The Science of Nursing

Posted: 29 Dec 2010 10:49 PM PST

One thing is absolutely necessary for the nursing profession to survive – nursing research, emphasized Elizabeth Allen, MSN, RN, manager of accreditation services at Emerson Hospital, Concord, MA.

“When you sit down at the table with medicine, or attend a fiscal meeting, you need to be able to present in a professional manner with data that augments the points you’re trying to make. We can’t explain and substantiate our practice any other way,” she said.

So, when in 2004, Allen was asked to lead a nurse-driven initiative to enhance early nursing research efforts at Emerson, she was immediately on board. “There was a core group within nursing working on research, which is a very vital part of Magnet-designated facilities,” she explained. “We have a good beginning on the path to gain Magnet status.

“The integration of nursing research into a nursing culture is a progressive process – you just can’t make it happen overnight. You need to support those early pioneers who conduct nursing research, and let other nurses see each other succeed in investigating clinical questions,” she said.

Progressive Process

Like many other clinicians, Allen gained an appreciation for nursing research during graduate studies.

“I’ve been a nurse since 1972, after graduating from a hospital-based nursing school, and I became interested in nursing research while earning my master’s in nursing in 1999 from Regis College [Weston, MA],” she said. “I learned the value of nursing research, and became a convert during those graduate studies.”

Today, Allen co-chairs the Nursing Research Council along with Peg Bitter, RN-BC, a staff nurse recently promoted to associate nurse manager.

“We use a mentorship model, with me coaching her in how to lead a committee,” Allen noted. “We’ve been meeting monthly to create the infrastructure so the nurse at the bedside who has questions about the correct practice or policy, or who wants to challenge those practices or policies, is able to access the Cumulative Index to Nursing and Allied Health Literature (CINAHL) and other clinical reference databases on the nursing unit.”

Bitter recalled her initial introduction to nursing research at Emerson. “I was talking with one of the nurse practitioners and mentioned I had worked as a research assistant at Brigham and Women’s Hospital [Boston] when I was in nursing school,” she recalled. “Research is something I’ve always been interested in, so I went to the first meeting of the Nursing Research Council and learned they wanted a staff nurse to serve as co-chair – and I’ve been on the committee ever since.”

Solid Foundation

The shared-governance model at Emerson provided a solid foundation for involvement of nurses from all organizational levels and clinical specialties.

“If you have nurses with different educational backgrounds and practice levels on a research committee, the more seasoned ones can say to younger colleagues, ‘Let me tell you my story,’ and serve as role models to stimulate research questions,” Allen said. “Today, when someone says to me, ‘I feel like this is happening,’ I can respond, ‘How can we measure it?’ When a nurse presents an idea, I can say, ‘Sure, put together a research proposal and let’s see what it does for our patients, families and staff. To me, the nursing process and research process are one and the same.”

“It’s been a way to grow within the Emerson community,” Bitter added. “I’ve worked here more than 20 years, but it took awhile before I got involved in committees. That involvement really enriches your practice as you become engaged in something outside your own nursing unit.”

Medical librarians at Emerson have been invaluable allies in the nursing research development process. “Our past librarian Nancy Serotkin was instrumental in helping nurses from all units learn how to find answers to their questions in the professional literature, and she received our first Friends of Nursing Award,” Allen said. “Our current librarian, Melinda Marchand, met with Nancy and I to continue that culture.”

Changing the Culture

Four years ago, nurse leaders at Emerson brought in Patricia Rissmiller, DNS, PNP, RN, associate professor in the graduate program in primary healthcare nursing at Simmons College, Boston, as a facilitator and adviser to the Nursing Research Council.

“Emerson was looking for someone to be on board to get the research part of its Magnet proposal more solid and to strengthen the process of critical thinking,” Rissmiller recalled. “When I began my work with them, there were some isolated projects, but now we have more ongoing investigations, we’re participating as part of the IRB [Institutional Review Board], and we’ve increased the nursing staff’s understanding of evidence-based practice as the basis for research.”

Working with council members, Rissmiller encouraged a number of process changes to reflect research principles.

“That’s what Magnet is so clear about – it’s fine to have some research projects going, but you really need to change the nursing culture to incorporate research into practice,” she explained. “For example, all nursing policies and procedures that go through the Professional Practice Council now include citations from the professional literature to support those best practices.”

A True Inspiration

Rissmiller’s support and influence helped spark a culture change at Emerson.

“Pat [Rissmiller] is so approachable, and has an inquisitive personal style that inspires nurses to pursue clinical questions through nursing research,” Allen explained. “She makes people believe nursing research is not as daunting as we first thought when we heard the term. She distills the research process down to a manageable mental model for nurses, [see Breaking It Down] and that’s what stimulates people like Candice Kruszkowski, MSN, CPNP, RN, to tackle research questions.

“We’re hoping Candice is one of many seeds that will be planted through Pat’s influence and with the support of the Nursing Research Council,” she added.

Kruszkowski is a long-time member of the Nursing Research Committee, and credits colleagues in that group with encouraging her to go on for an advanced degree and certification as a nurse practitioner.

