Atrophic gastritis (AG) and intestinal metaplasia (IM) are the main precursor lesions of gastric cancer as the incidence of gastric cancer increases in the gastric mucosa involved with AG and IM. The prevalence of AG and IM vary depending on countries, even it represents diverse results in the same nation. Usually AG is antecedent of IM but the etiologies of AG and IM are not always the same. The sensitivity and specificity of diagnostic methods to detect AG and IM are different. Furthermore, the management strategy of AG and IM has not been established, yet. Helicobacter pylori infection has been proved as the most important cause of AG and IM. Thus the eradication of H. pylori is very important to prevent the progression to gastric cancer which is still placed in the high rank in morbidity and mortality among cancers. However, the reversibility of AG and IM by eradication of H. pylori which was assumed to be certain by meta-analysis is; however, controversial now. Therefore, the understanding and early diagnosis of AG and IM are very important, especially, in high incidence area of gastric cancer such as Republic of Korea.

Here, we report a rare case of L3 chordoma progressed to an intradural extramedullary (IDEM) mass and distant metastasis to the fascia lata. A 64-year old female patient presented to a local university hospital due to back pain and received excisional biopsy for a L3 destructive bony lesion. Local radiation therapy was initially administered, assuming a malignancy of unknown origin, but she developed cerebrospinal fluid leakage during adjuvant radiation therapy, which was managed by wound revision and lumbar drainage. As the destructive lesion progressed, she visited our hospital for a second opinion 3 months after the biopsy. After review of outside pathology, we diagnosed the lesion to be a chordoma, and performed a L3 corpectomy with cage and plate fixation. One and a half years later, positron emission tomography and computed tomography (PET-CT) revealed a right tensor fascia lata hypermetabolic lesion. Excisional biopsy confirmed a distant metastasis of the chordoma. One year later, she complained of L2 radiating pain. PET-CT and CT myelogram revealed an IDEM lesion. Surgical excision confirmed the transdural invasion of the chordoma. To our knowledge, this is the first report of an iatrogenic IDEM invasion and distant metastasis to the tensor of the fascia lata by a L3 chordoma.

OBJECTIVE: The visually impaired have limited access to health care services and related information, and thus, they can have serious hurdles against properly taking medications. Despite that it is important to improve self-care ability of the visually impaired for correct medication use, there have been few studies investigating their needs for health care services in Korea, particularly focusing on proper medication usage. This study is to explore safety-related issues regarding mediation usage among the visually impaired based on in-depth interview. We particularly focus on any obstacles for safe use of medicines including experience on medication-related adverse effects in order to provide preliminary evidence for policy measures to improve proper medication use among the visually impaired. METHODS: Study sample was visually impaired individuals who resided in Seoul area and were registered in the National Association of Visually Impaired. The association helped the process of recruiting the study participants. In-depth interview for each study participants was conducted. Each interview was recorded and later converted into a written script to extract core contents for the analysis. RESULTS: The study participants comprised of three women (42.9%) and four men (57.1%). One was in his 20's, and there were four participants in 30's and two in 40's. Fully impaired participants were majority (5 out of 7). Limitation to physical access to health care providers and health information were the key factors to hamper safe medication utilization among the study participants. Difficulty reading medication information and may take the wrong medication or incorrect doses of medication, resulting in serious consequences, including overdose or inadequate treatment of health problems. Visually impaired patients report increased anxiety related to medication management and must rely on others to obtain necessary drug information. Pharmacists have a unique opportunity to pursue accurate medication adherence in this special population. This article reviews literature illustrating how severe medication mismanagement can occur in the visually impaired elderly and presents resources and solutions for pharmacists to take a larger role in adherence management in this population. CONCLUSION: The visually impaired had difficulties reading medication information and identifying medicines, and took incorrect doses of medications. Public support for safe medication use and medication management among the visually impaired is necessary.

