[Appropriate hospitalization in patients with human immunodeficiency virus infection according to the Appropriateness Evaluation Protocol criteria. Factors related to the inappropriateness].

BASIS: To know the factors associated with the inadequate admissions in patients with human immunodeficiency virus (HIV) infection. PATIENTS AND METHODS: The adaptation of 710 hospital admissions of patients with HIV infection through the Appropriateness Evaluation Protocol criteria in two hospitals of the Comunidad Valenciana since 1995 to 1997 was analyzed. RESULTS: One hundred twenty-eight (18%) admissions were considered inadequate. The proportion of inadequate admissions was significantly higher in patients admitted because of constitutional syndrome (OR: 4.12; CI 95%: 2.11-8.05), or because of digestive symptoms (OR: 2.33; CI 95%: 1.46-3.88), and in patients admitted in facilities without day hospital (OR: 2.38; CI 95%: 1.39-3.89). Furthermore, other situations associated with the inappropriateness were the patients with a disease not related to AIDS (OR: 3.13; CI 95%: 1.93-5.08), the patients with oral or esophageal candidiasis (OR: 6.25; CI 95%: 3.08-12.7), the patients with a hospital stay less than 8 days (OR: 2.55; CI 95%: 1.57-4.01), or the patients who no died (OR: 3.61; IC 95%: 1.20-10.82). CONCLUSIONS: The reason for the admission and the availability of a day hospital unit had influence in the inadequate hospital admissions in this study.

[Assessment of research methodology on diagnostic laboratory test in Revista Clínica Española and Medicina Clínica].

BASIS: The identification of the methodological limitations of diagnostic research on laboratory tests is the basis in order to guide its enhancement and facilitate the application of the results to the clinical decisions. METHODS: Seventeen articles published in Revista Clínica Española and Medicina Clínica from 1997 to 2000 were analyzed, in which the sensitivity and specificity of a diagnostic laboratory test were determined. Some standardized criteria of methodological quality were independently applied by three investigators. RESULTS: A high frequency in the fulfillment of some key methodological aspects was observed: adequate description of the standard of reference (88%), of the test investigated (88%), of the clinical sample evaluated (71%), and of the prevention of the sequence bias (82%). The assessment of indeterminate results (12%), the test reproducibility (12%), or the description of the origin of the evaluated population (6%) were infrequent. CONCLUSION: The methodological defects of diagnostic laboratory research could be prevented through the collaboration with clinical services and with simple modifications of the trial's designs.

[Tuberculosis and cancer. Experience of a general hospital].

Tuberculosis and cancer are two processes in relationship. The relation between both are studied. We analyzed retrospectively the culture-positive tuberculosis cases in from 1999 to 2002. We described the six cases with tuberculosis and cancer. One hundred and five cases of tuberculosis were observed, 6 cases (5.7%) had cancer. Four cases were pulmonary tuberculosis, one tuberculous pleurisy and other urinary tuberculosis urinary. The two cases with bronchogenic neoplasm had a diagnosis of tuberculosis at same time than cancer. The diagnosis of neoplasm was previous than tuberculosis in two cases (breast neoplasm and hypernephroma), and posterior in others two cases (breast and colon neoplasm). Half of theses patients died. In patients with neoplasm, the possibility of coexist tuberculosis is not depreciable, previous, concomitant or after the diagnosis of neoplasm.

[Diagnostic utility of Osler's nodules in infectious endocarditis among parenteral drug users].

BACKGROUND: The objective of study is to describe of clinic, microbiological and histological data of five cases of infective endocarditis (IE) with Osler's nodes in intravenous drug users. PATIENTS Y METHODS: Prospectively, 43 cases of IE in intravenous drugs users was revised. In 4 patients, a aspirate puncture of Osler's node was performed and in one patient a biopsy of Osler's node was done with Gram's stain and culture of specimen. RESULTS: From 43 episodes of IE, 33 were right-side IE, 9 left-side y 1 right and left side. No patients with right-side IE presented Osler's nodes, however five of 10 (50%) patients with left-side endocarditis. In all of cases gram positive cocci were observed in Gram's strain and Staphylococcus aureus growth on culture of lesion with the same antibiotype than isolated from blood culture. One case a cutaneous biopsy was performed, and inflammatory infiltrate with necrosis was found. CONCLUSIONS: The Gram's strain and culture of specimen aspirated from Osler's nodes were of high utility in the diagnosis of IE in intravenous drugs users. The presence of Osler's nodes in a patient with infective endocarditis must be suggest that the location in left-side. These data suggest that Osler's nodes in infective endocarditis by S. aureus in intravenous drugs users was originated by microvascular septic emboli.