“Pat Rismiller is the one who got me interested in expanding my nursing role to incorporate advanced practice,” she explained. “My graduate studies helped me realize the value of nursing research, and convinced me it is possible for bedside staff to carry out meaningful research projects.”

Sandy Keefe is a frequent contributor to ADVANCE.

Breaking It Down

As an associate professor in the graduate program in primary healthcare nursing at Simmons College, Boston, Patricia Rissmiller, DNS, PNP, RN, knows very well how daunting the term “nursing research” can be to bedside clinicians.

When she was asked to serve as a consultant to the Nursing Research Council at Emerson Hospital, she emphasized the importance of breaking down the research process into manageable pieces.

“We began with seminars focused on reading and critiquing a research article, teaching nurses to ask whether the study is valid and reliable enough to justify changing their nursing practice,” she said. “That’s an important question within evidence-based practice.”

Bedside Investigators

A pediatric nurse practitioner who still engages in hands-on nursing care through a per diem position at the VNA Care Network & Hospice in Massachusetts, Rissmiller has a low-key style when involving staff nurses in research topics.

“Every day we say, ‘How come we’re doing this?’ in our heads, but typically don’t view those thoughts as research questions,” she said. “We can engage staff nurses in research by giving them the skills and tools they need – teaching them to read scholarly literature and supporting them in their inquiries.”

It’s important to empower nurses to question and investigate their own practice. “I like to point out to nurses in clinical settings, particularly at the staff nurse level, they’re right there where the action is,” Rissmiller said. “I’ll say to them, ‘You have millions of questions every day and you just need to select one to frame and explore within the context of nursing research.’”

In-hospital Research

Peg Bitter, RN-BC, an associate nurse manager at Emerson who co-chairs the Nursing Research Council, echoed that message.

“I’ve learned through my council work to view research as something I can do, rather than something in a journal that other people have done,” she explained. “I can take a small idea and turn it into a project, something I’m planning as part of the requirements for my online master’s program through University of Massachusetts at Amherst. I’m excited about doing the project and then presenting and publishing my findings with other nurses.”

Rissmiller credits Elizabeth Allen, MSN, RN, manager of accreditation services at Emerson, with following through in a way that engages nursing staff.

“Liz [Allen] is a very detail-oriented person with great follow-up, and things just get done under her leadership,” she noted. “The biggest challenge facing Emerson was getting staff nurses involved, since many had been there 30-plus years without any real involvement in nursing research.

“We encourage them to think of nursing research within the context of nursing practice, instead of something that’s done only at the doctoral level.”

Asking Questions

When Candice Kruszkowski, MSN, CPNP, RN, needed a project as part of her master’s program through Simmons College, Boston, she decided to tackle a clinical issue from her work at Emerson Hospital, Concord, MA.

“I wanted to see what I could do to improve the experience for children undergoing invasive procedures like voiding cystourethrograms (VCUGs),” she said. “The idea for medicating children during those procedures has been kicking around the unit for a period of time. Mallory Harrison, our child-life specialist, greets children on arrival and walks with them through the whole process. She heard from parents of children who weren’t medicated, telling her what a horrible experience it was and how they barely got through it.”

The VCUG studies, while essential for diagnosis and treatment, cried out for improvement.

“VCUG is really a miserable procedure; we take children who are 2-3 years old and just potty-trained, fill their bladders with contrast media, and then tell them to pee on the radiology table,” Kruszkowski explained. “It’s difficult and frightening for these young patients.”

When nurses in the same-day surgery unit began administering nasal Versed prior to VCUGs, Kruszkowski noticed a marked improvement in the youngsters’ responses. “Most of the children don’t remember a thing because of the amnesiac effect of the drug; those who do often have a positive recollection,” she said. “One child wanted to have his birthday in the radiology suite because it had been such a wonderful experience!”

Since then, the protocol has been adopted by the hospital, and is used for interventional radiology procedures, such as VCUGs, and in same-day surgery, as well. Nasal Versed has been highly effective in 99 percent of the cases, so clinicians rarely have to use any other medications or interventions to control pain or anxiety during these procedures.

By asking the right questions, Kruszkowski created a win-win situation.

“She was a graduate student with a research requirement, as well an employee at Emerson,” said Patricia Rissmiller, DNS, PNP, RN, associate professor in the graduate program in primary healthcare nursing at Simmons College. “The hospital provided her with good access to patients and great support, and in turn she provided results to share with the community about how well the hospital cares for children undergoing these procedures.”

Late-stage disease (AIDS)

Posted: 29 Dec 2010 10:45 PM PST

AIDS is usually marked by a very low number of CD4+ lymphocytes, followed by a rise in the frequency of opportunistic infections and cancers. Doctors monitor the number and proportion of CD4+ lymphocytes in the patient’s blood in order to assess the progression of the disease and the effectiveness of different medications. About 10% of infected individuals never progress to this overt stage of the disease and are referred to as nonprogressors.

