RESUMO
PURPOSE: YKT6 plays important roles in multiple intracellular vesicle trafficking events but has not been associated with Mendelian diseases. METHODS: We report 3 unrelated individuals with rare homozygous missense variants in YKT6 who exhibited neurological disease with or without a progressive infantile liver disease. We modeled the variants in Drosophila. We generated wild-type and variant genomic rescue constructs of the fly ortholog dYkt6 and compared their ability in rescuing the loss-of-function phenotypes in mutant flies. We also generated a dYkt6KozakGAL4 allele to assess the expression pattern of dYkt6. RESULTS: Two individuals are homozygous for YKT6 [NM_006555.3:c.554A>G p.(Tyr185Cys)] and exhibited normal prenatal course followed by failure to thrive, developmental delay, and progressive liver disease. Haplotype analysis identified a shared homozygous region flanking the variant, suggesting a common ancestry. The third individual is homozygous for YKT6 [NM_006555.3:c.191A>G p.(Tyr64Cys)] and exhibited neurodevelopmental disorders and optic atrophy. Fly dYkt6 is essential and is expressed in the fat body (analogous to liver) and central nervous system. Wild-type genomic rescue constructs can rescue the lethality and autophagic flux defects, whereas the variants are less efficient in rescuing the phenotypes. CONCLUSION: The YKT6 variants are partial loss-of-function alleles, and the p.(Tyr185Cys) is more severe than p.(Tyr64Cys).

Originally described as mammary analog secretory carcinoma (SC), SC of the salivary gland is a rare malignancy with morphologic and molecular similarities to SC of the breast. We present 2 children with salivary gland SC with the classic ETV6-NTRK3 gene fusion, including 1 with lymph node metastases. Both patients underwent surgical resection and were in remission 24 months postsurgery. One patient was additionally found to have synchronous papillary thyroid carcinoma with a TFG-MET fusion. A review of published cases highlights the expanding molecular profile and confirms the favorable course of salivary gland SC after surgical resection.

BACKGROUND: Pediatric papillary thyroid carcinoma (PTC) is clinically and biologically distinct from adult PTC. We sequenced a cohort of clinically annotated pediatric PTC cases enriched for high-risk tumors to identify genetic alterations of relevance for diagnosis and therapy. METHODS: Tumor DNA and RNA were extracted from FFPE tissue and subjected to next-generation sequencing (NGS) library preparation using a custom 124-gene hybridization capture panel and the 75-gene Archer Oncology Research Panel, respectively. NGS libraries were sequenced on an Illumina MiSeq. RESULTS: Thirty-six pediatric PTC cases were analyzed. Metastases were frequently observed to cervical lymph nodes (29/36, 81%), with pulmonary metastases less commonly found (10/36, 28%). Relapsed or refractory disease occurred in 18 patients (18/36, 50%). DNA sequencing revealed targetable mutations in 8 of 31 tumors tested (26%), most commonly BRAF p.V600E (n = 6). RNA sequencing identified targetable fusions in 13 of 25 tumors tested (52%): RET (n = 8), NTRK3 (n = 4), and BRAF. Mutually exclusive targetable alterations were discovered in 15 of the 20 tumors (75%) with both DNA and RNA analyzed. Fusion-positive PTC was associated with multifocal disease, higher tumor staging, and higher American Thyroid Association risk levels. Both BRAF V600E mutations and gene fusions were correlated with the presence of cervical metastases. CONCLUSIONS: Targetable alterations were identified in 75% of pediatric PTC cases with both DNA and RNA evaluated. Inclusion of RNA sequencing for detection of fusion genes is critical for evaluation of these tumors. Patients with fusion-positive tumors were more likely to have features of high-risk disease.

