was 3.3%, and 3 patients required re-exploration for a prolonged air leak. Hospital length of stay (LOS) ranged from 1 to 16 days (average). In patients <5 kg and <3 months of age, the average operative time was 90 minutes, and the LOS was 2.1 days. CONCLUSIONS Thoracoscopic lung resection is a safe and efficacious technique. With proper mentoring it is an exportable technique, which can be performed by pediatric surgical trainees. The procedures are safe and effective even when performed in the first 3 months of life. Early resection avoids the risk of later infection and malignancy.

Abstract
BACKGROUND Cross-sectional imaging increases accuracy in diagnosing appendicitis. We hypothesized that a radiation-free imaging pathway of ultrasonography selectively followed by MRI would not change clinical end points compared with computed tomography (CT) for diagnosis of acute appendicitis in children. METHODS We retrospectively reviewed children (<18 years old) who had diagnostic imaging for suspected acute appendicitis between November 2008 and October 2012. Before November 2010 CT was used as the primary imaging modality (group A); subsequently, ultrasonography was the primary imaging modality followed by MRI for equivocal findings (group B). Data collected included time from triage to imaging and treatment and results of imaging and pathology. RESULTS Six hundred sixty-two patients had imaging for suspected appendicitis (group A = 265; group B = 397, of which 136 [51%] and 161 [41%], respectively, had positive imaging for appendicitis). Negative appendectomy rate was 2.5% for group A and 1.4% for group B. Perforation rate was similar for both groups. Time from triage to antibiotic administration and operation did not differ between groups A and B. There was higher proportion of positive imaging and appendectomies in group A and thus more negative imaging tests in group B (ultrasonography and MRI), but diagnostic accuracy of the 2 imaging pathways was similar. CONCLUSIONS In children with suspected acute appendicitis, a radiation-free diagnostic imaging of ultrasonography selectively followed by MRI is feasible and comparable to CT, with no difference in time to antibiotic administration, time to appendectomy, negative appendectomy rate, perforation rate, or length of stay.

Abstract
BACKGROUND Congenital diaphragmatic hernia (CDH) is a common birth defect affecting 1 in 3000 births. It is characterised by herniation of abdominal viscera through an incompletely formed diaphragm. Although chromosomal anomalies and mutations in several genes have been implicated, the cause for most patients is unknown. METHODS We used whole exome sequencing in two families with CDH and congenital heart disease, and identified mutations in GATA6 in both. RESULTS In the first family, we identified a de novo missense mutation (c.1366C>T, p.R456C) in a sporadic CDH patient with tetralogy of Fallot. In the second, a nonsense mutation (c.712G>T, p.G238*) was identified in two siblings with CDH and a large ventricular septal defect. The G238* mutation was inherited from their mother, who was clinically affected with congenital absence of the pericardium, patent ductus arteriosus and intestinal malrotation. Deep sequencing of blood and saliva-derived DNA from the mother suggested somatic mosaicism as an explanation for her milder phenotype, with only approximately 15% mutant alleles. To determine the frequency of GATA6 mutations in CDH, we sequenced the gene in 378 patients with CDH. We identified one additional de novo mutation (c.1071delG, p.V358Cfs34*). CONCLUSIONS Mutations in GATA6 have been previously associated with pancreatic agenesis and congenital heart disease. We conclude that, in addition to the heart and the pancreas, GATA6 is involved in development of two additional organs, the diaphragm and the pericardium. In addition, we have shown that de novo mutations can contribute to the development of CDH, a common birth defect.

