The purpose of this study was to use as a basic data to develop suitable nursing intervention program and decide an appropriate intervention time after assessing shoulder range of motion in postmastectomy from 2 weeks to 3 month. 147 patients are chosen as study subject among patients who were in recovery of 2weeks, 1month, 2months and 3 months after surgical operation which is modified radical mastectomy. Data were collected at oncology medicine local and general surgery local in Seoul National University Hospital from May, 2003 to October, 2003. The range of motion of the shoulder(flexion, extension, abduction, internal rotation, external rotation) were examined. Analysis of data that shoulder range of motion average and standard deviation, percentage of the unaffected side and affected side compare with normal shoulder range of motion. Paired t-test was adopted to analyze the difference between affected side and unaffected side. Conclusion from this study is as following, 1. The most serious problem was external rotation (0.56%) and internal rotation is the next (19.9%) in 5 kinds of shoulder range of motion in 2 weeks after surgical operation 2. There was no difference in internal rotation after post operation 3 months but there were differences and shown to recover more than 90% in flexion and abduction. Also shoulder function incresed in flextion less than 80% and more than 80% in external rotation. As this study finding was shown that shoulder range of motion did not get back perfectly except of internal rotation and extension in point of 3 months after breast cancer surgical operation. External rotation was specially shown the lowest result so it is needed to exercise for improving their physical functioning recovery in postmastectomy patients. And it is suggested to study for helping to postmastectomy patients' physical and psycosocial functions with the early rehabilitation program which is based on these results.

Objectives : This study was carried out to determine whether the state anxiety may affect sleep on the night before surgery. Methods : The researcher examined the clinical charts of patients who were scheduled to receive surgery by general anesthesia the following day and then had semistructural interview with patients. In addition Spielberger's State Anxiety Inventory(1972), presleep questionnaire and postsleep questionnaire were administered to the patients. One hundred patients who responded to the questions were divided into three groups based on the state anxiety scores; low(n=35), middle(n=27) and high(n=38). Demographic and clinical characteristics of patients, some possible factors affecting sleep, daytime status and nighttime sleep before surgery were compared among three groups. Results : 1) There was no significant difference in demographic characteristics and some possible factors affecting sleep on the night before surgery among three groups. 2) In terms of clinical characteristics, the expectancy of surgical result was significantly different among three groups. More patients in low anxiety group than in middle and high anxiety groups, predicted surgical results as good, while more patients in middle and high anxiety groups than in low anxiety group could not predict their surgical results. 3) For daytime status, high anxiety group felt more tired compared to low anxiety group, but there was no significant difference in daytime nap among three groups. 4) For nighttime sleep before surgery, high anxiety group expected poor sleep and in fact, waked more frequently during sleep than low anxiety group. However there was no difference in bed time, sleep latency, rise time, total sleep time, sleep depth and sleep quality among three groups. 5) The need for hypnotics was higher before bedtime and also after rise in high anxiety group compared to low anxiety group. Conclusions : These results indicate that the individuals with high state anxiety before surgery have poor sleep and furthermore suggest that anxiolytics and/or hypnotics may be required to decrease anxiety and improve sleep for those with high state anxiety.

Background: There has been controversy over the prevalence of recoarctation in infants treated by subclavian flap aortoplasty(SFA) for coarctation of the aorta. To assess the rate of recurrence of coarctation after SFA, we reviewed the surgical results of SFA in infants with coarctation of the aorta. Material and method: Between 1986 and 1998, a total of 25 patients less than 1 year of age(12 neonates and 13 infants) underwent SFA for aortic coarctation. Age at operation was 3.0$\pm$3.0 months(mean $\pm$ standard deviation); mean weight was 5.0$\pm$1.4kg. Classic SFA was performed in 20 patients, reversed SFA in 2 patients, subclavian artery reimplantation in 2 patients and the combined resection-flap aortoplasty in one. Result: The aortic clamping time ranged from 20 to 88 minutes(mean 35.8 minutes). There were one operative death and two late deaths. There was no case of paraplegia or left arm ischemia in complications. Twenty-one(84%) of 24 hospital survivors were followed for 26.0$\pm$24.0 months. The risk of recoarctation in neonates(33.3%) was a little greater than infants(25.0%) without statistical significance. Conclusion: This study revealed that SFA resulted a relatively high incidence of recarctation in infants. It is desirable to select other methods of surgical treatment(combined resection-flap aortoplasty, extended end-to-end repair etc.) for severe isthmic coarctation or hypoplasia of the distal aortic arch in infants, instead of choosing SFA indiscriminately.

