Patients with carotid atherosclerosis can present with ophthalmic symptoms. These symptoms and signs can be due to retinal emboli, hypoperfusion of the retina and choroid, opening up of collateral channels, or chronic hypoperfusion of the globe (ocular ischemic syndrome). These pathological mechanisms can produce many interesting signs and a careful history can bring out important past symptoms pointing toward the carotid as the source of the patient''s presenting symptom. Such patients are at high risk for an ischemic stroke, especially in the subsequent few days following their first acute symptom. It is important for clinicians to be familiar with these ophthalmic symptoms and signs caused by carotid atherosclerosis for making an early diagnosis and to take appropriate measures to prevent a stroke. This review elaborates the clinical features, importance, and implications of various ophthalmic symptoms and signs resulting from atherosclerotic carotid artery disease. 相似文献

OBJECTIVE: The authors assessed the prevalence of domestic violence among patients examined in the emergency service of a general hospital. They compared the socio-demographic status and psychiatric comorbidity of victims of domestic violence and other patients. METHOD: An assessment was made on 126 consecutive patients received by the emergency service of Bichat-Claude Bernard hospital (Paris, France). Assessment of domestic violence was made through the use of a specific questionnaire. RESULTS: The prevalence rate of domestic violence was 18% among patients examined by the emergency service. Thirty-five percent of the cases were physical violence, 22% sexual violence, 17% psychological violence and 26% multiple forms of domestic violence. Domestic violence had been going on for less than 1 month in only one case. In 74% of the cases, violence lasted for more than 1 year. No differences were found in terms of socio-demographic characteristics (age, marital status, rate of unemployment, sex ratio) and psychiatric comorbidity between victims of domestic violence and others. CONCLUSION: Patients seen in an emergency service must be identified as a population at risk for domestic violence (18%). These situations can be identified only by a systematic assessment using a standardized questionnaire. 相似文献

Introduction
Despite widespread administration of programmed death receptor 1 (PD-1) pathway inhibitors among individuals with NSCLC, little is known about the safety and activity of these agents among human immunodeficiency virus (HIV) – infected patients since this population has largely been excluded from immunotherapy clinical trials.Methods
Here, we describe seven patients with metastatic NSCLC and HIV infection who were treated with PD-1 inhibitors nivolumab (two cases) or pembrolizumab (five cases with three in the first-line setting).Results
Partial responses to immune checkpoint inhibitors were observed in three of seven cases. Among four patients with a programmed death ligand-1 tumor proportion score ≥50%, three partial responses were observed. All patients received antiretroviral therapy while on anti–PD-1 treatment. None of the patients experienced grade 3 or 4 immune-related adverse events or immune reconstitution inflammatory syndrome, and none required PD-1 inhibitor dose interruption or discontinuation due to toxicity.Conclusions
Nivolumab and pembrolizumab can be safe and effective among patients with NSCLC and HIV. Larger studies will be needed to determine the overall safety and efficacy of immune checkpoint inhibitors among cancer patients with HIV. 相似文献106.

Metformin is an antihyperglycemic drug that is widely prescribed for type 2 diabetes mellitus and is currently being investigated for the treatment of nonalcoholic steatohepatitis (NASH). NASH is known to alter hepatic membrane transporter expression and drug disposition similarly in humans and rodent models of NASH. Metformin is almost exclusively eliminated through the kidney primarily through active secretion mediated by Oct1, Oct2, and Mate1. The purpose of this study was to determine how NASH affects kidney transporter expression and metformin pharmacokinetics. A single oral dose of [14C]metformin was administered to C57BL/6J (wild type [WT]) and diabetic ob/ob mice fed either a control diet or a methionine- and choline-deficient (MCD) diet. Metformin plasma concentrations were slightly increased in the WT/MCD and ob/control groups, whereas plasma concentrations were 4.8-fold higher in ob/MCD mice compared with WT/control. The MCD diet significantly increased plasma half-life and mean residence time and correspondingly decreased oral clearance in both genotypes. These changes in disposition were caused by ob/ob- and MCD diet–specific decreases in the kidney mRNA expression of Oct2 and Mate1, whereas Oct1 mRNA expression was only decreased in ob/MCD mice. These results indicate that the diabetic ob/ob genotype and the MCD disease model alter kidney transporter expression and alter the pharmacokinetics of metformin, potentially increasing the risk of drug toxicity. 相似文献

The effect of tendon excursion velocity on longitudinal median nerve displacement: Differences between carpal tunnel syndrome patients and controls 下载免费PDF全文

The subsynovial connective tissue (SSCT) is a viscoelastic structure connecting the median nerve (MN) and the flexor tendons in the carpal tunnel. Increased strain rates increases stiffness in viscoelastic tissues, and thereby its capacity to transfer shear load. Therefore, tendon excursion velocity may impact the MN displacement. In carpal tunnel syndrome (CTS) the SSCT is fibrotic and may be ruptured, and this may affect MN motion. In this study, ultrasonography was performed on 14 wrists of healthy controls and 25 wrists of CTS patients during controlled finger motions performed at three different velocities. Longitudinal MN and tendon excursion were assessed using a custom speckle tracking algorithm and compared across the three different velocities. CTS patients exhibited significantly less MN motion than controls (p ≤ 0.002). While in general, MN displacement increased with increasing tendon excursion velocity (p ≤ 0.031). These findings are consistent with current knowledge of SSCT mechanics in CTS, in which in some patients the fibrotic SSCT appears to have ruptured from the tendon surface. © 2015 Orthopaedic Research Society.