Abstract
PURPOSE To determine developmental outcomes and associated factors in patients with congenital diaphragmatic hernia (CDH) at 2 years of age. METHODS This is a multicenter prospective study of a CDH birth cohort. Clinical and socioeconomic data were collected. Bayley Scales of Infant Development (BSID-III) and Vineland Adaptive Behavior Scales (VABS-II) were performed at 2 years of age. RESULTS BSID-III and VABS-II assessments were completed on 48 and 49 children, respectively. The BSID-III mean cognitive, language, and motor scores were significantly below the norm mean with average scores of 93 ± 15, 95 ± 16, and 95 ± 11. Ten percent (5/47) scored more than 2 standard deviations below the norm on one or more domains. VABS-II scores were similar to BSID-III scores with mean communication, daily living skills, social, motor, adaptive behavior scores of 97 ± 14, 94 ± 16, 93 ± 13, 97 ± 10, and 94 ± 14. For the BSID-III, supplemental oxygen at 28 days, a prenatal diagnosis, need for extracorporeal membrane oxygenation (ECMO) and exclusive tube feeds at time of discharge were associated with lower scores. At 2 years of age, history of hospital readmission and need for tube feeds were associated with lower scores. Lower socioeconomic status correlated with lower developmental scores when adjusted for significant health factors. CONCLUSION CDH patients on average have lower developmental scores at 2 years of age compared to the norm. A need for ECMO, oxygen at 28 days of life, ongoing health issues and lower socioeconomic status are factors associated with developmental delays.

Abstract
OBJECTIVE To identify clinical factors associated with pulmonary hypertension (PH) and mortality in patients with congenital diaphragmatic hernia (CDH). STUDY DESIGN A prospective cohort of neonates with a diaphragm defect identified at 1 of 7 collaborating medical centers was studied. Echocardiograms were performed at 1 month and 3 months of age and analyzed at a central core by 2 cardiologists independently. Degree of PH and survival were tested for association with clinical variables using Fischer exact test, χ(2), and regression analysis. RESULTS Two hundred twenty patients met inclusion criteria. Worse PH measured at 1 month of life was associated with higher mortality. Other factors associated with mortality were need for extracorporeal membrane oxygenation, patients inborn at the treating center, and patients with a prenatal diagnosis of CDH. Interestingly, patients with right sided CDH did not have worse outcomes. CONCLUSIONS Severity of PH is associated with mortality in CDH. Other factors associated with mortality were birth weight, gestational age at birth, inborn status, and need for extracorporeal membrane oxygenation.

Abstract
BACKGROUND Congenital diaphragmatic hernia (CDH) is a common birth defect with significant morbidity and mortality. Although the aetiology of CDH remains poorly understood, studies from animal models and patients with CDH suggest that genetic factors play an important role in the development of CDH. Chromosomal anomalies have been reported in CDH. METHODS In this study, the authors investigated the frequency of chromosomal anomalies and copy number variants (CNVs) in 256 parent-child trios of CDH using clinical conventional cytogenetic and microarray analysis. The authors also selected a set of CDH related training genes to prioritise the genes in those segmental aneuploidies and identified the genes and gene sets that may contribute to the aetiology of CDH. RESULTS The authors identified chromosomal anomalies in 16 patients (6.3%) of the series including three aneuploidies, two unbalanced translocation, and 11 patients with de novo CNVs ranging in size from 95 kb to 104.6 Mb. The authors prioritised the genes in the CNV segments and identified KCNA2, LMNA, CACNA1S, MYOG, HLX, LBR, AGT, GATA4, SOX7, HYLS1, FOXC1, FOXF2, PDGFA, FGF6, COL4A1, COL4A2, HOMER2, BNC1, BID, and TBX1 as genes that may be involved in diaphragm development. Gene enrichment analysis identified the most relevant gene ontology categories as those involved in tissue development (p=4.4×10(-11)) or regulation of multicellular organismal processes (p=2.8×10(-10)) and 'receptor binding' (p=8.7×10(-14)) and 'DNA binding transcription factor activity' (p=4.4×10(-10)). CONCLUSIONS The present findings support the role of chromosomal anomalies in CDH and provide a set of candidate genes including FOXC1, FOXF2, PDGFA, FGF6, COL4A1, COL4A2, SOX7, BNC1, BID, and TBX1 for further analysis in CDH.

