Wounds and bruises are both injuries. However, they differ widely in terms of the causing factors, the nature of the injury, the pain they cause and the kind of treatment they require. The following are a few of the myriad ways in which the two injuries differ from each other:

1. A wound causes quick damage - the skin tissue is cut or punctured while a bruise (also called a closed wound) is where the skin is not torn. 

2. A wound is usually caused by a sharp object but bruises are the results of blunt force or trauma.

3. A wound almost certainly bleeds due to ruptured tissue and blood vessels. Blunt injury also damages the blood capillaries of the skin and causes blood to accumulate under the skin tissue, creating a dark patch of skin. Blood vessels can also break due to lifting of heavy objects or overexertion of muscles.

4. A wound carries the risk of infection because the skin is open but a bruise does not get infected.

5. A wound has a burning or stinging sensation but a bruise is characterized by swelling and a blunt throbbing pain.

6. A wound can be healed by antiseptic and antibiotic medication. Large wounds need to be closed by stitching them up to avoid severe infection. On the other hand, a bruise usually heals by itself. A cold compress and pain killers may be used to ease discomfort. Heat can be applied to the injured spot to normalize the blood flow and dissolve the blood clot.

7. A wound can lead to complications like bacterial infections or the healing might be delayed by chronic diseases like diabetes. In case of a bruise, it usually does not cause complications but if there's a blunt injury to sensitive areas like the head, the tailbone or the eyes, medical attention is advised.

8. Wounds and bruises can also be differentiated on the basis of their subtypes. The different types of wounds are:

a. Incision (sharp objects cutting the dermis layer of skin)
b. Abrasion (the epithelial tissue is scraped off)
c. Avulsion (a body structure is torn off)
d. Penetration (a sharp object causes an entry and an exit wound)
e. Puncture (only an entry wound caused by a sharp object)

The different types of bruises are:
a. Hematoma (blood pools under the skin)
b. Purpura (tiny spots of blood on the inside of the mouth)
c. Contusion (similar to hematoma and caused by external trauma)
d. Crush injury (caused due to a large amount of force on the body part for a long time)

Wounds VS Bruises

Tuberculosis is an opportunistic infection caused by the bacteria Mycobacterium tuberculosis. The infections occurring in people with weak immunity as compared to the people with a healthy immune system are called as opportunistic infections. As, HIV enters the human body, it replicates and weakens the immune system which in turn increases the risk of contracting Tuberculosis in people already suffering from HIV infection.

An HIV and Tuberculosis co-infection occurs when an individual has both, the HIV infection and an either latent or active TB disease simultaneously.  Each disease acts in speeding up the progress of the other, when HIV and TB infection is present together in the body. HIV infection speeds up the progression from latent to active Tuberculosis, Mycobacterium tuberculosis also accelerates the progression of replication and spread of the HIV infection.

HIV infection and Tuberculosis are totally different type of infectious diseases. HIV is a viral infection and TB is a bacterial one. An HIV infected person will not contract TB unless a contact happens with a TB infected person. TB spreads via droplet infection and is communicable. If a person lives in a country with a high prevalence rate of TB, an HIV patient is highly susceptible to contracting the infection. In the similar manner, a person suffering from TB gets infected with the HIV infection only through the blood and bodily fluids borne route, with unprotected sexual intercourse with an HIV infected individual being the most important cause.

Amongst all the other opportunistic infections, TB occurs at an earlier stage in the course of an HIV infection than most other opportunistic infections. Mortality rate in the co-infected patients is more than twice that of HIV infected individuals without a TB infection. Even if a patient is undergoing anti-retroviral therapy, the death rates remain high in co-infected individuals.The natural history and course of TB gets altered in people with an infected immune system. The damage to immunity due to HIV infection causes a drastic reduction in the pathogen killing capacity of the body. In such patients if there is no anti-retroviral treatment prescribed, then the latency period between the infection and progression of disease gets eliminated. 

An active phase of TB is observed in such individuals progressing within a short span of time, ranging from weeks to months, rather than years as it normally should be spanning. Risk of progression from a latent stage to an active stage of TB is around 10-15 times greater in an HIV infected individual as compared to the non-infected person. Such individuals also communicate the disease more rapidly to others.Pulmonary tuberculosis in an HIV infected person can present similar symptoms like that of a classic TB disease. However, a co-infection can sometimes show less presenting TB symptoms, where even the chest X-ray scans can be observed to be normal. A  subclinical  phase of Tb in co-infected patients can cause delay in the diagnosis of the symptoms and subsequently affect the prognosis due to lack of timely treatment.

