Pediatric Appendicitis Transfers From Adult Centers: Can Alvarado Scores Help Determine Which Patients Need a CT?

BACKGROUND: Acute appendicitis is possible for any pediatric patient with abdominal pain. At our tertiary care center, patients are transferred for surgical management with unnecessary or excessive imaging. We hypothesize that using the Alvarado score (AS) to clinically stage patients will identify patient groups that could be transferred prior to imaging. METHODS: Retrospective review of pediatric patients transferred to our hospital for suspected appendicitis between 11/2020 and 3/2022 was performed. Variables collected included AS, imaging, and pathology. Alvarado score was calculated for each patient, and patients were grouped into low score, intermediate score, and high score groups. Positive predictive values (PPVs) were calculated for patients who underwent CT. RESULTS: 196 patients (age 2-17, 58% male) were transferred with suspected appendicitis. CT was obtained in 67% of patients and was not significantly different between groups. The low-score group (n=35) had a rate of appendicitis of 14% and the PPV of CT was 33%. The intermediate-score group (n = 74) had a rate of appendicitis of 62% and the PPV of CT was 88%. In the high-score group (n = 87), the rate of appendicitis was 92% and PPV of CT was 98%. DISCUSSION: Our data show that patients with low, intermediate, and high AS undergo CT at similar rates. We suggest that patients in the low score and high score groups may not benefit from reflexive CT given the likelihood of appendicitis based on the Alvarado score. We propose that CT in these groups be performed at the discretion of the pediatric center in order to expedite transfer and spare children excess radiation.

Reducing Phlebotomy, Length of Stay, Cost: Development of a Blunt Abdominal Trauma Pathway in a Level I, Pediatric Trauma Center.

OBJECTIVES: Blunt abdominal trauma (BAT) is a leading cause of morbidity in children with higher hemodynamic stabilities when compared with adults. Pediatric patients with BAT can often be managed without surgical interventions; however, laboratory testing is often recommended. Yet, laboratory testing can be costly, and current literature has not identified appropriate pathways or specific tests necessary to detect intra-abdominal injury after BAT. Therefore, the present study evaluated a proposed laboratory testing pathway to determine if it safely reduced draws of complete blood counts, coagulation studies, urinalysis, comprehensive metabolic panels, amylase and lipase levels orders, emergency department (ED) length of stay, and cost in pediatric BAT patients. METHODS: A retrospective review of levels I, II, and III BAT pediatric patients (n = 329) was performed from 2015 to 2018 at our level I, pediatric trauma center. Patients were then grouped based on pre-post pathway, and differences were calculated using univariate analyses. RESULTS: After implementation of the pathway, there was a significant decrease in the number of complete blood counts, coagulation studies, urinalysis, comprehensive metabolic panels, amylase, and lipase levels orders ( P < 0.05). Postpathway patients had lower average ED lengths of stay and testing costs compared with the pre pathway patients ( P < 0.05). There was no increase in rates of return to the ED within 30 days, missed injuries, or readmissions of patients to the ED. CONCLUSIONS: Results displayed that the adoption of a laboratory testing pathway for BAT patients reduced the number of laboratory tests, ED length of stay, and associated costs pediatric patients without impacting quality care.

Thoracoscopic intercostal to phrenic nerve transfer for diaphragmatic reanimation in a child with tetraplegia.

Context: To describe for the first time a novel technique of thoracoscopic intercostal nerve mobilization and intercostal to phrenic nerve transfer in the setting of tetraplegia with the goal of reanimating the diaphragm and decreasing ventilator dependence.Findings: A 5-year-old female on 24 h ventilator support secondary to traumatic tetraplegia was evaluated for possible phrenic nerve pacing. Left-sided phrenic nerve stimulation did not result in diaphragmatic contraction indicating a lower motor neuron injury. The patient underwent thoracoscopic mobilization of the left phrenic nerve and 10th intercostal nerve while positioned in the left lateral decubitus position using four 5 mm trocars. The mobilized intercostal nerve was transected close to its distal anterior termination and coapted without tension to the cut end of the terminal phrenic nerve using fibrin sealant. Lastly, phrenic nerve pacer leads and battery were implanted in the chest wall and connected to the electrode placed on the intercostal nerve. One year following the procedure, the patient was tolerating phrenic pacing during the day while requiring ventilation overnight. Currently, the patient is 2 years post-operative from this procedure and does not require ventilator support.Conclusion/clinical relevance: We have shown for the first time a novel approach of thoracoscopic nerve mobilization and phrenic to intercostal nerve transposition to be both safe and effective for restoring innervation of the diaphragm in a child. This minimally invasive procedure is recommended as the preferred approach to reanimate the diaphragm.

