Background: Inadequate preoperative management of chronic medications can place perioperative patients at risk and cause unnecessary delays in surgical procedures. This study aims to investigate the prevalence of chronic medication therapy problems (CMTPs) in hospitalized perioperative patients and assess the relevance of pharmacists' interventions.

Methods: We conducted a retrospective study of pharmacist-led preoperative management of chronic medications in hospitalized adult patients from November 2018 to April 2019.

Purpose: To assess the false-positive and false-negative MRI results in evaluating the extent of tongue squamous cell carcinoma.

Methods: A prospective cohort series of 165 patients was enrolled to assess the false-positive and false-negative MRI results in evaluating the extent of tongue squamous cell carcinoma by comparing intraoperative tumor profile images and postoperative pathological sections. The differences between two-dimensional tumor margins were analyzed using Mimics 15.

Article Synopsis
  • * It included 150 patients and found that the average measurement differences were 2.32 mm between MRI and post-surgery reports, and 1.64 mm between MRI and surgical specimens, suggesting variability in measurement methods.
  • * The research indicated that clinicians should be careful when using MRI to gauge the depth of invasion, particularly noting a false-positive depth of 2.3 mm, as well as specific depth thresholds (8 mm for nodal metastasis, 11 mm for overall and disease-specific survival) for better patient prognosis.

Background: Approximately 60-80% of patients with advanced head and neck squamous cell carcinoma (HNSCC) die within five years after diagnosis. Cisplatin-based chemotherapy is the most commonly used palliative treatment for these patients. To evaluate the prognostic value of X-linked inhibitor of apoptosis (XIAP) level as a potential biomarker in these patients, we investigated the relationship between XIAP expression and cisplatin response of these patients and their prognosis.

Discomfort of right eye and right maxilla region occurred after a dental implant placement in a patient who surfered stabilized osteofibrous dysplasia (OFD) of sphenoid sinus. In this article, the case was discussed and the relevant literature was reviewed. The possible causes of eye and maxilla discomfort may be associated with OFD, hyper allergic response to implant material and surgical trauma, and psychical factors as well.

As one of the most common malignancies of the salivary glands, mucoepidermoid carcinoma had a rare frequency in mandible. A case of central mucoepidermoid carcinoma of the mandible was reported and relevant literatures were reviewed. The possible etiology, clinical symptom, radiology, histopathology, diagnosis and treatment of central mucoepidermoid carcinoma were discussed.
