Pneumonia remains a major cause of childhood mortality and morbidity globally. Accurate diagnosis and attribution of the causes of pneumonia are important for measuring the burden of disease, implementing appropriate preventive or treatment strategies, and developing more effective interventions. This review summarizes recent diagnostic advances in radiological techniques, specimen collection, and laboratory methods. Although chest ultrasound and chest magnetic resonance imaging are promising modalities for radiological diagnosis, their role in clinical management and their impact on outcomes need further study...

Adrenal cortical hyperplasia manifests radiologically as the nonmalignant growth, or enlargement of the adrenal glands, specifically the cortex, although the cortex cannot be definitively identified by conventional imaging. Controlled by the pituitary gland, the adrenal cortex drives critical processes, such as cortisol, mineralocorticoid, and sex hormone production. Any disruption in the multiple enzymes and hormones involved in these pathways may cause serious or life-threatening symptoms, often associated with anatomical changes of the adrenal glands...

In recent years, multiparametric magnetic resonance imaging (MRI) and MR/ultrasound (US) fusion targeted biopsy (TB) have become more widely adopted to aid in prostate cancer (PCa) detection. Previously, TB has been found to increase the yield of clinically significant PCa and is more likely to sample the index tumor compared to traditional 12-core extended sextant biopsies. Currently the prognostic significance of perineural invasion (PNI) when identified on TB (PNI-TB) is unknown. We identified 95 men at two tertiary referral centers who underwent TB followed by radical prostatectomy between January 2014 and January 2017...

Intraductal Papillary Mucinous Neoplasms (IPMNs) are the most common cystic tumors of the pancreas and are considered premalignant lesions. IPMNs are characterized by the papillary growth of the ductal epithelium with rich mucin production, which is responsible for cystic segmental or diffuse dilatation of the main pancreatic duct (MPD) and/or its branches. According to the different involvement of pancreatic duct system, IPMNs are divided into main duct type (MD-IPMN), branch duct type (BD-IPMN), and mixed type (MT-IPMN)...

Fetal and neonatal alloimmune thrombocytopenia (FNAIT) is the most common cause of severe neonatal thrombocytopenia and intracranial bleeding in term newborns. Intracranial hemorrhage (ICH) commonly results in death or severe, lasting neurologic disability. The timing of ICH is also important for management of the next affected pregnancy in cases of FNAIT. This manuscript reviews the advantages and disadvantages of the different radiologic methodologies to identify and characterize ICH. It discusses the limits of ultrasound and the advantages of magnetic resonance imaging allowing avoidance of the radiation associated with computed tomography (CT) scans...

Chronic kidney disease (CKD) is defined as an alteration of kidney function and/or structure lasting for more than 3 months and is a major public health issue. Histologically, the severity of CKD correlates with the magnitude of kidney cortical interstitial fibrosis. Estimation of kidney fibrosis is crucial to assess prognosis and guide therapy in both native and allograft kidneys. Biopsy is currently the gold standard for assessing fibrosis with histological techniques. Although this procedure has become safer over recent years, complications and limitations remain...
