PURPOSE:Insuline-like growth factor I(IGF-I) is polypeptide mitogen and mediate growth effect of growth hormone(GH). It's serum level is regulated by GH. The aim of this study is to evaluate whether -2 standard deviation of IGF-I level in normal short stature after insuline and L-dopa stimulation test has any diagnostic significance in GH deficiency. METHOD:We included 64 children with GH deficiency(complete GH deiciency 18 cases, partial GH deficiency 46 cases). Their height was below 10 percentile of korean children's standard growth chart. Control group was 175 children whose test results were normal after insuline and L-dopa stimulation test. Serum growth hormone level was measured by IRMA(immunoradiometric assay) with "Daiichi" kit(Japan) and serum IGF-I level was measured with 125I RIA kit (U.S.A). RESULTS: 1)Serum IGF-I level in normal stimulation test result group was increased with the age and the level was higher in female than that of male. 2)Using the cut-off value of -2SD of IGF-I level in control group, sensitivity was 17.2%, specificity was 98.86%, positive predictive value was 84.62%, negative predictive value was 76.55%, and test accuracy was 76.99%. Sensitivity and test accuracy was 44.44% and 93.26% in th complete GH deficiency, respectively. 3)Serum IGF-I level was significantly correlated with peak GH level with insuline stimulation test in control and GH deficiency group(Y=0.018889X+11.32 r= 0.23930 P=0.0014, Y=0.008592X+4.189 r=0.28141 P=0.0267). But serum IGF-I level was was not correlated with peak GH level with L-dopa stimulation test(Y= 0.005609X+13.88 r=0.06625 P=0.3823, Y=0.008293X+2.98 r=0.20895 P=0.1031). CONCLUSION: Serum IGF-I level in GH deficiency group was lower than that of control group and had wide variation of normal range. Based upon above results IGF-I level has limited clinical value in the diagnosis of GH deficiency.

PURPOSE: Hepatitis B virus(HBV) with various mutations has been reported. The aims of this study were to investigate the frequency and manifestation of HBV pre-S/S mutations in children with chronic hepatitis B infection. METHODS: Sera from 17 children with chronic hepatitis B infection were analyzed by direct sequencing of polymerase chain reaction amplification of HBV DNA. Results: Seventeen cases of adr type were analyzed. The deletions in HBV pre-S region were observed in 3(17.6%) of 17 cases. Of 3 deleted cases, 2 had an in-phase deletion in the pre-S1 region spanning 18 bp. Another case had a 18 bp and 3 bp deletions in the pre-S1 region. Many point mutations in HBV pre-S region were detected in all cases and these mutations were observed more frequently in the pre-S2 region than the pre-S1 region. Six point mutations in the pre-S1 region were observed. Eight point mutations in pre-S2 region were observed. Point mutations in the S region were detected in 14(82.4%) of 17 cases. Among these, mutations of the "a" determinant were detected in 4(23.5%) of 17 cases. Mutations at codon 130 and at codon 146 were noted in 2 cases. Combined mutations at codon 124, 126, 146 and at 130, 131, 136, 146 were noted in the other 2 cases. Mutations except "a" determinant region included at codon 3, 29, 73, 120, 184, 214, 226, 227. CONCLUSION: These observations suggest that deletion and point mutations in HBV pre-S1, pre- S2 regions and point mutations in HBV S region are frequent in the children with chronic hepatitis B infection.

PURPOSE: Osteoporosis and growth failure have been known one of the serious side effects of corticosteroid therapy especially in children. This study was designed to evaluate the effect of long-term administration of steroids on bone mineral density(BMD) in children with nephrotic syndrome and its relationship to cumulative steroid dose, the duration of therapy and sex. Meathods : The BMD of the spine and arm were measured by dual energy x-ray absorptiometry in 24 children with biopsy-proven minimal change nephrotic syndrome who have been revealed steroid dependent and/or frequent relapse in its clinical course and in age- and sex-matched healthy controls. The mean duration of steroid therapy was 37+/-29.8 months and the mean cumulative steroid doses was 12.8+/-7.7g/m2. RESULTS: 1) The BMD at arm was 0.57+/-0.06g/cm2 in patient group and 0.59+/- 0.06g/cm2 in control group. The BMD at spine was 0.68+/-0.1g/cm2 in patient group and 0.76+/-0.1g/ cm2 in control group. Compared with control group significant decrease in BMD was detected in patient group at arm(p=0.011) and spine(p<0.01). The bone loss at spine and arm was -10.6+/-7.44% and -3.7+/-5.5%, respectively. The bone loss was more prominant at spine(p<0.01). 2) Bone loss at arm was significantly correlated to the total cumulative dose of steroid(Y=-0.0029-0.294X, r=-0.4148, p=0.0434), but was not correlated to the duration of steroid(Y=-2.15-0.04X, r=0.1396, p=0.4619). At spine, there were no significant correlation between bone loss and the cumulative steroid doses(Y=-8.47-0.178X, r=-0.19397, p=0.363) and the duration of steroid therapy (Y=-9.75-0.025X, r=0.09081, p=0.6332). CONCLUSIONS: The long-term use of steroid can induce significant bone loss at the both site of arm and spine. To minimize the extent of corticosteroid-induced bone loss, BMD measurement using dual energy x-ray absorptiometry in children with nephrotic syndrome would be helpful.

