Our hospital is located in a mountainous region of Toyota City, Aichi Prefecture. In the sphere covered by our health services, about 34% of the population is 65 years or older. The graying of the community has been progressing rapidly in the past years. Many elderly people do not have a car. Only available means of transport for them are community bus servicers operated once or twice a week. The situation makes them feel disinclined to go to take physicals or visit the hospital for health screening. When we happen to detect gastrointestinal cancer in aged persons, it is often in an advanced state or too late for surgical removal, or a relapse. For some of such cases, we consider the possibilities of chemotherapy.
Between April 2005 and June 2010, we performed laparotomies (including exploratory operations) on people aged 70 or older with gastrointestinal cancer. Of the patients excluding those with severe cognitive impairment and those in failing health, 25 patients underwent S-1monotherapy postoperatively. The results were no less favorable than those of the cases of younger patients who had received S-monotherapy or other forms of chemotherapy for gastrointestinal cancer. Although this comparison was not adequate because the number of cases of elderly patients was too small, our hospital regards S-1 monotherapy as one of the chemotherapeutic regimens beneficial to old people with gastrointestinal cancer and helpful in maintaining the patient's qualuty of life.

Moist wound healing for wound treatment has been becoming wide-spread for several years. Open wet-dressing therapy (OWT) is one of the useful therapies at a hospital in a mountainous area where many elderly find it difficult to go to hospital frequently the past. At our department of surgery we also heal pressure ulcers, so we regard Wound bed preparation as important, too. Choice of appropriate types of dressing materials based on concept of Wound bed preparation and Moist wound healing, OWT and information of them enable us to decrease the frequency of hospital visits by the elderly in the mountainous area. It is important for the community in the mountainous area to inform Wound bed preparation, Moist wound healing and OWT for the purpose of safety management of OWT.

Necrotizing fasciitis has a very high acute mortality. Diabetes mellitus often underlies the disease. In this paper, we report two cases of necrotizing fasciitis caused by sacral decubitus, which were successfully treated with withdrawal of pus through radical excision, cleansing and debridement. The patients were: a 74-year-old man with a history of diabetes and depression (case 1) and a 82-year-old man with a history of diabetes and spinal injury which resulted in paraplegia (case 2). In either case, a wide area extending from the buttocks to lower back was cut open for drainage, washing and debridement at an early stage after the onset of necrotizing fasciitis, and broad-spectrum antibiotics were administered. Due to preoperative general health conditions, underlying diseases such as diabetes mellitus and postoperative diapedesis of protein, the patients' nutritional status critically deteriorated after surgery. Consequently, measures were taken to control diabetes and provide nutritional care. These efforts were crowned with success. It was found that early healing of surgical wound necessitated using pressure dispersion type mattresses and turning, on a regular basis, of the bed-ridden patients with decreased mobility, in addition to putting them in rehabilitation.

Between 1974 and 1991, we treated 10 aortic arch branch aneurysms in eight men and two women, who ranged in age from 17 to 81 years old (mean age, 55 years). Five patients had subclavian artery aneurysms, four had carotid artery aneurysms, and one had an inominate artery aneurysm. The chief complaint was a mass on the neck and supraclavicular fossa in five patients, rupture and an abnormal shadow on chest X-rays in two patients each, and acute artery occlusion in the upper limb in one patient. The operative method was usually excision of the aneurysm and reconstruction. The causes were arteriosclerosis in five patients, the thoracic outlet syndrome in two patients, and inflammatory, traumatic and iatrogenic in one patient each. Intraoperative hemorrhage occurred in one patient and graft occlusion in another one. The other patients have had a good course. This disease is rare, but because of complicated rupture and acute artery occlusion, it is desirable to perform surgery as soon as possible after the first diagnosis.

A 62-year-old man was admitted to our hospital because of acute aortic dissection (DeBakey type III b). Inflammatory findings were detected and methicillin-resistant staphylococcus aureus (MRSA) was detected by blood culture. Appropriate antibiotic therapy was begun but was ineffective. Repeated CT scans revealed dilation of the false lumen with thrombus and perianeurysmal inflammatory change in the lung. A diagnosis of infected aortic dissection was made. The patient was treated by resection of the descending aorta and placement of an in situ Dacron graft covered with a pedicled omental flap. An infected thrombus in the false lumen was confirmed by a positive MRSA culture. Computed tomography was found to be more sensitive in the diagnosis of infected aortic dissection. When the infection is not controlled with antibiotics, prompt surgical treatment should be performed.

