Factors associated with climacteric symptoms in women around menopause attending menopause clinics in Italy.
OBJECTIVE: To obtain data on correlates of climacteric symptoms in women around menopause attending menopause clinics in Italy. METHODS: Since 1997 a large cross sectional study has been conducted on the characteristics of women around menopause attending a network of first level menopause outpatient's clinics in Italy. A total of 66,501 (mean age 54.4 years) women are considered in the present paper. RESULTS: The odds ratios of moderate and severe hot flashes/night sweats were lower in more educated women and (for severe symptoms only) in women reporting regular physical activity. Depression, difficulty to sleep, forgetfulness and irritability tended to be less frequent in more educated women and (depression only) in women reporting regular physical activity. Parous women reported more frequently these symptoms. CONCLUSIONS: This large study confirms in Southern European population that low education, body mass index and low physical activity are associated with climacteric symptoms. Parous women are at greater risk of psychological symptoms.

Donor characteristics can influence transplant activities and the access to transplant for some age groups.
In recent years Italy has experienced a remarkable increase in organ donation and transplant rates for kidney transplantation. The organ donation rate has placed Italy among the European leaders, but a careful comparative evaluation of Italian and international registries data demonstrates that renal transplantations have not shared the same significant growth. In a decisive way donor characteristics have influenced not only the number of renal transplantations, but also the access to transplant for some age groups. We investigated the probability of transplantation from different age groups using the Kaplan-Meier method and the log-rank test. The 7-year probability of transplant was 72% for the 15 to 45 age group, 85.7% for the 46 to 55 age group, and 88.5% for the over 55 years group (P = .0029). Ethical considerations suggest new approaches of innovative promotion of living donor transplants and a revision of organ allocation criteria.

Immunosuppression in renal transplantation: viral diseases and chronic allograft nephropathy.
Chronic allograft dysfunction after renal transplantation can be ascribed to different causes, among which are viral infections. The aim of this work was to show the various ways by which different kinds of viruses affect transplant structure and function. Polyoma virus is an example of viruses directly affecting the kidney because of a specific tropism to the uroepitelial cells. Cytomegalovirus (CMV) has been chosen both because of the frequency of this infection and because CMV (as other viruses) can produce transplant vascular sclerosis. Finally, we describe hepatitis C virus (HCV) because of its capacity to induce renal lesions independently from chronic allograft nephropathy. Indeed HCV is likely to determine immunologically mediated nephritis in the transplanted kidney as well in the native one.

Neonatal size of low socio-economic status Black and White term births in Albany County, NYS.
Birth weight has long been a focus of study by epidemiologists and human biologists, because it reflects the quality of the intrauterine environment and may be used as a predictor of future growth and development. Comparisons of Black and White neonates in the USA have consistently shown differences in birth weight. Confounding variables are a major problem in any such investigation, especially socio-economic status which is highly correlated with race in the USA. This study was distinctive in the sampling of one socio-economic stratum (low income), and the use of five anthropometric measures in addition to birth weight. The goals of this study were as follows: to determine if there were differences in body size and body composition at birth in Black and White neonates of low socio-economic status (SES), and to investigate what variables might account for any observed variability. The sample consisted of full term Black and White neonates of low SES (n = 323) born in Albany, NY (1986-1997). Birth weight, length, head and arm circumference, and subscapular and triceps skinfolds were compared. Race was determined through maternal self-identification. White neonates were significantly larger than Black neonates in birth weight, length and head circumference. Among female neonates none of the anthropometric dimensions differed between Blacks and Whites. Among male neonates, Whites were significantly larger than Blacks in birth weight, length, head and arm circumferences. Principal components analysis reduced the six anthropometric dimensions to two summary measures: body size and composition. When controlling for social and biological variables, race and sex were significant predictors of body composition, but not body size. Interpretation of results and possible causal relationships are discussed.

