Radiation overexposure is common in chest X-ray (CXRs) of pediatric patients. However, overexposure may reveal incidental findings that can help to guide patient management or warrant quality improvement. To assess the prevalence of overexposure in CXRs in pediatric intensive care unit (PICU); and identify the incidental findings within overexposed areas, we conducted a retrospective cohort study of children who were admitted to PICU. ⋯ Appropriate collimation of the X-ray beam, rather than electronically cropping the image, is highly recommended to minimize hiding incidental findings in the cropped-out areas. Redefining the anatomic boundaries of CXR in critically ill infants and children may need further studies and consideration. Quality improvement initiatives to minimize radiation overexposure in PICU are recommended, especially in younger children and those with more severe illness upon PICU admission.

Severe refractory idiopathic inflammatory myopathy (IIM) represents a challenge for the clinician. The lack of efficacy of available tools reflects our incomplete insight into the molecular events sustaining the inflammatory tissue damage in these patients. We present the first case of refractory IIM treated with anti-dipeptidyl peptidase-4 (DPP-4)/cluster of differentiation 26 (CD26) monoclonal antibody. ⋯ Blockade of DPP-4/CD26, which is expressed on T cells and mediates T cell activation and function, is safe and might be effective in patients with refractory DM.

Lipoprotein a (Lp (a)) and coronary artery calcification (CAC) are markers of coronary artery and cardiovascular diseases. However, the association between Lp (a) and CAC in asymptomatic individuals remains unclear. In this study, we aimed to determine the influence of Lp (a) on CAC in asymptomatic individuals. ⋯ The same result was observed in men aged ≥45 years (P < .01). Lp (a) is an independently associated factor of CAC and a marker of coronary atherosclerosis in asymptomatic men aged ≥45 years. In asymptomatic men aged ≥45 years, Lp (a) should be measured, and intensive Lp (a)-lowering treatment should be considered.

Case Reports
Genetic analysis of rapidly progressing esophageal squamous cell carcinoma: A case report.
Numerous investigations have been performed to explore candidate biomarker proteins in esophageal squamous cell carcinoma (ESCC) patients, which could predict the response to chemoradiotherapy (CRT). Here we report a patient with unresectable ESCC who had unsatisfactory effects with radiotherapy, chemotherapy and immunotherapy. We performed genetic analysis in this patient to gain insights about the cause of the rapid progression. ⋯ Although the role of TP53 gene and PIK3CA gene in the progression, treatment and sensitivity of esophageal cancer has been studied, the mechanism of their simultaneous appearance has not been demonstrated in relevant studies. We speculate that the reason for the rapid progression in this patient during active treatment might be related to this. Further studies are needed to validate our observations.

An abdominal pseudohernia is a protrusion of the abdominal wall that there is no actual muscular disruption. This report presents a case in which abdominal muscle activities were accurately and quantitatively measured using ultrasonography (US) and surface electromyography in a patient with abdominal pseudohernia. ⋯ By using these outstanding assessment methods, proper diagnosis and rehabilitation treatment strategies can be developed.