Admission of Pediatric Concussion Injury Patients: Is It Necessary?

BACKGROUND: Currently there is no consensus on the management of patients with a concussion and negative computed tomography (CT) of the head. This study examined the necessity of admitting pediatric patients with concussive symptoms. The purpose of this study was to determine if pediatric patients evaluated in the emergency department (ED) for concussion with a negative head CT scan require routine hospital admission. MATERIALS AND METHODS: A retrospective chart review of pediatric trauma patients admitted to the hospital for a concussion from 2010 to 2017 was conducted after IRB approval (1709005621). Only patients with a negative head CT were included. Demographic information, ED evaluation, and hospital course were reviewed. RESULTS: A total of 90 patients (Mage = 10 y; 72.2% male) were included in the analysis. The average Glasgow coma scale was 14.6 (range 9-15). Loss of consciousness was reported by 36.7% (n = 33) of patients. Reported symptoms included nausea/emesis in 35.5% (n = 32) and altered mental status in 40% (n = 36). Following admission, 94.4% of patients were discharged within 24 h of admission. Of the four patients (4.4%) that stayed longer than 24 h, only two hospitalizations were related to the concussion (inability to tolerate diet). One patient had a fever unrelated to the concussion and one stayed because of social issues. Average length of stay for these patients was 2.75 d (range 2-4 d). There was no difference in Glasgow coma scale in comparison to patients who were discharged within 24 h. CONCLUSIONS: Although there are a large number of pediatric patients evaluated in the ED for concussion injuries, very few of these patients require any further care. Our study suggests that patients with concussion and a negative head CT who tolerate a diet can be safely discharged home.

Single-lateral cervical radiograph in pediatric trauma is equivalent to multiple views.

BACKGROUND: Cervical spine injuries (CSI) are rare within the pediatric population. Due to the significant consequences of missed CSI, children are often imaged excessively. In an attempt to decrease imaging of the cervical spine in children, we reviewed abnormal cervical radiographs (XR) to determine if the diagnosis of CSI could be made using a single-lateral cervical radiograph (LAT). Furthermore, we reviewed cervical computed tomography (CT) and magnetic resonance imaging (MRI) to ensure there were no missed CSI. METHODS: Electronic medical records of trauma patients treated at a Level I Pediatric Trauma Center with abnormal XR findings followed by confirmatory CT or MRI between 2012 and 2017 were reviewed. All abnormal imaging on XR was compared with the LAT. In addition, all abnormal CTs and MRIs were reviewed to ensure there were no false negative XR. RESULTS: A total of 3,735 XR were performed with 26 abnormal interpretations. All bony CSI were visualized on LAT. Confirmatory imaging found 13 (50%) were false positive and 13 (50%) were true positive. Secondary analysis of CT identified 12 injuries with prior XR; 8 of 12 LAT identifying the injury and 4 of 12 false positive on CT. Secondary analysis of MRI identified nine injuries with prior XR; 5 of 9 LAT identifying the injury. The four false-negative reads on MRI were ligamentous injuries. CONCLUSION: Radiographs are commonly performed when evaluating CSI. In our population, initial assessment with a single LAT was equivalent to a multiple view XR. On secondary review, the only false-negative LAT reports were due to ligamentous injuries. This data suggests limiting exposure to LAT would accomplish the goal of reducing imaging without missing bony CSI and when ligamentous injury is suspected MRI should be the confirmatory study rather than CT. LEVEL OF EVIDENCE: Diagnostic Test, level III.

Standardization of common bile duct size using ultrasound in pediatric patients.

BACKGROUND/PURPOSE: The incidence of choledocholithiasis is increasing. The diagnosis of common bile duct (CBD) obstruction is based on abnormal CBD size. Establishing norms for CBD size in children would improve diagnostic accuracy. We analyzed ultrasounds (US) to determine normal pediatric CBD size based on age and then validated this against patients with choledocholithiasis. METHODS: A retrospective review was conducted for children less than 21 years of age with US defined CBD size. Patients were stratified into age groups by ANOVA statistical analysis. Secondary analysis included patients with confirmed choledocholithiasis in comparison to the normal cohort. RESULTS: A total of 778 patients had US without pathology. Group 1 (<1 year) had a mean CBD of 1.24±0.54 mm, group 2 (1-10 years) 1.97±0.71 mm, and group 3 (>10 years) 2.98±1.17 mm, p<0.05. Fourteen additional patients were found to have choledocholithiasis with a mean CBD size of 8.1 mm. All patients with choledocholithiasis had CBD sizes outside of our normal range, but only 50% of patients had enlarged CBD size based on adult normal range of values. CONCLUSION: Normal CBD size in children is less than a normal adult patient. More accurate normal values will aid in determining if a child needs further evaluation for possible obstruction of the CBD. TYPE OF STUDY: diagnostic Level of evidence: III.

