Nationwide Analysis of Adult-Onset Still Disease With and Without Hemophagocytic Lymphohistiocytosis.

Introduction: Adult-onset Still disease (AOSD) is a rare inflammatory condition with a monophasic, intermittent, or chronic clinical course, and a subset may experience life-threatening complications such as hemophagocytic lymphohistiocytosis (HLH). This study aims to characterize concurrent AOSD and HLH and identify variables independently associated with in-hospital death.

Methods: We performed a medical records review of AOSD with and without HLH from the 2016-2019 National Inpatient Sample database.

Acetaminophen overdose: analysis of 2018 US nationwide emergency database.

Introduction: Recognized risk factors for acetaminophen overdose include alcohol, opioids, and mood disorders. The aim of this study is to assess additional risk factors for acetaminophen overdose evaluated in the emergency department (ED).

Methods: A retrospective study was performed using the 2018 US Nationwide Emergency Department Sample (NEDS).

Nationwide analysis of adult hospitalizations with hematologic malignancies and systemic sclerosis.

Introduction Systemic sclerosis (SSc) is a connective tissue disease with multi-system involvement and it has an increased risk of developing hematologic malignancies. This study aims to report the association between hematologic malignancies with SSc and to characterize in-hospital demographics and outcomes in patients with hematologic malignancies with and without SSc. Methods We performed a retrospective review of pooled data from the National Inpatient Sample (NIS) database from 2016 to 2020.

Nationwide analysis of neuromyelitis optica in systemic lupus erythematosus and Sjogren's syndrome.

Objective: Neuromyelitis optica (NMO), also known as Devic's disease, is a rare inflammatory demyelinating disorder causing myelitis and optic neuritis. While there have been reports of systemic lupus erythematosus (SLE) and primary Sjogren's syndrome (SS) occurring with NMO, a formal association is not established. We aimed to investigate the occurrence of NMO in SLE and SS patients and study the clinical characteristics and outcomes of NMO and SLE/SS hospitalizations utilizing the national inpatient sample (NIS) database.

Familial Association of Granulomatosis With Polyangiitis: A Case-Based Review of Literature.

Anti-neutrophil cytoplasm antibody (ANCA)-associated vasculitis (AAV) is a class of small vessel vasculitis that includes granulomatosis with polyangiitis (GPA), eosinophilic GPA (EGPA), and microscopic polyangiitis (MPA). Despite extensive research, the mechanisms behind AAV etiology remain obscure. The genetics of AAV is a complex area of investigation because of the rarity of familial cases.

IgG4-related disease and isolated retroperitoneal fibrosis: A narrative review.

Retroperitoneal fibrosis (RPF) can occur due to many etiologies and is categorized into idiopathic and secondary. Etiologies of secondary RPF include medications, autoimmune disease, malignancy, and IgG4-related disease (IgG4-RD). Although IgG4-RD usually involves multiple systems synchronically including the pancreas, aorta, and kidneys, it can present with isolated RPF without involvement of other organ systems.

Rare Presentation of Disseminated Gout Nodulosis and Chronic Inflammatory Arthritis.

Background: Gout is an inflammatory arthritis caused by monosodium urate (MSU) deposition. Acute gout is a dramatic painful swelling of the joint; however, MSU can deposit in other tissues as well, including skin, gastrointestinal tract, and bones over time. Disseminated tophi in the skin are a rare presentation of gout known as gout nodulosis.

Hemorrhagic Cardiac Tamponade as a Complication of Limited Cutaneous Systemic Sclerosis.

Cardiac tamponade is an uncommon complication of systemic sclerosis (SSc) with a high mortality rate. Here, we report a case of a 58-year-old patient with limited cutaneous systemic sclerosis (lcSSc), gastroesophageal reflux disease (GERD), diabetes mellitus, pulmonary hypertension (PHTN), and COVID-19 infection, which occurred one month ago, presenting with a large hemorrhagic pericardial effusion and early cardiac tamponade. The patient had an acute onset of progressive dyspnea and anasarca.

Reasons for Hospitalization and All-Cause Mortality for Adults with Sarcoidosis.

Purpose: Sarcoidosis is a multisystem immune disease with a high rate of hospitalization. There is a paucity of large population-based studies on sarcoid inpatients. We aimed to examine the reasons for hospitalizations and mortality of adult sarcoid patients utilizing the National Inpatient Sample (NIS) database.

Angioedema as a Rare Presentation of Systemic Lupus Erythematosus.

Angioedema (AE) is an immune-mediated tissue swelling that can be life-threatening if it compromises the airway. This makes prompt diagnosis and management of the condition excruciatingly important. It can be hereditary or associated with infections, malignancies, and autoimmune diseases.

Crystalline Nephropathy With High-Dose Methotrexate in a Patient With Primary CNS Lymphoma: A Case Report.

Methotrexate (MTX) is a folate antimetabolite used in the treatment of several malignancies and rheumatologic diseases. It is metabolized in the liver and excreted via the kidneys. Several adverse effects of MTX have been noted, including bone marrow suppression, mucositis, and hepatic and renal dysfunction.
