Langerhans Cell Histiocytosis

Langerhans Cell Histiocytosis Langerhans cell histiocytosis (LCH or histiocytosis X) is the most common form of dendritic cell type of histiocytic disorders. LCH can be divided into three groups on the basis of the number of lesions and systems involved: the unifocal (localized) form, presents between 5 and 15 years of age, in approxi ­mately 70% of LCH cases, limited to a single bone or a few bones, and may involve the lung. Multiple bones as well as the reticuloendothelial system (i.e., the liver, spleen, lymph nodes, and skin) involvement and diabetes insipidus are seen in multifocal unisystem (chronic re ­curring) form which constitutes approximately 20% of cases. Typi ­cally seen between 1 to 5 years of age. The fatal form is the multifocal multisystem (fulminant) form comprising ap ­proximately 10% of LCH cases. Seen in the first 2 years of life and it disseminately involves the reticuloendothelial system, anemia, and thrombocytopenia. Eosinophilic granuloma, Hand-Schà ¼ller-Christian disease, and Letterer-Siwe disease are older names used when these were thought to be different diseases; these names should now be discouraged. Langerhans cell histiocytosis is characterised by uncontrolled monoclonal proliferation of abnormal Langerhans cells, which can infiltrate ubiquitously all the tissues or organs as well as lymph nodes. The histiocytic infiltration is followed by chronic inflammation and the formation of granulomas. Uncontrolled immune response activation is the most likely etiology by an as yet unknown antigen. Bone lesions are seen in approxi ­mately 80% of LCH patients. LCH has a predilection to involve the flat bones with skull being the most common flat bone involved, followed by the mandible, ribs, pelvis, and spine. Skull lesions can be either asymptom ­atic or manifest with focal pain and soft-tissue swelling in the scalp. â€Å"Punched-out† lytic lesions are seen in skull lesions seen on radiographs with asymmetric destruc ­tion of the inner and outer cortices, which results in a characteristic bevelled edge. Mastoid bone is the classical location when temporal bone is affected. Calvarial disease lacks periosteal reaction unlike other bone lesions. The term geographic skull is used when skull lesions grow in size and coalesce, creating a map like appearance. Vertebra plana (symmetric flattening of vertebral body) is seen with involvement of spine. Diaphyseal or metaphyseal involvement seen in long bones. â€Å"Floating teeth† is seen if there is enough alveolar d estruction. Other findings include hepatomegaly with solid or cystic lesions in liver. Lymphadenopathy with cervical predominance. MRI brain will reveal absence of posterior pituitary bright spot, and thickening of pituitary stalk if there is CNS involvement. Lung involvement shows centrilobular nodules or cysts of varying sizes, with mid- to upper-lung distribution and spar ­ing of costophrenic angles. Meyer et al conducted a study in 1995 in Philadelphia on 42 patients. 83% of the patients had at least one affected bone. All children with lesions of the skull base (Fig 1 ) and seven of eight with facial lesions (Fig 2) had bone destruction with associated soft-tissue masses. Calvaria 13 Intracranial soft tissue 4 Skull base/face 15 According to D’Ambrosio et al 2008, who did study on 100 patients in New York Ninety-six percent of the patients in this series had bone involvement. Fifty-eight of 96 patients (60%) had a solitary bone abnormality, and 38 patients (40%) had multiple lesions. By far, the most common bone involved in the series was the skull, affecting 52 of 96 patients (54%). In particular, the calvarium was affected in 45% of patients. Of the patients with calvarial involvement, the parietal bone was most commonly affected. The maxilla and/or maxillary sinus was affected in 8% of patients in the series. In the study done by Khatami et al 2010 in Iran on 48 patients, 38 of them (79.2%) had bone involvements; skull was involved the most (66.7%), followed by Pelvis (31.3%), Femur (31.3%), Sphenoid (30.0%) and ribs (16.7%), temporal bone in 4.2% Radiation Issue of CT Concerns about carcinogenicity of computed tomography radiation began in the early 2000s. In recent times many examination protocols and software and hardware modifications have been made to reduce CT radiation dose. The definite risk of radiation exposure is not quantified. So, it is better to follow the principle of As Low As Reasonably Achievable (ALARA). This can be achieved by ensuring that the examination is clinically indicated and by keeping the radiation dose to the minimum with the help of technical advances as described below126. Tube current modulation is a very useful tool to control patient exposure with CT examinations. In this technique the scanner will produce less number of x-ray photons in regions of lower attenuation and higher values of tube current in regions of increased attenuation. This is of two types: Angular modulation and z-axis modulation. In angular modulation differences in attenuation in x-y plane is measured with the help of two localisers (lateral and anteroposterior views) and the tube current is modulated accordingly during rotation. In z-axis modulation the attenuation differences along the length of the patient are calculated with a single anteroposterior localiser and the tube current is modulated. The z-axis organ based tube current modulation is as much or more effective than thyroid and eye shields at reducing radiation, without the regional image noise caused by shields. Newer reconstruction technique called iterative reconstruction significantly reduces the patient dose. In this the initial projected image is iteratively compared with the model image of the vendor. Then the algorithm intelligently decreases the noise in the image. There by a noise less image can be obtained even with a low dose CT. But this technique is more time consuming than the conventional filtered back projection technique. With the newer development of hybrid iterative reconstruction which uses both the above techniques, the speed has been considerably increased. Accurate patient centering can also decrease the patient radiation. Other techniques such as optimization of tube potential, beam-shaping filters also make a significant contribution to dose reduction. Newer developments which hold promise to reduce the radiation dose in the future are compressed sensing, volume of interest and interior tomography techniques, and photon-counting detectors127-136. Low dose MDCT of PNS can be done by reducing the mAs. This is the most effective way of reducing patient exposure. The effective dose delivered by a standard dose MDCT protocol is 0.70 mSv in men and 0.76 mSv in women, whereas the effective dose delivered by a low dose MDCT protocol is 0.047 mSv in men and 0.051 mSv in women which is equivalent to standard four view radiography of PNS. Low dose CT can be used for the follow up of patients with chronic sinusitis and in tumors where the presence of soft tissue mass or bone destruction is used for follow up18.

