The primary school-based helminthiasis control project was carried out in 767 communes (39 districts of 11 provinces). It is a combinate of IEC activities and periodical deworming every 6 months with mebendazole 500mg. 1,217,754 school children times (in 1,146 primary schools) have been drug administrated, coverage 97.2% - 100%. Side effects were not high 0.03% - 0.29%. Stool examinations have shown that the prevalence of infection is 98.4% - 78.8% and 19.2% respectively in the North, Center and the South. The intensity of Ascaris, Trichuris and hookworm infection in almost of schools is not rather high. The KAP surveys have shown that the majority of school children and their parents have knowledges of the reasons and the complications of helminthiasis 62.3% - 80.5% and 99.0%. However, percentage of people using nightsoil as fertilizer is 10.3%

Journal of Korean Neurosurgical Society 2006;39(2):144-147
Rhabdoid meningioma is an uncommon meningioma variant, which was initially described in 1998 by Perry et al.. It is classified as a variant corresponding to grade III in the recent World Health Organization(WHO) classification of tumors of the nervous system, because of its unique histopathological features and its highly aggressive clinical course. To date there were still a lot of arguments about their developmental patterns and the treatment strategy especially for rhabdoid meningiomas lacking other histological features of malignancy. Although the exact causes of rhabdoid transformation of a benign meningioma are unknown, malignant transformation long duration after surgical resection under an underlying predilection for malignancy is suggested in our case. And we suggest that any histological rhabdoid features in recurrent meningiomas or even in primary cases seem to indicate the malignant clinical course and the need for aggressive treatments, because transformation from a benign or atypical one to a malignant one seems to occur at last.

BACKGROUND/AIMS: Several criteria have been proposed to increase the objectivity, reliability and validity of causality assessment of adverse drug reactions (ADR). We compared the Naranjo probability scale and the World Health Organization-Uppsala Monitoring Centre (WHO-UMC) causality categories to evaluate the validity and clinical usefulness of these criteria. METHODS: We evaluated 100 ADR cases with the Naranjo probability scale and the WHO-UMC causality categories. The Spearman rank coefficient was used to determine the correlation of these criteria. The evaluation of the ADR was categorized into four groups for the Naranjo system: definite, probable, possible, and doubtful, and six groups for the WHO UMC: certain, probable, possible, unlikely, conditional/unclassified, and unassessable. RESULTS: The criteria used form these two systems showed some differences when compared with the same ADR cases. The Spearman rank coefficient was 0.519 (p<0.001) and the agreement was 55% between the Naranjo probability scale and the WHO-UMC causality categories. The Naranjo probability scale includes measurements for drug concentration, objective evidence of ADR, ADR to previous exposures, responses to placebo, and the dose adjustment of drugs. However, few cases were evaluated for all of these measures. CONCLUSIONS: The Naranjo probability scale may be helpful for assessing unexpected ADRs and useful for evaluators with little experience. However, some of the items are not utilized and there are discrepancies when compared with the WHO-UMC causality criteria.

7.Changing Concepts and Classifications of Disablement.
Journal of the Korean Medical Association 2009;52(6):537-544
In spite of a refined classification on the functioning or disability accredited by World Health Organization (WHO, 2001), explicit concepts or definitions of health, disablement and its related terminologies of impairment, disability, handicap, activity limitation and participation restriction are generating considerable confusion in Korea. It is very important to understand the new concepts of these different changing terms in all health related fields. International Statistical Classification of Diseases and Related Health Problems (ICD-10) has reported diagnosis or mortality statistics, but the report did not cover the health status of living populations or information about non-fatal health outcomes. In order to rectify this situation, WHO developed a new tool for the classification of the consequences of disease, namely the International Classification of Impairments, Disabilities and Handicaps (ICIDH) in 1980. Following several revisions, WHO announced the International Classification of Functioning, Disability and Health (ICF) in 2001, which was not based on a medical or a social model, rather on bio-psycho-social and interactive model. WHO recommend the use of the two different classifications to provide relevant and updated information on diagnosis of disease (s) with ICD-10 and also on assessment of functioning or disability with ICF.

9.Assessment of the Cardiovascular Risk of Persons with Hypertension and Diabetes Attending Clinics and Hypertension/Health Club Meetings in the AMIGA Municipalities of Cavite, Philippines using WHO/ISH Risk Prediction Charts
Acta Medica Philippina 2020;54(5):536-545
Objectives:
This study aims to (1) determine the cardiovascular risk of persons with hypertension and diabetes attending hypertension/diabetic clinics or hypertension/health club meetings in the AMIGA (Alfonso, Mendez, Indang, General Emilio Aguinaldo and Amadeo) municipalities of Cavite; (2) suggest measures to improve the cardiovascular disease (CVD) program in these municipalities using the results of the study.
Methods:
A cross-sectional study was performed on patients diagnosed with hypertension and/or diabetes who are attending clinics or club meetings in the barangays of the five AMIGA municipalities of Cavite. Participants were interviewed using an abbreviated version of the World Health Organization (WHO) STEPS questionnaire on risk factors. The participants’ anthropometric measurements were obtained and their total blood cholesterol levels determined. CVD risk was then estimated using the WHO / International Society of Hypertension (ISH) risk prediction chart for the Western Pacific Region B.
Results:
1,032 participants from 27 barangays qualified for the study. Participants were predominantly female (74%); over-all mean age was 58.43 years. The majority of the participants (79.17%) were found to be in the low-risk group; 11.34% were in the moderate risk group; 4.46% were in the high-risk group; while 5.05% were in the very high-risk group. Majority of the participants were also found to be obese. Mean total cholesterol was 207.02 mg/dl.
Conclusion
Majority of participants were stratified in the low-risk category (<10% chance to have cardiovascularevents in the next 10 years), while 9.5% were in the high-risk category (≥20% risk). Obesity is a major risk factor that could be addressed in this population.

Various benign and malignant mesenchymal tumors can occur in the breast. Most radiologists are unfamiliar with the imaging features of these tumors and the imaging features have not been described in the radiologic literature. It is important that radiologists should be familiar with the broad spectrum of imaging features of rare mesenchymal breast tumors. In this pictorial review, we demonstrate the sonographic findings and the corresponding pathologic findings of various mesenchymal tumors of the breast as defined by the World Health Organization classification system.
