RESUMEN
Objetivo: Determinar la sensibilidad y la precisión de la artrografía mediante resonancia magnética (artro-RM) directa para diagnosticar lesiones intraarticulares asociadas al pinzamiento femoroacetabular. Material y métodos: Estudiamos con artro-RM directa a 51 pacientes con pinzamiento femoroacetabular que se operaron mediante artroscopia de la cadera la cual demostró 37 roturas del labrum, 44 lesiones en la unión condrolabral y 40 lesiones del cartílago articular. Correlacionamos los hallazgos de la artro-RM directa preoperatoria con los de la artroscopia de la cadera y calculamos la sensibilidad, especificidad, valor predictivo positivo, valor predictivo negativo e índice de validez de la artro-RM directa. Resultados: La sensibilidad y la especificidad de la artro-RM directa para diagnosticar la rotura labral fueron del 94,5 y del 100%, para la lesión de la unión condrolabral del 100 y del 87,5%, y para la lesión del cartílago articular del 92,5 y del 54,5%, respectivamente. El valor predictivo negativo de la artro-RM fue del 100% para las lesiones de la unión condrolabral. La artro-RM definió con precisión las lesiones extensas del cartílago y los cambios óseos secundarios, principal factor pronóstico desfavorable, mientras que su rentabilidad diagnóstica fue menor en pequeñas lesiones condrales. Conclusión: La artro-RM directa detecta y caracteriza adecuadamente las lesiones del labrum acetabular, de la unión condrolabral, lesiones extensas del cartílago articular y los cambios óseos secundarios en pacientes con pinzamiento femoroacetabular (AU)
Objective: To determine the sensitivity and accuracy of direct MR arthrography in the diagnosis of intra-articular lesions associated with femoroacetabular impingement. Material and methods: We used direct MR arthrography to study 51 patients with femoroacetabular impingement who underwent arthroscopic hip surgery. Surgery demonstrated 37 labral tears, 44 lesions in the labral-chondral transitional zone, and 40 lesions of the articular cartilage. We correlated the findings at preoperative direct MR arthrography with those of hip arthroscopy and calculated the sensitivity, specificity, positive predictive value, negative predictive value, and validity index for direct MR arthrography. Results: The sensitivity and specificity of MR arthrography were 94.5% and 100%, respectively, for diagnosing labral tears, 100% and 87.5%, respectively, for diagnosing lesions of the labral-chondral transition zone, and 92.5% and 54.5%, respectively, for diagnosing lesions of the articular cartilage. The negative predictive value of MR arthrography for lesions of the labral-chondral transitional zone was 100%. MR arthrography accurately defined extensive lesions of the cartilage and the secondary osseous changes (the main factor in poor prognosis), although its diagnostic performance was not so good in small chondral lesions. Conclusion: In patients with femoroacetabular impingement, direct MR arthrography can adequately detect and characterize lesions of the acetabular labrum and of the labral-chondral transitional zone as well as extensive lesions of the articular cartilage and secondary osseous changes (AU)

ObjetivoDeterminar la fiabilidad y la validez de la Escala de Conductas Indicadoras de Dolor (ESCID) para valorar el dolor en pacientes críticos, no comunicativos y sometidos a ventilación mecánica (VM).MétodosEstudio observacional de desarrollo y validación de una escala como instrumento de medida en pacientes ingresados en UCI mayores de 18 años, con VM, no comunicativos. Se evaluó el dolor con las escalas Behavioural Pain Scale (BPS) y ESCID, simultáneamente, por dos evaluadores independientes, en aplicación de dos procedimientos dolorosos (PD): movilización y aspiración de secreciones, medidos antes, durante y después del PD. Análisis descriptivo de las características generales de la muestra. La fiabilidad de ESCID se midió a través de la consistencia interna de cada ítem con el coeficiente alfa de Cronbach. Mediante análisis de varianza de medidas repetidas se midió concordancia interobservador e intraobservador; se compararon los componentes de las dos escalas de dolor para medir el cambio entre los resultados obtenidos en función del tiempo, observador y procedimiento. La correlación entre las dos escalas se midió con la correlación de Pearson.ResultadosCuatrocientas ochenta observaciones en 42 pacientes, 62% varones; edad 57,33 ±16,35. Predomina patología infecciosa (36%) y neurológica (35%). Glasgow Coma Scale 8,45 ± 1,2 y Richmond Agitation-Sedation Scale −2,55 ± 1,5. La tensión arterial, frecuencia cardiaca y frecuencia respiratoria se mantuvieron estables. El coeficiente alfa de Cronbach para ESCID osciló entre 0,70-0,80. Existe una buena correlación entre ESCID y BPS, en los tres momentos de medición: correlación de Pearson antes 0,97, durante 0,94 y después 0,95.ConclusionesESCID constituye una herramienta útil y válida para valorar el dolor en pacientes críticos, no comunicativos y sometidos a VM (AU)

