Retinal pigment epithelial detachment, often asymptomatic is a common retinal finding. Multiple serous retinal pigment epithelial detachment especially in a female is very uncommon. We describe a case of multiple retinal pigment epithelial detachments throughout the fundus in a 51-year old female otherwise asymptomatic. Indocyanine green angiography and fundus auto fluorescence showed abnormalities with a normal systemic work-up. This is the first report of an asymptomatic patient correlating angiogram with auto fluorescence in multiple serous retinal pigment epithelial detachments. 相似文献
The potent orexigenic peptide neuropeptide Y (NPY) has been considered as a possible endogenous ligand for a subpopulation of sigma receptors (SigR). However, their mutual interaction with reference to feeding behavior remains poorly understood. In the present study, we explored the possible interaction between sigma1 receptors (Sig1R) agonist, pentazocine, and NPY on food intake in satiated rats. While pentazocine dose-dependently reduced the food intake, NPY significantly increased it at 2, 4 and 6 h post injection time points. In combination studies, pretreatment with NPY (0.1 nmol/rat, intra-PVN) normalized the inhibitory effect of pentazocine (60 μg/rat, intra-PVN) on food intake. Similarly, pre-treatment with pentazocine (30 μg/rat, intra-PVN) significantly antagonized the orexigenic effect of NPY (0.5 and 1.0 nmol/rat, intra-PVN). Moreover, pentazocine treatment decreased NPY immunoreactivity in arcuate (ARC), paraventricular (PVN), dorsomedial (DMH) and ventromedial (VMH) nuclei of hypothalamus. However, no change was observed in lateral hypothalamus (LH). Study implicates the reduced NPY immunoreactivity for the anorectic effect observed following pentazocine injections. Therefore, the concomitant activation of the NPYergic system along with the Sig1R agonist treatment may serve a useful purpose in the management of the unwanted side effects related to energy homeostasis. 相似文献
Sinus of Valsalva aneurysm is a rare congenital cardiac abnormality and is usually diagnosed when it ruptures. An asymptomatic 55‐year‐old male of unruptured sinus of Valsalva aneurysm of noncoronary cusp was on medical follow‐up. At 2‐year follow‐up, there was thrombus formation in the aneurysm, mimicking right atrium tumor on 2D transthoracic echocardiography. Cardiac computed tomography showed filling defect in the aneurysm suggestive of thrombus. Considering the high risk of systemic emboli surgery was performed, and aneurysm was repaired with Dacron patch. 相似文献
Abstract: Background: Fetal movement counting may improve timely identification of decreased fetal activity and thereby contribute to prevent adverse pregnancy outcomes, but it may also contribute to maternal concern. This study aimed to test whether fetal movement counting increased maternal concern. Methods: In a multicenter, controlled trial 1,013 women with a singleton pregnancy were randomly assigned either to perform daily fetal movement counting from pregnancy week 28 or to follow standard Norwegian antenatal care where fetal movement counting is not encouraged. The primary outcome was maternal concern, measured by the Cambridge Worry Scale. Analysis was by intention-to-treat. Results: The means and SDs on Cambridge Worry Scale scores were 0.77 (0.55) and 0.90 (0.62) for the intervention and the control groups, respectively, a mean difference between the groups of 0.14 (95% CI: 0.06–0.21, p < 0.001). Decreased fetal activity was of concern to 433 women once or more during pregnancy, 45 and 42 percent in the intervention and control groups, respectively (relative risk = 1.1, 95% CI: 0.9–1.2). Seventy-nine percent of the women responded favorably to the use of counting charts. Conclusions: Women who performed fetal movement counting in the third trimester reported less concern than those in the control group. The frequency of maternal report of concern about decreased fetal activity was similar between the groups. Most women considered the use of a counting chart to be positive.

Purpose: The purpose of the study is to report the prognostic factors and outcomes of vitrectomy (PPV) with silicone oil tamponade in rhegmatogenous retinal detachment (RRD) secondary to acute retinal necrosis (ARN).
