Abstract:
The urea test for diagnosis of Ménière's disease in 142 cases has been reported. The auditory alternations by dehydration tests with urea and glycerol were compared. Clinical observations demonstrate that the urea test gave the same positive rate as the glycerol test in patients with Ménière's disease. The adverse effects of urea are rather slight. It seems that the urea test be preferable to other methods of diagnostic dehydration. Guinea pigs were used to study the acute dehydration of the inner ear. The possible mechanism of dehydration was also discussed.
Insights
The urea test effectively diagnoses Ménière
Area of Science:
- Otolaryngology and audiology research.
- Investigating inner ear physiology and diagnostic methods.
Context:
- Ménière's disease diagnosis relies on specific audiological and vestibular tests.
- Dehydration tests are used to assess inner ear fluid balance.
- Comparing urea and glycerol as diagnostic dehydration agents.
Purpose:
- To evaluate the efficacy of the urea test in diagnosing Ménière's disease.
- To compare the diagnostic yield and adverse effects of urea versus glycerol dehydration tests.
- To explore the mechanism of acute inner ear dehydration.
Summary:
- A study involving 142 patients compared urea and glycerol dehydration tests for Ménière's disease.
- The urea test demonstrated a comparable positive rate to the glycerol test.
- Urea exhibited fewer adverse effects, suggesting it as a preferable diagnostic dehydration method.
Impact:
- Highlights the urea test as a potentially safer and effective diagnostic tool for Ménière's disease.
- Provides insights into inner ear dehydration mechanisms.
- Informs clinical practice regarding diagnostic dehydration strategies.
