Flat foot in children is a common deformation, which appears during the first years of life. It requires a rigorous evaluation to rule out congenital or neurological abnormality. It is characterized by a decrease of the plantar concavity indeed collapse of the foot, often associated with other morphostatic deformations. The aim of this study is to find a correlation between the essential flat foot in children and lower limb disorders torsional. It is a cross-sectional descriptive study, recruiting 110 children (220 feet) aged between 3 and 6 years old. Each child was given an assessment of the morphology of the foot (Contact Index II…) and lower limb rotational profile (intoeing and femoral antétorsion and tibal torsion). Among 110 children, 21 (19.1%) have bilateral flat feet and 7 (6.4%) have unilateral flat feet, associated with an average value of Contact Index II equal to 0.921;the minimum value is 0.880 and the maximum value is 1.17. All children with flat feet have excessive femoral antétorsion;45 (92%) are associated with a hip intoeing and 38 (80%) present an insufficient external tibial torsion. The analysis of multiple regression shows a significantly elevated correlation among the flat foot and excessive internal rotation of the hip (F = 70.36, r = 0.77, P < 0.001), excessive femoral antetorsion (F = 54.78, r = 0.73, P < 0.001) and insufficient external tibial torsion (F = 7.79, r = 0.37, P < 0.001).

Improvements in imaging technology allow exploitation of the dual blood supply of the liver to aid in the identif ication and characterisation of both malignant and benign liver lesions. Imaging techniques available include contrast enhanced ultrasound, computed tomography and magnetic resonance imaging. This review discusses the application of several imaging techniques in the diagnosis and staging of both hepatocellular carcinoma and cholangiocarcinoma and outlines certain characteristics of benign liver lesions. The advantages of each imaging technique are highlighted, while underscoring the potential pitfalls and limitations of each imaging modality.

Objective: The present study aimed to quantify and identify the bioactive compounds of the Arbutus unedo L. leaves in order to evaluate both their antioxidant properties and litholytic activities against calcium oxalate ***: This survey was carried out using hydroalcoholic extract(***) and infusion(***) of A. unedo leaves. The quantification of phenolic compounds, flavonoids, flavonols and anthocyanins was done by spectrophotometric methods and identification of chemical components was performed by ultraperformance liquid chromatography with photodiode array and electrospray ionization tandem mass spectrometry. Antioxidant activity was measured using the 1,1-diphenyl-2-picrylhydrazyl(DPPH)method and by the ferric reducing/antioxidant power(FRAP) assay. Litholytic activity of *** and *** was studied using a special model that resembles circuitry of the urinary ***: *** showed greater antioxidant efficacy than ***(P < 0.05). Its higher efficiency was shown via the values of median inhibitory concentration, which was close to(76.14 ± 0.91) mg/mL for *** versus(202.64 ± 5.77) lg/mL for *** using the DPPH method, and(53.77 ± 0.81) lg/mL for *** versus(236.86 ± 31.90) lg/mL for ***, using FRAP method. *** exhibited significantly higher litholytic activity compared to ***(P < 0.05), with dissolution values of 31.03% ± 0.63% versus 14.55% ± 0.65%, ***: Overall, the results suggest that the A. unedo is rich in bioactive compounds, and possesses antioxidant and litholitic abilities that are worthy of further study.

Tako-tsubo cardiomyopathy in a male patient after administration of isoproterenol and implantation of a pacemaker

引用

World Journal of Cardiovascular Diseases 2012年第1期2卷 38-41页

Background: Tako-tsubo cardiomyopathy occurs typicallly after an intrinsic adrenergic hyperstimulation triggered by a psychological or physically stressful event. Exceptionally, it may be caused by an exogenous hyperadrenergism. We report the case of an 85 year old man, hypertensive, with a history of ischemic stroke. He consulted for signs of heart failure with recurrent dizziness two weeks which was explained by an atrioventricular block. Initial echocardiography showed left ventricular ejection fraction to 60% with no wall motion abnormalities. The patient received iso-prenaline (0.02 mcg/kg/mn) for 20 hours before the implantation of a single chamber pacemaker. At 24 hours of admission an acute pulmonary edema occurred. The control echocardiography showed impaired left ventricular ejection fraction of 25% with apical ballooning and akinesis was also found on ventricu-lography. Coronary angiography showed no significant coronary lesions. Troponin level was elevated to 2 ng/ml. The pulmonary edema was then controlled. Subsequent clinical and echocardiographic were favo- rable after two weeks which was consistent with the diagnosis of tako-tsubo cardiomyopathy. Conclusion: This case illustrates an example of tako-tsubo syndrome induced by an exogenous catecholergic stimulation (isoprenaline) combined with an endogenous release after a pacemaker implantation which confirmed the physiopathological hypothesis of a catecholamine-mediated stunning in tako-tsubo cardiomyopathy.

Cost Effectiveness Analysis of Filgrastim versus Placebo in Post AIIogentic Bone Marrow Transplantation

Filgrastim is used to accelerate hematopoietic recovery after ABMT （allogeneic bone marrow transplantation）. Its impact on the total cost of patient care remains to be explored. We therefore undertook a cost effectiveness analysis in the context of a randomized single blinded clinical trial of Filgrastim versus placebo in post ABMT. A primary endpoint, duration of myelosuppression, and three secondary end points （number of days of fever, length of hospital stay, survival at one hundred days） were used to assess efficacy. Direct costs were evaluated and allowed the calculation of the ICER （incremental cost-effectiveness ratios） for the major endpoint of the trial. Sixteen patients were included in the study. The duration of myelosuppression was significantly decreased in the Filgrastim arm with medians of 15 days vs. 19 days in the placebo arm （p = 0.023）. Cost analysis showed no statistically significant difference between the two arms. According to the calculation of ICER, Filgrastim was more costly and more effective than placebo for the number of days of aplasia avoided and the number of days with fever avoided. Placebo strictly dominated filgrastim for days of hospitalization avoided. Filgrastim has proven effective in reducing the duration of aplasia without increasing costs.

Effects of Drying on the Biochemical Composition of <i>Atherina boyeri</i>from the Tunisian Coast

引用

Food and Nutrition Sciences 2014年第14期5卷 1399-1407页

作者： mohamed Ali ben Smida Alěs Bolje Anissa Ouerhani Manel Barhoumi Hassen Mejri M’hamed El Cafsi Rafika Fehri-Bedoui Faculté des Sciences de Tunis Université de Tunis El Manar Tunis Tunisie Fisheries Research Institute of Slovenia Ljubljana Slovenia

The effects of solar and experimental drying on the protein concentration and total fatty acid (TFA) content of the muscles of Atherina boyeri (sand smelt) were studied. The percentage of protein was 18.3% for fresh fish and 14.2% for sun-dried fish, while TFA content was 4.9 g/100g and 0.5 g/100g. After the drying experiment, the percentage of protein was 23% and the fatty acid (FA) content was 2.8 g/100g. The results show that natural or experimental drying favors saturated fatty acids. The n-3 polyunsaturated fatty acids (PUFAs) are less sensitive to heat than the n-6 PUFAs. From a nutritional point of view, it seems that the drying conditions, where parameters are T = 50℃, moisture = 30% and air speed = 2 m/s, would be the most beneficial for the preservation of sand smelt.
