Histopathological Comparison of Various Tongue Base Reduction Processes.

Background And Aim: 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.

Selective Deep-Lobe Parotidectomy for Benign Parotid Gland Tumors.

Background: 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.

Aim: To evaluate the surgical outcomes and oncological safety of selective deep-lobe parotidectomy (SDLP) in patients with benign lesions located in the deep lobe of the parotid gland.

Anemia detection and quantification in contrast-enhanced CT scans on a novel photon-counting detector CT: A prospective proof-of-concept study.

Purpose: To correlate CT values of the blood pool on VNC series with serum hemoglobin values for the detection of anemia in oncologic patients undergoing contrast-enhanced PCD-CT scans.

Methods: This prospective study (NCT04989192) included consecutive oncologic patients undergoing contrast-enhanced CT on a novel PCD-CT system between 08/2021 and 01/2022. The interval between complete blood count (CBC) and CT scan acquisition had to be no more than seven days.

Clinicopathologic significance of human epidermal growth factor receptor 2 expression and gene amplification in gastric carcinoma.

Aim: This study is aimed at determining the human epidermal growth factor receptor-2 (HER-2) gene status in gastric cancers using immunohistochemistry (IHC) and silver DNA in situ hybridization (SISH) technique and investigating the relationship between HER-2 status and clinicopathological variables.

Materials And Methods: We examined 104 gastric carcinoma cases with gastrectomy specimens. The age, sex, histopathological tumor type, tumor differentiation, tumor localization, tumor size, invasion depth, lymph node metastasis status, HER-2 IHC evaluation results, and SISH evaluation results of the cases were recorded.
