Introduction: HTLV is a retrovirus with high prevalence in Salvador, Bahia, when compared to other Brazilian capitals. The study of its risk factors is very important in order to understand the infection dynamics in the municipality. Objective: To assess the prevalence and some risk factors for HTLV-I/II infection among people assisted by the Family Health Program (FHP) in Salvador, Bahia, Brazil. Materials and methods: Biological samples were obtained from FHP health centers in Salvador city. Immunoassays were performed by ELISA method for HTLV antibody detection. Retrospective data about potential risk factors to HTLV infection were obtained through questionnaire. Results: 765 samples were tested, 529 (69.2%) females and 236 (30.8%) males. The overall HTLV-I/II seroprevalence was 1.96%, increasing according to age. HTLV-I/II seroprevalence was 2.16% and 1.89% for males and females, respectively (p = 0.833). Among seropositive individuals, 84.6% reported having a steady sexual partner and 61.5% do not use condoms frequently in their sexual intercourses, what similarly was observed among seronegative with 76.5% and 67.4%, respectively. Conclusion: The seroprevalence found is considered high compared to other Brazilian municipalities. The analyzed risk factors were not statistically different between HTLV-I/II seronegative and seropositive groups. The vertical transmission was not an important factor for virus maintenance. Source

Sickle cell disease is characterized by several clinical and pathophysiological changes including painful leg ulcers. These are difficult to heal and require the support of a multidisciplinary team in their management. The treatment of pain in these patients usually involves the use of opioids. In order to reduce the use of systemic opioids, we evaluated an easy-to-use low-cost morphine gel (0.12%) that was applied before and after changing leg ulcer dressings of sickle cell patients treated in Hemorio hospital. Based on the Analogue Pain Scale (APS) we evaluated the analgesic effect of the gel with 28 patients. All presented with a degree of pain of 7 or 8 before applying the gel. A total absence of pain was observed by 24 patients (85.7%) within thirty minutes of applying the gel, with the analgesia effect being maintained for a period of 24 hours and thus the use of other analgesics was not requiring. In 3 patients (10.7%) no pain was reported for a period of 12 hours. Only 1 patient (3.6%) reported no analgesic effect thirty minutes after the application of the gel. Our results indicate that the morphine gel was effective in controlling the pain of leg ulcers in this group of sickle cell patients. A controlled study should be designed to assess this important subject. Source

Purpose: To evaluate the profile of all the visits to the ophthalmic emergency service at a tertiary hospital in the city of Sobral, Ceará, northeast of Brazil. Methods: A survey was carried out of all patients attended at ophthalmology emergency service of the department of ophthalmology of Santa Casa of Sobral, during the period between may and october 2008. Data on patient's age, sex, level of education, residential address, health insurance status, average distance to our service, time between the initial symptoms and first visit to the hospital, site of medical evaluation indication, diagnosis, and veracity of emergency indication. All these data were collected during interview and ophthalmological examination. Results: A total number of 1,024 patients were analyzed in the study. Mean and standard deviation to age was 31.5 ± 17.1 years (ranging from zero to 81). Sixty-five per cent of the patients were male and 35% female. Twenty-one per cent of the patients lived at least 50 kilometers away from the Santa Casa of Sobral. Ocular traumas (40.9%) of any nature were the most frequent occurrence, followed by infections (29%). About 45 % of cases were not considered as a true emergency and could be managed in primary or secondary health care centers. About the initial symptoms and first visit to the hospital, only 24% of the patients went to the ophthalmology emergency room on the same day in which their symptoms started. Conclusion: A great number of patients attended or treated at the ophthalmology emergency service of Santa Casa of Sobral presented with common ocular disorders of simple resolution. Therefore there is a failure in the primary and secondary health care to manage it. Certainly a considerable proportion of these patients had conditions which could have been diagnosed and treated in an ophthalmic outpatient clinic or by general practitioners. Source

Chagas' Disease is an endemic parasitic disease in South and Central America. There are two drugs available for medical treatment of the disease, Nifurtimox (Nfx) and Benznidazol (Bz). There are no standardized or accessible protocols in regional laboratorios to determine the levels of antichagasic drugs in blood. A spectrophotometric method for Nfx and Bz determination in blood is presented in the present work. Blood metabolites are extracted through Extrelut® columns. Extracts are evaporated, redissolved in metanol/water mixanalysed by spectrophotometry at 400 nm and 320 nm for Nfx and Bz, respectively. They are quantified comparing with standard Nfx or Bz solutions in the solvent. The methodology used was validated between 0.5 and 50 μg/mL of blood for Nfx, and between 0.5 and 100 μg/mL of blood for Bz. The accuracy, precision, lineality and robustness of the method were satisfactory. The procedure was applied determining blood concentrations after administration of both drugs to rats. Source

Introduction: Due to the ubiquity of nosocomial yeast infections of the genus Candida spp., studies in this area have become increasingly relevant. Objective: To evaluate the antifungal Candida spp. Susceptibility profile of hospitalized patients from the Regional University Hospital of Maringá-PR (HURM). Material and Methods: The samples were submitted to broth microdilution test (MD) according to protocol M27-A3 in order to determine the minimum inhibitory concentration (MIC) and disk diffusion test according to protocol M44-A2, both from Clinical Laboratory Standards Institute (CLSI). Results and discussion: We obtained 91 isolates from urine samples, blood culture, catheter tip, endotracheal secretions, among others, from which 38 were Candida albicans, 23 were C. tropicalis, 16 were C. gabrata, 10 were C. parapsilosis, and four were C. krusei. Among the tested antifungal medications, amphotericin B, voriconazole and anidulafungin proved to be the most effective. Conclusion: In the comparison between broth microdilution and disk diffusion (DD) methods, fluconazole showed good correlation for most Candida spp., which corroborates the usefulness of DD in the screening of main antifungal agents used in clinical practice. Nonetheless, cases of resistance detected by DD need to be confirmed by MD method, which avoids false-resistant results and maximizes the treatment efficacy and reliability. Source
