Summary
Severe metal fume fever from galvanized steel exposure can cause serious lung damage. Early steroid treatment may significantly reduce illness severity and duration, as seen in two case studies.
Area of Science:
- Occupational Medicine
- Toxicology
- Pulmonary Medicine
Background:
- Metal fume fever (MFF) is typically a self-limited, influenza-like illness.
- Severe and prolonged MFF is uncommon, even with significant metal fume exposure.
Observation:
- Two cases of severe MFF occurred in males dismantling galvanized steel with an acetylene torch in a poorly ventilated space.
- Both patients presented with diffuse alveolar damage on high-resolution computed tomography (HRCT) scans.
- Symptom severity and duration differed significantly between the two patients.
Findings:
- The 29-year-old patient, treated with steroids within 1 day of exposure, experienced a milder illness.
- The 51-year-old patient, treated 3 days post-exposure, had a more protracted and severe course.
- HRCT confirmed diffuse alveolar damage in both individuals, indicating significant lung injury.
Implications:
- This report highlights the potential for severe lung injury from MFF, contrary to its usual benign presentation.
- Prompt corticosteroid administration may be a crucial therapeutic intervention for severe MFF.
- Occupational safety measures, including adequate ventilation, are critical when working with galvanized steel.

01:23Chronic Obstructive Pulmonary Disease II: Emphysema
Emphysema, a major phenotype of chronic obstructive pulmonary disease (COPD), is characterized by irreversible destruction of alveolar walls and permanent enlargement of distal airspaces. Unlike chronic bronchitis, which primarily affects the airways, emphysema predominantly involves the lung parenchyma, where structural damage leads to airflow limitation.PathophysiologyIt most commonly results from prolonged exposure to cigarette smoke and other toxic gases, particularly cigarette smoke.
01:10Atelectasis II: Pathophysiology
Atelectasis develops when alveoli lose their air and collapse inward. Because lung tissue is naturally elastic, these air sacs shrink rather than remaining open. Collapsed alveoli are no longer ventilated, reducing their role in gas exchange. Blood flow may continue in these regions, creating a ventilation–perfusion mismatch. Clinical findings include decreased breath sounds, dullness to percussion, reduced chest expansion, and decreased tactile fremitus as sound transmission through collapsed...
01:20Chronic Obstructive Pulmonary Disease-II: Pathophysiology
Chronic Obstructive Pulmonary Disease (COPD) pathophysiology is intricate and multifaceted, involving a complex interplay of physiological processes. Understanding these mechanisms is crucial for effectively managing and treating COPD. Here is an in-depth look at the critical elements in the pathophysiology of COPD:
Chronic Inflammation

01:21Acute Respiratory Failure-II
Type I Respiratory Failure, or hypoxemic respiratory failure, occurs when the partial pressure of oxygen (PaO2) in arterial blood falls below 60 mmHg while breathing room air without a corresponding increase in arterial carbon dioxide levels (PaCO2). This condition highlights a significant impairment in the lungs' capacity to oxygenate the blood.
The underlying physiological abnormalities that contribute to hypoxemic respiratory failure include:

01:24Chronic Obstructive Pulmonary Disease III: Chronic Bronchitis Features
Chronic bronchitis is a key phenotype of chronic obstructive pulmonary disease (COPD), characterized by airway-centered inflammation and mucus overproduction. It develops from long-term exposure to harmful particles or gases, most commonly cigarette smoke, which triggers a persistent inflammatory response.Cellular and Structural ChangesInflammation initially affects the large bronchi and later the smaller airways, with infiltration by immune cells, including neutrophils, macrophages, and...
01:25Inhalation Anthrax
Anthrax is a zoonotic disease caused by Bacillus anthracis, a Gram-positive, spore-forming bacterium. It primarily affects herbivorous animals but can be transmitted to humans through skin contact, ingestion, or inhalation of spores.Cutaneous anthrax, the most common form, typically results from direct contact with bacterial spores through skin abrasions and is generally less severe. Gastrointestinal anthrax results from eating undercooked or contaminated meat. It affects the mouth, throat, or...
