Histopathologic Diagnosis

Meningioangiomatosis (MA) is a rare intracranial hamartomatous lesion. We retrospectively reviewed the MRIs in 6 pediatric patients with a histopathologic diagnosis of MA. Patients with MA demonstrated a solitary lesion in the frontotemporal regions, with FLAIR hyperintensity and leptomeningeal enhancement. A solitary brain lesion in the frontotemporal lobes associated with leptomeningeal enhancement and T2/FLAIR hyperintensity should include the possibility of MA in a pediatric patient who presents with seizures or headaches.

Relative Prevalence

ABSTRACTVery little is known about the prevalence and composition of various types of extended-spectrum β-lactamases (ESBL) in pediatric patients. The aims of this study were the following: (i) to determine the prevalence of ESBLs amongEnterobacteriaceaein a tertiary-care pediatric population; (ii) to characterize the genetic composition of the identified ESBL enzymes; and (iii) to determine the relative prevalence of CTX-M enzymes andEscherichia coliST131 strains among ESBL-producing isolates in the same pediatric patient population. Among the 1,430Enterobacteriaceaeisolates screened for elevated MICs to cefotaxime and/or ceftazidime from pediatric patients during a 1-year period, 94 isolates possessed at least one ESBL gene. CTX-M was the most commonly isolated ESBL type, consisting of 74% of all ESBLs versus 27% TEM and 24% SHV enzymes. Sequence analysis and probe-specific real-time PCR revealed that the majority (80%) of the CTX-M-type ESBLs were CTX-M-15 enzymes, followed by CTX-M-14 (17%) and CTX-M-27(2.8%). Multilocus sequence typing (MLST) and repetitive PCR analyses revealed that the relative prevalence of ST131 among ESBL-producingE. coliisolates is 10.2%. This study highlights the growing problem of ESBL resistance in pediatricEnterobacteriaceaeisolates and demonstrates a transition toward the predominance of CTX-M-type enzymes among ESBL-producingEnterobacteriaceaeorganisms causing pediatric infections.

Head and neck tumors are rare in pediatric patients but should be kept in the differential when a patient presents with a new swelling or mass. One of these tumors is a myxoma, which is an insidiously growing, benign mass originating from the mesenchyme. They most commonly arise in the myocardium but can also develop in facial structures, particularly in the maxilla and mandible. When arising in facial structures, ocular, respiratory, and digestive systems can be affected based on local invasion. Complete surgical resection is curative but can lead to significant morbidity as well. Here, we present a case of a 15-month-old toddler presenting with a paranasal mass, which was ultimately diagnosed as a maxillary myxoma. This tumor is very rare in the pediatric population, especially in the toddler age-group, reminding clinicians to broaden the differential diagnosis when a patient’s course is atypical.

Abstract Background To meet the core elements required for antimicrobial stewardship programs, our institution implemented a pharmacy-led antibiotic timeout (ATO) process in 2017 and a multidisciplinary ATO process in 2019. An antibiotic timeout is a discussion and review of the need for ongoing empirical antibiotics 2-4 days after initiation. This study sought to evaluate both the multidisciplinary ATO and the pharmacy-led ATO in a pediatric population, compare the impact of each intervention on antibiotic days of therapy (DOT) to a pre-intervention group without an ATO, and to then compare the impact of the pharmacy-led ATO versus multidisciplinary ATO on antibiotic days of therapy (DOT). Methods This was a retrospective, pre-post, quasi-experimental study of pediatric patients comparing antibiotic DOT prior to ATO implementation (pre-ATO), during the pharmacy-led ATO (pharm-ATO), and during the multidisciplinary ATO (multi-ATO). The pre-ATO group was a patient sample from February-September 2016, prior to the initiation of a formal ATO. The pharmacy-led ATO was implemented from February-September 2018. This was followed by a multidisciplinary ATO led by pediatric residents and nurses from February-September 2019. Both the pharm-ATO and the multi-ATO were implemented as an active non-interruptive alert added to the electronic health record patient list. This alert triggered when new antibiotics had been administered to the patient for 48 hours, at which time, the responsible clinician would discuss the antibiotic and document their decision via the alert workspace. Pediatric patients receiving IV or PO antibiotics administered for at least 48 hours were included. The primary outcome was DOT. Secondary outcomes included length of stay (LOS) and mortality. Results 1284 unique antibiotic orders (n= 572 patients) were reviewed in the pre-ATO group, 868 (n= 323 patients) in the pharm-ATO and 949 (n= 305 patients) in the multi-ATO groups. Average DOT was not significantly different pre vs post intervention for either methodology (Table 1). Mortality was similar between groups, but LOS was longer for both intervention groups (Table 1). Impact of an ATO on DOT, Mortality and LOS Conclusion An ATO had no impact on average antibiotic DOT in a pediatric population, regardless of the ATO methodology.

