IntroductionThe anatomical knowledge of bone depressions and elevations of the distal humerus region is important for planning surgical procedures. The supratrochlear septum, located superiorly to the trochlea, can be perforated, originating an anatomical variation known as supratrochlear foramen (STF). The occurrence rate of this variation is between 0% and 60% and reaches different ethnicities. The STF is commonly associated with the presence of a narrow medullary cavity, which could complicate some surgical procedures to correct fractures of the distal humerus region. In radiological evaluations, the presence of the STF can cause a wrong interpretation, being confused with a cystic or osteolytic lesion.ObjectiveMeasure anatomical structures present in the humerus distal region to determine the morphology of this region, in human adult humeri. Detect the presence of the STF and calculate its size.Material and methods48 dried humeri of brazilian male adult cadavers, were selected from the collection of the Department of Morphology of Santa Casa de São Paulo School of Medical Sciences. All humeri were submitted to several measurements, with the help of two digital calipers. The measurements taken are represented in figure 1. The study was performed by two independent observers, who did three measurements of each of the evaluated items, at different times and blindly, totaling six measurements per bone. The values obtained by the observers were submitted to statistical analysis (SPSS 21.0) in order to determine the intraobserver and interobserver correlations. The intraclass correlation coefficient (ICC) and the Pearson's correlation coefficient were used, respectively.ResultsOf the 48 dried humerianalized, 28 (58,33%) were right side and 20 (41,67%) were left side. The results of the measurements taken are presented in table 1. The Intraobserver and interobserver correlations are represented in tables 2 and 3, respectively. About the STF, it was found in 13 (27,09%) of 48 studied bones, six (46,15%) on right side and seven (53,85%) on left side. Our presence of STF was similar to the results found by 13 authors in the literature, variating from 19,20% to 39,00%. As demonstrated in tables 2 and 3, the measurements whose values are highlighted in green had intraobserver and interobserver correlation coefficients very high (r ≥ 0,9), unlike depression measurements (mainly the olecranon fossa), probably because of the difficulty to stipulate which is the exact location of its beginning and end.ConclusionThe interepicondylar distance, supretrochlear septum thickness and diameters of the STF, when present, were reproducible by the two observers, being considered the best measurements to describe this region. The presence of the STF in the analyzed humeri was relevant, showing that it is an anatomical variation relatively frequent. This fact should be known by all professionals who are involved in the diagnosis and treatment of affections of the humerus distal region, in order to choose the best therapeutic option to be followed.Support or Funding InformationPiBic CNPq 2018This abstract is from the Experimental Biology 2019 Meeting.

INTRODUCTION Medical education can affect physical and mental health of students as well as their quality of life. Contact with pain, death, poor quality of public health system and strenuous medical programs influences their quality of life. Besides, frustrations with the insecurity regarding their professional future were also reported to enhance the stress. Based on this, we propose a Hatha Yoga program trying to improve the quality of life of medical students from Santa Casa de São Paulo School of Medical Sciences (São Paulo – Brazil). MATERIAL and METHODS Self‐perception of life quality was evaluated in first and second‐year students from Morphology Department. The World Health Organization Quality of Life Assessment (WHOQOL‐BREF) was offered for all students. Students who have shown WHOOQL‐BREF score under 50% were invited to participate of this study. For selected students, the Short‐Form Health Survey (SF‐36) was offered before the first Hatha Yoga class. The evaluation of the SF‐36 results was done by attributing scores to each question, which were then transformed into a scale ranging from 0 to 100, where 0 corresponds to the worst quality of life and 100 to the best. Twenty‐four Hatha Yoga classes including Pranayama (breathing exercise, 5’), Asanas (postures, 35’), Yoganidra (relax, 5’), Dhyana (meditation and Yoga Theory, 15’) were offered twice a week in the last three months of Anatomy course. After last Yoga Class, another SF‐36 was applied and dimensions of social aspects, mental health, emotional health and vitality was compared and t‐paired test was used to show statistical significance. RESULTS 240 students were invited to participate and 50 answered WHOOQL‐BREF. 69.9% students (n=32) has shown WHOOQL‐BREF score under 50.0% and 82.1% reported pain and discomfort, 75.0% exhibit dependence on medication and 80.7% related negative feelings. All of 32 students were invited to participate of this study and 16 accepted the invitation and were included in this study. First SF‐36 has shown impairment in social aspects (44.5 ± 19.7), mental health (40.8 ± 17.4), emotional health (16.6 ± 24.4) and vitality (28.4 ± 16.4). These data were compared to last SF‐36 and have shown statistical significance in all of parameters: social aspects (73.3 ± 24.4 p<0.001), mental health (65.2 ± 20.5 p< 0.001), emotional health (56.2 ±45.1 p=0.001) and vitality (59.1 ± 20.7 p<0.001). DISCUSSION and CONCLUSION We believe that Hatha Yoga offers a comprehensive solution for managing medical student’s health as a whole and it can lead to reduction of stress levels. Reduction in perceived stress levels results in lesser negative feelings, lower anxiety and depression and improved sense of well‐being, and better sensory‐motor performance. Yoga seems to contribute to improvement of life quality and enhance the concentration and learning. Teaching medical students to relate mindfully to current internal and external stimuli, through yoga, can decrease mental distress, improve students’ academic performance and increase well‐be...
