    Notes: Abstract A multicentre observational study was conducted in order to detect the major clinical diagnosis found in 761 patients with Raynaud's phenomenon (RP) attending 50 Italian centres for rheumatology and internal medicine. Systemic sclerosis was the most frequent condition associated with secondary RP, occurring in 216 (28.4%) patients. The other most frequent clinical diagnoses included systemic lupus erythematosus (52 cases: 6.8%) and rheumatoid arthritis (38 cases: 5%). Other RP-related diseases (hypertension, Sjögren's syndrome, mixed connective tissue disease, undifferentiated connective tissue disease, fibromyalgia, carpal tunnel syndrome, cryoglobulinemia, dermatopolymyositis, vasculitis, thoracic outlet syndrome, hypothyroidism, diabetes mellitus) occurred in less than 5% of cases. A total of 130 (48%) out of 268 patients with primary RP showed one or more clinical features indicating a fairly high risk of evolving into fully established systemic sclerosis. None of these patients fulfilled the ACR criteria for systemic sclerosis. This study shows that over 50% of patients with RP attending 50 Italian centres for rheumatology and internal medicine had a connective tissue disease. The large number of patients with primary RP and isolated clinical features of connective tissue disease indicates that more efforts should be focused on developing new criteria for the classification of RP.

    Determinants of bone mineral density in immobilization: A study on hemiplegic patients (1996)

    Notes: Abstract Osteoporosis that develops during immobli-zation is a severe condition that confers increased risk of fractures with their burden of mortality and disability. The aim of this study was to investigate the determinants of immobilization osteoporosis. As a model of this condition we studied hemiplegic subjects, measuring bone mineral density in the paralyzed lower limb as compared with the non-paralyzed one. In spite of the limits related to the loss of nervous stimulation, this model offers the advantage of a proper control for the complex genetic and environmental cofactors involved. We examined 48 hemiplegic subjects (31 men, 17 women in menopause) admitted consecutively over a 9-month period. Mean length of immobilization was 10.9 months for men (range 1–48 months) and 7.8 months for women (range 1–40 months). The average time since menopause was 14.9 years (range 1.7–23.9 years). For each subject the following were performed: questionnaire, medical examination, anthropometric measurements, evaluation of the scores for spasticity and for lower limb motor capacity in order to account for the different degrees of disability among patients. Bone mineral density was measured using dual-energy X-ray absorptiometry (DXA) at both femoral necks. For each patient we defined a percentage difference in bone loss between the paralyzed and non-paralyzed limb. Regression coefficient were calculated by multiple logistic regression. There was significant bone loss in the paralyzed limb in both sexes, accounting for up to 6.3% in women. Multiple regression analysis showed that the degree of bone loss depends significantly and directly on the length of immobilization, even when controlling for age and sex in the regression model (R=0.193,p=0.034). However, when time since menopause was included in the regression model, with length of immobility as a covariate, it was the only significant determinant of bone loss (R=0.312,p=0.039). No additional factors were observed among men. No differences were shown with regard to anthropometric measurements or functional scores. Length of immobilization accounts only for a small fraction of bone loss, which does not exceed 5% of the total variance. Our data show that postmenopausal women should be considered at highest risk for osteoporosis in cases of immobility and that different factors, other than length of immobility, might come into play in determining bone loss in this condition.

    Urodynamic analysis of voiding dysfunction in orthotopic ileal neobladder (1999)
    Springer
    World journal of urology 17 (1999), S. 285-289

    ISSN: 1433-8726
    Keywords: Key words Studer neobladder ; Orthotopic ileal reservoir ; Urodynamic investigation

    Topics: Medicine
    Notes: Abstract We examined the urodynamics, particularly voiding dysfunction, in patients with a neobladder. Free uroflowmetry, pressure-flow study, and voiding cystourethrography were performed in 22 patients (mean age 65 years) at a mean of 21 months after ileal neobladder substitution. The results of free uroflowmetry were used to divide patients into two groups: the good voiders and the poor. Daytime continence was achieved in all patients, while 10 (45%) had nighttime continence. To void 250 ml urine the good voiders strained 2 ± 1.5 times, and the poor voiders 6 ± 5 times. The neobladder neck was at the most caudal portion of the reservoir in good voiders, and there was wide funneling. In the group with poor emptying ability, the outlet was not located at the most dependent position. The principal factors for ensuring good voiding function in neobladder patients are the ability to perform effective straining and the location of the neobladder neck.

