The place of the cross-leg flap in reconstructive surgery of the lower leg and foot: a review of 165 cases.

In a series of 165 cross-leg flaps, 94 per cent were successful. Some degree of necrosis occurred in almost half of them. Major necrosis requiring split-skin grafting occurred in less than one-fifth. Thrombo-embolic complications were rare and mainly in the older age group. The retunr of sensation was good; better in the flap than in the donor site. The long-term results were good with a low complication rate. On weight-bearing surfaces the cross-leg flap skin stands up well to wear and tear.     

Multicenter Evaluation of the Solana Group A Streptococcus Assay: Comparison with Culture

We compared group A Streptococcus (GAS) culture with a rapid helicase-dependent amplification (HDA) method using 1,082 throat swab specimens. The HDA method demonstrated 98.2% sensitivity and 97.2% specificity. GAS prevalence by culture was 20.7%, and it was 22.6% using the HDA method. In 35 min, the HDA method provided rapid, sensitive GAS detection, making culture confirmation unnecessary.
