For many patients with trigeminal neuralgia, oral administration of carbamazepine is highly effective. Micro decompression surgery (Jannetta's operation) is also considered a fundamental treatment. However, there are patients who do not respond to carbamazepine and who hesitate to have surgery. Here, we report 14 cases whose pain was relieved solely by Kampo (7 cases) or by a combination of Kampo and carbamazepine (7 cases). The Kampo formulations used were Goshuyu-to (2 cases), Gorei-san (9 cases), Saiko-keishi-to (1 case), Toki-shigyaku-ka-goshuyu-shokyo-to (1 case) or Mao-bushi-saishin-to (1 case), depending on the “Zheng” of each patient. In trigeminal neuralgia, the nerve root is compressed or adhered to surrounding vessels, such as the superior cerebellar artery. It is highly possible that localized edema at the point of compression is responsible for the pain. The diuretic action of the Kampo may diminish the localized edema around the trigeminal nerve root.

Purpose: The impact of postoperative nutritional status on clinical outcomes and biomechanics following total knee arthroplasty remains largely unknown. This study aimed to assess this question using the prognostic nutritional index to evaluate the nutritional status of orthopedic participants. Methods: Patients with knee osteoarthritis who underwent total knee arthroplasty (n=49) in Japan were divided into two groups based on their 1-week postoperative prognostic nutritional index. Group L patients had a prognostic nutritional index <40, whereas Group H comprised patients with a prognostic nutritional index ≥40. Postoperative improvements in Knee Injury and Osteoarthritis Outcome Score were evaluated. The patients performed squats under single-fluoroscopic surveillance in the sagittal plane for biomechanical evaluation. A two-dimensional/three-dimensional registration technique was employed to measure the tibiofemoral kinematics. The axial rotation of the femoral component relative to the tibial component and the anteroposterior translation of the medial and lateral femorotibial contact points were measured. Results: Group H showed significantly higher pain scores than Group L at 12 and 36 months postoperatively and a significantly higher symptom score at 36 months postoperatively. The kinematic comparison revealed that the axial external rotation in Group L was larger than that in Group H from 70° to 80° with flexion. Moreover, in the medial anteroposterior translation, Group L was more anteriorly located than Group H, with flexion beyond 30°. Conclusion The results suggest that a high postoperative nutritional status significantly improved pain and other symptoms and was associated with better knee biomechanics following total knee arthroplasty.

Background/Aims: The adenoma detection rate (ADR) of screening colonoscopies performed by trainees is often lower than that of colonoscopies performed by experts. The effcacy of cap-assisted colonoscopy (CAC) in adenoma detection is well documented, especially that of CACs performed by trainees. Endocuff, a new endoscopic cap, is reportedly useful for adenoma detection; however, no trials have compared the effcacy of Endocuff-assisted colonoscopy (EAC) and CAC conducted by trainees. Therefore, the present study retrospectively compared the effcacy between EAC and CAC in trainees. Methods: This was a single-center, retrospective study involving 305 patients who underwent either EAC or CAC performed by three trainees between January and December 2018. We evaluated the ADR, mean number of adenomas detected per patient (MAP), cecal intubation rate, cecal intubation time, and occurrence of complications between the EAC and CAC groups. Results: The ADR was significantly higher in the EAC group than in the CAC group (54.3% vs. 37.3%, p=0.019), as was the MAP (1.36 vs. 0.74, p=0.003). No significant differences were found between the groups with respect to the cecal intubation rate or cecal intubation time. No major complications occurred in either group. Conclusions Our results suggest that EAC exhibits increased ADR and MAP compared to CAC when performed by trainees.
