OBJECTIVE To determine the aetiology of genital ulcers and discharges in rural south western Uganda and to assess response to syndromic treatment. METHOD A longitudinal, prospective study using laboratory testing and questionnaires to evaluate 561 adult men and women presenting with clinically verified genital ulcers, urethral, or vaginal discharge at a general outpatient clinic and two healt...

BACKGROUND No sequential long-term data exist for Greece on the etiological evolution and incidence of cirrhosis and hepatocellular carcinoma. Therefore, we studied their etiological evolution over a period of 25 years in the island of Crete. METHODS We studied 812 cases of cirrhosis (561 male, median age 69 years) and 321 cases of hepatocellular carcinoma (234 male, median age 70 years) from...

The standard deviation δm of the variations in magnitude due to microlensing is calculated for the case when the angular radius (θ s) of the source is much larger than that of the Einstein ring (θ •) for the microlens, (θ s ≥ 5θ •). An external shear γ different from zero is included in the calcuations. We find that a shear term usually has the effect of reducing the value of δm, and in all cas...

Using physician training, board certification and experience to measure physician quality, we find that cardiac patients who are treated by physicians from top ranked schools and residency programs are significantly less likely to die within the hospital than those treated by physicians from lower quality schools and residencies. This is true for all cardiac cases, within procedures like PTCA a...

We present long-slit LRIS/Keck spectroscopic observations of the gravitational lens system 0957 + 561. Averaged over all of our data, the rest-frame velocity dispersion v of the central lens galaxy G1 is v = 279 12 km s ?1. However, there appears to be a signiicant decrease in v as a function of distance from the center of G1. Within 0: 00 2 of the center of G1, we nd the average v = 316 14 km ...

In recent years odds ratios have become widely used in medical reports—almost certainly some will appear in today’s BMJ. There are three reasons for this. Firstly, they provide an estimate (with confidence interval) for the relationship between two binary (“yes or no”) variables. Secondly, they enable us to examine the effects of other variables on that relationship, using logistic regression. ...