Abstract
PURPOSE Information regarding initial employment of graduating pediatric surgery fellows is limited. More complete data could yield benchmarks of initial career environment. METHODS An anonymous survey was distributed in 2011 to 41 pediatric surgery graduates from all ACGME training programs interrogating details of initial positions and demographics. RESULTS Thirty-seven of 41 (90%) fellows responded. Male to female ratio was equal. Graduates carried a median debt of $220,000 (range: $0-$850,000). The majority of fellows were married with children. 70% were university/hospital employees, and 68% were unaware of a business plan. Median starting compensation was $354,500 (range: $140,000-$506,000). Starting salary was greatest for >90% clinical obligation appointments (median $427,500 vs. $310,000; p=0.002), independent of geographic location. Compensation had no relationship to private practice vs. hospital/university/military position, coastal vs. inland location, and practice sites number. Median clinical time was 75% and research time 10%. 49% identified a formal mentor. Graduates covered 1-5 different offices (median 1) and 1-5 surgery sites (median 2). 60% were satisfied with their compensation. CONCLUSION Recent pediatric surgery graduates are engaged mainly in clinical care. Research is not incentivized. Compensation is driven by clinical obligations. Graduates have limited knowledge of the business plan supporting their compensation, nature of malpractice coverage, and commitments to resources including research. Graduates have important fiscal and parenting obligations.

Abstract
PURPOSE Lung-to-head ratio (LHR) has been used for antenatal evaluation of infants with congenital diaphragmatic hernia (CDH). We hypothesized that LHR was predictive of acute and chronic pulmonary hypertension in infants with CDH. METHODS Echocardiograms on all inborn infants with CDH (December 2001-March 2011) were reviewed. Echocardiograms at 1 and 3 months post-repair and most recent follow-up were assessed for presence of pulmonary hypertension (PAH). LHR, gestational age, birth weight, extracorporeal membrane oxygenation (ECMO), and death rate were obtained. Bivariate and multivariate analyses were performed. RESULTS 106 infants with CDH had LHR obtained at median 28 weeks gestation (median LHR=1.25 [range 0.4-5.3]). Median follow-up was 26.6 months (range 4.6-97.5). The long-term incidence of pulmonary hypertension was 16%. LHR was significantly associated with pulmonary hypertension at one month (p=0.0001) but not at 3 months (p=0.22) or long-term (p=0.54). LHR was predictive of ECMO use (p=0.01) and death (p=0.001). CONCLUSIONS The overall incidence of PAH in infants with CDH decreases over time. Prenatal LHR predicts PAH at one month but not long-term in infants with CDH. The ability for LHR to predict PAH at one month but not long term may suggest remodeling of the pulmonary vasculature over time.

Abstract
Congenital diaphragmatic hernia (CDH) is characterized by incomplete formation of the diaphragm occurring as either an isolated defect or in association with other anomalies. Genetic factors including aneuploidies and copy number variants are important in the pathogenesis of many cases of CDH, but few single genes have been definitively implicated in human CDH. In this study, we used whole exome sequencing (WES) to identify a paternally inherited novel missense GATA4 variant (c.754C>T; p.R252W) in a familial case of CDH with incomplete penetrance. Phenotypic characterization of the family included magnetic resonance imaging of the chest and abdomen demonstrating asymptomatic defects in the diaphragm in the two "unaffected" missense variant carriers. Screening 96 additional CDH patients identified a de novo heterozygous GATA4 variant (c.848G>A; p.R283H) in a non-isolated CDH patient. In summary, GATA4 is implicated in both familial and sporadic CDH, and our data suggests that WES may be a powerful tool to discover rare variants for CDH.