Background.The prevalence of obstructive sleep apnea (OSA) in the pediatric population is currently estimated at 1-2% of all children. The purpose of this study was to investigate the clinical and hemodynamic characteristics in pediatric patients with cor pulmonale and OSA.Methods.Thirty children with the diagnosis of OSA were included. These patients consisted of 26 male and 4 female children with a mean age of 7 ± 4 years old. Five of those children were found to be associated with cor pulmonale, and 25 had OSA but without cor pulmonale.Results.The arousal index was much higher in children with OSA and cor pulmonale. The children with OSA and cor pulmonale had much lower mean and minimal oxygen saturation and a higher incidence of bradycardia events. All 5 patients with OSA and cor pulmonale underwent an adenotonsillectomy, and the pulmonary arterial pressure dropped significantly after the surgery.Conclusion.This study demonstrated that the OSA pediatric patients with cor pulmonale had the different clinical manifestations and hemodynamic characteristics from those without cor pulmonale. The adenotonsillectomy had excellent results in both the OSA pediatric patients with and without cor pulmonale.

Abstract BACKGROUND Numerous variant BRAF genetic alterations have been associated with malignancies. BRAF activating fusions/mutations are frequently present in low grade gliomas. BRAF intragenic deletions have been reported in melanoma, but have not previously been reported in gliomas. OBJECTIVE To report a BRAF intragenic deletion in a pediatric patient with recurrent low-grade glioma. RESULTS A 3-year-old female underwent a complete resection of a posterior fossa pilocytic astrocytoma. She had recurrences at age 4, and then at age 9; pathology was consistent with pilocytic astrocytoma. Microarray analysis on sample from the first recurrence showed one region of loss encompassing 86 Kbp within the BRAF gene. The deletion breakpoints are within intron 1 and 9, resulting in loss of exons 2 through 9, inclusive. This has been previously described melanoma, but appears to be a novel finding in glioma. It is hypothesized that, since the loss retains the kinase and ATP binding pocket domains but deletes the N-terminal conserved region 1 and 2 (CR1, CR2) of the BRAF gene, it is likely functionally similar to the loss and activation resulting from the more usually described KIAA1549 and BRAF gene fusion. CONCLUSION This is the first BRAF intragenic deletion involving exons 2–9 reported in a glioma. Although 86kbp is small using whole genome microarray technology, it is large using sequencing strategies, and a targeted sequencing approach to investigate the BRAF gene would not readily identify this deletion. It is speculated that the deletion may be under ascertained in the pediatric population.

Abstract Background Midregional-proadrenomedullin (MR-proADM) is a useful prognostic peptide in severe infectious pathologies in the adult population. However, there are no studies that analyze its utility in febrile urinary tract infection (fUTI) in children. An accurate biomarker would provide an early detection of patients with kidney damage, avoiding other invasive tests like renal scintigraphy scans. Our objective is to study the usefulness of MR-proADM as a biomarker of acute and chronic renal parenchymal damage in fUTI within the pediatric population. Methods A prospective cohort study was conducted in pediatric patients with fUTI between January 2015 and December 2018. Plasma and urine MR-proADM levels were measured at admission in addition to other laboratory parameters. After confirmation of fUTI, renal scintigraphy scans were performed during the acute and follow-up stages. A descriptive study has been carried out and sensitivity, specificity and ROC curves for MR-proADM, C-reactive protein, and procalcitonin were calculated. Results 62 pediatric patients (34 female) were enrolled. Scintigraphy showed acute pyelonephritis in 35 patients (56.5%). Of those patients, the median of plasmatic MR-proADM (P-MR-proADM) showed no differences compared to patients without pyelonephritis. 7 patients (11.3%) developed renal scars (RS). Their median P-MR-proADM levels were 1.07 nmol/L (IQR 0.66–1.59), while in patients without RS were 0.48 nmol/L (0.43–0.63) (p < 0.01). The AUC in this case was 0.92 (95% CI 0.77–0.99). We established an optimal cut-off point at 0.66 nmol/L with sensitivity 83.3% and specificity 81.8%. Conclusion MR-ProADM has demonstrated a poor ability to diagnose pyelonephritis in pediatric patients with fUTI. However, P-MR-proADM proved to be a very reliable biomarker for RS prediction.

