The symptoms of tuberculosis (tb), which is active might vary and depend on which part of the body is infected. Diagnosing tb just from its symptoms can be a difficult, as the symptoms are not for tb alone meaning the symptoms can be of other diseases as well. For the confirmation and diagnosis of tb one must get a test done for tb. However, the general symptoms of tb are tiredness, weakness, weight loss, loss of appetite, fever, chills and night sweats.

Symptoms of pulmonary tb
Pulmonary tb is the tb of lungs. The symptoms of this are bad cough, which might have lasted for more than 3 weeks, chest pain, blood or phlegm might occur on coughing.

Extrapulmonary tb
The tb of any body part other than pulmonary is called extrapulmonary tb. This type of tb does not affect the lungs with the exception being the extrapulmonary tb also known as pleural tb. General symptoms of extrapulmonary tb are same as general symptoms of pulmonary tb.

Symptoms of lymph node tb
Lymph node tb also known as lymphadenitis is basically the enlargement and the inflammation of the lymph nodes. This is a response to the infections especially in children. The symptoms of this might be painless slow growing lymph nodes. These swollen lymph nodes can be in the neck area, though they might also be present in the groin. Lymph node tb of the neck is also called as scrofula or tb adenitis.

Symptoms of skeletal (bone and joint) tb
The common and the first symptoms are pain and depend on the area of the joint or the bone affected. Often it is marked with the loss of movement and curving of the affected bones and joints. The affected area also weakens and is prone to fractures.

Spinal tb is also called as pott disease or tb spondylitis
The symptoms of this depend on the affected site and the stage of the disease. However, back pain is one of the earliest symptoms.

Symptoms of meningitis tb
The meningitis tb starts with classical symptoms of meningitis. It usually starts with symptoms of pains and aches, fever and vague and unwell feeling. These might last for 2-8 weeks and then the evident symptoms like headaches, seizures, vomiting and stiffness might occur.

Symptoms of Tuberculosis

Ringing in the ears, medically called Tinnitus, is a condition in which the individual hears a certain sound continuously in the ears.

The nature of this sound varies with different individuals. The sound may be whistling, buzzing or bell-like; it might be low or high; seeming to come from a far point or from inside of one's body.

Tinnitus in most cases is subjective where only the affected individual is able to hear the sounds. In some cases, the condition might also be objective wherein the doctor/examiner might be able to hear the sounds on examining.

Understanding the most common cause:

The process of sound waves travelling from the ear to the brain is facilitated by hair cells. When these hair cells are damaged, the brain does not receive signals which cause dysfunction in the activity of neurons. This dysfunctional neuron activity results in the illusion of sounds in the said individual. This illusion is referred to as Tinnitus.

Other causes that might result in Tinnitus are:

Damage around the hearing sections of the brain also might result in ringing sounds / tinnitus. Excessive noise might result into Tinnitus and if not prevented might even progress to hearing loss. There are also some drugs that may cause or worsen the condition.

When to seek help:

In the case of a sudden episode of Tinnitus, it may be associated with hearing loss. Such an episode should be followed by visiting the doctor immediately to prevent any further damage.

Sometimes, the ringing sound occurs rhythmically with your heart beat. It might be because of a pulsating blood vessel and/or because of a sudden hike in blood pressure. This condition would also be relatively easy to cure if reported immediately to the doctor.

If ringing sound occurs with a certain movement, it might be associated with stroke in some cases. In such incidents, conveying the exact symptoms and seeking help sooner would help in treating the underlying cause effectively.

With the first episode of Tinnitus, a regular medication that you intake should be shown to the doctor to rule out medication as the cause or to discontinue a certain medication if found to the causative agent.

Ringing In Ears - What Does it Mean and When to Seek Help

The shoulder is one of the most intricate joints in the body and given that it is subjected to a lot of lifting and movements, there are chances for it to tear or dislocate. The shoulder is a ball-and-socket joint with the socket in the shoulder, and the ball in the upper arm. The joint space between the two bones is surrounded by cartilage, and the space between the two is filled with fluid. Especially in athletes, due to forceful movement, this joint could get dislocated or the cartilage could tear.

The Bankart lesion is when there is a tear of the cartilage in the central anterior shoulder. This causes the cartilage to be damaged, allowing the humeral head to slip down from the socket. When the arm is extended down or to the side, it is commonly dislocated. This can happen posteriorly also, but this movement and so the injury is less likely than an anterior dislocation. If there is also a fracture of the shoulder bone with this dislocation, then it is known as bony or osseous Bankart lesion.

Causes: Bankart lesions can be acute or chronic. Acute is when there is sudden dislocation due to sports activity or accidents. Repetitive use of the shoulder can also lead to chronic Bankart lesions. This is usually seen in sportspersons like swimmers, tennis players, and weightlifters.

Signs and Symptoms:

Pain: The most common symptom with Bankart is shoulder pain that restricts any kind of movement. One may find it difficult pick up things or lifting your hands and in some cases, it is difficult to even sit straight.
Weakness: The shoulder feels weak and one is unable to perform normal activities
Instability: One may lose the grip and strength.
Limited movement: The range of motion of the shoulder may be reduced compared to before the injury.
Crackling: The damage to the fibrous cartilage produces a crackling sound, which can be heard during the movement of the shoulder.
Diagnosis: A combination of symptoms, physical examination, X-ray, and MRI can help in confirming the diagnosis.

