Effect of repetition of Semont's manoeuvre on benign paroxysmal positional vertigo of posterior semicircular canal.

If Semont's liberating manoeuvre does not lead to relief of symptoms in benign paroxysmal positional vertigo of posterior semicircular canal after the first session, it can be repeated once again, in refractory cases, whilst symptomatic patients after second manoeuvre require rehabilitation therapy Repeating Semont's manoeuvre several times has proven to progressively increase the percentage of cured patients or it may convert posterior semicircular canal forms to typical incomplete or lateral semicircular canal forms, hence requiring other manoeuvres to achieve vertigo resolution. Aim of study was to assess the effect of liberating manoeuvres repeated up to 4 times and to establish possible passages from one canal to the other during manoeuvres as well as percentage of cases refractory to this therapy, who would then need rehabilitation. Benign paroxysmal positional vertigo was diagnosed in 448 cases of whom 344 (76.8%) of the posterior semicircular canal, 20 (0.45%) the incomplete form of the posterior semicircular canal, 20 (0.45%) subjective positional vertigo and 74 of the lateral semicircular canal (4.2%). Right side was affected in 58.4% of cases, left in 34.5%, and bilateral in 7.1%. All 344 patients underwent Semont's liberating manoeuvre (1st manoeuvre) with first control after 48 hours: if symptoms (typical, atypical nystagmus or paroxysmal vertigo evoked by Dix-Hallpike's manoeuvre) persisted, Semont's liberating manoeuvre was repeated (2nd manoeuvre). In presence of lateral semicircular canal benign paroxysmal positional vertigo conversion, Lempert's manoeuvre was performed instead. Second control was performed after 48 hours and in cases of persistent typical, atypical or lateral semicircular canal nystagmus 3rd manoeuvre was performed. After further 48 hours, third control was carried out: symptomatic patients with typical forms were submitted to 4th manoeuvre, while typical incomplete forms or forms of the lateral semicircular canal underwent Lempert's manoeuvre. In conclusion, symptoms disappeared after 1st manoeuvre in 61.6% of cases; further manoeuvres, carried out in view of possible changes in semeiology of vertigo, increased the percentage of cured patients to 82.5% after the 2nd, 90.7% after 3rd and 94.1% after the 4th. Repeated positioning manoeuvres in benign paroxysmal positional vertigo led to a progressive increase in percentage of cured vertigo, at the same time, allowing detection of those cases converted to multicanal pathology, hence offering the possibility to proceed with appropriate liberating manoeuvres.

Features of excessive alcohol drinking in older adults distinctively captured by behavioral and biological screening instruments. An epidemiological study.

The entire > or =65-year-old population living in a small Italian town, where alcohol use is almost ubiquitous, was assessed with a frequency-quantity questionnaire for alcohol intake and with two screening instruments for alcohol problems, the CAGE questionnaire and the MCV-gammaGT test. Aim of the study was to assess whether these instruments identify different subsets of subjects with alcohol problems. Of the 649 participants, 19.1% were at-risk drinkers (average intake > 40 g/day in men and > 20 g/day in women). Both the screening instruments were positive in only a minority of participants. Of the 377 drinkers, 53 gave > or =1 affirmative response to the CAGE questionnaire, whereas 24 had a positive MCV-gammaGT test. The concordance between positive CAGE questionnaire and MCV-gammaGT test was limited to seven subjects (kappa = 0.10), and these tests identified subjects who differed for several health and psychosocial characteristics. Participants aged > or =75 years drank less, but had similar prevalence of CAGE and MCV-gammaGT positive markers as compared to younger participants. In conclusion, excessive drinking is common in the elderly. Screening tests based on behavioral and biological markers identify two different sets of subjects with possible alcohol problems. This might indicate the opportunity to use these instruments in conjunction.

[Computerized modification of Fukuda test]. / Rivisitazione del test di Fukuda mediante misure di elaborazione computerizzate.

OBJECTIVES: To study a new method to apply to Fukuda test in order to overcome the interpretational difficulty associated with a subjective evaluation of the exam. MATERIALS AND METHODS: During the exam, the patient wears a specially-designed headpiece, with a band at the back fitted with a sensor accommodating both a gyroscope and a bi-axial accelerometer. When asked to step in place, he does so in the Romberg position, eyes closed, successively rotating his head to the right and to the left. RESULTS: On analyzing the data obtained through the laterality variable (right/left oscillation) and time variable, it resulted that the difference between the averages referring to the laterality variable of right-handed and left-handed subjects was statistically significant (P = 0.001), while the difference between the averages of the time variable was not. CONCLUSIONS: To be able to propose an evaluation of the clinical validity of the test, further research must be carried out on pathological subjects, thus verifying the applicability of the method to the full.