Methods: This retrospective, non-randomized, interventional comparative study included 38 eyes of 38 patients. All cases underwent PPV with silicone oil tamponade. The main outcome measure was improvement of final visual acuity relative to the presenting visual acuity and factors affecting the same Group A included eyes with favorable vision of 20/400 or better and Group B included the others.
Results: Group A included 16 eyes (42.10%), group B included 22 eyes (57.89%). In Group A 2 eyes out of 16 (12.5%) and in Group B 12 eyes out of 22 (54.54%) had RRD at presentation (p = 0.02, 95% CI for the difference 7.88–65.78%). The time interval between first presentation and development of RRD in Group A was 30.94 ± 38.8 days (median 30 days) whereas that in Group B was 10.81 ± 11.73 days (median 8 days) (p = 0.02). The odds of visual improvement post-vitrectomy when RRD occurred later was 8.4 (p = 0.01, 95% CI 1.53–46.1). The usage of systemic steroids (odds 5.2, p = 0.03, 95% CI 1.14–23.54) and oral valacyclovir (odds 4.33, p = 0.04, 95% CI 1.05–17.84) were associated with odds favoring a good visual outcome. Recurrent RRD was noted in 3/16 eyes (18.75%) in Group A and 13/22 eyes (59.09%) in Group B (p = 0.03).
Conclusion: Delayed occurrence of RRD after ARN is a good prognostic factor. Usage of systemic steroids and oral valacylocvir are associated with a favorable visual outcome when started before the onset of RRD. 相似文献
We describe the case of a patient who developed torsade de pointes during temporary pacemaker insertion after administration of intravenous erythromycin. The case highlights the dangers of administering drugs that prolong the QT interval in patients with complete atrioventricular block, and we discuss the underlying pathophysiological recipe that can lead to a potential arrhythmic disaster. 相似文献
Lipid-lowering and antioxidant activities of a hydroalcoholic extract of Cyperus scariosus Linn. root(HCS) were evaluated in guinea pigs fed with a high cholesterol diet. Serum lipid profile(total cholesterol, triglycerides, LDL-C, VLDL-C, and HDL-C), atherogenic indices and serum enzymes(ALT, AST, ALP, LDH, and CK-MB) were performed in each group at 0 days and at the end of 60 days. Histological study of liver and kidney was done in groups 1, 2, 5, 6 and 7. The total phenolic and flavonoid content in HCS and its antioxidant activity were evaluated by the DPPH assay. Both doses of HCS decreased serum lipid profile and atherogenic indices(P 〈 0.05). HCS has lipid lowering, immunosuppressive and antioxidant properties, and mays have value in atherosclerosis prevention. The higher dose of HCS also reduced serum AST, ALP, and LDH levels and rosuvastatin increased AST and ALP levels(P 〈 0.05). Histology of the liver showed decreased lipid accumulation and improvement in hepatocytes in HCStreated animals. The antioxidant activity of HCS may be responsible for its lipid lowering and cytoprotective action. HCS had significant lipid lowering and antioxidant activity, which; may be due to the phenolic compounds. HCS may be a safe and cost effective alternative to current statin therapy for patients with dyslipidaemia. 相似文献
People with co-occurring behavioral and physical conditions receive poorer care through traditional health care services. One solution has been to integrate behavioral and physical care services. This study assesses efforts to integrate behavioral health and primary care services in New York. Semi-structured interviews were conducted with 52 professionals in either group or individual settings. We aimed to identify factors which facilitate or hinder integration for people with serious mental illness and how these factors inter-relate. Content analysis identified structural, process, organizational (“internal”) and contextual (“external”) themes that were relevant to integration of care. Network analysis delineated the interactions between these. We show that effective integration does not advance along a single continuum from minimally to fully integrated care but along several, parallel pathways reliant upon consequential factors that aid or hinder one another. 相似文献
