In this case report, we describe the clinical features and treatment outcomes of bilateral optic neuritis developing after the administration of the first dose ChAdOx1_nCoV-19 (Covishield) vaccine in a previously healthy young immunocompetent male. Case report A 35-year-old healthy male, presented with sudden decrease in vision which was progressive in nature. The symptoms developed two days following the first dose of the Covid ChAdOx1_nCoV-19 vaccine. A possible diagnosis of vaccine associated optic neuritis was based on the temporal association between the administration of vaccine and the development of ocular symptoms and ruling out other immune or infectious etiologies. The patient showed good response to pulse systemic steroids followed by a short course of oral steroids. Bilateral optic nerve involvement with disc edema may represent a rare adverse event of covid 19 vaccine which responds well to a short course of steroids. [ABSTRACT FROM AUTHOR]

Purpose: To report ocular findings in a case of atypical fulminant SSPE Case report: A 20-year-old male who came with macular necrotising retinitis in both his eyes in absence of any neurological feature. Within a week the patient developed dystonic posturing and seizures. CSF examination revealed raised measles antibody titres and EEG was suggestive of SSPE. The patient succumbed to the disease within 35 days of presentation. Conclusion: SSPE can rarely have a rapidly progressive downhill course without typical neurological features and ophthalmic features which appear to be more consistent may help in clinching the diagnosis in these cases.

To report a case of bilateral ocular tuberculosis (OTB) in a child with negative Tuberculin skin test (TST). Case report. A 12-year-old malnourished systemically asymptomatic boy presented with sudden profound loss of vision in both eyes. Dense vitritis precluded fundus visualization in right eye (RE). In left eye, fundus findings of extensive vasculitis associated with multifocal retinochoroiditis were suggestive of OTB. However, negative TST, normal chest X-ray, and gram negative bacteriuria led to confusion between endogenous endophthalmitis and OTB. Based on strong clinical suspicion and high-resolution chest tomography (HRCT) of thorax which was suggestive of TB-pneumonitis, a diagnosis of presumed OTB was made. A good response to anti-tubercular-treatment and corticosteroids, with resolution of retinochoroiditis lesions, vasculitis, and vitritis, further supported our diagnosis. This case highlights the importance of keeping a high index of suspicion for TB-associated uveitis in children, based on clinical findings. [ABSTRACT FROM AUTHOR]

To report a case of herpes simplex virus retinitis following ChadOx1 nCoV-19 (covishield) vaccination. A 29 year old immunocompetent male presented with unilateral disc edema with adjacent retinitis two days after receiving the first dose of ChAdOx1 nCoV-19 vaccination. Extensive investigations to rule out infective etiology were negative except for polymerase chain reaction (PCR) of the vitreous specimen which was positive for the herpes simplex virus. A diagnosis of herpes simplex (HSV) retinitis post covid vaccination was made. The patient responded well to oral antivirals and steroids. HSV retinitis is a rare complication following the COVID-19 vaccination. [ABSTRACT FROM AUTHOR]

Bisphenol-A (BPA) is a common environmental toxin which alters testicular function in both animals and humans. BPA exerts its cytotoxic potential by altering mitochondrial oxidative stress and functioning. Therefore, protecting mitochondria from oxidative stress may prevent BPA-induced testicular damage. In the present study, modulation of BPA toxicity by mitochondria-targeted antioxidant, mito-TEMPO was studied in male Wistar rats. Rats were administered mito-TEMPO (0.1 mg/kg b.w, i.p.) twice a week, followed by BPA (10 mg/kg b.w., orally) once a week for 4 weeks. After 4 weeks, sperm parameters were evaluated in the testis along with histopathological analysis. The mitochondrial oxidative stress, mitochondrial membrane potential (MMP) and enzymatic activity of mitochondrial complex II and IV were estimated in the testicular tissue. Pretreatment of mito-TEMPO protected animals from toxic effects of BPA as indicated by the normalization of sperm parameters and preserved histoarchitecture of testis. BPA treatment to animals significantly increased mitochondrial reactive oxygen species (ROS) and lipid peroxidation (LPO). A significant decrease in the activity of mitochondrial complex II was also observed after BPA exposure whereas, mitochondrial complex II activity was increased. In addition, an increase in MMP was also observed in BPA group. Mito-TEMPO successfully normalized mitochondrial ROS and LPO formation. Similar normalization effect was also noted in the activity of mitochondrial complex II, complex IV, and MMP. Results suggested that mito-TEMPO pretreatment significantly protected BPA-induced oxidative stress and thereby mito-TEMPO effectively prevented testicular damage. [ABSTRACT FROM AUTHOR]

To report the clinical profile, outcomes of early vitrectomy for cluster endophthalmitis developing after intravitreal Bevacizumab (IVB), and discuss the role of prophylactic intracameral moxifloxacin for eyes undergoing combined cataract surgery with IVB. Single center, retrospective analysis of 35 consecutive eyes developing post-IVB inflammation. Of the 35 eyes that were administered IVB (27 eyes 'IVB alone' and 8 eyes 'IVB with cataract surgery'). Endophthalmitis developed in 28 eyes, 6 eyes were managed with Intravitreal antibiotic (IVAB) alone, while 22 eyes required early vitrectomy. Only one eye undergoing a combined phacoemulsification with IVB developed endophthalmitis. Majority(26/28) of the eyes achieved visual acuity equal to/greater than pre-IVB injection vision over a period of 3.15 ± 3.2 months. Early detection and prompt PPV were effectual for achieving good functional outcomes in our cluster of post-IVB Klebsiella endophthalmitis. Intracameral moxifloxacin was protective in cases undergoing combined cataract surgery with IVB. [ABSTRACT FROM AUTHOR]

AbstractPurposeMaterials and MethodsResultsConclusion\nIMPLICATIONS FOR REHABILITATIONTo understand the oral health attitudes, knowledge, and practices among non-dental professionals caring for patients with spinal cord injuries, as well as the barriers and facilitators to oral care across acute and rehabilitation hospital settings.This study was a descriptive qualitative study. Nine focus groups with spinal cord injury clinicians from two Sydney hospitals were conducted (n = 35). A thematic analysis was undertaken.Four themes were constructed: understanding the impact of spinal cord injuries on oral health and wellbeing; limited support in the spinal cord injury unit to promote oral care; strategies that enable oral care promotion; and recommendations to expand scope in oral care and education. Although most clinicians considered oral health to be important there was a lack of guidelines to support standardised oral care practices. Barriers included lack of time, limited oral care resources, low priority and difficulty in accessing treatment. Staff were receptive to an integrated, multidisciplinary approach to oral care.This Australian first study provides insight into spinal cord injury clinicians’ knowledge and practices of oral care. The findings will help guide future research in developing appropriate models of care to promote oral health among patients with spinal cord injuries.Individuals with a spinal cord injury are at an increased risk of irregular oral hygiene practices and poor oral health compared to those without a spinal cord injuryProviding access to training and development of a model of care for oral health promotion to support non-dental health professionals working with individuals with a spinal cord injury can improve access to early intervention oral health careImplementing targeted training for staff, developing clear guidelines or protocols, and piloting an integrated multidisciplinary model of care could be potential future solutions to close this gap in care.Individuals with a spinal cord injury are at an increased risk of irregular oral hygiene practices and poor oral health compared to those without a spinal cord injuryProviding access to training and development of a model of care for oral health promotion to support non-dental health professionals working with individuals with a spinal cord injury can improve access to early intervention oral health careImplementing targeted training for staff, developing clear guidelines or protocols, and piloting an integrated multidisciplinary model of care could be potential future solutions to close this gap in care.
