Musculoskeletal disorders in workers decrease the productivity of companies and result in socioeconomic losses. Low back pain accounted for approximately 60% of occupational diseases in the past and this is still true at present, making it a major occupational health problem in Japan. Herein, the findings about low back pain are explained as follows: the correlation between imaging examination findings and low back pain is low; psychosocial factors are involved in the onset of low back pain and how it becomes chronic; and improvement of activity is more useful than rest. Furthermore, the advantages of employing physical therapists for improving occupational health are as follows: they can 1) evaluate and intervene ergonomically; 2) provide instructions using a behavioral modification technique based on psychosocial factors; and 3) provide instructions regarding exercise programs considering obstacles to the development of a good exercise habit (painful diseases including osteoarthritis and other diseases such as hypertension and diabetes). In addition, falling, whose incidence has recently been increasing and is an important issue in occupational health, is examined from the aspect of musculoskeletal disorders. The following activities of physical therapists are introduced: the items to be checked during a tour of inspection of a workplace and detailed descriptions of work management and working environment management measures. Physical therapists are rarely involved in studies of low back pain and falling, but their knowledge and skills have been demonstrated to contribute to improving occupational health.

STUDY DESIGN.: Retrospective study. OBJECTIVE.: We sought to determine the long-term outcomes of laminoplasty versus anterior decompression and fusion in the treatment of cervical myelopathy caused by ossification of the posterior longitudinal ligament (OPLL) and to ascertain what factors should be considered in selecting appropriate surgical procedure. SUMMARY OF BACKGROUND DATA.: There are little data about long-term results of cervical myelopathy due to OPLL with an occupying ratio 60% or more. METHODS.: We retrospectively studied 27 patients having OPLL with an occupying ratio 60% or more and a follow-up period of at least 2 years. Clinical outcome was evaluated using Japanese Orthopaedic Association scores and recovery rates (≥75%, excellent; 50%-74%, good; 25%-50%, fair; and <25%, poor). RESULTS.: The mean age and the mean duration of follow-up were 57 years and 10.2 years. The mean Japanese Orthopaedic Association score was 9.3 before surgery and 12.4 at the final follow-up examination. There were 15 patients in the laminoplasty group (LAM group) and 12 patients in the anterior decompression and fusion group (ADF group). The ADF group had a significantly better recovery rate at final evaluation (53% vs. 30%; P = 0.04), a longer duration of surgery (314 vs. 128 min; P < 0.01), and greater blood loss (600 vs. 240 mL; P < 0.01) than did the LAM group. In the LAM group, 4 patients with excellent or good results had a significantly larger degree of cervical lordosis (30 vs. 10 ; P = 0.002) than others. CONCLUSION.: The ADF group had a significantly better recovery rate than the LAM group, although the degree of surgical invasiveness was high. ADF is generally recommended for OPLL with an occupying ratio 60% or more. © 2013, Lippincott Williams & Wilkins.

One of the most important sequelae affecting long-term results is adjacent-segment degeneration (ASD) after posterior lumbar interbody fusion (PLIF). Although several reports have described the incidence rate, there have been no reports of repeated ASD. The purpose of this report was to describe 1 case of repeated ASD after PLIF. A 62-year-old woman with L-4 degenerative spondylolisthesis underwent PLIF at L4-5. At the second operation, L3-4 PLIF was performed for L-3 degenerative spondylolisthesis 6 years after the primary operation. At the third operation, L2-3 PLIF was performed for L-2 degenerative spondylolisthesis 1.5 years after the primary operation. Vertebral collapse of L-1 was detected 1 year after the third operation, and the collapse had progressed. At the fourth operation, 3 years after the third operation, vertebral column resection of L-1 and replacement of titanium mesh cages with pedicle screw fixation between T-4 and L-5 was performed. Although the patient's symptoms resolved after each operation, the time between surgeries shortened. The sacral slope decreased gradually although each PLIF achieved local lordosis at the fused segment. ©AANS, 2014.

We report a case in which recurrent pancreatic metastasis of renal cell carcinoma( RCC) in the remnant pancreas was resected 6 years after subtotal stomach-preserving pancreaticoduodenectomy (SSPPD). A 74-year-old man underwent right nephrectomy for RCC in 1991, left partial nephrectomy for left renal RCC metastasis in 1996, and SSPPD for pancreatic RCC metastasis in 2007. In November 2012, he was referred to our hospital with a tumor in the remnant pancreas, as seen on abdominal computed tomography (CT). Partial pancreatectomy for the recurrent metastatic RCC in the remnant pancreas was performed in January 2013. The tumor was histologically diagnosed as metastasis from clear cell RCC in the remnant pancreas. The postoperative course was uneventful, and the blood glucose level after surgery was well controlled using an oral hypoglycemic agent.

