Prosopagnosia - Face Blindness


Prosopagnosia, sometimes called face blindness, may be present from childhood

This is a pretty rare disorder,Individuals with this type often do not realize until they are older that they are unable to recognize faces as well as other people do. A recent study conducted in Germany surveyed the face recognition abilities of a large group of students, and reported a prevalence rate of 2-2.5%. That is, as many as one in 50 people may suffer from developmental prosopagnosia. If this figure is correct, there may be 1.5 million prosopagnosics in the UK alone.

Prosopagnosia

Prosopagnosia is thought to be the result of abnormalities, damage, or impairment in the right fusiform gyrus, a fold in the brain that appears to coordinate the neural systems that control facial perception and memory but It’s not a memory problem. Acquired prosopagnosia may occur after brain damage from head injury, stroke, or neurodegenerative diseases. Individuals with this type had normal face recognition abilities in the past, but this has been impaired or lost due to brain injury.


It would be pretty easy to figure out if you have this problem without taking a test. It causes some pretty bizarre situations where you keep treating people you know like they are strangers because you don't recognize them.Many people occasionally fail to recognise a familiar face, or even mistake an unknown person for someone they know. However, individuals with prosopagnosia have a severe face recognition deficit, affecting even the most familiar faces, such as their spouse or children.

Prosopagnosia

Individuals with prosopagnosia must learn other ways of remembering faces. Clues such as hair, voice, and clothes may help identify people. Some prosopagnosics have reported avoidance of social interactions, problems with interpersonal relationships, damage to career, and even depression. In extreme cases, prosopagnosics may develop social anxiety disorder, characterized by fear and avoidance of social situations that may cause embarrassment. Many individuals with the disorder report difficulty watching movies and television shows since they cannot identify the characters from one scene in the next. Researchers are working on ways to help individuals with prosopagnosia improve their face recognition.


There is no formal treatment for prosopagnosia. However, many researchers are now working in this area, and you may be able to take part in a study investigating prosopagnosia. Some research focuses on advancing our understanding of the causes and basis of prosopagnosia, whereas other investigators are examining the effectiveness of training programmes designed to improve face recognition.

Bird Flu Symptoms in Humans

Bird flu (avian influenza) is a disease caused by an influenza virus that primarily affects birds. In the late 1990s, a new strain of bird flu arose that was remarkable for its ability to cause severe disease and death, especially in domesticated birds such as ducks, chickens, or turkeys. As a result, this strain was called highly pathogenic (meaning very severe and contagious) avian influenza and termed H5N1. A new strain of bird flu has been identified in China. The influenza A virus is termed H7N9 (H7N9 Chinese bird flu). The identification of the virus was reported Mar. 31, 2013; the new strain is different from the H5N1 bird flu virus.
Bird Flu Symptoms in Humans



What are the symptoms of bird flu in humans? Sometimes it starts like ordinary flu, with a bit of a cold, but that isn't absolutely invariable, some people start off with a cough, coughing from bird flu symptoms can be dry (wheezing cough that brings up no mucus) or productive (coughing that brings up and expels infected mucus) and can last for weeks after exposure. This is typical of most influenza infections but should be examined nonetheless and then become short of breath and develop muscle aches, unexplained muscle aches over the body are a serious symptom and should prompt an examination if experienced in conjunction with fever, nausea, diarrhea and headache. So getting a fever is a very important feature, if you haven't got a thermometer, you should get one and be able to measure your temperature and be able to note if it goes up to 38 degrees. If it's not you don't need to worry about it, it's probably a flu-like illness which is very common and which isn't necessarily due to bird flu.

Less severe symptoms can also include eye infections (conjunctivitis).
More serious symptoms of bird flu include Pneumonia, Acute respiratory distress, Viral pneumonia and other severe and life-threatening complications.

-->
So, What should you do if you have reason to suspect you're infected? You need to get to a medical facility that can look after you in terms of providing artificial ventilation if that's necessary, and one that can administer antiviral drugs, particularly in the early stages of the disease before the body goes into this cytokine storm phase; because it's only in that early phase that the antivirals are going to do anything. The treatment otherwise is supportive and to overcome any organ problems like lung failure and kidney failure from the virus spreading into those different parts of the system.

Achilles Tendon Injuries - Causes and Treatment

Causes of Achilles Tendon Injury

  • The biggest contributing factor is ignoring the pain in the tendon.
  • Achilles pain commonly occurs from shearing and stretching forces placed on the Achilles tendon.
  • Excess pronation (rolling over of the foot) causes extra strain on the tendon. Inflammation of the tendon is a common result along with tightening of the calf muscles. Since the calf muscles are connected to the Achilles tendon, the Achilles turns out to be the 'weakest link' in the chain. The Achilles tendon ends up being overstretched, resulting in irritation and inflammation. 
  • Sudden increases in training can lead to Achilles tendonitis.
Achilles Tendon Injuries

  • Excessive hill running or speed work.
  • Inappropriate shoes. If the soles of the shoes are too stiff, this causes the forefoot to have limited movement. This can lead to increased tension to the Achilles tendon.
  • Studies have shown that excessive heel cushioning can be a contributing factor. Air filled heels are not very good for Achilles tendonitis.
  • Tight calf muscles.
  • Women who take up running are at a greater risk. This mainly affects women who wear high-heeled shoes, which effectively shortens the Achilles tendon. When the individual then takes up running in "flat shoes", the Achilles tendon is put under increased tension.


Preventing Achilles Tendon Injury
The best way to prevent an Achilles tendon injury is to a) stay in overall good shape, and b) warm-up, stretch, and strengthen the Achilles tendons. The best way to prevent an Achilles tendon injury from getting worse is to address the injury immediately: it will get worse if not addressed. For more information on preventing Achilles tendon injuries see: Preventing Achilles Tendon Injury.

Treatment of Achilles Tendonitis
Treatment of Achilles tendonitis begins with resting the tendon to allow the inflammation to settle down. In more serious situations, adequate rest may require crutches or immobilization of the ankle. Learn more about different treatments for Achilles tendonitis, including ice, medications, injections, and surgery.

