A1. Outbreak

Measles is a highly contagious viral disease. Persons infected with measles can spread the disease to others from 4 days before up to 4 days after rash onset. Maculopapular rash appearing all over the body is a classic symptom of measles. Other symptoms include high fever, runny nose, sore throat and hacking cough. There is no specific cure for measles however, medications can be taken to alleviate symptoms caused by the virus. People generally recover from the virus within 2 weeks. In some rare instances severe problems can occur which include, pneumonia, encephalitis, seizures or meningitis.
In 2008 140 measles cases were reported in the United States. Travelers to Italy, Switzerland, Belgium, India, Israel, China, Germany, Pakistan, The Philippines and Russia accounted for 17 of the reported cases. 8 of the 17 travelers were visitors to the United States and the remaining 9 were residents. Illinois reported 32 cases, New York 27, Washington 19, Arizona 14, California 14, Wisconsin 7, Hawaii 5, Michigan 4, Arkansas 2, Washington DC 1, Georgia 1, Louisiana 1, Missouri 1, New Mexico 1, Pennsylvania 1 and Virginia 1. (Vincent Iannelli, 2014)

A2 and A3. Epidemiological Indicators and Data

64 measles cases were confirmed in the United States during January 1 to April 25, 2008. A majority of the cases were imported to the United States from other countries. Of the 64 reported cases 63 were unvaccinated against the measles virus. The epidemiology of this outbreak could be traced to its origin via chain of transmission. Ages of the patients infected with measles ranged from 5 months to 71 years old. 22% of the patients were hospitalized and no deaths resulted from the outbreak. 39% of the cases contracted the disease while in a health care facility. 84% of the cases were imported from other countries.

...Cataract Definition: Opacity of the lens that distorts the image projected on to the retina and which can progress to blindness. Types of cataracts include: * * Senile * Congenital * Traumatic * Secondary Anatomy and Physiology: * Cornea - It is the outermost lens of the eye, controlling and focusing incoming light. It shields the rest of the eye from dust, germs and other harmful foreign matter. * Sclera - The visible white part of the eye.The sclera is a protective layer that maintains the global shape of the eye and offers resistance to internal and external forces. * Iris - The part of the eye which is colored. The iris is a diaphragm that regulates the expansion and contraction of the pupil to allow in the required amount of light. * Choroid – contains blood vessels and supplies nutrients to the retina. * Ciliary Body - Connects the choroids with the iris and secretes aqueous humor that helps the eye its shape. * Retina - The retina is the link between the brain and the light entering the eye. The retina is a complex structure able to convert the impacting light into nerve impulses that are then sent to the brain along the optic nerve.  * Rods are photoreceptors responsible for peripheral vision and function at reduced levels of illumination. * Cones function at bright levels of illumination and are responsible for color vision and central vision. * Vitreous body – transmits light and gives shape to......

...a patient who develops a cataract? How does cataract formation represent a variance from normal anatomy & physiology? What happens in sensorineural hearing loss? How does sensorineural hearing loss represent a variance from normal anatomy & physiology? SENSES AND THE ENDOCRINE SYSTEM For years now researchers believed that cataracts are developed because the proteins in the eye change as people age. The changes in these proteins cause the lens to become cloudy. Smoking, poor nutrition, eye injury, exposure to excessive sunlight, and certain medical conditions such as diabetes, also may be factors that put people at higher risk of developing cataracts. Cataracts develop slowly. Some of the first signs people experience is a difficulty in reading the newspaper, or they experience blurry vision. Over a period of time the eyes become more sensitive to light, and seeing at night becomes especially difficult. A common symptom is that people with cataracts often say they feel they have a film over their eyes, as if they are looking through a piece of gauze. The condition actually may benefit some people who always had trouble seeing things that are near to them, such as the words in a book. The cloudiness of a cataract changes how light is focused and temporarily results in better vision for some people. They may find themselves able to read for the first time without eyeglasses, a condition sometimes called "second sight." As the cataracts worsen, however,......

