PURPOSE: To find the factors of subjective musculoskeletal symptoms associated with the general characteristics and tasks of operating room nurses (OR nurses) and then to use the factors as basic information for preventing and managing musculoskeletal symptoms in OR nurses. METHOD: This study was an exploratory research. Data were collected using a self-report questionnaire from OR nurses working at 8 polyclinics in Korea during the period from July 26 2004 to August 19 2004. The questionnaire contains 7 questions on general characteristics and 18 questions on tasks in the operating room. RESULT: 187 (75.1%) nurses said they 'had' subjective musculoskeletal symptoms. Statistically significant differences were observed according to clinical career, career as an OR nurse, skillfulness, satisfaction with tasks in the operating room, perception on suitable treatment, care of symptoms by the hospital. weight of hospital linen and weight of a basic operation set (p<.05). CONCLUSION: Musculoskeletal symptoms complained of by OR nurses were significant. This may cause difficulties in nursing tasks in the operating room. Thus, various arrangements should be made for OR nurse with subjective musculoskeletal symptoms at the early stage.

To investigate what heterogeneity exists in breast cancer, 228 consecutive patients with operable invasive duetal carcinoma (IDC), not otherwise specified, were categorized on the basis of the horizontal progression model of carcinogenesis. Using the reversed Black's nuclear grade (RBNG) in the IDC component and the association of ductal carcinoma in situ (DCIS), the patients were classified into pure IDC (IDC de novo or ab initio) as Group I, non-high grade (RBNG 1 and 2) IDC with DCIS as Group II, and high grade (RBNG 3) IDC with DCIS as Group III. The Groups classified in the present study appeared as a prognostic factor independent of known prognostic and predictive factors in multivariate test. Group I had the worst prognosis among the three groups and was the most non-responsive to tamoxifen. After performing stratifying analyses by group, it was found that metastasis-free survival was statistically associated with the status of hormone receptors estrogen receptor and progesterone receptor and tamoxifen therapy only in Group II. In addition, the status of c-erbB-2 expression had prognostic significance only within the Group III. Our results may be used to frame an alternative hypothetical model for breast cancer evolution and will lead us to reconsider the tailoring of the comprehensive therapeutic modality used at the present time.

The infestation caused by itch mite, Sarcoptes scabiei brings about very severe itching aggravated at night, and has a very high transmissibility. The lesions are commonly found on lower abdomen, thigh, axilla, interdigital area, buttocks, and genitalia. But it is rare to find the mite on eye lid. We have experienced a 33 year-old female patient who complained of persistent itching and foreign body sense in upper eyelid, and found a mite there. Then it was removed mechaincally, and the symptoms disappeared without any particular treatment. So we report a case of eye lid infestation by S.scabiei with the review of literatures.

BACKGROUND: Recently elderly people have increased in Korea and increased demands of medical service. This study was carried out to identify diseases and health service utilization patterns of geriatric inpatients to provide better understanding and basis planning to meet the needs of expanding geriatric population. METHOD: We use data of `Patient Survey in Korea` in 1999 and analyzed characteristics of disease structure and utilization patterns of health care service of 54,013 cases of discharged patients aged 65 years or more. RESULT: The proportion of the elderly in total discharged patients is 14.7%. Male to female ratio is 1:1.3 and most common age group was between 65 and 69 years old. 84.2% of elderly patients were admitted at secondary or tertiary health care facilities. The most common disease in geriatric inpatients is malig- nancy in male and vascular disease in female. The average duration of hospitalization is 14.2 days. They stay longer than the nation wide average hospital length and stay longest when they are admitted by mental and behavioral disorders. CONCLUSION: Geriatric patients are admitted mostly with chronic degenerative diseases such as neoplasm and vascular disease. Elders prefer to be admitted to tertiary hospitals and oriental hospitals. They stay more in hospital.

