Changes in Skin Color: Clinical Perspectives01:14

Changes in Skin Color: Clinical Perspectives

The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.
Albinism
Albinism is a genetic disorder that affects (completely or partially) the coloring of skin, hair, and eyes. The defect is primarily...
Pulmonary Tuberculosis III01:31

Pulmonary Tuberculosis III

Tuberculosis (TB) is a contagious infection primarily affecting the lung parenchyma but which can also affect other body parts. TB can be classified based on disease development, presentation, and the affected anatomical site.
The first classification is based on the development of the disease, and it includes the following categories:
Acute Respiratory Failure-IV01:23

Acute Respiratory Failure-IV

Respiratory failure can manifest suddenly or gradually, characterized by a rapid decline in PaO2 and a rapid rise in PaCO2. This situation indicates a severe respiratory problem that may quickly become a life-threatening emergency. One of the early signs of hypoxemic Acute Respiratory Failure (ARF) is a change in mental status due to the brain's sensitivity to oxygen levels and changes in acid-base balance. Symptoms such as restlessness, confusion, and agitation suggest inadequate oxygen...

Positive Symptoms of Schizophrenia: Hallucinations and Delusions

Schizophrenia is a complex mental health disorder that can manifest with various positive symptoms, including thought, movement, and behavior disorders. These symptoms significantly disrupt cognitive and motor functions, leading to profound effects on an individual's ability to engage with the world.
Thought Disorders
Disorganized and unusual thought processes mark thought disorders in schizophrenia. One key feature is disorganized speech, where an individual's conversation includes loosely...
Alterations in Muscle Tone lll01:11

Alterations in Muscle Tone lll

Rigidity and myotonia are distinct abnormalities of muscle tone that affect resistance and relaxation during movement. Although both involve altered muscle contraction, they arise from different neurological and muscular mechanisms.CharacteristicsRigidity is characterized by uniform resistance to passive movement across the entire range, independent of speed, affecting flexors and extensors equally. It may appear as lead-pipe rigidity (smooth, constant resistance) or cogwheel rigidity...

Summary

Postural abnormalities like camptocormia affect Parkinson's disease (PD) patients. Understanding their multifactorial causes and improving treatments requires further research with consistent methods.

Area of Science:

  • Neurology
  • Movement Disorders
  • Musculoskeletal System

Background:

  • Postural abnormalities affect 20-30% of Parkinson's disease (PD) patients.
  • Common types include camptocormia, Pisa syndrome, and dropped head syndrome.
  • Mechanisms and risk factors (disease duration, age, medication) are poorly understood.

Purpose of the Study:

  • To review the current understanding of postural abnormalities in Parkinson's disease.
  • To highlight diagnostic challenges and contributing factors.
  • To summarize existing and needed therapeutic interventions.

Main Methods:

  • Literature review and synthesis of existing research on PD postural abnormalities.
  • Discussion of diagnostic criteria and measurement techniques.

  • Analysis of proposed central and peripheral contributing factors.

    • Main Results:

    • Postural abnormalities in PD are multifactorial, involving central and peripheral mechanisms.
    • Diagnosis is challenging due to varied definitions and methods.
    • Current treatments offer unpredictable and often temporary relief.

    Conclusions:

    • Further large-scale research with standardized methods is crucial.
    • Neurophysiological assessments are needed to elucidate mechanisms.
    • Development of effective, evidence-based interventions for PD postural disorders is a priority.
