Ocular involvement in pediatric Behçet's disease: is it different than in adults? (a short case series and mini review).

BACKGROUND: Pediatric Behçet's disease (PBD) is rarer than BD and can be a challenging diagnosis as clinical picture may be incomplete. As in adult patients, sight-threatening ocular manifestations may lead to diagnosis. In this study, we aimed to report a series of cases of PBD with ocular manifestations and provide a review of the literature. METHODS: Retrospective case series of PBD patients with ocular manifestations. Demographic, ophthalmological and systemic data at presentation and during follow-up were collected and analyzed. RESULTS: Four patients, aged 13.0 ± 2.9 years (9-16) were included. Posterior uveitis with retinal vasculitis, papillitis and macular edema was present in all patients, with associated anterior uveitis in 2 cases. Other features included occlusive vasculitis (2/4) and necrotizing retinitis (2/4). All patients were improved by systemic treatments except one patient with severe bilateral optic neuropathy. Ocular manifestations were the presenting symptoms in 3/4 cases. CONCLUSION: Ocular manifestations and systemic associations of PBD are comparable to those encountered in adult patients. The lack of complains in pediatric patients may lead to a longer diagnosis delay, especially in unilateral uveitis. Aggressive and long-term treatment is mandatory to prevent vision loss and recurrences.

Effect of perceived stigma on work and social roles among individuals with mental health disorders in Saudi Arabia: findings from a national survey.

BACKGROUND: It is known worldwide that stigma towards mental illness exists. Studies on stigma perceived by patients with mental illness have shown decreased quality of life and a negative impact on work, school and social life. The aim of this study was to estimate the prevalence of perceived stigma among respondents who had been diagnosed with a mental illness during the past 12 months, its association with socio-demographic variables and its effect on work and social roles limitations among Saudis. METHODS: The Saudi National Mental Health Survey (SNMHS) data were used for the analysis. The SNMHS is a nationally representative survey that was conducted using face-to -face interviews with Saudi individuals (age 15-65) in their households. Respondents were diagnosed (N = 639) with mental disorders based on a well-validated questionnaire-the Composite International Diagnostic Interview (CIDI) 3.0. Two dimensions from CIDI assessed perceived stigma: embarrassment and perceived discrimination. RESULTS: The prevalence of perceived stigma was 27.8% among mentally ill respondents. Stigma was lower among respondents who didn't seek any type of treatment than those who sought treatment OR = 0.28 (95% CI 0.084-0.935, P = 0.03). Respondents who reported perceived stigma had more work role limitations (OR = 1.1 95% CI 1.01-0.10 P 0.006) and social limitations (OR = 1.3 95% CI 0.99-1.62 P 0.05) than respondents who didn't report stigma. CONCLUSION: Perceived stigma is experienced by mentally ill individuals and it negatively affects their work and social roles. Awareness programs to remove stigma and educate the public are needed to be established by policymakers and healthcare providers in Saudi Arabia.

Failure of systemic oral doxycycline in preventing ocular toxoplasmic retinochoroiditis in French military personnel.

This paper describes two cases of toxoplasmic chorioretinitis presenting in two French soldiers who had been receiving oral doxycycline for malaria prophylaxis. This is despite the proven effectiveness of oral doxycycline in treating Toxoplasma gondii, the most common cause of this infection. The lack of effectiveness of oral doxycycline in these two cases most likely reflected that the ocular concentration of 100 mg daily doxycycline is too low to treat or prevent Toxoplasmic retinochoroiditis (TC). Clinicians should therefore be aware that soldiers taking prophylactic oral doxycycline are still at risk of developing ocular TC with potentially sight-threatening consequences if not treated adequately.

Assessing attitudes toward mental health illnesses in Saudi Arabia: A national cross-sectional study.

OBJECTIVES: The study aimed to assess the national attitudes toward individuals with mental health illnesses in Saudi Arabia, exploring the relationship between these attitudes and various sociodemographic factors. METHODS: A cross-sectional design with computer-assisted telephone interviews was employed, covering all 13 administrative regions in Saudi Arabia. A total of 4,533 adults agreed to participate, and their attitudes toward people with mental illnesses (PWMI) were measured using an 11-item scale. The translation of the original English version of the PWMI to Arabic was validated and published previously. The scale used level of agreement on a 5-point Likert scale. The score varies from 11 to 55, where a higher score signifies higher stigma. The associations between total PWMI scores and sociodemographic variables were analyzed using linear regression. RESULTS: The mean age of participants was 35.92 ± 12.84, with equal distribution across regions. The linear regression model showed significant associations between total PWMI scores and gender, education level, marital status, living with, or being friends with someone diagnosed with a mental illness, and working in healthcare. No significant associations were found with age, income level, and previous mental health diagnosis. The study suggests that negative stereotypes about mental illness may be more prevalent in Saudi Arabia, while Saudi participants had a more optimistic view regarding the recovery and outcomes of mental illnesses. CONCLUSIONS: The study highlights the importance of assessing mental health stigma and its associations with sociodemographic factors in Saudi Arabia. The significant associations found point to the need for targeted interventions and public health campaigns to address misconceptions and stereotypes surrounding mental health, ultimately improving the societal acceptance and well-being of individuals with mental health illnesses.

