Purpose: This descriptive study investigated the effects of nurses’ knowledge of withdrawalof life-sustaining treatment, death anxiety, and perceptions of hospice care on their attitudes toward withdrawal of life-sustaining treatment. Methods: Data were collected from 262 nurses at tertiary hospitals, general hospitals, or primary hospitals in Busan, Korea, and statistically analyzed using the t-test, analysis of variance, the Scheffé test, Pearson correlation coefficients, and hierarchical regression analysis. Results: The participants’ scores were 3.68±0.45 (out of 5) for attitudes toward withdrawal of life-sustaining treatment, 0.65± 0.15 (out of 1) for knowledge of withdrawal of life-sustaining treatment, 2.61±0.26 (out of 4) for death anxiety, and 4.06±0.43 (out of 5) for perceptions of hospice care. Furthermore, knowledge of withdrawal of life-sustaining treatment and perceptions of hospice care showed positive correlations with attitudes toward withdrawal of life-sustaining treatment, while death anxiety showed a negative correlation. The most significant factors influencing attitudes toward withdrawal of life-sustaining treatment were perceptions of hospice care, followed by having experienced caring for patients who withdrew life-sustaining treatment, death anxiety, having a spouse, and ethical values, and the overall explanatory power was 43.0%. Conclusion This study showed that perceptions of hospice were an important fac-tor influencing nurses’ attitudes toward withdrawal of life-sustaining treatment. Therefore,it is necessary to develop and validate educational intervention programs that can improve perceptions of hospice care.

A review of the literature on cancer pain revealed that many persons with cancer receive inadequate analgesia for pain control, due in part to a lack of knowledge of the control of cancer pain by both physicians and nurses. This study is composed of two parts : one is to train nurses to change their knowledge of and attitude toward the pain management of patients having cancer and to evaluate the effectiveness of this training in comparison with other non-trained group ; the other is to test the applicability of the pain management method knowledge and attitude in the levels of pain of oncology patients. General characteristics of nurses such as age, education, educational experiences of cancer pain management were not different in both groups except the clinical experience. General characteristics of cancer patients and pain-related variables such as pain, sleep, daily activities, treatment modalities, causes of pain were not different in both groups except the educational levels of patients. After an eight-hour educational program given to the experimental nurse group, the knowledge and attitude about assessment of cancer pain, pain medication, and pharmacological knowledge were significantly higher in the experimental group than in the control group, while knowledge about classification of analgesics was not significantly different. The amount of analgesics, measured by the morphine equivalent doses, used in the experimental group was significantly lower than in the control group in the first and the last days. The experimental group used more systematic ways of drug changes from non-narcotic analgesics to narcotic analgesics than the control group. This indicated that the control group used fentanyl patches more commonly than in the control group. Cancer pain scores of both group of patients were measured on an hourly bases for a week in both groups. The patients' pain scores of the first day of measurement in experimental group were not significantly higher than those of control group of patients, while those of the last day were significantly higher than those of the control group. This study supports the need for educational program for the management of cancer pain to the nurses and the doctors.

RNA fingerprinting using on arbitrary primed polymerase chain reaction (RAP-PCR) was carried out to identify differentially expressed genes in HL-60 cell after treatment of methylmethane sulfonate (MMS). Twenty differentially expressed PCR products were cloned and analyzed. We have successfully obtained eight partial cDNA sequences by TA cloning method. Among these, six cDNAs were up-regulated and two cDNAs were down-regulated after the MMS treatment. Of these six up-regulated cDNAs, 3 cDNAs were equivalent to known genes in the GenBank/EMBL databases with 98~100% homology searched by BLAST program: genomic DNA fragment containing CpGg island (clone 26h8), Human Rev interacting protein-1 (RIP-1), and human zinc finger protein-4 (HZF4). The sequences of the three remaining cDNA were entirely new genes, but we didn't try to identify a full cDNA sequence. Two clones called KIAA0060 and KIAA0065, were down-regulated in HL-60 cells after the MMS treatment. These findings suggest that the RNA fingerprinting method using RAP-PCR is an effective method which can identify and separate the differentially expressed cDNAs and that the isolated cDNAs might involve in regulation mechanism of apoptosis and/or cell cycle delay, especially a p53-independent pathway, in the cells after DNA damage. But the nature of cDNAs that we have isolated remains to be elucidated.

