Infliximabe no tratamento inicial da retocolite ulcerativa moderada e grave. Terapia top down: Relato preliminar

The first option for the treatment of UC is both: salicylates or corticoids. Recently, in late November of 2006, the Brazilian Ministry of Health has approved infliximab (Remicade c, Mantecorp, Brazil) to treat ulcerative colitis. We report the use of infliximab as a first option for the treatment of two patients with severe ulcerative colitis. Case report: Patient 1: AZF, 52 years-old, female, was first diagnosed with UC after history and clinical examination; colonoscopy showed pancolitis with positive biopsy (crypt microabscess). Her Mayo score was 10 (range: 0 to 12/asymptomatic to severe colitis). She received intra venous infusion of infliximab at a dose of 5mg/Kg of body weigh at week 0, 2, 6 and 14. Then, patient was given mesalazine 4.5 g/day for maintenance therapy. Clinical response was defined as a decreased from baseline in the total Mayo score of at least 3 points. At present, patient is asymptomatic with Mayo score of 3 one moth after the last dose of infliximab. Patient 2: MLA, 45 years-old, female was first diagnosed with bloody diarrhea; colonoscopy showed left colitis and the biopsy was positive for ulcerative colitis. Her Mayo score was 9. She was offered and accepted the step down treatment. She was given infliximab 5mg/Kg of body weight at week 0, 2, 6 and 14. After initial treatment with infliximab, she received mesalazine 4.2 g/day. At present, she is asymptomatic with Mayo score of 2 eighteen days after the last dose of infliximab. At our knowledge, this is the first Brazilian report of the use of infliximab as fist-line therapy in ulcerative colitis. Few days after the begging of the infusion, an impressive clinical and colonoscopy improvement was seen in these two patients. Recently, it has been reported the use of infliximab as first-line therapy in pediatric Crohn disease. Infliximab could be a good option in cases of moderate and severe UC to avoid the side effects of the use of high doses of corticoids in patients with moderate and severe UC. However, the question if step-down therapy in ulcerative colitis is better then conventional therapy with salicylates and corticoids needs to be answered by randomized trials.

Estudo clínico randomizado, aberto e comparativo para avaliação de segurança, tolerabilidade e eficácia analgésica de duas diferentes apresentações de medicamento tópico na realização de curetagem dermatológica de molusco contagioso em pacientes pediátricos

Aim: This study aimed to compare the safety and analgesic efficacy of a new topical drug (in two different presentations: cream and aerosol) consisting of benzocaine, menthol and triclosan, in the curettage of molluscum contagiosum. Method: The study included 296 volunteers in different stages: 256 healthy adult volunteers for the safety evaluation, and 40 volunteers between 2 and 12 years old who presented Molluscum contagiosum, for the evaluation of tolerability and efficacy. Each volunteer represented two experimental units (left and right) where it was applied randomly the tested products (cream or aerosol) 30 minutes before the dermatological curettage, immediately after and twice a day during 7 days. Dermatological evaluations of safety and efficacy were performed immediately after the procedure, 3 and 7 days after the curettage. Results: During safety evaluation, the tested products showed no irritant, sensitizing, phototoxic or photosensitizing potential. Both presentations, cream and aerosol, were considered safe with no statistically significant differences between them. With respect to analgesic efficacy, the results showed that the medication promoted the reduction of painful symptoms and there was no statistically significant difference (p <0.05) between the two presentations. Conclusion: The tested product, in two different presentations, was considered safe and effective in controlling pain symptoms during and after the curettage of molluscum contagiosum. © Copyright Moreira Jr. Editora.

