Abstract
Abstract. Twitter is a service that enables users to post messages ("tweets") of up to 140 characters supporting a variety of communicative practices. In this paper we analyze different aspects related to the use of Twitter in different National Meteorological Services (NMS) worldwide. Firstly, we will review the general position of NMS worldwide regarding the use of Twitter technology. Secondly, we will focus on different practices of some selected meteorological services. Thirdly, we will deal specifically with the Basque Meteorology Agency (Euskalmet) case. Finally some conclusions are presented.

Abstract
Tinea cruris is a dermatophytosis that mainly affects males. Infections in females are rare, and there are no known data on the frequency of tinea cruris in female prostitutes. We describe seven female prostitutes with tinea cruris with on age range of between 19-34 years (mean 25.3). Each prostitute had a mean of 50 sexual partners per month. Four Trichophyton mentagrophytes (57.1%), 2 T rubrum (28.6%), and 1 Epidermophyton floccosum (14.3%) isolates were cultered. Tinea cruris transmission is mainly indirect, but direct contact may serve to transmit the disease in some cases, and the spread of active lesions in prostitutes through multiple contacts among with their clients is possible.

Abstract
To establish the best method for boric acid susceptibility testing, we compared two agar dilution methods (high and low inoculum) and a standard broth microdilution method (from the National Commitee for Clinical Laboratory Standards document NCCLS M-27A). Saccharomyces cerevisiae (37) and non-C. albicans Candida (39) isolates, as well as one isolate of Trichosporon sp., were included. All were isolated from female workers with vulvovaginitis. Good agreement within a fourfold dilution range was found between the three methods, and only the broth microdilution method versus the agar dilution method with high inoculum showed significant discrepancies. Reading results was easier with the broth microdilution method than with the agar dilution methods because of partial growth inhibition in the latter. In conclusion, broth microdilution is a suitable method for testing yeast susceptibility to boric acid.

Abstract
Genital human papillomavirus (HPV) infection is sexually transmitted. The aim of the study was to characterize serological responses to HPV types 16, 18, 31, and 58 by exploring type-specific virus-like particles (VLPs) in two groups of women with very distinct sexual behaviors. Anti-VLP antibodies for types 16, 18, 31, and 58 and HPV DNA in cervical cells were investigated with 177 prostitutes and 283 age-matched controls from the female general population in Spain. Anti-VLP positivity increased with number of lifetime sexual partners in women from the general population, and no seroresponse was found in virgins. However, in prostitutes HPV infection was characterized by higher multireactivity to three or four VLPs (25%) than the general population (3%) and by a more frequent antibody response to HPV-58 than in the general population. About 75% of the women seropositive for type 58 had been born in a Latin American country. Seroprevalence of HPV and cervical HPV DNA in prostitutes were 14 and 10 times higher than observed in women in the general population (prevalence odds ratio [POR] of HPV seropositivity, 14.04 [95%; CI = 8.4 to 23.6] and POR for HPV DNA, 10.4 [95% CI = 3.9 to 27.6). Our results indicate that prostitutes are at an increased risk of oncogenic HPV infections, and they confirm the validity of anti-VLPs as markers of present or past HPV infection, that the number of sexual partners is the major determinant in acquisition of oncogenic HPV, and that anti-VLPs could be used as a marker of repeated infection in prostitutes.

Abstract
The aim of this study was to determine the antifungal susceptibility of 108 Candida albicans and 23 Candida glabrata isolates obtained from female prostitutes with vulvovaginitis, a population for which available data is limited. Amphotericin B, flucytosine, and fluconazole were tested by broth microdilution, and boric acid was tested by the agar dilution method. The susceptibility patterns found in this population were the same as those in the general population. Candida glabrata required greater concentrations of boric acid for inhibition in vitro than did Candida albicans.

Abstract
Vulvovaginal candidiasis is a frequent inflammatory process in women but it has not been widely studied in female sex workers (FSWs). To estimate the frequency of Candida species infection in FSWs and to identify related risk factors and clinical findings, we carried out a retrospective study of 1923 FSWs over 11 years. We also performed a prospective study of 163 consecutive FSWs with a history of candidiasis during a 4-year period. Candida species were isolated in 1967 samples (18.5% of the total). Candida albicans (89.3%) was the most frequent species, followed by Candida glabrata (2.7%), Candida parapsilosis (1.2%) and Saccharomyces cerevisiae (0.4%). In the prospective study of 163 patients, we found vaginal discharge in 76.1% of cases, soreness in 52.1% and vulval pruritus in 32.5%. We identified 12 patients (7.4%) with recurrent vulvovaginal candidiasis. No statistical difference was found between recurrent vulvovaginitis and the use of oral contraceptives, oral sex, tight-fitting clothing and synthetic underwear. FSWs have the same prevalence of candidiasis as other groups of women described in published literature. The proportion of albicans and non-albicans species does not differ between women with recurrent and non-recurrent vulvovaginal candidiasis (VVC).

