A total of 246 consecutive burn patients younger than 2 years and older than 70 years of age admitted to a burn center were reviewed retrospectively to study morbidity and mortality specific to these two age groups. Of these patients, 165 were less than 2 years of age and 81 were over 70 years of age, representing 16% and 8% of the total patient population respectively. In patients under 2, scald burns occurred in 127 (77%) and flame burns in 18 (11%). ⋯ A total of 36 complications occurred in the younger age group (0.2 complications per patient) and 111 in the older age group (1.4 per patient). Burn wound sepsis was the most common complication in each group, occurring in 28 patients under 2 and 42 elderly patients, and was responsible for the 1 death in the younger age group. Although burn wound sepsis was the most common complication in those patients over 70, cardiovascular and pulmonary complications were the most deadly, accounting for 68% (28 patients) of total deaths in this group.

Hemodynamic alterations secondary to an electrical burn in the rat: a pilot study.
Rats subjected to a standard electrical burn of 250 volts for 10 seconds receive a severe injury stimulating a pronounced systemic circulatory response. Initial postinjury hyperemia is replaced by a low perfusion state within 24 hours. Our study demonstrates the difficulty in isolating regional microcirculatory alterations under such circumstances. Modification of the burn model or the method of fluid resuscitation may minimize the influence of this dynamic systemic response.

Eleven circumscribed, full-thickness burns were treated in 9 patients with immediate excision and primary closure of the defect or by using a variety of local random cutaneous and musculocutaneous flaps. The burns were located on the face, trunk, and extremities. In 2 patients this technique was used in the management of smaller burns on one surface of the body, thus facilitating skin grafting of larger wounds on the opposite surface. ⋯ The timing of the excision and closure varied from 2 hours to 2 weeks following thermal injury, with no postoperative wound infections. In selected cases primary excision of deep burns and closure by use of local tissue approach ideal treatment. With certainty of the depth of destruction, this procedure should be carried out regardless of locality when technically and anatomically feasible.

Experimental study of vascularized nerve grafts: morphometric study of axonal regeneration of nerves transplanted into silicone tubes.
Rat sciatic nerves were used in a comparative study of vascularized and free (nonvascularized) nerve grafts transplanted into silicone tubes. A total of 39 sciatic nerves were used, 21 as vascularized nerve grafts and 18 as free nerve grafts. ⋯ Furthermore, the diameters of myelinated axons in the vascularized nerve graft were larger than those in the free nerve graft at all specimen sites during all postoperative weeks. We suggest that the preservation of the vascular system in vascularized nerve grafts would decrease the likelihood of fibrosis and result in better regeneration of axons.

The oft-quoted 5-cm rule for melanoma excision is not valid. Substitute guidelines are offered and their scientific basis is discussed. A 1-2-3-cm rule is carefully outlined in terms of maximum rather than minimum margins, because little evidence exists to support the importance of wide excision limits in the treatment of melanoma.
