    Aims We aimed to evaluate the elastographic features of Achilles tendon with Acoustic Radiation Force Impulse in patients with and without diabetic neuropathy. Methods According to the presence of peripheral neuropathy, 45 patients with type 2 diabetes were divided into 2 subgroups. Those with peripheral neuropathy were defined as group I (22 patients) and those without peripheral neuropathy were defined as group II (23 patients). A total of thirty age-, gender-, and body mass index-matched healthy individuals were selected as controls. All participants underwent both ultrasonographic and Acoustic Radiation Force Impulse elastographic examination in order to evaluate Achilles Tendon thickness and stiffness. Results Achilles tendon thicknesses were similar between groups (p = 0.991). Achilles tendon thicknesses of both patient groups were significantly higher than the control group (group I vs control p = 0.01; group II vs control p = 0.006). Stiffness values of Achilles tendons were similar between the control group and group II (p = 0.993). Shear Wave Velocity was significantly lower in group I than group II and control group (p < 0.001). Conclusion Diabetic patients with neuropathy have thicker and softer Achilles tendon while the elasticity of Achilles tendon in diabetic patients without neuropathy is similar to the healthy controls. Softening of the Achilles tendon may be an early sign of diabetic foot and reveal the patients with a risk of diabetic foot.

    Severe chronic periodontitis is not common in Acromegaly: Potential protective role of gingival BMP-2
    (2021) Bascil, Sibel; Turhan Iyidir, Ozlem; Bayraktar, Nilufer; Ertorer, Melek Eda; Bascil Tutuncu, Neslihan; 0000-0002-0225-2477; 0000-0001-5305-6807; 0000-0002-7886-3688; 0000-0001-7357-8709; 0000-0002-1816-3903; 33421969; K-7904-2019; Y-8758-2018; ABI-3705-2020; ABG-5027-2020
    Background/aim : Advanced chronic periodontitis is observed rarely in acromegaly. Periodontal tissue including the alveolar bone is seemed to be spared from the systemic metabolic derangements of bone in this patient population. Chronic elevation of growth hormone, IGF-1, and bone morphogenetic proteins may play a role in periodontal tissue regeneration in acromegalics. In this study, we aimed to evaluate the potential roles of local gingival bone morphogenetic proteins (BMP) in periodontal tissue pathology in acromegaly. Materials and methods: Thirty-five patients with acromegaly and 22 healthy subjects were recruited. All the participants were examined by the same periodontologist for the diagnosis of periodontal diseases. BMP-2 and-4 were studied in gingival crevicular fluid. Results: Gingival BMP-2 and BMP-4 levels were similar in acromegaly and control groups in general, with and without chronic periodontitis. For all the participants, gingival BMP-2 levels were statistically lower in those participants with chronic periodontitis then those without periodontitis (29.4 +/- 11.2 vs. 41.2 +/- 23.2, respectively, p = 0.027). Causal relation between the gingival BMP levels and periodontal tissue health status was tested with one way ANOVA which revealed a significant difference between gingival BMP-2 levels in those with different degrees of periodontal tissue pathology (p = 0.025). When analyzed separately, gingival BMP-2 levels revealed a causal relation with the degree of periodontal pathology with borderline significance only in patients with acromegaly (p = 0.057). Conclusion: Acromegaly is a disease with an unexpectedly low frequency of advanced periodontitis, irrespective of the long disease duration and pathognomonic oral manifestations. BMP-2 might have a protective role against chronic advanced periodontitis in these patients.
