As regards to low back pain of agricultural worker, there are many problems still as to a syndrom of “Nofusho” in rural medicine, a disease in ocupational medicine and clinic of orthopedic.
Agricultural worker who complained of low back pain varies with their country and farm products, and it tend to increase with adding to their age. Further, the female rate of low back pain showed slightly high tendency than the made rate, 8.5-12.5 % of male, 6.5-13.4 % of female always complained of low back pain.
According to the findings of roentogenographic examination of back bone, the deformed vertebrae was found clearly, especially, low back pain caused by a trauma of soft tissue and iscogenic pain showed in farmers. Therefor, it is necessary to be improved working posture and condition.
In comparrison with non-farmer, it is located in order of truck drivers. bus drivers and repairmen.

RevMate®is one of risk minimization activities in Japanese RMPs of Revlimd®and Pomalyst®, of which indications are hematological malignancy including multiple myeloma. This is a proper management procedure approved by Japanese health authorities in order to prevent exposure to pregnant women because these agents are derivatives of thalidomide. RevMate® was revised in 2015 after the discussion in MHLW's Taskforce and its operation started from April 2016. Due to this revision of version 5.0, the manufacture no longer receives the patient name, and this and other information must be managed by the hospital. In addition, with regard to the same objective in the format used in the management procedure（TERMS®）of thalidomide drug products, unification was attempted concerning the name of the format andthe notation of confirmation items. Physician becomes to make judgment to omit explanation of some RevMate® requirements based on the patient's level of their understandings to RevMate®. Periodical survey sheet regarding compliance with RevMate® requirement filled by a patient is to be submitted directly to a physician on his/her visit instead of sending it to the manufacturer by mail under previous procedures. A representative person of the manufacture is required to visit the hospital periodically and confirm filing condition of the survey sheets and compliance check lists of RevMate® for every prescription as well appropriately at the hospital. Furthermore, RevMate® was revised to add clear role description of relevant pharmacists and nurses for in-patients and its strict drug-handling procedures at bedside as version 5.1, as we received four reports from hospitals of medication error of our drug to the another patient in the hospital within 2016. After getting approval of additional indications for Revlimid® from March 2017, RevMate® of version 5.2 started. In the view of implement RevMate® as strict “risk minimization activities” to prevent pregnant women from exposure, we will continue to solve each problem recognized from the actual operation, constantly keep basics in mind by providing necessary training to our employees about thalidomide drug problem etc. In addition, we appreciate the understanding and support from the patient, patient family, Healthcare Professional, etc. involved in this procedure without incompleteness as well as non-compliance with procedures caused by habituation. Including all these, we consider it is important to endeavor as a manufacture continuously in the future.

In Korea, mass mortality of Quercus mongolica trees has become obvious since 2004. Raffaelea quercus-mongolicae is believed to be a causal fungus contributing the mortality. To evaluate the pathogenicity of the fungus to the trees, the fungus was multiple- and single-inoculated to the seedlings and twigs of the mature trees, respectively. In both the inoculations, the fungus was reisolated from more than 50% of inoculated twigs and seedlings. In the single inoculations, proportions of the transverse area of non-conductive sapwood at inoculation points and vertical lengths of discoloration expanded from the points were significantly different between the inoculation treatment and the control. In the multiple inoculations, no mortality was confirmed among the seedlings examined. These results showed that R. quercus-mongolicae can colonize sapwood, contribute to sapwood discoloration and disrupt sap flows around inoculation sites of Q. mongolica, although the pathogenicity of the fungus was not proven.

Methods: We investigated patients who underwent surgical intervention for LL-OVC (L3, L4, and/or L5) with symptomatic foraminal and/or central stenosis from eight spine centers. Only patients with a minimum follow-up duration of 1 year were included. We developed new criteria to grade vertebral collapse severity (grade 1, 0%–25%; grade 2, 25%–50%; grade 3, 50%–75%; and grade 4, 75%–100%). The clinical features and outcomes were compared based on the collapse grade and surgical procedures performed (i.e., decompression alone, posterior lateral fusion [PLF], lateral interbody fusion [LIF], posterior/transforaminal interbody fusion [PLIF/TLIF], or vertebral column resection [VCR]). Results: In this study, 59 patients (average age, 77.4 years) were included. The average follow-up period was 24.6 months. The clinical outcome score (Japanese Orthopaedic Association score) was more favorable in the LIF and PLIF/TLIF groups than in the decompression alone, PLF, and VCR groups. The use of VCR was associated with a high rate of revision surgery (57.1%). No significant difference in clinical outcomes was observed between the collapse grades; however, grade 4 collapse was associated with a high rate of revision surgery (40.0%). Conclusions When treating LL-OVC, appropriate instrumented reconstruction with rigid intervertebral stability is necessary. According to our newly developed criteria, LIF may be a surgical option for any collapse grade. The use of VCR for grade 4 collapse is associated with a high rate of revision.

A 76-year-old female was admitted with complaints of dyspnea on exertion and lower leg edema. She had undergone an aortic valve replacement thirty-nine years before and a redo aortic valve replacement and mitral valve replacement twenty-eight years before. She also had hemolytic anemia with jaundice. Echocardiography showed severe paravalvular leakage in the aortic and mitral valves, and a blood flow in the aortic annulus that flows from the aortic side into the left atrium. We diagnosed heart failure and hemolytic anemia due to paravalvular leakage and decided to perform a double-valve replacement for the third time. On operation, after removing the aortic valve through aortotomy, aorto- mitral fibrous continuity was extensively calcified and perforated, and its strength was not enough to sew the prosthetic valve to it. Therefore, we decided to perform the Commando procedure. Aortotomy was extended between the noncoronary aortic sinus and the left coronary aortic sinus until it reached the dome of the left atrium. After the prosthetic mitral valve was excised, annuloplasty of the posterior mitral annulus was performed using a bovine pericardial patch, and the new prosthesis mitral valve was implanted. The anterior part of the annulus corresponding to the aorto-mitral fibrous continuity was reconstructed by sewing the base of a two-tongued triangular bovine pericardial patch to the sewing cuff of the mitral prosthesis. After closing the left atrial ceiling with the posterior patch, the aortic prosthesis was secured to the aortic annulus and the pericardial patch. The anterior patch was used to close the right side of the aortotomy. The postoperative course was uneventful, and postoperative echocardiography revealed no paravalvular leakage.

The patient is a 39-year-old-man who had rheumatic heart disease and had undergone mitral and aortic valve replacements with mechanical St. Jude prostheses as well as tricuspid valve repair and a MAZE procedure 17 years previously. He was admitted with ventricular tachycardia (VT) and an implantable cardioverter-defibrillator (ICD) was implanted. Four months later, he was admitted again with VT, and attempts to manage the VT with drugs were not successful. We performed electro-anatomical mapping and ablation for VT by re-median sternotomy. His postoperative course was uneventful. At 15 months after surgery, no recurrence of VT was recognized.
