Abstract
An 18-year-old female patient was referred with complaints of tearing and redness in the left eye for 3 months after a mild ocular trauma with a turkey feather. She was treated with topical antibiotics and corticosteroids with no improvement. Slit-lamp examination of the left eye showed a vascularized lesion with a polypoidal appearance due to multiple contiguous micronodules on the temporal and inferior bulbar conjunctiva. Results of the anterior and posterior segment examination were unremarkable in both eyes. A biopsy specimen of the conjunctival mass showed multiple tuberculoid granulomas composed of epithelioid histiocytes with associated Langhan's type multinucleate giant cells and a necrotic nodule surrounded by histiocytes and giant cells. The Mantoux test was positive with induration of 15mm. The patient was prescribed antituberculosis therapy. Three months after treatment initiation, the conjunctival lesions had resolved. Mycobacterium tuberculosis should be considered in cases of unilateral chronic recalcitrant conjunctivitis. Biopsy of a conjunctival mass is of utmost importance to establish a definite diagnosis.

Abstract
PURPOSE To compare the macular and papillary parameters on optical coherence tomography (OCT) between the amblyopic eye and the healthy eye in subjects with unilateral strabismic or anisometropic amblyopia. PATIENTS AND METHODS This is a cross-sectional and comparative study carried out over two years, from April 1, 2019, to March 31, 2021. We included patients aged over 5years, followed for unilateral amblyopia, free of any neurological and/or ocular pathology. The evaluation of the macular and papillary parameters in the amblyopic and healthy eyes was performed with Swept-Source Optical Coherence Tomography (OCT-SS). The parameters were compared according to age group and type of amblyopia. RESULTS We collected 50 patients, 29 children, and 21 adults, with a mean age of 19.8years. Amblyopia was secondary to anisometropia in 40 patients and strabismus in 10 patients. Analysis of macular tomographic parameters found no significant difference between amblyopic eyes and healthy eyes for mean macular thickness (P=0.86), central macular thickness (P=0.86), or mean macular volume (P=0.54). The mean retinal peripapillary fiber thickness (RNFL) was 107.48μm in the amblyopic eye and 103.8μm in the healthy eye, with a statistically significant difference (P<0.001). This significant thickening of the RNFL in amblyopic eyes was present in adults (P<0.001), children (P<0.001), anisometropic (P<0.001), and strabismic amblyopia (P=0.024). Analysis of the other optic nerve head parameters revealed no significant difference between amblyopic eyes and healthy eyes in terms of optic disc surface area (P=0.89), neuro-retinal annulus surface area (P=0.47), vertical (P=0.98) or horizontal (P=0.74) cup to disc ratio. CONCLUSION Amblyopia is accompanied by thickening of the peripapillary retinal fibers without macular repercussions. However, larger prospective studies are needed to confirm these results.

Abstract
Abstract
Background
Uveitis in children represents 10% of all cases of uveitis. It is a serious condition with an often-insidious onset and evolution, and has a negative impact on visual prognosis with a risk of amblyopia or even blindness. The etiologies are varied. the aim of this study is to describe the epidemiological, clinical, and etiological characteristics of childhood uveitis during a period of 12 years.
Methods
A descriptive retrospective study including 138 children (276 eyes) with uveitis, was conducted at the Ophthalmology Department of Fattouma Bourguiba University Hospital in Monastir Tunisia between 1 January 2006 and 31 December 2017.
Results
The patients average age was 10.2 ± 3,58. A female predominance was noted (sex ratio: 0.91). Uveitis was bilateral in 2/3 of cases and unilateral in 1/3 of cases. Vision loss was the most common reason for consultation (52.2%). The mean initial visual acuity was 3,3/10 ± 3,24. Intermediate uveitis was the most common anatomical form (42,02%), followed by anterior uveitis (28,26%), panuveitis (26,08%), and posterior uveitis (3,6%). The infectious origin was the most common aetiology, followed by uveitis related to general condition (13,72%), and uveitis in context of a specific ocular condition (12,3%). Uveitis was idiopathic in 79 patients (57.24%). Periocular injection of triamcinolone acetonide was performed in (29 patients, 21%). The use of immunosuppressives agents was noted in 38 patients (27,5%) (methotrexate: 23 patients, azathioprine: 16 patients, and ciclosporin: 10 patients). The use of intravitreous injections of bevacizumab was noted in 6 patients (4.33%). Anti TNF alpha treatment was used for 2 patients. Post-uveitic complications were noted in 84.3% of cases. They were dominated by cataract (31,88%) at the anterior segment level. Cystoid macular oedema (31,88%) and retinal serous detachment (15,9%) were the major complications in the posterior segment. Mean final visual acuity was 5.98/10 ± 3,54. It was <1/10 in 14 eyes.
Conclusion
In our study a female predominance was noted. Intermediate uveitis was the most common anatomical form. The infectious origin was preponderant. Post-uveitic complications was dominated at the anterior segment level by cataract and cystoid macular oedema at the posterior segment.

