Deep-lobe tumors have been shown to possess a significantly thicker capsule with less tumor penetration compared to superficial tumors. Thus, more conservative surgical approaches, rather than aggressive methods, have been proposed for treating benign deep-lobe tumors of the parotid gland. ⋯ SDLP may facilitate the safe surgical removal of benign lesions located in the deep lobe of the parotid gland, with oncological safety, reduced complication rates, and improved cosmetic outcomes.

The mentioned advantages of bulk-fill composite resin and high-viscosity glass ionomer restorative materials have increased their use in restorative dentistry in recent years; accordingly, the bonding of these materials to dental tissues and their mechanical properties have become more important. ⋯ It can be concluded that preheating before application may increase the shear bond strength of reinforced high-viscosity glass ionomer.

Reverse shoulder arthroplasty (RSA) is used commonly for a wide range of indications. The complications after the total shoulder replacements have been reported to be related with the prosthesis design. The type of the humeral stem is a consideration to reduce complication. Radiographic changes are seen at a high rate with new-generation press-fit stems. ⋯ The increased radiographic stress shielding adaptation leading to humeral osteolysis was found to have a negative effect on the functional results with the press-fit technique irrespective of stem design.

Colorectal carcinoma (CRC) is the most common gastrointestinal malignancy in Nigeria with a dismal 5-year survival rate. Interactions between the CD8+ T-lymphocytes and the immune checkpoints such as cytotoxic T-lymphocyte antigen-4 (CTLA-4) and programmed death-ligand 1 (PD-L1) expressions are important. Novel antibodies have been developed against these immune checkpoints and have been found to improve clinical outcome in many solid organ malignancies. ⋯ PD-L1 expression in CRC was low (5.6%) and showed strong associations with higher tumor grades (P < 0.013), right-sided tumors (P < 0.002), and rectal cancer. There was no association with age, tumor stage, and lymph node status.

Comparative Study
Histopathological Comparison of Various Tongue Base Reduction Processes.
Tongue base reduction surgery is the only minimally invasive technique that can be performed under local anesthesia as an outpatient procedure, especially to treat obstructive sleep apnea caused by hypopharyngeal obstruction. Studies reported that various devices could be used for tongue base reduction, but comparisons of these methods are limited in the literature. Our study aimed to compare the histological effects of tongue base reduction methods performed with the Celon radiofrequency, monopolar cautery, Coblator, and Sutter devices on the tissue. ⋯ Although we observed that all the methods used were safe, the method that produced the most fibrosis and tissue reduction was the Sutter method.
