Comparison of Tooth Whitening Efficacy between Gel and Strip with Light Activator / 치위생과학회지

The study aimed to compare the whitening efficacy of a strip and gel containing 2.9% hydrogen peroxide, using a tooth whitening light activator. The whitening effect was compared through in vitro and in vivo studies. In the in vitro study, we used stained hydroxyapatite (HAP) specimens as artificial teeth. HAP specimens were made using HAP powder and polyvinyl alcohol solution, and stained by modified Stookey's method. A whitening gel and whitening strip were applied to the respective specimens for 20 minutes, with a light activator. The color changes were measured using a colorimeter. In the in vivo study, one group (test 1) used the gel with a light activator and the other group (test 2) used a strip with the same activator for 15 minutes a day, for four consecutive days. An organoleptic evaluation using a Vita shade guide and instrumental evaluation using a Shade eye-NCC (Shofu Co., Japan) were performed. The color change values (ΔE*) in the in vitro study revealed the strip with the light activator to be more effective than the gel with the same activator (p<0.001). In the in vivo study, even though there was no significant difference between the groups with respect to the ΔE*, using either the Shade eye-NCC or the Vita shade guide, the change in yellowness (Δb*) was statistically significant (p=0.024). In conclusion, test 2 group that used 2.9% hydrogen peroxide strip with a light activator, showed a tendency towards increased whitening than test 1 group that used the gel with the same activator; however further studies are needed to validate the above finding.

Effects of a whitening strip combined with a desensitizing primer on tooth color / 대한구강보건학회지

OBJECTIVES: The purpose of this study was to evaluate the efficacy of a 2.9% hydrogen peroxide (HP) whitening strip with a desensitizing agent as a primer. METHODS: This study was approved by the Institutional Review Board of Kyungpook National University Hospital. A total of 144 subjects (mean age: 21.7 years) were recruited after they provided informed consent for participation in the study. All participants used the whitening strip and primer for 1.5 h a day for 14 days. ShadeEye-NCC and Vita classical shade guide were used to determine the color changes, with respect to baseline, after 1, 3, 5, 7, and 14 days. A self-administered questionnaire was used to collect data on satisfaction after bleaching and irritating symptoms during the 14 days. All collected data were analyzed with repeated measures ANOVA and one-way ANOVA using SPSS 20.0 for windows. RESULTS: Brightness (ΔL*) was significantly higher in groups 2 and 3 than in the control group after 3 days of the experiment. Chroma (Δb*) started to decrease in groups 2 and 3, compared to control, after 1 day. Perceived symptoms of irritation were significantly lower in groups using the strip combined with the desensitizing primer than in the control group. Satisfaction after bleaching was higher in the experimental groups than in control. CONCLUSIONS: The HP whitening strip with a desensitizing agent as a primer is clinically effective in bleaching human enamel after 3 days of use. It also reduces the prevalence of gingival irritation.

Evaluation of In-Vitro Efficacy of Active Ingredients in Dentifrice Used for Different Treatment Times / 치위생과학회지

The purpose of this study was to evaluate the in-vitro efficacy of the active ingredients of dentifrice following treatment time. The whitening effect was evaluated by a change in lightness value relative to the contact time of hydrogen peroxide, by using artificially stained hydroxyapatite discs. The anti-calculus effect was assessed based on the amount of calcium eluted from the human dental calculus by sodium pyrophosphate. Remineralization was evaluated by the Vickers hardness test following the application of sodium fluoride to bovine enamel. In order to view dentinal tubules occlusion, the formation of insoluble calcium salts by bovine dentin specimens was observed using scanning electron microscopy. Change in lightness value (ΔL) was 5.50±1.51 after 1 min of treatment, 5.73±0.43 after 3 min, 8.64±0.24 after 10 min, 18.93±0.76 after 30 min, and 27.35±0.54 after 60 min. The amount of calcium eluted from the human dental calculus was 4.23±0.14 ppm after 1 min of treatment, 4.51±0.04 ppm after 3 min, 12.12±0.16 ppm after 10 min, 17.85±0.81 ppm after 30 min, and 25.15±0.32 ppm after 60 min. The Vickers hardness change value (ΔVHN) was 1.96±1.44 after 1 min, 1.52±1.06 after 3 min, 9.06±0.15 after 10 min, 10.83±5.13 after 30 min, and 12.55±2.09 after 60 min. Partial dentinal tubules occlusion was observed at 10 min and complete occlusion was evident at 60 min. In summary, the use of patch type dentifrices for 10, 30, or 60 min were 1.57 to 8.26 times more effective than using the paste type dentifrices for 1 to 3 min. Based on these findings, it is reasonable to expect that the use of patch type dentifrices for 10 min would lead to remineralization, anti-calculus and dentinal tubules occlusion effects, and that use for 30 min would result in a whitening effect.