Abstract
INTRODUCTION The goal of our study was to create a cross-cultural adaptation of the questionnaire « National Eye Institute Visual Function Questionnaire » (NEI-VFQ-25) for the Tunisian population (Tu-VFQ-25) and to test its psychometric properties in a group of patients with chronic uveitis. PATIENTS AND METHODS The study consisted of two steps. The first was translation of the NEI-VFQ-25 and its cross-cultural adaptation to the Tunisian dialect (Tu-VFQ-25) according to the guidelines of Beaton et al. The second step consisted of studying the psychometric properties of the Tu-VFQ-25. Enrolled patients, diagnosed with chronic uveitis, were interviewed face-to-face by two different investigators, followed by a telephone interview by the first investigator 48hours later. Feasibility, internal consistency and reproducibility of the Tu-VFQ-25 were then tested using statistical methods. RESULTS The mean time taken to administrate the questionnaire to each of the 45 patients was 11min 40 s (± 2min 24 s). Internal consistency was acceptable, with Cronbach's alpha coefficients above 0.7 except the "Ocular Pain" and "Driving" subscales (0.645 and 0.559 respectively). Inter-observer reliability was excellent, with intra-class correlation coefficients (ICC) ranging from 0.857 to 0.985 for all subscales. Test-retest reliability, assessed for 43 patients, was good to excellent, with ICC above 0.80 for all subscales except "General Vision," which had a value of 0.786. CONCLUSION As with previous versions, the Tu-VFQ-25 is an easy and reliable tool for assessing vision-related quality of life of Tunisian patients with chronic uveitis.

Abstract
PURPOSE To study the effect of ocular inflammation in active uveitis on the corneal endothelium. MATERIALS AND METHODS This is a prospective cross-sectional study involving 63 eyes of 38 patients with active newly-diagnosed uveitis. Eighty-four eyes of 42 non-uveitic subjects served as a control group. All patients underwent detailed ophthalmic examination, laser flare photometry, and non-contact specular microscopy. Eyes with uveitis had a follow-up visit at one month after initiation of treatment, including laser flare photometry and specular microscopy. RESULTS The mean age of the active uveitis patients was 33 (range: 9-67 years) with 21 men (55%) and 17 women (45%). For the uveitis patients at baseline, the mean flare value was 32ph/ms (range: 15-100ph/ms) with flare photometry value ≥50ph/ms in 13 eyes (21%) and<50ph/ms in 50 eyes (79%). At baseline, cell density (CD) of the uveitis patients was similar to CD in control eyes (p꞊0.16). The percent of hexagonality was significantly lower (p<0.0001), and the coefficient of variance (CV) (p<0.0001) and central corneal thickness (CCT) (p<0.0001) were significantly higher than in the control group. After one month, there was a significant decrease in flare photometry values (p<0.0001), with a mean flare value of 14.5ph/ms (range: 4-60ph/ms). In the active uveitis group, the overall results of specular microscopy did not significantly vary between the initial examination and the 1-month examination. For eyes with flare photometry value ≥50ph/ms at baseline, CD and hexagonal cell count significantly increased on the 1-month examination (p꞊0.01 and p꞊0.02 respectively), while CV and CCT decreased significantly at the one-month follow-up visit (p꞊0.007/p꞊0.03 respectively). For eyes with flare photometry value at baseline <50ph/ms, there was no significant differences in specular microscopy results between the initial examination and the 1-month examination. CONCLUSIONS In eyes with newly-diagnosed uveitis and active anterior chamber inflammation, specular microscopy shows transient qualitative abnormalities of the corneal endothelium that depend on the severity of the anterior chamber inflammation as measured by the laser flare meter.

