Disease Control Essay

… 5. Lateral gene transfer is very common among bacteria.

a. Describe 3 mechanisms of lateral gene transfer.

i. Transformation: genetic alteration of a cell

ii. Transduction: bacterial DNA is moved from one bacteria to another iii. Conjugation: bacteria transfers genetic material to another cell through contact

b. How can lateral gene transfer be beneficial to bacteria?

This process allows bacteria to respond and adapt to their environments more rapidly by acquiring larger DNA sequences from other bacteria.

c. How can lateral gene transfer complicate the study of phylogenetic relationships among bacteria & possibly the 3 domain system?

DNA becomes mixed between different bacteria and therefore the individual genetic material can become complicated, making it difficult to understand the clear differences between organisms.

6. Woese's studies led to the 3 domain system that replaced the 5 kingdom system.

a. Why did the 5 kingdom system become "obsolete"?

Protista, fungi, plantea, and animalea have all been placed under the category eukarya while bacteria are so diverse that they have required their own classification.

b. Discuss why nucleotide sequencing of ribosomal RNA has been useful in evolutionary biology.

Since RNA sequences differ between species due to mutations, biologists can examine the nucleotide sequence and determine potential connections between species which are no longer similar but may have a shared evolutionary ancestor.

c. Name a few unexpected outcomes of Woese's studies & 3 domain system.

i. Organisms originally given their own kingdom have been linked and shown to be genetically close

ii. Easier to determine a common ancestor iii. Determination of niche role of organisms.

d. Name some similarities that have been retained by members of the 3 domains of life that clearly indicate their common (but ancient) ancestry.

i. Similar genetic codes

ii. Evidence of prokaryotic vs. eukaryotic cells iii. Evidence of evolution and adaptation.

7. Viruses are not cellular & thus not considered to be living organisms.

a. Give 4 reasons for studying viruses in biology courses despite the above.

i. They interact with living things

ii. Viruses have genetic information and can reproduce iii. Viruses are found in nearly every ecosystem on earth

iv. Immunizations can be made from viral material

b. The origin of viruses is subject to the same common dilemma of: "who came first, the chicken or the egg?" Discuss some evidence from molecular studies that would help you resolve the dilemma around the origin of viruses (did viruses or cells evolve first?)

Periodontal Disease and Respiratory Essay

… Moreover, the authors note that all three of the diseases in question (periodontal, pneumonia, and COPD) are "complex, multifactorial, and have many risk factors," (p. 7). Some of the potential intervening variables include smoking status, medical history, age, dental caries, missing teeth, dysphagia, and low socio-economic status (p. 7).

Low socio-economic status is something that practitioners should be taking into account when treating patients. The authors point out that, "Canadians living in urban, low socioeconomic areas are 2.7 times more likely to be hospitalized from COPD than those in higher socioeconomic areas," (p. 3). Age and physical condition is also a factor that practitioners need to take into account. This is especially true with regards to aspiration pneumonia, which can be caused "when food or liquids from the mouth, gastric contents, or oropharyngeal secretions are inadvertently inhaled into the lower respiratory tract," (p. 3). The elderly or infirm dependent on external feeding mechanisms or who are missing teeth might be particularly susceptible. The authors note that elderly living in long-term care facilities are also to be classified as a high-risk community. In fact, there are several identifiable mechanisms by which oral bacteria can precipitate or cause a respiratory infection. High risk communities, including the elderly and people who smoke, should be examined more closely by dentists due to the potentially debilitating if not fatal impact of developing a respiratory illness. Even if there is no direct causal relationship, the literature does support a general concern for these risk factors.

Inadequate oral hygiene is another potential precipitating factor. Although no direct causal relationship can be revealed, poor oral remains a major risk factor for at least periodontal disease. The presence of oral bacteria due to poor oral hygiene is likely to exacerbate pre-existing tendencies to develop respiratory infections. Therefore, it is important to promote oral hygiene in general to prevent the build up of bacteria that could lead to or exacerbate an existing respiratory condition.

Community-based oral hygiene programs are a good way of raising awareness about the risk factors related to respiratory disease and periodontal disease. The community health programs can highlight the consequences of poor oral hygiene, and the consequences of contracting a respiratory illness. Because many of the highest risk populations are seniors living in long-term care facilities, who may have dependency on nurses for feeding and oral care, it is also critical to target nursing homes and senior care facilities. For instance, the dentist and hygienists need to know if the patient uses mechanical ventilation or tube feeding tubes. Educating caregivers about the importance of oral hygiene for elderly patients will help reduce the problems associated with both periodontal disease and respiratory illnesses.

