심하게 흡수된 치조제를 지닌 환자에게 적절한 의치를 제공하기 위한 한 가지 방법으로써 중립대 인상 기법을 이용한 의치의 제작을 고려해 볼 수 있다. 중립대 내에 인공 치아를 배열하는 것은 다음의 두 가지 목적을 이루고자 함이다. 첫째, 치아가 정상적인 근육의 기능을 방해하지 않도록 하기 위함이며, 둘째, 의치에 저항하여 가해지는 근육 조직의 힘이 안정과 유지에 더 유리하게 작용할 수 있도록 하기 위함이다. 본 증례의 환자는 심한 잔존 치조제의 흡수를 보이는 78세 여자 환자로 오랜 기간 불안정한 상 하악 총의치를 사용하고 있었다. 의치의 안정과 유지를 향상시키기 위하여 중립대 인상 기법을 통한 새로운 의치의 제작을 계획하였다. Modeling compound를 이용하여 중립대를 인기하였으며 치아 배열 후 external impression을 시행함으로써 정확한 연마면을 형성할 수 있었다. 완성된 상 하악 총의치는 보다 향상된 안정과 유지를 보였으며 환자 역시 새로 제작된 의치에 만족감을 보였기에 이를 보고하고자 한다.

Purpose: The aim of this retrospective study was to compare marginal bone loss and survival rates of double short implants(multiple implant) which had been installed and restored in severely atrophic maxillary molar site without a grafting procedure. Material and Method: The subjects were patients (90 patients, 180 implants) who had been installed double short implants in severely atrophic maxillary single molar site without bone augmentation procedure from 2006 to 2014 in dental clinic in Chuncheon city. Following data were collected from dental records and radiographic panoramic views: patient's age, gender, smoking status, implant site, timing of implant installation, residual ridge height. The correlation between those factors and survival rate and marginal bone loss were analyzed. Statistical analysis was performed using Chi-square test, Student's t- test and ANOVA. Result: Eleven implants in 6 patients failed and the cumulative survival rate was 93.9%. No significant differences were found in relation to the following factors: patient's age, gender, implant site, timing of implant installation (P> .05). There were significant differences in smoking status and residual ridge height(P< .05). The average follow-up time was $45{\pm}14.7months$. The mean marginal bone loss of survived 169 implants was $0.08{\pm}0.59mm$. Conclusion: Despite the short term outcomes, the survival rate of double short implants was comparable to normal length implants. This study demonstrated that placement of double short implants without the use of bone grafting procedure for severely atrophic posterior maxilla is a simple and predictable treatment procedure.

Two dogs (Case 1: Poodle, 4 years old, spayed female; Case 2: Bulldog, 3 years old, intact female) were referred to us for treatment of vomiting; Case 1 had a history of acute vomiting that started 1 day prior to presentation, and Case 2 had a history of chronic vomiting that started 2 years prior to presentation. The vomiting did not respond to medication in the local animal hospital. Results from abdominal ultrasound examinations showed that case 1 had gastric wall thickening, and case 2 had no remarkable findings. For both cases, we performed gastrointestinal endoscopic examinations, and several biopsy samples were obtained from different gastric areas. On the basis of the results of histopathological examinations, both dogs were diagnosed with atrophic gastritis concurrent with a Helicobacter infection. Clinical signs improved after antibiotic therapy. This case report describes the clinical, endoscopic, and histopathological findings of atrophic gastritis concurrent with a Helicobacter infection.