OBJECTIVE: Study of liver explants of biliary atresia (BA) patients with successful Kasai portoenterostomy (KP). METHODS: Pathology and medical records of BA liver explants from January 2009 to June 2018 with successful KP were reviewed along with appropriate controls. RESULTS: Fourteen out of 68 (20.6%) BA patients with LT had a successful KP. Median age at BA diagnosis, KP and LT was 60.5 days, 61 days, and 10 years, respectively, with conjugated bilirubin (c-bil) normalizing at 12.5 weeks after KP. Advanced fibrosis was diffuse in 2/14 (14.3%) explants, limited to periphery in 11/14 (78.6%) and absent in 1. Hilar partial nodular transformation (PNT) was seen in 11 explants (78.6%) and diffuse nodular regenerative hyperplasia (NRH) in 2 (14.3%). Areas of PNT and NRH showed diffuse portal sclerosis (100%), complete and incomplete portal vein (PV) stenosis (100%), PV herniation (100%), hypervascular portal tracts (20%), periportal abnormal vessels (100%), abundant lymphatic collaterals (100%), mild medial hepatic arterial hypertrophy (100%), and delicate fibrous septae (100%). Extrahepatic PVs showed variable luminal occlusion with mean PV intima to full thickness ratio of 0.6 +/- 0.11; significantly higher than age-matched noncirrhotic (nâ=â27, 0.08 +/- 0.09; Pâ<â0.0001) and cirrhotic controls (nâ=â19, 0.34 +/- 0.2; Pâ=â0.0015); and comparable to BA patients with failed KP (Pâ=â0.82) and without KP (Pâ=â0.04). CONCLUSIONS: BA patients with successful KP can present with obliterative portal venopathy (OPV). In the context of optimal bile drainage, portal hypertension may not be because of advanced parenchymal fibrosis but possibly because of OPV. Vascular abnormalities of the PV system should be investigated in BA patients.

Cystic fibrosis liver disease (CFLD) has long been postulated to be secondary to dysfunctional cystic fibrosis transmembrane conductance regulator in the apical biliary epithelium, leading to bile stasis and eventually cirrhosis with portal hypertension. However, pathologic changes in the cystic fibrosis (CF) liver are distinct from the pancreas and lungs in that fibrocystic changes are absent.1,2 Furthermore, the lack of clinically evident biliary obstruction and liver dysfunction suggest there may be alternative mechanisms that contribute to CFLD. Two recent studies in young adults described obliterative portal venopathy (OPV) and noncirrhotic portal hypertension (NCPH) as the predominant pathophysiology in young adults (median, 22 y) with CFLD.3,4 It is unknown if OPV develops early in childhood. Herein, we report the clinical features and liver pathology in 17 explants from children and adolescents with CF, representing 13.6% (17 of 125) of the CF liver transplant population in the United States according to the United Network for Organ Sharing and Organ Procurement and Transplantation Network.

Intratubular germ cell neoplasia (ITGCN) of the testis is a precursor to testicular germ cell tumor (TGCT), which can lead to the development of invasive cancer. In patients with a history of previously treated unilateral TGCT, treatment for ITGCN of the contralateral testis needs to be balanced with the risks of subsequent infertility. Here, we present a 17- year- old patient with ITGCN diagnosed after treatment of contralateral nonseminomatous TGCT who was successfully treated with a partial orchiectomy followed by low-dose radiation with preservation of his testosterone production.

One of the limitations of performing percutaneous biopsies in patients with bone sarcomas is the small amount of tumor that can be obtained for research purposes. Here, we describe our experience developing patient-derived tumor xenografts (PDXs) using percutaneous tumor biopsies in children with bone sarcomas. We generated 14 bone sarcoma PDXs from percutaneous tumor biopsies. We also developed eight bone sarcoma PDXs from surgical resection of primary bone tumors and pulmonary metastases. A multidisciplinary team approach was critical to establish an accurate diagnosis and to provide adequate tumor samples for PDX generation.

Angiomatoid fibrous histiocytoma (AFH) is a rare soft tissue tumor that has been associated with EWSR1-CREB1 gene fusion. Outcome in patients with unresectable distant metastases is generally fatal. Interleukin-6 (IL-6) secretion has been described in tumors with EWSR1-CREB1 fusion, and may promote tumor growth due to autocrine stimulation. Tocilizumab is an IL-6 receptor antibody that has potential benefit as a targeted therapy in refractory neoplasms with IL-6 secretion. We describe a child with metastatic AFH with EWSR1-CREB1 fusion and elevated IL-6 whose disease progressed during treatment with traditional chemotherapeutic agents, but improved after targeted therapy with tocilizumab.

PURPOSE AND OBJECTIVE: To determine the clinicopathologic and molecular features and outcome of children with mucoepidermoid carcinoma (MEC). METHODS: A retrospective analysis of clinical and histopathologic findings was performed in patients with MEC diagnosed at Texas Children's Cancer Center between 2000 and 2014. RESULTS: Ten female and four male patients with median age 12 years (range 7-19 years) were included in the study. Tumors involved major salivary glands, minor salivary glands of the palate, and the tracheobronchial tree. Nine of 11 patients with salivary MEC underwent more than one surgical resection at the time of initial diagnosis to achieve a gross total resection. Three patients with tracheobronchial tumors underwent pulmonary lobectomy. Three patients received postoperative radiation therapy. No patient was treated with chemotherapy. Histopathologic grades were classified as low (n = 2), intermediate (n = 9), and high (n = 3). All 12 patients with tumor tissue available for testing were positive for MECT1/MAML2 fusion transcripts. There were no deaths, metastases, or recurrences in this series, with a median follow-up of 24 months (range 5-96 months). CONCLUSIONS: Low to intermediate histopathologic grade MECs are more common than high grade MEC in children. In contrast to adults, MECT1/MAML2 fusion transcripts occur with a frequency of 100% in our pediatric MEC series. Complete excision is the treatment of choice and is associated with excellent outcome. The role of radiotherapy is unclear, but may be indicated in patients with high grade tumors with positive surgical margins.

