[Survey on smoking in nursing students]. / L'abitudine al fumo negli studenti del Corso di Laurea in Infermieristica dell'Università di Pavia.

The study reports the results of a survey about smoking collected by a self-administered questionnaire in nursing students at Pavia University. Responders were 393 (80%: M = 132, F = 261, mean age 24.66 +/- 5.64). 45% of the students (51.5% males and 41.8% females) were smokers. Cigarettes consumption was 12.33 cigarettes/day in males and 10.49 cigarettes/day in females; males began smoking at 16 years of age, while females at 17 years. Smoking in family members as well as father's educational level were positively associated to smoking. 66.5% of smokers stated they would like to quit and the most of them are pressed in this decision by family (49.7%) and friends (49.2%). The results of the study describe an unhealthy lifestyle: in future it seems necessary to organize counselling or interventions in order to quit smoking.

Evaluation of outcomes in SPA-treated osteoarthrosic patients.

INTRODUCTION: Osteoarthrosis is the most prevalent joints disorder and it is also the most frequent cause of physical disability in the elderly. When surgery is not indicated, symptomatic drugs are generally used. These treatments are frequently associated to balneotherapy. In fact, balneotherapy or spa therapy has been widely used in classical medicine as a cure for such diseases. The aim and significance of this study is to evaluate the impact of thermalism in subjects suffering from osteoarthrosis. METHODS: We randomly selected 220 osteoarthrosic subjects (STs = spa treatment subjects), aged from 40 to 90, that usually undergone mud pack therapy and balneotherapy at least once a year. They were enrolled in thermal establishments in the Euganean Basin. We also recruited, as control group, 172 osteoarthrosic subjects (NCs = normal care subjects) that never underwent any spa therapy. A questionnaire, comprehensive of a disability score, was administered by physicians to each subject. RESULTS: STs reported to suffer from osteoarthrosis for more years than NCs. Furthermore STs significantly suffered more than NCs from pain in several joints, and they also showed a more elevated average number of painful joints. In spite of that, STs used less drugs than NCs, and showed a higher degree of disability due to osteoarthrosis (p < 0.001). CONCLUSION: The regular use of mudpack and balneotherapy seem to improve the wellness, and the spa treatment seems to help the achievement of this goal. In this regard it might be important to encourage new investigations in order to assess in which measure thermal therapy contribute to the wellness improvement.

Nutritional habits of subjects with Type 2 diabetes mellitus in the Mediterranean Basin: comparison with the non-diabetic population and the dietary recommendations. Multi-Centre Study of the Mediterranean Group for the Study of Diabetes (MGSD).

AIMS/HYPOTHESIS: The aim of this study was to compare the nutritional habits of Type 2 diabetic patients among Mediterranean countries and also with those of their background population and with the nutritional recommendations of the Diabetes and Nutrition Study Group. METHODS: We did a cross-sectional study of 1833 non-diabetic subjects and 1895 patients with Type 2 diabetes, in nine centres in six Mediterranean countries. A dietary questionnaire validated against the 3-Day Diet Diary was used. RESULTS: In diabetic patients the contribution of proteins, carbohydrates and fat to the energy intake varied greatly among centres, ranging from 17.6% to 21.0% for protein, from 37.7% to 53.0% for carbohydrates and from 27.2% to 40.8% for fat, following in every centre the trends of the non-diabetic population. Furthermore, diabetic patients compared to the corresponding background population had: (i). lower energy intake, (ii). lower carbohydrate and higher protein contribution to the energy intake, (iii). higher prevalence of obesity, ranging from 9 to 50%. The adherence to the nutritional recommendations for proteins, carbohydrate and fat was very low ranging from 1.4 to 23.6%, and still decreased when fibre was also considered. CONCLUSION/INTERPRETATION: In diabetic patients of the Mediterranean area: (i). dietary habits vary greatly among countries, according to the same trends of the background population; (ii). the prevalence of obesity is much lower than the 80% reported for patients with diabetes in Western countries; (iii). Carbohydrate intake is decreased with a complementary increase of protein and fat consumption, resulting to a poor compliance with the nutritional recommendations.

Nutritional habits in the Mediterranean Basin. The macronutrient composition of diet and its relation with the traditional Mediterranean diet. Multi-centre study of the Mediterranean Group for the Study of Diabetes (MGSD).

OBJECTIVE: To compare the nutritional habits among six Mediterranean countries and also with the various official recommendations and the 'Mediterranean diet' as originally described. DESIGN: Cross-sectional study. SETTINGS: Three centres in Greece, two in Italy and one in Algeria, Bulgaria, Egypt and Yugoslavia. SUBJECTS: Randomly selected non-diabetic subjects from the general population, of age 35-60, not on diet for at least 3 months before the study. INTERVENTIONS: A dietary questionnaire validated against the 3-Day Diet Diary was used. Demographic data were collected and anthropometrical measurements done. RESULTS: All results were age adjusted. Energy intake varied in men, from 1825 kcal/day in Italy-Rome to 3322 kcal/day in Bulgaria and in women, from 1561 kcal/day in Italy-Rome to 2550 kcal/day in Algeria. Protein contribution (%) to the energy intake varied little, ranging from 13.4% in Greece to 18.5% in Italy-Rome, while fat ranged from 25.3% in Egypt to 40.2% in Bulgaria and carbohydrates from 41.5% in Bulgaria to 58.6% in Egypt. Fibre intake, g/1000 kcal, ranged from 6.8 in Bulgaria to 13.3 in Egypt and the ratio of plant to animal fat from 1.2 in Bulgaria to 2.8 in Greece. The proportion of subjects following the WHO and the Diabetes and Nutrition Study Group (DNSG) of the EASD recommendations for carbohydrates, fat and protein ranged from 4.2% in Bulgaria to 75.7% in Egypt. Comparison with the Mediterranean diet, as defined in the seven Country Study, showed significant differences especially for fruit, 123-377 vs 464 g/day of the Mediterranean diet, meat, 72-193 vs 35 g/day, cheese, 15-79 vs 13 g/day, bread, 126-367 vs 380 g/day. CONCLUSIONS: (a) Dietary habits of the 'normal' population vary greatly among the Mediterranean countries studied. (b) Egypt is closest to the DNSG recommendations. (c) Significant differences from the originally described Mediterranean diet are documented in most Mediterranean countries, showing a Westernization of the dietary habits.

