“Nephrolithiasis from an Unexpected Cause: Phosphaturia”
A 54-year-old woman with a history of Type 2 diabetes mellitus and breast cancer with bilateral mastectomy presented to the nephrology clinic for evaluation of nephrolithiasis. She was first diagnosed with nephrolithiasis 3 years prior to arrival requiring lithotripsy and treated with oral potassium citrate. On physical examination, she was a pleasant, middle aged woman with normal blood pressure, regular pulse and mild costovertebral tenderness bilaterally. Her laboratory studies were remarkable for serum creatinine of 1.29 mg/dl (normal value 0.5-1.2 mg/dl), serum calcium 10.7 mg/dl (normal value 8.8-10.7 mg/dl), serum a...

Oral chemolysis is an effective, non-invasive therapy for urinary stones suspected of uric acid content
AbstractDespite the possible benefit from avoiding stone surgery with all its possible complications, oral chemolysis is rarely performed in patients with urinary stones suspected of uric acid content. Among the reasons for its limited use is the sparse and low-quality data on its efficacy and the lack of reliable factors predicting its outcome. We thus performed a retrospective single-center cohort study of 216 patients (median patient age 63  years) with 272 renal (48%) and/or ureteral (52%) stones treated with oral chemolysis from 01/2010 to 12/2019. Patients with low urine pH (<  6), low stone density upon non-co...

Hypomagnesemia with Hypercalciuria Leading to Nephrocalcinosis, Amelogenesis Imperfecta, and Short Stature in a Child Carrying a Homozygous Deletion in the CLDN16 Gene
AbstractFamilial hypomagnesemia with hypercalciuria and nephrocalcinosis (FHHNC) is a rare autosomal recessive disease caused by mutations in theCLDN16 orCLDN19 gene; however, few cases develop classical amelogenesis imperfecta. Herein, we report the case of a boy with early clinical renal manifestations that started at 1  year of age and presenting with dental hypoplasia and growth delay. The patient presented with vomiting, polyuria, and polydipsia. Apart from recurrent sterile leukocyturia, erroneously treated as infectious, he was normal, except for short stature and amelogenesis imperfecta with gradually discol ored ...

From Bartter's syndrome to renal tubular acidosis in a patient with Hashimoto's thyroiditis: A case report 
.
We report an HT patient who initially developed hypokalemic metabolic alkalosis and then developed metabolic acidosis within a few years. To our knowledge, this is the first report of two completely opposite acid-base disturbances associated with renal tubular diseases occurring consecutively in the same patient with HT. Our case may provide a valuable clue for exploring the mechanism of renal involvement in autoimmune diseases. PMID: 32691728 [PubMed - as supplied by publisher] (Source: Clinical Nephrology)

The Impact of Alternative Alkalinizing Agents on 24-hour Urine Parameters
To determine if alternative alkalinizing agents (AA) lead to similar changes in 24-hour urine pH and citrate compared to potassium citrate (KCIT). Many stone formers cannot tolerate KCIT due to side effects or cost. In these patients, we have prescribed potassium bicarbonate or sodium bicarbonate as alternative alkalinizing agents, though their efficacy is unclear. (Source: Urology)

Occupational kidney stones
Purpose of review Kidney stones are a common and preventable disorder. Certain occupations may increase risk for stone disease which will be discussed in this review. Few observational studies have examined this association. Recent findings Some occupations prevent individuals from drinking enough fluids to maintain a dilute urine or to void when they need to. People may have poor access to fluids or to bathroom facilities. These issues pose a risk for stone disease and are exacerbated by those who work in warmer climates. Individuals who do more activity while working, especially outdoors, perspire more, leading to m...

Efficiency of Ionic Liquids-Based Aqueous Two-phase Electrophoresis for Partition of Cytochrome c.
Abstract Cytochrome c is a small water-soluble protein that is abundantly found in the mitochondrial intermembrane space of microorganism, plants and mammalians. Ionic liquids (ILs)-based aqueous two-phase electrophoresis system (ATPES) was introduced in this study to investigate the partition efficiency of cytochrome c to facilitate subsequent development of two-phase electrophoresis for the separation of cytochrome c from microbial fermentation. The 1-Hexyl-3-methylimidazolium bromide, (C6mim)Br and potassium citrate salt were selected as the phase-forming components. Effects of phase composition; positi...

An uncommon case of arthrogryposis, renal dysfunction, and cholestasis (ARC) syndrome and review of the renal involvement: Questions
AbstractArthrogryposis, renal dysfunction, and cholestasis syndrome is a rare autosomal recessive disorder caused by mutations in the VPS33B and VIPAR genes. Most cases are fatal within the first year of life. Here we describe one of the two oldest patients with arthrogryposis, renal dysfunction, and cholestasis syndrome. This is a 12-year-old Hispanic female, from a non-consanguineous parents, diagnosed with an incomplete phenotype of arthrogryposis, renal dysfunction, and cholestasis syndrome with arthrogryposis and renal tubular dysfunction but without cholestasis. At 11 years of age, she was found to have impaired rena...

Oral dissolution therapy for renal radiolucent stones, outcome, and factors affecting response: A prospective study
Conclusion: ODT is safe and effective in the treatment of radiolucent renal stones. The efficacy was affected by stone density and stone size with more tendencies to failure with bigger stones and denser stones. Double J stent insertion may facilitate dissolution rate. There was no effect of the baseline urinarypH, hyperuricemia, or stone location on the dissolution rate of the stones. (Source: Urology Annals)
