Multicenter Study
Influence of living environments and working status on low back pain for survivors of the Great East Japan Earthquake.
The Great East Japan Earthquake and devastating Tsunami caused irreparable damage on the northeastern coast of Japan. This study aimed to examine the influencing factors of "Living environment" and "Working status" on low back pain for the survivors of the earthquake evaluated by a self-report questionnaire. ⋯ Though living environment has little effect, "Decrease in income" and "The same occupation as before the earthquake" have strong influences on low back pain.

Tranexamic acid (TXA) has proven its efficacy in reducing blood loss and the need for blood transfusions in patients who have undergone a total knee arthroplasty (TKA) surgical procedure. However, no study has investigated the benefits of TXA in unicompartmental knee arthroplasty (UKA), especially, in regard to minimally invasive surgery (MIS) UKA. The purpose of this study is to attempt to prove the benefits of TXA and to identify the risks for blood loss and need for blood transfusions in MIS UKA. ⋯ Based on the study results, we suggest that the use of TXA for patients who undergo MIS UKA do not show benefits in the reduction of blood loss. There were no predictors for the risk of blood loss determined in MIS UKA.

In non-Western countries including Japan, activities requiring deep flexion of the hip joint, such as seiza (kneeling with calves tucked under the thighs and buttocks resting on the heels) and using squat toilets are commonly practiced. The purpose of this study was to assess longitudinal changes in traditional health-related quality of life measures and measures of physical functions associated with lifestyle for Japanese patients pre-surgery and after total hip arthroplasty. ⋯ The rate of improvement in QOL requiring deep flexion of the hip joint was much slower than that in QOL related to Western lifestyle. Our study suggests a need for lifestyle modification for THA patients in the other countries where kneeling and squatting are commonly performed.

The Japanese Orthopaedic Association Cervical Myelopathy Evaluation Questionnaire (JOACMEQ) was developed to resolve problems associated with the original evaluation of cervical myelopathic patients. The aim of this study was to translate the JOACMEQ into Thai as per international recommendations, and to test its reliability and validity in the Thai context ⋯ The Thai version of the JOACMEQ had satisfactory internal consistency and test-retest reliability: it also had good construct validity. It can therefore be used as a reliable tool for assessing quality of life for cervical myelopathy patients in Thailand.

This study retrospectively compared the clinical benefits of periarticular multimodal drug injection (PMDI) and continuous femoral nerve block (CFNB) after total knee arthroplasty (TKA). ⋯ Our results indicate that PMDI induced earlier functional recovery after TKA than CFNB, partially via its analgesic effect.
