Objectives:
Traumatic optic neuropathy (TON), a relatively rare condition, can cause visual functional impairment and permanent functional damage.Surgeons should be familiar with its diagnostic criteria and treatment to effectively manage cases of facial trauma with TON. We investigated the feasibility of navigation-assisted endoscopic trans-nasal optic nerve decompression (ETOND) to treat TON in maxillofacial trauma patients.
Patients and Methods:
We retrospectively analyzed data from the clinical investigation of four consecutive patients, two males and two females with an average age of 75 years, with midfacial fractures and TON between April 2021 and September 2023. All patients had swelling and subcutaneous periorbital hemorrhage accompanied by optic nerve canal and zygomaticomaxillary complex fractures on the affected side. Three patients had lacerations on the lateral eyebrow or upper eyelid. All patients were evaluated by an ophthalmologist for visual impairment; two patients could see hand motion at a 30 cm distance, one patient could perceive light, and one did not have any loss of visual acuity. Among the four patients, three had visual impairment immediately after the injury, and one showed delayed impairment.
Results:
The patients were treated with navigation-assisted ETOND conducted by an endoscopic rhinologist. Three of the ETONDs were performed along with open reduction and internal fixation (ORIF); the other ETOND was delayed. Orbital reconstruction was performed in three patients. Steroid therapy was administered to two patients, one pre-operatively and one post-operatively. The two patients with pre-operative vision loss showed improved visual acuity post-operatively, and the two patients with no pre-operative visual impairment had no vision loss associated with ORIF for their midfacial fractures. No patient had post-operative complications.
Conclusion
Navigation-assisted ETOND can be performed easily by endoscopic rhinologists; and prompt examination, diagnosis, and treatment are important in patients with facial trauma and TON.

Clinical Endoscopy 2021;54(3):363-370
Background/Aims:
Probe-based confocal laser endomicroscopy (pCLE) requires the administration of intravenous (IV) fluorescein. This study aimed to determine the optimal dose of IV fluorescein for both upper and lower gastrointestinal (GI) tract pCLE.
Methods:
Patients 20 to 79 years old with gastric high-grade dysplasia (HGD) or colorectal neoplasms (CRNs) were enrolled in the study. The dose de-escalation method was employed with five levels. The primary endpoint of the study was the determination of the optimal dose of IV fluorescein for pCLE of the GI tract. The reduced dose was determined based on off-line reviews by three endoscopists. An insufficient dose of fluorescein was defined as the dose of fluorescein with which the pCLE images were not deemed to be visible. If all three endoscopists determined that the tissue structure was visible, the doses were de-escalated.
Results:
A total of 12 patients with gastric HGD and 12 patients with CRNs were enrolled in the study. Doses were de-escalated to 0.5 mg/kg of fluorescein for both non-neoplastic duodenal and colorectal mucosa. All gastric HGD or CRNs were visible with pCLE with IV fluorescein at 0.5 mg/kg.
Conclusions
In the present study, pCLE with IV fluorescein 0.5 mg/kg was adequate to visualize the magnified structure of both the upper and lower GI tract.

Objective: Soon after two massive earthquakes in Kumamoto, Japan, on April 14 and 16, 2016, the Shirakawasuigen pharmacy located in the Minamiaso village received prescriptions for disaster medications. Since prescriptions for disaster medications are typically used at temporary emergency shelters, pharmacies usually do not receive requests for them. On checking the content of these prescriptions, we found numerous prescription errors and queries. This study aimed to assess issues with dispensing medications after disasters.Methods: We reviewed all disaster medication prescriptions received by the pharmacy from April 20 to May 28, 2016 and the medication histories of these patients. We confirmed each patient’s data and medical and medication histories. Furthermore, we classified disaster prescription errors and queries into five categories according to their content and summed them in each category.Results: We obtained patients’ medical and medication histories from 100 (77.5%) of the 129 prescriptions received. Of the 129 prescriptions, a total of 158 prescription errors and queries pertaining to 96 (74.4%) prescriptions were confirmed: 88 (55.7%) for unclear medication usage and dosages, 22 (13.9%) for incorrect medication names, 34 (21.5%) for pharmaceutical queries, 8 (5.1%) for exceeding fixed prescription days (within seven days), and 6 (3.8%) for other issues.Conclusion: Nearly 80% of the prescriptions for disaster medications had prescription errors and queries. Therefore, we evaluated that the prescription’s format and entry method can be improved. Furthermore, to ensure a smooth drug supply and to reduce prescription entry deficiencies and formal prescription queries, pharmacists need to effectively manage disaster prescriptions.

