Purpose
Endovascular treatment with mechanical thrombectomy devices demonstrated high recanalization rates but functional outcome did not correlate with high rates of recanalization obtained. Patient selection prior to the endovascular treatment is very important in the final outcome of the patient. The primary aim of our study was to evaluate the prognostic value of posterior circulation Alberta Stroke Program Early CT Score (pc-ASPECTS) and Pons-Midbrain Index (PMI) scores in patients with Basilar Artery Occlusion (BAO) treated with successful angiographic recanalization after mechanical thrombectomy.Methods
Retrospective single-center study including 18 patients between 2008 and 2013 who had acute basilar artery occlusion managed with endovascular treatment within 24 hours from symptoms onset and with successful angiographic recanalization. The patients were initially classified into two groups according to clinical outcome and mortality at 90 days. For analysis we also divided patients into groups based on pc-ASPECTS (≥8vs.< 8) and PMI (≥3vs.< 3) on non-contrast CT (NCCT) and CT Angiography Source Images (CTASI). Imaging data were correlated to clinical outcome and mortality rate.Results
CTASI pc-ASPECTS, dichotomized at < 8 versus≥8, was associated with a favorable outcome (RR: 2.6; 95% CI: 1.3-5.2) and a reduced risk of death (RR: 6.5: 95% CI: 7.8-23.3). All patients that survived and were functionally independent had pc-ASPECTS score≥8. None of the 5 patients with CTASI pc-ASPECTS score less than 8 survived.Conclusion
PC-ASPECTS on CTASI is helpful for predicting functional outcome after BAO recanalization with endovascular treatment. These results should be validated in a randomized controlled trial in order to decide whether or not to treat a patient with BAO. 相似文献2.

This paper studies all cases affected by 5 parotiditis from January to September 1986 (1767 cases) and 1987 (124 cases), as well as all patients with rubella reported in the same period in 1986 (584 cases) and 1987 (5 cases) in the province of Pinar del Río. The rise in the incidence of the two diseases with an annual basis per 100,000 population during 1986 in the different municipalities is emphasized. The overtly downward trend of these two diseases in 1987 after the administration of the triple viral vaccine--93% for mumps and 99.15% for rubella--is discussed. It was found that these two diseases affected more often school children (5-14 years). It was found that these two diseases are not frequent under the first year of life (76.4 and 120.1 cases per 100,000 population respectively). The percentage of vaccine effectiveness was documented--97.4% for parotiditis and 100% for rubella. 相似文献

The authors present three cases of vein of Galen aneurysmal malformations (VGAMs) diagnosed in infancy and submitted by the referring teams for stereotactic radiosurgery as the initial therapy (therapeutic doses ranging between 20–25 Gy and 40–50 Gy to the peak dose). After the conventional follow-up of 18–24 months, no change could be detected in the angioarchitecture of the lesions. All three cases were then referred for endovascular treatment and underwent embolization by the transarterial route using liquid adhesives (N-butyl cyanoacrylate). This resulted in complete anatomical exclusion of the lesion. Regardless of the theoretical efficiency of radiosurgery in the management of brain arteriovenous malformations, the present authors believe that transarterial embolization remains the treatment of choice in VGAMs. It offers a high rate of morphological cure and the best chances for normal neurocognitive development. The time required by radiosurgery to achieve a significant result is too long for developing and maturing brain and may not prevent the negative effects of the lesion, mainly in regard to hemo- and hydrodynamic disorders (atrophy, subcortical calcifications, etc.) created by the VGAM, thus leading to irreversible mental retardation. 相似文献

A review of the literature on gender identity disorders is integrated with a case study presentation of a psychiatrically
disturbed nineteen-year-old transvestite youth. Accommodations and interventions made both with this patient and in the day
care program for psychiatrically disturbed youths that allowed him to live at home and be maintained despite severe pathology
are discussed.