Abstract
OBJECTIVE The optimal treatment of necrotizing enterocolitis (NEC) is a common challenge for pediatric surgeons. Although many studies have evaluated prevention and medical therapy for NEC, few guidelines for surgical care exist. The aim of this systematic review is to review and evaluate the currently available evidence for the surgical care of patients with NEC. METHODS Data were compiled from a search of PubMed, OVID, the Cochrane Library database, and Web of Science from January 1985 until December 2011. Publications were screened, and their references were hand-searched to identify additional studies. Clinicaltrials.gov was also searched to identify ongoing or unpublished trials. The American Pediatric Surgical Association Outcomes and Clinical Trials Committee proposed six questions deemed pertinent to the surgical treatment of NEC. Recent Cochrane Reviews examined three of these topics; a literature review was performed to address the additional three specific questions. RESULTS The Cochrane Reviews support the use of prophylactic probiotics in preterm infants less than 2500 grams to reduce the incidence of NEC, as well as the use of human breast milk rather than formula when possible. There is no clear evidence to support delayed initiation or slow advancement of feeds. For surgical treatment of NEC with perforation, there is no clear support of peritoneal drainage versus laparotomy. Similarly, there is a lack of evidence comparing enterostomy versus primary anastomosis after resection at laparotomy. There are little data to determine the length of treatment with antibiotics to prevent recurrence of NEC. CONCLUSION Based on available evidence, probiotics are advised to decrease the incidence of NEC, and human milk should be used when possible. The other reviewed questions are clinically relevant, but there is a lack of evidence-based data to support definitive recommendations. These areas of NEC treatment would benefit from future investigation.

Abstract
OBJECTIVE The literature suggests that lung-head ratio (LHR) and liver position may inconsistently predict outcome for congenital diaphragmatic hernia (CDH). We reviewed our inborn neonates with isolated left-sided CDH to determine whether these variables predicted survival and to estimate the optimal LHR threshold. METHODS Prenatal LHR and liver position were obtained from 2002 to 2009. The primary endpoint was survival. RESULTS LHR was greater in survivors after adjusting for gestational age (median 1.40 versus 0.81; p < 0.001). LHR demonstrated excellent diagnostic discrimination, with area under receiver operating characteristic (ROC) curve 0.93 (95% CI 0.86-0.99). LHR threshold of 1.0 was 83% sensitive and 91% specific in predicting survival. An optimal LHR threshold of 0.85 predicted survival with 95% sensitivity and 64% specificity, reducing false negatives (survivors with low LHR). LHR > 0.85 predicted survival after adjustment for gestational age (OR = 33.6, 95% CI = 5.4-209.5). Liver position did not predict survival. CONCLUSIONS Prenatal LHR >0.85 predicts survival for infants with isolated left-sided CDH without compromising discrimination of survivors from non-survivors. The diagnostic utility of LHR may be confounded by gestational age at measurement. Stringent LHR threshold may minimize false-negative attribution and improve utility of this measurement as predictor of survival.

Abstract
PURPOSE The aim of this study is to review the current evidence-based data regarding strategies for prevention of central venous catheter (CVC) infections at the time of catheter insertion and as a part of routine care. METHODS We conducted a PubMed search from January 1990 to November 2010 using the following keywords: central venous catheter, clinical trials, pediatric, infection, prevention, antibiotic, chlorhexidine, dressing, antiseptic impregnated catheters, ethanol lock, impregnated cuff, insertion site infection, and Cochrane systematic review. Seven questions, selected by the American Pediatric Surgical Association Outcomes and Clinical Trials Committee, were addressed. RESULTS Thirty-six studies were selected for detailed review based on the strength of their study design and relevance to our 7 questions. These studies provide evidence that (1) chlorhexidine skin prep and chlorhexidine-impregnated dressing can decrease CVC colonization and bloodstream infection, (2) use of heparin and antibiotic-impregnated CVCs can decrease CVC colonization and bloodstream infection, and (3) ethanol and vancomycin lock therapy can reduce the incidence of catheter-associated bloodstream infections. CONCLUSION Grade A and B recommendations can be made based on available evidence in adult and limited pediatric studies for multiple components of proper CVC insertion practices and subsequent management. These strategies can minimize the risk of CVC infections in pediatric patients.

