Blood Pressure Education Month

May is High Blood Pressure Education Month.

"Hypertension is considered the "silent killer" because it can damage the heart, brain, and kidneys without any symptoms. Each day in the United States, nearly 1,000 deaths are associated with hypertension," says the Center for Disease Control (CDC). "National High Blood Pressure Education Month aims to save lives by increasing awareness and educating the public about cardiovascular risks and how to prevent them."

Five of our UI Health Pharmacies listed below have self-monitoring blood pressure machines in the waiting rooms, additionally our pharmacists are trained to provide counseling on high blood pressure disease and the medication used to treat this.

Measles 101: The Facts You Need to Know

Measles is a highly contagious respiratory illness caused by the measles virus.^1-3  The illness is characterized by fever, cough, runny nose and rash.  Although measles is no longer present regularly in the United States (U.S.), sporadic outbreaks still occur.  The number of cases has been drastically reduced by the measles vaccine.

What are symptoms of measles?

Initial symptoms of measles include fever, cough, muscle aches, pains, stuffy nose, and red eyes.^1-3 After the initial onset of symptoms, Koplik spots (blue-grey spots on a red background) appear inside the mouth.^2,3  A  rash can develop 2 to 4 days after onset of the fever. It can appear first on the head and face, and then spread to the trunk and extremities.^1-3  Symptoms can develop 7 to 21 days after exposure to the measles virus.^1,4

How common is measles?

Since 2000, measles has been declared eliminated from the United States by the Centers for Disease Control and Prevention.¹  However, cases continue to be reported in the U.S. due to an increase in the number of unvaccinated persons and  transmission from other parts of the world.^1-3  As of February 2015, 170 current cases had been reported in the U.S., 15 of which were in the state of Illinois.^5,6 Worldwide, it is estimated that 20 million people are infected with measles each year, and 146,000 die from the illness.¹ 

How is measles diagnosed?

Measles is suspected in patients with characteristic symptoms.^1,2  Confirmatory diagnostic tests include blood, throat, mouth, nose, and urine testing.  Exposure to persons with measles and potential travel should also be considered when evaluating symptoms.

How does measles spread?

Once a measles infection has developed, the virus lives in the lungs, mouth and nose.  It is highly contagious and can be spread by coughing and sneezing.¹  The virus may remain in the air or on a surface for up to 2 hours after an infected person leaves an area.  Spread of measles has been reported in physician offices, daycares, amusement parks, and sports complexes.^1-5  The virus is particularly stable in times of low humidity, which may account for a higher incidence of measles during the winter months.³  It is estimated that 9 out of 10 susceptible people who are within close contact of a person with measles will develop the disease.¹ 

How can measles be prevented?

Measles can be prevented with administration of a measles virus-containing vaccine.^1-3  It is administered as 2 doses of a combined measles, mumps, and rubella (MMR) vaccine.^1-3,7,8  Within 2 to 6 weeks, the vaccine induces production of antibodies against these viruses in 97% of children.⁸  

Persons who are considered protected from measles include the following:⁷  

• Immunization records of 2 MMR vaccine doses
• Documented bloodwork confirming immunity against measles
• Documentation of previous measles infection
• Born prior to 1957

Individuals who do not fall into these categories should consult with a physician regarding their need for measles vaccination. 

In children, the first dose of the MMR vaccine is administered at 12 to 18 months of age, followed by a second dose at 4 to 6 years.^1,2,7,8  Children younger than 12 months do not have a mature immune system and cannot produce an adequate response to the vaccine.^3,7,9  The MMR vaccine is safe and effective, and adverse reactions are generally mild and temporary.^2,7  Serious  side effects are rare, but common adverse reactions include burning, stinging, pain, hardening of skin, and redness at the injection site.⁸  Symptoms that mimic the measles infection with fever and rash are also possible.^3,8  

Very rarely, adverse effects involving the central nervous system may occur; however, the risk of this type of severe reaction is much less with the vaccine than with an actual measles virus infection.⁸  Despite concerns voiced by certain consumer advocate groups, the medical and scientific communities have extensively evaluated all available data and concluded that the MMR vaccine is not linked to autism spectrum disorders or bowel disease.^2,3,7,8,10

In the U.S., each state mandates vaccination of children older than 5 years prior to enrolling in public schools and daycares.¹⁰  There are possible exemptions that different states may offer, which can be classified as medical contraindication, religious, and philosophical.  The submission and review processes for obtaining an exemption vary by state.

