“…27 Present study finds eight miners reported about low vision and six of them reported hearing loss. Low vision might be because of dust 28 or sunlight 29 because miners were exposed to dust and sunlight during work. Worldwide, 16% of the disabling hearing loss in adults is attributed to occupational noise.…”

Sandstone is one of the most common types of sedimentary rock and is found in sedimentary basins throughout the world 1 and India have an aerial extent of about 1.79 million sq. km. 2 The sandstone is composed of mineral, rock, and organic materials with varying percentage. Mineral part in sandstone is usually quartz. The quartz content of these sands can be-up to 90% or more. It is a chemical compound consisting of one part silicon and two parts oxygen called silicon dioxide (SiO 2). It is the most abundant mineral found in Earth's surface with varying colors of white, gray, purple, yellow, brown, black, pink, green and red. 1 Rapidly increasing demand for metal and minerals to meet the demand for growing infrastructure has greatly increased the importance of mining. Sandstone is one of those material used in roofing, flooring, paving, paneling, beams, pillars, arches, doors and window sills, wall facing, fence posts, milestones, etc. It is especially useful for exterior cladding in sea shore buildings due to acid & ABSTRACT Background: This study is carried out with aims to assess socioeconomic and health status of the miners in Sorya Village of Karauli district of Rajasthan, India. Mining has always been among the most hazardous of occupations and rapidly increasing demand for metal and minerals to meet the demand for growing infrastructure has greatly increased the importance of mining. The quarrying and crushing are carried out in many parts of India and majority of stone mines are unorganized. Methods: A cross sectional study was conducted among 126 miners in Sorya village, Karauli during 20 to 30 May 2014. Results: Average ages of miner were 41 and average household sizes of the miners were six. Around 80 % miners addicted to substance abuse and spend average Rs. 17 daily. Average monthly incomes of them were Rs. 3200 and 39 % has miners are in debt of more than 1 lakh. One of the reasons of debt was father died in debt and carried forward to the children. Seventy-seven percent of miners belong to lower caste and rest of them belongs to other backward class. Average BMI of miners was 19.7 kg/m 2 and 38% miner were malnourished (BMI <18.5 kg/m 2). Health problem reported by most of them were TB, silicosis, chest pain, back pain, Cough and Musculoskeletal disorder. Some of miners reported about low vision and hearing loss too. Conclusion: From the study, it can be concluded that one reason for miner's indebtedness is father carry forward. Sandstone mining leads to Silicosis, TB and body pain and musculoskeletal disorder. Large sample size studies will give a clearer picture that will helpful in policy implication for more than 2.5 million miners in Rajasthan, India.

The changes in the cardiovascular system are associated with ocular manifestations, often as a consequence of pathological alteration in the ocular vasculature. The ease of visualization of these retinal changes makes the eye a window to the cardiovascular system. Certain congenital cardiac defects lead to changes in the retinal vascularity due to increased tortuosity and dilatation. In adults, the arterial dissection of internal carotid and vertebral arteries present as amaurosis fugax with or without oculo-sympathetic palsy. The patients with untreated infective endocarditis present with Roth spots, retinitis, embolic retinopathy, or sub-retinal abscesses. Hypoperfusive, hypertensive, or “mixed” retinopathy is a hallmark sign in patients of untreated infective endocarditis. Giant cell arteritis can present with ischemic ocular symptoms that may precipitate in irreversible vision loss. Systemic vascular manifestations such as coronary artery disease may manifest in a wide range of symptoms from amaurosis fugax to vision loss depending upon the size and location of retinal emboli. Rare cardio-oncological pathologies such as myxomas result in vision loss secondary to central retinal artery occlusion. A high clinical suspicion in patients with history of cardiovascular diseases can help in early diagnosis and management of impending, adverse cardiovascular and cerebrovascular events. In this review, we comprehensively discuss the spectrum of cardiac and vascular diseases with ocular manifestations as well as highlight the typical ocular presentations associated with these pathologies.

“…1 Symptoms of ocular ischemia have been reported to occur on a hemodynamic basis also. It has been proposed that symptoms occur when relative perfusion deficits result from the combination of occlusion or stenosis of the ipsilateral internal carotid artery with a hemodynamic stress, 2-4 increased retinal oxygen demand, [5][6][7][8] or bright light amaurosis fugax associated with increased intraocular pressure. 4 Hemodynamic stressors that have been reported in association with transient visual changes include orthostasis associated with postural changes, antihypertensive therapy, or postprandial effects.…”

Mastication steal: An unusual precipitant of cerebrovascular insufficiency

An 83-year-old man had episodic dizziness, visual disturbance, and facial and extremity weakness associated with eating. Occlusion of the ipsilateral common carotid artery and stenosis or occlusion of the major collateral sources were demonstrated. We believe this anatomic configuration, combined with increases in demand for external carotid artery blood flow necessitated by the act of chewing, resulted in a vascular steal syndrome. An extended carotid endarterectomy was performed, and there were no additional episodes.