Abstract
Innovative treatments and procedures are essential to the advancement of surgery. Outcomes research provides the mechanism to analyze these new treatments as they enter clinical practice and evaluate them against established therapies. Information gained through this methodology is essential because new techniques and innovations often gain rapid acceptance before clinical trials can be conducted to assess them. Increasing national emphasis is placed on comparative effectiveness as health care costs rise. Surgeons must take the lead in surgical outcomes and comparative effectiveness research, with the goal of identifying the most efficient and effective treatment for our patients. The authors show how to structure and design a research project involving pediatric surgical outcomes. The model consists of the following 3 phases: (1) study design, (2) data preparation, and (3) data analysis.

Abstract
PURPOSE Extracorporeal Life Support Organization Registry data confirm that the number of pediatric patients being supported by extracorporeal membrane oxygenation (ECMO) is increasing. To minimize the potential neurologic effects of carotid artery ligation, the common femoral artery (CFA) is frequently being used for arterial cannulation. The cannula has the potential for obstructing flow to the lower limb, thus increasing ischemia and possible limb loss. We present a single institution's experience with CFA cannulation for venoarterial (VA) ECMO and ask whether any precannulation variables correlate with the development of significant limb ischemia. METHODS We reviewed all pediatric patients who were supported by VA ECMO via CFA cannulation from January 2000 to February 2010. Limb ischemia was the primary variable. The ischemia group was defined as the patients requiring an intervention because of the development of lower extremity ischemia. The patients in the no-ischemia group did not develop significant ischemia. Continuous variables were reported as medians with interquartile ranges and compared using Mann-Whitney U tests. Differences in categorical variables were assessed using χ² testing (Fisher's Exact). Statistical significance was assumed at P < .05. RESULTS Twenty-one patients (age, 2-22 years) were cannulated via the CFA for VA ECMO. Significant ischemia requiring intervention (ischemia group) occurred in 11 (52%) of 21. In comparing the 2 groups (ischemia vs no ischemia), no clinical variables predicted the development of ischemia (Table 1). In the ischemia group, 9 (81%) of 11 had a distal perfusion catheter (DPC) placed. Complications of DPC placement included one case of compartment syndrome requiring a fasciotomy and one patient requiring interval toe amputation. Of the 2 patients in the ischemia group who did not have a DPC placed, 1 required a vascular reconstruction of an injured superficial femoral artery and 1 underwent a below-the-knee amputation. Mortality was lower in the ischemia group (27% vs 60%). CONCLUSIONS Limb ischemia remains a significant problem, as more than half of our patients developed it. The true incidence may not be known as a 60% mortality in the no-ischemia group could mask subsequent ischemia. Although children are at risk for developing limb ischemia/loss, no variable was predictive of the development of significant limb ischemia in our series. Because of the inability to predict who will develop limb ischemia, early routine placement of a DPC at the time of cannulation may be warranted. However, DPCs do not completely resolve issues around tissue loss and morbidity. Prevention of limb ischemia/loss because of CFA cannulation for VA ECMO continues to be a problem that could benefit from new strategies.

