A succession beginning in a dry area is known as xerosere. Xerosere is initiated on bare area like rocky lands, sand or stony lands and is characterised by extreme deficiency of water in soil. It also shows a few stages of development.
Another common query is “What is xerosis?”.
Xerosis is the medical name for dry skin. It comes from Greek: ‘xero’ means ‘dry’ and ‘osis’ means ‘disease’ or ‘medical disorder’. Xerosis is caused by a lack of moisture in the skin, which may be the result of ageing (senile Xerosis) or due to underlying diseases such as Diabetes.
I discovered this is a type of xerosere originating on bare rock surfaces. The original substratum is deficient in water and lacks any organic matter, having only minerals in disintegrated unweathered state.
How is xerosis treated?
The tendency toward dry skin tends to be inherited and is more common in families with a history of atopy. Low humidity, usually related to dry heat during the winter months, is an aggravating factor. Treatment of xerosis is aimed at rehydrating the stratum corneum. Emollients containing urea or alpha-hydroxy acids are particularly.
What is xerosis cutis?
Xerosis cutis is the medical term for abnormally dry skin. This name comes from the Greek word “xero,” which means dry. Dry skin is common, especially in older adults. It’s usually a minor and temporary problem, but it may cause discomfort. Your skin needs moisture to stay smooth. As you age, retaining moisture in the skin becomes more difficult.
Then, what is Xerostomia or dry mouth?
Dry mouth, or xerostomia, is the sensation you may feel when you don’t have enough saliva (spit). Saliva is the fluid produced by the salivary glands in your mouth. Dry mouth is a symptom of a condition, not a condition itself.
A less severe form of xerosis is xeroderma or normal dry skin. While xerosis is often a temporary condition that leaves the skin looking scaly, it can also cause discomfort, itchiness, and inflammation. If left untreated, this condition can cause breaks or cracks in the skin and lead to bacterial infection.
What is the treatment for xerostomia?
For sialolithiasis, removal of the stone and treating the abnormality in formation of saliva can help resolve xerostomia. Diabetes can be treated by managing hyperglycemia and reducing the blood sugar levels allows the body to attain a normal degree of serum osmolality.
What is the pathophysiology of xerostomia?
In amyloidosis, amyloid deposits in the salivary glands result in development of xerostomia. HIV-salivary gland disease occurs in some individuals infected with HIV, mainly in children. This disease results in enlargement of the parotid glands and, occasionally, the submandibular glands, resulting in xerostomia.
Is xerostomia from radiation treatment permanent?
The degree of permanent xerostomia depends on the volume of salivary gland exposed to radiation and the radiation dose. When the total radiation dose exceeds 5,200 c. Gy, salivary flow is reduced, and little or no saliva is expressible from the salivary ducts. These changes are typically permanent.
Which succession occur in dry condition?
The succession occur in dry condition is called Xerosere (xerarch). It undergoes following stages.
