Minimal Dose of Resistance Exercise Required to Induce Immediate Hypotension Effect in Older Adults with Hypertension:Randomized Cross-Over Controlle…

2022

To determine the optimal exercise volume to generate a hypotension response after the execution of a single strength exercise in elderly subjects with hypertension (HT), a randomized crossover design was performed. A total of 19 elderly subjects with HT performed one control session and three experimental sessions of resistance training with different volumes in a randomized order: three, six, and nine sets of 20 repetitions maximum (RM) of a single elbow flexion exercise with elastic bands. The systolic blood pressure (SBP), diastolic blood pressure (DBP), and mean heart rate (MHR) were tested at the beginning and immediately afterwards, at 30 and 60 min, and at 4, 5, and 6 h after the res…

Long-term Results After Transconjunctival Resuturing of the Scleral Flap in Hypotony Following Trabeculectomy

2013

Purpose To present the 4-year follow-up results in the surgical treatment of hypotony following trabeculectomy with mitomycin C in glaucoma patients with additional flap sutures. Design Retrospective interventional case series. Methods Since 2006, 53 patients with hypotony maculopathy attributable to overfiltration following glaucoma surgery (trabeculectomy with mitomycin C) were included in this institutional study. We were able to follow up intraocular pressure (IOP) and distance-corrected visual acuity in 33 (62%) over 4 years, whereas all were followed over 2 years. To elevate IOP, we placed tangential transconjunctival sutures through the scleral flap and connected them to the adjacent…

Brainstem evoked potentials and magnetic resonance imaging abnormalities in differential diagnosis of intracranial hypotension.

2019

Summary Objective To compare brainstem acoustic evoked potentials (BAEP) and magnetic resonance imaging (MRI) in the differential diagnosis of intracranial hypotension (IH), Chiari malformation (CM) and sensorineural hearing loss (SNHL). Methods BAEP were recorded in 18 IH, 18 CM, 20 SNHL patients and 52 controls. MRI were acquired in all IH and CM patients. Results Abnormal BAEP were observed in 94% of IH patients, in 33% of CM and 70% of SNHL patients. After recovery from IH, BAEP abnormalities disappeared. Internal auditory canal (IAC) MRI abnormalities were described in 88% of IH patients. MRI signs of IH were observed in 33–78% in IH patients, but the most frequent MRI sign was 8th ner…

Spontaneous intracranial hypotension in a patient with meningeal diverticula: a case report

2018

Objective: spontaneous intracranial hypotension (SIH) can sometime represent a puzzling clinical condition due to missing causal factors and poor response to treatment. Here we describe a SIH case where cerebrospinal fluid (CSF) leaks follow to the uncommon cause of meningeal diverticula[1]. Materials: a 54-years-old-woman who works as a caregiver came to our attention for a symptomatology characterized by heavy headache localized on the vertex that started after long lasting upright position and that improved with rest. During last two months the pain has begun costant, associated with vertigo and non responsive to rest or symptomatic drugs. Methods: the patient was admitted to our Unit an…

Comparison of different quantification methods to determine hippocampal damage after cerebral ischemia

2014

Abstract Background Experimental stroke studies use multiple techniques to evaluate histopathological damage. Unfortunately, sensitivity and reproducibility of these techniques are poorly characterized despite pivotal influence on results. Method The present study compared several quantification methods to differentiate between two severities of global cerebral ischemia and reperfusion. Male Sprague-Dawley rats were randomized to moderate (10 min) or severe (14 min) ischemia by bilateral carotid occlusion (BCAO) with hemorrhagic hypotension. Neuronal cell count was determined in hippocampus at bregma −3.14 mm and −3.8 mm on day 3 and 28 post insult by counting neurons in the whole CA1 or in…

Preoperative risk factors for postoperative delirium (POD) after urological surgery in the elderly

2011

The aim of this observational study was to investigate the occurrence of postoperative delirium (POD) in elderly patients undergoing urological surgery and to identify those factors associated with delirium. Ninety consecutive patients (81 males and 9 females; average age of 74.3 ± 0.40 years), undergoing urological surgery in University-Hospital Urological Clinic were selected. Personal, medical, cognitive and functional data, biochemical parameters, preoperative medications, conduct of surgery and anesthesia and details of hemodynamic control were collected as predictors of delirium. After surgery, the subjects were divided on the basis of delirium onset within a week observation period. …

Abnormal BAEP and internal auditory canal MRI in intracranial hypotension

2017

Intracranial hypotension (IH) is a treatable condition due to cerebrospinal fluid leak, characterised by variable clinical and MRI findings.1 Positional headache, neck stiffness, hearing changes with subdural fluid collection, enhancement of meninges, engorgement of venous structures and brain sagging are among the most frequent clinical and MRI findings. Typical abnormalities are found in 68%–85% of patients1. Hearing alterations (ranging from misperception to severe hearing loss) are known clinical symptoms of IH.1 The mechanism involves secondary perilymph depression due to patency of the cochlear aqueduct, inducing a compensatory expansion of the endolymphatic compartment, decreasing ba…

Defining Kawasaki disease and pediatric inflammatory multisystem syndrome-temporally associated to SARS-CoV-2 infection during SARS-CoV-2 epidemic in…

2021

Abstract Background There is mounting evidence on the existence of a Pediatric Inflammatory Multisystem Syndrome-temporally associated to SARS-CoV-2 infection (PIMS-TS), sharing similarities with Kawasaki Disease (KD). The main outcome of the study were to better characterize the clinical features and the treatment response of PIMS-TS and to explore its relationship with KD determining whether KD and PIMS are two distinct entities. Methods The Rheumatology Study Group of the Italian Pediatric Society launched a survey to enroll patients diagnosed with KD (Kawasaki Disease Group – KDG) or KD-like (Kawacovid Group - KCG) disease between February 1st 2020, and May 31st 2020. Demographic, clini…

Orthostatic changes in blood pressure and mortality in the elderly: The Pro.V.A study

2015

BACKGROUND An extensive, albeit contrasting literature has suggested a possible role for orthostatic hypotension as a risk factor for cardiovascular (CVD) and non-CVD mortality, while no data are available for orthostatic hypertension. We investigated whether orthostatic changes in blood pressure (BP) were associated with any increased risk of all-cause, CVD or non-CVD mortality in a group of elderly people. METHODS Two thousand seven hundred and eighty six community-dwelling older participants were followed for 4.4 years. Participants were grouped according to whether they had a drop ≤20mm Hg in systolic, or ≤10mm Hg in diastolic BP (orthostatic hypotension), an increase in mean orthostati…