Protective role of oligonol from oxidative stress-induced inflammation in C6 glial cell

BACKGROUND/OBJECTIVES: Natural products or active components with a protective effect against oxidative stress have attracted significant attention for prevention and treatment of degenerative disease. Oligonol is a low molecular weight polyphenol containing catechin-type monomers and oligomers derived from Litchi chinensis Sonn. We investigated the protective effect and its related mechanism of oligonol against oxidative stress. MATERIALS/METHODS: Oxidative stress in C6 glial cells was induced by hydrogen peroxide (H2O2) and the protective effects of oligonol on cell viability, nitric oxide (NO) and reactive oxygen species (ROS) synthesis, and mRNA expression related to oxidative stress were determined. RESULTS: Treatment with oligonol inhibited NO and ROS formation under cellular oxidative stress in C6 glial cells. In addition, it recovered cell viability in a dose dependent-manner. Treatment with oligonol also resulted in down-regulated mRNA expression related to oxidative stress, nuclear factor kappa-B (NF-kappaB) p65, cyclooxygenase-2 (COX-2), and inducible nitric oxide synthase (iNOS), compared with the control group treated with H2O2. In particular, expression of NF-kappaB p65, COX-2, and iNOS was effectively reduced to the normal level by treatment with 10 microg/mL and 25 microg/mL of oligonol. CONCLUSIONS: These results indicate that oligonol has protective activity against oxidative stress-induced inflammation. Oligonol might be a promising agent for treatment of degenerative diseases through inhibition of ROS formation and NF-kappaB pathway gene expression.

Nomogram for Prediction of Prostate Cancer with Serum Prostate Specific Antigen Less than 10 ng/mL

Although prostate-specific antigen (PSA) is a very useful screening tool, prostate biopsy is still necessary to confirm prostate cancer (PCA). However, it is reported that PSA is associated with a high false-positive rate and prostate biopsy also has various procedure-related complications. Therefore, the authors have devised a nomogram, which can be used to estimate the risk of PCA, using available clinical data for men with a serum PSA less than 10 ng/mL. Prostate biopsies were obtained from 2,139 patients from January 1998 to March 2011. Of them, 1,171 patients with a serum PSA less than 10 ng/mL were only included in this study. Patient age, PSA, free PSA, prostate volume, PSA density and percent free PSA ratio were analyzed. Among 1,171 patients, 255 patients (21.8%) were diagnosed as PCA. Multivariate analyses showed that patient age, prostate volume, PSA and percent free PSA had statistically significant relationships with PCA (P < 0.05) and were used as nomogram predictor variables. The area under the (ROC) curve for all factors in a model predicting PCA was 0.759 (95% CI, 0.716-0.803).

