2011-07-14T23:25:00.001-07:00

Posted by Lisa Ding, Community Manager

Hi Bloggers!

For more than a decade now, the Blogger team has watched our community of users grow dramatically and have had the pleasure of seeing some truly amazing blogs along the way. Here on Buzz, in addition to keeping you updated on new features, we’re going to focus on engaging with our user community and connecting more readers to exceptional blogs.

On Buzz, you can be expecting a variety of new posts, such as:

A revolving showcase of funny, interesting, beautifully designed, creative, and just plain awesome blogs.
Guest posts from other successful Blogger users.
Re-shares of interesting posts from your blogs.
Personal posts from members of the Blogger Team, so you can get to know us better.

In the coming weeks, I’ll be asking you to submit quality blogs that you enjoy reading. Each week, I’ll post a sample of the best blogs I’ve found within a certain theme (food, design, sports, etc) or, that incorporate a recently-released feature. I encourage you all to nominate blogs that don’t necessarily have an established following, since we’d like to promote new bloggers who could benefit from more interactions with other bloggers and more readers. Also, we’ll be sure to credit the nominators, so you’ll be getting a readership boost, too!

Please say hello via comments, and tell the Blogger community a little about yourself. Also, look out for the first request for blog nominations coming soon.

Best,
Lisa

Update on Browser Support

2011-07-14T23:23:00.001-07:00

Posted by Brett Wiltshire, Product Operations

Our team has been thinking a lot recently about browser support, and wanted to make you aware of our new plan moving forward. For web applications like Blogger to continue to evolve at a rapid pace, our engineering team needs to make use of new capabilities available in modern browsers. For example, Dynamic Views, which we previewed in March, and Web Fonts both require advanced browsers that support HTML5. Older browsers just aren’t able to provide you with the same high-quality experience.

For this reason, starting next month Blogger.com will only support modern browsers. Beginning August 1st, we’ll support the current and prior major release of Chrome, Firefox, Internet Explorer and Safari on a rolling basis. Each time a new version is released, we’ll begin supporting the update and stop supporting the third-oldest version.

As of August 1st, we will discontinue support for the following browsers and their predecessors: Firefox 3.5, Internet Explorer 7, and Safari 3. In these older browsers you may have trouble using certain features in Blogger as well as many other Google Apps such as Gmail, Google Calendar, Google Talk, Google Docs and Google Sites.

So if it’s been a while since your last update, we encourage you to take advantage of the improved performance and security these modern browsers have to offer by installing the latest version of your preferred browser. There are many to choose from:

As the world moves more to the web, these new browsers are more than just a modern convenience, they are a necessity for what the future holds.

Whom do dentists often consider their most “difficult” patient

2011-07-14T23:21:00.000-07:00

Surveys repeatedly show that dentists often view the anxious patient as
heir most difficult challenge. Almost 80% of dentists report that they themselves
become anxious with an anxious patient. The ability to assess carefully a patient’s
emotional needs helps the clinician to improve his or her ability to deal effectively
with anxious patients. Furthermore, because anxious patients require more chair
ime for procedures, are more reactive to stimuli, and associate more sensations with pain, effective anxiety management yields more effective practice
management.

What behaviors on the dentist’s part do patients specify as reducing their anxiety

2011-07-14T23:19:00.003-07:00

• Explain procedures before starting.
• Give specific information during procedures.
• Instruct the patient to be calm.
• Verbally support the patient: give reassurance.
• Help the patient to redefine the experience to minimize threat.
• Give the patient some control over procedures and pain.
• Attempt to teach the patient to cope with distress.
• Provide distraction and tension relief.
• Attempt to build trust in the dentist.
• Show personal warmth to the patient.

36. Discuss behavioral methods that may help patients to cope with dental fears and related anxiety

2011-07-14T23:18:00.000-07:00

1. The first step for the dentist is to become knowledgeable of the patient
and his or her presenting needs. Interviewing skills cannot be overemphasized. A
trusting relationship is essential. As the clinical interview proceeds, fears are
usually reduced to coping levels.
2. Because a patient cannot be anxious and relaxed at the same moment,
teaching methods of relaxation may be helpful. Systematic relaxation allows the
patient to cope with the dental situation. Guided visualizations may be helpful to
achieve relaxation. Paced breathing also may be an aid to keeping patients
relaxed. Guiding the rate of inspiration and expiration allows a hyperventilating
patient to resume normal breathing, thus decreasing the anxiety level. A sample
relaxation script is included below.

What's Your Heart Disease Risk?

2011-01-05T08:50:00.000-08:00

High cholesterol, lifestyle choices, and other factors increase heart attack risk. Find out if you're likely to have a heart attack within the next 10 years.

Even though you don’t have a time machine, you do have the ability to calculate your 10-year heart illness risk. Decades of research have shown how heart illness risk factors such as high cholesterol & lifestyle choices like smoking cigarettes add up.

The National Cholesterol schooling Program (NCEP) has published a set of guidelines that is intended to help patients & doctors exactly predict heart illness risk. The greater your risk for heart illness within 10 years, the more aggressive you need to be with prevention. For example, the guidelines note that individuals who already have coronary heart illness or an equivalent health condition, such as diabetes, have a more than 20 percent risk of a heart event within 10 years. Add other risk factors, such as high cholesterol, advanced age, cigarette smoking, & a relatives history of early heart illness, & your total risk notches up.

The NCEP guidelines include charts that enable you to calculate a very specific risk score, based on your risk factors, age, & gender. For example, a 57-year-old bloke could use the charts to find out that they gets 7 points for age, 5 points for cholesterol over 280, 3 points for smoking cigarettes, & 1 point for his slightly high but treated hypertension. Adding all of them together, they has 16 points, or a 25 percent risk of a heart illness event within ten years.

