METHODS: This is a retrospective analysis of pediatric RTA presenting to a Nigerian referral center. [ncbi.nlm.nih.gov]

• Contusion

  The results also suggest that a 50% probability of contusions corresponds to CSDM value of 48% at strain levels of 0.2, and the 50% probability of contusions corresponds to a DDM value of 6.7%. Copyright © 2018 Elsevier Ltd. All rights reserved. [ncbi.nlm.nih.gov]

  A number of physical injuries can commonly result from the blunt force trauma caused by a collision, ranging from bruising and contusions to catastrophic physical injury (e.g., paralysis) or death. A 1985 study by K. [en.wikipedia.org]

• Left Shoulder Pain

  A 38- year-old male with left shoulder pain, scapular deviation and weakness in the left upper extremity, whose symptoms developed over a two-year period following a traffic accident, is presented herein. [ncbi.nlm.nih.gov]

Metastatic workup showed no nodal or distant spread, T1N0M0 stage I. After orchiectomy, the patient underwent adjuvant external beam radiotherapy to the para-aortic nodes. [emedicine.medscape.com]

PET scanning is not usually part of the initial workup but may be useful in tracking activity and growth in residual masses following definitive chemotherapy. [9] [3] [10] [11] Several laboratory values may be useful in following tumor burdens. [ncbi.nlm.nih.gov]

Treatment and rehabilitation of severe injuries can take months or even years. [web.archive.org]

In additional to history, clinical manifestation, and prognosis, evaluating the distribution of hypointense lesions in susceptibility-weighted imaging could be useful to differentiate these 2 conditions. [ncbi.nlm.nih.gov]

Prognosis Prognosis is good but depends on the stage of disease with 5- year survival rates as high as 99% in stage 1 disease. [orpha.net]

Excellent prognosis with >95% cure rate for stage I and II. Main differential diagnosis: (other GCTs that can have solid growth) Embryonal carcinoma: exhibits cellular pleomorphism and nuclear overlap, CD30+ and keratin+. [auanet.org]

Prognosis is good for all stages with greater than 90% cure rate. [radiopaedia.org]

This pattern of etiologic factors is in accordance with data from most developing countries. [ncbi.nlm.nih.gov]

Etiology Etiology is unknown but tumors are thought to arise from an embryonic germ cell leading to testicular intraepithelial neoplasia (the precursor to classical seminoma). [orpha.net]

Etiology Based on the presumed origin of spermatocytic seminoma from mature (postpubertal) germ cells, it has been hypothesised that the increased proliferation of these cells causes the growth of the tumours, but the etiology has long been unknown. [atlasgeneticsoncology.org]

The overall prevalence of seminoma generally increases with age. [8] Pathophysiology Testicular seminoma originates in the germinal epithelium of the seminiferous tubules. [ncbi.nlm.nih.gov]

Pathophysiology Testicular seminoma is a pathologic diagnosis in which only seminomatous elements are observed upon histopathologic review after a radical orchiectomy and in which serum alpha-fetoprotein (AFP) is within the reference range. [emedicine.medscape.com]

CONCLUSION: Pediatric RTA deaths in this study were due mainly to preventable causes. [ncbi.nlm.nih.gov]

Simple prevention measures could halve the number of deaths, the report said. [news.bbc.co.uk]
