Between June 1998 and January 2000, "The Master Plan Study on Strengthening Primary Health Care Services (JICA PHC Study)" was executed in the Republic of Malawi. The purpose of the study was to formulate a central region master plan and a national master plan to improve the primary health care (PHC) system, and to transfer essential research, analytical skills, and methodologies to Malawian counterparts. The health investigations covered the referral system, human resources, health finance, policy and management, the health management information system, community participation, logistics systems and health facilities and supplies. As a result of the study, childhood malnutrition, maternal health, and the inappropriate role of informal drug-sellers, in the PHC system were found to be key health issues, and on the basis of these problems the national master plan was formulated with six prioritized proposed projects. In this report, the following challenges to the execution of effective and efficient study were discussed and recommended through the review of health development studies conducted in five developing countries including Malawi; 1) the study purpose and the concept of a master plan should be clarified, 2) the study outcome should be evaluated and utilized effectively, 3) terms of reference for the study should be reviewed and improved, 4) a better relationship with counterparts and donors should be developed, and 5) a capacity of participants in the study such as consultants should be built up.

A 53-year-old woman with atrial septal defect (ASD) and atrial fibrillation (AF) with idiopathic thrombocytopenic purpura (ITP), was scheduled to undergo ASD closure and the maze procedure. Because steroid therapy was not effective, high-dose γ-globulin administration (400mg/kg/day) was performed for 5 days before surgery. The platelet count increased from 5.4×10⁴/mm³ to 14.0×1⁴/mm³. ASD patch closure and modified bilateral appendage preserving (BAP) maze procedure were performed. No hemorrhagic tendency was recognized. The postoperative course was uneventful, and the sinus rhythm was recovered. The maze procedure become possible in this ITP patient with preoperative administration of high-dose γ-globulin.

The research project titled “Developing Technical Approaches for the Master Plan of the Health Sector International Cooperation ” has been conducted for the duration of three years from 2002 by the support of grants-in-aid for research on international medical cooperation from the Japanese Ministry of Health, Labor and Welfare. Based upon comprehensive and detailed review on the development studies (DS) in the health sectors so far completed, and throughout extensive and detailed examinations on the various DS related issues at the organized workshops with the parties concerned, the following propositions were made for the orientation and possible improvement of future DS in the health sectors; 1) a master plan in the individual DS to be defined in association with the level of strategy with which the study deals, 2) the instruction of surveys and methods to be more crystallized, 3) appropriate survey methods with reproducibility to be employed, 4) qualitative researches to be complimentarily exercised with quantitative researches 5) the ownership of DS to be cultivated by adoption of participatory methods.

Objective: We investigated subjective effects of a lactoferrin (LF) -containing supplement on cold-like symptoms and gastroenteritis symptoms.
Method: Healthy women were divided into a LF-consumption group and a non-consumption group. The former intaked LF-containing tablets for 90 days. Subjects filled out questionnaires about cold-like symptoms, gastroenteritis symptoms, and drug use.
Results: Significant decreases were found in the onset of cold-like symptoms and gastroenteritis symptoms in the LF-consumption group compared with non-consumption group.
Conclusion: These results suggest the possibility that LF intake inhibits the onset of common cold and gastroenteritis.

Garré's osteomyelitis is generally considered to be synonymous with chronic osteomyelitis with proliferative periostitis and occurs most commonly in the first molar region of the mandible. We report a case of Garré's osteomyelitis caused by the infected tooth-germ of a wisdom tooth. A 12-year-old boy had a swelling of the right cheek and his right mandibular second molar was covered by gingiva with pus retention. X-ray examination showed a radiolucent area around the impacted tooth-germ of the wisdom tooth and extracortical new bone at the angle of the mandible. After preoperative treatment with antibiotics, the tooth-germ and extracortical bone were removed. The antibiotics treatment was continued for 18 days postoperation. No recurrence of pain or swelling has been observed thereafter.

The surgical results of 9 patients (group II) who were treated for thoracoabdominal aneurysm using left heart bypass combined with oxygenation were compared to those of 16 patients (group I) using left heart bypass without oxygenation. The left heart bypass time in group II was longer than that in group I, and the operations performed in group II were more extensive with more intercostal and lumbar arteries being reconstructed than those in group I. Nevertheless, bleeding associated with transfusion was less in group II than in group I. Intraoperatively, hypothermia and hypoxemia developed in 44% and 31%, respectively of group I, whereas neither of these conditions occurred in group II. There were three operative deaths in group I, compared with one in group II. Paraplegia was encountered in one patient of group I, but in none of the patients in group II. There were a few patients with respiratory failure or other organ failures in both groups. Our results showed that left heart bypass combined with oxygenation offered more stable and effective respiratory as well as circulatory support for a long duration compared to conventional left heart bypass without oxygenation in the surgical treatment of thoracoabdominal aortic aneurysm.

