Introduction: Pseudomonas aeruginosa respiratory infections are associated with poor respiratory function, low quality of life, and a high relapse rate., Methods: A 6-year prospective study (2000-2005) was carried out. Patients with P. aeruginosa respiratory infection admitted to a Hospital at Home service for parenteral antibiotic treatment were enrolled in the study. Clinical response to treatment, relapse, and relapse-free time, were analyzed as primary endpoints., Results: A total of 111 episodes were recorded in 81 patients. Bronchiectasia was the most common associated disease (57%). Ceftazidime and tobramycin were the first-line therapies used (61%). The average length of stay was 14 days. Among the total, 80% of patients had severe/very severe respiratory obstruction, and 35% were culture-positive at the end of treatment. Median follow-up to relapse was 144 days; 65% of episodes relapsed. Relapse was associated with bronchiectasia, aerosol therapy, and more severe respiratory obstruction. In the patients with severe/very severe obstruction, there was a decrease in relapse-free time from 1080 to 139 days, in those with positive culture at the end of therapy from 248 to 78 days, and in those with resistance to any antipseudomonal antibiotic, from 390 to 97 days. On multivariate analysis, severity of respiratory obstruction and the antibiotic resistance were independent risk factors for relapse., Conclusion: Patients infected by P. aeruginosa in poor clinical condition or showing resistance to any antipseudomonal antibiotics have a higher probability of relapse, and a shorter time to relapse than other patients with this infection. The Hospital at Home Service is a good approach to reducing the long-term hospital stay in these patients.

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 2003., 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 3,858 patients that belong to twenty-one hospitals. Mean age from those adults 66.2 +/- 18.9 years, and from those younger than 14, 6.0 +/- 4.3 years. Neurological and neoplasic diseases were the diagnostics more frequents (38.9% and 37.4%, respectively). Oral nutrition was the preferential rout used for the enteral nutrition (54.7%) followed by naso-enteral tube (26.6%), and only in 17.6% we used ostomy tubes. Polymeric was the enteral formula mainly utilized (80.1%). The mean time on HEN was 6.6 +/- 4.3 months; the 28.8% of patients stayed in the treatment for less than 3 months, 21.2 % between 3 and 6 months, and 50.0% more than 6 months. Patients were followed mainly by Nutritional Support Unit from the reference hospital (73.1%). While the reference hospital supplies the material (62.4%), reference hospital pharmacy (46.8%) and public pharmacies (32.0%) provides the enteral formula. Complications related to enteral nutrition included change of enteral tube (44.5%), gastrointestinal complications (30.5%), mechanical complications (21.7%), and the metabolic one (3.3%). These complications were followed by 0.02 hospitalizations/patient. At the end of the year, 54.7% of patients were in the HEN programme, and in 35.2 % HEN was finish due to accept oral conventional alimentation (49.2%) or by deceased of patients (40.9%). While 26.6% of the patients were confined to bed or armchair, 19.7 % no or light discapacity degree was observed., Conclusions: We found a persistence of these treatment in our country. 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.

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.

The case of a 60-year-old patient who was repeatedly admitted for ascitic decompensation secondary to hyperflow portal hypertension provoked by congenital arteriovenous malformation of the superior mesenteric artery is presented. Diagnosis was performed by arteriography. Surgical treatment was conducted with total resection of the malformation thereby achieving complete resolution and normalization of portal pressure. The literature is reviewed and the pathophysiologic mechanism as well as the clinical manifestations, diagnosis and treatment are discussed.