It has been postulated that, "one in ten deaths from pneumonia in dependent elderly may be prevented by improving oral hygiene," (p. 8). Therefore, prevention and intervention are critical factors for an oral hygiene practice. Practices should take into account patient history regarding respiratory illness, smoking status, and age-related issues such as feeding dependencies.… [read more]

Osteoarthritis Victims of Intimate Violence Research Paper

… In diagnosing the disease, medical practitioners apply methods such as physical examination, x-ray, lab tests, and medical history. Following the diagnosis process, it is essential to adopt and implement effective methods for the management of the disease. This relates to incorporation of drug therapy, surgical measures, and physical mechanisms in the minimization of the conditions of the disease. These methods are essential in the minimization of pain and stiffness of the joints thus enhancing the mobility of the affected individuals.

Occupational Health and Safety Research Paper

… " (World Health Organization, 1995, p.1) The World Health Organization document entitled "Global Strategy on Occupational Health for All: The Way to Health at Work" reports that necessary are goals for preparing, developing, and strengthening the "…necessary infrastructures, information systems and awareness of the needs and possibilities of occupational health activities, development of occupational health services for all working people, and building up the necessary sup-port services and human resources needed for implementing the new Strategy." (1995, p.1)

The International Labor Organization reports that work-related accidents and diseases are both very expensive with "many serious direct and indirect effects on the lives of workers and their families." (2011, p.1) Some of the direct costs for workers include:

(1) the pain and suffering of the injury or illness;

(2) the loss of income;

(3) the possible loss of a job; and (4) health-care costs. (International Labor Organziation, 2011, p.1)

Reported as costs to employers of occupational accidents and illnesses are the following stated direct costs:

(1) payment for work not performed;

(2) medical and compensation payments;

(3) repair or replacement of damaged machinery and equipment;

(4) reduction or a temporary halt in production;

(5) increased training expenses and administration costs;

(6) possible reduction in the quality of work;

(7) negative effect on morale in other workers. (International Labor Organization, 2011, p.1)

Summary and Conclusion

It is imperative that employees and employers alike understand occupational health and safety regulations and adhere to these to avoid injury, disease and associated costs to both the employer and employee when the health and safety rules and regulations are not followed.

Sexually Transmitted Diseases Syphilis Essay

… ("Genital Herpes - CDC Factsheet") Between outbreaks, when sores and blisters are not present, the viruses can also be transferred from person to person through the skin. Pregnant women can also transmit this disease to their unborn children and should be careful not to contract the disease during pregnancy. While there can be psychological trauma associated with contracting the disease, the most common affects of Genital Herpes are painful sores on the genital and rectal areas which recur over time. Like Syphilis, the best way to avoid Genital Herpes is to avoid sexual contact with infected persons, but the use of condoms has also been demonstrated to reduce the risk of infection.

If a person is already infected with a sexually transmitted disease (STD), they are between two and five times more likely contract the AIDS, or HIV, virus. ("The Role of STD Detection.") Like both Syphilis and Genital Herpes, AIDS is also transmitted through sexual contact. As a virus, HIV is easily spread through secretions, particularly genital secretions, and is often associated with other STD's. For example, genital sores resulting from Syphilis or Genital Herpes, often result in breaks in the skin or the genital lining. This can provide both an excellent point of entry for the HIV virus, or a perfect way to infect another person. When infected, early signs often resemble the flu; fever, headache, fatigue, and swelling in lymph nodes. ("The Role of STD Detection") But as the disease progresses, symptoms can include weight loss, skin conditions such as blisters and sores, secondary infections like chicken pox or pneumonia, periodontal disease, dementia, brain tumors, and other neurological complications. ("The Role of STD Detection") As with both Syphilis and Genital Herpes, both avoiding sexual contact with the infected, and the use of condoms can reduce the chance of contracting the disease.

Periodontal Disease and Pregnancy Research Paper

… The effective management of the large pyogenic granumola coupled with the treatment of periodontal inflammation before pregnancy helps in controlling periodontitis and gingivitis. While small pyogenic granumolas may disappear suddenly, large lesions require treatment through surgery, lasers, electrocautery, and freezing. However, the most common way for treating the unusual large pyogenic granumolas is through surgical therapy or excision.


Periodontal disease is a disease that affects the structures of the teeth and can cause adverse pregnancy outcomes like pre-term birth. This disease can be prevented and controlled through promotion of good oral health or hygiene and management of pyogenic granumola.

