Are the performed analytic tests a waste of the health service funds or are they really sufficient? In this case, after undergoing several tests to rule out potential causes of the prevailing symptoms, psychiatric evaluation revealed a triggering event that contributed to the diagnosis of psychogenic sneezing.

Immunohistochemical Localization of p53 in Human Thyroid Neoplasms: Correlation with Biological Behavior.

Molecular analyses of thyroid tumors have documented mutations in the tumor suppressor p53 gene almost exclusively in anaplastic carcinomas. In contrast, immunohistochemistry has localized p53 in differentiated papillary and follicular thyroid cancers. To establish the significance of p53 immunolocalization in these lesions, 78 thyroid tumors of follicular derivation were examined.