Why I Deserve a Scholarship

I believe that I deserve a Big33 Scholarship for several reasons. My high attendance, academic achievement, determination, time management, financial need, motivation for college and to achieve better are all reasons I will discuss of why I believe I deserve a scholarship. The first reason is because I am very diligent in my studies and attend my classes every day. In my entire schooling career I missed very minimal amounts of school. I have obtained perfect attendance in grades 9th, 11th, and am working on 12th grade. In my 10th grade year I only missed one day of school. I have also had high honor roll every year in high school and plan to continue it throughout college. Another reason is I am very determined when it comes to both work and school. I take both of these aspects very seriously and when I’m given an assignment or task, I feel very obligated to not only complete it, but do so both correctly and in a timely manner. Also I am very good at managing many things at one time. For example, in my sophomore and junior year in high school I managed school, homework, church volunteer work, practicing the piano and attending my lessons and performances, babysitting (about 40 hours per week on the weekends, overnight) family and church activities and spending time with my friends, family and boyfriend. In my senior year I am managing school, homework, work, college and scholarship applications, practicing the piano and attending my lessons and performances, babysitting my nephew about one night per week, family activities, church events, student government events, and spending as much time as I can find with my friends, family, and boyfriend. Also, with just working a minimum wage job, I do not have enough money to go to college on my own funds. I am putting away a little bit of money from each pay check since I started my job but this, though it does add up and will help greatly is not going to be enough to cover my total of six years of schooling that is required to reach the position that I desire. My main motivation for going to college is to get ahead of the society. I want to make something of myself instead of being like so many Americans today and not having enough education to stay employed in the jobs that are bombing and have a high potential for growth. Nursing greatly interested me because I enjoy working with people and like to make their day better in any way I can. I absolutely love infants and that is why I want to continue my education until I reach a level of a Neonatal nurse. I want to obtain a job that I love to go to everyday. The quote by Confucius â€Å"Choose a job you love and you’ll never have to work a day in your life† is a huge motivation to me. That is why I chose nursing as my major, so I would get to work with infants, my favorite thing to do. These are a few reasons of why I believe that I deserve a scholarship from Big33 so that I can continue my education from high school and attend college.