Social stigma and discrimination has caused an obstacle in provision of adequate treatment for people with HIV. Proper counseling  and initiatives taken to provide indiscriminate care can aid in identification of co-infection and earlier stages. Anti-retroviral treatment teamed up with anti-tubercular drug regimen is prescribed and a successful treatment for drug sensitive cases of TB can be provided with medications for 6-8 months.

How HIV & TB  Are Related?

You may think that it is just a harmless drink or two at the end of the day to help you relax. it's just a few drinks when you get together with friends. or it's just that you need to get rid of the office stress. We all need to catch a break sometimes, which makes our favorite brand of drink our best friend. Trouble starts when 'a drink or two' moves to a level where you can't hold the drink anymore. It affects your ability to think straight and take decisions that you may regret in retrospect. Alcoholism not only has serious health consequences but also can ruin your life and relationships. Don't tread down the path of self destruction, or this is what you'll find:
1.        Conflict: It is not a coincidence that fights are common when one or both partners are caught up with alcohol abuse. It is said that if there is too much alcohol in your system, it hampers with your ability to make rational decisions. It allows you to become inconsiderate about others, and give more importance your addiction over their requirements. It, to an extent, numbs you to what others feel, and makes you drink even more.
2.        Financial loss: Alcohol costs money. And the more you spend to keep up with your addiction, the more money flows out of your monthly household expenses, monthly savings and retirement plans. And this money literally goes down the drain.

At the worst, you'll lose your job and end up with no work and no money to support your addiction.
3.        Accident prone: In 2014, 9,967 people died in drunk driving crashes - one every 53 minutes. This may sound only like a statistic to you - until you speak to the families who lost their loved ones or have to see them suffer through loss of limbs or brain function to bear lifelong suffering. And as far as you are concerned, you may end up seeing the wrong end of a prison. Such things have a profound impact on your relationship - many of which fail to last through the ordeal. 
4.        Infidelity: You've seen it a thousand times in movies - which actually might get reflected in reality, if you wake up next to someone whose name you don't know. 
5.        Infertility: Alcohols and babies don't mix. Too much alcohol intake can stop women from making and keeping a baby. 
6.        Divorce: An alcoholic husband or wife is a valid ground of mental trauma applicable in a divorce. 

6 Ways How Alcohol Abuse Can Ruin Your Relationship

Alzheimer s disease is a neurological, irreversible, progressive brain disorder. It is a chronic neurodegenerative dementia that causes the death of brain cells, causing memory loss and cognitive decline. It affects a person s thinking and behavior. The symptoms develop slowly and get worse as time passes.

Causes:
As it is a kind of dementia, Alzheimer s is caused by the death of brain cells. Over a course of time, brain cells die progressively and at the end, the tissue is left with fewer nerve cells and connections. As a result, the total brain size shrinks. Tiny inclusions called plaques and tangles can be seen in the postmortem. These cannot be seen or tested in a living Alzheimer s affected brain. These plaques are given the name  amyloid plaques  because they are found among the dying cells of the brain when a protein called beta-amyloid builds. The tangles stay in the neurons; they are formed from a protein called tau.

There are several reasons behind all this, some of which are listed below-

Anti-anxiety medications
Hitting on the head too many times
Regularly sleep-deprived
Loneliness
Diabetes in the brain
Old age
Genetic line
Down s syndrome
Cardiovascular diseases
Symptoms:
Alzheimer s disease damages the brain, so the clinical signs and symptoms begin to show very early. The symptoms are-

Memory loss
Agitation and mood swings
Poor judgment
The trouble with money calculations
Difficulty doing familiar tasks
Trouble in planning or solving a problem
Confusion with time and place
Difficulty in communicating
Loss of motivation
Inappropriate behavior
Aggressive personality
Childlike behavior
Preventing Alzheimer s disease:
Alzheimer s disease ultimately results in death. Even if there are treatments, they cannot fully cure it. So it s better to try to prevent it before it happens. Ways to prevent Alzheimer s disease are-

Eating more fruits and vegetables.
Eating berries every day.
Increasing omega-3 fatty acids.
Taking folic acid supplements.
Drinking grape juice or red wine with evening meal.
Doing the Mediterranean style diet.
Controlling the blood pressure.
Having strong social support.
Treatment of Alzheimer s disease:

Treatment of Alzheimer s disease is a long time process.
First of all, doctors perform a physical exam to check the overall neurological health. By this, they check muscle strength, reflexes, walking ability, sense of sight and hearing, coordination and balance.
Then comes the blood test to find the cause of confusion and memory loss by checking the thyroid disorder and vitamin deficiency.
Then they perform the neuropsychological test and check the mental status.
Then there are other tests, like MRI, CT, and PET.
After all this, drugs are given and a safe and supportive environment is created with proper exercise and nutrition.
Alzheimer s disease is undoubtedly the worst kind of disease. Hence, it is highly recommended to contact a doctor as soon as any symptom is noticed.

