Background   Ethnicity play a role in the occurrence of urinary stones, probably related to climatic, environmental and dietary factors in ethnic groups. The association between ethnicity, age, clinical profile, stone size with type of ureteric stones among males with urolithiasis was studied.   Materials and Methods Male patients (>18 years) with lower ureteral stones size <10mm attending outpatient department of Urology, at a private hospital, Ajman over a period of one year were included. Ethics approval was obtained from Institutional Ethics Committee. Data was retrieved from the case records which included socio-demographic variables (age, ethnicity), clinical profile (ureteric colic, duration of pain, other complaints), and laboratory investigations (type of stone, stone size). Descriptive and inferential statistics were performed with SPSS-20 and p values <0.05 considered significant. Results 185 male patients were included. Mean age was 41.5 (7.3) years, range (22-71) years. Out of the total, 81 (43.8%) patients were Asians, 81(43.8%) Arabs and 23 (12.4%) were of other ethnicity. Most patients (95.1%) presented with ureteric pain. 49 (26.5%) had family history of stone disease where calcium oxalate monohydrate and uric acid stones were common, with majority being first degree relation. Data on stone type was available for 90 patients; of which, 21 were calcium oxalate monohydrate, 33-calcium oxalate dehydrate, 24-uric acid and remaining 12 other form of stones. Average age for different types of stone was 38.3, 41.6, 39.4 and 42.8 years for calcium oxalate monohydrate, calcium oxalate dehydrate, uric acid and other types respectively. Conclusion Uric acid stones were more prevalent among Asians and calcium oxalate-dehydrate stones among Arabs. Future studies can be conducted among multiethnic population focusing on dietary pattern and stone analysis.DOI: http://dx.doi.org/10.3126/nje.v4i4.11359 Nepal Journal of Epidemiology 2014; 4(4):393-98

The urolithiasis is one of the most motives of dogs and cats complaints attended with urinary affections. Objective of the work was to show the importance of the diet with a factor of prevention and treatment of urolithiasis in dogs and cats. The research technique used was bibliographic research. The formation of kidney crystals and stones with causes as decreased urination associated with urine supersaturation, being able to be related to dietary factors. Amoung the main existings uroliths, stand out those made of struvite and calcium oxalate. The nutrition can be related to the formation, prevention and treatment of urolithiasis, mainly in relation to the pH control and acid/basic balance present in industrialized rations. Given the above, the research presents information that shows the interference of nutrition in dogs and cats with urolithiasis. Keywords: Urolithiasis. Struvite. Calcium oxalate. Diet.

Background and objectives: The odds of nephrolithiasis increase with more metabolic syndrome (met-s) traits. We evaluated associations of metabolic and dietary factors from urine studies and stone composition with met-s traits in a large cohort of stone-forming patients. Design, setting, participants & measurements: Patients >18 years, who were evaluated for stones with 24 h urine collections, July 2009-December 2018, had records reviewed retrospectively. Patient factors, laboratory values and diagnoses were identified within 6 months of urine collection and stone composition within 1 year. Four groups with 0, 1, 2, > 3 met-s traits (hypertension, obesity, dyslipidemia, diabetes) were evaluated. Trends across groups were tested using linear contrasts in analysis of variance and analysis of covariance. Results: 1473 patients met inclusion criteria (835 with stone composition). Met-s groups were 0=684, 1=425, 2=211, 3 and 4 =153. There were no differences among groups for urine volume, calcium or ammonium (NH4) excretion. There was a significant trend (p<0.001) for more met-s traits being associated with decreasing urine pH, increasing age, calculated dietary protein, urine uric acid, oxalate, citrate, titratable acid (TAP), net acid excretion (eNAE) and uric acid supersaturation. The ratio of ammonium to net acid excretion did not differ among the groups. After adjustment for protein intake, the fall in urine pH remained strong, while the upward trend in TAP excretion was attenuated and NH4 decreased. Calcium oxalate stones were most common, but there was a trend for more uric acid (p<0.001) and fewer calcium phosphate (p=0.09) and calcium oxalate stones (p=0.01) with more met-s traits. Conclusions: Stone forming patients with met-s have a defined pattern of metabolic and dietary risk factors that contribute to an increased risk of stone formation including higher acid excretion, largely the result of higher protein intake, and lower urine pH.

Calcium is an important element in the growth and development of plants and one form of calcium is calcium oxalate. Calcium oxalate has been found in leaf seed, stem material plant tissue culture, fungi and lichen using one or more of the following methods—polarized light microscopy (PLM), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and x-ray diffraction.Two methods are presented here for qualitatively estimating calcium oxalate in dried or fixed tobacco (Nicotiana) leaf from different stalk positions using PLM. SEM, coupled with energy dispersive x-ray spectrometry (EDS), and powder x-ray diffraction were used to verify that the crystals observed in the dried leaf with PLM were calcium oxalate.

Many papers have been published on the structure of calcium oxalate crystals in plants, however, few deal with the early development of crystals. Large numbers of idioblastic calcium oxalate crystal cells are found in the leaves of Vitis mustangensis, V. labrusca and V. vulpina. A crystal idioblast, or raphide cell, will produce 150-300 needle-like calcium oxalate crystals within a central vacuole. Each raphide crystal is autonomous, having been produced in a separate membrane-defined crystal chamber; the idioblast''s crystal complement is collectively embedded in a water soluble glycoprotein matrix which fills the vacuole. The crystals are twins, each having a pointed and a bidentate end (Fig 1); when mature they are about 0.5-1.2 μn in diameter and 30-70 μm in length. Crystal bundles, i.e., crystals and their matrix, can be isolated from leaves using 100% ETOH. If the bundles are treated with H2O the matrix surrounding the crystals rapidly disperses.