Alzheimer's Disease Essay

… Treatment

No cure exists for Alzheimer's disease. However, research indicates that certain lifestyle factors can have a formidable impact in preventing the illness. Individuals who engage in regular physical activity are 50% less likely to develop the disease, a rate which increases to 60% for women who exercise (Peeke 2004: 8). Regular use of non-steroidal anti-inflammatory drugs (NSAIDs) like aspirin or ibuprofen has also been correlated with lower rates of the illness: a 35% reduction in the in one study. Maintaining a healthy weight; engaging in sustained mental activity; and eating many fruits and vegetables high in antioxidants, fish high in omega-3 fatty acids, and nuts have all been linked to lower rates of Alzheimer's. Diet and exercise, along with a low-dose aspirin regime, may reduce the risk because of their anti-inflammatory properties. "One study of elderly women showed that those who ate the most green, leafy and cruciferous vegetables (spinach, kale, and dark salad greens) had the thinking ability of slightly younger women than those who ate few of these vegetables" (Peeke 2004: 8).

Consuming foods high in cholesterol have been linked to an increased likelihood of developing Alzheimer's. "Several studies have been published during the last years linking diet with the development of Alzheimer's disease and dementia and especially too much cholesterol have been found to be particularly bad. This is probably because the brain is an organ that is especially rich in cholesterol and where cholesterol has many functions, and therefore is tightly regulated" (Hills 2009: 38). The gene the most common gene variant associated with Alzheimer's ApoE4 "is found in 15-20% of the population" and is involved in the metabolism of cholesterol (Hills 2009: 28). "Mice that had been genetically modified to mimic the effects of ApoE4 in humans" showed "an increase in phosphate groups attached to tau, a substance that forms the neurofibrillary tangles observed in Alzheimer's patients, which prevents the cells from functioning normally and eventually leads to their death. They also saw indications that cholesterol in food reduced levels of another brain substance, Arc, a protein involved in memory storage" (Hills 2009: 28). High blood pressure has also been linked to a greater likelihood of developing the illness.

These findings regarding cholesterol and dietary factors that can affect the progression of the illness confirm what scientists have long suspected, that Alzheimer's is not caused by either nature or nurture in most subjects, particularly late-onset subjects, but rather is the result of a combination of genetic and environmental influences. Although a healthy diet, exercise, and cognitive stimulation cannot prevent Alzheimer's, these practices can possibly counteract some genetic tendencies to develop the disorder. No drug treatments have been shown to consistently slow the progression of Alzheimer's in all patients. "There is no strong evidence that Folate (vitamin B6), vitamin B12, and vitamin E prevent AD or slows the disease once it occurs," and "high-quality studies have not shown that ginkgo biloba lowers the chance of developing dementia" (Jasmin 2010).

Death and Disease Analysis for California

Cancer is a large collection of diseases that are distinguished by uncontrolled growth and spread of abnormal cells. If the disease is not controlled or kept in check, it consequences in death. However, many cancers can be cured if detected and treated quickly, and a lot of others can be prevented by lifestyle changes, particularly by avoiding tobacco use. Between 1988 and 2009, California saw overall cancer occurrence rates decrease by 11%. In this same time period, mortality rates went down by 23%. However, it is still estimated that in 2012 144,800 Californians will be diagnosed with cancer. This is equal to more than 16 new cases every hour of every day. It is estimated that 55,415 people will die of the disease next year, which works out to almost 150 people every day (California Cancer Facts & Figures, 2012).

In 2004-2008, the overall cancer occurrence rate in California was lower that than of the entire nation. "California cancer incidence rates for Asian/Pacific Islanders, African-Americans, and non-Hispanic whites were between one and three percent lower than the nation. Hispanics in California had a nearly 9% lower incidence rate than other Hispanics in the nation" (California Cancer Facts & Figures, 2012).

Doctors frequently cannot clarify why one person develops cancer and another does not. But research shows that certain risk factors augment the chance that a person will develop cancer. These are the most widespread risk factors for cancer: growing older, tobacco, sunlight, ionizing radiation, certain chemicals and other substances, some viruses and bacteria, certain hormones, family history of cancer, alcohol and poor diet, lack of physical activity, or being overweight. A lot of these risk factors can be avoided. Others, such as family… [read more]

Glycogen Storage Diseases Are Caused Research Paper

… , 2000). The structure of the catalytic unit (G6Pase) consists of a nine-transmembrane helical structure, with the N-terminus and four loops positioned on the ER luminal surface. One of these transmembrane sections is home to 25 missense mutations that cause GSD type Ia, suggesting the resulting amino acid changes and this transmembrane section are critical to the catalytic activity of G6Pase. Another disease-linked missense mutation is located in the N-terminus and the remaining seven missense mutations that have been identified are located in two of the four loops. The only regions not linked to disease-causing mutations are the cytoplasmic loops and one luminal loop.