Introduction: New daily persistent headache (NDPH) is a primary headache disorder characterized by an intractable, daily, and unremitting headache lasting for at least 3 months. Currently, there are limited studies in the pediatric population describing the characteristics of NDPH. Objective: The objective of the current study is to describe the characteristics of NDPH in pediatric patients presenting to a headache program at a tertiary referral center. Methods: The participants in the current study were pediatric patients who attended the Headache Clinic at Children’s National Hospital between 2016 and 2018. All patients seen in the Headache Clinic were enrolled in an institutional review board–approved patient registry. Results: Between 2016 and 2018, NDPH was diagnosed in 245 patients, representing 14% of the total headache population. NDPH patients were predominantly female (78%) and white (72%). The median age was 14.8 years. The median pain intensity was 6 of 10 (standard deviation = 1.52). Most patients reported experiencing migrainous features, namely, photophobia (85%), phonophobia (85%), and a reduced activity level (88%). Overall, 33% of patients had failed at least 1 preventive medication, and 56% had failed at least 1 abortive medication. Furthermore, 36% of patients were additionally diagnosed with medication overuse headache. Conclusion: NDPH is a relatively frequent disorder among pediatric chronic headache patients. The vast majority of these patients experience migrainous headache characteristics and associated symptoms and are highly refractory to treatment—as evidenced by a strong predisposition to medication overuse headache and high rates of failed preventive management.

Background: Retrospective cohort study evaluating long term keratoconus progression amongst cross-linking (CXL) treated pediatric patients in the treated and the fellow untreated eyes. Methods: Data on 60 eyes of 30 patients, 18 years old or younger, who underwent CXL in at least one eye was collected and analyzed. Follow-up measurements taken from the treated and untreated eye up to 7 years after CXL treatment, were compared to baseline measurements. Parameters included uncorrected distance visual acuity (UCDVA), best-corrected spectacle visual acuity (BCSVA), manifest refraction, pachymetry, corneal tomography, and topography. Results: Mean age of patients was 16 ± 2.1 years. For the treated eyes, during follow-up period mean UCDVA had improved (from 0.78 ± 0.22 at baseline to 0.58 ± 0.26 logMAR at 7 years; p = 0.13), as well as mean BCSVA (from 0.23 ± 0.107 at baseline to 0.172 ± 0.05 logMAR at 7 years; p = 0.37). The mean average keratometry showed a significant flattening (from 49.95 ± 4.04 to 47.94 ± 3.3 diopters (D); p < 0.001), However there was no change in the mean maximal keratometry. The mean minimal corneal thickness (MCT) showed a significant mild reduction of 26 µm ( p = 0.006). Although statistically insignificant, the mean manifest cylinder was also reduced to 2D ( p = 0.15). During the follow-up period, eight untreated eyes (26.6%) deteriorated and underwent CXL, while only one treated eye (3.33%) required an additional CXL. Conclusion: CXL is a safe and efficient procedure in halting keratoconus progression in the pediatric population, the fellow eye needs to be carefully monitored but only a 25% of the patients will require CXL in that eye during a period of 7 years.

Abstract Objective Antimicrobial resistance poses a serious threat to children's health. In recent years, high-risk Escherichia coli ST131 has become an important target for global surveillance studies. The E.coli ST131 clone is associated with extended spectrum β-lactamase (ESBL) production, as well as multidrug resistance and treatment failure. Studies on this clone in the pediatric age group are limited. We aim to investigate the rate of high-risk E. coli ST131 clone in ESBL-positive E. coli isolates obtained from pediatric patients. Methods A total of 292 ESBL-positive E. coli isolates from clinical samples of pediatric patients was included in the study. MALDI-TOF MS system was used for bacterial identification. Susceptibility tests were performed using BD Phoenix automated system. ST131 detection was done by MALDI-TOF-MS. Fisher's exact test was used to compare the groups (significance <0.05). Results A total of 292 isolates was analyzed. The high-risk ST131 clone was detected in 117 (40%) of the 292 ESBL-positive isolates. ST131 rates were found to be significantly higher in children under the age of 5 years compared with children over the age of 5 years (49.3 vs. 31.1%, p = 0.0019). Ciprofloxacin resistance was higher in ST131 isolates (45.6 vs. 31.7%; p < 0.05). Conclusion The rate of the ST131 clone was found to be high in the pediatric population. The significantly high rate of resistance to ciprofloxacin, which is not commonly used in the pediatric population, in ST131 isolates reveals the importance of the spread of high-risk clones for the development of resistance.

Parathyroid Adenomas

AbstractBackground:Hyperparathyroidism (HPT) is a rare disease in the pediatric population, and optimal management may be unclear if it is due to an occult parathyroid adenoma. We present a case report of a pediatric patient with an occult, ectopic, supernumerary, parathyroid adenoma.Case presentation:A 13-year-old female who initially presented with anxiety was diagnosed with HPT. Preoperative imaging and bilateral neck exploration with four-gland biopsy were negative for any parathyroid adenoma. Postoperative MRI identified a thymic mass. She subsequently underwent video-assisted thoracoscopic thymectomy with resection of an intrathymic parathyroid adenoma.Conclusions:The diagnosis of pediatric HPT is increasing. Supernumerary or occult parathyroid adenomas are rare and add complexity to presurgical planning and management. Our case represents the rare occurrence of a pediatric ectopic supernumerary occult parathyroid adenoma treated with a two-stage approach utilizing multiple imaging studies. We provide a review of the pathology and propose an algorithmic approach to manage these complex patients.
