Bone Age Determination of Epiphyseal Fusion at Knee Joint and Its Correlation with Chronological Age.

Background and Objectives: Bone age determination is a valuable method for forensic and disaster identifications of unknown human remains, as well as for medical and surgical procedural purposes. This retrospective research study aimed to determine the age based on epiphyseal fusion stages and investigate differences related to gender. Materials and Methods: X-rays of the knee were collected from medical imaging centers in hospitals in the south of Jordan and examined by two observers who determined the bone epiphyseal phase of closure for the femur, tibia, and fibula bone ends close to the knee based on a three-stage classification. Results: The main results revealed that females showed earlier epiphyseal union (Stage II) at the lower end of the femur and the upper ends of the tibia and fibula compared to males. In males, the start of complete union (Stage III) at knee bones was seen at the age of 17-18 years, while in females, it was seen at the age of 16-17 years. Additionally, knee bones showed complete union in 100% of males and females in the age groups 21-22 years and 20-21 years, respectively. Although females showed an earlier start and end of epiphyseal complete union than males, analysis of collected data showed no significant age differences between males and females at the three stages of epiphyseal union of the knee bones. Conclusions: Findings of the radiographic analysis of bone epiphyseal fusion at the knee joint are a helpful method for chronological age determination. This study supports the gender and ethnicity variation among different geographical locations. Studies with a high sample number would be needed to validate our findings.

Medical students' perceptions of factors that Impact their performance in human physiology course: suggestions for improving course presentation.

OBJECTIVES: The study aims to examine students' perceptions of factors that impact students' performance in the Human Physiology course at HU's College of Applied Health Sciences and their suggestions for improvement. METHOD: A cross sectional study was conducted between March 2022 and April 2022. A self-administered online questionnaire was distributed to undergraduate students in Physiology courses (online and blended) via Microsoft Teams. Data were analyzed descriptively and inferentially, and thematic analysis was employed based on the most frequent statements for the open-ended question. RESULTS: In total, 435 students participated in the study. Results indicated that students had high levels of agreement (M = 4.39) regarding faculty teaching style compared to (M = 4.24) towards course content and (M = 3.49) moderate levels towards technological aspects. In terms of the statistically significant differences at (α = 0.05) in students' perceptions of factors that influence their performance due to the variables (gender, GPA, college, and teaching methods: online or blended), results showed that course content was not affected by any variables. The technological aspects were affected by GPA and gender. In terms of faculty teaching style, it was affected by all variables (GPA, college, and teaching method) except gender. One open-ended question regarding suggested improvements revealed four main themes: assessment and evaluation, technical issues, teaching methods and tools, and Arabic language support. CONCLUSION: The study findings recommend greater use of assessment for learning methods and provision of interactive materials to help medical students overcome the challenges that might impact their performance.

Cystic echinococcosis in Jordan: A review of causative species, previous studies, serological and radiological diagnosis.

Cystic echinococcosis (CE)/hydatidosis is a zoonotic disease which occur in human and herbivore animals as a result of infection with the larval stage of the taeniid cestode Echinococcus granulosus sensu lato (s. l.). In human, CE is a serious public health concern in many parts of the world including Jordan. The present review will cover CE causative agent: E. granulosus species/genotypes; life cycle of E. granulosus parasite, all published previous studies on CE in Jordan (humans, intermediate hosts, definitive host) as well as its diagnostic methods in human.

The role of magnetic resonance imaging in the diagnosis of Parkinson's disease: a review.

Parkinson's disease (PD) is the second most common neurodegenerative disease after Alzheimer's in elderly people. Different structural and functional neuroimaging methods play a great role in the early diagnosis of neurodegenerative diseases. This review discusses the role of magnetic resonance imaging (MRI) in the diagnosis of PD. MRI provides clinicians with structural and functional information of human brain noninvasively. Advanced quantitative MRI techniques have shown promise for detecting pathological changes related to different stages of PD. Collectively, advanced MRI techniques at high and ultrahigh magnetic fields aid in better understanding of the nature and progression of PD.