Overall, the majority of GSD type Ia cases are the result of just three mutations: R83C, Q347X, and 727GT (Rake et a., 2000). All other mutations individually account for less than 5% of disease prevalence and some have only been found in one patient or family. The arginine to cysteine change that occurs in patients with the R83C mutation results in a G6Pase protein without detectable phosphohydrolase activity (Lei, Shelly, Pann, Sidbury, and Chou, 1993). The Q347X mutation results in the conversion of a glutamine codon to a stop codon, which truncates the carboxy terminal by 11 residues and completely destroys the catalytic activity of G6Pase (Lei, Pan, Shelly, Liu, and Chou, 1994). The 727GT mutation affects the splicing of exons 4 and 5, despite the retention of the wild-type splice sites, and results in a G6Pase protein truncated by 146 amino acids (Kajihara et al., 1995). Other mutations similarly have been shown to abolish or significantly… [read more]

Neuropathological Disorders Essay

… Psychology

Neuropathological Disorders

Amyotrophic Lateral Sclerosis, also known as Lou Gehrig's disease is a neurological disorder that causes steady deterioration of the body's nerves and muscles. The cause of the disease is not known, and it affects men and women on an equivalent basis. At first, a person with Lou Gehrig's disease will experience a lack of coordination and not being able to hold on to objects and trouble performing everyday tasks. They could also feel tiredness, along with muscle twitches and trouble speaking. Because the disease usually occurs in middle to older age, it is often confused with the normal aging process (Carlson, 2011).

As the disease advances, the person will have trouble walking. They may also lose the capability to control their hands, to the point where they can't dress or bath themselves. Eventually, they will need a motorized wheel chair for transportation because they will not be able to use a manual one. In the later stages of the disease as the muscles continue to atrophy, the person's nerve and muscle function will worsen to the point where they will need a ventilator to help them breathe. Paralysis will continue to spread throughout the body, and limb function will cease. A person may also be unable to chew or swallow (Carlson, 2011).

Approximately ninety percent of people with ALS do not have a family history of ALS in any closely related family members. In these people, the cause of ALS is complex, resulting from a mixture of both genetic and environmental variables. Genes involved in the non-familial form of ALS are occasionally called susceptibility genes because they augment the risk to get the disease. Susceptibility genes are believed to act together with other genes as well as the environment to cause ALS (Amyotrophic Lateral Sclerosis (ALS), 2005).

The remaining ten percent of people with ALS have the familial form of the disease, in which numerous family members are affected by ALS. The familial form of ALS includes both small families where as few as two family members have ALS to families with a lot of… [read more]

Hodgkin's lymphoma

Hodgkin's lymphoma

Hodgkin's lymphoma is the cancerous proliferation of a patient's lymphoid cells. The presence of Reed-Sternberg cells is a necessary precondition of the diagnosis of Hodgkin's lymphoma, although R-S cells are identified with other disorders. "The primary diagnosis of Hodgkin's lymphoma from the histopathologic examination of a lymph node requires the identification of Reed-Sternberg cells in an appropriate, reactive cellular background. If a diagnosis of HD has been established on lymph node biopsy, the criteria for diagnosis of extranodal sites can be relaxed - requiring only mononuclear R-S cells and their variants in an appropriate background- not classic bilobed R-S cells" (Lymphoma: Hodgkin's lymphoma (Part 1), 2010, University of Virginia). This is one reason why identification of R-S cells at the lymph nodes is so critical during the early diagnostic stages and not at extranodal sites, where R-S cells may not be present.

Hodgkin's lymphoma is divided into two major groups, the first of which is nodular lymphocyte predominant Hodgkin's lymphoma. The second type is classical Hodgkin's lymphoma, subdivided into nodular sclerosis classical Hodgkin's lymphoma; mixed cellularity classical Hodgkin's lymphoma; lymphocyte-rich classical Hodgkin's lymphoma; and lymphocyte-depleted classical Hodgkin's lymphoma. Nodular sclerosis classical Hodgkin's lymphoma is mainly manifested in women and lymphocyte-depleted classical Hodgkin's lymphoma is mainly manifested in AIDS patients (Lymphoma: Hodgkin's lymphoma (Part 2), 2010, University of Virginia). With lymphocyte-depleted classical Hodgkin's there are many R-S cell variants and most patients are at Stage III or Stage IV when diagnosed making their prognosis poor (Hemopathology, 2010, University of Utah). These latter types would be seen as unlikely suspects for the patient Mr. H.D.'s illness.

