BACKGROUND

Waiting time of patients from a consult with a primary care physician to a specialist is poorly understood. It is one indicator of health service delivery and patient satisfaction. Patients consider waiting for a specialist consult for more than three months too long and unacceptable.

To describe the sociodemographic and clinical factors associated with length of referral waiting time.

Cross-sectional retrospective chart review of patient records in a tertiary government hospital from 2015 to 2019.

A total of 366 charts were reviewed. Many of the patients referred to other specialty clinics were middle-aged adults and females. Median wait times for medical and surgical specialties were 11 (IQR: 0-29) and 18 (IQR: 6-35) days, respectively (p=0.003). Nutrition, rehabilitative medicine, and family health unit received the most number of referrals among non-surgical fields. Ophthalmology, otorhinolaryngology, and general surgery received the highest number of referrals among the surgical fields. Referral waiting times were longest for cardiology (median: 125, IQR: 91-275 days) and shortest for nutrition (median: 0, IQR: 0-6 days).

Waiting times from a primary care clinic to a specialty clinic at a tertiary government hospital vary based on urgency, specialty clinic, purpose of referral, presence of comorbidities, and chronicity of condition. Clinical factors found to be significantly associated with referral waiting time include urgency, type of clinic, and purpose of referral.

Immune checkpoint inhibitors (ICIs) have been changing the paradigm of cancer treatment. However, immune-related adverse effects (irAEs) have also increased with the exponential increase in the use of ICIs. ICIs can break up the immunologic homeostasis and reduce T-cell tolerance. Therefore, inhibition of immune checkpoint can lead to the activation of autoreactive T-cells, resulting in various irAEs similar to autoimmune diseases. Gastrointestinal toxicity, endocrine toxicity, and dermatologic toxicity are common side effects. Neurotoxicity, cardiotoxicity, and pulmonary toxicity are relatively rare but can be fatal. ICI-related gastrointestinal toxicity, dermatologic toxicity, and hypophysitis are more common with anti- CTLA-4 agents. ICI-related pulmonary toxicity, thyroid dysfunction, and myasthenia gravis are more common with PD-1/PD-L1 inhibitors. Treatment with systemic steroids is the principal strategy against irAEs. The use of immune-modulatory agents should be considered in case of no response to the steroid therapy. Treatment under the supervision of multidisciplinary specialists is also essential, because the symptoms and treatments of irAEs could involve many organs. Thus, this review focuses on the mechanism, clinical presentation, incidence, and treatment of various irAEs.

PURPOSE: We used a questionnaire to explore perceptions and clinical practice patterns of Korean pediatric ophthalmologists in terms of amblyopia.METHODS: From September to November 2018, we conducted a web-based questionnaire survey of 99 specialists of the Korean Association for Pediatric Ophthalmology and Strabismus who operated ophthalmology clinics in Korea. We received 56 responses (56.57%) and retrospectively analyzed the data.RESULTS: The average specialist age was 44.0 ± 9.7 years. The mean age of treated amblyopia patients was 3 to 5 years (69.6%); the most common amblyopia was refractive anisometropic amblyopia (75.0%). On average, treatment commenced at 4 years of age (53.6%); child and parent co-operation most significantly influenced treatment success (46.4%). The preferred test was cycloplegic refraction (96.4%) and the preferred treatment occlusion therapy (100%) with glasses correction (98.2%). Occlusion therapy was most commonly performed for 2 hours/day (69.6%); the minimum age for eyeglasses prescription was 2.10 ± 1.18 years. Only three respondents (5.36%) prescribed contact lenses and only one (1.79%) performed refractive surgery.CONCLUSIONS: In Korea, amblyopia treatment is based on occlusion therapy and glasses correction. However, the time of treatment commencement, the duration of occlusion therapy, and the glasses used for correction varied. It is necessary to develop guidelines for amblyopia treatment; these should reflect current medical conditions.

