BACKGROUND/OBJECTIVES The criteria for the diagnosis of non-gonococcal urethritis (NGU) on a Gram stained urethral smear are derived from previous studies which used culture as a diagnostic test for Chlamydia trachomatis. Our objectives were (1). to re-assess the relation between urethral polymorph count and C trachomatis infection, using ligase chain(More)
OBJECTIVES To determine the reliability of the diagnosis of non-gonococcal urethritis (NGU), and the variation between and within microscopists, from urethral smears at a large London genitourinary medicine clinic. METHODS A senior microscopist (SM) preselected 60 Gram stained urethral smear slides, 20 negative (<5 polymorphs/hpf), 20 low grade NGU (5-20(More)
Rectal gonorrhoea (GC) in men may cause anal discharge or proctitis, but these symptoms have been shown to correlate poorly with rectal infection. Culture of Neisseria gonorrhoeae from an exposed site offers a readily available, sensitive and cheap diagnostic test, and is currently the gold standard for diagnosis; however, these results can take a few days(More)
Details of the in vitro fertilization and embryo transfer programme at the Department of Obstetrics and Gynaecology of the H. F. Verwoerd Hospital and the University of Pretoria are presented. From 1 March 1982 to 30 November 1983, 67 cycles in 47 patients were induced using clomiphene citrate and human chorionic gonadotrophin (hCG) (46 patients) and human(More)
A retrospective study was performed in a department of genitourinary medicine to determine the prevalence and clinical features of urethral and cervical infection with Neisseria meningitidis among patients being screened for sexually transmitted diseases. During the 28 month period of the study 11 isolates (from 10 patients) of N. meningitidis were(More)
Rice bran, which is one of the major by products of paddy contain high quality proteins and edible oil apart from fibre, ash and NFE (nitrogen free extract). The existing solvent extraction method employs n-hexane as the most viable solvent for the extraction of oil from rice bran. But the high cost and scarce availability of n-hexane resulted in(More)
Sensor arrays are useful for many purposes. Our interests include quasi-distributed intrinsic fiber optic arrays, those distributed along the length of an optical fiber. We have demonstrated an optical time-of-flight approach to distinguishing the fluorescence output of such arrays, as well as a synthesis of combinatorial libraries that takes advantage of a(More)
INTRODUCTION: Current clinical cardiac MRI uses a series of 2D cine-SSFP and may suffer from slice misregistration due to inconsistent breath-holding positions. Some severely ill or pediatric patients may be unable to perform satisfactory breath-holds. In this study, a 3D free-breathing self-calibrated radial GRAPPA cine-SSFP pulse sequence was developed to(More)
An iterative convex projection method is presented to remove motion artifacts in time-resolved MRA images. Placing constraints on the temporal changes allowed to occur from one image to the next identifies motion corrupted k-space coefficients which can then be replaced by values obtained by iteration. Specifically High-pass phase filtering is combined with(More)
