Abstract
We report the largest study on the prevalence and distribution of HCV genotypes in Spain (2000-2015), and we relate them with clinical, epidemiological and virological factors. Patients from 29 hospitals in 10 autonomous communities (Andalusia, Aragon, Castilla-Leon, Catalonia, Galicia, Canary Islands, Madrid Community, Valencian Community, Murcia Region and Basque Country) have been studied. Annual distribution of HCV genotypes and subtypes, as well as gender, age, transmission route, HIV and/or HBV coinfection, and treatment details were recorded. We included 48595 chronically HCV-infected patients with the following characteristics: median age 51 years (IQR, 44-58), 67.9% male, 19.1% HIV-coinfected, 23.5% HBV-coinfected. Parenteral transmission route was the most frequent (58.7%). Genotype distribution was 66.9% GT1 (24.9% subtype 1a and 37.9% subtype 1b), 2.8% GT2, 17.3% GT3, 11.4% GT4 and 0.1% GT5 and 0.02% GT6. LiPA was the most widely HCV genotyping test used (52.4%). HCV subtype 1a and genotypes 3 and 4 were closely associated with male gender, parenteral route of infection and HIV and HBV coinfection; in contrast, subtype 1b and genotype 2 were associated with female gender, nonparenteral route and mono-infection. Age was related to genotype distribution, and different patterns of distribution and biodiversity index were observed between different geographical areas. Finally, we describe how treatment and changes in transmission routes may have affected HCV genotype prevalence and distribution patterns. We present the most recent data on molecular epidemiology of hepatitis C virus in Spain. This study confirms that genotype distributions vary with age, sex, HIV and HBV coinfection and within geographical areas and epidemiological groups.

Abstract
BACKGROUND To communicate at clinical value of an isolation of Actinomyces radingae from an ulcerated lesion the external supra-malleolus region. MATERIAL AND METHODS We proceed to study the clinical and bacteriological value of an isolated aerobic gram positive rod in pure culture obtained from an ulcerated lesion ocated at the external supra-malleolus region of a 92 years old woman in whom there was later evidence of an epidermoid carcinoma. Surgical and antibiotic treatment were needed. The biochemistry characterization of the isolated was carried out according to the schemes of Weaver-Hollis and Funke et al, as well as the characterization of the fat acids of their cellular wall by gas-liquid chromatography. RESULTS The isolated was identified as Actinomyces radingae. The patient follow-up was satisfactory after the treatment. CONCLUSION The first infection description by Actinomyces radingae is reported wherein its pathological value is evident as it is isolated in pure culture.

Abstract
We report 6 cases of Rett syndrome, a disorder that occurs only in girls and is characterized by slowly progressive deterioration of higher brain function, with dementia and autistic behavior, loss of purposeful use of the hands and deceleration of head growth. We consider interesting this report because Rett syndrome would be an important cause of mental retardation in girls, which has been overlooked until few years ago.

Abstract
Abstract
This rapid, sensitive equilibrium turbidimetric immunoassay for quantification of alpha 1-antitrypsin involves a monospecific antibody, polyethylene glycol 6000 to accelerate and enhance the immunoprecipitation reaction, and Tween 20 surfactant to decrease and stabilize the sample-blank values. Turbidity at 334 nm is measured by an automated discrete analyzer. Grossly lipemic, icteric, or hemolyzed samples can be assayed. Correlation with results by radial immunodiffusion (RID) was excellent (r = 0.97, n = 84). Analytical recovery averaged 97.7 (SD 2.9)%. Within-run CVs ranged from 1.6 to 1.9%, between-day CVs from 2.0 to 3.5%. Reference values for healthy adults (n = 147) were determined by parametric estimation (for an assumed normal distribution of untransformed data). The lower limit (g/L) with its 0.90 confidence interval is 1.23 (range 1.18-1.28), the upper limit is 2.15 (2.10-2.20), and the mean is 1.69 g/L.
