Abstract
Hereditary leiomyomatosis and renal cell carcinoma caused by loss-of-function germline variants of the FH gene can develop into aggressive renal cell carcinoma (RCC). We report the case of a 27-year-old man who died of RCC. Genetic testing revealed a novel pathogenic variant of FH, NM_000143.3:c.1013_1014del (p.Ile338Serfs*3), that was also identified in healthy siblings. Identification of genetic causes in the proband helped us to provide relatives with precise genetic counseling and appropriate surveillance programs.

Abstract
Purpose The aim of this study is to clarify the factors affecting physical function after allogeneic hematopoietic stem cell transplantation (HSCT). Methods We retrospectively analyzed 88 patients (median age, 44.5 years) who received allogeneic HSCT. Leg extension torque and peak oxygen consumption (VO2) were evaluated before and after HSCT. Patient factors (age, sex, underlying diseases, hemoglobin, serum albumin, and Karnofsky performance status score before transplant) and transplant factors (conditioning regimen, days to neutrophil engraftment, grades of acute graft-versus-host disease [GVHD], infections, and the interval between pre- and post-evaluation) were collected via chart review, and were used for correlational and comparison analyses in order to identify the variables associated with reduced post-HSCT leg extension torque and peak VO2. Stepwise multiple regression analyses for post-HSCT leg extension torque and post-HSCT peak VO2 were performed using age, sex, and the related variables with a p value < 0.2 in the correlational and comparison analyses. Results Leg extension torque and peak VO2 were significantly reduced after HSCT (p < 0.001). Pre-HSCT leg extension torque, grades of acute GVHD, age, and the interval between pre- and post-evaluation were identified as significant factors associated with reduced post-HSCT leg extension torque. However, none of these factors were significantly associated with reduced post-HSCT peak VO2, and only its pre-transplant value was identified as a significant factor. Conclusions These findings suggest that improvements in muscle strength and cardiopulmonary fitness before HSCT are crucial for maintaining post-treatment physical function, especially in elderly individuals with acute GVHD requiring a long-term stay in a protective environment.

Abstract
Purpose Active exercise with compression therapy (AECT) is a standard treatment for gynecological cancer-related lower-limb lymphedema (LLL) in clinical situations. However, there is insufficient evidence regarding the immediate effects of the use of AECT on LLL. The purpose of this study was to evaluate the immediate effects of AECT on LLL. Methods Participants in this randomized controlled crossover trial comprised 23 women with LLL who completed high-load AECT, low-load AECT, and compression-only therapy (CT). AECT was performed on a bicycle ergometer with short stretch bandages. Each intervention was performed for 15 min, with successive interventions separated by a 1-week washout period. Lower-limb volume was assessed using a Perometer™ sensor (Pero-system, Wuppertal, Germany). General symptoms (pain and heaviness) and skin symptoms (pitting and stiffness) were assessed using a visual analog scale and palpation, respectively. Measurements were taken before and after each intervention. Analysis of variance using linear mixed-effect modeling was used for statistical analyses. Results Volume decrement differed significantly between all three interventions (P < 0.05). Lower-limb volume was significantly reduced after high-load AECT compared to that after CT. General symptoms and skin symptoms were similar across the three interventions, but severity of pre-intervention skin symptoms correlated significantly with volume decrement after high- and low-load AECT. High-load AECT using the bicycle ergometer was more effective than CT for decreasing lower-limb volume. Conclusions These results suggest that high-load AECT has marked effects on severe LLL.

Abstract
BACKGROUND An objective method to evaluate thoracoabdominal movement is needed in daily clinical practice to detect patients at risk of hypoventilation and to allow for timely interventions in neuromuscular diseases. The clinical feasibility, reliability, and validity of a newly developed method for quantifying respiratory movement using fiber grating sensors, called the Respiratory Movement Evaluation Tool (RMET), was evaluated. METHODS The time needed to measure respiratory movement and the usability of the measurement were determined by 5 clinicians using the Quebec User Evaluation of Satisfaction with Assistive Technology (QUEST) 2.0 questionnaire. Thoracoabdominal movement was measured using RMET 3 times in 10 healthy subjects to evaluate intraclass correlation coefficients (ICC). The subjects were encouraged to breathe 10 times while voluntarily changing the amount of air during ventilation simultaneously with the RMET and a spirometer, and their correlations were evaluated to test validity using Pearson's product-moment correlation coefficients. The same measurements were also performed in 10 subjects with Duchenne muscular dystrophy. RESULTS Real-time recordings of thoracoabdominal movements were obtained over a mean time of 374 ± 23.9 s. With QUEST 2.0, the median score of each item exceeded 3 (more or less satisfied). In healthy subjects, ICC(1,1) ranged from 0.82 to 0.99, and ICC(2,1) ranged from 0.83 to 0.97. Significant correlations were observed between the respiratory amplitudes measured with RMET, and the amount of air during ventilation was measured with a spirometer (r = 0.995, P < .001). In subjects with Duchenne muscular dystrophy, ICC(1,1) ranged from 0.87 to 0.97, and ICC(2,1) ranged from 0.84 to 0.99. The respiratory amplitudes measured with RMET correlated significantly with the amount of air during ventilation with a spirometer (r = 0.957, P < .001). CONCLUSIONS We developed a novel method of quantifying respiratory movement called RMET that was feasible to use in daily clinical practice.

