Directed Reading

Diet and nutrition are an important part of living well with kidney disease. "Renal tubular acidosis: developments in our understanding of the molecular basis". A If new, are the stones calcium phosphate? When the latter is defective, urine itself is invariably Such an alkaline urine is common among idiopathic calcium phosphate stone formers who certainly do not have dRTA. This leads to the clinical features of dRTA:• Since selective tubule disorders seem unlikely the low serum potassium did not recur possibly you have abnormal aldosterone handling. If I could just follow up a bit based on what you said — My serum CO2 are not fasting measurements, I am not sure if that changes the picture. The other thing is I have been having lower urinary tract symptoms mainly very frequent urination with small volume each time , which a urologist diagnosed as chronic pelvic pain and i had received some physical therapy. It has been an interesting experience for me and I learned to appreciated a lot of the things you talked about here. "Nephrolithiasis in renal tubular acidosis". Ask students, "Given this title, what do you think the passage will be about? Oftimes, the dRTA can improve, but may not. There are a few other conditions I currently have which I am not sure if they could also be relevant. " Make changes to the predictions on the transparency or chalkboard. Blood is held at a pH just above that of water by a buffer system consisting of bicarbonate and carbon dioxide CO 2 gas. formation related to alkaline urine, , and low urinary citrate. But urine is normally pH 6, more than 10 times more acid than blood. My secretary can arrange a visit and also collect all of your information so we will have it available. The Calcium to Citrate Proportion Other articles explore the remarkable properties of urine citrate. I still have high normal calcium levels. Most of the points center between 23 and 30 for total CO 2. As your kidney disease progresses, your dietary needs might also change. Increase the professional body of knowledge and its dissemination. Of these, HCO 3 — massively predominated. Inside the tissue are masses of crystal deposits filling much of the space. Ask students to cite the text which caused them to confirm or change a prediction. You do not mention low urine citrate, which is a remarkable feature of dRTA. Patients with dRTA can be asymptomatic or can present with polyuria, polydipsia, weakness and fatigue symptoms associated with hypokalemia. To consider and advise on courses of study and technical training and to disseminate information designed to promote and ensure the fitness of potential DRTA members. Please note: Studies listed on the ClinicalTrials. They are also larger than apatite deposits, about 0. As the students move through the text, their predictions are changed and modified according to the new information that is provided from the text. The following steps outline the DR-TA process. I had a 24 hour urinalysis done about 1. Blood tests will be used to measure the acid levels in the blood, electrolytes, such as sodium, potassium and chloride. When it goes up, acid has been removed — or new alkali added. Get fasting morning bloods for potassium at reasonable intervals — weekly then if not low monthly or so — for a while and see. The cases, my few and those in the papers I selected, mostly came for care because of stones. In another article — this one is already too long and tiring — I will review more of the scanty long term outcome data for this disease. One might at this point like some hard statistics about the actual values of serum CO 2 even though the large pH graph has made a visual impression. Therefore the mean of our cases — 3. For this analysis, I will use only dRTA cases in my clinical series because their lab values were obtained exactly as were values for the other stone forming groups I need as a contrast. A DRTA may be used for an individual separately, for a small group or even the class as a whole. In her long career, Joan did this many times. How to use directed reading thinking activity Teachers should follow the steps below when creating a DRTA. It encourages students to be active and thoughtful readers. Breathing difficulties• How can you do a Directed Reading Thinking Activity in your classroom? At the end of each section, students go back through the text and think about their predictions. Levels between these to vary from urinalysis to urinalysis. The main treatment for primary dRTA involves alkali agents, which are used to reduce excess acid in the blood. Students read up to the first pre-selected stopping point. In a subsequent article I hope to expand on diagnosis and treatment, the bone and mineral disorders, genetic transporter disorders, and take up the novel modern issue of acid retention and its effects on kidneys. When searching for an appropriate text, consider the following:• Normals and Common Stone Formers The blue circles and tiny dots show us the variable urine pH of normal people and common stone formers. " Accept and record all predictions on the transparency or chalkboard. Teachers direct and activate students' thinking prior to reading a passage by scanning the title, chapter headings, illustrations, and other materials. Modify Predictions Start reading the text. — A resource on meeting the challenges of living with