It is a common practice nowadays to plan needle access pathways to the volumetric organs before performing surgeries. An enormous amount of needle access planning systems has been proposed in recent years. Recent works mainly focus on the system usability or target accessibility. Visualization of the planned access pathways has drawn little attention and its effect on insertion quality is left unattended. We aim to address this problem by introducing an all-round evaluation framework that links up with human motions and computer graphics. Our evaluation framework provides an objective and quantitative analysis of the illustrativeness of the needle access pathway visualization techniques to an extent of five degrees of freedom. Our experimental results show that the visualization method adopted greatly influences insertion accuracy. Based on this finding, we propose a new visualization technique that intuitively conveys placement and orientation information. We also show that our method better conveys pathway orientation and thus enables a higher quality of insertion.

Purpose: Carotid-cavernous fistulas (CCFs) are abnormal connections between the carotid artery and cavernous sinus, often causing ocular symptoms like chemosis, proptosis, and diplopia. Endovascular embolization is the preferred treatment, typically performed via the transfemoral transvenous route through the inferior petrosal sinus (IPS). However, we present a case and a systematic review of indirect CCF treated through deep orbital puncture of the superior ophthalmic vein (SOV) for embolization.

: Hydrogen gas (H) has been shown to be effective in the treatment of various clinical conditions, from acute illnesses to chronic illnesses. However, its clinical indications and the corresponding appropriate hydrogen delivery methods have yet to be determined. This is due to the fact that the pharmacokinetics and pharmacodynamics of hydrogen in each delivery method have not been experimentally proven.

Objectives: The aim of this study was to review the most effective topical anesthetic methods for reducing pain/discomfort prior to dental local anesthetic needle puncture for dental procedures in children and adolescents.
Methods: A scoping review was conducted. Individual search strategies were developed for each of the bibliographic databases (Cochrane, Embase, LILACS, LIVIVO, Pubmed, Scopus, PsyINFO, Web of Science), and in the gray literature (Google Scholar, Open Gray), comprehensively, without restrictions on language, publication data, or level of socioeconomic development of the country in which the study was conducted.

Primary hyperparathyroidism (PHPT) is a prevalent clinical condition characterized by an inappropriate secretion of parathyroid hormone (PTH). It is most often caused by one or more parathyroid adenomas, which can, in rare cases, be ectopically located. Ectopic adenomas can pose a diagnostic challenge, lead to treatment delay, and be a common cause of recurrent hypercalcemia after parathyroidectomy.

Background: The nursing profession plays a crucial role in the quality of healthcare services. While nurses face occupational injury challenges globally, mental workload, which is often overlooked, plays a significant role in these injuries. Understanding nurses' coping strategies can help develop effective interventions.
