Objectives: This study aimed to determine the relationship between the number of board-certified physiatrists and the amount of inpatient rehabilitation delivered.Materials and Methods: We analyzed open data from 2017 in the National Database of Health Insurance Claims and Specific Health Checkups of Japan and compared the volume of inpatient rehabilitation services between prefectures to examine regional disparities. We also examined the relationship between the volume of rehabilitation services provided and the number of board-certified physiatrists.Results: The population-adjusted number of inpatient rehabilitation units per prefecture ranged from a maximum of 659,951 to a minimum of 172,097, a disparity of 3.8-fold. The population-adjusted number of board-certified physiatrists was 4.8 in the highest region and 0.8 in the lowest region, a disparity of 5.8-fold. The population-adjusted number of board-certified physiatrists was significantly correlated with the population-adjusted total number of inpatient rehabilitation units (r=0.600, P<0.001). Correlations were between the number of board-certified physiatrists and the number of rehabilitation units in cerebrovascular and orthopedic services, but not in cardiovascular, respiratory, or oncology services.Conclusion: Large regional disparities manifested in the amount of inpatient rehabilitation provided in Japan. An association was found between the number of board-certified physiatrists and rehabilitation units delivered. It may be necessary to train more BCPs in regions with fewer units to eliminate these disparities.

Methods: For this prospective multicenter study, 40 patients were followed up through radiologic and clinical examinations for at least 1 year postoperatively. All surgical procedures were either single- or double-level LLIF using bioactive porous titanium spacers without bone grafts. Results: Four patients were excluded from the study owing to aggravation from other comorbidities. Another 36 patients, including 26 and 10 with single- and double-level LLIFs, respectively, participated in the follow-up. The mean age at the time of surgery was 63.7 years. The mean operating time was 50.5 minutes per level. The mean estimated intraoperative blood loss was 11.6 mL per level. Clinical scores improved in all cases and were maintained throughout the follow-up period. The intervertebral bony union rates were 67.4% and 84.8% at 6 and 12 months, respectively. Endplate cyst signs were observed in 13.0% and 8.7% of patients at 6 and 12 months, respectively. Fused segmental angles were maintained throughout the follow-up period, indicating no cage subsidence. Conclusions Single- and double-level LLIFs using bioactive porous titanium spacers without bone grafts were found to be minimally invasive, resulting in clinical and imaging results comparable with conventional procedures. Therefore, this type of implant may be an option for minimally invasive spinal fusion surgery.

Although palliative sedation therapy (PST) is considered to alleviate intolerable and refractory symptoms in dying patients with advanced cancer, there have been few studies regarding the situation of tertiary cancer center. We conducted a retrospective survey of the medical records of the patients who died between April 2015 and March 2016 at the National Cancer Center Hospital in Japan. PST was conducted in 75 out of 431 patients (17.4%). The patient demographics were as follows: sex (male/female), 48/27; median age, 61 years (range 5-83; 11 patients (14.7%) were aged under 39 years); and primary sites were lung, 18 (24.7%)/ pancreas, 11 (14.7%)/ hematopoietic organs, 11 (14.7%)/ bones and soft tissues, 8 (10.7%)/ and the others, 27 (36.0%). The main target symptoms for PST were dyspnea (38, 50.7%) and delirium (30, 40.0%). The most commonly used sedative agent was midazolam (72, 96.0%). Continuous deep sedation was intended in 61 patients (81.3%) at the death. Median survival from the start of PST were 2 days (range 0-54). The differences between palliative care team (PCT) intervention group and control group were lower age (58 vs. 62.5, P=0.048) and uniformity of initial midazolam dose (5-12 vs. 9.6-25.2 mg/day). Distinctive feature in this study was large proportion of adolescent and young adult patients with rare cancers. PCT might have different approaches to sedation in comparison to non-PCT medical staffs.

