Full mouth rehabilitation in patient with deep bite, inter-dental arch discrepancy and loss of vertical dimension: a case report

Loss of posterior bite support might cause unstable occlusal relationship and when the mandible slides forward in the centric or habitual occlusion, excessive load is applied to the anterior region followed by causing the occlusal plane to collapse or leading to a decrease in occlusal vertical dimension. In addition, disorder of temporomandibular joint function may occur. The inter-dental arch discrepancy causes a mismatch in the vertical and horizontal overlap of the anterior and posterior regions. The deep bite in the anterior region and the scissor bite in the posterior region cause unstable occlusal contact and insufficient occlusal contact area. This report was to rehabilitate a patient with above-mentioned complex problems. Physiologic adaptation to increased vertical dimension and new occlusal plane were evaluated using provisional prostheses, and definitive prostheses was fabricated using cross-mounting technique. Stable occlusion, harmonious teeth overlap and adequate occlusal plane were established, so functionally and aesthetically satisfactory results are obtained.

Comparison of changes in the transverse dental axis between patients with skeletal Class III malocclusion and facial asymmetry treated by orthognathic surgery with and without presurgical orthodontic treatment / 대한치과교정학회지

OBJECTIVE: To evaluate transverse skeletal and dental changes, including those in the buccolingual dental axis, between patients with skeletal Class III malocclusion and facial asymmetry after bilateral intraoral vertical ramus osteotomy with and without presurgical orthodontic treatment. METHODS: This retrospective study included 29 patients with skeletal Class III malocclusion and facial asymmetry including menton deviation > 4 mm from the midsagittal plane. To evaluate changes in transverse skeletal and dental variables (i.e., buccolingual inclination of the upper and lower canines and first molars), the data for 16 patients who underwent conventional orthognathic surgery (CS) were compared with those for 13 patients who underwent preorthodontic orthognathic surgery (POGS), using three-dimensional computed tomography at initial examination, 1 month before surgery, and at 7 days and 1 year after surgery. RESULTS: The 1-year postsurgical examination revealed no significant changes in the postoperative transverse dental axis in the CS group. In the POGS group, the upper first molar inclined lingually on both sides (deviated side, −1.8°± 2.8°, p = 0.044; nondeviated side, −3.7°± 3.3°, p = 0.001) and the lower canine inclined lingually on the nondeviated side (4.0°± 5.4°, p = 0.022) during postsurgical orthodontic treatment. There were no significant differences in the skeletal and dental variables between the two groups at 1 year after surgery. CONCLUSIONS: POGS may be a clinically acceptable alternative to CS as a treatment to achieve stable transverse axes of the dentition in both arches in patients with skeletal Class III malocclusion and facial asymmetry.

Effect of Music Intervention on Maternal Anxiety and Fetal Heart Rate Pattern During Non-Stress Test

PURPOSE: The purpose of this cross-over experimental study was to examine effects of music intervention on maternal anxiety, fetal heart rate pattern and testing time during non-stress tests (NST) for antenatal fetal assessment. METHODS: Sixty pregnant women within 28 to 40 gestational weeks were randomly assigned to either the experimental group (n=30) or control group (n=30). Music intervention was provided to pregnant women in the experimental group during NST. Degree of maternal anxiety and fetal heart rate pattern were our primary outcomes. State-trait anxiety inventory, blood pressure, pulse rate, and changes in peripheral skin temperature were assessed to determine the degree of maternal anxiety. Baseline fetal heart rate, frequency of acceleration in fetal heart rate, fetal movement test and testing time for reactive NST were assessed to measure the fetal heart rate pattern. RESULTS: The experimental group showed significantly lower scores in state anxiety than the control group. There were no significant differences in systolic blood pressure and pulse rate between the two groups. Baseline fetal heart rate was significantly lower in the experimental group than in the control group. Frequency of acceleration in fetal heart rate was significantly increased in the experimental group compared to the control group. There were no significant differences in fetal movement and testing time for reactive NST between the two groups. CONCLUSION: Present results suggest that music intervention could be an effective nursing intervention for alel viating anxiety during non-stress test.

Drug reaction with eosinophilia and systemic symptom induced in a 9-year-old boy

The drug reaction with eosinophilia and systemic symptom (DRESS) is a severe adverse drug-induced reaction. Acetaminophen is extensively used as an over-the-counter drug as well as a medical therapeutic. In spite of its frequent use, drug eruptions related to DRESS caused by acetaminophen are rare. This case report describes a 9-year-old boy who experienced fever and maculopapular skin rashes after taking acetaminophen. Leukocytosis with marked eosinophilia and slightly elevated levels of liver enzymes were observed. Symptoms resolved after withdrawal of acetaminophen, followed by intravenous methylprednisolone administration. The diagnosis of DRESS induced by acetaminophen was confirmed by an oral challenge test after 2 months. No allergic reactions to ibuprofen were observed.

