Evaluation of the quality of medical records in the Monastir regional hospitals--Tunisia

The aim of this study is to evaluate the quality of medical records throughout a sample of 380 records at the medicine ward of three regional hospitals in Monastir. The medical audit was performed using a reference standard previously developed by foreign teams and adapted to the health care features of our country. The results showed that the quality of medical records should be improved. It depends on the hospital and in 2/3 of cases there was a lack of information or sheets important for the coordination and the continuity of medical care. The quality improvement of medical records could be reached by the professional education, which should emphasise the importance of medical and administrative data in the health care management. This could be included in a continuous quality improvement program.     

The spectrum of Vogt-Koyanagi-Harada disease in Tunisia, North Africa

OBJECTIVE: To analyze the clinical profile of Vogt-Koyanagi-Harada (VKH) disease in Tunisia, North Africa. METHODS: We retrospectively reviewed the clinical records of 49 patients diagnosed with VKH disease at the Department of Ophthalmology of Fattouma Bourguiba University Hospital, Monastir, Tunisia, between January 1994 and September 2005. RESULTS: Of all the uveitis cases diagnosed during the study period, VKH disease was the fourth most commonly occurring type (7.4%). Thirty-two patients (65.3%) were female, and 17 patients (34.7%) were male. The mean age at disease onset was 35 years (range: 16-54 years). The majority of patients (51%) had probable VKH disease, followed by incomplete type (47%); only 2% had the complete type. At presentation, 47 patients (96%) had bilateral ocular involvement. Clinical presentation was a panuveitis in 25 patients (51%) and a posterior uveitis in 24 patients (49%). Visual acuity (VA) at presentation ranged from less than 20/200 (40.8%) to more than 20/40 (28.5%). All patients were treated with systemic corticosteroids for 2-19 months (mean: 10.5 months). Four patients (8%) were treated with cyclosporin because of serious systemic side effects of corticosteroids. Complications included cataract in 18 eyes (33.9%), glaucoma in nine eyes (16.96%) and choroidal neovascularization in one eye (1%). Fifty-eight eyes (59%) had a final VA of 20/40 or better. Factors associated with a poor VA at the final follow-up were the presence of a poor VA at presentation (P = 0.02), the occurrence of complications (P = 0.001) and/or recurrences (P = 0.02). CONCLUSION: In Tunisia, VKH disease is a common cause of uveitis that predominantly affects young women. The overwhelming majority (98%) have probable or incomplete VKH disease, presenting as panuveitis or posterior uveitis. More than 50% of patients undergoing treatment with corticosteroids will maintain a VA of 20/40 or better.     

Acute choroidal ischemia associated with toxoplasmic retinochoroiditis

PURPOSE: To describe eight patients with active toxoplasmic retinochoroiditis (RC) who had features suggestive of acute choroidal ischemia. METHODS: A retrospective review of the clinical records of 23 consecutive patients with acute toxoplasmic RC was performed. All patients underwent detailed ophthalmic examination at presentation and throughout follow-up, including dilated biomicroscopic fundus examination, fundus photography, fluorescein angiography, and indocyanine green (ICG) angiography. RESULTS: Of 23 patients, 8 (34.8%) had a large area of retinal whitening surrounding a small focus of RC. Fluorescein as well as ICG angiography showed a well demarcated geographic area of early choroidal hypofluorescence that extended beyond the clinical borders of the white retinal lesion, particularly by ICG angiography. Associated findings for these 8 patients included old retinochoroidal scars (7 [87.5%]), serous retinal detachment (3 [37.5%]), retinal hemorrhages (1 [12.5%]), and multiple satellite dark dots by ICG angiography (6 [75%]). Seven of eight patients were treated using a combination of antitoxoplasmic drugs and corticosteroids. All findings seen at the acute stage resolved in 2 weeks to 6 weeks. A small atrophic retinochoroidal scar replaced the active toxoplasmic lesion and was surrounded with mild or moderate retinal pigment epithelium changes that were associated with decreased final visual acuity in 2 patients (25%). CONCLUSION: Patients with toxoplasmic RC may develop features suggestive of choroidal ischemia that can result in a transient or permanent decrease in vision. Choroidal ischemia can only be suspected clinically, and fluorescein angiography and ICG angiography are required to establish the definitive diagnosis.     

Pattern of uveitis in a referral centre in Tunisia, North Africa

AIM: To analyse the pattern of uveitis in a referral centre in Tunisia, North Africa. METHODS: The study included 472 patients with uveitis examined at the Department of Ophthalmology of Monastir (Tunisia) from January 1992 to August 2003. All patients had a comprehensive ocular and systemic history, including an extensive review of medical systems. Complete ophthalmic examination was performed in all cases, including best-corrected Snellen visual acuity, slit-lamp examination, applanation tonometry, and dilated fundus examination with three-mirror lens. Standard diagnostic criteria were employed for all syndromes or entities of uveitis. RESULTS: The mean age at onset of uveitis was 34 years. The male-to-female ratio was 1:1.1. Uveitis was unilateral in 282 patients (59.7%) and bilateral in 190 patients (40.3%). Anterior uveitis was most common (166 patients; 35.2%), followed by posterior uveitis (133 patients; 28.2%), panuveitis (100 patients; 21.2%), and intermediate uveitis (73 patients; 15.5%). A specific diagnosis was found in 306 patients (64.8%). The most common cause of anterior uveitis was herpetic uveitis (56 patients; 33.7%). Toxoplasmosis was the most frequent cause of posterior uveitis (51 patients; 38.3%). Intermediate uveitis was most commonly idiopathic (63 patients; 86.3%). Beh?et's disease was the most common cause of panuveitis (36 patients; 36%), followed by Vogt-Koyanagi-Harada (VKH) disease (15 patients; 15%). A total of 16 patients (3.4%) suffered from blindness, and 59 (12.5%) from uniocular blindness. CONCLUSIONS: In a hospital population in Tunisia, the most common causes of uveitis were Beh?et's disease, herpes simplex infection, toxoplasmosis, and VKH disease.     

A novel 22 bp deletion in a Tunisian phenylketonuria family

Phenylketonuria (PKU) is an autosomal recessive metabolic disorder caused by a deficiency of phenylalanine hydroxylase. To date, more than 530 mutations in the PAH gene have been reported. In Tunisia, this disease seems to be the result of point mutations, few studies have been published about molecular defects of PKU in our country. In this study, we report a novel deletion in exon 6 of two brothers in a Tunisian family after DHPLC analysis and sequencing of the exon 6 of the PAH gene.     

Polysaccharides from the Green Alga Ulva lactuca Improve Antioxidant Balance and Bone Mineral Density in Diabetic Rats

Diabetes mellitus (DM), the 10th? leading cause of death worldwide, is a major and growing public health problem estimated to affect more than 578 million people in 2030 and 700 million people in 2045[1]. In diabetic animals, protein glycation and glucose autoxidation generate free radicals, which cause lipid peroxidation. Therefore, reactive oxygen species (ROS) can quickly accumulate, decrease antioxidant activity, and cause deterioration of kidney and liver function. A disrupted redox balance in cells also damages crucial biomolecules such as deoxyribonucleic acid (DNA), proteins and lipids. Oxidative stress (OS) is elevated in diabetes mellitus and may be a major factor in the development and evolution of the typical long-term pathophysiology of?diabetes?and?its?associated?complications[2].
