The pH of the skin is slightly acidic (4.6 to 5.8) which is important for appropriate antibacterial, antifungal, constitution of barrier function, as well as structuring and maturation of the stratum corneum. This study aimed to evaluate the pH of the main commercial moisturizers and liquid soaps in Brazil. Thus, pH of the products was quantified by pH meter in three measurements. A total of 38...

In 20 patients studied under general anaesthesia, we found good agreement between gastric fluid volumes aspirated blindly and total volumes determined by fibreoptic gastroscopy (mean under-estimation 6 ml (22%); range 0-50 ml). Gastric fluid acidity measurements using an electronic pH meter and pH indicator paper also provided results with good agreement (mean difference in pH 0.1; range -0.3 t...
