[Characterization of rhizobia causing nodules on leguminous trees native to Uruguay using the rep-PCR technique].
Methods for identifying and following microorganisms in the environment such as soils, water and plant association have been highly developed in recent years. In this study, we used rep-PCR for the characterization of Rhizobium bacteria isolated from legume trees native of Uruguay which permitted to follow them in plant inoculation assays. Among the primers used, ERIC and BOX1AR, the latter allowed the differentiation of isolates from different legumes and the finding of a high level of homology among rhizobia that nodulate the same legume species. Besides, it demonstrated that the profiles of the isolates recovered from nodules of Acacia caven, were identical to the ones used as inoculants; this confirmed the efficiency of these methods to follow these diazotrophs in the environment.

[Barcelona Bipolar Eating Disorder Scale (BEDS): a self-administered scale for eating disturbances in bipolar patients].
INTRODUCTION: The presence of eating disorders in bipolar population is not rare, with rates over 10 %, according to the few available epidemiologic studies, however the literature on this issue is still scarce. An even higher percentage of bipolar individuals suffer from serious problems related to eating behavior without fulfilling criteria for DSM-IV eating disorder. METHODS: The Bipolar Eating Disorders Scale (BEDS) was designed on the basis of the existing eating scales, adjusted to the characteristics of bipolar disorders from the complaints of our sample of patients (n=350). Subsequently, a group of experts made the selection of the most representative and independent items in order to obtain a short, 10-item scale, aimed at assessing the intensity and frequency of eating dysfunctions in the bipolar population and not at diagnosis. We administered the scale to a healthy control group (n=55) to evaluate feasibility and to determine the cut-off score. RESULTS: The BEDS is a 10-item simple, self-administered scale. Average time of completing this scale is about 1.13 min (1 min, 21 seconds) +/-26 seconds. Median score was 6 and the mean score was 6.6 with a standard deviation of 3.7, this being the reason why the cut-off point was found to be around 13 points. Patients receiving scores over 13 may require an individualized intervention to evaluate which were the main difficulties and to propose treatment. CONCLUSIONS: The BEDS allows for a rapid and effective evaluation of both the intensity and the frequency of eating dysfunctions in bipolar patients in order to perform an adequate intervention for the specific needs of each one of the patients.

[National Registry of Home Parenteral Nutrition of the year 2001].
AIM: We analyse the registered data of home parenteral nutrition (HPN) in our country during the year 2001. METHOD: The data were collected through a previously designed questionnaire. Apart from epidemiological information, the form includes the disease to prescribe this treatment, the specific nutritional treatment used and its duration, access path, complications and readmission rate in hospital, follow-up of the treatment, and progress. All data were processed and analysed by the co-ordinating team. RESULTS: Seventeen hospitals participated, and 66 patients were enrolled. Middle age was 5.5 +/- 4.9 years for patients < 14 years old, and 49.2 +/- 15.8 years for those > or = 14 years old. The more prevalent diagnosis were: ischemic bowel (28.9%), neoplasm (22.7%), radiation enteritis (12.1%), motility disorders (4.5%) and Crohn's disease (4.5%). The mean time on HPN was 8.4 +/- 4.5 months. Tunnelled catheter was the preferential route (62.1%), followed by the implantated one (33.3%). The intermittent method (nocturnal) was preferential (81.8%). Patients receive the formula, mainly from hospital pharmacy (75.7%). The complications related to nutrition (1.3/patient) included the infections (0.46 sepsis/patient, and 0.19 catheter contamination/patients), mechanic (0.15/patient), metabolic (0.1/patient) and electrolytic disorders (0.07/patient). The readmission rate, for nutritional problems, was 1.34/patient. At the end of the year, 74.2% of the patients remained in the HPN program, and 25.8% abandoned the treatment (due to death: 52.9%, and to progress to oral feeding (25.3%). CONCLUSIONS: This review illustrates that the registration of HPN patients in our country is standing (1.65 patients/10(6) habitants), that vascular pathology is the more frequent diagnoses in HPN patients, and the rate of readmission and complications and the behaviour is similar to other series making this as a safe treatment in our place.

