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.

PURPOSE: Goggles are frequently worn in the sport of swimming and are designed to form a seal around the periorbital tissue orbit. The resultant pressure on the eye may have the potential to affect intraocular pressure and blood flow of the optic nerve head. This study evaluates the influence of wearing swimming goggles on intraocular pressure (IOP) and blood flow of the ocular nerve head (ONH) in normal subjects. MATERIALS AND METHODS: Thirty healthy participants took part in this study. The IOP of each participant was measured using a Goldmann tonometer. Measurements were taken immediately before putting on swimming goggles, at 5, 10, 30, and 60 minutes after putting on swimming goggles, and then immediately after taking off the goggles. Blood flow of the ONH was measured using the Heidelberg retinal flowmeter. RESULTS: The average IOP before, during and after wearing the swimming goggles were 11.88 +/- 2.82mmHg, 14.20 +/- 2.81 mmHg and 11.78 +/- 2.89mmHg, respectively. The IOP increased immediately after putting on the goggles (p < 0.05) and then returned to normal values immediately after removal (p > 0.05). Blood flow of the ONH was 336.60 +/- 89.07 Arbitrary Units (AU) before and 319.18 +/- 96.02 AU after the goggles were worn (p < 0.05). CONCLUSION: A small but significant IOP elevation was observed immediately after the swimming goggles were put on. This elevated IOP was maintained while the goggles were kept on, and then returned to normal levels as soon as they were taken off. Blood flow of the ONH did not change significantly throughout the experiment. These facts should be considered for safety concerns, especially in advanced glaucoma patients.

PURPOSE: Purpose of this study was to analyze research on the service design process applied to domestic medical service areas. METHODS: A review was made through domestic databases including RISS, KISS, DBpia, and NDSL and for the analysis framework: a medical service classification code which integrated the medical service area and the design fields. RESULTS: In the healthcare service field there were 9 studies (69.2%) in the medical area, 1 study (7.7%) each in nursing and oriental medicine, and 2 studies (15.4%) in healthcare. According to analysis results based on the medical service classification code, there were 5 studies in prevention and management, 6 studies in curative care, 1 each in rehabilitation and ancillary care. Double diamond process was used in 8 studies. CONCLUSION: Service design was applied mainly to the curative care in the domestic medical settings but little research on service design in the long-term nursing care area was identified. As a strategy to improve the quality of nursing service, it is necessary to adopt the service design process for various nursing service areas in Korea.

Archives of Plastic Surgery 2020;47(3):203-208
Vascular anomalies are congenital localized abnormalities that result from improper development and maintenance of the vasculature. The lesions of vascular anomalies vary in location, type, and clinical severity of the phenotype, and the current treatment options are often unsatisfactory. Most vascular anomalies are sporadic, but patterns of inheritance have been noted in some cases, making genetic analysis relevant. Developments in the field of genomics, including next-generation sequencing, have provided novel insights into the genetic and molecular pathophysiological mechanisms underlying vascular anomalies. These insights may pave the way for new approaches to molecular diagnosis and potential disease-specific therapies. This article provides an introduction to genetic testing for vascular anomalies and presents a brief summary of the etiology and genetics of vascular anomalies.

OBJECTIVE: To determine anatomical variation of the sural nerve (SN) by ultrasonography (US) and compare sensory nerve action potential (SNAP) of the SN obtained by a control method to that obtained with adjusted method using US. METHODS: Eighty legs of 40 healthy volunteers were enrolled. The location and formation of SN were investigated through US. Two methods of nerve conduction study (NCS) were then performed. In the control method, the cathode was placed 14 cm proximal to the lateral malleolus and the greatest SNAP amplitude was obtained by moving the cathode medially or laterally from just lateral to the calf-mid line. In adjusted NCS, the exact SN union site was stimulated in type 1. In other SN types, the stimulation was done directly over the nerve and the distance from the lateral malleolus was set to be 14 cm. RESULTS: It was found that 73.8% of the SNs were type 1, 22.5% were direct continuation of MSCN (type 2), and 3.8% were MSCN and LSCN without communicating (type 4). However, type 3 was not found. The union point in type 1 SN was 12.6±2.5 cm proximal to the lateral malleolus and 1.4±0.7 cm lateral to the calf-midline. After stimulation adjustment, SNAP amplitude in type 1 SN was significantly increased (20.7±5.5 μV vs. 27.1±6.7 μV). CONCLUSION: Anatomical variation of SN and its location were verified by US. US provides additional information for conducting sural NCS and helps obtain more accurate results.

