Liposuction is one of the most frequently performed cosmetic surgeries worldwide for reshaping the body contour. Although liposuction is minimally invasive and relatively safe, it is a surgical procedure, and it carries the risk of major and minor complications. These complications vary from postoperative nausea to life-threatening events. Common complications include infection, abdominal wall injury, bowel herniation, bleeding, haematoma, seroma, and lymphoedema. Life-threatening complications such as necrotizing fasciitis, deep vein thrombosis, and pulmonary embolism have also been reported. In this paper, we provide a brief introduction to liposuction with the related anatomy and present computed tomography and ultrasonography findings of a wide spectrum of postoperative complications associated with liposuction. 相似文献

Background:Many pediatric forearm fractures can be treated in plaster following closed reduction. The cast index (CI, a ratio of anteroposterior to lateral internal diameters of the cast at the fracture site) is a simple, reliable marker of quality of molding and a CI of >0.8 correlates with increased risk of redisplacement. Previously, CI has been applied to all forearm fractures. We hypothesize that an acceptable CI is more difficult to achieve and does not predict outcome in fractures of the proximal forearm.Results:The mean CI was 0.77. Remanipulation was required in five cases (6%), all distal half fractures – mean CI 0.79. CI was higher in proximal half forearm fractures (0.83 vs. 0.76, P = 0.006), nonetheless these fractures did not re-displace more than distal fractures.Conclusion:Cast index is useful in predicting redisplacement of manipulated distal forearm fractures. We found that in proximal half forearm fractures it is difficult to achieve a CI of <0.8, but increased CI does not predict loss of position in these fractures. We therefore discourage the use of CI in proximal half forearm fractures. 相似文献

Eighteen children with cerebral palsy in a special school, most of whom had feeding difficulties, were studied to compare
the diagnostic value of the Exeter Dysphagia Assessment Technique (EDAT) with an exhaustive clinical assessment undertaken
by a multidisciplinary team experienced in the diagnosis and treatment of dysphagia of neurological origin. Four feeding skills
were assessed by each method independently, viz. anticipation, intraoral sensory perception, oral-motor efficiency, and pharyngeal
triggering. Comparison of the two sets of results showed agreement in at least 78% of the assessed skills. The possible reasons
for the few discrepancies are discussed. The noninvasive EDAT equipment was easy to use with the children, who had a range
of type and severity of cerebral palsy. The test was undertaken in their familiar surroundings and took 15 to 20 min per child.
Interpretation of the results showed that EDAT provided a rapid, reliable diagnostic aid which assisted in the assessment
of the degree of feeding impairment within each of the four feeding skills tested.

Objectives
This study investigated the prognostic value of first-phase ejection fraction (EF1) in patients with aortic stenosis (AS), a condition in which left ventricular dysfunction as measured by conventional indices is an indication for valve replacement.Background
EF1, the ejection fraction up to the time of maximal ventricular contraction may be more sensitive than existing markers in detecting early systolic dysfunction.Methods
The predictive value of EF1 compared to that of conventional echocardiographic indices for outcomes was assessed in 218 asymptomatic patients with at least moderate AS, including 73 with moderate, 50 with severe, and 96 with “discordant” (aortic area <1.0 cm2 and gradient <40 mm Hg) AS, all with preserved EF, followed for at least 2 years. EF1 was measured retrospectively from archived echocardiographic images by wall tracking of the endocardium. The primary outcome was a combination of aortic valve intervention, hospitalization for heart failure, and death from any cause.Results
EF1 was the most powerful predictor of events in the total population and all subgroups. A cutoff value of 25% (or EF1 of <25% compared to ≥25%) gave hazard ratios of 27.7 (95% confidence interval [CI]: 13.1 to 58.7; p < 0.001) unadjusted and 24.4 (95% CI: 11.3 to 52.7; p < 0.001) adjusted for other echocardiographic measurements including global longitudinal strain, for events at 2 years in all patients with asymptomatic AS. Corresponding hazard ratios for all-cause mortality in the total population were 17.5 (95% CI: 5.7 to 53.3) and 17.4 (95% CI: 5.5 to 55.2) unadjusted and adjusted, respectively.Conclusions
EF1 may be potentially valuable in the clinical management of patients with AS and other conditions in which there is progression from early to late systolic dysfunction. 相似文献58.

Summary In early myocardial ischemia we find a number of salient electrical and ionic alterations. This article reviews action potential shortening, K accumulation, and contractile failure. Enhanced K efflux during early myocardial ischemia has been attributed to a number of mechanisms, including: the inhibition of active K uptake, osmotic changes, efflux of K ions linked to anion extrusion, cation exchange, altered cellular energy levels, in particular, the opening of ATP-dependent K channels, the involvement of other ion channels, a H/K-ion exchanger, and a catecholamine-dependent pathway. The different mechanisms are discussed. Action potential shortening was described as a salient characteristic of myocardial ischemia in 1954 by Trautwein and Dudel, and was attributed to enhanced outward current. Recently it has been shown by several authors that ATP-dependent potassium channels play a key role in this context. Contractile failure in early myocardial ischemia has been explained by shortening of the action potential duration, reduced cytoplasmic free calcium levels, intracellular acidification, and a rise in inorganic phosphate and Mg. In summary, it is concluded that ATP-dependent K channels may be involved in each of these three phenomena. 相似文献
