Unlabelled:
The Bristol Stool Form Scale is used for describing feces. The objective of this research was its translation, cultural adaptation and validation for Brazil. The methodology was translation, back-translation and discussion. Validation involved 85 nurses, 80 doctors, and 80 patients, who correlated images of seven types of feces with the descriptions.
Results:
there was a difference in sex distribution, with males predominating among the doctors and females among nurses and patients. In relation to concordance between definitions and pictures, the highest percentage was in type 5 in all three groups and the lowest was in types 6 and 7 for the doctors, in type 3 for the nurses, and type 6 for the patients. The general Kappa index was 0.826.
Conclusion:
the scale demonstrated high reliability for all the groups studied.

Sputum culture and sensitivity is a medical procedure used to diagnose bacterial infections in the respiratory tract and select the most appropriate antibiotics for treatment. This process involves analyzing sputum samples of thick and opaque secretions produced in the lungs and airways. These samples are collected from patients and then sent to the laboratory for analysis.
