CREST Syndrome in Systemic Sclerosis Patients - Is Dystrophic Calcinosis a Key Element to a Positive Diagnosis? J Inflamm Res 2022; 15:3387-3394.

Abstract
Introduction CREST syndrome is a clinical entity associated with systemic sclerosis, which meets at least three of the five clinical features: calcinosis, Raynaud’s phenomenon, esophageal dysmotility, sclerodactyly, and telangiectasia. Three of these clinical features (Raynaud’s phenomenon, sclerodactyly and esophageal dysmotility) are often present in classical subsets of SSc: limited and diffuse, and their presence in association does not define CREST syndrome. Calcinosis seems to be less common in SSc and its association with other clinical features is characteristic of CREST syndrome. Therefore, it can be appreciated that calcinosis is the key element of CREST syndrome. Methods This study included a number of 37 candidates with SSc, diagnosed with the help of the American College of Rheumatology (ACR)/European League Against Rheumatism (EULAR) 2013 criteria. Results and Discussions These three elements (calcinosis, Raynaud’s phenomenon, esophageal dysmotility) were recorded both in the limited subset of SSc, but especially in the subset of diffuse SSc, contrary to the data in the literature. Conclusion We appreciate that CREST syndrome is a clinical entity that can overlap with both subsets of SSc. Given the divergent views of the authors on the classification of CREST syndrome, future studies may contribute to a reassessment of SSc classification.

Impact of Inorganic Xenograft on Bone Healing and Osseointegration: An Experimental Study in Rabbits. IMPLANT DENT 2018; 26:875-881.

Abstract
PURPOSE To evaluate if an inorganic graft applied before implant insertion interferes with osseointegration. MATERIALS AND METHODS The bilateral mandibular incisors of 12 rabbits were extracted. One of the sockets was randomly filled with an inorganic xenogenic bone graft, whereas the remaining socket was allowed to heal naturally and served as a control. After 60 days, titanium implants were inserted into healing areas. The animals were killed 60 days after. Bone depositions were marked with fluorochrome oxytetracycline, alizarin, and calcein and evaluated using confocal laser scanning microscopy. Bone-to-implant contact (BIC) and bone area (BA) within the limits of the implant threads were analyzed. Data were compared statically by paired t tests, one-way ANOVA, and Bonferroni post hoc tests (α = 0.05). RESULTS No differences between the control and experimental groups in bone deposition for each marker, in either the BIC or BA analysis were observed. The bone deposition marked by alizarin (14-21 days) was the highest, followed by oxytetracycline (0 and 7 days) and calcein (45 and 52 days) in both groups (P < 0.05). CONCLUSION The bone healing or the course of osseointegration was not impaired by the use of an inorganic xenogenic graft before insertion of a titanium implant.

Abstract
After tumor resection, bone reconstruction such as skull base reconstruction using interconnected porous structure is absolutely necessary. In this study, porous scaffolds for bone reconstruction were prepared using heat-pressing and salt-leaching methods. High-density polyethylene (HDPE) and poly(ethylene-co-acrylic acid) (PEAA) were chosen as the polymer composites for producing a porous scaffold of high mechanical strength and having high reactivity with biomaterials such as collagen, respectively. The porous structure was observed through surface images, and its intrusion volume and porosity were measured. Owing to the carboxylic acids on PEAA, collagen was successfully grafted onto the porous HDPE/PEAA scaffold, which was confirmed by FT-IR spectroscopy and electron spectroscopy for chemical analysis. Osteoblasts were cultured on the collagen-grafted porous scaffold, and their adhesion, proliferation, and differentiation were investigated. The high viability and growth of the osteoblasts suggest that the collagen-grafted porous HDPE/PEAA is a promising scaffold material for bone generation.

Abstract
The implant-to-tissue interface is an extremely dynamic region of interaction. Generally, a surgical procedure is performed on a patient to insert a foreign material into the bone, and the body is called on to “heal” the wound. The time schedule crucial for a healing process that is expected to result in restitution ad integrum must be determined with respect to the condition of the individual patient and tissue to be treated. There are various factors responsible for the formation of an adequate bone–implant interface. A comprehensive review of the response of bone to implant is described.

Abstract
OBJECTIVES The aim of this study was to conduct a comparative qualitative and quantitative assessment of the interfacial soft and hard tissues investing implants and natural teeth. MATERIALS AND METHODS The test sample consisted of six adult healthy male Macaca fascicularis with three-unit splinted crowns, each crown supported by an Ankylos screw-shaped titanium implant. These implants were placed in the mandibular premolar-second molar region, one side by an immediate-loading (IL) and the other by delayed-loading (DL) protocol. The animals were sacrificed after 3 months of functional loading. Another two monkeys with natural dentition served as controls. Nondecalcified sections were prepared for assessment of optical intensities (OI) under a confocal laser scanning microscope. RESULTS In both the test (IL and DL) and control, the soft tissue complexes demonstrated a highly fluorescent keratinized layer and diminished cytoplasmic and enhanced membranous fluorescence in the remaining epithelium. Peri-implant mucosa was further characterized by an intense fluorescence at the junctional epithelium-implant interface and in the stromal mononuclear infiltrate. Connective tissue contact and periodontal ligament were weakly fluorescent. In hard tissues, a high fluorescence was observed in peri-implant woven bone and along the implant-bone interface. Mean OI was significantly higher in peri-implant woven bone than around teeth (P < 0.05). In the remaining soft and hard tissue complexes, no significant differences in mean OI between the test and control were observed (P > 0.05). CONCLUSIONS Present findings suggest that peri-implant woven bone is highly mineralized, while the peri-implant and gingival mucosa share structural similarities. CLINICAL RELEVANCE Optical intensities of interfacial tissues investing implants and teeth are related to their biological properties.

Abstract
Bone is a mineralized connective tissue that is continuously and microstructurally remodeled. Altered bone formation and microstructure arise in pathological bone conditions such as osteoporosis, osteonecrosis, fracture repair, and Paget disease of bone. A proper and objective assessment of bone formation and microstructure will provide insight into the understanding of bone pathogenesis and remodeling. Here, new bone formation ex vitro and its microstructure were evaluated in in vivo multiple sequential polychrome-labeled samples using confocal laser scanning microscopy (CLSM), which generated clearer and more reliable images of thick bone sections than conventional fluorescence microscopy (CFM). Intriguingly, fine details of the bone microstructural features, including the mineralization fronts, quiescent versus active osteons, and Volkmann's channel, were elucidated using CLSM, which defines the relationship between morphological changes and function, when combined with differential interference contrast microscopy. Furthermore, CLSM provided objective evaluations of bone formation, such as the ratio of labeled areas of new bone formation in a rabbit model when compared with CFM. Altogether, new bone formation and its microstructure can be evaluated more adequately using a combination of CLSM and DIC microscopies.