Efficacy, Safety, and Outcomes following Accelerated and Iontophoresis Corneal Crosslinking in Progressive Keratoconus.

PURPOSE: To investigate the outcomes of accelerated (A-CXL) and iontophoresis (I-CXL) corneal crosslinking in a large retrospective cohort with progressive keratoconus. METHODS: This retrospective observational cohort study included consecutive patients treated by A-CXL (9 mW/5.4 J/cm2) or I-CXL with a minimal follow-up of 12 months. Visual acuity, manifest refraction, topography, specular microscopy, and corneal optical coherence tomography (OCT) were evaluated at baseline and at the last visit. Progression was defined as an increase in the maximum topographic keratometry (Kmax) of 1D. RESULTS: 302 eyes of 241 patients with a mean age of 25.2 ± 7.5 years were included from 2012 to 2019: 231 and 71 eyes in the A-CXL and I-CXL groups, respectively. The mean follow-up was 27.2 ± 13.2 months (maximum: 85.7 months). Preoperatively, the mean Kmax was 51.8 ± 4.0D, with no differences between groups. Mean topographic measurements and spherical equivalent remained stable during the follow-up. At the last visit, CXL failure was reported in 60 eyes (19.9%): 40 (14.7%) versus 20 (28.2%) in A-CXL versus I-CXL, respectively, p = 0.005. The likelihood of progression after CXL was significantly higher following I-CXL: RR = 1.62, CI95 = [1.02 to 2.59], p = 0.04. Demarcation line presence at 1 month was positively correlated with higher efficacy of CXL, p = 0.03. No endothelial damage was reported, especially in 51 thin corneas (range = 342-399 µm). CONCLUSIONS: A-CXL seems more effective than I-CXL in stabilizing keratoconus; this is to be taken into account when a therapeutic indication is posed according to the aggressiveness of the keratoconus.

Cultural adaptation and validation of the mental illness associated stigma scale for Arabic-speaking population in Saudi Arabia.

Objective: This research aimed to culturally adapt and validate the MIAS scale for Arabic-speaking individuals within the Saudi Arabian general population, with an emphasis on cultural, societal, and individual nuances. Methods: An initial pilot testing with a small group ensured the scale's clarity. Subsequently, two cross-sectional studies involving 189 participants to assess structural validity of the Arabic MIAS scale, and 38 participants to assess the test-retest reliability. Descriptive statistics, Cronbach's α, Intraclass Correlation Coefficient (ICC), and Confirmatory Factor Analysis (CFA) were employed for data analysis. Results: The Arabic MIAS scale demonstrated good internal consistency and acceptable test-retest reliability (ICC α = 0.631). A three-factor model emerged (CFI = 0.890, TLI = 0.845, RMSEA = 0.094), including "Outcomes," "Negative Stereotypes," and "Recovery," closely mirroring the original study's structure. one item was excluded from the model since it didn't align with any of the three factors. Conclusion: The study contributes a culturally adapted, validated, non-condition-specific tool to gauge public attitudes toward mental health stigma in an Arabic context. It highlights the need for culturally sensitive stigma research and interventions and underscores the importance of improving such tools for cross-cultural applicability and comparability.

Using pre-existing social networks to determine the burden of disease and real-life needs in rare diseases: the example of Thygeson's superficial punctate keratitis.