Introducción. Este estudio se propone evaluar el pronóstico de las infecciones del tracto urinario (ITU) tratadas empíricamente con tratamiento antibiótico inadecuado. Material y método. Estudio de cohortes prospectivo, de pacientes mayores de 18 años de edad, atendidos en un servicio de urgencias hospitalario entre el 01/02 y el 31/05 de 2007 por síntomas miccionales, acompañados de piuria (>10leucocitos/mm3 de orina no centrifugada) o tira reactiva positiva para nitritos-leucocitos y urocultivo con >103 unidades formadoras de colonias. Se consideró que el tratamiento antibiótico prescrito empíricamente era adecuado si la bacteria aislada era sensible y se había prescrito por un tiempo correcto. Se consideró que hubo fracaso terapéutico cuando persistía la sintomatología tras 5 días de tratamiento. Se registraron la edad, el sexo, la presencia de sonda vesical permanente, el tipo de ITU, hospitalización en los 3 meses previos, la procedencia del paciente y las enfermedades asociadas. Resultados. Se aislaron 177 bacterias en 168 pacientes. En 29 casos (17,3%) el microorganismo aislado era resistente al antibiótico prescrito. En tan solo 6 pacientes hubo fracaso terapéutico, aunque no precisaron ingreso hospitalario. Los pacientes que vivían en una residencia de ancianos (13,7 vs 2,2%, p=0,015) o que habían sido ingresados durante los 3 meses previos (20,6 vs 4,3%, p=0,039) presentaron un mayor riesgo de recibir tratamiento inadecuado. Conclusiones. El pronóstico de los pacientes atendidos en Servicios de Urgencias Hospitalarios por ITU con tratamiento antibiótico discordante es favorable en la mayoría de los casos. Sería recomendable la realización de urocultivo en pacientes con mayor riesgo de padecer ITU por un microorganismo resistente(AU)
Introduction. This study aims to evaluate the prognosis of urinary tract infections (UTI) treated empirically with inadequate antibiotic treatment. Material and Methods. Prospective cohort study of patients over 18 years of age, attended in the hospital emergency service between 01/02 and 31/05 of 2007, due to micturation symptoms, accompanied by pyuria (>10leukocytes/mm3 of uncentrifuged urine) or positive reactive strip for nitrites-leukocytes and urine culture with >103 colony forming units. It was considered that the antibiotic treatment prescribed empirically was adequate if the bacteria isolated was sensitive and had been prescribed for the correct time. It was considered that there was therapeutic failure when the symptoms persisted after 5 days of treatment. Age, gender, presence of indwelling bladder catheter, type of UTI, hospitalization in the previous 3 months, origin of the patient and associated diseases were recorded. Results. A total of 177 bacteria were isolated in 168 patients. In 29 cases (17.3%), the microorganism isolated was resistant to the antibiotic prescribed. There was thereaputic failure in only 6 patients, although they did not required hospital admission. The patients who lived in a residential home for the elderly (13.7% vs 2.2%, P=0.015) or who had been hospitalized during the previous 3 months (20.6% vs 4.3%, p=0.039) had a greater risk of receiving inadequate treatment. Conclusions. The prognosis of the patients attended in the emergency hospital service due to UTI with discordant antibiotic treatment is favorable in most of the cases. Performing urine culture in patients with greater risk of suffering UTI due to a resistant microorganism would be recommendable(AU)

