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.

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.

The use of food additives in industrial production has the advantage of improving sensory properties, technological quality and extending the shelf life of foods. Among the most widely used additives are antioxidants, which prevent oxidation, browning and rancidity reactions in foods. However, the strong presence of these additives on the market is not without risks for human health, and should be controlled to guarantee food safety. Analysis of the risks associated with consumption of foods containing these additives requires, among other things, information on the frequency of use of these additives in various consumer products. The aim of this study is therefore to identify the antioxidants present in industrial food products distributed in Dakar. The methodology adopted consists of a qualitative analysis based on the identification of additives from food labels. Investigations were carried out in 9 stores, 4 superettes and 2 supermarkets located in different districts of Dakar. The results revealed the presence of 12 antioxidant additives, dominated by citric acid (53%) and ascorbic acid (29%). These studies have also highlighted the simultaneous use of several antioxidants in the same food product. Moreover, for some artificial antioxidants identified antioxydant such as BHA and BHT, health risks are associated with their consumption. The results of this study open up prospects for the development of information databases on food additives.

Protein is essential for the growth and maintenance of the body. They play a crucial role in different biological processes. This study focuses on comparing the protein contents of local rice grown in the Senegal River valley and rice imported from Asia. The objective is to evaluate the importance of the protein nutritional value of local rice compared to imported rice. Protein contents were determined using the Kjeldahl method. The results of the protein assays show that local rice varieties such as Sahel 108 and Sahel 134 grown in the Thilène basins had protein percentages comparable to those of imported rice. The protein percentages were 15.19% ± 0.91% for the Sahel 108 variety and 16.62% ± 0.01% for the Sahel 134 variety compared to 15.8% ± 0.01% on average for imported rice. Thus from the point of view of protein content, local rice has a nutritional value identical to that of imported rice which it can validly replace. It is important in Senegal to encourage local production, which would make it possible to reduce imports on the one hand and to make quality rice available to the local Senegalese market on the other. Sahel varieties with high protein contents deserve large-scale development to meet the country’s protein needs.

Background: This study aimed to describe the results of mammography done during breast cancer awareness campaigns in Lomé. Methods: This was a retrospective multicenter study which focused on the analysis of mammographic examinations, with or without breast ultrasound, carried out in three (3) clinics in Lomé over a period of five (5) years during the breast cancer awareness month (Pink October) campaigns. We included in our study women of all ages who underwent a mammography during the study period. Additional ultrasound was performed as needed in some women to better characterize a lesion. The parameters studied were socio-demographic data, and aspects of breast lesions. We classified the lesions in order of severity according to the BI-RADS classification. Results: During the study we counted one thousand and seventy-four (1074) women who underwent mammography examinations, corresponding to an average of 214.8 women per year. The median age of the women was 46 years. The most represented age group was 40 - 49, constituting 30% of cases. Mammography was performed on all women and ultrasound was performed on 51.3% of women. Lesions suspicious for malignancy (BI-RADS IV) and lesions highly suggestive of malignancy (BI-RADS V) represented 3.5% and 1.9% of cases respectively, amounting to a prevalence of 5.4%. They occurred more frequently from the age of 30 years with a statistically significant difference (p = 0.02). These lesions could be identified on mammograms as masses with irregular shapes and spiculated margins representing 16.1% and 9.7% of masses respectively. On ultrasound, these were solid masses with irregular and ill-defined borders, representing 25.2% and 5.2% of solid masses respectively. Lesions suspicious for malignancy were most often found in the UOQ (upper outer quadrant) in 70% of cases. Conclusion: Mammography screening for breast cancer remains a necessity in our comm

Contribution of Metabolic Imaging in the Exploration of Cognitive Disorders Related to COVID-19

引用

Advances in Molecular Imaging 2024年第1期13卷 1-5页

作者： Serigne Moussa Badiane amadou Barro Elhadji amadou Lamine Bathily Louis Augustin Diaga Diouf Biophysics and Nuclear Medicine Gaston Berger University Saint-Louis Senegal ENT Department Fann University Hospital Dakar Senegal Biophysics and Nuclear Medicine Cheikh Anta Diop University Dakar Senegal

On March 11, 2019, the WHO declared COVID-19 a pandemic disease. It is a respiratory tropism SARS COV 2 infection. In the emergency of the pandemic, in medical imaging, only computed tomography (CT) of the lungs was favored to assess lung lesions. In addition, many cases of post-COVID-19 cognitive disorders have been reported. As the curve dips and services restart correctly, other imaging techniques have been used to better explore the disease. The objective of this presentation is to illustrate the contribution of metabolic imaging in the exploration of post COVID-19 cognitive disorders and to discuss the pathophysiological mechanisms. Hypometabolism brain lesions are objective signs of functional impairment whose pathophysiological mechanism is not yet fully understood. Metabolic imaging with PET-SCAN is a suitable tool for exploring these disorders, both for the severity and extent of the lesions and for the topography of the brain damage.

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.

Open Journal of Geology 2024年第5期14卷 617-628页

This study focuses on exoscopic analyses of detrital zircon grains of Archean and Paleoproterozoic age, contained in the sediments from the Niamey Neoproterozoic sandstones (Niamey region), with a view to confirming the sediments sources already proposed (Kénéma-Man domain for Archean-age zircons and Baoulé Mossi domain for Paleoproterozoic-age zircons). Exoscopic analysis reveals that Archean zircon grains are more corroded, with rounded to sub-rounded shapes, while Paleoproterozoic zircon grains are less corroded and mostly angular in shape. The strong corrosion of Archean zircon grains, implying long-distance transport, is consistent with the remoteness of the Kenema-Man domain which are the source these sediments. The fact that the Paleoproterozoic zircon grains show little or no wear implies a proximal source of sediments, corresponding to the Baoulé Mossi domain.

Supernumerary urethra in boys is a very rare anatomical entity. Sagittal urethral duplications are classified into four groups: epispadias, hypospadias, fusiform and Y-shaped urethra. The most widely used classification is that of Effmann and Lebowitz, which describes 6 types, one of the rarest being the ‘Y’ subtype IIA2, which corresponds to a duplicated urethral path from the vesical neck to an ectopic perineal or anal outlet. We report here the case of a 4-year-old child presenting with subtype IIA2 with a perineal orifice and no other urinary disorders.

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.