Background: Adolescents and young adults (AYA) with cancer go through various life events during their illness trajectory, and there is often insufficient information on their diseases due to their rarity. Few chances are available for AYA patients to meet and share information with each other. Therefore, at the National Cancer Center Hospital in Japan we hold AYA Hiroba, a monthly get-together for AYA patients to communicate with each other. This study investigated satisfaction and effect with the activity. Methods: We have held the AYA Hiroba activity once a month since May 2016. We asked participants to complete a questionnaire at each session.Results: We held the activity 33 times between May 2016 and May 2019. A total of 130 patients participated, and 97 of them completed the questionnaire, including providing demographic data, since October 2017. The respondent demographics were as follows: sex (male/female), 38/59; median age, 29 years (range 14–39 years); outpatients/inpatients, 31/66; number of sessions attended (1/≥2), 42/55; and cancer type (sarcoma/malignant lymphoma/brain tumor/germ cell tumor/leukemia/melanoma/breast cancer/neuroblastoma/Wilms tumor/lung cancer/cervical cancer/nasopharyngeal cancer/tongue cancer/blank), 45/11/9/7/6/5/3/3/2/1/1/1/1/2). Many attendees perceived the activity favorably: “It was very satisfying” (61.7%), and “It was very helpful” (65%). The feedback was classified into three categories: “interaction with the same generation”, “diversion”, and “getting information”. Discussion: AYA patients have a great need to communicate with each other, and the feedback suggests that AYA Hiroba would be effective in interaction with the same generation, diversion and getting information. Most participants were very satisfied with the program.

BACKGROUND: An increase in cardiovascular diseases has been reported following major disasters. Previous work has shown that ultrasonographic findings from ultrasound cardiography examination (UCG) increased until the 44th month after the tsunami caused by the Great East Japan Earthquake. The present study conducted UCG among victims in the tsunami disaster area and investigated the frequency of disaster-related cardiovascular diseases and changes over time until the 55th month after the disaster. METHODS: The subjects were residents of temporary housing complexes and neighboring housing in Watari-gun, Miyagi Prefecture, Japan. There were 207 subjects in the 18th month, 125 in the 30th month, 121 in the 44th month, and 106 in the 55th month after the disaster. Data were collected through UCG and self-report questionnaire. RESULTS: Significant changes were observed among subjects with clinical findings from the UCG, which increased over the study period-from 42.0 to 60.8, 72.7, and 73.6% beginning in the 18th month after the disaster (p < 0.0001). CONCLUSIONS: It is possible that the UCG can become a useful examination to visualize the potential impact of a major disaster on the cardiac function of victims. Victims with clinical findings continued increasing not only during the acute phase after a disaster but also in the long term. We therefore need to keep this in mind, and note that it is important to establish a support system to control cardiovascular diseases from the early stage of disaster.

Introduction: Due to the advancement of the home-based healthcare, increasing the number of professionals who are able to administer homebased treatments, such as endotracheal suctioning, is an urgent issue.Methods: By measuring the ocular movement of nurses, nursing students and previous researches, an endotracheal suctioning ontology was visualized. It included a multiplex task structure, recognition, and judgment, as well as identifying procedures used during endotracheal suctioning that could contribute to a discussion on educational feasibility.Results: From the hierarchical structure of the constructed endotracheal suctioning ontology, not only the procedural knowledge but also knowledge about medical devices, knowing what options exist when endotracheal suctioning is ineffective, and a wide range of other expertise is needed to perform endotracheal suctioning safely.Discussion: An endotracheal suctioning ontology was created from the ocular movement of nurses. Ontologies are a potential tool for defining minimum requirements and the scope of ability that must be evaluated before clinical practicum.

Objective: Patients with secondary hyperparathyroidism caused by chronic kidney disease (CKD) develop secondary osteoporosis, which increases fracture risk. We report a case of insufficiency fractures complicated by secondary osteoporosis caused by chronic renal failure and gastrectomy.
Patient: A 78-year-old man with a medical history of nephrotic syndrome and gastric cancer experienced an occult intertrochanteric fracture of his left femur after falling.
Results: Ten days after the first fracture, the patient was treated with hemodialysis for acute uremic symptoms. Eight weeks after this fracture, he sustained a right insufficiency acetabular fracture and was treated with total hip arthroplasty (THA).
Conclusion: For patients with CKD, effective fracture prevention is difficult. THA with reconstruction of the acetabulum was an effective therapy in a patient with nontraumatic central fracture dislocation of the hip.

