Enough is enough: how many rectal suction biopsies do you need to diagnose Hirschsprung's disease?

PURPOSE: Rectal suction biopsy (RSB) is the gold standard for diagnosing Hirschsprung's disease (HD) in infants. Despite being a common procedure, no standard exists on the number of biopsy specimens and their respective level within the rectum. METHODS: We conducted a retrospective review of epidemiological and pathological data of patients who underwent RSB at our institution between January 2011 and May 2022. During RSB we obtain 4 specimens: at 1 cm, 3 cm and 5 cm above the dentate line, besides one specimen at the dentate line. We used a logistic regression model for statistical analysis and included control variables (e.g. underlying disease, weight at first biopsy, gestational age). RESULTS: A total of 92 patients underwent 115 biopsies, with an average of 3.77 specimens per session. Of the specimens taken at 1 cm above the dentate line 73.9% were conclusive, at 3 cm 75.9% and at 5 cm 79.2%. Specimens taken at the dentate line were squamous or transitional epithelia in 31.5% and therefore of no use for HD diagnostics. The specimen at 3 cm shows the highest discriminative power whether the biopsy session was diagnostic (p-value < 1%). CONCLUSIONS: We propose that a total of three specimens, namely one at 1 cm, one at 3 cm and one at 5 cm above the dentate line, is enough to diagnose or exclude HD.

Fetal surgery for spina bifida in Zurich: results from 150 cases.

PURPOSE: Over the past 10 years, over 150 fetal spina bifida surgeries were performed at the Zurich Center for Fetal Diagnosis and Therapy. This study looks at surrogates for success and failure of this approach. METHODS: We focused on key outcome parameters including hydrocephalus shunt rate at one year, bladder control at 4, independent ambulation at 3 years, and maternal, fetal, and neonatal complications. RESULTS: From the first 150 patients undergoing fetal surgery for spina bifida, 148 (98.7%) were included in the study. Maternal-fetal surgery was uneventful in 143/148 (97%) cases. Intraoperative problems included resuscitation in 4/148 fetuses (2.7%). 1/148 fetuses (0.7%) died on postoperative day 4. Maternal complications included chorioamniotic membrane separation in 22/148 (15%), lung embolism in 3/148 (2.1%), chorioamnionitis in 2/148 (1.4%), AV-block III and uterine rupture in 1/148 each (0.7%). 1/148 (0.7%) newborn death was recorded. Hindbrain herniation was identified preoperatively in 132/148 (90%) fetuses and resolved completely in 119/132 (90%). At one year, 39/106 (37%) children had required a CSF diversion. At 4 years, 4/34 patients (12%) had normal bladder control. At 3 years, 48/57 (84%) walked independently. CONCLUSION: A majority of patients benefitted from prenatal intervention, in that the shunt rate was lower and the rates of continent and walking patients were higher than reported with postnatal care.

Abdominal compartment syndrome and decompressive laparotomy in children: a 9-year single-center experience.

PURPOSE: Abdominal compartment syndrome (ACS) in children results in 100% mortality if left untreated. Decompressive laparotomy (DL) is the only effective treatment if conservative medical therapies have failed. This study aims to determine the incidence of ACS among pediatric patients who underwent an emergency laparotomy (EL), to describe the effect of DL on clinical and laboratory parameters and, to make a better prediction on fatal outcome, to analyze variables and their association with mortality. METHODS: This retrospective study includes 418 children up to the age of 16 years who underwent EL between January 2010 and December 2018 at our tertiary pediatric referral center. ACS was defined according to the latest guidelines of the World Society of the Abdominal Compartment Syndrome. RESULTS: Fourteen patients had emergency DL for ACS. 6 h preoperatively; median intra-abdominal pressure (IAP) and abdominal perfusion pressure (APP) were 22.5 mmHg and 29 mmHg, respectively. After DL, IAP decreased and APP increased, both by an average of 60%. Six patients survived, eight patients had a fatal outcome, resulting in a mortality of 57%. An age under 1 year, weight under the 3rd percentile, an open abdomen treatment, an intestinal resection and an elevated serum lactate > 1.8 mmol/L were associated with an increased relative risk of death. CONCLUSIONS: Improving the outcome in pediatric patients with ACS by removing or attenuating risk factors is difficult. This emphasizes the need for early diagnosis and prompt DL once the diagnosis of ACS is made.

