Crohn’s disease (CD) is a relapsing and progressive condition characterized by diarrhea, abdominal pain, weight loss, and hematochezia that results in serious complications such as perforations, fistulas, and abscesses. Various medications, interventions, and surgical treatments have been used to treat CD. The Korean guidelines for CD management were distributed in 2012 and revised in 2017 by the Inflammatory Bowel Disease (IBD) Research Group of the Korean Association for the Study of Intestinal Diseases. Substantial progress in mucosal immunologic research has elucidated the pathophysiology of IBD, leading to development of biological agents for treatment of CD. The first developed biologic agent, tumor necrosis factor-α agents, were shown to be efficacious in CD, heralding a new era in management of CD. Subsequently, vedolizumab, a monoclonal antibody against integrin α4β7, and ustekinumab, a human monoclonal antibody that inhibits the common p40 subunit of interleukin-12 and interleukin-23, were both approved for clinical use and are efficacious and safe for both induction and maintenance of remission in moderate-to-severe CD patients. Moreover, a recent study showed the non-inferiority of CT-P13, an infliximab biosimilar, compared with infliximab in CD patients. The third Korean guidelines for CD management provide updated information regarding treatment of moderate-to-severe CD patients with biologic agents.

Background: Most unintentional injuries that occur at home are preventable. However, it may be difficult to sufficiently reduce the number of falls occurring at home by only identifying risk factors focused on specific age groups. Therefore, this study aimed to identify the risk factors (especially age and places where injuries occurred at home) for intracranial injury (ICI) caused by unintentional falls at home. Methods: Using the Emergency Department (ED)-Based Injury In-depth Surveillance, we analyzed the data of patients who visited the ED due to unintentional falls at home. Risk factors were identified using multivariable logistic regression according to age groups and interactions between place of injury occurrence and age groups, and sex and age groups were assessed. Results: In total, 232,124 patients were included in the analysis; older adults had a higher adjusted odds ratio (aOR) 14.05 (95% confidence interval [CI], 12.74–15.49) of ICI than infants. The corridor was associated with ICI in the male pediatric group (aOR, 2.71; 95% CI, 1.08–6.84) and the balcony with the female pediatric group (aOR, 2.04; 95% CI, 1.03–4.04). In the adult group, aOR of kitchen was 1.38 (95% CI, 1.02–1.88) in females and 0.56 (95% CI, 0.48–0.66) in males. Conclusion In this study, we identified the risk factors of ICI caused by falls at home using ED-based injury surveillance data. The risk of ICI was different among places of occurrence in the home depending on the age groups and sex.

Community-based preconception care for men and women of childbearing age has been introduced in Seoul. The program aims to focus on problem areas such as low birth rate, fertility issues potentially due to late marriages, preterm or premature births, and low-birthweight in newborn babies. The district administration officials of Seoul, as well as, academics from the Korean Society of Maternal and Child Health, developed a protocol by using a questionnaire and laboratory test for screening risk factors in pregnancy. The protocol was tested on a trial basis in four local districts in Seoul from July 2017 to 2018, extended to 12 local districts in 2019, and all 25 districts in Seoul in 2020. The protocol includes AntiMullerian Hormone tests to assess women’s ovarian reserve and male health checkups that include semen analysis and physical examinations of genitalia. These tests are conducted for early detection and treatment of infertility, especially in cases of late marriages. In order to prevent women being abandoned during pregnancy (leading them to single-parenting), the protocol also emphasizes building a gender-sen sitive environment by encouraging more male participation. A monitoring group comprised of Seoul city district officials and academics from the Korean Society of Maternal and Child Health, regularly visited the local districts to observe improvements and keep the program officials up to date. In addition, the group also conducted a mobile phone survey for feedback on the program. The interest and support of the resi dents in Seoul city, and positive results and development in pregnancy care and childbirth, are needed to stabilize and extend this protocol.

Background/Aims: Chest pain in patients with obstructive coronary artery disease (OCAD) is affected by several social factors. The gender-based differences in chest pain among Koreans have yet to be investigated. Methods: The study consecutively enrolled 1,549 patients (male/female, 514/1,035; 61 ± 11 years old) with suspected angina. The predictive factors for OCAD based on gender were evaluated. Results: Men experienced more squeezing type pain on the left side of chest, while women demonstrated more dull quality pain in the retrosternal and epigastric area. After adjustment for risk factors, pain in the retrosternal area (odds ratio [OR], 1.491; 95% confidence interval [CI], 1.178 to 1.887) and aggravation by exercise (OR, 2.235; 95% CI, 1.745 to 2.861) were positively associated with OCAD. In men, shorter duration (OR, 1.581; 95% CI, 1.086 to 2.303) and dyspnea (OR, 1.610; 95% CI, 1.040 to 2.490) increased the probability for OCAD, while left-sided chest pain suggested a low probability for OCAD (OR, 0.590; 95% CI, 0.388 to 0.897). In women, aggravation by emotional stress (OR, 0.348; 95% CI, 0.162 to 0.746) and dizziness (OR, 0.457; 95% CI, 0.246 to 0.849) decreased the probability for OCAD. Conclusions This is the first study to focus on gender differences in chest pain among Koreans with angina. Symptoms with high probability for OCAD were different between sexes. Our findings suggest that patient’s medical history in pretest assessment for OCAD should be individualized considering gender.

