Rice-based breakfast improves fasting glucose and HOMA-IR in Korean adolescents who skip breakfast, but breakfast skipping increases aromatic amino acids associated with diabetes prediction in Korean adolescents who skip breakfast: a randomized, parallel-group, controlled trial

BACKGROUND/OBJECTIVES@#Adolescents who skip breakfast have an increased prevalence of chronic diseases. Thus, we aimed to evaluate whether the intake of rice-based breakfast had positive effects on blood glucose indices and to determine the possibility of diabetes prevalence in Korean youths who habitually skip breakfast. @*SUBJECTS/METHODS@#In this randomized parallel-group controlled trial, 81 subjects who were suitable for compliance among 105 middle-and high-school students aged 12-18 years who usually skipped breakfast were included in this study (rice-meal group [RMG], n = 26; wheat-meal group [WMG], n = 29; general-meal group [GMG], n = 26). The RMG and WMG received a rice-based breakfast and a wheat-based breakfast for 12 weeks, respectively. The anthropometric indices, blood glucose indices, and metabolites were measured at baseline and the endpoint, respectively. @*RESULTS@#The mean body weights in the RMG, WMG, and GMG groups at the endpoint were 62.44 kg, 61.80 kg, and 60.28 kg, respectively, and the mean body weights of the WMG and GMG groups at the endpoint were significantly higher than that at baseline (P < 0.05). The levels of fasting insulin and homeostasis model assessment of insulin resistance (HOMA-IR) values were significantly decreased in the RMG group at the endpoint compared to baseline (P < 0.05, P < 0.05, respectively). The levels of tryptophan and tyrosine in the WMG group at the endpoint were significantly higher than that those at baseline (P < 0.01, P < 0.05, respectively). @*CONCLUSIONS@#Rice-based breakfast has positive effects on fasting insulin levels and HOMA-IR in Korean adolescents who skip breakfast. Additionally, it was found that a skipping breakfast could increase the prevalence of diabetes in adolescents who skip breakfast. Therefore, in addition to reducing breakfast skipping, it is vital to develop a ricebased menu that fits teenage preferences to prevent chronic diseases such as diabetes.

The Prevalence of Rapid Eye Movement Sleep Behavior Disorder in Amyloid Positron Emission Tomography Positive Alzheimer's Disease

OBJECTIVES@#Rapid eye movement (REM) sleep behavior disorder (RBD) is well known as a prodromal symptom of neurodegenerative disease, especially α-synucleinopathy. In the previous literature, it has been reported the incidence rate of RBD in Alzheimer's disease (AD) is about 10%. This incidence rate is relatively low, if we consider that nearly half of AD patients also have Lewy body pathology. The objective of this study is to determine the incidence rate of RBD among patients with AD, confirmed by amyloid positron emission tomography (PET) image.@*METHODS@#We enrolled 57 patients with clinically probable AD patients who identified AD pathology in amyloid PET scan. RBD was evaluated with REM sleep behavior disorder questionnaire-Korean vesion (RBDQ-KR), which validated the RBD screening questionnaire as Korean version to confirm RBD. Detailed neuropsychological tests were measured using the Seoul Neuropsychological Screening Battery (SNSB).@*RESULTS@#We analyzed RBDQ-KR data collected from 57 AD patients. Dementia due to AD was 36 patients (63.2%) and mild cognitive impairment (MCI) due to AD was 21 (36.8%). AD with RBD was 14 (24.6%). Among these, AD dementia with RBD was 13 (36.1%), and MCI due to AD with RBD was 1 (4.8%). There were no significant differences in cognitive function between the patients with or without RBD, evaluated by detailed neuropsychological test.@*CONCLUSIONS@#In this study, the incidence of RBD in AD was not rare; therefore, if the patient shows symptoms of RBD, we should not rule out AD.

Evaluation of dietary habits according to breakfast consumption in Korean adolescents: based on the 6(th) Korea National Health and Nutrition Examination Survey, 2013 ~ 2015 / 한국영양학회지

PURPOSE: This study examined the nutrient intake and dietary habits based on breakfast consumption in Korean adolescents. METHODS: The data of the 2013 ~ 2015 Korea National Health and Nutrition Examination Survey (KNHANES) were used in this study. The analysis included 1,281 adolescents aged 12 to 18 years. The subjects were divided into two groups (EBF: eating breakfast, n = 911; SBF: skipping breakfast, n = 370). RESULTS: The EBF group was significantly younger than the SBF group. In addition, the EBF group had a significantly lower frequency of skipping dinner than the SBF group. The EBF group consumed significantly higher levels of most nutrients except for vitamin A than the SBF group. The percent of nutrient intake under the EAR (estimated average requirements) in the EBF group were also significantly lower than that in the SBF group. Moreover, the NAR (nutrient adequacy ratio) and MAR (mean adequacy ratio) of the EBF group were significantly higher than those of the SBP group. The intake of cereal, sugars and sweeteners, vegetables, and eggs in the EBF group was significantly higher than that in the SBF group. CONCLUSION: The habit of skipping breakfast in adolescents leads to a decrease in the total nutrient intake and imbalanced dietary habits. Breakfast consumption in adolescence is very important. Therefore, more studies will be needed to develop nutrition education systematically in Korean adolescents.

