Introduction. Malformations in kidney development and kidney diseases are accompanied with changes in their size. For kidney evaluation in clinical practice, the kidney length is the most widely used measurement, since it provides the most precise results and it is easy to perform. Recently, the measurement of relative renal length has become more preferable as it takes into account the body height. The aim of this study was to measure both the absolute and relative length of normal cadaveric kidneys according to the body height, sex and age. Material and methods. In this study, we examined 95 adult cadaveric kidneys, without renal and vascular impairment, their age ranging from 23-87 years. To determine the period of the most abundant changes in kidney length, we separated them into a 10-year range. The relative renal length was calculated using the kidney length anybody height ratio (kidney/body ratio). Results. The absolute and relative length of left kidney in males was longer than the right one, with a statistically significant correlation. In females, the left kidney length was also longer than the right one, however, without a statistical significance. In contrast to the absolute length, the relative length of both kidneys did not show a significant difference between sexes, and did not manifest a significant decrease with age. There was a significant correlation between the kidney length and the subject?s height. Conclusion. The relative renal length represents kidney size better than the absolute renal length because it eliminates sex and height differences until the age of 59 year. From the seventh decade of life, there is a significant decrease in both the absolute and relative renal length.

Introduction: Ultrasound is an important imaging modality used in the prognosis and diagnosis of renal conditions and diseases and also in the evaluation of kidney donors. This study aimed at providing a reference for the normal metric variables of the kidney such kidney lengths of healthy Nigerian adults in Lagos State and to compare with previously obtained results.Materials and Methods: This study was conducted in the radiology department of Ikorodu Hospital. This study adopted a descriptive cross-sectional study design with a cluster sampling approach which consisted of 150 adults (with 300 kidneys) participants ages 18-87 years. Real-time gray-scale ultrasonic scanning using Prosound 3500 Aloka device and a 3.5–5 MHz curvilinear explorer was employed for the abdominal imaging. The data acquired were compiled and explored via the Statistical Package for the Social Sciences (SPSS) version 20. The student’s t-test was utilized in probing for statistical significance between age as well as gender in relation to renal length. P-value < 0.05 was adjudged to be significant.Results: The kidney length was of a greater distance in males, and the length of the left kidney was more extensive than that of the right kidney in both sexes. Average kidney length was greater on the left when compared to the right among the various age groups. No significant association was noted between kidney length and age as well as gender.Conclusions: Normal values for kidney length and diversifications in the kidney length of healthy adults in Nigeria have been established.

The cardiovascular system consists of a pump represented by the heart and blood vessels, which provide the route by which blood circulates to all parts of the body. William Harvey, in the 17th century, discovered that blood is pumped away from the heart, but it all returns to the heart after circulating in the body. A right ventricular function can be compromised by pressure or stress, often secondary to the right heart valve or muscle pathology. The valves maintain unidirectional flow and permit increased pressure to develop in the chambers. The tricuspid valve consists of three tissue flaps. It separates the right atria and the right ventricle. To measure morphometric measurements of an individual leaflet of the tricuspid valve of cadaveric human hearts. The material for the present study comprised of 50 formalin-fixed adult human hearts (35 males and 15 females) which were obtained from the Department of Anatomy from various medical colleges in Maharashtra. Statistical significant difference was found for the height of anterior and posterior leaflets between male and female hearts. The length of the septal leaflet was also found to be statistically significant between male and female hearts. The study will be helpful for cardiac surgeons in providing data for tricuspid valve complex, leaflets, cords and papillary muscles.

The main aim of this study was to define the quantitative neuromuscular characteristics of Biceps Femoris muscle (BF) as the knee joint flexor, i.e. the major synergist of caudal body in all specific movement tasks of a football player, measured by tensiomyography (TMG) method . The secondary aim of the study was to compare all TMG-BF characteristics in relation to bilateral dimorphism, as well as to compare dominant and non-dominant legs. The research was conducted on a sample which included 54 professional players of age 23.0 ± 4.4 years; body height: 182.6 ± 15.1 cm; body mass: 81.2 ± 15.1 kg; BMI: 23.3 ± 1.2 kg/cm2. TMG variables were measured on the muscles during a transition training phase (mid-season and end of the season). The results have shown that the average Tc - 32.19 ± 7.64 and 33.21 ± 8.88 ms, Td - 25.56 ± 3.58 and 25.44 ± 3.20 ms, and Dm - 7.39 ± 1.87 and 7.52 ± 2.50 mm, for dominant and non-dominant leg, respectively. The results have indicated that there was no statistically significant difference between the examined TMG variables of dominant and non-dominant leg (Wilks' lambda Value = 0.979, F=0.300, p=0.952, Part. Ƞ2 = 0.021). It may be stated that there are no differences in the manifestation of neuromuscular characteristics in healthy elite football players regardless of their dominant leg. A high level of preparedness in football in addition to a completely healthy status of the body and locomotor system result in a complete neuromuscular contractile symmetry BF of both legs.

