The purpose of this study was to evaluate the spatial changes of mesial-in rotated maxillary molar and opposite anchor tooth during derotation by the precision transpalatal arch (TPA) with the use of a new typodont simulation system, the Calorific machine system, which was designed to observe the whole process of tooth movement. The maxillary right first molar was used for the anchor tooth and the maxillary left first molar was used for the mesial-in rotated tooth, and the angle of rotation was increased to 20, 40, and 60. A passive precision TPA was fabricated and then activated by bending the left arm to 20, 40, and 60. Each experiment was repeated five times under the same conditions and analyzed by ANOVA and Tucky's Studentized Range (HSD) test. In the occlusal plane, when the bending angle of precision TPA was increased, the mesiobuccal cusp of the rotated molar moved more buccally (p<0.001) and less distally (p<0.001) while the distolingual cusp moved in the mesiopalatal direction. In the sagittal plane, the palatal roots of the derotated molar moved mesially (p<0.001). In the traverse plane, the derotated molar showed slight extrusion (p<0.001). The upper right first molar, which was used as an anchor tooth, showed clinically insignificant movement across all three planes.

PURPOSE: Macrovascular complications are the main cause of mortality in type 1 diabetes mellitus (T1DM). The purpose of this study was to clarify the presence of early vascular changes and to assess the risk factors of macrovascular complications in young adults with T1DM diagnosed in childhood and adolescence. METHODS: Seventy-two patients (23.9+/-2.4 years) with T1 DM diagnosed before 18 years of age and twenty normal controls were included. The incidence of hypertension, dyslipidemia, and other risk factors of macrovascular complication were reviewed. Flow-mediated vasodilation (FMD) and mean intima-media thickness (IMT) measured by ultrasound were compared between patients and control subjects, and their correlations with macrovascular risk factors were analyzed. RESULTS: Of the 72 patients, 32 (44.4%) had hypertension. The proportions of maleness (P=0.03) and mean body mass index (P=0.04) were higher in the hypertensive patients than in normotensive patients. Thirty-one (N=69, 44.9%) patients had dyslipidemia and LDL-cholesterol was positively correlated with mean HbA1c (r=0.32, P=0.008) and total daily insulin dose (r=0.27, P=0.02). The mean IMT was significantly higher in patients than in control subjects (0.43+/-0.06 mm vs 0.39+/-0.06 mm, P=0.03). There was no difference in the value of FMD between patients and controls, but the duration of the disease after pubertal onset was negatively correlated with FMD (r=-0.34, P=0.01). CONCLUSION: Hypertension, dyslipidemia and atherosclerotic vascular change were observed in young adults with T1DM diagnosed during childhood and adolescence; this strongly suggests that meticulous screening of macrovascular complications and control of their risk factors should be conducted.

PURPOSE: To investigate the frequency, presentation, management, and outcome of cytomegalovirus (CMV) infection in pediatric patients who underwent renal transplantation. METHODS: We performed a retrospective chart review of 70 patients under the age of 18, who underwent renal transplantation between January 1990 and November 2014. A diagnosis of CMV infection was based on serology, molecular assays, antigenemia assays, and culture. CMV infection was defined as detection of virus and CMV disease was diagnosed when clinical signs and symptoms were present. RESULTS: The number of patients with CMV infection was 18 (25.7% of renal transplant recipients). Twelve were male (66.7%), and the mean±standard deviation (SD) age at infection was 13.3±3.9 years. Median time of infection after renal transplantation was 4 months (range 1.0-31.0 months). Pretransplantation CMV status in the infected group was as follows: donor (D)+/recipient (R)+, 11 (61.1%); D+/R-, 7 (38.9%); D-/R+, 0; and D-/R- 0. Nine patients had CMV disease with fever, leukopenia, thrombocytopenia, or organ involvement such as enteritis, hepatitis, and pneumonitis. The age of disease occurrence was 13.1±3.9 years and the median time to disease onset after renal transplantation was 8 months (range 1.0-31.0). Immunosuppressive agents were reduced or discontinued in 14 patients (77.8%), antiviral agents were used in 11 patients (61.1%), and all patients with CMV infection were controlled. CONCLUSIONS: A quarter of the patients had CMV infection about 4 months after renal transplantation. CMV infection was successfully treated with reduction of immunosuppressants or with antiviral agents.

We examined whether alterations in vascular endothelial function and early structural changes in atherosclerosis are associated with microvascular complications in patients with type 1 diabetes mellitus (DM). Flow-mediated dilation (FMD) of the brachial artery and carotid intima-media thickness (IMT) measurement were performed in 70 young adults (aged 19 to 35 yr), 48 with type 1 DM, and 22 normal controls. Patients with diabetes had a lower peak FMD response (7.8+/-3.9 vs. 11.1 +/-1.9%, p<0.001) and increased IMT (0.51+/-0.10 vs. 0.42+/-0.07 mm, p<0.001) compared with controls. Twenty (41.7%) of the patients had microvascular complications including neuropathy, nephropathy, or retinopathy. In these complicated diabetic patients, we found a lower FMD response (6.1+/-2.5 vs. 9.9+/-3.5%, p=0.001) compared with diabetics without microvascular complications. The presence of microvascular complications was also associated with older age and longer duration of the disease. However, no differences were observed in IMT, body size, blood pressure, HbA1c, C-reactive protein, low-density lipoprotein or high-density lipoprotein cholesterol levels between complicated and non-complicated patients. Endothelial dysfunction and early structural atherosclerotic changes are common manifestations in type 1 DM, and endothelial dysfunction is thought to be an early event in the atherosclerotic process and important in the pathogenesis of microvascular complications.

Subacute sclerosing panencephalitis (SSPE) is a rare, progressive, and fatal central nervous system disorder resulting from persistent measles virus infection. Long-term data are scarce, with a maximum follow-up period of 10 years. Interferon-alpha (IFN-α) is a protein that exerts its antiviral activity via enhancement of cellular immune response and is reported to be an effective drug for the treatment of SSPE. However, there is currently no consensus regarding the optimal duration of IFN-α therapy. Here, we present a case report of a patient with SSPE treated with long-term intraventricular IFN-α therapy, which facilitated clinical improvement and neurological stabilization without causing serious adverse effects. To the best of our knowledge, this is one of the longest follow-up studies investigating a patient with SSPE receiving intraventricular INF-α treatment. Further studies are necessary to validate the benefits and safety of long-term intraventricular IFN-α treatment in patients with SSPE.