What is Herpes Simplex?

Herpes simplex is an infectious viral inflammatory type, which is characterized by the appearance of skin lesions consist of small vesicles grouped in clusters and surrounded by a red halo. It is caused by the herpes simplex virus, or herpes virus hominis, type I (HSV-1) affecting face, lips, mouth and upper body, and type II (HSV-2) that occurs most frequently in genital and bottom of body.2 currently no cure for the herpes.3

However there are several forms of treatment available to reduce symptoms and speed the healing process of injuries, after which the virus persists in a latent form body until the next episode activo.4 recurrence of herpes simplex types to be distinguished from herpes zoster is an entirely different disease entity.


Symptoms
Herpes symptoms can vary. Many infected individuals have few, if any, noticeable symptoms. In people who do have symptoms, the symptoms start 2 to 20 days after the person was exposed to someone with HSV infection. Symptoms may last for several weeks.
Herpes Simplex

The first episode of herpes is usually worse than outbreaks that come later. The predominant symptom of herpes is the outbreak of painful, itching blisters filled with fluid on and around the external sexual organs or, for oral herpes, on or very near the lip. Females may have a vaginal discharge. Symptoms vaguely similar to those of flu may accompany these outbreaks, including fever, headache, muscle aches and fatigue. There may be painful urination, and swollen and tender lymph glands in the groin.

Usually the blisters will disappear without treatment in two to 10 days, but the virus will remain in the body, lying dormant among clusters of nerve cells until another outbreak is triggered. Factors that can trigger an outbreak include stress, illness such as a cold, fever, fatigue, sunburn, menstruation or sexual intercourse.

Many patients are able to anticipate an outbreak when they notice a warning sign (a tingling sensation, called a prodrome) of the approaching illness. It is when they feel signs that an outbreak is about to start that they are particularly contagious, even though the skin still appears normal

Most people with genital herpes have five to eight outbreaks per year, but not everyone has recurrent symptoms. As time goes on, the number of outbreaks usually decreases. Oral herpes can recur as often as monthly or only one or two times each year.

Sores typically come back near the site of the first infection. Usually, as the outbreaks recur, there are fewer sores and they heal faster and are less painful.

Herpes Simplex


Treatment
Really there is no treatment that completely eliminates body HSV infection, since once the virus enters a body, it will always remain in an inactive form with occasional relapses-recurrences-. There are medications that can reduce the frequency of herpes episodes occur, the duration of these and the damage they cause.

Prophylactic treatment is important to the appearance of outbreaks, contribute to the quick recovery and not infect others:

  • Keep the infected area clean.
  • Do not touch, or touch the sores as little as possible.
  • Wash hands thoroughly before and after contact with the sores.
  • In case of genital herpes, avoid sexual contact since the first symptoms appear until the eruptions have been cured.
  • In case of cold sores, avoid direct contact to other people with the infected area since the first symptoms appear until the eruptions have been cured.
  • Herpes simplex usually responds to topical acyclovir. It is even more effective derivatives acyclovir tablets or orally. If herpes simplex recurrences are common and affect quality of life, then you can give acyclovir or valacyclovir orally every day, what is known as suppressive therapy.

Dementia - Is it Different with Alzheimers?


Are you noticing changes in your cognitive ability?

You might start to think that something's not quite right when a loved one begins to start repeating themselves, becomes agitated easily or forgetting recent events and information.

We here a lot about Alzheimer's and dementia in the media but what do the terms actually mean?
Dementia

It might not be Alzheimer's or dementia

As we grow older, we tend to become more forgetful and that's part of normal aging. Other symptoms, such as depression after the loss of a loved one, or side-effects from medication, can show the same symptoms as people with Alzheimer's or dementia, and so a thorough medical assessment is required as soon as possible after the symptoms manifest.

What does Senile Mean?
Senility is not a disease but simply a generic term for a number of neurological disorders which occur in old age. The word is often used to describe the symptoms of dementia, Parkinson's, etc.


What is Dementia?
Dementia is a brain disorder which leads to the progressive loss of cognitive functions. It affects those areas of the brain which are required for language, reason, and memory functions.

Alzheimer's is the most common form of dementia. Other types of dementia are:

  1. Front Temporal Dementia: it affects the front and temporal lobes of the brain and causes personality and behavioral changes. It manifests between the ages of 40-70 and tends to fun in families.
  2. Vascular Dementia: arteries which feed the brain become blocked or narrow and the symptoms may begin quickly after a person has had a stroke or slowly, occurring at the same time as Alzheimer's, with similar problems with language, memory and vision.
  3. Lewd Body Dementia: This is when abnormal deposits of protein form in the brain, similar to what occurs in Alzheimer's and Parkinson's, with symptoms that include disorientation, muscular rigidity, tremors and slow movement.

Dementia



What is Alzheimer's?
Alzheimer's normally affects people over 65 years old although around 5% of cases are affect people from 35 years up.

Alzheimer's entails a build up of plaques and tangles, which are irregular deposits of protein, which affect the health of brain cells and the way in which they communicate with one another. There is chemical imbalance within the brain which worsens as cells are slowly destroyed. One of the main chemicals which sufferer's lack is called 'acetylcholine', which is a neurotransmitter - it helps to carry messages between networks of cells.

The symptoms of Alzheimer's include memory loss, disorientation, depression, agitation and a withdrawal from social and work activities. Unfortunately, modern medicine can only, at best and for only some, offer palliative care for the patient, making life as comfortable as possible for them.

Alternative treatments and therapies should not be overlooked, including nutritional supplements, doll and music therapy, as they can play an important role of benefiting Alzheimer's sufferers and reduce the requirement for psychoactive drugs.

Aspergers Syndrome


If you are the parent of a child who has signs of autism, and is told that he or she may have Asperger's syndrome, then it's important to understand the characteristics of this condition.

Asperger's syndrome was recognized by the American Psychiatric Association in the year 1944 and has become a abundant well known issue.


There are a number of symptoms associated with both children and adults with Aspergers Syndrome. These symptoms include:

1. Difficulty with social relationships - Many people with Aspergers syndrome have problems in understanding how other people think and feel.They find it difficult to understand facial expressions and all the non-verbal signals people use to communicate in everyday life.

