This then results in inflammation and swelling and infections. This faulty gene has to be inherited by both parents to develop cystic fibrosis, but it is still a relatively common genetic condition as it is estimated that 1 person in every 25 carries the faulty CFTR gene. When both parents’ carries the gene there is a one in four chance that the child will not inherit either of the faulty genes and will not be a carrier of the condition. There’s also a one in two chance that the child will inherit only one of the faulty genes from one of their parents instead of both of them which would mean that they would not have cystic fibrosis, but they would be a carrier of the condition. Finally, there is also a one in four chance that the child will inherit both copies of the faulty gene which would mean that the child would have cystic fibrosis. Downs syndrome The cause of Down syndrome is that it is a genetic condition which occurs when an extra copy of chromosome 21 is present. Chromosome 21 causes physical and developmental characteristics associated with Down syndrome which is due to the additional genetic material. Chromosomes are blocks of DNA which contain a range of detailed genetic instructions which control a number of factors within the human body such as how the body’s cells develop, eye-colour and the sex of a baby...

...Definition; Meningitis is an inflammation of the membranes (meninges) surrounding your brain and spinal cord. It’s easy to mistake the early signs and symptoms of meningitis for the flu (influenza). Meningitis signs and symptoms may develop over several hours or over one or two days. Signs and Symptoms; The signs and symptoms that may occur in anyone older than age of 2 include: • Sudden high fever • Severe headache that isn't easily confused with other types of headache • Stiff neck • Vomiting or nausea with headache • Confusion or difficulty concentrating • Seizures • Sleepiness or difficulty waking up • Sensitivity to light • Lack of interest in drinking and eating • Skin rash in some cases, such as in meningococcal meningitis Signs and symptoms in Newborns; Newborns and infants may not have the classic signs and symptoms of headache and stiff neck. Instead, signs of meningitis in this age group may include: • High fever • Constant crying • Excessive sleepiness or irritability • Inactivity or sluggishness • Poor feeding • A bulge in the soft spot on top of a baby's head (fontanel) • Stiffness in a baby's body and neck Infants with meningitis may be difficult to comfort, and may even cry harder when picked up. Causes; Meningitis usually results from a viral infection, but the cause may also be a bacterial infection. Less commonly, a fungal infection may cause meningitis. Because bacterial infections are the most serious and can be life-threatening...

...of Diseases and How They Cause Deafness For Adults One of the most common diseases that can cause hearing loss is called Otosclerosis. Otosclerosis is a condition caused by an unusual bone remodeling in the middle ear. During Otosclerosis, this remodeling process disrupts the ability of sound to travel from the middle ear to the inner ear. This disease typically causes conductive hearing loss, which occurs when sound is not conducted efficiently or effectively through the outer ear canal to the eardrum and the ossicles of the middle ear. This disease affects more than three million people in the United States, and in most cases, Otosclerosis is passed down from parents. Another common disease that causes deafness is Vertigo. Vertigo can be one of two ways, peripheral or central. Peripheral vertigo is the cause of deafness. This is due to a problem found within the inner ear. Vertigo occurs when the inner ear becomes inflamed because of illness, small crystals, or stones typically found within the inner ear, which can cause irritation to the small hair cells found deep within the inner ear. One disease that goes hand in hand with Vertigo is Meniere's...

...Just as this main tower directs and controls all incoming and outgoing flights. The central nervous system is the control center of our body, it sends information out and interprets things our body senses. Regulating, controlling and coordinating incoming and outgoing impulses, thoughts, and feelings via nerves. Functionally, the nervous system can be divided into the central nervous system (controls in-bound and out-bound neural impulses), and peripheral nervous system (connects the CNS with the peripheral parts of the body). The PNS can be divided into subdivisions of the somatic nervous system (deals with the parts of the body we move voluntarily) and autonomic nervous system (works with the involuntary parts of the body). The CNS receives sensory input from the peripheral nervous system and produces motor responses via nerves. A nerve is a fiber composed of nerve cells and neurons. Most nerves of the peripheral nervous system contain both sensory neurons and motor neurons. The sensory neurons in the peripheral nerve carry sensory impulses to the CNS. The CNS processes this information and sends the appropriate motor signals back to the nerves via the motor neurons. (Terfera, D. & Jegtvig, S., 2015). The brain and spinal cord is what makes up the central nervous system. The brain being the command center controlling the body functions of sending and receiving messages through the nerves. At the end of each nerve cell, there is a synaptic terminal thus full of...

There are different types of meningitis, but most are caused by viruses or bacteria. Viral meningitis can make you very sick but it often doesn’t have lingering effects. Bacterial meningitis is more serious. It progresses rapidly and can cause permanent damage or even become life-threatening. CT scans of the head may reveal swelling or inflammation. These tests can also help your doctor look for infection in other areas of the body that may be associated with meningitis. Spinal tap (lumbar puncture). The definitive diagnosis of meningitis requires an analysis of your cerebrospinal fluid (CSF), which is collected during a procedure known as a spinal tap. In people with meningitis, the CSF fluid often shows a low sugar (glucose) level along with an increased white blood cell count and increased protein. CSF analysis may also help your doctor identify the exact bacterium that causing meningitis. 2. Memory: repeating statements and questions over and over, not...