BACKGROUND: The incidence of asthma exacerbation (AE) and the predictive value of spirometry and fractional exhaled nitric oxide (FeNO) in school children have not been evaluated.OBJECTIVE: We sought to evaluate the efficacy of spirometry measurement and FeNO monitoring for predicting AE in school children in the Cheongju area in Korea.METHODS: With parental agreement, we studied 170 students aged 7–12 years. Children were evaluated by an asthma specialist using baseline spirometry, skin prick test, seasonal FeNO measurement, and asthma control test. The study participants underwent a physical examination and their medical history was also evaluated by the specialist. They were assessed for asthma control status during regular doctor visits for 1 year.RESULTS: In total, 160 children (94.1%) completed follow-up and FeNO monitoring. Of which, 26 children (16.3%) had AE. AE was associated with male children and children with allergic rhinitis (p < 0.05). While, children with AE tended to have higher FeNO than those without AE, no significant difference was found. The maximum value of FeNO ≥35 ppb was associated with AE (p < 0.05). Children with AE had a significantly decreased baseline forced expiratory volume in 1 second/forced vital capacity (FEV₁/FVC), %predicted, forced expiratory flow at 25%–75% of FVC (FEF(25%–75%)). FEV₁/FVC < 80% was associated with AE in children regardless of inhalant allergen sensitization (all p < 0.05).CONCLUSION: Baseline spirometry had a predictive value of AE in school children. Sensitive spirometric parameters such as FEV₁/FVC and FEF(25%–75%) can be used as prognostic factors to predict future childhood AE. FeNO value ≥ 35 ppb during monitoring was associated with AE in school children.

BACKGROUND: Though clinical practice guidelines (CPGs) for cardiac rehabilitation (CR) are an effective and widely used treatment method worldwide, they are as yet not widely accepted in Korea. Given that cardiovascular disease is the second leading cause of death in Korea, it is urgent that CR programs be developed. In 2008, the Government of Korea implemented CR programs at 11 university hospitals as part of its Regional Cardio-Cerebrovascular Center Project, and 3 additional medical facilities will be added in 2019. In addition, owing to the promotion of CR nationwide and the introduction of CR insurance benefits, 40 medical institutions nationwide have begun CR programs even as a growing number of medical institutions are preparing to offer CR. The purpose of this research was to develop evidence-based CPGs to support CR implementation in Korea. METHODS: This study is based on an analysis of CPGs elsewhere in the world, an extensive literature search, a systematic analysis of multiple randomized control trials, and a CPG management, development, and assessment committee comprised of 33 authors—primarily rehabilitation specialists, cardiologists, and thoracic surgeons in 21 university hospitals and 2 general hospitals. Twelve consultants, primarily rehabilitation, sports medicine, and preventive medicine specialists, CPG experts, nurses, physical therapists, clinical nutritionists, and library and information experts participated in the research and development of these CPGs. After the draft guidelines were developed, 3 rounds of public hearings were held with staff members from relevant academic societies and stakeholders, after which the guidelines were further reviewed and modified. RESULTS: CR involves a more cost-effective use of healthcare resources relative to that of general treatments, and the exercise component of CR lowers cardiovascular mortality and readmission rates, regardless of the type of coronary heart disease and type and setting of CR. CONCLUSION: Individualized CR programs should be considered together with various factors, including differences in heart function and lifestyle, and doing so will boost participation and adherence with the CR program, ultimately meeting the final goals of the program, namely reducing the recurrence of myocardial infarction and mortality rates.

Acute limb ischemia (ALI) represents one of the most common emergent scenarios encountered by a vascular specialist. Despite expedient revascularization, high rates of limb loss are reported along with high mortality rates which are second only to ruptured abdominal aortic aneurysms. Surgical revascularization is standard of care. Endovascular techniques as an alternative have emerged to be appropriate first line therapy when addressing the threatened limb. We review the etiology and classification of ALI and current endovascular techniques and evidence to date in the management of patients acutely presenting with extremity ischemia.