2. Difficulty with communication - People with Aspergers syndrome do not usually have the speech problems experienced by people with classic autism, they can be good talkers. The problems with communication lie in their inability to take notice of the reaction of the people they are talking to; they may continue to talk about one topic even though the other person has become (or never was) interested.

Aspergers Syndrome

3. Lack of imagination - People with Aspergers syndrome often excel at factual work, the kind of work that deals with facts and statistics but they can find it hard to use their imagination. They may have narrow areas of interest that they can become fanatical about and they can become attached to specific routines, for example always doing things in the same order when getting ready to go out in the morning. If for some reason they cannot follow their routine they can become upset and agitated or even angry.


4. Other - Many people with Aspergers also have difficulties dealing with change and may lack what is considered to be basic common sense. However people with the condition are not ‘backward' in any way and usually have average, if not higher than average levels of intelligence.

People with Aspergers syndrome are usually at this more ‘able' end of the spectrum. Like autism, Aspergers syndrome, seems to be caused by a biological difference in the brain's development. In many cases there appears to be a genetic cause; there are many cases of autism and Aspergers syndrome running in the same family. One study has estimated that 3 to 7 in 1,000 people have Aspergers Syndrome.

Depression - How to Fight it


Depression affects an incredible number of individuals world-wide , the fact is, this disorder could be felt by even young individuals these days as a result of a stressful way of living. When depression begins, people’s lives are afflicted since they stop doing their normal regimens.


There are numerous factors that bring about depression such as death of a family member, sudden changes in one’s life, mood-altering medicines, presenting birth, or even seasonal changes. A general symptoms are fatigue, loss of appetite, sleep problems or loss of interest in sex — may seem to be caused by other illnesses, bored, helpless or worthless. They may always want to stay at home, rather than going out to socialize or doing new things.

Depression

Depression symptoms may not get better on their own — and depression may get worse if it isn't treated. Untreated depression can lead to other mental and physical health problems or problems in other areas of your life. Feelings of depression can also lead to suicide.


Suicidal thinking or feelings in older adults is a sign of serious depression that should never be taken lightly, especially in men. Of all people with depression, older adult men are at the highest risk of suicide.

If you're reluctant to seek treatment, talk to a friend or loved one, a health care professional, a faith leader, or someone else you trust.If you or someone you know is having suicidal thoughts, get help right away, seek help from your doctor, a mental health provider or other health care professional.

Popcorn Lung


Popcorn lung disease is a rare and irreversible illness that affects workers who breathe the vapor of butter flavoring, or Diacetyl. Although the formal name of the condition is bronchiolitis obliterans, the condition was named popcorn lung disease or popcorn workers lung because it is most commonly found in employees of microwave popcorn plants.


Popcorn lung disease symptoms include:

  • Scarring and hardening of lung tissue
  • Dry cough
  • Shortness of breath
  • Weight loss
  • Night sweats
  • Fever
  • Skin peeling

Popcorn Lung

When breathing tests are administered to people with possible popcorn lung disease symptoms, they reveal hyperinflation of the lungs because air becomes trapped beyond the obstruction; thickened airway walls; narrow or blocked small airways; reduced ability to expand the lungs fully; and haziness on x-rays.

Popcorn lung disease symptoms include:

Over the last 15 years, a number of popcorn lung sufferers have needed lung transplants to survive and a small handful of people have died. In 2007, four of America's biggest microwave popcorn manufacturers removed diacetyl from nearly all of their products and several smaller companies followed suit.

Cellulitis


Cellulitis is a skin infection caused by bacteria. Normally, your skin helps protect you from infection. But if you have a cut, sore, or insect bite, bacteria can get into the skin and spread to deeper tissues. If it is not treated with antibiotics, the infection can spread to the blood or lymph nodes. This can be deadly.


Some people can get cellulitis without having a break in the skin. These include older adults and people who have diabetes or a weak immune system.

Cellulitis

Symptoms of cellulitis include:

  • Hot, red, swollen and painful area of the skin and deeper tissues
  • Fever
  • Shivers and chills, caused by release of toxins from the bacteria
  • There may be a well-defined line where the cellulitis stops, but this may spread as the infection progresses. Rarely, there's oozing of pus and fluid at the skin puncture site, but usually the infection is more diffuse in the tissues.

Fortunately, cellulitis usually responds well to antibiotics. Ideally, the skin and wound should be swabbed to test the kind of bacteria causing the problem, then a penicillin type of antibiotic is usually needed (or erythromycin for those who are allergic to penicillin).It is very important to get treatment right away for cellulitis. If it is not treated, the bacteria can spread quickly through the body and cause sepsis, an extreme response by the body’s defense system. This can be deadly. Cellulitis on the face can spread to the brain and cause a dangerous infection (meningitis). Cellulitis can also cause other serious problems, such as blood clots in the legs


Cellulitis can be prevented by being careful about hygiene with wounds and breaks in the skin. If you cut or scratch yourself, or break the skin in some way, make sure the wound is cleaned and treated with an antiseptic, then covered with a clean dressing or plaster. If the skin around the wound becomes red and sore, get medical advice as soon as possible.

Addisons Disease


Addison’s disease (also chronic adrenal insufficiency, hypocortisolism, and hypoadrenalism) is a rare, chronic endocrine disorder in which the adrenal glands do not produce sufficient steroid hormones (glucocorticoids and often mineralocorticoids). Addison's disease results when your adrenal glands are damaged, producing insufficient amounts of the hormone cortisol and often aldosterone as well. These glands are located just above your kidneys. As part of your endocrine system, they produce hormones that give instructions to virtually every organ and tissue in your body.
Addisons Disease


Sometimes, however, the signs and symptoms of Addison's disease may appear suddenly. In acute adrenal failure (addisonian crisis), the signs and symptoms may also include:
  • Pain in your lower back, abdomen or legs
  • Severe vomiting and diarrhea, leading to dehydration
  • Low blood pressure
  • Loss of consciousness
  • High potassium (hyperkalemia)

Under certain circumstances, these may progress to Addisonian crisis, a severe illness which may include very low blood pressure and coma.Addison's disease occurs in all age groups and affects both sexes.


