Gene/longevity association studies at four autosomal loci (REN, THO, PARP, SOD2).

The possibility that four loci (REN, THO, PARP, SOD2) are associated with longevity was explored by comparing the genotypic pools of subjects older than 100 years with those of younger subjects matched for sex and geographic area (northern and southern Italy). The markers (all located within the respective gene) were HUMREN4; HUMTHO1; HUMPARP (gt)845nt; SOD2(C/T)401nt. In order to reduce the number of genotypes, multiallelic polymorphisms were recoded as diallelic according to allele size and frequency patterns (small: S, and large: L, alleles). A significant loss of LL homozygous genotypes was found at the THO locus in male but not in female centenarians with respect to matched controls. On the other hand no significant difference was found between case/control genotypic frequencies at REN, PARP, SOD2 loci. The latter loci therefore do not affect inter-individual variability in life expectancy (at least in terms of qualitative variants associated with the tested markers). However, the data is consistent with an association between the THO locus and longevity.

Benign edematous polysynovitis in the elderly (RS3PE syndrome).

The Authors provide an update on benign edematous polysynovitis in the elderly and propose clinical and laboratory criteria for a correct diagnosis. They also propose the use of the term "polysynovitis" rather than polyarthritis, as they think it describes the histopathological findings of the disease better. Finally, they attempt to correctly distinguish RS3PE syndrome from polymyalgia rheumatica, rheumatoid arthritis and chondrocalcinosis.

Occurrence of the Chiari network in a centenarian: echocardiographic study and magnetic resonance imaging.

An occasional finding of Chiari network in the right atrium of a centenarian patient confirms that it may be considered as a "normal anatomic variation" compatible with a long life span. The finding is documented by using echocardiographic and cardiac nuclear magnetic resonance imaging in a 102-year-old man.

Nail-fold capillaroscopy in the study of microcirculation in elderly hypertensive patients.

Hypertension represents one of the most important atherosclerotic risk factors, since it causes vascular damage both to macro- and microcirculation. Capillaroscopy is very useful to examine "in vivo" the small vessels of nail-fold and conjunctival layer of the bulb which are the most suitable areas for a morphological study of microcirculation. Capillaroscopy gives remarkable information from a clinical and diagnostic point of view, both in the diseases involving microcirculation (connective tissue disorders, diabetes) and in the evaluation of microvascular impairments in systemic diseases such as arterial hypertension. Aim of the present study was at evaluating capillaroscopic characteristics in a consecutive and non-selected series of elderly hypertensive patients and comparing the results to those observed on fundus oculi. Our study revealed the decrease of the number of capillary loops which appear thin and lengthened, in the hypertensive persons, as compared to the control group. Dilated and tortuous capillaries, arteriovenous sludge and "flea bite" juxtacapillary microhemorrhages were found more frequently in the patients with isolated systolic hypertension; they are linked to the atherosclerotic nature of that disease.

Evaluation of coronary angioplasty with autoperfusion catheter in patients aged 65 years or older.

In the period July 1991-December 1994, 120 consecutive patients underwent percutaneous transluminal coronary angioplasty (PTCA); 79% were males (mean age 70.0 +/- 5.4 years) and 21% females (mean age: 71.0 +/- 6.8 years). Patients have been divided into two groups: (i) Group A (67 patients), undergone PTCA with prolonged insufflations (longer than 20 minutes) with autoperfusion catheters (RX perfusion); and (ii) Group B (53 subjects) has been treated without autoperfusion catheters. The results show that maintenance of myocardial perfusion during angioplasty permits to increase the duration of inflations and to reduce the frequency and the extension of myocardial damages, both transmural and subendocardial. Therefore, the use of autoperfusion catheter can be recommended as a method of choice in selected lesions such as proximal traits of the left anterior descending coronary artery and the circumflex, ostial lesions of anterior descending artery, circumflex, of the right coronary artery or in PTCA of high risk in vessels with a diameter larger than 2.5 mm.

Clinical and laboratory features at onset of polymyalgia rheumatica (PMR) and elderly onset of rheumatoid arthritis in PMR-like presentation: a comparison of two groups of patients.