OPPORTUNISTIC INFECTIONS. Once the patient’s CD4+ lymphocyte count falls below 200 cells/mm3, he or she is at risk for a variety of opportunistic infections. The infectious organisms may include the following:

* Fungi. The most common fungal disease associated with AIDS is Pneumocystis carinii pneumonia (PCP). PCP is the immediate cause of death in 15-20% of AIDS patients. It is an important measure of a patient’s prognosis. Other fungal infections include a yeast infection of the mouth (candidiasis or thrush) and cryptococcal meningitis.
* Protozoa. Toxoplasmosis is a common opportunistic infection in AIDS patients that is caused by a protozoan. Other diseases in this category include isoporiasis and cryptosporidiosis.
* Mycobacteria. AIDS patients may develop tuberculosis or MAC infections. MAC infections are caused by Mycobacterium avium-intracellulare, and occur in about 40% of AIDS patients. It is rare until CD4+ counts falls below 50 cells/mm3.
* Bacteria. AIDS patients are likely to develop bacterial infections of the skin and digestive tract.
* Viruses. AIDS patients are highly vulnerable to cytomegalovirus (CMV), herpes simplex virus (HSV), varicella zoster virus (VZV), and Epstein-Barr virus (EBV) infections. Another virus, JC virus, causes progressive destruction of brain tissue in the brain stem, cerebrum, and cerebellum (multifocal leukoencephalopathy or PML), which is regarded as an AIDS-defining illness by the Centers for Disease Control and Prevention.

AIDS DEMENTIA COMPLEX AND NEUROLOGIC COMPLICATIONS. AIDS dementia complex is usually a late complication of the disease. It is unclear whether it is caused by the direct effects of the virus on the brain or by intermediate causes. AIDS dementia complex is marked by loss of reasoning ability, loss of memory, inability to concentrate, apathy and loss of initiative, and unsteadiness or weakness in walking. Some patients also develop seizures. There are no specific treatments for AIDS dementia complex.

MUSCULOSKELETAL COMPLICATIONS. Patients in late-stage AIDS may develop inflammations of the muscles, particularly in the hip area, and may have arthritislike pains in the joints.

ORAL SYMPTOMS. In addition to thrush and painful ulcers in the mouth, patients may develop a condition called hairy leukoplakia of the tongue. This condition is also regarded by the CDC as an indicator of AIDS. Hairy leukoplakia is a white area of diseased tissue on the tongue that may be flat or slightly raised. It is caused by the Epstein-Barr virus.

AIDS-RELATED CANCERS. Patients with late-stage AIDS may develop Kaposi’s sarcoma (KS), a skin tumor that primarily affects homosexual men. KS is the most common AIDS-related malignancy. It is characterized by reddish-purple blotches or patches (brownish in African-Americans) on the skin or in the mouth. About 40% of patients with KS develop symptoms in the digestive tract or lungs. KS may be caused by a herpes viruslike sexually transmitted disease agent rather than HIV.

The second most common form of cancer in AIDS patients is a tumor of the lymphatic system (lymphoma). AIDS-related lymphomas often affect the central nervous system and develop very aggressively.

Invasive cancer of the cervix (related to certain types of human papilloma virus [HPV]) is an important diagnostic marker of AIDS in women.

Acute retroviral syndrome

Posted: 29 Dec 2010 09:42 PM PST

Acute retroviral syndrome is a term used to describe a group of symptoms that can resemble mononucleosis and that may be the first sign of HIV infection in 50-70% of all patients and 45-90% of women. Most patients are not recognized as infected during this phase and may not seek medical attention. The symptoms may include fever, fatigue, muscle aches, loss of appetite, digestive disturbances, weight loss, skin rashes, headache, and chronically swollen lymph nodes (lymphadenopathy). Approximately 25-33% of patients will experience a form of meningitis during this phase in which the membranes that cover the brain and spinal cord become inflamed. Acute retroviral syndrome develops between one and six weeks after infection and lasts for two to three weeks. Blood tests during this period will indicate the presence of virus (viremia) and the appearance of the viral p24 antigen in the blood.
Latency period

After the HIV virus enters a patient’s lymph nodes during the acute retroviral syndrome stage, the disease becomes latent for as many as 10 years or more before symptoms of advanced disease develop. During latency, the virus continues to replicate in the lymph nodes, where it may cause one or more of the following conditions:

PERSISTENT GENERALIZED LYMPHADENOPATHY (PGL). Persistent generalized lymphadenopathy, or PGL, is a condition in which HIV continues to produce chronic painless swellings in the lymph nodes during the latency period. The lymph nodes that are most frequently affected by PGL are those in the areas of the neck, jaw, groin, and armpits. PGL affects between 50-70% of patients during latency.

CONSTITUTIONAL SYMPTOMS. Many patients will develop low-grade fevers, chronic fatigue, and general weakness. HIV may also cause a combination of food malabsorption, loss of appetite, and increased metabolism that contribute to the so-called AIDS wasting or wasting syndrome.

OTHER ORGAN SYSTEMS. At any time during the course of HIV infection, patients may suffer from a yeast infection in the mouth called thrush, open sores or ulcers, or other infections of the mouth; diarrhea and other gastrointestinal symptoms that cause malnutrition and weight loss; diseases of the lungs and kidneys; and degeneration of the nerve fibers in the arms and legs. HIV infection of the nervous system leads to general loss of strength, loss of reflexes, and feelings of numbness or burning sensations in the feet or lower legs.

