Cardiac and pericardial fistulae associated with esophageal or gastric neoplasms: a literature review

Pericardial and cardiac fistulae secondary to esophageal or gastric tumors are considered exceptional. They have never been the object of a literature review. We reviewed the medical literature between 1881 and 2001, searching for all published cases of pericardial or cardiac fistulae developed from esophageal and gastric tumors or favored by the applied therapy to these tumors. The cases of metastasization, tumor spread, and neoplasic pericardial effusion without fistula were excluded. Fifty patients were identified, with one original case. More than half the cases (56%) occurred in the last 25 years. Substernal pain is the main symptom. The majority of patients present at least one condition favoring fistula formation. The auscultation of a water-wheel murmur may suggest a pneumopericardium and therefore a pericardial fistula, as does a purulent pericarditis. Arrhythmias, signs of ischemia, and hematemesis point toward a ventricular fistula. Neurological and hemostasis disorders may be suspect of an atrial lesion. Diagnosis should be made by the association of a scanner and a transit. Prognosis is bad: 76% of the patients die in the first month. Pericardial or cardiac fistulae are part of the differential diagnosis of thoracic pain in patients with esophageal or gastric tumors and in patients who were treated for these pathologies. The diagnosis must be as quick as possible. An operation (patients with a good prognosis) or the placement of a stent (patients with a bad prognosis) is the only chance of survival

Zonation for 3D aquifer characterization based on joint inversions of multimethod crosshole geophysical data

Predictive groundwater modeling requires accurate information about aquifer characteristics. Geophysical imaging is a powerful tool for delineating aquifer properties at an appropriate scale and resolution, but it suffers from problems of ambiguity. One way to overcome such limitations is to adopt a simultaneous multitechnique inversion strategy. We have developed a methodology for aquifer characterization based on structural joint inversion of multiple geophysical data sets followed by clustering to form zones and subsequent inversion for zonal parameters. Joint inversions based on cross-gradient structural constraints require less restrictive assumptions than, say, applying predefined petro-physical relationships and generally yield superior results. This approach has, for the first time, been applied to three geophysical data types in three dimensions. A classification scheme using maximum likelihood estimation is used to determine the parameters of a Gaussian mixture model that defines zonal geometries from joint-inversion tomograms. The resulting zones are used to estimate representative geophysical parameters of each zone, which are then used for field-scale petrophysical analysis. A synthetic study demonstrated how joint inversion of seismic and radar traveltimes and electrical resistance tomography (ERT) data greatly reduces misclassification of zones (down from 21.3% to 3.7%) and improves the accuracy of retrieved zonal parameters (from 1.8% to 0.3%) compared to individual inversions. We applied our scheme to a data set collected in northeastern Switzerland to delineate lithologic subunits within a gravel aquifer. The inversion models resolve three principal subhorizontal units along with some important 3D heterogeneity. Petro-physical analysis of the zonal parameters indicated approximately 30% variation in porosity within the gravel aquifer and an increasing fraction of finer sediments with depth.

Advances in Near-surface Seismology and Ground-penetrating Radar

Advances in Near-surface Seismology and Ground-penetrating Radar (SEG Geophysical Developments Series No. 15) is a collection of original papers by renowned and respected authors from around the world. Technologies used in the application of near-surface seismology and ground-penetrating radar have seen significant advances in the last several years. Both methods have benefited from new processing tools, increased computer speeds, and an expanded variety of applications. This book, divided into four sections ? ?Reviews,? ?Methodology,? ?Integrative Approaches,? and ?Case Studies? ? captures the most significant cutting-edge issues in active areas of research, unveiling truly pertinent studies that address fundamental applied problems. This collection of manuscripts grew from a core group of papers presented at a postconvention workshop, ?Advances in Near-surface Seismology and Ground-penetrating Radar,? held during the 2009 SEG Annual Meeting in Houston, Texas. This is the first cooperative publication effort between the near-surface communities of SEG, AGU, and EEGS. It will appeal to a large and diverse audience that includes researchers and practitioners inside and outside the near-surface geophysics community.

From neuroprogression to neuroprotection: implications for clinical care.

Bipolar disorder follows a staged trajectory in which persistence of illness is associated with a number of clinical features such as progressive shortening of the inter-episode interval and decreased probability of treatment response. This neuroprogressive clinical process is reflected by both progressive neuroanatomical changes and evidence of cognitive decline. The biochemical foundation of this process appears to incorporate changes in inflammatory cytokines, cortisone, neurotrophins and oxidative stress. There is a growing body of evidence to suggest that these markers may differ between the early and late stages of the disorder. The presence of a series of tangible targets raises the spectre of development of rational neuroprotective strategies, involving judicious use of current therapies and novel agents. Most of the currently used mood stabilisers share effects on oxidative stress and neurotrophins, while novel potentially neuroprotective agents are being developed. These developments need to be combined with service initiatives to maximise the opportunities for early diagnosis and intervention.
