Peripheral giant cell reparative granuloma is a reactive and rare lesion of oral cavity with unknown etiology which is derived from periosteum and periodontal ligament and occurs frequently in young adults. Inflammation or trauma is underlying causative factor of reactive proliferation. In the present case report, a 35 year-old male with aggressive periodontitis and peripheral giant cell reparative granuloma is presented. The patient applied to our clinic with a complaining about a big nodule at his palate. The lesion was pedunculated and localized at his right maxilla between #16 and #17 which arose from distal aspect of #16, and the surface of the lesion was hyperkeratotic and the lesion was measured 22 x 30 mm at the largest diameter. He also had severe generalized aggressive periodontitis and hypertension. Amoxicillin clavulanate 625 mg, three times a day, metronidazole 500 mg three times a day and 0.2% chlorhexidine digluconate oral rinse, twice a day for a week, were prescribed to the patient. Then, scaling and root planing were performed along with systemic antibiotic treatment and he scheduled for surgery. The lesion was excised completely and #16 was extracted. After the healing period, periodontal surgery was planned for the treatment of aggressive periodontitis. Obtained tissue specimen was sent for histopathological examination. The diagnosis of peripheral giant cell reparative granuloma was confirmed with histopathological examination. No intra- and post-operative complications were seen.

Background Pediatric hypertension is recognized as an emerging global health concern. Although new guidelines are developed for facilitating clinical management, the reasons for the prevalence of hypertension in children remain unknown. Genetics and environmental factors do not fully account for the growing incidence of pediatric hypertension. Because stable bacterial flora in early life are linked with health outcomes later in life, we hypothesized that reshaping of gut microbiota in early life affects blood pressure (BP) of pediatric subjects. Methods and Results To test this hypothesis, we administered amoxicillin, the most commonly prescribed pediatric antibiotic, to alter gut microbiota of young, genetically hypertensive rats (study 1) and dams during gestation and lactation (study 2) and recorded their BP. Reshaping of microbiota with reductions in Firmicutes/Bacteriodetes ratio were observed. Amoxicillin treated rats had lower BP compared with untreated rats. In young rats treated with amoxicillin, the lowering effect on BP persisted even after antibiotics were discontinued. Similarly, offspring from dams treated with amoxicillin showed lower systolic BP compared with control rats. Remarkably, in all cases, a decrease in BP was associated with lowering of Veillonellaceae, which are succinate-producing bacteria. Elevated plasma succinate is reported in hypertension. Accordingly, serum succinate was measured and found lower in animals treated with amoxicillin. Conclusions Our results demonstrate a direct correlation between succinate-producing gut microbiota and early development of hypertension and indicate that reshaping gut microbiota, especially by depleting succinate-producing microbiota early in life, may have long-term benefits for hypertension-prone individuals.