dRTA. The large clusters marked by asterisks were in an obstructed upper pole calyx and certainly masses of crystal, but whether in tissue or the collecting system we would not be able to find out. Introduce the text, the purpose of the DRTA, and provide examples of how to make predictions. I was diagnosed with incomplete dRTA about 6 years ago after parathyroidectomy. Distal renal tubular acidosis can be inherited primary dRTA or be caused by another disorder or medication secondary acquired dRTA. Statistics Adjusted Mean Citrate Excretions One cannot leave this without some quantification of differences. A patient is given an acid load test using ammonium chloride. dRTA By contrast, dRTA is a more diffuse disease, affecting more or less all of the tubules. Prior potassium values have been at the low end of normal 3. He also mentioned I might be having an undiagnosed stone. This process should be continued until students have read each section of the passage. Arrows point to some obvious clusters. I took this conclusion for granted based on what I read on this uptodate page. "Urinary acidification assessed by simultaneous furosemide and fludrocortisone treatment: an alternative to ammonium chloride". Uric acid stones cannot be due to dRTA as they require an acid urine, so I suspect she is entirely different altogether. The best way to visualize this relationship is simply to graph one against the other in comparable units. "What was wrong with Tiny Tim? Coe, I want to briefly update you about my condition. 04, respectively , and below normal phosphate excretion 0. It involves correction of the acidemia with oral , or. Low potassium levels• I have found most of my acquired dRTA among those with. Once again, when possible, I have plotted their lowest urine pH values — from acid loading — against their CO 2 values before the acid load. Their serum CO 2 values are almost all to the right — higher than — those for the red symbols dRTA on average. The best fit regression line — red line — runs below identity. The difference between the sulfate and alkali anions measures the acid load from a given food, and the average of foods the acid load from a diet. Does the text provide ample predictive points where reading can be interrupted and discussion can be started? The vegan diet will cause a high urine pH, but not a low serum potassium or CO2. Develop and foster cooperative national and international networks. 000 Serum CO 2 is obviously low in dRTA, the very hallmark of the disease. Do Patients with dRTA Make Stones? Blood is nearly the same, pH 7. And, they have a higher urine pH. Incomplete dRTA My Own Prejudices Here is a bafflement for me. I wish I lived closer, I live in Nebraska. Repeat instruction 2 and 3 until you reach the end of the text. Provide information regarding the implementation and outcomes of DRTA plans and projects. In the recessive forms of dRTA, progressive and irreversible deafness often occurs. We use potassium, not sodium alkali to restore systemic potassium deficits and avoid raising urine calcium by sodium loading. 0001 in all cases except CaOx vs. When you use this strategy, guide and stimulate students' thinking through the use of questions. The high significance for dRTA is remarkable given I use only my small group of cases. I eat mostly Paleo for my Ankylosing Spondylitis. Higher acid can increase the risk of kidney stones, so you may be asked to avoid consuming foods that can increase acid production in the body. When used with a group, it helps develop communication skills in the students, not just reading skills. However, once they gain experience with this strategy, have them read the sections silently. The low potassium and CO2 are suspicious as is the high urine pH. Why use directed reading thinking activity? If you have high acid levels acidosis , you may also be asked to reduce or avoid foods that can increase acid levels. Family history of dRTA is common in patients with dRTA and a common clue to diagnosis. I did use proton pump inhibitor in December and March as part of the therapy to remove Helicobactor pylori in the hope that this would improve my platelets at the time. Lacking a systemic disease or drug, which usually means the trait is genetic, or in the event that treatment of systemic disease leaves residual systemic acidosis, one treats with potassium alkali in a dose sufficient to restore serum CO 2 to within the normal range. Currently managing the disease with Kcitrate, fluids and diet. Distal renal tubular acidosis Other names Type 1 of a sufferer, a complication of both distal and proximal RTA. The other stone diseases cluster to the far left: small bowel resection, obesity bypass, cystinuria, uric acid stones. Moreover, to poison new formed crystals and abridge their growth, citrate must be free — not bound to calcium. Ask students to revise their predictions based on this new information. But the one I care about — and you need to care about — is sulfate. I am now in jeopardy of making other kidney stones because of diet. What is the process that I need to follow? If I had a local name for you I would be pleased, but alas. 8 mm, so the total volume of tissue occupied is much greater. Regards, Fred Coe• As , these calcifications can be stones or masses of tissue calcium deposits. But this offers no specific therapy beyond what we always offer and