Aim: To describe the two-dimensional elastographic profile according to the Shearwave (2D-SWE) technique in patients with chronic liver disease in Lom. Materials and method: Cross-sectional, descriptive study conducted over seven month at the Autel dElie Clinic in Lom, from January to August 2022, on adult patients with chronic liver disease who underwent abdominal ultrasound coupled with two-dimensional elastography. Results: The sample size was 54 patients. The mean age of the patients was 33 12 years, with extremes of 18 and 66 years. Patients aged 30 years or less accounted for 48.1% (n = 26). All patients (n = 54) had at least one transaminase assay with a mean of 69.3 78.3 IU/l (AST) and 59.3 82.8 IU/l (ALT). There was no statistically significant association between the biological parameters and the presence of fibrosis. Viral liver disease was the main cause, accounting for 81.5% (n = 44) of cases, with no significant association with the degree of fibrosis. Ultrasound revealed a dysmorphic liver (57.4%;n = 31) and portal hypertension (18.5%, n = 10). Fibrosis stages F1, F2 and F4 accounted for (48.1%, n = 26), (24.1%, n = 13) and (13%, n = 7) of cases respectively. Liver dysmorphia was significantly associated with the presence of fibrosis (p = 0.012) and portal hypertension was significantly associated with the degree of fibrosis (p = 0.0063). Conclusion: Assessment of liver fibrosis in patients with chronic liver disease using 2D-SWE elastography is essential for patient follow-up.

Open Journal of Radiology 2024年第2期14卷 55-63页

作者： Massaga Dagbé bidamin n’timon Ousmane Aminata Bah Pihou Gbandé Komi Awobanou Koku Adambounou Masamaesso Tchaou Abdoulatif Amadou Lantam Sonhaye Lama Kegdigoma Agoda-koussema Komlanvi Victor Adjénou Radiology Department Kara University Hospital Kara Togo Armed Forces Reference Imaging Center (CIRA) Conakry Guinea Radiology Department Sokod Regional Hospital Sokod Togo Radiology Department Lom University Hospital Lom Togo Radiation Protection/Telemedicine Department Lom University Hospital Lom Togo Radiology Department Kara Regional Hospital Kara Togo

Aim: Lead aprons are used to protect against scattered radiation from the patient during interventional procedures and certain special conventional radiological examinations. Given the importance of the role lead aprons are supposed to play in radiation protection, we propose to assess their conformity in medical imaging departments in public and religious hospitals in Togo. Materials and method: A multi-centre survey conducted from 26 november to 06 December 2021 in the radiology departments of public and religious health facilities in Togo. All aprons in use were included. The evaluation criteria were physical (visual), quantitative (radiographic) and qualitative (dosimetric). Results: We had registred 43 aprons among wich 27 (62.79%) leaded aprons were labelled non-compliant and 16 (37.21%) were labelled compliant. Of the aprons judged to be non-compliant, 70.37% were more than 10 years old and 96.30% showed defects on the radiographic images. The most common defects were vampire marks (18.64%), multiple folds (16.96%), cracks (16.96%), multiple cracks (15.25%), tears (8.47%), absence of lead (5.08%), holes (3.39%) and lead corrosion (1.69%). Defective aprons (62.96%) had at least two defects. The defects were of thoraco-abdomino-pelvic (74.07%), thoracic (14.82%) and abdomino-pelvic (11.11%) topography. For indirect exposure at 50 and 70 kilovolts, all the aprons had an attenuation factor greater than 90%. After dosimetric measurement, 13.95% of aprons had attenuation factors below 90% for indirect exposure at 100 kilovolts. Conclusion: The compliance of the leaded decks is trifactorial (physical, radiographic and dosimetric). However, there is no significant difference in X-ray attenuation capacity between defective and normal decks.

作者： Abdoulatif Amadou Lantam Sonhaye Kossivi Apetse Komlan Amoussou Mazamaesso Tchaou bidamin n’timon Kahabilou Atsa Agbangba Gani Watara Komlavi Adjenou Department of Radiology Campus University Teaching Hospital of Lomé Lomé Togo Department of neurology Campus University Teaching Hospital of Lomé Lomé Togo Department of Radiology Sylvanus Olympio University Teaching Hospital of Lomé Lomé Togo Department of Radiology University Teaching Hospital of Kara Kara Togo

