Impact of Direct Observation on Hand Hygiene Compliance in a Dental University Hospital: A Retrospective Cohort Study.

Introduction Hand hygiene is crucial for preventing healthcare-associated infections in dental settings. Despite its importance, the hand hygiene compliance rates remain unclear, particularly in dental university hospitals where teaching, research, and clinical practice intersect. This study aimed to establish a baseline of hand hygiene compliance rates in a dental university hospital, evaluate the effectiveness of direct observation in improving compliance, and compare practices among different categories of healthcare workers.

Preventable Sternocleidomastoid Muscular Atrophy after Neck Dissection.

Background: Modified radical neck dissection (mRND) [preserving the sternocleidomastoid muscle (SCM) and the spinal accessory nerve] and supraomohyoid neck dissection have become common surgical procedures for treating head and neck cancer. Postoperative severe asymmetry of the neck and severe atrophy of the SCM, however, have been demonstrated.

Methods: Using computed tomographic images, cross-sectional areas of the SCMs were measured in 99 patients with carcinoma of the oral cavity who underwent unilateral mRND or supraomohyoid neck dissection.

Risk factors for distant metastasis in squamous cell carcinoma of the oral cavity.

Purpose: This study aimed to identify risk factors for distant metastasis (DM) in patients with squamous cell carcinoma of the oral cavity.

Materials And Methods: A retrospective analysis of 516 patients with squamous cell carcinoma of the oral cavity from 1986 through 2009 was performed. DM was classified as 2 types based on whether patients had locoregional failure (LRF).

Decision analysis and treatment threshold in a management for the N0 neck of the oral cavity carcinoma.

The optimal method of management of clinical N0 neck in squamous cell carcinoma of the oral cavity remains controversial. We used decision analysis to determine the current optimal strategy in comparison with observation of the neck and elective neck dissection. A total of 165 previously untreated patients with N0 classification were investigated.