A retrospective clinical study of single short implants (less than 8 mm) in posterior edentulous areas

PURPOSE: The goal of this study was to evaluate the clinical outcome of single short implants, less than 8 mm in length, placed in the posterior area. MATERIALS AND METHODS: A total of 128 patients (75 male and 53 female, mean age: 52.6±11.2 years) with 154 implants participated. Implant marginal bone loss, and survival and success rates were measured. RESULTS: The mean follow-up period was 51.35±24.97 months. A total of 128 implants, 8 mm in length, were placed in patients who had mean marginal bone loss of 0.75 mm. These implants had a survival rate of 95.3%. Twenty-six implants, 7 mm in length, were placed in areas with a mean marginal bone loss of 0.78 mm and had a survival rate of 96.2%. Both marginal bone loss and survival rate were not statistically different among the groups. In the maxilla, 34 implants showed a mean marginal bone loss of 0.77 mm and a survival rate of 97.1%. In the mandible, 120 implants showed a mean marginal bone loss of 0.75 mm and a survival rate of 95.0%. The average marginal bone loss around all implants was 0.76±0.27 mm at the last follow-up review after functional loading. The survival rate was 95.6% and success rate was 93.5%. CONCLUSION: In our study, single short implants less than 8 mm in length in the posterior areas had favorable clinical outcomes.

Extraction socket sealing using palatal gingival grafts and resorbable collagen membranes / 대한악안면성형재건외과학회지

BACKGROUND: Socket sealing surgery is performed for the preservation of the form and volume of the soft tissue by covering the resulting socket with autogenous soft tissue graft or membrane barriers. This procedure is usually necessary to improve the esthetic results of the maxillary anterior or premolar areas. METHODS: This study retrospectively investigated cases involving the open membrane technique or socket sealing surgery with a palatal gingival graft or collagen membrane where implant placement and bone grafting were performed immediately after tooth extraction. From January 2005 to December 2008, socket sealing surgery was performed in 24 patients, and 25 implants were placed. RESULTS: All implants were successful in the follow-up period. In the palatal gingival graft group, the mean marginal bone loss was 1.17 mm during the mean follow-up period of 81.0 months. In the collagen membrane group, the mean marginal bone loss was 1.23 mm during the mean follow-up period of 76.9 months. There was no significant difference between the two groups. CONCLUSIONS: Consequently, socket sealing surgery is effective at minimizing the loss of soft tissue and alveolar bone.

Evaluation of bone healing using rhBMP-2 soaked hydroxyapatite in ridge augmentation: a prospective observational study / 대한악안면성형재건외과학회지

BACKGROUND: The goal of this study is to evaluate complication and effectiveness of alveolar ridge augmentations using a hydroxyapatite-based alloplastic bony substitute with rhBMP-2. METHODS: A total of 10 patients (4 males, 6 females; 58.5 ± 8.6 years) participated in this clinical research. Alveolar ridge augmentations were performed in edentulous (4 maxillary posterior, 5 mandibular posterior, and 1 mandibular anterior) regions. Anorganic bovine bone (ABB; Bio-Oss®, Geistlich Pharma AG, Wolhusen, Switzerland) was used as the bone graft material in the control group (n = 5)) while hydroxyapatite-based alloplastic bony substitute with rhBMP-2(HA+rhBMP-2; NOVOSIS®-Dent, CGBio Inc., Seongnam, Korea) was used in the experimental group (n = 5). In order to evaluate relative changes in bone volume and resorption rate of the bone graft material, CBCT radiographs were taken immediately and at 4 months after the bone graft in all subjects. Among the 10 patients, 8 received dental implants in Seoul National University Bundang Hospital, while the others received in local clinics. Bone specimens for further histomorphometric examinations were gained from these 8 patients using trephine burs during the implant placements. Clinical, radiographic, and histomorphometric evaluations were focused because of the small sample size. RESULTS: When CBCT radiographs were compared between immediately and at 4.07 ± 0.13 months after the bone graft, both alveolar bone widths (ABB 2.52 ± 0.18 mm, HA+rhBMP-2 1.75 ± 0.85 mm) and heights (ABB 1.68 ± 0.17 mm, HA+rhBMP-2 1.57 ± 0.28 mm) increased in the two groups. Resorption rates of transplanted bone graft material in the alveolar bone widths and heights were (ABB 29.7 ± 8.8%, HA+rhBMP-2 31.5 ± 7.4%) and (ABB 39.2 ± 21.8%, HA+rhBMP-2 52.6 ± 6.5%), respectively. Histomorphometrically, ABB group showed bone formation via osteoconduction and HA+rhBMP-2 group via osteoinduction. HA+rhBMP-2 group showed more bone formation around the bone graft materials than the ABB group. Postoperative complications were not found in all subjects. CONCLUSIONS: Our study had following conclusions: (1) Ridge augmentations using HA+rhBMP-2 could be clinically useful to supplement implant placements in edentulous regions. (2) Serious postoperative complications related to the graft material did not occur.

