It, therefore constitutes a therapeutic target. Its morphology is extremely variable. Objective: it consisted on determining the morphological variations of the left auricle as well as their interest in the prevention of thrombi in the Senegalese. Material and Method: This study was conducted by dissecting 36 fresh hearts from Senegalese anatomical subjects with a sampling of the left atrial appendage, including specimens with normal morphological appearance. Their morphology was studied using the fresh and frozen plaster molding method. The data obtained were analyzed statistically. Results: the average age of the subjects was 33 years, with a sex ratio of 1.06, the cauliflower shape was dominant with 57% of cases and the cactus shape (4%) was less frequent. The cauliflower shape presented a clear angulation compared to the others without statistically significant differences according to age. Conclusion: This work showed a great morphological variability of the left atrial appendage. It can provide an update on the specificity of Senegalese. Taking these variations into account is important in the safe management of hemodynamic conditions and the improvement of the management of recurrent strokes.展开更多

It plays a major role in the stability and realization of axial rotation movements of the thoraco-lumbar spine. Its atrophy by fatty degeneration would be at the origin of the occurrence of chronic low back pain which constitutes a public health problem in Senegal. Taking into account its anatomy is essential for the etiopathogenic analysis and the treatment of low back pain. The purpose of our work was to investigate the impact of multifidus muscle morphometry on the anatomy-clinical evolution of low back pain. Material and method: this was a prospective study over a period of 30 months from November 2019 to May 2022. It involved 100 patients seen in the neurology department of Fann Hospital for chronic low back pain and who had already had a scanner falling within the criteria for low back pain. We used 3D Slicer, SPSS 20, Excel 2016 software to model and analyze the morphometric data of the multifidus muscle after physiotherapy and control lumbar scans. Results: The sex ratio was 2.23. The average age of the patients was 45 ± 7 years. On the initial CT scan, according to the Hadar classification, we noted a predominance of grade 2 with 56% in L5/S1, followed by grade 1 with 32% and grade 3 with 14%. In L4/L5, the majority of patients, 67%, had grade 1. A conflicting circumferential disc bulge with the roots predominating in L5/S1 was present in 94% of men (p-value = 0.02). Before physiotherapy, the average volume of the multifidus was 193 mm<sup>3</sup> ± 39, after physiotherapy it was 203 mm<sup>3</sup> ± 42 with a progression rate of 5.2%. Clinically, severe type pain had regressed from 86% before physiotherapy to 0% after physiotherapy (p-value = 0.03). Conclusion: Taking into account the morphometry of the multifidus is an essential element in the management of chronic low back pain.展开更多

Methodology: We conducted a non-exhaustive preliminary study over a period of three months from the first of January to 31 March 2010 at four major hospitals in Dakar at the time. Results: Two hundred and eighty-nine cases had been identified: 44% of men (n = 127) and 56% of women (n = 162) with a sex ratio of 0.8. The ages ranged from 20 to 90 years with an average of 50 years. The main diagnostic mode was essentially histological, with 76% of cases (n = 219). The most frequent locations were: ORL (ENT meaning Ear, Nose and Throat) with 25% of cases, liver 7% and bronchopulmonary 4.5% of cases. In men, liver cancer was the most common location and women for cervical cancer with 16%. Squamous cell carcinoma was the most common histological type with 68% of cases followed by adenocarcinoma with 22% of cases. Thirty-eight percent of patients were classified as stage III and IV. A quarter of our patients had received palliative treatment. In contrast, 15 (15%) had received chemotherapy and 4% had received radiotherapy. Data collection was satisfactory. Conclusion: Cancer is a reality in Senegal but it remains underdiagnosed. The materials made it possible to make the cancer registry effective throughout the country.展开更多

In context of breast cancer increase in Senegal, we have carried out breast morphology in female subjects of the Sahelian type in order to contribute to the development of a morphological database for reconstruction, reduction or breast augmentation. It was a prospective study on 118 female subjects received at Cancer Institute for screening. They were divided into two groups (age ≤ 40 years and age?> 40 years). Subjects’?morphometric variables were collected in anatomical position and correlated with age, parity, obesity and genital activity using. Fifty six subjects (47.5%) were over 40 years of age. There were 40 multiparous (33.9%). Fifteen subjects (12.7%) and six subjects (5%) were obese and morbidly obese, respectively. Subjects in genital activity were 34 (29%). The overall average size of the areola was 4.3 ± 1.5 cm. The nipple was low located with an average of 7.2 ± 3.5 cm. The diameters mentioned above increased significantly with age and body mass index, for p-values ?0.05, with the exception of the vertical diameter. Breast diameters were greater in postmenopausal women. Morphometry of Sahelian-type women’s breast is strongly influenced by socio-demographic data, hence the need to take it into account during reconstruction, reduction or breast augmentation surgeries in Senegal.展开更多
