Comparative Efficacy of Hypertension Management Strategies.

Hypertension (HTN) is a major cardiovascular risk factor and a significant contributor to disease burden in the United States. Despite therapeutic advances, gaps remain between clinical trials and practice. This study aims to bridge those gaps by evaluating antihypertensive strategies.

Xanthogranulomatous Pyelonephritis: A pooled quantitative analysis of published cases.

Xanthogranulomatous Pyelonephritis (XGP) is a serious and rare inflammatory disease of unknown etiology. This systematic review analyzes XGP cases. We performed a literature search for "Pyelonephritis, Xanthogranulomatous.

COVID-19 Exposure Unmasking Systemic Amyloidosis With Hepatic Predominance.

Amyloidosis is characterized by depositing insoluble fibrillar proteins that misfold into beta-pleated sheets. This phenomenon occurs on a systemic or local level and may interfere with the function of various organs, including the heart, kidneys, and liver. Among those presenting with amyloidosis, hepatic, gastrointestinal, renal, cardiac, vitreous, and immunological involvement may occur.

Fulminant Anti-Neutrophil Cytoplasmic Antibody-Associated Vasculitis After 10 Years of Hydralazine Use.

Vasculitis, by definition, causes changes in the walls of blood vessels, including thickening, weakening, narrowing, and scarring, leading to inflammation and necrosis of the blood vessel walls. Small-vessel vasculitis is commonly associated with anti-neutrophil cytoplasmic antibodies (ANCA), which activate cytokine-primed neutrophils and monocytes that express ANCA antigens proteinase 3 (PR3) and myeloperoxidase (MPO) on their surface. The continuous injury and inflammation of these small vessels characterized by circulating immune complexes and antinuclear antibodies result in clinical features standard in all types of vasculitis.

Hemi-central retinal vein occlusion as a rare manifestation of the hypercoagulable state in COVID-19.

To date, COVID-19 has no definite effective targeted therapy, and management is primarily supportive. Central retinal vein occlusion (CRVO) is frequently caused by systemic risk factors posing hypercoagulable states. In April 2020, a female patient with a history of hypertension, diabetes mellitus and chronic kidney disease presented with 2 days of loose, watery stools, nasal congestion and severe lethargy.

"Two for One", Novel Dual Left Anterior Descending Artery (LAD) Variant: Type XIII.

Dual left anterior descending artery (LAD) is a rare phenomenon that occurs in less than one percent of the population. To date, 12 variants have been identified. Proper identification of coronary vessels is crucial in emergent situations that require prompt action, such as percutaneous coronary intervention (PCI).
