RESUMO

Although many studies have been carried out in order to understand the implication of copper (Cu) in the pathogenesis of multiple sclerosis (MS), the exact role that this metal plays in the disease is not still clear. Because of the lack of information in this subject, the present study compared the serum and cerebrospinal (CSF) levels of copper in MS patients in respect to a control group, matched for age and sex, finding a significant increase of metal concentrations, in both biological fluids of MS subjects. To confirm the possible impairment of Cu metabolism, we analyzed ceruloplasmin (Cp) level and activity, seeing as this protein is an established peripheral marker in diseases associated with Cu imbalance. By comparing these two parameters between control and MS subjects, we found an increase of Cp levels, associated with a decrease in Cp activity, in the second group. By analysing these data, free copper levels were calculated, significantly increased in serum of MS subjects; the increase in free copper could be one of the predisposing factors responsible for the Cu altered levels in CSF of MS patients. At the same time, this alteration could be attributable to the inability to incorporate Cu by Cp, probably due to the high oxidative environment found in serum of MS patients. Overall, all these copper alterations may play a role in MS pathogenesis.

RESUMO

This cross-sectional study investigated with two-dimensional gel electrophoresis coupled to MALDI-TOF and MRI the relationship between PBMCs protein expression profile and whole-brain atrophy in 16 unselected RR-MS IFN-treated patients compared with 6 RR IFN-untreated and 12 matched healthy control subjects. Grey/white matter fraction, T1/T2 lesion load and clinical variables were considered too. Twenty six proteins showed significant differential expression among RR IFN-treated patients and control samples. Four of these (IN35, GANAB, PP1B, SEPT2) resulted correlated with clinical and MRI findings in RR IFN-treated MS patients. Future clinical applications remain to be validated by other techniques and confirmed by a larger study.

RESUMO

We analyzed six cases of progressive supranuclear palsy (PSP) from 1 January 1998 to 31 June 2002. All patients underwent a complete range of laboratory tests, head computed tomographic (CT) scan or magnetic resonance imaging (MRI); three were evaluated by formal neuropsychological examination. All were taking L-dopa or dopamine agonists. At the onset of PSP the initial diagnosis was almost always Parkinson's disease. The head CT scan or MRI findings were non-specific, while neuropsychological testing disclosed cognitive impairment, with predominant subcortical-frontal involvement. We emphasize the still obvious current difficulty in diagnosing PSP at an early stage in clinical practice. Therefore it is essential to formulate better clinical diagnostic criteria, to permit correct management of the disease.

RESUMO

The organizational appropriateness of hospital stays is an expression of a hospital's efficiency and aim of the management control. The AEP (American Version)/PRUO (Italian Version) protocol is specific for measuring the organizational appropriateness of hospital stays. The aim of this study is the comparative analysis of the organizational appropriateness of hospital stays in Careggi Hospital of Florence and in all hospital Departments in 1995 and 1998. In 1998 the AEP/PRUO protocol was applied to 2148 samples of hospital stays out of 38,968 eligible hospitalizations, and in 1995 a sample of 1989 hospital stays out of 35,108. In 1998 2,148 admissions and 15,338 days of hospitalization were tested. In 1995, 1989 admission days and 12,264 days of hospitalization were tested, 63 departments were studied. In 1995 the first edition of the protocol was applied, in 1998 the second. A sample of 218 of the 1998 hospital stays was tested with both editions to evaluate the impact of differences. In 1998, with the second edition of the protocol, the inappropriateness rate of admission days and hospitalization days and the rate of in-patients inappropriate hospital stays was respectively 38.0%, 43.8% and 18.5%. Compared with 1995 results, the rates increased +6.2%, 6% and +7.5% respectively. Instead, with the first edition of the protocol, the rates were 29.7%, 37.6% and 10.7% and, compared with 1995, they were reduced -2.1%, -0.6% and -0.3%. The longitudinal multilevel analysis has allowed the evaluation of the performance of each department.

RESUMO

This retrospective, observational study was performed to evaluate the structure and the content of the nursing documentation in the Azienda ospedaliera Careggi, Firenze in 1998. To this aim we review 1964 nursing records including both notes by turns and care plans. One-thousand-one-hundred-and-twenty-five records came from surgical and 839 from medical wards. From the selected records, every day of the hospital stay, including both the admission and the discharge, were evaluated, so that the studied days were a total of 18,683. Only 32% of the nursing records had a global assessment of patient situation on admission. A medical diagnosis was observed in 84% of the cases, but a nursing diagnosis was absent in over 99.5% of the charts. During stay most notes were related to medical treatment and visits. Nursing notes were lacking in 32% of turns, while "nothing to report" was recorded in another 15.5% of cases. A nursing care plan was present in a minority of records. A final evaluation of planned nursing interventions was reported in approximately 5% of the charts. Nursing care plans were updated during stay in less than one tenth of cases. Discharges notes were absent in slightly more than 80% of the cases. This survey confirms the importance of continuing education and supervision in nursing documentations, if a reliable source of nursing information has to be developed. Future nursing records should include only essential information, avoiding any overlap with medical charts.

