Garre's osteomyelitis is associated with bacterial infection and bone necrosis resulting from obstruction of blood supply. The most common cause for Garre's osteomyelitis is odontogenic infection that originates from periodontal tissue or dental pulp. Subperiosteal abscess may also cause Garre's osteomyelitis in the progress of the infection. Mandible is more often affected than maxilla, most commonly in the permanent first molar region of mandible. Clinically, it results in a hard swelling over the jaw, producing facial asymmetry. Meanwhile, radiograph shows a characteristic feature of irregular pulpal cavity, showing new periosteal proliferation located in successive layers to the condensed cortical bone on stimulated site. The treatment method for Garre's osteomyelitis are removal of the infection source, root canal treatment, antibiotic medication, and incision and drainage. This report presents a case of Garre's osteomyelitis under 15 years old. The patient was successfully treated by antibiotic medication accompanied with root canal treatment. Since the symptom of pediatric patients is less severe than adult, careful diagnosis with history taking and clinical examination is necessary. Furthermore long-term follow-up examination is needed to prevent recurrence even after the symptom disapears.

Purpose: The aim of this study is to evaluate the flexural strength of flexible resins and the flexibility of different resin splint (RS) systems in comparison with resin wire splint (RWS) system. Materials and methods: Three different resin materials (G-aenial flo, GA, GC; Superbond, SB, Sun medical; G-fix, GF, GC) were tested flexural strength test in accordance with ISO-4049:2000. For the flexibility test of splint systems, a artificial model with resin teeth was used to evaluate three types of resin splint systems (GA, SB, and GF) and one resin wire splint system. The left central incisor was simulated 'injured teeth' with third degree mobility. Three consecutively repeated measurements of periotest value were taken in horizontal direction, before and after splinting to access tooth mobility. The splinting effect was calculated through the periotest value. Differences were evaluated through One-way Anova and Tukey HDS post-hoc tests for pair-wise comparison (${\alpha}=.05$). Results: Although GA group showed significant higher flexural strength than SB and GF groups, all of three different resin splint systems produced a significantly higher and rigid splinting effect compared with 016" resin-wire splint system (P < .05). Conclusion: Within the limits of an in vitro study, it can be stated that resin splint systems are too rigid and may not be acceptable to treat tooth avulsion.

The application of sealants is a highly technique-sensitive procedure, requiring an extremely dry field prior to placement. Moisture contamination of the etched enamel surface before sealant placement is cited as the main reason for sealant failure. The purpose of this study was to evaluate the effects of different methods of sealant application on the shear bond strength of sealants to enamel. In groups 1, 2, 3, 4 Teethmate(unfilled sealant) was used, while Ultraseal XTplus(filled sealant) was used in groups 5, 6, 7, 8. Groups 1 and 5(control) were acid etched for 15 seconds using 35% phosphoric acid, washed and then dried. In groups 2, 6 drying agents were applied, and in groups 3, 7 bonding agents were applied and light cured. In groups 4 and 8 both drying agent and bonding agent were applied. Then sealant was cured to the specimen using molds 3mm in diameter and 2mm in height. Thermocycling was performed and shear bond strength was finally measured. The following results were obtained : 1. Groups using filled sealant(groups 5, 6, 7, 8) showed higher shear bond strengths compared to groups using unfilled sealant(groups 1, 2, 3, 4). 2. Among groups using unfilled sealant(groups 1, 2, 3, 4), groups 2, 3, 4 showed significantly higher shear bond strength compared to group 1(p<0.05). There were no significant differences among groups 2, 3 and 4. 3. There were no significant differences(p>0.05) among groups using filled sealant(groups 5, 6, 7, 8). 4. When modes of fracture were examined, cohesive failure was observed in groups 2, 3 and 4.

Purpose: This study was performed to evaluate the operative results of osteochondritis dissecans treated with autogenous osteochondral grafts. Materials and Methods: From May 1990 to May 2000, this study included 13 patients, 17 cases treated with autogenous osteochondral grafts. The mean age of patients at operation was 23.4 years (range,20 to 32 years), all cases were men, and the mean follow-up was for 24.2 months (range, 12 to 110 months). Treatment was done by open or arthroscopic method using with Osteochondral Autograft Transfer System (OATS, Arthrex, USA). Results: Trauma history existed in all cases, and major trauma history in 7 cases, and minor repetitive in 10 cases. The involved sites of lesion were medial femoral condyle in 11 cases, in which extended classic site was 9 cases, inferocentral site was 2 cases, and lateral femoral condyle in 6 cases, in which all cases were inferocentral site. Magnetic resonance imaging (MRI) staging was stage II in 1 case, stage III in 11 cases, stage IV in 5 cases, and arthroscopic staging was stage III in 12 cases, stage IV in 5 cases. The mean lesion size was 3.19$cm^2$ (range, 1 to 8$cm^2$). Clinical results evaluated with grading system by Aichroth, were excellent in 3 cases (18$\%$), good in 11 cases (65$\%$), moderate in 2 cases (12V), poor in 1 case (5$\%$), which revealed satisfactory results in 83$\%$. Congruent articular surface, satisfactory articular thickness, and no loosening or subsidence was evidenced by follow-up MRI or arthroscopic finding. Conclusion: Autogenous osteochondral grafts can be an alternative treatment in lesions larger than 1$cm^2$ in size, unstable lesion, and involvement of weight-bearing articular surface. Long term follow-up will be needed for the final efficacy of autogenous osteochondral grafts.

