We determined the prevalence rate of classes A, B and D β-lactamases among extended-spectrum cephalosporin (ESC)-non-susceptible Pseudomonas aeruginosa clinical isolates from burned patients. ⋯ VEB-1 and OXA-10 are the predominant ESBL genes and bla(VIM) is the dominate MBL gene in ESC-non-sensitive P. aeruginosa isolates in Saudi Arabia. VEB, OXA-10 and GES ESBLs have not been reported previously in Saudi Arabia and GES has not been reported previously in Middle East and North Africa.

Despite many educational campaigns we still see burns caused by methylated spirit every year. We undertook a retrospective study to analyse the impact of this problem. ⋯ The use of methylated spirit is an ongoing problem, which continues to cause severe burns in adults and children. Therefore methylated spirit should be banned in households. We suggest sale only in specialised shops, clear labelling and mandatory warnings.

Comparative Study
Comparison of five dermal substitutes in full-thickness skin wound healing in a porcine model.
The wound healing attributes of five acellular dermal skin substitutes were compared, in a two-step procedure, in a porcine model. Ten pigs were included in this experimental and randomized study. During the first step, dermal substitutes (Integra(®), ProDerm(®), Renoskin(®), Matriderm(®) 2mm and Hyalomatrix(®) PA) were implanted into full-thickness skin wounds and the epidermis was reconstructed during a second step procedure at day 21 using autologous split-thickness skin graft or cultured epithelial autograft. ⋯ We conclude there was no long-term difference of scar qualities in our study between the different artificial dermis. More, there was no difference between artificial dermis and the control group. This study makes us ask questions about the benefit of artificial dermis used in a two-step procedure.

Case Reports
Reconstruction of extensive upper extremity defects using pre-expanded oblique perforator-based paraumbilical flaps.
The pedicled paraumbilical flap is a reliable tissue transfer for hand and forearm reconstruction. However, its size, pedicle length and/or thickness limit its application in resurfacing of extensive defects of the upper limb. To conquer those limitations, this flap was pre-expanded for 10-24 weeks prior to transfer in 25 patients and used as a pedicle flap to cover upper extremity defects. ⋯ All flaps survived, but two had partial flap necrosis due to venous congestion or infection. With pre-transfer expansion, a large, well-perfused abdominal pedicle flap can be raised and transferred based on the paraumbilical perforators. This pre-expanded flap might be useful in the patients who have the extensive upper limb defects and sufficient time to allow tissue expansion.

Postburn ankle scar contractures cause functional limitations of all lower extremities and create a serious cosmetic defect, not allowing patients to use normal foot wear, and, therefore, needing surgical reconstruction. The anatomic features of ankle dorsiflexion contractures and their treatment have been covered in the literature far less than other joint contractures, and their treatment is still a challenge for many surgeons. A common treatment method is incisional release of the contracture and defect resurfacing with skin graft. Rarely, distally based sural or free flaps and Ilizarov fixator are used. ⋯ Three anatomic types of ankle dorsiflexion scar contractures were identified: edge, medial, and total. An anatomically justified technique for edge and medial contractures is trapeze-flap plasty; total contractures are effectively eliminated with scar excision and skin grafting.
