OBJECTIVES To evaluate the prognostic role of the lymph node ratio (LNR; ratio of total positive nodes to total dissected nodes) in oral squamous cell carcinoma (OSCC) as compared to pN staging with an aim to provide an optimal cut-off value. METHODS 1,408 OSCC previously untreated patients who underwent treatment (surgery + neck dissection + adjuvant(More)

BACKGROUND Extreme sub-zero temperature in winters (15 °C to -25 °C), high velocity winds and wind-chill factor pose risk to those who resides at the high altitude environment to develop cold related injuries like chilblains and frostbite. The aim of this study was to study the patterns of chilblains in high altitude region like Ladakh. METHODS The study(More)