This systematic review aimed to assess the efficacy of the current approach to tissue traction during the endoscopic submucosal dissection (ESD) of superficial esophageal cancer, early gastric cancer, and colorectal neoplasms.We performed a systematic electronic literature search of articles published in PubMed and selected comparative studies to investigate the treatment outcomes of tractionassisted versus conventional ESD. Using the keywords, we retrieved 381 articles, including five eligible articles on the esophagus, 13 on the stomach, and 12 on the colorectum. A total of seven randomized controlled tri-als and 23 retrospective studies were identified. Clip line traction and submucosal tunneling were effective in re-ducing the procedural time during esophageal ESD. The efficacy of traction methods in gastric ESD varied in terms of the devices and strategies used depending on the le-sion location and degree of submucosal fibrosis. Several prospective and retrospective studies utilized traction de-vices without the need to reinsert the colonoscope. When pocket creation is included, the traction devices and methods effectively shorten the procedural time during colorectal ESD. Although the efficacy is dependent on the organ and tumor locations, several traction techniques have been demonstrated to be efficacious in facilitating ESD by maintaining satisfactory traction during dissection.

Treating a thoracic aortic aneurysm (TAA) after coronary artery bypass graft (CABG) surgery requires an appropriate surgical procedure to preserve the functional graft. We present a case of hybrid procedure of thoracic endovascular aortic repair combined with a redo off-pump CABG via median sternotomy. The patient was a 76-year-old man with a history of CABG and abdominal aortic replacement in a different country. Chest computed tomography revealed a saccular-shaped aortic aneurysm in the distal aortic arch with diameter of 5.6 cm. Coronary angiography revealed theLIMA graft was patent but anastomosed to the diagonal branch and the left anterior descending artery (LAD) was totally occluded and was opacified through the right coronary artery. Significant ischemic change in the anteroseptal wall suggested a requirement of surgical revascularization of LAD. The chest was opened via re-midsternotomy. Then the 3 arch vessels were reconstructed with a trifurcated artificial graft attached to the ascending aorta and coronary artery bypass grafting was performed on the beating heart. Finally, the aneurysm was excluded by introducing a stent graft through the graft to zone 0. The patient's postoperative course was uneventful and he was discharged on postoperative day 16. A hybrid procedure via median sternotomy was useful in the surgery for TAA with the functional LIMA after CABG.

Most mediastinal abscesses result from infections after thoracotomy, esophageal perforation or pene- trating chest trauma. This disease is rarely caused by closed blunt chest trauma. All previously reported such cases after closed blunt chest trauma presented with hematoma and sternal osteomyelitis resulting from sternal fracture. Here we report a 15-year-old sumo wrestler who presented with an anterior mediastinal abscess without any mediastinal fracture. The mediastinal abscess resulted from the hematogenous spread of Staphylococcus aureus to a hematoma that might have been caused by a closed blunt chest trauma incurred during sumo wrestling exercises.

[Purpose]The purpose of this paper is to examine whether or not the Press Tack Needle (PTN) treatment enhances the recovery process from muscle fatigue which assists in the therapeutic exercise rehabilitation process. By using the PTN, this paper investigates the recovery effect of the fatigued muscle. Randomized controlled trials were used to compare outcomes.
[Method]Twenty-nine healthy male adults were chosen as subjects. However, crossover study was used to compare the PTN group and the sham group. After two sets of arm curl exercises with isotonic contraction at 10%weight of maximum voluntary contraction, the decrease percentage of exercise repetition was calculated. A PTN or sham was inserted at the posterior cervical region using the double masking method. After the intervention of the PTN or sham needle, the subjects were asked which intervention was inserted into them. A Kappa statistics value was used to evaluate the validity of the sham group and a Visual Analog Scale (VAS) was used to determine the upper arm fatigue.
[Result]The Kappa statistic value was 0.17. The decrease percentage of the exercise repetition of the PTN group was 35.4±20.1%, and of the sham group was 45.1±11.1%. The PTN group indicated a significantly smaller percentage than the sham group (p<0.01). Both groups showed no difference in Upper arm fatigue.
[Conclusion]The PTN seems to help in recovery from muscle fatigue. It is thought that by inserting the PTN, somato-automomic reflex was induced to promote the increase of blood flow in to the muscle. Faster recovery of physical function of the patient can be possible as well as the improvement of QOL. In conclusion, this investigation showed that the PTN treatment method can be useful in assisting in therapeutic exercise rehabilitation.
