A Comparative Analysis of Quality of Life in Children Managed for Omphalocele and Gastroschisis.

BACKGROUND: Evaluation of quality of life (QoL) in paediatric surgical patients has not always received enough attention in the past. Our aim was to follow up patients with abdominal wall defects for a decade and (1) to analyse children's view on QoL and to analyse parent's view on QoL, (2) to evaluate satisfaction and psychological problems, (3) to assess present complaints including subjective aspects such as food intake, reduced appetite, pain in scar area and general abdominal pain and (4) verifiable clinical symptoms assessed through a physical examination and ultrasound. It was hypothesised that QoL would differ from gastroschisis (GS) and omphalocele (OC) children depending on the type of abdominal wall defect. AIMS AND OBJECTIVES: A retrospective case-control design was used to compare children with GS (n = 36) and OC (n = 18). A clinical examination, including abdominal inspection, palpation and auscultation of bowel sounds with abdominal ultrasound, was offered, combined with a structured interview and specific QoL questionnaire (KINDL®). The focus was on QoL, child development, present complaints and satisfaction with the cosmetic outcome. RESULTS: During clinical examinations with ultrasound, GS children were significantly more likely to have bowel loops stuck at the scar area (P = 0.008) with bowel malrotation and abnormal appendix position, compared to OC children (P = 0.037). They were significantly more likely to report irregular stools (P = 0.02) but were satisfied with the cosmetic outcome of the abdominal skin scar in 81% of cases. The KINDL® evaluation showed in the dimensions of QoL, namely 'body awareness', 'mental health', 'self-esteem', 'family', 'friends' and 'school', that there were no significant differences to healthy children. OC/GS parents were satisfied with their children's physical development and QoL, noting no limitations in normal daily activities. Parents of OC children reported suffering from OC/GS-associated problems (P = 0.028) at the time point of interview. CONCLUSION: Subjective QoL did not differ significantly between OC and GS children. The satisfaction with the cosmetic outcome of the abdominal skin scar was good. On ultrasound examination, adherent bowel loops and bowel malrotation with resulting stool irregularities affect GS children. OC children's parents reported suffering from OC/OS-associated problems, and all parents need to be educated about the symptoms of recurrent sub-ileus events or atypical appendicitis.

Parental risk factors for oesophageal atresia.

BACKGROUND: An Oesophageal atresia (OA) affects almost 1 in 3500 newborn and its aetiology for development between 4th to 6th pregnancy weeks had not yet been clarified. METHODS: This retrospective, observational control group-supported (n = 30) examination was performed with OA mothers (n = 20) who were interrogated via specialized questionnaires and interviews to evaluate data on medical pregnancy history including hormonal treatment, changing of life habits (nutrition, diet, medication), drug consumption (alcohol, smoking, illicit drugs) as well as exposure to nuclear waste or poisonous substance exposition. Aim was to assess risk factors during pregnancy and in particular in the first trimester. RESULTS: The body mass index (BMI) prior pregnancy of OA mothers was significant lower (p = 0.022) and the number of mothers with obesity (BMI>30) did not differ to control group mothers (p = 0.081). They had additionally more pre-existing illnesses (p = 0.009) and allergies (p = 0.001). Control group mothers changed dietary habits with higher meat (p = 0.032) and caffeine intake (p = 0.012) compared to OA mothers, which had higher rates of abnormalities during pregnancy (p < 0.001) and 38.7% of them suffered of ≥1 abortion in the past. The ethnical background of OA mothers was more often German (p < 0.033), while OA fathers had a lower socioeconomic status (p = 0.039). CONCLUSION: Maternal factors like previous abortions, obesity and immunological predispositions like existence of allergies combined with increased daily dairy consumption influenced obviously the occurrence of OA.

Does meconium contaminated amniotic fluid affect intestinal wall thickness and functional outcome in patients with anterior abdominal wall defects?

