[Evaluation of a home hospitalization program in patients with exacerbations of chronic obstructive pulmonary disease].

OBJECTIVE: We carried out a randomized controlled trial to evaluate the efficacy of a home hospitalization (HH) program for patients hospitalized for exacerbation of chronic obstructive pulmonary disease (COPD). PATIENTS AND METHODS: Patients who were clinically stable and had stable arterial blood gases were randomized to the conventional hospitalization group or the HH group. RESULTS: Of the 88 patients evaluated, 40 (20 in each group) were enrolled. No differences were observed in baseline characteristics, in clinical recovery, or arterial blood gases between the 2 groups at discharge. At 1-month follow up there were no differences in mortality or in the number of readmissions. The mean length of hospitalization in patients with HH was 9.2 days (4 days in hospital and 5 days at home), compared to 12.2 days in patients with conventional hospitalization. CONCLUSIONS: Our results show that a hospital-supervised HH program including the participation of pneumologists and nursing staff allows for the recovery of patients hospitalized for exacerbation of COPD who have stable symptoms and arterial blood gases with no increase in the rate of readmission, relapse, or therapeutic failure.

[Aberrant left subclavian artery associated with Kommerell's diverticulum: chance finding in a 75-year-old patient].

The most common anomaly of the aortic arch is the occurrence of a left aortic arch with an aberrant right subclavian artery. Other, less common anomalies have also been described. These include the occurrence of a right aortic arch with an aberrant left subclavian artery that, in addition, has a diverticulum at its site of origin known as Kommerell's diverticulum. All cases described in the literature have occurred in individuals younger than 35 years of age, generally with symptoms related to tracheal or esophageal compression. We present the case of a patient diagnosed by chance with this rare anomaly at 75 years of age.

[Analysis of logistical and organizational aspects of a cruise for patients with chronic respiratory insufficiency. The RESpIRA Expedition and the COPD Cruise].

Patients with chronic respiratory insufficiency who are receiving domiciliary oxygen therapy and mechanical ventilation report great difficulty in taking complex trips involving several destinations and prolonged stays away from home. Such patients share a common need for home equipment whose technology is relatively sophisticated, a condition that limits their freedom of movement. We are referring to systems for delivering oxygen therapy and mechanical respirators. Given that such patients have problems traveling by air, we hypothesized that a cruise would be an ideal alternative, given that travel would take place in the hotel itself. A cruise would facilitate the logistics of the journey, given that the equipment would have to be set up at only one setting. Working with these assumptions, we have thus far organized two cruises for chronic respiratory insufficiency patients: the "RESpIRA Expedition" and the "COPD Cruise". Our experience shows that the organizational problems to be coped with are patient recruitment, financing and choice of itinerary. With those aspects clear, organizers must then obtain the authorization of the cruise operator, including the approval of the medical and safety personnel on board. After obtaining permission for the cruise and as soon as the organizers know how many patients will travel, a list of oxygen therapy equipment (respirators and disposable supplies) must be compiled. Finally, equipment suppliers must be found. Afterwards, all that remains is to enjoy the trip. The participation of physicians responsible for domiciliary oxygen therapy and mechanical ventilation programs is essential for making patients feel safe and for assuring solutions for technical and medical problems that might arise.

[Aerophagia due to noninvasive mechanical ventilation: a first manifestation of silent gastric carcinoma].

Noninvasive mechanical ventilation (NIV) techniques have proven useful in treating patients with respiratory insufficiency of various etiologies. The problems most frequently associated with this ventilatory technique are the appearance of nasal and oropharyngeal dryness, pressure sores where the nasal mask touches the skin, ocular irritation due to air leakage and epistaxis. Aerophagia appears in up to half the patients with NIV and may lead to discontinuing treatment. Drugs that accelerate gastrointestinal transit, changes in the respirator settings or changing the ventilatory modality may help to ameliorate the problem. When the symptoms arising from abdominal distension due to NIV are intense and persistent, the coexistence of an underlying abdominal pathology must be ruled out. We report the cases of two patients with these characteristics in whom gastroscopy revealed gastric carcinoma. We think that patients with persistent symptoms of aerophagia that cannot be controlled by the usual measures should undergo endoscopic exploration to rule out silent gastric disease.

[Analysis of the impact of Anales Españoles de Pediatría through the Science Citation Index from 1997-2000].

OBJECTIVES: To quantify the impact factor of Anales Españoles de Pediatría from 1997 until 2000 and to identify the journal's citation patterns and the topics with the greatest impact. METHODS: SCISEARCH was used to locate citations of articles published in Anales Españoles de Pediatría between 1995 and 1999. The following data were collected for each article: year of publication, authors, journal, country of publication, language, specialty or specialties, institution(s), residence of the first author and topic. The impact factor was calculated as the ratio between citations received over 1 year by articles published in Anales Españoles de Pediatría in the two previous years and the total number of articles published by Anales Españoles de Pediatría over the 2 years under study. RESULTS: The impact factor of Anales Españoles de Pediatría was 0.052 in 1997, 0.080 in 1998, 0.101 in 1999, 0.089 in 2000 and 0.064 in 2001. Citations were found in a wide range of source journals. The greatest proportion (35.6 %) were found in Spanish medical journals. Citations were made mainly by Spanish authors (62.8 %) and self-citation was moderate (14.3 %). Topics related to neurology (16.9 % of the citations received), infectious diseases (16.2 %) and neonatology (14.8 %) had the greatest impact. CONCLUSION: The impact factor of Anales Españoles de Pediatria is modest, although higher than that of some other biomedical publications included in Journal Citation Reports.

[Usefulness of induced sputum cytology in the study of central masses in elderly patients].

OBJECTIVE: To analyze the diagnostic yield of cytology obtained by means of sputum induction in elderly patients with central masses. METHODS: A total of 23 patients older than 75 years with centrally located pulmonary masses identified by computerized tomography were studied. All patients collected three spontaneously produced sputum specimens and underwent three sputum-induction sessions. Induction was considered satisfactory when the patient expectorated within the following 15 minutes. All sputum specimens were processed by May-Grünwald-Giemsa and Papanicolau staining techniques. The definite diagnostic was considered that obtained by means of bronchial biopsy or chest percutaneous aspirative puncture (PAP). RESULTS: With sputum induction, 19 patients (83%) collected satisfactory specimens and in 14 cases cytology was positive for malignancy (sensitivity 74%) and negative in five. No false-positive cases were recorded and in no patient did complications occur in association with sputum induction. The analysis of agreement between induced sputum and definite diagnosis showed a kappa index of 0.66. CONCLUSIONS: Among elderly patients with central pulmonary masses, the cytology of induced sputum should be considered as the first diagnostic procedure because of its harmlessness, remarkable sensitivity and high histologic correlation.

[Community-acquired empyema caused by Acinetobacter baumannii].

We referred a fourty-four years old male, without interesting personal history and who was accepted in the hospital due to dyspnea and fever and who was diagnosed with empyema by Acinetobacter baumannii acquired in the community; we have found no references about this in the medical literature.
