Infantile haemangioma describes a benign (non-cancerous) condition affecting cutaneous blood vessels. It is also known as proliferative haemangioma because it is due to proliferating endothelial cells; these are the cells that line blood vessels Infantile haemangiomas are proliferative lesions that usually develop shortly after birth. They are distinct from  vascular malformations , which are usually present at birth and are less common Over 80% of infantile haemangiomas occur on the head and neck area. They grow to 80% of maximum size in the first three months and most stop growing at about 5 months. However, they may keep growing for up to 18 month. After that, they undergo regression or involution. This can take as long as 3-10 years. Nearly all flat infantile haemangiomas eventually involute and disappear without treatment. However, regression of bulky haemangiomas tends to be incomplete, and they may leave an irregular atrophic (thin) scar  in at least 50%...

E xposure to antidepressants during pregnancy does not impact a baby’s risk for autism or attention- deficit/hyperactivity disorder (ADHD) after birth. In an update to a 2014 study, researchers from Massachusetts General Hospital examined data from nearly 3000 children with autis m or  ADHD-related disorders  in order to eliminate or explain the risk for pregnant mothers on antidepressants. The prior study, which was published in Molecular Psychiatry, found that the increased risk for autism or ADHD was likely related to the severity of the mother’s depression, rather than antidepressant exposure. That study authors added that a mother’s depression was a known risk factor for several neuropsychiatric disorders. Using a similar cohort, the updated research found that the incidence of autism and ADHD increased among children whose mothers had taken antidepressants prior to becoming pregnant. However, antidepressant use during pregnancy was not linked t...

Psoriasis   is a chronic (long-lasting) disease. It develops when a person’s immune system sends faulty signals that tell skin cells to grow too quickly. New skin cells form in days rather than weeks. The body does not shed these excess skin cells. The skin cells pile up on the surface of the skin, causing patches of psoriasis to appear.  Psoriasis may look contagious, but it's not. You cannot get psoriasis from touching someone who has it. To get psoriasis, a person must inherit the genes that cause it. Types of psoriasis If you have psoriasis, you will have one or more of these types: (Plaque  (also called  psoriasis vulgaris Guttate (Inverse  (also called flexural psoriasis or intertriginous psoriasis Pustular (Erythrodermic  (also called exfoliative psoriasis Some people get more than one type. Sometimes a person gets one type of psoriasis, and then the type of psoriasis changes.