The Effect of Circuit Training and Workplace Improvement Program on the Prevention of Metabolic Syndrome and the Improvement of Physical Function in Office Workers

BACKGROUND: Physical inactivity and reduced energy expenditure lead to increase in obesity among office workers. In this study, we investigated how 10 weeks of high intensity circuit training and working environment improvement can change body composition, physical strength and markers of metabolic syndrome. METHODS: A total of 83 employees at risk for metabolic syndrome participated in 10 weeks program of one-hour circuit training (30 minutes twice weekly) and workplace improvement program, which consisted of dynamic stretching twice daily for all weekdays. Body composition, anthropometry, blood test, muscle strength/endurance and cardiopulmonary function of participants were assessed at the baseline and after 10 weeks. RESULTS: At the end of 10 weeks, significant increases in levels of body composition, serum lipids, muscle strength and cardiopulmonary were observed in metabolic syndrome risk factor group. In body composition, significant improvements of body weight, body mass index, lean body mass, %body fat, visceral adipose tissue, waist and hip circumference and systolic blood pressure, diastolic blood pressure were observed in metabolic syndrome risk factor group. In lipids, hemoglobin A1c and high density lipoprotein were increased significantly in metabolic syndrome risk factor group. In muscle strength and endurance, significant increases were found. Also, there was a significant difference in cardiovascular function of maximal oxygen uptake and total running time among the groups. CONCLUSIONS: These intensive 10 weeks of high intensity circuit training and workplace improvement program were effective in improving body composition, muscle strength/improvement and cardiopulmonary function. Therefore, based on this study result, workplace improvement programs might be more developed and applied for high-risk employees to improve their metabolic syndrome.

Effects of High-speed Elastic Band Training on Physical Fitness and Muscle Function in Rural Community-dwelling Elderly: a Single-blinded Randomized Controlled Trial

BACKGROUND: Aging related decrease in muscle strength and flexibility leads to functional loss of physical ability. Power training is known to improve these capacities and helps in performing daily routine better. Therefore, we modified previously proven and certified sarcopenia intervention exercise for elderly in rural community and applied them to examine the effects on physical fitness and muscle functions to show its applicability. METHODS: Subjects were divided into control and exercise group using single-blind method. Exercise group underwent high-speed elastic band training(concentric contraction in 1 second) 2 days per week for 12 weeks. Before and after the intervention, we performed body composition analysis, anthropometric measurement, blood test, blood pressure check, senior fitness test (SFT), upper body and lower body strength examination. Korean version of Physical Activity Scale for the Elderly (K-PASE), and Center for Epidemiological Studies- Depression Scale (CES-D) were also assessed. RESULTS: Body weight in control group was significantly increased (Paired t-test: P=0.008), although it was consistent in exercise group (GroupxTime: P=0.013). 30-second chair stand (P<0.001) and 30-second arm curl (P<0.001) of the senior fitness test were also significantly improved in exercise group compared to control. In addition, muscle strength of knee flexion (P=0.034) and K-PASE score (P<0.001) were improved in training group with statistical significance. CONCLUSIONS: The modified high-speed elastic band training for rural elderly improved muscle strength and daily physical performance. This result suggests a simple and easy to perform band training could be an excellent solution to prevent sarcopenia in rural elderly. It also supports the evidence that this program would be widely distributed.

Practical Application of Resistance Exercise for Prevention of Sarcopenia

Sarcopenia is a major component of age-related frailty and also a strong predictor of disability, morbidity, and mortality in the aging population. Resistance exercise could be the most effective intervention that improves muscle mass, muscle strength, and physical performance, thus preventing sarcopenia in older adults. The benefits of these exercise programs correlate with the intensity and the frequency of the exercise regimes used in the trials. Clinical trials vary in terms of population, setting, and exercise regimes; hence, more standardized clinical trials are required. In this review, we focus on the effects of resistance exercise on muscle mass, strength, cognitive and physical function, and the principle and applications of resistance exercise considering recent trends that include high-intensity interval training, high speed power training, eccentric exercise, and whole-body vibration exercise.

Relationship between serum insulin-like growth factor-1, IGF binding protein-3 levels and body height before and after gonadotropin-releasing hormone agonist therapy

PURPOSE: The gonadotropin-releasing hormone agonist (GnRHa) is widely used to treat patients with precocious puberty. However, its effect on growth is often difficult to predict because of the diverse nature of its causes and presentation. This study aims to show the impact of GnRHa treatment on insulin-like growth factor-1 (IGF-I) and IGF binding protein-3 (IGFBP-3) secretion, growth, and on other parameters that may help estimate the height velocity. METHODS: Data from 60 girls (mean age, 8.8+/-0.7 years) treated with GnRHa were analyzed. Their height, bone age (BA), serum IGF-I, and IGFBP-3 concentrations were measured at the start and after a year of GnRHa treatment. To eliminate the confounding effect of chronological age (CA), the standard deviation scores (SDSs) of their height, IGF-I, and IGFBP-3 concentrations according to their CA at the start and after a year of GnRHa treatment were calculated. We looked for possible correlations between these variables and compared the subgroups based on their height velocities and midparental heights. RESULTS: During their one-year GnRHa therapy, height SDS for CA significantly decreased to 0.81+/-0.83 (P<0.001), but height SDS for BA increased to -0.28+/-0.68 (P<0.001). There was no significant change in serum IGF-I SDS, IGFBP-3 SDS, and IGF-I/IGFBP-3 ratio. The advanced BA was the factor most strongly correlated to the height velocity (R=0.265, P=0.041). CONCLUSION: These findings suggest that GnRHa treatment may affect the height velocity due to mechanisms other than suppression of the IGF-I and IGFBP-3 secretory axis.