Studies on the canal dimensions of the cervical spinal are rare in Africa. The aim of this study is to provide normal values of the cervical spinal canal and spinal cord dimensions of adult people in Togo. It was about a twelve-year prospective study conducted in the main Hospitals of Campus Teaching Hospital. This study involved people of more than 18 years who neither presented any clinical sign nor rachis defect. The distances measured were antero-posterior 1 (APD1) and inter-pedicular (IPD) of the cervical spinal canal, the antero-posterior 2 (APD2) and the transverse (TD) diameters of the cervical spinal cord, followed with APD2/APD1 (R1) and TD/IPD (R2) research reports. The mean age was 38 +/- 9.34 years old. The average of APD1 of the cervical spinal canal stood at 15.41 ± 0.55 mm, with a minimum of 10.48 ± 0.57 mm and a maximum of 25.00 ± 2.60 mm. The IPD average stood at 23.27 ± 1.67 mm with a minimal average of 13.68 ± 1.46 mm and a maximal average of 33.68 ± 1.46 mm. The average of DAP2 was 11.66 ± 0.66 mm, with a minimum of 10.7 ± 0.66 mm and a maximum of 12.77 ± 0.66 mm. The DT average stood at 15.55 ± 1.54 mm, with a minimal average of 14.03 ± 2.43 mm and a maximal average of 17.63 ± 1.82 mm. The ratio R1 (APD2/APD1) average was 0.80 ± 0.04, with a minimum of 0.76 ± 0.06 and a maximum of 0.85 ± 0.07. The ratio R2 (TD/IPD) average stood at 0.69 ± 0.14, with a minimum of 0.5 ± 0.12 and a maximum of 0.84 ± 0.08. The cervical spinal canal and the cervical spinal cord diameters in Togo are not significantly different from those described above.

引用

Open Journal of Radiology 2017年第2期7卷 85-94页

作者： Abdoulatif Amadou Mawuena Yao Dansou Lantam Sonhaye Komlan Amoussou Mazamaesso Tchaou bidamin n’timon Kahabilou Atsa Agbangba Gani Watara Komlavi Adjenou Department of Radiology Campus University Hospital of Lomé Lomé Togo Department of Radiology Sylvanus Olympio University Hospital of Lomé Lomé Togo Department of Radiology University Hospital of Kara Kara Togo

Objective: Determine the frequency of the sinonasal mechanical anatomic variants by CT Scan. Patients and method: Six-month retrospective study concerning sinus CT scans in the registers of Teaching Hospitals’ Imaging Services of Lomé and Kara (TOGO). It involves patients without distinction of sex, of over 15 years without anomaly that can lead to a modification of the normal anatomical configuration of the paranasal sinuses’ cavities. The analysis has been made by only one radiologist. Results: The frequency of mechanical sinonasal anatomic variants stood at 91.87%. The narrowing of the middle nasal turbinate was the variant mostly observed (55.03%), dominated by the deviation of the nasal septum whose frequency was 25.48%. The narrowing of the infundibulum represented 10.80% of population. They were more represented by the Haller cell which displayed a frequency of 3.60%. The variants venturing to narrow the upper nasal turbinate, represented only by extra turbinates, involved 1.02% of the population. The other variants of mechanical sinonasal anatomic variants represented 25.02%. They were dominated by the maxillary sinus septa (11.2%). Our study showed a feminine predominance which is statistically important for Haller cells (p = 0.037) and the ethmoidbulla hypertrophy (p = 0.0036). Conclusion: The anatomic variants of mechanical sinonasal are very frequent in Togo.

Studies of male breast cancer are rare in Africa. In Togo in particular, no work has focused on the epidemiological, mammo-echographic, pathological, therapeutic or prognostic aspects of male breast cancer. The aim of this study is to report cases of male breast cancer in Togo by describing the main epidemiological, mammo-echographic and pathological aspects. This was a retrospective, descriptive and analytical study of 10 cases of male patients presenting with breast cancer confirmed by the pathologic examination on the echo-guided samples over a period of 6 years in University Teaching Hospital in Lomé. A total of ten patients were retained. The mean age of patients was 55 years with extremes of 39 years and 65 years. All patients had a palpable breast mass. The lesions were classified in 60% American College of Radiology (ACR) 5 and 40% ACR 4. The axillary lymph node invasion rate was 40%. Infiltrating ductal carcinoma was the histologic type diagnosed in all patients. Any breast mass in an elderly male subject is suspected with high predictive value. Mammography ultrasound plays an important role in the diagnosis alongside pathology.

We report the case of a 50-year-old patient, who was explored in mammography, ultrasound and CT for a large painful mass of the right breast that had been evolving for 30 years and gradually increasing in size. There was a typical “sausage slice” appearance with clear center macrocalcifications on the mammogram;an aspect of “breast in the breast” on ultrasound. The scanner had made it possible to specify the dimensions of the mass, which measured 21.4 cm in height;18.6 cm wide and 9.5 cm thick. Histology after exeresis noted the adenolipofibromatous nature of the mass.