Treatment for Addison's disease involves taking hormones to replace the insufficient amounts being made by your adrenal glands, in order to mimic the beneficial effects those naturally made hormones would normally produce.With proper treatment, adrenal crisis usually subsides quickly; the patient’s blood pressure stabilizes, and water and sodium levels return to normal. After the crisis, maintenance doses of hydrocortisone preserve physiologic stability.

Hepatitis C - The Silent Killer


Hepatitis C is an infectious disease affecting primarily the liver, caused by the hepatitis C virus (HCV). The infection is often asymptomatic, but chronic infection can lead to scarring of the liver and ultimately to cirrhosis, which is generally apparent after many years. In some cases, those with cirrhosis will go on to develop liver failure, liver cancer or life-threatening esophageal and gastric varices


TODAY if you have health problems such as flu-like and may include following symptoms, you should immediately consult a doctor.
  • Fatigue
  • Fever
  • Nausea or poor appetite
  • Muscle and joint pains
  • Tenderness in the area of your liver
This is because of the problems you may be infected with an unknown disease is there and there were times when it has reached a chronic stage.

It is difficult to detect infection by the patient's own because it always strikes without bringing specific symptoms or prolonged.
Hepatitis C

The disease is also categorized as a silent killer because many patients do not know they are infected themselves until many years but there is a reach tens of years.

Based on statistics from the World Health Organization (WHO), 60 percent to 70 percent of hepatitis C patients will suffer from chronic liver disease, while five percent to 20 percent will suffer from cirrhosis, while one per cent to five per cent will die from cirrhosis or liver cancer.


Hepatitis C infection is caused by the hepatitis C virus (HCV). HCV is spread when you come in contact with contaminated blood.
  • Blood transfusions and organ transplants before 1992. Improved blood-screening tests became available in 1992. Before that year, it was possible to unknowingly contract hepatitis C through a blood transfusion or organ transplant.
  • Shared needles. HCV can also spread through sharing contaminated needles when injecting drugs.
  • Childbirth. A small number of babies born to mothers with hepatitis C acquire the infection during childbirth.
  • Sexual contact. In rare cases, HCV may be transmitted sexually.
If you receive a diagnosis of hepatitis C, your doctor will likely recommend certain lifestyle changes. These measures will help keep you healthy longer and protect the health of others as well:
  • Stop drinking alcohol. Alcohol speeds the progression of liver disease.
  • Avoid medications that may cause liver damage. Review your medications with your doctor, including the over-the-counter medications you take. Your doctor may recommend avoiding certain medications.
  • Stay healthy. Make healthy lifestyle choices each day. For example, choose a diet full of fruits and vegetables, exercise most days of the week, and get enough sleep so that you wake feeling rested.
  • Help prevent others from coming in contact with your blood. Cover any wounds you have and don't share razors or toothbrushes. Don't donate blood, body organs or semen, and advise health care workers that you have the virus.

Blood Pressure


Blood pressure (BP), sometimes referred to as arterial blood pressure, is the pressure exerted by circulating blood upon the walls of blood vessels, and is one of the principal vital signs. When used without further specification, "blood pressure" usually refers to the arterial pressure of the systemic circulation. During each heartbeat, blood pressure varies between a maximum (systolic) and a minimum (diastolic) pressure.The blood pressure in the circulation is principally due to the pumping action of the heart.



Blood pressure readings fall into four general categories, ranging from normal to stage 2 hypertension (high blood pressure). The level of your blood pressure determines what kind of treatment you may need. To get an accurate blood pressure measurement, your doctor should evaluate your readings based on the average of two or more blood pressure readings on each of two office visits.

Blood Pressure

The top number is your systolic pressure.
It is considered high if it is over 140 most of the time.
It is considered normal if it is below 120 most of the time.


The bottom number is your diastolic pressure.
It is considered high if it is over 90 most of the time.
It is considered normal if it is below 80 most of the time.
Pre-hypertension may be considered when your:

Top number (systolic blood pressure) is between 120 and 139 most of the time, or
Bottom number (diastolic blood pressure) is between 80 and 89 most of the time

If you have pre-hypertension, you are more likely to develop high blood pressure.

If you have heart or kidney problems, or if you had a stroke, your doctor may want your blood pressure to be even lower than that of people who do not have these conditions.

West Nile Virus


West Nile Virus (WNV) was first identified in the West Nile sub-region in the East African nation of Uganda in 1937

West Nile virus is caused by a bite from an infected mosquito that's already carrying the virus, but it's important to remember that not all mosquitoes are infected,it is a mosquito-borne zoonotic arbovirus belonging to the genus Flavivirus in the family Flaviviridae. This flavivirus is found in temperate and tropical regions of the world. In many parts of the United States, the risk of being bitten by an infected mosquito is greatest from July to early September. But in some parts of the country, mosquito bites can be a risk all year long.


Not everyone who gets bitten by an infected mosquito will get the virus, from studies we know that only about one in every five people who get infected with West Nile will actually develop symptoms.

The most common ones are
- Fever
- Headaches
- Body ache
- Joint pain
- Vomiting
- Diarrhea
- Rash
West Nile Virus

A lot of people who develop symptoms usually just wait it out at home. Or they’ll go to a medical doctor and end up recovering from their illness and feeling much better within several weeks. Sometimes, people will complain of fatigue or report feeling not quite themselves for several months.


If they think they have West Nile, they can have their blood tested for the presence of antibodies or, in more severe cases that affect the central nervous system, a doctor can take samples of the cerebrospinal fluid that surrounds the brain and spinal cord.Usually people are hospitalized if they have more serious symptoms.West Nile virus is not spread from person to person.
West Nile Virus

So, what's being done to stop the spread of West Nile virus? Health officials in each state do their best to find out where mosquitoes live and kill the eggs of mosquitoes that might carry the virus.Watch out for mosquitoes in the early morning and in the early evening since that's when they're often very active. Mosquitoes also like standing water, like in wading pools and creeks.Use insect repellents when you go outdoors. Wear long sleeves and pants to prevent mosquito bites at dusk and dawn. Install or repair screens or windows to prevent mosquitoes from getting inside your home.