In utero Plastic Surgery in Zurich: Successful Use of Distally Pedicled Random Pattern Transposition Flaps for Definitive Skin Closure during Open Fetal Spina Bifida Repair.

BACKGROUND: One of the intraoperative challenges of fetal spina bifida repair is skin closure when there is an extended skin defect. Thus, we examined whether distally pedicled random pattern transposition flaps (TFs) are a valid option to overcome this problem. SUBJECTS AND METHODS: All patients undergoing in utero repair of spina bifida with application of a TF for back skin closure were analyzed focusing on intraoperative flap characteristics and postoperative flap performance. RESULTS: In 30 (70%) of the 43 fetuses a primary skin closure was achieved, in 5 (12%) a skin substitute was used, and in 8 (18%) a TF was applied. Flap raising and insertion was uneventful and perfusion was sufficient in all 8 fetuses (100%). In 3 fetuses (37%) the donor sites were closed primarily, and in 5 (63%) a skin substitute was used for coverage. At birth, 7 flaps were viable and provided robust skin coverage over the center of the former lesion. Complications included a small skin defect with CSF leakage in 1 patient (13%). CONCLUSION: During open fetal spina bifida repair, TFs can be safely and efficaciously used to obtain solid and durable skin coverage over lesions too large to allow conventional primary skin closure.

Hydroxyapatite ceramic implants for cranioplasty in children: a single-center experience.

PURPOSE: The use of hydroxyapatite ceramic (HAC) implants for the treatment of skull defects in pediatric patients started 2010 at our institution. Ceramic implants facilitate osteoblast migration and therefore optimize osteointegration with the host bone. The purpose of this study is to report a single-center experience with this treatment modality. METHODS: A retrospective review of all patients from July 2010 through June 2014 undergoing a cranioplasty using hydroxyapatite ceramic implant and managed at a single institution was performed. Indication for cranioplasty, the hospital course, and follow-up were reviewed. Bone density was measured in Hounsfield Units (HU) and osteointegration was calculated using Mimics Software® (Mimics Innovation Suite v17.0 Medical, Materialize, Leuven, Belgium). RESULTS: Over the 4-year period, six patients met criteria for the study. Five patients had an osteointegration of nearly 100%. One patient had an incomplete osteointegration with a total bone-implant contact area of 69%. The mean bone density was 2800 HU (2300-3000 HU). Bone density alone is estimated to have a Hounsfield value between 400 and 2000 HU depending on the body region and bone quality. There were no major complications, and the patients were highly satisfied with the esthetical result. CONCLUSION: Hydroxyapatite ceramic implants for cranioplasty in pediatric patients are a good choice for different indications. The implants show excellent osteointegration and esthetical results.

Failed Intussusception Reduction in Children: Correlation Between Radiologic, Surgical, and Pathologic Findings.

