The clinico-pathological features of nine urethral and urinary bladder polyps with prostate-type epithelium are described. The average age of the patients was 46 years. Three patients previously had cystoscopy and the lesion was not noticed on the initial examination. The commonest presentation in this series was haematuria, dysuria and frequency of(More)
A case of malignant mesothelioma of the tunica vaginalis testis diagnosed by preoperative cytology of hydrocele fluid is reported. In our view this is only the second case diagnosed by preoperative cytology. The unique feature of this case, the characteristic ultrasound appearance, was recognized and confirmation by aspiration cytology led directly to(More)
High dose intravenous stilboestrol has a direct cytotoxic effect on prostatic carcinoma cells. The purpose of this study was to assess subjective and objective responses in a select group of patients with metastatic, hormonerefractory carcinoma of the prostate with severe generalized bone pain in association with symptoms of advanced local disease.(More)
Glomerular hyperfiltration commonly associated with obesity is expected to improve postbariatric surgery. However, formula-based glomerular filtration rate (GFR) estimation in these patients is limited by body size confounders necessitating use of modified equations, the reliability of which remains uncertain. In this study, various GFR-estimating formulae(More)
Maintaining target hemoglobin (Hb) with minimal variability is a challenge in hemodialysis (HD) patients. The aim of this study is to compare the long- and short-acting erythropoietin-stimulating agents such as Aranesp and Eprex in achieving these targets. Randomized, prospective, open-labeled study of 24 weeks includes stable patients on HD >3 months, age(More)
In order to construct a generic grammatical resource for Arabic language, we have chosen to develop an Arabic grammar based on TAG formalism. Our choice is, especially, justified by complementarities that we have noticed between Arabic syntax and this grammatical formalism. This paper consists of two comparative studies. The first is between a set of(More)
A method for automatic extraction of mathematical formulas from document images without character recognition is described. This method operates into several steps. First, significant symbols of the formula are labeled. Second, this labeling is extended to adjoining symbols by using contextual. Finally, the formula is extracted from the surrounding text by(More)
Raised levels of the cardiac biomarker, Troponin I, are frequently encountered in hemodialysis patients and appear to be prognostic indicators for cardiovascular risk. Though evidence suggests that control of secondary hyperparathyroidism may reduce cardiac endpoints, the effect of the calcimimetic agent, cinacalcet, remains controversial. This(More)