引用

Open Journal of Radiology 2017年第1期7卷 1-8页

作者： Mazamaesso Tchaou Haréfétéguéna Bissa Plaodesina Essobozou Pegbessou Abdoulatif Amadou bidamin n’timon Mawuena Dansou Abdoul-Razakou Adam Lantam Sonhaye Lama-Kegdigoma Agoda-Koussema Komlan Adjenou Department of Radiology Sylvanus Olympio Teaching Hospital of Lomé Lomé Togo Department of Oral and Maxillofacial Surgery Sylvanus Olympio Teaching Hospital of Lomé Lomé Togo Department of EnT and neck Surgery Sylvanus Olympio Teaching Hospital of Lomé Lomé Togo Department of Radiology Kara Teaching Hospital Lomé Togo

Background: In dental-maxillofacial imaging, 3D sectional imaging progressively replaces conventional 2D imaging in developed countries. They are based specially on Computed tomography (CT-Scan), with the Dentascan application and cone beam computed tomography (CBCT). In developing countries those technics are newly introduced. Aim: This study aimed at studying the knowledge and practices of dentist and oral and maxillofacial surgeons on sectional imaging such as Dentascan and Cone Beam Computed Tomography (CBCT). Materials and Methods: We conducted an anonymous survey among dentists and oral maxillofacial surgeons in Togo over one month. Results: The response rate was 78.79% (27/33). They were mainly male sex (sex ratio of 2.25 men for one woman). They were aged between 27 and 71 years old with an average of 49.69 years old. The majority (61.54%) had a professional experience over 20 years. The majority of respondents (65.38%) believed their level of knowledge about dental x-Ray was poor. Half of them (50%) confirmed that they had never asked for a Dentascan, and 15.38% asked from time to time for it and only two (7.69%) asked often for this test. 96.15% confirm they have no knowledge of the Dentascan. Regarding the CBCT, 84.62% didn’t ask for it because this technique did not exist in Togo before. 69.20% of respondents confessed to be interested in continuing training on sectional imaging. Conclusion: This study shows that sectional imaging is very little used by oral and dental practitioners in Togo because of the ignorance of the new techniques and the absence of the CBCT. It is therefore necessary to promote the teaching of the new technique of sectional imaging in the training syllabus of oral and dental specialists and to initiate continuing medical training.

The objective of this study was to assess knowledge and attitudes about breast cancer screening among students in the Faculty of Health Sciences at the University of Lomé. Methods: This was a prospective descriptive transversal study conducted among students enrolled in the Faculty of Health Sciences (FSS) of the University of Lomé (UL) in the 2019 school year account 2020. The purpose of this study was to assess the knowledge and attitudes of medical students about breast cancer screening. Results: In total, the questionnaire was completed by 934 students, for a response rate of 57.1%. The most frequently mentioned risk factors were the presence of a family history of breast cancer (n = 799, 85.55%) and the use of oral or injectable contraceptives (n = 606, 64.88%). There is a statistically significant link between the participants’ knowledge of the self-examination and clinical examination of the breasts and certain socio-demographic characteristics, namely age (OR = 0.2, 95% CI [0.11n> - 0.75], p-value 0.0001), the level of study (OR = 1.5, 95% CI [0.55 - 2.46], p-value = 0.0054), the follow-up of a course on breast cancer (OR = 2.63, 95% CI [0.32n style="font-family

Umbilical Artery Resistance Index in the Surveillance of Pregnancies at Risk of Fetal-Maternal Hemodynamic Disorders in Lomé(Togo)

引用

Open Journal of Radiology 2018年第3期8卷 159-166页

作者： Sonhaye Lantam Kolou Bérésa Boube Abarchi Habibou Bah Ousmane Aminata Amadou Abdoulatif Gbande Pihou Assih Kouméabalo Tchaou Mazamaesso ntimon bidamin Adjenou Komlanvi Radiology Department of Campus Teaching Hospital of Lomé Lomé Togo Radiology Department of Sylvanus Olympio Teaching Hospital of Lomé Lomé Togo Radiology Department of Kara Teaching Hospital of Kara Lomé Togo

Objective: Evaluate the role of umbilical artery Doppler ultrasound in the surveillance of pregnancies at risk of vascular disorders in Lomé. Study Method: The study was a cross-sectional analytical study carried out in the department of radiology of Campus teaching hospital over a period of 6 months. This study was based on the measurement of the resistance index of the umbilical artery in pregnant women presenting vascular risk and other pregnant women without vascular risk. The correlation between the pathological index and the at-risk pregnancies was assessed by the Odds Ratio as well as the correlation between the resistance index and the Apgar score at birth. Results: The resistance index was measured in 209 at-risk pregnant women and in 425 pregnant women without vascular risk. The average age of pregnant women was 26.31 years for “the at-risk pregnant” versus 25.38 years for the “pregnant-witnesses”. The association between the pathological resistance index (RI) and the gestational pathologies studied, had been positive and significant with an odds ratio of 1.57 for a 95% confidence interval of [1.07 - 2.20]. A pathological RI is a risk factor for the occurrence of a pathological Apgar score at birth because this association was positive and significant for “pregnant-cases” as for “pregnant-witnesses”. Conclusion: Measuring the index of resistance is not a common practice in our communities. However, it could be an important tool in the surveillance of at-risk pregnancies for diseases such as malaria, pre-eclampsia, and maternal anemia.
