Objectives: To study the hospital frequency of lower extremity arterial disease and identify associated factors in diabetic patients at the Libreville University Hospital Center (CHUL). Materials and Methods: This was a cross-sectional study conducted from July 1, 2023, to January 31, 2024, in the endocrinology department of the CHUL. All patients with type 2 diabetes over the age of 18 admitted to this department, regardless of the reason for hospitalization, who provided informed consent, were included. Socio-demographic data and cardiovascular risk factors were recorded. Personal and family cardiovascular history and functional symptoms were investigated. The physical examination included measuring blood pressure, heart rate, and the ankle-brachial index in all patients. Results: A total of 219 patients were included, of whom 75 had lower extremity arterial disease, representing a prevalence of 34.24%. It was compensated in 28 cases (37.33%) and decompensated in 39 patients (52%). In eight cases (10.67%), there was critical chronic ischemia. Cardiovascular risk factors associated with diabetes were physical inactivity (89.5%), hypertension (55.25%), overweight (49.77%), obesity (22.84%), and smoking (10.04%). In multivariate analysis, only hypertension (OR = 2.09;95% CI: 1.05 - 4.17;p = 0.035) and LDL cholesterol (OR = 2.75;95% CI: 1.10 - 6.85;p = 0.03) were significantly associated with lower extremity arterial disease in diabetics at the University Hospital of Libreville. Conclusion: Lower extremity arterial disease is common in diabetic patients at the University Hospital of Libreville. It is often asymptomatic, thus requiring systematic screening.[-rId11-]展开更多

These deformations involve the size, shape, color, and vessels of the optic disc. Although often asymptomatic, these anomalies can impact the visual development of the child, underscoring the importance of a thorough fundus examination for early detection and appropriate medical follow-up. We present two cases of congenital optic disc anomalies in children, illustrating the diagnostic challenges and complexity of their management. Case 1: A 3-year-old girl presented with a white spot in her left eye present since birth. Uncorrected distance visual acuity was 2/10 in the right eye, while she could perceive hand movements at 2 meters with the left eye. Normal examination in the right eye showed leukocoria, microphthalmia, and a white mass at the center of the optic disc on fundus examination in the left eye. Ocular imaging, including ultrasound and optical coherence tomography (OCT), confirmed the diagnosis of persistent hyperplastic primary vitreous (PHPV) in its mixed form in the left eye. Management included prescribing full optical correction and functional rehabilitation, without resorting to surgery. The course was marked by persistent amblyopia leading to a poor prognosis. Case 2: A 7-year-old girl consulted for vision disturbance in her right eye. Visual acuity was finger counting at 2 meters in the right eye and 10/10 in the left eye. Anterior segment examination revealed no abnormalities in both eyes. However, fundus examination highlighted a large funnel-shaped excavation associated with central glial proliferation, wheel spoke vessels, and neuroretinal ring atrophy in the right eye. Optical coherence tomography (OCT) of the right eye confirmed the diagnosis of isolated unilateral Morning Glory syndrome. Management included full optical correction and orthoptic rehabilitation. The course was marked by the absence of ocular complication and maintenance of visual stability in the right eye. The prognosis seemed favorable. Conclusion: Congenital optic disc anomalies in children exhibit great clinical variability and require an individualized diagnostic and therapeutic approach.展开更多

This anatomical peculiarity is of growing interest due to its impact on vision and the therapeutic challenges it presents. Despite research advances, gaps persist, requiring thorough exploration to better understand this rare condition. We present the case of a young girl. Observation: A 7-year-old girl presented with persistent deterioration of vision in the right eye since birth. Visual acuity was counting fingers at 2 meters in the right eye and 10/10 in the left eye. Biomicroscopy was normal in both eyes, and fundus examination revealed a funnel-shaped excavation at the optic disc of the right eye, associated with central glial proliferation, thin blood vessels in a radial distribution, and atrophy of the neuroretinal rim. Additional tests confirmed the diagnosis of isolated unilateral Morning Glory Syndrome in the right eye. Combined treatment included appropriate optical correction and functional rehabilitation. Regular ophthalmological follow-up over a one-year period was established to monitor visual acuity evolution, optic disc stability, and detect any potential complications. The reserved prognosis was marked by the absence of ocular complications and maintenance of initial visual acuity in the right eye. Conclusion: The positive response to management underscores the importance of an integrated approach, early diagnosis, therapeutic adherence, and personalized strategies.展开更多