PURPOSE: To report the expression of decorin and TGF-beta in partial myotomy of the extraocular muscle in rats. METHODS: Partial myotomy of the superior rectus muscle was performed on the right eye of 10 Sprague-Dawley rats followed by exposure of the left superior rectus muscle and a simple suture of the conjunctiva. The bilateral superior rectus muscle was obtained from all rats at 2 weeks postoperatively. The tissues were observed under light microscopy with hematoxylin-eosin, Masson's trichrome staining and immunohistochemistry. RESULTS: Histological examinations of the surgical area at 2 weeks after postoperatively showed irregularly concentrated fibrosis on light microscopy with hematoxylin-eosin and Masson's trichrome staining of the experimental eyes. Immnohistochemistry showed that expression of decorin was in the same location as TGF-beta in the experimental group. CONCLUSIONS: The expression of decorin was found in the healing process after partial myotomy of the extraocular muscle in rats. Immunohistochemistry showed that expression of decorin was in the same location as with TGF-beta.

Eosinophilic gastroenteritis (EG) is a rare disease characterized by massive eosinophilic infiltration of gastrointestinal tissue, peripheral eosinophilia, and nonspecific gastrointestinal symptoms. The mucosal type of EG commonly presented with malabsorption and anemia. However, the role of food allergy as a stimulus to EG has not yet been clearly defined. A 27-year-old man was referred to the Emergency Department with dyspepsia and leg swelling. The initial laboratory test should as follows: hemoglobin level, 6.4 g/dL; white blood cell count, 7,400/microL with 24.4% of eosinophil fraction; serum total protein, 3.9 g/dL; albumin level, 2.8 g/dL. Gastric endoscopy ruled out gastrointestinal bleeding showed multiple nodular raised lesions on the gastric antrum, which revealed increased eosinophilic infiltration (above 100/high power field). He had experienced nausea whenever eating beef, porks or fish. High serum specific IgE levels to offending foods (beef, 0.82 kU/L; pork, 0.83 kU/L; egg white, 0.40 kU/L; egg yolk, 0.54 kU/L; milk, 0.81 kU/L) were noted. He was instructed strictly to avoid food allergens with oral prednisolone therapy. Approximately 6 months after offending food restriction, the eosinophil count fell down to 400/microL, the hemoglobin level was returned to 11.5 g/dL and the serum albumin level was increased to 4.1 g/dL. We report a case of EG caused by multiple food allergy which leads to malabsorption and iron-deficiency anemia.

PURPOSE: To report the case of a child with triple X syndrome presenting with exotropia and chorioretinal coloboma. CASE SUMMARY: A one-year-old female infant presented with 35PD exotropia in the primary position. The patient had poor fixation of the right eye, and a fundus examination showed chorioretinal coloboma in the inferior region of her right eye. The patient also exhibited syndactyly of the right hand. Brain magnetic resonance imaging revealed a well-defined 2 cm cyst in the right cerebellum. Upon chromosomal study, the patient's karyotype was found to be 47, XXX. CONCLUSIONS: When infants or children present with ophthalmologic findings such as strabismus and coloboma, systemic conditions and congenital problems should be considered.

OBJECTIVE: Methicillin resistant Staphylococcus aureus (MRSA) is the most common cause of postoperative infection in instrumented fusion surgery. Although MRSA is well-known cause of nosocomial infection, emerging evidence supports that there could be MRSA infection from community. This study evaluated the nasal colonization rate of MRSA among healthy adults within the age range of spinal fusion surgery in Korea. METHODS: Nasal swabs were collected from 99 participants who visited health promotion center. A structured questionnaire regarding healthcare-associated MRSA risk factors was collected simultaneously. Staphylococcus aureus was confirmed by latex agglutination. The resistance to methicillin was identified by oxacillin screening test. RESULTS: Of the 99 participants, 12 (12.1%) had S. aureus isolates. The nasal carriage rate of methicillin susceptible S. aureus (MSSA) was 9 (9.1%). MRSA was identified in 3 participants (3.0%). CONCLUSION: Among the age range of possible spinal fusion surgery, nasal colonization study revealed substantial rate of preoperative MRSA carriers even in healthy adults. A postoperative MRSA infection should not be exclusively considered to be due to surgery-related contamination.