All About Alzheimer's Disease!

Asthma is a chronic lung condition wherein the air passage gets blocked or constricted due to the production of extra mucus. It is an age old condition which has been creating problems for people since a long time. Despite the seriousness of the condition, there are various myths people tend to believe about asthma.

Here are a few myths about asthma and the usage of inhalers:

Regular Usage of Inhalers is Addictive: This is a total myth. Using inhalers is not at all addictive, it is a necessity. Just because you use your inhaler regularly does not mean you are addicted to it.  Just like brushing your teeth every day isn't an addiction, taking your daily medicine from an inhaler isn't an addiction as well. Using an inhaler will just help you with your asthma condition.
Oral Medicine Gets Better Results than Inhalers: Absolutely not. In fact, it is proven that inhalers give better results than oral medications. Oral medication takes longer to act during a sudden asthma attack while inhalers deliver the drug directly to the lungs.
Inhalers Are Meant For Severe Asthma Cases: Well, this again is not true. Inhalers are used for treating asthma. Period. Asthma is a condition where your lungs inflame which is best cured with steroids, and the easiest way to have steroids administered to you is through the inhalation method. When you use the inhalers, the steroids are delivered directly to your lungs. They also have a minimum number of side effects when administered through inhalers.
Asthma is Curable: You might tend to think that asthma can be cured with the help of proper medications. You might think that asthma is not a constant condition. But it is not what you think. The symptoms of asthma might not be present all the time but that doesn't mean you do not have asthma. Asthma is a long-term condition where the airways swell up causing you to suffer from breathlessness. If you suddenly stop taking your daily medicines because the symptoms have not surfaced, then it will take you a long time before you will be able to totally recover from the next attack you suffer from.
If you have asthma, remember to take your medicines daily and timely. 

Debunking Asthma Myths

Diabetes might not be the end of the road for you. While it is a chronic disorder, there are a number of steps you can take to minimize its effects. Before that you should know what diabetes is and its various types.

What is diabetes?

Diabetes is a metabolic disorder where the sugar in your blood is not metabolized by the body. This leads to a situation wherein sugar accumulates in your blood; this condition is known as high blood sugar. Now, this can happen in two ways:

Type 1 Diabetes: In this type, the beta cells of the pancreas that produce insulin (the hormone that metabolizes sugar) are destroyed by the immune system of the body. This leads to a reduction in insulin levels, causing blood sugar to shoot up.

Type 2 Diabetes: Type 2 diabetes is a condition wherein the body cannot effectively utilize the insulin to metabolize sugar. This again leads to the accumulation of sugar in the blood.

Apart from these two types, there is a third type that is known as  gestational diabetes . Gestational diabetes occurs during pregnancy wherein the body produces hormones that inhibit insulin.

Now that you know the various types of diabetes, it is time to focus on preventive measures. The various tips for a high blood sugar level are:



Steer Clear of Sugar: Think of sugar as your enemy, as it is something that you have to stay away from. Sugar will only add to the high blood sugar content that you are already diagnosed with.

Welcome whole grains with open arms: Refined grains are a big no; that means no more of those delicious white bread sandwiches. Instead, opt for whole grains such as brown bread, brown rice and oats. Refined grains come under simple carbohydrates that cause your blood sugar levels to shoot up.

Avoid overconsumption of fruits: While fruits are healthy, they do contain fructose which is again, a form of sugar. So, yes eat them but limit their consumption to one serving a day.

High time you realize nothing substitutes exercise: Regular exercise can help you burn calories and also keep your blood sugar levels low. It allows you to maintain healthy weight levels and improves your overall wellbeing.

Take no stress: Stress has been shown to increase blood sugar, so if you are feeling stressed and can t seem to get out of with, take steps to deal with it. Practice relaxation techniques such as meditation that can help you reduce stress and improve focus.

If you wish to discuss about any specific problem, you can consult a doctor and ask a free question.
