banks of eastern Kentucky's Troublesome Creek. Martin Fugate, a French orphan settled in Troublesome Creek and astonishingly Martin somehow managed to find a woman who carried the same, very rare disease. The disease, later discovered, was methemoglobinemia, a very rare heredity blood disorder caused by an inheritance of a gene as a simple recessive allele. What one wonders after hearing ?blue people? is if they were actually really blue in color? Well the answer is yes and no. Some of these
Methemoglobin: An Unlikely Explanation for Cyanosis Methemoglobinemia is an uncommon but possible reason for cyanosis. Methemoglobinemia is significant because the disease is fairly rare and consequently most physicians do not consider it as a cause when diagnosing a patient with cyanosis. Regrettably, patients often get misdiagnosed and sometimes treated for the wrong disorder as a result. A two fold dilemma occurs when the patient is treated for an incorrect disorder. The first part of the dilemma

Excess nitrogen in water has been linked to methemoglobinemia, a condition where increased levels of methemoglobin are present in the blood preventing oxygen to be carried throughout the body. Methemoglobinemia is potentially lethal to infants. Along with nitrogen, phosphorus indirectly can harm human health. Phosphorus is a catalyst for toxic algal growth. A study from Sarasota
Blue baby Case Study Cyanosis is a disorder which causes “bluish discoloration” to the skin, specifically around the mucus membranes or nail beds. There are two types of Cyanosis disorders, depending on where the cyanotic discoloration is occurring. For example, if the cyanotic discoloration is occurring around the nasal or oral tissue membranes, this type of cyanosis would be described as Central Cyanosis. In the same matter, if the bluish discoloration is occurring in extremities such as toes
Nitrogen is used by plants in order to synthesize protein peptide bonds and for cell growth. Not only is this nutrient required in the largest quantity by plants, but it is also the most frequently limiting factor when it comes to productivity in crops. Plants cannot use nitrogen in the air and in the soil system it is lost easily. Because of this plants are forced to obtain nitrogen in the form of nitrate and ammonium from the soil. Too much nitrate can cause a negative effect on the plant including
Many people use mothballs for different reasons. Mothballs are helpful for many different causes, but health risks are also associated with mothballs. Using mothballs can repel moths and make things smell great, but can also cause hemolytic anemia. Mothballs are helpful in many ways, but there is one factor in mothballs, Naphthalene, that can cause health issues. Mothballs have many features that are beneficial to people. One feature of mothballs is keeping a house or building free of pest. Mothballs
ag. runoff is also often attributed to the contamination of surface and well-water sources in rural areas. High levels of nitrates restrict the ability of red blood cells to carry oxygen. This can harm humans, and is the major cause of infant methemoglobinemia, or “blue baby syndrome”. The safe drinking level standard is 10mg/L. Nitrogen and nitrates relate to Hypoxia via the process of eutrophication. Since Nitrogen is a limiting nutrient in most waters, the added input of nitrate causes massive growth
Iron is an enigma of sorts, from constructing large buildings with it to helping the flow of oxygen through your body. Iron is a metal that provides for both the material and physical aspects in everyday life. The Eiffel Tower, the Statue of Liberty, and the Capitol are only a few structures that are constructed with iron. It is widely versatile, and is one of the cheapest and strongest metals that made it indispensable during the Industrial Revolution. Not only that, but it can also be combined
When you think of problems in the world today, water pollution isn’t one that would normally come up. In fact it is one of the worst problems in the world today. Water pollution, by definition, is the contamination of streams, lakes, underground water, bays, or oceans by any substances harmful to living things. All living things contain water and most need water to survive, so water pollution is a big problem. If severe, the pollution can kill off birds, fish, and any animals that use the water source
is a toxic and combustible substance, which can enter into the human body through various routes such as inhalation, ingestion and most commonly absorbed through the skin( dermal) and its health effect includes neurological effect, hepatic, methemoglobinemia, dermatitis, irritation of the eyes etc. It causes damages to organs such as the skin, eyes, cardiovascular and reproductive systems. It is suspected to be carcinogenic but no sufficient data to prove it. Question 2 • In the petroleum refining
