We present a unique prospective study to estimate the median sustained stage-related improvement in pain and hand function in patients with trapezio-metacarpal joint osteoarthritis after administration of a single corticosteroid injection. Response to the corticosteroid injection was assessed using Disability of Arm Shoulder and Hand (DASH) and Visual Analogue Scale (VAS) pain scores. Self assessment scores revealed a reduction in pain and improvement in hand function. All patients reported a significant improvement in pain and hand function (p ≤ 0.05), regardless of the disease stage. Additionally, we observed a marked difference in the duration of improvement in hand function between early and late stages of the disease (p = 0.0046). In conclusion, it is possible to predict the period of symptomatic improvement at each of the four radiological stages of the disease. This would allow the treating clinician to judge the outcome of treatment with reasonable accuracy.
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.
Conventional energy resources are depleting very fast and to meet the global energy demand, the scarcity of these resources is the most crucial factor in the present era. One of the major contributors to carbon emissions is transportation sector which survives mostly on conventional energy resources. In the Indian context, the transportation sector contributes about 18% of CO 2 emissions of total emissions. To decarbonize this sector, the vehicles utilizing renewable resources such as solar PV technology would be a sustainable step. Solar energy which is abundant in nature and present everywhere can prove to be a great alternative to conventional resources. In the present study, solar PV technology is integrated with electric and hybrid vehicles. Additional literature review of solar electric vehicles including three-wheeled as well as four-wheeled is carried out. Autonomous vehicles and robots utilizing PV technology are also studied and presented. Finally, the foremost barriers and challenges to adopting PV technology in electric and autonomous vehicles are identified and presented.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