Grossberg And Hartog Reaction Paper - 1071 Words

Grossberg and Hartog Reaction Paper Asha McWilliams In A Judgement for Solomon: The d’Hauteville Case and Legal Experience in Antebellum America, Grossberg outlines the complex legal experiences of the d’Hauteville family and the effect their experiences have on Antebellum America. On August 22, 1837, Ellen Sears and Paul Daniel Gonzalve Grand d’Hauteville were married and moved to Switzerland. In the winter of 1838, Ellen became pregnant and pleaded with Gonzalve to let her return to America to give birth to her child. After much pleading, Gonzalve gave in and let Ellen leave; however, after giving birth, Ellen refused to return to Switzerland, citing cruel treatment from Gonzalve as her reason for staying away. Eventually Ellen†¦show more content†¦Furthermore, they gave legitimacy to Ellen’s claims of mental cruelty. Yet, the court couldn’t give Ellen â€Å"unrestrained maternal power,† so the ruling pertained only to the â€Å"present custody of the child.† This meant that Gonzalve could bring the case again, whenever he so chose. The public reaction was largely divided, with regional and social divisions becoming apparent. The press verdict was far from unanimous, with newspapers in various regions espousing far different ideas. While a Philadelphia paper praised the idea of the discretionary power of judges in protecting the welfare of children, papers in New York and Boston continued to promote the idea of paternal power. Thus, an apparent shift in public opinion was underway. The emergence of divisive new ideas indicated the progressive movement towards greater maternal rights. This drastic change in public opinion can be best understood by analyzing the case of Abigail and Asa Bailey. In 1792, Abigail Bailey was quickly granted a divorce from Asa Bailey. However, Abigail waited twenty-two years to file this petition for divorce, as Asa, first had an affair just three years after their marriage in 1770. It is interesting to compare Abigailâ€℠¢s case to Ellen’s because in both cases, each woman repeatedly cites her hesitation to take legal action because of what she believes to be her duty to her husband. However, what is considered cruel enough to justify breaking

HORROR FILMS In this paper, I will be discussing reviews on horror films and gothic horrors using the movie mama as my main example. My aim is to analyse the horror genre and the emotional effects it has on different people. My objectives are to identify and analyse the generic elements of the horror genre, gather people’s opinions about the horror genre and to find out the reasons for these opinions. To aid my research, I have prepared and shared out questionnaires with open and closed ended questions to gather people’s opinions. I have also held focus groups. During the twentieth century, definitions of gothic books and films have broadened and changed significantly almost beyond original recognition. However, one of the reasons for the gothics continued popularity is its ability to change and recreate itself. There are some key elements that characterise twentieth-century gothic, one of them would be that in the early part of the century, the manner in which the real-life horror of two world wars takes over from the imagined horrors of the super natural and superstitious. Tortured individuals who in the nineteenth century refused to play dead began to do so on a massive scale during and after the First World War Armitt (2011) The horror genre really has no clearly defined boundaries and so displays characteristics associated with science fiction, fantasy, adventure and sometimes even thriller.