Laparoscopic Ureteroneocystostomy: Modification of Current Techniques

PURPOSE: To review the feasibility of laparoscopic ureteroneocystostomy with extracorporeal eversion of the ureteral end in various distal ureteral lesions. MATERIALS AND METHODS: We conducted a retrospective review of 5 laparoscopic procedures of ureteroneocystostomy with extracorporeal eversion of the ureteral end. Of these, 4 patients (range, 45 to 54 years) had distal ureter stricture or obstruction after gynecological surgeries for endometriosis or a large uterine myoma. One patient (male, 67 years) had low-grade distal ureter cancer. The laparoscopic procedure was combined with cystoscopic insertion of a ureteral stent and extracorporeal eversion of the ureter through the 10-mm port on the affected side. RESULTS: The laparoscopic ureteral reimplantations with and without a psoas hitch in patients with distal ureteral lesions was successful in all patients. The mean operation time was 137 minutes (range, 104 to 228 minutes). Two patients underwent additional psoas hitch. In all patients, short-term success was confirmed by voiding cystourethrography and intravenous pyelography conducted 3 months after the operation. The mean follow-up of the entire group was 12 months (range, 3 to 30 months). We noted no major or minor complications over the follow-up period. CONCLUSIONS: The technique of laparoscopic ureteroneocystostomy for benign or malignant ureteral strictures continues to evolve. Surgeons should be versatile with various options and technical nuances when dealing with these cases. Simple modifications of laparoscopic ureteroneocystostomy with extracorporeal eversion of the ureteral end, nonreflux extravesical anastomosis, and simultaneous cystoscopy will be crucial to the ease of performance and a successful outcome.

Torsion of an Indirect Hernia Sac Causing Acute Scrotal Swelling in a Child

Torsion of a hernia sac is an extremely rare condition that presents as acute scrotum in children. We report a case of a 6-year-old boy who presented with an acute scrotum and was found during surgical exploration to have torsion of an indirect hernia sac associated with hydrocele. Upon scrotal exploration, deterioration of the scrotum due to inflammatory changes was found. A necrotic cyst was recognized within a communicating hydrocele of the scrotum and was twisted at an angle of about 360degrees. All urologists should be aware of this special condition in the differential diagnosis of acute scrotum.

Malignant Inflammatory Myofibroblastic Tumor of the Bladder with Rapid Progression

A 71-year-old man was referred for painless hematuria and a bladder tumor. Cystoscopy and computed tomography revealed a 3-cm oval nodular mass on the left lateral side of the bladder. The patient underwent a complete transurethral resection of the lesion and histology showed a proliferation of atypical spindle cells with inflammation consistent with a myofibroblastic tumor. After 4 and 7 months, follow-up cystoscopy demonstrated nodular mass lesions and transurethral resection of bladder tumor was done, which showed chronic cystitis and a recurred myofibroblastic tumor, respectively. Five months later, multiple lymph node, bone, and soft tissue metastases were found by positron emission tomography. The patient was treated first with palliative chemotherapy, including doxorubicin and cisplatin. After that, radiologic studies showed disease progression but the patient refused further treatment and died 6 months later.

Vesico-Appendiceal Fistula Misdiagnosed as Meckel's Diverticulum: A Laparoscopic Approach

A 26-year-old man complained of a vague low abdominal discomfort for the previous 2 months. Radiologic evaluations demonstrated that there was tubular structure connected with the right side wall of the bladder, suggesting Meckel's diverticulum with fistula formation to the bladder as well as a mass-like bladder wall thickening. With an impression of Meckel's diverticulum with fistula with the bladder, laparoscopic surgery was performed to confirm a diagnosis and to manage the Meckel's diverticulum with fistula with the bladder. The distal tip of the appendix was firmly attached to the right side of the bladder. The final diagnosis was corrected by laparoscopy followed by laparoscopic appendectomy and fistula repair. Vesico-appendiceal fistula is an uncommon type of vesico-enteral fistula and a rare complication of unrecognized appendicitis. Additionally, this report showed the significant value of laparoscopy as a diagnostic and therapeutic tool to this entity.

Primary Undifferentiated Penile Sarcoma in Adolescence

We report a case of primary penile undifferentiated sarcoma. A 16-year-old adolescent man visited Pusan National University Hospital complaining of a painless mass on his penis that was increasing in size. Magnetic resonance images revealed a 5x5-cm mass and pathological examinations revealed small round cell sarcomas with neuroendocrine differentiation. The tumor, which had metastatic pulmonary nodules, was treated by tumorectomy and systemic chemotherapy. Thirty-four months after the initial diagnosis, the patient was still alive without evidence of local recurrence or metastatic disease. This is our second case of an undifferentiated penile sarcoma.

