Not All That Hurts Is Malignant: A Painful Case Of Focal Nodular Hyperplasia, Zamanali Khakhar, Abdullahi Abdigafar Yunis, Dayib Buthul, Khadija Warfa, Soraiya Manji, Rajiv Patel, Sayed Ali Raza Bukhari

Imaging & Diagnostic Radiology, East Africa

Focal nodular hyperplasia (FNH) is a benign hepatic lesion most often detected incidentally during imaging studies. While typically asymptomatic, a small subset of patients may present with abdominal pain or discomfort. Clinically and radiologically, FNH can mimic malignant liver tumors, occasionally resulting in unnecessary invasive procedures. This case report describes a 45-year-old woman with symptomatic FNH who was placed on routine imaging surveillance and managed conservatively. This case underscores the importance of accurately distinguishing this benign condition from hepatic malignancies. It further highlights the diagnostic challenges associated with achieving a definitive diagnosis.

Porokeratosis Ptychotropica Mimicking A Herpes Simplex Virus Infection, Erin R. Pomerantz, Jayci G. Rhein, Jason B. Lee, Sylvia Hsu

Department of Dermatology and Cutaneous Biology Faculty Papers

Introduction

Porokeratosis encompasses a group of skin disorders characterized by abnormal keratinization, with the defining histologic feature of cornoid lamellae, which are stacks of parakeratotic cells that overlie dyskeratotic keratinocytes. Several subtypes of porokeratosis have been identified, including disseminated superficial actinic porokeratosis, porokeratosis of Mibelli, linear porokeratosis, porokeratosis palmaris et plantaris disseminata, punctate porokeratosis, and porokeratosis ptychotropica (PP).¹ Although risk factors for other forms of porokeratosis, such as UV exposure, immunosuppression, and genetic predisposition, have been identified, PP remains less understood. Clinically, PP typically presents as hyperkeratotic, verrucous plaques found bilaterally in the gluteal cleft and buttocks.^{2, …}

Challenges And Opportunities With Providing Genetic Testing And Counseling For Mucopolysaccharidosis Type Ii In Kenya, Lucy Mungai, Charles Njeru, Allan Njoroge, Michuki Maina, Syokau Ilovi, Dalton Wamalwa, Ruth Nduati, Beatrice Odongkara, Danny Miller

Pathology, East Africa

Background Limited or absent genetic counseling and testing resources in low- and medium-income countries lead to missed or late diagnoses for treatable metabolic conditions with irreversible complications. In some communities, misunderstanding about the etiology of a genetic condition may lead women whose children are affected to be viewed as a bad omen and become stigmatized or ostracized from their community. Mucopolysaccharidosis type II (MPS II), or Hunter syndrome, is a lysosomal storage disorder in which deficiency or inactivity of the enzyme iduronate-2-sulfatase leads to accumulation of glycosaminoglycans throughout the body. The diagnosis can be made through clinical assessment, enzyme activity …

Pediatric Heart-Kidney Transplantation, Swati Choudhry, Kriti Puri, Vikas R Dharnidharka

Faculty, Staff and Students Publications

Heart transplantation is regarded as the definitive treatment for advanced pediatric heart failure. However, concomitant kidney dysfunction often complicates candidate selection for isolated heart transplantation. Prolonged venous congestion, nephrotoxic exposures, and recurrent episodes of acute kidney injury can result in varying degrees of renal impairment. Differentiating between reversible kidney injury secondary to cardiorenal syndrome and irreversible intrinsic renal disease remains a major challenge. Pediatric heart-kidney transplantation has shown survival benefits for patients with end-stage heart failure requiring chronic dialysis, yet its role in patients with less severe renal dysfunction is less clearly defined. This review summarizes the current evidence on …

This study presents a deep learning object detection model and mobile application designed to classify distal radius radiographs into standard views-anterior-posterior (AP), lateral (LAT), and oblique (OB)- while localizing the anatomical region most relevant to distal radius fractures. A total of 1593 deidentified radiographs were collected from a single institution between 2021 and …

Association Of Preoperative Nocturnal Hypoxaemia Nadir And Fentanyl Ventilatory Sensitivity In Children With Obstructive Sleep Apnoea Undergoing General Anaesthesia: A Multicentre Clinical Cohort Study, Adam C Adler, Elaina E Lin, Anna H Messner, Tara L Rosenberg, Shelly Pecorella, Aidan Keleghan, Spencer Faircloth, T Wesley Templeton, Lynnette Harris, Sabina A Khan, Greesha S Pednekar, Duc T Nguyen, Arvind Chandrakantan, Britta S Von Ungern-Sternberg

Faculty, Staff and Students Publications

Background: Obstructive sleep apnoea (OSA) has been thought to increase the risk of respiratory depression from opioids. The primary aim of this study was to assess whether preoperative hypoxaemia by sleep study pulse oximetry imparts greater opioid sensitivity.

