Is Human Mpox a New Sexually Transmitted Infection in Korea That Should Be Monitored?: Gilho Lee; Urogenit Tract Infect 2023;18(2):35-44. Published online August 31, 2023; DOI: https://doi.org/10.14777/uti.2023.18.2.35

Abstract PDF Supplementary Material PubReader ePub: Human monkeypox (mpox) outbreaks have been reported in more than 110 countries, with more than 86,930 confirmed cases. The World Health Organization has realized the seriousness of personal transmission and has declared a global health emergency against the infection. Traditionally, contact with infected animals in a few endemic countries has been a major transmission route of the mpox virus. On the other hand, the global mpox outbreak in 2022 has been primarily associated with sexual networks of men who have sex with men (MSM) and bisexual men exhibiting high-risk behaviors. Their common symptoms are initial fever, headache, swollen lymph nodes, and subsequent skin rashes. These presentations did not consistently occur in the 2022 outbreak. Many patients presented with skin lesions on the anogenital areas without prodromal symptoms. In addition, the atypical characteristics of the recent outbreak may result in a misdiagnosis of other skin lesions, such as chickenpox. Furthermore, infected persons are frequently co-infected with sexually transmitted infections (STIs) with similar skin lesions. The newly confirmed cases in Korea on April 2023 must have been infected through community transmission because these new patients had not traveled overseas in the past three months. Therefore, mpox is something that everybody should be concerned about in Korea. Medical practitioners must know the characteristics of the infection because patients with mpox may visit their offices with some genital lesions or other STIs. The clinical information from this paper may broaden and deepen the understanding of human mpox and curb the early transmission of the infection.

Characteristics and Treatment Trends for Emphysematous Pyelonephritis in Korea: A 10-Year Multicenter Retrospective Study: Seung-Kwon Choi, Koo Han Yoo, Jeong Woo Lee, Seung Il Jung, Eu Chang Hwang, Joongwon Choi, Woong Bin Kim, Jung Sik Huh, Jin Bong Choi, Yeonjoo Kim, Jae Min Chung, Ju-Hyun Shin, Jae Hung Jung, Hong Chung, Sangrak Bae, Tae-Hyoung Kim; Urogenit Tract Infect 2021;16(2):49-54. Published online August 31, 2021; DOI: https://doi.org/10.14777/uti.2021.16.2.49

Abstract PDF PubReader ePub: Purpose: This study examined the characteristics, current treatment trends, and outcomes of patients with emphysematous pyelonephritis (EPN) in Korea.
Materials andMethods: Two hundred and seventeen patients diagnosed with EPN were evaluated using abdominal computed tomography in 2011-2021 at 15 institutes in Korea. The patients’ demographic and clinical characteristics, treatment modalities, and treatment outcomes were analyzed. The total study period was divided arbitrarily into groups A (2011-2014), B (2015-2017), and C (2018-2021) to analyze the trends in the EPN treatment.
Results: The mean age of the patients was 65.1 years; there were more female patients (74.2%) than male patients. The overall mortality rate was 10.6%. Ninety-five (43.8%), 98 (45.2%), and 24 (11.0%) patients were treated with medical, minimally invasive, and surgical management, respectively; the corresponding mortality rates were 13.7%, 6.1%, and 16.7%. There was no significant change in the proportion of patients treated with medical management over time (group A=46.5%, group B=47.0%, and group C=38.8%). The proportion of patients treated with minimally invasive management gradually increased over time (group A=35.2%; group B=43.9%; group C=55.0%), while those who underwent surgical management decreased gradually over time (group A=18.3%, group B=9.1%, and group C=6.3%). No differences in mortality rates were observed between the groups.
Conclusions: EPN with medical and minimally invasive management had a relatively high treatment success rate, which increased gradually, while surgical management decreased gradually over time in Korea. The mortality rate was relatively lower than that reported in studies published before the 2010s.

Syphilis Notification Systems in Korea over the Last 20 Years: Yumi Seo, Gilho Lee; Urogenit Tract Infect 2021;16(1):16-23. Published online April 30, 2021; DOI: https://doi.org/10.14777/uti.2021.16.1.16

Abstract PDF Supplementary Material PubReader ePub: Purpose: The syphilis notification system has been revised three times in Korea during the last 20 years. Accordingly, we evaluated the performance of the three systems by analyzing data from the Korea Disease Control and Prevention Agency (KDCA).
Materials and Methods: We analyzed trends of stage 1, 2, and congenital syphilis cases reported in the KDCA from 2001 to 2010 in the 1st sentinel (S1), from 2011 to 2019 in the 1st universal (U1), and 2020 in the 2nd sentinel (S2) notification system.
Results: A total of 21,820 syphilis cases were reported, 9,177 cases in S1, 12,321 in U1, and 322 in S2, respectively. The reported cases can be presented in the form of four expanding waves across the time period. Although the most commonly reported age group with infection was 20-29 years in all three reporting systems, the pattern of infections was different; the number of older patients was relatively high in the S1 group while the number of syphilis cases declined sharply in the older than 20-29 old age group in the U1 and S2 systems. Also, there was a sex-based difference in the three groups; the data from S1 were female-dominant but the data in U1 and S2 were male-dominant.
Conclusions: Our results showed that the universal notification system (U1) is superior in both the quantity and quality of data to the previous sentinel system (S1). The results from the new system, S2, are similar to those from U1.
