Background/Aims: Beta-lactam (BL) antibiotics are widely prescribed for controlling bacterial infections and relevant culprits of adverse drug reactions (ADRs). BL allergy may vary according to prescription patterns within a given period of time. However, BL allergy in contemporary clinical practice has rarely been a focus of research. Methods: To investigate the clinical characteristics of BL allergy, subjects with ADRs to medicines, including BL antibiotics, were retrospectively reviewed. Results: Among the 175 enrolled subjects, BL antibiotics as culprits were confirmed in 79 (45.1%, female 53.2%, age 49 ± 14 years). Among the patients with confirmed BL allergy, only two (2.5%) were diagnosed via a prescription survey completed as part of multi-drug administration. The others were confirmed by serologic tests in 33 patients (41.8%), skin tests in 29 (36.7%), and drug provocation tests in 15 (19.0%). Regarding the symptoms and signs, onset within an hour of taking medicines was common (61 patients, 77.3%). Itchy skin was most common, followed by hives, rash, breathing difficulty, angioedema, and hypotension. Anaphylaxis occurred in 67%, and one-half (50.6%) of patients visited the emergency room. Cefaclor and amoxicillin were common BL culprits. Among others who did not have BL allergy, nonsteroidal anti-inflammatory drugs were found to be common culprits, followed by quinolones. Conclusions BL allergy is common among patients who experienced ADRs to medicines including BL antibiotics. For multi-drug administration, a prescription survey hardly helped in confirming BL allergy. Anaphylaxis is common in patients with BL allergy, frequently leading to emergency room visits. Cefaclor and amoxicillin are common culprits.

PURPOSE: This study was to identify the stages of change in smoking cessation behavior and factors associated with the stages of smoking cessation behavior according to the trans-theoretical model. METHODS: The subjects were 154 industrial workers working at H Industry in N City, Chonnam Province who were currently smoking and had smoked in the past. Data were analyzed by descriptive statistics, ANOVA, and Duncan's multiple comparison test using SAS Version 10.0. RESULTS: The subjects were distributed among the stages of change in smoking cessation behavior: there were 28 subjects (18.2%) in the precontemplation stage, 71 (46.1%) in the contemplation stage, 21 (13.6%) in the preparation stage, 8 (5.2%) in the action stage, and 26 (16.9%) in the maintenance stage. The amount of smoking per day, self-efficacy, and advantages (pros) of smoking were significantly associated with the stage of change in smoking cessation behavior. CONCLUSION: This study suggested that the stage of change in smoking cessation behavior of the subject should be identified prior to the application of intervention programs, nursing intervention strategies should be considered to reduce the amount of smoking per day, and the disadvantages of smoking should be perceived.

Treatment-resistant schizophrenia (TRS) has been defined as the persistence of positive symptoms despite two or more trials of antipsychotic medication of adequate dose and duration. TRS is a serious clinical problem and occurs in approximately 30% of patients with schizophrenia. It is important that patients who do not adequately respond to antipsychotics be reevaluated to exclude or address causes other than non-responsiveness to medication, that is, the possibility of pseudo-resistance. In particular, non-adherence to oral antipsychotic treatment should be monitored to rule out pseudo-resistant cases of TRS. Moreover, patients with TRS who take their medication as required may have subtherapeutic antipsychotic plasma levels, secondary to pharmacokinetic factors. In this paper, we review the concept and exclusion of pseudo-resistance, especially owing to non-adherence or pharmacokinetic factors, and present methods to enhance drug adherence.

In most cases, persistent left superior vena cava (PLSVC) is asymptomatic and discovered accidentally. This case involves a 43-year-old male who underwent an emergency cadaveric liver transplantation. Postoperatively, the left internal jugular vein was cannulated using a sono-guided Seldinger technique in the intensive care unit. But the chest X-ray showed that the catheter followed the left paramediastinal course instead of crossing midline to the right to enter the superior vena cava. In consideration of the patient's status, an intra-arterial or extra-vascular placement could be excluded. For a diagnosis, we performed a bed-side transthoracic echocardiography with an agitated saline micro-bubble test. When agitated saline was injected through the catheter, the coronary sinus was initially opacified, and then the right atrium followed. In conclusion, we were able to make a diagnosis of PLSVC by a bedside test without radiation exposure.

The Dia and Mia antigens have been detected in Koreans with a frequency of 6.4∼14.5% and 0.9%, respectively. This study evaluated the effectiveness of different screening cells using the cells with Diaand Mia antigens for unexpected antibody screening. An unexpected antibody-screening test was performed separately using different screening cells, including the Dia antigen (Panel D) and Mia antigen (Panel M). A total of 2,077 specimens from 1,847 patients were collected, among which 49 (2.32%) and 43 (2.08%) were positive using Panel D and Panel M, respectively. Twenty-seven patients were positive with both panels, 2012 were negative with both panels, and thirty-eight patients showed a discordant result. The suspected anti-Diaand anti-Mia were detected in 4 (0.19%) and 5 (0.24%) patients, respectively. Therefore, the frequency of anti-Dia and anti-Mia antibodies in this study may be helpful for selecting unexpected antibody screening reagents.

Background: As the role of immunotherapies and personalized medicine grow, cancer patients have faced many choices in treatments and have suffered financial toxicity. These challenges brought the need for the value framework (VF) to guide treatment decision making. Methods: A survey was taken to 102 oncologists about perception for VF. They were asked about priorities among several considerations when they prescribe cancer drugs. Their views on the need for development and potential implications of VF in Korea were assessed, also. Results: The survey shows that 90% of the respondents choose clinical efficacy as the most important value in cancer drugs selection, and the cost of drug was more weighted value in immune checkpoint inhibitors (13.7%). Approximately half (53.9%) answered that they were aware of the existing VFs. Over 90% of respondents agreed with the need for development of a VF for cancer drugs based on Korean healthcare system and further usefulness for decisions about reimbursement issues. Seventy-one percent answered that two representative VFs (American Society Clinical Oncology-VF and European Society for Medical OncologyMagnitude of Clinical Benefit Scale) should be reflected in value measurement of cancer drugs in Korea. Conclusion The Korean oncologists recognized the necessity for the clinical application of VF. Further discussion between the stakeholders should be followed to alleviate the financial burden through the value-based decision making of cancer drugs.

Background: Little is known about the surgical discipline in North Korea from the perspective of the outside world. This study aimed to examine the disease entities covered by articles published in the major medical journal in North Korea, “Surgery.” Methods: Content and frequency analyses of 2,132 articles published in “Surgery” from 2006 to 2017 were conducted. Two medical doctors who majored in Surgery and anesthesiology perused the articles and compiled the diseases being elucidated in each article. The diseases described in each article were stratified into 13 surgical subspecialties. Results: Articles from “Surgery,” similar to articles from the Western surgical community, also covered a wide variety of surgical diseases from different subspecialties, and the number of publications continued to grow consistently. Moreover, a number of studies focused on the fields of orthopedics and general Surgery dealing with benign diseases. Some articles focused on minimally invasive surgeries using laparoscopy. Conclusion The studies published in the North Korean journal “Surgery” encompass various clinical areas, but their quality is unclear.