Abstract
OBJECTIVE There is lack of data relating to the research interests and funding of pediatric surgeons within the United States and Canada. These data may be helpful in promoting basic and clinical research among pediatric surgeons. METHODS The American Pediatric Surgical Association (APSA) Outcomes and Clinical Trials Committee developed and administered an online survey via e-mail to the APSA membership to help characterize research activities and funding. The survey was available for completion during December of 2009. The survey contained 10 items with a drop-down menu for multiple choice answers and required 5 to 10 minutes to complete. Results based on research interests as well as funding sources were compiled and analyzed. RESULTS A total of 275 members, which comprises 27.4% of the APSA membership, completed the survey. Of the respondents, 177 (64%) described being in an academic practice, 44 (16%) in an academically associated private practice, 9 (3.3%) in a private solo practice, 17 (6.2%) in private group practice, and 3 (1%) in the military. A total of 189 (68.7%) respondents stated that they participated in formal research. Respondents also categorized their research interests, and the following were the most common subjects of study (decreasing order of frequency): appendicitis, trauma and critical care, outcomes, minimally invasive surgery, and congenital diaphragmatic hernia. Of those participating in research, 64.5% stated that they have no formal financial support. Of those supported through the National Institutes of Health, funding grants achieved were as follows: R01 (n = 29), K08 (n = 9), K23 (n = 2), and U01 (n = 8). CONCLUSIONS Research activities are common among APSA members and encompass a wide range of pediatric surgery topics. Strikingly, the overall financial support of these efforts is limited, predominantly supported by the surgeons themselves. Funded respondents attained grants through Public Health Service grants, departmental grants, or private institutions.

Abstract
BACKGROUND/PURPOSE Indications for a laparoscopic approach in the management of biliary atresia and choledochal cysts in children are not clearly defined. We present our initial experience with 9 consecutive laparoscopic cases, and compare them to the traditional open approach. METHODS A retrospective comparison of all consecutive operations for biliary atresia and choledochal cysts from January 2000 to May 2006 was undertaken. We evaluated the patient's age at operation, operative time, return of bowel function postoperatively, length of hospital stay, complications, and the need for subsequent liver transplantation. Mann-Whitney U test was used for statistical analysis. RESULTS A total of 45 portoenterostomies and choledochojejunostomies were performed, including 9 laparoscopic and 36 open procedures. Patients with choledochal cysts were older than patients with biliary atresia. All the compared parameters were similar and there was no difference in outcomes between the laparoscopic and the open groups. CONCLUSIONS Our initial experience is encouraging and indicates that the laparoscopic approach is technically feasible, safe, and effective, with a low morbidity and a comparable outcome to the open technique. Longer follow-up of a larger patient cohort is needed.

Abstract
Hypertrophic pyloric stenosis (HPS) is a common condition affecting infants that presents with progressive projectile nonbilious vomiting. The pyloric portion of the stomach becomes abnormally thickened and manifests as gastric outlet obstruction. The cause is unknown. Pyloromyotomy remains the standard of treatment and outcome is excellent. This article reviews the diagnostic work up and imaging, preoperative resuscitation, the various surgical approaches used, and the effect of subspecialty training on outcomes after pyloromyotomy. Postoperative care and the variety of postoperative feeding regimens applied after pyloromyotomy are reviewed, as well as intra- and postoperative complications. Finally, medical management, in lieu of surgery, is discussed.

Abstract
We sought to determine whether duodenum-preserving pancreatic head resections (DPPHRs) offer improved outcomes for benign disease of the proximal pancreas. A single-cohort study was performed of 86 consecutive patients who underwent DPPHR, extended lateral pancreaticojejunostomy with excavation of the pancreatic head (ELPJ), standard or pylorus-sparing Whipple procedure (WHIP), or distal pancreatectomy (DPR). Aspects of cost, complications (mortality and morbidity), and outcomes were assessed during a follow-up period of 6-63 months (mean, 3 years). Twelve DPPHR and 12 ELPJ procedures were performed for benign lesions or chronic pancreatitis (CP), as were 7 of 30 WHIP procedures and 12 of 16 DPRs. Operative time was significantly less than that for WHIP in ELPJ and DPR procedures. Major complications occurred in 40% of WHIPs and 25% of DPPHRs but only 16% of ELPJs (P < 0.05). Thirty-day mortality was 2 of 30 for WHIP but 0 for all other procedures. Pancreatic or biliary leak occurred in 3 of 30 WHIPs, 3 of 12 DPPHRs, 1 of 16 DPRs, and 0 of 12 ELPJs. New diabetes occurred in 25% of patients who underwent WHIP but only 8% of both DPPHR and ELPJ patients. Full functional recovery was similar for CP patients in both DPPHR and ELPJ. DPPHR and ELPJ are effective surgical approaches to the treatment of benign tumors and CP and are safer than WHIP with lower morbidity and mortality risks. The incidence of new diabetes is less with both ELPJ and DPPHR.

