ABSTRACT
The post-traumatic origin of benign paroxysmal positional vertigo remains the most likely, from a patho-physiologic point of view. Benign paroxysmal positional vertigo due to surgical "traumas" has been described in the medical literature. According to personal experience, these iatrogenic cases represent a rare possibility and may be the consequence of surgical interventions differing according to the anatomical district involved and surgical technique performed. The temporal relationship with the surgical action and clinical features may be involved in some of these cases, even if it is not possible to define any real cause-effect link. Herewith some cases of paroxysmal positional vertigo are described, strongly held to be of iatrogenic origin, focusing on dental and maxillo-facial surgery as risk factors for benign paroxysmal positional vertigo.

Occupational exposure to asbestos has been associated with an increased incidence of lung and gastric cancers, mesotheliomas, and myelolymphoid malignancies. A new observation of a patient with indirect exposure to asbestos who developed mesothelioma and plasmacytoid lymphocytic non-Hodgkin's lymphoma is described. This report and the previously described stimulation of B lymphocytes by asbestos suggests that the association of mesothelioma with lymphoid and plasma cell malignancies is not merely a coincidence.
