Objective:
We aimed to investigate the annual prevalence of intellectual disabilities (ID) and autism spectrum disorder employing claims data registered in Korean National Health Insurance Service. We also estimated the annual average of medical costs incurred from these disorders using same datasets.
Methods:
In order to obtain the prevalence, we selected patients diagnosed with ID and pervasive and specific developmental disorders (PDD) from 2007 to 2019. The ensuing annual average of medical costs was also estimated from these patients.
Results:
The annual prevalence of ID and PDD (per 100,000) between 2007 and 2019 ranged from 56.7 to 78.6 and from 22.0 to 44.6 respectively. Regarding the annual average of total medical expenditure per a patient, the expenditure of the ID group was higher than that of PDD throughout the years, as shown that the ID expenditure ranged from 769.7 to 1,501.2 US dollars as opposed to the PDD expenditure in the range of 312.5 to 570.7 US dollars. The further comparison in relation to income levels elaborated that the medical aid beneficiary group constitutes the highest one and the difference of the expenditure across the remaining income groups was not prominent although the very low group generally ranked the highest over the years.
Conclusion
The prevalence of ID and PDD constantly increased and the same trend was displayed in ensuing health expenditures throughout the period. This implies that increasing needs exist across these patients with regards to therapeutic interventions, thereby contributing to prioritizing medical policies on national perspectives.

Background:
We aimed to investigate the annual incidence of trauma and stress-related mental disorder including acute stress disorder (ASD) and post-traumatic stress disorder (PTSD) using the National Health Insurance Service Database. In addition, we estimated direct medical cost of ASD and PTSD in Korea.
Methods:
To examine the incidence, we selected patients who had at least one medical claim containing a 10th revision of the International Statistical Classification of Diseases and Related Health Problems code for ASD (F43.0) and PTSD (F43.1) and had not been diagnosed in the previous 360 days, from 2010 to 2017. We estimated annual incidence and the number of newly diagnosed patients of ASD and PTSD. Annual prevalence and direct medical cost of ASD and PTSD were also estimated.
Results:
The number of newly diagnosed cases of ASD and PTSD from 2011 to 2017 totaled 38,298 and 21,402, respectively. The mean annual incidence of ASD ranged from 8.4 to 13.7 per 100,000 population and that of PTSD ranged from 4.2 to 8.3 per 100,000 population, respectively. The incidence of ASD was found more in females and was highest among the 70–79 years of age group and the self-employed individuals group. The incidence of PTSD was also more common in the female group. However, the incidence of PTSD was highest in the 60–69 years of age group and in the medical aid beneficiaries group. The annual estimated medical cost per person of ASD ranged from 104 to 149 US dollars (USD). In addition, that of PTSD ranged from 310 to 426 USD.
Conclusion
From 2011 to 2017, the annual incidence and direct medical cost of ASD and PTSD in Korea were increased. Proper information on ASD and PTSD will not only allows us to accumulate more knowledge about these disorders themselves but also lead to more appropriate therapeutic interventions by improving the ability to cope with these trauma related psychiatric sequelae.

Background:
Korea’s aging population has raised several challenges, especially concerning healthcare costs. Consequently, this study evaluated the association of frailty transitions with healthcare utilization and costs for older adults aged 70 to 84.
Methods:
This study linked the frailty status data of the Korean Frailty and Aging Cohort Study to the National Health Insurance Database. We included 2,291 participants who had frailty measured by Fried Frailty phenotype at baseline in 2016–2017 and follow-up in 2018– 2019. We conducted a multivariate regression analysis to determine the association between their healthcare utilization and costs by frailty transition groups.
Results:
After 2 years, changes from “pre-frail” to “frail” (Group 6) and “frail” to “pre-frail” (Group 8) were significantly associated with increased inpatient days (P < 0.001), inpatient frequency (P < 0.001), inpatient cost (P < 0.001 and P < 0.01, respectively), and total healthcare cost (P < 0.001) than “robust” to “robust” (Group 1) older adults. A transition to frailty from “pre-frail” to “frail” (Group 6) resulted in a $2,339 total healthcare cost increase, and from “frail” to “pre-frail” (Group 8), a $1,605, compared to “robust” to “robust” older adults.
Conclusion
Frailty among community-dwelling older adults is economically relevant.Therefore, it is crucial to study the burden of medical expenses and countermeasures for older adults to not only provide appropriate medical services but also to prevent the decline in their living standards due to medical expenses.

Objective:
We aimed to investigate the annual incidence and direct medical cost of adjustment disorder in general population using the National Health Insurance Service Database (NHID) in Korea.
Methods:
To examine the incidence, we selected patients who had at least one medical claim for adjustment disorder and had not been diagnosed in the previous 365 days, from 2010 to 2017.
Results:
The number of newly diagnosed cases of adjustment disorder from 2011 to 2017 were total 101,922. Annual incidence of adjustment disorder was ranged from 22.0 to 36.8 per 100,000 persons. The incidence of adjustment disorder was found more in female and highest among 70–79 years of age group and medical aid beneficiaries group. Annual prevalence of adjustment disorder was in the range from 95.4 to 116.4 per 100,000 persons. Estimated annual medical cost per person of adjustment disorder was ranged from 162 to 231.4 US dollars.
Conclusion
From 2011 to 2017, the annual incidence and direct medical cost of adjustment disorder in Korea were increased. Proper information on adjustment disorder will not only allows us to accumulate more knowledge but also lead to more appropriate therapeutic interventions.

Hypereosinophilia has been associated with a variety of underlying disorders such as parasitic, fungal and mycobacterial infections, allergic disorders, collagen vascular diseases, or hypereosinophilic syndrome (HES). The association of acute lymphoblastic leukemia (ALL) and symptomatic eosinophilia is rare and only a few cases have been reported. HES probably occurs in less than 1% of all patients with ALL. The chromosomal translocation t (5; 14) (q31; q32) was cloned at the molecular level in ALL with eosinophilia. This translocation joined the immunoglobulin heavy chain region to the promoter region of the interleukin-3 (IL-3) gene in opposite transcriptional orientation. The IL-3 gene translocated with the immunoglobulin heavy chain gene may play a central role in the pathogenesis of this leukemia and the associated eosinophilia. We describe a 8-year-old boy who presented with hypereosinophilia and concurrent ALL with t (5; 14).

The myelodysplastic syndromes (MDS) are characterized by ineffective hematopoiesis associated with multilineage cytopenias leading to serious morbidity or mortality, and the additional risk of leukemic transformation. The management of patients with MDS can be very complex and varies according to both the clinical manifestations in individual patients as well as the presence of complicating medical conditions. However, therapeutic dilemmas still exist for MDS due to the multifactorial pathogenetic features of the disease, its heterogeneous stages, and the elderly patient population. For these reasons, proper guidelines for management are necessary. This review describes the proper diagnosis for MDS, decision-making approaches for optimal therapeutic options that are based on a consideration of patient clinical factors and risk-based prognostic categories, and the use of recently available biospecific drugs such as hypomethylating agents that are potentially capable of abrogating the abnormalities associated with MDS. Proper indications and methods for transplantation, response criteria, management for iron overload for highly transfused patients and specific considerations for MDS in childhood are also described. All of these topics were discussed at the third symposium of AML/MDS working party on 3 March, 2007.
