The teaching of pharmacology in Italian medical schools: the point of view of Italian doctors

OBJECTIVE: A survey was carried out to gather the opinions of doctors about the current method of teaching pharmacology in Italy. METHODS: A questionnaire was mailed to 3860 doctors, who were asked a series of questions regarding the teaching of pharmacology to medical students in Italian universities. RESULTS AND CONCLUSIONS: The great majority of those who replied considered the teaching they received to be mainly theoretical. The doctors thought that much more time and attention should be dedicated to those pharmacology subjects that are more closely connected to physiopathology and clinical practice (clinical pharmacology).     

The teaching of clinical oncology in Italian medical schools. A survey among teachers and students

BACKGROUND: Oncologists, health care workers and health organizations consider well-performed teaching programs in clinical oncology a fundamental step in cancer control. The aim of our study was to assess the views of teachers and students on the present status of oncology teaching in Italian medical schools and on the most common shortcomings in cancer education. MATERIALS AND METHODS: A survey was carried out among teachers and students of 17 Italian medical schools using two different questionnaires. Six hundred forty-seven students of Northern, Central and Southern Italy in the final two years (5th and 6th) of their medical curriculum and 87 professors of pathology, surgery, internal medicine and medical oncology completed the questionnaires. RESULTS: Doctor/patient relationships and integration among disciplines were the most unsatisfactory aspects of oncology teaching, according to students. Biology, epidemiology, radiotherapy, and medical treatment were felt to be insufficiently treated, whilst diagnostic aspects, clinical management and surgery were rated sufficient. The median number of cancer patients to whom each student had access during his/her training was limited, averaging only 13 patients; however, a high degree of variability was noted. A larger number of patients was generally observed in smaller, less crowded medical schools, with notable exceptions. Although the majority of teachers had clinical practices related to their disciplines, only a small number of students underwent a period of clinical training. Traditional methods of teaching were preferred to innovative methods, while interaction among disciplines was uncommon. CONCLUSIONS: This survey emphasizes the dualism between students' expectations and teachers' ideas about cancer teaching. Doctor/patient relationships and poor attention to practical clinical problems seem the most critical issues for clinical oncology training in Italian medical schools.     

Preliminary results of a nutritional survey in a sample of 35,000 Italian schoolchildren

An investigation of the nutrient intake of a large-scale sample (n = 35,072), drawn from the Italian school-age population (7-10 years) was carried out in a nationwide survey of nutritional patterns. Friuli, the Piedmont, Latium and Sicily regions were selected as representative of the nation's north-south and east-west socio-economic divisions. A food frequency questionnaire was used to assess nutritional intake. Traditional methods of 24-h dietary recall and a weighted food diary were used in subsamples to assess the validity of the food frequency questionnaire. Our data suggest that the average diet of Italian schoolchildren is rich in protein (especially animal proteins) and lipids (prevalently saturated fatty acids), but that carbohydrate and fibre intakes remain generally low. The relatively low calcium intake among girls and a widespread, more than adequate iron intake are also noteworthy. The food and nutrient intakes assessed suggest a dietary pattern with several positive points, but also reveal potential hazards for a wider population spectrum. The type of large-scale nutritional monitoring with a multi-method approach can be used in Italy and elsewhere to describe the dietary trends of a school-age population.     

Hypertension in Haitians: results of a pilot survey of a public teaching hospital multispecialty clinic

Little is known about hypertension in Haitians. We performed a pilot survey of ambulatory Haitian patients in a multispecialty clinic at a large public teaching hospital. Approximately 10% of the clinic population was of Haitian origin. Clinical data were collected on 88 consecutive Haitian patients. Of these 88, 77 (87.5%) were hypertensive (SBP > or = 140 or DBP > or = 90 mm Hg or taking antihypertensive medication). The characteristics of the hypertensive patients were: age 54.1 +/- 13.0 (s.d.) years; 27 men, 50 women; 12/64 (19%) smoked; 7/63 (11%) used alcohol. Diabetes was present in 21/77 (27%). In patients for whom height and weight were available, obesity was present in 52%. Using JNC V criteria, 18 (23%) had Stage 1, 16 (21%) Stage 2, 18 (23%) Stage 3, and 25 (33%) Stage 4 hypertension. Despite 63/77 (82%) being treated for hypertension, only 20 (26%) were controlled (< 140/< 90 mm Hg). Of those under treatment, 29 were taking one drug; 18 (two drugs); 12 (three drugs); and four (four drugs). Target organ damage was evident in 37 (48%), including coronary artery disease (8), CHF (6), chronic renal failure (15), stroke (9), and LVH by ECG (19). There was evidence of severe noncompliance in 32 (42%). We conclude that in this clinic sample, hypertension was highly prevalent and unusually severe in terms of blood pressure (BP) level, refractoriness to treatment, and target organ consequences. Further studies are indicated.     

