melamine is a new risk of urinary stones. gansu province is a heavily affected area and has large population and underdeveloped economy. we hypothesized that number of family members and family income may play significant roles in the formation of urinary stones. a case-control study was performed among 190 infants. results showed that the case group had less numbers of family members than the ...

Quantification of proteinuria is usually predicated upon 24-hour urine collection. Multiple factors influence urine collection and the rate of protein and creatinine excretion. Urine collection is often incomplete, and therefore creatinine and protein excretion rates are underestimated. A random urine protein-creatinine (P-C) ratio has been shown over the years to be a reliable alternative to t...

An inexpensive, rapid, and simple colorimetric test for detection of bacteriuria is described. This test does not require bacterial growth and has the marked advantage of being able to quantify bacteria, even when the organisms are present in the urine of bacteriuric patients who are being treated with antibiotics. The test is carried out with 1 ml of urine, which is processed through a 10-mm-d...

An evaluation of the standardized Romanowsky stain of Marshall et al. has been made in a routine haematology laboratory. It was noted that this stain had several advantages over the May-GrUnwald Giemsa stain used in most British laboratories. These advantages include ease and speed of preparation, a shorter staining time, and reproducibility of results. These results are described in detail. Th...

Aldosterone-producing adrenal adenoma can induce various clinical manifestations as a result of chronic exposure to aldosterone. We report a rare case of a 37-year-old man who complained of general weakness and polyuria. He was diagnosed with aldosterone-producing adrenal adenoma and nephrogenic diabetes insipidus. Aldosterone enhances the secretion of potassium in the collecting duct, which ca...

Figure 1. Atypical and multinucleated plasma cell infiltration in the bone marrow aspirate (Wright's stain, 100x). A 66-year-old male patient was admitted to the hospital with backache, fatigue, and paraesthesia and spasm in both legs. He had lower extremity numbness and bladder and bowel incontinence. Physical examination revealed the absence of bilateral lower extremity reflexes and lower ext...

Environmental concerns related to perfluoroctanoic acid (PFOA) led to a re-examination of the methods for imparting stain resistance and stain repellency to textiles. Non-PFOA fluoropolymer finishes have been formed on cotton knits by admicellar polymerization, a surface analogue of emulsion polymerization. Fabric samples were characterized by a drop test, contact angle measurements, SEM, eleme...
