Background and Objective: White coat effect (WCE) is one of the main bias that can affect office blood pressure (BP) measurement. Therefore, it is a factor must be considered in hypertensives to avoid mistakes in diagnosis and/or treatment. Employment of automated office BP (AOBP) devices could diminish that effect., Methods: Two studies were designed with the objective of evaluating differences between routinely office and AOBP measurements. WCE was also assessed. First, the TRUE-ESP study included normotensive and hypertensive patients attending specialized consultations at Cardiology, Nephrology, Internal Medicine, Endocrinology and Family Practice. Second, the TRUE-HTA study included hypertensives attending a protocoled Hypertension Unit, with a trained staff., Results: TRUE-ESP study included 300 patients, 76% being hypertensives. A significant difference between office BP and AOBP measurement (SBP/DBP 9.8±11.6/3.4±7.9 mmHg, P<.001) was observed. Percentage of patients gathering WCE criteria was 27.7%. TRUE-HTA study included 101 hypertensive patients. A significant difference between office BP and AOBP measurement (SBP/DBP 5.7±9.3/2.1±5.3 mmHg, P<.001) and activity period-ABPM (SBP/DBP 8.5±6.7/3.5±2.5 mmHg, P<.001) was observed. Percentage of WCE patients was 32.1%., Conclusions: Use of AOBP devices can contribute to decrease WCE and to improve accuracy of office BP measurement., (Copyright © 2011 Elsevier España, S.L.

Joint manifestation in Lyme disease hare shown similarities to those in reactive arthritis. SAPHO syndrome can also be included into the group of seronegative spondyloarthrophaties. It is presented a patient with joint, ocular and serological features proper of Lyme disease and after ones suggestive of SAPHO syndrome, who responds properly to an antibiotic treatment. It is considered the possibility that some patients suffering from SAPHO syndrome can also be suffering from Lyme disease.

Background: The discovery of the hepatitis C virus (HCV) and the possibility of determining anti-HCV serum antibodies has permitted greater etiological, clinical and epidemiological knowledge of non A non B hepatitis (NANB)., Methods: The clinical and epidemiological characteristics of 47 patients with acute hepatitis C were studied. Diagnosis was based on compatible clinical and analytical picture as well as positivity of the anti-HCV antibodies., Results: Thirty-eight percent of the patients were intravenous drug abusers (IVDA). Thirty-four percent had transfusion antecedents and the remaining were sporadic forms of which 3 cases corresponded to health care workers. The study of other viral markers demonstrated that only in the IVDA collective did infections by hepatitis B and delta (HBV and HDV) and by the human immunodeficiency virus (HIV) coexist. Anti-HCV antibodies were detected between 15 days and 8 months (mean 38 +/- 74 days) of clinic initiation; with no differences being found regarding the form of contagion. The incubation period of transfused patients was 50 +/- 15 days. In 2 cases the disease followed a biphasic course, in 4 patients a cholestatic profile was observed, and in 12 the hepatitis was anicteric. In 28% of the cases controlled over 6 months the disease autolimited itself and 72% developed active chronic hepatitis., Conclusions: Most cases of acute hepatitis C are of intravenous origin with a prolonged period of anti-HCV positivization. No differences exist in the clinical picture of the disease regarding the form of contagion and the great tendency to chronicity of hepatitis C is confirmed, regardless of the mechanisms of acquiring the disease.
