With the development of the digital system in dental field, accurate diagnosis, fixture placement, and convenient prosthetic restoration have become applicable during implant treatment. In this case report, maxillary complete denture and mandibular implant supported fixed prostheses were fabricated in an edentulous patient. Appropriate interim dentures of the maxillary and mandibular were fabricated according to conventional method, and to evaluate the usage of complete denture. In mandibular, multiple implants’ diagnostic analysis upon ideal position was possible using interim denture and the digital system. This case is presented as satisfactory treatment results were achieved after the delivery of definitive prostheses.

Background: This study aimed to compare the mechanical characteristics of four fixation methods including an anatomical suprapectineal quadrilateral surface (QLS) plate in hemipelvic models of anterior column–posterior hemitransverse acetabular fractures typical in elderly patients. Methods: In total, 24 composite hemipelvic models were used and allocated to four groups: group 1, pre-contoured anatomical suprapectineal QLS plate; group 2, suprapectineal reconstruction plate with two periarticular long screws; group 3, suprapectineal reconstruction plate with a buttress reconstruction plate; group 4, suprapectineal reconstruction plate with a buttress T-plate. Axial structural stiffness and displacement of each column fragment in four different fixation constructs were compared. Results: Multiple group comparisons of axial structural stiffness demonstrated significant difference (p = 0.001). Although there was no significant difference between groups 1 and 2 (p = 0.699), group 1 showed greater stiffness than groups 3 and 4 (p = 0.002 and 0.002, respectively). Group 1 showed less displacement in the anterior region of the anterior fragment than group 4 (p = 0.009) and in the posterior region than groups 3 and 4 (p = 0.015 and p = 0.015, respectively). However, group 1 demonstrated greater displacement than group 2 in the posterior region of the posterior fragment (p = 0.004), while showing similar displacement to groups 3 and 4. Conclusions The anatomical suprapectineal QLS plate provided the mechanical stability comparable or superior to other existing fixations in osteoporotic models of anterior column–posterior hemitransverse acetabular fractures typical in the elderly. However, additional plate modification would be needed for better stability and outcomes.

Background/Aims: We performed a prospective study to determine the efficacy and safety of rituximab including chemotherapy in CD20-positive acute lymphoblastic leukemia (ALL). Methods: Patients with newly diagnosed ALL, aged ≥ 15 years, were eligible for the study if their leukemic blast cells in bone marrow expressed CD20 ≥ 20% at the time of diagnosis. Patients received multiagent chemotherapy with rituximab. After achieving complete remission (CR), patients received five cycles of consolidation with concomitant rituximab. Rituximab was administered monthly from day 90 of transplantation for patients who received allogeneic hematopoietic cell transplantation. Results: In patients with Philadelphia (Ph)-negative ALL, 39 of 41 achieved CR (95.1%), the 2- and 4-year relapse-free survival (RFS) rates were 50.4% and 35.7%, and the 2- and 4-year overall survival (OS) rates were 51.5% and 43.2%, respectively. In the group with Ph-positive ALL, all 32 patients achieved CR, the 2- and 4-year RFS rates were 60.7% and 52.1%, and the 2- and 4-year OS rates were 73.3% and 52.3%, respectively. In the Ph-negative ALL group, patients with higher CD20 positivity experienced more favorable RFS (p < 0.001) and OS (p = 0.06) than those with lower CD20 positivity. Patients who received ≥ 2 cycles of rituximab after transplantation had significantly improved RFS (hazard ratio [HR], 0.31; p = 0.049) and OS (HR, 0.29; p = 0.021) compared with those who received < 2 cycles. Conclusions The addition of rituximab to conventional chemotherapy for CD20-positive ALL is effective and tolerable (Clinicaltrials. gov NCT01429610).

We performed a point seroprevalence survey of measles among healthcare workers (HCWs) at two Korean teaching hospitals in 2019. A total of 2,830 HCWs underwent an antibody test.The overall seropositivity of measles was 93.1%. The seroprevalence of measles was lowest in HCWs aged 20 - 24 years (81.2%), followed by those aged 25 - 29 years (90.1%). The rates of anti-measles IgG positivity were significantly different between the two hospitals (97.0% vs.89.4%, P <0.001). These results suggest that the seropositivity of measles in HCWs may differ depending on the hospital's vaccination policy.

BACKGROUND: Chronic cough is defined as a cough lasting more than 8 weeks and socio-economic burden of chronic cough is enormous. The characteristics of chronic cough in Korea are not well understood. The Korean Academy of Tuberculosis and Respiratory Diseases (KATRD) published guidelines on cough management in 2014. The current study evaluated the clinical characteristics of chronic cough in Korea and the efficacy of the KATRD guidelines. METHODS: This was a multi-center, retrospective observational study conducted in Korea. The participants were over 18 years of age. They had coughs lasting more than 8 weeks. Subjects with current pulmonary diseases, smokers, ex-smokers with more than 10 pack-years or who quit within the past 1 year, pregnant women, and users of cough-inducing medications were excluded. Evaluation and management of cough followed the KATRD cough-management guidelines. RESULTS: Participants with chronic cough in Korea showed age in the late forties and cough duration of more than 1 year. Upper airway cough syndrome was the most common cause of cough, followed by cough-variant asthma (CVA). Gastro-esophageal reflux diseases and eosinophilic bronchitis were less frequently observed. Following the KATRD cough-management guidelines, 91.2% of the subjects improved after 4 weeks of treatment. Responders were younger, had a longer duration of cough, and an initial impression of CVA. In univariate and multivariate analyses, an initial impression of CVA was the only factor related to better treatment response. CONCLUSION The causes of chronic cough in Korea differed from those reported in other countries. The current Korean guidelines proved efficient for treating Korean patients with chronic cough.
