Moderate alcohol use and health: a consensus document.

AIMS: The aim of this consensus paper is to review the available evidence on the association between moderate alcohol use, health and disease and to provide a working document to the scientific and health professional communities. DATA SYNTHESIS: In healthy adults and in the elderly, spontaneous consumption of alcoholic beverages within 30 g ethanol/d for men and 15 g/d for women is to be considered acceptable and do not deserve intervention by the primary care physician or the health professional in charge. Patients with increased risk for specific diseases, for example, women with familiar history of breast cancer, or subjects with familiar history of early cardiovascular disease, or cardiovascular patients should discuss with their physician their drinking habits. No abstainer should be advised to drink for health reasons. Alcohol use must be discouraged in specific physiological or personal situations or in selected age classes (children and adolescents, pregnant and lactating women and recovering alcoholics). Moreover, the possible interactions between alcohol and acute or chronic drug use must be discussed with the primary care physician. CONCLUSIONS: The choice to consume alcohol should be based on individual considerations, taking into account the influence on health and diet, the risk of alcoholism and abuse, the effect on behaviour and other factors that may vary with age and lifestyle. Moderation in drinking and development of an associated lifestyle culture should be fostered.

[Obesity and Eating Disorders. Indications for the different levels of care. An Italian Expert Consensus Document]. / Documento di Consensus. Obesità e Disturbi dell'Alimentazione Indicazioni per i diversi livelli di trattamento.

This paper is an Italian Expert Consensus Document on multidimensional treatment of obesity and eating disorders. The Document is based on a wide survey of expert opinion. It presents, in particular, considerations regarding how clinicians go about choosing the most appropriate site of treatment for a given patient suffering from obesity and/or eating disorders: outpatient, partial hospitalization, residential rehabilitation centre, inpatient hospitalization. In a majority of instances obesity and eating disorders are long-term diseases and require a multiprofessional team-approach. In determining an initial level of care or a change to a different level of care, it is essential to consider together the overall physical condition, medical complications, disabilities, psychiatric comorbidity, psychology, behaviour, family, social resources, environment, and available services. We first created a review manuscript, a skeleton algorithm and two rating scales, based on the published guidelines and the existing research literature. As the second point we highlighted a number of clinical questions that had to be addressed in the specific context of our National Health Service and available specialized care units. Then we submitted eleven progressive revisions of the Document to the experts up to the final synthesis that was approved by the group. Of course, from point to point, some of the individual experts would differ with the consensus view. The document can be viewed as an expert consultation and the clinical judgement must always be tailored to the particular needs of each clinical situation. We will continue to revise the Document periodically based on new research information and on reassessment of expert opinion to keep it up-to-date. The Document was not financially sponsored.

Nutritional care routines in Italy: results from the PIMAI (Project: Iatrogenic MAlnutrition in Italy) study.

BACKGROUND/OBJECTIVES: Disease-related malnutrition is a common comorbidity at hospital admission. The purpose of the present report was to describe the data on nutritional care routines collected during the Project: Iatrogenic MAlnutrition in Italy (PIMAI) study, as these may be helpful to avoid iatrogenic malnutrition and improve nutritional policies. SUBJECTS/METHODS: Standards of nutritional care were assessed on the basis of (1) adherence to study protocol (completeness of data collected); (2) attitude in assessing the nutritional status; (3) prescription of nutritional therapy (within 3 days) at least in patients presenting with overt malnutrition (body mass index (BMI) <18.5 kg/m(2) or significant weight loss (>or=10% in 3 months and/or >or=5% in the last month)), regardless of its adequacy, and adherence to current guidelines and (4) attitude in monitoring nutritional status during the stay (number of weight measurements performed compared with those expected). RESULTS: In total, 1583 subjects were assessed. A minimum data set for performing the Nutritional Risk Screening 2002 tool was available in 1284 patients (81.1%), but nutritional screening was possible in every patient by alternative analytical criteria related to food intake, anthropometry and biochemistry. However, several missing values were recorded, particularly in biochemical parameters due to lack of prescription by admission wards. According to ward practices, only 38.2% of the patients had the BMI calculated. A nutritional support was prescribed only to 26/191 patients (13.6%) presenting with overt malnutrition. Finally, we recorded that only 21.6% of the patients (207/960 were randomly selected) had their weight monitored on a scheduled basis. This reality was worse in surgical rather than medical departments (17 vs 26%; P<0.001). CONCLUSION: Present results confirm that in Italy, nutritional care routines are still poor and need improvements.

Pirenzepine and exocrine secretions: a selective agent for gastric glands?

Nineteen healthy volunteers were studied to investigate whether or not muscarinic receptors of different exocrine glands could be distinguished from one another by the use of pirenzepine. A simultaneous evaluation of lacrimation, salivation and gastric secretion was carried out, bethanechol (80 micrograms/kg/hr) being used as a stimulant and pirenzepine (10 or 5 mg i.v.) as an inhibitor. Bethanechol increased salivation significantly and the volume of gastric juice, and non-significantly increased lacrimation and total acid output. Pirenzepine abolished the hypersecretion induced by bethanechol, and decreased the basal level of the exocrine secretions, to approximately the same extent. These experiments seem to demonstrate that if there is a difference among the muscarinic receptors of lacrimal, salivary and gastric oxyntic glands, pirenzepine is unable to discriminate them from one another, at least under the experimental conditions of this investigation.

Lactoferrin concentration in the parotid saliva of patients with chronic pancreatitis.

Lactoferrin is present in pancreatic juice, and greatly increased concentrations are found in the pancreatic juice of patients with chronic pancreatitis. It is not known whether these high levels of lactoferrin represent a genetically determined defect predisposing to the later development of chronic pancreatitis or are simply a consequence of the disease. In view of the morphological and functional similarities between the pancreatic and parotid glands, we have measured the immunoreactive lactoferrin concentration in pure parotid saliva of 30 patients with chronic calcific pancreatitis, 26 controls, 5 patients with proven pancreatic cancer, 2 patients with Sjögren's disease and 2 patients with chronic recurrent parotitis. No difference in the lactoferrin concentration was detected between control subjects and patients with chronic pancreatitis or pancreatic cancer. Raised levels were found in the 4 patients with parotid gland disease. These findings suggest that increased lactoferrin secretion is confined to the exocrine pancreas in patients with chronic pancreatitis and is thus probably a phenomenon secondary to the disease.

[Modification of an experimental model of chronic pancreatic and biliary fistula in the minipig (author's transl)]. / Modifiche di un modello sperimentale di fistola pancreatica e biliare cronica nel minipig.

An improvement in Corring's experimental model in the minipig is described. The model requires: -- a complete diversion of the biliopancreatic secretion and the possibility of its reintroduction into the duodenum; -- a particular anaesthesiological, technical and management problems taken up during the course of the research. Data are also given about basal pancreatic and biliary secretions in this particular experimental model.
