Delegate Framework For Decoupling Navigation Ui Generation And Layout, Rakhi Parekh, Pratyush Kshirsagar, Leo Hourvitz, Nick Demeuse, Kaitlyn Christensen, Aakanksha Parameshwar, Tingting Li, Mitil Jawale

Defensive Publications Series

The integration of a navigation software development kit (SDK) into a third-party application can present challenges related to the coupling of user interface (UI) element generation and layout logic, which may result in spatial conflicts and layout inflexibility. Systems and techniques are described for a delegate framework that can decouple UI generation from its placement. In this framework, a navigation SDK may manage the navigation state and, upon detecting a state change, can generate immutable state objects containing UI views or associated data. These objects may be passed to a delegate implemented by the host application, which can then be …

Adult-Onset Iga Vasculitis Initially Attributed To A Cutaneous Drug Reaction And Diverticulitis, Leila C. Tou, Catherine Grace P. Hobayan, Shane Devine, Sarah Koraym

Journal of Community Hospital Internal Medicine Perspectives

Immunoglobulin A vasculitis (IgAV), formerly Henoch–Schönlein purpura, is a small-vessel vasculitis characterized by palpable purpura, arthralgias, gastrointestinal involvement, and renal disease. Although IgAV is common in children, adult-onset disease is rare and may be associated with more severe manifestations, particularly renal involvement. In adults, IgAV may be difficult to recognize because of overlap with more common gastrointestinal, infectious, or medication-related conditions. We present a case of adult-onset IgAV initially attributed to presumed diverticulitis and later to a drug eruption following antibiotic exposure. This case highlights diagnostic pitfalls and the importance of early recognition and renal surveillance.

Journal of Community Hospital Internal Medicine Perspectives

Introduction: Occurrence of 2 (or more) Hodgkin's and non-Hodgkin's lymphoma concordantly or sequentially in a single patient is very rare.

Case: An 88-year-old Italian male with a history of mucosa-associated lymphoid tissue (MALT) lymphoma in remission and indolent follicular lymphoma under surveillance, presented with acute autoimmune hemolytic anemia (AIHA). While initially speculated to be secondary to follicular lymphoma relapse, stable mesenteric lymphadenopathy compared to prior CT abdomen/pelvis and smudge cells on peripheral smear prompted further evaluation. Peripheral blood flow cytometry indicated a mature B-cell neoplasm, which was confirmed to be chronic lymphocytic leukemia (CLL) with a bone marrow biopsy. Minimal …

Progressive Facial Swelling And Airway Symptoms Revealing A Deep Neck Abscess With Atypical Microbiology, Drew Knight, Hakam Sulaiman, Arash Bakian, Ilya Fonarov

Journal of Community Hospital Internal Medicine Perspectives

Deep neck abscesses have become less common in the antibiotic era; yet, they still pose major risks of morbidity and mortality if not addressed appropriately. Their proximity to the upper respiratory tract and mediastinal structures further exacerbates this risk. We present the case of a 56-year-old man with a medical history of type 2 diabetes mellitus, who exhibited a two-month history of recurrent left-sided facial edema, pain, and dysphagia. Computed tomography imaging confirmed a substantial fluid collection extending from the submandibular region into the mid-cervical area, from which aspiration yielded 110 mL of purulent material. Cultures indicated Cutibacterium acnes, …

Following initiation of rituximab, the patient experienced rapid improvement of the rash with no further disease progression

Corynebacterium Bacteremia In A High-Risk Host: A Diagnostic Dilemma Of Contamination Versus True Infective Endocarditis, Arman Manjikian, Christopher Aboujaoude, Nicole Rock, Don Pepito

Journal of Community Hospital Internal Medicine Perspectives

Corynebacterium species are often regarded as skin contaminants when isolated from clinical cultures. However, in select high-risk patients, these organisms can lead to significant infections, including infective endocarditis. We present the case of a 76-year-old woman with multiple comorbidities, including end stage renal disease (ESRD) on hemodialysis and an exposed tunneled central catheter, who developed Corynebacterium-associated native mitral valve endocarditis requiring surgical intervention. Despite prompt antimicrobial therapy and bioprosthetic valve replacement, her hospital course was complicated by heart block, empyema, and eventual cardiac arrest. This case highlights the importance of recognizing Corynebacterium as a potential pathogen in vulnerable patients …

