PURPOSE: The purpose of this study was to examine the effects of a neonatal nursing practice program for nursing students on students' stress, self-efficacy, and confidence. METHODS: A 1-group pre- and post- study design was used. The participants consisted of 64 nursing students who were in a pediatric nursing clinical practicum at a nursing college in Seoul from September 2015 to May 2016. The program consisted of 3 stages-orientation, practice, and debriefing-and was conducted for 3 hours during a 2-week period of the pediatric nursing clinical practicum. The dependent variables were neonatal nursing practice stress, self-efficacy, and confidence. Data were analyzed using the paired t-test, the Pearson correlation coefficient, the x² test, and descriptive statistics with SPSS for Windows version 22.0. RESULTS: The neonatal nursing practice program was effective at decreasing clinical practice-related stress and increasing confidence and self-efficacy regarding neonatal nursing practice. CONCLUSION: The neonatal nursing practice program may effectively promote the integration of theoretical knowledge and practice. In the future, we propose to develop various educational programs that reinforce basic nursing skills for neonates as part of an effective pediatric nursing clinical practicum.

OBJECTIVE: The aim of this study was to evaluate pulp and periodontal changes following rapid tooth retraction by periodontal distraction after bone undermining surgery in young adult dogs. METHODS: After extraction of second premolars, the interseptal bone mesial to the upper 3rd premolar was undermined. After activating the distraction appliance at 0.5 mm/day for six days, the dogs were sacrificed at 0, 1, 3, 5, 7, and 9 weeks during the consolidation period. Tissue changes of periodontium and pulp were evaluated radiologically, histologically, and immunohistochemically. RESULTS: Digital subtraction radiography showed active bone formation in the stretched periodontal ligament from 0 - 4 weeks. Resorption of the alveolar bone, appearance of osteoclasts, and infiltration of inflammatory cells were observed just after the activation period at the pressure side, and distinctive bone formation was seen in the tension side of the periodontal ligament from 1 week. New bone formation was active at 1 - 3 weeks. The expression of calcitonin gene-related peptide in the experimental group was increased at the alveolar bone and pulp, and periodontal ligament at the pressure side from 0 - 1 week, and it decreased after 5 weeks to become similar to that of the control group. CONCLUSIONS: The results showed that rapid tooth movement using periodontal distraction can be new form of orthodontic tooth movement for accelerating normal bone formation.

OBJECTIVES: The purpose of this study was to examine the effect of problem-based learning (PBL) on dental education to dental students. The following were investigated in this study: 1. Does PBL improve the ability of self-directed learning? 2. Does PBL change communication ability? 3. Does PBL change the strategy of problem solving? METHODS: The participants of this study were 39 students in the experimental group and 68 students in the control group. The measurement tools of this study were self-directed learning, communication, and problem solving abilities tests designed by the Korean Educational Development Institute. The data was analyzed by the two-way ANOVA and ANOVA with repeated measures. RESULTS: In self-directed learning ability during 3 semesters, the experimental group showed a U-shape change but the control group showed a reverse U-shape change. In the experimental group, the self-directed learning ability was decreased after one year (after the first and second semester). The level of communication ability decreased every day during the three semesters monitored in both the control and experimental groups. The level of communication ability in the experimental group continuously decreased during the three semesters, with the exception of one semester. Finally, for the problem solving ability during the three semesters, the experimental group showed a reverse U-shape change while the control group showed a U-shape change. In the experimental group, there was no change after two semesters. CONCLUSIONS: On the basis of the findings in this study, the following conclusions can be made. First, problem-based learning has a positive educational effect compared to didactic-based learning within one year. Second, the appropriate length of PBL is two semesters, or one year. It could be recommended that dental education in Korea should be combined or hybridized with PBL; for example, PBL could be used in combination with brief lectures or block lectures by teachers.

The superior gluteal artery perforator flap technique has increasingly been used for soft tissue defects in the sacral area following its introduction nearly 25 years ago. Advantages in covering sacral defects include muscle sparing, versatility in design, and low donor side morbidity. The bilateral superior gluteal artery perforator flap procedure is planned in cases of large sacral defects that cannot be covered with the unilateral superior gluteal artery perforator flap. Here, we report two cases of large sacral defects in which patient factors of poor general health, such as old age, pneumonia, and previous operation scar, led to use of a large unilateral superior gluteal artery perforator super-flap with parasacral perforator. The approach was utilized to reduce the operation time and prevent unpredictable flap failure due to the large flap size. Even though the parasacral perforator was included, the versatility of the large superior gluteal artery perforator flap was preserved because sufficient perforator length was acquired after adequate dissection.