Ultrasound guided percutaneous ethanol injection in the treatment of cystic thyroid nodules.

OBJECTIVE: The management of cystic lesions in the thyroid remains controversial. We examined the efficacy and safety of ultrasound guided percutaneous ethanol injection for the treatment of benign cystic thyroid nodules in euthyroid patients. STUDY DESIGN: (A) Preliminary randomized trial: 20 patients with predominantly cystic thyroid nodules were randomized in two groups and followed up for 1 month. Group 1 underwent fine needle aspiration of the fluid component of the nodules; Group 2 underwent percutaneous ethanol injection at the end of fine needle aspiration of the cyst fluid. (B) Prospective study: 32 patients with the same clinical characteristics (Group 3) were treated by fine needle aspiration and percutaneous ethanol injection, and followed up for 12 months. METHODS: Groups 1 and 2: clinical evaluation, thyroid ultrasonography, thyroid scintiscan and serum thyroid hormone profile were performed before treatment and one month later. Group 3: clinical evaluation, thyroid ultrasonography and serum thyroid hormone profile were performed in basal conditions and 1, 3, 6, 9, 12 months after treatment. Thyroid scintiscan was performed before treatment and 3-6 months later. RESULTS: (A) Randomized study: one month after treatment, nodule volume decrease in Group 2 was significantly higher than in Group 1 (Group 2: median 14.75 range 6-29.9 ml; Group 1: median 3.65 range 0.2-18.5 ml; P < 0.01). Nodule volume reduction was greater than 50% versus baseline in 8 (80%) patients in Group 2 and in 3 (30%) patients in Group 1 (P < 0.01). (B) Prospective study (Group 3): a significant nodule volume reduction (P < 0.01 vs pretreatment) was observed 1 and 12 months after percutaneous ethanol injection (pretreatment: median 14.5, range 1.5-65.8 ml; 1 month: median 3.5, range 0.4-38.9 ml; 12 months: median 2.5, range 0.4-34.5 ml). Nodule volume reduction greater than 50% was recorded in 24 (80%) patients. Groups 1-3: recurrence of cyst fluid was demonstrated by ultrasonography in 8 patients of Group 1, in 3 patients of Group 2 and in 1 patient of Group 3. No relevant adverse effects or significant biochemical changes were observed. CONCLUSIONS: Ultrasound guided percutaneous ethanol injection of cystic thyroid nodules is a safe, low-cost and effective therapeutic procedure in patients with benign thyroid cystic nodules. Indeed, nodule volume reduction was significantly greater and more frequent in patients treated by percutaneous ethanol injection than in those patients who underwent fluid aspiration alone. These results were confirmed in a long-term prospective trial and only one fluid recurrence was observed during 12 months of follow-up.

[Usefulness of ultrasound and CT in the diagnosis of complications caused by surgical sponges left in the abdominal cavity]. / Utilità degli US e della TC nel riconoscimento delle complicanze da garze ritenute nel cavo addominale.

The identification of surgical sponges left in the abdomen and their complications (gossypiboma) creates difficult diagnostic problems in the absence of radio-opaque markers. The phlogistic septic or aseptic reaction to the presence of a foreign body produces nonspecific symptoms and may vary according to the site of the lesion and its relationship with contiguous viscera. Plain abdomen films and the barium meal give some information (mainly topographic), but are usually insufficient for correct diagnosis. As proved by the three case reports discussed, US images (strongly attenuating mass with intense acoustic shadows in a fluid collection) and especially the CT images (mass containing a striped, spotted and whirlike pattern) may be highly indicative, permitting correct preoperative diagnosis.

[Aneurysms of the hepatic artery. Clinico-radiologic study]. / Gli aneurismi dell'arteria epatica. Studio clinico-radiologico.

A series of 7 cases of hepatic artery aneurysm is reported, pointing out the different features for etiology, localization, shape and size. The diagnostic imaging methods are then analyzed. Conventional radiology is actually useless. Sonography is hardly ever conclusive, even if the association of real time-US with echo-Doppler is likely to be promising. CT often concludes the diagnostic procedure, though the small size of aneurysms may limit its efficacy. Arteriography is the only method fit to occasionally find out small aneurysms and clear eventual diagnostic doubts; it's also mandatory before surgical treatment and allows percutaneous embolization. MR is likely to offer interesting perspectives.

[Rounded atelectasis of the lung. A well defined radio-tomographic syndrome]. / La atelettasia rotonda del polmone. Una sindrome radiotomografica ben definita.

Rounded atelectasis (AR) is an unusual type of pulmonary peripheral collapse which may mimic a tumour mass. Seven patients with AR underwent radiological work up by mean of multiple imaging modalities; radiographic and conventional tomographic features were invariably sufficient to make the correct diagnosis. For this reason, more sophisticated or invasive diagnostic procedures are presently not indicated.