RESUMO

In this study we evaluated the smoking habits, beliefs and attitudes of nurse and medical students at the University of Siena and Florence, Italy. Students who entered the 1st year of school in 1998 were asked to complete a self-administered anonymous questionnaire. Two hundred medical students completed the questionnaire; they had a mean age (+/-SD) of 19.8+/-1.7 years and 68% were females. A total of 205 nurse respondents answered to the questionnaire; they had a mean age of 21.8+/-4.1 years and females were 83% of the total. The overall response rate among students always remained higher than 85%. Thirty per cent of medical students were current smokers, and 5% former-smokers. A total of 43% of nurse students were current smokers and 11.5% former-smokers. Nurse students were more likely to smoke than medical students (p = 0.001). Among current smokers, the number of daily cigarettes smoked and the degree of nicotine addiction did not differ between groups. The prevalence of maternal smoking were higher among nurse students. In spite of students' beliefs the knowledge about smoking remained generic in both groups. Nurse students were less aware than medical students of their special responsibility towards people about tobacco smoking. Such a difference remained significant also after adjustment for smoking status (p < 0.01). Students overestimated the prevalence of current smokers among health caregivers of the local hospitals, and Italian people and adolescents. Targeted and continuous training about smoking prevention should be mandatory in Italian medical and nurse schools.

RESUMO

This prospective cohort study has been performed to evaluate the changes in student nurses smoking habits and beliefs during their training. The source of information was an anonymous questionnaire about tobacco smoking, administered to students who entered the first year of School of Nursing in Florence in 1991-1992, 1992-1993 and 1993-1994. Five hundred and thirty-six (95%) of these student nurses completed the questionnaire. Five hundred and one (93%) of these 536 respondents completed the questionnaire again at the end of the third (final) year of training. Student nurses who smoked increased the average number of cigarettes smoked per day (p < 0.01) and the degree of dependence to nicotine (p < 0.01). Tobacco smoking remained widespread and the percentage of ex-smokers who started smoking again increased (p < 0.05). The knowledge about the health hazards due to tobacco smoking remained generic and the prevalence of current smokers among student nurses and health care workers was overestimated. We conclude that Nursing School does not succeed in reducing the smoking habits of students. Effective antitobacco strategies and smoking cessation services still need be organized in Italy.

RESUMO

A group of 273 health care workers, at risk of HBV infection, underwent vaccination with recombinant HBsAg produced in mammalian cells and containing protein sequences coded by both the S and pre-S2 regions (Genhevac B). Preliminary results show that a very early pre-S2 response occurred which may be useful in post-exposure prophylaxis. This observation, in addition to reduced influence by the vaccination protocol, provides grounds for optimism in spite of the fact that the efficiency spectrum of this vaccine was not superior to that of recombinant vaccines produced in yeast.

RESUMO

PIP: Abortion became legal in Italy in May 1978. At the Obstetrical and Gynecological Clinic of the University of Modena, Italy, 2029 interventions were done between June 1978 and August 1979. During the same period of time there was a constant decrease in the number of deliveries and in the number of spontaneous abortions, in reality, illegally induced abortions. The abortion method used within the 1st 90 days of pregnancy was vacuum aspiration under local anesthesia. The largest group of abortion seekers was between 21-26 years of age, and about 46.3% came from the city of Modena itself. 55.9% of women were professionals, and 44.1% nonprofessionals; of these 71.8% were housewives, mostly married to factory workers. About 63% of women were married; 31.8% were nulliparous, 27.7% were primiparous, 40.5% were multiparous; 79.9% had never had an abortion before. 74.6% of certificates for abortion had been given by one of the public family health centers. 73.4% of patients were hospitalized for 1 day only; 22.9% for 2 days. There were 40 cases of complications, or 1.98%, mostly bleeding. There were only 17 cases of interruption of pregnancy after the 90th day, or 0.83% of the total; 10 cases were for eugenic reasons, and 7 because of the psychological health of the mother. Of all the other instances 35.9% of causes for abortion were of a socioeconomic order, 36.2% because of family reasons, 20.9% because of health reasons. Method of contraception used was coitus interruptus in 88.9% of patients, spermicidal agents in 2.7% of cases, and the condom for 1.9%.^ieng