OBJECTIVE: The objective of this study was to identify causes of irreducible intussusception after contrast enema and to correlate imaging findings with surgical and histopathologic findings. MATERIALS AND METHODS: Between 2005 and 2013, a total of 543 children underwent reduction of intussusception with the use of an enema technique (hereafter referred to as "enema reduction"). The medical records of 72 children (56 boys [mean age, 24.8 months; range, 3.8 months to 10.9 years] and 16 girls [mean age, 14.2 months; range, 1.5 months to 6.9 years) who underwent unsuccessful reduction and were treated surgically were retrospectively analyzed. The data collected included information on the cause of intussusception, the risk factors noted on ultrasound, operative management, outcome, and the length of the hospital stay. The imaging findings for these patients were compared with findings for statistically similar age-matched control subjects. RESULTS: Ultrasound detected 56 of 57 cases of intussusception, but it failed to detect the lead point in three cases and failed to detect ischemic necrosis in seven cases. Positive predictors of failed enema reduction were the presence of a distal mass and observation of the dissecting sign. Of the 72 patients who underwent surgical treatment of intussusception, 26 (36.1%) underwent laparoscopy, 38 (52.8%) underwent laparotomy, and eight (11.1%) underwent conversion from laparoscopy to laparotomy. Surgical reduction was performed in 61.1% of cases, small bowel resection in 19.4%, ileocecectomy in 12.5%, and self-reduction in 69%. Pathologic lead points (noted in 25% of cases) included lymphoid hyperplasia (n = 7), Meckel diverticulum (n = 3), Burkitt lymphoma (n = 3), enteric duplication cyst (n = 2), juvenile polyp (n = 2), and adenovirus appendicitis (n = 1). The length of the hospital stay was significantly longer after laparotomy. CONCLUSION: The distalmost location of the intussusception mass and presence of the dissecting sign on images obtained during contrast enema have a higher positive predictive value for failed reduction. Screening ultrasound decreases the number of unnecessary contrast enemas performed; however, classic pathologic lead points, such as Burkitt lymphoma and Meckel diverticulum, may be difficult to diagnose with the use of ultrasound. Laparotomy and laparoscopy are equally safe and efficacious in reducing intussusception, with the length of the hospital stay after laparoscopy significantly shorter than that noted after laparotomy. Most failed enema reductions are idiopathic, and pathologic lead points are noted in 25% of cases.

Vessel sealing comparison: old school is still hip.

BACKGROUND: Ligation with either absorbable or non-absorbable sutures has been the traditional state of the art, but a proliferation of technology now offers a host of methods to close and divide vessels. Only limited data are available that objectively compare different vessel sealing methods. The objective of this study was to compare a broad variety of methods of surgical vessel closure in a reproducible, independent, standardized test-to-failure ex vivo pressure challenge. METHODS: Ten of the most common surgical sealing devices were represented in this study, including both mechanical and energy devices. Unfixed porcine carotid arteries were selected for testing. They were connected to a pump, and automated controlled infusion was initiated. Upon identification of a leak at the source of sealing, the maximum pressure in mmHg was logged. RESULTS: There were a total of 184 trials conducted using the 10 vessel sealing methods. The average burst pressure across all trials was 1100 mmHg with a range of 51.3-5171 mmHg. Suture-based methods displayed the highest average pressure until failure. Stapling methods showed the lowest burst pressures. All methods showed mean burst pressures above the "physiologically relevant" level of 250 mmHg. CONCLUSIONS: This study presents an independent, reproducible, ex vivo comparison of multiple methods of surgical arterial closure. In these laboratory conditions, tests to failure demonstrated widely varying sealing strength, highly dependent on method. All hemostatic modalities tested are capable of securing vessels safely and well above physiologic blood pressures, while suture-based methods were significantly stronger than other mechanical methods or modern energy devices.

Utility of neurocognitive testing of mild traumatic brain injury in children treated and released from the emergency department.

PRIMARY OBJECTIVE: To assess feasibility and utility of neurocognitive testing of children evaluated and discharged from the ED with mild traumatic brain injury (MTBI). METHODS: Paediatric blunt trauma patients (aged 11-18 years) evaluated in the ED for MTBI and control patients with isolated lower extremity injury were prospectively enrolled. All patients were administered a validated neurocognitive test (ImPACT(©)). Wilcoxon sign rank tests were used to compare reported symptoms and neurocognitive performance between subjects and controls, as well as to matched normative data. RESULTS: Thirty-nine subjects and 46 controls were enrolled. The MTBI patients had a mean age of 13.9 years (53.8% male). An abnormal symptom score was reported in 89.7% of MTBI subjects (mean score = 29.4, normal ≤ 8), differing significantly (p < 0.05) from controls, in whom 39.1% demonstrated an abnormal score (mean score = 8.7). In all neurocognitive test domains, visual motor speed and reaction time, MTBI patients demonstrated lower scores than normative data (p < 0.05). CONCLUSIONS: Patients with MTBI were more likely than control subjects to have scores on any or all neurocognitive domains below the 25th percentile and 10th percentile. In the ED setting, acute neurocognitive testing of MTBI in children is feasible. This highlights the importance of structured follow-up for this treated and released population.