...Crystallins Linked to Cataract Formation Abstract As biological resistance against cataracts, proteins called α-crystallins in the lens of the eye are present to keep denatured crystallins from precipitating and forming cataracts. Over time, these α-crystallins are increasingly bound to denatured proteins and contribute to the conglomeration of other crystallins themselves. Since the eye does not replace these essential proteins, the incidence of cataract formation increases without α-crystallin binding. Biochemists at the University of California-Irvine have recently observed trends in αB-crystallins’ interaction with structural γS-crystallin variations, which established a connection between cataract formation and the absence of the αB-crystallin. Molecular discoveries regarding αB-crystallin and γS-crystallin structures have also introduced the possibility of developing protein-specific drugs and corrective treatment for cataracts, as well as providing more widely available options for lower-income global populations. Introduction Cataracts are becoming increasingly prevalent in the aging world population. A study published in 2010 by the World Health Organization quoted the occurrence of visual impairment worldwide at 285 million; of these, 33% of avoidable visual impairment cases and 51% of avoidable blindness cases are caused solely by cataracts (Visual Impairment and Blindness 2010, S.P. Mariotti et al.). As defined by the American Optometric Association, cataracts......

... A cataract is a cloudiness of the lens in your eye that prevents light from being focused clearly on the retina, which can impair your vision.  There are three different types of cataracts. -Nuclear -Subcapsular -Cortical A nuclear cataract forms deep in the central zone (nucleus) of the lens. Nuclear cataracts usually are associated with aging. A subcapsular cataract occurs at the back of the lens. People with diabetes have a greater risk of developing a subcapsular cataract. A cortical cataract is characterized by white, wedge-like opacities that start in the periphery of the lens and work their way to the center in a spoke-like fashion. This type of cataract occurs in the lens cortex, which is the part of the lens that surrounds the central nucleus.  Cloudy or blurry vision.  Colors seem faded.  Poor night vision.  Double vision or multiple images in one eye.  Frequent prescription changes in your eyeglasses or contact lenses. Normal Vision Vision with cataracts  Macular Degeneration--loss of central vision due to damage to the macula and surrounding blood vessels.  Retinal Detachment--Medical Emergency.

...How is a cataract formed? The lens of an eye is made up of water and protein. The protein is arranged in a way that keeps the lens clear and allows light to pass through. A cataract forms when some of the protein clumps together and begins to cloud a portion of the lens. Over time it grows larger and affects your vision. [pic] Change from a normal lens epithelium (A) through proliferating epithelial cells (B, C) to final subcapsular fibrous plaque and formation of a new continuous basement membrane (lens capsule) (D). [pic] Risk Factors • Age • Close relatives who have/had cataracts (family history) • Diabetes • Ionizing radiation exposure • Statins • Long-term exposure to bright sunlight • Long-term use of corticosteroids - many people with asthma rely on inhaled, and sometimes oral steroids, as do people with chronic obstructive pulmonary disease. A study conducted by the Centre for Vision Research, University of Sydney, Australia, revealed that cataract risk is higher for patients taking these medications • Previous eye inflammation • Previous eye injury • Exposure to lead • Crystallins loss of function - A specific type of protein (crystallins) begins to lose function as the eye ages. As the protein loses function, small peptides, made of 10 to 15 amino acids, start forming and accelerate cataract formation in the eye, a study......

...concentration in the aqueous may result in cataract formation. Cataract A cataract is a lens opacity. Senile cataract is the most common type and is usually bilateral. Traumatic cataract, congenital cataract, and cataracts secondary to diabetes mellitus, galactosemia, other systemic diseases, and toxins are less common. Cataract Formation. Cataractous lenses exhibit protein alteration, lens edema, vacuole formation, necrosis, and disruption of the lens fibers. Cataract formation is characterized by a reduction in oxygen uptake and an initial increase in water content followed by dehydration. Sodium and calcium content is increased while potassium, ascorbic acid, protein, and glutathione content is decreased. Sugar Cataracts. Examples of sugar type cataracts are those produced by galactose, xylose and glucose. Galactose and xylose administered in large amounts to animals and blood glucose in excess, as in severe diabetes with persistent severe hyperglycemia, can produce cataract. Sugars in high concentration in the aqueous humor readily enter the lens and are converted to sugar alcohols by aldose reductase (galactose to dulcitol or galactitol, glucose to sorbitol, and xylose to xylitol). The sugar alcohols accumulate in the lens and have an osmotic effect causing water to enter the lens and causing lens cells and fibers to swell and become disrupted. These changes lead to formation of cataract (18). Corticosteroid Cataracts. Posterior subcapsular cataracts have been......