AIDS in children

Posted: 29 Dec 2010 08:39 PM PST

Since AIDS can be transmitted from an infected mother to the child during pregnancy, during the birth process, or through breast milk, all infants born to HIV-positive mothers are a high-risk group. As of 2000, it was estimated that 87% of HIV-positive women are of childbearing age; 41% of them are drug abusers. Between 15-30% of children born to HIV-positive women will be infected with the virus.

AIDS is one of the 10 leading causes of death in children between one and four years of age. The interval between exposure to HIV and the development of AIDS is shorter in children than in adults. Infants infected with HIV have a 20-30% chance of developing AIDS within a year and dying before age three. In the remainder, AIDS progresses more slowly; the average child patient survives to seven years of age. Some survive into early adolescence.
Causes and symptoms

Because HIV destroys immune system cells, AIDS is a disease that can affect any of the body’s major organ systems. HIV attacks the body through three disease processes: immunodeficiency, autoimmunity, and nervous system dysfunction.

Immunodeficiency describes the condition in which the body’s immune response is damaged, weakened, or is not functioning properly. In AIDS, immunodeficiency results from the way that the virus binds to a protein called CD4, which is primarily found on the surface of certain subtypes of white blood cells called helper T cells or CD4 cells. After the virus has attached to the CD4 receptor, the virus-CD4 complex refolds to uncover another receptor called a chemokine receptor that helps to mediate entry of the virus into the cell. One chemokine receptor in particular, CCR5, has gotten recent attention after studies showed that defects in its structure (caused by genetic mutations) cause the progression of AIDS to be prevented or slowed. Scientists hope that this discovery will lead to the development of drugs that trigger an artificial mutation of the CCR5 gene or target the CCR5 receptor.

Once HIV has entered the cell, it can replicate intracellularly and kill the cell in ways that are still not completely understood. In addition to killing some lymphocytes directly, the AIDS virus disrupts the functioning of the remaining CD4 cells. Because the immune system cells are destroyed, many different types of infections and cancers that take advantage of a person’s weakened immune system (opportunistic) can develop.

Autoimmunity is a condition in which the body’s immune system produces antibodies that work against its own cells. Antibodies are specific proteins produced in response to exposure to a specific, usually foreign, protein or particle called an antigen. In this case, the body produces antibodies that bind to blood platelets that are necessary for proper blood clotting and tissue repair. Once bound, the antibodies mark the platelets for removal from the body, and they are filtered out by the spleen. Some AIDS patients develop a disorder, called immune-related thrombocytopenia purpura (ITP), in which the number of blood platelets drops to abnormally low levels.

As of 2000, researchers do not know precisely how HIV attacks the nervous system since the virus can cause damage without infecting nerve cells directly. One theory is that, once infected with HIV, one type of immune system cell, called a macrophage, begins to release a toxin that harms the nervous system.

The course of AIDS generally progresses through three stages, although not all patients will follow this progression precisely:

Alpha-carotene & cancer

Posted: 28 Dec 2010 09:53 PM PST

Call it the beta-carotene quandary. Researchers are scrambling to figure out why foods rich in beta-carotene seem to reduce the risk of lung cancer while high doses of beta-carotene supplements seem to increase the risk.

One theory–that massive doses of beta-carotene keep people from absorbing other substances in fruits and vegetables that may be the real protectors–now has new support from a study from the National Cancer Institute in Bethesda, Maryland.

Regina Ziegler and co-workers analyzed the diets that 763 men recalled eating before they were diagnosed with lung cancer. She compared the diets to those of 564 similar men with no cancer.

The results: Lung cancer was more closely associated with a low intake of alpha-carotene than with a low intake of beta-carotene. Among the men who were current or recent smokers, a diet poor in beta-carotene increased the risk of lung cancer by 60 percent, while a diet poor in alpha-carotene roughly doubled the risk.

Alpha- and beta-carotene usually occur in the same foods. Only seven of the men had frequently eaten foods that are especially rich in beta-carotene (like spinach and other leafy greens) and had infrequently eaten foods that are rich in both carotenes (like carrots and sweet potatoes). All seven got lung cancer.

“It is premature to conclude that alpha-carotene is protective in humans,” says Ziegler. “The most rational way to reduce lung cancer risk is to eat a variety of vegetables and fruits and, most important, to not smoke.”

Aids Risk factors

Posted: 28 Dec 2010 08:23 PM PST

AIDS can be transmitted in several ways. The risk factors for HIV transmission vary according to category:

* Sexual contact. Persons at greatest risk are those who do not practice safe sex, those who are not monogamous, those who participate in anal intercourse, and those who have sex with a partner with symptoms of advanced HIV infection and/or other sexually transmitted diseases (STDs). In the United States and Europe, most cases of sexually transmitted HIV infection have resulted from homosexual contact, whereas in Africa, the disease is spread primarily through sexual intercourse among heterosexuals.
* Transmission in pregnancy. High-risk mothers include women married to bisexual men or men who have an abnormal blood condition called hemophilia and require blood transfusions, intravenous drug users, and women living in neighborhoods with a high rate of HIV infection among heterosexuals. The chances of transmitting the disease to the child are higher in women in advanced stages of the disease. Breast feeding increases the risk of transmission by 10-20%. The use of zidovudine (AZT) during pregnancy, however, can decrease the risk of transmission to the baby.
* Exposure to contaminated blood or blood products. With the introduction of blood product screening in the mid-1980s, the incidence of HIV transmission in blood transfusions has dropped to one in every 100,000 transfused. With respect to HIV transmission among drug abusers, risk increases with the duration of using injections, the frequency of needle sharing, the number of persons who share a needle, and the number of AIDS cases in the local population.
* Needle sticks among health care professionals. Present studies indicate that the risk of HIV transmission by a needle stick is about one in 250. This rate can be decreased if the injured worker is given AZT, an anti-retroviral medication, in combination with other medication.

