Visual impairment is a decreased ability to see to a degree that causes disabilities or problems, not fixable by usual means, such as glasses. Loss of vision may be acquired and develop suddenly. It may affect one or both your eyes.

What Causes Loss of Vision/Disability?

Loss of vision and disability can result from the following  

Clouding of normally transparent eye structures

Abnormalities in the retina

Abnormalities in the nerves carrying visual signals to the brain from the eyes

Changes in vision may also occur due to conditions like glaucoma, macular degeneration and diabetic retinopathy. 

Can Psychological Rehabilitation Help Manage Visual Impairment?

Vision loss and disability often interfere with one s functional ability in everyday tasks. Sometimes, the disability may be so devastating that it affects a person s mental health and behaviour. Psychological Rehabilitation is designed to help such visually impaired people deal with disability or impairment. 

Psychological rehabilitation involves a wide range of methods that aims to restore functioning after loss of vision, just as physiotherapy restores functioning after an injury or stroke. The program allows patients to continue living independently and maintain their quality of life despite vision loss. 

Complete or partial loss of vision can jeopardize one s career   you may not be able to continue with your job due to the disability.  Many people suffer psychological and physical challenges, which force them to escape the outside world. Psychological rehabilitation helps in the following ways  

Helps individual understand and accept the disability, and find ways to cope with it

Motivates them in to keep trying

Cope with the pain and depression

Overcome feelings of fear or despair

Prevents the person from sinking into a state of self-pity, which may hinder recovery

Rehabilitation Psychology adopts a holistic and expansive approach to treat visual impairment. 




Loss of Vision & Disability - How Can Psychological Rehabilitation Help?

Photodynamic therapy or PDT is a relatively new and non-invasive treatment for non melanomaskin cancer. It is mostly used in cases where the cancer is superficial and has not spread too deep. PDT is used mostly to treat Actinic Keratoses on the face and scalp, Basal cell carcinomas, Bowen s disease, as well as other conditions such as head and neck, mouth, lung and gullet cancer.

How does it work?
This treatment involves the use of a drug known as photosensitize or a photosensitizing agent with a specific type of light. When the photosensitizing agents get exposed to a light of a specific wavelength, a form of oxygen is produced, which eliminates nearby cancer cells. Every photosensitizer gets activated by the special light. The wavelength of the light determines how much it can penetrate into the body.

Process of Photodynamic therapy
Skin cancer is cured by PDT in several steps. The first step involves the injection of a photosensitizer into the patient s bloodstream. The blood cells absorb the agent all over the body, but in the cancer cells, it stays for a longer duration. Within 72 hours after the injection is given, the skin is exposed to light. The photosensitizer agent present in the cancer affected cells absorbs the light. An active oxygen form gets produced, which kills the cancer cells.

Other than killing the cancer cells directly, PDT uses two other ways to destroy cancerous tumors. The blood vessels in the tumor are affected, which leads to its death. The immune system also gets charged up and activated for fighting the cancer cells.

The light used for PDT is usually in the form of a laser. LEDs are also used to treat tumors present on the surface of the skin. The primary photosensitizing agent used in PDT is called porfimer sodium or Photofrin.

PDT can be undertaken in the outpatient department in a hospital. After taking the treatment, you have to keep the cancer affected area of the skin dry and covered for 36 hours. The area should be treated with care while showering. In case of thick skin lesions, repeat treatments are required within 4 weeks.

When is PDT used for skin cancer
PDT can be undertaken instead of surgery for treating basal cell cancer, Bowen s disease and actinic keratosis. PDT is used in cases where surgeries are required. It is used to treat large skin cancers, which are not very deep and in the case when several cancers develop in an area. For many skin conditions, PDT is a better remedy than undergoing a surgery.

Advantages of PDT

    There are no long term side effects.
    The process is less invasive compared to surgery.
    A very short time is taken for this therapy to be undertaken.
    The process can be repeated several times in the same area.
    Very less scarring takes place in the affected area.
    The cost of this procedure is lesser than surgery.

Treating Skin Cancer with Photodynamic Therapy

Asthma is a condition that can flare up anytime; be it at your child's soccer practice or during the middle of the night. Whenever the condition sets in, it leads to your child struggling for breath. For a parent to witness this situation can be hard; but you should know the techniques to keep the situation under control.

Here are a few tips on how to manage the situation:

1. Find out the triggers in your home: Asthma is triggered due to substances that your child may be allergic to. Examples are cigarette smoke, fur of pets and dust. If possible, keep your child away from the known triggers so that the condition does not flare up again.

2. Keep records of the following: It is good to have an action plan ready for your child when the bouts of asthma strike. When you visit the doctor to discuss about your child's condition then make sure that you have these records at hand.