Bubonic Plague


There are three most common forms of plague are:

  1. Bubonic plague -- an infection of the lymph nodes
  2. Pneumonic plague -- an infection of the lungs
  3. Septicemic plague -- an infection of the blood


Bubonic plague is a zoonotic disease, c is caused by the bacteria Yersinia pestis. Rodents, such as rats, carry the disease. It is spread by their fleas.Without treatment, the bubonic plague kills about two thirds of infected humans within 4 days.

Plague causes fever and a painful swelling of the lymph glands called buboes, which is how it gets its name. The disease also causes spots on the skin that are red at first and then turn black.


According to the World Health Organization, there are 1,000 to 3,000 cases of bubonic plague worldwide each year. There are no known cases in Australia or Europe. Plague can still be found in Africa, Asia, and South America.

The U.S. Centers for Disease Control and Prevention (CDC) reports that there are 10 to 15 cases of bubonic plague in the United States each year. These cases tend to occur in two regions: northern New Mexico, northern Arizona and southern Colorado; California, southern Oregon and far western Nevada.

Bubonic Plague

Bubonic plague symptoms appear suddenly, usually after 2 - 5 days of exposure to the bacteria. Symptoms include:

  • Chills
  • Fever
  • General ill feeling (malaise)
  • Headache
  • Muscle pain
  • Seizures
  • Smooth, painful lymph gland swelling called a bubo


People with the plague need immediate treatment. If treatment is not received within 24 hours of when the first symptoms occur, death may occur.


Antibiotics such as streptomycin, gentamicin, doxycycline, or ciprofloxacin are used to treat plague. Oxygen, intravenous fluids, and respiratory support usually are also needed.

Patients with pneumonic plague should be strictly isolated from caregivers and other patients. People who have had contact with anyone infected by pneumonic plague should be watched carefully and given antibiotics as a preventive measure.




In most developed countries, cities and towns have successfully controlled their rat populations, but rural and urban areas of developing countries often have problems with rat infestation, and thus are at risk of bubonic plague epidemics. Therefore, reducing the risk of plague outbreaks in these areas would require:

  • Controlling the rat population
  • Watching for plague cases in both rats and humans in the area
  • Using insecticide to reduce the number of fleas
  • Treating pets for fleas

HIV/AIDS

HIV/AIDS
HIV (Human Immunodeficiency Virus) is a virus that causes AIDS (Acquired Immunodeficiency Syndrome), a condition that breaks down a person’s immune system leading to a series of diseases. HIV does not instantly lead to AIDS. An HIV infected individual can lead a healthy life for several years before developing AIDS. HIV may be passed to another person when infected blood, semen or vaginal fluids come in contact with skin tears or mucus membranes of an uninfected individual.


According to the Mayo Clinic, an estimated 38.6 million people are living with HIV. Nearly half of them are women and girls between the ages of 15 and 24. In 2005, more than 4 million people were diagnosed with new cases of HIV. Twenty-five million people have died of AIDS (advanced stage of HIV) since the epidemic began about 25 years ago.

What are the symptoms of HIV?
The first symptoms of HIV can resemble symptoms of other conditions, such as a cold or flu virus, other sexually transmitted diseases, other infections such as mononucleosis or hepatitis. Stress and anxiety can also produce symptoms that are similar to HIV in some individuals.
The intensity of the symptoms can also vary from person to person. Some may experience very strong symptoms while others experience none at all. General symptoms can occur within days or weeks of initial exposure to the virus and may include:
Fever
Fatigue
Rash
Headache
Swollen lymph nodes
Sore throat
These symptoms usually appear during a period called primary or acute HIV infection.

The following may be warning signs of advanced HIV infection:
Rapid weight loss
Dry cough
Recurring fever or profuse night sweats
Profound and unexplained fatigue
Swollen lymph glands in the armpits, groin or neck (lymphadenopathy)
Diarrhea that lasts for more than a week
White spots or unusual blemishes on the tongue, in the mouth, or in the throat
Pneumonia
Red, brown, pink or purple blotches on or under the skin or inside the mouth, nose or eyelids
Memory loss, depression and other neurological disorders
No one should assume they are infected with HIV just because of these symptoms. Each of these symptoms can be related to other medical conditions. Because these symptoms are similar to other diseases, a person may not realize they are infected with HIV. The only way to determine if a person is infected with HIV is to be tested.
Even if someone doesn’t have symptoms it is still possible to transmit the virus to others. Once the virus has entered the body it begins to attack the immune system. The virus multiplies in the lymph nodes and begins to destroy the T-cells, which are the white blood cells that coordinate the entire immune system.
A person may be symptom free for nine years or more. During this time the virus continues to multiply and destroy immune cells.

Can having HIV lead to other problems?
The advanced stages of HIV have been identified by the term AIDS (Acquired Immunodeficiency Syndrome). According to the definition provided by the Centers for Disease Control & Prevention (CDC), AIDS includes all HIV-infected people who have less than 200 CD4+ T cells per cubic millimeter of blood. This definition also includes 26 clinical conditions that affect people with advanced HIV disease. In people with AIDS, these infections are often severe and fatal because the immune system has been so damaged by HIV that the body cannot reject certain bacteria, viruses, fungi, parasites and other microbes.

How is HIV transmitted?
The most common ways that HIV is spread include:
Vaginal, oral or anal sex with someone who is infected with HIV
Sharing needles or syringes with someone infected with HIV
Infected blood, semen or vaginal fluid (including menstrual blood) can enter the body through the vagina, rectum or mouth and surrounding tissue. The risk of becoming infected increases if there are sores (caused by herpes, syphilis and chancroid) on the genitals (vagina, vulva, penis). Sharing personal devices can be risky if they have been in contact with another person’s blood, semen or vaginal fluid.

