We examined four staining methods on replicate smears of 313 respiratory specimens submitted for Pneumocystis jiroveci examination. The sensitivity and specificity of Calcofluor white stain (CW) were 73.8 and 99.6%, respectively. The sensitivity and specificity of Grocott-Gomori methenamine silver stain (GMS) were 79.4 and 99.2%, respectively. The sensitivity and specificity of Diff-Quik stain ...
Background and Aim: Management of iron-induced tooth pigmentation is challenging. This study aimed to compare the efficacy of sodium bicarbonate powder and pumice flour for removal of iron-induced pigmentation from primary ante-rior teeth. Materials and Methods: In this in vitro, experimental study, 60 sound primary anterior teeth were collected. After cutting the roots and sealing the pulp ch...
The recent paper by Rotimi and colleagues 1 does not mention the acridine orange stain 2 when comparing staining methods for the identification of Helicobacter pylori. The acri-dine orange stain uses ultraviolet fluores-cence in the identification of bacteria. The typical curved morphology of H pylori can easily be diVerentiated from other bacteria. I have used this quick, cheap, and reliable s...
A comparison of healing of corneal epithelial wounds stained with fluorescein or Richardson's stain.
The effects of fluorescein and Richardson's stain on corneal epithelial wound healing were compared in eyes of rabbits whose corneas had the epithelium removed by scraping or by n-heptanol. One eye of each rabbit was stained with fluorescein and the other eye was stained with Richardson's stain at intervals throughout the healing process, and the wounds were photographed for planimetry and dete...