The differential diagnosis between polymyalgia rheumatica (PMR) and elderly onset rheumatoid arthritis (EORA) in PMR-like presentation may represent several problems at the beginning of the disease, since the patterns of these pathologies may show largely overlapping areas. In this study we examined clinical and laboratory features of 21 patients with PMR and 22 patients with EORA PMR-like presentation, to identify eventual differences between the 2 diseases. EORA PMR-like presentation occurred more frequently in males (14 men and 8 women) than PMR (6 men and 15 women) (p = 0.046). In EORA PMR-like presentation we observed higher levels of gamma-globulins (p = 0,003), immunoglobulins IgC (p =0.004), IgA (p = 0.002) and IgM (p = 0.014) than in PMR. Fever (p = 0.022), asthenia (p = 0.007) and the contemporary involvement of the shoulder and pelvic girdle (p = 0.0054) were more frequent in PMR patients than EORA PMR-like presentation patients. Moreover, the involvement of the shoulder girdle only (p =0.0054) and arthritis of the peripheral joints (p = 0.045) were more frequent in EORA PMR-like presentation than in PMR patients. The results of this preliminary study revealed different clinical and laboratory features that may offer additional help in differential diagnosis at onset of the 2 diseases.

Hypertension in a group of centenarians.

The aim of the present study was to evaluate the frequency of hypertension in a group of extremely old persons: 73 centenarians resident in Calabria were studied, aged 100-110 years, (mean age 102.95 +/- 2.0), 54 women (73.9%) and 19 men (26.1%), in the period January 1st and April 30th, 1994. All the centenarians were visited at their homes. Hypertensive centenarians were 14 (19.1%), women 12 (85.7%) and men 2 (14.3%). Even if blood pressure progressively increases with age, we have not found it in centenarians. The lesser frequency of hypertension in centenarians certainly depends on genetic and constitutional factors, but also their way of life and alimentary habits (decreased sodium intake, increase of calcium and potassium intake), as we have proven in a recent work, could be determinant. Moreover, the presence of hypertensive centenarians might mean that hypertension does not prevent to reach an age by far above the average, if it is the only risk factor.

Multidimensional evaluation in a group of centenarians.

A group of 40 Calabrian centenarians (12 males, 28 females) was studied from June 1 to December 31, 1993. Their age was ranging from 100 to 107 years (mean age: 102.3 +/- 1.8 years). Clinical evaluation was performed by recording anamnestic data, an objective examination, and by assessing cognitive performance, emotional and nutritional status, as well as functional activity. The following tests were applied: mini mental state examination (MMSE), geriatric depression scale (CDS), activity of daily living (ADL), and instrumental activity of daily living (IADL). The nutritional status was estimated by collecting answers to a questionnaire regarding nutritional habits and by measuring body weight, height and calculating body mass index (BMI). In assessment of the socio-economic conditions, the following parameters were considered: years of education, type of job, type of residence ownership, heating system used, toilet set available and the regular income. Our multidimensional evaluation has revealed, in agreement with other findings, that the Calabrian centenarians seem to be a selected population with an amazingly high activity, who overcame severe age-dependent diseases, probably because of their genetic pattern and of the environmental factors which may favor longevity.

A case of Paget's disease in an ultracentenarian subject with endoprosthesis of Moore type without cementation.

Paget's disease is an osteopathy the incidence of which increases with aging; in the 8th decade, it occurs in 11% of the population. Complications of this pathology often occur, and appear prevalently in form of basilar disease. We report a case of an ultracentenarian patient (aged 107) who suffered a cervical right femur fracture after falling in her own house at the age of 104 years. Radiological and laboratory findings revealed a mono-osseal Paget's disease of the right femur. Because of her good conditions, the patient underwent an operation of non-cemented endoprosthesis of Moore type, with a good post-operatory course and a physiokinetic therapeutic treatment. A kinesiologic evaluation was made, by measuring articular range of motion (ROM) through the neutral zero methods and evaluating the muscular strength: it showed a constantly progressive functional recovery of the lower limbs in both subjective and objective terms.

Aspects of sleep in centenarians.

