Atmospheric cosmic rays in the South Atlantic anomaly region

To study the production and propagation of fast secondaries particles in the atmosphere, data collected during eleven quiet-time balloon flights are analysed. Comparisons of these data with those obtained in different geomagnetic rigidity regions permit to estimate the contributions of the proton and electron components in the measured intensities. Derivations of this last component in the «upward» and «downward» moving electrons fluxes indicate that in the anomaly region a fraction of these particles, produced by the primary protons, are leaving the atmosphere and will not return to the Earth. © 1991 Società Italiana di Fisica.

Dilatacao pneumatica no megaesofago avancado. Resultados do sequimento tardio

Six patients with advanced Chagas' megaesophagus with poor condition for surgical indication due to severe malnutrition and concomitant diseases were submitted to pneumatic dilatation with the aid of the endoscope. The method consists in leading the tip of the pneumatic dilatator into the cardia with the tip of the endoscope. Insufflation of the balloon must be slow and progressive with visualization of the mucosa of the cardia after insufflating of 2 pounds of air pressure. An excellent symptomatic relief was seen in the five-year follow-up but without improvement in the degree of the esophageal dilatation.

Disfunção temporária do nervo lingual após uso de máscara laríngea. Relato de caso

BACKGROUND AND OBJECTIVES: The laryngeal mask has been frequently used in Anesthesiology. Although the rate of complications with this technique is smaller than that of the endotracheal tube, it is not devoid of risks, especially in cases of difficult airways. The objective of this study was to report a case of unilateral lingual nerve damage after the use of the laryngeal mask airway. CASE REPORT: A female patient underwent a surgical procedure for removal of bilateral breast prosthesis under general, balanced anesthesia, with a size three laryngeal mask. The balloon was inflated with 30 mL of air. After the first postoperative hour, she developed decreased sensation and pain in the oropharynx and posterior two thirds of the tongue, which evolved for loss of taste in the next 24 hours. A tentative diagnosis of lingual nerve neuropraxis secondary to the use of the laryngeal mask was made. After three weeks, her symptoms subsided. CONCLUSION: Although complications after the use of the laryngeal mask airway are rare, they do occur, and neuropraxis of the lingual nerve is one of them. The diagnosis is clinical and it has a good outcome, with resolution of the symptoms within a few weeks or months. © Sociedade Brasileira de Anestesiologia, 2007.

Hysteroscopic myomectomy in a submucous fibroid near from tubal ostia and 5 mm from the serosa: A case report from the Endoscopy Service of Ginendo-RJ

This is a case report of a 27-year-old white woman, nuliparous, single, who presented a heavy menstrual flow with clots, dysmenorrhoea and anaemia. Gynaecological examination of the uterus revealed anteverted position, mobility, no pain, slight enlargement and right displacement. Magnetic resonance imaging of the pelvis showed a 29-mm submucous fibroid with intramural component more than 50%, type 2, in the posterior wall, with a 5-mm distance from serosa. In office hysteroscopy, a 30-mm submucous fibroid with an intramural component with more than 50%, type 2, near around 5 mm from left tubal ostia, classified in STEP-W submucous fibroids classification as score 6, group II, was noted. GnRH analogue was indicated for 3 months before intervention to treat anaemia. The patient was submitted to hysteroscopic myomectomy with direct mobilisation technique, with the fibroid completely removed without complications in a surgery which lasted for 52 min and 20 s. © 2008 Springer-Verlag.

Fractal dimension and Shannon's entropy analyses of the architectural complexity caused by the inflammatory reactions induced by highly crystalline polyvinyl alcohol) microspheres implanted in subcutaneous tissues of the Wistar rats

The results of the histopathological analyses after the implantation of highly crystalline PVA microspheres in subcutaneous tissues of Wistar rats are here in reported. Three different groups of PVA microparticles were systematically studied: highly crystalline, amorphous, and commercial ones. In addition to these experiments, complementary analyses of architectural complexity were performed using fractal dimension (FD), and Shannon's entropy (SE) concepts. The highly crystalline microspheres induced inflammatory reactions similar to the ones observed for the commercial ones, while the inflammatory reactions caused by the amorphous ones were less intense. Statistical analyses of the subcutaneous tissues of Wistar rats implanted with the highly crystalline microspheres resulted in FD and SE values significantly higher than the statistical parameters observed for the amorphous ones. The FD and SE parameters obtained for the subcutaneous tissues of Wistar rats implanted with crystalline and commercial microparticles were statistically similar. Briefly, the results indicated that the new highly crystalline microspheres had biocompatible behavior comparable to the commercial ones. In addition, statistical tools such as FD and SE analyses when combined with histopathological analyses can be useful tools to investigate the architectural complexity tissues caused by complex inflammatory reactions. © 2012 WILEY PERIODICALS, INC.
