Systemic non‐biologic agents have long been in clinical use in medicine – often with considerable efficacy, albeit with some adverse effects – as with all medications. With the advent of biologic agents, all of which currently are restricted to systemic use, there is a growing need to ensure which agents have the better therapeutic ratio. The non‐biologic agents (NBAs) include a range of agents, most especially the corticosteroids (corticosteroids). This study reviews the corticosteroids in systemic use in management of orofacial mucocutaneous diseases; subsequent studies discuss corticosteroid‐sparing agents used in the management of orofacial diseases, such as calcineurin inhibitors used to produce immunosuppression; purine synthetase inhibitors; and cytotoxic and other immunomodulatory agents. 相似文献

This study has shown that glycosaminoglycans added to the culture medium may affect neurite formation in SH-SY5Y neuroblastoma cells. The most effective glycosaminoglycans are heparin and COS 8, a preparation with low anticoagulant activity. Promotion of neuritogenesis was remarkable at concentrations as low as 10-8 and 10-10. When added at 10-4 M both agents are inhibitory. Chondroitin-4 sulfate, dermatan sulfate, and heparan sulfate were also effective, the doses required were, however, as high as 10-4 M for promoting and 10-4 M for inhibiting neuritogenesis. Thereby low doses of glycosaminoglycans promote, while higher doses inhibit neurite formation. The effects were observed when neuritogenesis was promoted in neuroblastoma cultures either by deprivation of serum or by addition of retinoic acid, in the former case neuritogenesis occurred within 48 hr; in the latter, in 14 days. PC12 pheochromocytoma cells neuritogenesis was triggered by adding NGF to the culture medium. We have also observed that glycosaminoglycan supplementation to the culture medium lowered the quantity of NGF required to form neurites by PC12 cells. Glycosaminoglycans at the dose of 10-8 M allow the formation of PC12 neurites even in presence of 1 ng/ml NGF, a dose that normally is ineffective. © 1996 Wiley-Liss, Inc. 相似文献

Background To evaluate the efficacy of intra-alveolar administration of dexamethasone 4 mg in the control of edema, trismus, and pain resulting from the extraction of impacted lower third molars and the drug permeability through the oral mucosa by in silico prediction.Material and Methods The randomized, double-blind, split-mouth clinical trial included patients who had both impacted lower third molars in equivalent positions. Hemiarches were divided into control side when dexamethasone was administered orally and experimental side when dexamethasone was administered using the intra-alveolar route. Patients were evaluated considering edema, trismus, and pain. The permeability of dexamethasone through the oral mucosa was assessed by in silico prediction. Student’s t-test was selected for comparative analysis of edema and trismus, and the chi-square test analyzed the distribution of postoperative pain between the sides.Results There were no significant differences between the routes of administration in measuring symptoms between the pre and postoperative times (p>0.05). In silico prediction suggested that dexamethasone molecular characteristics facilitate intra-alveolar administration.Conclusions Intra-alveolar administration had similar efficacy to oral administration in controlling symptoms of post-surgical inflammation of impacted lower third molars. Key words:Molar, third, tooth, impacted, oral surgical procedures, dexamethasone. 相似文献

The association between hypocalcemia and heart failure is rare. There are few reported cases in the literature of this association, which is termed hypocalcemic cardiomyopathy.We report the case of a 61-year-old woman with no relevant medical history, admitted for progressively worsening exertional dyspnea, orthopnea and edema of the lower limbs for a previous month. Physical examination showed diffuse muscle spasms, with no signs of latent tetany.Further investigation revealed ionized calcium 0.54 mmol/l (normal 1.12-1.30), phosphorus 9.8 mg/dl, parathyroid hormone <2.5 pg/ml and CK >3000 U/l, with normal thyroid function. The electrocardiogram showed long QT interval and a pattern of left ventricular overload, and myocardial biomarkers were negative. The echocardiogram revealed regional wall motion abnormalities, coronary angiography was normal and a cranial CT scan detected calcification of basal ganglia and white matter.She started diuretic and calcium replacement therapy which resulted in complete clinical recovery, with no need for heart failure therapy after normalization of serum calcium. 相似文献

Comparative in vitro activities of six new fluoroquinolones and other oral antimicrobial agents against Campylobacter pylori. 总被引:2,自引:1,他引:2 下载免费PDF全文
The in vitro susceptibilities of 56 clinical isolates of Campylobacter pylori to six new fluoroquinolones and other oral antimicrobial agents were determined by an agar dilution technique. Ciprofloxacin was the most active of the fluoroquinolones (MIC for 90% of strains tested [MIC90], 0.05 microgram/ml). Other fluoroquinolones had variable activities, although most isolates were moderately susceptible to fleroxacin (MIC90, 4 micrograms/ml) and lomefloxacin (MIC90, 4 micrograms/ml). 相似文献

Efficient, wide-scale testing for SARS-CoV-2 is crucial for monitoring the incidence of the infection in the community. The gold standard for COVID-19 diagnosis is the molecular analysis of epithelial secretions from the upper respiratory system captured by nasopharyngeal (NP) or oropharyngeal swabs. Given the ease of collection, saliva has been proposed as a possible substitute to support testing at the population level. Here, we used a novel saliva collection device designed to favour the safe and correct acquisition of the sample, as well as the processivity of the downstream molecular analysis. We tested 1003 nasopharyngeal swabs and paired saliva samples self-collected by individuals recruited at a public drive-through testing facility. An overall moderate concordance (68%) between the two tests was found, with evidence that neither system can diagnose the infection in 100% of the cases. While the two methods performed equally well in symptomatic individuals, their discordance was mainly restricted to samples from convalescent subjects. The saliva test was at least as effective as NP swabs in asymptomatic individuals recruited for contact tracing. Our study describes a testing strategy of self-collected saliva samples, which is reliable for wide-scale COVID-19 screening in the community and is particularly effective for contact tracing. 相似文献
