Background: Angina is a common paediatric condition. It has certain peculiarities in children, particularly with regard to the frequency of bacterial germs and the use of diagnostic tests. The aim of this study was to determine the place of the rapid diagnostic test in the management of group A beta-hemolytic streptococcal angina in children in the paediatric ward at Donka National Hospital. Methods: This was a prospective descriptive study lasting 6 months from 1st February to 31st July 2019 concerning children aged between 3 and 15 years old who were diagnosed with angina. Epidemiological, clinical, para-clinical and therapeutic variables were studied. Results: Out of 1494 registered children, we collected 116 cases of angina (7.76%). Out of 52 patients who benefited from the rapid diagnostic test, we recorded 13 cases of angina due to group A beta-hemolytic strptococcus. The male sex was the most dominant with 31 cases (59.69%) and a G/F sex ratio of 1.47. The age group most affected was between 3 and 5 years old (50%). The average age of ou

Urban and peri-urban forests and trees play an important role by providing ecosystem services. Vegetation in sacred and cult places is among the useful forests and trees, but their characteristics are not well-documented. It’s necessary to assess the potential of biodiversity conservation in sacred and cult places. This research aimed to enhance knowledge of the woody diversity in cult places in Ziguinchor. To achieve this, woody vegetation surveys were conducted to determine floristic composition and, diversity and structural parameters of woody vegetation. A total of 89 species belonging to 71 genera and 33 families were recorded, Fabaceae and Moraceae dominated in cemeteries and parishes, while Arecaceae and Euphorbiaceae were prevalent in mosques. Tree diversity varied according to cult places. Parishes recorded significatively higher diversity (2.2 ± 0.18) than cemeteries (1.59 ± 0.13) and mosques (1.07 ± 0.36). Cult places inflenced significatly the structural parameters. Tree density was higher in cemeteries (482.26 ± 302.71 indiv/ha) compared to parishes (197.61 ± 67.14 indiv/ha) and mosques (32.34 ± 4.89 indiv/ha). Mosques were characterized by higher canopy cover (25.43 ± 11.65 m2/ha), larger (83.72 ± 20.09 cm) and taller (16.28 ± 1.28 m) trees. Natural regeneration was also strongest in cemeteries (91.69% ± 3.715%), followed by parishes (62.22% ± 8.56%) and mosques (38.82% ± 14.5%). The cult places play an important ecological role in biodiversity conservation in urban and peri-urban areas.

Introduction: Vitamin D plays a key role in phosphocalcic metabolism, in normal functioning of the immune system and in the prevention of certain forms of cancer. Systematic vitamin D supplementation has been implemented in most Western countries, which has drastically reduced the prevalence of rickets. In Senegal, a country with enough sunshine, no large-scale data exists on vitamin D deficiency in children. In addition, there are no guidelines from the Ministry of Health and Social Action (MoHSA) on vitamin D supplementation. Our objective was to determine the prevalence of vitamin D deficiency in children aged 6 to 59 months and to analyze the factors associated with it at the Institute of Social Pediatrics in Pikine-Guédiawaye, a suburb of Dakar. Patients and Methods: This was a prospective, descriptive and analytical cross-sectional study over a 3-month period (from January to March 2024) at the Institute of Social Pediatric (IPS) of Pikine-Guédiawaye. The study population consisted of all children aged 6 to 59 months free from any acute or chronic pathology, whose parents had agreed to answer the questionnaires after having consented and signed the consent and children who had had a sample taken for vitamin D dosage. Results: We included 102 children, 35 of whom had vitamin D deficiency, i.e. a prevalence of 34.31% with a slight male predominance (sex ratio 1.05). Infants aged 13 - 24 months were more affected (41.67%), but the difference was not statistically significant (p-value = 0.385). Patients with acute malnutrition had a significantly higher prevalence of vitamin D deficiency (54.17% of cases versus 28.38%) in those without acute malnutrition (p = 0.02). On the other hand, chronic malnutrition, underweight and diversification foods were not significantly associated with vitamin D deficiency (p of 0.60, 0.42 and 0.09 respectively). Conclusion: Vitamin deficiency affects one-third of apparently healthy children under 5 and this deficiency has no signific

Introduction: Temporomandibular joint ankylosis (TMJA) is a fusion of joint surfaces by fibrous or bone tissue and the resulting limitation of mouth opening. The objectives of this study were to determine the frequency of TMJA, describe the clinical aspects and assess management. Materials and Method: It was a retrospective study that was carried out in the Department of Odontostomatology and Maxillofacial Surgery of Donka National Hospital for a period of 5 years (January 2016 to December 2020). Included were all records of inpatients and managed cases of TMJA during the study period. Socio-demographic, clinical and therapeutic variables were analyzed. Results: During the study 13 TMJA cases were collected with the frequency of 0.47%. The age group 1 - 9 was the most affected (61.54%) with extremes of 4 and 28 years. Men were the most concerned (53.87%). Restriction of mouth opening was the main reason for consultation (69.23%). The etiologies of ankylosis were dominated by infection including cellulitis of dental origin (53.85%) followed by facial trauma (30.77%). Arthroplasty was the most commonly used technique (73%), two cases of recurrence were noted (15.38%). Conclusion: TMJA affects mainly children and the etiology is dominated by cellulite of dental origin hence the interest of sensitization of the population for early management of oral diseases.

The objective of this study is to analyze the dendrochronological potential of two Sahelian species (B. senegalensis and S. birrea) and to evaluate the relationships between their growth rings and the climate. The study was conducted in 2016 in the Ferlo area of Senegal. The biological material consists of wood slices, taken from the trunks of these adult woody species at 0.30 m and 1.30 m from the ground after they have been felled. The technique used to examine the slices consists in identifying their rings, establishing their structures, inter-dating them and studying the relationship between the identified rings and climatic factors. The results showed that the species had thin, clear, highly visible and sharp rings. The limit of growth is marked by a line of parenchyma. Intradatation series carried out on the chronologies made it possible to estimate the ages of the individuals, which vary from 10 to 38 years for B. senegalensis and from 29 to 50 years for S. birrea. Their average growth rates are estimated at 0.906 mm/year and 0.89 mm/year respectively. The chronological sequences are 29 years (1987-2016) for B. senegalensis and 38 years (1964-2012) for S. birrea. The results revealed that there is no significant correlation between the growth chronologies of

Introduction: In Guinea, data on the acute kidney injury (AKI) of women in the obstetrical context is still limited. This study attempted to determine the prevalence and the clinical signs of obstetric AKI in Guinea. Patients and methods: The study population consisted of pregnant or postpartum women with AKI, whom we treated in this institute from August 2018 to January 2019. All had normal anterior renal function with serum creatinine clearance ≥ 120 μmol/L, and then suffered AKI. Patients characteristics were examined;maternal age, gestational weeks, AKI characteristics. Results: Of 2438 pregnant women admitted during the study period, 56 showed AKI. Antepartum and postpartum AKI accounted for approximately 80% and 17%, respectively. Regarding the maternal age, Conclusion: We here demonstrated peripartum AKI in Guinea, which findings may provide fundamental data to establish some strategy against this condition in this region.
