A comparison of two feeding methods in the alleviation of diarrhoea in older tube-fed patients: a randomised controlled trial.

OBJECTIVE: to compare the effect of two feeding methods on older tube-fed patients suffering from diarrhoea. DESIGN: randomised controlled study. SETTING: geriatric wards in a regional hospital. SUBJECTS: 105 patients over the age of 60 who developed diarrhoea while on intermittent bolus tube feeding. METHODS: subjects were randomised either to switch to continuous tube feeding or to continue with intermittent bolus tube feeding for 3 days, with some extended to 5 days. Incontinence pads were inspected 6 times per day by independent observers. Each motion was evaluated using a validated score according to its volume and consistency. Stools were sent for pathogen culture and Clostridium difficile cytotoxin assay. Those with positive assays were excluded from analysis. Gastric aspirations were performed at regular intervals and significant residual volumes recorded. RESULTS: 86 patients completed the study. Twelve patients (14%) were excluded due to positive CD stool assays. Seventy-four patients were entered into analysis. The median diarrhoea scores of the continuous infusion group and the intermittent bolus group were: day 0 (12 versus 10, P=0.18), day 3 (4 versus 6, P=0.23) and day 5 (5 versus 4, P=0.83) respectively. There was no statistical difference between the two groups. Two patients in the continuous infusion group (n=37) and 4 patients in the intermittent bolus group (n=37) had significant gastric residual volumes. The incidence did not differ significantly. CONCLUSION: contrary to common belief and recommendation, we could not find a significant difference between the continuous feeding method and the intermittent feeding method in the alleviation of diarrhoea in tube-fed patients. We do not recommend routine switch to continuous pump feeding in the management of tube-fed patients suffering from diarrhoea.

Treatment of organ confined prostate cancer with third generation cryosurgery: preliminary multicenter experience.

PURPOSE: Cryosurgical ablation of the prostate is 1 approach to the treatment of localized prostate cancer. Third generation cryosurgery uses gas driven probes that allow for a decrease in probe diameter to 17 gauge (1.5 mm). The safety, morbidity and preliminary prostate specific antigen (PSA) results of 122 cases are reported. MATERIALS AND METHODS: A total of 106 patients have undergone percutaneous cryosurgery using a brachytherapy template with at least 12 months of PSA followup. Immediate and delayed morbidities were evaluated. PSA results at 3 and 12 months were recorded, and failure was defined as the inability to reach a nadir of 0.4 ng/ml or less. RESULTS: Complications in patients undergoing primary cryosurgery included tissue sloughing (5%), incontinence (pads, 3%), urge incontinence/no pads (5%), transient urinary retention (3.3%) and rectal discomfort (2.6%). There were no cases of fistulas or infections. Postoperative impotence was 87% in previously potent patients. For patients who underwent salvage cryosurgery there were no fistulas reported and 2 (11%) patients required pads after salvage cryosurgery. A total of 96 (81%) patients achieved a PSA nadir of 0.4 ng/ml or less at 3 months of followup, while 79 of 106 (75%) remained free from biochemical recurrence at 12 months. A total of 42 (78%) low risk patients (Gleason score 7 or less and PSA 10 or less) remained with a PSA of 0.4 ng/ml or less at 12 months of followup, compared to 37 (71%) high risk patients. All patients were discharged within 24 hours. CONCLUSIONS: After a followup of 1 year 3rd generation cryosurgery appears to be well tolerated and minimally invasive. The use of ultrathin needles through a brachytherapy template allows for a simple percutaneous procedure and a relatively short learning curve. A prospective multicenter trial is ongoing to determine the long-term efficacy of this technique.

Is there a risk of cross-infection from laundered reusable bedpads?

The risk of cross-infection from reusable incontinence bedpads was assessed by determining their microbial content after one night's use by incontinent adults and after laundering using the standard foul wash procedure specified by the NHS Executive (NHS E, 1995) (which includes heat disinfection at 71 degrees C for 3 minutes). Measurements were made on a total of 145 bedpads from five different product designs. It was found that effective laundering destroyed all known pathogenic organisms, although some commensal flora were isolated in small numbers (mean 12.2 colony forming units/ml). It is concluded that laundering reusable incontinence pads using the foul wash procedure leaves pads safe for multiple patient reuse with no demonstrable risk of cross-infection.

Patient-reported complications after cryoablation therapy for prostate cancer.

To define the patient-reported complications after cryoablation therapy for prostate cancer and to compare these results to previously published patient-reported complications for radical prostatectomy and external beam irradiation. A questionnaire similar to previously published patient-reported complication studies was sent to the first 290 patients treated by cryoablation therapy at our Institution. The questionnaire was returned by 267 patients. Forty-four patients were excluded from analysis because of prior irradiation, transurethral prostatectomy, or cryoablation, resulting in a study group of 223 patients. Of the 208 patients with good urinary control preoperatively, 9 (4.3%) patients used incontinence pads after cryoablation. Seven of the 8 patients who used one pad daily reported leakage of only a few drops. Impotency, defined as an inability to obtain erections adequate for vaginal penetration, occurred in 85% of men who were potent preoperatively. Urethrorectal fistula occurred in 1 patient (0.4%). Bladder outlet obstruction caused by stricture of sloughed necrotic prostatic tissue required dilation or transurethral resection in 10% of patients. Scrotal swelling, penile tingling, and pelvic pain occurred in 18, 15, and 12% of patients, respectively; typically, these resolved spontaneously within 3 months. Patient-reported complications for cryoblation compared favorably to those reported for radical prostatectomy and external beam irradiation. Patient satisfaction was high; 96% of patients reported that they would choose cryosurgery as a treatment option again.