Racial and ethnic disparities in treatment and survival of pediatric sarcoma.

BACKGROUND: Childhood sarcomas are rare and require complex interdisciplinary care including surgery, chemotherapy, and radiation. The goal of this study was to determine if racial or ethnic disparities exist for pediatric sarcoma patients in the United States. METHODS: The United States' National Cancer Institute's Surveillance, Epidemiology, and End Results database was used to identify patients aged 0-21 diagnosed with primary sarcomas from 1973 to 2012. Patients were considered by race and ethnicity. Survival curves were computed using the Kaplan-Meier method and the log-rank test. RESULTS: A total of 11,502 patients were included in this study. When stratified by race, non-Hispanic black and Hispanic patients were significantly more likely to present with advanced stage disease than white patients. White patients were more likely to receive radiation therapy than black and Hispanic patients (P = 0.01). There was no significant difference between patients who underwent surgery (P = 0.21). Overall survival was better for white patients than black or Hispanic ones. Despite the overall 5-year survival improvement during the study period (56.2%-70.3%), survival disparities between race and ethnicity have grown. CONCLUSIONS: Racial and ethnic disparities do exist with respect to stage, treatment, and survival of these rare tumors. Black and Hispanic patients are presenting at more advanced stage and have overall worse survival. This survival disparity has widened over the past 4 decades.

Pancreaticoduodenectomy for pediatric and adolescent pancreatic malignancy: A single-center retrospective analysis.

PURPOSE: While pancreaticoduodenectomy (PD) has been extensively studied in adults, there are few data pertaining specifically to pediatric patients. We retrospectively analyzed PD-associated morbidity and mortality in pediatric patients. METHODS: Our analytic cohort included all consecutive patients ≤18years of age treated at our institution from 1993 to 2015 who underwent PD. Patient data (demographics, disease characteristics, surgical and adjuvant treatment, length of hospital stay, and postoperative course) were extracted from the medical records. RESULTS: We identified 12 children with a median age of 9years (7 female, 5 male). Final diagnoses were pancreatoblastoma (n=3), solid pseudopapillary tumor (n=3), neuroblastoma (n=2), rhabdomyosarcoma (n=2), and neuroendocrine carcinoma (n=2). Four patients underwent PD for resection of recurrent disease. 75% (9/12 patients) received neoadjuvant therapy. The median operative time was approximately 7hours with a mean blood loss of 590cm3. The distal pancreas was invaginated into the posterior stomach (n=3) or into the jejunum (n=5) or was directly sewn to the jejunal mucosa (n=4). There were no operative deaths. There were 4 patients (34%) with grade II complications, 1 with a grade IIIb complication (chest tube), and 1 with a grade IV complication (reexploration). The most common long-term morbidity was pancreas exocrine supplementation (n=10; 83%). Five patients (42%) diagnosed with either solid pseudopapillary tumor or rhabdomyosarcoma are currently alive with a mean survival of 77.4months. CONCLUSION: Pancreaticoduodenectomy is a feasible management strategy for pediatric pancreatic malignancies and is associated with acceptable morbidity and overall survival. Long-term outcome is mostly dependent on histology of the tumor. LEVEL OF EVIDENCE: Level IV; retrospective study with no comparison group.

The incidence of over-the-counter medication use in patients with midgut neuroendocrine tumors.

Recent increases in the use of over-the-counter (OTC) medicines and the underreporting of the use of these medications to physicians have sparked interest in the number and types of "supportive" therapies used by patients with neuroendocrine tumors (NETS). Patients with NETS are of special interest as a result of the potential interactions/interferences between tumor-associated peptide and amine production and OTC supplements. A prospective analysis of patients with primary small bowel NETS between 1998 and 2012 was conducted to define and catalog each patient's prescription and OTC medication use at each clinic visit. The most recently recorded patient medications were used for this analysis. Three hundred sixty-two patients with small bowel primary NETS were studied. One hundred eighty-seven patients (51.6%) were taking nutritional supplements. Of these taking supplements, the per cent of patients taking one, two, three, or more than three supplements was 28.3, 24.1, 22.5, and 25.1 per cent, respectively. Females (n = 109) were more likely to take supplements in comparison to males (n = 78; P = 0.037). Fifty one patients (14.1%) took proton pump inhibitors and 31 patients (8.6%) took loperamide. OTC supplements were used by 50 per cent of patients with primary small bowel NETS in this study. Over one-third of our patients reported using three or more OTC medicines daily. These medicines have the potential to interact with the metabolism of prescribed medicines, modify ability to clot during surgery, exacerbate NET symptoms, and alter NET markers. Given the prevalence of OTC medications and their potential actions, it is important to carefully catalog their use.