[Home Enteral Nutrition: National Registry 2001].
GOAL: The NADYA-SENPE Working Group analyzed the registered data of patients on Home Enteral Nutrition (HEN) in our country, during year 2001. MATERIAL AND METHODS: The data were collected through a closed questionnaire included on our web site (www.nadya-senpe.com). Apart from epidemiological information, the form includes the indication to prescribe this treatment, the specific nutritional treatment used and its duration, access path, complications and readmission rate in hospital, follow-up of the treatment, patient's quality of life and progress. All data were processed and analyzed by the coordinating team. RESULTS: Twenty two hospitals participated and 3,458 patients, aged 5.6 +/- 4.0 y for those younger than 14 y, and 67.1 +/- 19.5 y for those older than 14 y, were enrolled. Of these patients, 43.4% were diagnosed with neurological diseases and 33.5% with cancer. The mean time on HEN was 6.5 +/- 4.5 months. Oral nutrition was the preferential route (54.5%), followed by nasoenteral tube (32.3%), and in 13.3% ostomy tubes were placed. Polymeric was the formula composition mainly used (85.9%). Patients were followed (71.1%) by the hospital reference Nutritional Support Unit. The complications related to nutrition included mainly the gastrointestinal (0.16 complications/patient), and the mechanical one (0.15 complications/patient). At the end for the year, 48.3% of the patients were in the HEN program, and in 33.3% HEN was finish due to different reasons. In 22.9% of the patients no, o light, discapacity degree was found. CONCLUSIONS: Neurological diseases and cancer were the more frequent diagnoses in HEN patients. Oral access was the higher feeding route due, probably, to the high prevalence of cancer patients. In spite of the elevated prevalence of neurological diseases, a few number of patients, as previous years, were feed with ostomy tube. Due to the few complications observed, HEN is a safe treatment in our country.

[Evaluation of 2 techniques for ventilation support during single-lung ventilation].
In a group of 22 patients undergoing thoracotomy we compared two techniques of ventilatory assistance to the nondependent lung during single lung ventilation. We simultaneously administered a 0.5% FiO2 to the dependent lung. We used a CPAP system with continuous O2 flow limited by an underwater valve at a pressure of +5 cmH2O. We performed 33 ventilatory assistances: in 15 cases to the nondependent lung (CPAP group) and in 18 patients to the lower lobe of the nondependent lung (lobar CPAP group). Evaluation of both techniques was performed by means of arterial blood gas measurement and the mean values were compared using the student's t test. During single lung ventilation the PaO2 in CPAP group increased from 85.86 +/- 22.28 mmHg to 155.52 +/- 59.54 mmHg (p less than 0.001) and in the lobar CPAP series it increased from 88.75 +/- 24.34 mmHg to 122.36 +/- 43.21 mmHg (p less than 0.01). In 11 out of the 22 patients we firstly applied the lobar CPAP and thereafter the CPAP to the whole lung in order to compare the efficacy of both techniques in the same patient. The PaO2 during single lung ventilation was 86.9 +/- 22.7 mmHg and it increased to 111.1 +/- 37.9 mmHg after lobar CPAP (p less than 0.01) ant to 163.3 +/- 64 mmHg after total lung CPAP ventilation (p less than 0.001). Our results confirm the usefulness of both techniques and they indicate that CPAP to the whole nondependent lung is the most effective.

[The year 2002 national register on home-based parenteral nutrition].
AIM: To report on the results of the Registry on Home-based Parenteral Nutrition (HPN) of the NADYA-SENPE working group, corresponding to the year 2002. MATERIALS AND METHOD: Compilation of the registry data loaded by the Units in charge of HPN patients care. It consists of an on-line registry available to the registered users of the group's web page (www.nadya-senpe.com). Epidemiological, diagnostic, access route, complications, hospital admissions, degree of disability, and course until December 31st of 2002. RESULTS: Data from 74 patients were gathered (56.8% women and 43.2% men), from 18 hospital centers. Mean age of adult patients was 49.4 +/- 15.5 years and 2.3-1.1 years for patients younger than 14 years (n=3 patients). Diseases that prompted the use of HPN were mesenteric ischemia (29.7%), followed by neoplasms (16.2%), radiation enteritis (12.2%), motility impairments (8.1%), and Crohn's disease (5.4%). Tunneled catheters were used in 52.7% of cases, as compared to 36.5% of subcutaneous reservoirs. Mean treatment duration was 8.7 +/- 4.4 months; 68.9% of patients remained on HPN for a duration longer than 6 months, and in 41.9% longer than one year. Patients' follow-up was mainly done from the reference hospital (87.8%), and the remaining patients (12.5%) by the home care team. In no case patients were followed by the primary care team or other specialists than the ones that prescribed nutritional support. In 94 cases there were complications related to nutritional therapy. The more frequent complications presented were infectious. These complications represented 1.84 admissions per patient. The mean number of visits was 12.9 per patient (10.2 routinary visits and 2.7 emergency visits). At the end of the year, we observed that 74.3% patients stayed in the program, whereas in the remaining 23.6% HPN had been discontinued. The main causes for discontinuation were death (52.9%), and switch to oral diet (23.5%) or enteral nutrition (11.8%). With regards to disability degree, 16.1% were confined to a wheelchair or bed, and 17.6% had no disability at all or only a mild social disability. CONCLUSIONS: We observed a sustained HPN prevalence rate in Spain (1.8 patient pmp). The main cause for its use was short bowel syndrome secondary to vascular disease, followed by cancer. Complications associated to nutritional therapy were common, especially of infectious origin.