Mixed cellularity classical Hodgkin's lymphoma is more common in men (Lymphoma: Hodgkin's lymphoma (Part 2) 2010, University of Virginia). Prognosis of this type is fair, as most patients are at stage III when diagnosed (Hemopathology,… [read more]

Emerging Infectious Diseases Human Monkeypox Research Paper

… ¶ … Infectious Diseases: Human Monkeypox

Monkeypox is an uncommon viral illness that takes place typically in middle and western Africa. It is known as monkeypox since it was first discovered in 1958 in lab monkeys. Blood examinations of animals in Africa later established that other kinds of animals most likely had monkeypox. Scientists also discovered the virus that leads to monkeypox in an African squirrel. These kinds of squirrels might be the ordinary congregation for the disease, but rats, mice, and rabbits can get monkeypox, as well. Monkeypox was found in people for the first time in 1970 (What You Should Know about Monkeypox, 2008).

In early June 2003, monkeypox was reported in the midst of numerous people in the United States. The majority of these people got ill after coming into contact with pet prairie dogs that were ill with monkeypox. This is the primary instance that there has been an eruption of monkeypox in the United States. The illness occurs because of the Monkeypox virus. It belongs to a collection of diseases that comprises the smallpox virus (What You Should Know about Monkeypox, 2008).

In humans, the indications and symptoms of monkeypox are comparable to those of smallpox, but more often than not they are less. An additional variation is that monkeypox makes the lymph nodes to swell up. About twelve days after being contaminated with the virus, a person will get a muscle aches, fever, headache and backache. Their lymph nodes will swell and they will feel drained. One to three days after the fever begins, a person will get a rash. This rash turns into elevated bumps packed with liquid and often begins on the face and spreads, but it can begin on other areas of the body as well. The bumps go throughout numerous stages before they get hard, scab over, and go away. The sickness typically sticks around for two to four weeks (What You Should Know about Monkeypox, 2008).

Celiac Disease Term Paper

… Nutrition

Celiac Disease

What can you find out about the digestive system and nutrition?

The precise cause of celiac disease has still yet to be determined. The intestines contain projections which are known as villi. The function of villi is to take up nutrients. When celiac disease is not diagnosed or left untouched, these villi become compressed. This has an effect on the capability to absorb nutrients correctly. Taking away all harmful grains from one's diet is the greatest significant measure that one can do in order to get healthy and stay that way (Celiac disease -- sprue, 2010).

What can you learn about Celiac Disease?

Celiac disease is an ailment of the digestive system that harms the small intestine and hinders the uptake of nutrients that come from food. Patients who suffer from celiac disease are not able to endure gluten, which is a protein that is found in rye, wheat, and barley. Gluten is contained primarily in foods but can also be found in daily products such as drugs, vitamins, and lip balms. When patients who suffer from celiac disease eat foods or utilize things that include gluten, their immune system responds by damaging or harming villi. The function of villi is to permit nutrients from food to be captivated by way of the walls of the small intestine into the bloodstream. A patient who does not have strong villi can become malnourished, despite the amount of food that is consumed on a daily basis (Celiac Disease, 2008).

What can you see from tracking the effects of this condition?

Celiac disease if left untreated can become life threatening. Celiacs are further prone to be bothered with troubles connecting to malabsorption, comprising of osteoporosis, tooth enamel defects, central and peripheral nervous system disease, pancreatic disease, internal hemorrhaging, organ disorders such as liver, gall bladder, spleen and gynecological disorders. Untouched celiac disease has also been associated with an augmented danger of definite kinds of cancer, particularly that of intestinal lymphoma (FAQ, n.d.).

Parkinson's Disease

Parkinson's disease (PD) is a condition that is a disorder of the motor system . It results in a loss of dopamine-producing brain cells. The four main indicator of PD are tremor, or trembling in hands, arms, legs, jaw, and face; stiffness, or inflexibility of the limbs and trunk; or sluggishness of progression; and postural shakiness, or impaired balance and coordination. As these symptoms become more prominent, patients may have trouble walking, talking, or completing other simple tasks. PD typically affects people who are over the age of 50. Premature symptoms of PD are understated and occur gradually. In some people the disease progresses more quickly than in others (NINDS Parkinson's Disease Information Page, 2010).