Intentional partial odontectomy—a long-term follow-up study / 대한악안면성형재건외과학회지

BACKGROUND: The surgical extraction of the third molar is the most frequently encountered procedure in oral and maxillofacial surgery and is related with a variety of complications. This study examined the efficacy of intentional partial odontectomy (IPO) in the third molars which have no periapical lesions and are located near important anatomical structures such as inferior alveolar nerve. METHODS: Seven patients (four males, three females, 39.1 ± 11.6 years), who received IPO to reduce the risk of inferior alveolar nerve injury (IANI), were followed long-term. The treated teeth were horizontally impacted third molars in the mandibular left (n = 5) or mandibular right (n = 4) areas and were all ankylosed with the surrounding alveolar bone. During the IPO, the bone around the crown was removed to expose the crown, and then the tooth was resected at cement-enamel junction (CEJ). Any secondary trauma to the healthy root was minimized and remained intact after primary suture. RESULTS: The mean follow-up time was 63.2 ± 29.8 months, and all sites showed good bone healing after the crown removal. Also, sensory abnormality was not found in any patients after IPO. In one patient, the bone fragments erupted 4 months after IPO. In other patient, an implant placed on second molar site adjacent to the third molar that received IPO was explanted about 2 years after the patient’s persistent discomfort. CONCLUSIONS: In case where high risk of IANI exists, IPO may be chosen alternatively to surgical extraction to reduce the risk of nerve damage.

Pontine Infarct Presenting as Peripheral Type Unilateral Facial Palsy

Acute peripheral facial palsy usually manifests Bell's palsy of unknown cause, and rarely lacunar infarct which located in facial nucleus can mimic peripheral facial palsy. A 73 year-old man with isolated facial asymmetry diagnosed with lacunar infarction which selectively involve the facial fascicles which lie in inferolateral aspect of pons. Clinicians should take into account the possibility of central lesion and brain stem infarction, even when patients present with isolated peripheral type facial palsy.

Randomized controlled clinical trial of 2 types of hydroxyapatite-coated implants on moderate periodontitis patients

PURPOSE: The aim of this study was to compare and analyze the peri-implant tissue conditions and prospective clinical outcomes associated with 2 types of hydroxyapatite (HA)-coated implants: (1) fully HA-coated implants and (2) partially HA-coated implants with resorbable blast medium on the coronal portion of the threads. METHODS: Forty-four partially edentulous patients were randomly assigned to undergo the placement of 62 HA-coated implants, and were classified as the control group (partially HA-coated, n=30) and the test group (fully HA-coated, n=32). All patients had chronic periodontitis with moderate crestal bone loss around the edentulous area. The stability and clinical outcomes of the implants were evaluated using the primary and secondary implant stability quotient (ISQ), as well as radiographic, mobility, and peri-implant soft tissue assessments around the implants. The Wilcoxon signed-rank test and the Mann-Whitney test were used to evaluate differences between and within the 2 groups, with P values 0.05). No significant differences were found in the survival rate (group I, 100%; group II, 100%) or the success rate (group I, 93.3%; group II, 93.8%). The fully HA-coated implants also did not significantly increase the risk of peri-implantitis (P>0.05). CONCLUSIONS: The fully HA-coated implants did not lead to an increased risk of peri-implantitis and showed good retention of the crestal bone, as well as good survival and success rates. Our study suggests that fully HA-coated implants could become a reliable treatment alternative for edentulous posterior sites and are capable of providing good retention of the crestal bone.

