Psoriatic arthritis (PsA) is a chronic inflammatory musculoskeletal disorder associated with psoriasis, a skin condition characterized by red, scaly patches. PsA is an autoimmune disease where the immune system mistakenly attacks healthy joint and skin tissues. It typically affects individuals between the ages of 30 and 50, though it may occur at any age. Symptoms
Psoriasis is a chronic, immune-mediated inflammatory skin disease characterized by hyperproliferation of keratinocytes and systemic inflammation. It manifests through red, scaly, and often itchy plaques on the skin. This condition affects more than 125 million people worldwide and can significantly impair quality of life due to its physical, emotional, and social impact. Pathophysiology of Psoriasis:
Psittacosis, also known as parrot fever or ornithosis, is a zoonotic infectious disease caused by the bacterium Chlamydia psittaci. It primarily affects individuals exposed to infected birds, particularly parrots, pigeons, and poultry. Though rare, psittacosis poses a serious public health concern due to its potential for severe respiratory illness and systemic complications in humans. Transmission
Pseudomonas aeruginosa is the most common and persistent pathogen found in the respiratory tracts of individuals with cystic fibrosis (CF). Its ability to form biofilms, adapt to the mucus-rich environment of CF lungs, and develop multidrug resistance makes it a formidable challenge in long-term disease management. Chronic colonization often begins in adolescence and is associated
Pseudomonas aeruginosa urinary tract infections (UTIs) represent a challenging and often persistent form of gram-negative bacteriuria, particularly prevalent in hospital settings. Known for its resistance to multiple antibiotic classes and ability to form resilient biofilms, P. aeruginosa UTIs are primarily associated with catheter use and immunocompromised states, requiring prompt identification and targeted management. Epidemiology and
Pseudomonas aeruginosa septicemia is a rapidly progressing and often fatal bloodstream infection caused by a gram-negative, opportunistic pathogen. Known for its robust resistance mechanisms and nosocomial prevalence, this bacterium presents a formidable challenge in critical care settings, especially among immunocompromised individuals, burn victims, and patients with prolonged hospitalization or invasive devices. Epidemiology and High-Risk Patient
Pseudomonas aeruginosa pneumonia is a severe lower respiratory tract infection caused by a highly virulent gram-negative bacterium. Predominantly observed in healthcare settings, it is a major cause of hospital-acquired pneumonia (HAP) and ventilator-associated pneumonia (VAP), particularly in immunocompromised or critically ill patients. Its intrinsic resistance mechanisms, ability to form biofilms, and adaptability make it one
Pseudomonas aeruginosa peritonitis represents a severe and potentially life-threatening intra-abdominal infection, particularly prevalent in patients undergoing peritoneal dialysis (PD). Due to its intrinsic resistance mechanisms and capacity to form biofilms, this gram-negative pathogen poses substantial treatment hurdles and increases the risk of technique failure, catheter loss, and transition to hemodialysis. Epidemiology and Risk Factors While
Pseudomonas aeruginosa, a gram-negative opportunistic pathogen, is a leading cause of osteomyelitis, especially in immunocompromised patients or following trauma and surgical procedures. Known for its biofilm-forming capacity and antibiotic resistance, this bacterium complicates bone infections and presents significant therapeutic challenges. Pathogenesis and Infection Mechanisms Pseudomonas aeruginosa initiates osteomyelitis through hematogenous spread, contiguous infection from nearby
Pseudomonas aeruginosa meningitis represents a severe and potentially fatal central nervous system (CNS) infection, predominantly observed in hospital settings, especially following neurosurgical procedures or head trauma. As a multidrug-resistant, gram-negative bacillus, P. aeruginosa poses considerable diagnostic and therapeutic challenges.