Abstract The body temperature of 10 clinically healthy green iguanas (Iguana iguana) was measured using a thermographic camera (FLIR E6, Flir Systems Sweden) before and after the food was offered. For each animal there were performed a total of 6 measurements (3 before feeding and 3 after the food was offered). The purpose of this experiment was to observe the thermographic pattern of the body before and after the feeding, since herbivore reptiles tend to bask after the feeding to increase the body temperature that will help them afterwards digest the food. The animals were housed in individual vivariums with every animal having a basking spot available. The pictures were taken outside the vivarium in an adjacent room. The animals were handled with gloves and transported in a cardboard box in order to avoid heat transfer between the handler and the iguana that would have produced thermal artefacts. Each individual was placed on a table on a styrofoam slate, again, to avoid the heat transfer between the table and the animal`s body. For each animal a total of 4 pictures were taken (up, front, left and right). The pictures were analysed with the FLIR Tools program that is provided by the manufacturer and 3 temperatures were taken into consideration (the head temperature, body temperature on the right side and body temperature on the left side). The temperatures were compared between them and with the temperature of the vivariums that consisted of the average between the temperature in 3 different spots (basking spot, the feeding bowl site and the coldest spot) measured with an infrared thermometer GM300 (Benetech, China). The temperature of the body was dependent on the vivarium temperature and it was a significant temperature difference between the measurements before the feeding and after the feeding. Also we discovered a significant difference between the head temperature and the body temperature on the left side before the feeding that disappeared after the animals ate. There was also a significant difference between the temperature on right side and on left side of the animals both before and after the feeding. No significant temperature difference was observed between the head and the right side of the body neither before nor after the feeding.

Abstract Background and Aims Kidney size has been found to be correlated with anthropometric features and is different among different ethnicities. In this study, we used ultrasonography for measurement of kidney volumes in healthy individuals and evaluated the relationships with body height, age and gender. Method We conducted a cross-sectional observational study and evaluated 108 healthy individuals whose serum creatinine level was within reference range. Patients’ medical clinical and laboratory records were reviewed. Age, gender and height were recorded. Pearson correlation coefficients were used to evaluate the strength of association between ultrasonographic parameters with each other and with other parameters, and were expressed as r2. Variations in left and right renal dimensions between various age groups were compared using a one-way analysis of variance, followed by a post-hoc Tukey's test. Results Subjects’ age ranged from 16 to 84 years and the mean age was over 50 years. There was an equal distribution among genders. Strong and positive correlations were seen for the measured length, parenchyma thickness and also for both total and parenchymal volumes with subjects’ height for both kidneys. The strongest correlations were observed for the left and right kidney length and also for the right kidney parenchymal volume (r=0.536, p=0.001; r=0.469, p=0.001; r=0.44, p=0.001). On the opposite, most of the relations with age were negative, but week and insignificant. When we divided the study subjects into three age groups and compared them for the height, there was no significant difference among them. Regarding the parenchymal and total kidney volumes of both kidneys, the different age groups showed similar findings in the ultrasonographic measurements. The mean calculated volumes were slightly declining with age and showed the largest values in the first group of patients under 30 years and lowest values in patients over 70 years old. Ultrasonographic measurements were also compared among the two genders. Both (men and women) showed similar age (53.55 ± 18.22 vs. 50.79 ± 18.13 p= 0.430, respectively). As for the height, men were significantly taller than women (1.734 ± 0.007 vs.1.637 ± 0.005, p= 0.001). The kidney length, volume and parenchymal volumes of both kidneys were significantly larger in men. Conclusion Renal length and volume are strongly correlated with body height. This relation must be considered in clinical decisions on further investigations regarding kidney disease progression.