The same approach is applied to diet — using the diet appendix in the guidelines, you can give yourself points for the categories of foods you eat regularly to find out whether you are eating a heart-healthy diet.

“We need to match the intensity of treatment that they recommend to any patient with that patient’s level of risk,” says Daniel Levy, MD, director of the Framingham Heart Study & professor of medicine at Boston University in Boston. This is because the changes you may must make all have some degree of risk & burden attached to them.

four times you have a lovely idea of your heart illness risk, you can make an informed decision about the steps you need to take to reduce that risk.

Cardiac Rehabilitation

2011-01-04T13:54:00.000-08:00

After you have a heart attack (also called a myocardial infarction, or MI), participation in a cardiac rehabilitation program can reduce your risk of having any more MIs, and even of dying.

"Cardiac rehabilitation" is a structured program aimed at helping you develop a heart-friendly lifestyle. Ideally, it will consist of three components: exercise, risk factor modification, and dealing with stress and depression.

Exercise Rehabilitation

Exercise may be the most important component of a cardiac rehabilitation program, because regular exercise not only directly improves your cardiovascular system, but it also helps you with weight control, improves your response to stress, and (many claim) helps you stick to your heart-healthy diet. The benefits of regular exercise after an MI are well documented. Studies show that those who participate in exercise rehabilitation achieve a significantly lower risk of mortality, and of having recurrent MIs.

While almost everyone can safely engage in exercise after an MI, deciding what's "safe" needs to be individualized. Developing a safe exercise program requires taking several factors into account - including your general physical condition, the extent of the heart attack you've had, whether you are still having angina, your weight, and the condition of your limbs and joints. Having you perform a stress test, usually on a treadmill, helps the exercise rehabilitation clinician assess all of these factors, and is normally an important part of creating an appropriate "exercise prescription" for you.

Once the initial assessment is made, your rehab clinician will work with you (and your doctor) to prescribe a safe exercise program. This prescription will include the appropriate type (walking, jogging, swimming, etc.), duration, frequency and intensity of exercise that will safely improve your heart health. Obviously, that prescription will take into account your personal preferences, and your personal constraints.

Most often after a heart attack, the first several exercise sessions will be conducted under medical supervision, possibly with cardiac monitoring. But after a few weeks, as your heart heals and your exercise capacity increases, you will begin following a home-based exercise program that, ideally, will last forever.

Lifestyle "Rehabilitation"

Most cardiac rehabilitation programs today include extensive educational sessions on modifying your cardiac risk factors, such as weight control, smoking cessation, and diet. It is important for you to attend these sessions and absorb as much information as you can. Now that you have survived your heart attack, your health depends on your taking control of those aspects of your life that can be controlled, and that will go a long way toward determining your long-term outcome.

Psychosocial "Rehabilitation"

It is quite common to go through a period of depression or anxiety after an MI. Unfortunately, these problems can not only keep you from engaging in the exercise rehabilitation and lifestyle modifications you need to become healthy, but can also directly worsen your cardiac health.

Many cardiac rehabilitation programs employ individuals who are trained to recognize and help you work through the psychosocial issues that may inhibit your recovery. If you need more intensive therapy, they can help make the appropriate referrals for you.

Causes and diagnosis of chest pain in young females

2011-01-04T13:47:00.001-08:00

Chest pain is one of the common complaints heard in medical OPDs as well as at the GP�s clinic. Chest pain causes a lot of anxiety in the patient as it is many a time related to �heart attack� or angina and people are quite aware of the serious consequences of the symptom. Anyone having a chest pain would first think of the heart and would like to know if he/she is having a �heart attack�.

However not all times is a chest pain necessarily originating from or caused by diseases of the heart. There are plenty of other structures in the thoracic cavity and a systematic approach is needed to arrive at the correct diagnosis or in other words to find out the �real culprit� causing the chest pain.
Of special importance is the issue of chest pain in women, as this group is less liable to get heart disease till menopause. Estrogen is said to confer a protective effect and prevents the development of atherosclerosis. Myocardial infarction or Coronary artery disease (CAD) is very rare in menstruating women. As menopause approaches and estrogen levels go down, the probability of development of CAD catches up with those in men.
Even then, there are lots of young to middle aged, menstruating women complaining of chest pain and quite distressed about it. Before I highlight the special features of this particular issue lets first review the differential diagnosis of chest pain.

Differential Diagnosis of Chest Pain

1. Angina Pectoris/Myocardial Infarction
2. Other Cardiovascular Causes

a. Possibly Ischemic Pain
1) Aortic Stenosis
2) Hypertrophic Cardiomyopathy
3) Severe Systemic Hypertension
4) Severe Right Ventricular Hypertension
5) Aortic Regurgitation
6) Severe Anemia/hypoxia
b. Non Ischemic in Origin
1) Aortic Dissection
2) Pericarditis
3) Mitral Valve Prolapse

3. Gastrointestinal

a. Esophageal Spasm
b. Esophageal Reflux
c. Esophageal Rupture
d. Peptic Ulcer Disease

4. Psychogenic

a. Anxiety
b. Depression
c. Cardiac Psychosis
d. Self Gain

5. Neuromusculoskeletal

a. Thoracic Outlet syndrome
b. Lesions of Cervical/Thoracic Spine
c. Costochondritis[Tietze�s Syndrome]
d. Herpes Zoster
e. Chest wall pain

6. Pulmonary

a. Pulmonary Embolus/Infarction
b. Pneumothorax
c. Pneumonia with pleural involvement

7. Pleurisy
As most patients are anxious of their chest pain being that of Heart origin, we shall first have a look at the features of Cardiac Pain.