PURPOSE: Anaphylaxis and asthma exacerbation could be life-threatening medical emergencies. The 119 (911 in the United States) rescue teams are at the forefront of such emergency conditions. Early recognition and proper prehospital management by 119 rescuers are important. We evaluated the awareness of 119 rescuers of anaphylaxis and asthma exacerbation in Korea. METHODS: Between May 17 and June 28 of 2018, a total of 180 rescuers were recruited from Gyeonggi-do province, Korea. The 90-minute educational sessions on anaphylaxis and asthma exacerbation were provided by an allergy specialist, which included some lectures and a hands-on workshop on self-injectable epinephrine autoinjector. A questionnaire survey with the same content was performed before and after education to assess the improvement in awareness. It had 2 domains: anaphylaxis awareness and asthma awareness. RESULTS: After education, awareness score for anaphylaxis increased from an average of 3.1 (51.7%) to 5.5 (91.7%). Particularly, the effect of education on the use of epinephrine, the most crucial treatment for anaphylaxis, was greatest. The awareness score for asthma after education increased from an average of 21.3 (78.9%) to 25.1 (93%). The effect of education on treatment and management of asthma was greatest. CONCLUSION: The 119 rescuers could be the first medical personnel at the forefront of anaphylaxis and asthma exacerbation. Hence, it is important to increase their awareness of anaphylaxis and asthma exacerbation. A simple educational activity can dramatically change the level of awareness.

Sleep is well known to be important to health and well-being, creativity, memory consolidation, and cognitive functions. However, sleep disorder patients sometimes had some limitation to get proper diagnosis and treatments. Now we live in an era of big change, so called the Fourth Industrial Revolution, which is characterized by mobile internet connectivity and artificial intelligence. Sleep medicine also started to change to patients-centered medicine with technical enhancement. To date, lots of smartphone applications and wearable device for monitoring sleep have appeared but not been validated enough against polysomnography. As another topic, big data receives lots of attention among sleep specialists. It is believed that big data would provide the basis of personalized healthcare. Here, we will discuss about new trend of sleep medicine involving mobile health such as telemedicine, smartphone, wearable device, and big data.

PURPOSE: This study was performed to investigate the current status of pediatric palliative care provision and how it is perceived by the palliative care experts. METHODS: A descriptive study was conducted with 61 hospice institutions. From September through October 2017, a questionnaire was completed by experts from the participating institutions. Data were analyzed using SPSS 21.0. RESULTS: Among 61 institutions, palliative care is currently provided for pediatric cancer patients by 11 institutions (18.0%), all of which are concentrated in Seoul, Incheon and Gyeonggi and Gyengsang provinces; 85.2% of all do not plan to provide specialized pediatric palliative care in the future. According to the experts, the main barriers in providing pediatric palliative care were the insufficient number of trained specialists regardless of the delivery type. Experts said that it was appropriate to intervene when children were diagnosed with cancer that was less likely to be cured (33.7%) and to move to palliative care institutions when their conditions worsened (38.2%); and it was necessary to establish a specialized pediatric palliative care system, independent from the existing institutions for adult patients (73.8%). CONCLUSION: It is necessary to develop an education program to establish a nationwide pediatric palliative care centers. Pediatric palliative care intervention should be provided upon diagnosis rather than at the point of death. Patients should be transferred to palliative care institutions after intervention by their existing pediatric palliative care team at the hospital is started.

PURPOSE: To introduce novel findings of polypoidal choroidal vasculopathy (PCV) via optical coherence tomography angiography (OCTA) METHODS: This study is a retrospective chart review of 16 patients (16 eyes) with PCV. OCTA (Avanti RTVue XR) findings were evaluated and selected for analysis after agreement by two retina specialists . RESULTS: Twenty one polyps in 16 eyes (16 patients) with PCV were included in this study. The mean patient age was 67 years (13 men and three women). The shape of polypoidal lesions on OCTA at initial were halo (five polyps), rosette (seven polyps), and vascular network (nine polyps). Eight months after anti-vascular endothelial growth factor treatment, in a total of four eyes, seven polyps could be followed up completely, the two halo type polypoidal lesions changed to rosette and vascular network type. The lesions of three rosette and two vascular network type lesions did not change in shape. In addition, the size of the polypoidal lesions (one among two halo types, two among three rosette types, and two among two vascular network types) decreased, but one halo type did not change and one rosette type increased in size on OCTA. CONCLUSIONS: En-face OCTA enabled us to categorize novel types of PCV with polypoidal lesions.
