Cardiac insufficiency caused by myocardial iron overload(MIO)is a leading cause of death for patients with thalassemia and primary hemochromatosis,but easy to be missed or misdiagnosed due to the lack of typical clinical symptoms.Cardiac MR(CMR)has high tissue resolution without radiation,having become an important imaging method for evaluating MIO.The application progresses of CMR for assessing MIO were reviewed in this article.

The condition of patients with severe traumatic brain injury (sTBI) complicated by corona virus 2019 disease (COVID-19) is complex. sTBI can significantly increase the probability of COVID-19 developing into severe or critical stage, while COVID-19 can also increase the surgical risk of sTBI and the severity of postoperative lung lesions. There are many contradictions in the treatment process, which brings difficulties to the clinical treatment of such patients. Up to now, there are few clinical studies and therapeutic norms relevant to sTBI complicated by COVID-19. In order to standardize the clinical treatment of such patients, Critical Care Medicine Branch of China International Exchange and Promotive Association for Medical and Healthcare and Editorial Board of Chinese Journal of Trauma organized relevant experts to formulate the Chinese expert consensus on clinical treatment of adult patients with severe traumatic brain injury complicated by corona virus infection 2019 ( version 2023) based on the joint prevention and control mechanism scheme of the State Council and domestic and foreign literatures on sTBI and COVID-19 in the past 3 years of the international epidemic. Fifteen recommendations focused on emergency treatment, emergency surgery and comprehensive management were put forward to provide a guidance for the diagnosis and treatment of sTBI complicated by COVID-19.

Objective To investigate standard diagnosis and treatment of cerebrospinal fluid (CSF) leakage to improve the prognosis of the patients. Methods A retrospective study was done on 75 patients with CSF leakage from January 2004 to March 2007 in our hospital. There were 51 patients with rhinorrhea, nine with otorrhea and 15 with wound/incision leakage. Of all, 39 patients had traumatic leakage, 32 postoperative leakage and four spontaneous leakage. In the study, 23 patients were cured by position testing and drug therapy and 16 by cerebrospinal fluid drainage and/or wound debridement but 36 were treated with surgeries including craniotomy repair in 17, extracranial repair in 17 and CSF shunt in five (three received CSF shunt after repair). Results Of all, 64 patients were cured, 10 gained im-provement but one died. Conclusion Standard diagnosis and treatment of CSF leakage helps improve cure rate and reduce complications.