Purpose: This study aimed to investigate the influence of post-traumatic stress on professional quality of life as mediated by cognitive emotion regulation among nurses working in small and medium hospitals who have experienced violence and to develop and test a structural equation model of that professional quality of life. Methods: Participants were 215 nurses who had experienced violence working in medium and small hospitals. They were surveyed using a structured questionnaire. Results: The final model was shown to have good fit with χ² (2.83), GFI (.90), TLI (.90), and CIF (.90). Therefore, the model was selected as the final model, supporting 7 of the 11 hypotheses. Post-traumatic stress, adaptive emotional regulation, and maladaptive emotional regulation had significant impacts on empathy satisfaction (professional quality of life subscale) and empathy fatigue (subscale of professional life quality) among nurses who had experienced violence, and the explanatory power of these variables was 28.7% and 38.6%, respectively. Conclusion: In the development of nursing intervention programs to improve the professional quality of life of nurses who have experienced violence, factors such as post-traumatic stress and cognitive emotion regulation (adaptive and maladaptive) should be considered as they were identified in this study as influencing the professional quality of life of such nurses in medium and small hospitals.

Objectives : This study was performed to evaluate the effects of PTSD on memory function, to investigate the difference of memory function between PTSD and non-PTSD patients, and to identify major variables correlated to PTSD scale and Memory Assessment Scale. Methods: The authors used PTSD-scale(Mississippi scale and Combat Exposure Scale) for measuring PTSD severity. And, Beck Depression Inventory was also used. Memory assessment scale was assessed by well trained psychologist. Thirty one Vietnam veterans who had been hospitalized were collected consecutively. These patients were evaluated by psychiatrists with interview and measurement for fifteen months since March, 1997. The collected data were analyzed by SPSS and the stastistic methods used for analysis Chi-square, t-test, and Pearson's correlation. Results : 1) There were significant differences in short-term memory and verbal memory between PTSD and non-PTSD in Vietnam veterans. 2) Mississippi scale and Combat Exposure Scale were negatively correlated to short-term memory and verbal memory(Pearson's correlation). 3) Religion status was a significant variable between PTSD and non-PTSD in Vietnam veterans. 4) There is no significant difference in visual memory and total memory scale between PTSD and Non-PTSD in Vietnam veterans Conclusions : Neuropsychological changes were found in the posttraumatic stress disorder. There were significant differences in short-term memory and verbal memory between PTSD and non-PTSD in Vietnam veterans. Mississippi scale and Combat Exposure Scale were negatively correlated to short-term memory and verbal memory. We suggest that neuropsychological test might be used for an objective assessment of patients with the combat related PTSD and be considered helpful in the assessment of patients with the diagnosis. And we also suggest rehabilitation strategies would be used to compensate for memory deficits in PTSD patients.

A fistula between the respiratory and gastrointestinal systems is generally caused by infection and trauma. We experienced a 51-year old man with a broncho-pleuro-gastro-colonic fistula. He complained of chronic foul odor during respiration. He had suffered a traumatic diaphragmatic rupture 30 years ago. The infection of the diaphragm caused necrosis of the right lower lobe of the lung. It also caused a broncho-pleural fistula. The infection also created adhesion and a perforation of the gastric cardiac portion and the colonic splenic flexus portion of the gastro-intestinal track. We performed left lower lobectomy of the lung, reconstruction of the diaphragm and gastro-intestinal reanastomosis.

Mucocele is clinical term used to describe swelling caused by the pooling of saliva at the site of a severed or obstructed minor salivary gland duct. Mucoceles are categorized into two subgroups, extravasation type and retention cyst type. The etiology of extravasation type mucocele is related to mechanical trauma to the minor salivary gland excretory duct, resulting in extravasation of mucus into the fibrous connective tissue so that a cyst-like cavity is produced, but the epithelial lining is absent. Retention cyst type mucocele results from obstruction of minor salivary gland excretory duct, and cystic cavity is lined by epithelial cells. This case report presents a mucocele occurred on the lower lip, and caused by suture silk unremoved for 3 years. Suture silk penetrated and tore the minor salivary gland duct on the lower lip with subsequent extravasation of mucus into the fibrous connective tissue.

Purpose : The purpose of this study was to investigate the effect of the perceived nursing work environment (NWE) on person-centered critical care nursing (PCCN) practices among nurses in intensive care units (ICUs). Methods : A cross-sectional research design was adopted for this study; participants were 126 ICU nurses working in five hospitals in B city. From December 2018 to February 2019, a survey questionnaire on NWE and PCCN were conducted. The collected data were analyzed with a multiple hierarchical regression analysis. Results : The mean score for NWE was $2.98{\pm}0.39$. Among the factors, basic work system was the highest ($3.39{\pm}0.41$), followed by leadership of the head nurse ($3.31{\pm}0.55$), interpersonal relationships ($2.77{\pm}0.62$), and institutional support ($2.58{\pm}0.52$). The mean score for PCCN was $3.52{\pm}0.46$. Among the factors, comfort was the highest ($3.77{\pm}0.62$), followed by respect ($3.55{\pm}0.56$), compassion ($3.43{\pm}0.60$), and individuality ($3.38{\pm}0.56$). The interpersonal relationship (${\beta}=.31$, p=.001) and the number of patients per shift (${\beta}=-.23$, p=.005) had a significant effect on PCCN, accounting for 25.9% of the total variance. Conclusion : These results suggest that it is necessary to enhance the relationship-oriented culture and reduce the workload of nurses in order to improve the quality of nursing care in ICUs.
