ABSTRACT
AIM: The aim of this study was to assess ocular and mucocutaneous sequelae among SJS/TEN survivors and identify risk factors of ocular sequelae. PATIENTS AND METHOD: Late complications among SJS/TEN survivors were assessed using 2 methods: a retrospective assessment of medical records only or a retrospective assessment of medical records and physical examination of survivors who were contacted by phone. RESULTS: Between January 1995 and December 2017, 177 cases of SJS/TEN (138 cases of SJS, 29 cases of TEN, and 10 cases SJS/TEN overlap) were admitted into two university hospitals of Lomé (Togo). There were 113 women and 64 men, with an average age of 31.7±13.0 years (range: 5 to 80 years). The most used drugs were antibacterial sulfonamides (35.6%) and nevirapine (24.3%). HIV serology was positive in 68 (59.1%) of the 115 patients tested. Sixty-four (52,5%) of the 122 patients, who had been examined by an ophthalmologist during the acute stage, had acute ocular involvement, which was mild in 27.9% of patients, moderate in 13.1%, and severe in 11.5%. We recorded 17 deaths (i.e., three cases of SJS, 12 of TEN, and two of SJS/TEN overlap), including 11 cases of HIV infected patients. Of the 160 SJS/TEN survivors, only 71 patients were assessed 6 months after hospital discharge. Among them, forty-three (60.6%) patients had sequelae. Concerning mucocutaneous sequelae, the main lesions were diffuse dyschromic macules (38.0% of patients) and ocular sequelae were dominated by decreased visual acuity (14.1% of patients). In multivariate analysis, exposure to sulfadoxine (odds adjusted ratio = 5.95; 95%CI= [1.36-31.35]) and moderate (adjusted odds ratio = 5.85; 95%CI = [1.23-31.81]) or severe (adjusted odds ratio = 48.30; 95%CI = [6.25-1063.66]) ocular involvement at acute stage were associated with ocular sequelae. CONCLUSION: Ocular and mucocutaneous sequelae are common in SJS/TEN survivors. Exposure to sulfadoxine and severity of acute ocular involvement are risk factors of ocular sequelae.
ABSTRACT
INTRODUCTION: Retinal detachment poses management problems in developing countries due to the shortage of technical equipment. Prevention passes through knowledge and elimination of risk factors. This study aimed to identify the risk factors for retinal detachment in people living in Togo. METHODS: We conducted a retrospective and descriptive study in the Department of Ophthalmology at the Chu-Campus and in an ophthalmology office in Lomé from 2 January 2011 to 31 December 2015. The medical records of patients with retinal detachment were included in the study. The diagnosis of retinal detachment was confirmed based on funduscopic exam or ocular ultrasound. RESULTS: in total, 116 eyes of 100 patients had retinal detachment of whom 40 in the RE, 44 in the LE and 16 bilaterally. The average age of patients was 46.65 ± 16.46 years [07 years; 87 years], with a male predominance and with a sex-ratio = 0.32 (W/M). Diabetic patients accounted for 17% and patients with sickle cell disease accounted for 16%. Myopic patients accounted for 5%, pseudophakic patients accounted for 17.2% and aphakic patients accounted for 3.4%. Four patients had retinal tear (14.28% of rhegmatogenous detachment) including 2 superotemporal tears, 1 inferior nasal tear and 1 inferior temporala tear. 35 eyes (52.2%) had total retinal detachment while 24 eyes (35.8%) had partial retinal detachment. Twenty eyes had vitreoretinal proliferations, 5 eyes had itreous hemorrhage and 6 eyes had hyalite. Diabetes and sickle cell disease were the risk factors for tractional RD (p=0.006 and p=0.0003) while cataract surgery was the risk factor for rhegmatogenous RD (p=0.0097). CONCLUSION: Diabetes, sickle cell anemia and eye surgery were the major risk factors for RD. A better management of these pathologies and ophthalmologist's mastery of cataract surgery may prevent retinal detachment.
