Alcohol consumption and micronutrient intake as risk factors for liver cirrhosis: a case-control study. The Provincial Group for the study of Chronic Liver Disease.

Purpose: The purpose of this study was to assess the relationship of alcohol consumption and intake of 15 selected micronutrients with risk of liver cirrhosis.

Methods: Data from a case-control study performed in 1989-1990 in central Italy involving 115 incident cases and 167 hospital controls were used.

Results: Cases and controls did not differ for mean daily intake of calories, carbohydrates, lipids, and proteins.

Cardiological aspects of growth hormone and insulin-like growth factor-I.

In recent years it has been demonstrated that both GH deficiency and excess include in their advanced clinical manifestations an impaired cardiovascular function, which may reduce life expectancy. This observation has allowed the investigation of the role played by the GH/IGF-I axis on cardiac structure and function. In particular, several recent experimental and clinical studies support the evidence implicating GH and/or IGF-I in the regulation of heart development.

Mortality in psychiatric hospital patients: a cohort analysis of prognostic factors.

Background: This work followed a group of patients living in a psychiatric hospital in Central Italy in 1978 at the time of enforcement of the Italian reform law (No. 180) for closing down mental hospitals. The study had the following aims: a) to compare in terms of mortality patients discharged into the community with patients who did not experience deinstitutionalization; b) to determine the survival of the cohort of patients and to analyse prognostic risk factors for death; c) to analyse differences in mortality rates between psychiatric patients and the general population.

High stroke incidence in the prospective community-based L'Aquila registry (1994-1998). First year's results.

Background And Purpose: Changes in stroke incidence are likely to occur as a consequence of aging of the population, but evidence for this hypothesis is lacking.

Methods: A prospective community-based registry of first-ever strokes (1994 to 1998) classified according to the International Classification of Diseases, 9th Revision (ICD-9) was established in the L'Aquila district, central Italy, with a total population of 297,838 (1991 census). Patients were identified by active monitoring of multiple sources, including general practitioners.

Female sex and the risk of liver cirrhosis. Collaborative Groups for the Study of Liver Diseases in Italy.

Background: Evidence on gender-related differences in susceptibility to alcohol-induced liver diseases is questionable with regard to both methodologic and clinical aspects. With the aim to assess the role of gender in the risk of liver cirrhosis, independently and in combination with known risk factors, data from three case-control studies performed in various Italian areas were analysed.

Methods: The cases were 462 cirrhotic patients (300 men and 162 women) admitted for the first time to hospital for liver decompensation.

Is alcohol a risk factor for liver cirrhosis in HBsAg and anti-HCV negative subjects? Collaborative Groups for the Study of Liver Diseases in Italy.

Background/aims: In order to evaluate the association between alcohol intake and the risk of liver cirrhosis in the absence of B and C hepatitis viruses, we analyzed data from three hospital-based case-control studies performed in various Italian areas.

Methods: From the case and control series we excluded HBsAg and/or anti-HCV positive patients. Cases were 221 cirrhotic patients admitted for the first time to hospital for liver decompensation.

Failure of long-term therapy with sodium valproate in Cushing's disease.

The aim of the current study was to evaluate the effectiveness of a long-term treatment with sodium valproate in 19 patients with Cushing's disease. Before therapy beginning, the patients were subjected to acute test with 600 mg sodium valproate. Then, they were subjected to a 3-month therapy with sodium valproate at the dose of 600 mg/day before surgery (presurgical study).

Effect of growth hormone on cardiac function.

At present, there is a growing body of evidence implicating growth hormone (GH) and/or insulin-like growth factor-I (IGF-I) in the intricate cascade of events connected with the regulation of heart development and hypertrophy. In addition, advanced clinical manifestations of abnormal GH levels almost always include impaired cardiac function, which may reduce life expectancy. This finding is related both to a primary impairment of heart structure and function and to metabolic changes such as hyperlipidaemia, increased body fat and premature atherosclerosis.

Mother to infant transmission of coinfection by human immunodeficiency virus and hepatitis C virus: prevalence and clinical manifestations.