How is measles treated?

There is no specific medication to treat infection with the measles virus.^1-3 Treatment of infected individuals is directed toward management of symptoms and prevention of possible associated bacterial infections. Fevers that lead to discomfort can be treated with acetaminophen or a nonsteroidal anti-inflammatory medication, such as ibuprofen.¹¹  It is also important to stay hydrated through consistent fluid intake.  Pharmacists or other medical professionals can be consulted for further recommendations on anti-fever product selection and dosing.

People with measles can spread the virus in the 4 days before and after the onset of rash.^1,2,4  People who have symptoms consistent with measles should remain isolated from others, at least through the fourth day after rash development.  Exposed individuals should notify their local health department if symptoms occur.

Individuals who have been exposed to measles may be eligible for preventative therapy within 3 to 6 days of exposure.^1,2,4  These measures may offer protection or modify the disease course.  Individuals in this situation should contact a physician as soon as the exposure has been identified.  If preventative therapy is given, the patient cannot return to a healthcare setting and must be excluded from high risk settings, such as infant childcare,  for 21 days after the exposure to maintain effectiveness of the preventative treatment.^1,4  Development of symptoms should be monitored for an additional 7 days after the 21 day quarantine.⁴  Healthcare workers who are not immune to measles should be excluded from the healthcare setting from 5 days after the first measles exposure to 21 days after the last measles exposure.^1,4

What are possible complications of measles?

Possible complications include ear, throat, and lung infections, as well as diarrhea.^1,2  Pneumonia is the most common complication of measles that causes death.²  Rarely, complications involving the central nervous system can occur.^1-3  Headaches, seizures, or changes in behavior or consciousness may indicate these complications.  Complications can occur from 2 days to 15 years after exposure to the measles virus.²  Children less than 5 years of age, adults older than 20 years of age, pregnant women, and individuals with a decreased immune system are at the highest risk of developing complications from measles infection.¹ In children, 1 to 2 deaths occur from respiratory or nervous system complications out of every 1,000 cases of measles.

Extreme Cold Weather Tips

As we head back into the deep freeze this week, here’s 15 safety tips that we’ve compiled from the American Red Cross and the CDC that you can use to stay safe and warm during the cold weather.

1. Layer up! Wear layers of lightweight clothing to stay warm. Gloves and a hat will help prevent losing your body heat.

2. Don’t forget your furry friends. Bring pets indoors. If they can’t come inside, make sure they have enough shelter to keep them warm and that they can get to unfrozen water.

3. Take a buddy and an emergency kit when you are participating in outdoor recreation.

4.  Work slowly when doing outside chores.

5.  Sprinkle cat litter or sand on icy patches.

6. Remember the three feet rule. If you are using a space heater, place it on a level, hard surface and keep anything flammable at least three feet away – things such as paper, clothing, bedding, curtains or rugs.

7. Leave your home immediately if the CO detector sounds, and call 911.

8.  Keep grills, camp stoves, and generators out of the house, basement and garage.

9.  Turn off space heaters and make sure fireplace embers are out before leaving the room or going to bed.

10. Don’t catch fire! If you are using a fireplace, use a glass or metal fire screen large enough to catch sparks and rolling logs.

11. Protect your pipes. Run water, even at a trickle, to help prevent your pipes from freezing. Open the kitchen and bathroom cabinet doors to allow warmer air to circulate around the plumbing. Be sure to move any harmful cleaners and household chemicals out of the reach of children. Keep the garage doors closed if there are water lines in the garage.