BACKGROUND: Thygeson's superficial punctate keratitis (TSPK) is a rare and still poorly understood disease of the ocular surface, responsible for recurrent episodes of photophobia and eye pain. While TSPK is considered as a benign condition, a subset of patients has frequent recurrences or even chronic disease, two situations in which there are currently no therapeutic guidelines. We used a preexisting Facebook TSPK patient support group to assess the clinical journey and the burden of disease of TSPK. RESULTS: An online survey was sent to the patient support group. The first part of the questionnaire gathered information on demographics and the patient's clinical journey [diagnostic modalities, symptoms, duration and frequency of recurrent episodes (RE), efficacy and tolerance to treatments]. The second part focused on quality of life (QoL) using the Ocular Surface Disease-QoL (OSD-QoL) questionnaire. Seventy-two patients out of 595 members of the support group completed the questionnaire during the 3-months study period. Eighty percent of patients developed symptoms before 30 years old, and 47% reported a delay in the diagnosis above 1 year. Sixty percent of patients reported over 5 RE yearly, and 18% of RE lasted more than 3 months. Forty percent of all patients used cyclosporine eyedrops (50% of those with > 5 episodes/year) and it was perceived as effective by 72% of these patients. The impact on daily life activities was judged as severe by 22% of patients, while 38% reported reduced professional activity and 80% were deeply saddened by their eye condition. CONCLUSION: TSPK patients may present with frequent recurrences and/or chronic disease, that result in a severe impact on QoL, and an off-label use of topical immunomodulatory eye drops, suggesting the urgent need for controlled studies. The utility of using social networks for rare ophthalmic disease research includes, faster data collection, data from patients across the globe, and also raises relevant questions about their real needs.

Laser Doppler holography of the anterior segment for blood flow imaging, eye tracking, and transparency assessment.

Laser Doppler holography (LDH) is a full-field blood flow imaging technique able to reveal human retinal and choroidal blood flow with high temporal resolution. We here report on using LDH in the anterior segment of the eye without making changes to the instrument. Blood flow in the bulbar conjunctiva and episclera as well as in corneal neovascularization can be effectively imaged. We additionally demonstrate simultaneous holographic imaging of the anterior and posterior segments by simply adapting the numerical propagation distance to the plane of interest. We used this feature to track the movements of the retina and pupil with high temporal resolution. Finally, we show that the light backscattered by the retina can be used for retro-illumination of the anterior segment. Hence digital holography can reveal opacities caused by absorption or diffusion in the cornea and eye lens.

Neurotrophic keratitis: Frequency, etiologies, clinical management and outcomes.

PURPOSE: To determine neurotrophic keratitis (NK) frequency, etiologies and prognostic factors, and evaluate the outcome of its management. METHODS: In this retrospective epidemiologic study, we reviewed the electronic records of all patients consulting our tertiary referral eye hospital between November 2009 and October 2017. NK was defined as corneal hypoesthesia or anesthesia associated with epithelial irregularities. RESULTS: Among the 305,351 patients' files screened for eligibility, 335 (354 eyes) were included, yielding an NK frequency of 11/10,000 (0.11%). Their mean ± SD age was 63.1 ± 21.0 years. Eyes were equally divided among the Mackie classification 3 stages. The most frequent etiology was herpetic eye disease (114 eyes; 32.2%). A multifactorial cause was found for 121 (34.2%) eyes. Surgery required for 118 eyes (33.3%). Respective success rates for amniotic membrane transplantation (AMT) or matrix-regeneration of stages 2 and 3, and autologous serum of stage 1 were 57.2%, 63.6% and 21.7%, with mean healing times of 15.0, 16.3 and 85 days. The overall healing rate was 79.5%, with a mean of 44.8 days to healing. Advanced initial stage, diminished corrected-distance visual acuity (CDVA) and advanced age correlated with worse final CDVA. CONCLUSIONS: NK was more frequent than previously reported in the literature. Delayed diagnoses indicated we must increase ophthalmologists' awareness of this disease for patients with decreased corneal sensitivity and abnormal epithelium. To improve prognosis and final CDVA, NK-specific treatment should be initiated as soon as the diagnosis is suspected. Patient-centered combinations of different therapeutic components and close monitoring achieved promising results.

Stigmatizing attitudes of tertiary hospital physicians towards people with mental disorders in Saudi Arabia.

OBJECTIVES: To measure stigma among doctors in one of the major specialized hospitals in Saudi Arabia. METHODS: This cross-sectional study was conducted at King Abdullah Medical City, Jeddah, Saudi Arabia between October and November 2018. Eighty physicians were recruited in this study. The participants administered the sociodemographic questionnaire as well as the Mental Illness Clinicians' Attitude 4th version (MICA 4). RESULTS: The overall MICA score ranged between 31 and 61 with a mean±SD of 45.75±7.54. The highest reported score was among outpatient physicians (51.33±6.66), while the lowest score was among consultants/assistant consultants (43.17±7.82). CONCLUSION: The results of this study showed a relatively high MICA-4 score that could indicate a high stigmatizing attitude among physicians toward patients with mental illnesses compared with the other MICA-4 studies. Thus, training workshops could improve the attitudes in the short-term.
