It has encroached into so many disciplines and thus its relevance to career choice. This research work is aimed at assessing the perceptions of anatomy as a career choice among students studying human anatomy in Delta State University, Abraka, Nigeria. MATERIALS AND METHODS: Simple random sampling technique was used to select 384 participants (168 males and 216 females) from the 2nd to the 4th year studying human anatomy and cell biology in Delta State University, Abraka, aged 16–32 years. A self-administered questionnaire was used to obtain data for the study, and the data were analyzed using the Statistical Package for the Social Sciences (version 23). RESULTS: This study revealed that students with the perception of choosing anatomy as a career after graduation are significantly low compared to those who have no interest in anatomy as a career choice with the percentages of 39% and 61%, respectively. CONCLUSION: From the study conducted, human anatomy as a career choice has relatively low perception among students because anatomy was not their preferred course of study; rather, the course was offered to them on demerit on their first preferred course of study.","PeriodicalId":15815,"journal":{"name":"Journal of Experimental and Clinical Anatomy","volume":"1 1","pages":"49 - 54"},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82323770","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 aim of this study is to evaluate the effect of age, premedical academic performance, and entry bias on students' performance in final preclinical examination at the University of Nigeria Medical School. METHODS: Data were obtained from files of students admitted into the medical school in the 2010/2011, 2011/2012, and 2012/2013 academic sessions. SPSS (version 20.0, IBM computer USA) was used to analyze the data, and statistical tests such as ANOVA, Pearson's correlation, and regression analysis were used to analyze the observations. RESULTS: The younger students performed significantly better than their older counterparts in the final preclinical examination, determined by one-way ANOVA (P < 0.05). Students with high 100 level CGPA performed significantly (P < 0.05, ANOVA) better than those low CGPA. Only 100 level CGPA can predict students' academic performance in the final preclinical examination (R2 = 83.1%, P < 0.05). CONCLUSION: Age is an important criterion in the admission process. O-level grades, Unified Tertiary Matriculation Examination (UTME), and University of Nigeria Nsukka (UNN) post-UTME are reliable criteria for admission; however, of these, only 100-level CGPA can be used to predict students' performance final preclinical examination.","PeriodicalId":15815,"journal":{"name":"Journal of Experimental and Clinical Anatomy","volume":"16 1","pages":"6 - 11"},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87812977","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 different anatomical dimensions of paranasal sinuses can be obtained from plain radiograph and computed tomography images. Determining the possible significant variation of the right and frontal sinuses of males and females is essential for clinical purpose. PURPOSE OF THE STUDY: The purpose of this study, therefore, was to measure the anthropometric length and width of the frontal sinus on plain radiograph in different age groups and to determine the possible variations in males and females. MATERIALS AND METHODS: This descriptive cross-sectional study adopted the simple random sampling technique. The study population comprised 200 individuals (100 males and 100 females). RESULTS: Frontal sinus length and width were measured using the inelastic plastic ruler (in centimeter) and recorded on a data sheet pro forma. The mean total frontal sinus length and frontal sinus width across the entire population for both the right and left sides as regards males and females were given as (4.42 ± 4.79 cm, 3.85 ± 4.24 cm, 4.05 ± 4.44 cm, 3.57 ± 3.93 cm) and (3.64 ± 4.01 cm, 3.29 ± 3.46 cm, 3.23 ± 3.57 cm, 2.83 ± 3.13 cm), respectively. The Student's t-test statistics between the right and left sides in each of the studied parameters were highly statistically significant (P = 0.000). CONCLUSION: The frontal sinus is a constant structure in human beings, but shape and dimensions may vary among individuals; thus, the dimorphic nature of the left frontal sinus dimensions has implications for human identification.","PeriodicalId":15815,"journal":{"name":"Journal of Experimental and Clinical Anatomy","volume":"19 1","pages":"49 - 52"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88940022","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}

