Acute pulmonary disease caused by phenytoin
Annals of Internal Medicine
|October 1, 1981
Summary
Phenytoin sodium can cause acute pulmonary disease, a hypersensitivity reaction. Symptoms include fever, shortness of breath, and lung infiltrates, which are reversible with drug cessation and steroid treatment.
Area of Science:
- Pulmonology
- Toxicology
- Pharmacology
Background:
- Phenytoin sodium is an anticonvulsant medication with known potential adverse effects.
- Hypersensitivity reactions can manifest in various organ systems, including the lungs.
Observation:
- Acute pulmonary disease, characterized by fever, dyspnea, hypoxemia, and bilateral infiltrates, can be a manifestation of phenytoin-induced hypersensitivity vasculitis.
- The underlying pathology involves interstitial pneumonitis.
Findings:
- Cessation of phenytoin sodium therapy is crucial for managing this pulmonary complication.
- Treatment with corticosteroids demonstrates efficacy in reversing the interstitial pneumonitis.
Implications:
- Early recognition of phenytoin-induced lung disease is vital for prompt intervention and favorable outcomes.
- This highlights the importance of considering drug-induced lung injury in patients presenting with acute respiratory symptoms.
- Clinicians should be aware of the potential for pulmonary toxicity associated with phenytoin sodium use.

906
Pulmonary hypertension (PH) is a severe health condition in which the mean pulmonary arterial pressure increases to 25 mmHg or more, even when the body is at rest. This high pressure in the blood vessels that transport blood from the heart to the lungs can cause various symptoms, including shortness of breath, can lead to right heart failure, and significantly affect the overall quality of life.
There are various classifications for PH, each relating to different underlying causes and also...

Pneumonia is an acute respiratory infection that targets the lungs, specifically the alveoli. These tiny air sacs, essential for oxygen exchange, become engorged with pus and fluid, severely hindering breathing, decreasing oxygen absorption, and causing significant pain and discomfort during respiration.
Risk Factors
Various factors influence the likelihood of developing pneumonia. Age plays a crucial role, with infants, children under two, and individuals over 65 at increased risk due to their...

1.7K
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.

Tuberculosis, or TB, is a bacterial infectious disease caused by Mycobacterium tuberculosis. While its primary impact is on the lungs, leading to pulmonary tuberculosis, it can also affect various other organs, a condition referred to as extrapulmonary tuberculosis.
Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...

Medical management of tuberculosis (TB) patients involves a comprehensive approach that includes diagnosis, treatment, and monitoring. The specific strategies can vary depending on the type of tuberculosis (latent or active), the patient's overall health status, and other considerations.
Latent tuberculosis infection occurs when TB bacteria are present in a person's body, but are not causing illness or symptoms. It is not contagious, and preventive treatment is crucial to avoid the...

01:29Pneumonia I: Introduction

Pneumonia is an infection of the lower respiratory tract that leads to inflammation of the lung parenchyma, often resulting in the accumulation of inflammatory exudate in the alveoli and airways. Unlike the watery, low-protein fluid exudate in pulmonary edema, the exudate in this case is a thick fluid rich in immune cells, proteins, and debris produced during infection and inflammation.This impairs gas exchange and can lead to consolidation of lung tissue. The infection may be caused by a...