OBJECTIVES: The clinical manifestations of gout in Korea would be changed lately according to the rapid economical development and the development of diagnostic methods. This study was done to reveal the late clinical features of gout in Korea. METHODS: A retrospective study was done for the 90 gout patients who had been treated in Seoul Paik Hospital from March 1974 to August 1994. Age of onset, sex, duration of disease, serum uric acid level, uric acid concentration of 24 hour urine, joint of first attack, recurrently involved joints, X-ray of involved joint, frequency of tophi, renal ultrasonography, and associated diseases were analyzed. The uric acid levels of the 808 civilians who visited our hospital for the periodic health examination were used as a control value. RESULTS: 1) The serum uric acid level in Korean adults was 5.2+/-1.1mg/dL in male, 3.8+/-0.7mg/dL in female, and 4.7mg/dL in general. The serum uric acid concentration of the gout patients was 8.6+/-2.2mg/dL in male, 6.1+/-2.1mg/dL in female, and 8.5+/-2.3mg/dL in general. The age of onset was 46.4+/-12.9 years old and male to female ratio was 44: 1 2) The renal excretion of uric acid was 470+/-173 mg/day in gout patients. 3) The sites of first attack were first MTP joint(76%), tarsal joint(13%), knee(5%), and other MTP joints(5%) 4) The involved joints during the repeated attacks were first MTP joint(84%), tarsal joint(23%), and fingers(23%), The duration of disease was significantly longer and the serum uric acid concentration was higher in the patients with tophi than they are in the patients without. 5) The 4l% of patients showed hone change in X-ray. 6) The renal ultrasound examinations were abnormal in 42% of the patients and the serum uric acid concentrations were significantly higher. 7) Obesity was found in 68% of patients, hypertension in 39%, hyperlipidemia in 16%, and chronic renal disease in 12%. CONCLUSION: The clinical features of gout in our study were similar to those of others done in and out of Korea, except that the frequency of hypertringlyceridemia was much lower than that of the foreign countries.

PURPOSE:
The utility of 18-fluordesoxyglucose positron emission tomography ([¹â¸F]-FDG-PET) combined with computer tomography or magnetic resonance imaging (MRI) in gastric cancer remains controversial and a rationale for patient selection is desired. This study aims to establish a preclinical patient-derived xenograft (PDX) based [¹â¸F]-FDG-PET/MRI protocol for gastric cancer and compare different PDX models regarding tumor growth and FDG uptake.
MATERIALS AND METHODS:
Female BALB/c nuu mice were implanted orthotopically and subcutaneously with gastric cancer PDX. [¹â¸F]-FDG-PET/MRI scanning protocol evaluation included different tumor sizes, FDG doses, scanning intervals, and organ-specific uptake. FDG avidity of similar PDX cases were compared between ortho- and heterotopic tumor implantation methods. Microscopic and immunohistochemical investigations were performed to confirm tumor growth and correlate the glycolysis markers glucose transporter 1 (GLUT1) and hexokinase 2 (HK2) with FDG uptake.
RESULTS:
Organ-specific uptake analysis showed specific FDG avidity of the tumor tissue. Standard scanning protocol was determined to include 150 μCi FDG injection dose and scanning after one hour. Comparison of heterotopic and orthotopic implanted mice revealed a long growth interval for orthotopic models with a high uptake in similar PDX tissues. The H-score of GLUT1 and HK2 expression in tumor cells correlated with the measured maximal standardized uptake value values (GLUT1: Pearson r=0.743, P=0.009; HK2: Pearson r=0.605, P=0.049).
CONCLUSIONS
This preclinical gastric cancer PDX based [¹â¸F]-FDG-PET/MRI protocol reveals tumor specific FDG uptake and shows correlation to glucose metabolic proteins. Our findings provide a PET/MRI PDX model that can be applicable for translational gastric cancer research.