Children aged 3~5 years old represent the challenge in pulmonary function assessment, since evaluating lung function in preschool age group is important for the appropriate treatment for patient with chronic and recurrent cough and wheeze during this period. The joint American Thoracic Society/European Respiratory Society task force has produced recommendations for the spirometric lung function test currently used in the preschool age group. The reliable scientific evidence, documented references and reviews by the experts were used as a support. Reference data of spirometry lung function in preschool children were available in several countries including USA, Norway, Czech, Israel, Canada, and Taiwan. Spirometric pulmonary function tests are feasible in 3~ to 5~year~old children. However, the existing data are not sufficient to make definitive recommendations. Recommendations will need to be revised periodically until sufficient evidence has been collected to make definitive guidelines in various situations.

Cranial nerve palsies are relatively common after trauma, but trochlear nerve palsy is relatively uncommon. Although traumatic trochlear nerve palsy is easy to diagnose clinically because of extraocular movement disturbances, radiologic evaluations of this condition are difficult to perform because of the nerve's small size. Here, we report the case of a patient with delayed traumatic trochlear nerve palsy associated with a traumatic subarachnoid hemorrhage (SAH) and the related radiological findings, as obtained with high-resolution three-dimensional (3D) magnetic resonance imaging (MRI). A 63-year-old woman was brought to the emergency room after a minor head trauma. Neurologic examinations did not reveal any focal neurologic deficits. Brain computed tomography showed a traumatic SAH at the left ambient cistern. The patient complained of vertical diplopia at 3 days post-trauma. Ophthalmologic evaluations revealed trochlear nerve palsy on the left side. High-resolution 3D MRI, performed 20 days post-trauma, revealed continuity of the trochlear nerve and its abutted course by the posterior cerebral artery branch at the brain stem. Chemical irritation due to the SAH and the abutting nerve course were considered causative factors. The trochlear nerve palsy completely resolved during follow-up. This case shows the usefulness of high-resolution 3D MRI for evaluating trochlear nerve palsy.

Carpal tunnel syndrome(CTS), the most common compressive neuropathy, is usually diagnosed by clinical features and nerve conduction test(NCS). However, NCS might show no abnormal finding. Ultrasonography(USG), known as helpful adjunctive in diagnosis of CTS, also might show false negative finding. A 33-year-old woman presented with complaints of pain and numbness in median nerve area on her right hand for 4 years. Despite typical clinical features of CTS, neither NCS nor USG showed abnormal finding. Because of persistent symptom, without significant improvement on conservative management, endoscopic carpal tunnel release(ECTR) was performed with carpal tunnel pressure(CTP) measurement. The measured CTP was 27.9mmHg before ECRT, which was reduced to 5.9mmHg after operation. The pain and numbness subsided after operation. Our case showed the usefulness of CTP measurement in diagnosis of CTS. The measurement of CTP might be an important diagnosis modality for some patients having CTS, especially in cases without definitive findings in NCS and USG.

The effectiveness of dedication video tapes in teaching fundamental nursing skills was investigated using experimental research methodology. Data was collected from 153 students attending fundamental nursing practice classes of two junior colleges and two universities. The subjects were randomly assigned to two groups, one was an experimental group of 74 subjects and the other was a control group of 79 subjects. The in dependent variable was learning type and the dependent variables were the degree of knowledge achievement and nursing skills achievement regarding medication. The research hypotheses of this study were as follows : 1) There will be a significant difference between the experimental group and the control group in the degree of knowledge achievement about medication. 2) There will be a significant difference between the experimental group and the control group in the nursing skills achievement about medication. The data was analyzed with the SPSSWIN program and the t-test, number of subjects and percentiles were then examined. The findings of this study are as follows : 1) There was a significant difference between the experimental group and the control group in the knowledge achievement about medication using P<.05. 2) There was no significant difference between the experimental group and the control group in the nursing skill achievement about medication using P<.05. 3) This study suggests that medication video tapes in the education of fundamental nursing skills are effective for knowledge achievement. As a result, medication video tapes can be effectively utilized for the education of nursing skills regarding medication.

