Ensaio randomizado, duplo-cego e controlado de anestesia tópica induzida por iontoforese de lidocaína

Introduction: Needle infi ltration of local anesthetic is a painful procedure, thus, a topical anesthetic is a comfortable alternative; however, it is diffi cult to deliver transcutaneous polar drugs. Iontophoresis is a noninvasive technique that uses electrical current for releasing electrically charged drugs through biological membranes. Objective: To evaluate the anesthesia induced by iontophoresis of lidocaine for a standardized painful stimulus. Material and methods: Randomized, controlled, double-blind study, involving 10 volunteers under the anesthetic effects of topical application of lidocaine gel 2% and noradrenaline 1:50,000, with or without iontophoresis of 1.85 milliamps for 13 minutes. Pain sensitivity was evaluated by the prick of a 21G needle in the arms posterior region, using a visual numerical scale. Results: Patients mean age was 50.8 ± 11.4 years. Nine of them were women. All had previously received infi ltrative anesthesia. Iontophoresis was well tolerated by volunteers. The median pain scores were 0 and 3 for the arm that received the iontophoresis and for the one that did not receive, respectively (p < 0.01). Conclusion: The anesthetic effect in the region subjected to iontophoresis suggests an effi cient and comfortable method for promoting local anesthesia in the surgical approach of pediatric, hyperalgic, or needlephobic patients.

Acesso a medicamentos essenciais em farmácias e drogarias do Município de Araraquara

A survey to determine the availability of 20 essential medicines for the diseases with highest prevalence in primary health care was conducted in the city of Araraquara. The presence and the price of these medicines in private sector pharmacies and drugstores of the city were recorded. Two forms, recommended by the WHO, were used in the survey, one for availability and the other for prices. The drugs most commonly available in pharmacies and drugstores were: propranolol (90.5%), captopril (96%) and ranitidine (96%), while the least available were ferrous sulfate (27%), beclomethasone (33.8%) and ibuprofen (41.9%). The drugs that showed the greatest variation among the prices charged were: propranolol (97.1%), hydrochlorothiazide (96.4%) and glibenclamide (95.0%), while the least variable were salbutamol (30.8%) and trimethoprim-sulfamethoxazole (30.2%). Generic drugs, which were half (10) of those assessed, had the lowest prices. The indicators of access, referring to the ability of patients to acquire drugs for the treatment of major diseases at the primary health care level, showed that no establishment stocked all 20 essential drugs and that wide variations existed in their prices, undermining their availability to drug users, whose only sources are pharmacies and drugstores. These data demonstrate the importance of the popular pharmacy to improve the access to medicines, by lowering the cost and increasing the availability of the items selected for the National List of Essential Drugs (RENAME).

Estimativa do tempo de produção de chorume em aterro controlado por meio de medidas de resistividade elétrica

Landfill is an engineering work that aims at to accommodate residues in the smallest possible space in the soil, with minimum damages to the environment and the public health. One in the constructive forms of a controlled landfill is the excavation of ditches with appropriate dimensions, for disposition of solid residues without compactation or impermeabilization. Liquid effluents generated for similar volumes of residues, disposed in ditches with ages different from closing, it should result in physical and chemical alterations you correlated at the time of residence materials. With base in this hypothesis, measures of electric resistivity were accomplished through the of Eletrical Resistivity geophysical method, on residues ditches closed annually between 12/2001 and 12/2007, localized in control landfill of the Cordeirópolis city (SP). The leachate is a liquid effluent generated by the decomposition of organic matter and characterized by high content in total dissolved solids, whose interaction with geological environment results in alterations in terms of electrical resistivity susceptible to detection for the geophysical instrumental. The results suggest a resistivity reduction for leachate percolation produced for ditches recently and increase progressive of the resistivity for older ditches. The statistical comparative analysis with reference values for the area suggests ages of the finish production and percolation leachate for soil and rock below the ditches.
