Role of an intermittent claudication questionnaire for the diagnosis of PAD in ambulatory patients with type 2 diabetes.

AIM: In epidemiological studies, peripheral arterial disease is assessed by the measurement of the ankle/brachial index (ABI), thus enabling detection of asymptomatic disease. Our aim was to evaluate the diagnostic accuracy of a validated questionnaire on intermittent claudication for peripheral arterial disease in a clinical setting. METHODS: We administered the Edinburgh questionnaire on intermittent claudication and measured ABI using a portable Doppler in 456 outpatients with type 2 diabetes. Subjects with intermittent claudication and an ABI above 0.9 were examined with color Doppler ultrasound imaging. Peripheral arterial disease was considered to be present when the ABI was <0.9 or the color Doppler arterial waveform was monophasic. RESULTS: Thirty-five (7.6%) of the 456 patients had intermittent claudication. Of these, 22 (63%) had an ABI <0.9 and the remaining 13 (37%) had an ABI >0.9. Of these latter, 12 were reexamined and 3 (25%) were found to have monophasic waveforms in color Doppler, thus being diagnosed with peripheral arterial disease. The overall accuracy of intermittent claudication for peripheral arterial disease was 75% (95% CI, 71-79). CONCLUSION: Among patients with type 2 diabetes, a normal ABI does not rule out peripheral arterial disease; the use of an intermittent claudication questionnaire is able to identify correctly the disease in 3 out of 4 patients with diabetes. Our results suggest incorporating the intermittent claudication questionnaire into the general consultation instead of the general screening of the ABI.

A case-control study suggests that the CCR6 locus is not involved in the susceptibility to giant cell arteritis.

OBJECTIVES: Polymorphisms of the CC chemokine receptor 6 (CCR6) gene have been recently reported to be associated with a number of autoimmune diseases. We aimed to investigate the possible influence of CCR6 rs3093024 gene variant in the susceptibility to and clinical expression of GCA. METHODS: The CCR6 polymorphism rs3093024 was genotyped in a total of 463 Spanish patients diagnosed with biopsy-proven GCA and 920 healthy controls using a TaqMan® allelic discrimination assay. PLINK software was used for the statistical analyses. RESULTS: No significant association between this CCR6 variant and GCA was observed (p=0.42, OR=0.94, CI95% 0.79-1.10). Similarly, when patients were stratified according to the specific clinical features of GCA such as polymyalgia rheumatica, visual ischaemic manifestations or irreversible occlusive disease, no statistical significant difference was detected either between the case subgroups and the control set or between GCA patients with and without the specific features of the disease. CONCLUSIONS: Our results suggest that the CCR6 rs3093024 polymorphism may not play a relevant role in the GCA pathophysiology.

A multicentric STIMG (Soft Tissue Infections Malacitan Group) study results]. / Características clínicas, epidemiológicas y factores asociados a mortalidad en los pacientes hospitalizados por infecciones de piel y partes blandas. Resultados del estudio multicéntrico STIMG.

OBJECTIVES: To describe the characteristics of patients admitted in hospitals with soft tissue infections, and analyse the variables whose died, in order to define risk groups. METHOD: retrospective analysis of medical reports of all patient admitted during 2002 year for soft tissue infections in public malacitans hospitals. We excluded the patient with soft tissue infections associated with burns, surgery, pressure ulcers, and orbit cellulitis. We analysed clinical, biochemical variables and indications for yields and imaging tests, so the empiric antibiotic treatment established and its correlations with practice guidelines. RESULTS: We analysed 391 admissions of 374 patients. Cellulitis was the most frequent diagnosis (69.3%). We did imaging tests in 51.6%. In 94.3% of cases were treated with empirics antibiotics. The most prescribed drug was amoxiciline plus clavulanate (39%). 27 patients died, 40.7% of them for septic cause. All deceased patients had chronic diseases. The only biochemical parameters associated with mortality were serum proteins and albumina (55 +/- 9 g/L vs. 63 +/- 8 g/L; p = 0.0231) and (22 +/- 7 g/L vs. 29 +/- 7 g/L; p = 0.0125) respectively. CONCLUSIONS: Cellullitis are the most frequent soft tissue infections that requires admissions in hospitals. We overuse imaging test and don t follow the practice guidelines recommendations in antibiotic therapy. Primary soft issue infection s mortality is low and it s restricted to people with chronic illness, deep infections and bad nutritional status.

Objetivos: Describir las características de los pacientes hospitalizados con infecciones de piel y partes blandas (IPPB) y analizar las variables de los que fallecen durante el ingreso para definir grupos de riesgo. Metodo: Análisis retrospectivo de las historias clínicas de todos los pacientes que fueron dados de alta con IPPB durante el año 2002, en los hospitales públicos de la provincia de Málaga. Se excluyen infecciones secundarias a pie diabético, cirugía, quemados, úlceras por decúbito y la celulitis orbitaria. Se analizaron variables clínicas, bioquímicas, indicación y validez diagnóstica de pruebas microbiológicas y de imagen, así como el tratamiento antibiótico empírico iniciado y su correlación con las recomendaciones terapéuticas establecidas. Resultados: Analizamos 391 ingresos de 374 pacientes. La celulitis fue el diagnóstico más frecuente (69,3%). Se realizaron pruebas de imagen en el 51,6% de los casos. El antibiótico más empleado fue la amoxicilina con ácido clavulánico (39%). Fallecieron 27 (6,7%), el 40,7% por el proceso séptico en sí. Todos los fallecidos, tenían algún tipo de enfermedad crónica asociada. Las únicas variables analíticas que se asociaron de forma significativa a mayor mortalidad fueron las proteínas totales (55 ± 9 g/L vs. 63 ± 8 g/L; p = 0,0231) y los concentraciones séricas de albúmina (22 ± 7 g/L vs. 29 ± 7 g/L; p = 0,0125). Conclusiones: Las celulitis es la IPPB que mayor número de ingresos genera en nuestro medio. Apreciamos una sobreutilización de pruebas de imagen y una desviación sobre las recomendaciones terapéuticas y el tratamiento aplicado en nuestros hospitales. La mortalidad global observada es baja y afecta de manera exclusiva a pacientes con mal estado nutricional al ingreso, enfermedades crónicas o infecciones profundas
