Faculty, Staff and Student Publications

Infantile fibrosarcoma (IF) is a rare malignant fibroblastic tumor that affects infants and young children, occurring most commonly in the extremities. Here, we present a 14-year-old patient with an abdominal mass incidentally detected after a blunt injury to the abdomen. The initial trauma protocol CT revealed a high attenuation mesenteric lesion in the left central abdomen suggestive of mesenteric hematoma. However, the possibility of a solid neoplastic mass lesion could not be excluded. Further evaluation with dynamic contrast-enhanced serial MRI showed a progressive enhancing mass and excluded a hyperacute hematoma with active bleeding. The mass was resected, and histopathological examination …

Breast Cancer In A Teenage Girl With Brca Mutation: A Case Report From A Low Middle-Income Country, Lubna Mushtaque Vohra, Danish Ali, Syeda Amrah Hashmi, Meher Angez

Section of General Surgery

Introduction: A staggering majority of pediatric breast masses are benign (mostly fibroadenoma) and so a biopsy is not readily performed as it can potentially lead to a future breast disfigurement. However, this should not be standard practice as this can lead to a delayed diagnosis, and hence, the treatment of pediatric breast cancer (BC); this was also seen in our patient's scenario.
Case history: Here, we report the case of the youngest known breast cancer patient in Pakistan, a 15-year-old girl. The right-sided breast lump which was diagnosed clinically as a fibroadenoma later turned out to be stage IIb pT3N0M0 …

Department of Paediatrics and Child Health

Rasmussen aneurysm is rare diagnosis occurring in patients with long-standing tuberculosis. TB-COVID-19 co-infection in the context of Rasmussen aneurysm is a rare occurrence, yet new cases are emerging. An elderly male was recently diagnosed with TB-COVID-19 co-infection and presented with sudden onset massive hemoptysis. The patient was diagnosed with Rasmussen aneurysm after being evaluated by computed tomography pulmonary angiogram due to a suggestive clinical presentation. Interventional radiologists planned for embolization of pulmonary artery, with an unidentifiable source. It was suspected that the patient's source of bleeding was hampered due to local tamponade effect or thrombosis of the aneurysm. The patient …

Are Body Surface Area Based Estimates Of Liver Volume Applicable To Children With Overweight Or Obesity? An In Vivo Validation Study., Chelsea Hosey-Cojocari, Sherwin S. Chan, Chance S. Friesen, Amie L. Robinson, Veronica Williams, Erica Swanson, Daniel O'Toole, Jansynn Radford, Neil J. Mardis, Trevor N. Johnson, J Steven Leeder, Valentina Shakhnovich

Manuscripts, Articles, Book Chapters and Other Papers

The liver is the primary organ responsible for clearing most drugs from the body and thus determines systemic drug concentrations over time. Drug clearance by the liver appears to be directly related to organ size. In children, organ size changes as children age and grow. Liver volume has been correlated with body surface area (BSA) in healthy children and adults and has been estimated by functions of BSA. However, these relationships were derived from "typical" populations and it is unknown whether they extend to estimations of liver volumes for population "outliers," such as children with overweight or obesity, who today …

Implementing A Clinical Practice Guideline For Pediatric Appendicitis Safely Reduced Health Care Use And Improved Antimicrobial Stewardship, Jack Vernamonti, Robin Cotter, Jennifer Jubulis, Kartikey Pandya

Journal of Maine Medical Center

Introduction: Appendicitis is the most common emergency surgical disease in children. Those with perforated appendicitis have a more complicated and varied course. Through a clinical practice guideline (CPG), we sought to reduce computed tomography scans, laboratory draws, and exposure to broad-spectrum antibiotics without adversely affecting length of stay, hospital readmission, or repeat antibiotic administration.

Methods: Electronic records were retrospectively reviewed before and after CPG implementation, and data was collected in REDCap.

Results were reported as mean or percent incidence, and statistical analysis was done using a Student’s t-test, Mann-Whitney U test, or Pearson’s χ2 with P < .05 considered significant. Results: One hundred patients with a perforated appendix (50 before and 50 after CPG implementation) were included in our analysis. Length of stay (4.98 vs 4.46 days; P = .25), hospital readmission rate (10% vs 14%; P = .54), and additional antibiotic administration (2% vs 4%; P = .56) did not change. We observed no difference in the Pediatric Appendicitis Score (9 vs 9; P = .48) and a trending increase in evaluation at an outside hospital (56% vs 74%; P = .06). Rates of computed tomography scans did not differ overall (50% vs 40%; P = .31), but showed a decreasing trend at our institution (30% vs 12%; P = .06). We also found fewer post-operative laboratory studies (90% vs 38%; P < .01) and patients who received broad-spectrum intravenous antibiotics (92% vs 18%; P < .01).

Discussion: Through implementing the …

Critical Need For Pharmacologic Treatment Options In Nafld: A Pediatric Perspective., Chance S. Friesen, Sherwin S. Chan, Jonathan B. Wagner, Chelsea Hosey-Cojocari, Iván L Csanaky, Valentina Shakhnovich

Manuscripts, Articles, Book Chapters and Other Papers

Nonalcoholic fatty liver disease (NAFLD) affects up to 70% of children with obesity and has become the number one etiology for liver transplant in the United States. Early, effective intervention is critical to prevent disease progression into adulthood. Yet, it is seldom achieved through lifestyle modification alone. Thus, children must be included in NAFLD pharmacology trials, which, to date, continue to focus primarily on adult populations. This commentary serves as a call to action.

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: Tisagenlecleucel, an anti-CD19 chimeric antigen receptor T (CAR-T) cell therapy, has demonstrated durable efficacy and a manageable safety profile in pediatric and young adult patients with relapsed/refractory B-cell acute lymphoblastic leukemia (B-ALL) in the ELIANA pivotal trial and real-world experience. Experience from investigator-led studies prior to ELIANA suggests that infections and inflammatory conditions may exacerbate the severity of cytokine release syndrome (CRS) associated with CAR-T cell therapy, leading to extreme caution and strong restrictions for on-study and commercial infusion of tisagenlecleucel in patients with active infection. CRS intervention with interleukin (IL)-6 blockade and/or steroid therapy was introduced late in …

A Neonate With Upper Gi Bleeding, Suneeta Khemani, Huma Ghulam Qadir, Mumtaz Malik, Faiqa Hassan

Department of Paediatrics and Child Health

Bleeding in the newborn is often a serious problem because of cardiovascular effects associated with a loss of blood and/or the damaging effects of bleeding on neonatal tissues, especially the brain. Gastric polyps are described as abnormal lesions that originate in the gastric epithelium or submucosa and protrude into the stomach lumen. Clinical presentation of gastric polyps in children varies widely, from incidental endoscopic finding to massive gastrointestinal bleeding. However, acute gastrointestinal bleeding in association with hyperplastic gastric polyps has been reported very rarely. We report a case of unusual upper gastrointestinal bleeding in newborn baby on 2nd day of …