12. Better safe than sorry. Keep the thermostat at the same temperature day and night. Your heating bill may be a little higher, but you could avoid a more costly repair job if your pipes freeze and burst.

13. The kitchen is for cooking. Never use a stove or oven to heat your home.

14. Use generators outside. Never operate a generator inside the home, including in the basement or garage and keep generators 20 feet from the house.

15. Knowledge is power. Don’t hook a generator up to the home’s wiring. The safest thing to do is to connect the equipment you want to power directly to the outlets on the generator.

Hope these tips help you, please share them with family and friends and stay warm!

Celiac Disease and Gluten—What is the Connection?

What is celiac disease?

Celiac disease is an autoimmune condition where the intake of gluten causes the body’s immune system to attack the healthy lining of the small intestine.¹ Celiac disease is also known as gluten-sensitive enteropathy, celiac sprue, and nontropical sprue.² Celiac disease is a type of gluten-related disorder. Other gluten-related disorders include non-celiac gluten sensitivity and wheat allergy.³

How common is celiac disease?

Celiac disease occurs mostly in Caucasians of European descent and is estimated to affect approximately 0.5% to 1% of population worldwide.^4,5 Celiac disease is relatively rare among those of Chinese, Japanese, Korea, and African heritage.⁵ The disease can occur in people of any age and is 2 to 3 times more common in women than men. Celiac disease is hereditary and the incidence (which is the number of newly diagnosed cases of a disease) is approximately 5% to 10% in first-degree relatives of patients with celiac disease.^2,4,7

What is gluten? How does it cause celiac disease? 

Gluten is a protein that can be found in wheat, rye, or barley, as well as the many foods made with these grains. Gluten can also be found in oats that may be contaminated with wheat, rye, or barley during processing. Some medications may also contain gluten.^{1, 2}

Celiac disease occurs in individuals who have a sensitivity to gluten due to their genetic makeup. The body’s immune system usually acts to protect the body from disease and infections. However, in celiac disease, the ingestion of gluten by susceptible individuals causes the body’s immune response to abnormally produce antibodies and other substances that damage the cells lining the small intestine, adversely affecting the small intestine’s role in nutrient absorption from food.⁶  This increases the risk of nutritional deficiencies and other complications such as fatigue, anemia (low red blood cell count), and osteoporosis.^1,2 In addition, celiac disease has been found to be associated with a severe skin rash known as dermatitis herpetiformis and other conditions such as diabetes mellitus type 1 and thyroiditis.^1,4

What are the symptoms of celiac disease?

The presentation of celiac disease is wide-ranging and has been likened to “an iceberg”, with a small group of individuals with classic disease who present with symptoms of malabsorption, diarrhea, and weight loss; and a larger group of individuals who may only display minor gastrointestinal symptoms and other nongastrointestinal-related symptoms such as anemia, osteopenia, infertility, and neurological symptoms (atypical celiac disease). Many individuals with celiac disease may experience no symptoms at all (silent celiac disease).^4,7 

The symptoms of celiac disease can include^1,2,7,8:

§  Gastrointestinal symptoms (abdominal bloating, pain, gas, diarrhea)

§  Weight loss

§  Severe skin rash

§  Anemia

§  Joint and bone pain

§  Tingling and numbness in the fingers or legs

How is celiac disease diagnosed?

Your healthcare provider will first ask you about your symptoms and medical history. Other diagnostic tests include the following:

§  Blood tests. Blood tests are done to check the level of specific antibodies in your blood. In celiac disease, there are specific antibodies that will be elevated. It is important to remain on a gluten-rich diet (or your normal diet) when this blood test is performed. Otherwise, the antibody levels may become undetectable after a gluten-free diet is started.^1,2,7  Other blood tests may also be done to evaluate for deficiencies in iron, folate, calcium, and vitamin D.