Abstract
Background Mitogen‐activated protein kinase–activated protein kinase‐2 (MK2) is a protein serine/threonine kinase activated by p38α/β. Herein, we examine the cardiac phenotype of pan MK2‐null (MK2−/−) mice. Methods and Results Survival curves for male MK2+/+ and MK2−/− mice did not differ (Mantel‐Cox test, P=0.580). At 12 weeks of age, MK2−/− mice exhibited normal systolic function along with signs of possible early diastolic dysfunction; however, aging was not associated with an abnormal reduction in diastolic function. Both R‐R interval and P‐R segment durations were prolonged in MK2‐deficient mice. However, heart rates normalized when isolated hearts were perfused ex vivo in working mode. Ca2+ transients evoked by field stimulation or caffeine were similar in ventricular myocytes from MK2+/+ and MK2−/− mice. MK2−/− mice had lower body temperature and an age‐dependent reduction in body weight. mRNA levels of key metabolic genes, including Ppargc1a, Acadm, Lipe, and Ucp3, were increased in hearts from MK2−/− mice. For equivalent respiration rates, mitochondria from MK2−/− hearts showed a significant decrease in Ca2+ sensitivity to mitochondrial permeability transition pore opening. Eight weeks of pressure overload increased left ventricular mass in MK2+/+ and MK2−/− mice; however, after 2 weeks the increase was significant in MK2+/+ but not MK2−/− mice. Finally, the pressure overload–induced decrease in systolic function was attenuated in MK2−/− mice 2 weeks, but not 8 weeks, after constriction of the transverse aorta. Conclusions Collectively, these results implicate MK2 in (1) autonomic regulation of heart rate, (2) cardiac mitochondrial function, and (3) the early stages of myocardial remodeling in response to chronic pressure overload.

Abstract
PURPOSE Polymorphisms of the engulfment and cell motility 1 (ELMO1) gene were recently associated with type 2 diabetes (T2DM) and its complications. We investigated the association of rs10255208, rs7782979, and rs2041801 ELMO1 gene variants with T2DM in Tunisian Arabs. METHODS Subjects comprised 900 T2DM patients and 600 normoglycemic controls. ELMO1 genotyping was done by PCR-RFLP; the contribution of ELMO1 variants to T2DM was analyzed by Haploview and regression analysis. RESULTS Minor allele frequencies of rs7782979 and rs10255208 ELMO1 variants were significantly higher among unselected T2DM cases than controls, and significant differences in the distribution of rs7782979 genotypes were seen between T2DM cases and control subjects, which was seen in male but not female subjects. Three-locus ELMO1 haplotype analysis identified haplotype GAA to be positively associated, and haplotypes GCA, AAA, and GCG to be negatively associated with T2DM. The distribution of these haplotypes was gender-dependent for some (GCA, GCG, AAG), and gender-independent for others (GAA, AAA). This translated into altered risk of T2DM in male or female subjects, which persisted after adjusting for BMI, systolic and diastolic blood pressure, and serum lipid profile. CONCLUSION These results confirm role for ELMO1 as T2DM susceptibility locus, which appears to be gender-dependent.

