Leprosy
Leprosy (Hansen's Disease), sometimes called "Hanseniasis" or "H.D.," is a chronic my cobacterial disease of man, caused by Mycobacterium leprae (infectious in some cases), primarily affecting the peripheral nerves and secondarily involving skin and certain other tissues/organs, in particular the eye, mucosa of the nasal and upper respiratory tract and also the testes. In most cultures, HD still carries a strong stigma that sometimes makes more trouble for the patient that the actual leprosy itself.
One of the main characteristics of Leprosy is its ability to affect the various nervous systems of the body, particularly the peripheral nerves. The key targets of M.leprae (Mycobacterium leprae) are the nerves' Schwann Cells. Leprosy does not affect the Central Nervous System. Where the sensory nerves are damaged, in varying degrees, they cannot register pain. Where those nerves supply the extremities of hands and feet, the latter are vulnerable to burns and other injuries that can often result in the loss of fingers and toes and sometimes hands and feet. Where the eye is affected, corneal anesthesia. Cranial Nerve involvement, can often lead to blindness, where the lack of health education makes the sufferer unaware of the means to prevent injury due to dust or other irritants. Where the motor nerves are involved, various forms of paralysis such as "Dropped Foot", "Dropped Wrist", "Clawed Hand", "Lagophthalmos" (eye cannot close due to nerve paralysis) can result. Where the autonomic nerves are damaged, the hair follicle, particularly in the cooler areas such as the eye-brows, can often result in the loss of hair in the affected parts. Damage to the autonomic nerves also can result in poor or no function of the sweat and sebaceous glands. This causes a drying of the skin and consequent cracking, exposing the sufferer to secondary infection.
Leprosy is not a curse from the gods or divine punishment for some sins committed in the past. Leprosy is a disease like any other disease and it is TOTALLY CURABLE. Another myth that still prevails, even in "educated" societies, is that the disease causes flesh to rot and fingers and toes to "drop off". Nothing could be further from the truth. Tragically, limbs that are damaged, because the victim cannot feel pain, sometimes have to be amputated but, we can now detect the disease before the patient is conscio...

... dissolves the germ by certain chemicals or enzymes. The second type of protective mechanism is specific and the body's defense system can only "recognize" a foreign invader if it has experience in this identification of certain antigens. In Lepromatous patients, their macrophages can ingest the M.leprae but cannot digest (kill) because there are no "T-Type" ("T" for Thymus, the gland that programs these cells) lymphocytes to assist the macrophages to produce the needful digestive juices or enzymes. So, in the case of Lepromatous leprosy, the very cells that are meant to kill off the bacilli, are actually transporting them around the body and providing an environment in which they may even be able to multiply.
At the present time though, leprosy cannot be prevented. Research on a preventive vaccine, however, is slowly progressing. This vaccine will be used the same way we use vaccines of Smallpox, Typhoid, Cholera, Plaque, and etc. A vaccine of killed or weakened leprosy bacilli will be used to immunize everyone from the disease. Already, a vaccine of killed leprosy bacilli has been used to immunize mice and armadillos against leprosy. Millions people will need to receive MDT.
The B cells, T cells, Macrophage, and Antibodies are all a very large part of the immune system. There are two types of T cells, killer and helper T cells. Killer T cells find and destroy cells infected with bacteria, and helper T cells control the activity of other cells in the immune system. Then, B cells are considered the “clean up crew,” attacking any bacteria or viruses the T cell left behind. They also make antibodies, which are essential for trapping invading viruses and
Flaccid dysarthria results from damage to the lower motor neurons (LMN) or the peripheral nervous system (Hageman, 1997). The characteristics of flaccid dysarthria generally reflect damage to cranial nerves with motor speech functions (e.g., cranial nerves IX, X, XI and XII) (Seikel, King & Drumright, 2010). Lower motor neurons connect the central nervous system to the muscle fibers; from the brainstem to the cranial nerves with motor function, or from the anterior horns of grey matter to the spinal nerves (Murdoch, 1998). If there are lesions to spinal nerves and the cranial nerves with motor speech functions, it is indicative of a lower motor neuron lesion and flaccid dysarthria. Damage to lower motor neurons that supply the speech muscles is also known as bulbar palsy (Pena-Brooks & Hedge, 2007). Potential etiologies of flaccid dysarthria include spinal cord injury, cerebrovascular accidents, tumors or traumatic brain injury (Pena-Brooks & Hedge, 2007). Possible congenital etiologies of flaccid dysarthria include Moebius syndrome and cerebral palsy. Flaccid dysarthria can also arise from infections such as polio, herpes zoster, and secondary infections to AIDS (Pena-Brooks & Hedge, 2007). Additionally, demyelinating diseases such as Guilian-Barre syndrome and myotonic muscular dystrophy can also lead to flaccid dysarthria (Pena-Brookes & Hedge, 2007). The lower motor neuron lesion results in loss of voluntary muscle control, and an inability to maintain muscle tone. Fasciculations, or twitching movements, may occur if the cell body is involved in the lesion (Seikel et. al., 2010). The primary speech characteristics of flaccid dysarthria include imprecise consonant production, hypernasal resonance, breathiness, and harsh voice (...
