Effect of SARS-CoV-2 infection on anti-HLA antibodies and de novo donor specific antibodies incidence in lung transplant recipients.

Purpose: There are no clear guidelines on how to handle immunosuppression in lung transplant recipients (LTRs) infected by SARS-CoV-2. Antimetabolite reduction with corticosteroid escalation is the most frequent strategy. The aim of this study was to determine the effect of this therapeutic approach on the incidence of de novo donor specific-antibodies (dnDSA).

Biopsy of lung lesions under CT control.

Objectives: With the increasing number of detected lung nodules and the need for morphological verification, the number of CT- controlled biopsies is increasing. The aim of this study was to assess the risks and benefits of these biopsies.

Methods: This is a prospective and observational study.

Intravenous vs. oral hydration administration for optimal ureteral opacification in computer tomographic urography.

Purpose: Computed tomographic urography (CTU) is the gold standard in the radiologic detection of urinary tract disease. The goals of CTU protocols are to garner fully distended and opacified collecting systems, ureters, and bladder for adequate evaluation. Multiple techniques have been reported in the literature to optimize urinary tract visualization and enhance genitourinary assessment.

Primary liver tumors in pediatric patients: proper imaging technique for diagnosis and staging.

Liver tumors in children are rare and comprise a diverse set of both benign and malignant lesions, most of which are not clinically detected until they are large and often difficult to resect. Technological advances in diagnostic imaging have greatly influenced the surgical planning of these lesions and ultimately the clinical outcome. The intent of this article is to present an imaging algorithm for the effective and efficient workup of liver tumors in pediatric patients.

Magnetic resonance enterography in evaluation and management of children with Crohn's disease.

The role of radiologic evaluation in Crohn's disease (CD) has undergone a recent paradigm shift in which the radiologist adds value to the multidisciplinary team by longitudinally assessing therapeutic response and identifying treatment-modifying subtypes, such as fibrostenotic or fistulizing disease. Magnetic resonance enterography (MRE) has become the primary imaging modality used. The combination of multiplanar, multiparametric, and multiphasic contrast-enhanced imaging with the high spatial resolution and very high tissue contrast of MR imaging allows for detailed evaluation of intra-abdominal pathology, without the risk of cumulative radiation exposure.

Renal lymphoma: MR appearance with diffusion-weighted imaging.

Imaging of renal lymphoma on magnetic resonance imaging and diffusion-weighted imaging is not well documented in the literature. We present a case of renal lymphoma in a 61-year-old patient with computed tomography and magnetic resonance imaging correlation. The lymphomatous lesions demonstrate mild enhancement and restricted diffusion.

Diffusion-weighted MRI of renal cell carcinoma, upper tract urothelial carcinoma, and renal infection: a pictorial review.

Diffusion-weighted (DW) magnetic resonance imaging (MRI) is a functional imaging technique that derives image contrast from differences in water molecule diffusion within tissues. DW MRI helps detect and characterize renal and urothelial malignancies, may help in differentiating some benign from malignant renal masses, and can also recognize renal and upper urinary tract infections. Patients precluded from receiving intravenous contrast agents may particularly benefit from this technique.

Imaging of the placenta with pathologic correlation.

The placenta functions to nourish and protect the fetus. Imaging of the placenta can have a profound impact on patient management, owing to the morbidity and mortality associated with various placental conditions. To fully appreciate placental pathology, its physiology, anatomy, and variant anatomy will be outlined.

Adnexal masses in pregnancy.

Adnexal masses are often seen in the gravid patient. With current advances in technology, an increased number of adnexal masses are incidentally discovered on antenatal screening ultrasonography examinations. Sonography is the first-line imaging modality for any adnexal mass.

Spectrum of CT findings in rupture and impending rupture of abdominal aortic aneurysms.

Prompt diagnosis of rupture and impending rupture of abdominal aortic aneurysms is imperative. The computed tomographic (CT) findings of ruptured abdominal aortic aneurysms are often straightforward. Most ruptures are manifested as a retroperitoneal hematoma accompanied by an abdominal aortic aneurysm.

Temporal interrelationships among fatigue, circadian rhythm and depression in breast cancer patients undergoing chemotherapy treatment.

Seventy-eight female breast cancer patients were assessed for fatigue, depression, overall mood, and circadian rhythm at their second and fourth on-study chemotherapy cycles as part of a larger study examining the efficacy of paroxetine in reducing chemotherapy-induced fatigue. The Multidimensional Assessment of Fatigue (MAF), the Fatigue Symptom Checklist (FSCL), the Center for Epidemiologic Studies-Depression [CES-D) questionnaire, the Hamilton Depression Inventory (HDI), and the Profile of Mood States (POMS) were completed by patients at home 7 days after each treatment to assess symptom severity. Circadian rhythm was assessed over a 72-h period with the Mini-Motionlogger Actigraph (Ambulatory Monitoring, Ardsley, NY), starting 6 days after treatment.
