Peripapillary pachychoroid syndrome successfully treated with topical prednisolone acetate 1% drops.

Peripapillary pachychoroid syndrome (PPS) is a rare disease characterized by choroidal thickening around the optic disc. Visual acuity might be impaired secondary to the associated peripapillary intraretinal and/or subretinal fluids. We reported a case of a 70-year-old male patient who presented with a gradual bilateral decrease in vision. His best-corrected visual acuity was 20/60 in the right eye and 20/25 in the left eye. Dilated fundus examination showed yellowish peripapillary lesions and intraretinal fluid (IRF) surrounding the optic disc in both eyes. Optical coherence tomography showed that the outer retinal layers were disrupted, and IRF affected the nasal macula. A bilateral increase in the thickness of the choroid around the optic discs was found. The patient was successfully treated with a tapering dose of topical prednisolone acetate (1%). Three months after treatment, his vision improved to 20/25 in the right eye and 20/20 in the left eye. Topical steroid drops might be administered to treat PPS.

Prognostic value of pretreatment indocyanine green angiography in the acute uveitic phase of Vogt-Koyanagi-Harada disease.

PURPOSE: To investigate the prognostic value of pretreatment indocyanine green angiographic (ICGA) features in initial-onset acute uveitis associated with Vogt-Koyanagi-Harada (VKH) disease. METHODS: Retrospective analysis of 84 patients (168 eyes). Main outcome measures were final visual acuity, development of 'sunset glow fundus' (SGF) and progression to chronic recurrent evolution. RESULTS: Thirty-eight patients (76 eyes) presented in the phase preceding anterior segment (AS) inflammation (early presentation) and 46 patients (92 eyes) had AS inflammation at presentation (late presentation). The mean number of hypofluorescent dark dots (HDDs) and frequency of disc hyperfluorescence were more in the late presentation group (p < 0.001 for both comparisons), whereas the early presentation group showed higher frequencies of peripapillary punctate choroidal hyperfluorescence (p < 0.001) and hypofluorescent patches involving macula corresponding to the areas of exudative retinal detachment (p = 0.012). The mean number of HDDs and the frequency of disc hyperfluorescence were higher among eyes that developed SGF (p < 0.001 for both comparisons) and eyes that progressed to chronic recurrent evolution (p < 0.001; p = 0.001, respectively). The frequencies of peripapillary punctate choroidal hyperfluorescence and hypofluorescent patches corresponding to the areas of exudative retinal detachment were less in the eyes that developed SGF (p = 0.019; p = 0.003, respectively). Punctate choroidal hyperfluorescence elsewhere was less frequent in the eyes that developed SGF (p < 0.001) and eyes that progressed to chronic recurrent evolution (p = 0.002). CONCLUSIONS: Pretreatment ICGA has a prognostic value in initial-onset acute uveitis associated with VKH disease.

The impact of the COVID-19 pandemic on the prevalence of computer vision syndrome among medical students in Riyadh, Saudi Arabia.

PURPOSE: To estimate the prevalence of computer vision syndrome (CVS) among university medical students in Riyadh, Saudi Arabia, after establishing remote learning during COVID-19 pandemic and to compare settings of electronic device usage and patterns of CVS protective measures applied by students before and during this pandemic. METHODS: This is an observational descriptive cross-sectional study which included 1st to 5th year medical students who were actively enrolled at the governmental colleges of medicine in Riyadh, Saudi Arabia, during the COVID-19 lockdown. The sample size was estimated to be 287 medical students. Participants were asked to volunteer and fill an electronic online questionnaire. RESULTS: A total of 300 medical students were included in this study. 94.0% reported at least one symptom of CVS, while 67% reported having more than three symptoms. The most frequently reported symptoms were musculoskeletal pain (84.3%), headache (71.1%) and dry eyes (68%). Thirty-eight percent of the students experienced more severe symptoms, while 48% experienced more frequent symptoms during the COVID-19 pandemic. Risk factors for having three or more symptoms were being a female (p < 0.001) and using electronic devices for longer periods (6.8 h ± 2.8) during COVID-19 lockdown (p < 0.001). CONCLUSION: CVS prevalence during COVID-19 era among medical students is high. This necessitates increasing the awareness of CVS and its preventive measures.

Anti-vascular endothelial growth factor therapy in retinopathy of prematurity: An updated literature review.