Compartment Pressures in Children With Normal and Fractured Forearms: A Preliminary Report.

INTRODUCTION: Acute compartment syndrome (ACS) can lead to irreversible damage if fasciotomy is not performed in a timely manner. Needle manometry is a tool to confirm suspected ACS. The threshold for compartment pressures that can be tolerated has been debated. The aim of this study is to assess the normal compartment pressures in noninjured forearms of children. Further, we sought to quantify the maximum tolerable compartment pressures in fractured forearms of children, thus establishing a baseline and providing guidance in evidence-based decision making to evaluate children with suspected ACS. METHODS: This prospective study included children up to the age of 16 years with forearm fractures that needed reduction with or without osteosynthesis. Between June 2009 and March 2013, 41 children were included. Mean age was 9.25 years (range, 4 to 15.4 y). We used needle manometry to measure the pressures in the superficial and deep volar as well as in the dorsal compartments (DCs) on both the forearms. The mean pressures between compartments in healthy versus injured arms were analyzed using a 1-sided, paired t test. RESULTS: On the injured side, the mean compartment pressure was 19.12 mm Hg (range, 3 to 49 mm Hg) in the deep volar compartment, 15.56 mm Hg (range, 5 to 37 mmHg) in the DC, and 14.8 mm Hg (range, 2 to 35 mm Hg) in the superficial volar compartment. On the noninjured side, the mean compartment pressure was 12.9 mm Hg (range, 6 to 31 mm Hg) in the DC, 10.22 mm Hg (range, 3 to 22 mm Hg) in the deep volar compartment, and 9.66 mm Hg (range, 3 to 21 mm Hg) in the superficial volar compartment. We measured an absolute compartment pressure of >30 mm Hg in 15 patients on the fractured side. Three of them had an absolute compartment pressure of >45 mm Hg. Only 1 had ACS. This patient underwent fasciotomy and was excluded for further analysis. On follow-up (mean, 24.84 mo), no patient was found to have any sequelae of ACS. DISCUSSION: This is the first study to report normal compartment pressure measurements in noninjured forearms and in fractured forearms without clinical suspicion of ACS in children.The mean compartment pressure measured in the deep volar compartment (DVC) in healthy children was 10.22 mm Hg (range, 3 to 22 mm Hg) and therefore slightly higher than in adults. Some children with fractures tolerated absolute compartment pressures >30 mm Hg without clinical signs of ACS. Fasciotomy in children under close observation could eventually be delayed despite surpassing the accepted pressure limits for adults. LEVEL OF EVIDENCE: Level I-prognostic.

Long-Term Outcomes and Health-Related Quality of Life in a Swiss Patient Group with Esophageal Atresia.

INTRODUCTION: Surgical treatment of esophageal atresia (EA) has markedly improved, allowing the focus to shift from short-term complications and mortality to long-term complications and quality of life. Health-related quality of life (HRQoL) is variable and reported to range from reduced to unimpaired in patients with repaired EA. We assessed the HRQoL, determined the prevalence of long-term complications and their possible impact on the HRQoL in patients who had correction of EA in Switzerland. Further, we also investigated in the general well-being of their parents. MATERIALS AND METHODS: Patients with EA repair in Switzerland between 1985 and 2011 were enrolled. Long-term complications were assessed by enquiring disease-related symptoms, standardized clinical examinations, and analysis of radiographs. HRQoL was inquired using different validated questionnaires (KIDSCREEN-27, World Health Organization [WHO]-5, and Gastrointestinal Quality of Life Index [GIQLI]). Patients were grouped according to their age. In underage patients, general well-being of the parents was assessed using the WHO-5 questionnaire. RESULTS: Thirty patients were included with a mean age of 11.3 ± 5.7 years. Long-term complications were present in 63% of all patients. HRQoL in underage patients was comparable to the provided reference values and rated as good, while adult patients reported a reduced HRQoL. The presence of gastroesophageal reflux disease symptoms was associated with reduced HRQoL in underage patients. Parents of underage patients stated a good general well-being. CONCLUSION: Long-term complications among patients with repair of EA in Switzerland are common. HRQoL in underage patients is good and general well-being of their parents is unimpaired. Adult patients reported a reduced HRQoL, consistent with other reports. As long-term complications may manifest only later in life, a structured follow-up of patients with an EA repair during childhood and adolescence is needed.

