Brain slow waves preceding time-locked visuo-motor performance.
1993
According to previous findings (Konttinen and Lyytinen, 1992), the slow brain negativity preceding the trigger pull in rifle‐shooting tends to be decreased in successful shots among experienced marksmen, whereas no such pattern is found among inexperienced subjects. This effect was interpreted as resulting mainly from optimal arousal. However, another explanation is examined here. The aim of the experiment was to investigate slow electrocortical changes associated with motor regulation and visual aiming related to shooting performance. Four variations on a shooting task were used, in which the visual and motor components were contrasted. Motor activity related to gun stabilization was found…
Urinary glycosaminoglycans in Graves' ophthalmopathy.
1990
An increased accumulation of glycosaminoglycans (GAG) in retrobulbar tissues has been reported in patients with thyroid eye disease. We examined the quantitative urinary GAG excretion in 101 patients with Graves' ophthalmopathy of different classes, 36 patients with Graves' hyperthyroidism without ophthalmopathy, 14 patients with toxic nodular goitre and 103 control subjects. Glycosaminoglycans were isolated from 24-h urine collections by precipitation with cetylpyridinium chloride and ethanol followed by photometrical quantification of hexuronic acids after reaction with carbazole. In comparison with the control group (15.8, 10.4, 21.6 mg/24 h; median, 25th, 75th percentile) a significant …
Does thyroid surgery for Graves' disease improve health-related quality of life?
2012
Abstract PURPOSE: Graves' disease can induce alterations of the psychosocial well-being that negatively influence the overall well-being of patients. Among the current treatments, surgery has limited indications, and its impact on the health-related quality of life has not been well clarified. The aim of this study was to assess the impact of surgery on the quality of life. METHODS: Fifty-seven patients who underwent total thyroidectomy for Graves' disease in our surgical unit between April 2002 and December 2009 were administered a questionnaire concerning four issues: organic alterations and clinical manifestations, neurovegetative system disturbances, impairment of daily activities, psyc…
Prevalence of myxomatous mitral valve prolapse in patients with lymphocytic thyroiditis
1995
Abstract In conclusion, given the cardiac (mitral regurgitation, endocarditis, thromboembolic complications, arrhythmic sudden death) and neurologic (cerebral embolic event) complications of the pathologic forms of MVP, 6,8 physicians should look carefully for myxomatous involvement of the mitral valve and prolapse in patients with autoimmune thyroid diseases. Patients should be monitored and prophylactic antibiotic treatment recommended when appropriate.
Lacrimal gland herniation in Graves ophthalmopathy: a simple and useful MRI biomarker of disease activity
2019
Lacrimal gland (LG) involvement in patients with Graves ophthalmopathy (GO) has been considered as a potential cause of the associated GO symptoms and different studies demonstrated the LG involvement in patients with GO than healthy controls. The aim of this study was to evaluate LG involvement, through measurement of its herniation, using a magnetic resonance imaging (MRI) index, in patients with different GO activities. Thirty-two consecutive Caucasian patients affected by GO were enrolled and grouped in group A (16 with inactive GO, CAS < 3) and B (16 with active GO, CAS ≥ 3) according to their GO activity. All patients underwent clinical-endocrinological assessment, a complete ocular e…
Autoantibodies to the islet antigen ICA69 occur in IDDM and in rheumatoid arthritis.
1995
Islet cell antigen (ICA) 69 is a newly-recognized islet cell antigen to which autoantibodies have been observed in prediabetic relatives of patients with insulin-dependent-diabetes mellitus (IDDM). Here we extend the earlier analysis of ICA69 antibodies to patients with recent-onset IDDM and to patients with other immune-mediated diseases. ICA69 antibodies were determined by Western blot using an affinity purified recombinant fusion protein of ICA69 and maltose binding protein. ICA69 antibody quantities were determined as titres using a titration curve of a standard serum as reference. Mean logarithmic ICA69 antibody titres were 3.4 (+/- 1.4) in 99 patients with acute IDDM compared to 2.8 (…
Cigarette Smoking Status at Diagnosis and Recurrence in Intermediate-risk Nonemuscle-invasive Bladder Carcinoma
2013
Objective To study the effect of smoking status at diagnosis on recurrence in intermediate-risk non–muscle-invasive bladder carcinoma treated by transurethral resection (TUR) of the bladder and early intravesical chemotherapy. Methods Tumor characteristics and smoking status were recorded in 395 patients entered in a randomized multicenter trial comparing 2 different schedules of early intravesical chemotherapy. All patients received intravesical epirubicin (80 mg/50 mL) within 6 hours after TUR, followed by 5 more weekly instillations with (arm B) or without (arm A) monthly instillations for 1 year. Smoking habit was investigated at diagnosis through a structured questionnaire. Multivariat…
The INTERPHONE study: design, epidemiological methods, and description of the study population
2007
The very rapid worldwide increase in mobile phone use in the last decade has generated considerable interest in the possible health effects of exposure to radio frequency (RF) fields. A multinational case-control study, INTERPHONE, was set-up to investigate whether mobile phone use increases the risk of cancer and, more specifically, whether the RF fields emitted by mobile phones are carcinogenic. The study focused on tumours arising in the tissues most exposed to RF fields from mobile phones: glioma, meningioma, acoustic neurinoma and parotid gland tumours. In addition to a detailed history of mobile phone use, information was collected on a number of known and potential risk factors for t…
No short-term effects of digital mobile radio telephone on the awake human electroencephalogram
1997
A recent study reported the results of an exploratory study of alterations of the quantitative sleep profile due to the effects of a digital mobile radio telephone. Rapid eye movement (REM) was suppressed, and the spectral power density in the 8–13 Hz frequency range during REM sleep was altered. The aim of the present study was to illuminate the influence of digital mobile radio telephone on the awake electroencephalogram (EEG) of healthy subjects. For this purpose, we investigated 34 male subjects in a single-blind cross-over design experiment by measuring spontaneous EEGs under closed-eyes condition from scalp positions C3 and C4 and comparing the effects of an active (0.05 mW/cm2) and a…
Are referral centers for non-muscle invasive bladder cancer compliant to EAU guidelines? A report from the vesical antiblastic therapy Italian study
2011
<i>Introduction:</i> Adherence to international guidelines is viewed as a prerequisite for optimal medical care delivery. Previously reported surveys for non-muscle-invasive bladder cancer (NMIBC) employed mailed questionnaires to urologists or patients resulting in conflicting degrees of agreement with existing guidelines. In the current study, contemporary information on the management of NMIBC was generated from a sample of Italian centers. <i>Patients and Methods:</i> Eight Italian referral centers for the treatment of NMIBC were asked to collect information relative to all consecutive patients with a histology-proven NMIBC undergoing a transurethral resection fr…