Ovarian vein thrombosis usually occurs in pregnant patients, especially during the postpartum period. However, it is a rare complication following laparoscopic surgery in gynecology. The risk of a thromboembolic event is not well defined, and evidence-based guidelines regarding deep vein thrombosis prophylaxis in gynecological laparoscopic surgery are still lacking. Herein we report a rare case of ovarian vein thrombosis following total laparoscopic hysterectomy in a 35-year-old woman who developed a fever of unknown origin on postoperative day 3. A complete fever work-up was done. Her urine, vaginal stump and blood culture were all negative, and her white blood cell count was normal. CT revealed left ovarian vein thrombosis. The patient responded well to anticoagulation in conjunction with antibiotic therapy. © 2012 Japan Society for Endoscopic Surgery, Asia Endosurgery Task Force and Wiley Publishing Asia Pty Ltd.

Fecal diversion may be performed using various techniques. Each technique has advantages that affect patient selection. In this report, we report our experience with 31 patients who underwent single-incision laparoscopic stoma creation using only a pre-selected stoma site as the point of port access. A 2.5-cm skin incision was made at a previously marked stoma site, and two 5-mm trocars were placed into the abdomen through the stoma site. An optional third trocar was inserted at the stoma site only if the bowel needed to be mobilized or if adhesions needed to be divided. After full intra-abdominal exploration, a selected intestinal loop was brought up to the stoma site, and the ostomy was then matured using standard techniques. Between April 2009 and March 2012, 31 patients (19 men) with a mean age of 68 years (range, 46-87 years) underwent single-incision laparoscopic stoma creation. Fecal diversion included ileostomy (n = 18) and colostomy (n = 13). There were no intraoperative complications. Two patients (6.5%) required additional port placement in the midline suprapubic area. Conversion to open laparotomy was required in two patients (6.5%) because of the presence of extensive adhesions. Postoperative complications were observed in two patients and included peristomal ileus and dehydration due to high ileostomy output. Single-incision laparoscopic stoma creation is an effective technique that allows full intra-abdominal visualization and bowel mobilization, while reducing the need for additional skin incisions beyond that of the stoma site. © 2013 Japan Society for Endoscopic Surgery, Asia Endosurgery Task Force and Wiley Publishing Asia Pty Ltd.

We compared treatment outcomes of stereotactic ablative body radiation therapy (SABR) in octogenarians with early (T1-2N0M0) lung cancer with the outcomes in younger patients. Fifty-three patients were octogenarians (Group A) and 127 patients were younger (Group B). The 3-year survival rates were 44% and 59%, and the 3-year cause specific survival rates were 59% and 71% in groups A and B, respectively (p = 0.70 and p = 054). The treatment outcomes of SABR in octogenarians were comparable to those observed in younger patients.

Purpose: To report 5 cases of severe intraocular inflammation that developed after an intravitreal injection of the same lot of bevacizumab. Design: Retrospective case series. Participants: Patients treated with an intravitreal injection of bevacizumab (lot B3003B01). Methods: The clinical charts of 35 eyes of 35 consecutive patients who were treated with intravitreal injection of lot B3003B01 bevacizumab from December 18, 2008, through January 20, 2009, were reviewed. Main Outcome Measures: Incidence of intraocular inflammation, results of bacterial cultures, best-corrected visual acuity (BCVA), and endothelial cell density. Results: Five (14.3%) of the 35 cases had severe intraocular inflammation, and the inflammation had some characteristics of toxic anterior segment syndrome (TASS). Five of the 5 cases had a predominantly anterior chamber reaction, and 4 of the 5 cases were accompanied by hypopyon. Undiluted samples collected from both the aqueous and vitreous of the 5 cases were culture negative. The BCVA was 0.66±0.29 (mean±standard deviations) logarithm of the minimum angle resolution (logMAR) units, and the endothelial cell density was 2683.6±97.3/mm2 before the intravitreal bevacizumab. At the final visit, the BCVA was 0.44±0.36 logMAR units, and the cell density was 2679.0±217.5/mm2. These differences were not significant (P = 0.171 and 0.964). Conclusions: These observations indicate that an intravitreal injection of bevacizumab can induce sterile endophthalmitis that has characteristics of TASS.

Rotavirus is the single main cause of severe acute gastroenteritis in children less than 5 years of age, resulting in over 527,000 deaths worldwide annually. The majority of rotavirus-related deaths are seen in less-developed countries; in developed countries, rotavirus is an infrequent cause of death but a commom cause of hospitalizations. Rotavirus gastroenteritis was also estimated to result in approximately 790,000 doctor visits every year leading to medical intervention among children aged 0-5 years in Japan. At present, the treatment of rotavirus gastroenteritis in Japan is limited to symptomatic measures and no antiviral therapy is available. A phase III, randomized, double-blind study evaluated the efficacy, reactogenicity, safety and immunogenicity of a human rotavirus vaccine in Japanese infants. Rotavirus vaccine was efficacious, well-tolerated and immunogenic in Japanese infants and introduction of vaccination would help in reducing the disease burden.
