RESUMEN
Purpose@#BRCA1/2 mutations are well-known risk factors for breast and ovarian cancers in women. Risk-reducing salpingo-oophorectomy (RRSO) is the standard treatment for preventing ovarian cancer with BRCA mutations. Postmenopausal syndrome (symptoms after RRSO can be alleviated by hormone replacement therapy (HRT); however, the use of HRT in carriers of BRCA mutations has been controversial because of the concern that HRT increases the risk of breast cancer. This study aimed to evaluate the effects of HRT in BRCA mutation carriers who underwent RRSO. @*Materials and Methods@#A total of 151 carriers, who underwent RRSO between 2013 and 2020 after the diagnosis of BRCA1 or BRCA2 mutations were selected and followed up for a median of 3.03 years. Patients were divided into two groups: those who received HRT after RRSO (n=33) and those who did not (n=118). We compared the incidence of breast cancer over time between these two groups. @*Results@#There was no significant difference in the incidence of breast cancer between women who received HRT and those who did not (p=0.229). Multivariate logistic regression analysis, adjusted for age and parity revealed no significant difference in the risk of breast cancer between these two groups (hazard ratio, 0.312; 95% confidence interval, 0.039 to 2.480; p=0.278). @*Conclusion@#In this study, we found no relationship between post-RRSO HRT and breast cancer in the population with BRCA mutations. Therefore, healthcare providers may consider the alleviation of symptoms of postmenopausal syndrome through HRT in patients who underwent RRSO.
RESUMEN
Background@#Tinea capitis in adults has been increasing recently. Nevertheless, studies related to difference in tinea capitis between adults and children in Korea are scarce. @*Objective@#To investigate the clinical and mycological features of tinea capitis in adults and children. @*Methods@#The medical records of 60 adult and 58 pediatric patients with tinea capitis during a 24-year period were retrospectively examined. @*Results@#The proportion of adult patients among all patients with tinea capitis had increased from 32.3% between 1999 and 2010 to 57.5% between 2011 and 2022 (p=0.016). The proportion of postmenopausal women among all adult patients with tinea capitis was 70.0%. Among those aged <50 years, the incidence rate ratio in males to that in females was 2:1. However, among those aged ≥50 years, the incidence rate ratio in males to that in females was 1:4.7, indicating a higher incidence in females (p=0.005). Microsporum canis was the most common etiological agent (48.8%), followed by Trichophyton rubrum (36.6%). M. canis was the most prevalent dermatophyte in adults (48.8%) and children (85.0%). However, the proportion of dermatophytes other than M. canis was higher in adults (51.2%) than in children (15.0%) (p＜0.001). @*Conclusion@#Tinea capitis in adults has increased, particularly in postmenopausal women. M. canis was the most prevalent dermatophyte; however, the prevalence of other species, notably T. rubrum, was higher in adults compared with that in children. These findings are expected to offer valuable insights for the early diagnosis and treatment of tinea capitis in adults.
RESUMEN
Objective@#To evaluate the association between atopic dermatitis (AD) and suicidal behaviors in adolescent defectors among residents who escaped from North Korean (adolescent defectors, n=423) and adolescents with South Korean parents (Korean adolescents, n=540,265). @*Methods@#The study used data from the Korea Youth Risk Behavior Survey conducted from 2011 to 2019. Differences in general characteristics, health behaviors, suicidal ideation, suicide plans, suicide attempts, and AD between adolescent defectors and Korean adolescents were examined. Multiple logistic regression analysis was used to determine the association between AD and suicidal behaviors. @*Results@#The adolescent defectors group had lower AD (16.3% vs. 24.2%), poorer subjective health (10% vs. 6%), smoked more (47% vs. 18%), drank more (60% vs. 43%), lived with family less frequently (56% vs. 96%), and were more than twice as likely to have depression (42% vs. 27%), suicidal ideation (30% vs. 14%), a suicide plan (23% vs. 5%), or have made a prior suicide attempt (19% vs. 3%) compared with the Korean adolescent group (p<0.001). The adjusted odds ratio for the adolescent defectors group compared to the Korean adolescent group was 1.66 for suicidal ideation, 3.59 for suicide plans, and 4.34 for suicide attempts (p<0.001). AD was found to be associated with suicide plans and attempts in adolescent defectors and associated with suicidal ideation in Korean adolescents. @*Conclusion@#AD was significantly associated with suicide plans and suicidal attempts among adolescent defectors and suicidal ideation in Korean adolescents, based on a random sample of middle- and high-school students.