Sleeping habits of 48 Calabrian centenarians (12 males, 36 females) were evaluated. Their average age was 102 +/- 1.87 years (range 100-107 years). Quantitative and qualitative aspects of sleep were recorded, such as the length of sleeping (hrs), the time of falling asleep (regular or variable) and the time of awakening (regular or variable). Moreover, we recorded and included in the global hours an eventual afternoon sleeping, during a 24-hour-period. The quality of sleeping was classified as: night sleeping, and morning sleeping; and for the subjects were grouped as short sleepers (subjects that fall asleep easily), and long sleepers (subjects with problems to fall asleep). We also considered if sleeping was uninterrupted or interrupted during the night and if the subjects followed particular habits to facilitate the sleeping (sleeping pills, alcohol, etc.). This study demonstrated that all the examined centenarians go to sleep early in the evening, have no problems in falling asleep, wake up early in the morning, take a nap in the afternoon and do not take pills before going to bed. Among the environmental factors, the quality, the quantity and the habits of sleeping might have great influence for longevity.

[Benign edematous polysynovitis in the elderly (the RS3PE syndrome). Current knowledge]. / Polisinovite edematosa benigna dell'anziano (RS3PE syndrome). Conoscenze attuali.

On the basis of their own and other researchers' knowledge, the authors describe the clinical and laboratory characteristics of benign edematous polysynovitis in the elderly. They suggest that the term polysynovitis should be used in preference to polyarthritis since it gives a better idea anatomic and pathological characteristics of RS3PE syndrome.

[Abdominal aortic aneurysm in the elderly]. / L'aneurisma dell'aorta addominale nell'anziano.

AIM: Complication-free abdominal aortic aneurysm is often asymptomatic and its diagnosis is therefore frequently coincidental. Abdominal aortic aneurysm (AAA) is often suddenly manifested during the rupture stage, resulting in the patient's death. The importance of early diagnosis is therefore clear, enabling optimal monitoring and correct management. EXPERIMENTAL DESIGN AND SUBJECTS: This retrospective study evaluated the incidence of AAA in 1304 over-65-year-olds in care. The authors examined the presence of AAA-related symptoms, risk factors and the concomitance of other pathologies. RESULTS: Four subjects were diagnosed with AAA, equivalent to 0.3% of the total population. All were male, smokers, with multidistrict atherosclerosis in association with other pathologies. CONCLUSIONS: The incidence of AAA in the population of over-65-year-olds examined was lower than that reported in the literature. This discrepancy was due to the fact that the abdominal aorta is not usually examined in clinical practice. However, the high mortality rate of AAA during rupture prompted the authors to evaluate this disorder in high-risk patients.

[Sexuality of elderly women]. / La sessualità delle donne anziane.

Physiological aging in older women it is not necessarily the cause of a change in their sexual attitudes. The organic changes, during concomitant illness, is often known to be the cause of sexual dysfunction, when present. Psychosocial factors are also very important in determining sexual dysfunction. Successful management of sexual dysfunction in older women is totally dependent on clinical history, physical examination of genitalia, personal interview. A multidisciplinary team approach is required for otimal management of sexual problems in elderly women.

[Cerebral hypoperfusion symptoms in elderly subjects with hyperkinetic and/or hypokinetic arrhythmia. Study of institutionalized and non- institutionalized patients]. / Sintomatologia da ipoperfusione cerebrale nei soggetti anziani portatori di aritmie ipercinetiche e/o ipocinetiche. Indagine su pazienti istituzionalizzati e non.

BACKGROUND: We evaluated the symptomatology caused by cerebral hypoperfusion in a group of over-65 year old hospitalized and non-patients, with hyperkinetic and hypokinetic arrhythmias. METHODS: 2441 clinical records of hospitalized and ambulatory patients at the unit of Cardiology, "Pugliese-Ciaccio" Hospital of Catanzaro between January 1st 1991 and March 31st 1995 were examined. The clinical records of those patients who had showed anamnestic episodes of syncope, lipothymia and dizziness were selected. The selected sample was made of 36 hospitalized patients and 36 ambulatory patients. The Holter-ECGs of these patients were examined. RESULTS: Six episodes of syncope (16.7%) were found in the hospitalized patients and 4 in the ambulatory patients (11.1%). Ten (27.8%) and 8 (22.2%) episodes of lipothymia, were found in the hospitalized and ambulatory patients respectively. Dizziness was found in 20 (55.5%) hospitalized and in 24 (66.6%) ambulatory patients. In all the patients the symptoms appeared during the recording and were linked to hyperkinetic arrhythmias in 22 (61.1%) hospitalized patients and in 25 (69.4%) ambulatory patients and to hypokinetic arrhythmias in 14 (39.9%) and 11 (30.5%) hospitalized and ambulatory patients. CONCLUSIONS: The present study pointed out that patients with hyperkinetic arrhythmias (both hospitalized and ambulatory) show symptoms of cerebral hypoperfusion more frequently than those with hyperkinetic arrhythmias.