Laser photocoagulation can still be considered the gold standard for treatment for retinopathy of prematurity (ROP). However, anti-vascular endothelial growth factor (anti-VEGF) therapy has increasingly become an important option that plays a significant role in the treatment of ROP. Major clinical trials have been published regarding the anti-VEGF use in ROP, along with multiple other studies looking into the different agents, doses, techniques, and possible complications. Anti-VEGF therapies can be considered as a safe and effective option for managing ROP. More longitudinal randomized clinical trials are necessary to evaluate the preferred treatment agent, the appropriate dose, best follow-up protocol, and the long-term ocular and systemic outcomes following treatment.

Frequency and Risk Factors of Unplanned 30-Day Readmission After Open Heart Surgeries: A Retrospective Study in a Tertiary Care Center.

BACKGROUND: Unplanned 30-day readmission post-cardiac surgery imposes higher risks for complications, increased costs, and unfavorable events for the care provider and patient. This study was to determine the unplanned readmission rate, determinants, and most common events within 30 days post-cardiac surgery. Recommendations to prevent or minimize these complications are included. METHODS: Setting and design - a retrospective record review was conducted among all adult patients, who underwent open heart surgery between 2010 and 2020 at King Abdulaziz University Hospital (KAUH), Jeddah, Kingdom of Saudi Arabia. Using Google Forms, we manually collected data from hospital records. STATISTICAL ANALYSIS USED: binomial logistic regression model (using the backward stepwise method). Regression outcomes were expressed as odds ratios (ORs) and 95% CIs. A P-value of < 0.05 indicated statistical significance. RESULTS: Among 400 patients who underwent cardiac surgery, 343 patients were included in the study, including 53 unplanned readmissions, which was a rate of 16.3% (95% CI, 12.8 to 20.6%). The most frequently reported reasons for readmission were sternal wound infections (7.3%), pleural effusion (2.0%), and heart failure (1.7%). Female gender, high postoperative LDH and urea were the most important risk factors. CONCLUSION: Discharge planning, patient education, and cardiac surgery nurse home visit constitute the most important factors to minimize 30 days of unplanned readmission.

Seizure following general anesthesia for cystoscopy and urethral dilatation: A case report.

Seizure and anesthesia is a topic necessitating more studies to understand its mechanism. Some anesthetic agents triggers seizures, while others can control it. We are here reporting a case of apparently healthy young adult patient who underwent diagnostic cystoscopy and urethral dilatation under general anesthesia and who developed seizure immediately after admission to the postanaesthetic care unit.

Physical exercise keeps the brain connected by increasing white matter integrity in healthy controls.

ABSTRACT: Physical exercise leads to structural changes in the brain. However, it is unclear whether the initiation or continuous practice of physical exercise causes this effect and whether brain connectivity benefits from exercise. We examined the effect of 6 months of exercise on the brain in participants who exercise regularly (n = 25) and in matched healthy controls (n = 20). Diffusion tensor imaging brain scans were obtained from both groups. Our findings demonstrate that regular physical exercise significantly increases the integrity of white matter fiber tracts, especially those related to frontal function. This implies that exercise improves brain connectivity in healthy individuals, which has important implications for understanding the effect of fitness programs on the brains of healthy subjects.

Clinical Approach to Linear Hyperpigmentation: A Review Article.

Linear hyperpigmentation is an unusual anatomical configuration in clinical dermatology. Owing to its rarity, consensus on the most effective method of classification is lacking. While linear hyperpigmentation generally follows Blaschko's lines, this is not universal. Clinical findings such as adherence to Blaschko's lines, associated morphological findings (including other cutaneous lesions), and systemic manifestations can be used to further characterize and diagnose variants of the disorder. Early detection of any underlying disease is vital, especially in cases with effective management, because the disorder may make it difficult to manage hyperpigmentation. Herein, we introduce a logical clinical diagnostic approach that represents a useful tool for dermatologists to efficiently evaluate patients presenting with linear hyperpigmentation. A simplified systematic and evidence-based approach is useful for this clinical condition owing to the heterogeneous causes and lack of specific diagnostic tools.

Indocyanine green angiographic findings in presumed intraocular tuberculosis.

