Intracranial pressure and pressure volume relation in patients with subarachnoid haemorrhage (SAH)
1978
The development of the intracranial pressure after a subarachnoid haemorrhage was evaluated in 21 patients. A statistically significant relation between the intracranial pressure and the neurological findings was found, whereas vasospasms did not influence the intracranial pressure. In patients in a clinically critical condition, rhythmic pressure waves of a frequency of 1/minute were repeatedly observed.
Idiopathic intracranial hypertension: orbital MRI
1995
The case is reported of a patient with idiopathic intracranial hypertension examined with magnetic resonance imaging. Marked enhancement of the optic nerve heads was found, which might be related to blood-retinal barrier breakdown related to a sudden rise in intracranial cerebrospinal fluid pressure.
Factors Related to the Occurrence of Microalbuminuria During Antihypertensive Treatment in Essential Hypertension
2002
The objective of the study was to assess the factors related to the occurrence of microalbuminuria during the follow-up of a young adult group with essential hypertension that had not been previously treated. Normo-albuminuric essential hypertensives, <50 years old, who had not been previously treated with antihypertensive drugs and who did not have diabetes mellitus were included. After the initial evaluation, patients were treated using only nonpharmacological measures (n=62), β-blockers (n=38), ACE inhibitors (n=64), calcium channel blockers (n=8), and several classes (n=15). Measurements were taken for office blood pressure, biochemical profile, and 24-hour urinary albumin excretion…
Wound Care Management: impact on outcomes of nursing care
2017
SCOPO: Valutare la gestione del wound-care all’interno di un Policlinico di Roma. METODO: Studio osservazionale, diviso in due fasi, attraverso l’analisi di 301 cartelle infermieristiche di pazienti ricoverati presso il Policlinico con lesioni da pressione già in atto o sviluppate successivamente al ricovero. 151 sono state analizzate direttamente nei reparti di degenza nel biennio 2013-2014. 150 sono state reperite in versione digitale e si riferiscono al triennio 2010-2012. RISULTATI: La documentazione infermieristica relativa alle lesioni da pressione risulta completa, come da protocollo ospedaliero, mediamente nel 4%. Le schede Push Tool e Braden sono presenti nelle cartelle rispettivam…
Subcortical ischaemic changes in young hypertensive patients: frequency, effect on cognitive performance and relationship with markers of endothelial…
2007
Information on subcortical ischaemic changes (SIC) in young hypertensive patients is scarce. We evaluated the frequency of SIC at magnetic resonance imaging (MRI), the possible effect on cognition of these patients, and the role of plasma markers known as indicators of endothelial and haemostatic activation. Inclusion criteria were age <or=54 years, hypertension for at least 2 years and absence of cerebrovascular disease or other conditions possibly related to SIC. Patients with SIC at MRI and two control groups (matched for age, sex and education) of hypertensive patients without SIC and non-hypertensive healthy subjects underwent an extensive neuropsychological examination and evaluation …
Pulse pressure amplification and its determinants
2015
Background. Pulse pressure (PP) amplification expressed as the peripheral-to-central PP ratio has gained importance in the assessment of cardiovascular phenotypes and cardiovascular risk. The aim of the present study was to assess the relationship between PP amplification, large vessel parameters and peripheral blood pressure (BP) to gain insights into the amplification phenomenon. Methods. Peripheral BP, central BP and carotid-femoral pulse wave velocity (cfPWV) were assessed using the OMRON M6, SphygmoCor and Complior devices, respectively, in 741 adults attending the hypertension outpatient clinic. Analysis of covariance, partial correlations and multiple linear regression models were pe…
Tissue elastance and fluid conduction in normotensive and hypertensive intracerebral mass haematomas.
1988
This is an investigation into the prognostic factors of 117 patients with spontaneous normo- and hypertensive intracerebral haematomas, supported by animal experiments. Preserved tissue elastance and fluid conduction enables the drainage of intrinsic haematoma serum into the CSF spaces in normotensive patients, who showed an increased extension of a perifocal hypodensity in the CT. Arterial hypertension decreased the possibility of fluid resolution. Our experimental studies showed that in hypertensive cases the serum remained trapped in the haematoma, which explains the small hypodense area around the haematoma in most of the hypertensive cases. If as an exception in hypertensives of perifo…
Overview of ambulatory blood pressure monitoring in childhood and pregnancy.
2001
Despite the fact that the study and applicability of ambulatory blood pressure in children and pregnant women share characteristics which limit the potential development of knowledge for their use, advances produced in the last few years provided the present knowledge regarding the significance and the potential use of ambulatory blood pressure in children and in the pregnant women. In children ambulatory blood pressure monitoring is useful for the diagnosis of mild hypertensives, assessment of refractory hypertension, therapeutic trials with antihypertensive drugs, and clinical investigation when BP is one of the parameters to be taken into account and/or when subtle BP abnormalities are t…
Job absenteeism and arterial hypertension: results of a hypertension control program.
1992
This study reports the findings of one of the stages of a programme for the detection and control of arterial hypertension, started in I980 in an automobile company with a workforce of 9,782. In the initial screening, 522 hypertensive males were found using epidemiological criteria and 206 of these fulfilled the criteria of definite hypertension. The objective of this study consisted of evaluating, 9 years after the start of the program, the indirect cost in terms of the reduction in the morbidity indicator-temporary work incapacity (TWI). Analysis is based on a comparison of the prevalence of hypertension in the population when the program was begun (6%) and in 1989 (9.8%). It can be obser…
Odontostomatological therapeutic possibilities in patients with sleep apnea
2009
Objectives: To evaluate the different therapeutic possibilities for treating Sleep Apnea/ Hypoapnea Syndrome (SAHS), as well as the effectiveness of such treatments, and to evaluate the epidemiological and clinical aspects of this syndrome. Study design: We carried out a meta-analytical, observational and retrospective study by selecting a total of 13 articles, which provided a sample size of 642 diagnosed cases of SAHS. Results: SAHS was more prevalent among males (88.7%) and the average age of diagnosis was 49.75 years old. In the majority of cases, these patients were found to be overweight, with an average body mass index of 28.32 Kg/ m². The average apnea / hypoapnea index was 31.64 ap…
