Lead toxicity with a new focus: Addressing low-level lead exposure in Canadian children

Low level exposure to lead.

Only five people had used condoms on every occasion and eight people had not used them at all. In my clinic I have been asking girls who have had sex with strangers abroad how often they were able to persuade their partners to use condoms-or even withdrawal. I have so far reached zero out of seven. Although all the girls had asked the men to use condoms, they had refused, and the girls, all of ...

Perspective on Low Level Lead Toxicity

Cavitation (volume oscillations and collapse of gas bubbles), as generated by a co-administration of shockwaves (SW) and microbubbles (SWB), induces cytotoxicity in vitro. Moreover, cavitation potentiates the effects of Fluorouracil (FUra) on colon cancer cells. We aimed at reproducing such effects in vivo. A peritoneal carcinomatosis was induced in BDIX rats by intraperitoneal (IP) injection o...

Low level lead exposure and the development of children.

The clinical picture of childhood lead poisoning has changed dramatically over the past 20 years. Acute symptomatic lead poisoning, once a common problem, is now a rare event. Lead encephalopathy is even rarer. Most pediatric residents will not see a case of acute plumbism during their training; few will encounter the problem in their career. At the same time, epidemiologic studies from around ...

Exposure to lead in children--how low is low enough?

Encephalopathy in childhood due to lead poisoning was described more than 100 years ago, and cognitive sequelae after recovery were reported in 1943. During the past three decades, epidemiologic studies have demonstrated inverse associations between blood lead concentrations and children’s IQs at successively lower lead concentrations. In response, the Centers for Disease Control and Prevention...