HIV is not transmitted by handshakes or other casual non-sexual contact, coughing or sneezing, or by blood-sucking insects such as mosquitoes.
AIDS in women

AIDS in women is a serious public health concern. Women exposed to HIV infection through heterosexual contact are the most rapidly growing risk group in the United States population. The percentage of AIDS cases diagnosed in women has risen from 7% in 1985 to 23% in 1999. Women diagnosed with AIDS may not live as long as men, although the reasons for this finding are unclear.

Five Steps to Effective Infection Control in Long Term Care

Posted: 28 Dec 2010 03:01 AM PST

Effective Infection Control in Long Term Care

Probably no other category of illness has such major implications or unpredictability of outcome for a health care provider than infection and septic shock. A “simple” urinary tract infection can evolve into urosepsis and a resource intensive course of therapy in critical care. Urosepsis alone is the major cause of death of adults over 65.

It is for this reason that prevention of this complication must be one of the health care provider’s highest priorities. Being vigilant to preventive measures is imperative. Something as simple as handwashing is critical to the spread of infection. But so often, this simple approach is neglected.

As the health care provider tracks and trends lengths of stay and tries to identify variances which result in a longer stay than anticipated, infection should always be considered. When looking at infections, it is important to differentiate between community acquired and nosocomial infections. For example, when looking at pneumonia in a subacute setting, it is important to differentiate between an increase in pneumonia in the general population during the flu season, and infections which may be acquired in the facility due to care related issues.

The way to differentiate the two is line listing of infections. For each patient with an infection, list the site of infection, the organism, sensitivity report, date of admission and date of symptoms onset. Then categorize together all of the patients with the same site and organisms, then drop off the infections which occurred within 48 hours of admission (not enough time for incubation of a nosocomial infection). Then take the patients with the same site and organism and look at the sensitivity reports. If the sensitivity to antibiotics is variable, it is unlikely that the infections came from a single source. If on the other hand, the sensitivities are identical, it is unlikely that they were randomly acquired community infections.

Once sepsis occurs, aggressive monitoring, antibiotic therapy, and fluid management are critical for successful outcome. In some cases, the timely diagnosis of infection initiation of antibiotic therapy can make the difference between life and death. Ineffective management can result in extended periods of illness. Cost issues regarding antibiotic therapy can be complicated. A tradition step approach to antibiotics, starting with standard and less expensive ones and then advancing to newer, more expensive ones if they don't work may seem cost effective. But if going to the newer “big guns” earlier may result in shorter period of illness and need for critical care. On the other hand, if you jump to the “Big Guns” and they don’t work, where do you go next?

These steps should be followed in the continuing care setting to ensure that infections are controlled:

1.

Monitor new admissions as well as existing patients for evidence of infections; if an infection is identified, determine if it is community acquired (prior to admission to your program) or nosocomial
2.

Begin a line listing of each infection so it can be tracked from start to finish, including the organism causing the infection, the sensitivity report, the treatment used, and the date of resolution
3.

Identify patterns of infections that may indicate they may be spread by the facility or staff; such patterns may include several patients on a unit having the same source organism with the same antibiotic sensitivity report indicating they shared the same source, or a geographical distribution pattern of an infection that may indicate the spread by poor hand-washing
4.

Follow state and local health department requirements regarding reporting of infections.
5.

Educate staff with information gained through above steps as to how they can prevent the spread of infections in your particular setting

Following these steps will help ensure that your patients and staff are protected from unnecessary infections, and that you will enjoy higher success with your clinical outcomes.

What is Prognosis?

Posted: 28 Dec 2010 02:52 AM PST

Mean of Prognosis

Prognosis is derived from Ancient Greek and can translate to foreseeing or foreknowledge.

It can sometimes get confused with the word diagnosis, which means to give name to a person's health condition or decide what ailments they suffer from.

When a doctor gives a prognosis, they are typically using the best resources they have like clinical studies and previous experiences treating a disease to tell a patient what they can expect from an illness and the likelihood that they will survive the illness.

A prognosis can help patients determine the types of care they should undertake to treat various illnesses.

A prognosis isn't based solely on empirical scientific data. It's really the doctor's best guess, which may be guided in part by how other people have responded to the same illness. When a disease is rare or not frequently studied, determining survivability or outcome isn't always possible. With fatal diseases, doctors may give ranges of possible dates by which they expect a patient not to be living, and there is some concern about prognoses when diseases might be but aren't always fatal. If attitude makes a difference in recovery, you don't want patients assuming they can't survive a dangerous disease.

