OBJECTIVE: Moyamoya disease (MMD) is a cerebrovascular occlusive disease of the bilateral internal carotid arteries that causes a compensatory abnormal vascular network at the base of brain. The rare incidence and various surgical techniques applied have limited the clinical research on MMD. METHODS: We conducted a retrospective analysis of the surgical outcome of 410 pediatric MMD patients. All patients were treated in a relatively uniform scheme at a single institution. The surgical procedures

The study confirmed that EIMs are more prevalent among IBD patients than among the general population of Korea. The prevalence of EIMs in IBD patients suggests the need for greater attention and effort in clinical practice.

Maintaining residual renal function (RRF) is a crucial issue in peritoneal dialysis (PD). Incremental dialysis is the practice of initiating PD exchanges less than four times a day in consideration of RRF, and increasing dialysis dose in a step-wise manner as the RRF decreases. We aimed to compare the outcomes of incremental PD and full-dose PD in terms of RRF preservation and other outcomes. This was a single-center, observational study. Data were extracted retrospectively from a cohort of inci

Risk factors for CIN are prevalent among the patients undergoing CECT. Preventive measures were seemingly underutilized and a system is needed to improve preventive care.

OBJECTIVE: Although an association between moyamoya disease (MMD) and renovascular hypertension has been acknowledged, the literature on systemic hypertension without renal artery stenosis among patients with MMD is scarce. The authors aimed to evaluate the prevalence and risk factors of hypertension using data from MMD patients who visited an outpatient clinic of a pediatric neurosurgical department in 2016. METHODS: The authors evaluated the blood pressure (BP) of pediatric MMD patients at the

E valuation of scientific evidence in the medical literature is based on the research methodology, which can be the fundamental tool for medical professionals to improve their practice. Since analytic studies usually provide evidence for generating hypotheses and selecting appropriate research designs, this article aims to review the methods for evaluating the study quality in randomized controlled trials (RCTs), cohort studies, and case-control studies. Critical appraisal of systematic errors i

In Korea, FSWs were not practicing enough self-protection at work with a high prevalence of C. trachomatis. Education for constant practice of protection against sexually transmitted diseases is needed, especially for younger FSWs.

Considering the increasing trend of PTNB, more attention needs to be paid to patients with risk factors for severe pneumothorax.

INTRODUCTION: Few studies have focused on enhancing causality and yielding unbiased estimates on the effectiveness of bystander cardiopulmonary resuscitation (BCPR) on the outcomes of out-of-hospital cardiac arrest (OHCA) in a real-world setting. Therefore, this study evaluated the effect of BCPR on the outcomes of OHCA and its differences according to the characteristics of OHCA. METHODS: This study enrolled all patients with OHCA of cardiac etiology treated by emergency medical services (EMS)

Alpha blockers for BPH may increase the risk of fracture in elderly patients who have comorbidities and take the concomitant medications. Alpha blockers need to be prescribed with caution, although some have high prostate specificity.

AIMS: The impact of adherence to oral anticoagulation has not been reported in terms of absolute risk, which would enhance patients' understanding and treatment adherence. METHODS AND RESULTS: This retrospective cohort study analysed data from the National Health Insurance Database of Korea, from January 2010 to December 2018, on 84 227 patients with non-valvular atrial fibrillation (NVAF). The participants were analysed according to their overall adherence to oral anticoagulants (OACs) and furt

BACKGROUND: Medical conditions and medications may be associated with motor vehicle collisions (MVCs), which pose a major public health problem worldwide. Further epidemiological assessment is necessary for certain diseases and medications. Moreover, since disease aetiology and patterns of medication use may differ among ethnicities and healthcare systems, a population-specific approach is necessary. The present epidemiological study is designed to assess the medical conditions and medications a
