Identifying types of female incontinence with retrograde urethrocystography

The most specific radiographic findings characterizing stress incontinence (SI) on upright retrograde urethrocystography include replacement of a flat or rounded bladder base with a concave funnelled base; patency of the bladder neck with contrast material pooling in the proximal urethra; the descent of the intravesical Foley balloon beyond the internal meatus and into the proximal urethra. We found that neither a cystocele nor the dependent position of the urethra at the bottom of the bladder were diagnostic of SI if the above stigmata were absent. On the other hand the defect of urgency incontinence (UI) is functional. The bladder can usually be filled by retrograde urethral infusion (though in severe UI this may not be the case). An alert technician can frequently obtain a film when the patient is experiencing uninhibited voiding. The finding of contrast material throughout the urethra, in the distal urethra alone, or in the parameatal area is strongly suspicious for UI, especially when trabeculation is also seen. These findings in association with the stigmata of SI give warning of combined SI and UI.     

Randomised controlled trial of anti-smoking advice in pregnancy. 1977.

In a randomised controlled trial intensive individual anti-smoking advice given in parallel with hospital antenatal care did not influence the outcome of pregnancy. The belief that retardation of fetal growth caused by maternal smoking occurs in late pregnancy is not well based, and the advice may not have been given in time to be effective. Other possible interpretations of the results, that maternal smoking is merely an index of some other factor that retards growth or that those counselled did not reduce their smoking sufficiently to influence outcome, cannot be excluded.     

Serving seniors better: service guidelines for supermarkets

Objective: Generate a list of service guidelines to enable supermarket managers to accommodate the needs of their older customers. Methods: Focus groups and a national telephone survey were conducted with Australian seniors to generate 10 service guidelines for supermarkets. Results: The 10 guidelines produced are considered to be of significant importance by Australian seniors, with some apparent differences in importance and relevance ratings between older and younger seniors, and males and females. Conclusions: Seniors have distinct service preferences when grocery shopping and their needs require special attention in the supermarket environment. In particular, they feel strongly about the quality of staff and equipment with which they come into contact.     

Colon perforation during colonoscopy: surgical versus conservative management

A survey of endoscopy units in the West Midlands, UK, was undertaken to ascertain the management of colonic perforation during colonoscopy. Fifteen perforations were reported from a total of 17,500 colonoscopies performed in 14 units (a rate of 0.09 per cent). In seven patients the diagnosis was suspected or diagnosed immediately and in the remaining eight 2-72 h later. Four patients with associated pathology (carcinoma, Crohn's disease, ulcerative colitis and a polyp) had resection and primary anastomosis. Seven patients had a simple oversew, four of these having had a delayed diagnosis. In four cases the site of perforation was not identified, but only one patient had conservative treatment. Three patients had drainage and a defunctioning colostomy. There was no significant morbidity following treatment. It is recommended that patients who have had a good bowel preparation should be treated conservatively unless there is a large perforation or an underlying carcinoma.     

Profile of denials of durable medical equipment for SCI patients by third party payers

The difficulty in obtaining approval for payment of durable medical equipment by third party payers has impeded the rehabilitation program and discharge planning of many spinal cord patients throughout the country for many years. To gain some insight as to the number and level of patients affected, the kinds of equipment denied, the reasons given for the denial, which third party payers were mostly involved and how the patient and his/her family managed to cope or resolve this problem, a survey was undertaken. Letters were sent to 259 members of the American Spinal Injury Association (ASIA) asking them to list representative cases where requests for equipment deemed necessary were denied. Twenty-eight responses from different institutions were received from sixteen states describing 110 patients and 180 pieces of durable medical equipment denied in 1984 and 1985. Manual wheelchairs, motorized wheelchairs, shower/commode chairs, and environmental control units were the four most common equipment items denied by the third party payers. Government agencies ie., Medicaid, Medicare, Vocational Rehabilitation Departments and State Crippled Children's Services were the most frequent deniers, comprising 54% of the total sample. They were followed by private insurance (31%) and Workman's Compensation (3%). By far, the two most common reasons given for denials were: it was not covered by the insurance policy (38%) and it was not medically necessary (30%). Ninety (90) pieces of equipment (50%) were eventually obtained, most often by charity, or through the patient's family resources.     

Polymorphonuclear leucocyte motility in patients with severe burns

Chemotaxis, chemokinesis and cellular orientation were measured for unstimulated and 10(-7) n-formyl methionyl leucyl phenylalanine (F-met-leu-phe) stimulated polymorphonuclear leucocytes (PMNS) of nine patients with recent 10-80 per cent burns using a computer-assisted image analysis technique. The technique records PMN movement, as viewed with a phase-contrast microscope on videotapes, and then uses computer programs to calculate the speed and direction of up to 50 PMNS over a 5-min period. Orientation was determined visually. Cellular adherence was also measured by attachment methods. PMNS from burn patients were slower (av. speed 16.8 microns/min), responded less well to F-met-leu-phe (av. speed 20.9 microns/min, av. McCutcheon index 0.32), were less often oriented towards the chemoattractant (av. 39 per cent) and were more adherent (av. 50 per cent) than control cells (av. speed 21.8 microns/min; av. speed F-met-leu-phe 32.2 microns/min; McCutcheon index 0.61; oriented 59 per cent adherent; 16 per cent). Thus PMNS from burn patients orient less well, are significantly slower and have less directionality in response to a chemoattractant, and are more adherent suggesting activation.     

Computed tomography in gunshot wounds to the neck: Can we predict vascular injury?

The purpose of this study was to evaluate the ability of helical computed tomography (CT) to detect arterial injuries in gunshot wounds to the neck. In a blinded retrospective review, 54 helical CT scans of the cervical spine were evaluated for bullet/bone fragments, subcutaneous air, bullet path, hematoma, spine fractures, and pharyngoesophageal compromise. The distance of fragments to a major vessel was calculated. CT findings that correlated significantly with major arterial injury included the presence of fragments (bullet/bone) close to a major vessel (2.5 mm) and spine fractures. Visualizing fragments <5 mm from a vessel or a transcervical bullet trajectory predicted 12 of 13 major arterial injuries. We conclude that CT clearly depicts anatomic damage. Specific findings, such as the location of fragments and bullet trajectory adjacent to a vessel and spine fractures, indicate a higher probability of vascular damage, thus directing more definitive evaluation.
