Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) is introduced as a modified two staged hepatectomy for advanced liver malignancies,which requires extended hepatectomy with very small future remnant liver volume.It is characterized by rapid and large growth of future remnant liver and potential of widening the indication of curative resection with extended major hepatectomy for liver malignancies.However,it showed much higher morbidity of complications and mortality than extended hepatectomy after portal vein embolization.The development of ALPPS is often controversial.In this article,the development and problems of ALPPS are retrospected and summarized,in order to reflect the role of ALPPS in Japan where zero mortality after hepatectomy is highly expected.

The location of organs and tissues at the tip of acupuncture needle inserted in acupuncture points was studied on the human transverse sections.
A female, japanese, cadaver (139cm long, and 52kg in weight) was fixed with an aldehyde mixture and frozen for 3 weeks at -30°C. Then the cadaver was cut into blocks along the transverse planes perpendicular to the median plane at each point of Bladder meridian.
This report describes the depth of organs and tissues in 5 transverse planes from DAITSUI (Governor vessel meridian) to KETSUINYU (Bladder meridian).
At DAITSUI, acupuncture needle penetrates through 7.5mm thick skin, 28.5mm thick hypodermis, and reaches to the transverse process of the 7th cervical vertebra at 36mm away from the surface. At DAIJO, the needle penetrates through the skin, hypodermis, trapezius, rhomboideus, and deep back muscles of 6, 8, 5.5, 10 and 14mm in thickness respectively. The needle reaches to the 2nd rib at 43.5mm away from the surface. At FUMON, the needle penetrates through the skin, hypodermis, trapezius rhomboideus, deep back muscles of 7, 5, 3.5, 4 and 18.5mm in thickness respectively. The needle reaches to the 3rd rib at 38mm away from the surface. At HAIYU, the needle penetrates the skin, hypodermis, trapezius, and deep back muscles of 6, 4, 3 and 22mm in thickness respectively, and reaches to the 4th rib at 35mm away from the surface. At KETSUINYU, the needle penetrates the skin, hypodermis, trapezius, and deep back muscles of 5, 3, 4 and 21mm in thickness respectively, and reaches to the 5th rib at 33mm away from the surface.
The depth of acupuncture points studies was discussed from the clinical points of view.

We performed a prospective study to determine whether the walking pattern of children with flatfoot can be influenced by using shoes and custom-modeled insoles. One hundred and thirty-two children (mean age ; 4.20±2.53) who had been referred by a physiatrist, and who were diagnosed with flatfoot at the brace clinic in our institute, were assigned to three groups : The first group was asked to walk barefoot, the second one to walk with shoes without insoles and the last one to walk with shoes with insoles. We measured walking speed, cadence, step length, step width, the duration of right and left stance phases, both double-limb stance phases, both swing phases, walking angle, and toe angle using a 2.4 m sheet-type Gait Analyzer, the Walk Way MW-1000 TM, at the individual's self-selected speed. Compared with the barefoot group, a significant increase was observed in the group using shoes with custom-modeled insoles in both walking speed and step length on both sides, and there were reductions in swing phase and walking angle on both sides (paired t-test ; p<0.002).

Background:
Ameloblastic carcinoma is a malignant form of ameloblastoma and a very rare odontogenic tumor. We report a case of ameloblastic carcinoma that occurred after removal of a right-sided mandibular dental implant.Case presentation A 72-year-old female patient visited her family dentist with a complaint of pain around a lower right implant placed 37 years previously. Although the dental implant was removed with the diagnosis of periimplantitis, the patient experienced dullness of sensation in the lower lip and was followed up by her dentist, but after no improvement. She was referred to a highly specialized institution where she was diagnosed with osteomyelitis and treated the patient with medication; however, there was no improvement. In addition, granulation was observed in the same area leading to a suspicion of malignancy, and the patient was referred to our oral cancer center. The diagnosis of squamous cell carcinoma was made after a biopsy at our hospital. Under general anesthesia, the patient underwent mandibulectomy, right-sided neck dissection, free flap reconstruction with an anterolateral thigh flap, immediate reconstruction with a metal plate, and tracheostomy. Histological analysis of the resected specimen on hematoxylin and eosin staining showed structures reminiscent of enamel pulp and squamous epithelium in the center of the tumor. The tumor cells were highly atypical, with nuclear staining, hypertrophy, irregular nuclear size, and irregular nuclear shape, all of which were suggestive of cancer. Immunohistochemical analysis showed that Ki-67 was expressed in more than 80% of the targeted area, and the final diagnosis was primary ameloblastic carcinoma.
Conclusion
After reconstructive flap transplantation, occlusion was re-established using a maxillofacial prosthesis.The patient remained disease-free at the 1-year 3-month follow-up.

