Purpose: This study evaluated the effectiveness of a protocol using platelet-rich plasma (PRP) to prevent bleeding after dental extraction in patients treated with anticoagulant oral therapy.
Materials And Methods: Forty patients with mechanical heart-value replacement who were treated with anticoagulant oral therapy were selected for the study. Each patient was treated with PRP gel placed into residual alveolar bone after extraction without heparin administration after suspension of oral anticoagulant drugs (36 hours).
Results: Only 2 patients reported hemorrhagic complications (5%). Sixteen patients (40%) had mild bleeding that was easy to control with hemostatic topical agents; this mild bleeding terminated completely 1 to 3 days after the surgical procedures. The remaining 22 patients (55%) presented with adequate hemostasis.
Conclusions: Oral surgery in heart surgical patients under oral anticoagulant therapy may be facilitated with PRP gel. Its use is an advanced and safe procedure. This biological and therapeutical improvement can simplify systemic management and help avoid hemorrhagic and/or thromboembolic complications.

Background: Nearly 25% of opioid-related deaths are from prescribed opioids, and the exacerbation of the opioid epidemic by the coronavirus disease 2019 (COVID-19) pandemic underscores the urgent need to address superfluous prescribing. Therefore, we sought to align local opioid prescribing practices with national guidelines in postoperative non-metastatic breast cancer patients.
Methods: A single-institution analysis included non-metastatic breast surgery patients treated between April 2020 and July 2021.

Myofascial pain is one of the common symptoms in patients with temporomandibular joint disorders (TMD). Occlusal splint (OS) and masticatory muscle trigger point (TP) local injections are primary treatment options. We aimed to investigate the effects of these treatments using clinical and elastography measures.

Trigeminal neuralgia (TN) usually affects the maxillary and mandibular branches of the fifth cranial nerve. Although the condition is primarily unilateral, few cases of bilateral manifestation have been reported. TN is uncommon; however, it significantly affects patients' quality of life because the neuropathic pain worsens over time.

Background: Tissue metabolomics analysis, alongside genomics and proteomics, offers crucial insights into the regulatory mechanisms of tumorigenesis. To enhance metabolite detection sensitivity, chemical isotope labeling (CIL) techniques, such as dansylation, have been developed to improve metabolite separation and ionization in mass spectrometry (MS). However, the dissolution of hydrophobic derivatized metabolites in solvents with high acetonitrile content limits the use of liquid chromatography (LC) systems with small-volume reversed-phase (RP) columns.
