Sigma-2 receptor expression in bovine papillomavirus-associated urinary bladder tumours.

The expression of sigma-2 receptors was investigated in nine urothelial tumours of the urinary bladder of cattle. Each tumour was associated with the presence of DNA of bovine papillomavirus type-2 (BPV-2) and expression of the E5 viral oncoprotein. Five tumours were classified as low-grade carcinoma on the basis of morphological criteria and calculation of mean nuclear area (MNA) and mean nuclear perimeter (MNP). Four tumours were classified as high-grade carcinoma. Sigma-2 receptors were overexpressed in both types of carcinoma. In control normal bovine bladder tissue the density of receptors (expressed as the B(max)) was 0.37 pmol/mg of protein. Low-grade carcinomas had a mean B(max) of 1.37+/-0.32 pmol/mg of protein (range 1.03-1.86) and in high-grade carcinomas the mean B(max) was 10.9+/-2.8 pmol/mg of protein (range 8.2-14). The difference in B(max) between low- and high-grade carcinomas was statistically significant (P=0.0001).

Report of a case of discoid lupus erythematosus localised to the oral cavity: immunofluorescence findings.

Discoid Lupus Erythematosus (DLE) is a chronic disease with a typical cutaneous involvement. This pathology rarely involves mucosa: oral cavity is interested in 20 percent of DLE patients. We describe a case of oral DLE in a 50-year-old woman with an anamnesis for autoimmune disorders. This study shows the helpful role of immunofluorescence in the diagnosis of autoimmune diseases. The first diagnostic step was the clinical observation of the oral mucosa: the lesion area was erythematous, atrophic and hyperkeratotic. The patient then underwent laboratory examination. We utilized human epithelial cells (Hep-2010) for Indirect Immuno-Fluorescence (IIF). Moreover, the biopsy site for Direct Immuno-Fluorescence (DIF) and histopathological analysis was the untreated oral lesion. IIF detected an increase of Anti-Nuclear Antibody (ANA) and positivity for SSA-RO. By DIF, we observed IgG/IgA/fibrinogen along basal layer. Multiple biopsies reported signs of chronic basal damage. Steroid systemic therapy induced a considerable lesion regression. We suggest the use of immunofluorescence with the integration of further data to improve diagnosis of rare diseases and to establish a suitable therapy.

Antibiotic treatment for acute 'uncomplicated' or 'primary' pyelonephritis: a systematic, 'semantic revision'.

The definition of acute pyelonephritis is controversial. There are two contrasting approaches: (1) acute pyelonephritis is a severe infectious disease involving the kidney parenchyma, and specific imaging techniques are required for diagnosis; (2) acute pyelonephritis is a urinary tract infection, and diagnosis and therapy follow simplified clinical and laboratory pathways. In this study, recent randomized controlled trials (RCTs) were systematically reviewed and the diagnostic and therapeutic approaches to acute 'uncomplicated' pyelonephritis were analysed. Medline, Embase, Cochrane Central Register of Controlled Trials (CCTR) and Chinal were searched employing Mesh, Emtree and free terms on 'pyelonephritis'. Limits included human, period (1995-2004), and trials-reviews (where available). In total, 904 references and 175 full-text were retrieved; 29 were pertinent RCTs. Seven RCTs were added from reference lists (indexed on urinary tract infections). Imaging examinations were performed in 11 of 14 studies on children (diagnostic requisite in two) and in two studies on adults; scarring was not analysed in adults. Clinical definitions varied widely (fever >37.8 to >39 degrees C, culture titres 10(4) >10(5)). Studies on adults were limited to short-term end-points (microbiological sterilization, clinical improvement). Duration of therapy was 4-20 days. The trend was towards shorter periods of therapy, mainly on an outpatient basis; intravenous therapy, if performed, was usually limited to the first 1-3 days. For acute uncomplicated pyelonephritis, the tendency is towards 2 weeks of mainly oral antibiotic therapy. However, the recent literature on adults does not discriminate among different upper urinary tract infections nor does it provide data on renal scarring. While cost constraints point towards short-term therapies, further studies are needed to assess the prevalence and long-term effect of kidney scars.

