PURPOSE: This study was conducted to identify the factors contributing to sleep disorders in patients on hemodialysis. Methods: A descriptive correlational study design was used. The participants were 135 patients on hemodialysis in hemodialysis clinics. Data were collected from March to May 2007 using structured questionnaires and hematologic sample. Stepwise multiple regression was used to identify factors influencing sleep disorders among the demographic-clinical factors, depression and fatigue. RESULTS: About 69% of the patients had a sleep disorders. There were significant differences in sleep disorders according to marital status, caregiver, religion, economic level, insurance, erythropoietin, somnifacient, and antihypertensive agents. But there were no differences according to age, gender, dialysis period, or antidepressants. Their sleep disorders had significant correlations with depression, and fatigue, and a significant negative correlation with Protein, Albumin, Phosphate and BUN. But there were no correlations with hematocrit, hemoglobin, creatinine, sodium, potassium, or calcium. Depression and fatigue were factors influencing sleep disorders. They accounted for 43.8% of the variance in sleep disorders in these patients. CONCLUSION: Findings provide an understanding of sleep disorders and the factors that are an influence in patients on hemodialysis. To promote sleep in these patients, nursing interventions to manage depression and fatigue are needed.

This study was conducted to develop a web-based instruction program for nurses caring patients with open heart surgery. Actually, the web-based instruction program was developed for the purpose of improving knowledge and problem solving skills among nurses for intensive care units. Also, I hope this program will be used as a tool of continuing education program for nurses and contributed to the building of life-time learning system focused on advanced nursing practice. Based on the Instructional Systems Development(ISD) model and the model of Web-Based Instruction(WBI) developmental process by Chang(1998), this study was conducted from May, 1998 to May, 1999 with the five steps: analysis, design, data collection and reconstruction, programming and publishing, and evaluation steps.

Generally, lateral plating is used for a comminuted fracture of the distal femur. However, in some cases, it has been shown that using a medial plate is necessary to achieve better outcome. Nevertheless, there are no available anatomical plates that fit either the distal medial femoral condyle or fracture fixation, except for the relatively short plate developed for distal femoral osteotomy. We found that locking compression plate-proximal lateral tibia (LCP-PLT) fits anatomically well for the contour of the ipsilateral medial femoral condyle. Moreover, LCP-PLT has less risk of breaking the thread holes since it rarely needs to be bent. We report a plastic bone model study and two cases of distal femoral fractures fixed with medial plating using LCP-PLT.

PURPOSE: Effective literature searching is essential to support evidence-based nursing. The aim of this study was to present our recent systematic search experience to identify guidelines in PubMed for prevention of catheter-associated urinary tract infections. METHODS: Five approaches to the literature search via PubMed were employed. The searches were restricted to items published from 1980 to 2010, for patients admitted to hospital, and in the English language. The search results were compared using the number of records and relevant items, and the sensitivity and precision of each search strategy. RESULTS: The individual approaches retrieved 19-141 of records and 3-6 of relevant items. Sensitivity ranged from 37.5% to 75.0% with the highest values for simple searches and a search combining MeSH terms and free textwords with a methodological search filter. Precision varied from 4.3% to 21.7% and the highest precision was found for MeSH terms with limits feature. CONCLUSION: The simple search in PubMed is an appropriate way for nurses in a busy clinical practice to search the literature for evidence. However, several approaches using MeSH terms, free textwords, limits feature or methodological search filters are also required to have more efficient and better informed search results.

Abductor deficiency in native hip joint may cause severe limping and pain. It is more serious situation in case of arthroplasty due to instability and recurrent dislocation. Well-known causes of abductor deficiency are repeated surgery, chronic trochanteric bursitis, superior gluteal nerve injury, failure of repair of abductor tendon insertion to the greater trochanter. Author had experienced primary abductor deficiency during total hip replacement and treated successfully with the transfer of gluteus maximus. We'd like to introduce the operation technique with the review of literature.

PURPOSE: To find out the effect of early closed reduction and internal fixation (within 24 hours after admission to hospital) on the morbidity and mortality in the elderly with intertrochanteric fractures of the femur. MATERIALS AND METHODS: Retrospectively, we analyzed 99 patients with intertrochanteric fracture of the femur who underwent surgery from January, 2009 to December, 2010. We reviewed 89 of the 99 patients and checked for early complications and reviewed the mortality rates 3 months, 6 months and 1 year after surgery. There were 24 males and 65 females. The average age was 79.8 years (61-99 years). According to the American Society of Anesthesiologists classification, 25 patients were class 1, 37 patients were class 2, 26 patients were class 3, and 1 patient was class 4. All patients were operated on by one surgeon, who was skilled in inserting intramedullary nail. RESULTS: The average surgical time was 43 minutes and the average intraoperative blood loss was 165 ml. Sixteen patients experienced delirium but all of them recovered. One patient had pneumonia at one month after surgery. Pressure sores developed in one patient but improved with conservative treatment. Pulmonary thromboembolism developed in some patients one month after surgery. Three patients (3.4%) died within three months and one patient (1.1%) died between three and six months after surgery, but no patient died between six months and one year after surgery. CONCLUSION: If patients are optimized for the operation, early internal fixation of trochanteric fracture in elderly patients after arrival at the hospital should be considered to reduce early complications and mortality.

