Are we still seeing Buerger's disease (TAO)?

we used to see more patients with gangrenous tips due to excessive smoking in young people 15 years back. Then slowly the number of such patients attending our clinic slowly decreased. But in the recent past again we are finding more of them coming to our clinics. It is probably due to the Aarogyasri scheme which is providing them financial support to come to the big hospitals for special care. The disease presentation in the hospitals is dependent on many aspects and one may get misguided if the disease presentation is not understood. Buerger's disease still persists in our low socioeconomic group of people.