BACKGROUND AIMS: Esophageal eosinophilia (EE) can be caused by gastroesophageal reflux disease (GERD), proton-pump inhibitor-responsive EE (PPI-REE) or eosinophilic esophagitis (EoE). This study quantified protein expression and S-nitrosylation (SNO) post-translational modifications in EE to elucidate potential disease biomarkers. METHODS: Proximal and distal esophageal (DE) biopsy proteins in patients with EE and in controls were assayed for protein content and fluorescence-labeled with and without ascorbate treatment. Protein SNO was determined, and selected protein spots were identified by matrix-assisted laser desorption ionization time-of-flight/mass spectrometry. Western blot and ingenuity pathway analysis were performed. RESULTS: Ninety-one of 648 proteins showed differential expression. There were significantly altered levels of abundance for 11 proximal and 14 DE proteins. Hierarchal clustering revealed differential SNO in inflamed tissues, indicating reactive nitrogen/oxygen species involvement. Galectin-3 was upregulated in both proximal (p < 0.04) and distal (p < 0.004) esophageal EE biopsies compared to controls. In distal EE samples, galectin-3 was significantly S-nitrosylated (p < 0.004). Principal component analysis revealed sample group discrimination distally. CONCLUSION: Proteomic analysis in EE esophageal mucosa revealed a distinct abundance and nitrosylation profile, most prominently in distal biopsies. Galectin-3 was upregulated in expression and SNO, which may indicate its potential role in mucosal inflammation. These results call for more studies to be performed to investigate the role of galectin-3 in GERD, PPI-REE and EoE.

Hematopoietic stem cell transplantation (HSCT) outcomes in X-linked severe combined immune deficiency are most effective when performed with patients <3 months of age and without coexisting morbidity, and with donor cells from a matched sibling. Even under such favorable circumstances, outcomes can be suboptimal, and full cellular engraftment may not be complete, which results in poor B or natural killer cell function. Protein losing enteropathies can accompany persistent immune deficiency disorders with resultant low serum globulins (immunoglobulin A [IgA], IgG, IgM) and lymphopenia. Patients with immune disorders acquire infections that can be predicted by their immune dysfunction. Fungal infections are typically noted in neutropenic (congenital or acquired) and T-cell deficient individuals. Coexisting fungal infections are rare, even in hosts who are immunocompromised, and they require careful evaluation. Antifungal treatment may result in drug-drug interactions with significant complications.

OBJECTIVES: The significance of antinuclear antibody (ANA) positivity in pediatric Hispanic patients with nonalcoholic fatty liver disease (NAFLD) is unknown. METHODS: ANA status was correlated with clinical, laboratory, and histologic parameters in Hispanic patients with a histologic diagnosis of NAFLD. RESULTS: Thirty-eight Hispanic children (27 male and 11 female) underwent liver biopsy at a median age of 12.1 years. Twenty patients (53%) had positive ANAs. The ANA-positive patients had higher fasting insulin levels (median [interquartile range (IQR)], 32.4 [25.4] µU/mL) and higher insulin resistance (median [Homeostatic Model Assessment for Insulin Resistance (HOMA-IR) IQR], 5.9 [3.1]) than the ANA-negative patients (fasting insulin: median [IQR], 17 [13.9] µU/mL and median [HOMA-IR IQR], 3.5 [2.6] µU/mL; P = .05 and .01, respectively). Serum high-density lipoprotein (HDL) cholesterol levels were higher in the ANA-negative patients (median [IQR], 47 [18] mg/dL) than the ANA-positive patients (38 [12] mg/dL) (P = .03). There were no statistical differences in a series of demographic, clinical, laboratory, and histologic parameters between the ANA-positive and the ANA-negative patients. At a median follow-up of 2.6 years, alanine aminotransferase was significantly lower than the baseline levels in both groups. In 1 patient undergoing ANA retesting, the titer had normalized from a baseline of 1:1,280 3.8 years earlier. CONCLUSIONS: In pediatric Hispanic patients with NAFLD, a positive ANA result is associated with insulin resistance and lower HDL cholesterol levels.

