Modified Bleach Method – Improving Microscopic Detection of Acid Fast Bacilli in Fine Needle Aspiration Smears of Lymph Nodes
Background: Ziehl-Neelsen (ZN) method proves to be a good modality of microscopic detection of Acid Fast Bacilli (AFB) in Fine Needle Aspiration (FNA) smears of lymph nodes though has a low sensitivity. It has a potential to become an even more valuable tool if its sensitivity could be increased. Objective: To improve microscopic detection of AFB in FNA cytology of lymph nodes using modified bl...
متن کاملComparision of the Diagnostic values of Doppler Sonography with Fine Needle Aspiration in Thyroid Nodules
Introduction: Thyroid nodules are frequent occurrences, and whenever diagnosed, it is necessary to rule out of malignancy. Valuable diagnostic methods in this field are sonography and fine needle aspiration. In this study while investigating these two methods, we compared them with postsurgical pathologic findings. Materials and methods: This is a cross sectional, descriptive-analytical study. ...
متن کاملComparison of machine and manual staining of direct smears for acid-fast bacilli by fluorescence microscopy.
Comparisons were made in Lusaka and in London between manual staining and staining in an automatic machine with auramine-phenol of direct smears of sputum and other types of specimen for acid-fast bacilli. No evidence was obtained of carry-over of acid-fast bacilli from positive to negative smears during machine staining. There was improved contrast between bacilli and the background in smears ...
متن کاملKi-67 staining in histological subtypes of breast carcinoma and fine needle aspiration smears.
Thirty four cases of invasive breast carcinoma were analysed for heterogeneity of Ki-67 reactivity in a tumour, and proliferative activity in various histological subtypes was compared. The growth factions determined in areas of central and peripheral tumour were the same. Mucinous and lobular carcinoma showed lower Ki-67 activity than ductal carcinomas. When ductal carcinomas were subdivided a...
متن کاملDiagnostic Fine Needle Aspiration in a Case of Riedel’s Thyroiditis
In Riedel’s thyroiditis, a rare chronic inflammatory disease of thyroid gland, fine needle aspiration is usually non-diagnostic because most often only follicular cells are obtained and not the fibrous material characteristic of this type of thyroiditis. Therefore the diagnosis is often only established by histopathologic study of the surgically obtained biopsy. The illustrated case is a 46-yea...
