  • The sudden impact on the genitals causes an increase in intrathoracic pressure. In order for traumatic asphyxia to occur, a Valsalva maneuver is required when the traumatic force is applied.Exhalation against the closed glottis along with the traumatic event causes air that cannot escape from the thoracic cavity. Instead, the air causes increased venous back-pressure, which is transferred back to through the right atrium, to the superior vena cava and to the head and neck veins and capillaries.
  • Clinical signs include conjunctival petechiae, facial petechiae, cutaneous blue–purple discoloration and congestion of the face and neck, and seizures, confusion, and unconsciousness

  • The Colosseum is situated just east of the Roman Forum. Construction began under the emperor Vespasian in 70 AD, and was completed in 80 AD under his successor and heir Titus. Further modifications were made during the reign of Domitian (81–96). These three emperors are known as the Flavian dynasty, and the amphitheatre was named in Latin for its association with their family name (Flavius). The Colosseum could hold, it is estimated, between 50,000 and 80,000 spectators. it had more than 60 numbered entrances, and visitors exited through the same gate through which they had entered. In fact, exits were located side by side, around the entire circumference of the Coliseum. As a consequence, the Coliseum could be evacuated within just about 5 minutes, an efficiency that is not even reached by modern stadia due to their smaller number of exits.
  • Spectators were given tickets in the form of numbered pottery shards, which directed them to the appropriate section and row. They accessed their seats via vomitoria (singular vomitorium), passageways that opened into a tier of seats from below or behind. These quickly dispersed people into their seats and, upon conclusion of the event or in an emergency evacuation, could permit their exit within only a few minutes. The name vomitoria derived from the Latin word for a rapid discharge, from which English derives the word vomit.

  • Most published event in English medical journal is the Hillsborough disaster in 1989. The 1989 Hillsborough disaster was an incident that occurred during the FA Cup semi-final match between Liverpool and Nottingham Forest football clubs on 15 April 1989 at the Hillsborough Stadium in Sheffield, England. The crush resulted in the deaths of 96 people and injuries to 766 others. The incident has since been blamed primarily on the police. The incident remains the worst stadium-related disaster in British history and one of the world's worst football disasters

  • The Maha Kumbha Mela is held at Allahabad (Prayag) (27 January to 10 March 2013). An estimated 30 million people visited the Maha Kumbh Mela on 10 February 2013 and an estimated 100 million are expected to visit the place during the festival spread over 55 days. On 10 February 2013 a stampede at the railway station killed 36 and injured at least 39.[49] In the vast crowds some elderly people, predominantly women, are abandoned by their families. Here are the details of most auspicious days (bathing dates) in year 2013 during Maha Kumbh Festival (mela).[50] 14 January 2013 (Monday) – Makar Sankranti 27 January 2013 (Sunday) – Paush Purnima 6 February 2013 (Wednesday) – Ekadashi Snan 10 February 2013 (Sunday) – Mauni Amavasya Snan (Main Bathing Day) 15 February 2013 (Friday) – Vasant Panchami Snan 17 February 2013 (Sunday) – Rath Saptami Snan 21 February 2013 (Thursday) – Bhisma Ekadashi Snan 25 February 2013 (Monday) – Maghi Purnima Snan 10 March 2013 (Sunday) – Mahashivratri
