The purpose of this study is to develop the non-invesive method for three dimensional analysis of knee extensor and knee flexor muscle groups of the thigh part in human subjects. Our system consisted of magnetic resonance imaging (MRI) to get cross-sectional images of muscle and a computer graphics system which reconstructs three dimensional image of each muscle. The subjects chosen for this study were four healthy male adults, aged from 21 to 30 years. MRI scan was carried out from head of the femur to the upper border of the patella along thigh. Three dimensional (3D) muscular image was reconstructed based on the data from MRI. Referring to the anatomic feature, contour information of knee extensor muscles (KEM) and knee flexor muscles (KFM) was identified on MRI and those muscles were reconstructed to 3 D images using the computer graphics system. This system also provided information on the quantitative volume and cross-sectional area (CSA) of each muscle.
The structure of each muscle of KEM and KFM was displayed by a wireframe model or a surface model on the CRT. It was revealed that 3D muscular images of the surface model using coloring and shadowing were highly effective to understand their shapes and relative location of muscles. CSA and volume of KEM were 86.84±8.38cm²and 2044.25±168.28cm³ and those of KFM were 38.48±5.90cm² and 751.95±50.56cm³ respectively.
These results indicate that not only the anatomical information but also the volume and maximum CSAs of KEM and KFM can be measured quantitatively by this method using three dimensional analysis.

In Palliative care, we meet patients with easy-bleeding superficial malignant tumors, such as head and neck cancer, skin metastasis of all kinds of cancer and unresectable breast cancer. But it is not easy to control bleeding even though we use various means, and many doctors have difficulties in stopping bleeding. We report a case with a recurrent tumor of pharyngeal cancer that showed easy-bleeding and discharged massive exudates. Although she received several alcohol local injections because of bleeding of the tumor, she needed a dressing change over 5 times in a day. It made her QOL worse. In this case, we used Mohs paste and after using it, the surface had been fixed and dried up, resulting in a decrease in bleeding, exudate, frequency of dressing change and bad odor. Mohs paste was made of distilled water, zinc chloride, zinc starch and Glycerol. Zinc chloride changes to zinc ion by water in the wound and makes protein cohere and thereafter tissues, vessels and cell membrane of bacteria are fixed chemically. We could stop bleeding for 15 days with only 20 minutes contact with Mohs paste, and massive exudates and bad odor decreased. Mohs paste, which is made in your hospital pharmacy with cheap materials, can be used for bleeding or massive exudates repeatedly if there is not a thick blood vessel anatomically under the tumor. It was effective to improve her QOL. Palliat Care Res 2009; 4(2): 346-350

The Japanese Society of Hepato-Biliary-Pancreatic Surgery launched the clinical practice guidelines for the management of biliary tract cancers (cholangiocarcinoma, gallbladder cancer, and ampullary cancer) in 2007, then published the 2nd version in 2014. In this 3rd version, clinical questions (CQs) were proposed on six topics. The recommendation, grade for recommendation, and statement for each CQ were discussed and finalized by an evidence-based approach. Recommendations were graded as grade 1 (strong) or grade 2 (weak) according to the concepts of the grading of recommendations assessment, development, and evaluation system. The 31 CQs covered the six topics: (1) prophylactic treatment, (2) diagnosis, (3) biliary drainage, (4) surgical treatment, (5) chemotherapy, and (6) radiation therapy. In the 31 CQs, 14 recommendations were rated strong and 14 recommendations weak. The remaining three CQs had no recommendation. Each CQ includes a statement of how the recommendations were graded. This latest guideline provides recommendations for important clinical aspects based on evidence. Future collaboration with the cancer registry will be key for assessing the guidelines and establishing new evidence.

Objective：The movement of an elderly person involving stepping over a bathtub makes them prone to falls and requires caution. Gait analysis suggested that the risk of falling increases with time spent in supporting both legs. A similar relationship was expected for side-straddling motion. This study aims to analyze differences in the side-straddling movements between THA patients who did not fully recover their functional balance, mobility, or walking ability from the viewpoint of the ratio of time spent supporting both legs.Methods：Eleven patients with hip osteoarthritis underwent initial unilateral THA via a posterior approach. Using a portable three-dimensional motion analyzer, we calculated the percentages of time spent supporting both legs while entering the bathtub, and exiting the bathtub with a handrail and examined the factors associated with percent of the time spent supporting both legs.Results：The percentage of time spent supporting both legs when exiting the bathtub was significantly lesser when exiting using the nonoperative than the operated side. A negative correlation was found between the percentages of time spent supporting both legs. while exiting the bathtub, and the percentage of handrail load values.Conclusion：The risk of falling may be reduced by using the nonoperative leg as the leading leg when exiting a bathtub. Use of handrails contributes to a reduction in fall risk.

Kawasaki disease (KD) is an acute febrile vasculitis predominately affecting infants and children. The dominant incidence age of KD is from 6 months to 5 years of age, and the incidence is unusual in those younger than 6 months and older than 5 years of age. We tried to identify genetic variants specifically associated with KD in patients younger than 6 months or older than 5 years of age. We performed an age-stratified genome-wide association study using the Illumina HumanOmni1-Quad BeadChip data (296 cases vs. 1,000 controls) and a replication study (1,360 cases vs. 3,553 controls) in the Korean population. Among 26 candidate single nucleotide polymorphisms (SNPs) tested in replication study, only a rare nonsynonymous SNP (rs4365796: c.1106C>T, p.Thr369Met) in the lymphoid enhancer binding factor 1 (LEF1) gene was very significantly associated with KD in patients younger than 6 months of age (odds ratio [OR], 3.07; p(combined) = 1.10 × 10⁻⁵), whereas no association of the same SNP was observed in any other age group of KD patients. The same SNP (rs4365796) in the LEF1 gene showed the same direction of risk effect in Japanese KD patients younger than 6 months of age, although the effect was not statistically significant (OR, 1.42; p = 0.397). This result indicates that the LEF1 gene may play an important role as a susceptibility gene specifically affecting KD patients younger than 6 months of age.