[The Spanish scientific production about human immunodeficiency virus infection/AIDS. A study through MedLine (1991-1999)].

BACKGROUND: To analyze the research output of Spanish authors on human immunodeficiency virus (HIV) infection/AIDS. METHODS: Papers published over 1991-1999 which were recorder in the MedLine database (CD-ROM) were selected by using the key words Spain or Espana in the address of author field and HIV, AIDS, VIH or sida in any field. Papers were analyzed according to publication journal specialty of authors, subjecte matter of the paper, institution, center of origin and geographical distribution. RESULTS: A total of 2,065 papers were studied. Their number doubled, from 148 in 1991 to 295 in 1999 (r = 0.917; p < 0.0001). The number of papers published in foreign journals trebled, from 51 to 182 (r = 0.933; p < 0.001). The journal with the highest number o papers published was Medicina Clínica: 241 (11.7%). Although the main topic was the clinical manifestations of HIV infection (64.6%), the proportion of papers on this subject decreased from 71.4% in 1991-93 to 58.3% in 1997-99 (p < 0.001). On the other hand, the percentage of articles on antiretroviral therapy increased from 3.6% in 1991-93 to 12.4% in 1997-99 (p < 0.001). The greatest number of contributions came from hospitals (79.8% of papers), followed by universities (9.5%). Centers with the highest output were the Hospital Clínic (Barcelona) (5.7%) and the Hospital Carlos III (Madrid) (5.5%). The Autonomous Communities of Madrid (33.1%) and Catalonia (25.3%) concentrated more than half of the total output, followed by Andalusia (11.5%) and the Valencian Community (8.1%). CONCLUSIONS: Spanish output on HIV infection/AIDS research grew during the 1991-1999 period. There was a remarkable increase in the papers published in foreign journals. Moreover, topics changed according to the epidemiological changes observed in HIV infection during the past decade.

[Isolated pulmonary endocarditis on native valve in elderly patient without predisposing factors].

Isolated infective endocarditis in the native pulmonary valve is an unusual clinical entity in patients without predisposing factors and in non-intravenous drugs users. We present the case of a 75-year-old patient, with a subacute clinical picture of fever and pulmonary cavity nodules, admitted to our hospital with an initial suspected diagnosis of pulmonary tuberculosis. The presence of Enterococcal bacteremia in hemocultive and the documentation of a large vegetation in pulmonary valve by transtoracic and transesophageal echocardiography were key factors for final diagnosis.

[Specific mortality rates by DRG and main diagnosis according to CIE-9-MC at a level-II hospital].

INTRODUCTION: The in hospital mortality is a marker of health care quality. It can be evaluated according by the principal diagnosis of disease or by Diagnosis Related Groups (DRG). OBJECTIVES: Know and to analyze the in hospital mortality and mortality rate (MR) in the patients admitted in the Hospital Morales Meseguer (Murcia) of II level of the INSALUD during 1999. METHODOLOGY: Study of the minimum basic group of data into the hospital. RESULTS: The MR was 3.8% of 508 deaths analyzes, 56.7% corresponded a male. The MR was equal in male (3.6%) and females (3.9%). The medium of age into deaths was 77 years. The numbers of deaths inpatients under 80 years was higher in males (n = 197; 65%) than in lower in female (n = 102; 35%)(p = 0.002). The addition of deaths of Internal Medicine and Intensive Care Unit represent a 70% of cases of deaths occurred in the hospital. The MR was higher in Intensive Care Unit (10.5%) followed by Hematology (6.9%) and Internal Medicine (6.1%). Ten DRG represents of 50% of the causes of deaths, and all of them were DRG of medical categories. The DRG more frequents was 541, Respiratory disorders with complication (n = 61, MR 12.8%), followed by DRG 533. Specific cerebrovascular disorders without Transit isquemic accident (n = 33; MR 34.7%), DRG 123 Acute myocardical infarction (AMI) with death (n = 31; MR 100%), DRG 014 Others disorders of nervous system (n = 27; TM: 10.3%) y DRG 552 Disorders of digestive tract without esophagitis, gastroenteritis and not complicated ulcer (n = 27; MR: 31.0). The main diagnostic more frequent was cerebrovascular diseases (n = 60, MR 12.2%), pneumonia-bronchopneumonia (n = 52, MR 10.9%), chronic obstructive lung disease (n = 36, MR 7.1%), AMI (n = 33, MR 11.5%), and neoplasia of digestive tract (n = 26; MR 8.5%). The MR of woman with AMI (19.5%) was higher than man (7.7%) (p = 0.005), the MR in woman with abdominal hernia (4.3%) was higher than man (0.6%) (p = 0.01), and MR of pyelonephritis and urinary infection in man (4.9%) was higher than woman (0%) (p = 0.008). CONCLUSIONS: The mortality and MR by DRG and main diagnostic is an indicator than permit to know and monitoring the quality of health care.

