sentinel lymph node is the first regional lymph node that drains the lymph from the primary tumor. it is potentially the first nodeto receive the seeding of lymph‑borne metastatic cells. this study aimed to discuss lymphoscintigraphy procedural guidelines fordetection of sentinel node using tc‑phytate in isfahan, iran. moreover, the preliminary results of the first year’s clinical experience of...

Squamous cell differentiation (SCD) may occur in papillary thyroid carcinoma (PTC) only at metastatic sites. We have studied cytokeratin CK5/6 and P63 along with TTF1 (thyroid transcription factor 1)  and B-Raf (V-Raf murine sarcoma viral oncogene homolog B1) immunohistochemical expression in neck lymph node metastases of thyroid PTC showing SCD. The patient (21-years) presented wit...

Background: Cervical cancer is the second most common type of cancer among women. Effective screening programs can help cancer detection in early phases and reduce death. Metastasis to lymph nodes is one of the most prognostic factors in patients who underwent surgery. Also, a positive result from pathology report alert oncologist as a cause of death. Sentinel lymph node biopsy has been widely ...

follicular dendritic cells or dendritic reticulum cells are important components of the immune system essential for antigen presentation. malignancies arising from these cells are uncommon and the first case was reported in 1986. the most common sites of follicular dendritic cell sarcomas are lymph nodes, especially cervical, axillary and mediastinal regions, but extranodal sites including head...

background: ventriculoatrial (va) conduction has an important role in the initiation and maintenance of some arrhythmias. the aim of this study was to evaluate whether clinical and electrophysiological parameters of atrioventricular (av) conduction can predict va conduction. methods: detailed demographic, electrocardiographic, and echocardiographic data were recorded in 54 consecutive patients ...

kawasaki disease is believed to be the commonest vasculitis of medium vessels in asian children. however, the majority of children with kawasaki disease continue to remain undiagnosed perhaps because of the lack of awareness amongst pediatricians. the clinical features of kawasaki disease can be confused with other common conditions such as scarlet fever, stevens johnson syndrome, measles fever...

wireless sensor networks are composed of hundreds or thousands of small nodes called sensor that work together and are associated with a specific task or tasks to do. each of these nodes includes sensor, processor, communication components, a small memory and a source of energy. it is expected that wireless sensor networks will be used widely in many applications in near future. scalability and...

discussion benign metastasizing pleomorphic adenoma is a rare and controversial but distinct clinical entity. although the definition of the term benign precludes metastatic disease, these tumors do not demonstrate any malignant features yet metastasized to distinct sites. it remains to be determined whether this benign metastasizing pleomorphic adenoma is really low grade salivary malignancy. ...
