From Charcuterie Board To Clinical Ward: Pediococcus Pentosaceus As An Emerging Wound Pathogen - A Scoping Review, Jessica Sima, Mariana Rodriguez, Stephanie Campbell, Amanda Killeen

School of Podiatric Medicine - Student Research

Currently, there are 12 known species of Pediococcus, with P. Acidilactici and P. pentosaceus being the most well-known. P. pentosaceus is a Gram-positive, lactic acid bacterium, and is most often recognized for its wide usage as a probiotic and fermenter of wines and cheeses. It is also studied for its anti-inflammatory effects and antimicrobial properties against many common pathogens, such as Salmonella, Clostridium difficile, E.coli, etc.  However, the Pediococcus species can be an opportunistic pathogen in immunocompromised patients, and its resistance to glycopeptides and tetracycline limits treatment options.

We conducted a scoping review using Google Scholar and PubMed with the …

A Novel Guide‑Free Internal Device Fixation For Transverse Tri‑Planar Distal Metatarsal Osteotomy: A Retrospective Review​, Maya D. Kaafarani, Brittney White, Graham A. Hamilton, Shannon M. Rush

School of Podiatric Medicine - Student Research

Introduction: Minimally invasive surgery (MIS) for bunion correction has gained popularity due to favorable outcomes and reduced recovery times. However, most MIS techniques rely on commercial instrumentation for osteotomy, reduction, and fixation. This retrospective study evaluates patients treated with a novel tri-planar distal metatarsal osteotomy performed without specialized MIS guides, using only standard surgical tools and a novel device.

Methods: A retrospective review was conducted on 28 patients (31 procedures, including 3 bilateral cases) who underwent MIS bunion correction from 2021 to 2024. The technique involved a 2–3 cm medial incision, transverse osteotomy at the distal surgical neck of the …

Glp-1 Receptor Agonists In Diabetic Foot And Ankle Care: Skeletal Liability Or A Blessing In Disguise? A Scoping Review, Daniela Lizbeth Avilez, Amanda Killeen

School of Podiatric Medicine - Student Research

Introduction: Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) are increasingly prescribed for glycemic control and weight reduction in patients with Type 2 Diabetes Mellitus (T2DM). Patients with T2DM exhibit elevated fracture risk despite preserved bone mineral density due to impaired bone quality and microarchitectural compromise. Whether GLP-1 RA therapy exacerbates or mitigates skeletal risk remains clinically relevant to podiatric care.

Hypothesis: We hypothesized that GLP-1 RA therapy is not associated with increased lower extremity fracture risk and may demonstrate protective trends influenced by age and duration of therapy.

Methods: A review of PubMed and Google Scholar (2010–2026) was conducted. Inclusion criteria …

Rearfoot Realignment As A Prophylactic Strategy For Recurrent Lateral Column Ulcers In Diabetic Foot: A Case-Based Hypothesis, Christopher I. Anjorin Ms Dpmc, Ali-Abdul Kareem Dpm

School of Podiatric Medicine - Student Research

Lateral column ulcerations remain a persistent and complex challenge in diabetic foot management. Although procedures such as tailor’s bunionectomy may provide localized pressure relief, they often fail to address the underlying biomechanical contributors, most notably rearfoot deformities such as calcaneal varus or pes cavovarus frequently observed in diabetic patients. These structural abnormalities shift the weight‑bearing axis laterally, increasing ground reaction forces along the fifth metatarsal and predisposing individuals with diabetic peripheral neuropathy and impaired proprioception to recurrent ulceration. This case explores the hypothesis that prophylactic rearfoot realignment may offer superior long‑term outcomes by correcting the mechanical etiology of lateral column …

Selective Retention Of Birdshot Pellets In The Rearfoot: A Case Demonstrating Tissue Preservation And Functional Recovery, Yasim Zafar, Steven Bolton, Alexandria Armstrong, Hooman Mir

School of Podiatric Medicine - Student Research

Level of Evidence: III (Case Study)

Statement of Purpose: Gunshot wounds to the foot pose a unique surgical dilemma—whether to pursue aggressive foreign body removal or to preserve soft tissue integrity. This case highlights the management of a birdshot injury to the rearfoot where selective non-removal of pellets near the neurovascular bundle led to complete healing and full functional recovery. The purpose is to emphasize tissue preservation over aggressive exploration in complex ballistic foot injuries.

Case Study: A 26-year-old female sustained a birdshot gunshot wound to the right rearfoot. Multiple small entry wounds were noted on the posterior and plantar …

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 …

Foot And Ankle Biomaterials: A Comprehensive Review Of Current Applications, Challenges, And Future Directions, Peter Elvin, Amayrani Sanchez, Anthony Allen Reyes, Hagner L. Andrade, Meelad Karami, Hooman Mir, Javier La Fontaine, Danieli Rodrigues, Claudia Biguetti

School of Podiatric Medicine Publications

Metallic biomaterials enable successful reconstruction and fixation of skeletal tissues by supporting repair, load-bearing function, and anatomical alignment in foot and ankle surgery. However, the unique anatomic and biomechanical demands of this region, combined with challenging pathologies such as flatfoot and Charcot neuroarthropathy, present distinct challenges, with effective intervention requiring targeted biomaterial solutions and precise indications. Furthermore, metallic biomaterials currently represent the most predominant and clinically validated fixation systems in foot and ankle surgical reconstructions, while also generating the largest body of outcome-based evidence. This review summarizes and discusses their contemporary applications, outcomes, limitations, unmeet needs, and future directions based …

Methods: We used Scopus to …

Multiplanar First-Ray Deformity And Its Impact On Tibial Sesamoid Assessment: A Radiographic Analysis​, Yasim Zafar, Madelaine Adkins, Jessica Sima

School of Podiatric Medicine - Student Research

This study evaluated whether discrepancies in tibial sesamoid position (TSP) between anteroposterior (AP) and sesamoid axial radiographs are associated with first-ray deformity parameters: first metatarsal rotation angle (MRA), sesamoid rotation angle (SRA), intermetatarsal angle (IMA), and hallux valgus angle (HVA). We hypothesized that increased frontal-plane external rotation of the first metatarsal would be the primary contributor to AP–axial TSP mismatch.

