Air pollution: Health effects / contaminación del aire: efectos en la salud

Abstract Background: Air contamination happens when unsafe or inordinate amounts of substances including gases, particles, and organic atoms are brought into Earth's climate. Objective: This review article defines air pollution, describes the types of pollutants, enumerates the various causative factors, enumerates the ways it impacts human health and suggests preventive measures to reduce the impact of air pollution on human health. Methods: Literature was studied extensively and effects of air pollution on human health have been described. Results and Conclusion: Air pollution has tremendous effects on human health in the form of respiratory diseases and aggravations in the form of asthma and lung cancer, cardiovascular dysfunctions, and malignant growth. An affiliation has been found to exist between male infertility and air pollution and a relationship has been established between air contamination and higher danger of immune dysfunction, neuroinflammation, neurobehavioral hyperactivity, crime, age-unseemly behaviours, Alzheimer's and Parkinson's disease. Traffic-related air pollutants have been found to affect skin aging and cause pigmented spots on the face. An association exists between air pollution and irritation of the eyes, dry eye syndrome, risk for retinopathy and adverse ocular outcomes. Chronic exposure to air pollutants during pregnancy has been associated with adverse effects on the developing foetus in the form of low birth weight and still birth. Air contamination has been seen as a significant supporter of the expanded predominance of allergic diseases in children.

A case of elbow dislocation / Un caso de dislocación de codo

Abstract The elbow joint is a stable joint and a significant force is required to disrupt the joint. The elbow joint is the second most commonly dislocated joint. A 29 years old male sustained a fall on outstretched hand and presented with pain, swelling , deformity and inability to move his Right elbow. Closed Reduction was done followed by immobilisation for 3 weeks and thereafter range of movement exercises of the elbow joint. Neurovascular complications , associated fracture around the elbow joint and instability of the joint should be looked for. Associated fractures which are difficult to see on plain X Rays can go for Computerized tomography and unstable fractures where damage to the ligamentous complex is suspected should undergo an Magnetic Resonance imaging study of the involved joint.
