A comparison of five questionnaires to assess alcohol consumption in a Mediterranean population.

OBJECTIVE: To evaluate the reliability of alcohol consumption measured by five different dietary methods in the Catalan Nutrition Survey (1992-1993). DESIGN: The different questionnaires used were: (1) two 7-day food records, (2) five items addressing alcoholic beverages in a 76-item food-frequency questionnaire, (3) a 1-week recall of 13 alcoholic beverages, (4) a 13-item alcoholic beverages frequency questionnaire and (5) two 24-hour recalls. SUBJECTS: Ninety-three of the 120 adults (aged 20 to 70 years) initially recruited completed the questionnaires and provided a peripheral blood sample. RESULTS: Mean daily alcohol intakes as assessed by the questionnaires were very similar. Beer was the alcoholic beverage most frequently consumed, followed by wine and liquor. Eighty-two per cent of the study population consumed less than 20 g of alcohol per day. No biochemical parameters were significantly correlated with alcohol intake estimated from the questionnaires. CONCLUSIONS: We found a satisfactory level of reproducibility and validity in the pattern of alcohol consumption across different levels and types of alcoholic beverage intake. We also found that the self-administered 13-item questionnaire and the 1-week recall were the best techniques to measure moderate or low alcohol consumption, suggesting that the two methods are the most suitable to assess overall alcohol intake in the general population.

[The ISCA (Systematic Interview of Alcohol Consumption), a new instrument to detect risky drinking].

BACKGROUND: The World Health Organisation Collaborative Project on Alcohol and Primary Health Care has stressed the need to develop standardised screening tools to enable early identification. The aim of this study was to develop a new systematic tool to register alcohol consumption and to validate its usefulness in order to detect risky drinking in primary health care settings. SUBJECTS AND METHOD: The Systematic Interview of Alcohol Consumption (ISCA) was administered together with the Alcohol Use Disorders Identification Test (AUDIT), which was used as main external criterium, to 255 patients who attended 5 primary health care centers. RESULTS: The correlation between both procedures was highly positive and significant (r = 0.831; p < 0.001). The cut-off scores (> 28 for men and > 17 for women) showed an ISCA sensitivity rank to detect risky drinking of 70-81% for men and 46-100% for women. The ISCA specificity ranks were 82-99% and 97-100%, respectively. CONCLUSIONS: The ISCA seems to be useful to detect risky drinking and it is easy to administer by primary health care professionals. ISCA and AUDIT can be used indistinctly and complementarily.

[Primary intestinal T lymphoma with massive eosinophilia].

Primary intestinal T lymphoma with eosinophilia is an infrequent tumour. Its rarity account for the paucity of similar cases recorded in the literature. It affects predominantly middle-aged men and may be associated with ulceration, fistula formation and intestinal perforation with an abdominal mass. Lesions of the intestine with massive tissue eosinophilia may be a difficult diagnostic problem, but this entity displays distinctive histological features. The presence of intense tissue eosinophilia is a T-cell dependent lymphomas response. We describe a case of T lymphoma involving small intestine with massive eosinophilia.

[Eosinophilic gastroenteritis].

Eosinophilic gastroenteritis is a rare clinicopathogenic entity of an unknown aetiology in which a variety of digestive symptoms are associated to the eosinophilic infiltration in the intestinal wall. The clinical features depend on the site of eosinophilic infiltration, and the association with peripheral eosinophilia is very frequent. The radiologic findings were not specific and the diagnostic is based on the endoscopic and/or peroral gastrointestinal biopsy. The response to steroid therapy is spectacular. The etiology is unknown but we review the recent literature.

Why has alcohol consumption declined in countries of southern Europe?

Alcohol consumption seems to be decreasing in the traditional wine countries of southern Europe. This paper describes the evolution of alcohol consumption over the last 30 years in France, Greece, Italy, Portugal and Spain. For this purpose, data on alcohol production and per capita alcohol consumption in southern Europe are examined, and their reliability discussed. To analyse alcohol-related mortality, liver cirrhosis death rates are also reviewed. Since 1980 overall alcohol production has increased by 10%, while wine production has decreased by 13%. The consumption of pure alcohol equivalent per capita has continually decreased, from a peak of 14 litres per year in 1974 to 10.4 litres in 1992. The reduction is dramatic for wine (42.3%) and slight for spirits (4.7%), while beer consumption has grown by 36.6%. These data seem to confirm a European trend towards the homogenization of drinking patterns. Marketing factors, public health policies, the evolution of prices and taxation, European Union agricultural policies, a growing awareness of public opinion about the toxicity of alcohol and competition from non-alcoholic drinks are all factors that may partially explain these observed changes.

