OBJECTIVE: To evaluate the effects of cardiac rehabilitation (CR) on functional capacity in obese and non-obese patients who have suffered acute myocardial infarction (AMI). METHODS: Overall, 359 patients who have suffered AMI, and were referred for CR after percutaneous coronary intervention from 2010 to 2015 and underwent an exercise tolerance test before and after phase II CR were included in this study. The patients were divided into two groups: obese group with body mass index (BMI) ≥25 kg/m² (n=170; age, 54.32±9.98 years; BMI, 27.52±2.92 kg/m²) and non-obese group with BMI <25 kg/m² (n=189; age, 59.12±11.50 years; BMI 22.86±2.01 kg/m²). The demographic characteristics and cardiopulmonary exercise capacity of all patients were analyzed before and after CR. RESULTS: There were significant changes in resting heart rate (HR(rest)) before and after CR between the obese and non-obese groups (before CR, p=0.028; after CR, p=0.046), but other cardiopulmonary exercise capacity before and after CR was not different between the groups. HR(rest) (p<0.001), maximal metabolic equivalents (METs, p<0.001), total exercise duration (TED, p<0.001), and maximal oxygen consumption (VO(2max), p<0.001) improved significantly in the obese and non-obese groups after CR. No difference in the change in the cardiopulmonary exercise capacity rate was detected between the groups. CONCLUSION: CR may improve functional capacity in patients who suffered AMI regardless of their obesity.

PURPOSE: Grinding with less stress on 3Y-TZP through proper selection of methods and instruments can lead to a long-term success of prosthesis. The purpose of this study was to compare the phase transformation and physical properties after zirconia surface grinding with 3 different grinding burs. MATERIALS AND METHODS: Forty disc-shaped zirconia specimens were fabricated. Each Ten specimens were ground with AllCeramic SuperMax (NTI, Kahla, Germany), Dura-Green DIA (Shofu Inc., Kyoto, Japan), and Dura-Green (Shofu Inc., Kyoto, Japan). Ten specimens were not ground and used as a control group. After the specimen grinding, XRD analysis, surface roughness test, FE-SEM imaging, and biaxial flexural strength test were performed. RESULTS: After surface grinding, small amount of monoclinic phase in all experimental groups was observed. The phase change was higher in specimens, which were ground with Dura-Green DIA and AllCeramic SuperMax burs. The roughness of surfaces increased in specimens, which were ground with Dura-Green DIA and AllCeramic SuperMax burs than control groups and ground with Dura-Green. All experimental groups showed lower flexural strength than control group, but there was no statistically significant difference between control group and ground with Dura-Green DIA and AllCeramic SuperMax burs. The specimens, which were ground with Dura- Green showed the lowest strength. CONCLUSION: The use of dedicated zirconia-specific grinding burs such as Dura-Green DIA and AllCeramic SuperMax burs decreases the grinding time and did not significantly affect the flexural strength of zirconia, and therefore, they may be recommended. However, a fine polishing process should be accompanied to reduce the surface roughness after grinding.

PURPOSE: This study was conducted to obtain difference in fracture strength according to the diameter of one-body O-ring-type of mini implant fixture, to determine the resistance of mini implant to masticatory pressure, and to examine whether overdenture using O-ring type mini implant is clinically usable to maxillary and mandibular edentulous patients. MATERIALS AND METHODS: For this study, 13 mm long one body O-ring-type mini implants of different diameters (2.0 mm, 2.5 mm and 3.0 mm) (Dentis, Daegu, Korea) were prepared, 5 for each diameter. The sample was placed at 30degrees from the horizontal surface on the universal testing machine, and off-axis loading was applied until permanent deformation occurred and the load was taken as maximum compressive strength. The mean value of the 5 samples was calculated, and the compressive strength of implant fixture was compared according to diameter. In addition, we prepared 3 samples for each diameter, and applied loading equal to 80%, 60% and 40% of the compressive strength until fracture occurred. Then, we measured the cycle number on fracture and analyzed fatigue fracture for each diameter. Additionally, we measured the cycle number on fracture that occurred when a load of 43 N, which is the average masticatory force of complete denture, was applied. The difference on compressive strength between each group was tested statistically using one-way ANOVA test. RESULTS: Compressive strength according to the diameter of mini implant was 101.5 +/- 14.6 N, 149 +/- 6.1 N and 276.0 +/- 13.4 N, respectively, for diameters 2.0 mm, 2.5 mm and 3.0 mm. In the results of fatigue fracture test at 43 N, fracture did not occur until 2x106 cycles at diameter 2.0 mm, and until 5x106 cycles at 2.5 mm and 3.0 mm. CONCLUSION: Compressive strength increased significantly with increasing diameter of mini implant. In the results of fatigue fracture test conducted under the average masticatory force of complete denture, fracture did not occur at any of the three diameters. All of the three diameters are usable for supporting overdenture in maxillary and mandibular edentulous patients, but considering that the highest masticatory force of complete denture is 157 N, caution should be used in case diameter 2.0 mm or 2.5 mm is used.

After recombinant human growth hormone (rhGH) was introduced in the treatment of patients with growth hormone deficiency (GHD) and idiopathic short stature (ISS), many studies have addressed the effect of GH treatment and changes in the height standard deviation score (SDS) after GH treatment. However, few studies comparing the effect of GH in Korean patients with idiopathic GHD and ISS have been designed. Therefore, this study focused on the difference in effect of GH treatment between the two groups. We retrospectively reviewed the height SDS of 34 patients with idiopathic GHD and 12 patients with ISS. The mean ages of the patients with idiopathic GHD and ISS were 9.84+/-2.09 and 10.72+/-1.48 years, respectively. All patients were treated with GH for 1 year and body parameters were recorded before and after the GH treatment. Change in height SDS in patients with idiopathic GHD was significantly higher than that in patients with ISS (0.62+/-0.33 vs. 0.40+/-0.27, p=0.03). However, body mass index, insulin-like growth factor-1, and insulin-like growth factor binding protein-3 were not significantly different between the two groups after GH treatment. These results suggest that GH treatment has a more powerful effect on increasing height SDS in patients with idiopathic GHD than in patients with ISS.

BACKGROUND: Culture based technique, a traditional method for extraction of DNA from a cultured colony, was complex in culture conditions and was associated with a lower chance of successful culture. Recently, non-culture based technique, which skipped the culture process and directly extracted fungal DNA and differentiated Malassezia species, has been introduced. OBJECTIVE: Using 26S rDNA PCR-RFLP, the authors identified Malassezia yeasts and compared the yield of Malassezia DNA by the traditional culture based technique and the non-culture based technique via Op-site adhesive tape. METHODS: DNA of Malassezia yeasts were extracted using the culture based technique and the non-culture based technique from normal adults. Comparison was performed in order to clarify the differences between these two techniques. RESULTS: Use of the culture based technique resulted in a culture rate of 57.8% (78 out of 135 samples). On the other hand, using the non-culture based technique, fungal species were identified from all 135 samples. Using both techniques, M. globosa was the most identified species. The identification rate of the non-culture based technique was 100%; however, 7 repeats of PCR were required to reach 100% identification. Among samples from five body sites, those from the thigh required 5.5 repeats of PCR. CONCLUSION: The non-culture based technique was better than the culture based technique. However, due to the low amount of DNA extracts from the body sites with low habitation of Malassezia yeasts, repeated PCR was required for differentiation of Malassezia species.