A clinical evaluation of botulinum toxin-A injections in the temporomandibular disorder treatment / 대한악안면성형재건외과학회지

BACKGROUND: This study clinically evaluated the effect of botulinum toxin type A (BTX-A) in the temporomandibular disorder (TMD) treatment using Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD). METHODS: A total of 21 TMD patients were recruited to be treated with BTX-A injections on the bilateral masseter and temporalis muscles and were followed up by an oral and maxillofacial surgeon highly experienced in the TMD treatment. For each patient, diagnostic data gathering were conducted according to the RDC/TMD. Characteristic pain intensity, disability points, chronic pain grade, depression index, and grade of nonspecific physical symptoms were evaluated. Wilcoxon signed-rank test was applied for statistical analysis. RESULTS: The results showed that more than half of the participants (85.7 %) had parafunctional oral habits such as bruxism or clenching. In comparison between pre- and post-treatment results, graded pain score, characteristic pain intensity, disability points, chronic pain grade, and grade of nonspecific physical symptoms showed statistically significant differences after the BTX-A injection therapy (p < 0.05). Most patients experienced collective decrease in clinical manifestations of TMD including pain relief and improved masticatory functions after the treatment. CONCLUSIONS: Within the limitation of our study, BTX-A injections in masticatory musculatures of TMD patients could be considered as a useful option for controlling complex TMD and helping its associated symptoms.

Minimal invasive horizontal ridge augmentation using subperiosteal tunneling technique / 대한악안면성형재건외과학회지

BACKGROUND: The goal of this study was to retrospectively evaluate the prognosis of minimal invasive horizontal ridge augmentation (MIHRA) technique using small incision and subperiosteal tunneling technique. METHODS: This study targeted 25 partially edentulous patients (10 males and 15 females, mean age 48.8 ± 19.7 years) who needed bone graft for installation of the implants due to alveolar bone deficiency. The patients took the radiographic exam, panoramic and periapical view at first visit, and had implant fixture installation surgery. All patients received immediate or delayed implant surgery with bone graft using U-shaped incision and tunneling technique. After an average of 2.8 months, the prosthesis was connected and functioned. The clinical prognosis was recorded by observation of the peri-implant tissue at every visit. A year after restoration, the crestal bone loss around the implant was measured by taking the follow-up radiographs. One patient took 3D-CT before bone graft, after bone graft, and 2 years after restoration to compare and analyze change of alveolar bone width. RESULTS: This study included 25 patients and 39 implants. Thirty eight implants (97.4 %) survived. As for postoperative complications, five patients showed minor infection symptoms, like swelling and tenderness after bone graft. The other one had buccal fenestration, and secondary bone graft was done by the same technique. No complications related with bone graft were found except in these patients. The mean crestal bone loss around the implants was 0.03 mm 1 year after restoration, and this was an adequate clinical prognosis. A patient took 3D-CT after bone graft, and the width of alveolar bone increased 4.32 mm added to 4.6 mm of former alveolar bone width. Two years after bone graft, the width of alveolar bone was 8.13 mm, and this suggested that the resorption rate of bone graft material was 18.29 % during 2 years. CONCLUSIONS: The bone graft material retained within a pouch formed using U-shaped incision and tunneling technique resulted with a few complications, and the prognosis of the implants placed above the alveolar bone was adequate.

PURPOSE: The purpose of the study was to identify factors affecting the innovative behavior of general hospital professional staff. METHODS: In the final analysis, the study focuses on the 442 structured questionnaires received from the professional staff (doctors, nurses, medical technicians, and administrative staff) of H Hospital, a public medical foundation. Data were collected from August 1 to 31, 2014. The SPSS/WIN 19.0 program was used for data analysis which included t-test, ANOVA, Scheffe test, Pearson correlation coefficients, and multiple regression analysis. RESULTS: Multiple regression showed that factors affecting innovative behavior of hospital professional staff were conditional reward, innovation-oriented culture, education, and job (Adj R2=.317). CONCLUSION: The results of this study suggest that it is necessary for the leader to demonstrate leadership with innovation and transaction in harmony to cultivate innovative behavior in hospital staff. Also, positive support and role in the hospital organization are fundamental to developing the strengths that each type of culture possess on the basis of the organizational culture of hospital, enabling hospital staff to exhibit their best voluntary innovative behavior.

