The lowest recurrence rates after inguinal hernia repair have been achieved by specialized hernia clinics. The Shouldice repair achieves success through application of a meticulous standardized operation carried out by specialist hernia surgeons. In a trial designed to rule out surgeon-dependent variables, 322 inguinal hernias were randomized prospectively to Shouldice repair or plication darn. Fifteen general surgeons operated on 322 patients. Fourteen surgeons in training not familiar with Shouldice repair received constant supervision for six repairs before independent operation. The mean (s.d.) patient age was 58.3(1.5) (range 20-84) years for Shouldice repair and 57.0(1.2) (range 18-85 years) for plication darn. The sex ratio (M:F) was 17:1 and right side to left side ratio 1.8:1. Six-week complication rates for wound infection (Shouldice repair, 5 per cent; plication darn, 4 per cent) and haematoma (Shouldice repair, 7 per cent; plication darn, 5 per cent) were similar in both groups. There were a similar number of sliding hernias in the Shouldice repair (14) and plication darn (20) groups. After a mean follow-up of 30 (range 24-48) months there were seven recurrences in the Shouldice group and four in the plication darn group (P > 0.05). The recurrences suggest that additional supervision of junior surgeons is required during the Shouldice repair learning period.  相似文献

This study compared clinical outcomes and nursing labor costs associated with (a) balsam Peru, hydrogenated castor oil, and trypsin (BCT) ointment; (b) BCT + Other; and (c) Other treatments in 2014 wound episodes occurring in 861 patients (mean 2.34 wounds/patient). Treatment with BCT ointment or BCT + Other was associated with a higher healing rate (P < .05). No Stage 1 or 2 ulcer treated with BCT ointment progressed, compared with 13.8% treated with BCT + Other and 13.4% treated with Other. The reported mean duration of treatment and time to heal were shorter for ulcers treated with BCT ointment, but differences did not reach significance, possibly because of the variability in reported treatment times. Mean daily nursing labor costs were lower for treatment with BCT than Other ($50.8 vs $61.7, P < .05). These data suggest that treatment of Stage 1 or 2 ulcers with BCT may be associated with shorter treatment time and time to heal and a potential reduction in treatment-related nursing labor costs.  相似文献

Dislocation after total hip arthroplasty. Causes and prevention   总被引:31,自引:0,他引:31  
In this prospective study, a technique of positioning the acetabulum by bony landmarks of the pelvis in the standing position was developed using a standing lateral preoperative roentgenogram with the X-ray tube centered over the trochanter. Since 1984, 441 total hip arthroplasties (THAs) were done through the posterior approach with a 1.14% dislocation rate through 1988 and no dislocations in 1989. To prevent impingement and dislocation, it was determined that the safest range for cup position was 30 degrees-50 degrees abduction and 20 degrees-40 degrees flexion from the horizontal. To measure postoperative cup position, a standing true lateral roentgenogram of the operated hip allowed direct measurement of cup flexion and was reproducible within 10 degrees. No special instruments are necessary for this technique, which can be used with any THA system.  相似文献

A human chromosomal translocation t(8;9) was detected using two-color fluorescence in situ hybridization with probes capable of staining the entire lengths of each of these chromosomes. The chromosome 8 probe was labeled with biotin and detected with Texas red, while the chromosome 9 probe was labeled with AAF and detected with FITC . In normal metaphase spreads, two metaphases from the proband, two red, one green and one part red and part green derivative chromosome were seen. The bicolor chromosome corresponded to translocation of a chromosome 8 segment to the distal part of the q region of one chromosome 9, as originally indicated by banding analysis. In interphase nuclei of the proband, four domains with bright fluorescence were recognized in many nuclei. Two were red, one was green, and the fourth had portions of both colors, indicating the presence of the translocation.  相似文献

Ingestion of small bones often causes oropharyngeal trauma. I present an unusual case of a potentially life-threatening haematoma of the soft palate caused by a chicken bone. To my knowledge, this is the only case reported in the English literature.  相似文献

Infectious intracavernous carotid artery aneurysms usually present with ophthalmoplegia and/or signs of cavernous sinus thrombosis. We report an unusual case in which a patient with AIDS presented with intractable epistaxis secondary to rupture of a giant infectious intra-cavernous carotid artery aneurysm. Culture of the aneurysm grew mycobacterium avium intracellulare (MAI). The patient was treated successfully by excision of the aneurysm and reconstruction of the internal carotid artery with a saphenous vein interposition graft.  相似文献

A near-patient testing facility was provided at an anticonvulsant clinic and compared with the previously offered service. Productivity was increased by over 20%, with savings in medical and nursing staff time. This saving in time is offset by increased consumable costs but still enables a significant net saving.  相似文献
