The purpose of this study was to investigate the causes of food impaction and to explore solutions as well. For this study, 39 patients with food impaction wee selected. 77 contact areas in these patients were investigated mobility, tightness of contact area, gingival index, plaque index, attachment loss, alveolar bone loss, proximal caries, marginal ridge distance and occlusal relationships. The results were as follows ; 1. Teeth without distal support were found to be the most frequent site of food impaction (41.6%). Food impaction was found to be more frequent in the upper teeth (66.2%) than the lower teeth (33.8%). 2. Food impaction was found in tight contact cases (71.4%). Alveolar bone loss was not found in the early stage of food impaction (83.1%) 3. The distance between the marginal ridges of food impaction sites (mean=0.48mm) was shorter than that of the control group. (mean=0.77mm) (p<0.001) 4. In 18.2% of t he cases, proximal carries were found at the food impaction site. 5. Food impaction affected patient's occlusion with the following frequencies ; cusp to marginal ridge relationship (72.7%), cusp to fossa relationship (3.9%) and stepped relationship (23.4%).

A polymerase chain reaction (PCR) method for detection of the pathogenic Yersinia pestis from other Yersinia spp. was developed. Five Y. pestis strains, ninety-two other Yersinia species and twenty-four Enterobacteriaceae strains were collected in Korea and from other countries. Oligonucleotide primers were designed from pathogenic gene of antiphagocytic protein capsule gene (fra 1) and plasminogen activator gene (pla). The 428 bp DNA fragment was amplified from five Y. pestis which contained the fra I gene. No product was amplified from other Yersinia species and other strains of the Enterobacteriaceae. The 439 bp DNA fragment was amplified from three K pestis which contained the pla gene. No product was amplified from two Y. pestis, other Yersinia species and other strains of the Enterobacteriaceae. These showed that the designed primers were specific for detection of Y. pestis among other Yersinia species and Enterobacteriaceae strains. Amplification was successful whether the template was derived from purified DNA or from aliquots of boiled bacterial suspension. The detection limits were 100 pg of DNA and 100 colony forming units (CFU) for fra I and 100 pg DNA and 10 CFU for pla, respectively. Our results prove that the PCR method using specific primers for Y. pestis is a rapid and convenient procedure for routine clinical detection and identification of Y. pestis.

Coronavirus disease (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 has become a global pandemic and is now the most threatening public health issue. Patients with the infection present with high fever and pneumonia with respiratory symptoms, but some patients also develop digestive symptoms such as diarrhea, vomiting, and abdominal pain. This may be the basis for the transmission route of the new virus, not only for respiratory infection through droplets but also for fecal-to-oral transmission. In addition, the high expression level of angiotensin-converting enzyme 2 on the surface cells in the gastrointestinal tract may support the occurrence of digestive symptoms and the possibility of fecal-to-oral transmission. Recent studies have shown positive fecal polymerase chain reaction (PCR) test results in patients with the infection who showed digestive symptoms. Therefore, we reviewed the related literature on the occurrence of digestive symptoms in patients with COVID-19 and present the usefulness and clinical application of the fecal PCR test for identifying the potential infection route and criteria for isolation.
