Gitelman syndrome (GS) is a rare autosomal recessive salt-losing tubulopathy. The incidence of Gitelman syndrome is 25 cases in 1 million among western population. This patient presented with loose stool, vomiting and sudden onset quadriparesis. Investigations revealed hypokalaemia, metabolic acidosis, hypomagnesaemia, hypocalciuria, hypermagnesuria. Symptoms and hypokalemia improved after starting oral magnesium and potassium supplements. But the patient again presented with symptomatic hypokalemia and delivered a still born foetus with hydrocephalus...

BACKGROUND: Epidemiological studies demonstrate an inverse association between serum magnesium and incidence of cardiovascular disease. Diuretics commonly cause hypomagneseamia. METHOD: We evaluated effects of magnesium supplementation on blood pressure (BP) and vascular function in thiazide-treated hypertensive women in a randomized, double-blind, clinical trial. Hypertensive women (40-65 years) on hydrochlorothiazide and mean 24-h BP at least 130/80 mmHg were divided into placebo and supplementation (magnesium chelate 600 mg/day) groups...

Disturbances in magnesium homeostasis are frequent clinical conditions, particularly the prevalence of hypomagnesaemia is high. However, it remains an open question which laboratory method is optimal to assess the magnesium level in the body. Most frequently physicians measure total magnesium in serum. Many associative data from observational studies point towards an association between low magnesium levels and increased cardiovascular risk as well as increased mortality. Vice versa, normal-to-high magnesium levels in patients with advanced renal failure translate to a better outcome...

Despite some advantages over traditional methods, Web-based studies elicit concerns about generalizability. To address this issue, we compared dietary intakes between an electronic (e-) cohort study and a nationally representative survey. We studied 49,443 French volunteers aged 18-74 years recruited during 2009-2010 in the NutriNet-Santé Study, a general population-based e-cohort study. The Etude Nationale Nutrition Santé (ENNS; 2006-2007), a cross-sectional study with a nationally representative sample of 2,754 French adults aged 18-74 years, served as the reference data set...

Hypertension is the most important, modifiable risk factor for cardiovascular disease and mortality. High salt intake may predispose children to develop hypertension later. A modest reduction in population salt intake worldwide would result in a major improvement in public health. Regarding smoking as another risk factor, there are various strategies that can be used to promote smoking cessation. Physicians are in an excellent position to help their patients stop smoking. Targeted weight loss interventions in population subgroups might be more effective for the prevention of hypertension than a general-population approach...

In a recent work we showed that magnesium (Mg(II)) plays an important role in industrial ethanol production, overcoming the negative effect of the excess of minerals, particularly copper, present in sugarcane juice, with a consequent increase in ethanol yield. This cation has been reported to be involved in several steps of yeast metabolism, acting mainly as a co-factor of several enzymes of fermentation metabolism and protecting yeast cells from stressful conditions. However, despite many physiological investigations, its effect in the molecular mechanisms that control such metabolic activities remains unclear and to date no information concerning its influence on gene expression has been provided...

While the diagnosis of migraine in children is generally straightforward, treatment can seem complex with a number of medication choices, many of which are used "off label." Patients with intermittent migraines can often be managed with ibuprofen or naproxen taken as needed. Unfortunately, by the time that children present to our practice, they have often tried these medications without improvement. Triptans are frequently prescribed to these patients with good success. It is important to make the patient aware of the possible associated serotonergic reactions...

BACKGROUND AND OBJECTIVES: Peroral supplementation with trivalent-chromium (Cr) or magnesium (Mg) has been shown to improve insulin resistance (IR). The objective of this study was to determine whether combined peroral supplementation with Cr and Mg improves IR more effectively than Cr or Mg alone. METHODS AND STUDY DESIGN: Subjects (n=120, age range 45-59 years old) and diagnosed with IR were randomly divided into four groups and monitored for a period of 3 months: group 1 (the placebo control group), group 2 (160 μg/d Cr), group 3 (200 mg/d Mg), and group 4 (160 μg/d Cr plus 200 mg/d Mg)...

: The use of medications that block gastric acid secretion, such as proton pump inhibitors, has rapidly escalated in the United States. Although originally intended for short-term treatment of specific conditions, PPIs have expanded to long-term use with unanticipated consequences, including mineral deficiencies related to lack of sufficient stomach acid needed for extraction of minerals from the foods and supplements ingested. Herein, the author reports on a case of a patient with tachycardia and other arrhythmias that had been resistant to the medications prescribed by a series of cardiologists...

Magnesium is the fourth most abundant cation in the human body and is the second most prevalent cation in intracellular tissues. Myocardial cell action potentials are mediated by voltage-dependent Na(+), K(+), and Ca(2+ )channels which, when their function is altered, can lead to the genesis of cardiac dysrythmias. Magnesium regulates the movement of ions through these channels within myocardial tissues. The potential ability of magnesium supplementation to prevent and/or treat arrhythmias has been recognized in clinical medicine for years...

Accumulating evidence suggests that hyperphenylalaninemia in phenylketonuria (PKU) can cause neuropsychological and psychosocial problems in diet-off adult patients, and that such symptoms improve after resumption of phenylalanine-restricted diet, indicating the need for lifetime low-phenylalanine diet. While limiting protein intake, dietary therapy should provide adequate daily intake of energy, carbohydrates, fat, vitamins, and microelements. We evaluated nutrient balance in 14 patients with classical PKU aged 4-38 years...
