Complex Regional Pain Syndrome In A 21-Year-Old Male Patient Following A Gunshot Wound (Gsw), Jonathan Rodriguez, Oyinkansola Mudasiru, Alexandria Armstrong, Hooman Tabatabai-Mir

School of Podiatric Medicine - Student Research

Purpose: Complex Regional Pain Syndrome (CRPS) is a pain disorder that typically follows several forms of trauma, including surgery or fractures. The diagnostic gold standard for CRPS is the Budapest diagnostic criteria. In the general population, CRPS is 3-4 times more common in middle-aged women. Regarding incidence following injury, it most often occurs after a fracture. CRPS secondary to ballistic trauma is rarer, particularly in the case of a young male individual. The purpose of our case study is to follow a 21-year-old male patient who suffered an accidental self-inflicted gunshot wound to the left foot and detail the presentation …

Occupational Epidemiology Of Acral Lentiginous Melanoma, Lily Guo, Robin Kikuchi, April W. Armstrong, Suephy C. Chen

Department of Dermatology and Cutaneous Biology Faculty Papers

Acral lentiginous melanoma (ALM) classically presents in glabrous skin. Some studies suggest an association between mechanical stress and ALM development. People working jobs with long periods of standing/walking may be exposed to near-daily mechanical stress. To investigate the relationship between occupation type and ALM development, we performed a retrospective cohort study using Optum’s Clinformatics Database (2007—2023). We compared the risk of ALM in adults with occupational data (n = 9,270,935). Retired patients had the highest prevalence (0.081) and incidence per 1,000,000 person-years (0.514, 95% confidence interval = 0.487—0.542) of ALM. We performed multivariate logistic regression, adjusted for demographics and insurance, …

Trauma-Related Compulsions In Obsessive-Compulsive Disorder: Functional Insights From Factor Analysis, Caitlin M Pinciotti, Max Thorsson, Gregor Horvath, Matti Cervin

Faculty, Staff and Students Publications

Resisting obsessive-compulsive disorder (OCD) compulsions is a key predictor of exposure and response prevention (ERP) effectiveness, yet trauma-exposed individuals with OCD endorse more severe compulsions and are more likely to be labelled 'treatment resistant.' Among trauma-exposed individuals, compulsions are theorised to function to prevent future trauma and cope with trauma-related responses. Recent findings suggest that certain compulsions in the context of trauma exposure differentially impact treatment outcomes, yet missing from extant literature is a larger empirically derived conceptualisation for how trauma may impact the underlying function of compulsions. In a sample of 662 adult patients enroled in intensive OCD treatment …

Utility Of Diagnostic Arthroscopy Before Medial Patellofemoral Ligament Reconstruction In Pediatric And Adolescent Patients Without Articular Findings On Magnetic Resonance Imaging, Holden Archer, Kaleb Patterson, Jonathan D Schwartzman, Scott D Mckay, Indranil Kushare

Faculty, Staff and Students Publications

BACKGROUND: Medial patellofemoral ligament (MPFL) reconstruction is frequently used to manage recurrent patellar instability. Diagnostic arthroscopy is commonly performed before MPFL reconstruction to identify, confirm, and address intra-articular pathology. However, when preoperative magnetic resonance imaging (MRI) does not demonstrate intra-articular lesions, it is unclear how often diagnostic arthroscopy in pediatric patients alters surgical management.

PURPOSE: To determine the utility of diagnostic arthroscopy in young patients undergoing MPFL reconstruction who had no intra-articular chondral or osteochondral pathology, meniscal tears, or loose bodies identified on preoperative MRI, and to characterize intra-articular pathology detected on arthroscopy but not identified on MRI.

Posterior fossa type A (PFA) ependymoma is an unusual infantile brain tumour with few known somatic mutations, thought to be driven by epigenetic mechanisms1. PFA ependymoma has a markedly higher incidence and worse prognosis in male children than in female children2. The mechanisms that underlie these sex differences are at present unknown. Here we show that the cellular hierarchy of PFA ependymoma is less differentiated in male individuals than it is in female individuals. In the normal developing mouse hindbrain, male gliogenic progenitors are less differentiated than matched female sibling controls. To further parse the effects …

Confessions In Cases Of Child Physical Abuse-A Capnet Study, Margaret R Russell, Antoinette L Laskey, Henry T Puls, Suzanne P Starling, Joanne N Wood, Daniel M Lindberg, Nancy S Harper, Caitlin R Mcnamara, Angela N Bachim, Farah W Brink, Lori D Frasier, James D Anderst, Porcia Vaughn, Kristine A Campbell

Faculty, Staff and Students Publications

Objective: Prior research on confessions of physical abuse (PA) has explored mechanisms of injury. Little is known about conditions supporting a confession of abuse or how confessions may influence case outcomes.

Methods: This cross-sectional study of suspected PA in children aged < 10 years at 10 centers participating in CAPNET, a multicenter child PA research network, included children with in-person Child Abuse Pediatrics (CAP) consultations between February 2021 and December 2022 and excluded children without injury. Our focus was a confession of inflicted injury known to the CAP during clinical involvement. We compared child and clinical characteristics, out-of-home (OOH) placements, and arrests between cases with and without confessions. Multivariable models using generalized estimating equations (GEE) produced adjusted predicted probabilities (APP) clustering by CAPNET site.

Results: Confessions were known to CAPs in 115/4297 (2.7%) cases, with significant site variability. In a multivariable GEE model, confessions were more likely in cases with injuries with high specificity for abuse (APP 6.0% vs 1.6%, P < .001), near-fatality (APP 5.6% vs 2.3%, P < .001), and older children (APP 4.8% vs 2.5%, P = .025). OOH placements and arrests were more common in cases with confessions. CAP awareness of confessions, OOH placements, and arrests did not follow racial or ethnic patterns seen in the US child welfare system. Lower socioeconomic status was associated with OOH placements and arrests but not with CAP awareness of confessions.

Conclusions: Our findings highlight differences in case characteristics and outcomes where a confession is known to the CAP and raise questions about …