[Incidence and causes of visual impairment in the district of Mahdia, in east Tunisia: Retrospective study of 1487 cases]. J Fr Ophtalmol 2016; 39:771-779. [PMID: 27745894 DOI: 10.1016/j.jfo.2016.07.008] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2016] [Revised: 05/03/2016] [Accepted: 07/04/2016] [Indexed: 11/24/2022]
Abstract
OBJECTIVE To study socio-demographic characteristics and main causes related to visual impairment (VI) as a function of age bracket and to analyze their trends over time in the district of Mahdia. METHOD A retrospective review was performed on 1487 cases of visual impairment registered with the social authorities in Mahdia, between 1980 and 2013. The social, demographic, vision exam findings and causes were ascertained and analyzed in an SPSS database. Incidence rates of VI and blindness due to various causes were calculated based on the demographic data from the NSI to estimate the time trends using the general linear regression model and Spearman correlation. RESULTS Analyses included 1487 participants with a median age of 47 years, 40.6% of cases were aged under 45 years. Children accounted for 11.1% (165 patients), while age was between 16 and 45 years in 29.5% (439 patients), between 46 and 65 years in 31.5% (469 patients) and greater than 65 years in 27.8% (414 patients). The sex-ratio (M/F) was 1.78. Socially, 51% came from rural areas, 62% were illiterate, and 84% were unemployed. We observed blindness in 70% of participants and low vision in 30%. In children, the causes were dominated by congenital cataract and congenital glaucoma, each present in 31 children (18.8%). Between 16 and 45 years, glaucoma and hereditary dystrophies of the retina were found in 62 and 61 patients respectively (14% each). For age between 46 and 65 years, trachoma was responsible for 19.8% of cases of VI, glaucoma in 15.8% and cataract in 15.1%. Beyond 65 years, glaucoma accounted for 30.7% of the causes of VI and cataract 27.8% of cases. Trend analysis shows a significant increase in the incidence rate of visual impairment with an average of 12% per year (P=0.001). The mean age increased by 46% (P=0.003). Trachoma increased by 118% (P<0.0001) between 1980 and 1990, then declined by 42% (P=0.0013) between 1991 and 2013. Incidence of VI significantly increased by 4% for cataract (P=0.001), 23% (P=0.001) for glaucoma and 20% (P=0.02) for diabetic retinopathy, while VI related to refractive errors and AMD showed no significant change. CONCLUSION Advanced age, lower educational and socio-economic status were associated with bilateral VI. Age related eye problems are the main causes of VI, and their incidence is tending to increase. Public health policies and procedures should be targeted to risk related populations and age-related diseases in order to control the incidence of visual impairment and avoid its consequences.

Abstract
BACKGROUND/AIMS Renal function decreases over time as a result of reduction in the number of functioning nephrons with age. In recipients and donors of kidney grafts, renal function decline may be linked differently to various parameters, namely arterial stiffness. METHODS We conducted a prospective cohort study including 101 recipients of kidney grafts and their donors aiming at determining the factors correlated to the renal function decline over time. Aortic stiffness was evaluated by the non-invasive measurement of aortic pulse wave velocity. The glomerular filtration rate was estimated using the Modification of Diet in Renal Disease (MDRD) equation and the annualized change was determined. RESULTS Decline in renal function was estimated at 1-year post-transplantation and annually thereafter (median follow-up 8 years, range 3.6-18.3), as the mean of the annualized decrease in the glomerular filtration rate. In recipients, filtration rate decreased by 4.8 ± 19.7 ml/min/1.73 m(2) the first post-transplant year and at a yearly rate of 2.2 ± 3.8 ml/min/1.73 m(2) thereafter. The first-year decline was related to smoking and acute rejection. Later decline was significantly associated with donor age and aortic stiffness. In living donors, renal function decline after the first year corresponded to 0.7 ml/min/1.73 m(2), was significantly lower than that of recipients (p < 0.001), and was determined by donor age at nephrectomy. CONCLUSION Recipients of kidney grafts show a glomerular filtration rate decline over time that is significantly associated with donor age and aortic stiffness after the first post-transplant year, while donors demonstrate a lower decline that is mostly determined by age at nephrectomy.