HIV is not spread through every day activities or casual contact. Activities such as hugging, kissing, cuddling, touching or massaging do not spread HIV unless there is contact with the person’s blood, semen, vaginal fluid or breast milk.

HIV cannot be contracted from:
Food
Handshakes
Coughs or sneezes
Being around an infected person
Insect bites
Using swimming pools or hot tubs
Toilet seats
Phones or computers

How is HIV diagnosed?
Because this disease has nonspecific symptoms, they are not a reliable way to diagnose HIV infection. The only way to know whether a person has been infected is through HIV testing.
HIV tests do not test for the actual HIV virus. One test detects HIV proteins while the other two detect HIV antibodies in the bloodstream.
Elisa is the first portion of the HIV test. This test detects the presence of HIV antibodies in the blood. Negative results determine a person is not HIV infected. Positive results lead to the second portion of the test to confirm results.
Western Blot is used to confirm a positive Elisa test result. The Western Blot test detects specific protein bands that are present with HIV infections. A positive Elisa test with a positive Western Blot test gives 99.9% accuracy in identifying HIV infection.
PCR detects specific DNA and RNA sequences that indicate the presence of HIV in the genetic structure of anyone HIV infected. DNA and RNA from the HIV virus circulate in the blood. The presence of these “particles” indicates the HIV virus.
Testing for HIV antibodies is the only way to know if a person is infected. However, this test for HIV antibodies is effective only after the infected person’s immune system produces antibodies to HIV. There is a time period between the initial infection and when the HIV antibodies are detectable which can be from 2 weeks to 6 months with an average length of 3 months. During this time period standard HIV testing is ineffective.

What is the treatment for HIV?
When the HIV/AIDS epidemic began in the early 1980s, AIDS patients were not expected to live more than a few years. Since then, the development of safe and effective drugs is enabling people with HIV to live longer and healthier lives.
At the present time there are 26 antiretroviral drugs that have been approved by the U.S. Food and Drug Administration (FDA) for the treatment of HIV patients. These drugs can be classified into three major groups:
Reverse transcriptase (RT) inhibitors – interfere with the conversion of reverse transcriptase (an HIV enzyme) into HIV RNA to HIV DNA.
Protease inhibitors (PI) – interfere with the protease enzyme that HIV uses to produce infectious viral particles.
Fusion inhibitors – interfere with the HIV virus’ ability to fuse with the cellular membrane, thus blocking entry into the host cell.
Current drugs can suppress the HIV virus, even to undetectable levels, but are not able to completely remove HIV from the body. These drugs help to manage HIV but are not able to cure it. It is important that infected patients continue to take antiretroviral drugs.
Because HIV reproduces itself, new strains of the virus continue to emerge which can be resistant to antiretroviral drugs. Most health care providers recommend that HIV infected patients take a combination of antiretroviral drugs known as HAART. This combination of drugs successfully suppresses the virus and decreases the rate of opportunistic infections by strengthening the immune system.
While the use of HAART can suppress the virus and has greatly reduced the number of deaths due to HIV/AIDS, the virus may still be transmitted. People infected with HIV who are taking antiretroviral drugs can still transmit HIV to others through unprotected sex and needle sharing.
The Pharmaceutical Research and Manufacturers Association of America maintains a database of new drugs in development to treat HIV infection. Scientists are also studying how immune modulators can help to increase the immune response to the HIV virus and make existing HIV drugs more effective. Therapeutic vaccines are being examined for this purpose.

Can HIV be prevented?
Not having sex is the only sure way to avoid the transmission of HIV.
If you decide to engage in sexual activity, in order to reduce the risk of infection you should:
 Have sex with only one partner who is not infected with HIV, who does not share needles or syringes and who has sex only with you. These things may be difficult to know about another person.
Avoid contact with your partner’s blood, semen or vaginal fluid.
The correct use of a latex condom when having sex greatly reduces your risk of HIV infection.
Use a water-based lubricant with the latex condom to reduce risk of breakage when engaging in vaginal or anal sex.
Use a male condom without spermicide or a lubricant for oral sex.
Further research is needed to determine the effectiveness of the female condom or dental dams in preventing HIV transmission.

Four Things You Do That Kill Her Sex Drive


There’s a reason why you and your wife of 20 years don’t ravage each other anymore, and it isn’t for your lack of trying. According to a new study in the Journal of Sex & Marital Therapy, women in a committed relationship report lower levels of sexual desire over time—a .02 percent decrease every month—while a guy’s desire stays the same. (Yet another reason to start with a lusty woman to begin with!)
“Some research suggests that somewhere between 6 and 30 months, relationships switch from passionate to compassionate—more affectionate than ripping each other’s clothes off,” says lead study author Robin Milhausen, Ph.D., a sex researcher at the University of Guelph in Ontario.
So are you to blame for her lack of lust? Not necessarily, Milhausen says. “For women with a lower sex drive in the first place, the switch to a deeper emotional bond may reduce some of the excitement associated with sex in new relationships.”

Still, you’re not exactly helping matters. We asked several sex experts to shed light on the worst things you do around the house and in the sack that turn her off. Vow to never commit the following mood-killers again—try to Banish These Bad Habits, too—and your sex life will suffer no more.

1. Ignoring Her Appearance
Guys in long-term relationships tend to stop noticing when their partner looks pretty, and so much of female sexual desire is tied to a sense of self-esteem,.. The fix here is simple: Pay her a few simple compliments every day, like letting her know she’s sexy.

2. Putting Her Under Pressure
Don’t worry or question her about getting orgasms, says Marnia Robinson, author of Cupid’s Poisoned Arrow. Stay relaxed and focused on playful touching, she advises. “This means no performance pressure on either of you. Let whatever happens happen in its own time—or not. Good sex is about connection and sensual satisfaction, not number of orgasms produced.

3. Using Porn As a Benchmark
It’s good to keep the sex hot—but it’s more important to keep it real. In other words, forget that cool move you caught on XTube.  ”Just because you saw a sexual practice in a film doesn’t mean it’s safe or satisfying,” says Robinson.  And it might not even be something she’s into. “If you need extreme stimulation to perform with a partner, you may want to cut back on overstimulation. A desensitized brain can also find sex less arousing. As you restore your brain to normal sensitivity, regular sex behaviors become enjoyable again.” Time to rediscover the wonders of the missionary position. (Need more help finding great moves?