Drug use and kidney donation: what are high-risk behaviors today?

BACKGROUND: "Social risk behaviors" are usually considered as contraindications for organ donation. The organ shortage, however, necessitates expansion of the donor pool. Reconsideration of the policy toward substance abusers may be important. Opinions of the overall population may be of use to define this cultural-sensitive issue. METHODS: A semistructured questionnaire on organ donation, including opinions on drug use (cannabis and cocaine), was administered to various groups of the general public and caregivers: high school students (liceo classico: 59 students, median age 18 years; istituto tecnico: 108, age 17); first- and fourth-year medical school (77, age 19; 46, age 22); continuing medical education (44, age 32); third-year nursing school (31, age 23); "senior citizen university" (51, age 63). RESULTS: Cannabis use was mainly accepted for kidney donation (48.6% yes, 26.6% no, 29.8% uncertain/blank), but cocaine use was not (22.1% yes, 44.2% no, 33.7% uncertain/blank). In the univariate analysis, opinions differed according to age, sex, and belonging to the health care teams upon multivariate analysis being a member of the health care team was the strongest predictor of responses (P<.01). CONCLUSION: It is difficult to define social risk behaviors. Since opinions are important for organ donation, further studies and discussion are needed to periodically analyze our policies.

Is male homosexuality still a cultural taboo for kidney donation?

BACKGROUND: Among the so-called social risk behaviors, male homosexuality is probably one of the most interesting and difficult taboos. Because of changing attitudes of the general population toward irregular sexual behaviors, often considered as markers of unhealthy life styles, there is a need to reconsider at least the most important one-homosexuality. METHODS: A semistructured questionnaire included opinions on homosexuality with respect to kidney donation: Would you consider a male homosexual as a kidney donor? If you were on dialysis, would you accept a kidney from a homosexual donor? This instrument was administered to various groups of the general public and caregivers: high school students (Liceo Classico: 59 students, median age 18 years; Istituto Tecnico: n=108, median age 17); first and fourth year of medical school (n=77, age 19; 46, age 22); continuing medical education (n=44, age 32); third year of nursing school (n=31, age 23); "senior citizen university" (n=51, age 63). RESULTS: Male homosexuality was well accepted for kidney donation (71.6% yes, 9.6% no, 18.8% uncertain/blank). However, the opinions were different among the groups with male students of a technical institute showing discrimination against male homosexuals. In the univariate analysis, opinions differed according to age, gender, and belonging to the health care team. In the multivariate analysis, the latter was the strongest predictor (P<.01). The specific threats for the health are not well known, even among the caregiver population. CONCLUSION: It is difficult to define the role of homosexuality among the so-called social risk behaviors. Negative attitudes existed in some subsets of the population.

Comparison between 24-h proteinuria, urinary protein/creatinine ratio and dipstick test in patients with nephropathy: patterns of proteinuria in dipstick-negative patients.

OBJECTIVE: Three main tests are commonly employed for the measurement of proteinuria: the dipstick test, the urinary protein/creatinine ratio (P/C) and the 24-h urine collection. The aim of this study was to evaluate the correlation between these methods, comparing linear regression and ROC curve data. MATERIAL AND METHODS: A total of 297 consecutive outpatients with different renal diseases were included in the study. Twenty-four-hour proteinuria was considered the reference test. RESULTS: A high degree of correlation was observed between all the tests (p<0.0001), the highest regression coefficient being between 24-h proteinuria and P/C (R=0.82), and the lowest between P/C and the dipstick test (R=0.72). The dipstick test failed to detect pathological proteinuria in 94 patients (31.6%). Therefore, in these subjects, the patterns of proteinuria were assessed by immunofixation and sodium dodecyl sulphate (SDS) electrophoresis. CONCLUSIONS: Our data strongly support the use of urinary P/C for the detection of proteinuria, at least in nephrology units, where the prevalence of proteinuria is likely to be high.

