T he ability to probe the base of a wound to periosteum or bone (the " probe-to-bone " test) is increasingly used to indicate the likelihood of underlying osteomyelitis. The original study (1) reported sensitivity, specificity, and positive (PPV) and negative (NPV) predictive values of 66, 85, 89, and 56%, respectively. However, this work has been(More)
Some analogy exists between cognitive impairment in hypoxemic patients with chronic obstructive pulmonary disease (COPD) and Alzheimer's disease (AD). We purposed to verify whether the analogy extends to the cerebral perfusion pattern. Ten normal subjects, 15 COPD patients with and 18 without hypoxemia, and 15 patients with mild AD matched for age and(More)
This study aimed to define the verbal memory profiles of very old normal subjects and subjects with Alzheimer's Disease, and to identify verbal memory indices having the highest discriminant power. Forty-three old normal subjects (mean age = 71 years, SD = 3, range = 65-75), 39 very old normal subjects (mean age = 81 years, SD = 4, range = 76-87), and 45(More)
Congestive heart failure (CHF) has been proposed as a possible cause of cognitive dysfunction but only a few studies have directly assessed cognitive performance in CHF. The aim of the present study was to compare the cognitive patterns of patients with CHF and patients having cardiovascular diseases uncomplicated by CHF (no-CHF group). In a multicenter(More)
BACKGROUND Adverse drug reactions (ADRs) are common causes of in-hospital complications for elderly people. The purpose of the present study is to verify whether concealed renal insufficiency, that is, reduction of the estimated glomerular filtration rate (GFR) in people with normal serum creatinine levels, is a risk factor for ADRs in elderly hospitalized(More)
Cognitive dysfunction, mainly memory impairment, characterizes congestive heart failure (CHF). Aim of this study was to verify whether: (1) CHF has differential effects on primary and secondary memory; (2) memory dysfunction can be diagnosed by a screening instrument. In a multicenter study we enrolled 369 patients with stable CHF who underwent a structured(More)
We studied 54 patients with hypoxemic chronic obstructive pulmonary disease (COPD). The Mini Mental State Examination and the Mental Deterioration Battery were used for neuropsychological assessment. Heart rate variability (HRV) was assessed based on 24-h Holter ECG recording. Mann-Whitney test was used to compare HRV parameters of patients performing(More)
BACKGROUND Endothelium-derived nitric oxide (NO) mediates the arterial dilation following a flow increase (i.e. flow-mediated dilation, FMD), easily assessed in the brachial artery. NO is also involved in cerebral hemodynamics and it is supposed to trigger vascular changes occurring during migraine. This study aimed at investigating whether migraine(More)
BACKGROUND Chronic obstructive pulmonary disease (COPD) affects independence and survival in the general population, but it is unknown to which extent this conclusion applies to elderly people with mild disease. The aim of this study was to verify whether mild COPD, defined according to different classification systems (ATS/ERS, BTS, GOLD) impacts(More)
BACKGROUND Glomerular filtration rate (GFR) is directly associated with survival. However, the prognostic significance of GFR might be different according to the formula used to estimate it. We aimed at comparing the association between GFR estimated using three different formulas and 1-year survival in elderly patients discharged from acute care hospitals.(More)