The triggers that caused the bout of asthma
How many times did your child have wheezing episodes?
The number of times your child has been admitted for the same reason
The medications that your child is currently taking, dosage and/or whether they have been changed
How often does he/she need medications if he/she has acute symptoms?
3. Knowledge of the test your child may require: Asthma control test is a type of test that allows parents and children to grade asthma symptoms without a doctor. A pulmonary function test is used to detect the capacity of the lungs and flow of air.

4. See how your child responds to the treatments: You should consider changing the treatments for your child if he/she has recurrent symptoms of asthma attack and require frequent visits to the Emergency Room even after taking medications for an extended duration.

5. Long term treatment plans require patience: Any asthma treatment plan requires patience as they might not immediately cure symptoms.

How to Manage if Your Child Is Suffering From Asthma

7 causes of heavy menstrual bleeding you must know about

Heavy menstrual bleeding, also known as Menorrhagia, refers to the state of abnormally heavy bleeding during periods. It's common for women at the premenopausal stage of their life to experience heavy bleeding during periods; but if you are not among them, heavy menstrual bleeding is a matter of severe concern.

If you normally lose a lot of blood during your periods or experience severe cramps that prevent you from leading your normal lifestyle, you must first identify the cause of it.

Here are some of the most common conditions that are responsible for causing Menorrhagia.

Disturbed hormonal balance: Menstruation involves the shedding of the lining of the uterus (endometrium), whose build-up is generally controlled by the balance between oestrogen and progesterone, the two significant hormones of your body. It sometimes happens that there is excess endometrium generation due to disturbed hormonal balance, which results in heavy menstrual bleeding.

Polyps: Sometimes heavy menstrual bleeding occurs due to the occurrence of uterine polyps, which are tiny growths appearing on the uterus lining. This condition is mostly prevalent among women of child-bearing age caused due to raised levels of hormones.

Intrauterine device (IUD): People who use birth control methods like intrauterine device or IUD are likely to experience certain side effects which include heavy menstrual bleeding. If the cause behind your menorrhagia is an IUD, you might need to remove it to get relief from the condition.

Pregnancy complications: If you experience your period later than usual and it is associated with excessive bleeding, it may be caused by a miscarriage. Moreover, you might also experience menorrhagia incase of an ectopic pregnancy, a condition when the fertilized egg is implanted within the fallopian tube in place of the uterus.

Uterine fibroids: Women of reproductive age may develop noncancerous (benign) tumours in the uterus known as uterine fibroids. These fibroids can be responsible for giving you periods lasting longer than usual accompanied with excessive bleeding.

Cancer: Though it is a rare case, sometimes the reason behind heavy menstrual bleeding may be uterine cancer, cervical cancer or ovarian cancer.

Medications: consumption of certain prescription drugs such as anticoagulants and anti-inflammatory medicines may lead to prolonged or excessive menstrual bleeding.





7 Causes of Heavy Menstrual Bleeding You Must Know About

Knee pain is one of the most common and painful ailments that can limit mobility. Injuries can result in cartilage or meniscal tears or sprains too. Obesity is another reason because of which knee pain is on the rise. Also, regular wear and tear of ligaments and tendons around the knees due to old age is another cause. These days, with reduced physical activities and sedentary lifestyles, the rate at which knees are wearing out has also become accelerated. Whatever the reason, a correct diagnosis followed by prompt treatment can help. Over the years, physiotherapy has been playing an important role in treating knee injuries. Whether to supplement the various drugs to reduce pain and inflammation or to avoid surgery, physiotherapy has helped many and its popularity is growing every day. Here are some ways that physiotherapy can help reduce pain.

Improve flexibility of tendons: The knee cap is an area where there are lot of tendons and ligaments, coordinating to enable movement. Careful exercising can ensure that the flexibility of tendons and ligaments is improved, thereby making your knee movement easier and less painful.
Improves blood supply: As we all know, proper movement requires good blood supply. Exercising with special focus on the knee ensures that blood supply is improved, and thereby the supporting ligaments and tendons function optimally.
Enhances the knee cap function: The knee cap is that portion which joins your thigh bone to your calf bones. This is prone to slip out of place, especially with arthritis and injuries. This can be painful and limit movement to a great degree. Focused exercises aimed at improving knee cap function will ensure that the knee cap has a wider range of function, and does not slip out of its socket easily.
Reduce rigidity: Once you start physiotherapy, you will feel your knees getting more flexible. The rigidity that had set in as a result of injuries and/or old age will also reduce over a period of time.
Slow down the wear and tear: When you start physiotherapy after knee damage, continuing the exercise routine, of course with expert guidance, can reduce the pace at which further damage might happen. A word of caution though. Be sure to consult an experienced physiotherapist before you begin. Exercising in a bad manner can do equal or more harm than the original injury or old age itself.

