Article Synopsis
- Traumatic optic neuropathy (TON) is a rare but serious condition leading to vision impairment, often resulting from facial trauma, emphasizing the need for effective diagnosis and treatment methods.
- A study analyzed four patients (average age 75) with midfacial fractures and TON, assessing their visual deficits and outcomes following navigation-assisted endoscopic trans-nasal optic nerve decompression (ETOND) treatment.
- Results showed that patients with pre-operative vision loss experienced post-operative improvement, with no complications arising from the procedures, highlighting the effectiveness of ETOND in managing TON.
Correction of coagulation is a crucial aspect of trauma care. While there are reports highlighting the effectiveness of fibrinogen concentrate in severe trauma cases with coagulopathic complications, literature on its use in pediatric cases remains limited. This paper discusses the case of a 5-year-old male presenting with a splenic injury and associated coagulopathy.

Due to the coronavirus disease 2019 (COVID-19) pandemic, a state of emergency was declared in Japan in March 2020. In this study, we aimed to examine the dynamics of patients with oral and maxillofacial trauma over a 12-years period using interrupted time-series (ITS) analysis.

Herein, we report a case of a patient treated with pembrolizumab who experienced a Grade 3 interrupted skin disorder. The patient is a 67-year-old female diagnosed with right maxillary gingival squamous cell carcinoma(cT4aN0M0, Stage ⅣA)and underwent partial right maxillectomy, right extended supra-omohyoid neck dissection, and maxillary reconstruction using a forearm flap.

- The superconductor-insulator transition (SIT) in two dimensions represents a key quantum phase transition with a quantum critical point at absolute zero temperature (T=0).
- In certain weakly disordered or crystalline thin films, an anomalous metallic (AM) state shows up between superconducting and insulating states, complicating the traditional QPT understanding of SIT.
- Measurements of the Nernst effect reveal a ghost-temperature line marking a thermal-to-quantum crossover, helping to locate the QCP within the AM state, thereby suggesting that the AM state is a critical extension of the SIT.
