Prevalence and Risk Factors of Chlamydia trachomatis Cervicitis in Pregnant Women at the Genital Tract Infection in Obstetrics Unit Care at Botucatu Medical School, São Paulo State University - UNESP, Brazil

Objective. To evaluate the prevalence of and risk factors for Chlamydia trachomatis cervicitis in pregnant women seen at the Genital Tract Infection in Obstetrics Unit Care in Botucatu Medical School, São Paulo State University - UNESP.Materials and Methods. Between June 2006 and February 2008, 101 pregnant women were included in this study. During the gynecologic examination, cervical secretions were collected using cytobrush Plus GT (CooperSurgical Inc) to assess C. trachomatis using polymerase chain reaction. Vaginal flora were examined by Gram stain, and socio-demographic data were extracted from medical records.Results. of the 101 patients, 26 (25.7%) were positive for C. trachomatis. The median age of the infected group was 24 years (range = 13-40 y), and 48.5% of them had abnormal vaginal flora. The presence of chlamydial infection was associated with smoking (odds ratio [OR] = 2.67, 95% confidence interval [CI] = 1.01-7.19), residing in a city with fewer than 100,000 inhabitants (OR = 2.86, 95% CI = 1.03-7.94), presence of condyloma acuminatum (p = .03), and presence of discreet inflammation on Pap smear (p = .02).Conclusions. The prevalence of C. trachomatis is high in pregnant women seen at the Genital Infection Unit Care, UNESP, and is related to many risk factors. Therefore, its screening is extremely important in reducing obstetrical and neonatal complications.

Serum and urinary measurements of prostatic acid phosphatase (PAP) and prostatic specific antigen (PSA) in dogs

Realizaram-se mensurações sérica e urinária de fosfatase ácida prostática (PAP) e antígeno prostático específico (PSA) de 20 cães. Os testes de PAP e PSA foram feitos em um equipamento automatizado, com o uso de kits comerciais para humanos. A média de PAP sérico foi de 0,7U/l e urinário 0,U/l. As médias do PSA sérico e urinário foram 0,005ng/dL e 0,004ng/dl, respectivamente. A determinação do dois biomarcadores in vivo é uma nova opção de diagnóstico na medicina veterinária e os valores obtidos devem ser correlacionados com a lesão morfológica da próstata.

Comparative analysis of root surface smear layer removal by different etching modalities or erbium:yttrium-aluminum-garnet laser irradiation. A scanning electron microscopy study

The purpose of this study was to evaluate the effect of erbium:yttrium-aluminum-garnet (Er:YAG) laser (2.94 mu m) irradiation on the removal of root surface smear layer of extracted human teeth and to compare its efficacy with that of citric acid, ethylenediamine tetra-acetic acid (EDTA), or a gel containing a mixture of tetracycline hydrochloride (HCl) and citric acid, using scanning electron microscopy (SEM). Thirty human dentin specimens were randomly divided into six groups: G1 (control group), irrigated with 10 ml of physiologic saline solution; G2, conditioned with 24% citric acid gel; G3, conditioned with 24% EDTA gel; G4, conditioned with a 50% citric acid and tetracycline gel; G5, irradiated with Er:YAG laser (47 mJ/10 Hz/5.8 J/cm(2)/pulse); G6, irradiated with Er:YAG laser (83 mJ/10 Hz/10.3 J/cm(2)/pulse). Electron micrographs were obtained and analyzed according to a rating system. Statistical analysis was conducted with Kruskal-Wallis and Mann-Whitney tests (P < 0.05). G1 was statistically different from all the other groups; no statistically significant differences were observed between the Er:YAG laser groups and those undergoing the other treatment modalities. When the two Er:YAG laser groups were compared, the fluency of G6 was statistically more effective in smear layer removal than the one used in G5 (Mann-Whitney test, P < 0.01). Root surfaces irradiated by Er:YAG laser had more irregular contours than those treated by chemical agents. It can be concluded that all treatment modalities were effective in smear layer removal. The results of our study suggest that the Er:YAG laser can be safely used to condition diseased root surfaces effectively. Furthermore, the effect of Er:YAG laser irradiation on root surfaces should be evaluated in vivo so that its potential to enhance the healing of periodontal tissues can be assessed.

Evaluation of the Smear Layer and Hybrid Layer in Noncarious and Carious Dentin Prepared by Air Abrasion System and Diamond Tips

Purpose: To analyze the smear layer and the hybrid layer in noncarious and carious dentin prepared by different cutting instruments and restored with composite resin. Study design: Cavities were randomly prepared in 160 specimens (noncarious and artificial carious dentin) by high-speed diamond tips (KG Sorensen 1013), air abrasion system (Prepstart, Danville Engineering), ultrasonic tip (CVDentus 8.3231-1), and ultrasonic tip associated with ultrasonic cavitation by water for 10 s. Half of the cavities in each group were conditioned with 37% phosphoric acid for 15 s. The amount of smear layer and dentinal tubules present were analyzed using scanning electron microscopy and graded from 0 to 3. Cavities were prepared in another 20 noncarious specimens and 20 carious specimens and restored with adhesive composite resin system. The restorations were hemisected longitudinally and analyzed using scanning electron microscopy to evaluate the hybrid layer and resinous prolongation characteristics, using scores ranging from 1 to 6. Results: The data were statistically analyzed using Kruskal-Wallis and Dunn tests at 5% of significance level. There was evidence that the most efficient smear layer removal was the acid etching in the noncarious dentin and the water ultrasonic cavitation in the carious dentin. The hybrid layer formed on the noncarious and carious dentin prepared by the ultrasonic tip was more regular than in the specimens prepared by high-speed diamond tip, with many resinous prolongations. Conclusion: The ultrasonic tip seems to be a promising tool for carious dentin cavity preparation. Microsc. Res. Tech. 73:597-605, 2010. (C) 2009 Wiley-Liss, Inc.

A comparative SEM study of smear layer removal by detergents and EDTA on the root surface

The present study performed an SEM evaluation of the efficiency of the following detergents on smear layer removal on the root surface: sodium lauryl sulphate, Plax, castor oil, and EDTA 24%. Sodium lauryl sulphate did not remove the smear layer and showed the worst results of all detergents tested. Plax and castor-oil detergents showed similar results represented by partial removal of the smear layer; these results were better than those obtained in the control (physiologic serum) and sodium lauryl sulphate groups. Neutral EDTA 24% was the most efficient detergent for smear layer removal.