Knee Pain and Physiotherapy

Pulmonary hypertension mainly occurs due to narrowing of the arteries of the lungs as a result of which the flow of blood is restricted. In this kind of condition, blood fails to carry oxygen to your heart and thus your heart gets adversely affected. The blood pressure of your body will get increased to a great extent if this situation remains untreated, thus leading to bdreadful consequenses, specifically situation like heart failure, serious pulmonary diseases, blood clots in lungs and congenial heart defects, etc.

There are certain forms of pulmonary hypertension, which are serious in nature and worsen with time, so much so that they are even fatal at times. It also includes forms which are non curable in nature, however, in order to improve the quality of life, symptoms can be reduced with proper treatment. The treatment for pulmonary hypertension is often complex and it takes some time to find the most appropriate treatment and requires extensive follow-up care. Your doctor might also need to change your treatment if it's no longer effective. However, when pulmonary hypertension is caused by another condition, your doctor will treat the underlying cause whenever possible.

Common treatments for pulmonary hypertension:

Medications

1. Blood vessel dilators (vasodilators): vasodilators open narrowed blood vessels. They are one of the most commonly prescribed vasodilators for pulmonary hypertension is epoprostenol (flolan, veletri). The drawback to epoprostenol is that the effect lasts only for few minutes. This drug is continuously injected through an intravenous (iv) catheter via a small pump that you wear in a pack on your belt or shoulder.

2. Ventavis: another form of the drug, iloprost (ventavis), can be inhaled six to nine times a day through a nebulizer, a machine that vaporizes your medication. Because it's inhaled, it goes directly to the lungs.

3. Treprostinil (tyvaso, remodulin, orenitram): it is another form of the drug, which can be given four times a day and can be inhaled or can be taken as an oral medication and can also be administered through injection.

4. Endothelin receptor antagonists: these medications reverse the effect of endothelin, a substance in the walls of blood vessels that causes them to narrow. These drugs may improve your energy level and symptoms. However, these drugs shouldn't be taken if you're pregnant. Also, these drugs can damage your liver and you may need monthly liver monitoring.

6. Sildenafil and tadalafil: sildenafil (revatio, viagra) and tadalafil (cialis, adcirca) are sometimes used to treat pulmonary hypertension. These drugs work by opening the blood vessels in the lungs to allow blood to flow through more easily.

6. High-dose calcium channel blockers: these drugs help relax the muscles in the walls of your blood vessels. They include medications, such as amlodipine (norvasc), diltiazem (cardizem, tiazac, others) and nifedipine (procardia, others). Although calcium channel blockers can be effective, only a small number of people with pulmonary hypertension respond to them.

7. Soluble guanylate cyclase (sgc) stimulator: soluble guanylate cyclase (sgc) stimulators (adempas) interact with nitric oxide and help relax the pulmonary arteries and lower the pressure within the arteries. These medications should not be taken if you're pregnant. They can sometimes cause dizziness or nausea.

8. Anticoagulants: your doctor is likely to prescribe the anticoagulant warfarin (coumadin, jantoven) to help prevent the formation of blood clots within the small pulmonary arteries. Because anticoagulants prevent normal blood coagulation, they increase your risk of bleeding complications. Take warfarin exactly as prescribed, because warfarin can cause severe side effects if taken incorrectly. If you're taking warfarin, your doctor will ask you to have periodic blood tests to check how well the drug is working. Many other drugs, herbal supplements and foods can interact with warfarin, so be sure your doctor knows all of the medications you're taking.

9. Digoxin: digoxin (lanoxin) can help the heart beat stronger and pump more blood. It can help control the heart rate if you experience arrhythmias.

10. Diuretics: commonly known as water pills, these medications help eliminate excess fluid from your body. This reduces the amount of work your heart has to do. They may also be used to limit fluid buildup in your lungs.

11. Oxygen: your doctor might suggest that you sometimes breathe pure oxygen, a treatment known as oxygen therapy, to help treat pulmonary hypertension, especially if you live at a high altitude or have sleep apnea. Some people who have pulmonary hypertension eventually require continuous oxygen therapy.

Surgeries

1. Atrial septostomy: if medications don't control your pulmonary hypertension, this open heart surgery might be an option. In an atrial septostomy, a surgeon will create an opening between the upper left and right chambers of your heart (atria) to relieve the pressure on the right side of your heart.

2. Lung transplantation: in some cases, a lung or heart lung transplant might be an option, especially for younger people who have idiopathic pulmonary arterial hypertension.

Reducing complications

1. The complications need to be reduced by taking proper health care. Healthy diet needs to be taken regularly along with proper medications. Smoking should be stopped and exercising sessions should be attended daily without any fail

2. Overweight or obesity needs to be controlled properly for reducing the complications. Specialized caring strategies need to be maintained for avoiding severe kinds of health complications that are quite annoying.
