Introduction: Ametropias or refractive errors are pathologies commonly encountered in ophthalmology characterized by the projection on the retina of a blurry image. There are several types of ametropia and each of them has a specific means of correction. In the literature, numerous data have been reported on the issue through studies that were mostly carried out on infant populations. To better treat ametropia in a more formal way, it is important to know their general characteristics within a larger population, hence the present investigation, the aim of which is to carry out an epidemiological study of ametropia at the Kati University Hospital-BSS. Materials and Methods: The study was carried out at Kati University Hospital-BSS between January 1 and December 31, 2022 and included 663 ametropic patients of all ages. Results: During the study period, 663 cases of ametropia were diagnosed out of 1678 new consultations, representing an incidence of 39.51%. Patients aged between 21 and 40 years were more affected. Depending on the type, these ametropias were dominated by compound astigmatism with 68.75% followed by isolated hyperopia and isolated astigmatism. Visual fatigue was the most mentioned reason for consultation. The female gender was in the majority with 70.9%. Low ametropia (Discussion: The growing visual needs of young people, especially with new information and communication technologies, would push them to consult the ophthalmologist more, and therefore to want optical correction in the event of a refractive anomaly, which would partly explain their high frequency in this age group. Conclusion: It is important to know the general characteristics of ametropia in the general population in order to improve the quality of life of patients affected by it through efficient therapeutic solutions.

Introduction: Ocular inflammation is a frequently encountered entity in ophthalmology. Depending on the inflamed part of the eye, different forms of ocular inflammation are distinguished. The challenge for the clinician will be to differentiate a benign pathology from a serious pathology that threatens visual function and requires urgent management. The aim is to make an epidemiological analysis of inflammatory eye diseases at the CHU-BSS of Kati. Materials and Methods: The study was carried out at the CHU-BSS of Kati between January 1 and December 31, 2023 and involved 1159 patients with various inflammatory eye diseases. Results: During the study period, 1159 cases of ocular inflammation were diagnosed out of 2111 new consultations, i.e. an incidence of 54.90%. Patients aged between 0 and 20 years were more affected with 41%. Women were more affected with 63.7%. The predominant symptom was pruritus with 57.8%. The main pathologies diagnosed were dominated by allergic conjunctivitis, bacterial conjunctivitis, with respectively 57.9% and 23.4%. Discussion: The results obtained reflect the findings made in the current practice of ophthalmology. Indeed, inflammatory diseases of the ocular surface, generally benign, are more frequent than intraocular inflammations which can jeopardize the functional or even anatomical prognosis of the affected eye. Conclusion: Endoocular inflammations are less frequent. Despite the possibility of functional complications, a rigorous diagnosis and a well-conducted medical treatment overcome most inflammatory ocular diseases.

Introduction: Malnutrition is an important reason for consultation in Mali’s health facilities and remains a major public health problem. The aim of this study was to describe the epidemioclinical profile and associated factors with performance indicators of integrated management of severe acute malnutrition in children aged 06 to 59 months. Methodology: this was a cross-sectional study with retrospective data collection (January 2021 to December 2022). All children hospitalized for severe acute malnutrition in the pediatric department and whose medical records were usable were included. Data collected using a standardized questionnaire was analyzed with SPSS Version 20 software. Results: A total of 534 children were included. The 12 to 23 months age group (49.1%) and the female sex (53.18%) were the most affected. Fully vaccinated children by age represented 49.4%. The predominant form of malnutrition was marasmus (77.7%). Diarrhea/vomiting (30.3%), fever (18.4%) and cough (15.5%) were the main reasons for consultations. Cure, discontinuation and death rates were 78.5%, 2.1% and 9.2%, respectively. On univariate analysis, the factors statistically associated with performance indicators (cure, drop-out, death) were gastroenteritis (P-value Conclusion: This study reveals that the frequency of severe acute malnutrition remains high at the Kalaban Coro reference health center. Better prevention of illnesses such as malaria, gastroenteritis, and respiratory infections, as well as timely referral, could help facilitate its management.

Open Journal of Ophthalmology 2022年第2期12卷 152-157页

作者： Nouhoum Guirou Sory Ibrahim Bamanta Nganga Ngabou Charles Gerauld Freddy Ali Konipo Abdoulaye Napo Modibo Sissoko Seydou Bakayoko Japhet Théra Fatoumata Sylla lamine traoré Institut d’Ophtalmologie Tropicale d’Afrique Centre Hospitalier Universitaire Université des Sciences des Techniques et des Technologies de Bamako Bamako Mali Centre Hospitalier Universitaire de Brazzaville Brazzaville Democratic Republic of the Congo

Aim: To analyze the clinical characteristics and the surgical outcomes of external dacryocystorhinostomy (DCR) in patients with nasolacrimal duct obstruction (NLDO). Methods: We retrospectively reviewed the clinical record of 62 patients who underwent external DCR for NLDO between November 2015 and November 2019 at CHU-IOTA in Mali. The preoperative clinical findings and the postoperative outcomes after a minimum follow up of 3 months were analyzed. Results: epiphora, discharges and canthal swelling were main symptoms of the 62 patients (68% women, 32% men), with the mean age of 47 years (10 - 76). Among them, 36 had chronic dacryocystitis, 12 had a traumatic NLDO and 8 followed a septal deviation. The majority (77%) were operated on under local anesthesia with sedation. Bicanalicular intubation was performed in 29% of patients. After postoperative follow up of at least 3 months, only 8 patients had persistent watering, thus a subjective functional success of 87%. Conclusion: In the nasolacrimal duct obstruction, most often secondary to chronic dacryocystitis, external dacryocystorhinostomy remains a technique of choice with very good success.

