facilities were initially “limited greatly by the lack of special wards or buildings where such cases could be isolated”. (Godias and Lowell 1952) The lack of proper facilities were only exacerbated by the conditions that people lived within the city.
Tuberculosis was commonly associated with dirty, poorly lit conditions, and a significant group of the population lived in tenements characterized by dark ill ventilated areas. Daniel Freund, provides an example of these conditions using a Jacob Riis picture entitled “Baby in slum tenement, dark stairs –its playground”.(Freund 2012) The title of the picture is self-explanatory, and the idea is clear, that the darkness and dirty conditions bred disease and contributed the spread of tuberculosis. These conditions were addressed by modifications to the building code outlined by the Tenement Act of 1901.
Daniel Freund notes that the act resulted in the terraced structure of buildings that allowed a greater infiltration of light into the city below. The impact was used to redesign new residential buildings in a manner that drastically increase exposure to sunshine. (Freund 2012) The design is still apparent today in the designs of the Chrysler building as well as the Empire state building and the push for light became central to the reduction of disease in the city.
Heliotherapy became important during this time because it was used in the treatment of Tuberculosis. New research had emerged that ultraviolet light, contained in the solar spectrum had antibacterial properties. Dr. Woloshyn makes a note that medical practitioners at the time were aware of various published experiments conducted by Louis Pasteur, Arthur Downes and Robert Koch which proved the antimicrobial characteris...

the effective doses from diagnostic CT procedures are typically estimated to be in the range of 1 to 10 mSv. This range is not much less than the lowest doses of 5 to 20 mSv estimated to have been received by some of the Japanese survivors of the atomic bombs. These survivors, who are estimated to have experienced doses slightly larger than those encountered in CT, have demonstrated a small but increased radiation-related excess relative risk for
Years later other scientists were also intrigued by the possibilities of penicillin and produced enough penicillin to prove that it was a useable antibiotic. The scientists from Great Britain were developing all of this during World War II, and unfortunately funding for their drug was unavailable due to the war. They decided to bring their concepts to the United States, and once enough was made, it was eventually used, to treat wounded soldiers during World War I.
Mycobacterium tuberculosis (MT) is a slender, rod-shaped, aerobic bacillus which causes tuberculosis. Tuberculosis (TB) is an airborn infection which is transmitted via inhaling droplet nuclei circulating in the air. These droplets are expelled from the respiratory secretion of people who have active TB through coughing, sneezing, and talking (Porth, 2011). Some bacilli stay in the upper airway and are swept out by mucus-secreting goblet cells and cilia on the surface of the airway. Others will escape from this protective mechanism to travel and settle down at alveoli (Porth, 2011). Local inflammatory reaction occurs and macrophages are cells that act as next line defense mechanism to fight with mycobacteria. First they engulf micobacteria, try to reduce their strength and ability, and kill them. In the same way they send antigen to helper T lymphocytes to initiate a cell-mediated immune response (Knechel, 2009). The infected macrophages will send produced cytokines and enzymes to breakdown mycobacteria’s protein. It is the released cytokines that attract T ly...
At this day in age we are constantly trying to improve the field of medicine in any way that we possibly can. We cherish every birthday and continually try to prolong life. Not only through every field of medicine, especially in terms of cancer. The American Cancer Society is “the official sponsor of birthdays” and is making leaps and bounds in the types of care that cancer patients receive. One of these many breakthroughs is the practice of Stereotactic (Body) Radiotherapy or S(B)RT. SBRT and other radiation therapies have the ability to greatly improve the way that we treat the issue of cancer and the variation of treatment options; however, they have raised the concerns of long term effects from radiation and cost-effectiveness. As research has begun to show, radiation therapies are having great success in curing cancer.
Symptoms of tuberculosis include: coughing, chest pains, fatigue, fever, unintentional weight loss, etc . . .
