Periodontal disease is one of the most common chronic inflammatory diseases in the oral cavity, and this is the leading cause of loss of teeth. Studies on the association between diet and periodontal diseases are very limited. The purpose of this study was to investigate the association between food and nutrient intakes and the prevalence of periodontitis. Subjects were 13,391 adults participating in the 2008-2010 Korea Health and Nutrition Examination Survey. Periodontitis was diagnosed by dentists using the Community Periodontal Index. Nutrient intakes were estimated by the 24-hour dietary recall. Consumption frequencies of foods were from the food frequency questionnaire. Subjects were categorized into 'smoking' or 'non-smoking' groups. Multiple logistic regression analysis was applied to determine the association between diet and periodontitis. The proportions of subjects having periodontitis were 26% in the non-smoking group and 37.5% in the smoking group. In the non-smoking group, intakes of fruits, dairy products, green tea, energy and vitamin C were inversely associated with the prevalence of periodontitis, but fish and coffee intakes were positively associated with the prevalence of periodontitis after adjusting for covariates. In the smoking group, protein and retinol intakes were inversely associated with the prevalence of periodontitis after adjusting for covariates. These results suggest that certain food and nutrient intakes such as fruits, dairy products, green tea, vitamin C, protein, or retinol intakes may affect the prevalence of periodontitis among Korean adults. Further studies are required to confirm these findings in other research settings.

Genes of cancer-associated testis antigens (CTAs) are expressed in various cancer tissues. In order to use CTAs as cancer diagnosis marker, we developed molecular method for detection of CTAs transcripts in tissue. In order to know the applicability of DNA of cancer-associated testis antigens (CTAs) on cancer diagnosis, molecular diagnostic methods for detection of gene expression of melanoma antigen gene (MAGE), GAGE, and B melanoma antigen (BAGE) was studied. After comparing DNA sequences of CTAs, S1/AS1 and S2/AS2, GAGE-S/ GAGE-AS, and BAGE-S/BAGE-AS primers were designed for the detection of MAGEs, GAGEs and BAGEs, respectively. The gene expression of CTAs in cancer cell lines, head and neck cancer tissues, ovary cancer tissue, and peritoneal cells of gastric cancer patients were investigated by reverse transcription-polymerase chain reaction (RT-PCR) using these primers. The MAGEs, GAGEs and BAGE genes were expressed in 8/8 (100%), 5/8 (62.5%) and 1/8 (12.5%) of head and neck cancer tissues, respectively. The gene expression of MAGEs were also detected in 8/10 (80%) of ovary cancer tissues and in 9/10 (90%) of peritoneal cells of gastric cancer patients in RT-PCR test using S1/AS1 primers. The results of this study suggest that molecular diagnosis method using CTAs genes, especially RT-PCR using S1/AS1 primer combination, is useful for diagnosis of cancer and it will be used for the prediction of cancer progression or regression and metastasis in future.

The most common cause of small bowel obstruction is postoperative adhesion, and besides a hernia, metastatic or primary cancer and small bowel tumors are possible causes. Superior mesenteric artery (SMA) syndrome is a rare cause of upper gastrointestinal obstruction and is associated with debilitating conditions with marked weight loss. SMA syndrome results from the compression of the third part of the duodenum due to the narrowing of the aortomesenteric angle. We report a 28-year-old woman with SMA syndrome after acute gastroenteritis. Her stomach was severely dilated due to the duodenal obstruction and computed tomography showed the compression of the third portion of the duodenum by SMA. She was conservatively cared for and thus favorably improved.

Purpose:
To establish a foundation for raising awareness and disseminating accurate information about enuresis—one of the most challenging conditions to discuss openly—this paper examines public perceptions of enuresis.
Methods:
This paper collected title and text data from posts related to enuresis on the top popular online platforms such Naver Cafe in South Korea and Reddit in the United States (US). The data along with the thematic subcommunities where the posts were uploaded, was analyzed and visualized using word cloud, Latent Dirichlet Allocation (LDA) topic modeling, and pyLDAvis.
Results:
The findings reveal both similarities and differences in how the patients from the 2 countries addressed enuresis online. In both countries, enuresis symptoms were a daily concern, and individuals used online platforms as a space to talk about their experiences. However, South Koreans were more inclined to describe symptoms within region-based communities or mothers’ forums, where they exchanged information and shared experiences before consulting a doctor. In contrast, US patients with medical experience or knowledge frequently discussed treatment processes, lifestyle adjustments, and medication options.
Conclusions
South Koreans tend to be cautious when selecting and visiting hospitals, often relying on others for advice and preparation before seeking medical attention. Compared to online communities in the US, Korean users are more likely to seek preliminary diagnoses based on nonprofessional opinions. Consequently, it is important to lower the barriers for patients to access professional medical advice to mitigate the potential harm of relying on nonprofessional opinions. Additionally, there is a need to raise awareness so that adults can recognize and address their symptoms in a timely manner.

We report here on an uncommon case of peliosis hepatis with hemorrhagic necrosis that was complicated by massive intrahepatic bleeding and rupture, and treated by emergent right lobectomy. We demonstrate the imaging findings, with emphasis on the triphasic, contrast-enhanced multidetector CT findings, as well as reporting the clinical outcome in a case of peliosis hepatis with fatal hemorrhage.

PURPOSE: To investigate the clinical characteristics of retinopathy associated with systemic lupus erythematosus (SLE) and its risk factors. METHODS: Medical records of patients who were diagnosed with SLE were reviewed retrospectively. The presence of retinal hemorrhage, vasculitis and a cotton wool patch were regarded as lupus retinopathy, but concomitant diabetic retinopathy and hypertensive retinopathy were excluded from the study. The correlation between the development of lupus retinopathy and the presence of positive autoantibodies was also investigated. RESULTS: Ocular morbidity was found in 173 of 260 (66%) SLE patients. Retinopathy was detected in 52 eyes of 33 patients (12%), which included 36 eyes of 21 patients (63%) with classic retinopathy and 11 eyes of 10 patients (30%) with vaso-occlusive retinopathy. The presence of classic retinopathy coincided with the flare-up of lupus activity and completely resolved without visual impairment. However, vaso-occlusive retinopathy was not related with lupus activity, and resulted in significant visual impairments of 20/200 or less in six eyes of five patients. The disease activity of lupus assessed by the maximum SLE disease activity index was higher in patients with retinopathy (p<0.05), and the prevalence of antiphospholipid antibody was higher in patients with vaso-occlusive retinopathy than in patients with classic retinopathy (66.7% vs. 37.5%, p<0.05). CONCLUSIONS: Vaso-occlusive retinopathy in SLE can result in permanent visual impairment. Patients with high SLE activity or positive anti-phospholipid antibodies have a high possibility of developing SLE retinopathy and should be referred for ophthalmologic examination.