Background/Aims: The etiology of superficial non-ampullary duodenal epithelial tumors (SNADETs) remains unclear. Recent studies have reported conflicting associations between duodenal tumor development and Helicobacter pylori infection or endoscopic gastric mucosal atrophy. As such, the present study aimed to clarify the relationship between SNADETs and H. pylori infection and/or endoscopic gastric mucosal atrophy. Methods: This retrospective case-control study reviewed data from 177 consecutive patients with SNADETs who underwent endoscopic or surgical resection at seven institutions in Japan over a three-year period. The prevalence of endoscopic gastric mucosal atrophy and the status of H. pylori infection were compared in 531 sex- and age-matched controls selected from screening endoscopies at two of the seven participating institutions. Results: For H. pylori infection, 85 of 177 (48.0%) patients exhibited SNADETs and 112 of 531 (21.1%) control patients were non-infected (p<0.001). Non-atrophic mucosa (C0 to C1) was observed in 96 of 177 (54.2%) patients with SNADETs and 112 of 531 (21.1%) control patients (p<0.001). Conditional logistic regression analysis revealed that non-atrophic gastric mucosa was an independent risk factor for SNADETs (odds ratio, 5.10; 95% confidence interval, 2.44-8.40; p<0.001). Conclusions: Non-atrophic gastric mucosa, regardless of H. pylori infection status, was a factor independently associated with SNADETs.

The advent of osseointegration and advances in biomaterials and techniques have contributed to increased application of dental implants in the restoration of maxillary partial edentulous patients. Often, in these patients, soft and hard tissue defects result from a variety of causes, such as infection, trauma, and tooth loss. These create an anatomically less favorable foundation for ideal implant placement. Reconstruction of the atrophic maxillary alveolar bone through a variety of regenerative surgical procedures has become predictable; it may be necessary prior to implant placement or simultaneously at the time of implant surgery to provide a restoration with a good long-term prognosis. Regenerative procedures are used for horizontal and vertical ridge augmentation. Many different techniques exist for effective bone augmentation. The approach is largely dependent on the extent of the defect and specific procedures to be performed for the implant reconstruction. It is most appropriate to use an evidenced-based approach when a treatment plan is being developed for bone augmentation cases. The cases presented in this article clinically demonstrate the efficacy of using a autogenous block graft, guided bone regeneration, ridge split, immediated implant placement technique on the atrophic maxillary area.

Objectives: To evaluate the effectiveness and safety of application of Traditional East Asian Herbal Medicine (TEAM) in the treatment of Atrophic Vaginitis (AV). Methods: Randomized Controlled Trials (RCTs) were obtained from PubMed, Cochrane Library, Embase, CNKI, RISS, NDSL, and KISS. The risk of bias was assessed by using Cochrane's risk of bias tool, and RevMan 5.3 software was used. Results: 26 RCTs with 3,162 patients were identified and reviewed. Among them, 21 RCTs observe the effect of integrated traditional Chinese and Western medicine. 23 RCTs reported treatment groups was statistically effective than control groups in the study. Also, the recurrence rate was estimated in 10 RCTs and was lower than control groups. 12 studies observed adverse events (AEs) and severe AEs were not reported. Conclusions: This review suggested that TEAM was safe and effective in the treatment of AV. TEAM may also decrease the recurrence rate. However, this could not be proven conclusively. To ensure evidence-based clinical practice, well-designed trials with larger sample sizes are needed.

Bordetella bronchiseptica and Pasteurella multocida are two main pathogens responsible for atrophic rhinitis (AR), which causes considerable economic losses in swine industry worldwide. Commercial vaccine has been widely used to prevent the damage from AR in Korea. Adverse effects of vaccination at the injection site have been reported, which results in the numerous complaint from farms. However, data on about local reaction at the injection site remains limited. In this study, we compared the local adverse effects of three commercial vaccines following intramuscular injection. The results showed that no gross lesion was founded at the injection sites of all three vaccines. In histopathologic examination, a various level of lesions was identified. Especially, the local reaction of vaccine including saponin as an adjuvant showed the lowest level of histopathological lesions, when compared to those of oil-based and vitamin E-based vaccines. Therefore, this study would provide the information about the extent of local reaction at the injection site and help the farmer to select AR vaccine in order to avoid adverse reaction due to vaccination.
