1. The importance of early relief of scar disabilities of the hand is emphasized–that is, before joint changes are established. 2. The part of early wound healing, early function and correct use of physiotherapy in preventing and minimizing scar disabilities of the hand is stated. 3. The “hand grenade” type of injury is described and used as a basis to describe the principles of an effective scar excision and replacement by a full-thickness skin graft. 4. A “through” type of hand wound is described in so far as scar effects are concerned. The principles of effective treatment by (a) scar excision and rearrangement for small scars and (b) scar excision and direct flap replacement for large scars are set out. 5. Other types of scar disability and their treatment are indicated– namely, web scars, adherent scars of fingers and burn scars. 6. A plea is made for the full application of plastic surgery to obtain better results from all hand wounds. 相似文献

INTRODUCTION: To plan for future acceptance and implementation of computer-related technology, it is necessary to understand orthodontists' current perceptions and attitudes toward emerging technologies. METHODS: An anonymous, self-administered, mail-out survey of Canadian orthodontists was conducted. The response rate was 45.6% (304/667). RESULTS: Most orthodontists indicated that computer technology could improve current practice efficiency and quality of patient care. Only 15% reported that digital models are quite or very useful; 73.6%, 69.1%, 55%, and 37.4% agreed or strongly agreed with using digital and electronic technology to consult with other dental specialists, other orthodontists, general dentists, and the public, respectively. Cost of the technology was reported as a significant or insurmountable obstacle by 54% of the respondents. Interprovincial legislation, unclear consultation remuneration guidelines, and lack of comfort with the technology were not perceived as significant obstacles. Only 36% reported security or privacy issues as a significant or insurmountable obstacle. CONCLUSIONS: Canadian orthodontists seem to view digital and electronic technology as useful and capable of improving their offices' efficiency and production. Although they are sensitive to some potential obstacles, they are willing to overcome these and incorporate the technology into their practices. 相似文献

The study presented here was performed in order to create a rule that identifies subjects at high risk for invasive candidiasis
in the intensive care setting. Retrospective review and statistical modelling were carried out on 2,890 patients who stayed
at least 4 days in nine hospitals in the USA and Brazil; the overall incidence of invasive candidiasis in this group was 3%
(88 cases). The best performing rule was as follows: Any systemic antibiotic (days 1–3) OR presence of a central venous catheter
(days 1–3) AND at least TWO of the following—total parenteral nutrition (days 1–3), any dialysis (days 1–3), any major surgery
(days −7–0), pancreatitis (days −7–0), any use of steroids (days −7–3), or use of other immunosuppressive agents (days −7–0).
The rate of invasive candidiasis among patients meeting the rule was 9.9%, capturing 34% of cases in the units, with the following
performance: relative risk 4.36, sensitivity 0.34, specificity 0.90, positive predictive value 0.01, and negative predictive
value 0.97. The rule may identify patients at high risk of invasive candidiasis.
Results of this project were partially presented at Focus on Fungal Infections 14, New Orleans, LA, USA, 2004. Abstract no.
