Summary
Wilson
Area of Science:
- Neurology
- Hepatology
- Pathology
Background:
- Wilson's disease (WD) is a genetic disorder affecting copper metabolism, commonly seen in South India.
- Limited research exists on the pathomorphological features of Wilson's disease in this population.
Purpose of the Study:
- To detail the autopsy-based pathomorphological features of eight Wilson's disease cases.
- To differentiate between neurological and hepatic forms of Wilson's disease.
Main Methods:
- Autopsy examination of brain, liver, and visceral organs from eight Wilson's disease patients.
- Histopathological analysis to identify specific cellular and tissue changes.
Main Results:
- Neurological WD cases showed central pontine myelinolysis, subcortical white matter cavitations, putaminal softening, and ventricular dilatation.
- Opalski cells and pontine myelinolysis were specific to the neurological form.
- All cases exhibited liver abnormalities, including cirrhosis, steatosis, and chronic active hepatitis.
- Lenticular nucleus involvement was not universal, challenging the 'hepatolenticular degeneration' description.
Conclusions:
- Pathomorphological findings aid in distinguishing neurological and hepatic Wilson's disease.
- Specific brain lesions like pontine myelinolysis are key indicators of neurological WD.
- Wilson's disease pathology extends beyond the liver and lenticular nucleus.

01:23Alzheimer Disease ll: Pathophysiology
Alzheimer disease involves structural changes in the brain that begin long before symptoms appear. The most distinctive features are extracellular neuritic plaques and intracellular neurofibrillary tangles.Neuritic plaques form in the cerebral cortex and around blood vessels. These plaques contain a dense core of beta-amyloid (Aβ)—a toxic protein fragment that clumps outside neurons. The core is surrounded by damaged neuronal extensions, as well as reactive astrocytes and microglia. Abnormal...
01:22Lysosomal Hydrolases
Lysosomes are the site for the degradation of macromolecules and biological polymers released during membrane trafficking events such as secretory, endocytic, autophagic, and phagocytic pathways. The membrane-enclosed area of the lysosome, called the lumen, contains hydrolytic enzymes active in an acidic environment. These acid hydrolases are functional at a pH between 4.5 and 5 and are involved in cellular processes such as cell signaling, energy metabolism, restoration of the plasma membrane,...
01:21Huntington Disease l: Introduction
Huntington disease or HD is a progressive, fatal neurodegenerative disorder inherited in an autosomal dominant pattern.PathophysiologyIt is caused by expansion of the CAG trinucleotide repeat in the HTT gene on chromosome 4 (4p16.3), producing an abnormal huntingtin protein with an expanded polyglutamine tract. This misfolded protein disrupts cellular function, leading to neuronal death. Normal alleles have ≤26 repeats, 27–35 are intermediate (risk of expansion), 36–39 show reduced penetrance,...
01:21Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation
Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...
