Hand–arm Vibration Syndrome
Vibration white finger (VWF), also known as hand-arm vibration syndrome (HAVS) or dead finger, is a secondary form of Raynaud's syndrome, an industrial injury triggered by continuous use of vibrating hand-held machinery. Use of the term ''vibration white finger'' has generally been superseded in professional usage by broader concept of HAVS, although it is still used by the general public. The symptoms of vibration white finger are the vascular component of HAVS. HAVS is a widespread recognized industrial disease affecting tens of thousands of workers. It is a disorder that affects the blood vessels, nerves, muscles, and joints of the hand, wrist, and arm. Its best known effect is vibration-induced white finger (VWF), a term introduced by the Industrial Injury Advisory Council in 1970. Injury can occur at frequencies between 5 and 2000 Hz but the greatest risk for fingers is between 50 and 300 Hz. The total risk exposure for hand and arm is calculated by the use of ISO 534 ...

Raynaud's Syndrome
Raynaud syndrome, also known as Raynaud's phenomenon, eponymously named after the physician Auguste Gabriel Maurice Raynaud, who first described it in his doctoral thesis in 1862, is a medical condition in which the spasm of small arteries causes episodes of reduced blood flow to end arterioles. Typically, the fingers, and less commonly, the toes, are involved. Rarely, the nose, ears, or lips are affected. The episodes classically result in the affected part turning white and then blue. Often, numbness or pain occurs. As blood flow returns, the area turns red and burns. The episodes typically last minutes but can last several hours. Episodes are typically triggered by cold or emotional stress. Primary Raynaud's, also known as idiopathic, means that it is spontaneous, of unknown cause, and unrelated to another disease. Secondary Raynaud's occurs as a result of another condition and has an older age at onset; episodes are intensely painful and can be asymmetric and associated wi ...

Lawsuits
- A lawsuit is a proceeding by a party or parties against another in the civil court of law. The archaic term "suit in law" is found in only a small number of laws still in effect today. The term "lawsuit" is used in reference to a civil action brought by a plaintiff (a party who claims to have incurred loss as a result of a defendant's actions) requests a legal remedy or equitable remedy from a court. The defendant is required to respond to the plaintiff's complaint. If the plaintiff is successful, judgment is in the plaintiff's favor, and a variety of court orders may be issued to enforce a right, award damages, or impose a temporary or permanent injunction to prevent an act or compel an act. A declaratory judgment may be issued to prevent future legal disputes. A lawsuit may involve dispute resolution of private law issues between individuals, business entities or non-profit organizations. A lawsuit may also enable the state to be treated as if it were a private party in a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tort Law
A tort is a civil wrong that causes a claimant to suffer loss or harm, resulting in legal liability for the person who commits the tortious act. Tort law can be contrasted with criminal law, which deals with criminal wrongs that are punishable by the state. While criminal law aims to punish individuals who commit crimes, tort law aims to compensate individuals who suffer harm as a result of the actions of others. Some wrongful acts, such as assault and battery, can result in both a civil lawsuit and a criminal prosecution in countries where the civil and criminal legal systems are separate. Tort law may also be contrasted with contract law, which provides civil remedies after breach of a duty that arises from a contract. Obligations in both tort and criminal law are more fundamental and are imposed regardless of whether the parties have a contract. While tort law in civil law jurisdictions largely derives from Roman law, common law jurisdictions derive their tort law from cus ...

Overuse Injuries
A repetitive strain injury (RSI) is an injury to part of the musculoskeletal or nervous system caused by repetitive use, vibrations, compression or long periods in a fixed position. Other common names include repetitive stress disorders, cumulative trauma disorders (CTDs), and overuse syndrome. Signs and symptoms Some examples of symptoms experienced by patients with RSI are aching, pulsing pain, tingling and extremity weakness, initially presenting with intermittent discomfort and then with a higher degree of frequency. Definition Repetitive strain injury (RSI) and associative trauma orders are umbrella terms used to refer to several discrete conditions that can be associated with repetitive tasks, forceful exertions, vibrations, mechanical compression, sustained or awkward positions, or repetitive eccentric contractions. The exact terminology is controversial, but the terms now used by the United States Department of Labor and the National Institute of Occupational Safe ...