Abstract
OBJECTIVE To describe two patients with scrotal granuloma due to silicone oil migrated from the hip. METHODS/RESULTS Two male transsexuals without genitoplasty developed scrotal inflammatory masses after subcutaneous injection of silicone oil to remodel the hip contour. Imaging studies and pathologic examination disclosed lesions similar to those encountered in ruptured silicone breast implants. CONCLUSIONS Silicone migration to the scrotum through subdermal fascial planes can cause a granulomatous lesion similar to that of ruptured breast implants. The migratory pathway is similar to that of scrotal emphysema and, inversely, the dissemination of necrotizing fasciitis of the genitalia.

Abstract
BACKGROUND Haemophilus spp. had been previously suggested as a potential pathogen in genitourinary infections that could be sexually transmitted. In order to check that suggestions we have determined the incidence, pathogenic role, possible sexual transmission and susceptibility to antibiotics in isolates of Haemophilus parainfluenzae and Haemophilus influenzae from genital tract infections. The microbiological samples were taken during a period of four years from patients attended in a Service of Sexual Transmission Diseases and the data were further reviewed. METHODS The study included 5,572 genital specimens from 2,182 women prostitutes with different genitourinary infections and from 825 men with urethritis. Microbiological samples were cultured in a non-specific media for genital pathogens and species of Haemophilus spp. and clinical circumstances of isolation were evaluated. Susceptibility tests were performed by using a standard microdilution test. RESULTS Haemophilus spp. was isolated in 155 samples (2.8%) using a non-selective culture method. H. parainfluenzae was isolated in 100 cases (64.5%), Haemophilus influenzae in 45 cases (29%) and Haemophilus spp. in 10 strains (6.4%). Haemophilus spp. was isolated as a sole pathogen in men with urethritis (8 cases), epididymo-orchitis (2 cases), cervicitis and/or vaginitis (9 cases) and Bartholin's Abscess (2 cases). The most frequent biotypes were H. parainfluenzae biotype II (43%) and III (19%), and H. influenzae biotype IV (35.5%). Beta lactamase activity and ampicillin resistance were present in 29% of the H. parainfluenzae strains and in the 26.7% of clinical isolates of H. influenzae. CONCLUSIONS 1) Haemophilus spp. was isolated from genitourinary infections at a low frequency in the studied group. 2) The pathogenic role of Haemophilus spp. was suggested when was isolated as a sole pathogen present from some infections of the genitourinary tract such as urethritis in men and Bartholin's abscess in women. 3) The susceptibility to antibiotics in the clinical isolates of Haemophilus spp. from genitourinary infections was similar previously reported studies performed in Spain.

Abstract
BACKGROUND To compare and evaluate two commercial methods for Mycoplasma hominis and Ureaplasma urealyticum with the isolation in agar A7 medium. METHOD One hundred and twenty three vaginal and cervical swabs in women prostitutes, and urethral swabs in men, were studied for Mycoplasma hominis and Ureaplasma urealyticum isolation in agar A7 medium (BioMérieux; France), Mycoplasma IST (BioMérieux, France) and MycoFast ALL-IN (Unipath, U.K.). RESULTS Of all 123 samples studied, it was isolated 24 Mycoplasma hominis (19.5%) and 56 Ureaplasma urealyticum (45.5%) in agar A7. The sensitivity was 100% for Mycoplasma hominis and Ureaplasma urealyticum in Mycoplasma IST versus 29.2% and 50% in MycoFast ALL-IN, both respectively. Specificity was lower for Ureaplasma urealyticum (59.7%) in Mycoplasma IST than in MycoFast ALL-IN (100%). It was found a tetracycline resistance of 15% and 12.5% for Ureaplasma urealyticum and Mycoplasma hominis, both respectively. CONCLUSIONS The use of commercial methods permits to count the genital mycoplasmas, being Mycoplasma IST better than MycoFast ALL-IN for Mycoplasma hominis isolation. Both methods have limitations for Ureaplasma urealyticum and they require the use of agar A7. Mycoplasma IST could be a good method to survey tetracycline resistance.

