Abstract

On Earth, the functional stretch reflex is an important component in the maintenance of posture and muscle tone. In parabolic flight experiments, we evaluated whether the functional stretch reflex, as reflected in the tonic vibration reflex, adjusts appropriately for changes in background gravitoinertial force level. Virtually immediate alterations of appropriate sign occurred.

Function of the sensate free forearm flap after partial glossectomy.

AIMS: To compare functional recovery of sensitive free forearm flaps with non-sensitive free forearm flaps, following reconstruction for partial glossectomy. MATERIAL: Sixteen patients underwent partial glossectomy for oncological reasons, of whom: nine patients underwent repair with non-sensitive free forearm flaps (group A) and seven with sensitive free flaps (group B). METHODS: All patients underwent the following tests: (1) tactile sensitivity evaluation, localization of stimulus, sharp/blunt definition, discrimination between two points (static and dynamic), thermal sensitivity to heat/cold; (2) speech evaluation by means of the modified Fanzago test; (3) subjective evaluation concerning the degree of satisfaction of the following functions: swallowing, feeding and talking. RESULTS: The sensitivity and logopaedic evaluation tests and the subjective evaluation charts highlight an overall better functional recovery of the sensitive repair than the non-sensitive ones. CONCLUSION: In patients who have undergone partial glossectomy repair with free forearm neurofasciocutaneous flaps allow good recovery of oral functions and, therefore, a good quality of life.

Epithelioid sarcoma arising on the forearm of a 6-year-old boy: case report and review of the literature.

Epithelioid sarcoma is a rare malignant tumor that occurs mainly in young adults and most frequently involves the distal portion of the upper extremities. The tumor is particularly rare in children and more frequently involves the head and neck; only one case involving the forearm has been reported in a child under 10 years of age, and he was treated with amputation. We report the case of a 6-year-old boy with an epithelioid sarcoma of the forearm whose initial management had been inappropriate. The patient was ultimately treated with limb sparing surgery. Two years later, no local recurrence was evident but pleural metastases were detected.

Venous flow-through flap as an external monitor for buried radial forearm free flap in head and neck reconstruction.

Postoperative monitoring of buried free flaps in head and neck reconstruction can be extremely difficult or impossible. The authors describe a series of 11 cases over a 21-month period, of buried radial forearm free flaps used in head and neck reconstruction. To monitor the main buried flap a small venous flow-through flap is supplied by and attached to the cephalic vein of a radial forearm free flap. This small venous skin flap is inset separately from the main paddle, so that it is visible at the external surface of the neck, furnishing information about the perfusion of the entire flap.