RESUMEN
After tooth extraction, alveolar bone is resorbed over time. Loss of alveolar bone and reduction of upper soft tissue poses difficulties in future implant placement and long-term survival of the implant. This case report focuses on increasing the soft and hard tissues at the implant placement site by using alveolar ridge augmentation and a xenogeneic collagen matrix as a soft tissue substitute in an extraction socket affected by periodontal disease. In each case, the width of the alveolar bone increased to 6 mm, 8 mm, and 4 mm, and regeneration of the interdental papilla around the implant was shown, as well as buccal keratinized gingiva of 4 mm, 6 mm, and 4 mm, respectively. Enlarged alveolar bone facilitates implant surgery, and interdental papillae and keratinized gingiva enable aes-thetic prosthesis. This study performed alveolar ridge augmentation on patients with extraction sockets affected by periodontal dis-ease and additionally used soft tissue substitutes to provide a better environment for implant placement and have positive effects for aesthetic and predictive implant surgery.
RESUMEN
Objective@#Immune checkpoint inhibitors have been widely used in the treatment of endometrial cancer (EC) with microsatellite instability-hypermutated (MSI-H). However, there is an unmet need for microsatellite stable (MSS) EC because of their modest activity. This study aimed to identify potential immune-related biomarkers in MSS EC. @*Methods@#One hundred and twenty-three patients with EC who underwent hysterectomy were enrolled. MSI status was determined using MSI analysis and/or immunohistochemical staining for mismatch repair proteins. Immunohistochemical analysis of programmed cell death protein 1 (PD-1), programmed death-ligand 1 (PD-L1), PD-L2, cytotoxic T-lymphocyte-associated protein 4 (CTLA-4), cluster of differentiation 3 (CD3), CD8, lymphocyte activation gene-3 (LAG-3), indoleamine 2,3-dioxygenase 1 (IDO1), phosphatase and tensin homolog (PTEN), p53, AT-rich interactive domain-containing protein 1A (ARID1A), and β-catenin was performed using tissue microarray blocks. @*Results@#Among 123 patients, 95 (77.2%) were classified as having MSS. Within EC with MSS, PD-L1 positivity was significantly associated with positive PD-1 (p<0.001), CTLA-4 (p<0.001), CD3 (p=0.002), CD8 (p<0.001), and LAG-3 (p<0.001). In the univariate analysis, positive PD-1 (odds ratio [OR]=9.281; 95% confidence interval [CI]=2.560–33.653; p<0.001), CTLA-4 (OR=5.33; 95% CI=1.418–19.307; p=0.005), CD3 (OR=5.571; 95% CI=1.746–17.775; p=0.004), CD8 (OR=6.909; 95% CI=2.647–18.037; p<0.001), and LAG-3 (OR=9.75; 95% CI=1.947–48.828; p=0.005) were significantly associated with PD-L1 positivity in MSS EC. In the multivariate analysis, LAG-3 demonstrated a significant association with positive PD-L1 expression in MSS EC (OR=5.061; 95% CI=1.534–16.693; p=0.023). @*Conclusion@#In patients with MSS EC harboring PD-L1, LAG-3 may be a potential immunotherapeutic target. Clinical trials investigating the role of anti-LAG-3 antibodies, alone or in combination with other immunotherapies, are warranted.
RESUMEN
Background@#Vulvar cancer is one of the rare gynecologic malignancies. Despite the recent increasing trend of vulvar cancer in western countries due to the increased infection of human papillomavirus, there has been no study for population-based incidence of vulvar cancer in Korea. We aimed to investigate the prevalence and treatment of vulvar cancer in South Korea between 2014 and 2018. @*Methods@#Data from patients diagnosed and treated with vulvar cancer between 2014 and 2018 were obtained from the Health Insurance Review and Assessment Service/National Inpatient Sample (National In-Patient Sample) in South Korea. @*Results@#A total of 4,636,542 women were identified through the HIRA-NIS database from 2014 to 2018, of which 259 patients were diagnosed and treated for vulvar cancer. The mean age diagnosed with vulvar cancer was 62.82 (± 14.30) years in 2014, 64.19 (± 16.79) years in 2015, and 67.40 (± 14.41) years in 2016. In terms of treatment modalities, the most frequent treatment was surgery only without chemotherapy or radiation therapy. In the age-specific prevalence analysis, vulvar cancer was the most prevalent among those over 70 years old. According to multiple regression analysis, patients’ age was significantly associated with the prevalence of vulvar cancer. Vulvar cancer was more prevalent in women with low socioeconomic status (SES) compared to those with high SES in 2018 (OR, 4.242; P < 0.001). @*Conclusion@#Considering the high prevalence of vulvar cancer in the elderly, it is necessary to establish a new strategy for early screening and treatment.