Based on Korean data from the Research on Asian Psychotropic Prescription Pattern for Bipolar Disorder, this study tried to present prescription patterns in biopolar disorder (BD) and its associated clinical features. Based on the information obtained from the study with structured questions, the tendency of prescription pattern was studied and analyzed. Polypharmacy was predominant, including simple polypharmacy in 51.1% and complex polypharmacy in 34.2% of patients. Subjects associated with simple or complex polypharmacy were significantly younger, had higher inpatient settings, a larger portion of onset with manic episode, a shorter duration of untreated illness, a shorter duration of current episode, were more overweight, used less antidepressants and used more anxiolytics. These findings can suggest higher polypharmacy rate in more severe BD and highlight the necessity of monitoring the weight of subjects with polypharmacy.

Extended-release osmotic extended-release oral delivery system (OROS) hydromorphone is a strong synthetic opioid designed to maintain a constant blood concentration by once daily dosing. The objective of this observational study was to investigate the clinical usefulness of OROS hydromorphone in patients with cancer pain of moderate to severe intensity. Patients with cancer pain who required strong opioids were administered with OROS hydromorphone for 4 weeks. We assessed changes in pain intensity using a numerical rating scale (NRS) as well as levels of sleep disturbance, breakthrough pain, end-of-dose failure, patient satisfaction, and overall assessment of drug effectiveness based on investigator evaluation. Of the 648 enrolled patients, 553 patients were included in the full analysis set. The mean pain intensity was significantly decreased from the NRS value of 5.07 ± 1.99 to 2.75 ± 1.94 (mean % change of 42.13 ± 46.53, P < 0.001). The degree of sleep disturbance significantly improved (mean NRS change of 1.61 ± 2.57, P < 0.001), and the incidence of breakthrough pain was significantly decreased (mean NRS change of 1.22 ± 2.30, P < 0.001). The experience of end-of-dose failure also significantly decreased from 4.60 ± 1.75 to 3.93 ± 1.70, P = 0.007). The patient satisfaction rate was 72.7%, and 72.9% of investigators evaluated the study drug as effective. OROS hydromorphone was an effective and tolerable agent for cancer pain management. It effectively lowered pain intensity as well as improved sleep disturbance, breakthrough pain, and end-of-dose failure (Identifier: NCT 01273454).

Although pulmonary artery angiosarcoma is rare, it can be misdiagnosed as pulmonary embolism because of its similar clinical and diagnostic features. The diagnosis is often delayed and the misdiagnosis brings unnecessary treatment. Because we made a wrong diagnosis of pulmonary artery angiosarcoma as an acute pulmonary embolism, we did thrombolytic therapy which could be dangerous to the patient. In this case report, we focused on the clinical and echocardiographic features of pulmonary artery angiosarcoma which can be used in differentiating the diagnosis from pulmonary embolism.

BACKGROUND: An oral glucose tolerance test (OGTT) is the current method used for screening and diagnosis of gestational diabetes mellitus (GDM). OGTT is a relatively complicated procedure and is expensive. Thus, new strategies that do not require fasting or more than a single blood draw may improve the diagnosis of GDM and increase the rate of GDM testing. We investigated the utility of monitoring glycosylated hemoglobin (HbA1c) levels for the diagnosis of GDM. METHODS: The data from 992 pregnant women with estimated gestational ages ranging from 24 to 28 weeks were retrospectively reviewed. There were 367 women with plasma glucose levels > or =140 mg/dL 1 hour after a 50-g OGTT. GDM was diagnosed according to the Carpenter-Coustan criteria for a 3-hour 100 g OGTT. A HbA1c assessment was performed at the same time. RESULTS: We enrolled 343 women in this study, and there were 109 women with GDM. The area under the curve the receiver operating characteristic curve for HbA1c detection of GDM was 0.852 (95% confidence interval, 0.808 to 0.897). A HbA1c cutoff value > or =5.35% had maximal points on the Youden index (0.581). The sensitivity was 87.2% and the specificity was 70.9% for diagnosing GDM. A threshold value > or =5.35% indicated that 163 patients had GDM and that 68 (41.7%) were false positive. The positive predictive value was 58.3% at this threshold value. CONCLUSION: Despite substantial progress in methodology, HbA1c values cannot replace OGTT for the diagnosis of GDM.

Detecting signs of learning in persons diagnosed to be in a post-coma vegetative state and minimally conscious state (MCS) may modify their diagnosis. We report the case of a 65-year-old female in a vegetative state. We used microswitch-based technology that is based on patient response to eye-blinking. We followed an ABABCB design, in which A represented baseline periods, B intervention periods with stimuli contingent on the responses, and C a control condition with stimuli presented non-contingently. We observed the level of response during the B phases was higher than the level of A and C phases. This indicated the patient showed signs of learning. This state was confirmed by an evaluation through the Coma Recovery Scale-Revised (CRSR) score, and after completion of this study her CRSR score changed from 4 to 10. We believe microswitch technology may be useful to make a diagnosis of MCS and offer new opportunities for education to MCS patients.
