Introduction
Floating knee is a flail knee joint resulting from fractures of the shafts or adjacent metaphyses of the femur and the ipsilateral tibia. It is usually associated with several complications and mortality. This study was designed to present our experience with the treatment of this injury.Material and method
This study was performed between January 2004 and December 2014. 224 cases of floating knee injuries gathered from the 34,480 lower extremities trauma files were studied, and the target information recorded. The injuries most frequently occurred in subjects between 16 and 35 years of age (60.71%), and in male subjects (85.71%). The most frequent mechanism of injury was traffic accident (92.85%). External fixation was the common type of treatment (82.14%) in emergency or as a definitive treatment. The treatment was performed within 24?h of the trauma. We performed a 36-month follow up with clinical examination, radiographs, assessing the complications, and using the Modified Cincinnati Rating System Questionnaire (MCRSQ) and the Karlström/Olerud Score (KOS) to evaluate the progression of the outcomes.Results
Early complications included 8 cases of compartment syndrome, 60 open fractures and 24 partially amputated limbs. A total amputation was performed in 3 patients. The most common late complication was heterotopic calcifications of the knee (n?=?68, 30.6%). Good scores for MCRSQ and KOS were obtained only after patients were sent to a reference center for knee surgery.Conclusions
Our experience revealed that the complication rate associated with floatingknee injuries remains high, regardless of the performed treatment. Surgeons should focus on reducing complications while treating these severe injuries. 相似文献3.

Background and Objectives:
Routine drainage after laparoscopic cholecystectomy is still controversial. This meta-analysis was performed to assess the role of drains in reducing complications in laparoscopic cholecystectomy.Methods:
An electronic search of Medline, Science Citation Index Expanded, Scopus, and the Cochrane Library database from January 1990 to June 2013 was performed to identify randomized clinical trials that compare prophylactic drainage with no drainage in laparoscopic cholecystectomy. The odds ratio for qualitative variables and standardized mean difference for continuous variables were calculated.Results:
Twelve randomized controlled trials were included in the meta-analysis, involving 1939 patients randomized to a drain (960) versus no drain (979). The morbidity rate was lower in the no drain group (odds ratio, 1.97; 95% confidence interval, 1.26 to 3.10; P = .003). The wound infection rate was lower in the no drain group (odds ratio, 2.35; 95% confidence interval, 1.22 to 4.51; P = .01). Abdominal pain 24 hours after surgery was less severe in the no drain group (standardized mean difference, 2.30; 95% confidence interval, 1.27 to 3.34; P < .0001). No significant difference was present with respect to the presence and quantity of subhepatic fluid collection, shoulder tip pain, parenteral ketorolac consumption, nausea, vomiting, and hospital stay.Conclusion:
This study was unable to prove that drains were useful in reducing complications in laparoscopic cholecystectomy. 相似文献4.

ObjectivesThe aim of this study was to assess the motor profile of children with attention deficit hyperactivity disorder (ADHD), combined type.MethodThe case group consisted of 34 treatment-naive, male patients, aged 7–11 years, who had been diagnosed with ADHD, combined type, without comorbidities (except oppositional defiant disorder). The control group was composed of 32 age- and gender-matched, typically developing children. The evaluation was made using the Motor Development Scale, which assessed global and fine motricity, balance, body scheme, and spatial and temporal organization.ResultsThe results showed that the motor quotients in all areas studied were lower in the ADHD group than in the control group, although in most cases they represent normal values relative to the scale (53% were classified as having “normal medium” motor development, 29% “normal low”, 9% “very low”, 6% “normal high” and 3% as “lower”). Statistically significant differences between groups were observed in general motor age, general motor quotient, balance, spatial organization, and fine and global motricity.ConclusionDifficulties in motor performance were observed in the children with ADHD, combined type. The identification of such deficits may assist in the design of therapeutic protocols for the treatment of children with this type of ADHD. 相似文献

