　　The Case of the Disappearing Fingerprints

　　One useful anti-cancer drug can effectively 51 the whorls and other characteristic marks that give people their distinctive fingerprints. Losing them could become troublesome. A case released online in a letter by Annals of Oncology indicates how big a problem of 52 fingerprints is.

　　Eng-HuatTan, a Singapore-based medical 53 describes a 62-year old man who has used capecitabine to treat his nasopharyngeal cancer. After three years on the 54 ,the patient decided to visit U. S. relatives last December. 55 he was stopped by U.S customs officials for 4 hours after entering the country when those officials couldn't get fingerprints from the man. There were no distinctive swirly 56 appearing from his index finger.

　　U. S. customs has been fingerprinting incoming foreign visitors for years, Tan says. Their index fingers are 57 and screened against digital files of the fingerprints of bad guys—terrorists and potential criminals that our federal guardians have been tasked with keeping out of the country. Unfortunately, for the Singaporean traveler, one potential 58 effect of his drug treatment is a smoothing of the tissue 59 the finger pads. Hence, no fingerprints.

　　"It is uncertain when fingerprint loss will begin to take place 60 patients who are taking capecitabine," Tan points out. So he cautions any physicians who prescribe the drug to provide their patients with a doctor's note 61 out that their medicine may cause fingerprints to disappear.

　　Eventually, the Singapore traveler made it into the United States. I guess the name on his passport didn't raise any red flags. But he's also now got the explanatory doctor's note—and won't leave home 62 it.

　　By the way, maybe the Food and Drug Administration, 63 approved use of the drug 11 years ago, should consider updating its list of side effects associated 64 this medicine. The current list does note that patients may experience vomiting, stomach pain and some 65 side effects. But no where does it mention the potential for loss of fingerprints.