INTRODUCTION: The Hoffmann reflex or H reflex is an electrical counterpart of the myotatic reflex. In normal adults is elicited with stimulating the tibial and the median nerves. It is useful as an adjunct study of neuroexamination and assesses the corresponding arc reflexes in their integrity. SUBJECTS AND METHODS: 248 H reflexes were studied stimulating the tibial nerve in 124 healthy subjects. RESULTS: The latency values were: minimum 23.6 ms; maximum 29.8 ms; mean value 27.6 ± 1.41 ms. CONCLUSION: This work explains the technique to obtain the H reflex and discusses the need for normalized values for each neurophysiology lab.

Objetivo: Analizar los resultados obtenidos en cinco años deConsulta de Tabaquismo, valorando la abstinencia tabáquica al año de seguimiento de los fumadores que acudieron en fase de acción. Pacientes y métodos: Los fumadores proceden del Hospital Puerta de Hierro (trabajadores y pacientes) y del área sanitaria VI de Madrid. La consulta es individualizada y la metodología se ha ajustado a las recomendaciones del área de tabaquismo de la SEPAR, basadas en el tratamiento combinado de terapia farmacológica y apoyo psicológico verbal y reforzado con una guía práctica para dejar de fumar. La abstinencia anual se ha valorado en porcentajes absolutos y por el método de probabilidades de Kaplan-Meier, primero en todos los fumadores conjuntamente y segundo, en relación con la presencia o ausencia de: enfermedades relacionadas con el tabaquismo, diabetes y depresión. En este caso también se calculó el riesgo relativo de recaída (RR) y el intervalo de confianza del 95% (IC.95%). Se ha valorado en hombres y mujeres la ganancia de peso a los seis meses y al año de abstinencia. Resultados: El seguimiento se ha realizado en los 226 fumadores en fase de acción (46 % hombres, 54 % mujeres). Los tratamientos más utilizados fueron la terapia sustitutiva con nicotina (67%) y el bupropión (13%). Dejan de fumar un año el 31% (28,6% hombres y 32,2% mujeres). El 37% están abstinentes seis meses, el 48% tres meses, y el 72% un mes. La probabilidad de abstinencia por Kaplan-Meier es de 32%. El tratamiento que mejores resultados mostró fue la terapia sustitutiva con nicotina, tanto en forma de parches como asociada a chicles (35% de abstinencia anual). Los fumadores que tenían alguna patología asociada al tabaquismo eran 97. Su edad media, años de fumador e intentos previos de abandono eran significativamente mayores (*p<0,005) que de los 129 fumadores sin patología asociada. De los primeros dejan de fumar un año el 21% (probabilidad de abstinencia 23%) mientras que los que no tienen patología asociada dejan de fumar el 38% (probabilidad de abstinencia 38%). El riesgo de recaída es 1,6 veces superior en el grupo con patología asociada. Conclusiones: Nuestra consulta de tabaquismo consigue unas tasas de abandono de casi un tercio, que es bastante menor en los fumadores que tienen una patología asociada al tabaco. Estas tasas refuerzan la justificación de las consultas de tabaquismo como instrumento para facilitar la deshabituación tabáquica (AU)
Objective: Analyze the results obtained in 5 years of Smoking CessationConsultation, evaluating abstinence at 1 year of follow-up of the smokers who came in the action phase. Patients and methods: Those smokers who came from the hospital Puerta de Hierro (workers and patients) and from the health-care area VI of Madrid were included. The consultation was individualized and the method was adjusted to the SEPAR recommendations of the smoking cessation area, based on combined treatment of drug therapy and all psychological support and reinforced with a practical guide to quit smoking. Yearly abstinence was evaluated in absolute percentages and with the Kaplan-Meier likelihood method, first in all of the smokers jointly and then in relationship with the presence or absence of: diseases related with smoking, diabetes and depression. In this case, the relative risk of relapse (RR) and 95% confidence interval (95% CI) were also calculated. Weight gain at 6 months and 1 year of abstinence was also evaluated in men and women. Results: The follow-up was made in 226 smokers in the action phase(46% in men,54% women). The treatments used most were nicotine replacement therapy (67%) and Bupropion (13%). After 1 year, 31% (28.6% in men and 32.2% women) quit smoking. At 6 months, 37% were abstinent, at 3 months 48% and at 1 month 72%. The Kaplan Meier likelihood of abstinence is 32%. The treatment that had the best results was nicotine replacement therapy, both with patches and gum (35% of annual abstinence). There were 97 smokers who had a disease associated to smoking. Their main age, years of smoking and previous attempts to quit were significantly greater (*p < 0,005) then those of the 129 smokers with no associated disease. In the first group 21% quit smoking at 1 year (abstinence likelihood 23%) while 38% of those who had no associated disease quit smoking (abstinence likelihood 38%). Risk of relapse was 1.6 times greater in the group with associated disease. Conclusions: Our tobacco cessation clinic achieves cessation rates of almost one third, which is much less in the smokers who have any disease associated to tobacco. These rates reinforce the justification of smoking cessation consultation as an instrument to facilitate smoking cessation (AU)

