BACKGROUND: After appropriate initial therapy for patients with stage II-III melanoma, there is no consensus regarding surveillance. Thus, follow-up is highly variable among institutions and individual providers. The National Comprehensive Cancer Network recommends routine clinical examination and consideration of imaging for stage IIB-IIIC every 3-12 mo with no distinction between stages. Detection of recurrence is important as novel systemic therapies and surgical resection of recurrence may provide survival benefits...

OBJECTIVE Posttraumatic hydrocephalus (PTH) affects 11.9%-36% of patients undergoing decompressive craniectomy (DC) and is an important cause of morbidity after traumatic brain injury (TBI). Early diagnosis and treatment of PTH can prevent further neurological compromise in patients who are recovering from TBI. There is limited data on predictors of shunting for PTH after DC for TBI. METHODS Prospectively collected data from the erythropoietin severe TBI randomized controlled trial were studied. Demographic, clinical, and imaging data were analyzed for enrolled patients who underwent a DC...

BACKGROUND: Progressive hemorrhagic injury (PHI) is common in patients with severe traumatic brain injury (TBI) and is associated with worse outcomes. PHI pathophysiology remains poorly understood and difficult to predict. We performed an exploratory analysis aimed at identify markers in need of further investigation to establish their predictive value in PHI following TBI. METHODS: We performed a retrospective chart review of prospectively collected data from 424 highest-level activation trauma patients from January 2012 through December 2013...

BACKGROUND: Respective proportions of final etiologies are disparate in cohorts of cardiac arrest patients, depending on examined population and diagnostic algorithms. In particular, prevalence and characteristics of sudden unexplained death syndrome (SUDS) are debated. We aimed at describing etiologies in a large cohort of aborted out-of-hospital cardiac arrest (OHCA) patients, in order to assess prevalence and outcome of SUDS. PATIENTS AND METHODS: We analyzed data from our prospective registry of successfully resuscitated OHCA patients admitted to a cardiac arrest centre between January 2002 and December 2014...

BACKGROUND: Spasmus Nutans (SN) is a rare pediatric ophthalmologic syndrome of nystagmus, head bobbing and abnormal head positioning. Historically, SN has been associated with underlying optic pathway gliomas (OPG); however, evidence of this is association is based primarily on a small number of isolated case reports. Prior retrospective analyses have found the rate of OPG to be less than 2%, but only intermittently utilized neuroimaging with CT, which has limited sensitivity for detection of small lesions in the optic pathway...

BACKGROUND: TBI is a leading cause of death and disability worldwide. The incidence of TBI in LMICs is disproportionately high, with an associated increased risk of mortality from TBI relative to high-income countries. While CT is the diagnostic method of choice, this is often unavailable in LMICs. Exploratory burr holes may provide a suitable choice for diagnosis and treatment of TBI. METHODS: We performed a retrospective review of prospectively collected data at KCH, a tertiary care center in Lilongwe, Malawi...

PURPOSE: The paranasal sinuses are complex anatomical structures of unknown significance. One hypothesis theorizes that the sinuses, in the event of a traumatic injury, function as a crumple zone to distribute and absorb energy to protect the brain and other critical structures. The current study investigates the association between frontal sinus (FS) volume and the severity of cerebral insults following craniofacial trauma. METHODS: All patients with FS fracture admitted to a level 1 trauma center from 2011 to 2014 were retrospectively reviewed...

REVIEW
Gaston A Rodriguez-Granillo
A large number of studies support the increasingly relevant prognostic value of the presence and extent of delayed enhancement (DE), a surrogate marker of fibrosis, in diverse etiologies. Gadolinium and iodinated based contrast agents share similar kinetics, thus leading to comparable myocardial characterization with cardiac magnetic resonance (CMR) and cardiac computed tomography (CT) at both first-pass perfusion and DE imaging. We review the available evidence of DE imaging for the assessment of myocardial infarction (MI) using cardiac CT (CTDE), from animal to clinical studies, and from 16-slice CT to dual-energy CT systems (DECT)...

BACKGROUND AND PURPOSE: Although microcephaly is the most prominent feature of congenital Zika syndrome, a spectrum with less severe cases is starting to be recognized. Our aim was to review neuroimaging of infants to detect cases without microcephaly and compare them with those with microcephaly. MATERIALS AND METHODS: We retrospectively evaluated all neuroimaging (MR imaging/CT) of infants 1 year of age or younger. Patients with congenital Zika syndrome were divided into those with microcephaly at birth, postnatal microcephaly, and without microcephaly...