The prevalence and the clinical course of hepatitis C virus (HCV) infections were studied in 23 HIV-1-infected children, who were born to 22 mothers with HIV-1/HCV coinfection. During the follow-up only two children (8.7%) showed persistent anti-HCV antibodies and circulating HCV RNA.

Detection of IgM antibodies to human herpesvirus 6 in Romanian children with nonprogressive human immunodeficiency virus disease.

The prevalence of human herpesvirus 6 (HHV-6) infection and the course of human immunodeficiency virus (HIV) disease were investigated in 25 Romanian children with nosocomial HIV-1 infection. HHV-6 IgM and IgG antibodies were detected by enzyme immunoassay (EIA) and immunofluorescence assay (IFA) at the beginning of the study and after 18 months, concomitantly with collection of virologic, immunologic and clinical data. The initial HHV-6 seropositivity was 92% by EIA and 76% by IFA, whereas final testing showed 100% positivity by EIA and 84% by IFA.

Interaction between dietary pattern and alcohol intake on the risk of liver cirrhosis. The Provincial Group for the Study of Chronic Liver Disease.

In order to assess the inter-relationship between nutritional intake and alcohol consumption on the risk of liver cirrhosis we performed a hospital-based retrospective case-control study. We enrolled 115 cases admitted to hospital for liver decompensation at their first diagnosis of liver cirrhosis and 167 hospital controls without evidence of liver disease admitted for acute diseases unrelated to alcohol intake. Daily alcohol intake and average nutrient intake were measured throughout the patient's life, using a reproducible questionnaire.

Auditory brainstem responses in thyroid diseases before and after therapy.

The aim of this study was to evaluate through the auditory brainstem responses (ABRs) the electrical events generated along the auditory pathway in 56 adult patients affected with hyper- and hypothyroidism. Twenty-four normal-hearing hyperthyroid patients affected with Graves' disease and 32 normal-hearing hypothyroid patients (9 with subclinical and 23 with overt hypothyroidism) were subjected to standard (clicks at 21 pps) and sensitized ABR with masking wide-band (masking noise). In addition, thyroid scintiscan and ultrasonography, free T3 and T4, total T3 and T4, TSH, antimicrosomal and antithyroglobulin antibodies, audiogram and impedance tests were performed in all the patients.

Growth rate and growth hormone response to growth hormone-releasing hormone challenge in slowly growing children during chronic administration of clonidine.

In this study the effects of chronic administration of clonidine, an alpha-2-adrenergic agonist, on the growth rate and GH response to GHRH in 12 "slowly growing" children were reported. Clonidine was administered at the dose of 0.04 mg/m2 body surface twice daily along 12 months.

The effect of drinking coffee and smoking cigarettes on the risk of cirrhosis associated with alcohol consumption. A case-control study. Provincial Group for the Study of Chronic Liver Disease.

In order to assess the interaction between alcohol intake, tobacco smoking and coffee consumption in determining the risk of liver cirrhosis we carried out a hospital-based case-control study involving 115 patients at their first diagnosis of cirrhosis and 167 control patients consecutively enrolled in the General Hospitals of the Province of L'Aquila (Central Italy). The mean life-time daily alcohol intake (as g ethanol consumed daily) was measured by direct patient interviews, whose reproducibility was > 0.80 and similar for cases and controls, as checked by interviewing the relatives of a sample of 50 cases and 73 controls.

Mortality study on a cohort of Italian licensed pesticide users.

This study describes the mortality experience in a cohort of 23,401 farmers, residing in southern Piedmont, Italy, and licensed to use pesticides. From 1970 to 1986 the cohort included 340,794 person-years and 2683 deaths were observed. A strong attenuation of the death risk was found due to the healthy worker effect (seen as an active role in the application for the license by the members of the cohort) and due to the limited comparability of the cohort with respect to the reference population.

Serological screening of coeliac disease: choosing the optimal procedure according to various prevalence values.

The aim of this study was to select the best approach for screening coeliac disease patients among populations with different grades of disease prevalence. The diagnostic performance was assessed of class A and G antigliadin antibodies and class A antiendomysium antibodies in 93 consecutive outpatients with suspected malabsorption, 44 of whom (47%) had coeliac disease according to duodenal histological tests. Class G antigliadin antibodies provided the worst diagnostic values, whereas a high diagnostic validity was found for the other two tests.

