Magnesium and Health
2019
Magnesium (Mg) is the second most abundant cation after potassium in the intracellular compartment and has a critical role in modulating a large variety of cellular activities and metabolic pathways. Mg is cofactor in over 300 enzymatic reactions including all reactions that involve ATP utilization and transfer [1,2]. Over the past decades, the clinical relevance of Mg and its impact on health has been documented. In the human body, around 24 grams (1 mole) of Mg are present. Less than 1% of total Mg is in the serum; normal serum Mg concentrations range between 0.75-0.95 mmol/L (1.7-2.5 mg/dL or 1.5-1.9 meq/L). In healthy adults, daily Mg requirement is around 300-400 mg (5 to 6 mg/kg/day) …
Isolated dissection of the superior mesenteric artery: a case report and literature review
2014
Isolated dissection of the superior mesenteric artery is rare; it is predominantly observed in men with the highest incidence in those over 40 years old. Contrast-enhanced multi-detector computed tomography is considered essential for the diagnosis, therapeutic management and follow-up. The therapeutic approach ranges from conservative medical treatment to surgery or endovascular stent placement, but there are, to date, no approved guidelines. We report the case of a 68-year old man who entered our Emergency Department just for mild abdominal pain, which later proved to be due to acute dissection of the superior mesenteric artery.
Management of high blood pressure in children and adolescents: recommendations of the European Society of Hypertension.
2009
Hypertension in children and adolescents has been gaining ground in cardiovascular medicine, mainly due to the advances made in several areas of pathophysiological and clinical research. These guidelines arose from the consensus reached by specialists in the detection and control of hypertension in children and adolescents. Furthermore, these guidelines are a compendium of scientific data and the extensive clinical experience it contains represents the most complete information that doctors, nurses and families should take into account when making decisions. These guidelines, which stress the importance of hypertension in children and adolescents, and its contribution to the current epidemi…
Review article: Chronic constipation and food hypersensitivity--an intriguing relationship.
2006
Summary Background Chronic constipation is common in the general population. Some studies have shown that in children cow's milk protein hypersensitivity can cause chronic constipation unresponsive to laxative treatment. Aims To review the literature and summarize the data that point to a relationship between refractory chronic constipation and food hypersensitivity, and to discuss the hypothesis that the pathogenesis of constipation due to food hypersensitivity. Methods A search in the U.S. National Library of Medicine was performed, matching the key words ‘chronic constipation, food intolerance and allergy’. Results Thirty-three papers were found but only 19 of them were related to the to…
Feasibility of the Allergy Questionnaire for Athletes (AQUA © ) in pediatric age
2018
A burden of respiratory and allergic symptoms up to almost 60% has been observed in young and adult athletes, influencing physical performances1 . The Allergy Questionnaire for Athletes (AQUA©) is a validated screening tool for the prediction of the atopic status in adult athletes2 ; it was recently tested in Belgian young elite athletes (12-14 years old)3 , but its actual feasibility and suitability for children and adolescent was not evaluated. Indeed, there is evidence that children are prone to employ "satisficing" response strategies, answering every question positively/negatively, or simply not answering4 . Therefore, the present cross-sectional survey was carried out to assess feasib…
Is there a role for antileukotrienes in urticaria?
2006
In vitro and in vivo clinical and experimental data have suggested that leukotrienes play a key role in inflammatory reactions of the skin. Antileukotriene drugs, i.e. leukotriene receptor antagonists and synthesis inhibitors, are a new class of anti-inflammatory drugs that have shown clinical efficacy in the management of asthma. We searched the MedLine database and carried out a manual search on journals specializing in allergy and dermatology for the use of antileukotriene drugs in urticaria. Montelukast might be effective in chronic urticaria associated with aspirin or food additive hypersensitivity or with autoreactivity to intradermal serum injection when taken with an antihistamine b…
Food allergy in gastroenterologic diseases: Review of literature
2007
Food allergy is a common and increasing problem worldwide. The newly-found knowledge might provide novel experimental strategies, especially for laboratory diagnosis. Approximately 20% of the population alters their diet for a perceived adverse reaction to food, but the application of double-blind placebo-controlled oral food challenge, the “gold standard” for diagnosis of food allergy, shows that questionnaire-based studies overestimate the prevalence of food allergies. The clinical disorders determined by adverse reactions to food can be classified on the basis of immunologic or nonimmunologic mechanisms and the organ system or systems affected. Diagnosis of food allergy is based on clini…
Helicobacter pylori first-line and rescue treatments in patients allergic to penicillin: Experience from the European Registry on H pylori management…
2020
Background Experience in Helicobacter pylori eradication treatment of patients allergic to penicillin is very scarce. A triple combination with a PPI, clarithromycin (C), and metronidazole (M) is often prescribed as the first option, although more recently the use of a quadruple therapy with PPI, bismuth (B), tetracycline (T), and M has been recommended. Aim To evaluate the efficacy and safety of first-line and rescue treatments in patients allergic to penicillin in the "European Registry of H pylori management" (Hp-EuReg). Methods A systematic prospective registry of the clinical practice of European gastroenterologists (27 countries, 300 investigators) on the management of H pylori infect…
Sonographic demonstration of a spontaneous rectus sheath hematoma following a sneeze: a case report and review of the literature
2020
Spontaneous rectus sheath hematoma (SRSH) is an uncommon cause of acute abdominal pain characterized by bleeding within the rectus sheath; it is a benign condition and, in most cases, it is treated conservatively. Bleeding of the abdominal wall is an unusual condition that is quite challenging to identify promptly and can be easily overlooked during a routine physical examination. In daily practice, anticoagulant therapy is one of the main risk factors for hemorrhagic events. In this respect, we report a rare case of spontaneous hematoma of the abdominal wall (diagnosed and monitored through an ultrasound examination) that arose after sneezing in a patient receiving anticoagulant treatment.
Surveillance for hepatocellular carcinoma with a 3-months interval in “extremely high-risk” patients does not further improve survival
2022
Abstract Background An enhanced surveillance schedule has been proposed for cirrhotics with viral etiology, who are considered at extremely high-risk of hepatocellular carcinoma (HCC). Aims We compared the 3- and 6-months surveillance interval, evaluating cancer stage at diagnosis and patient survival. Methods Data of 777 HBV and HCV cirrhotic patients with HCC diagnosed under a 3-months (n = 109, 3MS group) or a 6-months (n = 668, 6MS group) surveillance were retrieved from the Italian Liver Cancer database. Survival in the 3MS group was considered as observed and adjusted for lead-time bias, and survival analysis was repeated after a propensity score matching. Results The 3-months surveil…