[Isolated systolic hypertension in the elderly]. / L'ipertensione sistolica isolata dell'anziano.

Isolated systolic hypertension is the most common type of hypertension in the elderly. A number of trials have widely shown that it is an independent risk factor for cardiovascular morbidity and mortality. This review focuses the prevalence of isolated systolic hypertension, its pathophysiology, diagnosis and treatment. The optimal treatment strategy is to maximize reduction in systolic blood pressure and to minimize reduction in diastolic blood pressure. All classes of antihypertensive agents can be used, but calcium antagonists, ACE-inhibitors and, more recently, the angiotensin II antagonists appear to be more successful in improving large artery stiffness and therefore are especially useful in treating isolated systolic hypertension in the elderly. A careful evaluation and treatment has to be made in particular in those patients with more risk factors, in order to choose the most appropriate drug and to avoid dangerous drug-drug interactions where polypharmacy occurs.

[Prevalence and features of peptic ulcers in the elderly: a retrospective study on a not hospitalized population aged 65 or over]. / Caratteristiche e prevalenza dell'ulcera peptica nell'anziano: studio endoscopico retrospettivo su una coorte di pazienti ultrasessantacinquenni non istituzionalizzati.

BACKGROUND: The prevalence of peptic ulcer increases with aging. Data relative to peptic ulcer in the elderly are around 5.2% to 9.9%. The aim of the present study was to evaluate the prevalence and the features of peptic ulcer in a non hospitalized population aged 65 or over. METHODS: We performed, for the first time, EGDS on 706 patients with symptoms related to the superior gastroenteric tract. We considered the following risk factors: familiarity for peptic disease, habits, eventual use of FANS, infection of Hp. RESULTS: Our data show that peptic ulcer increases with aging and with physiopathological age-related changes. 114 (16.1%) patients were affected by DU; 84 (11.9%) patients were affected by GU Symptoms thereafter were not clear: epigastralgy was present in 46.4% of patients affected by GU; pyrosis, belchings, swellings, epigastric headness were present in 37.7% of patients with DU. Several times PU may arise with some complications: melena was present in 14.9% of patients with DU vs 11.9% of patients with GU, hematemesis was present in 1.7% of patients with DU vs 5.9% of patients with G.U. The most important risk factor was the infection of Hp, at was present in 71.9% patients with GU and 81.6% patients with DU FANS assumption, often with high dose, was present in 30.9% of patients with GU and 18.4% of patients with DU.

[Polydistrectual atherosclerosis in the elderly. Ischemic cardiopathy and obliterative peripheral arteriopathy of the lower limbs]. / Aterosclerosi polidistrettuale nell'anziano. Cardiopatia ischemica e arteriopatie obliteranti periferiche degli arti inferiori.

BACKGROUND: Numerous epidemiological studies have recently drawn attention to the polydistrict nature of atherosclerotic disease. In particular, it has been made clear the frequent association between coronary heart disease and peripheral arterial disease of the lower limbs. We have therefore evaluated the frequency of peripheral arterial disease in a consecutive unselected series of patients affected by coronary heart disease, over 65 and under 65. We have besides evaluated the frequency of some factors of risk for atherosclerotic disease on the subjects affected by coronary heart disease alone and in those with associated peripheral arterial disease. METHODS: We have studied 502 patients (280 males and 222 females) with coronary heart disease admitted to the II Division of General Medicine of Pugliese-Ciaccio Hospital of Catanzaro. Of the 502 patients examined, 367 (72.7%) over 65 and 137 (27.3%) under 65. Factors of risk considered were familiarity, cigarette smoking, diabetes mellitus, dyslipidosis, arterial hypertension. RESULTS AND CONCLUSIONS: Peripheral arterial disease was present in 37% of the subjects examined. In the elderly group there was a frequency of 87.6%, while in subjects under 65 the frequency was 12.4%. Symptoms of claudicatio were present in 100% of the subjects under 65 and 58.6% of the elderly subjects. Risk factors that apply with greater frequency were diabetes mellitus, arterial hypertension and smoking. The results of our study show the importance of searching for stenosis even if asymptomatic in patients with coronary heart disease, above all if elderly.

