The short wave diathermy was utilized on the 25 patients with rheumatoid arthritis suffering from the pain of the knee joint and therapeutic effects were evaluated.
Ito rator K-I, a short wave generator for the treatment at home (voltage: 100v, 28MHZ), was applied on the painful knee joint daily for 20 minutes.
The therapeutic effects were assessed by the findings before and after daily single application of the short wave diathermy (I), and also by the findings after a series of the treatments during a month (II).
In the latter case, the short wave diathermy was utilized for 20 minutes every morning between nine and ten except on Sundays.
For the purpose of the evaluation of the therapeutic effects, six items of the studies were selected, including (1) points of the joint pain, (2) A-ROM of the knee flexion, (3) gait time for 10 meters, (4) time between the flexion and extension, (5) extensor muscle strength of the knee, and (6) flexor muscle strength of the knee.
The results were as follows:
(1) The knee joint pain was improved after daily single application of the short wave diathermy and the decrease in their pain points was 30 per cent.
(2) Gait time for 10 meters and time between the knee flexion and extension (10 times) were significantly improved after daily single application of the short wave diathermy.
(3) After a series of treatments of thort wave diathermy during a month some improvements were showed on the all items, but every improvements was not significant.

In 2013, the fifth Tokyo International Conference on African Development (TICAD V) will be hosted by the Japanese government. TICAD, which has been held every five years, has played a catalytic role in African policy dialogue and a leading role in promoting the human security approach (HSA). We review the development of the HSA in the TICAD dialogue on health agendas and recommend TICAD’s role in the integration of the HSA beyond the 2015 agenda. While health was not the main agenda in TICAD I and II, the importance of primary health care, and the development of regional health systems was noted in TICAD III. In 2008, when Japan hosted both the G8 summit and TICAD IV, the Takemi Working Group developed strong momentum for health in Africa. Their policy dialogues on global health in Sub-Saharan Africa incubated several recommendations highlighting HSA and health system strengthening (HSS). HSA is relevant to HSS because it focuses on individuals and communities. It has two mutually reinforcing strategies, a top-down approach by central or local governments (protection) and a bottom-up approach by individuals and communities (empowerment). The “Yokohama Action Plan,” which promotes HSA was welcomed by the TICAD IV member countries. Universal health coverage (UHC) is a major candidate for the post-2015 agenda recommended by the World Health Organization. We expect UHC to provide a more balanced approach between specific disease focus and system-based solutions. Japan’s global health policy is coherent with HSA because human security can be the basis of UHC-compatible HSS.

Six (1.2%) of 501 patients sustained phrenic nerve injury during operation for congenital heart disease at our institutions between 1992 and 1998. The diagnosis was confirmed by percutaneous stimulation of the phrenic nerve. All but 1 patient were less than 9 months old, and the average weight was 3.6kg. All 6 patients underwent diaphragmatic plication and were extubated by 7 days after operation. Percutaneous stimulation of the phrenic nerve allowed direct assessment of phrenic nerve function which was difficult to detect by clinical and radiological evidence. This method can be non-invasively used at the bedside to facilitate early and accurate diagnosis of phrenic nerve palsy.

In this study, we demonstrated that immobilized fibronectin (FN) enhanced LAK activity, and that the enhanced LAK activity was completely abrogated by an anti-VLA-5 monoclonal antibody and RGD peptide. Fresh -spleen cells expressed VLA-4, VLA-6 and vitronectin receptor, whereas VLA-5 was expressed only on the spleen cells activated with IL-2. LAK cells showed increased adhesion to immobilized FN compared with that to control BSA, and the increased adhesion of LAK cells to immobilized FN was inhibited by anti-VLA-5 monoclonal antibody. Conjugate-formation assay showed that the LAK cells cultured on immobilized FN bound to target cells more efficiently than the control LAK cells, and that anti-LFA-1 monoclonal antibody inhibited the LAK-target cell binding. Immobilized type IV collagen and laminin, as well as FN, enhanced LAK activity. All these results suggest that the interaction of inte-grins expressed on LAK cells with extracellular matrix proteins act as co-stimulator for the enhancement of LAK activity , and that anchorage is necessary for full activation of LAK cells.

