Body surface area (BSA) was actually measured in 13 Indian Hindu children, of ages varying between 3 and 12 yr, with tape and surface integrator. In 9 out of 13 children the results obtained were lower than the BSA calculated with the weight-height formula of Du Bois and Du Bois. Based on the actual measurements, a new constant for the weight-height formula was obtained and a new equation: surface area, cm2 = weight 0.425 kg x height 0.725 cm x 70, has been suggested for the BSA of Indian children. A nomogram for reading off surface area in metric units based on the above formula was prepared. A significant difference existed between the BSA calculated with the new formula and that of Du Bois and Du Bois. Submitted on December 30, 1960

Introduction: The purpose of this study was to establish reference ranges of total thyroid volume among clinically euthyroid Nepalese population using Ultrasonography and correlate this volume with age, sex, individual’s built and geographic location. Methods: This was a prospective cross sectional study involving 485 clinically euthyroid individuals. B - mode Ultrasonography was used to measure the total thyroid volume by combining the volume of both the lobes obtained by using formula for prolate ellipsoid. Age specific reference values for thyroid volume were obtained and Pearson correlation test was used to see the relationship with various factors. Results: Among 485 individuals between 1 to 83 years of age, 221(45.57%) were males and 264(54.43%) were females. Maximum [354 individuals (72.99%)] were from hilly region and minimum [16 individual (3.30%)] were from Himalayan region. Mean thyroid volume was 6.629 ± 2.5025 ml. In general, thyroid volume was found to be more in older individuals than in young age group. There was no significant difference of thyroid volume between males and females. Thyroid volume best correlated with body surface area (r=0.444, p<0.0001). The volume had a positive correlation with weight (r=0.443, p<0.0001), body mass index (r=0.371, p<0.0001) and height (r=0.320, p<0.0001) of the individual. Conclusions: This study estimated the reference range of total thyroid volume for Nepalese population. These ranges are significantly lower than the WHO/ICCIDD thyroid volume references and reference values obtained in various other countries. Total thyroid volume best correlated with Body surface area.

The body surface areas of one normal and four extremely obese human subjects have been estimated by three methods: a) direct measurement by a method similar to that which Du Bois described; b) calculation from the Du Bois height-weight formula; and c) calculation from the Du Bois linear formula. The values for the total body surface area of the obese subjects calculated from the height-weight formula varied up to 11% below those that were directly measured. The values for the total body surface area obtained with the linear formula ranged between 13% and 20% above the direct measurements, this being almost entirely due to discrepancies in the trunk and in the thigh estimations. It has been concluded that estimation of the body surface area oxf extremely obese subjects by the Du Bois height-weight formula is satisfactory when considered in relation to the accuracy of the physiologic measurements with which it is generally used. Because of the unusual body form the Du Bois linear formula has been found unsatisfactory for this group. Submitted on March 1, 1960

Abstract Background There is increasing evidence that sex differences may influence responses after thermal injury and affect clinical outcomes. The objective of this study was to evaluate the relationships between sex, thermal injury, body size, and inpatient mortality in burn patients. Methods Medical records of adults with &gt;20% total body surface area (TBSA) burn injury admitted to two American Burn Association (ABA)-verified burn centers between 2008 and 2014 were retrospectively reviewed. Injury details and baseline characteristics, including body size as estimated by body surface area (BSA) and body mass index (BMI) were recorded, along with details of the hospital course. The primary outcome of inpatient mortality was compared between sexes. Results Out of 334 subjects, 60 were women (18%). Median TBSA was 33% (IQR 25–49) in this cohort, with 19% full thickness burns and 30% inhalation injury. Despite no significant difference in age, presence of inhalation injury, TBSA, or depth of burn, women had significantly higher rates of inpatient mortality (45 vs. 29%, P = 0.01). BSA was significantly lower in women vs. men (P &lt; 0.001), but this difference was not more pronounced among non-survivors. There was no difference in BMI between men and women non-survivors. Although not significant (P = 0.28), women succumbed to their injuries sooner than men (day 4 vs. 10 post-injury). Conclusions Women are less likely to survive burn injuries and die sooner than men with similar injuries. Body size does not appear to modulate this effect. Burn centers should be aware of the higher mortality risk in women with large burns.

AbstractThis study aimed to produce a weight-independent algorithm for determination of body surface area (BSA; cm2) to within 5% accuracy of the directly determined value in selected horses and ponies under field conditions. Quantification of BSA in equines has applications in the fields of energy budgeting, growth, thermoregulation, conformation and drug kinetics. A simple algorithm for determining BSA to ±5% accuracy was produced for Shetland ponies, Shire horses, Welsh Mountain Section A ponies and Hanoverian mature horses and foals. The accuracy of the method was ±8% for Welsh Mountain-type ponies and Hanoverian two-year-olds. The data were produced by tiling of the shoulder region on one side of the animal with chalk and adapting a simple geometrical integrative technique. Linear anthropometric measurements were of limited use in predicting BSA in that they produced algorithms of ±5% accuracy for ponies of uniform conformation only (Welsh Mountain Section A ponies). The relevant equations were: for Arab-based breeds (Welsh Mountain-type and Section A ponies and Hanoverian horses and foals) and for UK native breeds (Shetland ponies and Shire horses), where ‘surface area of shoulder region on one side’ was defined by the anterior margins of the supraspinatus and deep pectoral, and the posterior margin of the triceps muscles. This tiling procedure fulfilled the aim of the study and also provided quantitative information on proportional differences in areas of body regions between and within these selected breeds.