Feasibility of ultrasound-guided posterior approach for interscalene catheter placement during arthroscopic shoulder surgery / 대한마취과학회지

BACKGROUND: Continuous interscalene block has been known to improve postoperative analgesia after arthroscopic shoulder surgery. This was a prospective study investigating the ultrasound-guided posterior approach for placement of an interscalene catheter, clinical efficacy and complications after placement of the catheter. METHODS: Forty-two patients undergoing elective arthroscopic shoulder surgery were included in this study and an interscalene catheter was inserted under the guidance of ultrasound with posterior approach. With the inplane approach, the 17 G Tuohy needle was advanced until the tip was placed between the C5 and C6 nerve roots. After a bolus injection of 20 ml of 0.2% ropivacaine, a catheter was threaded and secured. A continuous infusion of ropivacaine 0.2% 4 ml/hr with patient-controlled 5 ml boluses every hour was used over 2 days. Difficulties in placement of the catheter, clinical efficacy of analgesia and complications were recorded. All patients were monitored for 48 hours and examined by the surgeon for complications within 2 weeks of hospital discharge. RESULTS: Easy placement of the catheter was achieved in 100% of the patients and the success rate of catheter placement during the 48 hr period was 92.9%. Postoperative analgesia was effective in 88.1% of the patients in the post anesthetic care unit. The major complications included nausea (7.1%), vomiting (4.8%), dyspnea (4.8%) and unintended vascular punctures (2.4%). Other complications such as neurologic deficits and local infection around the puncture site did not occur. CONCLUSIONS: The ultrasound-guided interscalene block with a posterior approach is associated with a success high rate in placement of the interscalene catheter and a low rate of complications. However, the small sample size limits us to draw definite conclusions. Therefore, a well-designed randomized controlled trial is required to confirm our preliminary study.

Postoperative renal function in patients is unaltered after robotic-assisted radical prostatectomy / 대한마취과학회지

BACKGROUND: Pneumoperitoneum with an intra-abdominal pressure (IAP) of 14 mmHg is known to decrease renal function. Robotic-assisted radical prostatectomy (RARP) requires an IAP of more than 15 mmHg for operation. Therefore, we retrospectively investigated whether patients who underwent RARP experienced renal insufficiency during the postoperative period (at postoperative days 7 and 30). METHODS: One hundred patients who underwent RARP were enrolled in this study. Preoperative serum blood urea nitrogen (BUN) and serum creatinine (Cr) levels were measured. Creatinine clearance (CrCl) was calculated using the Cockcroft and Gault formula. CrCl was calculated at 1 day before surgery (baseline), 2 hr postoperatively, and at 1, 3, 7, and 30 days postoperatively (POD 1, POD 3, POP 7, and POD 30). Patients were assigned to abnormal CrCl (n = 52) or normal CrCl groups (n = 48) on the basis of these measurements. RESULTS: Significant inter-group differences in BUN, Cr, and CrCl were observed at all postoperative time points. BUN and Cr decreased significantly at postoperative 2 hr and POD 1, 3, and 7 versus baseline in both groups, whereas CrCl increased significantly at postoperative 2 hr and POD 1, 3, and 7 versus baseline in both groups. However, BUN, Cr, and CrCl were similar at POD 30 and preoperatively in the two groups. CONCLUSIONS: RAPR, which requires an IAP of 15-20 mmHg for more than 4 hr, does not induce renal dysfunction during the postoperative period, and even in those patients with an abnormal CrCl.