[Infective endocarditis in intravenous drug users. Study of 34 cases].

OBJECTIVE: Infective endocarditis (IE) in injection drug users (IDU) have a special etiologic, epidemiological and clinical characteristics different to IE in the general population. The clinical and evolutive features of a group of IE in IVD are reported. METHODS: A retrospective analysis was made of 34 episodes (24 patients) of IE in IDU in the Catagena Area (Murcia, Sapin). RESULTS: A total 34 episodes, 18 was males (75%) and 6 (25%) females with a age media of 26.1 years (DE, 4.3). Eighty-four percents were infected with human immunodeficiency virus. The location of IE was right-side in 26 (73%), left-side in 7 cases (18%) and right-left in one (2%). Staphylocococcus aureus was isolated in 31 cases (91%), it was meticillin-resistant in 4 cases (13%); Pseudomonas aeruginosa, and Streptococcus equisimilis was isolated in one case each. Fever was present in 33 patients (97%) and more than half were cough, pleuritic chest pain and expectoration. Twenty-five patients with right IE has chest X-ray abnormal, specially nodules-infiltrates pulmonary. Vegetations were not observe in 7 (21%) occasions by transthoracic echocardiography. In six of 8 patients with left-side IE present a cerebri embolisms. Two patients with left IE death (21%). The rate of successful therapy in the right-side IE treated during 2 or 4 weeks were 100%. CONCLUSIONS: The IE in IDU is a entity produced mainly by S. aureus, affect preferentially a right-side cavities and the prognosis is generally good.

[Research on diagnostic tests in Medicina Clinica. A methodological assessment].

BACKGROUND: Research on diagnostic tests have not reached the same methodological rigour as other areas of clinical research. Identification of more frequent and important methodological flaws could contribute to raise the quality of diagnostic test studies. The aim of this study was to evaluate the methodology of diagnostic test studies published in MEDICINA CLINICA. MATERIAL AND METHODS: Forty two articles about diagnostic test studies published in MEDICINA CLINICA from 1992 through 1995 were selected. Two set of methodological criteria were applied (JAMA 1995; 274: 645-651 and Revisiones en Salud Pública 1993; 3: 243-262). Each article was independently evaluated by two observers. RESULTS: Of the 42 articles evaluated, 33 determined sensitivity and specificity, and 9 only sensitivity. There was a well-defined gold-standard in the majority of the studies (90%) but it was not applied to all patients in 21% of them. Description of the diagnostic test evaluated was present in 79% and test reproducibility was assessed in only 19%. Source of patients, eligibility criteria for study subjects and spectrum composition were considered in 31, 36 and 31%, respectively. Avoidance of work-up bias and review bias was done in 69 and 36% of the articles. Only 12% considered indeterminate results, 50% reported test indexes for relevant clinical subgroups and statistical precision was provided in 17% of the studies. CONCLUSION: Methodological quality of the research on diagnostic tests published in MEDICINA CLINICA is similar to that observed in the best world clinical journals. Nevertheless, there are opportunities to improve several aspects of study design and presentation that will facilitate its clinical applicability and general utility.