Abstract Abstract 5177 Background. Renal dysfunction has been reported in adult subjects with thalassemia major (TM) since 1975. One of the main cause is the iron overload consequent to regular transfusions. Multiecho T2* MRI is a well-established technique for cardiac and hepatic iron overload assessment, but there very few report concerning the kidneys. The aims of this study were to describe the T2* values of the kidneys in patients with TM, to investigate the correlation between renal and myocardial or hepatic siderosis and biventricular cardiac function. Methods. 119 TM patients (58 men, 30. 7 ± 8. 2 years) enrolled in the Myocardial Iron Overload (MIOT) networks underwent MRI. For the measurement of iron overload, multiecho T2* sequences were used. The left ventricle was segmented into a 16-segments standardized model and the T2* value on each segment was calculated as well as the global value. In the liver, the T2* value was assessed in a single region of interest (ROI) in a homogeneous area of the parenchyma. For each kidney, T2* values were calculated in three different ROIs and were averaged to obtain a representative value for the kidney. The mean T2* value over the kidneys was also calculated. Cine images were obtained to quantify biventricular morphological and functional parameters in a standard way. Results. T2* values in the right kidney were significant lower than in the left kidney (40. 3±11. 9 ms vs 44. 1±12. 7 ms, P<0. 0001). The mean T2* value over the kidneys was 42. 2±11. 9 ms and 40 patients (33. 6%) had a pathological value (T2*<36 ms, lower limit of normal evaluated on 20 healthy subjects). The mean T2* value did not show a significant difference amongst men ad women (43. 2±11. 7 ms versus 41. 3±12. 1 ms, P=0. 378). The mean T2* values increased with age in a significant manner (r=0. 321, P<0. 0001). There was a significant negative correlation between serum ferritin levels and mean renal T2* values (r=-0. 446, P<0. 0001). Significant positive correlations of the mean T2* values were demonstrated for liver (r=0. 511, P<0. 0001) and global heart (r=0. 262, P=0. 004) T2* values (Figure 1). No correlation was found between renal iron overload and bi-ventricular function parameters. Conclusions. Systemic T2* differences between left and right kidneys were found, with significant lower values in the right one. Mean T2* value increased with age. We confirmed that kidney iron deposition was not very common in TM, but it was correlated with iron deposition in liver and heart. Disclosures: No relevant conflicts of interest to declare.

The study of the constitutional features of organs in the healthy population makes it possible to find out the peculiarities of changes in their sizes in different pathologies. The purpose of the work is to construct and analyze the regression models of individual sonographic sizes of the kidneys in practically healthy women of the ectomorphic somatotype, depending on the features of anthropo-somatotypological parameters of the body. From the database of research center of the National Pirogov Memorial Medical University, Vinnytsya (within the framework of the agreement on scientific cooperation) were taken the primary sonographic parameters (length, width, front and rear size, area of the longitudinal and cross section of the kidneys and their sinuses, as well as the volume of the right and left kidneys) and anthropometric indices (according to V. V. Bunak in the modification of P. P. Shapаrenko) of practically healthy women-ectomorphs of the first mature age, who in the third generation live in the Podillia region of Ukraine. Regression models of individual sonographic sizes of the kidneys, depending on the features of anthropo-somatotypological parameters of the body, are constructed using the license package “Statistica 6.1”. In practically healthy women of the ectomorphic somatotype all 16 possible reliable regression models of sonographic parameters of the right and left kidneys, based on the anthropometric and somatotypological parameters with determination coefficient R2 from 0.607 to 0.973, were constructed. Constructed regression models of sonographic parameters of both kidneys in practically healthy women of the ectomorphic somatotype most often include body diameters (24.2% of the total number of indicators included in the models), circumferential body sizes (20.9%), cephalometric indices (19.8 %) and the thickness of skin and fat folds (14.3%). The regression models of sonographic parameters of the right kidney in women of the ectomorphic somatotype most often include diameters and circumferential body sizes (by 27.3% of the total number of indicators included to the models of right kidney) and cephalometric indices (18.2%). The regression models of the sonographic parameters of the left kidney in women of the ectomorphic somatotype most often include body diameters and cephalometric indices (by 21.3% of the total number of indices included to the models of the left kidney) and the circumferential body size and thickness of skin and fat folds (by 14.9%).