This secondary analysis used deidentified radiographs from Shibuya et al. (J Foot Ankle Surg. 2019). Adults aged 18–80 with measurable TSP on both AP and axial views were included; patients with prior foot trauma or osseous surgery were excluded. Only …

Midfoot Reconstruction For Avascular Necrosis Of The Navicular Bone​, Jessica Sima, Srilalitha Lanka, Merlin Sajeev, Shannon Rush, Graham Hamilton

School of Podiatric Medicine - Student Research

Background: Avascular necrosis (AVN) of the tarsal navicular, particularly with collapse, presents a complex surgical challenge due to compromised vascularity and the need to restore medial column length. This retrospective case series evaluates three distinct surgical approaches to midfoot reconstruction in patients with navicular AVN.

Methods: Three patients with navicular AVN were treated using individualized grafting strategies. Etiologies included chronic protease inhibitor use for HIV, Müller-Weiss syndrome, and post-resection of a giant cell tumor. All procedures utilized a medial utility incision with debridement to viable bleeding bone. Two cases were reconstructed using a combination of proximal tibial autograft, patellar allograft, …

Liposclerosing Myxofibrous Tumor Of The Foot: A Case Report, Mohammad Junayed Khan, Sufiyan Mannan Ahmed, Asad Mustafa, Sairah Asghar, Mohammad Tanjim Hossain

School of Podiatric Medicine - Student Research

Statement of Purpose: This case presents a rare sclerosing-type atypical lipomatous tumor with myxomatous features—the first and only known reported case of an ALT in the foot—along with its pathology, treatment, and management.

Case Study: Atypical lipomatous tumor/well-differentiated liposarcoma (ALT/WDL) represents the most common liposarcoma subtype, with recurrence and dedifferentiation risk influenced by tumor location. Retroperitoneal tumors recur frequently, while those in the lower extremity rarely do. Liposarcoma of the foot is exceedingly rare.

A 61-year-old male presented with a slowly enlarging, mildly tender lump on the right plantar heel. Radiographs demonstrated a 3 cm oval soft-tissue thickening without calcification. …

Bone Healing During A Dysregulated Inflammatory Phase: Comparative Skeletal Features In 5-Lipoxygenase Knockout And Wild Type Mice, Marco Hernandez, Nidhin John, Bhuvana L. Chandrashekar, Mariza A. Matsumoto, Naohiro Shibuya, Claudia Biguetti

School of Podiatric Medicine - Student Research

Background: High-risk patients, such as those with diabetic neuropathy, often experience prolonged and dysregulated inflammation during bone healing. The 5-lipoxygenase (5LO) pathway is a key mediator of inflammation and bone resorption and may influence these outcomes. Therefore, understanding the skeletal features associated with 5LO genetic deletion may help identify therapeutic opportunities to improve healing in high-risk patients.

Objective: To determine how genetic deletion of 5LO affects skeletal structure and macrophage phenotypes, with the goal of identifying therapeutic targets to improve bone healing in high-risk patients.

Materials and Methods: A total of 10, adult (3 months old), 129/SvEv male mice were …

Comparative Analysis Of M1 And M2 Macrophage Distribution And Localization In Chronic Wounds Of Metabolically Healthy And Diabetic Hosts Using A C57bl/6 Mouse Model, Bryan Liu, Ramiro Cisneros, Nathaniel Primous, Estephania Garcia, Bhuvana Lakkasetter Chandrashekar, Claudia Biguetti

School of Podiatric Medicine - Student Research

Introduction/Purpose: Type 2 diabetes and obesity are major risk factors for delayed wound healing in chronic foot ulcers. This study investigated whether a high-fat diet induces diabetes-like metabolic dysfunction in mice and characterized associated morphological changes and macrophage polarization during wound healing. Macrophages exist as pro-inflammatory M1 and anti-inflammatory M2 phenotypes that regulate tissue repair.

Methods: Ten male C57BL/6J mice (8 weeks old) were divided into high-fat diet (HFD) and regular diet (RD) (IACUC Protocol 22-33) groups.  After 12 weeks, body weight and intraperitoneal glucose tolerance test were measured to confirm metabolic phenotypes, after which a 6mm dorsal excision wound …

Expression Of 5-Lo In Chronic Wounds In A Preclinical Murine Model Of Obesity And Type 2 Diabetes, Joshua Wu, Ramiro Cisneros, Nathaniel Primous, Estephania Garcia, Bhuvana Lakkasetter, Claudia Biguetti

School of Podiatric Medicine - Student Research

Introduction: Diabetes is associated with impaired wound healing and a high incidence of chronic, non-healing ulcers, largely driven by persistent low-grade inflammation. Leukotriene B4 (LTB4), a product of the 5-lipoxygenase (5-LO) pathway, has emerged as a key mediator of this chronic inflammatory state. Hence, this study investigated the role of the 5-LO pathway in cutaneous wound healing under normoglycemic and diabetic conditions using a murine model.

Methods: Twelve 8-week-old male C57BL/6J mice were fed with high-fat diet (HFD; 60% kcal fat) or low-fat diet (LFD; 10% kcal fat) for 12 weeks (IACUC 22-33). Body weight (BW) and fasting blood glucose …