Intimal-medial thickness of the common carotid arteries and lower limbs atherosclerosis in the elderly.

BACKGROUND: In the present study, the authors consider the possible association between intimal-media thickness of the common carotid arteries and lower limb atherosclerosis, in a group of elderly patients; the authors also consider the presence of cardiovascular risk factors. METHODS: B-mode ultrasound measurement of the intimal-media thickness of the common carotid arteries was performed on 80 subjects. Lower limbs atherosclerosis was defined as the presence of intermittens claudicatio and/or ankle-arm index < 0.9. Baseline clinic examination and blood tests were performed in all subjects to consider the presence of cardiovascular risk factors. Linear regression analysis was used to assess the linear relationship between intimal-media thickness of the common carotid arteries and lower limb atherosclerosis. RESULTS: Linear regression analysis showed a statistical association between increased values of intimal-media thickness of the common carotid arteries and lower limb atherosclerosis. Sixty-four (80%) subjects presented one or more associated cardiovascular risk factors. CONCLUSIONS: The results of the the present study confirm that intimal-media thickness of the common carotid arteries is a marker for the identification of generalized atherosclerosis and may be useful for the identification of subjects, even at early stages, at risk of cardiovascular diseases.

[Stenosis of the internal carotid arteries and cardiovascular risk factors in a group of patients aged 65 years and over]. / Stenosi delle arterie carotidi interne e fattori di rischio cardiovascolari in un gruppo di pazienti ultrasessantacinquenni.

BACKGROUND: In the present study, the degree of stenosis of internal carotid arteries and the presence of cardiovascular risk factors are examined. METHODS: Two hundred patients underwent high resolution B-mode echotomography of the carotid arteries; furthermore, the presence of associated cardiovascular risk factors was considered. RESULTS: Small stenosis (< 16%) were reported in 113 (56.5%) patients; moderate stenosis (16-49%) were reported in 58 (29%) patients; severe stenosis (50-79%) were reported in 19 (9.5%) patients; subocclusive stenosis (80-99%) were reported in 2 (1%) patients; occlusions were reported in 8 (4%) patients. One hundred and fifty patients (75%) presented one or more associated cardiovascular risk factors. Hypertension was present in 122 (61%) patients; hypercholesterolemia in 43 (21.5%) patients; diabetes mellitus in 41 (20.5%) patients; 26 (13%) patients were smokers. CONCLUSIONS: According to other studies, stenosis < 50% were the most frequent (85.5%) in the subjects examined. Stenosis > or = 50% were more frequent in males than females. Hypertension was the most frequent associated cardiovascular risk factor; therefore the degree of stenosis increased with the increasing number of cardiovascular risk factors.

[Possibly ranitidine-induced autoimmune hepatitis]. / Verosimile epatite autoimmune da ranitidina.

Approved for clinical use in peptic ulcer in 1983, ranitidine competitively inhibits the interaction of histamine with H2 receptors. The incidence of adverse reactions has been low and generally minor. After reviewing the literature on hepatitis associated with ranitidine use, we report the case of a young woman, affected by multiple sclerosis, who developed severe liver injury associated with the intake of this drug. This case meets the principal criteria necessary to establish a causal relationship between the administration of a drug and the verification of an adverse reaction. The singularity of our case with respect to others reported in the literature arises from the demonstration of an anatomo-pathological picture suggestive of toxic or idiosyncratic hepatitis after the initial administration that, at rechallenge, evolved into a histologic picture of autoimmune hepatitis. We believe that physicians should be aware of the potential hepatotoxicity of ranitidine.
