Three patients, who received infrarenal aorto-iliac bifurcation grafts, complained of flaccid and insensible feeling on lower extremities immediatedly after surgery. These symptoms were supposed due, in two cases, to spinal cord ischemia or, in remaining one case, to ischemic change of the peripheral nerve, In former cases, spinal cord hypoxia might be caused by interrupted blood supply through spinal artery as it was intercepted temporarily but for about three and a half hours during surgical procedures. In the latter case, cramping of the left iliac artery lasted for five and a half hours, which might result in anoxic damage of the peripheral nerve. Hyperbaric oxygenation (HBO) at two atmospheric absolute (ATA) pressure for 75min and 3 ATA for 90min were repeated everyday for them. In all cases, almost complete sensorimotor recovery was obtained after 15 to 30 instances of HBO, which was combined with physical therapy. HBO seemed to have improved early hypoxic and edematous damages of the spinal cord or peripheral nerve. As an unfavorable complication of abdominal aortic surgery, incidence of sensorimotor disturbance of the extremities is infrequent and/or unpredictable, however, once it occurs, no effective therapeutic maneuvers were developed yet. Through these clinical data, HBO should be introduced more actively for such disorders. One of the key issues to enhance the effect of HBO is that, HBO should be introduced as soon as possible once postoperative nuerologic disorders were diagnosed.

Although there are a number of reported cases of increased cerebral blood flow during exercise, there are no reports on the relation between changes of blood flow during exercise and attentional function. The purpose of this study is to clarify the relation between changes of blood flow during exercise with AT intensity and attentional function, using near-infrared spectral analysis. The subjects were 10 healthy males. The research protocol was to conduct steady load exercise. We randomly conducted two invention trials: 1) an exercise/task trial in which a trail making test (TMT) was performed as an attentional assignment during steady load exercise, and 2) a rest/task trial in which TMT was performed during rest as a control. As a result, we observed the following: increase of oxy-Hb in the prefrontal cortex during AT exercise, the significant shortening of TMT during exercise from 69.1±10.2 seconds to63.2±7.2seconds, and, with further control, that the more oxy-Hb rises, the more TMT time is shortened. From these results, it is suggested that 10 minutes of exercise would improve attentional function, and furthermore, there is a possibility that increased cerebral blood flow may be involved with the improvement of attentional function.

In Niger, insecticide-treated bed nets (ITNs) have been distributed to the target group of households with young children and/or pregnant women at healthcare facilities in the course of antenatal/immunization clinics. With the aim of universal coverage, ITNs were additionally distributed to households through strengthened community health committees in 2009. This study assessed the impact of the community-based net distribution strategy involving community health committees in the ITN coverage in Boboye Health District, Niger. A cross-sectional survey was carried out on 1,034 households drawn from the intervention area (the co-existence of the community-based system together with the facility-based system) and the control area (the facility-based system alone). In the intervention area, 55.8% of households owned ITNs delivered through the community-based system, and 29.6% of households exclusively owned ITNs obtained through the community-based system. The community-based system not only reached households within the target group (54.6% ownership) but also those without (59.1% ownership). Overall, household ITN ownership was significantly higher in the intervention area than in the control area (82.5% vs. 60.7%). In combination, the community-based system and the facility-based system achieved a high ITN coverage. The community-based system contributed to reducing leakage in the facility-based system.

Although long-lasting insecticide-treated bednets (LLINs) have been widely used for malaria control, little is known about how the condition of LLINs affects the risk of malaria infection. The objective of this cross-sectional study was to examine the association between the use of LLINs with holes and caregiver-reported malaria diagnosed in children under five years of age (U5). Data were collected in Boboye health district, Niger, in 2010. Surveyors conducted interviews and bednet inspections in 1,034 households. If a household had a U5 child, the surveyor asked the caregiver whether the child had experienced a fever episode in the past two weeks that entailed standard treatment for uncomplicated malaria at a healthcare facility. The authors analyzed the association between the use of LLINs with holes and caregiver-reported malaria episodes in U5 children using logistic regression, adjusted for possible confounders. Of the 1,165 children included in the analysis, approximately half (53.3%) used an intact LLIN while far fewer (10.6%) used a LLIN with holes. Compared to children using an intact LLIN, children using a LLIN with holes were significantly more likely to have a caregiver-reported malaria episode (8.7% vs. 17.1%; odds ratio: 2.23; 95% confidence interval: 1.24–4.01). In this study site, LLINs with holes were less protective than intact LLINs.

Purpose: Although patients with late-onset hypogonadism (LOH) often experience lower urinary tract symptoms (LUTS), LUTS are not generally included in LOH symptoms. No study has examined the direct relation of the Aging Males Symptoms rating scale (AMS) and the International Prostate Symptom Score (IPSS) with the quality of life (QOL) index. We analyzed the relation between the IPSS and QOL index and various factors including the AMS in patients with LOH syndromes. Materials and Methods: This study comprised 1,688 men with LOH symptoms who visited our hospital or affiliated clinic. Factors associated with the IPSS were assessed in terms of age, scores of several questionnaires including the AMS, endocrinological variables, and serum concentration of PSA. Among these same factors, those associated with the QOL index were also evaluated. Finally, the same analyses were repeated in 187 patients with low serum testosterone concentration (<3.0 ng/ mL). Results: In a multivariate analysis using the significant items from the univariate analysis, AMS, age, and Erection Hardness Score correlated significantly with the IPSS. A trend analysis using items other than the AMS as adjustment factors also confirmed the relationship between an increase in QOL index and an increase in AMS. Similar results were obtained in the analysis of patients with low serum testosterone concentration. Conclusions We revealed that the relation of IPSS with the QOL index for LUTS is closely associated with the AMS for LOH, regardless of testosterone level. When patients complain of LOH symptoms, a careful, detailed inquiry into LUTS is required.

We investigated the actual condition of patients treated by acupuncture and moxibution in Ibaragi Prefecture.
Subjects were 1823 patients (846 men, 977 women) under the treatment of 14 acupuncture clinics in September to November, 1985.
We prepared the evaluated list that consisted of 11 levels of activities of daily life and 8 degrees of pain.
In every treatment, we wrote down the patient's clinical progress in relation with the list.
The following results were obtained
1. There were many patients in thier forties and fifties.
2. There were many patients who received only one treatment.
3. The chief complaints were low back pains (509 patients), shoulder discomfort (273) knee joint pain (132), etc.
4. Most of the patients could still go on with thier daily lives in spite of the pains.
5. The effects of treatment were rated as follows; better 69.5%, no change 23.9%, worse 5.9%.