BACKGROUND: Gastroschisis (GS) and omphalocele (OC) are congenital abdominal wall defects, the main difference between is the direct exposure of intestinal loops in amniotic fluid in children with a GS. This leads to a reduced primary closure rate and a higher number of intraoperative abnormalities and post-operative complications. AIMS AND OBJECTIVES: We analysed abdominal wall defect patients over an 11-year period, aiming to assess the influence of meconium-contaminated amniotic fluid. This study has different objectives to show the consequence of functional outcome of abdominal wall defects (AWD) children in reliance to colour of amniotic fluid, to assess the effect of reduced bowel exposure time to meconium contaminated amniotic fluid on edematous inflammatory thickening of the bowel loops, to show an positively influence in the number of primary AWD closures, to demonstrate a reduced incidence of post-natal complications and to verify a better outcome of OC children because of failing exposure to amniotic fluid. METHODS: A retrospective, observational case-control design was used to compare GS (n = 36) and OC (n = 18) children. Physical data, colour of amniotic fluid, pre- and perinatal problems, operative complications and surgical technique, post-operative complications, duration of intensive care unit (ICU) stay, mechanical ventilation, parenteral nutrition, commencement of oral feeding and total hospital stay were collected. Data were analysed with descriptive methods, t-test and non-parametric tests such as Wilcoxon and Kruskal-Wallis were performed in addition to the analysis of variance, including post hoc testing accepting a confidence interval of 95% (P < 0.05) by using IBM SPSS software, version 23 (IBM, Illinois, USA). RESULTS: Rate of meconium-contaminated amniotic fluid is significantly higher in GS compared to OC (P < 0.001), delivery problems such as congenital infections are also significantly higher (P < 0.001), this yields in significantly more bowel loops anomalies and problems during surgery (P < 0.036) but had no significant influence on primary abdominal wall closures rate (P = 0.523). The post-surgical outcome of OC was significantly better as compared to GS. Within the GS, those with swollen intestines had significantly longer ICU stays (P = 0.045) due to extended mechanical ventilation (P = 0.007), parenteral nutrition (P = 0.011) and delayed initiation of oral feeding (P < 0.001. Same results were found for the duration of ICU stay (P = 0.008), mechanical ventilation (P = 0.006), parenteral nutrition (P = 0.011) and delayed initiation of oral feeding (P < 0.001) in secondary closures as compared to primary abdominal wall closures in the GS group. CONCLUSIONS: Worsen functional short-term outcome of GS children was directly addicted to meconium contamination of amniotic fluid due to swollen intestines and because of this more post-surgical problem including significantly extended hospital stays were observed.

Risk factors for anorectal and associated malformations in German children: A 10-year analysis.

BACKGROUND: Incidences of anorectal malformations (ARM) occur in 1 of 2000-5000 live births and up to 64% have associated malformations (ARMa). The aim of the study was to evaluate possible prenatal risk factors for ARM in a tertiary hospital. METHODS: A case-control design was used to compare risk factors in ARM (n = 44) to a control group (CG; n = 26). We used modified prenatal questionnaires, analyzed mothers' prenatal records and participants completed a structured interview. Endpoints were medical history, drug consumption, occupational risk factors, and time point of diagnosis, associated malformations and sensitivity of radiological imaging. RESULTS: Our results showed that ARM couples had a significantly higher age difference (p = 0.028) compared to CG. ARM mothers had more abnormalities during pregnancy (p = 0.002), more positive vaginal smears of group B streptococci (p = 0.024), urogenital infections (p = 0.005), gestosis (p = 0.03), emesis (p = 0.025) and higher numbers of chronic diseases (p = 0.018). ARM mothers took less medication during pregnancy (p = 0.013) than CG mothers including folic acid (p = 0.041); their intake of iodine tablets was significantly higher (p = 0.035) and they continued smoking for longer (p = 0.036) than CG mothers, and they had more stillbirths (p = 0.035). In using illegal drug and alcohol use, the groups did not show significant differences. ARMa was present in 68.1% (n = 30), of which 45.5% were of urogenital origin (n = 20). ARM diagnosis was made on the first day of life in 72.7% (n = 32), while diagnosis was delayed in 12 patients (27.3%). CONCLUSION: A combination of different risk factors seem to be associated with the development of ARM, which takes place at an early stage (<7th week) of pregnancy. Therefore, risk factors influencing fetal development must be critically considered. We advocate an interdisciplinary assessment in unclear clinical findings on first day of life to optimize the therapy and positively influence the outcome.

Risk factors for abdominal wall defects.

In the last decades, the prevalence of gastroschisis (GS) has increased worldwide. The purpose of this study was to identify maternal risk factors explaining the described gain and to identify differences between GS and omphalocele (OC). A case-control design was used to compare GS (n = 36) and OC (n = 18) mothers to control group (CG; n = 30) matched for maternal age. Specialized questionnaires and mothers' prenatal records were used, and participants completed a structured interview. Focus was on medical history, changing nutrition, drug consumption, and external risk factors. The local ethics committee approved this study. GS mothers were significantly younger (mean 23.00; median 24; SD ±5) than OC (P = 0.007; mean 28.61; median 28, 19-41; SD ±5.1) and CG (P = 0.001; mean 30.77; median 31, SD ±6.2). Mothers with abdominal wall defects (AWD) ingested antibiotics more often (P = 0.008) than CG. Socioeconomic characteristics, for example, level of profession, of GS mothers was significantly lower than OC (P = 0.039) and CG (P = 0.05) mothers, and their cohabitation time was shorter (P < 0.05; mean 35 month/median 24 month, SD ±35.8). Incidence of OC significantly increased after hormonal treatment (P = 0.022) and invasive prenatal diagnostics (P < 0.05) compared to GS. GS mothers took folic acid prophylaxis less often than OC (P = 0.02). Smoking, illicit drugs, and external risks like herbicides showed no influence, but GS mothers drink significantly more often alcohol (P = 0.05). We confirmed an increased risk for GS if several factors such as young maternal age, short cohabitation time, and usage of antibiotics coincide with alcohol consumption and associated immune diseases. OC increased after hormonal treatment and invasive prenatal diagnostics.