Femoroacetabular impingement and dysplatic hip joint is well known cause of osteoarthritis. In these diseases, labral tear and subsequent cartilage damage is thought to be main pathophysiology of development of osteoarthritis. If there are no known bony abnormalities, we called it as idiopathic osteoarthritis. Normal appearance of acetabular labrum is a continuous, usually triangular structure that attaches to the bony rim of the acetabulum and is completed at the inferior portion by the transverse acetabular ligament over the acetabular notch. A few authors reported intra-articular labrum and its relation to the development of osteoarthritis. But they didn't comment the primary bony abnormality especially acetabulum. We'd like to report x-ray, computed tomogram, magnetic resonance arthrogram and arthroscopic findings of a case had double contour sign of acetabular dome combined with intrusion of acetabular labrum.

PURPOSE: We evaluated the short term results after treatment of cam type femoroacetabular impingement (FAI) by arthroscopy. MATERIALS AND METHODS: We evaluated the clinical and radiological results of arthroscopically treated cam type FAI in patients who had failed conservative treatment with hip pain, with at least 12 months follow-up, from November 2010 to December 2012. There were 19 males and six females. Mean age of patients was 32.9 years (19-57 years) and mean follow up period was 17.2 months (13-31 months). We analyzed the alpha angle, head neck offset, visual analogue scale (VAS), and modified Harris hip score (MHHS). RESULTS: Mean alpha angle improved from 64.8degrees to 39.9degrees and mean head neck offset also improved from 0.8 to 7.6 mm. Peripheral longitudinal and radial fibrillated labral tear was the most common in the anterosuperior quadrant. Damage to acetabular cartilage was identified in 14 patients. Mean VAS improved from 6.3 to 0.9 and mean MHHS improved from 51.7 to 73.6. Complications associated with the operation included three cases of femoral head articular cartilage injury, two cases of pudendal nerve injury, and two cases of lateral femoral cutaneous nerve injury. CONCLUSION: Although the short term results for arthroscopically treated cam type FAI were satisfactory, care must be taken to reduce the complications associated with arthroscopy and long term follow is needed in order to determine whether or not it can reduce osteoarthritis of the hip.

PURPOSE: We evaluated the bleeding volume after surgery for trochanteric fractures of the femur in patients treated with antiplatelet agents according to surgical timing. MATERIALS AND METHODS: We selected 20 patients who had trochanteric fractures of the femur treated with antiplatelet agents from January 2009 to June 2010. Group I included 9 patients who discontinued antiplatelet medication and had delayed operations at an average of 6.5 days and Group II included 11 patients who underwent early operations within 24 hours. Group I included 2 males and 7 females; their average age was 77.8 years (range 59~86). Group II included 4 males and 7 females, with an average age of 73.5 years (range 61~84). We compared the two groups' volume of intraoperative bleeding, the preoperative and postoperative hemoglobin levels and the volume of postoperative transfusion. The Mann-Whitney U test was used for statistical analysis. RESULTS: The volume of intraoperative bleeding was 88 ml in group I and 106 ml in group II (p>0.01). The difference in the hemoglobin was a decrease of 2.4 mg% in group I and a decrease of 2.2 mg% in group II (p>0.01). The volume of postoperative transfusion was 0.6 pints in group I and 1 pint in group II (p>0.01). CONCLUSION: We found a similar bleeding volume regardless of operative timing after surgery for trochanteric fractures of the femur in patients treated with antiplatelet agents.

PURPOSE: With the westernization of dietary life, domestic prostate cancer prevalence has remarkably increased recently. Therefore, to examine the effects of obesity on prostate cancer, we analyzed the effects of leptin and adiponectin, which are the cytokines secreted from adipocytes, on prostate cancer in vitro and confirmed the results by in vivo experiment. MATERIALS AND METHODS: In vitro, the human androgen-independent prostate cancer cell line DU-145 was exposed to various concentrations of adiponectin and leptin, and their effects were measured with the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. In vivo, the effects of tumor growth were observed in xenografted nude mice with prostate cancer. RESULTS: Adiponectin significantly repressed DU-145 cell growth in a dose-dependent manner. Leptin promoted DU-145 cell growth in dose-dependent manner, but it was not significant statistically. In vivo, adiponectin-treated mice demonstrated a reduced tumor volume, although it was not significant statistically. By contrast, leptin-treated mice showed a significantly increased tumor volume (p<0.01). CONCLUSIONS: The in vitro and in vivo finding suggested that adiponectin suppresses the proliferation of prostate cancer cells and that leptin plays an important role in the proliferation of prostate cancer cells. We suggest that adiponectin and leptin have a relation to the progression of prostate cancer in the obese population.
