Maltese cross-like crystals in the urinary sediment of a diabetic patient
نویسندگان
چکیده
The urinalysis is an important step in the diagnostic workup of patients with kidney diseases. The assessment of the urine includes evaluation of its physical characteristics (colour, clarity and volume), the measurement of biochemical parameters using dipstick tests (urine pH, blood, glucose, ketones, bilirubin, urobilinogen and protein) and importantly the evaluation of the sediment by phase contrast microscopy that has filters to polarize light for the identification of lipids and crystals. The results of the urine analysis are greatly influenced by the pre-analysis sample handling. In particular, improper urine collection methods interfere with test accuracy that may prompt clinicians to further unneeded tests or lead to false diagnosis [1].

A urine finding associated with obesity.
Corn starch can be identified by its physico-chemical property of producing Maltese cross birefringence under polarized light. In the urine there are few other compounds that may cause a similar Maltese cross picture: cholesterol esters in nephrotic syndrome and 2,8 dihydroxyadenine (2,8DHA) crystals in rare patients with congenital adenine phosphoribosyltransferase deficiency. Both talc and st...
متن کاملPhenol Based RNA Isolation is the Optimum Method for Study of Gene Expression in Human Urinary Sediment
Evaluation of gene expression in urinary sediment has been considered as a promising non-invasive approach for biomarker identification of kidney diseases. Nonetheless, there are several challenges in extraction of RNA from this valuable source of biomarkers, mostly because of the factors that have influence on quality of isolated RNA such as low cellular content. Accordingly, we compared the q...
متن کاملTherapeutic Effects of Parenteral Vitamin C (Ascorbic Acid) on Struvite Crystalluria in Domestic Male Cats
BACKGROUND: Struvite crystals (Magnesium Ammonium Phosphate) are one of the most common causes of urolith formation in cats. Presence of these crystals in urea leads to urinary obstruction and idiopathic cystitis. The prevalence of urinary crystals has increased in recent years, thus there has been a growing interest in development of noninvasive, fast responsive therapies. Vitamin C is a safe...
