Inhaled Corticosteroids and Bronchodilators: Administration

In a regimen of inhaled corticosteroids and bronchodilators, bronchodilators should be administered first. Steroids relieve symptoms but do not treat the inflammation.

Difference Between Bronchodilators and Steroidal Anti-Inflammatories

Bronchodilators act by dilating and opening the bronchus. Short-acting medications are used for immediate relief, while long-acting forms are used with scheduled corticosteroids.

Anti-inflammatories eliminate or alleviate inflammation of the bronchi. Steroids are the most widely used anti-inflammatories.

Health Education for Patients on Inhaled Glucocorticoids

• If using a combined regimen of bronchodilators and corticosteroids, inhale the bronchodilator first.

Pancreatitis: Inflammation, Causes, and Care

Acute Pancreatitis

Acute pancreatitis is a sudden inflammation of the pancreas that can range from mild to life-threatening, though it usually subsides. Gallstones and alcohol abuse are responsible for approximately 80% of cases. It is more frequently caused by gallstones or obstruction of the pancreatic duct by a gallstone lodged in the sphincter of Oddi, interrupting the flow of pancreatic juice. However, if the obstruction persists, activated enzymes accumulate in the pancreas and begin to digest its cells, causing severe inflammation.

Symptoms of Acute Pancreatitis

• A belt-like, intense abdominal pain in the upper abdomen, typically below the sternum. When pancreatitis is caused by gallstones, the

Patents and Health Differences Between Countries

A patent is a set of exclusive rights guaranteed by a government or an authority to the inventor of a new product or a new manufacturing method, which could be exploited industrially for the benefit of the inventor and for a time-bound implementation.

Pharmaceutical patents relate to new medicinal products or production methods from pharmaceutical research.

The most commonly used method to reduce public pharmaceutical expenditure is the use of generic drugs, i.e., drugs that are developed after the brand-name drug's patent has expired. These are sold without a trademark, with a similar active ingredient, pharmaceutical form, composition, and equivalence to the reference brand drug.

Vitamins and Minerals

Soluble Vitamins

Vitamin C: Protects, regulates, and facilitates chemical processes of other enzymes. Its main function is the formation of collagen, facilitates the absorption of iron, protects vitamin A and E from oxidation, and regulates cholesterol metabolism. Sources: green vegetables, citrus fruits, tomatoes. Deficiency: scurvy, irritability, bone pain, easy bleeding, poor healing. Toxicity: gastric irritation, kidney stones, false positive tests for fecal occult blood or glucosuria.

Vitamin B1 (Thiamine): Important coenzyme in the metabolism of carbohydrates. Sources: meat, grains, legumes. Deficiency causes: alcoholism, dialysis, diet high in carbohydrates. Beriberi, Wernicke's encephalopathy.

Vitamin B2 (Riboflavin)

Insulin Action Times

Understanding the action times of different insulin types is crucial for effective diabetes management. Here's a breakdown:

• Rapid-Acting:
  • Examples: Actrapid or Humulin Regular
  • Onset: 20-30 minutes
  • Peak: 2-4 hours
  • Duration: 6-8 hours
  • Note: Crystalline insulin
• Intermediate-Acting:
  • Examples: Insulatard or Humulin NPH
  • Onset: 45-60 minutes
  • Peak: 6 hours
  • Duration: 12-14 hours
  • Note: Protamine insulin
• Long-Acting:
  • Examples: Monotard or Slow
  • Onset: 60-90 minutes

**Chemical Risk Assessment in the Workplace**

Hygienic Evaluation

  • United States (ACGIH)
    • TLV (Threshold Limit Value)
    • BEI (Biological Exposure Indices)
  • Spain (INSHT)
    • VLA (Environmental Limit Values)
    • VLB (Biological Limit Values)
• Maximum values allowed
  • USA (OSHA)
    • PEL (Permissible Exposure Limit)
  • Spain (Current Legislation)
    • Regulation of Troublesome, Unhealthy, Harmful, and Dangerous Activities
    • Specific regulations (benzene, asbestos, lead,