Protamines and related proteins from spermatozoa of molluscs. Characterization and molecular weight determination by gel electrophoresis.

The spermatozoa of most species of molluscs contain a mixture of proteins with compositions related to those of histones and protamines. The various components present in the spermatozoa of Cryptochiton stellerii, Donax trunculus, Mactra corallina and Gibbula divaricata have been isolated and characterized. The results obtained, taken together with those previously found (Subirana, J.A., Cozcolluela, C., Palau, J. and Unzeta, M. (1973) biochim. Biophys. Acta 317, 364--379), show that in all the molluscs studied one or more arginine-rich components are present. The molecular weight of these proteins varies vary much in different species and is usually much greater than in conventional fish protamines. Conventional histones, as well as lysine-rich proteins of low molecular weight, have also been found in ripe spermatozoa of several species. The molecular weights have been estimated by gel electrophoresis, using polymerized iridine as a standard.

[Reporting new HIV cases in Catalonia, Spain: is technical consensus feasible?].

OBJECTIVE: To describe the process performed in Catalonia (Spain) to design an information system for monitoring new cases of HIV infection. METHODS: A survey was used to evaluate perception of the need for notification of HIV infection by health care professionals (n = 106), as well as their opinions of the various possibilities for the implementation of the notification system. As a result of this evaluation, a specific technical report defining the objectives and technical characteristics of the new notification system was produced. The feasibility of the system in health centres was evaluated through discussions with health care professionals, health authorities and Non-Governmental Organizations, and a second survey was designed to evaluate the use of a personal identification code (PIC) from the individual health card (IHC). This process took plabe between 1998 and 2000. RESULTS: A total of 84.5% of the health care professionals believed that HIV notification should be mandatory and confidential; 90.4%, were of the opinion that notification would enable identification of the epidemiological characteristics of infected individualos, and 75% believed that these individuals would have to be identified by name. Finally, 66% of the health care professionals believed that the use of the PIC from the IHC would be feasible as the personal identifier in HIV notification. A final proposal was draw up and 1 January, 2001 was set as the date to initiate the pilot phase of the new HIV notification system. CONCLUSIONS: Most of the health care professionals surveyed expressed the need for notification of HIV infection, and for such notification to receive institutional endorsement. They also believed that, as with other diseases of individualized mandatory reporting, notification should be carried out with a single personal identifier. The information obtained from notification of HIV infection is essential for the optimal planning of preventive programs and the provision of health services. The main difficulties observed were that HIV infection has not been included among the diseases of mandatory reporting, as well as the low implantation of the PIC in the hospitals' clinical registries. All the sectors involved have an important role to play in creating the conditions necessary for the notification system of new cases of HIV infection to be feasible and useful.

Five-year outcome in alcohol dependence. A naturalistic study of 850 patients in Catalonia.

A prospective, multicentre study was designed to evaluate the impact of a treatment programme in alcohol-dependent patients (n = 850). Drinking status and measures related to quality of life such as morbidity, mortality, alcohol-related problems, and psychological and social functioning were assessed 5 years from the initial contact with the patient. Five years after the initial visit, drinking status followed a bimodal distribution: 371 patients (43.6%) were found to be abstinent, 323 (38%) were heavy drinkers, and only 55 (6.5%) were controlled drinkers. A total of 65 (7.6%) patients died during the study, 33 (3.9%) patients were lost to follow-up and three (0.3%) patients were not collaborative. Differences in health-related issues were identified for each of the drinking status categories. Abstinent patients presented with significantly better outcomes than controlled and heavy drinkers on most medical, socio-economic and psychological measures. Heavy drinkers showed significantly worse outcomes than controlled drinkers.
