[Intracranial tumor behavior of plasma cell neoplasms. Report of 2 cases and literature review].

Background: Multiple myeloma is a plasmatic cell neoplasm that is characterized by skeletal destruction, renal failure, anemia and hypercalcemia. The skull plasmacytomas represent less than 1% of the head and neck tumors, they can be the primary lesion or occur as a secondary manifestation of multiple myeloma in 20-30% of the patients, or they can even manifest several years later after the diagnosis of plasmacytoma. Although some of the lesions may be surgically accessible, the aggressive natural behavior will complicate the evolution of the patients.

Ping pong fractures: treatment using a new medical device.

Purpose: The aim of this study was to assess the use of a new medical device to elevate depressed skull fractures (DSFs) in newborns and minor infants.

Methods: Nine patients (ranging from 1 day to 9 months of age) with simple DSF underwent skull elevation by a new elevator medical device. This medical device comprises two elements: a pediatric resuscitator (CPR mask) connected to a 50-ml syringe.