Cardiopulmonary resuscitation of older, inhospital patients: immediate efficacy and long-term outcome.

OBJECTIVE: To determine the independent effect of advancing age on prognosis after cardiopulmonary resuscitation (CPR). DESIGN AND SETTING: Retrospective analysis of clinical records of patients who received CPR in a geriatric department equipped with an intensive care unit. PATIENTS: A total of 245 patients (146 men, 99 women; mean age, 70+/-11 yrs) received CPR. Of these, 221 had a cardiocirculatory arrest (CA) in the intensive care unit and 24 had a CA in the general ward of the department. Acute myocardial infarction was the most frequent admission diagnosis. INTERVENTIONS: CPR according to standard guidelines in all cases. MEASUREMENTS AND MAIN RESULTS: Immediate, short-term (hospital discharge), and long-term (median follow-up, 31.5 months; range, <1-124 months) survival. Older patients had a lower immediate survival (<70 yrs [72/137] 52.6% vs. > or =70 yrs [43/108] 39.4%; p < .05) and, less frequently, ventricular tachycardia/ fibrillation (VT/VF) as a cause of CA. VT/VF bore the lowest immediate mortality rate (19/104; 18.3%) as compared with asystole/complete heart block (66/102; 64.7%) or pulseless electrical activity (40/49; 81.6%; p < .001). Acute myocardial infarction, acute heart failure, hypotension, and occurrence of CA in the intensive care unit were also univariate predictors of unfavorable, immediate prognosis. However, in a multiple logistic analysis model, the mechanism of CA (asystole/complete heart block or pulseless electrical activity vs. VT/VF), acute myocardial infarction, heart failure, and hypotension were independent predictors of unfavorable immediate prognosis, whereas advancing age was not. Similarly, after initially successful CPR, short-term survival was independently associated with acute myocardial infarction, hypotension before CA, initial rhythm at CA, and need for mechanical ventilatory support after CPR, but not with age. Longterm survival (42 patients; 17.2% of the original cohort; median survival, 32 months) was also independent of age, whereas it was negatively associated with heart failure. CONCLUSION: Immediate, short- and long-term prognosis after in hospital CPR is independent of age, at least when possible confounders are simultaneously taken into account.

Heart failure in community-dwelling older persons: aims, design and adherence rate of the ICARe Dicomano project: an epidemiologic study. Insufficienza Cardiaca negli Anziani Residenti a Dicomano.

BACKGROUND: The prevalence of heart failure (HF) increases with age, and HF is a major cause of disability and mortality in older persons. Detection of HF in epidemiological studies has relied on criteria validated only in young and middle-age adults, and, therefore, may prove inadequate in older subjects, because they do not take into account the pathophysiologic and clinical peculiarities of HF in old age. Thus, the true prevalence of HF in the older general population remains uncertain and has probably been underestimated in previous studies. Moreover, the mechanism and the extent by which HF hinders physical functioning in older people has not been fully elucidated. OBJECTIVES: This paper describes the design of the ICARe study, carried out in an older home-dwelling population to collect data about: (1) the sensitivity and specificity of diagnostic criteria used previously in epidemiological studies of HF; (2) the prevalence of the different pathophysiologic forms of HF; and (3) the impact of HF on overall health status, and on physical functioning, in the absence or presence of chronic comorbidity. DESIGN AND SETTING: This was a cross-sectional survey. Eligible were all community-dwelling persons aged 65 years or older recorded in the Registry Office of Dicomano, a small town nearby Florence (Italy). All the domains of multidimensional geriatric assessment were explored through different phases of the study (home interview, laboratory testing, geriatric visit) that comprised an extensive cardiopulmonary instrumental assessment including: color Doppler echocardiography, echotomography of the carotid arteries used in an original method to determine arterial compliance, and bell spirometry. Presence of major chronic conditions was ascertained by predefined, standard algorithms that were based largely on clinical examination. RESULTS: There were 864 older persons eligible for the ICARe study. Even with a substantial decline from home interview (91.2%) to the cardiopulmonary study (71.1%), the adherence rate remained high throughout the study, and the population examined was fairly representative of the original eligible population. Thus, we believe that the data collected in this study offer a unique opportunity to assess the validity of the diagnostic clinical criteria for HF in the general older population, to identify the pathophysiology underlying the syndrome, and to investigate the relationship between HF, comorbidity, and disability.