Diabetic foot problems are largely preventable and both care givers and the diabetic patient must place high priority on prevention through education. Health providers in developing countries are inadequate, overworked and do not have enough time to spend on health education of their patients. AIM: This study was carried out to evaluate the level of awareness of diabetes mellitus patients of complications of the disease seen in the foot in order to plan and execute effective health education programme to reduce complications. MATERIALS AND METHODS: This prospective study was carried out in the medical outpatient clinic of ESUT teaching Hospital Enugu from January to July 2015 using pretested structured questionnaire. RESULTS: 283 patients were sampled but only 260 supplied data for analysis. In the study, 150(57.7%) were females and 110(42.3%) were males. Age of the participants ranged from 32years to 88years, with mean age 0f 60.2years. Majority of the participants 258(99.2%) had been educated on common foot complications seen in diabetes mellitus. Only 70(27%) of the respondents could recognise loss of sensation in the foot as a sign of foot complication. CONCLUSION: Diabetic foot complication is still high in our diabetics and represents failure of preventive measures, requiring change of modality. Better education of diabetics must be emphasised in addition to any other attempt to curtail the problem.","PeriodicalId":15815,"journal":{"name":"Journal of Experimental and Clinical Anatomy","volume":"174 1","pages":"56 - 59"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76916951","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 requires detailed anatomical knowledge about the neurovascular bundle to avoid iatrogenic injury. AIM OF THE WORK: To study the topography of nerves and vessels at the tarsal tunnel in relation to surface anatomical landmarks. MATERIALS AND METHODS: The medial calcaneal region of 20 lower limbs of formalin preserved specimens was dissected. The neurovascular structures were identified within a quadrangle named ABCD, formed by four palpable bony landmarks, respectively: inferior tip of medial malleolus, posterior superior tip of calcaneal tuberosity, posteroinferior aspect of medial calcaneus, and tuberosity of navicular bone. A regression analysis was done to correlate the lengths of the four imaginary lines connecting the four bony landmarks with the location of the neurovascular structures. RESULTS: The posterior tibial artery was located medial to the tibial nerve in 50% of cases. The bifurcation of the artery was found to be proximal to that of the nerve in only one case. The number of the medial calcaneal nerves (MCNs) varied from 1 to 3 branches; the most common was one branch (50%). In two cases, there was high origin of the MCN at a distance of 15.4 and 23.5 cm proximal to the ankle region. CONCLUSION: The location of the neurovascular bundle at the tarsal tunnel could be predicted by measuring the distances between the anatomical bony landmarks.","PeriodicalId":15815,"journal":{"name":"Journal of Experimental and Clinical Anatomy","volume":"103 1","pages":"70 - 75"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78369464","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}

AIM OF THE STUDY: Thus, we investigated the cardioprotective efficacy of Nigella sativa oil (NSO) following dichlorvos dichlorvos (DDVP)-induced cardiotoxicity in Wistar rats. MATERIALS AND METHODS: A total of 24 Wistar rats were randomly divided into four groups (n = 6); the control was administered sunflower oil (1 ml/kg), DDVP (8.8 mg/kg) to the experimental Group I, whereas DDVP + NSO (8.8 mg/kg +1 ml/kg) and NSO (1 ml/kg) was administered orally to the experimental Groups II and III, respectively. The animals were euthanized; blood was transcardially collected from the right atrium, centrifuged, and plasma extracted to analyze levels of total cholesterol (TC), triglycerides, high-density lipoprotein cholesterol, and low-density lipoprotein cholesterol (LDL-C). While cardiac muscle tissue was collected from the left heart, processed and stained for general architecture (hematoxylin and eosin) and elastic morphology (orcein). RESULTS: DDVP significantly (P ≤ 0.05) increased the plasma levels of TC, LDL, atherogenic and atherosclerotic indices (TC/HDL-C and LDL-C/HDL-C ratios), but this was prevented by co-administration with NSO. Histological investigations showed that DDVP resulted in the pathological appearance of cardiac tissues, such as the lack of striations, myocardial hemorrhage, and necrosis-like features. CONCLUSION: It can be concluded that NSO was able to attenuate DDVP-induced cardiotoxicity.","PeriodicalId":15815,"journal":{"name":"Journal of Experimental and Clinical Anatomy","volume":"27 1","pages":"60 - 65"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80938250","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}
