Haemostasis in Open Carpal Tunnel Release: Tourniquet vs Local Anaesthetic and Adrenaline

Open carpal tunnel release is one of the commonest performed procedures in hand surgery. We performed a prospective randomised control trial to compare the efficacy and patient satisfaction of the traditional arm tourniquet versus infiltration of adrenaline and local anaesthetic solution to achieve haemostasis during the procedure. Using a combination of objective and subjective measures we concluded that infiltration of local anaesthetic and adrenaline not only provided adequate haemostasis but also provided a significantly more tolerable experience for the patient during the procedure

SARS-CoV-2 B.1.617.2 Delta variant replication and immune evasion

The B.1.617.2 (Delta) variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was first identified in the state of Maharashtra in late 2020 and spread throughout India, outcompeting pre-existing lineages including B.1.617.1 (Kappa) and B.1.1.7 (Alpha)1. In vitro, B.1.617.2 is sixfold less sensitive to serum neutralizing antibodies from recovered individuals, and eightfold less sensitive to vaccine-elicited antibodies, compared with wild-type Wuhan-1 bearing D614G. Serum neutralizing titres against B.1.617.2 were lower in ChAdOx1 vaccinees than in BNT162b2 vaccinees. B.1.617.2 spike pseudotyped viruses exhibited compromised sensitivity to monoclonal antibodies to the receptor-binding domain and the amino-terminal domain. B.1.617.2 demonstrated higher replication efficiency than B.1.1.7 in both airway organoid and human airway epithelial systems, associated with B.1.617.2 spike being in a predominantly cleaved state compared with B.1.1.7 spike. The B.1.617.2 spike protein was able to mediate highly efficient syncytium formation that was less sensitive to inhibition by neutralizing antibody, compared with that of wild-type spike. We also observed that B.1.617.2 had higher replication and spike-mediated entry than B.1.617.1, potentially explaining the B.1.617.2 dominance. In an analysis of more than 130 SARS-CoV-2-infected health care workers across three centres in India during a period of mixed lineage circulation, we observed reduced ChAdOx1 vaccine effectiveness against B.1.617.2 relative to non-B.1.617.2, with the caveat of possible residual confounding. Compromised vaccine efficacy against the highly fit and immune-evasive B.1.617.2 Delta variant warrants continued infection control measures in the post-vaccination era

Project Tracking and Management System

Project Tracking and Management System is a software package to monitor the progress and status of projects undertaken by an organization. The package provides information on projects which include Management (Customer and General), Financial and Technical details. It also facilitates generation of textual and graphical reports as well. It is an intranet application that can be accessed from any desktop system

In situ transmission electron microscopy study of deformation of an aluminum alloy tribolayer

Nanoscale deformation in the tribolayer of an Al–Mg alloy is studied using an in situ mechanical probe in a transmission electron microscope. The sample is strained locally at room temperature and the deformation is observed in real time. It is observed that when the tungsten probe comes into contact with the tribolayer, the material exhibits further hardening followed by material removal

Biodentine and Amniotic Membrane to Treat the Hidden Villain- A Rare Case of Labiocervical Vertical Groove

This case report signifies the importance of complications and early diagnosis of radicular groove and to discuss the treatment of combined endo-perio lesion using bone graft mixed with Platelet Rich Fibrin (PRF), amniotic membrane and biodentine. Labiocervical Vertical Groove (LCVG) presents various complications to the patients, especially if it extends to the pulpal space. Labiocervical vertical groove originating near the cervical area of tooth can extend to the radicular surface. These grooves can be mild, moderate or deep based on its extent and depth. This case report deals with the complications, degree of destruction and treatment of an intrabony defect associated with LCVG in maxillary central incisor in a 35-year-old male patient, who reported to the Department of Periodontics and Implantology with the chief complaint of mobility of teeth over a period of past two months. In this case report, authors have highlighted the advantages of saucerisation, PRF, amniotic membrane and biodentine to treat the bone loss along with restoration of the groove