When a person receives a prognosis, it's wise to remember that this is a best guess based on the previous experience or knowledge of the doctor. Like many prediction methods, it has an element of chance and doesn't fully take into account the way any one person will respond to disease. On the other hand, certain common diseases, especially those that prove fatal may not be subject to that much guessing about eventual outcome.

Doctors do use some scientific tools to predict likelihood of death in people who are critically ill. One scale, the APACHE II scale, is fairly effective in predicting mortality, especially within a week of expected death. This scale may be used as a prognostic device to determine types of treatment that should be given or withheld, and to help inform family that death is likely or imminent.
Even with minor illnesses, a prognosis can prove helpful. A patient with strep throat may be told that their symptoms should resolve in a few days after starting antibiotic treatment. If symptoms persist beyond the point when the doctor predicted the patient would get better, this may indicate that different treatment is needed. When you receive small prognoses like these for small illnesses, it's a good idea to understand when you expect to get better. This way, you can contact your doctor if treatment doesn't appear to be working.

What is Acne

Posted: 24 Dec 2010 07:09 AM PST

Acne is an inflammatory disease of the skin. It is a disorder of the skin's pilosebaceous unit, which consists of an oil gland (sebaceous gland) and a canal (pore) that contains a hair called a follicle. The pore becomes blocked and causes lesions commonly known as pimples.
Who gets it?

Acne affects young people as well as adults. It can occur at anytime during the lifespan including the newborn period, but it is not until puberty that it becomes a common problem. In general, the condition is a bit more common in males than in females and is usually more severe in males than in females. It is also more common in Caucasions.
What causes it?

The actual cause of acne is unknown. One important factor does seem to be rising levels of the hormones called androgens (male sex hormones) that are found in both boys and girls at the time of puberty. Another factor is heredity or genetics. Acne does seem to run in families. Girls or women may find their acne flares 2 to 7 days before the onset of their menstrual period. Pregnancy, coming on or off birth control pills, and stress can make acne worse. Certain drugs (androgens, lithium, and barbiturates) can cause acne. Physical trauma (squeezing, picking, rubbing, hard scrubbing or pressure from helmets, tight collars, or backpacks), greasy cosmetics, and high humidity can make acne worse.
What are the symptoms?

Acne lesions usually occur on the face, neck, back, shoulders and chest. The basic lesion in acne is called a comedo and is an enlarged hair follicle plugged with oil and bacteria. When the comedo stays below the skin it is called a whitehead. When it reaches the surface of the skin and opens up it is called a blackhead. Papules (small inflamed lesions that look like pink bumps on the skin), pustules (pimples), nodules (large, sore, solid lesions deep in the skin) and cysts (deep, inflamed, pus-filled lesions) are other types of acne lesions. Cysts can cause serious scaring and deformity.
How is it diagnosed?

Diagnosis is primarily based on the appearance of the skin. No testing is usually required.
What is the treatment?

Treatment is designed to prevent formation of new lesions and aid the healing of old lesions. Treatment may consist of topical creams or gels, with or without oral medications, depending on the severity of the acne. At a follow-up visit, a skin specialist called a dermatologist would re-evaluate the patient’s acne, get feedback concerning the treatment, and make any necessary adjustments in the treatment plan. Topical medications that can normalize the shedding of skin cells may contain benzoyl peroxide, sulfur, resorcinol, salicylic acid or tretinoin, or retinoic acid. Oral antibiotics (such as tetracycline, doxycycline, minocycline, or erythromycin) may be prescribed if there are numerous inflammatory lesions. Topical antibiotics (applied to a localized area of the skin), such as clindamycin or erythromycin, are also for milder forms of inflammatory acne. Oral tetracyclines are usually not prescribed for children until after they have all their permanent teeth, because it can permanently discolor teeth that are still forming. Severe acne may benefit from a synthetic vitamin A analogue. However, this treatment requires careful consideration of potential side effects. Surgical intervention may include professional chemical skin peeling, removal of eruptions or scars through dermabrasion, or removal and/or drainage of cysts.
Self-care tips

If you have acne, clean your skin gently but thoroughly with soap and water, removing all dirt or make-up. Wash as often as needed to control oil, at least daily and after exercising. Use a clean washcloth every day to prevent bacterial infection. Shampoo hair daily when possible, using a dandruff shampoo if necessary. Comb or pull hair back to keep hair out of the face. Don’t squeeze, scratch, pick, or rub lesions because these activities can increase skin damage. Don’t rest your face on your hands. This irritates the skin of the face. Unlike other conditions, acne treatment usually requires 6 to 8 weeks before improvement is noted. Be patient!

Aicardi Syndrome

Posted: 24 Dec 2010 06:46 AM PST

Aicardi syndrome is a rare disorder that was first identified in 1965 by a French neurologist named Dr. Jean Aicardi. Children with this disorder are either partially or completely missing the nerve fibers, called the corpus callosum, that link the two hemispheres of the brain. This symptom is usually accompanied by infantile spasms (seizures), mental retardation, and growths, called lacunae, on the retina or optic nerve.
Who gets it?

Aicardi syndrome affects only females. Researchers have identified only between 300 and 500 cases of Aicardi syndrome worldwide.
What causes it?