Cholinergic Signaling Attenuates Pro-Inflammatory Interleukin-8 Response in Colonic Epithelial Cells.

Infants affected by Hirschsprung disease (HSCR), a neurodevelopmental congenital disorder, lack ganglia of the intrinsic enteric nervous system (aganglionosis) in a variable length of the colon, and are prone to developing severe Hirschsprung-associated enterocolitis (HAEC). HSCR patients typically show abnormal dense innervation of extrinsic cholinergic nerve fibers throughout the aganglionic rectosigmoid. Cholinergic signaling has been reported to reduce inflammatory response. Consequently, a sparse extrinsic cholinergic innervation in the mucosa of the rectosigmoid correlates with increased inflammatory immune cell frequencies and higher incidence of HAEC in HSCR patients. However, whether cholinergic signals influence the pro-inflammatory immune response of intestinal epithelial cells (IEC) is unknown. Here, we analyzed colonic IEC isolated from 43 HSCR patients with either a low or high mucosal cholinergic innervation density (fiber-low versus fiber-high) as well as from control tissue. Compared to fiber-high samples, IEC purified from fiber-low rectosigmoid expressed significantly higher levels of IL-8 but not TNF-α, IL-10, TGF-ß1, Muc-2 or tight junction proteins. IEC from fiber-low rectosigmoid showed higher IL-8 protein concentrations in cell lysates as well as prominent IL-8 immunoreactivity compared to IEC from fiber-high tissue. Using the human colonic IEC cell line SW480 we demonstrated that cholinergic signals suppress lipopolysaccharide-induced IL-8 secretion via the alpha 7 nicotinic acetylcholine receptor (a7nAChR). In conclusion, we showed for the first time that the presence of a dense mucosal cholinergic innervation is associated with decreased secretion of IEC-derived pro-inflammatory IL-8 in the rectosigmoid of HSCR patients likely dependent on a7nAChR activation. Owing to the association between IL-8 and enterocolitis-prone, fiber-low HSCR patients, targeted therapies against IL-8 might be a promising immunotherapy candidate for HAEC treatment.

Lack of Mucosal Cholinergic Innervation Is Associated With Increased Risk of Enterocolitis in Hirschsprung's Disease.

BACKGROUND & AIMS: Hirschsprung's disease (HSCR) is a congenital intestinal motility disorder defined by the absence of enteric neuronal cells (ganglia) in the distal gut. The development of HSCR-associated enterocolitis remains a life-threatening complication. Absence of enteric ganglia implicates innervation of acetylcholine-secreting (cholinergic) nerve fibers. Cholinergic signals have been reported to control excessive inflammation, but the impact on HSCR-associated enterocolitis is unknown. METHODS: We enrolled 44 HSCR patients in a prospective multicenter study and grouped them according to their degree of colonic mucosal acetylcholinesterase-positive innervation into low-fiber and high-fiber patient groups. The fiber phenotype was correlated with the tissue cytokine profile as well as immune cell frequencies using Luminex analysis and fluorescence-activated cell sorting analysis of colonic tissue and immune cells. Using confocal immunofluorescence microscopy, macrophages were identified in close proximity to nerve fibers and characterized by RNA-seq analysis. Microbial dysbiosis was analyzed in colonic tissue using 16S-rDNA gene sequencing. Finally, the fiber phenotype was correlated with postoperative enterocolitis manifestation. RESULTS: The presence of mucosal nerve fiber innervation correlated with reduced T-helper 17 cytokines and cell frequencies. In high-fiber tissue, macrophages co-localized with nerve fibers and expressed significantly less interleukin 23 than macrophages from low-fiber tissue. HSCR patients lacking mucosal nerve fibers showed microbial dysbiosis and had a higher incidence of postoperative enterocolitis. CONCLUSIONS: The mucosal fiber phenotype might serve as a prognostic marker for enterocolitis development in HSCR patients and may offer an approach to personalized patient care and new therapeutic options.