Hyperkinetic gallbladder: an indication for cholecystectomy?

Cholecystectomy may benefit children with biliary colic without stones on ultrasound (US) or low ejection fraction on cholecystokinin-hepatobiliary iminodiacetic acid (CCK-HIDA) scan. Children with symptomatic biliary colic and abnormal HIDA scan, specifically those with high ejection fractions, may benefit from cholecystectomy. All patients younger than 18 years old undergoing cholecystectomy from 2008 to 2012 in our practice were reviewed. Patients with a negative US and CCK-HIDA ejection fractions 80 per cent or greater were included in the study. Patient data were extracted from charts, whereas postoperative symptoms were obtained by phone interviews. Of 174 patients who underwent cholecystectomy, 12 (7%) met study criteria. All patients (12 of 12) had evidence of cholecystitis on the final pathology note. All 11 patients contacted had relief of colic after gallbladder removal with a mean follow-up of 16 months. A subset of pediatric patients with high ejection fractions on CCK-HIDA and symptomatic biliary colic may have symptomatic relief with cholecystectomy.

Congenital esophageal diverticulum - a case report and review of literature.

Zenker's Diverticulum (ZD) is a false diverticulum located in the posterior esophagus between the cricopharyngeus and inferior constrictor. Few cases have been reported in the pediatric population. Congenital esophageal diverticulum is commonly associated with additional esophageal anatomical deformities or iatrogenic injury in the early post-natal period. TD was born at 39 5/7 weeks gestational age and did well at home with the exception of "choking during feeds 2-4 times per day" with mild cyanosis. Flexible bronchoscopy performed under sedation revealed a retropharyngeal mass protruding towards the epiglottis resulting in upper airway obstruction. Esophogram demonstrated upper esophageal diverticulum. Patient underwent left neck dissection with cervical myotomy from the cricopharyngeus to the level of the thoracic inlet. A postoperative repeat esophogram illustrated resolution of the diverticulum. Currently, the patient is 9 months postoperative and is tolerating feeds by mouth, gaining weight and has no pulmonary symptoms. There have been a few reports of ZD in children occurring in combination with anatomical abnormalities or esophageal manipulation. This case is one of the youngest reported and occurs in a patient without any previous manipulation of the esophagus. This condition is exceedingly rare but should be included in the differential diagnosis for both pharyngoesophageal and tracheal symptoms.

Do primary neuroendocrine tumors and metastasis have the same characteristics?

BACKGROUND: Only one tumor site is usually biopsied to determine the histologic features of that patient's entire tumor burden. We hypothesized that there are significant histologic and functional differences in primary neuroendocrine tumors (NETS) and their nodal or organ metastases. We also hypothesized that limited tumor sampling could lead to erroneous assumptions about the tumor's histologic characteristics and clinical behavior. MATERIALS AND METHODS: Thirteen patients with metastatic well differentiated midgut NETS underwent simultaneous removal of their primary tumor, nodal metastasis, and organ metastasis. Each tumor site was stained quantitatively for Ki-67, chromogranin A (CGA), synaptophysin, CD31, and Factor VIII. Samples were also evaluated with in vitro tumor angiogenesis and drug chemoresistance assays. RESULTS: Ki-67 staining was nearly identical at all sites tested. Quantitative stains for CGA, synaptophysin, cluster of differentiation 31 (CD31), and Factor VIII varied considerably among the patient's three tissue site samples. Only 6% of the tissue samples tested against a battery of chemotherapeutic agents exhibited susceptibility to a single drug at all three tumor sites. In contrast, several antiangiogenic agents exhibited uniform effectiveness across all three tissue sites in multiple patients. CONCLUSIONS: Sampling only one NET tumor site may lead to erroneous assumptions about the tumor's histologic features and functional behavior. Evaluation of primary tumors and their nodal and organ metastasis may be necessary to optimize clinical decision making.
