Young men presenting to a General Surgical Unit with acute epididymitis underwent microbiological investigation, including culture for Chlamydia trachomatis. The results were compared with similar investigations in an asymptomatic control population and with patients presenting to the Department of Genito-urinary Medicine with urethral discharge. Chlamydia trachomatis was cultured from 15% of patients with acute epididymitis and a further 15% had serological evidence of exposure to Chlamydia. Nearly 50% of patients attending the Genito-urinary clinic grew Chlamydia from the urethra. The background prevalence of Chlamydia in the control population was low. It is necessary to identify the significant minority of young men with acute epididymitis associated with chlamydial infection, because of the risk of pelvic inflammation and infertility in their female partners. At present this can only be achieved by submitting all young men with acute epididymitis to full microbiological investigation.
The aetiology of acute epididymitis presenting to a surgical unit in a District General Hospital is presented. Patients over 45 years old frequently have a coliform urinary tract infection which may be associated with bladder neck obstruction. These patients require treatment with a suitable antibiotic (Co-trimoxazole) and further investigation. This condition occurs more commonly in patients under 45 years old in whom it is not associated with urinary tract infection. We have not demonstrated significant chlamydial infection and in a double blind study the antibiotic Co-trimoxazole did not hasten recovery. In this group the aetiology remains obscure.
Insensible water loss has been studied before, during and afrer abdominal surgery of moderate severity. It has been shown that i f normal hydration is maintained there is no significant change in insensible water loss.
Patients who become relatively dehydrated have a signifcant fall in insensible water loss but there is noevidence that this is detrimental to their postoperative progress.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