Transglutaminases, involucrin, and loricrin as markers of epidermal differentiation in skin substitutes derived from human sweat gland cells.

BACKGROUND/PURPOSE: In a multi-project research line, we are currently testing whether a morphologically and functionally near normal epidermis can be cultured from human sweat gland (SG) cells and be used as a skin substitute. The present study focuses on the stratum corneum of the epidermis that assumes a vital barrier function for the skin. The main process in the formation of the cornified cell envelope in human epidermis, i.e. crosslinking of proteins and lipids, is catalyzed by several transglutaminases (TG). Therefore, we compared the expression patterns of various TG and their substrates in SG-derived versus keratinocyte-derived epidermal substitutes. METHODS: Sweat gland cells, keratinocytes, and fibroblasts were isolated from human skin samples and cultivated separately to generate epidermal substitutes. These were transplanted onto the back of athymic rats. After 2 weeks, the transplants were excised and analyzed histologically as well as by indirect immunofluorescence. We looked at the expression of TG1, 3, 5, and their substrates involucrin and loricrin (=markers of epidermal differentiation) in SG-derived and keratinocyte-derived skin substitutes as well as in normal skin. RESULTS: The SG cell-derived epidermis was near normal anatomically, formed a cornified cell envelope and demonstrated TG1, 3, and 5 as well as involucrin and loricrin expression patterns similar to those found in keratinocyte-derived epidermis and normal control skin. CONCLUSION: These findings support the thesis that SG cells have the potential to form a near normal stratified epidermal analog that might be used as a skin substitute. The expression of TG1 and 3, not normally expressed in human SG, suggests the presence of re-programmed SG cells and/or stem cells capable of both de novo generating and maintaining an epidermis.

Comparison of lower extremity fasciotomy wound closure techniques in children: vacuum-assisted closure device versus temporary synthetic skin replacement.

PURPOSE: No clear consensus on the optimal treatment of fasciotomy wounds due to acute compartment syndrome of the lower leg in children exists. We therefore compared two commonly used methods to close fasciotomy wounds, Epigard, a temporary synthetic skin replacement (SSR) and the vacuum-assisted closure (V.A.C.) device, in respect of treatment duration and complication rates. METHODS: We studied the cases of 27 patients who were treated at our institution for acute compartment syndrome of the lower leg with a fasciotomy over a 10-year period. The fasciotomy wound was either treated with SSR or V.A.C. device. We recorded the number of procedures to definitive wound closure, days to wound closure, hospitalization days and sequelae rate. RESULTS: In the V.A.C. device group (18 patients) the mean number of procedures until definitive wound closure was 3.1, mean days until wound closure was 9.4 and mean days of hospitalization was 16.2. One patient suffered from a wound infection and one patient required a full thickness skin graft. In the SSR group (9 patients), the mean number of procedures was 1.8, mean days until definitive wound closure was 4.9 and mean days of hospitalization was 9.9. No sequelae were recorded. There was a statistically significant smaller number of procedures (p value 0.018), fewer days to definitive wound closure (p value 0.002) and fewer hospitalization days (p value 0.005) in the SSR group. CONCLUSIONS: Both SSR and V.A.C. device are safe and reliable for closure of fasciotomy wounds in children, whereas SSR seems to lead to shorter time until definitive wound closure.

Compartment pressures in children with normal and fractured lower extremities.

