S3306 Vanishing Bile Duct Syndrome: A Case Report

Davood Karimi Hosseini, Ethan Burg, Max Edeson, Gabrielle K. Sharbin et autres

Introduction: Pancreaticopleural fistula (PPF) represents a rare yet formidable complication of chronic pancreatitis, resulting from a pathological communication between the pancreatic ductal system and the pleural cavity. Accounting for approximately 0.4% of all pancreatitis cases, PPF often arises from longstanding ductal inflammation …

S3307 Multiple Myeloma Relapse With Pancreatic Plasmacytomas: A Case Report

Gabrielle K. Sharbin, Max Edeson, Ethan Burg, Hanieh K. Hosseini et autres

Introduction: Extramedullary plasmacytomas (EMPs) are rare tumors of neoplastic plasma cells with minimal or no bone marrow involvement. They occur in ∼5% of multiple myeloma (MM) cases, often reflecting disease progression. EMPs typically affect the head, neck, or upper respiratory tract, while …

S5774 Rapidly Progressive Multisystem Organ Failure Due to EBV+ Primary Hepatic PTCL

Max E. Edeson, Ethan Burg, Gabrielle K. Sharbin, Davood Karimi Hosseini et autres

Introduction: Peripheral T-cell lymphoma (PTCL) is a rare, aggressive form of Non-Hodgkin Lymphoma. Hepatosplenic/primary hepatic PTCL (HSPTCL) is a rarer subtype, <1% of cases. It typically occurs in males aged 35 on immunosuppression, with no clear etiology, although associated with infections like …

Autoimmune pancreatitis masquerading as a pancreatic neoplasm: A case report

Gabrielle K. Sharbin, Max E. Edeson, Ethan Burg, Hanieh K. Hosseini et autres

RATIONALE: Acute pancreatitis is common with potential serious sequela; representing the 5th leading cause of in-hospital mortality. Autoimmune pancreatitis (AIP) is rare, separated into type 1 and type 2 AIP. Type 1 AIP is associated with systemic immunoglobulin G4 related disease (IgG4-RD) …

The Yoneda embedding in simplicial type theory

Daniel Gratzer, Jonathan D. Weinberger, Ulrik Torben Buchholtz

Riehl and Shulman [1] introduced simplicial type theory (STT), a variant of homotopy type theory which aimed to study not just homotopy theory, but its fusion with category theory: (∞, 1)-category theory. While notoriously technical, manipulating ∞-categories in simplicial type theory is …

Transverse myelitis as a rare paraneoplastic manifestation of a pancreatic tail adenocarcinoma: A case report

Ethan Burg, Gabrielle K. Sharbin, Max E. Edeson, Hanieh K. Hosseini et autres

RATIONALE: Transverse myelitis (TM) is a non-compressive myelopathy caused by spinal cord inflammation that can present with motor, sensory and autonomic deficits. Paraneoplastic TM represents a rare etiology of TM caused by autoantibodies targeting the spinal cord in the setting of malignancy, …

The Yoneda embedding in simplicial type theory

Daniel Gratzer, Jonathan D. Weinberger, Ulrik Torben Buchholtz

Riehl and Shulman introduced simplicial type theory (STT), a variant of homotopy type theory which aimed to study not just homotopy theory, but its fusion with category theory: $(\infty,1)$-category theory. While notoriously technical, manipulating $\infty$-categories in simplicial type theory is often easier …

Management of gastrointestinal bleed in the intensive care setting, an updated literature review

Vignesh Krishnan Nagesh, Sai Priyanka Pulipaka, Ruchi Bhuju, Emelyn Martinez et autres

Gastrointestinal (GI) bleeding is a critical and potentially life-threatening condition frequently observed in the intensive care unit (ICU). This literature review consolidates current insights on the epidemiology, etiology, management, and outcomes of GI bleeding in critically ill patients. GI bleeding remains a …

On a fibrational construction for optics, lenses, and Dialectica categories

Matteo Capucci, Bruno Gavranović, Abdullah Malik, Francisco Rios et autres

Categories of lenses/optics and Dialectica categories are both comprised of bidirectional morphisms of basically the same form. In this work we show how they can be considered a special case of an overarching fibrational construction, generalizing Hofstra's construction of Dialectica fibrations and …

S3594 Gastric Ulcer Disease Presenting as Acute Pancreatitis

Boris Livitz, Alana Barofsky, Nazir Ahmed, Shawn Philip et autres

Introduction: Acute pancreatitis is diagnosed based on the Atlanta criteria: i) typical pain, ii) serum lipase/amylase levels greater than 3 times, and/or iii) characteristic imaging findings. In addition to pancreatitis, lipase levels are also elevated in small-bowel, hepatobiliary and renal pathology in …
