Purpose: The purpose of this study was to identify the knowledge structure of health information (HI) for chronic obstructive pulmonary disease (COPD). Methods: Keywords or meaningful morphemes from HI presented on five health-related websites (HRWs) of one national HI institute and four hospitals, as well as HI needs among patients presented in nine literature, were reviewed, refined, and analyzed using text network analysis and their co-occurrence matrix was generated. Two networks of 61 and 35 keywords, respectively, were analyzed for degree, closeness, and betweenness centrality, as well as betweenness community analysis. Results: The most common keywords pertaining to HI on HRWs were lung, inhaler, smoking, dyspnea, and infection, focusing COPD treatment. In contrast, HI needs among patients were lung, medication, support, symptom, and smoking cessation, expanding to disease management. Two common sub-topic groups in HI on HRWs were COPD overview and medication administration, whereas three common sub-topic groups in HI needs among patients in the literature were COPD overview, self-management, and emotional management. Conclusion The knowledge structure of HI on HRWs is medically oriented, while patients need supportive information. Thus, the support system for self-management and emotional management on HRWs must be informed according to the structure of patients’ needs for HI. Healthcare providers should consider presenting COPD patient-centered information on HRWs.

We report a case of primary adenocarcinoma of the urethra in 62 years old female. Primary carcinoma of the female urethra is an uncommon malignancy that accounts for less than 0.02 per cent of all cancers occurring in women. Adenocarcinoma is rare in the literature. Whereas squamous cell carcinoma and transitional cell carcinoma, which comprise the majority of urethral malignancies, arise form the squamous or epithelial cells lining the urethra, adenocarcinoma arises form the periurethral glands.

Cellular oncogenes are expressed as an intrinsic part of the transformed or neoplastic phenotype. More than 60 of the known cellular oncogenes play a specific role in normal cellular development and differentiation. To examine the correlation between ras oncogene expression and the development of cervical cancer, this study investigated the reactivity of cervical intraepithelial neoplasia(CIN) and carcinoma of the uterine cervix by using anti-ras P21 mouse monoclonal antibody. The expression of ras oncogene significantly increased with the grade of malignancy from 11% in severe dysplasia, 30% in carcinoma in situ, 43% in microinvasive carcinoma, to 53% in invasive cancer. The expression of ras oncogene was not correlated with histologic type, tumor size, and nodal status of cervical cancer. It was concluded that expression of ras oncogene is related to early phase of carcinogenesis and tumor invasion of carcinoma of the uterine cervix.

PURPOSE: To compare results between in femtosecond laser and microkeratome LASIK correction of myopia METHODS: We retrospectively analyzed the result of 94 eyes of 47 patients in the femtosecond group (F) and 103 eyes of 52 patients in the microkeratome group (M). All patients had undergone LASIK using either a femtosecond laser or a microkeratome for making of flap. Patients were divided into groups I (6D< or =) and II (> or =6D) according to preoperative myopia. Each patient was followed up for over 6 months with measurements of uncorrected visual acuity and manifest refraction at 1 week and 1, 3, and 6 months after operation. Complications during and after the operation were reviewed retrospectively in two groups 6month after the operation. RESULTS: In groups F-I, F-II, M-I, and M-II, postoperative 6-month uncorrected visual acuity was 0.98+/-0.08, 0.96+/-0.09, 0.97+/-0.03, 0.98+/-0.09. At the 6-month follow-up, there were no significant differences between the two groups in uncorrected visual acuity and mean spherical equivalent. Corneal opacity was found in 3 eyes in group M and complication related with flap was found 1 eye in group F and 4 eyes in group M. CONCLUSIONS: During a 6-month follow up, LASIK using either a femtosecond laser or a microkeratome has an similar effect in uncorrected visual acuity and mean spherical equivalent. Thus LASIK for using femtosecond laser can be used as an alternative procedure to correct myopia.

Fetal bilateral renal agenesis is a lethal congenital anomaly. An early and reliable prenatal diagnosis is extremely important as it may offer options for pregnancy termination as early as possible. The criteria for the ultrasonographic diagnosis of bilateral renal agenesis are severe oligohydramnios, nonvisualization of the bladder, and the empty renal fossa. However, severe oligohydramnios makes it difficult to diagnose the disease because of poor sonographic resolution. We present two cases of bilateral renal agenesis, one is diagnosed by ultrasonography after amnioinfusion at 24 weeks gestation, the other is diagnosed postnatally after term delivery.