§  Small intestinal biopsy. A small intestinal biopsy is performed when an individual tests positive for the specific antibodies in their blood test. A small sample of tissue will be removed from the small intestines by means of a small, flexible tube inserted through the mouth. The sample of tissue will then be examined under the microscope to look for changes characteristic of celiac disease in the small intestine tissue.^1,2,7

How is celiac disease treated?

Implementation of a gluten-free diet

Treatment of celiac disease requires implementation of a gluten-free diet where products containing wheat, barley, and rye are removed from the diet for life to avoid exposure to dietary gluten.^1,2 Approximately 70% of individuals experience improvement in their symptoms within 2 weeks of starting a gluten-free diet.⁹ The Table below lists examples of gluten-free foods.¹⁰

Table. List of gluten-free foods.¹⁰

Grains, flours and other starch-containing food		Other foods
Beans/ bean flours Buckwheat Corn/ corn flours Flaxseed Legumes Millet Nuts/ nut flours	Potatoes, potato starch/ flour Quinoa Rice Soy Tapioca/ tapioca starch Wild rice	Fruits Vegetables Meat and poultry Fish and seafood Dairy products

The complete elimination of gluten from the diet may be difficult as many processed foods use wheat in their manufacture. Thus, working with a dietitian can be beneficial to help find out about places to purchase gluten-free foods, cooking methods, and lifestyle resources to maintain a balanced, gluten-free diet. Individuals are encouraged to read labels on processed foods with care to determine if the food product contains wheat, barley, or rye.⁷

Although there is evidence that celiac patients can tolerate moderate quantities of oats (about 50 g per day), oats are frequently contaminated with wheat during their manufacture.⁶  Thus, it is recommended for patients newly diagnosed with celiac disease to avoid oats until symptoms resolve through a gluten-free diet. After symptoms have been controlled, up to 2 oz of oats from a reliable, uncontaminated source can be eaten daily and continued if symptoms do not return.²

Distilled alcoholic beverages such as wines are gluten-free unless gluten-containing flavorings are added after production. It is important to note that malt beverages such as beer, lager, ale, and stouts are not considered gluten-free and should be avoided.^2,7

Avoidance of dairy products

Some patients with untreated celiac disease may find that they are unable to tolerate dairy products when they are first diagnosed with the disease.¹²  The lactase enzyme, which is required to break down lactose in dairy products, is produced by cells that line the small intestine. In celiac disease, the production of the lactase enzyme is decreased due to the damage to the lining of the small intestine, resulting in lactose deficiency.²  Patients may choose lactose-reduced or lactose-free products if their symptoms are worsened by dairy products. Dairy products can be reintroduced after 3 to 6 months of a gluten-free diet when the lining of small intestine heals.

Dietary supplements

Patients with vitamin malabsorption may also receive a multivitamin preparation and appropriate supplements to correct nutritional deficiencies, including iron, folate, B vitamins, copper, and zinc. Other dietary supplements may include calcium and vitamin D for those individuals with hypocalcemia (low calcium) and osteopenic bone disease to prevent further bone loss.²

Gluten in medications

Inactive ingredients used as binders for medication pills or tablets may sometimes include starches or starch derivatives that contain gluten. In other cases, medications may come into contact with gluten during the manufacturing process. It is thus important for patients with celiac disease to be vigilant in checking the content of their medications with their pharmacist prior to taking them.¹¹ A helpful online resource is the website: http://www.glutenfreedrugs.com/, which is maintained by a clinical pharmacist and contains a list of medications that are gluten-free.¹²

Complications of celiac disease

It is important for patients with celiac disease to maintain a gluten-free diet for life to avoid complications of the disease.² Complications of celiac disease can include¹³:

§  Malnutrition

§  Nonresponsive celiac disease, where patients continue to experience symptoms despite a gluten-free diet, commonly due to unintentional ingestion of food contaminated with gluten.

§  Dermatitis herpetiformis, a skin condition where patient has very itchy bumps and blisters that look similar to those caused by the herpes virus. These bumps and blisters usually go away gradually after gluten is removed from the diet.