Introduction: The authors wanted to study the prevalence of ocular trauma in the ophthalmology unit of the CSREF of Kati. Patients and method: This is a retrospective study, covering the period from January to December 2015, carried out in the ophthalmology unit of the CSREF in Kati. Results: The sample consisted of 568 patients, or 6.82% of ophthalmological consultations. Children aged 0 to 14 years accounted for 154 (27.11%) of the trauma cases. Bruises constitute the main circumstance (58.1%) of eye trauma, followed by domestic accidents (15.6%). Closed globe ocular trauma was the main type of trauma (61.6%), followed by ocular adnexal trauma (30.1%) and open globe trauma (8.3%) in which the penetrating wound was the lesion, the least common (2.6%) but the most serious. Medical treatment was the most used therapeutic modality in 82.4% of cases, followed by surgery with 17.6% of cases. The evolution of the lesions after treatment was favorable in 85.6% of cases and unfavorable in 14.4% of cases. Complications were observed in 5.8% of cases and sequelae in 8.6% of cases. Conclusion: Ocular trauma constitutes an important reason for ophthalmological consultation at the CSREF of Kati. The severity of some of these lesions requires frequent recourse to surgery. The complexity of the treatment should encourage us to favor preventive measures.

Summary: Optic nerve tumors are rare tumors, representing 3% - 5% of intracranial tumors developing mainly along the optic nerve and/or the chiasm. Optic nerve meningiomas are histologically benign tumors whose severity is linked to diagnostic and especially therapeutic difficulties. The Optic nerve meningioma is the second leading cause of optic nerve tumor after glioma. Observation: We report the case of a 49-year-old woman from South Asia, who consults an ophthalmology department for progressive visual loss in her right eye for about a year with her glasses and would like to renew her optical correction. Having no particular medical history apart from left unilateral blindness is known for approximately 15 years. Magnetic Resonance Imaging (IRM) cerebral found a tissue mass with a clear outline and polylobules on the left temporo-peduncular. Through this case, we describe the circumstances of discovery of the disease, the clinical characteristics, as well as our diagnostic approach. Conclusion: In the majority of cases, these are benign tumours, the circumstances of which are discovered in multiple ways. A mostly unilateral and non-improvable loss of visual acuity must attract our attention. Renewing glasses may be the reason for discovering the disease. Today Magnetic Resonance Imaging (IRM) remains an important and capital examination for the diagnosis and monitoring of this pathology.

Journal of Minerals and Materials Characterization and Engineering 2018年第3期6卷 257-270页

作者： Yeri Dah-traoré lamine Zerbo Mohamed Seynou Raguilnaba Ouedraogo Laboratory of Molecular and Materials Chemistry Chemistry Department University Ouaga 1 Professor Joseph KI-ZERBO Ouagadougou Burkina Faso

This paper deals with the elaboration of porous ceramic pots with raw clay materials and rice husks for water filtration. The basic raw clays have been mixed with rice husks at different ratio 10% and 15% weight (wt) and sintering at 1200°C, 1300°C and 1400°C for 30 minutes. The elaborated pots have been tested for their densification properties and filtration flow. The mineralogy and microstructure of pot have been also studied to explain the different results. The pot with 10% wt rice husks and sintering at 1300°C during 30 minutes presents a sufficient porosity and mechanical strength to be used for water filtration.

We carried out a retrospective and descriptive study in the Medicine and Endocrinology service of the Mali Hospital from January 2015 to December 2018. Nine cases of anomalies in sexual differentiation were referred for pubertal delay, growth retardation, gynecomastia, micropenis or infertility. Outcomes: The average age was 14 years;5 patients were declared female at birth;2 were married without children;7 patients came from the region of Kayes;8 patients consulted for pubertal delay;1 patient presented with association of a blind vagina and 2 bilateral inguinal gonads. 3 of 4 patients declared male at birth had a micropenis;2 patients had gynecomastia with a history of hypospadias. Ultrasound and biological data showed a clinical-hormonal picture of hypergonadotropic hypogonadism in 6 patients, 1 case of hypogonadotropic hypogonadism with hypercorticism and 2 cases with normal gonadotropic axis;two cases of azoospermia. Karyotypic analysis showed: 3 cases of SK, 2 cases of Klinefelter Syndrome, 2 cases of Androgen Insensitivity Syndrome and 2 cases of male 46 XX syndrome including one with sry negative. Conclusion: The precise diagnosis of anomalies in sexual differentiation remains complicated in Mali, due to the inadequacy of the technical platform. Diagnosis must be made at an early stage to allow normal growth, puberty and satisfactory fertility. Taking charge of the medical treatment possibly associated with plastic surgery could give good results.

Natural convection heat transfer in open or closed cavities takes place in different engineering areas. The hemispherical cavity is a part of basic geometries although it is not widely studied. The present paper reports the numerical study of natural convection in a closed hemispherical annulus delimited by two vertically eccentric hemispheres filled with Newtonian fluid (air in this case with Pr = 0.7) is conducted. The inner hemisphere is heated by a heat flux of constant density and the outer one is maintained isothermal. Based on the Boussinesq assumptions, the governing equations are numerically studied using unsteady natural convection formulated with vorticity and stream-function variables. These equations are written by using bispherical coordinates system and solved by using a finite difference method. The effect of the control parameters such as the Rayleigh number (103 ≤ Ra ≤ 106) or the eccentricity (e = ±0.2, ±0.5, 0) in the dynamic and thermal behaviours of the fluid is investigated.
