Classification of Illness01:17

Classification of Illness

7.6K
The meaning of illness is individualized to each person who experiences an alteration in health. In contrast, disease is a medical term indicating a pathological change in the structure and function of the body or mind. It is a condition that has specific symptoms and boundaries.
An illness is a response to a disease in which the person's level of functioning is changed compared with a previous level. The general classification of illness includes acute and chronic.
Acute illness is severe...

Stages of Infection

56.9K
Stages of infection describe what happens to a susceptible host once a pathogen invades the human body. The stages of infection are incubation, prodromal, illness, stage of decline, and convalescence. The incubation stage is the period from exposure to a pathogen until symptoms start. The infected person is unaware of impending illness as the pathogens grow and multiply within the body. The duration may vary depending on the type of infection. The incubation period of measles averages ten to...

Drugs Affecting GI Tract Motility: Antimicrobials as Antidiarrheal Agents

157
Acute diarrhea, a common gastrointestinal disturbance, is characterized by the rapid evacuation of fluid stools, leading to an excessive weight in fluid. This condition typically arises from disorders affecting intestinal water and electrolyte transport. It can be triggered by an increased osmotic load within the intestine, excessive secretion of electrolytes and water, mucosal exudation of protein and fluid, or altered intestinal motility. The primary risks of acute diarrhea are dehydration...

Transmission-based Precautions I: Contact, Enteric, and Droplets

3.7K
Transmission-based precautions are for patients known to be infected or suspected to be infected or colonized with organisms that pose a significant risk to others. Some transmission-based precautions include contact, enteric, and droplet.
Contact Precautions:
Contact precautions are the measures taken to prevent the transmission of infectious agents, especially epidemiologically important microorganisms such as MRSA or influenza, primarily transmitted through direct or indirect contact with an...

Pulmonary Tuberculosis I01:29

Pulmonary Tuberculosis I

266
Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
Mode of...

Area of Science:

  • Critical Care Medicine
  • Infectious Diseases
  • Travel Medicine

Background:

  • Critical illness in returning travelers poses diagnostic and management challenges.
  • Elderly travelers, those with comorbidities, and immunosuppression increase complexity.
  • Changing global disease patterns necessitate consideration of a broad differential diagnosis.

Observation:

  • A 70-year-old man with recent travel to rural Iraq presented with fever, rigors, and multiorgan failure.
  • Extensive diagnostic tests and multi-organ support with antibiotics were initiated.
  • Challenges included history acquisition, broad differentials, specialized investigations, and infection transmission risks.

Findings:

  • Unusual infections, venous thromboembolic disease, and antimicrobial resistance are key considerations.
  • Non-infectious causes of fever and critical illness must also be evaluated.
  • Specialist support, like the UK's Imported Fever Service, is vital for High Consequence Infectious Diseases.

Implications:

  • A multidisciplinary team approach is essential for optimal patient care.
  • Thorough information gathering, repeated clinical review, and judicious investigations are paramount.
  • Robust infection control measures are critical for protecting patients and staff.
