Retinopathy of prematurity

Retinopathy of prematurity (ROP), previously known as retrolental fibroplasia (RLF), is an eye disease that affects prematurely born babies. ROP can be mild and may resolve spontaneously, but may lead to blindness in serious cases. As such, all preterm babies are at risk for ROP, and very low birth weight is an additional risk factor. Both oxygen toxicity and relative hypoxia can contribute to the development of ROP.

Supplemental oxygen exposure, while a risk factor, is not the main risk factor for development of this disease. Restricting supplemental oxygen use does not necessarily reduce the rate of ROP, and may raise the risk of other hypoxia-related systemic complications.

Patients with ROP are at greater risk for strabismus, glaucoma, cataracts and myopia later in life, and should be examined yearly to help prevent and treat these conditions.

Early treatment with erythropoietin has been show to significantly increase the risk of ROP in premature infants, and is not recommended.

The stage of ROP refers to the character of the leading edge of growing retinal blood vessels (at the vascular-avascular border). The stages of ROP disease have been defined by the International Classification of Retinopathy of Prematurity (ICROP).

Retinal examination with scleral depression is generally recommended for patients born before 30-32 weeks gestation, with birthweight 1500 grams or less, or at the discretion of the treating neonatologist.

Peripheral retinal ablation is the mainstay of ROP treatment. The destruction of the avascular retina is performed with a solid state laser photocoagulation device, as these are easily portable to the operating room or neonatal ICU. Cryotherapy, an earlier technique in which regional retinal destruction was done using a probe to freeze the desired areas, has also been evaluated in multi-center clinical trials as an effective modality for prevention and treatment of ROP. However, cryotherapy is no longer preferred for routine avascular retinal ablation in premature babies, due to the side effects of inflammation and lid swelling.

Biography of the week

Charlie Chaplin

Charlie Chaplin (1889-1977), English motion-picture actor, director, producer, and composer, one of the most creative artists in film history, who first achieved worldwide fame through his performances in silent films. His full name was Sir Charles Spencer Chaplin.

Born in London, as a child Chaplin appeared in music hall and pantomime performances. In 1910 he toured the United States with a pantomime troupe and decided to remain in the country. Chaplin first appeared on the screen in 1914 with the Keystone Film Company of American director Mack Sennett. In Kid Auto Races at Venice (1914), wearing baggy pants, enormous shoes, and a bowler hat and carrying a bamboo cane, he originated his world-famous character, the Tramp. He played this classic role in more than 70 films during his career. He was associated later with the Essanay Film Company, the Mutual Film Company, and the First National Film Company. In 1918 his own studio in Hollywood, California, was completed. During these years Chaplin gradually developed the tramp character from a jaunty, slapstick stereotype into the compassionate human figure that came to be loved by audiences throughout the world. In 1919 he helped found the United Artists Corporation, with which he was associated until 1952. Important pictures Chaplin produced, directed, and starred in include The Kid (1921), The Pilgrim (1923), The Gold Rush (1925), The Circus (1928), City Lights (1931), Modern Times (1936), The Great Dictator (1940), Monsieur Verdoux (1947), Limelight (1952), and A King in New York (1957). Chaplin wrote, directed, and played in A Countess from Hong Kong (1967). He also composed background music for most of his films.

In the late 1940s and early 1950s Chaplin was criticized for his leftist political views. As a result, he left the United States in 1952 and established permanent residence in Switzerland. In 1972 he briefly returned to the United States to receive several tributes, among them a special Academy Award for his contributions to the film industry. He was knighted in 1975.

