Composite graft replacement of digital tips. 2. A study in children.

This study investigated the outcome of composite graft replacement of 50 amputated digital tips in 50 children over a period of 3 years and 6 months. Eleven of 18 tips (61%) which were replaced within 5 hours survived completely while none of 32 digital tips replaced after 5 hours survived completely. This difference was highly significant. The mean delay time between amputation and replacement in the successful group was 3.9 hours and in the others was 7.2 hours. This difference was also statistically significant. The implications of the findings of this series to the use of this treatment are discussed.

Effects of a multidimensional anabolic steroid prevention intervention. The Adolescents Training and Learning to Avoid Steroids (ATLAS) Program.

OBJECTIVE: To test a team-based, educational intervention designed to reduce adolescent athletes' intent to use anabolic androgenic steroids (AAS). DESIGN: Randomized prospective trial. SETTING: Thirty-one high school football teams in the Portland, Ore, area. PARTICIPANTS: Seven hundred two adolescent football players at experimental schools; 804 players at control schools. INTERVENTION: Seven weekly, 50-minute class sessions were delivered by coaches and student team leaders, addressing AAS effects, sports nutrition and strength-training alternatives to AAS use, drug refusal role play, and anti-AAS media messages. Seven weight-room sessions were taught by research staff. Parents received written information and were invited to a discussion session. MAIN OUTCOME MEASURES: Questionnaires before and after intervention and at 9- or 12-month follow-up, assessing AAS use risk factors, knowledge and attitudes concerning AAS, sports nutrition and exercise knowledge and behaviors, and intentions to use AAS. RESULTS: Compared with controls, experimental subjects at the long-term follow-up had increased understanding of AAS effects, greater belief in personal vulnerability to the adverse consequences of AAS, improved drug refusal skills, less belief in AAS-promoting media messages, increased belief in the team as an information source, improved perception of athletic abilities and strength-training self-efficacy, improved nutrition and exercise behaviors, and reduced intentions to use AAS. Many other beneficial program effects remained significant at the long-term follow-up. CONCLUSIONS: This AAS prevention program enhanced healthy behaviors, reduced factors that encourage AAS use, and lowered intent to use AAS. These changes were sustained over the period of 1 year. Team-based interventions appear to be an effective approach to improve adolescent behaviors and reduce drug use risk factors.

Palmar bands in rheumatoid arthritis and other chronic conditions of the upper limb.

Palmar prolapse of the flexor tendons as a result of attenuation of the A1 and A2 pulleys occurs in rheumatoid arthritis and other conditions in which the joints of the fingers are chronically flexed. The flexor tendons may be palpable and sometimes visible as longitudinal bands crossing the palm. This can lead to confusion with the palmar bands of Dupuytren's disease. These bands are illustrated in a small series of patients and a serious complication of a misdiagnosis of Dupuytren's disease is presented. The pathogenesis of these palmar bands in rheumatoid arthritis is discussed.

Dupuytren's disease in children.

Although Dupuytren's disease of the hand has been reported in teenagers, it is generally considered to be a disease of adults. A series of nine children who developed Dupuytren's disease of the hand before the age of 13 years is presented. Eight had surgical removal of the diseased tissue and histological confirmation of the diagnosis before the age of 13 years and one at 14 years of age. The presence of the condition in young children and teenagers is discussed and the literature summarized.

Total middle ray amputation.

Eight patients underwent middle ray amputation with excision of the whole of the middle metacarpal and careful soft tissue repair. Excision of the base of the middle metacarpal allowed easier approximation of the index and ring rays without the tendency of these fingers to either scissor on finger flexion or to remain slightly apart. Complete removal of the middle metacarpal appears to allow the bases of the index and ring metacarpals to migrate together. The removal of the metacarpal base caused no functional problems and the technique created a good three-finger hand from both a functional and cosmetic point of view.

Radiofrequency ablation: a review of its application and nursing considerations.

Radiofrequency ablation (RFA), a therapeutic electrophysiological procedure, has become the treatment of choice for a number of cardiac arrhythmias. These arrhythmias include those of anomalous pathways, as seen in AV nodal re-entry tachycardia and Wolff-Parkinson-White syndrome, and re-entry tachycardias of atrial and ventricular origins. This paper discusses the mechanism of RFA and the physiology of re-entry circuits, and outlines the cardiac arrhythmias treated by RFA. The nursing responsibilities associated with the RFA procedure--including patient education, observation for potential complications, and other peri- and post-procedure considerations--are then addressed.

Intervention and prevention of steroid use in adolescents.

Athletes with a higher intent to use anabolic steroids were similar to students who indicated no predisposition to use steroids on economic, academic, and physical measures. They had similar understandings of anabolic steroid effects, and their self-rated understandings of how to weight train and of sports nutrition were similar. In addition, the influence of the coaches and the media and the perceived prevalence of anabolic steroid use were not different between the higher- and lower-intent students. These results demonstrated several significant differences. Higher-intent students had higher levels of alcohol and marijuana use, which suggest that those items might be tackled concurrently. These athletes had higher hostility, impulsivity, and a win-at-all-costs attitude. Despite similar physical measures, they had a high body image, but were less satisfied with their current weight. These findings underscored the importance of using nutrition and appropriate training as effective alternatives to anabolic steroids. Higher-intent students had greater peer tolerance of drug use and less parental influence not to use drugs, which implies that a peer-led small group format might be important to dispel the perceived peer tolerance. Including a parent-based component, one that emphasizes a disapproval of drug use also could be effective. Higher-intent athletes had less ability to refuse an offer of steroids. The dynamics of turning down steroids may differ from that of other illicit substances so that training in refusal skills specific to steroids is needed. These differences provide a needs assessment to identify curricular components for an intervention to permit anabolic steroid use. The sports team may be a unique educational setting because it can capitalize on peer ties, the coach's influence, and an athletes' motivation to improve, to prevent drug use, and to promote healthy behaviors.

The neurovascular Tranquilli-Leali flap.

A modification of the flap first described in 1935 by Tranquilli-Leali and described again by Atasoy et al (1970) is presented. The relative indications for use of the original and the modified flap are examined in the light of our experience of 116 flaps over a period of 4 years.

The rupture rate of acute flexor tendon repairs mobilized by the controlled active motion regimen.

A series of 233 patients with complete divisions of flexor tendons in zones 1 and 2 underwent operation following emergency admission over a period of 3.5 years. These included 203 patients with 317 divided tendons in 224 fingers injuries in zones 1 and 2 and 30 patients with 30 complete divisions of the flexor pollicis longus tendon in zones 1 and 2. All of these patients were mobilized post-operatively in a controlled active motion regimen. 13 (5.8%) fingers and five (16.6%) thumbs suffered tendon rupture during the post-operative period. Patients treated during the last year of the study were followed prospectively for a minimum period of 3 months; ten of the 16 (62.5%) fingers with zone 1 repairs, 50 of the 63 (79.4%) fingers with zone 2 repairs, all three (100%) FPL divisions in zone 1 and three of four (75%) FPL divisions in zone 2 had good and excellent results on assessment by the original Strickland criteria (Strickland and Glogovac, 1980). These results confirm the safety of this regimen as an alternative to other regimens of post-operative flexor tendon repair mobilization in zone 1 and 2 finger injuries. However, in the unmodified form used in this series, this regimen has too high a rupture rate for FPL mobilization.
