| Sumario: | Introduction: Chemicals that are present in cigarette/bidi smoke
and gutka have been known to cause subclinical changes in
myelin sheaths of peripheral nerves. Despite the antiquity and
popularity of smoking and gutka chewing, its effect has not
been investigated systematically in young adults.
Aim: To investigate the chronic effects of smoking and gutka
chewing on Nerve Conduction Velocity (NCV).
Materials and Methods: The case-control study was conducted
in the Department of Physiology, Jawaharlal Nehru Medical College,
Aligarh Muslim University, Aligarh, Uttar Pradesh, India, from
November 2018 to December 2020. A 40 male smokers (age
group 20-60 years), 40 gutka chewers (age group 20-60 years)
along with 40 age matched healthy male controls. The nerve
conduction study was performed by using fully computerised
Electromyography (EMG) and NCV machine. Sensory Nerve
Conduction Velocity (SNCV) and Motor Nerve Conduction
Velocity (MNCV) test of median and ulnar nerves was performed
on subjects. Data was analysed by using unpaired t-test.
Results: In this study of comparative analysis of total 120 subjects,
[40 controls and 80 cases (40 cases of smokers and tobacco
chewers each)], statistically significant changes (p-value <0.05)
were found in the sensory NCV of both the nerves and motor NCV
of median nerve in smokers whereas no such changes were found
in motor NCV of both nerves in gutka chewers.
Conclusion: It can be concluded that smoking causes more
reduction in NCV than gutka chewing. |