Experimental and theoretical study of the spread of fluid from a point source on an inclined incontinence bed-pad.

The spread of fluid from a localized source on to a flat fibrous sheet is studied. The sheet is inclined at an angle, alpha, to the horizontal, and the areal flux of the fluid released is Qa. A new experimental study is described where the dimensions of the wetted region are measured as a function of time t, Qa and alpha (>0). The down-slope length, Y, grows according to Y approximately (Qa t)(2/3) (sin alpha)(1/3); for high discharge rates and low angles of inclination, the cross-slope width, X, grows as approximately (Qa t)(1/2), while for low discharge rates or high angles of inclination, the cross-slope transport is dominated by infiltration and X approximately 2(2Ks psi* t)(1/2), where Ks is the saturated permeability and psi* is the characteristic value of capillary pressure. A scaling analysis of the underlying non-linear advection diffusion equation describing the infiltration process confirms many of the salient features of the flow observed. Good agreement is observed between the collapse of the numerical solutions and experimental results. The broader implications of these results for incontinence bed-pad research are briefly discussed.

Interventions led by nurse continence advisers in the management of urinary incontinence: a randomized controlled trial.

BACKGROUND: The short-term efficacy of combined lifestyle and behavioural interventions led by nurses in the management of urinary incontinence has not been rigorously evaluated by randomized controlled trial. We conducted a 6-month randomized controlled trial to determine whether a model of service delivery that included lifestyle and behavioural interventions led by "nurse continence advisers" in collaboration with a physician with expertise in continence management could reduce urinary incontinence and pad use in an outpatient population. We also aimed to evaluate the impact of this approach on subjects' knowledge about incontinence and their quality of life. METHODS: We used advertising in the mainstream media, newsletters to family physicians and community information sessions in 1991 to invite volunteers who were 26 years of age or older and suffered from incontinence to participate in a randomized controlled trial. Men and women who met the eligibility criteria were randomly allocated to receive either counselling from specialized nurses to manage incontinence using behavioural and lifestyle modification sessions every 4 weeks for 25 weeks or usual care. Symptoms of incontinence and the use of incontinence pads were the primary outcome measures. RESULTS: Using sealed envelopes, 421 patients were randomly allocated to the treatment or control groups. On average, patients in the treatment group experienced 2.1 "incontinent events" per 24 hours before treatment and 1.0 incontinent event per 24 hours at the end of the study. Control patients had an average of 2.4 incontinent events per 24 hours before the study and 2.2 incontinent events per 24 hours at the end of the study. The mean decrease in events in the treatment group was 1.2 and in the control group 0.2 (p = 0.001). Pad use declined from a mean of 2.2 per 24 hours before randomization in the treatment group to 1.2 per 24 hours at the end of the study, compared with 2.6 pads per 24 hours in the control group at the start of the study and 2.4 per 24 hours at the end. Pad use per 24 hours decreased on average by 0.9 pads in the treatment group and 0.1 in the control group (p = 0.021). INTERPRETATION: Behavioural and lifestyle counselling provided by specialized nurses with training in managing incontinence reduces incontinent events and incontinence pad use.

Validity of the incontinence severity index: comparison with pad-weighing tests.

The incontinence severity index (ISI) consists of two questions, regarding frequency and amount of leakage. It categorizes urinary incontinence (UI) into slight, moderate, severe, and very severe. The purpose of this study was to test its validity. The index was compared with the results of pad-weighing tests performed by 200 incontinent women referred to a hospital clinic and 103 at a primary care incontinence clinic. Inconvenience was scored by a six-level Likert scale. Mean pad-weighing results (grams per 24 hours, 95% confidence intervals) were 7 (4-10) for slight, 39 (26-51) for moderate, 102 (75-128) for severe, and 200 (131-268) for very severe UI. Spearman's correlation coefficient for pad-weighing results and severity index was 0.58 (p<0.01), and inconvenience increased significantly with increasing severity. The ISI demonstrated good criterion validity against 24-h pad tests. Good construct validity was indicated by a clear link between ISI and inconvenience.

Frequency volume charts: an indispensable part of lower urinary tract assessment.

