An outbreak of food poisoning due to a genogroup I norovirus.

Norovirus infection is associated with approximately 90% of epidemic non-bacterial acute gastroenteritis. The objective of this study is to describe an outbreak of norovirus genogroup I gastroenteritis which affected workers in a hospital and was attributed to food prepared by an infected food handler. Forty cases were detected, of whom 80% were interviewed. The index case was the cook employed in the hospital cafeteria. The following symptoms were observed: abdominal pain in 90.6%, vomiting in 71.9%, diarrhoea in 71.9%, general indisposition in 62.5%, headaches in 53.1% and fever in 32.4% of cases. The initial symptoms were abdominal pain in 37% and vomiting in 28%. Of the 14 samples analysed by RT-PCR, 12 (86%) were positive for a genogroup I norovirus. After sequencing the strain was identified as genotype Desert Shield. Many of the foodstuffs consumed were made by hand, favouring transmission from the index case to the cafeteria users.

[Iatrogenic hyperthyroidism secondary to weight loss medication. Predictive factors for their precocious detention].

OBJECTIVE: To establish the differential clinical characteristics between the Iatrogenic hyperthyroidism for not conventional medication for obesity treatment (weight losers) and the endogenous by Graves Basedow disease. PATIENT AND METHODS: Observational and analytical study, populational based, in the one which prospectively were compared cases with Iatrogenic hyperthyroidism (secondary to weight losers) with those with endogenous hyperthyroidism (Graves Basedow disease) as controls. Consisted of the variable clinical record of 100 correlative patients that consulted in specialized attention of endocrinology for Iatrogenic hyperthyroidism secondary to weight losers and for Graves Basedow disease. RESULTS: The differences observed between Iatrogenic hyperthyroidism (secondary to weight losers) (n = 43) as compared to endogenous hyperthyroidism (Graves Basedow disease) (n = 57) were: smaller age (31.8 +/- 10 as compared to 37.8 +/- 12.6 years), greater body mass index (27.6 +/- 7.2 as compared to 23.4 +/- 3.1), smaller goiter frequency (16.3% as compared to 84.2%) as well as absence of signs of ophthalmopathy (0% as compared to 57.9%). Both groups had low levels of TSH, and the difference rests in the values of free T4, low in the first group and increased in the endogenous hyperthyroidism. The odds ratio were: IMC > 27: 3.92 (0.91-16.72), age < 33 years: 5.58 (1.42-21.99), absence of goiter: 23.29 (6.39-84.85). The precedent of weight losers use was not selective of the first group, being detected in a 12.3% of cases of endogenous hyperthyroidism, though in periods of time remoter in relationship to the beginning of the clinic. CONCLUSIONS: In the differential diagnosis of a case of hyperthyroidism, it can be suspected Iatrogenic hyperthyroidism (secondary to weight losers) for medication for the obesity in patients of the feminine sex with overweight, without previous or familiar history of thyroid disease, and in those which in the physical exploration is not verified goiter neither ophthalmopathy.

[Iatrogenic hyperthyroidism. Report of an outbreak].

The clinical observation of a series of 30 patients (age 29.6 +/- 9.8 years, 29 females and 1 male) who were remitted for evaluation of a thyroid dysfunction with a decrease in TSH and free thyroxin with clinical symptoms of hyperthyroidism and absence of goiter or exophthalmous is presented. Most of the patients (90%) had no family or personal history of previous thyroid disease. Anamnesis demonstrated the previous ingestion of uncommercialized prepared weight losers, dispensed in different areas off the pharmacy offices. Seventy-three percent of the patients had received the treatment from the same source (prescriber). In most of the cases (28 out of 30) normalization was observed in thyroid function tests. The demonstrated inefficacy of this medication as well as the health care importance of the problem are discussed.

[Dietary habits of 2 populations of the province of Barcelona (III): energy consumption and macronutrients].

BACKGROUND: The identification of an association between alimentary and nutritional factors and different diseases has led to the study of alimentary habits in different populations. The consumption of energy and macronutrients was analyzed in two urban populations in the province of Barcelona (Spain). METHODS: One thousand thirty-four randomly selected individuals from primary care centers (PCC) were studied by a systematic sampling of all the out patient consultations over one year and to those to whom a semiquantitative questionnaire of frequency foodstuffs was given to estimate their normal diet. The subjects included all those residents in the two towns studied from 13 to 80 years of age who attended the PCC during the study period. RESULTS: The percentage of subjects from Vilanova i la Geltrú who were found to be high consumers of milk and derivatives, fish and vegetables was significantly higher in comparison with subjects from Gavá. The males of both towns presented a higher mean consumption of carbohydrates and energy than the females. On comparison of the consumption between the 2 populations, the mean carbohydrate diet ingested was significantly greater in the population from Gavá in both sexes as was the consumption of energy and total lipids between women and men, respectively. CONCLUSIONS: The population studied presented a clear pattern of Mediterranean diet consumption with elevated ingestion of carbohydrates and monounsaturated fats.

[Dietary habits of 2 populations of the province of Barcelona (I): design and validation of a semiquantitative questionnaire of frequency of food consumption].

