Abstract
For the medical practice, our manuscript acts as a signal, despite only presenting three cases which feature the association between hepatocytolysis, haemolysis and hypermagnesaemia. This clinical–biologic triad was highlighted with the workers who through the nature of their profession were exposing themselves periodically to vapours which contained copper sulphate neutralised with calcium hydroxide, a fungicide used for fruit trees. We are exclusively assessing the haematological perturbation. In this aetiological context, the generating mechanism for haemolysis is very probable biochemical, where hypercupraemia interferes with cellular antioxidant defence mechanisms. Hypothetically, the role of the redox homeostasis disorder in the intravascular destruction of erythrocytes is sustained, and particularly the coexistence of cell cytolysis in the medullary erythroid compartment, which can be assimilated with a possible ineffective erythropoiesis.

Abstract
The kidneys are famously responsible for maintaining external balance of prevalent minerals, such as sodium, chloride, and potassium. The kidney's role in handling trace minerals is more obscure to most nephrologists. Similarly, the impact of kidney failure on trace mineral metabolism is difficult to anticipate. The associated dietary modifications and dialysis create the potential for trace mineral deficiencies and intoxications. Indeed, there are numerous reports of dialysis-associated mishaps causing mineral intoxication, notable for the challenge of assigning causation. Equally challenging has been the recognition of mineral deficiency syndromes, amid what is often a cacophony of multiple comorbidities that vie for the attention of clinicians who care for patients with chronic kidney disease. In this paper, I review a variety of minerals, some of which are required for maintenance of normal human physiology (the U.S. Food and Drug Administration's list of essential minerals), and some that have attracted attention in the care of dialysis patients. For each mineral, I will discuss its role in normal physiology and will review reported deficiency and toxicity states. I will point out the interesting inter-relationships between several of the elements. Finally, I will address the special concerns of aluminum and magnesium as they pertain to the dialysis population.

Abstract
Several drugs and other compounds can induce acute and/or chronic nephrotoxicity. The goal of this study was to review clinical features of nephrotoxicity induced by 'atypical' or 'unconventional' agents, such as environmental agents (metals, minerals, animals), food agents (mushrooms, aristolochic acid, medicinal traditional herbals, dietary supplements, melamine), drugs, and other products (ethylene glycol). Nephrotoxicity varies according to local background, dependent on different food and cultural customs, as well as to differences in local fauna and flora. The incidence of such a phenomenon is not well known. Many different pathophysiological pathways are involved, and the spectrum of renal lesions is rather wide. 'Epidemic nephrotoxicity' may occur, as recently illustrated by the melamine epidemics in Chinese infants receiving powdered milk formulas; a rapid reaction to unusual increased frequency of acute kidney injury and nephrolithiasis in young children has led to a rapid analysis from international experts, with subsequent recommendations for diagnosis and care. Nephrotoxicity should be considered when there is any unexplained renal impairment, especially in children.

Abstract
Asia, the largest continent in the world, is heterogeneous in the ethnic, socioeconomic, and developmental status of its populations. A vast majority of it is poor with no adequate access to modern health care, making an accurate estimation of the nature and extent of acute kidney injury (AKI) difficult. Community-acquired AKI in otherwise healthy individuals is common, and the population developing AKI is younger compared with its counterparts in Europe or North America. The etiologic spectrum varies in different geographic regions of Asia depending on environmental, cultural, and socioeconomic factors. Some of the etiologic factors include AKI in relation to infectious diseases, intravascular hemolysis caused by glucose 6-phosphate dehydrogenase deficiency, poisonings caused by industrial chemicals or copper sulphate, animal venoms, natural medicines, heat stroke, and after complications of pregnancy. Preventive opportunities are missed because of failure to recognize the risk factors and early signs of AKI. Patients often present late for treatment, leading to multi-organ involvement and increased mortality. The exact etiologic diagnosis cannot be established in many instances because of a lack of appropriate laboratory support. Modern methods of renal replacement therapy are not universally available; and intermittent peritoneal dialysis is still widely practiced in many areas.

Abstract
Severe Acute Copper Sulphate Poisoning: A Case ReportAs copper sulphate pentahydrate (CSP) is a common compound used in agriculture and industry, chronic occupational exposures to CSP are well known, but acute poisoning is rare in the Western world. This case report describes acute poisoning of a 33-year-old woman who attempted suicide by ingesting an unknown amount of CSP. On admission to the hospital, she had symptoms and signs of severe hemorrhagic gastroenteritis, dehydration, renal dysfunction and methaemoglobinaemia with normal serum copper level. Therapy included early gastric lavage, fluid replacement, vasoactive drugs, furosemide, antiemetic drugs, ranitidine, and antidotes methylene blue and 2,3-dimercaptopropane-1-sulphonate (DMPS). However, the patient developed severe intravascular haemolysis, acute severe hepatic and renal failure, as well as adrenal insufficiency. After prolonged, but successful hospital treatment, including haemodialysis and IV hydrocortisone, the patient was discharged with signs of mild renal and liver impairment. Our conclusion is that in severe cases of copper poisoning early supportive measures are essential. In addition, antidotes such as methylene blue for methaemoglobinaemia and chelating agent such as DMPS improve morbidity and survival of severely poisoned victims.

Abstract
We report a case of chronic copper poisoning in a flock of 182 grazing dairy sheep in Thessaly, Central Greece. Five ewes were found dead during the course of a week. The diagnosis of copper poisoning was confirmed by necropsy examination, blood test results, and abnormally high copper levels in liver and kidney samples. A field investigation revealed the source of copper as a litter heap from a broiler farm to which the sheep had accidental access during their movement between the milking parlour and the grazing area. Access to the litter was subsequently blocked and all sheep were provided with 50 g of a salt/gypsum/sodium molybdate mixture (90.0: 9.8: 0.2, w/w) mixed in 500 g of concentrate feed daily, for a period of 5 weeks. Follow-up blood samples were taken 3 and 8 wk after the initial diagnosis. A reduction in aspartate aminotransferase activity indicated the source of copper had been eliminated and the subsequent treatment was successful.

Abstract
Aquaporin-3 (AQP3) is an aquaglyceroporin expressed in erythrocytes and several other tissues. Erythrocytes are, together with kidney and liver, the main targets for copper toxicity. Here we report that both water and glycerol permeability of human AQP3 is inhibited by copper. Inhibition is fast, dose-dependent, and reversible. If copper is dissolved in carbonic acid-bicarbonate buffer, the natural buffer system in our body, doses in the range of those observed in Wilson disease and in copper poisoning caused significant inhibition. AQP7, another aquaglyceroporin, was insensitive to copper. Three extracellular amino acid residues, Trp128, Ser152, and His241, were identified as responsible for the effect of copper on AQP3. We have previously shown that Ser152 is involved in regulation of AQP3 by pH. The fact that Ser152 mediates regulation of AQP3 by copper may explain the phenomenon of exquisite sensitivity of human erythrocytes to copper at acidic pH. When AQP3 was co-expressed with another AQP, only glycerol but not water permeability was inhibited by copper. Our results provide a better understanding of processes that occur in severe copper metabolism defects such as Wilson disease and in copper poisoning.