The course of treatment depends on the cause and condition of the patient. An exercise regimen is prescribed as the first step in the treatment process. If there is inadequate progress, or if the pain seems to be recurrent, open or closed shoulder surgery may be recommended to include the following:

Arthroscopy (closed surgery) to repair the cartilage damage
Ligament re-attachment
Bone reshaping
Cartilage build up and reshaping
Ligament repair to improve stability
Any of these shoulder surgeries would be followed up with measures to reduce further injury. It is therefore advised to visit a doctor in case of any such discomfort as he/she will be able to find out the severity of the situation and devise a treatment plan accordingly.

Bankart's Lesion - What Exactly Is It?

There are many common measures people take to improve their eyesight or to improve their vision, including wearing glasses, lenses, and many more. Here are some effective exercises, which can prove to be highly beneficial to improve your eye health:

1. Stretching
This is the most common and also one of the easiest to do. It requires you to just look up, hold for two seconds, look down, hold for two seconds and then repeat this procedure for each corner of your eye, which means top-left, top-right, bottom-left and bottom-right corners.

2. Flexing
This is simply rotating your eyes in circles. Roll your eyes in the clockwise direction for one minute and then roll your eyes in the anticlockwise direction for one minute.

3. Focus switching
This particular eye exercise is probably the most useful one to improve eye health. In this eye exercise, you have to hold something at a reading distance and cover the other eye. You then have to find something that is at least twenty feet away and trace its shape with one eye closed. With one eye closed, trace more shapes, which are twenty feet away.

4. Palming
This exercise is also very simple to perform. All you have to do is cover your eyes with your palms. Once you have done this, just wait and see that there are no bright flashes of light. If you see that there is a bright flash of light, just wait till they go. This is used primarily to distress the eyes.

5. Deep blinking
This is also an incredibly useful exercise for distance vision. What you have to do is to place some large letters are at a fair distance and then sit on a chair. You have to then close your eyes and tighten all your muscles for 5 seconds. After 5 seconds are over, you have to open your eyes and then you have to see the letters for a second or two. The more number of times you do this, the more clearly you will be able to see the letters after reopening your eyes.

However, these eye exercises are not universally accepted by all doctors.

Exercises to Improve Eye Health

While some scars are negligible, others can mar your beauty. With cosmetic surgery, today, it is easy to remove scars and make them less prominent. Scar revision surgery can range from invasive procedures, such as scar excision to non invasive procedures like cryotherapy, laser therapy and topical silicone therapy. However, none of these have perfect results. The main aim of scar revision surgery is to make the scars blend in as much as possible with the surrounding skin in terms of colour, texture and elevation.

Picking a scar revision procedure is a matter of weighing the pros and cons of each type of procedure and the cause for dissatisfaction: 
1. Functional limitations of the scar and likelihood of functional impairment after surgery
2. Patient's expectations
3. Location of the scar
4. Quality of skin type and surrounding tissue

Scars are formed due to a number of reasons, such as acne, cuts, burns, surgery and infection in a wound. Scars created by an overproduction of collagen are the most difficult to treat. In most cases, a patient requires multiple surgeries for scar revision.

Some of these surgeries are:
1. Surgical Excision: This procedure is usually performed on large scars that do not respond to medication. Here the surgeon shaves and cuts down scar tissue to minimize the size of the scar.
2. Laser Surgery: This is used to smoothen the scars with raised or uneven surfaces. It involves the removal of the top layer of skin and tightening of the layer below it.
3. Z plasty and W plasty: These surgical treatments aim to reduce the visibility of the scar by repositioning them along the natural lines and creases of the skin. All topics that sent after editing should be considered as approved.

All About Scar Revision Surgery

Osteoporosis is a disease that affects the bones of a patient. This is most commonly found in women, especially in those women who are close to or going through, menopause. Hormonal changes around this period in a woman's life usually lead to various changes in her body. One of these changes include loss of bone tissue which can leave the patient with brittle and weak bones, a condition that is also known as osteoporosis. This condition literally imbibes the word porous, meaning hollow bones. It is born from an acute deficiency of calcium and vitamin D. The DEXA Scan or bone density test, also known as the Dual Energy X-ray Absorptiometry Scan, is one of the most effective tests that can help you in detecting this kind of damage or thinning bones. Here's why.

    Fractures: The DEXA Scan is an important one because it sends low energy beam to areas like your joints and tissues to show how susceptible you are to fractures. It does so by measuring the strength of the tissues as well as the bones to see how brittle they may be.
    Other Ailments: Measuring the thinning of your bones can also point to the presence of other ailments that may have gone unnoticed or undetected, earlier. These can include kidney disease, hyperparathyroidism which happens due to overactive secretions of the said gland, as well as liver disease due a malfunctioning liver, intestinal disease and various disorders in the intestinal tract, and a serious vitamin D deficiency. With this scan, you can get an insight into the other parts of the body affected by the bone density and whether or not they are functioning properly.
    Estrogen: Simply checking the estrogen levels cannot ascertain whether or not you have osteoporosis, as a high estrogen level can be credited to a particularly heavy period cycle. It does not show the bone health the way a DEXA Scan does.
    Easy and Standardised: This method of scanning usually happens with the help of a mounted X ray machine type, hand held gadget which can be extended to conduct the scan. This is an easy and standardised method that releases low levels of radiation which also makes it a healthier option.
    Bone Density Scores: The T Scores and Z scores point towards the bone density and help in diagnosing the condition efficiently. With a systematic scoring system, it is a sure shot test for osteoporosis.

Osteoporosis is a serious condition. The first step in treating the same is to get a detailed scan like the DEXA scan done, so as to test the extent of the bone thinning to ensure that proper and timely treatment takes place.

Why is the DEXA scan important for osteoporosis patients?
