  • The nose, a striking features of the human face, is regarded by many clinicians as the keystone of facial esthetics. Clinically, as the treatment of a dentofacial deformity, the soft tissue changes that occurred normally with movement of the skeletal bases. Changes of the soft tissue in the maxillary orthognathic surgery are widening of alar base, elevated nasal tip and flattening of upper lip. In addition, soft tissue change is difficult to predict, it has considerable variability in the response of soft tissue. We reviewed patients who received Le Fort I advancement osteotomy in our department and analysed preoperative and postoperative alar base width, nasal height in clinical measurement and cephalometry and patient's satisfaction of postoperative nasal appearance.

  • This study was performed to investigate the soft tissue changes around single implant-supported crowns during followup periods. Twenty patients(31 implants) whose single missing tooth in the maxillary anterior region had been replaced with an single implant-supported crown were recruited for the study. Crown length, soft tissue level and papilla height at the single implant-supported crowns were measured at follow-up examination and calculated from the slides taken at time of crown placement. as well Papilla index was scored from the slides taken at the time of crown placement and follow-up examination. A very little amount of recession occurred and the soft tissue level moved more apically and the papilla height increased significantly (p<0.01). Especially, both mesial and distal papilla index at single implant-supported crowns increased significantly during follow-up periods (p<0.001). When the two slides taken at the time of crown placement and follow-up were compared simultaneously, except one site, papillae size increased at all sites. From the results of the study, the interdental papillae at the single implant-supported crowns seemed to regenerate significantly and their crown margins were stable during follow-up periods. Hence it is indicated that various surgical interventions at on early stage to enhance soft tissue esthetics arourd single implants may be unnecessary.

  • Due to the long training time and high training cost of traditional surgical training methods, the emerging virtual surgical training method has gradually replaced it as the mainstream. However, the virtual surgical system suffers from poor authenticity and high computational cost problems. For overcoming the deficiency of these problems, we propose an optimized model for the local compression deformation of soft tissue. This model uses a simulated annealing algorithm to optimize the parameters of the soft tissue model to improve the authenticity of the simulation. Meanwhile, although the soft tissue deformation is divided into local deformation region and non-deformation region, our proposed model only needs to calculate and update the deformation region, which can improve the simulation real-time performance. Besides, we define a compensation strategy for the "superelastic" effect which often occurs with the mass-spring model. To verify the validity of the model, we carry out a compression simulation experiment of abdomen and human foot and compare it with other models. The experimental results indicate the proposed model is realistic and effective in soft tissue compression simulation, and it outperforms other models in accuracy and real-time performance.

  • In October 2021, soft rot disease seriously affected radish crop in Dangjin, Chungcheongnam-do, Korea. The infected radishes were stunted and turned dark green, with yellowish leaf foliage. A slimy, wet, and decayed pith region was observed in the infected roots. The bacterial strain KNUB-03-21 was isolated from infected roots. The biochemical and morphological characteristics of the isolate were similar to those of Pectobacterium brasiliense. Phylogenetic analysis based on the sequences of the 16S rRNA region and the concatenated DNA polymerase III subunit tau (dnaX), leucine-tRNA ligase (leuS), and recombinase subunit A (recA) genes confirmed that the isolate is a novel strain of P. brasiliense. Artificial inoculation of radish with P. brasiliense KNUB-03-21 resulted in soft rot symptoms similar to those observed in infected radish in the field; subsequently, P. brasiliense KNUB-03-21 was reisolated and reidentified. To our knowledge, this is the first report of P. brasiliense as a causal pathogen of radish soft rot in Korea.

  • In the Goesan region, located in Chungcheongbuk-do, Korea, a significant outbreak of soft rot infections was documented in August 2021, affecting fruits of Momordica charantia, commonly known as bitter melon or bitter gourd. The symptoms included a noticeable transition to yellowing in the affected fruits, eventually leading to their collapse. The bacterial strain KNUB-09-21 was isolated from the diseased fruits. Molecular analysis, using the sequences of the 16S rRNA region and three housekeeping genes (dnaX, recA, and leuS), along with the results of compound utilization in the API ID 32 GN system, provide strong evidence for the identification of the isolate KNUB-09-21 as Pectobacterium brasiliense. The pathogenicity of strain KNUB-09-21 on M. charantia was confirmed through a controlled inoculation test. Within two days, inoculated fruits displayed soft rot symptoms closely resembling those observed in naturally affected fruits. This is the first report of soft rot on M. charantia in Korea.