PURPOSE: To study features of Indocyanine green angiography (ICGA) in patients with presumed intraocular tuberculosis. METHODS: Retrospective study of 48 consecutive patients (77 eyes) who underwent ICGA. The following signs were analysed: choroidal perfusion inhomogeneity, early hyperfluorescent stromal vessels, round or oval hypofluorescent dark dots (HDDs), hypofluorescent geographic lesions (HGLs), fuzzy or lost pattern of large stromal choroidal vessels, disc hyperfluorescence and diffuse late choroidal hyperfluorescence. RESULTS: Among 44 eyes of 29 patients with no clinical evidence of choroidal involvement, only 7 eyes of 6 patients had no ICGA evidence of choroidal involvement. On the other hand, ICGA findings suggesting choroidal involvement were noted in 37 (84.1%) eyes of 23 patients in the form of HDDs in all 37 (100%) eyes, HGLs in 7 (18.9%) eyes, disc hyperfluorescence in 20 (45.5%) eyes, fuzzy stromal vessels in 17 (38.6%) eyes, early hyperfluorescent stromal vessels in 13 (29.5%) eyes, late pinpoint hyperfluorescence in 11 (25%) eyes and late diffuse choroidal hyperfluorescence in 7 (15.9%) eyes. Among 33 eyes of 19 patients with clinically evident choroidal involvement, the following findings were identified; HDDs in 12 (36.4%) eyes, HGLs in 10 (30.3%) eyes, both HDDs and HGLs in 9 (27.3%) eyes, disc hyperfluorescence in 11 (33.3%) eyes, early hyperfluorescent stromal vessels in 7 (21.2%) eyes, fuzzy stromal vessels in 6 (18.2%) eyes and late diffuse choroidal hyperfluorescence was present in 2 (6.1%) eyes. CONCLUSIONS: ICGA is necessary in identifying and diagnosing subclinical tuberculous choroidal involvement. The most prevalent ICGA finding was persistent HDDs.

Effects of transcranial direct current stimulation over frontal, parietal and cerebellar cortex for cognitive function during fasting in healthy adults.

BACKGROUND: Transcranial direct current stimulation (tDCS) is a neuromodulation tool used to modify the cognitive function in subjects. There is a paucity of data on tDCS' effect on cognitive function during Ramadan fasting. This paper aims to assess the effect of tDCS of three brain areas, including the right dorsolateral prefrontal cortex (DLPFC), posterior parietal cortex (PPC), and cerebellum on cognitive function, and obtain safety data in healthy adults during Ramadan fasting. METHODS AND MATERIAL: A total of 42 healthy, right-handed participants were randomly assigned to one of the 6 stimulation groups: active (anodal)-tDCS of right DLPFC, PPC, and cerebellum; or sham for DLPFC, PPC, and cerebellum after 8 h of fasting for Ramadan. Safety data and cognitive function, such as attention-switching tasks (AST), were obtained by employing the Cambridge Neuropsychological Test Automated Battery (CANTAB) before and after each tDCS session. The cognitive function outcome variables were the response time and the percentage of correct answers in AST. For sham stimulation, the placement of the electrodes was the same as for the active stimulation. RESULTS: An improvement in performance time in attention tasks was observed; however, it did not reach a significant level after anodal stimulation of the DLPFC, PPC, and cerebellum. Overall, there were no statistically significant differences between the active and sham tDCS groups in cognitive function. There were no significant side effects of tDCS during fasting for any group. CONCLUSIONS: Our data suggest that there are variable effects of tDCS on attention tasks during Ramadan fasting. TDCS appears to be safe, well-tolerated and adhered to the international standard of safety in the local population during Ramadan fasting. Further large sample size studies should be conducted to validate the current study findings and reach better conclusions.

Health-related quality of life and its associated factors among patients with angina in Jordan.

BACKGROUND: Despite the negative impact of angina and its worsening symptoms on the quality of life of the affected patients, little research has evaluated the factors associated with poor health-related quality of life (HRQOL) among patients with angina. OBJECTIVE: The study aim was to evaluate HRQOL and to explore factors associated with poor HRQOL in patients with angina in Jordan. SETTING: The present study used data collected for patients attending the cardiology clinic at the Royal Medical Services (RMS) Hospital in Amman. METHODS: In addition to collecting sociodemographic and clinical data, the EQ-5D questionnaire was used to assess HRQOL in outpatients with angina in the present study. Multiple linear regression analysis was conducted to build a model with variables that are significantly and independently associated with poor HRQOL. MAIN OUTCOME MEASURE: HRQOL quantified using the EQ-5D. RESULTS: The mean of the total EQ-5D score of the 500 participants was 0.392. Most of the patients reported 'some problems' through the five dimensions, with the highest percentage (66.6%) related to mobility domain. Regression analysis identified female gender (B = - 0.232; P < 0.05) elevated fasting blood sugar (FBS) (P < 0.05; B = - 0.219), and low high density lipoprotein (HDL) (B = - 0.183; P < 0.05) as being significantly associated with poor HRQOL. CONCLUSIONS: The HRQOL has considerable scope for improvement for patients with angina in Jordan. Female gender, elevated FBS, and decreased HDL levels were significantly associated with poor HRQoL in the present study.

Knowledge and awareness of plantar fasciitis in the Saudi population.