Identification of a conserved N-capping box important for the structural autonomy of the prion alpha 3-helix: the disease associated D202N mutation destabilizes the helical conformation.
Peptides corresponding to three alpha helices present in the C-terminal region of the human prion protein have been synthesized and their structural autonomy analyzed by circular dichroism (CD) and NMR spectroscopy. The results obtained indicate that the protein fragment corresponding to the alpha 3-helix, in contrast to alpha 1 and alpha 2 peptides, shows a complete structural autonomy. The chemical shifts values found for NH and CHalpha resonance of the isolated alpha 3 peptide, formed by 30 aminoacid residues, were markedly and surprisingly similar to the corresponding values of the alpha 3-helix in the protein. The structural autonomy of the alpha 3-helix is profoundly determined by the presence of the conserved capping box and, in part, by the ionic bond formed between Glu200 and Lys204. On the basis of these observations a novel PrP consensus pattern, centered on the alpha 3-helix region, has been defined. The data indicate that this autonomous and highly conserved region of the PrPc likely plays a critical role in folding and stability. This gives an explanation of why many of pathogenic mutations occur in this part of the molecule, sharing relevant effects on the overall protein conformation. In particular the D202N capping mutation almost completely destabilizes the isolated alpha 3 peptide. While it is well known that the D202N substitution is associated with a GSS disease, the possible structural basis of this fatal pathology has never been investigated. We propose that a lower alpha 3-helical propensity leading to a major destabilization of the PrPc molecule initiates the pathogenic process associated with D202N capping mutation.

[The main problems of occupational health in Navarra, 1994-1996].
In 1996 the Navarra Occupational Health Institute, an autonomous technical organization that integrates the functions and means related to occupational health matters, drew up the Occupational Health Diagnosis of Navarra, which is a region characterised by its important industrial sector and its high proportion of small and medium size companies. The results emphasise the high accident rate in the construction sector, the constant increase of professional diseases through "fatigue of tendon pods", as well as the importance of osteo-muscular processes as a cause of temporary and permanent disability. Forty sentinel occupational tumors, mainly mesothelioma, and 27 Obligatory Statement Diseases of occupational origin, mainly brucellosis, were identified in a period of seven years and three years, respectively. Verification was made of a lack of systematised information about population exposure to occupational risks, a scarce development of medical surveillance of exposed workers, and a lack of information about the incidence of occupational injuries in self-employed workers.

Dehydroepiandrosterone inhibits the growth of DMBA-induced rat mammary carcinoma via the androgen receptor.
Dehydroepiandrosterone (DHEA) exerts opposite effects on the growth of mammary carcinoma. A stimulatory effect is observed in absence of estrogens, due to interaction of DHEA metabolite(s) with the estrogen receptor (ER); by contrast, in presence of estrogens DHEA inhibits tumor growth. The mechanism underlying the latter DHEA effect, which might be related to activation of the androgen receptor (AR), is poorly understood. Focusing on this point, we measured over a 20 days period the areas of DMBA-induced mammary tumors in rats given DHEA and/or the anti-androgen flutamide (FLU). Results show that DHEA inhibitory effect on the growth of mammary carcinoma is no longer observed when the ARs are blocked by FLU. Data are consistent with an involvement of ARs in the inhibitory effect of DHEA.

[Epidemiology and risk factors in osteoarthritis: literature review data from "OASIS" study].
Ostheoarthritis (OA) is a social disease characterized by pain, inflammation and stiffness due to an involvement of articular cartilage, soft tissues and bone. OA is the most common rheumatic disease, every age can be affected but prevalence increases dramatically with age with a greater incidence in subjects between 40 and 50 years of age. Hip OA has an important correlation with weight, genetic factors, sex, previous traumas, occupational factors and age. People older than 35 have a prevalence of hip OA of 10.8% that becomes 35.4% in people older than 85. Knee OA has a great correlation with weight ,life style and physical activity. An Italian study demonstrated that the prevalence of this kind of OA is highest in subjects older than 65 that becomes 44% in people older than 80. In this report we explain the results of a study conducted in the South of Italy called the OstheoArtrithis Southern Italy Study (OASIS) that involved 456 doctors and 1782 patients of three different regions. The mean age of these patients was 66.3 years and we evaluated prevalence of hip, knee, hand and spine OA and correlated it to sex, age, weight and BMI. We also evaluated what kind of drugs were used for these patients. Knee OA is the most common subset of OA, the one that requires the highest number of examinations and the one that causes the greatest disability. The most common used drugs are Fans and Coxibs. Condroprotectors were not used much, probably because they are not considered to be very effective.

Hypertensive vascular crisis secondary to chronic total renal artery occlusion.
We have reviewed thirty-three cases of accelerated hypertension associated with chronic total renal artery occlusion. During the process of progressive narrowing of the arterial lumen until complete occlusion, an exceptionally elevated blood pressure occurs when a critical reduction of renal blood flow is attained. Then the patient presents one or more of the following clinical manifestations: III-IV grade KWB retinal changes, hypertensive encephalopathy including convulsive attacks, stroke, heart failure, renal insufficiency. We have called this clinical event 'hypertensive vascular crisis'. Mostly in older patients an actual or anamnestic vascular crisis makes a diagnosis of chronic total renal artery occlusion highly probable.