Risk Factors that Influence the Early Access Patency of an Arteriovenous Fistula in Hemodialysis Patients

PURPOSE: It is very important to obtain vascular access that resists repeated punctures and maintains an adequate blood flow for performing hemodialysis in patients with end stage renal disease. This study was designed to identify the risk factors that may influence the early patency rate of arteriovenous fistulas (AVFs). METHOD: We analyzed 304 cases of AVFs in 299 patients who underwent hemodialysis access surgery in our hospital from January 2000 to March 2007. The rate of early access failure and the risk factors of early access patency were evaluated retrospectively. RESULT: The rate of early access failure of an AVF was 14.5%. The early access failure group showed a higher incidence in women and in the patients with a previous history of ipsilateral central venous catheterization. Further examination by multivariate analysis demonstrated that a history of ipsilateral central venous catheterization was an independent risk factor for early access failure of AVFs. CONCLUSION: A history of ipsilateral central venous catheterization was an independent risk factor for early access failure of AVFs in this study.

Clinical Characteristics of Papillary Thyroid Microcarcinoma (PTMC) / 대한내분비외과학회지

PURPOSE: PTMC is defined as a papillary thyroid cancer smaller than 10 mm in its greatest diameter. It is the most common form of differentiated thyroid cancer and its prognosis is known to be very favorable. The aim of this study is to identify its biologic behavior and to formulate a reasonable therapeutic strategy for the treatment of PTMC. METHODS: 379 patients with papillary thyroid cancer were analyzed. Each patient was diagnosed preoperatively or postoperatively and treated between Jan. 2000 and Dec. 2007. Among these patients, 143 had been identified as having PTMC (37.7%) with a mean tumor size of 0.72 cm in diameter. RESULTS: There were no significant differences of the clinical characteristics such as gender, age, the operative methods, or multicentricity between the PTMC group and the non-PTMC group, except for LN metastases. Also, there were fewer symptoms of palpable neck mass and preoperative findings such as capsular invasion and microcalcification in the PTMC group. We performed unilateral lobectomy with or without central compartment neck node dissection for the early stage diseases, but for the later stages of disease we performed near-total or total thyroidectomy with routine central compartment neck node dissection. And for the patients with lateral node enlargement, we performed ipsilateral modified radical neck dissection (MRND). CONCLUSION: This study shows that PTMC is quite similar to conventional papillary thyroid cancer in its biological behavior, and we conclude that total thyroidectomy with central compartment neck node dissection is the proper therapeutic strategy to treat PTMC. However, further study is necessary for identifying the low-risk and high-risk patients with PTMC.

Diagnosis and Treatment of Malocclusions using the Invisalign System / 대한치과교정학회지

Recent developments in software technology have made it possible to create a virtual three-dimensional model of the dental arches from digitally scanned casts of a patient's dentition. This modelmay then be manipulated with software to produce stages of tooth movement from the initial malocclusion to the final desired occlusion. A sterolithograghic model is made for each stage of tooth movement which is the basis for construction of a series of clear and thin overlay appliances. These appliances are worn full time by the patient to move the teeth according to the programmed stages of movement. Malocclusions involving mild to moderate crowding and space closure have been proven to be successfully treated with this appliance. Experience with this appliance has demonstrated excellent patient compliance with less discomfort, improved esthetics and oral hygiene control, when compared with fixed orthodontic appliances. Orthodontic treatment with this appliance is a potentially useful alternative approach to fixed appliances for treatment of a variety of malocclusions in patients with fully erupted permanent teeth.

The Effects of the Self Efficacy Promotion and Exercise Training Program on Anxiety, Depression and Quality of Life of Kidney Transplant Recipients / 성인간호학회지

