Late morbidity and mortality following revascularization surgery for moyamoya disease in the pediatric population.

J Neurosurg Pediatr 2021 Jun 11:1-6. Epub 2021 Jun 11.

Objective: There are limited reports on long-term morbidity in pediatric patients who have undergone surgical revascularization for moyamoya disease (MMD). Here, the authors report long-term morbidity and mortality in a population of pediatric patients who underwent pial synangiosis for MMD from 1988 through 2016.

Methods: A single-center retrospective review of the hospital and personal operative databases of the senior authors was carried out to identify all patients who were treated for MMD at Boston Children's Hospital between 1988 and 2016, and who experienced any episode of late morbidity or mortality, which the authors defined as an event resulting in significant neurological deficit or death occurring more than 1 year after revascularization surgery.

Pain Trajectories Following Subarachnoid Hemorrhage are Associated with Continued Opioid Use at Outpatient Follow-up.

Neurocrit Care 2021 Jun 9. Epub 2021 Jun 9.

Department of Neurology, School of Medicine, University of Maryland, Baltimore, MD, USA.

Background: Subarachnoid hemorrhage (SAH) is characterized by the worst headache of life and associated with long-term opioid use. Discrete pain trajectories predict chronic opioid use following other etiologies of acute pain, but it is unknown whether they exist following SAH. If discrete pain trajectories following SAH exist, it is uncertain whether they predict long-term opioid use. Read More

Clinical Presentation, Patient Assessment, Anatomy, Pathophysiology, and Imaging of Pelvic Venous Disease.

Semin Intervent Radiol 2021 Jun 3;38(2):233-238. Epub 2021 Jun 3.

Division of Interventional Radiology, Department of Radiology, Thomas Jefferson University Hospital, Philadelphia, Pennsylvania.

Pelvic venous disorders (PeVDs) can result in several different clinical presentations, but can be challenging to distinguish from other etiologies of chronic pelvic pain (CPP). Clinical evaluation of CPP patients optimally should be performed in a multidisciplinary fashion and patients who may have PeVD should be referred for consultation with a vascular interventionalist whose evaluation would utilize an imaging workup to search for pelvic varices. Additionally, it is critical to quantify the quality-of-life effects of all CPP to determine the impact on the patient's overall health. Read More

Wound Care for Venous Ulceration.

Semin Intervent Radiol 2021 Jun 3;38(2):194-201. Epub 2021 Jun 3.

Harvard Medical School, Department of Radiology, Beth Israel Deaconess Medical Center, Boston, Massachusetts.

Venous leg ulcers (VLUs) affect as many as 20% of patients with advanced chronic venous insufficiency and are associated with significant morbidity and health care costs. VLUs are the most common cause of leg ulcers; however, other etiologies of lower extremity ulcerations should be investigated, most notably arterial insufficiency, to ensure appropriate therapy. Careful clinical examination, standardized documentation, and ultrasound evaluation are needed for diagnosis and treatment success. Read More

Diffusion-weighted imaging reveals distinct patterns of cytotoxic edema in patients with subdural hematomas.

J Neurotrauma 2021 Jun 9. Epub 2021 Jun 9.

University of Cincinnati, 2514, Neurology and Rehabilitation Medicine, Cincinnati, Ohio, United States;

Subdural hematomas (SDHs) are increasingly common and can cause ischemic brain injury. Prior work has suggested that this is driven largely by vascular compression from herniation, although this work was done prior to the era of magnetic resonance imaging (MRI). We thus sought to study SDH-related ischemic brain injury by looking at patterns of cytotoxic edema on diffusion-weighted MRI. Read More

COVID-19 associated brain/spinal cord lesions and leptomeningeal enhancement: A meta-analysis of the relationship to CSF SARS-CoV-2.

J Neuroimaging 2021 Jun 8. Epub 2021 Jun 8.

Department of Neurology, NYU Langone Medical Center, New York, New York, USA.

Background And Purpose: We reviewed the literature to evaluate cerebrospinal fluid (CSF) results from patients with coronavirus disease 2019 (COVID-19) who had neurological symptoms and had an MRI that showed (1) central nervous system (CNS) hyperintense lesions not attributed to ischemia and/or (2) leptomeningeal enhancement. We sought to determine if these findings were associated with a positive CSF severe acute respiratory syndrome associated coronavirus 2 (SARS-CoV-2) polymerase chain reaction (PCR).

Methods: We performed a systematic review of Medline and Embase from December 1, 2019 to November 18, 2020. Read More

Optimizing the diagnosis and assessment of chronic thromboembolic pulmonary hypertension with advancing imaging modalities.

Pulm Circ 2021 Apr-Jun;11(2):20458940211007375. Epub 2021 May 24.

Cardiothoracic Imaging, University of California San Diego, La Jolla, CA, USA.

Imaging is key to nearly all aspects of chronic thromboembolic pulmonary hypertension including management for screening, assessing eligibility for pulmonary endarterectomy, and post-operative follow-up. While ventilation/perfusion scintigraphy, the gold standard technique for chronic thromboembolic pulmonary hypertension screening, can have excellent sensitivity, it can be confounded by other etiologies of pulmonary malperfusion, and does not provide structural information to guide operability assessment. Conventional computed tomography pulmonary angiography has high specificity, though findings of chronic thromboembolic pulmonary hypertension can be visually subtle and unrecognized. Read More

Tumor metabolism and associated serum metabolites define prognostic subtypes of Asian hepatocellular carcinoma.

Sci Rep 2021 Jun 8;11(1):12097. Epub 2021 Jun 8.

Laboratory of Human Carcinogenesis, Center for Cancer Research, National Cancer Institute, Bethesda, MD, 20892, USA.

Treatment effectiveness in hepatocellular carcinoma (HCC) depends on early detection and precision-medicine-based patient stratification for targeted therapies. However, the lack of robust biomarkers, particularly a non-invasive diagnostic tool, precludes significant improvement of clinical outcomes for HCC patients. Serum metabolites are one of the best non-invasive means for determining patient prognosis, as they are stable end-products of biochemical processes in human body. Read More
