Aberrant external jugular vein phlebectasia with tongue pain.
We have not encountered any other report of phlebectasia with tongue pain in the literature. The pain disappeared after the anomalous venous communication was excised.

Low-cost, high reliability voice control unit (VCU).
A dedicated microcomputer system has been developed to provide voice control over a wide variety of motorized devices. Employing a 8051 microprocessor with 16 kilobytes of ROM and 16 kilobytes of non-volatile RAM, the system potentially realizes an OEM cost of under $100. Other features include: a simplified user interface, a failsafe stop and voice programmable capabilities. This system has the potential to bring voice control into the marketplace in a wide variety of applications. Currently, the system has been adapted to surgical microscopes and is used in controlling several types of hospital beds.

Successful cryopreservation of microvenous allografts.
Vein grafts are used in approximately 20% of microsurgical cases. Although autogenous veins currently form the major source, they are associated with increased operating time and donor site scars. Cryopreserved allograft veins may serve as an alternative source. To our knowledge, cryopreservation of veins (1 mm or less) has not been reported. In this article we have described the process of cryopreserving rat veins (less than 1 mm in diameter) and their preliminary use as interpositional vein grafts.
