[Danger in the pocket: explosive e-cigarette]. / Gefahr in der Hosentasche ­ explosive E-Zigarette.

INTRODUCTION: Be it as a nicotine replacement or a fashionable seduction for young people or casual smokers with or without nicotine additives - the popularity of e-cigarettes in Europe has increased during the past decade. In addition to the potential of long-term pulmonary damage, which is still largely unknown to date, there is a risk of battery explosion with specific injury patterns. Most users are unaware of the danger in their pockets. MATERIAL AND METHODS: Between February and July 2019, four patients were treated with burns from exploded e-cigarettes in the burn centre at Sana Hospital in Offenbach am Main (Germany). This article describes the cause and extent of the injury and its treatment. RESULTS: In all patients, the cause of the explosion was what is called "thermal runaway" (very rapid discharge of the battery). The average age of the patients, who were exclusively male, was 37 (25-50) years. The combustion depth ranged from grade I to deep grade IIb. The burnt body surface averaged 3 % (0.5-4.5 %) TBSA and affected the body regions that are typically in direct contact with the e-cigarette: thighs, genitals and hands. Conservative treatment was successful in one case and surgical treatment in two cases (two alloplastic covers, one meshed split-skin transplant). One patient discharged himself from hospital against medical advice after initial treatment. The average time in hospital for the three remaining patients was 15.6 days (6-17). CONCLUSION: Burns from an exploding e-cigarette represent a rare new entity. The force of the explosion of the battery body leads to injury patterns that require treatment in specialised centres with the entire spectrum of burn care. Mixed injuries with deep burns occur at the predilection sites due to thermal action, colliquative necrosis due to leaking electrolyte fluid and contamination by foreign bodies (metallic lithium, splinters of the destroyed housing) and require special initial measures. The extinction of fire caused by e-cigarettes also requires special measures. Proper handling of CE-certified devices is essential. Manipulation of the device in the event of defective functions or defective batteries is highly dangerous and should be strictly prohibited. General security requirements must be observed.

[Treatment options for burn injuries of the hand - an update]. / Aktuelle Behandlungsmethoden bei Verbrennungen der Hände.

Burn injuries of the hands happens very often. Up to 80 % of all severe burn victims suffer from a participation of their hands. A meticulous reconstruction of these areas is mandatory due to their important properties in form, function and aesthetic outcome. The treatment options actually are impressed by the efforts to reduce invasiveness, to increase the selectivity of necrectomy as well as the natural capacity of tissue regeneration.

Management of donor site infections in split-thickness skin graft with water-filtered infrared-A (wIRA).

Infection of donor sites in split-thickness skin grafts is one of the complications of skin transplantation. Nutrition status and associated diseases play important roles in healing of donor sites. There are different ways used to treat infected donor sites. Water-filtered infrared-A (wIRA), as a special form of heat radiation with a high tissue penetration and a low thermal load to the skin surface, can improve the healing of acute and chronic wounds both by thermal and thermic as well as by non-thermal and non-thermic effects. Water-filtered infrared-A (wIRA) increases tissue temperature, tissue oxygen partial pressure and tissue perfusion. These three factors are decisive for a sufficient supply of tissue with energy and oxygen and consequently also for wound healing and infection defense. This was confirmed in a case with a late severe healing disturbance of the donor sites after skin transplantation.

A Severely Burned Hemophiliac.

Patients suffering from moderate or severe hemophilia A are particularly vulnerable to trauma injury, being on high risk of immediate exsanguination. Due to a rareness of this disease, there are very few reports about the management of severe injuries of the affected patients. No guidelines for the management of burn trauma of hemophiliac patients have been yet established. Since, to our knowledge, this is the first case report about a successful treatment of a severely burned hemophiliac, requiring intensive care, long-time intubation, and multiple epifascial necrosectomies of third grade wounds, the authors are proposing the approach to this condition. The factor VIII has been substituted, enhancing its activity to over 70% during the planned interventions and keeping it above 30% in the intervals between the operations. To minimize the risk of surgical bleeding, our therapeutic strategy consisted of multiple short radical operations. The patient was healed and was dismissed after 68 days. The surgical blood loss was comparable with noncoagulopathic patients with similar burn extension. In case of a vast burn injury of the moderate or severe hemophiliacs, where the trauma-related consumption coagulopathy is expected and deep necrosectomies are required, the authors suggest starting a substitution of the factor VIII immediately after the admission, followed by a structured operative planning.