Effects of active smoking on airway and systemic inflammation profiles in patients with chronic obstructive pulmonary disease

Background: The markers that characterize local and systemic inflammation in chronic obstructive pulmonary disease (COPD) remain unclear, as do their correlations with smoking status and presence of disease. The aim of this study was to assess markers of inflammation in the peripheral blood and airways of current smokers without COPD, of current smokers with COPD and of ex-smokers with COPD. METHODS: In this study, 17 current smokers with COPD (mean age: 58.2 ± 9.6 years; mean forced expiratory volume in 1 second [FEV1]: 56.1 ± 15.9%), 35 ex-smokers with COPD (mean age: 66.3 ± 7.3 years; mean FEV1: 47.9 ± 17.2%) and 20 current smokers without COPD (mean age: 49.1 ± 6.2 years; mean FEV1: 106.5 ± 15.8%) were evaluated. Spirometry findings, body composition and serum/induced sputum concentrations of tumor necrosis factor α (TNF-α), interleukin (IL)-6, IL-8 and IL-10, together with serum C-reactive protein (CRP) levels, were assessed. RESULTS: Serum TNF-α concentration was higher in all current smokers than in ex-smokers with COPD. In current smokers without COPD, serum CRP level was lower than in ex-smokers with COPD and significantly lower than in current smokers with COPD. Sputum TNF-α concentration was higher in current and ex-smokers with COPD than in current smokers without COPD. Multiple regression analyses showed that serum TNF-α was associated with active smoking, and serum CRP and sputum TNF-α were associated with COPD diagnosis. CONCLUSIONS: Smoking is associated with higher systemic inflammation in patients with COPD. Current findings also support the hypothesis that smoking and COPD have different effects on the regulation of airway and systemic inflammatory processes. © 2013 Lippincott Williams and Wilkins.

Effects of soy isoflavones on mammographic density and breast parenchyma in postmenopausal women: A randomized, double-blind, placebo-controlled clinical trial

OBJECTIVE: This study aims to evaluate the effects of soy isoflavones on breast tissue in postmenopausal women. METHODS: In this randomized, double-blind, placebo-controlled study, 80 women (aged ≥45 y and with amenorrhea >12 mo) with vasomotor symptoms were randomized to receive either 250 mg of standardized soy extract corresponding to isoflavone 100 mg/day (n = 40) or placebo (n = 40) for 10 months. Breasts were evaluated through mammographic density and breast parenchyma using ultrasound (US) at baseline and 10-month follow-up. Independent t test, analysis of variance, Mann-Whitney U test, and χ2 trend test were used in statistical analysis. RESULTS: Baseline clinical characteristics showed no significant differences between the isoflavone group and the placebo group, with mean (SD) age of 55.1 (6.0) and 56.2 (7.7) years, mean (SD) menopause duration of 6.6 (4.8) and 7.1 (4.2) years, and mean (SD) body mass index of 29.7 (5.0) and 28.5 (4.9) kg/m2, respectively (P > 0.05). The study was completed by 32 women on isoflavone and 34 women on placebo. The groups did not differ in mammographic density or breast parenchyma by US (P > 0.05). Within each group, the baseline and final moments did not differ in mammography or US parameters significantly (P > 0.05). CONCLUSIONS: The use of soy isoflavone extract for 10 months does not affect breast density, as assessed by mammography and US, in postmenopausal women. © 2013 by The North American Menopause Society.

Ultrasound evaluation of common carotid artery blood flow in the Labrador retriever

Background: Doppler ultrasound (DUS) examination provides quantitative and qualitative information concerning the blood flow in veins and arteries, enabling their morphological evaluation and the collection of hemodynamic data. Dogs and cats as well as humans may display neurological signs of brain hypoperfusion secondary to common carotid alterations. Hence, DUS examination might aid in the differential diagnosis of neurological disorders of ischemic origin, among other causes. The objective of this study was to register normal values for systolic peak velocity, minimum diastolic velocity, diameter and resistance index of both common carotid arteries of 12 healthy Labrador retriever dogs between 2 and 5 years of age. By gathering these values, we might be able to improve the sensitivity of hemodynamic studies in clinically important brain disorders. Results: There were no statistical differences between the values for the right and left vessels: the systolic peak velocity was 75.8 ± 16 cm/s, minimum diastolic velocity was 12.2 ± 4 cm/s, common carotid diameter was 0.545 ± 0.063 cm, and resistance index was 0.83 ± 0.07. Conclusions: The results of this study might be used to establish normal parameters for Labrador retriever dogs and thus help in the diagnosis of neurological disorders associated with alterations of the carotid arteries. Similar studies must be performed to evaluate the same parameters in other dog breeds of different sizes and skull conformations. © 2013 Svicero et al.; licensee BioMed Central Ltd.