Age- and BMI-Associated Expression of Angiogenic Factors in White Adipose Tissue of Children.

The growth of adipose tissue and its vasculature are tightly associated. Angiogenic factors have been linked to obesity, yet little is known about their expression during early childhood. To identify associations of angiogenic factors with characteristics on individual and tissue level, subcutaneous white adipose tissue samples were taken from 45 children aged 0-9 years undergoing elective surgery. We measured the expression of vascular endothelial growth factor A (VEFGA), fibroblast growth factor 1 and 2 (FGF1, FGF2), angiopoietin 1 and 2 (ANGPT1, ANGPT2), TEK receptor tyrosine kinase (TEK), and von Willebrand factor (VWF). In addition, we determined the mean adipocyte size in histologic tissue sections. We found positive correlations of age with FGF1 and FGF2 and a negative correlation with ANGPT2, with pronounced differences in the first two years of life. FGF1, FGF2, and ANGPT1 correlated positively with adipocyte size. Furthermore, we identified a correlation of ANGPT1 and TEK with body mass index-standard deviation score (BMI-SDS), a measure to define childhood obesity. Except for ANGPT2, all angiogenic factors correlated positively with the endothelial marker VWF. In sum, our findings suggest that differences related to BMI-SDS begin early in childhood, and the analyzed angiogenic factors possess distinct roles in adipose tissue biology.

Head Injury in Children: Has a Change in Circumstances Caused an Increase in Treatment Numbers?

The number of hospitalizations for head injuries in children is rising. The exact causes remain unclear. We analyzed data of children aged between 0 and 18 years who sustained a head injury between 2010 and 2011. The analysis focused on data related to demographics, trauma mechanism, clinical course, results of imaging scans, concomitant injuries, and outcome. A total of 794 inpatient cases of head injury were treated. The leading mechanism of injury was a fall (at home) primarily at the age of 1 to 4 years (46.5%), with the majority of the children sustaining a mild brain injury (764, 96.2%). Neurosurgery was performed in 21 (2.64%) cases; average hospital stay was 2.9 days (range: 0-68 days). This study is not able to confirm that children are increasingly being brought to the hospital by their parents because of new trauma mechanisms or parents' uncertainty, nor can we confirm that the number of nonaccidental injuries is rising.

Prolonged postsurgical recovery period and adverse effects of a leptin application in endotoxemic obese rodents.

AIMS: Increasing evidence suggests that the adipokine leptin plays a role in modulating immune responses and mediating the link between metabolism and immune system. Obese patients are more susceptible to infections than normal weight individuals. To define the pathophysiological role of leptin during endotoxemia, we examined the effects of leptin on energy metabolism, hemodynamics and quality of life in normal weight and diet-induced obese rats by means of radio-telemetry. MAIN METHODS: Telemetric-transmitter and a central venous catheter were implanted in male Lewis rats. All animals performed two experiments. First, an intravenous injection of 500µlkg(-1) leptin or vehicle (isotonic saline) was performed. After an infusion time of 30min an i.v. bolus of 0.2ml saline over 1min was injected. In the second phase, infusion of placebo or 500µlkg(-1) leptin and an i.v. bolus injection of 100µlkg(-1)Escherichia coli endotoxin were performed. Mean arterial blood pressure (MAP), locomotor activity and electromyogram were recorded via radio-telemetry. Food and water consumption were assessed daily. Quality of life tests were performed at specific times. KEY FINDINGS: Obese animals displayed a prolonged postsurgical recovery period. No benefit could be observed by exogenous leptin in endotoxemic lean or obese animals regarding nutrition balance and locomotor activity. However, leptin treatment even destabilized MAP in obese endotoxemic animals. SIGNIFICANCE: These data demonstrate the necessity to differentiate between normal weight and obese individuals when targeting novel therapeutic strategies for endotoxemia and point out the body weight dependent postsurgical recovery period.