Introduction
 During the course of primary health care activities in Khammouane province of Lao PDR by non- profit organization, international support and partnership for health, an exceedingly high infant mortality rate was recognized in some villages. As thiamine deficiency was strongly suspected for the main cause of the high mortality, the household survey with an emphasis on nutritional aspect and the measurement of thiamine level in the blood of mothers as well as their breast-milk were carried out for the confirmation.
Methods
 The survey was conducted at Sibounhouane sub-district (Group 1) with the highest infant mortality and Hatkhamhieng sub-district (Group 2) with the lowest mortality. Fifty families of the two groups, each consisting of randomly selected 25 families with less than one year old infant(s) were interviewed by using prepared questionnaire. The body weight of both mother and infant was measured and blood and milk were taken from the mother.
Results
 The ethnic minorities of the group 1 consisted of Lao Lum (44%) and Lao Theung (56%), whereas only Lao Lum in the group 2. The economical indicators and the mother's educational level in the group 1 were inferior to those in the group 2. There was no significant difference in the methods of preparing staple glutinous rice, likely to flux thiamine and intake of thiaminases between the two groups. High infant mortality rate was documented in the group 1 whose clinical symptoms were mostly consistent with those of infantile beriberi. The concentration of thiamine in the blood and milk of mothers in both groups were considerably lower and significant reduction of thiamine level was observed in the group 1 than the group 2. Nevertheless, both groups of those infants tended to be inadequately fed with the foods except for breast-milk during their early infantile phase.
Conclusions
 The low concentration of thiamine in the blood and milk of mothers was strongly suggestive that infantile beriberi due to thiamine deficiency was the principal cause of the infant mortality in the study region. We hereby surmise that thiamine deficiency could be extensively prevalent in Lao PDR than the currently studied areas because of their traditional preparing methods of staple dietary rice, postpartum food taboos and intake of thiaminases. For the prevention of infant death due to severe thiamine deficiency, necessary measures including the exchange of information among the institutions concerned, adequate thiamine supplementation and nutritional counseling have to be urgently adopted.

Striking advances in systemic therapy for unresectable advanced hepatocellular carcinoma (HCC) have improved the average prognosis of patients with HCC. As a result, the guidelines for the treatment of HCC have changed significantly. However, various issues have emerged in clinical practice. First, there is no established biomarker that can predict response to systemic therapy. Second, there is no established treatment regimen after primary systemic therapy, including combined immunotherapy. Third, there is no established treatment regimen for intermediate-stage HCC. These points make the current guidelines ambiguous. In this review, we present the Japanese guidelines for the diagnosis and treatment of HCC based on the latest evidence; introduce various efforts mainly in Japanese real-life practice to update these guidelines; and present our perspectives on future guidelines.

Histiocytic sarcoma in the liver is an extremely rare hematological malignancy. Herein, we reported the case of a 68-year-old woman who presented with characteristic wedge-shaped abnormality bounded by hepatic veins on computed tomography and magnetic resonance imaging of the liver. In the wedge-shaped area, decreased portal flow and the deposition of iron were observed. These imaging findings are consistent with intrasinusoidal tumor cell infiltration. A liver biopsy was performed, and histiocytic sarcoma was confirmed histopathologically.

Objective: To evaluate the efficacy of high-flow nasal cannula oxygen (HFNC) for dyspnea in patients with advanced disease. Methods: A literature search was conducted using MEDLINE, Cochrane Library, EMBASE, and Ichu-shi Web. Inclusion criteria were: 1) randomized controlled trials evaluating the effect of HFNC on dyspnea; 2) aged 18 years or older with advanced disease with hypoxemia; 3) control group was conventional oxygen therapy or noninvasive positive pressure ventilation. Exclusion criteria were: 1) patients in intensive care unit, 2) weaning from ventilator. Results: Six studies (4 from database searches, and 2 from hand searches) were included. In the 2 studies evaluating short-term intervention, one showed HFNC was more efficacious, and the other conventional oxygen was more efficacious. In the 2 studies evaluating long-term interventions: one showed HFNC was more efficacious, and the other showed no significant difference. In the 2 studies evaluating the intervention during exercise, one showed HFNC was more efficacious, and the other showed no significant difference. Conclusion: HFNC may be effective for dyspnea in patients with advanced disease associated with hypoxemia.
