The Relationship

Background: The techniques described for the identification of the lumbosacral (LS) epidural space in dogs do not guarantee the needle position or an accidental subarachnoid puncture, especially in small size dogs.Aim: To determine the relationship between body weight and the location of the dural sac (DS) using myelography in dogs, and to determine the possibility of subarachnoid puncture during LS epidural based on the position of the DS.Methods: Four masked observers evaluated 70 myelographic studies of dogs, annotating the vertebrae where the DS ended, if it was localized before or after the LS space, and if accidental subarachnoid puncture during LS epidural injection was possible (yes/no). Body weight (kg) was categorized into: less than 10 kg, between 10 and 20 kg, and more than 20 kg and was also converted to body surface area (BSA) as a continuous variable.Results: The DS ended at the LS space or caudally in 50% of dogs. There was a statistically significant difference between the position of the DS and the dog’s BSA (p = 0.001). The DS ended caudal to the LS space in 72.7% of dogs weighing <10 kg, in 25% of dogs between 10 and 20 kg and in 15% of dogs in the >20 kg category. The observers considered a possible subarachnoid puncture during LS epidural in 69.7% of patients <10 kg, 16.6% on those between 10 and 20 kg, and in 11.7% of the dogs >20 kg.Conclusion: The DS ended caudal to the LS space in almost 3/4 dogs in the <10 kg category, so accidental subarachnoid puncture during LS epidural is highly possible in this weight range.

The relationship between body height and body weight has been described by using various terms. Notable among them is the body mass index, body surface area, body shape index and body surface index. In clinical setting the first descriptive parameter is the BMI scale, which provides information about whether an individual body weight is proportionate to the body height. Since the development of BMI, two other body parameters have been developed in an attempt to determine the relationship between body height and weight. These are the body surface area (BSA) and body surface index (BSI). Generally, these body parameters are described as clinical health indicators that described how healthy an individual body response to the other internal organs. The aim of the study is to discuss the use of BSI as a better clinical health indicator for preclinical assessment of body-organ/tissue relationship. Hence organ health condition as against other body composition. In addition the study is `also to determine the best body parameter the best predict other parameters for clinical application. The model parameters are presented as; modeled height and weight; modelled BSI and BSA, BSI and BMI and modeled BSA and BMI. The models are presented as clinical application software for comfortable working process and designed as GUI and CAD for use in clinical application.

Volume Formula

Abstract BACKGROUNDThe liver volume and spleen volum are useful index for cirrhosis patients with esphageal varices. But the calculation of the volume is time-consuming and boring. To solve the problem, we successfully established the liver and spleen volume formula using the body surface area. We compared the liver volume formula with other four formulas, which be proved with highest accuracy and lowest error. Until now, except for the new spleen volume formula in the research, there are few reports about it.AIMTo obtain a reference range of morphological indices, and to establish a formula to accurately predict the standard liver and spleen volumes in Chinese adults.METHODSComputed tomography was used to calculate the estimated total liver volume and spleen volume of 305 Chinese adults without any diseases which could influence the volumes of these two organs. Gender, age, body height, body weight, body surface area and body mass index were determined. Correlation analysis and step-wise multiple linear regression analysis were performed to evaluate the impact of each parameter on the liver and spleen volumes, and then a formula to predict the liver and spleen volumes was established. Finally, the results obtained with the new liver volume formula with existing formulas in a validation group were compared.RESULTSThe average liver and spleen volume values were 1043.18 ± 244.60 cm3 and 175.07 ± 88.15 cm3, respectively. Age, body height, body weight, body surface area and body mass index were significantly correlated with liver and spleen volume. Body surface area showed the strongest correlation with liver volume and spleen volume( p<0.005 and p<0.001). Based on these results, new formulas to calculate the standard liver volume and standard spleen volume were established.CONCLUSIONSCompared the new liver volume formula with the existing formula, it is found that the new liver volume is more accurate. And the accuracy of the spleen volume formula is acceptable. Core tip: To solve the problem of time-consuming and boring in calculating the liver and spleen volume, we successfully established the liver and spleen volume formula can be used in Chinese adult. Though there are some reports about the liver volume, but it is different in spleen volume. The liver volume and spleen volume radio is an useful index to predict the esophageal varices and bleeding risk for cirrhosis patients. Only liver volume formula is not enough, the finding of the spleen volume is very meaningful.

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.

Minute amounts of uniformly labeled C14 glucose were administered intravenously to unanesthetized normal and hypophysectomized dogs, in the postabsorptive state, as an initial priming injection, followed by a constant infusion. From the observed specific activity of the plasma glucose during the 60–180-minute period of the constant infusion, the following parameters of carbohydrate metabolism were determined: a) the size of the glucose pool, b) the glucose space and c) the rate of turnover of the glucose pool. The rate of total CO2 production was also determined. The rate of total CO2 production, per square meter of body surface area, was found to be less in the hypophysectomized dog than in the normal one. The glucose pool, per kilogram body weight, was found to be smaller in the hypophysectomized dog than in the normal one. The glucose space, expressed as percentage of body weight, was found to be similar in the two types of animals. The rate of turnover of the glucose pool in the hypophysectomized dog, presented as grams glucose per square meter of body surface area per hour, was found to be less in the hypophysectomized dog than in the normal one. The low rate of glucose uptake by the tissues which was observed to prevail in the hypophysectomized dog is believed to reflect an adjustment in the secretion of insulin to conform to the limited availability of endogenous glucose which results from the removal of the pituitary gland.

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.

Strategies for obtaining reliable results are increasingly implemented in order to reduce errors in the analysis of human and veterinary samples; however, further data are required for murine samples. Here, we determined an average factor from the murine body surface area for the calculation of biochemical renal parameters, assessed the effects of storage and freeze-thawing of C57BL/6 mouse samples on plasmatic and urinary urea, and evaluated the effects of using two different urea-measurement techniques. After obtaining 24 h urine samples, blood was collected, and body weight and length were established. The samples were evaluated after collection or stored at −20°C and −70°C. At different time points (0, 4, and 90 days), these samples were thawed, the creatinine and/or urea concentrations were analyzed, and samples were restored at these temperatures for further measurements. We show that creatinine clearance measurements should be adjusted according to the body surface area, which was calculated based on the weight and length of the animal. Repeated freeze-thawing cycles negatively affected the urea concentration; the urea concentration was more reproducible when using the modified Berthelot reaction rather than the ultraviolet method. Our findings will facilitate standardization and optimization of methodology as well as understanding of renal and other biochemical data obtained from mice.