Purpose: Previous studies reported a peripheral immune asymmetry and lateralization of different paired organ cancers. Because of the close relationship of immune system with body temperature, the aim of the study was to test the possible lateralization of skin temperature. Materials and Methods: Four hundred sixty three healthy subjects (325 women, 138 men) with an average age of 23.62 years (SD = 8.65) participated in this study. All skin temperature measurements were done 8:00-9:00 a.m. Skin temperature was assessed for three different points in skin: axillary, thumb and external auditory. Results: Skin temperature was statistically significantly higher on the right side of the body than on the left side, when measured by axillary and thumb temperatures. But there was no statistically significant difference in external auditory temperature. Conclusion: The asymmetry of skin temperature may result from the peripheral immune asymmetry or the asymmetric lymph node distribution.

Aim. To show the variety and severity of the clinical symptoms of a rare hereditary disease — Вardet — Biedle syndrome — in a14-year-old girl. Materials and methods. We carried out a retrospective analysis of anamnestic data, the course of the disease, laboratory and instrumental data, as well as the therapy of a 14-year-old patient with Вardet-Вiedlе syndrome. Results. A 14-year-old patient with hereditary Вardet — Вiedlе syndrome (polydactyly, mental retardation, progressive obesity, pigment retinopathy) was found to have a congenital abnormality of kidney development — hypoplasia and dysplasia of the only right kidney complicated by chronic secondary pyelonephritis with the development of chronic kidney disease. Urine tests revealed leukocyturia, bacteriuria and proteinuria. The echo-signs of diffuse changes in the parenchyma of the right kidney were found during the ultrasound kidney examination. The left kidney was not determined. The conclusion of dynamic renal scintigraphy: the image of the left kidney is not reliably visualized (a sharp decrease in the function or absence of the kidney), the preserved filtration function and a moderate decrease in the excretory function of the right kidney. Intoxication syndrome, leukocyturia, bacteriuria and proteinuria were relieved against the background of antibacterial (Ceftriaxone) and symptomatic therapy. Conclusion. We have described a clinical case of the Вardet — Вiedlе syndrome with congenital kidney malformation (impaired function), but with the normal structure of the internal reproductive organs and sexual development. In the future, due to the development of chronic kidney disease, the patient should receive specialized nephrological care, as well as be observed by endocrinologist due to a high risk of developing type 2 diabetes mellitus.

Almost all processes in the human body in one way or another connected with the autonomic nervous system. That's why it is real to evaluate the functional state of the person by temperature characteristics of representative points of the autonomic nervous system. Location and information of these points are confirmed by fundamental research. However, simply measuring the temperature at some points may not be sufficient to establish any systematic changes in the human body. The establishment of such changes requires systematic assessment of interdependent significant relationships between these parameters.The main aim of our research was to study effects of myocardial infarction in the thoracic region of the autonomic nervous system. The temperature of representative areas of the thoracic autonomic nervous system we measured by infrared thermometer (Medisana FTO D-53340 , with an accuracy of 0.1 degree Celsius). Statistical analysis was conducted in the packet Statistics 10. The presence of a difference in the temperature coefficients of representative areas (p<0,05). For the left side of the spine characterized by a difference in Th1–Th5 segments, which confirms their diagnosis: Th1 – 0,931,12 (control) and -0,797,49 (experiment), Th2 – 1,571,12 and -0,486,70, Th3 – 1,582611,12325 and -0,663,36, Th4 – 0,85913 0,92611 and -1,74,64, Th5 – 0,923480,75469 and-1,615,73 respectively. For the right side of the thoracic spines: Th6 – 0,850,73 (control) and -0,797,49 (experiment), Th7 – -1,000,79 and -1,370,69, Th8 – -0,960,73 and -0,990,68, Th9 – -0,120,64 and -0,380,83, Th10 – -0,921,14 and -1,031,00, Th11 – -1,691,05 and -1,861,06, Th12- -1,651,15 and -1,961,12 respectively. We found that myocardial infarction is manifested in the thoracic spine. In an experimental group there is significant difference of temperature in all segments. We can also notice asymmetry of temperatue between the right and left side of the spine. In the test group there are a deviation from the normal temperature in the first five thoracic segments on the left side, which confirms their diagnosis. On the right side of the spine there are a deviation in the last seven segments, which may indicate the compensatory mechanisms of regulation of the system. We can observe the temperature asymmetry, which in long-term exposure can negatively affect to the body.
