BACKGROUND Lichen planus is considered to be the most common dermatological disease involving the oral mucosa. OBJECTIVE To investigate the profile, clinical features, and the presence of dysplasia and candidiasis in patients with oral lichen planus. METHODS A total of 21 patients were selected from 258 patients at risk for oral cancer development. RESULTS Most of the patients were white ...
The Papanicolaou Society of Cytopathology has developed a set of guidelines for pancreatobiliary cytology including indications for endoscopic ultrasound guided fine-needle aspiration biopsy, techniques of the endoscopic retrograde cholangiopancreatography, terminology and nomenclature of pancreatobiliary disease, ancillary testing, and postbiopsy management. All documents are based on the expe...
Lettuce infectious yellows virus (LIYV) encodes a 26 kDa protein (P26) previously shown to associate with plasmalemma deposits (PLDs), unique LIYV-induced cytopathologies located at the plasmalemma over plasmodesmata pit fields in companion cells and phloem parenchyma. To further characterize the relationship of P26 and PLDs, we assessed localization and cytopathology induction of P26 expressed...
A unique space oriented filer is presented in order to detect and isolate the cell of a nucleus for applications in cytopathology. A classification method for nuclei is then considered based on the application of a set of features which includes certain fractal parameters. Segmentation algorithms are considered in which a self-adjustable sharpening filter is designed to enhance object location....
BACKGROUND Despite lack of adequate, validated, independently performed clinical studies, several molecular tests are commercially available on the market and are being used on indeterminate thyroid nodules to guide patient-care decisions. METHODS We summarize the current evidence on the role and limitations of molecular tests used in combination with thyroid cytopathology to refine the presu...
