Fifteen cases of diffuse axonal injury(DAI) brought about by nonmissile head injury in humans are analyzed. All cases were subjected to comprehensive clinical studies such as measurement of cerebral blood flow by SPECT, continuous intracranial pressure monitoring and multimodality evoked potentials(MEPs). In the patients with DAI, a high incidence of low cerebral perfusion and abnormal MEPs. especially auditory evoked potentials, were found, with high incidence of high velocity traffic accident injury mechanism. On the other hand, a low incidence of increased intracranial pressure was found and dehydrating agents such as glycerol and mannitol did not exert a beneficial influence upon the clinical courses or the outcomes. The outcome of the patients with DAI depended upon the duration of coma and whether or not brain stem signs were noted.

Purpose: Immune checkpoint inhibitors (ICIs) have been shown significant oncological improvements in several cancers.However, ICIs are still in their infancy in hepatocellular carcinoma (HCC). Programmed cell death-ligand 1 (PD-L1), tumorinfiltrating lymphocytes (TILs), and epithelial-mesenchymal transition (EMT) have been known as prognostic factors in HCC. Therefore, we have focused on identifying the molecular mechanisms between each marker to evaluate a predictive role. Methods: Formalin-fixed paraffin-embedded samples were obtained from 166 patients with HCC who underwent surgery. The expression of PD-L1 and TILs and EMT marker were evaluated by immunohistochemical analysis. Results: The multivariate analysis showed that TIL expression (hazard ratio [HR], 0.483; 95% confidence interval [CI], 0.269–0.866; P = 0.015) were independent prognostic factors for overall survival. The prognostic factors for disease-free survival were EMT marker expression (HR, 1.565; 95% CI, 1.019–2.403; P = 0.005). Patients with high expression of TILs had significantly better survival compared to patients with low expression (P = 0.023). Patients who were TIL+/EMT– showed a significantly better prognosis than those who were TIL–/EMT+ (P = 0.049). Conclusion This study demonstrates that PD-L1 expression of TILs is closely associated with EMT marker expression in HCC. Clinical investigations using anti–PD-1/PD-L1 inhibitors in patients with EMT-associated PD-L1 upregulation are warranted.

The Clinical Research Center for Dementia of South Korea (CREDOS), a nation-wide clinical dementia research group, has prepared clinical practice guidelines (CPG) for dementia tailored to the Korean population. In this article, a summary of the CREDOS CPG is presented with the Korean and English version of full report included in the appendix. The CREDOS CPG in intended not only for psychiatrists and neurologists, but also internists, family physicians, and other primary care physicians involved in the prevention and early diagnosis of dementia. While our CPG for dementia mainly covers Alzheimer's disease (AD) and vascular dementia (VaD), it also includes mild cognitive impairment (MCI) and vascular MCI, which are currently known to be the preclinical stages of AD or VaD, respectively, with emphasis placed on early diagnosis. The CREDOS CPG aims to achieve the following goals by developing CPG for dementia: to establish evidence-based, objective and clear clinical standards for dementia; to improve the clinical decision-making process for patients with dementia; to provide scientific and systematic scales to aid in the work of dementia specialists; to suggest comprehensive and systematic healthcare services tailored to each dementia subtype. The CREDOS CPG focuses on diagnosis and evaluation of clinical practice available domestically, and provides useful concepts of dementia. Its emphasis is on etiologies and epidemiology, diagnostic criteria and evaluation, neuropsychological tests, behavioral and psychological symptoms, the activities of daily living, laboratory tests, and brain imaging.