Essay about Gun Control Problems and Solutions - 968 Words

The problem with guns is fairly obvious: they decrease the difficulty of killing or injuring a person. In Jeffrey A. Roths Firearms and Violence (NIJ Research in Brief, February 1994), he points out the obvious dangers. About 60 percent of all murder victims in the United States in 1989 (about 12,000 people) were killed with firearms. Firearm attacks injured another 70,000 victims, some of whom were left permanently disabled. In 1985, the cost of shootings was an estimated $14 billion nationwide for medical care, long-term disability, and premature death. In robberies and assaults, victims are far more likely to die when the perpetrator is armed with a gun than when he or she has another weapon or is unarmed. I believe that†¦show more content†¦This has been the position of the NRA for quite some time, and it is certainly one with which I agree; Felons and ex-cons should not have access to weapons, and many misdemeanors and juvenile crimes should also count against a persons adult record. Stiffer sentences for gun crimes would be effective in using fear of reprimand as a crime deterrent. National as well as community funded gun education courses would increase gun awareness and safety. These programs could even be extended to public schools. Many guns are involved in accidents that could easily have been prevented by a little care or forethought. Also gun purchasers could be required to take lessons in gun safety, at the purchasers expense. Again, the NRA has long been a proponent of gun education. Gun control is severely weakened by the few loopholes that exist in the system. These loopholes make it possible for minors and felons to obtain outlawed and high-powered weapons. They also serve to weaken the strength of the Brady- Bill and Gun registration. Adults are prohibited from transferring firearms to juveniles, but are not required to store guns in securely locked cabinets. This allows kids to get access to them.

Collecting Cartoon Models Free Essays

Collecting cartoon models One of my favorite hobby I enjoy is collecting cartoon models. Collecting cartoon models is an important thing in my life. I like plastic model and come in pieces, I have to put them together. We will write a custom essay sample on Collecting Cartoon Models or any similar topic only for you Order Now Plastic model is easier to save, this is why I don’t like glass models. I know model is in my primary school. If I like a cartoon I will collect a model of it. I have spent a long time collecting models. I started to collect models when I was 12 years-old. Near my primary school there is a model shop, where you can see many types of models. The owner has more than 3000 models in the shop because he likes models too. He is my friend now. My first model was bought in this shop. I bought a small size, it’s not expensive, but that is my favorite one. Every models I will spend a lot of times to search it, which standing is my favorite, which size is the best one. If I want buy a model, maybe I will prepare a long time. For example, I love Doraemon, he look like a blue cat, but no ears, because a mouse ate his ears, he is a robot. He has a younger sister, and he has many friends, the best one name’s Da Xiong, is Doraemon’s owner, he is very timid boy, but Doraemon always help him. I have more than hundred models about this cartoon, I have Da Xiong, Jing Xiang, Pang Hu, Xiao Fu, and Doraemon’s younger sister Dorami. My mother knows this hobby when I am 14 years-old, because I told her I want bought a display case, so I have a very big display case, it’s a glass one. The case has 7 shelves, it is tall than me, I think it can put 6 person like me in my display case, it is very big. I put my models in the display case, it must be very carefully. Because if you not carefully the models maybe will break or change their standing. Collecting models is fun thing to do, it is interesting for me. I like to assembly them by myself. It makes me happy and calm, the reason is because I need pay attention when I do it. When you assembling models and at the same time you try to do another thing, your models maybe can’t do like you want, you will have error, and make your models break. I have more than a thousand models, the biggest one is tall 115cm, like a person; the middle size needs more time to assembly them, because the middle size is easier than other ize to assembly it, they are the most complex; and the smallest size, you can put them on desk or car dashboard. I can change models color or standing, some models you can paint them by yourself, when you buy the models, in the packing box maybe they give you tools to paint. I like paint my models, but I am not a good painter. Collecting cartoon models is a fun hobby for me, I really enjoy it, it’s not easy for a beginner. If you just a beginner, mayb e you don’t know how to deal some part, which part put together and use which color. That is a big problem. But when you start to assembly models, I am sure you will love it, because you accomplish a model by yourself, it can give you a chance to help you build your confidence, maybe you will say, â€Å"Look! I am the winner, I can complete it by myself! † If you want buy a model you like, you need search for them in many model stores, because at that time, model isn’t very popular in China, you need ask other and find the model stores, maybe the shop is in some small road, you may spend a lot of time searching for models and the way, if you want to have as many models as me. But it’s still fun for me after all these years. [pic] How to cite Collecting Cartoon Models, Essay examples