Summary Pyomyositis is an acute bacterial infection of striated muscle. It is common in the tropics, but rarely reported in temperate climates. We present two cases in patients with the acquired immune deficiency syndrome (AIDS), one an active homosexual, and one an intravenous drug user. A brief review of the clinical findings and diagnostic procedures is included. We conclude that pyomyositis should be included in the list of locations of pyogenic infections that can occur in AIDS patients.
Spontane Pyomyositis und AIDS: ein seltenes Zusammentreffen
Zusammenfassung Die Pyomyositis ist eine akute bakterielle Infektion der quergestreiften Muskulatur. Im Gegensatz zu den Tropen, wo sie häufig auftritt, wird die Pyomyositis in gemäßigten Klimazonen nur selten beobachtet. Wir stellen zwei Patienten mit Pyomyositis und AIDS vor: der eine Patient ist Homosexueller, der andere intravenös drogenabhängig. Klinische Befunde und diagnostisches Vorgehen werden kurz dargestellt. Nach unserer Meinung sollte die Pyomyositis in die Liste pyogener Infektionslokalisationen bei AIDS-Patienten eingereiht werden.相似文献

A 32-year old woman, with endocarditis caused by Streptococcus mitis, and systolic murmur is presented. The Doppler examination was found a systolic gradient of 150 mmHg. Aortography showed a multiple membranous supravalvular aortic stenosis, with aneurysmal dilatation of the left main coronary artery and circumflex artery, associated with bicuspid aortic valve and mild aortic insufficiency. The patient died suddenly by cardiac arrest in stand by to cardiac surgery. Anatomic comprobation was not possible. The coronary artery anomalies associated with the supravalvular aortic stenosis syndrome are reviewed. 相似文献

Summary: Cell–cell and cell–matrix interactions are of critical importance in immunobiology. Leukocytes make extensive use of a specialized repertoire of receptors to mediate such processes. Among these receptors, integrins are known to be of crucial importance. This review deals with the central role of integrins and their counterreceptors during the establishment of leukocyte–endothelium contacts, interstitial migration, and final encounter with antigen-presenting cells to develop an appropriate immune response. Particularly, we have addressed the molecular events occurring during these sequential processes, leading to the dynamic subcellular redistribution of adhesion receptors and the reorganization of the actin cytoskeleton, which is reflected in changes in cytoarchitecture, including leukocyte polarization, endothelial docking structure formation, or immune synapse organization. The roles of signaling and structural actin cytoskeleton-associated proteins and organized membrane microdomains in the regulation of receptor adhesiveness are also discussed. 相似文献

To investigate the effects on infants of the use of marijuana and cocaine during pregnancy and to compare the importance of urine assays with that of interviews in ascertaining drug use, we prospectively studied 1226 mothers, recruited from a general prenatal clinic, and their infants. On the basis of either interviews or urine assays conducted prenatally or post partum, 27 percent of the subjects had used marijuana during pregnancy and 18 percent had used cocaine. When only positive urine assays were considered, the corresponding values were 16 percent and 9 percent, respectively. When potentially confounding variables were controlled for in the analysis, the infants whose mothers had positive urine assays for marijuana, as compared with the infants whose mothers were negative according to both interviews and urine assays, had a 79-g decrease in birth weight (P = 0.04) and a 0.5-cm decrement in length (P = 0.02). Women who had positive assays for cocaine, as compared with nonusers, had infants with a 93-g decrease in birth weight (P = 0.07), a 0.7-cm decrement in length (P = 0.01), and a 0.43-cm-smaller head circumference (P = 0.01). To compare our findings with those of other investigators who did not use urine assays, we repeated the analyses, considering only self-reported use of marijuana (23 percent) and cocaine (13 percent). There were no significant associations between such use as determined by interviews alone and any of the measures of outcome. We conclude that the use of marijuana or cocaine during pregnancy is associated with impaired fetal growth and that measuring a biologic marker of such use is important to demonstrate the association. 相似文献

Candida dubliniensis is a yeast species closely related to Candida albicans, but in contrast to C. albicans, limited information is available on the virulence factors of this important fungal pathogen. The objective of the present study was to determine if this species was able to evoke an adaptive response to oxidants. C. dubliniensis, treated with a low concentration of either H(2)O(2) or methyl viologen (a superoxide generating agent), mounts an adaptive response that results in increased survival against lethal doses of both oxidants. This response was characterized by the induction of enzymes with known antioxidant function. C. dubliniensis strains were less resistant to oxidants than C. albicans, displaying higher susceptibility to their toxic effects. The adaptive response described here might be responsible, among other factors, for the ability of this pathogen to cause infections in individuals with impaired immunity. 相似文献