Development of kidney scars after acute uncomplicated pyelonephritis: relationship with clinical, laboratory and imaging data at diagnosis.

BACKGROUND: Acute pyelonephritis is a potential cause of kidney scars. AIM: To evaluate the relationship between clinical, laboratory and imaging data and the development of kidney scars in acute pyelonephritis. METHODS: All consecutive patients hospitalized for acute uncomplicated pyelonephritis in our nephrology unit from June 1996 to June 2004 were considered: 58 females, median age 25.6 years (16-52). Diagnosis of pyelonephritis required parenchymal lesions shown by CT or NMR scan. RESULTS: The lesions were bilateral in 17.2% (10/58) patients, unilateral, but multifocal in 81.0% (47/58); at CT or NMR, 65.5% of the lesions were classified as simple, 19% with tendency to colliquation and 15.5% abscessual. The median interval between first symptoms and diagnosis was 5 days (1-25); at referral, only 20.7% had a positive urine culture and 94.8% (55/58) had undergone previous antibiotic treatment. The therapeutic protocol required intravenous therapy for > or = 2 weeks, followed by 2-4 weeks of oral therapy. At 6-8 months, the prevalence of kidney scars was 29.3%. Their development was highly correlated with the type of lesions at diagnosis (highest risk with abscessual lesions; uni- and multivariate analysis). No other clinical or laboratory marker (age, fever, positive cultures, levels of acute phase reactants, interval between onset and diagnosis) was correlated with the outcome (scars). CONCLUSIONS: The type of lesion at diagnosis of acute uncomplicated pyelonephritis is highly correlated with the development of kidney scars. Further studies are needed to test the therapeutic schedules tailored according to the imaging data.

Diagnostic accuracy of the serum profile of gastric mucosa in relation to histological and morphometric diagnosis of atrophy.

BACKGROUND: Histology is the gold standard for diagnosis of atrophy but is hampered by observer variation. A reliable method to overcome this issue is morphometric analysis of gastric mucosa. Serum pepsinogens and gastrin have been proposed in the diagnostic work-up of gastric atrophy although diagnostic accuracy of these tests is considered unsatisfactory. AIM: To evaluate the diagnostic accuracy of gastric serum profile in relation both to morphological and morphometric diagnosis of gastric atrophy. METHODS: Ninety-four dyspeptic out-patients underwent upper endoscopy and evaluation of serum levels of PGI, PGII and 17-gastrin. Diagnostic accuracy of gastric serum profile was tested by receiver operating characteristic curves and by evaluation of sensitivity and specificity in relation to both histology and morphometric analyses. RESULTS: As far as concern to histological evaluation, only PGI/PGII ratio showed an acceptable diagnostic accuracy in discrimination of gastric atrophy, while, when morphometric analysis was considered as reference, both serum PGI level and PGI/PGII ratio showed an excellent performance. However, both PGI and PGI/PGII ratio showed low sensitivity and high specificity. CONCLUSIONS: Serological gastric profile corresponds better with the morphometric diagnosis of atrophy, even if, because of the low sensitivity, today this could only be used as screening test of chronic atrophic gastritis.

CKD patients and erythropoietin: do we need evidence-based informed consent?

