Petechiae on the face and conjunctiva (eyes) are unrelated to asphyxiation or hypoxia. [10] However, the presence of petechiae may be used by police investigators in determining whether strangulation has been part of an attack. The documentation of the presence of petechiae on a victim can help police investigators prove the case. [11]

In July 2013 the Italian San Raffaele Telethon Institute for Gene Therapy (HSR-TIGET) reported that three children with Wiskott–Aldrich syndrome showed significant improvement (improved platelet counts, immune functiona, and clinical symptoms) 20–30 months after being treated with a genetically modified lentivirus.

Petechiae What it looks like : “Petechiae is essentially blood leakage into the skin,” explains Dr. Lal. It looks like small red blotches or tiny, red pinpoint marks on the skin.
Purpura (/ ˈ p ɜːr p jʊər ə / [1]) is a condition of red or purple discolored spots on the skin that do not blanch on applying pressure. The spots are caused by bleeding underneath the skin secondary to platelet disorders, vascular disorders, coagulation disorders, or other causes. [2]
Traumatic asphyxia is characterized by cyanosis in the upper extremities, neck, and head as well as petechiae in the conjunctiva. Patients can also display jugular venous distention and facial edema. [3] Associated injuries include pulmonary contusion, myocardial contusion, hemo/pneumothorax, and broken ribs. [4] [5]
Petechiae – small pinpoint hematomas less than 3 mm in diameter Purpura (purple) – a bruise about 3–5 mm in diameter, generally round in shape Ecchymosis – subcutaneous extravasation of blood in a thin layer under the skin, i.e. bruising or "black and blue", over 1 cm in diameter [ 3 ]
Purpura fulminans is rare and most commonly occurs in babies and small children [25] but can also be a rare manifestation in adults when it is associated with severe infections. [26] For example, Meningococcal septicaemia is complicated by purpura fulminans in 10–20% of cases among children. [ 27 ]