Abstract
PURPOSE To investigate the prevalence and causes of blindness and partial sight among a population of Tunisian diabetic patients. METHODS A cross-sectional study of 2320 randomly identified patients with diabetes mellitus. Patient's characteristics as well as data from the last ophthalmic examination were reviewed. RESULTS Of all patients examined, 60.2% were females and 39.8% were males. Mean age of patients was 54.5 years. Mean duration of diabetes was 7.6 years. Diabetic retinopathy (DR) was recorded in 26.3% of patients, and was proliferative in 3.4% of patients. The prevalence of visual impairment was 22.2%, with 4.4% patients legally blind and 17.8% partially sighted. Visual impairment was significantly associated with age ≥60 years (P<0.001), duration of diabetes >10 years (P<0.001), body mass index >25 (P=0.014), hypertension (P<0.001), heart disease (P<0.001), peripheral neuropathy (P=0.03), vegetative neuropathy (P=0.002), macroalbuminuria (P<0.001), cataract (P<0.001), DR (P<0.001), diabetic macular edema (P<0.001), open angle glaucoma (P<0.001), intravitreal hemorrhage (P<0.001), rubeosis iridis (P<0.001), neovascular glaucoma (P<0.001), and tractional retinal detachment (P<0.001). CONCLUSION The current report is the largest study of DR in North African region. It provides a baseline data against which future progress can be assessed. Screening and treatment can greatly reduce the incidence of visual impairment due to diabetes.

Abstract
PURPOSE Previous studies have shown that the standardized patient's (SP) gender may affect student performance in an Objective Structured Clinical Examination (OSCE). The aim of this study is to investigate the influence of the SPs' body habitus on students' performance in an OSCE counseling station. METHODS Four equally trained female SPs, with either a normal or an obese BMI participated in an OSCE counseling station for cardiovascular risk factors. Ninety-two, second year medical students were randomly assigned to one of the SPs. Station scores were compared and student behavior and opinion regarding the influence of their SP's body habitus on their performance was assessed. RESULTS There was no difference in mean exam scores for students interacting with SPs with a normal BMI versus increased BMI (14.9 ± 2.2 versus 14.01 ± 2.2/20 respectively, p = 0.06). Additionally, almost all students gave advice about healthy diets (93.5% versus 95.7%) with no specificity regarding the BMI of the SP. CONCLUSIONS The body habitus of the SP did not significantly affect students' performance in an undergraduate OSCE about cardiovascular risk factors, suggesting that students at that level may primarily focus on gaining points the diagnostic checklist without considering SPs as real patients.

Abstract
Chronic hemodynamic overload results in left ventricular hypertrophy, fibroblast proliferation, and interstitial fibrosis. The small heat shock protein hsp27 has been shown to be cardioprotective and this requires a phosphorylatable form of this protein. To further understand the regulation of hsp27 in heart in response to stress, we investigated the ability of elevated aortic pressure to activate hsp27-kinase activities. Isolated hearts were subjected to retrograde perfusion and then snap frozen. Hsp27-kinase activity was measured in vitro as hsp27 phosphorylation. Immune complex assays revealed that MK2 activity was low in non-perfused hearts and increased following crystalline perfusion at 60 or 120 mmHg. Hsp27-kinase activities were further studied following ion-exchange chromatography. Anion exchange chromatography on Mono Q revealed 2 peaks (b and c) of hsp27-kinase activity. A third peak a was detected upon chromatography of the Mono Q flow-through fractions on the cation exchange resin, Mono S. The hsp27-kinase activity underlying peaks a and c increased as perfusion pressure was increased from 40 to 120 mmHg. In contrast, peak b increased over pressures 60-100 mmHg but was decreased at 120 mmHg. Peaks a, b, and c contained MK2 immunoreactivity, whereas MK3 and MK5 immunoreactivity was detected in peak a. p38 MAPK and phospho-p38 MAPK were also detected in peaks b and c but absent from peak a. Hsp27-kinase activity in peaks b and c (120 mmHg) eluted from a Superose 12 gel filtration column with an apparent molecular mass of 50 kDa. Hence, peaks b and c were not a result of MK2 forming complexes. In-gel hsp27-kinase assays revealed a single 49-kDa renaturable hsp27-kinase activity in peaks b and c at 60 mmHg, whereas several hsp27-kinases (p43, p49, p54, p66) were detected in peaks b and c from hearts perfused at 120 mmHg. Thus, multiple hsp27-kinases were activated in response to elevated aortic pressure in isolated, perfused rat hearts and hence may be implicated in regulating the cardioprotective effects of hsp27 and thus may represent targets for cardioprotective therapy.