Abstract
Objective: Although palliative care consultation teams (PCTs) have become an integral part of all regional cancer care hospitals, cancer rehabilitation is still in the developing stage in Japan. At our hospital, a physiatrist, or a rehabilitation physician, joined the PCT as a member, and we have been achieving good results. The purpose of this study is to clarify the role of a physiatrist as a member of the PCT by investigating the current status of the PCT at our hospital.Method: We retrospectively analyzed the records of 144 patients receiving rehabilitation out of 345 patients who had started receiving PCT services from April 2012 to March 2013 at Keio University Hospital.Results: Among the 144 patients, 67 patients (46.5%) had already received rehabilitation before starting PCT services, and the remaining 77 patients (53.5%) started receiving rehabilitation based on the recommendation by the physiatrist. In the later group, Dietz Cancer Stage Classifications were: preventative, 6.5%; restorative, 40.0%; supportive, 45.5%; and palliative, 9.1%. ECOG-PS were: PS0, 0.0%; PS1, 23.4%; PS2, 29.9%; PS3, 28.6%; and PS4, 18.2%. The main purposes of rehabilitation were: 1) fracture prevention and pain relief of limbs with bone lesions, 2) social support (e.g. measures for the reduction of nursing requirement, assistance in finding social aids, counseling for family members), 3) psychological support, 4) treatment of lymphedema, 5) management of breathlessness, 6) and approaches to swallowing deficits.Conclusions: Half of the cancer patients started rehabilitation after the intervention by the PCT. Many patients receiving PCT services also needed rehabilitation services and the physiatrist had an important role of evaluating the rehabilitation needs. Physiatrists can act as important members of PCTs to maximize QOL while addressing the physical, psychological, social and spiritual needs of both patients and their families.

Abstract
Lower limb lymphedema is difficult to prevent and diagnose early because its natural history is unclear. Therefore, the aim of this study was to clarify its pathogenesis and to identify risk factors that may lead to early diagnosis. In 29 patients, aged 25 to 74 years with cervical, uterine, or ovarian cancer who underwent pelvic lymphadenectomy, indocyanine green fluorescence lymphangiography was performed with an infrared camera system, and lymph pumping pressure was measured indirectly preoperatively, and one, two, three, and six months postoperatively. Of these 29 patients, 22 (75.9%) completed the examinations. In the non-lymphedema group, the average lymph pumping pressure did not change significantly at postoperative follow-up compared with preoperative values. On the other hand, lymph pumping pressure increased at various time points in five patients who developed early lymphatic changes with dermal diffusion at the level of the proximal femur. An increase in lymph flow path resistance due to pelvic lymphadenectomy resulted in an initial increase in lymph pumping pressure, followed by a subsequent decrease, in the early lymphatic changes group. This trend in the pressure change signifies that the lymph vessels became dysfunctional as they were overwhelmed by the overload condition and this feature may be a clinically useful signal for the early diagnosis of developing lymphedema.

Abstract
Alpha-tocopherol and alpha-tocopherylquinone in rat tissues and plasma were determined simultaneously by using high-performance liquid chromatography-electrochemical detection (HPLC-ED) with dual electrodes in the series mode. Biological samples were saponified in the presence of a mixture of butylated hydroxytoluene, ascorbic acid, and pyrogallol and then extracted with hexane. The compounds were separated on a C18 column using a mobile phase containing 95% methanol and 0.05 M sodium perchlorate as the supporting electrolyte. After HPLC separation, alpha-tocopherylquinone was first reduced at an upstream electrode at -500 mV Both alpha-tocopherol and the reduction product of alpha-tocopherylquinone were then oxidized downstream at +600 mV. Only the downstream electrode current was monitored for the determination. Linearity of the standard curves was obtained over the range 5-30 pmol for alpha-tocopherol and alpha-tocopherylquinone. Minimum detectable quantities (S/N of 3) were 0.25 pmol for alpha-tocopherol and 0.31 pmol for alpha-tocopherylquinone. The method was applied to analysis of the contents of alpha-tocopherol and alpha-tocopherylquinone in rat tissues and plasma. By hyperoxia, the content of alpha-tocopherol was decreased remarkably in lung, and in contrast, the contents of alpha-tocopherylquinone were increased in all tissues studied with the exception of plasma, though the content of alpha-tocopherylquinone in normal rats is quite small. The technique is particularly useful in the quantitation of the oxidation of alpha-tocopherol in biological samples.

Abstract
A high-performance liquid chromatographic method for simultaneous determination of free catecholamines, their basic metabolites and serotonin in human urine was developed. The compounds were separated on a precolumn of cation-exchange resin and a mixed-mode (C18/cation-exchange) column and determined by an eight-channel electrochemical detector. By this method, free norepinephrine (NE), epinephrine (E), dopamine (DA), normetanephrine (NMN), metanephrine (MN), 3-methoxy-tyramine (3-MT) and serotonin (5-HT) were determined in 40 min with inter-assay precision of 1.9, 3.2, 1.2, 1.6, 1.6, 5.5 and 3.2%, respectively. Detection limits were between 0.05 (E) and 0.3 (3-MT) pmol. The mean values of analytical recovery for NE, E, DA, NMN, MN, 3-MT, 5-HT were 99, 104, 104, 99, 102, 109 and 99%, respectively.