OBJECTIVE: The coronavirus disease 2019 (COVID-19) pandemic dramatically accelerated a growing trend toward online and asynchronous education and professional training, including in the disaster medicine and public health sector. This study analyzed the impact of the COVID-19 pandemic on the growth of the TRAIN Learning Network (TRAIN) for the year 2020 and evaluated pandemic-related changes in use patterns by disaster and public health professionals. METHODS: The TRAIN database was queried to determine the change in the number of registered users, total courses completed, and courses completed related to COVID-19 during 2020. RESULTS: In 2020, a total of 755,222 new users joined the platform - nearly 3 times the average added annually over the preceding 5 y (2015-2019). TRAIN users completed 3,259,074 training courses in 2020, more than double the average number of training courses that were completed annually from 2015-2019. In addition, 17.8% of all newly added disaster and public health training courses in 2020 were specifically related to COVID-19. CONCLUSION: Online education provided by TRAIN is a critical tool for just-in-time disaster health training following a disaster event or public health emergency, including in a global health crisis such as a pandemic.

ABSTRACT: A scoping review was conducted to describe the history of the National Disaster Medical System (NDMS) in the context of US military medical preparedness for a large-scale overseas military conflict. National Disaster Medical System civilian hospitals would serve as backups to military treatment facilities if both US Department of Defense and US Department of Veterans Affairs hospitals reached capacity during such a conflict. Systematic searches were used to identify published works discussing the NDMS in the scientific and gray literature. Results were limited to publicly available unclassified English language works from 1978 to January 2022; no other restrictions were placed on the types of published works. Full-text reviews were conducted on identified works (except student papers and dissertations) to determine the extent to which they addressed NDMS definitive care. Data charting was performed on a final set of papers to assess how these works addressed NDMS definitive care. The search identified 54 works published between 1984 and 2022. More than half of the publications were simple descriptions of the NDMS (n = 30 [56%]), and most were published in academic or professional journals (n = 38 [70%]). Only nine constituted original research. There were recurrent criticisms of and recommendations for improving the definitive care component of the NDMS. The lack of published literature on NDMS definitive care supports the assertion that the present-day NDMS may lack the capacity and military-civilian interoperability necessary to manage the casualties resulting from a large-scale overseas military conflict.

Spontaneous intestinal perforations in the neonatal population are mostly associated with low birth weight, prematurity, and necrotizing enterocolitis. Spontaneous intestinal perforation in the absence of these risk factors is extremely rare and should raise clinical concern for an underlying bowel pathology. Here we present a unique case of a normal-weight, full-term girl with spontaneous intestinal perforation due to a spindle cell neoplasm with a novel BRAF mutation and infantile fibrosarcoma-like morphology. Though rare, malignancy should be considered in the differential diagnosis for bowel perforation in an otherwise healthy, term infant as complete surgical excision can be curative.
RESUMO
BACKGROUND: Our purpose is to describe the structure, function and outcomes of our multidisciplinary pediatric thyroid program and to evaluate our experience in comparison to other high-volume centers. METHODS: We reviewed all thyroid operations performed 10/2012 through 09/2019, and examined number of cases per year, patient demographics, procedures, final diagnoses and results. Primary outcomes were hypoparathyroidism and recurrent laryngeal nerve (RLN) injury at 12 months. Data were analyzed using descriptive statistics and univariate analyses. RESULTS: We performed 294 thyroid operations on 279 patients. Seventy-nine percent were female. Median age was 15 years (IQR: 12-17). Operations included total thyroidectomy (65%), lobectomy (30%) and completion thyroidectomy (5%). Most common diagnoses were Graves' disease (35%), malignancy (29%), and benign nodule (20%). We developed an evidence-based clinical pathway and conducted weekly multidisciplinary meetings. A clinical data specialist reviewed process and outcome measures routinely. Overall, 6 patients (2.0%) had hypoparathyroidism and 2 (0.7%) had unilateral RLN injury at 12 months. Two of the patients with clinical suspicion of permanent hypoparathyroidism were ultimately weaned off calcium. Both patients with RLN injury had extensive locally advanced malignant disease involving the nerve. CONCLUSIONS: Our multidisciplinary team achieved excellent long-term outcomes for pediatric thyroid surgery comparable to other high-volume pediatric and adult centers.

Chronic cough is a common complaint in the pediatric population and can have many different etiologies. We present a rare case of a tracheal lobular capillary hemangioma (LCH), also known as pyogenic granuloma, causing chronic cough in a child. In this case, the tracheal LCH was managed successfully with laser ablation. A review of the literature reveals only 2 other reported pediatric cases of tracheal LCH. Laryngoscope, 131:1729-1731, 2021.
