The Analysis of Escalator-related Injuries in Aging Population

PURPOSE: Escalator-related injuries have been considered uncommon and most likely to occur to children. We set out to describe the epidemiology of these injuries with focus on the aging population in order to determine whether or not escalators are safe for the aged, and in order to obtain information to help in preventing escalator-related injuries. METHODS: A prospective survey was undertaken to identify the number and nature of these injuries from May 2004 to June 2006. We enrolled patients who had sustained escalated- related injuries and a standard list of questions and answers were recorded by the emergency physician. A total of 54 Such questionnaires were completed during the study period. Data were analyzed using SPSS 12.0K. RESULTS: The average patient age 63.40+/-20.92 years (range 3-94). There were 18 (33.3%) males. Only 4 (7.4%) were younger than their sixteen year, but 36 (66.7%) were over age 65 and 17 of those were injured from standing on escalators. However of 18 patients younger than age 65, 13 were injured from walking on moving escalators. CONCLUSION: Escalator-related injuries are not as uncommon as previously believed and the aged population over 65 years old is the highest risk group. Additionally, walking on moving escalator was a cause of injuries. Therefore, two orimary prevention strategies are needed. Provision of alternatives to escalators for people over 65 and keeping passengers from walking on escalators.

Traumatic Rupture of Hepatocellular Carcinoma

A 45-year-old man presented at the emergency department with severe whole abdominal pain. He was struck on the abdomen by a soccer ball in the soccer game 12 hours ago. Initial vital signs were unstable, but stabilized soon after fluid resuscitation. CT scans were performed to diagnose injury to the intraabdominal organs. CT scans showed hemoperitoneum and rupture of hepatocellular carcinoma (HCC). Transarterial chemoembolization and catheter drainage were performed. He was discharged on the 22th day. Rupture of HCC is mostly occurred in the advanced stage of HCC, but very rarely happened after abdominal trauma. Treatment of choice for traumatic rupture of HCC was not established yet. In our case, the patient was cured by transarterial chemoembolization without laparotomy. Considering that the treatment for traumatic liver injury is supportive care or laparotomy, emergency physician should remember that traumatic rupture of HCC also can cause hemoperitoneum after abdominal trauma.

A Case of Omental Infarct with Right Lower Quadrant Pain

A 56-year-old man was transferred to the emergency department complaining of right lower quadrant pain of 3 days duration. The Maximal tender area was the slightly upper part of the abdomen up to McBurney's point. We ordered CT to evaluate for several disease such as appendicitis, diverticulitis and primary epiploic appendagitis, and the patient was diagnosed with omental infarct based on the CT finding. After five days of supportive care, the symptoms were resolved. Omental infarct is a rare cause of acute abdominal pain, which is often misdiagnosed as acute appendicitis when it presents with right lower quadrant pain. Although surgical resection is required in severe cases, most cases are successfully managed with supportive treatment. The emergency physician should consider omental infarct as a differential diagnosis in patients with right lower quadrant pain.
