Item Direct immunofluorescent studies of skin biopsies in pemphigus.(1994-01-01) Kumar, V; Arora, H L; Sareen, P M; Kumar, H SDirect immunofluorescent studies of skin biopsies from 16 pemphigus vulgaris patients revealed immunoglobulin deposits in 12 (75%) cases with fluorescence at intercellular areas in epidermis. In 2 patients (12.5%) dermoepidermal junction also showed immunoglobulin deposits. IgG was the commonest type of immunoglobulin demonstrated in 12 out of 16 (75%) cases followed by IgM in 5 (31.25%) and IgA in 1 (6.25%) cases. Seven (43.75%) cases showed presence of IgG alone while IgM with IgG was found in 4 (25%) cases. One (6.25%) case showed deposition of IgG, IgM and IgA. The results indicated that demonstration of immunoglobulin in skin biopsies by direct immunofluorescent technique is quite a useful adjunct in diagnostic confirmation of pemphigus.Item Osteoradionecrosis of mandible in patients treated with definitive radiotherapy for carcinomas of oral cavity and oropharynx. A retrospective study.(1992-04-01) Kumar, H S; Bihani, V; Kumar, V; Chaudhary, R K; Kumar, L; Punia, D PA retrospective analysis of 1140 cases of cancer of oral cavity and oropharynx treated with definitive radiotherapy was carried out with regard to the incidence and precipitating factors of mandibular osteoradionecrosis. 14 cases developed osteoradionecrosis out of which 10 had spontaneous mandibular necrosis and 4 had dental extractions in the area where osteoradionecrosis developed. Amongst the 10 cases of spontaneous osteoradionecrosis, 8 patients received doses of 6500 cGy in 6 1/2 weeks or 7000 cGy in 7 weeks by megavoltage cobalt 60 teletherapy and the remaining two patients received the doses of 6000 cGy in 6 weeks. The aforesaid 4 patients of osteoradionecrosis in the area of dental extractions had received doses of only 6000 cGy in 6 weeks.Item Pelvic bone metastasis from transitional cell carcinoma of the urinary bladder.(2003-01-19) Shah, Narender Singh; Kumar, Vanita; Sharma, Neeti; Anand, Vipin; Kumar, H S; Punia, D P
