Is Achieving High Flexion Necessary for Satisfaction after Total Knee Arthroplasty in Indian Patients?

Background: Total knee arthroplasty (TKA) is a very successful operation for the treatment of end-stage arthritis of the knee joint. In spite of improvement in surgical technique, implant design, postoperative pain management, and rehabilitation, some patients are not satisfied with the outcome of the surgery. It is believed that high-flexion (H-F) activities such as cross-legged sitting and squatting are necessary for satisfaction after TKA in Indian patients due to cultural and social reasons.

Estimation of carvedilol in human plasma by using HPLC-fluorescence detector and its application to pharmacokinetic study.

A simple, precise and sensitive high performance liquid chromatography procedure has been developed for determination of carvedilol in human plasma. The method was developed on Lichrosphere R CN column using a mobile phase of acetonitrile/20 mM ammonium acetate buffer with 0.1% triethylamine (pH adjusted to 4.

Routine chemoprophylaxis for deep venous thrombosis in Indian patients: Is it really justified?

Background: Venous thromboembolism (VTE), which consists of deep vein thrombosis (DVT) and pulmonary embolism, is a potentially fatal disease. According to the Western literature, DVT of lower limb veins is one of the most common complications following total hip and knee arthroplasty and surgeries for lower limb fractures. Very few studies have been published from India on the subject and very little is known about the true incidence of the condition.

A new high performance liquid chromatographic method for quantification of atomoxetine in human plasma and its application for pharmacokinetic study.

Atomoxetine is the first, non-stimulant alternative to other stimulant medications used for the treatment of Attention-Deficit/Hyperactivity Disorder (ADHD). Reported methods for the determination of atomoxetine include expensive liquid chromatography tandem mass spectrometry (LCMS) and high performance liquid chromatography (HPLC) with liquid scintillation counting (LSC) detection. Till date, no method has been reported in literature to determine atomoxetine using HPLC with UV detection.

Analytical method development and validation of mianserin hydrochloride and its metabolite in human plasma by LC-MS.

Mianserin is a tetracyclic antidepressant drug and administered as racemate of R (-) and S (+) mianserin hydrochloride in a dose of 30-90 mg/day in divided doses. Liquid chromatography-mass spectroscopy (LC-MS) is a tool, which is widely used for determination of drug and their metabolites in biological fluids because of its high sensitivity and precision. Here we describe a liquid chromatography mass spectroscopy method for simultaneous determination of mianserin and its metabolite, N-desmethylmianserin, from human plasma using a liquid-liquid extraction with hexane:isoamylalcohol (98:2) and back extraction with 0.

QSAR studies on some thiophene analogs as anti-inflammatory agents: enhancement of activity by electronic parameters and its utilization for chemical lead optimization.

Small molecule heterocycle is an integral part of new drug discovery in anti-inflammatory research. In our previous papers we reported the synthesis of thiophene analogs substituted at the fifth position with alpha-oximino propionic ester moiety and the fact that such new chemical entities exhibit anti-inflammatory activity in male/female Sprague-Dawley rats. In this paper we report the quantitative structure activity relationship (QSAR) studies of a series of 43 thiophene analogs.

Comparative study of plateletpheresis using Baxter CS 3000 plus and Haemonetics MCS 3P.

Platelet concentrates made from cell separators are used more frequently due to less donor exposure and leucodepletion. This retrospective study was done to compare plateletpheresis done on two cell separators: Baxter CS 3000 plus and Haemonetics MCS 3p. Plateletpheresis procedures, done from January 1997 to April 2002, were included in the study.

Safety and antiretroviral effectiveness of concomitant use of rifampicin and efavirenz for antiretroviral-naive patients in India who are coinfected with tuberculosis and HIV-1.

Objective: To study the safety and antiretroviral effectiveness of concomitant use of rifampicin and efavirenz for antiretroviral-naïve patients in India who are coinfected with tuberculosis (TB) and HIV-1.

Design And Methods: The study was an observational longitudinal cohort investigation. HIV-1-infected patients with CD4 cell counts of < or = 200/microL who attended the Infectious Disease Clinic of Sterling Hospital (Ahmedabad, India) from June 2001 to December 2002 were recruited for the study.