Transesophageal echocardiography showed severe biventricular dysfunction with an ejection fraction of 15%, and cardiac MRI confirmed LVNC with a non-compacted to compacted ratio of 3.3. After successful ablation and normal coronary angiography, he was diagnosed with LVNC. This case highlights an unusual presentation of LVNC with typical atrial flutter and underscores the value of cardiac MRI …

Rasmussen’S Aneurysm: A Rare But Life-Threatening Complication Of Pulmonary Tuberculosis – A Case Report., Karan Puri

Journal of Community Hospital Internal Medicine Perspectives

Rasmussen’s aneurysm is a rare but potentially fatal complication of pulmonary tuberculosis. It represents a pseudoaneurysm of a pulmonary arterial branch caused by erosion of the arterial wall secondary to chronic inflammation within a tuberculosis cavity. Although uncommon, especially in non-endemic regions, rupture of this aneurysm can result in massive hemoptysis and carries a high mortality if not promptly recognized and managed. We report a case of a healthcare worker in the United States, a non-endemic region, who presented with massive, life-threatening hemoptysis. She was found to have active pulmonary tuberculosis. Computed tomography angiography demonstrated a 10-mm pseudoaneurysm arising from …

Rectal Dieulafoy Lesion With Severe Hematochezia In A Warfarin-Treated Patient, Carlos Elizondo Alatorre, Maria Gabriela Rubianes Guerrero, Julio C Valencia Manrique, Jennifer Harley

Journal of Community Hospital Internal Medicine Perspectives

Dieulafoy lesions (DLs) are rare vascular malformations in the gastrointestinal tract that often present with gastrointestinal bleeding, most commonly in the stomach. Rectal DLs are exceptionally rare, representing less than 2% of cases. Warfarin use increases the risk for bleeding and management represents a challenge. We present a case of a 60-year-old male on chronic warfarin therapy who presented with severe hematochezia due to a rectal DL, requiring more than one colonoscopy and prothrombin complex concentrate (PCC) administration. While guidelines recommend PCC over fresh frozen plasma (FFP), they acknowledge that this is based on very low certainty of evidence.

Steroid-Responsive Encephalopathy Associated With Autoimmune Thyroiditis: A Case Fulfilling Definite Graus Criteria, Stephanie Ammari, Nawras Ibrahim, Sravani Karuchola, Samir Ouais

Journal of Community Hospital Internal Medicine Perspectives

Steroid-responsive encephalopathy associated with autoimmune thyroiditis (SREAT), also known as Hashimoto encephalopathy, is a rare immune-mediated neurological syndrome with an incidence of 2.1 per 100,000 and a 4:1 female predominance. Neurological manifestations are independent of thyroid status, occurring in 30–40% of euthyroid patients, and include cognitive impairment, confusion, seizures, and psychiatric symptoms. Diagnosis is challenging in the elderly, where symptoms overlap with dementia or delirium, with only 51 reported cases in patients aged ≥65 years. We describe a 70-year-old woman with autoimmune hypothyroidism and levothyroxine nonadherence who presented with progressive weakness, melena, dyspnea, and altered mental status complicated by obstructive …

Piperacillin-Induced Immune Hemolytic Anemia Masked By Intestinal Failure-Associated Liver Disease: A Case Report With Three Serial Exposures, Stephanie Ammari, Nawras Ibrahim, Khalid Mahmood

Journal of Community Hospital Internal Medicine Perspectives

Background: Drug-induced immune hemolytic anemia (DIIHA) secondary to piperacillin has an estimated incidence of 0.01–0.10% [1,2]. In patients with intestinal failure-associated liver disease (IFALD), chronic conjugated hyperbilirubinemia obscures typical hemolytic markers [3,4].

Case Presentation: A 27-year-old woman with traumatic short bowel syndrome requiring total parenteral nutrition for 6 months, IFALD (baseline total bilirubin 2.5 mg/dL), and chronic kidney disease experienced three piperacillin-tazobactam exposures over two months. First exposure (12 days): hemolysis developed after drug discontinuation (primary sensitization). Second exposure: severe hemolysis occurred within 3 days (anamnestic response) with hemoglobin declining to 5.8 g/dL, undetectable haptoglobin, elevated LDH, reticulocytosis, and strongly …

Extranodal Marginal Zone Lymphoma Of The Breast In A Patient With Chronic Hepatitis C Infection: A Case Report, Ravneet K Dhanoa, Bipasha Goyal, Prateek Jain, Marilyn Baird-Howell, Mounika Gangireddy

