Background: Thyroid carcinoma (TC) is the most prevalent head and neck cancer. Pre-clinical students lacked essential knowledge of thyroid cancer. Furthermore, clinical years medical students needed more awareness of thyroid screening and self-examination. Consequently, this study aims to identify the knowledge and understanding of thyroid cancer, among Umm Al-Qura University medical students in Saudi Arabia. Methods: A cross-sectional study was conducted on undergraduate medical students in the third to sixth year of a medical college using an online questionnaire from April to June 2022. Results: A survey of 297 medical students from the 3rd to 6th year found that 46.1% knew all early signs of thyroid cancer, while only 12.5% did not know any diagnostic tools. Most participants (74.4%) knew all desirable candidates for a thyroid cancer screen. 260 (87.5%) students answered positively that any unexplained lump or swelling could be an early sign of cancer. The gender of the participants had a significant correlation with many factors related to student knowledge of thyroid cancer, with gender having a substantial correlation with only two early signs. The student's grade point average (GPA) and academic year also had a significant correlation with many factors related to thyroid cancer knowledge. Conclusion: Thyroid cancer prevalence can be reduced by increasing public awareness and knowledge of risk factors. Students’ knowledge and participation in public education can lead to better results. In addition, increased public awareness about early signs of thyroid cancer can improve overall disease prognosis, morbidity, and mortality.

Due to lake of standardized methods to design and validate sun shading devices in Libya, this study aims at developing a solar chart, which can be used as a practical and systematic methodology for designing sun-shading devices in the city of Tripoli. In order to achieve the objective of this study, this paper was divided into five sections. The first section is dealing with a focused literature review with respect to types of shading devices and their impact on the exterior wall openings, the position of the sun, sun’s altitudes azimuths and how to mathematically be determined; the sun charts, and the shading calculator. While the second section was dedicated for the determination of the overheated periods over the year in which shading devices should be in place. The third section presents a computer software developed in order to automatically calculate the sun angles (Altitudes and Azimuth angles). The north latitude of 32.59 was chosen as a validation example. By using the Statgraphics software, the output data were analyzed and illustrated in a solar chart that presents the equinox, summer and winter solstices. The resulted solar chart serves as a tool, which will jointly be used with the shading chart to design accurate shading devices for the chosen North latitude 32.59. The fourth section explains the methodology of selecting an effective solar altitude and azimuth angles which an architect would on while designing sun shading devices. The fifth section, identifies and lists the methodology of designing each type of shading devices in the city of Tripoli. Libya. Finally, study conclusions were drawn, and further research studies were recommended to enhance the findings of this research paper.

Vaginal metastasis from pancreatic cancer is an extreme case and often indicates a poor prognosis. We present a case of pancreatic carcinoma with metastasis to the vagina that was discovered by vaginal bleeding. To our knowledge, this is the third case in the world of a primary pancreatic adenocarcinoma discovered of symptoms from a vaginal metastasis.

Adenoid cystic carcinoma of the cervix is a rare and aggressive tumor with fatal outcome. In this paper we report two cases of primary adenoid cystic carcinoma and a review of literature. A 80 years old woman, admitted to our hospital with postmenopausal bleeding and hydrorrhea. Gynealogical examination showed a cervical stenotic with the presence of a tumor processus. Biopsy of cervical growth was done. 80-year-old woman presented with vaginal bleeding with pelvic pain. Physical examination revealed a friable mass in the cervix. Incisional biopsy was performed. In the both cases the diagnosis of adenoid cystic carcinoma of the cercix was confirmed. Adenoid cystic carcinoma of the cervix is clinically and radiologically similar to other tumors of the cervix but the diagnosis can only be made by histological examination.

Abstract Background Breast cancer may be classified into luminal A, luminal B, HER2+/ER-, basal-like and normal-like subtypes based on gene expression profiling or immunohistochemical (IHC) characteristics. The aim of our study is to show the molecular profile characteristic of breast cancer in the North African population of Morocco. This work showed preliminary results and correlations with clinicopathological and histological parameters. Three hundred and ninety primary breast carcinomas tumor tissues were immunostained for ER, PR, HER2, CK5/6, CK8/18 and Ki67 using paraffin tissue. Methods We reviewed 390 cases of breast cancer diagnosed on January 2008 to December 2011 at the Department of pathology, Hassan II teaching hospital, Fez, Morocco. Age, size tumor, metastatic profile, node involvement profile, histological type and immunohistochemical profile were studied. Results The average age was 46 years; our patients were diagnosed late with a high average tumor size. Luminal B subtype was more prevalent (41.8%), followed by luminal A (30.5%), basal-like (13, 6%), Her2-overexpressing (9, 2%), and unclassified subtype (4.9%). Conclusion This study showed that molecular classification and biological profile may be different according to geographical distribution, to encourage further studies to know the genomic profile of tumors and the environment.
