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.

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.

Carcinosarcoma is a biphasic tumor composed of an intimate admixture of epithelial and mesenchymal element, both of which are malignant. Primary cutaneous cases are extremely rare. There have been reported only 18 cases of cutaneous carcinosarcoma in the world and only one case can be found in the korean pathology literature. Therefore it has been difficult to characterize the clinical course of carcinosarcoma of the skin. We present a further case of primary cutaneous carcinosarcoma in a 86-years-old woman with exophytic and hemorrhagic mass on scalp. Histologic and immunohistochemical studies revealed both squamous cell carcinoma and spindle cell sarcomatoid change intermingled in the same tumor. The clinical and histologic findings of cutanous carcinosarcoma were described.

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.

It is known that cases of osteomyelitis are less common than 5% in deep burn cases. This research presents a case of chronic osteomyelitis, presented 7 years after initial electrical burn injury. A 43-year-old male patient was admitted to the Department of Plastic Surgery, suffering from an 22900-voltage electrical burn on right medial malleolus in 2010. There was no postoperative complication for five years observation. In November 2016, he was admitted to the Plastic Surgery department, suffering from the skin and soft tissue defect on right medial malleolus without trauma history. The osteomyelitis on the right medial malleolus was found in bone scintigraphy. The medial malleolus was covered with a local flap two days after admission. Dehiscence was found after surgery and exudate was emerged continuously from the flap site. We decided to cover the raw surface with a perforator based propeller flap 22 days after admission considering reconstructive ladder. The flap survived successfully, and partial epidermal sloughing was healed completely by daily dressing at 51 days after the surgery. It is advisable to establish and access the prudent plan before surgery through many kinds of radiological tests and physical examinations considering vascular stability and delayed wound healing.

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.

PURPOSE: Hair straightener is a common tool among various household electric appliances used for hair styling. Hair straightener has plate consists of metal or ceramic, which lead to possible burn if contacted. Main users of hair straightener are young women whereas main victims of hair straightener caused-burn are infants. Among patients visiting our burn medical center, the case of attending hospital due to contact burn by hair straightener tends to increase. METHODS: Retrospective research was conducted 72 patients with contact burn by hair straightener among patients admitted to our burn medical center from Jan 2012 to Dec 2014. Subjects were classified by age, gender, affected site and degree and treatment method. RESULTS: 72 subjects consisted of 39 infants, 9 children, adolescence and 24 adults. Affected sites were presented as hands in 31, face in 21, foot in 13, arms in 5 and legs in 2 subjects. Degree of burn was presented as deep second degrees in 67 and third degrees in 5 subjects; 70 subjects were cured through conservative treatment whereas 2 subjects had local flap. CONCLUSION: Contact burn by hair straightener can be ranged from partial to full thickness skin defect. It is important to note this kind of burn develops more frequently in infants and is preventative. Education for young women who use hair straightener is crucial. Training regarding function and design improvement of hair straightener is also essential. Uncovering the heated plate after use through a separate lock device might be great help for prevention of contact burn if developed.
