BACKGROUND: Korea has high prescribing rate and rising antibiotic resistance. This study was conducted to understand why primary physicians prescribe antibiotics for acute respiratory infections and to explore the factors that influence antibiotic resistance, and so to suggest strategy to reduce antibiotic resistance. METHODS: A qualitative exploratory approach was used using 4 focus groups composed of physicians from different area. A semi-structured guide was applied in obtaining the physicians' opinions. Common themes were extracted by authors, which were used to gather results and draw conclusion. RESULTS: Participants acknowledged multiple factors such as clinical factor and competitive environment are involved in physicians' decision of antibiotic prescribing. They identified that causes of rising antibiotic resistance were shortage of information, discontinuation of taking antibiotics, and other system factors. CONCLUSION: Participants were certain that less prescribing antibiotics and selecting appropriate antibiotics might be method to reduce antibiotic resistance. To change the prescribing behavior, it should be provided periodically for community physicians with prescribing information and specific guidelines for antibiotics resistance. Patients should be also noticed about antibiotic medication information more accurately. Including prescription incentive policy, improvement of healthcare system will be carried out at the same time.

PURPOSE: The purpose of this study was to examine the effect of lifestyle intervention on the development of fatigue, nutritional status and quality of life of patients with gynecologic cancer. METHODS: A nonequivalent control group quasi-experimental design was used. Participants were 49 patients with gynecologic cancer. They were assigned to the experiment group (n=24) or the control group (n=25). The lifestyle intervention for this study consisted of physical activity, nutritional education, telephone call counseling, health counseling, monitoring for lifestyle, and affective support based on Cox's Interaction Model of Client Health Behavior and was implemented for six weeks. RESULTS: Significant group differences were found for fatigue (p =.037), nutritional status (p =.034) and social/family well-being (p =.035) in these patients with gynecologic cancer. CONCLUSION: Results indicate that this lifestyle intervention is effective in lessening fatigue, and improving nutritional status and social/family well-being. Therefore, nurses in hospitals should develop strategies to expand and provide lifestyle interventions for patients with cancer.

Sodium and potassium intake was assessed on the basis of its respective excretion levels in 24 hr urine samples. However, owing to the inconvenience of collection, we evaluated random spot urine for alternative sodium and potassium excretion markers. We included 250 patients who submitted 24 hr- and spot urine for clinical tests. However, 22 patients who showed 24 hr urine creatinine excretion levels <500 mg/day were excluded, because these samples possibly resulted from incomplete urine collection. Moreover, 24 patients were excluded because of their use of diuretics during the urine collection period. We observed significant correlations between 24 hr urine sodium excretion and both the sodium/creatinine (r=0.34, P<0.0001) and the sodium/specific gravity unit (SGU) ratios (r=0.19, P=0.007) in random urine samples. Similarly, 24 hr urine potassium excretion and both the spot urine potassium/creatinine (r=0.47, P<0.0001) and potassium/SGU ratios (r=0.28, P<0.0001) were significantly correlated. Although the estimated sodium/creatinine and potassium/creatinine ratios showed a significant correlation with 24 hr urine sodium and potassium excretion, respectively, further studies are required to develop a spot urine test for individualized monitoring of sodium and potassium excretion.

OBJECTIVES: To suggest direction for improving policies by understanding current management of narcotics or psychotropic drugs and analyzing their distributions and usage. METHOD: We conducted a comparison analysis between health insurance claims and the amount supplied to health care institutions for narcotics or psychotropic drugs through health insurance claims data and drug distribution supply data from 2010 to 2012 collected from Korea Pharmaceutical Information Service Center (KPIS). Furthermore, we carried out literature investigation and online search to comprehend the current management of narcotics drugs in Korea. RESULTS: The amount supplied to medical institutions for all drugs in 2012 was 19.4 trillion won, which increased from 19.5 trillion in 2011 by 0.54%. For narcotic drugs, the amount supplied was 318.4 billion won in 2011 and increased to 335.1 billion won by 5.3% in 2012, which exceeded the rate of increase for the amount supplied for all drugs. The proportion of amount claimed in the total amount supplied to medical institutions for all drugs was 60.5% in 2012, whereas the proportion of amount claimed for narcotic drugs was 55.6%, which showed that narcotic drugs were used relatively less within health insurance. Furthermore, management of the current domestic distribution supply data focuses on manufacturing and medical institution supply stages. CONCLUSION: Hereafter, the management of narcotics or psychotropic drugs needs to be improved by reinforcing active monitoring in optimal prescription and usage in patients by collecting and analyzing information on drug usage of patients.

Spontaneous isolated celiac artery dissection (SICAD) is a rare condition that is characterized by sudden onset abdominal pain, typically occurring in middle-aged men. Although its clinical course is mostly benign, it may progress to true lumen occlusion. No established therapeutic guidelines are available for SICAD associated with splenic infarction. This report describes two patients who presented with sudden onset abdominal pain and were diagnosed with SICAD with splenic infarction based on computed tomography (CT) findings. Patients were treated with bowel rest and anticoagulants. After a week of medical therapy, the abdominal pain resolved. Follow-up CT revealed no progression of the dissection flap. The patients received oral anticoagulants for 3 months and did not experience any symptom recurrence. Medical therapy with anticoagulants may be considered for patients with SICAD and splenic infarction. Associated splenic infarction itself is not an indication for endovascular or surgical intervention for SICAD.

