PURPOSE:  The primary aim of dynamic stabilization is to stabilize the spine and preserve function without overstressing adjacent segments, which is a potential risk of fusion surgery. However, direct comparative analyses of the two approaches are still limited, and little is known about the association of patient-reported outcomes with these treatment options. OBJECTIVE:  To compare the clinical outcomes of dynamic posterior stabilization using the DSS Stabilization System (Paradigm Spine, LLC, New York, New York, United States) versus posterior lumbar intervertebral fusion (PLIF) based on data from a spine registry...

Caseous calcification of the mitral annulus (CCMA) is considered a rare variant of mitral annular calcification (MAC) due to caseous transformation of the inner material and prevalence of CCMA, about 0.63% of all MAC cases and 0.06%-0.07% of the population. The precise pathophysiology of CCMA is still unknown. It is a chronic degenerative disorder common in the elderly, particularly in women. Caseous calcification of the mitral annulus (CCMA) is a soft peri-annular extensive calcification, resembling cardiac tumors, abscesses, vegetation, or calcified thrombus, which is composed of an admixture of calcium, fatty acids, and cholesterol with a toothpaste-like texture...

Argentina has two endemic areas of paracoccidioidomycosis (PCM). Bordering Paraguay and Brazil, Northeast Argentina (NEA) comprises the area with the highest incidence where the chronic adult clinical form has historically been reported. Juvenile form in children and adolescents is rare in this area since only one case was reported in the last 10 years. Despite this, between 2010 and 2012, several cases of acute/subacute clinical forms in children aged 10 to 16 (median 12) were detected. In the last decade, the NEA region has been exposed to ecological variations as consequences of certain climatic and anthropogenic changes, including El Niño-Southern Oscillation phenomenon during 2009, and deforestation...

Family- and population-based genetic studies have successfully identified multiple disease-susceptibility loci for Age-related Macular Degeneration (AMD), one of the first batch and most successful examples of genome-wide association study (GWAS). However, most genetic studies to date have focused on case-control studies of late AMD (choroidal neovascularization [CNV] or geographic atrophy [GA]). The genetic influences on disease progression are largely unexplored. We assembled unique resources to perform a genome-wide bivariate time-to-event analysis to test for association of time-to-late-AMD with ∼9 million variants on 2,721 Caucasians from a large multi-center randomized clinical trial, the Age-Related Eye Disease Study...

OBJECTIVES: In patients referred to off-pump coronary artery bypass grafting, pulmonary vein isolation (PVI) may be used for those with persistent atrial fibrillation (AF), an alternative to the Maze procedure. However, the success rate of PVI in persistent AF is limited. The study assesses the prognostic value of focal epicardial electrocardiography of the pulmonary veins (PVs) for surgical ablation results. METHODS: We mapped 140 PV in 35 cases undergoing off-pump coronary artery bypass grafting...

Background: Interest in vitamin D has increased during the past 2 decades, with a corresponding increase in laboratory testing of 25-hydroxyvitamin D [25(OH)D]. The vast majority of specimens tested display normal or deficient levels of 25(OH)D; concentrations rarely fall in the potentially toxic range. Methods: We performed a retrospective investigation of elevated 25(OH)D levels during a 16-year period at the University of Iowa Hospitals and Clinics (UIHC), a 734-bed tertiary-/quaternary-care academic medical center in the midwestern United States...

In esophageal squamous cell carcinoma (ESCC) patients who are treated with chemoradiotherapy (CRT), identification of the presence or absence of residual or recurrent carcinoma is usually pivotal in their clinical management. In addition, the extent of carcinoma invasion into the esophageal wall could determine the clinical outcome of these patients following CRT. Therefore, in this study, we evaluated the response to CRT both macroscopically and histologically in a consecutive series of 42 ESCC patients receiving neoadjuvant chemoradiotherapy following curative esophageal resection at Tohoku University Hospital between August 2011 and December 2012...

Aims: Measurements with superior reproducibility are useful clinically and research purposes. Previous reproducibility studies of Doppler assessment of aortic stenosis (AS) have compared only a pair of observers and have not explored the mechanism by which disagreement between operators occurs. Using custom-designed software which stored operators' traces, we investigated the reproducibility of peak and velocity time integral (VTI) measurements across a much larger group of operators and explored the mechanisms by which disagreement arose...

Here, we describe a patient with bilateral breast cancer and melanoma, and with a concomitant double variant, namely p.Gln563Ter in BRCA1 and p.Lys3326Ter in BRCA2. The BRCA2 p.Lys3326Ter (K3326X) (rs11571833) mutation identified in our patient is a debated substitution of thymidine for adenine which is currently regarded as benign polymorphism in main gene databases. Recent studies, however, describe this variant as associated with breast and ovarian tumors. Based on the observation of the cancer's earliest age of onset in this subject, our purpose was to reevaluate this variant according to recent papers indicating a role of powerful modifier of the genetic penetrance...

We report a case of a Singaporean who acquired Zika virus (ZIKV) during a visit to Cuba. The infection was confirmed using molecular and serological methods. This report highlights potential drawbacks of using IgG serology for diagnosis of flavivirus infections in endemic regions. The low viremia detected during the early phase of this case resulted in low mosquito infectivity rates, suggesting the possibility of ZIKV transmission prior to clinical onset. The report also emphasizes the challenges of public health interventions for Zika fever and the importance of sustaining a low vector population to reduce the risk of arbovirus transmission in vulnerable regions...

INTRODUCTION: Although error disclosure is critical in promoting safety and patient-centered care, physicians are inconsistently trained in its practice, and few objective methods to assess competence exist. We used an immersive simulation scenario to determine whether providers with varying levels of clinical experience adhere to the disclosure safe practice guidelines when exposed to a serious adverse event simulation scenario. METHODS: This was a prospective cohort study with medical students, junior emergency medicine (EM) residents (PGY 1-2), senior EM residents (PGY 3-4), and attending EM physicians participating in a simulated case in which a scripted medication overdose resulted in an adverse event...

The authors report 2 cases of apocrine cystadenoma of the eyelid, 1 of which was studied with immunohistochemical and other special stains. While a previous report describes the tumor in a palpebro-orbital location, no other detailed descriptions of a purely eyelid location are present in the literature. Apocrine cystadenoma occupies an unusual portion of the spectrum of Moll gland tumors of the eyelid. It has no definitive clinical characteristics and may be diagnosed pathologically by hematoxylin-eosin-stained sections...
