El regulador de transmembrana de fibrosis quística (CFTR) disfuncional y sus efectos extrapulmonares

El daño del regulador de transmembrana de fibrosis quística (CFTR) puede causar una enfermedad grave fuera de los pulmones. El canal de cloruro (Cl-) ha sido el más estudiado, sin embargo, el bicarbonato (HCO3 -) tiene un rol muy importante en el comportamient...

Alcalosis respiratoria grave, la transformación de un cuadro funcional en orgánico. Caso clínico

Rev. méd. Chile; 150 (4), 2022
Severe respiratory alkalosis is a life-threatening condition, as it induces hypo- calcaemia and extreme adrenergic sensitivity leading to cerebral and myocardial vasoconstriction. We report a 37-year-old woman with previous consultations for a conversion disorder. While she was infected with SARS-CoV-2 (...

Concordance analysis between dosed serum bicarbonate and that calculated by gas analysis in chronic renal patients

J. bras. nefrol; 42 (4), 2020
Abstract Introduction: The control of metabolic acidosis in dialysis patients focuses on the supply of bicarbonate during the dialysis session, and it is not standard in all hemodialysis to assess serum bicarbonate concentrations. Bicarbonate expressed in blood gas analysis is the most sensitive standar...

Cetoacidosis por estrés: caso clínico en paciente con atrofia muscular espinal

Rev. méd. Chile; 148 (6), 2020
Spinal muscular atrophy is an uncommon cause of ketoacidosis, where there is a decrease in muscle mass, an abnormal metabolism of glucose and fatty acids, and changes in neuroendocrine function. These conditions favor the accumulation of keto acids and the development of metabolic acidosis. We report a 2...

Brazilian Dialysis Census: analysis of data from the 2009-2018 decade

J. bras. nefrol; 42 (2), 2020
ABSTRACT Introduction: National data on chronic dialysis treatment are essential for the development of health policies that aim to improve patient treatment. Objective: To present data from the Brazilian Society of Nephrology on patients with chronic dialysis for kidney disease in July 2018, making ...

Metabolic and volume status evaluation of hemodialysis patients with and without residual renal function in the long interdialytic interval

J. bras. nefrol; 41 (4), 2019
Abstract Introduction: It is unclear whether residual renal function (RRF) in dialysis patients can attenuate the metabolic impact of the long 68-hour interdialytic interval, in which water, acid, and electrolyte accumulation occurs. Objective: to evaluate serum electrolyte levels, water balance, and a...

Possible association between dysnatremias and mortality during hospitalization in patients undergoing acute hemodialysis: analysis from a Peruvian retrospective cohort

J. bras. nefrol; 41 (4), 2019
Abstract Objective: To evaluate the association between dysnatremias or dyschloremias and mortality during hospitalization in patients with acute kidney injury (AKI) or chronic kidney disease (CKD) undergoing acute hemodialysis. Methods: We carried out a retrospective cohort study on adult patients und...

Cambios estructurales de la superficie dental erosionada pre y post tratamiento con bicarbonato de arginina y monofluorofosfato de sodio: estudio piloto

Acta odontol. venez; 57 (1), 2019
La erosión dental se define como la pérdida patológica, crónica e indolora de los tejidos dentales, por la acción química de ácidos no producidos por la microflora bacteriana bucal. Los estadíos más avanzados pueden generar diferentes niveles de desgaste y producir hipersensibilidad destinaria. ...

Acidosis láctica asociada a metformina: caso clínico

Rev. méd. Chile; 145 (8), 2017
Metformin-associated lactic acidosis is a severe and infrequent adverse event. Early diagnosis is essential to start an early treatment, which often has favorable results. We report a 56 years old non-insulin-requiring type 2 diabetic female who developed a severe metabolic acidosis associated with metfo...

Anesthesia of Epinephelus marginatus with essential oil of Aloysia polystachya: an approach on blood parameters

An. acad. bras. ciênc; 89 (1,supl), 2017
ABSTRACT This study investigated the anesthetic potential of the essential oil (EO) of Aloysia polystachya in juveniles of dusky grouper (Epinephelus marginatus). Fish were exposed to different concentrations of EO of A. polystachya to evaluate time of induction and recovery from anesthesia. In the secon...