PURPOSE: Needle manometry is a tool to confirm suspected acute compartment syndrome (ACS). There is scarce evidence of normal pressure values of the lower extremities in children. The aim of this study is to assess the normal compartment pressures in non-injured lower extremities of children. METHODS: This prospective study included children up to the age of 16 years with lower extremity fractures that needed reduction. Between June 2009 and August 2015, 20 children were included. We used needle manometry to measure the pressures in the superficial (SPC), deep posterior (DPC) and in the anterior compartments (AC) on both the lower legs. RESULTS: On the healthy leg, the mean compartment pressure was 15.15 mmHg in the AC (range 7-30 mmHg), 14.32 mmHg in the SPC (range 8-24 mmHg) and 13.00 mmHg in the DPC (range 4-21 mmHg). On the injured leg, the mean compartment pressure was 24.07 mmHg in the AC (range 5-40 mmHg), 17.21 mmHg in the SPC (range 7-29 mmHg) and 17.13 mmHg in the DPC (range 6-37 mmHg). We found a perfusion gradient (diastolic blood pressure-compartment pressure) < 30 mmHg in at least one compartment of the fractured and healthy leg in 13 patients. Five patients underwent fasciotomy for suspected ACS and their data was excluded for the injured leg. CONCLUSION: We could show that children have higher normal compartment pressures than adults in the lower leg. They seem to be able to tolerate higher absolute compartment pressures and lower pressure gradients before ACS occurs. More studies are needed to make a final statement on tolerable compartment pressures in children.

Prenatal and Postnatal Management of Gastroschisis in German-Speaking Countries: Is There a Standardized Management?

INTRODUCTION: Evidence-based guidelines or protocols regarding the perinatal management of babies born with gastroschisis are lacking. The aim of this work is to evaluate the different current treatment modalities for newborns with gastroschisis during the perinatal period in the German-speaking countries Germany, Austria, and Switzerland. These data could serve as a starting point for the development of a multicenter randomized controlled trial. MATERIALS AND METHODS: A questionnaire was developed with 30 questions divided into five sections: (1) prenatal diagnosis, (2) fetal therapy, (3) mode and timing of delivery, (4) operative management, and (5) postoperative management. All pediatric surgery institutions that treat newborns with gastroschisis were identified and asked to participate. Data were categorized by country and analyzed using descriptive statistics (frequency and percentage). RESULTS: The return rate of the questionnaire was 95% (89 hospitals). A standard procedure was identified regarding prenatal ultrasound monitoring, interdisciplinary team approach, planned delivery through cesarean section, postnatal coverage of the intestine with a silastic bag, first intervention within the first 6 hours after birth, attempt of primary abdominal wall closure, and perioperative antibiotic treatment. For many crucial parameters, management was not standardized. CONCLUSIONS: There is no gold standard in German-speaking countries on how to manage fetuses and babies with gastroschisis. Moreover, this report unveils some questionable elements of daily practice for which there is no evidence at all and which can jeopardize outcome and even prove fatal (fetal therapy, preterm delivery, lack of abdominal pressure monitoring). Prospective randomized-controlled multicenter studies are needed to set a standard.

Predictors of pediatric blunt cerebrovascular injury.

BACKGROUND/PURPOSE: Blunt cerebrovascular injury (BCVI) is clinically challenging because these injuries are hard to detect and can have serious neurological consequences, and optimal screening criteria have not been established for children. This study aims to determine risk factors for BCVI in pediatric patients and to evaluate screening practices in a single institutional series. METHODS: A retrospective review of all pediatric blunt trauma patients evaluated over a 10-year period was performed. Demographic, clinical, and radiographic data were reviewed, including the presence of adult risk factors for BCVI. Logistic regression analyses were performed with statistical significance established at p<0.05. RESULTS: Of the 11,596 patients evaluated during the study period, 1018 (8.8%) had at least one adult risk factor for BCVI, but only 62 (6.1% of those with risk factors) underwent angiographic evaluation. Overall, 11 BCVIs were observed, resulting in an incidence of 0.095%. All 11 patients with BCVI had at least one risk factor. Multivariate logistic regression analysis identified cervical spine fracture (OR 36.88 [8.36, 169.95]), GCS score ≤ 8 (OR 16.42 [2.16, 102.33]), male gender (OR 10.52 [1.33, 363.30]), Le Fort II or III facial fracture (OR 63.71 [2.16, 1124.68]), and ISS (unit OR 1.10 [1.04, 1.17]) as independent risk factors for BCVI. CONCLUSION: Adult screening criteria for BCVI appear appropriate for pediatric patients, but most at-risk children are not being screened. LEVEL OF EVIDENCE: Level III (retrospective case-control study).