therefore one cannot justify such testing as patient care but only as research. A recessive subtype of dRTA associated with anemia has also been described in Southeast Asia. Later the urinalysis shows my urine pH is 7. The black regression line is not different from uric acid. In those who do have such a defect, stones and crystals are usually far more massive and damaging to kidneys. If it is high, one might imagine a false diagnosis of dRTA. That is the very make and mark of distal renal tubular acidosis dRTA. Not all people living with dRTA will experience the same health problems. Lesson Plan from the Video Text Used: Baba Yaga as retold by Open the following to see how the text was chunked: Open the following to see the list of pre-prepared comprehension questions:. Clinical Practice After all this, this labyrinthine odyssey, this thicket of numbers and graphs, what are patients to understand, and what am I telling physicians who are not themselves as particularly interested in dRTA as I am? So esoteric a point yet one we must encounter and wrestle with. The teacher then prompts the students with questions about specific information and asks them to evaluate their predictions and refine them if necessary. You would be right both times. References [ ]• For example, water has a pH of 7, meaning the concentration of protons is 10 -7 0. Prepare a list of comprehension questions that can be asked throughout the activity. 0001 for all comparisons but dRTA vs. But saying this is to miss the main point. She has had 12 broken bones, and bilateral osteochondritis dissecans, could these bone issues be related to her dRTA? When the former is defective proximal RTA , filtered bicarbonate cannot be fully reabsorbed as in normals, so more is delivered downstream to the collecting ducts. Treating the underlying disease causing dRTA• demineralisation causing in children and in adults The symptoms and sequelae of dRTA are variable and range from being completely , to pain and from , to and severe in childhood forms as well as possible and even death. Research on new treatments are also addressed. I am not sure if it is appropriate to ask for you medical opinion here. The teacher asks questions such as:• Excellent scientists have found such cases, and I show points them on my graph as red symbols — meaning failure to lower urine pH fully — with normal serum values. , but not exactly as I propose to do here. dRTA and Acid Loaded Normals The red circles are clinical measurements from my patients with known dRTA. Another is to administer a sodium retaining steroid and a dose of furosemide and determine the lowest pH attained. The dose depends on the severity of hypokalemia. What are the symptoms of distal renal tubular acidosis? Ask students to support their claims. Genetic testing is possible and this disease can present in strange ways as in your case report. Also includes suggestions for letters to school explaining dRTA. So most of the red up triangles have the unique signature of dRTA: high urine pH and low serum CO 2. The teacher asks questions about the text, the students answer them, and then develop predictions about the text. Distal renal tubular acidosis dRTA is a disorder of impaired net acid secretion by the distal tubule characterized by hyperchloremic metabolic acidosis. The major goal of therapy is to restore normal growth and prevent kidney stones. But their kidneys respond to an acid load challenge less well than normal thus disclosing some defect in lowering urine pH. This will free up even a higher fraction of phosphate to mate with calcium, thereby raising supersaturation for any urine calcium, volume and citrate. Both can lower serum magnesium, which you have not mentioned. - This resource explains the current available treatments for dRTA. And in general, the result is stones, with little or no tubule plugging. But unlike the not uncommon idiopathic calcium phosphate stone formers, those with dRTA have unrelentingly high urine pH and acid retention. Many calcified objects more or less fill it. However, a few months later I came across an oppotunity to meet with another nephrologist, he suggested that I may not have a kidney issue based on my lab result. Even so, elaborate as it is, this article tells only part of the story. It is true that the CaP stone formers make a more alkaline urine than do the CaOx stone formers, and t. Urine pH Certainly the high urine pH is part of the story. Because most of the potassium in the body is inside cells, low serum values almost always mean low potassium levels inside cells. See also [ ]• This happens because as they conserve water kidneys concentrate urine calcium phosphate salts far above their levels in blood. Do you still feel it might warrant further attention with only bicarbonate being off, and not excessively low? Urine calcium excretion is unrelated to minimum urine pH. Tubule cells acidify the filtrate in the proximal tubule, and then again later on, in the collecting ducts. But telemedicine is here, now, and I can provide care, I believe, even for someone in another state. In other words, inability to lower urine pH maximally may point to carrier states for hereditary dRTA. Click on the link to go to ClinicalTrials. So it is the balance between serum chloride and CO 2 that really swings in dRTA compared to — I guess I can make this sweeping