PURPOSE: The aim of this study was to evaluate whether there is any typical deformation pattern existing in complete denture when it was dried by using the 3D scanner and surface matching program. MATERIALS AND METHODS: A total of 28 denture bases were fabricated with heat curing acrylic resin (each 14 upper and lower denture bases), and 14 denture bases (each 7 upper and lower denture bases) were stored in the water bottle (water stored), and another 14 denture bases were stored in the air (dry stored). Each specimen was scanned at 1st day after deflasking, 14th day after deflasking, and 28th day after deflasking, and digitalized. Three dimensional deformation patterns were acquired by comparison of the data within storage group using surface matching program. For evaluating differences between groups, these data were compared statisticallyusing Kruskal Wallis and Mann Whitney-U test (α=.05). RESULTS: When evaluating 3D deformation of denture base, obvious deformations were not found in maxillary and mandibular water storage group. However, in dry stored group, typical deformation pattern was detected as storage time passes. It occurred mostly in first two weeks. Major deformations were found in the bilateral posterior area in both maxillary and mandibular group. In maxillary dry stored group, a statistical significance was found. CONCLUSION: It was proved that in both upper and lower denture bases, dry storage caused more dimensional deformation than water storage with typical pattern.

Suction dentures enhance retention and support by forming negative pressure temporarily at the internal surface of denture base at times of swallowing and chewing because the areas surrounding the denture flanges are sealed by mobile mucosa. In this case, an 81-year-old male visited for new dentures. Considering the high expectations for retention and masticatory efficiency of dentures, fabricating complete dentures with suction dentures was planned. Preliminary impression was taken without applying pressure on retromolar pad area and diagnostic cast was fabricated. Afterwards, individual tray was made and final impression was taken, at the same time, gothic arch tracing was done to acquire centric relation and vertical dimension. Then, anatomic teeth were placed on maxilla and non-anatomic teeth were placed on mandible forming lingualized occlusion. Consequently, restoring a complete edentulous patient with complete dentures using mandibular suction denture resulted in recovering satisfying retention and function.

All-trans retinoic acid (ATRA) is a potent differentiating agent for the treatment of acute promyelocytic leukemia (APL). Although ATRA is generally well-tolerated, some patients develop side effects, the most severe of which is ATRA syndrome. We report on a patient with APL who developed isolated nephrotic-range proteinuria during ATRA therapy for remission-induction. ATRA was discontinued and the proteinuria decreased significantly 5 days after dexamethasone treatment. The occurrence of isolated proteinuria during ATRA treatment is a rare adverse event.

PURPOSE: To investigate the differences in clinical features and laboratory findings between group D and non-group D non-typhoidal Salmonella (NTS) gastroenteritis in children. METHODS: A retrospective chart review of children diagnosed with NTS confirmed by culture study was performed. The clinical features and laboratory findings of group D and non-group D NTS were compared. RESULTS: From 2003 to 2012, 75 cases were diagnosed as NTS at our center. The number of group D and non-group D patients was 45 and 30, respectively. The mean age was higher in group D than in non-group D patients (5.1 years vs. 3.4 years, p=0.038). Headaches were more frequently observed (p=0.046) and hematochezia was less frequently observed (p=0.017) in group D than in non-group D NTS gastroenteritis patients. A positive Widal test result was observed in 53.3% of group D and 6.7% of non-group D NTS cases (O-titer, p=0.030; H-titer, p=0.039). There were no differences in white blood cell counts, level of C-reactive protein and rate of antimicrobial resistance between group D and non-group D cases. CONCLUSION: The more severe clinical features such as headache, fever, and higher Widal titers were found to be indicative of group D NTS gastroenteritis. Additionally, group D NTS gastroenteritis was more commonly found in older patients. Therefore, old age, fever, headache, and a positive Widal test are more indicative of group D NTS than non-group D NTS gastroenteritis. Pathophysiological mechanisms may differ across serologic groups.
