Raynaud phenomenon and microvasculopathy in systemic sclerosis: multi-modality imaging for diagnosis and evaluation

Vascular, Soft Tissue, and Musculoskeletal Imaging in Systemic Sclerosis

This review examines the role of various imaging techniques in assessing vascular and musculoskeletal manifestations in Systemic Sclerosis (SSc). Imaging modalities, such as thermography, capillaroscopy, ultrasound, optical coherence tomography, laser speckle contrast analysis, radiography, computed tomography, and MRI, offer valuable insights into SSc-related complications. Findings suggest that these techniques aid in diagnosing conditions like Raynaud phenomenon, digital ulcers, calcinosis, acro-osteolysis, and hand contractures. However, each modality has its advantages and limitations, necessitating a multimodal approach for comprehensive evaluation and accurate diagnosis of SSc-related manifestations.

Complete Dental Implant Restoration in an Individual With Systemic Sclerosis and Microstomia: A Case Report

Background: Systemic sclerosis (SS) is a debilitating disease that affects oral and any other tissues including skin, bone, blood vessels, and the connective tissues by excessive collagen accumulation. It is a difficult case for oral rehabilitation, let alone dental implantation. In this regard, only few studies have been conducted. This article reports a case of full-mouth implant-supported prostheses in a SS patient. Case: After diagnosing most remaining teeth as hopeless through clinical and radiographic examinations, implant-based fixed prosthesis for both jaws was planned, considering the progressive microstomia. Hopeless teeth were extracted. In the maxilla, the areas of central incisors, canines, first premolars, and first molars were implanted. In the mandible, the areas of the lateral incisors and the right second premolar were implanted. Also, according to the surgeon's opinion, the anterior mandible needed bone grafting. After 3 months, the prosthetic treatment was started. Because in scleroderma, the limitation of mouth opening is progressive (and also in order to allow the restoration of the prosthesis in the future), screw-retained abutments were used for the posterior segment. Nevertheless, the anterior abutments were cement-retained. Result: The patient was followed up until the present time (for 3 years). In these follow-ups, no bone resorption was observed, and the treatment was deemed successful. Conclusion: This report suggests that dental implants might be successful and safe for at least some cases of systemic scleredema.

Coronary microvascular dysfunction

Coronary microvascular dysfunction (CMD) is a key mechanism underlying ischemic heart disease (IHD), yet its diagnosis and treatment remain challenging. This article presents a comprehensive overview of CMD research, covering its pathogenesis, diagnostic criteria, assessment techniques, risk factors, and therapeutic strategies. Additionally, it highlights the prospects for future CMD research. The article aims at advocating early and effective intervention for CMD and improving the prognosis of IHD.
