Abstract: Previous technologies may not be able provide radio-opaque biodegradable polymers that are degraded and completely eliminated by the body and also have good visibility when implanted in a human or an animal body. The study of radio opaque bioresorbable polymer such as poly lactide [poly-L-lactide (PLLA), poly-D-lactide (PDLA)], polyglycolide, polydioxanone, polycaprolactone, or related copolymers materials, each of which have a characteristic degradation rate in the body. Bioresorbable scaffold acts as radio opaque coating material to evaluate the flaking out/dissipation of coated material changes occur in morphological properties at specific temperatures with qualities in specific time period at specific intervals. This study covers radio opaque coating over bioresorbable polymeric implant intended for use in cardiovascular treatments. The coating was observed at interval of days at a specified temperature of 37°C. In X-ray film, the radio opaque coating of 50% TIBA on bioresorbable scaffold revealed excellent radiopacity and clear morphology. The development of new class of radio-opaque polymer i.e. biocompatible polymers with the capability of absorbing x-rays. In many clinical applications, it is highly desirable that an implant can be visualized via routine x-ray fluoroscopy. This allows the physician to monitor location and for implants in a non-invasive manner.

Abstract: Locally advanced breast cancer, including Tumor-Node-Metastasis (TNM) stage T4, is the most frequently diagnosed cancer in Burkina Faso. Breast imaging is essential in the initial assessment and evaluation of the response of breast cancers under neoadjuvant chemotherapy (NAC). A therapeutic challenge is posed by the poverty of the population, aiming to rationalise paraclinical explorations, particularly medical imaging. We conducted this study to discuss relevant imaging strategies for the evaluation of tumour response in advanced breast cancer during neoadjuvant chemotherapy in our context of resource-limited countries. It was a cross-sectional descriptive study based on the medical records of patients followed up in the oncology department of the Yalgado Ouédraogo University Hospital. All patients treated for T4 non-metastatic breast cancer and who received at least one course of neoadjuvant chemotherapy were included. The study variables were the socio-demographic characteristics of the patients, the initial evaluation (clinical, radiological, anatomopathological); the mid-term and end-of-treatment evaluation of the ANC (clinical, radiological). T4 patients accounted for 74.28% of non-metastatic cancers diagnosed during the study period. The average age was 46 years. There were 96.15% of non-specific invasive carcinomas. Inflammatory type cancers accounted for 66.67% of cases. Lymph node involvement was present in 89.74%. All patients were classified as stage IIIB according to the UICC (Union for International Cancer Control). Initial, mid-term and end-of-treatment clinical assessments of the tumour were performed in 65.38%, 85.5% and 82.98% of cases respectively. Ultrasound was performed only at the initial stage in 51.28% of cases. CT scans were performed in all these evaluations but did not mention tumour size. The tumour response rate was determined empirically. CT would allow, at the same time as the extension assessment, to perform a loco-regional assessment of the breast tumour in the absence of other dedicated breast imaging.

Abstract: Background. Medical imaging consists of a variety of exploration techniques, the modalities of which are often not well known to prescribers. Prescribing these exams must meet certain criteria to ensure the safety of patient care. The objective of this study was to study the knowledge of medical doctoral students on the criteria for prescribing medical imaging exams. Materials and methods. This was a cross-sectional study with a prospective focus, conducted from 1 June 2020 to 31 August 2020 in university hospitals in the city of Ouagadougou. Were included randomly and exhaustively, with 386 medical doctoral students agreeing to respond to the questionnaire. The variables covered socio-demographic items, the type and frequency of prescription of imaging examinations, knowledge of the compliance criteria for medical imaging applications, biophysical principles and countermeasures indications of medical imaging examinations. Results. The sex ratio was 1.88. All doctoral students prescribed medical imaging exams. Standard radiography and ultrasound were the most prescribed examinations in 60.9% and 26.7% of cases. The least known compliance criteria were the requesting service and the purpose of the review in 9% and 11% of cases, respectively. Knowledge of the biophysical principles of medical imaging examinations, modalities using ionizing radiation were well known in 21.24% and 27.46% of cases. Contraindications for prescribing standard radiography, computed tomography and magnetic resonance imaging were known in 5.69%, 4.4% and 2.84% of cases. Conclusion. Medical doctoral students prescribe medical imaging exams with little knowledge of biophysical principles, modalities using ionizing radiation and contraindications related to the use of these techniques. Thinking needs to be done to improve their level of knowledge to ensure a reasoned prescription of imaging exams.