(Eagans, 2013) NO is also said to be linked with direct cellular damage even when given in low doses. Some side effects of NO include blurred vision, confusion, dizziness, sweating, chest discomfort, tightness in the chest, trouble breathing, methemoglobinemia, hypotension, atelectasis, stridor, and hyperglycemia (Drugs.com, 2015). NO can be used for a quick reduction in right ventricular afterload which may cause an increase left ventricular filling pressure in some cases (Eagans, 2013). A lot of
Chemical Control Agents Used Against the Gypsy Moth The gypsy moth (Lymantria dispar) is a highly disruptive species that can, and has played a distinctive role in the lives of many organisms. Included in these organisms are various deciduous trees and shrubs, wildlife species that share the same environment, and even humans. The gypsy moth destroys the beauty of woodlands via defoliation, alters ecosystems and wildlife habitats, and disrupts our own lives. It should therefore come as no surprise
down throughout generations of inbreeding and close relations of several families. The remoteness of the “colony” of blue people had an effect on why this spread to so many people, and not just a few. The actually deficiency itself was called methemoglobinemia, and was an enzyme defect. Doctor Cawein was the one to actually discover and treat the defect, and make the people of troublesome creek no longer blue but pink. Martin Fugate was a man of blue color, he moved to America and claimed some land;
nitrate is usually low with less than 2 ppm. Meanwhile, the maximum contaminant level goal (MCLG) and local limit is 10 ppm. If the concentration of nitrate in a body of water exceeds 10 ppm, it can cause health problems for humans, such as methemoglobinemia, and a spike in the growth of plant life, such as algae blooms. As for the amount of phosphate, there is an even lower natural concentration with 0.05 ppm and 0.1 ppm for the local limit. Similar to an excess amount of nitrate, a higher presence
Setting of “The Cask of Amontillado” The setting is an important part of any story, whether it be a poem or a novel. The setting consists of all the places and/or things surrounding the character at any moment through any literary or visual media. A literary setting is often full of details and vivid imagery due to the lack of visual aids that are present in videos and movies. These details often take paragraphs to describe single settings to give the reader an imaginary vision of what the area would
Today, chemical fertilizers are used worldwide on people’s crops and other plants. One may ask, what is chemical fertilizer and how does it contribute to our environment? To start with, crops need a number of nutrients to survive like nitrogen, sulfur, and phosphorous for their growth. Overtime, soil nutrients decrease because the crops are harvested or they die. The nutrients do not come back to the soil until the crop decomposes so when you add fertilizer, the process is sped up and plants grow
Knowing the specifics about organic foods will help a person determine whether they would prefer to eat organically or non-organically. The term ‘organic’ is a label that indicates that the food has been produced through the appropriate approval methods (“Organic Standards”). There are certain requirements that must be met by the USDA-accredited certifying agent. This certifying agent approves these requirements before the food can be labeled as an organic food. Organic operations must protect natural
I was in our school’s quiet area about between five or six months ago just relaxing until my class began, so I picked up some magazines like usual do. I’ve already read most of magazines I liked, so I found a new one called Endeavors and I alerted me to a problem that I never thought about before that happens in our very own state. So, before I begin, can I ask how many people know anything about the pork industry? Personally, the problems I’ve seen before on television or other media outlets never
collects in the ground water and in surface streams. This can cause eutrophication, an excess growth of plants and algae, in nearby streams and lakes (Weil, et al, 441). Also, concentrations of nitrate of 10 mg/L or more in drinking water can cause methemoglobinemia, or blue baby syndrome in infants (Hubbard, 802). In well-drained soils, organic material, which, of course, contains nitrogen, "may decompose faster than it is replenished (Dolman and Bud, 1967)" (Gambrell, et al, 321). So, in order to s
