An innovative 'Prop technique' of mouth opening in post-COVID-19 mucormycosis maxillectomy: Finding a new way with minimal efforts.

General anaesthesia is associated with damage to teeth, particularly during laryngoscopy. Dental injury is more probable when pre-existing dental pathology or risk factors are present. Post-coronavirus disease -2019 mucormycosis is a rare, fulminant, lethal, angio-invasive, opportunistic fungal disease and is increasingly recognised in diabetic and immunocompromised patients.

A four-component modified Biginelli reaction: A novel approach for C-2 functionalized dihydropyrimidines.

A novel four component modified Biginelli reaction for the synthesis of C-2 functionalized dihydropyrimidines has been established. The approach uses assembly of less explored acetyl acetone with aromatic aldehyde, thiourea, and dimethyl sulphate to construct a novel 5-acetyl 2-methylthio dihydropyrimidine system, which works as an efficient well-designed intermediate for generating C-2 modified Biginelli libraries with nitrogen nucleophiles. Phenyl hydrazine, semicarbazide, and aryl semicarbazides are successfully used as N-nucleophiles to generate C-2 functionalized dihydropyrimidine derivatives, which fulfil the demands of active pharmacophore.

A cohort study of anatomical landmark-guided midline versus pre-procedure ultrasound-guided midline technique of spinal anesthesia in elderly patients undergoing orthopedic surgery.

Background And Aims: The primary objective of the study was to compare the number of attempts and number of passes of spinal needle insertion and secondary objective was to compare complications, bloody tap, and patient discomfort in anatomical landmark-guided versus pre-procedure USG-guided midline technique of spinal anesthesia in elderly patients posted for orthopedic surgery.

Material And Methods: In this a prospective observational cohort study, 60 patients of either sex, ASA grades I-III, and aged more than 65 years were randomly allocated to 2 groups of 30 patients each. In group AG (Anatomical landmark guided), standard landmark technique was used.

A prospective observational study of predictors of difficult intubation in Indian patients.

Background And Aims: During routine preoperative assessment of patients one of the commonest practices is predicting difficulty of intubation. The present study was undertaken to evaluate parameters associated with difficult intubation and to test on new set of patients. At the end, to form simple predictive rule to decreased the number of false alarms.

Design, synthesis and biological evaluation of novel thiosemicarbazide analogues as potent anticonvulsant agents.

Novel thiosemicarbazide derivatives were synthesised and evaluated for their anticonvulsant activity and neurotoxicity. Anticonvulsant activity was done for grand mal and petit mal types of epilepsies by maximal electroshock (MES) and pentylenetetrazol (PTZ) induced convulsions methods respectively. Rotarod test was done to determine neurotoxicity.
