V-Y-S-plasty closure of circular defects.

Standard ellipse excision of lesions followed by direct closure results in a linear scar. Linear scar contracture may disrupt adjacent anatomy, rendering negative functional and cosmetic outcomes. This is of particular relevance when operating in the vicinity of paired or symmetrical anatomic structures. The V-Y-S-plasty closure of circular defects conserves tissue and all but eliminates the need for undermining of wound edges. It is ideally suited for the closure of defects adjacent to the canthi, eyelids, eyebrows, lip commissures and nasal alae. The V-Y-S-plasty is also useful for the extremities where skin is under considerable tension. The technique and our refinements are described.

Drain fixation made foolproof.

A reliable method of securing drain tubing is presented. Knots made from two half-hitches have been used in the sailing world for many years. They provide a strong, slip-free knot which is simple to learn, tie, teach and easy to remove.

Cement-related burns.

Burns caused by prolonged contact of wet cement with skin are common in this country. Recent literature has highlighted other ways in which the use and manufacture of cement can lead to burn injuries, notably through explosion and contact with hot powder during manufacturing. These injuries are uncommon in this country and potentially very serious. Case studies are presented of two men injured in such a way in the same incident at a cement-manufacturing plant.
