Pattern and clinical profile of patients with ocular trauma presenting to the emergency department of a teaching hospital in India: A prospective observational study.

OBJECTIVES: One major contributor to avoidable ocular morbidity is ocular trauma (OT). The study aimed to document the epidemiological factors, pattern of injury, and outcome among patients with OT presenting to the emergency department (ED). METHODS: This was a prospective observational study conducted in the ED of a tertiary care teaching hospital in Eastern India after due approval from the institutional ethics committee. The data were collected during the period from March 2021 to February 2022. Data pertaining to age, sex, type of injury, mechanism of injury, time and place of injury, details of tissue involvement, visual acuity, any prior history of injury, initial diagnosis, and management were noted. To estimate the severity of the injury and the probable visual outcome, we calculated through OT score (OTS), including one raw score and OTS. Statistical analysis was performed using the R, version 4.6.1. RESULTS: A total of 180 patient's data were included for final analysis. The median (interquartile range) age of the patients was 32 (24-45) years. The majority were males (n = 147 [81.6%]) with a male-female ratio of 4.5:1. Road traffic accidents (RTA) were the common cause of injury (n = 122 [67.7%]). Unilateral eye involvement was the most common (n = 147 [81.6%]). In the pattern of injury, most of the patients sustained closed globe injuries (CGIs) (n = 158 [87.7%]). Among the CGIs, injury to the ocular adnexa and conjunctiva (n = 141 and 127, respectively) was the most common. Injury to the retina and choroids occurred in 20 (11%) patients. The vision was not affected in most of the cases (n = 125 [69.4%]) with a visual acuity of > 6/18. The majority (n = 120 [67%]) of the patients had an OTS of grade-4, followed by grade-2 (n = 22 [12%]). Most of the patients required only medical management (n = 100 [56%]), whereas 77 (43%) patients required surgical interventions. CONCLUSION: OT was a common presentation in the ED. Male patients with monocular injuries involved in RTAs were mostly affected. The vision was preserved in most of the cases.

Ultrasound-guided selective peripheral nerve block for the snakebite pain management in the emergency department: Our experience.

Envenomation from snakebites (SBs) is a significant public health hazard globally. The venomous SB is associated with moderate-to-severe pain. Weak opioids such as tramadol or acetaminophen are commonly used for pain management but often provide inadequate analgesia. We hereby report our experience of using ultrasound-guided selective superficial peroneal, sural, and saphenous nerve blocks for pain management following SBs in nine patients. The selective peripheral nerve blocks are achieved with a small amount of local anesthesia and without loss of motor functions.

APOE ε2-Carriers Are Associated with an Increased Risk of Primary Angle-Closure Glaucoma in Patients of Saudi Origin.

This study investigated the association between apolipoprotein E (APOE) gene polymorphisms (rs429358 and rs7412) and primary angle-closure glaucoma (PACG) and pseudoexfoliation glaucoma (PXG) in a Saudi cohort. Genotyping of 437 DNA samples (251 controls, 92 PACG, 94 PXG) was conducted using PCR-based Sanger sequencing. The results showed no significant differences in the allele and genotype frequencies of rs429358 and rs7412 between the PACG/PXG cases and controls. Haplotype analysis revealed ε3 as predominant, followed by ε4 and ε2 alleles, with no significant variance in PACG/PXG. However, APOE genotype analysis indicated a significant association between ε2-carriers and PACG (odds ratio = 4.82, 95% CI 1.52-15.26, p = 0.007), whereas no notable association was observed with PXG. Logistic regression confirmed ε2-carriers as a significant predictor for PACG (p = 0.008), while age emerged as significant for PXG (p < 0.001). These findings suggest a potential role of ε2-carriers in PACG risk within the Saudi cohort. Further validation and larger-scale investigations are essential to elucidate the precise role of APOE in PACG pathogenesis and progression.

The Logistical Backbone of Photoreceptor Cell Function: Complementary Mechanisms of Dietary Vitamin A Receptors and Rhodopsin Transporters.

In this review, we outline our current understanding of the mechanisms involved in the absorption, storage, and transport of dietary vitamin A to the eye, and the trafficking of rhodopsin protein to the photoreceptor outer segments, which encompasses the logistical backbone required for photoreceptor cell function. Two key mechanisms of this process are emphasized in this manuscript: ocular and systemic vitamin A membrane transporters, and rhodopsin transporters. Understanding the complementary mechanisms responsible for the generation and proper transport of the retinylidene protein to the photoreceptor outer segment will eventually shed light on the importance of genes encoded by these proteins, and their relationship on normal visual function and in the pathophysiology of retinal degenerative diseases.

Clinico-Epidemiological Profile, Trends, and Health-Related Outcomes of Snakebite Victims: A One-Year Prospective Study from Eastern India.

INTRODUCTION: Snakebite envenomation is a significant life-threatening public health problem in Southeast Asia (SEA). In this region, India reported the largest number of snakebite deaths from 2000 to 2019 (1.2 million), with an average of 58,000 deaths yearly. METHODS: This prospective observational study was carried out among snakebite victims at the emergency department (ED) of a tertiary care public sector hospital in eastern India. RESULTS: A total of 145 cases of venomous snakebite were investigated. More than half (n = 81, 56%) of the snakebite victims were between 17 to 45 years. Most of the snakebite victims were male (68%) and were farmers (53%) by occupation. The majority of snakebites occurred during the daytime (76%) and while outdoors (67%). Most victims sustained a bite on the lower extremity (71%). The peak incidence of snakebites occurred from June to September (69%). Three-quarters of all patients were unaware of the required first aid measures following a snakebite. Among the 145 venomous snakebites, 48 were presumptively identified as the Indian cobra, 32 by the Indian krait, 56 by the Russel's viper, and 9 by saw-scaled viper. The mean duration from the snakebite to the onset of systemic effects in the Indian cobra was 52 ± 14.28 min, 66 ± 18.35 min in the Indian krait, 42 ± 13.47 min in Russel's viper, and 48 ± 16.38 min in saw-scaled viper. Respiratory failure was the commonly observed complication following an elapid envenomation. The mortality rate was 2.1% among the patients treated with antivenom. CONCLUSIONS: Snakebite is considered an occupational hazard in India, commonly affecting the young population in their productive period. The peak incidence was during monsoon season, and the majority had neurotoxic envenomation following an elapid bite (55%) that contributed to the increased mortality and morbidity among young adults. Of the 145 patients, the majority (84%) recovered fully with treatment; 16% of the victims developed morbidity viz cellulitis, respiratory failure, acute renal failure, compartment syndrome, local tissue necrosis, intracerebral hemorrhage, and disseminated intravascular coagulation. Appropriate first aid measures and timely medical intervention can significantly improve the treatment outcome following snakebites.