4. Leaving Her Lips Hanging
As men get comfortable in a relationship, their approach to foreplay tends to focus on the moments leading up to sex, But female desire doesn’t operate like a light switch that turns on and off—it’s more like a dimmer,” he says. Small acts of intimacy like hugging and kissing can get her in the mood. But don’t get antsy: “Don’t expect her to be immediately turned on.

Weight loss may boost men's testosterone


For some men, weight loss plays an important role in raising low testosterone levels, a new study finds.
In the study of overweight, middle-aged men with prediabetes, about half of those with low testosterone levels who attempted to lose weight by changing their lifestyle experienced an increase in their testosterone levels.

The findings suggest "doctors should first encourage overweight men with low testosterone levels to try to lose weight through diet and exercise, before resorting to testosterone therapy to raise their hormone levels," said study researcher Dr. Frances Hayes, a professor at St. Vincent’s University Hospital, Dublin.

Hayes and colleagues analyzed information from nearly 900 men with prediabetes — a condition in which blood sugar levels are abnormally high, but not high enough to be classified as Type 2 diabetes. The men's average age was 54.

The men were randomly assigned to receive one of three treatments: the diabetes drug metformin, an inactive placebo pill or lifestyle modifications, which consisted of exercising for 150 minutes a week and eating less fat and fewer calories. The researchers said they considered men to have low testosterone if their levels were below 300 nanograms per deciliter of blood.
Among the men assigned to change their lifestyle, about 20 percent had low testosterone levels at the study's start. After one year, that number fell to 11 percent.
Among those taking metformin, 24.8 percent had low testosterone at the beginning of the study, and 23.8 percent still had the condition a year later. For the placebo group, the rate fell from 25.6 percent to 24.6 percent during the study.
Men in the lifestyle modification group lost an average of about 17 pounds over the one-year study, and testosterone levels among men in this group increased 15 percent on average, the researchers said. (Men in the metformin group lost about 6 pounds.)
Losing weight not only reduces the risk of prediabetic men progressing to diabetes but also appears to increase their body's production of testosterone

Why antibiotics may not help most sinus infections



Ask any scientist to list history's greatest discoveries, and he or she will likely include antibiotics. Antibiotics are medicines made from certain bacteria, fungi or other organisms that can kill or weaken other organisms that attack our bodies. Penicillin is the first and most well known antibiotic. Since its discovery, countless lives have been spared from diseases that used to be killers.
For a time, antibiotics were thought to cure almost everything, even cancer. While it would be great, we now know this isn't true. And we're learning more every day. Like this: A new study says that antibiotics may not cure most sinus infections.

What is sinusitis?
It's often called a "sinus infection," and it means there's inflammation or swelling in one or more of a person's sinuses. Sinuses are small spaces in the forehead and cheekbones. They're filled with air, and their job is to make mucus. When we're healthy, this mucus drains into our noses. When our sinuses are inflamed, the drainage stops and the misery starts. Then we have sinusitis – an infection of our sinuses.
Many things can cause sinusitis. That's why one thing may not be enough to treat it. Allergies, pollen, bacteria, pollution, dust, viruses – the list of what can irritate our sinuses and set off an infection goes on and on.

Signs of sinusitis include:
Headaches
Nasal congestion
Runny nose/nasal discharge
Postnasal drip (mucus drips down the throat from the nose)
Sore throat
Fever
Cough
Fatigue
Bad breath


Sinusitis is so common in the United States that 1 of every 5 antibiotic prescriptions written is to treat it. But it looks like those prescriptions may not be the right answer in many cases.
Bacteria and viruses: two different things

There are two "usual suspects" doctors turn to first when dealing with an illness. The first group is bacteria. The second is viruses. Bacteria and viruses aren't the same things. So, bacterial infections and viral infections aren't the same, either.
Unfortunately, antibiotics don't work on a viral infection. That's why doctors don't always give us prescriptions for antibiotics: sometimes we have something viral.
Now, researchers are finding that sinus infections can be either bacterial or viral.
And lately, more scientists seem to be thinking that viruses are to blame for most sinus infections.
A new medical study: antibiotics don't work on sinus infections.

The most conclusive study so far was published in the February 15, 2012 . It's by the Washington University School of Medicine in St. Louis and covered 166 adults with sinus infections. Over 10 days, one group of patients was treated with amoxicillin, a popular antibiotic. The other was treated with a placebo, which is a "fake" pill sometimes called a sugar pill. If they needed it, both groups also got over-the-counter remedies for their symptoms – headache, stuffy nose and sinuses, coughs, fever, etc.
At the end of the 10 days, it was clear that patients taking amoxicillin didn't feel better sooner, or recover any faster, than those who were getting the placebo.
Dr. Jane M. Garbutt, the study's lead author, said, "We hope this study provides scientific evidence that doctors can use with patients to explain that an antibiotic is not likely to help an acute sinus infection."
"I think more often than not, these infections are viral, so antibiotics aren't going to help," Garbutt said. While some sinus infections may actually come from bacteria, she said, it's hard to tell a bacterial infection from a viral one. Basically, the only way to know is to draw a sample from a person's sinus, and that would take surgery.
The United States Centers for Disease Control and Prevention (CDC) agrees. The CDC's website says viral sinusitis often occurs after a cold (which is a virus) and usually lasts for less than four weeks. Bacterial sinusitis can cause symptoms for up to 12 weeks.
No matter which kind you may have, a growing number of experts think it's best to watch and wait.
Why not take antibiotics just in case?