Cataract Surgery Experience at Vasan Eye Care

...Cataract Surgery Experience at Vasan Eye Care Blurred vision had become a way of life for Mrs. Chitra Mehra for the past few years. Having a medical history of high blood pressure and diabetes none of the doctors in her city ever agreed to operate on her. Recently she came to stay with her daughter and son-in-law. Seeing her suffer they decided to consult an eye specialist. They took her to the city’s leading eye specialist. The doctor informed them that she had cataract which was in advance stage and any delay in surgery may lead to permanent blindness. The doctor’s words came as a shock for all of them. They decided to go for a second opinion. Panic-struck they started looking for eye care centers in their city. Finally they decided to approach Vasan Eye Care. The hospital had a brand image and had recently opened its branch very near to their place of residence. As soon as they entered, the front desk staff welcomed them with a warm smile. Mrs. Chitra was registered by the staff and was escorted by another staff for consulting the doctor. Meanwhile her daughter talked to a few patients who were recently operated at the center. Most of them were happy and satisfied with the services of the hospital. The doctors and other medical staff were very caring as portrayed in their advertisement.

...they are genetic or acquired. Many times diseases are age related and others are genetic that someone is born with. Some diseases of the special senses are Age related macular disease, glaucoma, cataracts, detaches retina, deafness, Meniere’s disease, and Ataxia. Each caused from something different and each effecting everyday life of an individual. Age related Macular disease is also referred to as Macular degeneration. It is the leading cause of vision loss in people over 50. It is caused from damage done the macular which is the smallest part on the retina. Once damage is done to the macula, the individual’s eyesight may become dark, discolored, blurry, or distorted. This causes overall eyesight loss and damage to everyday eyesight. Glaucoma, is increased pressure inside the eyes. Intraocular pressure is the increased pressure overtime, the increased pressure causes damage to the optic nerve in which images are transmitting through the optic nerve to the brain. Damage from glaucoma causes blindness. This typically occurs in individuals over the age of 40 whose aqueous humor is not flowing properly. Cataracts is the clouding of the eye lenses typically causing blurred or discolored vision. Individuals who develop cataracts usually have one or more previous eyesight issues. Cataracts is treated with a surgery that removes the clouded lenses and replaces it with a clear one. Detached Retina, is when the retina is detached from its connective tissue, thusly being......

Business Case

...spend over 20% by the year 2050 (Drouin et al., 2008.) In the developing world on the other hand demand exceed capacity; it was estimated that in 1997 over 12 million people were blind in India from cataracts, while a further 3.8 million new cases are developed each year, and current capacity for surgery is far below this level (Thulasiraj et al., 1997.) Better health care operations are clearly required to deal with issues of ageing population, increased costs and unmet demand. One case that provides clues to such means is Aravind, the largest eye care provider in the world, with over 2.5 million operations performed and 20 million patients treated in the last thirty years. An Indian non-for-profit organization in which two thirds of the patients are treated for free, Aravind attends its goals by strict attention to cost optimization. THE STORY OF DR. V Dr. Govindappa Venkataswamy (known as Dr. V) retired at age 58 from a life in public health as an ophthalmologist in India. He then started, with his sister and brother in law, an 11 room clinic in southern India to treat poor patients who suffered cataracts and other eye diseases. Thirty years after these modest commencements Aravind comprises a network of five regional hospitals that perform over 200,000 cataract operations per year, 70% of them without cost to the patient (Chang, 2007). Aravind is not funded through government grants, aid-agency donations or bank loans. Instead, the model Dr. V chose......

... 4. cataracts: A cataract is a clouding of the lens in the eye that affects vision. Most cataracts are related to aging. Cataracts are very common in older people around the age of 80. Although most cataracts are related to aging, there are other types of cataract. * Secondary cataract: Cataracts can form after surgery for other eye problems, such as glaucoma. * Traumatic cataract: Cataracts can develop after an eye injury, sometimes years later. * Congenital cataract: Some babies are born with cataracts or develop them in childhood, often in both eyes. * Radiation cataract: Cataracts can develop after exposure to some types of radiation. Cause of Cataracts: The lens lies behind the iris and the pupil. It works much like a camera lens. It focuses light onto the retina at the back of the eye, where an image is recorded. The lens also adjusts the eye’s focus, letting us see things clearly both up close and far away. The lens is made of mostly water and protein. The protein is arranged in a precise way that keeps the lens clear and let’s light pass through it. But as we age, some of the protein may clump together and start to cloud a small area of the lens. This is a cataract. Over time, the cataract may grow larger and cloud more of the lens, making it harder to see. You don’t have to be a senior citizen to get this type of cataract. In fact, people can have an age-related cataract in their 40s and 50s. But during middle age, most cataracts are......

