Primary Retrograde Tibiotalocalcaneal Nailing in an Elderly Osteoporotic Patient With Ankle Fracture: A Case Report.

Introduction: Ankle fractures are a common orthopedic injury traditionally treated with open reduction and internal fixation or conservative management. One complication introduced with open reduction and internal fixation is the requirement for non or partial weight bearing in the post-operative period. This requirement poses a unique challenge for patients who may not comply with these weight-bearing restrictions.

In vitro and in vivo assessment of newer quinoxaline-oxadiazole hybrids as antimicrobial and antiprotozoal agents.

A new series of N-(substituted-phenyl)-2-[5-(quinoxalin-2-yloxymethyl)-[1,3,4] oxadiazol-2-ylsulfanyl]-acetamides (5a-o) was designed and synthesised from the parent compound 2-hydroxy quinoxaline (1) through a multistep reaction sequence and was characterised by spectral and elemental analyses. All of the compounds synthesised were evaluated for their antimicrobial and antiprotozoal activities. The results revealed that quinoxaline-based 1,3,4-oxadiazoles displayed promising antibacterial, antifungal and anti-Trypanosoma cruzi activities compared with reference drugs, particularly the lead compound 5l in a short-term in vivo model in T.

Sulfonamides of 2-[(2,6-dichlorophenyl)amino]phenyl acetoxyacetic acid and their antibacterial studies.

Abstract: Reaction of 2-[(2,6-dichlorophenyl)amino]phenylacetoxyacetyl chloride 2 with various N'-(substituted aryl)-p-aminobenzenesulfonamide derivatives afforded title compounds. All the final compounds were characterized by the IR spectral data and elemental analysis and screened for antibacterial activity against Gram positive and Gram negativebacterial strains.
