Poligrafía domiciliaria en pacientes con patología cardiovascular y sospecha de un SAHS / No disponible

OBJETIVOS: Validar la poligrafía domiciliaria en pacientes con comorbilidad vascular y sospecha de un síndrome de apneas hipopneas del sueño (SAHS) y determinar, en aquellos enfermos con cardiopatía isquémica, si el tratamiento con CPAP influye en el control de esta enfermedad. PACIENTES Y MÉTODOS: Fueron incluidos 42 enfermos (29 hombres y 13 mujeres, edad: 53 ± 7,8 años, IMC: 33 ± 5,2). Se les realizó poligrafía domiciliaria y polisomnografía convencional. Dieciséis pacientes con cardiopatía isquémica fueron evaluados tras el tratamiento con CPAP. El diagnóstico de SAHS se estableció ante un índice de apnea-hipopnea (IAH), en la polisomnografía> 5 y se indicó tratamiento con CPAP si el IAH fue > 15. RESULTADOS: Se observa una correlación y concordancia significativa (p < 0,01) entre la polisomnografía y poligrafía, en el IAH (36 ± 19,9 frente a 32 ± 17,4), r = 0,903 y CCI = 0,938, y en el índice de saturación (33 ± 23,5 frente a 35 ± 22,1), r = 0,896 y CCI = 0,948. Respecto a un IAH > 5 en la polisomnografía, la poligrafía obtiene un área bajo la curva ROC = 1 y para un IAH > 15el área bajo la curva ROC fue de 0,945. Tras el tratamiento con CPAP, los enfermos con cardiopatía isquémica acudieron menos frecuentemente al servicio de urgencias. CONCLUSIONES: La poligrafía domiciliaria es válida para el diagnóstico e indicación de tratamiento. En pacientes con cardiopatía isquémica, la CPAP mejora su control, descendiendo el número de consultas al servicio de urgencias (AU)

OOBJETIVES: To validate home poligraphy in patients with vascular comorbidity and suspicion of obstructive sleep apnea syndrome (OSAS), and to determine in patients with is chemicheart disease if treatment with CPAP influences in their control. PATIENTS AND METHODS: Forty-two patients were included (29 men and 13 women; Age: 53 ± 7.8 years; BMI: 33 ± 5.2)who were made home sleep study and conventional polysomnography. Sixteen patients with ischemic heart disease were evaluate dafter CPAP treatment. Diagnosis of OSAS was stablished when apnea-hypoapnea index (AHI) was > 5 in polysomnography and treatment with CPAP was indicated when AHI > 15. RESULTS: A significative correlation and concordance (p<0.01)were observed between the polysomnography and polygraphy in the AHI (36 ± 19.9 vs 32 ± 17.4), r = 0.903 and CCI = 0.938, and the desaturation index (33 ± 23.5 vs 35 ± 22.1), r = 0.896 and CCI = 0.948.When AHI >5 in polysomnography, the polygraphy obtained an are aunder the ROC curve = 1 and for IAH >15 the area under the ROC curve was 0.945. After CPAP treatment, patients with ischemic heart disease went less frequently to the hospital. CONCLUSIONS: Poligraphy is valid for diagnosis and treatment indication. Patients with ischemic heart disease, CPAP improves their control and reduces visits to the hospital (AU)

Discriminative capacity of calcaneal quantitative ultrasound and of osteoporosis and fracture risk factors in postmenopausal women with osteoporotic fractures.

Bone fragility fractures constitute the principal complication of osteoporosis. The identification of individuals at high risk of sustaining osteoporotic fractures is important for implementing preventive measures. The purpose of this study is to analyze the discriminative capacity of a series of osteoporosis and fracture risk factors, and of calcaneal quantitative ultrasound (QUS), in a population of postmenopausal women with a history of osteoporotic fracture. A cross-sectional analysis was made of a cohort of 5195 women aged 65 or older (mean +/- SD: 72.3 +/- 5.4 years) seen in 58 primary care centers in Spain. A total of 1042 women (20.1%) presented with a history of osteoporotic fracture. Most fractures (93%) were non-vertebral. Age-adjusted odds ratios corresponding to each decrease in one standard deviation of the different QUS parameters ranged from 1.47 to 1.55 (P < 0.001) for fractures. The age-adjusted multivariate analysis yielded the following risk factors independently associated with a history of osteoporotic fracture: number of fertile years, a family history of fracture, falls in the previous year, a history of chronic obstructive airway disease, the use of antiarrhythmic drugs, and a low value for any of the QUS parameters. The area under the receiver operating characteristic curve of the best model was 0.656. In summary, a series of easily assessable osteoporotic fracture risk factors has been identified. QUS was shown to discriminate between women with and without a history of fracture, and constitutes a useful tool for assessing fracture risk. Various of the vertebral and hip fracture risk factors frequently cited in North American and British populations showed no discriminative capacity in our series--thus suggesting that such factors may not be fully applicable to our population and/or to the predominant type of fractures included in the present study.

[The benefits of auditing clinical histories. Our experience over 5 years]. / Interés de las auditorías de historias clínicas. Nuestra experiencia en cinco años.

OBJECTIVE: To evaluate how our clinical records (CR) are filled in and to observe the impact of measures taken to correct faults found over a five-year follow-up period. DESIGN: Three descriptive studies (auditing methodologies) on representative samples of CR selected at random. Four quality indicators were fixed: internal communication (i.e. legibility and comprehensibility), external communication, manageability and the quality of the activity at attendances measured by the SOAP. The optimum standards (OS) were agreed by the team (technique of nominal group). SETTING: "Florida" Health Centre, Alicante. PATIENTS AND OTHERS PARTICIPANTS: Periodic team meetings to analyse results and agree activities. In 1986, N of CR = 367; in 1988, 370; and in 1990, 372. MAIN MEASUREMENTS AND RESULTS: During the follow-up period, the filling-in of all the variables, except the address, the test carried out and blood pressure, improved. But the following did not reach the OS: code, affiliation, origin, instruction, habits, allergies, working activity, socio-economic data, age and gender, family/personal background, test carried out, blood pressure and analytical data. The following all reached the OS: legibility, which went up from 88% to 96.5%, comprehensibility from 62 to 75.3%, external communication from 81 to 88.9%, manageability from 53 to 79.6% and SOAP from 62 to 82.5%. CONCLUSIONS: Auditing allows the level of the filling-in of the CR to be measured. Deficiencies which appear to be due to the design of the record itself can be detected. The efficacy of corrective measures to improve records can also be assessed.
