RESUMEN

Dipyrone (metamizole) is well-known for its powerful effect with central and peripheral activity. This meta-analysis involved articles published between 1973 and 2021, revealing that Brazil is the country which most published scientific articles relating the use of dipyrone in dogs, and this drug is widely recommended as an analgesic to control pain in cases of postoperative and cancer. Dipyrone is one of the favorite drugs used in small animal clinic in Brazil, and 12 commercial brands are available to use in dogs at doses among 25 to 50mg/kg for oral, intravenous and intramuscular administration. The effects of dipyrone may be potentiated when used in combination with other analgesic agents such as tramadol. In several studies, the occurrence of vomiting has been observed as an adverse effect, especially when the drug is used during surgical procedures, but metamizole has presented a low potential to cause gastric ulceration. The meta-analysis study of the use of dipyrone in dogs shows the clinical importance of this drug in Brazil, being an effective and safe medication, as long as it is used in the indicated dose of 25 mg/kg.(AU)

RESUMEN

A novel analytical approach involving an improved rotating-disk sorptive extraction (RDSE) procedure and ultra-high-performance liquid chromatography (UHPLC) coupled to an ultraspray electrospray ionization source (UESI) and time-of-flight mass spectrometry (TOF/MS), in trap mode, was developed to identify and quantify four non-steroidal anti-inflammatory drugs (NSAIDs) (naproxen, ibuprofen, ketoprofen and diclofenac) and two anti-cholesterol drugs (ACDs) (clofibric acid and gemfibrozil) that are widely used and typically found in water samples. The method reduced the amount of both sample and reagents used and also the time required for the whole analysis, resulting in a reliable and green analytical strategy. The analytical eco-scale was calculated, showing that this methodology is an excellent green analysis, increasing its ecological worth. The detection limits (LOD) and precision (%RSD) were lower than 90ng/L and 10%, respectively. Matrix effects and recoveries were studied using samples from the influent of a wastewater treatment plant (WWTP). All the compounds exhibited suppression of their signals due to matrix effects, and the recoveries were approximately 100%. The applicability and reliability of this methodology were confirmed through the analysis of influent and effluent samples from a WWTP in Santiago, Chile, obtaining concentrations ranging from 1.1 to 20.5µg/L and from 0.5 to 8.6µg/L, respectively.

RESUMEN

After beta lactam antibiotics, hypersensitivity reactions to nonsteroidal antiinflammatory drugs are the second cause of hypersensitivity to drugs. Acute manifestations affect the respiratory tract (aspirin exacerbated respiratory disease), the skin (urticaria and angioedema), or are generalized (anaphylaxis). Correct diagnosis and treatment in order to prevent unnecessary morbidity and the potential risk of death from these severe reactions, and to provide proper medical advice on future drug use frequently requires the participation of allergology specialists familiar with these clinical conditions.

RESUMEN

Necrotizing gastritis is an infrequent severe pathology. The rich vascular supply and intramural arterial anastomosis protects stomach from vascular disease and embolism. Gastric infarction and necrosis presents as an acute abdominal emergency that requires rapid resolution, which in general includes surgery. Other important etiologies reported are chemical agents, mechanical distention, postoperative, bulimia and infectious diseases. In this article, we report a case of necrotizing gastritis in a 29 years-old male patient, with chronic consumption of NSAIDs for low back pain. He was admitted in the emergency room due to acute abdominal pain that appeared, after alcohol and raw fish consumption. Antral wall thickening was observed in the abdominal computed tomography. Upper gastric endoscopy showed necrosis of antral mucosa and biopsies confirmed necrotizing gastritis. He received medical therapy with antibiotics and proton pump inhibitors with an excellent response with clinical and endoscopic resolution in one month.

La gastritis necrotizante es una patología infrecuente muy grave. Esto se debe en parte a la rica irrigación y a las anastomosis arteriales intramurales que protegen al estómago de enfermedades vasculares y embolias. El infarto gástrico se presenta como una urgencia abdominal, que requiere resolución precoz, frecuentemente quirúrgica. Otras etiología importantes reportadas incluyen agentes químicos, factores mecánicos, bulimia e infecciones. En este artículo se presenta el caso de un paciente de 29 años, sexo masculino, con antecedentes de uso crónico de anti-inflamatorios no esteroidales (AINES), que ingresa a urgencia con dolor abdominal agudo, posterior al consumo de alcohol y pescado crudo. Destaca un engrosamiento antral marcado, sin neumatosis en la tomografía computada de abdomen. En la endoscopia digestiva alta se observa extensa necrosis de la mucosa antral y se confirma el diagnóstico de gastritis necrotizante por biopsias. El paciente tuvo una excelente respuesta a tratamiento con reposo intestinal, antibióticos e inhibidores de bomba de protones. Luego de 1 mes, presentó recuperación completa clínica y endoscopía.