a statement here — all other groups. But a brief search on PubMed will yield many others as well. This points out in practical terms how the very essence of dRTA is a loss of tubule acidification out of proportion to loss of glomerular filtration. To establish or certify continuing professional development programs for Diversional Therapists. Fatigue• Students may get impatient if they are only able to read a sentence at a time, or they may get bored or tired if they are required to read paragraphs at a time. It is interesting to learn about the different strategies to use while teaching one how to read. The brings together data about this condition from humans and other species to help physicians and biomedical researchers. I am a 29 year old male and recently visited my primary care following muscle shaking and weakness. A few cases lacked pre-acid load serum CO2 so I plotted the values after acid loading. What are the benefits to DRTA? Remarkably, their points overlap exactly with those from the common stone formers. Note: When doing this activity for the first time, read the text aloud to the students. The diet acid load is mainly — for the most part — sulfuric acid derived from the oxidation of sulfur on the two amino acids cysteine and methionine. About 3 deposits per mm 2 but over 1. Alkali therapy is the standard treatment to achieve normal serum bicarbonate levels. Correcting acidosis with medications like sodium bicarbonate and sodium citrate also called alkali therapy• It teaches students to monitor their understanding of the text as they're reading. Wrong OM, Feest TG, MacIver AG 1993. Otherwise they would obliterate the other symbols. A Way To Picture It What all this means is that as serum CO 2 falls in dRTA, serum chloride should more or less rise in proportion. Anyways, your message is very reassuring. The larger red triangles are from my practice, the smaller ones are published data. If it were biased toward alkali load, dRTA would not appear as it does. The high SS CaOx and CaOx stone content with modest urine calcium makes me wonder if urine oxalate is high or volume low. The conclusion was basically that this was a tubular injury with unknown etiology and I might have to take Amiloride for the rest of my life. Do you have any recommendations of a nephrologist in Nebraska? Genetic Causes In a search for , this somewhat older paper deserves attention. DR-TA is a strategy that explicitly teaches students to good reading habits. 3 merely one signpost along the way. - Includes questions for your healthcare professional and how to work with your healthcare team. One might think it a small thing to compile its thousands of rows of data, given we have computers. There is much to be learned about stone formers with high urinary pH. Some had bone disease, some children did not grow properly. But in general calcium phosphate predominates. This buildup of acids in the blood is known as metabolic acidosis. "Risk factors for ifosfamide nephrotoxicity in children". She has been treated with Bicitra since then. Secondary dRTA can happen at any age, but usually happens later in life. But RTA is a powerful exaggeration of high pH. The DRTA process encourages students to be active and thoughtful readers, enhancing their comprehension. appeals to me for its restraint and focus. This is because kidneys have lost their , and cannot clear sulfate from blood normally. In our regression, the F value for urine calcium as a covariate was 17, that for stone former type was 6. This list should include all prescription medications, over-the-counter medications and herbal supplements you are taking. 0001 all three comparisons with full adjustment for multiple comparisons. And as I mentioned before, my nephrologist was looking for autoimmune disease that may cause the presumed tubular injury. So evaluation must be very sensitive to all medication use. The last time I did an US was May last year mainly to check the spleen but the results also suggests both kidneys looks fine and there were no shadowing calculi. — Includes ways for parents to cope with the day-to-day aspects of dRTA, and how they can speak with their children about this disease. But the lower pH would make that crystal CaOx, not CaP. Toxins, including more commonly causing pRTA than dRTA , and. The result is too alkaline a urine. The red up triangles show dRTA cases given an acid load to force urine pH as low as it can get. He calculated the fraction of excretion for me. Arterial blood gas• When compared quantitatively in terms of numbers of deposits and deposit size dRTA vastly outweighs other stone diseases. But despite that limitation, their exteme citrate deficit and extreme pH elevation permits formation of masses of crystals to fill most collecting ducts and create numerous calcium phosphate stones. I am wondering if you have any thoughts on my case. Bruce LJ, Wrong O, Toye AM, et al. Classroom Connections: Strategies for Integrated Learning. Take another look at the micro-CT. Serum and therefore filtrate bicarbonate falls, better matching what remains of proximal reabsorption so the distal delivery slows to a trickle. Perhaps not all their ability, but some significant part of it? The disease is characterized by hyperchloremic metabolic acidosis. Writing may be included as part of the DRTA. Is there anything else I can do?。 。 。 。 。 。
