KIM, JEONGEUN,KIM. SUKWHA,KIM, HEE-CHAN,KIM, KYUNG-HWAN,YANG, SEOK-CHUL,LEE, CHOON-TAEK,KONG, HYOUN-JOONG,LEE, KYUNGSOON Lippincott Williams Wilkins 2012 Computers, informatics, nursing Vol.30 No.12

<P> Through the use of ubiquitous health, or u-Health, services, medical information can be adapted and made accessible via computer and Internet to provide quality healthcare to anybody, any place, and any time. We developed and implemented u-Health services for patients with chronic obstructive pulmonary disease and studied their experiences with respect to their knowledge of chronic obstructive pulmonary disease and skill and attitude toward the u-Health devices. The u-Health services were composed of telemonitoring and teleconsultation supplemented with home visits. To determine its effectiveness, the u-Health service system was implemented for 2 years with 144 chronic obstructive pulmonary disease patients in a clinical experiment. The subjects were divided into three experimental groups, each provided with different services, compared before and after intervention, and among groups. The analysis of data gathered through the system suggested that u-Health services can support patients with chronic obstructive pulmonary disease, improve patients’ knowledge about chronic obstructive pulmonary disease self-management, build u-Health device usage skills, and foster a positive attitude toward u-Health devices. The u-Health services for the chronic obstructive pulmonary disease patients were both feasible and effective from the patients' perspective. </P>

Accelerated Development of the First and Second Mandibular Molars After Distraction Osteogenesis of the Mandible in Patients With Hemifacial Microsomia

Kim, Sukwha,Park, Jong Lim,Baek, Seung-Hak,Chung, Ji-Hyuk,Kim, Jae Chan,Park, Chul Gyoo Mutaz B. Habal, MD 2009 JOURNAL OF CRANIOFACIAL SURGERY - Vol.20 No.3

Although distraction osteogenesis of the mandible in patients with hemifacial microsomia (HFM) before the mixed dentition period is widely performed, long-term follow-up information on dental problems is limited. We evaluated the long-term effect of distraction osteogenesis on dental development by comparing Nolla's developmental stages of the first and second molars between the affected and unaffected sides of the mandible. Forty-five patients with unilateral HFM who received distraction osteogenesis of the mandible between the ages of 5 and 8 years and whose dental status was followed for more than 2 years were selected for this study. The patients were divided into 2 groups: group I (n = 28) consisted of patients with Pruzansky types I and IIA and group II (n = 17) consisted of patients with types IIB and III. Panoramic radiographs at T0 (1 month before distraction), T1 (6 months to 1 year after distraction), T2 (2-3 years after distraction) were reviewed. Nolla's stages for the first and second molars were compared at each of the abovementioned times between the affected and unaffected sides using Wilcoxon signed-rank test. In group I, there was no differences observed in Nolla's stages of the first and second molars in comparisons between the affected and unaffected sides of the mandible. However, in group II, at T0, there was a significant difference in Nolla's stage of the first and second molars in comparisons between the affected and unaffected sides. Over time, tooth development was accelerated, and eventually, there was no difference in Nolla's stage between the affected and unaffected sides at T1 and T2. Patients with severe HFM can benefit from distraction osteogenesis of the mandible. The results of this study showed that this procedure could normalize the delayed development and eruption of the first and second molars.

Dynamic Reconstruction of the Philtrum Using Coronal Muscle Splitting Technique in Microform Cleft Lip

Kim, Sukwha,Kwon, Juyong,Kwon, Geun-Yong,Choi, Tae Hyun by Mutaz B. Habal, MD. 2014 JOURNAL OF CRANIOFACIAL SURGERY - Vol.25 No.3

PURPOSE: The philtral column and dimple are especially important in patients with cleft lip. Recently, we have found that, at maximal puckering, the appearance of the philtrum worsens although the philtral column is well formed at rest. In this study, we explore the effectiveness of the coronal muscle splitting technique in a microform cleft lip through comparative analysis of the postoperative results between the control group (patients without coronal muscle splitting) and the study group (patients with coronal muscle splitting). METHODS: Philtral reconstruction was performed in 24 patients with microform cleft lip between March 2006 and March 2010. The philtrum was reconstructed in 12 patients using the coronal muscle splitting technique and in the other 12 patients without this technique.The convexity of the philtral column and the dimpling of the philtrum were evaluated at rest and at maximal puckering through digital photographs and videos taken preoperatively and postoperatively. In addition, we compared the postoperative results between the 2 groups using the paired t-test. RESULTS: Postoperative evaluation was done at 6 to 48 months (mean, 25 mo). There was no statistically significant difference in the shape of the philtral column and the philtral dimple between the 2 groups preoperatively (P > 0.05).Reconstruction of the philtral column in the study group rendered better results than in the control group at both rest and maximal puckering (P < 0.001 and P < 0.001). Reconstruction of the philtral dimple in the study group rendered better results than in the control group at both rest and maximal puckering (P = 0.018 and 0.035). CONCLUSIONS: The coronal muscle splitting technique offers more esthetic and functional results in the formation of the philtral column and dimple both at rest and at maximal puckering than in the control group in cases of philtral reconstruction of the microform cleft lip.

