The influence of circularly polarized electric fields (CPEFs) on the stability of multiarmed spiral waves is investigated. It is shown that CPEFs can change the period of the multiarmed spirals. The average period is an important quantity of multiarmed spiral and it must be larger than a threshold for stable multiarmed spiral. After a counter-rotating CPEF with suitable amplitude and period is ...

The pattern of injury seen in pediatric hand burns differs from adults because scald burns are most common. Many of these are difficult to assess at initial presentation. In addition, children develop less stiffness in response to immobilization. For these reasons, we have developed a conservative, expectant approach for treating most pediatric hand burns. Meticulous wound care, positioning, sp...

Biobrane(®) is commonly used in paediatric burns to cover partial thickness burns and donor sites of split thickness skin (SSG). The purpose of this study is to evaluate the use of Biobrane(®) in dressing SSG adjacent to skin graft donor sites or partial thickness burns. A retrospective review was undertaken to determine the use of Biobrane(®) in dressing SSG, where the grafted areas were adjac...

Hydrofluoric acid (HF) causes a unique chemical burn. Much of the current treatment knowledge of HF burns is derived from case reports, small case series, animal studies and anecdotal evidence. The management can be challenging because clinical presentation and severity of these burns vary widely. Plastic surgeons managing burn patients must have a basic understanding of the pathophysiology, th...

Facial burns are generally considered severe. This is due to the possibility of respiratory complications. First responders check the nostrils for singed hairs. In severe cases there may be soot around the nose and mouth and coughing may produce phlegm that includes ash. Facial and inhalational burns compromise airways. They pose difficulties in pre-hospital resuscitation and are challenge to c...