Chaplin perfected an individual style of performing, derived from the circus clown and the mime, combining acrobatic elegance, expressive gesture, facial eloquence, and impeccable timing. His portrayal of the little tramp, a universally recognized symbol of indestructible individuality triumphing over adversity and persecution, both human and mechanical, won him critical renown as a tragicomedian. Film sound recording in the late 1920s, however, imperiled the effectiveness of the pantomime on which much of his creative imagination depended; also, he became concerned with themes of contemporary significance. In his first two films of the sound era, City Lights and Modern Times, Chaplin's little tramp remained silent. Subsequently, he abandoned the role of the tramp and relied upon specific character portrayal. The Great Dictator, which uses all the resources of sound recording, marks this transition. Chaplin's treatment of his subjects compounds satire and pathos, revealing a love of humanity and of individual freedom. He wrote My Autobiography (1964; reprinted as My Early Years,1982) and My Life in Movies (1975). Sir Richard Attenborough's biographical film Chaplin appeared in 1992.

RECOVERY PACKAGE

The recovery package has tax breaks for families that send a child to college, purchase a new car, buy a first home or make the ones they own more energy efficient.
Millions of workers can expect to see about $13 extra in their weekly paychecks, starting around June, from a new $400 tax credit to be doled out through the rest of the year. Couples would get up to $800. In 2010, the credit would be about $7.70 a week, if it is spread over the entire year.
The $1,000 child tax credit would be extended to more low-income families that don't make enough money to pay income taxes, and poor families with three or more children will get an expanded Earned Income Tax Credit.
Middle-income and wealthy taxpayers will be spared from paying theAlternative Minimum Tax, which was designed 40 years ago to make sure wealthy taxpayers pay at least some tax, but was never indexed for inflation. Congress fixes it each year, usually in the fall.
First-time homebuyers who purchase their homes before Dec. 1 would be eligible for an $8,000 tax credit, and people who buy new cars before the end of the year can write off the sales taxes.
Homeowners who add energy-efficient windows, furnaces and air conditioners can get a tax credit to cover 30 percent of the costs, up to a total of $1,500. College students — or their parents — are eligible for tax credits of up to $2,500 to help pay tuition and related expenses in 2009 and 2010.
Those receiving unemployment benefits this year wouldn't pay any federal income taxes on the first $2,400 they receive.

CALCIUM CARBIDE

Calcium carbide is a chemical compound with the chemical formula of CaC₂. The material is colorless, but most samples appear black through to grayish white lumps, depending on the grade. Its main use industrially is in the production of acetylene and calcium cyanamide.

Production

Calcium carbide is produced industrially in an electric arc furnace loaded with a mixture of lime and coke at approximately 2000 °C. This method has not changed since its invention in 1888:

CaO + 3C → CaC₂ + CO

The high temperature required for this reaction is not practically achievable by traditional combustion, so the reaction is performed in an electric arc furnace with graphite electrodes. The carbide product produced generally contains around 80% calcium carbide by weight. The carbide is crushed to produce small lumps that can range a few mm up to 50 mm. The impurities are concentrated in the finer fractions. The CaC₂ content of the product is assayed by measuring the amount of acetylene produced on hydrolysis. As an example the British and German standards for the content of the coarser fractions are 295 L/kg and 300 L/kg respectively. Impurities present in the carbide include phosphide, which produces phosphine when hydrolysed.

Crystal structure

Pure calcium carbide is a colourless solid. The common crystalline form at room temperature is a distorted rock salt structure with the C₂²⁻ units lying parallel.

Applications

Production of acetylene

The reaction of calcium carbide with water was discovered by Friedrich Wöhler in 1862.

CaC₂ + 2H₂O → C₂H₂ + Ca(OH)₂

This reaction is the basis of the industrial manufacture of acetylene, and is the major industrial use of calcium carbide. In China, acetylene derived from calcium carbide remains a feedstock for the chemical industry, in particular for the production of polyvinyl chloride, PVC.

Production of calcium cyanamide

Calcium carbide reacts with nitrogen at high temperature to form calcium cyanamide:

CaC₂ + N₂ → CaCN₂ + C

Calcium cyanamide is used as fertilizer. It is hydrolysed to cyanamide, H₂NCN.

Steelmaking

Calcium carbide is used:

• in the desulfurisation of iron (pig iron, cast iron and steel)
• as a fuel in steelmaking to extend the scrap ratio to liquid iron depending on economics.
• as a powerful deoxidizer at ladle treatment facilities.