BACKGROUND: Malnutrition is a frequent clinical finding in elderly inpatients that is deleterious to the physiologic function of several body's organs or systems that is accompanied of an increase of the length of hospitalization, economic burden and mortality. Protein-energy malnutrition risk factors in elderly patients are not well defined. METHOD: A transversal study of inpatients over 70 years in a internal medicine ward was undertaken in order to know the protein-energy malnutrition's prevalence a possible risk factors. It was considered that a patient suffered from had protein-energy malnutrition if he or she had a tricipital skinfold thickness or an arm circumference under 10th percentile and/or had low levels of two of the following clinical parameters: plasmatic albumin (under 3.5 mg/100 ml). Plasmatic transferrin (under 150 mg/100 ml) or a lymphocytic cell count (under 1,500 cells/ml). RESULTS: A hundred and five patients were included. Mean age was 83.0 +/- 6.4 years with a predominance of the female sex (61%). Thirty-three patients (31%) were sent from nursing homes. A 35% were very dependent and frail elderly patients. Fifty-eight patients presented at hospital with protein-energy malnutrition (prevalence = 57.1%; CI 95% 47.1%-66.8%). Chronic obstructive pulmonary disease (COPD) and a acute infectious disease were independent risk factors associated protein-energy malnutrition (prevalence ratio of 1.4 and 0.5, respectively). CONCLUSIONS: Protein-energy malnutrition's prevalence in elderly inpatients is very important. Infectious diseases and COPD are positively and negatively associated with protein-energy malnutrition.

Fundamento: La malnutrición en ancianos que son ingresados en los hospitales es un hecho frecuente y ocasiona un deterioro en distintos órganos y sistemas que condiciona un aumento de la estancia hospitalaria, costes sanitarios y mortalidad. Los factores de riesgo de malnutrición en este grupo de enfermos no están bien estudiados. Método: Se realizó un estudio transversal de pacientes mayores de 70 años que ingresaron en una sala de hospitalización de medicina interna para conocer la prevalencia de malnutrición al ingreso y sus posibles factores de riesgo. Se consideró que un paciente padecía malnutrición si el pliegue tricipital o el perímetro braquial se situaba por debajo del percentil 10 y/o presentaba valores inferiores a la normalidad en al menos dos de los siguientes parámetros: albúmina plasmática (menor de 3,5 mg/dl), transferrina plasmática (menor de 150 mg/dl) o recuento linfocitario en sangre periférica (menor de 1500/mm3). Resultados: El promedio de edad de los 105 pacientes incluidos en el estudio fue de 83,0 ± 6,4 años, con un predominio de pacientes del sexo femenino (61 por ciento). Treinta y tres pacientes (31 por ciento) procedían de residencias de ancianos. Un 35 por ciento que presentaban un deterioro grave del estado funcional. Cincuenta y ocho pacientes presentaron malnutrición en el momento del ingreso (prevalencia = 57,1 por ciento; IC95 por ciento 47,1 - 66,8 por ciento). Los únicos factores asociados a malnutrición al ingreso fueron presentar una enfermedad infecciosa y padecer enfermedad pulomonar obstructiva crónica (EPOC, razones de prevalencia 1,4 y 0,5 respectivamente). Conclusiones: La prevalencia de malnutrición en los ancianos hospitalizados de más de 70 años es muy elevada. Las enfermedades infecciosas en el momento del ingreso y la EPOC se asocian positiva y negativamente al riesgo de presentar malnutrición (AU)