As the disease advances, the shaking, or tremor, which affects the preponderance of PD patients may begin to interfere with daily activities. Other symptoms may consist of depression and other emotional changes that include difficulty in swallowing, chewing, and speaking; urinary troubles or constipation; skin problems; and trouble sleeping. There are presently no blood or laboratory tests that have been established to help in diagnosing sporadic PD. Therefore the diagnosis is founded on medical history and a neurological examination. The disease can be difficult to diagnose precisely. Doctors may sometimes want to do brain scans or laboratory tests in order to rule out other diseases (NINDS Parkinson's Disease Information Page, 2010).

There are many risk factors for Parkinson's disease. These include: age -young adults rarely experience Parkinson's disease. It normally begins in middle or late life, and the risk continues to increase with age, heredity - having a close relative with Parkinson's amplifies the chances that a person will also develop the disease, although their risk is still no higher than about four to six percent, sex -men are more likely to develop Parkinson's disease than women are and exposure to toxins - continuing exposure to herbicides and pesticides puts a person at slightly increased risk of Parkinson's (Parkinson's Disease, 2010).

Addison's Disease Research Paper

… Addison's disease is basically an endocrine disorder in which the normal functioning of the adrenalin gland is seriously affected. This disorder affects 1 in 100,000 people and occurs equally among men and women and across different age groups. [NIDDK] Among the important functions of the adrenal gland is the secretion of Cortisol and Aldosterone, two important hormones that are essential to regulate blood pressure, cardiovascular function, inflammatory response, as well as protein and carbohydrate metabolism of the body. Aldosterone belongs to a class of hormones known as mineralocorticoids and plays a big role in maintaining the potassium sodium balance in the body. This salt balance is critical to maintain healthy blood pressure. Since the kidneys require aldosterone for sodium absorption and potassium excretion aldosterone insufficiency critically affects the kidneys ability to regulate the salt balance in the body, which in turn affects the blood pressure. Also referred to differently as Hypocortisolism or chronic adrenal insufficiency this disorder is potentially fatal if left untreated. [NIDDK]

The main cause of Addison's disease is the underfunctioning of the adrenal gland. This maybe due to the damage to the adrenal cortex by the inflammatory response of autoimmune disorders, infections, or neoplasms of the adrenal gland. Of these, adrenal gland damage by autoimmune disorders is known to be the primary cause of Addison's disease. When normal cortisol synthesis is affected directly due to the adrenal gland dysfunction the disorder is termed as primary adrenal insufficiency. However, since cortisol secretion is also dependent on the performance of another endocrine gland, the pituitary gland, pituitary anomalies will also affect the adrenalin cortisol secretion. The pituitary gland secretes ACTH (adrenocorticotropin), the hormone that triggers the adrenal to secrete cortisol. The ACTH secretion by pituitary in turn is controlled by another hormone CRH (Corticotropin releasing hormone) that is secreted by the hypothalamus in response to stress. Thus insufficient production of CRH would affect ACTH production and consequently cortisol secretion by adrenalin. Tumor or any disease of the pituitary gland may thus affect the normal adrenalin functioning. This is known as secondary adrenalin deficiency. Also, sometimes, prolonged corticosteroid therapy and some specific drugs used for the treatment of fungal infections affect natural cortisol secretion. [AAFP]

The Typical symptoms of Addison's disease include fatigue, muscle weakness, appetite loss and severe weight loss. Also, some patients may have (low blood sugar) hypoglycemia, fainting and development of dark patches on the skin (hyperpigmentation). Loss… [read more]

Kidney Disease in Children Term Paper

… Kidney Disease Children

Although kidney diseases are rarer in children than they are among the adult population, they can cause serious life-threatening complications. About one or two out of every 100,000 children in the United States develop kidney disease in the United States each year (National Institutes of Health). That risk is higher for boys than it is for girls, as "boys are nearly twice as likely as girls to develop kidney failure from birth defects, polycystic kidney disease, or other hereditary diseases," (National Institutes of Health).

Kidney diseases in children are generally caused by genetic factors, although many of the symptoms can be alleviated via lifestyle changes and medications. A number of birth defects and other preexisting conditions can cause kidney disease. For example, a narrow urethra condition called posterior urethral valve obstruction is one of the urinary tract problems that can lead to more serious kidney complications. Some kidney problems are the result of inadequate organ development in the fetus ("Kidney Diseases in Childhood"). Narrowing or enlargement of one or both kidneys, a disease known as fetal hydronephrosis, can occur while the child is developing in the womb or in early childhood ("Some causes of kidney disease in children"). Infants and toddlers may also develop urinary tract infections, which are difficult to detect in young children and which can lead to kidney disease when left untreated ("Some causes of kidney disease in children"). Therefore, it is imperative to understand the warning signs and early indicators of kidney disease in infants and toddlers.

