The effectiveness of Levodopa can be reduced when taking:
- A. Pyridoxine
- B. Bromocriptine
- C. Amantadine
- D. Amantadine
Correct Answer: A
Rationale: The correct choice is Pyridoxine. Levodopa is a precursor to dopamine and is commonly used in the treatment of Parkinson's disease. Pyridoxine, also known as vitamin B6, has been shown to reduce the effectiveness of Levodopa by accelerating its conversion to dopamine in the bloodstream before it reaches the brain. This reduces the amount of Levodopa available to provide therapeutic benefit in Parkinson's disease. It is important for patients taking Levodopa to be cautious about taking vitamin B6 supplements to avoid diminishing the efficacy of their medication.

Recent studies indicate that a deficiency of which vitamin correlates with increased morbidity and mortality in children with measles?
- A. A
- B. C
- C. Niacin
- D. Folic acid
Correct Answer: A
Rationale: Recent studies have shown that a deficiency of vitamin A correlates with increased morbidity and mortality in children with measles. Vitamin A plays a crucial role in supporting the immune system and helps protect against severe complications of measles, such as pneumonia and vision problems. Children with measles are at higher risk of vitamin A deficiency due to factors such as decreased intake and increased utilization of vitamin A during infection. Providing vitamin A supplementation to children with measles has been shown to reduce the severity of the disease and improve outcomes. Therefore, ensuring adequate vitamin A levels is essential in the management of children with measles to reduce morbidity and mortality.