Furlow 구개성형술을 이용한 점막하 구개열의 교정

김석화,김지혁,김진환,이윤호 大韓成形外科學會 2000 Archives of Plastic Surgery Vol.27 No.2

Furlow's palatoplasty has been used as the primary treatment for cleft palate. From 1991 to 1999, 24 submucous cleft palate patients underwent Furlow's palatoplasty. The follow-up period was 3 months to 8 years(mean 24 months). Patients were selected after a thorough study for velopharyngeal insufficiency including intraoral examination, speech assessment, digital subtraction radiography(DSR). Postoperatively velopharyngeal function was reevaluated with speech assessment and digital subtraction radiography in the 7 cooperative patients. Speech parameters including hypernasality, nasal emission, and Allison scale were improved after surgery. Digital subtraction radiography provided the value of velopharyngeal gap and the degree of the motion of lateral pharyngeal wall, both of which were improved after surgery. Furlow's palatoplasty has advantage such as no impairment of nasopharyngeal physiology, no harmful effect on the hard palate and the realignment of the levator muscle which plays important role on the movement of the soft palate. The results show that a Furlow's palatoplasty can satisfactorily correct velopharyngeal insufficiency in carefully selected submucous cleft palate patients.

김인건,김진환,오갑성,김석화 大韓成形外科學會 1991 Archives of Plastic Surgery Vol.18 No.6

열성 유전형 이영양성 표피수포증에서 생긴 심한 수부기형을 수술로 교정하여 좋은 결과를 얻었으며 이를 위해서는 수술전후 환자의 전처치(total care)와 질병에 대한 교육이 필요하며 수술로 표피고치를 장갑벗기듯이 조심스럽게 벗기면 쉽게 제거되고(epidermal degloving), 구축을 완전히 펴지도록 하며 피부이식술과 적절한 고정이 필요하다. 술후 장기간 부목을 착용시키고, 능동적 운동을 계속하며, 마찰로 물집이 생기지 않게 예방하는 조치를 게을리 하지 않아야 한다. Epidermolysis bullosa refers to a group of whose primary common feature is the formation of skin blisters following trivial trauma. Although any of dystrophic or scarring types of epidermolysis bullosa may produce hand deformities, the recessve type produces the most severe and characteristic hand deformity-adduction contracture of the thumb, volar contractures of the palm and digits, and a pseudosyndactyly in an epidermal cocoon. The advanced hand deformity needs surgical therapy and the understanding of the pathomechanics of the development of the hand deformity is essential for the effective treatment. The objective of the hand reconstruction is to reestablish elementary pinch and grasp by the release of adduction contracture of the thumb and the palmar contracture and resurfacing by skin graft. A patient with recessive dystrophic epidermolysis bullosa is described, who had serious hand disability. The surgical correction of the hand deformity, dressing with biobrane, and the appication of the splint improved hand function.

Self-Assembling Peptide Nanofibers Coupled with Neuropeptide Substance P for Bone Tissue Engineering

Kim, Su Hee,Hur, Woojune,Kim, Ji Eun,Min, Hye Jeong,Kim, Sukwha,Min, Hye Sook,Kim, Byeung Kyu,Kim, Soo Hyun,Choi, Tae Hyun,Jung, Youngmee Mary Ann Liebert 2015 Tissue engineering. Part A Vol.21 No.7