...the thousands of species of fungi, a few can cause human disease. These fungi cause a wide range of illnesses, from minor skin conditions to life-threatening diseases. They produce two kinds of infections: systemic and superficial. Systemic infections affect internal organs. They often start in the lungs, but in severe cases may spread to the blood, heart, brain, kidneys, liver, or other parts of the body. Superficial infections affect the surface of the body, the skin, the nails, and the hair. They most often occur in moist areas, such as between the toes, in the crotch, or in the mouth. Fungal diseases are called mycoses and those affecting humans can be divided into four groups based on the level of penetration into the body tissues. Superficial mycoses are caused by fungi that grow on the surface of the skin or hair. Cutaneous mycoses or dermatomycoses include such infections as athlete's foot and ringworm, where growth occurs only in the superficial layers of skin, nails, or hair. Subcutaneous mycoses penetrate below the skin to involve the subcutaneous, connective, and ne tissue. Systemic or deep mycoses are able to infect internal organs and become widely disseminated throughout the body. This type is often fatal. How common are fungal diseases? Treating and caring for patients with fungal diseases is becoming an increasing economic burden. Estimated numbers of patients who will need expensive antifungal drugs for some of the life-threatening fungal illnesses are...

...Mysterious Listeriosis Sara Williams Health Science Technology 3/4/2016 Mysterious Listeriosis Listeriosis is a foodborne disease, also known as food poisoning. Listeria is a bacterium that is mostly found in raw food, water, and animals (Rowland and Frey, 2015). You can get listeriosis by eating/drinking food or water that is contaminated with the bacteria. This disease is important because we need food and water to live, and we also have so many different varieties of how to eat it. Knowing about Listeria is highly beneficial because you never know how your food has been processed. Listeria is dangerous because it can affect anyone and can be in anything(Rowland and Frey, 2015). Pathophysiology A person can become infected with Listeria by simply eating contaminated food. Such as, raw vegetables, fish, poultry, raw (unpasteurized) milk, fresh meat, processed meat, and some cheeses. Something that makes Listeria unique is that...

...INTRODUCTION Review of Related Literature Pneumonitis Pneumonitis is a general term that refers to inflammation of lung tissue. It occurs when some irritating substance – solid particles, liquids, gases, radiation or bacteria – cause the tiny air sacs to become inflamed. This can hamper the exchange of oxygen and carbon dioxide in the air sacs. Pneumonia is one type of pneumonitis caused by an infection. There are several types of pneumonitis. They include: • Aspiration pneumonitis- occurs when you inhale (aspirate) foreign matter into your lungs. Stomach contents, such as ingested food or liquid, are a frequent cause of aspiration pneuomonitis. Accidental inhalation of small particles, such as tiny pieces of peanuts or vegetables, while swallowing is common in young children. • Chemical pneumonitis- is a type of aspiration pneumonitis that develops when you inhale chemicals that are toxic to your lungs. Industrial and household chemicals, such as chlorine gas, ammonia, solvents and pesticides can all cause chemical pneumonitis. • Hypersensitivity pneumonitis- is nicknamed “farmer’s lung,” “mushroom picker’s disease” and other colorful names with good reason. Dust from animal dander, molds and plants, all potential allergens, can provoke an inflammatory reaction in your lungs. Symptoms usually develop within six hours of exposure to the allergen. Some people are more susceptible to developing hypersensitivity pneumonitis than are others, although it’s...

...Explain how Vitamin D, calcidiol, and calcitriol are synthesized? The synthesizing process of vitamin D starts by ultra violet light converting 7-dehydrocholerol to vitamin D3. Next binding proteins come in and carry D2 and D3 vitamins to the liver to be converted to calcidiol. Then the enzyme 1-alpha hydroxylase converts calcidiol to 25 dihydroxy vitamin D. Calcitriol binds to the intracellular vitamin D steroid receptor to influence transcription of multiple genes. 4. How could George’s missing kidney be related to his decreased bone strength? The missing kidney decreases the body’s ability to convert calcidiol to calcitriol and reduces the ability to reabsorb calcium ions. One is just not as good as two. 5. How could George’s partial small intestine be related to his decreased bone strength? The small intestine is not able to absorb enough nutrients to sufficiently cover his body’s needs. 6. If George has a decreasing density of his bones due to his previous injuries, what is the classification of his condition? Osteoporosis would be the classification. 7. Could George’s lack of time outside be a factor in his weak bones? Yes because the skin can absorb vitamin D from the sun. This is much easier for the body than absorbing vitamin D from food, especially in George’s...

...diseases that people with normal immune systems can also get, but with HIV they occur at a much higher rate. It also takes longer for a person with HIV to recover than it takes for someone with a healthy immune system. When the immune system is very weak due to advanced HIV disease or AIDS, opportunistic infections such as PCP, toxoplasmosis and cryptococcosis develop. Some infections can spread to a number of different organs, which is known as 'disseminated' or 'systemic' disease. Many of the opportunistic infections that occur at this late stage can be fatal. 1 back to top Why is there still a need to prevent and treat opportunistic infections?

...2014 Wendy Armstrong In this paper I will be discussing what toxicants are and how they affect living organisms. I will also cover disease-causing agents and how they are transmitted. Last but not least I will go over how changes in the environment contribute to human diseases and are linked by human activities. Environmental hazards affect human population in many ways and we must be aware of the problems. Toxicants are man-made (synthetic) substances that present a risk of death, disease, injury, or birth defects in living organisms through absorption, ingestion, inhalation, or by altering the organism’s environment ("What Is Toxicant?", 2014). Toxicants are made by humans while toxins are produced naturally by living organisms. Examples of toxicants are pesticide, chlorine, asbestos, and mold. Toxicants can affect living organisms in many ways. One way that toxicants can affect living organisms is by killing off marine life. If the substance gets into the water it can cause fish and invertebrates to start to die. It can also include a change in the abundance, structure and variety of biological communities and habitats. The fish can also cause health risks to consumers of those organisms. The next things I will discuss are disease-causing agents. A disease causing agent is often referred to as a pathogen. A pathogen, such as a virus or a strain of bacteria can enter the body and cause a host of symptoms. Many times, these symptoms collectively indicate the presence...