Objectives : The purpose of this study was to determine whether electroacupuncture(EA) is effective in reducing pain on the severe ankle sprain classified as grade 3 in rats. Methods : The severe(grade 3) ankle sprain model was induced surgically by ankle ligament injury(the anterior talofibular, the calcaneofibular and the posterior talofibular) in the Sprague-Dawley rats(180~250 g). The effects of EA on weight bearing forces(WBR) of the affected foot were examined in a rat model of ankle sprain. EA was applied to either SI6, ST37, GB34, GB39 or GB42 acupoints by trains of electrical pulses(2 Hz, 1 ms pulse width, 2 mA intensity) for 15 min. Results : Cutting of the lateral ankle ligament complex produced the severe ankle sprain symptoms as grade 3. EA of the contralateral SI6 resulted in more analgesic effect than one of ipsilateral SI6 even though there was significant effect. EA of the ipsilateral GB34 and GB39 produced potent analgesic effects on the surgical ankle sprained pain behaviors. However, there were no significant analgesic effects in the contralateral GB34 and GB39 EA groups. In addition, both side of ST37 and GB42 did not result in analgesic effect on the surgical ankle sprained rat. Conclusions : The data suggest that EA induced analgesia shows point specificity on the severe ankle sprained pain model classified as grade 3.

The calcifying odontogenic cyst was identified as a pathological entity by Gorlin & his associates in 1962. This lesion is one of the rarest and most disputable cysts in the oral region. The calcifying odontogenic cyst has variable clinical and radiological features. We review the previous literatures and report 2 cases of calcifying odontogenic cyst at Department of Oral and Maxillofacial Surgery, Kyung-Hee University. The 1st case was as follows. The patient vas 22 year old female. The past dental history revealed extraction of prolonged retained #73 tooth about 15days ago. She complained a painful swelling on the lower anterior teeth area. There were chin and vestibular swelling on the lower anterior teeth area, tenderness and missing of #33 tooth. The radiograph revealed well-demarcated unilocular radiolucency containing radiopaque calcific flecks around impacted #33 tooth. The clinical diagnosis was COC, so surgical enucleation was done. There was no recurrence and COC was confirmed by pathologist. The second case was as follows. The patient was 72 year old male. The past history revealed inactive tuberculosis, bronchial asthma and denture construction. The chief complaint was rapidly growing mass on the lower left anterior edentulous area. The clinical findings were chin swelling protruding mass with surface ulceration, fluctuation and a few bloody fluid in aspiration. The radiograph revealed well-demarcated radiolucency mimiking the residual cyst. The biopsy result was COC. The surgical excision was done, but the lesion was recurred 10 months later. The treatment was surgical excision with aggressive peripheral bone grinding and FTSG form groin area. There was no problem during the postoperative period.

Keratoacanthoma is a benign, self-limited epithelial lesion that closely resembles Squamous cell carcinoma(SCC). Keratoacanthoma occur primarily exposed skin in male patients over 45 years of ages. although etiology is unknown, sunlight, genetic, and human papillomavirus factor have been considered. in clinical feature, rapid enlargement occurs over 4$\sim$8 weeks, resulting ultimately in a hemispheric, firm, elevated, asymptomatic nodule that contains a central plug of keratin. When fully developed, the keratoacanthoma contains a core of keratin surrounded by a concentric collar of raised skin. Over the next 4$\sim$8 weeks, static lesion persists. Then undergoes spontaneous regression over the next 6$\sim$8weeks period by expulsion of the keratin core with resorption of the mass. In histologic feature, Keratoacanthoma consists of hyperplastic squamous epithelium growing into the underlying connective tissue. The surface is covered by a thickened layer of parakeratin with central plugging. Epithelium cell shows dysplastic features and the margins the normal adjacent epithelium is elevated. The differential diagnosis includes SCC. Keratoacanthoma present as a exophytic lesion with horny keratin occupying a depression on the top of the lesion, persists static period and undergoes rapid growth compared with SCC. Keratoacanthoma is usually treated by surgical excision or curettage of the base, spontaneous regression does not occur in every case. A 60 years old male who present facial lesion visit our hospital and surgical excision was done. Biopsy result was keratoacanthoma. We report case with review of literatures.

Background: Oronasal/antral communication, loss of teeth and/or tooth-supporting bone, and facial contour deformity may occur as a consequence of maxillectomy for cancer. As a result, speaking, chewing, swallowing, and appearance are variably affected. The restoration is focused on rebuilding the oronasal wall, using either flaps (local or free) for primary closure, either prosthetic obturator. Postoperative radiotherapy surely postpones every dental procedure aimed to set fixed devices, often makes it difficult and risky, even unfeasible. Regular prosthesis, tooth-bearing obturator, and endosseous implants (in native and/or transplanted bone) are used in order to complete dental rehabilitation. Zygomatic implantology (ZI) is a valid, usually delayed, multi-staged procedure, either after having primarily closed the oronasal/antral communication or after left it untreated or amended with obturator. The present paper is an early report of a relatively new, one-stage approach for rehabilitation of patients after tumour resection, with palatal repair with loco-regional flaps and zygomatic implant insertion: supposed advantages are concentration of surgical procedures, reduced time of rehabilitation, and lowered patient discomfort. Cases presentation: We report three patients who underwent alveolo-maxillary resection for cancer and had the resulting oroantral communication directly closed with loco-regional flaps. Simultaneous zygomatic implant insertion was added, in view of granting the optimal dental rehabilitation. Conclusions: All surgical procedures were successful in terms of oroantral separation and implant survival. One patient had the fixed dental restoration just after 3 months, and the others had to receive postoperative radiotherapy; thus, rehabilitation timing was longer, as expected. We think this approach could improve the outcome in selected patients.