The exact cause of Aicardi syndrome is not currently known. However, researchers believe it is an X-linked genetic disorder that occurs because of a random, unpredictable mutation. In simple terms, chromosomes are thread-like structures that carry genes and help to pass on genetic information. When a gene mutates, it undergoes a sudden structural change that results in a new characteristic or trait not originally found in the parent gene. The X chromosome is one of two chromosomes that determine an individual’s sex. Males have an X and a Y chromosome, while females have two X chromosomes. Defects that are X-linked appear on the X chromosome only, and not the Y. Researchers have connected Aicardi syndrome to the X chromosome because it occurs only in females. It is not a hereditary condition.
What are the symptoms?

Infants with Aicardi syndrome may have an apparently normal birth, but begin to develop symptoms between the ages of 3 and 5 months. At this age, important stages in normal brain development cannot occur because of the missing or incomplete corpus callosum that allows the right side of the brain to communicate with the left. Because of this, the infant begins to have infantile spasms, which is a type of seizure. Other symptoms that are definite hallmarks of Aicardi syndrome include mental retardation and growths, called lacunae, on the retina of the eye. Retinal lacunae can cause blindness. Other types of brain defects, such as microcephaly (small brain), porencephalic cysts (cerebrospinal fluid-filled cavities or gaps in the brain where there should be healthy brain tissue), and enlarged ventricles, may also be present.
How is it diagnosed?

Females are diagnosed with Aicardi syndrome, usually between the ages of three months and five months, when infantile spasms alert the parents and healthcare provider to a disorder. A computed tomography (CT) scan or magnetic resonance imaging (MRI) of the head will show any abnormalities with the corpus callosum, cysts, or enlarged ventricles. The doctor may also order an electroencephalogram (EEG), which measures the electrical activity in the brain and helps to identify types of seizures. An eye exam will reveal any growths on the retina. The combination of female sex, seizures, abnormalities with the corpus callosum, and retinal lacunae provide a definite diagnosis of Aicardi syndrome. In some cases, the corpus callosum may look normal, but other abnormal formations in the brain are present.
What is the treatment?

There is no cure or standard treatment for Aicardi syndrome. Treatment is specific to the symptoms, and usually involves medication to manage seizures and early intervention programs for developmental delays.
Self-care tips

While the prognosis for Aicardi syndrome does not appear good, continuing genetic research aims to find the cause of and a treatment for this disorder. If your child has Aicardi syndrome, you may find it helpful to seek the support of the Aicardi Syndrome Foundation, which can keep you up-to-date on the most recent findings.

Mental Retardation

Posted: 24 Dec 2010 06:41 AM PST

Mental retardation is a developmental disability that can appear from birth through the age of 18. People who are mentally retarded function at an intellectual level that is below average and have difficulties with learning and daily living skills.
Who gets it?

Approximately 2.5 to 3% of the total population are mentally retarded. In most cases, it is a lifelong condition. There is no connection between mental retardation and gender or race.
What causes it?

In many cases, the cause of mental retardation is not found. About 5% of all cases can be linked to heredity. In these instances, the cause is a genetic defect, such as an inherited abnormal gene, gene mutation, or chromosomal defect. In very simple terms, genes are carried on thread-like structures called chromosomes, and determine our individual characteristics, such as how we look. Just one missing or faulty gene or chromosome can cause a birth defect. Two of the most common inherited causes of mental retardation are fragile X syndrome, caused by a defect in the chromosome that determines sex, and Down syndrome, caused by an extra chromosome. Gene defects such as phenylketonuria (PKU) can cause mental retardation if not found and treated early, as can hypothyroidism. Mental retardation can also occur as a result of the mother’s behaviors or illnesses during pregnancy. Behaviors that can affect the fetus’ developing brain include poor nutrition, excessive alcohol consumption, drug abuse, and cigarette smoking during pregnancy. Mental retardation due to alcohol abuse is called fetal alcohol syndrome. Pregnant women who have infections or illnesses such as rubella (German measles), cytomegalovirus, toxoplasmosis, glandular disorders, high blood pressure, or blood poisoning, or who are exposed to radiation during pregnancy, may have a mentally retarded child.

Some birth defects that affect the head, brain, and central nervous system have mental retardation as a symptom. For example, neural tube defects, where the neural tube that forms the spinal cord does not close completely, can cause cerebrospinal fluid to accumulate on the brain. The pressure causes hydrocephalus, a cause of mental retardation. Difficulties in the birth process can also result in mental retardation. These include premature birth, head injury during birth, or lack of oxygen. Children can be born with normal intelligence but develop mental retardation because of childhood illnesses or injuries. Illnesses that cause mental retardation if not properly treated include chickenpox, measles, whooping cough, hyperthyroidism, or a bacterial infection called Hib disease. Meningitis and encephalitis can cause swelling in the brain that causes brain damage and mental retardation. Children who suffer a traumatic brain injury either accidentally or through abuse that includes violent blows to or shaking of the head may suffer brain damage and mental retardation.

Environmental factors that affect mental development include emotional and physical neglect. Daily stimulation is essential to a child’s mental development. Infants who are neglected, as well as those who do not receive adequate nutrition, may suffer irreversible mental setbacks. Small children who live in older apartment buildings and homes painted with lead-based paint are at risk for developing lead poisoning if they put flakes of this paint into their mouths. Lead exposure can also cause mental retardation.
What are the symptoms?

