Prevalence of Gardnerella vaginalis: an estimate.

To assess the prevalence of Gardnerella vaginalis in the community 300 women aged 16-59 were randomly selected from a general practice's age-sex register and invited to attend for a health check. Out of 282 women who were eligible to attend, 192 did so. They were asked whether they had any vaginal symptoms, and swabs were taken from 182 women for culture for G vaginalis. Sixty women were positive for G vaginalis, of whom 26 had symptoms. Infections with G vaginalis may be present in women who have no symptoms. By careful questioning, examination, and side room testing general practitioners may be able to diagnose these infections in such women consulting them for other reasons.

Contribution of Gardnerella vaginalis to vaginitis in a general practice.

In a study of 154 adult women who presented to their general practitioner with vaginal symptoms 30 (20%) had Gardnerella vaginalis on its own and 51 (33%) had G vaginalis in combination with anaerobes or known pathogens. Thirty one (20%) patients were culture negative. Those who were culture negative had fewer symptoms and signs of vaginitis than those with G vaginalis alone or G vaginalis plus anaerobes. Those with known pathogens had more symptoms and signs than those with G vaginalis alone or G vaginalis plus anaerobes. Those with known pathogens plus G vaginalis had the most severe signs and symptoms of vaginitis. It is concluded that G vaginalis can cause vaginitis on its own, and it makes vaginitis worse when present with other organisms. G vaginalis was also found in 30 (21%) of the 138 control patients who, although they presented "asymptomatically," had worse signs than control patients without G vaginalis. It seems that G vaginalis can occur in a spectrum ranging from the uncomplaining patient to those with severe vaginitis.

Irritable urethral syndrome: follow up study in general practice.

Two years after a microbiological study of the urethral syndrome 25 of 31 women had had further symptoms, but only two had sought medical help for their symptoms in the year after the study. Analysis of patients' records showed that women with the urethral syndrome had higher consultation and sterilisation rates and more psychosomatic symptoms and relationship problems than matched control patients. Using the Nottingham health profile women with the urethral syndrome were more likely to mention that health problems affected their sex lives and were more likely to see themselves as having health problems than control patients. Women who have the urethral syndrome are considerable drain on the doctor's time, and management needs to be directed towards the anxious patient who makes such demands. Seeing the condition as the "irritable urethral syndrome" may help both doctor and patient to recognize the psychosomatic aspect of the problem.

Clinical judgment in the diagnosis and management of frequency and dysuria in general practice.

In a study of 40 women with the urethral syndrome and 46 women with conventional urinary tract infection, none of whom was pregnant, general practitioners predicted the diagnosis correctly before the report on the midstream urine specimen was received, as evidenced by their management. They seemed to do this by balancing the symptom of dysuria with the psychological make up of the patient: patients with the urethral syndrome suffered appreciably less dysuria than patients with urinary tract infection; patients with the urethral syndrome suffered appreciably more psychological illness. This ability to distinguish between the two disorders has important clinical and economic implications.

A comparative trial of pivmecillinam/pivampicillin and amoxycillin/clavulanate in the therapy of urinary tract infection in a general practice population.

Fifty-eight patients seen in general practice presenting with symptoms of acute urinary tract infection were entered consecutively into an open randomized trial of 200 mg pivmecillinam plus 250 mg pivampicillin twice daily or 250 mg amoxycillin plus 125 mg clavulanate 3-times daily for 5 days. The results were analyzed in 41 patients with significant bacteriuria (23 on pivmecillinam/pivampicillin and 18 on amoxycillin/clavulanate). Both antibiotic combinations produced good overall bacteriological cure, but there were a considerable number of persisting symptoms despite the absence of significant bacteriuria. Eight patients in the pivmecillinam/pivampicillin group and 5 in the amoxycillin/clavulanate group had side-effects, principally thrush, vomiting and abdominal pain, and 1 patient from each group ceased treatment for this reason. Sensitivity profiles of urinary isolates (41 trial, 135 non-trial) to both combinations and to ampicillin and mecillinam showed that the majority were fully sensitive to amoxycillin/clavulanate and to a lesser extent to pivmecillinam/pivampicillin; resistance was highest to ampicillin.
