Clinical Outcome for Lumbar Disc Herniation Treatment with Intradiscal Oxygen-ozone Therapy.

Background: Low back pain due to disc herniation is a common problem causing frequent hospital visits and loss of working days with major socio-economic impact. Conservative treatments like analgesics, physiotherapy do not work in all patients. Surgical treatment has been the mainstay of treatment when indicated but is associated with anesthetic and surgical complications.

Sympathetic Blocks for Raynaud's Phenomena in Pediatric Rheumatological Disorders.

Objective: Sympathetic blocks are invaluable to prevent morbidity from Raynaud's phenomenon (RP). RP may occur in children with rheumatological disorders and causes severe pain, discoloration of digits, gangrene, and auto-amputation. We describe the planning and execution of sympathectomy blocks in children with rheumatological disorders presenting with RP.

A novel synthesis of 2-arylbenzimidazoles in molecular sieves-MeOH system and their antitubercular activity.

Arylbenzimidazoles have been synthesized as antimycobacterial agents. An efficient synthesis has been developed for 2-arylbenzimidazoles from o-phenylenediamines and aromatic aldehydes in molecular sieves-methanol system. The methodology is straightforward to get 2-arylbenzimidazoles (3a-3z) in excellent yields with high chemoselectivity over 2-aryl-1-benzylbenzimidazoles (4a-4z).

Syntheses of lipophilic chalcones and their conformationally restricted analogues as antitubercular agents.

Lipophilic chalcones and their conformationally restricted analogues were synthesized and evaluated for their antitubercular efficacy against Mycobacterium tuberculosis H37Rv strain. Compounds 16, 24, 25a and 25c were found to be active MIC at 60, 30, 3.5 and 7.

1-Chloro-2-formyl indenes and tetralenes as antitubercular agents.

1-Chloro-2-formyl indenes and tetralenes have been synthesized using Vilsmeier-Haack-Arnold reaction onto indanones and tetralones. Most of these analogues exhibited antitubercular activity against Mycobacterium tuberculosis H37Rv strain with MICs ranging from 30 to 500 μg/mL. Analogue 13 was further modified to some derivatives.

A bioactive labdane diterpenoid from Curcuma amada and its semisynthetic analogues as antitubercular agents.

A labdane diterpene dialdehyde was first time isolated from the chloroform extract of rhizomes of Curcuma amada. This compound exhibited antitubercular activity (MIC=500 microg/mL) against Mycobacterium tuberculosis H(37)Rv strain in BACTEC-460 assay. Two of its semisynthetic analogues also exhibited antitubercular activity at 250-500 microg/mL.
