PURPOSE: This study was done to evaluate the effect and retention of CPR training in nursing students. METHODS: The participants were 64 nursing students enrolled in K University in Busan. Data were collected from April 3 to October 20, 2006 using a structured questionnaire. Data were analyzed using the SPSS/PC 12.0 statistical program. RESULTS: The first hypothesis, that knowledge (t=-17.865, p=0.000) and skill (t=-11.216, p= 0.000) scored directly following the teaching program would be higher than before the program, was supported. The second hypothesis, that knowledge (t=-8.325, p=0.171) and skill (t=-9.812, p=0.062) scored directly after the teaching program would be higher than two months later, was rejected. The third hypothesis, that knowledge (t=-9.162, p=0.010) and skill (t=-6.019, p=0.023) scored two months after the program would be higher than four months after the program, was supported. The last hypothesis, that knowledge (t=9.169, p=0.210) and skill (t=-5.012, p=0.319) scored four months after the program would be higher than six months after the program, was rejected. CONCLUSION: Overall retention of CPR training among nursing students, without reinforcement, decreases most significantly between two and four months following initial training. Accordingly CPR training should be repeated with the same clients every four months.

The hemostatic effect of endoscopic microwave coagulation method for upper gastrointestinal bleeding was evaluated clinically. Hemostasis over 72 hours was achieved in 18 of 20 cases (90%) with upper gastrointestinal bleeding by the endoscopic microwave coagulation method. It is noteworthy that this method was effective in all 4 cases of pulsatile bleeding from exposed vessels. We conclude that this method is useful for emergency endoscopic hemostasis on upper gastrointestinal bleeding, especially bleeding from exposed vessels.

With the increase of frequency and the recent development of surgical treatment in brachial plexus injury, the requirement for accurate assessment between supra and infraganglionic injury is increased. Cervical myelography has been the popular tool in evaluating the root lesion since the first introduction of Murphey et al. in 1947. However, the invasiveness of procedure has been the impediment to the common-use. But with the utilization of water-soluble contrast media, Metrizamide, such impediment can be alleviated. Author has performed myelography in 27 patients along with surgical exploration in 18 patients since 1984. And the results were as follows. 1. 85% of 27 patient revealed anomaly of root in myelography. 2. Traumatic menimgoceles were typical findings and most of them were located at C7 and C5. 3. Myelography reaveled 70%(28 root) of anomalies among 40 root lesions, confirmed by surgical explorations. 4. Myelography is considered to be very effective in evaluating supra and infraganglionic root lesions when its results is correlated with physical and other neurological examination.

The classification of thoracolumbar spinal injuries has been based on morphological criteria, mechanism or both. Recently Denis and Macfee insisted no the middle column of the spine but their classification is useful as a morphologic description. Especially, the classification and decision of treatment are difficult in the burst fracture. So we have applied the new classification described by Gertzbein that considers the morphologic patterns and mechanism of injury and compared with another classifications. We studied 28 cases of the thoracolumbar burst fracture who were treated and followed up at Wonkwang university hospital from May, 1988 to March, 1992. We classified burst fracture according to the three kind of classifications and CT finding. 1. The burst fracture associated with flexion-distraction injury was revealed 5 cases(about 18%). 2. In the treatment, Type A injuries requires the use of distractive and type B requires compressive forces in the correcting the deformity.

Carcinomatous degeneration of chronic scars, known as Marjcinulcer, are relatively rare. The majority of them are quamous cell carcinoma or other skin cancers including basal cell carcinoma. But malignant melanone, especially amelanotic melanoma oveloping from a chronic burn scar is extremely rare. We have experiencedl a case of amelanotic melanoma arising ron a chronic burn scar in a patient, 53 year-old female, who had a painful erythematous ulcra edonodule on the left heel for about 20 years since she had sustained a burn there at the age of 1 year. Although there are no melanin pigments in hematoxylinsin(H & E) stain as well a Fontana Masson stain, a biopsy specimen from the skin lesion revealed cytologic atypia and junctional activity in the dermoepidermal junction arcl positive immunohistochemical staier, for S-100 protein, which is consistent with amelanotic melanoma. lesion was widely excised and a skin graft was dure She was also treated with intralesional BCG injection and recurrence or metastasis was ot detected during the follow up period of 6 months.

Clean intermittent catheterization(CIC) is known as a safe, acceptable method in patient with neurogenic bladder due to spinal cord injury. We studied retrospectively the long term results of CIC in spinal cord injury patients. A total of 34 patients(12 upper. motor neuron lesion and 22 lower motor neuron lesion) was followed for 7 months to 82 months (average followup 31.5 months). Sixteen of 34 patient with high intravesical pressure improved after CIC. Two of 3 with abnormal BUN/Cr level, 13 of 14 with hydronephrosis, and all 12 with vesicoureteral reflux improved after CIC. But one patient with abnormal BUN/Cr was worsen. Before CIC period symptomatic bacteriuria developed in 29 patients, epididymitis in 8 patients and bladder stone in 3 patients. But after CIC, each of them was changed to 15, 1 and 1. In conclusion, We think that CIC is a good method for preservation of renal function and to decrease the urologic complications. But patients should be well motivated, cooperative and able to use their hands for continuous CIC.

PURPOSE: This study aimed to evaluate the cancer detection rate in a Korean population with prostate-specific antigen (PSA) levels greater than or equal to 20.0ng/mL. MATERIALS AND METHODS: A total of 174 men 50 to 79 years old (median 69) included in the study. The median prostate volume of the patients was 44.8mL (range 14.1 to 210.0) and their serum PSA ranged from 20.0 to 9725.0ng/mL (median 44.8). RESULTS: Of 174 men 141 (81.0%) were diagnosed with prostate cancer on initial biopsy. In the total number of patients, the positive predictive value (PPV) was 62.9% for PSA 20 to 29.9, 72.7% for PSA 30 to 39.9 and 100% for PSA 40 to 49.9 ng/mL. In patients with an abnormal digital rectal examination (DRE), the values for these PSA ranges increased to 89.5%, 91.7% and 100%, respectively. The PPV was 81.0% for PSA cutoff of 20, 89.2% for a cutoff of 30, 95.4% for a cutoff of 40, and 94.7% for a cutoff of 50 ng/mL. In conjunction with an abnormal DRE, the values for these PSA cutoffs increased to 95.9%, 98.1%, 100%, and 100%, respectively. CONCLUSION: Our data suggest the ability to predict the presence of prostate cancer reliably on initial biopsy when PSA threshold is greater than or equal to 50ng/mL. This PSA threshold may be lowered to 40ng/mL in the presence of an abnormal DRE. In Korean men with high PSA, the detection rate of prostate cancer on biopsy appears to be comparable to that for American men.

Gastritis cystica polyposa (GCP) is a lesion characterized by all the histological features described for hyperplastic polyps, And there is s marked proliferation of muscular elements and entrapment of numerous epithelial cysts. These lesions have been described at gastroenterostomy stomas, at peptic ulcer edges, and in association with carcinoma. It is rare that GCP presenting as a submucosal tumar-like lesion develops in the absence of above mentioned associated conditions. We had experienced a 69 year-old man with GCP. Barium X-ray and endoacopic findings showed submucosal tumor in antrum, and endoscopic ultrasonograpic findings showed markedly thickened mucosal layer with scattered hypoechoeic areas and the submucosal layer well preserved. GCP was confirmed by histological examination of resected stomach.