Purpose : The purpose of study was to identify to analysis of core nursing interventions performed by Operating Room nurses. Method : The subjects of the study were arbitrarily selected nurses(n=104) working in Operating Room. The period for data collection was 15 days from July, 15, 2002 to July, 30. 2002. The instrument for study was 486 Nursing Interventions Classification developed by McClosky & Bulechek(2000) and was translated into Korean. In 486 nursing interventions, 57 nursing interventions were selected by more than half of 47 professional nurses group of Operating Room. 57 nursing interventions were used as a secondary questionnaire. In the secondary questionnaire, labels and definitions of all 57 interventions were listed. The collected data were self reported by Operating Room nurses. The data were analysed with SPSS program. Result : In 57 nursing interventions, the 'Behavior' domain was the most frequently used. Core interventions of Operating Room were performed several times a day by more than 50% of Operating Room nurses. Core interventions of Operating Room were 16 Core interventions, 7 classes, 5 domains. In the core interventions, the 'Physiological:Complex' domain was the most frequently used. Core interventions of Operating Room were Surgical Preperation, Infection Control:Intraoperative, Surgical Precautions, Fall Prevention, Documentation, Surgical Assistance, Environmental Management:Safety, Skin Surveillance, Physical Restraint, Pressure Ulcer Prevention, Environmental Management:Comfort, Infection Protection, Presence, Emotional Support, Specimen Management, Shift Report. Conclusion : Core interventions of Operating Room have implications for nursing care practice, nursing education, nursing research, and nursing information system in Operating Room.

Purpose : To evaluate the effect of surgical treatment of ligature-induced peri-implantitis in dogs using fractal analysis. Also, the capabilities of fractal analysis as bone analysis techniques were compared with those of histomorphometric analysis. Materials and Methods : A total of 24 implants were inserted in 6 dogs. After a 3-months, experimental periimplantitis characterized by a bone loss of about 3 mm was established by inducing with wires. Surgical treatment involving flap procedure, debridement of implants surface with chlorhexidine and saline (group 1), guided bone regeneration (GBR) with absorbable collagen membrane and mineralized bone graft (group 2), and $CO_2$ laser application with GBR (group 3) were performed. After animals were sacrificed in 8 and 16 weeks respectively, bone sections including implants were made. Fractal dimensions were calculated by box-counting method on the skeletonized images, made from each region of interest, including five screws at medial and distal aspects of implant, were selected. Results : Statistically significant differences in the fractal dimensions between the group 1($0.9340{\pm}0.0126$) and group 3($0.9783{\pm}0.0118$) at 16 weeks were found (P<0.05). The fractal dimension was statistically significant different between 8($0.9395{\pm}0.0283$) and 16 weeks in group 3 (P<0.05). These results were similar with the result of the evaluation of new bone formation in histomorphometric analysis. Conclusions : Treatment of experimental peri-implantitis by using $CO_2$ laser with GBR is more useful than other treatments in the formation of new bone and also the tendency of fractal dimension to increase relative to healing time may be a useful means of evaluating.

A 63-year-old male who had subtotal gastrectomy for early gastric cancer three months ago underwent Tc-99m bone scintigraphy for the evaluation of skeletal metastases. He had no symptoms such as fever, tenderness, or wound discharge. On physical examination, the surgical scat along the midline of the upper abdomen had keloid formation and there was no radiographic evidence of calcification. Bone scintigraphy (Fig. 1A & 1B) demonstrated all unusual linear increased uptake along the midline of the upper abdomen that corresponded to the,skin incision for subtotal gastrectomy. Usually, an incisional scar will not be visualized in Tc-99m methylene diphosphate (MDP) scintigraphy beyond two weeks after surgery.$^{1)}$ Upon reviewing the literature, there were only a few reports where localization of Tc-99m MDP in surgical scars were found two months after surgery.$^{2)}$ It was also reported that a few cases with Tc-99m MDP uptake in the keloid scar developed after surgery. Although there are several potential mechanisms that may explain the uptake of Tc-99m MDP in scar tissue, the primary mechanism in older scars is suggested to be a result of pathological calcification.$^{2)}$ Siddiqui et al$^{3)}$ suggested it could be due to microscopic calcification in small resolving hematomas. However, the primary mechanism in keloid scar is not well-known. We should obtain oblique or lateral views to differentiate the uptake in healing surgical scars from the artifactual uptake.