BACKGROUND: Consent to therapy is increasingly requested in the form of ''informed consent''. OBJECTIVE: To validate an evidence-based informed consent form for erythropoietin (EPO) therapy and to evaluate patient opinions about the informed consent approach. METHODS: An evidence-based informed consent form was developed as part of the Evidence-Based-Medicine course at the Medical School of Turin, Italy. It was validated by anonymous questionnaires (0-10 analogical scales and open answers) administered to patients at different stages of CKD (19 pre-ESRD, 26 hemodialysis, 12 transplant patients) attending an outpatient unit of the University of Turin, to 8 nurses, and to 26 medical students. RESULTS: All individuals filled in the questionnaire. Interest in a detailed explanation of the therapy was high (median 9), as was comprehension (median 9), with no differences between patients with regard to disease stage (pre-ESRD vs. RRT) or educational level. Prior knowledge of the therapy was affected by the educational level (p=0.013 for the advantages and p=0.004 for the side effects) and the professional role (patients vs caregivers: p=0.009 for the advantages and p<0.001 for side affects); patient knowledge of the advantages (median 6) tended to increase as the disease progressed (p=0.015). The most common response by patients was that informed consent was necessary for all drugs (35.1%); 73.1% of the caregivers considered it necessary only for severe side effects. The preferred modality of consent was discussion with the caregiver during the clinical controls (42% of all cases). CONCLUSIONS: Patient interest in and comprehension of an informed consent form with a detailed explanation of the therapy was high; the caregiver's opinion was still the most valued teaching tool.

Play-back theatre, theatre laboratory, and role-playing: new tools in investigating the patient-physician relationship in the context of continuing medical education courses.

AIM: The aim of this study was to report on the validation of a role-playing approach, using play-back and theatre laboratory in the context of a continuing medical education (CME) course on predialysis and transplantation, to discuss the patient-physician relationship. METHODS: The course was developed with the help of a theatre director. The role-playing 2-day course was designed to be highly interactive for a small group (15-20 participants), based on a core of case reports (dialysis, transplantation, and return to dialysis after graft failure). Two stages were included: play-back theatre in which experiences told by the participants were mimed by a group of actors, and theatre laboratory in which different aspects of voice and touch were explored. Opinions were gathered by an anonymous semistructured questionnaire completed by all participants. RESULTS: The course obtained a high score from The Ministry of Health (14 credits, 1 per teaching hour). The opinions of the 18 participants were highly positive; all liked the courses. Sixteen of 18 asked to repeat the experience. The strong emotional involvement was an advantage for 15 of 18, sharing emotional aspects of the profession for 10 of 18, and usefulness in clarifying opinions on "dark sides" of our profession for 10 of 18. CONCLUSION: The positive opinions recorded during this experience, the first experiment with a "psycho-theatrical approach" developed in a CME course in our country, suggest the benefit of implementing nonconventional, educational approaches in a multidisciplinary discussion of the patient-physician relationship in transplantation medicine.

Diffuse vascular damage in a transplanted kidney: an indication for nuclear magnetic resonance?

Vascular lesions are an increasing challenge after renal transplantation due to the wider indications for recipients and acceptance criteria for donors. Diagnostic approach and prognostic interpretation are still matter of controversy. The case reported herein may summarize some of the issues in this regard. A 54-year-old woman, on renal replacement therapy since 1974, and a kidney graft recipient from 1975 to 1999, received a second graft in 2001. The donor age was 65 years (cold ischemia 22 hours; two mismatches). The early posttransplant follow-up was characterized by delayed graft function, hypertension, and diabetes. During the initial hypertension workup, renal graft ultrasound (US) Doppler demonstrated increased vascular resistances, stable over time (resistance index 0.74 to 0.77); renal scintiscan displayed homogeneously parenchymoa and angio-magnetic resonance imaging (MRI), an homogeneous parenchymal vascularization. Initial immunosuppression with tacrolimus and steroids was modulated by adding mycophenolate mofetil to taper tacrolimus (to reduce nephrotoxicity and hypertension). Despite this, kidney function slowly deteriorated; serum creatinine reached 3 to 3.5 mg/dL by the second year. After a severe hypertensive crisis with unchanged scintiscan and US doppler examinations, angio-MRI revealed the almost complete disappearance of parenchymal enhancement beyond the lobar arteries. A renal biopsy confirmed the severe vascular damage. The patient was switched to rapamycine and a low-dose of an angiotension converting enzyme (ACE) inhibitor. She did relatively well (serum creatinine 2.2 to 3 mg/dL) for 6 months, when rapid functional impairment forced her to restart hemodialysis. This case, almost paradigmatic of the problems occurring when the rigid vasculature of long-term dialysis patients is matched with "marginal kidneys," suggests that MRI may be a sensible good to define vascular damage in the grafted kidney.