Continuing medical education in Europe: a survey

The Continuing Medical Education (CME) in Europe Project is conducted by the World Federation for Medical Education, in conjunction with the Association for Medical Education in Europe, the Association for Medical Deans in Europe, and the European Office of the World Health Organization, with Upjohn Medical Sciences Liaison Division. The aim of the Project is to promote the development of CME in all European countries. It also has global relevance: all six Regions participated in initiating the Project, and its progress and outcomes will be generalized to the other five Regions. This Project coordinates information about the important developments in CME in all countries of Europe. In addition to this coordinating function, the Project has a dissemination function, promoting knowledge about good examples and CME experience (demonstration projects) in the countries of Europe. A survey was made of the methods of CME in each country, the informants being the members of the Project's CME Task Force. It consists of nominated representatives from the National Associations for Medical Education of countries in the European Region.     

Deformable models in medical image analysis: a survey

This article surveys deformable models, a promising and vigorously researched computer-assisted medical image analysis technique. Among model-based techniques, deformable models offer a unique and powerful approach to image analysis that combines geometry, physics and approximation theory. They have proven to be effective in segmenting, matching and tracking anatomic structures by exploiting (bottom-up) constraints derived from the image data together with (top-down) a priori knowledge about the location, size and shape of these structures. Deformable models are capable of accommodating the significant variability of biological structures over time and across different individuals. Furthermore, they support highly intuitive interaction mechanisms that, when necessary, allow medical scientists and practitioners to bring their expertise to bear on the model-based image interpretation task. This article reviews the rapidly expanding body of work on the development and application of deformable models to problems of fundamental importance in medical image analysis, including segmentation, shape representation, matching and motion tracking.     

Antibiotic resistance in Pseudomonas aeruginosa: an Italian survey

In order to assess the current level of resistance to widely used antipseudomonal antibiotics in clinical isolates of Pseudomonas aeruginosa, a national survey was undertaken. Fifteen hospitals throughout Italy participated in the study. The University of Catania tested the antibiotic susceptibility of 1005 consecutive clinically significant P. aeruginosa collected from March to June 1995. Lack of susceptibility, according to NCCLS breakpoints, was at the following rates: meropenem, 9.1%; imipenem, 19.3%; ceftazidime, 13.4%; carbenicillin, 27.3%; piperacillin, 12%; ticarcillin/clavulanic acid, 22.8%; amikacin, 10.6%; and ciprofloxacin, 31.9%. About half of the isolates (44.4%) were not susceptible to at least one of the antibiotics tested.     

Bacterial endocarditis: results of a survey in a children''s hospital in France

Recent studies have shown the insulin-like effect of vanadyl sulphate or sodium ortho (or meta-)vanadate administered orally to rats. Toxicity of these drugs and reluctance by the animals to drink the solutions and take food, concerning the amelioration of some diabetes syndrome discussed in 1994 by Domingo et al. (1), McNeill et al. (2) and Wiliams and Malabu (3), prompted us to investigate a new vanadate complex: disodium bis(oxalato)oxovanadate (IV), Na2[VO(OX)2]H2O. The main object of the experiment was to study whether this complex administered as 3 mmol/l solution in 0.5% NaCl during 7 days could act on the subcellular level and influence the activity of liver Golgi membrane galactosyltransferase activity. Free blood sugar level was lowered (but was still higher than in the control group) in diabetic rats after seven days of vanadate action and was accompanied by lowered, however not statistically significant, serum triglyceride levels. The yields of isolated Golgi-rich membrane fractions were about half of the level in diabetic groups (untreated and treated with vanadium) compared with the control groups. Purity of these membrane fractions, expressed as nmol Gal transferred per mg of proteins and per h, was the same in four groups investigated and showed the possibility to compare them. Activity of galactosyltransferase calculated in nmol Gal transferred per 1 g of liver and per 1 h or per whole liver in the same time (as a possibility of glycosylation of the secretory and membrane glycoproteins) was lower in both diabetic groups. However, after vanadium treatment (D+V group), the activity was higher than in untreated diabetic rats (D group) in three of five investigated animals. Vanadyl-oxalate complex did not normalize in a statistically significant manner the enzyme activity which was significantly lower in diabetes than in control. This is similar to insulin influence on the galactosyltransferase activity reported previously by Kaczmarski et al. in 1981 (4) and Kordowiak et al. in 1981 (5).     