Arvind Eye

...ARAVIND EYE HOSPITAL EXECUTIVE SUMMARY Aravind Eye Hospital was set up in 1976 by Dr. Govindappa Venkataswamy (or Dr. V) with the noble intention of being a private, non-profit hospital that provided quality eye care. The case is set against the backdrop of the social problem of blindness in India. With over 12 million blind people, 70 – 80% of the cases are primarily due to cataract that can be treated through surgery. However, the low per-capita income as well as the prevalence of cataract cases among the poorer sections of the society made the surgeries entirely unaffordable. Aravind Eye Hospital started off as a 20-bed facility in 1976 in Madurai, soon started a 250-bed main hospital and over time, expanded to Theni, Thirunelveli and Coimbatore. The central feature of the service provided is the clear delineation of services in the form of paid service in the Main hospital and non-paid service in the Free hospital. They also held several Eye camps to mobilize the poor in villages and spread awareness of the dangers of their ailments. The vision that motivates Dr. V is to market cataract surgery such that it reaches every nook and corner of the developing countries facing this problem. Clearly, profit or a healthy bottomline is not the motivator in this case. However, Aravind faces some real issues at the field level that need urgent resolution to help it achieve its mission of bringing eyesight to the masses of poor people in India.

Analysis of Ophthalmological Industry

...Ophthalmology devices are used for a range of key procedures, including vitreo-retinal surgery to treat retinal conditions and refractive surgery to restore impaired vision in cases such as hyperopia and myopia. Devices are also used for ophthalmological surgery in the treatment of glaucoma, the leading cause of blindness, and cataracts, and the number one cause of treatable blindness, to replace the natural eye lens with an intraocular lens. Eye Health across the Globe According to the World Health Organization, there are more than 180 million individuals in the world who are blind or are at serious risk of becoming blind. This number is staggering when you consider that as many as 75 percent of these cases could have been prevented or treated at an early stage.  Unfortunately, proper eye care is either unaffordable or unavailable in many areas of the world today. This problem is compounded by the fact that many within the medical communities that serve these areas lack the proper education, tools and resources to provide adequate care. The world's population is aging, and the prevalence of blindness caused by treatable or preventable eye diseases – such as cataracts and glaucoma – could continue to grow at an exponential rate without proper action. Global Scenario Changing trends in diet and lifestyle as well as increased longevity are growing the market for ophthalmological treatments: the global ophthalmic device market is expected to reach $28 billion by 2016......

Visual Perception Deficit: Cataract and Glaucoma – graduate studies | Visual Perception Deficits | Cataract & Glaucoma | Submitted by: | Nadine Angelica C. Gadia – Casiño, RN | March 18, 2012Submitted to:Ms. Delia V. Realista, RN, MANProfessor | | I. Intoduction Cataract Cataracts are common and significant cause of visual defects all over the world. A cataract is an opacification or clouding of the lens of the eye. Cataracts develop because of the alteration of transport of nutrients and metabolism in the lens. This interferes with light transmission to the retina therefore affecting the ability to perceive images clearly. All cells of the lens formed in the lifetime is retained therefore prevalence of cataracts increase rapidly with aging. WHO estimates that cataracts account for 48% of reversible blindness worldwide, which translates to about 18 million people. Cataracts affect slightly more women than men. The Beaver Dam Eye Study in the US found that 23.5% of women and 14.3% of men had a visually significant cataract by the age of 65 years. Although cataracts can be surgically removed, in many countries surgical services are inadequate, and cataract remains the leading cause of blindness. Age is the greatest risk factor in the occurrence of cataracts. Cataract, though with unclear links, may be acquired through heredity and genetics (e.g., Wilson's disease, galactosaemia, myotonic dystrophy). Early formation of cataracts is associated with the following risk factors: *......
