Early post-LASIK flap amputation in the treatment of aggressive, branching keratitis: a case report / Amputação precoce de pedículo de LASIK para o tratamento de ceratite ramificada agressiva: relato de caso

ABSTRACT Infectious keratitis is rare following laser vision correction. We present a case of aggressive fungal keratitis caused by Aspergillus flavus, following laser in situ keratomileusis (LASIK) in the setting of a unique environmental risk factor. We describe the key features of the acute case presentation, which guided empirical medical and surgical treatment, resulting in the most favorable outcome found in the literature, to date.

RESUMO Ceratites infecciosas são raras após a correção da visão a laser. Apresentamos um relato de caso de uma ceratite fúngica agressivo por Aspergillus flavus, após ceratomileuse a laser "in situ" (LASIK) em situação peculiar de fator de risco ambiental. Nós descrevemos as principais características da apresentação caso agudo, que orientou tratamento médico e cirúrgico empírico, demonstrando resultado mais favorável do que o encontrado na literatura até o momento.

Changes in the subgingival biofilm composition after coronally positioned flap

OBJECTIVES: This study evaluated the effects of coronally positioned flap (CPF) on the subgingival biofilm composition. MATERIAL AND METHODS: Twenty-two subjects with gingival recessions were treated with CPF. Clinical parameters were assessed before and at 6 months after surgery. Subgingival biofilms were analyzed by checkerboard DNA-DNA hybridization technique for 40 bacterial species. RESULTS: Recession height, clinical attachment level and bleeding on probing improved significantly (p<0.05) at 6 months post-CPF. The proportions of 10 periodontal pathogens and the proportions of red and orange complexes decreased at 6 months. CONCLUSION: In conclusion, CPF can induce beneficial effects on the composition of the subgingival microbiota after 6 months.