Frequency volume charts (FV charts) are widely used by those interested in lower urinary tract function. However, there has been little systematic work on the value and design of FV charts as they have evolved over the years as clinical tools rather than as research instruments. Although FV chart design has developed over the last 20 years, there is no standard and charts vary from simple frequency charts up to urinary diaries which record not only frequency, volume, urge episodes, pad usage and fluid intake, but also the patients' activities in relation to their lower urinary tract symptoms. Studies have shown that charts can be relatively complex and still be acceptable to patients, providing proper instruction is given, either by written advice or at face to face interviews. The correlations between the answers to simple questions concerning frequency and nocturia and the data extracted from FV charts are variably strong: nocturia, pad usage and incontinence episodes correlate well, whereas urinary frequency correlates less closely. A number of conclusions on frequency volume charts can be made. The chart is best kept for 7 days in order to cover both work and leisure periods. The daytime should be separated from the night-time, and this is particularly important in assessing older patients with possible nocturnal polyuria. Addition of voided volume measurement to the frequency chart allows the construction of a simple classification of FV charts. This classification links the characteristics seen on the FV charts with particular lower urinary tract dysfunctions. Whilst this classification gives a guide to the patient's possible diagnosis, the overlap between symptomatic groups and normal controls is large. FV charts have an important role in objectively, recording patients' symptoms, both as a base line and after therapeutic interventions. They are particularly important in everyday clinical use as a vital part of bladder training. In the research field they are important in providing objective evidence of changes in subjective symptoms in a treatment group as opposed to the placebo group. They have been particularly valuable in the evaluation of new drugs for the treatment of detrusor overactivity and benign prostatic obstruction. Most FV charts rely on pen and paper. However in the computer age the possibility of computerising the FV chart is attractive, but as yet not fully evaluated. At present it is advised that a simple frequency volume chart with the additional recording of incontinent episodes, pad usage and overall assessment of fluid intake is used for routine clinical use. In a research setting urinary diaries may add significant additional information, allowing a more complete evaluation of novel therapies.

Pad test by mail for home evaluation of urinary incontinence.

AIMS: To present a simple, cost-effective, and convenient method of home pad test using the mail system and evaluating change in pad weight over time. MATERIALS AND METHODS: A series of nine kinds of commonly available commercial brands of urinary incontinence pads ranging from thin liners less than 10 g in dry weight to large diapers weighing over 100 g each were assembled. Two or three of each variety were individually weighed on an OHAUS LS2000 Portable Standard scale accurate to +/- 1 g. The pads were then wet uniformly with 20 cc of saline, placed individually in sealable plastic bags, sealed, and reweighed. Random groups of three pads were mailed by standard 1st class mail to the Urocenter of New York. The sealed pads were reweighed at 8 and 14 days from the original wetting. Concurrently, ten incontinence pads soiled with urine were similarly examined to confirm that there would be no detectable difference between urine and saline for the purpose of the study. In the second part of the study, 20 pads of the same type (13 inch-long pads with absorbent gel) were divided into 4 groups of 5 pads; each group was uniformly wet with 5, 10, 20, or 50 g of saline. These pads were mailed and reweighed at 7 and 14 days from the initial wetting. RESULTS: Twenty-four pads were used in the first part of the study. The dry weights of 22/24 (92%) of the pads were within 2 g of the average weight for their brand. At the first reweighing, 22 pads (92%) weighed within 2 g of their initial wet weights (Fig. 1). Only two pads on day 8 differed substantially from their initial weights: one pad appeared to have lost 4 g and another one 9 g. On day 14, 23/24 pads remained within 1 g of their day 8 weight and 1 differed by 2 g, and the total weight of the 24 pads on day 14 was only 4 g different from their initial weight (P = 0.71, Fig. 1). The soiled pads exhibited weight changes that were indistinguishable from the saline pads. The average cost of mailing the pads by 1st class mail was $4 and the average length of time in the mail was 5 days +/- 1 day. In the second part of the study, 18/20 pads had lost less than 1 g at 1 week, and at 2 weeks, 19/20 had lost less than 2 g when compared to their initial weights (Fig. 2). One pad had lost 3 g. Pads in the low volume groups (5 and 10 g) lost an average of 1.4 and 1.2 g, respectively, while pads in the high volume groups (20, 50 g) lost an average of 1.8 and 2 g at 2 weeks. CONCLUSIONS: Dry pads of any single brand have a relatively standard weight that varies insignificantly between pads. Up to 2 weeks of delay in the weighing of individually sealed pads does not significantly affect the clinical measurement of weight at a variety of low (5 g) or high (50 g) volumes of simulated incontinence. Home pad test using the mail system is a feasible, inexpensive, and clinically accurate method of evaluating incontinence. Patients can be instructed in techniques for home pad test, allowing for greater compliance, and convenience for both physicians and patients.

Pad test with fixed bladder volume in urinary stress incontinence.

A pad-weighing test of urinary stress incontinence during a set program of physical exercises is presented. The test was begun at a fixed bladder volume (75% of maximum capacity) and was repeated once. The duration of the exercises was approx. 15 min. Leakage was greater in the second test, but statistical analysis showed highly significant intraindividual correlation between the two amounts. Degree of leakage was not correlated to subjective assessment of incontinence. The test can be done as part of a routine urodynamic investigation.

In control with incontinence aids.

Incontinence is a common condition affecting people of all ages. Many can be cured and all can benefit from appropriate treatment and management. Despite huge growth in this market, many products are neither appealing nor acceptable to those people who have to use them. Whenever practical, it is best that the choice of aid should be a collaborative decision between the user and the carer.