OBJECTIVE: To evaluate and assess the knowledge and awareness level of lay people about plantar fasciitis (PF). METHODS: The cross-sectional study was conducted at a shopping mall in Riyadh, Saudi Arabia, from May to July 2017, and comprised random individuals busy shopping in the area. Data was collected through a self-administered questionnaire. , and was analysed using SPSS 22. . RESULTS: Of the 176 subjects, 101(57.4%) were females and 75(42.6%) were males. The age range was 18-55 years, and 153(87%) belonged to urban population. Overall, 60(34%) subjects had never heard of plantar fasciitis. Also, 148(84%) subjects thought that specialised medical shoes can be used as possible treatment for plantar fasciitis (p<0.001).Females had significantly higher knowledge regarding plantar fasciitis than males (p=0.009). CONCLUSIONS: Over 30% subjects did not have any knowledge about plantar fasciitis.

Postpartum Endogenous Candida Endophthalmitis.

Postpartum endogenous fungal endophthalmitis in otherwise healthy females is extremely rare disease. We report a case of a 25-year-old female patient referred with a history of decreased vision in her right eye 1 month after uncomplicated vaginal delivery. She presented with multifocal chorioretinal infiltrates. The patient showed persistent inflammation in her right eye then after. Systemic workup was unremarkable apart from a history of vaginal discharge during peripartum period. Vaginal swap confirmed the presence of Candida albicans. Culture of the vitreous sample confirmed the growth of C. albicans. The patient was managed with intravitreal amphotericin B in addition to systemic antifungal treatment followed by pars plana vitrectomy. The patient achieved 20/40 vision with quiet eye after 6 months of follow-up.

Presumed tuberculous uveitis in a university-based tertiary referral center in Saudi Arabia.

PURPOSE: To describe clinical characteristics and outcomes of treatment in patients with presumed tuberculous uveitis (PTU). METHODS: All patients diagnosed with PTU between January 1996 and March 2013 were reviewed. The diagnosis was made when clinical findings were consistent with possible intraocular tuberculosis, strongly positive purified protein derivative (PPD) skin test result, and response to anti-tuberculous therapy with no other cause of uveitis as suggested by history, symptoms, or ancillary testing. RESULTS: Ninety patients (141 eyes) were identified. There were 43 males (47.3%) and 47 females (52.7%). Mean age was 48.2 ± 14.4 years. Mean duration of symptoms prior to presentation was 6.7 ± 8.3 months. Ten eyes (7.1%) had anterior uveitis, 18 eyes (12.8%) had intermediate uveitis, 34 eyes (24.1%) had posterior uveitis, and 79 eyes (56%) had panuveitis. Macular edema was present in 33.3% of the eyes at presentation. All patients received anti-tuberculous therapy and systemic corticosteroids. Mean follow-up after completion of therapy was 36 ± 2.5 months. Only 2 eyes developed recurrent inflammation after treatment completion. At last follow-up, all eyes showed resolution of inflammation, associated with significant improvement in visual acuity. There was a significant positive correlation between initial and final VA. Eyes that had macular edema at presentation showed a significant reduction in central macular thickness at final follow-up. CONCLUSIONS: There is delay in presentation of patients with PTU. The most common anatomic diagnosis was panuveitis. Treatment with anti-tuberculous therapy combined with systemic corticosteroids resulted in resolution of inflammation and macular edema with significant improvement in visual acuity.

Safety of Transcranial Direct Current Stimulation of Frontal, Parietal, and Cerebellar Regions in Fasting Healthy Adults.

(1) Background: Transcranial direct current stimulation (tDCS) is a non-invasive brain stimulation modality that has been investigated in a large number of studies in terms of it is effects on brain function, safety of use, and future implications. The principal aim of this study was to investigate the safety of 1.5-mA tDCS of three brain areas, that is, frontal, partial, and cerebellar cortices, in fasting healthy individuals during the month of Ramadan. (2) Methods: In a single-blinded, sham-controlled study, we assessed the safety of a 20-min tDCS current (1.5 mA, 35 cm²) over the right frontal, parietal, and cerebellar cortex areas after 8 h of fasting in healthy right-handed adult subjects using a standard safety questionnaire. (3) Results: A total of 49 subjects completed the tDCS sessions and safety questionnaire. None of the sessions were stopped due to pain or discomfort during stimulation. Moreover, no subject experienced serious adverse events such as seizures or loss of consciousness. (4) Conclusions: There was no significant difference in the frequency or type of side effects between active and sham stimulation sessions. The tDCS protocol applied in this study was found to be safe in fasting healthy adults.
