Abnormal Proliferation02:23

Abnormal Proliferation

5.1K
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...

Respiratory System Abnormal Finding I: Inspection and Percussion

803
Respiratory system abnormalities are a significant concern in healthcare due to their potential to indicate underlying severe conditions like Chronic Obstructive Pulmonary Disease (COPD), asthma, and pneumonia. These abnormalities can often be detected through physical examination methods like inspection and percussion.
Inspection Findings
During an inspection, several findings may suggest the presence of respiratory distress or disease. Pursed-lip breathing, where exhalation is slowed by...

Cardiovascular System Abnormal Findings II: Auscultation

587
Auscultation, an essential part of a heart examination, is done using a stethoscope. It provides crucial information about heart function and possible heart problems. Due to heart problems, abnormal sounds can be heard during systole or diastole. These sounds include S3 and S4 gallops, opening snaps, systolic clicks, and murmurs.

Respiratory System Abnormal Finding II: Palpation and Auscultation

1.4K
In assessing respiratory abnormalities, palpation and auscultation are critical tools for detecting and interpreting various pathophysiological changes. These techniques provide insight into underlying disorders by evaluating tactile sensations and sounds produced by the respiratory system.
Palpation Findings
During a respiratory assessment, palpation can reveal several vital abnormalities:

Types of Hormones02:13

Types of Hormones

83.3K
Hormones can be classified into three main types based on their chemical structures: steroids, peptides, and amines. Their actions are mediated by the specific receptors they bind to on target cells.

Area of Science:

  • Neuroscience and Sleep Medicine
  • Clinical Psychology
  • Occupational Health

Context:

  • Abnormal daytime drowsiness affects 3-4% of the population in industrialized nations.
  • This condition significantly impairs the ability to perform in safety-critical occupations.
  • Existing diagnostic tools include the Multiple Sleep Latency Test and vigilance tests.

Purpose:

  • To define abnormal daytime drowsiness based on subjective, objective, and objective test criteria.
  • To highlight the importance of early diagnosis and effective treatment for affected individuals.
  • To explore neurophysiological underpinnings and clinical typologies of excessive daytime sleepiness.

Summary:

  • Daytime drowsiness is characterized by persistent tiredness, observed sleep attacks, and objective findings in sleep tests.
  • Neurophysiological differentiation includes REM/non-REM drowsiness and arousal system dysfunctions (hypo/hyperfunction).
  • Clinical typologies encompass permanent somnolence and narcoleptic-type imperative sleep attacks.

Impact:

  • Effective treatments can often eliminate symptoms, restoring work capacity and improving patient well-being.
  • Understanding the different forms of drowsiness aids in targeted therapeutic interventions.
  • Early medical intervention is essential for managing this prevalent condition and its occupational consequences.