Objective:Delayed gastric emptying (DGE) after pylorus-preserving pancreatoduodenectomy (PpPD) is a persistent and frustrating complication. To preserve pylorus ring with denervation and devascularization may be a risk factor of DGE after pancreaticoduodenectomy. We conducted this study to confirm the hypothesis that pylorus-resecting pancreatoduodenectomy (PrPD) reduces the incidence of DGE compared to PpPD. Moreover, long-term outcomes of PrPD and the adverse effect of postsurgical DGE on long-term outcomes have not been reported. Therefore, in addition, this study focused on long-term outcomes during 24 months after surgery between PrPD versus PpPD. Methods: Between October 2005 and March 2009, at Wakayama Medical University Hospital (WMUH), 130 patients with pancreatic or periampullary lesions were randomized to preservation of the pylorus ring (PpPD) or to resection of the pylorus ring (PrPD). In PpPD, the proximal duodenum was divided 3-4cm distal to the pylorus ring. In PrPD, the stomach was divided just adjacent the pylorus ring and the nearly total stomach more than 95% was preserved. Shortterm and long-term outcomes were evaluated between PpPD and PrPD. Primary endpoint is the incidence of DGE. DGE was defined according to a consensus definition and clinical grading about postoperative DGE proposed by the international study group of pancreatic surgery (ISGPS). This RCT was registered at Clinical Trials.Gov NCT00639314. Results: Of 130 patients who were enrolled in this study, 64 patients were randomized to PpPD and 66 to PrPD. The overall incidence of DGE in this RCT was 10.8% (14 of 130 patients); the overall incidence of DGE was significantly lower in PrPD (4.5%) than PpPD (17.2%) (P =0 .0244). DGE was classified into three categories proposed by the International Study Group of Pancreatic Surgery. The proposed clinical grading classified 11 cases of DGE in PpPD into grades A (n=6), B (n=5), and C (n=0), and one case in PrPD into each of the three grades. In long-term outcomes, weight loss > grade 2 (Common Terminology Criteria for Adverse Events, Ver. 4.0) at 24 months after surgery improved significantly in PrPD (16.2%) compared with PpPD (42.2%) (P = 0.011). Nutritional status and late postoperative complications were similar between PpPD and PrPD. The incidence of weight loss greater than Grade 2 at 24 months after surgery was 63.6% in patients with DGE group and 25.3% in patients without DGE group (P = 0.010). Tmax (the time to peak 13CO2 content in 13C-acetate breath test) at 24 months after surgery in patients with DGE was significantly delayed compared with those without DGE (27.9 ± 22.7min vs.16.5 ± 10.1min, P=0.023). Serum albumin at 24 months after surgery was higher in patients without DGE than those with DGE (3.7±0.6 g/dl vs. 4.1±0.4 g/dl, P=0.013). Conclusion: This study clarified that PrPD can lead to a significant reduction in the incidence of DGE compared with PpPD. Moreover, PrPD offers similar longterm outcomes with PpPD. DGE may be associated with weight loss and poor nutritional status in long-term outcomes.

Background: Necrotizing fasciitis is a rare but severe condition associated with high mortality. We encountered a patient with severe and rapidly progressing necrotizing fasciitis. Patient: A 40-year-old male was hit by a tractor and received a wide laceration wound spanning the length of his posterior thigh. Soon after the accident, the wound was washed and debridement was performed. Two days postoperatively, we observed septic changes in the wound and diagnosed this condition as necrotizing fasciitis. Consequently, the patient's leg was amputated at the thigh. The patient, however, developed toxic shock syndrome after the amputation. Endotoxin adsorption using a polymyxin B-immobilized fiber column was performed for 2 days. Finally, a hip joint amputation was performed after 11 days, following which the patient's general condition gradually improved. Discussion: Treatment for necrotizing fasciitis should be initiated promptly. Early debridement is associated with a significant decrease in mortality. In severe conditions, endotoxin and cytokine removal by blood purification is one of the most effective treatments. Although group A streptococci are widely known as "flesh-eating bacteria," we should also consider a wide variety of pathogenic organisms to be the probable cause of severe necrotizing fasciitis. Conclusion: Management of necrotizing fasciitis requires careful investigation as well as an aggressive therapeutic approach, which may include urgent surgical intervention. In addition to surgery, endotoxin adsorption therapy should be considered.