Abstract
Perforation of the gallbladder with spillage of stones into the abdominal cavity is relatively common during laparoscopic cholecystectomy. We report a patient presenting with a symptomatic groin hernia 10 days after laparoscopic cholecystectomy for acute cholecystitis. The hernia sac was found to contain a gallstone. The patient underwent an uneventful hernia repair. Various complications due to retained gallstones have been described as case reports emphasizing how important it is to prevent perforation of the gallbladder or else make an effort to retrieve spilled stones from the abdomen.

Abstract
Chronic pancreatitis (CP) is associated with impaired glucose tolerance and with reduced hepatic sensitivity to insulin. We have previously shown that in normal and sham-operated rats, insulin suppresses hepatic glucose production, and this suppression is associated with a decrease in the hepatocyte plasma membrane-bound quantity of the facilitative glucose transport protein GLUT2. The insulin-mediated reduction in membrane-bound GLUT2 is impaired in CP, and may play a role in the glucose intolerance associated with CP. To determine whether GLUT2 is actively internalized and whether this mechanism is disordered in CP, livers from fed and fasting rats in whom CP had been induced 2-3 months earlier by pancreatic duct oleic acid infusion, and in sham-operated (sham) rats, were fractionated to yield endosome (E)- and plasma membrane (PM)-enriched fractions. Forty-five minutes after duodenal intubation alone (fasting) or intubation plus duodenal feeding, livers were removed, homogenized and ultracentrifuged, and microsomal pellets were separated by sucrose density gradient ultracentrifugation. GLUT2 content of fractions was determined by Western blotting and scanning densitometry. The E:PM ratio of GLUT2 increased from 0.68 +/- 0.11 (mean +/- SEM) in fasting sham livers (n = 8) to 1.04 +/- 0.09 in fed sham livers (n = 8; p < 0.05). However, there was no change in the E:PM ratio of GLUT2 in CP livers after duodenal feeding (0.90 +/- 0.12 vs. 0.86 +/- 0.10; n = 8,8; p = NS). To test our findings using confocal laser scanning microscopy, liver specimens from fed and fasting CP and sham rats were minced, fixed in 4% paraformaldehyde, sectioned, and stained with rabbit antirat GLUT2 antibody followed by rhodamine-labeled secondary antibody. GLUT2 was quantified by mean pixel intensity in an 8 x 16-pixel area of PM and a 16 x 16-pixel area of cytosol (CYT) in each of 30 random cells/field (400x) in each of three rats per group. As in the fractionation study, duodenal feeding increased the CYT:PM ratio of GLUT2 from 0.75 +/- 0.01 in fasting sham liver to 0.86 +/- 0.01 in fed sham liver (p < 0.0001), while the CYT:PM ratio in CP remained unchanged. We conclude that feeding induces a shift in GLUT2 from the plasma membrane to the endosomal pool. The feeding-induced internalization of GLUT2 is absent in livers from rats with CP and may play a role in the glucose intolerance associated with CP.

