Organ weights in autopsy cases from an urban apex hospital.

The available limited anatomical and physiological data have been compiled for Indian adult as a part of ongoing efforts in the country to formulate an Indian Reference Man for radiation protection purposes. The parameters included weight, height, body surface area, weight of various organs (brain, heart, kidney, lung, liver etc.), total body water, extra-cellular water, blood volume, specific gravity, total lung capacity, vital capacity etc. The data have been drawn from post-mortem studies (566 males and 185 females) and other data from published work on 433 healthy male and 137 female volunteers. Data gaps have been filled by the method of pooling wherever necessary. This paper presents the intercomparison of the present data with the data available from other sources. The data from various Indian sources indicate a similar trend. However, a significant difference (P less than 0.01) was observed in organ weights and total body weights, in comparison to the Bhabha Atomic Research Centre (BARC) values. The present data are not comprehensive enough to suggest definitive norms of the Indian Reference Man.

Recurrent osteoid osteoma: a case report with imaging features.

We present a case of a 14-year-old boy, who presented with pain in the left thigh region for 1 year. The pain exacerbated at night, waking up the child and was relieved by salicylates. On the basis of clinical history, conventional radiography, computerized tomography and bone scintigraphy, a diagnosis of osteoid osteoma was made. The tumor was completely excised, and there was complete remission of symptoms. Six months following surgery, the pain recurred in the same region. Conventional radiography revealed dense sclerosis at the surgical site. Three-phase skeletal scintigraphy showed a focal area of increased blood pool activity followed by intense focal uptake in delayed images, characteristic of osteoid osteoma. Computerized tomography confirmed the findings of skeletal scintigraphy.