There is no vaccine for HIV, but there are some drugs that can extend their lives. Some of the treatments that are offered are very expensive and are not available to all people with HIV. Also, these treatments do not work for about 20% of people who have tried them. Some of the best ways to avoid contracting HIV is to abstain from sexual intercourse and from sharing needles if you do drugs. Do not share personal items that may be contaminated with blood.
Although accountability has always been an issue, the injustices that are currently occurring make it priority. Police officers are getting “special treatment” and are not facing charges for crimes they have committed. Police officers are not held accountable for their a...
Throughout the ages, while the origins to this day continue to be debated, the strength and potency of the disease have rarely been in question. Syphilis, while not viewed as a huge threat due to a decreased number of cases in the mid-late 1990s, needs to be taken more seriously by the public because it is more dangerous than many realize, especially because it is extremely contagious, it is extremely elegant in the symptoms it produces, it has played a larger part in history than many would think, and there is a certain stigma which surrounds the disease, which in turn pushes individuals away from receiving the necessary testing.

Hansen’s Disease also known as Leprosy dates back to at least 4000b.c. Evidence of the disease’s presents in ancient times was found on an Egyptian papyrus dating from around 1500bc. These earlier cultures believed it was a curse or punishment from the gods. During the middle ages, the afflicted wore special clothing and rang bells to alert the uninfected of their presence. The first known origin of this disease is Egypt from here Roman Crusaders contracted the disease and brought it back to Europe and from Europe to America.
Edgar Allan Poe, born January 19, 1809, was an American poet, widely known for his literature and his belonging toward Romanticism. Born in Boston, he was soon orphaned after the abandonment of his father and death of mother between 1810-1811. In 1827, Poe released his first book, “Tamerlane and Other Poems”. This was not the only one, however, for he released several other books before the death of his older brother in 1831. After his brother’s death, Poe made the decision to become a writer.
Although most people don't realize it, one of the most weakening diseases of the world can often be found crawling around in the shrubs and tall grasses of a person’s backyard .It does not mean that only dirty yards have this disease but it is found in every Americans backyard. The disease is called Lyme disease. Now I will be elaborating on the disease.
Many turn to social or media throughout their day to gain insight on activities and event that is going on in the world. The media does not have to report the truth so individuals may gain untruthful information and a cloudy perception. Individuals tend to turn to the media to gain an opinion about someone or something.
The most common type is Peripheral Neuropathy. It is also referred to as distal symmetric neuropathy or sensorimotor neuropathy. In this type, the legs, feet, toes, arms, and hands experience pain and loss of sensation. Typically, the lower extremities are involved before the upper extremities and a loss of reflexes is common. It is with this type of neuropathy that ulcers, wounds, infections, and in severe cases, amputations are most common (Dyck, Feldmen, & Vinick).
Unlike occupational deviance, abuse of authority in regards to police, is the act in which officers use the powers given to them in malice (Barker, 1991). In more serious cases the abuse of power can result in death, as was the case in the recent Michael Brown shooting. Officer Darren Wilson took aim at 18 year old Michael Brown, witnesses recording, and opened fire resulting in the 18 year olds death. This is just one of the many examples of corruption still existing within the police agencies which are designed to protect us.
The police handle an essential part in society as its protectors. The law enforcement officers look out for the citizens and try to protect their safety and happiness whenever possible. Throughout the years, however; the society has questioned the use of force, racism and internal corruption as well as other forms of misconduct by officers of the law. Some people claim that many of these problems are misconstrued by the media and blown out of capacity; these officers are simply doing their job. Others argue that these circumstances can be drawn back to poor training and policies. Others maintain that the whole system needs to be changed and that with the rise in crime; officers have become enforcers more than protectors.
Karl Marx was a German philosopher, economist, and sociologist, as well as a political revolutionary. In 1843 he began constructing the “Communist Manifesto” alongside his companion Friedrich Engels. The Manifesto began by arguing class struggles and elaborating on the exploitation of one class from another throughout history. “The history of all hitherto existing society is the history of class struggles.” (__) Marx explains that throughout history we see the oppressor and the oppressed in constant opposition to one another—sometimes openly and others concealed. Each time the fight ends between the two either a revolutionary reconstruction is implicated or in the classes demise. The Manifesto continues to show that the modern bourgeoisie is the product of several of th...
Many things come to mind when the word police is said aloud. When asked, one person provided the words “protection, and law”, while another simply stated “pigs”. We’ve all formed opinions on the police whether it be positive or negative based off of what we see in the news, hear from others, and from our own personal experience. The politically correct definition of police is “the civil force of a national or local government, responsible for the prevention and detection of crime and the maintenance of public order”. In the United States of America, the police have made a lasting impact on the public’s view of them most of which is unpleasant. What we forget however, is that the police are formed of individuals who set out to keep us safe and do good. Police officers do not wake up in the morning with the urge to kill a civilian and abuse the power they hold. They get up in morning ready to go to work and carry out their jobs like every other person does.