Background: We investigated how individual home care services by nurses, care workers, and therapists at patients' homes are related with the continuation of home medical care service provided by medical doctors.Methods: This research retrospectively analyzed primary insured patients registered with the Japanese long-term care insurance system who had newly started using home medical care service, and whose care level was between 1 and 5 according to national long-term care insurance system claims data. We performed multivariable logistic regression analysis to evaluate patients who used home medical care continuously for >3 months and the utilization of each home care service adjusted for patient age, gender, and care level.Results: A total of 26,590 patients were analyzed. Multivariable analysis revealed that the following home care services were associated with longer continuation of home medical care service compared with home medical care alone: day service (OR, 2.10; 95% CI, 1.98-2.23), home help service (1.91; 1.81-2.01), day care including rehabilitation (1.88; 1.69-2.10), home-visit rehabilitation (1.49; 1.31-1.69), and home-visit nursing (1.23; 1.16-1.31).Conclusions: Our results demonstrated a correlation between utilization of home care services and longer continuation of home medical care from the start. These findings may help medical doctors who provide home medical care service collaborate with other home care services by nurses, care workers, and in-home care therapists.

Microvascular free flap transfers have become a preferred reconstructive technique; however, rare complications may still prove devastating. This study reviewed 213 consecutive free-tissue transfers in order to assess the incidence and causes of complications in patients undergoing microvascular free flap reconstruction in the oral and maxillofacial region. In most cases, reconstruction was undertaken after resection of a malignant tumor. The flap donor sites were the radial forearm (n=111), rectus abdominis (n=88), scapula (n=13), and latissimus dorsi (n=1). The superior thyroid artery and the external jugular vein were commonly used as recipient vessels for anastomosis. The overall flap success rate was 99%. There were 7 cases of postoperative vascular thrombosis (6 venous and 1 arterial), constituting 3.3% of the entire series. Five flaps were salvaged, representing a 71.4% successful salvage rate in cases of vascular complications. Most of the successful salvage attempts were made within 24 hours of the end of the initial operation, and the successful salvage rate for re-exploration was 100%. Finally, the total flap loss rate was 0.9% and the partial flap loss rate was 2.3%. We conclude that early re-exploration should be the first choice for management of vascular compromised flaps. Complications at the donor site occurred in 17 cases (8.0%), the most common complication of which was partial skin graft loss after harvesting a radial forearm flap (n=10; 9.0%). Recipient and donor site morbidity was limited and considered acceptable.

We have continued a study on the preventive effects of acupuncture on recurrent tonsillitis. Among 239 patients with tonsillitis examined in 1980, 200 were included in the category of recurrent tonsillitis, showing a fever four or more times a year.
The preventive effects of acupuncture in these 200 patients are reported in this paper.
The subjects were 200 patients with recurrent tonsillitis treated in our department in 1980. The frequency, number of days and severity of fever and other symptoms (conditions of the nose and throat, snoring, colds and general condition) were followed for one year after the acupuncture treatment.
Of the 200 patients, 171, excluding the 29 in whom the results of research could not be obtained, were analyzed. With regard to the frequency of fever, the number of patients with a fever 12 or more times a year decreased from 102 before acupuncture therapy to nine after the treatment. The number of patients who did not have any fever and who had a fever one to three times after treatment was 30 and 69, respectively. Thus, 40.4% were not included in the category of recurrent tonsillitis, even though fever was present. In addition, there was a decrease in the severity and number of days of fever.
Favorable effects of the treatment on symptoms other than fever, such as conditions of the nose and throat, snoring, resistance to colds and general condition, were noted in more than 50% of the patients who did not have any fever after treatment or had a fever half as frequently as before treatment.
When the preventive effects on fever were determined according to age, improvement was observed in all age groups. From the viewpoint of the prevention of repetition of a high fever, the best results were obtained in patients 6-11 years of age, followed by those five years old or less.
Acupuncture treatment for recurrent tonsillitis is not so effective as tonsillectomy. However, we consider that acupuncture treatment is worth using prior to tonsillectomy to prevent the relapse of recurrent tonsillitis, taking into account operative stress on the living body and economic and personal problems arising from tonsillectomy.