Femoral neck fractures in the elderly are frequent, represent a serious health care problem, and have a significant impact on health costs. Reconstruction options using hip arthroplasty include bipolar hemiarthroplasty (HA) and total hip arthroplasty (THA). The purpose of this review is to discuss the indications, limitations, and pitfalls of each of these techniques. 相似文献

This work is aimed to present an innovative technology for the reinforcement of beams for urban furniture, produced by in-mold extrusion of plastics from solid urban waste. This material, which is usually referred to as “recycled plastic lumber”, is characterized by very poor mechanical properties, which results in high deflections under flexural loads, particularly under creep conditions. The Prowaste project, founded by the EACI (European Agency for Competitiveness and Innovation) in the framework of the Eco-Innovation measure, was finalized to develop an innovative technology for selective reinforcement of recycled plastic lumber. Selective reinforcement was carried out by the addition of pultruded glass rods in specific positions with respect to the cross section of the beam, which allowed optimizing the reinforcing efficiency. The reinforcement of the plastic lumber beams with pultruded rods was tested at industrial scale plant, at Solteco SL (Alfaro, Spain). The beams obtained, characterized by low cost and weight, were commercialized by the Spanish company. The present paper presents the most relevant results of the Prowaste project. Initially, an evaluation of the different materials candidates for the reinforcement of recycled plastic lumber is presented. Plastic lumber beams produced in the industrial plant were characterized in terms of flexural properties. The results obtained are interpreted by means of beam theory, which allows for extrapolation of the characteristic features of beams produced by different reinforcing elements. Finally, a theoretical comparison with other approaches which can be used for the reinforcement of plastic lumber is presented, highlighting that, among others, the Prowaste concept maximizes the stiffening efficiency, allowing to significantly reduce the weight of the components. 相似文献

The effect of morphine administration on the subsequent stimulation of prolactin (PRL) secretion and the release of dopamine from tuberoinfundibular neurons was examined in this study. The administration of morphine (15 mg/kg s.c.) resulted 4 hr later in suppressed serum PRL concentrations. In addition, the increase in serum PRL concentrations induced by restraint stress was attenuated greatly in rats treated 4 hr earlier with morphine. The morphine-induced attenuation of the PRL response to restraint stress was time-dependent and dose-related. The suppressive effect of morphine on PRL secretion was observed 3 to 6 hr after its administration and at doses of 10 to 20 mg/kg. A single injection of morphine also resulted 4 hr later in an attenuation of the PRL response to a second injection of morphine (7.5 mg/kg); however, the increase in serum PRL concentration produced by alpha-methyltyrosine (250 mg/kg) was unaltered by prior morphine administration. The suppressive effect of morphine on PRL secretion was not observed in rats treated with the opiate antagonist naloxone (2.5 mg/kg). Associated with the delayed suppressive effect of morphine on serum PRL concentrations was a delayed increase in the concentration of dopamine in hypophysial portal plasma and an increase in the turnover of dopamine in the median eminence. The morphine-induced stimulation of the release of dopamine into hypophyseal portal blood was attenuated significantly in animals treated with naltrexone (1 mg/kg). It is concluded that morphine exerts a biphasic effect on both the secretion of PRL and the release of dopamine from tuberoinfundibular neurons.(ABSTRACT TRUNCATED AT 250 WORDS) 相似文献

The purpose of this study has been to compare the acute antihypertensive effect of a dose of 20 mg of ketanserin in 18 patients after sublingual administration and in 19 after oral administration. In three patients ketanserin and ketanserin-ol plasma levels were measured after both sublingual and oral administration. The results showed a more rapid, considerable antihypertensive effect after sublingual administration. In addition, the high plasma levels of ketanserin-ol, the metabolite produced by hepatic reduction of ketanserin, reached after sublingual administration, rather than transmucosal absorption, indicate that the clinical effect observed is due to more rapid dissolution of the tablet formulation and liberation of the active drug. 相似文献
