What are the requirements for patient-centered breast imaging? Communication preferences of mammography patients in Turkey

Abstract

We have investigated communication preferences of mammography results in 90 patients through a structured interview approach. About 81% of patients expressed that they wanted to get the results, and 18% expressed that getting the results does not help if they are incomprehensible. In patients who want to get the results, 80% preferred face-to-face interaction with physicians, whereas the others preferred other modes of communication to prevent loss of time. Majority of patients infavor of face-to-face interaction (57%) preferred both the referring physician and the radiologist. Comprehensibility and fast delivery of reports, plus direct communication with radiologists are the requirements in mammography patients while implementing patient-centered radiology.     

Percutaneous radiofrequency rhizotomy of lumbar spinal facets: The results of 46 cases

The results of percutaneous radiofrequency rhizotomy of lumbar spinal facets in 46 patients followed at least three months (mean 15 months) are reported and compared with those reported previously. Satisfactory pain relief three months after the procedure was achieved in 36.4 percent of patients without operations and in 41.7 percent of patients with operations other than fusion.No patient had previously undergone fusion.Treatment of low-back pain by using radio-frequency thermocoagulation of spinal facets is a simple, safe, and well-tolerated procedure. It can be used to relief of pain in spite of decreasing rates of success within the follow-up period.     

Pattern-reversal electroretinograms and visual evoked potentials in branch retinal vein occlusion

We recorded pattern electroretinograms and visual evoked potentials in a group of selected patients with unilateral uncomplicated branch retinal vein occlusion. To document the effects of preexisting risk factors, patients were divided into three groups: diabetes mellitus, hypertension with hyperlipidemia and no systemic disease. The transient and steady-state pattern electroretinogram and visual evoked potential amplitudes were significantly reduced and visual evoked potential peak times were delayed relative to the fellow eyes and agematched normal subjects. There was a second amplitude reduction relative to the other patient groups in both the affected and fellow eyes of the diabetes mellitus group, which was indicative of an additive effect of diabetes mellitus.Abbreviations BRVO branch retinal vein occlusion

Giant fusiform aneurysm of the vertebro-basilar artery presenting with stroke

The authors describe a case of giant fusiform aneurysm of the basilar artery presenting with ischemic symptoms. Angiography and CT revealed vertebro-basilar fusiform aneurysmal dilatation. Fusiform vertebro-basilar ancurysm is associated with various complications particularly brain stem infarction. Similar lesions in the literature are reviewed and the relationship between this clinical entity and cerebral ischemia, particularly brainstem infarction are discussed.     

The antiatherogenic effect of allicin: possible mode of action.

OBJECTIVE: Garlic (Allium sativum) has been suggested to affect several cardiovascular risk factors. Its antiatherosclerotic properties are mainly attributed to allicin that is produced upon crushing of the garlic clove. Most previous studies used various garlic preparations in which allicin levels were not well defined. In the present study, we evaluated the effects of pure allicin on atherogenesis in experimental mouse models. METHODS AND RESULTS: Daily dietary supplement of allicin, 9 mg/kg body weight, reduced the atherosclerotic plaque area by 68.9 and 56.8% in apolipoprotein E-deficient and low-density lipoprotein (LDL) receptor knockout mice, respectively, as compared with control mice. LDL isolated from allicin-treated groups was more resistant to CuSO(4)-induced oxidation ex vivo than LDL isolated from control mice. Incubation of mouse plasma with (3)H-labeled allicin showed binding of allicin to lipoproteins. By using electron spin resonance, we demonstrated reduced Cu(2+) binding to LDL following allicin treatment. LDL treatment with allicin significantly inhibited both native LDL and oxidized LDL degradation by isolated mouse macrophages. CONCLUSIONS: By using a pure allicin preparation, we were able to show that allicin may affect atherosclerosis not only by acting as an antioxidant, but also by other mechanisms, such as lipoprotein modification and inhibition of LDL uptake and degradation by macrophages.     

The role of ATP in non-adrenergic sympathetic vascular control of the nasal mucosa in anaesthetized cats and dogs.

1. In anaesthetized cats and dogs, local intra-arterial injection of noradrenaline and alpha, beta-methylene adenosine 5'-triphosphate (mATP) reduced both nasal arterial blood flow and nasal mucosal volume (a measure of capacitance vessel function). The responses to mATP were not modified by pretreatment with the adrenoceptor antagonists phentolamine and propranolol or the purinoceptor antagonist suramin. The vascular effects of noradrenaline were not altered by suramin, but were virtually abolished by adrenoceptor antagonists. 2. After adrenoceptor blockade, frequency-dependent reductions in nasal arterial blood flow with sympathetic nerve stimulation were reduced by 25 and 39% in cats and dogs, respectively; whereas the volume response was reduced by 56% in cats and 54% in dogs. The remaining non-adrenergic sympathetic nerve-evoked vascular responses were not influenced by suramin. 3. During desensitization to mATP induced by local intra-arterial infusion for 5 min, the remaining non-adrenergic nasal blood flow and volume responses to sympathetic nerve stimulation were reduced in the dog but not in the cat. 4. It is suggested that both adrenergic and non-adrenergic mechanisms are involved in the sympathetic control of the nasal mucosa vascular bed of both species. Since desensitization to mATP markedly reduces the remaining non-adrenergic nasal vasoconstriction evoked by sympathetic nerve stimulation in the dog, ATP is a possible sympathetic mediator in the nasal vascular bed in this species.
