Overview Testicular torsion is a urological emergency caused by twisting of the spermatic cord, leading to acute interruption of blood flow to the testis and rapid ischemia. It most commonly occurs in adolescents (peak 12–18 years) but can occur at any age, including neonates. The incidence is approximately 1 in 4,000 males under 25 years. Early […]

Overview Snapping Hip Syndrome (SHS) is characterized by an audible or palpable “snap” around the hip during motion; it may be painless or painful and can be unilateral or bilateral. Prevalence estimates suggest up to ~5–10% of the general population may experience snapping to some degree, with higher rates in dancers and athletes who work […]

Overview Prostatitis refers to a spectrum of conditions involving inflammation of the prostate gland, ranging from acute bacterial infection to chronic pelvic pain syndromes. It is a common urological condition affecting men of all ages, particularly those aged 30–50 years. The National Institutes of Health (NIH) classifies prostatitis into four categories: acute bacterial, chronic bacterial, chronic […]

Overview VEXAS syndrome is a late-onset, adult autoinflammatory disease caused by acquired somatic mutations in the UBA1 gene, leading to dysregulated innate immunity, systemic inflammation, and overlapping haematologic and rheumatologic manifestations.  VEXAS stands for Vacuoles, E1 enzyme, X-linked, Autoinflammatory, Somatic. It predominantly affects older males due to its X-linked nature and typically presents with refractory […]

Overview Osteonecrosis of the hip, usually referring to osteonecrosis of the femoral head (ONFH), is a progressive disorder caused by compromised subchondral blood supply leading to death of osteocytes and marrow elements, failed structural repair, subchondral fracture, femoral head collapse, and eventually secondary hip osteoarthritis.[1-4]  It most often affects younger to middle-aged adults, commonly between […]

Overview Amyloidosis is a disorder in which misfolded proteins aggregate into insoluble beta-pleated sheet fibrils and deposit extracellularly in tissues, leading to progressive organ dysfunction. It may be systemic or localized.  In current practice, the most clinically important systemic forms are AL (light-chain), AA (serum amyloid A), and ATTR (transthyretin; hereditary or wild-type). The phenotype […]