BACKGROUND: The identification of associations between alimentary factors and specific chronic diseases has led to the development of valid diet measurement methods. In the present article the design and validation of a questionnaire on the frequency of food consumption is reported. METHODS: From an initial sample of 1,034 inhabitants of two populations in the province of Barcelona, Spain, a sample stratified by age, sex and population of 64 individuals between 13-70 years of age was randomly selected. A semiquantitative questionnaire was initially given to 58 of the 64 subjects including 39 foods or groups of food and these were instructed as to how to follow a registry of food for 7 days in two different periods. The intakes of energy products, macronutrients, fiber, cholesterol and vitamins C, A and E were estimated by the two methods were compared. RESULTS: The means of nutrients estimated were lower in the questionnaire than those obtained by the reports of foods with the exception of the intake of carbohydrates. The range of the correlation coefficients for the values obtained by both methods was of 0.17 for vitamin E and 0.54 for the monounsaturated fatty acids which, after correction for the alternation factor, were found to be 0.20 and 0.67, respectively. Thirty-nine percent of the individuals were classified within the quintile of low consumption with 33% being within the quintile of greatest consumption. CONCLUSIONS: The use of a semiquantitative questionnaire may be useful to describe the dietary habits in a given population and fundamentally when the population studied is to be classified according to the normal consumption of energy and macronutrients.

[Dietary habits of 2 populations of the province of Barcelona (II): comparative study of the frequency of consumption in both populations and its relationship to recommended diet in diabetes].

BACKGROUND: The aim of the present study was to compare the eating habits of two urban populations (Vilanova i la Geltrú and Gavá) of the province of Barcelona, Spain, and determine the relation with the diet recommended in diabetes since this diet does not differ from what is considered "equilibrated diet". METHODS: One thousand thirty-four individuals randomly selected from Primary Health Care Centers (PHCC) by a systematic sampling of all the outpatient consultations over one year to whom a questionnaire on semiquantitative frequencies were studied with the aim of determining their everyday diet. All those between 13 and 80 years of age, residing in the two municipalities studied and who attended the PHCC over the period of the study were included in the study. RESULTS: On comparison of both populations a statistically higher consumption (p < 0.01) of milk products, fish, vegetables, fruits and oils was observed in Vilanova i la Geltrú than in Gavá. Both groups presented a lower intake than recommended of fish, vegetables, and fruits. In contrast a high intake of sugar, ice cream and sugared beverages and foods were observed in the two populations studied and in the younger are groups. CONCLUSIONS: The population of Vilanova i la Geltrú have dietary habits which are closer to those recommended in the diet of diabetics than the population of Gavá.

[Care for the diabetic patient in Catalonia. A study of a population sample].

BACKGROUND: The aim of this study was to determine the clinical and therapeutic profile of both types of diabetics (IDDM and NIDDM) attended at different levels of health care in Cataluña in order to establish quality control and rationalize diabetologic sanitary planning. METHODS: Fifteen centers in Cataluña participated in a study with a total of 1,430 patients. The centers represented different specialized care levels: 6 endocrinology public health out-patient clinics (EO), 4 county hospitals (CH), 3 university hospitals (UH) and 2 private diabetic units (DU). RESULTS: IDDM: a) the percentage was higher in UH and DU (39 and 37) than in CH (26 p less than 0.01) and EO (11 p less than 0.001); b) the youngest were attended in UH (24 +/- 14 years) and the oldest in the EO (39 +/- 17 years, p less than 0.001), occupying the CH and DU at an intermediate position (34 +/- 16 and 32 +/- 17 years) and different than the other two (p less than 0.05); c) 74% of those attended in UH had an evolution of less than 10 years vs 45-58% of the other levels (p less than 0.005); d) no differences were observed in the overall prevalence of complications; e) 37% of the males between 15 and 64 years of age were smokers; f) intensive insulin therapy is more frequently used (p less than 0.05) in DU and UH (56% and 42%) than in EO and CH (19% and 13%); g) the determination of capillary glycemia is generalized (96%); h) 14% had HbA1 or fructosamine lower than the maximum normal value. NIDDM: a) the age of the patients was somewhat lower in DU (59 +/- 11) and UH (58 +/- 11) than in CH (62 +/- 100 and EO (64 +/- 10 (p less than 0.05); b) globally, the rate of insulinization was 55% and home control of glycemia was 43%; c) 47% are hypertense (half of whom are inadequately controlled) and 55% are dyslipemic; d) between 15 and 64 years of age 39% of the males are smokers; e) 27% had HbA1 or fructosamine lower than the maximum normal value. CONCLUSIONS: a) The quality of medical care to diabetics in the centers analyzed is high; b) there is no "patient-type" for level of health care; c) there seems to be more therapeutic "aggressivity" among the health care workers responsible for diabetics in relation to the glucose vs other risk factors.

Prevalence of islet cell antibodies, insulin antibodies and hyperglycaemia in 2291 schoolchildren.

Islet cell antibodies, insulin antibodies and hyperglycaemia were investigated in 2291 healthy schoolchildren. Eight of the subjects had islet cell antibodies and eight had insulin antibodies. However, no schoolchild who was positive for islet cell antibodies also had insulin antibodies present. Hyperglycaemia was observed in five children but neither islet cell antibodies nor insulin antibodies could be detected in the sera from these particular subjects.

Nocturnal insulin and C-peptide rhythms in normal subjects.

Immunoreactive insulin and C-peptide reactive plasma levels in venous blood were studied between 0100 and 0820 h in 10 healthy volunteers to assess nocturnal endogenous insulin secretion and its peripheral extraction. Insulin secretion appeared significantly reduced after 0600 h. No correlations were observed between counterregulatory hormones and insulin secretion during this period. Plasma glucose remained stable throughout the study. An increased peripheral sensitivity to insulin after 0600 h is suggested to explain reduced secretion of insulin.
