Pulmonary actinomycosis is a rare but serious bacterial infection that affects the lungs, primarily caused by Actinomyces species. It is a type of actinomycosis, a condition that typically manifests in the cervicofacial region, but can also affect the chest, abdomen, and pelvis. This lung infection often presents with symptoms resembling more common respiratory illnesses, making
Psychosis in Parkinson’s disease (PD) refers to the occurrence of hallucinations and delusions in patients diagnosed with Parkinson’s. This condition represents one of the most challenging non-motor symptoms associated with the disease, significantly impacting the patient’s quality of life and complicating their treatment regimen. Approximately 20% to 40% of individuals with Parkinson’s experience psychotic symptoms
Psychosis associated with Alzheimer’s disease (AD) represents a subset of neuropsychiatric symptoms characterized by delusions and hallucinations. These symptoms are not mere byproducts of memory loss but core clinical manifestations affecting 30% to 50% of individuals diagnosed with AD. Psychosis not only exacerbates cognitive decline but also accelerates functional deterioration, increases caregiver burden, and often
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 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
Complicated appendicitis—marked by perforation, abscess formation, or gangrene—poses a heightened risk for infection with multidrug-resistant organisms such as Pseudomonas aeruginosa. Recognized for its adaptability and intrinsic resistance mechanisms, this gram-negative bacterium significantly influences therapeutic strategies, recovery time, and prognosis. Pathogenesis of Pseudomonas Aeruginosa in Appendiceal Infections P. aeruginosa is not a primary colonizer of the
Pseudomonas aeruginosa bronchitis represents a serious respiratory tract infection primarily affecting individuals with underlying pulmonary diseases, immunosuppression, or structural lung abnormalities. This opportunistic pathogen poses significant clinical challenges due to its high antibiotic resistance and ability to form biofilms in the respiratory mucosa. Pathophysiology of Pseudomonas Aeruginosa in Bronchial Infections P. aeruginosa is a gram-negative,