[The year 2002 national registry on home-based enteral nutrition].
GOAL: To communicate the information available by the NADYA-SENPE Working Group from patients on Home Enteral Nutrition (HEN) in our country during the year 2002. MATERIAL AND METHODS: The data were collected through a closed questionnaire included in the web site of the Working Group (www.nadya-senpe.com) available only by the authorized users. Variable included were: epidemiological information, the indication to prescribe this treatment, the access path, the specific nutritional formula used, the treatment duration, the complications and hospital readmission related to the nutritional treatment, the follow-up and the quality of life. RESULTS: We register 3967 patients that belong to twenty-one hospitals. Mean age from those adults 69.2 +/- 19.2 years, and from those younger than 14, 5.6 +/- 4.1 years. Neurological and neoplasic diseases were the diagnostics more frequents (39.2% and 34.6%, respectively). Oral nutrition was the preferential rout used for the enteral nutrition (53.6%) followed by naso-enteral tube (30.6%), and only in 15.8% we used ostomy tubes. Polymeric was the enteral formula mainly utilized (81.5%). The mean time on HEN was 5.8 +/- 4.4 months; the 35.7% of patients stayed in the treatment for less than 3 months, 22.4% between 3 and 6 months, and 41.6% more than 6 months. Patients were followed mainly by Nutritional Support Unit from the reference hospital (75.3%). While the reference hospital supplies the material (65.7%), reference hospital pharmacy (43%) and public pharmacies (37.3%) provides the enteral formula. Complications related to enteral nutrition included change of enteral tube (29.7%), mechanical complications (22.9%), gastrointestinal complications (22.9%), and the metabolic one (9.2%). These complications were followed by 0.02 hospitalizations/patient. At the end of the year, 49.3% of patients were in the HEN programme, and in 41.5% HEN was finish due to accept oral conventional alimentation (47.3%) or by deceased of patients. While 31.8% of the patients were confined to bed o armchair, 17.8% no o light discapacity degree was observed. CONCLUSIONS: We found a persistence of these treatment in our country (96.5 patients/million inhabitants. Neurological and neoplasic diseases were the more frequent diagnosis in patients analysed. The high prevalence of cancer patients could be the main cause of oral access for enteral nutrition. Change of enteral tube was the more frequent complication observed during this treatment.

[The year 2003 National Registry of Home-based Parenteral Nutrition].
OBJECTIVE: To report the results of the Home-based Parenteral Nutrition (HBPN) registry of the NADYA-SENPE working group, for the year 2003. MATERIAL AND METHODS: Gathering of registry data introduced by all units responsible of HBPN patient care. This an on-line registry available for authorized users of the working group web page (www.nadya-senpe.com). Epidemiological data, diagnosis, access route, complications, hospital admissions, disability degree, and course at December 31st, 2003 RESULTS: Data from 86 patients (62% female and 38% male) from 17 hospitals were gathered. Mean age of adult patients was 50.7 +/- 15.0 years, whereas for patients younger than 14 years was 2.4 +/- 1.5 years (n = 5 patients). Diseases that prone HBPN were neoplasm (21%), followed by mesenteric ischemia (20%), radiation enteritis (16.3%), motility impairments (10.5%), and Crohn's disease (4.6%). Tunneled catheters were used in 66.3% of the cases versus 29.1% of subcutaneous reservoirs. Mean treatment duration has been 8.5 +/- 4.6 months; 67.4% of patients had been on HBPN for a period of time longer than 6 months. Patient follow-up was mostly done from the reference area hospital (88.4%). In no case patient follow-up was done by the primary care team or by specialists other than those prescribing nutritional support. Nutritional support-related complications were seen in 98 occasions. The most frequent complications were infectious ones. They represented 1.60 hospital admissions per patient. The mean number of visits was 7.9 per patient (6.4 for scheduled visits and 1.5 for emergency visits). By the end of the year, we observed that 73.3% of the patients were still on the program, whereas in 23.3% HBPN had been withdrawn. The main reasons for withdrawal were decease (11 patients), and advancing to oral diet (9 patients). As for the disability degree, 13% were confined to a wheelchair or bed, and only 28% had no disability degree or only mild social disability. CONCLUSIONS: We observed a mild increase in HBPN prevalence rate in Spain (2.15 patients pmp). The main indication was cancer followed by short-bowel syndrome secondary to vascular pathology. Nutritional support-related complications were common, especially those of an infectious origin.