Why is Leonardo da Vinci considered a Renaissance man Example For Students

Why is Leonardo da Vinci considered a Renaissance man? A man who has broad intellectual interests and is accomplished in areas of both the arts and the sciences. That is the definition of a Renaissance man. Leonardo ability to observe and study, then demonstrate those things in his art, makes him a perfect example of a renaissance man. Leonardo Da Vinci was one of the greatest inventors. He was also one of the most famous scientists of recorded history. His genius was limited by time and technology, and was driven by his curiosity, and his instinctive sense of the laws of nature. Dad Vinci was dedicated to discovery of truth and the mysteries of nature, and his contributions to science and technology were legendary. As the classic Renaissance man, Leonardo helped set a curious and superstitious world on the means of reason, science, learning, and tolerance. In his time, he was an internationally famous inventor, scientist, engineer, architect, painter, sculptor, musician, mathematician, anatomist, astronomer, geologist, biologist, and philosopher. In an era when left-handedness was considered the devils work and lefties were often forced to use their right hand, Leonardo actually used his left hand. People say that this difference was an element of his genius, since his mind allowed him to see beyond the ordinary. He even wrote backwards, and his writings are easily deciphered only with a mirror. Between 1490 and 1495 he developed his habit of recording his studies in illustrated notebooks. His work covered four main themes: painting, architecture, the elements of mechanics, and human anatomy. All one hundred twenty of his notebooks were written backwards. Today, Bill Gates is known o have bought one of his notebooks for thirty million dollars. Born in 1452, as an illegitimate son of Seer Piper Dad Vinci, Leonardo was sent to Florence in his teens to apprentice as a painter under Andrea del Veronica. He quickly developed his own artistic style which was unique and contrary to tradition. He even went so far as to make his own special formula of paint. Leonardo went beyond his teachings by making a scientific study of light and shadow in nature. The thought that objects were not comprised of outlines, but were actually three- dimensional bodies defined by light and shadow. Known as chiaroscuro, this technique gave his paintings the soft, lifelike quality that made older paintings look cartoons and flat. He also saw that an objects detail and color changed as it went father and closer in the distance. This technique was called suffuse. His study of nature and anatomy emerged in his realistic paintings, and his dissections of the human body made him famous for remarkably accurate figures. He was the first artist to study the physical proportions of men, women and children and to use these studies to determine the ideal human figure. Leonardo was also a bought caged animals at the market Just to set them free. Later Dad Vinci became the court artist for the duke of Milan. Throughout his life he also served various other roles, including civil engineer and architect (designing mechanical structures such as bridges and aqueducts), and military planner and weapons designer (designing tanks, catapults, machine guns, and naval weapons) Leonardo hated war, he called it beastly madness ,but since Renaissance Italy was constantly at war he couldnt avoid it. He designed numerous weapons, including sessile, multi-barreled machine guns, grenades, mortars, and even a modern-style tank. He drew the line, however, with his plans for an underwater breathing device, which he refused to reveal, saying that men would likely use it for evil in war. Leonardo dad Vinci had many innovative designs, scientific accomplishments, and artistic masterpieces. High Renaissance and Mannerism in Northern Europe and SpainSome of his innovative designs include: flying machines, parachutes, submarines, underwater breathing devices, self floatation/ocean rescue devices, swimming fins, pumping mechanisms, water turbines, dredging systems, team calorimeters, water-well drill, swing bridges, canals, leveling/surveying instruments, cranes, pulley systems, street-lighting systems, convection roasting spit, mechanical saw, treadle-operated lathe, compasses, contact lenses, and military weapons. Some of his famous scientific accomplishments include: proposing the earth rotates around the sun, proposing that the moons light is reflected sunlight, correctly explaining why sea shells are sometimes found miles inland on mountain tops, and creating the first textbook of human anatomy.
