Introduction: Tooth extraction initiates a cascade of homeostatic and structural modifications within the periodontal tissues, culminating in alveolar ridge resorption. To prevent ridge resorption following extraction and facilitate successful placement of an implant-supported prosthesis, alveolar ridge preservation was performed.
Methods: In this study, the biocompatibility of a nanocomposite consisting of self-assembling peptide nanofibers (organic phase) and tri-calcium phosphate-nano hydroxyapatite (mineral phase), was evaluated in rabbits.
Hemangiomas in the head and neck region, especially those that may impact the airway, require special attention perioperatively because of the potential for difficulties with airway management and bleeding control. This case report describes the management of a 31-year-old male with a large hemangioma of the tongue and pharynx undergoing surgical extraction of mandibular third molars under intubated general anesthesia. Despite taking precautions and avoiding traumatizing the hemangioma while securing the airway, massive bleeding occurred during the surgical extractions, which prompted emergent transfer for angiographic embolization and a stay in the intensive care unit until extubation.

BACKGROUND Brunneromas are among the rarest benign tumors of the upper gastrointestinal tract. They arise from the Brunner's glands and patients have a good prognosis if treated timely and radically. Because symptoms are rare, their diagnosis can be challenging, especially regarding the smaller ones.

Percutaneous renal puncture drainage is needed in patients with perirenal hematoma (PRH, renal around hematoma) with poor conservative treatment. Early and thorough removal of hematoma is closely related to the recovery of patients, but percutaneous renal drainage is not effective in some patients. The clinical data of 5 patients with PRH treated in the first affiliated Hospital of Chongqing Medical University from June 2020 to June 2024 were analyzed retrospectively.