Headache Pain—Causes and Treatment with Nonprescription Analgesics

Headache disorders can be disabling, and they are one of the most common pain conditions affecting people worldwide. Globally, two-thirds or more of all adults will experience some form of headache disorder in their lifetime.¹ Despite the debilitating nature of headache disorders, they are rarely life-threatening, and most cases can be self-managed with nonprescription medications.

What are the different types of headaches in adults?

Headache disorders can be broadly classified into primary or secondary based on their cause. Primary headache disorders account for the majority and are not associated with an underlying illness. Tension-type headache is the most common form of primary headache, followed by migraine headache with or without aura. A small minority of patients have cluster headaches. Headaches caused by an underlying disease, such as infection, stroke, or head injury, are known as secondary headaches.² Anyone with characteristics of a secondary headache should consult a physician to evaluate whether the underlying cause is serious.

Tension-type headache

Tension-type headache often occurs when a person is experiencing stress, anxiety, or emotional conflicts; hence, it is also commonly referred to as a stress headache.² The pain is usually mild to moderate and is often described as a pressure or tightness affecting both sides of the head. Some people with tension-type headaches experience light sensitivity or sound sensitivity during the headache episode.³ The role of stress in tension-type headache is not clear, although some researchers believe that stress aggravates the abnormal pain processes already present in those individuals with headaches.⁴

Migraine headache

Migraine headache occurs less commonly than tension-type headache and is typically characterized by a throbbing pain that can affect either one or both sides of the head. In contrast to tension-type headache, migraine pain tends to be more severe and is often aggravated by day-to-day physical activities. Migraine headache can cause nausea or vomiting and may make you more sensitive to light and sound. Approximately 1 in 4 people with migraines develop an aura prior to the onset of the headache.⁵ The aura can be as short as 5 minutes or as long as 60 minutes.³ Symptoms of aura include blind spots (scotomas), seeing zig-zag patterns, feeling a prickling sensation on the skin, and difficulty in recalling or speaking intended words or phrases.⁶ The exact cause of migraine is still not clear, but changes in nerves and blood vessels in the brain may play a role.³

Cluster headache

Cluster headache is an uncommon type of primary headache characterized by an excruciating one-sided pain that typically begins in or around the eye or along the temple.  The attacks occur in clusters of weeks to months, separated by periods of no headache that can last for months to years.³ Treatment of cluster headache requires the use of prescription medications, and a physician consult is advised. Several links are provided at the end of this article if you would like to find out more about cluster headaches.

Medication-overuse headache

Medication-overuse headache is a form of secondary headache that results from taking pain-relieving medications too frequently. This type of headache occurs almost daily or every other day. Most people with medication-overuse headaches start off with a history of episodic headaches that triggers frequent use of pain-relieving medication. They subsequently develop a medication-overuse headache, which manifests as either a new type of headache or a marked worsening of their pre-existing headache disorder.³ Non-prescription medications that may cause this type of headache include acetaminophen, caffeine, aspirin, and non-steroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen and naproxen.²

How are headache disorders evaluated and diagnosed by a physician?

In most cases, headache disorders are evaluated and diagnosed primarily on a thorough review of the headache history.⁷ Your physician or healthcare provider will ask you to describe, as completely as possible, the signs and symptoms experienced during the headache episode. Information that will help your provider in the evaluation of your headache disorder include the location of the pain, the type of pain, the frequency and duration of the headache episodes, and the presence of associated symptoms (such as nausea, nasal stuffiness, or light or sound sensitivity).

When should I seek medical attention for my headache symptoms?

Headaches are rarely symptoms of serious illness and most cases can be managed with non-prescription remedies. Occasionally, headache may be a sign of a more serious underlying medical condition (such as stroke, tumor, or infection) that will require prompt medical attention. Consult your physician if you experience any of the following “red flag” warning symptoms^7,8:

·       Headache that is sudden in onset or rapidly becomes severe should be treated as an emergency and you should seek medical attention immediately.

