Cell block technique as a complementary method in the clinical diagnosis of cyst-like lesions of the jaw

OBJECTIVE: To evaluate the applicability of the cell block technique as a complementary method for presumptive diagnosis in the analysis of cyst-like aspirates from jaw lesions prior to histopathological diagnosis. MATERIAL AND METHODS: The sample was made up of 17 cyst-like jaw lesions. After puncture, the aspirates were centrifuged, fixed in formalin, embedded in paraffin and processed. All lesions were biopsied and submitted to histopathological examination. RESULTS: In 9 cases, the cytopathological analysis using the cell block method showed a predominant presence of erythrocytes, inflammatory cells and few epithelial cells. In the other 8 cases, the cell block technique demonstrated the presence of parakeratin, whose histopathological analysis confirmed the occurrence of keratocystic odontogenic tumors (KOTs). CONCLUSIONS: According to the studied cases, the cell block method was proven to be a simple, fast and low-cost technique to effectively differentiate KOTs from other lesions with similar clinical and radiographic features. The cell block technique comprises cellular preparations useful to determine a clinical diagnosis and help to develop a therapeutic plan for those lesions

Contexts of Twinship: Discourses and Generation

Much of the research relating to twins is concentrated in biology and psychology where twins have been used as methodological tools for testing for the relative influences of nature and nurture. This chapter demonstrates a sociological approach to the study of twinship by situating twinship within a social and cultural context. It examines how discourses of twinship, childhood and ‘growing up’ bring meaning to and frame our understanding of twinship. It also draws attention to the significance of family life, especially family relationships and generation in contextualising twins’ experiences and variously facilitating and inhibiting their agency

HYPERSTOMY SYNDROME - A NEW APPROACH FOR THE TREATMENT OF LYMPHEDEMA OF THE LOWER LEGS

To improve the results after surgical treatment of thelower legs' lymphedema, a new approach was developedby surgical ligation of the abnormal arteriolovenularshuntings. (Hyperstomy Syndrome). Thesefindings are very common in congenital and postphlebiticlymphedemas. The abnormal branchingsare easily localized by serial arteriography. The excisiontechniques like the Charles' operation, presentsafter this new method much better esthetic appear-ance with out formation of hyperkeratosis or verrucouswarts commonly found after these operations
