Skeletal muscle is one of the most unusual sites of metastasis from any malignancy. We report herein a case of hilar cholangiocarcinoma with synchronous metastases to skeletal muscle and breast, and review the literature. The patient was a 48-year-old woman who presented with jaundice and weight loss. An inoperable hilar cholangiocarcinoma was diagnosed. She was treated with a combination of endoscopic plastic stent biloiary drainage and three-dimensional conformal radiotherapy （3DCRT）. Good response was achieved. Ten months later, she exhibited with a painful metastatic mass in the muscle rectus femoris of left thigh and a painless mass in the left breast. She underwent operation to relieve the pain, but died from liver failure after 8 months. The literature only offers isolated cases of cholangiocarcinoma with distant metastases, of which the common sites were cervical lymph node, bone, and portal venous system. Most patients were presented with multiple metastases with extensive local disease.展开更多

However this achievement is still be overshadowed by the harvesting method which is conventional and labor intensive. An attempt to use mechanization into the harvesting system, in particular the cutting process of tall palm trees, has been unsuccessful. At the beginning of the oil palm＇s fruit bearing fife, i.e. 3 to 4 years of age, fi＇uit bunches are still accessible. For these palms, a chisel is used to cut the fiuit bunches. Growth is such 8-10 years, and the trees have already reached substantial height. In these cases a sickle mountedon flexible telescopic aluminum tube （pole） is used. This, however, exposes plantation worker to the risk of musculoskeletal discomfort and injury. This paper examines the problems by assessing the task posture and tool, and their implications for operators, using questionnaire survey and videotape analysis techniques. The result prevails that there is evidence to associate the problems of musculoskeletal disorders among the operators.展开更多
