| 1 | Enamel microabrasion: An overview of clinical and scientific considerations显示文摘Superficial stains and irregularities of the enamelare generally what prompt patients to seek dental intervention to improve their smile. These stains or defects may be due to hypoplasia, amelogenesis imperfecta, mineralized white spots, or fluorosis, for which enamel microabrasion is primarily indicated. Enamel microabrasion involves the use of acidic and abrasive agents, such as with 37% phosphoric acid and pumice or 6% hydrochloric acid and silica, applied to the altered enamel surface with mechanical pressure from a rubber cup coupled to a rotatory mandrel of a lowrotation micromotor. If necessary, this treatment can be safely combined with bleaching for better esthetic results. Recent studies show that microabrasion is a conservative treatment when the enamel wear is minimal and clinically imperceptible. The most important factor contributing to the success of enamel microabrasion is the depth of the defect, as deeper, opaque stains, such as those resulting from hypoplasia, cannot be resolved with microabrasion, and require a restorative approach. Surface enamel alterations that result from microabrasion, such as roughness and microhardness, are easily restored by saliva. Clinical studies support the efficacy and longevity of this safe and minimally invasive treatment. The present article presents the clinical and scientific aspects concerning the microabrasion technique, and discusses the indications for and effects of the treatment, including recent works describing microscopic and clinical evaluations. | Núbia Inocencya Pavesi Pini Daniel Sundfeld-Neto Flavio Henrique Baggio Aguiar Renato Herman Sundfeld Luis Roberto Marcondes Martins José Roberto Lovadino Débora Alves Nunes Leite Lima | 2015 | World Journal of Clinical Cases2015，3，1： | 6 |
| 2 | Combination of corticosteroids and 5-aminosalicylates or corticosteroids alone for patients with moderate-severe active ulcerative colitis:A global survey of physicians'practice显示文摘AIM To examine treatment decisions of gastroenterologists regarding the choice of prescribing 5-aminosalycilates(5ASA) with corticosteroids(CS) versus corticosteroids alone for patients with active ulcerative colitis(UC). METHODS A cross-sectional questionnaire exploring physicians' attitude toward 5ASA + CS combination therapy vs CS alone was developed and validated. The questionnaire was distributed to gastroenterology experts in twelve countries in five continents. Respondents' agreement with stated treatment choices were assessed by standardized Likert scale. Background professional characteristics of respondents were analyzed for correlation with responses. RESULTS Six hundred and sixty-four questionnaires were distributed and 349 received(52.6% response rate). Of 340 eligible respondents, 221(65%) would continue 5ASA in a patient hospitalized for intravenous CS treatment due to a moderate-severe UC flare, while 108(32%) would stop the 5ASA(P < 0.001), and 11(3%) are undecided. Similarly, 62% would continue 5ASA in an out-patient starting oral CS. However, only 140/340(41%) would proactively start 5ASA in a hospitalized patient not receiving 5ASA before admission. Most(94%) physicians consider the safety profile of 5ASA as very good. Only 52% consider them inexpensive, 35% perceive them to be expensive and 12% are undecided. On multi-variable analysis, less years of practice and perception of a plausible additive mechanistic effect of 5ASA + CS were positively associated with the decision to continue 5ASA with CS. CONCLUSION Despite the absence of data supporting its benefit, most gastroenterologists endorse combination of 5ASA + CS for patients with active moderate-to-severe UC. Randomized controlled trials are needed to assess if 5ASA confer any benefit for these patients. | Shomron Ben-Horin Jane M Andrews Konstantinos H Katsanos Florian Rieder Flavio Steinwurz Konstantinos Karmiris Jae Hee Cheon Gordon William Moran Monica Cesarini Christian D Stone Doron Schwartz Marijana Protic Xavier Roblin Giulia Roda Min-Hu Chen Ofir Har-Noy Charles N Bernstein | 2017 | World Journal of Gastroenterology2017，23，16： | 3 |