RESUMEN
The microdeletion syndrome of chromosome 2p15p16.1 (MIM: 612513) is an extremely rare contiguous gene deletion syndrome. Microdeletions of varying sizes in the 2p15-16.1 region are associated with developmental delay, intellectual disability, autism spectrum disorder, hypotonia, and craniofacial dysmorphism. Previous studies have identified two critical regions: the proximal 2p15 and distal 2p16.1 regions. BCL11A, PAPOLG, and REL genes play crucial roles in patients with 2p16.1 microdeletion. To our knowledge, only 39 patients have been reported as having 2p15p16.1 microdeletion syndrome. Here, we present another patient with 2p15p16.1 microdeletion syndrome. A nine-month-old boy was referred to our clinic for the psychomotor delay, facial dysmorphism, and congenital hypothyroidism. During his follow-up visits, he was diagnosed with global developmental delay, intellectual disability, abnormal behavior, hypotonia, microcephaly, and abnormal electroencephalography. Using a chromosomal microarray for genetic analysis, a novel, de novo, 622 kb microdeletion of 2p16.1 was identified as one of the critical regions of the 2p15p16.1 microdeletion syndrome. This is the first case of its kind in Korea. We have discussed our case and literature reviews to clarify the relationship between the genes involved and clinical phenotypes in 2p15p16.1 microdeletion syndrome.
RESUMEN
Objective@#Recent studies have detailed the genomic landscape of endometrial cancer (EC); however, no study has focused on genetic alterations in advanced EC. We performed genomic profiling of patients with advanced EC using targeted next-generation sequencing (NGS). @*Methods@#Archival tissue samples from 21 patients diagnosed with stage III and IV EC were obtained and subjected to NGS. Our data and the cancer genome atlas dataset were combined, and somatic mutation patterns were analyzed and compared according to the stage and histological type. Additionally, survival effects of specific mutated genes were analyzed. @*Results@#Somatic mutation patterns of 38 genes were identified in 263 EC samples, and the most commonly mutated genes were PTEN and PIK3CA. PTEN was the most common in endometrioid histology, while PPP2R1A was the most commonly mutated gene in serous histology. The mutation rates of PPP2R1A and TP53 were significantly higher in advanced EC sample than in stage I samples (22.5% vs. 4.3% [p<0.001] and 8.4% vs. 1.4% [p=0.021], respectively). Survival analysis of the total population and endometrioid subgroup revealed that patients with PPP2R1A mutations had significantly shorter survival than did those without mutations (p=0.005 and p<0.001, respectively). @*Conclusion@#PPP2R1A mutations might have a role in dismal prognosis of advanced EC.
RESUMEN
Since the human papillomavirus (HPV) vaccine guidelines were developed by the Korean Society of Gynecologic Oncology (KSGO) in 2011, 2016, and 2019, several recent studies on the efficacy and safety of HPV vaccines in middle-aged women and men have been reported. Furthermore, there has been an ongoing debate regarding the efficacy of the HPV vaccine in women with prior HPV infection or who have undergone conization for cervical intraepithelial neoplasia (CIN). We searched and reviewed studies on the efficacy and safety of the HPV vaccine in middle-aged women and men and the efficacy of the HPV vaccine in patients infected with HPV and those who underwent conization for CIN. The KSGO updated their guidelines based on the results of the studies included in this review.