Detecting kidney diseases early helps parents and doctors administer treatments and encourage the child to follow dietary restrictions if necessary. Prenatal testing may be used to detect certain types of kidney disorders. Other kidney diseases can only be detected later, after the toddler or young child has manifested symptoms such as a urinary tract infection or high blood pressure ("Kidney Diseases in Childhood").

There are two basic types of kidney diseases in children: acute and… [read more]

How Does One Develop a Disease Resistant Personality? Thesis

… ¶ … Disease-Resistant Personality

The idea that human personality affects health, wellness, and disease is hardly new, dating back to Hippocrates, the author of the medical oath of ethics still governing the practice of modern medicine today (Selye, 1956). In the era of high-tech scientific research, substantial empirical evidence has corroborated the long-noted anecdotal observations that certain types of personalities and chronic behavioral responses to environmental stressors correspond to different degrees of susceptibility to a wide range of physiological ailments and diseases (Flannery & Flannery, 2006; Friedman, 1990). To a large extent, many medical conditions with bona fide physical symptoms and physiological effects are attributable either all or in part to psychological factors in the realm of personality in general and in the realm of response and coping mechanisms in relation to stress in particular.


Renowned physician and author John E. Sarno has published a considerable volume of research and analysis on the relationship between emotional stress and physiological ailments of a wide variety. His work has demonstrated that lower back pain in particular, which afflicts more than three-quarters of all adults at one time or another, is substantially attributable to purely psychological causes (Sarno, 2007). Lower back pain alone is responsible for a tremendous amount of money, disability, and lost working hours spent on palliative relief and rehabilitation.

Even worse, Dr. Sarno (2007) has demonstrated empirically that the conclusions of other researchers (Acosta, 1990; Flannery & Flannery, 2006, & Friedman, 1990) that a large percentage of surgeries are performed for medical conditions attributable to stress rather than to any organic causes. The list of medical conditions considered highly susceptible to the influence of personality include a wide range of gastrointestinal conditions, arthritis, fibromyalgia, heart disease, high blood pressure, sciatica, and even various systemic infection and apparent local chronic injuries such as lateral epicondylitis or "tennis elbow" (Flannery & Flannery, 2006, Sarno, 2007).

In that regard, the specific mechanism identified is primarily a function of: (1) the psychological repression of negative emotions such as anger and rage, fear, anxiety, guilt, and shame; (2) the resulting displacement of that stress from the conscious mind in alternate areas where it manifests itself as physical symptoms; (3) the influence of chronically high levels specific hormones associated with the biological stress response, such as cortisol; (4) chronic overwork of the circulatory and respiratory systems; and (5)

the chronic reduction of re-oxygenation of tissues through blood flow (Sarno, 2007).

To a certain extent, susceptibility to the long-term medical consequences of stress are subject to hereditary influence. In that respect, different individuals have very different natural physiological responses to various triggers of exposure to environmental stress (Friedman, 1990). Nevertheless, many of the differences that enable some individuals to avoid the secondary consequences of unavoidable stress can be taught… [read more]

… Disease in the News: The Bird Flu

Critical Review

This critical review will examine a newspaper article published by the New York Times and entitled: 'Avian Influenza' published February 25, 2009, reviewed by Linda Vorvick, MD, a Family Physician, and Seattle Site Coordinator and Lecturer.

It was reported in the February 25, 2009 edition of The New York Times in an article entitled: 'Avian Influenza' that the avian influenza virus, also known as 'Bird Flu' historically is a virus that "infected pigs and mixed with pig influenza viruses" however "the viruses exchanged genetic information which led to the formation of a new virus." (The New York Times, 25 Feb, 2009) It was this genetic exchange that enabled the new virus to "infection humans and easily spread from person to person." (The New York Times, 25 Feb, 2009) The article relates that many of the previous flu pandemics began in this manner.


This article relates that the first avian influenza virus to infect humans "directly occurred in Hong Kong in 1997, during an avian flu epidemic on the island." (The New York Times, 25 Feb 2009) This outbreak is stated to have been "linked to chickens and classified as avian influenza A (H5N1)." (he New York Times, 25 Feb 2009)


It is related in this article that following the outbreak in Hong Kong that the bird flu virus continued to spread across the Asian continent. In October 2005, avian influenza virus was discovery in the countries of Romania and Turkey in poultry with hundreds of individuals being infected with the disease and many of them dying from the bird influenza.