INTRODUCTION: A computer-driven unit-dose drug-dispensing system allows for improved knowledge on pharmaceutical costs per DRG and clinical department, between-hospital pharmacoeconomic studies to be carried out, as well as deviation analysis. METHODS: A retrospective, cost-minimization study was undertaken to both analyze and compare prescriptions for a number of antibiotics and bronchodilators, and their costs in both 89 and 90 DRGs, as well as their cost per hospital stay in patients admitted to the Internal Medicine Departments of two hospitals in Areas 6 (HUPH) and 9 (SVO) in CAM (Autonomous Community of Madrid). A statistical analysis was performed using the Kolmogorov-Smirnov test, Student 's "t" test, Mann-Whitney test, and least squares method. RESULTS AND CONCLUSIONS: Patient samples are similar, with no significant differences existing in clinical status at admission or in cure percentage. Also, no significant differences exist in antibiotic use, except for clarithromycin and ceftriaxone, which were more commonly used at SVO (P = 0.001 and P = 0.003, respectively), and levofloxacin, which was more commonly prescribed at HUPH (P < 0.001). For identical results measured by using the cure index and mean stay, the cost of antibiotic therapy was significantly higher at HUPH (113.57 euro) versus SVO (78.32 euro), which related to a wider use of levofloxacin; while no statistical relation to clinical status was found that warranted its choice. No differences were seen in bronchoinhaler use which, together with antibiotics, represent 82.6% of cost at HUPH and 72% at SVO.

BACKGROUND: Community-acquired pneumonia (CAP) frequently determines inpatient treatment and has a high mortality. It is desirable to know which factors predicts a favorable outcome of elderly patients with CAP. This fact could allow that a growing number of patients could be treated in their home. OBJECTIVE: To investigate the variables related with the survival of hospitalized elderly patients for with CAP. METHODS: We carried out a retrospective study of 158 patients aged more than 65 years, that were admitted to our hospital for CAP. RESULTS: Mean age was 80.3 +/- 8.2 years (66-98 years). Eighty nine (56%) patients were men and 69 (44%) were women. Twenty seven patients (17%) died during their stay in the hospital. By multivariate analysis, independent variables associated with survival were: confusion (p = 0.0001), treatment with H2 receptor antagonists (p = 0.01), respiratory frequency (above 30 per minute, p = 0.01) and arterial pH (below 7.40, p = 0.03). Sensibility and specificity about prediction of survival in elderly patients with PAC who hadn't any variables above pointed out were 0.89 and 0.64, respectively. CONCLUSIONS: Application of this results could help physicians make decisions about hospitalization for elderly patients with PAC.

Cox regression analysis was used in the study of 151 cases of surgically treated colorrectal carcinoma. A "curative" resection was performed in all of them. Clinical data from medical records, histology, biochemical determinations, and intraoperative findings were assessed. Four of the studied variables were significantly related to tumor recurrence: Dukes stage, tumor spread, histological variety and preoperative CEA level. Age, sex, tumor location, surgical technique, lymphocytes in the peripheral blood, preoperative levels of acute phase reactants and hepatic enzymes did not provide information about the final outcome of these patients.

A method is devised for the automatic computation of data obtained from a series of determinations by radioimmunoassay or by competitive protein binding. The input data is introduced by means of an automatic paper tape punch attached to the sample counter. A series of programs is set up for a Hewlett Packard computer, model 2116B with 16K, which calculates bound and free fractions with control processes for varying possible errors. From experimental data, by linear least squares regression, a standard curve of best fit is derived and is considered in three different ways. The curve of best fit is selected by comparing the correlation coefficients obtained and by calculating the unknown sample concentrations. The program presents the results graphically together with a list of results which is for use within the Radiochemistry laboratory. Individual reports are also prepared for sending to those departments that requested the test.