Abstract
Seven different phenotyping methods for strain differentiation of Candida albicans (auxonotyping, enzymotyping, resistotyping, Phongpaichit's morphotyping, Hunter's morphotyping and Odds and Abbott's biotyping method-1980 and 1983 versions) were compared on a single population of 94 strains. 77.6% of the strains belonged to auxonotyping 1, 59.6% to enzymotyping A, 34% to resistotyping B and 30.8% to BC, 40.4% to Phongpaichit's morphotyping 000,000 and 40.4% to Hunter's morphotyping 'No fringe/Smooth surface'. Using biotyping systems (1980 and 1983 versions), the most frequent biotypes were 145 (29.8%) and 147 (31.9%) respectively. The Discriminatory Index of Hunter and Gaston was employed to carry out comparisons among the different systems. The best discriminatory results, although far from ideal, were found using Phongpaichit's morphotyping (DI = 0.827) and Odds and Abbott's method (DI = 0.815 and 0.831--1980 and 1983 versions). A good discriminatory result was also found using Hunter's morphotyping method together with the biotyping of Odds and Abbott (1983 version). These approximated the ideal (DI = 0.950) and showed minimal difficulty in interpretation. The proposed combined method revealed high discrimination among the vulvovaginal strains, and suggested the absence of transmissible pathogenic strains.

Abstract
The prevalence of cervical intraepithelial neoplasia (CIN) and the association of CIN with prostitution was examined in Oviedo, a region in Spain with low incidence of cervical cancer, and in Cali, Colombia, where the incidence of cervical cancer is 6-10 times higher. In Oviedo, the study included 758 prostitutes attending a sexually transmitted diseases clinic and 1203 nonprostitutes attending a family-planning clinic. In Cali, 775 prostitutes and 1795 nonprostitutes attending health centers were included. Seropositivity to common sexually transmitted agents was investigated in Spanish prostitutes. No significant difference was found in the prevalence of CIN between Oviedo and Cali in both prostitutes (2.5 versus 1.8%) and nonprostitutes (1.2 versus 1.1%). Prostitutes had a 2-fold increased risk of CIN as compared to nonprostitutes; in Spain, the prevalence odds ratio (POR) was 2.3 and the 95% confidence interval (CI) was 1.1-4.5, and, in Colombia, POR was 1.8 and the 95% CI was 0.9-3.5. Among prostitutes in Oviedo, human immunodeficiency virus (HIV) prevalence was 4.9% and HIV-positive prostitutes showed a high risk of CIN as compared to HIV-negative prostitutes (POR, 12.7; 95% CI, 3.9-40.9); 76% of HIV-positive prostitutes were i.v. drug users and showed an increased seroprevalence of other sexually transmitted diseases. HIV-negative prostitutes did not show any increased risk of CIN (POR, 1.2; 95% CI, 0.5-2.8). These results show that among nonprostitutes the prevalence of CIN was not statistically different between the two cities in Spain and Colombia; prostitutes were at moderate increased risk compared to nonprostitutes in both cities.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
During the years 1990 to 1991, smears taken from the anal canal of 45 randomly selected homosexual males were studied. Several cytological criteria were used to study infection by human papillomavirus (HPV). The cytological study and an anoscopy was performed and a swab was taken for HPV-DNA hybridization, using labelled RNA probes for HPV-DNA: 6,11,16,18,31,33, and 35. In our study we observed the existence of a high proportion (9.5%) of inadequate smears that did not contain glandular cells and/or metaplasia. A sensitivity of 78% and a specificity of 72% was obtained. Sensitivity and specificity were 68% and 91%, respectively, when these criteria were restricted to the presence of koilocytes and/or dyskeratocytes. The high rate of occult infections obtained in our study lead us to suggest the simultaneous use of cytology, molecular hybridization, and anoscopy for suitable care of those patients with a high risk of contracting HPV infections of the anal canal.

Abstract
Eighty-nine women prostitutes who underwent clinical and microbiologic examination were found to have gonococcal infection. The median age was 22; 92.1% were from urban areas. Nearly all the women prostitutes refrained from barrier methods (92.1%) and had contact with several partners (91.0%). The most frequent clinical findings were leukorrhea (50.6%), cervicitis (20.2%), and pelvic inflammatory disease (PID) (18.0%). Eighty-one women prostitutes (93.1%) had experienced a previous STD, with Chlamydia trachomatis (34.8%), Trichomonas vaginalis (30.3%), Neisseria gonorrhoeae (29.2%), and Ureaplasma urealyticum (23.6%) as the most frequent microorganisms isolated. Microorganisms associated with N. gonorrhoeae were isolated, mainly T. vaginalis (40.4%), C. trachomatis (31.5%), and Mycoplasma hominis (21.3%). For N. gonorrhoeae, the most frequent auxotypes were prototrophic (67.4%) and Proline (Pro)-dependent (14.6%); 2.2% of the strains were non-auxotypable. Beta-lactamase production was detected in three strains (3.4%) belonging to the auxotype/serovar: Lys/IA, Prototrophic/IB, and Pro/IB. The two former produced the 3.2-MDa "African" plasmid; the latter produced two plasmids (the 4.5-MDa "Asian" and the 24.5-MDa transfer plasmid.
