Survey on the bacterial flora and their resistance to antibiotics in hospitalized burn patients on tropical islands / 中华烧伤杂志

<p><b>OBJECTIVE</b>To investigate the bacterial flora and their drug resistance in hospitalized burn patients on tropical islands.</p><p><b>METHODS</b>Retrospective study was carried out to analyze pathogenic microorganisms and their drug resistance characteristics in 392 burn patients hospitalized during 2000-2005.</p><p><b>RESULTS</b>(1) Totally 671 strains of bacteria were isolated, among which Pseudomonas aeruginosa, Staphylococcus aureus, Aerobacter cloacae and Acinetobacter species were predominant, but the isolation rate of Pseudomonas aeruginosa was declining compared with that in 1990's. (2) The resistance rate of Pseudomonas aeruginosa to imipenem and cefepime was 32.2% and 36.7% , respectively, while that to other antibiotics was above 80%. (3) Among 141 strains of Staphylococcus aureus, 89 strains (63.1%) of MRSA were isolated, and none of them were resistant to Vancomycin.</p><p><b>CONCLUSION</b>Pseudomonas aeruginosa, Staphylococcus aureus, Aerobacter cloacae and Acinetobacter species were predominant in tropical islands. The species of the pathogens are changing . The drug resistance rates of Pseudomonas aeruginosa and Staphylococcus aureus are rather high.</p>

The reverse medialis pedis flap for coverage of forefoot skin defects / 中华整形外科杂志

<p><b>OBJECTIVE</b>To study a new method to repair forefoot skin defects.</p><p><b>METHODS</b>Based on anatomical studies, a reverse medialis pedis flap was designed for coverage of forefoot skin defect. The flap was based on the distal end of the medial plantar artery and had distal anastomosis with the lateral plantar artery and dorsal metatarsal artery.</p><p><b>RESULTS</b>The flap was used clinically in 6 cases. The size of the flap ranged from 4 x 3 cm to 11 x 9 cm. The pedicle of the flap was 6 to 11 cm. All flaps survived completely. The aesthetic and functional results were satisfactory after 6-24 months follow-up.</p><p><b>CONCLUSION</b>The flap is one of the best choices for repairing of forefoot skin defects.</p>

Clinical application of reversed saphenous neurocutaneous vascular flap pedicle with the perforating branches of the tibialis posterior artery / 中华显微外科杂志

Objective To report the improved operative technique and clinical results of reversed saphenous neurocutaneous vascular flap. Method Under the guidance of Doppler flowmeter,a reversed saphenous neurocutaneous vascular flap pedicle with the perforating branches of the tibialis posterior artery were designed to repair the skin defects of the middle and lower leg,the ankle and the foot. Results The modified flaps were applied in 7 cases,all flaps survived completely. The size of the flaps ranged from 15cm?8cm to 5cm?4cm,the location of the perforating branches were 8～20 cm above the medial malleolus. The colour and texture of the flaps were excellent,the outline and functional results were satisfactory after 6～18 months follow up. Conclusions The flap is easy to design and dissect,blood supply is reliable,it is suitable for repairing the soft tissue defects of the middle and lower leg,the ankle and the foot. It is a new type of flap combining the neurocutaneous vascular flap with the perforator flap.

Clinical application of posterior neurocutaneous vascular axial flap in the forearm pedicle with dorsal branch of anterior interossea vessel / 中华显微外科杂志

Objective To report the improved operative technique and clinical results of posterior neurocutaneous vascular axial flap in the forearm Methods A reversed posterior neurocutaneous vascular flap in the forearm pedicle with dorsal branch of anterior interossea vessel were designed to repair the skin defects of hand and wrist Results The modified flaps were applied in 8 cases,all flaps survived completely The colour and texture of flaps were good,the outline and functional results were satisfactory after 6～12 months follow up Conclusion This type of flap is easy to dissect,blood supply is reliable,and major vessels in the forearm is preserved,It is suitable for repairing large skin and soft tissue defects of first web, dorsal aspects of wrist and palmar