  • The aims of this study were firstly to investigate soft tissue reactions around single implant-supported crowns and secondly to compare soft tissue dimensions and conditions of the crowns in relation to interdental papillae, and lastly to investigate patients'esthetic satisfaction with their single implant-supported crowns according to the interdental papillae presence/absence. Twenty-nine patients (41 implants) whose single missing tooth in the maxillary anterior region had been replaced by single implant-supported crown participated for the study and various variables of soft tissue conditions, dimensions and crown dimensions were measured around the single implant-supported crowns at clinical examination and from study models and slides. The results showed that the soft tissue conditions around the single implantsupported crowns were similar to those around implants used for partially or totolly edentulous patients. Except for the high frequency of bleeding on probing, all other parameters revealed healthy conditions. The buccal sites of the crown had a shallow pocket comparing with other sites. At all sites of the crown, similar status of little inflammation was found. Mesial sites and central-incisor positioned implantsupported crowns had lower contact point position than distal sites and lateral-incisor positioned crowns, respectively. Mucositis index, probing depth and contact point position were significantly correlated with papillae index(p < 0.05). More inflammation and lower contact point position were found at the implant-supported crown with no interdental space than that with interdental space. Patients showed high esthetic satisfaction regardless of interdental space presence. The result indicated that, despite of their submucosal crown margins, single implantsupported crowns have soft tissue conditions as good as other implants used for the treatment of the different types of edentulism and a clinician can manipulate interdental papilla height by modifying crown shapes within the limits of not violating total esthetics.

  • This investigation was undertaken to know how soft tissue facial profile could be changed with age. The 3 serial lateral cephalometric roentgenograms of the twenty nine boys and twenty six girls between 9 and 13 years of age were studied and the findings seemed to warrant the following conclusions. 1. The author made the tables of means, standard deviations in each item, sex, age. 2. Soft tissue facial angle, soft tissue facial convexity including the nose tended to increase, but others tended to remain relatively stable. 3. Facial soft tissue thickness increased with age and the growth of facial soft tissue in the middle region (point A, LS, LI) was greater than others in the facial region. 4. In the soft tissue vertical proportions, G1'-Sn/Sn-Me' was 1.1, Sn-St/St-Me' was 0.51:1, Sn-LI/LI-Me' was 0.82:1 and those were stable with age.

  • Objectives : This study aimed to evaluate adverse outcome associated with acupotomy and compare it with that of acupuncture. Methods : We retrospectively analyzed the chart records of 71 patients who received acupotomy at Daemyung Korean medical clinic from January 7, 2020 to March 6, 2020. We divided the acupotomy treatment area into 10, including the head, hand, chest, knees, shoulders, low back, neck, upper extremities, thighs, and feet. Furthermore, we investigated the adverse effect of acupotomy on those areas after treatment. Data were analyzed using descriptive statistics, and frequency analysis. Results : 'Bruise of specific region' accounted for the largest portion with 29 cases, followed by 24 cases of 'feeling tired and sleepy' and 17 cases of 'itch'. There were 16 cases of 'sustained pain' at the area of treatment, 11 cases of 'fatigue', 5 cases of 'swelling', 5 cases of 'dizziness', 4 cases of 'hematoma'. There were 3 cases of 'vertigo' and 2 cases of 'parathesia' and 'wide bruises', 'headache', 'gastric discomfort', 'bleeding', and 'skin rash' each. There was one case each that experienced 'unclear pronunciation', 'nausea', 'abnormal sweating', 'vomiting' and 'emotional/psychological reactions'. Conclusions : Adverse outcomes associated with acupotomy were mostly 'bruise of specific region', 'feeling tired and sleepy', 'itch', 'sustatained pain', and 'fatigue'. However, no adverse outcome or irreversible damage that have a serious effect on the body were observed.

  • Background: Acupotomy is a type of acupuncture where a scalpel-shaped needle (miniscalpel needle) is used instead of a normal acupuncture needle to exfoliate adhesion sites or to relax entrapped regions. This study aimed to identify the descriptive characteristics of patients who received acupotomy treatment at a single Korean Medicine Clinic. Methods: This retrospective review analyzed the medical charts of patients who had received acupotomy at least once from August 2017 to December 2019 at a single Korean Medicine Clinic. The demographic characteristics, chief complaints, acupotomy treatment sites, and principal diagnosis codes were analyzed. Results: We identified 551 outpatients; the average age was 52 ± 14.26 years and 49.9% were male. The patients underwent an average of 8.47 sessions of acupotomy. Altogether, 35.91% of the acupotomy treatments were administered to the spinal regions, of which 60.01% were in the lumbar region. The codes related to the lumbar spinal condition/disease which were used most frequently. The chief complaints were dizziness, lumbar spinal stenosis, and Dupuytren's contracture in patients over 60 years of age. Conclusion: This is the 1st analysis of acupotomy treatment patterns in Korea to date. Acupotomy is primarily administered in the treatment of spinal conditions/diseases, especially for those involving the lumbar region. Future studies are necessary to determine the clinical outcomes of patients who receive acupotomy treatment and the safety of this treatment.

  • Elbow hygroma and hypertrophic osteodystrophy were diagnosed in Doberman referred to Veterinary Teaching Hosptial of Chungbuk national University. Physical examination, plain radiography, and bone scan were performed in the patient. The radiography revealed soft tissue swelling on the caudal region of the elbow and irregular radiolucent zone involving the metaphysis subjacent and parallel to the distal radial and ulnar physes. The bone scan of the forelimbs revealed increased uptake in region where the soft, fluid-filled mass on the elbow was present. But the radiolucent areas (the distal radial and ulnar physes) were seen normal bone uptake. Therefore, hypertrophic osteodystrophy ruled out the diagnosis. $^{99m}Tc-MDP$ scan is suitable to routine clinical use for soft tissue inflammation and bone lesions detection.
