Intraoperative measurement for a new transcutaneous bone conduction hearing implant.

Objective: To investigate the possibility of using a modified reverse transfer function (RTF) measurement intraoperatively during surgery of a new transcutaneous bone conduction hearing implant to evaluate the status of the device.

Methods: Tests were performed on a cadaver skull (preclinically) and two conductive hearing loss patients implanted with a new transcutaneous bone conduction implant. During intraoperative activation, the RTF was measured using a microphone attached perpendicularly and directly to the skin in the middle section of the forehead.

Active middle ear implant compared with open-fit hearing aid in sloping high-frequency sensorineural hearing loss.

Objective: To compare 2 open-ear hearing solutions for sloping high-frequency sensorineural hearing loss: open-fit hearing aid (HA) and active middle ear implant (AMEI).

Study Design: Within-subjects prospective design.

Setting: Tertiary referral hospital.

[Cystic dystrophy on an aberrant duodenal pancreas. Apropos of a case].

Cystic dystrophy of the aberrant pancreas is a rare poorly understood condition which is difficult to diagnose and treat. The primary clinical signs are epigastralgia associated with poor general health and complications due to stenosis of the duodenum. Endoscopy gives the most information on tissue lesions and cystic formations in the duodenal mucosa.

[Predictive factors of recurrence in surgically treated rectal villous tumors. Therapeutic approach based on 184 cases].

The aim of this retrospective study on 184 operated cases was to propose a therapeutic management scheme for villous tumours of the rectum. Among the 184 operated patients, 167 (90,7%), mean age 65 years, were seen after a follow-up of 2 to 20 years. The tumour was most often localized in the rectal ampoula (141 cases) and was benign in 65 p.
