Psoriasis is a noncontagious noncurable common long term skin condition that causes rapid skin cell reproduction resulting in red, itchy, dry patches and thick silvery scales of thickened skin. The dry flakes and skin scales are thought to result from the rapid buildup of skin cells. Psoriasis commonly affects the skin of the elbows, knees, and scalp. Sometimes psoriasis may clear for years and stay in remission. Some have worsening of their symptoms in the colder winter months. Many show improvement in warmer climates, or with increased sunlight exposure. Patients with more severe psoriasis may have social embarrassment, job stress, emotional distress, and other personal issues because of the appearance of their skin.

Hay fever, also called allergic rhinitis, causes cold-like symptoms such as a runny nose, congestion, sneezing and sinus pressure. But unlike a cold, hay fever isn't caused by a virus ? it's caused by an allergic response to indoor or outdoor airborne allergens, such as pollen, dust mites or pet dander. Some people have hay fever year-round. For others, hay fever gets worse at certain times of the year, usually in the spring, summer or fall. One of the most common allergic conditions, hay fever affects about one in five people.

Achalasia Cardia is primarily a disease of esophagus in which lower end of esophagus (Lower Esophageal Sphincter-LES) does not relax properly in response to food intake and there is inappropriate and ineffective motility (Peristalsis) of the body of esophagus. This leads to impaired emptying of esophagus and gradual dilatation of this tubular structure. There is thickening of lower end along with increase in fibrous tissue in muscular layer of esophagus.

Barotrauma is damage to the middle ear caused by unequal air pressure on the two sides of the eardrum. Normally, the Eustachian tube, which connects the middle ear and the back of the nose, helps maintain equal pressure on both sides of the eardrum by allowing outside air to enter the middle ear. When outside air pressure changes suddenly?for example, during the ascent or descent of an airplane or a deep-sea dive air must move through the Eustachian tube to equalize the pressure in the middle ear. These fast changes in altitude cause air pressure changes and can trigger barotrauma.

Atopic dermatitis (AD) is an immune-mediated inflammation of the skin, often with a significant genetic component. Pruritus is the primary symptom. Skin lesions range from mild erythema to severe lichenification. Atopic dermatitis is IgE-mediated (extrinsic type, 70 to 80% of cases) or non-IgE-mediated (intrinsic type, 20 to 30% of cases).