·       Headache that can be described as the “worst headache of your life”

·       Headache precipitated or worsened by exertion (e.g., coughing, sneezing, bending over)

·       A new onset of headache after age of 50 years

·       Headache accompanied by neck stiffness, fever, or confusion

·       Headache associated with trouble seeing, weakness, or numbness 

·       Headache that progressively worsens over weeks to months

In addition, if you have frequent headaches that require more than 2 to 3 doses per week of non-prescription pain-relieving medication, it is recommended to seek medical advice. This is because taking pain-relieving medications too often can potentially cause medication-overuse headache later. Your physician may prescribe a preventive therapy to help to reduce the frequency and severity of the headache.

What non-medication therapies can I use to self-manage my headache?

A lifestyle with a healthy diet, regular exercise and sleeping patterns, avoidance of excess caffeine and alcohol, smoking cessation, and stress reduction is beneficial for most patients with headaches.⁸ A headache diary may also be helpful. Write down when your headaches start, what you were doing at the time, how long the headaches lasted, and if anything provides relief. Keeping a headache diary can help to identify triggers and monitor the frequency, severity, and response of your headache to treatment.⁸ Irregular sleep patterns, stress, menstruation, skipping meals, or taking certain foods such as chocolate and alcohol have been identified as some of the triggers that precipitate migraine attacks.² Triggers differ from person to person; once you identify your triggers, you can modify these risk factors to reduce the frequency of your migraine attacks.

What are non-prescription medications that I can use to treat headaches?

Available non-prescription analgesics for the management of headache include acetaminophen and NSAIDs. Tension-type headaches tend to be mild and can be treated successfully with non-prescription medications in most cases. Non-prescription analgesics also have a role in the treatment of acute migraine attack for some people. Medications such as aspirin, ibuprofen, naproxen, or the combination of acetaminophen-aspirin-caffeine have been recommended as a first-line treatment for mild-to-moderate migraine attacks.⁹ Acetaminophen alone has also been found to be effective for treatment of mild-to-moderate migraine attacks.¹⁰ Regardless of the medication used, you should take an appropriate dose of pain-relieving medication early in the course of headache. It is also important to keep in mind that frequent use of non-prescription pain-relieving medications is not appropriate and indicate the need to consult a physician for evaluation of the headache.

Acetaminophen

Acetaminophen is effective in relieving mild to moderate pain. It has few side effects when taken as recommended. However, severe liver damage has been reported with the use of acetaminophen, particularly among people taking more than 4,000 mg in a day.¹¹ These people often took more than one drug containing acetaminophen. Because there are so many non-prescription and prescription products containing acetaminophen, it is important to be aware of which products contain acetaminophen to avoid accidental overdose. However, some people may be at higher risk of the adverse liver side effect of acetaminophen, even at the usual recommended doses. If you are unsure of what dose of acetaminophen to take, which products contain acetaminophen, or whether acetaminophen is safe for you, consult your pharmacist for advice.

 

Non-steroidal Anti-inflammatory Drugs

NSAIDs are a group of medications that are effective for relieving pain and reducing fever and inflammation. Several NSAIDs are available without a prescription, and these include aspirin, ibuprofen, and naproxen. NSAIDs are generally well-tolerated but side effects can occur. Common side effects that people report with NSAID use is stomach upset (dyspepsia) and heartburn. Taking NSAIDs with food, milk, or an antacid may help to reduce these gastric side effects.² Severe stomach bleeding is uncommon, but has been reported in people taking NSAIDs. If you are 60 years or older, have a history of stomach ulcers or bleeding problems, are taking a blood thinner or steroid medications, or are taking NSAIDs for a longer period of  time than recommended, you may be at a higher risk of severe stomach bleeding.¹² Consult your pharmacist to find out more about the dose, proper use, potential side effects, and drug interactions for NSAIDs before starting the medication.