The aim of this study was to investigate the relationships between the gadd genes expression and an apoptosis induction in two different growing cell types after treatments with cisplatin and methylmethan sulfonate (MMS). We have examined the kinetics and specificity of gadd45 and gadd153 expression following cisplatin and MMS treatments to HL-60 cells and primary cultured human kidney (HKN) cells. We have also determined an induction time of apoptosis by DNA fragmentation analysis and the presence of the cell cycle arrest by a flow cytometric measurement. The results were as follows. In non-adherent HL-60 cells, a typical ladder pattern was observed within 4 hours after treatments of 20 micrometer of cisplatin and 100 microgram/ml of MMS. At the same time while adherent HKN cells failed to exhibit a ladder pattern at even higher doses of genotoxic agents. Since HL-60 cells do not have p53 gene, these findings suggest the presence of a p53-independent apoptotic pathway. The increasing patterns of the mRNA levels of gadd45 and gadd153 varied with the type of genotoxic agents. In the case of MMS treatment, the induction was rapid and transient, regardless of the cell types. The mRNA level peaked at 4 hours after MMS treatment and markedly decreased after 12 hours. On the other hand, cisplatin-induced transcriptions of gadd45 and gadd153 continued to increase for at least 24 hours and reached a peak level at 48 hours after cisplatin treatment, regardless of the cell types. HL-60 cells revealed G2 arrest following 24 hours after cisplatin and MMS treatments. These findings suggest that the regulation mechanism of apoptosis between adherent and non-adherent cells, might be different and that gadd45 and gadd153 might have an important role in DNA repair rather than apoptosis. Also, the findings suggest that an expression pattern of gadd45 and gadd153 might be different according to the type of genotoxic agents.

BACKGROUND: BATHE, the acronym for background, affect, trouble, handling, and empathy, is an interview approach that can be applied in the out-patient setting whereby questions belonging to each of the 5 categories are asked in the above order. As we have been taught to believe that BATHE raises the level of patient satisfaction and the quality of medical treatment overall, this study was designed to test the validity of the claim that applying BATHE heightens patient satisfaction. METHODS: Each of the 5 doctors was assigned 10 patients (5 in the BATHE group and the other 5 in the control group) with each patient being randomly assigned to either of the groups. The control group was interviewed as usual and the BATHE group was interviewed using BATHE. Immediately after the interview, each patient anonymously filled out a patient satisfaction questionnaire. Whether the questions asked were appropriate for each category of the protocol was evaluated by the researcher through video clips taped during the interviews. RESULTS: On 7 out of 10 items on the patient satisfaction questionnaire, the BATHE group was found to experience higher level of satisfaction than the control group in a statistically significant manner. The questions asked the BATHE group were confirmed to be more appropriate for each category of the protocol except empathy than those asked the control group. CONCLUSION: As applying the BATHE approach was found to achieve higher level of patient satisfaction, we recommend using it in the out-patient setting.

PURPOSE: Hydronephrosis is found about 30% of children with urinary tract infection (UTI). It can be caused by various conditions, although most childhood hydronephrosis is congenital. This study was performed to investigate the relationship between febrile UTI and hydronephrosis. METHODS: We retrospectively reviewed the medical charts of 183 patients diagnosed as UTI between January 2007 and May 2009 at Korea University Guro Hospital. Inclusion criteria were as followings; 1) fever more than 37.5degrees C measured in the axilla , 2) positive urine culture, 3) no history of urinary tract anomaly on antenatal sonography and urinary tract infection. We classified the enrolled children into two groups of patients with hydronephrosis (HN) and those without hydronephrosis (NHN). RESULTS: The 80 patients were HN and 103 patients NHN. Hydronephrosis was found in 58 patients with left kidney, 8 right and 14 both kidneys. Most of hydronephrosis were of low grade. Compared with NHN group, initial renal cortical defects on DMSA scan significantly increased in HN group (HN 37.5%, NHN 16.5%, P < 0.05). The incidence of VUR was not different between the two groups (HN 22%, NHN 12.1%). White blood cell counts and C-reactive protein were not different between the two groups. Follow-up DMSA scan (about 6 months later after UTI) showed no difference of renal scarring in both two groups. CONCLUSION: Our data suggests that hydronephrosis in febrile UTI patients is clinically useful for detecting renal cortical defects, but is not associated with follow-up renal scar.