BACKGROUND: We reviewed the guidelines for the transfusion of red cells, platelets, and fresh frozen plasma (FFP) of the Korean Society of Blood Transfusion and modified the previous guidelines for transfusions at our hospital. We evaluated the appropriateness of the current hospital transfusions with these algorithms based on these guidelines. METHODS: The medical records of 266 transfusion episodes of patients receiving transfusions of red cells (144), platelets (61), and FFP (61), were reviewed retrospectively at Ewha Womans University Mokdong Hospital during 2002. RESULTS: Inappropriateness rates for transfusion episodes were 2.8% for red cells, 4.9% for platelets, and 44.3% for FFP. 144 red cell transfusions comprised 73 episodes (50.7%) in acute blood loss and 71 (49.3%) in chronic anemia. Among them, 2 episodes in each condition were assessed as inappropriate, respectively. 61 platelet transfusions comprised 32 episodes (52.5%) for a prophylaxis in marrow failure and 13 (21.3%) for active bleeding and 6 (9.8%) for acute disseminated intravascular coagulation (DIC) and 10 (16.4%) for others. Among them, 3 episodes for clinical bleeding were assessed as inappropriate. Out of 61 FFP transfusions, 34 episodes (56%) (16 liver disease with complications, 11 acute DIC, and 7 others) were assessed as appropriate and 27 episodes (44%) (8 liver diseases without complications, 10 surgical procedures and 9 others) were assessed as inappropriate. CONCLUSIONS: We modified our previous guidelines for transfusions according to the transfusion guidelines proposed by the Korean Society of Blood Transfusions. These guidelines could be easily applied to evaluate the appropriateness of transfusions performed at our hospital and to specify the cases of inappropriate transfusions.

The aim of this study was to investigate the acute effects of ethanol administration on pattern-reversal visual evoked potential (VEP) and multifocal electroretinography (mfERG). Fifteen healthy subjects with no ocular or general disease were recruited. VEP (0.25° pattern sizes) and mfERG with 19 elements in two recording segments were performed before ethanol administration to obtain baseline for each participant. A few days later, the participants visited again for VEP and mfERG measurements after ethanol administration. Ethanol (0.75 g/kg) was administered orally over the course of 30 minutes. VEP and blood alcohol concentration were evaluated one hour after ethanol administration, and mfERG was conducted after pupil dilation. The Wilcoxon signed-rank test was used to compare parameter changes after randomized eye selection. The mean blood alcohol concentration was 0.034% ± 0.05% by volume. VEP revealed a P100 latency delay (109.4 ± 5.3; 113.1 ± 8.2; P = 0.008) after alcohol administration. The P1 implicit time of ring 1 on mfERG showed a trend of shortening after alcohol administration (37.9 ± 1.0; 37.2 ± 1.5; P = 0.048). However, the changes did not show statistical significance after Bonferroni correction. In conclusion, orally administrated ethanol (0.75 g/kg) appears to suppress the central nervous system, but it is not clear whether alcohol intake affects the retina.

A 69-year-old man was admitted to our hospital for deep vein thrombosis, and he had experienced two episodes of left leg swelling: one happened after an 11 hour-air trip from Europe in June 2007, and the other developed 3 days after an operation for a herniated lumbar disc in July 2007. We treated him for a deep vein thrombosis of the deep femoral vein after admission. However, we arrived at the final diagnosis of angioleiomyosarcoma after the operation for the tentative diagnosis of deep vein thrombosis. We removed the firmly engorged deep femoral vein on the second operation. We report here on a case of angioleiomyosarcoma that arose from the deep femoral vein.
