Objective: To evaluate the effectiveness of Judet''s quadricepsplasty for treatment of knee contractures and to identify the effect of local infiltration of epinephrine on blood loss associated with this procedure.
Methods: A retrospective cohort study was conducted in which all cases of knee contractures managed
with Judet''s quadricepsplasty from 1st January 2009 to 31st December 2013 were included and were
divided into two groups. The epinephrine group included patients who were infiltrated with diluted
epinephrine (1:400,000) along with xylocaine, around the operative field 15 min prior to the incision
time, while the control group did not receive any infiltration. Judet''s outcome, blood loss, drop in hemoglobin and required blood transfusion were noted for all patients and compared between both groups.
Results: Most common preceding pathology identified for the development of knee contractures was
periarticular fracture while ilizarov application was the most common etiology. Both groups were found similar in all preoperative characteristics except preoperative flexion contracture (p=0.02). All functional outcome measures including Judet''s outcome were similar in both groups. In contrast, duration of surgery (p=0.01), blood loss (p=0.02), drop in hemoglobin (p=0.01) and number of transfusions (p=0.03) were significantly reduced in epinephrine group.
Conclusion: Judet''s quadricepsplasty is a useful procedure to increase the range of motion of rigid knees and local infiltration of epinephrine is effective in decreasing the amount of subsequent blood loss and transfusion requirements. 相似文献

Accurate determination of left ventricular mass, volume, ejection fraction, and wall motion is important for clinical decision making. Currently, M-mode and two-dimensional echocardiography (2DE) have been routinely used for this purpose. Although these 1D or 2D modalities provide excellent diagnostic and prognostic information, they have a number of technical limitations including the time required to perform the procedure and operator-dependent image acquisitions. In addition, they are inherently limited by geometric assumption of three-dimensional (3D) left ventricular structures based on 2D slices. With the improvement in transducer technology and software development, 3D echocardiography (3DE) has become widely available. Left ventricular quantitation by 3DE has been demonstrated to be accurate by multiple studies that compared 3DE with reference techniques. In addition, 3DE measurements were found to be more reproducible and less variable than 2DE. Real time 3DE imaging has potential advantages in stress echocardiography including rapid acquisition, unlimited number of planes, avoidance of foreshortening, and precise segment matching. This is a major step forward in our diagnostic armamentarium for the evaluation of ischemia. In this review, we summarized the current evidence of 3DE for left ventricular evaluation.

This study reports on infective endarteritis in 14 children with patent ductus arteriosus over a period of 6 years. Infective endarteritis mostly involved the small ducts and was previously undiagnosed. These patients were given antibiotic treatment for a variable period of 4 to 10 weeks, and all except 1 underwent subsequent closure. 相似文献

Background: Low incidence of reversal blood flow at the portal vein has been reported by measurement in larger and extrahepatic blood vessels but not in intrahepatic blood vessels in patients with liver cirrhosis. Moreover, there is little information regarding the incidence of reversal blood on the basis of the cause of liver cirrhosis. The aim of this study was to measure the reversal blood flow in the portal vein including intrahepatic branches in patients with alcoholic and viral cirrhosis.
Methods: The blood flow in the portal vein and existence of portosystemic shunt were studied in 52 and 27 patients with alcoholic and viral cirrhosis, respectively, by Doppler ultrasonography. The parameters of liver function test and the prevalence of ascites and esophageal varices were compared between patients with and without reversal blood flow.
Results: Reversal blood flow at the portal vein was found only in patients with only alcoholic cirrhosis (17 of 52 patients) but not in any patients with viral cirrhosis (0 of 27 patients; p < 0.05). The incidence of portosystemic ascites and red color of esophageal varices was also higher in patients with alcoholic cirrhosis with reversal blood flow in the portal vein compared with patients without reversal blood flow ( p < 0.05).
Conclusions: Reversal blood flow in the portal vein is a characteristic feature of alcoholic cirrhosis. The presence of reversal blood flow indicates severe liver diseases, and this feature may have prognostic importance for patients with alcoholic cirrhosis. 相似文献

Background
Diabetes mellitus is characterized jointly by hyperglycemia and hyperinsulinemia that make insulin more prone to be glycated and evolve insulin advanced glycation end products (Insulin- AGE). Here, we report the effect of beta-hydroxy butyrate (BHB) (the predominant ketone body) on the formation of insulin-AGE, insulin glycation derived liposomal lipid peroxidation and insulin-AGE toxicity in microglial cells.Methods
The inhibitory effect of BHB was monitored as a result of insulin incubation in the presence of glucose or fructose using AGE-dependent fluorescence, Tyr fluorescence as well as anilinonaphthalenesulfonate (ANS) andthioflavin T (ThT) binding, and circular dichroism (CD) investigations. To study lipid peroxidation induced by insulin glycation, thiobarbituric acid (TBA) assay and thiobarbituric acid reactive substance (TBARS) monitoring were used. The effect of insulin–AGE on microglial viability was investigated by 3-(4, 5 dimethylthiazol-2-yl)—2, 5-diphenyltetrazoliumbromide (MTT) cell assay and Annexin V/propidium iodide (PI) staining.Results
Here we are reporting the inhibitory effect of BHB on insulin glycation and generation of insulin-AGE as a possible explanation for insulin resistance. Moreover, the protective effect of BHB on consequential glycation derived liposomal lipid peroxidation as a causative event in microglial apoptosis is reported.Conclusion
The reduced insulin fibril formation, structural inertia to glycation involved conformational changes, anti-lipid peroxidation effect, and increasing microglia viability indicated the protective effect of BHB that disclose insight on the possible preventive effect of BHB on Alzheimer’s disease. 相似文献46.

The combination of visible-light and tris(trimethylsilyl)silane promoting intramolecular reductive cyclization protocol for the synthesis of functionalized indolines and 2,3-dihydrobenzofurans has been developed. The transformations occur in the absence of transition metal and additional photocatalyst. In addition, quantum yield (Φ) was determined and electron paramagnetic resonance spectroscopy was performed to better understand the reaction pathway.The combination of visible-light and tris(trimethylsilyl)silane promoting intramolecular reductive cyclization protocol for the synthesis of functionalized indolines and 2,3-dihydrobenzofurans has been developed. 相似文献

Background: Baseline clinical and physiological variables have been described as relevant predictors of survival among patients with idiopathic pulmonary fibrosis (IPF). However, substantial heterogeneity in both survival time and mortality has been observed with many of these predictive factors. The incidence and mortality rates of IPF vary from country to country, with race potentially contributing to such variations. Objective: We sought to describe baseline clinical features to determine their predictive value among Middle Eastern patients diagnosed with IPF. Methods: We retrospectively examined 61 patients diagnosed with IPF at a university hospital in Riyadh, Saudi Arabia. Results: At presentation, most patients exhibited either dyspnea or cough. The median survival time for all patients was 92 months. Diminished survival was significantly associated with finger clubbing (P = 0.01). Factors not influencing survival were age, gender, percent predicted forced vital capacity, percent predicted forced expiratory volume in 1 s, percent predicted total lung capacity, percent predicted diffusion capacity of the lung for carbon monoxide and resting oxygen saturation. Conclusions: Finger clubbing is a significant predictive variable and was associated with a 5‐fold increase in mortality. Other baseline demographic characteristics as well as pulmonary function tests were not predictive of prognosis in Middle Eastern patients with IPF. It appears that IPF patients of Middle Eastern descent have a longer median survival curve compared to other races. Please cite this paper as: Alhamad EH, Masood M, Shaik SA and Arafah M.