The purpose of this study is to develop and evaluate the Self Efficacy Promotion and Exercise Training Program to decrease anxiety and depression and to increase the quality of life for kidney transplant recipients. The subjects were selected randomly among the patients who underwent renal transplant at three major transplantation hospitals in Seoul, Korea. The observed subjects in this study consisted of 56 patients who had renal transplantations between one to twelve months prior to this study. The patients did not take any regular physical exercise. This study was carried out between November, 1999 and March, 2000. The study groups were divided into 3 groups; exercise training group (n=16), self efficacy group (n=18) and control group (n=22). The exercise training group received self efficacy promotion and exercise training program for 12 weeks. The self efficacy group received self efficacy promotion education, but no exercise training was given. The control group was not offered any education. The anxiety, depression and quality of life were evaluated 3 times, before the experiment, after 8 weeks and after 12 weeks. The data were analyzed with mean, standard deviation, Chi-square test, ANOVA and Scheff test. The results were as follows: 1. After the experiment, anxiety and depression scores of the exercise training group and self efficacy group were more significantly decreased than those of the control group (p=.05). 2. After the experiment, the quality of life score of the exercise training group and self efficacy group were more significantly increased than those of the control group (p=.05). This study showed that the Self Efficacy and Exercise Training Programs were effective. Therefore, it is expected that the Self Efficacy Promotion and Exercise Training Program could be widely applied as an effective independent nursing intervention to decrease anxiety and depression and to increase quality of life for kidney transplant recipients.

The Change of Muscle Strength, Muscle Endurance, Flexibility and Activities of Daily Living of the Kidney Transplant Recipients / 성인간호학회지

The purpose of this study was to explore the change of muscle strength, muscle endurance, flexibility and activities of daily living to develop a rehabilitational program. The subjects were selected randomly among the patients who underwent kidney transplantations at one major transplantation hospital in Seoul, Korea. This study was carried out between November 23, 1999 and February 15, 2000. The subjects in this study consisted of 16 patients who had kidney transplantations between 1 month and 12 months ago prior to this study. They were all on steroids and did not take any physical exercise regularly. The muscle strength, muscle endurance, flexibility and activities of daily living were evaluated at 1st week and after 12 weeks. The data were analyzed with numbers, percentiles, mean, standard deviation and t-test. The results were as follows: 1. After 12 weeks, the grip strength was significantly decreased than 1st week (p=.0002). 2. After 12 weeks, the back lift strength was significantly decreased than 1st week (p=.0002). 3. After 12 weeks, the muscle endurance was increased than 1st week, but it was not significant(p=.5487). After 12 weeks, the flexibility was significantly decreased than 1st week (p=.0002). 5. After 12 weeks, the activities of daily living was significantly decreased than 1st week (p=.0006). Like the above result, the kidney transplant receipients' muscle strength, flexibility and activities of daily living were reduced. In order to solve this problem, the writer has found that program development to prevent the defects should be extremely required. Since now on the number of patients should expand. After the kidney transplantation, the periods of 4, 8, 12 and 16 weeks are extended. The writer proposes to examine the different phase of change in each periods.

The Effect of the Self Efficacy Promotion and Exercise Training Program of Kidney Transplant Recipients / 간호학회지

This study was attempted to evaluate how the self efficacy promotion and exercise training program effect on the postoperative general conditions of transplant recipients after kidney transplantations. The subjects were selected randomly among the patients who underwent renal trans- plantations at three major transplantation hospitals in Seoul, Korea. This study was carried out between November 1999 and March 2000. The observed subjects in this study consisted of 56 patients. The exercise training group(n=16) received the self efficacy promotion and exercise training program for 12 weeks which contained general knowledge for compliance instruction, exercise training and self efficacy promotion education. The self efficacy group(n=18) received general knowledge for compliance instruction and self efficacy promotion education but no exercise training was given. The control group(n=22) were not offered any education. The knowledge for compliance, self efficacy, physical conditions(weight, muscle strength, muscle endurance, flexibility), lab studies (hemoglobin, creatinine, cholesterol), activities of daily living and quality of life were evaluated 3 times, before the experiment, at 8 weeks and at 12 weeks. The data were analyzed with mean, standard deviation, Chi-square test, ANOVA and Scheff test. The results were as follows: 1. The knowledge and self efficacy score of the exercise training group and self efficacy group were significantly increased than those of the control group(p=.0001). 2. The weight of the exercise training group was significantly decreased compared to those of the self efficacy group and the control group(p=.0001). Muscle strength (grip strength, back lift strength), and flexibility of all 3 groups were significantly changed(p=.0001). However, muscle endurance in all 3 groups showed no significant differences. 3. The hemoglobin level of the exercise training group and the self efficacy group were significantly increased compared to that of the control group(p=.0001) and the cholesterol levels of the exercise training group and the self efficacy group were significantly decreased compared to that of the control group(p=,0001). However, the creatinine levels in all 3 groups showed no significant differences. 4. The activities of daily living scores of the exercise training group was significantly increased than that of the control group (p=.0003), and the quality of life scores of the exercise training group and the self efficacy group were significantly better than that of the control group(p=.0001). It would be expected that this self efficacy promotion and exercise training program could be applied widely as an effective nursing intervention for kidney transplant recipients.

