The patients were seen ﬁrst in the outpatient department and, after their stay in the hospital for operative or nonoperative treatment, returned to it for follow-up care or observation. Hence, he, as well as all of his associates, attended the outpatient clinic. The clinic hours ran from one to three in the after- noon, and so prompt was his arrival that watches could be set at one o’clock when he entered the hospital. He had little patience with an assistant who came late or who offered excuses for ir- regular attendance. In this, as in so many other respects, he set his assistants an excellent example. Whitman loved orthopedic surgery and sought continuously and zealously to advance it. To those who saw him and worked with him 4 or 5 days a week, he seemed to be thinking of nothing but orthopedics.

Bladder neck injections with bulking agents have a less reliable record in this difficult group discount allegra 180 mg on-line allergy treatment nursing. Artificial urinary sphincters (AUS) have an excellent record of continence buy generic allegra 120 mg on line allergy symptoms loss of voice, but there is a higher attrition rate in paraplegics due to infection or cuff erosion, especially if ISC is undertaken regularly. Placement around the bulbar urethra should be avoided in patients confined to a wheelchair, and impotence frequently complicates cuff placement in the membranous position. For both male and female paraplegic patients the bladder neck is therefore the optimal site for AUS cuff placement.

Most patients with good hand function manage the technique, though paraplegic females have more difficulty accessing their urethra. This may be sufficient to cause them to abandon attempts in favour of long-term suprapubic catheterisation. Since Mitrofanoff first described his technique in children, the procedure has been adapted to other circumstances, including stomal intermittent self-catheterisation in the paraplegic wheelchair-bound female patient. Even in tetraplegic patients with limited hand function stomal ISC is sometimes feasible with careful siting of the channel. In those patients who have undergone a Mitrofanoff procedure, stomal ISC is usually regarded as preferable to urethral catheterisation, and females whose native urethra remains in situ and who have a stoma almost never catheterise their own urethra. Complications of the procedure are irritatingly frequent though rarely life-threatening. Minor “plastic” procedures for stomal stenosis are required in up to 30% of cases and complete channel revisions for leakage or failure are necessary in 15%.

Nurses need to recognise that patients will spend a long time in hospital, probably between four and nine months. Most patients are male (4:1 men to women) aged between 15 and 40 years, but an increasing number of older people are sustaining injuries. Patients will initially be very dependent on others, and those with high lesions or from the older age group may continue to be dependent and have a disappointing level of neurological recovery and functional outcome.

Frank Holdsworth was born and brought up in Bradford and, apart from his years of training, ﬁrst at Cambridge, where he was an exhibitioner, and then at St. George’s Hospital in London, he spent the whole of his professional life in Shefﬁeld.

Indeed, he was always faintly surprised at ﬁnding himself famous and sought after, and although he knew for years that the writing was on the wall, he refused to make any concessions. To the despair of friends and medical advisers alike, he continued to drive himself as hard as ever in the many high ofﬁces to which he was called—President of the British Orthopedic Association, Senior Vice President of the Royal College of Surgeons of England, Examiner to the College and to many universities apart from his own, and a much sought after lecturer in many parts of the world. Even in his last year he visited the United States twice and on the last occasion was made an Honorary Fellow of the American College of Surgeons—an honor very rarely awarded to surgeons outside that country. His knighthood in 1967, followed by a professorship in 1969 in his own university, made a ﬁtting climax to a brilliant career.
