Cylindromas of the base of the skull. Report of four cases.

Cylindromas are rarely encountered in the neurosurgical field. Four cases of this rare tumor are presented. Conventional and computerized tomography scanning were most useful in establishing the diagnosis; angiography did not provide any further information. Because these tumors are well demarcated from surrounding structures, even in cases of recurrence, surgery is the treatment of choice. Radiation therapy is useful in the postoperative management. Long survival times with multiple recurrences are the rule.

[Use of a microcomputer for simplified data processing of ENT case-records employing a commercial program (author's transl)]. / Micro-informatique : gestion simplifiée des dossiers ORL sur programmme commercial.

Combined use of a microcomputer of sufficient capacity and a commercial program for data processing permits simple storage and exploitation of hospital case-records in an ENT department of moderate size. The principal advantages of the system reside in its permanent availability, the ease of communication with the computer due to the clear language employed, its large storage capacity (650 case-records per diskette), and the moderate cost involved. Programming time is reduced by the use of a particular nomenclature for questions and possible replies. The system is not static, and can be adapted to individual needs or modifications in pathology.