Advances in genetic medicine has rapidly been applied to clinical practice. However, many medical students have not studied biology or genetics in high school. There is little chance to think in Japan medical education about how to treat genetic information appropriately in the setting of clinical medicine. The timing and contents of a clinical genetics education program in medical school has hardly been discussed in Japan. This paper discusses the clinical genetics educationduring the medical-science and clinical-medicine stages at Nippon Medical School.
1) An exercise on information gathering and role-play (for 180 minutes) about color vision deficiency were performed during the second-year molecular genetics course.
2) A clinical genetics course (45 minutes 18 classes) in the fourth year was started in 2002 as a part of an integrated medical curriculum with courses classified by organ system.
3) This clinical genetics course included systematic lectures for knowledge acquisition, lectures by patient support groups, exercises in drawing pedigrees, role-play, and discussions of ethical issues. Students evaluated this course favorably.
4) Some topics in clinical genetics can be effectively presented at an early stage of medical education as part of an introduction to medicine. To maximize the educational effects and increase the possibility that students understand the importance of medical genetics, clinical genetics education in medical school will be performed after the student have grasped a basic understanding of diseases through lectures about clinical subjects.

Three ultrasound parameters-broad band ultrasound attenuation (BUA), speed of sound (SOS) through the heel and average of standardized BUA and SOS (stiffness)-were measured with a LUNAR Achilles system (Lunar Corporation, Madison, WI, USA) in 9459 normal Japanese women (mean±SD 54.7±11.3yr, 15-90 yr) who have no history of ovariectomy, and 260 men (58.1±16.5 yr, 15-86 yr).
The bone mass values peaked in women aged 15-17 years (BUA 116±9, SOS 1572±23 and stiffness 97±11), and in men aged 15-16 (SOS 1590±20, stiffness 107±11) and in the age span 22-29 years (BUA 124±14).
The rates of bone loss were high in women aged 51-55 (stiffness 1.0%/yr), significantly high in the women who had been menopausal for less than 5 years (stiffness 2.0% yr).
We compared the mean values of the parameters in women with early menopause (≤45 yr) and late menopause (≥53 yr) more than 5 years after the menopause. In the early menopausal women, the mean BUA values at age 58-62, and those of BUA, SOS and stiffness at age 63-67 were significantly low (P<0.02) compared with the age-matched values in the late menopausal women, whereas no significant difference was observed between those in either of the two groups after 68 years of age.
There were significantly positive correlations between the 3 ultrasound parameters and height, body weight and obesity index, but SOS was not significantly correlated with body mass index.
These results indicate that the maximal bone mass in the os calcis is attained in very young women aged 17 or less and that loss in the calcaneus bone quality appears to be more dependent on menopause than aging in women 58-67 years old. In the older women, however, the loss of bone seems to be age-related.

We report the first case demonstrating an association between Kawasaki disease (KD) and erythema nodosum (EN). A 3-year-old girl presented with EN as an initial manifestation of KD. At the initial visit, she showed high fever of 40℃, injection of the oropharynx, cervical lymphadenopathy, and red-purple cutaneous nodules, particularly on the lower limbs. She complained of severe pain in the neck and cutaneous lesions. Initially, the development of EN was attributed to Salmonella spp infection, which was detected in stool culture. However, the patient did not respond to high-dose ampicillin/sulbactam to which the Salmonella spp is sensitive. Echocardiography performed as screening for fever of unknown origin revealed medium-sized aneurysms of the left anterior descending artery. EN masked the diagnosis of KD, and the patient developed a coronary artery lesion. KD should be considered in the differential diagnosis of refractory EN in pediatric patients.

PURPOSE: Oxidized low-density lipoprotein (oxLDL) plays a key role in endothelial dysfunction, vascular inflammation, and atherogenesis. The aim of this study was to assess blood clearance and in vivo kinetics of radiolabeled oxLDL in mice.METHODS: We synthesized ¹²³I-oxLDL by the iodine monochloride method, and performed an uptake study in CHO cells transfected with lectin-like oxLDL receptor-1 (LOX-1). In addition, we evaluated the consistency between the ¹²³I-oxLDL autoradiogram and the fluorescence image of DiI-oxLDL after intravenous injection for both spleen and liver. Whole-body dynamic planar images were acquired 10 min post injection of ¹²³I-oxLDL to generate regional time-activity curves (TACs) of the liver, heart, lungs, kidney, head, and abdomen. Regional radioactivity for those excised tissues as well as the bladder, stomach, gut, and thyroid were assessed using a gamma counter, yielding percent injected dose (%ID) and dose uptake ratio (DUR). The presence of ¹²³I-oxLDL in serum was assessed by radio-HPLC.RESULTS: The cellular uptakes of ¹²³I-oxLDL were identical to those of DiI-oxLDL, and autoradiograms and fluorescence images also exhibited consistent distributions. TACs after injection of ¹²³I-oxLDL demonstrated extremely fast kinetics. The radioactivity uptake at 10 min postinjection was highest in the liver (40.8 ± 2.4% ID). Notably, radioactivity uptake was equivalent throughout the rest of the body (39.4 ± 2.7% ID). HPLC analysis revealed no remaining ¹²³I-oxLDL or its metabolites in the blood.CONCLUSION: ¹²³I-OxLDL was widely distributed not only in the liver, but also throughout the whole body, providing insight into the pathophysiological effects of oxLDL.