Besides the fact that taking antibiotics for sinusitis means spending money on medicine that may not help you, more and more studies say you could be risking your future health. Why?
It appears that more and more kinds of bacteria aren't being killed by antibiotics anymore. In medical terms, they're becoming "resistant" to the drugs.
Each time you take an antibiotic, the bacteria that usually live in your body are more likely to become resistant to antibiotics. In time, common antibiotics can't kill infections caused by these resistant germs.
The CDC is very concerned about resistance to antibiotics. From a public-health point of view, resistance could be a disaster. Overuse of antibiotics has already led to the rise of drug-resistant infections like MRSA (Methicillin-Resistant Staphylococcus Aureus). Fighting MRSA is creating a lot more work at hospitals these days.
So while sinus infections make us feel terrible, if we were to build resistance to antibiotics by over-using them to treat sinus infections, what might happen if we're faced with a bacteria-caused epidemic and no one responds to the drugs?
If you'd like to learn more about this very important issue, the CDC offers an excellent series of questions and answers about antibiotic resistance here. It really is something we all need to think about.
Researchers know people aren't going to like this "wait and see" approach to such a "nasty disease," as Garbutt describes it. She said: "People have significant symptoms. They feel miserable and miss time from work. If an antibiotic is not going to be of any benefit, then what is? That's a question we haven't answered yet. But we are working on it."
Bottom line?

The CDC says a doctor should never give an antibiotic until symptoms have gone on for at least seven days. In light of this new research, your doctor may want to wait even longer before writing a prescription. Even though it may not be what you want, if your doctor wants to wait, he or she is doing it for your long-term health. Besides: if your sinusitis is viral, an antibiotic won't help anyway.
Other options for relief

Some people say they feel less congested when they drink hot fluids. Others find some relief from warm, wet compresses on their faces. Still others use warm-water vaporizers. Decongestant nasal sprays can help, though no one should use them for more than a few days. It's too easy to become dependent on them.
Several safe and "more-natural" options are out there, and many people report good results with them. One choice is a saline (salt) nasal spray. Another is a "neti pot." A neti pot looks like a little teapot. Its spout is used to gently pour warm saline solution – a mix of salt and water – into the nostrils. Neti pots, saline sprays, and their cousins, the more-powerful saline nasal rinses can help flush mucus out of sinuses. Clearing mucus, especially infected mucus, out of clogged sinuses brings great relief.
Over-the-counter medicines like ibuprofen can help ease sinus swelling and the face pain it brings. But doctors say you should also try to clear your nasal passages, because it will help ease symptoms and clear the infection.

When to see a doctor, recommends you see a doctor or healthcare provider if you have:
A temperature of more than 100.4° F.
Symptoms that last more than 10 days.
Multiple episodes of sinusitis in a year.
Symptoms that over-the-counter medicines can't ease.
If your child is younger than three months of age and has a fever, always call your healthcare provider right away.

Top 5 ways to avoid a sinus infection
Keep your hands clean – regular hand washing is still the best way to fight disease.
Keep yourself and your family up to date with recommended immunizations.
Avoid close contact with people who have colds or other upper respiratory infections.
Avoid smoking or being exposed to second-hand smoke, and don't expose children to second hand-smoke.
Use a clean humidifier to moisten the air at home.

Is Your Penis Curving?


What causes the curve?
Peyronie’s occurs due to a plaque that builds up in your penis, says Dr. Carson. It typically starts out as a localized inflammation, which then progresses to hardened scar tissue that reduces flexibility and causes your penis to bend during erection. “Peyronie’s disease can often result from an injury during sex,” Dr. Carson says. But realistically, anything that causes vascular trauma or injury to the penis, such as athletic activity or an accident, can receive the blame,


How does it affect your package?
Once the scar tissue begins to harden into a plaque, the tissue tethers the shaft into a curved position, because that section is no longer as elastic as the rest of the penis. “The curve can be anything from minimal up to almost 90 degrees,” says Dr. Carson. “The [penises] that usually need treatment have 30 degrees or more of curvature.”

Can it screw up your sex life?
You bet. Things start getting painful when your penis becomes erect, making sex more difficult for you and your partner, says Dr. Carson. But the pain associated with an erection usually only lasts for the first 4 to 6 months. So most men can continue sex, but it’s just not as pleasurable

What are the current treatment options?
Unfortunately, there are no approved oral medications that actually work, Dr. Carson says. Patients are usually put on Potaba, a drug that reached the market before the FDA required proof of effectiveness. “When oral treatments don’t work, which they usually don’t, docs recommend Interferon, another injected treatment,” says Dr. Carson. But again, Interferon can’t guarantee a cure.
Case in point: One study, published in the journal European Urology, found that after treating 25 Peyronie’s partients with injections for five weeks, researchers saw a 28 percent decrease in the size of the plaque. Yet when the same researchers conducted the study 2 years later on a group of 30 men, no decrease in plaque size was reported.
If the docs exhaust every other option (and the case is extreme enough), surgery is a last resort. “There are three basic operations that we do: Two are based on just straightening the penis, and the third is a penile implant,” says Dr. Carson. But again, he pegs surgery at a 75 percent success rate, and each option may lead to erectile dysfunction and shortening of the penis

4 Ways to Look Younger


Botox isn’t just for sugar mamas: Between 2000 and 2'ber of men undergoing the procedure skyrocketed 258 percent, according to the American Society of Plastic Surgeons.
Wrinkly, aged skin is never sexy, but then neither is a frozen face. Even if you don’t have a needle phobia, brotox comes with a hefty price tag and some serious recoup time. So avoid the needles—here are four natural ways to instantly look younger and sharper


Build Your Brows
Neglect your brows and you can wind up looking a helluva lot older than you are. Groom them correctly, and you’re left with an instant lift around your eyes, says Katy Walsh of Salon Pour Hommes in New York City. Remember: “Work with what you have,” recommends Jessica Coba, CEO and cofounder of European Wax Center. “If your brows are naturally straight, stick with that. If they have a bit of an arch, shape it up as best you can.”

Exfoliate
The older we get, the less hydrated our skin becomes, says Coba. The consequence: dead skin cells and a dull appearance. Exfoliate to slough away dead skin and leave the area rejuvenated, she says. The ingredient  to look for in an exfoliant: hyaluronic acid. “It holds moisture, and fruit enzymes remove dead skin cells and promote cell turnover

Add Water
Hydrating your skin takes more than slabbing on lotion. Make it a morning and nightly routine to lock in moisture for good.
