Identification of factors contributing to the development of postoperative delirium in geriatric patients with hip fractures- A prospective study.

Introduction: Geriatric hip fractures are a major cause of concern globally and often a frequent reason for morbidity and mortality. Postoperative delirium (POD) is a frequent but often under-diagnosed complication, especially after a major hip surgery. Some of the factors that have been associated with POD are diabetes, high American Society of Anesthesiologists (ASA) grading, electrolyte imbalance, and blood pressure fluctuations.

Bone tumors in a tertiary care hospital of south India: A review 117 cases.

Background: Bone tumors remain a daunting challenge to orthopedic surgeons. The challenge is heightened in developing countries due to limited diagnostic and therapeutic facilities as well as due to ignorance. The published literature on this subject is sparse in our environment.

Complexometric determination of mercury(II) by use of 4-amino-5-mercapto-3-propyl-1,2,4-triazole as replacing reagent.

A simple, rapid, and selective complexometric method is proposed for the determination of mercury(II). Mercury(II) is first complexed with excess of EDTA and the surplus EDTA is back-titrated (pH 5-6) with zinc sulphate solution, with Xylenol Orange as indicator. 4-Amino-5-mercapto-3-propyl-1,2,4-triazole is then added to displace EDTA from the Hg-EDTA complex and the released EDTA is titrated with zinc sulphate solution.