Methods: A multicentre observational cohort study with in-cohort dose randomisation was performed in children 2-8 yr of age with OSA undergoing adenotonsillectomy. Ninety patients were assigned to one of two Spo2 cohorts by preoperative sleep study Spo2 nadir of < or ≥85% to receive fentanyl 1.0 or 1.5 μg kg-1 (maximum 25 μg) after sevoflurane induction. The primary outcome was the extent of opioid-induced central ventilatory depression over time by Spo2 status as defined by the differences in tidal volume, respiratory rate, end-tidal CO2, and minute ventilation for 10 min after fentanyl administration when compared with pre-fentanyl baseline values. Secondary outcomes included assessment of body mass index, fentanyl dose, sex, age, and race on opioid-induced central ventilatory depression. Intention-to-treat and per protocol analysis were performed.

Results: Ninety patients underwent in-cohort randomisation (Spo2 < 85%; n=47 and Spo2 ≥85%; n=43). Final per protocol analysis included 73 subjects, fentanyl 1.0 μg kg-1 (Spo2 < 85%; n=36 and Spo2 ≥85%; n=37) and 15 subjects, fentanyl 1.5 μg kg-1 (Spo2 < 85%; n=9 and Spo2 ≥85%; n=6). Multivariable mixed effect model for the primary outcomes (tidal volume, respiratory rate, end-tidal CO2, and minute ventilation) from baseline to 10 min (as % change per minute) were not different between groups by Spo2 nadir (< or ≥85%) and fentanyl dose for the intention-to-treat and per protocol analyses.

Conclusions: Single-dose fentanyl ventilatory effects in paediatric OSA patients during sevoflurane anaesthesia were not associated with …

The pathogenesis of immune thrombocytopenia (ITP) is complex and incompletely understood. Multiple cell types have been implicated, and their respective contribution is unclear. A recent genome-wide association study identified single-nucleotide polymorphisms (SNPs) associated with pediatric ITP within or near 5 genes in the canonical Wnt signaling pathway. To investigate whether this pathway was dysregulated in ITP and identify which cell types were involved, we leveraged extensive functional genomics and single-cell RNA sequencing (scRNA-seq) data. By linking the identified SNPs to likely regulated genes, we showed an enrichment in the Wnt pathway and identified 2 additional genes in this pathway involved …

Recognition of foreign RNA is critical for the innate immune response to viruses. Interferon (IFN)-induced proteins with tetratricopeptide repeats (IFIT) 2 and 3 are highly upregulated following viral infection, but mechanistic insight into their antiviral role is lacking. Here we demonstrate that short 5' untranslated regions (UTRs), a characteristic of many viral mRNAs, can serve as a molecular pattern for innate immune recognition via IFIT2 and IFIT3. Structure determination of the IFIT2-IFIT3 complex at 3.2 Å using cryo-EM reveals a domain-swapped heterodimer that is required for recognition of the viral mRNA 5' end, translation inhibition and antiviral activity. Critically, viral …

Faculty, Staff and Students Publications

Vascular calcification (VC), a common complication associated with diabetes mellitus (DM), substantially increases the risk of cardiovascular diseases and is associated with elevated mortality in individuals with DM. Endothelial-to-mesenchymal transition (EndMT) imparts phenotypic plasticity to vascular endothelial cells (VECs), granting them the potential for osteogenic differentiation, which is a crucial mechanism in regulating VC. Notably, adenosine-ADORA2A-mediated endothelial dysfunction plays a pivotal regulatory role in cardiovascular diseases. However, the specific role of endothelial ADORA2A in diabetic VC remains to be elucidated. In this study, we found that ADORA2A was upregulated in the endothelium of diabetic mice and cultured human aortic endothelial …

Can Interpersonal Trust Predict And Account For Symptom Change During Group Cognitive Processing Therapy For Ptsd? An Investigation Of The Iterated Trust Game, M Wright Williams, Christopher Hunt, David P Graham, Matt Estey, Lia Smith, Katherine Mccurry, Brooks King-Casas, Pearl Chiu

Faculty, Staff and Students Publications

Objective: Group cognitive processing therapy (GCPT) is frequently utilized to treat PTSD within the VA healthcare system, but its mechanisms are not well understood. Interpersonal trust could be an important change process in GCPT given its relevance to group-based therapy and its role in CPT, but self-report measures are inadequate for capturing the dynamic interplay that defines interpersonal trust. Here, we examined the degree to which interpersonal could predict and account for PTSD symptom change in GCPT using the iterated trust game (ITG)-a behavioral task used to approximate real-world trust behavior.

Methods: Participants were Veterans with PTSD who participated in …
