ABSTRACT
Introduction. Traffic police in Kathmandu are continuously exposed to air pollution and are at an increased health risk. This study aimed to assess the knowledge and practice regarding prevention of respiratory problems among traffic police in Kathmandu. Methods. A descriptive exploratory study was conducted among the traffic police (n = 83) working in six areas of the Kathmandu Metropolis from July to August 2013. Self-administered questionnaires were distributed to all the participants. Results. The mean age (±SD) of the respondents was 28.8 ± 4.3 years. More than half of the respondents had 6-10 years of work experience, the mean (±SD) years of experience being 7.9 (±3.6). The level of knowledge regarding the prevention of respiratory problems was better than the level of practice among the respondents. Education of the participants did not affect the level of practice of the respondents while there was association between working experience and level of practice (p = 0.04). Conclusion. Since the preventive practice is poor, the government should come up with plans such as distribution of antipollution masks to improve the level of practice among traffic police to prevent respiratory problems.
ABSTRACT
Metastatic tumors of the oral cavity are rare, representing about 1% of oral tumors. Seventy percent of all tumors metastatic to the oral and maxillofacial region are adenocarcinomas, most commonly originating from the breast, kidney and lung. Carcinoma of stomach is generally described as one of the "captains of men of death". Usual sites of metastasis from gastric adenocarcinoma are direct invasion of adjacent organs, peritoneal dissemination, lymphatic metastasis and hematogenous spread. A primary carcinoma of the stomach may rarely metastasize to the oral cavity, it is important to bear this possibility in mind because such conditions may mimic a benign disease. This article describes a case of metastasis of gastric adenocarcinoma to the maxilla in a 50-year-old male.