Tuberculosis or TB, referred to by some as the White death due to the epidemic that arose in Europe that lasted two hundred years, is usually caused by in humans by a microorganism by substrains of Mycobacterium tuberculosis. It’s hard to determine the exact years in which TB first infected humans, but since the disease leaves traces on the bone in can be found in archeological record and it is believed to go all the way back to the B.C. era. Although it is hard to tell if the bone damage was truly from TB, there is research that shows that it has been around since the 17th and 18th centuries with a high number of incidences of TB, and in 1882 Dr. Robert Koch announced that his discovery of the causing factor of TB, which is Mycobacterium tuberculosis. A tuberculosis bacterium is spread through the air by an infected person speaking, coughing, or sneezing. Due to the fact the bacteria is protected by a waxy cell all, the body’s defense takes weeks to develop any kind of immunity and it allows the bacteria to exponentially multiply freely within the body. If TB it’s left untreated it will eat rapidly through many tissues, usually beginning with the lungs, lymph nodes, and kidneys. As the infection spreads to the lungs, it causes a cough and fluid between the chest wall and lungs, which leads to chest pains, severe shortness of breath, and potential heart failure. TB also infects bones and joints that can produce arthritis like pain and characteristic bone damage. Another possibility is that it may affect the fluid around the brain, causing meningitis, which can lead to fever, drowsiness, and eventually coma and death (Wingerson, 2009).
My hypothesis on Tuberculosis is that it is a very deadly disease that causes a persons lungs to fill with blood. This can harm the body by making the body suffocate itself when the lungs fill with blood.

Myobaterium tuberculosis is a nonmoving, slow-growing, acid-fast rod transmitted via aerosolization (airborne route). People who are most often infected are those having repeated close contact with an infectious person who has not yet been diagnosed with TB (Ignatavicius and Workman, 2006). Therefore, when a person with active TB coughs, sneeze, laughs, sings, or whistles, droplet become air borne and may be inhaled by others. Far more people are infected with the bacillus than actually develop active TB. The bacillus multiplies freely when it reaches a susceptible site (bronchi or alveoli). The majority of the bacilli are trapped in the upper parts of the airways where the mucus-secreting goblet cells exist. An exudative response occurs, causing a nonspecific pneumonitis (Ignatavicius and Workman, 2006). With the development of acquired immunity, further growth of bacilli is controlled in most initial lesions. Bacilli can also spread by erosion of the caseating lesions into the lung airways -and the host becomes infectious to others. Cell-mediated immunity develops 2 to 10 weeks after infection and is manifested by a positive reaction to a tuberculin test. Skin testing for tuberculosis is useful test to detect. According to Universi...
Tuberculosis or known as TB remains a leading cause of morbidity and mortality in the world, especially in developing countries. A combination of factors including high costs, limited resources and the poor performance of various diagnostic tests make the diagnosis of TB difficult in developing countries. According to Centers for Disease Control and Prevention (2014), one third of the world’s population is infected with tuberculosis. In 2012, nearly nine million people around the world become sick with tuberculosis disease, and there were around one point three million TB related deaths worldwide.
The name Tuberculosis derives from ‘tubercles’, which are present in the lymph nodes of affected animals.
Tuberculosis is an air-borne disease, hence, it can be passed from an infected person to a healthy individual through coughing, sneezing and other salivary secretions. Tuberculosis is caused by the transfer of Mycobacteriun Tuberculosis (M. Tuberculosis) also known as Tubercle Bacillus, a small particle of 1-5 microns in diameter, due to the small size, when an infected person sneezes or coughs, about 3,000 particles are expelled. M. Tuberculosis responsible for tuberculosis is able to stay in the air for a long period of time (about 6hoursAnother way of acquiring Tuberculosis is by drinking unpasteurized milk, milk straight from cow, although this is not a common mode of transmission, it can be found in rural areas. Ingestion of contaminated cow milk transmits Mycobacterium Bovis, the animal form which is still potent enough to cause tuberculosis in humans. ). Tuberculosis transmission is affected by exposure, socioeconomic status of person, proximity, immune status of uninfected individual (%&&%&? CDC).
Its epidemiological importance is illustrated by World Health Organization Prevention of Tuberculosis includes better living conditions, proper nutrition, and positive health practices” (Fogel, 2015, p.530). Positive health practices include covering nose and mouth when coughing and frequent hand washing. Bacille Calmette-Gurin (BCG) vaccine tends to be given in other countries. Tuberculosis is known as one of the main causes of mortality in the world. This communicable disease is a serious public health conundrum. “The disease still puts a strain on public health, being only second to HIV/AIDS in causing high mortality rates” (Matteelli, Roggi, & Carvalho, 2014, p.
Tuberculosis is transmitted by inhalation of aerosols containing the tubercle bacilli. The required inoculum size for infection is usually high, but easily occurs with exposure to a patient who is currently infected. The products of dried aerosols, droplet nuclei, are particularly infectious because they remain in the air for an extended time, and upon inhalation easily move to the alveoli. The severe damage related to infection is caused by the reaction of the host. The tuberculosis infection has two phases, primary and secondary.
