Introduction
 On 8 March 2009, the Workshop on Infectious Diseases Control Programmes and Health System Strengthening (HSS) was conducted in the 24th East Japan Regional Conference of the Japan Association for International Health. This article reports the discussion in the Workshop and the internet-based open forum that followed.
Method
  After four presentations reflecting on the field-based experiences regarding the relation between disease-specific programmes and HSS, following three aspects were discussed: 1) health system-wide barriers perceived through the implementation of disease-specific programmes; 2) shortcomings of the disease-specific initiatives in light of the HSS; and 3) how the disease-specific initiatives can contribute to the HSS.
Results
 As the system-wide barriers, insufficient quantity and quality of health human resources, lack of health infrastructure and material resources and limitation of the technology applicable to community level of developing countries were commonly perceived. Shortfall of disease-specific programmes in light of the HSS included the lacked coordination between different programmes and donors, duplicated heavy workload put on community health workers especially in recording and reporting, dissociation between local health needs and programme priorities, lack of contributions to strengthening mid-level health administration, deviation of resources to the priority programmes and lack of sharing of potentially sharable material resources. It was proposed that the disease-specific initiatives should contribute to resource mobilization, programme management models, capacity building of mid-level health administration, supplementing personnel cost and presenting hardware and software outcome resources to the HSS.
Conclusions
 The disease-specific initiatives need to pursue the above mentioned practical contributions to the HSS. At the same time, a wider scope addressing political and policy-wise justifications of the form of the overall health system needs to be further discussed with developing countries stakeholders.

A 63-year-old man had undergone patch repair of a chronic dissecting thoracoabdominal aortic aneurysm 8 years previously. Postoperative course was uneventful during 8 years after the first operation. However follow-up CT scan 8 years after demonstrated pseudoaneurysm of thoracoabdominal aorta at the anastomotic side. Reoperation for pseudoaneurysm was performed through left thoracotomy under partial cardiopulmonary bypass. Pseudoaneurysm was revealed at the proximal anastomotic side. Graft replacement for thoracoabdominal aorta and reconstruction of two pairs of intercostal arteries and the celiac artery was performed under SEP and MEP monitoring. His postoperative course was uneventful. He was discharged from our hospital 12 days after surgery. Follow-up CT scan demonstrates no recurrence of pseudoaneurysm for 1 year after surgery.

The 2009 pandemic of novel swine-origin influenza A (H1N1) highlighted the importance of community mitigation measures such as voluntary isolation. During the pandemic, we investigated the voluntary isolation behavior of patients with influenza during the 7-day period after they visited an outpatient clinic at a hospital in Tokyo, Japan. A questionnaire-based survey was conducted on patients diagnosed with influenza. Of a total of 14 patients, 13 (93%) visited a workplace, school or other potentially crowded setting at least once in the 7-day period after presentation. Five patients (36%) visited a potentially crowded setting either with a fever or on the day after having a fever. The voluntary isolation behavior of Japanese people with influenza did not necessarily adhere to the Japanese government recommendation that people with influenza-like illness stay home for 7 days following the onset of symptoms.

A 11-year-old boy was admitted to our hospital with a diagnosis of the progressive residual coarctation of the aorta, severe left ventricular hypertrophy and dilatation of the ascending aorta. He had previously undergone 3 operations for coarctation of the aorta. We performed ascending-to-descending aortic bypass through a median sternotomy for residual coarctation of the aorta. Partial cardiopulmonary bypass (CPB) was established via the right femoral artery and right atrium. A cephalad retraction of the heart with a heart positioner and a longitudinal pericardial incision over the descending aorta allowed excellent exposure of the aorta through the posterior pericardium. The graft was anastomosed to the ascending aorta and descending aorta. The graft was brought around the right lateral aspect of the right atrium and through to the anterior aspect of right pulmonary veins and inferior vena cava. The bypass graft size was 14 mm in diameter. The CPB time was 134 min, and operation time was 232 min. The postoperative course was uneventful, and he did not suffer from paraplegia. His blood pressure postoperatively normalized without medication. He was discharged 20 days after surgery. The ascending-descending aortic bypass through a posterior pericardium approach is a safe and effective option for relieving residual coarctation and improving hypertension, for patients who have complex coarctation requiring surgical correction. However, because of his young age (II) it is necessary to follow him up carefully.

In Lao PDR, the National Malaria Control Program (NMCP) evaluates bednet coverage, often at the village level, using a coverage target of one net per 2.5 (or fewer) persons in a given population. However, in villages that meet the target, not all households necessarily meet the target or utilize all available bednets. This study explored households that fell short of the target and household utilization of bednets in villages that met the target of bednet coverage set by the NMCP. The person per net ratio (PPNR), which is defined as the population divided by the number of available bednets in a household/village, was used to determine whether a household/village met the NMCP target. Using a household survey, we collected and analyzed the data of 635 households in 17 villages in Xepon district in 2012. Households that fell short of the target (households with a PPNR of > 2.5 or no bednet) existed in every village. The proportion of these households differed greatly among the villages, ranging from 3.4–50%, with some households falling far short. Of the 635 households, 275 (43.5%) had at least one bednet that was not being used on the night preceding the survey and 131 (20.6%) had at least two. In conclusion, in villages that met the NMCP target, a considerable number of households fell short of the target, and the available bednets were not fully utilized in many of the surveyed households.

PURPOSE: The purpose of this retrospective study was to determine the effects of resistance training (RT) on myocardial infarction (MI) patients in phase II cardiac rehabilitation (CR) in our hospital.
METHODS: Twenty two outpatients who had participated in the phase II CR program more than three months at least were enrolled in this study. They were divided into control group (n＝8) and RT group (n＝14). We examined changes in the exercise capacity of these two groups. The traditional exercise programs which included aerobics and muscle strength exercise were run on the control group. Changes in exercise load for target heart rate measured with a bicycle ergometer as an indicator of exercise capacity were assessed in each patient 1,3 and 5 months after AMI onset.
RESULTS: The amounts of load and target heart rates recorded 1 month after the onset were not significantly different between the two groups. After 3,5 months of CR, the RT group showed no changes in the target heart rate but significant increase of the amount of load. The control group showed no change in the amount of load and target heart rate. In the amount of each load 3 and 5 months after, the RT group was significantly out did the control group.
CONCLUSIONS: These results suggested that RT was useful in the improvement of exercise capacity for patients with MI who participated in the phase II CR program provided by our hospital.

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.
