Esophagopericardial fistula as a rare complication after total gastrectomy for cancer

<p>Abstract</p> <p>Background</p> <p>Esophagopericardial fistula is a rare but life-threatening complication of benign, malignant or traumatic esophageal disease. It is most commonly associated with benign etiology and carries a high mortality rate which increases with delay in diagnosis.</p> <p>Case presentation</p> <p>We present a case of an esophagopericardial fistula as a rare complication in a 53-year-old male patient, 7 months after total gastrectomy for an adenocarcinoma of the esophagogastric junction.</p> <p>Conclusion</p> <p>The prognosis of esophagopericardial fistula is poor, especially when it is associated with malignancy.</p

Control of relapsed germ cell tumor and SLE nephritis by high-dose chemotherapy and autologous hematopoietic cell transplantation

High-dose chemotherapy and hematopoietic stem cell support remains a curative treatment option for relapsed or nonresponsive germ cell tumors, and has been applied experimentally to control severe autoimmune diseases. In the present study, we report on a patient with systemic lupus erythematosus nephritis who developed a nonseminomatous germ cell tumor that relapsed after standard chemotherapy and surgery. The patient received high-dose chemotherapy supported by autologous hematopoietic cell transplantation based on its indication for relapsed germ cell tumors. Prolonged control of his relapsed germ cell tumor and systemic lupus erythematosus was attained with high-dose chemotherapy and hematopoietic stem cell support. An extensive literature review is provided alongside a detailed discussion of the aforementioned case

Combination of ICCD fast imaging and image processing techniques to probe species–specific propagation due to guided ionization waves

International audienceAbstract The present report is devoted to the study of distinct ionization waves in terms of temporally-, spatially-, and wavelength-resolved analyses. The study is based on the technique of two-dimension fast imaging. However, appropriately selected ultraviolet to near infrared optical filters are employed to capture the propagation of specific species and digital image processing techniques are applied to explore the recorded snapshots. N2(SPS), N_2^+(FNS), He I, OH(A–X), and O I, i.e., emissive neutral and ionic species, are investigated. On the other hand, the propagation of the NOγ species is studied by means of laser-induced fluorescence spectroscopy, since the light intensity due to spontaneous emission of this species was not readily detectable. Digital image processing techniques are also applied for the NOγ case. The crucial role of the above species in fields like plasma biomedicine and material processing is extensively recognized, and the present work: (i) provides gathered information on the propagation of these species within the atmospheric air; and (ii) introduces image processing algorithms to extract information which otherwise would remain hidden or uncorrelated with other plasma parameters. The present results unveil specific emission patterns due to the propagation of the N2(SPS), N_2^+(FNS), He I, OH(A–X), and O I species. The intensity patterns consist of a first peak located in the vicinity of the reactor orifice, a second peak moving away from the reactor orifice, and a continuum which couples the two peaks. However, the detailed features of each pattern depend on the type of species considered. The fluorescence of the NOγ species also suggests the division of the area downstream of the reactor orifice into two regions where distinct ionization-excitation effects take place. Propagation speeds of the species up to about 2×105 m s-1 were measured. Finally, qualitative correlation between the species propagation (as it is pronounced by the emission patterns) and the local electric field (as it was numerically calculated in a similar setup) is demonstrated
