Introduction toopticalmicroscopy

Our firm is well aware of these failures and more. In many cases, our clients had to deal with unnecessary delays and hardship in obtaining access to care, treatment, and certification of their 9/11 conditions. Because of LHI’s multiple failures, another contractor will be taking over in mid-2022. We are hoping that this new contractor will provide superior service but we stand ready to intervene on behalf of our clients whenever necessary as we have done through the years with LHI.

To ensure all 9/11 survivors and first responders benefit from the WTCHP – regardless of where they live – the NIOSH enlisted the help of LHI, a third-party intermediary/middleman, to process claims for individuals living outside of New York City. LHI is not an insurance company. Rather, LHI (whose parent company is OptumServe) processes claims for the WTCHP, utilizing contracted providers from throughout the country.

The World Trade Center Health Program (WTCHP) has been under fire recently following revelations identified in an NBC news story released on September 9, 2021. According to NBC, many 9/11 survivors and first responders who live outside of the New York City metropolitan area have been neglected as they seek treatment for cancer and other serious physical and mental conditions, sparking immediate action from certain lawmakers.

A large number of 9/11 survivors and first responders have experienced a worsening of their mental health conditions. Grappling with long customer service wait times (rather than the old method of speaking with one case manager) is too much for many of these brave souls to handle. Perhaps the decision to eliminate the case manager system was the beginning of the end for LHI. What 9/11 survivors and first responders need the most aside from medically necessary care is compassion and respect for what they have gone through.

Simple microscopes using single lenses can generate fine images; however, they can also produce spurious colours due to chromatic aberration, in which different wavelengths of light do not come to the same focus. The aberrations were worse in the compound microscopes of the time, because the lenses magnified the aberrations at least as much as they magnified the images. Although the compound microscopes were beautiful objects that conferred status on their owners, they produced inferior images. In 1733 the amateur English optician Chester Moor Hall found by trial and error that a combination of a convex crown-glass lens and a concave flint-glass lens could help to correct chromatic aberration in a telescope, and in 1774 Benjamin Martin of London produced a pioneering set of colour-corrected lenses for a microscope.

The appearance of new varieties of optical glasses encouraged continued development of the microscope in the 19th century, and considerable improvements were made in understanding the geometric optics of image formation. The concept of an achromatic (non-colour-distorting) microscope objective was finally introduced in 1791 by Dutch optician Francois Beeldsnijder, and the English scientist Joseph Jackson Lister in 1830 published a work describing a theoretical approach to the complete design of microscope objectives. The physics of lens construction was examined by German physicist Ernst Abbe. In 1868 he invented an apochromatic system of lenses, which had even better colour correction than achromatic lenses, and in 1873 he published a comprehensive analysis of lens theory. Light microscopes that were produced in the closing quarter of the 19th century reached the effective limits of optical microscopy. Subsequent instruments, such as phase-contrast microscopes, interference microscopes, and confocal microscopes, solved specific problems that had arisen during the study of specimens such as living cells.

The concept of magnification has long been known. About 1267 English philosopher Roger Bacon wrote in Perspectiva, “[We] may number the smallest particles of dust and sand by reason of the greatness of the angle under which we may see them,” and in 1538 Italian physician Girolamo Fracastoro wrote in Homocentrica, “If anyone should look through two spectacle glasses, one being superimposed on the other, he will see everything much larger.”

No one should have to bear the costs of battling a 9/11 cancer or illness alone. Having a lawyer by your side can help you maximize the benefits you receive, and ensure your rights are protected. Let’s talk today to see if you might be eligible for representation.

Survivors and first responders who were exposed to significant levels of toxins following the 9/11 terrorist attacks are not asking for handouts. They are not asking for money. All they want is the medical care they have already qualified for under the WTCHP. Because LHI has deteriorated over the past decade, 9/11 victims have to look elsewhere for treatment.

