Audit of a multidisciplinary vulvar clinic in a gynecologic hospital.

OBJECTIVE: To perform a five-year retrospective audit of all new patients referred to a tertiary vulvar referral service. STUDY DESIGN: A review was made of the records of all new clients who attended the vulvar clinic between 1993 and 1997. Information was entered into a database and analyzed. RESULTS: Four hundred seventeen women were seen in the study period. Their ages ranged from 8 to 94 years (mean, 48.5). The most common symptoms were pruritus (44.8%), soreness (28.6%) and irritation (24.2%). Striking features were the poorly defined and lengthy histories and multiple symptomatology. Biopsies were performed in 61% of cases. Histologic diagnoses included vulvar intraepithelial neoplasia (VIN), 18.5%; nonneoplastic epithelial disorders, 16.8%; and carcinoma, 8.1%. Clinical diagnoses included dermatitis in 10% and normal vulva in 7.7%. The remaining cases represented a wide variety of dermatologic, pain and gynecologic conditions. There was a 95% correlation between the clinical and histologic diagnosis of VIN and 87% in lichen sclerosus. In 64.7% of women, treatment resulted in an improved outcome, 13.7% reported no improvement, and 1.6% cases deteriorated during treatment; 19.9% were lost to follow-up. CONCLUSION: Provision of a multidisciplinary vulvar clinic in a tertiary setting provides an invaluable service for both primary and secondary clinical practitioners. The increasing demand for our services has created lengthy waiting times. The chronic nature of many vulvar diseases results in long-term follow-up of many women. Patient selection bias has developed as a consequence of the interests of the clinicians involved.

Personality testing in 226 patients with urinary incontinence.

Two hundred and twenty-six female patients undergoing investigation for urinary incontinence completed the Eysenck Personality Inventory questionnaire. The results of the questionnaire were correlated with the symptomatology and urodynamic findings. Incontinence and neuroticism were found to be related. No special relationship was found between neuroticism and detrusor overactivity, although this has been reported in other smaller series.

The Urilos recording nappy system.

A technical and clinical evaluation of the Urilos recording nappy system is presented. The recording pads were calibrated to determine the variation between and within batches of 25 pads supplied by the manufacturer. Fifty patients were assessed by this system for periods of 2 to 7 h. The results show that the system is useful in the verification of patient histories, although it is difficult to obtain a quantitative measure of urine loss.

Calibration↗

A technical and clinical evaluation of the Disa uroflowmeter.

This investigation reveals that there is a marked reduction in the rotational speed of the transducer disc as the stream flowrate is increased, although the non-linearity is partly reduced by electronic compensation within the instrument. The inaccuracy at low flowrates is probably unimportant in routine clinical applications. However, significant errors are recorded at high flowrates when the stream strikes the grid intersections or when the point of impact is close to the edge of the rotating disc. For these reasons, it is desirable that the patient should avoid micturating directly on to the grid. To obtain acceptable clinical recordings, an instrument time constant of 0-5 sec must be used. Although some characteristic tracings can be identified, the clinical measurements indicate that the effects of the volume voided and stream movement must be taken into consideration when the flow patterns are being interpreted.

Detection of urine loss using the Exeter recording nappy and other similar devices.

A technical evaluation of the Exeter recording nappy has been carried out with particular reference to (a) linearity, (b) reproducibility of calibration, (c) the effect of variation in the position of moistened zones produced by consecutive leakages and (d) the effect of variation in the electrical conductivity of the liquid detected. The clinical use of the nappy is also discussed. A miniature alarm coupled to a similar pad arrangement has been developed as a training system for the geriatric incontinent patient and patients with neurogenic bladders. A 'pad and pant' version of an enuresis alarm has also been designed which had advantages over the conventional under-sheet type.

Maximum perineal stimulation for urinary incontinence.

Maximum stimulation of the pelvic floor has been advocated for the treatment of urinary incontinence associated with defective urethral closure mechanisms. Information in the literature was imprecise as to what constitutes a maximum stimulation. With one exception, published results are not encouraging when analysed. None of our 19 patients showed improvement. One had enhanced contraction when using an anal plug electrode following maximum stimulation, and this effect may warrant further study.