We report on a case of severe generalized pain due to fibromyalgia syndrome, which was successfully treated with a variation of byakkoto. A 65-year-old Japanese woman had severe generalized pain which grew worse in warm environments, such as during the summer or when bathing. She also had pollakidipsia. We utilized a variation of byakkoto on the assumption that she was suffered from high inner heat. Her severe generalized pain resolved with this therapy. Although bushi-zai and saiko-zai are common prescriptions for fibromyalgia syndrome, byakkoto-variations may also be effective in cases where conditions are worsened by heat effect.

Lower limb skin ulcers due to arteriosclerosis obliterans are severe ischemic lesions, and if preservation therapies such as antiplatelet and anticoagulant treatments are not effective, lower limb amputation may be necessary.We report the case of 73 year-old male patient suffering from intermittent claudication and skin ulcers on the heel of the left foot, who was successfully treated with keishibukuryogan and daisaikoto prepared in hospital. This case suggests that improvement of micro circulation with the addition of keishibukuryogan and daisaikoto to anticoagulant and antiplatelet therapies, safely promoted an improvement of ischemic lesions due to arteriosclerosis obliterans.

The clinical competence needed by every beginning resident and the present status of such competencewere examined in August 1998 through questionnaires distributed to clinical educators and the nursing staff of university hospitals and clinical training hospitals designated by the Ministry of Health and Welfare. Completed questionnaires were returned by 576 (65.9%) of clinical educators and nursing staff. With a cluster analysis of the necessity and the present status of clinical competence, 21 items for clinical competence were identified as those most requiring evaluation by the national examination. These 21 items included 11 items for clinical competence in the cognitive domain, 8 items in the psychomotor domain, and 2 in the affective domain. In about half of the direct answers obtained from clinical educators, evaluations were considered necessary for 15 items of clinical competence, of which 13 belonged to the cognitive domain. These results were consistent with the present status. However, practical examinations have also attracted increasing attention, as the results included strong demands that the national examination evaluate some basic clinical skills, such as physical examination and measurement of vital signs. However, about 30 % of authorities governing the national examination thought no changes are needed in the national examination.

Purpose:
Autoregulation of retinal vessels is stronger than that of choroidal vessels. This study aimed to use laser speckle flowgraphy to determine the time course of changes in retinal hemodynamics of healthy eyes after a cold pressor test.
Methods:
This prospective study included 44 right eyes of 44 healthy volunteers (age, 21.7 ± 5.0 years). The mean blur rate, which is a quantitative index of the relative blood flow velocity in the retina, was measured using laser speckle flowgraphy. The vessel average of mean blur rate at the optic nerve head, intraocular pressure, systolic blood pressure, diastolic blood pressure, mean blood pressure, heart rate, and ocular perfusion pressure were evaluated at baseline, immediately after the cold pressor test, and 10, 20, and 30 minutes after the test.
Results:
Immediately after the test (0 minutes), systolic blood pressure, diastolic blood pressure, mean blood pressure, and ocular perfusion pressure were significantly increased compared with those at baseline; however, no changes were observed at 10, 20, and 30 minutes after the test. In contrast, intraocular pressure, heart rate, and the vascular mean blur rate values at the optic nerve head did not change throughout the course of the study.
Conclusions
Sympathetic hyperactivity induced by the cold pressor test increased systemic circulatory dynamics, but not retinal circulatory hemodynamics, suggesting the involvement of vascular autoregulation.
