A liquid chromatographic tandem mass spectrometric method for the identification and quantification of 18 cardiovascular drugs was developed in order to evaluate two cases of fatal intoxication involving diltiazem and amlodipine respectively. Samples were simply diluted and centrifuged using a three-steps procedure with methanol, acetonitrile and mobile phase. The method proved to be selective and all the validation parameters fulfilled the acceptance criteria. In particular, linearity was studied in the range limits of quantitation (LOQ)-1,000 ng/mL (LOQ ranging from 0...

The lifespan of cats with non-obstructive kidney stones is shortened compared with healthy cats indicating a need to reduce stone formation and minimize chronic kidney disease. The purpose of this study was to investigate the effects of increasing dietary polyunsaturated fatty acids (PUFA) on urine characteristics. Domestic-short-hair cats (n = 12; mean age 5.6 years) were randomized into two groups and fed one of two dry-cat foods in a cross-over study design. For one week before study initiation, all cats consumed control food that contained 0...

BACKGROUND: Idiopathic hypercalciuria is a group of diseases which can be manifested with urinary symptoms. Its importance is due to high prevalence, recurrent infections, and stone formations which are often asymptomatic. OBJECTIVE: The objective of this study was to determine the prevalence of idiopathic hypercalciuria in children with urinary system related symptoms in Bandar Abbas in 2014. METHODS: This descriptive cross-sectional study was done in 2014 in a children's hospital in Bandar Abbas (southern Iran) on 321 children who were between 2 months to 14 years old...

A 60-year-old African-American man with a medical history significant for heavy alcohol abuse, hypertension, delirium tremens, nephrolithiasis and seizure disorder was brought to the hospital with altered mental status. He was found to have high anion gap metabolic acidosis with significantly elevated lactate along with an elevated osmolal gap and calcium oxalate crystals in his urine. With this combination of findings, ethylene glycol poisoning was high in the differential. This case report describes why ethylene glycol poisoning was not the diagnosis in this patient despite the presence of these three classic laboratory findings, therefore emphasising the fact that these findings should not be taken at face value because they can be seen collectively in a patient yet each have a different cause...

INTRODUCTION: It is well documented that patients with osteoporosis (OP) have high incidence of hypercalciuria (HC). However, the mechanism of HC in patients with OP is not well established. It is thought to be the result of high bone turnover (HBT) with excessive bone resorption. OP also frequently presents with low bone turnover (LBT). At this time, it is not clear whether OP with LBT is also associated with hypercalciuria. PURPOSE: The purpose of this study is to evaluate urinary calcium excretion in osteoporotic patients with HBT and LBT...

Primary hyperparathyroidism is a disease that occurs more frequently than generally thought and is often overlooked. Classical symptoms are bone pain and osteoporosis, renal calculi and peptic ulcers. Many patients are asymptomatic or have unspecific complaints. It is easy to establish the biochemical diagnosis based on calcium and parathormone (PTH) levels and 24-h urine calcium excretion. The most sensitive localization procedures for parathyroid adenomas are sonography and Tc-99(m)-MIBI scintigraphy. The indication for surgery is undisputed in symptomatic patients; however, there is controversy concerning patients without classical symptoms...

REVIEW
Farahnak Assadi, Mastaneh Moghtaderi
Nephrolithiasis is a common health problem across the globe with a prevalence of 15%-20%. Idiopathic hypercalciuria is the most common cause of nephrolithiasis, and calcium oxalate stones are the most common type of stones in idiopathic hypercalciuric patients. Calcium phosphate stones are frequently associated with other diseases such as renal tubular acidosis type 1, urinary tract infections, and hyperparathyroidism. Compared with flat abdominal film and renal sonography, a noncontrast helical computed tomography scan of the abdomen is the diagnostic procedure of choice for detection of small and radiolucent kidney stones with sensitivity and specificity of nearly 100%...

For mammals, oxalate enters the body through the diet or is endogenously produced by the liver; it is removed by microbial oxalate metabolism in the gut and/or excretion in feces or urine. Deficiencies in any one of the these pathways can lead to complications, such as calcium oxalate urinary stones. While considerable research has been conducted on individual oxalate-degrading bacterial isolates, interactions between oxalate and the gut microbiota as a whole are unknown. We examined the reduction in oxalate excretion in a rat model following oral administration of fecal microbes from a mammalian herbivore adapted to a high oxalate diet or to fecal transplants consisting of two different formulations of mixed oxalate-degrading isolates...

Environmental low-dose melamine exposure has been associated with urolithiasis risk in adults, but it is unclear if this exposure can cause early renal damage. This cross-sectional study investigated the association of this exposure and early renal damage in patients with calcium urolithiasis. We recruited patients diagnosed with upper urinary tract calcium urolithiasis from three hospitals in southwestern Taiwan between November 2010 and January 2015. All patients completed a structured questionnaire and provided one-spot urine samples for the measurement of melamine level and markers of early renal injury, including N-acetyl b-d-glucosaminidase (NAG), β2-microglobulin (β2-MG), and microalbumin...

The aim of this study was to investigate how controlled UVB irradiation in combination with reduced nutritional vitamin D (vitD) supply affects vitD status and Ca metabolism of growing goats and sheep. The hypothesis was that, like dairy cows, goats and sheep are able to compensate for the missing nutritional supply of vitD through endogenous production in the skin, with the consequence of a high vitD status and a balanced Ca homeostasis. Sixteen lambs and 14 goat kids aged 3 and a half months were housed in an UVB free environment and fed hay and a vitD-free concentrate over a period of 13 wk...

BACKGROUND: Generally, a higher calcium diet is fed to fracture patients after surgery. However, recent studies have indicated that higher dietary calcium intakes increase the risk of urinary stones for fracture patients. Therefore, this study aimed to observe the variation in urinary calcium levels among fracture patients who underwent surgery, based on fracture type, fracture location, age and gender. METHODS: A total of 768 subjects were enrolled in this study from 2012 to 2015 and were divided into 2 groups: group A (fracture patients who underwent surgery) and group B (normal patients without fracture)...

It has been proposed that a reduction in intracellular calcium causes an increase in intracellular cAMP and PKA activity through stimulation of calcium inhibitable adenylyl cyclase 6 and inhibition of phosphodiesterase 1 (PDE1), the main enzymes generating and degrading cAMP in the distal nephron and collecting duct, thus contributing to the development and progression of autosomal dominant polycystic kidney disease (ADPKD). In zebrafish pde1a depletion aggravates and overexpression ameliorates the cystic phenotype...