Asclepiad's cock: a patient-physician association is a useful tool for educational programs in nephrology, dialysis, and transplantation.

BACKGROUND: The negative impact of the mass media, the lack of information, and the request for in-depth knowledge are the basis for the present need for educational programs on transplantation, brain death, and chronic kidney diseases end-stage renal disease; (ESRD). The aim of the present article was to critically review the activities performed by Il Gallo di Esculapio, a nonprofit association, in the education on the different phases of ESRD. The associates are physicians and patients, and the activities are integrated institutionally. METHODS: This report is a narrative review of the material produced and performed by Il Gallo di Esculapio ONLUS in 1996-2004. RESULTS: The two main activities developed were book writing and an educational program. Eight books for patient education were written on different aspects of dialysis, transplantation, and ESRD. Most were designed as theses of the Medical School. Cooperation with patients was important in all cases and fundamental for the collection of interviews. EDUCATION: A 4-hour educational program on transplantation started in 2000-2001 (1 high school was involved). The checklist originally included only transplantation and organ donation, but progressively gave space also to dialysis, ESRD, and social health care problems. In 2003-2004 the program involved 67 high schools. The association coordinated progressive patient involvement. CONCLUSION: Small, nonprofit patient-physician associations linked with the University allow enrolling resources for educational activities to often-neglected parts of the medical profession.

Making a movie on kidney transplantation: a medical school graduation thesis to explain kidney transplantation from students to students.

The aim of this study was to report on the production and the opinions of a video movie on transplantation and organ donation. The video was developed by a medical school student with the help of the students and teachers of a high school for applied arts. For this task, the making of the video was included in the high school program of the participating class. The students were tutored by their photography teacher. The video movie lasts about 50 minutes. Each "scene" lasts no more than 5 minutes, to avoid reducing the attention level. The choice of a nonmedical frame helped to have some moments to digest the technical information and to stress the importance of the patient-physician relationship. The video was employed as a part of small-group lessons in the nephrology course. A semistructured anonymous questionnaire gathered the opinion of 65 students at the end of the lessons. Student satisfaction was high; the median score was the highest (8, range 6 to 10) for the lesson based upon the movie, as compared with the conventional ones on chronic kidney disease or dialysis (7, range 5 to 10). As far as the authors know, this is the first experiment of a multimedia approach, dedicated to medical and nonmedical targets, developed as a graduation thesis in an Italian Medical School. In conclusion, the positive opinions of the students, who highly appreciated the peer-developed message, may suggest implementing such nonconventional educational approaches to support human resources and enthusiasm for kidney transplantation among the new generations.

Continuing education in medicine: a useful tool for nurses' empowerment in renal transplantation.

BACKGROUND: Continuing Education in Medicine (CEM) underlines the importance of updates and information for the health care team. Our aim was to describe the organization and results of a CEM course "educate to organ donation" that involved the nursing team in an educational experience with high school students. The course consists of theory (4 hours; the physician-patient relationship, the educational role of the nurse, the teaching policy, checklist, and results of a school education program) and practice (10 hours; the attendants join the teaching team in the classrooms and in the plenary session). Analysis of anonymous questionnaires performed after the course contained semistructured questions and analog scales. RESULTS: The first acknowledgment came from the Cabinet of Public Health, which gave the maximum number of credits (14 for 14 education hours). PARTICIPATION: presently 40 nurses, about 40% of those working in the renal unit (over 30 CEM courses are available in the hospital). Satisfaction: Overall score was median 8.5 (6 to 10) including teaching materials = 8 (4 to 10). Among the theoretical part, the lesson on patient-physician relationship obtained the highest score. The main drawback was the shortness of the practical part. The classroom meeting achieved a median score of 9.5 (7 to 10), the general session = 9 (5 to 10). All but one nurse registered for an "advanced" course, giving more time to the practical part (20 hours). CONCLUSION: CEM may represent an important way to deliver education on transplant-related issues to patients and to the general population.