PURPOSE: Skin graft may fail for a number of reasons. Hematoma or seroma formation prevents graft adherence. Traditionally tie-over dressing has been used in skin graft fixation, but skin graft in convex and narrow place like fingers or toes, tie-over dressing is hard to be applied. And Vaseline gauze over graft often adheres to graft by exudate into gauze fibers and hardening, and may cause damage to graft in dressing change. We report successful results of using silicone net dressing in fixation of split thickness skin graft over these place. METHODS: After skin graft, the silicone net, Mepitel(R) (Molnlycke Health Care, Box 13080, SE-402 52 Goteborg, Sweden) was applied over the graft followed saline wet gauze dressing in 25 patients. 13 cases were on finger, 8 cases were on foot or toes, 4 cases were on anterior chest. RESULTS: In 22 cases, there were no hematoma or seroma formation, Mepitel(R) maintained 5 days after skin graft. And then, Mepitel(R) was removed from the graft. In 3 cases, there were hematoma formation, Mepitel(R) was removed at 3 days after skin graft. In all cases, grafts were taken well without maceration or skin eruption. CONCLUSION: The silicone net, Mepitel(R), is dressing material made of silicone gel bound to a pliable polyamide net, and it can provide uniform pressure to the graft, even in convex and narrow place. And net like structure allows the exudates of the wound to pass freely into the secondary absorbent dressing and easier to remove from the grafts than Vaseline gauze. We think that the use of a Mepitel(R) is a efficient tool for securing skin grafts.

Scalp and calvarium defects are caused by trauma, burn, tumor resection, or congenital diseases. We experienced a few cases of severe electrical burn of scalp and calvarium, but fourth-degree contact burn of scalp and calvarium is a rare case. A 67 years old man was presented with a 25% total body surface area contact burn. A 20 cm×15 cm thick eschar on the patient's scalp was observed. Among various techniques for scalp reconstruction, we planned fasciocutaneous transposition flap with split thickness skin graft for coverage of large defect. Considering aesthetically satisfactory outcome, we designed a fasciocutaneous transposition flap including the hair-bearing areas. We additionally used skin graft for uncovered surrounding areas. There were no flap necrosis, graft loss, or any other surgical complications after the surgical flap and skin graft. At 6-month follow-up, the operation site was stable. The patient satisfied with functional and aesthetical outcomes, so we report this case.

Volume deficiency and poorly defined cupid's bow of the upper lip are frequently encountered problems in secondary cleft lip deformities. In this report, we present the method of a periumbilical dermal graft for correcting secondary cleft lip deformity. A 17-year-old male patient presented with a poorly defined notching cupid's bow and volume deficiency of the upper lip. He had undergone cleft lip surgery when he was 2 years old. We planned to perform a periumbilical dermal graft. There were sufficient amount of periumbilical subdermis and fat tissue thickness to obtain abundant volume. The periumbilical contour was similar to the natural contour of the lip. Less scarring was expected. There was no need to change the posture during operation, making it easy to harvest. Postoperative evaluations showed vermilion symmetry. Ideal cupid's bow shape and position were achieved without color mismatch. As a result, we obtained an ideal volume of the upper lip. Therefore a periumbilical dermal graft is a good option for correcting volume deficiency of the lip with good aesthetic outcomes.

PURPOSE: Instant noodle is one of the most popular noodle and its consumption is increasing annually. So scalding burns caused by Instant noodle are comparatively common. Instant noodle can lead to contact burn caused by noodle as well as scalding burn by soup. Because the depth of the burn can be deeper than general scalding burn, it can cause physical or psychological disability and the medical and social expense is not a few. The purpose of this study was to investigate the epidemiology and clinical features of the scalding burn caused by Instant noodle. METHODS: Retrospective research was conducted 165 patients with scalding burn by Instant noodle among patients admitted to our burn medical center from May 2011 to April 2016. Subjects were classified by age, gender, affected site and degree and treatment method. RESULTS: For 6 years, 165 subjects went through hospital treatment because of the scalding burn by Instant noodle. It consisted of 48 infants, 74 children and adolescence, and 43 adults. The average TBSA (total body surface area, %) was 3.43. The number of patients exceeding 10% were 3. The most common affected site was thigh in 35.5% and there was no big differences between each age group. 8 patients did operations and 6 did dermabrasion. CONCLUSION: From May 2011 to April 2016, about 7% of total scalding burn patients was injured by Instant noodle. Considering the characteristics of scalding burn by Instant noodle, conservative treatment was preferred to surgical treatment. 149 of total 165 patients were done conservative treatment using cultured allogenic keratinocytes.

Although low temperature contact burn doesn't have clear definition, it is used to describe the burn occurred by long time exposure under 50℃ temperature. 4(th) degree burn can be occurred by low temperature contact burn because of low pain, especially in patients who are insensitive to stimulation by various reasons. The under-floor heating system such as Ondol or electronic heating pad is popular in Korea because of the cultural influence. Although the upper limit surface temperature of electronic heating pad is 50℃, severe burn injury can happen by long time exposure. So we report a low temperature contact burn case of 4(th) degree involving gluteus maximus muscle of the buttock caused by electric heating pad, which led to Rhabdomyolysis.