A strong negative association between alcohol consumption and the risk of hepatocellular carcinoma in cirrhotic patients. A case-control study.

We carried out a hospital-based, case-control study to assess the association of both the Hepatitis B Virus (HBV) infection and the lifetime daily alcohol intake with the risk of developing hepatocellular carcinoma (HCC) in patients with liver cirrhosis (LC). Cases were 62 consecutive inpatients of a Gastroenterology Division in whom a first diagnosis of HCC superimposed on LC was made. Two control groups were used: 310 patients without liver disease, matched 1:5 with cases and randomly selected from inpatients of the same hospital, and 97 consecutive asymptomatic inpatients in whom the first diagnosis of LC was made.

[Long-term results of surgical treatment of early cancers of the stomach].

The postoperative course of 172 patients with early gastric cancer operated between 1974 and 1987 was reviewed with a median follow-up of 7 years. The survival probability at the end of 1989 was 0.916 (excluding operative mortality and other causes of death) or 0.

Alcohol-related problems within the family and global functioning of the children: a population-based study.

We carried out a population-based prevalence study to assess the association between the presence of alcohol-related problems within the family and the risk of disorders in the children's global functioning level. We enrolled 394 children attending nursery, primary and secondary schools and their parents living in two municipalities in Central Italy. Alcohol-related problems within the family were reported by registered records obtained from general practitioners and teachers, who were considered as preference raters.

[Reduction modality of a dietary questionnaire].

The data relative to the average daily intake of 7 nutrients and total energy obtained through the answers to a dietary questionnaire, consisting of 152 items and administered to 200 patients (admitted for acute pathologies) has been analysed. The aim has been to elaborate a questionnaire consisting of a more limited number of items but maintaining a great part of the informative contents from the original questionnaire. For this aim, a multiple regression model with a selection procedure for independent variables, of the stepwise type, has been used, where the dependent variable is the daily average intake of the nutrient and the independent variables are the consumption of each food included in the complete questionnaire (QC).

Amount and duration of alcohol intake as risk factors of symptomatic liver cirrhosis: a case-control study.

We carried out a hospital based case-control study involving 320 patients with symptomatic liver cirrhosis (LC) and 320 pair-matched control individuals, in order to estimate the dose-response relationship between both the daily amount and the duration of alcohol intake and the risk of LC. Lifetime alcohol consumption was measured by a standardized and reproducible questionnaire, and expressed as lifetime daily alcohol intake (LDAI) and duration of alcohol consumption (DAC). The odds ratio (OR) for LC was estimated by the conditional logistic regression.

Effect of age, birth cohort and period of death on Italian liver cirrhosis mortality, 1972-1986.

Liver cirrhosis is one of the main causes of death in Mediterranean countries. A trend towards a global reduction in the mortality rate has been recently reported. In order to clarify better this trend and in an attempt to hypothesize the future pattern of mortality, we analysed data from 254,834 Italian subjects aged 30-79 who died from liver cirrhosis during the period 1972-1986.

Early gastric cancer: follow-up after gastrectomy in 159 patients.

The postoperative course of 159 patients with early gastric cancer operated on between 1974 and 1987 was followed for a median of 7.3 years. The cumulative 10-year survival rate(s.

Non-invasive diagnosis of liver cirrhosis: a comparison between four discriminant functions.

We assessed the performance of 4 methods of discriminant analysis using as independent variables the age and 16 serum tests, for correctly identifying patients with liver cirrhosis among hospitalized patients affected by chronic liver disease without signs of liver failure; 290 patients entered this study: on the basis of laparoscopy with or without liver biopsy, 152 patients had a diagnosis of liver cirrhosis and 138 were classified as chronic hepatitic patients. Due to the non-multinormal distribution of the variables used and to the unequality of the variance-covariance matrices, we compared the following 4 methods: linear discriminant function, quadratic discriminant function, non-parametric discriminant function and logistic regression. The Receiver Operating Characteristic (ROC) analysis was used to compare diagnostic ability of the assessed methods: the quadratic discriminant function was the best performing method.
