These correlations are intended to aid in pre-operative planning and mandibular implant design. The analysis was performed on 30 male (25.46 ± 4.3 years) and 20 female (27.94 ± 4.2 years) South African specimens, by retrospectively analysing CT scan data. Results of the study showed a number of moderate to strong correlations existing between mandibular measurements. Conversely, no strong correlations existed between upper facial and mandibular measurements. The strongest correlations existed between bilateral mandibular measurements. This supports the intuitive observation of the mandible being symmetrical across the sagittal plane. A comparison was also drawn between certain measurements across different ethnic groups. The significant differences in measurements across these ethnic groups emphasises the need for an analysis specific to the South African population.","PeriodicalId":165912,"journal":{"name":"2018 3rd Biennial South African Biomedical Engineering Conference (SAIBMEC)","volume":"110 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124082918","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The external ear was investigated as a novel location for a wearable device that monitors core temperature, heart rate, respiratory rate and blood oxygen saturation (SpO2) A proof of concept, called the Ear Monitor, was designed and built to test the feasibility of such a device. A trial was conducted on a group of 16 participants. Measurements were compared to benchmark measurements recorded by commercially available devices. The following results were obtained: Core temperature was measured with a mean error of 0.018 ± 0.516 °C. Heart rate was measured with a mean error of 0.031 ± 0.717 beats per minute. Respiratory rate was measured with a mean error of −0.558 ± 1.406 breaths per minute. Finally, SpO2 was measured with a mean error of −0.22 ± 1.50%. All measurements showed statistically significant correlation with their respective benchmark measurements (p < 0.05), except for SpO2. The latter is due to the absence of measurable SpO2 variations in healthy individuals during the trial. It is concluded that the external ear is a suitable location for measuring core temperature, heart rate and respiratory rate. Further testing is needed to evaluate the SpO2 measurement capabilities of the device.","PeriodicalId":165912,"journal":{"name":"2018 3rd Biennial South African Biomedical Engineering Conference (SAIBMEC)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129004268","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to determine BMD values of healthy/normal lumbar spines to further define and investigate possible population variation/s. 82 CT-scans from Steve Biko Academic Hospital (Pretoria) were used, of which 36 were females (22 black; 14 white) and 46 males (32 black; 12 white). Lumbar vertebrae (L1-L5) were analysed at cortical regions: the superior (SEP) and inferior endplates (IEP) and the anterior (AB) and posterior borders (PB) as well as medullary regions: 3 regions of interest (ROIs). Ranges (in Hounsfield Units) were: Cortical: black males, 522.68–541.11; white males, 479.51–507.89; black females, 496.91–520.04; white females, 484.50–517.08. Medullary: black males, 230.38–236.50; white males, 201.18–210.91; black females, 211.04–222.60; white females, 195.24–208.72. IEP was denser than SEP, and PB denser than AB for most measurements. ROI2 was the lowest and ROI3 the highest for most measurements. Black males surpassed black females, but the opposite was seen for several white cortical measurements. Overall, black individuals showed higher BMD values than white individuals. Awareness of differences in South African populations could aid in allocating interventions suitable for specific patients.","PeriodicalId":165912,"journal":{"name":"2018 3rd Biennial South African Biomedical Engineering Conference (SAIBMEC)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130086539","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