Maximal oxygen uptake (Vo₂max) and lactate threshold were measured during an incremental bicycle ergometer test in 40 healthy middle-aged and older runners between 43 and 79 years of age. Although the 10-km run time slowed with increasing age, there were no significant differences in recent training habits or relative amount of body fat between four age groups. However, our cross-sectional data revealed an annual decrement of -0.74 ml/kg/ min/yr, which was significantly greater than that reported in previous studies. Vo₂max values for the runners were greater than those for sedentary men of similar ages by about 50% in each age group. Significant correlations were found between the age at the onset of running training and Vo₂max (r=-0.600, p<0.05) . Vo₂@LT declined significantly but less rapidly with age (r=0.686, p<0.05) than Vo₂max. Both the mean maximal heart rate (HRmax) and HR@LT also declined with age. No significant differences in HRmax were observed between the runners and sedentary men of the respective age groups. Significant correlations were also found between the estimated HRmax and directly measured HRmax (r=0.600) . Neither systolic blood pressure nor diastolic blood pressure during submaximal-maximal exercise were found to increase with age. We suggest that maintenance of a higher lactate threshold in older runners when expressed as a percentage of Vo₂max is attributable to a greater age-dependent decline in Vo₂max with a smaller change in Vo₂@LT.

We have conducted acupuncture treatment for prevening the relapse of recurrent tonsillitis. We previously noted the effectiveness of this treatment in 121 of 239 patients treated in 1980, especially in elementary school children. In the present study, we compared the annual days of absence from school and the body dimensions of children with tonsillitis given acupuncture treatment with those having tonsillar hypertrophy chosen by a school study, although there is a question on the latter's propriety as a control group in a strict sense, in order to investigate the degree of spontaneous healing included in the preventive effects of acupuncture treatment on the relapse of recurrent tonsillitis.
By May 1983, our reseach was completed in 22 children with tonsillitis given acupuncture treatment and 19 with tonsillar hypertrophy not given such therapy. In children with tonsillitis given acupuncture treatment, the average annual days of absence from school before treatment was 14.0, which was more than that for all children in the S elementary school, and that in the year after treatment was 6.5, approximating that for all children in the school. In children with tonsillar hypertrophy not given acupuncture treatment, the average number of days of absence was close to that for all children in the S elementary school in both years.
Among 14 children with tonsillitis given acupuncture treatment, lower values of height and weight were noted in eight and 12 children, respectively, at the beginning of treatment, as compared with the national averages. The body dimensions of children with tonsillar hypertrophy not given acupuncture treatment were similar to the national averages. Of 14 children with tonsillitis given acupuncture treatment, an increase to a value exceeding the national average was observed with both the height and weight in six children, the height in two and the weight in one within the year after treatment.
The above results show that children with tonsillitis have a problem from the educational and developmental standpoint, even if they do not have a focal tonsil. We think that acupuncture treatment is worth attempting prior to tonsillectomy, although it is not so surely effective as tonsillectomy, when the severity of operative stress on the living body due to tonsillectomy and the burden of medical expenses and the load on the patient's family caused by hospitalization are taken into consideration.

Objective: The practices pertaining to hereditary breast and ovarian cancer (HBOC) in Japan have been rapidly changing owing to the clinical development of poly(ADP-ribose) polymerase inhibitors, the increasing availability of companion diagnostics, and the broadened insurance coverage of HBOC management from April 2020. A questionnaire of gynecologic oncologists was conducted to understand the current status and to promote the widespread standardization of future HBOC management. Methods: A Google Form questionnaire was administered to the members of the Japan Society of Gynecologic Oncology. The survey consisted of 25 questions in 4 categories: respondent demographics, HBOC management experience, insurance coverage of HBOC management, and educational opportunities related to HBOC. Results: A total of 666 valid responses were received. Regarding the prevalence of HBOC practice, the majority of physicians responded in the negative and required human resources, information sharing and educational opportunities, and expanded insurance coverage to adopt and improve HBOC practice. Most physicians were not satisfied with the educational opportunities provided so far, and further expansion was desired. They remarked on the psychological burdens of many HBOC managements. Physicians reported these burdens could be alleviated by securing sufficient time to engage in HBOC management, creating easy-to-understand explanatory material for patients, collaboration with specialists in genetic medicine, and educational opportunities. Conclusion Gynecologic oncologists in Japan are struggling to deal with psychological burdens in HBOC practice. To promote the clinical practice of HBOC management, there is an urgent need to strengthen human resources and improve educational opportunities, and expand insurance coverage for HBOC management.