Hypothenar Hammer Syndrome
Hypothenar hammer syndrome (HHS) is a vascular occlusion in humans in the region of the ulna. It is caused by repetitive trauma to the hand or wrist (such as that caused by the use of a hammer) by the vulnerable portion of the ulnar artery as it passes over the hamate bone, which may result in thrombosis, irregularity or aneurysm formation. HHS is a potentially curable cause of Raynaud's syndrome, distinct from hand–arm vibration syndrome. Cause Diagnosis A physical examination of the hand may show discoloration (blanching, mottling, and/ or cyanosis; gangrene may be present in advanced cases), unusual tenderness/ a callous over the hypothenar eminence, and fingertip ulcerations and splinter hemorrhages over ulnar digits; if an aneurysm is present, there may also be a pulsatile mass. Allen's test will be positive if an occlusion is present and negative if an aneurysm is present. An angiogram may show a "corkscrew" ulnar artery or an occlusion or aneurysm at the hook of the hama ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Cutaneous Conditions
Many skin conditions affect the human integumentary system—the organ system covering the entire surface of the body and composed of skin, hair, nails, and related muscle and glands. The major function of this system is as a barrier against the external environment. The skin weighs an average of four kilograms, covers an area of two square metres, and is made of three distinct layers: the epidermis, dermis, and subcutaneous tissue. The two main types of human skin are: glabrous skin, the hairless skin on the palms and soles (also referred to as the "palmoplantar" surfaces), and hair-bearing skin.Burns, Tony; ''et al''. (2006) ''Rook's Textbook of Dermatology CD-ROM''. Wiley-Blackwell. . Within the latter type, the hairs occur in structures called pilosebaceous units, each with hair follicle, sebaceous gland, and associated arrector pili muscle. In the embryo, the epidermis, hair, and glands form from the ectoderm, which is chemically influenced by the underlying mesoderm th ...

Coal Miners
People have worked as coal miners for centuries, but they became increasingly important during the Industrial revolution when coal was burnt on a large scale to fuel stationary and locomotive engines and heat buildings. Owing to coal's strategic role as a primary fuel, coal miners have figured strongly in labor and political movements since that time. After the late 19th-century coal miners in many countries were a frequent presence in industrial disputes with both the management and government. Coal miners' politics, while complex, has occasionally been radical, with a frequent leaning towards far-left political views. A number of far-left political movements have had the support of both coal miners themselves and their trade unions, particularly in Great Britain. In France, on the other hand, coal miners have been much more conservative. In India, Coal Miners Day is celebrated on May 4. Radicalism From the mid-19th century onward, coal miners have often built strong connections ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alice Hamilton
Alice Hamilton (February 27, 1869Corn, JHamilton, Alice''American National Biography'' – September 22, 1970) was an American physician, research scientist, and author. She was a leading expert in the field of occupational health and a pioneer in the field of industrial toxicology. Hamilton trained at the University of Michigan Medical School. She became a professor of pathology at the Woman's Medical School of Northwestern University in 1897. In 1919, she became the first woman appointed to the faculty of Harvard University. Her scientific research focused on the study of occupational illnesses and the dangerous effects of industrial metals and chemical compounds. In addition to her scientific work, Hamilton was a social-welfare reformer, humanitarian, peace activist, and a resident-volunteer at Hull House in Chicago from 1887 to 1919. She received numerous honors and awards, including the Albert Lasker Public Service Award. Early life and family Hamilton, the second chil ...

Chainsaw Safety Features
This article is about risk control methods specific to chainsaws and chainsaw operations. Chainsaws incorporate numerous safety features common to many engine-driven power tools. Manufacturers have invented numerous design features to improve safety. Some features have become ''de facto'' standards, and others are legal requirements in particular jurisdictions. Best practice dictates that an operator should inspect the saw before starting work and only operate the saw if all the safety features are properly functional. Additional safety features are a significant commercial advantage to chainsaw producers. Companies continue to develop new features over time. Most chainsaw safety features are focused on the kickback problem, and seek to either avoid it (chain and bar design), or to reduce the risk of injury should it occur ( chain brakes). In addition to the safety features built into the chainsaw, operators should also wear specific chainsaw safety clothing. Most older saws ha ...

NIOSH Power Tools Database
The NIOSH Power Tools Database contains sound power levels, sound pressure levels, and vibrations data for a variety of common power tools that have been tested by researchers. Data are collected for both the unloaded and loaded use of power tools. The database was created by the National Institute for Occupational Safety and Health (NIOSH). Purpose This database was created in order to provide information to the general public about the sound and vibrations generated by power tools during their use. Many of these tools produce sound levels high enough to damage hearing if precautions are not taken. Since this information was not readily available in most cases, NIOSH created the Power Tools Database and ran tests on power tools to provide the information. According to NIOSH, the Power Tools Database "is particularly helpful in determining the 'real-world' noise level of power tools as they are used on the job." The database is a part of the much larger Hearing Loss Prevention Re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Industrial Injury
An occupational injury is bodily damage resulting from working. The most common organs involved are the spine, hands, the head, lungs, eyes, skeleton, and skin. Occupational injuries can result from exposure to occupational hazards (physical, chemical, biological, or psychosocial), such as temperature, noise, insect or animal bites, blood-borne pathogens, aerosols, hazardous chemicals, radiation, and occupational burnout. While many prevention methods are set in place, injuries may still occur due to poor ergonomics, manual handling of heavy loads, misuse or failure of equipment, exposure to general hazards, and inadequate safety training. Worldwide It has been estimated that worldwide there are more than 350,000 workplace fatalities and more than 270 million workplace injuries annually. In 2000 there were approximately 2.9 billion workers worldwide. Occupational injuries resulted in the loss of 3.5 years of healthy life for every 1,000 workers. 300,000 of the occupational i ...
