METHODS
A 21-year-old woman reported no serious previous illness. For 3 days before admission she had a fever, headache and joint pains. She had become progressively more jaundiced. Physical examination was normal except for enlarged liver and spleen, swollen lymph nodes and facial
BACKGROUND
Manganese regulates many enzymes and is essential for normal development and body function. Chronic manganese intoxication has an insidious and progressive course and usually starts with complaints of headache, fatigue, sleep disturbances, irritability and emotional instability. Later,
Manganese (Mn) poisoning, a well-known hazard in miners and industrial workers, shares many features with Parkinson's disease. Two young agricultural workers with a parkinsonian syndrome, who mentioned exposure to the fungicide maneb (manganese ethylene-bis-dithiocarbamate), led us to investigate a
METHODS
The administration of trace elements is thought to be needed in patients receiving long-term parenteral nutrition. Recently, manganese intoxication or deposition was documented in such patients. We report two cases of manganese intoxication during intermittent parenteral nutrition including
OBJECTIVE
To analyze the importance attributed to manganese (Mn) in the health-disease-death process and possibilities for participation in risk management of women from two communities who live near the plant in the Molango mining district.
METHODS
Qualitative study based on 6 focus groups with
OBJECTIVE
To compare the levels of trace elements and heavy metal in patients with acute migraine and healthy controls.
METHODS
The prospective study was conducted at Yuzuncu Yil University, Turkey, from May to July 2013, and comprised migraine patients and an equal number of healthy controls.
BACKGROUND
Although adverse neuropsychological and neurological health effects are well known among workers with high manganese (Mn) exposures in mining, ore-processing and ferroalloy production, the risks among welders with lower exposures are less well understood.
METHODS
Confined space welding in
The Workplace Safety and Health Branch initiated a proactive study in the welding industry in Manitoba. Eight welding companies participated in this study. Health concerns raised by welders were welders' flash, sore/red/teary eyes, headaches, nosebleeds, and a black mucous discharge from their nasal
Welding fume contains manganese (Mn) which is known to be bio-available to and neurotoxic for the central nervous system. Although an essential metal, Mn overexposure may cause manganism, a parkinsonian syndrome. The present welder study sought to improve the clinical portrait of manganism and to
Patients receiving long-term parenteral nutrition (PN) with trace elements (TE) may exhibit T (1) shortening in the anterior pituitary gland and basal ganglia. The purposes of this study were to clarify at what time or from what site the signal change begins in children. Retrospective analysis of
Hypermanganesemia has recently been reported in long-term home parenteral nutrition patients receiving routine trace element supplementation. Because the regulation of manganese involves intestinal absorption and biliary excretion, patients receiving parenteral nutrition, especially those with
Manganese is a trace element and a cofactor of many enzymes, so it is essential for physiologic functioning, but it is also a neurotoxin at high doses. Manganism is most often caused by occupational exposure. It is manifested by a myriad of signs and symptoms ranging from the neurasthenia syndrome,
Pesticides can cause gene mutations and chromosomal aberrations in exposed individuals. We have investigated 24 workers exposed to pesticides. Clinical examinations and cytogenetic and toxicological tests were performed. Ten non-exposed individuals were used as controls. Toxicological dosages of
BACKGROUND
Inhalational exposure to metal-containing fumes generated by welding and related processes may result in the development of the clinical syndrome known as "metal fume fever." Polymer fume fever is a separate and distinct but related disorder that has been associated with inhalational
BACKGROUND
Manganese is known to cause a parkinsonian syndrome similar clinically to Parkinson disease (PD). L-Dopa responsiveness is a hallmark of PD; however, L-dopa's effect on manganese-induced parkinsonism is not well defined.
OBJECTIVE
To access the efficacy and safety of L-dopa therapy in a