This report relates that chance of the disease spreading worldwide is dependent upon the area in which the bird influenza spreads. Those who work with poultry, including farmers and individuals who travel and visit countries infected with the bird influenza are at… [read more]

94065 Spreading and Preventing the Spread of Infectious Diseases

From the European plague to the smallpox that resulted in the destruction of thousands of Native Americans, infectious diseases have been some of the worst murderers in history. Since science has learned to understand how infectious diseases are spread, however, people have been able to learn how to prevent disease from wrecking havoc on themselves and their families. A personal knowledge of how infectious diseases spread and how they can be prevented is another good to insure you are protected against them.

According to the Mayo Clinic, infectious diseases can spread from person to person through either direct or indirect contact ("Infectious Diseases" 2007). This means that while a person must come into contact with the germ that does the diseases spreading in order to get sick, that person may or may not come into contact with a sick person. Contact can be considered the first link in the chain of spreading infectious diseases. In fact, the most common type of contact is person-to-person contact, in which a person coughs on, kisses, or exchanges fluid with sick person. In addition to person-to-person contact, several other ways of spreading infectious diseases exist. Animal to person contact -- in which a sick animal or animal waste passes a bacterium or virus to a human -- and mother to unborn child contact are two other methods of direct contact. Infectious diseases can also be passed from person to person through indirect contact. An example of indirect person to person contact touching the same pencil that a person with the flu has touched. Two other types of contact, or ways infectious diseases are spread, are through the air and through vehicles such as bites and stings ("Infections Diseases" 2007). In fact the United Nations suggests that environmental changes may be releasing long buried infectious diseases into the air ("Environmental Changes" 2005). Regardless, the easiest way to prevent infectious diseases is to prevent the person-to-person contact that usually spreads those diseases.

Once a person has come into contact with an infectious disease, the second link in the chain that causes infectious diseases to spread from person to person is the germ's incubation in the body. Germs include bacteria, viruses, fungi, protozoa, and helminths, or parasites that are most commonly associated with ringworm. While… [read more]

Crohn's Disease Thesis

… Crohn's Disease: Promising New Findings About Its Molecular Basis

Like it or not, the human digestive system requires bacteria to operate. But if these friendly bacteria penetrate the wall of the intestine the bacteria can become harmful rather than helpful. "This is why a thin, continuous layer of interconnected cells, called an epithelium, lines the intestinal surface creating a barrier that prevents bacteria from crossing that border"("Researchers Identify Molecular Basis of Inflammatory Bowel Disease," 2007, European Molecular Biology). Until recently, the mechanisms that control the epithelium were unknown. Now scientists have discovered what they call "NF-kB," a signaling molecule that helps cells cope with stress by reducing inflammation in the intestinal epithelium "("Researchers Identify Molecular Basis of Inflammatory Bowel Disease," 2007, European Molecular Biology). Scientists created a mouse that does not express NEMO, a protein needed to activate NF-kB, in intestinal epithelial cells. "As a result, these mice developed severe chronic intestinal inflammation very similar to the human disease known as Crohn's" ("Researchers Identify Molecular Basis of Inflammatory Bowel Disease," 2007, European Molecular Biology).

Crohn's disease impairs the lives of more than four million people worldwide ("Researchers Identify Molecular Basis of Inflammatory Bowel Disease," 2007, European Molecular Biology). It is a chronic inflammatory disorder that can produce abdominal pain, diarrhea and weight loss. Traditional treatment therapies for Crohn's disease involve antibiotics, anti-inflammatory drugs, steroids, and surgery (Feller 2001:1). Crohn's appears to run in families. Previous research indicated that it was caused by a combination of genetic and environmental causes, the degree to which appeared uncertain. For example, two Swedish studies suggested that the risk of contracting Crohn's disease might be increased in individuals whose mothers had contracted measles during pregnancy, but subsequent research discounted the data collection involved in the studies, and found no correlation or causation in the proposed connection (Metcalf 1998:1).

The most promising research prior to the study of NB-kB research suggested that the standard treatment of first giving Crohn's patients traditional corticosteroids and then turning to newer types of anti-inflammatory drugs should be reversed. Researchers randomly assigned 65 Crohn's patients to get a combination of anti-inflammatory drugs and then steroids while a group of 64 other Crohn's patients received the conventional treatment of steroids first, followed later by the same two anti-inflammatory drugs used in the other trial. After 6 months, 60% of those who initially received infliximab and azathioprine, the anti-inflammatory drugs, were entirely free of Crohn's disease symptoms, while only 36% of those getting steroids were asymptomatic, a heartening result given the severe side effects of steroids in comparison to these other drugs (such… [read more]
