China officially apologized for early slowness in dealing with the SARS epidemic.The viral outbreak was subsequently genetically traced to a colony of cave-dwelling horseshoe bats in Xiyang Yi Ethnic Township, Yunnan.The outbreak first came to the attention of the international medical community on 27 November 2002, when Canadas Global Public Health Intelligence Network (GPHIN), an electronic warning system that is part of the World Health Organizations Global Outbreak Alert and Response Network (GOARN), picked up reports of a "flu outbreak" in China through Internet media monitoring and analysis and sent them to the WHO. While GPHINs capability had recently been upgraded to enable Arabic, Chinese, English, French, Russian, and Spanish translation, the system was limited to English or French in presenting this information. Thus, while the first reports of an unusual outbreak were in Chinese, an English report was not generated until 21 January 2003. The first super-spreader was admitted to the Sun Yat-sen Memorial Hospital in Guangzhou on 31 January, which soon spread the disease to nearby hospitals.In early April 2003, after a prominent physician, Jiang Yanyong, pushed to report the danger to China, there appeared to be a change in official policy when SARS began to receive a much greater prominence in the official media. Some have directly attributed this to the death of an American teacher, James Earl Salisbury, in Hong Kong. It was around this same time that Jiang Yanyong made accusations regarding the undercounting of cases in Beijing military hospitals.
It has been proposed that the category of capillary malformations, also called vascular stains, be classified into seven major clinical types including nevus flammeus nuchae also known as nevus simplex, commonly known as stork bite or salmon patch.A capillary malformation is also a feature of the disorder macrocephaly-capillary malformation. Venous malformation
Venous malformations are typically ill-defined masses, coloured from pale to dark blue. They can affect any tissue in the body. The mass is soft, and easily compressed, and their blue colouring is due to the dilated anomalous involved veins. They are most commonly found in the head and neck. Venous malformations can often extend deeper from their surface appearance, reaching underlying muscle or bone. In the neck they may extend into the lining of the mouth cavity or into the salivary glands.A severe venous malformation can involve the lymph vessels as a lymphaticovenous malformation. Lymphatic malformation
Lymphatic malformations are congenital, developing from badly-formed lymphatic vessels in early embryonic development. Abnormal development of the lymph vessels results in their failure to connect and drain into the venous system.These lymph vessels can become blocked due to the collection of lymph which forms a cyst as a mass, and are known as lymphangiomas. They can be macrocystic, microcystic, or a combination of the two. Macrocystic have cysts greater than 2 cubic centimetres (0.12 cu in), and microcystic lymphangiomas have cysts that are smaller than 2 cubic centimetres (0.12 cu in). A macrocystic lymphangioma is also known as a cystic hygroma.