<P>The number of patients requiring flat bone transplantation continues to increase worldwide. Cell transplantation has been successfully applied clinically; however, it causes another defect site and the time requirements to harvest cells and expand them are considerable. In this study, KLD12/KLD12-SP (KLD12+KLD12-substance P [SP]) was designed to mimic endogenous tissue-healing processes. The structures of KLD12, KLD12-SP, and KLD12/KLD12-SP were observed by transmission electron microscopy and circular dichroism spectra. KLD12/KLD12-SP nanofibers (5-10?nm) were created under physiological conditions by formation of a β-sheet structure. The ability of mesenchymal stem cells (MSCs) to recruit KLD12/KLD12-SP was observed by using an in vivo fluorescence imaging system. Labeled human bone marrow stromal cells supplied via an intravenous injection were recruited to the scaffold containing KLD12/KLD12-SP. Polylactic acid/beta-tricalcium phosphate (PLA/β-TCP) scaffolds filled with KLD12/KLD12-SP were applied to repair calvarial defects. The composite constructs (groups: defect, PLA/β-TCP, PLA/β-TCP/KLD12, and PLA/β-TCP/KLD12/KLD12-SP) were implanted into rat defect sites. Bone tissue regeneration was evaluated by observing gross morphology by hematoxylin and eosin and Masson's trichrome staining at 12 and 24 weeks after surgery. Gross morphology showed that the defect site was filled with new tissue that was integrated with host tissue in the KLD12/KLD12-SP group. In addition, from the staining data, cells were recruited to the defect site and lacunae structures formed in the KLD12/KLD12-SP group. From these results, the PLA/β-TCP+KLD12/KLD12-SP composite construct was considered for enhancement of bone tissue regeneration without cell transplantation.</P>

Effects of the long-term use of maxillary protraction facemasks with skeletal anchorage on pharyngeal airway dimensions in growing patients with cleft lip and palate

Jung-Eun Kim,Sunjin Yim,Jin-Young Choi,Sukwha Kim,Su-Jung Kim,Seung-Hak Baek 대한치과교정학회 2020 대한치과교정학회지 Vol.50 No.4

Objective: To investigate the effects of the long-term use of a maxillary protraction facemask with miniplate (FM-MP) on pharyngeal airway dimensions in growing patients with cleft lip and palate (CLP). Methods: The study included 24 boys with CLP (mean age, 12.2 years; mean duration of FM-MP therapy, 4.9 years), divided into two groups according to the amount of A point advancement to the vertical reference plane (VRP): Group 1, > 4 mm; Group 2, < 2 mm; n = 12/group. After evaluating the skeletodental and airway variables using lateral cephalograms acquired before and after FM-MP therapy, statistical analyses were performed. Results: Group 1 showed greater forward and downward displacements of the posterior maxilla (posterior nasal spine [PNS]-horizontal reference plane [HRP]; PNSVRP), greater increase in ANB, more forward tongue position (tongue tip-Pt vertical line to Frankfort horizontal plane), and greater increase in the oropharynx (superior posterior airway space [SPAS]; middle airway space [MAS]) and upper nasopharynx (PNS-adenoid2) than did Group 2. While maxillary advancement (A-VRP and PNS-VRP) correlated with increases in SPAS, MAS, and PNS-adenoid2, downward displacement of the PNS (PNS-HRP) correlated with increases in SPAS, MAS, PNSadenoid1, and PNS-adenoid2, and with a decrease in vertical airway length (VAL). Mandibular forward displacement and decrease in mandibular plane correlated with increases in MAS. Conclusions: FM-MP therapy had positive effects on the oropharyngeal and nasopharyngeal airway spaces without increases in VAL in Group 1 rather than in Group 2. However, further validation using an untreated control group is necessary.

The effect of biphasic calcium phosphate and demineralized bone matrix on tooth eruption in mongrel dogs

Lee, Si Woo,Kim, Ji-Young,Hong, Ki Yong,Choi, Tae Hyun,Kim, Byung Jun,Kim, Sukwha Korean Cleft Palate-Craniofacial Association 2021 Archives of Craniofacial Surgery Vol.22 No.5

Background: Bone grafts can provide an optimal environment for permanent tooth to erupt and enhance the stability of the alveolar maxilla. Although autologous bone is an optimal source for osteogenesis, its inevitable donor site morbidity has led to active research on bone substitutes. This study was designed to evaluate the safety and feasibility of using biphasic calcium phosphate (BCP; Osteon) as a bone substitute in dogs. Methods: Bilateral third and fourth premolars of four 15-week-old mongrel dogs were used. All teeth were extracted except the third premolar of the right mandible, which was used as a control. After extraction of the premolars, each dog was administered BCP (Osteon), demineralized bone matrix (DBM; DBX), and no graft in the hollow sockets of the right fourth premolar, left fourth premolar, and left third premolar, respectively. Radiographs were taken at 2-week intervals to check for tooth eruption. After 8 weeks, each dog was sacrificed, and tooth and bone biopsies were performed to check for the presence of tooth and bone substitute particle remnants. Results: Four weeks after the operation, permanent tooth eruptions had started at all the extraction sites in each dog. Eight weeks after the operation, all teeth had normally erupted, and histological examination revealed BCP particles at the right fourth premolar. Conclusion: In all four dogs, no delay in the eruption of the teeth or shape disfigurement of permanent teeth was observed on gross inspection and radiologic evaluation. On histological examination, most of the BCP and DBM were replaced by new bone. Bone substitutes can be used as graft materials in patients with alveolar clefts.