Purpose: This study aimed to identify the factors associated with chemotherapy-induced neutropenia (CIN) in diffuse large B-cell lymphoma (DLBCL) patients undergoing combination chemotherapy. Methods: A total of 111 patients with DLBCL participated in this study at C University Hospital. The CIN group consisted of patients with an absolute neutrophil count (ANC) lower than 1,000 cells/μL. Clinical factors, the level of depression, and the level of healthy lifestyle were measured on the chemotherapy administration day, and the ANC was measured on the next follow-up day. Results: Binary logistic regression analysis showed that the factors associated with CIN in DLBCL were the presence of B symptoms at diagnosis (β=4.69) and low-risk CIN regimen (β=0.10) among clinical factors, and the level of healthy lifestyle (β=0.17). Conclusion Oncology nurses have to focus on the patients vulnerable to CIN having B symptoms at diagnosis, receiving a low-risk CIN regimen, and showing non-adherence to healthy lifestyle practice. Administration of granulocyte colony-stimulating factor can be considered for the patients receiving low-risk CIN regimen to reduce CIN. Education programs including healthy lifestyle practice to improve the immune system should be applied to the DLBCL patients.

BACKGROUND: Liver transplantation (LT) is a complicated procedure with a high incidence of postoperative acute kidney injury (AKI). Previous studies indicate that even transient or mild post-LT AKI can result in critical conditions, including prolonged stays in hospitals and intensive care units and increased morbidity and mortality. The aim of this study was to investigate the association between body mass index (BMI) and occurrence of AKI in LT recipients. METHODS: Medical data from 203 patients who received LT surgery from January 2010 to August 2016 in a single university hospital setting were retrospectively collected and analyzed. Patients were classified as either underweight (BMI <20 kg/m²) or normal weight (20 ≤ BMI < 30 kg/m²). Demographic data, anesthetic methods, complications, and perioperative laboratory test values of each patient were assessed. Propensity analyses and logistic regression were performed to evaluate the association between BMI and post-LT AKI. RESULTS: There was no significant difference in occurrence of post-LT AKI between underweight and normal weight patients. The underweight patient group had significantly longer hospital stay compared with the normal weight patient group (P = 0.023). CONCLUSIONS: BMI classification was neither a positive nor negative predictor of postoperative AKI occurrence. However, patients with lower BMI had significantly longer hospital stay compared with their counterparts. Although our study was limited by its retrospective design, our observations suggest that lower BMI might play a role in post-LT AKI.

PURPOSE: Congenital diaphragmatic hernia is an uncommon cause of respiratory distress in newborn infants and initially characterized by severe restrictive lung dysfunction. The problems of initial management and short-term prognosis have been well reported. However, long-term outcome has not been clearly defined. We studied the late respiratory problems and lung function after repair of congenital diaphragmatic hernia. METHODS: Fourteen patients who had repaired congenital diaphragmatic hernia at Ajou University from January 1995 to August 2009 were included for this study. RESULTS: Six cases (42.8%) showed late respiratory problems including recurrent bronchiolitis, pneumonia, bronchial asthma and prolonged chest wall retraction. Lung perfusion scan showed a perfusion defect in 1 case whose mean perfusion to the operated side was lower than the unaffected lung. Pulmonary function test showed restrictive pulmonary insufficiency in 2 cases. The cases with the late pulmonary problems revealed more restrictive pulmonary insufficiency compared to those without. The prolonged time taken to surgery from diagnosis, prolonged intensive care time, and prolonged ventilator care after surgery have been found to be the determinants of the impaired pulmonary functions. CONCLUSION: In summary, a portion (about 20%) of the patients with congenital diaphragmatic hernia showed impaired pulmonary function, even when they had no apparent respiratory symptom or limitations of activities. From these results, regular long-term follow-up of lung function is required postoperatively in patients with congenital diaphragmatic hernia, especially in cases with the aforementioned risk factors.