Knowledge, attitude and reservations of medical students about organ transplantation: results of a survey during the first year of study

AIM: Establish a list of first year medical students' attitudes, doubts, and knowledge in the fields of organ transplantation and donation. METHOD: Anonymized questionnaire handed out to students during class lectures. RESULTS: 183 questionnaires were distributed and 117 returned (participation: 64%). The average age of the students was 21.6 +/- 2.7 years (range 18 to 38 years); the sample included 71 women (60.7%) and 48 men (39.3%). Only 2 students (2%) were not interested in the subject of organ donation. The students knew very little of the legal aspects of organ donation and 1/4 of them thought there was even a Federal law regarding organ transplantation. When asked if they knew whether a law existed in the Canton of Berne, 44% replied yes, but only 24 (20%) knew that this is contradictory. There was no gender difference in the answers to these question. From 57 students (48%) 246 individual comments on doubts and concerns were analyzed. In this respect, the students mainly questioned whether the donor was truly dead when donation took place (n = 48), if illegal transplantation could be eliminated (n = 44) and if transplantation was truly necessary (n = 43). Some also mentioned religious/ethical doubts (n = 42). In regard to organ donation by a living individual, 27 students were concerned about the health of this donor. 20 students had doubts regarding the pressure possibly applied by family members and friends and as many voiced doubts in regard to premature diagnosis of brain death of potential donors. Only 2 students were concerned about the post-mortem presentation. 45 students (48%) indicated discomfort with the donation of certain organs. They ranked the kidney as the first organ to donate, followed by the pancreas, heart, cornea, intestine, lung and liver. CONCLUSION: The interest in organ donation and transplantation is already strong in fist year medical students in the pre-clinical stage. However, differences from lay public are not readably detectable at this stage of medical training. Adequate information could influence future physicians in their mediatory role.     

Nurses who work in general medical practices: a Victorian survey

A questionnaire survey of 452 general medical practices in Victoria attracted responses from 277 practices, many of which did not employ nurses. The 93 respondents from 85 practices who were nurses reported that they enjoyed flexible working hours and stable employment. While their main reason for working in GPs' rooms was convenience, the most important aspect of their work was interaction with patients and fellow workers. Sixtyseven percent of nurses thought continuing education in specific skills was necessary for their work, 43% thought a post-registration qualification in community health nursing would be desirable and 47% thought a special interest group of nurses working in medical practices would be useful.     

Scope of hypnosis education in academia: results of a national survey

Nutritional husbandry of captive wild ruminants often requires feeding these animals a supplemental diet to enhance their health, reproductive performance, and productivity. Although supplemental diets for wild ruminants are commercially available, few have been evaluated in controlled intake and digestion trials. Voluntary intake, digestive efficiency, nitrogen retention, and gross energy utilization of pronghorn (Antilocapra americana), mule deer (Odocoileus hemionus), mountain sheep (Ovis canadensis), mountain goats (Oreamnos americanus), and wapiti (Cervus elaphus) consuming a high-energy, high-protein pelleted supplement were compared. Voluntary intake of dry matter, energy, and nitrogen were similar (P > 0.34) between mountain goats and mountain sheep and consistently lower (P < 0.03) for these species than for pronghorn, mule deer, and wapiti. Differences in digestive efficiency among species were inversely related to dry matter intake rates. Apparent digestibility of dry matter, organic matter, and neutral-detergent fiber was 10-20% higher for mountain goats and mountain sheep than for the other species (P < 0.04). Although these findings suggest a superior digestive efficiency for mountain goats and mountain sheep, species comparisons are inconclusive because of the confounding effects of season and ambient temperature on voluntary intake and digestion. Under the conditions of this experiment, the diet tested was safe, nutritious, and highly palatable. Protein and energy concentrations appear to be sufficient to meet or exceed known nutritional requirements of captive wild ruminants.     