To investigate the drug effect of topical Mitomycin C in various concentrations combined with steroid, we used 30 rabbits whose corneal epitheliums were abraded intentionally. They were divided into 5 groups. Using MMC in various concentrations and steroids, we instilled them into right eyes and saline into left eyes as control. We measured the healing rate at a interval of 12 hours. Three months later, we sacrificed one of them and examined the pathological changes from various ocular tissues. We found many complications such as corneal edema, ulcer, opacity and definite delay of wound healing when the concentration higher than 0.04%MMC was used. There were also decreased fibroblast cells in H-E staining. The steroids seemed not to pose any influence on the effect of MMC. In conclusion, we must take the great care in the use of MMC, and the concentration should be low when used. In addition, we still think there ought to be more studies as to the effect of steroids according to MMC levels.

Although nitric oxide (NO) plays an important role in the pathophysiological process of cerebral ischemia or severe traumatic brain injury, its contribution to the pathogenesis of moderate diffuse axonal injury (mDAI) remains to be clarified. The alterations in nitric oxide synthase (NOS) activity and the histopathological response after mDAI was investigated. Forty anesthetized Sprague-Dawley adult rats were injured with a Marmarou's weight-drop device through a Plexiglas guide tube. These rats were divided into 8 groups (control, 1 hr, 2 hr, 3 hr, 6 hr, 12 hr, 24 hr, 48 hr after trauma). The temporal pattern of apoptosis in the adult rat brain after mDAI was characterized using TUNEL histochemistry. In addition, the cDNA for NOS activity was amplified using RT-PCR. The PCR products were electrophoresed on a 2% agarose gel. eNOS activity was not detected, but nNOS activity was expressed after 3 hr and continuously 48 hr after impact, which was approximately double that of the control group at 12 and 24 hr. Subsequently, there was a decrease in activity after 48 hr. The iNOS activity increased dramatically after 12 hr and was constant for a further 12 hr followed by a dramatic decrease below the level of the control group. Significant apoptotic changes occurred 12 and 24 hr. after insult. nNOS and iNOS activity were affected after moderate diffuse axonal injury in a time-dependent manner and there was a close relation between the apoptotic changes and NOS activity. Although the nNOS activity was expressed early, its activity was not stronger th an iNOS, which was expressed later.

PURPOSE: The aim of this study was to describe the surgical clip-related complications that can occur after open retropubic prostatectomy (RRP), pure laparoscopic prostatectomy (LRP), and robot-assisted laparoscopic radical prostatectomy (RALP). MATERIALS AND METHODS: A database of 641 patients who underwent RRP (n=439), LRP (n=49), and RALP (n=153) at our institution between January 2006 and April 2009 was reviewed to identify patients with complications related to the use of surgical clips. The median follow-up time for the entire cohort was 19.0 months (range, 1-42 months). RESULTS: Of the 641 patients, 25 (5.7%), 1 (2.0%), and 2 (1.3%) had a bladder neck contracture after RRP, LRP, and RALP, respectively. Two RRP patients had a bladder stone. In total, 6 patients had surgical clip-related complications. Metal clip migration was associated with 2 (8%) of the 25 RRP cases of bladder neck contracture and both (100%) of the RRP cases of bladder stone. Moreover, both (100%) of the RALP cases of bladder neck contractures were associated with Hem-o-lok clip migration into the anastomotic site. CONCLUSIONS: Surgical clips are prone to migration and may cause, or significantly contribute to, bladder neck contracture or the formation of bladder stones after radical prostatectomy. These findings also suggest that because the incidence of bladder neck contracture after RALP is low, the migration of Hem-o-lok clips should be suspected when voiding difficulty occurs after RALP.

PURPOSE: The study is designed to develop an educational CD-Program for prevention and control of obesity among primary school students. METHOD: The study is conducted from June 15, 2000 to April 15, 2002. Based on the course of program development suggested by Dick and Cray (1990), the study followed the planning, development, education and evaluation of a program. RESULT: The developed CD-Program consists 2 parts each for lower and higher grades of primary school students. The introduction part of the first trial for lower grade students uses quiz to encourage their motivations, the body proceeds with motion pictures and animations to trigger their interests. The introduction part of the second trial for the lower grades consists of remembering the exhibition lecture. The first trial for higher grades of primary school students builds on the contents of the low grades. Its body part, how to determine obesity and calculate ones own obesity, puts ones own weight and height in by the mouse. For the second trial of the higher grades, the body consists of life-style, diet, and regiments. CONCLUSION: The merits of this CD-Program are that to be possible an interaction between teachers and students.
