ABSTRACT
A series of 114 urinary stones collected from 4 community hospitals were analyzed for chemical composition by infrared spectroscopy. These stones were surgically removed from 95 adults (male/female = 2) and 25 children (boy/girl = 3) during the period of 1988. Calcium oxalate was the most frequent component found in adult stones of both upper (96%) and lower (80%) urinary tracts (UUT and Lut). Of the childhood stones, while calcium oxalate was seen in all 5 UUT stones (100%), uric acid/urate was the most common component of stones from LUT (64%). The calculi were classified according to their main components into 4 type; calcium oxalate, calcium phosphate, magnesium ammonium phosphate and uric acid/urate. The most predominant stone type found in adult UUT and LUT and in childhood UUT was calcium oxalate whereas uric acid/urate was the main type of childhood LUT stones. Although our data was obtained using a qualitative approach, in general, our observations agree with those semi-quantitative wet chemical methods reported by others in this region.
ABSTRACT
This study was aimed to observe the effects of an oxalate-rich vegetable, Cha Plu (Paper sarmentosum), on risk of urinary stone formation. Sixty rats were used as experimental animal models and were divided into 3 equal groups. While group 1 was fed with normal food without the vegetable, group 2 and group 3 were fed with food containing 1% and 5% dry vegetable leaves, respectively. Twenty-four-hour urine specimens were collected and analyzed for calcium, oxalate, phosphate and creatinine. The analysis was carried out once every fortnight for 26 consecutive weeks. The rats were killed and urinary tract examination for the existence of stone was performed on the 26th week. The results showed that the patterns of growth, food and water intake, collected urine volume as well as urine composition among the 3 groups of rat were similar. In urinary tract exploration, a one-millimeter-size stone was found in renal pelvis of one rat in group 3 Chemical analysis, however, reealed that the stone was not the calcium stone type (calcium oxalate and/or calcium phosphate as the main components). If absorption processess are similar between the rats and the men, our results are not consistent with the propose that ingestion of oxalate-rich vegetable posts a high risk to urinary stone formation.
ABSTRACT
Background: I-sarn syndrome (ISS) consists of multiple chronic complaints including: myofascial pain, back pain or lower abdominal pain, dyspepsia, poly-arthralgia, headaches, fatigue, history of dysuria, and/or any of these made worse by consuming bamboo shoot.Objectives: To determine the prevalence of ISS and their associated factors in rural community, Khon Kaen Province.Methods: A cross-sectional analytic study in 16 rural villages from 4 districts. Subjects, between 15 and 60 years of age, were randomly selected by multistage sampling.Results: 1,128 individuals were participated, 38% were male, 45% were older than 45 years and most of them were farmers (71.1%). Age-sex adjusted prevalence of ISS was 29.4%. Prevalence of myofascial pain, back pain/lower abdominal pain, dyspepsia, poly-arthralgia, headaches, fatigue, and dysuria was 33.7, 37.7, 29.9, 11.4, 39.8, 30.9 and 18.5%, respectively. The prevalence of people whose symptoms aggravated by bamboo shoot was 33.5%. ISS patient was significantly older, more debt, higher creatinine level, more frequent visited at health center and community hospital (p
