Vitiligo is a skin condition that causes loss of pigmentation of the skin. Melanocytes, the pigment cells, within the skin are destroyed. This causes these parts of the skin to lose color and turn pale. It might affect different parts of the body including the arms, legs, face and even genitalia. It can affect a person of any age, ethnicity or gender.

Causes
The exact cause of vitiligo is not definitively known. However, there are a number of risk factors that might contribute towards the condition. These include-

Autoimmune disorders- Vitiligo might be a result of an autoimmune disorder where the overactive immune system destroys the pigment cells of the skin.
Exposure to Chemicals- Exposure to certain chemicals can increase the risk of vitiligo by causing depigmentation.
Hereditary factors- There might be a genetic pre-disposition towards vitiligo. Though a person can exhibit symptoms of the condition at any age, it is most commonly found to manifest itself around the age of 20 years.
Symptoms
Vitiligo may start with a simple spot of pale skin but over time, this spot expands and turns paler until it is white in color. Irregular in shape, the edges of these spots may inflame and cause itchiness.

Treatment
The treatment of vitiligo will be determined by a number of factors such as the number and the extent of the white patches and where they are located. Vitiligo treatment includes cosmetic, medical and surgical methods.

Cosmetic Treatment- Cosmetic and skincare products such as sunscreens, dye or makeup can help relieve and hide signs of the condition.
Medical Treatment- Oral medication or medicated ointments may be prescribed to treat Vitiligo. Photochemotherapy which involves the use of PUVA rays to induce re-pigmentation may also be prescribed. If the condition has spread to a considerable extent then the physician might advise that the color from the remaining areas of the skin also be removed in order to match the affected areas.
Surgical Treatment- Surgical treatments are at times prescribed which involve skin grafting or tattooing. This is usually prescribed for those with small patches of affected areas.
With ongoing and extensive research being conducted on this skin condition, we will in the near future be able to both understand and treat it better.

Vitiligo - What Causes It and How Can It Be Treated?

HIV or the human immunodeficiency virus is a retroviral agent that causes the immune system of the body to weaken and lead to cause the acquired immune deficiency syndrome (AIDS). It is now treatable. Research is being conducted all over the world to formulate a targeted drug therapy for combating this life-threatening disease. No vaccine is available, which renders the world population highly susceptible to contract the infection.

HIV infection spreads from an infected person through contact with certain bodily fluids like blood and semen. Spread from one human being to another is called as transmission of HIV. Mother to child transmission, i.e. perinatal transmission is also common. Healthcare and hospital staff are at a great risk of occupational transmission. Other causes of transmission include sharing intravenous drug equipment, needle prick injury, organ transplantation and artificial insemination. Since vaccination and targeted drug therapy for remission are not available, prevention strategies play an important role in curbing the spread of infection.

A three-level prevention strategy is implemented for HIV infection.

Primary prevention- Activities that focus on prevention of uninfected people being infected.
Secondary prevention- Aimed at the provision of proper health care and behavioral facilities for HIV infected people like lifestyle changes, welfare rights advice, anti-discrimination measures.
Tertiary prevention- Aimed at minimizing the symptoms of an infected person; includes the provision of prophylactic drugs and complementary therapies.
The risk avoidance approach for transmission of HIV infection includes certain measures like practicing mutual monogamy & delayed sexual activity in the young population. Safe and appropriate use of syringes and needles is advised. Unnecessary blood transfusions should be completely avoided. Routine screening of HIV antibody should be done.

Risk reduction approach propagates the mandatory use of condoms during sexual intercourse. Sexually transmitted diseases should be treated to avoid the risk of transmitting infection. Sterile syringes should be used. If blood transfusion is necessary, then blood transfused should be evaluated well to meet the quality standards.

If HIV infection is suspected, anti-retroviral drug therapy should be started.
The only universally approved method of HIV transmission during sexual activity is the use of condoms.
Pharmaceutical methods for prevention and treatment include antibiotic drug therapy for sexually transmitted diseases, anti-retroviral drugs for infected individuals, pre and post-exposure prophylaxis and use of low space dead syringes.
Pre-exposure prophylaxis is advised for people who are at a higher than average risk of contracting the infection.
Drug therapy consisting of a combination of Tenofovir and Emtricitabine is prescribed, one per day.
Visit the physician at regular intervals and routine screening is done. Post-exposure prophylaxis is considered to be effective if the treatment is started within an hour of exposure, to effectively reduce the risk of seroconversion. A drug combination of Emtricitabine, Tenofovir and Raltegravir is given.
Social initiatives are undertaken to spread awareness and educate people regarding AIDS. Behavioral change and acceptance of social message is necessary to benefit from the social initiatives. Sex education, LGBT sex education and awareness, safe injection use programs, needle exchange programs, safe sex practice education are some social strategies implemented.
Prevention of transmission of HIV from mothers to children involves anti-retroviral drug therapy during pregnancy and post birth in the newborn child. Breastfeeding is avoided and bottle feeding is advised.

