Pericardial Effusion Causing Cardiac Tamponade in a 10-Year-Old Male.

A 10-year-old male with a past medical history of premature pubarche, mild persistent asthma, and eczema presented to the emergency department with progressive dyspnea and chest pain. On examination, he was found to be tachycardic and tachypneic. Chest radiograph demonstrated cardiomegaly, bilateral pleural effusions, and scattered atelectasis. Echocardiogram revealed a large pericardial effusion with right atrial collapse. The patient was admitted to the pediatric ICU for pericardiocentesis and drain placement. As he later became hypertensive and febrile, we will discuss how our patient's hospital course guided our differential diagnosis and how we arrived at a definitive diagnosis using a multidisciplinary approach.

The Risk of Tumor Contamination Associated With Thoracic Instrumentation in Patients With Osteosarcoma: 2 Case Reports and a Literature Review.

Orthopedic surgeons are well aware of tumor contamination at the site of initial biopsy in osteosarcoma. However, tumor contamination in patients with osteosarcoma associated with thoracic instrumentation is not well described. The authors summarize 2 reported cases in addition to the 2 cases at their institution of this phenomenon. Knowledge of tumor contamination and preventative measures against tumor contamination is sparse in the literature, especially pertaining to patients with osteosarcoma undergoing thoracic instrumentation. In this report, the authors hope to increase awareness of these cases and suggest preventative measures to mitigate against tumor contamination in patients with osteosarcoma. The authors report that the median time between thoracic instrumentation and the visible detection of tumor migration to local sites was 5 months. They conclude that tumor contamination associated with thoracic instrumentation is characterized by patients with multiple sites of relapse and aggressive, fatal disease.

Evaluation of a gender-affirming healthcare curriculum for second-year medical students.

BACKGROUND: Transgender medicine is an emergent subfield with clearly identified educational gaps. AIMS: This manuscript evaluates a gender-affirming healthcare curriculum for second-year medical (M2) students. METHODS: Students received a survey assessing Gender Identity Competency in terms of skills, knowledge and attitudes regarding transgender and gender non-conforming (TGNC) issues. The authors administered the survey before and after the delivery of the curriculum. The curriculum included five online modules, a quiz, a 3-hour case-based workshop and a 2-hour interactive patient-provider panel. RESULTS: Approximately 60% of M2 students (n=77) completed both preassessments and postassessments. The following showed a statistically significant improvement from preassessment to postassessment: student Gender Identity Competency, t(76) = -11.07, p<0.001; skills, t(76) = -15.22, p<0.001; and self-reported knowledge, t(76) = -4.36, p<0.001. Negative attitudes did not differ (p=0.378). Interest in TGNC issues beyond healthcare settings did not change (p=0.334). M2 students reported a significant change in experience role-playing chosen pronouns in a clinical setting, t(76) = -8.95, p<0.001. CONCLUSIONS: The curriculum improved students' gender-affirming medical competency, knowledge and skills. The development of a sustained, longitudinal curriculum is recommended in addition to the continuing education of faculty to reinforce this expanding knowledge and skills base and to address discomfort working with this population.

Radiation Exposure in Pediatric Sarcoma Patients Receiving Initial Curative Chemotherapy.

The objective of our study is to estimate the radiation exposure to pediatric patients with sarcoma getting required (or highly recommended) ionizing radiation scans during initial chemotherapy and to determine how often distant progressive disease was discovered. Data from the last 25 years from the Children's Oncology Group open phase III protocols were reviewed for the most common pediatric sarcomas: osteosarcoma, Ewing's sarcoma, and rhabdomyosarcoma. The number of required/recommended ionizing radiation scans, including chest radiographs, chest computed tomography, positron emission tomography scans, and bone scans during induction, consolidation, and maintenance chemotherapy, were recorded and the total radiation dose per patient was calculated. In addition, the number of patients who were removed from protocol during chemotherapy because of new or distant progressive disease was documented. In our analysis of 5845 patients, the average pediatric patient with sarcoma on protocol was exposed to an ionizing radiation dose of 37.1 mGy, equivalent to the lifetime dose of nuclear power plant workers, whereas the progression of disease was detected at most in 5.4% of the patients. Our study is meant to inform pediatric oncologists more precisely of the actual risks and benefits of mandated surveillance scans during chemotherapy in patients with sarcoma.