The Effects of the Self Efficacy Promotion and Exercise Program on the weight, body fat rate, exercise time and cardiopulmonary function of kidney transplant recipients / 성인간호학회지

The purpose of this study is to develop and evaluate the Self Efficacy Promotion and Exercise Program to prevent of obesity and cardiovascular diseases for the kidney transplant recipients. The subjects were selected randomly among the patients who underwent kidney transplantations at one major transplantation hospital in Seoul, Korea. This study ws carried out between November 23, 1999 and February 15, 2000. The subjects in this study consisted of 16 patients who had kidney transplantations between 1 month and 12 months ago prior to this study. They were all on steroids therapy and did not take any physical exercise regularly. The subjects received the self efficacy promotion and exercise program for 12 weeks which contained self efficacy promotion education and exercise program. The weight, body fat rate, exercise time and cardiopulmonary function were evaluated before the experiment and after the experiment. The results were as follows: 1. After the experiment, the weight was significantly decreased than that of before the experiment(p=.0001). 2. After the experiment, the body fat rate was significantly decreased than that of before the experiment(p=.0010). 3. After the experiment, the exercise time was significantly increased than that of before the experiment(p=.0002). 4. After the experiment, the absolute VO2 was significantly increased than that of before the experiment(p=.0008). 5. After the experiment, the relative VO2 was significantly increased than that of before the experiment(p=.0002). This study showed that the self efficacy promotion and exercise program was effective. So it would be expected that this self efficacy promotion and exercise program could be applied as an effective independent nursing intervention widely in prevention of obesity and cardiovascular diseases for kidney transplant recipients.

A Study on the Educational Needs of the Kidney Transplant Patients and Educational Importance perceived by Their Nurses / 성인간호학회지

The purpose of this study was to explore the educational needs of kidney transplant patients and educational importance perceived by their nurses to develop a rehabilitational and educational program. Data were collected from January 29, 1999 to July 30, 1999 with interviews using a structured questionnaire. The subjects for this study were 173, of whom 107 were patients who had had a kidney transplant and had visited the out-patient department and 66 were transplant ward nurses who were taking care of the kidney transplant patients at six general hospitals located in Seoul. The questionnaire used for this study was developed by the investigator through a literature review and collected and modified by 11 professional personnel and 3 kidney transplant patients. The data were analyzed using the SAS program for numbers, percentiles, mean, standard deviation, t-test, ANOVA, and Scheff test. The results were as follows; 1) In the patient group, the total mean score for educational needs was 154.61 and the item mean score was 3.96. In the nurses group, the total mean score for perceived educational importance was 166.26 and the item mean score was 4.26. In the nurses group, perceived educational needs were scored higher than by the patient group. With regard to domains, both patient and nurses group had the highest educational needs and perceived educational importance in the domain of physical condition and the top five items in the educational needs and perceived educational importance were also in the domain of physical condition. 2) In the patient group, women and the divorce/bereavement group had higher educational needs in the domain of nutritional management, those who had been admitted longer than 4 weeks from their kidney transplant time had higher educational needs in the domains of physical condition and those who were less than 4 years from their transplant had higher educational needs in the domain of follow-up care. In the nurses group, those who were married had higher perceived educational importance in the domain of physical condition.
