Consequently, guidelines for pediatric BOT management are minimal. We retrospectively examined the management of 15 adolescent patients who underwent BOT resection at our institution over 14 years, with a specific focus on recurrence. Data collected include age, symptoms, tumor characteristics, laboratory markers, surgical management, staging, and follow-up. Fifteen patients with BOTs (median age: 16 y) presented with abdominal pain (67%), or distention (33%). Cancer antigen-125 marker was elevated in 10/13 patients. There were 11 (73%) tumors with serous and 4 (23%) with mucinous histology. Most received fertility-preserving surgery (93%) and disease stage was 1A in 7 (47%), 1B/1C in 5 (33%), and stage 2B or higher in 3 (20%) patients. Additional staging procedures, including peritoneal washings (73%), omentectomy (53%), and peritoneal biopsy (47%), varied in use. Four (27%) patients recurred, with 1 case of benign tumor, 1 BOT, and 2 serous carcinomas. Median patient follow-up was 45 months. BOTs can be successfully treated with fertility-preserving surgery but demonstrate a non-negligible rate of recurrence. We recommend surgical staging and posttreatment surveillance for all patients with BOT.","PeriodicalId":16693,"journal":{"name":"Journal of Pediatric Hematology/Oncology","volume":" ","pages":""},"PeriodicalIF":0.9,"publicationDate":"2025-01-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142971386","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We report an atypical form of FNAIT with delayed onset in a healthy, breastfed male infant who developed diffuse petechiae 2 weeks after birth due to severe thrombocytopenia. The mother was shown to be negative for the human platelet antigen-1a (HPA-1a) allele but had anti-HPA-1a IgG antibodies, while the father and newborn were HPA-1a positive, confirming the diagnosis. Despite intravenous immunoglobulins and platelet transfusions, the recovery was slow. Analysis of breast milk demonstrated the presence of anti-HPA-1a IgG antibodies. The unusual clinical presentation 2 weeks after birth and the slow platelet recovery under appropriate treatment suggest postnatal transfer of maternal anti-HPA-1a antibodies or B lymphocytes producing these antibodies to the newborn, which may possibly have occurred through breastfeeding. Further research is needed to validate these findings and understand the role of breast milk in provoking the disease. Early detection and management remain essential to prevent serious complications associated with FNAIT.","PeriodicalId":16693,"journal":{"name":"Journal of Pediatric Hematology/Oncology","volume":" ","pages":""},"PeriodicalIF":0.9,"publicationDate":"2025-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142962294","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Forty-five participants reported SCD as a hereditary disease, and only 31 (37%) subjects reported that SCD could be prevented. Fourteen (70%) married patients reported that their children had been screened. Ninety-three (84%) children reported fatigue in the past 1 year. Seventy-four of them reported no absence from work/school in the past 1 year.

This brief procedure is frequently performed with sedation in young patients but with only local anesthesia in adults. Adolescent and young adult patients may be cared for by physicians with different training backgrounds and sedation preferences, making the utilization of sedation for lumbar punctures variable among providers. The benefits of sedation for young adults with leukemia undergoing lumbar puncture (analgesia, anxiolysis, safety) must be weighed against the obligate fasting interval, hospital cost, and resource allocation that is required.Methods: We conducted a survey of pediatric and medical oncologists who care for patients with acute lymphoblastic leukemia to assess their use of sedation for adolescents and young adults undergoing lumbar punctures as part of their cancer therapy. (see Supplemental Digital Content 1, http://links.lww.com/JPHO/A723).Results: Twenty-six percent of pediatric oncologists and 28% of medical oncologists completed the survey. Pediatric oncologists were more likely to perform lumbar punctures under sedation as compared with medical oncologists. This pattern remained consistent across all patient age ranges surveyed, despite no significant difference in the expected cumulative number of lumbar punctures that a patient was to undergo. Medical oncologists reported topicalization with local anesthetics before lumbar puncture more often than pediatric oncologists.Conclusion: Sedation practices for lumbar puncture during acute lymphoblastic leukemia treatment varies by specialty of treating oncologist.","PeriodicalId":16693,"journal":{"name":"Journal of Pediatric Hematology/Oncology","volume":" ","pages":""},"PeriodicalIF":0.9,"publicationDate":"2025-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142962222","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Between 1999 and 2018, a total of 123 patients diagnosed with B-ALL were initially identified, but after applying exclusion criteria, 105 patients were included in the evaluation, who were treated with COG protocols at our center. The mean follow-up duration for patients was determined to be a median of 74 months (min to max: 2 to 228 months).

Despite the complexity of this condition, there is no established standard therapy, and treatment options such as sclerotherapy, laser therapy, and surgery remain variably effective and are limited to symptom management rather than curative. Sirolimus, an mTOR pathway inhibitor, has shown promise as a primary therapy, particularly in patients without a driver mutation. However, in some instances, the genetic landscape of KLA has revealed somatic mutations in the RAS-MAPK pathway, most notably the NRAS variant (c.182A>G, p.Q61R), representing a potential therapeutic target. We present a case of a 4-year-old male who presented with pericardial and pleural effusions without notable coagulopathy found to harbor an NRAS p.Gln61Arg gene mutation, diagnosed through next-generation sequencing (NGS) analysis. Initial therapy with sirolimus failed to provide optimal benefit with persistent pleural effusion. Subsequent treatment with the MEK inhibitor trametinib led to significant clinical improvement, evidenced by the resolution of effusions and removal of the chest tube. In the short term, no significant adverse effect was reported. Our findings underscore the value of genomic profiling in guiding personalized treatment strategies for rare and complex diseases presenting like KLA. This case highlights the potential of targeted therapies, such as trametinib, in improving clinical outcomes for patients with disease with activating NRAS variants, emphasizing the importance of ongoing research to validate and expand these therapeutic approaches in the management of vascular anomalies.","PeriodicalId":16693,"journal":{"name":"Journal of Pediatric Hematology/Oncology","volume":" ","pages":""},"PeriodicalIF":0.9,"publicationDate":"2025-01-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142962299","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