RESUMEN
Background@#Non-obstetric surgery during pregnancy is associated with adverse obstetric and fetal outcomes. The aim of this study was to investigate the risk of adverse pregnancy outcomes for women who underwent non-obstetric pelvic surgery during pregnancy compared with that of women that did not undergo surgery. @*Methods@#Study data from women who gave birth in Korea were collected from the Korea National Health Insurance claims database between 2006 and 2016. We identified pregnant women who underwent abdominal non-obstetric pelvic surgery by laparoscopy or laparotomy from the database. Pregnancy outcomes including preterm birth, low birth weight (LBW), cesarean section (C/S), gestational hypertension, gestational diabetes, and postpartum hemorrhage were identified. The adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) for the pregnancy outcomes were estimated by multivariate regression models. @*Results@#Data from 4,439,778 women were collected for this study. From 2006–2016, 9,417 women from the initial cohort underwent non-obstetric pelvic surgery (adnexal mass resection, appendectomy) during pregnancy. Multivariate logistic regression analysis indicated that preterm birth (HR, 2.01; 95% CI, 1.81–2.23), LBW (HR, 1.62; 95% CI, 1.46– 1.79), C/S (HR, 1.13; 95% CI, 1.08–1.18), and gestational hypertension (HR, 1.35; 95% CI, 1.18–1.55) were significantly more frequent in women who underwent non-obstetric surgery during pregnancy compared to pregnant women who did not undergo surgery. When the laparoscopic and laparotomy groups were compared for risk of fetal outcomes, the risk of LBW was significantly decreased in laparoscopic adnexal resection during pregnancy compared to laparotomy (odds ratio, 0.62; 95% CI, 0.40–0.95). @*Conclusion@#Non-obstetric pelvic surgery during pregnancy was associated with a higher risk of preterm birth, LBW, gestational hypertension, placenta previa, placental abruption, and C/S. Although the benefits and safety of laparoscopy during pregnancy appear similar to those of laparotomy in regard to pregnancy outcomes, laparoscopic adnexal mass resection was associated with a lower risk of LBW.

RESUMEN
Objectives@#This study was carried out to understand the seroprevalence and risk factors for severe fever with thrombocytopenia syndrome (SFTS) among the Korea National Park Service (KNPS) workers. @*Methods@#We used the stored serum samples (763) and survey results collected from the previous investigation on scrub typhus and Lyme disease among the KNPS workers during 2016-2017. The serum samples were analyzed by double-antigen sandwich enzyme-linked immunosorbent assay, which was used to test the total antibody including IgG and IgM. @*Results@#The SFTS seroprevalence among the KNPS worrkers was 1.4%. In multivariate logistic analysis, the national park exploration programs (odds ratio, 3.48; 95% confidence interval, 1.01-12.01) was significantly associated with the seroprevalence of SFTS. @*Conclusion@#This study was the first serological study of SFTS among forestry workers in South Korea. Although the KNPS workers are at a high-risk group of SFTS, the prevention activities related to the working environment and habit was insufficient. Thus, systematic prevention education and training for the KNPS workers need to be strengthened.
RESUMEN
Objective@#This study aimed to investigate the clinicopathologic risk factors for type-specific persistence of high-risk human papillomavirus (hrHPV) and residual/recurrent cervical intraepithelial neoplasia (CIN) after surgical treatment. @*Methods@#Patients with CIN-2/3 who underwent conization or loop electrosurgical excision procedure (LEEP) at Korea University Hospital were enrolled. All patients underwent hrHPV testing and genotyping before conization or LEEP followed by both hrHPV genotyping and cytology. The significance of associations between patient characteristics and persistence of infection were assessed by multivariate logistic regression analyses. @*Results@#Among 398 women with pathologically confirmed CIN-2/3, 154 (38.7%) patients showed hrHPV persistence after surgical treatment. In multivariate analysis, high preoperative hrHPV load (P<0.05; odds ratio [OR], 2.063), presence of CIN-2 at treatment (P<0.01; OR, 2.732), and multiple hrHPV infections (P<0.001; OR, 4.752) were associated with hrHPV persistence. HPV 53 was the most likely to persist after treatment (24/43, 55.8%). The risk of residual/recurrent CIN-2/3 was higher in persistent infection with HPV 16 than other types (P<0.05). Menopause (P<0.001; OR, 3.969), preoperative and postoperative hrHPV load (P<0.05; OR, 2.430; P<0.05; OR, 5.351), and infection with multiple hrHPV types (P<0.05; OR, 2.345) were significantly related to residual/recurrent CIN following surgical treatment. @*Conclusion@#HPV load before treatment and infection with multiple hrHPV types were predictors of postoperative hrHPV persistence. HPV 53 was the type most likely to persist, but HPV 16 was the type that was most closely associated with residual/recurrent CIN-2/3.