Only four days after the release of the NBC news story, on September 13, 2021, a bipartisan group of New York House members “summoned” the National Institute for Occupational Safety and Health (NIOSH) and Wisconsin-based Logistics Health, Inc. (LHI) to appear before the House Oversight and Reform and House Judiciary committees to field questions from concerned House members.

Three Dutch spectacle makers—Hans Jansen, his son Zacharias Jansen, and Hans Lippershey—have received credit for inventing the compound microscope about 1590. The first portrayal of a microscope was drawn about 1631 in the Netherlands. It was clearly of a compound microscope, with an eyepiece and an objective lens. This kind of instrument, which came to be made of wood and cardboard, often adorned with polished fish skin, became increasingly popular in the mid-17th century and was used by the English natural philosopher Robert Hooke to provide regular demonstrations for the new Royal Society. These demonstrations commenced in 1663, and two years later Hooke published a folio volume titled Micrographia, which introduced a wide range of microscopic views of familiar objects (fleas, lice, and nettles among them). In this book he coined the term cell.

Many 9/11 claimants have resorted to using private health insurance (if they have it) or using their own money to pay for the expensive treatment associated with cancer and other debilitating (and life-threatening) conditions. Additionally, because a large population of 9/11 survivors and first responders suffer from PTSD and anxiety, they have trouble coping – through no fault of their own – with the fact that LHI has made little to no effort to ensure these 9/11 claimants are treated respectfully and receive the care they need and deserve.

Hidden in the unnumbered pages of Micrographia’s preface is a description of how a single high-powered lens could be made into a serviceable microscope, and it was using this design that the Dutch civil servant Antonie van Leeuwenhoek began his pioneering observations of freshwater microorganisms in the 1670s. He made his postage-stamp-sized microscopes by hand, and the best of them could resolve details around 0.7 μm. His fine specimens discovered in excellent condition at the Royal Society more than three centuries later prove what a great technician he was. Using his simple microscope, Leeuwenhoek effectively launched microbiology in 1674, and single-lensed microscopes remained popular until the 1850s. In 1827 they were used by Scottish botanist Robert Brown to demonstrate the ubiquity of the cell nucleus, a term he coined in 1831.

The simple microscope consists of a single lens traditionally called a loupe. The most familiar present-day example is a reading or magnifying glass. Present-day higher-magnification lenses are often made with two glass elements that produce a colour-corrected image. They can be worn around the neck packaged in a cylindrical form that can be held in place immediately in front of the eye. These are generally referred to as eye loupes or jewelers’ lenses. The traditional simple microscope was made with a single magnifying lens, which was often of sufficient optical quality to allow the study of microscopical organisms including Hydra and protists.

The NBC News investigation into LHI documents horrific details that have caused unnecessary stress and harm to many 9/11 first responders and survivors, many of whom suffer from anxiety, PTSD, and other mental health conditions. Examples of LHI’s failures documented in NBC’s story include the following:

LHI is tasked with ensuring 9/11 survivors and first responders receive the medical treatment they need under the WTCHP. In the past few years, LHI has quickly deteriorated, leaving survivors and first responders fending for themselves. LHI has failed to authorize prescription drugs, has failed to pay medical bills, and has eliminated the case manager system that allowed claimants to work one-on-one with a case manager.

While LHI may have performed adequately in the beginning, the last few years have demonstrated a sharp decline in LHI’s commitment to helping 9/11 survivors and first responders. Although the NBC news story about LHI’s failures was released in September, the government had already begun soliciting new bids for a company to replace LHI in August of this year.

LHI has been around since 1999 and was previously awarded government contracts to assist in the administration of healthcare for service members and veterans. Since 2008, LHI has been administering WTCHP claims for individuals outside of metropolitan New York City.

Approximately 24,000 9/11 survivors and first responders living outside of metropolitan New York City have sought benefits through the WTCHP. For claimants who live within the metropolitan area, they can go to qualifying hospitals and healthcare providers within the city.