This case report describes the observation of a 3-year-old child with melanoderma, presenting with a white spot in the left eye since birth. Observation: Uncorrected distance visual acuity was 2/10 in the right eye and hand movements were perceived at 2 meters in the left eye. Examination of the anterior segment in the left eye revealed leukocoria and microphthalmia. The fundus examination was normal in the right eye but revealed a white mass extending from the center of the optic disc towards the temporal region in the left eye. Ocular imaging, including ocular ultrasound and optical coherence tomography, confirmed the diagnosis of PHVP, illustrated by a residual white mass at the center of the optic disc in the left eye. Conclusion: PHVP should be considered in the presence of leukocoria in a child, with urgent exclusion of retinoblastoma. This observation underscores the importance of early diagnosis for appropriate management. .展开更多

In Gabon, 10% of the population is affected by this condition, highlighting the need to actively understand and manage it. Ocular complications of diabetes, including diabetic retinopathy, glaucoma, and cataracts, have a devastating impact on patients quality of life and represent a crucial issue for healthcare systems. Methodology: This study conducted in Libreville from February 9, 2022, to April 15, 2022, was cross-sectional, longitudinal, and descriptive, with prospective data collection. Participants were diabetic patients regularly followed in the endocrinology department of CHUL, who were referred for a comprehensive ophthalmological examination at CHUO. Sampling was exhaustive, with strict inclusion criteria aimed at ensuring the representativeness of the study population. Results: The mean age of participants was 57.5 ± 13.2 years with a male-to-female ratio of 0.8. Personal histories were dominated by hypertension, while family histories were dominated by diabetes. Ocular complications of diabetes included refractive disorders (78.9%), cataracts (31.7%), glaucoma (78.9%), and diabetic retinopathy (13.7%). These ocular complications had a significant impact on participants’ quality of life, leading to impaired vision (78.9%), difficulties in carrying out daily activities (62.2%), the need for caregiver assistance (50.3%), high levels of stress and anxiety (68.9%), regular medication intake (71.4%), adherence to a specific diet (55.9%), and frequent blood glucose monitoring (74.5%). Conclusion: This study highlights the major impact of diabetic ocular complications on patients’ quality of life.展开更多

Among its complications, diabetic retinopathy stands out as the leading cause of blindness in industrialized countries. Physical activity is now recognized as a cornerstone of diabetes management, and its impact on diabetic retinopathy is of growing interest. Observation: Mr. A.E, a 54-year-old man, presents with progressive deterioration of his vision. Family history of diabetes and hypertension is noted. He engages in one hour of physical activity daily, including treadmill running and indoor cycling. Despite recent optical correction, his visual acuity remains at 3/10 unimproved. Ocular imaging, notably fluorescein retinal angiography and optical coherence tomography, reveals proliferative diabetic retinopathy with bilateral macular edema. Blood tests, performed after physical activity, show normal values of blood glucose and HbA1c, delaying the initiation of treatment and promoting the progression of retinopathy. Despite appropriate management, no significant improvement in visual function is observed during follow-up. Conclusion: The management of diabetic retinopathy requires an approach integrating physical activity. A better understanding of the interaction between physical activity and diabetic retinopathy is needed to optimize prevention and treatment strategies.展开更多

It is a common complication of human immunodeficiency virus (HIV) infection. The aim of this study was to describe the diagnostic and therapeutic aspects and to establish the correlation between PFP and HIV in our context. Patients and Method: This was a retrospective descriptive study conducted in the ENT and CFS department of the HIAOBO, covering the medical records of patients hospitalized for taking a PFP on HIV terrain from January 1, 2016 to December 31, 2020. Results: The study involved 17 patients, 10 men (59%) and 7 women (41%), a sex ratio of 1.4. The average age was 39 years with the extremes of 11 and 69 years. Shopkeepers reported 9 cases (53%). The reason for consultation was facial asymmetry in 11 cases (100%). The delay in consultation during the first week was 82.4%. Clinical signs were unilateral facial asymmetry, the opening of the palpebral fissure and lacrimation. All patients received medical treatment for PFP and HIV. Evolution was favorable, with complete recovery and no sequelae in 82.4% of cases. Surgery was performed in one case. Conclusion: PFPs are common in HIV infection. Diagnosis is clinical and management is multidisciplinary. Progression depends on the length of time taken to treat the disease.展开更多