Treatment adherence in schizophrenia. Spanish clinical consensus.
Objective. Establish a Spanish Consensus on Therapeutic Compliance in Schizophrenia. Material and methods. An experts committee designed a specific questionnaire having 40 questions and 293 options. The questions referred to the definition and general assessment of compliance in schizophrenia, factors involved, intervention strategies in outpatients and in acute units and management of oral and long duration injectable antipsychotic drugs and other non-pharmacological therapies. First, second or third line strategy values of choice were assigned according to the answers obtained for each item. The questionnaire was sent to 383 psychiatrists of a Therapeutic Compliance Work Group. A total of 326 answers were received with an electronic system that guaranteed their confidentiality. Results and conclusions. There is maximum agreement on considering the seriousness of the compliance problem, its repercussion in relapses, the patient's course and increase in health care costs. The strategies preferred to evaluate compliance are: counting of the injectable drug administration and determination of plasma concentrations. The Consensus considers that specific intervention is necessary when the patient has already suffered several relapses due to low therapeutic compliance, when null awareness of disease is detected or if there is comorbidity with toxic consumption. Psychoeducational is the non-pharmacological strategy having the greatest consensus grade if intervention is needed. Treatments with atypical injectable, long duration, antipsychotic drugs obtain the best grade in accordance with pharmacological strategies of first choice, in different clinical situations to avoid or improve therapeutic adherence. Key words: Adherence. Compliance. Schizophrenia. Consensus.

[The value of high dose steroid therapy in obstructive uropathy caused by a tumor].
The case of an 82-years old female patient with acute renal failure secondary to tumoral obstructive uropathy by neoplasic invasion of the trigone is described. The condition was treated with urinary deviation through percutaneous nephrostomy of the left kidney which achieved an improvement in the renal function. Later, the percutaneous nephrostomy was unintentionally moved not being possible to place a new one in none of the kidneys. The patient remained anuric for 24 hours, and therapy was then instaured with high doses of intravenous steroids (6 Metyl-Prednisolone 1.5 g I.V. in 24 hours), diuresis was recovered and renal function became normalized within a few days. The mechanism of action and therapeutic usefulness of high dosage steroids in tumoral obstructive pathology is discussed.

[Results of surgery and percutaneous transluminal angioplasty in renovascular hypertension].
The results of the treatment with surgery and percutaneous transluminal angioplasty of the renal artery were evaluated in 63 adult patients of both sex, from 16 to 60 years old with renovascular hypertension due to fibromuscular dysplasia in 48 and to atherosclerosis in 15. The stenosis of the renal artery was unilateral in 47 patients and bilateral in 16. The surgical procedures more used were the aorto-renal bypass with saphenous vein in 22 patients and unilateral nephrectomy in 16. From 41 patients treated with surgery, the arterial hypertension was cure or improved after one year in 30 (73.1%). From 22 patients treated with angioplasty, cure or improved was obtained in 17 (77.2%). Satisfactory results were obtained in patients with fibromuscular dysplasia and unilateral stenosis, and poor results in atherosclerosis and bilateral stenosis, with both methods. It is concluded, that surgery and angioplasty are satisfactory therapeutic methods in the renovascular hypertension, principally when is unilateral and due to fibromuscular dysplasia.

[Rabies vaccine inactivated with ethylenimine. Duration of the immunity in dogs].
The duration-of-immunity afforded by the ethylenimine inactivated rabies vaccine produced in BHK cells with the PV strain, was studied in dogs. One hundred per cent of the dogs became serologically positive 7 days after vaccination; the same percentage was still positive 3 years after vaccination with one dose of the vaccine. A good correlation was observed between the antibody profiles as determined by the titers obtained with the mouse neutralization and fluorescent field inhibition techniques. The correlation was not as good when the number of international units per ml was determined by both tests. The best correspondence between serological response and resistance to challenge was observed when the antibodies were determined by the number of international units per ml, using the neutralization test in mice. All the dogs challenged 12 and 25 months after vaccination resisted challenge; 89% (8/9) were protected 36 months after vaccination. Inactivated vaccines can be as effective to control rabies as those prepared with modified live virus; moreover, the inactivated vaccines are more stable and safer than the latter.
