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)
BACKGROUND Oral cancer is the most common cancer in Indian males and is the third most common cancer in Indian females. Tobacco, alcohol, areca nut, and human papillomavirus (HPV) are the common etiologic factors. Each of these agents follows a unique model of carcinogenesis that leads to a certain distinct presentation and behavior. For example, HPV is(More)
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)
Rational understanding of etiopathogenesis of the systemic complications arising out of sudden, severe alterations in structure and function of the skin consequent to the syndrome of acute skin failure clearly establishes the necessity of a dedicated ICU in a skin department. Immune suppression due to increased age, organ transplantation, malignancy,(More)
Granuloma faciale (GF) is a rare cutaneous disorder characterized by one to several soft, erythematous to livid papules, plaques or nodules, usually occurring on the face. Extrafacial lesions are uncommon. A 52-year-old lady with multiple asymptomatic, variously sized brownish-black colored, firm, sharply circumscribed plaques resembling keloids on both(More)
BACKGROUND Toxic epidermal necrolysis (TEN) is a drug induced acute life threatening condition with mortality ranging from about 15 to 60%. A 'severity of illness' score termed as SCORTEN has been developed to predict mortality in TEN cases at the time of admission. It is calculated by giving one point for each of predetermined seven variables, evaluated(More)
OBJECTIVE The aims of this study are to evaluate the impact of frozen section in achieving adequate surgical margin and to study the accuracy of frozen section in detection of occult metastases. MATERIALS AND METHODS This was a retrospective review of prospectively collected data of 877 patients with squamous cell carcinoma of the tongue who underwent(More)
Mandibular metastasis due to thyroid carcinoma is not very frequent and the cases described in the literature are few. Due to its bloodstream dissemination, most of them are a consequence of the follicular variant of thyroid carcinomas. We are presenting a case in which the metastatic lesion of mandible was detected before diagnosis of primary malignancy.
BACKGROUND The cost-effectiveness of the frozen section for assessment of margin in head and neck squamous cell carcinoma (HNSCC) is still contentious. The purpose of this study was to evaluate whether gross examination of margin is an alternative to frozen section. METHODS It was a prospective observational study in 145 consecutive patients undergoing(More)