Journal of Community Hospital Internal Medicine Perspectives

Primary breast lymphomas account for less than 1% of all non-Hodgkin lymphomas and 0.04–0.5% of all malignant breast neoplasms. We report a case of breast extranodal marginal zone lymphoma (EMZL) in a 60-year-old woman with chronic hepatitis C virus (HCV) infection. After comprehensive evaluation excluded other known etiologies, chronic HCV infection emerged as the most plausible contributing factor. Epidemiologic and biological evidence supports an association between HCV and B-cell non-Hodgkin lymphomas, particularly marginal zone lymphomas. Our case adds to the limited literature suggesting that HCV should be considered as a potential etiological factor in breast EMZL. We discuss the emerging …

A Tight Squeeze – Cardiac Tamponade In A Scleroderma Patient, Ifrah Nadeem, Charles E Geringer

Journal of Community Hospital Internal Medicine Perspectives

Systemic Sclerosis (SSc) is an autoimmune connective tissue disease marked by multiorgan fibrosis, including cutaneous involvement, and vasculopathy. Primary heart involvement in systemic sclerosis (SSc-pHI) includes heart failure, arrhythmia, pericarditis, pericardial effusion, valve disorders, and myocarditis. SSc-pHI remains a leading cause of mortality in this population. Pericardial effusion in SSc is usually associated with heart failure, pulmonary hypertension, and end-stage kidney disease. Cardiac tamponade is a rare initial presentation of SSc-pHI but carries a worse prognosis. Diagnosis is often challenging due to subclinical manifestations and requires advanced imaging modalities such as transthoracic echocardiography with tissue doppler and cardiac magnetic resonance …

A Case Of N-Methyl-D-Aspartate (Nmda) Autoimmune Encephalitis In A 34-Year-Old Man Thought To Have Schizophrenia, Riyad Amin, Michael Wilson, Morgan Koontz, Khawaja Omar

Journal of Community Hospital Internal Medicine Perspectives

Background: N-methyl-D-aspartate (NMDA) autoantibody encephalitis is a rare autoimmune condition affecting approximately 1.5 per million people per year [1]. It predominantly occurs in young women and is often associated with tumors, particularly teratomas [3]. The diagnosis is aided by testing cerebrospinal fluid (CSF) or serum for NMDA receptor antibodies along with careful evaluation of symptoms. Misdiagnosis is common, as its symptoms can mimic other more prevalent conditions, such as upper respiratory illnesses or psychiatric disorders like acute psychosis or schizophrenia.

Case Report: We present the case of a 34-year-old man who was initially incarcerated and subsequently developed decreased communication and …

Severe Multisystem Toxicity From Combination Ipilimumab And Nivolumab In Metastatic Melanoma: A Case Report, Bushra Amer, Sheetal Manerkar

Journal of Community Hospital Internal Medicine Perspectives

Immune checkpoint inhibitors (ICIs) have transformed cancer therapy by enhancing antitumor immunity. Despite their remarkable efficacy in malignancies, particularly metastatic melanomas, the use of ICIs have been linked to life-threatening immune-related adverse events (irAEs) affecting several organ systems. Combination therapy with ipilimumab and nivolumab increases both efficacy and the risk of severe irAEs. We report a rare case of metastatic melanoma treated with combination ipilimumab and nivolumab, complicated by multisystem irAEs. The patient developed hepatitis, cholangitis, ocular toxicity, and neurologic progression, highlighting the severity and complexity of immune-mediated toxicities following dual checkpoint blockade. This case underscores the potential for severe, …

Echocardiography In Stroke Management: Necessary Or Overused?, Nicole Ann Tesoro, Jasvin Kurundrayil Manha, Jerold Fleishman, Sumanth Bandaru

Journal of Community Hospital Internal Medicine Perspectives

Stroke remains a leading cause of morbidity and mortality worldwide, leading to the development of efficient and evidence-based management strategies. Echocardiography is a crucial diagnostic tool for identifying cardiac sources of embolism, particularly in cardioembolic and cryptogenic strokes, yet its routine use in all stroke patients remains controversial. While evidence-based guidelines recommend a patient-specific approach, rigid hospital quality metrics have incentivized widespread echocardiography, even in low-yield cases such as large artery atherosclerotic strokes. This disconnect raises concerns regarding cost-effectiveness, resource allocation, and potential over-testing, delaying discharges and prolonging hospital length of stay. A more tailored approach, focusing on guideline-driven indications, …