PURPOSE: This study was to analyze the trends and content of all the research (171 research papers) published in the Journal of Fundamentals of Nursing from 1994, when it began to 2000 using an objective tool developed by the researches, and to identify the direction for the future research in Fundamentals of Nursing. METHOD: Research published in the Journal of Fundamentals of Nursing from 1994 were reviewed. RESULT: Most of research (94.2%) was non-degree based and funded research was very limited. The average number of researchers per research study was 2.2 and collaborative research has been gradually increasing. The total number of key words was 331 and the average was 2.6 per research. The major key words were not different from other nursing departments and included home care nursing (10 times), health promotion (8 times), self-care (7 times), self-efficacy (7 times), and hemo-dialysis (6 times). Eighty seven percent of the research was quantitative research, and there were very few qualitative studies. Considering theory level, it was found that 40% were factor related research. For study design, non-experimental studies were most frequent (66%), and the rate, especially of surveys, has remarkably decreased. Selection of subjects by convenience sampling, was most frequent and there were very few studies that provided the rationale for the calculation of sample size. The major subjects of study were patients (44.8%) with various diagnoses. The subjects usually gave oral consent to take part in that study. Giving information (46.9%) and exercise (26.5%) were common nursing interventions, and physiological indices (16.5%), vital signs (10.3%), physical functioning (8.2%), level of knowledge/skill (7.2%) and level of activity (6.2%) were frequently measured as outcome. Variables questionnaires were the major approach used to collect data, and 57.8% of the research provided the Cronbach alpha to guarantee internal consistency of study instruments. Data were analyzed with computerized statistical packages using, ANOVA (42.0%), T test(39.5%), and chi-square test. For the last seven years, nursing research in Fundamentals of Nursing has gradually improved in both quantity and quality. CONCLUSION: It was difficult to find any uniqueness or difference compared to other departments of nursing. In fact, because the history of the Journal of Fundamentals of Nursing is rather short, we can expect that there will be further improvement in quality and content in the future.

OBJECTIVES: To evaluate the Community-Based Participatory Research (CBPR) professional periodontal care program model for patients with hypertension and diabetes. METHODS: This descriptive case study included 151 participants of the professional periodontal care program. The CBPR-based professional periodontal care program consists of 5-steps: ‘Issue identification and prioritization’ (Step 1), ‘Strategy development’ (Step 2), ‘Entry into community’ (Step 3), ‘Implementation’ (Step 4), and ‘Transition’ (Step 5). Quantitative data were analyzed using frequency analysis, and descriptive data with PASW 23.0 (SPSS Inc., Chicago, IL, USA). The results of the Focus group interview (FGI) were classified as ‘general opinions regarding the program planning and operation receptiveness’, ‘sustainability’, ‘potential spread of the program’, and ‘improvement of program’. The interviews were qualitative research involving seven people. RESULTS: 1. Participants increased their interest in health and oral health by managing their hypertension, diabetes, and periodontal disease using community resources. Through this, healthy practices and improved awareness helped to prevent complications and manage periodontal diseases. 2. Community organizations actively cooperated, resulting in positive changes in oral health practices (increased registration of patients in education centers for hypertension and diabetes, and increased number of patients visiting the local dental clinic). In the future, it was positive to participate in the program continuously. CONCLUSIONS: The most important step is ‘Entry into community’, which has led to active participation and cooperation of community organizations and participants. Therefore, community organizations and strategy development should be discussed, and the role of community leaders should be emphasized to build cooperative relationships. In addition, participation in and collaboration with health-based projects should be achieved through a search of various community organizations.

OBJECTIVE: Adequate management of increased intracranial pressure (ICP) is critical in patients with traumatic brain injury (TBI), and decompressive craniectomy is widely used to treat refractory increased ICP. The authors reviewed and analyzed complications following decompressive craniectomy for the management of TBI. METHODS: A total of 89 consecutive patients who underwent decompressive craniectomy for TBI between February 2004 and February 2009 were reviewed retrospectively. Incidence rates of complications secondary to decompressive craniectomy were determined, and analyses were performed to identify clinical factors associated with the development of complications and the poor outcome. RESULTS: Complications secondary to decompressive craniectomy occurred in 48 of the 89 (53.9%) patients. Furthermore, these complications occurred in a sequential fashion at specific times after surgical intervention; cerebral contusion expansion (2.2 +/- 1.2 days), newly appearing subdural or epidural hematoma contralateral to the craniectomy defect (1.5 +/- 0.9 days), epilepsy (2.7 +/- 1.5 days), cerebrospinal fluid leakage through the scalp incision (7.0 +/- 4.2 days), and external cerebral herniation (5.5 +/- 3.3 days). Subdural effusion (10.8 +/- 5.2 days) and postoperative infection (9.8 +/- 3.1 days) developed between one and four weeks postoperatively. Trephined and post-traumatic hydrocephalus syndromes developed after one month postoperatively (at 79.5 +/- 23.6 and 49.2 +/- 14.1 days, respectively). CONCLUSION: A poor GCS score (< or = 8) and an age of > or = 65 were found to be related to the occurrence of one of the above-mentioned complications. These results should help neurosurgeons anticipate these complications, to adopt management strategies that reduce the risks of complications, and to improve clinical outcomes.