Abstract
p38 mitogen-activated protein kinases (MAPKs) regulate a broad range of cellular activities but have been implicated in the pathogenesis of cardiovascular diseases. The mechanisms whereby p38 exerts divergent effects are unknown. Current p38 inhibitors both produce serious side effects and loose efficacy with chronic use. Hence, a better understanding of the downstream targets of p38, i.e. MAPK-activated protein kinases (MKs), is essential. We hypothesized that inhibition of MK2 activity (MK2-/-) during chronic pressure overload is cardioprotective. Twelve-week-old MK2-/- and littermate control (MK2+/+) mice were subjected to transverse aortic constriction (2 wks, n=8). MK2-/- mice showed a ∼20% reduced increase in heart weight-to-tibia length ratio (Fig A) despite similar increases in mean blood pressure and ANP expression. Compared to controls, banded MK2-/- hearts also showed preserved left ventricular: (i) fractional shortening, (ii) ejection fraction (preserved at 72.5 ± 2.2% after banding for MK2-/- but decreased from 67.9 ± 3.6% to 58.8 ± 3.4% in MK2+/+, p<0.05, Fig B), and (iii) diastolic function evidenced by the ratio of transmitral and myocardial early diastolic velocities (E/Em preserved after banding in MK2-/- but increased by 78.8 ± 11.1% in MK2+/+, p<0.01). MK2 deficiency did not reduce interstitial fibrosis. For equivalent respiration rates, mitochondria from MK2-/- hearts showed a significant decrease in Ca2+-sensitivity for mitochondrial permeability transition pore opening (p<0.05, Fig C). Overall, these results suggest that MK2 mediates part of the detrimental remodeling evoked by chronic pressure overload-induced activation of p38.

Abstract
Susceptibility of cardiomyocytes to stress-induced damage has been implicated in the development of cardiomyopathy in Duchenne muscular dystrophy, a disease caused by the lack of the cytoskeletal protein dystrophin in which heart failure is frequent. However, the factors underlying the disease progression are unclear and treatments are limited. Here, we tested the hypothesis of a greater susceptibility to the opening of the mitochondrial permeability transition pore (PTP) in hearts from young dystrophic ( mdx) mice (before the development of overt cardiomyopathy) when subjected to a stress protocol and determined whether the prevention of a PTP opening is involved in the cardioprotective effect of sildenafil, which we have previously reported in mdx mice. Using the 2-deoxy-[3H]glucose method to quantify the PTP opening in ex vivo perfused hearts, we demonstrate that when compared with those of controls, the hearts from young mdx mice subjected to ischemia-reperfusion (I/R) display an excessive PTP opening as well as enhanced activation of cell death signaling, mitochondrial oxidative stress, cardiomyocyte damage, and poorer recovery of contractile function. Functional analyses in permeabilized cardiac fibers from nonischemic hearts revealed that in vitro mitochondria from mdx hearts display normal respiratory function and reactive oxygen species handling, but enhanced Ca2+ uptake velocity and premature opening of the PTP, which may predispose to I/R-induced injury. The administration of a single dose of sildenafil to mdx mice before I/R prevented excessive PTP opening and its downstream consequences and reduced tissue Ca2+ levels. Furthermore, mitochondrial Ca2+ uptake velocity was reduced following sildenafil treatment. In conclusion, beyond our documentation that an increased susceptibility to the opening of the mitochondrial PTP in the mdx heart occurs well before clinical signs of overt cardiomyopathy, our results demonstrate that sildenafil, which is already administered in other pediatric populations and is reported safe and well tolerated, provides efficient protection against this deleterious event, likely by reducing cellular Ca2+ loading and mitochondrial Ca2+ uptake.
