Fernwood Garden: Poisonous 5-leaf vine


Got several itchy rashes and minor blisters after ca. 36 hours upon contact. The vine is definitely poisonous causing contact dermatitis, yet I couldn't id it as poison ivy, oak or sumac, based on the pictures I can see on the web. So what is it? Can somebody help?
Update:
Well, I researched the web a bit harder and found a likeness of the above to drawings and pictures of the Virginia creeper (Parthenocissus quinquefolia), which has 5 leaves alright. The fruits of the Virginia creeper is known to contain oxalic acid, which is toxic when ingested, but the leaves and the sap?
