Objective: To determine whether it is possible to reduce the amount of pain and anxiety experienced during a vasectomy by use of two-dimensional (2D) video glasses or virtual reality (VR) glasses during the vasectomy.
Patients And Methods: A non-randomised controlled trial was performed between October 2017 and March 2018. A total of 176 patients were planned for a vasectomy in an outpatient setting and 141 of these patients were divided sequentially into three groups: Control, 2D video glasses and VR glasses. Follow-up lasted 7 days. One patient was lost to follow-up. The main outcomes were pain (visual analogue scale [VAS] score 0-10) and anxiety ((VAS score 0-10), and State-Trait Anxiety Inventory for Adults [STAI-AD] score 20-80) during the vasectomy. Data were compared using analysis of variance or chi-square measurements.
Results: No significant differences in pain were found (VAS score of 2 in all groups). The odds ratio (OR) and (95% confidence interval [CI]) in the 2D video glasses group was 1.15 (0.92-1.48) and in the VR group was 0.98 (0.76-1.26). Patients in the VR group experienced significantly more anxiety during the procedure (OR 1.40, 95% CI 1.07-1.85). Also, patients without prior hospitalisation reported significantly more pain than patients with one or more hospitalisations (OR 1.35, 95% CI 1.11-1.65).
Conclusions: The VR and 2D video glasses did not reduce pain or stress during the vasectomy. In the VR group, the anxiety levels during the procedure were even higher.

Background: Sometimes, the identification of ground-glass opacities (GGOs), small or deep pulmonary nodules can be difficult also in expert hands. Usually for these lesions pulmonary lobectomy is an overtreatment, so we developed a technique to identify easily these nodules. The objective of this research is to assess the effectiveness and safety of using preoperative cone beam computed tomography (CBCT) to guide the placement of micro-coils in the lung parenchyma near GGO and small lesions.

A 51-year-old man presented with chest tightness, exertional dyspnea, and occasional chest pain for 2 years. The patient visited his local hospital initially, and CT scan revealed a ground glass opacity (GGO) located in the right upper lobe (Fig 1A). He was diagnosed as having pulmonary infection and treated with levofloxacin for 12 days.

Premetastatic cancer cells often spread from the primary lesion through the lymphatic vasculature and, clinically, the presence or absence of lymph node metastases impacts treatment decisions. However, little is known about cancer progression via the lymphatic system or of the effect that the lymphatic environment has on cancer progression. This is due, in part, to the technical challenge of studying lymphatic vessels and collecting lymph fluid.

Article Synopsis
- The study evaluates the fracture strength of 1 mm-thick CAD/CAM occlusal veneers made from lithium disilicate (LD) and resin nanoceramics (RNC) to assess their viability in dental restoration.
- Using a novel testing protocol, the RNC group demonstrated a significantly higher load-bearing capacity compared to the LD group, indicating better durability under stress.
- Both materials experienced similar crack patterns during testing, emphasizing the importance of understanding mechanical properties for ensuring the longevity of dental restorations.