Evaluation of subjective satisfaction of dental implant patients

OBJECTIVES: The goal of this study was to estimate the overall satisfaction level of dental implant patients and further evaluate factors influencing satisfaction. MATERIALS AND METHODS: Self-administered questionnaires were mailed to patients who received dental implant therapy at Seoul National University Bundang Hospital (Seongnam, Korea) from October 2003 to April 2005. The main portion of the questionnaire was shared to evaluate the level of satisfaction with implant therapy. The questionnaires contained evaluations of influencing factors, which were classified as pain-related, service-related, and complication-related. RESULTS: The responses from 93 patients (41 males, 52 females) with a total of 325 implants were included in the analysis, and the mean score for overall satisfaction level with implant therapy was 8.26. Female patients showed higher visual analogue scale (VAS) scores for both pain during (P=0.000) and after implant surgery (P=0.016). Male patients showed more 'negative' values for the reasonability of treatment cost (P=0.008) and the adequacy of the treatment period (P=0.022). CONCLUSION: The subjective satisfaction of patients was influenced by various factors, especially complication-related factors.

A comparison study of hygiene status in meals for poorly-fed children through microbiological analysis / 한국영양학회지

PURPOSE: The purpose of this study was to assess hygiene status of meals for poorly-fed children through microbiolo-gical quality. METHODS: Meals were provided by two social enterprises, one franchise, and one convenience store. There were a total of six meal samples; two samples (social enterprise meal 1; SEM 1, social enterprise meal 2; SEM 2) from two social enterprises, respectively, two samples (franchise meal 1; FM 1, franchise meal 2; FM 2) from one franchise, and two samples (convenience store meal 1; CSM 1, convenience store meal 2; CSM 2) from one convenience store. Microbiologi-cal analysis and assessment were performed by Korean food standards codex (KFSC). RESULTS: General bacteria and E. coli in SEM 1 were detected, but the levels were not over KFSC, and Coliform less than 9.2 x 10 CFU/g was also de-tected in seasoned bean sprouts of SEM 1. General bacteria was detected at 1.6 x 10(6) CFU/g in cabbage kimchi of SEM 2. Coliform was detected in cabbage kimchi, squid cutlet, stir-fried pork, and fried chicken of FM1 and 2, but the levels were not over KFSC. In addition, S. aureus was detected in cabbage kimchi and seasoned dried white radish of FM 1 and 2 (9.8 x 10(2) CFU/g, 9.4 x 10(3) CFU/g respectively), thus was over KFSC. B. cereus was detected in stir-fried pork and fried chicken (1.2 x 10(3) CFU/g, 1.5 x 10(3) CFU/g respectively) of FM 1 and 2, thus was over KFSC. Finally, S. aureus was detected in stir-fried dried squid, seasoned spicy chicken, and stir-fried kimchi of CSM 1 and 2, and was over KFSC too (9.5 x 10(4) CFU/g, 2.4 x 10(2) CFU/g, 1.3 x 10(3) CFU/g respectively). CONCLUSION: Results of this study suggest that systemic management of hygiene is necessary to safely providing meals to poorly-fed children.

Treatment of an Acute Mycotic Aneurysm of the Common Carotid Artery with a Covered Stent-Graft

We report herein a case successful endovascular treatment with a stent-graft of a rare case of rapidly growing mycotic aneurysm of the left common carotid artery due to acute bacterial endocarditis after eradication of the infection. Infected mycotic aneurysms of the peripheral vasculature have been considered as a contraindication for stent-graft implantation because of the possibility of microorganism spreading to the stent-graft; however, if there is evidence of complete eradication of microorganism and surgery is not an option, stent-graft implantation can be an effective and safe treatment modality for exclusion of the mycotic aneurysm.

Food-dependent exercise-induced anaphylaxis occurred only in a warm but not in a cold environment

Food-dependent exercise-induced anaphylaxis (FDEIA) is a type of exercise-induced anaphylaxis associated with postprandial exercise. We describe a 19-year-old man with FDEIA. Our patient complained of urticaria, angioedema, dizziness and hypotension associated with exercise after ingestion of walnut-containing foods in a warm environment. Skin prick test and prick to prick test were positive for walnut antigen. The attack didn't occur by free running outside for 10 min 2 h after taking walnuts, and the temperature was about

A Case of Familial Isolated Primary Hyperparathyroidism with a Novel Gene Mutation

Familial isolated primary hyperparathyroidism (FIHP) is an autosomal dominant disorder that is characterized by an early stage of either multiple endocrine neoplasia type 1 (MEN1) or hyperparathyroidism-jaw tumor (HPT-JT) syndrome. We report here on a case of a 42-years old woman who was diagnosed with papillary thyroid cancer and primary hyperparathyroidism. Her younger brother also had primary hyperparathyroidism. On the genetic analysis, they were both proven to have a novel frameshift mutation in the MEN1 gene (exon 10).