    The crust and upper mantle structure beneath southern Italy by earthquakes and DSS data (1981)

    Notes: Abstract This paper describes a travel—time analysis performed for the Italian seismic stations, in particular those operating in southern Italy, in order to study the crust and upper mantle properties in the region. Average P-wave residuals of teleseisms in the distance range 30°–95° with respect to Jeffreys-Bullen tables, at thirteen permanent and temporary stations of southern Italy, are coherent with a high velocity zone beneath Calabria and northern Sicily and low velocity material in the mantle beneath the Eolian Islands. Travel—time residuals from Tyrrhenian intermediate earthquakes show a high velocity structure which extends in a NW direction from a depth of at least 200 km down to 450 km. A damped least-squares inversion applied to DSS data confirms the existence of low velocity zones in the crust beneath the Eolian Islands, at 8–12 km depth, that agrees with previous results and with the lack of S waves from local earthquakes.

    Subduction zone geometry and stress patterns in the tyrrhenian sea (1985)

    Notes: Abstract Joint hypocenter determination is performed for intermediate and deep earthquakes of the Tyrrhenian Sea region. This analysis allowed us to obtain a catalogue of 70 well-located events in this peculiar Benioff zone, which is characterized by quite low seismic activity, compared to the Pacific deep earthquake regions. The method used for the analysis is that ofFrohlich (1979), a variant of the successive approximation technique, which allows use of a great number of events and stations but saves computer memory. The results show a spoon-shaped Benioff zone, dipping NW in the Tyrrhenian Sea to 500km depth. 32 reliable fault-plane solutions have been determined using these new earthquake locations, confirming the predominance of down-dip compression in the central part of the slab and more complex motion along the borders of the zone, as previously suggested byGasparini et al. (1982).

    A fluid-filled fracture as possible mechanism of ground deformation at Phlegraean Fields, Italy (1984)

    Notes: Abstract Two uplift episodes have recently been recorded at Phlegraean Fields, a volcanic region near Naples (south-central Italy). The first episode occurred in 1970 and lasted up to 1972; the second has begun at the end of 1982 and is still in progress. An attempt to model the ground deformations which occurred during the 1970–1972 event is made in this paper. The source has been assumed to be a two-dimensional fluid-filled fracture, similar to a sill. A good fit with experimental data has been obtained for a short (1–2 km long) shallow (3 km deep) source and a driving pressure ranging from 60 to 210 bars. Rigidity values have been fixed at 3.5–4.0 × 1010 c.g.s., with Poisson ratio equal to 0.3. This solution which differs from previous approaches byMogi (1958) andWalsh andDecker (1971) is non-unique, but the present results are in good agreement with observed horizontal and vertical displacements. Notwithstanding the oversimplification made in assuming a homogeneous elastic semi-infinite medium, the predicted stress field seems to be in agreement with the fault-plane solutions and the pattern of epicenters determined for the uplift-seismic swarm episode that is still in progress.

    Notes: Abstract Cancer mortality was analysed in 3282 elderly subjects aged ≥ 65 years from 2 cohorts of general population having different life-style patterns. They took part in the CASTEL (CArdiovascular STudy in the ELderly), a 12-year lasting prospective Italian study. The aim of the present analysis was to identify the items able to influence cancer mortality. A biochemical profile and a questionnaire on lifestyle were collected. Continuous items were averaged and compared with analysis of variance, frequencies with the Pearson's ϰ2 test. Mortality was recorded yearly for 12 years from the Registrar's Office and causes of death double-checked by consulting medical case sheets and family doctors' files. The influence of items on mortality was evaluated with the Cox multivariate analysis. Relative risk (RR) of each item was adjusted for confounders. Age, gender, tobacco smoking, the presence of respiratory symptoms, low body mass index in males, serum alanine transaminase (ALT) and alkaline phosphatase (ALP), as well as the town of residence, were powerful predictors of cancer mortality. In the entire population, 12-year overall mortality was 49.4%, cardiovascular 22.8%, and neoplastic 11%; the latter was higher in males than in females (15.7% vs. 7.9%, p 〈 0.00001). In subjects with respiratory symptoms neoplastic mortality was 11.6% (RR: 1.47) vs. 9.7% in those without symptoms (p 〈 0.01). Subjects with very low cholesterol (≤ 178 mg/dl), those with high uric acid (≥ 8.7 mg/dl) and males with low body mass index (≤ 22.7 kg/m2) has an increased risk of cancer mortality. RR of cancer mortality increased with increasing ALT or ALP. It was ∼1 in those having ALT and ALP between 9 and 41.2U/I, 1.41 in those exceeding this latter level and 〈 1 in those below 9U/I. RR of ALP had a similar trend, the best protective cut-off value being 〈106 and the worst one 〉 177U/I. When both serum enzymes were simultaneously raised, RR of cancer mortality increased to 2.84.