HIV Transmission - How Can It Be Prevented?

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?

Intercourse is meant to be a pleasurable and intimate experience. But it might become an unpleasant act if you are suffering from performance anxiety. When you are mentally occupied by questions such as "Do I look too fat?" or "Did I do that right?", sex stops being a gratifying experience.

Incessant anxiety over your ability or appearance can result in sex becoming nerve-wracking and stressful for you. It might even have you avoiding sex altogether. This psychological condition is termed as sexual performance anxiety.

Sex isn't only a physical reaction, there are emotions tied to it as well. If you are too stressed out and your mind is preoccupied, your body reflects your inner turmoil and you cannot get aroused.

Causes
The causes of sexual performance anxiety include:
1. Fear that you wouldn't be able to satisfy your partner and perform well sexually
2. Body image issues (Such as stressing about your weight)
3. Problems in your relationship
4. Men worry that their penis don't 'measure' up
5. Men might be concerned about taking too much time to orgasm, or about premature ejaculation
6. Women worry about not enjoying the experience or being unable to have an orgasm

Symptoms
Your mental state has a deep impact on your physical state. The effect of stress hormones norepinephrine and epinephrine can hinder your sexual performance. Symptoms of sexual performance anxiety include:

1. In men, blood vessels constrict due to the effect of stress hormones. This leads to reduced blood flow to the penis, thus making it difficult for the man to get an erection.

2. Often though it is less diagnosed in women, sexual performance anxiety leads to trouble in lubrication during sex. Lack of lubrication dims the desire to have sex.

Sexual performance anxiety is a vicious, inescapable cycle. Increased anxiety hampers you from having sex, making you think you won't be able to perform well, which causes even more anxiety.

Treatment
Consult a doctor you will be comfortable with discussing your problems. Sexual performance can be either treated by medication (if you have an underlying medical condition such as erectile dysfunction) or through therapy.

Talking to a therapist or counsellor about your problems can help you in several ways. You can learn to become more comfortable with yourself and your body. You can also understand your problems better, which can eliminate your anxiety.

Top 5 Reasons to Start Drinking Green

Ringworm is something which is quite unpleasant to have, to say the very least. However, there are just so many myths about it and if a person is to avoid it, debunking of these myths is something which is quite critical!

It comes in all forms! 

Ringworm can affect a person even when he or she thinks it is something else. As a matter of fact, a barber s itch is not a form of lice, as many people believe it to be. In actuality, it is a beard ringworm! The effect of this sort of ringworm can be quite irritating as what happens is that there is swelling of the face and sometimes even the person s neck. There are various parts of the body which can be affected by ringworm, apart from the face. These include the scalp, the feet and sometimes, even the groin area.

Anyone can get it! 

Many people are of the opinion that it is only children who are at risk to get ringworm. While it is true that children seem to have the propensity to be diagnosed with it, it is something which can affect people across all age groups. As a result, it is very important for a person to be aware of ringworm and what it looks like regardless of his or her age.

It is not caused by worms!

No matter how misleading its name may be, there is actually no worm as such which leads to the problem known as ringworm. In fact, it is caused by dermatophytes, which are a sort of fungi. The reason why it is called ringworm is due to the effect it has on the skin; it red spots on the skin in the pattern of rings, usually. However, if a person happens to get ringworm of the scalp, then he or she may not develop the rings which are associated with ringworm. In its stead, he or she may see that the scalp is getting progressively flaky. A flaky scalp is often seen due to the effects of dandruff. In fact, both conditions are often confused.

Antibiotics don t work!

When a person in a house has ringworm, it is generally thought that the problem is one which would go away as a result of following a course of treatment which involves some antibiotics. However, when it comes to ringworm, this is not the case. On account of the fact that it is a fungal infection, it is treated with anti-fungal medicines. Antibiotics kill bacteria. The fact that ringworm can be caught or given to a pet makes it something worth worrying about!