Hematopoietic stem cell transplantation remains the only curative option for myelodysplastic syndrome (MDS), but the prevalence of the disease in elderly people limits broad application of the procedure, particularly in lower risk group. Azacitidine has been recently approved by the U.S. Food and Drug Administration for MDS regardless of subtype on French-American-British classification. Adverse effects of azacitidine include gastrointestinal, hematological and infusion-related reactions. Azacitidine induced hepatotoxicity has been reported mainly in patients with previous hepatobiliary disease, e.g., extensive tumor infiltration in liver, liver cirrhosis and cholelithiasis. We report here a case of azacitidine-induced hepatitis under no predisposition to hepatobiliary disease.

Purpose: To evaluate the long-term maintenance rate and associated factors of silicone punctal plugs in patients with Sjögren’s syndrome (SS). Materials and Methods: We retrospectively reviewed the medical records of 163 patients with SS who underwent silicone punctal plug insertion between December 2013 and July 2021 at Severance Hospital. The status of punctal plug insertions was classified into the following three categories by the clinician: maintenance, spontaneous loss, and intended removal. Cox proportional hazards model was used to evaluate the risk factors for spontaneous loss. Results: The mean maintenance period was 12.8±15.3 (median 7.07) months. The rate of spontaneous loss was 58%, and the rate of punctal plug removal by the clinician was 14%. The number of prior plug insertions was a risk factor for spontaneous loss [hazard ratio (HR) 1.055, p=0.035]. The upper eyelid punctum was at a higher risk than the lower one (p=0.042). Small-sized plugs showed a significantly higher risk for spontaneous loss than large-sized ones (HR 1.287, p=0.035). Flow-controller type plugs were more vulnerable to spontaneous loss than complete occluders [Micro FlowTM vs. EagleFlex® (HR 2.707, p=0.008) and Micro FlowTM vs. UltraplugTM (HR 3.402, p=0.005)]. The most common reason for removal was tear overflow (5.6%). Conclusion In repeated insertion, characteristics of the punctal plug, including the type and size, and location of plug insertion, influenced the spontaneous loss of plugs. The management of punctal plugs, including insertion, maintenance, and removal, requires personalized strategies for versatile situations.

Background: Postpartum hemorrhage is the leading cause of maternal mortality. Oxytocin being the most popular uterotonic agent, has been routinely administered after both vaginal delivery and cesarean section. Carbetocin is a newer uterotonic agent and provides the benefit of a longer duration of action without additional administration post-delivery. Methods: We recruited 34 women undergoing elective cesarean section under spinal anesthesia. All patient was received spinal anesthesia using 0.5% hyperbaric Marcaine 8–10 mg in conjugation with fentanyl 20 μg in the left lateral decubitus position. Hartmann’s solution 10–15 ml/kg was administered before carbetocin. The operation started as soon as sensory block at level T4–T6 was confirmed. A non-invasive hemodynamic monitoring cuff (Finometer®) was attached to the patient’s finger soon after the induction of spinal anesthesia. Using the Finometer, we recorded the heart rate and mean arterial pressure at every 15 s, starting from 15 s before the administration of carbetocin to 5 min after. After the removal of the placenta, the bolus group was administered intravenous bolus injection of carbetocin 100 μg and the infusion group was administered carbetocin 100 μg diluted in 50 ml normal saline, over 5 min using an infusion pump. Results: The demographic data showed no significant difference between the two groups. Furthermore, there were no significant hemodynamic differences between the two groups. Conclusions The method of administration of carbetocin does not influence its hemodynamic effects.

Purpose: This study aimed to investigate the incidence of early failure of vascular access for hemodialysis, and determine which factors measured in duplex ultrasound study could predict early failure. Methods: We performed a retrospective review of patients who underwent arteriovenous fistula (AVF) or arteriovenous graft (AVG) creation for hemodialysis between September 2019 and January 2023. Early failure was defined as any event that required surgical or endovascular intervention within 6 months following AVF or AVG creation. Results: A total of 189 patients were included. Early failure occurred in 36 patients (19.0%), which included 22 AVFs and 14 AVGs. In the patients who underwent AVF, the preoperative venous diameter, postoperative venous and arterial diameters, and flow volume of AVF all were significantly smaller in the early failure group compared to the patent group.In AVG, the preoperative venous diameter was the only parameter that differed between the 2 groups. A sonographic score was defined based on these factors. In a multivariable analysis, male sex, a previous history of AVF or AVG creation, and sonographic score were found to be significantly associated with early failure. The postoperative venous diameter in AVF and the preoperative venous diameter in AVG were highly predictive of early failure (areas under the curves 0.92 and 0.82, respectively). Conclusion Venous diameter measured 6 weeks following AVF operation and preoperative venous diameter in AVG were highly predictive of early failure among the duplex ultrasound parameters. Surveillance strategies in the early phase following vascular access creation can be based on these factors.

PURPOSE: The aim of this study was to evaluate the improvement of osteogenic potential of biphasic calcium phosphate (BCP) bone substitute coated with synthetic cell-binding peptide sequences in a standardized rabbit sinus model. METHODS: Standardized 6-mm diameter defects were created bilaterally on the maxillary sinus of ten male New Zealand white rabbits, receiving BCP bone substitute coated with synthetic cell binding peptide sequences on one side (experimental group) and BCP bone substitute without coating (control group) on the other side. Histologic and histomorphometric analysis of bone formation was carried out after a healing period of 4 or 8 weeks. RESULTS: Histological analysis revealed signs of new bone formation in both experimental groups (4- and 8-week healing groups) with a statistically significant increase in bone formation in the 4-week healing group compared to the control group. However, no statistically significant difference in bone formation was found between the 8-week healing group and the control group. CONCLUSIONS: This study found that BCP bone substitute coated with synthetic cell-binding peptide sequences enhanced osteoinductive potential in a standardized rabbit sinus model and its effectiveness was greater in the 4-week healing group than in the 8-week healing group.
