Stimulants01:29

Stimulants

172
Stimulants are substances that enhance neural activity and elevate dopamine levels in the brain, leading to their highly addictive nature. These drugs include cocaine, amphetamines, MDMA, caffeine, and nicotine, each with distinct mechanisms of action and varied health implications.
Cocaine can be administered via snorting, injection, or smoking. It primarily functions by blocking the reuptake of dopamine, resulting in a euphoric high characterized by an intense sensation of happiness and...

Physical Assessment of the Respiratory Tract I: Health History

167
Physical assessment of the respiratory tract is critical to patient care. It allows healthcare professionals to identify and manage various respiratory conditions. The process involves a combination of subjective and objective data collection.
Subjective Data
Subjective data provides vital information about the patient's health history and symptoms. This data is typically collected through interviews in which patients describe their experiences, symptoms, and concerns.

Factors Affecting Illness01:18

Factors Affecting Illness

4.2K
When a person's physical, emotional, intellectual, social development or spiritual functioning is compromised, this deviation from a healthy normal state is called illness. Illness creates stress that in turn harms individuals. Irritation, anger, denial, hopelessness, and fear are behavioral and emotional changes an individual experiences in the phases of illness. A variety of factors influence a person's health and well-being.
For instance, risk factors are connected to illness,...

Summary

Vaping-associated illness (VAI) can affect multiple organ systems, not just the lungs. Recognizing systemic symptoms like fever and gastrointestinal issues is crucial for diagnosing this condition.

Area of Science:

  • Pulmonology
  • Toxicology
  • Internal Medicine

Background:

  • Reports of vaping-associated illness (VAI), also known as e-cigarette and vaping product associated lung injury (EVALI), emerged in 2019.
  • The precise mechanism of injury in VAI remains unclear.
  • VAI presents with respiratory distress and involvement of other organ systems.

Purpose of the Study:

  • To reexamine the clinical characteristics of patients diagnosed with VAI.
  • To propose that lung injury may be part of a larger systemic illness rather than the primary dysfunction.

Main Methods:

  • Retrospective chart review of patients presenting with VAI at a single hospital.
  • Analysis of clinical presentation, including symptoms and organ system involvement.

Main Results:

  • Fourteen patients aged 15-33 years were identified.
  • A wide range of clinical severity was observed.
  • Symptoms included respiratory (64%), gastrointestinal (57%), fever (78%), neurological (15%), and constitutional (50%). Notably, 35% presented without respiratory symptoms.

Conclusions:

  • Vaping-associated illness involves multiple organ systems beyond the lungs.
  • Understanding the systemic involvement is key to elucidating the disease's pathophysiology.
  • Clinicians should consider a broad differential diagnosis for VAI, including non-respiratory symptoms like abdominal pain, headache, and fever.
