The picture above is of a bruise with a mixture of colours, which is diffusing at the yellowing edges, indicating that this was probably inflicted several days before this photograph was taken. 1.

This term is used to describe very small 'pinpoint' (i. Their pathogenesis is poorly understood, but may relate to raised intra- capillary pressure due to an obstruction of venous return (subsequent to pressure applied to the upper chest or neck, for example), hypoxia, endothelial dysfunction (in sepsis) or a combination of these factors (Jaffe 1. Petechiae can also be caused by blunt trauma (Jaffe 1. Saukko and Knight 2.

The presence of petechiae has been reported in a wide variety of situations including; Although they appear to be a non- specific manifestation of capillary damage or dysfunction, their presence demands an explanation, and in particular prompts a careful examination of the anterior neck structures in order to exclude pressure having been applied to the neck.(See National Library of Medicine (USA) - image of petechial haemorrhages, and University of Toronto 'Anatomia' - anatomy of the larynx )2. Where an extravasation of blood arises within the deeper dermis, allowing extension of blood into subcutaneous tissues, the 'outline' of the briuse seen at the skin surface is usually 'blurred' or indistinct. If the bleeding occurs more superficially, however, the result is a so- called 'intradermal bruise', where the components of the bruise are more easily deliniated (punctiform, sharply defined and 'bright red in colour'). A 'negative image' of the profile of the impacting instrument is produced i. Bohnert et al 2. 00.

In these injuries, usually caused by an impact to the skin by an implement that has a surface consisting of 'grooves' or 'ridges', the outline of the implement may be 'retained'. The finding of a 'patterned' injury is of considerable forensic interest - careful documentation and photography of such a wound may allow subsequent matching of a putative injury- causing implement with the skin surface bruise (a form of 'tool mark' analysis utilising computer- enhanced photographic 'overlay' techniques).

The skin surface is indented and blood vessels at the edges are ruptured. Blood is squeezed out of any vessels along the point of contact, but the vessels remain relatively intact (particularly if the supporting tissues are lax).

When the impacting object is removed, blood flows back into the undamaged vessels, but leaks from the damaged ones. The resulting bruise is termed a ‘tramline bruise’ because it appears as a pale linear central area lined on either side by linear bruising(See a picture of tramline bruising)4.

Mongoloid - Wikipedia. Mongoloid[1][2] is a term used for all or some peoples indigenous to East Asia, Central Asia, Southeast Asia, North Asia, South Asia, the Arctic, the Americas, the Pacific Islands, and other lesser occurrences in other regions, but are the minority. Individuals within these populations often share certain associated phenotypic traits, such as epicanthic folds (skin folds covering the corners of the eyes), sinodonty (shovel tooth dental shape) and neoteny (retaining more juvenile physiological traits). The concept of Mongoloid races is historical referring to a grouping of human beings historically regarded as a biological taxon. It is today not widely used by anthropologists as its validity and usefulness in classification is considered highly questionable. Epicanthic folds and oblique palpebral fissures are common among Mongoloid individuals. Most exhibit the Mongolian spot from birth to about age four.[3][4] Mongoloids in general have straight, black hair and dark brown almond- shaped eyes, and have relatively flatter faces in comparison to caucasoid skull.[5]Traits more controversially ascribed to Mongoloids include high intelligence[6][7][8] and a stoic, taciturn, unaggressive demeanor.

The extent to which individual psychological makeup is a social construct, rather than a matter of biology, remains a matter of debate. See also the articles Race and intelligence and Model minority.)The term mongoloid was introduced by 1.
