Functional analysis of cemented bipolar hemiarthroplasty with medial calcar augmentation for unstable intertrochanteric fractures in elderly

Background: Intertrochanteric fracture is one of the most common fractures among the elderly osteoporotic population, constituting about 50% of hip fractures. These fractures are managed either by fixation using dynamic hip screw (DHS), proximal femur nail (PFN) or by replacement, based on the stability of fracture pattern, age of the patient, quality of bone and associated co-morbid conditions. Prosthetic replacement which is routinely done for femoral neck fractures requires modification when done for trochanteric fractures to improve stability. This study aims to analyse the short term functional outcome of cemented bipolar hemiarthroplasty with medial calcar augmentation for unstable intertrochanteric fractures in elderly.Methods: Our study includes 60 patients of age more than 70 years admitted in our institution during June 2012 to September 2016 with unstable intertrochanteric fractures. All patients operated through posterior approach to hip and cemented hemiarthroplasty with medial calcar augmentation with bone graft was done. Patients were followed up for an average of period of 2 years. Functional outcome was evaluated with Harris Hip score.Results: 28% of cases had excellent outcome. 43% of cases had good and 23% of cases had fair outcome. 2% of cases ended with poor outcome. The in-hospital mortality rate was 3.3%. The survival rate of the patients in this study at the end of one year is 85%. Conclusions: Cemented bipolar hemiarthroplasty with medial calcar augumentation can be considered as a good primary option for elderly unstable intertrochanteric fracture patients with osteoporotic bones and associated co-morbidities. 

Synthesis, spectral, antibacterial and docking analyses of (3,4-bis((E)-(arylidene)amino)phenyl)(phenyl)methanones

Biologically active Schiff bases namely (3,4-bis((E)-(arylidene)amino) phenyl)(phenyl)methanones have been synthesized through ultrasonicated condensation of (3,4-diaminophenyl)(phenyl)methanone and various benzaldehydes in ethanol medium. Synthesised Schiff bases have been examined by different techniques like molecular formula calculation, molecular weight determination, melting point determination, micro analysis and spectroscopic data. The in vitro antibacterial actions of these E-imines have been assessed against bacterial strains by zone inhibition and serial dilution methods. Further, molecular docking analysis of all E-imines have been accomplished to comprehend the order of binding of Schiff bases with protein

Ultrasonicated synthesis of some potent antimicrobial aryl sulphonamides

1373-1377Nine N-(2,4-difluorophenyl) substituted benzene sulphonamides have been synthesized by ultrasonication method within short reaction time having more than 90% yield. These sulphonamides have been analyzed by spectral and analytical techniques. The higher yields of sulphonamides have been found to be in case of ultrasonication process as compared to microwave and conventional heating methods. The antimicrobial activities of these sulphonamides have been evaluated using Bauer-Kirby disc diffusion method by means of measurement of mm of zone of inhibition

Student Satisfaction and Performance in an Online Teacher Certification Program

The article presents a study which demonstrates the effectiveness of an online post baccalaureate teacher certification program developed by a Wisconsin university. The case method approach employing multiple methods and multiple data sources were used to investigate the degree to which pre-service teachers were prepared to teach. It was concluded that the study supports online delivery as an effective means of teacher preparation, but it was limited in the number of students followed into their first year of teaching

Development and validation of reversed phase gradient HPLC method for the simultaneous estimation of olmesartan medoxomil and chlorthalidone in dosage forms

ABSTRACT The main objective of the proposed study is to develop and validate a new stability indicating reverse phase HPLC gradient method for the simultaneous estimation of olmesartan medoxomil and chlorthalidone in combined dosage form. The method is optimized by using zorbax phenyl column (250 x 4.6 mm, 5 μ). For pump-A, ammonium dihydrogen orthophosphate and pump-B, acetonitrile: are used. Phosphate buffer pH was adjusted with orthophosphoric acid to 3.0. Water and acetonitrile (45:50) are used as diluent. The flow rate is 1.5 ml/min and the elutant is monitored at 220 nm with uv detector. The retention time of olmesatran medoxomil and chlorthalidone are 10.70 ±0.1 mins and 4.8 ± 0.1 mins respectively. Precision shows that % Relative standard deviation of olmesartan medoxomil and chlorthalidone is about 0.23 and 0.56 respectively. The percentage recoveries of both the drugs olmesartan medoxomil and chlorthalidone from the dosage formulation are 100.3% and 99.20% respectively. Linearity of olmesartan medoxomil and chlorthalidone is in the range of 10.0 to 60.0 μg/ml and 6.25 μg/ml respectively. Calibration curve shows good linearity and range. The correlation coefficient of olmesartan medoxomil and chlorthalidone is 0.999. And the results obtained for Robustness and Ruggedness are well within the acceptance criteria. The proposed method is found to be simple, rapid, accurate and precise. It is found to be economical and suitable for simultaneous determination of olmesartan medoxomil and chlorthalidone in pharmaceutical dosage form. World Scientific News 9 (2015) 132-154 -133