The severity of symptoms of mental retardation and when they appear depend upon the cause. Symptoms appear during infancy if the condition is caused by a genetic disorder or an event during the pregnancy or birth process. A childhood illness or injury that causes a brain injury may suddenly make once easy tasks difficult for the child, and cause learning difficulties. In general, children who are mentally retarded fall behind when it comes to reaching developmental milestones. They may also show signs of aggression and self-injury. As they get older their scores on standardized intelligent quotient (IQ) tests are low and they have difficulties with daily life skills, called adaptive skills. Adaptive skills include basic communication, self-care, social, safety, and work skills. IQ levels are generally used to classify degrees of mental retardation. Children with mild retardation score in the range of 50 to 75. These children may not be diagnosed until they enter school because they develop social and communication skills during their first five years. However, learning difficulties become evident in a formal school setting. These children can learn up to the 6th grade level and can live independently with the support of family, community, and social services. Most children who are mentally retarded are in the mild category. About 10% of those with mental retardation are considered moderately retarded, with IQ scores in the range of 35 to 55. During early childhood, these children are able to learn to talk and communicate, but have poor social skills and awareness. Academically, they have difficulty working past the 2nd grade level. With supervision, they can learn some skills and take care of their personal needs. As these children reach adulthood, they can work well in a supervised setting, such as a group home. Children are classified as severely retarded when their IQ scores fall in the range of 20 to 40. This group accounts for only 3 to 4% of the mentally retarded population. The severely retarded have poor muscle coordination and limited communication and self-care skills during early childhood. By school age, they can learn some basic self-care and communication skills. These children benefit from living in a group home as they reach adulthood, and can perform some self-care under complete supervision.

Profound retardation accounts for 1 to 2% of all mentally retarded people. With IQ scores of 20 to 25, these children have little muscle coordination during early childhood and do not reach developmental milestones, such as walking and talking. As they grow older, they may be able to perform some of the most basic self-care skills and may develop some speech skills. However, the profoundly retarded require skilled nursing care and constant supervision. Studies have shown that those with severe to profound mental retardation have a shortened life expectancy due to diseases that are often associated with these degrees of retardation. The American Association on Mental Retardation (AAMR) classifies degrees of mental retardation by the level of support the individual needs. These are intermittent support, limited support, extensive support, and pervasive (constant) support.
How is it diagnosed?

Early diagnosis of mental retardation is important for developing an individualized plan for learning and life skills. If your doctor suspects mental retardation, he or she will take a complete medical history and perform a physical examination to determine symptoms and their possible cause. You may also need to see a child neurologist or neuropsychologist, who specializes in disorders of the nervous system. If your child is old enough, he or she may be given a standardized test of intelligence (IQ test). Commonly used tests include the Stanford-Binet Intelligence Scale, the Wechsler Intelligence Scales, the Wechsler Preschool and Primary Scale of Intelligence, and the Kaufmann Assessment Battery for Children. Physicians generally use the Bayley Scales of Infant Development to assess developmental skills in younger children. The Woodcock-Johnson Scales of IndependentBehavior and the Vineland Adaptive Behavior Scale (VABS) may also be used. Your doctor will make a diagnosis of mental retardation if your child has below average intellectual skills (an IQ below 70 – 75) and is limited in two or more adaptive skill (life skills) areas. During the 16th to 20th weeks of pregnancy, a small amount of amniotic fluid can be withdrawn from the mother’s womb and tested for a number of genetic defects. This test is called amniocentesis. A low level of alpha-fetoprotein in the amniotic fluid or in the mother’s blood during pregnancy can indicate Down syndrome in the fetus.
What is the treatment?

Treatment of mental retardation involves developing an individualized plan based upon the child’s skills and needs. Early intervention programs are available in many areas to assess the needs of mentally retarded children under the age of three and provide treatment. The federal government mandates that all children between the ages of 3 and 21 who are mentally retarded receive testing and individualized education and skills training, as appropriate, within the public school system at no charge to the child’s family. The severity of retardation determines how far the child can go within the school system. The most important component of any treatment program is the love and support of the family. Most families with a mentally retarded child benefit from family therapy and support groups that help the family cope with the day-to-day demands of raising a child with special needs. Older mentally retarded children benefit from occupational therapy to help them develop life skills that will aid them in functioning independently or semi-independently as adults. While there are exceptions, most mentally retarded children will thrive in a loving home environment, rather than a residential facility. All newborns should be screened for phenylketonuria (PKU) and hyperthyroidism. Immediate treatment of these disorders can prevent retardation.
Self-care tips

If you are pregnant, you can help prevent mental retardation in your unborn child by getting good prenatal care, avoiding alcohol and cigarette smoking, following a healthy diet that is rich in green leafy vegetables, and taking prenatal vitamins, as recommended by your healthcare provider. Having your child immunized against diseases such as measles and Hib can also prevent the types of illnesses that can cause mental retardation. If you have mentally retarded child, seek the support of family and community. Your healthcare provider can put you in touch with a local agency that can help provide you with the resources you need to keep your family strong.