Young Adult With Osteosarcoma of the Mandible and the Challenge in Management: Review of the Pediatric and Adult Literatures.

Neoadjuvant chemotherapy for osteosarcoma of the jaw (OSJ) remains controversial despite being a standardized treatment in osteosarcoma of the long bones. We present a case of a 22-year-old male with OSJ and performed a retrospective systemic review of previously published literatures of OSJ. We identified 27 articles: 7% recommended neoadjuvant chemotherapy, 22% recommended adjuvant chemotherapy, 19% recommended both neoadjuvant and adjuvant chemotherapy, 33% recommended against chemotherapy and 19% stated the role of chemotherapy is unknown. The lack of consensus regarding the use of chemotherapy in OSJ, despite its benefits, demonstrates the need to establish a standardized algorithm for OSJ.

Docetaxel, bevacizumab, and gemcitabine for very high risk sarcomas in adolescents and young adults: A single-center experience.

BACKGROUND: Adolescent and young adult (AYA) patients with very high risk sarcomas have poor outcomes and are in need of novel therapies. PROCEDURE: From January 2005 to February 2016, we retrospectively identified all AYA patients with relapsed or metastatic high-grade sarcomas, who were treated with at least one cycle of docetaxel (T), bevacizumab (A), and gemcitabine (G) (TAG ; T = 100 mg/m2 Day 8, A = 15 mg/kg Day 1, G = 1,000 mg/m2 Days 1 and 8). RESULTS: Fourteen patients, median age of 20 (15-30), received a total of 80 cycles of TAG, and were followed for a median of 83 months. Diagnosis included osteosarcoma (OST; 8), Ewing sarcoma (3), and soft tissue sarcoma (3). Five of 14 patients achieved clinical remission (CR), 3 had partial responses (PR), 3 had stable disease (SD), and 3 had progressive disease (PD). The median progression-free survival and overall survival were 7 and 19 months, respectively. The objective response rate (CR + PR) and tumor control rate (CR + PR + SD) were 57% and 79%, respectively, with two patients alive after 5 years; toxicities included thrombocytopenia, neutropenia, and capillary leak syndrome. CONCLUSIONS: Our study builds on previous studies utilizing TAG in adult leiomyosarcoma (LMS) by focusing on AYA, non-LMS sarcomas, especially OST. Our experience suggests that TAG is well tolerated and has activity in very high risk sarcomas in AYA.

Family Refusal of Chemotherapy for Pediatric Cancer Patients: A National Survey of Oncologists.

BACKGROUND: Refusal of therapy is ethically acceptable for competent adults. Practitioner opinions regarding refusal of therapy in pediatric cancer patients has not been widely studied. This is the largest survey of oncology practitioners assessing support for refusal of chemotherapy. PROCEDURE: Pediatric oncology nurses/physicians were asked: "As their provider I would support refusal of chemotherapy by a family," with the following options: "Never support refusal," "Always support refusal," or "Support for refusal would depend on cure rate, age, or both." Variables assessed were: age (0 to 7, 8 to 13, 14 to 17 y) and cure rate (0% to 33%, 34% to 66%, 67% to 100%). RESULTS: A total of 957 practitioners responded. Fifty-six percent, 31%, and 0.2%, respectively, stated their support of chemotherapy refusal depended on "age and cure rate," "cure rate alone," or "age alone." Two percent and 11% indicated they would "always" or "never" support refusal, respectively. For a "modest" or "good" cure rate, support for refusal was <20%, whereas for a "poor" cure rate, the majority would support a family's refusal (53% to 78% age dependent). Within each cure rate, respondents were more likely to support refusal for older patients (P<0.001). CONCLUSIONS: The majority of practitioners surveyed viewed parental refusal of chemotherapy for children with a moderate or good expected cure rate as unacceptable, but were more accepting of refusal with a poor prognosis, especially for teenagers.

Metastatic osteosarcoma to the interventricular septum: an unusual presentation in a child.

Whereas primary cardiac tumors are reported in only 0.17 % of pediatric patients, malignant cardiac tumors are even less common in children. This report presents a 10-year-old child with relapsed osteosarcoma manifesting as metastatic lesions to the interventricular septum.
