Nasal Polyps are soft, tender, and non-cancerous growth inside the nasal cavity. These hang from the nose lining (usually both nostrils) like tear drops resulting in a running nose, loss of smell, decreased taste, etc. The polyps may vary in size and can be yellowish or pink in appearance. Large polyps can cause breathing difficulties and affect the patients smelling power. They block sinus and cause infections. The disorder seems to affect more than 10 million people per year in India alone. Nasal polyps are common in men as compared to women and can arise at any stage. People suffering from asthma, sinus, and allergies are more likely to develop the disorder.

Necrotic tissue is a medical condition in which there are dead cells in your body organ. The death of the cells happens due to lack of oxygen and interrupted blood supply. It causes the cells to be acidic, releasing enzymes that break the cells. The malfunctioning of cells can make other body parts inactive. It can later result in puncture of the cell membrane. Ultimately, the cell walls will explode due to the collection of extra fluid. Necrotic tissue is the result of skin necrosis. Necrosis is a premature death of cells which occurs due to autolysis (self-digestion of cells after release of enzymes). These cells are a part of the living tissue inside the skin. Necrosis occurs due to external injury or trauma in a particular organ. Necrotic tissue is skin necrosis, in which many cells die in the same organ. It is considered to be a damaging health condition, as it can result in serious diseases like skin cancer. Each year there are more new cases of skin cancer than the combined incidence of cancers of the breast, prostate, lung, and colon. Over the past three decades, more people have had skin cancer than all other cancers.

Nephrolithiasis is a condition which occurs due to the formation of hard deposits of minerals and salts in a person’s kidneys. These deposits are also known as kidney stones. Kidney stones can disturb the functions of the kidneys, the urinary tract and the bladder. The stones can be passed out of the body along with urine and cause no permanent damage if they're detected at an early stage. However, they may get stuck in the urinary tract and lead to complications (urinary infections) if they are larger in size.

When your body starts to excrete too much protein in your urine, the condition is nephrotic syndrome. Kidneys filter the excess waste from our body and the damage to the clusters of the blood vessels of the kidney results in nephrotic syndrome. It is caused due to damage to the glomeruli, the structures in the kidneys responsible for filtering the blood. As a result of this damage, the protein in the blood leak into the urine and increases the excretion of protein(proteinuria). It is soon followed by a reduction in albumin levels in the blood. This condition may affect adults and children of both sexes. It is a disease specific to the kidneys, its glomerular inflammation is associated with the impaired kidney function.

Nerve injury is when a nerve stops transmission of signals from one side of the brain to the other, prevents muscles from working, and causes a loss of feeling in the area supplied by that nerve. There are three basic types of nerve injury. The first kind is where the nerve is bruised and does not work properly for a short period of time, but all the inner cables remain intact. This type of nerve injury recovers fully and leaves no deficit at all. The second kind is where the inner cables are damaged, but the outer layer remains intact. The third kind is where the nerve is divided, and both the outer layer and inner cables are divided. This type of injury requires the nerve to be repaired, if it is to recover.

Nystagmus is a condition of uncontrollable eye movements, that maybe side to side, up and down or in a circle. Due to unintentional eye movements, it is generally referred as ‘dancing eyes’. It usually arises in infancy, but can also be developed later in life. Once assumed incurable, now various drugs and treatments are available for nystagmus. Early diagnosis and treatment would prevent the risk of limited or reduced vision.
