Based on toxicological, clinical, and epidemiological knowledge, the present paper reviews the status regarding possible deleterious health effects from occupational exposure to metallic mercury (Hg) in dental practice. Symptoms from the central nervous system are among the health problems that most often are attributed to Hg exposure in dentists and dental nurses working with amalgam. Uncharacteristic symptoms of chronic low-level Hg vapor exposure including weakness, fatigue, and anorexia have been observed in numerous studies of dental personnel...

Mercury poisoning is a rare but fatal toxicologic emergency. Neurologic manifestations involving the central nervous system are seen usually with chronic mercury intoxication. The most commonly seen complaints are headache, tremor, impaired cognitive skills, weakness, muscle atrophy, and paresthesia. Here, we present a male patient who was chronically exposed to elemental mercury and had papilledema and intracranial hypertension without parenchymal lesion in the central nervous system. A 12-year-old male patient was referred to our emergency room because of severe fatigue, generalized muscle pain and weakness, which was present for a month...

UNLABELLED: Mercury is a heavy metal found in nature in three forms: metallic mercury, organic and inorganic compounds. It is a general protoplasmatic toxin. The pathophysiology of mercury toxicity is related to its binding to sulfhydryl groups of different receptor proteins and cellular enzymes, interrupting cellular metabolism and in this way causing cell death. In the paper we present a case of 57-year-old woman, who was admitted due to suspicion of metallic mercury parenteral poisoning...

Munchausen syndrome by proxy is a kind of child abuse in which affected children are often hospitalized for long periods and endure repetitive, painful and expensive diagnostic attempts. We present herein two toxicologically confirmed cases of Munchausen syndrome by proxy. Case 1 is a 16-month-old male who had fever, peripheral cyanosis, tremor, and reported cardiac arrest. Symptoms recurred in the hospital when the mother administered fluids. Toxicology detected 3.5 ng/ml mercury (Hg) in the fluid and 9.4 microg Hg/g creatinine in the urine...

Acute mercury vapor poisoning is a rare but fatal toxicological emergency. People are exposed to mercury in daily life by the way of foods, vaccines, antiseptics, ointments, amalgam or occupation. We present here, the clinical picture and management of four members of the same family who were exposed to elemental mercury. Three of the family members were seen in another hospital with malaise, fever, eritematous rash and pulmonary problems. Their questioning revealed the mercury exposure. Having a suspicion of heavy metal intoxication, blood and urine mercury levels were measured and mercury intoxication was diagnosed...

Cinnabar has been an important traditional Chinese medicine as a sedative and soporific agent for more than 2000 years. It is a naturally occurring mercuric sulfide and containing more than 96% mercuric sulfide (HgS). There are about 10% -30% Chinese patent medicines containing cinnabar according to the Pharmacopoeia of China (2005). It's hard to deny that cinnabar has therapeutic effect in clinic practice. However, cinnabar's extraordinary high containing mercury makes people hesitate to use. Furthermore, the abuse of cinnabar, which caused intoxication cases, has been reported occasionally...

Because the toxicological effects of mercury (Hg) are more serious in the developing central nervous system of children than adults, there are growing concerns about prenatal and early childhood Hg exposure. This study examined postnatal methylmercury (MeHg) exposure and cognition and behavior in 780 children enrolled in the Treatment of Lead (Pb)-exposed Children clinical trial (TLC) with 396 children allocated to the succimer and 384 to the placebo groups. Mercury exposure was determined from analyses of blood drawn 1 week before randomization and 1 week after treatment began when succimer had its maximal effect on blood Pb (PbB)...

OBJECTIVE: To review the diagnosis and management of drug overdose and poisonings in a two-part presentation. DATA SOURCES: A review of articles reported on drug overdose and poisonings. SUMMARY OF REVIEW: In patients who attempt suicide it is usual for the overdose to be a therapeutic agent, although in the severely mentally disturbed patient the agent may be an unusual poison. As with any overdose, the most important aspects in the management is the maintenance of the patient's airway, ventilation and circulation, while the toxin is metabolised and excreted...

The effects of toxicant metals on human health have been reported in peer-reviewed literature with increasing frequency. Toxicant metals are present in many diseases of aging, especially vascular diseases. Toxicant metals are a natural environmental phenomenon as well as a byproduct of industrialization. The historical experience of toxicologists who treated individuals poisoned by acutely toxicant metals is waning; very few of these cases have been reported during the past 30 years in the US. Researchers with a special interest in clinical metal toxicology have noticed a clinical correlation between metal detoxification by chelation therapy and clinical improvement of vascular diseases...

In this review we used the published data on depleted uranium (experimental and epidemiological) from the current literature. Depleted uranium is a toxic heavy metal that in high dose may cause poisoning and health effects as those caused by lead, mercury, and chromium. It is slightly radioactive. The aim of this review was to select, to arrange, to present references of scientific papers, and to summarise the data in order to give a comprehensive image of the results of toxicological studies on depleted uranium that have been done on animals (including carcinogenic activity)...

Acute mercury vapor poisoning is an uncommon but potentially fatal toxicologic emergency. A case series is presented of a family who became exposed to mercury vapor as a result of home gold ore processing. The severity of the poisoning necessitated mechanical ventilation in three of the eight patients who were exposed. Despite aggressive management, two patients died, because their clinical course was dominated by irreversible pulmonary toxicity. The remaining survivors developed varying degrees of mercury toxicity...

Four case reports are presented of patients who ate the meat of a hog inadvertently fed seed treated with fungicides containing ethyl mercury chloride. The clinical, electrophysiological, and toxicological, and in two of the patients the pathological data, showed that this organic mercury compound has a very high toxicity not only for the brain, but also for the spinal motoneurones, peripheral nerves, skeletal muscles, and myocardium.
