First described as a pleural neoplasm, the solitary fibrous tumor (fibrous mesothelioma) has been reported in a number of
extrapulmonary sites, including the Head-Neck region. In the Head-Neck region, it has been described in the sinonasal tract,
epiglottis, parapharyngeal, retropharyngeal spaces, parotid and infratemporal fossa. We present the second case of solitary
fibrous tumor of infratemporal fossa described in world literature. A complete excision was achieved by transmaxillary approach. 相似文献

A simple, inexpensive method using standard hematocrit capillary tubes and blood obtained from heel prick to determine E.S.R. (micro E.S.R.) in newborns is described. Normal values for 75 neonates were obtained, and the usefulness of micro ESR as an indicator of neonatal septicemia was evaluated. 相似文献

One-step SYBR Green I-based real-time RT-PCR assay for rapid detection as well as quantitation of Japanese encephalitis virus (JEV) in acute-phase patient CSF samples by targeting the NS3 gene was developed. The assay developed in this study was found to be more sensitive as compared to conventional RT-PCR. The specificity of the reported assay system was established through melting curve analysis as well as by cross-reactivity studies with related members of Flavivirus. The applicability of Real-time PCR assay for clinical diagnosis was validated with 32 suspected acute-phase CSF samples of Gorakhpur epidemic, India, 2005. The improved sensitivity of real-time RT-PCR was reflected by picking up 10 additional samples with low copy number of template in comparison to conventional RT-PCR. The quantitation of the viral load in acute-phase CSF samples was done using a standard curve obtained by plotting cycle threshold (C(t)) values versus copy numbers of the RNA template. This is the first report on the application of real-time RT-PCR for detection as well as quantitation of JEV from patient CSF samples. These findings demonstrate the potential clinical application of the reported assay as a sensitive diagnostic test for rapid and real-time detection and quantitation of JEV in acute-phase clinical samples. 相似文献

Objective: To examine the kinetics of successful nitric oxide (NO) withdrawal in vivo and in vitro.¶Design and setting: Prospective study in a university pediatric intensive care ward and research laboratory.¶Patients and materials: Nineteen patients with acute respiratory distress syndrome (ARDS) or persistent pulmonary hypertension of the newborn (PPHN). Primary porcine pulmonary artery cells in vitro.¶Interventions: NO inhalation and withdrawal in patients; exposure to NO donor sodium nitroprusside (SNP) and gaseous NO in vitro.¶Measurements and results: In patients: a slight, but significant, increase of oxygenation index (OI) from 4.57 ± 0.24 cmH2O/torr (mean ± SEM) to 4.90 ± 0.26 cmH2O/torr after withdrawal of NO (p < 0.001). Recovery of OI (4.43 ± 0.23 cmH2O/torr) 30 min after weaning, a significant drop after 4 h (3.72 ± 0.17 cmH2O/torr; p < 0.001), values restored after 12 h.¶In vitro: NO synthase (NOS) activity was significantly lower in SNP-incubated cells (20.0 ± 4.0 μm/min) than in control cells (37.6 ± 7.0 μm/min; p < 0.05). Thirty minutes after SNP withdrawal there was NOS activity of 35.8 ± 10.0 μm/min with a significant increase by 4 h (p < 0.05). No alteration of endothelial NOS (ENOS) mRNA expression by NO (Northern Blot).¶Conclusion: In patients there is a slight, but significant, reversible increase of OI after successful weaning from NO. In vitro, NO leads to a reversible decrease of ENOS activity on a post mRNA level, resembling clinical observations. 相似文献

Stable silver nanoparticles were generated in aqueous medium by amine, hydroxy and carboxylate terminated poly(amidoamine) (PAMAM) dendrimers in the absence of conventional reducing agents and light irradiation. Mechanistic studies suggest that, in spite of their lower pKa values, tertiary amines present in the dendritic structures act as the reducing agent. Dynamic light scattering and electron microscopic studies reveal that PAMAM dendrimers aggregate in presence of silver ions and the aggregation propensity plays a pivotal role in altering the size and shape of the nanoparticles generated in the dendritic milieu. The formation of metal nanoparticles with uniform size and shape by amine terminated PAMAM dendrimer is attributed to the unique aggregation propensity of amine terminated PAMAM.

This retrospective, observational study evaluated patterns of inpatient versus outpatient tumour lysis syndrome (TLS) monitoring during venetoclax ramp-up in 170 patients with chronic lymphocytic leukaemia. The primary outcome was clinical/biochemical TLS. Two clinical and four biochemical TLS occurred (4.1%). Five of the six events occurred in high-risk patients, four occurred at 20 mg dose and three at the 6-h time-point. Inpatient versus outpatient TLS rates within the high-risk subgroup were 15% and 8%. Risk category was the only predictor of TLS events in multivariate analysis. Outpatient escalation did not associate with clinically meaningful TLS events, suggesting outpatient escalation has manageable associated TLS risks, including in high-risk cohorts. These observations require confirmation in larger studies. 相似文献

Immunotherapeutic effects of a vaccine based on a saprophytic cultivable mycobacterium, Mycobacterium w in multibacillary leprosy patients 总被引:2,自引:0,他引:2

Immunotherapy with a vaccine consisting of autoclaved Mycobacterium w was given in addition to chemotherapy in 54 multibacillary, lepromin negative patients belonging to BB, BL and LL types of leprosy. Thirty-seven patients with similar types of diseases received chemotherapy and placebo injections. The 'vaccine' was repeated every 3 months. Bacterial clearance was more rapid in the vaccinated patients. Two lepromatous leprosy patients with initial bacterial index (BI) of 1.8 and 2.8 became bacteriologically negative in 1 year. One LL patient with BI of 6.0 had a BI fall to 0.16 after four doses of the vaccine. None of the LL patients belonging to placebo group during the same time period became bacteriologically negative. Rapid bacterial clearance was accompanied by distinct signs of clinical improvement. One hundred percent of BB, 85.7% of BL patients and 61.5% of LL patients converted to lepromin positivity after four doses of the vaccine. A significant number of vaccinated patients demonstrated an upgrading in skin lesions histopathologically. 相似文献

Anopheline breeding habitats were studied in two different geoclimatic zones. The vectors A. fluviatilis, A annularis and A. culicifacies breed in all types of habitats. Streams were most productive for the main vector, A. fluviatilis and breeding was intense during winter and early summer. In the rainy season, breeding occurred in terraced paddy fields. A. culicifacies were produced in large numbers in rivers in summer and in paddy fields in rainy and cold seasons. Considering the vastness of these breeding habitats, vector control measures by larviciding or any other bioenvironmental means will not be a feasible alternative even though house spraying poses serious problems in this area due to several reasons. The use of personal protection methods is suggested. 相似文献