Chronobiology of blood pressure.
The chronobiology of blood pressure is a useful tool for examining serial data to quantify the dynamics of variability. The implications and applications for diagnosis and therapy are discussed, with clinical examples. The chronobiological patterns of hypertension are described. Chronobiology can make a real contribution to the prevention of disease. Chronobiology helps diagnose circadian hyper-amplitude-tension (CHAT), a condition in which excessive circadian BP amplitude precedes chronic established hypertension.

[Comparison of methodologies to reach 'dry weight'].
BACKGROUND: In clinical practice it is very difficult to determine a final weight that is the expression of normovolemia. In hemodialysis (HD), 'dry weight' is conventionally defined as the weight reached by the patient at the end of that hemodialytic session when the maximum quantity of fluids is removed without inducing any symptomatology. The determination of dry weight has been based on the application of clinical criteria. The use of artificial kidneys with blood volume (BV) sensors has allowed the determination of dry weight through the interpretation of changes in the intradialytic BV curve. Conventional bioimpedance analysis (BIA), or better, the vectorial BIA (BIVA) is a new method for determining dry weight. This study evaluated the use of the above-mentioned method for the proper governing of dry weight. PATIENTS AND METHODS: Twenty HD patients were observed for 4 weeks. In the 1st week, the clinical symptomatology of every patient was monitored during both HD sessions and interdialytic periods. During the 2nd week, intradialytic changes in the BV of each patient were observed on artificial kidneys. In the 3rd week, a cardiologist monitored patients before and after hemodialytic treatments. In the 4th week, the body composition of each patient was analyzed through bioelectrical bioimpedance. RESULTS: Patients, who had clinically shown symptoms of hyperhydration, to the contrary at BIA were dehydrated. Conversely, patients who had dehydration symptoms presented signs of hyperhydration at BIA. CONCLUSIONS: BIVA is the diagnostic instrument that more accurately demonstrates the hydration state of hemodialytic patients. It contributes in defining dry weight more efficiently.

[Evaluation of nutritional status in a group of patients undergoing CAPD].
The onset of a protein-energy malnutrition represents a real risk for patients on CAPD. In order to verify the nutritional status and the effectiveness of the dietetic surveillance in preventing this complication, dietary intake, anthropometric measurements and biochemical parameters were monitored in 46 patients (27 males, 19 females, mean age: 58.7 +/- 14.8 years), suffering from ESRF and treated with CAPD, for a total observation period of 1731.67 months (mean: 37.64 +/- 25.17 months). The mean glucose concentration in the dialysate was 2.00 +/- 0.36 g/dl, the glucose reabsorption from dialysate per kg of ideal body weight (kg-IBW) was equivalent to 5.1 kcal, the mean dialysate protein loss was 13.08 +/- 5.52 g/day and the incidence of peritonitis episodes was 1 every 30.38 months-patient. The daily total caloric intake (by mouth and dialysate) was 30.8 kcal/kg-IBW with a normal subdivision for each diet component: there were not statistically significant differences in distribution according to age, sex and in the follow-up. The mean daily value of protein intake (PI) evaluated by dietary interviews was 0.99 g/kg-IBW, with a significant increase 1 year since the beginning of CAPD; the PI evaluated from urea nitrogen appearance was 1.22 g/kg-IBW. The PI remained stable later in the follow-up and in patients that made use of dietetic supplements, the mean daily increase by this way was 0.47 g/kg-IBW. Anthropometric measurements showed a statistically significant increase of %RBW after 1 year and of TS and % body fat after 3 years.(ABSTRACT TRUNCATED AT 250 WORDS)

Acute pancreatitis as the initial manifestation of systemic lupus erythematosus.
A 20-year-old female with three laboratory ARA criteria pro SLE (LE cells, FANA, and positive Coombs test with hemolytic anemia), not under steroid therapy, developed polyarthritis, erythematous rash and acute pancreatitis simultaneously. The latter regressed with high doses of 6-methylprednisolone. Twenty-five months after remission of pancreatitis, no new clinical manifestations (of SLE) have appeared. In another 74 cases of SLE with an average follow-up of 3 years and 8 months there were no other cases of pancreatitis.