BACKGROUND: The recent change in pharmaceutical education system following the paradigm shift to patient-oriented pharmacy service requires an in-depth discussion to reorganize a future direction and establish a basis for maximizing social values of community pharmacy service. OBJECTIVE: This study was conducted to review the current status of community pharmacy service provision in Korea based on published literatures. METHODS: The electronic databases of National Digital Science Library and Electronic National Assembly Library were used to search the journal articles and dissertation papers. A search term "community pharmacy" was used and the published period was limited to papers published after year 2001, when the legal separation of prescribing and dispensing was implemented. Relevant study reports were also searched manually. Information about pharmacy service provision and study outcomes were retrieved from the selected papers, and classified by predefined individual service scope. RESULTS: A total 33 papers reporting services provided by community pharmacies were selected (journal article 11, dissertation paper 17, and study report 5). Pharmacy services identified in these papers could be classified into prescription dispensing service, pharmaceutical care service, self medication service, other products service, and health promotion service. Twenty papers reported prescription dispensing services, three papers reported pharmaceutical care service, and only two papers reported health promotion service. Current community pharmacy services are highly dependent on prescription drugs while expanded services such as pharmaceutical care and health promotion are peripheral. Most prevalent research topic was medication counseling service (18 papers), reflecting that community pharmacists generally consider it to be the most important and fundamental service. Overall, current pharmacy services are very limited and focus on prescription dispensing service. CONCLUSION: At this point of time requiring expansion and quality improvement of community pharmacy services, we suggest further lively discussion to strengthen pharmacist's functional identity and set conditions for providing socially expected services.

BACKGROUND: Although a growing number of guidelines and clinical researches are available for immunosuppressive treatment of post-transplantation, there is no clinical practice guideline for the care of kidney transplant recipients in Korea. Selection of a researchable question is the most important step in conducting qualified guideline development. Thus, we aimed to formulate key questions for Korean guideline to aid clinical decision-making for immunosuppressive treatment. METHODS: Based on previous published guidelines review, a first survey was constructed with 29 questions in the range of immunosuppressive treatments. The experts were asked to rate the clinical importance of the question using a 5-point Likert scale. The questions reached 60% or more from the first survey and additional new questions were included in the second survey. In analyzing the responses to items rated on the 9-point scale, consensus agreement on each question was defined as 75% or more of experts rating 7 to 9. RESULTS: In the first survey, 50 experts were included. Among the 29 questions, 27 were derived to get 60% or more importance and 3 new questions were additionally identified. Through the second survey, 9 questions were selected that experts reached consensus on 75% and over of the options. Finally, we developed key questions using PICO (patient, intervention, comparison, and outcome) methodology. CONCLUSION: The experts reached a high level of consensus on many of key questions in the survey. Final key questions provide direction for developing clinical practice guideline in the immunosuppressive treatment of transplantation.

Background/aims: Contradictory findings on the association between cholecystectomy and cancer have been reported. We aimed to investigate the risk of all types of cancers or site-specific cancers in patients who underwent cholecystectomy using a nationwide dataset. Methods: Subjects who underwent cholecystectomy from January 1, 2007, to December 31, 2014, who were older than 20 years and who underwent an initial baseline health check-up within 2 years were enrolled. Those who were diagnosed with any type of cancer before the enrollment or within 1 year after enrollment were excluded. Ultimately, patients (n=123,295) who underwent cholecystectomy and age/sex matched population (n=123,295) were identified from the database of the Korean National Health Insurance Service. The hazard ratio (HR) and 95% confidence interval (CI) for cancer were estimated, and Cox regression analysis was performed. Results: The incidence of cancer in the cholecystectomy group was 9.56 per 1,000 person-years and that in the control group was 7.95 per 1,000 person-years. Patients who underwent cholecystectomy showed an increased risk of total cancer (adjusted HR, 1.19; 95% CI, 1.15 to 1.24; p<0.001), particularly leukemia and malignancies of the colon, liver, pancreas, biliary tract, thyroid, pharynx, and oral cavity. In the subgroup analysis according to sex, the risk of developing cancers in the pancreas, biliary tract, thyroid, lungs and stomach was higher in men than in women. Conclusions Physicians should pay more attention to the possibility of the occurrence of secondary cancers among patients who undergo cholecystectomy.

Objective: Owing to prolonged social distancing and the resultant isolation, the prevalence of depression and suicidality has increased during the COVID-19 pandemic. This study aimed to investigate the severity of depression and suicidality in Korean community populations and examine their awareness of suicide and suicide prevention during the pandemic. Methods: This study surveyed a community population in 2020 and 2021, involving 668 participants. We evaluated the severity of depression and suicidality using the Patient Health Questionnaire-9 and Beck Scale for Suicidal Ideation as well as questions about awareness of suicide. We performed a correlation analysis to confirm the association between variables, and compared participants’ suicide awareness according to the severity of depression. Results: The severity of depression and suicidality in the community population decreased in 2021 compared to 2020. Awareness of the importance of suicide prevention increased in 2021, but the percentage reporting that it is possible decreased slightly. The group with higher depressive symptoms reported a lower possibility of suicide prevention. Conclusion Increasing social interest in suicide, as well as awareness of suicide prevention, is important for reducing suicide rates. Suicide prevention campaigns, education, and social policies are needed, particularly during the pandemic.

