Background: In cytological fixatives prior to Papanicolaou staining smears are fixed mostly in alcohol or any alcohol based special purpose fixative. Alcohols are costly, hazardous and also there is a problem of disposal. Here, a very cheap and easily available alternate for fixative was being used. The objective was to describe the efficacy of 20% honey as a cytological fixative in comparison to ethanol.Methods: The study was done on buccal smears from students of Department of MLT, Government Medical College, Thiruvananthapuram, Kerala, India for a period of six months after ethical approval. Two buccal smears were collected from either cheek using wooden spatula/blunt end of the Ayers spatula. One of the smear is fixed in ethanol (95%) and the other smear is fixed in honey (20%). The slides were scored based on the assessment parameters: nuclear staining, cytoplasmic staining, cell morphology, clarity of staining and uniformity of staining.Results: The study was done on buccal smears, the sample were smeared and fixed onto slides using two fixatives- 95% ethanol and 20% honey. Both reported good quality staining feature, preservation of morphology and a crisp nuclear and cytoplasmic staining. It has also added advantage of being nontoxic, economical, non-flammable, non-hazardous, no problems associated with license of purchase, reduces overall turnaround time and is easy to handle without any sort of irritation.Conclusions: Thus, the overall study shows that honey has got a fixative action, which can be implemented soon in the industry.
Fine Needle Aspiration Cytology is the preliminary investigation employed for superficial and deep swelling in the body. It provides early information regarding the lesions before performing biopsy and aid in the treatment plan of the patient. However sample inadequacy from representative lesion may render patients to repeat aspirations and may also cause delay in reports. There is an ever increasing demand for rapid diagnosis in cytology. The present study was conducted to assess the utility of brilliant cresyl blue as a rapid stain in fine needle aspiration cytology. Objective: To assess the utility of rapid Brilliant cresyl blue (BCB) stained wet mount preparation in routine fine needle aspiration cytology. Materials and Methods : The study was carried out in the Cytology laboratory, Govt. Medical College Thiruvananthapuram and PG Pathology Lab, Department of MLT, Govt. Medical College Thiruvananthapuram for a period of six months. A total of 50 cases referred to cytology laboratory for FNAC were included in this study. A wet mount preparation with Brilliant cresyl was prepared immediately after aspiration and examined for cellular adequacy and cytomorphology, which was then compared with the routine Papanicolau stained smear . Results & Conclusion:In situations for rapid diagnosis, and to assess the cellular adequacy of a lesion Brilliant cresyl blue staining method is very helpful. Most of the cases diagnosed as malignant on Brilliant cresyl blue staining correlate with the Pap stain. All the cases diagnosed as benign on rapid brilliant cresyl blue stain were also diagnosed as benign with Pap stain. The result clearly indicate that the brilliant cresyl blue stained wet mount preparation can be used as a rapid supplementary diagnostic procedure in FNAC at least for urgent reporting and sample adequacy assessment.
