Perimenstrual asthma: Report of a case with therapeutic intervention of oral prednisone.

INTRODUCTION: Many asthmatic women of childbearing age experience cyclical aggravation of asthmatic symptoms during the perimenstrual period, or perimenstrual asthma (PMA). PMA is considered to be a difficult-to-treat asthma phenotype; conventional asthma therapies are not always effective against PMA. CASE STUDY: We report a case of a 27-year-old female with PMA who had received standard asthma treatment since 2013. RESULT: The patient showed a dramatic response to therapeutic intervention of oral prednisone, taken for 7 days prior to menstruation each month, in a dose-dependent manner. CONCLUSION: Premenstrual treatment with oral prednisone may be a successful new direction for the treatment of PMA, a troublesome type of asthma.

[Decalcified freeze-dried bone allograft combined with rich platelet derivatives for the treatment of human periodontal intrabony defects: a Meta-analysis].

OBJECTIVE: This review aims to systematically evaluate the effect of decalcified freeze-dried bone allograft (DFDBA) combined with rich platelet derivatives on the treatment of human periodontal intrabony defects. METHODS: A search in PubMed, Web of Science, Embase, Cochrane Library, CNKI, and other electronic databases was conducted to identify randomized controlled trials (RCT) of the use of DFDBA combined with rich platelet derivatives in the treatment of human periodontal intrabony defects, performed before May 2016. The quality of the RCTs was assessed. RevMan 5.3 software was applied for Meta-analysis. RESULTS: A total of nine RCTs were included. A total of 194 patients and 303 defects were involved. Short-term (6 months) and long-term (12 to 18 months) groups were included. Meta-analysis results revealed that DFDBA combined with rich platelet derivatives was superior to DFDBA or rich platelet derivatives alone for probing depth reduction in the short-term [MD=0.75 mm, 95% confidence intervals (CI) (0.31 mm, 1.20 mm), P=0.001 0] and longterm groups [MD=0.87 mm, 95%CI (0.02 mm, 1.72 mm), P=0.04], clinical attachment level gain in the short-term [MD=
0.65 mm, 95%CI (0.08 mm, 1.22 mm), P=0.03] and long-term groups [MD=1.31 mm, 95%CI (0.60 mm, 2.01 mm), P<0.000 3], gingival recession reduction in the long-term group [MD=-0.58 mm, 95%CI (-0.78 mm, -0.38mm), P<0.000 01], bone fill gain in the short-term [MD=0.52 mm, 95%CI (0.03 mm, 1.00 mm), P=0.04] and long-term groups [MD=1.26 mm, 95%CI (0.65 mm, 1.86 mm), P<0.000 1]. CONCLUSIONS: DFDBA combined with platelet rich derivatives is probably effective in the treatment of human periodontal intrabony defects. It is probably superior to DFDBA or platelet rich derivatives alone. Considering the limitation of the included studies, high-quality and large-sample RCTs are required to evaluate the effect.
