Introduction: One of the advantages of cone-beam computed tomography (CBCT) is the possibility of obtaining images of conventional lateral cephalograms derived from partial or complete reconstruction of facial images.
Objective: This study aimed at comparing full face, right and left hemifacial CBCT cephalograms of orthodontic patients without clinical facial asymmetry.
Methods: The sample comprised nine clinically symmetrical patients who had pretreatment full face CBCT. The CBCTs were reconstructed so as to obtain full face, right and left hemifacial cephalograms. Two observers, at two different times, obtained linear and angular measurements for the images using Dolphin 3D software. Dependent and independent t-tests were used to assess the reproducibility of measurements. Analysis of Variance and Kruskal-Wallis tests were used to compare the variables obtained in the CBCT derived cephalometric views.
Results: There was good reproducibility for CBCT scans and no statistically significant differences between measurements of full face, right and left hemifacial CBCT scans.
Conclusions: Cephalometric measurements in full face, right and left hemifacial CBCT scans in clinically symmetrical patients are similar.

Model organisms are vital for biomedical research and drug testing but face high costs, complexity, and ethical issues. While newer techniques like organoids and assembloids have shown improvements, they still remain inadequate in addressing all research needs. In this study, we present a new method for maintaining the prostate gland of the earthworm, Eudrilus eugeniae ex vivo and examine its potential for regeneration and drug screening.

Various studies have shown that individuals with bullous pemphigoid (BP) are more likely to develop venous thromboembolism (VTE). However, it is important to acknowledge that these studies primarily focused on individuals in Western nations, which restricts their generalization to a wider demographic. The present systematic review aims to assess the cumulative risk of VTE in individuals with BP compared to healthy individuals.

Objectives To develop a value set for the EQ-5D-5L based on preferences of the general adult population of the United Arab Emirates (UAE). Methods The study followed the EuroQol EQ-5D-5L Valuation protocol and involved conducting interviewer-administered face-to-face or online interviews in Arabic or English, using the EuroQol Valuation Technology (EQ-VT) with a sample of 1005 adults representing the UAE general population. Sample recruitment involved a two-stage quota sampling strategy across the seven Emirates of the UAE, ensuring representation of nationals and expatriates.

Introduction: In facial cosmetic surgery, injectable liquid silicone has been used to augment the cheek and the lips and to camouflage facial wrinkles. However, complications started to arise in 1964 as postoperative silicone granuloma formation. The purpose of this study is to introduce our experience in facial reconstruction after injectable silicon oil with a sequential 3-step approach: transoral surgical excision, full-face fat grafting, and hyaluronic acid filler.