Objectives: South Korea has the highest suicide rate among Organisation for Economic Co-operation and Development countries; there is an increasing trend in suicide attempts among middle and high school students. Various factors contribute to the risk of suicide among adolescents, and the perception of suicide prevention has emerged as a significant factor. This study aimed to investigate the association between emotional and behavioral difficulties among middle and high school students and their perceptions of suicide prevention and to explore differences in suicide perception according to age. Methods: A survey was conducted among community middle and high school students, including 530 participants, between 2020 and 2021. Emotional and behavioral difficulties were assessed using the Strengths and Difficulties Questionnaire-Korean version, and participants were asked to complete a questionnaire on the importance and possibility of suicide prevention. A correlation test and analysis of variance were used to examine the relationships between the variables, and suicide awareness was compared according to age. Results: The participants who displayed higher strength or lower difficulty were more likely to respond positively to suicide prevention measures. They also exhibited high strength and low difficulty levels, thus agreeing with the importance of suicide prevention. Regarding age-related perceptions of suicide, adults aged 20–29 years reported the lowest probability of suicide prevention. Conclusion Suicide perceptions influence the incidence of suicide. Therefore, active societal engagement through suicide prevention campaigns and related education is essential to improve such perceptions. Continuous attention and support are required to address this issue.

BACKGROUND: Because of recent advances in the molecular diagnosis of cancer patients, tissue quality has become more important in daily practice. METHODS: To evaluate the effects of fixative, duration of fixation, decalcification, and storage periods on nucleic acid integrity, DNA and RNA were extracted from gastrointestinal cancer tissue. The yield and purity were analyzed, and polymerase chain reaction (PCR) for glyceraldehyde 3-phosphate dehydrogenase (GAPDH; 60 bp), beta-actin (148 bp), and human growth hormone (hGH; 434 bp) and real-time reverse transcription-PCR for beta-actin (97 bp) were performed. RESULTS: All formalin-fixed paraffin-embedded (FFPE) and methacarn-fixed paraffin-embedded (MFPE) samples tested positive for GAPDH and beta-actin by PCR. hGH was successfully detected in all MFPE samples, but in only 46.7% of the FFPE samples. Prolonged formalin fixation resulted in fewer GAPDH and beta-actin PCR products, and amplification of hGH was not successful. The PCR and reverse transcription-PCR results were significantly affected by the duration of decalcification. The yield, purity, and integrity of mRNA progressively decreased with increased storage periods of paraffin blocks. CONCLUSIONS: Fixation and storage should therefore be standardized in order to improve the quality of molecular pathologic diagnosis.

BACKGROUND/AIMS: Functional dyspepsia (FD) is a gastrointestinal disorder in which the patient suffers from chronic abdominal symptoms despite the absence of organic disease. Benachio Q solution (soln.)(R) is a new prokinetic herbal medicine. The aim of the present study is to determine the efficacy and safety of Benachio Q soln.(R) in patients with postprandial distress syndrome (PDS) subtype in FD. METHODS: A single-center, randomized, double-blind, placebo-controlled pilot study was performed in 20 patients with PDS. Patients were assigned to receive either Benachio Q soln.(R) or placebo three times a day. After 4 weeks of treatment, the data on response rates, symptoms severity of PDS and gastric emptying time were analyzed to evaluate its efficacy. Adverse events, laboratory tests and vital sign were analyzed to assess its safety. RESULTS: Nine patients were assigned to Benachio group and 10 patients to placebo group. The response rate after 4 weeks was 44.4% and 20.0% in Benachio and placebo group, respectively (p=0.350). The response rate during the first week in Benachio group was better compared to that of placebo group with marginal difference (33.3% vs. 0.0%, p=0.087). Changes of severity score in early satiety on second and third week were -1.8+/-0.6, -1.9+/-0.4 and -1.3+/-0.5, -1.4+/-0.6 in Benachio and placebo group, respectively (p=0.059 vs. p=0.033). No adverse event was observed. CONCLUSIONS: The new herbal drug, Benachio Q soln.(R) seems to improve the symptoms of PDS subtype in FD and could be used safely. Further larger trial is needed in the future.