RESUMEN
There have been ongoing social discussions on revision of the abortion law since the Constitutional Court ruled it nonconformity to the constitution on April 11, 2019. Thus, Korean Society of Obstetrics and Gynecology, Korean Society of Maternal Fetal Medicine, Korean College of Obstetricians and Gynecologists, and Korean Association of Obstetricians and Gynecologists organized 'special committee for abortion law' to support social discussion on the revision of the abortion law, and they prepared official opinions of obstetrics for medical issues including doctors' right to refuse abortion. In the future, the committee will continue to adapt to changes of medical environment especially after the revision of the abortion law by collecting its members' feedbacks.
RESUMEN
Background@#Many studies focus on herpes zoster in Korean dermatologic literature. However, there are few studies on sacral herpes zoster associated with voiding dysfunction have been reported. @*Objective@#This study aimed to investigate the clinical features of sacral herpes zoster associated with voiding dysfunction. @*Methods@#During a 21-year-period from 1997 to 2018, 18 patients with sacral herpes zoster associated with voiding dysfunction were evaluated in terms of the type of urinary symptoms, duration based on the onset of urinary symptoms, requirement of an indwelling Foley catheter, medication, and time required for normal voiding. A statistical analysis was performed to determine whether there was a difference between the two groups in the time required for normal voiding. The first comparison groups included a group with a catheter and a group without a catheter, and the second comparison groups included a group with medication and a group without medication. @*Results@#The average time required for normal voiding in patients with an indwelling Foley catheter (51.4±42.8 days) was significantly longer than in patients without an indwelling Foley catheter (40.4±91.8 days) (p=0.027). The average time required for normal voiding in patients with medication (65.2±79.4 days) was significantly longer than in patients without medication (7.5±2.7 days) (p=0.001). @*Conclusion@#The possibility of voiding dysfunction should not be overlooked in patients with sacral herpes zoster. Moreover, the severity of voiding dysfunction is an important prognostic factor for the time required for the relief of voiding dysfunction. Therefore, we should pay attention when a patient develops urinary dysfunction.
RESUMEN
ObjectivesCoronavirus disease 2019 (COVID-19) outbreaks in nursing facilities can easily lead to a high rate of infection and fatality. A surge in newly infected cases in the first quarter of 2020 in Gyeongsan-si, in the Republic of Korea, was followed by several outbreaks in nursing facilities in the same area. The aim of this study is to report on the epidemiological investigation and the management to reduce the infection rate in nursing facilities for older adults.MethodsThe municipal government and the Korea Centers for Disease Control and Prevention performed an epidemiological investigation into 5 nursing facilities that reported a high number of COVID-19 infection cases from February to May 2020. COVID-19 infected cases in the facilities were investigated to identify the infection routes, and the fatality rate of the 5 facilities.ResultsThe 5 facilities had a combined fatality rate of 12.2% (9 deceased among the 74 infected cases). The median age of the deceased was 87 years old (range: 82–91). The infection was first identified on February 27th, 2020, peaked on March 6th, and was last detected on March 24th, 2020.ConclusionDifficulties specific to such facilities included the delay in the recognition of symptoms and limitation in distancing. Tailored strategies such as daily monitoring of symptoms and proactive COVID-19 screening of quarantined residents, contributed to a decline in the infections in the facilities.
RESUMEN
Whole lung lavage (WLL) is a therapeutic procedure to remove accumulated material by infusing and draining the lungs with lavage fluid. This procedure has been regarded as the current standard of care to treat pulmonary alveolar proteinosis. However, the WLL protocol has not yet been standardized and the technique has been refined and modified a number of times. A rapid infusion system is a device used to infuse blood or other fluids at precise rates and normothermic conditions. This device is not typically used in WLL, which relies on the passive infusion of fluids using the gravitational force. However, in this study we performed WLL using a rapid infusion system, since we aimed to take advantage of its shorter operation time and greater degree of control over fluid volume and temperature. The patient’s symptoms improved without the occurrence of any complications.
