Burn injuries caused by fireworks: effect of prophylaxis.

During the New Year 1991-92, a total of 17 patients with burns caused by fireworks (an unprecedentedly high number) were admitted to the two Danish burns units. They were all males and all had carried the causative firework in their clothes; 88 per cent were minors, and 87 per cent of these had bought their fireworks themselves in ordinary shops. Fireworks described as 'whistles' were responsible in 88 per cent of the cases. Appeals to the authorities resulted in a change of the legislation in November 1992, allowing only whistles equipped with safety fuses. Altogether 25 tons of unauthorized fireworks were confiscated and destroyed before January 1993. Campaigns were conducted at all schools and in the media in November and December 1992 and 1993, giving information about the dangers of carrying fireworks close to the body. During the New Year 1992-93, only four children were admitted with firework burns; the number of patients was significantly lower than in the preceding New Year, as was also the extent of their burn injuries. Furthermore, the patients were all younger than the age group targeted by the school campaign. The following New Year 1993-94, only three children were admitted with minor burns caused by fireworks, confirming the effect of the prophylactic actions. We conclude that the prophylactic actions were effective enough to reduce the number and severity of burn injuries caused by fireworks.

[Burns due to fireworks. A 4-year study of the incidence and causes with suggestions for prevention].

During the period around New Year 1991-1992, significantly more patients were admitted to the burns units in Denmark with burns caused by fireworks, compared to the previous three years. All patients were males and 88% under 18 years of age. The areas burned were localized primarily to the thighs and the front of the body. The main causative fireworks were whistles. Analyses revealed the fuses to be highly combustible. New directives have been issued, requiring whistles to be equipped with safety fuses. Although 70% of the patients were aware that fireworks should not be carried close to the body, the message has not been sufficiently stressed. A campaign for the oncoming New Year, informing about burns, eye and hand injuries caused by fireworks is under preparation. Although sale of fireworks to persons under 18 years of age is prohibited, more than 80% of the children had purchased the fireworks themselves. We recommend reinforcement of the law.

Temporary arteriovenous shunt prior to free flap transfer.

The establishment of a temporary arteriovenous shunt (TAVS) near a recipient site with inadequate local vessels may facilitate the subsequent re-vascularization of a free flap. In nine patients a TAVS was constructed prior to the transfer of free flaps. The indication was either the absence of vessels or inadequate recipient vessels. In eight of the nine patients the establishment of the shunt proved successful. In one patient a re-creation of the shunt was necessary owing to thrombosis caused by infection. In another patient the shunt thrombosed and no further microvascular surgery was possible. The construction of a TAVS increases the possibility of more extensive application of free flap transfer. Should the creation of the shunt prove futile, the donor flap may still be salvaged for further application. A staged transfer of a free flap after the primary establishment of a TAVS gives the best changes for adequate vascularization of the flap and reduces the risk of thrombosis.

Allograft vs. exposure in the treatment of scalds--a prospective randomized controlled clinical study.

In a randomized controlled clinical trial (RCCT) the healing rate, infection and late cosmetic/functional results were investigated in 48 children admitted to hospital with scalds. They were treated with either exposure treatment (EP) or lyophilized allograft (LA). Healing rate was improved with LA treatment. The infection tendency was identical within the two groups. Late cosmetic/functional results were superior, with LA treatment compared to exposure treatment but only in the subgroup of superficial dermal scalds.

Simultaneous bilateral cancer of the brease--evaluation of the use of a contralateral biopsy.

During a five-year period 299 female patients with breast cancer were treated by mastectomy. In 170 of the patients a biopsy of the contralateral upper lateral quadrant was performed during the operation. In 164 of the patients with primary carcinoma of ductal origin only 7 cases of malignancy in the contralateral biopsy were observed. In six females (3.5%) the primary cancer was of lobular origin and in three of these patients (50%) the contralateral biopsies showed lobular carcinoma in situ (LCIS). It is concluded that random contralateral biopsies of the breast should be restricted to patients with a primary cancer of lobular origin.
