Severe corneal manifestations of graft-versus-host disease: experience of a tertiary referral center.

Purpose: Graft-versus-host disease (GVHD) is a common complication after allogeneic hematopoietic stem cell transplantation (allo-HSCT). GVHD may affect several organs, including ocular manifestations, ranging from dry eye syndrome to sight-threatening corneal ulceration or perforation. Limited information is available about characteristics and treatments of ocular GVHD and its relation to general prognosis.

Outcomes of Total Thyroidectomy in Large Goiters With Retrosternal Extension and Tracheal Compression: A Multivariate Analysis.

Introduction: Large retrosternal goiters often cause tracheal compression and deviation, leading to respiratory symptoms and complicating surgical treatment. Total thyroidectomy is the treatment of choice though it carries a risk of complications due to the altered anatomy and its proximity to vital structures. This study examines the outcomes of total thyroidectomy in patients with retrosternal goiters and assesses the impact of tracheal compression on clinical results.

Comparative evaluation of the influence of the palatal root length on the efficacy of maxillary buccal infiltration by open and closed mouth technique: a randomized control trial.

Background: Maxillary molars are commonly anesthetized via buccal infiltration. A patient's mouth opening during maxillary buccal infiltration can influence dental treatment. Hence, this study aimed to evaluate and compare the influence of palatal root length on the efficacy of 2% lidocaine in 1:80000 adrenaline for maxillary buccal infiltration (MBI) between the open- and closed-mouth techniques.

Comparative Evaluation of the Effect of Different Irrigation Regimens With and Without Ultrasonic Activation on Root Dentin Microhardness: An In Vitro Study.

Background The structural properties of dentin, including its microhardness, can be affected by exposure to endodontic irrigating solutions and ultrasonic activation. Aim The current study aimed to assess the effect of three different irrigation regimens, with and without ultrasonic activation, on the microhardness of the dentin. Methodology The research was conducted on 120 mandibular premolars randomly divided into four groups (n=30) based on the irrigation regimen, with each group further divided into two subgroups (n=15).