Tailored dialysis start may allow persistence of residual renal function after graft failure: a case report.

BACKGROUND: Restarting dialysis after kidney transplantation is a critical step with psychological and clinical implications. Maintenance of residual renal function a known factor affecting survival in chronic kidney disease, has so far not been investigated after a kidney transplantation. THE CASE: A 54-year-old woman who started dialysis in 1974 (first graft, 1975-1999) received a second "marginal" kidney graft in February 2001 (donor age, 65 years). Her chronic therapy was tacrolimus and steroids. She had a clinical history as follows: nadir creatinine level of 1.5 mg/dL, moderate-severe hypertension, progressive graft dysfunction, nonresponsiveness to addition of mycophenolate, tapering FK levels, and a rescue switch from tacrolimus to rapamycin. From October to December 2003, the creatinine level increased from 2-2.8 to 7 mg/dL. Biopsy specimen showed malignant and "benign" nephrosclerosis, posttransplantation glomerulopathy, and tacrolimus toxicity. Chronic dialysis was started (GFR <3 mL/min). Rapamycin was discontinued. Dialysis was tailored to reach an equivalent renal clearance of >15 mL/min (2 sessions/wk). Blood pressure control improved, nephrotoxic drugs were avoided, and fluid loss was minimized (maximum 500 mL/hr). By this policy, renal function progressively increased to GFR >10 mL/min in May 2004, allowing a once or twice weekly dialysis schedule, with good clinical balance, and obvious advantages for the quality of life. CONCLUSION: This long-term patient, who restarted dialysis with severely reduced renal function, regained sufficient renal function to allow once weekly dialysis. Thus, careful tailoring of dialysis sessions at the restart of dialysis may allow preservation of residual kidney function, at least in individuals for whom a subsequent graft is unlikely.

EPO or not-EPO? An evidence based informed consent.

BACKGROUND: Informed consent is crucial in therapeutic choices; however, the forms presented to patients are often locally developed and information may not be homogeneous. OBJECTIVE: To prepare an evidence-based model for informed consent, applied in the case of erythropoietin therapy (EPO) as a teaching tool for medical students. METHODS: Methodological tools of Evidence-Based Medicine (EBM) were developed within the EBM Course in the Medical School of Torino, Italy, as problem solving and patient information tools (5th year students work in small groups under the supervision of statisticians, epidemiologists and experts of internal medicine--nephrology in this case). RESULTS: Methodological and ethical problems were identified: in the pre-dialysis field, evidence from randomized clinical trials (RCT) is scant; how to use evidence gathered in dialysis? How to deal with implementation? How with the mass media? Do we need to discuss the drug choice with the patients? How to deal with rare and severe side effects?). The "evidence" was searched for on Medline/Embase, by using key-words and free terms. About 680 papers were retrieved and screened. Forms available on the Internet were retrieved and a general scheme was drawn: it included 5 areas: title, aim and targets (patients and family physicians); search strategies and updating; pros and cons of therapy; alternative options; open questions. CONCLUSIONS: EBM may offer valuable tools for systematically approaching patient information; the inclusion of this kind of exercise in the Medical School EBM courses may help enhance the awareness of future physicians of the correct communication with patients.

Maintenance of residual renal function 10 years after the start of hemodialysis: the advantage of tailored schedules?

