Renal Tubular Acidosis
Significant bilateral nephrocalcinosis (calcification of the kidneys) on a frontal X-ray (radiopacities (white) in the right upper and left upper quadrant of the image), as seen in distal renal tubular acidosis. Renal tubular acidosis (RTA) is a medical condition that involves an accumulation of acid in the body due to a failure of the kidneys to appropriately acidify the urine .  In renal physiology , when blood is filtered by the kidney, the filtrate passes through the tubules of the nephron , allowing for exchange of salts , acid equivalents, and other solutes before it drains into the bladder as urine . The metabolic acidosis that results from RTA may be caused either by failure to reabsorb sufficient bicarbonate ions (which are alkaline ) from the filtrate in the early portion of the nephron (the proximal tubule ) or by insufficient secretion of hydrogen ions (which are acidic) into the latter portions of the nephron (the distal tubule ). Although a metabolic acidosis also occurs in those with renal insufficiency , the term RTA is reserved for individuals with poor urinary acidification in otherwise well-functioning kidneys. Several different types of RTA exist, which all
What is HYPOKALEMIA? What does HYPOKALEMIA mean? HYPOKALEMIA meaning - HYPOKALEMIA pronunciation - HYPOKALEMIA definition - HYPOKALEMIA explanation - How to pronounce HYPOKALEMIA? Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/... license. Hypokalemia, also spelled hypokalaemia, is a low level of potassium (K+) in the blood serum. Normal potassium levels are between 3.5 and 5.0 mmol/L (3.5 and 5.0 mEq/L) with levels below 3.5 mmol/L defined as hypokalemia. Mildly low levels do not typically cause symptoms. Symptoms may include feeling tired, leg cramps, weakness, and constipation. It increases the risk of an abnormal heart rhythm such as bradycardia and cardiac arrest. Causes of hypokalemia include diarrhea, medications like furosemide and steroids, dialysis, diabetes insipidus, hyperaldosteronism, hypomagnesemia, and not enough intake in the diet. It is classified as severe when levels are less than 2.5 mmol/L. Low levels can also be detected on an electrocardiogram (ECG). Hyperkalemia refers to a high level of potassium in the blood serum. The speed at which potassium should be replaced depends on whether or not there are symptoms or ECG changes. Mildly low levels can be managed with changes in the diet. Potassium supplements can be either taken by mouth or intravenously. If given by intravenous, generally less than 20 mmol are given over an hour. High concentration solutions (40 and more mmol/L) should be given in a central line if possible. Magnesium replacement may also be required. Hypokalemia is one of the most common waterelectrolyte imbalances. It affects about 20% of people admitted to hospital. The word "hypokalemia" is from hypo- means "under"; kalium meaning potassium, and -emia means "condition of the blood".
Ibuprofen-induced Hypokalemia And Distal Renal Tubular Acidosis: A Patients Perceptions Of Over-the-counter Medications And Their Adverse Effects
Volume2013(2013), Article ID875857, 4 pages Ibuprofen-Induced Hypokalemia and Distal Renal Tubular Acidosis: A Patients Perceptions of Over-the-Counter Medications and Their Adverse Effects 1The University of Sydney, NSW 2006, Australia 2Emergency Medicine Department, Nepean Hospital, P.O.

We highlight a case of distal renal tubular acidosis secondary to ibuprofen and codeine use. Of particular interest in this case are the patients perception of over-the-counter (OTC) medication use, her own OTC use prior to admission, and her knowledge of adverse reactions or side effects of these medications prior to taking them. Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) which is available over-the-counter (OTC) as a nonprescription drug. It is used widely as an antipyretic and analgesic. Our patient h

Hypokalaemia And Metabolic Acidosis
Home | Education | Hypokalaemia and Metabolic Acidosis 35 year old Aboriginal female presents with a 2/52 Hx of weakness, thirst and nausea. Presents to ED unable to lift her hands. Admitted 3/12 ago with something similar but doesnt know what it was and her medical notes are not immediately available. No other past medical history of note. Examination reveals a quiet, dehydrated lady with generalised non-lateralising weakness in all 4 limbs. Bedside venous blood gas results included: Sinus rhythm with sinus arrhythmia at a rate of 72 bpm. U waves noted most prominently in leads V1-V3 Sinus arrhythmia [sinus rhythm with slight variation (>0.16 seconds) in the sinus cycles] Normal anion gap metabolic acidosis. The 2 most common causes in ED Other causes are many and varied. There are several mnemonics out there the most recent edition of Rosen suggests: F-USED CARS Basically (and rather obviously), a metabolic acidosis is caused by either excess acid or a loss of alkali. Excess acid may be produced by the body itself or may be exogenous. Calculating the anion gap is used in the context of having made a diagnosis of a metabolic acidosis to help determine possible causes. Its an arti

Abstract PURPOSE: To focus on the interactions between insulin secretion, glucose tolerance and insulin sensitivity on the one hand and the renin-angiotensin-aldosterone system on the other. EFFECTS ON INSULIN: Insulin is a potent stimulus for hypokalaemia, sparing body potassium from urinary excretion by transporting it into cells. Potassium also appears to play a key role in the antinatriuretic effect of insulin. Insulin-induced hypokalaemia in ...
According to a 2011 national diabetes fact sheet from the Centers for Disease Control and Prevention, over 25 million people, or 8.3 percent of the United States population, have diabetes. Diabetes is the condition that results from the lack of insulin production or from insulin resistance; in diabetes, there is abnormal metabolism of glucose, which results in elevated blood glucose levels. Diabetes is associated with dysregulation of potassium, ...
Metabolic acidosis is a condition that occurs when the body produces excessive quantities of acid or when the kidneys are not removing enough acid from the body. If unchecked, metabolic acidosis leads to acidemia, i.e., blood pH is low (less than 7.35) due to increased production of hydrogen ions by the body or the inability of the body to form bicarbonate (HCO3−) in the kidney. Its causes are diverse, and its consequences can be serious, inclu ...
Bartter's Syndrome (BS) is characterized by renal tubular dysfunction with resultant severe hypokalemia. These patients exhibit poor linear growth, but clinicians have been reluctant to treat with growth hormone secondary to insulin resistance (IR) which could be worsened by growth hormone (hGH). The goal of this study was to determine insulin sensitivity in BS, utilizing the hyperinsulinemic euglycemic clamp model, and to determine the relations ...
Diabetic ketoacidosis is an emergency medical condition that can be life-threatening if not treated properly. The incidence of this condition may be increasing, and a 1 to 2 percent mortality rate has stubbornly persisted since the 1970s. Diabetic ketoacidosis occurs most often in patients with type 1 diabetes (formerly called insulin-dependent diabetes mellitus); however, its occurrence in patients with type 2 diabetes (formerly called non–ins ...