Contraceptive behavior in the population of the Czech Republic: results of a national survey

Using an anonymous questionnaire the authors investigated in a representative group of the Czech population above 15 years of age (862 men and 857 women) the use of the main contraceptive methods. During the first intercourse more than half the respondents did not use any contraception, a condom was used only by 19% men and 14% women. In a steady partnership the most frequent method of contraception is coitus interruptus, whereby experience with hormonal contraception was reported by cca one third and with a condom by two thirds of respondents. Among younger men and women there are more users of hormonal contraception and condoms. Only 5% of the examined men and 4% of the women opposed any type of contraception, almost one quarter of respondents use only so-called "natural methods" and almost three quarters of the respondents consider them an essential part of sex life. The attitudes of atheists and junior and more educated women are more liberal.     

Attitudes toward abortion in Thailand: a survey of senior medical students

A majority of senior Thai medical students favored induced abortion in many circumstances not now considered legal. While 20 percent would not perform abortions for any reason, many of these would refer cases to colleagues. Independent variables consistently and significantly influencing attitudes conservatively were: female sex, certain medical schools attended, larger ideal family size, intention not to teach in a medical school as a career, having a father in unskilled or semiskilled or work, never having witnessed an illegal abortion, and never having been asked to find an abortion practitioner for a friend. A random reordering of the questions did not affect reports of attitudes toward or willingness to perform induced abortion.     

The role of the nurse manager in ambulatory care: results of a national survey

Increasing complexity in ambulatory care settings requires nurse managers who can function at higher levels. Little agreement currently exists regarding the role expectations and academic preparation needed for nurse managers in ambulatory care settings. The majority of surveyed ambulatory care nurse managers (40%) have an AD or diploma as their highest level of academic preparation, and have thus acquired the majority of their management skills in the practice setting. The authors express concern that there are pressures to employ non-nurses as managers in ambulatory health care settings and that ambulatory nurse managers are often seen as not needing advanced academic preparation. A wide variety of settings including university and community hospitals, outpatient departments, physician group practices and HMOs, currently employ nurse managers in their multidisciplinary ambulatory care sites. The majority of ambulatory care nurse managers describe their model of care as either the medical model or the functional model.     

The practice of medical and surgical synovectomy: a UK survey

BACKGROUND: QT dispersion (QTd = QTmax-QTmin) measured as interlead variability of QT interval reflects the spatial inhomogeneity of ventricular repolarization times, and increased QTd may provide a substrate for malignant ventricular arrhythmias. Ischemia is associated with regional abnormalities of conduction and repolarization. HYPOTHESIS: This study aimed to investigate the effect of acute ischemia on QTd during successful percutaneous transluminal coronary angioplasty (PTCA). METHODS: Forty-three patients (10 women, 33 men, mean age 56 years) were enrolled in the study. Electrocardiogram (ECG) recordings were taken before PTCA and during balloon inflation period. QT maximum (QTmax), QT minimum (QTmin), and QTd (QTmax-QTmin) values were calculated from the surface ECG. RESULTS: There was no difference among QTmax values (p = 0.6). Mean QTmin during balloon inflation was lower than before PTCA (368 +/- 45 vs. 380 +/- 41 ms, p = 0.002). The difference between QTd values before and during balloon inflation was statistically important (65 +/- 9 vs. 76 +/- 10 ms, p = 0.001). This difference is caused by a decrease in QTmin during balloon inflation. CONCLUSION: Acute reversible myocardial ischemia induced by balloon inflation causes an increase in QTd value, and this increment is the result of a decrease in QTmin interval. Therefore, QTd may be a marker of reversible myocardial ischemia.