Maintenance of residual renal clearance is a clinical advantage, protecting against the long-term effects of uremia: although demonstrated in peritoneal dialysis, the strategies in hemodialysis are less clear. This case suggests that dialysis schedules individualized on the basis of renal clearances may help preserve residual function. SB is a 58 year-old male who started dialysis in emergency (creatinine 30.7 mg/dL) in 1993. He had a history of gout, small shrunken kidneys and moderate hypertension. The clinical diagnosis was vasculointerstitial nephropathy. Eighteen months after starting hemodialysis on a conventional thrice weekly schedule, the patient was switched to 2 sessions/week (creatinine clearance increased to 6 ml/min). Thereafter, clearances were checked in alternate months and treatment was tailored to an equivalent renal clearance > or =12 ml/min (1-2 sessions, 2-3.30 hours/week). Ten years after beginning dialysis, he is on a twice weekly schedule (3.30 hours), is normotensive, works full-time and does not want to go on a transplant waiting list.

Opinions on renal transplantation and organ donation in high school students in two large northern (Torino) and southern (Napoli) Italian cities.

UNLABELLED: Organ shortage for transplantation has focused attention on educational interventions. Italy is a nonhomogenous country whose cultural and economic differences are reflected in the health-care system: dialysis is mainly public in the north versus private in the south; and transplantation rates display a wide range from 3.4 to 37.8 per million people in 2002. The aim of the present study was to analyze the opinions of population of high school students (last two years) in two large cities: northern (Torino) and southern (Napoli) Italy, as a knowledge base for a randomized controlled trial on the efficacy of educational interventions on renal replacement therapy and organ donation, targeted to high school students. METHODS: This preliminary study included eight public high schools that completed a first and anonymous semistructured questionnaire. Five hundred and eighty nine questionnaires were retrieved in Torino and 539 in Napoli. In both cities most students answered that they would give a kidney to a brother, sister, or partner needing dialysis (Torino: yes 80.6%; no 2.2%, uncertain-blank 17.2%; Napoli: yes 86.1%, no 1.1%; uncertain-blank 12.8%). Only 36.3% of the students in Torino and 37.7% in Napoli answered that they would consent to organ donation, if they had to choose for a strict relative with brain death. Opposition was 28% in Torino and 23.7% in Napoli; 35.7% in Torino and 38.6% in Napoli were blank-uncertain. These data underline the need for detailed information on the opinions of the overall population as basis for tailored educational campaigns.

Efficacy of an educational program on dialysis, renal transplantation, and organ donation on the opinions of high school students: a randomized controlled trial.

AIM: Organ shortage is a rate-limiting factor for transplantation. The aim of this study was to evaluate the impact of an educational program targeted to high school students on opinions concerning organ donation. METHODS: Sixteen public high schools in Torino, Italy, were randomized (2001 to 2002) as interventions (n = 8) or controls (n = 8). Intervention was composed of first questionnaire, first lesson (one to two classes; 2 hours, by a trained nephrology fellow); second lesson (all classes together; coordinated by a nephrologist, with patients and trainees); second questionnaire. Control included questionnaires. Statistical analysis compared the opinions in the questionnaires after stratification for age, sex, and type of school. RESULTS: Fourteen schools completed the program (seven interventions: 937 first and 808 second questionnaires; controls: 739 and 659). Television (82.5%) and newspapers (43.2%) were the main sources of information; knowledge on renal transplantation (grafts feasible per patient, average duration) was low; only 12.2% of the students gave correct answers. The opinions on living donation were highly positive (76.8%) with no difference in control, intervention schools, first and second questionnaires, according to sex, age, or type of school. The opinions on cadaveric transplantation were affected by the educational intervention with a drop in negative answers (from 33.7% to 16%), with an increase in positive (from 31.5% to 42.9%) and in uncertain ones (from 34.8% to 41.1%) among the intervention schools; 98% of the students appreciated the program. CONCLUSION: The positive effect on student opinions suggests the need to develop educational approaches as a part of our routine clinical work.