Abstract
BACKGROUND Hepatic innervation plays an essential role in insulin extraction and glucose production, but the specific role of hepatic cholinergic innervation remains unclear. We sought to establish a model of isolated hepatic cholinergic denervation (IHCD), and to assess whether glycogen storage or the control of net hepatic glucose production (HGP) was altered by IHCD. MATERIALS AND METHODS Sprague-Dawley rats underwent either hepatic vagotomy or sham operation. Liver tissue was stained for vesicular acetylcholine transporter (VAChT) and (nonspecific neural) protein gene product 9. 5 (PGP) for verification of IHCD. Liver glycogen content was quantified in fed and fasted IHCD or sham-operated animals. HGP was determined after single-pass isolated liver perfusion, during which a 30-min 12 ng/ml glucagon infusion was begun after equilibration, and after 10 min, a 200 microU/ml insulin infusion was added. RESULTS Uniform staining of PGP and absence of VAChT staining in hepatic vagotomized rats demonstrated the validity of our model. Glycogen content of sham-operated livers (n = 8) increased from 6.0 +/- 1.7 in the fasting state to 10.6 +/- 1.8 mg/g liver, after feeding (P < 0.05). IHCD livers (n = 8) showed no comparable increase (3.5 +/- 0.6 to 4.0 +/- 0.7 mg/g liver). Perfusion with glucagon alone resulted in less HGP in IHCD livers (n = 12) compared with sham-operated livers (n = 10) (integrated HGP 3.3 +/- 0.3 mg/g liver min(-1) vs 5.1 +/- 0.5 mg/g liver min(-1), P < 0.05). Insulin infusion revealed impaired responsiveness to insulin after IHCD; the ratio of HGP in the final 10 min of perfusion (glucagon and insulin) to HGP in the initial 10 min (glucagon alone) was 90.3 +/- 2.4% for IHCD livers versus 68.1 +/- 4.4% for sham-operated controls, respectively (P = 0.0002). CONCLUSIONS Our study shows that IHCD results in significant impairment in liver glycogen storage and impaired hepatic sensitivity to glucagon and, possibly, to insulin. We conclude that hepatic cholinergic integrity is essential to normal hepatic glucose metabolism.

Abstract
The docking and fusion of membrane-bound vesicles at the cell plasma membrane are brought about by several participating vesicle membrane, plasma membrane, and soluble cytosolic proteins. An understanding of the interactions between these participating proteins will provide an estimate of the potency and efficacy of secretory vesicle docking and fusion at the plasma membrane in cells of a given tissue. Earlier studies suggest that in chronic pancreatitis, glucose intolerance may be associated with impaired exocytosis/endocytosis of hepatic insulin receptor and glucose transporter proteins. In this study, the binding force profiles between microsome membrane proteins and plasma membrane proteins in liver obtained from normal and pancreatitic rats have been examined using atomic force microscopy. The ability of a VAMP-specific antibody to alter binding between microsome- and plasma membrane-associated membrane proteins was examined. In pancreatitic livers, a significant loss in microsome-plasma membrane binding is observed. Furthermore, our study shows that, in contrast to control livers, the microsome-plasma membrane binding in pancreatitic livers is VAMP-independent, which suggests an absence of VAMP participation in membrane-microsome binding. In confirmation with our earlier findings, these studies suggest altered membrane recycling in liver of rats with chronic pancreatitis.

Abstract
The American College of Rheumatology (ACR) classification criteria were used to define the prevalence of clinical hand osteoarthritis (OA) in an elderly population in Iceland. The prevalence of hand OA was 3.3% for men and 6.8% for women, however, 19.6% of the men and 32.0% of the women fulfilled the ACR examination but lacked required symptoms. The prevalence of clinical signs of OA in the interphalangeal joints were similar for both sexes but were much more common in the first carpometacarpal joint of women (31.3% vs. 1.0% in men, p < 0.0001). No differences were observed between former seamen (55% of the men) and nonseamen or between the right and left hand. Intra- and interobserver agreement in diagnosis ranged from 83% to 97%, but only 70% of subjects fulfilling the symptoms criterion fulfilled the same criterion six months later. Our results suggest that the present symptoms criterion of the ACR clinical criteria restricts their use in population surveys, being both insensitive and unstable over time.
