The ceramics industry and lead poisoning. Lead poisoning in relation to technology and jobs.

The investigation evaluates the risk of lead absorption for 288 ceramics industry workers. Cases were studied in relation to sex, type and length of exposure, production plant characteristics, and jobs performed. The difference linked with sex was amplified by the fact that men usually performed the decidedly higher risk jobs, such as those connected with the direct use of ceramic glazes, in which--although to a variable extent--high percentages of lead are used. In fact, decreasing amounts of lead absorption were found for workers engaged in the operations of glazing, kiln work, maintenance and decoration, selection coming last. It was concluded that, in the Italian ceramics industry, lead exposure is linked to the use of lead-rich glazes and that this exposure may thus vary according to the different jobs or different technological cycles. Although female workers primarily carry out decoration and selection jobs, they nonetheless show high levels of lead in their blood, exceeding 1.9 mu mol/l--the limit currently recommended for women.

[Chronic lead poisoning: Lead gout with giant tophi on the skin, nephrophathy and porphyrinopathy].

Chronic lead nephtropathy, secondary gout (lead-gout) and porphyrinuria may develop after long lasting professional exposure to lead. A printer with giant tophi on his hands and feet excreted a significantly higher amount of lead after infusion of calcium EDTA in comparison with a normal control person. This result indicates an increased mobilization of lead from skeletal deposits. Furthermore, the laboratory findings showed renal insufficency and porphyrinuria up to 1316 mug/l (elevation of total porphyrins with slight or no elevation of delta-amino-levulic acid and porphobilinogene). The clinical triad nephropathy, secondary gout and porphyrinuria seems to be a variant of chronic lead poisoning.

Childhood lead poisoning.

Lead poisoning has been referred to as the most important environmental health hazard for children in New England. Medical professionals are in a unique position to perform a number of interventions that could make a lasting impact. First, physicians and nurses, particularly in the areas of pediatrics and family medicine, can provide anticipatory guidance to all families with young children. Lead poisoning, in contrast to long held beliefs, is an affliction that affects all socioeconomic groups. Parents should thus be informed regarding sources of lead, including occupational and hobby sources, and basic nutritional and abatement information should be provided. Second, health care workers should encourage lead screening in appropriately aged children at recommended intervals based on known risk factors. Once a blood lead concentration greater than 20[symbol: see text]g/dl has been obtained in a child, treatment or referral to an established lead clinic should be undertaken in a timely fashion. For children with low or moderate lead levels, many pediatricians or family physicians prefer to supervise their patients' treatment, including chelation therapy. For children with higher levels or in instances when the health care professional elects to refer, there are several lead clinics throughout New England whose clinicians are experienced in the treatment of childhood lead poisoning. Finally the medical profession needs to publicly recognize, as child advocates, that lead poisoning is one of the most common pediatric health problems in the United States and that it is entirely preventable. Fortunately, after many years and much hard work, Rhode Island finally has laws that start to deal with the lead problem in an appropriately aggressive fashion.(ABSTRACT TRUNCATED AT 250 WORDS)

The gastrointestinal manifestations of gunshot-induced lead poisoning.

Lead poisoning associated with gunshot is not unknown but, unless suspected, can be easily missed. We describe a patient with lead intoxication following a gunshot injury, who presented with abdominal colic, anorexia, and weight loss as initial manifestations. He had extremely high blood lead levels and the onset of lead poisoning was comparatively rapid. We review the recent English language literature (1980-1993) related to lead poisoning due to lead projectiles with particular emphasis on mechanisms responsible for its gastrointestinal manifestations.

Lead poisoning.

Lead poisoning is the most common disease of environmental origin in the United States today. Adult lead poisoning results primarily from exposure by inhalation in the workplace. Pediatric lead poisoning results principally from the ingestion of lead from environmental media, including paint chips, dust, soil, drinking water, ceramics, and medications. Lead is toxic to many organ systems, among them developing erythrocytes, the kidneys, and the nervous system. Lead-induced toxicity to the central nervous system causes delayed development, diminished intelligence, and altered behavior. In young children, this effect has been demonstrated convincingly to occur at blood lead levels between 10 and 20 micrograms per dl. The Centers for Disease Control and Prevention has recommended that a blood lead level of 10 micrograms per dl or higher be considered evidence of increased lead absorption, and the National Academy of Sciences has concurred in that recommendation. Unresolved issues in need of further study include the frequency of screening young children for lead, the question of whether women should be offered screening for lead before conceiving a pregnancy, the role of x-ray fluorescence analysis in assessing lead in bone, and the appropriate legislative response of the United States government to lead-based paint abatement.

Meso-2,3-dimercaptosuccinic acid in the diagnosis and treatment of lead poisoning.

Lead poisoning remains one of the hazards of industrialized civilization. CaNa2 EDTA and dimercaprol, the usual therapeutic measures, have many side effects and can be given by parenteral route alone. The authors present a case of chronic lead poisoning caused by ingestion of contaminated flour ground in a primitive flour mill. The diagnosis was confirmed by the CaNa2 EDTA provocative test. Dimercaptosuccinic acid (DMSA) was given orally as a further provocation and resulted in an 11-fold increase in urinary lead excretion. A 5-day course of treatment with DMSA was instituted, during which symptoms abated, urinary lead excretion increased and the blood lead level decreased. No side effects were noticed. There has been no relapse over several months of follow-up. The authors conclude that the oral use of DMSA is effective, safe and convenient both as a provocative test in establishing the diagnosis of lead poisoning and as a therapeutic tool.

Screening for chronic lead poisoning in lead factory workers.

One hundred and forty-nine lead factory workers comprising of 46 fume exposed, 78 handling lead materials and 25 controls were screened for chronic lead poisoning. Blood lead level was determined by atomic absorption spectrometery and urinary ALA by ion-exchange chromatography. Fume exposed workers had significantly higher (P < 0.01) blood lead (median 61.20 micrograms/dl, range 21.20-171.10 micrograms/dl) and urinary ALA levels (median 4.10 mg/l, range 01.0-22.9 mg/l) than workers handling lead materials and controls. Urinary ALA was found to be a more sensitive and specific test for lead poisoning than estimation of blood lead levels.

[Current diagnosis and treatment of lead poisoning].

Lead may be an industrial and an environmental hazard which becomes of greater importance every year. Classical symptoms of plumbism are rare, whenever minor clinical signs increase in frequency. Erythrocyte zinc protoporphyrin and delta-aminolaevulinic acid dehydratase are reliable indicators of the importance of the lead poisoning in individuals. The concentration of lead in blood is also a suitable biological indicator as is EDTA mobilization test. The treatment is based on the use of chelating agents such as calcium EDTA or DMSA, but the only solution is reduction or removal of the sources of lead exposure.

Art in relation to lead poisoning.

Lead poisoning is an ancient and modern problem. Since many artists have had exposure to lead, it is appropriate to use some of their works as a vehicle to depict the symptoms of the variable syndromes associated with lead exposure.

Pain in abdomen--do not forget lead poisoning.

Lead toxicity has been recognized for thousands of years, and is still around. We encountered 11 patients with lead toxicity in the last two years. All patients had presented with diffuse pain in the abdomen, anemia and mild derangements of liver biochemistry. History of intake of indigenous or herbal medicine for diabetes mellitus or psychosexual disorders was present in eight patients. All of them had elevated blood lead levels. Abdominal pain responded promptly to treatment with chelating agents.
