Pulmonary Actinomycosis

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

Psychotic Disorder

A psychotic disorder is a serious mental health condition that affects an individual’s perception of reality, leading to significant disruptions in thought processes, emotions, and behaviors. Individuals with psychotic disorders often experience hallucinations, delusions, and disorganized thinking, which can severely impact their ability to function in daily life. Understanding the different types, causes, symptoms, and

Psychosis Associated with Parkinson’s Disease

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

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

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

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

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 Respiratory Tract Infection in Cystic Fibrosis

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 Infection

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

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.
