Materials and Methods: Confidential interviews were used to collect information from charm needle wearers. Two attempts at surgical removal of charm needles were carried out. Charm needle samples were chemically analyzed using EPMA method. A review of literature on the possible complications of charm needles in relation to MRI was made. Results: Patients had varied reasons for wearing charm needles including to be physically attractive, to overcome personal problems and for protection. Charm needles were made of gold alloy consisting of gold (85.2%-88.6%), copper (9.3%-10.8%) and trace elements of aluminium and silver. As such, MRI may not be a hazard to charm needle wearers given the fact that gold is non-ferromagnetic. However, artefacts may potentially distort the MR imaging. Conclusion: A tactful manner in handling these patients may be to ignore the needles unless a clinical need warrants intervention. The surgical removal of these needles may be a straightforward procedure, but the localization is usually a challenging task. At present, the pertinent literature does not contain carefully controlled studies that demonstrate the absolute safety of charm needle exposure to powerful magnetic fields.展开更多

The company will rely on existing businesses as its growth engine while overseas asset purchases and takeovers are just one aspect of the overall strategy, Chairman Fu Chengyu said after the annual general meeting in Hong Kong on May 29. CNOOC in 2005 failed in an $18.5 billion bid to buy Unocal Corp because of opposition by US lawmakers. The company is targeting the Caspian Sea, Africa and the Asia-Pacific region for future acquisitions. Based on the media reports, the oil producer is in talks with Talisman Energy Inc for an asset purchase or a takeover, but it is not confirmed by the company.展开更多
